Finally, as shown in FIG. 33 , the first belt body 221 and the second belt body 222 of the strap 220 are combined with each other to complete the storage operation of the luggage case structure 10 . In addition, comparing FIG. 33 with FIG. 25 , it can be found that the volume of the luggage structure 10 at the storage position is much smaller than the volume of the luggage structure 10 at the use position.

Please refer to FIG. 34 . FIG. 34 is a three-dimensional schematic view of the structure of the suitcase in the seventh embodiment.

The luggage case structure 10 of this embodiment includes a case back member 100 , a case shell member 200 and an annular case surface member 300 . The box back member 100 and the box shell member 200 are made of relatively hard materials, which have better protection, such as plastic sheets such as polyethylene (PE), polypropylene (PP), EVA or ABS resin (ABS) or made of cloth.

Two opposite sides of the annular box surface member 300 are respectively connected to the edge of the box back member 100 and the edge of the box shell member 200 to form an accommodating space 330 . The annular box surface member 300 has a plurality of first accommodating parts 301 , a plurality of second accommodating parts 302 , a plurality of first reinforcing pieces 910 and a plurality of second reinforcing pieces 920 . The first accommodating portions 301 are respectively located on the side edges of the box back member 100 . These second accommodating portions 302 are respectively located at the end corners of the box back member 100 . Each first accommodating portion 301 maintains a distance from each second accommodating portion 302 . The first reinforcing pieces 910 are detachably disposed on the first accommodating portions 301 respectively. The second reinforcing pieces 920 are respectively detachably disposed on the second receiving portion 302 so that a plurality of bending portions 303 are formed between the first receiving portion 301 and the second receiving portion 302 . In this embodiment, the first reinforcing piece 910 and the second reinforcing piece 920 are plates with a hardness greater than that of the first accommodating portion 301 and the second accommodating portion 302, but it is not limited thereto. In other implementations In an example, the first reinforcing piece 910 and the second reinforcing piece 920 can also be made of wire frame, wood board, plastic board, iron board, aluminum board, cardboard, rubber or magnesium-aluminum alloy board. In this embodiment, the annular box surface member 300 has a first accommodating portion 301 and a second accommodating portion 302, but it is not limited thereto. In other embodiments, the annular box surface member 300 may only have a second accommodating portion 302 An accommodating portion 301 , and the first reinforcing member 910 are detachably disposed on the first accommodating portion 301 , so that a plurality of flexure portions 303 are formed between each first accommodating portion 301 .

It is worth noting that since each accommodating portion 301 , 302 is provided with each reinforcement piece 910 , 920 , the hardness is relatively high, which can improve the effect of protecting the contents inside the luggage case structure 10 . Since each of the flexures 303 is not equipped with reinforcing pieces 910, 920, the flexible deformation capacity of each flexure 303 is greater than that of each first accommodation portion 301 and each second accommodation portion 302. flexible deformation capability. The flexible portions 303 are bendable, so that the second accommodating portions 302 can be stacked relative to each other or stand upright on the box back member 100 .

In addition, in other embodiments, the structure of the box side portion 386 and the connecting portion 387 described in FIG. 1 can also be applied to the above-mentioned first accommodating portion 301 .

In the suitcase structure disclosed above, since the annular box surface member is composed of a plurality of bending parts and a plurality of supporting parts with two different flexible deformation capabilities, and each bending part has bendability, so The user can press and fold each supporting portion inwardly and stack it on the back member of the case, so that the volume of the folded luggage structure is much smaller than that of the unfolded luggage structure, so that the luggage structure can be easily stored.

In addition, since the annular box surface member is composed of multiple flexure sections and multiple sidewall sections with two different flexible deformation capabilities, and each flexure section is bendable, the user can place each sidewall The segments are folded inward and stacked on the back member of the case, so that the volume of the folded luggage structure is much smaller than that of the unfolded luggage structure, so that the luggage structure is easy to be stored.

In addition, since the structural strength of the honeycomb panel is greater than that of the annular box surface member, the overall structural strength of the trunk structure can be increased.

Furthermore, the zipper of the suitcase structure extends with a connecting section, so the box shell member and the annular box surface member can keep a distance from each other to ensure that the box shell component will not interfere with the user’s folding of the annular box surface member.

In the suitcase structure, the connecting part of the ring-shaped box surface member is arranged in the concave part of the outer wall surface of the side part of the box or through the concave part of the side part of the box, so that the user can operate the chain piece from the outside of the suitcase when storing the suitcase structure. to join or separate chains.

Moreover, in the luggage case structure disclosed above, each flexible structure has an inclination angle. And because the flexible deformation capacity of the flexible structure is greater than the flexible deformation capacity of each side wall, and these flexible structures are bendable, so that two adjacent side wall parts can be connected with the flexible structure. The folded suitcase structure is folded and stacked relative to each other, so that the volume of the folded suitcase structure is much smaller than that of the unfolded suitcase structure, so that the suitcase structure can be easily stored.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
