The invention relates to the technical field of baby carriages, in particular to a folding baby carriage. According to the folding baby carriage, the lower end of a push-pull rod is hinged to the upper end of a rear wheel supporting rod, a second protruding block of the rear wheel supporting rod is hinged to a front connecting hole of a seat frame, a first protruding block of the rear wheel supporting rod is hinged to the lower end of a seat connecting plate, and the upper end of the seat connecting plate is hinged to a rear connecting hole of the seat frame to form a quadrangular linkage structure. When a locking structure on the push-pull rod is unlocked and the baby carriage is folded downwards and backwards, the rear wheel supporting rod and the seat frame can be folded through the linkage structure. Meanwhile, the front wheel supporting rod is in a free state after the locking structure is unlocked, and the rear wheel supporting rod can get close to achieve folding under the action of self gravity.

    本发明涉及童车技术领域,尤其是涉及一种折叠童车。本发明一种折叠童车,通过推拉杆下端与后轮支杆上端铰接、后轮支杆的第二凸块与座框架的前连孔铰接、后轮支杆的第一凸块与座连板下端铰接、座连板上端与座框架的后连孔铰接四个位置的连接形成四边形的联动结构。当推拉杆上的锁止结构解锁后,向下向后折合时,可通过该联动结构将后轮支杆、座框架折叠;同时,前轮支杆从锁止结构解锁后为自由状态,受自身重力作用可想后轮支杆靠近实现收合。
