Abstract

A falling-resistant and anti-drifting unmanned aerial vehicle has a main body and at least one rotor wing thereon. Both sides of the main body have a wing with an airbag filled with gas lighter than air. Bulges protruding downwards are arranged at the bottoms of the airbag. The two airbags are at the same height symmetrically arranged based on the main body. The airbag can function as an undercarriage when the aircraft lands down, and as a buffer when crash landing and then reduce damage to the main body. If the aircraft falls in water, the aircraft can float on the water to avoid damage caused by sinking. As bulges protruding downwards are arranged at the bottoms of the airbags, in spraying operation, side wing can be relatively well baffled by the bulges in case of side wing blowing in the flying process, resulting in less droplets draft.

First claim

The invention claimed is:

1. An unmanned aerial vehicle comprising:
a main body,
airbags connected with the main body and respectively arranged on two opposite sides of the main body;
wings respectively arranged on two opposite sides of the main body and the airbags are fixed on the wings, wherein the main body is connected with the wings through a first connecting beam and second connecting beams; and
support frameworks arranged inside the airbags, wherein the first connecting beam and the second connecting beams penetrate through the airbags and the first connecting beam and the second connecting beams are both connected with the support frameworks;
wherein the first connecting beam penetrates through two sides of the bottom of the main body; the wings on two sides of the main body are respectively fixed on the first connecting beam on two sides of the main body; the main body is rotated around the first connecting beam; clamping grooves are respectively arranged on two opposite sides of the bottom of the main body; the end of each second connecting beam connected with the main body is clamped inside each clamping groove and the second connecting beams is moved inside the clamping grooves.

2. The unmanned aerial vehicle according to claim 1 , wherein at least one rotor wing is arranged on the main body and the airbags take the shape of an airship.

3. The unmanned aerial vehicle according to claim 1 , wherein bulges protruding downwards are arranged at the bottoms of the airbags.

4. The unmanned aerial vehicle according to claim 1 , wherein the airbags are filled with gas lighter than air.

5. The unmanned aerial vehicle according to claim 1 , wherein a plurality of wing ribs which are arranged in a same direction are arranged inside the wings; the outer sides of the wing ribs are wrapped by soft sheath; a first through hole matched with the first connecting beam and second through holes matched with the second connecting beams are respectively formed in each wing rib; the first connecting beam penetrates through the first through hole of each wing rib and the second connecting beams penetrate through the second through holes of the wing ribs.

6. The unmanned aerial vehicle according to claim 1 , wherein a buckle component is arranged at the bottom of the main body, through which the first connecting beam is fixed at the bottom of the main body.
