[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiring structure for a vehicle mirror.

[0002]

[Prior art]

 One type of vehicle mirror is a vehicle mirror that includes a stay rotatably supported horizontally on a base that is mounted on the vehicle body and a mirror that is mounted on the upper end of the stay and is located outside the vehicle body. . In the vehicle mirror, the stay can be rotated horizontally by a predetermined or more rotational force from the outside, or can be rotated by driving an electric motor provided on the base to change the position of the mirror. Is. As another type of vehicle mirror, an electric motor is installed inside the mirror provided at the upper end of the stay fixed to the vehicle body, and the direction in which the mirror surface of the mirror faces can be changed by driving the motor. There is a vehicle mirror.

[0003]

[Problems to be solved by the device]

 By the way, in constructing a vehicle mirror in which the stay can be rotated and the facing direction of the mirror surface can be changed in the vehicle mirror, routing of the wiring for the electric motor provided inside the mirror becomes a problem. Become. That is, in the vehicle mirror, when the stay rotates, the mirror rotates integrally with the stay, and the wiring for the electric motor follows the mirror and moves. In this case, it is necessary to allow a sufficient length for the wiring to follow the mirror and move, but depending on how the wiring is handled, the wiring may be swung and stretched, loosened, or bent. As a result, the life of the wiring is shortened. Therefore, an object of the present invention is to address such a problem.

[0004]

[Means for Solving the Problems]

 The present invention comprises a stay rotatably supported in a horizontal direction on a base attached to a vehicle body, and a mirror attached to the upper end of the stay and located outside the vehicle body. This is a wiring structure for a vehicle mirror in which the facing direction of the mirror surface of the mirror can be changed by driving, and the stay is formed into a tubular shape, and the wiring for the electric motor is inserted through the inside of the stay. The wire is extended to the outside in conformity with the center axis of rotation of the wire, and the vicinity of the extended portion of the wire is fixed to the base side.

[0005]

[Operation and effect of the device]

 In the wiring arrangement structure having such a configuration, when the stay rotates, the mirror and the wiring rotate together with the stay. In this case, the wiring is twisted on the rotation center axis of the stay, but in the routing structure, it is not necessary to allow the wiring to have a sufficient length, and the wiring is not swung and stretched, loosened, or bent. Therefore, the life of the wiring can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a vehicle mirror according to the present invention. As shown in FIG. 5, the vehicle mirror is arranged at a corner which is a front side portion of a large vehicle such as a bus. As shown in FIGS. 1 to 4, the box-shaped base 11 and stays are provided. 12, a stay driving mechanism 13, a mirror 14, a mirror driving mechanism 15, a lead wire 16 which is a wiring for the mirror, and the like.

The base 11 is attached to the front corner of the vehicle, and the stay drive mechanism 13 is housed therein. The rotary shaft 13a that constitutes the drive mechanism 13 has its upper end portion protruding from the upper portion of the base 11, and one end of the stay 12 is fixedly mounted on the rotary shaft 13a. An inner cover 17 is fixed to one end of the stay 12, and in this state, the stay 12 is fixed to the upper part of the base 11 and protrudes upward from one side opening of the outer cover 18 that covers the stay 12. The mirror 14 is attached to the other end of the stay 12, and the mirror driving mechanism 15 is housed inside the mirror.

In the stay driving mechanism 13, the driving force of the electric motor 13b constituting the mechanism 13 is transmitted to the rotary shaft 13a through each speed reducing means to rotate the stay 12 fixed on the rotary shaft 13a. The stay 12 can be rotated in the horizontal direction by an angle of about 180 degrees which is the range shown in FIG. Further, in the mirror drive mechanism 15, the mirror surface 14a can be tilted in the vertical direction about the center thereof by driving an electric motor that constitutes the mechanism 15.

Therefore, the stay 12 has a cylindrical shape and is provided with an opening 12a at an upper portion on one end side thereof, and the inner cover 17 covering the portion is also provided with an opening coaxially opening with the opening 12a. The part 17a is provided. Each of these openings 12a and 17a is located coaxially with the rotating shaft 13a. The lead wire 16 is inserted through the inside of the stay 12, one end of which is connected to the power source and the other end of which is connected to the electric motor of the mirror drive mechanism 15 and the opening 12 a of the stay 12 is provided. Also, it extends from the opening 17a of the inner cover 17 to the outside. The lead wire 16 is received by a clamp 11a provided on the upper end of the base 11 near the extending portion, and is fixed to the base 11 by an outer cover 18.

In the wiring arrangement structure having such a configuration, when the stay 12 rotates, the mirror 14 and the lead wire 16 rotate together with the stay 14. In this case, the lead wire 16 is twisted and rotated on the rotation center axis of the stay 12, but it is not necessary to allow the length of the lead wire 16 to have a margin in the routing structure, and the lead wire 16 is swung to extend and relax. , Not bent. Therefore, the life of the lead wire 12 can be improved.
