Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone shells, in particular to a foldable mobile phone shell. Background Art

[0002] Foldable phones are an innovative smartphone design that uses foldable screen technology to achieve a larger display area while maintaining portability. Compared with traditional straight-screen phones, foldable phones offer a wider range of usage scenarios, such as multitasking and watching videos in an unfolded state, or easy carrying in a folded state. The emergence of foldable phones has greatly improved the practicality and user experience of mobile devices, and is therefore favored by more and more consumers in the market.

[0003] There are some defects in the design and function of the folding mobile phone cases currently on the market. Some folding mobile phone cases are mostly designed with an integrated installation. This design often lacks effective protection at the middle hinge during the folding and unfolding process. Since the screen and hinge of the folding mobile phone need to be folded frequently, these parts are easily damaged or worn by external forces. In addition, many existing mobile phone cases cannot adapt well to the structural changes of folding mobile phones during installation, resulting in jamming during the folding and unfolding process, affecting the user experience; while for other mobile phone cases, when the folding mobile phone is unfolded, the hinge part may be suspended without any protective measures, which not only increases the risk of damage to the hinge, but may also cause damage to the folding part of the screen.

[0004] Therefore, a foldable mobile phone case is needed to solve the above problems. Summary of the invention

[0005] The utility model aims to provide a foldable mobile phone case to solve the problem that the shaft part is not protected or the case itself is worn out due to frequent folding as mentioned in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable mobile phone case, comprising a PC lower cover, a PC upper cover and a TPU main body upper part, the upper part of the TPU main body is located above the TPU foldable upper and lower sections connected structure, and the lower part of the TPU main body is located below the TPU foldable upper and lower sections connected structure, the outer layer of the TPU foldable upper and lower sections connected structure is equipped with a PC upper cover, a TPU shaft protection belt is equipped below the PC upper cover, a PC lower cover is equipped outside the TPU shaft protection belt below the PC upper cover, a buckling structure is arranged between the PC upper cover and the TPU shaft protection belt, the buckling structure comprises three groups of buckle blocks located below the PC upper cover, the buckle blocks are distributed at equal intervals, three groups of buckle grooves corresponding to the positions of the buckle blocks are arranged above the TPU shaft protection belt, and the buckle blocks and the buckle grooves are buckled and fixed.

[0007] Furthermore, the size of the TPU shaft protection belt matches the lower part of the TPU main body, and the TPU shaft protection belt is made of transparent material.

[0008] Furthermore, the upper surface of the TPU shaft protection belt is processed with a triangular grid, and the lower surface of the TPU shaft protection belt is processed with three groups of strip-shaped through grooves.

[0009] Furthermore, the PC lower cover and the upper part of the TPU main body are coated with the same color, and the PC upper cover and the TPU shaft protection belt are components made of transparent TPU material.

[0010] Furthermore, the TPU shaft protection belt matches the size of the lower part of the TPU body, the PC cover matches the size of the upper part of the TPU body, an external screen groove is opened at the same position inside the PC cover and the upper part of the TPU body, and the position of the external screen groove coincides with that after the PC cover and the upper part of the TPU body are assembled.

[0011] Furthermore, the TPU foldable upper and lower sections of the connected structure are provided with corresponding concave and convex key grooves at the volume key position on the left side, and the PC top cover is processed with a semi-enclosed reserved groove at the volume key position.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the foldable mobile phone case not only effectively protects the hinge part of the mobile phone, avoids wear and damage caused by frequent folding, provides higher protection and convenience of use, realizes a separate assembly design, and each component can be replaced independently, but also reduces weight, ensures heat dissipation, and ensures a good feel in use;

[0013] By providing buckle blocks, buckle grooves, and TPU shaft protection belts, the PC upper cover and the TPU shaft protection belt are buckled and fixed by the buckle blocks and the buckle grooves, and then the PC lower cover and the PC upper cover are respectively installed at corresponding positions on the upper part of the TPU body and the lower part of the TPU body. Through the split connection design, the PC upper cover and the PC lower cover can more flexibly adapt to the structure of the folding mobile phone, and will not produce jamming during folding and unfolding. The buckle block and the buckle groove buckle fixing method ensure that the mobile phone case can be firmly connected during use, and is convenient for disassembly and replacement. The TPU shaft protection belt has good elasticity, can effectively protect the shaft part of the mobile phone, and avoid wear and damage caused by frequent folding. This design solves the problem of the inadaptability of traditional mobile phone cases in the application of folding mobile phones, and provides higher protection and convenience of use.

[0014] The PC lower cover, PC upper cover and TPU folding upper and lower two-section connected structure are provided, and the PC lower cover, PC upper cover and TPU folding upper and lower two-section connected structure are assembled separately. The TPU folding upper and lower two-section connected structure is composed of a TPU main body upper part and a TPU main body lower part, and a bending gap is reserved in the middle. The separate assembly design enables each component of the mobile phone case to be replaced independently. When the user needs to replace a damaged component, it is not necessary to disassemble the entire mobile phone case, but only to replace the damaged part. This not only improves the service life of the mobile phone case, but also reduces the maintenance cost of the user;

[0015] A PC top cover, a TPU main body upper part, and a TPU shaft protection belt are provided, and corresponding concave and convex key grooves are provided at the left volume button position of the upper part of the TPU main body. A semi-enclosed reserved groove is processed at the volume button position of the PC top cover, and there is no need to process the corresponding key groove on each layer, thereby reducing the overall weight. The TPU shaft protection belt is processed with a triangular grid structure at the shaft, and three groups of strip through grooves are processed on the lower half, which ensure the feel while improving the heat dissipation effect, ensuring the convenience of operating physical keys, while reducing unnecessary processing and reducing the overall weight of the mobile phone case. The triangular grid structure and strip through groove design of the TPU shaft protection belt enhance the feel of the mobile phone case. BRIEF DESCRIPTION OF THE DRAWINGS
