Multi-rotary-wing single-motor driving structure and unmanned aerial vehicle

Abstract

The invention discloses a multi-rotary-wing single-motor driving structure and an unmanned aerial vehicle. The driving structure comprises a motor, two first rotary wings, two second rotary wings, a first driving shaft and a second driving shaft, wherein the first driving shaft and the second driving shaft are arranged in parallel. The first rotary wings and the second rotary wings are arranged in a staggered mode. The first driving shaft is in transmission connection with the second driving shaft. The motor is in transmission connection with the second driving shaft. The first driving shaft is in transmission connection with the two first rotary wings. The second driving shaft is in transmission connection with the two second rotary wings. The two first rotary wings rotate synchronously in the first direction, meanwhile, the two second rotary wings rotate synchronously in the second direction, and the first direction and the second direction are opposite. According to the multi-rotary-wing single-motor driving structure, driving is conducted by one motor, the transmission series are small, and the transmission efficiency is high.

Description

technical field [0001] The present application relates to an unmanned aerial vehicle, in particular to a multi-rotor single-motor drive structure for an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicles have the characteristics of small size, light weight, low cost, flexible operation and high safety, and can be widely used in aerial photography, monitoring, search and rescue, resource exploration and other fields. [0003] In the prior art, an unmanned aerial vehicle generally includes a plurality of rotors, each of which is driven by a motor, [0004] Its disadvantages are: [0005] 1. Due to the installation of multiple motors, the overall weight of the unmanned aerial vehicle is relatively heavy; [0006] 2. Multiple motors work together, and the high-frequency vibration generated by them can easily affect the clarity of aerial photography; [0007] 3. The synchronization of multiple rotors is difficult to control; [0008] 4. The existi...

Problems solved by technology

[0006] 2. Multiple motors work together, and the high-frequency vibration generated by them can easily affect the clarity of aerial photography;

[0007] 3. The synchronization of multiple rotors is difficult to control;

[0008] 4. Existing multi-axis aircraft use multiple motors to directly drive their respective propellers. In order to maintain balance during the flight of the aircraft, the flight control system needs to frequently change the motor speed

This frequent change of speed causes the motor to consume power faster

And each motor has working efficiency, the more motors there are, the lower the working efficiency of the whole machine will be
