Vertical take-off and landing unmanned aerial vehicle and driving method thereof

Abstract

The invention discloses a vertical take-off and landing unmanned aerial vehicle and a driving method thereof. The vertical take-off and landing unmanned aerial vehicle has a vehicle body and a driving unit, the driving unit comprises a first driving mechanism and two second driving mechanisms, and the two second driving mechanisms are distributed on the two sides of the vehicle body; the first driving mechanism and the second driving mechanisms are distributed in a three-point manner; wherein the first driving mechanism comprises a thrust engine; the second driving mechanism comprises a propeller used for rotating when the unmanned aerial vehicle takes off and lands, and a rotating shaft of the propeller is vertically distributed; a connecting rod, wherein one end of the connecting rod is connected with a rotating shaft of the propeller, and the other end is connected with the fuselage through a first hinge piece; a pushing structure which is used for pushing the connecting rod to rotate along the first hinge piece. Firstly, the driving units distributed in a three-point mode are beneficial to improving the lifting stability of the unmanned aerial vehicle; and secondly, the second driving mechanism can be folded and unfolded, and the flat flying resistance can be obviously reduced after the second driving mechanism is folded. In addition, stable lifting of the unmanned aerial vehicle is achieved without a ducted fan.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular, to a vertical take-off and landing unmanned aerial vehicle and a driving method thereof. Background technique [0002] At present, most of the widely used UAVs with vertical take-off and landing functions are multi-rotor UAVs or ducted fan UAVs, which mainly rely on vertically distributed rotors or ducted fans to provide lift during the lifting phase. Stages rely on the tilt of the rotors or ducted fans to generate forward or other thrust. Therefore, a larger-capacity battery is required to power the rotor or ducted fan to achieve longer flight time and range, which causes the weight of the battery to occupy most of the weight of the body, making the weight of the UAV itself too heavy, and the weight of the task load, Flight time and range are severely limited.
