[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figure 1 As shown, a UAV anti-collision ring includes a first anti-collision ring 1 and a second anti-collision ring 2, wherein the first anti-collision ring 1 and the second anti-collision ring 2 are connected by a fastening mechanism 3, and the top end of the first anti-collision ring 1 is fixedly connected to a buffer device 4 through an L-shaped rod 101, and the other end of the buffer device 4 is fixedly connected to a clamping device 5.

[0023] Specifically, during the flight of the drone, if the rotor touches an external object, the first anti-collision ring 1 and the second anti-collision ring 2 will first collide with the external object, so that the external object will not contact the rotor running at high speed, and when the anti-collision ring is not in use, the second anti-collision ring 2 can be rotated 180 degrees so that the second anti-collision ring 2 can overlap with the first anti-collision ring 1, saving the space occupied by the device; the second anti-collision ring 2 is clamped on the first anti-collision ring 1 by a U-shaped plug 305, and when the U-shaped plug 305 is inserted into the first through-hole 303 and the second through-hole 304, the U-shaped plug 305 can just clamp the second anti-collision ring 2 so that it will not rotate, and the end of the U-shaped plug 305 can be spirally connected by the screw 307, so that the U-shaped plug 305 will not be displaced in other directions, and can be fixed on the first anti-collision ring 1. When the second anti-collision ring 2 needs to be folded, the screw 307 is rotated to loosen the U-shaped insertion rod 305, so that the U-shaped insertion rod 305 can be pulled out from the through-hole of the first anti-collision ring 1, and then the second anti-collision ring 2 can be rotated to a position overlapping with the first anti-collision ring 1; the buffer device 4 can make the impact force on the anti-collision ring be offset by the elastic deformation of the spring 404. When the anti-collision ring is subjected to impact force, the impact force can be transmitted to the L-shaped rod 101 and the buffer rod 401, and the impact force is continuously transmitted to the piston 402 and the spring 404, so that the buffer rod 401 and the piston 402 can compress the spring 404, converting the impact effect part into the elastic deformation of the spring 404; the clamping ring 504 in the clamping device 5 can clamp the two columns at the lower end of the drone rotor, so that the anti-collision ring can be fixedly installed on the periphery of the drone rotor through the clamping device 5 to protect the drone rotor.

[0024] like Figure 1 As shown, the first anti-collision ring 1 and the second anti-collision ring 2 are both divided into an inner ring and an outer ring, and the inner ring and the outer ring of the second anti-collision ring 2 are both clamped in the gap between the inner ring and the outer ring of the first anti-collision ring 1.

[0025] Specifically, the gap between the inner ring and the outer ring of the first anti-collision ring 1 needs to be greater than the sum of the thickness of the inner ring and the outer ring of the second anti-collision ring 2, and the height of the first anti-collision ring 1 is higher than the height of the second anti-collision ring 2, so that after the second anti-collision ring 2 overlaps with the first anti-collision ring 1, the second anti-collision ring 2 can be completely hidden in the gap of the first anti-collision ring 1, and the second anti-collision ring 2 is set to be slightly larger than a semicircle, and the first anti-collision ring 1 is just set to a semicircle.

[0026] like Figure 2As shown, a fixed shaft 301 is fixedly connected at the ends of the inner ring and the outer ring of the first anti-collision ring 1, and a rotating shaft 302 is rotatably connected at the axis of the fixed shaft 301. The side of the rotating shaft 302 is fixedly connected to the inner ring and the outer ring of the second anti-collision ring 2. Two groups of first through-holes 303 and two groups of second through-holes 304 are respectively provided at the ends of the outer ring and the inner ring of the first anti-collision ring 1. U-shaped insertion rods 305 are inserted into the first through-holes 303 and the second through-holes 304. Two groups of screw holes 306 are provided at the ends of the U-shaped insertion rod 305. A screw rod 307 is rotatably connected in the screw hole 306.

[0027] Specifically, the distance between the two ends of the U-shaped rod 305 is exactly the thickness of the second anti-collision rod, and the second anti-collision ring 2 is clamped on the first anti-collision ring 1 by the U-shaped rod 305. When the U-shaped rod 305 is inserted into the first through-hole 303 and the second through-hole 304, the U-shaped rod 305 can just clamp the second anti-collision ring 2 so that it will not rotate, and the end of the U-shaped rod 305 can be spirally connected by the screw 307, so that the U-shaped rod 305 will not be displaced in other directions and can be fixed on the first anti-collision ring 1. When the second anti-collision ring 2 needs to be folded, the screw 307 is rotated to loosen the U-shaped rod 305, so that the U-shaped rod 305 can be pulled out from the through-hole of the first anti-collision ring 1, and then the second anti-collision ring 2 can be rotated to a position overlapping with the first anti-collision ring 1.

[0028] like Figure 3 As shown, the end of the L-shaped rod 101 is fixedly connected to a buffer rod 401, the end of the buffer rod 401 is fixedly connected to a piston 402, the other end of the piston 402 is fixedly connected to a spring 404, the piston 402 and the spring 404 are placed in a buffer cavity 403, and the other end of the spring 404 is fixedly connected to one end inside the buffer cavity 403.

[0029] Specifically, the buffer device 4 can offset the impact force received by the anti-collision ring by the elastic deformation of the spring 404. When the anti-collision ring is subjected to the impact force, the impact force can be transmitted to the L-shaped rod 101 and the buffer rod 401, and the impact force is continuously transmitted to the piston 402 and the spring 404, so that the buffer rod 401 and the piston 402 can compress the spring 404, and convert the impact effect part into the elastic deformation of the spring 404.

[0030] like Figure 4 As shown, the other end of the outside of the buffer cavity 403 is fixedly connected to a connecting rod 405, the other end of the connecting rod 405 is vertically fixedly connected to a straight rod 501, the other side of the straight rod 501 is fixedly connected to a first toughness bar 502 and a second toughness bar 503, and the first toughness bar 502 and the second toughness bar 503 are jointly fixedly connected to a clamping ring 504.

[0031] Specifically, the clamping ring 504 in the clamping device 5 can clamp the two columns at the lower end of the drone rotor, so that the anti-collision ring can be fixedly installed on the periphery of the drone rotor through the clamping device 5 to protect the drone rotor.

[0032] The working principle of the present invention is as follows: during the flight of the UAV, if the rotor touches an external object, the first anti-collision ring 1 and the second anti-collision ring 2 will first collide with the external object, so that the external object will not touch the rotor in high-speed operation, and when the anti-collision ring is not in use, the second anti-collision ring 2 can be rotated 180 degrees so that the second anti-collision ring 2 can overlap with the first anti-collision ring 1, saving the space occupied by the device; the second anti-collision ring 2 is clamped on the first anti-collision ring 1 by a U-shaped insertion rod 305, and when the U-shaped insertion rod 305 is inserted into the first through-hole 303 and the second through-hole 304, the U-shaped insertion rod 305 can just clamp the second anti-collision ring 2 so that it will not rotate, and the end of the U-shaped insertion rod 305 can be spirally connected by the screw 307, so that the U-shaped insertion rod 305 will not be displaced in other directions, and can be fixed on the first anti-collision ring On the impact ring 1, when the second anti-collision ring 2 needs to be folded, the screw 307 is rotated to loosen the U-shaped insertion rod 305, so that the U-shaped insertion rod 305 can be pulled out from the through-hole of the first anti-collision ring 1, and then the second anti-collision ring 2 can be rotated to a position overlapping with the first anti-collision ring 1; the buffer device 4 can make the impact force exerted on the anti-collision ring be offset by the elastic deformation of the spring 404. When the anti-collision ring is subjected to impact force, the impact force can be transmitted to the L-shaped rod 101 and the buffer rod 401, and the impact force is continuously transmitted to the piston 402 and the spring 404, so that the buffer rod 401 and the piston 402 can compress the spring 404, and convert the impact effect part into the elastic deformation of the spring 404; the clamping ring 504 in the clamping device 5 can clamp the two columns at the lower end of the drone rotor, so that the anti-collision ring can be fixedly installed on the periphery of the drone rotor through the clamping device 5 to protect the drone rotor.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
