Description

Mounting base structure and method for inner rearview mirror Technical Field The invention relates to the technical field of automobile inner rearview mirrors, in particular to an inner rearview mirror mounting base structure and an inner rearview mirror mounting base method. Background The installation modes of the automobile inside rearview mirror at the present stage are mainly divided into two types. The first is to lock the inner rearview mirror directly by the screw to combine with the mounting base glued on the front windshield in advance, the second is to rely on the customized base mounting bracket to fix the bracket and the front top beam sheet metal structure of the automobile body, and then to complete the assembly of the inner rearview mirror by the screw. The two modes are all dependent on screw fastening, the traditional process not only prolongs the assembly time and increases the working procedures, and causes the waste of working hours, but also improves the material and labor cost of the production end due to the additional investment of connecting pieces and the complex assembly flow, and brings challenges to the management and control of the manufacturing cost of the whole automobile. In addition, the screw is required to be disassembled for maintaining the inner rearview mirror every time, the workload of maintenance personnel is increased by repeated disassembly and assembly, and the continuous mechanical abrasion of the base and the screw is caused, so that the structural strength and the service life of the component are affected. In the past, the base is very easy to loosen, screw is smooth to be threaded and other faults, and finally the whole set of base assembly or fastener has to be replaced, so that the overall cost is high.
