Anti-collision device based on large multi-rotor unmanned aerial vehicle

Abstract

An anti-collision device based on a large multi-rotor unmanned aerial vehicle is disclosed in the invention, and comprises a first protection mechanism and a second protection mechanism, the first protection mechanism is connected with the vehicle arm of the large multi-rotor unmanned aerial vehicle through an adapter piece, and the second protection mechanism is connected with the motor mounting base of the large multi-rotor unmanned aerial vehicle through a motor base; and the first protection mechanism is connected with the second protection mechanism through a second protection vertical rod. The anti-collision protection function can be provided for the large multi-rotor unmanned aerial vehicle, the safety performance of the large multi-rotor unmanned aerial vehicle during flying is improved, the structure is reasonable and light, and the manufacturing cost is low. Due to the lightweight structural design, reliable safety guarantee can be provided for the unmanned aerial vehicle to the maximum extent under the conditions that the flight power performance of the unmanned aerial vehicle is not greatly lost and the flight stability of the unmanned aerial vehicle is not reduced, and the structure can be widely applied to large multi-rotor unmanned aerial vehicle structures.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-collision device based on a large multi-rotor unmanned aerial vehicle. 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. Nowadays, there is a great market demand for drones in the civilian field. At present, there are broad application spaces in various fields such as aerial photography, agricultural plant protection, express delivery, disaster relief, surveying and mapping, news reports, and power inspections. However, due to the high-speed rotation of the blades of the multi-rotor UAV, there is a possibility of collision with the aircraft during the flight, resulting in personal injury or damage to the fuselage, and there are certain safety hazards. At present, most drones used on the market will be equipped with anti-collision ...
