Detailed Description

The utility model discloses an unmanned aerial vehicle with prevent falling shockproof structure, including

fuselage

1, 1 inside battery and the trigger release 2 of being equipped with of fuselage, trigger release 2 and include control module, stand-by power supply, gravity acceleration sensor and trigger are connected with control module, and even interval is equipped with three above tilt up's wing 3 all around in the side of fuselage 1, and rotating electrical machines 4 is installed to 3 terminal up ends of every wing, at rotating electrical machines 4's output fixedly connected with screw 5, wherein trigger release 2 and rotating electrical machines 4 all with battery electric connection.

The upper part of the machine body 1 is connected with a protection bin 11 through an elastic support, the top of the protection bin 11 is provided with a parachute device, the parachute device comprises a parachute bag 13, a parachute body 14 and an ejection device 15, the parachute bag 13 is arranged in the center of the top of the protection bin 11, the parachute body 14 is arranged in the parachute bag 13, and the ejection device 15 is arranged below the parachute body 14 and connected through a trigger release device 2; evenly the interval is equipped with four shockproof supporting legs 16 on the terminal surface under fuselage 1, is fixed with the connective bar 17 at shockproof supporting leg 16's lower extreme, the lower extreme fixedly connected with buffering post 18 of connective bar 17, the outside movable sleeve of buffering post 18 is equipped with buffer tube 6, and buffer tube 6 is inside to be equipped with damping spring 19, damping spring 19's top and the interior diapire fixed connection of buffering post 18 bottom fixed connection, bottom and buffer tube 6, at the bottom fixedly connected with chassis 7 of buffer tube 6, at the lower fixed surface of chassis 7 and be connected with connection piece 8, the surface of connection piece 8 has gyro wheel 10 through axis of rotation 9 swing joint.
