Technical Field

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

[0002] In the mobile phone accessory market, magnetic support ring stands are widely popular due to their convenience and practicality. Current product designs utilize a rotatable snap-fit ​​connection between the magnetic support ring and the phone case to meet diverse user needs for phone viewing angles in different scenarios. This design is undoubtedly well-intentioned, granting users a high degree of freedom. Users can easily adjust the angle of the magnetic support ring to display their phone in the most comfortable and suitable position, providing an excellent visual experience whether watching videos, making video calls, or reading documents.

[0003] However, with prolonged use and frequent rotation of the magnetic support ring during daily use, the following problem easily occurs: the magnetic support ring is prone to falling off the phone case's clasp structure due to the magnetic attraction. This issue seriously affects the user experience. The magnetic support ring, originally designed to improve convenience, now causes considerable inconvenience due to its frequent detachment. Utility Model Content

[0004] In order to overcome the defects of the prior art, this utility model proposes a magnetic support ring and a mobile phone case containing the same, which can solve the problem that the snap connection method used in the existing magnetic support ring structure is prone to falling off the snap structure of the mobile phone case due to magnetic attraction as the usage time increases.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The present invention provides a magnetic support ring, including a body and a mounting base. The mounting base is provided with a receiving groove. The body includes a rotating base and a support member. The rotating base and the support member are hinged together. The rotating base is rotatably connected to the receiving groove.

[0007] The preferred technical solution of this utility model is that the bottom of the support member is provided with a recessed receiving area, and a magnet is provided in the receiving area.

[0008] The preferred technical solution of this utility model is that a magnetic sheet is provided under the rotating base.

[0016] The beneficial effects of this utility model are:

[0017] This invention proposes a magnetic support ring and a phone case containing it. The magnetic support ring decomposes the connection structure with the phone case into two main modules: a mounting base and a main body. The mounting base, as the key carrier connecting the phone case and the main body, has a receiving groove that provides installation and positioning space for the rotating base. The receiving groove provides axial and radial dual limiting for the rotating base while maintaining sufficient rotation clearance to ensure smooth rotation. At the same time, the mounting base uses a high-strength adhesive layer to achieve irreversible rigid bonding with the mounting groove of the phone case. This adhesive method not only avoids the wear and loosening caused by repeated insertion and removal of traditional buckle structures, but its bonding strength can also withstand the instantaneous tensile force during the magnetic attraction process, making the mounting base and the phone case form a stable mechanical whole, fundamentally eliminating the risk of loosening of the connection structure.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1-9As shown, this embodiment provides a magnetic support ring, including a body and a mounting base 1. The mounting base 1 has a receiving groove 11. The body includes a rotating base 2 and a support member 3. The rotating base 2 and the support member 3 are hinged together, and the rotating base 2 is rotatably connected to the receiving groove 11. Addressing the technical challenge that current magnetic support rings connected to phone cases using rotatable snap fasteners are prone to detaching from the snap fastener structure due to long-term rotation and magnetic attraction, affecting user experience and product lifespan, this embodiment systematically constructs a solution that combines rotational flexibility with connection stability through innovative structural design and component collaboration. Its core lies in decomposing the connecting structure into two main modules: the mounting base and the main body. The mounting base, as the key carrier connecting the phone case and the main body, features a receiving groove that provides mounting and positioning space for the rotating base. This groove provides axial and radial dual restraints on the rotating base while maintaining sufficient rotational clearance to ensure smooth rotation. Simultaneously, the mounting base uses a high-strength adhesive layer to achieve an irreversible rigid bond with the mounting groove of the phone case. This adhesive method not only avoids the wear and loosening caused by repeated insertion and removal of traditional snap-fit ​​structures, but its bonding strength can also withstand the instantaneous tensile force during magnetic attraction, making the mounting base and the phone case a stable mechanical whole, fundamentally eliminating the risk of the connecting structure loosening. In the main body module, the rotating base achieves 360° horizontal rotation through precise cooperation with the receiving groove, meeting multi-angle support requirements. The hinge between the support component and the rotating base allows for fine-tuning of the vertical angle. Together, these two components construct a three-dimensional angle adjustment system. This solution, through the rigid bonding and precise rotational fit between the mounting base and the rotating base, the hinged angle adjustment between the support component and the rotating base, and the dynamic balance design between magnetic force and mechanical structure, avoids the wear risk of traditional snap-fit ​​structures while achieving a dual breakthrough in rotational flexibility and connection stability. It provides an innovative technical path for the reliable operation of magnetic support rings in complex usage scenarios. For manufacturers, mounting grooves can be easily machined directly onto the back of existing phone cases to adapt to the magnetic support ring of this embodiment, facilitating application and promotion.

[0033] Preferably, the bottom of the support member 3 has a recessed receiving area 31, within which a magnet 32 ​​is housed. The recessed receiving area provides a stable mounting space for the magnet, effectively constraining its position by limiting the physical space and preventing displacement due to external collisions or vibrations, thus ensuring the long-term stability of the magnetic attraction function. Compared to flat or simple protruding mounting methods, the recessed design integrates the magnet and support member into a single structural unit, enhancing the overall structural compactness and anti-interference capability. From the perspective of optimizing magnetic attraction performance, the recessed receiving area can directionally encapsulate the magnet, reducing the scattering of magnetic lines of force in non-target directions, allowing the magnetic force to act more concentrated on the mobile phone or other magnetic devices, significantly improving the magnetic attraction strength and response speed. Furthermore, the recessed structure provides a physical protective layer for the magnet, preventing oxidation and corrosion caused by long-term exposure to the external environment, thus extending the magnet's lifespan. By embedding the magnets into the bottom of the support, the mechanical structure of the magnetic components can be hidden, making the magnetic support ring look simpler and more aesthetically pleasing. At the same time, it reduces the risk of scratches caused by exposed magnetic components, balancing functionality and design aesthetics. This is a key breakthrough in the structural innovation of the magnetic support ring.

[0034] Preferably, a magnetic attracting sheet 4 is provided under the rotating base 2. When the magnetic support ring is engaged, the magnetic attracting sheet 4 is located directly below the magnet 32. As a key component for magnetic circuit optimization, the magnetic attracting sheet significantly enhances the overall efficiency of the magnetic attraction system. From the perspective of magnetic principles, the magnetic attracting sheet is usually made of a high-permeability material, which can guide and concentrate the magnetic lines of force generated by the magnet, making the magnetic field distribution more uniform and more directional. When the magnetic support ring is close to a mobile phone or other magnetic attraction device, the magnetic attracting sheet can effectively shorten the magnetic attraction response time, achieve rapid attraction, and improve the stability of attraction, reducing the risk of attraction failure caused by slight shaking due to external forces. The magnetic attracting sheet is located below the magnet, which can form a double-layer magnetic attraction structure. The attraction strength is enhanced through the magnetic force superposition effect, which is especially suitable for use scenarios that need to withstand large external forces (such as vehicle bumps). In addition, the magnetic attracting sheet can also serve as a buffer layer between the magnet and the rotating base, absorbing the stress impact caused by the instantaneous change of magnetic attraction force and protecting the structural integrity of the magnet and the rotating base. From a thermal management perspective, the magnetic sheet can assist in heat dissipation of the magnetic components, avoiding localized overheating caused by prolonged high-intensity magnetic attraction, and further improving the reliability and service life of the product. In this embodiment, the magnetic sheet is made of iron.

[0035] Preferably, a protective layer is provided below the magnetic attracting sheet 4. This protective layer is an indispensable protective measure in the design of the magnetic support ring structure. Specifically, in this embodiment, the protective layer is Mylar film. Mylar film is a thin film product made from polyester materials (such as PET, PI, etc.). Due to its excellent insulation, temperature resistance, and mechanical strength, it is widely used in electronics, electrical, and communication fields. Its core characteristics include chemical corrosion resistance, high temperature resistance, and dimensional stability. After the magnetic attracting sheet 4 is covered with Mylar film, the overall appearance is more aesthetically pleasing, wear is avoided, and magnetism is not blocked.

[0036] Preferably, the outer inner edge of the receiving groove 11 is provided with an inwardly extending annular locking protrusion 12, and the outer side of the rotating base 2 is provided with an annular groove 21 that matches the annular locking protrusion 12. The annular groove 21 and the annular locking protrusion 12 are rotatably engaged. The engagement design of the annular locking protrusion and the annular groove achieves precise positioning and stable connection between the rotating base and the mounting base through the mechanical limiting principle, ensuring that the rotating base maintains coaxiality with the mounting base during 360° rotation, thereby maintaining the accuracy of the support angle. The annular structure design maximizes the contact area between the rotating base and the mounting base, dispersing the stress generated during rotation and avoiding structural wear or fracture caused by local stress concentration. From a manufacturing process perspective, this structure can be manufactured with high precision through injection molding or precision machining, ensuring the consistency and reliability of mass production.

[0037] Preferably, the mounting base 1 is provided with a toothed ring 13, and the rotating base 2 is provided with a striking pin 22, which meshes with the toothed ring 13. This design not only ensures the stability and durability of the magnetic support ring, but also provides users with unique auditory and tactile feedback with each engagement of the striking pin and the toothed ring, as if incorporating the fun of operating a mechanical toy into the process of supporting the phone, greatly enriching the user experience.

[0038] Preferably, the teeth of the toothed ring 13 are arc-shaped. The arc-shaped teeth better adapt to the shape and movement trajectory of the impact pin, resulting in smoother and tighter meshing. This design not only reduces noise and wear caused by inaccurate meshing but also improves the service life and reliability of the magnetic support ring.

[0039] Preferably, the mounting base 1 is made of polycarbonate. Polycarbonate has excellent mechanical properties, and its impact resistance is much higher than that of ordinary plastics. It can effectively resist the impact force generated by drops or collisions during use, protecting the internal magnetic components and rotating structure from damage. The high transparency and dyeability of PC material allow the mounting base to achieve diverse appearance designs while maintaining structural strength, meeting users' personalized aesthetic needs. The lightweight nature of polycarbonate significantly reduces the overall weight of the magnetic support ring, avoiding fatigue in holding the phone or the heavy load on the magnetic car mount caused by excessive weight.

[0040] Preferably, the rotating base 2 and the support 3 are made of aluminum alloy. Aluminum alloy possesses high strength and low density, significantly reducing product weight while ensuring the load-bearing capacity of the rotating base and support. This allows the magnetic support ring to provide stable support without significantly affecting the overall center of gravity of the phone, improving user comfort during grip and operation. The excellent thermal conductivity of aluminum alloy quickly dissipates heat generated during magnetic attraction, preventing performance degradation of the magnets or damage to electronic components due to localized overheating, making it particularly suitable for high-power applications such as wireless charging. Furthermore, the aluminum alloy surface can be anodized to form a dense oxide film, giving the product wear-resistant, corrosion-resistant, and fingerprint-resistant properties, while also providing a wide range of color options, enhancing the product's texture and durability.

[0041] Example 2

[0042] This embodiment provides a mobile phone case, including a housing 5 and a magnetic support ring as described in Embodiment 1. The back of the housing 5 has a mounting groove 51. The bottom of the mounting base 1 of the magnetic support ring is fixedly connected to the mounting groove 51 by adhesive, thus connecting the magnetic support ring and the housing. The magnetic support ring is directly integrated into the mobile phone case, forming an integrated design. This design not only reduces additional accessories but also makes it simpler and more convenient to use. Users no longer need to purchase a separate magnetic support ring and install it on their phone; instead, they can directly choose a mobile phone case with support functions to enjoy both phone protection and support simultaneously. Preferably, the housing material is PC or acrylic. In this embodiment, PC is used. Choosing PC or acrylic as the housing material provides high strength and durability, lightweight design, good transparency and appearance, as well as good processing performance and plasticity.
