Description

Technical Field

[0001] This utility model relates to the field of mobile phone peripheral technology, and in particular to a folding mobile phone protective case. Background Technology

[0002] With the continuous advancement of technology, foldable phones, due to their unique foldable design, offer a larger screen display area while maintaining portability, and have gradually gained widespread popularity among consumers. To better protect foldable phones, various protective cases have emerged.

[0003] Currently, there are protective cases on the market for foldable phones. When the phone is folded, the side of the case corresponding to the screen has a cutout. The original intention of this design was to allow users to easily touch the screen by threading their fingers through the cutout when the phone is folded, thus improving user convenience to some extent. However, this design has significant drawbacks. When the phone is accidentally dropped, the screen is exposed without any protective structure, making it extremely vulnerable to impacts. Foldable phone screens typically use advanced but fragile flexible screen technology. Once impacted, the screen is easily damaged, resulting in issues such as screen cracking or display abnormalities. This not only affects the normal use of the phone but also causes significant financial losses for the user.

[0004] To address the aforementioned issues, this patent proposes incorporating a transparent panel into the protective case. This transparent panel effectively protects the foldable phone's screen without obstructing the user's view of the screen. Users can operate the phone through the transparent panel as if operating directly on the screen, while simultaneously avoiding the risk of impact damage to the exposed screen, significantly improving the safety and reliability of the foldable phone in daily use.

[0036] This utility model proposes a foldable mobile phone protective case.

[0037] Please see Figures 1 to 8 In one embodiment of the present invention, the foldable mobile phone protective case includes a first housing 10 and a second housing 20, which are rotatably connected to each other for folding and unfolding. The first housing 10 includes a base plate 11 and a first enclosure 12 surrounding the base plate 11. The first enclosure 12 has a first opening 13 on the side facing the second housing 20. The second housing 20 includes a second enclosure 23, a mounting frame 21, and a transparent plate 22. The transparent plate 22 is mounted on the mounting frame 21, and the second enclosure 23 surrounds the mounting frame 21. The second enclosure has a second opening 24 facing the first opening 13.

[0038] Specifically, in this embodiment, the first housing 10 consists of a base plate 11 and a first enclosure 12. The first enclosure 12 surrounds the perimeter of the base plate 11, forming a wrapping structure for the corresponding part of the phone (the left half of a left-right folding phone, or the upper half of a right-down folding phone). Simultaneously, the first enclosure 12 has a first opening 13 on the side facing the second housing 20. This notch breaks the continuity of the enclosure, forming a specific spatial structure. The second housing 20 includes three main components: a second enclosure 23, a mounting frame 21, and a transparent plate 22. The transparent plate 22 is fixedly mounted on the mounting frame 21, and the two together form an integral component. The second enclosure 23 surrounds the perimeter of the mounting frame 21, and together with the mounting frame 21 and the transparent plate 22, constitutes the complete structure of the second housing 20, forming a wrapping structure for the corresponding part of the phone (the right half of a left-right folding phone, or the lower half of a right-down folding phone). Furthermore, the second enclosure 23 has a second opening 24 facing the first opening 13, corresponding to the notch in the first housing 10.

[0039] The first housing 10 and the second housing 20 are connected in a rotatable manner, which allows them to fold and unfold to accommodate the use of a foldable phone. When the first housing 10 and the second housing 20 are unfolded, the first opening 13 of the first enclosure 12 and the second opening 24 of the second enclosure 23 are positioned opposite each other, forming a corresponding spatial structure (for placing the unfolded phone), with the enclosures of the two housings wrapping around the phone from different sides.

[0040] The rotatable design of the first housing 10 and the second housing 20 can perfectly adapt to the folded and unfolded states of the foldable phone, ensuring effective protection for the phone in both states.

[0041] The first enclosure 12 and the second enclosure 23 are respectively installed around the base plate 11 and the mounting frame 21, which can provide good protection for the edges and sides of the mobile phone and reduce the risk of damage to the mobile phone due to collisions or drops; the transparent plate 22 provides effective protection for the mobile phone screen without affecting operation, and prevents the screen from being directly exposed.

[0042] The transparent plate 22 corresponds to the screen of the folded phone after folding, and is used to protect the screen of the folded phone. At the same time, combined with the operable feature of the transparent plate 22, users can still operate the phone conveniently even when the protective case is installed, thus balancing protection and ease of use.

[0043] Furthermore, both the first housing 10 and the second housing 20 are made of soft rubber; the mounting frame 21 and the base plate 11 are made of hard material.

[0044] Specifically, the soft rubber enclosure in the first housing 10 and the second housing 20 is organically integrated with the rigid base plate 11 and mounting frame 21. The soft rubber enclosure surrounds the rigid base plate 11 and mounting frame 21, with the rigid parts providing a fixed foundation and support frame for the soft rubber enclosure. The soft rubber enclosure, in turn, relies on this frame to wrap around the phone. Together, they form the overall structure of the protective case, creating a composite structural system of "soft rubber enclosure + rigid support".

[0045] The soft rubber material of the protective case, with its flexibility, can fit snugly against the edges and sides of the phone. When the phone is bumped or dropped, its elastic deformation absorbs the impact force, effectively cushioning external damage to the phone. It also makes it easy for users to put the phone in or take it out of the protective case. The rigid base plate 11 and mounting frame 21 provide a stable structural support for the protective case, preventing it from deforming under stress during daily use. This ensures the installation stability of components such as the transparent plate 22, avoiding unnecessary pressure or damage to the phone screen and other parts due to deformation of the protective case, thus guaranteeing the overall protective performance and lifespan of the protective case.

[0046] This combination of soft and hard materials balances the flexibility and stability of the protective case, enhancing both the protection of the phone and the ease of use for the user.

[0047] The transparent panel 22 is made of glass; and / or, the soft rubber material is made of TPU; and / or, the rigid material is made of PC.

[0048] Specifically, the transparent glass panel 22 has high light transmittance, ensuring that users can clearly see the screen content without affecting the visual experience; its high hardness makes it resistant to scratches, maintaining a good operating surface for a long time, while the smooth surface makes the user feel smooth when operating.

[0049] TPU material, being a soft rubber, allows the protective case to fit snugly against the phone due to its flexibility and elasticity, effectively cushioning impacts and protecting the phone's edges; its wear resistance extends the lifespan of the protective case and makes it easy to install and remove the phone.

[0050] As a rigid material, PC material provides stable support for the protective case due to its high structural strength and impact resistance, preventing deformation of the case and ensuring the installation stability of components such as the transparent plate 22. This avoids damage to the phone due to deformation of the protective case and improves the overall protective performance of the case.

[0051] The glass plate has a thickness ranging from 0.5mm to 0.6mm. This thickness ensures the glass plate has sufficient hardness to resist scratches without increasing the overall thickness of the protective case, thus maintaining the portability of the foldable phone after the protective case is installed. At the same time, the moderate thickness ensures that the glass plate has a certain degree of toughness, effectively protecting the screen from minor impacts without easily shattering itself, balancing protective performance with ease of use. Furthermore, the relatively thin thickness does not significantly affect the sensitivity of user operation on the transparent plate 22, ensuring smooth operation.

[0052] Furthermore, the first housing 10 and the second housing 20 are integrally injection molded. A connecting wall 212 is formed between the first housing 10 and the second housing 20, connecting their upper ends. The first housing 10 and the second housing 20 can rotate at the connecting wall 212 to be folded and unfolded.

[0053] Specifically, the connecting wall 212 serves as the connection medium between the first housing 10 and the second housing 20. Since the three are integrally injection molded, the connecting wall 212 forms an inseparable integral structure with the first housing 10 and the second housing 20. The first housing 10 and the second housing 20 are linked together with the connecting wall 212 as the axis, allowing them to rotate relative to each other. The presence of the connecting wall 212 provides the necessary structural support and activity constraints for the folding and unfolding actions of both, ensuring that the rotation process proceeds in an orderly manner.

[0054] The integrated injection molding process ensures a tight connection and structural stability between the first shell 10 and the second shell 20, reducing potential loosening and gaps during component assembly and improving the overall robustness of the protective shell. The integrated connecting wall 212 design provides a reliable fulcrum for the rotation of the first shell 10 and the second shell 20, making their folding and unfolding movements smoother and more stable, avoiding jamming or detachment issues that may occur with traditional connection methods. Simultaneously, this integrated structure simplifies the production process, reduces manufacturing costs, and better adapts to the changing form factors of foldable phones, ensuring consistent protection for the phone in both folded and unfolded states.

[0055] Furthermore, the thickness of the connecting wall 212 increases from the middle to both sides.

[0056] Specifically, in this embodiment, the thickness of the connecting wall 212 is not uniformly distributed, but rather gradually increases from the center to both sides. As the connecting medium between the first housing 10 and the second housing 20, the special thickness distribution of the connecting wall 212 is adapted to the rotational requirements of the first housing 10 and the second housing 20. The center is the main stress-bearing area when the first housing 10 and the second housing 20 rotate; a thinner thickness provides better flexibility for rotation. Meanwhile, the connecting parts on both sides with the first housing 10 and the second housing 20 need to withstand greater forces; a thicker thickness enhances the stability of the connection, conforms to the integral injection-molded structure, and further strengthens the inseparable relationship between the three components.

[0057] This varying thickness design allows the connecting wall 212 to effectively enhance the overall structural strength while ensuring smooth rotation of the first housing 10 and the second housing 20. The thinner central section ensures flexible rotation and prevents jamming; the thicker sides enhance the deformation resistance at the connection points with the housings, reducing fatigue damage caused by prolonged rotation and extending the service life of the protective shell. Simultaneously, the optimized thickness distribution also improves the stress distribution of the connecting wall 212, resulting in more even stress distribution during folding and unfolding, further ensuring stability and reliability during use.

[0058] Furthermore, the minimum thickness of the connecting wall 212 is D, which is 2.2mm ≤ D ≤ 3mm.

[0059] Specifically, in this embodiment, the minimum thickness of the connecting wall 212 is set in the range of 2.2mm to 3mm, mainly based on the need to balance flexibility and structural strength.

[0060] From a flexibility perspective, the middle part of the connecting wall 212 serves as the main active area for the rotation of the first housing 10 and the second housing 20. The minimum thickness within this range can ensure smooth rotation and avoid jamming caused by excessive thickness, thus adapting to the usage scenarios of foldable phones that frequently fold and unfold.

[0061] From a structural strength perspective, this thickness range ensures that the connecting wall 212 has sufficient support and will not break or deform during long-term use due to excessive thinness. At the same time, in conjunction with the design of gradually thickening on both sides, it can effectively disperse the stress during rotation, enhance the stability of the connection with the shell, reduce fatigue damage, and ensure the service life and overall reliability of the protective shell.

[0062] Furthermore, the mounting frame 21 includes an integrally formed rectangular frame 211 and a perimeter 30, the perimeter 30 surrounding at least a portion of the perimeter of the rectangular frame 211, and the transparent plate 22 is mounted on the rectangular frame 211; the inner wall of the second enclosure 23 has a groove 231 for accommodating the perimeter 30.

[0063] Specifically, the perimeter 30 of the mounting frame 21 is integrally formed with the rectangular frame 211, creating a stable overall structure. The design of the perimeter 30 around the rectangular frame 211 provides auxiliary positioning and protection for the installation of the transparent panel 22. The groove 231 on the inner wall of the second enclosure 23 is structurally matched with the perimeter 30 of the mounting frame 21. Combined with the secondary injection molding process of first injection molding the mounting frame 21 and then injection molding the second enclosure 23, a tight and firm fit is formed between the two, thereby stably fixing the mounting frame 21 within the second enclosure 23. This process further enhances the connection stability between the mounting frame 21 and the second enclosure 23.

[0064] The rectangular frame 211 of the mounting frame 21 is integrally formed with the surrounding edge 30, enhancing the overall structural strength of the mounting frame 21 and ensuring that the transparent panel 22 is not easily loosened after installation, effectively protecting the edges of the transparent panel 22 from damage. The groove 231 on the inner wall of the second enclosure 23 fits with the surrounding edge 30 of the mounting frame 21, and with a specific injection molding process, it achieves precise assembly and tight connection between the mounting frame 21 and the second enclosure 23, preventing the mounting frame 21 from shaking or shifting during use and ensuring the overall structural stability of the second housing 20. This structural design and process also simplifies the assembly process, improves production efficiency, and makes the protective shell look cleaner and more aesthetically pleasing.

[0065] Furthermore, the edging 30 is provided around at least two of the four sides of the rectangular frame 211.

[0066] Specifically, in this embodiment, the perimeter 30 surrounds at least two of the four sides of the rectangular frame 211. It can be two opposite long sides, an adjacent long side and a short side, or even three or four sides. The specific number of sides can be flexibly set according to the actual protection and connection requirements.

[0067] When the edging 30 encloses at least two sides, it can significantly increase the contact area with the second shell 20 compared to enclosing only one side. For example, when two opposite long sides are enclosed, the contact area extends longitudinally along the rectangular frame 211, forming symmetrical force support; when adjacent long and short sides are enclosed, a connecting contact area is formed at the corner, enhancing the connection strength at the corner.

[0068] The increased contact area allows for a tighter connection between the second housing 20 and the surrounding edge 30, distributing the stress at the connection point and reducing the risk of localized stress concentration. This not only effectively improves the stability of the connection and reduces loosening caused by frequent folding, collisions, or shaking during use, but also enhances the overall structural rigidity of the second housing 20, making the transparent plate 22 more stable after installation and further ensuring the protective effect on the phone screen. Simultaneously, the multi-sided surrounding design provides more ample connection points for the injection molding of the mounting frame 21 and the second enclosure 23, enabling them to form a more robust integrated structure during the injection molding process and extending the service life of the protective shell.

[0069] Furthermore, the folding phone case also includes a central axis protective sleeve 40, which is rotatably connected to the base plate 11 to block the first opening 13 and the second opening 24 when the first housing 10 and the second housing 20 are folded, and to protect the central axis position of the folding phone.

[0070] Specifically, in this embodiment, the central axis protective sleeve 40 is rotatably connected to the base plate 11, which is a component of the first housing 10, thus forming a direct linkage with the first housing 10. The rotational movement can be coordinated with the folding and unfolding movements of the first housing 10 and the second housing 20. When the housing is folded, the central axis protective sleeve 40 blocks the first opening 13 and the second opening 24, forming a complete enclosure structure with the first enclosure 12 of the first housing 10 and the second enclosure 23 of the second housing 20, filling the gaps in protection. The magnets inside allow the central axis protective sleeve 40 to be tightly attracted to the central axis of the phone, working in conjunction with the first housing 10 and the second housing 20 to wrap and protect the phone, jointly constructing an all-round protection system.

[0071] The central axis protective sleeve 40 is rotatably connected to the base plate 11, ensuring rotational stability and coordination with the movement of the phone's casing. When folded, it precisely blocks the first opening 13 and the second opening 24, preventing the phone's central axis and surrounding components from being exposed to impacts or scratches. Magnets inside the central axis protective sleeve 40 enhance the connection between the sleeve and the phone's central axis, preventing displacement and improving protective stability. This design provides more complete protection, complementing the protective functions of the first and second casings 10, significantly improving overall protective performance and extending the phone's lifespan.

[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
