[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] The utility model discloses a soft-hard combined folding storage trolley case, comprising a case body, wherein the case body is composed of a front part 2 and a rear part 1; the front part 2 and the rear part 1 together form a storage space as a main travel storage area. The rear part 1 is a rigid groove shell structure, that is, the whole is recessed inward to form a storage space, and has an opening and a peripheral edge 10 surrounding the opening. The peripheral edge 10 is used to connect with the front part 2. The rear part 1 is formed by processing a rigid material, has a stable support effect, and can be used to set a case body pull rod, etc.

[0025] The innovation of the utility model is that the front part 2 and the rear part 1 each provide a part of the accommodation space, and the front part 2 has the function of unfolding and folding, and after folding, it can pass through the opening of the rear part 1 and be accommodated in the groove structure of the rear part 1. Therefore, the front part 2 includes a rigid bottom plate part 21 and a flexible wall surface 20; the bottom plate part 21 provides rigid support for the bottom of the front part 2, so as to avoid deformation of the box body when the front part 2 is unfolded and used due to the bottom surface of the front part 2 being too soft and not rigid, thereby affecting the use effect.

[0026] In order to achieve the above-mentioned accommodation effect, the bottom plate 21 is connected to the bottom end of the rear part 1 in a bendable manner, so that the bottom plate 21 can be turned over along the connection portion between the bottom plate 21 and the rear part 1 and accommodated in the groove of the rear part; the wall surface 20 is connected to the rear part 1, and the wall surface 20 can be folded inward along the connection portion between the bottom plate 21 and the rear part 1 and accommodated in the groove of the rear part 1. When the bottom plate 21 and the wall surface 20 are turned inward relative to the rear part 1, the folding effect of the box body is achieved, that is, as shown in the attached manual Figure 3 As shown, the space occupied by the entire box is substantially equal to the overall size of the rear portion 1. When the bottom plate 21 and the wall 20 are turned outward relative to the rear portion 1, the box is unfolded. Figure 2 As shown, the space occupied by the box is equal to the sum of the rear part 1 and the unfolded front part 2.

[0027] The structure of the front part 2 and the connection between the front part 2 and the rear part 1 are further explained below. According to the above-mentioned innovations, the front part 2 should be an open pocket-shaped structure, and the structure should also have a rigid bottom. This rigid bottom is the bottom plate part 21. As a preferred technical solution, the flipping angle of the connection between the bottom plate part 21 and the rear part 1 should be maintained between 0-180°. If it exceeds 180°, when the box body is lifted, the bottom surface of the front part 2 will face downward, and it will not be on the same horizontal plane as the bottom end of the rear part 1, which will affect both the appearance and the use effect. Therefore, after the bottom plate 21 is flipped outward to the end along the connection between it and the rear part 1, it is preferably kept parallel to the bottom end of the rear part 1.

[0028] Furthermore, the bottom plate 21 and the wall 20 can be two relatively independent components, that is, the bottom plate 21 can be connected to the wall 20 and the rear portion 1 respectively. The bottom plate 21 can also be installed inside the wall 20 so that it and the wall 20 form an integrated structure.

[0029] This embodiment shows two configuration schemes of the bottom plate 21 as an independent component. Figure 1 , 4 As shown, the bottom plate 21 is an independent component, one side of which is connected to the bottom end of the rear part 1, especially to the peripheral edge 10 of the bottom end of the rear part in a bendable manner, wherein the bendable connection method includes hinge or a method equivalent to hinge, or the bottom plate 21 includes a flexible outer layer, and a rigid supporting plate is arranged inside the outer layer. The flexible outer layer is connected to the rear part 1, so that the bottom plate 21 can be bent along the connection part, as shown in the attached manual Figure 5As shown. The bottom plate portion 21 is connected to the wall 20 on all sides except one side connected to the bottom end of the rear portion 1. The wall 20 is connected to the outer peripheral edge of the rear portion 1 except for the connection portion of the outer peripheral edge of the bottom end, so that the accommodating space of the box is surrounded by the rear portion 1, the wall 20 and the bottom plate portion 21. When the box is unfolded, the bottom plate portion 21 can be seen on the outside of the bottom. In the utility model, "connection" methods other than "bendable connection" refer to conventional connection methods in the field of luggage, such as heat pressing, sewing, gluing, riveting, zippers, etc., which will not be elaborated here.

[0030] Another solution is that the wall 20 is configured to be a pocket-shaped structure, connected to the outer peripheral edge 10 of the rear portion, to form an accommodating space. The bottom plate portion 21 is provided in the accommodating space as an independent component. That is, when the box is unfolded, the bottom plate portion 21 is not visible from the outside, but is visible from the inside. One side of the bottom plate portion 21 is bendably connected to the outer peripheral edge 10 of the rear bottom end. The bendable connection method includes a hinge and a method equivalent to a hinge; or one side of the bottom plate portion 21 is not in direct contact with the outer peripheral edge 10 of the rear bottom end, but is connected to the flexible wall 20; or as described in the attached manual Figure 5 As shown, the bottom plate portion 21 includes a flexible outer layer, a rigid supporting plate is arranged inside the outer layer, the flexible outer layer is connected to the rear portion 1, and the rigid supporting plate is not directly in contact with the rear portion 1, so that the bottom plate portion 21 can be bent along the connection portion.

[0031] In some embodiments, as an improvement in the processing flow, the wall surface 20 can be set as a multi-layer structure, and the bottom plate portion 21 can be relatively fixed inside the wall surface 20 and become one with the wall surface 20. Then, the wall surface 20 with the bottom plate 21 set in a pocket-shaped structure is connected to the peripheral edge 10 of the rear part to form an accommodating space. The bottom plate 21 does not directly contact the rear part, but through the flexible wall surface 20, a bendable technical effect is achieved.

[0032] Another innovative point of the utility model is that in order to further compress the space, the roller 3 under the box body can be set to a detachable structure, specifically including: a fixing seat 31 is provided on the bottom surface of the rear part 1, and a roller 32 is detachably connected to the fixing seat 31. The front part 2 is provided with a fixing seat 31 at a corresponding position of the bottom plate, and a roller 32 is detachably connected to the fixing seat 31. The fixing seat 31 is provided with a mounting hole 310 and an external button 311, and a clamp driven to be extended and retracted by the external button 311 is provided in the mounting hole 310; the roller 32 is provided with a mounting column 321 extending into the mounting hole 310, and a clamping groove matched with the clamp is provided on the mounting column 321. The user drives the clamp to extend and retract by bending or pressing the external button 311, and disassembles the roller 32. When the box body of the utility model needs to be stored in idle, the roller 32 is disassembled, which is conducive to saving space of the entire trolley case and convenient for storage.

[0033] Another innovative point of the present invention is that the wall surface 20 is made of a flexible material. Compared with a rigid material, the wall surface is easy to be provided with a storage bag 22 that can be accessed from the outside, which is convenient for users to use.

[0034] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
