Memory type mirror surface drive of automobile rearview mirror

Abstract

The invention discloses a memory type mirror surface drive of an automobile rearview mirror. A memory device which endows the memory function to the drive is arranged on the other side of the drive. The memory device is mainly composed of two sets of vertical transmission racks (5) arranged on the axis A and the axis B in a way of being diagonal relative to two lifting worms (4), transmission gears (7) meshed with the transmission racks (5), and potentiometers (8) used for feeding signals back to a circuit board (9), the potentiometers (8) and the transmission gears (7) are in coaxial connection, and the upper ends of the transmission racks (5) are meshed with the ball sockets of a mirror surface floating plate (3) through bulbs (5.1). The drive is provided with a damping and memory module, the operation is smooth, and the torque is uniform.

Description

technical field [0001] The invention relates to the field of automobile rear-view mirrors, in particular to a memory-type automobile rear-view mirror mirror surface driver. Background technique [0002] The rearview mirror of the car is an auto accessory for the driver to observe the running status of the vehicles and pedestrians behind while driving the car. The driver can observe the field of vision in a specific direction, which is convenient for safe driving. The river surface drivers on the market are divided into those with memory and those without memory, among which the memory mirror driver can adjust the best viewing angle of the rearview mirror according to the individual height and driving habits of each driver, and then proceed. Memory storage, after other people drive the vehicle or adjust the perspective of their own memory, the car owner can easily open their own memory storage, and the rearview mirror will return to the best setting state, which is favored b...

Problems solved by technology

[0003] But the problem is that almost all the existing automotive rearview mirror mirror driver products with memory function have a problem, that is, when the mirror driver is manually adjusted, the torque in the front, rear and left and right directions is not uniform, and the reason for this is because the memory module is designed in the The main drive rack directly driven by the motor is a straight rack or an arc rack or one end of the lifting worm, which results in a large torque in one direction and a small torque in the other direction. If the vehicle is driving on a country road, due to the ups and downs of the road surface , the car will also experience relatively serious vibration, and transmit the vibration to the driver installed in the rearview mirror. When this vibration happens in the direction of small torque, the driver may malfunction or be damaged at this time. The existing In the technology, the mirror driver of the rearview mirror has only two driving racks and the memory module is attached to one end of the two racks, which seriously affects the balance of the driver and the uniformity of the moment. The memory module is easily damaged and the memory function will be lost. If the resonance is serious, it may cause the drive rack of the mirror drive to break, and the entire drive will lose its adjustment function.
