[0002] This application claims priority to Chinese Patent Application No. 202510482158.5, filed on April 16, 2025, entitled "An Electronic Device and an Electronic Device Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of wireless charging technology, and more particularly to an electronic device and electronic device components. Background Technology

[0004] Compared to wired charging, wireless charging has advantages such as portability and ease of operation. When an electronic device to be charged is brought close to a wireless charging device, the coil in the electronic device and the coil in the wireless charging device undergo electromagnetic induction. Energy (or electrical energy, or wireless charging signal) is transferred from the wireless charging device to the electronic device being charged, thus achieving wireless charging.

[0005] Currently, to meet users' demands for aesthetically pleasing electronic devices, all-metal electronic devices are gaining an increasingly larger market share. However, because metal has a shielding effect on electrical signals, the aforementioned solution of using coils to achieve wireless charging is no longer applicable. Summary of the Invention

[0006] This application provides an electronic device and an electronic device component that can ensure the wireless charging performance of the electronic device while satisfying the metallic appearance effect of the electronic device.

[0007] In a first aspect, this application provides an electronic device including a metal back cover assembly, a first electrode contact, a battery, and a charging circuit. The metal back cover assembly includes a metal back cover body and a camera decorative assembly, the camera decorative assembly being connected to the metal back cover body. The first electrode contact is connected to the battery via the charging circuit, and is disposed in at least one of the metal back cover body or the camera decorative assembly, with at least a portion of the first electrode contact exposed on the side of the metal back cover assembly facing away from the battery. The design of the electronic device provided in this application not only enables wireless charging of the electronic device using the first electrode contact, but also gives the electronic device a satisfactory metallic appearance.

[0008] In one possible implementation of this application, the electronic device further includes a flexible circuit board, through which the first electrode contact is connected to the charging circuit. This improves the ease of connection between the first electrode contact and the charging circuit, and also enhances the flexibility of the first electrode contact's configuration.

[0009] In one possible implementation of this application, the electronic device further includes a flexible circuit board, which in turn includes electrode terminals. A metal spring is located between the electrode terminals and the first electrode contact, and the metal spring elastically abuts against both the electrode terminals and the first electrode contact. This solution enables a stable electrical connection between the flexible circuit board and the first electrode contact.

[0010] In another possible implementation, the first electrode contact can be soldered to the flexible circuit board. This not only improves the ease of connection between the first electrode contact and the flexible circuit board, but also enhances the reliability of the connection, thereby ensuring a stable electrical connection between the first electrode contact and the flexible circuit board.

[0011] In one possible implementation of this application, the electronic device further includes a heat dissipation component located between the battery and the flexible circuit board, and in thermally conductive contact with both the battery and the flexible circuit board. This allows for heat dissipation from the battery and the flexible circuit board, thereby improving battery charging efficiency.

[0012] This application does not limit the specific configuration of the heat dissipation component. For example, in one possible implementation, the heat dissipation component may include at least one of a phase change material layer, a graphite sheet, or a vapor chamber. This ensures that the heat dissipation component can meet the heat dissipation requirements of the electronic device.

[0013] In one possible implementation of this application, the electronic device further includes a motherboard, on which the charging circuit is disposed. This allows the flexible circuit board to be connected to the motherboard, thereby enabling the connection between the flexible circuit board and the charging circuit, and thus connecting the first electrode contact to the charging circuit via the flexible circuit board.

[0014] In one possible implementation of this application, the metal back cover body includes a hollow area, a first electrode contact is embedded in the hollow area, and the first electrode contact is connected to the metal back cover body. This solution improves the ease of connection between the first electrode contact and the metal back cover body, and by designing the pattern of the hollow area, the setting of the first electrode contact and the appearance design of the metal back cover body can be integrated, thereby achieving wireless charging functionality while enhancing the aesthetics of the electronic device.

[0015] In one possible implementation of this application, the metal back cover body includes a camera mounting hole for mounting a camera. The camera decorative assembly includes a camera cover plate that covers the opening of the camera mounting hole. In this implementation, the first electrode contact can be disposed on the camera cover plate. Therefore, the wireless charging solution for electronic devices provided in this application offers high flexibility in the placement of the first electrode contact, thereby reducing the implementation difficulty of the solution.

[0016] Secondly, embodiments of this application also provide an electronic device assembly, including: a protective housing and the electronic device as described in the first aspect. The protective housing includes a casing, a charging coil, and a second electrode contact. The charging coil is housed within the casing, and the second electrode contact is connected to the charging coil and disposed within the casing. The casing is fitted onto the metal back cover assembly of the electronic device, and the second electrode contact abuts against the first electrode contact. In this electronic device assembly, the coil of the protective housing can be used to convert received electromagnetic waves into current, which can be transmitted to the first electrode contact via the second electrode contact, and then transmitted to the battery via the charging circuit of the electronic device to charge the battery of the electronic device. Furthermore, due to the design scheme of the electronic device assembly provided in this application, neither the first nor the second electrode contact is exposed, thus not only realizing the wireless charging function of the electronic device, but also improving the aesthetic appearance of the electronic device assembly.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.

[0025] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, the embodiments of this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the embodiments of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] To facilitate understanding of the technical solutions provided in the embodiments of this application, the application scenarios will be explained first below.

[0027] Figure 1 is a schematic diagram of the structure of an electronic device. As shown in Figure 1, the electronic device 100 may include a display screen 1 and a back cover 2. The display screen 1 and the back cover 2 are connected to form a receiving cavity between the display screen 1 and the back cover 2 for mounting electronic devices such as circuit boards, batteries, receivers, speakers, or cameras of the electronic device 100. The battery can power the electronic devices such as the display screen, circuit boards, receivers, speakers, and cameras.

[0028] Display screen 1 can be used to display information and provide an interactive interface for users. In various embodiments of this application, display screen 1 may be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0029] It is understandable that in order to ensure the realization of various functions of the electronic device 100, the battery needs to store enough power to supply the display screen 1 and the electronic components installed in the cavity between the display screen 1 and the back cover 2.

[0030] Currently, the batteries in electronic devices 100 are mostly rechargeable batteries, also known as rechargeable batteries, power batteries, or storage batteries. These are batteries that can be recharged after being discharged to reactivate the active materials and continue to be used. Therefore, when the battery of electronic device 100 is in a low-charge state, charging the battery can ensure the normal operation of electronic device 100.

[0031] The charging methods for the battery of electronic device 100 can be divided into wired charging and wireless charging. Compared with wired charging, wireless charging has advantages such as portability and ease of operation, and therefore its application in the charging field of electronic device 100 is becoming increasingly widespread. Referring to Figure 2, Figure 2 shows a wireless charging system composed of an electronic device and a wireless charging device provided by the prior art. In this wireless charging system, the wireless charging device 200 acts as a power supply device, and the electronic device 100 acts as a power receiving device. The wireless charging device 200 can be, for example, a wireless charger, and the electronic device 100 can be, for example, a wearable device such as a mobile phone, smartwatch, smart bracelet, or smart glasses, as well as a tablet computer.

[0032] In the embodiment shown in Figure 2, both the wireless charging device 200 and the electronic device 100 are equipped with coils. The coil in the wireless charging device 200 is a transmitting coil (not shown in Figure 2), and the coil in the electronic device 100 is a receiving coil 101. When current passes through the transmitting coil of the wireless charging device 200, an alternating magnetic field is generated, thereby converting electrical energy into electromagnetic waves. When the electronic device 100 is in contact with the wireless charging device 200, the receiving coil 101 of the electronic device 100 receives the electromagnetic waves converted by the wireless charging device 200, thus inducing a current in the receiving coil 101. Furthermore, since the receiving coil 101 can be connected to the charging circuit of the battery of the electronic device 100, the battery of the electronic device 100 can be charged.

[0033] As electronic devices 100 are designed towards miniaturization and thinness, their internal space is limited. Therefore, in the above embodiments, the receiving coil 101 is typically positioned between the battery and the back cover 2. However, to meet users' aesthetic requirements for the electronic devices 100, some electronic devices use metal for their back covers 2 to give them a metallic appearance. Since metal has a shielding effect on electromagnetic waves, the above-mentioned solution using the electromagnetic induction principle of a coil to achieve wireless charging is no longer applicable.

[0034] In view of this, this application provides a wireless charging solution for electronic devices including a metal back cover, so as to achieve wireless charging function while maintaining the metallic appearance of the electronic device. To facilitate understanding of the solution provided in this application, it will be described in detail below with reference to the accompanying drawings.

[0035] Figure 3 is a schematic diagram of an electronic device provided in an embodiment of this application. As shown in Figure 3, the electronic device 100 includes a metal back cover assembly 3, wherein the metal back cover assembly 3 includes a metal back cover body 31. This application does not limit the material of the metal back cover body 31, which can be exemplarily made of aluminum alloy or stainless steel, so that the electronic device 100 has a metallic appearance, thereby improving the aesthetics of the electronic device 100. In addition, in some embodiments of this application, the metal back cover body 31 can be a one-piece molded structure, that is, it can be processed from the same sheet metal, so that the electronic device 100 has an integrated metallic appearance.

[0036] Referring to Figure 4, which is an exploded view of the electronic device shown in Figure 3, and referring to Figures 3 and 4 together, it can be understood that in the electronic device 100 provided in this application, the display screen 1 can be connected to the metal back cover body 31 to form a receiving cavity between the display screen 1 and the metal back cover body 31. As shown in Figure 4, the electronic device 100 also includes a battery 4, wherein the battery 4 is located between the display screen 1 and the metal back cover body 31, that is, the battery 4 is accommodated in the receiving cavity between the display screen 1 and the metal back cover body 31.

[0037] Referring again to Figure 4, the electronic device 100 also includes a first electrode contact 5. In some embodiments of this application, the first electrode contact 5 is disposed on the metal back cover body 31, and at least a portion of the first electrode contact 5 is exposed from the side of the metal back cover assembly 3 away from the battery 4, that is, the first electrode contact 5 is visible from the outside of the electronic device 100. This allows the first electrode contact 5 to contact other electrodes outside the electronic device 100 and achieve electrical connection.

[0038] Furthermore, within the aforementioned receiving cavity of the electronic device 100, the first electrode contact 5 can be connected to the battery 4 via the charging circuit of the electronic device 100. This allows the charging circuit of the battery 4 of the electronic device 100 to be led out to the side of the metal back cover assembly 3 opposite to the display screen 1 via the first electrode contact 5. This enables the first electrode contact 5 to contact the electrodes of a power supply device located outside the electronic device 100, thereby allowing the power supply device to charge the battery 4 of the electronic device 100, thus realizing the wireless charging function of the electronic device 100.

[0039] It is understood that the first electrode contact 5 may be formed of a material with conductive properties. This application does not limit its specific shape, but it may be exemplarily a metal columnar structure, a metal sheet structure, or a metal protrusion.

[0040] Additionally, the electronic device 100 may include two first electrode contacts 5, which can be electrically connected to the corresponding electrodes of the charging circuit as positive and negative electrodes, respectively. In some embodiments of this application, each first electrode contact 5 may be a continuously arranged structure, or it may include multiple non-continuously arranged structures. Therefore, in this application, the specific arrangement of the first electrode contacts 5 is not limited, and it can be designed according to the installation space of the metal back cover body 31 and the appearance requirements of the electronic device 100.

[0041] Exemplary, in some embodiments of this application, referring to FIG5, which is another exploded view of the electronic device shown in FIG3, the metal back cover body 31 includes a hollow area 311, a first electrode contact 5 can be embedded in the hollow area 311, and the first electrode contact 5 is connected to the metal back cover body 31.

[0042] In some embodiments of this application, the periphery of the first electrode contact 5 and the metal back cover body 31 can be fixedly connected by adhesive dispensing. This effectively avoids contact between the first electrode contact 5 and the metal back cover body 31, thereby reducing the risk of short circuits at each of the first electrode contacts 5. It also ensures the waterproof performance of the connection between the first electrode contact 5 and the metal back cover body 31.

[0043] In some embodiments of this application, the hollow area 311 of the metal back cover body 31 can adopt a specific pattern design. For example, a hollow area with a specific logo pattern can be formed. This integrates the setting area of ​​the first electrode contact 5 with the marking area of ​​the metal back cover body 31, thereby realizing the wireless charging function of the electronic device 100 while reducing the design difficulty of the electronic device 100 and giving the electronic device 100 a more complete metallic appearance, thus improving the aesthetics of the electronic device 100.

[0044] Referring again to Figure 5, in this application, the electronic device 100 may further include a flexible circuit board 6, which is located between the battery 4 and the metal back cover body 31. The portion of the first electrode contact 5 facing the receiving cavity of the electronic device 100 can be connected to the flexible circuit board 6. In addition, the flexible circuit board 6 can also be connected to the charging circuit, thereby enabling the first electrode contact 5 to be connected to the charging circuit through the flexible circuit board 6. This effectively improves the convenience of connecting the first electrode contact 5 to the charging circuit.

[0045] In some embodiments of this application, the flexible circuit board 6 may include electrode terminals (not shown in FIG. 5), and the electronic device 100 may further include a metal spring (not shown in FIG. 5), which is located between the electrode terminals of the flexible circuit board 6 and the corresponding first electrode contacts 5, and the metal spring elastically abuts against the electrode terminals and the first electrode contacts 5. This allows the electrode terminals and the corresponding first electrode contacts 5 to be electrically connected via the metal spring.

[0046] In other embodiments of this application, the flexible circuit board 6 can be soldered to the first electrode contact 5, for example, the electrode terminals of the flexible circuit board 6 are soldered to the corresponding first electrode contact 5. This makes the connection between the electrode terminals of the flexible circuit board 6 and the corresponding first electrode contact 5 simpler and ensures the reliability of the connection between the flexible circuit board and the first electrode contact 5.

[0047] The above embodiments are merely illustrative examples of possible connection methods between the flexible circuit board 6 and the first electrode contact 5. Based on this, other possible methods can also be used to achieve electrical connection between the flexible circuit board 6 and the first electrode contact 5, which will not be listed here, but should all be understood to fall within the protection scope of this application.

[0048] In some embodiments of this application, the electronic device 100 may further include a motherboard (not shown in FIG. 5), which may be disposed between the display screen 1 and the metal back cover body 31, and the aforementioned charging circuit may be disposed on the motherboard. Since the first electrode contact 5 can be connected to the charging circuit through the flexible circuit board 6 in this application, it is beneficial to improve the freedom of the setting position of the first electrode contact 5.

[0049] In some embodiments of this application, the flexible circuit board 6 and the main board can be connected via a board-to-board (BTB) connector, thereby connecting the flexible circuit board 6 to the charging circuit. In other possible embodiments of this application, the flexible circuit board 6 and the main board can also be connected via soldering or other possible methods to achieve the connection between the flexible circuit board 6 and the charging circuit.

[0050] Understandably, during the charging process of electronic device 100, current flows through the first electrode contact 5 and the flexible circuit board 6 to the charging circuit, and then to the battery 4. This process generates a significant amount of heat. To ensure the charging efficiency of electronic device 100, as shown in Figure 5, electronic device 100 also includes a heat dissipation component 7. This heat dissipation component 7 is located between the battery 4 and the flexible circuit board 6, and is in thermally conductive contact with both the battery 4 and the flexible circuit board 6 to facilitate heat exchange and thus dissipate heat from the battery 4 and the flexible circuit board 6.

[0051] This application does not limit the specific configuration of the heat dissipation component 7. For example, in some embodiments of this application, the heat dissipation component 7 may include at least one of a phase change material layer, a graphite sheet, or a vapor chamber (VC). That is, the heat dissipation component 7 may include only one heat dissipation layer or multiple heat dissipation layers. In addition, when the heat dissipation component 7 includes multiple heat dissipation layers, the multiple heat dissipation layers may be the same type of heat dissipation layer or a combination of different types of heat dissipation layers, and the multiple heat dissipation layers may be stacked to improve the heat dissipation capacity of the heat dissipation component 7.

[0052] In this application, the number of heat dissipation components 7 in the electronic device 100 can be selected according to specific heat dissipation requirements. For example, in some embodiments of this application, the electronic device 100 includes two heat dissipation components 7. For ease of description, the two heat dissipation components 7 can be referred to as the first heat dissipation component and the second heat dissipation component, respectively. The first heat dissipation component can be the heat dissipation component located between the flexible circuit board 6 and the battery 4 as described above. The second heat dissipation component is located between the motherboard and other components such as the camera, and the second heat dissipation component is in thermally conductive contact with the motherboard and the camera to exchange heat with them, thereby achieving heat dissipation for the motherboard and the camera.

[0053] The above embodiments are merely illustrative examples of possible heat dissipation solutions for the electronic device 100 provided in this application. In other embodiments of this application, the electronic device 100 may also employ other possible methods to achieve heat dissipation, which will not be listed here, but should all be understood to fall within the protection scope of this application.

[0054] In the above embodiments, the design principle of the wireless charging scheme of the electronic device 100 provided in this application is explained by taking the first electrode contact 5 being disposed on the metal back cover body 31 as an example. In other embodiments of this application, the specific placement position of the first electrode contact 5 can be adaptively adjusted while meeting the design requirements.

[0055] Referring to Figure 5, in the electronic device provided in this application, the metal back cover assembly 3 also includes a camera decoration assembly 32, which is connected to the metal back cover body 31 to protect and decorate the camera of the electronic device 100.

[0056] It is understood that, in order to connect the camera decorative component 32 to the metal back cover body 31, in one possible embodiment of this application, the metal back cover body 31 includes a camera mounting hole for mounting a camera to enable the camera function of the electronic device 100.

[0057] In some embodiments of this application, the camera cover can be connected to the opening of the camera mounting hole by means of adhesive bonding, so as to achieve a fixed connection between the camera cover and the metal back cover body 31 while ensuring the sealing of the opening of the camera mounting hole, thereby improving the waterproof performance of the electronic device 100.

[0058] This application does not limit the material of the camera cover. Exemplary examples include a glass cover, a plastic cover, or a cover made of fiber composite materials, so as to protect the camera while ensuring that the camera cover can meet the camera's light transmittance requirements.

[0059] In some embodiments of this application, the camera decorative assembly 32 may further include a circumferentially arranged metal ring structure surrounding the camera cover to enhance the metallic appearance of the electronic device. Furthermore, the metal ring structure can be coupled to the floor of the electronic device 100 to ground the camera decorative assembly 32. In other embodiments of this application, the camera decorative assembly 32 may be grounded in other ways, such as through metal springs or conductive foam coupled to the metal structure of the camera decorative assembly 32 and the floor.

[0060] The foregoing only provides an illustrative demonstration and description of a portion of the structure of the camera decorative component 32. In addition, the camera decorative component 32 can be adapted to the specific design requirements of the electronic device 100 by adjusting the specific configuration of some structures, or by adding or removing some structural elements. These modifications are not listed here, but all should be understood as falling within the scope of protection of this application.

[0061] As described above, the wireless charging solution provided in this application allows for flexible placement of the first electrode contact 5. Therefore, in some embodiments of this application, the first electrode contact 5 can also be placed on the camera decorative component 32. For example, the camera decorative component 32 may include a camera cover plate, which can cover the opening of the camera mounting hole to serve as an external component of the camera decorative component 32, thereby protecting the camera. In some embodiments of this application, the first electrode contact 5 can be placed on the camera cover plate. The specific placement method of the first electrode contact 5 and its placement on the camera cover plate can refer to any of the above embodiments. For example, the camera cover plate may include a hollow area, and the first electrode contact 5 is embedded in the hollow area, etc., which will not be elaborated here.

[0062] It is worth mentioning that when the first electrode contact 5 is set on the camera cover, the setting area of ​​the first electrode contact 5 should be staggered with the light-incident area of ​​the camera to ensure the imaging effect of the camera.

[0063] Since there can be two first electrode contacts 5, in some possible embodiments of this application, one first electrode contact 5 can be disposed on the metal back cover body 31, and the other first electrode contact 5 can be disposed on the camera decorative component 32. Alternatively, a portion of one first electrode contact 5 can be disposed on the metal back cover body 31, and another portion can be disposed on the camera decorative component 32.

[0064] In the electronic device provided in this application, the specific location of the first electrode contact 5 is not limited to this. For example, it can also be located in other parts of the metal back cover assembly 3, which will not be listed here.

[0065] As can be seen from the above introduction, the wireless charging solution provided in this application can not only realize the wireless charging function of electronic device 100, but also give electronic device 100 a metal appearance that meets the requirements, thereby enhancing the market competitiveness of electronic device 100.

[0066] It is understood that, using the design scheme provided in this application, the first electrode contact 5 can contact the corresponding electrode contact of an external power supply device to achieve charging of the electronic device. In view of this, this application also provides an electronic device assembly.

[0067] Referring to Figure 6, which is an exploded view of an electronic device assembly provided in an embodiment of this application, Figure 6 illustrates the relative positions of the various parts of the electronic device assembly. The electronic device assembly includes a protective housing 300 and the electronic device 100 described in any of the embodiments above. The protective housing 300 has a wireless charging function. Specifically, the protective housing 300 includes a housing 301 and a charging coil 302, wherein the charging coil 302 is housed within the housing 301. In other words, the protective housing 300 can utilize the principle of electromagnetic induction to transfer electrical energy.

[0068] Referring to Figure 6, the protective shell 300 also includes a second electrode contact 303, which is connected to the charging coil 302. The current converted by the charging coil 302 can flow to the second electrode contact 303.

[0069] Furthermore, the second electrode contact 303 can be disposed on the housing 301, and the housing 301 of the protective shell 300 can be fitted onto the metal rear cover assembly 3 of the electronic device 100, so that the second electrode contact 303 abuts against the first electrode contact 5. Thus, the electronic device 100 can be protected by the protective shell 300, and the electronic device 100 can also be charged by the protective shell 300.

[0070] In some embodiments of this application, when the electronic device 100 needs to be charged, the protective shell 300 of the electronic device component can be brought into contact with a power supply device equipped with a transmitting coil. Then, the charging coil 302 of the protective shell 300 can act as a receiving coil to receive electromagnetic waves converted by the power supply device, so as to generate an induced current in the charging coil 302 of the protective shell 300. This induced current can be transmitted to the first electrode contact 5 through the second electrode contact 303, and then transmitted to the battery 4 through the charging circuit of the electronic device 100 to achieve charging of the battery 4.

[0071] It is worth mentioning that this application does not limit the specific arrangement of the second electrode contact 303. For example, in the embodiment shown in FIG6, the second electrode contact 303 may be a conductive protrusion disposed on the housing 301. This can help improve the contact reliability between the second electrode contact 303 and the first electrode contact 5.

[0072] In addition, the second electrode contact 303 can also be set to a specific pattern shape, such as a specific logo pattern shape, to achieve the integrated design of the second electrode contact 303 and the logo of the protective case 300, so as to improve the integration of the protective case 300 and realize the wireless charging function of the protective case 300.

[0073] In the above embodiments of this application, the wireless charging function of the electronic device 100 is described using the electronic device 100 as a power receiving device as an example. In some scenarios, the electronic device 100 can also act as a power supply device to power other devices. For example, in some embodiments of this application, the electronic device 100 can power a protective case with decorative lights to illuminate the lights for a decorative effect. In some embodiments of this application, the electronic device 100 can also power a protective case with a liquid cooling system to dissipate heat from the electronic device 100 using the liquid cooling system. In some embodiments of this application, the electronic device 100 can also power a keyboard to enable keyboard input. Alternatively, in some embodiments of this application, the electronic device 100 can also charge smart glasses or smart bracelets.

[0074] It is understood that when the electronic device 100 provided in this application is used as a power supply device, it can still make contact with the corresponding electrode contact of the powered device through the first electrode contact 5, so as to enable the electronic device 100 to supply power to the hand flashlight.

[0075] In the above embodiments, the wireless charging solution provided in this application is described using a mobile phone as an example of electronic device 100. This wireless charging solution can also be applied to other electronic devices with wireless charging capabilities, such as tablets, laptops, smartwatches, or Bluetooth headsets. Regardless of the type of electronic device, the implementation of wireless charging is similar, and will not be elaborated upon here.

[0076] It is worth mentioning that, in the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions between different embodiments are consistent and can be referenced by each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0077] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of the embodiments of this application. Therefore, if these modifications and variations to the embodiments of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
