An integrated mobile phone protective case with an embedded flexible magnetic ring

Abstract

This application relates to an integrated mobile phone case with an embedded flexible magnetic ring, comprising a back panel and a magnetic component integrally formed within the back panel. A straight line passing through and parallel to the surface of the back panel is designated as a fold line. A flexible region that can be bent along any of the fold lines is formed on the back panel. The magnetic component is a flexible magnetic ring seamlessly connected end to end. Viewed from any direction, the flexible magnetic ring is completely located within the flexible region. When the back panel is bent around any fold line, the magnetic ring follows the back panel and bends around the fold line. By integrally forming a seamless flexible magnetic ring within the flexible region of the back panel, the magnetic ring can bend synchronously with the back panel when the mobile phone case is bent, preventing damage to the case and maintaining good magnetic attraction performance.

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. 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 car mounts, wireless charging positioning, and phone clips. Therefore, embedding magnetic components in phone cases has become a common requirement. Currently, most common magnetic phone cases use rigid magnetic rings or segmented magnetic strips as magnetic components. These rings or strips are typically made of hard magnetic materials (such as sintered neodymium iron boron) and are installed inside the back panel of the case via inserts or adhesives to cooperate with external magnetic devices. However, for flexible phone cases, when users install or remove their phones, the case body bends, but the internal rigid magnetic ring cannot bend accordingly, easily causing localized deformation or even breakage of the case, affecting its lifespan. Therefore, it is necessary to provide a method for setting up magnetic components in flexible phone cases that can bend with the case body while maintaining good magnetic performance. Utility Model Content

[0003] The purpose of this application is to provide a method for setting up magnetic components in a flexible mobile phone case that allows the case to bend with the case body while maintaining good magnetic attraction performance.

[0004] According to one aspect of this application, an integrated mobile phone protective case with an embedded flexible magnetic ring is provided, including a back plate and a magnetic component integrally formed in the back plate. A straight line passing through the surface of the back plate and parallel to it is referred to as a fold line. A flexible area that can be bent along any of the fold lines is formed on the back plate.

[0005] The magnetic component is a flexible magnetic ring that is seamlessly connected end to end. When viewed from any direction, the flexible magnetic ring is completely located within the flexible area. When the back plate bends around any fold line, the magnetic ring follows the back plate and bends around the fold line.

[0006] More preferably, the integrated phone case also includes:

[0007] The groove is recessed within the back plate, and when viewed along the direction perpendicular to the back plate, the groove is an annular groove adapted to the shape and size of the flexible magnetic ring.

[0008] Furthermore, when viewed from any direction, the groove is completely located within the flexible area. When the back plate bends around any fold line, the groove follows the back plate as it bends around the fold line.

[0009] More preferably, the flexible region is made of a flexible material, and the flexible magnetic ring is completely enclosed within the flexible material of the flexible region.

[0010] More preferably, the backplate is injection molded using an injection molding process, and the flexible magnetic ring is integrally formed within the backplate during the injection molding process.

[0011] More preferably, the flexible area partially or completely covers the back panel.

[0012] More preferably, the integrated phone case also includes:

[0013] The frame is connected to the back panel, and in the direction of extension of the fold line, the frame and the adjacent flexible area are made of the same flexible material.

[0014] More preferably, the border includes: a long border extending along the length direction of the phone, and a short border extending along the width direction of the phone.

[0015] More preferably, the fold line parallel to the vertical line of the long border is called the horizontal fold line, and the fold line parallel to the vertical line of the short border is called the vertical fold line.

[0016] If the phone case is designed to fold along a horizontal fold line to separate the phone and the phone case, then the flexible area covers at least the central area of ​​the back panel in a direction parallel to the short frame.

[0017] If the phone case is designed to fold along a longitudinal fold line to separate the phone and the phone case, then the flexible area covers at least the central area of ​​the back panel along a direction parallel to the long frame.

[0018] More preferably, the material of the flexible region is one or more of thermoplastic polyurethane elastomer, thermoplastic polyester elastomer, room temperature vulcanizing silicone rubber, polyolefin elastomer, or synthetic rubber.

[0019] More preferably, the flexible magnetic ring is a flexible magnetic material composed of magnetic powder and elastic silicone.

[0020] This application has the following beneficial effects:

[0021] By integrally molding a flexible magnetic ring with seamless connection at both ends within the flexible area of ​​the back panel, the magnetic ring can bend synchronously with the back panel when the phone case is bent, avoiding damage to the case and maintaining good magnetic attraction performance.

[0036] Please refer to Figures 1-9 This embodiment provides an integrated mobile phone protective case 100 with an embedded flexible magnetic ring. The protective case includes a back plate 10 and a magnetic component 20 integrally formed within the back plate 10. For ease of description, a straight line passing through and parallel to the surface 11 of the back plate 10 is defined as a fold line L. In this embodiment, a flexible region 30 is formed on the back plate 10, and the flexible region 30 can be bent along any of the fold lines L.

[0037] Specifically, the back panel 10 can be made of elastic or semi-elastic material, and the flexible area 30 is formed in a preset position on the back panel 10, so that when the protective case needs to be slightly pried open partially or entirely when assembling or disassembling the mobile phone, the flexible area 30 can be elastically bent in a direction parallel to the fold line L, thereby preventing the back panel 10 from deforming or breaking as a whole.

[0038] The magnetic component 20 is a flexible magnetic ring 21 seamlessly connected end to end. This magnetic ring 21 has a closed circular structure without any breaks, forming a continuous magnetic circuit, which helps improve the uniformity of the magnetic field distribution and the magnetic attraction effect. The magnetic ring 21 is made of a flexible magnetic material, such as neodymium iron boron magnetic particles as the main filler, and elastic silicone or similar elastomers as the bonding matrix, formed through conventional mixing or molding processes. It possesses a certain degree of flexibility and can change shape with the bending of the back plate 10.

[0039] Viewed from any direction, the flexible magnetic ring 21 is completely located within the flexible area 30 of the back plate 10. Since the flexible area 30 and the back plate 10 are an integral structure and can be bent along any fold line L, when the user installs or removes the phone case 100, or when the back plate 10 is bent during use, the magnetic ring 21 can bend synchronously with the back plate 10 along the fold line L without breaking, peeling, or stress concentration, thereby avoiding damage to the case or affecting the magnetic attraction function.

[0040] In this embodiment, the integrated mobile phone protective case 100 further includes a groove 40. The groove 40 is an annular groove formed by recessing along the thickness direction of the back plate 10, and its shape and size match the flexible magnetic ring 21. Viewed in a direction perpendicular to the back plate 10, the groove 40 has a circular structure, which can accommodate the flexible magnetic ring 21 and stably position it.

[0041] Viewed from any direction, the groove 40 is entirely located within the flexible region 30 of the back plate 10. Since the flexible region 30 can bend along any fold line L, and the groove 40 and the flexible region 30 are an integral structure, when the back plate 10 bends, the groove 40 also bends synchronously along the fold line L, ensuring that the flexible magnetic ring 21 inside the groove 40 is not constrained or damaged. This not only improves the fixing stability of the magnetic ring 21 but also avoids damage to the back plate 10 caused by local protrusion or uneven force on the magnetic ring.

[0042] In this embodiment, the flexible region 30 of the backplate 10 is made of a flexible material. This flexible material can be thermoplastic polyurethane elastomer (TPU), thermoplastic polyester elastomer (TPEE), room temperature vulcanizing silicone rubber, polyolefin elastomer (POE), synthetic rubber, or any combination thereof. The flexible region 30 has better bending performance and elastic recovery capability than other regions of the backplate 10, allowing the protective sleeve 100 to deform to a certain extent without breaking during assembly, disassembly, or use.

[0043] The flexible magnetic ring 21 is completely embedded within the flexible region 30 and is fully encased in the flexible material. This prevents the magnetic ring 21 from being directly exposed to the outside environment, thus avoiding scratches, corrosion, or peeling during daily use. It also allows the magnetic ring to deform synchronously with the flexible region 30 when the back plate 10 is bent, ensuring the structural integrity and magnetic attraction effect of the magnetic ring 21. Simultaneously, the flexible material also acts as a buffer, reducing stress concentration on other parts of the back plate 10 caused by the magnetic ring 21, thereby improving the overall durability and reliability of the protective cover 100.

[0044] In this embodiment, the back plate 10 is manufactured using injection molding. During the injection molding process, the flexible magnetic ring 21 is pre-positioned in the corresponding position within the injection mold, or the flexible magnetic ring 21 and the back plate material are simultaneously injected into the mold. Through in-mold insert technology or secondary injection molding, the flexible magnetic ring 21 and the back plate 10 are integrally formed. In this way, the flexible magnetic ring 21 is firmly fixed within the flexible area 30 of the back plate 10 without the need for additional adhesive or snap-fit ​​structures, avoiding the risk of the magnetic ring loosening or shifting. Simultaneously, the injection molding process allows the flexible magnetic ring 21 to be completely encased in the back plate material or flexible material, further improving durability and protective performance. This ensures that during the assembly, disassembly, and use of the protective sleeve 100, the magnetic ring 21 can bend synchronously with the back plate 10 without affecting the magnetic attraction effect.

[0045] In this embodiment, the flexible area 30 on the back plate 10 can be designed to partially or completely cover the back plate 10 as needed.

[0046] When the flexible area 30 is partially covered, it is usually located in the middle area of ​​the back plate 10 or the periphery of the magnetic component 20. Flexible material is only provided at the location where bending or stress release is required, so that the protective sleeve 100 has elasticity in key parts, which can ensure the convenience of assembly and disassembly, while maintaining the overall strength of other areas of the back plate 10.

[0047] When the flexible area 30 is fully covered, the flexible material extends along the entire surface of the back plate 10, giving the entire back plate 10 a certain degree of flexibility and toughness. In this form, the flexible magnetic ring 21 is arranged in a completely flexible substrate, and each area of ​​the back plate 10 can be elastically bent along any fold line L, adapting to more operating scenarios and improving drop and impact resistance.

[0048] Whether the flexible area 30 is partially or completely covered, it is integrally formed with the back plate 10, and the flexible magnetic ring 21 is located within the flexible area 30, so that the magnetic ring 21 always changes synchronously with the bending action of the back plate 10, ensuring the overall durability and magnetic attraction performance of the protective cover 100.

[0049] In this embodiment, the integrated mobile phone case 100 also includes a frame 50. The frame 50 is connected to the back panel 10 and forms circumferential protection for the mobile phone around the periphery of the back panel 10. In order to make the case 100 have good overall flexibility during installation, removal and use, the portion of the frame 50 adjacent to the flexible area 30 on the back panel 10 is made of the same flexible material as the flexible area 30.

[0050] Specifically, the frame 50 may include a long frame 51 extending along the length of the phone and a short frame 52 extending along the width of the phone. Since the flexible area 30 can be elastically bent along the fold line L, when the extension direction of the fold line L passes through the frame 50, the frame 50 and the flexible area 30 maintain the same material and are continuously formed, so that the frame 50 will not form a rigid obstruction when the protective case 100 is bent, thereby avoiding local stress concentration or breakage of the protective case, and improving durability and comfort.

[0051] Specifically, the long frame 51 is located on the left and right sides of the protective case 100, and is basically parallel to the long axis of the phone, and is used to protect and limit the long side of the phone; the short frame 52 is located at the top and bottom ends of the protective case 100, and is basically parallel to the short axis of the phone, and is used to protect and limit the short side of the phone.

[0052] The long frame 51 and the short frame 52, together with the back panel 10, form a circumferential ring structure, allowing the phone to be securely embedded in the protective case 100. Since the long frame 51 and the short frame 52 are connected to the flexible area 30 of the back panel 10, the same flexible material as the flexible area 30 can be used in these areas to ensure that the long frame 51 and the short frame 52 can undergo moderate elastic deformation with the back panel 10 during phone assembly or disassembly, thereby reducing the resistance between the phone and the protective case 100 and preventing cracks or permanent deformation of the protective case.

[0053] In this embodiment, the fold line parallel to the vertical line of the long frame 51 is defined as the horizontal fold line L1, and the fold line parallel to the vertical line of the short frame 52 is defined as the vertical fold line L2. The horizontal fold line L1 extends substantially along the width direction of the phone, and the vertical fold line L2 extends substantially along the length direction of the phone.

[0054] When the phone case 100 is designed to fold along the horizontal fold line L1 to separate the phone from the case, the flexible area 30 of the back panel 10 covers at least the central area of ​​the back panel 10 along the direction parallel to the short frame 52. This ensures that when the case 100 is bent in the width direction, the central area has sufficient flexibility to allow the case to undergo moderate elastic deformation without breaking.

[0055] When the phone case 100 is designed to fold along the longitudinal fold line L2 to separate the phone from the case, the flexible area 30 of the back panel 10 covers at least the central area of ​​the back panel 10 along the direction parallel to the long frame 51. This ensures that when the case 100 is bent in the length direction, the central area also has flexibility, facilitating the opening or rebound of the case and avoiding stress concentration and damage caused by local rigidity.

[0056] In this way, by integrally forming a flexible magnetic ring 21 with seamless connection end to end in the flexible area 30 of the back panel 10, the magnetic ring 21 can bend synchronously with the back panel 10 when the mobile phone case 100 is bent, so as to avoid damage to the case and maintain good magnetic attraction performance.

[0057] 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.
