The invention relates to the technical field of baby carriage braking equipment, and discloses an active brake wheel set mechanism for a baby carriage. The mechanism comprises a transmission shaft, a driven plate wheel fixedly sleeves the middle part of the outer surface of the transmission shaft, and a fixed chuck movably sleeves the periphery of the driven plate wheel, a fixed plate wheel fixedly sleeves the interior of the fixed chuck and located on the periphery of the driven plate wheel, the upper end and the lower end of the outer surface of the fixed plate wheel are each provided with a set of magnetic resistance membranes, and the outer surface of the fixed plate wheel is movably sleeved with a driven sliding sleeve. According to the active brake wheel set mechanism for the baby carriage, the driven plate wheel and a transmission structure on the driven plate wheel are arranged, so that the relative rotation resistance between the driven plate wheel and the fixed plate wheel is changed by the change of whether a magnetic field is applied to magnetorheological fluid in an inner cavity of the driven plate wheel or not; and the mechanism can actively brake the baby carriage when the baby carriage stops, so that the situation that braking operation is forgotten due to negligence of manual operation, and the baby carriage slides is effectively avoided.

    本发明涉及婴儿车制动设备技术领域,且公开了一种用于婴儿车上的主动制动轮组机构,包括传动轴,传动轴外表面的中部固定套接有从动盘轮,从动盘轮的外围活动套接有固定卡盘,固定卡盘的内部且位于从动盘轮的外围固定套接有固定盘轮,固定盘轮外表面的上下两端分别设有一组阻磁膜片,固定盘轮的外表面活动套接有从动滑套。该用于婴儿车上的主动制动轮组机构,对于从动盘轮及其上传动结构的设置,以通过是否对其内腔中的磁流变液施加磁场的变化,而改变从动盘轮与固定盘轮之间的相对旋转阻力,并在该婴儿车停止时可主动对其进行制动动作,有效地避免了因人为操作的疏忽而忘记对其进行制动操作并导致其发生溜车情况的发生。
