A drone that automatically opens the airbag when the battery runs out and falls

Abstract

The invention provides an unmanned aerial vehicle with an airbag capable of being started automatically in drop due to power exhaust. The unmanned aerial vehicle comprises a fastener strip and a photoelectric switch. The airbag is of four parts, with a circular middle; the four parts of the airbag are bond to oval holes of an airbag box, and the part, out of the airbag box in length, of each partof the airbag is put in the airbag box. An airbag port is formed on the bottom side of the airbag, and is connected with the top end of an air tube through sealing rubber. The lower end of the air tube penetrates a circular hole in the middle of a spacer and then is connected to a hand inflating device. A carbon dioxide steel bottle is fixed to the left end of the inner bottom side of the airbag box through a snap ring by screws. As the airbag is arranged on the bottom side of the body of the unmanned aerial vehicle, a semi-sphere pops out downwards in the circumstance of power interruption ofthe unmanned aerial vehicle; the carbon dioxide steel bottle is opened when the distance from the unmanned aerial vehicle to the floor is equal to 3 meters according to detection, and then gas in thebottle blast into the airbag and the four parts of the airbag extend out of the airbag box to protect the bottom surface and the four sides of the unmanned aerial vehicle in drop so as to prevent theunmanned aerial vehicle from crash.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and more specifically relates to an unmanned aerial vehicle that automatically opens an airbag when the battery runs out and falls. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs can be divided into fixed-wing, rotary-wing, umbrella-wing, flapping-wing and other classifications according to the flying mode. With the development and maturity of wireless technology, control technology and mechanical components, drones can carry a variety of loads to complete various complex tasks, such as aerial observation and shooting, delivery of packages and goods, etc. As the simplest and most intuitive stable control structure, four-rotor consumer drones are gradually showing their prominence in the consumer electronics market. With the lowering of the price t...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a drone that automatically opens the airbag when the battery runs out and falls, so as to solve the problem that the existing drones will encounter insufficient power during the flight process. Flying back with the remaining power, but sometimes the flying distance is long, and the remaining power is not enough to support the flight after the power alarm. After the remaining power is exhausted, it will fall directly and damage the drone.
