Abstract

The invention discloses a protection device (1) for automobile laser radar (2). The protection device (1) comprises a lower connection part (12), an upper top cover, a waterproof and dustproof fabric(13) and a connection device (14), wherein the lower connection part (12) is used for being fixed at the top of the laser radar (2), the upper top cover (11) is connected to the lower connection part(12) in a releasing way, the waterproof and dustproof fabric (13) is accommodated in a cavity formed from the lower connection part (12) and the upper top cover (11), and the connection device (14) isused for connecting the waterproof and dustproof fabric (13) to the lower connection part (12). The protection device (1) can be conveniently fixed at the automobile laser radar (2), the laser radar(2) is prevented from being polluted by rain and dust, and the protection device is simple in structure.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a protection device for laser radars used in automobiles. Background technique [0002] Cars with self-driving or driver-assist features are often equipped with lidar to detect the car's surroundings. The laser transmitter of the lidar emits a laser beam. After the laser beam encounters an object, it is reflected and returns to the laser receiver. The radar module calculates the distance between the laser transmitter and the object according to the time interval between sending and receiving signals, so as to provide the vehicle basis for manipulation. [0003] However, rain or dust may pollute the laser beam emission port of the lidar, which will affect the emission and reception of the laser beam, resulting in inaccurate information obtained by the lidar and affecting driving safety. [0004] For this reason, the prior art has proposed some protection devices for the laser radar of...
