本実施形態の非接触給電システムＡ１は、図１に示すように、蓄電池３２０（図９参照）の電力を用いて移動可能な電動移動体３に対して非接触で給電するために用いられる。 As shown in FIG. 1, the contactless power supply system A1 of the present embodiment is used to contactlessly supply power to the movable electric vehicle 3 using the power of the storage battery 320 (see FIG. 9).

非接触給電システムＡ１は、受電部２０と、非接触給電装置１と、を備える。受電部２０は、蓄電池３２０の電力を用いて移動可能な電動移動体３に設けられる。非接触給電装置１は、駐車中の電動移動体３の蓄電池３２０に、非接触給電トランスＴＲ１を用いて給電する。非接触給電装置１は、非接触給電トランスＴＲ１の送電部１０を有する。電動移動体３の駐車中に、送電部１０において受電部２０と対向する第１面１２と、受電部２０において送電部１０と対向する第２面２２とが互いに接触した状態で、送電部１０が受電部２０に非接触で給電する。非接触給電システムＡ１は、第１面１２及び第２面２２のうち少なくとも一方の面の向きを変更可能な支持部７０を、更に備えている。 A contactless power supply system A1 includes a power receiving unit 20 and a contactless power supply device 1 . The power receiving unit 20 is provided in the electric vehicle 3 that can move using the power of the storage battery 320 . The non-contact power supply device 1 supplies power to the storage battery 320 of the electric vehicle 3 that is parked using the non-contact power supply transformer TR1. The contactless power supply device 1 has a power transmission section 10 of a contactless power supply transformer TR1. While the motor-driven movable body 3 is parked, the first surface 12 of the power transmitting unit 10 facing the power receiving unit 20 and the second surface 22 of the power receiving unit 20 facing the power transmitting unit 10 are in contact with each other. supplies power to the power receiving unit 20 in a non-contact manner. The non-contact power feeding system A1 further includes a support portion 70 capable of changing the orientation of at least one of the first surface 12 and the second surface 22 .

本実施形態では、非接触給電システムＡ１が給電する対象の電動移動体３は、例えば電動自転車である。なお、電動移動体３は、電動自転車に限定されず、電動モータ付きのキックボード、電動モータ付きの三輪車、電動車椅子、３輪又は４輪の小型モビリティ、又は電動自動車等でもよい。以下の実施形態では電動移動体３が電動自転車である場合について説明する。 In this embodiment, the electric vehicle 3 to which power is supplied by the contactless power supply system A1 is, for example, an electric bicycle. The electric vehicle 3 is not limited to an electric bicycle, and may be a kickboard with an electric motor, a tricycle with an electric motor, an electric wheelchair, a three- or four-wheeled small mobility vehicle, an electric automobile, or the like. In the following embodiment, the case where the electric vehicle 3 is an electric bicycle will be described.

ここにおいて、「非接触で給電」するとは、送電部１０と受電部２０との間が電線等を介して物理的に接続されていない状態で給電することをいう。したがって、非接触で給電するとは、送電部１０の第１面１２と受電部２０の第２面２２とが互いに接触しているが、送電部１０と受電部２０とが互いに連結されていない状態で給電することを含み得る。 Here, "contactless power feeding" means power feeding in a state in which the power transmitting unit 10 and the power receiving unit 20 are not physically connected via an electric wire or the like. Therefore, power is supplied in a non-contact state in which the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception unit 20 are in contact with each other, but the power transmission unit 10 and the power reception unit 20 are not connected to each other. can include feeding with a

本実施形態の非接触給電システムＡ１では、支持部７０が、第１面１２及び第２面２２のうち少なくとも一方の面の向きを変更可能であるので、第１面１２と第２面２２とが接触する際に第１面１２と第２面２２との間にできる隙間を小さくできる。したがって、送電部１０と受電部２０との間での電力の伝達効率が低下する可能性を低減でき、電力の伝達効率の低下を抑制可能な非接触給電システムＡ１を提供することができる。 In the contactless power supply system A1 of the present embodiment, since the support part 70 can change the orientation of at least one of the first surface 12 and the second surface 22, the first surface 12 and the second surface 22 The gap formed between the first surface 12 and the second surface 22 can be made smaller when the two come into contact with each other. Therefore, it is possible to reduce the possibility that the power transmission efficiency between the power transmission unit 10 and the power reception unit 20 will decrease, and to provide the contactless power supply system A1 that can suppress the decrease in the power transmission efficiency.

本実施形態の非接触給電システムＡ１は電動移動体３を更に備える。非接触給電システムＡ１は上述の保持部（コイルばね９０）を備えているので、電力の伝達効率の低下を抑制可能な非接触給電システムＡ１を提供することができる。 The contactless power supply system A1 of this embodiment further includes an electric vehicle 3 . Since the contactless power supply system A1 includes the above-described holding portion (coil spring 90), it is possible to provide the contactless power supply system A1 capable of suppressing a decrease in power transmission efficiency.

（２）詳細

FIG. In the following description, the X-axis direction in FIGS. 1 and 3 to 5 is defined as the horizontal direction, the Y-axis direction as the front-rear direction (depth direction), and the Z-axis direction as the vertical direction. Further, the positive direction of the X-axis direction is defined as the right side, the positive direction of the Y-axis direction is defined as the front side, and the positive direction of the Z-axis direction is defined as the upper side. However, these directions are examples, and are not meant to limit the directions during use of the contactless power supply system A1. In addition, the arrows indicating each direction in the drawings are only shown for explanation and are not substantial.

非接触給電システムＡ１は、送電部１０を有する非接触給電装置１と、受電部２０を有する非接触受電装置２とを備える。本実施形態では、非接触受電装置２は取付部材４を用いて電動移動体３に取り付けられている。非接触給電装置１は、電動移動体３の駐車時に、非接触受電装置２に対して電力を供給し、非接触受電装置２を介して電動移動体３の蓄電池３２０を充電するために使用される。以下、電動移動体３、非接触受電装置２、取付部材４及び非接触給電装置１についてそれぞれ説明する。 A contactless power feeding system A1 includes a contactless power feeding device 1 having a power transmitting section 10 and a contactless power receiving device 2 having a power receiving section 20 . In this embodiment, the contactless power receiving device 2 is attached to the electric vehicle 3 using the attachment member 4 . The non-contact power supply device 1 is used to supply electric power to the non-contact power receiving device 2 and charge the storage battery 320 of the electric vehicle 3 via the non-contact power receiving device 2 when the electric vehicle 3 is parked. be. The electric vehicle 3, the non-contact power receiving device 2, the mounting member 4, and the non-contact power feeding device 1 will be described below.

（２．１）電動移動体
電動移動体３は、例えば、電動機で人力を補助する電動アシスト自転車である。なお、電動移動体３は、電動機のみで走行可能な電動自転車でもよい。 (2.1) Electric Vehicle The electric vehicle 3 is, for example, an electrically assisted bicycle that uses an electric motor to assist human power. Note that the electric vehicle 3 may be an electric bicycle that can run only with an electric motor.

電動移動体３は、図９に示すように、蓄電池３２０と、蓄電池３２０を充電する充電回路３２１とを有する。また、電動移動体３は、車輪（例えば後輪）に回転力を加える電動機と、蓄電池３２０に蓄えられた電力で電動機を回転させる制御回路とを備える。この制御回路は、例えば人がペダルを踏む力をセンサ等で検出し、センサの検出結果に基づいて電動機の回転力を制御する。 The electric vehicle 3 has a storage battery 320 and a charging circuit 321 for charging the storage battery 320, as shown in FIG. The electric vehicle 3 also includes an electric motor that applies rotational force to wheels (for example, rear wheels) and a control circuit that rotates the electric motor with electric power stored in the storage battery 320 . This control circuit detects, for example, the force of a person stepping on a pedal with a sensor or the like, and controls the torque of the electric motor based on the detection result of the sensor.

電動移動体３の車体３０１は、図９及び図１０に示すように、車輪（例えば前輪３１０）の車軸３１１を保持する二股のフォーク部（フロントフォーク）３０２を備えている。ここで、フォーク部３０２を含む車体３０１の一部に受電部２０を取り付けるための取付部材４と、車軸３１１とがフォーク部３０２に共締めされている。これにより、電動移動体３において前輪３１０の車軸３１１をフォーク部３０２に固定するための構成を利用して受電部２０を車体３０１に取り付けることができるので、簡易な構成で受電部２０を電動移動体３に取り付けることができる。なお、取付部材４については、「（２．３）取付部材」の欄で詳しく説明する。 As shown in FIGS. 9 and 10, the vehicle body 301 of the electric vehicle 3 includes a bifurcated fork portion (front fork) 302 that holds an axle 311 of a wheel (for example, a front wheel 310). Here, a mounting member 4 for mounting power reception unit 20 to a portion of vehicle body 301 including fork portion 302 and axle 311 are fastened together to fork portion 302 . As a result, the power receiving unit 20 can be attached to the vehicle body 301 using the configuration for fixing the axle 311 of the front wheel 310 to the fork portion 302 in the electric vehicle 3, so that the power receiving unit 20 can be electrically moved with a simple configuration. It can be attached to the body 3. The mounting member 4 will be described in detail in the section "(2.3) Mounting member".

（２．２）非接触受電装置
非接触受電装置２は、図１、図９及び図１０に示すように、受電部２０と、受電部２０を保持するベース部材２７と、を備えている。非接触受電装置２の受電部２０は、電動移動体３が備える車輪に対して固定された位置に配置されており、本実施形態では受電部２０は前輪３１０に対して固定された位置に配置されている。さらに言えば、受電部２０は、電動移動体３が備える車輪（例えば前輪３１０）の車軸３１１の延長線Ｌ１上に配置されるように、電動移動体３の車体３０１（例えばフォーク部３０２）に取り付けられている。したがって、送電部１０及び受電部２０は、車輪（前輪３１０）の車軸３１１の延長線Ｌ１上で対向している。電動移動体３の車輪（前輪３１０）の寸法及び形状は走行性能に大きく影響するため、一般的に高い寸法精度が要求されている。本実施形態では、受電部２０が車輪（前輪３１０）に対して固定された位置であって、例えば車軸３１１の延長線Ｌ１上に配置されているので、車体３０１において受電部２０の位置のずれが抑制される。したがって、送電部１０と受電部２０との相対的な位置ずれを低減でき、送電部１０と受電部２０との間での電力の伝達効率の低下を抑制できる。また、電動移動体３では、保持部（コイルばね９０）による押し付け力を車軸３１１及びその周辺で受けることができるので、電動移動体３において保持部（コイルばね９０）による押し付け力を受ける部位の強度を高めやすいという利点がある。 (2.2) Non-Contact Power Receiving Device As shown in FIGS. 1, 9 and 10, the non-contact power receiving device 2 includes a power receiving section 20 and a base member 27 that holds the power receiving section 20 . The power receiving unit 20 of the non-contact power receiving device 2 is arranged at a position fixed with respect to the wheels of the electric vehicle 3. In this embodiment, the power receiving unit 20 is arranged at a position fixed with respect to the front wheels 310. It is Furthermore, the power receiving unit 20 is attached to the vehicle body 301 (for example, the fork portion 302) of the electric vehicle 3 so as to be arranged on the extension line L1 of the axle 311 of the wheel (for example, the front wheel 310) of the electric vehicle 3. installed. Therefore, power transmission unit 10 and power reception unit 20 face each other on extension line L1 of axle 311 of the wheel (front wheel 310). Since the size and shape of the wheels (front wheels 310) of the electric vehicle 3 greatly affect the running performance, generally high dimensional accuracy is required. In the present embodiment, the power receiving unit 20 is fixed to the wheel (front wheel 310), for example, on the extension line L1 of the axle 311. Therefore, the positional deviation of the power receiving unit 20 in the vehicle body 301 does not occur. is suppressed. Therefore, relative positional deviation between power transmission unit 10 and power reception unit 20 can be reduced, and a decrease in power transmission efficiency between power transmission unit 10 and power reception unit 20 can be suppressed. In addition, in the electric vehicle 3, the pressing force of the holding portion (coil spring 90) can be received by the axle 311 and its periphery. There is an advantage that it is easy to increase the strength.

受電部２０は、受電コイルを有する受電モジュール２１と、受電モジュール２１の側面を少なくとも覆う受電側カバー２３とを備える。 The power receiving unit 20 includes a power receiving module 21 having a power receiving coil, and a power receiving side cover 23 that covers at least side surfaces of the power receiving module 21 .

受電モジュール２１は、例えばスパイラルコイルのような受電コイルと、受電用電源回路とを合成樹脂製のケース内に収容して構成される。受電モジュール２１は、送電部１０と対向する第２面２２を有している。第２面２２の平面視の形状は略円形である。送電部１０と受電部２０との間では例えば電磁誘導方式で非接触給電が行われる。送電部１０の第１面１２と受電モジュール２１の第２面２２とが対向した状態で、送電部１０の送電コイルに高周波の電流が流れると、送電コイルと受電コイルとの間に誘導磁束が発生し、受電コイルに所定周波数の高周波電流が流れる。受電モジュール２１の受電用電源回路は、受電コイルに流れる電流を整流、平滑することで、所定の電圧値（例えばＤＣ２４Ｖ）の直流電圧を発生する。受電モジュール２１は電線２９を介して充電回路３２１に接続されており、充電回路３２１は受電モジュール２１から直流電力の供給を受けて蓄電池３２０を充電する。なお、非接触給電システムＡ１が採用する非接触給電方式は、電磁誘導方式に限定されず、磁気共鳴方式、電界結合方式、又は直流共鳴方式等の非接触給電方式でもよい。 The power receiving module 21 is configured by housing a power receiving coil such as a spiral coil and a power receiving power supply circuit in a synthetic resin case. The power receiving module 21 has a second surface 22 facing the power transmitting section 10 . The shape of the second surface 22 in plan view is substantially circular. Contactless power supply is performed between the power transmission unit 10 and the power reception unit 20 by, for example, an electromagnetic induction method. When the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception module 21 face each other, when a high-frequency current flows through the power transmission coil of the power transmission unit 10, magnetic flux is induced between the power transmission coil and the power reception coil. A high-frequency current of a predetermined frequency flows through the receiving coil. The power receiving power supply circuit of the power receiving module 21 rectifies and smoothes the current flowing through the power receiving coil to generate a DC voltage of a predetermined voltage value (for example, 24 V DC). The power receiving module 21 is connected to a charging circuit 321 via an electric wire 29 , and the charging circuit 321 receives DC power from the power receiving module 21 to charge the storage battery 320 . The non-contact power supply system adopted by the non-contact power supply system A1 is not limited to the electromagnetic induction system, and may be a non-contact power supply system such as a magnetic resonance system, an electric field coupling system, or a direct current resonance system.

ベース部材２７は円板状の金属板を有している。ベース部材２７の一面には、受電モジュール２１が例えばねじ又はスナップフィット等の適宜の方法で取り付けられている。また、ベース部材２７の一面には、受電モジュール２１を覆うようにして、受電側カバー２３がねじ又はスナップフィット等の適宜の方法で取り付けられている。 The base member 27 has a disk-shaped metal plate. The power receiving module 21 is attached to one surface of the base member 27 by an appropriate method such as screws or snap fitting. A power receiving side cover 23 is attached to one surface of the base member 27 by an appropriate method such as screws or snap fitting so as to cover the power receiving module 21 .

受電側カバー２３は、円環状の前壁２４と、前壁２４の外周縁から送電部１０と反対側に突出する周壁２６とを備えている。前壁２４の中央には、受電モジュール２１の第２面２２を露出させる円形の窓孔２５が設けられている。前壁２４の表面は、外側に行くほど送電部１０から離れる向きに傾斜する傾斜面２４Ａとなっている。 The power receiving side cover 23 includes an annular front wall 24 and a peripheral wall 26 protruding from the outer peripheral edge of the front wall 24 to the side opposite to the power transmission section 10 . A circular window hole 25 that exposes the second surface 22 of the power receiving module 21 is provided in the center of the front wall 24 . The surface of the front wall 24 is an inclined surface 24A inclined in a direction away from the power transmission section 10 toward the outside.

ここにおいて、窓孔２５から露出する第２面２２と、受電側カバー２３とで、受電コイルを覆う第２カバー部２８（図９及び図１０参照）が構成される。つまり、受電部２０は、受電コイルと、第２面２２を含んで受電コイルを覆う第２カバー部２８とを有している。なお、本実施形態では第２面２２と、受電側カバー２３とが別体であるが、第２面２２を有する受電モジュール２１と受電側カバー２３とが一体の部品（第２カバー部２８）として形成されてもよい。また、受電側カバー２３が、受電モジュール２１におけるベース部材２７と反対側の面を覆ってもよく、この場合は受電側カバー２３の表面が第２面２２となる。 Here, the second surface 22 exposed from the window hole 25 and the power receiving side cover 23 constitute a second cover portion 28 (see FIGS. 9 and 10) that covers the power receiving coil. That is, the power receiving unit 20 has a power receiving coil and a second cover part 28 that includes the second surface 22 and covers the power receiving coil. In this embodiment, the second surface 22 and the power receiving side cover 23 are separate members, but the power receiving module 21 having the second surface 22 and the power receiving side cover 23 are integral parts (second cover portion 28). may be formed as Alternatively, the power receiving side cover 23 may cover the surface of the power receiving module 21 opposite to the base member 27 , in which case the surface of the power receiving side cover 23 serves as the second surface 22 .

（２．３）取付部材
取付部材４は、電動移動体３の前輪３１０を保持するフォーク部３０２に非接触受電装置２を取り付けるために用いられる。 (2.3) Attachment Member The attachment member 4 is used to attach the non-contact power receiving device 2 to the fork portion 302 that holds the front wheel 310 of the electric vehicle 3 .

取付部材４は、図１０に示すように、前輪３１０の車軸３１１を挿入するための貫通孔４２が設けられた矩形板状のベース部４１を有している。ベース部４１の３辺には受電部２０が取り付けられる受電部取付部４３がそれぞれ設けられ、ベース部４１の残りの１辺からは延伸部４４が延びている。つまり、取付部材４は、車輪（例えば前輪３１０）の車軸３１１を挿入するための貫通孔４２を有するベース部４１と、ベース部４１の周縁部に設けられて受電部２０が取り付けられる受電部取付部４３と、を有している。受電部２０は取付部材４を用いて電動移動体３の車体３０１に取り付けられるので、車軸３１１をフォーク部３０２に固定するための構成を利用して受電部２０を車体３０１に取り付けることができる。 As shown in FIG. 10 , the mounting member 4 has a rectangular plate-shaped base portion 41 provided with a through hole 42 for inserting an axle 311 of a front wheel 310 . Three sides of the base portion 41 are provided with power receiving portion attachment portions 43 to which the power receiving portion 20 is attached, and an extension portion 44 extends from the remaining one side of the base portion 41 . That is, the mounting member 4 includes a base portion 41 having a through hole 42 for inserting an axle 311 of a wheel (for example, a front wheel 310), and a power receiving portion mounting portion provided on the periphery of the base portion 41 to which the power receiving portion 20 is attached. a portion 43; Since power receiving unit 20 is attached to vehicle body 301 of electric vehicle 3 using attachment member 4 , power receiving unit 20 can be attached to vehicle body 301 using a configuration for fixing axle 311 to fork portion 302 .

受電部取付部４３は側面視の形状がＬ形に形成されており、受電部取付部４３において受電部２０が固定される部位は、ベース部４１に対して、車輪（前輪３１０）と反対側に位置をずらして配置されている。つまり、受電部取付部４３は、ベース部４１に対して車輪（前輪３１０）と反対側に配置されており、受電部２０は、ベース部４１に対して車輪（前輪３１０）と反対側で、受電部取付部４３に取り付けられている。すなわち、受電部取付部４３において受電部２０が固定される部位と、ベース部４１との間には、車軸３１１の軸方向において間隔が開けられており、受電部取付部４３に固定される受電部２０は、ベース部４１に対して車輪（前輪３１０）と反対側に配置されている。これにより、受電部取付部４３に取り付けられる受電部２０とベース部４１との間に間隔を開けた状態で受電部２０を配置することができる。したがって、受電部取付部４３に取り付けられる受電部２０とベース部４１との間に、取付部材４と車軸３１１とをフォーク部３０２に共締めするための部材（例えばナット４６）を配置することができる。 The power receiving unit mounting portion 43 is L-shaped when viewed from the side, and the portion of the power receiving unit mounting portion 43 to which the power receiving unit 20 is fixed is on the opposite side of the base portion 41 from the wheels (front wheels 310). are staggered to each other. That is, the power receiving unit mounting portion 43 is arranged on the side opposite to the wheels (front wheels 310) with respect to the base portion 41, and the power receiving portion 20 is arranged on the side opposite to the wheels (front wheels 310) with respect to the base portion 41. It is attached to the power receiving unit attachment portion 43 . That is, there is a space in the axial direction of the axle 311 between the portion of the power receiving unit mounting portion 43 to which the power receiving unit 20 is fixed and the base portion 41 , and the power receiving portion fixed to the power receiving unit mounting portion 43 The portion 20 is arranged on the side opposite to the wheel (front wheel 310) with respect to the base portion 41. As shown in FIG. Accordingly, the power receiving unit 20 can be arranged with a gap between the power receiving unit 20 attached to the power receiving unit attachment portion 43 and the base portion 41 . Therefore, a member (for example, nut 46) for fastening together mounting member 4 and axle 311 to fork portion 302 can be arranged between power receiving portion 20 and base portion 41 attached to power receiving portion mounting portion 43. can.

ここで、延伸部４４は、車軸３１１の軸方向（図９及び図１０の線Ｌ１と平行な方向）と交差する方向に延びており、この延伸部４４がフォーク部３０２に固定される。本実施形態では延伸部４４はフォーク部３０２に沿って延びている。延伸部４４には固定用のねじ４８を挿入するための貫通孔４５が延出方向に沿って複数設けられている。なお、延伸部４４に複数の貫通孔４５が設けられることは必須ではなく、少なくとも１つの貫通孔４５が設けられていればよい。 Here, the extending portion 44 extends in a direction crossing the axial direction of the axle 311 (the direction parallel to the line L1 in FIGS. 9 and 10), and is fixed to the fork portion 302 . In this embodiment, extension 44 extends along fork 302 . A plurality of through holes 45 for inserting fixing screws 48 are provided in the extending portion 44 along the extending direction. It should be noted that it is not essential to provide a plurality of through-holes 45 in the extending portion 44, and at least one through-hole 45 may be provided.

この取付部材４と前輪３１０の車軸３１１とはフォーク部３０２の先端部分に共締めされる。取付部材４をフォーク部３０２に取り付ける際には、まずフォーク部３０２の先端部分の溝に車軸３１１を通し、この車軸３１１にベース部４１の貫通孔４２とワッシャ４７とを通す。そして、車軸３１１の先端部分のねじ部にナット４６をねじ込むことによって、車軸３１１と取付部材４とをフォーク部３０２の先端部分である第１部位３０４（図１０参照）に共締めする。 The mounting member 4 and the axle 311 of the front wheel 310 are fastened together to the tip portion of the fork portion 302 . When attaching the mounting member 4 to the fork portion 302 , first, the axle 311 is passed through the groove in the tip portion of the fork portion 302 , and the through hole 42 of the base portion 41 and the washer 47 are passed through the axle 311 . Then, by screwing the nut 46 onto the threaded portion of the tip portion of the axle 311, the axle 311 and the mounting member 4 are fastened together to the first portion 304 (see FIG. 10) which is the tip portion of the fork portion 302. As shown in FIG.

そして、フォーク部３０２に設けられた固定片３０３のねじ孔と、延伸部４４の貫通孔４５とを位置合わせした後、ねじ４８のねじ部をワッシャ４９と貫通孔４５とに通して固定片３０３のねじ孔にねじ込むことで、延伸部４４をフォーク部３０２に固定する。つまり、フォーク部３０２の先端側の第１部位３０４で車軸３１１と取付部材４とが共締めされるとともに、取付部材４は、フォーク部３０２において第１部位３０４以外の第２部位３０５で更に固定されている。取付部材４は、フォーク部３０２において第１部位３０４以外の第２部位３０５でも固定されているので、取付部材４のベース部４１が車軸３１１の周りに回転しにくくなる。ベース部４１が車軸３１１の周りに回転すると、ナット４６が緩みやすくなるが、本実施形態では取付部材４を第２部位３０５でも固定することで、取付部材４が回転しにくくなる。したがって、車軸３１１を固定するナット４６が緩みにくくなり、車軸３１１の固定状態が緩む可能性を低減できる。 Then, after aligning the screw hole of the fixed piece 303 provided in the fork portion 302 with the through hole 45 of the extension portion 44 , the threaded portion of the screw 48 is passed through the washer 49 and the through hole 45 to secure the fixed piece 303 . The extension portion 44 is fixed to the fork portion 302 by screwing it into the threaded hole of . That is, the axle 311 and the mounting member 4 are fastened together at the first portion 304 on the tip side of the fork portion 302, and the mounting member 4 is further fixed at the second portion 305 other than the first portion 304 in the fork portion 302. It is Since the attachment member 4 is also fixed at the second portion 305 other than the first portion 304 at the fork portion 302 , the base portion 41 of the attachment member 4 is less likely to rotate around the axle 311 . When the base portion 41 rotates around the axle 311, the nut 46 is likely to be loosened. However, in this embodiment, by fixing the mounting member 4 at the second portion 305 as well, the mounting member 4 is less likely to rotate. Therefore, the nut 46 that fixes the axle 311 is less likely to loosen, and the possibility that the fixed state of the axle 311 will loosen can be reduced.

次に、取付部材４がフォーク部３０２に固定された状態で、各受電部取付部４３の貫通孔に通した固定ねじ４３１（図１参照）を、受電部２０のベース部材２７のねじ孔にねじ込むことによって、受電部２０が取付部材４に固定される。これにより、受電部２０が取付部材４を介して電動移動体３のフォーク部３０２に取り付けられており、受電部２０は、電動移動体３が備える車輪（前輪３１０）の車軸３１１の延長線上に配置されている。 Next, with the mounting member 4 fixed to the fork portion 302 , the fixing screws 431 (see FIG. 1) passed through the through holes of the power receiving portion mounting portions 43 are inserted into the screw holes of the base member 27 of the power receiving portion 20 . The power receiving unit 20 is fixed to the mounting member 4 by screwing. As a result, the power receiving unit 20 is attached to the fork portion 302 of the electric vehicle 3 via the mounting member 4, and the power receiving unit 20 is arranged on the extension line of the axle 311 of the wheel (front wheel 310) of the electric vehicle 3. are placed.

上述のように、車輪（前輪３１０）には高い寸法精度が要求されるので、車軸３１１の延長線上に受電部２０が配置されることで、受電部２０の取付位置が精度よく定まる。よって、送電部１０と受電部２０との相対的な位置ずれを低減できるので、送電部１０と受電部２０との間の電力の伝達効率の低下を抑制できる。また、受電部２０は、ベース部４１に対して前輪（車輪）３１０と反対側で、受電部取付部４３に取り付けられており、ベース部４１に比べて車輪（前輪３１０）から離れた位置に配置できるので、受電部２０が車輪（前輪３１０）に接触する可能性を低減できる。また、受電部２０は、取付部材４を介して、車輪（前輪３１０）に対して固定された位置に配置されるので、電動移動体３が移動する場合でも受電部２０の位置がぐらつくのを抑制できる。 As described above, the wheels (front wheels 310) are required to have high dimensional accuracy. Therefore, by arranging power receiving unit 20 on the extension line of axle 311, the mounting position of power receiving unit 20 is determined with high accuracy. Therefore, since the relative positional deviation between power transmission unit 10 and power reception unit 20 can be reduced, a decrease in power transmission efficiency between power transmission unit 10 and power reception unit 20 can be suppressed. The power receiving unit 20 is attached to the power receiving unit mounting portion 43 on the side opposite to the front wheels (wheels) 310 with respect to the base portion 41 , and is located farther from the wheels (front wheels 310 ) than the base portion 41 . Since it can be arranged, the possibility that power receiving unit 20 contacts the wheel (front wheel 310) can be reduced. In addition, since the power receiving unit 20 is arranged at a fixed position with respect to the wheels (front wheels 310) via the mounting member 4, the position of the power receiving unit 20 does not wobble even when the electric vehicle 3 moves. can be suppressed.

本実施形態では、フォーク部３０２に沿って延びている延伸部４４が、フォーク部３０２に固定されるので、延伸部４４をフォーク部３０２に固定する作業がやりやすいという利点がある。 In this embodiment, since the extending portion 44 extending along the fork portion 302 is fixed to the fork portion 302, there is an advantage that the operation of fixing the extending portion 44 to the fork portion 302 is easy.

なお、本実施形態では、取付部材４の延伸部４４が、フォーク部３０２の固定片３０３に固定されているが、延伸部４４はフォーク部３０２に適宜の方法で固定されていればよい。例えば、合成樹脂製の結束バンドを用いて延伸部４４とフォーク部３０２とを一括りにしてもよいし、フォーク部３０２とは別体の金具を用いて延伸部４４をフォーク部３０２に固定してもよい。 In this embodiment, the extending portion 44 of the mounting member 4 is fixed to the fixing piece 303 of the fork portion 302, but the extending portion 44 may be fixed to the fork portion 302 by an appropriate method. For example, the extending portion 44 and the fork portion 302 may be bundled together using a binding band made of synthetic resin, or the extending portion 44 may be fixed to the fork portion 302 using a metal fitting separate from the fork portion 302. may

また、取付部材４が第１部位３０４以外で車体３０１に固定される部位は、フォーク部３０２に限定されず、車体３０１におけるフォーク部３０２以外の部位（例えばフレーム等）に取り付けられてもよい。また、取付部材４は、電動移動体３の後輪を保持するフォーク部に取り付けられてもよい。 Moreover, the part where the mounting member 4 is fixed to the vehicle body 301 other than the first part 304 is not limited to the fork part 302, and may be attached to a part of the vehicle body 301 other than the fork part 302 (for example, a frame or the like). Moreover, the mounting member 4 may be mounted on a fork portion that holds the rear wheel of the electric vehicle 3 .

The guide part 57 is configured to provide contactless power supply to guide the electric vehicle 3 (specifically, the front wheels 310, which are wheels of the electric vehicle 3) to a position where the first surface 12 and the second surface 22 face each other. provided in the device 1; The guide portion 57 is provided from near the front end to near the rear end of the wheel mounting portion 52 . A holding groove 58 recessed in an arc shape is provided in an intermediate portion of the guide portion 57 in the front-rear direction so that the front wheel 310 is fitted therein. The surface of the holding groove 58 is curved to match the inch diameter of the front wheel 310 of the electric vehicle 3 . At a portion of the guide portion 57 on the front side of the holding groove 58, an inclined portion 59 that is inclined with respect to the installation surface G1 is provided so that the height from the installation surface G1 decreases toward the front side. . Therefore, when guiding the wheel (front wheel 310) to the position where the first surface 12 and the second surface 22 face each other, the guide portion 57 guides the wheel to move upward.

支柱部５３は、上下方向に長い直方体状であって、上端部が曲面状に形成されている。支柱部５３は、台座部５１の上面において左端に寄せて設けられている。支柱部５３における車輪載置部５２側の側面６０には、車輪載置部５２の保持溝５８に前輪３１０が嵌った状態で、電動移動体３に設けられた受電部２０と対向する部位に、円形の窓孔６１が設けられている。また、支柱部５３の上部には、動作表示用の発光ダイオードＬＤ１の発光部分を露出するための貫通孔５６（図４参照）が設けられている。例えば、送電部１０が受電部２０に電力供給する場合に、発光ダイオードＬＤ１が点灯しており、ユーザは、発光ダイオードＬＤ１の発光状態に基づいて非接触給電装置１による給電状態を確認することができる。 The column portion 53 has a rectangular parallelepiped shape that is elongated in the vertical direction, and has a curved upper end portion.

A DC voltage of a predetermined voltage value (for example, 24 V DC) is supplied. The power supply circuit for power transmission converts the DC voltage supplied from the power supply unit 62 into a high-frequency current of a predetermined frequency, and supplies the high-frequency current to the power transmission coil.

ここで、車輪載置部５２に電動移動体３の前輪３１０が載せられていない待機状態では、送電用電源回路は、蓄電池３２０の充電時に比べて小さい待機電流を送電コイルに流している。車輪載置部５２に電動移動体３の前輪３１０が載せられ、送電部１０の第１面１２と受電部２０の第２面２２とが対向すると、送電コイルと受電コイルとの間に誘導磁束が発生し、受電コイルに高周波の電流が流れる。受電コイルに高周波の電流が流れることによって受電側電源回路に電力が供給されると、受電側電源回路が起動し、受電側電源回路と送電側電源回路との間で通信が行われる。送電側電源回路は、受電側電源回路との通信によって車輪載置部５２に電動移動体３の前輪３１０が載せられたことを検知すると、待機電流に比べて大きな電流を送電コイルに流し、蓄電池３２０を充電するのに必要な電力を受電部２０に供給する。 Here, in a standby state in which the front wheels 310 of the electric vehicle 3 are not placed on the wheel rests 52 , the power supply circuit for power transmission supplies a smaller standby current to the power transmission coil than when the storage battery 320 is charged. When the front wheel 310 of the electric vehicle 3 is placed on the wheel mounting portion 52 and the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception unit 20 face each other, magnetic flux is induced between the power transmission coil and the power reception coil. is generated, and a high-frequency current flows through the receiving coil. When power is supplied to the power supply circuit on the power receiving side by a high-frequency current flowing through the power receiving coil, the power supply circuit on the power receiving side is activated, and communication is performed between the power supply circuit on the power receiving side and the power supply circuit on the power transmission side. When the power transmission side power circuit detects that the front wheels 310 of the electric vehicle 3 are placed on the wheel mounting portions 52 through communication with the power reception side power circuit, a current larger than the standby current flows through the power transmission coil, and the storage battery 320 is supplied to the power receiving unit 20 .

ベース部材１７は円板状の金属板からなり、ベース部材１７の一面に送電モジュール１１がねじ又はスナップフィット等の適宜の方法で取り付けられている。また、ベース部材１７の一面には、送電モジュール１１を覆うようにして、送電側カバー１３がねじ又はスナップフィット等の適宜の方法で取り付けられている。 The base member 17 is made of a disk-shaped metal plate, and the power transmission module 11 is attached to one surface of the base member 17 by an appropriate method such as screws or snap fitting. A power transmission side cover 13 is attached to one surface of the base member 17 by an appropriate method such as screws or snap fitting so as to cover the power transmission module 11 .

送電側カバー１３は、図４及び図５に示すように円環状の前壁１４と、前壁１４の外周縁から受電部２０と反対側に突出する周壁１６とを備えている。前壁１４の中央には、送電モジュール１１の第１面１２を露出させる円形の窓孔１５が設けられている。前壁１４の表面は、外側に行くほど受電部２０から離れる向きに傾斜する傾斜面１４Ａとなっている。 The power transmission side cover 13 includes an annular front wall 14 and a peripheral wall 16 protruding from the outer peripheral edge of the front wall 14 to the side opposite to the power reception unit 20 as shown in FIGS. 4 and 5 . A circular window hole 15 that exposes the first surface 12 of the power transmission module 11 is provided in the center of the front wall 14 . The surface of the front wall 14 is an inclined surface 14A that is inclined away from the power receiving unit 20 toward the outside.

ここにおいて、窓孔１５から露出する第１面１２と、送電側カバー１３とで、送電コイルを覆う第１カバー部１８（図２及び図４参照）が構成される。つまり、送電部１０は、送電コイルと、第１面１２を含んで送電コイルを覆う第１カバー部１８とを有している。なお、本実施形態では第１面１２と、送電側カバー１３とが別体であるが、第１面１２を有する送電モジュール１１と送電側カバー１３とが一体の部品（第１カバー部１８）として形成されてもよい。また、送電側カバー１３が、送電モジュール１１におけるベース部材１７と反対側の面を覆ってもよく、この場合は送電側カバー１３の表面が第１面１２となる。 Here, the first surface 12 exposed from the window hole 15 and the power transmission side cover 13 constitute a first cover portion 18 (see FIGS. 2 and 4) that covers the power transmission coil. That is, the power transmission section 10 has a power transmission coil and a first cover portion 18 that includes the first surface 12 and covers the power transmission coil. In this embodiment, the first surface 12 and the power transmission side cover 13 are separate members, but the power transmission module 11 having the first surface 12 and the power transmission side cover 13 are integral parts (first cover portion 18). may be formed as Alternatively, the power transmission side cover 13 may cover the surface of the power transmission module 11 opposite to the base member 17 , in which case the surface of the power transmission side cover 13 is the first surface 12 .

送電部１０は、支持部７０を介して、支柱部５３内に配置されたフレーム５５に取り付けられている。支持部７０は、支持点ＳＰ１（図２参照）を中心として任意の方向に回転可能な状態で送電部１０を支持している。また、支持部７０は、送電部１０と受電部２０とが対向する対向方向（矢印ＤＲ１又はＤＲ２の方向）において変位可能な状態でフレーム５５に対して取り付けられており、コイルばね９０（保持部）によって受電部２０側に押し付けられている。つまり、保持部（コイルばね９０）は、第１面１２と第２面２２とを弾性力で押し付けている。 The power transmission section 10 is attached to the frame 55 arranged inside the support section 53 via the support section 70 . The support portion 70 supports the power transmission portion 10 in a rotatable state in any direction about the support point SP1 (see FIG. 2). Further, the support portion 70 is attached to the frame 55 so as to be displaceable in the opposing direction (the direction of the arrow DR1 or DR2) in which the power transmission portion 10 and the power reception portion 20 face each other. ) is pressed against the power receiving unit 20 side. That is, the holding portion (coil spring 90) presses the first surface 12 and the second surface 22 with an elastic force.

支持部７０は、取付板７１と、ジョイント部材７３と、スライド部材７７とを備えている。 The support portion 70 includes a mounting plate 71 , a joint member 73 and a slide member 77 .

取付板７１は金属製の板金に曲げ加工を施して形成されている。取付板７１における送電部１０側の面には、送電部１０側に突出するＬ形の脚部７２が複数（例えば４つ）設けられており、各脚部７２の先端にベース部材１７がねじ又はスナップフィット等の適宜の方法で固定されている。取付板７１において、送電部１０と反対側の面には、コイルばね９０の一端側をガイドする円環状のガイド部材８２が取り付けられている。 The mounting plate 71 is formed by bending a metal plate. A plurality of (for example, four) L-shaped legs 72 protruding toward the power transmission unit 10 are provided on the surface of the mounting plate 71 facing the power transmission unit 10 , and the base member 17 is screwed to the tip of each leg 72 . Alternatively, it is fixed by an appropriate method such as snap fit. An annular guide member 82 that guides one end side of the coil spring 90 is attached to the surface of the mounting plate 71 opposite to the power transmission section 10 .

ジョイント部材７３は、図２に示すように、一端側にボール部７５が設けられたシャフト７４と、ボール部７５を任意の方向に回転可能な状態で支持するソケット７６とを備えている。シャフト７４におけるボール部７５と反対側の端部は、取付板７１において送電部１０の中心位置に対応する部位に固定されている。 As shown in FIG. 2, the joint member 73 includes a shaft 74 having a ball portion 75 at one end, and a socket 76 that supports the ball portion 75 so as to be rotatable in any direction. An end portion of shaft 74 opposite to ball portion 75 is fixed to a portion of mounting plate 71 corresponding to the central position of power transmission section 10 .

スライド部材７７は、送電部１０と受電部２０とが対向する対向方向（矢印ＤＲ１又はＤＲ２の方向）に沿って延びる円筒状に形成されている。このスライド部材７７にはソケット７６が固定されている。フレーム５５には、対向方向（矢印ＤＲ１又はＤＲ２の方向）においてスライド部材７７を変位可能な状態で支持するホルダ部材７９が取り付けられている。ホルダ部材７９には、このホルダ部材７９を対向方向において貫通する貫通孔８０が形成されており、この貫通孔８０にはスライド部材７７の一端側（左側）が挿入されている。スライド部材７７の他端側には貫通孔８０の内径よりも大きな外径を有する大径部７８が設けられている。また、ホルダ部材７９の一端側には貫通孔８０の内径よりも外径が大きい円板状の抜け止板８１が取り付けられている。これにより、スライド部材７７は、大径部７８又は抜け止板８１がホルダ部材７９における貫通孔８０の周縁部分と当接することによって、その移動範囲が制限されている。 Slide member 77 is formed in a cylindrical shape extending along the facing direction (direction of arrow DR1 or DR2) in which power transmission unit 10 and power reception unit 20 face each other. A socket 76 is fixed to the slide member 77 . A holder member 79 is attached to the frame 55 to support the slide member 77 in a displaceable state in the opposing direction (the direction of the arrow DR1 or DR2). A through hole 80 is formed in the holder member 79 so as to pass through the holder member 79 in the facing direction, and one end side (left side) of the slide member 77 is inserted into the through hole 80 . A large diameter portion 78 having an outer diameter larger than the inner diameter of the through hole 80 is provided on the other end side of the slide member 77 . A disc-shaped retainer plate 81 having an outer diameter larger than the inner diameter of the through hole 80 is attached to one end of the holder member 79 . As a result, the large diameter portion 78 or the retainer plate 81 of the slide member 77 abuts against the periphery of the through hole 80 in the holder member 79 , thereby restricting the movement range of the slide member 77 .

ここにおいて、送電部１０は取付板７１に取り付けられており、送電部１０にはジョイント部材７３のシャフト７４が固定されている。ジョイント部材７３のソケット７６はスライド部材７７に固定されており、スライド部材７７は、フレーム５５に固定されたホルダ部材７９に対して、対向方向において変位可能な状態で取り付けられている。そして、ホルダ部材７９と取付板７１との間にはコイルばね９０が取り付けられており、コイルばね９０の弾性力で取付板７１がホルダ部材７９から離れる方向に押されることによって、送電部１０がホルダ部材７９から離れる方向に押されている。したがって、電動移動体３の前輪３１０が車輪載置部５２に置かれた状態では、コイルばね９０の弾性力によって、送電部１０の第１面１２と受電部２０の第２面２２とが互いに押し付けられた状態で接触している。 Here, power transmission section 10 is attached to mounting plate 71 , and shaft 74 of joint member 73 is fixed to power transmission section 10 . The socket 76 of the joint member 73 is fixed to a slide member 77, and the slide member 77 is attached to a holder member 79 fixed to the frame 55 so as to be displaceable in the opposing direction. A coil spring 90 is attached between the holder member 79 and the mounting plate 71 , and the elastic force of the coil spring 90 pushes the mounting plate 71 away from the holder member 79 , thereby causing the power transmission unit 10 to move. It is pushed away from the holder member 79 . Therefore, when the front wheel 310 of the electric vehicle 3 is placed on the wheel rest portion 52 , the elastic force of the coil spring 90 causes the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception unit 20 to move toward each other. They are in contact while being pressed.

本実施形態では、保持部であるコイルばね９０が第１面１２と第２面２２とを弾性力で押し付けている。保持部であるコイルばね９０が、第１面１２と第２面２２とを弾性力で押し付けることによって、送電部１０と受電部２０との相対的な位置のずれを低減できる。さらに言えば送電部１０が対向方向（矢印ＤＲ１又は矢印ＤＲ２の方向）において変位可能であり、保持部は、弾性力によって送電部１０を受電部２０側に押し付ける弾性部材（コイルばね９０）を含んでいる。したがって、電動移動体３に人等の物体がぶつかったり、電動移動体３に風が当たったりすることで、前輪３１０の位置が動いたとしても、第１面１２と第２面２２との間に隙間ができにくくなり、第１面１２と第２面２２との接触位置がずれにくくなる。よって、送電部１０と受電部２０との間で電力を伝達する伝達効率の低下を抑制することができる。 In this embodiment, the coil spring 90, which is the holding portion, presses the first surface 12 and the second surface 22 with an elastic force. Coil spring 90 as a holding portion presses first surface 12 and second surface 22 with an elastic force, thereby reducing relative positional deviation between power transmitting portion 10 and power receiving portion 20 . Furthermore, the power transmission unit 10 can be displaced in the opposing direction (the direction of the arrow DR1 or the arrow DR2), and the holding unit includes an elastic member (coil spring 90) that presses the power transmission unit 10 toward the power reception unit 20 with elastic force. I'm in. Therefore, even if an object such as a person collides with the electric vehicle 3 or the wind hits the electric vehicle 3 and the position of the front wheel 310 moves, the distance between the first surface 12 and the second surface 22 will be reduced. A gap is less likely to form between the two surfaces, and the contact position between the first surface 12 and the second surface 22 is less likely to shift. Therefore, it is possible to suppress a decrease in the efficiency of power transmission between power transmission unit 10 and power reception unit 20 .

また、送電部１０が取り付けられる取付板７１はジョイント部材７３を介してスライド部材７７に固定されているので、送電部１０を支持点ＳＰ１を中心として任意の方向に回転させることができる。ここで、ジョイント部材７３が支持点ＳＰ１を中心として任意の方向に送電部１０を回転可能であるとは、支持点ＳＰ１を通りかつシャフト７４に沿って延びる線分と直交する平面内で送電部１０を任意の方向（３６０度全ての方向）に移動可能なことをいう。例えば、Ｘ－Ｙ平面においてはジョイント部材７３は送電部１０を上下方向（図２の矢印ＤＲ３又は矢印ＤＲ４に示す方向）に回転させることができる。なお、図２に示す送電部１０の回転方向はＸ－Ｙ平面に限った場合の回転方向であり、実際には任意の方向に回転可能である。 Moreover, since the mounting plate 71 to which the power transmission section 10 is attached is fixed to the slide member 77 via the joint member 73, the power transmission section 10 can be rotated in any direction around the support point SP1. Here, the fact that the joint member 73 can rotate the power transmission section 10 in any direction about the support point SP1 means that the power transmission section 10 is rotated in a plane passing through the support point SP1 and perpendicular to the line segment extending along the shaft 74 . 10 can be moved in any direction (all directions of 360 degrees). For example, on the XY plane, joint member 73 can rotate power transmission section 10 in the vertical direction (direction indicated by arrow DR3 or arrow DR4 in FIG. 2). Note that the rotation direction of the power transmission unit 10 shown in FIG. 2 is the rotation direction limited to the XY plane, and can actually rotate in any direction.

したがって、電動移動体３に人等がぶつかったり、電動移動体３に風が当たったりすることで、前輪３１０の向きが変わったとしても、第２面２２の向きに合わせて、第１面１２の向きを変えることができ、第１面１２と第２面２２との間に隙間ができにくくなる。よって、送電部１０と受電部２０との間で電力を伝達する伝達効率の低下を抑制することができる。 Therefore, even if the direction of the front wheels 310 changes due to a person or the like hitting the electric vehicle 3 or the wind blowing against the electric vehicle 3, the first surface 12 can be adjusted to match the direction of the second surface 22 . can be changed, and a gap is less likely to form between the first surface 12 and the second surface 22.例文帳に追加Therefore, it is possible to suppress a decrease in the efficiency of power transmission between power transmission unit 10 and power reception unit 20 .

なお、支持部７０は、送電部１０を支持点ＳＰ１を中心に全周方向で回転自在に支持しているため、送電部１０の重みで送電部１０の第１面１２が下側を向く可能性がある。そこで、非接触給電装置１は、送電部１０の第１面１２の向きを所定の範囲に制限するための制限部材を備えている。 Since the support portion 70 supports the power transmission portion 10 so as to be rotatable around the support point SP1 in all circumferential directions, the weight of the power transmission portion 10 can cause the first surface 12 of the power transmission portion 10 to face downward. have a nature. Therefore, the contactless power supply device 1 includes a limiting member for limiting the orientation of the first surface 12 of the power transmission section 10 within a predetermined range.

制限部材は、送電部１０と本体５０との間に配置されるばね部材９１を含む。ばね部材９１は例えばコイルばねからなる。ばね部材９１の一端は、送電部１０に固定された取付板７１に保持され、ばね部材９１の他端は、本体５０を構成するフレーム５５に固定されたホルダ部材７９に保持されている。本実施形態では、前後方向において、２つのばね部材９１がジョイント部材７３を間にして対称な位置に配置されている。これにより、ばね部材９１は送電部１０と本体５０との間に配置され、取付板７１をホルダ部材７９から離れる向きに押すことで、送電部１０の第１面１２の向きを所定の範囲に制限している。ばね部材９１は、例えば第１面１２の法線が水平面となす角度を数度以下の範囲に制限している。なお、本実施形態ではばね部材９１が支持点ＳＰ１よりも下側に配置されているが、制限部材は、支持点ＳＰ１よりも上側に配置され、取付板７１をホルダ部材７９側に引っ張る向きの弾性力を取付板７１に加えるばね部材で構成されてもよい。 The limiting member includes a spring member 91 arranged between power transmission section 10 and main body 50 . The spring member 91 consists of a coil spring, for example. One end of the spring member 91 is held by a mounting plate 71 fixed to the power transmission section 10 , and the other end of the spring member 91 is held by a holder member 79 fixed to the frame 55 forming the main body 50 . In this embodiment, two spring members 91 are arranged at symmetrical positions with the joint member 73 interposed therebetween in the front-rear direction. As a result, the spring member 91 is arranged between the power transmission section 10 and the main body 50, and by pushing the mounting plate 71 away from the holder member 79, the orientation of the first surface 12 of the power transmission section 10 is adjusted within a predetermined range. restricted. The spring member 91 limits, for example, the angle between the normal line of the first surface 12 and the horizontal plane to several degrees or less. In this embodiment, the spring member 91 is arranged below the support point SP1, but the restricting member is arranged above the support point SP1 and is oriented in a direction to pull the mounting plate 71 toward the holder member 79 side. It may be composed of a spring member that applies an elastic force to the mounting plate 71 .

また、本実施形態では、制限部材が紐状部材９２を更に含んでいる。紐状部材９２は、支持点ＳＰ１よりも上側で、本体５０と送電部１０との間に取り付けられている。紐状部材９２は、合成繊維又は天然繊維により紐状に形成されている。具体的には、紐状部材９２の一端は、送電部１０に固定された取付板７１において、支持点ＳＰ１よりも上側の部位に固定されている。紐状部材９２の他端は、本体５０を構成するフレーム５５に固定されたホルダ部材７９において、支持点ＳＰ１よりも上側の部位に固定されている。これにより、紐状部材９２の一端が固定された取付板７１の部位と、紐状部材９２の他端が固定されたホルダ部材７９の部位との間隔が紐状部材９２の長さ以下に制限されるので、送電部１０の第１面１２の傾きを所定の範囲に制限することができる。 Moreover, in this embodiment, the restricting member further includes a cord-like member 92 . The string member 92 is attached between the main body 50 and the power transmission section 10 above the support point SP1. The string-like member 92 is formed in a string-like shape from synthetic fibers or natural fibers. Specifically, one end of the string-like member 92 is fixed to a portion of the mounting plate 71 fixed to the power transmission section 10 above the support point SP1. The other end of the string-like member 92 is fixed to a portion above the support point SP1 in the holder member 79 fixed to the frame 55 forming the main body 50 . As a result, the distance between the portion of the mounting plate 71 to which one end of the string-like member 92 is fixed and the portion of the holder member 79 to which the other end of the string-like member 92 is fixed is limited to the length of the string-like member 92 or less. Therefore, the inclination of the first surface 12 of the power transmission section 10 can be limited within a predetermined range.

なお、非接触給電装置１が、制限部材としてばね部材９１と紐状部材９２の両方を備えることは必須ではなく、制限部材はばね部材９１及び紐状部材９２のいずれか一方のみでもよい。 It should be noted that it is not essential that the contactless power supply device 1 includes both the spring member 91 and the string-like member 92 as limiting members, and the limiting member may be either the spring member 91 or the string-like member 92 .

（２．５）動作
次に、本実施形態の非接触給電システムＡ１において、非接触給電装置１から電動移動体３に保持された非接触受電装置２に給電する動作について説明する。 (2.5) Operation Next, the operation of supplying power from the contactless power supply device 1 to the contactless power receiving device 2 held by the electric vehicle 3 in the contactless power supply system A1 of the present embodiment will be described.

図１１及び図１２に示すように、電動移動体３のユーザは、電動移動体３を駐車する際に、電動移動体３を押して、電動移動体３の前輪３１０を非接触給電装置１の車輪載置部５２に設けられたガイド部５７内に移動させる。このとき、前輪３１０はガイド部５７の傾斜部５９に沿って移動し、傾斜部５９の頂上付近（図１２の位置Ｐ１）に到達するまでの間に、電動移動体３に保持された受電部２０の受電側カバー２３が、非接触給電装置１に保持された送電部１０の送電側カバー１３と接触する。ユーザが電動移動体３を更に押し、前輪３１０が傾斜部５９の頂上付近を乗り越えて保持溝５８に嵌まり込むと（図１２の位置Ｐ２）、前輪３１０の車軸３１１の延長線Ｌ１上で送電部１０の第１面１２と受電部２０の第２面２２とが対向している状態となる。この状態では、受電部２０によって送電部１０が支柱部５３の内側に入り込む方向（図３の矢印ＤＲ５の方向）に押されるので、コイルばね９０の弾性力によって第１面１２と第２面２２とが互いに押し付けられた状態で接触する。第１面１２と第２面２２とが対向する状態になると、送電部１０から受電部２０に対して電磁誘導方式で非接触給電が行われ、電動移動体３の充電回路３２１が蓄電池３２０を充電する。蓄電池３２０が満充電になると、充電回路３２１は蓄電池３２０の充電を停止するので、蓄電池３２０の過充電が抑制される。 As shown in FIGS. 11 and 12 , when the electric vehicle 3 is parked, the user of the electric vehicle 3 pushes the electric vehicle 3 to move the front wheels 310 of the electric vehicle 3 to the wheels of the contactless power supply device 1 . It is moved into the guide portion 57 provided in the mounting portion 52 . At this time, the front wheel 310 moves along the inclined portion 59 of the guide portion 57 and reaches the vicinity of the top of the inclined portion 59 (position P1 in FIG. 12). A power receiving side cover 23 of 20 contacts the power transmitting side cover 13 of the power transmitting section 10 held in the contactless power supply device 1 . When the user pushes the electric vehicle 3 further and the front wheels 310 get over the vicinity of the top of the inclined portion 59 and fit into the holding grooves 58 (position P2 in FIG. 12), power is transmitted on the extension line L1 of the axle 311 of the front wheels 310. The first surface 12 of the unit 10 and the second surface 22 of the power receiving unit 20 face each other. In this state, the power receiving unit 20 pushes the power transmitting unit 10 in the direction in which the power transmitting unit 10 enters the inside of the supporting column 53 (the direction of the arrow DR5 in FIG. 3). contact while being pressed against each other. When the first surface 12 and the second surface 22 face each other, contactless power supply is performed from the power transmitting unit 10 to the power receiving unit 20 by electromagnetic induction, and the charging circuit 321 of the electric vehicle 3 charges the storage battery 320. to charge. Since the charging circuit 321 stops charging the storage battery 320 when the storage battery 320 is fully charged, overcharging of the storage battery 320 is suppressed.

ここで、送電部１０は、支持部７０により支持点ＳＰ１を中心として回転自在に保持されている。また、支持部７０は対向方向（矢印ＤＲ１又はＤＲ２の方向）において変位可能であり、保持部であるコイルばね９０によって第１面１２と第２面２２とを互いに押し付けられた状態で保持している。したがって、前輪３１０が傾くことによって受電部２０の第２面２２の向きが変化したり、第２面２２が左右方向において多少ずれたりしても、第１面１２と第２面２２とを確実に接触させることができる。したがって、送電部１０が備える送電コイルと、受電部２０が備える受電コイルとの位置ずれを抑制でき、送電部１０と受電部２０との間での電力の伝達効率の低下を抑制可能な非接触給電システムＡ１を提供することができる。 Here, the power transmission section 10 is held by the support section 70 so as to be rotatable about the support point SP1. Further, the support portion 70 is displaceable in the opposite direction (the direction of the arrow DR1 or DR2), and holds the first surface 12 and the second surface 22 in a state of being pressed against each other by the coil spring 90 as the holding portion. there is Therefore, even if the orientation of the second surface 22 of the power receiving unit 20 changes due to the inclination of the front wheel 310 or the second surface 22 shifts to some extent in the left-right direction, the first surface 12 and the second surface 22 can be reliably secured. can be contacted. Therefore, it is possible to suppress the positional deviation between the power transmission coil provided in the power transmission unit 10 and the power reception coil provided in the power reception unit 20, and the non-contact device capable of suppressing a decrease in power transmission efficiency between the power transmission unit 10 and the power reception unit 20. A power supply system A1 can be provided.

なお、前輪３１０が車輪載置部５２に置かれた電動移動体３を、前輪３１０が保持溝５８から傾斜部５９側へ移動する方向にユーザが引っ張ると、電動移動体３を非接触給電装置１から取り出すことができるので、ユーザは電動移動体３を利用することができる。 Note that when the user pulls the electric vehicle 3 with the front wheels 310 placed on the wheel mounting portion 52 in the direction in which the front wheels 310 move from the holding grooves 58 toward the inclined portion 59, the electric vehicle 3 moves toward the contactless power supply device. 1, the user can use the electric vehicle 3.

このように、非接触給電装置１の送電部１０は、電動移動体３に設けられた受電部２０に電線等を介さずに非接触給電を行っているので、電動移動体３を非接触給電装置１の車輪載置部５２に載せるだけで、電動移動体３の蓄電池３２０を簡単に充電できる。また、電動移動体３を非接触給電装置１から取り出す際も、電動移動体３と非接触給電装置１とが電線等で繋がっていないので、電動移動体３を車輪載置部５２から引き出すだけでよく、使い勝手が向上するという利点がある。 As described above, the power transmission unit 10 of the non-contact power supply device 1 performs non-contact power supply to the power reception unit 20 provided in the electric vehicle 3 without using wires or the like. The storage battery 320 of the electric vehicle 3 can be easily charged simply by placing it on the wheel mounting portion 52 of the device 1 .
