Description

Technical Field

[0001] The utility model relates to the technical field of exterior rearview mirrors, in particular to a split foldable electronic exterior rearview mirror base. Background Art

[0002] As the degree of automobile electronics continues to deepen, physical operation and mechanical structure have become the mainstream. Traditional optical rearview mirrors have certain limitations in use. Due to the fixed field of view of traditional exterior rearview mirrors, the clarity is poor at night or in dim environments. In bad weather, especially rainy or snowy days, the side windows covered by rain and snow need to be observed, which will interfere with the line of sight. The side windows and exterior rearview mirrors are prone to fogging in winter, affecting the line of sight. In order to resolve these problems and improve driving safety in recent years, electronic exterior rearview mirrors have become the focus. Electronic exterior rearview mirrors (CMS) use a combination of cameras and monitors to replace traditional optical exterior rearview mirrors. The display mode is that the external camera collects images and displays them on the display screen in the cockpit after processing.

[0003] The existing rearview mirror base is an integral structure made of pure plastic material, without a split base and base bracket. In order to meet the strength requirements, only PA66+GF material can be used. The strength and anti-aging performance of this material are not as good as metal, and the material selection is limited.
