[0034] See also Figure 1 An embodiment of the present invention provides a support device 10 for a vehicle-mounted laser radar, which is used to be installed on a vehicle-mounted laser radar 600, so as to facilitate the installation of the vehicle-mounted laser radar 600 and to adjust the pitch angle of the vehicle-mounted laser radar 600.

[0035] See also Figure 1 and Figure 2 The bracket device 10 for the vehicle-mounted laser radar includes a first bracket 100, a second bracket 200 and an adjustment component 300. The first bracket 100 is used to be fixedly connected to the vehicle-mounted laser radar 600. The second bracket 200 is used to be rotatably connected to the vehicle-mounted laser radar 600, and the second bracket 200 is used to be installed on the vehicle. The adjustment component 300 is arranged between the first bracket 100 and the second bracket 200, and is used to adjust the pitch angle of the first bracket 100 relative to the second bracket 200, thereby adjusting the pitch angle of the vehicle-mounted laser radar 600.

[0036] See also Figure 1 , Figure 2 and Figure 6 The first bracket 100 includes a first mounting portion 110, and a plug hole 120 is provided on the first mounting portion 110. The second bracket 200 includes a second mounting portion 210 arranged opposite to the first mounting portion 110, and a pitch adjustment hole 220 is provided on the second mounting portion 210. The application does not limit the size of the plug hole 120 and the pitch adjustment hole 220, and the size can be set according to the use requirements.

[0037] See also Figure 1 and Figure 2 In this embodiment, the pitch adjustment hole 220 is a circular hole, and the pitch adjustment hole 220 is concentrically arranged with the insertion hole 120 , which can ensure the installation accuracy of the adjustment screw 310 .

[0038] See also Figure 1 , Figure 2 , Figure 4 and Figure 6The adjustment assembly 300 includes an adjustment screw 310, a locking nut 320 and an adjustment spring 330. The adjustment screw 310 is inserted into the insertion hole 120 and the pitch adjustment hole 220 and is fastened by the locking nut 320 to adjust the pitch angle of the first bracket 100. Specifically, the adjustment screw 310 is inserted into the first mounting portion 110 and the second mounting portion 210. An adjustment thread that is threadably matched with the locking nut 320 is disposed at one end of the adjustment screw 310 close to the second mounting portion 210. The locking nut 320 is located on a side of the second mounting portion 210 away from the first mounting portion 110.

[0039] See also Figure 1 , Figure 2 and Figure 4 When the pitch angle of the first bracket 100 needs to be adjusted, the first mounting portion 110 and the second mounting portion 210 can be moved closer to or farther from each other by tightening or loosening the locking nut 320, and since the second bracket 200 can be rotatably connected to the vehicle-mounted laser radar 600, the first bracket 100 and the vehicle-mounted laser radar 600 fixedly connected to the first bracket 100 can both rotate relative to the second bracket 200, thereby adjusting the pitch angle of the first bracket 100. By setting the locking nut 320, the adjusting screw 310 can be fastened between the first mounting portion 110 and the second mounting portion 210, and by tightening or loosening the locking nut 320, the pitch angle of the first bracket 100 can be adjusted. It should be understood that the pitch angle is the angle between the horizontal plane and the vehicle-mounted laser radar 600.

[0040] See also Figure 1 , Figure 2 and Figure 3 The adjusting spring 330 is sleeved on the adjusting screw 310 and is arranged between the first mounting portion 110 and the second mounting portion 210. The two ends of the adjusting spring 330 can respectively abut against the first mounting portion 110 and the second mounting portion 210. By arranging the adjusting spring 330 between the first mounting portion 110 and the second mounting portion 210, the adjusting spring 330 can provide elastic force for the first mounting portion 110 and the second mounting portion 210 at the same time, which can not only make the connection between the adjusting screw 310 and the locking nut 320 and the first mounting portion 110 and the second mounting portion 210 more tightly, but also play a role of shock absorption, which can effectively prevent the adjusting screw 310 and the locking nut 320 from loosening.

[0041] See also Figure 1 and Figure 3It should be noted that: according to the force analysis of the bracket device 10 for the vehicle-mounted laser radar, when the vehicle is in vibration, bumps and other working conditions during driving, the bracket device 10 for the vehicle-mounted laser radar will be subjected to frequent impact force Fg in the direction of gravity. The vibration generated by the vehicle during driving may cause the locking nut 320 to loosen, but the component force F1 generated by the impact force Fg will increase the positive pressure on the locking nut 320, and as the inclination α increases, the component force F1 generated by the impact force Fg will be greater, so that the friction force between the threads of the locking nut 320 will be greater, so that the locking nut 320 is less likely to loosen. It should be further noted that the direction of the component force F1 generated by the impact force Fg is the axial direction of the adjusting screw 310. The direction of the component force F2 generated by the impact force Fg is the vertical direction of the axial direction of the adjusting screw 310. α refers to the angle between the impact force Fg and the component force F2 generated by the impact force Fg.

[0042] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 According to some embodiments of the present application, optionally, the bracket device 10 for the vehicle-mounted laser radar also includes a limiting component 400 for limiting the position of the adjusting screw 310 relative to the first bracket 100 and the locking nut 320 relative to the second bracket 200.

The second end is formed with a first abutting portion 412 abutting against the first limiting portion 420. Specifically, the inner diameter of the first embedded portion 411 is greater than the diameter of the adjusting screw 310. The first abutting portion 412 matches the shape of the first limiting portion 420. More specifically, the first abutting portion 412 forms a spherical fit with the first limiting portion 420, which does not hinder the rotation of the adjusting screw 310.

More specifically, the second abutting portion 432 forms a spherical fit with the second limiting portion 440, which does not hinder the rotation of the adjusting screw 310.

[0045] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 In another embodiment, the limiting assembly 400 includes a first limiting ring 410 inserted into the adjusting screw 310, a first limiting portion 420 formed at one end of the adjusting screw 310, a second limiting ring 430 inserted into the adjusting screw 310, and a second limiting portion 440 formed at one end of the locking nut 320.

The second end is formed with a first abutting portion 412 abutting against the first limiting portion 420. The second limiting ring 430 includes a third end and a fourth end disposed oppositely, and the third end is formed with a second embedded portion 431 embedded in the pitch adjustment hole 220. The fourth end is formed with a second abutting portion 432 abutting against the second limiting portion 440.

[0046] See also Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present application, optionally, the second bracket 200 is hinged to the vehicle-mounted laser radar 600. Specifically, the second bracket 200 also includes a horizontal support portion 230 and two vertical connection portions 240, and the horizontal support portion 230 and the second mounting portion 210 are perpendicular to each other. The two vertical connection portions 240 are respectively arranged at two opposite ends of the horizontal support portion 230, and the two vertical connection portions 240 are respectively connected to the vehicle-mounted laser radar 600 through the rotating assembly 500. More specifically, the vehicle-mounted laser radar 600 is located between the two vertical connection portions 240.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Figure 7 In one embodiment, the rotating assembly 500 includes a through hole 510 opened on the vertical connection part 240 and a rotating screw 520 fixedly connected to the vehicle-mounted laser radar 600, and the rotating screw 520 is inserted into the through hole 510. Specifically, the aperture of the through hole 510 is larger than the diameter of the rotating screw 520. The rotating screw 520 has a nut and a stud, which can prevent the vertical connection part 240 from coming out of the stud. More specifically, the rotating screw 520 is threadedly connected to the vehicle-mounted laser radar 600.

[0048] In another embodiment, the rotating assembly 500 includes a through hole 510 formed on the vertical connection part 240 and a rotating shaft fixedly connected to the vehicle-mounted laser radar 600, and the rotating shaft is passed through the through hole 510; a protrusion is formed at one end of the rotating shaft away from the vehicle-mounted laser radar 600 to prevent the vertical connection part 240 from escaping from the rotating shaft. Specifically, the aperture of the through hole 510 is larger than the diameter of the rotating shaft and smaller than the diameter of the protrusion.

[0049] See also Figure 1 and Figure 2 The first bracket 100 includes a horizontal connection portion 130 connected to the vehicle-mounted laser radar 600, and the horizontal connection portion 130 is perpendicular to the first mounting portion 110. Specifically, the first mounting portion 110 and the second mounting portion 210 are parallel to each other and spaced apart. The horizontal connection portion 130 and the horizontal support portion 230 are parallel to each other.

[0050] See also Figure 1 , Figure 2 and Figure 8 According to some embodiments of the present application, the second bracket 200 is optionally hinged to the vehicle, so that the second bracket 200 can rotate relative to the vehicle and can be fixed relative to the vehicle by a fastening assembly. It should be noted that when the second bracket 200 rotates relative to the vehicle, the vehicle-mounted laser radar 600 rotates with the second bracket 200, thereby adjusting the yaw angle of the vehicle-mounted laser radar 600.

[0051] It should be understood that the vehicle-mounted laser radar 600 is at a certain angle, and the angle between the certain angle and the set angle is the yaw angle of the vehicle-mounted laser radar 600. The angle between the certain angle and the set angle is set as b. If the vehicle-mounted laser radar 600 needs to be adjusted from a certain angle to the set angle, it is only necessary to rotate the second bracket 200 relative to the vehicle by b, thereby achieving the adjustment of the yaw angle of the vehicle-mounted laser radar 600.

The fastener is passed through the yaw adjustment hole 251 and is fixedly connected to the vehicle to fix the second bracket 200 to the vehicle. Specifically, the fastener is threadedly connected to the vehicle. It should be understood that when it is necessary to adjust the rotation angle of the second bracket 200 relative to the vehicle, the fastener is loosened so that the fastener is separated from the vehicle, so that the second bracket 200 can rotate relative to the vehicle. When the position of the second bracket 200 is adjusted, the fastener is tightened so that the fastener fixes the position of the second bracket 200. Exemplarily, the fastener is a screw.

[0053] In this embodiment, a plurality of third mounting portions 250 are provided on the second bracket 200. Specifically, three third mounting portions 250 are provided on the second bracket 200, wherein one third mounting portion 250 is connected to the horizontal support portion 230 and is perpendicular to the horizontal support portion 230. The other two third mounting portions 250 are respectively connected to the two vertical connection portions 240 and are perpendicular to the vertical connection portions 240.

[0054] The second bracket 200 is further provided with a fourth mounting portion 260, and a hinge hole 261 is provided on the fourth mounting portion 260. The second bracket 200 is hinged to the vehicle through the hinge hole 261. The fourth mounting portion 260 and the horizontal support portion 230 are perpendicular to each other.

[0055] See also Figure 1 and Figure 2 The second mounting portion 210 is also provided with a plurality of weight-reducing holes 270, which can reduce weight. For example, the weight-reducing holes 270 can be waist-shaped holes, or circular holes, which are not limited in the present application, as long as the weight-reducing effect can be achieved.

[0056] In the vehicle-mounted laser radar bracket device 10 of the present application, the vehicle-mounted laser radar 600 is located between the two vertical connecting parts 240, that is, the first mounting part 110 of the first bracket 100, the second mounting part 210 of the second bracket 200 and the adjustment component 300 are all located above the vehicle-mounted laser radar 600, which increases the adjustment space and makes the adjustment convenient and quick.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
