Abstract

A baby go-cart comprises a go-cart stander, a front wheel member and a back wheel member, wherein, the go-cart stander comprises a front support frame, a back support frame pivoted with the front support frame crisscross, a seat frame with the front portion pivoted with the upside of the back support frame and a lower push pole pivoted with the back part of the seat frame. The lower end of the lower push pole is pivoted with the upside of the front support frame. The go-cart stander also comprises a front wheel connection rod pivoted with the downside of the front support fame, a back wheel connection rod pivoted with the downside of the back support frame and a bottom rod with front part pivoted with the front wheel connection rod. The back portion of the bottom rod is pivoted with the back wheel connection rod. The front wheel member is arranged on the lower end of the front wheel connection rod. The back wheel member is arranged on the lower end of the back wheel connection rod. The distance between the downside of the front support frame and the back support frame is elongated in folding state. With the bottom rod, the front wheel member contracts with the back wheel member in contrast with the go-cart stander, thereby reducing the occupying space of the baby go-cart after folding.
