[0016] This utility model proposes an installation structure for a rotating lidar pod for unmanned aerial vehicles (UAVs). Compared with the prior art, the advantages of this utility model are:

[0017] 1. The mounting structure of the UAV rotating lidar pod is equipped with a first gear plate and a second gear plate. By rotating the first hand handle by external force, the first gear plate can be rotated. Through the meshing structure of the first gear plate and the rack plate, the rotation of the first gear plate can cause the rack plate to rotate. Similarly, the rotation of the rack plate can cause multiple sets of second gear plates to rotate, indirectly driving the hollow column to rotate. Then, through the threaded connection between the first threaded groove and the first threaded column, the rotation of the hollow column can cause the first threaded column to rise and fall, thereby driving the lifting plate to rise and fall. The rise of the lifting plate can lock and fix the top of the mounting frame to the inner side of the hollow cylindrical frame, allowing for indirect and quick assembly and disassembly of the lidar pod. This avoids the problem that most of the lidar pod's mounting structure is fixed by threaded nails, which makes the lidar pod's mounting structure inconvenient for assembly and disassembly.

[0018] 2. The mounting structure of the UAV rotating lidar pod is equipped with a first bevel gear and a second bevel gear. By rotating the second hand crank with external force, the first bevel gear can be driven to rotate. Through the meshing structure of the first and second bevel gears, the rotation of the first bevel gear can cause the second bevel gear to rotate, which indirectly drives the second threaded column to rotate. Then, through the threaded connection between the second threaded column and the second threaded groove, the rotation of the second threaded column can move the moving frame. The movement of the moving frame can move the clamping frame. The relative movement of the two sets of clamping frames can form a clamping assembly, which facilitates the quick installation and removal of the mounting structure from the UAV, increasing the practicality of the device.

[0029] Furthermore, the first hand crank 4 forms a rotating structure with the fixed plate 2 via the first bearing 3, and the first hand crank 4 forms a fixed structure with the first gear plate 5. The first gear plate 5 forms a meshing structure with the rack plate 6, and the rack plate 6 forms a fixed structure with the fixed column 8 via the second bearing 7. By rotating the first hand crank 4 with external force, the first gear plate 5 can be driven to rotate. Through the meshing structure of the first gear plate 5 and the rack plate 6, the rotation of the first gear plate 5 can cause the rack plate 6 to rotate. Similarly, the rotation of the rack plate 6 can cause multiple sets of second gear plates 9 to rotate, indirectly driving the hollow column 10 to rotate.

[0030] Furthermore, the rack plate 6 and the second gear plate 9 form a meshing structure, and the second gear plate 9 and the hollow column 10 form a fixed structure. The hollow column 10 is connected to the first threaded column 13 through the first threaded groove 12. The baffle 14 is connected to the lifting plate 15 through the first threaded column 13.

The rise of the lifting plate 15 can lock and fix the top of the mounting frame 17 to the inside of the hollow cylindrical frame 1, allowing for indirect and rapid assembly and disassembly of the laser radar pod.

[0031] Furthermore, the connecting column 21 forms a rotating structure with the hollow plate 19 via the fourth bearing 20, and the second hand crank 22 forms a fixed structure with the first bevel gear 23 via the connecting column 21. The first bevel gear 23 and the second bevel gear 24 form a meshing structure, and the second bevel gear 24 and the second threaded column 25 form a fixed structure. By rotating the second hand crank 22 with external force, the first bevel gear 23 can be driven to rotate. Through the meshing structure of the first bevel gear 23 and the second bevel gear 24, the rotation of the first bevel gear 23 can cause the second bevel gear 24 to rotate, indirectly driving the second threaded column 25 to rotate.

[0032] Furthermore, the second threaded post 25 forms a rotating structure with the hollow plate 19 through the fifth bearing 26, and the second threaded post 25 forms a threaded connection with the movable frame 28 through the second threaded groove 27; through the threaded connection of the second threaded post 25 and the second threaded groove 27, the rotation of the second threaded post 25 can move the movable frame 28, and the movement of the movable frame 28 can move the clamping frame 29. The relative movement of the two sets of clamping frames 29 can form a clamping assembly, which facilitates the quick installation and removal of the mounting structure onto the drone.

[0033] Furthermore, the movable frame 28 forms a sliding structure with the slider 30 and the slide rail 31, and the movable frame 28 forms a fixed structure with the clamping frame 29. Through the threaded connection of the second threaded post 25 and the second threaded groove 27, the rotation of the second threaded post 25 can move the movable frame 28, and the movement of the movable frame 28 can move the clamping frame 29. The relative movement of the two sets of clamping frames 29 can form a clamping assembly, which facilitates the quick installation and removal of the mounting structure from the drone.

[0034] Working principle: First, the operator needs to rotate the second hand crank 22 by external force, which drives the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 causes the second bevel gear 24 to rotate, which indirectly drives the second threaded column 25 to rotate. The rotation of the second threaded column 25 causes the moving frame 28 to move, and the movement of the moving frame 28 causes the clamping frame 29 to move. The relative movement of the two sets of clamping frames 29 can form a clamping assembly, which facilitates the quick installation of the mounting structure onto the drone. Then, by rotating the first hand crank 22 by external force... The handle 4 can drive the first gear plate 5 to rotate. Through the meshing structure of the first gear plate 5 and the rack plate 6, the rotation of the first gear plate 5 can cause the rack plate 6 to rotate. Similarly, the rotation of the rack plate 6 can cause multiple sets of second gear plates 9 to rotate, indirectly driving the hollow column 10 to rotate. The rotation of the hollow column 10 can cause the first threaded column 13 to rise and fall, thereby driving the lifting plate 15 to rise and fall. The rise of the lifting plate 15 can lock and fix the top of the mounting frame 17 to the inside of the hollow cylindrical frame 1, allowing for the indirect and rapid assembly and disassembly of the laser radar pod.
