The invention discloses an unmanned aerial vehicle arm folding structure. The structure comprises an arm connecting piece arranged at one end of an arm; a main body connecting piece hinged with the arm connecting piece; a springback component arranged between the arm connecting piece and the main body connecting piece; when the other end of the arm bears a first external force applied to the arm, the arm connecting piece rotates to a folded state around the hinged position of the arm connecting piece and the main body connecting piece relative to the main body connecting piece; in the folding state, a first set angle is formed between the arm connecting piece and the main body connecting piece; and when the first external force disappears, the arm connecting piece is subjected to the pulling force of the springback component, so that the self-folding state between the arm connecting piece and the main body connecting piece is recovered to the first initial state. By means of the structure, the unmanned aerial vehicle arm has the automatic unfolding function after being folded, and the unmanned aerial vehicle is convenient to take and place. The overall structure is simple, so that the overall size of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle can be quickly put into production and applied to an unmanned aerial vehicle dense group scene.

    本申请公开了一种无人机机臂折叠结构,包括:设于机臂的一端的机臂连接件;与机臂连接件铰接的主体连接件;设于机臂连接件和主体连接件之间的回弹部件;当机臂另一端承受施加于其上的第一外力,使得机臂连接件相对于主体连接件围绕两者铰接处旋转至折叠状态;折叠状态时,机臂连接件和主体连接件之间形成第一设定角度;当第一外力消失时,机臂连接件受回弹部件的拉力,使得机臂连接件和主体连接件之间自折叠状态恢复至第一初始状态。以上结构使得无人机机臂具有折叠后的自动展开功能,方便了无人机的拿取和放置。由于整体结构较为简单,因此有利于减小无人机的整体尺寸,快速投入生产,并应用于无人机密集群场景。
