Detailed implementation manners

[0084] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present application without creative efforts fall within the protection scope of the present application.

[0085] In the present application, referring to "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0086] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally further includes one or more parts not listed but inherent to the product shown, or one or more parts that should be had based on the described function.

[0087] Please refer to Figures 1 to 2 , a magnetic unit 10 provided in the first embodiment of the present application includes a first magnetic member 131` and a second magnetic member 133`.

[0088] The first magnetic member 131` has a magnetization direction along the first axial direction ( Figures 1 to 2 the direction indicated by the arrow in the first magnetic member 131` in ). In other words, the first magnetic member 131` forms two opposite magnetic poles in the first axial direction, where the opposite magnetic poles refer to the N pole and the S pole. Among them, the first axial direction can be the +Z direction or the -Z direction. Subsequently, the first axial direction is taken as the +Z direction as an example.

[0089] The second magnetic member 133` has a magnetization direction along the second axial direction ( Figures 1 to 2 the direction indicated by the arrow in the second magnetic member 133` in ), and the second axial direction is opposite to the first axial direction. In other words, the second magnetic member 133` forms two opposite magnetic poles in the second axial direction. When the first axial direction is the +Z direction, the second axial direction is the -Z direction. When the first axial direction is the -Z direction, the second axial direction is the +Z direction. Subsequently, the second axial direction is taken as the -Z direction as an example.

[0090] The inner and outer sides of the magnetic unit 10 have magnetization directions along the axis and in opposite directions, respectively. Therefore, a magnetic field distribution can be formed from the first axis, radially to the second axis or from the second axis, radially to the first axis, which can not only enhance the magnetic strength on one axial side of the magnetic unit 10 and improve the magnetic adsorption reliability.

[0091] Please refer to Figure 1 , the first magnetic member 131` and the second magnetic member 133` have a spacing distance H or are in contact with each other in the radial direction. The radial direction is the X direction.

[0092] Optionally, the first magnetic member 131` and the second magnetic member 133` are two independent structures and are fixedly connected together. Optionally, the first magnetic member 131` and the second magnetic member 133` are two magnets respectively, and these two magnets are arranged along the radial direction, and the first magnetic member 131` and the second magnetic member 133` are fixedly bonded by surface-to-surface, or the end of the first magnetic member 131` and the end of the second magnetic member 133` are both fixed to the connecting member. In this way, there may be a spacing distance H between the first magnetic member 131` and the second magnetic member 133`. The present application does not make specific limitations on the spacing distance H, and the spacing distance H can be flexibly designed according to the radial width requirements of the magnetic unit.

[0093] The first magnetic member 131` and the second magnetic member 133` in this embodiment are two independent magnetizable bulk substrates. Physically, they are two substrates. These two independent magnetizable bulk substrates are magnetized along the first axis and the second axis respectively. The two independent magnetizable bulk substrates are assembled together along the radial direction.

[0094] In other words, for the radial width requirements of different magnetic units, the first magnetic member 131` and the second magnetic member 133` can be combined to form a magnetic unit. By flexibly designing the distance between the first magnetic member 131` and the second magnetic member 133`, the radial width requirements of different magnetic units can be met, with simple process, low cost and compatibility with the radial width requirements of different magnetic units.

[0095] A magnetic unit 10 provided in the first embodiment of the present application includes a first magnetic member 131` and a second magnetic member 133`. The first magnetic member 131` has a magnetization direction along the first axis; the second magnetic member 133` has a magnetization direction along the second axis; the second axis is opposite to the first axis. The first magnetic member 131` and the second magnetic member 133` have a spacing distance H or are in contact with each other in the radial direction. In this way, by designing that the magnetic unit 10 has two magnetization directions, the structure is simple and the cost is low. The first magnetic member 131` and the second magnetic member 133` are arranged at a certain gap or in contact with each other, and the distance between the first magnetic member 131` and the second magnetic member 133` can be flexibly designed, and the magnetic unit 10 has good compatibility.

[0096] Optionally, refer to Figures 2 to 5d , the magnetic unit 10 has a first magnetic surface 11 and a second magnetic surface 12 arranged opposite to each other along the axis.

[0097] Refer to Figures 2 to 5d , the first magnetic surface 11 has two magnetic poles along the radial direction. Optionally, the first magnetic surface 11 is respectively the first magnetic pole O1 of the first magnetic member 131` and the third magnetic pole O3 of the second magnetic member 133` along the radial direction.

[0098] Refer to Figures 2 to 5d , the second magnetic surface 12 has two magnetic poles along the radial direction. The second magnetic surface 12 is respectively the second magnetic pole O2 of the first magnetic member 131` and the fourth magnetic pole O4 of the second magnetic member 133` along the radial direction.

[0099] Optionally, refer to Figures 2 to 5d , the third magnetic pole O3 has the same magnetism as the second magnetic pole O2, and the third magnetic pole O3 has the opposite magnetism to the first magnetic pole O1. The fourth magnetic pole O4 is the same as the first magnetic pole O1, and the fourth magnetic pole O4 is opposite to the third magnetic pole O3. Thus, when the second magnetic surface 12 is the magnetic attracting surface, the inner side and the outer side on the second magnetic surface 12 of the magnetic unit 10 are two opposite magnetic poles, for example, the second magnetic pole O2 and the fourth magnetic pole O4. Both the second magnetic pole O2 and the fourth magnetic pole O4 can magnetically attract the magnetic unit on another device, so that the docking surfaces of the two magnetic units 10 are tightly magnetically attracted.

[0100] Among them, the first magnetic pole O1 is an N pole or an S pole. In an optional implementation manner, refer to Figure 2 , the first magnetic pole O1 and the fourth magnetic pole O4 are N poles, and the second magnetic pole O2 and the third magnetic pole O3 are S poles. In another optional implementation manner, refer to Figure 3 , the first magnetic pole O1 and the fourth magnetic pole O4 are S poles, and the second magnetic pole O2 and the third magnetic pole O3 are N poles.

[0101] This application does not specifically limit the shape of the magnetic unit 10. Optionally, the shape of the positive projection of the magnetic unit 10 in the axial direction includes but is not limited to any one of an arc, a rectangle, a triangle, a trapezoid, and a bow. In addition, the extension trajectory of the magnetic unit 10 in the plane perpendicular to the axial direction is a broken line or a curved line.

[0102] In other words, the shape of the magnetic unit 10 includes but is not limited to any one of an arc strip, a rectangular strip, a trapezoidal strip, a bow strip, a bent strip, a triangular block, and a curved strip.

[0103] This application does not specifically limit the length and width of the magnetic unit 10. When the magnetic unit 10 is in the shape of a rectangular strip, the shape of the magnetic unit 10 includes, but is not limited to, a cube or a cuboid. When the shape of the magnetic unit 10 is a cube or a cuboid, the magnetic unit 10 can be formed by cutting a long magnetic strip into multiple magnetic units 10. The magnetic units 10 prepared in this way have high processing efficiency, simple processes, and low costs.

[0104] When the magnetic unit 10 is in the shape of an arc strip, the radian of the magnetic unit 10 is not specifically limited. When the shape of the magnetic unit 10 is an arc strip, it is convenient to arrange it into a circular ring.

[0105] When the magnetic unit 10 is in the shape of a bent strip, the extension trajectory of the magnetic unit 10 can be in the shape of a V, an L, etc., so as to be easily spliced into a ring.

[0106] When the magnetic unit 10 is in the shape of a curved strip, the extension trajectory of the magnetic unit 10 can be in the shape of a C, a U, an S, etc., so as to be easily spliced into at least one ring.

[0107] The second magnetic surface 12 is a magnetic attraction surface for attracting the magnetic unit on another device. In other words, when two magnetic units 10 are magnetically attracted along the axis, the first magnetic surface 11 is on the side facing away from the magnetic unit on another device, and the second magnetic surface 12 is the surface facing the magnetic unit on another device, and it is the magnetic attraction surface for attracting the magnetic unit on another device.

[0108] Please refer to Figure 6 , the magnetic unit 10 further includes a magnetic isolation sheet 20. The magnetic isolation sheet 20 is attached to the first magnetic surface 11. The material of the magnetic isolation sheet 20 includes, but is not limited to, silicon steel or other soft magnetic materials, which play the role of reducing magnetic field divergence and realizing the pasting and fixing of the first magnetic member 131` and the second magnetic member 133`.

[0109] Optionally, please refer to Figure 7 , the magnetic unit 10 further includes an inner magnetic surface 15 and an outer magnetic surface 16 arranged opposite to each other along the radial direction. The inner magnetic surface 15 is connected between the first magnetic surface 11 and the second magnetic surface 12. The outer magnetic surface 16 is connected between the first magnetic surface 11 and the second magnetic surface 12.

[0117] Optionally, multiple magnetic units 10 are arranged in a certain pattern to form a magnetic component 13. The present application does not specifically limit the number of magnetic units 10 that make up the magnetic component 13. For example, the magnetic component 13 includes 2, or 3, or 4, or 5, or 6, or 7, or 8 magnetic units 10. For another example, please refer to Figure 8a , multiple arc-shaped magnetic units 10 surround to form a circular ring. For another example, please refer to Figure 8b , multiple rectangular bar-shaped magnetic units 10 surround to form an approximately circular ring. For another example, please refer to Figure 8c , multiple trapezoidal bar-shaped magnetic units 10 surround to form an approximately circular ring. For another example, multiple triangular block-shaped magnetic units 10 surround to form an approximately circular ring.

The magnetic poles on the outer side of each magnetic unit 10 are the same, and the magnetic poles on the inner side of each magnetic unit 10 are the same. For example, the inner sides of the magnetic component 13 are all S poles, and the outer sides of the magnetic component 13 are all N poles. In this way, the inner side of the magnetic component 13 has a strong S pole magnetism, and the outer side of the magnetic component 13 has a strong N pole magnetism.

[0119] A magnetic component 13 provided by an embodiment of the present application includes multiple magnetic units 10 as described above.

In this way, by designing the magnetic unit 10 to have two magnetization directions, the structure is simple and the cost is low. The first magnetic member 131` and the second magnetic member 133` are arranged at a certain gap or in contact with each other, and the positions between the first magnetic member 131` and the second magnetic member 133` can be flexibly designed, and the magnetic unit 10 has good compatibility. In this way, the magnetic component 13 has a simple structure, low cost, and good compatibility.

For example, please refer to Figure 9a, a plurality of magnetic units 10 and a plurality of magnetically attracted units 30 are both arranged continuously. The plurality of magnetic units 10 are arranged in an arc shape of θ°, and the plurality of magnetically attracted units 30 are arranged in an arc shape of (360° - θ°). The plurality of magnetically attracted units 30 and the plurality of magnetic units 10 are arranged to form a complete ring.

[0121] The shape and size of the magnetically attracted unit 30 are the same as those of the magnetic unit 10.

[0122] The magnetic unit 10 includes, but is not limited to, samarium-cobalt magnets, neodymium-iron-boron magnets (strong magnets), ferrite magnets, alnico magnets, iron-chromium-cobalt magnets, etc.

[0123] The material of the magnetically attracted unit 30 includes, but is not limited to, metals such as iron, cobalt, and nickel, or alloys formed by the above metals. Among them, the cost of the magnetically attracted units 30 of the same size is less than that of the magnetic units 10. Therefore, replacing a part of the magnetic units 10 with magnetically attracted units 30 and arranging them into the magnetic component 13 can ensure that the magnetic component 13 can be magnetically attracted to the paired magnetic component 13 while reducing costs.

[0124] For another example, please refer to Figure 9b , a plurality of magnetic units 10 and a plurality of magnetically attracted units 30 are both arranged discontinuously. The magnetic units 10 and the magnetically attracted units 30 are arranged alternately in a circular ring shape. Replacing a part of the magnetic units 10 with magnetically attracted units 30 and arranging them into the magnetic component 13 can ensure that the magnetic component 13 can be magnetically attracted to the paired magnetic component 13 while reducing costs. Moreover, in this embodiment, the magnetic units 10 and the magnetically attracted units 30 are arranged alternately in a circular ring shape, which not only reduces costs but also makes the magnetic force distribution of the magnetic component 13 more uniform.

[0125] Optionally, please refer to Figures 10a to 10d , a magnetic unit 10 provided in the second embodiment of the present application. The magnetic unit 10 includes an inner magnetic surface 15 and an outer magnetic surface 16 arranged opposite to each other in the radial direction, and at least one of the inner magnetic surface 15 and the outer magnetic surface 16 is a plane.

[0126] For example, please refer to Figure 10a , the inner magnetic surface 15 is a plane and the outer magnetic surface 16 is a convex arc surface, so that a circular shape is formed on the outer periphery after the plurality of magnetic units 10 are arranged. For another example, please refer to Figure 10b , the inner magnetic surface 15 is a concave arc surface and the outer magnetic surface 16 is a plane, so that a circular shape is formed on the inner periphery after the plurality of magnetic units 10 are arranged.

[0127] For another example, please refer to Figure 10c and Figure 10d, both the inner magnetic surface 15 and the outer magnetic surface 16 are flat surfaces. The magnetic unit 10 is in the shape of a rectangular strip or a trapezoidal strip. The rectangular strip includes, but is not limited to, a cube and a cuboid. When the magnetic unit 10 is in the shape of a cube or a cuboid, the magnetic unit 10 can be formed by cutting a long magnetic strip into multiple magnetic units 10. The magnetic units 10 prepared in this way have high processing efficiency, simple processes, and low costs.

[0128] In addition, the magnetic unit 10 is in the shape of a triangular block. The magnetic unit 10 can be formed by cutting a long magnetic strip into multiple magnetic units 10. The magnetic units 10 prepared in this way have high processing efficiency, simple processes, and low costs.

[0129] Please refer to Figures 11 to 13c , the magnetic unit 10 includes a first magnetic part 131, a non-magnetic part 134, and a second magnetic part 133.

[0130] Please refer to Figures 11 to 13c , the first magnetic part 131 has a magnetization direction along the first axial direction. In other words, the first magnetic part 131 forms two opposite magnetic poles in the first axial direction. Among them, the opposite magnetic poles refer to the N pole and the S pole.

[0131] Please refer to Figures 11 to 13c , the second magnetic part 133 has a magnetization direction along the second axial direction, and the second axial direction is opposite to the first axial direction. In other words, the second magnetic part 133 forms two opposite magnetic poles in the second axial direction. Among them, when the first axial direction is the +Z direction, the second axial direction is the -Z direction. When the first axial direction is the -Z direction, the second axial direction is the +Z direction.

[0132] Optionally, please refer to Figures 11 to 13c , both the first magnetic part 131 and the second magnetic part 133 are magnetized regions, and the non-magnetic part 134 is an unmagnetized region. The non-magnetic part 134 is located between the first magnetic part 131 and the second magnetic part 133 in the radial direction.

[0133] A magnetic unit 10 provided in the second embodiment of the present application, the magnetic unit 10 includes an inner magnetic surface 15 and an outer magnetic surface 16 arranged opposite to each other in the radial direction, at least one of the inner magnetic surface 15 and the outer magnetic surface 16 is a plane, the magnetic unit 10 includes a first magnetic part 131, a second magnetic part 133 and a non-magnetic part 134, the first magnetic part 131 has a magnetization direction along a first axial direction; the second magnetic part 133 has a magnetization direction along a second axial direction, and the second axial direction is opposite to the first axial direction; the non-magnetic part 134 is located between the first magnetic part 131 and the second magnetic part 133 in the radial direction. In the present application, by designing that at least one of the inner magnetic surface 15 and the outer magnetic surface 16 of the magnetic unit 10 is a plane, it is convenient for processing and forming, the processing is simple, and the cost is reduced. By designing that the magnetic unit 10 has two magnetization directions, the structure is simple and the cost is low. By designing the non-magnetic part 134, the magnetization amount can be reduced, and the cost can be further reduced.

[0134] In the present application, the width of the non-magnetic part 134 in the radial direction is not limited, and the width of the non-magnetic part 134 in the radial direction can be flexibly designed according to the radial width requirements of the magnetic unit 10.

[0135] In other words, for the radial width requirements of different magnetic units 10, by flexibly designing the width of the non-magnetic part 134 in the radial direction, the radial width requirements of different magnetic units 10 can be met, the process is simple, the cost is low, and the radial width requirements of different magnetic units 10 can be compatible.

[0136] Optionally, the first magnetic part 131, the non-magnetic part 134, and the second magnetic part 133 are of an integral structure, that is, different regions of a magnet.

[0137] The first magnetic part 131 and the second magnetic part 133 are formed by magnetizing the radially inner side of a magnetizable block substrate in the first axial direction and magnetizing the radially outer side in the second axial direction. Physically, it is a substrate. Among them, the unmagnetized part between the radially inner side (inner magnetic surface 15) and the radially outer side (outer magnetic surface 16) is the non-magnetic part 134.

[0138] The first magnetic part 131` and the second magnetic part 133` in the first embodiment are two independent magnetizable block substrates. Physically, they are two substrates. These two independent magnetizable block substrates are magnetized along the first axial direction and the second axial direction respectively. The two independent magnetizable block substrates are assembled together in the radial direction.

[0139] By magnetizing different positions of the same magnet in different directions, magnetic units 10 with multiple different magnetization directions are formed. The inner and outer sides of the magnetic unit 10 have magnetization directions along the axis and in opposite directions, and the middle is a non-magnetic part 134. The setting of the non-magnetic part 134 can reduce the mutual crosstalk between the first magnetic part 131 and the second magnetic part 133, and increase the magnetic pole strength along the axis. Therefore, this embodiment can form a magnetic field distribution along the first axis and the second axis, which can not only enhance the magnetic strength on one side of the axis of the magnetic unit 10, but also improve the magnetic adsorption reliability. In addition, magnetizing and installing one magnet simplifies the assembly process, improves the assembly efficiency, and reduces costs.

[0140] Optionally, at least one of the first magnetic part 131, the non-magnetic part 134, and the second magnetic part 133 is an independent structure. For example, the first magnetic part 131 is an independent magnet, and the non-magnetic part 134 and the second magnetic part 133 are two parts of one magnet. For example, the second magnetic part 133 is an independent magnet, and the non-magnetic part 134 and the first magnetic part 131 are two parts of one magnet. For example, the first magnetic part 131 is an independent magnet, the second magnetic part 133 is another independent magnet, and the non-magnetic part 134 is the unmagnetized part.

[0141] Optionally, the non-magnetic part 134 can be an adhesive layer to bond the first magnetic part 131 and the second magnetic part 133 together.

[0142] Optionally, the non-magnetic part 134 includes a first non-magnetic part 134 and a second non-magnetic part 134 arranged along the axis. The first non-magnetic part 134 is close to the first magnetic surface 11. The second non-magnetic part 134 is close to the second magnetic surface 12. The first non-magnetic part 134 is a magnetic conductor, and the material of the first non-magnetic part 134 includes but is not limited to metals such as iron, cobalt, and nickel or alloys formed by the above metals. The material of the second non-magnetic part 134 includes but is not limited to a magnetic isolation material, such as a steel sheet. Among them, the setting of the non-magnetic part 134 is used to guide the distribution of magnetic induction lines inside the magnetic unit 10. For example, it guides the magnetic induction lines to first extend along the first axis, then extend radially through the first non-magnetic part 134, and then extend along the second axis, so as to enhance the magnetic strength of the second magnetic pole O2 and the fourth magnetic pole O4.

[0143] Of course, in other embodiments, the non-magnetic part 134 can all be metals such as iron, cobalt, and nickel or alloys formed by the above metals.

[0144] Optionally, please refer to Figures 11 to 13c , the magnetic unit 10 has a first magnetic surface 11 and a second magnetic surface 12 arranged opposite to each other along the axis.

The second magnetic surface 12 is respectively the second magnetic pole O2 of the first magnetic part 131 and the fourth magnetic pole O4 of the second magnetic part 133 along the radial direction.

[0147] Optionally, please refer to Figures 11 to 13c , the third magnetic pole O3 has the same magnetism as the second magnetic pole O2, and the third magnetic pole O3 has the opposite magnetism to the first magnetic pole O1. The fourth magnetic pole O4 is the same as the first magnetic pole O1, and the fourth magnetic pole O4 is opposite to the third magnetic pole O3. Thus, when the second magnetic surface 12 is a magnetic attracting surface, the inner side and the outer side on the second magnetic surface 12 of the magnetic unit 10 are two opposite magnetic poles, for example, the second magnetic pole O2 and the fourth magnetic pole O4. Both the second magnetic pole O2 and the fourth magnetic pole O4 can magnetically attract another magnetic unit 10, thereby making the docking surfaces of the two magnetic units 10 tightly magnetically attracted.

[0148] Among them, the first magnetic pole O1 is an N pole or an S pole. In an optional implementation manner, please refer to Figure 11 , the first magnetic pole O1 and the fourth magnetic pole O4 are N poles, and the second magnetic pole O2 and the third magnetic pole O3 are S poles. In another optional implementation manner, the first magnetic pole O1 and the fourth magnetic pole O4 are S poles, and the second magnetic pole O2 and the third magnetic pole O3 are N poles.

[0152] The second magnetic surface 12 is a magnetic attraction surface for attracting the magnetic unit on another device. In other words, when the two magnetic units 10 are magnetically attracted along the axial direction, the first magnetic surface 11 is on the side facing away from the magnetic unit on another device, and the second magnetic surface 12 is the surface facing the magnetic unit on another device, which is the magnetic attraction surface for attracting the magnetic unit on another device.

At the same time, the magnetic induction lines are converged to enhance the magnetic field of the magnetic unit 10.

[0156] For another example, the magnetic isolation sheet 20 is attached to the outer magnetic surface 16, and the inner magnetic surface 15 and the first magnetic surface 11 may not be provided with the magnetic isolation sheet 20. The magnetic isolation sheet 20 is provided on the outer magnetic surface 16 to prevent the magnetic field from leaking from the side where the outer magnetic surface 16 is located, thereby avoiding affecting other structures on the side where the outer magnetic surface 16 of the magnetic unit 10 is located, such as the frame antenna of an electronic device.

In the present application, by designing at least one of the inner magnetic surface 15 and the outer magnetic surface 16 of the magnetic unit 10 to be a plane, it is convenient for processing and forming, the processing is simple, and the cost is reduced.
