The invention discloses a cart capable of reducing the folding height. The cart capable of reducing the folding height comprises a frame front rod, a frame rear rod, a push rod and a support rod, theframe rear rod comprises a lower rear rod and an upper rear rod arranged above the lower rear rod, the upper rear rod can slide and stretch relative to the lower rear rod in order to make the frame rear rod switched between an extension state and a contraction state, the rear end of the frame front rod is rotationally connected with the front end of the upper rear rod in order to make the frame front rod switched between a first position and a second position, and a first four-connecting-rod mechanism is in linkage with the frame front rod and the frame rear rod respectively so as to drive theframe front rod to be switched between the first position and the second position and drive the frame rear rod to be switched between the extension state and the contraction state. The cart capable of reducing the folding height is sufficient in driving force and low in overall height after being folded.

    本发明公开了一种可降低折叠高度的推车,可降低折叠高度的推车包括车架前杆,车架后杆,推杆,撑杆,车架后杆包括下后杆和设于下后杆上方的上后杆,上后杆可相对下后杆滑动伸缩以使车架后杆可在伸长状态和缩短状态之间切换,车架前杆的后端与上后杆的前端转动连接以使车架前杆可在第一位置和第二位置之间切换,第一四连杆机构分别与车架前杆和车架后杆相联动,以驱动车架前杆在第一位置和第二位置之间切换,以及驱动车架后杆在伸长状态和缩短状态之间切换。本发明的可降低折叠高度的推车驱动力足且折叠后整体高度较低。
