[0002] As an important part of the automotive accessories field, adjustable rearview mirrors have a long history of technological development. Early rearview mirrors mainly relied on manual adjustment, changing the angle of the lens by rotating or sliding to meet the driver's different needs for vision. With the advancement of technology, electric adjustable rearview mirrors have gradually become popular, and the automatic adjustment of the lens is achieved through motor drive, which greatly improves the convenience and accuracy of adjustment. Most of the existing adjustable rearview mirrors only have basic adjustment functions and lack intelligent characteristics. The field of view of traditional rearview mirrors is subject to certain limitations, especially when observing vehicles on the side and rear. There may be blind spots, which may cause the driver to fail to detect the vehicle on the side and rear in time when changing lanes or overtaking, increasing the risk of accidents. In rainy and snowy weather, rain and snow are easily accumulated on the surface of the rearview mirror, resulting in blurred vision, affecting the driver's observation of the traffic conditions behind, thereby increasing driving safety hazards.
