[0023] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0024] To enable those skilled in the art to better understand the solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] In the embodiments of this application, it should be noted that, in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0026] Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] In the description of the embodiments of this application, the words "example" or "for example" are used to indicate exemplification, illustration, or description. Any embodiment or design described as "example" or "for example" in the embodiments of this application is not to be construed as being more preferred or having more advantages than another embodiment or design. The use of the words "example" or "for example" is intended to present relative concepts in a clear manner.

[0028] Furthermore, in the embodiments of this application, "multiple" refers to two or more. Therefore, in the embodiments of this application, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two, or more. For example, including at least one means including one, two, or more, and is not limited to which ones are included. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A and B and C.

[0029] It should be noted that in the embodiments of this application, "and / or" describes the relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects before and after it are in an "or" relationship.

[0030] It should be noted that in the embodiments of this application, "connection" can be understood as electrical connection. The connection between two electrical components can be a direct or indirect connection between the two electrical components. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0031] In related technologies, when a power supply device performs fast charging for a powered device based on a proprietary fast charging protocol, it typically uses the DP and DM pins of the Type-C interface for fast charging protocol communication. However, since USB 2.0 data transmission also requires the DP and DM pins, in actual fast charging, these pins are prioritized for fast charging protocol communication, preventing USB 2.0 data transmission. Therefore, when a device is in fast charging mode, USB 2.0 data communication is usually not possible simultaneously, creating a functional mutual exclusion.

[0032] The interface control method provided in this application embodiment can be applied to... Figure 1 The first electronic device 100 shown includes a first interface 10. Please refer to [link / reference]. Figure 1 As shown, the first interface 10 includes a first pin 10a and a first target sub-pin 11a spaced apart by a first target pin 11, and a second pin 10b and a second target sub-pin 12a spaced apart by a second target pin 12. The first electronic device 100 can be an electronic device supporting a fast charging protocol.

[0033] And, as Figure 1 As shown, corresponding pads can be set for the first pin 10a, the first target sub-pin 11a, the second pin 10b, and the second target sub-pin 12a.

[0034] Please see Figure 2 As shown, the second electronic device 200 can be an electronic device supporting a fast charging protocol. The second electronic device 200 includes a second interface 20, which includes a first newly added pin 20a and a first connecting sub-pin 21a spaced apart by the first connecting pin 21, and a second newly added pin 20b and a second connecting sub-pin 22a spaced apart by the second connecting pin 22. Furthermore, corresponding pads can be provided for the first newly added pin 20a, the first connecting sub-pin 21a, the second newly added pin 20b, and the second connecting pin 22a.

[0035] The first electronic device 100 and the second electronic device 200 can be connected via a cable 300. The cable 300 has two connectors 30, one of which connects to the first interface 10 and the other connector 30 connects to the second interface 20. The cable 300 can be a cable that supports a fast charging protocol. Please refer to [link / reference]. Figure 3As shown, the connector 30 includes a first newly added connector pin 30a and a first connector sub-pin 31a spaced apart by the first connector pin 31, and corresponding pads can be provided for the first newly added connector pin 30a and the first connector sub-pin 31a respectively. When the connector 30 is inserted into the first interface 10, the first newly added connector pin 30a is connected to the first pin 10a or the second pin 10b, and the first connector sub-pin 31a is connected to the first target sub-pin 11a or the second target sub-pin 12a; when the connector 30 is inserted into the second interface 20, the first newly added connector pin 30a is connected to the first newly added pin 20a or the second newly added pin 20b, and the first connector sub-pin 31a is connected to the first connecting sub-pin 21a or the second connecting pin 22a.

[0036] Therefore, when the first electronic device 100 and the second electronic device 200 are connected, the first pin 10a is connected to the first newly added pin 20a, and the first target sub-pin 11a is connected to the first connection sub-pin 21a; or, the first pin 10a is connected to the second newly added pin 20b, and the first target sub-pin 11a is connected to the second connection sub-pin 22a; or, the second pin 10b is connected to the first newly added pin 20a, and the second target sub-pin 12a is connected to the first connection pin 21a; or, the second pin 10b is connected to the second newly added pin 20b, and the second target sub-pin 12a is connected to the second connection pin 22a. The first target sub-pin 11a is used to implement the function of the first target pin 11, and the second target sub-pin 12a can be used to implement the function of the second target pin 12. The first pin 10a or the second pin 10b can be configured to implement the function of the first transmission or the second transmission. For example, the pins in the first pin 10a and the second pin 10b that implement the connection between the first electronic device and the second electronic device can be configured to implement a first transmission or a second transmission, or the first pin 10a and the second pin 10b can be configured to implement a first transmission or a second transmission.

[0037] One embodiment of this application provides an interface control method; please refer to [link / reference]. Figure 4 As shown, the interface control method in this embodiment is applied to, for example, Figure 1 The first electronic device 100 shown includes the following steps: Step S11: When the second electronic device is connected, receive the charging protocol information of the current charging device.

[0038] The first electronic device and the second electronic device can be a power receiving device (Sink device) and a power supply device (Source device), respectively, or the first electronic device and the second electronic device can be a power supply device (Source device) and a power receiving device (Sink device), respectively; the second electronic device is connected to the first electronic device so that the Source device charges the Sink device.

[0039] The charging protocol information of the current charging device includes at least the charging protocol information of the second electronic device. For example, if the first electronic device is a mobile terminal and the second electronic device is a power bank without a cable, then the current charging device includes the second electronic device and a cable; or, if the first electronic device is a power bank without a cable and the second electronic device is a mobile terminal, then the current charging device includes the second electronic device and a cable; or, if the first electronic device is a mobile terminal and the second electronic device is a power bank with a cable, then the current electronic device includes the second electronic device; or, if the second electronic device is a mobile terminal and the first electronic device is a power bank with a cable, then the current electronic device includes the second electronic device.

[0040] As one implementation method, the second electronic device can be as follows: Figure 2 and Figure 3 The second electronic device 200 shown can be connected to the first electronic device 100 via a cable 300. The cable 300 has two connectors 30, one of which connects to the first interface 10 and the other to the second interface 20, as detailed above. In this case, the charging protocol information of the current charging device can include the charging protocol information of the second electronic device 200 and the charging protocol information of the cable 300. For example, the second electronic device 200 can be a power bank, and the first electronic device 100 can be a mobile terminal; or, the first electronic device 100 can be a power bank, and the second electronic device 200 can be a mobile terminal.

[0041] As one implementation method, the second electronic device can also be such as Figure 5 The second electronic device 400 shown includes a second connector 40, which comprises a second additional connector pin 40a and a second connector sub-pin 41a spaced apart by the second connector pin 41. When the first electronic device 100 and the second electronic device 400 are connected, the second connector 40 is inserted into the first interface 10, the second additional connector pin 40a is connected to the first pin 10a, and the second connector sub-pin 41a is connected to the first target sub-pin 11a; or, the second additional connector pin 40a is connected to the second pin 10b, and the second connector sub-pin 41a is connected to the second target sub-pin 12a. At this time, the charging protocol information of the current charging device may include the charging protocol information of the second electronic device 400. For example, the second electronic device 400 can be a power bank, specifically a power bank with a built-in connector; the first electronic device 100 is a mobile terminal.

[0042] Step S12: If it is determined from the charging protocol information that the current charging device supports the fast charging protocol, a pin swap command is generated. The pin swap command is used to configure the first pin and / or the second pin to implement the first transmission function, or to configure the first pin and / or the second pin to implement the second transmission function.

[0043] The first transmission function and the second transmission function are two different transmission functions. For example, the first transmission function is used to transmit the first data, and the second transmission function is used to transmit the second data.

[0044] For example, the pins in the first pin 10a and the second pin 10b that implement the connection between the first electronic device and the second electronic device can be configured to implement a first transmission or a second transmission, or the first pin 10a and the second pin 10b can be configured to implement a first transmission or a second transmission.

[0045] In one embodiment, by determining that the second electronic device 200 supports the fast charging protocol based on the charging protocol information of the second electronic device 200 and by determining that the cable 300 supports the fast charging protocol based on the charging protocol information of the cable 300, it can be determined that the current charging device supports the fast charging protocol.

[0046] In other embodiments, if the charging protocol information of the second electronic device 400 indicates that the second electronic device 400 supports the fast charging protocol, then the current charging device can be determined to support the fast charging protocol.

[0047] After determining that the current charging device supports the fast charging protocol, a pin swap command is generated. Based on this command, the first and / or second pins are configured to perform either a first transmission or a second transmission. Specifically, the pin connecting the first and second electronic devices can be configured for either the first or second transmission. Alternatively, both the first and second pins can be directly configured for either transmission. Furthermore, other pins originally used for the first and second transmissions can be configured to perform either transmission solely for the second transmission or solely for the first transmission. In subsequent steps, the first and second transmissions no longer conflict and can proceed simultaneously.

[0048] In this embodiment, the first target pin and the first target sub-pin are separated into intervals in the first interface of the first electronic device, and the second target pin and the second target sub-pin are separated into intervals. When the second electronic device is connected to the first electronic device, if it is determined from the charging protocol information that the current charging device supports the fast charging protocol, the first pin and / or the second pin are configured to perform the first transmission, or the first pin and / or the second pin are configured to perform the second transmission. In this way, the first transmission and the second transmission can be performed simultaneously during the fast charging process.

[0049] In one implementation, the first transmission function and the second transmission function include a fast charging protocol transmission function and a communication data transmission function. For example, the first transmission function is a fast charging protocol transmission function and the second transmission function is a communication data transmission function, or the first transmission function is a communication data transmission function and the second transmission function is a fast charging protocol transmission function.

[0050] In one implementation, the pin swap command is used to configure either the first pin or the second pin to perform a first transmission function. Following step S12, the following steps are also included: Step S131: Perform the first transmission via the first pin or the second pin.

[0051] The first transmission can be used to transmit first data. When the first transmission function is a fast charging protocol transmission function, the first data is fast charging protocol data; when the first transmission function is a communication data transmission function, the first data is communication data, such as USB communication data.

[0052] For example, the pins in the first pin 10a and the second pin 10b that implement the connection between the first electronic device and the second electronic device can be configured to implement a first transmission or a second transmission, or the first pin 10a and the second pin 10b can be configured to implement a first transmission or a second transmission.

[0053] In some implementations, please refer to [the relevant documentation]. Figure 1 As shown, the first interface 10 also includes a third target pin 13 and a fourth target pin 14 for implementing the second transmission function. Following step S12, the following steps are also included: Step S132: Perform a second transmission via the third target pin or the fourth target pin.

[0054] Specifically, during the first transmission via the first pin or the second pin, and during fast charging, the second transmission via the third target pin or the fourth target pin.

[0055] The second transmission can be used to transmit second data. When the second transmission function is a communication data transmission function, the second data is communication data, such as USB communication data; when the second transmission function is a fast charging protocol transmission function, the second data is fast charging protocol data.

[0056] For example, the pin that implements the connection between the first electronic device and the second electronic device in the third or fourth target pin can be configured to implement the second transmission, or the third and fourth target pins can be configured to implement the second transmission.

[0057] In this embodiment, the third target pin and / or the fourth target pin are configured to implement the second transmission function. During fast charging, the first pin or the second pin performs the first transmission, and the third target pin or the fourth target pin performs the second transmission, thus avoiding the conflict between the first transmission and the second transmission during fast charging.

[0058] In some implementations, please refer to [the relevant documentation]. Figure 2 and Figure 3As shown, the second interface 20 of the second electronic device 200 includes a third connection pin 23 and a fourth connection pin 24. The third connection pin 23 and the fourth connection pin 24 are respectively configured to correspond to the third target pin 13 and the fourth target pin 14. Accordingly, the second electronic device 200 configures the first newly added pin 20a and / or the second newly added pin 20b to implement the first transmission function, and configures the third connection pin 23 and / or the fourth connection pin 24 to implement the second transmission function. For example, the pins in the first newly added pin 20a and the second newly added pin 20b that implement the connection between the first electronic device and the second electronic device are configured to implement the first transmission function, and the pins in the third connection pin 23 and the fourth connection pin 24 that implement the connection between the first electronic device and the second electronic device are configured to implement the second transmission function. Alternatively, the first newly added pin 20a and the second newly added pin 20b are configured to implement the first transmission function, and the third connection pin 23 and the fourth connection pin 24 are configured to implement the second transmission function. The connector 30 of the cable 300 also includes a third cable connector pin 33 and a fourth cable connector pin 34, which are respectively configured to correspond to the third target pin 13 and the fourth target pin 14, or the third cable connector pin 33 and the fourth cable connector pin 34 are respectively configured to correspond to the third connection pin 23 and the fourth connection pin 24. For example, the first interface 10 and the second interface 20 can be Type-C interfaces respectively; the first target pin 11 and the second target pin 12 can be CC1 pin and CC2 pin respectively; the first target sub-pin 11a and the second target sub-pin 12a formed after the split can continue to be used as CC1 pin and CC2 pin respectively; the first pin 10a and the second pin 10b are used to implement the first transmission function; the third target pin 13 and the fourth target pin 14 can be DP pin and DM pin respectively; the first connection pin 21 and the second connection pin 22 can be CC1 pin and CC2 pin respectively; the first connection sub-pin 21a and the second connection sub-pin 22a formed after the split can continue to be used as CC1 pin and CC2 pin respectively; the first newly added pin 20a and the second newly added pin 20b are used to implement the first transmission function; the third connection pin 23 and the fourth connection pin 24 can be DP pin and DM pin respectively. The connector 30 of cable 300 can be a Type-C connector, the first connector pin 31 is a CC1 pin, the first connector sub-pin 31a formed by splitting can continue to be a CC1 pin, the first newly added connector pin 30a is used to realize the first transmission function, and the third cable connector pin 33 and the fourth cable connector pin 34 can be DP pin and DM pin respectively.

[0059] In some implementations, please refer to [the relevant documentation]. Figure 5As shown, the second connector 40 of the second electronic device 400 further includes a third connector pin 43 and a fourth connector pin 44. The third connector pin 43 and the fourth connector pin 44 are respectively configured to correspond to the third target pin 13 and the fourth target pin 14. Accordingly, the second electronic device 400 can configure the second newly added connector pin 40a to implement the first transmission function, and configure the third connector pin 43 and / or the fourth connector pin 44 to implement the second transmission function. For example, the pins in the third connector pin 43 and the fourth connector pin 44 that implement the connection between the first electronic device and the second electronic device can be configured to implement the second transmission function, or the third connector pin 43 and the fourth connector pin 44 can be configured to implement the second transmission function. For example, the first interface 10 is a Type-C interface, the second connector 40 is a Type-C connector, the second connector pin 41 can be a CC1 pin, the split second connector sub-pin 41a can continue to be a CC1 pin, the second newly added connector pin 40a is used to implement the first transmission function, and the third connector pin 43 and the fourth connector pin 44 can be a DP pin and a DM pin, respectively.

[0060] In one implementation, the charging protocol information of the current charging device includes a first communication protocol version number sent by the second electronic device 200 and a second communication protocol version number sent by the cable 300. Following step S11, the following step is also included: determining whether the current charging device supports a fast charging protocol based on the charging protocol information, specifically including the following steps: Step S11a: Determine whether the second electronic device supports the fast charging protocol based on the first communication protocol version number; If the first communication protocol version number is the same as the fast charging protocol version number, then the second electronic device is determined to support the fast charging protocol.

[0061] Step S11b: Determine whether the cable supports the fast charging protocol based on the second communication protocol version number; If the second communication protocol version number is the same as the fast charging protocol version number, then the cable is confirmed to support the fast charging protocol.

[0062] Step S11c: When the second electronic device and the cable both support the fast charging protocol, determine that the current charging device supports the fast charging protocol.

[0063] In this embodiment, the first electronic device, the second electronic device, and the cable all support the fast charging protocol, and the functions of the first pin and / or the second pin are configured by exchanging pin commands.

[0064] In some implementations, step S11 specifically includes the following steps: Step S111: When the second electronic device is connected, the charging protocol negotiation process is initiated; Step S112: Receive a negotiation message carrying the first communication protocol version number sent by the second electronic device; Step S113: Receive electronic tag information carrying the second communication protocol version number transmitted by the cable; Step S114: Obtain the first communication protocol version number based on the negotiation message, and obtain the second communication protocol version number based on the electronic tag information.

[0065] In this embodiment, the first communication protocol version number and the second communication protocol version number are obtained as the charging protocol information of the current charging device during the charging negotiation process.

[0066] For example, after the first electronic device and the second electronic device are connected, the first electronic device and the second electronic device perform a device handshake. For instance, the first electronic device sends a handshake pulse, and the second electronic device follows with a charging pulse. Subsequently, the first electronic device sends a handshake command (Ping message) to the second electronic device, and the second electronic device responds with an acknowledgment message (ACK message) to the first electronic device to complete UFCS identification. Specifically, the first electronic device can add the latest supported UFCS protocol version number to the header of the Ping message. After receiving the Ping message, the second electronic device extracts the UFCS protocol version number from the header of the Ping message, compares it with the latest supported UFCS protocol version number, and adds the corresponding first communication protocol version number to the header of the ACK message. Subsequently, the first electronic device and the second electronic device negotiate charging capabilities. Specifically, the first electronic device and the second electronic device exchange their respective voltage and current support ranges. The first electronic device can further adjust the voltage and current according to its battery capacity and charging scenario. Subsequently, the first electronic device and the second electronic device respectively obtain cable electronic tag information. Specifically, cables that support fast charging are usually equipped with USB electronic tags (Electrically Marked). The cable (eMarker) chip, the first electronic device, and the second electronic device determine that the cable supports the fast charging protocol through data interaction with the USB electronic tag chip. The USB electronic tag chip sends an SOP' message or an SOP" message to the first electronic device, writing the second communication protocol version number in the header of the SOP' message or SOP" message. Furthermore, after obtaining the cable electronic tag information, the first and second electronic devices can also execute authentication processes to determine whether they belong to the same brand; for example, both the first and second electronic devices are Apple devices, or both are Huawei devices.

[0067] In one implementation, the pin swap command is used to configure a first pin and / or a second pin to implement a first transmission function, and also to configure a first target sub-pin and / or a second target sub-pin to implement a second transmission function. Specifically, the pin swap command is used to configure the pin that implements the connection between the first electronic device and the second electronic device in the first pin and the second pin to implement the first transmission function, and also to configure the pin that implements the connection between the first electronic device and the second electronic device in the first target sub-pin and the second target sub-pin to implement the second transmission function. Alternatively, the pin swap command is used to configure the first pin and the second pin to implement the first transmission function, and also to configure the first target sub-pin and the second target sub-pin to implement the second transmission function.

[0068] For example, when the second electronic device is Figure 2 When the second electronic device 200 is shown, the first interface 10 and the second interface 20 can be Type-C interfaces respectively. The first target pin 11 and the second target pin 12 can be DP pins or DM pins respectively. The first target sub-pins 11a and 12a formed after splitting can continue to be used as DP pins or DM pins respectively. The first pin 10a and the second pin 10b are used to implement the first transmission function. The first connection pin 21 and the second connection pin 22 can be DP pins or DM pins respectively. The first connection sub-pins 21a and 22a formed after splitting can continue to be used as DP pins or DM pins respectively.
