DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions of the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the embodiments are merely some rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

As shown in FIG. 1 to FIG. 3, the embodiment of the present disclosure provides a foldable storage box. The foldable storage box includes a bottom plate 10, a first side plate 20, a second side plate 30, a third side plate 40, a fourth side plate 50, and a cover plate 60. The bottom plate 10 is hinged with each of the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50, respectively.

The foldable storage box has the following two states: a non-folded state and a folded state. When the foldable storage box is in the non-folded state, a cavity 70 is formed inside the foldable storage box to store items. When the foldable storage box is in the folded state, components of the foldable storage box are stacked to reduce a volume of the foldable storage box itself. When the foldable storage box is in the non-folded state, each adjacent two of the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50 are detachably connected to each other. The cover plate 60 and the bottom plate 10 are arranged facing each other. The first side plate 20 and the third side plate 40 are arranged facing each other. The second side plate 30 and the fourth side plate 50 are arranged facing each other. The bottom plate 10, the first side plate 20, the second side plate 30, the third side plate 40, the fourth side plate 50, and the cover plate 60 enclose the cavity 70 for storage. When the foldable storage box is in the folded state, the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50 each are folded on the bottom plate 10. The bottom plate 10 is arranged on the cover plate 60. In the folded state, the components in the foldable storage box are arranged sequentially from bottom to top as follows: the cover plate 60, the bottom plate 10, the fourth side plate 50, the second side plate 30, the third side plate 40, and the first side plate 20.

In a process of the foldable storage box to change from the non-folded state to the folded state, the cover plate 60 is taken off from a top of the foldable storage box. Among the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50, it changes from a connected state to a detached state between each two adjacent side plates. Because being hinged with the bottom plate 10, the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50 can rotate towards the bottom plate 10 and folded on the bottom plate 10 successively. The bottom plate 10 is then placed on the cover plate 60. In this way, the foldable storage box changes from the non-folded state to the folded state.

As shown in FIG. 4 to FIG. 15, the bottom plate 10 includes: a bottom-plate front 140 and a bottom-plate back 160. A side of the bottom plate 10 that is hinged with the first side plate 20, the second side plate 30, the third side plate 40, and the fourth side plate 50 is the bottom-plate front 140.
