Description

Technical fields:

[0001] This utility model belongs to the field of automotive technology, and specifically refers to a car roof decorative panel equipped with lidar and auxiliary lighting components. Background technology:

[0002] With the rapid development of intelligent driving technology, multi-sensor fusion perception has become a core technical path for achieving accurate environmental modeling. LiDAR, with its high-precision 3D point cloud generation capability, is widely deployed at high-mounted locations such as vehicle roofs to obtain unobstructed, wide-area detection fields.

[0003] However, the existing collaborative design of LiDAR and headlight systems still has significant shortcomings: current vehicle headlights are mainly concentrated on both sides of the front of the vehicle, using floodlighting to meet basic driving visibility needs, but the overlap between their illumination range and the LiDAR detection area is limited. Especially in low-light scenarios such as at night or in tunnels, although LiDAR can independently complete ranging and contour recognition, other visual sensors such as vehicle cameras are prone to problems such as increased image noise and difficulty in feature extraction due to insufficient ambient light, resulting in a decrease in the effectiveness of multimodal data fusion and affecting the robustness of system decision-making. Summary of the Invention:

[0004] The purpose of this invention is to provide a car roof trim panel equipped with a lidar and auxiliary lighting components. The auxiliary lighting components are added to both sides of the lidar, so that the lighting direction of the auxiliary lighting components is at the same height and direction as the lidar detection direction. This enhances the ability of other vehicle sensors to capture objects with low reflectivity under low light conditions, and ensures that the detection data of other vehicle sensors and lidar form redundant verification.

[0005] This utility model is implemented as follows:

[0006] A car roof trim panel equipped with a lidar and auxiliary lighting components includes a trim cover plate and a trim base plate that can be spliced ​​vertically. An accommodating chamber with an opening facing forward is formed between the trim cover plate and the trim base plate. A lidar with a detection end corresponding to the opening position is fixed in the accommodating chamber. An auxiliary lighting component is provided on the trim cover plate or trim base plate located on the left and right sides of the lidar detection end. Both the detection end of the lidar and the illumination end of the auxiliary lighting component are facing forward.

[0007] In the aforementioned automotive roof trim panel equipped with a lidar and auxiliary lighting components, a pre-embedded sheet metal is embedded in the trim base plate located directly below the lidar and the two headlights. The trim base plate is formed by secondary injection molding on the pre-embedded sheet metal. The lidar and the two auxiliary lighting components are respectively fixedly connected to the corresponding pre-embedded sheet metal by fasteners.

[0008] In the aforementioned automotive roof trim panel equipped with a lidar and auxiliary lighting components, the auxiliary lighting components include a front trim housing fixed to the trim panel, the front trim housing having a forward-facing lighting mounting slot, and an auxiliary lighting unit being provided in the lighting mounting slot.

[0009] In the aforementioned automotive roof trim panel equipped with a lidar and auxiliary lighting components, the front trim housings of the two auxiliary lighting components form an integrated structure through a middle connecting part. A detection window is provided on the middle connecting part, and a detection cover is fitted on the detection window to allow the detection end of the lidar to detect the outside world.

[0010] In the aforementioned automotive roof trim panel equipped with a lidar and auxiliary lighting components, the front trim housing is connected to the auxiliary lighting unit via a lighting screw. The tail end of the lighting screw passes through the rear end face of the front trim housing from back to front to the lighting mounting slot. The rear end face of the front trim housing is covered by a snap-fit ​​cover that completely covers the head end of the lighting screw.

[0011] In the aforementioned automotive roof trim panel equipped with a lidar and auxiliary lighting components, the upper surface of the trim panel arches upward in the horizontal direction to form a positioning boss, and the lower surface of the front trim housing is provided with a positioning groove for the positioning boss to be inserted.

[0012] In the aforementioned automotive roof trim panel equipped with lidar and auxiliary lighting components, the trim panel and the trim base plate are fixedly connected by adhesive pressing.

[0013] The outstanding advantages of this utility model compared to the prior art are:

[0014] This utility model has a simple structure and reasonable design, and physically integrates the sensing and lighting modules. By adding auxiliary lighting components on both sides of the lidar, the lighting direction of the auxiliary lighting components is kept at the same height and direction as the lidar detection direction.

An accommodating chamber with an opening facing forward is formed between the trim cover plate 1 and the trim base plate 2. A lidar 3, whose detection end corresponds to the opening position, is fixed within the accommodating chamber. Auxiliary lighting components are disposed on the trim cover plate 1 or trim base plate 2 located on the left and right sides of the detection end of the lidar 3, with both the detection end of the lidar 3 and the illumination end of the auxiliary lighting components facing forward. Furthermore, in this embodiment, the auxiliary lighting components are narrow-beam and highly directional lighting units.

[0021] This utility model has a simple structure and reasonable design, and physically integrates the sensing and lighting modules.

That is, it is fixedly connected to the pre-embedded sheet metal 4 after passing through the front decorative housing 5 and the decorative cover plate 1 from top to bottom by fasteners.

[0024] In order to improve the overall structural connection stability between the two auxiliary lighting components and the car roof trim panel, the front trim housings 5 ​​of the two auxiliary lighting components are integrated into a single structure through the intermediate connecting part 7. Correspondingly, in order to avoid interference of the intermediate connecting part 7 with the detection of the lidar 3, a detection window is provided on the intermediate connecting part 7, and a detection cover 8 is installed on the detection window for the detection end of the lidar 3 to detect the outside world.

[0025] Meanwhile, in order to prevent external factors from affecting the connection stability between the auxiliary lighting unit and the front decorative housing 5, the front decorative housing 5 is connected to the auxiliary lighting unit 6 by a lighting screw. The tail end of the lighting screw passes through the rear end face of the front decorative housing 5 from back to front to the lighting assembly slot. The rear end face of the front decorative housing 5 is covered by a snap-fit ​​cover that completely covers the head end of the lighting screw.

[0026] Furthermore, in order to facilitate the assembly of the auxiliary lighting components onto the decorative cover plate 1, the upper end face of the decorative cover plate 1 is arched upward in the horizontal direction to form a positioning boss 10, and the lower end face of the front decorative housing 5 is provided with a positioning groove for the positioning boss 10 to be inserted.
