Technical Field

[0001] This utility model relates to the field of laser radar mounting technology, specifically an adjustable-angle laser radar mount. Background Technology

[0002] With the rapid development of artificial intelligence technology, application scenarios such as autonomous driving, facial recognition, and 3D photography are gradually maturing. LiDAR is an important environmental perception device for autonomous driving, and in order to improve the detection effect of LiDAR, it is connected to the drive device.

[0003] Existing similar lidar driving devices have poor adjustability, making it difficult to adjust the lidar position as needed. Furthermore, the lidar is not easy to disassemble and assemble quickly, which can affect the efficiency of subsequent disassembly, assembly, and maintenance.

[0004] To address this, we propose an adjustable-angle lidar mount. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle lidar mount, comprising a fixed base, a rotating shaft rotatably connected to the center of the top of the base, a first motor fixedly installed inside the base on one side of the rotating shaft, a worm gear rotatably connected inside the fixed base to the rear of the first motor, a worm wheel fixedly installed in the center of the rotating shaft inside the fixed base, the worm wheel meshing with the worm gear, the output end of the first motor fixedly installed with one end of the worm gear, a rotating seat integrally connected to the top of the rotating shaft, an arc-shaped groove formed on the top of the rotating seat, a second motor fixedly installed inside the rotating shaft, a rotating rod rotatably connected to the top of the rotating shaft above the second motor, the output end of the second motor being drively connected to the rotating rod, a transmission gear path fixedly installed in the center of the rotating rod, a sliding seat slidably connected inside the arc-shaped groove, an arc-shaped rack fixedly installed on the arc surface at the bottom of the sliding seat, the arc-shaped rack meshing with the top of the transmission gear path, and a mounting seat slidably disposed on the top of the sliding seat.

[0007] Optionally, the interior of the rotating shaft is hollow, the top of the hollow groove inside the rotating shaft extends through the bottom of the arc-shaped groove, and pressure blocks located on both sides of the arc-shaped groove are fixedly installed on the top of the rotating seat.

[0008] Optionally, the pressure block is in close sliding contact with the arc-shaped protrusions on both sides of the sliding seat, and the two pressure blocks are symmetrically arranged on both sides of the sliding seat.

[0009] Optionally, a first bevel gear is fixedly installed at the output end of the second motor, and a second bevel gear located on one side of the transmission gear is fixedly installed on the rotating rod, with the second bevel gear meshing with the first bevel gear.

[0010] Optionally, the top of the sliding seat is provided with a fixing groove, and the mounting seat includes a connecting block that is fixedly installed inside the fixing groove. The top of the connecting block is integrally provided with a mounting top plate, and the mounting top plate is fixedly installed with the lidar.

[0011] Optionally, the connecting block has fixing grooves on its front and rear sides, the fixing grooves are connected through the top of the mounting plate, and the mounting plate has threaded posts at its four corners.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This adjustable lidar mount uses a first motor to drive a worm gear to rotate the shaft 360° horizontally, and a second motor to drive a sliding seat along an arc-shaped groove via gear transmission to adjust the pitch angle. This significantly improves the adjustability of the device, effectively expands the lidar's detection range, and reduces blind spots. Furthermore, the mounting base slides into the fixed groove of the sliding seat via a connecting block, and with the help of threaded posts, the lidar can be quickly installed and removed, significantly improving the efficiency of subsequent maintenance and replacement.

A transmission gear circuit is fixedly installed in the middle of the device. A sliding seat 12 is slidably connected inside the arc-shaped groove 7. An arc-shaped rack 13 is fixedly installed on the arc surface at the bottom of the sliding seat 12. The arc-shaped rack 13 meshes with the top of the transmission gear circuit. A mounting seat 14 is slidably installed on the top of the sliding seat 12. The first motor 5 drives the worm gear 6 to rotate the worm wheel 4, thereby realizing the horizontal 360° rotation of the rotating shaft 2. The second motor 9 drives the sliding seat 12 to slide along the arc-shaped groove 7 through gear transmission to realize the pitch angle adjustment, which greatly improves the adjustability of the device, effectively expands the detection range of the lidar, and reduces the detection blind zone. Furthermore, the mounting seat 14 slides with the fixing groove of the sliding seat 12 through the connecting block 1401. With the help of the threaded column 1404, the installation and disassembly of the lidar can be completed quickly, which significantly improves the efficiency of subsequent maintenance and replacement.

[0019] The interior of the rotating shaft 2 is hollow, and the top of the hollow groove inside the rotating shaft 2 passes through the bottom of the arc-shaped groove 7. The top of the rotating seat 3 is fixedly installed with pressure blocks 8 located on both sides of the arc-shaped groove 7.

[0020] The pressure block 8 and the arc-shaped protrusions on both sides of the sliding seat 12 are in tight sliding contact. The two pressure blocks 8 are symmetrically arranged on both sides of the sliding seat 12. The pressure blocks 8 on both sides form a limiting and tight contact with the arc-shaped protrusions of the sliding seat 12. The worm gear 4 and worm 6 transmission have self-locking characteristics. After adjustment, the angle is not easy to deviate, ensuring the position accuracy of the lidar when it is working.

[0021] The output end of the second motor 9 is fixedly mounted with a first bevel gear 15, and the rotating rod 10 is fixedly mounted with a second bevel gear 16 located on one side of the transmission gear 11. The second bevel gear 16 meshes with the first bevel gear 15.

[0022] The top of the sliding seat 12 is provided with a fixing groove, and the mounting seat 14 includes a connecting block 1401 that is fixedly installed inside the fixing groove. The top of the connecting block 1401 is integrally provided with a mounting top plate 1402, and the mounting top plate 1402 is fixedly installed with the lidar.

[0023] The connecting block 1401 has fixing grooves 1403 on both the front and rear sides. The fixing grooves 1403 are connected through the top of the mounting plate 1402. Threaded posts 1404 are provided at the four corners of the top of the mounting plate 1402.

[0024] The bottom of the mounting plate 1402 is abutted against the top of the sliding seat 12, and the size of the mounting plate 1402 is larger than the size of the top of the sliding seat 12.

[0025] Working principle: First, fix the mounting base 1 on the designated plane. Then, pre-install the lidar onto the mounting plate 1402 using the threaded post 1404. Next, push the connecting block 1401 of the mounting base 14 into the sliding seat 12 along the fixing groove to complete the quick pre-installation and fixing of the lidar. When the lidar angle needs to be adjusted, start the first motor 5, which drives the worm wheel 4 to rotate via the worm gear 6, causing the rotating shaft 2 and rotating seat 3 to rotate horizontally as a whole, adjusting the lidar to the desired horizontal orientation. Then, start the second motor 9, which drives the rotating rod 10 to rotate via the bevel gear transmission. The meshing of the transmission gear with the arc-shaped rack 13 causes the sliding seat 12 to slide along the arc-shaped groove 7, completing the precise adjustment of the lidar's pitch angle. For subsequent maintenance or replacement of the lidar, simply slide the mounting base 14 out of the fixing groove of the sliding seat 12 for quick disassembly.
