A multi-rotor unmanned aerial vehicle

Abstract

The invention relates to a multi-rotor unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a vehicle body, vehicle arms, motors, rotary wings and foot supports. The vehicle body is provided with a hanging support. The hanging support is provided with a hook. The lower part of the hook is provided with protective bars used for protecting the rotary wings. The hanging support is connected to a hanging support connecting port in the vehicle body through a hanging support connecting head at the lower end of the hanging support. During using, the multi-rotor unmanned aerial vehicle can be hung to an object on high through the hook, for example the multi-rotor unmanned aerial vehicle can be hung to electric wires in the air. Electricity is not needed to supply the lift force of the multi-rotor unmanned aerial vehicle in a hung state, and most of electricity of a battery can be supplied to devices carried by the multi-rotor unmanned aerial vehicle, thus greatly prolonging the working time of working devices in a descending and lifting process. The multi-rotor unmanned aerial vehicle can be widely used for fixed-point monitoring in the air, monitoring, camera shooting, environment protection monitoring, field scientific investigation, case reconnaissance, city management, courtyard security and protection, vehicle thievery prevention, express delivery, and other fields.

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 9 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. , High-voltage lines, bridges, dams and road inspections, search and rescue, express delivery, etc. have been applied. Existing multi-rotor UAVs mainly have the following disadvantages: because they rely on the battery on board to provide electrical energy when hovering in the air, the battery life is short, and most multi-rotor UAVs that rely on battery power can only continue to fly for 10 days at a time ~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 satisfyin...
