The invention discloses a rotor wing unmanned aerial vehicle with telescopic and foldable vehicle arms, and belongs to the field of unmanned aerial vehicles, the rotor wing unmanned aerial vehicle comprises a vehicle body and a plurality of vehicle arms distributed on the vehicle body, a rotor wing assembly is installed at the wingtip of each vehicle arm, and the vehicle arms are telescopic vehicle arms with locking structures; the vehicle arms are pivotally connected with the vehicle body, the vehicle arms ares horizontal relative to the rotating axis of the vehicle body, and a limiting structure is further arranged between the vehicle arms and the vehicle body so that the vehicle arms can rotate between the horizontal position and the vertical position; springs are further connected between the vehicle arms and the vehicle body, and the springs have tensile force enabling the vehicle arms to rotate to the vertical position. According to the unmanned aerial vehicle, the unmanned aerial vehicle can pass through narrow terrains in the task execution process by shortening the length of the vehicle arms, and the voyage and the load cannot be reduced; and by rotating the vehicle arms, the size is reduced so as to facilitate transportation and transfer, and manual work and auxiliary equipment intervention operation are not needed in the rotating process of the vehicle arms.

    本发明公开了一种机臂可伸缩折叠的旋翼无人机,属于无人机领域,包括机身以及分布在机身上的多个机臂,每个机臂的翼梢处均安装有旋翼组件,机臂为具有锁紧结构的可伸缩机臂;机臂与所述机身枢转连接,机臂相对于机身转动的轴线水平,且机臂与机身之间还设置有限位结构以使机臂在水平位置与竖直位置之间可转动;其中,机臂与机身之间还连接有弹簧,弹簧具有使机臂转动到竖直位置的拉力。本发明的无人机可通过缩短机臂长度的方式在任务执行过程中通过狭小地形,并且还能够不降低航程及载荷;并且通过转动机臂从而缩小体积尺寸以便于运输转移,并且机臂的转动过程不需要人工以及辅助设备介入操作。
