Referring to fig. 2 and 3, the magnetic attraction ring assembly 200 includes a housing 210, a plurality of first magnetic members 220 and a plurality of second magnetic members 230, the plurality of first magnetic members 220 and the plurality of second magnetic members 230 are arranged in the housing 210 along a same circumferential direction and are spaced from each other, N poles and S poles of the first magnetic members 220 and the second magnetic members 230 are distributed along an axial direction, the N pole of the first magnetic member 220 is abutted to the S pole of the second magnetic member 230, and the S pole of the first magnetic member 220 is abutted to the N pole of the second magnetic member 230. Since the N-pole and the S-pole of the first magnetic member 220 and the second magnetic member 230 are distributed along the axial direction, the magnetic pole distribution directions of the first magnetic member 220 and the second magnetic member 230 are parallel to each other.

The plurality of the first magnetic members 220 and the plurality of the second magnetic members 230 are arranged in the housing 210 along the same circumferential direction and are spaced from each other, that is, the first magnetic members 220 and the plurality of the second magnetic members 230 are arranged in the housing 210 along the same circumferential direction according to the sequence of "the first magnetic members 220 to the second magnetic members 230 to the first magnetic members 220 to the second magnetic members 230", and the number of the first magnetic members 220 is the same as that of the second magnetic members 230.

The N poles and S poles of the first magnetic member 220 and the second magnetic member 230 are distributed along the axial direction, the N pole of the first magnetic member 220 is butted with the S pole of the second magnetic member 230, the S pole of the first magnetic member 220 is butted with the N pole of the second magnetic member 230, at this time, the plurality of first magnetic members 220 and the plurality of second magnetic members 230 are arranged to form a circular ring shape, the circular ring shape encloses a wireless charging area 250, and during assembly, the wireless charging induction coil can be arranged (or corresponds to) in the wireless charging area 250. Wherein, the diameter of the wireless charging area 250 may be larger than the diameter of the wireless charging induction coil.

Taking fig. 3 as an example, the upper surface of the first magnetic member 220 may be an N pole, the lower surface of the first magnetic member 220 is an S pole, the upper surface of the second magnetic member 230 is an S pole, and the lower surface of the second magnetic member 230 is an N pole. The N pole of the first magnetic member 220 is butted with the S pole of the second magnetic member 230, and the S pole of the first magnetic member 220 is butted with the N pole of the second magnetic member 230, so that the magnetic force lines 240 are intensively distributed between any two adjacent first magnetic members 220 and second magnetic members 230, the coverage area of the magnetic field is small, that is, the magnetic force lines 240 entering the wireless charging area are small, the interference to the magnetic induction lines 300 of the induction coil during wireless charging can be ignored, and the influence on the wireless charging of the electronic device is avoided.

In this embodiment, the magnetic attraction ring assembly 200 can be attached to the rear cover of an electronic device such as a mobile phone, a tablet personal computer, a vehicle traveling data recorder, or the protective shell of the electronic device, and the magnetic attraction force of the first magnetic part 220 and the second magnetic part 230 can fix the electronic device on a fixed object such as a bracket quickly. Compare in single magnetic part, magnetism slip ring subassembly 200 includes a plurality of first magnetic parts 220 and a plurality of second magnetic parts 230, has increased the quantity of magnetic part, and then has strengthened the effect of magnetism, can be with electronic equipment adsorbed more firmly. Because magnetic suction ring subassembly 200 can not influence electronic equipment's wireless function of charging, consequently magnetic suction ring subassembly 200 can paste for a long time and cover on electronic equipment or electronic equipment protective housing, also need not to dismantle convenient to use when wireless charging.

As an example, the number of the first magnetic members 220 and the second magnetic members 230 is eight, and the eight first magnetic members 220 and the eight second magnetic members 230 are spaced apart from each other. Of course, the number of the first magnetic member 220 and the second magnetic member 230 is not particularly limited in the embodiments of the present application, and those skilled in the art can select the number of the first magnetic member 220 and the second magnetic member 230 according to actual needs, and as the number of the magnetic members increases, the magnetic attraction force of the magnetic attraction ring assembly 200 can be increased to a certain extent.

In this embodiment, the first magnetic member 220 and the second magnetic member 230 are both permanent magnets. As an example, the first and second magnetic members 220 and 230 may be bonded permanent magnets made of a mixture of a rubber, plastic, or the like binder and a magnetic material, such as bonded neodymium iron boron magnets, bonded ferrite magnets, or the like.

In some embodiments, the plurality of first magnetic members 220 and the plurality of second magnetic members 230 may be attracted to each other by a magnetic attraction force to form an integral structure. Of course, the plurality of first magnetic members 220 and the plurality of second magnetic members 230 may be bonded together by an adhesive to form an integrated structure, so as to enhance the structural stability between the first magnetic members 220 and the second magnetic members 230. The radial cross section of the first magnetic member 220 and the second magnetic member 230 may be sector-ring-shaped, so that the plurality of first magnetic members 220 and the plurality of second magnetic members 230 may be connected to form a closed ring-shaped structure, and it may be ensured that the magnetic flux lines 230 are intensively distributed between any adjacent first magnetic members 220 and second magnetic members 230.

The central angles of the first magnetic member 220 and the second magnetic member 230 may be equal, so that the first magnetic member 220 and the second magnetic member 230 have more regular shape design and are convenient to process and manufacture. When the circle center angles of the first and second magnetic members 220 and 230 are equal, the circle center angles of the first and second magnetic members 220 and 230 are inversely proportional to the number of the magnetic members, and the larger the number is, the smaller the circle center angles of the first and second magnetic members 220 and 230 are. For example, when the number of the first and second magnetic members 220 and 230 is two, the central angles of the first and second magnetic members 220 and 230 are both equal to 90 °. When the number of the first and second magnetic members 220 and 230 is three, the central angles of the first and second magnetic members 220 and 230 are equal to 60 °.

In some embodiments, the central angles of the first and second magnetic members 220 and 230 may also be different. For example, when the number of the first magnetic member 220 and the second magnetic member 230 is two, the central angle of the first magnetic member 220 may be equal to 120 °, and the central angle of the second magnetic member 230 may be equal to 60 °.

The thicknesses of the N poles and the S poles of the first magnetic member 220 and the second magnetic member 230 are equal, so that the N pole of the first magnetic member 220 and the S pole of the second magnetic member 230 are completely overlapped and butted, and the S pole of the first magnetic member 220 and the N pole of the second magnetic member 230 are completely overlapped and butted.

In this embodiment, the central angles of the first magnetic member 220 and the second magnetic member 230 may be smaller than or equal to the set angle, so as to increase the number of the first magnetic member 220 and the second magnetic member 230, ensure that the magnetic attraction ring assembly 200 has a sufficiently large magnetic attraction force, and make the coverage of the magnetic force lines smaller. As an example, the central angle of the first and second magnetic members 220 and 230 is less than or equal to 30 °, such as 30 °, 15 °, 10 °, 5 °, and so on.
