The following is an example to illustrate the implementation of the above magnetic component, but not limited to this.

For example, the first magnetic ring 11 may be one, two or more, and may be fixed to the first magnetic disk 1 by a non-magnetic material. Here, two magnetic rings are taken as an example, but not limited thereto. For example, the first magnetic disk 1 may have a first outer magnetic ring 11a and a first inner magnetic ring 11b. The plurality of first outer magnetic poles 111, 112 and the plurality of first inner magnetic poles 111', 112' of the first inner magnetic ring 11b can be distributed in a plurality of equiangularly separated first fan-shaped regions V1, as shown in FIG. 1 As shown, taking a quadrupole magnetic ring as an example, there are four first sector regions V1 with a 90-degree angle, one of the first sector regions V1 has the first outer magnetic pole 111 and the first inner magnetic pole 111', and the other first The fan-shaped region V1 has the first outer magnetic pole 112 and the first inner magnetic pole 112'; on the other hand, the second magnetic disk 3 may have a second outer magnetic ring 31a and a second inner magnetic ring 31b, the second outer magnetic ring The second outer magnetic poles 311 and 312 of the magnetic ring 31 a and the second inner magnetic poles 311 ′ and 312 ′ of the second inner magnetic ring 31 b can be distributed in the second sector V2 equiangularly separated, As shown in FIGS. 1 and 2, taking a quadrupole magnetic ring as an example, there are four second sector regions V2 with a 90-degree angle, one of the second sector regions V2 has the second outer magnetic pole 311 and the second inner magnetic pole 311 ', the second outer magnetic pole 312 and the second inner magnetic pole 312' are located in another second sector V2.

In this way, when the first magnetic ring 11 and the second magnetic ring 31 are relatively pivoted, if the polarities of the closest magnetic poles between the first magnetic ring 11 and the second magnetic ring 31 are opposite, A magnetic attraction force can be generated, and if the polarities of the closest magnetic poles between the first magnetic ring 11 and the second magnetic ring 31 are the same, a magnetic repulsion force can be generated to attract or separate two objects.

Optionally, in an embodiment, the polarities of the first outer magnetic poles 111, 112 and the first inner magnetic poles 111', 112' in each first sector are the same, for example: the polarities of 111 and 111' Same, the polarities of 112 and 112' are the same; on the other hand, the polarities of the second outer magnetic poles 311, 312 and the second inner magnetic poles 311', 312' in each second sector are the same, for example: 311 and The polarities of 311' are the same, and the polarities of 312 and 312' are the same. In this way, the effect of enhancing the magnetic force can be achieved, and compared with the entire first fan-shaped region filled with magnetic pole material, the magnetic pole area that fails to effectively generate magnetic attraction/repulsion when the disk rotates can be reduced, which can further improve the installation of magnetic pole material The ease of use can further reduce the cost of arranging the magnetic poles.

Alternatively, in an embodiment, the polarities of the first outer magnetic poles 111, 112 in each first sector are opposite to the polarities of the first inner magnetic poles 111', 112', in each second sector The second outer magnetic poles 311, 312 have opposite polarities to the second inner magnetic poles 311', 312'.

In one embodiment, the two side edges of the single magnetic pole (such as 111 or 112) of the first magnetic ring 11 and a center of the convex shaft 12 form a magnetic pole angle A1, and one of the second holes 32 The two lines connecting the center and the two triggering limit portions 22a and 22b form a limit angle A2. A ratio of the limit angle A2 and the pole angle A1 is between 1 and 1.2, for example: For example, the angle A1 of each pole is about 90 degrees, and the limit angle A2 can be between 90 and 108 degrees (°), for example: 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, and 108 degrees, etc., so that one of the magnetic poles of the first magnetic ring 11 (such as 111 or 112) can be completely accommodated in the second switch Between the moving limit parts 22a and 22b.

Thereby, when the pulling portion 33 is pulled from the side close to the pulling limit portion 22a to the side close to the pulling limit portion 22b, the first magnetic ring 11 and the second Complete magnetic force conversion occurs between the magnetic rings 31, for example: the first magnetic ring 11 and the second magnetic ring 31 gradually change from generating the maximum magnetic attraction force to generating the maximum magnetic repulsion force, or, from generating the maximum magnetic repulsion force To generate maximum magnetic attraction.

In one embodiment of the present invention, as shown in FIG. 1, the two pulling limit portions 22a and 22b of the spacer 2 can be a first stopper extending from the spacer 2 along an axial direction (as shown in FIG. 22a) and a second stopper (22b shown in the figure) are formed. The first stopper and the second stopper can be formed into a columnar shape or a sheet shape according to actual needs to limit the pulling portion The movable range of 33, and at the same time, the position of the spacer 2 around the first hole 21 and the two pulling limit portions 22a, 22b can jointly form a placement space for placing the second magnetic disk 3.

Thereby, when the second hole 32 is pivotally combined with the convex shaft 12, if the second magnetic disk 3 rotates relative to the first magnetic disk 1, the side wall 23 can limit and guide the second magnetic disk 3 In addition to facilitating the insertion of the second magnetic disk 3 into the spacer 2, the pulling effect can also prevent the convex shaft 12 from being subjected to excessive torsion and breaking when the second magnetic disk 3 is pulled, so as to prolong the life of the product.

In an embodiment, there is a first distance D1 between any two adjacent magnetic poles (such as 111 and 112) of the first magnetic ring 11, and a first distance between any two adjacent magnetic poles of the second magnetic ring 31 Two pitches D2, the distance between the first pitch D1 and the distance between the second pitch D2 may be between 2 and 10 millimeters (mm), for example: 2, 3, 4, 5, 6, 7, 8, 9, 10mm etc. Thereby, the polar strengths of the two adjacent magnetic poles (such as S pole and N pole) of the first magnetic ring 11 and the second magnetic ring 31 can have an inversion transition area. When magnetic force conversion occurs between the magnetic rings 31 (for example, the suction force is converted into a repulsive force, or the repulsive force is converted into a suction force), the magnetic force conversion process can be smoothly performed to avoid resistance or vibration when the pulling portion is pulled due to a sudden change in polarity strength.

In an embodiment, the magnetic poles (such as 111 and 112) of the first magnetic ring 11 may be discrete first magnetic members, for example, NdFeB magnets magnetized into N and S poles, respectively, The first magnetic disk 1 is provided with a plurality of first limiting grooves (such as 13a, 13b), for example: made of plastic, the shape of the first limiting groove can correspond to the shape of the first magnetic member, so that the number The first limiting grooves can be used to accommodate the first magnetic members; on the other hand, the magnetic poles (such as 311, 312) of the second magnetic ring 31 can be discrete second magnetic members, for example : Samarium cobalt magnets magnetized into S and N poles, respectively, the second magnetic disk 3 is provided with several second limiting grooves (such as 34a, 34b), for example: the second limiting groove is made of plastic The shape of can correspond to the shape of the second magnetic member, so that the second limiting grooves can be used to accommodate the second magnetic members.

The first magnetic disk 1 may be provided with a plurality of first locking portions 14 for fixing to the first object W with screws to enhance the fixing strength; the second magnetic disk 3 Can face a second object T (such as a table, etc.), and the second magnetic disk 3 and the spacer 2 can be combined with each other, the spacer 2 can fix the second object T, for example: the spacer 2 can be convex A spacer 24 is used to fix the second object T with screws to enhance the fixing strength, and the second magnetic disk 3 is interposed between the second object T and the spacer 2 so that the first The pulling portion 33 of the second magnetic disk 3 can be pulled between the two pulling limit portions 22a, 22b. When the first magnetic disk 1 and the second magnetic disk 3 are aligned with each other, the user can pull the The portion 33 is pulled from a position beside one of the two pulling limit portions 22a, 22b to a position beside the other of the two pulling limit portions 22a, 22b, for example: A magnetic attraction force is generated between the first magnetic disk 1, for example, a forward pulling force of 5 kg and a lateral pulling force of 1.5 kg, so that the first object W and the second object T are attracted to each other and are tightly connected; otherwise, the A magnetic repulsive force is generated between the second magnetic disk 3 and the first magnetic disk 1, so that the first object W and the second object T repel each other and bounce off.

It should be understood that, as shown in FIG. 3, the above-mentioned embodiment of the magnetic attraction assembly can also be applied to fix other objects, in particular, it can be applied to be fixed and placed in a general indoor space and can be selectively opened or Closed small and medium-sized objects, for example, the magnetic component can be fixed on door panels, door frames, windows, window frames, walls, furniture, home appliances or electronic equipment for use.
