The folding trailer comprises a trailer frame, a first wheel assembly and a second wheel assembly, the first wheel assembly and the second wheel assembly are arranged at the bottom of the trailer frame, the trailer frame comprises a first support, a second support and an underframe assembly, the first support and the second support extend in the vertical direction in the unfolded state, and the underframe assembly can be arranged between the first support and the second support in a folded mode in the front-back direction. A linkage mechanism used for driving the second wheel frame to rotate around a second steering shaft of the second wheel frame in a linkage mode when the bottom frame assembly is unfolded or folded in the front-back direction is further arranged between the second wheel frame of the second wheel assembly and the bottom frame assembly. Thus, in the folding process of the frame, the linkage mechanism drives the second wheel assembly used as the directional wheel assembly to turn over, so that the second wheel body of the second wheel assembly rotates, and the second wheel body of the second wheel assembly and the first wheel body of the first wheel assembly used as the universal wheel assembly are attached and folded together in the front-back direction; in this way, the structure of the folded frame is smoother and more compact, and the size and size of the folded frame are further reduced.

    本发明公开了一种折叠拖车,包括车架、设于车架底部的第一轮组件与第二轮组件,车架包括在展开状态下分别沿上下方向延伸的第一支架与第二支架、以及能够沿前后方向收折地设置在所述第一支架与所述第二支架之间的底架组件,第二轮组件的第二轮架与底架组件之间还设置有用于在所述底架组件沿前后方向打开或收折时联动驱使第二轮架绕其第二转向轴转动的联动机构。如此,车架在折叠的过程中,联动机构驱使作为定向轮组件使用的第二轮组件翻转,从而使得第二轮组件的第二轮体转动,并与作为万向轮组件的第一轮组件的第一轮体沿前后方向贴合收拢在一起,这使得折叠后的车架的结构更加的平整紧凑,进一步减小了车架折叠后的体积与尺寸。
