[0022] This application provides a laser radar mounting bracket for an autonomous vehicle, such as Figure 1 As shown, including:

[0023] The vehicle body connecting member 100 is installed on the vehicle roof and is detachably connected to the top of the vehicle body;

[0024] The laser radar support member 200 is vertically mounted on the vehicle body connector 100 and is used to mount and support the laser radar 300. The support member 200 includes a vertical pole 210, a bent portion 220, and a suspension rod 230. One end of the suspension rod 230 is connected to the end of the vertical pole 210 away from the vehicle body connector 100 via the bent portion 220. The suspension rod 230 is used to suspend the laser radar 300 and is flexibly connected to the laser radar 300 for shock absorption and buffering.

[0025] The vehicle body connector 100 is further provided with an antenna mushroom head mounting position 400 , and the antenna mushroom head mounting position 400 is symmetrically arranged on both sides of the vertical pole 210 .

[0026] The laser radar mounting bracket for an autonomous vehicle of the present application has a laser radar support member 200 vertically positioned above the vehicle roof through a vehicle body connector 100, and a laser radar 300 suspended on the laser radar support member 200 to achieve 360° no-blind-angle monitoring of the vehicle body. It can automatically draw maps to accurately locate and avoid obstacles in signal-blocking scenarios, provide key environmental information for the autonomous driving system, and achieve high-precision positioning. The laser radar 300 and the laser radar support member 200 are in soft contact through a silicone pad to achieve a shock-absorbing and buffering effect, thereby improving the stability of the laser radar and thus improving driving safety and reliability.

[0027] Since the laser radar has a relatively high requirement for shock absorption, in order to avoid the laser radar from vibrating significantly due to bumpy roads or large shaking of the vehicle when starting or braking during driving, for example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 2 As shown, a mounting plate 240 is fixedly provided on the bottom surface of the suspension rod 230, mounting holes 241 are provided at the four corners of the mounting plate 240, and a silicone pad 242 is provided at the mounting hole 241. The laser radar 300 is fixedly connected to the mounting plate 240 by bolts passing through the mounting holes 241 and the silicone pad 242, and the silicone pad 242 realizes soft contact between the laser radar 300 and the laser radar support 100.

[0028] According to the above embodiment, the present application adds a silicone pad 242 between the laser radar 300 and the mounting plate 240, so that the laser radar 300 and the mounting plate 240 are in soft contact through the silicone pad 242, which can play a role in buffering and shock absorption, and avoid direct rigid contact between the laser radar 300 and the mounting plate 240. When encountering bumpy road conditions, the laser radar 300 will vibrate violently, affecting the normal use of the laser radar. The present application can ensure the normal function of the laser radar, reduce losses, and extend the service life of the laser radar.

[0029] For example, in the laser radar mounting bracket for an autonomous vehicle provided in one embodiment, the mounting plate 240 is fixed to the bottom surface of the suspension rod 230 by welding.

[0030] According to the above embodiment, the mounting plate 240 is welded to the suspension rod 230 to form an integrated structure, thereby enhancing the connection strength and preventing the mounting plate 240 from shaking.

[0031] For example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 1 As shown, the vehicle body connector 100 includes:

[0032] Two parallel and spaced apart vehicle body connecting rods 110, the vehicle body connecting rods 110 being used for detachable connection to the vehicle roof;

[0033] A plurality of bottom bars 120 are vertically connected between the two vehicle body connecting bars 110 .

[0034] In order to realize the detachable connection between the vehicle body connector 100 and the vehicle roof, for example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 1 As shown, the vehicle body connector 100 further includes a clamping assembly 130 provided on the bottom surface of the vehicle body connecting rod 110 near both ends, and the clamping assembly 130 includes:

[0035] A base 131 is used to support the vehicle body connecting rod 110 and ensure a distance between the vehicle body connecting rod 110 and the vehicle roof;

[0036] The hook 132 is suspended outside the base 131 and is used for fixed connection with the vehicle body.

[0037] According to the above embodiment, by providing a base 131 on the bottom surface of the body connecting rod 110, the body connecting rod 110 can be stably mounted on the roof, and a distance can be provided between the body connecting rod 110 and the roof. The distance between the body connecting rod 110 and the roof forms an installation space for accommodating the bottom bar 120, that is, in the present application, the bottom bar 120 is installed on the bottom surface of the body connecting rod 110, and through holes for bolts to pass through are provided on the bottom bar 120 and the body connecting rod 110. The bottom bar 120 is fixedly connected to the body connecting rod 110 by bolts, and the bolt rod passes through the through holes on the bottom bar 120 and the body connecting rod 110 and passes out from the bottom surface of the bottom bar 120. The distance between the body connecting rod 110 and the roof needs to be greater than the length of the bolt rod, so as to prevent the exposed end of the bolt rod from scratching the roof.

[0038] The laser radar support member 200 stands vertically above the roof through the body connecting member 100. For example, in the laser radar mounting frame for an autonomous driving vehicle provided in one embodiment, three bottom rods 120 are vertically connected between the two body connecting rods 110, one of which is located at the center of the body connecting rod 110, recorded as the center bottom rod, and the other two are symmetrically distributed on both sides of the center bottom rod. The vertical rod 210 is vertically arranged at the center position of the center bottom rod, and the antenna mushroom head mounting position 400 is provided at the center position of the bottom rod on both sides of the center bottom rod.

[0039] Since the laser radar support member 200 is vertically positioned above the vehicle roof, in order to improve the stability of the laser radar support member 200, for example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 1As shown, four bottom bars 120 are vertically connected between the two body connecting bars 110, wherein the two bars close to the normal center line of the body connecting bar 110 are marked as inner bottom bars 121, and the other two bars are marked as outer bottom bars 122. The laser radar support member 200 also includes a bottom support bar 250, and the two ends of the bottom support bar 250 are respectively connected to the center of the inner bottom bar 121, the vertical bar 210 is vertically arranged at the center position of the bottom support bar 250, and the antenna mushroom head mounting position 400 is provided at the center position of the outer bottom bar 122.

[0040] While improving the stability of the laser radar support 200, in order to reduce tooling and parts, for example, in the laser radar mounting frame for an autonomous driving vehicle provided in one embodiment, the two bottom bars 120 are vertically connected between the two body connecting bars 110, and the two bottom bars 120 are symmetrically distributed on both sides of the normal center line of the body connecting bar 110. The laser radar support 200 also includes a bottom support bar 250, and the two ends of the bottom support bar 250 are respectively connected to the centers of the two bottom bars 120, and the vertical pole 210 is vertically arranged at the center position of the bottom support bar 250, and the antenna mushroom head mounting position 400 is provided at both ends of the bottom support bar 250.

[0041] According to the above embodiment, by setting a bottom support rod 250 at the bottom of the laser radar support member 200, and the two ends of the bottom support rod 250 are respectively connected to the bottom rod 120 by bolts, the stability of the laser radar support member 200 can be enhanced, so that the laser radar can stand more firmly above the roof.

[0042] In order to facilitate the wiring of the laser radar / data line and avoid the exposure of the wires / data lines, for example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 3 As shown, the interior of the vertical pole 210 is hollow, and a wire hole 211 for the laser radar wire to pass through is provided at the end of the vertical pole 210 near the bending portion 220. The laser radar wire passes through the wire hole 211 and exits from the through hole 212 at the bottom of the vertical pole 210.

[0043] According to the above embodiment, by setting the vertical pole 210 as a hollow structure, weight reduction is achieved and the vehicle load is reduced. At the same time, a wire passing structure is formed for the laser radar wires / data cables to pass through, which is convenient for wiring. The lines are wrapped inside the vertical pole 210 to prevent the wires from being exposed to the sun or being damaged by wind and rain, thereby improving safety and making the structure neat and beautiful.

[0044] It should be noted that the body connecting rod 110 and the bottom rod 120 in the body connecting part 100 in this application and the vertical rod 210, the bending part 220, the suspension rod 230 and the bottom support rod 240 in the laser radar support part 200 are all hollow structures to reduce their own weight, be lightweight and portable, reduce the installation labor intensity, and also reduce the vehicle load.

[0045] In order to improve the positioning accuracy of the laser radar, for example, in the laser radar mounting bracket for the autonomous driving vehicle provided in one embodiment, Figure 1 As shown, the antenna mushroom head mounting position 400 is a bolt hole, and the distance between two antenna mushroom head mounting positions 400 is not less than 0.8m.

[0046] According to the above embodiment, the antenna mushroom head 500 is detachably connected to the vehicle body connector 100 through a bolt hole, which is easy to install. The antenna mushroom head is used to receive signals. If the distance between the two antenna mushroom heads is too small, the positioning is inaccurate. By limiting the distance between the two antenna mushroom head mounting positions 400, the positioning accuracy of the laser radar can be improved.

[0047] Although the implementation scheme of the present application has been disclosed as above, it is not limited to the applications listed in the description and implementation mode. It can be fully applied to various fields suitable for the present application. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present application is not limited to the specific details and illustrations shown and described herein.
