[0034] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0036] Embodiments of this application provide a magnetic finger ring, comprising: a flexible magnet, a flexible layer, and a flexible finger ring. The flexible magnet is used for magnetic attraction. The flexible layer encapsulates the flexible magnet. The flexible finger ring is integrally formed with the flexible layer. The flexible finger ring is located at the end of the flexible layer opposite to the magnet. The connection between the flexible finger ring and the flexible layer forms a finger ring insertion area. When a user's finger is located in the finger ring insertion area, one side of the user's finger contacts the flexible finger ring, and the opposite side of the user's finger adheres to the flexible layer, with the end opposite the flexible layer and opposite to the flexible finger ring being the magnetic attraction surface.

[0037] The magnetic ring provided above provides magnetic adsorption function through a flexible magnet. The flexible layer wraps around the magnet to buffer impact, protect the magnet and improve wearing comfort. The flexible ring and the flexible layer are integrally formed to form the ring interlocking area, so that the finger fits naturally and the pressure is distributed. At the same time, the magnetic surface is exposed on the other end of the flexible layer to achieve stable adsorption.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please see Figures 1-6 The embodiments of this application provide a magnetic finger ring 100, including: a flexible magnet 10, a flexible layer 20 and a flexible finger ring 30.

[0040] A flexible magnet 10 is used for magnetic attraction. The flexible layer 20 encapsulates the flexible magnet. A flexible ring 30 is integrally formed with the flexible layer 20. The flexible ring 30 is located at the end of the flexible layer 20 away from the magnet. A ring insertion area 2030 is formed at the connection between the flexible ring 30 and the flexible layer 20. When the user's finger is located in the ring insertion area 2030, one side of the user's finger is in contact with the flexible ring 30, and the opposite side of the user's finger is in contact with the flexible layer 20, with the other end of the flexible layer 20 away from the flexible ring 30 being the magnetic attraction surface 40.

[0041] Specifically, the magnetic ring 100 includes a flexible magnet 10, which serves as the core component of the magnetic attraction function of this device and is used to attract to ferrous or iron-containing metal surfaces, such as magnetic brackets, desktops, walls, or vehicle bases.

[0042] Preferably, the flexible magnet 10 is prepared by compression molding from 4% silicone, 16% expander, and 80% neodymium iron boron powder by volume percentage. Neodymium iron boron powder is the main source of magnetism, silicone imparts flexibility, and the expander adjusts the magnet density and processing performance.

[0043] The flexible magnet 10 can bend or deform locally with the fingers, avoiding the breakage problem of rigid magnets when impacted or bent. The flexible magnet 10 provides reliable magnetic force to adhere to a metal carrier, achieving stable support. The flexibility of the flexible magnet 10 allows it to be embedded in a flexible structure, improving the overall wearing experience.

[0044] The flexible layer 20 encapsulates the magnet, providing protection, structural integration, and flexible connection. The flexible layer 20 can be integrally molded from silicone, TPU (thermoplastic polyurethane elastomer), or TPE material, ensuring a strong bond with the flexible magnet 10 and preventing delamination. Injection molding can be used to achieve a seamless connection between the flexible layer 20 and the magnet, improving structural stability and aesthetic integrity.

[0045] The flexible layer 20 acts as a cushion to prevent impact and avoid direct force that could cause the magnet to break. This makes the overall product more flexible and bendable, improving wearing comfort. The coated surface of the magnet is not exposed, preventing wear or oxidation that could cause demagnetization.

[0046] The magnetic finger ring 100 also includes a flexible finger ring 30, which is located at the end of the flexible layer 20 away from the magnet. The flexible finger ring 30 and the flexible layer 20 are integrally formed, and a finger ring insertion area 2030 for inserting a finger is formed in the connection area between the two.

[0047] The flexible ring 30 can be molded simultaneously with the flexible layer 20 using silicone or TPU, or a seamless, one-piece structure can be achieved through joint injection molding. It is ring-shaped, providing good resilience and skin fit. The ring insertion area 2030 is the area formed between the ring and the flexible layer 20, allowing the user to pass their finger through this area and naturally hold it between the ring and the flexible layer 20.

[0048] The flexible ring 30 and the flexible layer 20 are integrally molded to improve overall strength and prevent tearing at the connection. The ring insertion area 2030 is ergonomically designed to keep the finger in a stable clamping state and reduce local pressure.

[0049] The snap-on design makes it easy to assemble and disassemble, allowing for quick removal of the ring when not in use. The flexible material conforms well to the skin, preventing pressure marks or discomfort even after prolonged wear.

[0050] When worn, the user's finger is positioned in the ring insertion area 2030, with one side in contact with the flexible ring 30 and the other side adhering to the flexible layer 20. The distal end of the flexible layer 20, i.e., the end facing away from the flexible ring 30, is a magnetic surface 40 for adhering to metal surfaces.

[0051] In use, the user inserts their finger into the ring insertion area 2030, resulting in the following force relationship: the back of the hand has a flexible ring 30 that encircles the finger, forming a fixed ring. The palm side has a flexible layer 20 that adheres to the finger, providing a basis for magnetic attraction and avoiding friction. The flexible magnet 10 exposes its magnetic surface 40, allowing it to adhere to metal surfaces such as desktops, walls, and vehicle magnetic panels.

[0052] The magnetic ring 100 is composed of a flexible magnet 10, a flexible layer 20, and a flexible ring 30. The entire magnetic ring 100 is made of flexible material, which gives it good flexibility and fit. This not only improves the comfort of wearing it and avoids finger pressure or discomfort caused by rigid materials, but also effectively resists external forces such as bending and collision in daily use, reducing the risk of breakage. At the same time, the flexible structure makes it easy to adapt to different finger sizes, enhancing stability and durability, and making it suitable for long-term repeated use.

[0053] In one specific embodiment, the flexible magnet 10 is ring-shaped.

[0054] The ring structure refers to the flexible magnet 10 being arranged in a hollow circular ring or a closed curve, with a certain inner and outer diameter, which can form an enclosing structure around the user's finger or a supporting structure with the central axis as the center.

[0055] The ring structure allows the magnetic field to be distributed in a circular pattern, providing a more uniform magnetic attraction area compared to block or sheet magnets, thus improving the adhesion stability to the magnetic base or support.

[0056] In one specific embodiment, the flexible magnet 10 includes a body 11 and a hollow portion 12. The body 11 is used for magnetic attraction. The flexible ring 30 is suspended from the end of the hollow portion 12 opposite to the magnetic attraction surface 40, and is used to reduce the weight of the flexible magnet 10.

[0057] Specifically, the body 11 of the flexible magnet 10 is a ring-shaped main body, and its main component is an elastic composite material containing magnetic particles.

[0058] The main body 11 provides the primary magnetic attraction capability for the entire flexible magnet 10. Structurally, it forms a closed ring along the circumference, with the magnetic field distributed around it, resulting in high fit and stability. The main body 11 is located on the side near the outer side of the flexible layer 20, forming the magnetic attraction surface 40, which is located away from the fingers and palm when worn by the user.

[0059] The hollow portion 12 is a hollow structure disposed inside or in a local area of ​​the flexible magnet 10, integrally formed with the body 11, and preferably in a region inside the ring body that is not filled with magnetic material. The hollow portion 12 is located on the side close to the flexible ring 30 (i.e., the non-magnetic surface 40 side) and is connected to the flexible ring 30 through a connecting portion, forming a structure in which "the flexible ring 30 is suspended in the hollow portion 12".

[0060] The hollowed-out part 12 can not only reduce the overall weight of the flexible magnet 10, but also serve as a reserved hanging area for the flexible ring 30, which facilitates the realization of the transition structure of "body 11 - hollowed-out - flexible ring 30" through the integrated molding process of flexible materials.

[0061] In one specific embodiment, the flexible ring 30 includes: a first connecting portion 31, a second connecting portion 32, and a fitting portion 33. One end of the first connecting portion 31 is connected to the flexible layer 20. One end of the second connecting portion 32 is connected to the flexible layer 20 and is symmetrically arranged with the first connecting portion 31 about its center. The fitting portion 33 is connected to the other end of the first connecting portion 31. The fitting portion 33 is also connected to the other end of the second connecting portion 32. Viewed along the height direction F1 of the magnetic ring, the first connecting portion 31, the fitting portion 33, and the second connecting portion 32 are sequentially connected to form the inner diameter of the flexible magnetic ring.

[0062] Specifically, the first connecting part 31 is a support section on one side of the flexible ring 30. One end is connected to the flexible layer 20, which serves to firmly connect the flexible ring 30 to the body 11 of the magnetic ring 100. The first connecting part 31 can be made of flexible rubber, silicone, TPU or other materials and is integrally molded with the flexible layer 20.

[0063] The second connecting part 32 is structurally symmetrical to the first connecting part 31 and is also connected to the flexible layer 20, forming a mirror structure around the center of the ring. The design of the second connecting part 32 is similar to that of the first connecting part 31, ensuring balanced force on both sides during wearing and reducing local pressure.

[0064] The fitting portion 33 connects to the free ends of the first connecting portion 31 and the second connecting portion 32, i.e., one end of the non-connecting flexible layer 20, forming the lower arc or bottom arc portion of the ring. The fitting portion 33 constitutes the part where the user's finger directly contacts the ring, and its structure is mostly arc-shaped or straight, conforming to the contour of the human finger.

[0065] In one specific embodiment, the width of the fitting portion 33 is denoted as A1, and the width of the connecting portion is denoted as A2, satisfying the following relationship:

[0066] A1 > A2.

[0067] Specifically, the fitting portion 33 is located below the flexible ring 30 and is a lateral extension connecting the two connecting portions. The fitting portion 33 is located on the back of the user's finger. The width A1 of the fitting portion 33 refers to the dimension of the fitting portion 33 in the horizontal direction, that is, perpendicular to the height direction F1 of the magnetic ring. The width A2 of the connecting portion refers to the width of the first connecting portion 31 and the second connecting portion 32, which extend from the flexible layer 20 to the fitting portion 33. Width A2 represents the lateral dimension of the connecting portion (lateral is compared with the fitting portion 33 in the same direction).

[0068] A1>A2 ensures that the lateral extension of the fitting part 33 is greater than that of the connecting part, forming a "wide bottom and narrow arm" structural layout, which is conducive to the dispersion of force, the increase of the contact surface 331 and the improvement of structural stability.

[0069] In one specific embodiment, the flexible ring 30 includes a contact surface 331 located near the flexible layer 20, and the contact surface 331 is in contact with the user's ring.

[0070] Specifically, the fitting part 33 connects the two connecting parts mentioned above, wraps around the back of the user's finger, and the inner side of the flexible ring 30 is provided with a contact surface 331. The contact surface 331 is an arc-shaped surface, made of a skin-friendly material such as silicone or TPU, and has a certain coefficient of friction. The contact surface 331 is in close contact with the skin on the back of the user's finger, ensuring that the magnetic ring 100 will not slip or rotate in the adsorbed state.

[0071] In one specific embodiment, the contact surface 331 is provided with anti-slip protrusions 332, the anti-slip protrusions 332 protrude from the contact surface 331, and the anti-slip protrusions 332 fit against the user's ring.

[0072] Specifically, multiple anti-slip protrusions 332 are formed on the contact surface 331, preferably circular or elliptical boss-like structures, with a spacing of 0.5mm to 2mm, arranged in a regular grid or naturally scattered manner. The anti-slip protrusions 332 can be made of soft silicone microparticles, rubber micro-protrusions, or one-piece molded elastic protrusions, forming point-like contact with the finger skin to increase the coefficient of friction.

[0073] Therefore, the magnetic ring 100 provided above provides magnetic adsorption function through the flexible magnet 10. The flexible layer 20 wraps the magnet to buffer impact, protect the magnet and improve wearing comfort. The flexible ring 30 and the flexible layer 20 are integrally formed to form the ring insertion area 2030, so that the finger fits naturally and the pressure is distributed. At the same time, the magnetic surface 40 is exposed on the other end of the flexible layer 20 to achieve stable adsorption.

[0074] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
