Description

High reliability bracket mounting structure and rear-view mirror

Technical Field

The present disclosure relates to a vehicle rearview mirror, and more particularly to a bracket mounting structure of a rearview mirror and a rearview mirror.

Background

The automobile rearview mirrors are positioned on the left side and the right side of the head of the automobile and in front of the inside of the automobile. The automobile rearview mirror reflects the conditions of the rear, the side and the lower part of an automobile, so that a driver can indirectly see the conditions of the positions clearly, the automobile rearview mirror plays a role of a second eye, and the visual field range of the driver is expanded. With the development of science and technology, to installing the inside rear-view mirror of car, generally dispose the electric mirror surface, can possess dual function to this kind of rear-view mirror that disposes the electric mirror surface, both can be used to ordinary speculum, and the vehicle in reflection rear opens by force, can be used to electronic display again, through the image of electronic display screen display rear vehicle.

However, in the above two applications, the viewing angle requirements of the driver are different, and when the mirror is used as a general mirror, the mirror surface is required to be directed to the rear, and the viewing axis of the human eye is perpendicular to the mirror surface.

In order to facilitate installation of the angle adjusting mechanism, a fixing frame for installing the angle adjusting mechanism is generally fixed in the rear shell, and during assembly, the fixing frame needs to be installed in the rear shell first, and then the pivoting assembly is installed on the fixing frame, so that the assembly is complex, and the fixing frame is easily damaged or the installation failure of the pivoting assembly is easily caused due to dislocation during installation.

Therefore, referring to chinese patent CN201811608694, a support plate for mounting the pivot assembly is directly formed on the rear side surface of the rear housing, and during mounting, the support plate does not need to be assembled, because the pivot assembly usually needs to pull the whole rearview mirror under the action of external force, the support plate directly acting on the pivot assembly has extremely high strength requirement. On the one hand, the supporting plate in this patent document extends perpendicularly to the pivoting direction of the pivoting member to form a plate surface, and in the rearview mirror of this structure, the pivoting groove can only be provided very small and very shallow, so that the pivoting member can be easily separated from the pivoting groove under the action of external force, or the pivoting groove is worn to cause the pivoting member to fall off from the pivoting groove after long-term use. On the other hand, the pivot slot must be formed in the middle area of the whole supporting plate, and has a certain distance with both sides of the rear shell, so that the pivot seat of the pivot assembly must be very small, and when the pivot seat is pulled by external force, the pivot seat is more laborious, and the rear shell of the rearview mirror is difficult to be miniaturized, and occupies a large space.

Therefore, a rearview mirror structure capable of solving the above problems is urgently needed.
