The shock-proof brake system is composed of a connecting pipe, shock-proof assemblies, rear wheels and a brake pedal, the two ends of the connecting pipe are fixedly connected with the shock-proof assemblies respectively, and the lower ends of the outer sides of the shock-proof assemblies on the two sides of the connecting pipe are rotationally connected with the rear wheels respectively; brake key joint teeth which are annularly distributed are formed in the middle of the inner side wall of the rear wheel; the shock-proof assembly is composed of a fixing shaft sleeve, a fixing screw rod, a connecting shaft seat, a shock-proof shaft seat, a shock-proof spring, a limiting pressing block and a limiting spring. Through the arrangement of the shock absorption assemblies on the two sides of the connecting pipe, under the action of the shock absorption spring between the connecting shaft base in the embedding groove and the shock absorption shaft base, the acting force transmitted by the rear wheel can be buffered to a certain extent, braking of the rear wheel can be achieved through backward inclination of the brake pedal, and compared with a traditional baby carriage rear side wheel chassis, the rear side wheel chassis has the advantages of being simple in structure and convenient to use. The braking and buffering functions are integrated, and the braking and buffering device can be well applied to the baby carriage.
本发明公开一种应用于婴儿车底架的避震刹车系统,由连接管、避震组件、后车轮、刹车踏板构成,所述连接管的两端分别固定连接有避震组件,所述连接管每侧的避震组件外侧下端分别转动连接有后车轮,所述后车轮的内侧壁中部形成有呈环形分布的刹车键接齿;所述避震组件由固定轴套、固定螺杆、连接轴座、避震轴座、避震弹簧、限位按压块、限位弹簧构成。通过连接管两侧避震组件的设置,在嵌合槽内的连接轴座与避震轴座之间的避震弹簧作用下对后车轮传递来的作用力能够起到一定的缓冲作用,后车轮的刹车可通过刹车踏板的向后倾斜实现,相较于传统的婴儿车后侧车轮底架,本发明将刹车与缓冲功能集成一体,能够很好的应用在婴儿车上。
