Further, as shown in fig. 5, a mounting surface having a recess depth gradually increasing toward a rear end along a front end of the front roof rail is formed in the first mounting pocket 300, and the laser radar is disposed on the mounting surface.
It should be noted that, in order to meet the modeling requirements of the vehicle, the front roof rail 3 is usually configured to be an inclined structure with a relatively lower front end and a relatively higher rear end, that is, the surface of the front roof rail 3 for mounting and supporting the roof outer trim 2 is configured to be an inclined surface structure, when the laser radar 1 is mounted on the front roof rail 3, in order to prevent the rear end of the laser radar 1 from being too high, in the present embodiment, a mounting surface with a depth gradually increasing from the front to the concave depth is formed in the first mounting cavity 300, and the laser radar is disposed on the mounting surface, so as to ensure that the laser radar 1 does not excessively protrude out of the front roof rail 3 after being mounted, and further ensure the appearance modeling effect of the vehicle.
Specifically, the mounting surface 301 is recessed with respect to the surface of the front roof rail 3 facing the roof outer 2, and the inclination angle of the mounting surface 301 with respect to the surface of the front roof rail 3 facing the roof outer 2 is 6 ° or more and 10 ° or less, specifically, may be 6 °, 7 °, 8 °, 9 °, 10 °, or the like. By the setting of the inclination angle, it is achieved that the inclination angle of the mounting surface 301 with respect to the horizontal plane is smaller than the inclination angle of the mounting support surface 306 with respect to the horizontal plane, and the mounting surface 301 is still set to be inclined upward gradually from front to rear with respect to the horizontal plane.
Specifically, along the direction of the front end of roof front crossbeam 3 to the rear end, installation face 301 upwards inclines gradually for the horizontal plane and sets up, and the inclination angle more than or equal to 2 and less than or equal to 4 of installation face 301 for the horizontal plane, specifically can be 2 °, 3 °, 4 etc., so as to guarantee under the not too high prerequisite of the rear end of lidar 1, make lidar 1 from preceding backward installation height increase gradually, in order to satisfy vehicle appearance molding's demand to lidar 1's installation angle better, thereby ensure the appearance molding effect of vehicle, and ensure the realization of lidar 1 normal detection function.
