Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: when the prior art is in use, when the UAV malfunctions and stops running in the air, if it falls directly and touches the ground , it will lead to damage to the UAV, and the current UAV usually hangs equipment such as a camera, and the existing UAV landing gear cannot be adjusted according to the height of the hanging equipment when it is in use, which may lead to serious problems. The high hanging equipment is in contact with the raised objects on the ground, causing damage to the hanging equipment

Abstract

The invention relates to the technical field of undercarriages, and discloses a liftable undercarriage which comprises an unmanned aerial vehicle body, a single chip microcomputer is arranged in the unmanned aerial vehicle body, driving mechanisms are arranged at the four corners of the top side of the unmanned aerial vehicle body, and a rotating speed sensor is arranged on one side of each driving mechanism. And the bottom side of the rotating speed sensor is fixedly installed on the top side of the unmanned aerial vehicle body, a storage bin is fixedly installed on the top side of the unmanned aerial vehicle body, and a parachute is arranged in the storage bin. Through arrangement of the rotating speed sensor, an electromagnetic valve, a sucking pump, an air bag and the parachute, during use, when the unmanned aerial vehicle body stops running due to a fault in the flight process, the rotating speed sensor detects that the driving mechanism stops rotating, so that the single chip microcomputer controls the sucking pump and the electromagnetic valve to inflate air into the air bag and the storage bin; and the parachute is opened while the airbag expands, so that the unmanned aerial vehicle body stably falls, and the unmanned aerial vehicle body is prevented from being broken.

Description

technical field [0001] The invention relates to the technical field of landing gear, in particular to a liftable landing gear. Background technique [0002] With the development of science and technology, multi-rotor drones have gradually appeared in people's daily life. In recent years, drones have been constantly updated, and their structures and functions have been continuously enriched and optimized. [0003] The existing patent (publication number: CN212921957U) is an unmanned aerial vehicle landing gear device, which relates to the technical field of unmanned aerial vehicles. A landing gear device for an unmanned aerial vehicle, including a body, the body includes two landing units, and the two landing units are respectively located on both sides of the body; the landing unit includes a bottom rod and a cylinder connected to each other; Connection; the cylinders of the two lifting and landing units realize gas communication through pipes. The landing gear device of t...
