[0035] The first part describes the software and hardware operating environment of the technical solution disclosed in this application.

[0036] As shown in the figure, Figure 1 A schematic diagram of the structure of electronic device 100 is shown.

[0037] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 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.

[0038] Processor 110 may include one or more processing units, such as application processors (APs), modem processors, graphics processing units (GPUs), image signal processors (ISPs), controllers, video codecs, digital signal processors (DSPs), baseband processors, and / or neural network processors (NPUs). Different processing units may be independent components or integrated into one or more processors. In some embodiments, electronic device 101 may also include one or more processors 110. The controller can generate operation control signals based on instruction opcodes and timing signals to control instruction fetching and execution. In other embodiments, processor 110 may also include a memory for storing instructions and data. For example, the memory in processor 110 may be a cache memory. This memory can store instructions or data that processor 110 has just used or is repeatedly used. If processor 110 needs to reuse the instruction or data, it can directly retrieve it from the memory. This avoids repeated access, reduces the waiting time of processor 110, and thus improves the efficiency of electronic device 101 in processing data or executing instructions.

[0039] In some embodiments, the processor 110 may include one or more interfaces. These interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a SIM card interface, and / or a USB interface, etc. The USB interface 130 is a USB standard-compliant interface, specifically a Mini USB interface, a Micro USB interface, a USB Type-C interface, etc. The USB interface 130 can be used to connect a charger to charge the electronic device 101, and can also be used for data transfer between the electronic device 101 and peripheral devices. The USB interface 130 can also be used to connect headphones for audio playback.

[0040] 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 electronic device 100. In other embodiments of this application, the electronic device 100 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0041] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 receives charging input from the wired charger via the USB interface 130. In some wireless charging embodiments, the charging management module 140 receives wireless charging input via the wireless charging coil of the electronic device 100. While charging the battery 142, the charging management module 140 can also supply power to the electronic device via the power management module 141.

[0042] The power management module 141 connects the battery 142, the charging management module 140, and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140, providing power to the processor 110, internal memory 121, external memory, display screen 194, camera 193, and wireless communication module 160. The power management module 141 can also monitor parameters such as battery capacity, battery cycle count, and battery health status (leakage current, impedance). In some other embodiments, the power management module 141 may be located within the processor 110. In other embodiments, the power management module 141 and the charging management module 140 may be located in the same device.

[0043] The wireless communication function of electronic device 100 can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor, and baseband processor.

[0044] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 100 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with tuning switches.

[0045] The mobile communication module 150 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G / 6G, applied to the electronic device 100. The mobile communication module 150 may include at least one filter, switch, power amplifier, low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via antenna 1. In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0046] The wireless communication module 160 can provide solutions for wireless communication applications on the electronic device 100, including wireless local area networks (WLANs) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), and infrared (IR) technologies. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signals, and sends the processed signal to processor 110. The wireless communication module 160 can also receive signals to be transmitted from processor 110, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0047] Electronic device 100 implements display functions through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0048] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini light-emitting diode (miniled), a MicroLED, a Micro-OLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include one or more display screens 194.

[0049] Electronic device 100 can perform shooting functions through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0050] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0051] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the electronic device 100 may include one or more cameras 193.

[0052] Digital signal processors (DSPs) are used to process digital signals. Besides digital image signals, they can also process other digital signals. For example, when electronic device 100 selects a frequency, the DSP can perform Fourier transforms on the frequency energy.

[0053] Video codecs are used to compress or decompress digital video. Electronic device 100 may support one or more video codecs. Thus, electronic device 100 can play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG 2, MPEG 3, MPEG 4, etc.

[0054] An NPU (Neural Processing Unit) is a computational processor for neural networks (NNs). By borrowing the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, it can rapidly process input information and continuously learn on its own. NPUs enable intelligent cognitive applications in electronic devices, such as image recognition, facial recognition, speech recognition, and text understanding.

[0055] The external storage interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external storage interface 120 to perform data storage functions. For example, music, video, and other files can be saved on the external memory card.

[0056] Internal memory 121 can be used to store one or more computer programs, which include instructions. Processor 110 can execute the instructions stored in internal memory 121, thereby causing electronic device 101 to perform the methods for displaying page elements provided in some embodiments of this application, as well as various applications and data processing. Internal memory 121 may include a program storage area and a data storage area. The program storage area may store the operating system; the program storage area may also store one or more applications (such as a gallery, contacts, etc.). The data storage area may store data created during the use of electronic device 101 (such as photos, contacts, etc.). In addition, internal memory 121 may include high-speed random access memory, and may also include non-volatile memory, such as one or more disk storage components, flash memory components, universal flash storage (UFS), etc. In some embodiments, processor 110 can execute instructions stored in internal memory 121 and / or instructions stored in memory disposed in processor 110, thereby causing electronic device 101 to perform the methods for displaying page elements provided in embodiments of this application, as well as other applications and data processing. Electronic device 100 can implement audio functions such as music playback and recording through audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, and application processor.

[0057] The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, a barometric pressure sensor 180C, a magnetic sensor 180D, an accelerometer sensor 180E, a distance sensor 180F, a proximity light sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0058] The pressure sensor 180A is used to sense pressure signals and convert them into electrical signals. In some embodiments, the pressure sensor 180A can be disposed on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may include at least two parallel plates with conductive materials. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the pressure intensity based on the change in capacitance. When a touch operation is applied to the display screen 194, the electronic device 100 detects the touch operation intensity based on the pressure sensor 180A. The electronic device 100 can also calculate the touch position based on the detection signal from the pressure sensor 180A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example, when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS message is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS message is executed.

[0059] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 100. In some embodiments, the gyroscope sensor 180B can determine the angular velocity of the electronic device 100 around three axes (i.e., the X, Y, and Z axes). The gyroscope sensor 180B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the electronic device 100's shake, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shake of the electronic device 100 through reverse movement, thus achieving image stabilization. The gyroscope sensor 180B can also be used in navigation and motion-sensing game scenarios.

[0060] The 180E accelerometer can detect the magnitude of acceleration of electronic device 100 in various directions (typically three axes). When electronic device 100 is stationary, it can detect the magnitude and direction of gravity. It can also be used to identify the posture of electronic devices and applied to applications such as screen orientation switching and pedometers.

[0061] The ambient light sensor 180L is used to sense the brightness of ambient light. The electronic device 100 can adaptively adjust the brightness of the display screen 194 based on the sensed ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also work with the proximity sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

[0062] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can utilize the characteristics of the collected fingerprints to achieve fingerprint unlocking, accessing application locks, taking photos with fingerprints, answering calls with fingerprints, etc.

[0063] Temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 uses the temperature detected by temperature sensor 180J to execute a temperature handling strategy. For example, when the temperature reported by temperature sensor 180J exceeds a threshold, electronic device 100 performs thermal protection by reducing the performance of a processor located near temperature sensor 180J to reduce power consumption. In other embodiments, when the temperature is below another threshold, electronic device 100 heats battery 142 to prevent abnormal shutdown of electronic device 100 due to low temperature. In still other embodiments, when the temperature is below yet another threshold, electronic device 100 boosts the output voltage of battery 142 to prevent abnormal shutdown due to low temperature.

[0064] Touch sensor 180K, also known as a "touch panel," can be located on display screen 194. The touch sensor 180K and display screen 194 together form a touchscreen, also known as a "touch screen." Touch sensor 180K detects touch operations applied to or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through display screen 194. In other embodiments, touch sensor 180K may also be located on the surface of electronic device 100, in a different position than display screen 194.

[0065] For example, Figure 2 A software architecture block diagram of the electronic device 100 is shown. The layered architecture divides the software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application 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.

[0066] like Figure 2 As shown, the application layer can include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and SMS.

[0067] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0068] like Figure 2 As shown, the application framework layer may include a window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0069] The window manager is used to manage windowed applications. It can retrieve screen size, determine the presence of a status bar, lock the screen, and capture screenshots, among other things.

[0070] Content providers store and retrieve data, making that data accessible to applications. This data can include videos, images, audio, phone calls made and received, browsing history and bookmarks, phone books, and more.

[0071] A view system includes visual controls, such as controls for displaying text and controls for displaying images. View systems can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text notification icon could include views for displaying text and views for displaying images.

[0072] The phone manager is used to provide communication functions for electronic device 100. For example, it manages call status (including connection and disconnection).

[0073] The file explorer provides applications with various resources, such as localized strings, icons, images, layout files, video files, and more.

[0074] The notification manager allows applications to display notifications in the status bar. These notifications can be used to deliver informational messages and can disappear automatically after a short pause, requiring no user interaction. For example, the notification manager can be used to notify users of completed downloads or message alerts. The notification manager can also display notifications as icons or scrolling text in the top status bar, such as notifications from background applications, or as dialog boxes on the screen. Examples include displaying text messages in the status bar, emitting sounds, vibrating electronic devices, and flashing indicator lights.

[0075] The Android Runtime consists of core libraries and a virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0076] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0077] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0078] System libraries can include multiple functional modules. For example: surface manager, media libraries, 3D graphics processing libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), etc.

[0079] The Surface Manager is used to manage the display subsystem and provides the blending of 2D and 3D layers for multiple applications.

[0080] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0081] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0082] A 2D graphics engine is a graphics engine for 2D drawing.

[0083] The kernel layer is the layer between hardware and software. The kernel layer contains at least the display driver, camera driver, audio driver, and sensor driver.

[0084] The second part, the charging control method and apparatus disclosed in the embodiments of this application, is described below.

[0085] This application provides a reference. Figure 3A , Figure 3A This is a flowchart illustrating a charging control method provided in an embodiment of this application, applied to a charging device. The charging device includes a first UWB module and a radio frequency energy transmitting device. As shown in the figure, the charging control method includes:

[0086] 301. The target relative position parameters between the charging device and the electronic device are determined by the first UWB module and the second UWB module of the electronic device.

[0087] In this embodiment, the charging device may include a first UWB module, and the electronic device may include a second UWB module. The charging device can charge one or more electronic devices and can also act as a base station for UWB positioning. In this embodiment, the target relative position parameters may include at least one of the following: relative distance, relative angle, etc., which are not limited here. The relative angle can be a two-dimensional angle or a three-dimensional angle. Figure 3B As shown, a communication connection can be established between the charging device and the electronic device. When charging the electronic device, the charging device may or may not directly contact the electronic device.

[0088] In a specific implementation, the charging device can determine the target relative position parameters between the charging device and the electronic device through the first UWB module and the second UWB module of the electronic device. Specifically, the technologies used for positioning and ranging via UWB may include: two-way ranging (TWR) technology, Temporary Domestic Off-Site Assignment (TDOA) technology, Phase Difference of Arrival (PDOA) technology, etc., without limitation.

[0089] Furthermore, in this embodiment, the first UWB module may include two antennas: a first UWB antenna and a second UWB antenna. The electronic device may include a third UWB antenna. Please refer to [link to relevant documentation]. Figure 3C The first bevel angle of the first UWB antenna relative to the electronic device can be determined based on the UWB signal received by the first UWB antenna and the UWB signal received by the second UWB antenna and the UWB signal transmitted by the third UWB antenna. Specifically, the first distance difference between the arrival of the UWB signal at the first UWB antenna and the arrival at the second UWB antenna can be determined based on the UWB signal received by the first UWB antenna and the UWB signal received by the second UWB antenna. The first bevel angle of the first UWB antenna relative to the electronic device can be determined based on the first distance difference and the first interval distance between the first UWB antenna and the second UWB antenna.

[0090] Specifically, the first bevel angle of the first UWB antenna relative to the earphone case or mobile phone is determined based on the first distance difference and the first gap distance between the first UWB antenna and the second UWB antenna. The distance y between the earphone case or mobile phone and the line connecting the first UWB antenna of the first wireless earphone and the second UWB antenna of the second wireless earphone can be determined using the following formula:

[0091]

[0092] Among them, such as Figure 3C As shown, d is the first spacing distance between the first UWB antenna and the second UWB antenna, r is the first distance between the first UWB antenna and the electronic device, and p is the first distance difference (rp) between the distance the UWB signal travels to the first UWB antenna and the distance it travels to the second UWB antenna; furthermore, the first chamfer angle can be determined based on the distance y and r being the first distance between the first UWB antenna and the electronic device, where, as... Figure 3CAs shown, a right triangle can be constructed based on the distances y and r, where x is one leg of the right triangle, y is the other leg, the hypotenuse of the right triangle is the first distance r between the first UWB antenna and the electronic device, and the sine of the first tangent angle α is y / r.

[0093] 302. Determine the first operating parameters of the radio frequency energy transmitting device based on the target relative position parameters.

[0094] In this embodiment, the first operating parameter can be at least one of the following: the operating current of the radio frequency power transmitting device, the operating voltage of the radio frequency power transmitting device, the operating power of the radio frequency power transmitting device, the transmission power of the radio frequency power transmitting device, the signal transmission direction of the radio frequency power transmitting device, the number of charging objects of the radio frequency power transmitting device, the transmission frequency of the radio frequency power transmitting device, the transmission wavelength of the radio frequency power transmitting device, etc., which are not limited here. Different relative position parameters can correspond to different operating parameters of the radio frequency power transmitting device.

[0095] In one possible example, the target relative position parameters include target distance and target relative angle, and the first operating parameters include target transmission power and target signal transmission direction;

[0096] Step 302 above, determining the first operating parameters of the radio frequency energy transmitting device based on the target relative position parameters, may include the following steps:

[0097] 21. Determine the target transmission power corresponding to the target distance according to the preset mapping relationship between distance and transmission power;

[0098] 22. Determine the target signal transmission direction of the radio frequency energy transmitting device based on the target relative angle.

[0099] In this embodiment of the application, the electronic device can pre-store a preset mapping relationship between distance and transmission power. Then, the target transmission power corresponding to the target distance can be determined according to the mapping relationship, and the target signal transmission direction of the radio frequency energy transmitting device can be determined according to the target relative angle. The target signal transmission direction is from the transmitting antenna of the charging device to the receiving antenna of the electronic device. In this way, the corresponding transmission power can be set for the distance, and the transmission direction can be adjusted to point towards the electronic device to achieve the best charging effect.

[0100] 303. Control the radio frequency energy transmitting device to transmit a first energy signal according to the first operating parameters, the first energy signal being used to charge the electronic device.

[0101] The charging device can control the radio frequency energy transmitting device to operate according to the first operating parameters, so as to transmit a first energy signal, which is used to charge the electronic device.

[0102] In specific implementation, such as Figure 3D The charging device may include a controller module (MCU), a radio frequency (RF) power transmitter, and a UWB communication module (first UWB module). The first UWB module can be connected to two external antennas. The charging device may also include modules such as a control motor and a 360-degree rotating gimbal device, which are not limited here. The electronic device may be configured with a UWB communication module (second UWB module) and an energy receiver (wireless charging receiver module), wherein the wireless charging receiver module's receiving surface for the charging RF signal is located on the side of the electronic device. Furthermore, the charging device may also include an energy receiver for enabling other devices to charge the charging device. The electronic device may also include a radio frequency (RF) power transmitter for charging other devices.

[0103] In this embodiment, the MCU of the charging device can control the UWB communication module to establish a connection with the UWB communication module of the device to be charged and exchange ranging data. Finally, through the TWR algorithm and PDOA algorithm, the distance and angle information of the charging device relative to the charging device can be obtained in real time, achieving centimeter-level positioning accuracy. In addition, in this embodiment, the MCU can use the angle information between the charging device and the electronic device to calculate the specific number of motor steps and the direction of rotation required to align with the energy receiving device on the electronic device. Thus, the MCU controls the gimbal to rotate 360 ​​degrees of freedom, so that the antenna of the base station energy transmitting device can always cover the energy receiving position of the mobile phone, completing the wireless charging of the electronic device.

[0104] Secondly, in this embodiment, the MCU can dynamically adjust the transmission power of the radio frequency energy transmission device based on the real-time distance information between the charging device and the electronic device, thereby saving power consumption of the charging device while ensuring charging efficiency.

[0105] For example, in a specific implementation, the embodiments of this application can be carried out according to the following steps 1-6:

[0106] 1. Fix the location of the charging device, for example, it can be hung on the ceiling or attached to the wall;

[0107] 2. When the electronic device enters the range covered by the wireless charging device and begins wireless charging, the UWB module of the charging device is turned on and a probe frame of the UWB connection is sent to inquire whether the other party supports mobile charging. If a positive response of the UWB signal is received from the other electronic device, it means that the other electronic device supports the mobile charging function in this application, and proceed to step 3. Otherwise, the UWB charging module is turned off and wireless charging in normal mode is performed.

[0108] 3. The charging device first activates the UWB TWR ranging mode, through... Figure 3E The interaction shown in the frame allows the base station to calculate the distance between itself and the electronic device;

[0109] 4. After the charging device completes TWR ranging, the MCU controls the UWB to enter PDOA ranging mode and turns on the dual antennas of the UWB module (the specific activation method depends on the UWB chip specifications; it may be activated automatically by the UWB or by the MCU), and proceeds as follows: Figure 3F The interaction of the frame shown completes PDOA and calculates the angle between the base station and the electronic device at this time;

[0110] 5. Based on the distance information calculated in step 3, the transmission power of the base station's radio frequency signal is dynamically adjusted. Specifically, an empirical formula for optimal power / efficiency matching can be preset. The MCU dynamically calculates the optimal power value to be output based on this formula and the real-time distance information. Based on the angle information calculated in step 4, the MCU calculates the required rotation direction and angle of the gimbal based on the current position of the motor and the real-time measured angle information with the electronic device. This allows the MCU to deduce the output voltage, phase, and duration of the motor, control the rotation of the gimbal, and thus complete the real-time positioning and tracking of the electronic device. This ensures that the base station's radio frequency signal always covers the energy receiving device of the electronic device, thereby ensuring that wireless charging during movement is not interrupted.

[0111] 6. When the user stops wireless charging, or when the UWB heartbeat packet no longer receives a response from the electronic device within a preset time period, it indicates that the electronic device has left the wireless charging range or that the electronic device has turned off the UWB function. At this time, the MCU controls the UWB module to enter a sleep state and controls the gimbal to return to the initial position to reduce the power consumption of the charging device.

[0112] In one possible example, the following steps may also be included before step 301 above:

[0113] A1. Determine a first distance between the charging device and the electronic device;

[0114] A2. When the first distance is less than the first preset distance, a charging inquiry request is sent to the electronic device. The charging inquiry request is used to ask the electronic device whether to charge.

[0115] A3. Receive a charging confirmation response message sent by the electronic device, and execute the step of determining the target relative position parameters between the charging device and the electronic device through the first UWB module and the second UWB module of the electronic device.

[0116] In the specific implementation, the first preset distance can be set by the user or by the system default. The charging device can determine the first distance between the charging device and the electronic device through a designated module, which can be at least one of the following: Bluetooth module, Wi-Fi module, UWB module, etc., without limitation.

[0117] In specific implementation, the charging device can determine a first distance between the charging device and the electronic device. When the first distance is less than a first preset distance, the charging device sends a charging inquiry request to the electronic device. The charging inquiry request is used to ask the electronic device whether to charge. The charging device receives a confirmation charging response message sent by the electronic device and executes step 301. Otherwise, step 301 is not executed. That is, the charging device will only initiate a charging inquiry to remind the user to charge when the distance between the electronic device and the charging device is within a certain range.

[0118] In one possible example, step A1 above, determining the first distance between the charging device and the electronic device, may include the following steps:

[0119] A11. Obtain the signal strength change curve of the electronic device over a preset time period, wherein the horizontal axis of the signal strength change curve is time and the vertical axis is the signal strength value;

[0120] A12. Sample the signal intensity change curve to obtain multiple signal intensity values;

[0121] A13. Determine the target mean value based on the multiple signal strength values;

[0122] A14. Calculate the mean square error based on the multiple signal strength values ​​to obtain the target mean square error;

[0123] A15. Determine the target adjustment coefficient corresponding to the target mean square error according to the preset mapping relationship between the mean square error and the adjustment coefficient;

[0124] A16. Adjust the target mean value according to the target adjustment coefficient to obtain the first signal strength value of the electronic device;

[0125] A17. Determine the first distance corresponding to the first signal strength value according to the preset mapping relationship between the signal strength value and the distance.

[0126] The aforementioned preset time period can be pre-set or set by system default, and the preset time period can be a period of time prior to the current time. The charging device can also pre-store a preset mapping relationship between the mean square error and the adjustment coefficient.

[0127] In a specific implementation, the charging device can acquire the signal strength change curve of the electronic device detected by the charging device over a preset time period. The horizontal axis of the signal strength change curve is time, and the vertical axis is the signal strength value. The signal strength change curve is uniformly sampled to obtain multiple signal strength values. A target mean value is determined based on the multiple signal strength values. The mean square error is calculated based on the multiple signal strength values ​​to obtain the target mean square error. According to the preset mapping relationship between the mean square error and the adjustment coefficient, the target adjustment coefficient corresponding to the target mean square error is determined. The target mean value is adjusted based on the target adjustment coefficient to obtain the first signal strength of the second wireless earphone.

[0128] In this embodiment, the value range can be set by the user or updated automatically by the system. For example, the adjustment coefficient can range from -0.15 to 0.15. Furthermore, the charging device can adjust the target mean value according to the target adjustment coefficient to obtain the first signal strength value. The specific calculation method of the first signal strength value can refer to the following formula:

[0129] First signal strength value = (1 + target adjustment coefficient) * target mean value

[0130] Thus, the mean reflects the change of the signal over a period of time, while the standard deviation reflects the stability of the signal. This helps to accurately detect the signal strength of electronic devices. Furthermore, the electronic devices can also store a preset mapping relationship between signal strength values ​​and distances in advance, so that the first distance corresponding to the first signal strength value can be determined based on the mapping relationship.

[0131] In one possible example, before or after steps 301-303 above, the following steps may also be included:

[0132] When the second distance between the charging device and the electronic device is greater than the second preset distance, the electronic device is not charged. The second preset distance is greater than or equal to the first preset distance.

[0133] The second preset distance can be set by the user or be a system default. In practice, the charging device can determine the second distance between the charging device and the electronic device. If the second distance is greater than the second preset distance, the electronic device will not be charged. The second preset distance is greater than or equal to the first preset distance, thus ensuring the effectiveness of charging.

[0134] In one possible example, the following steps may also be included:

[0135] B1. Determine the number of target charging objects corresponding to the charging device, the target magnetic field interference intensity of the charging device, and the default prohibited charging distance;

[0136] B2. Determine the target first influence factor corresponding to the target magnetic field interference intensity according to the preset mapping relationship between the magnetic field interference intensity and the first influence factor;

[0137] B3. Determine the target second influence factor corresponding to the target number of charging objects according to the preset mapping relationship between the number of charging objects and the second influence factor;

[0138] B4. The second preset distance is obtained by calculating based on the first target influence factor, the second target influence factor, and the default prohibited charging distance.

[0139] In this embodiment, the charging device can determine the number of target charging objects corresponding to the charging device, the target magnetic field interference intensity of the charging device, and the default prohibited charging distance. The charging device can also pre-store a preset mapping relationship between magnetic field interference intensity and a first influence factor, and a preset mapping relationship between the number of charging objects and a second influence factor. Then, the charging device can determine the target first influence factor corresponding to the target magnetic field interference intensity according to the preset mapping relationship between the magnetic field interference intensity and the first influence factor. The value range of the first influence factor can be between -1 and 1, for example, -0.015 to 0.015. Next, it can also determine the target second influence factor corresponding to the target number of charging objects according to the preset mapping relationship between the number of charging objects and the second influence factor. The value range of the second influence factor is between 0 and 1; the more charging objects there are, the larger the second influence factor. Finally, a second preset distance can be obtained by calculating based on the target first influence factor, the target second influence factor, and the default prohibited charging distance. The specific calculation formula is as follows:

[0140] Second preset distance = Default charging prohibition distance = (1 + Target first influence factor) * (1 - Target second influence factor)

[0141] In this way, the default charging prohibition distance can be dynamically adjusted according to the number of objects being charged and the intensity of magnetic field interference, which can improve the charging efficiency of the charging device.

[0142] In one possible example, the charging device further includes a driving device; after step 303 above, the following steps may also be included:

[0143] C1. Obtain the target movement parameters of the electronic device;

[0144] C2. Determine the target position change parameters between the charging device and the electronic device;

[0145] C3. Determine the target adjustment parameter of the first working parameter based on the target position change parameter;

[0146] C4. Adjust the first working parameter according to the target adjustment parameter to obtain the second working parameter;

[0147] C5. Determine the target driving parameters of the driving device according to the preset target movement parameters;

[0148] C6. Control the driving device to work according to the target driving parameters, and control the radio frequency energy transmitting device to transmit a second energy signal with the second operating parameters. The second energy signal is used to charge the electronic device.

[0149] In this embodiment, the charging device can maintain communication with the electronic device, thereby acquiring the target movement parameters of the electronic device. These target movement parameters can be at least one of the following: movement speed, movement direction, movement angle, movement position, etc., without limitation. The driving device can be at least one of the following: gimbal, motor, etc., without limitation.

[0150] In specific implementation, the charging device can acquire the target movement parameters of the electronic device. Then, the charging device can determine the target position change parameters of the charging device and the electronic device. These target position change parameters represent the movement of the electronic device and can be at least one of the following: distance change parameters, angle change parameters, etc., without limitation. The charging device can also pre-store the mapping relationship between position change parameters and adjustment parameters. Then, based on this mapping relationship, the target adjustment parameter corresponding to the target position change parameter can be determined. Furthermore, according to the preset mapping relationship between movement parameters and drive parameters, the target drive parameter corresponding to the target movement parameter can be determined. Based on the target drive parameter, the drive device is controlled to operate, controlling the radio frequency energy transmitting device to transmit a second energy signal with a second operating parameter. The second energy signal is used to charge the electronic device. Thus, the operating parameters of the charging device can be adjusted accordingly based on the movement of the electronic device, ensuring charging stability and charging efficiency.

[0151] In this embodiment, the centimeter-level positioning accuracy of UWB technology is utilized. By equipping a high-degree-of-freedom gimbal base station device, it assists mobile phones and other electronic devices in wireless charging, solving the user pain point that mobile phones cannot move freely during wireless charging.

[0152] Furthermore, in this application, to save on the number of base stations, PDOA and TWR algorithms can be used. These algorithms require a UWB chip to support PDOA functionality, or two UWB chips can be used through hardware design to support PDOA. In this embodiment, the TDOA algorithm can also be used to achieve precise positioning of the electronic device's coordinates. Then, the coverage direction of the wireless charging transmitter module of the charging device is controlled based on the electronic device's coordinate information. This method requires four base stations to be deployed simultaneously in space, and the coordinate information of the base stations to be pre-set. When the electronic device enters the coverage area of ​​the base station, precise positioning of the electronic device can be achieved.

[0153] As can be seen, the charging control method described in this application embodiment is applied to a charging device, which includes a first UWB module and a radio frequency energy transmitting device. The target relative position parameters between the charging device and the electronic device are determined by the first UWB module and the second UWB module of the electronic device. The first operating parameters of the radio frequency energy transmitting device are determined based on the target relative position parameters. The radio frequency energy transmitting device is controlled to emit a first energy signal based on the first operating parameters. The first energy signal is used to charge the electronic device. In this way, the centimeter-level positioning accuracy of UWB technology can be used to accurately locate the electronic device, so as to determine the corresponding operating parameters of the radio frequency energy transmitting device to charge the electronic device, thereby improving the wireless charging efficiency.
