It is easy to understand that one side surface of the first adhesive layer 6 is bonded to the magnet assembly 4 and the wireless charging coil 5, and the other side surface of the first adhesive layer 6 is bonded to the second diaphragm 7. Further, the magnet assembly 4 is disposed around the shielding heat sink 3. That is to say, the shielding heat sink 3 is located in the central area of ​​the substrate 2, while the magnet assembly 4 is arranged in the edge area of ​​the substrate 2, and the wireless charging coil 5 is located in the area surrounded by the magnet assembly 4. Furthermore, the magnet assembly 4 includes a plurality of first magnets 41 and at least one second magnet 42, and the thickness of the second magnet 42 is less than that of the first magnet 41. That is to say, the first magnets 41 and the second magnets 42 of different thicknesses are arranged and distributed along the edge of the substrate 2. Thus, by making the thickness of the second magnet 42 less than that of the first magnet 41, a groove 44 is formed at the position of the second magnet 42, so that some parts of the product can be accommodated in the groove 44. Based on this, the wireless charging module can be installed at a predetermined position of the product through the wireless charging module installation structure, wherein the first magnets 41 and the second magnets 42 of different thicknesses can provide more design space for the product while ensuring the magnetic attraction performance of the product, which helps to reduce the thickness of the product. It should be noted that the product includes wireless chargers and electronic devices with wireless charging functions such as mobile phones, tablet computers, and smart watches.

[0045] Combination Figure 2 and Figure 4 As shown, in one embodiment, the wireless charging module further includes a second adhesive layer 8, that is, the wireless charging module mounting structure further includes a second adhesive layer 8. Further, the second adhesive layer 8 is disposed at the edge of the substrate 2, and is used to bond the magnet assembly 4 to the substrate 2. It is easy to understand that the two side surfaces of the second adhesive layer 8 are respectively bonded to the edge of the substrate 2 and the magnet assembly 4, so as to realize that the magnet assembly 4 is disposed at the edge position of the substrate 2.

[0046] Combination Figure 2 and Figure 4As shown, in one embodiment, the wireless charging module further includes a third adhesive layer 9, that is, the wireless charging module mounting structure further includes a third adhesive layer 9. Further, the third adhesive layer 9 is disposed on the shielding heat sink 3, and is used to bond the wireless charging coil 5 to the shielding heat sink 3. It is easy to understand that the two side surfaces of the third adhesive layer 9 are respectively bonded to the shielding heat sink 3 and the wireless charging coil 5, so as to realize that the wireless charging coil 5 is disposed on the shielding heat sink 3.

[0047] In one embodiment, the second magnet 42 is bonded to the first adhesive layer 6. That is, when the first adhesive layer 6 is bonded to the magnet assembly 4, the groove 44 formed at the position of the second magnet 42 is located on the side away from the first adhesive layer 6, so that when the wireless charging module is bonded to a predetermined position of the product through the first adhesive layer 6, the groove 44 formed at the position of the second magnet 42 can be exposed in a direction away from the first adhesive layer 6, so as to accommodate other components at the corresponding position of the product.

[0048] Combination Figure 2 and Figure 4 As shown, in one embodiment, a first notch 43 is formed on the magnet assembly 4. That is, the first magnet 41 and the second magnet 42 are arranged and distributed to reserve the first notch 43. Correspondingly, a second notch 21 is provided on the substrate 2, and a third notch 61 is provided on the first adhesive layer 6. Further, the second notch 21 and the third notch 61 are aligned with the first notch 43. That is, the third notch 61, the first notch 43 and the second notch 21 are connected from top to bottom. Thus, when the wireless charging module is bonded to the predetermined position of the product through the first adhesive layer 6, the avoidance structure formed by the third notch 61, the first notch 43 and the second notch 21 can reserve some space for other parts at the corresponding position of the product. Exemplarily, the connection end of the wireless charging coil 5 is arranged at the position of the third notch 61, the first notch 43 and the second notch 21, so that when the wireless charging module is bonded to the product through the first adhesive layer 6, it is electrically connected to other parts of the product at this position. In addition, by providing the first notch 43, the second notch 21 and the third notch 61, it is helpful to position and assemble the magnet assembly 4, the substrate 2 and the first adhesive layer 6.

[0049] like Figure 4As shown, in one embodiment, a fourth notch 11 is provided on the first diaphragm 1, and a fifth notch 71 is provided on the second diaphragm 7. Furthermore, the fourth notch 11 and the fifth notch 71 are aligned with the first notch 43. Thus, when the wireless charging module is installed through the wireless charging module installation structure, the fifth notch 71, the third notch 61, the first notch 43, the second notch 21 and the fourth notch 11 are connected vertically, so that when the wireless charging module is installed, the first diaphragm 1 and the second diaphragm 7 can avoid some parts of the product. In addition, by providing the fourth notch 11 and the fifth notch 71, it is helpful to position the substrate 2, the magnet assembly 4 and the first adhesive layer 6 between the first diaphragm 1 and the second diaphragm 7, that is, it is helpful to position the wireless charging module between the first diaphragm 1 and the second diaphragm 7, so that the positioning and installation of the wireless charging module can be easily achieved.

[0050] Figure 5 is a schematic diagram of the structure of a magnet assembly provided by an embodiment of the present invention, such as Figure 5 As shown, in one embodiment, the magnet assembly 4 includes a plurality of first magnets 41 and a second magnet 42. Furthermore, the second magnet 42 is located at a position opposite to the first notch 43. That is to say, corresponding to the overall circular shape of the substrate 2, the magnet assembly 4 is composed of a plurality of first magnets 41 and a second magnet 42 to form an annular structure, and the second magnet 42 and the first notch 43 are located at both ends of the diameter. Therefore, through the separation of the second magnet 42 and the first notch 43, the plurality of first magnets 41 are distributed in an axisymmetric manner, which helps to avoid affecting the performance of the product.

[0051] Figure 6 is a schematic diagram of the structure of another magnet assembly provided by an embodiment of the present invention, such as Figure 6 As shown, in one embodiment, the magnet assembly 4 includes a plurality of first magnets 41 and a plurality of second magnets 42. Further, the plurality of second magnets 42 are centrally symmetrically distributed. Exemplarily, the four second magnets 42 are cross-shapedly distributed. Furthermore, the plurality of first magnets 41 and the plurality of second magnets 42 are axially symmetrically distributed relative to the diameter of the position of the first notch 43. Thus, the symmetrical structure of the magnet assembly 4 helps to avoid affecting the performance of the product.

[0052] It should be noted that, as an optional implementation, the magnet assembly 4 may also be composed of a first magnet 41 and a plurality of second magnets 42 arranged in an arranged manner so as to adapt to different product structures.

[0053] Combination Figure 2 and Figure 4As shown, in one embodiment, a sixth notch 22 is provided on the substrate 2. It is easy to understand that the sixth notch 22 is aligned with the second magnet 42. Therefore, when the wireless charging module is bonded to the product through the first adhesive layer 6, the parts of the product can extend into the groove 44 formed by the magnet assembly 4 at the position of the second magnet 42 through the sixth notch 22. In addition, by providing the sixth notch 22, it is helpful to position and assemble the magnet assembly 4 and the substrate 2.

[0054] It should be noted that if Figure 4 As shown, in one embodiment, the second adhesive layer 8 is composed of two symmetrical arc-shaped strip structures, and is formed with a seventh notch 81 and an eighth notch 82. The seventh notch 81 is aligned with the first notch 43, and the eighth notch 82 is aligned with the second magnet 42. Thus, by setting the second adhesive layer 8 matching the magnet assembly 4, the magnet assembly 4 can be accurately positioned and set on the substrate 2.

[0055] In one embodiment, the thickness of the first magnet 41 is equal to the sum of the thicknesses of the shielding heat sink 3 and the wireless charging coil 5. Therefore, when the shielding heat sink 3 and the wireless charging coil 5 are sequentially arranged on the substrate 2, and the first magnet 41 is arranged on the substrate, the upper surface of the first magnet 41 is flush with the upper surface of the wireless charging coil 5, so that the first adhesive layer 6 arranged on the magnet assembly 4 and the wireless charging coil 5 can maintain a planar state, so as to arrange the second diaphragm 7 on the first adhesive layer 6, and facilitate the wireless charging module to be bonded to the product through the first adhesive layer 6.

[0056] In one embodiment, the shielding heat sink 3 includes a graphite layer and a ferrite layer. It is easy to understand that the graphite layer is used to provide heat conduction and heat dissipation function for the wireless charging coil 5, thereby ensuring the wireless charging quality of the wireless charging module. Correspondingly, the ferrite layer is used to provide a shielding function for the wireless charging coil 5, thereby improving the wireless charging efficiency of the wireless charging module. It should be noted that the shielding heat sink 3 can also be made of other materials. As an optional embodiment, the shielding heat sink 3 includes a graphite layer, a copper foil layer and a nanocrystalline layer stacked in sequence to achieve a shielding and heat dissipation function for the wireless charging coil 5.

[0057] In one embodiment, the substrate 2 is made of polyethylene terephthalate (PET), which can be used for a long time in a wide temperature range, and has excellent electrical insulation and dimensional stability, which helps to improve the service life of the wireless charging module and the products installed with the wireless charging module. It should be noted that the substrate 2 can also be made of other materials. As an optional embodiment, the substrate 2 is made of polyimide (PI), which is resistant to high temperatures and has high insulation performance, and has excellent comprehensive performance, which helps to improve the service life of the wireless charging module and the products installed with the wireless charging module.

[0058] In one embodiment, the first adhesive layer 6 is made of pressure-sensitive adhesive (PSA). Optionally, the second adhesive layer 8 and the third adhesive layer 9 are also made of pressure-sensitive adhesive. After the wireless charging module mounting structure is assembled, the pressure can be maintained to ensure that the parts bonded by the first adhesive layer 6, the second adhesive layer 8 and the third adhesive layer 9 can be effectively fixed. It should be noted that, in one embodiment, the second diaphragm 7 is a release film so that the second diaphragm 7 can be peeled off when the wireless charging module is installed. After the second diaphragm 7 is peeled off, the wireless charging module can be bonded to the product through the first adhesive layer 6.

[0059] like Figure 4 As shown, in one embodiment, the edge of the first diaphragm 1 extends outward to form a first positioning portion 12. Correspondingly, the edge of the second diaphragm 7 extends outward to form a second positioning portion 72, and the second positioning portion 72 is aligned with the first positioning portion 12. Thus, the first diaphragm 1 can be positioned by the first positioning portion 12, and the second diaphragm 7 can be positioned by the second positioning portion 72, so as to position and set the various components of the wireless charging module. In addition, when the wireless charging module is installed using the wireless charging module mounting structure, the first diaphragm 1 can be peeled off by the first positioning portion 12, and the second diaphragm can be peeled off by the second positioning portion 72.

[0060] like Figure 4 As shown, in one embodiment, the first positioning portion 12 is provided with a first positioning hole 121. Correspondingly, the second positioning portion 72 is provided with a second positioning hole 721, and the second positioning hole 721 is aligned with the first positioning hole 121. Therefore, by providing the first positioning hole 121 and the second positioning hole 721, the positioning reference function of the first diaphragm 1 and the second diaphragm 7 can be further improved.

[0061] like Figure 2 and Figure 4 As shown, in one embodiment, at least one gasket 13 is provided on the first diaphragm. It should be noted that the number and position of the gaskets 13 match the second magnet 42, so that the second magnet 42 can be set on the gasket 13 through the eighth notch 82 and the sixth notch 22. Thus, by setting the gasket 13, the height difference in the magnet assembly 4 during the assembly process can be compensated, so that the second magnet 42 can be bonded to the first adhesive layer 6. Optionally, the surface of the gasket 13 is sticky, so that the second magnet 42 can be adhered to ensure that the wireless charging module installation structure does not cause the second magnet 42 to shift during the turnover process. It should be noted that the gasket 13 is made of polyethylene terephthalate (PET), has excellent physical and mechanical properties and dimensional stability, and can further prevent the position of the second magnet 42 from shifting.

[0062] like Figure 2 and Figure 4As shown, in one embodiment, a plurality of pre-break wires 14 are provided on the first diaphragm 1. Further, a pre-break wire 14 is provided on both sides of each gasket 13. It should be noted that the pre-break wire 14 can enhance the pressure-maintaining effect of the magnet assembly 4.

[0063] The embodiment of the present invention further provides an electronic device, which includes the wireless charging module as described above. It should be noted that the electronic device can have more design space while ensuring the magnetic attraction performance through the first magnet 41 and the second magnet 42 of different thicknesses in the wireless charging module, which helps to achieve the lightness and thinness of the electronic device.

[0070] S60, disposing a first adhesive layer on the magnet assembly and the wireless charging coil.

[0071] S70, disposing the second film on the first adhesive layer.

[0072] Therefore, the assembly method of the wireless charging module installation structure not only completes the assembly of the wireless charging module, but also realizes the assembly of the wireless charging module between the first diaphragm and the second diaphragm, that is, the assembly of the wireless charging module installation structure is realized, which is helpful for the subsequent movement and installation of the wireless charging module to the predetermined position of the product. In addition, by setting the first magnet and the second magnet of different thicknesses, more design space can be provided for the product while ensuring the magnetic attraction performance of the product.

[0075] S200, adhering the upper surface of the first adhesive layer to a predetermined position of the product.

[0076] S300, peeling off the first film.

[0077] Therefore, through the method of using the wireless charging module mounting structure, the wireless charging module can be installed on the product through the assembled wireless charging module mounting structure. It is easy to understand that by setting the first magnet and the second magnet of different thicknesses, more design space can be provided for the product while ensuring the magnetic attraction performance of the product.
