The invention relates to the technical field of mother and baby products, and discloses a baby stroller with a backward sliding prevention function. The inner wall of a shell is fixedly connected with a fixing assembly, the front face of the fixing assembly is fixedly connected with wheels, the inner wall of the shell is fixedly connected with a control assembly, the inner wall of a rotating shaft is fixedly connected with an electromagnet, the outer side of the rotating shaft is movably connected with a magnetostrictive rod, the top of the magnetostrictive rod is fixedly connected with a clamping block, and the left side of the clamping block is fixedly connected with a first spring fixedly connected with the outer side of the rotating shaft. According to the baby stroller with the backward sliding prevention function, the stroller is pushed to a slope, a gravity ball slides downwards under the influence of gravity to drive an extrusion rod, the extrusion rod drives a dielectric plate to operate, the relative area between a positive plate and a negative plate is changed to generate current, an electromagnet is powered on through the current, the electromagnet generates a magnetic field to drive the magnetostrictive rod to extend, when the wheels slide backwards, clamping blocks can be clamped in grooves corresponding to fixing sleeves, and therefore the effect of preventing the trolley from sliding backwards is achieved.

    本发明涉及母婴用品技术领域,且公开了一种具有防后溜功能的婴儿手推车,所述壳体内壁固定连接有固定组件,固定组件的正面固定连接有车轮,壳体的内壁固定连接有控制组件,转轴的内壁固定连接有电磁铁,转轴的外侧活动连接有磁致伸缩杆,磁致伸缩杆的顶部固定连接有卡块,卡块的左侧固定连接有与转轴的外侧固定连接的弹簧一。该具有防后溜功能的婴儿手推车将手推车推上斜坡,重力球在重力的影响下向下滑动带动挤压杆,挤压杆带动电介质板运行,改变正极板和负极板之间的相对面积产生电流,电流对电磁铁进行通电,电磁铁产生磁场带动磁致伸缩杆伸长,当车轮向后溜时可以使得卡块被卡在固定套对应的凹槽中,从而达到了防止手推车后溜的效果。
