The invention discloses a baby stroller structure capable of being automatically folded by means of gravity, which comprises a stroller frame, a first four-bar mechanism and a second four-bar mechanism are arranged on the stroller frame, and the first four-bar mechanism and the second four-bar mechanism are in transmission connection through a linkage rod. The folding action can be conveniently completed through linkage of the first four-connecting-rod mechanism and the second four-connecting-rod mechanism, and operation is convenient. In the process that the frame is unlocked and folded, an operator only needs to press and turn over the upper push rod frame forwards and downwards with one hand, under the self-weight action of the upper push rod frame, the lower push rod, the push rod supporting rod and other components, the frame is folded and folded without assistance of a spring, and the mutually closed frames can stand in situ and cannot turn over after being folded, so that the folding efficiency is greatly improved. The folding chair is good in use experience, convenient to operate, small in folding size and convenient to transport.

    本发明公开了一种依靠重力实现自动折叠的婴儿推车结构,包括有车架,车架上设置有四连杆机构一和四连杆机构二,四连杆机构一与四连杆机构二之间通过联动杆传动连接,当车架进行解锁进行折叠时,便于通过四连杆机构一和四连杆机构二联动完成折叠收合动作,操作方便。车架解锁进行折叠收合过程中,操作者只需单手将上推杆架向前下压翻转,并在上推杆架、下推杆和推杆撑杆等部件的自重作用下,完成车架折叠收合,无需借助弹簧进行辅助收合,折叠后相互靠拢的车架会站立在原地,不会翻倒,本申请具有较好的使用体验,操作便利,折叠尺寸小方便运输。
