Background

The automobile rearview mirror is an automobile accessory for a driver to observe running states of rear vehicles and pedestrians in the automobile running process, is necessary for safe driving, and can enable the driver to observe a visual field in a specific direction by adjusting the angle of the rearview mirror with the aid of the automobile rearview mirror surface driver, so that safe driving is facilitated. The river drivers in the market are divided into a memory type driver and a non-memory type driver, wherein the memory type mirror driver can adjust the optimal visual angle of the rearview mirror according to the difference between the individual height and the driving habit of each driver, then the memory storage is carried out, after other people drive the vehicle or are adjusted by other people to the memorized visual angle, the vehicle owner can very easily start the memory storage, and the rearview mirror can be restored to the optimal set state, so that the river driver is popular among consumers.

Chinese patent publication No. CN205737233U discloses an adjusting mechanism for a rear-view device of a motor vehicle, which adjusts an angle of the rear-view device by rotating a rear-view element support around a first pivot axis relative to a base frame through the adjusting mechanism, generates an electric signal indicating a pivoting angle between the base frame and the rear-view element support through a potentiometer, thereby implementing a memory, and employs a non-rotationally symmetric input gear so that a rotational position of a slider or a sliding resistor indirectly rotationally coupled to the input gear can be observed before assembling the adjusting mechanism by observing a rotational position of the asymmetric input gear. Thus, the potentiometer can be easily brought to a predetermined rotational position before the base of the potentiometer is securely attached to the first sub-assembly. However, the non-rotational-symmetry input gear is a non-standard part, so that the forming difficulty is high during manufacturing, the manufacturing cost is high, and the connector is arranged on the non-rotational-symmetry input gear and connected or fixed to the shaft through the connector, so that the manufacturing and assembling are complex.
