[0039] In the embodiment of the present application, when the first external device 12 is connected to the electronic device 11, if the electronic device 11 is restarted or powered on, the first external device 12 is reset. During the reset process, when the electronic device 11 has not completed initialization, the first external device 12 is not powered. After the electronic device 11 completes initialization, the first external device 12 is powered, thereby completing the reset of the first external device 12.

[0040] Figure 1B This is another scenario diagram of the reset method provided in the embodiment of the present application. Figure 1B The scene includes an electronic device 11, a first external device 12, and a second external device 14. The electronic device 11 is connected to the first external device 12, and the first external device 12 is connected to the second external device 14.

[0041] Figure 1B In the embodiment, the electronic device 11 and the first external device 12 can be connected through the above Figure 1AThe figure only illustrates the connection method of connecting through the TYPE-C connecting line 13.

[0042] Figure 1B In the embodiment, a first USB interface is provided on the first external device 12, and a second USB interface is provided on the second external device. The first USB interface and the second USB interface can be TYPE-C interfaces, or other USB interfaces, such as TYPE-A interfaces, TYPE-B interfaces, etc., which are not limited in the embodiment of the present application. The second external device 14 can be directly inserted into the first external device 12; or, the second external device 14 and the first external device 12 are connected via a USB cable 15.

[0043] Please refer to Figure 1B , the first external device 12 is powered by the electronic device 11, and the second external device 14 is powered by the first external device 12.

The second external device includes a microphone 141 and a camera 142, which are respectively inserted into different USB interfaces of the first external device 12.

[0045] Figure 1C In the embodiment, when the electronic device is restarted or turned on, the first external device 12, the microphone 141 and the camera 142 are reset. During the reset process, when the electronic device 11 has not completed initialization, the first external device 12 is not powered on, thereby cutting off the power to the microphone 141 and the camera 142. After the electronic device 11 completes initialization, the first external device 12 is powered on, thereby causing the first external device 12 to power the microphone 141 and the camera 142. In this way, each time the electronic device 11 is started, the first external device 12, the microphone 141 and the camera 142 are reset.

[0046] Above Figure 1A to Figure 1C In the illustrated scenario, the electronic device 11 includes a main body and a mainboard disposed in the main body, and the mainboard has a first TYPE-C interface. Based on the mainboard of the electronic device, when the electronic device is started or restarted, all external devices (including the first external device and the second external device) are powered off and then powered on again to ensure stable operation of each external device.

[0047] Next, the mainboard of the electronic device 11 is described in detail. Figure 2A-2C .

[0048] Figure 2A This is a schematic diagram of the structure of the motherboard provided in the embodiment of the present application. Figure 2A The motherboard 200 provided in the embodiment of the present application includes: a processing module 21, a signal conversion module 22, a multiplexing module 23, a first TYPE-C interface 24 and a power supply module 25. The processing module 21 is connected to the signal conversion module 22, the signal conversion module 22 is connected to the power supply module 25 and the multiplexing module 23, the power supply module 25 is connected to the first TYPE-C interface 24, the multiplexing module 23 is connected to the first TYPE-C interface 24, the first TYPE-C interface 24 is used to connect to the second TYPE-C interface, the second TYPE-C interface is the TYPE-C interface of the first external device, the first external device is a device powered by the motherboard 200, that is, the first external device is a device that draws power from the motherboard 200.

[0049] The first TYPE-C interface is also called a full-function TYPE-C interface, which has power delivery (PD) function and video data transmission function, and is compatible with the transmission of USB2.0 signals, USB3.0 signals, etc. Through the PD function, the mainboard 200 can supply power to the first external device. The mainboard 200, as a master device, transmits voltage to the first external device through the first TYPE-C interface, thereby realizing power supply to the first external device, which is also called a slave device.

[0050] The front and back sides of the first TYPE-C interface are the same, so the first external device can be inserted in both directions and has a small size. The first TYPE-C interface has a total of 24 pins, and the definition of each pin is as follows Figure 3 shown.

[0051] Figure 3 This is a pin definition diagram of the first TYPE-C interface of the motherboard provided in the embodiment of the present application. Figure 3The first TYPE-C interface of the mother socket includes 24 pins, including side A and side B. After flipping side A and side B, the definition order of each pin remains the same. Figure 3 A1 to A12 in the figure are GND, TX1+, TX1-, VBUS, CC1, D+, D-, SBU1, VBUS, RX2-, RX2+, GND respectively; the 12 pins on the B side are as follows Figure 3 B12 to B1 in the figure are GND, RX1+, RX1-, VBUS, SBU2, D-, D+, CC2, VBUS, TX2-, TX2+, and GND respectively.

[0052] Among them, A1, A12, B1 and B12 are all ground pins, A4, A9, B4 and B9 are all cable bus power (Cable Bus Power, VBUS) pins, and the power supply and ground each have 4 pins, which are specifically used for power supply and grounding respectively.

[0053] A2, A3, B10 and B11 as well as B2, B3, A10 and A11 form 4 pairs of TX / RX breakout lines, providing one or more channels, such as providing two channels of ultra-speed data links, to achieve bidirectional broadband, such as achieving a bidirectional bandwidth of up to 20 Gbps.

[0054] The two groups of pins A6 and A7 as well as B6 and B7 use D+ and D- signals to be compatible with pre-USB standard data, such as USB2.0.

[0055] The A8 and B8 pins are auxiliary pins. Auxiliary signals (Side band use, SUB) 1 and SBU2 are only used in some specific transmission modes, such as analog audio mode.

[0056] A5 and B5 pins are two channel configuration (CC) signal pins, CC1 and CC2 are two key pins for identifying the insertion direction. For example, it can be achieved by monitoring whether CC1 or CC2 of the first TYPE-C interface has a pull-down resistor, which is not limited in the embodiments of the present application.

[0057] When the insertion direction is the forward insertion direction, CC1 of the first TYPE-C interface is connected to CC1 of the male connector, and CC2 of the first TYPE-C interface is connected to CC2 of the male connector. When the insertion direction is the reverse insertion direction, CC1 of the first TYPE-C interface is connected to CC2 of the male connector, and CC2 of the first TYPE-C interface is connected to CC1 of the male connector.

[0058] Please refer to Figure 3One function of the multiplexing module 23 is to determine the insertion direction of the second TYPE-C interface, that is, whether the insertion direction of the second TYPE-C interface is a forward insertion direction or a reverse insertion direction. The multiplexing module 23 includes a multiplexer (MUX) and the like.

[0059] In the embodiment of the present application, resetting the external device (including the first external device and the second external device) includes two stages: before the mainboard initialization is completed and after the mainboard initialization is completed.

[0060] Phase 1: Before the motherboard initialization is completed.

[0061] The processing module 21 is used to control the signal conversion module 23 to send a first control signal to the power supply module 25 after detecting the power-on signal and before the mainboard 200 is initialized, so as to trigger the power supply module 25 to stop supplying power to the first TYPE-C interface 24.

[0062] Please refer to Figure 2A The processing module 21 at least includes a system on chip (SoC). After the user restarts or starts the electronic device, the processing module 21 detects the power-on signal and initializes the mainboard 200. At the same time, the processing module 21 sends a low-level signal to the signal conversion module 22 through the general-purpose input / output (GPIO) port, which is also called a reset signal.

[0063] After receiving the low-level signal, the signal conversion module 22 sends a first control signal to the power supply module 25. The first control signal is also a low-level signal, which is used to trigger the power supply module 25 to stop supplying power to the first TYPE-C interface 24. After receiving the first control signal, the power supply module 25 stops supplying power to the first TYPE-C interface 24, thereby powering off the first TYPE-C interface 24, thereby powering off the first external device. When there are multiple first external devices, each first external device is powered off.

[0064] If the first external device is also connected to a second external device, and the second external device is powered by the first external device, then the second external device is also powered off due to the first external device being powered off. Even if the first external device is connected to multiple second external devices, all of the multiple second external devices are powered off.

[0065] The second stage: after the mainboard initialization is completed.

[0066] The processing module 21 is further used to control the signal conversion module 23 to send a second control signal to the power supply module 25 after the mainboard 200 is initialized, so as to trigger the power supply module 25 to supply power to the first TYPE-C interface 24 according to the insertion direction.

[0067] Please refer to Figure 2A After the motherboard 200 is initialized, the processing module 21 sends a high-level signal to the signal conversion module 22 through the GPIO. After receiving the high-level signal, the signal conversion module 22 is powered on and initialized, and sends a second control signal to the power supply module 25. The second control signal is a high-level signal, which is used to trigger the power supply module 25 to supply power to the first TYPE-C interface 24. After receiving the second control signal, the power supply module 25 is powered on and initialized, and supplies power to the first TYPE-C interface 24 to realize power supply to the first external device. When there are multiple first external devices, each first external device is powered on.

[0068] If the first external device is also connected to the second external device, and the second external device is powered by the first external device, then since the first external device is powered by the mainboard, the second external device is also powered by the first external device. Even if the first external device is connected to multiple second external devices, the multiple second external devices are all powered by the first external device. By default, the signal conversion module 22 sends an I2C signal to the power supply module 25, and the I2C signal is used to instruct the power supply module 25 to output a voltage of 5V. After receiving the I2C signal, the power supply module 25 outputs a pulse (pulse width modulation, PWM) corresponding to the 5V voltage to the first TYPE-C interface 24. The first TYPE-C interface 24 provides a 5V supply voltage to the first external device.

[0069] The mainboard provided in the embodiment of the present application includes a processing module, a signal conversion module, a multiplexing module, a power supply module and a first TYPE-C interface. Among them, the reset module is used to determine the insertion direction of the second TYPE-C interface. During the reset process, after the mainboard detects the power-on signal and before completing the initialization, the processing module controls the signal conversion module to send a first control signal to the power supply module to trigger the power supply module to stop supplying power to the first TYPE-C interface; after the mainboard completes the initialization, the processing module controls the signal conversion module to send a second control signal to the power supply module to trigger the power supply module to supply power to the first TYPE-C interface according to the insertion direction. With this solution, when the electronic device is turned on or restarted, the external device is reset, that is, the external device completes a power-off and power-on operation to ensure that the external device runs stably after the electronic device is started.

[0070] Figure 2B This is another structural diagram of the motherboard provided in the embodiment of the present application. Figure 2B The processing module 21 includes a bridge unit 211 and a processing unit 212. The bridge unit 211 at least includes a platform controller hub (Platform Controller Hub, PCH), also known as a south bridge chip. After the bridge unit 211 detects the power-on signal and before the motherboard initialization is completed, the bridge unit 211 sends a low-level signal to the signal conversion module 22 to trigger the signal conversion module 22 to send a first control signal to the power supply module. During the motherboard initialization process, the processing unit 212 sends a High Definition Multimedia Interface (HDMI) signal to the signal conversion module 22.

[0071] After receiving the HDMI signal, the signal conversion module converts it into a display port (DP) signal. Afterwards, the signal conversion module 22 sends the DP signal to the first external device through the multiplexing module 23 and the first TYPE-C interface 24 for display by the first external device. For example, if the first external device is a display, an all-in-one machine with a display screen, etc., the first external device displays the screen during the startup process of the electronic device. When the electronic device is powered on, the first external device displays the desktop of the electronic device.

[0072] In this solution, the processing module includes a bridge unit and a processing unit. The bridge unit is responsible for sending a low-level signal or a high-level signal to the signal conversion module during the reset process to trigger power off or power on the first TYPE-C interface. The processing unit is responsible for sending HDMI signals, etc., with clear division of labor and high reliability.

[0073] Figure 2C This is another structural diagram of the motherboard provided in the embodiment of the present application. Figure 2C , the processing module 21 is connected to the signal conversion module 22 to form a first path 26. After the processing module 21 detects the power-on signal, it sends a low-level reset signal to the signal conversion module 22 through the first path 26 to control the signal conversion module 22 to send a first control signal to the power supply module 25. After the mainboard completes initialization, the processing module 21 sends a high-level signal to the signal conversion module 22 through the first path 26.

[0074] The processing module 21 is connected to the multiplexing module 23 to form a second path 27, and the second path 27 is used to transmit USB3.0 signals. The processing module 21 is connected to the first TYPE-C interface 24 to form a third path 28, and the third path 28 is used to transmit USB2.0 signals.

[0075] Please refer to Figure 1B and Figure 1CWhen the electronic device is connected to the first external device and the first external device has a USB interface for inserting the second external device, if the second external device is connected to the first external device, since the second external device is often a USB device, such as a USB flash drive, a mouse, a microphone, a camera, etc., it is necessary to exchange data with the electronic device through the second path 27 or the third path 28.

[0076] By adopting this solution, a first path is set between the bridge unit and the signal conversion module, a second path is set between the bridge unit and the multiplexing module, and a third path is set between the bridge unit and the first TYPE-C interface, so as to facilitate the transmission of reset signals, USB2.0 signals, and USB3.0 signals, thereby improving the use range of electronic equipment.

[0077] Please refer to Figure 2C Optionally, the power supply module 25 includes an interconnected control unit 251 and a buck-boost unit 252, wherein the control unit 251 is connected to the signal conversion module 22, and the buck-boost unit 252 is connected to the first TYPE-C interface 24, wherein: the control unit 251 is used to receive the power supply voltage from the signal conversion module 22, and send a pulse corresponding to the power supply voltage to the buck-boost unit 252. The buck-boost unit 252 is used to perform buck-boost processing on a preset voltage according to the pulse to obtain the power supply voltage, so that the first TYPE-C interface 24 provides the power supply voltage for the first external device.

[0078] Exemplarily, by default, after the motherboard is initialized, the signal conversion module 22 sends a second control signal to the control unit 251, so that the power supply module 25 is powered on and initialized. By default, the signal conversion module 22 sends an I2C signal to the control unit 251, indicating that the preset voltage is 5V. After receiving the I2C signal, the control unit 251 sends a PWM corresponding to 5V to the buck-boost unit 252, so that the power supply module provides a 5V voltage to the first TYPE-C interface 24, and then the first TYPE-C interface 24 provides a 5V power supply voltage to the first external device.

[0079] However, there are many types of first external devices, and different first external devices have different power supply voltages. Therefore, the mainboard 200 obtains the power supply voltage of the first external device through the CC pin of the first TYPE-C interface 24, for example, 20V. Afterwards, the signal conversion module 22 sends an I2C signal to the control unit 251, indicating that the power supply voltage is 20V. After receiving the I2C signal, the control unit 251 sends a PWM corresponding to 20V to the buck-boost unit 252. The buck-boost unit 252 boosts the preset 5V voltage to obtain a 20V voltage and provides it to the first TYPE-C interface 24, thereby enabling the first TYPE-C interface 24 to provide a 20V power supply voltage to the first external device.

[0080] By adopting this solution, the electronic device obtains the power supply voltage of the first external device through the first TYPE-C interface, and controls the voltage of the first TYPE-C interface provided by the power supply module according to the power supply voltage, so that the first TYPE-C interface can supply power to various types of first external devices. It is highly practical and the solution is simple.

[0081] Optionally, in the above embodiment, the first external device is any one of the following devices: a display supporting a TYPE-C interface, an all-in-one machine supporting a TYPE-C interface, and a screenless device supporting a TYPE-C interface, wherein the all-in-one machine is provided with a USB interface for inserting a second external device, and the second external device is a device powered by the first external device. Screenless devices include devices that require power, such as a mouse, a microphone, a camera, a USB flash drive, and a power bank.

[0082] It is understandable that when the first external device is a power bank waiting for charging, since the device to be charged has a battery, etc., resetting the first external device does not mean: triggering the first external device to shut down and then restart. Instead, it means: when the electronic device starts or restarts, stop supplying power to the power bank and then supply power to the power bank so that the power bank can charge.

[0083] When the first external device is a camera, a mouse, an all-in-one computer, etc., since it has no battery, resetting the first external device means: triggering the first external device to shut down and then restart.

[0084] By adopting this solution, the first external device is diverse to meet the needs of different scenarios, thereby achieving the purpose of improving the applicable scenarios of the electronic device.

[0085] In the above Figure 1A-Figure 1C The scenes shown and Figure 2A-2C Based on the main board shown, the present application embodiment also provides a reset method. For example, please refer to Figure 4 , Figure 4 : is a flowchart of a reset method provided by an embodiment of the present application. This embodiment includes:

[0086] 401. After detecting a power-on signal and before the mainboard is initialized, stop supplying power to the first TYPE-C interface;

[0087] 402. After the mainboard is initialized, power is supplied to the first TYPE-C interface so that the first TYPE-C interface supplies power to a first external device.

[0088] Wherein, a second TYPE-C interface is provided on the first external device, and the first TYPE-C interface is connected to the second TYPE-C interface.

[0089] The specific implementation process and beneficial effects can be found in the description of the above-mentioned mainboard embodiments, which will not be repeated here.

[0090] Optionally, in the above embodiment, after the mainboard is initialized, the electronic device obtains the power supply voltage of the first external device through the first TYPE-C interface while supplying power to the first TYPE-C interface; and controls the first TYPE-C interface to output the power supply voltage to power the first external device.

[0091] For example, please refer to Figure 2C , the mainboard 200 obtains the power supply voltage of the first external device through the CC pin of the first TYPE-C interface 24. Afterwards, the signal conversion module 22 sends an I2C signal to the control unit 251 to indicate the power supply voltage. After receiving the I2C signal, the control unit 251 sends a PWM corresponding to the power supply voltage to the buck-boost unit 252. The buck-boost unit 252 boosts the preset 5V voltage to obtain the power supply voltage and provides it to the first TYPE-C interface 24, so that the first TYPE-C interface 24 outputs the power supply voltage to the first external device.

[0092] By adopting this solution, the power supply voltage of the first external device is obtained, and the voltage provided to the first TYPE-C interface by the power supply module is controlled according to the power supply voltage, so that the first TYPE-C interface can supply power to various types of first external devices. It is highly practical and the solution is simple.

[0093] Optionally, in the above embodiment, after the mainboard is initialized and power is supplied to the first TYPE-C interface, the electronic device further configures the interface mode of the first TYPE-C interface and transmits the DP signal and the USB signal according to the interface mode.

[0094] For example, the first TYPE-C interface has both power transmission and video data transmission functions. It is also compatible with USB2.0 signal, USB3.0 signal, etc. Figure 1AIf the first external device is a USB flash drive, a mouse, etc. that supports the TYPE-C function, the USB signal generated by the first external device is transmitted through the second path or the third path mentioned above.

[0095] Please refer to Figure 1B and Figure 1C , USB2.0 signals and USB3.0 signals are generated by the connection between the second external device and the first external device. For example, the first external device is an all-in-one machine with a display screen, and the all-in-one machine has multiple USB interfaces, and the second external device such as a microphone and a mouse is inserted into the USB interface. At this time, the electronic device configures the interface mode of the first TYPE-C interface, and transmits the DP signal and the USB signal according to the interface mode. For example, the interface mode includes mode A and mode B. Mode A configures a 2-channel display interface for the first TYPE-C interface to transmit the DP signal, and configures a 1-channel USB3.0 interface to transmit the USB3.0 signal. Mode B configures a 2-channel display interface for the first TYPE-C interface to transmit the DP signal, and configures a 2-channel USB3.0 interface to transmit the USB3.0 signal.

[0096] By adopting this solution, the DP signal and the USB signal are multiplexed on the first TYPE-C interface, which can cope with more scenarios and improve the use range of electronic devices.
