Compact unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle, specifically a compact unmanned aerial vehicle, which belongs to the field of aircrafts. The compact unmanned aerial vehicle comprises a propeller hub, rotors and a power output shaft, wherein the rotors are mounted on the propeller hub; and the power output shaft is positioned under the propeller hub and connected with a rotor driving motor. The rotor driving motor is placed on a vehicle frame; a flight control system, a speed regulation controller of the rotor driving motor and a battery are all mounted within the vehicle frame; at least two rotors are respectively mounted at two ends of the vehicle frame; and the two rotors are distributed in the same horizontal plane up and down in high and low forms. The structure size of the unmanned aerial vehicle is integrally reduced; the volume space of the folded unmanned aerial vehicle is further reduced by using a foldable management scheme; by using the unmanned aerial vehicle which adopts a mode of forming the two rotors at different heights to generate an overlapped part, the integral size of the unmanned aerial vehicle is further reduced; without affecting lifting flight balance capacity of the unmanned aerial vehicle, compact design is further performed to provide small volume so as to achieve a portable purpose.

Description

technical field [0001] The invention provides an unmanned aerial vehicle, which belongs to the field of aircraft, and is particularly a compact unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. From a technical point of view, it can be divided into: unmanned helicopter, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airship, unmanned parawing aircraft, etc. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. [0003] For civilian drones, they are generally quadrotor drones. This type of drone is bulky, inconvenient to carry, and cannot be stored and carried. At present, there are more drones that can be stored with quadrotors. , is only for the folding of the rotor part, but because of the quadrotor, the folded...

Problems solved by technology

[0003] For civilian drones, they are generally quadrotor drones. This type of drone is bulky, inconvenient to carry, and cannot be stored and carried. At present, there are more drones that can be stored with quadrotors. , only for the folding of the rotor part, but due to the quadrotor, the folded volume is also very large, which is not conducive to carrying around, and the current drone fuselage has a complex overall structure, large volume, and high cost
