The invention relates to the field of baby carriages, and discloses a folding unlocking device and a baby carriage, and the folding unlocking device comprises a first connecting joint, a second connecting joint, a third connecting joint, a first limiting tooth, a first spring, a transmission rope, a second limiting tooth, a second spring and a first transmission assembly. Through the arrangement of a rotary connecting structure of the first connecting joint, the second connecting joint and the third connecting joint, clamping locking of first limiting teeth and a first spring and elastic resetting of second limiting teeth and a second spring are combined; by means of the collaborative design that a transmission rope drives a first limiting tooth to be disengaged and a second transmission tooth is in linkage with the second limiting tooth through a first transmission assembly for unlocking, synchronous unlocking of a first connecting joint, a second connecting joint and a third connecting joint can be achieved by pulling the transmission rope once; the problems that an existing baby carriage is tedious in folding operation step and poor in linkage performance are solved.

    本申请涉及童车领域,公开了一种折叠解锁装置及童车,折叠解锁装置第一连接关节、第二连接关节、第三连接关节、第一限位齿、第一弹簧、传动绳、第二限位齿、第二弹簧以及第一传动组件。本申请通过设置第一连接关节、第二连接关节、第三连接关节的转动连接结构,结合第一限位齿与第一弹簧的卡接锁定、第二限位齿与第二弹簧的弹性复位,以及传动绳驱动第一限位齿脱离、第二传动齿通过第一传动组件联动第二限位齿解锁的协同设计,能够通过单次拉动传动绳实现第一连接关节与第二连接关节、第三连接关节的同步解锁,解决了现有童车折叠操作步骤繁琐、联动性差的问题。
