[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device capable of displacing a target object in a wide angle in an arbitrary direction by remote control, for example, a mirror externally mounted on a vehicle, a surveillance camera, and a camera. The present invention relates to a remote control device for a device, which is attached with a device such as a lighting fixture and can be remotely operated with a simple operation for rotationally displacing the device in an arbitrary direction.

Especially since it is often used outdoors, it is inevitable that the entire structure is closed. For this reason, it is difficult to supply the lubricating oil to the drive unit including the gear that rotates rapidly. Therefore, for long-term use, overhauling must be done to replenish the lubricating oil.

In addition, since the shaft portion to which the operated device is attached has a cantilever structure due to the assembly structure, an unbalanced load becomes large in order to lengthen the swivel arm or to support a heavy device. Since the structure of the part is made strong, the whole structure becomes large, which is inconvenient. Further, the conventional remote control device rotates the target device (mirror, etc.) by the required angle as described above, and only elevates the device by the required angle at a point protruding by a certain length from the center of the rotation, and the range beyond that. There is a problem such as that it cannot be operated remotely.

The thrust of the clutch mechanism 22 is supported.

The elevation drive mechanism 15 is provided with a female screw 26a portion which is screwed at the base portion to the feed screw 24, a linear moving element 26 provided with a rack 27 at a portion protruding from the base portion in the axial direction, and the linear moving element. Child 26 rack 2
The support arm 35 of the above-mentioned mirror which is meshed with the mirror 7 is formed of a pinion 28 fixed to a base end shaft (support portion) 36 inserted into the main body casing 10. The linear moving element 26 is supported in the rotating sleeve 21 so that it can reciprocate only. Further, the base end shaft 36 of the support arm 35 to which the pinion 28 is attached is rotatably mounted by being sandwiched between the receiving seat ring 32 and the pressing ring 33 fixed to the outer peripheral portion of the main body casing 10 described above. The bearing 37 is supported by the support ring 31.

In the remote control device 1 of the present embodiment constructed as described above, the power supply lines (not shown) for the turning motor 13 and the elevation motor 20 are connected to the power source using the inside of the support 3, for example. Control panel 6 installed in the driver's seat of a car
The operation of starting and stopping can be performed by (see FIG. 1).

When, for example, the turning motor 13 is driven to rotate in the normal direction in the control panel 6, a female screw screwed by the rotation of the feed screw 16 attached to the turning motor 13.
17a is moved in the direction of arrow a in FIG.
The operation piece 18 screwed to the ball screw 17b is rotated in the clockwise direction by the movement of the ball screw 17b having a large lead provided in the front half portion of the linear motion body 17 including. Then, the rotary sleeve 21 connected through the operation piece 18 and the clutch mechanism 22 is rotated in the same direction, and the elevation drive mechanism 25 disposed in the rotary sleeve 21 and the support arm 35 of the mirror are moved. The base shaft 36 is rotated so as to be rotated by a required rotation angle within the range of the long hole 34 for rotation provided in the main body casing 10. Therefore, the rearview mirror 5 supported by the mirror support arm 35 is rotated. It should be noted that when the turning motor 13 is operated to rotate in the reverse direction, all of the above-described turning motion parts are rotated in the reverse direction.

When the turning drive mechanism 15 is operated by the turning motor 13 in the turning operation, the starting rotation of the turning motor 13 is performed by the feed screw 16 and the female screw 17 of the linear moving body 17.
Due to the threading relationship with a, the direction is converted to a linear motion, and at the same time, the screw pitch by the feed screw 16 is small, so the screw number mechanism reduces the speed. Then, the rectilinear force of the linear motion body 17 converted into the linear motion is converted into the rotational motion by the screwing of the ball screw 17b having a large screw lead and the female screw 18a portion of the operating piece 18, which is further converted. It is slowed down by this screw number mechanism,
The operation piece 18 is slightly rotated according to the amount of straight movement of the ball screw 17b, and the mirror support arm 35 is rotated as described above. In addition, the conversion of the linear motion body 17 into the rotational motion by the ball screw 17b and the operation piece 18 that is screwed with the linear motion body 17 is smooth because the frictional resistance is small because the ball screw mechanism is adopted in the screwed portion. Done.

When the elevation motor 20 is driven to rotate in the forward direction, for example, a female screw 26a is screwed by the rotation of the feed screw 24 attached to the output shaft 20 'of the elevation motor 20.
The linear moving element 26 including is moved in the backward direction (the direction of arrow b). Then, the pinion 28 meshing with the rack 27 provided on the linear moving element 26 is rotated to rotate the support arm 35 of the mirror counterclockwise in the figure, and the rearview mirror 5 mounted on the support arm 35 of the mirror is rotated. Is rotated in the depression direction. Therefore, when the elevation motor 20 is operated to rotate in the reverse direction, the movement of the linear moving element 26 is reversed by the reverse rotation of the feed screw 24, and the mirror support arm 35 is rotated in the elevation direction. These elevation operations can be performed without any problem even if they are performed simultaneously with the above-described turning drive operation.

In this way, the rearview mirror 5 mounted and supported on the mirror support arm 35 is swiveled and raised / lowered so that a wide field of view can be easily set at a position / angle desired by the driver. Even if an external force larger than a set value acts on the support arm 35 of the mirror from the outside, as described above, the turning sleeve in which the swing drive mechanism 15 and the base of the support arm 35 of the mirror are incorporated. Since a ball-latch type clutch mechanism 22 is provided between the clutch mechanism 22 and the ball 21, a plurality of balls 22
Only the side of the rotary sleeve 21 that receives an external force rotates at the contact position between b and the end surface of the rotary sleeve 21 and the turning drive mechanism 15 is kept safe without being damaged.

Next, a concrete example of the second embodiment of the present invention will be described with reference to FIGS. The remote control device 1A according to the second embodiment will be described as a device for operating the rearview mirror 5 as in the first embodiment. Further, the same structural parts as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

This remote control device 1A is the same in appearance as that of the above-mentioned embodiment, except that both ends of the main body casing 10A are attached to the supports 3 and 3 (see FIG. 1).
It is rotatably supported on bearings 11 and 11 via bearings 40 and 40. The support arm 35A of the mirror is rotatably supported at its base portion at the intermediate portion of the main body casing 10A so that it can be fully swung together with the main body casing 10A.

Inside the main body casing 10A, a turning motor 13 held by a supporting cylinder 12 fixedly connected to one mounting piece 11, and a turning motor 13 connected to the turning motor 13 on the same axis. The drive mechanism 15, the elevation motor 20 provided to face the position opposite to the turning motor 13, and the elevation drive mechanism 25 connected to the elevation motor 20 on the same axis.
And are provided.

Then, the operation piece 18 in the turning drive mechanism 15
A is fixed to the main body casing 10A by, for example, a knock pin 18b, and is screwed with a female screw 18a and a front half ball screw 17b of a linear moving body 17 which is screwed with a feed screw 16 which is rotationally driven by a turning motor 13. The ball screw 17b is linearly moved so as to be swung together with the main body casing 10A.

The ascending / descending motor 20 and the ascending / descending drive mechanism 25 are supported on the same axis by a holding cylinder 29 fixed to the main body casing 10A by, for example, a knock pin 29a. The elevation drive mechanism 25 has the same structure as that of the first embodiment. The support arm of the above-mentioned mirror
The base shaft 36 of 35 is supported by bearings 39, 39 on a support ring 38 fixed to the body casing 10A.
A pinion 28 that engages with a rack 27 provided on the linear moving element 26 is attached between 9 and 39.

In the remote controller 1A according to the second embodiment having the above-described structure, the feed screw 16 and the female screw 17a are actuated by driving the turning motor 13 as in the case of the first embodiment. If the linear motion body 17 moves, the ball screw 17b moves straight and the operation piece 1 moves.
8A is rotated. Then, the operation piece 18A is integrated with the main body casing 10A, and
OA is a bearing 40, which is a mounting support portion with the supports 3 and 3.
The operation piece is rotatably supported by 40.
18A and the main body casing 10A are simultaneously turned. Therefore, can rotate the support arm 35 time also the main body casing 10A of the mirror which is supported a base end shaft 36 parts by support ring 38 which attaches to the main casing 10A by bearings 39, 39 without any problem 360
° You can make all turns.

Further, the support arm 35 of the mirror can be raised or lowered at an arbitrary angle by driving the elevation motor 20 and screwing the feed screw 24 and the linear moving element 26 into engagement with the rack 27 and the pinion 28. it can. Therefore, by the above-described full turn and elevation operation, the rearview mirror 5 (see FIG. 1) attached to the mirror support arm 35 can obtain a wider field of view than in the case of the first embodiment. The turning and elevation operations can be performed by the control panel provided in the driver's seat, as in the case of the above-described embodiment.

Next, in addition to the above-described first and second embodiments, as shown in FIG. 7, the mirror support arm 35B is provided with a telescopic shaft 50 at the base thereof so that the main body casing 10
Alternatively, a function of expanding and contracting in the orthogonal direction with respect to the rotation center line of 10 A can be added. The expansion / contraction operation of the expansion / contraction shaft 50 is configured so that the expansion / contraction shaft 50 and the feed screw 53 having a small screw pitch directly connected to the output shaft of the expansion / contraction driving motor 55 provided therein can be operated.

The telescopic shaft 50 has a base shaft 51, which is a hollow shaft, and is rotatably supported in the main body casing 10 (10A) by plain bearings 54, 54 so that the base shaft 51 is not movable in the axial direction. A movable shaft 52 having a female screw 52a screwed onto the feed screw 53 is fitted so as to be slidable only in the axial direction, and a mirror support arm 35B is connected to the tip of the movable shaft 52. . Then, the extension / contraction drive motor 55
Is, for example, fitted and inserted in the rear end portion of the base shaft 51, and is rotatably provided together with the base shaft 51 by the elevation drive mechanism 25 described above. The base shaft 51 is integrally connected to the pinion 28 by a key. In addition, the main body casing 10 of the base shaft 51
A seal ring 56 is provided near the entrance of the insertion part for (10A).
It is designed to prevent rainwater and dust from entering from the outside. When the expansion shaft 50 is incorporated, the main casing 10 (10A) has an outer diameter larger than that of the above-mentioned types. Of course, if necessary, it is possible to make the shape having a large diameter only in the vicinity of the mounting portion of the support arm 35B of the mirror having the expansion / contraction axis 50.

The support arm 35B of the mirror having the telescopic shaft 50 having such a structure operates the telescopic drive motor 55 to move the movable shaft 52 in the forward direction via the female screw 52a screwed by the feed screw 53. And its movable axis 52
The support arm 35B of the mirror directly connected to is projected. Therefore, a mirror (not shown) attached to the support arm 35B of the mirror can be moved from a steady state to a distant position to change the field of view. Further, when the drive of the expansion / contraction drive motor 55 is rotated in the reverse direction, the movable shaft 52 is operated in the opposite manner to retract the support arm 35B of the mirror to reduce the protrusion amount. The movable shaft 52 is the base shaft.
Since it is provided so as not to rotate with respect to 51, the support arm 35B of the mirror does not rotate when performing such an expanding / contracting operation.

Even in the case where the expansion / contraction mechanism is provided, the normal turning and raising / lowering operations are the same as in the above-described embodiment. Therefore, the operation of raising and lowering the mirror (not shown) attached to the support arm 35B of the mirror is the downward drive mechanism.
By actuating 25 (see FIG. 2) and driving the base shaft 51 to which the pinion 28 is attached, the entire support shaft 35B of the mirror to which the telescopic shaft 50 is pivotally connected can be raised and lowered by the required rotation angle.

The remote control device for a mirror incorporating such a telescopic mechanism, when the driver wants to confirm another visual field beyond the normal rear visual field while the vehicle is traveling, the telescopic shaft 50 is set as described above. It can be operated to extend the support arm 35B of the mirror and perform both turning and elevation motions as required. Since it is dangerous to keep the mirror support arm 35B protruding beyond the specified length during traveling, it is possible to quickly return to the original posture by performing the reverse operation of the telescopic shaft 50 after performing the necessary confirmation. Since these operations can be easily performed with the operation switch at hand, even during driving while driving, safe driving can be performed without any trouble.

Although the remote control device for the rearview mirror of the automobile has been described above as an example, the remote control device 1 or 1A for the equipment of this embodiment sets the support structure of the main body casing 10 or 10A according to the application. In addition, by setting the device support arm according to the device to be used, devices such as TV cameras, sound wave transmitting / receiving devices, and lighting fixtures are attached, and the main body is supported and installed in a building or the like. As a result, it can be used as an operation device for security equipment or an operation device for equipment that requires remote control.
Therefore, it is needless to say that the present invention is not limited to the above-mentioned embodiment, and the structural shape of each part can be changed in accordance with the gist of the present invention.

It should be noted, the mirror in this embodiment the support arms 35, 35a, 35B is the corresponding to the device support arm according to the present invention.

According to the present invention, as described above, the drive units for operating the support arms of the equipment are reasonably grouped and housed inside the cylindrical body, and are driven at a low speed without using the reduction mechanism by the gear train. In addition, since it is configured such that the unbalanced load does not act on the drive main part, it is possible to obtain a device capable of stable drive operation and withstanding long-term use. Further, the structure of the drive unit is simplified, and refueling is facilitated, and maintenance management is convenient. In addition, although it was not possible to fully swivel the device in the past, it became possible to fully swivel the device by simplifying the structure, and it became more convenient by adding a function to extend and retract the support arm of the device, It has an advantage that the application can be expanded.
