The invention relates to a quick folding mechanism for connecting an arm and an empennage of an unmanned aerial vehicle, which is characterized in that an arm end connecting pipe and an empennage end connecting pipe are respectively connected with an arm end carbon pipe and an empennage end carbon pipe through arranged crescent nuts and sunk screws, and the lower ends of the arm end connecting pipe and the empennage end connecting pipe are rotationally connected through a rotating shaft; elastic pieces are symmetrically installed on the two sides of the upper end of the arm end connecting pipe, elastic piece locking holes are formed in the ends of the elastic pieces, pop-up buttons are symmetrically installed on the two sides of the upper end of the empennage end connecting pipe through springs, locking bosses are arranged at the front ends of the pop-up buttons, and the locking bosses are matched with the elastic piece locking holes to achieve locking connection of the arm end carbon pipe and the empennage end carbon pipe. The design is scientific and reasonable, the double-elastic-piece structure is simple, operation and assembly are convenient, no complex mechanical structure exists, and clamping cannot be caused; a rotating damper of a stainless steel gasket is arranged between the double-button structure and the rotating shaft of the arm end connecting pipe and the empennage end connecting pipe, and the empennage is prevented from touching the ground through double insurance.
本发明涉及一种用于无人机机臂与尾翼连接的快速折叠机构,机臂端连接管及尾翼端连接管通过设置的月牙螺母及沉头螺钉分别连接机臂端碳管及尾翼端碳管,机臂端连接管及尾翼端连接管的下端通过旋转轴转动连接,机臂端连接管上端两侧对称安装有弹片,弹片端部设置有弹片锁紧孔,尾翼端连接管上端两侧通过弹簧对称安装有弹出按钮,弹出按钮前端设置有锁紧凸台,锁紧凸台与弹片锁紧孔配合实现机臂端碳管与尾翼端碳管的锁紧连接。本发明设计科学合理,采用双弹片结构简单,便于操作,便于组装,无繁琐机械结构不会导致卡顿;双按钮结构及机臂端连接管及尾翼端连接管的旋转轴之间设置有不锈钢垫片的旋转阻尼,双重保险避免尾翼触地。
