Technical Field

[0001] The utility model relates to the technical field of laser radar, in particular to a protective water retaining structure for automobile laser radar. Background Art

[0002] With the development of science and technology, existing cars are equipped with autonomous driving technology. In the field of autonomous driving, Lidar has become an indispensable technical component due to its high-precision distance measurement and rapid environmental adaptability. With the continuous advancement of autonomous driving technology, vehicles have increasingly higher requirements for their ability to perceive the surrounding environment, which makes the role of Lidar even more important. The greatest advantage of Lidar lies in its precise ranging capability and high resolution. It detects objects by emitting laser pulses and measuring the light reflected back, thereby providing three-dimensional position data, which is crucial for achieving autonomous driving functions above SAE Level L2. In addition, compared with traditional cameras and millimeter-wave radars, Lidar is more adaptable to adverse weather and lighting conditions, providing more reliable environmental perception data for autonomous vehicles.

[0003] Automotive LiDAR systems are typically waterproof, resistant to rain and inclement weather. To mitigate the effects of rain on autonomous driving systems, many LiDAR manufacturers incorporate waterproofing into their designs. However, this lack of waterproofing in LiDAR interfaces can lead to damage and consequent LiDAR failure. Utility Model Content
