[0024] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0025] Embodiment:

[0026] In this embodiment, referring to the attached drawings of the specification Figures 1-4 , a luggage case body is provided, which includes a panel 1, a side frame 2 and a rear cover connection frame 3 formed by integral stretching.

[0027] Among them, the side frame 2 includes a top plate 21 and a bottom plate 23 arranged oppositely, and a first side plate 22 and a second side plate 24 arranged oppositely. The top plate 21, the first side plate 22, the bottom plate 23 and the second side plate 24 enclose a receiving cavity with a receiving function; the panel 1 is arranged on one side of the side frame 2; the rear cover connection frame 3 is connected to the side of the side frame 2 away from the panel 1, and the rear cover connection frame 3 extends outward along the circumference of the side frame 2.

[0028] The side frame 2 is a structure of an approximately rectangular parallelepiped with openings on both sides formed by the top plate 21, the first side plate 22, the bottom plate 23 and the second side plate 24. The panel 1 can be an approximately rectangular plate, and the four sides of the panel 1 are respectively connected to one side of the top plate 21, the first side plate 22, the bottom plate 23 and the second side plate 24. Thus, the panel 1 and the side frame 2 enclose a nearly rectangular parallelepiped structure with an opening on one side. A rear cover connection frame 3 is arranged to extend outward along the opening on the side of the opening of this rectangular parallelepiped structure. The rear cover connection frame 3 is used to accommodate the rear cover. When assembling the luggage case, the rear cover is arranged in the rear cover connection frame 3, and the rear cover is connected to the luggage case body through a connecting piece.

[0029] In an alternative embodiment, an installation part 11 can be arranged on the panel 1. The installation part 11 can be used to connect the front cover when assembling the luggage case. The installation part 11 can include a concave platform structure 12 formed by the panel 1 extending towards the side frame 2. The concave platform structure 12 is provided with installation holes, and a hollow part 13 can be arranged on the concave platform structure 12. Thus, through the settings of the concave platform structure 12, the hollow part 13 and the installation holes, the front cover can be accommodated in the concave platform structure 12 and the hollow part 13. On the one hand, the setting of the concave platform structure 12 can facilitate the positioning of the front cover when assembling the luggage case. On the other hand, it can make the installed front cover and the panel on the same horizontal line or the installed front cover lower than the panel, so that there is no protruding part on the external line of the luggage case product, which is convenient for the movement and placement of the luggage case product, and further improves the applicability of the luggage case product.

[0030] In an alternative embodiment, the connections between the panel 1 and the top plate 21, the first side plate 22, the bottom plate 23, and the second side plate 24 all adopt smooth transitions; smooth transitions are also adopted between the top plate 21 and the first side plate 22, between the first side plate 22 and the bottom plate 23, between the bottom plate 23 and the second side plate 24, and between the second side plate 24 and the top plate 21. Thus, smooth transitions are adopted at the corners of the luggage case shell with an approximate cuboid structure. On the one hand, the difficulty of integral stretch forming is reduced and the production efficiency is improved. On the other hand, the smooth transitions at the corners can further improve the impact resistance of the luggage case shell and enhance the product quality.

[0031] In an alternative embodiment, the rear cover connection frame 3 may include a first edge portion 31 and a second edge portion 32. The first edge portion 31 extends outward along the circumference of the side frame 2. One side of the first edge portion 31 is connected to the side frame 2, and the other side of the first edge portion 31 is connected to the second edge portion 32. The first edge portion 31 is arranged parallel to the panel 1, the second edge is arranged perpendicular to the first edge portion 31, and the first edge portion 31 and the second edge portion 32 enclose a receiving cavity capable of accommodating the rear cover. Thus, the rear cover can be received in the receiving cavity enclosed by the first edge portion 31 and the second edge portion 32.

[0032] For the receiving cavity enclosed by the first edge portion 31 and the second edge portion 32 and capable of accommodating the rear cover, the area of its cross-section parallel to the panel 1 should be larger than the maximum cross-sectional area of the side frame 2 parallel to the panel 1. Thus, on the one hand, the rear cover can achieve the effect of completely closing the receiving cavity enclosed by the panel 1, the side frame 2, and the front cover. On the other hand, the rear cover will neither occupy the storage space of the luggage nor have an excessive protruding part compared with the luggage case shell. At the same time, when the user closes the rear cover of the luggage product during use, the first edge portion 31 and the second edge portion 32 can play a limiting role, making the closing of the luggage product more convenient.

[0033] In an alternative embodiment, the rear cover connection frame 3 may further include a connecting portion 33. The connecting portion 33 is arranged on the rear cover connection frame 3 and is used to connect to one end of the rear cover. The connecting portion 33 may be arranged on the rear cover connection frame 3 corresponding to the bottom plate 23.

[0034] Specifically, a first opening is provided on the rear cover connection frame 3 corresponding to the bottom plate 23. The first edge blocking part 31 and the second edge blocking part 32 are not provided at the first opening. The connecting part 33 includes a second opening, a first annular accommodating structure and a third annular accommodating structure. Among them, the second opening is provided at the central position of the first opening. The size of the second opening is smaller than that of the first opening. The first annular accommodating structure and the third annular accommodating structure are respectively provided on both sides of the second opening. A second annular accommodating structure is provided at the position of the rear cover corresponding to the second opening. The size of the second annular accommodating structure is matched with that of the second opening. When assembling the luggage product, the second annular accommodating structure is placed in the second opening between the first annular accommodating structure and the third annular accommodating structure. At this time, the centers of the first annular accommodating structure, the second annular accommodating structure and the third annular accommodating structure are on the same straight line. A rod-shaped structure with a length greater than the axial dimension of the second annular accommodating structure is sequentially passed through the first annular accommodating structure, the second annular accommodating structure and the third annular accommodating structure, and the openable connection between the rear cover and the luggage shell can be realized. The first annular accommodating structure and the third annular accommodating structure can be unclosed annular structures. Thus, the first annular accommodating structure and the third annular accommodating structure can be integrally drawn and formed from the material together with the panel 1, the side frame 2 and the rear cover connection frame 3.

[0035] In an alternative embodiment, the luggage shell is integrally drawn and formed from a metal material. Specifically, the luggage shell can be integrally drawn and formed from an aluminum material.

[0036] Refer to the attached Figures 5-7 The embodiment of the present invention also provides a luggage, which includes a luggage shell 101, a front cover 102 and a rear cover 103. The front cover 102 and the rear cover 103 are respectively connected to the luggage shell 101. The luggage shell 101 is the luggage shell provided in any one of the above.

[0037] The luggage shell provided by the present invention and the luggage using the same replace the conventional die-casting mold manufacturing process. Through integral drawing and forming, the luggage shell has good rigidity and toughness, greatly enhancing the impact resistance and durability strength of the luggage shell. The structure of the luggage shell is more stable, improving the safety of the luggage shell and the luggage, making the appearance more flat and beautiful, reducing the use and manufacturing of die-casting molds, and lowering the production cost.

[0038] The above are only alternative embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
