Description

Technical Field

[0001] This application relates to the field of wireless charging technology, and in particular to a method and apparatus for activating wireless charging. Background Technology

[0002] Currently, electronic devices such as mobile phones, tablets, laptops, smartwatches, electric toothbrushes, and Bluetooth headsets have become indispensable items in people's work and life. Batteries, because they can provide electrical energy storage for electronic devices and power other functional components of electronic devices through discharge, have become essential components in electronic devices. To avoid the wear and tear on components caused by frequent plugging and unplugging of charging cables during wired charging, as well as the inconvenience and safety hazards to users, wireless charging technology has emerged.

[0003] Typically, devices with charging capabilities (hereinafter referred to as "devices") always perform wireless charging detection by default. Devices can... Figure 1A The method shown is to send a Ping signal to send a signal and wake up the device to be charged, and to charge the device when a reply signal from the device that meets the conditions is received. In this scheme, the device needs to continuously send Ping signals, that is, even if there is no device to be charged in the vicinity of the device or such... Figure 1A As shown, even devices that do not require charging continue to send Ping signals, resulting in wasted power. This is especially true for electronic devices such as mobile phones, tablets, and laptops that can reverse charge other devices; using this solution leads to unnecessary power waste, rapid battery depletion, reduced battery life, and a poor user experience. Summary of the Invention

[0004] This application provides a wireless charging activation method and apparatus that can trigger wireless charging detection in a timely, accurate and reliable manner, reducing the power consumption of the device caused by unnecessary wireless charging detection.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, a method for enabling wireless charging is provided. This method can be applied to a device with wireless charging functionality, the device including a wireless charging sensing area. The method may include: detecting whether the device is being bumped; collecting data in response to the device being bumped; determining whether there is a device to be charged within the range of the wireless charging sensing area based on the data; if there is a device to be charged within the range of the wireless charging sensing area, initiating wireless charging detection; and if the wireless charging detection is successful, charging the device to be charged.

[0007] The solution provided in the first aspect above allows a device with wireless charging functionality to detect whether it has been bumped. When bumped, the device further determines whether there is a device to be charged within its wireless charging sensing area. If a device to be charged is confirmed within the sensing area, wireless charging detection is initiated, and the device is charged upon successful detection. Based on this, when a user brings a device requiring charging close to the device, the device can recognize this action through collision detection and further determine whether there is a device to be charged within its wireless charging sensing area. If a device to be charged is present, wireless charging detection is triggered, reducing the power consumption caused by unnecessary wireless charging detection.

[0008] For example, when a user needs to wirelessly charge a device through the device, they usually bring the device close to the device. This solution fully considers this characteristic in wired charging scenarios and identifies this possible action through collision detection. In addition, by collecting data, it further clarifies whether there is a device to be charged within the wireless charging sensing area of ​​the device, which can avoid false triggering of wireless charging detection caused by collisions between ordinary objects such as desktops and the device.

[0009] For example, when a user needs to wirelessly charge a device through the device, the user can also convey their need to the device by simply and conveniently "tapping" it while bringing the device close to the device. The device can recognize this user's need through collision detection. In addition, by collecting data, it can further clarify whether there is a device to be charged within the wireless charging sensing area of ​​the device, which can avoid false triggering of wireless charging detection caused by collisions between ordinary objects such as desktops and the device.

[0010] As an example, the device does not require additional hardware costs. It uses the device's existing first sensor to detect whether the device has been bumped. When a bump is detected, the device's existing second sensor collects data and determines whether the data meets preset characteristics. Based on the data, it determines whether there is a device to be charged within the wireless charging sensing area of ​​the device.

[0011] As an example, wireless charging detection includes sending a wake-up signal; successful charging detection includes receiving a response signal that meets the conditions. Exemplarily, the wake-up signal or response signal may include, but is not limited to, a Ping signal.

[0012] As an example, wireless charging detection includes: performing a Q-value scan; successful charging detection includes: the Q-value being greater than a reference Q-value.

[0013] As an example, wireless charging detection includes: performing a Q-value scan; if the Q-value is greater than a reference Q-value, sending a wake-up signal; successful charging detection includes: receiving a response signal that meets the conditions.

[0014] As an example, the above-mentioned device includes one or more of the following: a wireless charging dock, a wireless power bank, and an electronic device with wireless reverse charging capability.

[0015] As one possible implementation, before initiating wireless charging detection, the method further includes: acquiring environmental information of the device; determining, based on the environmental information, whether the device is in a first scene type and / or not in a second scene type; wherein, the first scene type includes one or more of a stationary scene and a handheld scene, and the second scene type includes one or more of a backpack scene and a pocket scene. If the device to be charged is present within the wireless charging sensing area, and the device is in the first scene type and / or not in the second scene type, wireless charging detection is initiated. In this way, the device can perform scene recognition based on collision detection and magnetic detection, and determine whether to trigger wireless charging detection based on the scene recognition result. This avoids unnecessary subsequent power consumption caused by performing wireless charging detection in scenarios with a high probability of false collisions, even when the user does not actually need wireless charging.

[0016] As an example, environmental information includes one or more of the following: ambient light information, environmental images, and motion information. This allows for accurate scene recognition using multiple types of environmental information.

[0017] As an example, the device can first perform collision detection and data acquisition, then determine whether there is a device to be charged within the wireless charging sensing area and perform scene recognition based on the data. When it is determined that the device is in a first scene type and / or not in a second scene type, wireless charging detection is initiated. In this way, unnecessary power consumption caused by accidental collisions between devices in a backpack / pocket and the acquisition of data that meets preset characteristics can be avoided in the first scene category, such as backpack scene or pocket scene.

[0018] As an example, the device can first perform scene recognition, and if it determines that it is in a first scene type and / or not in a second scene type, it will not perform collision detection and data collection. In this way, unnecessary power consumption caused by performing collision detection, data collection, and wireless charging detection can be avoided in the first scene category, such as backpack scene or pocket scene, where the user is unlikely to trigger wireless charging.

[0019] As an example, the device can identify the scene during collision detection or data acquisition, and stop collision detection or data acquisition when it determines that the scene is in a first scene type and / or not in a second scene type. This avoids unnecessary power consumption caused by performing collision detection, data acquisition, and wireless charging detection in first scene categories where the user is unlikely to trigger wireless charging, such as backpack or pocket scenarios.

[0020] As one possible implementation, the detection of whether the aforementioned device has been collided includes: detecting the acceleration value of the device; if the acceleration value meets a preset acceleration characteristic, it is determined that the device has been collided; if the acceleration value does not meet the preset acceleration characteristic, it is determined that the device has not been collided. In this way, it can fully consider the characteristic that when a user needs to wirelessly charge a device, they need to bring the device close to the device, and accurately identify the user's wireless charging needs by recognizing this possible action through collision detection.

[0021] As one possible implementation, the aforementioned data includes at least one of magnetic induction information, pressure information, and capacitance information. The determination of whether a device to be charged exists within the wireless charging sensing area based on the data includes: if one or more of the following conditions are met: the magnetic induction information meets a preset pressure characteristic, the pressure information meets a preset pressure characteristic, and the capacitance information meets a preset capacitance characteristic, then it is determined that a device to be charged exists within the wireless charging sensing area; if the magnetic induction information does not meet the preset pressure characteristic, the pressure information does not meet the preset pressure characteristic, and the capacitance information does not meet the preset capacitance characteristic, then it is determined that no device to be charged exists within the wireless charging sensing area. In this way, data acquisition can further clarify whether a device to be charged exists within the wireless charging sensing area of ​​the device, avoiding false triggering of wireless charging detection caused by slight collisions between ordinary objects such as desktops and the device.

[0022] In a second aspect, an apparatus is provided that has a wireless charging function. The apparatus includes: a first sensor for detecting whether the apparatus is bumped; a second sensor for collecting data when the apparatus is bumped, the data being used to determine whether there is a device to be charged within the wireless charging sensing area of ​​the apparatus; a memory for storing computer program instructions; and a controller for executing the computer program instructions to support the apparatus in implementing the method as described in any possible implementation of the first aspect.

[0023] As an example, the first sensor includes, but is not limited to, one or more of an accelerometer, a pressure sensor, etc.

[0024] As an example, the second sensor includes, but is not limited to, one or more of the following: a magnetic sensor, a pressure sensor, a capacitive sensor, etc.

[0025] As an example, the first sensor and the second sensor may be the same sensor. For instance, both the first sensor and the second sensor may be pressure sensors.

[0026] As an example, the device described above also includes a third sensor for acquiring environmental information about the device.

[0027] As an example, a third sensor may include, but is not limited to, one or more of an accelerometer, an ambient light sensor, a camera, etc.

[0028] As an example, the third sensor is the same sensor as the first and / or second sensor. For instance, the third sensor is a pressure sensor, as are the first and / or second sensors.

[0029] Thirdly, a computer-readable storage medium is provided that stores computer program instructions that, when executed by a processor, implement the method as described in any possible implementation of the first aspect.

[0030] Fourthly, a computer program product containing instructions is provided, which, when run on a computer, causes the computer to implement the method as described in any possible implementation of the first aspect.

[0031] Fifthly, a chip system is provided, comprising processing circuitry and a storage medium storing computer program instructions; when executed by the processor, the computer program instructions implement the method as described in any possible implementation of the first aspect. The chip system may be composed of chips or may include chips and other discrete devices. Attached Figure Description

[0053] The technical solutions of the embodiments of this application will be 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; "and / or" in this 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.

[0054] Hereinafter, the terms "first," "second," etc., are used only to distinguish different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in the embodiments of this application does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not constitute an unnecessary limitation due to the use of such prefixes.

[0055] Furthermore, in the embodiments of this application, "connection" can be a direct connection or an indirect connection; in addition, it can refer to an electrical connection or a communication connection; for example, the connection of two electrical components A and B can refer to A and B being directly connected, or it can refer to A and B being indirectly connected through other electrical components or connection media, or it can refer to A and B being indirectly connected through other communication devices or communication media, as long as it enables communication between A and B.

[0056] Taking wireless charging provided by the reverse charging function of an electronic device as an example, the electronic device is a device with wireless charging capability. To reduce unnecessary power consumption caused by the electronic device constantly sending Ping signals when the user does not need wireless charging, one possible approach is to set up a wireless charging detection function switch, such as a reverse charging detection function switch. When the user does not enable the wireless charging detection function, the electronic device does not send Ping signals. When the user manually enables the reverse charging detection function, the electronic device begins to send Ping signals to attempt to communicate with other devices. However, this solution requires the user to manually enable the reverse charging detection function, and the reverse charging detection function switch is often nested in the "Settings" menu, such as... Figure 1B As shown, the wireless reverse charging function is nested in the "Settings" interface → "Power Saving & Battery" interface → "More Battery Functions" interface → "Wireless Reverse Charging" interface, which is not easy to find and is cumbersome for users. In addition, users' unfamiliarity with the wireless reverse charging detection function will lead to low usage of the wireless reverse charging function.

[0057] To avoid the inconvenience caused to users by the cumbersome process of enabling the wireless reverse charging detection function, as another possible implementation method, such as Figure 2 As shown, electronic devices can first determine whether a device to be charged exists by detecting the Q value of the charging coil, and then, upon confirming the existence of a device to be charged (such as...),... Figure 2 The electronic pen (as shown) sends a Ping signal to attempt communication with the device to be charged. However, in this scheme, the electronic device needs to continuously detect the Q value. Although detecting the Q value can save some power compared to sending a Ping signal, it still introduces unnecessary power consumption. In addition, when there are objects that do not need to be charged in the magnetic field around the electronic device, such as metallic foreign objects, the conductivity and magnetism of the objects will also affect the equivalent inductance and / or equivalent resistance of the charging coil of the electronic device. The change in equivalent inductance and / or equivalent resistance can also be reflected in the Q value, causing unnecessary Ping signal transmission. Therefore, the power saving of the scheme that triggers wireless reverse charging detection by meeting the preset benchmark value of Q value is limited.

[0058] As another possible implementation, electronic devices can, when the user has a reverse charging need, [charge the device via...]. Figure 3 The magnetic components on the electronic device shown attract and hold the device to be charged (e.g., Figure 3 The electronic pen shown uses a pressure sensor to detect the pressure exerted by the device being charged after the magnetic component attracts it. When the pressure reaches a preset threshold, a Ping signal is sent to attempt communication with the device. However, in this solution, the wireless reverse charging detection relies on the magnetic component, requiring a pressure sensor at a specific location on the component, which is costly. Furthermore, it is not compatible with devices that do not have a magnetic component.

[0059] To automatically, timely, accurately, and reliably trigger wireless charging detection, this application provides a wireless charging activation method. This method takes into account the specific characteristics of wireless charging scenarios and accurately and reliably identifies the user's wireless charging needs through one or more detection methods, reducing the power consumption of the device caused by unnecessary wireless charging detection.

[0060] In some embodiments of this application, the device can use one or more first sensors, such as an accelerometer (ACC) or a pressure sensor, to detect whether the device is being collided. When a collision is detected, data is collected by one or more second sensors, such as a magnetic sensor (magnetometer), a pressure sensor, or a capacitance sensor, to determine whether the data meets preset characteristics, so as to determine whether there is a device to be charged within the wireless charging sensing area of ​​the device. When a device to be charged is detected within the wireless charging sensing area of ​​the device, the device starts wireless charging detection.

[0061] In some examples, the first sensor may be the same as the second sensor. For example, both the first and second sensors may be pressure sensors.

[0062] In some embodiments, when a user needs to wirelessly charge a device through the device, the user will usually bring the device close to the device. This application fully considers this characteristic in the wired charging scenario and identifies this possible action through collision detection. In addition, one or more sensors such as magnetic detection, pressure detection, and capacitance detection are used to further clarify whether there is a device to be charged within the wireless charging sensing area of ​​the device, which can avoid false triggering of wireless charging detection caused by collisions between ordinary objects such as desktops and the device.

[0063] In some embodiments, when a user needs to wirelessly charge a device through the device, they can communicate their needs to the device by simply and conveniently tapping it. The device can identify this possible action through collision detection. In addition, it can further clarify whether there is a device to be charged within the wireless charging sensing area of ​​the device by detecting one or more sensors such as magnetic detection, pressure detection, and capacitance detection, which can avoid false triggering of wireless charging detection caused by collisions between ordinary objects such as desktops and the device.

[0064] The combination of collision detection and sensor detection can reduce the false trigger rate of wireless charging detection, improve the accuracy and reliability of identifying users' wireless charging needs, and automatically, timely, accurately and reliably trigger wireless charging detection, thereby reducing the power consumption of the device caused by unnecessary wireless charging detection.

[0065] In some embodiments of this application, the device can perform scene recognition based on collision detection and sensor detection. When it is determined that the scene is in a first scene type and / or not in a second scene type, the device initiates wireless charging detection. For example, the first scene type may include, but is not limited to, one or more of the following: a stationary scene, a handheld scene, etc., and the second scene type may include, but is not limited to, one or more of the following: a backpack scene, a pocket scene, etc.

[0066] It's understandable that when the device is in scenarios like a backpack or pocket, collision detection is usually not user-triggered, resulting from free collisions between objects without the user's awareness. Data meeting preset characteristics is due to these free collisions. In these situations, the user has no wireless charging need. If the device were to perform wireless charging detection, it would cause unnecessary Ping signal transmissions, leading to unnecessary power consumption. However, when the device is in static or handheld scenarios, collision detection is usually user-triggered. Data meeting preset characteristics is typically due to conscious user actions. In these situations, the user is highly likely to have a wireless charging need. If the device were to perform wireless charging detection, it could promptly meet the user's wireless charging needs, improving the user experience. Therefore, by recognizing scenarios and determining whether to trigger wireless charging detection based on the scene recognition results, the device can further reduce the false trigger rate of wireless charging detection, improve the accuracy and reliability of recognizing user wireless charging needs, and thus further reduce the power consumption caused by unnecessary wireless charging detection.

[0067] In some embodiments of this application, the device can further determine whether there is a device to be charged within the wireless charging sensing area, based on collision detection and sensor detection. This can be achieved through one or more methods, such as Q-value scanning, near-field communication (NFC), or Bluetooth communication. When a device to be charged is found within the wireless charging sensing area, the device initiates wireless charging detection. This further reduces the false trigger rate of wireless charging detection, improves the accuracy and reliability of identifying user wireless charging needs, and thus further reduces the power consumption caused by unnecessary wireless charging detection.

[0068] As an example, the wireless charging activation method provided in this application embodiment can be applied to devices with wireless charging functionality, i.e., the "device" described in this application embodiment. Exemplarily, the "device" described in this application embodiment may include, but is not limited to, wireless charging docks, wireless power banks, electronic devices with wireless reverse charging functionality, etc.

[0069] As an example, a wireless charging dock can be placed in one or more scenarios, including but not limited to homes, shopping malls, supermarkets, office buildings, cinemas, train stations, airports, hotels, restaurants, and parking lots. This application is an embodiment and does not limit the carrier of the wireless charging dock; for example, the wireless charging dock may be set up independently or on other carriers such as vehicles or airplanes.

[0070] As an example, a wireless charging dock may include, but is not limited to, one or more types such as a desktop wireless dock or a car wireless dock.

[0071] As an example, electronic devices with wireless reverse charging capabilities may include, but are not limited to, smartphones, netbooks, tablets, smart drawing tablets, handwriting tablets, smartwatches, smart bracelets, phone watches, smart glasses, smart cameras, PDAs, smart robots, personal computers (PCs), personal digital assistants (PDAs), portable multimedia players (PMPs), augmented reality (AR) / virtual reality (VR) devices, projection devices, or motion-sensing game consoles in human-computer interaction scenarios, without limitation.

[0072] As an example, please refer to Figures 4A-4C , Figures 4A-4C Examples of several wireless charging scenarios provided in the embodiments of this application are shown, wherein Figure 4A This demonstrates how to communicate with wearable devices via mobile phone. Figure 4A (Using a smartwatch as an example) An example of a reverse charging scenario. Figure 4B This demonstrates the use of a wireless charging dock to charge electronic devices ( Figure 4B Examples of reverse charging scenarios (using mobile phones, wireless earphones, etc. as examples). Figure 4C This demonstrates how to wirelessly charge electronic devices (using a power bank). Figure 4C (Using a mobile phone as an example) Example of a reverse charging scenario.

[0073] Figures 4A-4C As examples of several possible wireless charging scenarios, the embodiments of this application do not limit the device type, structure and function of the device and the device to be charged.

[0074] As an example, please refer to Figures 5A-5C , Figures 5A-5C Taking an electronic device with wireless reverse charging function, a wireless power bank, and a wireless charging dock as examples, the hardware structure diagrams of the three devices provided in the embodiments of this application are shown.

[0075] Taking an electronic device with wireless reverse charging capability as an example, such as Figure 5A As shown, the device may include a battery 501, a direct current-to-direct current (DC-DC) converter 502, a transceiver-receiver (TRX) chip 503, a TRX coil 504, an MCU 505, a sensor module 506, and a user interaction module 507.

[0076] Taking a wireless charging bank as an example, such as Figure 5B As shown, the device may include a battery 501, a DC-DC converter 502, a TRX chip 503, a TRX coil 504, an MCU 505, and a sensor module 506.

[0077] Taking the device as a wireless charging dock as an example, such as Figure 5C As shown, the device may include a power interface 508, a DC-DC converter 502, a transmitter (TX) chip 509, a TX coil 510, an MCU 505, and a sensor module 506.

[0078] Among them, the battery 501 serves as an energy storage unit, capable of receiving and storing electrical energy transmitted through a wireless charging coil (such as a TRX coil 504) and / or a wired charging interface, providing power support for the device, such as powering one or more modules such as a DC-DC converter 502, a TRX chip 503, an MCU 504, a TRX coil 504, a sensor module 506, or a user interaction module 507, to maintain the normal operation of the device.

[0079] In this embodiment, the battery 501 can also be used to wirelessly charge the device by coupling it with the charging coil of the device to be charged via the TRX coil 504.

[0080] The DC-DC converter 502 can be used to convert one DC voltage to another, such as boosting or bucking the input voltage, to ensure stable output voltage and meet the specific power requirements of different devices or circuits, thereby improving the efficiency and stability of charging and / or discharging.

[0081] As an example, a DC-DC converter can achieve voltage conversion through a switching circuit. For example, a DC-DC converter can include one or more power switching transistors (such as MOSFETs), as well as energy storage components such as inductors and capacitors. By controlling the on and off times of the switching transistors, the storage and release of energy in the inductor can be adjusted, thereby converting the input DC voltage into the required output DC voltage.

[0082] As an example, a DC-DC converter may include, but is not limited to, a buck DC-DC converter, a boost DC-DC converter, a buck-boost DC-DC converter, etc.

[0083] The TRX chip 503, acting as both a transmitter and receiver chip, handles signal transmission and reception during wireless charging. For example, when the TRX chip 503 is used as a receiver, it demodulates and decodes the high-frequency signal received from the charging device, converting it into recognizable charging control and data signals. It also sends charging status information back to the charging device, enabling bidirectional communication and control during the charging process. Conversely, when the TRX chip 503 is used as a transmitter to wirelessly charge other devices, it receives charging status feedback from the device being charged, allowing it to control the wireless charging process.

[0084] As an example, the TRX chip 503 may include an inverter bridge that converts direct current from the DC-DC converter 502 into alternating current to meet the energy transfer and signal processing requirements during wireless charging.

[0085] The introduction to the TX chip 509 is similar to that of the TRX chip 503 as a transmitter chip; please refer to the introduction of the TRX chip 503 above.

[0086] The MCU 504 can be used to coordinate the operation of various modules in the device. For example, the MCU 504 can communicate with the DC-DC converter 502, TRX chip 503, MCU 505, sensor module 506, and user interaction module 507 to monitor charging status, battery level, temperature, and other information in real time. According to preset algorithms and strategies, it can control the operating mode of the DC-DC converter 502 to adjust the charging current and voltage, and take corresponding protection measures in case of abnormal conditions, such as overvoltage protection, overcurrent protection, and overheat protection, to ensure the safety and stability of the wireless charging process.

[0087] The TRX coil 504, serving as both a wireless transmitting and receiving coil, is a key component in a wireless charging system. In some embodiments, the TRX coil 504 functions as a wireless receiving coil, converting the alternating magnetic field generated by the transmitting coil at the charging end into an alternating current through electromagnetic induction, thereby inducing an electromotive force in the circuit and providing power input for subsequent charging circuits. In some embodiments, the TRX coil 504 functions as a wireless transmitting coil, emitting a magnetic field during charging and coupling magnetically with the receiving coil at the charging end to achieve wireless energy transfer.

[0088] As an example, the device may include multiple TRX coils 504. The multiple TRX coils 504 may be arranged in a planar manner, such as multiple TRX coils 504 being laid flat without overlapping each other, or the multiple TRX coils 504 may be arranged in a vertical manner, such as at least two of the multiple TRX coils 504 overlapping each other.

[0089] The description of the TX coil 510 is similar to that of the TRX coil 504 as a wireless transmitting coil; please refer to the description of the TRX coil 504 above.

[0090] Sensor module 506 includes an accelerometer and one or more of the following sensors: a magnetic sensor, a pressure sensor, a capacitive sensor, etc.

[0091] The accelerometer is used to detect whether the device has been collided with. As an example, the accelerometer can be used to detect the acceleration values ​​of the device, such as the acceleration values ​​in multiple directions (typically three axes). For instance, if the accelerometer detects a three-axis acceleration value of 0, it can be determined that the device has not been collided with; if the accelerometer detects an acceleration value on at least one axis that is not 0 and meets preset acceleration characteristics, it can be determined that the device has been collided with.

[0092] As an example, accelerometers can follow various physical principles. For instance, accelerometers can utilize microelectromechanical systems (MEMS). When the device generates acceleration, the mass will displace under inertia. By detecting this displacement and converting it into an electrical signal, the acceleration value can be measured, and the measured value can be converted into a standard analog current signal or digital signal output. The embodiments of this application do not limit the working principle of accelerometers.

[0093] As an example, an acceleration sensor may include, but is not limited to, an accelerometer (ACC).

[0094] A magnetic sensor is used to detect whether there is a magnetically inductive object within the wireless charging sensing area of ​​the device. As an example, the magnetic sensor can be used to collect magnetic induction information. For instance, if the magnetic sensor does not collect magnetic induction information that meets preset magnetic characteristics, it can be determined that there is no magnetically inductive object within the wireless charging sensing area of ​​the device; if the magnetic sensor collects magnetic induction information that meets preset magnetic characteristics, it can be determined that there is a magnetically inductive object within the wireless charging sensing area of ​​the device, such as the device to be charged.

[0095] As an example, magnetic sensors may include, but are not limited to, magnetometers.

[0096] A pressure sensor is used to detect whether an object is applying pressure to the device within the wireless charging sensing area. As an example, the pressure sensor can be used to collect pressure information. For instance, if the pressure sensor does not collect pressure information that meets preset pressure characteristics, it can be determined that no object is applying pressure to the device within the wireless charging sensing area; if the pressure sensor collects pressure information that meets preset pressure characteristics, it can be determined that an object, such as a device to be charged, is applying pressure to the device within the wireless charging sensing area.

[0097] Capacitive sensors are used to detect whether there are objects affecting the capacitance within the wireless charging sensing area of ​​a device. As an example, a capacitive sensor can be used to collect capacitance information. For instance, if the capacitive sensor does not collect capacitance information that meets preset capacitance characteristics, it can be determined that there are objects affecting the capacitance within the wireless charging sensing area of ​​the device; if the capacitive sensor collects capacitance information that meets preset capacitance characteristics, it can be determined that there are objects affecting the capacitance within the wireless charging sensing area of ​​the device, such as a device to be charged.

[0098] In some embodiments of this application, the sensor module 506 may also include, but is not limited to, one or more of the following: a temperature sensor, a voltage sensor, and a current sensor. The temperature sensor is used to monitor the temperature of critical components such as the battery and coil during wired or wireless charging to prevent overheating from damaging the equipment or causing safety hazards. The voltage and current sensors detect the charging voltage and current in real time, providing accurate data to the MCU 504 so that the MCU 504 can precisely control the charging process according to the battery's charging state and the device's requirements, achieving the switching between different charging stages such as constant current charging and constant voltage charging.

[0099] The user interaction module 507 can be used to display relevant information about wireless charging to the user, such as charging status indicators (e.g., charging in progress, charging complete, charging error, etc.) and battery level display. It may also provide some user operation interfaces, such as start / stop charging buttons and charging mode switching buttons, so that the user can intuitively understand the charging status and control the charging process to a certain extent.

[0100] As an example, the user interaction module 507 may include, but is not limited to, one or more of the following: a display screen, a breathing light, an audio component, a buzzer, etc.

[0101] The power interface 508 can be used to connect the wireless charging dock to an external power adapter, providing power input to the wireless charging dock. For example, one end of the power adapter can be plugged into an AC outlet, and the other end can be connected to the wireless charging dock via the power interface 508, enabling the wireless charging dock to obtain power and then wirelessly charge the device placed on the wireless charging dock.

[0102] As an example, the power interface 508 may include, but is not limited to, Type-C interface, Type-B interface, etc.

[0103] This application Figures 5A-5C The illustrated structure does not constitute a specific limitation on the device. In other embodiments of this application, the device 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.

[0104] For example, in some embodiments, Figure 5B The TRX chip 503 shown can be replaced with a TX chip, and the TRX coil 504 can be replaced with a TX coil. That is, the wireless power bank may have the function of wirelessly charging other devices, but it does not have the function of receiving wireless charging.

[0105] As an example, please refer to Figure 6 , Figure 6 A hardware structure diagram of a charging device provided in an embodiment of this application is shown.

[0106] like Figure 6 As shown, the device to be charged may include a battery 601, a DC-DC converter 602, a receiver (RX) chip 603, an RX coil 604, and an MCU 605. As an example, the RX chip 603 may include a rectifier bridge and a low dropout regulator (LDO).

[0107] The rectifier bridge is used to rectify and process the alternating current, converting it into direct current to provide a suitable power supply for the RX chip 603, thus enabling wireless charging by converting energy from AC to DC. The LDO is used to adjust the conduction level of its internal transistors to convert the unstable DC voltage after rectification into a stable voltage value suitable for the operation of the RX chip 603's internal circuitry. In some embodiments, the LDO can also be used to reduce high-frequency noise and ripple on the power line, improve the RX chip 603's anti-interference capability, and ensure data transmission stability and charging efficiency during wireless charging.

[0109] This application Figure 6 The illustrated structure does not constitute a specific limitation on the device to be charged. In other embodiments of this application, the device to be charged 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.

[0110] For example, in some embodiments, Figure 6 The device to be charged shown may also include a user interaction module, which is used to display relevant information about wireless charging to the user, such as charging status indication and battery level display. It may also provide some user operation interfaces, such as start / stop charging buttons and charging mode switching buttons, so that the user can intuitively understand the charging status and control the charging process.

[0111] For example, in some embodiments, Figure 6 The RX chip 603 shown can be replaced with a TRX chip, and the RX coil 604 can be replaced with a TRX coil. That is, the device to be charged not only has the function of receiving wireless charging, but also has the function of wirelessly charging other devices.

[0112] This application aims to accurately and reliably identify a user's wireless charging needs when the user has a wireless charging request, based on the specific characteristics of wireless charging scenarios, through one or more detection methods, thereby reducing the power consumption of the device caused by unnecessary wireless charging detection.

[0113] The following will take an electronic device with wireless reverse charging function as an example, and describe in detail the wireless charging activation method provided in this application embodiment with specific embodiments. For other types of devices such as wireless charging docks or wireless power banks, the following specific implementation process can also be referred to.

[0114] In some embodiments, the device can detect whether the device is being collided by an acceleration sensor. When the device is collided, a magnetic sensor can detect whether there is a device with magnetic induction capability within the wireless charging sensing area of ​​the device. When a device with magnetic induction capability is detected within the wireless charging sensing area of ​​the device, the device initiates wireless charging detection, such as performing wireless reverse charging detection.

[0115] As an example, please refer to Figure 7A , Figure 7A A flowchart of a wireless charging activation method provided in an embodiment of this application is shown.

[0116] like Figure 7A As shown, the wireless charging activation process may include S701-S705:

[0117] S701, The device detected a collision.

[0118] As one possible implementation, the device can detect whether it has been collided with a first sensor. For example, the first sensor may include an accelerometer, and the device can detect the acceleration value of the device, such as by an accelerometer, including but not limited to an accelerometer, such as detecting the acceleration value of the device in multiple directions (generally three axes), and determine whether the device has been collided with based on the detected acceleration values ​​in multiple directions.

[0119] In some embodiments, if the detected acceleration values ​​in multiple directions match a preset acceleration characteristic, the device can determine that a collision has occurred.

[0120] As an example, the preset acceleration characteristics may be determined and set in the device in advance through experiments. The experiments include collision tests with various types, brands and models of devices to be charged. Through the experiments, a relatively accurate judgment threshold can be obtained, thereby improving the accuracy of the device collision detection results.

[0121] As an example, the preset acceleration characteristics include, but are not limited to, one or more of the preset acceleration change values ​​and preset acceleration change rates, etc.

[0122] S702, In response to being collided, the device collects data.

[0123] As one possible implementation, the device includes a second sensor, which can collect data in response to the device being bumped.

[0124] As an example, the second sensor may include one or more of the following: a magnetic sensor, a pressure sensor, a capacitive sensor, etc.

[0125] For example, a magnetic sensor can be used to collect magnetic induction information; for instance, a magnetic sensor may include, but is not limited to, a magnetometer. A pressure sensor can be used to detect pressure information. A capacitance sensor can be used to detect capacitance information. By collecting one or more types of data, such as magnetic induction information, pressure information, and capacitance information, it is possible to accurately and quickly determine whether there is a device to be charged within the wireless charging sensing area of ​​the device.

[0126] S703: The device determines whether there is a device to be charged within the wireless charging sensing area based on the data.

[0127] As one possible implementation, the device can determine whether there is a device to be charged within its wireless charging sensing area based on whether the data meets preset characteristics.

[0128] In some embodiments, if one or more of the following conditions are met: the device acquires magnetic induction information that meets preset magnetic force characteristics through a magnetic sensor, acquires pressure information that meets preset pressure characteristics through a pressure sensor, acquires capacitance information that meets preset capacitance characteristics through a capacitance sensor, etc., the device can determine that there is a device to be charged within the wireless charging sensing area of ​​the device; if the device does not acquire magnetic induction information that meets preset magnetic force characteristics through a magnetic sensor, does not acquire pressure information that meets preset pressure characteristics through a pressure sensor, and does not acquire capacitance information that meets preset capacitance characteristics through a capacitance sensor, the device can determine that there is no device to be charged within the wireless charging sensing area.

[0129] As an example, preset magnetic characteristics, preset pressure characteristics, or preset capacitance characteristics may be pre-determined and set in the device through experiments. The experiments include placing various types, brands, and models of devices to be charged within the wireless charging sensing area of ​​the device to measure the magnetic induction value, pressure value, or capacitance value of the device. Through experimental measurements, a relatively accurate judgment threshold can be obtained, improving the accuracy of the identification results of whether there is a device to be charged within the wireless charging sensing area of ​​the device.

[0130] As an example, the preset magnetic characteristics may include, but are not limited to, one or more of the preset magnetic field strength change value and preset magnetic field strength change rate; the preset pressure characteristics may include, but are not limited to, one or more of the preset pressure strength change value and preset pressure strength change rate; and the preset capacitance characteristics may include, but are not limited to, one or more of the preset capacitance change value and preset capacitance change rate, etc., without limitation.

[0131] If there is a device to be charged within the wireless charging sensing area, execute S704; if there is no device to be charged within the wireless charging sensing area, the device re-executes S701.

[0132] S704, Device initiates wireless charging detection.

[0133] As one possible implementation, the device can automatically enable the TRX chip or TX chip in the background to initiate wireless charging detection.

[0134] If wireless charging is successfully detected, execute S705.

[0135] S705, The device charges the device to be charged.

[0136] based on Figure 7AThe wireless charging activation method described herein allows the device to detect collisions. When a collision occurs, sensors detect data and determine if the data meets preset characteristics to ascertain whether a device to be charged exists within the device's wireless charging sensing area. If the data meets the preset characteristics, the device initiates wireless charging detection, such as wireless reverse charging detection. Based on this, when a user brings a device requiring charging close to the device, and / or when the user performs a quick "tap" operation on the device, the device can recognize this action through collision detection and further clarify whether a device to be charged exists within the device's wireless charging sensing area through sensor detection. When the data meets the preset characteristics, the device's wireless charging detection is triggered promptly, accurately, and reliably, reducing the power consumption caused by unnecessary wireless charging detection. Especially for electronic devices with wireless reverse charging capabilities, this solution avoids the impact of unnecessary wireless charging detection on the electronic device's battery life, improving the user experience.

[0137] Compared to Figure 1A The device shown directly wakes up the device to be charged by sending a Ping signal. Figure 7A The proposed solution can trigger wireless charging detection in a timely, accurate, and reliable manner, reducing the power consumption of the device caused by unnecessary wireless charging detection; compared to... Figure 1B The solution shown is to manually enable the wireless reverse charging detection function. Figure 7A The proposed solution avoids the inconvenience caused to users by the cumbersome process of enabling the wireless reverse charging detection function; compared to Figure 2 The scheme shown triggers wireless reverse charging detection by detecting the Q value. Figure 7A The proposed solution not only saves power consumption during the initial reverse charging detection but also avoids wireless reverse charging detection triggered by changes in the Q-value caused by objects in the surrounding magnetic field that do not require charging. This reduces the possibility of false triggering of the wireless reverse charging detection function and minimizes the power consumption caused by unnecessary wireless charging detection. Compared to... Figure 3 The diagram shows a scheme for attaching and fixing the device to be charged using a magnetic attachment component. Figure 7A The proposed solution eliminates the need for additional magnetic components and pressure sensors at their corresponding locations. The existing conventional accelerometer and magnetic sensor in the device can trigger wireless charging detection in a timely, accurate, and reliable manner, thus reducing costs.

[0138] As an example, please refer to Figure 7B , Figure 7B Taking the device's collision detection via an accelerometer and magnetic induction information via a magnetic sensor as an example, a schematic diagram illustrating a process for triggering wireless charging detection provided in this application embodiment is shown. Figure 7BAs shown, after executing S1-S4, S5 can be executed to perform wireless charging detection. S1-S5 are as follows:

[0139] S1. The device detects the acceleration value of the device through an acceleration sensor.

[0140] For example, the device can detect acceleration values ​​in multiple directions using an acceleration sensor.

[0141] S2. The device determines whether the acceleration value meets the preset acceleration characteristics.

[0142] For an introduction to S1-S2, please refer to the explanation of S701 above, which will not be repeated here.

[0143] If the acceleration value meets the preset acceleration characteristics, the device executes S3; if the acceleration value does not meet the preset acceleration characteristics, the device executes S1.

[0144] S3. The device collects magnetic induction information through a magnetic sensor.

[0145] S4. The device determines whether the magnetic induction information meets the preset magnetic characteristics.

[0146] For an introduction to S3-S4, please refer to the explanation of S702-S703 above, which will not be repeated here.

[0147] If the magnetic induction information meets the preset magnetic force characteristics, the device executes S5; if the magnetic induction information does not meet the preset magnetic force characteristics, the device executes S1.

[0148] S5. The device initiates wireless charging detection.

[0149] For an introduction to S5, please refer to the description of S704 above; it will not be repeated here. Figure 7B Taking the device's acquisition of magnetic induction information via a magnetic sensor as an example, the process of triggering wireless charging detection when the device acquires data via pressure sensors, capacitance sensors, or one or more other sensors can be found in the section above. Figure 7B The process shown will not be described in detail here.

[0150] based on Figure 7BThe method for triggering wireless charging detection, as shown, involves the device detecting collisions using an accelerometer. Upon collision, a magnetic sensor detects whether a magnetically capable device is within the wireless charging sensing area. If a magnetically capable device is detected within the sensing area, the device initiates wireless charging detection, such as reverse wireless charging detection. Based on this, when a user brings a device close to the device, the device can recognize this action through collision detection and further clarify whether a magnetically capable device is within the sensing area. When a magnetically capable device is found within the sensing area, the device promptly, accurately, and reliably triggers wireless charging detection, reducing the power consumption caused by unnecessary wireless charging detection. Especially for electronic devices with reverse wireless charging capabilities, this solution avoids the impact of unnecessary wireless charging detection on battery life, improving the user experience.

[0151] As an example, the power consumption of a certain model of device under different schemes was measured, and the power consumption shown in Table 1 is as follows. As shown in Table 1, compared to... Figure 2 The power consumption of 11.2mAh / 24h resulting from the scheme of triggering wireless reverse charging detection by detecting the Q value, as shown, and Figure 1A The diagram shows the power consumption (0.6W~1.2W)*24h resulting from the scheme of waking up the device to be charged by periodically sending Ping signals. Figure 7B The power consumption during the initial reverse charging detection of the scheme shown is approximately zero and can be ignored.

[0152] Table 1

[0153]

[0154] In some embodiments, wireless charging detection may include: the device sending a wake-up signal, for example, the device enabling the TX chip to send a wake-up signal to wake up the device to be charged located within the wireless charging sensing area of ​​the device. Exemplarily, the wake-up signal may include, but is not limited to, a Digital Ping signal (referred to as "Ping signal" in this embodiment).

[0155] As an example, the device can send a wake-up signal according to a transmission cycle and check whether a response signal meeting the conditions (such as a Ping signal) is received to determine whether the device to be charged is in a connectable state. For example, if the device receives a response signal meeting the conditions, the device starts to enable the TRX chip or TX chip to wirelessly charge the device to be charged; if the device does not receive a response signal meeting the conditions, the device considers the device to be charged to be in a disconnectable state, reminds the user, and / or stops sending wake-up signals.

[0156] In some embodiments, wireless charging detection may include: performing a Q-value scan to further determine whether an object within the wireless charging sensing area is a device to be charged; successful charging detection includes: a Q-value greater than a reference Q-value. For example, if the Q-value is greater than the reference Q-value, the device determines that the object within the wireless charging sensing area is a device to be charged; if the Q-value is less than or equal to the reference Q-value, the device determines that the object within the wireless charging sensing area is not a device to be charged.

[0157] In some embodiments, wireless charging detection may include performing a Q-value scan and sending a wake-up signal after the Q-value meets a condition; for example, if the Q-value is greater than a reference Q-value, the device sends a wake-up signal, and if the Q-value is less than or equal to the reference Q-value, the device does not send a wake-up signal; successful charging detection includes receiving a response signal that meets the condition.

[0158] As an example, please refer to Figure 8 , Figure 8 A flowchart illustrating a wireless charging detection and wireless charging process according to an embodiment of this application is shown. Figure 8 As shown, wireless charging detection may include S801A and S802-S804, or S801B and S802-S804, or S801A-S801B and S802-S804, and the wireless charging process may include S805-S809:

[0159] S801A: The device performs a Q-value scan and determines that the Q-value is greater than the reference Q-value.

[0160] As an example, the baseline Q value may be determined in advance, which is the Q value of the wireless charging coil when there is no device to be charged within the wireless charging sensing area of ​​the device.

[0161] If the scanned Q value is greater than the reference Q value, the device executes S801B or S802.

[0162] S801B, the device sends a wake-up signal.

[0163] The wake-up signal is used to wake up the device to be charged located within the wireless charging sensing area of ​​the device.

[0164] For example, the wake-up signal may include, but is not limited to, the Ping signal.

[0165] As an example, the device can send a wake-up signal according to the transmission cycle and check whether a response signal that meets the conditions is received, such as whether a response signal that meets the conditions (such as a Ping signal) is received within a certain time (such as 5 seconds), in order to determine whether the device to be charged is in a connectable state.

[0166] In some embodiments, if the device does not receive a response signal that meets the conditions, the device assumes that the device to be charged is in an unconnectable state, and reminds the user and / or stops sending wake-up signals.

[0167] In some embodiments, if the device receives a response signal that meets the conditions, the device executes S802.

[0168] S802, The device performs protocol initialization.

[0169] The protocol initialization is used to initialize settings based on wireless charging protocols supported by both the device and the device being charged.

[0170] As one possible implementation, the device and the device to be charged can exchange basic information about each other, including but not limited to one or more of the wireless charging standard versions they support, device models, etc. The device can determine the wireless charging protocol version based on its own and the device to be charged's basic information, and perform the initialization settings of the wireless charging protocol.

[0171] As an example, wireless charging protocols may include, but are not limited to, the Qi protocol, the Ki wireless kitchen standard protocol, industrial wireless charging standards, light electric vehicle (LEV) standards, in-band wireless charging control protocols, etc. The specific wireless charging protocol used by the device depends on the specific device type, device function, charging scenario, etc., and this application embodiment does not limit it.

[0172] Protocol initialization ensures that both parties communicate under the same protocol during the wireless charging process, guaranteeing the safety, reliability, and efficiency of the wireless charging process.

[0173] S803, The device exchanges charging parameters with the device to be charged.

[0174] The device interacts with the device to be charged to exchange charging parameters, allowing them to obtain each other's charging requirements.

[0175] As an example, the device to be charged may send one or more parameters such as the current battery level, the desired charging cutoff level, the maximum acceptable charging voltage and current.

[0176] As an example, the device can send one or more parameters to the device to be charged, such as the maximum output power that the device can provide, the adjustable voltage and current levels.

[0177] By exchanging charging parameters, both parties can ensure that they use agreed-upon and reasonable charging parameters for wireless charging, thus guaranteeing the safety, reliability, and efficiency of the wireless charging process.

[0178] S804. The device negotiates power with the device to be charged.

[0179] The device negotiates power with the device to be charged to obtain suitable wireless charging power for both devices.

[0180] As an example, assuming the device supports the optimal wireless charging power for the device being charged, the device can negotiate with the device to use that optimal wireless charging power to wirelessly charge it. For instance, if the device being charged can support wireless charging at a maximum power of 10kW, and assuming the device can provide that power of wireless charging output, then both parties can agree that the device will wirelessly charge the device at 10kW.

[0181] As an example, if a device cannot support the optimal wireless charging power of the device being charged, it can negotiate with the device to adjust the charging power based on one or more principles such as priority and compatibility, until both parties agree. For instance, if the device being charged can support wireless charging at a maximum power of 10kW or 8kW, and the device can only provide a maximum wireless charging output of 8kW, it can negotiate with the device to decide to wirelessly charge the device at 8kW based on one or more principles such as priority and compatibility. Similarly, if the device being charged can support wireless charging at a maximum power of 8kW, and the device can only provide a maximum wireless charging output of 10kW, it can negotiate with the device to decide to wirelessly charge the device at 8kW based on one or more principles such as priority and compatibility.

[0182] S805, the device wirelessly charges the device to be charged.

[0183] For example, the device can power on the TRX or TX chip, causing the wireless charging coil to generate an alternating magnetic field. The wireless charging coil of the device being charged will then generate an alternating current due to electromagnetic induction. The device being charged can then rectify this alternating current to convert it into direct current, transforming the unstable DC voltage after rectification into a stable voltage value suitable for the operation of the device's internal circuitry. In this way, the device can wirelessly charge the device being charged.

[0184] S806, The device adjusts its power.

[0185] As one possible implementation, during the process of wirelessly charging the device to be charged, the device can obtain the status parameters of the battery of the device to be charged in a timely manner, such as one or more status parameters including but not limited to temperature, voltage, and current, and dynamically adjust the wireless charging power according to the status parameters of the battery of the device to be charged.

[0186] As an example, if the battery temperature of the device being charged is too high during the wireless charging process, the device can reduce the wireless charging detection power; when the battery temperature of the device being charged returns to the normal range, the device can appropriately increase the wireless charging power according to the actual situation.

[0187] By acquiring the battery status parameters of the device to be charged in real time and adjusting the wireless charging power accordingly, the wireless charging process can be ensured to be safe, reliable, and efficient.

[0188] S807, The device obtains the charging status.

[0189] As one possible implementation, during the process of wirelessly charging the device to be charged, the device can obtain the charging status of the device in a timely manner, such as including but not limited to one or more of the charging time, the amount of electricity charged, and the current charging power. This allows the device to end the wireless charging in a timely manner when a certain charging status is reached, further avoiding the waste of device power and ensuring device safety.

[0190] In some embodiments, the device can also display the charging status of the device to be charged to the user, so that the user can understand the progress of wireless charging.

[0191] S808: The device determines whether to end wireless charging based on the charging status.

[0192] As one possible implementation, the device can determine whether to end wireless charging based on the charging status and preset conditions. For example, the preset conditions may include, but are not limited to, one or more of the following: the charging time is a preset duration, the amount of electricity charged is a preset amount, and the current charging power is a preset power value.

[0193] If the device determines to end wireless charging based on the charging status, the device executes S809; if the device determines not to end wireless charging based on the charging status, the device executes S806.

[0194] S809, The device has finished wireless charging.

[0195] As one possible implementation, the device can deactivate the TRX chip or TX chip to end wireless charging of the device to be charged.

[0196] Figure 8 As examples of several possible wireless charging detection and wireless charging processes, in some embodiments, wireless charging detection may further include: communicating with the device to be charged via one or more methods such as NFC communication and Bluetooth communication; determining, based on the communication status, whether an object within the wireless charging sensing area has the function of receiving wireless charging; and, when the object colliding with the device has the function of receiving wireless charging, the device may execute... Figure 8 As shown in S805-S809; when the object being colliding with the device does not have the function of receiving wireless charging, the device does not perform the following: Figure 8 S805-S809 are shown.

[0197] By combining one or more methods such as Q-value scanning, NFC communication, and Bluetooth communication to determine whether an object within the wireless charging sensing area is capable of receiving wireless charging, the false trigger rate of wireless charging detection can be further reduced, the accuracy and reliability of identifying users' wireless charging needs can be improved, and the power consumption of the device can be further reduced due to unnecessary wireless charging detection.

[0198] Figure 7A and Figure 7B The illustrated scheme uses a device that combines collision detection and sensor detection to identify a user's wireless charging need as an example. In some embodiments, the device can also identify a user's wireless charging need solely based on collision detection, activating wireless charging detection when a collision is detected. Alternatively, in some embodiments, the device can also identify a user's wireless charging need solely based on sensor detection, activating wireless charging detection when it is determined that there is a device to be charged within the wireless charging sensing area.

[0199] For example, the device can also be based solely on Figure 9A The collision detection steps S1-S2 shown identify the user's wireless charging request. When a collision is detected, step S5 is executed to perform wireless charging detection. If the wireless charging detection is successful, the device to be charged is charged. Alternatively, taking the device collecting magnetic induction information via a magnetic sensor as an example, the device can also be based solely on... Figure 9B The magnetic induction steps S3-S4 shown identify the user's wireless charging needs. When it's determined that a device to be charged exists within the wireless charging sensing area based on the magnetic induction information, step S5 is executed to perform wireless charging detection. Upon successful wireless charging detection, the device to be charged is then charged. (About...) Figure 9A S1-S2 and S5 are shown, and Figure 9B The descriptions of S3-S4 and S5 shown above can be found in the text above. Figure 7B The relevant explanations will not be repeated here.

[0200] In some embodiments of this application, the device can further determine the user's wireless charging needs by combining one or more other detection methods, in addition to collision detection and detection by one or more sensors such as magnetic detection, pressure detection, and capacitance detection. For example, in response to detecting a collision, the device can collect data (such as magnetic induction information, pressure information, capacitance information, etc.) and determine whether the data meets preset characteristics. If the preset characteristics are met, the device can further determine the user's wireless charging needs by combining one or more other detection methods. In this way, the false trigger rate of wireless charging detection can be further reduced, the accuracy and reliability of identifying the user's wireless charging needs can be improved, and the power consumption caused by unnecessary wireless charging detection can be reduced.

[0201] As an example, the device can perform scene recognition based on collision detection and sensor detection, and initiate wireless charging detection when it determines that it is in a first scene type and / or not in a second scene type. For example, the first scene type may include, but is not limited to, one or more of the following: a stationary scene, a handheld scene, etc., and the second scene type may include, but is not limited to, one or more of the following: a backpack scene, a pocket scene, etc.

[0202] For example, please refer to Figure 10 , Figure 10 Taking the device's collision detection via an accelerometer and magnetic induction information via a magnetic sensor as an example, this application provides another schematic diagram of the process for triggering wireless charging detection.

[0203] like Figure 10 As shown, the process of triggering wireless charging detection may include S1-S4, S6-S7, and S5:

[0204] S1. The device detects the acceleration value of the device through an acceleration sensor.

[0205] S2. The device determines whether the acceleration value meets the preset acceleration characteristics.

[0206] S3. The device collects magnetic induction information through a magnetic sensor.

[0207] S4. The device determines whether the magnetic induction information meets the preset magnetic characteristics.

[0208] For an introduction to S1-S4, please refer to the above text. Figure 7B The explanation will not be repeated here.

[0209] If the magnetic induction information meets the preset magnetic force characteristics, the device executes S6; if the magnetic induction information does not meet the preset magnetic force characteristics, the device executes S1.

[0210] S6. The device acquires environmental information.

[0211] The environmental information acquired by the device is used to determine the scene in which the device is located. For example, the scene in which the device is located may include, but is not limited to, one or more of the following: a static scene, a handheld scene, a backpack scene, a pocket scene, a work scene, and a vehicle scene.

[0212] As one possible implementation, the device can acquire relevant data through a third sensor to obtain environmental information. For example, the third sensor may include, but is not limited to, one or more of an accelerometer, an ambient light sensor, and a camera, and the environmental information includes, but is not limited to, one or more of the following: ambient light information, environmental images, and motion information.

[0213] As an example, the third sensor is the same sensor as the first and / or second sensor. For instance, the third sensor is a pressure sensor, as are the first and / or second sensors.

[0214] S7. The device determines the scene in which it is located based on environmental information.

[0215] If the device is in the first scene type and / or not in the second scene type, the device executes S5; if the device is not in the first scene type and / or is in the second scene type, the device abandons the execution of S5 and executes S1 instead. For example, the first scene type may include, but is not limited to, one or more of the following: a static scene, a handheld scene, etc., and the second scene type may include, but is not limited to, one or more of the following: a backpack scene, a pocket scene, etc.

[0216] In some embodiments, the device may mark a flag after determining the scene in which the device is located. For example, a first flag may be marked when the device is in a first scene type and / or not in a second scene type, and a second flag may be marked when the device is not in the first scene type and / or in the second scene type. Exemplarily, the first flag is 0 and the second flag is 1; or, the first flag is 1 and the second flag is 0, without limitation.

[0217] In some embodiments, the device can periodically acquire environmental information according to a preset scene recognition cycle, determine the scene in which the device is located based on the environmental information, and modify the flag bit when the scene changes.

[0218] S5. The device initiates wireless charging detection.

[0219] For an introduction to S5, please refer to the above text. Figure 7B The explanation will not be repeated here.

[0220] Figure 10Taking the device's acquisition of magnetic induction information via a magnetic sensor as an example, the process of triggering wireless charging detection when the device acquires data via pressure sensors, capacitance sensors, or one or more other sensors can be found in the section above. Figure 10 The process shown will not be described in detail here.

[0221] Figure 10 Taking the example of the device performing collision detection and sensor detection first, and then scene recognition, in some embodiments, the device may also perform scene recognition first, and then collision detection and sensor detection; or the device may perform scene recognition and collision detection simultaneously; or the device may perform collision detection first, then scene recognition, and then sensor detection; or the device may perform collision detection first, and then perform scene recognition and sensor detection simultaneously. The embodiments of this application do not limit the specific timing of scene recognition, but depend on the time corresponding to the scene recognition cycle.

[0222] As an example, the device can first perform collision detection and data acquisition. Then, based on the data, if it determines that there is a device to be charged within the wireless charging sensing area, it performs scene recognition. When it is determined that the device is in a first scene type and / or not in a second scene type, it initiates wireless charging detection. In this way, unnecessary power consumption caused by accidental collisions between devices in a backpack / pocket and the acquisition of data that meets preset characteristics can be avoided in the first scene category, such as backpack scenes and pocket scenes.

[0223] As an example, the device can first perform scene recognition, and if it determines that it is in a first scene type and / or not in a second scene type, it will not perform collision detection and data collection. In this way, unnecessary power consumption caused by performing collision detection, data collection, and wireless charging detection can be avoided in the first scene category, such as backpack scene or pocket scene, where the user is unlikely to trigger wireless charging.

[0224] As an example, the device can identify the scene during collision detection or data acquisition, and stop collision detection or data acquisition when it determines that the scene is in a first scene type and / or not in a second scene type. This avoids unnecessary power consumption caused by performing collision detection, data acquisition, and wireless charging detection in first scene categories where the user is unlikely to trigger wireless charging, such as backpack or pocket scenarios.

[0225] For example, after scene recognition, the device can mark the scene. When the marker is the first marker, it determines that the device is in the first scene type and / or not in the second scene type, and performs collision detection and sensor detection. When the marker is the second marker, no further action is taken, and environmental information acquisition and scene recognition are performed again in the next scene recognition cycle. The marker can be viewed by the device at any time. For example, the device can check the marker during collision detection and sensor detection, and stop collision detection or sensor detection and other operations related to determining the user's wireless charging needs when the marker is the second marker.

[0226] As an example, please refer to Figure 11 , Figure 11 Taking the example of a device performing collision detection via an accelerometer, collecting magnetic induction information via a magnetic sensor, and scene recognition occurring before collision detection and magnetic detection, a schematic diagram of the process of triggering wireless charging detection provided in this application embodiment is shown.

[0227] like Figure 11 As shown, the process of triggering wireless charging detection may include S6-S7, or may include S6-S7 and S1-S5:

[0228] S6. The device acquires environmental information.

[0229] S7. The device determines the scene in which it is located based on environmental information.

[0230] Regarding S6-S7, please refer to the above text. Figure 10 The explanation will not be repeated here.

[0231] If the device is in the first scene type and / or not in the second scene type, the device executes S1; if the device is not in the first scene type and / or is in the second scene type, the device does not start wireless charging detection. For example, the device may continue to perform the collision detection shown in S1 and / or temporarily execute S6-S7 at the time corresponding to the scene recognition cycle.

[0232] S1. The device detects the acceleration value of the device through an acceleration sensor.

[0233] S2. The device determines whether the acceleration value meets the preset acceleration characteristics.

[0234] S3. The device collects magnetic induction information through a magnetic sensor.

[0235] S4. The device determines whether the magnetic induction information meets the preset magnetic characteristics.

[0236] If the magnetic induction information meets the preset magnetic characteristics, the device executes S5; if the magnetic induction information does not meet the preset magnetic characteristics, the device executes S1. In some embodiments, if the moment corresponding to the scene recognition cycle arrives, the device may also execute S6-S7.

[0237] S5. Device initiates wireless charging detection. For a description of S1-S5, please refer to the section above. Figure 7B The explanation will not be repeated here.

[0238] based on Figure 10 The proposed solution involves scene recognition based on collision detection and magnetic detection, and determining whether to trigger wireless charging detection based on the scene recognition results. This avoids unnecessary power consumption caused by performing wireless charging detection in scenarios with a high probability of accidental collisions, even when the user does not actually need wireless charging.

[0239] For example, in scenarios such as backpacks or pockets, users typically do not initiate the action of bringing one device close to another. Therefore, the collision detected by the device is most likely due to accidental collisions between devices inside the backpack / pocket. In this case, the device can promptly identify and not trigger wireless charging detection, which can further reduce the false trigger rate of wireless charging detection, improve the accuracy and reliability of identifying users' wireless charging needs, and thus further reduce the power consumption caused by unnecessary wireless charging detection.

[0240] For example, in static or handheld scenarios, the likelihood of accidental touches is relatively low. In such cases, the device can promptly meet the user's wireless charging needs and improve the user experience.

[0241] In the embodiments of this application Figure 8 The three examples of wireless charging detection and wireless charging process shown can be implemented based on any of the wireless charging detection processes in the above embodiments.

[0243] For example, please refer to Figure 13 , Figure 13 It shows Figure 8 The wireless charging detection and wireless charging process shown are based on Figure 10 The example shown illustrates how the process of triggering wireless charging detection is implemented. Figure 13 As shown, the process of triggering wireless charging detection may include S1-S4 and S6-S7. If the device determines that it is in the first scene type and / or not in the second scene type based on the environmental information, the device executes S801A and S802-S809, or executes S801B and S802-S809, or executes S801A-S801B and S802-S809.

Figure 14 As shown, the process of triggering wireless charging detection may include S6-S7 and S1-S4. If the magnetic induction information collected by the device meets the preset magnetic characteristics, the device executes S801A and S802-S809, or executes S801B and S802-S809, or executes S801A-S801B and S802-S809.

The process of triggering wireless charging detection may include... Figure 9B As shown in S3-S4, if the magnetic induction information collected by the device meets the preset magnetic characteristics, the device executes S801A and S802-S809, or executes S801B and S802-S809, or executes S801A-S801B and S802-S809.
