[0001] This utility model relates to the field of mechanical structure design technology, and in particular to a quick-locking structure for folding drone wings. Background Technology

[0002] In ships, vehicles, or small hangars, drones need to be stored compactly. Folding wings can reduce storage space requirements by more than 50%. For example, a certain type of shipborne drone has increased storage density by 3 times through a folding design. In batch transportation scenarios, the folding structure can significantly improve transportation efficiency, such as increasing the single transportation volume by 200% and reducing logistics costs. Therefore, a folding drone wing quick-locking structure is needed.

[0003] The foldable drone wing quick-locking structure is a mechanical device used to enable the rapid folding of drone wings and to securely lock them after folding. In previous technologies, drones that could not be folded would occupy more space during storage or transportation, reducing space utilization, which is particularly disadvantageous for scenarios that require efficient use of limited space. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-locking structure for foldable drone wings, which aims to improve the problem that drones that cannot be folded will occupy more space and reduce space utilization during storage or transportation.

[0009] Preferably, the outer wall of the limiting block is slidably connected to the interior of the wing body, and a rotating plate is rotatably connected to the outer wall of the limiting block.

[0010] Preferably, a connecting rod is fixedly connected inside the rotating plate, and a connecting plate is rotatably connected to the outer wall of the connecting rod.

[0011] Preferably, the connecting piece is rotatably connected to the outer wall of the connecting block, and the rotating piece is rotatably connected to a fixed rod.

[0012] Preferably, a fixing column is fixedly connected to the outer wall of the fixing rod, and the outer wall of the fixing column is fixedly connected to the outer wall of the fixing block.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a foldable UAV wing quick-locking structure, including a rotating block 1. A first hydraulic cylinder 2 is fixedly connected to the outer wall of the rotating block 1. A push rod 3 is fixedly connected to the output end of the first hydraulic cylinder 2. A first arc-shaped piece 4 is rotatably connected to the outer wall of the push rod 3. A moving block 5 is rotatably connected to the inside of the first arc-shaped piece 4. A wing body 6 is fixedly connected to the outer wall of the moving block 5. A fixing plate 7 is rotatably connected to the outer wall of the wing body 6. A second arc-shaped piece 9 is rotatably connected to the outer wall of the fixing plate 7. The inside of the second arc-shaped piece 9 is rotatably connected to the outer wall of the push rod 3. An organism 8 is fixedly connected to the outer wall of the organism 8. A limit assembly is provided on the outer wall of the organism 8. The limit assembly includes a fixing piece 10. The outer wall of the fixing piece 10 is fixedly connected to the outer wall of the organism 8. A limit rod 11 is fixedly connected to the inside of the fixing piece 10. The inside of the rotating block 1 is rotatably connected to the outer wall of the limit rod 11.

[0024] Specifically, the body 8 provides fixed support for the fixed plate 10, which in turn provides fixed support for the limiting rod 11. Simultaneously, the limiting rod 11 limits the rotation block 1. The rotation block 1 connects the limiting rod 11 and the first hydraulic cylinder 2, thus limiting the first hydraulic cylinder 2. The first hydraulic cylinder 2 drives the push rod 3, which in turn rotates the first arc-shaped piece 4 on the outer wall of the moving block 5. The moving block 5 limits the first arc-shaped piece 4. The moving block 5 then rotates the wing body 6 inside the fixed plate 7. The body 8 provides fixed support for the fixed plate 7, which in turn limits the wing body 6. The push rod 3 drives the second arc-shaped piece 9 to rotate on the outer wall of the fixed plate 7, which limits the second arc-shaped piece 9, and thus limits the push rod 3. This significantly reduces the size and space occupied by the UAV in non-flying mode, making it easier to carry and transport.

[0025] Reference Figure 1 and Figure 4 A fixing block 12 is fixedly connected to the outer wall of the fuselage 8. A second hydraulic cylinder 13 is fixedly connected inside the fixing block 12. A connecting block 14 is fixedly connected to the output end of the second hydraulic cylinder 13. A movable piece 15 is rotatably connected to the outer wall of the connecting block 14. A limit block 16 is rotatably connected inside the movable piece 15. The outer wall of the limit block 16 is slidably connected to the inside of the wing body 6. A rotating piece 17 is rotatably connected to the outer wall of the limit block 16.

[0026] Specifically, the body 8 provides fixed support for the fixed block 12, the fixed block 12 provides fixed support for the second hydraulic cylinder 13, the second hydraulic cylinder 13 drives the connecting block 14, which in turn drives the moving piece 15 to move, and the moving piece 15 drives the limiting block 16 to slide inside the wing body 6, thereby limiting the wing body 6 and preventing the wing from deploying due to accidental contact during transportation, storage or maintenance.

[0027] Reference Figure 4 A connecting rod 18 is fixedly connected inside the rotating plate 17, and a connecting plate 19 is rotatably connected to the outer wall of the connecting rod 18; the inner part of the connecting plate 19 is rotatably connected to the outer wall of the connecting block 14, and a fixing rod 20 is rotatably connected inside the rotating plate 17; a fixing column 21 is fixedly connected to the outer wall of the fixing rod 20, and the outer wall of the fixing column 21 is fixedly connected to the outer wall of the fixing block 12.

[0028] Specifically, the limiting block 16 drives the rotating piece 17, which in turn drives the connecting rod 18 to move. The connecting rod 18 drives the connecting piece 19 to rotate on the outer wall of the connecting block 14. The connecting block 14 limits the connecting piece 19, which in turn limits the connecting rod 18. The rotating piece 17 rotates on the outer wall of the fixed rod 20, which in turn assists in limiting the limiting block 16. The fixed block 12 provides fixed support for the fixed column 21, which in turn provides fixed support for the fixed rod 20.

[0029] Working principle: When this structure is needed, the first hydraulic cylinder 2 on the outer wall of the rotating block 1 is activated. The first hydraulic cylinder 2 drives the push rod 3, which in turn drives the first arc-shaped piece 4 to rotate on the outer wall of the moving block 5. The moving block 5 drives the wing body 6 to rotate inside the fixed plate 7. At the same time, the push rod 3 drives the second arc-shaped piece 9 to rotate on the outer wall of the fixed plate 7. This allows the UAV to significantly reduce its size and space occupation when not in flight, making it easier to carry and transport.

[0030] The second hydraulic cylinder 13 inside the fixed block 12 is activated, which drives the connecting block 14 and then the moving piece 15 to move. The moving piece 15 drives the limiting block 16 to slide inside the wing body 6, preventing the wing from deploying due to accidental contact during transportation, storage, or maintenance. At the same time, the limiting block 16 drives the rotating piece 17 and then the connecting rod 18 to move. The connecting rod 18 drives the connecting piece 19 to rotate on the outer wall of the connecting block 14. Meanwhile, the rotating piece 17 rotates on the outer wall of the fixed rod 20, thus providing auxiliary limiting for the limiting block 16. This structure not only significantly reduces the size and space occupied by the UAV in non-flying state, making it easier to carry and transport, but also prevents the wing from deploying due to accidental contact during transportation, storage, or maintenance.
