DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0034] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] It should be noted that, for the convenience of explanation, in the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0036] Wireless charging devices are used to charge electronic devices (such as mobile phones and tablets). The wireless charging device (transmitter) transmits energy through its coil with the coil of the electronic device (receiver), thereby achieving wireless charging. In order to better align the coil of the wireless charging device with the coil of the electronic device, it is usually necessary to set a magnet on the wireless charging device to adsorb the electronic device on the wireless charging device, thereby avoiding misalignment between the coil of the wireless charging device and the coil of the electronic device, which affects the charging efficiency and charging rate of the wireless charging device. However, the interference signal generated by the magnet in the related art is too large, which reduces the charging power of the wireless charging device.

[0037] Figure 1 1 is a schematic structural diagram of a wireless charging device 100 according to an embodiment of the present application. Figure 2 FIG. 1 is a schematic diagram of an exploded structure of a wireless charging device 100 according to an embodiment of the present application. Figure 3 2 is a structural diagram of the wireless charging device 100 from another perspective according to an embodiment of the present application. Figure 4 1 is a schematic diagram of an exploded structure of the wireless charging device 100 according to an embodiment of the present application from another perspective. Figure 5 2 is a schematic structural diagram of a magnetic assembly 20 according to an embodiment of the present application.

[0038] See Figures 1 to 5 The present application provides a wireless charging device 100, which includes: a wireless charging module 10 and a magnetic component 20, wherein the magnetic component 20 includes a plurality of magnetic sub-components 21, and the plurality of magnetic sub-components 21 are arranged at intervals along the periphery of the wireless charging module 10. The magnetic sub-component 21 includes a first magnetic member 211 and a second magnetic member 212, and the first magnetic member 211 and the second magnetic member 212 are arranged along the radial direction of the wireless charging module 10 (such as Figure 5 The first magnetic member 211 is arranged between the second magnetic member 212 and the wireless charging module 10. The arrangement direction of the magnetic poles of the first magnetic member 211 and the arrangement direction of the magnetic poles of the second magnetic member 212 are respectively parallel to the axial direction of the wireless charging module 10 (as shown by the double arrow X). Figure 5 As shown by the double arrow Y), the arrangement direction of the magnetic poles of the first magnetic member 211 is opposite to the arrangement direction of the magnetic poles of the second magnetic member 212, wherein the axial direction of the wireless charging module 10 is parallel to the thickness direction of the wireless charging device 100.

[0039] The wireless charging device 100 of the embodiment of the present application can be used to wirelessly charge portable electronic devices such as mobile phones, tablet computers, smart watches, smart watches, laptop computers, smart bracelets, e-readers, and game consoles. When the wireless charging device 100 is used to charge an electronic device, the electronic device is placed on the surface of the wireless charging device 100 (i.e., the electronic device is placed in contact with the wireless charging device 100), and the magnetic component 20 is used to adsorb the electronic device on the wireless charging device 100, so that the coil of the wireless charging module 10 is arranged to correspond to the coil of the electronic device.

[0040] Optionally, the wireless charging module 10 may be, but is not limited to, a sheet-like structure. Optionally, the sheet-like structure may be, but is not limited to, a circular or elliptical shape.

[0041] Optionally, the extension plane of the wireless charging module 10 is perpendicular to the thickness direction of the wireless charging device 100. It can be understood that the radial direction of the wireless charging module 10 is perpendicular to the thickness direction of the wireless charging device 100.

[0042] It should be noted that the wireless charging module 10 is used to electrically connect to an external power source to load an electrical signal (such as voltage or current) and transmit energy to charge the electronic device.

[0043] It can be understood that the plurality of magnetic subassemblies 21 are arranged along the circumferential direction of the wireless charging module 10 (eg Figure 5 Double arrow Z) interval setting.

[0044] Optionally, in the wireless charging device 100, the wireless charging module 10 and the magnetic assembly 20 are disposed in the same layer, that is, along the thickness direction of the wireless charging device 100, the wireless charging module 10 and the magnetic assembly 20 are disposed in the same layer. It should be noted that in other embodiments, the wireless charging module 10 and the magnetic assembly 20 are not disposed in the same layer, that is, they are staggered or spaced apart along the thickness direction of the wireless charging device 100.

[0045] Optionally, the plurality of magnetic subassemblies 21 are arranged in a circular shape.

[0046] Optionally, the magnetic subassembly 21 may be, but is not limited to, a magnet or other magnetic body.

[0047] It can be understood that the first magnetic member 211 is closer to the wireless charging module 10 than the second magnetic member 212 , and the second magnetic member 212 is farther from the wireless charging module 10 than the first magnetic member 211 .

[0048] The arrangement direction of the magnetic poles of the first magnetic member 211 and the arrangement direction of the magnetic poles of the second magnetic member 212 are respectively parallel to the axial direction of the wireless charging module 10. It can be understood that the magnetization direction of the first magnetic member 211 is parallel to the axial direction of the wireless charging module 10, and the magnetization direction of the second magnetic member 212 is parallel to the axial direction of the wireless charging module 10.

[0049] Optionally, the first magnetic member 211 may be, but is not limited to, a magnet or other magnetic body. The second magnetic member 212 may be, but is not limited to, a magnet or other magnetic body.

[0050] The wireless charging device 100 of the present application includes a wireless charging module 10 and a magnetic assembly 20. The magnetic assembly 20 includes multiple magnetic subassemblies 21, which are spaced apart along the periphery of the wireless charging module 10. Compared to using a single magnetic piece, the embodiment of the present application combines the magnetic assembly 20 by arranging multiple magnetic subassemblies 21 at intervals. This can reduce the magnetic field strength of the magnetic assembly 20, thereby reducing the interference of the magnetic field generated by the magnetic assembly 20 on the wireless charging module 10. This allows the wireless charging device 100 to have greater charging power, thereby better improving the charging efficiency and charging speed of the wireless charging device 100 and enhancing the user experience.

[0051] In addition, the magnetic subassembly 21 includes a first magnetic member 211 and a second magnetic member 212. The first magnetic member 211 and the second magnetic member 212 are arranged along the radial direction of the wireless charging module 10, and the first magnetic member 211 is located between the second magnetic member 212 and the wireless charging module 10. The arrangement direction of the magnetic poles of the first magnetic member 211 and the arrangement direction of the magnetic poles of the second magnetic member 212 are respectively parallel to the axial direction of the wireless charging module 10, and the arrangement direction of the magnetic poles of the first magnetic member 211 is opposite to the arrangement direction of the magnetic poles of the second magnetic member 212. Compared with the radial arrangement direction of the magnetic poles of the first magnetic component 211 and the radial arrangement direction of the magnetic poles of the second magnetic component 212, the arrangement directions of the magnetic poles of the first magnetic component 211 and the second magnetic component 212 in this embodiment are both parallel to the axial direction, so that the magnetic sub-component 21 has a greater magnetic attraction force, thereby further improving the adsorption performance of the magnetic component 20, so that the wireless charging device 100 can better adsorb the electronic device when used to charge the electronic device, and the coil of the wireless charging device 100 and the coil of the electronic device can be more accurately aligned.

[0052] Figure 6 Schematic diagram of the magnetic pole arrangement of the magnetic subassembly 21 according to an embodiment of the present application. Figure 7 Schematic diagram of the structure of the magnetic pole arrangement of the magnetic subassembly 21 of another embodiment of the present application.

[0053] See Figure 6 In some embodiments, along the axial direction of the wireless charging module 10, the first magnetic member 211 includes a first magnetic pole 2111 and a second magnetic pole 2112 disposed opposite to each other, and the second magnetic member 212 includes a third magnetic pole 2121 and a fourth magnetic pole 2122 disposed opposite to each other, the first magnetic pole 2111 is adjacent to the third magnetic pole 2121, and the second magnetic pole 2112 is adjacent to the fourth magnetic pole 2122; the direction of the magnetic force lines inside the first magnetic member 211 is from the first magnetic pole 2111 to the second magnetic pole 2112, and the direction of the magnetic force lines inside the second magnetic member 212 is from the fourth magnetic pole 2122 to the third magnetic pole 2121.

[0054] Optionally, the first magnetic member 211 is fitted with the second magnetic member 212. It is understandable that the first magnetic member 211 and the second magnetic member 212 abut against each other, and the first magnetic member 211 and the second magnetic member 212 are magnetically connected.

[0055] It is understood that the arrangement direction of the first magnetic pole 2111 and the second magnetic pole 2112 is perpendicular to the arrangement direction of the first magnetic member 211 and the second magnetic member 212. The arrangement direction of the third magnetic pole 2121 and the fourth magnetic pole 2122 is perpendicular to the arrangement direction of the first magnetic member 211 and the second magnetic member 212. It is also understood that the first magnetic pole 2111 and the second magnetic pole 2112 are arranged along the thickness direction of the wireless charging device 100, and the third magnetic pole 2121 and the fourth magnetic pole 2122 are arranged along the thickness direction of the wireless charging device 100.

[0056] It can be understood that in this embodiment, the first magnetic pole 2111 is a south pole (S), the second magnetic pole 2112 is a north pole (N), the third magnetic pole 2121 is a north pole (N), and the fourth magnetic pole 2122 is a south pole (S).

[0057] In this embodiment, the direction of the magnetic force lines within the first magnetic member 211 is directed from the first magnetic pole 2111 to the second magnetic pole 2112, and the direction of the magnetic force lines within the second magnetic member 212 is directed from the fourth magnetic pole 2122 to the third magnetic pole 2121. This allows the magnetic subassembly to have a greater magnetic attraction, thereby further improving the adsorption performance of the magnetic assembly. This allows the wireless charging device 100 to better attract the electronic device when used to charge the electronic device, and allows the coil of the wireless charging device 100 to be more accurately aligned with the coil of the electronic device.

[0058] See Figure 7In other embodiments, the direction of the magnetic lines of force inside the first magnetic member 211 is from the second magnetic pole 2112 to the first magnetic pole 2111 , and the direction of the magnetic lines of force inside the second magnetic member 212 is from the third magnetic pole 2121 to the fourth magnetic pole 2122 .

[0059] It can be understood that in this embodiment, the first magnetic pole 2111 is a north pole (N), the second magnetic pole 2112 is a south pole (S), the third magnetic pole 2121 is a south pole (S), and the fourth magnetic pole 2122 is a north pole (N).

[0060] In this embodiment, by making the direction of the magnetic lines of force inside the first magnetic member 211 point from the second magnetic pole 2112 to the first magnetic pole 2111, and the direction of the magnetic lines of force inside the second magnetic member 212 point from the third magnetic pole 2121 to the fourth magnetic pole 2122, the magnetic sub-assembly has a greater magnetic attraction, thereby further improving the adsorption performance of the magnetic assembly, so that when the wireless charging device 100 is used to charge the electronic device, it can better adsorb the electronic device, and the coil of the wireless charging device 100 and the coil of the electronic device can be more accurately aligned.

[0061] It should be noted that the first magnetic member 211 and the second magnetic member 212 are Figure 6 The solution is to use Figure 7 The solution can be adjusted according to the magnetic pole arrangement of the magnetic assembly of the electronic device.

[0062] Figure 8 FIG. 2 is a schematic planar structural diagram of a magnetic component 20 according to an embodiment of the present application. Figure 9 FIG. 2 is a schematic planar structural diagram of a magnetic component 20 according to another embodiment of the present application.

[0063] like Figure 8 As shown, in some embodiments, the first magnetic member 211 and the second magnetic member 212 are both in the shape of a rectangular parallelepiped. Figure 9 As shown, in some other embodiments, the first magnetic member 211 and the second magnetic member 212 are both arc-shaped.

[0064] It can be understood that when the first magnetic part 211 and the second magnetic part 212 are both arc-shaped, the surface of the first magnetic part 211 facing the second magnetic part 212 and the surface of the second magnetic part 212 facing the first magnetic part 211 are complementary in structure, so that the surface of the first magnetic part 211 facing the second magnetic part 212 and the surface of the second magnetic part 212 facing the first magnetic part 211 can fit tightly.

[0065] It should be noted that when the first magnetic member 211 and the second magnetic member 212 are both cuboid, the magnetic subassembly 21 is cuboid. When the first magnetic member 211 and the second magnetic member 212 are both arc-shaped, the magnetic subassembly 21 is arc-shaped as a whole.

[0066] Optionally, the arc shape may be, but is not limited to, a circular arc shape, an elliptical arc shape, a quasi-circular arc shape, or a quasi-elliptical arc shape.

[0067] In this embodiment, the use of a rectangular or arc-shaped first magnetic member 211 and a second magnetic member 212 can better reduce the magnetic field strength of the magnetic assembly 20 while increasing the magnetic attraction of the magnetic assembly 20. This can maximize the magnetic attraction of the magnetic assembly 20 and improve the adsorption force of the magnetic assembly 20 on the electronic device while reducing the interference of the magnetic assembly 20 on the wireless charging module 10. In addition, compared to a solution in which both the first magnetic member 211 and the second magnetic member 212 are rectangular, when both the first magnetic member 211 and the second magnetic member 212 are arc-shaped, the magnetic subassembly 21 can have a higher magnetic attraction.

[0068] Please see again Figure 8 In some embodiments, along the circumferential direction of the wireless charging module 10 , the length L of the magnetic subassembly 21 is in the range of 6 mm ≤ L ≤ 10 mm.

[0069] It is understood that the "circumferential direction" refers to a direction extending along the outer circumference of the wireless charging module 10. It is also understood that the circumferential direction is perpendicular to the radial direction of the wireless charging module 10. In a specific embodiment, the wireless charging module 10 is a circular structure, and the circumferential direction is the circumferential direction of the wireless charging module 10.

[0070] It can be understood that, along the circumferential direction of the magnetic assembly 20 , the length L of the magnetic subassembly 21 is in the range of 6 mm ≤ L ≤ 10 mm.

[0071] Optionally, along the circumferential direction of the wireless charging module 10 , the length of the first magnetic member 211 ranges from 6 mm to 10 mm.

[0072] Optionally, along the circumferential direction of the wireless charging module 10 , the length of the second magnetic member 212 ranges from 6 mm to 10 mm.

[0073] It should be noted that when the first magnetic member 211 and the second magnetic member 212 are both rectangular, the length L of the magnetic subassembly 21 along the circumferential direction of the wireless charging module 10 is uniform. When the first magnetic member 211 and the second magnetic member 212 are both arc-shaped, the length L of the magnetic subassembly 21 along the circumferential direction of the wireless charging module 10 is uneven, with the length of the magnetic subassembly 21 closer to the wireless charging module 10 being shorter and the length farther from the wireless charging module 10 being longer; that is, along the circumferential direction of the wireless charging module 10, the arc length of the surface of the magnetic subassembly 21 facing the wireless charging module 10 is shorter, and the arc length of the surface of the magnetic subassembly 21 facing away from the wireless charging module 10 is longer.

[0074] Specifically, along the circumferential direction of the wireless charging module 10, the length L of the magnetic subassembly 21 can be, but is not limited to, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc. If the length L of the magnetic subassembly 21 along the circumferential direction of the wireless charging module 10 is too small, the magnetic attraction of the magnetic assembly 20 is reduced, which is not conducive to the alignment between the coil of the wireless charging device 100 and the coil of the electronic device when the wireless charging device 100 is used to charge the electronic device; if the length L of the magnetic subassembly 21 along the circumferential direction of the wireless charging module 10 is too large, the magnetic field generated by the magnetic assembly 20 as a whole is large, which greatly interferes with the wireless charging module 10 and reduces the charging efficiency and charging speed of the wireless charging device 100.

[0075] In some embodiments, the distance d between two adjacent magnetic subassemblies 21 is in the range of 0.8 mm ≤ d ≤ 3 mm.

[0076] It should be noted that, because the multiple magnetic subassemblies 21 are arranged in a ring along the circumferential direction of the wireless charging module 10, the spacing between two adjacent magnetic subassemblies 21 varies at different locations. The distance between two adjacent magnetic subassemblies 21 close to one end of the wireless charging module 10 is smaller, and the distance between two adjacent magnetic subassemblies 21 away from the wireless charging module 10 is larger. In other words, the spacing between two adjacent magnetic subassemblies 21 gradually increases in the direction from the wireless charging module 10 to the magnetic subassemblies 21.

[0077] Specifically, the spacing d between two adjacent magnetic subassemblies 21 can be, but is not limited to, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, etc. If the spacing d between two adjacent magnetic subassemblies 21 is too small, the magnetic field generated by the magnetic assembly 20 as a whole is relatively large, which significantly interferes with the wireless charging module 10 and reduces the charging efficiency and speed of the wireless charging device 100. If the spacing d between two adjacent magnetic subassemblies 21 is too large, the magnetic attraction of the magnetic assembly 20 is too small, which is not conducive to the alignment between the coil of the wireless charging device 100 and the coil of the electronic device when the wireless charging device 100 is used to charge the electronic device.

[0078] Optionally, the distance d1 between two adjacent magnetic subassemblies 21 close to one end of the wireless charging module 10 ranges from 0.8 mm to 1.8 mm. Specifically, the distance between two adjacent magnetic subassemblies 21 close to one end of the wireless charging module 10 can be, but is not limited to, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, or 1.8 mm.

[0079] Optionally, the distance d2 between two adjacent magnetic subassemblies 21 and one end of the wireless charging module 10 ranges from 1.8 mm to 3 mm. Specifically, the distance between two adjacent magnetic subassemblies 21 and one end of the wireless charging module 10 is, but is not limited to, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, etc.

[0080] In some embodiments, along the radial direction of the wireless charging module 10 , the width w1 of the first magnetic member 211 is in the range of 2.0 mm ≤ w1 ≤ 3.5 mm.

[0081] Specifically, along the radial direction of the wireless charging module 10, the width w1 of the first magnetic part 211 can be but is not limited to 2.0mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc.

[0082] In this embodiment, if the width w1 of the first magnetic member 211 along the radial direction of the wireless charging module 10 is too small, the magnetic attraction of the magnetic subassembly 21 and the magnetic assembly 20 will be too small. When the wireless charging device 100 is used to charge the electronic device, it is not conducive to the alignment between the coil of the wireless charging device 100 and the coil of the electronic device. In addition, the width w1 of the first magnetic member 211 is too small, which makes the first magnetic member 211 fragile during assembly, increasing the difficulty of assembling the first magnetic member 211; if the width w1 of the first magnetic member 211 along the radial direction of the wireless charging module 10 is too large, the magnetic field generated by the magnetic assembly 20 will be too large, the interference to the wireless charging module 10 will be too large, and the charging efficiency and charging speed of the wireless charging device 100 will be reduced.

[0083] Optionally, along the radial direction of the wireless charging module 10 , a width w2 of the second magnetic member 212 is in the range of 2.0 mm ≤ w2 ≤ 3.5 mm.

[0084] Specifically, along the radial direction of the wireless charging module 10, the width w2 of the second magnetic part 212 can be but is not limited to 2.0mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc.

[0085] In this embodiment, if the width w2 of the second magnetic member 212 along the radial direction of the wireless charging module 10 is too small, the magnetic attraction of the magnetic subassembly 21 and the magnetic assembly 20 will be too small. When the wireless charging device 100 is used to charge the electronic device, it will be unfavorable for the alignment between the coil of the wireless charging device 100 and the coil of the electronic device. In addition, the width w2 of the second magnetic member 212 is too small, which makes the second magnetic member 212 fragile during assembly, increasing the difficulty of assembling the second magnetic member 212. If the width w2 of the second magnetic member 212 along the radial direction of the wireless charging module 10 is too large, the magnetic field generated by the magnetic assembly 20 will be too large, and the interference to the wireless charging module 10 will be too large, thereby reducing the charging efficiency and charging speed of the wireless charging device 100.

[0086] Figure 10 FIG. 2 is a schematic side structural diagram of a magnetic component 20 according to an embodiment of the present application.

[0087] See Figure 10 In some embodiments, the thickness h1 of the magnetic subassembly 21 in a direction perpendicular to the extension plane of the wireless charging module 10 is in the range of 1.0 mm ≤ h1 ≤ 1.7 mm.

[0088] It can be understood that, along the thickness direction of the wireless charging device 100 , the thickness h1 of the magnetic subassembly 21 is in the range of 1.0 mm ≤ h1 ≤ 1.7 mm.

[0089] Specifically, the thickness h1 of the magnetic subassembly 21 in a direction perpendicular to the extension plane of the wireless charging module 10 can be, but is not limited to, 1.0 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, etc.

[0090] Optionally, along the thickness direction of the wireless charging device 100 , the thickness of the first magnetic member 211 ranges from 1.0 mm to 1.7 mm.

[0092] Optionally, the thickness of the first magnetic member 211 and the second magnetic member 212 may be equal or different. In this embodiment, the thickness h1 of the magnetic subassembly 21 in the direction perpendicular to the extension plane of the wireless charging module 10 is too thin, and the first magnetic member 211 and the second magnetic member 212 are easily broken during assembly, which increases the difficulty of assembling the first magnetic member 211 and the second magnetic member 212; if the thickness h1 of the magnetic subassembly 21 in the direction perpendicular to the extension plane of the wireless charging module 10 is too thick, the magnetic field strength of the magnetic subassembly 21 increases, and the magnetic field strength of the magnetic assembly 20 is easily too large, which increases the interference of the magnetic field generated by the magnetic assembly 20 on the wireless charging device 100, reduces the charging efficiency and charging speed of the wireless charging device 100, and improves the user experience.

[0093] In one embodiment, the plurality of magnetic subassemblies 21 are arranged in a circular ring shape. The inner diameter of the circular ring structure formed by the plurality of magnetic subassemblies 21 arranged at intervals is 46 mm, and the outer diameter is 54 mm. Along the circumference of the wireless charging module 10, the length of the magnetic subassemblies 21 is 7.5 mm. The spacing between two adjacent magnetic subassemblies 21 near the end of the wireless charging module 10 is 1.06 mm, and the spacing between two adjacent magnetic subassemblies 21 away from the end of the wireless charging module 10 is 2.38 mm. Along the thickness direction of the wireless charging device 100, the thickness h1 of the magnetic subassemblies 21 is 1.5 mm. The circular ring structure formed by the plurality of magnetic subassemblies 21 has a notch, the notch is 9.6 mm in size, and the arc of the notch is 24°.

[0094] Please see again Figures 5 to 10In some embodiments, the magnetic component 20 further includes a magnetic member 22 , which is arranged around the periphery of the wireless charging module 10 and is used to adsorb and carry the multiple magnetic sub-components 21 , and the multiple magnetic sub-components 21 are spaced apart and arranged on the same side of the magnetic member 22 .

[0096] Optionally, along the thickness direction of the wireless charging module 10, the thickness h2 of the magnetic component 22 ranges from 0.5 mm to 0.9 mm; specifically, along the thickness direction of the wireless charging module 10, the thickness h2 of the magnetic component 22 can be but is not limited to 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, etc.

[0097] In this embodiment, by providing the magnetic attraction member 22 , the magnetic subassembly 21 can be adsorbed, thereby facilitating the assembly of the magnetic assembly 20 and better improving the assembly rate of the magnetic assembly 20 .

[0098] Figure 11 FIG. 1 is an assembly diagram of a heat sink 33 and an air flow driver 34 according to an embodiment of the present application.

The heat conductive sheet 31, the cooling sheet 32, and the heat sink 33 are sequentially stacked on one side of the wireless charging module 10. The wireless charging module 10, the heat conductive sheet 31, the cooling sheet 32, and the heat sink 33 are sequentially attached to each other. The heat conductive sheet 31 is arranged between the wireless charging module 10 and the cooling sheet 32. The heat sink 33 has a heat dissipation channel 331 connected to the outside. The air flow driver 34 is embedded in a side of the heat sink 33 away from the cooling sheet 32, and is used to drive gas to flow in the heat dissipation channel 331. The circuit board assembly 40 is arranged around the outer periphery of the cooling sheet 32 ​​and is located between the heat conductive sheet 31 and the heat sink 33. The circuit board assembly 40 is electrically connected to the wireless charging module 10, the cooling sheet 32, and the air flow driver 34, respectively.

[0100] Optionally, the circuit board assembly 40 has a first through hole 41 , and the cooling fin 32 is passed through the first through hole 41 .

[0101] It should be noted that the circuit board assembly 40 is used to control the cooling of the cooling plate 32 and to control the airflow driver 34 to open or close, thereby driving the gas to flow between the heat dissipation channel 331 and the external environment, thereby accelerating the heat dissipation speed of the wireless charging module 10.

[0102] Optionally, the heat conducting sheet 31 may be, but is not limited to, a metal sheet or alloy sheet; for example, it may be, but is not limited to, a copper sheet, an iron sheet, an aluminum alloy sheet, an aluminum sheet, etc. Heat conducting sheets 31 made of these materials have a higher heat conductivity rate and can quickly cool the wireless charging module 10, thereby ensuring the normal charging speed of the wireless charging device 100 and allowing the wireless charging device 100 to maintain a lower temperature while charging electronic devices.

[0103] Optionally, the magnetic member 22 is located between the heat conducting sheet 31 and the magnetic assembly 20 .

[0104] Optionally, the cooling fin 32 may be, but is not limited to, a semiconductor cooling fin (Thermoelectric Cooler, TEC for short).

[0105] Optionally, the airflow driver 34 may be, but is not limited to, a fan, blower, or other air blowing device. The airflow driver 34 is used to drive airflow into and between the heat sink 33 and the external environment, thereby removing heat from the heat sink 33 to dissipate heat from the heat sink 33.

[0106] Optionally, the heat sink 33 may be made of, but not limited to, at least one of aluminum, copper, and aluminum alloy.

[0107] When the wireless charging device 100 charges an electronic device (such as a mobile phone, tablet, etc.), a large amount of heat is generated. Due to the zero-matching design between the electronic device and the wireless charging device 100, the large amount of heat generated on the wireless charging device 100 cannot be dissipated quickly. Instead, the heat is transferred to the electronic device along the magnetic component 20 and the cover, causing the temperature of the electronic device and the wireless charging device 100 to be too high. The power drawn by the electronic device will decrease, and the charging speed of the wireless charging device 100 will decrease as the temperature rises, ultimately resulting in a poor user experience.

[0108] In this embodiment, the wireless charging device 100 includes a heat dissipation component 30, which includes a thermal conductive sheet 31, a cooling sheet 32, a heat sink 33 and an airflow driver 34. The thermal conductive sheet 31, the cooling sheet 32 ​​and the heat sink 33 are stacked in sequence on one side of the wireless charging module 10. The wireless charging module 10, the thermal conductive sheet 31, the cooling sheet 32 ​​and the heat sink 33 are arranged in sequence, and the thermal conductive sheet 31 is arranged between the wireless charging module 10 and the cooling sheet 32. In this way, when the wireless charging device 100 charges an electronic device, the heat generated by the wireless charging module 10 is transferred to the heat conducting sheet 31, and then evenly transferred to the cooling sheet 32 ​​through the heat conducting sheet 31. Then, through the cooperation of the heat dissipation element 33 and the air flow driver 34, the heat is transferred to the entire wireless charging device 100 and then to the outside of the wireless charging device 100, so that the wireless charging device 100 can be quickly cooled, which can effectively prevent the wireless charging device 100 and the electronic device from being overheated, and prevent the charging speed of the wireless charging device 100 from being reduced, which affects the user experience.

[0109] Figure 12 1 is a circuit block diagram of a wireless charging device 100 according to an embodiment of the present application.

The first processor 43 is electrically connected to the first memory 44, the wireless charging module 10, the cooling plate 32, the air flow driver 34 and the plug interface 45 respectively. The first processor 43 is used to control the wireless charging module 10 to charge, control the cooling plate 32 to cool, and control the air flow driver 34 to drive the gas to flow in the heat dissipation channel 331. The first memory 44 is used to store the program code required for the operation of the first processor 43. The plug interface 45 is used to electrically connect to an external power supply.

[0111] Optionally, the circuit board 42 has a first through hole 41 .

[0112] Optionally, the first processor 43 includes one or more general-purpose processors, where a general-purpose processor can be any type of device capable of processing electronic instructions, including a central processing unit (CPU), a microprocessor, a microcontroller, a main processor, a controller, and an ASIC.

[0113] Optionally, the first memory 44 may include volatile memory, such as random access memory (RAM); the first memory 44 may also include non-volatile memory (NVM), such as read-only memory (ROM), flash memory (FM), hard disk drive (HDD), or solid-state drive (SSD). The first memory 44 may also include a combination of the above-mentioned types of memory.

[0114] Optionally, the circuit board assembly 40 further includes an indicator light 46 , which is electrically connected to the first processor 43 , and is used to indicate a working state and an abnormal state of the wireless charging module 10 .

[0115] The working status includes, but is not limited to, a red light indicating that the battery is not fully charged, a green light indicating that the battery is fully charged, etc. The abnormal status includes, but is not limited to, a flashing red light indicating abnormal charging.

[0116] Please see again Figure 11 In some embodiments, the heat sink 33 includes a heat sink base 332 and a plurality of heat sink fins 333. The plurality of heat sink fins 333 are spaced apart on a side of the heat sink base 332 away from the refrigeration plate 32. The heat sink base 332 and the plurality of heat sink fins 333 enclose a plurality of heat dissipation channels 331 and an installation space 334 that are interconnected. The installation space 334 is used to set the airflow driver 34.

[0117] Optionally, the heat dissipation base plate 332 and the plurality of heat dissipation fins 333 are an integrated structure, and the heat dissipation base plate 332 and the plurality of heat dissipation fins 333 are different parts of the same component. The heat dissipation element 33 can be manufactured using an integrated molding process.

[0118] It is understandable that the plurality of heat dissipation fins 333 are spaced apart and arranged on the periphery of the air flow driver 34 . The air flow driver 34 is arranged near the middle position of the heat dissipation base plate 332 .

[0119] It can be understood that the heat dissipation channel 331 extends along the extension direction of the heat dissipation base plate 332 , which can accelerate the heat dissipation rate of the circuit board assembly 40 and the wireless charging module 10 .

[0120] In this embodiment, the heat sink 33 includes a heat sink base 332 and a plurality of heat sink fins 333. The heat sink base 332 and the plurality of heat sink fins 333 enclose a plurality of heat sink channels 331 and an installation space 334 that are interconnected. By providing a plurality of heat sink fins 333, the surface area of ​​the heat sink 33 is increased. The plurality of heat sink channels 331 can increase the gas circulation in the wireless charging device 100, thereby better dissipating the heat of the wireless charging module 10 and improving the heat dissipation efficiency.

[0121] In some embodiments, the heat dissipation fins 333 are arranged along a first direction (eg Figure 11 As shown by arrow X), a portion of the plurality of heat dissipation fins 333 extends along the second direction (as shown by arrow X). Figure 11 The plurality of heat dissipating fins 333 are spaced apart on one side of the airflow driver 34 as shown by arrow Y, and another portion of the plurality of heat dissipating fins 333 are spaced apart along a second direction on the other side of the airflow driver 34, wherein the first direction intersects with the second direction.

[0122] It is understandable that some of the multiple heat dissipation channels 331 are located on one side of the airflow driver 34, while others are located on the other side of the airflow driver 34. In this way, the airflow driven by the airflow driver 34 into the heat sink 33 can be ventilated from both sides of the heat sink 33, which can better improve the heat dissipation efficiency of the airflow driver 34.

[0123] It can be understood that the plurality of heat dissipation channels 331 extend along the first direction.

[0124] In one embodiment, the first direction is perpendicular to the second direction.

[0125] In this embodiment, by distributing the heat dissipation channels 331 of the heat sink 33 on opposite sides of the airflow driver 34, when the airflow driver 34 drives air into the heat dissipation channels 331, the heat sink 33 can discharge the air from both sides of the wireless charging device 100, thereby increasing the exhaust rate of the heat sink 33 and improving the heat dissipation effect. In addition, by controlling the spacing between the heat dissipation fins 333, the heat sink 33 can achieve a higher heat dissipation effect.

[0126] Figure 13 FIG. 1 is a bottom view of the wireless charging device 100 according to an embodiment of the present application. Figure 14 The wireless charging device 100 according to an embodiment of the present application is Figure 13 Cross-sectional view in the AA direction.

[0127] Please see again Figures 1 to 4 、 Figure 13 and Figure 14 In some embodiments, the wireless charging device 100 further includes a first shell 50 and a second shell 60. The first shell 50 and the second shell 60 enclose a first accommodating cavity 501. The first accommodating cavity 501 is used to accommodate the heat dissipation element 33, the circuit board assembly 40 and the cooling fin 32. The cooling fin 32 is also embedded in the second shell 60. The heat conducting sheet 31 is located on the side of the second shell 60 facing away from the first shell 50.

[0128] It can be understood that the second shell 60 is disposed around the outer periphery of the cooling fin 32. Optionally, the second shell 60 has a second through hole 61, and the cooling fin 32 is also disposed through the second through hole 61.

[0129] Optionally, a first air outlet 51 is provided on the first shell 50 at a position corresponding to the airflow driver 34 , and the first shell 50 is further provided with a second air outlet 52 connected to the heat dissipation channel 331 .

[0130] In some embodiments, when the airflow driver 34 is activated, air can enter through the first air vent 51, flow through the airflow driver 34 and the heat dissipation channel 331 in sequence, and then flow out of the wireless charging device 100 through the second air vent 52. In other embodiments, when the airflow driver 34 is activated, air can enter through the second air vent 52, flow through the heat dissipation channel 331 and the airflow driver 34 in sequence, and then flow out of the wireless charging device 100 through the first air vent 51.

[0131] In one embodiment, the first housing 50 includes a bottom (not shown) and side portions (not shown) that are connected by a bend. The side portions are arranged around the outer periphery of the bottom. The second housing 60 is engaged with the side portions of the first housing 50. The first air vent 51 is provided at the bottom of the first housing 50, and the second air vent 52 is provided at the side portions of the first housing 50.

[0132] Optionally, the number of first air vents 51 may be one or more. When there are multiple first air vents 51, the multiple first air vents 51 are spaced apart. The number of second air vents 52 may be one or more. When there are multiple second air vents 52, the multiple second air vents 52 are spaced apart. Optionally, the multiple second air vents 52 may correspond one-to-one with the multiple heat dissipation channels 331, with each second air vent 52 connecting to one heat dissipation channel 331, and different second air vents 52 connecting to different heat dissipation channels 331. It is understood that the multiple second air vents 52 are partially located on one side of the side of the first housing 50, while the other partially located on the other side of the side of the first housing 50.

[0133] Optionally, an orthographic projection of the airflow driver 34 at the bottom of the first housing 50 at least partially overlaps with the first air outlet 51 .

[0134] Optionally, through holes (not shown) are respectively provided in the first shell 50 and the second shell 60 at positions corresponding to the plug-in port 45 for the plug-in port 45 to pass through.

[0135] When the wireless charging device 100 is charging, the wireless charging module 10 generates heat. This heat is dispersed throughout the cooling fins 32 through the heat conducting sheet 31. The cooling fins 32 then transfer the heat to the heat sink 33. The airflow driver 34 is activated, and gas enters the airflow driver 34 from the first air outlet 51. The airflow driver 34 then sends the gas into the multiple heat dissipation channels 331, removing the heat from the heat sink 33. Finally, the gas is discharged from the wireless charging device 100 through the multiple second air outlets 52, thereby achieving rapid heat dissipation. This allows the heat generated by the wireless charging module 10 to be more quickly discharged from the wireless charging device 100 through the heat dissipation assembly 30, rapidly cooling the wireless charging device 100. This allows both the wireless charging device 100 and the electronic device to maintain lower temperatures when the wireless charging device 100 is charging, thereby improving the user experience of the wireless charging device 100.

[0136] In some embodiments, the wireless charging device 100 further includes a cover plate 70, which is located on the side of the wireless charging module 10 and the magnetic component 20 facing away from the thermal conductive sheet 31. The second shell 60 and the cover plate 70 enclose a second accommodating cavity 601, which is used to accommodate the thermal conductive sheet 31, the wireless charging module 10 and the magnetic component 20. The surface of the cover plate 70 facing away from the second shell 60 is a non-slip surface.

[0137] Optionally, the cover plate 70 may be, but is not limited to, thermally conductive silicone, so that when the wireless charging device 100 is charging, it can better dissipate heat for the wireless charging device 100 and can also effectively prevent the electronic device from sliding relative to the wireless charging device 100.

[0138] It is understandable that when the wireless charging device 100 is used to charge an electronic device, the cover plate 70 is in direct contact with the electronic device. It is understandable that the electronic device is carried on the cover plate 70 .

[0139] In this embodiment, by providing a cover plate 70, the cover plate 70 can be used to support the electronic device when the wireless charging device 100 is charging the electronic device. In addition, the cover plate 70 also has an anti-slip function, which can prevent the electronic device from sliding relative to the wireless charging device 100.

[0158] The magnetic assembly 20 of this embodiment includes a magnetic member 22 and a plurality of magnetic sub-assemblies 21. The magnetic member 22 is a circular ring with a notch. The size of the notch is 9.6 mm and the arc of the notch is 24°. The plurality of magnetic sub-assemblies 21 are arranged on the same side of the magnetic member 22 and are arranged at intervals around the circumference of the magnetic member 22. The inner diameter of the magnetic member 22 is 46 mm, the outer diameter is 54 mm, and the thickness of the magnetic member 22 is 0.7 mm. The circular ring structure formed by the plurality of magnetic sub-assemblies 21 is arranged at intervals. The inner diameter of the structure is 46 mm and the outer diameter is 54 mm. Along the circumferential direction of the wireless charging module 10, the length of the magnetic subassembly 21 is 7.5 mm. The distance between two adjacent magnetic subassemblies 21 close to the end of the wireless charging module 10 is 1.06 mm, and the distance between two adjacent magnetic subassemblies 21 away from the end of the wireless charging module 10 is 2.38 mm. Along the thickness direction of the wireless charging device 100, the thickness h1 of the magnetic subassembly 21 is 1.5 mm. The magnetic subassembly 21 is a rectangular parallelepiped.

[0159] The analog receiving end (RX) includes a circular iron sheet and a circular magnet. The notch size of the circular iron sheet is 9.6mm, the curvature of the notch is 24°, the inner diameter of the circular iron sheet is 46mm, the outer diameter is 54mm, and the thickness is 0.2mm; the notch size of the circular magnet is 9.6mm, the curvature of the notch is 24°, the inner diameter of the circular magnet is 46mm, the outer diameter is 54mm, and the thickness is 0.5mm.

[0160] Example 2

[0161] The difference between this embodiment and the first embodiment is that the magnetic subassembly 21 is an arc-shaped structure; and the thickness h1 of the magnetic subassembly 21 is 1.4 mm.

[0162] The magnetic assembly 20 of Example 1 and Example 2 is arranged opposite to the simulated receiving end (the magnetic assembly 20 and the annular magnet are arranged face to face), and the distance between the magnetic assembly 20 and the simulated receiving end is set to 1.4 mm, and the tension between the magnetic assembly 20 and the simulated receiving end is measured.

[0163] After multiple measurements, it was found that the average pulling force between the magnetic assembly 20 of Example 1 and the simulated receiving end was 10N, and the average pulling force between the magnetic assembly 20 of Example 2 and the simulated receiving end was 11N.

[0164] It can be seen from the tensile test results that, compared with the rectangular parallelepiped magnetic subassembly 21 in Example 1, the arc-shaped magnetic subassembly 21 in Example 2 can better improve the magnetic attraction of the magnetic assembly 20 .

[0165] Example 3

[0166] The wireless charging device 100 of the present embodiment has a charging power of 50W. When the wireless charging device 100 is turned on and charges a mobile phone at its rated power for 30 minutes at an ambient temperature of 25°C, the maximum temperature of the mobile phone screen is less than 39°C, the maximum temperature of the mobile phone case is less than 38°C, and the maximum temperature of the wireless charging device 100 is less than 42°C.

[0167] Example 4

[0168] The wireless charging device 100 of the present embodiment has a charging power of 50W. When the wireless charging device 100 is turned on and charges a mobile phone at its rated power for 30 minutes at an ambient temperature of 35°C, the maximum temperature of the mobile phone screen is less than 40°C, the maximum temperature of the mobile phone case is less than 39°C, and the maximum temperature of the wireless charging device 100 is less than 45°C.

[0169] The test results of Examples 3 and 4 show that the wireless charging device 100 of the present application can quickly dissipate the heat generated by the wireless charging module 10 during the charging process when charging the electronic device 300, thereby preventing the wireless charging device 100 and the electronic device 300 from overheating. This allows the wireless charging device 100 to maintain a high charging speed and a low charging temperature during charging, thereby improving the user experience.
