Multi-rotor unmanned aerial vehicle

Abstract

The invention provides a multi-rotor unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a fuselage, fuselage arms, motors and rotors. One end of each fuselage arm is connected with the fuselage. The motors are installed on the fuselage arms. The rotors are installed on rotating shafts of the motors. In addition, hanging frames are further arranged on the side surface of the fuselage or on foot frames under the fuselage. Hanging rods are arranged on the upper portions of the hanging frames, supporting feet are arranged on the lower portions of the hanging frames, when the hanging frames are looked up, the supporting feet are on the inside, and the hanging rods are on the outside. The multi-rotor unmanned aerial vehicle can be hung on street lamp poles and other pole-shaped objects to work through the hanging rods and the supporting feet on the hanging frames, the lifting force does not need to be provided by the rotors for the multi-rotor unmanned aerial vehicle in a hung state, and the working time of airborne equipment in the high positions can be greatly prolonged; and in addition, in the hung state, the attitude and the position of the multi-rotor unmanned aerial vehicle are very stable, and additional control is not needed. The multi-rotor unmanned aerial vehicle can be widely applied in the fields of aerial fixed-point shooting, monitoring, live broadcasting, environmental protection monitoring, case reconnoitering, city management, courtyard security and protection, vehicle theft prevention and the like.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor drones usually have 3 to 8 rotors, especially 4 rotors are the most common. Multi-rotor drones have functions such as vertical take-off and landing, hovering in the air, low-speed flight, inverted flight, side flight, and 360-degree rotation. It is applied in dam inspection, search and rescue, express delivery and so on. Existing multi-rotor UAVs mainly have the following disadvantages: due to relying on the batteries loaded on the machine to provide electric energy when hovering in the air, the battery life is short, and most multi-rotor UAVs that rely on battery power to work can only continue to fly at a time About 10 to 30 minutes, that is to say, the working time of multi-rotor drones in the air is generally only 10-30 minutes, which is far from satisfying people's use of mult...
