SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art and providing a double-sided magnetic attraction ring suitable for mobile phones.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-sided magnetic attraction ring suitable for mobile phones, which comprises a shell, the shell is annular, an installation cavity is arranged in the shell, a first magnetic ring, a folding member and a second magnetic ring are sequentially stacked in the installation cavity, the side of the first magnetic ring and the second magnetic ring close to the folding member is a weak magnetic surface, the side of the first magnetic ring and the second magnetic ring away from the folding member is a strong magnetic surface, and an upper anti-scratch layer and a lower anti-scratch layer are respectively fixed to the upper and lower sides of the shell.

[0005] Further, the folding member is preferably a galvanized iron sheet, and the folding member completely covers the contact surface of the first magnetic ring, the second magnetic ring and the folding member.

[0006] Further, the first magnetic ring and the second magnetic ring are respectively composed of a plurality of N52 magnetic blocks arranged in a circle.

[0007] Further, the shell is made of an alloy by pressure casting.

[0008] Further, an opening part is arranged on the shell above the installation cavity, and the first magnetic ring, the folding member and the second magnetic ring are loaded into the installation cavity from the opening part.

[0009] Further, the edge of the opening part is concave to the outside, forming an upper installation groove, the outer contour of the upper anti-scratch layer matches the upper installation groove, and the upper anti-scratch layer is installed on the upper installation groove.

[0010] Further, the bottom surface of the shell is concave to the inside, forming a lower installation groove, and the lower anti-scratch layer is fixed on the lower installation groove.

[0011] Preferably, the distance between the surface of the upper anti-scratch layer and the surface of the lower anti-scratch layer is 3mm.

[0012] The beneficial effects of this utility model are as follows: both the top and bottom surfaces of the magnetic ring are strong magnetic surfaces, allowing it to be magnetically attached to ferromagnetic metal materials such as railings using one side, and to magnetically hold the phone in place with the other side (if the phone does not have a magnetic function, a magnetic ring can be installed on the phone case for adsorption). The magnetic ring can be easily removed from ferrous materials and repositioned, and can also be easily separated from the phone, making it convenient to use. In addition, by setting a refractive element to enhance the magnetic attraction of the strong magnetic surfaces of the first and second magnetic rings, the magnetic ring or the phone can be effectively prevented from falling off during magnetic attraction, increasing the stability of the magnetic ring.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example: A double-sided magnetic ring for mobile phones includes a housing 1, which is annular in shape and made of alloy die-casting, giving it high strength. The housing 1 has an internal mounting cavity 11, within which a first magnetic ring 2, a refractive element 4, and a second magnetic ring 3 are sequentially stacked. The first magnetic ring 2, the second magnetic ring 3, and the refractive element 4 are connected by an adhesive. The first magnetic ring 2, the second magnetic ring 3, and the die-cast housing 1 are also connected by an adhesive. The side of the first magnetic ring 2 and the second magnetic ring 3 closest to the refractive element 4 is a weak magnetic surface, while the side furthest from the refractive element 4 is a strong magnetic surface. The refractive element 4 shields the magnetism of the weak magnetic surface. The magnetic force is refracted onto the corresponding strong magnetic surface to enhance the magnetic attraction of the strong magnetic surface, preventing the magnetic ring or the mobile phone on the magnetic ring from falling off during use. The upper and lower anti-scratch layers 5 and 6 are respectively fixed on the upper and lower sides of the housing 1. During use, one side of the magnetic ring is attached to the surface of ferromagnetic metal materials such as railings, refrigerator doors, and iron walls, while the hand is magnetically fixed to the other side of the magnetic ring. Since both sides of the magnetic ring are magnetically fixed, the magnetic ring can be removed at any time to change its installation position and the mobile phone on the magnetic ring can be removed at any time, making it more convenient to use. Both sides of the magnetic ring are strong magnetic surfaces with strong attraction, which can effectively prevent the mobile phone or magnetic ring from falling off during the magnetic attraction process, resulting in higher reliability.

[0020] Furthermore, the refractive element 4 is preferably galvanized iron sheet. The refractive element 4 completely covers the contact surface between the first magnetic ring 2, the second magnetic ring 3 and the refractive element 4, which can better shield the magnetism of the weak magnetic surface and enhance the magnetic attraction of the strong magnetic surface.

[0021] Furthermore, the first magnetic ring 2 and the second magnetic ring 3 are respectively composed of a plurality of N52 magnetic blocks arranged in a circular pattern.

[0022] Furthermore, an opening is provided on the housing above the mounting cavity 11, through which the first magnetic ring 2, the refractive element 4, and the second magnetic ring 3 are inserted into the mounting cavity 11 for easy installation.

[0023] Furthermore, the edge of the opening is recessed outward to form an upper mounting groove 13. The outer contour of the upper anti-scratch layer 5 matches the upper mounting groove 13. The upper anti-scratch layer 5 can be installed on the upper mounting groove 13 with an adhesive. The bottom surface of the housing 1 is recessed inward to form a lower mounting groove 12. The lower anti-scratch layer 6 can be fixed on the lower mounting groove 12 with an adhesive. The upper anti-scratch layer 5 and the lower anti-scratch layer 6 can prevent the magnetic ring from scratching the mobile phone or the ferromagnetic metal surface. The upper anti-scratch layer 5 and the lower anti-scratch layer 6 can be made of silicone material.

[0024] Furthermore, the diameter of the hollow circle inside the housing 1 is preferably 43.4 mm, and the distance from the surface of the upper anti-scratch layer 5 to the surface of the lower anti-scratch layer 6 is preferably 3 mm, which can reduce the impact on the charging efficiency of the mobile phone wireless charging while maintaining strong magnetic force.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
