Embodiment Construction

[0052]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0053]It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or a central component may also exist. When a component is considered to be "connected" to another component, it can be directly connected to another component or there may be a centered component at the same time. When a component is considered to be "installed on" another component, it can be directly installed ...

Abstract

The invention provides an unmanned aerial vehicle which comprises a central part and a plurality of vehicle arms extending from the central part, each vehicle arm is provided with at least one power device, and each power device comprises a rotor wing and a power motor for driving the rotor wing to rotate, the unmanned aerial vehicle is characterized by further comprising one or more rotor wing protection covers, the rotor wing protection covers are arranged outside the area of the rotating surfaces of the rotor wings, and the one or more rotor wing protection covers are connected with at least one of the central part and the plurality of vehicle arms; and the unmanned aerial vehicle further comprises one or more sensors, at least one of the one or more sensors is arranged at the tail endof at least one of the multiple vehicle arms and located outside the range defined by the rotor wing protection covers.

Description

Technical field[0001]The invention relates to an unmanned aerial vehicle, particularly an unmanned aerial vehicle with obstacle avoidance function.Background technique[0002]UAV is an unmanned aerial vehicle that is operated by radio remote control equipment or remote control device to perform missions. General UAVs are equipped with navigation and flight control systems, program control devices, and power supply equipment. In recent years, UAVs have been developed and applied in many fields, especially the hotspots of general industrial and military research. Military significance and economic status.[0003]UAVs mainly have the advantages of relatively low cost, no danger of casualties, strong survivability, and good maneuverability. But also because it is unmanned, the drone can only fly by the aircraft's own flight control system or the instructions of the ground control center. Then when it encounters obstacles such as high-voltage cables, trees or buildings, especially the use of...
