The invention discloses an unmanned aerial vehicle which comprises a vehicle body and vehicle arms. The vehicle arms are rotationally connected to the vehicle body and can be unfolded in a first posture relative to the vehicle body. The first posture indicates that the unmanned aerial vehicle is in the state capable of flying. The vehicle arms can be folded in a second posture relative to the vehicle body. When the vehicle arms are in the second posture, the vehicle arms and propellers on the vehicle arms are drawn close to the vehicle body, and the unmanned aerial vehicle is in the state incapable of flying. First limiting structures used for keeping the vehicle arms in the first posture and pop-up pieces used for unfolding the vehicle arms are arranged between the vehicle arms and the vehicle body. In the use process, when a user releases the vehicle arms, the vehicle arms can be automatically unfolded relative to the vehicle body under the action of the pop-up pieces, and when the first limiting structures between the vehicle arms and the vehicle body act, the vehicle arms are unfolded in the first posture; and after operation is finished, the vehicle arms only need to be pushedin the direction of the vehicle body so as to be drawn close to the vehicle body and folded, operation is convenient, the space occupied by the unmanned aerial vehicle in the non-flying state can bereduced, and the user can conveniently store and protect the unmanned aerial vehicle.
