Description

Technical Field

[0001] This utility model relates to the field of lidar mounting technology, specifically an adjustable lidar mounting. Background Technology

[0002] In fields such as autonomous driving and environmental detection, LiDAR, as a core sensing device, often needs to be mounted on mobile vehicles such as automobiles. The ease and stability of its installation, fixation, and position adjustment directly affect the detection accuracy and efficiency. Currently, most LiDAR mounting brackets on the market are one-piece structures, and the fixing methods mostly rely on welding or multiple sets of bolts. During installation, special tools are required to align and adjust the bracket with the car's roof rack, which is cumbersome and time-consuming, and subsequent disassembly and maintenance are difficult.

[0003] Meanwhile, the position adjustment function of existing mounting brackets has significant limitations: some brackets can only achieve fine-tuning of a single angle, which cannot meet the needs of large-area lateral detection by lidar; some brackets with lateral adjustment function mostly use manual sliding block adjustment, which has low adjustment accuracy and is laborious, and lacks a reliable limiting structure after adjustment. During vehicle movement, bumps can easily cause the lidar position to shift, affecting the accuracy of detection data. In addition, most brackets do not have protective structures for the lidar body. During long-term use, vibration and friction can easily cause wear and tear on the precision components inside the lidar, shortening the equipment's lifespan and making it difficult to adapt to the diverse needs of actual application scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to the following: Figure 1-3 , An adjustable lidar mounting bracket includes: U-shaped plate 1 and blocking plate 2, the blocking plate 2 is fixedly installed on both sides of the U-shaped plate 1, and two sliding rods 3 are fixedly installed between the two blocking plates 2; The slide plate 4 and the clamping plate 5 are slidably connected to the outside of the slide rod 3, and the clamping plate 5 is fixedly installed on the outside of the blocking plate 2, and the internal thread of the clamping plate 5 is connected with a locking bolt 6; The L-shaped plate 7 and the electric telescopic rod 8 are fixedly installed on the top of the slide plate 4, and the electric telescopic rod 8 is fixedly installed on the inner side of the L-shaped plate 7. The output end of the electric telescopic rod 8 is fixedly installed with a limit post 9. The motor and drive wheel 10 are provided. The motor is located inside the slide plate 4, and the drive wheel 10 is fixedly installed at the output end of the motor and is adapted to the U-shaped plate 1. The placement plate 11 and the lidar body 12 are provided. The placement plate 11 is fixedly installed between the two L-shaped plates 7, and the lidar body 12 is located inside the placement plate 11. The horizontal plate 13 and the support column are fixedly installed on the outside of the L-shaped plate 7. The horizontal plate 13 is rotatably connected to the outside of the support column, and a fixing bolt 14 threadedly connected to the support column is provided inside the horizontal plate 13. Specifically, the foundation is fixed: the U-shaped plate 1 serves as the main frame of the device, and the blocking plates 2 on both sides are used not only to fix the two parallel sliding rods 3, but also to provide support for the subsequent installation of components; the clamping plate 5 on the outside of the blocking plate 2, together with the locking bolt 6 with internal thread connection, can be tightly attached to the car roof rack by turning the locking bolt 6, thereby completing the fixation of the entire device on the roof rack; Lateral adjustment drive: The slide plate 4 is slidably connected to the outside of the slide bar 3. The motor inside drives the drive wheel 10 at the output end to rotate. The drive wheel 10 is adapted to the U-shaped plate 1. When rotating, it moves along the inner wall of the U-shaped plate 1, thereby driving the slide plate 4 to slide laterally along the slide bar 3. The L-shaped plate 7 at the top of the slide plate 4 fixes the placement plate 11. The laser radar body 12 inside the placement plate 11 moves synchronously with the slide plate 4 to realize lateral position adjustment. Adjustable limit locking: When the electric telescopic rod 8 on the inner side of the L-shaped plate 7 needs to be limited, the limiting post 9 at its output end moves closer to and fits against the slide rod 3, thereby increasing the friction to limit the sliding of the slide plate 4; at the same time, the horizontal plate 13 on the outer support column of the L-shaped plate 7 can be rotated to adjust the angle and then connected to the support column by the threaded fixing bolt 14, which further strengthens the connection stability between the L-shaped plate 7 and the slide plate 4 and ensures the stability of the position of the lidar body 12. In this embodiment: the slide bar 3 and the blocking plate 2 are an integrated structure, and the two slide bars 3 are symmetrically distributed about the central axis of the U-shaped plate 1; Specifically, the sliding rod 3 and the blocking plate 2 adopt an integrated structure, which avoids gaps or loosening problems during the assembly of the two, and ensures that the sliding rod 3 will not deviate when subjected to frictional forces such as when the sliding plate 4 slides. At the same time, the two sliding rods 3 are symmetrically distributed about the central axis of the U-shaped plate 1, so that the force on both sides of the sliding plate 4 is uniform. During the sliding process, the sliding rods 3 on both sides will not tilt due to asymmetry, ensuring the stability of the sliding plate 4 when it drives the lidar body 12 to move laterally, and reducing the impact of sliding deviation on the detection accuracy of the lidar. In this embodiment: the limiting post 9 is made of rubber, and the outer side of the limiting post 9 is provided with anti-slip texture, which is in contact with the outer side of the slide rod 3; Specifically, the limiting post 9 is made of rubber, which has good elasticity and friction. Compared with hard materials, it can fit more tightly to the surface of the slide bar 3. At the same time, the anti-slip texture on the outside of the limiting post 9 further increases the contact friction with the slide bar 3. When the electric telescopic rod 8 pushes the limiting post 9 to fit the slide bar 3, the elastic deformation of the rubber material and the physical interlocking of the anti-slip texture work together to greatly improve the limiting stability and effectively prevent the slide plate 4 from sliding unexpectedly when the vehicle is bumpy or when the lidar is vibrating, ensuring that the lidar body 12 is reliably locked in position. In this embodiment: the outer side of the drive wheel 10 is fitted with a wear-resistant rubber sleeve, the thickness of the wear-resistant rubber sleeve is 3-5mm, and the wear-resistant rubber sleeve is in close contact with the inner wall of the U-shaped plate 1. Specifically, the wear-resistant rubber sleeve on the outer side of the drive wheel 10 has high wear resistance, which can reduce the wear caused by long-term friction between the drive wheel 10 and the inner wall of the U-shaped plate 1, and extend the service life of the drive wheel 10. At the same time, the elasticity of the wear-resistant rubber sleeve allows it to make close contact with the inner wall of the U-shaped plate 1, avoiding the free-spinning phenomenon caused by the gap between the drive wheel 10 and the U-shaped plate 1, ensuring that the power of the motor can be stably transmitted to the drive wheel 10, thereby driving the slide plate 4 to slide smoothly, and ensuring the smoothness and accuracy of the lateral adjustment of the lidar body 12. In this embodiment: the placement plate 11 has an internal mounting groove that is adapted to the lidar body 12, and the inner wall of the mounting groove is covered with a cushioning sponge pad with a thickness of 2-4mm. Specifically, the mounting groove inside the placement plate 11, which is adapted to the lidar body 12, can position the lidar body 12 and prevent it from shifting laterally or longitudinally within the placement plate 11. At the same time, the 2-4mm thick buffer sponge pad on the inner wall of the mounting groove can effectively absorb vibrations or external impacts such as minor collisions during vehicle operation, reduce the impact of vibrations on the precision components inside the lidar body 12, avoid deviations in lidar detection data due to vibrations, and ensure its working accuracy and service life. In this embodiment: there are two horizontal plates 13, which are respectively disposed at the upper and lower ends of the outer support column of the L-shaped plate 7, and the length of the horizontal plate 13 is greater than the diameter of the support column; Specifically, two horizontal plates 13 are respectively set at the upper and lower ends of the outer support column of the L-shaped plate 7, forming a fixed structure that clamps from the top and bottom. When the horizontal plate 13 is rotated to fit against the surface of the L-shaped plate 7 or the sliding plate 4, it is connected to the support column by the threaded fixing bolt 14, which can lock the support column from both the top and bottom directions, preventing the support column from bending or rotating due to forces such as the weight of the lidar body 12 or the tension when the sliding plate 4 slides. At the same time, the length of the horizontal plate 13 is greater than the diameter of the support column, ensuring that the horizontal plate 13 has sufficient contact area to fit against the L-shaped plate 7 or the sliding plate 4, further improving the fixing stability and indirectly ensuring the positional stability of the lidar body 12. In this embodiment: an anti-slip knob is fixedly installed at the end of the locking bolt 6, the outer side of the anti-slip knob is provided with a textured surface, and the diameter of the anti-slip knob is larger than the diameter of the rod of the locking bolt 6; Specifically, the anti-slip knob at the end of the locking bolt 6 has a textured surface on its outer side that increases the friction between the hand and the knob, allowing operators to easily turn the locking bolt 6 without tools, thus achieving a tight fit or disassembly between the clamping plate 5 and the car roof rack. At the same time, the diameter of the anti-slip knob is larger than the diameter of the locking bolt 6 rod, which increases the force application area of ​​the hand, reduces the force on the hand when turning, improves operating comfort and efficiency, and ensures that the device can be quickly and securely fixed to the car roof rack. In the embodiment: the U-shaped plate 1 is made of aluminum alloy, and the surface of the U-shaped plate 1 is coated with an anti-rust coating, the thickness of which is 1-2mm; Specifically, the U-shaped plate 1 is made of aluminum alloy, which is lightweight and high-strength. It can meet the structural strength requirements of the device to support the weight of components such as the sliding plate 4 and the lidar main body 12, while reducing the overall weight of the device and avoiding increasing the load on the car roof rack. At the same time, the 1-2mm thick anti-rust coating on the surface of the U-shaped plate 1 can isolate the aluminum alloy surface from air, moisture or external corrosive substances such as acidic components in rainwater and dust, prevent the U-shaped plate 1 from oxidizing and rusting, ensure its structural stability during long-term use, avoid loosening of component connections due to rust, and ensure the normal functioning of the overall device. Working principle: When fixing, twist the locking bolt 6 inside the clamping plate 5 to make the clamping plate 5 fit against the car roof rack and fix the device. When the laser radar body 12 needs to be adjusted laterally, first control the electric telescopic rod 8 inside the L-shaped plate 7 to retract, driving the limiting post 9 away from the slide bar 3. Then start the motor inside the slide plate 4. The motor drives the drive wheel 10 at the output end to rotate along the U-shaped plate 1, thereby driving the slide plate 4 to move laterally along the slide bar 3 between the blocking plates 2. The laser radar body 12 adjusts its position synchronously with the slide plate 4. After the adjustment is in place, turn off the motor and control the electric telescopic rod 8 to operate, so that the limiting post 9 fits against the slide bar 3 to increase friction and restrict the movement of the slide plate 4. At the same time, the horizontal plate 13 on the outer support column of the L-shaped plate 7 can be rotated and connected to the support column by the fixing bolt 14 to further strengthen the structure and ensure the stability of the laser radar body 12.
