It is understood that, after the multi-segment folding plate 50 is unfolded, in the folding and unfolding direction of the multi-segment folding plate 50, one of the two folding portions 51 which are farthest away is the first folding portion 5101, and the other is the second folding portion 5102; with such an arrangement, the multi-section folding plate 50 can integrally rotate relative to the bearing plate 40, so that the inserting groove 101 is completely opened, and the flat car 100 can be conveniently nested and stored.

In another embodiment of the present application, as shown in fig. 2, the flat car 100 is provided with a hinge protrusion 511 in one of the side portions where the two adjacent folding portions 51 meet each other, and a hinge notch 512 in the other side portion; the hinge notch 512 is provided with a hinge column 52 therein, the hinge protrusion 511 is provided with a hinge hole therein, and the hinge column 52 is inserted into the hinge hole. After the multi-section folding plate 50 is unfolded, the hinge protrusion 511 is inserted into the hinge notch 512, so that the gap between the two folding parts 51 can be reduced, the goods can be stably placed on the unfolded multi-section folding plate 50, and the carrying requirement of the small-size goods can be met; in addition, two adjacent folding portions 51 are connected by inserting the hinge post 52 into the hinge hole, and the two adjacent folding portions 51 rotate relatively, so that the folding and unfolding of the multi-section folding plate 50 are realized; specifically, when the hinge pillar 52 is fixedly connected with the corresponding folding portion 51, the hinge pillar 52 is in clearance fit with the hinge hole, and the shell realizes relative rotation between two adjacent folding portions 51; alternatively, when the hinge pillar 52 is rotatably connected to the corresponding folding portion 51, the hinge pillar 52 is in clearance fit with the hinge hole or the hinge pillar 52 is fixed in the hinge hole, so that the relative rotation between two adjacent folding portions 51 can also be realized.

In another embodiment, the hinge structure between the first folding portion 5101 and the carrying plate 40 may be the same as or different from the hinge structure between two adjacent folding portions 51, for example, the first folding portion 5101 and the carrying plate 40 may be connected by a hinge structure such as a hinge.

Alternatively, the hinge structure between the second folded portion 5102 and the carrying plate 40 may be the same as or different from the hinge structure between two adjacent folded portions 51, for example, the second folded portion 5102 and the carrying plate 40 may be connected by a hinge structure such as a hinge.
