Problems solved by technology

[0003] After the drone enters the horizontal flight stage, although the rear rotor stops working, it is still in an extended state, which increases the air resistance encountered by the drone during flight, so the speed of the drone's horizontal flight is low

Abstract

The present invention proposes an unmanned aerial vehicle, which comprises a fuselage, wings, a first power unit and a second power unit, and the wings are arranged on opposite sides of the fuselage middle; the first power unit includes two front rotors , the two front rotors are arranged on opposite sides of the front end of the fuselage respectively; The power unit includes two rear rotors, and the two rear rotors are respectively arranged on opposite sides of the rear end of the fuselage; the rear rotor includes a second connecting rod and a second driving assembly, one end of the second connecting rod is provided with a second driving assembly, and the other end The fuselage is connected; one of the first connecting rod and the second connecting rod is rotatably connected with the fuselage and can rotate along its axial direction, and the other is rotatably connected with the fuselage to have a folded state and an extended state. The technical scheme of the invention improves the horizontal flight speed of the drone.

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] The fuselage of an existing unmanned aerial vehicle is provided with a pair of front rotors and a pair of rear rotors. Among them, during the vertical take-off stage of the UAV, the front rotor and the rear rotor work at the same time to provide the UAV with rising lift; when the UAV rises to a certain height, it enters the transition flight stage, the front rotor turns to the horizontal position, and the rear rotor Gradually reduce the speed until it stops working; the UAV enters the stage of horizontal flight, at this time the front rotor continues to work to provide the UAV with thrust for horizontal flight, and then the rear rotor stops working. [0003] After the UAV enters the horizontal flight stage, although the rear rotor stops working, it is still in an extended state, which increases the air re...
