A power assembly (10), comprising a propeller (13), the propeller (13) comprising a hub (131) and blades (136), the blades (136) being rotatably connected to the hub (131); the propeller driving device (11) is fixedly connected with the propeller hub (131) and used for driving the propeller hub (131) to rotate, and the rotating direction of the propeller hub (131) is perpendicular to the rotating direction of the propeller blades (136) relative to the propeller hub (131); the elastic pieces (16 and 16a) are connected between the propeller hub (131) and the propeller blades (136) and comprise first connecting ends (161) and second connecting ends (163) which are opposite, the first connecting ends (161) are connected with the propeller blades (136), the second connecting ends (163) are connected with the propeller hub (131), and the elastic pieces (16 and 16a) can enable the propeller blades (136) to be kept in an unfolded state; the blade tray (15) is arranged at the joint of the propeller driving device (11) and the propeller (13), and the blade tray (15) can move back and forth in the axial direction of the blade tray (15) so as to restrain the elastic force of the elastic pieces (16 and 16a) to enable the blades (136) to be folded and/or release the elastic force of the elastic pieces (16 and 16a) to enable the blades (136) to be unfolded. The propeller can be unfolded when being used and folded when not being used through back-and-forth movement of the paddle tray (15) in the axial direction of the paddle tray (15), and therefore the power assembly can be conveniently stored and placed, and then the unmanned aerial vehicle with the power assembly can be conveniently stored and placed. In addition, the invention further relates to a vehicle arm assembly, a vehicle arm connecting piece and an unmanned aerial vehicle.
一种动力组件(10),包括螺旋桨(13),螺旋桨(13)包括桨毂(131)及桨叶(136),桨叶(136)与桨毂(131)可转动地连接;螺旋桨驱动装置(11),与桨毂(131)固定连接,用于驱动桨毂(131)旋转,桨毂(131)的转动方向与桨叶(136)相对于桨毂(131)的转动方向相互垂直;弹性件(16、16a),连接在桨毂(131)与桨叶(136)之间,包括相对的第一连接端(161)及第二连接端(163),第一连接端(161)与桨叶(136)连接,第二连接端(163)与桨毂(131)连接,弹性件(16、16a)能够使桨叶(136)保持展开状态;及桨叶托盘(15),设置在螺旋桨驱动装置(11)与螺旋桨(13)的连接处,桨叶托盘(15)可沿其轴向来回移动,以抑制弹性件(16、16a)的弹力使桨叶(136)收拢和/或释放弹性件(16、16a)的弹力使桨叶(136)展开。本公开通过桨叶托盘(15)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。另外,还涉及一种机臂组件,机臂连接件及无人机。
