DETAILED DESCRIPTION

[0074] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0075] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0076] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0077] See also Figures 1 to 4 , the first embodiment of the present application provides a magnetic unit 10 including a first magnetic portion 131 , a second magnetic portion 132 , and a third magnetic portion 133 .

[0078] The first magnetic portion 131 has a magnetization direction along a first axial direction ( Figures 1 to 4 In other words, the first magnetic portion 131 forms two opposite magnetic poles in the first axial direction, wherein the opposite magnetic poles refer to the N pole and the S pole. The first axial direction may be the +Z direction or the -Z direction.

[0079] The second magnetic portion 132 has a magnetization direction along the radial direction ( Figures 1 to 4 In other words, the second magnetic portion 132 forms two opposite magnetic poles in the radial direction. The radial direction may be the +X direction or the -X direction.

[0080] The third magnetic portion 133 has a magnetization direction along the second axial direction ( Figures 1 to 4 The second axial direction is opposite to the first axial direction. In other words, the third magnetic part 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.

[0081] The radial direction may be a direction from the first magnetic part 131 to the third magnetic part 133, or a direction from the third magnetic part 133 to the first magnetic part 131. The first axial direction, the radial direction, and the second axial direction form a path in the same direction, for example, from one end of the first magnetic part 131 to one end of the third magnetic part 133 via the second magnetic part 132; or from one end of the third magnetic part 133 to one end of the first magnetic part 131 via the second magnetic part 132, so as to guide the magnetic field distribution.

[0082] Optionally, the first magnetic part 131, the second magnetic part 132, and the third magnetic part 133 are an integral structure. By magnetizing different positions of the same permanent magnet in different directions, a magnetic unit 10 with multiple different magnetizing directions is formed. The inner and outer sides of the magnetic unit 10 are magnetizing directions along the axial direction and in opposite directions, respectively, and the middle is a radial magnetizing direction (the inner side points to the outer side or the outer side points to the inner side), so it is possible to form a magnetic field distribution along the first axial direction, radial to the second axial direction, or the second axial direction, radial to the first axial direction, which can not only enhance the magnetic strength on the axial side of the magnetic unit 10, but also improve the magnetic attraction reliability. In addition, while guiding the magnetic field distribution, the magnetic unit 10 can also converge the magnetic induction lines, reduce magnetic leakage, and reduce magnetic interference to other structures.

[0083] Alternatively, the first magnetic portion 131 , the second magnetic portion 132 , and the third magnetic portion 133 are three independent structures that are fixed together into an integrated structure.

[0084] A magnetic unit 10 provided in an embodiment of the present application includes a first magnetic part 131, a second magnetic part 132 and a third magnetic part 133, wherein the first magnetic part 131 has a magnetizing direction along a first axial direction; the second magnetic part 132 has a magnetizing direction along a radial direction; the third magnetic part 133 has a magnetizing direction along a second axial direction, and the second axial direction is opposite to the first axial direction. In this way, the magnetic unit 10 has a structure with three magnetizing directions, which guides the magnetic field distribution, enhances the magnetic strength, and improves the magnetic attraction reliability.

[0085] Optional, see Figures 1 to 4 The magnetic unit 10 has a first magnetic surface 11 and a second magnetic surface 12 which are arranged opposite to each other in the axial direction.

[0086] See also Figure 5 , the first magnetic surface 11 has four magnetic poles along the radial direction. Optionally, the first magnetic surface 11 along the radial direction respectively includes a first magnetic pole O1 of the first magnetic part 131, a third magnetic pole O3 of the second magnetic part 132, a fourth magnetic pole O4 of the second magnetic part 132, and a fifth magnetic pole O5 of the third magnetic part 133.

[0087] See also Figure 6 The second magnetic surface 12 has four magnetic poles along the radial direction. The second magnetic surface 12 has four magnetic poles along the radial direction, namely, the second magnetic pole O2 of the first magnetic part 131, the third magnetic pole O3 of the second magnetic part 132, the fourth magnetic pole O4 of the second magnetic part 132, and the sixth magnetic pole O6 of the third magnetic part 133.

[0088] In an alternative implementation, see Figure 2 and Figure 3The third magnetic pole O3 has the same magnetism as the first magnetic pole O1, and the third magnetic pole O3 has an opposite magnetism to the second magnetic pole O2, the fourth magnetic pole O4 has the same magnetism as the fifth magnetic pole O5, and the fourth magnetic pole O4 is opposite to the sixth magnetic pole O6. Thus, the third magnetic pole O3 provided in this embodiment can strengthen the magnetic strength of the first magnetic pole O1, and the fourth magnetic pole O4 can strengthen the magnetic strength of the fifth magnetic pole O5. The inner and outer sides of the first magnetic surface 11 of the magnetic unit 10 are two opposite magnetic poles, and the magnetic pole strengths of the inner and outer sides are stronger under radial magnetization.

[0089] Wherein, the first magnetic pole O1 is an N pole or an S pole. In an optional implementation manner, please refer to Figure 2 , the first magnetic pole O1, the third magnetic pole O3, and the fifth magnetic pole O5 are N poles, and the second magnetic pole O2, the fourth magnetic pole O4, and the sixth magnetic pole O6 are S poles, forming a first magnetic field distribution and a first converged magnetic induction line. In another optional embodiment, please refer to Figure 3 The first magnetic pole O1, the third magnetic pole O3, and the fifth magnetic pole O5 are S poles, and the second magnetic pole O2, the fourth magnetic pole O4, and the sixth magnetic pole O6 are N poles, forming a second magnetic field distribution and a second convergent magnetic induction line.

[0090] Optional, see Figure 1 and Figure 4 The third magnetic pole O3 has the same magnetism as the second magnetic pole O2, and the third magnetic pole O3 is opposite to the first magnetic pole O1, the fourth magnetic pole O4 is the same as the sixth magnetic pole O6, and the fourth magnetic pole O4 is opposite to the fifth magnetic pole O5. In this way, the third magnetic pole O3 provided in this embodiment can strengthen the magnetic strength of the first magnetic pole O1, and the fourth magnetic pole O4 can strengthen the magnetic strength of the fifth magnetic pole O5. The inner and outer sides of the first magnetic surface 11 of the magnetic unit 10 are two opposite magnetic poles, and the magnetic pole strengths of the inner and outer sides are stronger under the radial magnetization effect.

[0091] Wherein, the first magnetic pole O1 is an N pole or an S pole. In an optional implementation manner, please refer to Figure 1 , the first magnetic pole O1, the fourth magnetic pole O4, and the sixth magnetic pole O6 are N poles, and the first magnetic pole O1, the third magnetic pole O3, and the fifth magnetic pole O5 are S poles, forming a third magnetic field distribution and a third converged magnetic induction line. In another optional embodiment, please refer to Figure 4 The first magnetic pole O1, the fourth magnetic pole O4, and the sixth magnetic pole O6 are S poles, and the second magnetic pole O2, the third magnetic pole O3, and the fifth magnetic pole O5 are N poles, forming a fourth magnetic field distribution and a fourth convergent magnetic induction line.

[0092] In this embodiment, the magnetic unit 10 has four magnetic poles in the radial direction, the two inner and outer magnetic poles are two axial magnetic poles to guide the magnetic induction lines to be distributed axially in the first magnetic part 131 and the third magnetic part 133, and the two middle magnetic poles are radial magnetic poles, which can strengthen the strength of the inner and outer magnetic poles to guide the magnetic induction lines to be distributed radially in the second magnetic part 132. Figure 1 The +X direction (the direction indicated by the arrow is the + direction) is the direction from the outside to the inside.

[0093] The present application does not make any specific limitation on the shape of the magnetic unit 10. Optionally, the magnetic unit 10 includes but is not limited to any one of an arc-shaped bar, a rectangular bar, a trapezoidal bar, a bow-shaped bar, a bent bar, and a curved bar. The present application does not make any specific limitation on the length and width of the magnetic unit 10. When the magnetic unit 10 is a rectangular bar, the shape of the magnetic unit 10 includes but is not limited to a cube or a cuboid. When the magnetic unit 10 is an arc-shaped bar, the curvature of the magnetic unit 10 is not specifically limited. When the magnetic unit 10 is a bent bar, the extension trajectory of the magnetic unit 10 can be V-shaped, L-shaped, etc. When the magnetic unit 10 is a curved bar, the extension trajectory of the magnetic unit 10 can be C-shaped, U-shaped, S-shaped, etc.

[0094] See also Figure 7a-7f The embodiment of the present application further provides a magnetic assembly 13, comprising a plurality of magnetic units 10 described in any one of the above. The shapes of the magnetic units 10 included in one magnetic assembly 13 can be the same shape or different shapes.

[0095] Optionally, the plurality of magnetic units 10 are arranged in at least one of a polygonal arrangement and a circular arrangement; or, the plurality of magnetic units 10 are arranged in a ring shape, and an arc-shaped opening of at least one of the magnetic units 10 faces outward.

[0096] Optionally, multiple magnetic units 10 are arranged in a certain manner to form a magnetic assembly 13. The present application does not specifically limit the number of magnetic units 10 that constitute the magnetic assembly 13. For example, the magnetic assembly 13 includes 2, or 3, or 4, or 5, or 6, or 7, or 8 magnetic units 10. For example, 2 rectangular strips of magnetic units 10 are arranged in the same direction or in different directions to form a magnetic assembly 13 with a certain pattern. For another example, 3 rectangular strips of magnetic units 10 are arranged in the same direction or in different directions to form a magnetic assembly 13 with a certain pattern. For another example, please refer to Figure 7a , the four rectangular magnetic units 10 are arranged in different directions to form a rectangular pattern magnetic assembly 13. For another example, please refer to Figure 7b , 8 rectangular magnetic units 10 are arranged in different directions to form an octagonal magnetic assembly 13. For another example, please refer to Figure 7c, the directions of the six arc-shaped magnetic units 10 are all outward, so as to form a magnetic component 13 with six reverse arc-shaped edges. For another example, please refer to Figure 7d , a plurality of arc-shaped magnetic units 10 surround to form a ring. For another example, refer to Figure 7e , a plurality of rectangular magnetic units 10 surround to form an approximately circular ring. For another example, refer to Figure 7f , a plurality of trapezoidal strip magnetic units 10 surround to form an approximately circular ring shape.

[0097] Optionally, the magnetic assembly 13 can form an annular pattern or a non-annular pattern. When the magnetic assembly 13 forms an annular pattern, the center side of the ring of the magnetic unit 10 is the inner side of the magnetic unit 10, and the outer side of the ring of the magnetic unit 10 is the outer side of the magnetic unit 10. 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 side of the magnetic assembly 13 is all S poles, and the outer side of the magnetic assembly 13 is all N poles. The radial direction from the inside to the outside of the magnetic assembly 13 is S pole and N pole respectively, so that the inner side of the magnetic assembly 13 has a stronger S pole magnetism, and the outer side of the magnetic assembly 13 has a stronger N pole magnetism.

[0098] Optional, see Figure 8 , a magnetic unit 10 is provided in the second embodiment of the present application. The magnetic unit 10 is in the form of a rectangular bar or a trapezoidal bar. The rectangular bar includes but is not limited to a cube and a cuboid.

[0099] See also Figure 8 The magnetic unit 10 includes a first magnetic portion 131 , a second magnetic portion 132 , and a connecting portion 134 .

[0100] See also Figure 8 , 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, wherein the opposite magnetic poles refer to the N pole and the S pole.

[0101] See also Figure 8 The second magnetic portion 132 has a magnetizing direction along a second axial direction, and the second axial direction is opposite to the first axial direction. In other words, the second magnetic portion 132 forms two opposite magnetic poles in the second axial direction.

[0102] The connecting portion 134 is radially disposed between the first magnetic portion 131 and the second magnetic portion 132. The connecting portion 134 can allow the first magnetic portion 131 and the second magnetic portion 132 to have a certain distance, so that the magnetic induction lines in the first magnetic portion 131 are separated from the magnetic induction lines in the second magnetic portion 132, thereby reducing the crosstalk between the first magnetic portion 131 and the second magnetic portion 132, making the magnetic induction lines in the first magnetic portion 131 more converged, and the magnetic induction lines in the second magnetic portion 132 more converged, thereby reducing magnetic leakage.

[0103] Optionally, the first magnetic part 131, the connecting part 134, and the second magnetic part 132 are an integral structure.

[0140] See also Fig. 20 The electronic device 100 provided in the embodiment of the present application includes a first housing 110, a first charging coil 120 and a first magnetic assembly 130. The first housing 110 includes but is not limited to a back cover 40. This embodiment is described by taking the first housing 110 as the back cover 40 as an example.

[0141] See also Fig. 20 , the first charging coil 120 is disposed in the first housing 110 for wirelessly transmitting electric energy. The first charging coil 120 may be a charging receiving coil or a charging transmitting coil. The following embodiments take the first charging coil 120 as an example of a charging receiving coil. For example, the first charging coil 120 is used to receive electric energy through coil coupling, thereby realizing charging of the electronic device 100.

[0142] Specifically, the first charging coil 120 is arranged close to the inner side of the first housing 110. The electronic device 100 is further provided with a charging receiving module (not shown), which is electrically connected to the first charging coil 120 and the battery 70, and is used to transmit the energy received by the first charging coil 120 to the battery 70 to charge the battery 70.

The first magnetic component 130 is used to achieve position alignment with the second magnetic component 230 in the charging seat 400 through mutual force. When the position of the first magnetic component 130 is aligned with the position of the second magnetic component 230, the position of the first charging coil 120 in the electronic device 100 is aligned with the position of the second charging coil 220 (for example, the charging transmitter coil) in the charging seat 400, that is, the center position of the first charging coil 120 corresponds to or nearly corresponds to the center position of the second charging coil 220. Further, the coil size of the first charging coil 120 is similar to the coil size of the second charging coil 220 (for example, the same). In this way, the effective coupling area between the first charging coil 120 and the second charging coil 220 is maximized, thereby improving the charging efficiency between the first charging coil 120 in the electronic device 100 and the second charging coil 220 in the charging seat 400.

[0145] See also Fig.21 The first magnetic unit 130a includes a first magnetic portion 131 and a second magnetic portion 132 connected to each other. The first magnetic portion 131 and the second magnetic portion 132 are connected along a second direction X. The second direction X is a lateral direction.

In other words, the first magnetic part 131 is a magnet, and further, the first magnetic part 131 can be a permanent magnet magnetized along the first direction Z.

[0147] Magnetization refers to applying a magnetic field to a permanent magnet along the magnetic field orientation direction, gradually increasing the magnetic field strength to reach a technical saturation state. For example, magnetization is performed along a first direction Z, so that the first magnetic unit 130a has different magnetic poles along the first direction Z. For example, the first magnetic unit 130a is a magnet, and the two ends of the first magnetic unit 130a along the first direction Z are respectively an S pole and an N pole.

[0148] The second magnetic part 132 has a magnetization direction along the second direction X. The second direction X is located in the plane of the width and length of the electronic device 100. In other words, the second magnetic part 132 is a magnet, and further, the second magnetic part 132 can be a permanent magnet magnetized along the second direction X.

[0149] The first direction Z is the direction in which the first charging coil 120 and the second charging coil 220 are opposite to each other.

This embodiment takes the first direction Z and the second direction X intersecting perpendicularly as an example.

[0151] The first magnetic part 131 and the second magnetic part 132 are used to increase the magnetic attraction of the first magnetic component 130. Since one side of the first magnetic part 131 along the thickness direction is the charging side, and the second magnetic part 132 is magnetized in the lateral direction, the end of the second magnetic part 132 close to the first magnetic part 131 is charged with the same magnetism as the charging side of the first magnetic part 131. At this time, the magnetism of the end of the second magnetic part 132 close to the first magnetic part 131 is the same as the magnetism of the charging side of the first magnetic part 131, which is equivalent to enhancing the magnetic field strength of the charging side of the first magnetic part 131, thereby improving the attraction of the charging side of the first magnetic unit 130a.

The first direction Z is the direction in which the first charging coil 120 is relative to the second charging coil 220, and the second magnetic portion 132 is opposite to the first charging coil 120. Direction X intersects with the first direction Z, the magnetism of one end of the second magnetic portion 132 close to the first magnetic portion 131 is the same as the magnetism of the charging side of the first magnetic portion 131, the first magnetic portion 131 and the second magnetic portion 132 are used to increase the magnetic attraction of the first magnetic component 130, and the setting of the second magnetic portion 132 is equivalent to enhancing the magnetic field strength on the charging side of the first magnetic portion 131, thereby increasing the suction force on the charging side of the first magnetic unit 130a, thereby improving the charging alignment rate of the first charging coil 120 in the electronic device 100 and the second charging coil 220 in the charging seat 400, and improving the charging efficiency between the electronic device 100 and the charging seat 400.

[0153] Optional, see Fig.21, the first magnetic part 131 forms a first S pole 1311 and a first N pole 1312 in the first direction Z (longitudinal direction).

The polarity of the end of the second magnetic part 132 close to the first magnetic part 131 is the same as the polarity of the charging side of the first magnetic part 131. The end of the second magnetic part 132 close to the first magnetic part 131 is used to enhance the polarity of the charging side of the first magnetic part 131 and enhance the magnetic field on the charging side of the first magnetic unit 130a.

[0154] In this implementation, please refer to Fig.21 The discharge side of the charging stand 400 has the magnetic pole corresponding to the first magnetic part 131 as the N pole, so as to achieve attraction between the discharge side of the charging stand 400 and the charging side of the electronic device 100. Under the action of the suction force, the first charging coil 120 of the electronic device 100 and the second charging coil 220 of the charging stand 400 are aligned.

[0155] For optional reference, see Fig. 22 , the first N-pole 1312 is located on the side facing the first charging coil 120.

The second S-pole 1321 is located on the side away from the first magnetic part 131.

[0156] In this embodiment, the magnetic pole corresponding to the first magnetic part 131 on the discharge side of the charging stand 400 is the S pole, so as to achieve attraction between the discharge side of the charging stand 400 and the charging side of the electronic device 100. Under the action of the suction force, the first charging coil 120 of the electronic device 100 and the second charging coil 220 of the charging stand 400 are directly opposite.

[0157] See also Fig.23 The first magnetic unit 130a further includes a third magnetic portion 133. The first magnetic portion 131, the second magnetic portion 132 and the third magnetic portion 133 are arranged along the second direction X in sequence.

[0158] The third magnetic part 133 has a magnetization direction along the first direction Z. In other words, the third magnetic part 133 is a magnet, and further, the third magnetic part 133 can be a permanent magnet after being magnetized along the first direction Z. The end of the second magnetic part 132 close to the third magnetic part 133 has the same magnetism as the charging side of the third magnetic part 133. In this way, the end of the second magnetic part 132 close to the third magnetic part 133 has the same magnetism as the charging side of the third magnetic part 133, and then, the second magnetic part 132 can enhance the magnetic field strength on the charging side of the third magnetic part 133, thereby further improving the suction force on the charging side of the first magnetic unit 130a.

[0159] Optional, see Fig.23 , the second S pole 1321 is located on a side close to the first magnetic part 131. The second N pole 1322 is located on a side away from the first magnetic part 131 (a side close to the third magnetic part 133). The third magnetic part 133 forms a third S pole 1331 and a third N pole 1332 in the first direction Z. The third S pole 1331 corresponds to the first N pole 1312 along the second direction X. The third N pole 1332 corresponds to the first S pole 1311 along the second direction X. In this way, the end of the second magnetic part 132 close to the third magnetic part 133 has the same magnetism as the charging side of the third magnetic part 133, and thus, the second magnetic part 132 can enhance the magnetic field strength on the charging side of the third magnetic part 133, thereby further improving the suction force on the charging side of the first magnetic unit 130a.

[0160] Optional, see Fig.24 , the second N pole 1322 is located on a side close to the first magnetic part 131. The second S pole 1321 is located on a side away from the first magnetic part 131 (a side close to the third magnetic part 133). The third magnetic part 133 forms a third S pole 1331 and a third N pole 1332 in the first direction Z. The third S pole 1331 corresponds to the first N pole 1312 along the second direction X. The third N pole 1332 corresponds to the first S pole 1311 along the second direction X. In this way, the end of the second magnetic part 132 close to the third magnetic part 133 has the same magnetism as the charging side of the third magnetic part 133, and thus, the second magnetic part 132 can enhance the magnetic field strength on the charging side of the third magnetic part 133, thereby further improving the suction force on the charging side of the first magnetic unit 130a.

[0161] Optional, see Figures 25a to 25i The number of the first magnetic unit 130a can be one, and the shape of the first magnetic unit 130a is not limited. Optionally, the first magnetic unit 130a is in a rectangular strip shape, an arc shape, a C shape, a V shape, a U shape, etc.

[0162] Correspondingly, a magnet having a shape similar to or the same as that of the first magnetic unit 130a and an arrangement similar to or the same as that of the first magnetic unit 130a may be disposed on the charging stand 400.

[0163] In an alternative embodiment, see Fig.25a The first magnetic unit 130 a is in a rectangular strip shape and is disposed along the length direction of the electronic device 100 .

[0164] In this embodiment, a rectangular first magnetic unit 130a is arranged along the length direction of the electronic device 100, and a second magnetic unit 230a (see Fig.24 ), so that the first magnetic unit 130a and the second magnetic unit 230a can be aligned at least in the width direction of the electronic device 100, and roughly aligned in the length direction.

[0165] In an optional implementation, the first magnetic unit 130 a is in the shape of a rectangular strip, and the first magnetic unit 130 a is arranged along the width direction of the electronic device 100 .

[0166] In this embodiment, a rectangular strip-shaped first magnetic unit 130a is arranged along the width direction of the electronic device 100, and a second magnetic unit 230a adapted to the first magnetic unit 130a is provided on the charging stand 400. In this way, the first magnetic unit 130a and the second magnetic unit 230a can be aligned at least in the length direction of the electronic device 100, and roughly aligned in the width direction.

[0167] In an alternative embodiment, see Figure 25h The first magnetic unit 130 a is in a rectangular strip shape, and an extension direction of the first magnetic unit 130 a intersects with a width direction (second direction X) of the electronic device 100 , and an extension direction of the first magnetic unit 130 a intersects with a length direction of the electronic device 100 .

[0168] In this embodiment, a rectangular strip-shaped first magnetic unit 130a is arranged to be inclined relative to the length and width directions of the electronic device 100, and a second magnetic unit 230a adapted to the first magnetic unit 130a is provided on the charging stand 400. In this way, the first magnetic unit 130a and the second magnetic unit 230a can be aligned in the length and width directions of the electronic device 100.

[0169] In an optional implementation, the first magnetic unit 130a has different extension directions in the length and width planes of the electronic device 100. For example, see Figure 25e-Figure 25g, the extension direction of the first magnetic unit 130a is in an arc shape, a C shape, a V shape, a U shape, etc. In this embodiment, the first magnetic unit 130a has different extension directions in the length and width planes of the electronic device 100, so that it can be limited in different dimensions in the length and width planes of the electronic device 100, thereby achieving alignment in both the length and width directions of the electronic device 100.

[0170] Furthermore, the first charging coil 120 is substantially circular. The first magnetic unit 130a may be adjacent to the first charging coil 120 and change with the outer contour of the first charging coil 120, thereby improving the arrangement density of components between the first magnetic unit 130a and the first charging coil 120 and reducing the area occupied by the first magnetic component 130 and the first charging coil 120.

[0171] Optional, see Figures 26a to 26c The first magnetic assembly 130 includes a plurality of first magnetic units 130 a. The plurality of first magnetic units 130 a are arranged around the first charging coil 120 in an interval or in a connected manner.

[0172] In this embodiment, there are multiple first magnetic units 130 a . The multiple first magnetic units 130 a can be arranged around the first charging coil 120 at intervals; or the multiple first magnetic units 130 a can be connected into a ring body and arranged around the first charging coil 120 .

[0173] By arranging a plurality of first magnetic units 130a around the first charging coil 120, accurate alignment can be achieved at different positions of the first charging coil 120, thereby facilitating alignment of the first charging coil 120 with the second charging coil 220 in the charging seat 400. In addition, the plurality of first magnetic units 130a are arranged close to the outer contour of the first charging coil 120, thereby improving the compactness of device arrangement between the first magnetic units 130a and the first charging coil 120 and reducing the area occupied by the first magnetic assembly 130 and the first charging coil 120.

[0174] In other embodiments, the structures of the plurality of first magnetic units 130a are different, for example, one of the first magnetic units 130a is in the shape of an elongated strip, and another of the first magnetic units 130a is in the shape of an arc. The elongated first magnetic unit 130a is arranged along the length direction of the electronic device 100, and the charging stand 400 has a second magnetic unit 230a adapted to the first magnetic unit 130a, so that the first magnetic unit 130a and the second magnetic unit 230a can be aligned in the width direction (second direction X) of the electronic device 100. The arc-shaped first magnetic unit 130a is arranged at intervals from the elongated first magnetic unit 130a, that is, it is arranged on different sides of the first charging coil 120, thereby achieving accurate alignment at different positions of the first charging coil 120.

[0175] Optionally, at least one of the first magnetic units 130a is in a strip shape.

[0176] For example, see Fig.25c , Fig.25d , Figure 26b , at least one of the first magnetic units 130a is disposed along the second direction X. For example, one first magnetic unit 130a is disposed along the second direction X. For another example, two first magnetic units 130a are both disposed along the second direction X, and the two first magnetic units 130a are respectively disposed on opposite sides of the first charging coil 120 .

[0177] For example, see Fig.25a , Fig.25b , Fig.25c , at least one of the first magnetic units 130a is arranged along a third direction Y. The third direction Y is perpendicular to the second direction X. The third direction Y is perpendicular to the first direction Z. When the second direction X is the width direction (second direction X) of the electronic device 100, the third direction Y may be the length direction of the electronic device 100.

[0178] For example, one first magnetic unit 130 a is disposed along the third direction Y. For another example, two first magnetic units 130 a are both disposed along the third direction Y, and the two first magnetic units 130 a are respectively disposed on opposite sides of the first charging coil 120 .

[0179] For example, see Figure 26b , at least one of the first magnetic units 130a is arranged along the second direction X, and at least one of the first magnetic units 130a is arranged along the third direction Y. For example, one first magnetic unit 130a is arranged along the second direction X, and one first magnetic unit 130a is arranged along the third direction Y, so as to perform position alignment in the width direction and the length direction within the charging surface.

[0180] Optional, see Figure 26b and Fig.26c , the first magnetic units 130a are provided on both sides of the first charging coil 120 along the second direction X. The first magnetic units 130a are provided on both sides of the first charging coil 120 along the third direction Y. For example, two first magnetic units 130a are respectively provided on opposite sides of the first charging coil 120 along the second direction X, and two first magnetic units 130a are respectively provided on opposite sides of the first charging coil 120 along the third direction Y, so as to align the positions in the width direction and the length direction within the charging surface.

[0181] Optional, see Figure 25h and Fig.25i , Fig.26cAt least one of the first magnetic units 130a is in a strip shape. The plurality of first magnetic units 130a have at least two different extension directions. The extension direction of at least one of the first magnetic units 130a obliquely intersects with the second direction X and obliquely intersects with the third direction Y.

[0182] For example, one first magnetic unit 130a is inclined 45° toward the left side in the third direction Y. Another first magnetic unit 130a is inclined 45° toward the right side in the third direction Y. Each first magnetic unit 130a can accurately limit the width and length directions of the charging surface.

[0183] Optionally, the two first magnetic units 130a are respectively arranged on opposite sides of the first charging coil 120 along the second direction X, and the two first magnetic units 130a are respectively arranged on opposite sides of the first charging coil 120 along the third direction Y, the two first magnetic units 130a are respectively arranged on opposite sides of the first charging coil 120 along the third direction Y and tilted 45° toward the left, and the two first magnetic units 130a are respectively arranged on opposite sides of the first charging coil 120 along the third direction Y and tilted 45° toward the right. By providing more first magnetic units 130a and arranging them around the circumference of the first charging coil 120, it is equivalent to arranging multiple positioning points around the circumference of the first charging coil 120. By accurately aligning the multiple first magnetic units 130a around the first charging coil 120 with the multiple second magnetic units 230a on the charging seat 400, the multiple positioning points around the first charging coil 120 are positioned, and then the first charging coil 120 and the second charging coil 220 are accurately aligned.

[0184] Optional, see Figures 27a to 27c At least one of the first magnetic units 130 a is in an arc shape, and an arc-shaped opening of the first magnetic unit 130 a is oriented toward a side away from the first charging coil 120 .

[0185] In other words, the first magnetic unit 130a extends in a reverse arc shape. At this time, the extension track of the first magnetic unit 130a is relatively complex. When the extension track of the first magnetic unit 130a is complex, the uniqueness of the first magnetic component 130 and the second magnetic component 230 when they are aligned is stronger, and there are restrictions on multiple directions of the charging surface, thereby further improving the first magnetic component 130 and the second magnetic component 230 (see Fig. 20 )Alignment accuracy.

[0186] For further information, see Figures 27a to 27c The plurality of first magnetic units 130a are all in an arc shape, and the plurality of first magnetic units 130a are sequentially connected to form a closed ring or sequentially spaced.

[0187] In this embodiment, the first magnetic component 130 formed by the arc-shaped openings of the plurality of arc-shaped first magnetic units 130a facing the side away from the first charging coil 120 extends in multiple directions within the charging plane, and the extension trajectory of the first magnetic component 130 is relatively complex. The extension trajectory of the first magnetic component 130 surrounds the first charging coil 120, which is more conducive to precise positioning on the first charging coil 120 than not surrounding the first charging coil 120. The first magnetic component 130 has more extension directions and a more complex extension trajectory, and is more unique when aligning the first magnetic component 130 with the second magnetic component 230, and is limited in multiple directions of the charging surface, thereby further improving the alignment accuracy of the first magnetic component 130 and the second magnetic component 230.

[0188] See also Fig.28 , a charging stand 400 provided in the first embodiment of the present application includes a second shell 410 , a second charging coil 220 and a second magnetic component 230 .

[0189] Optionally, the second charging coil 220 is disposed in the second shell 410 , and the second charging coil 220 is used for wirelessly transmitting electrical energy.

[0190] The second magnetic component 230 is disposed in the second housing 410 and is disposed adjacent to the second charging coil 220. The second magnetic component 230 is positioned to face the first magnetic component 130 in the electronic device 100. At this time, the second charging coil 220 faces the first charging coil 120, and the signal transmission efficiency between the second charging coil 220 and the first charging coil 120 is the highest.

[0191] Optional, see Fig.28 The second magnetic assembly 230 includes at least one second magnetic unit 230a. The number of the second magnetic unit 230a can be one or more. The present application hereinafter exemplifies the structure of a single second magnetic unit 230a.

[0192] See also Fig.21 and Fig. 22 The second magnetic unit 230a includes a fourth magnetic portion 231 and a fifth magnetic portion 232 connected to each other. The fourth magnetic portion 231 and the fifth magnetic portion 232 are connected along a second direction X. The second direction X is a lateral direction.

[0193] The fourth magnetic part 231 has a magnetization direction along the first direction Z. The first direction Z is a longitudinal direction, which is also a thickness direction of the second magnetic unit 230a and a thickness direction of the electronic device 100. In other words, the fourth magnetic part 231 is a magnet, and further, the fourth magnetic part 231 can be a permanent magnet magnetized along the first direction Z.

[0194] The fifth magnetic part 232 has a magnetization direction along the second direction X. The second direction X is located in the plane of the width and length of the electronic device 100. In other words, the second magnetic part 132 is a magnet, and further, the second magnetic part 132 can be a permanent magnet magnetized along the second direction X.

[0195] The first direction Z is the direction in which the second charging coil 220 is opposite to the first charging coil 120. The second charging coil 220 and the first charging coil 120 are arranged opposite to each other along the thickness direction of the electronic device 100. As mentioned above, the first direction Z is the thickness direction of the electronic device 100. The second direction X intersects with the first direction Z.

[0196] The fourth magnet portion 231 and the fifth magnet portion 232 are used to increase the magnetic attraction of the second magnetic assembly 230. Since one side of the fourth magnet portion 231 along the thickness direction is the discharge side, the fifth magnet portion 232 is magnetized in the lateral direction, and one end of the fifth magnet portion 232 close to the fourth magnet portion 231 is charged with the same magnetism as the discharge side of the fourth magnet portion 231. At this time, the magnetism of one end of the fifth magnet portion 232 close to the fourth magnet portion 231 is the same as the magnetism of the discharge side of the fourth magnet portion 231, which is equivalent to enhancing the magnetic field strength of the discharge side of the fourth magnet portion 231, thereby increasing the attraction of the discharge side of the second magnetic unit 230a.

Direction X intersects with the first direction Z, the magnetism of one end of the fifth magnet portion 232 close to the fourth magnet portion 231 is the same as the magnetism of the charging side of the fourth magnet portion 231, the fourth magnet portion 231 and the fifth magnet portion 232 are used to increase the magnetic attraction of the second magnetic component 230, and the setting of the fifth magnet portion 232 is equivalent to enhancing the magnetic field strength of the discharge side of the fourth magnet portion 231, thereby increasing the suction force of the discharge side of the second magnetic unit 230a, thereby improving the charging alignment rate of the first charging coil 120 in the electronic device 100 and the second charging coil 220 in the charging seat 400, and improving the charging efficiency between the electronic device 100 and the charging seat 400.

[0198] Optional, see Fig.21The fourth magnetic part 231 forms a fourth S pole 2311 and a fourth N pole 2312 in the first direction Z (longitudinal direction). The fourth N pole 2312 is located on the side facing the first charging coil 120. The fourth N pole 2312 is located on the side facing the first charging coil 120. That is, the fourth N pole 2312 is located on the charging side of the fourth magnetic part 231.

[0199] See also Fig.21 , the fifth magnet portion 232 forms a fifth S pole 2321 and a fifth N pole 2322 in the second direction X. The fifth N pole 2322 is located on a side close to the fourth magnet portion 231. The fifth S pole 2321 is located on a side away from the fourth magnet portion 231. The polarity of the end of the fifth magnet portion 232 close to the fourth magnet portion 231 is the same as the polarity of the discharge side of the fourth magnet portion 231. The end of the fifth magnet portion 232 close to the fourth magnet portion 231 is used to enhance the polarity of the discharge side of the fourth magnet portion 231 and enhance the magnetic field on the discharge side of the second magnetic unit 230a.

[0200] In this embodiment, the magnetic pole corresponding to the fourth magnet part 231 on the charging side of the electronic device 100 is the S pole, so as to achieve attraction between the discharge side of the charging stand 400 and the charging side of the electronic device 100. Under the action of the suction force, the first charging coil 120 of the electronic device 100 and the second charging coil 220 of the charging stand 400 are directly opposite.

[0201] For optional reference, see Fig. 22 , the fourth S-pole 2311 is located on the side facing the first charging coil 120. That is, the fourth S-pole 2311 is located on the discharge side of the fourth magnet portion 231. The fifth S-pole 2321 is located on the side close to the fourth magnet portion 231. The fifth N-pole 2322 is located on the side away from the fourth magnet portion 231.

[0202] In this embodiment, the magnetic pole corresponding to the fourth magnetic part 231 on the charging side of the electronic device 100 is the N pole, so as to achieve attraction between the discharge side of the charging stand 400 and the charging side of the electronic device 100. Under the action of the suction force, the first charging coil 120 of the electronic device 100 and the second charging coil 220 of the charging stand 400 are directly opposite.

[0203] See also Fig.23 and Fig.24 The second magnetic unit 230a further includes a sixth magnetic portion 233. The fourth magnetic portion 231, the fifth magnetic portion 232 and the sixth magnetic portion 233 are arranged along the second direction X in sequence.

[0204] The sixth magnet portion 233 has a magnetization direction along the first direction Z. In other words, the sixth magnet portion 233 is a magnet, and further, the sixth magnet portion 233 can be a permanent magnet after being magnetized along the first direction Z. The end of the fifth magnet portion 232 close to the sixth magnet portion 233 has the same magnetism as the discharge side of the sixth magnet portion 233. In this way, the end of the fifth magnet portion 232 close to the sixth magnet portion 233 has the same magnetism as the discharge side of the sixth magnet portion 233, and further, the fifth magnet portion 232 can enhance the magnetic field strength on the discharge side of the sixth magnet portion 233, thereby further improving the suction force on the discharge side of the second magnetic unit 230a.

[0205] See also Fig.23 and Fig.24 , the sixth magnet part 233 forms a sixth S pole 2331 and a sixth N pole 2332 in the first direction Z. The sixth S pole 2331 corresponds to the sixth N pole 2332 along the second direction X. The sixth N pole 2332 corresponds to the sixth S pole 2331 along the second direction X. In this way, the end of the fifth magnet part 232 close to the sixth magnet part 233 has the same magnetism as the discharge side of the sixth magnet part 233, and thus, the fifth magnet part 232 can enhance the magnetic field strength on the discharge side of the sixth magnet part 233, thereby further improving the suction force on the discharge side of the second magnetic unit 230a.

[0206] See also Fig.29 and Fig.30 , an electronic device accessory 300 is provided in an embodiment of the present application. The electronic device accessory 300 includes but is not limited to a protective shell, a rear cover decoration, a rear cover support, and the like. Fig.29 Take the electronic device accessory 300 as a protective case as an example.

[0207] See also Fig.29 and Fig.30 The electronic device accessory 300 includes a third magnetic component 331. The electronic device accessory 300 is disposed between the back cover 40 of the electronic device 100 and the charging base 400. By arranging the third magnetic component 331 in the electronic device accessory 300, the third magnetic component 331 can be aligned with the fourth magnetic component 431 in the charging base 400, so as to achieve accurate alignment between the first charging coil 120 in the electronic device 100 and the second charging coil 220 in the charging base 400.

[0208] The first part of the third magnetic component 331 has a magnetization direction along the first direction Z, i.e., longitudinal magnetization. The second part of the third magnetic component 331 has a magnetization direction along the second direction X, i.e., transverse magnetization. The first direction Z is the direction in which the electronic device accessory 300 is opposite to the charging stand 400. The second direction X intersects with the first direction Z. The magnetism of the second part of the third magnetic component 331, which is close to one end of the first part of the third magnetic component 331, is the same as the magnetism of the charging side of the first part of the third magnetic component 331. The first part of the third magnetic component 331 is used to attract the first part (e.g., the fourth magnet part 231) on the charging stand 400. The second part of the third magnetic component 331 is used to attract the second part (e.g., the fifth magnet part 232) on the charging stand 400.

The second part of the third magnetic assembly 331 may be the eighth magnet portion 3312, which is a magnet with transverse magnetic charge.

[0210] The seventh magnet portion 3311 and the eighth magnet portion 3312 are used to increase the magnetic attraction of the third magnetic assembly 331. Since one side of the seventh magnet portion 3311 along the thickness direction is the charging side of the electronic device 100 (hereinafter referred to as the charging side), the eighth magnet portion 3312 is magnetized in the lateral direction, and the end of the eighth magnet portion 3312 close to the seventh magnet portion 3311 is charged with the same magnetism as the charging side of the seventh magnet portion 3311. At this time, the magnetism of the end of the eighth magnet portion 3312 close to the seventh magnet portion 3311 is the same as the magnetism of the charging side of the seventh magnet portion 3311, which is equivalent to enhancing the magnetic field strength of the charging side of the seventh magnet portion 3311, thereby increasing the attraction of the charging side of the third magnetic assembly 331.

[0211] The electronic device accessory 300 provided in the embodiment of the present application is designed such that the first part of the third magnetic component 331 has a magnetization direction along the first direction Z, and the second part of the third magnetic component 331 has a magnetization direction along the second direction X. The first direction Z is the direction in which the electronic device accessory 300 is relative to the electronic device 100, and the second direction X intersects with the first direction Z. The magnetism of the second part of the third magnetic component 331, which is close to one end of the first part of the third magnetic component 331, is the same as the magnetism of the charging side of the first part of the third magnetic component 331. The first part of the third magnetic component 331 is used to attract the first part on the charging base 400, and the second part of the third magnetic component 331 is used to attract the second part on the charging base 400. The above design is used to increase the magnetic attraction between the third magnetic component 331 and the charging base 400 in the electronic device accessory 300, thereby improving the charging alignment rate between the first charging coil 120 in the electronic device 100 and the second charging coil 220 in the charging base 400, and improving the charging efficiency between the electronic device 100 and the charging base 400.

[0212] For further information, see Fig.31 The third magnetic assembly 331 further includes a ninth magnetic portion 3313. The seventh magnetic portion 3311, the eighth magnetic portion 3312 and the ninth magnetic portion 3313 are arranged along the second direction X in sequence.

[0213] The ninth magnet portion 3313 has a magnetization direction along the first direction Z. In other words, the ninth magnet portion 3313 is a magnet, and further, the ninth magnet portion 3313 may be a permanent magnet after magnetization along the first direction Z. The end of the eighth magnet portion 3312 close to the ninth magnet portion 3313 has the same magnetism as the charging side of the ninth magnet portion 3313.
