The device and unit for carrying the children are further provided with a stool which is hinged to the vehicle frame through a hinged stool connecting rod. The vehicle frame comprises a first vehicle frame body and a second vehicle frame body which are hinged to each other. The sitting and lying unit body is formed by sequentially hinging one end of the first seat support, a seat left inner connecting rod, a seat left outer connecting rod and one end of the second seat support together through a first seat shaft, a second seat shaft, a third seat shaft and a fourth seat shaft and sequentially hinging the other end of the first seat support, a seat right inner connecting rod, a seat right outer connecting rod and the other end of the second seat support together through a fifth seat shaft, a sixth seat shaft, a seventh seat shaft and an eighth seat shaft. The first seat support and the second seat support can rotate relative to the seat left inner connecting rod, the seat left outer connecting rod, the seat right inner connecting rod and the seat right outer connecting rod within the range of 0-360 degrees.

The invention relates to multi-suspension equipment for carrying a child, and devices, in particular to a foldable infant stroller. The multi-suspension equipment comprises a frame, wheels mounted on the frame and the sitting-lying device for an infant to sit and lie. The sitting-lying device is provided with the limiting device which can limit a first seat bracket and a second seat bracket to rotate oppositely when the first seat bracket and the second seat bracket rotate in a plane. The two sides of the sitting-lying device are hinged to the frame through at least two sets of connecting rod assemblies. The frame comprises a first frame body and a second frame body which are hinged together. The sitting-lying device is hinged by one end of the first seat bracket, a seat left inner connecting rod, a seat left outer connecting rod and one end of the second seat bracket in sequence through a first seat shaft, a second seat shaft, a third seat shaft and a fourth seat shaft, and the sitting-lying device is hinged by the other end of the first seat bracket, a seat right inner connecting rod, a seat right outer connecting rod and the other end of the second seat bracket in sequence through a fifth seat shaft, a sixth seat shaft, a seventh seat shaft and an eighth seat shaft. The first seat bracket and the second seat bracket can rotate within the range of 0-360 degrees relative to the seat left inner connecting rod, the seat left outer connecting rod, the seat right inner connecting rod and the seat right outer connecting rod.
