The invention discloses a baby carriage wheel brake mechanism. Wheels are rotatably mounted on a wheel bracket; brake inner gear rings are coaxially and fixedly arranged on the wheels; a brake block can be mounted on the wheel bracket in a sliding manner along the radial direction of the wheels; one end of the brake block is provided with latches extending along the axial direction of the wheels;the latches are inserted into the brake inner gear rings and can be meshed and clamped with the brake inner gear rings; an elastic piece provides elastic force for keeping meshing and clamping of thelatches and the brake inner gear rings for the brake block; a brake guide rod can be mounted on the wheel bracket in a sliding manner; one end of the brake guide rod abuts against the other end of thebrake block; the brake guide rod slides to press against the brake block to overcome the elastic force of the elastic piece to radially slide along the wheels; a switch is installed on the wheel bracket and can drive the brake guide rod to slide in a reciprocating mode. The baby carriage wheel brake mechanism is simple in structure, two wheels can be braked or brake can be canceled at the same time through one switch, operation is convenient, braking is stable, and the situation of brake failure is avoided.

    本发明公开了一种婴儿车车轮刹车制动机构,车轮能转动的安装于车轮支架上,车轮上同轴固设有刹车内齿圈,刹车块能够沿车轮径向滑动的安装于车轮支架上,刹车块一端设有沿车轮轴向延伸的卡齿,所述卡齿插设于刹车内齿圈内并能够与刹车内齿圈啮合卡置,弹性件给刹车块提供保持卡齿与刹车内齿圈啮合卡置的弹性力,刹车导杆能够滑动的安装于车轮支架上,所述刹车导杆一端紧抵刹车块另一端,且刹车导杆滑动能够抵压刹车块克服弹性件弹力沿车轮径向滑动,开关安装于车轮支架上,开关能够驱动刹车导杆往复滑动,本发明结构简单,通过一个开关即可实现两个车轮同时刹车或取消刹车,操作方便,刹车稳定,避免了刹车失灵情况发生。
