The invention relates to a folding cart which comprises a cart frame with an unfolded state and a folded state, a front wheel assembly and a rear wheel assembly, the front wheel assembly and the rear wheel assembly are arranged at the bottom of the cart frame, and the cart frame at least comprises a front support, a rear support and a push rod frame which extend in the vertical direction in the unfolded state. The front support comprises two front supporting rods which are arranged on the left side and the right side respectively and extend in the vertical direction, the bottom of each front supporting rod is provided with a set of front wheel assemblies, and in the process that the frame is converted from the unfolded state to the folded state, the front support, the rear support and the push rod frame are folded in the front-back direction. The width of the rear support and the width of the push rod frame in the left-right direction are constant, the lower portions of the front supporting rods on the two sides are close to each other in the left-right direction, so that the distance between the two front wheel assemblies is reduced, and meanwhile the width of the front support in the left-right direction is reduced. The width of the folded rear frame in the left-right direction mainly depends on the width of the rear support and the width of the push rod frame.

    本发明涉及一种折叠推车,包括具有展开状态与折叠状态的车架、设于所述车架底部的前轮组件与后轮组件,所述车架至少包括在展开状态下各自沿上下方向延伸的前支架、后支架及推杆架,所述前支架包括分设于左右两侧且均沿上下方向延伸的两根前支杆,每根所述前支杆的底部均设有一组所述的前轮组件,所述车架由展开状态向折叠状态转换的过程中,所述前支架、所述后支架及所述推杆架沿前后方向收拢,所述后支架与所述推杆架沿左右方向的宽度恒定,两侧所述前支杆的下部沿左右方向靠近,使得两组所述前轮组件之间的距离减小,同时所述前支架沿左右方向的宽度减小,折叠后车架沿左右方向的宽度主要取决于所述后支架与所述推杆架的宽度。
