[0021] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Provided by Figures 1 to 5 , a drone with a collision buffer mechanism provided by the present utility model includes a drone body 1 and four rotors 2 installed at the four corners of the drone body 1. The four rotors 2 are all connected to the drone body 1 through wires. Two movable frames 3 are installed at the bottom of the drone body 1. Two buffers 4 are installed between the middles of the two movable frames 3. And both ends of the bottoms of the two movable frames 3 are movably connected to inclined rods 5. The tops of the four inclined rods 5 are all fixedly installed with arc-shaped bending protection plates 6. The four arc-shaped bending protection plates 6 are respectively located on the sides of the four rotors 2 to provide anti-collision protection for the rotors 2.​

[0023] Both movable frames include a lower cross bar 7, two side plates 8 and an upper cross bar 9. The upper parts of the two side plates 8 are respectively rotatably connected to the two ends of the upper cross bar 9. The lower parts of the two side plates 8 are respectively fixedly connected to the two ends of the lower cross bar 7. The bottoms of the four inclined bars 5 are respectively rotatably connected to the ends of the two lower cross bars 7. Adjusting rods 11 are respectively rotatably connected between the upper parts of the four side plates 8 and the lower parts of the four inclined bars 5. Two support rods 12 are fixedly connected between the upper parts of the inclined bars 5 and the lower parts of the arc-shaped curved protection plate 6, so that the arc-shaped curved protection plate 6 can be effectively installed.

[0024] Two rotating blocks 13 are respectively rotatably connected to the surfaces of the two upper cross bars 9. Bearings 14 are installed at the tops of the rotating blocks 13. The inner rings of the bearings 14 are fixedly connected with threaded pins 15. The threaded pins 15 can be rotationally adjusted. Four first internal threaded tubes 16 are fixedly installed at the bottom of the drone limb 1. The four threaded pins 15 are respectively threadedly connected to the four first internal threaded tubes 16, so that the movable frame 3 can be effectively installed and disassembled.

[0025] Fixed rods 17 are fixedly connected between the two side plates 8 on each movable frame 3. Two second internal threaded tubes 18 are respectively rotatably connected to the surfaces of the two fixed rods 17. The two buffer members 4 both include a plug rod 19 and a socket tube 20. Connecting threaded ends are respectively provided at one ends of the plug rod 19 and the socket tube 20. The plug rod 19 and the socket tube 20 are respectively threadedly connected to the two second internal threaded tubes 18 on the opposite surfaces of the two fixed rods 17 through the connecting threaded ends. The other end of the plug rod 19 is inserted into the inside of the socket tube 20. A slider 21 is fixedly installed at the end of the plug rod 19 located inside the socket tube 20. Springs 22 are installed on the inside of the socket tube 20 and the surface of the plug rod 19 located inside the socket tube 20. The slider 21 is located between the two springs 22, so that effective buffering can be carried out and the two movable frames can be kept effectively stable after installation;

[0026] When the drone collides during flight, the arc-shaped curved protection plate 6 will contact the collision object, thus preventing the rotor 2 from being damaged by the collision, improving the flight safety of the drone. When the arc-shaped curved protection plate 6 is collided, it will drive the inclined bar 5 to rotate, so that the inclined bar 5 squeezes the side plate 8 through the adjusting rod 11, so that the side plate 8 pushes the plug rod 19 or the socket tube 20 to move through the fixed rod 17 and the second internal threaded tube 18, so that the slider 21 compresses one of the springs 22 to play a buffering role;

[0027] When this drone lands, the two lower crossbars 7 will come into contact with the ground and be squeezed by gravity, driving the two side plates 8 thereon to rotate. The rotation of the side plates 8 will pull the insertion rod 19 and the insertion tube 20 to move through the fixed rod 17 and the second internal threaded tube 18, so that the slider 21 compresses the other spring 22 to play a buffering role, thus effectively protecting the drone. The rotation of the side plates 8 will push the inclined rod 5 to rotate through the adjusting rod 11, so that the inclined rod 5 drives the arc-shaped curved protective plate 6 away from the rotor 2 to avoid collision between the arc-shaped curved protective plate 6 and the rotor 2.

[0028] At the same time, the two movable frames 3 can be effectively disassembled to facilitate the carrying of the drone. The disassembly operation of the two movable frames 3 can be completed by rotating the threaded pin 15 to separate it from the first internal threaded tube 16, enabling the drone body 1 to be conveniently boxed and carried. Then, by rotating the insertion rod 19 and the insertion tube 20 to separate them from the second internal threaded tube 18, the two movable frames 3 can be separated to facilitate disassembly and carrying.

[0029] This drone has an anti-collision protection and landing buffering structure. The anti-collision protection structure can effectively protect the protruding rotors, effectively ensuring the safety of the drone flight. The landing buffering structure can buffer and protect the landing of the drone, avoiding damage caused by hard landing to the drone. At the same time, the structure of this drone with a collision buffering mechanism is simple in design, convenient and easy to use, stable and reliable, and its performance can meet the usage requirements of the safe flight of the drone.

[0030] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
