Exterior rearview mirror mounting bracket and mounting structure thereof

Abstract

The invention provides an exterior rearview mirror mounting bracket with good rigidity and strength and a mounting structure thereof. The exterior rearview mirror mounting bracket and the mounting structure thereof are used for arranging a rearview mirror at the upper left corner (lock side) of an exterior plate and improving the stability of the exterior rearview mirror. The exterior rearview mirror mounting bracket comprises a platy main body. Welding faces are arranged on the periphery of the main body, a mounting area used for fixing the exterior rearview mirror is arranged in the middle of the main body, and the height difference is formed between the mounting area and the welding faces, so that the exterior rearview mirror mounting bracket forms an open-box-shaped structure. The mounting structure of the exterior rearview mirror adopts the exterior rearview mirror mounting bracket, and the key lies in that the exterior rearview mirror mounting bracket is mounted on the side, facing the car interior, of a front side door exterior plate of a car; the welding faces of the exterior rearview mirror mounting bracket are welded and fixed to a door interior plate, an upper hinge reinforcing plate and a window frame exterior plate reinforcing plate correspondingly; and a cavity is formed between the mounting area of the exterior rearview mirror mounting bracket and the window frame exterior plate reinforcing plate of a side door.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a mounting bracket for an exterior rearview mirror and a mounting structure thereof. Background technique [0002] The exterior rearview mirror is one of the essential subsystems of the car, and it is a tool for the driver to directly obtain external information such as the rear and side of the car while sitting in the cab seat. The exterior rearview mirror is connected to the side door by means of a mounting bracket. During driving, if the modal rigidity and strength of the exterior rearview mirror mounting bracket are insufficient, it may cause the exterior rearview mirror to vibrate, making it difficult to see the rear and sides clearly. Further external information may lead to cracking, affect the normal use of the rearview mirror, and pose a safety hazard.

Problems solved by technology

The exterior rearview mirror is connected to the side door by means of a mounting bracket. During driving, if the modal rigidity and strength of the exterior rearview mirror mounting bracket are insufficient, it may cause the exterior rearview mirror to vibrate, making it difficult to see the rear and sides clearly. Further external information may lead to cracking, affect the normal use of the rearview mirror, and pose a safety hazard

[0003] At present, the mainstream models in the market place the exterior rearview mirror at the end of the guide rail of the lock side window frame. This position usually has small space restrictions, and the rigidity and local mode of the installation point are relatively easy to meet the requirements.

But for the sake of aesthetics, some cars arrange the rearview mirror at the upper left corner of the outer panel (lock side). For this design, since the glass front guide rail is arranged at this position, in order not to block the glass from sliding up and down, the outside rearview mirror installation bracket It must be designed in the form of a cantilever, and the support in the form of a cantilever is usually very weak in stiffness and stability, which brings great difficulty to the early design. If the design is not reasonable, it will be difficult to achieve the stiffness of the installation point and the local mode According to the requirements, there may be vibration problems during use, which may further cause cracking, affect the normal use of the rearview mirror, and pose a great safety hazard
