The invention discloses a folding device capable of simultaneously folding a handlebar and a front fork, the folding device comprises the handlebar, a handlebar stem, an upper folding seat, a lower folding seat, the front fork, a frame and a connecting rod, the handlebar is fixedly mounted on the handlebar stem, the handlebar stem is hinged with the upper folding seat through a hinge shaft A, the lower folding seat is arranged in the head tube of the frame, the upper end of the lower folding seat is connected with the lower end of the upper folding seat in a sleeved mode and fixed through fasteners, the lower end of the lower folding seat is hinged to the upper end of the front fork through a hinged shaft B. The connecting rod penetrates through the lower folding seat, the upper end of the connecting rod is hinged to the handlebar stem through a hinged shaft C, and the lower end of the connecting rod is hinged to the front fork through a hinged shaft D. The handlebar is pulled backwards with force during folding, wWhen the handlebar and the handlebar stem rotate around the hinged shaft A, the connecting rod applies force to the top end of the front fork to enable the front fork to rotate around the hinged shaft B so that the handlebar and the front fork are synchronously folded. The device is stable in structure, easy and convenient to operate and low in production cost.
本发明公开了一种能同时折叠车把和前叉的折叠装置,包括车把、把立、上折叠座、下折叠座、前叉、车架和连接杆,所述车把固定安装在把立上,把立通过铰轴A与上折叠座铰接,下折叠座置于车架头管内,下折叠座的上端与上折叠座的下端套接并通过紧固件固定,下折叠座的下端与前叉的上端通过铰轴B铰接,连接杆穿过下折叠座,其上端通过铰轴C与把立铰接,下端通过铰轴D与前叉铰接,折叠时用力向后拉动车把,车把及把立绕铰轴A旋转的同时连接杆向前叉顶端施力使前叉绕铰轴B旋转,从而实现车把和前叉同步折叠。本发明结构稳固,操作简便,生产成本低。
