The invention belongs to the technical field of folding two-wheeled vehicles, and discloses a folding joint structure of a folding bicycle and a folding electric vehicle, which comprises a first vertical pipe, and the top of the outer surface of the first vertical pipe is movably sleeved with a lower connecting piece. Through the arrangement of the movable plate, the hinge rod, the insertion block and the check ring, due to the design of the check ring, the check ring can play a role in blocking movement of the pulling plate, the situation that the pulling plate moves due to mistaken touch of an operator is avoided, and when the operator needs to disassemble and replace the whole lower connecting piece and the whole upper connecting piece, the lower connecting piece and the upper connecting piece can be disassembled and replaced by rotating the check ring; the clamping opening is aligned with the pulling plate, then the pulling plate is moved to drive the movable plate to move, then the movable plate pulls the two inserting blocks to move oppositely through the hinge rod, and therefore the inserting blocks are separated from the interior of the upper connecting piece or the interior of the lower connecting piece. Therefore, fixation between the upper connecting piece and the second vertical pipe or between the first vertical pipe and the lower connecting piece can be released.

    本发明属于折叠两轮车技术领域,且公开了折叠自行车折叠电动车的折叠关节结构,包括有:第一立管,所述第一立管外表面的顶部活动套接有下连接件。本发明通过设置活动板、铰接杆、插块和挡圈,由于挡圈的设计,使得挡圈能够对拉板的移动起到阻挡作用,避免操作人员误触使得拉板发生移动,当操作人员需要对下连接件和上连接件整体进行拆卸更换时,可以通过旋转挡圈,使得卡口与拉板对齐,然后通过移动拉板,使得拉板带动活动板发生运动,进而使得活动板通过铰接杆拉动两个插块发生相向运动,从而使得插块脱离上连接件或下连接件的内部,进而能够解除上连接件和第二立管或者第一立管和下连接件之间的固定。
