The crank comprises a crank body, folding mechanisms are arranged at the two ends of the crank body correspondingly, each folding mechanism comprises a connecting base of a hollow structure and an elastic piece between the inner wall of the connecting base and the crank body, and a positioning table is fixed to the outer end of the connecting base; the positioning table is provided with a positioning groove at the outer end of the connecting seat, a positioning pin is arranged in the positioning groove in a matched mode, a positioning pin hole matched with the positioning pin is formed in the crank body, and a quick release mechanism is arranged on the side portion of the connecting seat. A folding structure formed by the connecting seats is adopted, the pedals are folded through rotation of the connecting seats, the unfolded state and the folded state of the pedals are kept through the first positioning grooves and the second positioning grooves correspondingly, the pedals are kept parallel to the bicycle body in the folded state, and the pedals are kept perpendicular to the bicycle body in the unfolded state; meanwhile, the pedal can be quickly disassembled and assembled through the quick disassembling mechanism, and more convenience can be provided for a user.
本发明公开了一种具备脚踏快拆和旋转折叠的曲柄,包括曲柄本体,曲柄本体的两端分别设有折叠机构,折叠机构包括呈空心结构的连接座,以及连接座内壁与曲柄本体之间的弹性件,连接座的外端固定有定位台,定位台在连接座的外端开设有定位槽,定位槽内匹配设有定位销,曲柄本体内开设有与定位销相匹配的定位销孔,连接座的侧部设有快拆机构。本发明采用连接座形成的折叠结构,通过连接座的转动实现脚踏的折叠,并通过第一定位槽和第二定位槽分别保持脚踏的打开与折叠状态,在处于折叠状态时,脚踏与车身主体保持平行,在处于打开状态时,脚踏与车身主体保持垂直,同时利用快拆机构实现了脚踏的快速拆装,能够为用户提供更多的方便。
