[0019] In order to clarify the purpose, technical means and advantages of the embodiments of the present invention, the technical means in the embodiments of the present invention will be described below clearly and completely with reference to the drawings in the embodiments of the present invention, but it is obvious that the described embodiments are only some embodiments of the present invention and do not cover all embodiments. All embodiments that a person skilled in the art can obtain based on the embodiments of the present invention without any creative work shall fall within the scope of protection of the present invention. [Example]

[0020] Example 1 As shown in Figures 1 and 2, the first embodiment of the present invention provides a foldable front-opening suitcase, which includes a first suitcase body 1 and a second suitcase body 2. The first suitcase body 1 is provided with a telescopic carry bar 3 on the back, movable casters 4 are provided at the corners of the bottom of the first suitcase body 1 and the second suitcase body 2, and foldable telescopic side walls 6 are connected between the first suitcase body 1 and the second suitcase body 2. One edge of the telescopic side wall 6 is connected to the side edge of the first suitcase body 1, and the other edge of the telescopic side wall 6 is connected to the side edge of the second suitcase body 2. The first suitcase body 1, the telescopic side walls 6, and the interior of the second suitcase body 2 jointly form a suitcase partition. The second suitcase body 2 has a front opening on the front that communicates with the suitcase partition, and a front cover 5 is provided at the front opening of the second suitcase body 2.

[0021] Each component of this embodiment will be described in detail below with reference to the drawings. The elastic side walls 6 of this embodiment can be made of cloth, leather or other flexible materials, and the elastic side walls 6 can be connected to the first suitcase body 1 and the second suitcase body 2 by sewing, respectively. The second suitcase body 2 and the front cover 5 are connected by a front cover opening and closing zipper 7. When the front cover opening and closing zipper 7 is opened, the front cover 5 can be flipped open relative to the second suitcase body 2, exposing the suitcase dividers and allowing the user to put in or take out items. Because the suitcase of this embodiment uses a front-opening + front cover structure, the interior space can be opened without the suitcase being turned over, making it convenient to put in and take out items.

[0022] As shown in Figure 3, the telescopic side walls 6 are flexible and can expand and contract. When the suitcase is not in use and needs to be stored, the telescopic side walls 6 can be contracted and folded, allowing the first suitcase body 1 and the second suitcase body 2 to be brought closer together. This significantly reduces the volume of the suitcase and saves space.

[0023] Preferably, side wall support devices can be provided inside the suitcase divider, positioned on the inside of the telescopic side wall 6. As shown in FIG. 4, when side wall support devices are provided on the inside of the two upper and lower telescopic side walls 6, each side wall support device has one support plate 8, one edge of which is invertedly connected to one edge of the telescopic side wall 6, i.e., one edge of the second suitcase body or a side edge of the first suitcase body 1. Here, a cloth cover may be provided on the outside of the support plate 8. The support plate 8 may be sewn to the telescopic side wall 6 or the side edge of the first suitcase body 1 using the cloth cover.

[0024] When the support plate 8 is inverted downward or upward onto the inner surface of the telescopic sidewall 6, the support plate 8 and the telescopic sidewall 6 can be tightly fixed together by a detachable connector. This allows the support plate 8 to be supported vertically between the first suitcase body 1 and the second suitcase body 2, restricting the contraction and folding of the telescopic sidewall 6. When it is necessary to fold the suitcase, the connector is released and the support plate 8 is inverted.

[0025] As shown in FIG. 4, in this embodiment, the connector may include a connecting sheet 9 having a button 10. The connecting sheet 9 can be connected to a side edge of the first suitcase body 1 or one edge of the telescopic side wall 6, i.e., the edge that connects to the second suitcase. The connecting sheet 9 can engage with a female button on the support plate 8 via a male button. The button can be a snap button, a magnetic button, or any of various commercially available connecting buttons.

[0026] 5, in another embodiment, the connector may be a hook and loop fastener 11. For example, the hook surface of the hook and loop fastener 11 may be sewn to the elastic sidewall 6, and the loop surface of the hook and loop fastener 11 may be sewn to the support plate 8. Of course, according to actual needs, in other embodiments, the connector may not be limited to the present embodiment, but may also be a connecting button directly connected to the support plate 8 and the elastic sidewall 6, such as various commercially available connecting buttons, cable ties, or other connecting devices.

[0027] Preferably, a support plate positioning slot for inserting the support plate 8 may be added to the inner surface of the first suitcase body 1 or the second suitcase body 2 to facilitate positioning with the support plate. If necessary, the side wall support devices may be provided on the two inner sides, left and right, of the extendable side wall 6, or may be provided on the two inner sides, top and bottom, and both inner sides, left and right, of the extendable side wall 6 at the same time.

[0028] As a further improvement to this embodiment, in order to facilitate storage and stowing of the suitcases, a folding fastening band 12 may be provided between the first suitcase body 1 and the second suitcase body 2 to fasten the first suitcase body 1 and the second suitcase body 2 close together after the telescopic side walls 6 are folded, as shown in Figures 2 and 3. One end of the folding fastening band 12 is connected to the side of the first suitcase body 1, and a first fastening button 13 is provided at the other end of the folding fastening band 12. A second fastening button 14 is provided on the side of the second suitcase body 2, and the first fastening button 13 can be engaged with the second fastening button 14.

[0029] Of course, in other embodiments, one end of the folding fixing band 12 may be connected to the side of the second suitcase body 2, and the second fixing button may be provided on the first suitcase body 1 (see FIG. 10).

[0030] Preferably, to enhance the functionality of the suitcase, a foldable cup holder 15 may be added to the back of the first suitcase body 1, a hook 16 may be provided on one side of the first suitcase body 1 and / or the second suitcase body 2, and a USB charging port 17 for connecting to a portable power source may be provided on the top or one side of the first suitcase body 1 or the second suitcase 2. [Example]

The structure is almost the same as that of the first embodiment, so there is no need to repeat the same parts here. The difference is that the side wall support device is directly attached to the inside of the telescopic side walls 6. 6, when the sidewall support device is provided inside the telescopic sidewall 6, the sidewall support device may include four support plates 19. Each support plate 19 is sewn around the inside periphery of the telescopic sidewall 6. When the telescopic sidewall 6 contracts, the telescopic sidewall 6 and the four support plates 19 flatten together. [Example]

[0032] Example 3 The third embodiment of the present invention provides a foldable front-opening suitcase, which includes a first suitcase body 1, a second suitcase body 2, a telescopic carry bar 3, movable casters 4, telescopic side walls 6, and a front cover 5. The structure is almost the same as that of the first or second embodiment, so there is no need to repeat the same description here. The difference is that the first suitcase body 1 and the second suitcase body 2 are not fastened together by a fastening bond 12, but by a fastening zipper 18.

[0033] As shown in Figure 7, a folding fastener 18 is provided between the first suitcase body 1 and the second suitcase body 2, with a first fastener tape of the folding fastener 18 connected to a side edge of the first suitcase body 1 and a second fastener tape of the folding fastener 18 connected to a side edge of the second suitcase body 2.

[0034] After the first suitcase body 1 and the second suitcase body 2 approach each other, closing the folding fastener 18 restricts the movement of the first suitcase body 1 and the second suitcase body 2, realizing the first suitcase body 1 and the second suitcase body 2 being fixed close to each other. [Example]

[0035] Example 4 The fourth embodiment of the present invention provides a foldable front-opening suitcase, which includes a first suitcase body 1, a second suitcase body 2, a telescopic carry bar 3, moving casters 4, telescopic side walls 6, and a front cover 5. The structure is almost the same as that of the first or second embodiment, so there is no need to repeat the same parts here. The only difference is that the telescopic side walls 6 are provided with an expansion zipper 20 installed around the outer surface.

[0036] As shown in FIG. 8, the first fastener tape of the expansion fastener 20 is connected to the elastic side wall 6, and the second fastener tape of the expansion fastener 20 is connected to the side edge of the first suitcase body 1 or the second suitcase body 2.

[0037] In this fourth embodiment, the expandable side wall 6 can be divided into two sections, 6a and 6b. When the expansion fastener 20 is pulled up and closed, only the section 6a of the expandable side wall 6 is exposed, and the section 6b of the expandable side wall 6 is retracted. When the expansion fastener 20 is opened, both sections 6a and 6b of the expandable side wall 6 can be expanded. This allows the internal volume of the suitcase to be increased.

[0038] As shown in FIG. 9, in order to facilitate the expansion and contraction of the sections 6a and 6b of the telescopic side wall 6, a hard ring 21, such as a steel ring, may be provided around the inner surface or interior of the telescopic side wall 6 and corresponding to the position of the first fastener tape of the expansion fastener.

[0040] As shown in Figure 10, the size of the second suitcase body 2 may be larger than that of the first suitcase body 1. After the telescopic side walls 6 are folded, the side edges of the first suitcase body 1 can be inserted into the interior of the second suitcase body 2, so that the first suitcase body 1 overlaps part of the side area of ​​the second suitcase body 2. This further reduces the volume of the suitcase when it is packed or stored. Similarly, in other embodiments, the size of the first suitcase body may be larger than that of the second suitcase body, and after the telescopic side walls are folded, the side edges of the second suitcase body can be inserted into the interior of the first suitcase body, so that the first suitcase body overlaps a portion of the side area of ​​the second suitcase body.
