Description
Technical Field
[0001] The utility model relates to the technical field of rearview mirror structures, in particular to a substrate structure of an automobile rearview mirror. Background Art
[0002] The vehicle rearview mirror is a kind of auxiliary driving device installed on the car, mainly located on the left and right sides of the head of the car and the front of the interior of the car. The existence of these rearview mirrors is to help the driver expand the field of vision, so that he can observe the traffic conditions around the vehicle more comprehensively, reduce the risk of accidents, and ensure driving safety. Specifically, the exterior rearview mirror (also called side mirror or exterior rearview mirror) is usually installed on the driver's side and the co-pilot's side doors. Some models also install rearview mirrors (i.e. rearview wide-angle mirrors or convex mirrors) on the rear of both sides of the car body to further increase the breadth of the rear view. These rearview mirrors help the driver observe the traffic conditions behind and directly behind the vehicle through different mirror designs and installation angles, including the dynamics of other vehicles, pedestrians, bicycles and other road users. The interior rearview mirror is installed under the windshield to observe the traffic conditions directly behind the vehicle. The mirror surface of the interior rearview mirror is generally a flat mirror or a slightly convex mirror to provide a clear and distortion-free field of vision. In general, car rearview mirrors are one of the indispensable safety devices in cars. They play a vital role in helping drivers observe traffic conditions around the vehicle and make correct driving decisions.
[0003] In the prior art, a vehicle rearview mirror includes a mirror housing, a substrate, a lens and other components. When the rearview mirror is folded, it lacks a buffering function, which makes it easy to shake and make noise when flipping and folding. Therefore, we need to propose a substrate structure for a vehicle rearview mirror. Utility Model Content

[0026] See also Figure 1-3 , the utility model provides a technical solution:
[0027] A substrate structure of a rearview mirror for an automobile, comprising:
[0028] The main body 1 of the inner substrate of the rearview mirror; the main body 1 is fixed inside the mirror housing by fixing screws, the edge of the main body 1 is provided with a mounting hole 6 corresponding to the mounting of the fixing screws, the main body 1 is provided with a clamping portion 3 for clamping the lens support plate, and a clamping block 7 is provided at the clamping portion 3;
