Description

Technical Field

[0001] The utility model relates to a rearview mirror, in particular to a device for adjusting the direction of the rearview mirror. Background Art

[0002] Rearview mirrors are widely used on various vehicles to facilitate drivers to observe the scene behind them and improve driving safety. At the same time, in order to accurately observe the scene behind them, the rearview mirrors also need to be adjusted to a certain angle to meet the needs of different groups of people. Existing rearview mirrors are installed on vehicles through mirror rods. The mirror rods are relatively fixed to the vehicle. The mirror housing with lenses can be rotated relative to the end of the mirror rod to form angle adjustment. However, the adjustment range of this adjustment structure is small, and the mirror housing can only be rotated around a fixed point. If a larger range of adjustment is required, the mirror rod must be removed and reinstalled on the vehicle at different angles. There are even many rearview mirrors whose mirror rods can only be installed on the vehicle in a fixed position and cannot be effectively adjusted, which affects the work of the rearview mirror and the driving safety of the driver.
