[0033] 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.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a collision-resistant unmanned aerial vehicle (UAV), comprising a UAV shell 1, a flight mechanism 4 including a motor and flight blades, enabling the UAV to fly at high altitudes, and a collision-resistant mechanism 2 including a rotating block 21 rotatably connected to the surface of the UAV shell 1. The UAV shell 1 supports and fixes the rotating block 21. A threaded groove is formed on the surface of the UAV shell 1, and a fixing bolt 22 is threaded into this groove. The rotating block 21 is also threaded with the fixing bolt 22. The threaded groove of the UAV shell 1 serves to limit and guide the fixing bolt 22, and the threaded connection between the fixing bolt 22 and the threaded groove of the UAV shell 1 fixes the rotating block 21, preventing further rotation. A connecting shaft 23 passes through and is connected to the surface of the UAV shell 1. The drone shell 1 supports and fixes the connecting shaft 23. The sliding frame 26 is slidably connected in the sliding groove of the drone shell 1. The sliding groove of the drone shell 1 limits and guides the sliding frame 26, so that the sliding frame 26 can only slide along the sliding groove of the drone shell 1. The connecting shaft 23 is fixedly connected to the central axis of the rotating block 21. The rotation of the rotating block 21 will synchronously drive the connecting shaft 23 fixedly connected to the surface to rotate. The surface of the connecting shaft 23 is hinged with a hinge rod 24. The rotation of the connecting shaft 23 will drive the four sets of hinge rods 24 to move closer together or away from each other. The end of the hinge rod 24 away from the connecting shaft 23 is hinged with a quick release mechanism 25. The hinge rod 24 synchronously drives the quick release mechanism 25 to move closer together or away from each other. When not in use, the entire anti-collision mechanism 2 and quick release mechanism 25 can be retracted into the inner wall of the drone shell 1 to reduce storage space. The quick release mechanism 25 includes a locking block 252, which contacts the sliding frame 26.

[0035] Reference Figure 3 - Figure 5The quick-release mechanisms 25 move closer together or further apart, synchronously moving the sliding frame 26. The sliding frame 26 is elastically connected to a sliding block 28 via a spring b27. One end of the spring b27 is fixedly connected to the outer sidewall of the sliding block 28, and the other end is fixedly connected to the inner sidewall of the sliding frame 26. The function of the spring b27 is to elastically reset the sliding block 28. During the drone's flight, if the sliding block 28 collides with an external object, the spring b27 can provide elastic cushioning. The sliding block 28 is made of soft silicone, providing impact protection. A sliding groove is provided on the inner wall of the sliding frame 26, and the sliding block 28 is slidably connected within this groove. The sliding groove of the moving frame 26 serves to limit and guide the sliding block 28, ensuring that the sliding block 28 can only slide along the direction of the sliding frame 26. A rotating shaft 213 is fixedly connected to the surface of the sliding frame 26. The rotating shaft 213 is elastically connected to the sliding seat 29 via a spiral spring 214. One end of the spiral spring 214 is fixedly connected to the outer sidewall of the rotating shaft 213, and the other end is fixedly connected to the inner sidewall of the sliding seat 29. The spiral spring 214 serves to elastically reset the sliding seat 29 after rotation. The sliding seat 29 is rotatably connected to the outer sidewall of the sliding frame 26. During the retraction of the entire anti-collision mechanism 2, no further action is required. When manually retracted, the sidewall of the sliding groove of the drone shell 1 presses against the outer wall of the sliding seat 29, causing it to retract into the empty slot of the sliding frame 26. The sliding seat 29 is rotatably connected to the outer sidewall of the rotating shaft 213. The rotating shaft 213 acts as a limiting guide for the sliding seat 29, ensuring that the sliding seat 29 can only rotate along the direction of the rotating shaft 213. A sliding rod 210 is slidably connected to the inner wall of the sliding seat 29. The sliding rod 210 is elastically connected to a wedge 212 via a spring c211. One end of the spring c211 is fixedly connected to the outer sidewall of the wedge 212, and the other end of the spring c211 is fixedly connected to the inner sidewall of the sliding rod 210. The function of 1 is to elastically reset the moved wedge 212, so that it re-contacts the slot of the sliding seat 29 to complete the fixation. The inner side wall of the sliding rod 210 has a sliding groove, and the wedge 212 is slidably connected in the sliding groove of the sliding rod 210. The function of the sliding groove of the sliding rod 210 is to limit and guide the wedge 212, so that the wedge 212 can only slide along the sliding groove of the sliding rod 210. The surface of the sliding seat 29 has a slot, and the wedge 212 contacts the slot on the surface of the sliding seat 29. By engaging with the slot of the sliding seat 29, the sliding rod 210 can be fixed, so that it can no longer slide in the sliding groove of the sliding seat 29.

[0036] Reference Figure 1 , Figure 2 and Figure 6The quick-release mechanism 25 includes a connecting block 251. The outer sidewall of the connecting block 251 is hinged to the hinge rod 24. There are four sets of connecting blocks 251. Rotation of the hinge rod 24 will cause the four sets of connecting blocks 251 to move closer together or further apart. The inner sidewall of the drone shell 1 has a sliding groove. The connecting block 251 is slidably connected to the inner sidewall of the drone shell 1. The sliding groove of the drone shell 1 serves to limit and guide the connecting block 251, so that the connecting block 251 can only slide along the connecting groove of the drone shell 1. The inner wall of the connecting block 251 has a sliding groove. A locking block 252 is slidably connected to the inner wall of the connecting block 251. The sliding groove of the connecting block 251 serves to limit and guide the locking block 252, so that the locking block 252 can only slide along the connecting block 251. The sliding groove of 1 slides. There are two sets of locking blocks 252. The two sets of locking blocks 252 are elastically connected by spring a253. Pressing the two sets of locking blocks 252 will squeeze the spring a253 on the inner wall. One end of the spring a253 is fixedly connected to the outer side wall of the locking block 252, and the other end of the spring a253 is fixedly connected to the outer side wall of the other set of locking blocks 252. The function of the spring a253 is to automatically reset the two sets of locking blocks 252 after pressing, so that the locking blocks 252 can re-engage with the slot of the sliding frame 26 to complete the fixation. The surface of the sliding frame 26 has a slot, and the slot of the sliding frame 26 has a slot. The locking block 252 contacts the slot of the sliding frame 26. By engaging the locking block 252 with the slot on the inner wall of the sliding frame 26, the sliding frame 26 can be limited and fixed.

[0037] Working principle: During flight, the flight mechanism 4 drives the flight fan blades through the motor to provide lift for the UAV to achieve high-altitude flight. The anti-collision mechanism 2 and the quick-release mechanism 25 work together. Before flight, first, the fixing bolt 22 is rotated to remove the limit on the rotating block 21. Rotating the rotating block 21, the hinge rod 24 pushes the connecting block 251 and the sliding frame 26 outward. The spiral spring 214 drives the sliding seat 29 to reset and open. Then, the wedge block 212 is pressed, so that the wedge block 212 removes the limit on the sliding rod 210. Pulling the sliding rod 210 outward can increase the area. After unfolding, tightening the fixing bolt 22 can fix the rotating block 21. To retract it, rotate the fixing bolt 22 in the opposite direction, and then rotate the rotating block 21 in the opposite direction. This drives the connecting shaft 23 to rotate, so that the four sets of hinge rods 24 hinged on the surface of the connecting shaft 23 move towards each other. The hinge rods 24 pull the connecting block 25 of the quick-release mechanism 25. 51 moves synchronously along the inner sliding groove of the drone shell 1. The connecting block 251 drives the sliding frame 26 to retract towards the inner side of the drone shell 1 through the locking block 252. During the retraction process, the side wall of the sliding groove of the drone shell 1 presses the sliding seat 29, causing it to rotate around the rotating shaft 213 and retract into the empty groove of the sliding frame 26. Finally, the entire anti-collision mechanism 2 and quick-release mechanism 25 are retracted to the inner wall of the drone shell 1, reducing the storage space. When the sliding block 28 hits a foreign object during drone flight, the soft silicone material of the sliding block 28 first buffers the impact force. At the same time, the sliding block 28 slides along the sliding groove of the sliding frame 26 and presses the spring b27. The spring b27 further elastically buffers to weaken the impact force. At the same time, the sliding rod 210 may slide along the inner wall of the sliding seat 29, driving the wedge block 212 to compress the spring c211. The elastic effect of the spring c211 further disperses the impact force. The multiple elastic structures work together to achieve anti-collision protection.

[0038] The quick-release mechanism 25 can be disassembled and installed by pressing two sets of locking blocks 252. When pressed, the locking blocks 252 squeeze the spring a253 and disengage from the slot of the sliding frame 26, which can separate the sliding frame 26 from the connecting block 251. After releasing, the spring a253 pushes the locking blocks 252 to reset and engage with the slot of the sliding frame 26, thus achieving quick disassembly and assembly. When a certain anti-collision mechanism 2 is damaged and needs to be replaced or repaired, there is no need to disassemble the whole thing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
