Abstract

The invention discloses a falling protection device for an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The problem that a device is damaged if bounce is generated is solved. The device specifically comprises a machine body, a placement chamber is fixed to the outer wall of the bottom of the machine body through screws, four placement grooves are formedin the side wall of the placement chamber, airbags are placed on the inner walls of the placement grooves, a buffer chamber is arranged on the inner wall of the placement chamber, supporting columns are arranged on the inner wall of the buffer chamber, and impact columns are welded to the outer walls of one sides of the supporting columns. Through the arrangement of the placement chamber, when a gravity detector detects that the device vertically falls, the controller is operated to open the airbags, then the airbags can form a circular ring around the placement chamber to protect the bottom of the machine body, and when the machine body makes contact with the ground, the airbags are impacted and then a connecting circular plate makes contact with the ground and the second spring is compressed, at the moment, an impact rod rushes into the soil; and if the device rebounds, elastic claw hooks on the impact column can grab the ground to generate reverse acting force, so that the situationthat the device is damaged due to the fact that the rebound amplitude of the device is too large is prevented.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a fall protection device for drones. Background technique [0002] Small drones at home and abroad have been widely used in civilian and military fields, such as disaster monitoring in disaster areas, aerial photography of TV stations, power line inspection, weather detection, target detection, etc.; Both may cause the aircraft to lose control and crash, thereby causing damage to the airframe itself and the airborne equipment. Since the drones and airborne remote sensing equipment are of high value at this stage, once a crash occurs, it will cause huge property value. The utility model relates to a fall protection device for an unmanned aerial vehicle, which can protect the fallen unmanned aerial vehicle. [0003] After retrieval, the Chinese patent application number is 201910963563.3, which discloses a UAV fall protection device, including a fuselage, with wings equidistant fro...
