The described embodiments should not be construed as limitations on the present application.

[0026] An embodiment of the present application provides a data transmission method. The method is applied to an electronic device, and the electronic device includes a wireless charging module; Figure 1 Schematic implementation process of a data transmission method provided by an embodiment of the present application Figure 1 ,such as Figure 1 shown, the method includes the following steps 101 to step 102:

[0027] Step 101, in response to the wireless charging module being in a working state, establish a communication connection between the electronic device and the device to be charged;

[0028] Step 102: Based on the communication connection, receive the first data transmitted by the device to be charged.

[0029] It can be understood that in the embodiments of the present application, in response to the wireless charging module in the electronic device charging the device to be charged, a communication connection is established between the electronic device and the device to be charged; and based on this communication connection, the first data transmitted by the device to be charged is received. That is to say, the wireless charging module can trigger the connection between the device to be charged and the electronic device in the working state. In this way, during the charging process, automatic data transmission can be achieved, that is, the time for charging the device to be charged can be fully utilized to achieve automatic data transmission, thereby improving the data transmission efficiency and simplifying the operation burden / operation steps in the data transmission process.

[0030] The further optional implementation manners of the above steps and related terms will be described below.

[0031] In step 101, in response to the wireless charging module being in the working state, a communication connection is established between the electronic device and the device to be charged.

[0032] It should be understood that in the embodiments of the present application, the wireless charging module is not limited. The wireless charging module is a component that transmits electrical energy to the device to be charged through a non-physical contact method (such as electromagnetic induction, magnetic resonance, or radio wave).

[0033] In some embodiments, the wireless charging module uses the principle of electromagnetic induction to implement the function of charging the device to be charged. The transmitting coil (i.e., the wireless charging module) passes alternating current to generate a magnetic field, and the receiving coil (i.e., the device to be charged) induces current and converts it into direct current to charge the device to be charged (such as the Qi standard); among them, the Qi standard is the international mainstream wireless charging technology standard, formulated and promoted by the Wireless Power Consortium (WPC). Its core goal is to achieve wireless charging compatibility between devices of different brands.

[0034] In other embodiments, the wireless charging module uses the principle of magnetic resonance to implement the function of charging the device to be charged, and realizes medium-distance charging through resonance frequency matching.

[0035] In still other embodiments, the wireless charging module uses the principle of radio wave (far-field radiation) to implement the function of charging the device to be charged. This principle has low power consumption and is suitable for low-power devices.

[0036] In the embodiments of the present application, "the wireless charging module is in a working state" can be understood as that the wireless charging module is performing the function of power transmission. That is, an alternating current is passed through the coil of the transmitting end (i.e., the wireless charging module) to generate an alternating magnetic field; the coil of the receiving end (i.e., the device to be charged) induces a current and charges the device to be charged through a rectifying circuit.

[0037] It should be understood that in the embodiments of the present application, "establishing a communication connection between the electronic device and the device to be charged" can be understood as enabling the electronic device and the device to be charged to transmit data, signals or information to each other through a certain communication medium and protocol.

[0038] In the embodiments of the present application, there is no limitation on the device to be charged, and the device to be charged can perform wireless charging and information transmission. In some embodiments, the device to be charged includes, but is not limited to, at least one of the following: mobile phone, tablet computer, smart home device (e.g., smart table lamp), Bluetooth headset, Bluetooth keyboard, smart bracelet, etc.

[0039] In some embodiments, the electronic device further includes a detection module, and the detection module is communicatively connected to the wireless charging module; the method further includes: enabling the wireless charging module in response to the induction area of the wireless charging module being in a first state; wherein the first state includes: the state in which the device to be charged is placed on the induction area; based on a clock signal, controlling the detection module to poll whether the wireless charging module enables a wireless charging operation, and when the wireless charging module enables the wireless charging operation, determining that the wireless charging module is in a working state.

[0040] It should be understood that in the embodiments of the present application, there is no limitation on the induction area of the wireless charging module, and the induction area of the wireless charging module is the core range where the device can effectively receive electric energy. Wireless charging generates an alternating magnetic field through a coil (transmitting end), and the coil of the receiving end (i.e., the device to be charged) induces a current in the magnetic field to achieve energy transmission. The induction area is the spatial range where the magnetic field strength is sufficient to efficiently transmit energy. The induction area is the "effective energy channel" of wireless charging, and its design needs to balance efficiency, cost and user experience. The user only needs to place the device to be charged within the range of the induction area and ensure that there is no metal barrier to enjoy convenient wireless charging.

[0041] In the embodiments of the present application, when the device to be charged is placed on the induction area, the wireless charging module is changed from the "to-be-charged state" to the "charging state"; through a clock signal, periodically controlling the detection module to query whether the wireless charging module enters the "charging state", that is, querying whether the wireless charging module enables a wireless charging operation; when the wireless charging module enters the "charging state", determining that the wireless charging module is in a working state.

[0042] In some embodiments, the electronic device further includes a detection module, and the detection module is communicatively connected to the wireless charging module; the method further includes: enabling the wireless charging module in response to the induction area of the wireless charging module being in a first state; wherein, the first state includes: a state in which the device to be charged is placed on the induction area; determining that the wireless charging module is in an operating state based on the information that the wireless charging module is in an operating state sent by the wireless charging module to the detection module.

[0043] It should be understood that in the embodiments of the present application, when a device to be charged is placed on the induction area, the wireless charging module is caused to enter the "charging state" from the "awaiting charging state"; at this time, the wireless charging module actively sends information that the wireless charging module is in an operating state to the detection module, thereby determining that the wireless charging module is in an operating state.

[0044] In the embodiments of the present application, the wireless charging module can communicate bidirectionally with the detection module. That is to say, during the process of "controlling the detection module to poll whether the wireless charging module enables wireless charging operation based on a clock signal", if the wireless charging module enters the "charging state", it will also actively send information that the wireless charging module is in an operating state to the detection module.

[0045] In some embodiments, establishing the communication connection between the electronic device and the device to be charged includes: establishing a pairing connection between the electronic device and the device to be charged; based on the pairing connection, establishing the communication connection between the electronic device and the device to be charged.

[0046] In the embodiments of the present application, "establishing the pairing connection between the electronic device and the device to be charged" can be understood as the process of establishing a secure and stable communication link between the electronic device and the device to be charged. The core is to ensure that both parties can reliably exchange data through protocol handshake, authentication, and parameter negotiation. In some embodiments, the pairing connection includes, but is not limited to, at least one of the following: Bluetooth pairing, Near Field Communication (NFC) pairing, infrared pairing, Wireless Fidelity (Wi-Fi) pairing, out-of-band pairing, etc.

[0048] It can be understood that in the embodiments of the present application, when it is determined that the wireless charging module is in a working state, that is, when the detection module determines that the wireless charging module enables wireless charging operation, a pairing connection between the electronic device and the device to be charged will be triggered. After successful pairing, a network connection is established through a network protocol for data transmission. In this way, the user only needs to place the device to be charged in the induction area of the wireless charging module, and data transmission between the electronic device and the device to be charged can be achieved. The operation is convenient, and during the data interaction process, the device to be charged is continuously charged, so as to make full use of the charging time and improve the efficiency of data transmission.

[0049] In the embodiments of the present application, the first wireless network and the second wireless network are not limited.

Then, a communication connection between the electronic device and the device to be charged is established based on the first wireless local area network / second wireless local area network.

[0052] In some embodiments, establishing a communication connection between the electronic device and the device to be charged based on the pairing connection includes: determining a first wireless network where the electronic device is located and a second wireless network where the device to be charged is located based on the pairing connection; in a case where the first wireless network is different from the second wireless network, providing a third wireless network through the electronic device or the device to be charged, and establishing a communication connection between the electronic device and the device to be charged based on the third wireless network.

In this way, only by the user placing the device to be charged in the induction area of the wireless charging module, data transmission between the electronic device and the device to be charged can be achieved, which is convenient to operate. And during the data interaction process, the device to be charged is continuously charged, thus making full use of the charging time and improving the efficiency of data transmission.

In the embodiments of the present application, the electronic device can expand the display content of the device to be charged, or the device to be charged can expand the display content of the device to be charged.

[0066] In the embodiments of the present application, when the device to be charged expands the display content of the device to be charged, the display data includes the expanded display content, and the electronic device only needs to display the display screen corresponding to the expanded display content. When the electronic device expands the display content of the device to be charged, the display data includes the display content of the device to be charged, and the electronic device displays the display screen corresponding to the expanded display content.

[0081] The following describes an exemplary application of the processing method provided in the embodiments of the present application in an actual scenario.

[0082] The embodiments of the present application provide a data transmission method. Figure 2 It is a schematic implementation process of a data transmission method provided in the embodiments of the present application. Figure 2 , such as Figure 2 shown, this method is a method (i.e., an example of a data transmission method) for triggering the interconnection (i.e., interaction, that is, data transmission) between the mobile phone and the PC through the charging behavior of the built-in wireless charging module of the personal computer (PC) (i.e., an example of an electronic device) by the mobile phone (i.e., an example of a device to be charged).

[0083] In some embodiments, the data transmission method provided by the embodiments of the present application can also be referred to as Qi-Link one-charge transmission, which triggers the interconnection between the mobile phone and the PC through wireless charging in one step. This method allows the mobile phone to easily establish a connection with the PC while using the built-in wireless charging module of the PC, quickly back up or transfer pictures, videos, and documents, and implement mobile phone screen mirroring control. That is, transmission starts as soon as charging begins, greatly simplifying the operation steps and bringing a simpler and more natural interaction experience.

[0084] Figure 3 It is a schematic diagram of the connection of modules in an electronic device provided by the embodiments of the present application. As Figure 3 shown, the Qi-link module is connected to the PC through Universal Serial Bus 2.0 (USB 2.0). The Qi-link module is controlled by a System on a Chip (SoC) with a Bluetooth Low Energy (BLE) / Wi-Fi dual-mode channel. The Qi-link module communicates with the wireless charging module through an Inter-Integrated Circuit (I2C). When the mobile phone is charged, the interconnection is triggered.

[0085] Figure 4 It is a schematic diagram of the implementation process of a data transmission method provided by the embodiments of the present application. Figure 3 As Figure 4 shown, the Qi-link module of the PC periodically polls the status of the wireless charging module. When the mobile phone is placed on the PC charging module (i.e., an example of the induction area of the wireless charging module) to start wireless charging, the Qi-link module will detect the status of the start of wireless charging. This action of starting wireless charging will trigger the Bluetooth pairing behavior (i.e., the PC Bluetooth Low Energy discovers, and the mobile phone waits for the Bluetooth Low Energy connection). After the paired mobile phone and the PC are successfully paired, a network connection is established by network protocols such as Wi-Fi or Wireless Local Area Network, and data transmission is started to synchronize and back up the mobile phone data to the PC, and at the same time, the mobile phone interface is mapped to the PC monitor. If there is a need to operate the mobile phone, there is no need to pick up the mobile phone, and the PC can be used for operation;

[0086] Among them, ACK represents an acknowledgement signal, and NACK represents a non-acknowledgement signal. The pairing between the PC and the mobile phone is established via Bluetooth. There is no limit on the number of times or time for ACK, and it can be connected at any time. After the Bluetooth connection is established, if the mobile phone and the PC are in the same wireless network, they will be automatically connected online. If they are not in the same network, the PC can start the virtual hotspot mode to connect to the mobile phone, or the mobile phone can share the Wi-Fi hotspot with the PC. API refers to the application programming interface. The mobile phone and the PC install the Qi-link application. Functions such as photo transfer, file transfer, shared clipboard, screen mirroring, etc. can be set in this APP. These functions can be freely operated and realized during the operation of the shared API (i.e., during the operation of the Qi-Link computing shared API) after the mobile phone and the PC are connected.

[0087] Figure 5 It is a schematic diagram of the circuit connection of an electronic device provided by an embodiment of the present application. As Figure 5 shown, the Qi-link module is set on the charging base and can be laid out (i.e., layout) on a printed circuit board (PCB) together with the wireless charging module, or can be independently laid out and connected through a connector. Vbus is the power output for 12V power supply, and the LDO converts the Vbus to 5V or 3.3V voltage to supply power to the Qi-link module. Coil represents the coil. The base is only the placement position of the module, and the electrical connection is the power supply interface and the USB interface.

[0088] The clock and the antenna are part of the Qi-link module. The clock is used to provide periodic pulse signals for the control I2C and serves as the basis for the system timing logic. The antenna is used to realize signal transmission between wireless devices, such as direct data transmission between the mobile phone and the PC. The wireless charging module needs to establish communication with the Qi-link module.
