[0002] At present, low-configuration or low-end models on the market are not equipped with the function of automatic folding of rearview mirrors, which causes certain inconveniences in use.

[0003] There are three common solutions to this problem. The first is to use a device that uses a central lock to control the unlocking and locking buttons in the car. This device is complicated to operate and prone to misoperation. The second is to add an independent folding control device, but it is necessary to damage the original vehicle trim panel for drilling and installation, which will affect the appearance. The third is a control device that integrates the rearview mirror control switch and the host module. It is necessary to re-open the mold based on the original vehicle's rearview mirror switch and structure. This device has a high degree of integration, but the original vehicle's rearview mirror switch needs to be replaced, which is costly. Utility Model Content
