DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: an adjustment structure for a lidar, including a hollow base 1, an adjustment component 2 and a disassembly and assembly component 3. The adjustment component 2 is arranged on the top of the hollow base 1. The adjustment component 2 includes a second rotating rod 204, a secondary bevel gear 205 and a mounting block 206. The inner bottom of the hollow base 1 is rotatably connected to one end of the second rotating rod 204. The outer wall of the second rotating rod 204 is fixedly connected to the inside of the secondary bevel gear 205. The other end of the second rotating rod 204 extends above the hollow base 1 and is fixedly connected to the bottom of the mounting block 206. The disassembly and assembly component 3 is arranged above the hollow base 1. The disassembly and assembly component 3 includes a circular block 301, a limiting hole 302, a connecting cylinder 303 and a movable rod 304. The inside of the mounting block 206 is provided with a circular block 301. The outer wall of the circular block 301 is provided with a limiting hole 302. The outer wall of the mounting block 206 is fixedly installed with a connecting cylinder 303. The front side of the connecting cylinder 303 is slidably installed with a movable rod 304. One end of the movable rod 304 passes through the mounting block 206 and extends into the limiting hole 302. The other end of the movable rod 304 is fixedly installed with an auxiliary pull ring 7. The top of the circular block 301 is fixedly installed with a lidar body 4. The bottom of the mounting block 206 is fixedly installed with a washer 5. The washer 5 is in contact with but not connected to the top of the hollow base 1. The outer wall of the hollow base 1 is fixedly installed with multiple positioning pieces 6.

[0025] Secondly, the adjustment component 2 further includes a reduction motor 201, a first rotating rod 202 and a main bevel gear 203. A reduction motor 201 is fixedly installed on one side of the hollow base 1. One side inner wall of the hollow base 1 is rotatably connected to one end of the first rotating rod 202. The output shaft of the reduction motor 201 is fixedly connected to one end of the first rotating rod 202. The outer wall of the first rotating rod 202 is fixedly connected to the inside of the main bevel gear 203. The main bevel gear 203 meshes with the secondary bevel gear 205. The size of the secondary bevel gear 205 is larger than that of the second rotating rod 204, which is convenient for arbitrarily adjusting the orientation angle of the lidar body 4 with higher adjustment accuracy, enabling it to adapt to the changing use scenarios, avoiding monitoring blind spots, increasing the available range of the device, and improving the flexibility and practicality of the device.

[0026] Furthermore, the disassembly and assembly component 3 further includes that the outer wall of the movable rod 304 is fixedly connected to the inside of a partition piece 305. The rear side of the partition piece 305 is fixedly connected to one end of a spring 306. The other end of the spring 306 is fixedly connected to the front side inner wall of the connecting cylinder 303. The movable rod 304 passes through the inside of the spring 306, which can quickly disassemble and install the lidar body 4, facilitating the maintenance and replacement of the damaged lidar body 4 by the staff. The operation is simple and easy to master, reducing the workload of the staff.

[0027] A lidar includes the above-mentioned adjustment structure for a lidar.

[0028] Working principle: When in use, the hollow base 1 is fixed on the machine body through the positioning piece 6. When it is necessary to adjust the angle of the lidar body 4, the deceleration motor 201 is turned on to drive the first rotating rod 202 to rotate, driving the main bevel gear 203 to rotate. Since the size of the secondary bevel gear 205 is larger than that of the main bevel gear 203, under the meshing drive of the main bevel gear 203 on the secondary bevel gear 205, the second rotating rod 204 rotates at a further reduced speed, thereby driving the mounting block 206 to rotate and precisely adjusting the orientation angle of the lidar body 4. When a fault occurs in the lidar body 4, the auxiliary pull ring 7 is pulled outwards to drive the movable rod 304, driving the partition piece 305 to move in the connecting cylinder 303 and compress the spring 306, so that one end of the movable rod 304 is removed from the limiting hole 302, canceling the limitation on the circular block 301, and the circular block 301 is taken out from the mounting block 206, then the lidar body 4 can be removed. The installation is the same in principle.

[0029] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present utility model.
