Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0038] Please refer to Figures 1 to 9 The exemplary embodiments of the present application provide a laser radar mounting bracket 100. The laser radar mounting bracket 100 is suitable for being mounted on a vehicle to mount a laser radar 400 on the vehicle. The laser radar 400 is used to detect objects around the vehicle, passable space, etc., and can be calibrated by a sensor, so that the vehicle body knows the position of the obstacle, etc., so that the vehicle driving is more intelligent and the driving safety is improved. The laser radar mounting bracket 100 comprises a bracket 10 and a decorative plate 30.

[0039] Please refer to Figure 1 and Figure 2As shown, the bracket 10 is used to accommodate and fix the lidar 400, so as to facilitate the installation of the lidar 400 through the bracket 10. The lidar 400 and the bracket 10 constitute a lidar assembly 200. The lidar 400 can be detachably fixed on the bracket 10. The detachable connection can be realized by the cooperation of screws and bolts, etc. The lidar 400 can also be integrated with the bracket 10.

[0040] Exemplarily, the bracket 10 includes a mounting plate 101, and the lidar 400 is fixed at four mounting positions of the mounting plate 101, which are arranged in a rectangular shape, so as to stably fix the lidar 400 on the mounting plate 101.

[0041] In some embodiments, the bracket 10 includes a metal material such as aluminum, so as to ensure that the bracket 10 has good supporting strength.

[0042] Please refer to Figures 3 to 9 As shown, the decorative plate 30 includes a receiving cavity 301 for accommodating the lidar 400. The decorative plate 30 not only plays a role in sound insulation and heat insulation. The decorative plate 30 can also play a protective role for the lidar assembly 200, reducing the risk of damage to the lidar 400.

[0043] In some embodiments, please refer to Figure 4 and Figure 5 As shown, the decorative plate 30 also includes an opening 302. The opening 302 penetrates the decorative plate 30 along the first direction X and communicates with the receiving cavity 301, so as to expose the radar mirror 401. In this way, it is convenient for laser to be emitted from the radar mirror 401, and then to scan the environment around the vehicle 600, etc.

[0044] In some embodiments, the radar mirror 401 penetrates the opening 302 and is located outside the receiving cavity 301.

[0045] In some embodiments, the decorative plate 30 can include an organic material such as plastic, so that the decorative plate 30 has the advantages of light weight and easy processing and molding.

[0046] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, the bracket 10 has a first positioning portion 20. The decorative plate 30 has a second positioning portion 21. The second positioning portion 21 is attached to the first positioning portion 20 in the first direction X, so as to realize the positioning of the lidar 400 in the first direction X, and improve the positioning accuracy of the lidar 400 in the first direction X when the lidar 400 is installed on the decorative plate 30 through the bracket 10.

[0047] The radar mirror 401 of the laser radar 400 faces a first direction X. The first direction X can be a front-rear direction of the vehicle 600, and the front-rear direction of the vehicle 600 is respectively provided with a front windshield and a rear windshield of the vehicle 600. It can be understood that the first direction X can also be a left-right direction of the vehicle 600.

[0048] In some embodiments, referring to Figure 1 and Figure 2 , the first positioning part 20 comprises a first positioning surface 201. The first positioning surface 201 faces the first direction X to realize the positioning of the laser radar 400 in the first direction X. When the laser radar 400 is installed on the decorative plate 30 through the support 10, the first positioning surface 201 of the first positioning part 20 is attached to the structure on the decorative plate 30 to realize the positioning in the first direction X, thereby improving the positioning accuracy of the laser radar 400 installed on the decorative plate 30.

[0049] In some embodiments, the first positioning surface 201 comprises a plane to reduce the attachment difficulty of the first positioning surface 201 during positioning. In other embodiments, the first positioning surface 201 can also be a curved surface.

[0050] In some embodiments, the first positioning surface 201 intersects the first direction X, for example, the first positioning surface 201 is perpendicular to the first direction X, but is not limited thereto. The included angle between the first positioning surface 201 and the first direction X can also be an acute angle or an obtuse angle.

[0051] In some embodiments, referring to Figure 1 and Figure 2 , the first positioning part 20 further comprises a first connecting hole 202. In this way, the first positioning part 20 not only plays a positioning role, but also plays a fixed connection role.

[0052] In some embodiments, the first connecting hole 202 penetrates the first positioning part 20 along the first direction X. In this way, the first positioning part 20 can play a fixed connection role in the first direction X, thereby realizing the anti-rotation function of the laser radar 400 in the first direction X.

[0053] In some embodiments, the first positioning surface 201 is arranged around the first connecting hole 202.

[0054] In some embodiments, the first connecting hole 202 can be a threaded hole, but is not limited thereto. A bolt is inserted into the first connecting hole 202 and connected by screwing. In other embodiments, the inner wall of the first connecting hole 202 can be smooth without threads.

[0055] In some embodiments, the area of the first positioning surface 201 is greater than the area of the first connecting hole 202 to increase the attachment area of the first positioning surface 201 in the first direction X.

[0056] In some embodiments, referring to Figure 1 and Figure 2 , two first positioning portions 20 are oppositely arranged in the second direction Y. The second direction Y intersects the first direction X. In this way, the two first positioning portions 20 can define a line, and the line can better achieve the anti-rotation function of the lidar 400 in the first direction X.

[0057] In some embodiments, the mounting direction between the bracket 10 and the lidar 400 can intersect the second direction Y. The second direction Y can be the left-right direction of the vehicle 600, and the left-right direction of the vehicle 600 is respectively provided with a door.

[0058] In some embodiments, referring to Figure 1 and Figure 2 , the first positioning portion 20 can include a first mounting lug, and the two first mounting lugs are located on the opposite sides of the bracket 10 in the second direction Y and are connected to the same end of the bracket 10 in the first direction X. The first mounting lug includes a first positioning surface 201 and is provided with a first connecting hole 202.

[0059] In some embodiments, referring to Figure 1 and Figure 2 , the first positioning portion 20 is connected to the front end of the bracket 10 in the first direction X. The front end of the bracket 10 in the first direction X is adjacent to the radar mirror 401. In this way, the first positioning portion 20 can improve the positioning accuracy of the radar mirror 401 in the first direction X.

[0060] In some embodiments, referring to Figure 5 and Figure 6 , and Figure 8 , the second positioning portion 21 includes a second positioning surface 211. As shown in Figure 8 , the second positioning surface 211 faces the first direction X and is attached to the first positioning surface 201 to achieve the positioning of the lidar 400 and the decorative plate 30 in the first direction X. In this way, the surface attachment between the second positioning surface 211 of the second positioning portion 21 and the first positioning surface 201 of the first positioning portion 20 achieves the positioning of the lidar 400 and the decorative plate 30 in the first direction X.

[0061] In some embodiments, in the case where the first positioning surface 201 includes a plane, the second positioning surface 211 can also include a plane to reduce the difficulty of attaching the first positioning surface 201 and the second positioning surface 211.

[0062] In some embodiments, the area of the second positioning surface 211 can be different from the area of the first positioning surface 201, reducing the difficulty of fitting between the second positioning surface 211 and the first positioning surface 201, and further reducing the difficulty of alignment between the first positioning part 20 and the second positioning part 21. For example, the area of the second positioning surface 211 is greater than the area of the first positioning surface 201.

[0063] In some embodiments, referring to Figure 5 and Figure 6 and Figure 8 As shown, the second positioning part 21 further comprises a second connecting hole 212. The second connecting hole 212 cooperates with the first connecting hole 202 to realize the connection of the second positioning part 21 and the first positioning part 20. In this way, the second positioning part 21 not only plays a positioning role, but also cooperates with the first positioning part 20 to realize the fixed connection when the laser radar assembly 200 is installed on the decorative plate 30.

[0064] In some embodiments, when the first connecting hole 202 penetrates the first positioning part 20 along the first direction X, the second connecting hole 212 penetrates the second positioning part 21 along the first direction X. The second connecting hole 212 cooperates with the first connecting hole 202 to realize the fixed connection in the first direction X when the laser radar assembly 200 is installed on the decorative plate 30, and further realize the anti-rotation function of the laser radar 400 in the first direction X.

[0065] In some embodiments, the second positioning surface 211 is arranged around the second connecting hole 212.

[0066] In some embodiments, the area of the second positioning surface 211 can be greater than the area of the second connecting hole 212.

[0067] In some embodiments, the second connecting hole 212 can be a threaded hole, but is not limited thereto. A bolt is inserted into the second connecting hole 212 and connected by screwing. The inner wall of the second connecting hole 212 can be smooth and without threads.

[0068] When the second positioning surface 211 of the second positioning part 21 is fitted with the first positioning surface 201 of the first positioning part 20, the second connecting hole 212 overlaps the first connecting hole 202 in the first direction X, for example, the two are aligned in the first direction X, so that the fastener such as a bolt passes through the first connecting hole 202 and the second connecting hole 212, and further realizes the fixed connection of the laser radar 400 in the first direction X.

[0069] In some embodiments, the second positioning part 21 can comprise a first snap spring nut, but is not limited thereto. In this way, the second positioning part 21 not only comprises a third positioning surface 231 and a third connecting hole 232, but also can be more easily installed in the accommodation cavity 301.

[0070] In some embodiments, the second positioning part 21 is fixed on the side wall of the accommodating cavity 301. In some embodiments, the decorative plate 30 can include a first mounting plate 303 and a second mounting plate 304 arranged opposite in the third direction Z, and the first snap spring nut is clamped between the first mounting plate 303 and the second mounting plate 304. The first mounting plate 303 and the second mounting plate 304 can be connected to the side wall of the accommodating cavity 301.

[0071] In some embodiments, the second positioning part 21 is adjacent to the opening 302. At least two second positioning parts 21 are respectively located on the opposite sides of the opening 302 in the second direction Y, and the second direction Y intersects the first direction X. In this way, the second positioning part 21 cooperates with the first positioning part 20 to improve the positioning accuracy of the radar mirror 401 adjacent to the opening 302 in the first direction X. Moreover, the at least two second positioning parts 21 and the at least two first positioning parts 20 define a line or a plane, which better realizes the anti-rotation function of the lidar 400 in the first direction X.

[0072] In some embodiments, when the second positioning part 21 includes the first snap spring nut, the first bolt can pass through the first connecting hole 202 and be inserted into the first snap spring nut and connected by screwing with the threads of the first snap spring nut, so as to realize the positioning and mounting of the decorative plate 30 and the lidar assembly 200 in the first direction X.

[0073] In some embodiments, as shown in Figure 1 and Figure 2 , the lidar mounting bracket 100 further includes a third positioning part 22. The third positioning part 22 is connected with the decorative plate 30. The third positioning part 22 is used to realize the positioning of the lidar 400 in the third direction Z. The third direction Z intersects the first direction X. In this way, the third positioning part 22 is used to realize the positioning of the lidar 400 in the third direction Z, which improves the positioning accuracy of the lidar 400 mounted on the decorative plate 30 in the third direction Z.

[0074] In some embodiments, the third direction Z is the mounting direction between the lidar 400 and the bracket 10. For example, the third direction Z can be the up-down direction of the vehicle 600.

[0075] In some embodiments, the third positioning part 22 is arranged apart from the first positioning part 20. In this way, the positioning difficulty of the third positioning part 22 and the first positioning part 20 is reduced.

[0076] In some embodiments, the third positioning part 22 is connected with the lidar 400. In this way, the lidar 400 is better positioned, and the structure of the bracket 10 is simplified. In other embodiments, the third positioning part 22 can also be connected with the bracket 10.

[0077] In some embodiments, at least one of the first positioning portion 20 and the third positioning portion 22 is arranged close to the side of the radar mirror 401 of the lidar 400. In this way, the first positioning portion 20 and the third positioning portion 22 improve the positioning accuracy of the radar mirror 401 of the lidar 400 in the first direction X and the third direction Z, respectively.

[0078] In some embodiments, the third positioning portion 22 is configured as a groove 222 arranged in the second direction Y. The second direction Y intersects the first direction X. In this way, the positioning of the lidar 400 and the decorative plate 30 in the third direction Z is achieved by the groove 222.

[0079] In some embodiments, as shown in Figure 1 and Figure 2 , the third positioning portion 22 includes two clamping portions 221 connected to each other. The two clamping portions 221 are arranged in the third direction Z. The groove 222 is arranged between the two clamping portions 221 and faces away from the bracket 10. In this way, the positioning accuracy of the lidar 400 in the third direction Z is improved by the limiting effect of the groove 222 defined by the two clamping portions 221 in the third direction Z. Moreover, the third positioning portion 22 includes two clamping portions 221 connected to each other, which can also reduce the space occupied and reduce the installation difficulty of the front end of the lidar 400. In addition, the groove 222 faces away from the bracket 10, which facilitates the assembly between the third positioning portion 22 and the decorative plate 30.

[0080] In some embodiments, the groove 222 can be U-shaped, but is not limited thereto.

[0081] In some embodiments, as shown in Figure 1 and Figure 2 , the number of third positioning portions 22 is at least two, and the at least two grooves 222 are arranged opposite to each other in the second direction Y. The second direction Y intersects the first direction X. In this way, the at least two third positioning portions 22 can define a line or a plane, and a line or a plane is used to better achieve the positioning effect of the front end of the lidar 400 in the third direction Z.

[0082] In some embodiments, as shown in Figure 1 and Figure 2 , the bracket 10 further has a fourth positioning portion 23. The fourth positioning portion 23 is connected to the decorative plate 30 and is used to achieve the positioning of the lidar 400 in the third direction Z. In this way, the fourth positioning portion 23 cooperates with the third positioning portion 22 to achieve the positioning of the lidar 400 in the third direction Z.

[0083] In some embodiments, the fourth positioning part 23 and the third positioning part 22 are located on opposite sides of the bracket 10 in the first direction X. The fourth positioning part 23 and the third positioning part 22 can define a plane, achieving large plane positioning in the third direction Z, and better achieving positioning of the laser radar 400 in the third direction Z.

[0084] In some embodiments, the first positioning part 20 is located between the fourth positioning part 23 and the third positioning part 22 in the first direction X, and the third positioning part 22 is adjacent to the radar mirror 401 of the laser radar 400. The third positioning part 22 achieves positioning of the radar mirror 401 in the third direction Z. The fourth positioning part 23 is located at the rear end of the laser radar 400 away from the radar mirror 401, achieving positioning of the rear end of the laser radar 400 in the third direction Z. Moreover, the first positioning part 20 is located between the fourth positioning part 23 and the third positioning part 22, and the distance between the fourth positioning part 23 and the third positioning part 22 is large, increasing the area of the large positioning plane in the Z direction, and better achieving positioning of the laser radar 400 in the Z direction. At the same time, the first positioning part 20 has more space in the first direction X, and can be more flexibly arranged.

[0085] In some embodiments, as shown in Figure 2 , the fourth positioning part 23 includes a third positioning plane 231 facing the third direction Z. In this way, when the laser radar 400 is installed on the decorative plate 30 through the bracket 10, the third positioning plane 231 of the fourth positioning part 23 is surface-fitted with the decorative plate 30 to achieve positioning in the third direction Z, improving the positioning accuracy of the laser radar 400 in the third direction Z when installed on the decorative plate 30.

[0086] In some embodiments, the third positioning plane 231 can include a flat surface to reduce the difficulty of fitting the third positioning plane 231 during positioning. In other embodiments, the third positioning plane 231 can also be a curved surface.

[0087] In some embodiments, as shown in Figure 1 and Figure 2 , the fourth positioning part 23 further includes a third connecting hole 232. The fourth positioning part 23 is connected to the decorative plate 30 through the third connecting hole 232. In this way, the fourth positioning part 23 not only plays a positioning role, but also can play a fixed connection role.

[0088] In some embodiments, the third connecting hole 232 penetrates the fourth positioning part 23 along the third direction Z. In this way, the fourth positioning part 23 can also play a fixed connection role in the third direction Z.

[0089] In some embodiments, the third connecting hole 232 can be a threaded hole, but is not limited thereto. A bolt is inserted into the third connecting hole 232 and connected by screwing. In other embodiments, the inner wall of the third connecting hole 232 can be smooth without threads.

[0090] In some embodiments, the third positioning surface 231 is arranged around the third connecting hole 232. In this way, the positioning and connecting effects of the fourth positioning part 23 are ensured.

[0091] In some embodiments, the area of the third positioning surface 231 is greater than the area of the third connecting hole 232, so as to increase the fitting area of the third positioning surface 231 in the third direction Z.

[0092] In some embodiments, as shown in Figure 1 and Figure 2 , the fourth positioning part 23 includes a connecting part and a second mounting lug. The connecting part extends in the third direction Z, and the second mounting lug extends in the first direction X. One end of the connecting part is connected to the bracket 10, and the other end of the connecting part is connected to the second mounting lug. The second mounting lug includes the third positioning surface 231 and the third connecting hole 232.

[0093] In some embodiments, the first positioning part 20, the third positioning part 22, and the fourth positioning part 23 can include metal materials such as aluminum, so as to ensure that they have good strength.

[0094] Therefore, as shown in Figure 1 and Figure 2 , for the laser radar assembly 200 composed of the laser radar 400 and the bracket 10, by adding the first positioning part 20, the third positioning part 22, and the fourth positioning part 23, the positioning and mounting of the laser radar assembly 200 in the first direction X and the third direction Z are realized, and the positioning accuracy of the laser radar assembly 200 mounted on the vehicle 600 is improved.

[0095] In some embodiments, as shown in Figure 3 and Figure 5 , the decorative plate 30 further includes a fifth positioning part 24. The fifth positioning part 24 is fitted with the fourth positioning part 23 in the third direction Z, and is used to realize the positioning of the decorative plate 30 and the laser radar 400 in the third direction Z. In this way, the positioning of the decorative plate 30 and the laser radar 400 in the third direction Z is realized through the surface fitting between the fifth positioning part 24 and the fourth positioning part 23.

[0096] In some embodiments, as shown in Figure 5 , the fifth positioning part 24 includes a fourth positioning surface 241 facing the third direction Z. The fourth positioning surface 241 of the fifth positioning part 24 is fitted with the third positioning surface 231 of the fourth positioning part 23, so as to realize the positioning between the fifth positioning part 24 and the fourth positioning part 23.

[0097] In some embodiments, as shown in Figure 5 The fifth positioning part 24 further comprises a fourth connecting hole 242. The fourth connecting hole 242 penetrates the fifth positioning part 24 along the third direction Z. In this way, the fifth positioning part 24 not only plays a positioning role, but also can play a connecting role.

[0098] In some embodiments, as shown in Figure 5 The fourth positioning surface 241 is arranged around the fourth connecting hole 242. In this way, the positioning and connecting effects of the fifth positioning part 24 are ensured.

[0099] In some embodiments, the area of the fourth positioning surface 241 is different from the area of the third positioning surface 231, which reduces the difficulty of fitting between the fourth positioning surface 241 and the third positioning surface 231. Exemplarily, the area of the fourth positioning surface 241 is greater than the area of the third positioning surface 231.

[0100] In some embodiments, the area of the fourth positioning surface 241 is greater than the area of the fourth connecting hole 242.

[0101] In some embodiments, the fourth positioning surface 241 can comprise a plane, but is not limited thereto. In other embodiments, the fourth positioning surface 241 can also comprise a curved surface.

[0102] In some embodiments, the fifth positioning part 24 is located on the top wall of the accommodating cavity 301. In this way, the positioning between the fourth positioning part 23 and the top wall of the decorative plate 30 can be realized through the fifth positioning part 24.

[0103] In some embodiments, the fifth positioning part 24 can comprise a snap spring nut. The snap spring nut is detachably mounted on the top wall of the accommodating cavity 301.

[0104] In some embodiments, as shown in Figure 5 and Figure 6 and Figure 8 The laser radar mounting bracket 100 further comprises a sixth positioning part 25. The sixth positioning part 25 is connected with the third positioning part 22 to realize the positioning of the laser radar 400 in the third direction Z. In this way, the sixth positioning part 25 cooperates with the third positioning part 22 to realize the positioning of the laser radar 400 in the third direction Z.

[0105] In some embodiments, the sixth positioning part 25 is provided with a notch 252 in the second direction X. In this way, the notch 252 can reduce the risk of shrinkage of the sixth positioning part 25.

[0106] In some embodiments, the second positioning part 21 is arranged offset from the sixth positioning part 25 in the first direction X. In this way, the risk of assembly interference between the first positioning part 20 and the third positioning part 22 of the laser radar assembly 200 and the second positioning part 21 and the sixth positioning part 25, respectively, is reduced.
