Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a memory component of an automobile rearview mirror driver. Background Art
[0002] A rearview mirror is an automotive accessory that allows the driver to observe the status of vehicles and pedestrians behind them while driving. It is essential for safe driving. By adjusting the mirror's angle with the help of a mirror actuator, the driver can observe a specific direction of vision, facilitating safe driving. Mirror actuators on the market come in two types: with and without memory. Memory actuators are popular among consumers because they can adjust the rearview mirror's optimal viewing angle based on each driver's height and driving habits, then store the adjusted angle in memory. After someone else drives the vehicle or adjusts the angle to their preferred setting, the driver can easily activate the memory and the mirror will return to its optimal setting.
[0003] The memory assembly is provided with a dial, and the driver is provided with a rack. The transmission structure of the existing memory assembly includes a transmission gear meshing with the rack, and the transmission gear and the dial are transmitted through a double bevel gear. The transmission structure is relatively complex, which reduces the reliability of the transmission structure. Summary of the Invention
[0004] The embodiment of the present application provides a memory component of a car rearview mirror driver, in which the first rack and the first dial are transmitted only through the first gear column, and the second rack and the second dial are transmitted only through the second gear column, thereby reducing the transmission structure, improving the stability and reliability of the transmission, making the structure more compact, and reducing the space occupied by the memory component.
