[0001] The present invention relates to the technical field of magnetic buckles, and in particular to a Halbach array magnetic ring buckle device applied to clothing. Background Art

[0002] In the current popular trend, young people like to decorate their clothes with some objects that are beautiful, playable and practical, such as plush dolls, electronic devices, soft rubber toys, etc. Existing connection methods such as pins, snaps, Velcro, sewing, etc. are either inconvenient to disassemble and have a poor user experience, or have a cheap feel and are not aesthetically pleasing. Existing magnetic buttons are basically composed of two flat magnets with different polarities. They have traditional shapes, hard materials, single forms, insufficient magnetic force, difficulty in bearing weight or difficulty in convenient disassembly. These factors cannot meet the demand for adding playable and practical objects to clothing. Due to insufficient magnetic force, the connected objects are easily fallen off during user movement, resulting in a poor user experience and difficulty in handling clothing washing, ironing and other needs.

[0003] Summary of the Invention

[0004] In response to the defects in the existing technology, the present invention provides a Halbach array magnetic ring buckle device for use on clothing, which can more easily, conveniently, beautifully and firmly decorate playable, practical and aesthetically pleasing objects on clothing, while being easy to disassemble without affecting the daily care of the clothing.

Each of the magnetic buckle A and magnetic buckle B includes a protective cover, a magnetic ring, and a supporting bottom cover. The protective cover and the supporting bottom cover together form a closed chamber for accommodating and positioning the magnetic ring. The magnetic ring is formed into a circular ring shape by a plurality of arc-shaped unit magnets arranged in a Halbach array.

[0007] The magnetic buckle A and the magnetic buckle B both have stronger magnetic force on the side away from the supporting bottom cover, and can be magnetically attracted to each other.

[0008] Preferably, each of the magnet rings comprises 12 unit magnets which are sequentially bonded end to end or magnetically attracted, and the magnetic pole directions of the unit magnets are sequentially rotated by 90°.

[0009] Preferably, the protective cover has an annular protrusion, and the annular protrusion is completely matched with the magnet ring.

[0010] Preferably, the bottom edge of the protective cover has an inward chamfer, and the inward chamfer is used to cover the outer edge of the support bottom cover, and the contact surface of the support bottom cover and the protective cover are bonded.

[0011] Preferably, the material of the protective cover is silicone, and the material of the supporting bottom cover is PA66 nylon glass fiber.

[0012] Preferably, when the side of the magnetic buckle A away from its supporting bottom cover is attracted to the side of the magnetic buckle B away from its supporting bottom cover, the distance between the side of the magnetic ring of the magnetic buckle A away from its supporting bottom cover and the side of the magnetic ring of the magnetic buckle B away from its supporting bottom cover does not exceed 1 mm.

[0013] The beneficial effects of the present invention are embodied in:

[0014] (1) In the Halbach array magnetic ring buckle device for clothing provided by the present invention, both the magnetic buckle A and the magnetic buckle B adopt the Halbach array magnetic structure, which achieves a more uniform and powerful magnetic force distribution, increases the adsorption force of the magnetic buckle, and ensures the firm connection between clothing and decorations. In addition, a strong magnetic attraction is generated only when the magnetic buckle A and the magnetic buckle B are aligned. Such a design provides an excellent user experience of instant connection, and the magnetic buckle A and the magnetic buckle B have excellent resistance to pulling when they are magnetically attracted to each other. They can only be relatively easily separated when pulled vertically outward. The required force is moderate, which ensures the stability of the magnetic attraction and is not easy to be dislocated, separated or fall off during the user's movement.

[0015] (2) In the Halbach array magnetic ring buckle device for clothing provided by the present invention, the protective cover and the supporting bottom cover together constitute a closed chamber for accommodating the magnetic ring and limiting its position. The protective cover has an annular protrusion that fully matches the magnetic ring and can completely cover the magnetic ring, effectively protecting the magnetic ring from external impact, damage or scratches; at the same time, the supporting bottom cover can support the magnetic ring, preventing the unit magnets of the magnetic ring from separating from each other due to instantaneous force imbalance, thereby ensuring that the structure of the overall magnetic buckle is balanced and the force is uniform;

[0016] (3) In the Halbach array magnetic ring buckle device for clothing provided by the present invention, the material of the protective cover is preferably environmentally friendly silicone, which has the characteristics of safety, gentleness and skin-friendly, and can overcome the defect that the existing magnetic buttons are difficult to have an aesthetic design; the material of the supporting bottom cover is preferably PA66 nylon glass fiber, which has high strength and rigidity, and is light and thin, providing good support and structural stability; such a design makes the magnetic ring buckle device waterproof, drop-proof, rust-proof and other characteristics, and the clothing sewn with it can be washed, dry-cleaned, dried, ironed and other actions, which solves the problem that the existing magnetic buckle is easily damaged or affects the cleaning of clothing;

[0017] (4) Although the Halbach array magnetic ring buckle device for clothing provided by the present invention is specifically designed for adsorbing decorative items on clothing, and requires that it be as light and thin as possible while maintaining a magnetic attraction of appropriate strength to meet the market needs of ordinary consumers, in some other embodiments, the size and thickness of the magnetic ring can also be adjusted to meet some special application scenarios, such as the need for special engineering technicians to carry tools, and the need to carry electronic devices such as cameras and voice recorders. In fact, by adjusting the parameters such as the size and thickness of the magnetic ring, its magnetic attraction can be increased unlimitedly to meet the special needs of various special fields.

[0031] Additionally, the term "plurality" shall mean two or more.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] This embodiment provides a Halbach array magnetic ring buckle device for clothing, including a magnetic buckle A101 and a magnetic buckle B102. The magnetic buckle A101 is used to securely connect to the clothing, and the magnetic buckle B102 is used to securely connect to a decorative object. Specifically, the magnetic buckle A101 and the clothing, and the magnetic buckle B102 and the decorative object can be secured by various connection methods, such as bonding and sewing.

[0034] Both magnetic buckle A101 and magnetic buckle B102 include a protective cover 2, a magnetic ring 1, and a supporting bottom cover 3. The protective cover 2 and the supporting bottom cover 3 together form a closed chamber for accommodating the magnetic ring 1 and limiting its position. The magnetic ring 1 is formed into a circular ring shape by a plurality of arc-shaped unit magnets 11 arranged according to a Halbach array;

[0035] The magnetic buckle A101 and the magnetic buckle B102 have stronger magnetic force on the side away from the supporting bottom cover 3, and can be magnetically attracted to each other.

[0036] In this embodiment, both the magnetic buckle A101 and the magnetic buckle B102 adopt the magnet structure of the Halbach array. A strong magnetic attraction is generated only when the magnetic buckle A101 and the magnetic buckle B102 are aligned. In addition, the two are extremely resistant to pulling in all directions when they are magnetically attracted to each other. Only when they are pulled vertically outward can they be relatively easily combined and separated with moderate force. This special magnetic attraction property creates an excellent experience of instant fit, easy removal, and the attachment will not fall off even during strenuous exercise. It can fully meet the needs of attaching things such as wool to clothing. In this embodiment, the closed chamber formed by the protective cover 2 and the supporting bottom cover 3 can protect the magnetic ring 1 and isolate it from the outside, thereby extending its service life. On the other hand, the supporting bottom cover 3 can support the magnetic ring 1 to prevent the unit magnets 11 of the magnetic ring 1 from separating from each other due to instantaneous force imbalance, thereby affecting the magnetic force of the magnetic ring 1, so that the structure of the overall magnetic buckle is balanced and the force is evenly distributed, and there will be no problem of the unit magnets 11 suddenly breaking off when pulled by external force.

[0037] In this embodiment, each magnetic ring 1 includes 12 unit magnets 11 that are bonded or magnetically attracted end to end, and the magnetic pole directions of the unit magnets 11 are arranged in sequence with a rotation of 90°. Such a design can achieve a more uniform and powerful magnetic distribution, increase the adsorption force of the magnetic buckle, and ensure a firm connection between clothing and decorations.

[0038] In this embodiment, the protective cover 2 has an annular protrusion 21, which is completely matched with the magnet ring 1. By setting the annular protrusion 21 and cooperating with the supporting bottom cover 3, the magnet ring 1 can be completely covered, effectively protecting the magnet ring 1 from external impact, damage or scratching, and at the same time making the magnet ring 1 not easily deformed, ensuring that adjacent unit magnets 11 are not easily separated; the bottom edge of the protective cover 2 has an inward chamfer, which is used to cover the outer edge of the supporting bottom cover 3, and the contact surface of the supporting bottom cover 3 and the protective cover 2 are bonded. This design makes the magnet ring buckle device completely waterproof, drop-proof and rust-proof, so that the clothing sewn with it can be completely washed, dry-cleaned, dried, ironed, etc., solving the problems of existing magnetic buttons with exposed magnets or complex structures that cannot be washed, dry-cleaned or ironed.

[0039] In this embodiment, the material of the protective cover 2 is preferably environmentally friendly silicone, which is safe, gentle, and skin-friendly. It has a certain flexibility when sewn and glued on clothes, and the shape, color, and design can be diversified, which can overcome the defect that the existing magnetic buttons are difficult to have an aesthetic design. The material of the supporting bottom cover 3 is PA66 nylon glass fiber, which has high strength and rigidity. At the same time, the material is relatively light and thin, and can provide good support and structural stability.

[0040] Due to the special properties of magnets, the magnetic attraction will be weakened exponentially every time the distance between the attracting magnets exceeds 0.1mm, until it completely disappears at the critical point. Therefore, in this embodiment, when the side of the magnetic buckle A101 away from its supporting bottom cover 3 and the side of the magnetic buckle B102 away from its supporting bottom cover 3 are attracted, the distance between the side of the magnetic ring 1 of the magnetic buckle A101 away from its supporting bottom cover 3 and the side of the magnetic ring 1 of the magnetic buckle B102 away from its supporting bottom cover 3 does not exceed 1mm. When sewing or gluing on clothing, there is almost no sense of foreign matter, and the form is beautiful.

[0041] It should be noted that while the Halbach array magnetic ring buckle device provided in this embodiment is specifically designed for attaching decorative items to clothing, requiring it to be as light and thin as possible while maintaining an appropriate magnetic attraction strength to meet the market needs of ordinary consumers, in other embodiments, the size and thickness of the magnetic ring 1 can be adjusted to meet specific application scenarios, such as the need for special engineering technicians to carry tools or the need to carry electronic devices such as cameras and voice recorders. In fact, by adjusting parameters such as the size and thickness of the magnetic ring 1, its magnetic attraction can be increased infinitely to meet the special needs of various specialized fields.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
