Please refer to Figures 1 and 2, the magnetic attraction assembly of the first embodiment of the present invention may include a first disk 1, a spacer 2 and a second disk 3. The first disk 1 may have at least one first disk The magnetic ring 11 and a convex shaft 12, the first magnetic ring 11 has several magnetic poles with opposite magnetic properties and alternately arranged, for example: 111 and 111' are N magnetic poles, 112, 112' are S magnetic poles, but not limited to this The spacer 2 may have a first hole 21 (such as a perforation) and two pull limiting portions 22a, 22b, the convex shaft 12 detachably passes through the first hole 21; the second disk 3 may have at least A second magnetic ring 31 and a second hole 32. The second magnetic ring 31 has several magnetic poles with opposite magnetic properties and alternately arranged. For example, 311 and 311' are N magnetic poles, and 312 and 312' are S magnetic poles, but not With this limitation, the second hole 32 (such as a blind hole or a through hole, etc.) is detachably pivotally connected to the convex shaft 12, and the second magnetic ring 31 and the first magnetic ring 11 have the same size and are spaced apart. In contrast, for example, the number and size of the magnetic poles of the second magnetic ring 31 and the first magnetic ring 11 are the same, the second magnetic disk 3 may be protrudingly provided with a flip portion 33, for example, extending outward along the second hole 32 One radially outwardly protrudes for the user to pull the second magnetic disk 3 so that the second magnetic ring 31 can pivot relative to the first magnetic ring 11, and the pull part 33 is located on the second magnetic ring. Between the movable limit parts 22a, 22b, so as to use the two pull limit parts 22a, 22b to limit the movable range of the pull part 33. The following examples illustrate the implementation of the above-mentioned magnetic attraction component, but it is not limited thereto.

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, and the first outer magnetic ring 11a 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 together in a plurality of equiangularly separated first sector regions V1, as shown in Figure 1. As shown, taking a four-pole magnetic ring as an example, there are four first sector regions V1 with an angle of 90 degrees. 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 sector V1 The sector V1 has the first outer magnetic pole 112 and the first inner magnetic pole 112'; on the other hand, the second disk 3 may have a second outer magnetic ring 31a and a second inner magnetic ring 31b. The plurality of second outer magnetic poles 311, 312 of the magnetic ring 31a and the plurality of second inner magnetic poles 311', 312' of the second inner magnetic ring 31b may be distributed together in a plurality of equiangularly separated second sectors V2, As shown in Figures 1 and 2, taking a four-pole magnetic ring as an example, there are four second sector regions V2 with an angle of 90 degrees. One of the second sector regions V2 has the second outer magnetic pole 311 and the second inner magnetic pole 311. ', there are the second outer magnetic pole 312 and the second inner magnetic pole 312' in another second sector V2.

Therefore, 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. 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, 112 and 112' have the same polarity; on the other hand, the second outer magnetic poles 311, 312 and the second inner magnetic poles 311', 312' in each second sector have the same polarity, for example: 311 and 311' has the same polarity, and 312 and 312' have the same polarity. By this, the effect of enhancing the magnetic force can be achieved, and compared with the entire first sector area being filled with magnetic pole material, the magnetic pole area that fails to effectively generate magnetic attraction/repulsion when the disk is rotated can be reduced, and the mounting magnetic pole material can be improved It is easy to reduce the cost of magnetic pole arrangement.

Alternatively, 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 opposite, and in each second sector The second outer magnetic poles 311 and 312 and the second inner magnetic poles 311' and 312' have opposite polarities.

In one embodiment, the two side edges of a 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 included angle A1, and one of the second holes 32 The two connecting lines between the center and the two pull limit parts 22a, 22b form a limit included angle A2, and a ratio of the limit included angle A2 to the magnetic pole included angle A1 is between 1 and 1.2, for example: For example, the included angle A1 of each magnetic pole is about 90 degrees, and the limit included angle A2 can be between 90 and 108 degrees (°), such as: 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 poles of the first magnetic ring 11 (such as 111 or 112) can be completely accommodated in the two plates Between the movable limiter 22a, 22b.

Thereby, when the pull portion 33 is pulled from the side close to the pull limit portion 22a to the side close to the pull limit portion 22b, the first magnetic ring 11 and the second A 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 gradually changing from generating the maximum magnetic repulsion force To produce the maximum magnetic attraction.

In an embodiment of the present invention, as shown in Figure 1, the two triggering limiting portions 22a, 22b of the spacer 2 can be formed by a first stopper extending along an axial direction of the spacer 2 (as shown in Figure 22a) as shown and a second stopper (22b as shown in the figure) are formed. The first stopper and the second stopper can be formed into a column or sheet shape according to actual needs to limit the flip part 33. At the same time, the part of the spacer 2 around the first hole 21 and the two pull limiting portions 22a, 22b can jointly form a placement space for placing the second disk 3.

In one embodiment, as shown in Figure 1, the first stopper (22a as shown in the figure) extends from a side wall 23 to the second stopper (22b as shown in the figure) in a circumferential direction, For example, the side wall 23 can be formed by continuously distributed materials or discretely distributed blocks to form an arc-shaped retaining wall. Thereby, when the second hole 32 is pivotally connected to the convex shaft 12, if the second disk 3 rotates relative to the first disk 1, the side wall 23 can limit and guide the second disk 3 The effect is that in addition to facilitating the insertion of the second magnetic disk 3 into the spacer 2, it can also prevent the protruding shaft 12 from being broken due to excessive torque when the second magnetic disk 3 is pulled, so as to prolong the product life.

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 there is a first distance between any two adjacent magnetic poles of the second magnetic ring 31. Two spacing D2, the distance between the first spacing D1 and the second spacing D2 can be between 2 to 10 millimeters (mm), for example: 2, 3, 4, 5, 6, 7, 8, 9, 10 mm etc. Thereby, the polarities of the two adjacent magnetic poles (such as the S pole and the N pole) of the first magnetic ring 11 and the second magnetic ring 31 can have a reversal transition region. When the magnetic force conversion occurs between the magnetic rings 31 (such as attracting force to repulsive force, or repulsive force to attracting force), the magnetic force conversion process can be performed smoothly, and the sudden change of polarity intensity can avoid the resistance or vibration when the flipping part is flipped.

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

Please refer to Figures 2 and 3, when the magnetic attraction assembly of the above embodiment of the present invention is used, the first disk 1 can be fixed to a first object W (such as a wall, etc.), for example, adhesive or screw can be used. In one embodiment, the first 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 disk 3 It can face a second object T (such as a table, etc.), and the second 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 protruded. Two spaced locking portions 24 are used to fix the second object T with screws to enhance the fixing strength, and the second disk 3 is sandwiched between the second object T and the spacer 2 to make the second object T The flip part 33 of the two disks 3 can be flipped between the two flip limit parts 22a, 22b. When the first disk 1 and the second disk 3 are aligned with each other, the user can flip The portion 33 is moved from a position beside one of the two pull limit portions 22a, 22b to a position beside the other of the two pull limit portions 22a, 22b, for example: the second disk 3 can be connected to A magnetic attraction force is generated between the first magnetic disk 1, for example: a positive tension of 5 kg and a lateral tension of 1.5 kg, so that the first object W and the second object T are attracted to each other and tightly connected; otherwise, the A magnetic repulsion force is generated between the second magnetic disk 3 and the first magnetic disk 1, causing the first object W and the second object T to repel each other and bounce away.

It should be understood that, as shown in Fig. 3, the above-mentioned embodiments of the magnetic attraction assembly can also be used to fix other objects, in particular, it can be applied to fix and be placed in a general indoor space, and can be opened or opened according to usage requirements. Closed small and medium-sized objects, for example, the magnetic assembly can be selected to be fixed on door panels, door frames, windows, window frames, walls, furniture, home appliances or electronic equipment for use. In one embodiment, taking medical equipment as an example, for example, the first disk 1 can be fixed to a portable instrument (such as an oscilloscope or electrocardiograph), and the second disk 3 and the spacer 2 can be mutually In combination, the spacer 2 is fixed on a flat surface (such as a desktop or a tablet, etc.) to prevent the portable instrument from falling and being damaged. In addition, the first disk 1 and the spacer 2 can be respectively locked on a wall and a medical cart to secure the medical cart to park against the wall. In addition, it is also possible to lock the first disk 1 of several magnetic components (such as 4) on a base of a medical refrigerator, and fix the spacers 2 of the several magnetic components on the floor to fix The medical refrigerator will not be shaken (such as earthquake) and overturned, but it is not limited to this.

In addition, as shown in FIG. 4, the difference between the second embodiment of the present invention and the first embodiment mainly lies in the shape and placement of the magnetic parts on the disk. For example, the magnetic attraction component of the second embodiment may include: a first magnetic disk 4, a spacer 5, and a second magnetic disk 6. The first magnetic disk 4 may have a plurality of first magnetic stripes 41 and a convex Shaft (not shown in the figure, it can correspond to the convex shaft 12 of the first embodiment, as shown in Fig. 1), the plurality of first magnetic strips 41 are arranged equiangularly with the convex shaft as the center, for example: four A magnetic stripe 41 is separated by an angle of 90 degrees, and any two adjacent first magnetic strips 41 have different magnetic properties. For example, two adjacent first magnetic strips 41a and 41b can each have N and S magnetic poles; the spacer 5 can It has a first hole (not shown in the figure, which can correspond to the first hole 21 of the first embodiment, as shown in Figure 1) and two pull limit parts 51a, 51b (which can correspond to the first embodiment Turn the limiting parts 22a, 22b, as shown in Figure 1), the convex shaft detachably passes through the first hole; the second magnetic disk 6 may have a plurality of second magnetic strips 61 and a second hole ( The figure is not shown, it can correspond to the second hole 32 of the first embodiment, as shown in Figure 1), the second magnetic strip 61 is arranged equiangularly with the second hole as the center, and any two adjacent second The magnetism of the magnetic strip 61 is different. For example, two adjacent second magnetic strips 61a and 61b can be N and S magnetic poles, the second hole is detachably pivotally connected to the convex shaft, and the second magnetic strip 61 is connected to the The first magnetic strips 41 have the same size and are spaced opposite each other. The second magnetic disk 6 is protruded with a flip portion 62 (corresponding to the flip portion 33 of the first embodiment, as shown in Figure 1), the flip portion 62 It is located between the two pull limit parts 51a and 51b. Thereby, when the second magnetic disk 6 is pulled to rotate relative to the first magnetic disk 4, the first magnetic disk 4 and the second magnetic disk 6 can be attracted to each other by magnetic attraction or separated from each other by magnetic repulsion.

It is worth noting that in the second embodiment, as shown in FIG. 4, in the first magnetic disk 4, each first magnetic stripe 41 is adjacent to an auxiliary magnetic stripe 42, and the polarity of the auxiliary magnetic stripe 42 is The polarities of the adjacent main magnetic strips 41 are opposite. For example, the first magnetic strip 41a (such as N magnetic pole) is adjacent to the auxiliary magnetic strip 42b (such as S magnetic pole), and the first magnetic strip 41b (such as S magnetic pole) is adjacent to the auxiliary magnetic strip. 42a (such as N magnetic poles) are adjacent, the length of the auxiliary magnetic strip 42 is smaller than the length of the first magnetic strip 41, and the auxiliary magnetic strip 42 is far away from the convex axis.

Thereby, if the second magnetic stripe 61 of the second magnetic disk 6 and the first magnetic stripe 41 of the first magnetic disk 4 generate magnetic attraction force, when the second magnetic disk 6 is pivoted toward the auxiliary magnetic strip 42 (while away from When the first magnetic strip 41) moves, the auxiliary magnetic strip 42 provides the second magnetic disk 6 with a weaker magnetic force opposite to that of the first magnetic strip 41, for example: The magnetic strip 61 generates a strong magnetic attraction force, and the auxiliary magnetic strip 42 generates a weak magnetic repulsion force to the second magnetic strip 61. In this way, a smooth transition effect can be provided for the magnetic force conversion process, and the second disk 6 is prevented from being too laborious when being pulled.

In one embodiment, the extension direction of the auxiliary magnetic strip 42 and the extension direction of the first magnetic strip 41 may be different. For example, an extension line of the auxiliary magnetic strip 42 and an extension line of the first magnetic strip 41 may be different. It intersects at a center of the convex axis and forms a magnetic stripe angle A3, such as an acute angle, so that the auxiliary magnetic stripe 42 and the second magnetic stripe 61 can have the largest magnetic force acting area. Thereby, the auxiliary magnetic strip 42 can provide the largest magnetic force to the second magnetic strip 61 to provide the best smooth transition effect.

Optionally, in the second embodiment, features corresponding to the first embodiment can also be provided. For example, the two pull limit portions 51a, 51b of the spacer 5 can be moved along an axial direction by the spacer 5 An extended first stopper and a second stopper are formed; in addition, the first stopper extends from a side wall 52 in a circumferential direction to the second stopper; in addition, the first disk 4 may be provided with several second stoppers.
