一种支持电动清洗的后摄像头电动结构和后摄像头A rear camera electric structure and rear camera supporting electric cleaning

技术领域technical field

本发明涉及汽车技术领域，更具体地，涉及一种支持电动清洗的后摄像头电动结构和后摄像头。The invention relates to the technical field of automobiles, and more particularly, to an electric structure of a rear camera and a rear camera supporting electric cleaning.

背景技术Background technique

随着汽车在驾驶辅助各项配置的成熟化，现在倒车影像配置基本标配，同时电动后摄像头喷水清洁装置也在逐步市场化。但目前的电动后摄像头喷水清洁装置全为固定喷射角度，且与后摄像头基本齐平，但后摄像头透镜多为凸透镜，导致背对喷嘴方向的的后摄像头透镜无法得到有效清洁。所以电动后摄像头喷水清洁装置的顾客体验较差。With the maturity of various configurations of driving assistance in cars, the configuration of reversing cameras is now basically standard, and the electric rear camera water spray cleaning device is gradually being marketed. However, the current electric rear camera water jet cleaning devices all have a fixed spray angle and are basically flush with the rear camera, but the rear camera lens is mostly a convex lens, so that the rear camera lens facing away from the nozzle cannot be effectively cleaned. Therefore, the customer experience of the electric rear camera water jet cleaning device is poor.
