[0002] Currently, intelligent driving has become a hot development direction in the automotive industry, and emerging intelligent driving technologies are gradually being applied to various automotive products. Among them, advanced intelligent driving requires the addition of high-precision sensing components such as LiDAR to meet hardware configuration requirements. LiDAR combines laser technology and radar technology, calculating spatial distance by emitting laser pulses and measuring the time it takes for them to reflect back. It has high spatial resolution and is suitable for accurate object detection and classification. To meet the wide-angle and long-range sensing and detection requirements of LiDAR, it is usually installed on the roof, mounted on a roof sheet metal bracket, and finally covered with a decorative panel on the outside. This involves many components, the matching between components is difficult, and the installation time is long.

[0003] Therefore, it is necessary to provide an improved lidar mounting structure and vehicle to solve the above problems. Utility Model Content

[0005] This application discloses a lidar mounting structure, including a lidar, a top cover panel, and a front crossbeam. The top cover panel is located above and fixed to the front crossbeam. The lidar is mounted between the top cover panel and the front crossbeam. The lidar includes a main body and a mounting part extending outward from the main body. The mounting part is fixed to the top cover panel.

[0006] Furthermore, the top cover trim panel includes an outer trim panel and an inner trim panel stacked together, and the mounting part and the front crossbeam of the top cover are respectively connected to the inner trim panel.

[0007] Furthermore, the outer panel of the decorative panel is bonded and fixed to the inner panel of the decorative panel.

Detailed Implementation

[0028] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0030] The embodiments of this application will now be described in detail. In this embodiment, the front-to-back direction refers to the length direction of the vehicle body, the left-to-right direction refers to the width direction of the vehicle body, and the up-down direction refers to the height direction of the vehicle body.

[0031] like Figure 1 and Figure 2 As shown, this application provides a lidar mounting structure, including a lidar 10, a top cover panel 20, and a front crossbeam 30. The top cover panel 20 is located above the front crossbeam 30, and the lidar 10 is mounted between the top cover panel 20 and the front crossbeam 30. Both the lidar 10 and the front crossbeam 30 are fixed to the top cover panel 20.

[0032] Please refer to the following at the same time Figure 3 The lidar 10 includes a main body 11, a mounting part 12, and an emitting part 13. The mounting part 12 extends outward from the main body 11 and is used to fix it to the top cover panel 20. The emitting part 13 is disposed on the front side of the main body 11 and is used to emit laser light outward. In this embodiment, the mounting part 12 is a plate-shaped boss located on the side of the main body 11 and approximately parallel to the top cover panel 20. The mounting part 12 is disposed near the top of the main body 11 to facilitate connection with the top cover panel 20.

[0033] Specifically, there are four mounting parts 12, which are respectively located on the rear, left, and right sides of the main body 11 and are symmetrically distributed. Two mounting parts 12 are located on the rear side of the main body 11, and one mounting part 12 is located on each of the left and right sides. By symmetrically arranging the mounting parts 12, the tilting or deformation of the lidar 10 caused by unilateral force can be effectively avoided, thereby improving the fixing stability of the lidar 10 and the top cover panel 20.

[0034] The mounting section 12 and the main body 11 are integrally formed, both being aluminum castings. A cavity is formed within the main body 11 for housing the electronic components of the lidar 10. In some cases, a cover plate 14 can be fixed above the main body 11, with the main body 11 and cover plate 14 jointly enclosing the cavity. This application eliminates the need for additional mounting brackets by providing a mounting section 12 extending outward from the main body 11 and fixed to the top cover panel 20, which helps reduce the number of parts, lowers assembly difficulty, and simplifies the assembly process.

[0035] Please refer to the following at the same time Figure 4 The top cover trim panel 20 includes an outer trim panel 21 and an inner trim panel 22 stacked together. The outer trim panel 21 is located on the side away from the front crossbeam 30 of the top cover, and has a simple and smooth overall appearance, which is used to improve the overall integrity and aesthetics of the lidar mounting structure. The inner trim panel 20 is connected to the mounting part 12 and the front crossbeam 30 of the top cover.

[0036] like Figure 2 and Figure 5 As shown, the outer trim panel 21 and the inner trim panel 22 are bonded and fixed together. Several trim panel positioning posts 211 are provided on the side of the outer trim panel 21 near the inner trim panel 22, and several trim panel positioning holes 221 are provided on the inner trim panel 22. The trim panel positioning posts 211 pass through the trim panel positioning holes 221 to fix the relative position of the outer trim panel 21 and the inner trim panel 22, facilitating the assembly of the top cover trim panel 20. In this embodiment, both the outer trim panel 21 and the inner trim panel 22 are made of plastic, which helps to reduce weight and achieve a lightweight design of the overall structure.

[0037] A protruding mounting base 222 is provided on the side of the inner panel 22 near the lidar 10. The number of mounting bases 222 is the same as that of the mounting parts 12, and their positions correspond. The mounting base 222 is hollow inside to further reduce the weight of the top cover panel 20. The bottom of the mounting base 222 fits against the mounting part 12 and is fixed to the mounting part 12 by a first fastener 41. Specifically, the first fastener 41 is a bolt. Both the bottom of the mounting base 222 and the mounting part 12 have through holes. The first fastener 41 passes through the through hole of the mounting part 12 and the through hole at the bottom of the mounting base 222 from bottom to top, thereby fixing the inner panel 22 to the lidar 10.

[0038] Please refer to the following at the same time Figure 6 and Figure 7 The inner panel 22 of the decorative panel is provided with several crossbeam mounting parts 223, crossbeam positioning posts 224 and buckles 225. The front crossbeam 30 of the top cover is provided with several connecting holes 31. Through the cooperation between the crossbeam mounting parts 223, crossbeam positioning posts 224, buckles 225 and connecting holes 31, the positioning and connection between the top cover decorative panel 20 and the front crossbeam 30 of the top cover are realized.

[0039] The crossbeam mounting part 223 is connected to the connecting hole 31 via a second fastener 42. The second fastener 42 is a combination of bolts and nuts. In some cases, such as Figure 8 As shown, due to the gap between the inner trim panel 22 and the front crossbeam 30 of the top cover in some areas, the crossbeam mounting part 223 is a boss to facilitate its fit with the front crossbeam 30 of the top cover. The height of the boss can be flexibly adjusted according to the distance between the inner trim panel 22 and the front crossbeam 30 of the top cover. The crossbeam mounting part 223 is hollow, with a mounting groove 2231 on its side and a mounting hole 2232 on its bottom. The bolt enters the cavity inside the crossbeam mounting part 223 from the mounting groove 2231 on the side and passes through the mounting hole 2232 and the connecting hole 31 in sequence. The bottom of the crossbeam mounting part 223 is provided with a limiting structure that cooperates with the bolt to ensure that the bolt will not rotate after installation. The nut is located on the side of the front crossbeam 30 of the top cover away from the top cover trim panel 20 and cooperates with the bolt to fix the inner trim panel 22 to the front crossbeam 30 of the top cover.

[0040] In some cases, the crossbeam mounting part 223 is an opening directly set on the inner panel 22 of the trim panel. Bolts pass through the openings on the crossbeam mounting part 223 and the connecting holes 31 on the front crossbeam 30 of the top cover in sequence from top to bottom, thereby fixing the inner panel 22 of the trim panel to the front crossbeam 30 of the top cover.

[0041] The crossbeam positioning post 224 and the clip 225 are respectively assembled into the connecting hole 31, eliminating the need for complex installation steps, which helps to improve assembly speed and simplify the assembly process. The crossbeam positioning post 224 extends into the connecting hole 31 to fix the relative position of the inner trim panel 22 and the front crossbeam 30 of the top cover. The clip 225 engages with the connecting hole 31, further improving the connection stability between the inner trim panel 22 and the front crossbeam 30 of the top cover.

[0042] The quantity and arrangement of the crossbeam mounting parts 223, crossbeam positioning posts 224, buckles 225, connecting holes 31, and second fixing members 42 can be flexibly set according to actual needs. In this embodiment, there are 8 crossbeam mounting parts 223 and second fixing members 42, 3 crossbeam positioning posts 224, 4 buckles 225, and 15 connecting holes 31. The 8 second fixing members 42 are 421, 422, 423, 424, 425, 426, 427, and 428, the 3 crossbeam positioning posts 224 are 2241, 2242, and 2243, and the 4 buckles 225 are 2251, 2252, 2253, and 2254, distributed on the front crossbeam 30 of the top cover as follows. Figure 7 As shown.

[0043] Several crossbeam mounting parts 223, crossbeam positioning posts 224, and clips 225 are distributed on the left and right sides of the lidar 10. The crossbeam mounting parts 223 and clips 225 are symmetrically arranged. The crossbeam mounting parts 223, crossbeam positioning posts 224, and clips 225 are arranged along the left-right direction, ensuring that the connection points between the inner panel 22 and the front crossbeam 30 of the top cover are evenly stressed in the left-right direction, avoiding stress concentration on one side and enhancing the stability and reliability of the lidar mounting structure.

[0044] During vehicle assembly, the lidar 10 is first installed on the roof trim panel 20. Then, the fixed lidar 10 and roof trim panel 20 are assembled onto the roof. The lidar 10 is installed by fixing the inner panel 22 to the front crossbeam 30 of the roof. The assembly process of this lidar mounting structure eliminates the need to transport multiple components to the roof for mainline installation in stages. Instead, the lidar 10 and roof trim panel 20 are pre-assembled offline, reducing man-hours and improving installation efficiency.

[0045] Meanwhile, the lidar 10 and the front crossbeam 30 of the top cover share the top cover trim panel 20 as a cover, eliminating the need for an additional lidar cover plate, reducing the number of parts, simplifying the matching between parts, and further improving production efficiency. The lidar 10 is connected inside the top cover trim panel 20, and there is no seam between it and the outermost trim panel 21, thus reducing the risk of water leakage at the seam.

[0046] like Figure 2 As shown, the lidar 10 and the front crossbeam 30 of the top cover have a gap in the height direction, and the gap distance is not less than 5mm. On the one hand, this can reduce the heat conduction between the lidar 10 and the front crossbeam 30 of the top cover, thereby reducing the possibility of the lidar 10 shutting down due to excessively high ambient temperature during continuous operation. On the other hand, it can prevent water from contacting the lidar 10 as much as possible when there is water seepage or water accumulation above the front crossbeam 30 of the top cover, thus reducing the impact on the lidar 10.

[0047] Furthermore, such as Figure 4 As shown, the lidar mounting structure of this application also includes sound-absorbing cotton 50 and a sealing strip 60, both located between the top cover trim panel 20 and the front crossbeam 30. The sound-absorbing cotton 50 is sheet-like and fits snugly against the top cover trim panel 20, filling the gap between the top cover trim panel 20 and the front crossbeam 30, thus providing sound insulation and noise reduction. The sealing strip 60 is fixed to the top cover trim panel 20 and surrounds its contour, achieving a seal between the top cover trim panel 20 and the front crossbeam 30.

[0048] Both the sound-absorbing cotton 50 and the sealing strip 60 are bonded or welded to the inner panel 22 of the decorative panel. In this embodiment, there are two pieces of sound-absorbing cotton 50, which are located on the left and right sides of the lidar 10, respectively. The sealing strip 60 has several notches 61 to facilitate the drainage of water accumulated in the space between the top cover decorative panel 20 and the front crossbeam 30 of the top cover.

[0049] This application also provides a vehicle including a windshield 70, a panoramic glass 80, and a lidar mounting structure as described above.

[0050] like Figure 1 and Figure 2 As shown, the front and rear sides of the lidar mounting structure are connected to the windshield 70 and the skylight 80, respectively. A windshield strip 71 is provided at the top of the windshield 70, which abuts against the top cover panel 20 to achieve a seal between the windshield 70 and the lidar mounting structure. A skylight strip 81 is provided at the front of the skylight 80, which abuts against the top cover panel 20 to achieve a seal between the skylight 80 and the lidar mounting structure.

[0051] The lidar mounting structure and vehicle of this application simplify the assembly process and save installation time by fixing the lidar 10 to the roof trim panel 20, and further fixing the roof trim panel 20 with the lidar 10 to the front crossbeam 30 of the roof. At the same time, fixing the mounting part 12 of the lidar 10 directly to the roof trim panel 20 eliminates the need for additional mounting brackets, which helps to reduce the number of parts, reduce assembly difficulty, and improve production efficiency.

[0052] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
