Description

Technical Field

[0001] The present application relates to the field of terminal devices, and in particular, to a wireless charging component and a wireless charging method. Background Art

[0002] In wireless charging scenarios, metal near the charging coil or power transmission coil may generate heat due to eddy current effects. This heat generation can reduce the energy conversion efficiency of the power transmission coil, and consequently, the efficiency of wireless charging. Furthermore, if the heat generated during charging cannot be dissipated promptly, the accumulated heat may degrade the performance of the device's electronic components, affecting user experience and posing safety risks.

[0003] How to improve the efficiency of wireless charging and reduce the heat generated during wireless charging is an issue worth considering. Summary of the Invention

[0004] The present application provides a wireless charging component, which includes two charging coils arranged relative to each other and capable of forming a connected loop. A magnetic isolation sheet with functions such as magnetic conduction, magnetic resistance, and magnetic loss reduction is provided between the charging coils. In different charging scenarios, the connected loop between the charging coils can be disconnected or connected. In conjunction with the use of the magnetic isolation sheet, the wireless charging component has higher charging efficiency in different charging scenarios, and the coils generate less heat during the charging process.

[0005] In a first aspect, a wireless charging component is provided, which includes a first coil, a second coil and a first magnetic isolation plate. The first coil and the second coil are arranged opposite to each other and spaced apart. The first coil and the second coil are electrically connected to form a connecting loop; the first magnetic isolation plate is located between the first coil and the second coil.

[0006] In one possible implementation, the first coil and the second coil are both annular or nearly annular structures, and the first magnetic shielding sheet may be a sheet-like structure. The projections of the first coil and the second coil on the plane of the first magnetic shielding sheet may fall within the range of the first magnetic shielding sheet. For example, the distance between the edges of the projections of the first coil and the second coil on the plane of the first magnetic shielding sheet and the edge of the first magnetic shielding sheet is greater than or equal to a first distance threshold.

[0007] In a possible implementation, a communication loop is formed between the first coil and the second coil, and energy received by the first coil can be transmitted to the second coil through the communication loop. The second coil can send the energy from the first coil to other coils.

[0008] In a possible implementation, the communication loop between the first coil and the second coil is disconnected, and the energy received by the first coil or the second coil is converted into electrical energy for use by a power consumption unit or an energy storage unit in the wireless charging component.

[0009] In a possible implementation, the thickness of the first magnetic isolation sheet is greater than or equal to a first thickness threshold.

[0010] In a possible implementation, the first coil and the second coil are respectively adhered to two opposite surfaces of the first magnetic isolation sheet.

[0011] The magnetic barrier between the first and second coils reduces the impact of magnetic flux from one side on the coil on the other side. This reduces heat generation in the coil on the other side, improving the energy conversion efficiency of the power transmission device. This technical solution helps reduce heat generation in wireless charging coils in various charging scenarios and improves the charging efficiency of the power transmission device.

[0012] In combination with the first aspect, in some implementations of the first aspect, the circuit assembly further includes a first control unit, the first control unit, the first coil, and the second coil are interconnected to form a first loop, and the first control unit is used to control the connection or disconnection of the first loop.

[0013] A control unit is provided on the connection loop between the first coil and the second coil, and the connection or disconnection of the connection lines of the two coils is controlled by switching different states of the control unit. The implementation of this technical solution is conducive to improving the reliability of the control of the circuit working state of the wireless charging component, reducing the heat generated by the wireless charging component during the charging process, improving the energy conversion efficiency of the power transmission equipment, and to a certain extent, improving the safety of the wireless charging component during the charging process and reducing the probability of failure of the wireless charging component.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the circuit assembly further includes a second control unit and an energy storage unit, the second control unit, the second coil and the energy storage unit are interconnected to form a second loop, and the second control unit is used to control the connection or disconnection of the second loop.

[0015] In some scenarios, the energy storage unit may be a battery.

[0016] In some scenarios, when the second circuit is connected, the second coil can convert the received magnetic energy into electrical energy, but when the second circuit is disconnected, the second coil cannot convert the received magnetic energy into electrical energy. In other words, when the second circuit is connected, the receiving end of the wireless charging component can receive energy, but when the second circuit is disconnected, the receiving end of the wireless charging component cannot receive energy.

[0017] A control unit is provided on the second circuit, and controls whether the second coil stores energy in the energy storage unit by switching the control unit on or off. The wireless charging component is provided with a second circuit including an energy storage unit. In some scenarios, the magnetic energy received by the wireless charging component can be converted into electrical energy through the second circuit and stored in the energy storage unit. Based on the second circuit, the wireless charging component can be configured with a variety of electrical components to realize the various functions of the wireless charging component.

[0018] In combination with the first aspect, in certain implementations of the first aspect, when the first circuit is connected, the second control unit is used to control the second circuit to be disconnected; when the first circuit is disconnected, the second control unit is used to control the second circuit to be connected.

[0019] In a possible implementation, the first circuit is disconnected and the second circuit is connected, or the first circuit is connected and the second circuit is disconnected, or both the first circuit and the second circuit are disconnected.

[0020] In some scenarios, the above solution can also be understood as the first loop and the second loop are not in a connected state at the same time.

[0021] In combination with the first aspect, in some implementations of the first aspect, the circuit assembly further includes a second magnetic isolation plate, and the second magnetic isolation plate is located between the first coil and the first magnetic isolation plate.

[0022] In some scenarios, the above solution can also be understood as: the second magnetic isolation plate is arranged close to the second coil, and the first magnetic isolation plate is arranged close to the first coil.

[0023] By providing two magnetic isolation plates, each positioned close to the first coil and the second coil, the plates can better converge the magnetic flux lines of the adjacent coils, minimizing the impact of the magnetic field on one side of the plates on the coil on the other side. This technical solution helps improve the overall heat generation of the wireless charging assembly in different charging scenarios, reduces the impact of the wireless charging assembly on the charging efficiency of the power transmission device in different charging scenarios, and improves the energy conversion efficiency of the power transmission device.

[0024] In combination with the first aspect, in some implementations of the first aspect, the wireless charging assembly further includes a heat dissipation structure, and the heat dissipation structure is in contact with the first magnetic isolation sheet.

[0025] In a possible implementation, the heat dissipation structure may be a heat dissipation structure made of a material such as graphite or a temperature homogenizer, which has good thermal conductivity and has little or substantially no effect on the magnetic field.

[0026] The heat generated by the coil can be transferred to the heat dissipation structure through the magnetic shield. The heat dissipation structure has excellent thermal conductivity, allowing it to quickly dissipate the heat generated during wireless charging. The implementation of this technical solution helps reduce the probability of localized overheating in the wireless charging assembly, which can affect the performance of functional components within the wireless charging assembly.

[0027] In combination with the first aspect, in some implementations of the first aspect, the first magnetic isolation sheet is adhered to the side of the first coil close to the second coil through a first thermally conductive material, and the second magnetic isolation sheet is adhered to the side of the second coil close to the first coil through a second thermally conductive material.

[0028] In a possible implementation, the thermal conductivity of the first heat-conducting material and the thermal conductivity of the second heat-conducting material are both greater than the second threshold.

[0029] In a possible implementation, the first heat-conducting material or the second heat-conducting material is heat-conducting silicone grease and / or heat-conducting resin.

[0030] By bonding the magnetic isolation sheet and the coil with an adhesive material having a good thermal conductivity, the heat generated by the coil can be well conducted to the magnetic isolation sheet through the adhesive material and then dissipated. This technical solution is beneficial to reducing the probability of heat accumulation in the first coil or the second coil and the local temperature of the wireless charging component being too high, and is beneficial to improving the safety of the wireless charging component during the charging process.

In the embodiment of the present application, the Android system with a layered architecture is used as an example to illustrate the software structure of the electronic device 100.

[0090] It is understood that the interface connection relationship between the modules illustrated in the embodiments of the present application is merely an illustrative illustration and does not constitute a structural limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may also adopt different interface connection methods from the above embodiments, or a combination of multiple interface connection methods.

[0091] Figure 2This is a block diagram of the software structure of the electronic device 100 according to an embodiment of the present application. The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers: the application (app) layer, the application framework layer, the Android runtime and system libraries, and the kernel layer. The application layer may include a series of application packages.

[0092] like Figure 2 As shown, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0093] The application framework layer provides an application programming interface (API) and programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0094] like Figure 2 As shown, the application framework layer may include a window manager, an activity manager, a package manager, a resource manager, a view system, a phone manager, a notification manager, and the like.

[0095] Resource Manager, also known as Resource Management Service (RMS), provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0096] A window manager, also known as a window management service (WMS), manages windowed programs. It can determine the display size, determine whether a status bar is present, lock the screen, and take screenshots.

[0097] The activity manager, also known as the activity manager service (AMS), manages all application processes in the system.

[0098] The package manager, also known as the package management service (PMS), is responsible for functions such as application installation and uninstallation, component query and matching, and permission management.

[0099] The view system includes visual controls, such as those for displaying text and images. The view system is used to build applications. A display interface can consist of one or more views. For example, a display interface containing a text notification icon might include a view for displaying text and a view for displaying images.

[0100] The Notification Manager allows applications to display notifications in the status bar. These messages can be displayed briefly and then disappear automatically without user interaction. For example, the Notification Manager is used to notify users of completed downloads and message reminders. The Notification Manager can also display notifications in the top status bar of the system as icons or scrolling text, such as notifications from background applications, or as dialog windows on the screen. Examples include text messages in the status bar, beeps, vibrations on electronic devices, and flashing indicator lights.

[0101] The system library can include multiple functional modules, such as a surface manager, media libraries, a 3D graphics processing library (such as OpenGL ES), and a 2D graphics engine (such as SGL).

[0102] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0103] The media library supports playback and recording of a variety of common audio and video formats, as well as static image files. The media library can support a variety of audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0104] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0105] A 2D graphics engine is a drawing engine for 2D drawings.

[0106] The kernel layer is the layer between hardware and software. The kernel layer includes at least display driver, camera driver, audio driver, and sensor driver.

[0107] Before formally introducing the embodiments of the present application, the terms that may be used in the following content are first explained.

[0108] Nanocrystalline materials refer to crystalline materials with nanometer-sized grains or nanoparticles with crystal structures.

[0109] Electromagnetic induction refers to the phenomenon that when the magnetic flux passing through any closed loop changes, an induced electromotive force is generated in the loop, and when the loop is a conductor loop, an induced current is generated.

[0110] Eddy current effect: When a bulk metal conductor is placed in a changing magnetic field or moves in a magnetic field to cut through magnetic lines of force, a vortex-shaped induced current will be generated in the conductor.

[0111] Magnetic permeability is the ratio of the magnetic induction intensity B inside a material to the magnetic field intensity H.

[0112] The magnetic loss factor is a physical quantity that describes the energy loss of a material in an alternating magnetic field. It represents the ratio of energy loss to stored energy during each magnetization or demagnetization process. A larger magnetic loss factor indicates greater energy loss in the material in an alternating magnetic field. A higher magnetic loss factor may also cause increased heating of the device.

[0113] Figure 3 This is a schematic diagram of a wireless charging scenario provided in an embodiment of the present application, involving a charging base 10, a first component 20 and an electronic device 30. The first component 20 is located between the charging base 10 and the electronic device 30, and the charging base 10 and the electronic device 30 are respectively arranged near two opposite sides of the first component 20.

[0114] In one scenario, the charging base 10 can wirelessly charge the electronic device 30 based on principles such as electromagnetic induction or magnetic resonance, and the electronic device 30 can also wirelessly charge the first component 20 based on principles such as electromagnetic induction or magnetic resonance. In some scenarios, the charging base 10 can also wirelessly charge the first component 20 based on principles such as electromagnetic induction or magnetic resonance.

[0115] Combine Figure 4 In some instances, the charging base 10 can be electrically connected to a power supply circuit and can include a coil 11 therein. The coil 11 can be used to convert electrical energy provided by the power supply circuit into magnetic energy. In some scenarios, the charging base 10 can also be referred to as a wireless charging stand, an electromagnetic charger, a wireless charging stand, or a wireless charging pad. In other words, the charging base 10 can have various device forms, which are not limited in this application.

[0116] The electronic device 30 may be an electronic device that supports a wireless charging function, for example, a portable electronic device such as a mobile phone and a tablet computer that supports a wireless charging function. For another example, a wearable device such as a watch, a bracelet, an augmented reality (AR) glasses or a virtual reality (VR) glasses that supports a wireless charging function. The electronic device 30 may be provided with a coil 31, a first power unit and a first energy storage unit. The coil 31 may be used to receive magnetic energy emitted by the coil 11 of the charging base 10, and convert the received magnetic energy into electrical energy that can be stored in the first energy storage unit or can be used by the first power unit. The coil 31 may also convert the electrical energy stored in the first energy storage unit into magnetic energy. For the description of the software architecture and hardware architecture of the electronic device 30, reference may be made to the relevant content of the electronic device 100 in the previous text, which will not be repeated here.

[0117] In some scenarios, the first component 20 can be regarded as an accessory of the electronic device 30 and used in conjunction with the electronic device 30. For example, the electronic device 30 can be a mobile phone, and the first component 20 can be a protective case for the mobile phone. Also for example, the electronic device 30 can be AR glasses, and the first component 20 can be a glasses case for storing or accommodating the AR glasses or an accessory for use with AR glasses, such as a handle for use with AR glasses. A coil 21, a second power unit, and a second energy storage unit can be provided in the first component 20. The coil 21 can be used to receive magnetic energy emitted by the coil 31 of the electronic device 30, and convert the received magnetic energy into electrical energy that can be stored in the second energy storage unit or can be used by the second power unit.

[0118] like Figure 4 As shown, the coil 11 in the charging base 10, the coil 21 in the first component 20, and the coil 31 in the electronic device 30 can be arranged relative to each other to improve the efficiency of wireless charging of the electronic device 30 by the charging base 10, and to improve the efficiency of wireless charging of the first component 20 by the electronic device 30. In one possible implementation, the three coils can be prismatic, cylindrical, or approximately prismatic or approximately cylindrical structures. In some scenarios, the relative arrangement of the three coils can be understood as the three coils being coaxial.

[0119] When the coil 11 of the charging base 10 is wirelessly charging the electronic device 30, although the coil 21 of the first component 20 is close to the coil 11 that can emit magnetic energy, the coil 21 does not convert the magnetic energy of the coil 11 into electrical energy. Instead, it converts a certain amount of magnetic energy into internal energy, that is, generates heat. This not only reduces the energy conversion efficiency of the charging base 10, but also causes a certain amount of heat generated by the coil 21 of the first component 20 to accumulate around the electronic device 30 during charging, creating a safety hazard.

[0120] In order to improve the efficiency of wireless charging of the electronic device 30 by the charging base 10 and reduce the heat generated by the first component 20 during the process, the present application provides a second component 40. When the second component 40 is used in conjunction with the electronic device 30 instead of the first component 20, the second component 40 generates less heat during the wireless charging of the electronic device 30 by the charging base 10, and the charging efficiency of the charging base 10 is improved.

[0121] In the charging scenario, the relative position relationship between the second component 40, the charging base 10 and the electronic device 30 can be the same as Figure 3 The relative positional relationship between the first component 20, the charging base 10 and the electronic device 30 is consistent. That is, the second component 40 is located between the charging base 10 and the electronic device 30, and the charging base 10 and the electronic device 30 are respectively arranged near the two opposite sides of the second component 40.

[0122] In some scenarios, the second component 40 can be considered an accessory of the electronic device 30 and used in conjunction with the electronic device 30. For example, the electronic device 30 can be a mobile phone, and the second component 40 can be a protective case for the mobile phone. Similarly, for example, the electronic device 30 can be an AR pair of glasses, and the second component 40 can be a glasses case for storing or accommodating the AR glasses, or an accessory used in conjunction with the AR glasses, such as a handle for use with the AR glasses.

[0123] The second component 40 may include a substrate, a cover, and a circuit component 200. The substrate and the cover are stacked in the thickness direction, and the circuit component 200 may be sandwiched between the substrate and the cover. In this case, the second component 40 may also be referred to as a housing 40.

[0124] In some examples, the second component 40 may further include a thermally conductive structure or a heat dissipation structure. The thermally conductive structure may be made of graphite or a heat spreader. For example, the thermally conductive structure may be composed of a material with good thermal conductivity and minimal impact on the magnetic field. The thermally conductive structure may be disposed between the substrate and cover of the second component 40 and may contact the heat-generating components in the circuit assembly 200, thereby dissipating heat generated by the second component 40 and preventing localized overheating. In some examples, the thermally conductive structure may be disposed on the side of the magnetic shielding sheet described below that faces away from the coil.

[0125] like Figure 5As shown, the circuit component 200 may include a coil 202 and a coil 204, and the second component 40 may include a magnetic isolation sheet 206. The coil 202 and the coil 204 are spaced apart along a first direction, and the magnetic isolation sheet 206 may be disposed between the coil 202 and the coil 204. The first direction is the plane where the coil 202 is located or the normal direction of the plane where the coil 204 is located. In other words, the coil 202, the magnetic isolation sheet 206, and the coil 204 are sequentially disposed along the normal direction of the plane where the coil 202 is located. When the second component 40 is used in conjunction with the electronic device 30, the coil 204 may be close to the coil 31 of the electronic device 30, and the coil 202 may be away from the coil 31 of the electronic device 30.

[0126] As an example but not limitation, coil 202 and coil 204 can both be annular (such as a circular ring or a square ring) or a nearly annular structure, the magnetic isolation plate 206 can be a circular plate or a square plate, and coil 202, coil 204 and magnetic isolation plate 206 can be coaxially arranged.

[0127] In some examples, coil 202 may be electrically connected to coil 204 , or in other words, coil 202 and coil 204 may be connected to each other to form a loop.

[0128] For example, the circuit assembly 200 may include a first connecting wire and a second connecting wire, both of which are used to connect the coil 202 and the coil 204. For example, the coil 202 may include a first end and a second end, and the coil 204 may include a third end and a fourth end. The first connecting wire may be used to connect the first end of the coil 202 and the third end of the coil 204, and the second connecting wire may be used to connect the second end of the coil 202 and the fourth end of the coil 204.

[0129] When charging base 10 is wirelessly charging electronic device 30, coil 202 of second component 40 is close to charging base 10, and coil 204 of second component 40 is close to electronic device 30. Coil 202 can receive magnetic energy from coil 11 of charging base 10 and transmit the received magnetic energy to coil 204 connected thereto via an electrical connection line. Coil 204 can then transmit the received magnetic energy to coil 31 of electronic device 30.

[0130] Because coil 202 and coil 204 are electrically connected via a connecting line, the magnetic energy generated by coil 11 of charging base 10 is transmitted efficiently between coil 202 and coil 204 with minimal loss. This can, to a certain extent, improve the efficiency of wireless charging of electronic device 30 by charging base 10.

[0131] The magnetic isolation sheet 206 disposed between the coil 202 and the coil 204 can, to a certain extent, direct the magnetic field lines generated by the transmitting coil around the coil 202 or the coil 204 , thereby reducing the probability of the other coil heating to a certain extent and improving the energy conversion rate of wireless charging.

[0132] In some examples, the magnetic spacer 206 may be made of a material having a magnetic loss factor less than or equal to a first threshold.

[0133] For example, the magnetic isolation sheet 206 may be composed of one or more of the following materials: nanocrystalline material, soft ferrite, silicon steel sheet, amorphous soft magnetic material, soft magnetic composite material, or metal alloy with high magnetic permeability. Soft ferrites may include manganese-zinc ferrite and nickel-zinc ferrite, etc. Amorphous soft magnetic materials may include iron-based amorphous alloys and nano-amorphous alloys, etc. High magnetic permeability metal alloys may include molybdenum-nickel alloys and iron-nickel alloys, etc.

[0134] In some examples, the area of the magnetic isolation sheet 206 is larger than the areas of the coils 202 and 204. In other words, the projections of the coils 202 and 204 on the plane where the magnetic isolation sheet 206 is located can be located within the range of the magnetic isolation sheet 206. For example, the distance between the edges of the projections of the coils 202 and 204 on the plane where the magnetic isolation sheet 206 is located and the edge of the magnetic isolation sheet 206 is greater than or equal to a first distance threshold.

[0135] The area of the magnetic isolation sheet 206 is set to be larger than the areas of the coil 202 and the coil 204. The magnetic isolation sheet 206 can better block the magnetic lines of force and better play the role of gathering the magnetic lines of force.

[0136] In some examples, the magnetic isolation sheet 206 includes a first surface and a second surface disposed opposite to each other. The first surface of the magnetic isolation sheet 206 can be attached to the coil 202 , and the second surface of the magnetic isolation sheet 206 can be attached to the second coil 204 .

[0137] For example, an adhesive material may be provided between the first surface of the magnetic isolation sheet 206 and the coil 202, and the adhesive material may be used to bond the first surface of the magnetic isolation sheet 206 to the coil 202. Similarly, the aforementioned adhesive material may be provided between the second surface of the magnetic isolation sheet 206 and the coil 204, and the adhesive material may be used to bond the second surface of the magnetic isolation sheet 206 to the coil 204.

[0138] In some examples, the thermal conductivity of the adhesive material may be greater than the second threshold. For example, the adhesive material may be thermal grease and / or thermal resin, such as silicone thermal adhesive, epoxy thermal adhesive, and acrylic thermal adhesive.

[0139] By bonding the magnetic isolation sheet and the coil with an adhesive material having a good thermal conductivity, the heat generated by the coil can be better transferred to the magnetic isolation sheet through the adhesive material and then dissipated. This technical solution is beneficial to reducing the probability of heat accumulation in the coil 202 or the coil 204 and the local temperature increase of the second component 40.

[0140] For example, when the charging base 10 is wirelessly charging the electronic device 30, or in other words, when the coil 11 of the charging base 10 generates a magnetic field whose strength and / or direction are constantly changing, the magnetic isolation sheet 206 located on the side of the coil 202 facing away from the coil 11 can gather the magnetic lines of force on the side of the magnetic isolation sheet 206 facing the coil 202, more effectively converting the magnetic energy generated by the coil 11 into electrical energy, and thus achieving higher wireless charging efficiency for the charging base 10. Fewer magnetic lines of force are distributed near the coil 204, so the coil 204 is less affected by the magnetic field generated by the coil 11, the coil 204 generates less heat, and the probability of the electronic components in the charging base 10, the electronic device 30, and the second component 40 experiencing performance degradation due to excessive temperature is reduced.

[0141] For example, in a scenario where the electronic device 30 is wirelessly charging the second component 200, or in other words, when the coil 31 of the electronic device 30 generates a magnetic field whose strength and / or direction are constantly changing, the magnetic isolation sheet 206 located on the side of the coil 204 facing away from the coil 31 can gather the magnetic lines of force on the side of the magnetic isolation sheet 206 facing the coil 204, more effectively converting the magnetic energy generated by the coil 31 into electrical energy, and achieving higher wireless charging efficiency for the electronic device 30. Fewer magnetic lines of force are distributed near the coil 202, so the coil 202 is less affected by the magnetic field generated by the coil 31, the coil 202 generates less heat, and the probability of the electronic components in the charging base 10, the electronic device 30, and the second component 40 experiencing performance degradation due to excessive temperature is reduced.

[0142] In some examples, such as Figure 6 As shown, the second component 40 may include a magnetic isolation sheet 206 and a magnetic isolation sheet 214 . The magnetic isolation sheet 214 is consistent with the magnetic isolation sheet 206 and is disposed between the coil 202 and the coil 204 .

[0143] For example, the magnetic isolation sheet 206 can be disposed near the coil 202, for example, the magnetic isolation sheet 206 can be attached to the side of the coil 202 near the coil 204. The magnetic isolation sheet 214 can be disposed near the coil 204, for example, the magnetic isolation sheet 214 can be attached to the side of the coil 204 near the coil 202.

[0144] By setting two magnetic isolation plates close to the coil 202 and the coil 204 respectively, the second component 40 has less impact on the wireless charging efficiency of the charging base 10 and the wireless charging efficiency of the electronic device 30, and less heat is generated in different charging scenarios.

[0145] Similarly, the magnetic isolation sheet 206 can be adhered to the coil 202 by an adhesive material having excellent thermal conductivity, and the magnetic isolation sheet 214 can be adhered to the coil 204 by an adhesive material having excellent thermal conductivity. Similarly, the thermal conductivity of the adhesive material can be greater than or equal to the second threshold, and the adhesive material can be thermal grease and / or thermally conductive resin, such as silicone thermal adhesive, epoxy thermal adhesive, and acrylic thermal adhesive.

[0146] The magnetic isolation sheet and the coil are connected by an adhesive material with good thermal conductivity. The heat generated during the operation of the coil can be conducted through the thermally conductive adhesive material and the magnetic isolation sheet, which is beneficial to reducing the probability of heat accumulation near the charging coil during wireless charging.

[0147] Continue to refer Figure 6 In some examples, the second component 40 may further include a heat-conducting structure 216, which may be disposed between the magnetic isolation sheet 214 and the magnetic isolation sheet 206. The heat-conducting structure 216 may be in contact with the magnetic isolation sheet 206 and the magnetic isolation sheet 214 of the circuit component 200, respectively. The heat generated by the coil 202 may be transferred to the heat-conducting structure 216 via the magnetic isolation sheet 206 and then dissipated. The heat generated by the coil 204 may be transferred to the heat-conducting structure 216 via the magnetic isolation sheet 214 and then dissipated. The implementation of this technical solution is conducive to improving the heat dissipation efficiency of the second component 40 and reducing the probability of excessive local temperature in the second component 40.

[0148] Figure 7 and Figure 8 A circuit diagram of a circuit assembly 200 is provided as an example. In some examples, the circuit assembly 200 may further include a first control unit 212. The first control unit 212 may be disposed in a loop formed by the connection of the coil 202 and the coil 204. For example, this loop may be referred to as a first loop. The first control unit 212 may be configured to control the connection or disconnection of the connection line between the coil 202 and the coil 204. In other words, the first control unit 212 may be configured to control the connection or disconnection of the first loop.

[0149] For example, the first control unit 212 can default to a connected state or a closed state. In other words, the second component 40 can default to the charging base 10 as an energy transfer device in the wireless charging scenario of the electronic device 30. When the first control unit 212 is adjusted to the off state, the second component 40 can switch from an energy transfer device to a charged device or a charging device.

[0150] In a possible implementation, the first control unit 212 may have a function of a single-pole double-throw switch, and the first control unit 212 may adjust an on or off state by receiving a control signal.

[0151] Exemplarily, the aforementioned first connecting line for connecting coil 202 and coil 204 may include a first sub-connecting line and a second sub-connecting line, the control unit 212 may include an input end and an output end, one end of the first sub-connecting line can be connected to the first end of the coil 202, the other end of the first sub-connecting line can be connected to the input end of the control unit 212, one end of the second sub-connecting line can be connected to the output end of the control unit 212, and the other end of the second sub-connecting line can be connected to the third end of the coil 204.

[0152] In some examples, during the process of wireless charging of the electronic device 30 by the charging base 10, as shown in FIG. Figure 7 As shown, the first control unit 212 can control the connection line (i.e., the first loop) between the coil 202 and the coil 204 to be connected. In this way, the magnetic energy received by the coil 202 from the coil 11 can be transmitted to the coil 204 through the connection line. This can reduce the loss during the energy transmission process to a certain extent and improve the charging efficiency of the charging base 10 for wireless charging of the electronic device 30.

[0153] In some examples, the circuit assembly 200 may further include an energy storage unit 210, which may be electrically connected to the coil 204. In other words, the energy storage unit 210 may form a closed loop with the coil 204. When the coil 31 of the electronic device 30 converts the electrical energy in the energy storage unit 33 into magnetic energy and transmits it toward the second assembly 40, the coil 204 in the second assembly 40 may receive the magnetic energy and convert it into electrical energy for storage in the energy storage unit 210. This process may be considered as the process of the electronic device 30 wirelessly charging the second assembly 40.

[0154] Exemplarily, the energy storage unit 210 may be a battery, such as a lithium battery.

[0155] In some examples, the circuit assembly 200 may further include a power consumption unit 208 . The power consumption unit 208 may be connected to the aforementioned energy storage unit 210 to form a loop. The energy storage unit 210 may serve as a battery for the power consumption unit.

[0156] Exemplarily, the power consumption unit 208 may be one or more of the following: a lighting device, a heat dissipation device, an environmental sensor, a Hall sensor, or a proximity sensor, etc., which is not limited in this application.

[0157] In some examples, the circuit assembly 200 may further include a second control unit 218, which may be provided on a loop formed by the energy storage unit 210 and the coil 204, for example, referred to as a second loop. The second control unit 218 may be configured to control the connection or disconnection of the second loop.

[0158] In the process of the electronic device 30 wirelessly charging the second component 40, as shown in FIG. Figure 8 As shown, the first control unit 212 can control the connection line (i.e., the first loop) between the coil 202 and the coil 204 to be disconnected. The second control unit 218 can control the connection line (i.e., the second loop) between the coil 204 and the power unit 208 and the energy storage unit 210 to be connected. In this way, the magnetic energy received by the coil 204 from the coil 31 will not be transmitted to the coil 202, but will be converted into electrical energy and stored in the energy storage unit 210. This is beneficial to improve the charging efficiency of the electronic device 30 for the second component 40 wirelessly.

[0159] For example, the second control unit 218 may be in an off state by default. In other words, the electronic device 30 will not wirelessly charge the second component 40 by default.

[0160] In a possible implementation, the second control unit 218 may have a function of a single-pole double-throw switch, and the second control unit 218 may adjust the on or off state by receiving a control signal.

[0161] In one possible implementation, the second control unit 218 may be a control chip of the wireless charging receiving end of the second component 40, which may be used to control the turning on or off of the charging function of the wireless charging receiving end of the second component 40. For example, when the aforementioned second circuit is connected, the charging function of the wireless charging receiving end of the second component 40 is turned on, and when the second circuit is disconnected, the charging function of the wireless charging receiving end of the second component 40 is turned off.

[0162] In some examples, a processing unit may also be provided in the second component 40 , which sends a control signal to the aforementioned first control unit 212 and / or second control unit 218 to implement control of the first control unit 212 and the second control unit 218 .

[0163] In some examples, continue to refer to Figure 7 or Figure 8 The circuit assembly 200 may further include a third control unit 220. The third control unit 220 may form a loop with the energy storage unit 210, the power unit 208, and the first control unit 212, for example, referred to as a third loop. The third control unit 220 may be used to control the power unit 208 in the second assembly 40 to be turned on or off.

[0164] In a possible implementation, the third control unit 220 may have a function of a single-pole double-throw switch, and the third control unit 220 may adjust the on or off state by receiving a control signal.

[0165] For example, the third control unit 220 may be in a connected state or a closed state by default.

[0166] refer to Figure 7 When the charging base 10 is wirelessly charging the electronic device 30, the first control unit 212 and the third control unit 220 are both connected, the second control unit 218 is disconnected, and the first and third loops in the aforementioned circuit assembly 200 are closed. On the one hand, the coil 202 transfers energy to the coil 204 via the first loop, and then transmits it to the electronic device 30, achieving wireless charging of the electronic device 30; on the other hand, the energy storage unit 210 can power the power unit 208 to achieve functions such as lighting or heat dissipation of the second component 40. In some examples, in response to the user shutting down the third control unit 220, the third loop can be disconnected, and the power unit 208 of the second component 40 can stop operating.

[0167] refer to Figure 8 When the electronic device 30 is charging the second component 40, the second control unit 218 and the third control unit 220 are both connected, the first control unit 212 is disconnected, and the second loop in the circuit assembly 200 is closed. The coil 204 can replenish power for the energy storage unit 210. Because the energy storage unit 210 is in a charging state, in some examples, the third loop can be configured to be disconnected, that is, the power unit 208 of the second component 40 is disabled.

[0168] Figure 9 The figure shows a charging method based on the above-mentioned circuit component 200 provided in an embodiment of the present application. In different charging scenarios, the electronic device 30 can send different control information to the second component 40 to control the connection or disconnection of the connection line between the coil 202 and the coil 204 in the second component 40, thereby improving the wireless charging efficiency of the charging base 10 or the electronic device 30.

[0169] S101, the electronic device 30 obtains target information.

[0170] The electronic device 30 may enable the wireless charging function by default, and correspondingly disable the wireless reverse charging function by default.

[0171] In some scenarios, the above-mentioned wireless reverse charging function can also be called reverse wireless charging function, wireless power sharing function, etc., which means using the electric energy stored in the electronic device 30 to wirelessly charge other electronic devices. This application does not limit the name of this function.

[0172] In some examples, the target information may include first information, the first information being used to instruct the user to enable the wireless reverse charging function of the electronic device 30. Alternatively, the first information is used to instruct the user to disable the wireless reverse charging function of the electronic device 30. In other words, if the wireless reverse charging function of the electronic device 30 is disabled, the first information may be used to instruct the user to enable the wireless reverse charging function of the electronic device 30; if the wireless reverse charging function of the electronic device 30 is enabled, the first information may be used to instruct the user to disable the wireless reverse charging function of the electronic device 30.

[0173] Figure 10 The diagram of the user interface 300 of the electronic device 30 is shown. For example, the user interface 300 may display a "wireless reverse charging" switch control 301. The user can turn on or off the wireless reverse charging function of the electronic device by operating the switch control 301. The first information can be used to instruct the user to click the "wireless reverse charging" switch control 301.

[0174] In a default state, or in other words, when the wireless reverse charging function of the electronic device 30 is turned off, in response to the user's operation of the "wireless reverse charging" switch control 301, the electronic device 30 can turn on the wireless reverse charging function.

[0175] When the wireless reverse charging function of the electronic device 30 is turned on, in response to the user's operation on the “wireless reverse charging” switch control 301 , the electronic device 30 may turn off the wireless reverse charging function.

[0176] In some examples, the target information may include second information, which may be used to indicate that the remaining power of the electronic device 30 is less than or equal to the first power threshold. Alternatively, the second information may be used to indicate that the remaining power of the electronic device 30 is greater than the first power threshold and the remaining power of the second component 40 is less than or equal to the second power threshold.

[0177] Exemplarily, when the wireless reverse charging function of the electronic device 30 is turned on, in response to the remaining power of the electronic device 30 being less than or equal to the first power threshold, the electronic device 30 turns off the wireless reverse charging function.

[0178] Exemplarily, when the wireless reverse charging function of the electronic device 30 is turned off, in response to the remaining power of the electronic device 30 being greater than the first power threshold and the remaining power of the second component 40 being less than or equal to the second power threshold, the electronic device 30 turns on the wireless reverse charging function.

[0179] When the electronic device 30 turns on the wireless reverse charging function, the electronic device 30 can switch the coil 31 from the state of receiving magnetic energy to the state of sending magnetic energy. When the electronic device 30 turns off the wireless reverse charging function, the electronic device 30 can switch the coil 31 from the state of sending magnetic energy to the state of receiving magnetic energy.

[0180] S102, the electronic device 30 sends control information, and correspondingly, the second component 40 receives the control information.

[0181] The connection line (first loop) between the coil 202 and the coil 204 in the second component 40 can be in a connected state by default, and the connection line (second loop) between the coil 204 and the energy storage unit 210 in the second component 40 can be in a disconnected state by default, or in other words, the first control unit 212 can be in a closed state by default, and the second control unit 218 can be in a closed state by default. Accordingly, the second component 40 can be regarded as an energy transfer device. In this state, the electrical energy of the charging base 10 is transmitted to the electronic device 30 via the second component 40.

[0182] The control information may be information used to control the connection or disconnection of the first and second circuits. When the first circuit is connected and the second circuit is disconnected, the control information may be used to control the disconnection of the first circuit and the connection of the second circuit. When the first circuit is disconnected and the second circuit is connected, the control information may be used to control the connection of the first circuit and the disconnection of the second circuit.

[0183] The above technical solution can also be understood as follows: in response to turning on the wireless reverse charging function of the electronic device 30, the electronic device 30 can send first control information to the second component 40, and the first control information can be used to control the disconnection of the first circuit and the connection of the second circuit. In response to turning off the wireless reverse charging function of the electronic device 30, the electronic device 30 can send second control information to the second component 40, and the second control information can be used to control the connection of the first circuit and the disconnection of the second circuit.

[0184] In some examples, the electronic device 30 may include a first communication circuit, and the second component 40 may include a second communication circuit. The aforementioned control information may be sent by the first communication circuit of the electronic device 30 and received by the second communication circuit of the second component 40. In the aforementioned S101, the second information that can be used to indicate the remaining power of the second component 40 may also be implemented through communication between the first communication circuit and the second communication circuit.

[0185] For example, the communication between the first communication circuit and the second communication circuit may be accomplished based on a Bluetooth communication protocol, a near field communication protocol, or other wireless communication protocols, which is not limited in this application.

[0186] S103 , the second component 40 disconnects the first circuit and connects the second circuit, or the second component 40 connects the first circuit and disconnects the second circuit.

[0187] In some examples, a first control unit 212 is provided on the first loop, and a second control unit 218 is provided on the second loop. The control information can be used to instruct the first control unit 212 and the second control unit 218 to perform corresponding operations, respectively.

[0188] For example, the first control information may be used to instruct the first control unit 212 to disconnect the first loop, and the first control information may also be used to instruct the second control unit 218 to connect the second loop. The second control information may be used to instruct the first control unit 212 to connect the first loop, and the second control information may also be used to instruct the second control unit 218 to disconnect the second loop.

[0189] For example, the first control unit 212 and the second control unit can both realize the function of a single-pole double-throw switch. When the first control unit 212 is disconnected and the second control unit 218 is connected, the first control information can be used to control the aforementioned first control unit 212 to be closed and the second control unit 218 to be disconnected, thereby realizing the connection of the first circuit and the disconnection of the second circuit; when the first control unit 212 is closed and the second control unit 218 is disconnected, the second control information can be used to control the aforementioned first control unit 212 to be disconnected and the second control unit 218 to be closed, thereby realizing the disconnection of the first circuit and the connection of the second circuit.
