[0035] The technical solutions in the embodiments of this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; the word "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0037] To more clearly introduce the wireless charging method and related apparatus provided in the embodiments of this application, the relevant content of wireless charging technology (WCT) will be introduced first below.

[0038] Wireless charging methods can include: magnetic coupling via electromagnetic induction, magnetic resonance via near-field resonance of electromagnetic waves, electric field coupling via electric field energy transfer, and microwave transmission via electromagnetic wave radiation, etc. In most cases, electronic devices typically achieve wireless charging through magnetic coupling via electromagnetic induction, which will be used as an example below.

[0039] Wireless charging involves a transmitting device (e.g., a subsequent wireless charging device 200) and a receiving device (e.g., a subsequent electronic device 100), wherein the transmitting device includes a transmitting coil and the receiving device includes a receiving coil. The principle of wireless charging is as follows: First, the transmitting device passes a changing current through its transmitting coil, which generates a changing magnetic field. Then, because the receiving coil is in the changing magnetic field, the magnetic flux through it also changes continuously, thus inducing an electromotive force in the receiving device, which in turn induces a current in its receiving coil. Finally, the receiving device can convert this induced current in its receiving coil into direct current and use it to charge its battery, thereby achieving wireless charging from the transmitting end to the receiving end.

[0040] The Wireless Power Consortium (WPC) has developed the Qi protocol, an interconnect standard for short-range (40mm, 1.6-inch) low-power wireless inductive power transfer. This protocol is primarily used for wireless charging of mobile devices. Qi protocol data communication mainly employs backscatter modulation, a type of load modulation. During wireless charging, the receiving device needs to notify the transmitting device whether charging power and / or fan speed needs adjustment, and whether charging is complete. The receiving device can transmit this information to the transmitting device through load modulation. This load modulation involves the receiving device using a switching modulation resistor or modulation capacitor in the circuit to modulate the load, allowing the transmitting device to detect periodic changes in the current or voltage on the transmitting coil. The transmitting device then demodulates the information transmitted by the receiving device from these periodic changes.

[0041] The following describes a wireless charging communication process. This process includes: a selection phase, a connection establishment phase, an identification and configuration phase, and an energy transfer phase. For details, please refer to the following content.

[0042] First, during the selection phase, the transmitting device needs to detect the presence of a receiving device. Specifically, the transmitting device can periodically apply a certain amount of current to its transmitting coil. When the transmitting device detects a change in the current magnitude in its transmitting coil, a receiving device is present. This is because the receiving device contains metal, which affects the magnitude of the current generated by the transmitting coil.

[0043] Then, during the connection establishment phase, the communication function of the receiving device can be activated. Specifically, the transmitting device can apply current to its transmitting coil, a current larger than that in the selection phase described above. Because the transmitting coil generates a magnetic field, a current is induced in the receiving coil of the receiving device. The receiving device can then activate the communication function and send signal strength indication information to the transmitting device via load modulation. After receiving this strength indication information, the transmitting device can maintain power to sustain the signal strength.

[0044] Next, during the identification and configuration phase, the receiving device and the transmitting device exchange information multiple times to determine the charging power and / or fan speed. This information exchange can be achieved by changing the current or load modulation of the transmitting device.

[0045] Finally, during the energy transfer phase, the transmitting device connects a current to the transmitting coil to ensure the determined charging power. The receiving device rectifies and filters the current generated in the receiving coil to obtain a DC current voltage. During the charging process, the receiving device can also periodically send information to the transmitting device, which may include, for example, increasing or decreasing the charging power, or ending charging, allowing the transmitting device to make corresponding adjustments.

[0046] Figure 1 This is a schematic diagram of a wireless charging system 10 provided in an embodiment of this application.

[0047] like Figure 1 As shown, the wireless charging system 10 may include an electronic device 100 and a wireless charging device 200.

[0048] In this embodiment of the application, the wireless charging device 200 may be a wireless charging base ( Figure 1 (As shown in the image), a power bank or vehicle mount, the electronic device 100 can be charged by the wireless charging device 200.

[0049] In this embodiment of the application, the device type of electronic device 100 can be any of the following: mobile phone, tablet computer, handheld computer, desktop computer, laptop computer, ultra-mobile personal computer (UMPC), netbook, cellular phone, personal digital assistant (PDA), as well as smart home devices such as smart screens and smart speakers, wearable devices such as smart bracelets, smartwatches, and smart glasses, extended reality (XR) devices such as augmented reality (AR), virtual reality (VR), and mixed reality (MR), in-vehicle devices, or smart city devices.

[0050] When the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can be stably attracted by the wireless charging device 200 and will not come loose. The wireless charging device 200 can use an alternating magnetic field to achieve energy transfer between the wireless charging device 200 and the electronic device 100, thereby charging the electronic device 100. Specifically, the DC power in the wireless charging device 200 can be converted into AC power through a full-bridge inverter circuit. The AC power can generate a magnetic field through the coil (i.e., the aforementioned transmitting coil) in the wireless charging device 200. When the coil (i.e., the aforementioned receiving coil) in the electronic device 100 is close to the wireless charging device 200, the resonant circuit in the electronic device 100 can generate induced AC power. The electronic device 100 can convert this AC power into DC power through a full-bridge rectifier circuit to provide power to the electronic device 100, thereby charging the electronic device 100.

[0051] As described above, the wireless charging device 200 and the electronic device 100 can communicate based on the Qi protocol.

[0052] When the wireless charging device 200 sends a data packet to the electronic device 100, the wireless charging device 200 can use frequency-shift keying (FSK) modulation to communicate (i.e., using digital signals to control the frequency change of the carrier signal). The electronic device 100 can demodulate the frequency change of the carrier signal to obtain the data packet sent by the wireless charging device 200.

[0053] When the electronic device 100 sends a data packet to the wireless charging device 200, the electronic device 100 can use amplitude modulation (AM) to communicate based on the aforementioned load modulation method (even if the amplitude of the carrier signal changes according to a certain rule, the frequency remains unchanged). The wireless charging device 200 can demodulate the amplitude change of the carrier signal and thus obtain the data packet sent by the electronic device 100.

[0054] When using the wireless charging device 200 to wirelessly charge the electronic device 100, the electronic device 100 can be placed on the surface of the wireless charging device 200 with the display screen facing up and the back of the device containing the rear camera facing down.

[0070] The charging management module 106C may include a wireless charging management module for power conversion (i.e., converting the received electrical energy into DC power usable inside the electronic device 100) and charging management (e.g., monitoring the charging status, ensuring safe charging, and preventing overcharging, over-discharging, etc.) during the wireless charging process.

[0073] It should be noted that, Figure 2AThis is for illustrative purposes only and does not constitute any limitation on this application.

[0074] Figure 2B This is a schematic diagram of the hardware structure of a wireless charging device 200 provided in the embodiments of this application.

[0075] Figure 2B A schematic diagram of the hardware structure of the wireless charging device 200 is shown.

[0076] like Figure 2B As shown, the wireless charging device 200 may include: a controller 210, an interface 220 (optional), a wireless charging module 230, a coil 240 (i.e., the aforementioned transmitter coil), and a fan 250, etc.

[0077] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the wireless charging device 200. In other embodiments of this application, the wireless charging device 200 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0078] The controller 210 may include one or more wireless charging chips, which serve as the nerve center and command center of the wireless charging device 200. It can generate operation control signals according to the instruction operation code and timing signal to complete the control of fetching and executing instructions.

[0079] In some embodiments, controller 210 may include interface 220 (optionally), etc.

[0080] For example, interface 220 can be an interface compliant with USB standards, specifically a Mini USB interface, a MicroUSB interface, a USB Type-C interface, etc. Interface 220 can be used to connect a charger to charge the wireless charging device 200, and can also be used for data transmission between the wireless charging device 200 and peripheral devices.

[0081] The wireless charging module 230 can be used to pass a changing current through the coil 240, causing the coil 240 to generate a changing magnetic field, which in turn causes an induced current in the coil of the electronic device 100 that is close to the wireless charging device 200, so as to wirelessly charge the electronic device 100.

[0082] The fan 250 can be mounted on the base of the wireless charging device 200. In one possible implementation, the fan can also be mounted externally to the wireless charging device 200 and connected to it via a wired or wireless connection. When the wireless charging device 200 wirelessly charges the electronic device 100, the fan 250 can be used to dissipate heat from the wireless charging device 200 and / or the electronic device 100. The rotational speed of the fan 250 is related to the power of the wireless charging device 200; the higher the power of the wireless charging device 200, the higher the rotational speed of the fan 250.

[0083] It is understood that the interface connection relationships between the modules illustrated in the embodiments of this application are merely illustrative and do not constitute a structural limitation on the wireless charging device 200. In other embodiments of this application, the wireless charging device 200 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0084] Figure 3A This is a schematic diagram illustrating wireless charging noise interference as provided in an embodiment of this application.

[0085] like Figure 3A As shown, in some application scenarios, when electronic device 100 is placed on wireless charging device 200 for wireless charging, wireless charging device 200 often uses a relatively high power (e.g., greater than 50W) to wirelessly charge electronic device 100. However, high-power wireless charging has the problems of high energy loss and high heat generation, which requires heat dissipation through fan 250 installed on wireless charging device 200. If the noise generated by fan 250 is not well controlled, it will interfere with the user's daily life.

[0086] Therefore, this application provides a wireless charging method in which, when the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can detect its state and / or its environment. At this time, the wireless charging device 200 wirelessly charges the electronic device 100 at a power of W1, and the fan 250 in the wireless charging device 200 cools the wireless charging device 200 and / or the electronic device 100 at a rotation speed of Q1. Then, based on its state and / or environment, the electronic device 100 can control the wireless charging device 200 to wirelessly charge the electronic device 100 at a power of W2, and control the fan 250 in the wireless charging device 200 to cool the wireless charging device 200 and / or the electronic device 100 at a rotation speed of Q2.

[0087] Among them, the power W2 can be less than the power W1, and the speed Q2 can be less than the speed Q1.

[0088] Power W1 is the minimum value between the maximum power supported by electronic device 100 and the maximum power supported by wireless charging device 200 during wireless charging. Rotation speed Q1 is the rotation speed corresponding to power W1. For example, during wireless charging, if electronic device 100 can support a maximum power of 40W and wireless charging device 200 can support a maximum power of 60W, then power W1 is 40W.

[0089] As can be seen, by implementing the wireless charging method provided in this application, the electronic device 100 can control the power of the wireless charging device 200 according to different environments, thereby controlling the speed of the fan 250. In some environments, the wireless charging device 200 can wirelessly charge the electronic device 100 at a lower power, so the fan 250 can also operate at a lower speed. In this way, not only can the power of the wireless charging device 200 when charging the electronic device 100 be flexibly adjusted, saving the power consumption of the wireless charging device 200, but also reducing the noise interference of the fan 250.

[0090] Figures 3B-3E A set of schematic diagrams showing the adjustment of the power of the wireless charging device 200 and the speed of the fan 250 according to different environments provided in the embodiments of this application.

[0091] like Figure 3B As shown, when the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can detect its status and / or its environment through one or more devices. At this time, the wireless charging device 200 can charge the electronic device 100 at power A1, and the fan 250 can dissipate heat from the wireless charging device 200 and / or the electronic device 100 at a rotation speed B1. Here, power A1 is the minimum value between the maximum power that the electronic device 100 can support and the maximum power that the wireless charging device 200 can support during wireless charging. Rotation speed B1 is the rotation speed corresponding to power A1.

[0092] When the state of the electronic device 100 and / or its environment is determined to be bright, quiet, stationary (e.g., indoor charging dock), and screen off, the electronic device 100 can control the wireless charging device 200 to charge the electronic device 100 at power A2, and the fan 250 to dissipate heat from the wireless charging device 200 and / or the electronic device 100 at a speed B2. Wherein, power A2 is less than power A1, and speed B2 is less than speed B1.

[0093] like Figure 3CAs shown, when the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can detect its status and / or its environment through one or more devices. At this time, the wireless charging device 200 can charge the electronic device 100 at power A1, and the fan 250 can dissipate heat from the wireless charging device 200 and / or the electronic device 100 at a speed B1.

[0094] When the state of the electronic device 100 and / or the environment is determined to be bright, noisy, static, or screen off, the wireless charging device 200 still charges the electronic device 100 at power A1, and the fan 250 still cools the wireless charging device 200 and / or the electronic device 100 at speed B1.

[0095] like Figure 3D As shown, when the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can detect its status and / or its environment through one or more devices. At this time, the wireless charging device 200 can charge the electronic device 100 at power A1, and the fan 250 can dissipate heat from the wireless charging device 200 and / or the electronic device 100 at a speed B1.

[0096] When the state and / or environment of the electronic device 100 are determined to be dim light, quiet, still, or with a bright screen, the electronic device 100 can control the wireless charging device 200 to charge the electronic device 100 at power A3, and the fan 250 to dissipate heat from the wireless charging device 200 and / or the electronic device 100 at speed B3. Wherein, power A3 is less than power A1, and speed B3 is less than speed B1.

[0097] like Figure 3E As shown, when the wireless charging device 200 wirelessly charges the electronic device 100, the electronic device 100 can detect its status and / or its environment through one or more devices. At this time, the wireless charging device 200 can charge the electronic device 100 at power A1, and the fan 250 can dissipate heat from the wireless charging device 200 and / or the electronic device 100 at a speed B1.

[0098] When the state of electronic device 100 and / or its environment is determined to be dim light, quiet, still, or screen off, electronic device 100 can control wireless charging device 200 to charge electronic device 100 at power A4, and fan 250 to dissipate heat from wireless charging device 200 and / or electronic device 100 at speed B4. Wherein, power A4 is less than power A1, and speed B4 is less than speed B1.

[0099] It should be noted that, Figures 3B-3EThis is only used as an example to explain this application. In actual applications, the environment in which the electronic device 100 is located may be different from the example above. Subsequent embodiments will describe this in detail.

[0100] Figures 4A-4E A set of user interface diagrams provided for embodiments of this application.

[0101] like Figure 4A As shown, the electronic device 100 can display a desktop 410. This desktop 410 can display a page containing application icons, including icons for multiple applications (e.g., weather app icons, stock app icons, calculator app icons, settings app icons, email app icons, desktop customization app icons, music app icons, video app icons, browser app icons, etc.). A status bar 411 is displayed in the upper portion of the desktop 410. This status bar 411 can include one or more indicators, such as one or more mobile communication signal (also known as cellular signal) strength indicators, battery status indicators, time indicators, Wi-Fi signal indicators, etc.

[0102] When the wireless charging device 200 wirelessly charges the electronic device 100 at a power less than W1 (i.e., low-noise charging mode is enabled), the electronic device 100 can display a prompt window 412 on the desktop 410. This prompt window 412 can be used to inform the user that the wireless charging device 200 is currently wirelessly charging the electronic device 100 at a power less than W1. At this time, the fan 250's rotational speed is also less than Q1.

[0103] The prompt window 412 can display the text message "Low-noise charging mode is enabled," and includes an exit control 412A. In response to a touch operation (e.g., a click) on the exit control 412A, the electronic device 100 can control the wireless charging device 200 to wirelessly charge the electronic device 100 at a power of W1, at which time the fan 250 rotates at a speed of Q1.

[0104] like Figure 4B As shown, in one possible implementation, when Figure 4A If the prompt window 412 displays that the specified time T2 has been exceeded (e.g., 1 second or 2 seconds), and the wireless charging device 200 is still wirelessly charging the electronic device 100 at a power less than W1, the electronic device 100 can display a charging indicator 411A and a low noise indicator 411B in the status bar area. That is, when both the charging indicator 411A and the low noise indicator 411B are displayed in the status bar area, it prompts the user that the wireless charging device 200 is wirelessly charging the electronic device 100 at a power less than W1. At this time, the fan speed 250 is also still less than the speed Q1.

[0105] like Figure 4C As shown, when the electronic device 100 displays the charging indicator 411A and the low noise indicator 411B, the electronic device 100 can receive a touch operation (e.g., swiping down) performed by the user on the status bar area.

[0106] like Figure 4D As shown, in response to Figure 4C Upon a touch operation (e.g., swiping down), the electronic device 100 can display a notification interface 420. This notification interface can display one or more notification windows, which may include a prompt window 421. The prompt window 421 can be used to prompt the user that the wireless charging device 200 is wirelessly charging the electronic device 100 at a power less than W1, at which time the fan 250's speed is also less than Q1. The prompt window 421 displays the text message "Low-noise charging mode is enabled" and may include a control 421A. In response to a touch operation (e.g., clicking) applied to the control 421A, the electronic device 100 can control the wireless charging device 200 to wirelessly charge the electronic device 100 at a power of W1, at which time the fan 250's speed is Q1.

[0107] like Figure 4E As shown, in yet another possible implementation, when Figure 4A If the notification window 412 indicates that the specified time T2 has been exceeded and the wireless charging device 200 is still wirelessly charging the electronic device 100 at a power less than W1, the electronic device 100 can display a notification capsule 413 on its display screen. For example, the notification capsule 413 can be displayed at the top of the display screen of the electronic device 100. This notification capsule 413 can be used to remind the user that the wireless charging device 200 is currently wirelessly charging the electronic device 100 at a power less than W1, and at this time, the speed of the fan 250 is also less than the speed Q1.

[0108] Electronic device 100 can receive a touch operation (e.g., a click) performed by a user on the notification capsule 413. In response to such a touch operation, electronic device 100 can de-display the notification capsule 413 and display a notification window 412, the description of which can be found above. Figure 4A The illustrated embodiment. The prompt window 412 may include an exit control 412A. In response to a touch operation (e.g., a click) on the exit control 412A, the electronic device 100 may control the wireless charging device 200 to wirelessly charge the electronic device 100 at a power of W1, at which time the fan 250 also rotates at a speed of Q1.

[0109] Optionally, the display screen of the electronic device 100 can be a punch-hole screen, with a front-facing camera typically placed in the punch-hole location, and the front-facing camera can be located at the top of the display screen. To fully utilize the display area, the electronic device 100 displays a notification capsule 413 around the punch-hole location at the top of the display screen. The punch-hole location can be located in the center of the notification capsule 413, while the non-center area of ​​the notification capsule 413 can display low-noise charging notification information (such as the text "Low-noise charging mode"), etc. Since the display color of the punch-hole location is black, the background color of the notification capsule 413 can also be set to black, making it difficult for users to notice the punch-hole location. The notification capsule 413 can float on top of other interfaces.

[0110] First, we introduce a wireless charging method provided in the embodiments of this application.

[0111] Figure 5A This is a schematic diagram illustrating a specific implementation of a wireless charging method provided in an embodiment of this application.

[0112] like Figure 5A As shown, the specific implementation of this wireless charging method may include:

[0113] S501: When electronic device 100 approaches wireless charging device 200, wireless charging device 200 wirelessly charges electronic device 100 with power W1.

[0114] When the electronic device 100 is close to the wireless charging device 200, the electronic device 100 and the wireless charging device 200 can negotiate to wirelessly charge the electronic device 100 with power W1 and to dissipate heat from the electronic device 100 and / or the wireless charging device 200 with rotation speed Q1.

[0115] Here, power W1 is the minimum value between the maximum power that the electronic device 100 can support and the maximum power that the wireless charging device 200 can support during wireless charging. Power W1 can be referred to as the first power.

[0116] The method by which the wireless charging device 200 wirelessly charges the electronic device 100 can be referred to the foregoing description.

[0117] S502: The wireless charging device 200 controls the fan to operate at a speed of Q1.

[0118] Among them, the rotational speed Q1 can be referred to as the first rotational speed.

[0119] S503: Electronic device 100 detects the status of electronic device 100 and / or its environment.

[0120] Specifically, the electronic device 100 can detect its state and / or its environment through one or more devices. These one or more devices include at least one of the following: a display screen, an ambient light sensor, a microphone, a gyroscope sensor, and an accelerometer sensor.

[0121] Figure 5B This is a schematic diagram of the device used in an electronic device 100 provided in an embodiment of this application.

[0122] like Figure 5B As shown, the electronic device 100 can receive ambient sound through a microphone to identify whether it is in a quiet or noisy environment; the electronic device 100 can sense the ambient light intensity around it through an ambient light sensor to identify whether it is in a bright or dark environment; the electronic device 100 can identify whether it is in motion or stationary state through a gyroscope sensor and an accelerometer sensor; and the electronic device 100 can determine whether the display screen is currently on or off / off.

[0123] In this context, "screen-on state" refers to the state where all pixels on the display screen (also known as the screen) are lit to show the interface. In this state, the electronic device 100 can provide some or all of its functions, including but not limited to: answering and hanging up calls, adjusting music volume, launching the camera application, and turning airplane mode on / off. "Screen-off state" refers to the state where the display of the electronic device 100 is in sleep mode, with no interface elements displayed, but other devices and programs function normally. "Screen-off state" refers to the state where some pixels on the display screen are lit to show interface elements (e.g., a screen-off image, battery icon, time, etc.).

[0124] S504: Electronic device 100 determines power W2 and rotational speed Q2 based on the state of electronic device 100 and / or its environment.

[0125] The electronic device 100 may pre-store a mapping record 11, which records the mapping relationship between the state and / or environment of the electronic device 100 and one or more specified powers and one or more specified speeds. The electronic device 100 can determine the power W2 and speed Q2 corresponding to the state and / or environment of the electronic device 100 from the mapping record 11.

[0126] Specifically, the implementation method of the electronic device 100 detecting the state / environment of the electronic device 100 through one or more devices, and determining the power W2 and rotational speed Q2 based on the state / environment of the electronic device 100, will be described in detail in subsequent embodiments, and will not be repeated here.

[0127] Among them, power W2 is called the second power, and speed Q2 is called the second speed.

[0128] S505: Electronic device 100 determines whether the power W2 is less than the power W1.

[0129] S506: When the power W2 is less than the power W1, the electronic device 100 sends a first data packet to the wireless charging device 200. This first data packet may carry the power W2 and the rotational speed Q2.

[0130] The communication method for the electronic device 100 to send data packets to the wireless charging device 200 can be referred to the foregoing description, and will not be repeated here.

[0131] S507: In response to the received first data packet, the wireless charging device 200 wirelessly charges the electronic device 100 with power W2.

[0132] S508: The wireless charging device 200 controls the fan to operate at a speed of Q2.

[0133] Among them, the rotational speed Q2 is less than the rotational speed Q1.

[0134] S509: Electronic device 100 determines whether the display screen prompts the user that it is currently in low-noise charging mode.

[0135] The first notification method may include, but is not limited to, one or more of the following: charging indicator (e.g., charging symbol) Figure 4B The charging indicator 411A and the low noise indicator (as shown) are shown. Figure 4B The low noise indicator 411B shown), and the prompt capsule (such as...) Figure 4E (See the indicated capsule 413). Low-noise charging mode refers to: the wireless charging device 200 wirelessly charges the electronic device 100 with a power less than W1, at which time the fan speed is less than the speed Q1.

[0136] S510: When the display screen does not indicate to the user that the device is currently in low-noise charging mode in the first manner, the electronic device 100 displays a low-noise charging prompt message and an exit control in the second manner. The exit control is used to exit the low-noise charging mode.

[0137] The second notification method can be a notification window, which can be, for example, as described above. Figure 4A The prompt window 412 shown can display the low-noise charging prompt message as the text "Low-noise charging mode is enabled," and the exit control can be the aforementioned... Figure 4A The exit control 412A shown can be used to indicate to the user that the user is currently in low-noise charging mode.

[0138] S511: Electronic device 100 determines whether a first operation acting on the exit control has been detected.

[0139] S512: When the first operation is detected, in response to the first operation, the electronic device 100 sends a second data packet to the wireless charging device 200. The second data packet carries power W1 and rotational speed Q1.

[0140] S513: In response to the received second data packet, the wireless charging device 200 wirelessly charges the electronic device 100 with power W1.

[0141] S514: Wireless charging device 200 controls the fan to operate at speed Q1.

[0142] Steps S509 to S514 are optional.

[0143] In one possible implementation, when the electronic device 100 determines that the power W2 is equal to the power W1, the electronic device 100 starts execution from step S503 at intervals of a specified duration T3 (e.g., 10 minutes or 15 minutes).

[0144] In one possible implementation, when the electronic device 100 determines that the display screen indicates to the user that it is currently in low-noise charging mode in a first prompt mode, the electronic device 100 does not indicate to the user that it is currently in low-noise charging mode in a second prompt mode, but continues to maintain the display in the first prompt mode. Then, the electronic device 100 executes S511 to S514. In the first prompt mode, the electronic device 100 can receive and respond to the second operation (such as...). Figure 4C The touch operation shown, or as Figure 4E (As shown in the touch operation), switch to the second prompt mode and execute S510 to S514.

[0145] In one possible implementation, when the electronic device 100 determines that no first operation acting on the exit control has been detected, the electronic device 100 starts executing from step S503 at intervals of a specified duration T4 (e.g., 5 minutes, 3 minutes, etc.). The specified duration T4 can be less than the specified duration T3.

[0146] Figure 6 This is a schematic diagram of the device architecture of a wireless charging system 10 provided in an embodiment of this application.

[0147] like Figure 6 As shown, the device architecture of the wireless charging system 10 may include: an electronic device 100 and a wireless charging device 200.

[0148] I. Electronic equipment 100

[0149] The electronic device 100 may include a processor, a charging management module, and a device module. The processor may include: a data transmission module, a power determination module, a device information reading module, a UI display module, and registers. Wherein:

[0150] The device module may include one or more devices, which may include one or more of the following: a display screen, a microphone, an ambient light sensor, a gyroscope sensor, and an accelerometer sensor. The display screen can detect whether it is on or off (in one possibility, it can also detect a screen-off state). The microphone can detect whether the electronic device 100 is in a quiet or noisy state. The ambient light sensor can detect whether the environment in which the electronic device 100 is located is bright or dark. The gyroscope sensor and the accelerometer sensor can detect whether the electronic device 100 is in motion or stationary.

[0151] The device information reading module can be used to receive status indication information sent by one or more devices, and the one or more status indication information can be used to indicate the status and / or environment of the electronic device 100.

[0152] Then, the device information reading module can assign values ​​to the registers based on one or more received status indications. The values ​​of the registers can be used to indicate the status and / or environment of the electronic device 100.

[0153] The power determination module can be used to read the value of the register and determine the power W2 and fan speed Q2 of the wireless charging device 200 based on the register value. Alternatively, the power determination module can determine the power W1 and fan speed Q1 of the wireless charging device 200 in response to a received first operation.

[0154] Then, the power determination module can control the data transmission module to send data packets (e.g., the aforementioned first data packet, second data packet, etc.) to the wireless charging device 200. The data packets can carry a specified power (e.g., the aforementioned power W1, power W2, etc.) and a specified rotation speed (e.g., rotation speed Q1, rotation speed Q2, etc.).

[0155] The UI display module can be used to prompt the user that the device is currently in low-noise charging mode using a first prompt method and a second prompt method, determine whether the display screen prompts the user that the device is currently in low-noise charging mode using the first prompt method, and whether the first operation has been received. When the UI display module receives the first operation, it can control the power determination module to determine the power W1 of the wireless charging device 200 and the fan speed Q1.

[0156] The charging management module can be used to coordinate with the wireless charging device 200 to wirelessly charge the electronic device 100.

[0157] II. Wireless charging device 200

[0158] The wireless charging device 200 may include a controller, a wireless charging module, and a fan. The controller may include a data receiving module. Wherein:

[0159] The wireless charging module can wirelessly charge the electronic device 100 based on a specified power (e.g., power W1, power W2, etc.).

[0160] The data receiving module can receive data packets sent by the electronic device 100 and parse out the specified power and specified rotation speed carried in the data packets. Then, the data receiving module can control the wireless charging module to wirelessly charge the electronic device 100 based on the specified power, and control the fan to operate at a specified rotation speed to dissipate heat from the wireless charging device 200 and the electronic device 100.

[0161] Figure 7 This is a schematic diagram of the module interaction process of a wireless charging method provided in an embodiment of this application.

[0162] S701: When the electronic device 100 and the wireless charging device 200 are close together, the charging management module of the electronic device 100 can work together with the wireless charging module of the wireless charging device 200 to wirelessly charge the electronic device 100 with a power of W1.

[0163] For an explanation of this step, please refer to the description in S501 above.

[0164] S702: The fan operates at speed Q1.

[0165] S703: The device information reading module receives status indication information of one or more devices sent by the device module every specified period T1 (e.g., 10 seconds or 7 seconds).

[0166] For example, one or more devices in the device module may include a microphone, an ambient light sensor, a gyroscope sensor, an accelerometer sensor, and a display screen.

[0167] Specifically, the operation of the above-mentioned device in the embodiments of this application is explained as follows:

[0168] 1. Microphone

[0169] The microphone can receive sounds from the surrounding environment of the electronic device 100 and determine the current environment of the electronic device 100 based on the decibel level of the received sound. When the received sound is higher than a specified decibel level, the microphone determines that the electronic device 100 is currently in a noisy environment; when the received sound is lower than the specified decibel level, the microphone determines that the electronic device is currently in a quiet environment.

[0170] Then, the microphone can send status indication information 1 to the device information reading module. If the status indication information 1 carries the value M1, it indicates that the electronic device 100 is currently in a noisy environment; if the status indication information 1 carries the value M2, it indicates that the electronic device 100 is currently in a quiet environment.

[0171] II. Ambient Light Sensor

[0172] An ambient light sensor is used to sense the ambient light intensity around the electronic device 100. It can detect the value of the ambient light intensity and determine the current environment of the electronic device 100 based on the value of the ambient light intensity. When the detected ambient light intensity value is greater than a specified value of 1, the ambient light sensor determines that the electronic device 100 is in a bright light environment; when the detected ambient light intensity value is less than the specified value of 1, the ambient light sensor determines that the electronic device 100 is in a dark light environment.

[0173] Then, the ambient light sensor can send status indication information 2 to the device information reading module. If the status indication information 2 carries the value H1, it indicates that the current electronic device 100 is in a bright light environment; if the status indication information 2 carries the value H2, it indicates that the current electronic device 100 is in a dark light environment.

[0174] III. Gyroscope Sensor and Accelerometer Sensor

[0175] The gyroscope sensor and accelerometer sensor can detect acceleration values ​​and acceleration variation patterns on three axes (x-axis, y-axis, and z-axis) and determine the state of the electronic device 100. If the gyroscope sensor and accelerometer sensor detect that the electronic device 100 is in a stationary state (e.g., as mentioned above)... Figure 3B The indoor charging dock shown can send status indication information 3, carrying value L1, to the device information reading module to indicate that the current electronic device 100 is in a stationary state; if the gyroscope sensor and the accelerometer sensor detect that the electronic device 100 is in motion (e.g., in a vehicle charging dock), it can send status indication information 3, carrying value L2, to the device information reading module to indicate that the current electronic device 100 is in motion.

[0176] IV. Display Screen

[0177] The display screen can be used to determine whether the display screen is currently on, off, or in a non-on state. If the display screen determines that the display screen is on, it can send status indication information 4, carrying the value P1, to the device information reading module to indicate that the current electronic device 100 is in a on state; if the display screen determines that the display screen is off, it can send status indication information 4, carrying the value P2, to the device information reading module to indicate that the current electronic device 100 is in a non-on state.

[0178] It is understood that the status indication information sent by the above-mentioned devices can indicate the status of the electronic device 100 and / or its environment.

[0179] S704: The device information reading module assigns values ​​to registers based on the status indication information of one or more devices.

[0180] When the device information reading module receives status indication information from one or more devices, the device information reading module assigns a value to the register. That is to say, the value of the register is updated every specified period T1.

[0181] Specifically, the register can be a 4-bit register reg[3:0]. Here, reg[0] represents the 1st bit, reg[1] represents the 2nd bit, reg[2] represents the 3rd bit, and reg[3] represents the 4th bit.

[0182] reg[0] indicates the surrounding environment of electronic device 100 detected by the microphone. Its address is associated with pointer 1. That is to say, when it is necessary to assign a value to reg[0], the device information reading module can find the address of reg[0] through pointer 1 and assign a value to it. Among them, when reg[0] = 1, it indicates that electronic device 100 is currently in a noisy environment, and when reg[0] = 0, it indicates that electronic device 100 is currently in a quiet environment.

[0183] reg[1] indicates the state of electronic device 100 detected by the gyroscope sensor and accelerometer sensor (which can be simply referred to as A+G). Its address is associated with pointer 2. That is to say, when it is necessary to assign a value to reg[1], the device information reading module can find the address of reg[0] through pointer 2 and assign a value to it. Among them, when reg[1] = 1, it indicates that electronic device 100 is currently in motion, and when reg[1] = 0, it indicates that electronic device 100 is currently in a stationary environment.

[0184] reg[2] indicates the ambient light intensity around the electronic device 100 as sensed by the ambient light sensor. Its address is associated with pointer 3. That is to say, when it is necessary to assign a value to reg[2], the device information reading module can find the address of reg[2] through pointer 3 and assign a value to it. Among them, when reg[2] = 0, it indicates that the electronic device 100 is currently in a dark environment, and when reg[2] = 1, it indicates that the electronic device 100 is currently in a bright environment.

[0185] reg[3] indicates the display state of the electronic device 100. Its address is associated with pointer 4. That is to say, when it is necessary to assign a value to reg[3], the device information reading module can find the address of reg[3] through pointer 4 and assign a value to it. When reg[3] = 0, it indicates that the display of the electronic device 100 is in a screen-off or screen-off state (i.e., non-screen-on state), and when reg[3] = 1, it indicates that the display is in a screen-on state.

[0186] For example, the mapping relationship between the state / surrounding environment of the electronic device 100 detected by each device and the value of each binary bit in the register is shown in Table 1:

[0187] Table 1

[0188]

[0189] It should be noted that when the electronic device 100 and the wireless charging device 200 execute S701, the electronic device 100 can initialize four pointers (pointer 1 to pointer 4) and registers.

[0190] S705: The power determination module can read the value of the register from the register.

[0191] Reading the value of the register means reading the value of 4 binary bits in the register.

[0192] S706: The power determination module determines the power W2 and speed Q2 corresponding to the value in the register.

[0193] Understandably, the power determination module can determine the power W2 and speed Q2 corresponding to the register value from the mapping record 11. The value of the four binary bits of the register is used to indicate the state and / or environment of the electronic device 100. The mapping record 11 can specifically record the mapping relationship between the register value and its corresponding specified power and specified speed. That is, the mapping record 11 records the mapping relationship between the state and / or environment of the electronic device 100 and one or more specified power and one or more specified speeds.

[0194] In other words, the electronic device 100 actually determines its state and / or environment by the value of the register.

[0195] In one possible implementation, the power determination module can read the register value N times (N>=2, preferably 6), take the average or median value, and then determine the power and speed corresponding to the register value from the mapping record 11; in another possible implementation, the power determination module can read the current register value only once, and determine the power and speed corresponding to the register value from the mapping record 11 based on the currently read register value.

[0196] Figure 8 This is a schematic diagram illustrating the state and / or environment of an electronic device 100 and the values ​​of corresponding registers, provided in an embodiment of this application.

[0197] like Figure 8 As shown:

[0198] (1). When the electronic device 100 is in a bright, noisy, moving, or screen-off state, the value of the register is 0111;

[0199] When the electronic device 100 is in the on, quiet, motion, or screen off / screen-off state, the register value is 0110;

[0200] When the electronic device 100 is in a bright, noisy, static, or screen-off state, the register value is 0101;

[0201] When the electronic device 100 is in the on, quiet, static, or screen off state, the register value is 0100;

[0202] (2). When the electronic device 100 is in low light, noisy, moving, or screen off mode, the value of the register is 0011;

[0203] When the electronic device 100 is in low light, quiet, motion, or screen off mode, the register value is 0010;

[0204] When the electronic device 100 is in dim light, noisy, static, or screen off mode, the register value is 0001;

[0205] When the electronic device 100 is in dim light, quiet, static, or screen off mode, the register value is 0000;

[0206] (3). When the electronic device 100 is in a bright, noisy, moving, or screen-on state, the value of the register is 1111;

[0207] When the electronic device 100 is in the light-up, quiet, motion, or screen-on mode, the register value is 1110;

[0208] When electronic device 100 is in a bright, noisy, static, or screen-on state, the register value is 1101;

[0209] When electronic device 100 is in the light-up, quiet, stationary, or screen-on state, the register value is 1100;

[0210] (4). When the electronic device 100 is in low light, noisy, moving, or bright screen mode, the value of the register is 1011;

[0211] When the electronic device 100 is in low light, quiet, motion, or bright screen mode, the register value is 1010;

[0212] When electronic device 100 is in dim light, noisy, stationary, or with a bright screen, the value of the register is 1001;

[0213] When the electronic device 100 is in dim light, quiet, still, or bright screen mode, the register value is 1000.

[0214] Figure 8 This application is provided for illustrative purposes only and does not constitute a limitation thereof.

[0215] For example, mapping record 11 can be as shown in Table 2:

[0216] Table 2

[0217] Register value Specified power Specified speed Register value Specified power Specified speed 0x0:reg[3:0]=0000 5W 0 turns 0x8:reg[3:0] = 1000 15W 1000 RPM 0x1:reg[3:0]=0001 80W 3600 RPM 0x9:reg[3:0] = 1001 80W 3600 RPM 0x2:reg[3:0] = 0010 80W 3600 RPM 0xA:reg[3:0] = 1010 80W 3600 RPM 0x3:reg[3:0]=0011 80W 3600 RPM 0xB:reg[3:0] = 1011 80W 3600 RPM 0x4:reg[3:0]=0100 30W 2000 RPM 0xC:reg[3:0] = 1100 30W 2000 RPM 0x5:reg[3:0]=0101 80W 3600 RPM 0xD:reg[3:0] = 1001 80W 3600 RPM 0x6:reg[3:0] = 0110 80W 3600 RPM 0xE:reg[3:0]=1110 80W 3600 RPM 0x7:reg[3:0]=0111 80W 3600 RPM 0xF:reg[3:0]=1111 80W 3600 RPM

[0218] As can be seen from Table 2, when the register value is 0000, the corresponding power is 5W and the speed is 0 rpm; when the register value is 0100, the corresponding power is 30W and the speed is 2000 rpm; when the register value is 1000, the corresponding power is 15W and the speed is 1000 rpm; and when the register value is 1100, the corresponding power is 3W and the speed is 2000 rpm.

[0219] Table 2 is for illustrative purposes only and does not constitute any limitation.

[0220] S707: The power determination module determines whether the power W2 is less than the power W1.

[0221] S708: When the power W2 is less than the power W1, the power determination module sends a data transmission command 1 to the data transmission module. The data transmission command 1 may include the power W2 and the rotational speed Q2.

[0222] S709: The data transmission module encapsulates the power W2 and the rotational speed Q2 into a first data packet.

[0224] The first data packet carries power W2 and rotational speed Q2.

[0225] S711: The data receiving module parses the power W2 and rotational speed Q2 from the first data packet.

[0226] S712: The data receiving module sends a power adjustment command 1 to the wireless charging module.

[0227] The power adjustment command 1 may include power W2.

[0228] S713: The wireless charging module and charging management module wirelessly charge the electronic device 100 with a power of W2.

[0229] S714: The data receiving module sends a speed adjustment command 1 to the fan.

[0230] The speed adjustment command 1 may include power Q2.

[0231] S715: The fan operates at speed Q2.

[0232] Among them, the rotational speed Q2 is less than the rotational speed Q1.

[0233] S716: The power determination module sends a low-noise charging mode indication to the UI display module.

[0234] The low-noise charging mode indicator can be used to indicate that the electronic device 100 is currently being wirelessly charged at a power less than W1.

[0235] S717: In response to the low-power charging mode status indication, the UI display module can determine whether the display screen prompts the user that it is currently in low-noise charging mode.

[0236] For instructions on this step, please refer to S509.

[0237] S718: When the display screen does not indicate to the user that the user is in low-noise charging mode in the first prompt method, the UI display module displays low-noise charging prompt information and exit control in the second prompt method.

[0238] For instructions on this step, please refer to S510.

[0239] S719: The UI display module determines whether the first operation applied to the exit control has been detected.

[0240] For instructions on this step, please refer to S511.

[0241] S720: When the first operation is detected, in response to the first operation, the UI display module sends an exit command for the power determination module to exit the low-noise charging mode.

[0242] S721: In response to the command to exit low-power charging mode, the power determination module determines the power W1 and the speed Q1.

[0243] S722: The power determination module sends a data transmission command 2 to the data transmission module. The data transmission command 2 may include power W1 and speed Q1.

[0244] S723: The data transmission module encapsulates the power W1 and rotational speed Q1 into a second data packet.

[0245] S724: The data sending module sends a second data packet to the data receiving module.

[0246] The second data packet carries power W1 and rotational speed Q1.

[0247] S725: The data receiving module parses the power W1 and rotational speed Q1 from the second data packet.

[0252] The speed adjustment command 2 may include speed Q1.

[0253] S729: The fan operates at speed Q1.

[0254] In one possible implementation, when the power determination module determines that the power W2 is equal to the power W1, S705 and subsequent steps are executed at intervals of a specified duration T3 (e.g., 10 minutes or 15 minutes).

[0255] In one possible implementation, when the UI display module determines that the display screen has indicated to the user that it is in low-noise charging mode using a first prompt, the UI display module does not indicate to the user that it is in low-noise charging mode using a second prompt, but continues to display the first prompt. Then, the UI display module executes S719 and subsequent steps. Under the first prompt, the UI display module can receive and respond to the second operation (such as...). Figure 4C The touch operation shown, or as Figure 4E (As shown in the touch operation), switch to the second prompt mode and execute S718 to S729.

[0256] In one possible implementation, when the UI display module determines that no first operation has been detected acting on the exit control, it triggers the power determination module to execute S705 and subsequent steps at intervals of a specified duration T4 (e.g., 5 minutes, 3 minutes, etc.). The specified duration T4 is less than the specified duration T3.

[0257] Next, we will introduce another wireless charging method provided in the embodiments of this application.

[0258] Figure 9 This is a schematic diagram illustrating a specific implementation of another wireless charging method provided in this application.

[0259] like Figure 9 As shown, the specific implementation of this wireless charging method may include:

[0260] S901: When electronic device 100 approaches wireless charging device 200, wireless charging device 200 wirelessly charges electronic device 100 with power W1.

[0261] When the electronic device 100 is close to the wireless charging device 200, the electronic device 100 and the wireless charging device 200 can negotiate to wirelessly charge the electronic device 100 with power W1 and to dissipate heat from the electronic device 100 and / or the wireless charging device 200 with rotation speed Q1.

[0262] S902: The wireless charging device 200 determines the rotational speed Q1 corresponding to the power W1.

[0263] Specifically, the wireless charging device 200 can pre-store a mapping record 1, which can record the mapping relationship between one or more powers and one or more rotation speeds. After the electronic device 100 and the wireless charging device 200 agree to wirelessly charge the electronic device 100 with power W1, the wireless charging device 200 can determine the rotation speed Q1 corresponding to the power W1 based on the aforementioned mapping record 1.

[0264] S903: The wireless charging device 200 controls the fan to operate at a speed of Q1.

[0265] S904: Electronic device 100 detects the status of electronic device 100 and / or its environment.

[0266] This step can be referred to the description in S503 above.

[0267] S905: Electronic device 100 determines power W2 based on the state of electronic device 100 and / or its environment.

[0268] The electronic device 100 may pre-store a mapping record 2, which records the mapping relationship between the state and / or environment of the electronic device 100 and one or more specified power levels. The electronic device 100 can determine the power W2 corresponding to its state and / or environment from the mapping record 2.

[0269] Specifically, the implementation method of electronic device 100 detecting the state / environment of electronic device 100 through one or more devices, and determining the power W2 based on the state / environment of electronic device 100, will be described in detail in subsequent embodiments, and will not be repeated here.

[0270] S906: Electronic device 100 determines whether power W2 is less than power W1.

[0271] S907: When the power W2 is less than the power W1, the electronic device 100 sends a first data packet to the wireless charging device 200. This first data packet may carry the power W2.

[0272] S908: In response to the received first data packet, the wireless charging device 200 wirelessly charges the electronic device 100 with power W2.

[0273] S909: Wireless charging device 200 determines the rotational speed Q2 corresponding to power W2.

[0274] Specifically, the wireless charging device 200 can determine the rotation speed Q2 corresponding to the power W2 based on the mapping record 1.

[0275] S910: The wireless charging device 200 controls the fan to operate at a speed of Q2.

[0276] Among them, the rotational speed Q2 is less than the rotational speed Q1.

[0277] S911: Electronic device 100 determines whether the display screen prompts the user that it is currently in low-noise charging mode.

[0278] This step can be referred to in the description of S509.

[0279] S912: When the display screen does not indicate to the user that the device is currently in low-noise charging mode in the first manner, the electronic device 100 displays a low-noise charging prompt message and an exit control in the second manner. The exit control is used to exit the low-noise charging mode.

[0280] This step can be referred to in the description of S510.

[0281] S913: Electronic device 100 determines whether a first operation acting on the exit control has been detected.

[0282] S914: When the first operation is detected, in response to the first operation, the electronic device 100 sends a second data packet to the wireless charging device 200. The second data packet carries power W1.

[0283] S915: In response to the received second data packet, the wireless charging device 200 wirelessly charges the electronic device 100 with power W1.

[0284] S916: Wireless charging device 200 determines the rotational speed Q1 corresponding to power W1.

[0285] Specifically, the wireless charging device 200 can determine the rotation speed Q1 corresponding to the power W1 based on the mapping record 1.

[0286] S917: Wireless charging device 200 controls the fan to operate at speed Q1.

[0287] S911 to S917 are optional steps.

[0288] In one possible implementation, when the electronic device 100 determines that the power W2 is equal to the power W1, the electronic device 100 starts execution from step S904 at intervals of a specified duration T3 (e.g., 10 minutes or 15 minutes).

[0289] In one possible implementation, when the electronic device 100 determines that the display screen indicates to the user that it is currently in low-noise charging mode in a first prompt mode, the electronic device 100 does not indicate to the user that it is currently in low-noise charging mode in a second prompt mode, but continues to maintain the display in the first prompt mode. Then, the electronic device 100 executes S913 to S917. In the first prompt mode, the electronic device 100 can receive and respond to the second operation (such as...). Figure 4C The touch operation shown, or as Figure 4E (As shown in the touch operation), switch to the second prompt mode and execute S912 to S917.

[0290] In one possible implementation, when the electronic device 100 determines that no first operation acting on the exit control has been detected, the electronic device 100 starts execution from step S904 at intervals of a specified duration T4 (e.g., 5 minutes, 3 minutes, etc.). The specified duration T4 can be less than the specified duration T3.

[0291] Figure 10 This is a schematic diagram of the device architecture of another wireless charging system 10 provided in an embodiment of this application.

[0292] like Figure 10 As shown, the device architecture of the wireless charging system 10 may include: an electronic device 100 and a wireless charging device 200.

[0293] I. Electronic equipment 100

[0294] The electronic device 100 may include a processor, a charging management module, and a device module. The processor may include: a data transmission module, a power determination module, a device information reading module, a UI display module, and registers. Wherein:

[0295] For descriptions of the device module and device information reading module, please refer to the aforementioned documentation. Figure 6 The relevant description in the document.

[0296] The power determination module can be used to read the value of the register and determine the power W2 of the wireless charging device 200 based on the value of the register. Alternatively, the power determination module can determine the power W1 of the wireless charging device 200 in response to a received first operation.

[0297] Then, the power determination module can control the data transmission module to send data packets (e.g., the aforementioned first data packet, second data packet, etc.) to the wireless charging device 200. The data packets can carry a specified power (e.g., the aforementioned power W1, power W2, etc.).

[0298] The UI display module can be used to prompt the user that the device is currently in low-noise charging mode using a first prompt method and a second prompt method, determine whether the display screen prompts the user that the device is currently in low-noise charging mode using the first prompt method, and whether the first operation has been received. When the UI display module receives the first operation, it can control the power determination module to determine the power W1 of the wireless charging device 200.

[0299] The charging management module can be used to coordinate with the wireless charging device 200 to wirelessly charge the electronic device 100.

[0300] II. Wireless charging device 200

[0301] The wireless charging device 200 may include a controller, a wireless charging module, and a fan. The controller may include a data receiving module and a speed determination module. Wherein:

[0302] The wireless charging module can wirelessly charge the electronic device 100 based on a specified power (e.g., power W1, power W2, etc.).

[0303] The speed determination module can determine the specified speed of the fan based on the specified power.

[0304] The data receiving module can receive data packets sent by the electronic device 100 and parse out the specified power carried in the data packets. Then, the data receiving module can control the wireless charging module to wirelessly charge the electronic device 100 based on the specified power. Simultaneously, the data receiving module can send the specified power to the speed determination module, so that the speed determination module can determine the specified fan speed.

[0305] The speed determination module can control the fan to operate at a specified speed for heat dissipation of the wireless charging device 200 and the electronic device 100.

[0306] Figure 11 This is a schematic diagram of the module interaction process of another wireless charging method provided in an embodiment of this application.

[0307] like Figure 11 As shown, the module interaction process of this wireless charging method may include:

[0308] S1101: When the electronic device 100 and the wireless charging device 200 are close to each other, the charging management module of the electronic device 100 can work together with the wireless charging module of the wireless charging device 200 to wirelessly charge the electronic device 100 with a power of W1.

[0309] For an explanation of this step, please refer to the description in S901 above.

[0310] S1102: The speed determination module determines the speed Q1 corresponding to the power W1.

[0311] For an explanation of this step, please refer to the description of S902 above.

[0312] For example, mapping record 1 can be as shown in Table 3 below:

[0313] Table 3

[0314]

[0315]

[0316] The full-speed wireless charging mode has a power of 80W and a fan speed of 3600 RPM; the low-noise wireless charging mode has a power of 30W and a fan speed of 2000 RPM; the super noise-reducing charging mode has a power of 15W and a fan speed of 1000 RPM; and the silent wireless charging mode has a power of 5W and a fan speed of 0 RPM.

[0317] It should be noted that Table 3 is only used as an example to explain this application.

[0318] It is understandable that full-speed wireless charging means that the wireless charging device 200 can support the maximum power to wirelessly charge the electronic device 100, and the corresponding fan speed is also the maximum fan speed.

[0319] S1103: The speed determination module controls the fan to operate at speed Q1.

[0320] S1104: The device information reading module receives status indication information of one or more devices sent by the device module every specified period T1.

[0321] This step can be referred to in the description of S703.

[0322] S1105: The device information reading module assigns values ​​to registers based on the status indication information of one or more devices.

[0323] This step can be referred to in the description of S704.

[0324] S1106: The power determination module can read the value of the register from the register.

[0325] Reading the value of the register means reading the value of 4 binary bits in the register.

[0326] S1107: The power determination module determines the power W2 corresponding to the value in the register.

[0327] Understandably, the power determination module can determine the power W2 corresponding to the register value from the mapping record 2. The value of the four binary bits of the register is used to indicate the state and / or environment of the electronic device 100. The mapping record 2 can specifically record the mapping relationship between the register value and its corresponding specified power. That is, the mapping record 2 records the mapping relationship between the state and / or environment of the electronic device 100 and one or more specified powers.

[0328] In one possible implementation, the power determination module can read the register value N times (N>=2, preferably 6), take the average or median value, and then determine the power corresponding to the register value from the mapping record 2; in another possible implementation, the power determination module can read the current register value only once, and determine the power corresponding to the register value from the mapping record 2 based on the currently read register value.

[0329] For example, mapping record 2 can be as shown in Table 4:

[0330] Table 4

[0331] Register value Specified power Register value Specified power 0x0:reg[3:0]=0000 5W 0x8:reg[3:0] = 1000 15W 0x1:reg[3:0]=0001 80W 0x9:reg[3:0] = 1001 80W 0x2:reg[3:0] = 0010 80W 0xA:reg[3:0] = 1010 80W 0x3:reg[3:0]=0011 80W 0xB:reg[3:0] = 1011 80W 0x4:reg[3:0]=0100 30W 0xC:reg[3:0] = 1100 30W 0x5:reg[3:0]=0101 80W 0xD:reg[3:0] = 1001 80W 0x6:reg[3:0] = 0110 80W 0xE:reg[3:0]=1110 80W 0x7:reg[3:0]=0111 80W 0xF:reg[3:0]=1111 80W

[0332] As can be seen from Table 4, when the register value is 0000, the corresponding power is 5W; when the register value is 0100, the corresponding power is 30W; when the register value is 1000, the corresponding power is 15W; and when the register value is 1100, the corresponding power is 3W.

[0333] Table 4 is for illustrative purposes only and does not constitute any limitation.

[0334] S1108: The power determination module determines whether the power W2 is less than the power W1.

[0335] S1109: When the power W2 is less than the power W1, the power determination module sends a data transmission command 1 to the data transmission module. The data transmission command 1 may include the power W2.

[0336] S1110: The data transmission module encapsulates the power W2 into a first data packet.

[0337] S1111: The data sending module sends the first data packet to the data receiving module.

[0338] The first data packet carries power W2.

[0339] S1112: The data receiving module parses the power W2 from the first data packet.

[0340] S1113: The data receiving module sends a power adjustment command 1 to the wireless charging module.

[0341] The power adjustment command 1 may include power W2.

[0342] S1114: The wireless charging module and the charging management module wirelessly charge the electronic device 100 with power W2.

[0343] S1115: The data receiving module sends speed adjustment command 1 to the speed determination module.

[0344] The speed adjustment command 1 may include power W2.

[0345] S1116: The speed determination module determines the speed Q2 corresponding to the power W2.

[0346] S1117: The speed determination module controls the fan to operate at speed Q2.

[0347] Among them, the rotational speed Q2 is less than the rotational speed Q1.

[0348] S1118: The power determination module sends a low-noise charging mode indication to the UI display module.

[0349] The low-noise charging mode indicator can be used to indicate that the electronic device 100 is currently being wirelessly charged at a power less than W1.

[0350] S1119: In response to the low-power charging mode status indication, the UI display module can determine whether the display screen prompts the user that it is currently in low-noise charging mode in the first prompt manner.

[0351] For instructions on this step, please refer to S911.

[0352] S1120: When the display screen does not indicate to the user that the user is currently in low-noise charging mode in the first prompt method, the UI display module displays low-noise charging prompt information and exit control in the second prompt method.

[0353] For instructions on this step, please refer to S912.
