When the device falls, the bottom plate 2 contacts with the ground, the main body 1 generates downward pressure under the action of gravity and inertia, so that the distance between the main body 1 and the movable rod 4 becomes smaller, so that the first spring 5 is compressed, the restoring force of the first spring 5 buffers and absorbs the pressure, meanwhile, the restoring force generated by the deformation of the first spring 5 generates downward pressure on the movable rod 4, so that the distance between the movable rod 4 and the fixed rod 3 becomes smaller, so that the distance between the sliding block 7 and the movable rod 4 becomes smaller, so that the second spring 8 is compressed, the restoring force of the second spring 8 buffers and absorbs the pressure applied to the movable rod 4, meanwhile, the sliding block 7 moves to stretch the third spring 9, the restoring force of the third spring 9 buffers and absorbs the movement of the movable rod 4 of the sliding block 7, and the distance between the movable rod 4 and the fixed rod 3 becomes smaller, thereby enabling the moving rod 4 to press the moving sleeve ring 10 to move, the sleeve ring 10 drives the fourth spring 11 to deform, restoring force of the fourth spring 11 buffers and damps pressure on the sleeve ring 10, thereby buffering and damps pressure on the moving rod 4, meanwhile, the sleeve ring 10 moves, so that the distance between the sleeve ring 10 and the fixed rod 3 is reduced, thereby enabling each push rod 12 to expand outwards, thereby enabling each push rod 12 to move outwards, the push rod 12 drives the rotating shaft 13 and the roller 14 to move, the roller 14 drives the positioning block 15 to move, the positioning block 15 drives the fifth spring 16 to deform, restoring force of the fifth spring 16 buffers and damps pressure on the positioning block 15, meanwhile, the push rod 12 moves, thereby enabling the elastic belt 25 to stretch, buffering and damps pressure on each push rod 12, thereby performing multiple buffering and damping on pressure on the main body 1, thereby achieving a better buffering and damping effect, thereby cushioning and absorbing the vibration generated by the collision between the main body 1 and the ground, avoiding the damage of the main body 1, protecting the main body 1, wherein the rotating shaft 13 is positioned in the locating groove, so that the rotating shaft 13 can only move along the axis direction of the locating groove, thereby limiting the movement of the rotating shaft 13, when the storage device is needed, operating the motor 17, the motor 17 drives the screw rod 18 to rotate, the screw rod 18 drives the movable plate 19 to move, the movable plate 19 drives the movable rod 4 to move, the movable rod 4 drives the second spring 8 and the third spring 9 to move, the second spring 8 and the third spring 9 drive the slide block 7 to move, the slide block 7 drives the connecting rod 6 to move, the connecting rod 6 drives the fixed rod 3 to move, the fixed rod 3 drives the bottom plate 2 to move into the groove, thereby storing the supporting and buffering mechanism, thereby saving the storage space, the supporting buffer mechanism is also protected, when the bottom plate 2 needs to be moved out, only the motor 17 needs to be operated reversely, so that the moving plate 19 moves reversely, and the supporting buffer mechanism moves out of the groove, wherein the sixth spring 23 is in a deformation state, restoring force of the sixth spring 23 generates outward thrust to the lock rod 22, so that the lock rod 22 is clamped into the corresponding lock groove, so that the turntable 20 is locked, so that the screw rod 18 is fixed, so that the moving rod 4 is locked, so that the supporting buffer mechanism is locked, so that the bottom plate 2 keeps a state of being moved out of the main body 1, when storage is needed, the motor 17 rotates to drive the screw rod 18 to rotate, the screw rod 18 drives the turntable 20 to rotate, and driving force of the motor 17 to the turntable 20 is greater than restoring force of the sixth spring 23, so that the motor 17 can drive the turntable 20 to rotate, so that the lock rod 22 moves in each lock groove, when the bottom plate 2 is received in the groove, the motor 17 is stopped, the lock lever 22 is not blocked, and is locked in the corresponding lock groove again under the action of the restoring force of the sixth spring 23, so that the turntable 20 is locked, and the bottom plate 2 is kept in the receiving state.

Compared with the prior art, this unmanned aerial vehicle with descending protect function, realize the flight through main part 1, through supporting the vibrations that buffer gear produced when descending main part 1 and buffering the shock attenuation, realize accomodating through receiving mechanism, compare with current support buffer gear, the device is through setting up multiple buffering shock-absorbing structure, better buffering shock attenuation effect has been realized, thereby realize better protection to main part 1, and accessible receiving mechanism realizes accomodating, storage space has been saved, protect the device simultaneously, and the practicality is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
