Abstract

The invention discloses an unmanned aerial vehicle which comprises a vehicle body assembly, a vehicle arm device, a power device and a driving device, the two length ends of the vehicle arm device arethe inner end and the outer end correspondingly, the inner end of the vehicle arm device is installed on the vehicle body assembly, the power device is installed at the outer end of the vehicle arm device, and the power device comprises a power unit; the power unit comprises a power motor and a propeller installed on the power motor, the driving device comprises a driving mechanism and a pull wire, the driving mechanism is installed on the fuselage assembly, and the pull wire is connected with the driving mechanism and the power device so that the driving mechanism can drive the power unit torotate around a preset axis relative to the vehicle arm device through the pull wire. According to the unmanned aerial vehicle, the structural compactness of the unmanned aerial vehicle is improved,and the weight of the vehicle arms is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle. Background technique [0002] With the development of drone technology, people can use drones to complete many tasks, such as spraying fire extinguishing fluid in forest fires, aerial photography, power inspection, environmental monitoring and disaster inspection and many other tasks. The unmanned aerial vehicle in the related art includes a fuselage, a machine arm, a propeller and a driver. The propeller is arranged on the outer end of the machine arm. The propeller includes a rotation axis, and the propeller is rotatable around the rotation axis. The central axis of the aircraft rotates around the pivot axis perpendicular to the central axis to correct the angle of the fuselage and adapt to different flight state requirements. However, since the driver needs to drive the propeller, the driver is usually placed close to the propeller...
