The invention discloses an unmanned aerial vehicle arm folding mechanism which comprises a first folding piece, a second folding piece and a movable piece connecting the first folding piece and the second folding piece, the first folding piece can rotate relative to the second folding piece, and a limiting buckle and a limiting clamping piece are arranged at the rotating connecting position of the first folding piece and the second folding piece. The limiting buckle is rotationally installed on the first folding piece through a shaft shoulder screw, the limiting clamping piece is fixedly installed on the second folding piece through a fixing screw, and when the first folding piece and the second folding piece are mutually folded, the limiting buckle and the limiting clamping piece are clamped and fixed. According to the invention, the folded arms and the aircraft body can be relatively and firmly fixed, and other parts of the arms are prevented from being damaged due to inertial impact or other physical collisions when the aircraft is transported on the ground and moved manually. In addition, the limiting buckles and the limiting clamping pieces are simple in structure, can be replaced at any time if damaged, and are low in cost and convenient to replace.

    本发明公开了一种无人机机臂折叠机构,包括:第一折叠件、第二折叠件以及连接第一折叠件和第二折叠件的活动件,第一折叠件可以相对于第二折叠件转动,在第一折叠件和第二折叠件转动连接处设有限位卡扣和限位卡片,限位卡扣通过轴肩螺钉转动安装在第一折叠件上,限位卡片通过固定螺钉固定安装在第二折叠件上,在第一折叠件和第二折叠件相互折叠时,限位卡扣和限位卡片卡接固定。本发明能够很好的将折叠起来的机臂和飞机机身相对固定牢固,防止飞机在地面运输和人工移动的状态下,因为惯性冲击,或和其他物理碰撞导致的机臂其他部分损坏。另外,限位卡扣和限位卡片结构简单,如果发生损坏,可随时更换,不仅成本低且便于更换。
