For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or communication with each other; it may be a direct connection, or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0044] In the related art, lidars are usually installed on the mounting brackets on the outer panel of the vehicle engine compartment beam, and the position of the lidar relative to the vehicle fender is adjusted by adjusting the position of the mounting bracket. However, it is difficult to control the position of the lidar through the mounting bracket, and the accuracy is poor, resulting in easy out-of-tolerance of the gap between the lidar and the fender, which affects the calibration of the detection angle of the lidar.

[0045] In view of this, the present application provides a lidar assembly installation structure and a vehicle. The lidar assembly installation structure includes a vehicle body, a first mounting bracket, a second mounting bracket, a third mounting bracket, and a lidar assembly. The first mounting bracket is used to mount a fender. The lidar assembly includes a first mounting portion, a second mounting portion, and a third mounting portion. The first mounting portion is in positioning cooperation with the first mounting bracket. The second mounting portion is connected to the second mounting bracket through a first adjusting nut, and the clearance between the lidar assembly and the fender in the height direction of the vehicle body is adjusted through the first adjusting nut. The third mounting portion is connected to the third mounting bracket through a second adjusting nut, and the clearance between the lidar assembly and the fender in the front-rear direction of the vehicle body is adjusted through the second adjusting nut. In this way, the position of the lidar assembly relative to the fender can be adjusted conveniently and precisely, and the clearance surface difference between the lidar assembly and the fender can be reduced.

[0046] The following will describe the present application in detail with reference to the accompanying drawings and specific embodiments.

[0047] See Figures 1 to 10 , the present application provides a lidar assembly installation structure for a vehicle. Among them, the lidar assembly installation structure may include a vehicle body 100, a first mounting bracket 200, a second mounting bracket 400, a third mounting bracket 500, and a lidar assembly 600.

[0048] Specifically, the first mounting brackets 200 are arranged on both sides of the front part of the vehicle body 100 in the width direction. The first mounting brackets 200 are used to mount the fenders 300 and also provide a front reference point for the positioning of the lidar assembly 600.

[0049] Further, the second mounting bracket 400 may be arranged on the vehicle body 100 and is located behind the first mounting bracket 200 in the front-rear direction of the vehicle body 100. Among them, the front-rear direction of the vehicle body 100 is Figure 1 the X-axis direction shown. The third mounting bracket 500 may be arranged on the vehicle body 100 and is located behind the second mounting bracket 400 and has a height lower than that of the second mounting bracket 400.

[0050] Furthermore, the lidar assembly 600 includes a first mounting portion 610, a second mounting portion 620, and a third mounting portion 630. The first mounting portion 610 is in positioning cooperation with the first mounting bracket 200. The second mounting portion 620 is connected to the second mounting bracket 400 through a first adjusting nut 700. The third mounting portion 630 is connected to the third mounting bracket 500 through a second adjusting nut 800. The first adjusting nut 700 is configured to adjust the clearance between the lidar assembly 600 and the fender 300 in the height direction of the vehicle body 100. Among them, the height direction of the vehicle body 100 is Figure 1The Z-axis direction shown. The second adjusting nut 800 is configured to adjust the gap between the lidar assembly 600 and the fender 300 in the front-rear direction.

[0051] It should be noted that, in order to stabilize the installation of the lidar assembly 600 and meet the height adjustment requirements of the lidar assembly 600, the second mounting bracket 400 is provided on the vehicle body 100 and is located at the rear side of the first mounting bracket 200 along the front-rear direction of the vehicle body. In this way, the lidar assembly 600 can maintain an appropriate gap with the fender 300 in the vertical direction. Then, the gap between the lidar assembly 600 and the fender 300 in the vertical direction (i.e., the height direction) is adjusted by the first adjusting nut 700 connected to the second mounting bracket 400. Thus, by rotating the first adjusting nut 700, the staff can finely adjust the height gap between the lidar assembly 600 and the fender 300, thereby ensuring the appearance and function of the lidar assembly 600.

[0052] In order to further improve the flexibility and adaptability of the installation of the lidar assembly 600, the third mounting bracket 500 is provided on the vehicle body 100, is located at the rear side of the second mounting bracket 400, and has a height lower than that of the second mounting bracket 400. In this way, the adjustment of the lidar assembly 600 in the front-rear direction can be realized. The second adjusting nut 800 connected to the third mounting bracket 500 is used to adjust the gap between the lidar assembly 600 and the fender 300 in the front-rear direction. By adjusting the second adjusting nut 800, the staff can accurately control the gap between the lidar assembly 600 and the fender 300 in the front-rear direction to further absorb the gap surface difference between the lidar assembly 600 and the fender 300.

[0053] Thus, through the positioning cooperation between the first mounting portion 610 and the first mounting bracket 200, the position of the lidar assembly 600 relative to the vehicle body 100 can be initially positioned, reducing the adjustment man-hours. Then, by adjusting the first adjusting nut 700, the height gap between the lidar assembly 600 and the fender 300 is accurately adjusted, and by adjusting the second adjusting nut 800, the gap between the lidar assembly 600 and the fender 300 in the front-rear direction is accurately adjusted. Through the combined use of the first adjusting nut 700 and the second adjusting nut 800, the position of the lidar assembly 600 relative to the fender 300 can be conveniently and accurately adjusted, reducing the gap surface difference between the lidar assembly 600 and the fender 300.

[0054] In addition, when there are problems with the function and calibration of the lidar assembly 600 offline and the position of the lidar assembly 600 needs to be adjusted, it can be quickly adjusted through the first adjusting nut 700 and the second adjusting nut 800 for repair and verification. There is no need to disassemble the surrounding parts, improving the production and repair efficiency and saving time cost and labor cost.

[0055] See Figure 2 、 Figure 3 and Figure 6 In the embodiment of the present application, the first mounting portion 610 and the first mounting bracket 200 are positioned and mated through the first self-aligning bolt 900.

[0056] Specifically, a third mounting hole 210 is provided on the first mounting bracket 200, and a third mounting mating hole 611 is provided on the first mounting portion 610 to match the third mounting hole 210. During installation, the first self-aligning bolt 900 sequentially passes through the third mounting mating hole 611 and the third mounting hole 210 to connect the first mounting portion 610 and the first mounting bracket 200, realizing the pre-positioning of the lidar assembly 600.

[0057] As the first self-aligning bolt 900 is gradually tightened, the head of the first self-aligning bolt 900 interacts with the third mounting mating hole 611 and the third mounting hole 210, generating slight rotation and displacement, enabling the lidar assembly 600 to automatically align with the first mounting bracket 200. Thus, the installation process is simplified and the installation efficiency is improved.

[0058] In addition, the locking force of the first self-aligning bolt 900 also ensures the firm connection between the lidar assembly 600 and the first mounting bracket 200, effectively preventing the lidar assembly 600 from shifting or loosening, and ensuring the stability and reliability of the lidar assembly 600 during operation.

[0059] See Figure 3 In the embodiment of the present application, the first mounting portion 610 is located on the front side and upper part of the lidar assembly 600.

[0060] Thus, during installation, the first mounting portion 610 and the first mounting bracket 200 are firmly connected through the first self-aligning bolt 900 to determine the position of the upper front corner of the lidar assembly 600, providing a connection basis for the subsequent connection between the second mounting portion 620 and the second mounting bracket 400, and the connection between the third mounting portion 630 and the third mounting bracket 500, which helps to improve the installation efficiency.

[0061] See Figure 2 、 Figure 4 and Figure 9, in the embodiment of the present application, the second mounting bracket 400 has a first mounting hole 410, and the second mounting portion 620 is provided with a first mounting mating hole 621. Both the first mounting hole 410 and the first mounting mating hole 621 are open along the height direction. The first adjusting nut 700 may include a first fastening nut 710 and a first fastening bolt 720. Among them, the first fastening nut 710 includes a first fixing portion 711 and a first movable portion 712. The first fixing portion 711 is fixedly arranged on the second mounting bracket 400. The first fixing portion 711 defines a first movable cavity 7111. The first movable portion 712 is movably arranged in the first movable cavity 7111 along the opening direction of the first mounting hole 410. The first movable portion 712 defines a first threaded hole 7121 opposite to the first mounting hole 410. The first fastening bolt 720 sequentially passes through the first mounting mating hole 621, the first threaded hole 7121, and the first mounting hole 410 to connect the second mounting portion 620 with the second mounting bracket 400.

[0062] Specifically, the second mounting bracket 400 is provided with a first mounting hole 410 along the height direction, where the height direction is Figure 9 the Z-axis direction shown in. In this way, it is convenient for the alignment operation during the installation process and reserves space for the subsequent adjustment function. In addition, the first mounting mating hole 621 provided on the second mounting portion 620 is opened along the height direction, ensuring the precise docking of the first mounting mating hole 621 and the first mounting hole 410.

[0063] It should be noted that when the first mounting mating hole 621 is opened, the radius of the first mounting mating hole 621 can be slightly larger than the radius of the first fastening bolt 720 (for example, the radius of the first mounting mating hole 621 can be set to be 2 mm larger than the radius of the first fastening bolt 720). In this way, the first mounting mating hole 621 provides an adjustment amount for the first fastening bolt 720 along the width direction of the vehicle body 100 (that is, Figure 1 the Y-axis direction shown in) and along the front-rear direction of the vehicle body 100 (that is, Figure 1 the X-axis direction shown in) to improve the adaptability of the lidar assembly 600.

[0064] To further improve the flexibility and stability of the connection between the second installation part 620 and the second installation bracket 400, the first fastening nut 710 includes a first fixing part 711 and a first movable part 712 located inside the first fixing part 711. The first fixing part 711 is firmly fixed on the second installation bracket 400, and a first movable cavity 7111 is formed inside it, providing a space for the first movable part 712 to move flexibly. In this way, the first movable part 712 can slide along the opening direction of the first installation hole 410, so as to realize fine adjustment of the second installation part 620 in the height direction of the vehicle body 100 during the actual installation process, and reduce the clearance surface difference between the lidar assembly 600 and the fender 300.

[0065] A first threaded hole 7121 defined inside the first movable part 712 maintains a relative position with the first installation hole 410. When the fine adjustment of the second installation part 620 in the height direction of the vehicle body 100 is completed, the first fastening bolt 720 is sequentially passed through the first installation mating hole 621 of the second installation part 620, the first threaded hole 7121 of the first movable part 712, and the first installation hole 410 to firmly connect the second installation part 620 and the second installation bracket 400.

[0066] In the embodiment of the present application, the stroke range of the first movable part 712 in the first movable cavity 7111 is 1.5 mm - 3 mm.

[0067] It should be noted that by moving the first movable part 712 in the first movable cavity 7111, the clearance between the lidar assembly 600 and the fender 300 can be adjusted. Specifically, by adjusting the first movable part 712 within the range of 1.5 mm - 3 mm, the lidar assembly 600 can be adjusted to a proper position to ensure the appearance and function of the lidar assembly 600.

[0068] See Figure 9 , in the embodiment of the present application, a first locking hole 420 is provided at a position on the second installation bracket 400 around the first installation hole 410. The first fixing part 711 is provided with a first locking leg 7112. The first locking leg 7112 passes through the first locking hole 420 and is in locking engagement with the second installation bracket 400.

[0069] It can be understood that the first locking hole 420 is provided around the first installation hole 410 to enhance the connection stability between the second installation bracket 400 and the second installation part 620.

[0070] Specifically, the first fixing part 711, as a component connecting the second mounting part 620 and the second mounting bracket 400, is provided with a first locking leg 7112 thereon. When the first fixing part 711 is aligned and pushed towards the second mounting bracket 400, the first locking leg 7112 will smoothly penetrate into the first locking hole 420 to form a tight mechanical lock. The process of the snap-fit cooperation between the first locking leg 7112 and the first locking hole 420 is easy to operate and ensures the firmness of the connection. The interaction between the first locking leg 7112 and the first locking hole 420 effectively prevents the connection from loosening or falling off due to vibration or external force, thus ensuring the connection stability between the second mounting bracket 400 and the second mounting part 620.

[0071] See Figure 9 , in the embodiment of the present application, the first movable part 712 is in threaded cooperation with the first fixing part 711 so that the first movable part 712 can move along the opening direction of the first mounting hole 410.

[0072] Among them, the threaded cooperation has the advantages of compact structure, reliable connection, convenient adjustment, etc. Specifically, the inner wall of the first fixing part 711 can be provided with internal threads, and the outer wall of the first movable part 712 is correspondingly provided with external threads matching the internal threads. When the first fixing part 711 and the first movable part 712 are screwed together, a stable and adjustable connection structure is formed.

[0073] With such a setting, by rotating the first movable part 712, the first movable part 712 can be accurately moved along the opening direction of the first mounting hole 410, so as to realize the fine adjustment of the second mounting part 620 in the height direction of the vehicle body 100 to reduce the clearance surface difference between the lidar assembly 600 and the fender 300.

[0074] In addition, the threaded cooperation also has a certain self-locking property, making the connection structure able to maintain a relatively stable state. It ensures that the first movable part 712 can be firmly fixed in the current position after moving to the appropriate position and is not prone to loosening or offset.

[0075] See Figure 4 and Figure 8, in the embodiment of the present application, the third mounting bracket 500 has a second mounting hole 510, and the third mounting portion 630 is provided with a second mounting mating hole 631. Both the second mounting hole 510 and the second mounting mating hole 631 are open in the front-rear direction. The second adjusting nut 800 includes a second fastening nut 810 and a second fastening bolt 820. Among them, the second fastening nut 810 may include a second fixing portion 811 and a second movable portion 812. The second fixing portion 811 is fixedly arranged on the third mounting portion 630. The second fixing portion 811 defines a second movable cavity 8111. The second movable portion 812 is movably arranged in the second movable cavity 8111 along the opening direction of the second mounting mating hole 631. The second movable portion 812 defines a second threaded hole 8121 opposite to the second mounting mating hole 631. The second fastening bolt 820 sequentially passes through the second mounting hole 510, the second threaded hole 8121 and the second mounting mating hole 631 to connect the third mounting portion 630 with the third mounting bracket 500.

[0076] It can be understood that the second mounting hole 510 is opened in the third mounting bracket 500 in the front-rear direction, where the front-rear direction is Figure 7 the X-axis direction in []. In addition, the second mounting mating hole 631 provided on the third mounting portion 630 is opened in the front-rear direction, ensuring the precise docking of the second mounting mating hole 631 with the second mounting hole 510.

[0077] When opening the second mounting hole 510, the radius of the second mounting hole 510 can be slightly larger than the radius of the second fastening bolt 820 (for example, the radius of the second mounting hole 510 can be set to be 2 mm larger than the radius of the second fastening bolt 820). In this way, the second mounting hole 510 provides an adjustment amount for the second fastening bolt 820 in the width direction of the vehicle body 100 (that is, Figure 1 the Y-axis direction shown in []) and in the height direction of the vehicle body 100 (that is, Figure 1 the Z-axis direction shown in []), so as to improve the adaptability of the lidar assembly 600.

[0078] Furthermore, the second fastening nut 810 includes a second fixing portion 811 and a second movable portion 812. The second fixing portion 811 is firmly fixed on the third mounting portion 630. The inside of the second fixing portion 811 has a second movable cavity 8111, providing a flexible moving space for the second movable portion 812. In this way, the second movable portion 812 can slide along the opening direction of the second mounting hole 510, so as to realize the fine adjustment of the third mounting portion 630 in the front-rear direction of the vehicle body 100 during the actual installation process, and reduce the gap surface difference between the lidar assembly 600 and the fender 300.

[0079] Among them, a second threaded hole 8121 is provided inside the second movable part 812, maintaining a relative position with the second installation mating hole 631. When fine-tuning the third installation part 630 in the front-rear direction of the vehicle body 100 is completed, the second fastening bolt 820 is sequentially passed through the second installation hole 510, the second threaded hole 8121, and the second installation mating hole 631 to firmly connect the third installation part 630 and the third installation bracket 500.

[0080] In addition, in order to achieve a firm connection between the second fixing part 811 and the third installation part 630, a second locking hole 632 may be provided at a position on the third installation part 630 around the second installation mating hole 631, and the second fixing part 811 is provided with a second locking leg 8112. When the second locking leg 8112 is aligned with and pushed towards the third installation part 630, the second locking leg 8112 will penetrate into the second locking hole 632 to firmly connect with the third installation part 630.

[0081] Furthermore, the second movable part 812 and the second fixing part 811 can be in threaded cooperation. Specifically, an internal thread can be provided on the inner wall of the second fixing part 811, and an external thread matching the internal thread can be provided on the outer wall of the second movable part 812. In this way, when the second movable part 812 and the second fixing part 811 are screwed together, a firm and adjustable connection structure is formed. By rotating the second movable part 812, fine-tuning of the third installation part 630 in the front-rear direction of the vehicle body 100 can be achieved to reduce the clearance surface difference between the lidar assembly 600 and the fender 300.

[0082] See Figure 2 , in the embodiment of the present application, multiple third installation brackets 500 are arranged at intervals in the height direction, and the third installation part 630 corresponds to the third installation brackets 500.

[0083] With such a setting, the connection stability and reliability between the third installation part 630 and the third installation brackets 500 are enhanced. Specifically, the distribution of the multiple third installation brackets 500 in the height direction provides multi-point support for the third installation part 630, effectively dispersing the load and ensuring the connection stability between the third installation part 630 and the third installation brackets 500.

[0084] In addition, the installation flexibility and adaptability are improved. Since the third installation brackets 500 can be adjusted in position in the front-rear direction, the position of the third installation part 630 in the front-rear direction can be precisely adjusted according to actual installation requirements to reduce the clearance surface difference between the lidar assembly 600 and the fender 300.

[0085] It can be understood that the number of the third installation brackets 500 can be set to two, or more than two, and the present embodiment does not limit this here.

[0086] Based on the above embodiments, an embodiment of the present application further provides a vehicle, including the lidar assembly mounting structure provided in any of the above embodiments.

[0087] Among them, the lidar assembly mounting structure has been described in detail in the above embodiments and will not be elaborated here.

[0088] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
