Description

Technical Field

[0001] This utility model belongs to the field of lidar, specifically an anti-collision lidar protective shell. Background Technology

[0002] LiDAR is a radar system that uses laser beams to detect the position, velocity, and other characteristics of a target. Its working principle is to send a detection signal to the target, then compare the received signal reflected back from the target with the transmitted signal, and after appropriate processing, obtain relevant information about the target, such as the target's distance, azimuth, altitude, velocity, attitude, and even shape.

[0003] A search revealed a Chinese patent (authorization announcement number CN213581333U) disclosing an explosion-proof housing for a lidar system. This patented technology includes an explosion-proof housing with a front cover on one side, bolted to the housing. An explosion-proof glass is installed in the center of the front cover. A rear cover is located on the other side of the housing, with an opening in its center. A mounting groove is bolted to the lower inner surface of the housing, and a lidar is installed within this groove. Connecting rings are fixedly connected to both sides of the housing, and mounting brackets are provided on the outer sides of these rings. This invention features a reasonable structure, low manufacturing cost, and provides comprehensive protection for the lidar. The angle of the entire explosion-proof housing can be adjusted; after adjustment, simply tightening the bolts secures it, allowing for convenient adjustment of the lidar's angle.

[0004] However, the existing protective housings for lidar are insufficient in terms of protection. When the lidar is hit by an external force, the impact will cause the lidar to vibrate, which can easily damage the internal parts of the lidar. Moreover, most existing lidar protective housings are fixed to the lidar by welding or bolting, which makes it inconvenient to disassemble and unable to maintain the internal lidar in a timely manner. Therefore, this utility model provides a collision-resistant lidar protective housing. Utility Model Content

[0009] Preferably, the unlocking unit includes two sliding shafts, which are symmetrically arranged inside the protective plate and are slidably connected to the protective plate. The two sliding shafts are respectively fixedly connected to two locking blocks. A sliding plate is fixedly connected to one end of each sliding shaft that is close to the other. The sliding plate is slidably connected to the protective plate. A first spring is sleeved on the outer wall of the sliding shaft. One end of the first spring is fixedly connected to the locking block, and the other end of the first spring is fixedly connected to the protective plate.

[0010] Preferably, a plurality of top rods are equidistantly slidably connected to the top of each of the two protective plates, and a dovetail plate is fixedly connected to the top of each of the two sets of top rods.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 5 As shown, this utility model provides a technical solution: a protective shell for an anti-collision laser radar, including a support leg 1. Three brackets 11 are equidistantly fixed to the outer wall of the support leg 1. A laser radar body 12 is mounted on the top of the support leg 1. Side plates 13 are fixedly connected to both sides of the laser radar body 12. Two insert plates 14 are symmetrically fixed to the outer wall of the side plates 13. A protective plate 15 is provided on one side of each insert plate 14. A slot 16 is provided inside the protective plate 15, and the insert plate 14 fits into the inner wall of the slot 16. The interior of the protective plate 15 is... The protective plate 15 is equipped with a locking component and has two sets of shock-absorbing components inside. The shock-absorbing components include two damping rods 3, which are symmetrically fixedly installed on the inner wall of the protective plate 15. The outer walls of the two damping rods 3 are slidably connected to sliders 32. One side of each slider 32 is rotatably connected to a connecting shaft 33. The two connecting shafts 33 are pressed against the outer wall of the side plate 13. A second spring 31 is sleeved on the outer wall of the damping rod 3. One end of the second spring 31 is fixedly connected to the slider 32, and the other end of the second spring 31 is fixedly connected to the protective plate 15.

[0027] With the above technical solution, when installing the protective plate 15 on the outside of the lidar body 12, the protective plate 15 is sleeved on the insert plate 14, and the insert plate 14 is inserted into the slot 16. Through the set locking component, the protective plate 15 is installed on the insert plate 14, and the protective plate 15 can slide on the insert plate 14. When the lidar body 12 encounters an external force collision, the protective plate 15 protects against the external force collision. Under the action of the external force collision, the protective plate 15 is pushed to slide on the insert plate 14. Under the pushing action of the connecting shaft 33, the slider 32 slides on the damping rod 3, pressing the second spring 31. When the external force collision disappears, under the action of the second spring 31, the slider 32 slides back on the damping rod 3, so that the protective plate 15 is reset. Thus, through the cooperation of the slider 32, the second spring 31, and the damping rod 3, the protective plate 15 is shock-absorbing, thereby improving the protection effect of the lidar body 12 and preventing the lidar body 12 from being damaged by external force collision.

[0028] Specifically, the outer wall of the protective plate 15 is provided with a rubber pad 17.

[0029] Through the above technical solution, the rubber pad 17 can protect the surface of the protective plate 15 and prevent the surface of the protective plate 15 from being worn by external impact.

[0030] Specifically, the locking assembly includes two locking blocks 2, which are symmetrically arranged inside the protective plate 15 and slidably connected to the protective plate 15. One end of each locking block 2 extends into the interior of two slots 16. The outer wall of the locking block 2 is set as a slope. The outer wall of the insert plate 14 is provided with a slot 24 for use with the locking block 2. An unlocking unit is provided inside the protective plate 15. The unlocking unit includes two sliding shafts 21, which are symmetrically arranged inside the protective plate 15 and slidably connected to the protective plate 15. The two sliding shafts 21 are fixedly connected to the two locking blocks 2 respectively. A sliding plate 23 is fixedly connected to the end of each sliding shaft 21 that is close to each other. The sliding plate 23 is slidably connected to the protective plate 15. A first spring 22 is sleeved on the outer wall of the sliding shaft 21. One end of the first spring 22 is fixedly connected to the locking block 2, and the other end of the first spring 22 is fixedly connected to the protective plate 15.

[0031] With the above technical solution, the protective plate 15 is fitted onto the insert plate 14, and the insert plate 14 is inserted into the slot 16. At this time, the end of the insert plate 14 abuts against the inclined surface of the outer wall of the locking block 2, pushing the locking block 2 to move, driving the sliding shaft 21 to move, and pressing the first spring 22. When the slot 24 moves to the same vertical plane as the locking block 2, under the action of the first spring 22, the locking block 2 is inserted into the slot 24. Through the limiting of the locking block 2, the protective plate 15 is installed on the insert plate 14. When the protective plate 15 is hit by an external force, the protective plate 15 slides on the insert plate 14, and the locking block 2 slides in the slot 24. When it is necessary to maintain the laser radar body 12, the protective plate 15 needs to be disassembled. At this time, the two sliding plates 23 are pinched to bring the two sliding plates 23 closer to each other, driving the two sliding shafts 21 closer to each other, driving the two locking blocks 2 closer to each other. After the two locking blocks 2 come closer to each other, they separate from the two slots 24. After the limiting of the locking blocks 2 is lost, the protective plate 15 can be easily removed.

[0032] Specifically, several top rods 43 are equidistantly slidably connected to the top of each of the two protective plates 15. Dovetail plates 42 are fixedly connected to the top of each of the two sets of top rods 43. Top plates 4 are provided on the outer walls of the two dovetail plates 42. Dovetail grooves 41 that fit with the dovetail plates 42 are opened at the bottom of the top plates 4. The top of the top plates 4 are set as symmetrical inclined surfaces. A third spring 44 is sleeved on the outer wall of the top rods 43. The bottom of the third spring 44 is fixedly connected to the protective plate 15, and the top of the third spring 44 is fixedly connected to the dovetail plates 42.

[0033] With the above technical solution, the top plate 4 is set above the lidar body 12. When installing the two protective plates 15, as the protective plates 15 are inserted into the insert plate 14, the two dovetail plates 42 are respectively inserted into the two dovetail slots 41. Through the limiting of the two dovetail plates 42 and the support of the third spring 44, the top plate 4 is installed above the lidar body 12, and the top plate 4 protects the top of the lidar body 12.

[0034] Specifically, a top block 45 is fixedly connected to the bottom of the top rod 43. The top block 45 is slidably connected to the protective plate 15. An inclined groove 46 is opened inside the protective plate 15, and the top block 45 fits into the top of the inclined groove 46.

[0035] Through the above technical solution, when the top plate 4 encounters an external force collision, it moves downward, causing the top rod 43 to move downward, causing the top block 45 to move downward. The top block 45 presses against the inclined groove 46, pushing the inclined groove 46 closer to the laser radar body 12, thereby causing the protective plate 15 to move closer to the laser radar body 12. Again, through the cooperation of the slider 32, the second spring 31, and the damping rod 3, the top plate 4 is damped to prevent the laser radar body 12 from being damaged by external force collision.

[0036] In use, when installing the protective plate 15 on the outside of the lidar body 12, the protective plate 15 is fitted onto the insert plate 14, and the insert plate 14 is inserted into the slot 16. At this time, the end of the insert plate 14 abuts against the inclined surface of the outer wall of the locking block 2, pushing the locking block 2 to move, driving the sliding shaft 21 to move, and pressing the first spring 22. When the slot 24 moves to the same vertical plane as the locking block 2, under the action of the first spring 22, the locking block 2 is inserted into the slot 24. Through the limiting of the locking block 2, the protective plate 15 is installed on the insert plate 14. When the protective plate 15 is hit by an external force, the protective plate 15 slides on the insert plate 14, and the locking block 2 slides in the slot 24. When the lidar body 12... When encountering an external impact, the protective plate 15 provides protection. Under the impact, the protective plate 15 slides on the insert plate 14. Driven by the connecting shaft 33, the slider 32 slides on the damping rod 3, pressing the second spring 31. After the impact disappears, the second spring 31 causes the slider 32 to slide back on the damping rod 3, resetting the protective plate 15. Thus, through the cooperation of the slider 32, the second spring 31, and the damping rod 3, the protective plate 15 absorbs shock, thereby improving the protection of the lidar body 12 and preventing damage from external impacts. When maintaining the body 12, the protective plate 15 needs to be disassembled. At this time, pinch the two sliding plates 23, bringing them closer together. This causes the two sliding shafts 21 to move closer together, which in turn moves the two locking blocks 2 closer together. After the two locking blocks 2 move closer together, they separate from the two locking slots 24. Without the locking blocks 2's restraint, the protective plate 15 can be easily removed. The rubber pads 17 provide surface protection for the protective plate 15, preventing wear from external impacts. The top plate 4 is placed above the laser radar body 12. When installing the two protective plates 15, as the protective plates 15 are inserted into the insert plate 14, the two dovetail plates 42 are respectively inserted into the two... Within the dovetail groove 41, the top plate 4 is installed above the lidar body 12 by the limiting of two dovetail plates 42 and the support of the third spring 44. The top plate 4 protects the top of the lidar body 12. When the top plate 4 is hit by an external force, it moves downward, driving the top rod 43 to move downward, causing the top block 45 to move downward. The top block 45 presses against the inclined groove 46, pushing the inclined groove 46 closer to the lidar body 12, thereby causing the protective plate 15 to move closer to the lidar body 12. Again, through the cooperation of the slider 32, the second spring 31, and the damping rod 3, the top plate 4 is damped to prevent the lidar body 12 from being damaged by external force.
