The invention discloses a rotor unmanned aerial vehicle arm folding mechanism which comprises a fixed seat, a plurality of arc-shaped sliding rails located in the longitudinal direction are evenly arranged on the fixed seat in the circumferential direction at intervals, the outer side of each sliding rail is in sliding fit with a lug rotationally connected with the fixed seat, and a torsional spring is connected between each lug and the fixed seat; the ends, away from the sliding rails, of the lug seats are fixedly connected with hollow machine arms, and locking mechanisms capable of being fixed to the sliding rails are arranged in the machine arms. According to the rotor unmanned aerial vehicle arm folding mechanism, the vehicle arms can rotate in the vertical direction along the sliding rails, so that the folding effect is achieved, occupied horizontal space is reduced, the structure is compact after the vehicle arms are folded, and storage and transportation of an unmanned aerial vehicle are facilitated. External constraint on the arms is removed, potential energy of the torsional spring is released to drive the arms to be horizontally unfolded, the arms are locked by the locking mechanism, use is convenient, and reliability is high.

    本发明公开的旋翼无人机机臂折叠机构,包括固定座,固定座上沿周向均匀间隔设置有多个位于纵向上的弧形滑轨,每个滑轨外侧均滑动配合有与固定座转动连接的耳座,耳座与固定座之间连接有扭簧,耳座远离滑轨的一端固定连接有中空的机臂,机臂内设置有可与滑轨固定的锁定机构。本发明的旋翼无人机机臂折叠机构,机臂可沿滑轨向竖直方向转动,从而实现折叠效果,减少了水平空间的占据,机臂折叠后结构紧凑,有利于无人机的存储和运输。使用时机臂所受外部约束移除,扭簧势能释放驱动机臂水平展开,锁定机构锁定机臂,使用便捷、可靠性高。
