The rearview camera 4 is fixed in the shell 1, the shell 1 plays a better protective role on the periphery of the rearview camera 4, and damage and pollution of the rearview camera are greatly reduced. Under normal conditions, the baffle plate 2 completely covers the front opening 10 of the shell, namely, the inside of the shell is closed, and external rainwater, dust and foreign matters cannot influence the rearview camera 4. When the rearview camera 4 is used for shooting an area behind an automobile, the driving mechanism 3 drives the baffle plate 2 to move upwards, so that the rearview camera 4 shoots the area behind the automobile without shielding, the cleaning brush is synchronously driven to clean the lens of the rearview camera 4 once in the ascending opening process of the baffle plate 2, after the rearview camera 4 shoots, the driving mechanism 3 drives the baffle plate 2 to move downwards, the baffle plate 2 synchronously drives the cleaning brush to clean the lens of the rearview camera 4 for another time in the descending closing process, the back of the baffle plate 2 moves kinetic energy and the back space of the baffle plate, and the two cleaning combinations form a reciprocating automatic cleaning mode, so that the cleaning effect of multiple angles on the rearview camera 4 can be better achieved, dirt such as dust, rainwater, soil and the like attached to or accumulated on the lens can be better cleaned, cleaning blind areas are reduced, the driving safety is ensured, and the problem that the rearview camera 4 is required to be cleaned and maintained manually at regular intervals is solved.

Compared with the prior art, the protective cleaning mechanism of the automobile rearview camera provided by the utility model has the advantages that the cleaning brush is arranged on the back surface of the baffle plate 2, so that the baffle plate 2 can drive the cleaning brush to automatically and reciprocally clean the lens of the automobile rearview camera 4, the pollutants accumulated on the lens can be effectively removed, the mirror surface of the lens is kept clean continuously, the imaging is ensured to be clear, and the driving safety is ensured.

In this embodiment, as shown in fig. 3, the cleaning brush includes a square-shaped first brush head 61 and first bristles 62 provided on the first brush head 61, and the first brush head 61 is laterally fixed to the back surface of the baffle 2. In the closed state of the shutter 2, the height of the first brush head 61 should be lower than the height of the lens of the rearview camera 4, so as to ensure that the first brush hair 62 on the first brush head 61 can approach the lens of the rearview camera 4 and clean the lens when the shutter 2 is moved upwards and opened.

In another embodiment, as shown in fig. 4, the cleaning brush comprises a disc-shaped second brush head 71 and second bristles 72 arranged on the second brush head 71, a cleaning motor 73 is arranged on the back surface of the baffle 2, and an output shaft of the cleaning motor 73 is in driving connection with the center of the second brush head 71. In the closed state of the baffle 2, a part of the second bristles 72 of the second brush head 71 face the lens of the rearview camera 4, the cleaning motor 73 drives the second brush head 71 and the second bristles 72 to rotate, so that the lens of the rearview camera 4 is cleaned more carefully, the cleaning effect is further improved, and it can be understood that under the non-rotating state of the second bristles 72, part of the second bristles 72 still can sweep the lens of the rearview camera 4 under the driving of the baffle 2.
