Description

Technical Field

[0001] The utility model belongs to the technical field of laser radars, and in particular relates to a high-performance automotive laser radar light-transmitting component. Background Art

[0002] Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of a target. Its working principle is to emit a detection signal (laser beam) to the target, and then compare the received signal reflected from the target (target echo) with the transmitted signal. After appropriate processing, relevant information about the target can be obtained, such as target distance, direction, height, speed, attitude, and even shape parameters, so as to detect, track and identify targets such as aircraft and missiles.

[0003] Authorization publication number "CN220199193U" discloses a vehicle-mounted laser radar installation structure and a vehicle, which relates to the technical field of automobile parts. The vehicle-mounted laser radar installation structure includes a vehicle outer cover shell and a sealing soft rubber structure. The vehicle outer cover shell is provided with a radar installation hole. The sealing soft rubber structure is arranged along the circumference of the radar installation hole. The sealing soft rubber structure is connected to the vehicle outer cover shell on the side away from the center of the radar installation hole. The sealing soft rubber structure extends toward the side of the center of the radar installation hole to form a sealing lip, which is used to abut the laser radar. In the vehicle-mounted laser radar installation structure of the utility model, the sealing soft rubber structure is connected to the vehicle outer cover shell on the side away from the center of the radar installation hole to form a first seal. The sealing soft rubber structure extends toward the side of the center of the radar installation hole to form a sealing lip that abuts the laser radar to form a second seal. The sealing effect is good, which effectively extends the service life of the laser radar.

[0004] The sealing lip formed by the new sealing soft rubber structure extending toward the center side of the radar mounting hole abuts against the laser radar to form a second seal with good sealing effect, which effectively extends the service life of the laser radar. However, the new type of laser radar is fixed during installation and cannot change direction. When the car turns, the direction of the laser radar is the same as the direction of the front of the car. The laser radar cannot change direction to detect the direction of the car's turn in advance, and can only follow the direction of the front of the car for detection in real time, which reduces the detection viewing angle of the car's laser radar.
