A child stroller comprises a stroller frame with an unfolding position and a folding position, a locking mechanism and a plurality of wheel assemblies, and the stroller frame comprises a rear wheel support, a front wheel support, a push rod frame, a rear supporting frame and a lower connecting rod. A first connecting rod mechanism is formed among the rear supporting frame, the push rod frame and the rear wheel support, a second connecting rod mechanism is formed among the rear supporting frame, the rear wheel support, the front wheel support and the lower connecting rod, the two connecting rod mechanisms share the rear supporting frame, and when the rear supporting frame rotates around three axes relative to the rear wheel support, the two connecting rod mechanisms can be controlled to operate synchronously. The push rod frame and the front wheel support synchronously get away from the rear wheel support or synchronously get close to the rear wheel support, unfolding or folding of the frame is achieved, the structure is simple, and operation is convenient.
一种儿童推车,包括具有展开位置和折叠位置的车架、锁定机构、多个轮组件,车架包括后轮支架、前轮支架、推杆架、后撑架、下连杆。在后撑架、推杆架和后轮支架之间形成第一连杆机构,在后撑架、后轮支架、前轮支架和下连杆之间形成第二连杆机构,这两个连杆机构共用后撑架,当后撑架相对后轮支架绕三轴转动的过程中,便能控制这两个连杆机构同步运作,即推杆架与前轮支架同步远离后轮支架或同步向后轮支架靠拢,实现车架的展开或折叠,结构简单,操作方便。
