Abstract
The invention relates to a baby stroller, which comprises a stroller frame, a front wheel assembly, a back wheel assembly, wherein the frame comprises a front support frame, a back support frame which is in right-angled intersection with the front support frame and is connected with the front support frame at the intersection area by a pivot, a seat frame which has a front part connected with the upper part of the back support frame by a pivot, and a lower push rod connected with the back part of the seat frame by a pivot. The lower end of the lower push rod is connected with the upper part of front support frame by a pivot. The frame also comprises front wheel connecting rods connected with the lower part of the front support frame by a pivot, back wheel connecting rods and bottom bars which are connected with the lower part of the back support frame by the pivot. The front part of the bottom bar is connected with the connecting rod of the front wheels by the pivot; the back part of the bottom bars is connected with the connecting rod of the back wheel by the pivot; the front wheel assembly is arranged at the lower end of the front wheel connecting rods; and the back wheel assembly is arranged at the lower part of the back wheel connecting rods. During folding, the distance between the lower part of the front support frame and the lower part of the back support frame is increased, and the front wheel assembly and the back wheel assembly can be folded relative to the frame under the action of the bottom bar, thereby realizing a small volume of the baby stroller after being folded.
