The invention provides a power assembly, a vehicle arm assembly, a vehicle arm connecting piece and an unmanned aerial vehicle. The power assembly comprises a propeller driving device, a propeller connected with the propeller driving device; and a paddle tray which is arranged at the joint of the propeller driving device and the propeller. The paddle tray can move back and forth in the axial direction of the paddle tray so as to allow the propeller to be folded and/or unfolded, and the propeller driving device is used for driving the propeller to rotate when the paddle tray moves to allow the propeller to be unfolded. According to the invention, the propeller can be unfolded when in use and folded when not in use through the back-and-forth movement of the paddle tray in the axial direction of the paddle tray, so that the power assembly is convenient to store and place, and the unmanned aerial vehicle with the power assembly is convenient to store and place.

    本申请提供一种动力组件,机臂组件,机臂连接件及无人机,该动力组件包括螺旋桨驱动装置;与螺旋桨驱动装置连接的螺旋桨;以及设置在螺旋桨驱动装置与螺旋桨的连接处的桨叶托盘,桨叶托盘可沿其轴向来回移动,以允许螺旋桨收拢和/或展开,螺旋桨驱动装置用于在桨叶托盘移动至允许螺旋桨展开时驱动螺旋桨旋转。本申请通过桨叶托盘沿其轴向的来回移动能够使得螺旋桨在使用时展开,而在不使用时收拢,从而方便动力组件的收纳放置,进而方便具有该动力组件的无人机的收纳放置。
