A kind of unmanned aerial vehicle and working method thereof

Abstract

The invention relates to an unmanned aerial vehicle and its working method, comprising a fuselage of the aircraft, a plurality of support arms fixedly connected to the fuselage, and a propeller fixed on the upper end of the outer side of the support arm; The battery, the controller for controlling the operation of the aircraft; the foldable landing gear hinged with the support arm is arranged below the outer end of the support arm, and the landing gear includes a hollow main cylinder with a hole at one end, and a telescopic sleeve slidingly connected with the main cylinder. Rod, the inner wall of the main cylinder is radially symmetrically provided with two electrodes, the electrodes are electrically connected to the controller, the telescopic rod is made of conductive metal, when the telescopic rod shrinks into the main cylinder, the two electrodes pass through the telescopic rod Connection and conduction; the unmanned aerial vehicle controls the electrode on / off by moving the telescopic rod up / down during take-off and landing, and the controller controls the propeller to rotate or stop through the electrical signal introduced by the electrode. The response is sensitive and safe, and it can effectively avoid After the UAV landed, the propeller continued to rotate.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an unmanned aerial vehicle and a working method thereof. Background technique [0002] Unmanned aerial vehicle is an unmanned aerial vehicle controlled by radio remote control equipment and self-provided program control device. At present, the unmanned aerial vehicle generally includes the fuselage, the propeller that provides flight power, etc. After the existing unmanned aerial vehicle falls abnormally, the propeller is still in the rotating state, and it is easy to be entangled by foreign objects and cause damage to the motor; or when When the unmanned aerial vehicle is parked at a distance, there is a problem that the unmanned aerial vehicle is not shut down in time and the child is injured by the propeller; in addition, the propeller of some unmanned aerial vehicles can start to rotate after being folded, which has a great potential safety hazard. . SUMMARY OF THE INVENTION [00...

AI Technical Summary

Problems solved by technology

[0002] Unmanned aerial vehicle is an unmanned aerial vehicle controlled by radio remote control equipment and self-contained program control device. Compared with manned aircraft, it has small size, low cost, easy to use, low requirements for combat environment, and high battlefield survivability. Strong and other advantages; at present, unmanned aerial vehicles generally include the fuselage, the propeller that provides flight power, etc., after the existing unmanned aerial vehicle falls abnormally, the propeller is still in the rotating state, and it is easy to be entangled by foreign objects and cause damage to the motor; or when When the unmanned aerial vehicle landed far away, sometimes the unmanned aerial vehicle did not shut down in time, causing children to be injured by the propeller; in addition, the propeller of some unmanned aerial vehicles can still start to rotate after being folded, which has a greater safety hazard
