Description

Technical Field

[0001] This utility model relates to the field of digital accessories technology, and in particular to a detachable mobile phone case. Background Technology

[0002] As an essential accessory for protecting smartphones, phone cases not only effectively cushion drops and prevent scratches and wear, but also serve decorative and personalized functions, gradually becoming a necessity for users. Traditional hard phone cases are usually made of engineering plastics such as PC (polycarbonate) or ABS (acrylonitrile butadiene styrene copolymer) to improve their impact resistance. However, this design often brings new problems. When the thickness of the phone case exceeds 2 mm, its rigid structure causes the edges to fit tightly to the edges of the phone. During the process of removing the phone from the phone, users need to apply a lot of external force to pry the phone case open. This can easily lead to the edge of the phone case breaking due to uneven force, or it may scratch the phone's paint due to slipping when gripped. In fact, long-term improper force may even cause the phone frame to deform, highlighting the design contradiction between hard materials and user experience. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes a detachable mobile phone case, which can solve the problem of difficulty in removing the case from the mobile phone caused by the current use of rigid materials to increase the thickness of the case.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model provides a detachable mobile phone case, including an upper shell and a lower shell, which are combined to form a case, and the upper shell and the lower shell are detachably connected.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1-4 As shown, this embodiment provides a detachable phone case, including an upper shell 1 and a lower shell 2, which are combined to form a casing. The upper shell 1 and the lower shell 2 are detachably connected. The technical solution of this embodiment utilizes an innovative detachable connection structure between the upper and lower shells. This design overcomes the limitations of traditional unibody rigid casings that rely on elastic deformation for disassembly. Through a modular disassembly mechanism, it directly eliminates the structural jamming risk caused by increased casing thickness, cleverly solving the core pain point of difficult disassembly due to the increased thickness of rigid phone cases. Specifically, both the upper and lower shells are made of rigid materials (such as PC / ABS composite materials), each independently covering the upper and lower sides of the phone. This maintains the high impact protection of the rigid material while replacing the original method of prying the entire casing apart with a split design. Users can easily disassemble the phone case by holding the upper and lower shells separately and pulling them in opposite directions, no longer affected by the thickness of the casing, thus avoiding the disassembly resistance caused by excessive thickness of the original phone case. The phone case offers several detachable options, with the upper and lower shells securely fixed together via snap-fit ​​or magnetic connections. This modular design ensures the strength of the rigid materials while mitigating the physical resistance of disassembling a single, thick-walled shell through a modular disassembly strategy, achieving a dynamic balance between protective performance and ease of use.

[0025] Preferably, the upper housing 1 and the lower housing 2 are snap-fitted together. This snap-fit ​​mechanism allows for tool-free assembly and disassembly, balancing convenience and reliable protection. Furthermore, the snap-fit ​​structure supports modular replacement of parts of the housing; for example, only the damaged side panel needs to be replaced instead of the entire housing, without the need for specialized tools, extending the product's lifespan and reducing user maintenance costs. Specifically, the upper housing 1 includes an upper back panel 11, an upper left side panel 12, and an upper right side panel 13, all integrally formed. The lower housing 2 includes a lower back panel 21, a lower left side panel 22, and a lower right side panel 23, all integrally formed. The upper back panel 11 and lower back panel 21 are snap-fitted together, as are the upper left side panel 12 and lower left side panel 22, and the upper right side panel 13 and lower right side panel 23. By dividing the overall snap-fit ​​into three connection points, a more stable connection is achieved, preventing detachment during use.

[0026] Preferably, the lower surface of the upper back panel 11 is provided with an arc-shaped protrusion 14, and the upper surface of the lower back panel 21 is provided with an arc-shaped groove 24. The contact surfaces of the arc-shaped protrusion and the arc-shaped groove cooperate to form a "slide-release" mechanical guide path. When the user applies force to assemble the upper and lower housings, the arc-shaped protrusion gradually slides into the arc-shaped groove along the outer side of the arc-shaped groove (usually designed with a gradual slope of 15°-25°). When disassembling, the arc-shaped structure can absorb the excessive force applied by the user, avoiding hard pulling caused by the housing jamming, thereby protecting the phone from buckle breakage or housing deformation caused by excessive force.

[0027] Preferably, the upper back panel 11 is provided with a camera unit 15, and a protective frame 16 is provided around the camera unit 15. The lower back panel 21 is provided with a receiving structure 25 that matches the camera unit 15. This design achieves all-round protection of the lens area through physical isolation and structural reinforcement. The protective frame adopts a trapezoidal reinforcing rib design, which increases the scratch-resistant area compared with ordinary protruding structures. Its top bevel design (such as a 30° chamfer) guides the dispersion of impact force and avoids secondary damage during scratches. In this embodiment, the camera unit 15 covers the entire area of ​​the upper back panel, making the upper and lower shells look better together when disassembled, with a more direct and stylish appearance.

[0028] Preferably, a plurality of heat dissipation holes 17 are provided on one side of the camera unit 15. By opening heat dissipation holes, the air circulation area is increased, which reduces the surface temperature of the camera module compared to a hole-free solution. Moreover, during the use of the mobile phone, the area to the right of the camera is also a heat-concentrated area. The mobile phone case of this embodiment provides heat dissipation holes in this area, which also avoids overheating caused by long-term high-frequency use, and is especially suitable for the heat dissipation requirements of high-pixel main camera and multi-camera modules.

[0029] Preferably, the upper shell 1 and the lower shell 2 are made of PC (polycarbonate). PC has high elongation at break and toughness, enabling the shell to pass rigorous drop tests (e.g., from a height of 1.5 to 2.5 meters). It reduces weight by 40% compared to metal materials while maintaining the same level of protection, adapting to the trend of lightweight and thin design. Moreover, PC has moderate melt flow, making it suitable for high-speed injection molding processes, which can achieve one-time molding of complex structures (such as curved surfaces and snap-fit ​​microstructures), shortening the production cycle and reducing the scrap rate.

[0030] Preferably, the frame thickness of the upper housing 1 and the lower housing 2 is 2-4mm. This 2-4mm thickness range is suitable for mainstream injection molding processes, avoiding shrinkage and warping defects caused by excessively thin frames, or uneven cooling and residual internal stress problems caused by excessively thick frames. The thickness tolerance can be controlled within ±0.1mm, ensuring the assembly accuracy of precision structures such as snap-fit ​​buttons and button holes.

[0031] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
