The invention relates to an unmanned aerial vehicle design, in particular to an unmanned aerial vehicle device. The unmanned aerial vehicle device comprises an unmanned aerial vehicle. The unmanned aerial vehicle comprises a vehicle body, four wings, electric motors, propellers, a first driving device, a second driving device, a power distribution device and a control device, wherein each two of the four wings are symmetrically arranged at the top of the front end of the vehicle body and the bottom of the rear end of the vehicle body; the four wings are provided with unfolding states and folding states; the electric motors are arranged at the end parts of one ends, far away from the vehicle body, of the wings in a rotatable manner; the propellers are fixedly arranged on driving shafts of the electric motors; the first driving device is used for driving the wings to rotate; the second driving device is used for driving the electric motors to rotate; the power distribution device is used for providing electric energy to the electric motors, the first driving device and the second driving device; and the control device is used for controlling the first driving device, the second driving device and the electric motors to act. The unmanned aerial vehicle device has the advantages that the structure is simple, the unmanned aerial vehicle device can be rapidly converted between the unfolding state and the folding state, the dimension of the unmanned aerial vehicle can be furthest reduced in the folded state so that the unmanned aerial vehicle is convenient for individual soldier to carry, and the unmanned aerial vehicle device can give consideration to both high speed flying and static hovering.
