Abstract

The invention relates to an unmanned aerial vehicle recovery damping airbag. The unmanned aerial vehicle recovery damping airbag comprises a vehicle body, airfoils and an airbag buffer device, the airfoils are fixedly mounted on the vehicle body, and the airbag buffer device is mounted on the vehicle body and comprises a collection box, an air inlet and outlet pipeline, an air inlet fan and an airbag body. The unmanned aerial vehicle recovery damping airbag is specifically structurally characterized in that the collection box with a lower opening is fixedly mounted on one airfoil, the air inlet and outlet pipeline is mounted between the collection box and the vehicle body, one end of the air inlet and outlet pipeline is connected with the air inlet fan fixedly mounted on the vehicle body, and the other end of the air inlet and outlet pipeline extends into the collection box and is hermetically connected with the airbag body folded in the collection box. The airbag comprises an inflatable bag body made of inelastic, soft and airtight materials, and the airbag buffer device can not only absorb and release sufficient impact energy and reduce landing impact load of an unmanned aerial vehicle, but also avoid rebound during landing, so that the unmanned aerial vehicle can descend and ground stably during landing and lands safely.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and relates to a recovery device for a small unmanned aerial vehicle, in particular to a shock-absorbing airbag for recovery from an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and its own program control device. It can be used for aerial reconnaissance, surveillance, communication, anti-submarine, electronic interference, etc. Power inspection, aerial photography and other fields, and play an important role. [0003] At present, the more commonly used recovery method for small unmanned aircraft is parachute recovery. Under the action of the recovery parachute, the drone will reduce the stable landing speed of the aircraft, and then use the landing buffer device to slow down the impact energy brought by landing. Reduce landing g to avoid damage. The landing buffer methods of the UAV parachute recovery syste...
