Unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle. The unmanned aerial vehicle comprises a machine body, wherein a plurality of machine arms are uniformly distributed on the periphery of the machine body, a rotor wing is arranged at the end, away from the machine body, of each machine arm, supporting legs which are consistent with the number of the machine arms and driving parts corresponding to the supporting legs are arranged on the bottom surface of the machine body, the end part of each supporting leg is hinged to the side wall of the machine body, the driving parts are used for driving the supporting legs to rotate around a hinge point, the supporting legs can swing to be attached to the side wall of the machine arms or are supported on the bottom surface of the machine body, and the end part, away from the hinge point, of the supporting legs is used for being in contact with ground. When the unmanned aerial vehicle is about to be landed, the end, away from the machine body, of the supporting legs can be in contact with the ground firstly, so that the traditional unmanned aerial vehicle is avoided, the machine body and the machine arms can collide with the ground when a flying state is converted into a stagnation state, and the actual service life of the whole unmanned aerial vehicle is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle design, in particular, to an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] At present, the structure of the more common drones on the market includes the body. Several arms are arranged around the body. The arms are evenly distributed along the periphery of the body. The end of each arm facing away from the body is equipped with a rotor. [0004] Based on the above structure, the state of the UAV is divided into a flight state and a stagnation state; in the flight state, all rotors will rotate, the rotors will be pushed down by the air, and the entire body will fly in the air; from th...

Problems solved by technology

[0004] Based on the above structure, the state of the UAV is divided into a flight state and a stagnation state; in the flight state, all rotors will rotate, the rotors will be pushed down by the air, and the entire body will fly in the air; from the flight state When turning to a stagnant state, both the body and the arm will inevitably collide with the ground, which in turn will affect the actual service life of the entire drone
