Description

本発明は、制御機構に関する。 The present invention relates to a control mechanism.

従来、不整地等で作業を行う建設ロボットや災害対応ロボット等の車両において、各車輪の接地を確保して車体の荷重を各車輪へと配分する(以下、荷重配分)と共に、車体の水平と安定を保つために車体の姿勢を制御する(以下、姿勢制御)ための制御機構が提案されている。このような制御機構としては、例えば、バネを使用したサスペンション機構により荷重配分すると共に、作業時に車両に外付けのアウトリガ等を設置して車体を支えることで姿勢制御する制御機構が提案されている。しかし、このような機構では、上述したように作業時に車両にアウトリガ等を設置する必要があり、作業時の手間やコストが増大してしまう可能性がある。 Conventionally, in vehicles such as construction robots and disaster response robots that work on rough terrain, the ground contact of each wheel is secured and the load of the vehicle body is distributed to each wheel (hereinafter referred to as load distribution), and the vehicle body is leveled. A control mechanism for controlling the posture of the vehicle body to maintain stability (hereinafter referred to as posture control) has been proposed. As such a control mechanism, for example, a control mechanism has been proposed in which the load is distributed by a suspension mechanism using a spring and the attitude is controlled by installing an external outrigger or the like on the vehicle to support the vehicle body during work. .. However, in such a mechanism, as described above, it is necessary to install an outrigger or the like on the vehicle during work, which may increase labor and cost during work.

また、他の制御機構としては、各車輪に上下方向のアクチュエータを取り付け、各車輪の荷重とストローク及び車体の傾斜等をセンサで計測しながら各車輪のストロークを制御することにより、荷重配分及び姿勢制御を同時に行うアクティブサスペンション方式が提案されている。しかし、この方式では多くのセンサが必要であると共に、アクチュエータの応答性能を補完するためのバネを併用する必要があり、機構全体が複雑化してしまい、さらに、常にアクチュエータで車体を支えるためエネルギー消費が大きく、コストが増大してしまう可能性がある。 In addition, as another control mechanism, a vertical actuator is attached to each wheel, and the stroke of each wheel is controlled while measuring the load and stroke of each wheel and the inclination of the vehicle body with a sensor to control the load distribution and attitude. An active suspension system that controls at the same time has been proposed. However, this method requires many sensors and also requires the use of a spring to complement the response performance of the actuator, which complicates the entire mechanism and consumes energy because the actuator always supports the vehicle body. Is large, and the cost may increase.

また、上記のようなバネを省略した他の制御機構としては、4輪を連動させて上下動させる機構により車輪の接地を確保して荷重配分すると共に、ワイヤや流体式サスペンションを用いて車体の前後左右の傾斜を制御することにより姿勢制御を行う機構が提案されている(例えば、特許文献1参照)。 In addition, as another control mechanism that omits the spring as described above, the four wheels are interlocked and moved up and down to secure the ground contact of the wheels and distribute the load, and the wire and the fluid suspension are used to distribute the load. A mechanism for controlling the posture by controlling the inclination of the front, back, left and right has been proposed (see, for example, Patent Document 1).

特開平10−181330号公報Japanese Unexamined Patent Publication No. 10-18133

しかしながら、上記の特許文献1に記載されたような技術では、上記バネを省略できるものの、上述したようにワイヤや流体式サスペンションを用いる必要があり、機構全体としては複雑であるため、様々な問題が生じる可能性があった。具体的には、上記のワイヤを用いた機構では、複雑なワイヤの取り回しが必要でワイヤの伸びが生じる可能性があった。また、上記の流体式サスペンションを用いた機構では、油漏れが生じて姿勢が変化してしまう可能性があるため、車輪のサスペンションストロークを検出して制御する機構が必要であった。そこで、より簡素化された機構により、荷重配分及び姿勢制御が可能な制御機構が要望されていた。 However, in the technique described in Patent Document 1 above, although the spring can be omitted, it is necessary to use a wire or a fluid suspension as described above, and the mechanism as a whole is complicated, so that there are various problems. Could occur. Specifically, in the above-mentioned mechanism using wires, complicated wire routing is required, and there is a possibility that the wires may be stretched. Further, in the mechanism using the fluid suspension described above, there is a possibility that oil leakage occurs and the posture changes. Therefore, a mechanism for detecting and controlling the suspension stroke of the wheel is required. Therefore, there has been a demand for a control mechanism capable of load distribution and attitude control by a simpler mechanism.

本発明は、上記に鑑みてなされたものであって、極めて簡素な機構により荷重配分及び姿勢制御ができ、コストの削減や利用性の向上が可能な制御機構を提供することを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide a control mechanism capable of load distribution and attitude control by an extremely simple mechanism, reducing costs and improving usability.

First, the basic concept of the embodiment of [I] will be described, then the specific contents of the embodiment of [II] will be described, and finally, a modification of the embodiment of [III] will be described. However, the present invention is not limited to the embodiments.

〔I〕実施の形態の基本的概念
まず、実施の形態の基本的概念について説明する。各実施の形態は、制御対象物を制御する制御機構に関する。ここで、「制御対象物」とは、各実施の形態に係る制御機構によって制御される対象となる物であって、各実施の形態では走行可能な車両であるものとするが、これに限らず、走行不可能な物でも構わない。また、制御対象物は、複数の「接地部」と、「本体部」と有する。「接地部」とは、接地対象面(後述する)に対して接地し得る部分であって、以下では走行用の「車輪」とするが、これに限らず走行用のもの以外も含む概念である。また、「本体部」とは、複数の接地部によって支持される部分であり、以下では「車体」とする。
[I] Basic concept of the embodiment First, the basic concept of the embodiment will be described. Each embodiment relates to a control mechanism that controls a controlled object. Here, the "control object" is an object to be controlled by the control mechanism according to each embodiment, and is a vehicle that can travel in each embodiment, but is limited to this. It doesn't matter if it is impossible to drive. Further, the controlled object has a plurality of "grounding portions" and a "main body portion". The "grounding part" is a part that can be grounded with respect to the grounding target surface (described later), and is hereinafter referred to as a "wheel" for traveling, but the concept is not limited to this and includes other than those for traveling. is there. Further, the "main body portion" is a portion supported by a plurality of ground contact portions, and will be referred to as a "body body" below.

また、「制御する」とは、制御対象物を機械的に動かすことであり、例えば、「荷重配分」、「姿勢制御」、及び「車高調整」を含む。ここで、「荷重配分」とは、車輪が接地して各車輪に荷重を配分するように制御することであり、例えばすべての車輪が接地するような制御を含むが、これに限らず、いずれかの車輪が浮いていても構わない。ここで、「接地」とは、車輪が浮いていない状態であり、例えば接地対象面に接していることに限らず、接地対象面上の障害物や段差に乗り上げている状態を含む。なお、「接地対象面」とは、車両が接地し得る面であり、例えば地面であって、各実施の形態では説明の便宜上、接地対象面は水平面とする。また、「姿勢制御」とは、制御対象物の本体部(例えば、「車体」)の傾斜角度を変更することであり、例えば車体が水平になるように、車体の前後方向の傾斜及び左右方向の傾斜の両方を調整することを含むが、これに限らず、車体の前後方向の傾斜や左右方向の傾斜のいずれかのみを調整すること等も含む。また、「車高調整」とは、車高(接地対象面から車体までの距離)を変更することである。また、各実施の形態の車両の用途は任意であり、例えば不整地等で作業を行う建設ロボットや災害対応ロボットとして利用できるが、これに限らない。 Further, "controlling" means mechanically moving a controlled object, and includes, for example, "load distribution", "attitude control", and "vehicle height adjustment". Here, the "load distribution" is to control so that the wheels touch the ground and distribute the load to each wheel, and includes, for example, control that all the wheels touch the ground, but is not limited to this. It doesn't matter if the wheels are floating. Here, the “ground contact” is a state in which the wheels are not floating, and includes, for example, not only in contact with the ground contact target surface but also in a state of riding on an obstacle or a step on the ground contact target surface. The "grounding target surface" is a surface on which the vehicle can touch the ground, for example, the ground, and in each embodiment, the grounding target surface is a horizontal plane for convenience of explanation. Further, "attitude control" is to change the tilt angle of the main body of the controlled object (for example, "vehicle body"). For example, the vehicle body is tilted in the front-rear direction and the left-right direction so that the vehicle body is horizontal. It includes, but is not limited to, adjusting both the inclination of the vehicle body in the front-rear direction and the inclination in the left-right direction. Further, "vehicle height adjustment" is to change the vehicle height (distance from the ground contact target surface to the vehicle body). Further, the use of the vehicle of each embodiment is arbitrary, and it can be used as, for example, a construction robot or a disaster response robot that works on rough terrain, but is not limited to this.

It is configured to include a control unit 100. In FIG. 1, for convenience of illustration, the illustration of each part of the vehicle body 70 and the like is omitted. Hereinafter, the X direction in each figure is referred to as a "width direction" or a "left-right direction", and particularly the + X direction is referred to as a "right direction" and the −X direction is referred to as a "left direction" as necessary. Further, the Y direction is referred to as a "depth direction" or a "front-back direction", and in particular, the + Y direction is referred to as a "forward direction" and the -Y direction is referred to as a "rear direction". Further, the Z direction is referred to as "height direction", particularly the + Z direction is referred to as "upward direction" and the −Z direction is referred to as "downward direction". Further, the following description of "moving (or turning) in the same direction with each other" indicates that at least two things move (or turn) in the same direction when viewed from a specific direction, for example, one of them. This includes moving one upward and the other upward as well.

Includes moving upwards and the other downwards.

(各実施の形態の共通部−車輪)
車輪20は、接地対象面110に対して接地される接地部である。この車輪20の数は、各実施の形態では4つ(第一車輪21、第二車輪22、第三車輪23、及び第四車輪24)であるが、少なくとも4つ以上である限り任意であり、例えば、6つや8つ等でも構わない。なお、第一車輪21は右前輪、第二車輪22は右後輪、第三車輪23は左前輪、第四車輪24は左後輪である。ここで、以下では車体70における前方に位置する車輪20(各実施の形態では、右前輪(第一車輪21)及び左前輪(第三車輪23))を「前輪」、後方に位置する車輪20(各実施の形態では、右後輪(第二車輪22)及び左後輪(第四車輪24))を「後輪」、右方に位置する車輪20(各実施の形態では、右前輪(第一車輪21)及び右後輪(第二車輪22))を「右輪」、左方に位置する車輪20(各実施の形態では、左前輪(第三車輪23)及び左後輪(第四車輪24))を「左輪」と称して説明する。
(Common part of each embodiment-wheel)
The wheel 20 is a ground contact portion that is grounded with respect to the ground contact surface 110. The number of the wheels 20 is four (first wheel 21, second wheel 22, third wheel 23, and fourth wheel 24) in each embodiment, but is arbitrary as long as it is at least four or more. For example, 6 or 8 may be used. The first wheel 21 is the right front wheel, the second wheel 22 is the right rear wheel, the third wheel 23 is the left front wheel, and the fourth wheel 24 is the left rear wheel. Here, in the following, the front wheels 20 (in each embodiment, the right front wheel (first wheel 21) and the left front wheel (third wheel 23)) of the vehicle body 70 are referred to as "front wheels", and the wheels 20 located rearward. (In each embodiment, the right rear wheel (second wheel 22) and the left rear wheel (fourth wheel 24)) are referred to as the "rear wheel", and the wheel 20 located to the right (in each embodiment, the right front wheel (in each embodiment). The first wheel 21) and the right rear wheel (second wheel 22) are referred to as the "right wheel", and the wheel 20 located to the left (in each embodiment, the left front wheel (third wheel 23) and the left rear wheel (first wheel)). The four wheels 24)) will be described with reference to the "left wheel".

また、各車輪20はそれぞれ対応する旋回機構30の先端に対して接続されている。なお、これらの各車輪20はそれぞれ図示しない駆動用モータに接続されており、駆動用モータを回転させて各車輪20を回転させることにより、車両10が前後に走行できる。なお、このように車輪20を回転させて走行させるための機構については公知であるため、図示及び詳細な説明を省略する。 Further, each wheel 20 is connected to the tip of the corresponding turning mechanism 30. Each of these wheels 20 is connected to a drive motor (not shown), and the vehicle 10 can travel back and forth by rotating the drive motor to rotate each wheel 20. Since the mechanism for rotating and traveling the wheel 20 in this way is known, illustration and detailed description thereof will be omitted.

(各実施の形態の共通部−旋回機構)
旋回機構30は、車輪20に接続されており、上下移動動作(後述する)を行うことによって当該接続された車輪20に対する車体70の位置を上下に移動させる上下移動機構である。この旋回機構30の数は、各実施の形態では車輪20と対応する数であり4つ(第一旋回機構31、第二旋回機構32、第三旋回機構33、及び第四旋回機構34)であるが、これに限らず、車輪20と対応しない数でもよく、具体的には一つの旋回機構30に対して二つ以上の車輪20を接続しても構わない。なお、単一の旋回機構30と上述した単一の車輪20とのセットを必要に応じて「脚」と称して説明する。
(Common part of each embodiment-swivel mechanism)
The turning mechanism 30 is a vertical movement mechanism that is connected to the wheels 20 and moves the position of the vehicle body 70 with respect to the connected wheels 20 up and down by performing a vertical movement operation (described later). The number of the swivel mechanism 30 is the number corresponding to the wheel 20 in each embodiment, and is four (first swivel mechanism 31, second swivel mechanism 32, third swivel mechanism 33, and fourth swivel mechanism 34). However, the number is not limited to this, and the number may not correspond to the wheels 20, and specifically, two or more wheels 20 may be connected to one turning mechanism 30. A set of the single turning mechanism 30 and the single wheel 20 described above will be referred to as “legs” as necessary.

ここで、「上下移動動作」とは、旋回軸40の旋回動作を受けて車輪20を上下に移動させる動作であり、各実施の形態の上下移動動作は、旋回軸40と直交する平面上(各実施の形態ではY−Z平面上)を、旋回機構30が旋回軸40を中心として時計回り又は反時計回りに旋回する動作である。なお、図1や図2に示すように、各実施の形態では、前方の2つの旋回機構30(第一旋回機構31及び第三旋回機構33)と、後方の2つの旋回機構30(第二旋回機構32及び第四旋回機構34)とは前後対称に形成されている。そのため、前方の旋回機構30と後方の旋回機構30とは、旋回方向と車輪20の上下動の方向との対応関係が相互に異なる。具体的には、前方の2つの旋回機構30が、旋回軸40を中心として左方向(−X方向)から見て時計回りに旋回した際には前輪は上昇し、左方向(−X方向)から見て反時計回りに旋回した際には前輪は下降する。一方、後方の2つの旋回機構30が旋回軸40を中心として左方向(−X方向)から見て時計回りに旋回した際には後輪は下降し、左方向(−X方向)から見て反時計回りに旋回した際には後輪は上昇する。 Here, the "vertical movement operation" is an operation of moving the wheel 20 up and down in response to the turning operation of the turning shaft 40, and the vertical moving operation of each embodiment is on a plane orthogonal to the turning shaft 40 ( In each embodiment, the swivel mechanism 30 swivels clockwise or counterclockwise around the swivel shaft 40) on the YY plane. As shown in FIGS. 1 and 2, in each embodiment, two front swivel mechanisms 30 (first swivel mechanism 31 and third swivel mechanism 33) and two rear swivel mechanisms 30 (second swivel mechanism 30). The swivel mechanism 32 and the fourth swivel mechanism 34) are formed symmetrically in the front-rear direction. Therefore, the front turning mechanism 30 and the rear turning mechanism 30 have different correspondence relationships between the turning direction and the vertical movement direction of the wheels 20. Specifically, when the two front turning mechanisms 30 turn clockwise when viewed from the left direction (-X direction) about the turning shaft 40, the front wheels rise and the left direction (-X direction). When viewed counterclockwise, the front wheels descend. On the other hand, when the two rear turning mechanisms 30 turn clockwise when viewed from the left direction (-X direction) about the turning shaft 40, the rear wheels descend and are viewed from the left direction (-X direction). The rear wheels rise when turning counterclockwise.

ここで、車輪20の位置が上昇した場合には、相対的に車体70から車輪20までの高さ方向の距離が小さくなるので、当該車輪20の位置における車高(接地対象面110から車体70までの高さ方向の距離)は低くなる。一方、車輪20の位置が下降した場合には、相対的に車体70から車輪20までの高さ方向の距離が大きくなるので、当該車輪20の位置における車高は高くなる。 Here, when the position of the wheel 20 rises, the distance in the height direction from the vehicle body 70 to the wheel 20 becomes relatively small, so that the vehicle height at the position of the wheel 20 (from the ground contact target surface 110 to the vehicle body 70) Distance in the height direction to) becomes lower. On the other hand, when the position of the wheel 20 is lowered, the distance from the vehicle body 70 to the wheel 20 in the height direction becomes relatively large, so that the vehicle height at the position of the wheel 20 becomes high.

(各実施の形態の共通部−旋回軸)
旋回軸40は、旋回動作を行うことによって、旋回機構30に上下移動動作を行わせる軸である。この旋回軸40の数は、各実施の形態では旋回機構30と対応する数であり4つ(第一旋回軸41、第二旋回軸42、第三旋回軸43、及び第四旋回軸44)であるが、これに限らず、旋回機構30と対応しない数でもよく、具体的には一つの旋回軸40に対して二つ以上の旋回機構30を接続したり、複数の旋回軸40に対して1つ旋回機構30を接続したりしても構わない。
(Common part of each embodiment-swivel shaft)
The swivel shaft 40 is a shaft that causes the swivel mechanism 30 to perform a vertical movement operation by performing a swivel operation. The number of the swivel shafts 40 is a number corresponding to the swivel mechanism 30 in each embodiment, and is four (first swivel shaft 41, second swivel shaft 42, third swivel shaft 43, and fourth swivel shaft 44). However, the number is not limited to this, and the number may not correspond to the swivel mechanism 30. Specifically, two or more swivel mechanisms 30 may be connected to one swivel shaft 40, or a plurality of swivel shafts 40 may be connected. One swivel mechanism 30 may be connected.

ここで、「旋回動作」とは、旋回軸40の軸方向を中心として旋回軸40に直交する平面上を時計回り又は反時計回りに旋回軸40が旋回する動作である。このように旋回軸40が旋回動作を行うことにより、旋回軸40に接続された旋回機構30が旋回軸40を中心として旋回して、旋回機構30における旋回軸40が接続された側と反対側の端部に接続された車輪20が上下に移動する。 Here, the "swivel operation" is an operation in which the swivel shaft 40 swivels clockwise or counterclockwise on a plane orthogonal to the swivel shaft 40 about the axial direction of the swivel shaft 40. When the swivel shaft 40 performs the swivel operation in this way, the swivel mechanism 30 connected to the swivel shaft 40 swivels around the swivel shaft 40, and the side of the swivel mechanism 30 opposite to the side to which the swivel shaft 40 is connected. The wheel 20 connected to the end of the wheel 20 moves up and down.

(各実施の形態の共通部−連結軸)
連結軸50は、旋回軸40に接続されており、旋回軸40を旋回動作させる軸である。具体的には、共通部としては少なくとも第一連結軸51と第二連結軸52とを備える。ここで、第一連結軸51とは、第一旋回軸41に接続されており、第一旋回軸41を旋回動作させる軸である。第二連結軸52とは、第二旋回軸42に接続されており、第二旋回軸42を旋回動作させる軸である。ここで、「旋回軸40を旋回動作させる」とは、連結軸50が旋回することによって当該連結軸50から旋回軸40へと力が伝達して旋回軸40が旋回動作することである。具体的には、第一連結軸51と第一旋回軸41は、図1に示すように、相互に直交するように噛み合うギア10a及びギア10bを介して相互に接続されており、第一連結軸51が旋回すると、第一旋回軸41を旋回動作させることができる。また、第二連結軸52と第二旋回軸42は、相互に直交するように噛み合うギア10c及びギア10dを介して相互に接続されており、第二連結軸52が旋回すると、第二旋回軸42を旋回動作させることができる。なお、各実施の形態において各ギアとしては公知のかさ歯車を適用している。
(Common part of each embodiment-connecting shaft)
The connecting shaft 50 is connected to the swivel shaft 40 and is a shaft that swivels the swivel shaft 40. Specifically, as a common portion, at least a first connecting shaft 51 and a second connecting shaft 52 are provided. Here, the first connecting shaft 51 is a shaft that is connected to the first swivel shaft 41 and that swivels the first swivel shaft 41. The second connecting shaft 52 is a shaft that is connected to the second swivel shaft 42 and causes the second swivel shaft 42 to swivel. Here, "to swivel the swivel shaft 40" means that when the connecting shaft 50 swivels, a force is transmitted from the connecting shaft 50 to the swivel shaft 40 and the swivel shaft 40 swivels.

(Common part-control part of each embodiment)

Specifically, the CPU, various programs interpreted and executed on the CPU (basic control programs such as the OS, and specific functions activated on the OS) are performed. It is a computer configured with an internal memory such as a RAM (including an application program to be realized) and a RAM for storing the program and various data.

I do. The details of the specific processing executed by the control unit 100 will be described later.

(共通部の機能)
次に、共通部の機能について説明する。上記の共通部の構成によれば、各車輪20はそれぞれ連動しており、いずれかの車輪20が上又は下に動いた際には、他の全ての車輪20が連動して上又は下方向に動くように構成されている。具体的には、図1の矢印で示すように、図1の平面視における対角線上の一対の車輪20が相互に同一方向に動くようになっており、例えば、第一車輪21が段差等に乗り上げて上昇した場合、第一旋回機構31が左方(−X方向)から見て時計回りに旋回して第一旋回軸41も左方から見て時計回りに旋回する。ここで、第一旋回軸41の旋回力は第一反転機構61で反転されて第三旋回軸43に伝わるので、第三旋回軸43は左方から見て反時計回りに旋回し、このことにより第三車輪23は図示のように下降する。また、第一旋回軸41の旋回力はギア10b及びギア10aを介して第一連結軸51に伝わり、第一連結軸51を後方(−Y方向)から見て反時計回りに旋回させる。そして、第一連結軸51の旋回力は第三反転機構63で反転されて第二連結軸52を後方から見て時計回りに旋回させ、ギア10c及びギア10dを介して第二旋回軸42を左方から見て時計回りに旋回させる。したがって、第二車輪22は下降する。また、第二旋回軸42の旋回力は第二反転機構62で反転されて第四旋回軸44に伝わるので、第四旋回軸44は左方から見て反時計回りに旋回し、このことにより第四車輪24は図示のように上昇する。
(Functions of common parts)
Next, the functions of the common part will be described. According to the configuration of the common portion described above, each wheel 20 is interlocked, and when any wheel 20 moves up or down, all the other wheels 20 are interlocked in the upward or downward direction. It is configured to move to. Specifically, as shown by the arrow in FIG. 1, the pair of wheels 20 on the diagonal line in the plan view of FIG. 1 move in the same direction with each other. For example, the first wheel 21 is formed on a step or the like. When climbing up, the first turning mechanism 31 turns clockwise when viewed from the left (-X direction), and the first turning shaft 41 also turns clockwise when viewed from the left. Here, since the turning force of the first turning shaft 41 is reversed by the first reversing mechanism 61 and transmitted to the third turning shaft 43, the third turning shaft 43 turns counterclockwise when viewed from the left. As a result, the third wheel 23 descends as shown in the figure. Further, the turning force of the first turning shaft 41 is transmitted to the first connecting shaft 51 via the gear 10b and the gear 10a, and the first connecting shaft 51 is turned counterclockwise when viewed from the rear (−Y direction). Then, the turning force of the first connecting shaft 51 is reversed by the third reversing mechanism 63, the second connecting shaft 52 is swiveled clockwise when viewed from the rear, and the second swivel shaft 42 is swung via the gear 10c and the gear 10d. Turn clockwise when viewed from the left. Therefore, the second wheel 22 descends. Further, since the turning force of the second turning shaft 42 is reversed by the second reversing mechanism 62 and transmitted to the fourth turning shaft 44, the fourth turning shaft 44 turns counterclockwise when viewed from the left, which causes the fourth turning shaft 44 to turn counterclockwise. The fourth wheel 24 rises as shown.

したがって、共通部の構成によれば、車輪20の接地を確保することができる。すなわち、いずれかの車輪20が不整地の段差に乗り上げてしまった場合等には、複数の車輪20のうちいずれかが浮いてしまい車両10の安定性が損なわれてしまうことがあるが、共通部の構成によればこのような車輪20の浮きを解消でき、安定性を確保できる。例えば、第一車輪21が不整地の段差に乗り上げてしまった場合、第一車輪21、第三車輪23、及び第四車輪24が接地した状態で第二車輪22が浮いてしまうことがある(三点接地)。この場合に、共通部の固有の機能のみを考慮すると、第二車輪22が自身の重みによって自動的に下降し、これに連動して第三車輪23が下降し、第一車輪21及び第四車輪24が上昇する。そして、第二車輪22が接地した場合に全ての車輪20の接地が完了し(四点接地)、各車輪20に荷重配分して車両10の安定性を高めることができる。 Therefore, according to the configuration of the common portion, it is possible to secure the ground contact of the wheel 20. That is, if any of the wheels 20 rides on a step on rough terrain, one of the plurality of wheels 20 may float and the stability of the vehicle 10 may be impaired. According to the configuration of the portion, such floating of the wheel 20 can be eliminated, and stability can be ensured. For example, when the first wheel 21 rides on a step on rough terrain, the second wheel 22 may float while the first wheel 21, the third wheel 23, and the fourth wheel 24 are in contact with the ground (. Three-point grounding). In this case, considering only the unique function of the common part, the second wheel 22 is automatically lowered by its own weight, and the third wheel 23 is lowered in conjunction with this, and the first wheel 21 and the fourth wheel are fourth. The wheel 24 rises. Then, when the second wheel 22 touches the ground, the touching of all the wheels 20 is completed (four-point touching), and the load can be distributed to each wheel 20 to improve the stability of the vehicle 10.

このように、共通部の構成によれば四点接地による荷重配分の機能を実現することが可能であるが、さらに下記の固有部を設けることにより、当該共通部の機能を維持しつつ、後述する固有部の機能(例えば、左右方向に関する姿勢制御、前後方向に関する姿勢制御、又は車高調整等)を実現することが可能となる。 In this way, according to the configuration of the common part, it is possible to realize the function of load distribution by four-point grounding, but by further providing the following unique part, the function of the common part is maintained and described later. It is possible to realize the function of the unique portion (for example, attitude control in the left-right direction, attitude control in the front-rear direction, vehicle height adjustment, etc.).

(実施の形態1)
次に、実施の形態1について説明する。ここで、実施の形態1に係る制御機構は、概略的に、左右方向の傾斜を調整する制御機構である。
(Embodiment 1)
Next, the first embodiment will be described. Here, the control mechanism according to the first embodiment is a control mechanism that roughly adjusts the inclination in the left-right direction.

(実施の形態1の固有部)
この実施の形態1に係る車両10は、上述した共通部に加えて、本実施の形態1に固有の構成(以下、固有部)を有している。図3は、本実施の形態1の車両10の共通部及び固有部を模式的に示す平面図である。この図3に示すように、本実施の形態1の固有部として、第三反転機構63が差動装置として構成されており、第三反転機構モータ120を備えている。なお、以下の各図では、差動装置を一点鎖線で囲っている。
(Specific part of Embodiment 1)
The vehicle 10 according to the first embodiment has a configuration (hereinafter, a unique portion) peculiar to the first embodiment in addition to the common portion described above. FIG. 3 is a plan view schematically showing a common portion and a unique portion of the vehicle 10 of the first embodiment. As shown in FIG. 3, as a unique portion of the first embodiment, the third reversing mechanism 63 is configured as a differential device and includes a third reversing mechanism motor 120. In each of the following figures, the differential device is surrounded by a alternate long and short dash line.

(実施の形態1の固有部−第三反転機構)
図3に示すように、第三反転機構63は差動装置として構成されており、当該差動装置に接続された第一連結軸51及び第二連結軸52は、相互に同一方向と反対方向とに選択的に旋回可能となっている。ここで、「同一方向に旋回可能」とは、以下では、枠体10gは車体70に対して固定されておらず第一連結軸51及び第二連結軸52を中心として旋回可能となっており、図3の矢印に示すように、第三反転機構モータ120が稼働した際に、第三反転機構モータ120に取り付けられたギア10jが旋回し、これを受けてギア10jに対して直交に噛み合うギア10iを介して枠体10gが旋回すると、枠体10gに固定されたギア10hが枠体10gと共に第一連結軸51及び第二連結軸52を中心として旋回し、当該ギア10hを介してギア10e及びギア10fに力が伝達することによって、枠体10g、ギア10e、及びギア10fがX−Z平面に沿って相互に同一方向に旋回することを示す。一方、「反対方向に旋回可能」とは、以下では、第一連結軸51と第二連結軸52が相互に反対方向に旋回することによりギア10e及びギア10fが相互に反対方向に旋回した場合でも、枠体10gは旋回せずに、ギア10hが枠体10gに対して旋回状態となりギア10e及びギア10fの差動を許容できることを示す。なお、このような差動装置の構成は公知であるため、詳細な説明を省略する。また、枠体10gの側方には枠体10gと一体に旋回可能なギア10iが固定されており、第三反転機構モータ120からの動力が当該ギア10iを介して枠体10gに伝達される。
(Inherent part of Embodiment 1-Third reversing mechanism)
As shown in FIG. 3, the third reversing mechanism 63 is configured as a differential device, and the first connecting shaft 51 and the second connecting shaft 52 connected to the differential device are in the same direction and opposite directions to each other. It is possible to selectively turn. Here, "swivelable in the same direction" means that, in the following, the frame body 10g is not fixed to the vehicle body 70 and can be swiveled around the first connecting shaft 51 and the second connecting shaft 52. As shown by the arrow in FIG. 3, when the third reversing mechanism motor 120 is operated, the gear 10j attached to the third reversing mechanism motor 120 turns, and in response to this, meshes orthogonally with the gear 10j. When the frame body 10g turns via the gear 10i, the gear 10h fixed to the frame body 10g turns around the first connecting shaft 51 and the second connecting shaft 52 together with the frame body 10g, and the gears pass through the gear 10h. It is shown that the frame body 10g, the gear 10e, and the gear 10f turn in the same direction with each other along the XZ plane by transmitting the force to the 10e and the gear 10f. On the other hand, "can turn in the opposite direction" means that the gear 10e and the gear 10f turn in opposite directions when the first connecting shaft 51 and the second connecting shaft 52 turn in opposite directions. However, the frame body 10g does not turn, and the gear 10h is in a turning state with respect to the frame body 10g, indicating that the differential between the gear 10e and the gear 10f can be tolerated. Since the configuration of such a differential device is known, detailed description thereof will be omitted. Further, a gear 10i that can rotate integrally with the frame body 10g is fixed to the side of the frame body 10g, and the power from the third reversing mechanism motor 120 is transmitted to the frame body 10g via the gear 10i. ..

(実施の形態1の固有部−第三反転機構モータ)
第三反転機構モータ120は、差動装置として構成された第三反転機構63を旋回させる第三反転機構動力手段であって、差動装置に接続された第一連結軸51及び第二連結軸52を相互に同一方向に旋回させることにより、第一車輪21及び第二車輪22に対する車体70の位置と、第三車輪23及び第四車輪24に対する車体70の位置とが相互に上下反対方向に移動するように、各旋回軸40を旋回させる第三反転機構動力手段である。なお、この第三反転機構モータ120には、第三反転機構モータ120の停止時に空回転してしまわないように公知のブレーキ機構が設けられていることが好ましい。
(Inherent part of Embodiment 1-Third reversing mechanism motor)
The third reversing mechanism motor 120 is a third reversing mechanism power means for turning the third reversing mechanism 63 configured as a differential device, and is a first connecting shaft 51 and a second connecting shaft connected to the differential device. By turning the 52 in the same direction, the position of the vehicle body 70 with respect to the first wheel 21 and the second wheel 22 and the position of the vehicle body 70 with respect to the third wheel 23 and the fourth wheel 24 are opposite to each other. It is a third reversing mechanism power means that swivels each swivel shaft 40 so as to move. It is preferable that the third reversing mechanism motor 120 is provided with a known brake mechanism so as not to idlely rotate when the third reversing mechanism motor 120 is stopped.

(固有部の機能)
次に、固有部の機能について説明する。上記の固有部の構成によれば、図3に矢印で示すように、第三反転機構モータ120を作動させることにより、第一連結軸51と第二連結軸52とを相互に同一方向に旋回させることができ、右輪(第一車輪21及び第二車輪22)と左輪(第三車輪23及び第四車輪24)とを相互に反対方向に上下動させることができる。例えば右輪を上昇させた場合は左輪が下降し、逆に、右輪を下降させた場合は左輪が上昇する。したがって、車両10が走行中に車体70が傾いてしまった時であっても、第三反転機構モータ120を作動させることで、右輪又は左輪のうちいずれか一方を上昇させ、いずれか他方を下降させることで、車体70の左右の傾斜を解消することが可能である。
(Function of unique part)
Next, the function of the unique part will be described. According to the configuration of the specific portion described above, as shown by the arrow in FIG. 3, the first connecting shaft 51 and the second connecting shaft 52 are swiveled in the same direction by operating the third reversing mechanism motor 120. The right wheel (first wheel 21 and second wheel 22) and the left wheel (third wheel 23 and fourth wheel 24) can be moved up and down in opposite directions. For example, when the right wheel is raised, the left wheel is lowered, and conversely, when the right wheel is lowered, the left wheel is raised. Therefore, even when the vehicle body 70 is tilted while the vehicle 10 is running, by operating the third revolver motor 120, either the right wheel or the left wheel is raised, and the other is raised. By lowering it, it is possible to eliminate the left-right inclination of the vehicle body 70.

(制御)
次に、本実施の形態1に係る制御部100にて実行される制御の内容の一例について説明する。
(control)
Next, an example of the content of the control executed by the control unit 100 according to the first embodiment will be described.

まず、共通部の機能により、制御部100にて何ら制御を行うことなく、各車輪20に対する加重配分が行われる。すなわち、いずれかの車輪20が不整地の段差に乗り上げて他の車輪20が浮いてしまった場合であっても、上述したように当該他の車輪20は共通部の機構により下降して接地するので、四点支持により車両10の安定性を高めることができる。 First, due to the function of the common unit, the weight is distributed to each wheel 20 without any control by the control unit 100. That is, even if one of the wheels 20 rides on a step on rough terrain and the other wheel 20 floats, the other wheel 20 descends and touches down by the mechanism of the common portion as described above. Therefore, the stability of the vehicle 10 can be improved by supporting the four points.

ここで、傾斜計90は所定の時刻間隔(例えば1秒間隔)で車体70の傾斜に関する情報(例えば傾斜角度)を制御部100に送信する。次に、制御部100は、受信した傾斜角度が、予め車両10のデータ記録部(図示省略)に格納された閾値(任意に設定可能。例えば、5度)を超えたか否かを判定し、超えた場合には、第三反転機構モータ120を作動させて右輪と左輪の高さを調整することにより、傾斜角度が適正値(任意に設定可能。例えば、1度)未満となるように制御する。このことにより、左右の傾斜が調整され、車両10の安定性を向上させることができる。 Here, the inclinometer 90 transmits information regarding the inclination of the vehicle body 70 (for example, an inclination angle) to the control unit 100 at a predetermined time interval (for example, an interval of 1 second). Next, the control unit 100 determines whether or not the received inclination angle exceeds the threshold value (arbitrarily settable, for example, 5 degrees) stored in the data recording unit (not shown) of the vehicle 10 in advance. If it exceeds, the third reversing mechanism motor 120 is operated to adjust the heights of the right wheel and the left wheel so that the inclination angle becomes less than an appropriate value (arbitrarily settable, for example, 1 degree). Control. As a result, the left and right inclinations can be adjusted, and the stability of the vehicle 10 can be improved.

すなわち、本実施の形態1の車両10によれば、共通部による荷重配分の機能を維持しつつ、固有部によって、車体70に生じた左右方向の傾斜を解消する姿勢制御の機能を実現することが可能となる。 That is, according to the vehicle 10 of the first embodiment, the function of attitude control that eliminates the left-right inclination caused in the vehicle body 70 by the unique portion is realized while maintaining the function of load distribution by the common portion. Is possible.

(実施の形態1の効果)
このような本実施の形態1に係る制御機構1によれば、第一反転機構61、第二反転機構62、及び第三反転機構63を備えることにより、第一車輪21と第四車輪24のセット、及び第二車輪22と第三車輪23のセットを相互に上下反対方向に連動させて荷重配分できると共に、第三反転機構63を差動装置として構成し、第三反転機構モータ120によって、第一車輪21及び第二車輪22に対する車体70の位置と、第三車輪23及び第四車輪24に対する車体70の位置とが相互に上下反対方向に移動するように各旋回軸40を旋回させるので、第一車輪21及び第二車輪22側から第三車輪23及び第四車輪24側へと至るように車体70を傾けて姿勢制御することができるので、バネ、ワイヤ、又は流体式サスペンション等の複雑な機構を省略した極めて簡素な機構な機構により荷重配分及び姿勢制御ができ、コストの削減や利用性の向上が可能となる。
(Effect of Embodiment 1)
According to the control mechanism 1 according to the first embodiment, the first wheel 21 and the fourth wheel 24 are provided with the first reversing mechanism 61, the second reversing mechanism 62, and the third reversing mechanism 63. The set and the set of the second wheel 22 and the third wheel 23 can be interlocked with each other in the opposite directions to distribute the load, and the third reversing mechanism 63 is configured as a differential device by the third reversing mechanism motor 120. Since each turning shaft 40 is turned so that the position of the vehicle body 70 with respect to the first wheel 21 and the second wheel 22 and the position of the vehicle body 70 with respect to the third wheel 23 and the fourth wheel 24 move in opposite directions to each other. Since the vehicle body 70 can be tilted to control the posture from the first wheel 21 and the second wheel 22 side to the third wheel 23 and the fourth wheel 24 side, a spring, a wire, a fluid suspension, or the like can be used. Load distribution and attitude control can be performed by an extremely simple mechanism that omits a complicated mechanism, which makes it possible to reduce costs and improve usability.

It is possible to selectively turn. Since the configuration of the differential device is the same as that of the third reversing mechanism 63 of the first embodiment, detailed description thereof will be omitted. Further, a gear 10l that can rotate integrally with the frame body 10q is fixed to the side of the frame body 10q of the second reversing mechanism 62, and the power from the first and second reversing mechanism motor 130 passes through the gear 10l.

(Inherent part of Embodiment 2-Third connecting shaft)
The third connecting shaft 53 is a shaft that connects the first reversing mechanism 61 and the second reversing mechanism 62 configured as a differential device to each other. Here, specifically, a gear 10o that rotates integrally with the third connecting shaft 53 is provided at a substantially intermediate portion in the front-rear direction (Y direction) of the third connecting shaft 53, and is provided with a first and second reversing mechanism.

Is provided with a gear 10n that is meshed with the gear 10l at right angles to each other.

(実施の形態2の固有部−第一第二反転機構モータ)
第一第二反転機構モータ130は、第三連結軸53を旋回させる第一第二反転機構動力手段であって、第三連結軸53に接続された2つの差動装置(第一反転機構61及び第二反転機構62)を旋回させることにより、第一車輪21及び第三車輪23に対する車体70の位置と、第二車輪22及び第四車輪24に対する車体70の位置とが相互に上下反対方向に移動するように、各旋回軸40を旋回させる第一第二反転機構動力手段である。
(Inherent part of the second embodiment-first and second reversing mechanism motor)
The first and second reversing mechanism motor 130 is a first and second reversing mechanism power means for turning the third connecting shaft 53, and is two differential devices (first reversing mechanism 61) connected to the third connecting shaft 53. And by turning the second reversing mechanism 62), the position of the vehicle body 70 with respect to the first wheel 21 and the third wheel 23 and the position of the vehicle body 70 with respect to the second wheel 22 and the fourth wheel 24 are in opposite directions. It is a first and second reversing mechanism power means that swivels each swivel shaft 40 so as to move to.

ここで、第一第二反転機構モータ130にはギア10rが取り付けられており、このギア10rはギア10oに対して相互に直交に噛み合わされている。したがって、第一第二反転機構モータ130を作動させると、ギア10r及びギア10oを介して第三連結軸53が旋回する。このことにより、ギア10m及びギア10kを介して枠体10pが第一旋回軸41及び第三旋回軸43を中心として旋回し、第一旋回軸41及び第三旋回軸43が相互に同一方向に旋回する(図4の矢印参照)と共に、ギア10n及びギア10lを介して枠体10qが第二旋回軸42及び第四旋回軸44を中心として旋回し、第二旋回軸42及び第四旋回軸44が相互に同一方向に旋回する(図4の矢印参照)。 Here, a gear 10r is attached to the first and second reversing mechanism motor 130, and the gear 10r is meshed with the gear 10o at right angles to each other. Therefore, when the first and second reversing mechanism motor 130 is operated, the third connecting shaft 53 rotates via the gear 10r and the gear 10o. As a result, the frame body 10p swivels around the first swivel shaft 41 and the third swivel shaft 43 via the gear 10m and the gear 10k, and the first swivel shaft 41 and the third swivel shaft 43 rotate in the same direction. Along with turning (see the arrow in FIG. 4), the frame body 10q turns around the second turning shaft 42 and the fourth turning shaft 44 via the gear 10n and the gear 10l, and the second turning shaft 42 and the fourth turning shaft 42. The 44s turn in the same direction with each other (see the arrow in FIG. 4).

(固有部の機能)
次に、固有部の機能について説明する。上記の固有部の構成によれば、図4に矢印で示すように、第一第二反転機構モータ130を作動させることにより、第一旋回軸41と第三旋回軸43とを相互に同一方向に旋回させることができると共に、第二旋回軸42と第四旋回軸44とを相互に同一方向に旋回させることができ、前輪(第一車輪21及び第三車輪23)と後輪(第二車輪22及び第四車輪24)とを相互に反対方向に上下動させることができる。例えば、前輪を上昇させた場合は後輪が下降し、逆に、前輪を下降させた場合は後輪が上昇する。したがって、車両10が走行中に車体70が傾いてしまった時であっても、第一第二反転機構モータ130を作動させることで、前輪又は後輪のうちいずれか一方を上昇させ、いずれか他方を下降させることで、車体70の前後の傾斜を解消することが可能である。
(Function of unique part)
Next, the function of the unique part will be described. According to the configuration of the specific portion described above, as shown by the arrow in FIG. 4, the first swivel shaft 41 and the third swivel shaft 43 are oriented in the same direction by operating the first and second reversing mechanism motor 130. The second turning shaft 42 and the fourth turning shaft 44 can be turned in the same direction with each other, and the front wheels (first wheel 21 and third wheel 23) and the rear wheel (second wheel) can be turned. The wheels 22 and the fourth wheel 24) can be moved up and down in opposite directions. For example, when the front wheels are raised, the rear wheels are lowered, and conversely, when the front wheels are lowered, the rear wheels are raised. Therefore, even when the vehicle body 70 is tilted while the vehicle 10 is running, by operating the first and second reversing mechanism motors 130, either the front wheels or the rear wheels are raised, and either of them is raised. By lowering the other, it is possible to eliminate the front-rear inclination of the vehicle body 70.

次に、本実施の形態2に係る制御部100にて実行される制御の内容の一例について説明する。まず、共通部の機能により、制御部100にて何ら制御を行うことなく、車輪20の浮きは自動的に解消される。
(control)
Next, an example of the content of the control executed by the control unit 100 according to the second embodiment will be described. First, due to the function of the common unit, the floating of the wheel 20 is automatically eliminated without any control by the control unit 100.

ここで、傾斜計90は所定の時刻間隔(例えば1秒間隔)で車体70の傾斜に関する情報(例えば傾斜角度)を制御部100に送信する。次に、制御部100は、受信した傾斜角度が、予め車両10のデータ記録部(図示省略)に格納された閾値(任意に設定可能。例えば、5度)を超えたか否かを判定し、超えた場合には、第一第二反転機構モータ130を作動させて前輪と後輪の高さを調整することにより、傾斜角度が適正値(任意に設定可能。例えば、1度)未満となるように制御する。このことにより、前後の傾斜が調整され、車両10の安定性を向上させることができる。 Here, the inclinometer 90 transmits information regarding the inclination of the vehicle body 70 (for example, an inclination angle) to the control unit 100 at a predetermined time interval (for example, an interval of 1 second). Next, the control unit 100 determines whether or not the received inclination angle exceeds the threshold value (arbitrarily settable, for example, 5 degrees) stored in the data recording unit (not shown) of the vehicle 10 in advance. If it exceeds, the inclination angle becomes less than an appropriate value (can be set arbitrarily, for example, 1 degree) by operating the first and second reversing mechanism motors 130 to adjust the heights of the front wheels and the rear wheels. To control. As a result, the front-rear inclination is adjusted, and the stability of the vehicle 10 can be improved.

すなわち、本実施の形態2の車両10によれば、共通部による荷重配分の機能を維持しつつ、固有部によって、車体70に生じた前後方向の傾斜を解消する姿勢制御の機能を実現することが可能となる。 That is, according to the vehicle 10 of the second embodiment, the function of attitude control that eliminates the tilt in the front-rear direction caused by the vehicle body 70 is realized by the unique portion while maintaining the function of load distribution by the common portion.

(Inherent part of Embodiment 4)
FIG. 6 is a plan view schematically showing the vehicle 10 of the fourth embodiment. As shown in FIG. 6, in the vehicle 10 of the fourth embodiment, the first reversing mechanism 61, the second reversing mechanism 62, and the third reversing mechanism 63 are configured as differential devices, and the first reversing mechanism It includes a motor 140, a second reversing mechanism motor 150, and a third reversing mechanism motor 120. Since the third reversing mechanism motor 120 can be configured in the same manner as in the first embodiment, the configurations of the first reversing mechanism motor 140 and the second reversing mechanism motor 150 will be described below.

(実施の形態4の固有部−第一反転機構モータ)
第一反転機構モータ140は、差動装置として構成された第一反転機構61を旋回させる第一反転機構動力手段である。この第一反転機構モータ140にはギア10sが取り付けられており、このギア10sはギア10kに対して相互に直交に噛み合わされている。このことにより、第一反転機構モータ140を作動させると、枠体10pの全体がX軸を中心として旋回し、これにより第一旋回軸41及び第三旋回軸43が相互に同一方向に旋回する。
(Inherent part of Embodiment 4-First reversing mechanism motor)
The first reversing mechanism motor 140 is a first reversing mechanism power means for turning the first reversing mechanism 61 configured as a differential device. A gear 10s is attached to the first reversing mechanism motor 140, and the gear 10s is meshed with the gear 10k at right angles to each other. As a result, when the first reversing mechanism motor 140 is operated, the entire frame body 10p turns around the X axis, whereby the first turning shaft 41 and the third turning shaft 43 turn in the same direction. ..

(実施の形態4の固有部−第二反転機構モータ)
第二反転機構モータ150は、差動装置として構成された第二反転機構62を旋回させる第二反転機構動力手段である。この第二反転機構モータ150にはギア10tが取り付けられており、このギア10tはギア10lに対して相互に直交に噛み合わされている。このことにより、第一反転機構モータ140を作動させると、枠体10qの全体がX軸を中心として旋回し、これにより第二旋回軸42及び第四旋回軸44が相互に同一方向に旋回する。
(Inherent part of Embodiment 4-Second reversing mechanism motor)
The second reversing mechanism motor 150 is a second reversing mechanism power means for turning the second reversing mechanism 62 configured as a differential device. A gear 10t is attached to the second reversing mechanism motor 150, and the gear 10t is meshed with the gear 10l at right angles to each other. As a result, when the first reversing mechanism motor 140 is operated, the entire frame body 10q is swiveled around the X axis, whereby the second swivel shaft 42 and the fourth swivel shaft 44 are swiveled in the same direction. ..

(固有部の機能)
次に、固有部の機能について説明する。上記の固有部の構成によれば、前後左右両方向の傾斜を調整できると共に、車高を調整することができる。まず傾斜調整について説明すると、本実施の形態4の固有部は、実施の形態3の固有部同様に、第一反転機構61、第二反転機構62、及び第三反転機構63が差動装置として構成されているので、各差動装置を実施の形態3と同様に旋回させることができる。すなわち、左右の傾斜調整をする際には、第三反転機構モータ120を作動させることにより、図3に示す矢印のように各車輪20を昇降させることができ、前後の傾斜調整をする際には、第一反転機構モータ140及び第二反転機構モータ150を作動させて、ギア10sとギア10tとを相互に同一方向(例えば、後方(−Y方向)から見て時計回り)に旋回させることにより、図4に示す矢印のように各車輪20を昇降させることができる。
(Function of unique part)
Next, the function of the unique part will be described. According to the above-mentioned configuration of the unique portion, the inclination in both the front-rear, front-rear, left-right directions can be adjusted, and the vehicle height can be adjusted. First, the inclination adjustment will be described. In the specific portion of the fourth embodiment, the first reversing mechanism 61, the second reversing mechanism 62, and the third reversing mechanism 63 serve as a differential device, similarly to the intrinsic portion of the third embodiment. Since it is configured, each differential device can be swiveled in the same manner as in the third embodiment. That is, when adjusting the inclination to the left and right, by operating the third reversing mechanism motor 120, each wheel 20 can be raised and lowered as shown by the arrow shown in FIG. 3, and when adjusting the inclination to the front and back, Operates the first reversing mechanism motor 140 and the second reversing mechanism motor 150 to rotate the gear 10s and the gear 10t in the same direction (for example, clockwise when viewed from the rear (−Y direction)). As a result, each wheel 20 can be raised and lowered as shown by the arrow shown in FIG.

また、車高調整について説明すると、本実施の形態4では第一反転機構61と第二反転機構62とが図5に示す実施の形態3のように直接接続されておらず、図6に示すようにそれぞれ別のモータで制御可能に構成されているので、ギア10sとギア10tとを一方向(例えば後方向(−Y方向))から見て相互に反対方向に旋回可能となっている。そこで、ギア10sとギア10tとが一方向から見て相互に反対方向に旋回するように第一反転機構モータ140及び第二反転機構モータ150を作動させ、さらに第三反転機構モータ120を作動させる(すなわち、全てのモータを作動させる)ことにより、各機構は図6の矢印に示すように旋回し、全ての車輪20を一方向から見て相互に同一方向に移動させることができる。なお、図6では全ての車輪20を下降させる場合を図示しているが、ギア10sとギア10tを図示と反対方向に旋回させることで、全ての車輪20を上昇させることも可能である。 Further, to explain the vehicle height adjustment, in the fourth embodiment, the first reversing mechanism 61 and the second reversing mechanism 62 are not directly connected as in the third embodiment shown in FIG. 5, and are shown in FIG. As described above, the gears 10s and the gears 10t can be turned in opposite directions when viewed from one direction (for example, the rear direction (−Y direction)) because they are configured to be controllable by different motors. Therefore, the first reversing mechanism motor 140 and the second reversing mechanism motor 150 are operated so that the gear 10s and the gear 10t turn in opposite directions when viewed from one direction, and further, the third reversing mechanism motor 120 is operated. (That is, by operating all the motors), each mechanism can rotate as shown by the arrow in FIG. 6 and move all the wheels 20 in the same direction with each other when viewed from one direction. Although FIG. 6 shows a case where all the wheels 20 are lowered, it is also possible to raise all the wheels 20 by turning the gear 10s and the gear 10t in the opposite directions to those shown in the drawing.

なお、第一反転機構モータ140及び第二反転機構モータ150だけでなく第三反転機構モータ120も作動させる理由は、第一反転機構モータ140及び第二反転機構モータ150を作動させると、第一連結軸51及び第二連結軸52が同一方向に旋回して、枠体10g及びギア10iもこれらの連結軸50と同一方向に旋回しようとするので、この旋回に合せて第三反転機構モータ120を作動させる必要があるためである。 The reason why not only the first reversing mechanism motor 140 and the second reversing mechanism motor 150 but also the third reversing mechanism motor 120 are operated is that when the first reversing mechanism motor 140 and the second reversing mechanism motor 150 are operated, the first is Since the connecting shaft 51 and the second connecting shaft 52 turn in the same direction, and the frame body 10g and the gear 10i also try to turn in the same direction as these connecting shafts 50, the third reversing mechanism motor 120 is adapted to this turning. This is because it is necessary to operate.

Next, an example of the content of the control executed by the control unit 100 according to the fourth embodiment will be described. First, due to the function of the common unit, the floating of the wheel 20 is automatically eliminated without any control by the control unit 100.

ここで、傾斜計90は所定の時刻間隔(例えば1秒間隔)で車体70の傾斜に関する情報(例えば傾斜角度)を制御部100に送信する。また、車高検出用センサ80も所定の時刻間隔(例えば、傾斜計90と同様に1秒間隔)で車高に関する情報を制御部100に送信する。次に制御部100は、傾斜計90から受信した傾斜角度が予め車両10のデータ記録部(図示省略)に格納された閾値(任意に設定可能。例えば、5度)を超えたか否かを判定し、超えた場合には、第三反転機構モータ120を作動させて車輪20の高さを調整して左右方向の傾斜角度が適正値(任意に設定可能。例えば、1度)未満となるように制御すると共に、第一反転機構モータ140及び第二反転機構モータ150を作動させて車輪20の高さを調整して前後方向の傾斜角度が適正値(任意に設定可能。例えば、1度)未満となるように制御する。さらに、制御部100は、車高検出用センサ80から受信した車高が予め車両10のデータ記録部(図示省略)に格納された閾値(任意に設定可能。例えば10cm)以上であるか否かを判定し、閾値未満である場合、3つのモータ全てを同一回転量で作動させて車高を上げる。このような車高調整の目的は任意であるが、例えば、車高が低すぎて車体70が接地対象面110の段差や障害物に接触してしまう可能性がある場合に、接触を抑止する目的で行っても良い。なお、このような具体的な制御の内容は例示に過ぎず、例えば制御部100は、車高が高すぎる場合には車体70の安定性が損なわれてしまうものとし、3つのモータ全てを作動させて車高を下げても構わない。また、第一反転機構モータ140と第二反転機構モータ150とを相互に異なる回転量で、ギア10sとギア10tとが相互に同一方向に旋回するように回転させても構わない。この場合には、車高を調整しつつ、これら回転量の差に基づいて前後方向の傾きを調整できる。 Here, the inclinometer 90 transmits information regarding the inclination of the vehicle body 70 (for example, an inclination angle) to the control unit 100 at a predetermined time interval (for example, an interval of 1 second). Further, the vehicle height detection sensor 80 also transmits information on the vehicle height to the control unit 100 at predetermined time intervals (for example, 1 second intervals like the inclinometer 90). Next, the control unit 100 determines whether or not the inclination angle received from the inclinometer 90 exceeds the threshold value (arbitrarily settable, for example, 5 degrees) stored in the data recording unit (not shown) of the vehicle 10 in advance. If it exceeds the value, the third reversing mechanism motor 120 is operated to adjust the height of the wheel 20 so that the inclination angle in the left-right direction becomes less than an appropriate value (optionally set, for example, 1 degree). The first reversing mechanism motor 140 and the second reversing mechanism motor 150 are operated to adjust the height of the wheel 20 and the inclination angle in the front-rear direction can be set to an appropriate value (arbitrarily settable, for example, 1 degree). Control so that it is less than. Further, the control unit 100 determines whether or not the vehicle height received from the vehicle height detection sensor 80 is equal to or higher than a threshold value (arbitrarily settable, for example, 10 cm) stored in a data recording unit (not shown) of the vehicle 10 in advance. If it is less than the threshold value, all three motors are operated at the same rotation amount to raise the vehicle height. The purpose of such vehicle height adjustment is arbitrary, but for example, when the vehicle height is too low and the vehicle body 70 may come into contact with a step or an obstacle on the ground contact surface 110, contact is suppressed. You may go for the purpose. It should be noted that the specific content of such control is merely an example. For example, the control unit 100 operates all three motors assuming that the stability of the vehicle body 70 is impaired when the vehicle height is too high. You may let it lower the vehicle height. Further, the first reversing mechanism motor 140 and the second reversing mechanism motor 150 may be rotated at different rotation amounts so that the gear 10s and the gear 10t rotate in the same direction. In this case, the inclination in the front-rear direction can be adjusted based on the difference in the amount of rotation while adjusting the vehicle height.

すなわち、本実施の形態4の車両10によれば、共通部による荷重配分の機能を維持しつつ、固有部によって、車体70に生じた前後左右方向の傾斜を解消する姿勢制御の機能を実現すると共に、車高調整の機能を実現することが可能となる。 That is, according to the vehicle 10 of the fourth embodiment, the function of attitude control that eliminates the inclination in the front-rear and left-right directions caused by the vehicle body 70 is realized by the unique portion while maintaining the function of load distribution by the common portion. At the same time, it becomes possible to realize the function of adjusting the vehicle height.

(実施例)
続いて、本実施の形態4の実施例について説明する。図7は、本発明の実施例に係る表である。この実施例では、本実施の形態4に係る車両10の第一車輪21が段差に乗り上げてしまった際に、具体的にどのような制御を実行するかについて図7の表を参照しつつ簡略的に説明する。なお、上述したように、本実施の形態4は実施の形態1から実施の形態3の機能を含むものであるため、これらの各実施の形態についても同様に説明できるものとし、説明を省略する。
(Example)
Subsequently, an embodiment of the fourth embodiment will be described. FIG. 7 is a table according to an embodiment of the present invention. In this embodiment, what kind of control is specifically executed when the first wheel 21 of the vehicle 10 according to the fourth embodiment rides on a step is simplified with reference to the table of FIG. To explain. As described above, since the fourth embodiment includes the functions of the first to third embodiments, each of these embodiments can be described in the same manner, and the description thereof will be omitted.

ここで、以下では、図7に示すように、制御に関する一連の流れを、説明の便宜上、6つのフェーズに分けて説明する。ただし、各フェーズは時間的に区切られたものでなくても構わず、実際には複数のフェーズが同時に行われても良いし、各フェーズの順序も図示のものに限らない。また、項目「段差」、項目「脚の高さ」、項目「車高」に対応する情報は、それぞれの高さを二行二列の行列式で示したものであり、この行列式の各因子の配置は平面視における各車輪20の配置に対応する。例えば行列式の1行1列目の因子は第一車輪21、1行2列目の因子は第二車輪22、2行1列目の因子は第三車輪23、2行2列目の因子は第四車輪24に対応する。また、初期状態の脚の高さを「L」で表し、車両10が乗り上げる段差の高さを「x」で表し、必要な車高調整量を「H」で表している。 Here, as shown in FIG. 7, a series of flow related to control will be described by dividing it into six phases for convenience of explanation. However, each phase does not have to be separated in time, and in reality, a plurality of phases may be performed at the same time, and the order of each phase is not limited to the one shown in the figure. In addition, the information corresponding to the item "step", the item "leg height", and the item "vehicle height" shows each height by a determinant of two rows and two columns, and each of these determinants The arrangement of the factors corresponds to the arrangement of each wheel 20 in plan view. For example, the factor in the first row and first column of the determinant is the first wheel 21, the factor in the first row and second column is the second wheel 22, the factor in the second row and first column is the third wheel 23, and the factor in the second row and second column. Corresponds to the fourth wheel 24. Further, the height of the legs in the initial state is represented by "L", the height of the step on which the vehicle 10 rides is represented by "x", and the required vehicle height adjustment amount is represented by "H".

まず、フェーズ1は初期状態であって、車両10が水平面を走行している状態を示している。 First, Phase 1 is an initial state, and shows a state in which the vehicle 10 is traveling on a horizontal plane.

次に、フェーズ2すなわち第一車輪21が段差に乗り上げた場合には、第一車輪21及び第二車輪22は段差の高さxの分だけ車高が高くなるので、車高は「L+x」となる。なお、この際に第二車輪22は浮いた状態となる。 Next, in Phase 2, that is, when the first wheel 21 rides on a step, the height of the first wheel 21 and the second wheel 22 increases by the height x of the step, so that the vehicle height is "L + x". Will be. At this time, the second wheel 22 is in a floating state.

次に、フェーズ3すなわち共通部作動時には、上述した共通部の機能により第二車輪22と第三車輪23が下降するので、これらの車輪20の脚は伸びて高さが「L+x/4」となる。逆に、共通部の機能により第一車輪21と第四車輪24は上昇するので、これらの車輪20の脚は縮んで高さが「L−x/4」となる。このような共通部の機能によって、4点接地となり、車体70の安定性が向上する。なお、第二車輪22の位置の車高は、フェーズ2では「L+x」であるのに対し、フェーズ3では「L+x/4」となっており、第二車輪22の脚を伸ばしたにも関わらず車高が低くなっているが、これは、共通部により四輪が接地するように脚を伸縮することによって、車体70の第二車輪22側が下となるように傾いたことに起因するものである。 Next, in Phase 3, that is, when the common portion is operated, the second wheel 22 and the third wheel 23 are lowered by the function of the common portion described above, so that the legs of these wheels 20 are extended and the height is "L + x / 4". Become. On the contrary, since the first wheel 21 and the fourth wheel 24 are raised by the function of the common portion, the legs of these wheels 20 are contracted to have a height of "Lx / 4". Due to the function of such a common portion, four-point grounding is achieved, and the stability of the vehicle body 70 is improved. The vehicle height at the position of the second wheel 22 is "L + x" in Phase 2, whereas it is "L + x / 4" in Phase 3, even though the legs of the second wheel 22 are extended. The vehicle height is low, but this is due to the fact that the legs are expanded and contracted so that the four wheels touch the ground due to the common part, so that the second wheel 22 side of the vehicle body 70 is tilted downward. Is.

次に、フェーズ4すなわち第三反転機構モータ120作動時には、左右の傾きが調整される。具体的には、右輪側の脚の高さを「−x/4」して、左輪側の脚の高さを「+x/4」する。ここで、段差xの具体的な数値の求め方は任意であるが、例えば、車両10が段差に乗り上げた際(フェーズ2)における、車高検出用センサ80による検出結果(車体70中央の車高)と、傾斜計90による検出結果と、予め制御部100に格納された車両10の縦横の長さ等に基づいて、公知の計算方法で求めることができる。このことにより、フェーズ4の段階での車高は、第一車輪21の位置と第三車輪23の位置(前輪の位置)では「L+2/x」となり左右の車高が一致し、第二車輪22の位置と第四車輪24の位置(後輪の位置)では「L」となり左右の車高が一致する。このように、フェーズ4の段階では、第三反転機構モータ120を作動させることで左右の傾きを無くすことが可能である。 Next, when Phase 4, that is, when the third reversing mechanism motor 120 is operated, the left-right inclination is adjusted. Specifically, the height of the leg on the right wheel side is set to "-x / 4", and the height of the leg on the left wheel side is set to "+ x / 4". Here, the method of obtaining a specific numerical value of the step x is arbitrary. For example, when the vehicle 10 rides on the step (Phase 2), the detection result by the vehicle height detection sensor 80 (the vehicle in the center of the vehicle body 70). It can be obtained by a known calculation method based on the high), the detection result by the inclinometer 90, the vertical and horizontal lengths of the vehicle 10 stored in the control unit 100 in advance, and the like. As a result, the vehicle height at the stage of Phase 4 becomes "L + 2 / x" at the position of the first wheel 21 and the position of the third wheel 23 (position of the front wheel), and the left and right vehicle heights match, and the second wheel At the position of 22 and the position of the fourth wheel 24 (the position of the rear wheel), it becomes "L" and the left and right vehicle heights match. As described above, in the stage of the phase 4, it is possible to eliminate the left-right inclination by operating the third reversing mechanism motor 120.

次に、フェーズ5すなわち第一反転機構モータ140及び第二反転機構モータ150作動時には、ギア10sとギア10tとを相互に同一方向に旋回させることで、前後の傾きを調整する。具体的には、前輪側の脚の高さを「−x/4」して、後輪側の脚の高さを「+x/4」する。このことにより、フェーズ5の段階での車高は、すべての車輪20の位置で「L+x/4」となり、前後の車高も一致する。このように、フェーズ5の段階では、第三反転機構モータ120を作動させることで前後の傾きを無くすことが可能である。 Next, in Phase 5, that is, when the first reversing mechanism motor 140 and the second reversing mechanism motor 150 are operating, the front-rear inclination is adjusted by turning the gear 10s and the gear 10t in the same direction. Specifically, the height of the legs on the front wheel side is set to "-x / 4", and the height of the legs on the rear wheel side is set to "+ x / 4". As a result, the vehicle height at the stage of Phase 5 becomes "L + x / 4" at all the wheel 20 positions, and the front and rear vehicle heights also match. As described above, in the stage of the phase 5, it is possible to eliminate the front-rear inclination by operating the third reversing mechanism motor 120.

最後に、フェーズ6すなわち第一反転機構モータ140、第二反転機構モータ150、及び第三反転機構モータ120作動時には、ギア10sとギア10tとを相互に反対方向(図6の矢印の方向)に旋回させることで、車高を調整する。具体的には、各車輪20の脚の高さを「+H」する。このことにより、フェーズ6の段階での車高は、すべての車輪20の位置で「L+x/4+H」となる。このように、フェーズ6の段階では、第一反転機構モータ140及び第二反転機構モータ150を作動させることで車高を調整できる。 Finally, when Phase 6, that is, the first reversing mechanism motor 140, the second reversing mechanism motor 150, and the third reversing mechanism motor 120 are operating, the gears 10s and 10t are oriented in opposite directions (in the direction of the arrow in FIG. 6). Adjust the vehicle height by turning. Specifically, the height of the legs of each wheel 20 is "+ H". As a result, the vehicle height at the stage of Phase 6 becomes "L + x / 4 + H" at the positions of all the wheels 20. As described above, in the phase 6 stage, the vehicle height can be adjusted by operating the first reversing mechanism motor 140 and the second reversing mechanism motor 150.

(実施の形態4の効果)
このような本実施の形態4に係る制御機構4によれば、第一反転機構61、第二反転機構62、及び第三反転機構63を備えることにより、第一車輪21と第四車輪24のセット、及び第二車輪22と第三車輪23のセットを相互に上下反対方向に連動させて荷重配分できると共に、第一反転機構61、第二反転機構62、及び第三反転機構63を差動装置として構成し、第三反転機構モータ120によって、第一車輪21及び第二車輪22に対する車体70の位置と、第三車輪23及び第四車輪24に対する車体70の位置とが相互に上下反対方向に移動するように各旋回軸40を旋回させるので、第一車輪21及び第二車輪22側から第三車輪23及び第四車輪24側へと至るように車体70を傾けて姿勢制御することができ、また、第一反転機構モータ140及び第二反転機構モータ150によって、第一車輪21及び第三車輪23に対する車体70の位置と、第二車輪22及び第四車輪24に対する車体70の位置とが相互に上下反対方向に移動するように各旋回軸40を旋回させるので、第一車輪21及び第三車輪23側から第二車輪22及び第四車輪24側へと至るように車体70を傾けて姿勢制御することができ、さらに、第一車輪21、第二車輪22、第三車輪23、及び第四車輪24に対する車体70の位置が相互に上下同一方向に移動するように各旋回軸40を旋回させることで車体70の高さ調整ができるので、バネ、ワイヤ、又は流体式サスペンション等の複雑な機構を省略した極めて簡素な機構な機構により荷重配分、姿勢制御、及び高さ調整ができ、コストの削減や利用性の向上が可能となる。
(Effect of Embodiment 4)
According to the control mechanism 4 according to the fourth embodiment, the first wheel 21 and the fourth wheel 24 are provided with the first reversing mechanism 61, the second reversing mechanism 62, and the third reversing mechanism 63. The set and the set of the second wheel 22 and the third wheel 23 can be interlocked with each other in the opposite directions to distribute the load, and the first reversing mechanism 61, the second reversing mechanism 62, and the third reversing mechanism 63 are differentially arranged. It is configured as a device, and the position of the vehicle body 70 with respect to the first wheel 21 and the second wheel 22 and the position of the vehicle body 70 with respect to the third wheel 23 and the fourth wheel 24 are mutually upside down by the third reversing mechanism motor 120. Since each turning shaft 40 is swiveled so as to move to, the vehicle body 70 can be tilted to control the posture so as to reach from the first wheel 21 and the second wheel 22 side to the third wheel 23 and the fourth wheel 24 side. The position of the vehicle body 70 with respect to the first wheel 21 and the third wheel 23 and the position of the vehicle body 70 with respect to the second wheel 22 and the fourth wheel 24 by the first reversing mechanism motor 140 and the second reversing mechanism motor 150. Since each turning shaft 40 is swiveled so as to move in opposite directions to each other, the vehicle body 70 is tilted so as to reach the second wheel 22 and the fourth wheel 24 side from the first wheel 21 and the third wheel 23 side. The posture can be controlled, and the turning shafts 40 move in the same vertical direction with respect to the first wheel 21, the second wheel 22, the third wheel 23, and the fourth wheel 24. Since the height of the vehicle body 70 can be adjusted by turning the wheel, load distribution, attitude control, and height adjustment can be performed by an extremely simple mechanism that omits complicated mechanisms such as springs, wires, or fluid suspension. , Cost reduction and usability improvement are possible.

〔実施の形態に対する変形例〕
以上、本発明に係る実施の形態について説明したが、本発明の具体的な構成及び手段は、特許請求の範囲に記載した各発明の技術的思想の範囲内において、任意に改変及び改良することができる。以下、このような変形例について説明する。
[Modified example with respect to the embodiment]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention may be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can be done. Hereinafter, such a modification will be described.

(解決しようとする課題や発明の効果について)
まず、発明が解決しようとする課題や発明の効果は、上述の内容に限定されるものではなく、発明の実施環境や構成の細部に応じて異なる可能性があり、上述した課題の一部のみを解決する場合や、上述した効果の一部のみを奏することがある。
(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. In some cases, only a part of the above-mentioned effects may be produced.

(各実施の形態の相互関係)
各実施の形態に示した特徴は、相互に入れ替えたり、一方の特徴を他方に追加したりしてもよい。例えば、実施の形態2に係る第三連結軸53及び第一第二反転機構モータ130の代わりに、実施の形態4に係る第一反転機構モータ140及び第二反転機構モータ150を設けても良い。
(Interrelationship of each embodiment)
The features shown in each embodiment may be interchanged or one feature may be added to the other. For example, instead of the third connecting shaft 53 and the first second reversing mechanism motor 130 according to the second embodiment, the first reversing mechanism motor 140 and the second reversing mechanism motor 150 according to the fourth embodiment may be provided. ..

(寸法や材料について)
発明の詳細な説明や図面で説明した制御機構の各部の寸法、形状、材料、比率等は、あくまで例示であり、その他の任意の寸法、形状、材料、比率等とすることができる。また、各ギア、車輪20、旋回軸40、連結軸50、及びモータの組み合わせや配置箇所や向きについても例示に過ぎず、同様の作用を実現するために他の態様を適用して構わない。
(About dimensions and materials)
The dimensions, shapes, materials, ratios, etc. of each part of the control mechanism described in the detailed description of the invention and the drawings are merely examples, and other arbitrary dimensions, shapes, materials, ratios, etc. can be used. Further, the combination, arrangement location, and orientation of each gear, wheel 20, swivel shaft 40, connecting shaft 50, and motor are merely examples, and other aspects may be applied in order to realize the same operation.

(旋回機構及び接地部について)
各実施の形態においては、図1に示すように、前輪側の旋回軸40を左方(−X方向)から見て時計回りさせることで前輪を上昇させ、左方から見て反時計回りさせることで前輪を下降させており、一方、後輪側の旋回軸40を左方から見て時計回りさせることで後輪を下降させ、左方から見て反時計回りさせることで後輪を上昇させたが、車輪20を上昇又は下降させるための各旋回機構30の旋回方向を例示に過ぎず、これに限定されない。図8は、第一の変形例に係る制御機構5の共通部を模式的に示す平面図である。例えば、この図8に示すように旋回機構30や各ギアを構成することにより、後輪側の旋回軸40を左方から見て時計回りさせることで後輪を上昇させ、左方から見て反時計回りさせることで後輪を下降させても構わない。
(About swivel mechanism and grounding part)
In each embodiment, as shown in FIG. 1, the front wheel is raised by rotating the turning shaft 40 on the front wheel side clockwise when viewed from the left (-X direction), and counterclockwise when viewed from the left. By doing so, the front wheels are lowered, while the rear wheels are lowered by turning the turning shaft 40 on the rear wheel side clockwise when viewed from the left, and the rear wheels are raised by turning the turning shaft 40 counterclockwise when viewed from the left. However, the turning direction of each turning mechanism 30 for raising or lowering the wheel 20 is merely an example, and the present invention is not limited to this. FIG. 8 is a plan view schematically showing a common portion of the control mechanism 5 according to the first modification. For example, as shown in FIG. 8, by configuring the turning mechanism 30 and each gear, the turning shaft 40 on the rear wheel side is rotated clockwise when viewed from the left, thereby raising the rear wheel and viewed from the left. The rear wheel may be lowered by turning it counterclockwise.

各実施の形態においては、接地部は車輪20であるものとして説明したが、これに限らず、接地可能な様々な構成を採用できる。図9は、第二の変形例に係る制御機構6を模式的に示す左側面図である。この図9に示すように、例えば車輪20の代わりに揺動形クローラ160を用いて、不整地でも移動能力を向上させても構わない。 In each embodiment, the ground contact portion has been described as being the wheel 20, but the ground contact portion is not limited to this, and various configurations that can be grounded can be adopted. FIG. 9 is a left side view schematically showing the control mechanism 6 according to the second modification. As shown in FIG. 9, for example, a swinging crawler 160 may be used instead of the wheel 20 to improve the moving ability even on rough terrain.

また、階段や急斜面を安定姿勢で走行させるために、接地部のストロークを大きくするための機構を設けても構わない。図10は、第三の変形例に係る制御機構7を模式的に示す左側面図、図11は、前後の傾きを調整する制御機構7を模式的に示す左側面図、図12は、第四の変形例に係る制御機構8を模式的に示す左側面図である。これらの図10及び図11に示すように、平行リンク170を利用するか、あるいは、図12に示すように、ラックピニオン機構180を利用することにより、ストロークを大きくすることが可能となり、階段や急斜面における安定性を向上させることが可能となる。なお、図示は省略するが、歯車やチェーンを差動機構に組み込んでも構わない。また、図10から後述する図13では図示の便宜上、車高検出用センサ80、傾斜計90、及び制御部100を省略している。 Further, in order to run the stairs and steep slopes in a stable posture, a mechanism for increasing the stroke of the ground contact portion may be provided. 10 is a left side view schematically showing the control mechanism 7 according to the third modification, FIG. 11 is a left side view schematically showing the control mechanism 7 for adjusting the front-rear inclination, and FIG. 12 is a second side view. It is a left side view which shows typically the control mechanism 8 which concerns on 4th modification. By using the parallel link 170 as shown in FIGS. 10 and 11 or by using the rack and pinion mechanism 180 as shown in FIG. 12, the stroke can be increased, and the stairs and stairs can be used. It is possible to improve the stability on steep slopes. Although not shown, gears and chains may be incorporated into the differential mechanism. Further, in FIG. 13 described later from FIG. 10, for convenience of illustration, the vehicle height detection sensor 80, the inclinometer 90, and the control unit 100 are omitted.

まず、図13は、第五の変形例に係る制御機構9を模式的に示す左側面図である。この図13に示すように、車輪20の代わりに固定三角クローラ190を設けても構わない。すなわち、上記の車輪20では大きな段差や階段の走行が困難な可能性があり、また、上記の揺動形クローラ160では段差や階段の走破性は高いが前後方向に長くなるため狭小部の旋回が困難となり、また旋回時に床を傷つけてしまう可能性がある。しかし、このような固定三角クローラ190によれば、揺動形クローラ160と比較して短い全長で大きな段差や階段の昇降が可能となり、車輪20と同様のステアリングが可能であるため、床を傷つける可能性を低減できる。 First, FIG. 13 is a left side view schematically showing the control mechanism 9 according to the fifth modification. As shown in FIG. 13, a fixed triangular crawler 190 may be provided instead of the wheel 20. That is, it may be difficult for the wheel 20 to run on a large step or stairs, and the swinging crawler 160 has high running performance on the step or stairs but becomes longer in the front-rear direction, so that the narrow portion turns. It becomes difficult and there is a possibility of damaging the floor when turning. However, according to such a fixed triangular crawler 190, it is possible to go up and down a large step or stairs with a shorter overall length than the swing type crawler 160, and the same steering as the wheel 20 is possible, so that the floor is damaged. The possibility can be reduced.

(車高検出用センサについて)
各実施の形態において、車高検出用センサ80は車体70の下方に一つ取り付けられているものとして説明したが、段差の高さxを求めることが可能である限り、配置や個数はこれに限定されない。例えば、車両10の進行方向前方に向けて超音波を発して、車両10が段差に乗り上げる前段階で段差の高さxを検出するセンサとしても良い。
(About the vehicle height detection sensor)
In each embodiment, the vehicle height detection sensor 80 has been described as being attached to the lower part of the vehicle body 70, but as long as the height x of the step can be obtained, the arrangement and the number of the sensors 80 are limited to this. Not limited.
