Description

Electronic device for wirelessly charging batteries

[0001] Embodiments of the present disclosure relate to an electronic device for wirelessly charging a battery.

[0002] Electronic devices are striving for thinness, weight reduction, miniaturization, and multifunctionality. To achieve this, displays and various components are being incorporated into electronic devices. As display technology advances, research and development on electronic devices that incorporate displays (or flexible displays) are actively underway. Electronic devices may incorporate displays (or flexible displays), and digitizers may be applied to convert analog coordinates (e.g., position) from an electronic pen (e.g., a stylus pen) into digital data.

[0003] In a wireless charging system, a battery can be wirelessly charged using a coil. For example, a wireless charging system may include a power supply device (e.g., a charging pad or a charging cradle) having a plurality of transmitting coils and a power receiving device (e.g., a smartphone, a smartwatch, a wireless earphone charging case (or cradle)) having receiving coils.

[0004] The above-described material is provided solely as background information to aid in understanding the embodiments of the present disclosure. No determination has been made, and no claims are made, as to whether any of the above material constitutes prior art in connection with the present disclosure.

[0005] To improve the efficiency of the wireless charging method, the charging coil of the first electronic device (e.g., the wireless power receiving device) and the charging coil of the second electronic device (e.g., the wireless power transmitting device) must be aligned. The first electronic device (e.g., the wireless power receiving device) may include a magnetic part (e.g., a magnet part) arranged to surround the coil to align the coil.

[0006] The coils can be aligned (e.g., aligned to overlap in the z-axis direction) by the magnetic part (e.g., the magnet part). When the magnetic part (e.g., the magnet part) is placed in the wireless charging module, the coils can be aligned through magnetic engagement, thereby maintaining high charging efficiency. Although the charging efficiency is increased, the magnetic force generated by the magnetic part (e.g., the magnet part) may affect the electronic components of the electronic device. For example, the magnetic force generated by the magnetic part (e.g., the magnet part) itself may affect the operation of the digitizer and camera module placed in the electronic device.

[0007] One embodiment of the present disclosure can provide an electronic device in which a magnetic part (e.g., a magnet part, a magnet structure, a magnetic structure) is arranged so as not to affect the operation of a digitizer and a camera module arranged in the electronic device.

[0008] One embodiment of the present disclosure can provide an electronic device that can substantially eliminate (or reduce) the influence on the operation of a digitizer and a camera module due to a magnetic force generated from a magnetic part (e.g., a magnet part, a magnet structure, a magnetic structure) even when the magnetic part (e.g., a magnet part, a magnet structure, a magnetic structure) is arranged to surround a coil of a wireless charging module.

[0009] The technical challenges addressed in this document are not limited to the technical challenges mentioned above, and may be expanded upon without departing from the spirit and scope of the present disclosure. Additional technical challenges not mentioned herein will be readily apparent to those skilled in the art, as described below.

The wireless charging module may include a wireless charging power receiver induction coil having a bonding surface and a center perpendicular to the bonding surface, and a magnetic body disposed outside the wireless charging power receiver induction coil to align the wireless charging power transmitter induction coil and the wireless charging power receiver induction coil. The magnetic body may be arranged such that magnets having opposite polarities at a side closer to the center and a side farther from the center are perpendicular to the bonding surface. The magnetic body may be arranged such that magnets having different polarities at a side farther from the bonding surface are arranged in a U shape.

[0011] An electronic device according to one embodiment of the present disclosure may include a wireless charging module for charging a battery in a wireless charging manner. The wireless charging module may include a coil wound and arranged around a center point, a magnetic portion arranged to surround the coil, and a shield portion arranged on an upper portion of the magnetic portion. The magnetic portion may include a first magnet portion, a second magnet portion, and a third magnet portion. The first magnet portion may be arranged so as to form a first polarity and a second polarity opposite to the first polarity in a vertical direction of the electronic device. The second magnet portion may be arranged so as to form a first polarity and a second polarity opposite to the first polarity in a vertical direction of the electronic device at a predetermined interval from the first magnet portion. The third magnet portion may be arranged so as to form a first polarity and a second polarity opposite to the first polarity in a horizontal direction of the electronic device between the first magnet portion and the second magnet portion.

[0014] An electronic device according to an embodiment of the present disclosure can reduce a magnetic force directed in a vertical direction (e.g., z-axis direction) of an electronic device (e.g., wireless power receiving device) when a magnetic part is arranged to surround a coil. At this time, the alignment performance of the coil can be improved by maintaining (or improving) the pull force between the electronic device (e.g., wireless power receiving device) and the wireless power transmitting device.

[0015] An electronic device according to one embodiment of the present disclosure can reduce the influence on the operation of electronic components (e.g., a digitizer, a camera module) disposed inside an electronic device (e.g., a wireless power receiving device) by reducing the magnetic force directed in a vertical direction (e.g., a z-axis direction) of the electronic device (e.g., a wireless power receiving device) when applying a magnetic part arranged to surround a coil.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0061] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimizing terminal power and connecting multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)).

[0067] The embodiments of the present disclosure and the terminology used therein are not intended to limit the technical features described in this document to a specific embodiment, but should be understood to include various modifications, equivalents, or substitutes of the embodiment. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the item, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among the phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish the corresponding component from other corresponding components and do not limit the corresponding components in any other respect (e.g., importance or order). When a component (e.g., a first) is referred to as "coupled" or "connected" to another (e.g., a second) component, with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0068] The term "module" used in one embodiment of the present disclosure may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit, for example. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0069] An embodiment of the present disclosure may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (101)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (101)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0070] According to one embodiment, the method according to one embodiment disclosed in the present document may be provided as a computer program product. The computer program product may be traded between sellers and buyers as a product. The computer program product may be distributed in the form of a device-readable storage medium (e.g., compact disc read-only memory (CD-ROM)) or may be available through an application store (e.g., Play Store).

[0121] Fig. 4 is a drawing showing a wireless charging module arranged inside an electronic device. Fig. 5 is a drawing showing a coil and magnetic part of the wireless charging module.

[0122] Referring to FIGS. 4 and 5, an electronic device (400) according to an embodiment of the present disclosure may include a wireless charging module (410) for wirelessly charging a battery (e.g., battery (189) of FIG. 1).

[0123] According to one embodiment, the wireless charging module (410) may include a coil (411), a magnetic portion (412) (e.g., a magnet portion, a magnetic structure, a magnetic structure), feeding lines (413), and a flexible printed circuit board (FPCB) (414).

[0124] For example, the coil (411) may be arranged with the conductive wire wound around a center point to form a circle (or oval).

[0125] For example, the magnetic portion (412) (e.g., magnet portion, magnet structure, magnetic structure) may be arranged to surround the outer periphery of the coil (411) based on the center point along the shape of the coil (411) (e.g., circular or oval). By means of the magnetic portion (412) (e.g., magnet portion, magnet structure, magnetic structure), the coil (411) of the electronic device (400) and the coil arranged in the wired power transmission device (e.g., the second electronic device (202) of FIGS. 2 and 3) may be aligned (e.g., aligned to overlap in the z-axis direction). For example, the feeding lines (413) of the coil (411) may be arranged to overlap with the FPCB (414).

[0126] Figures 6 and 7 are drawings showing the structure of a wireless charging module of an electronic device.

[0127] Referring to FIGS. 6 and 7, the electronic device (400) may include a lower support portion (401), a support plate (402), and a metal shield portion (403) so that a wireless charging module (410) can be placed.

[0128] According to one embodiment, the wireless charging module (410) may include a coil (411) and a magnetic portion (412) (e.g., a magnet portion, a magnetic structure, a magnetic structure).

[0129] According to one embodiment, a wireless charging module (410) may be placed on top of a lower support member (401). The support plate (402) may include a circular (or oval) hole through which the wireless charging module (410) may be inserted. A shielding member (403) may be placed on top of the wireless charging module (410) to shield electromagnetic waves generated by the wireless charging module (410).

[0130] For example, the shielding portion (403) may include a first shielding layer (4031) (e.g., a magnetic shielding layer) and a second shielding layer (4032) (e.g., a metal shielding layer).

[0131] For example, a first shielding layer (4031) (e.g., a magnetic shielding layer) may be arranged adjacent to a magnetic portion (412) (e.g., a magnet portion, a magnet structure, a magnetic structure). A second shielding layer (4032) (e.g., a metal shielding layer) may be arranged on top of the first shielding layer (4031) (e.g., a magnetic shielding layer).

[0132] FIG. 8 and FIG. 9 are drawings showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0133] Referring to FIGS. 8 and 9, the magnetic portion (800) may include a first magnet (810), a second magnet (820), and a non-magnetic portion (830). The first magnet (810) may be arranged such that its first polarity (e.g., south pole) faces the -Z direction. The second magnet (820) may be arranged such that its second polarity (e.g., north pole) faces the -Z direction.

[0134] For example, the first magnet (810) and the second magnet (820) may be arranged in a circular (or oval) shape to surround a coil (e.g., coil (411) of FIG. 4) with the center point as the original. For example, the shape of the coil (411) is not limited to the circular or oval embodiment, and the coil (411) may be formed in various shapes (square, polygonal, etc.).

[0135] According to one embodiment, a non-magnetic portion (830) may be placed between the first magnet (810) and the second magnet (820).

[0136] For example, the first magnet (810) may be placed on the inside (e.g., inner side) with respect to the center point of the coil (411), and the second magnet (820) may be placed on the outside (e.g., outer side) of the first magnet (810). However, the present invention is not limited thereto, and the second magnet (820) may be placed on the inside (e.g., inner side) with respect to the center point of the coil (411), and the first magnet (810) may be placed on the outside (e.g., outer side) of the second magnet (820).

[0137] For example, with respect to a vertical axis (e.g., the z-axis of FIG. 6) of an electronic device (e.g., the electronic device (400) of FIGS. 4 and 6), the first magnet (810) and the second magnet (820) may be arranged (e.g., formed) in a single-layer structure.

[0138] For example, with respect to a vertical axis (e.g., the z-axis of FIG. 6) of an electronic device (e.g., the electronic device (400) of FIGS. 4 and 6), the first magnet (810) and the second magnet (820) may be arranged (e.g., formed) in a multi-layer structure.

[0139] Fig. 10 is a drawing (1000) showing a magnetic structure of a comparative example. Fig. 10 is a drawing showing a cross-section of a magnetic portion (1001) along the line B1-B2 of Fig. 9. Referring to Fig. 10, a magnetic portion (1001) of an electronic device (e.g., a wireless power receiving device, the first electronic device (201) of Fig. 2) and a magnetic portion (1002) of a wireless power transmitting device (e.g., the second electronic device (202) of Fig. 2)) may be arranged in a top-bottom magnetization manner. For example, the top-bottom magnetization manner may indicate a magnet magnetization form in which the N pole and the S pole of the magnet are divided into upper and lower parts.

[0140] For example, a non-magnetic zone (1040, non-magnetized zone) may be placed between the first magnet (1010) and the second magnet (1020) of the magnetic section (1001) of an electronic device (e.g., a wireless power receiving device). A shielding layer (1030) may be placed on top of the magnetic section (1001).

[0141] For example, the magnetic portion (1002) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be arranged to have polarities opposite to the polarities of the first magnet (1010) and the second magnet (1020) of the magnetic portion (1001) of the electronic device (e.g., the wireless power reception device). By the magnetic portion (1001) of the electronic device (e.g., the wireless power reception device) and the magnetic portion (1002) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2), the coil of the electronic device (e.g., the wireless power reception device) and the coil of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be aligned (e.g., aligned to overlap in the z-axis direction).

[0142] When the magnetic part (e.g., the magnetic part (1001) of FIG. 10) is arranged in the top-down manner of FIG. 10, the magnetic force is formed in a vertical direction, so the alignment performance with the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) is excellent, but the operation of electronic components (e.g., a digitizer) arranged inside the electronic device (e.g., a wireless power receiving device) may be affected.

[0143] Fig. 11 is a drawing (1100) showing the magnetic structure of a comparative example.

[0144] Referring to FIG. 11, the magnetic part (1101) of an electronic device (e.g., a wireless power receiving device, the first electronic device (201) of FIG. 2) and the magnetic part (1102) of a wireless power transmitting device (e.g., the second electronic device (202) of FIG. 2) may be arranged in a radial manner.

[0145] For example, the magnets (1110) of an electronic device (e.g., a wireless power receiver) may be arranged in a radial manner, and a separate shielding layer may not be arranged. For example, the radial manner may include a manner in which magnets are arranged radially from the center of a circle to facilitate magnetization. Not limited thereto, even if the magnetic portion (1101) of the electronic device (e.g., a wireless power receiver) is arranged in a radial manner, a shielding layer may be further included.

[0146] For example, the magnetic portion (1102) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be arranged to have a polarity opposite to that of the magnet (1110) of the electronic device (e.g., the wireless power reception device). By the magnetic portion (1101) of the electronic device (e.g., the wireless power reception device) and the magnetic portion (1102) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2), the coil of the electronic device (e.g., the wireless power reception device) and the coil of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be aligned (e.g., aligned to overlap in the z-axis direction).

[0147] Figure 12 is a drawing showing the influence of magnetic force generated in the magnetic part of the comparative example.

[0148] Referring to FIG. 12, when the magnetic part (e.g., the magnetic part (1101) of FIG. 11) is arranged in a radial manner as in FIG. 11, it is formed in vertical and horizontal directions and has little effect on the operation of electronic components (e.g., a digitizer) arranged inside an electronic device (e.g., a wireless power receiving device), but the alignment performance with the wireless power transmitting device (e.g., the second electronic device (202) of FIG. 2) may be reduced.

[0149] Fig. 13 is a drawing (1300) showing the structure of a magnetic part according to one embodiment of the present disclosure. Fig. 13 is a drawing showing a cross-section of a magnetic part (1301) along line B1-B2 of Fig. 9.

[0150] Referring to FIG. 13, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1301) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0151] According to one embodiment, a magnetic portion (1301) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (1310, 1320, 1340) and a non-magnetic portion (1350). A shield portion (1330) may be arranged on an upper portion of the magnetic portion (1301) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0152] According to one embodiment of the present disclosure, a magnetic portion (1301) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (1310, 1320, 1340) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0153] According to one embodiment, the magnetic portion (1301) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (1310), a second magnet portion (1320), and a third magnet portion (1340) (e.g., bridge magnet portion).

[0154] For example, the first magnet portion (1310) and the second magnet portion (1320) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0155] For example, the third magnet part (1340) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1301) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0156] For example, the first magnet portion (1310) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0157] For example, the second magnet portion (1320) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0158] For example, the magnetic portion (1302) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be arranged to have polarities opposite to the polarities of the first magnet portion (1310) and the second magnet portion (1320) of the magnetic portion (1301) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device). By the magnetic portion (1301) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device) and the magnetic portion (1302) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2)), the coil of the electronic device (e.g., the wireless power reception device) and the coil of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be aligned (e.g., aligned to overlap in the z-axis direction).

[0159] For example, the first magnet part (1310) and the second magnet part (1320) may be arranged at a certain interval. A third magnet part (1340) (e.g., a bridge magnet part) and a non-magnetic part (1350) may be arranged between the first magnet part (1310) and the second magnet part (1320).

[0160] For example, the first magnet portion (1310) and the second magnet portion (1320) may have substantially the same thickness.

[0161] For example, the third magnet portion (1340) (e.g., bridge magnet portion) may have a thinner thickness than the first magnet portion (1310) or the second magnet portion (1320).

[0162] For example, the third magnet portion (1340) (e.g., bridge magnet portion) may be arranged so that a first polarity (e.g., south pole) and a second polarity (e.g., north pole) are formed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0163] For example, the non-magnetic portion (1350) may be positioned below the third magnetic portion (1340). For example, the non-magnetic portion (1350) may be positioned adjacent to the magnetic portion (1302) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2).

[0164] For example, the third magnetic portion (1340) (e.g., bridge magnetic portion) may be placed on top of the non-magnetic portion (1350).

[0165] For example, when the magnetic portion (1301) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side surface (1311) of the first magnet portion (1310) and the first side surface (1341) of the third magnet portion (1340) (e.g., bridge magnet portion) may be arranged to overlap at least partially (e.g., to touch).

[0166] For example, when the magnetic portion (1301) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (1321) of the second magnet portion (1320) and the second side (1342) of the third magnet portion (1340) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch) at least a portion of the magnetic portion (1301).

[0167] For example, in Fig. 13, the first magnet portion (1310), the second magnet portion (1320), and the third magnet portion (1340) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (1310), the second magnet portion (1320), and the third magnet portion (1340) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

[0168] For example, a third magnet part (1340) (e.g., a bridge magnet part) may be placed between the first magnet part (1310) and the second magnet part (1320) so that the radiation direction of the magnetic force generated from the magnetic part (1301) itself may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400).

[0169] For example, the radiation direction of the magnetic force generated from the magnetic portion (1301) itself may be directed from the first magnet portion (1310) to the third magnet portion (1340) (e.g., bridge magnet portion), and from the third magnet portion (1340) (e.g., bridge magnet portion) to the second magnet portion (1320). Conversely, the radiation direction of the magnetic force generated from the magnetic portion (1301) itself may be directed from the second magnet portion (1320) to the third magnet portion (1340) (e.g., bridge magnet portion), and from the third magnet portion (1340) (e.g., bridge magnet portion) to the first magnet portion (1310).

[0170] FIG. 14 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0171] Referring to FIG. 14, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1400) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0172] According to one embodiment, a magnetic portion (1400) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (1410, 1420, 1440) and a non-magnetic portion (1450). A shield portion (1430) may be arranged on an upper portion of the magnetic portion (1400) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0173] According to one embodiment of the present disclosure, a magnetic portion (1400) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (1410, 1420, 1440) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0174] According to one embodiment, the magnetic portion (1400) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (1410), a second magnet portion (1420), and a third magnet portion (1440) (e.g., bridge magnet portion).

[0175] For example, the first magnet portion (1410) and the second magnet portion (1420) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0176] For example, the third magnet part (1440) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1400) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0177] For example, the first magnet portion (1410) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0178] For example, the second magnet portion (1420) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0179] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (1410) and a second magnetic portion (1420) of a magnetic portion (1400) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (1400) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0180] For example, the first magnet part (1410) and the second magnet part (1420) may be arranged at a certain interval. A non-magnetic part (1450) may be arranged between the first magnet part (1410) and the second magnet part (1420).

[0181] For example, the third magnet portion (1440) (e.g., bridge magnet portion) may be arranged so that a first polarity (e.g., south pole) and a second polarity (e.g., north pole) are formed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0182] For example, the non-magnetic portion (1450) may be positioned below the third magnetic portion (1440). For example, the non-magnetic portion (1450) may be positioned adjacent to a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2).

[0183] For example, the third magnet portion (1440) (e.g., bridge magnet portion) may be placed on top of the first magnet portion (1410), the second magnet portion (1420), and the non-magnetic portion (1450).

[0184] For example, when the magnetic part (1400) (e.g., magnet part, magnet structure, magnetic structure) is viewed in the vertical direction (e.g., z-axis direction) of the electronic device (400), the upper surface of the first magnet part (1410) and the lower surface of the third magnet part (1440) (e.g., bridge magnet part) may be arranged to overlap (e.g., touch).

[0185] For example, when the magnetic part (1400) (e.g., magnet part, magnet structure, magnetic structure) is viewed in the vertical direction (e.g., z-axis direction) of the electronic device (400), the upper surface of the second magnet part (1420) and the lower surface of the third magnet part (1440) (e.g., bridge magnet part) may be arranged to overlap (e.g., touch).

[0186] For example, the first magnet portion (1410) and the second magnet portion (1420) may have substantially the same thickness.

[0187] For example, the third magnet portion (1440) (e.g., bridge magnet portion) may have a thinner thickness than the first magnet portion (1410) or the second magnet portion (1420). However, this is not limited thereto.

[0188] The third magnet portion (1440) (e.g., bridge magnet portion) may be formed thicker than the first magnet portion (1410) or the second magnet portion (1420).

[0189] For example, in Fig. 14, the first magnet portion (1410), the second magnet portion (1420), and the third magnet portion (1440) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (1410), the second magnet portion (1420), and the third magnet portion (1440) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

[0190] For example, a third magnet portion (1440) (e.g., a bridge magnet portion) may be arranged on top of the first magnet portion (1410) and the second magnet portion (1420), so that the radiation direction of the magnetic force generated from the magnetic portion (1400) itself may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400).

[0191] For example, the radiation direction of the magnetic force generated from the magnetic portion (1400) itself may be directed from the first magnet portion (1410) to the third magnet portion (1440) (e.g., bridge magnet portion), and from the third magnet portion (1440) (e.g., bridge magnet portion) to the second magnet portion (1420). Conversely, the radiation direction of the magnetic force generated from the magnetic portion (1400) itself may be directed from the second magnet portion (1420) to the third magnet portion (1440) (e.g., bridge magnet portion), and from the third magnet portion (1440) (e.g., bridge magnet portion) to the first magnet portion (1410).

[0192] FIG. 15 is a drawing (1500) showing the influence of magnetic force generated in a magnetic part according to one embodiment of the present disclosure.

[0193] Referring to FIG. 15, when the magnetic part (1301) of FIG. 13 (e.g., magnet part, magnet structure, magnetic structure) or the magnetic part (1400) of FIG. 14 (e.g., magnet part, magnet structure, magnetic structure) is applied, the magnetic force directed in the vertical direction (e.g., z-axis direction) of the electronic device (e.g., wireless power receiving device) can be reduced. At this time, by maintaining (or improving) (e.g., full force = 11.34 N) the pull force between the electronic device (e.g., wireless power receiving device) and the wireless power transmitting device (e.g., the second electronic device (202) of FIG. 2), the alignment performance of the coil can be improved. In addition, when the magnetic part (1301) of FIG. 13 (e.g., magnet part, magnet structure, magnetic structure) or the magnetic part (1400) of FIG. 14 (e.g., magnet part, magnet structure, magnetic structure) is applied, the magnetic force directed in the vertical direction (e.g., z-axis direction) of the electronic device (e.g., wireless power receiving device) can be reduced, thereby reducing the influence on the operation of electronic components (e.g., digitizer, camera module) placed inside the electronic device (e.g., wireless power receiving device).

[0194] FIG. 16 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0195] Referring to FIG. 16, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1600) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0196] According to one embodiment, a magnetic portion (1600) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (1610, 1620, 1640) and a non-magnetic portion (1650). A shield portion (1630) may be arranged on an upper portion of the magnetic portion (1600) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0197] According to one embodiment of the present disclosure, a magnetic portion (1600) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (1610, 1620, 1640) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0198] According to one embodiment, the magnetic portion (1600) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (1610), a second magnet portion (1620), and a third magnet portion (1640) (e.g., bridge magnet portion).

[0199] For example, the first magnet portion (1610) and the second magnet portion (1620) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0200] For example, the third magnet part (1640) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1600) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0201] For example, the first magnet portion (1610) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0202] For example, the second magnet portion (1620) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0203] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (1610) and a second magnetic portion (1620) of a magnetic portion (1600) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (1600) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0204] For example, the first magnet portion (1610) and the second magnet portion (1620) may be arranged at a certain interval. A third magnet portion (1640) (e.g., a bridge magnet portion) and a non-magnetic portion (1650) may be arranged between the first magnet portion (1610) and the second magnet portion (1620).

[0205] For example, at least a portion of one side (1611) of the first magnet portion (1610) may be formed to be inclined at a certain angle (e.g., obliquely). For example, the cross-section of the first magnet portion (1610) may be formed in the shape of a pentagon (or a polygon other than a pentagon).

[0206] For example, at least a portion of one side (1621) of the second magnet portion (1620) may be formed to be inclined at a certain angle (e.g., obliquely). For example, the cross-section of the second magnet portion (1620) may be formed in the shape of a pentagon (or a polygon other than a pentagon).

[0208] For example, the first side (1641) of the third magnet portion (1640) (e.g., bridge magnet portion) may be formed to be inclined at a certain angle (e.g., obliquely). For example, the second side (1642) of the third magnet portion (1640) (e.g., bridge magnet portion) may be formed to be inclined at a certain angle (e.g., obliquely).

[0209] For example, the non-magnetic portion (1650) may be positioned below the third magnetic portion (1640).

[0210] For example, the third magnet portion (1640) (e.g., bridge magnet portion) may be placed on top of the non-magnetic portion (1650).

[0211] For example, when the magnetic portion (1600) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side surface (1611) of the first magnet portion (1610) and the first side surface (1641) of the third magnet portion (1640) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch). For example, the portion where at least a portion of one side surface (1611) of the first magnet portion (1610) and the first side surface (1641) of the third magnet portion (1640) (e.g., bridge magnet portion) touch may form an inclined surface.

[0212] For example, when the magnetic portion (1600) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (1621) of the second magnet portion (1620) and the second side (1642) of the third magnet portion (1640) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0214] For example, in FIG. 16, the first magnet portion (1610), the second magnet portion (1620), and the third magnet portion (1640) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (1610), the second magnet portion (1620), and the third magnet portion (1640) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

[0215] For example, a third magnet part (1640) (e.g., a bridge magnet part) may be placed between the first magnet part (1610) and the second magnet part (1620) so that the radiation direction of the magnetic force generated from the magnetic part (1600) itself may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400).

[0216] For example, the radiation direction of the magnetic force generated from the magnetic portion (1600) itself may be directed from the first magnet portion (1610) to the third magnet portion (1640) (e.g., bridge magnet portion), and from the third magnet portion (1640) (e.g., bridge magnet portion) to the second magnet portion (1620). Conversely, the radiation direction of the magnetic force generated from the magnetic portion (1600) itself may be directed from the second magnet portion (1620) to the third magnet portion (1640) (e.g., bridge magnet portion), and from the third magnet portion (1640) (e.g., bridge magnet portion) to the first magnet portion (1610).

[0217] FIG. 17 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0218] Referring to FIG. 17, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1700) (e.g., a magnet portion, a magnet structure, a magnetic structure).

A shield portion (1730) may be arranged on an upper portion of the magnetic portion (1700) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0220] According to one embodiment of the present disclosure, a magnetic portion (1700) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (1710, 1720, 1740) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0221] According to one embodiment, the magnetic portion (1700) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (1710), a second magnet portion (1720), and a third magnet portion (1740) (e.g., bridge magnet portion).

[0222] For example, the first magnet portion (1710) and the second magnet portion (1720) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0223] For example, the third magnet part (1740) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1700) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0224] For example, the first magnet portion (1710) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0225] For example, the second magnet portion (1720) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0226] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (1710) and a second magnetic portion (1720) of a magnetic portion (1700) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (1700) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0227] For example, the first magnet portion (1710) and the second magnet portion (1720) may be arranged at a certain interval. A third magnet portion (1740) (e.g., a bridge magnet portion) and a non-magnetic portion (1750) may be arranged between the first magnet portion (1710) and the second magnet portion (1720).

[0228] For example, the upper surface (1711) of the first magnet portion (1710) may be formed to be inclined at a certain angle (e.g., slanted). For example, the cross-section of the first magnet portion (1710) may be formed in the shape of a square (or a polygon other than a square).

[0229] For example, the upper surface (1721) of the second magnet portion (1720) may be formed to be inclined at a certain angle (e.g., slanted). For example, the cross-section of the second magnet portion (1720) may be formed in the shape of a square (or a polygon other than a square).

[0230] For example, the third magnet portion (1740) (e.g., bridge magnet portion) may be arranged so that a first polarity (e.g., south pole) and a second polarity (e.g., north pole) are formed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0231] For example, the first side (1741) of the third magnet portion (1740) (e.g., bridge magnet portion) may be formed to be inclined at a certain angle (e.g., obliquely). For example, the second side (1742) of the third magnet portion (1740) (e.g., bridge magnet portion) may be formed to be inclined at a certain angle (e.g., obliquely).

[0232] For example, the non-magnetic portion (1750) may be positioned below the third magnetic portion (1740). For example, the non-magnetic portion (1750) may be positioned adjacent to a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2).

[0233] For example, the third magnetic portion (1740) (e.g., bridge magnetic portion) may be placed on top of the non-magnetic portion (1750).

[0234] For example, when the magnetic portion (1700) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), the upper surface (1711) of the first magnet portion (1710) and the first side surface (1741) of the third magnet portion (1740) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch). For example, the portion where the upper surface (1711) of the first magnet portion (1710) and the first side surface (1741) of the third magnet portion (1740) (e.g., bridge magnet portion) touch may form an inclined surface.

[0235] For example, when the magnetic portion (1700) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), the upper surface (1721) of the second magnet portion (1720) and the second side surface (1742) of the third magnet portion (1740) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0236] For example, the part where the upper surface (1721) of the second magnet part (1720) and the second side surface (1742) of the third magnet part (1740) (e.g., bridge magnet part) come into contact can form an inclined surface.

[0237] For example, in Fig. 17, the first magnet portion (1710), the second magnet portion (1720), and the third magnet portion (1740) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (1710), the second magnet portion (1720), and the third magnet portion (1740) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

[0238] For example, a third magnet part (1740) (e.g., a bridge magnet part) may be placed between the first magnet part (1710) and the second magnet part (1720) so that the radiation direction of the magnetic force generated from the magnetic part (1700) itself may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400).

[0239] For example, the radiation direction of the magnetic force generated from the magnetic portion (1700) itself may be directed from the first magnet portion (1710) to the third magnet portion (1740) (e.g., bridge magnet portion), and from the third magnet portion (1740) (e.g., bridge magnet portion) to the second magnet portion (1720). Conversely, the radiation direction of the magnetic force generated from the magnetic portion (1700) itself may be directed from the second magnet portion (1720) to the third magnet portion (1740) (e.g., bridge magnet portion), and from the third magnet portion (1740) (e.g., bridge magnet portion) to the first magnet portion (1710).

[0240] Fig. 18 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0241] Referring to FIG. 18, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1800) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0242] According to one embodiment, a magnetic portion (1800) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (1810, 1820, 1840) and a non-magnetic portion (1850). A shield portion (1830) may be arranged on an upper portion of the magnetic portion (1800) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0243] According to one embodiment of the present disclosure, a magnetic portion (1800) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (1810, 1820, 1840) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0244] According to one embodiment, the magnetic portion (1800) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (1810), a second magnet portion (1820), and a third magnet portion (1840) (e.g., bridge magnet portion).

[0245] For example, the first magnet portion (1810) and the second magnet portion (1820) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0246] For example, the third magnet part (1840) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1800) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0247] For example, the first magnet portion (1810) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0248] For example, the second magnet portion (1820) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a vertical direction (e.g., z-axis direction) of the electronic device (400).

[0249] For example, the magnetic portion (1802) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be arranged to have polarities opposite to the polarities of the first magnet portion (1810) and the second magnet portion (1820) of the magnetic portion (1800) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device). By the magnetic portion (1800) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device) and the magnetic portion (1802) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2)), the coil of the electronic device (e.g., the wireless power reception device) and the coil of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be aligned (e.g., aligned to overlap in the z-axis direction).

[0250] For example, the first magnet portion (1810) and the second magnet portion (1820) may be arranged at a certain interval. A third magnet portion (1840) (e.g., a bridge magnet portion) and a non-magnetic portion (1850) may be arranged between the first magnet portion (1810) and the second magnet portion (1820).

[0251] For example, the first magnet portion (1810) and the second magnet portion (1820) may have the same thickness.

[0252] For example, the third magnet portion (1840) (e.g., bridge magnet portion) may have the same thickness as the first magnet portion (1810) or the second magnet portion (1820). However, the third magnet portion (1840) (e.g., bridge magnet portion) may be formed thicker than the first magnet portion (1810) or the second magnet portion (1820).

[0253] For example, a gap (1860) may be formed between the first magnet portion (1810) and the shield portion (1830) due to the thickness of the third magnet portion (1840) (e.g., bridge magnet portion). For example, a gap (1860) may be formed between the second magnet portion (1820) and the shield portion (1830) due to the thickness of the third magnet portion (1840) (e.g., bridge magnet portion).

[0254] For example, the gap (1860) between the first magnet portion (1810), the second magnet portion (1820), and the shield portion (1830) may be left as an empty space. Without being limited thereto, the gap (1860) between the first magnet portion (1810), the second magnet portion (1820), and the shield portion (1830) may be filled with a non-magnetic material.

[0255] For example, the third magnet portion (1840) (e.g., bridge magnet portion) may be arranged so that a first polarity (e.g., south pole) and a second polarity (e.g., north pole) are formed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0256] For example, the non-magnetic portion (1850) may be positioned below the third magnetic portion (1840). For example, the non-magnetic portion (1850) may be positioned adjacent to the magnetic portion (1802) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2).

[0257] For example, the third magnet section (1840) (e.g., bridge magnet section) may be placed on top of the non-magnetic section (1850).

[0258] For example, when the magnetic portion (1800) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (1811) of the first magnet portion (1810) and at least a portion of the first side (1841) of the third magnet portion (1840) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0259] For example, when the magnetic portion (1800) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (1821) of the second magnet portion (1820) and at least a portion of the second side (1842) of the third magnet portion (1840) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0260] For example, in FIG. 18, the first magnet portion (1810), the second magnet portion (1820), and the third magnet portion (1840) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (1810), the second magnet portion (1820), and the third magnet portion (1840) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may be directed toward the horizontal direction (e.g., the x-axis direction or the y-axis direction) of the electronic device (400).

[0262] For example, the radiation direction of the magnetic force generated from the magnetic portion (1800) itself may be directed from the first magnet portion (1810) to the third magnet portion (1840) (e.g., bridge magnet portion), and from the third magnet portion (1840) (e.g., bridge magnet portion) to the second magnet portion (1820).

[0263] FIG. 19 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0264] Referring to FIG. 19, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (1900) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0265] According to one embodiment, a magnetic portion (1900) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (1910, 1920, 1940) and a non-magnetic portion (1950). A shield portion (1930) may be arranged on an upper portion of the magnetic portion (1900) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0268] For example, the first magnet portion (1910) and the second magnet portion (1920) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0269] For example, the third magnet part (1940) (e.g., bridge magnet part) may be arranged to form the radiation direction of the magnetic force generated from the magnetic part (1900) (e.g., magnet part, magnet structure, magnetic structure) itself in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., x-axis or y-axis direction of FIG. 6).

[0272] For example, the magnetic portion (1902) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be arranged to have polarities opposite to the polarities of the first magnet portion (1910) and the second magnet portion (1920) of the magnetic portion (1900) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device). By the magnetic portion (1900) (e.g., the magnet portion, the magnet structure, the magnetic structure) of the electronic device (e.g., the wireless power reception device) and the magnetic portion (1902) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2)), the coil of the electronic device (e.g., the wireless power reception device) and the coil of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2) may be aligned (e.g., aligned to overlap in the z-axis direction).

[0273] For example, the first magnet portion (1910) and the second magnet portion (1920) may be arranged at a certain interval. A third magnet portion (1940) (e.g., a bridge magnet portion) and a non-magnetic portion (1950) may be arranged between the first magnet portion (1910) and the second magnet portion (1920).

For example, a gap may be formed between the second magnet portion (1920) and the shield portion (1930) due to the thickness of the third magnet portion (1940) (e.g., bridge magnet portion).

[0277] For example, a structure (1960) identical to the shield (1930) (e.g., a shield) can be placed in the gap between the first magnet section (1910) and the second magnet section (1920) and the shield (1930).

[0278] As another example, a structure (1960) identical to the non-magnetic layer (1950) (e.g., a non-magnetic layer) may be placed in the gap between the first magnet portion (1910), the second magnet portion (1920), and the shield portion (1930).

[0288] FIG. 20 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0289] Referring to FIG. 20, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (2000) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0290] According to one embodiment, a magnetic portion (2000) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (2010, 2020) and a non-magnetic portion (2050). A shield portion (2030) may be arranged on an upper portion of the magnetic portion (2000) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0291] According to one embodiment of the present disclosure, a magnetic portion (2000) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (2010, 2020) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0292] According to one embodiment, the magnetic portion (2000) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (2010) and a second magnet portion (2020).

[0293] For example, the first magnet portion (2010) and the second magnet portion (2020) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0294] For example, the first magnet part (2010) and the second magnet part (2020) may be arranged so as to form the radiation direction of the magnetic force generated from the magnetic part (2000) itself (e.g., the magnet part, the magnet structure, the magnetic structure) in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., the x-axis or y-axis direction of FIG. 6).

[0295] For example, the first magnet portion (2010) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0296] For example, the first magnet portion (2010) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a first diagonal direction (2015) (e.g., upward direction in FIG. 20) that is offset by a certain angle with respect to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0297] For example, the first magnet portion (2010) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a first diagonal direction (2015) (e.g., upward direction in FIG. 20) that is offset by a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0298] For example, the second magnet portion (2020) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0299] For example, the second magnet portion (2020) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a second diagonal direction (2025) (e.g., downward direction in FIG. 20) that is offset by a certain angle with respect to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0300] For example, the second magnet portion (2020) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a second diagonal direction (2025) (e.g., downward right direction in FIG. 20) that is offset by a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0301] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (2010) and a second magnetic portion (2020) of a magnetic portion (2000) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (2000) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0302] For example, the first magnet part (2010) and the second magnet part (2020) may be arranged at a certain interval. A non-magnetic part (2050) may be arranged between the first magnet part (2010) and the second magnet part (2020).

[0303] For example, the width of the first magnetic portion (2010) and the width of the non-magnetic portion (2050) may be substantially the same. For example, the width of the non-magnetic portion (2050) may be wider than the width of the first magnetic portion (2010).

[0304] For example, the width of the second magnetic portion (2020) and the width of the non-magnetic portion (2050) may be substantially the same. For example, the width of the non-magnetic portion (2050) may be wider than the width of the second magnetic portion (2010).

[0305] For example, the non-magnetic portion (2050) may be positioned below the shielding portion (2030). For example, the non-magnetic portion (2050) may be positioned adjacent to a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2).

[0306] For example, the first magnet portion (2010) and the second magnet portion (2020) may have the same thickness.

[0307] For example, in Fig. 20, the first magnet portion (2010) and the second magnet portion (2020) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (2010) and the second magnet portion (2020) may be formed to have a rounded shape.

[0308] For example, the magnetic directions of the first magnet portion (2010) and the second magnet portion (2020) may be arranged to face a diagonal (e.g., oblique) direction that is at a certain angle with respect to the z-axis, so that the radiation direction of the magnetic force generated from the magnetic portion (2000) itself may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0309] For example, the radiation direction of the magnetic force generated from the magnetic part (2000) itself may be directed from the first magnet part (2010) to the shield part (2030), and from the shield part (2030) to the second magnet part (2020). Conversely, the radiation direction of the magnetic force generated from the magnetic part (2000) itself may be directed from the second magnet part (2020) to the shield part (2030), and from the shield part (2030) to the first magnet part (2010).

[0310] FIG. 21 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0311] Referring to FIG. 21, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (2100) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0312] According to one embodiment, a magnetic portion (2100) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (2110, 2120, 2140) and a non-magnetic portion (2150). A shield portion (2130) may be arranged on an upper portion of the magnetic portion (2100) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0313] According to one embodiment of the present disclosure, a magnetic portion (2100) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (2110, 2120) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0314] According to one embodiment, the magnetic portion (2100) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (2110), a second magnet portion (2120), and a third magnet portion (2140) (e.g., bridge magnet portion).

[0315] For example, the first magnet portion (2110) and the second magnet portion (2120) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (212) of FIG. 2).

[0316] For example, the first magnet portion (2110), the second magnet portion (2120), and the third magnet portion (2140) (e.g., the bridge magnet portion) may be arranged so that the direction of radiation of the magnetic force generated from the magnetic portion (2100) itself (e.g., the magnet portion, the magnet structure, the magnetic structure) is formed in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., the x-axis or y-axis direction of FIG. 6).

[0317] For example, the first magnet portion (2110) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0318] For example, the first magnet portion (2110) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle relative to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0319] For example, the first magnet portion (2110) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0320] For example, the second magnet portion (2120) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0321] For example, the second magnet portion (2120) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle with respect to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0322] For example, the second magnet portion (2120) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0323] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (212) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (2110) and a second magnetic portion (2120) of a magnetic portion (2100) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (2100) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (212) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (212) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0324] For example, the first magnet part (2110) and the second magnet part (2120) may be arranged at a certain interval. A third magnet part (2140) (e.g., a bridge magnet part) and a non-magnetic part (2150) may be arranged between the first magnet part (2110) and the second magnet part (2120).

[0325] For example, the non-magnetic portion (2150) may be positioned below the shielding portion (2130). For example, the non-magnetic portion (2150) may be positioned adjacent to a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (212) of FIG. 2).

[0326] For example, the first magnet portion (2110) and the second magnet portion (2120) may have the same thickness.

[0327] For example, the third magnet portion (2140) (e.g., bridge magnet portion) may have a thinner thickness than the first magnet portion (2110) or the second magnet portion (2120).

[0328] For example, the third magnet portion (2140) (e.g., bridge magnet portion) may be arranged so that a first polarity (e.g., south pole) and a second polarity (e.g., north pole) are formed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0329] For example, the non-magnetic portion (2150) may be positioned below the third magnetic portion (2140) (e.g., bridge magnetic portion). For example, the non-magnetic portion (2150) may be positioned adjacent to the magnetic portion (1302) of the wireless power transmission device (e.g., the second electronic device (202) of FIG. 2).

[0330] For example, the third magnetic portion (2140) (e.g., bridge magnetic portion) may be placed on top of the non-magnetic portion (2150).

[0331] For example, when the magnetic portion (2100) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (2111) of the first magnet portion (2110) and the first side (2141) of the third magnet portion (2140) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0332] For example, when the magnetic portion (2100) (e.g., magnet portion, magnet structure, magnetic structure) is viewed in a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400), at least a portion of one side (2121) of the second magnet portion (2120) and the second side (2142) of the third magnet portion (2140) (e.g., bridge magnet portion) may be arranged to overlap (e.g., touch).

[0333] For example, in Fig. 21, the first magnet portion (2110), the second magnet portion (2120), and the third magnet portion (2140) (e.g., the bridge magnet portion) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (2110), the second magnet portion (2120), and the third magnet portion (2130) (e.g., the bridge magnet portion) may be formed to have a rounded shape.

[0334] For example, the magnetic force directions of the first magnet portion (2110) and the second magnet portion (2120) may be arranged to face a diagonal (e.g., oblique) direction that is offset by a certain angle with respect to the z-axis, so that the radiation direction of the magnetic force generated from the magnetic portion (2100) itself may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0335] For example, the radiation direction of the magnetic force generated from the magnetic portion (2100) itself may be directed from the first magnet portion (2110) to the third magnet portion (2140) (e.g., bridge magnet portion), and from the third magnet portion (2140) (e.g., bridge magnet portion) to the second magnet portion (2120). Conversely, the radiation direction of the magnetic force generated from the magnetic portion (2100) itself may be directed from the second magnet portion (2120) to the third magnet portion (2140) (e.g., bridge magnet portion), and from the third magnet portion (2140) (e.g., bridge magnet portion) to the first magnet portion (2110).

[0336] FIG. 22 is a drawing showing the structure of a magnetic part according to one embodiment of the present disclosure.

[0337] Referring to FIG. 22, a wireless charging module (e.g., a wireless charging module (410) of FIG. 4) of an electronic device of the present disclosure (e.g., an electronic device (101) of FIG. 1, an electronic device (400) of FIG. 4) may include a magnetic portion (2200) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0338] According to one embodiment, a magnetic portion (2200) (e.g., a magnet portion, a magnet structure, a magnetic structure) according to one embodiment of the present disclosure may include a plurality of magnet portions (2210, 2220) and a non-magnetic portion (2250). A shield portion (2230) may be arranged on an upper portion of the magnetic portion (2200) (e.g., a magnet portion, a magnet structure, a magnetic structure).

[0339] According to one embodiment of the present disclosure, a magnetic portion (2200) (e.g., a magnet portion, a magnet structure, a magnetic structure) may be configured such that a plurality of magnet portions (2210, 2220) are arranged in a composite shape (e.g., a 'U' or 'V' shape).

[0340] According to one embodiment, the magnetic portion (2200) (e.g., magnet portion, magnet structure, magnetic structure) may include a first magnet portion (2210) and a second magnet portion (2220).

[0341] For example, the first magnet portion (2210) and the second magnet portion (2220) can be arranged to align a coil (e.g., coil (411) of FIG. 5) of an electronic device (e.g., wireless power receiving device) and a coil of a wireless power transmitting device (e.g., second electronic device (202) of FIG. 2).

[0342] For example, the first magnet part (2210) and the second magnet part (2220) may be arranged so as to form the radiation direction of the magnetic force generated from the magnetic part (2200) itself (e.g., the magnet part, the magnet structure, the magnetic structure) in the horizontal direction (x-axis or y-axis direction) of the electronic device (400) (e.g., the x-axis or y-axis direction of FIG. 6).

[0343] For example, the first magnet portion (2210) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0344] For example, the first magnet portion (2210) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle relative to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0345] For example, the first magnet portion (2210) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed in a diagonal direction (e.g., upward direction in FIG. 22) that is offset by a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0346] For example, the second magnet portion (2220) may be arranged so that a first polarity (e.g., S pole) and a second polarity (e.g., N pole) are formed at a predetermined angle (e.g., an oblique angle) between a vertical direction (e.g., z-axis direction) and a vertical direction (e.g., x-axis or y-axis direction) of the electronic device (400).

[0347] For example, the second magnet portion (2220) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction (e.g., downward direction in FIG. 22) that is offset by a certain angle with respect to the vertical direction (e.g., z-axis direction) of the electronic device (400).

[0348] For example, the second magnet portion (2220) may be arranged so that the first polarity (e.g., S pole) and the second polarity (e.g., N pole) are formed in a diagonal direction at a certain angle with respect to the horizontal direction (x-axis or y-axis direction) of the electronic device (400).

[0349] For example, a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2) may be arranged so as to have a polarity opposite to the polarity of a first magnetic portion (2210) and a second magnetic portion (2220) of a magnetic portion (2200) (e.g., a magnet portion, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device). By means of a magnetic part (2200) (e.g., a magnet part, a magnet structure, a magnetic structure) of an electronic device (e.g., a wireless power receiving device) and a magnetic part (1302) of a wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2), a coil of the electronic device (e.g., a wireless power receiving device) and a coil of the wireless power transmitting device (e.g., a second electronic device (202) of FIG. 2) can be aligned (e.g., aligned to overlap in the z-axis direction).

[0350] For example, the first magnet part (2210) and the second magnet part (2220) may be arranged at a certain interval. The width between the first magnet part (2210) and the second magnet part (2220) may be formed narrower than the width of the first magnet part (2210) or the second magnet part (2220).

[0351] For example, a non-magnetic portion (2250) may be placed between the first magnetic portion (2210) and the second magnetic portion (2220).

[0352] For example, the width of the non-magnetic portion (2250) may be formed narrower than the width of the first magnetic portion (2210).

[0353] For example, the width of the non-magnetic portion (2250) may be formed narrower than the width of the second magnetic portion (2220).

[0354] For example, the non-magnetic portion (2250) may be positioned below the shielding portion (2230). For example, the non-magnetic portion (2250) may be positioned adjacent to a magnetic portion (e.g., a magnetic portion (1302) of FIG. 13) of a wireless power transmission device (e.g., a second electronic device (202) of FIG. 2).

[0355] For example, the first magnet portion (2210) and the second magnet portion (2220) may have the same thickness.

[0356] For example, in FIG. 20, the first magnet portion (2210) and the second magnet portion (2220) are illustrated as having an angular shape. However, the present invention is not limited thereto, and the corner portions of the first magnet portion (2210) and the second magnet portion (2220) may be formed to have a rounded shape.

[0357] For example, the magnetic force directions of the first magnet portion (2210) and the second magnet portion (2220) may be arranged to face a diagonal (e.g., oblique) direction that is offset by a certain angle with respect to the z-axis, so that the radiation direction of the magnetic force generated from the magnetic portion (2200) itself may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400). In addition, the radiation direction of the magnetic force generated from the wireless charging module (410) may face a horizontal direction (e.g., x-axis direction or y-axis direction) of the electronic device (400).

[0358] For example, the radiation direction of the magnetic force generated from the magnetic part (2200) itself may be directed from the first magnet part (2210) to the shield part (2230), and from the shield part (2230) to the second magnet part (2220). Conversely, the radiation direction of the magnetic force generated from the magnetic part (2200) itself may be directed from the second magnet part (2220) to the shield part (2230), and from the shield part (2230) to the first magnet part (2210).

[0359] FIG. 23 is a drawing (2300) showing the influence of magnetic force generated in a magnetic part according to one embodiment of the present disclosure.

[0360] Referring to FIG. 23, when applying the magnetic part (1600) of FIG. 16, the magnetic part (1700) of FIG. 17, the magnetic part (1800) of FIG. 18, the magnetic part (1900) of FIG. 19, the magnetic part (2000) of FIG. 20, or the magnetic part (2100) of FIG. 21, the magnetic force directed in the vertical direction (e.g., z-axis direction) of the electronic device (e.g., wireless power receiving device) can be reduced. At this time, by maintaining (or improving) (e.g., full force = 8.63 N) the pull force between the electronic device (e.g., wireless power receiving device) and the wireless power transmitting device (e.g., the second electronic device (202) of FIG. 2), the alignment performance of the coil can be improved. In addition, when applying the magnetic part (1600) of FIG. 16, the magnetic part (1700) of FIG. 17, the magnetic part (1800) of FIG. 18, the magnetic part (1900) of FIG. 19, the magnetic part (2000) of FIG. 20, or the magnetic part (2100) of FIG. 21, the magnetic force directed in the vertical direction (e.g., z-axis direction) of the electronic device (e.g., wireless power receiving device) can be reduced, thereby reducing the influence on the operation of electronic components (e.g., digitizer, camera module) placed inside the electronic device (e.g., wireless power receiving device).

[0361] An electronic device according to one embodiment of the present disclosure may include a wireless charging module (e.g., a wireless charging module (410) of FIGS. 4 and 5) that charges a battery in a wireless charging manner.

The magnetic body portion (412, 1301, 1400, 1600, 1700, 1800, 1900, 2000, 2100, 2200) may be arranged so that magnets having opposite polarities on the side closer to the center and the side farther from the center are perpendicular to the bonding surface. The magnetic body portion (412, 1301, 1400, 1600, 1700, 1800, 1900, 2000, 2100, 2200) may be arranged so that magnets having different polarities on the side farther from the bonding surface are connected in a U shape.

[0362] According to one embodiment, at least a portion of the magnetic portion (412, 1301, 1400, 1600, 1700, 1800, 1900, 2000, 2100, 2200) may be arranged to protrude toward the bonding surface.

[0363] According to one embodiment, at least a portion of the magnetic portion (412, 1301, 1400, 1600, 1700, 1800, 1900, 2000, 2100, 2200) may be arranged to be recessed from the bonding surface.
