Abstract

The invention provides a multi-rotor-wing unmanned plane which comprises a flight control assembly, a rack, a plurality of motors, a plurality of motor seats and a plurality of propellers. The rack comprises a machine body, a plurality of supports, a plurality of first connectors and a plurality of second connectors. The flight control assembly is arranged on the machine body, each support comprises a supporting rod and a swing rod, the supporting rods are connected with the machine body, one end of each swing rod is movably connected with the corresponding supporting rod through the corresponding first connector, and the included angles between the supporting rods and the swing rods are changeable; the other ends of the swing rods are provided with motor seat mounting portions, the motor seats are provided with connection shafts, the connection shafts are connected with the motor seat mounting portions, the second connectors are connected with the connection shafts and the motor seat mounting portions respectively, the motors are connected with the motor seats, and the propellers are connected with the motors. The multi-rotor-wing unmanned plane has the advantages of being simple in structure, flexible and convenient in angle adjustment operation, wide in application range, high in flight stability and high in interference resistance.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a multi-rotor unmanned aerial vehicle with stable operation. Background technique [0002] In recent years, multi-rotor UAVs have become one of the hot spots in the research field of emerging micro UAVs. Multi-rotor drones have the advantages of small size, light weight, low cost, flexible operation and high safety, and can be widely used in aerial photography, detection, search and rescue, exploration and other fields. [0003] The multi-rotor drone is driven by multiple independent motors, the motors are connected to the frame, and the propellers are connected to the motors. Generally, the frame and the fuselage of the multi-rotor UAV are arranged in the same plane, and the propellers are arranged horizontally. Therefore, the propeller of the multi-rotor UAV is set in parallel with the fuselage. This structure responds slowly to external disturbances and takes a long time to adju...
