Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted laser radar, in particular to a cleaning structure for a vehicle-mounted laser radar. Background Art

[0002] The laser radar system is a system that emits laser beams to detect target position, speed and other characteristics. Its working principle is as follows: the laser transmitter emits a laser beam, which is collimated by the reflective optical system and then projected through the filter in front to the scanning area for scanning. When there is an object in the scanning area, the laser beam will be reflected to form an echo beam. After passing through the filter, the echo beam is focused by the receiving optical system and received by the laser receiver, and then the distance is determined based on the time difference between sending and receiving, or based on the phase difference.

[0003] At present, laser radar is used more and more widely as a light detection and ranging device. For example, when it is used in vehicles, it is usually necessary to expose the laser radar to the environment. Dust and other stains in the environment will adhere to the surface of the filter cover of the laser radar. The dust and other stains attached to the surface of the filter cover will interfere with the scanning detection of the laser radar, so that the stains will be mistakenly detected as targets during the detection process, and the distance data will be output, resulting in an inability to obtain accurate measurement results. A cleaning device is required to clean the radar. The patent application with publication number CN216052198U proposed in the prior art releases the airflow restraint by shutting down the micro-blower, and the curved ring disk and the guide rod are pulled back by a tension spring. During this process, the bristles of the inner ring are scraped on the surface of the radar terminal, so as to realize the automatic cleaning process after the surface of the radar terminal is dirty, and the cleaning work is more flexible and convenient. However, when the current cleaning structure uses a spring to pull the bristles up and down to clean the surface impurities of the radar, when the solid impurities appear and adhere to the surface of the radar, it is difficult to handle the solid impurities by cleaning by pulling up and down.

[0004] Therefore, it is necessary to provide a cleaning structure for a vehicle-mounted laser radar to solve the above-mentioned technical problems. Utility Model Content
