Description

Technical Field

[0001] The utility model relates to the field of components related to a roof laser radar installation structure, and specifically relates to a decorative cover for installing a laser radar on the top of a vehicle. Background Art

[0002] Vehicle-mounted LiDAR, also known as a vehicle-mounted 3D laser scanner, is a mobile 3D laser scanning system. The 3D laser scanner uses the characteristics of laser propagation speed and good linearity to emit laser light and receive the returned information to describe the surface morphology of the measured physical object. In its original application, vehicle-mounted LiDAR was mainly used in urban modeling. With the rapid development of new energy vehicles in recent years, more and more new energy vehicles have begun to be equipped with LiDAR, and the cooperation between vehicle-mounted LiDAR and vehicle-mounted cameras is used to provide real-time feedback on road conditions.

[0003] In the existing new energy vehicle technology, in order for the on-board laser radar to have a better scanning field of view, the laser radar is generally installed on the top or side of the vehicle, which is also a protection measure for the laser radar. If the on-board laser radar is to be installed on the surface of the top of the vehicle, it is necessary to set up a mounting structure on the decorative cover on the top and side of the vehicle to facilitate the installation and protection of the on-board laser radar.

[0004] For example, the Chinese patent with patent number ZL202220615917.2 discloses: "A mounting structure, positioning tooling and automobile for a vehicle-mounted laser radar, comprising a vehicle body floor, a vehicle body outer panel and a laser radar, a decorative cover plate being mounted on the vehicle body outer panel, and a second mounting hole corresponding to the laser radar being opened on the decorative cover plate; the detection end of the laser radar extends into the second mounting hole, and there is a gap between the side wall of the laser radar and the hole wall of the second mounting hole; a first positioning structure is provided on the vehicle body floor, and the laser radar is mounted on the vehicle body floor through the first positioning structure; a second positioning structure is provided on the vehicle body outer panel, and the decorative cover plate is mounted in the first mounting hole through the second positioning structure. The utility model adopts the positioning tooling to install the laser radar, and the positioning and fastening of the laser radar are carried out on two structural members, which not only solves the problem of installation reliability, but also ensures that the gap between the laser radar and the decorative cover plate is controllable."

[0005] The above patent describes the installation structure of the laser radar on the side of the car. Since the top of the vehicle is subject to greater wind resistance than the side of the vehicle, the stability of the laser radar installation structure will be higher when the laser radar is installed on the top of the vehicle. In order to improve the stability of the existing installation structure on the top of the vehicle on the market, a large number of bolts and clips are considered to strengthen the connection between the laser radar and the decorative cover. This will not only increase the volume of the entire decorative cover, but also increase the weight of the vehicle body. Therefore, there is an urgent need to develop a laser radar installation decorative cover for the top of the vehicle, which can not only ensure the stability of the installation structure, but also will not affect the volume and weight of the vehicle body. Summary of the Invention
