[0036] Foldable phones are smart devices that utilize flexible screens and special hinge designs. They achieve form factor transformation through the foldable nature of the screen, balancing a large-screen experience with portability. The core technology lies in flexible display technology; the screen material has bendable properties, and combined with a precision mechanical structure, it achieves smooth folding. Common forms include horizontal inward folding, outward folding, or vertical folding. When unfolded, they provide a display area close to that of a tablet, while folding reduces their size for easy carrying. These phones typically feature multi-angle hovering capabilities to fully leverage the advantages of folding. Due to their structural complexity, their weight and thickness are generally higher than traditional candybar phones. Screen creases and durability still require technological breakthroughs. However, the foldable form factor brings entirely new usage scenarios, such as multimedia entertainment and multitasking in the unfolded state, and one-handed operation in the folded state, becoming an important direction for exploring the boundaries of mobile device form factors.
[0037] Phone cases are a popular accessory for protecting mobile phones. Common materials include silicone, rubber, metal, and plastic. These cases are worn around the phone to provide protection against drops and scratches. With the rise of foldable phones, most cases now feature a split design. These cases consist of two independent parts that cover the back panel and the front screen of the foldable phone, respectively, to prevent interference with the unfolding of the inner screen.
[0038] However, for foldable phones, separate phone cases have several drawbacks. First, since separate phone cases are two independent parts, one or even both parts of the case can easily detach from the phone under external force, thus losing its protective function. Second, in addition to the above, separate phone cases do not provide sufficient overall coverage of the phone; for example, the hinge and other structures of foldable phones are still exposed.
[0039] Reference Figures 1 to 3 To improve the protective function of mobile phone cases for foldable screen phones, this utility model proposes an integrated foldable screen phone case, including a top cover 1 and a bottom cover 2. The top cover 1 and the bottom cover 2 are integrally formed, and the bottom cover 2 is disposed on one side of the top cover 1. A connecting rib 3 is provided between the two. It should be noted that the connecting rib 3 is made of a flexible material. The materials of the top cover 1 and the bottom cover 2 can be selected from various options, as long as the top cover 1, the bottom cover 2 and the connecting rib 3 can be made by an integral molding process such as secondary injection molding. Because the connecting rib 3 is made of a flexible material, the top cover 1 can rotate relative to the bottom cover 2 through the connecting rib 3, thereby matching the screen folding or unfolding function of the foldable screen phone.
[0040] In this invention, the connecting rib 3 connects the top cover 1 and the bottom cover 2 as a whole. Therefore, when the top cover 1 and bottom cover 2 are fitted onto the foldable phone, the phone case has multiple stress points, reducing the possibility of the phone case detaching from the phone and solving the core problem of traditional split-type protective cases easily falling off. Specifically, the connecting rib 3 can be set to always be taut, that is, when the phone case is installed on the phone, the connecting rib 3 is stretched, further reducing the possibility of the phone case detaching from the phone. Alternatively, considering the lifespan of the connecting rib 3 and the frequency of use when the foldable screen is unfolded, the connecting rib 3 can be relaxed when the phone is folded, but taut when the phone is unfolded, thereby improving the overall fixation of the phone case when the phone is unfolded and reducing the possibility of the phone case detaching from the phone. The state of the connecting rib 3 can be specifically set according to actual design requirements and different phone models, which will not be elaborated here.
[0041] Reference Figures 2 to 4 Based on the above, it can be seen that the connecting rib 3 is actually the key to reducing the risk of the phone case detaching from the phone. Compared with the overall size of the phone case, the connecting rib 3 is relatively small, so it may break under the influence of the external environment. To reduce the impact of the external environment on the connecting rib 3, a protective sheet 5 is also provided between the top cover 1 and the bottom cover 2 in this utility model. The protective sheet 5 is used to shield the connecting rib 3. The setting of the protective sheet 5 can effectively isolate the impact of the external environment on the connecting rib 3, thereby ensuring the service life of the connecting rib 3. In addition, the setting of the protective sheet 5 can effectively prevent dust and foreign objects from entering the gap of the phone hinge, extending the service life of the device. Furthermore, the integrated design of the protective sheet 5, the top cover 1, and the bottom cover 2 significantly enhances the fit between the phone case and the phone, greatly reducing the risk of the case detaching from the phone in case of accidental drop. Combined with the reinforced protection of the central axis by the protective sheet 5, the drop resistance of the foldable screen phone in daily use is comprehensively improved.
[0042] Reference Figures 4 to 6 Furthermore, to secure the protective sheet 5, an L-shaped plate 4 is provided on the bottom cover 2. The L-shaped plate 4 supports the protective sheet 5. Specifically, one side of the L-shaped plate 4 is fixed to the bottom cover 2, thus exposing one side of the L-shaped plate 4, and the protective sheet 5 is fixedly mounted on the exposed side of the L-shaped plate 4. The L-shaped plate 4 provides a supporting structure for the protective sheet 5, effectively dispersing external impact forces, especially when the phone is folded or unfolded, and enhancing the structural stability of the central axis. This design not only reduces the risk of deformation of the protective sheet 5 due to long-term stress, but also further improves the overall bending resistance of the protective case, ensuring reliable protection for the foldable screen phone even in extreme usage scenarios.
[0043] In this utility model, the L-shaped plate 4 can be made of various materials, and the way the L-shaped plate 4 is fixed to the bottom cover 2 varies depending on the material. Specifically, the L-shaped plate 4 can be made of metal, and the bottom cover 2 can also be made of metal. In this case, the L-shaped plate 4 can be fixed to the bottom cover 2 by means such as riveting, screwing, and hinge, or it can be fixed to the bottom cover 2 by a detachable connection method such as a spring buckle. When the L-shaped plate 4 is made of plastic or acrylic, it can be integrally formed on the bottom cover 2. However, it should be noted that when the L-shaped plate 4 is not made of metal, it can also be fixed to the bottom cover 2 by means such as riveting, screwing, and hinge. When the L-shaped plate 4 is not made of plastic or acrylic, it can also be integrally formed on the bottom cover 2. The fixing method between the L-shaped plate 4 and the bottom cover 2 can be selected according to the actual mobile phone model and design requirements.
[0044] Reference Figures 4 to 6 Furthermore, when the L-shaped plate 4 is connected to the bottom cover 2 via spring clips, this detachable design greatly enhances the product's ease of maintenance. Users or maintenance personnel can quickly disassemble the L-shaped plate 4 for individual replacement or maintenance without replacing the entire protective shell, thus reducing operating costs. Simultaneously, the elastic connection of the spring clips can absorb external impacts to a certain extent, further enhancing the protective shell's cushioning performance.
[0045] If the L-shaped plate 4 is fixed to the bottom cover 2 using a riveting process to form a rigid connection, the bonding strength between the L-shaped plate 4 and the bottom cover 2 is significantly enhanced. This connection method can withstand greater external impact, and is especially suitable for high-frequency use scenarios, ensuring that the protective case is not prone to loosening or falling off during long-term use, providing continuous and stable protection for foldable screen phones.
[0046] The screw connection allows for precise adjustment of the L-shaped plate 4, thus adapting to the different hinge positions of various foldable phone models. Users can fine-tune the angle or height of the L-shaped plate 4 according to their actual needs, ensuring a perfect fit between the protective sheet 5 and the central axis of the phone, improving protection while enhancing product compatibility and expanding its application range.
[0047] The hinge structure allows the L-shaped plate 4 to rotate flexibly relative to the bottom cover 2, thus adapting to the multi-angle hovering function of foldable screen phones. When the phone is at different folding angles, the L-shaped plate 4 can automatically adjust its posture to continuously provide support for the protective plate 5, ensuring that the protective case remains stable in various usage scenarios without affecting the normal folding operation of the phone.
[0048] The integrated design of the L-shaped plate 4 and the bottom cover 2 simplifies the manufacturing process, reduces the number of parts and assembly steps, and lowers manufacturing costs. Furthermore, this integrated structure eliminates potential weaknesses in traditional connection methods, enhancing the overall structural strength and durability of the protective shell and ensuring that it is less prone to breakage or loosening during long-term use.
[0049] As is well known, the hinge of a foldable phone is a relatively fragile component. To improve the protective effect of the phone case, based on the above, the L-shaped plate 4 can be made of a flexible material or hinged to the bottom cover 2, thus giving it the ability to deform or move. Furthermore, the L-shaped plate 4 is equipped with several magnets 41. When the phone is folded, the magnets 41 attract to the hinge, enhancing the fit between the case and the phone and preventing accidental detachment. Simultaneously, the attraction of the magnets 41 helps to distribute some of the pressure on the hinge during folding, reducing wear caused by uneven stress over time and extending the lifespan of the foldable phone, especially suitable for high-frequency folding scenarios.
[0050] Reference Figures 6 to 7 Furthermore, correspondingly, the protective sheet 5 needs to be fixed to the L-shaped plate 4 to cover the L-shaped plate 4, thereby covering the connecting rib 3. To ensure the covering effect of the protective sheet 5 on the connecting rib 3, the protective sheet 5 can be magnetically fixed to the L-shaped plate 4, or the protective sheet 5 can be integrally molded onto the L-shaped plate 4, or other detachable or fixing methods can be used. It should be noted that, as the component ultimately presented to the user's senses, the protective sheet 5 needs to have more material options than the L-shaped plate 4. In this utility model, the protective sheet 5 can be made of materials such as metal, silicone, rubber, acrylic, or leather. In combination with the above, the protective sheet 5 can be fixed to the L-shaped plate 4 by magnetic attraction, or different fixing methods can be selected according to the different materials of the protective sheet 5. For example, when the protective sheet 5 is made of leather, leather processing technology such as leather patching can be selected; when the protective sheet 5 is made of plastic, integral molding methods such as injection molding can be selected for fixing. The design of the protective sheet 5 using magnetic fixation or integral molding with the L-shaped plate 4 takes into account both flexibility and integrity. The detachable connection allows users to quickly replace the protective sheet 5 as needed, such as switching between different colors or materials, enhancing the product's personalized experience; while the fixing method further strengthens the structural strength of the protective sheet 5 and the L-shaped plate, ensuring that it is not easy to loosen or fall off during long-term use, thus improving the reliability of protection.
[0051] Reference Figure 8Furthermore, considering the convenience of daily use and the usage scenarios of foldable screen phones, a support plate 6 is provided on the protective sheet 5 to support the phone. Specifically, a groove 7 can be formed on the protective sheet 5 to accommodate the support plate 6. One end of the support plate 6 is rotatably connected to the groove 7, while the other end of the support plate 6 can be fixed to the groove 7 using a magnetic or other detachable fixing method. Thus, in normal conditions, the support plate 6 can be accommodated in the groove 7 to avoid affecting the daily use of the phone. However, in scenarios where phone support is required, the support plate 6 can still be used to support the phone. Of course, the groove 7 can be omitted, allowing the support plate 6 to be directly set on the protective sheet 5. Alternatively, the support plate 6 can be detachably set on the protective sheet 5, and the protective sheet 5 can also have several recesses for accommodating the ends of the support plate 6, or protrusions on the protective sheet 5 that cooperate with the ends of the support plate 6. Regardless of the setup, the support plate 6 on the protective plate 5 provides users with multi-angle support, allowing the foldable phone to be placed stably in an upright or tilted position. This design expands the phone's usage scenarios; for example, when watching videos in landscape mode, the phone can be propped up on a table to free up your hands; it also maintains a stable angle during video calls, improving ease of use. The addition of the support plate 6 further enhances the practicality of the protective case, making it not only protective but also a tool for auxiliary support.
