A bottom plate serves as a supporting body of the chassis mechanism, the lower end of an armrest frame is connected with the chassis mechanism in a fastened mode, a left front wheel is of a universalwheel structure and forms independent suspension through a left front leg rod, a fourth lower connecting rod, a fourth upper connecting rod and a fourth elastic rod, and a right front wheel is of a universal wheel structure. The left rear wheel is provided with a brake mechanism and forms independent suspension through a left rear leg rod, a first lower connecting rod, a first upper connecting rodand a first elastic rod, and the right rear wheel is provided with a brake mechanism and forms independent suspension through a right rear leg rod, a second lower connecting rod, a second upper connecting rod and a second elastic rod. The four wheels are independently suspended, so that the shock absorption performance and the passing performance of the chassis mechanism are improved, a more comfortable riding environment is provided for infants, and parents can control the baby carriage more easily.
