DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show an electric mirror device 30 for a vehicle according to an embodiment of the present invention (corresponding to claims 1 to 3).
In the electric mirror device for a vehicle 30 according to the present embodiment, the first leg portion 60 and the second leg portion 65 in which the housing 40 to which the mirror mounting stay 50 is attached is attached to the outside of the vehicle body 31 by fixing parts such as bolts. In addition, it can be temporarily fixed.
[0012]
The housing 40 includes an upper housing 41 and a lower housing 42, and forms a space portion 43 that accommodates a motor capable of rotating in the forward and reverse directions and a rotation driving member driven by the motor at a central portion, and both side portions of the space portion 43. The first holding part 44 and the second holding part 45 are formed.
The first holding part 44 inserts the first leg part 60, and the second holding part 45 is formed by a space in which the second leg part 65 can be inserted.
[0013]
A third leg 70 is fixed to the housing 40 in advance by a fixing component 71 such as a bolt.
A rotating shaft 46 of the rotation drive member protrudes from the upper housing 41 of the housing 40.
A mirror mounting stay 50 is rotatably attached to the pivot shaft 46.
[0014]
The mirror mounting stay 50 is bent in a U-shape, and a lower view mirror 51, a rear view mirror 52, a side view lower view mirror 53, and the like are attached to appropriate positions of the mirror mounting stay 50. In order to reduce the weight of the mirror mounting stay 50, a metal tube or a solid metal rod may be used.
A base portion 50a on the upper end side of the mirror mounting stay 50 is attached to a turning shaft 46 of a housing 40 that houses a motor capable of rotating in the forward and reverse directions and a rotation driving member driven by the motor. The lower end portion 50 b of the mirror mounting stay 50 is rotatably supported by the bracket 75 by the lower end support shaft 54. The bracket 75 is fixed to a member (for example, a pillar) outside the vehicle body 31.
[0015]
Next, the operation of the thus configured electric mirror device 30 for a vehicle according to the present embodiment will be described.
First, the first leg portion 60 and the second leg portion 65 are attached to the outside of the vehicle body 31 by fixing parts 61 and 66 such as bolts.
Here, since the first leg portion 60 and the second leg portion 65 are members that support the housing 40 from both sides, the first leg portion 60 and the second leg portion 65 are arranged to face each other so as to be located on both sides of the housing 40. Further, the third leg portion 70 is disposed so as to support one side of the housing 40 from below so as to be connected to the second leg portion 65 after assembly.
[0016]
At the same time, the bracket 75 is fixed to a member (for example, a pillar) outside the vehicle body 31.
Next, the third leg portion 70 is fixed to the outside of the vehicle body 31 with fixing parts 72 such as bolts.
Next, the base portion 50a on the upper end side of the mirror mounting stay 50 is attached to the turning shaft 46 of the housing 40 and fixed by a fastening member, so that the housing 40 and the mirror mounting stay 50 are integrated.
[0017]
Next, the housing 40 is moved in the direction of the first leg portion 60 and the second leg portion 65 previously attached to the outside of the vehicle body 31 by bolts or the like, and the first holding portion 44 and the second holding portion on both sides are moved. The first leg 60 and the second leg 65 are inserted into the part 45.
[0018]
Here, as shown in FIG. 2, when the first leg portion 60 and the second leg portion 65 reach the end portions of the first holding portion 44 and the second holding portion 45, the movement of the housing 40 is prevented, and the housing It can be confirmed that 40 is temporarily fixed at a predetermined position. Next, the first leg portion 60, the second leg portion 65, and the third leg portion 70 are fixed to the outside of the vehicle body 31 by fixing parts 62, 67, 72 such as bolts.
[0019]
Next, the lower end portion 50 b of the mirror mounting stay 50 is rotatably supported on the bracket 75 by the lower end support shaft 54.
As described above, when the electric mirror device 30 for a vehicle is fixed to the vehicle body 31, the first leg portion 60 and the second leg portion 65 are attached to the outside of the vehicle body 51, and the housing 40 and the mirror attachment stay 50 are attached. First, the first leg portion 60 and the second leg portion 65 are attached to the outside of the vehicle body 31, and the housing 40 with the mirror mounting stay 50 attached thereto is attached to the first leg portion. 60 and the second leg portion 65 can be temporarily fixed via the first holding portion 44 and the second holding portion 45.
[0020]
In this state, the harness of the vehicle electric mirror device 30 is attached, and thereafter, the housing 40 and the first leg 60, the second leg 65, and the third leg 70 are fixed.
As described above, according to the present embodiment, since the vehicle electric mirror device 30 is not directly fixed to the vehicle body 31 as in the prior art, the work of fixing the vehicle electric mirror device 30 to the vehicle body 31 is a heavy labor. Therefore, it is possible to perform a simple operation.
[0021]
In the above embodiment, the case where the third leg portion 70 is fixed in advance to the housing 40 has been described. However, the third leg portion 70 is fixed in advance to the vehicle body 31 in the same manner as the first leg portion 60 and the second leg portion 65. You can keep it.
[0022]
【The invention's effect】
According to the present invention, since the electric mirror device for a vehicle and the leg portion for attaching the electric mirror device for a vehicle to the vehicle body can be separated and temporarily fixed using the leg portion attached to the vehicle body, the vehicle This makes it easy to fix the electric mirror device to the vehicle body.
