A folding buggy comprises a buggy frame with an unfolding position and a folding position and a plurality of wheel assemblies arranged at the bottom of the buggy frame, the buggy frame comprises a base, a bottom wheel frame and a connecting rod, the bottom wheel frame is sleeved with the base and can take the center line of the bottom wheel frame as an overturning shaft, and the connecting rod is rotationally arranged on the base around a folding shaft. The axis of the first folding shaft is spatially perpendicular to the axis of the turnover shaft, the connecting rod is provided with a connecting rod swing section, the bottom wheel frame is provided with a fixed upper limiting part and a fixed lower limiting part, and the connecting rod swing section is located between the upper limiting part and the lower limiting part. When the frame is folded or unfolded, the swing section of the connecting rod abuts against the upper limiting part or the lower limiting part to drive the bottom wheel frame to rotate relative to the base, so that the effect that the wheel assembly extends downwards synchronously when the frame is unfolded and is folded upwards synchronously when the frame is folded is achieved, the overall design structure is simple, unfolding and folding operation is convenient, the size is small after folding, and use is convenient. And the manufacturing cost is low.

    一种折叠儿童车,包括具有展开位置与折叠位置的车架、设置于车架底部的多个轮组件,车架包括底座、与底座相套设并能够以自身中心线作为翻转轴的底轮架、绕折叠一轴转动设置于底座上的连杆,折叠一轴的轴心线与翻转轴的轴心线相空间垂直,连杆上具有连杆摆段,底轮架上具有固定的上限位部、下限位部,连杆摆段位于上限位部与下限位部之间。当车架在折叠或展开过程中,连杆摆段抵在上限位部或下限位部上,带动底轮架相对底座转动,从而实现车架展开时轮组件便同步向下伸出,而车架折叠时轮组件便同步向上收起的效果,整体设计结构简单,展开折叠操作方便,折叠后体积小,且制作成本低廉。
