[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 2 and Figure 3 It is a shell structure of embodiment 1, including a shell plate 1 and a connecting support 2; a mounting groove is provided on one side of the shell plate 1, so that the shell plate 1 in the mounting groove has the ability to bend and deform, and the rest of the shell plate 1 is a rigid structure; the connecting support 2 is a profile member, and a supporting surface, a first corner structure and a second corner structure are formed on the connecting support 2. The supporting surface is an arc surface, and the first corner structure and the second corner structure are respectively located on both sides of the supporting surface. The connecting support 2 is embedded in the mounting groove of the shell plate 1, and the supporting surface is arranged facing the bottom of the mounting groove. The first corner structure and the second corner structure are both located outside the mounting groove; the shell plate 1 in the mounting groove is bent so that the bottom of the mounting groove is fitted with the supporting surface of the connecting support 2 to form a rounded structure, and the two corners of the mounting groove are respectively spliced with the first corner structure and the second corner structure, so that the connecting support 2 is clamped and fixed between the two corners of the mounting groove.

[0030] The working principle of this embodiment is as follows:

[0031] In the process of the shell plate 1 being bent through the installation groove to form a rounded corner structure, the two corner positions of the installation groove notch are spliced with the first corner structure and the second corner structure respectively, so that the connecting support 2 is clamped and fixed between the two corner positions of the installation groove notch, so that the connecting support 2 is fixed on the shell plate 1, and at the same time, the shell plate 1 is limited by the connecting support 2 to be bent to form a preset rounded corner structure; since the supporting surface of the connecting support 2 is arranged facing the bottom of the installation groove, and the supporting surface is a circular arc surface, the supporting surface of the connecting support 2 can provide support for the rounded corner part of the shell plate 1, thereby improving the structural strength of the rounded corner part of the shell plate 1; at the same time, such a structure enables the connecting support 2 to be located on the inner side of the shell plate 1, so that the outer surface of the shell plate 1 is an integrated structure, so that the outer surface of the shell plate 1 has high flatness, and there is no need to perform additional dyeing treatment on the connecting support 2, thereby reducing production costs.

[0032] like Figure 3 As shown, the connecting support member 2 is a plastic member. The connecting support member 2 includes an arc plate portion 21, a first support plate portion 22, a second support plate portion 23, a third support plate portion 24, a fourth support plate portion 25 and a fifth support plate portion 26; the arc plate portion 21 is an arc-shaped structure, and the outer peripheral surface of the arc plate portion 21 is the supporting surface; the arc plate portion 21, the first support plate portion 22, the second support plate portion 23, and the third support plate portion 24 are sequentially connected end to end to form a closed structure, and the first support plate portion 22 and the third support plate portion 24 are perpendicular to each other; one end of the fourth support plate portion 25 is connected to the connecting portion between the first support plate portion 22 and the second support plate portion 23, and the fourth support plate portion 25 is connected to the connecting portion between the first support plate portion 22 and the second support plate portion 23. The other end of the support plate portion 25 extends in a direction away from the first support plate portion 22, and the fourth support plate portion 25 is perpendicular to the first support plate portion 22, so that the first support plate portion 22 and the fourth support plate portion 25 together constitute the first corner structure; one end of the fifth support plate portion 26 is connected to the connection between the third support plate portion 24 and the second support plate portion 23, and the other end of the fifth support plate portion 26 extends in a direction away from the third support plate portion 24, and the fifth support plate portion 26 is perpendicular to the third support plate portion 24, so that the third support plate portion 24 and the fifth support plate portion 26 together constitute the second corner structure. A plurality of reinforcing ribs 27 are provided between the arc plate portion 21 and the second support plate portion 23. Through such a design, the connecting support member 2 has good structural strength and is not easily deformed, so that the structure of the shell plate 1 after bending to form a rounded structure is more stable.

[0033] like Figure 3As shown, the shell panel 1 includes a stacked exterior panel layer 11 and an interior support panel layer 12; the exterior panel layer 11 is bendable; the interior support panel layer 12 is a rigid plate, and the mounting groove is provided on the side of the interior support panel 12 facing away from the exterior panel layer 11. The mounting groove can be configured to penetrate the interior support panel layer 12, so that its bottom communicates with the exterior panel layer 11, or it can be configured to not penetrate the interior support panel layer 12, so that the portion of the interior support panel 12 forming the bottom of the mounting groove is bendable. In this embodiment, the mounting groove is configured to not penetrate the interior support panel layer 12, which ensures that the rounded corners of the shell panel 1, after being bent to form a rounded corner structure, have higher structural strength.

[0034] The number of mounting slots on the shell plate 1 ranges from 1 to 3, and the number of connecting supports 2 matches the number of mounting slots on the shell plate 1, with one connecting support 2 corresponding to one mounting slot on the shell plate 1. In actual use, the outer shell structure may be provided with different numbers of mounting slots and connecting supports 2 depending on its purpose to suit different usage scenarios.

[0035] like Figure 2 As shown, side shell panels 3 are provided on both sides of the shell panel 1. Each side shell panel 3 is arranged perpendicular to the shell panel 1 and connected to the shell panel 1 via angle connectors 4. Thus, the shell panels 1 and the two side shell panels 3 enclose an enclosed space. In actual use, the outer shell structure forms enclosed spaces of different structures according to its different uses to adapt to different usage scenarios.

[0036] Example 2

[0037] like Figure 4 The second embodiment is a storage box comprising a base 10 and two rotating bases 20. The base 10 and the rotating base 20 have the same outer shell structure as that described in the first embodiment. The difference between the base 10 and the rotating base 20 is that the base 10 includes two mounting slots and two connecting supports, while the rotating base 20 includes one mounting slot and one connecting support, so that the total number of mounting slots and the total number of connecting supports of the base 10 and the two rotating bases 20 are both four. One end of the shell plate of the two rotating bases 20 is rotatably connected to the two ends of the shell plate of the base 10, and the two rotating bases 20 rotate so that the other ends of their shell plates are spliced together, so that the enclosed spaces of the base 10 and the two rotating bases 20 are combined to form a closed storage cavity. By adopting the outer shell structure described in the first embodiment, the base 10 and the rotating base 20 have a high degree of flatness of the overall outer surface of the storage box. Moreover, since the base 10 and the rotating base 20 both adopt a modular structure, the production cost is reduced.

[0038] like Figure 4As shown, this embodiment further includes a carrying handle 30, which is rotatably mounted on the shell plate of the rotating base 20. The carrying handle 30 is used to provide a gripping portion for the user, making it convenient for the user to transfer the storage box.

[0039] like Figure 4 As shown, this embodiment further includes a locking assembly 40, which is disposed between the joints of the two rotating bases 20. The locking assembly 40 is used to lock the assembled base 10 and the rotating base 20. With this structure, the storage box can be easily locked in the assembled state.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications, combinations, and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be within the scope of the claims of the present invention.
