[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1-4In this embodiment of the utility model, a drone suspension structure includes a drone body 1. A downwardly extending mounting member 2 is fixedly installed on the bottom plate of the drone body 1. Two mounting members 2 aligned in the longitudinal direction are fixedly connected to the same fixed rod 3. Support rods 4 are fixedly installed at both ends of the outer walls of the two fixed rods 3. A mounting plate 5 is fixedly installed at the top of the support rod 4. A winding mechanism is installed at the top of the mounting plate 5. The winding mechanism is used to wind and unwind the connecting rope 11. A sliding protective mechanism for protecting the connecting rope 11 is installed at the bottom of the mounting plate 5.
[0015] In this embodiment: when the drone descends to a certain altitude, the winding mechanism unwinds the connecting rope 11. The unwound connecting rope 11 moves downward, allowing it to be connected to the transported object without the drone needing to land completely. Similarly, when the transported item reaches its destination, it does not need to land completely or come into contact with the ground. The unwinding of the connecting rope 11 causes the transported item to descend slowly, thus achieving the purpose of convenient use.
[0016] Please refer to this carefully. Figure 3 The winding mechanism includes a winding reel 6 mounted on the top of the mounting plate 5 via a bracket. Two winding reels 6 with their end faces aligned are coaxially connected via a synchronous shaft 7. Synchronous pulleys 8 are interference-fitted onto the outer periphery of the two synchronous shafts 7. The two synchronous pulleys 8 are connected by a synchronous belt 9. A forward and reverse rotating shaft motor 10 is mounted on the outside of any bracket. The forward and reverse rotating shaft motor 10 is coaxially connected to one winding reel 6. The winding reel 6 is used to wind or unwind the connecting rope 11. The mounting plate 5 has a slot 13 aligned with the winding mechanism inside. One end of the connecting rope 11 passes through the slot 13 to the bottom of the mounting plate 5. A lifting ring 12 is fixedly installed at the bottom end of the connecting rope 11.
[0017] In this embodiment: by starting the forward and reverse rotating shaft motor 10, the forward and reverse rotating shaft motor 10 drives the winding 6 connected to it to rotate. The rotating winding 6 drives another winding 6 coaxially connected to it to rotate synchronously and in the same direction through the synchronous shaft 7. At the same time, the rotating synchronous shaft 7 drives the synchronous wheel 8 installed on the outer periphery to rotate. The synchronous wheel 8 drives another synchronous wheel 8 to rotate through the synchronous belt 9. The other synchronous wheel 8 drives two other winding 6 to rotate through the synchronous shaft 7, so as to realize the synchronous and unidirectional rotation of the four winding 6, thereby achieving the purpose of winding and unwinding the connecting rope 11. When the connecting rope 11 is unwound, one end of the connecting rope 11 moves down and can be hooked to the hook on the suspended object through the lifting ring 12. When the connecting rope 11 is wound up, the connecting rope 11 can be wound up to facilitate the flight of the drone body 1 when it is unloaded.
[0018] Please refer to this carefully. Figure 3 The sliding protection mechanism includes slide rails 14 fixedly installed at the bottom of the mounting plate 5 and located on both sides of the slot 13. Sliding grooves are opened on the inner side of the two slide rails 14. Sliding sliders 15 extending to the outside of the slide rails 14 are slidably installed on the inner wall of the sliding grooves. Protective sleeves 16 are welded to the inner walls of the two sliders 15. The top of the protective sleeves 16 extends upward and is slidably connected to the inner wall of the slot 13. The protective sleeves 16 have a hollow structure, and the connecting rope 11 passes through the inner cavity of the protective sleeves 16.
[0019] In this embodiment: during the winding and unwinding process of the connecting rope 11, the connecting rope 11 wound around the outer periphery of the winding reel 6 is in a circular state. The diameter of this circular state changes continuously during winding and unwinding. At this time, the protective sleeve 16 slides axially along with the winding or unwinding connecting rope 11. The protective sleeve 16 drives the slider 15 to slide within the slide rail 14. This design can prevent the connecting rope 11 from rubbing against the groove 13, thus avoiding the connecting rope 11 being cut by the groove 13.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
