[0002] A multi-rotor drone is a special type of unmanned helicopter with three or more rotor shafts. It generates lift and thrust by rotating rotors via electric motors on each shaft. Unlike conventional helicopters, the collective pitch of the rotors is fixed. By changing the relative speeds between the different rotors, the magnitude of the thrust per shaft can be altered, thereby controlling the aircraft's trajectory.
[0003] Multi-rotor drone hoisting refers to the technology of using a multi-rotor drone equipped with a hoisting system to safely and efficiently move heavy objects from one location to another through precise flight control and sling operation. This technology integrates high-precision positioning, cutting-edge sensors, a powerful power system, and intelligent control algorithms to ensure the stability and accuracy of hoisting operations.
[0004] Existing hoisting mechanisms have the following drawbacks in actual use:
[0005] Most existing hoisting mechanisms use ropes and hooks to lift objects. However, since the ropes are soft, the objects tend to swing in the air after being lifted, which can easily cause them to fall and create danger. Utility Model Content

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.
[0025] To address the problems existing in the background technology, this application proposes the following technical solution: an anti-sway stabilizing structure for hoisting multi-rotor UAVs.
[0026] The specific technical solution includes a drone body 1 and a hoisting mechanism 3. A stabilizing mechanism 10 is provided on the lower side of the hoisting mechanism 3. The stabilizing mechanism 10 includes a fixed frame 11, a telescopic mechanism 12, and a stabilizing plate 16. The fixed frame 11 is located on the lower side of the hoisting mechanism 3, and the telescopic mechanism 12 is located on the lower side of the fixed frame 11. Multi-stage electric telescopic rods 13 are provided on both sides of the telescopic mechanism 12. A snap-fit plate 14 is fixedly installed at the output end of the multi-stage electric telescopic rod 13. The stabilizing plate 16 is located at the output end of the hoisting mechanism 3. A snap-fit post 17 is fixedly installed on the upper side of the stabilizing plate 16. Snap-fit grooves 18 are provided on the periphery of the snap-fit post 17 and on one side of the two snap-fit plates 14. The snap-fit plates 14 and the snap-fit posts 17 are snapped together through the snap-fit grooves 18. The telescopic mechanism 12 includes a fixed shell 19, a rotating shaft 21, a gear 22, and a toothed plate 23. There are two toothed plates 23. The fixed shell 19 is fixedly installed on the lower side of the fixed frame 11. A stabilizing plate 19 is provided inside the fixed shell 19. The device has a sliding cavity 20, a rotating shaft 21 rotatably mounted inside the sliding cavity 20, a gear 22 fixedly mounted around the rotating shaft 21, a toothed plate 23 slidably mounted inside the sliding cavity 20 and meshing with the gear 22, and a fixed sleeve 24 fixedly mounted at one end of each of the two toothed plates 23. The two fixed sleeves 24 are located at both ends of the fixed housing 19. A multi-stage electric telescopic rod 13 is fixedly mounted inside the fixed sleeve 24. A turbine 25 is fixedly mounted around the rotating shaft 21. A groove is opened on one side of the inner wall of the sliding cavity 20, and a rotating motor 27 is fixedly mounted in the groove. A worm gear 26 is fixedly mounted at the output end of the rotating motor 27 and meshes with the turbine 25. Through the self-locking of the worm gear 26 and the turbine 25, the rotating shaft 21 can be locked, thereby preventing the gear from rotating and ensuring the stability of the snap-fit plate 14 during use. There are through grooves in the middle of both the fixed housing 19 and the rotating shaft 21 to facilitate the passage of the lifting rope 6.
[0027] Reference Figure 2 and Figure 3 As shown, the hoisting mechanism 3 includes a mounting frame 4, a take-up roller 5, a hoisting rope 6, and a hook 15. The mounting frame 4 is fixedly installed on the lower side of the UAV body 1. The take-up roller 5 is rotatably installed between the mounting frames 4. The hoisting rope 6 is wound around the take-up roller 5. The stabilizing plate 16 is fixedly installed at one end of the hoisting rope 6. The hook 15 is located on the lower side of the stabilizing plate 16. A drive motor 9 is fixedly installed on one side of the inner wall of the mounting frame 4. The output end of the drive motor 9 is fixedly connected to one end of the take-up roller 5. Two support legs 2 are fixedly installed on the lower side of the UAV body 1. The mounting frame 4 is located between the two support legs 2. By starting the drive motor 9, the take-up roller 5 is driven to rotate. The rotation of the take-up roller 5 can wind and unwind the hoisting rope 6, thereby facilitating the adjustment of the length of the hoisting rope 6. The height of the multi-stage electric telescopic rod 13 after being retrieved is less than the height of the support legs 2, thereby avoiding any impact on the landing of the UAV body 1.
[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0029] In use, after the hook 15 lifts an item, the multi-stage electric telescopic rod 13 is activated, causing the locking plate 14 to move to correspond with the locking post 17. Then, the rotary motor 27 is activated, causing the worm gear 26 to rotate. The rotation of the worm gear 26 drives the worm wheel 25 to rotate, which in turn drives the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 drives the gear 22 to rotate, which in turn drives the two toothed plates 23 to move synchronously. The synchronous movement of the two toothed plates 23 drives the two gears to move synchronously. The synchronous movement of two fixed sleeves 24 can drive the synchronous movement of two multi-stage electric telescopic rods 13. The synchronous movement of the two multi-stage electric telescopic rods 13 can drive the two locking plates 14 to move toward the locking post 17. The locking plates 14 and the locking post 17 can lock each other to limit the stabilizing plate 16, so that after the hook 15 lifts the item, the item will not swing during transportation, so that the item can be lifted stably, thereby avoiding the danger of the item swinging in the air and falling during lifting.
