The invention discloses an unmanned aerial vehicle with automatic folding machine arms, and relates to the technical field of unmanned aerial vehicles, in particular to the unmanned aerial vehicle with the automatic folding machine arms, the unmanned aerial vehicle comprises a machine body shell, a folding power assembly arranged on the machine body shell and a plurality of machine arm assemblies arranged on the folding power assembly, and the folding power assembly is in transmission connection with the machine arm assemblies; a stepping motor drives a lifting flange plate to ascend and descend, the lifting flange plate pushes and presses a machine arm connecting rod when descending, the machine arm connecting rod rotates around a center shaft by a certain angle, meanwhile, the machine arm connecting rod drags and pulls a supporting rod, the supporting rod rotates around the center shaft by 90 degrees, and the supporting rod drives a machine arm carbon tube to rotate from a horizontal state to a vertical state; therefore, longitudinal folding of the arms is achieved, the purpose of automatically and longitudinally folding the arms of the unmanned aerial vehicle is achieved, automatic folding and unfolding of the arms of the multi-rotor unmanned aerial vehicle are achieved, the range of the transverse space occupied by the unmanned aerial vehicle is reduced, and the requirements of a small-size automatic airport for existence, take-off and landing of the unmanned aerial vehicle are met.

    本发明公开了一种自动折叠机臂无人机,涉及无人机技术领域,具体为一种自动折叠机臂无人机,包括机身壳体、设置在机身壳体上的折叠动力组件、设置在折叠动力组件上的多个机臂组件,所述折叠动力组件与各个机臂组件传动连接;通过步进电机驱动升降法兰盘升降移动,升降法兰盘在下降移动时推压机臂连杆,机臂连杆绕中心轴旋转一定角度,同时,机臂连杆牵引拉动支撑杆,使支撑杆绕中心轴旋转90度,支撑杆带动机臂碳管由水平状态旋转为竖直状态,从而实现机臂的纵向折叠,达到了自动化纵向折叠无人机机臂的目的,实现多旋翼无人机机臂的自动折叠收放,使无人机占用横向空间范围缩小,以满足小体积自动机场对无人机的存在、起降需要。
