Description

Technical Field

[0001] The utility model relates to the technical field of lidar, in particular to a stabilizing mechanism for airborne lidar. Background Art

[0002] A lidar is a radar system that detects the position, speed and other characteristic quantities of a target by emitting laser beams. In terms of working principle, there is no fundamental difference from a microwave radar: a detection signal (laser beam) is emitted to the target, and then the received signal (target echo) reflected from the target is compared with the emitted signal. After appropriate processing, relevant information about the target can be obtained, such as parameters of the target distance, azimuth, altitude, speed, attitude, and even shape, so as to detect, track and identify targets such as airplanes and missiles.

[0003] In the prior art, lidars are generally connected through connecting columns, and there is no device for supporting the radar during rotation, so the stability of the radar during rotation cannot be guaranteed. Moreover, the installation of the radar in the prior art is relatively complex, and multiple operations are required to fix the radar, and the force application points at multiple angles of the radar cannot be guaranteed to be the same, so the stability of the radar installation cannot be guaranteed.

[0021] Referring to Figures 1-3 , the stabilizing mechanism of the airborne lidar includes a mounting plate 1. A plurality of symmetrically arranged mounting holes 2 are provided at the upper end of the mounting plate 1. A base 17 is provided at the upper end of the mounting plate 1. A connecting column 10 is provided at the upper end of the base 17. A radar body 5 is provided at the upper end of the connecting column 10. A rotating groove 3 is provided at the upper end of the mounting plate 1. A plurality of circumferentially arranged moving grooves 6 are provided at the upper end of the base 17. A fixing mechanism for fixing the base 17 is provided in each of the plurality of moving grooves 6. The fixing mechanism includes a threaded rod 7 rotatably connected through the moving groove 6 and the rotating groove 3. A moving block 8 is threadedly connected to the outer wall of each of the plurality of threaded rods 7. A plug board 9 is provided on the side wall of the moving block 8. A plurality of circumferentially arranged slots 18 are provided on the outer wall of the base 17 and are matched with the plurality of plug boards 9. By driving the plurality of plug boards 9 to move through the plurality of moving blocks 8, the plurality of plug boards 9 are inserted into the plurality of slots 18, so as to realize the rapid installation of the radar body 5. At the same time, through the multi-directional fixation of the base 17, the stability of the installation of the radar body 5 is fully ensured.

[0022] A supporting mechanism for supporting the radar body 5 is provided on the outer wall of the connecting column 10. The supporting mechanism includes a connecting ring 12 arranged outside the connecting column 10. The connecting ring 12 and the connecting column 10 are rotatably connected through a bearing 11. The outer wall of the connecting ring 12 is connected to the lower end of the radar body 5 through a connecting plate 13. The connecting plate 13 is inclined. By utilizing the function of the bearing 11 between the connecting ring 12 and the connecting column 10 and the connecting function of the connecting plate 13, the connecting plate 13 rotates with the rotation of the radar body 5, so that the connecting plate 13 always supports the radar body 5, thus fully ensuring the stability of the radar body 5 during operation.

[0023] A rotating ring 15 is rotatably connected in the rotating groove 3. A damping gasket is provided at the rotating connection of the rotating ring 15 and the rotating groove 3. A bevel gear ring 16 is provided at the upper end of the rotating ring 15. A bevel gear 19 meshing with the bevel gear ring 16 is provided at the end of each of the plurality of threaded rods 7.

[0025] The number of the multiple threaded rods 7 is four, and the multiple threaded rods 7 are circumferentially arranged.

[0026] When the utility model is in use, during the rotation operation of the radar body 5, the radar body 5 rotates on the upper end of the connecting column 10. Under the action of the bearing 11 between the connecting ring 12 and the connecting column 10 and the connecting action of the connecting plate 13, the connecting plate 13 rotates following the rotation of the radar body 5, so that the connecting plate 13 always supports the radar body 5, thus fully ensuring the stability of the radar body 5 during operation.

[0027] When installing the radar body 5, rotate the operation ring 4. Under the connecting action of the multiple fixing rods 14, the operation ring 4 drives the rotating ring 15 to rotate (the damping gasket restricts the position of the rotating ring 15 after rotation), so that the bevel gear ring 16 at the upper end of the rotating ring 15 rotates. By using the meshing of the bevel gear ring 16 and the multiple bevel gears 19, the multiple bevel gears 19 rotate to drive the multiple threaded rods 7 to rotate. By using the threaded connection between the threaded rods 7 and the moving blocks 8, the multiple moving blocks 8 drive the multiple inserting plates 9 to move, and the multiple inserting plates 9 are inserted into the multiple slots 18, so as to realize the rapid installation of the radar body 5.
