[0002] For the current automobile industry, especially new energy vehicle companies, intelligent assisted driving function has become one of the standard features, and laser radar is one of the necessary hardware configurations to realize high-level intelligent assisted driving function. In the fusion perception solution, laser radar is a key component; the existing patent (Announcement No.: CN 220349622 U) proposes a laser radar decorative panel structure assembly and an automobile body covering component. The laser radar decorative panel structure assembly includes a body, foam and a first sealing member. The body is equipped with a laser radar and is used to abut against the roof sheet metal; the foam is fixed on the side surface of the body facing the laser radar, and surrounds the body for a week, so that the body can be sealed against the roof sheet metal through the foam; in this way, the foam seal can prevent most of the rain from entering the laser radar area, but the exterior panel product is easy to deform and warp at high temperature, increasing the gap between the laser radar interior panel and the top of the car body, and losing a certain degree of sealing; under high-pressure water impact, the current sealing foam sealing effect is not strong enough to play a sealing effect, and the water flow is easy to penetrate into the radar area, causing short circuit and other problems, so the above device structure needs to be improved. Summary of the invention
