Description

Technical Field

[0001] This application relates to mobile phone cases, and more particularly to mobile phone cases with embedded flexible magnetic rings. Background Technology

[0002] With the widespread use of smartphones, phone cases have become an indispensable accessory in daily life. Phone cases not only provide cushioning, drop protection, and scratch protection for phones during daily carrying and use, but also often incorporate magnetic functionality for applications such as wireless charging, car mounts, and magnetic attachments. Therefore, the demand for embedded magnetic components in phone cases is constantly increasing. Currently, most common magnetic phone cases use rigid magnetic rings or segmented magnetic strips as magnetic components. These rings or strips are usually made of hard magnetic materials (such as neodymium iron boron) and are installed inside the back panel of the case through inserts or adhesives to cooperate with external magnetic devices. Existing phone cases generally adopt a one-piece molding method, such as one-time injection molding or a combination of rigid and flexible molding, with magnets or metal rings placed inside the shell. When a flexible phone case is bent, the internal magnetic components cannot bend accordingly, easily causing deformation or damage to the case, and even affecting its lifespan. Furthermore, one-piece molded cases require replacement of the entire case when partial damage or functional failure occurs, and have shortcomings in terms of structural maintainability, magnetic reliability, and functional expandability. Therefore, it is necessary to provide a method for setting up magnetic components in flexible mobile phone cases that allows for easy installation and removal, adaptability to bending, and maintenance of good magnetic attraction performance.

[0045] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] like Figures 1-11 As shown, this embodiment provides a spliced ​​mobile phone protective case with an embedded flexible magnetic ring. The protective case is composed of a first housing part 10 and a second housing part 20 spliced ​​together, which cooperate to form a complete housing structure. To achieve the magnetic attraction function, a magnetic element 30 is provided between the first housing part 10 and the second housing part 20.

[0049] The magnetic component 30 adopts a flexible magnetic ring 31 structure with seamless connection from end to end. This structure allows the magnetic ring to form a closed loop and has a certain degree of flexibility so that it remains intact when the protective sleeve is removed or bent, deforming with the shell and avoiding breakage or loosening.

[0050] To accommodate the flexible magnetic ring 31, a groove 11 adapted to the magnetic ring is formed on the first housing portion 10. The flexible magnetic ring 31 is embedded in the groove 11, which not only securely positions it but also prevents it from being exposed, improving the overall aesthetics and durability of the protective cover. The second housing portion 20 at least partially covers the groove 11, further protecting and fixing the magnetic ring and preventing it from shifting or being damaged by external forces.

[0051] Furthermore, to ensure the protective sleeve possesses the necessary flexibility during bending or assembly / disassembly, flexible regions 40 are formed on both the first housing portion 10 and the second housing portion 20. The flexible regions 40 cover the portion of the first housing portion 10 that forms the groove 11 and the corresponding portion of the second housing portion 20 that covers the groove 11, giving the area where the flexible magnetic ring 31 is located a moderate deformability. This allows the magnetic ring to maintain stable magnetic attraction performance by deforming synchronously with the housing when the protective sleeve is subjected to force.

[0052] As shown in the figure, in a preferred embodiment, the first housing portion 10 is a back plate 12, with the side of the back plate 12 closest to the mobile phone referred to as the front 12a and the side furthest from the mobile phone referred to as the back 12b. When the groove 11 is formed on the front 12a of the back plate 12, the second housing portion 20 can adopt different covering methods: it can completely cover the entire front 12a, or it can only partially cover the front 12a, but the covered part remains flush with the front 12a.

[0053] Example 1

[0054] In this embodiment, the groove 11 is formed on the front side 12a of the back plate 12, and the second housing part 20 only partially covers the front side 12a of the back plate, and the covered part is flush with the front side 12a, so that the protective cover has a flat and beautiful appearance, while ensuring the stable fixation of the flexible magnetic ring 31.

[0055] In this embodiment, the spliced ​​mobile phone case 100 also includes a frame 50. The frame 50 is formed around the periphery of the first housing portion 10 and extends along the vertical back plate 12 toward the side away from the back surface 12b of the back plate 12, to provide circumferential structural support, making the case more stable during installation and use.

[0056] To achieve flexibility in the protective case, flexible regions 40 are provided on both the first housing portion 10 and the second housing portion 20. The flexible regions 40 include a first flexible region 41 formed on the first housing portion 10 and a second flexible region 42 formed on the second housing portion 20. A straight line passing through and parallel to the front surface 12a of the back panel is denoted as the fold line L. The first flexible region 41 and the second flexible region 42 can be bent around either fold line L.

[0057] The first flexible region 41 covers at least the portion of the first housing part 10 that forms the groove 11, so that the flexible magnetic ring 31 can remain intact as the housing deforms; the second flexible region 42 covers the entire second housing part 20, so that the part as a whole is flexible and can cooperate with the first housing part when it is loaded, unloaded or bent.

[0058] Example 2

[0059] In this embodiment, the groove 11 is formed on the front surface 12a of the back plate 12, and the second housing portion 20 completely covers the front surface 12a of the back plate, so that the flexible magnetic ring 31 is protected from all directions inside the housing. Through this covering method, the second housing portion 20 not only fixes and protects the flexible magnetic ring 31, but also improves the overall integrity and durability of the protective cover.

[0060] In this embodiment, the phone case 100 also includes a frame 50. The frame 50 is formed around the periphery of the second housing portion 20 and extends along the direction perpendicular to the back plate 12 toward the side away from the back plate 12, for supporting and securing the edges of the phone. This frame structure helps to enhance the impact resistance and deformation resistance of the case.

[0061] To maintain the flexibility of the protective cover during installation or removal, a flexible region 40 is provided on the second housing portion 20. In this embodiment, the flexible region 40 includes only the second flexible region 42. A straight line passing through and parallel to the front side 12a of the back plate is denoted as the fold line L. The second flexible region 42 can be bent around any fold line L, thereby allowing the protective cover to adapt to different bending requirements during operation.

[0062] The second flexible region 42 includes at least the portion of the second housing portion 20 covering the groove 11, so that the flexible magnetic ring 31 remains stable during deformation and is prevented from being damaged or falling off due to external forces.

[0063] Example 3

[0064] In this embodiment, the groove 11 is formed on the front surface 12a of the back plate 12, and the second housing portion 20 completely covers the front surface 12a of the back plate, thus providing full protection for the flexible magnetic ring 31. Through this covering method, the second housing portion 20 not only serves to fix the magnetic ring, but also provides an additional protective layer for the housing, improving the overall robustness and durability.

[0065] In this embodiment, the modular phone case 100 also includes a frame 50. The frame 50 is formed around the perimeter of the first housing portion 10 and extends along the vertical back plate 12 toward the side away from the back surface 12b of the back plate 12. The frame 50 is integrally formed with the back plate 12, providing circumferential structural support for the phone and making the case more stable during assembly, use, and stress.

[0066] To ensure the protective cover remains flexible during installation, removal, or bending, flexible regions 40 are provided on both the first housing portion 10 and the second housing portion 20. The flexible regions 40 include a first flexible region 41 formed on the first housing portion 10 and a second flexible region 42 formed on the second housing portion 20. A straight line passing through and parallel to the front surface 12a of the back panel is denoted as the fold line L. Both the first flexible region 41 and the second flexible region 42 can be bent around either fold line L.

[0067] The first flexible region 41 includes at least the portion of the first housing part 10 that forms the groove 11, so that the position of the flexible magnetic ring 31 can remain intact as the housing deforms; the second flexible region 42 covers the entire second housing part 20, so that the outer layer can deform synchronously with the first housing part 10 when subjected to force, thereby reducing internal stress concentration.

[0068] More preferably, when viewed along the direction of the vertical back plate 12, the groove 11 is an annular groove that is adapted to the shape and size of the flexible magnetic ring 31, so that the flexible magnetic ring 31 can fit tightly with the groove 11 and avoid loosening or displacement.

[0069] Furthermore, when viewed from any direction, the groove 11 is completely located within the flexible region 40. When the back plate 12 bends along any fold line L, the groove 11 can bend synchronously with the back plate 12, so that the flexible magnetic ring 31 embedded therein remains intact when the shell is subjected to force or deformation, and does not break or fall off.

[0070] More preferably, the flexible region 40 is made of a flexible material to ensure that the protective sleeve has sufficient deformation capacity during installation, removal, or bending. The flexible material may be one or more combinations of thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, room temperature vulcanizing silicone rubber, polyolefin elastomer, or synthetic rubber.

[0071] The flexible magnetic ring 31 is completely encased within the flexible material of the flexible region 40. This encapsulation structure isolates the magnetic ring from the external environment, preventing damage from impacts or friction during use of the protective case. Simultaneously, it deforms in tandem with the flexible region when the protective case is bent or deformed. This structure not only ensures stable magnetic performance but also enhances the durability and safety of the protective case.

[0072] More preferably, the bezel 50 includes a long bezel 51 extending along the length of the phone and a short bezel 52 extending along the width of the phone. For ease of description, the fold line parallel to the vertical line of the long bezel 51 is denoted as the horizontal fold line L1, and the fold line parallel to the vertical line of the short bezel 52 is denoted as the vertical fold line L2.

[0073] In this structure, when the phone case is designed to be folded along the horizontal fold line L1 to separate the phone and the case, the flexible area 40 covers at least the middle area of ​​the first housing portion 10 along the direction parallel to the short frame 52, so that the case has sufficient flexibility when folded horizontally to ensure a smooth disassembly and assembly process.

[0074] Similarly, when the phone case is designed to fold along the longitudinal fold line L2, the flexible area 40 covers at least the middle area of ​​the first housing part 10 along the direction parallel to the long frame 51, so that the case can also achieve stable bending when folded longitudinally, ensuring that the flexible magnetic ring 31 maintains reliable positioning and magnetic attraction performance in the bending state.

[0075] More preferably, the flexible region 40 can be made of a variety of flexible materials to meet different performance requirements. The material can be one of thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, room temperature vulcanizing silicone rubber, polyolefin elastomer, or synthetic rubber, or any combination of the above materials. These materials all have good elasticity and durability, are not prone to aging or cracking during long-term use, and provide sufficient resilience so that the protective sleeve can return to its original shape after bending.

[0076] By using the aforementioned flexible material, the flexible area 40 not only provides the necessary deformation space when the mobile phone protective case is removed or subjected to force, but also plays a buffering and protective role for the flexible magnetic ring 31 embedded therein, thereby improving the overall stability and service life.

[0077] More preferably, the flexible magnetic ring 31 is made of a composite of magnetic powder and elastic silicone. By uniformly dispersing the magnetic powder in the elastic silicone matrix, the magnetic ring not only possesses the required magnetic attraction properties but also exhibits good flexibility and durability. This structure allows the flexible magnetic ring 31 to deform synchronously with the phone case when it is removed, bent, or subjected to force, preventing breakage, deformation, or detachment, and ensuring stable magnetic force output.

[0078] By embedding a seamlessly connected flexible magnetic ring 31 between the first housing part 10 and the second housing part 20, and covering and fixing it with the second housing part 20, while providing flexible areas 40 on both, the protective cover can undergo necessary deformation during installation, removal, or bending. The flexible magnetic ring 31 can deform accordingly without breaking or loosening. This structure not only ensures the stable magnetic attraction performance of the magnetic ring, but also effectively avoids damage caused by stress on the housing, significantly improving the durability and flexibility of the protective cover. It also provides a structural basis for expanding magnetic attraction functions and adapting to different usage scenarios.

[0079] The embodiments described above are merely illustrative of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
