Description

The present invention relates to an in-vehicle device such as an in-vehicle camera attached to a vehicle.

Among the in-vehicle devices, the in-vehicle camera is installed at the rear of the vehicle, for example, to confirm the safety of the rear side of the vehicle. There are the following methods for fixing the in-vehicle camera to the vehicle. This will be described with reference to the drawings showing the procedure for attaching the in-vehicle camera of FIGS. 8A to 8C to the vehicle. A hole 810 is provided at the rear of the vehicle, while a leaf spring 710 is provided on the side surface of the housing 700 of the vehicle-mounted camera 10, and a head 730 which is a portion of the housing 700 of the vehicle-mounted camera 10 where a lens 720 for capturing light is located. Is formed in a circular shape larger than the hole 810 of the vehicle. The leaf spring 710 is bent at the center in the longitudinal direction to form a mountain shape. The leaf spring 710 is arranged so that one end 710a of the leaf spring 710 in the longitudinal direction is located in the vicinity of the head 730. One end 710a of the leaf spring 710 near the head 730 is a free end, and the other end 710b is fixed to the housing 700. By inserting the in-vehicle camera 10 into the hole 810 of the vehicle from the outside of the vehicle, the leaf spring 710 completely enters the inside of the vehicle. Then, the leaf spring 710 opens in a chevron shape inside the vehicle, one end 710a of the leaf spring 710 comes into contact with the body of the vehicle from the inside of the vehicle, and the head 730 of the housing 700 of the in-vehicle camera 10 is also of the vehicle. By contacting the body from the outside of the vehicle, the in-vehicle camera 10 sandwiches the body of the vehicle in the front-rear direction and is fixed to the vehicle. (See Patent Document 1)

However, in this method, since the vehicle-mounted camera 10 merely sandwiches the vehicle body between the leaf spring 710 and the head 730 of the housing 700 of the vehicle-mounted camera 10, it is vulnerable to vibration and the like, and when the vehicle-mounted camera 10 is subjected to vehicle vibration. , The in-vehicle camera 10 may come off from the hole 810.

Therefore, there are the following methods as a method for solving this problem. The vehicle is provided with a screw hole for passing a screw and a hole for inserting an in-vehicle camera. A bracket for attaching the in-vehicle camera to the vehicle is provided. The bracket is provided with a threaded hole on the inside. After attaching the in-vehicle camera to this bracket, insert the in-vehicle camera into the hole from the inside of the vehicle, bring it into contact with the vehicle, and screw the screw from the outside of the vehicle through the screw through hole of the vehicle into the screw hole in the bracket. By fixing with screws, the in-vehicle camera is fixed to the vehicle with screws. However, when tightening the screws, it was necessary to hold the in-vehicle camera from the inside of the vehicle so that the operator would not move, or temporarily fix the in-vehicle camera to the vehicle so that it would not move. Therefore, engaging portions having claw portions (first claw portions) for temporary fixing are formed on both side surfaces of the bracket in the left-right direction. Each engaging portion is inserted into a hole in the vehicle from the inside to the outside of the vehicle, and each claw is locked to the peripheral edge of the hole in the vehicle to be temporarily fixed. After temporarily fixing, the bracket is fixed by screwing the vehicle and the bracket. In this way, the claws are locked to the periphery of the holes simply by inserting the engaging portion on the bracket into the hole in the vehicle, so the bracket does not move with respect to the vehicle when the screws are tightened. It can be temporarily fixed like this.

On the other hand, an on-board camera may have an exterior cover attached to a bracket in order to improve the design such as hiding a hole in the vehicle. In order to attach the exterior cover, it is conceivable to provide the engaging portion on the bracket with a second claw portion for locking the exterior cover together with the first claw portion described above. Therefore, as shown in FIG. 9, the tips of the engaging portions 210a and 210b are extended, and the second claw portions 211c and 211d for locking the exterior cover 300 are provided on the newly formed tips. The exterior cover 300 can be attached to the bracket 200 by locking the second claw portions 211c and 211d to the pair of locking portions 320a and 320b on the exterior cover 300, respectively.

Japanese Unexamined Patent Publication No. 2004-232787

However, this method has a problem that the engaging portions 210a and 210b become long and the strength of the engaging portions 210a and 210b becomes weak. Further, when the engaging portions 210a and 210b are greatly bent when the in-vehicle camera 10 is fixed to the vehicle, the distance L2 between the second claw portions 211c and 211d at the tips of the two engaging portions 210a and 210b is the second. The distance between the claw portions 211a and 211b may be narrower or wider than the distance L1. As shown in FIG. 10, when the distance L2 between the second claw portions 211c and 211d is narrowed (L2 <L1), this distance L2 is smaller than the distance L3 between the locking portions 320a and 320b of the exterior cover 300. Therefore, since the second claw portions 211c and 211d of the engaging portions 210a and 210b are located inside the locking portions 320a and 320b of the exterior cover 300, they cannot be locked and the exterior cover 300 can be attached to the bracket 200. There was a problem I couldn't do. On the other hand, as shown in FIG. 11, when the distance L2 between the second claw portions 211c and 211d is widened (L2> L1), this distance L2 is larger than the distance L3 between the locking portions 320a and 320b of the exterior cover 300. Since the second claw portions 211c and 211d of the engaging portions 210a and 210b are located outside the locking portions 320a and 320b of the exterior cover 300, they cannot be locked, and the exterior cover 300 is also bracketed 200. There was a problem that it could not be attached to.

Therefore, it is an object of the present invention to make it easy to attach the bracket to the vehicle and to make it easy to attach the exterior cover to the bracket after attaching the bracket to the vehicle.

In order to solve the above-mentioned problems, the in-vehicle device of the present invention is an in-vehicle device attached to a hole provided in a vehicle body, in which a housing in which parts are housed and a bracket attached to the housing are used. And an exterior cover that covers the front side of the housing and has a locking portion that is locked to the bracket, and the bracket has a claw portion that has a locking surface and a facing surface that faces the locking surface. An elastic member is arranged on the facing surface, and the locking surface of the claw portion sandwiches the body with the elastic member when the housing is inserted into the hole, and the locking portion of the exterior cover is the housing. By being inserted into the hole and the bracket being screwed to the body with a screw, a locking receiving portion is formed between the claw portion and the body, and the bracket is locked to the formed locking receiving portion. And.

According to the in-vehicle camera of the present invention, the bracket can be easily attached to the vehicle, and the exterior cover can be easily attached to the bracket after the bracket is attached to the vehicle.
