The invention discloses a folding connecting structure, a vehicle arm connecting structure and an unmanned aerial vehicle. The folding connecting structure comprises a first connecting piece and a second connecting piece; the first connecting piece comprises a first upper hole and a containing cavity formed below the first upper hole; the second connecting piece comprises a second upper hole and asecond lower hole; a pin shaft penetrates through the first upper hole and the second upper hole; the first pin penetrates through the containing cavity and the second lower hole, a spring sleeves one end, on the outer side of the first connecting piece or the second connecting piece, of the first pin and the end is connected with a button, and a second pin sleeves the other end of the first pin; and under the normal state of the spring, at least part of the periphery of the second pin is in clearance fit with the containing cavity. According to the folding connecting structure, the two connected pieces can be folded or unfolded, the folding connecting structure is used for the unmanned aerial vehicle arm, the vehicle arm can be folded downwards, the length of the unmanned aerial vehicle arm is greatly reduced, and the convenience of the unmanned aerial vehicle in the transportation process is improved; meanwhile, the safety of the unmanned aerial vehicle in the transportation process is guaranteed, and damage is avoided.

    本发明公开了一种折叠连接结构、机臂连接结构及无人机,其中折叠连接结构包括第一连接件和第二连接件,所述第一连接件包括第一上孔和其下方的容纳腔;所述第二连接件包括第二上孔和第二下孔,销轴穿过所述第一上孔和第二上孔,第一销钉穿过所述容纳腔和第二下孔,所述第一销钉一端在所述第一连接件或第二连接件外侧套设有弹簧且在该端部连接按钮,另一端外套设有第二销钉,在所述弹簧正常状态下,所述第二销钉外周至少部分与所述容纳腔间隙配合。本发明的折叠连接结构可使两被连接件折叠或伸展,用于无人机机臂可使机臂向下折叠,大幅度减少了无人机机臂的长度,增加了无人机运输过程的便利性,同时保障了无人机在运输途中的安全性,避免受损。
