Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior decoration parts, in particular to a compact laser radar assembly structure. Background Art

[0002] With the widespread adoption of smart cars, internet-connected cars, and autonomous vehicles, vehicles are increasingly equipped with LiDAR (LiDAR) sensors to sense the environment, locate internal and external maps, and monitor road conditions to collect signals for driving control. Due to the operating characteristics of LiDAR, it needs to be installed on the front of the vehicle roof, with wiring harnesses connecting it to the electrical module.

[0003] Currently, LiDAR is pre-assembled on a radar trim panel, which is then sub-assembled onto the vehicle body. The addition of the LiDAR creates a protrusion on the vehicle's exterior, increasing air resistance. In addition to housing and supporting the LiDAR, the LiDAR trim panel must also be the same length as the roof on both sides and match the exterior to the vehicle's exterior, ensuring a flawless overall appearance. This also requires significant effort to adjust and align the panel with the vehicle's exterior.

[0004] LiDAR is heavy and generates heat during operation, which accumulates inside the decorative panel. This heat expands and contracts due to the external temperature. Consequently, the panel may exhibit partial shape abnormalities during operation. The larger the decorative panel, the greater the absolute deformation.

[0005] On this basis, it is urgent to develop a compact lidar assembly structure. Utility Model Content
