[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] See also Figures 1 to 4 The core of the utility model is to provide a side-opening suitcase, comprising a case shell 1 and a case cover 5. One side of the case shell 1 is open, and the case cover 5 can be opened and closed or movably covered at the opening of the case shell 1.

[0032] The box shell 1 includes an upper shell 2, a reinforcement frame 3 and a lower shell 4. The reinforcement frame 3 is "U"-shaped. The shapes of the upper shell 2 and the lower shell 4 match the reinforcement frame 3. The reinforcement frame 3 is arranged between the upper shell 2 and the lower shell 4 and its upper and lower ends are respectively connected to the upper shell 2 and the lower shell 4. The reinforcement frame 3 is made of high-strength material and is used to support the upper shell 2 and the lower shell 4. And the reinforcement frame 3, as a supporting structure of the box shell 1, forms a box body with lateral compressive strength with the upper shell 2 and the lower shell 4.

[0033] The upper shell 2, the reinforcement frame 3 and the lower shell 4 are all made by integral molding. Specifically, the upper shell 2 and the lower shell 4 are made by vacuum integral molding, and the reinforcement frame 3 is made by injection molding.

[0034] The utility model opens one side of the box shell 1 and arranges a box cover 5 at the opening, so that the box shell 1 forms a complete structure, so that the structural strength is higher, and there is no weak point in the middle zipper like in the prior art. The box shell 1 of the utility model includes an upper shell 2, a reinforcement frame 3 and a lower shell 4. The reinforcement frame 3 is a supporting structure, supporting the upper shell 2 and the lower shell 4, so that a split design is formed, which is more flexible and convenient to manufacture and has low cost.

[0035] Specifically, the upper shell 2 and the lower shell 4 are made of vacuum integral molding, and the reinforcement frame 3 is made of injection integral molding. Vacuum molding has the advantages of small equipment investment, short mold manufacturing cycle, and fast production, but also has disadvantages such as relatively low product shape and dimensional accuracy and low structural strength. Injection molding has the advantage of high structural strength, but also has disadvantages such as large equipment investment, long mold manufacturing cycle, and slow production.

[0036] If the one-piece box shell 1 is manufactured by vacuum one-piece molding, the strength cannot meet the requirements, and if the one-piece box shell 1 is manufactured by injection one-piece molding, the cost is too high. Therefore, the box shell 1 is designed to consist of an upper shell 2, a reinforcement frame 3 and a lower shell 4, and the vacuum one-piece molding and injection one-piece molding are combined to be more economical and practical.

[0037] The reinforcing frame 3 is connected to the upper shell 2 and the lower shell 4 by gluing. Of course, other connection methods may also be used in other embodiments, such as ultrasonic welding, etc., which is not specifically limited in this embodiment.

[0038] The supporting structure of the box shell 1 includes a first frame structure, a second frame structure and a third frame structure which are arranged on the reinforcement frame 3 from top to bottom in sequence. The first frame structure, the second frame structure and the third frame structure are made into one piece, and the upper end of the first frame structure covers the lower part of the upper shell 2 to be connected to the upper shell 2, and the lower end of the third frame structure covers the upper part of the lower shell 4 to be connected to the lower shell 4. When the side of the box body is under force, the reinforcement frame 3 and the box cover 5 realize lateral support.

[0039] Specifically, a slot 6 is provided on the outer wall at the upper and lower ends of the reinforcement frame 3, respectively. The slot 6 at the upper end is open toward one end of the upper shell 2, and the slot 6 at the lower end is open toward one end of the lower shell 4. The reinforcement frame 3 is provided with a spacing flange 7 protruding outward between the two slots 6; one end of the upper shell 2 and the lower shell 4 is respectively arranged in the two slots 6 and abuts against the spacing flange 7. The slot 6 at the upper end is the first frame structure, the spacing flange 7 is the second frame structure, and the slot 6 at the lower end is the third frame structure.

[0040] Connecting the upper shell 2 and the lower shell 4 through the slot 6 not only increases the connection strength, but also makes the connection more beautiful.

[0041] The bottom of the lower shell 4 is provided with a roller 8. Specifically, the bottom of the lower shell 4 is provided with a recessed portion 9 that is recessed upward. The roller 8 is arranged in the recessed portion 9, so that the upper structure of the roller 8 is not exposed, which is more beautiful. In this embodiment, a total of four rollers 8 are provided. Of course, in other embodiments, other numbers can also be used, which is not limited in this embodiment.

[0042] A first handle 10 is provided on the top of the upper shell 2. A second handle 11 is provided on the outer side wall of the case 1. Specifically, both ends of the second handle 11 are respectively connected to the upper shell 2 and the lower shell 4. The side-opening case of the utility model can be conveniently lifted by the first handle 10 and the second handle 11, and when lifted by the second handle, the force can be evenly distributed to the upper shell 2 and the lower shell 4, and will not be concentrated on one side.

[0043] Furthermore, the box cover 5 can be connected to the box shell 1 by means of a zipper or a lock, etc., which is not specifically limited in this embodiment.

[0044] The utility model is different from the traditional luggage with a zipper in the middle. The opening of the box shell 1 is set on one side, so that the structural strength of the box shell 1 is higher, and the lateral compressive strength is provided, and no weak point of strength is formed at the zipper. At the same time, the utility model designs the box shell 1 to be composed of an upper shell 2, a reinforcement frame 3 and a lower shell 4, and adopts different molding methods to manufacture, so that the cost can be reduced while meeting the strength requirements, and it is more economical.

[0045] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
