The invention relates to a baby carriage capable of automatically orienting wheels after reversing. The baby carriage comprises a push handle assembly, a front foot assembly, a rear foot assembly and a reversing joint assembly, the push handle assembly comprises a push handle pipe, a hand brake assembly and a reversing unlocking assembly. The front foot assembly comprises a front foot supporting assembly and a front wheel assembly located at the lower end of the front foot supporting assembly. The rear foot assembly comprises a rear foot supporting assembly and a rear wheel assembly located at the lower end of the rear foot supporting assembly. The reversing joint assembly mainly comprises a front foot joint, a rear foot joint and a push handle joint which are fixedly connected with the front foot assembly, the rear foot assembly and the push handle assembly respectively and are pivoted to the central shaft in a stacked mode. The front wheel and the rear wheel are universal wheels, a brake mechanism controlled by the hand brake assembly is further arranged on the rear wheel, and the reversing joint assembly is provided with an original part linked with the universal wheel orientation mechanism. The locking state of the reversing joint can be changed by operating the reversing unlocking assembly, and at the moment, the orientation state of the front and rear wheels can be automatically changed by continuously rotating the push handle assembly. The front wheel and the rear wheel are universal wheels, the brake mechanism is independent, the brake mode is a hand brake, and instant brake can be guaranteed under any condition; when the reversing joint assembly is locked, the wheels on the same side as the push handle are oriented, and the driving stability is high; when the push handle rotates to be approximately perpendicular to the ground, orientation of the wheels on the two sides is relieved, a user can operate the baby carriage with one hand to complete the pivot steering action, and after the push handle completes steering, the wheels can be automatically oriented accordingly.

    本发明涉及一种换向后轮子自动定向的儿童手推车,它包括推把组件、前脚组件、后脚组件和换向关节组件;推把组件包含推把管、手刹组件和换向解锁组件;前脚组件包含前脚支撑组件及位于其下端的前轮组件;后脚组件包含后脚支撑组件及位于其下端的后轮组件;换向关节组件主要包括前脚关节、后脚关节、推把关节,三者分别与前脚组件、后脚组件及推把组件固定连接且于中心轴层叠枢接。所诉前后轮均为万向轮,且后轮上还设有受手刹组件控制的刹车机构,换向关节组件设有与万向轮定向机构联动的原件;操作换向解锁组件能够改变换向关节的锁定状态,此时继续转动推把组件即可自动变换前后轮的定向状态。本发明前后轮皆为万向轮,刹车机构独立且刹车方式为手刹,可保证任意情况即时刹车;当换向关节组件锁定时,与推把同侧的轮子定向,行驶稳定性高;当推把转动至接近垂直于地面状态时,两侧轮子均解除定向,使用者可单手操作儿童手推车完成原地转向动作,推把完成换向后,轮子能够随之自动定向。
