[0039] Reference Figure 1 The utility model provides a computer motherboard 10, and the computer motherboard 10 includes:
[0040] Interface 110, used for connecting with electronic devices;
[0041] Processor module 120;
[0042] Display device access terminal 130, used for accessing a display device;
[0043] An input device access terminal 140 is used to access a signal output by an input device;
[0044] The signal switching circuit 150 has a first end connected to the interface 110, a second end connected to the processor module 120, a third end connected to the input device access end 140, and a fourth end connected to the display device access end 130; the signal switching circuit 150 is used to, when triggered in a first manner, conduct the path between the interface 110 and the fourth end, output the display signal output by the electronic device to the display device of the computer, and conduct the path between the third end and the interface 110, output the signal output by the input device to the electronic device.
[0045] It should be noted that in this solution, in order to operate the files in the electronic device connected to the computer motherboard 10 on the machine having the computer motherboard 10, the computer motherboard 10 transmits the display signal output by the electronic device to the display device connected to the computer motherboard 10, so that the user can browse the files or interfaces in the electronic device in the display device. In addition, in order to facilitate the operation of the files or interfaces in the electronic device, the computer motherboard 10 transmits the signal output by the connected device to the electronic device through the interface 110, thereby operating the files in the electronic device through the input device.
[0046] When the interface 110 is not connected to the electronic device, the signal switching circuit 150 connects the path between the second end and the third end to output the signal output by the input device to the processor module 120 for processing by the processor module 120. The signal switching circuit 150 also connects the path between the second end and the display device access end 130 to enable the display signal output by the processor module 120 to be output to the display device for display.
[0047] It is easy to understand that the electronic device may include a mobile phone, an IPAD, a portable host or an embedded device, etc. The model of the interface 110 is the same as the interface 110 used for connecting the electronic device. For example, when the electronic device is a mobile phone, the interface 110 may be a Type-C interface 110 or a microUSB interface 110, etc. The display device may be an LCD screen or an OLED screen, etc., which can display according to the display signal for user observation. The input device may be a keyboard, a mouse or a touch screen, etc. The processor module 120 may be a chip for data processing, such as a CPU, a GPU, and an NPU, etc. The chip may receive the signal output by the input device and perform corresponding processing, and may also output video signals, image signals, audio signals, and other signals to enable the display device to display.
[0048] The signal switching circuit 150 is used to conduct the path between the interface 110 and the fourth end, and conduct the path between the third end and the interface 110 when triggered in the first mode. When the signal switching circuit 150 is triggered in the first mode, it conducts the path between the interface 110 and the display device access end 130, so that the display signal output by the electronic device is transmitted to the display device; the display signal may include a picture signal, a video signal, an audio signal or a streaming media signal, etc. When the signal switching circuit 150 is triggered in the first mode, it also conducts the path between the interface 110 and the input end of the input device, so that the signal output by the input device is output to the electronic device.
[0049] When the signal switching circuit 150 is triggered in the first way, it represents that the interface 110 is connected to the electronic device. In one embodiment of the utility model, the interface 110 has a data terminal. When the interface 110 is connected to the electronic device, the electronic device sends a connection request through the data terminal, and the signal switching circuit 150 is connected to the interface 110, including the data terminal in the interface 110. The signal switching circuit 150 may include a voltage detection circuit for detecting the potential of the data terminal, so as to determine whether the electronic device is connected to the interface 110. It is easy to understand that when the interface 110 is not connected to the electronic device, the level of the data terminal does not change, and can be a continuous low level or a continuous high level. When the interface 110 is connected to the electronic device, since the electronic device sends a connection request through the data terminal, the level of the data terminal changes and changes between high and low levels. The signal switching circuit 150 can obtain whether the interface 110 is connected to the electronic device according to the detection result of the voltage detection circuit.
[0050] In another embodiment of the utility model, the interface 110 has a data terminal, and the data terminal is connected to the controller in the computer motherboard 10, and the controller can be a chip with a detection function; when the interface 110 is not connected to the electronic device, the data terminal can be a low level; when the interface 110 is connected to the electronic device and the electronic device sends a connection request, the potential of the data terminal changes, and can change from a low level to a high level. When the controller detects the potential change of the data terminal, it outputs a trigger signal to the signal switching circuit 150. When the signal switching circuit 150 receives the trigger signal, it conducts the path between the interface 110 and the display device access terminal 130, and conducts the path between the input device access terminal 140 and the interface 110.
[0051] When the signal switching circuit 150 is triggered in the first manner, the signal switching circuit 150 turns on the conduction between the interface 110 and the display device access terminal 130, and turns off the path between the processor module 120 and the display device access terminal 130; the signal switching circuit 150 also turns on the path between the input device access terminal 140 and the interface 110, and turns off the path between the input device access terminal 140 and the processor module 120.
[0052] The utility model discloses a computer motherboard 10, which includes: an interface 110 for connecting to an electronic device; a processor module 120; a display device access terminal 130 for accessing a display device; an input device access terminal 140 for accessing a signal output by an input device; a signal switching circuit 150, a first end of which is connected to the interface 110, a second end of which is connected to the processor module 120, a third end of which is connected to the input device access terminal 140, and a fourth end of which is connected to the display device access terminal 130; the signal switching circuit 150 is used to, when triggered in a first manner, conduct a path between the interface 110 and the fourth end, output a display signal output by the electronic device to the display device of the computer, and conduct a path between the third end and the interface 110, output a signal output by the input device to the electronic device. The utility model connects the path between the interface 110 and the display device access terminal 130 and connects the path between the interface 110 and the input device access terminal 140 when the interface 110 is connected to the electronic device through the signal switching circuit 150, so that the display device displays the file interface in the electronic device, and the input device can operate the files in the electronic device.
[0053] In one embodiment of the utility model, the signal switching circuit 150 detects the connection status between the interface 110 and the electronic device, and when the interface 110 is connected to the electronic device, the path between the interface 110 and the fourth end is connected to output the display signal output by the electronic device to the display device of the computer, and the path between the third end and the interface 110 is connected to output the signal output by the input device to the electronic device. The signal switching circuit 150 can obtain the connection status between the interface 110 and the electronic device by detecting the potential of the interface 110; wherein, in one embodiment, it can be considered that when the potential of the interface 110 changes from a low level to a high level, the interface 110 is in a connection state with the electronic device.
[0054] Reference Figure 2 In one embodiment of the present utility model, the signal switching circuit 150 includes:
[0055] A display signal switching circuit 1510, wherein a first input terminal is connected to the interface 110, a second input terminal is connected to the processor module 120, and an output terminal is connected to the display device access terminal 130; the display signal switching circuit 1510 is used to conduct the path between the interface 110 and the display device access terminal 130 when the interface 110 is connected to the electronic device, so that the display device receives the display signal output by the electronic device and displays relevant content;
[0056] The input signal switching circuit 1520 has an input end connected to the input device access end 140, a first output end connected to the processor module 120, and a second output end connected to the interface 110; the input signal switching circuit 1520 is used to conduct the path between the input device access end 140 and the second output end when the interface 110 is connected to the electronic device, and output the signal output by the input device to the electronic device.
[0057] In this embodiment, the display signal switching circuit 1510 has two input terminals, which are respectively connected to the interface 110 and the processor module 120. It is easy to understand that the interface 110 outputs the display signal of the electronic device. When the display signal switching circuit 1510 conducts the path between the first input terminal and the output terminal and cuts off the path between the second input terminal and the output terminal, the display signal switching circuit 1510 outputs the display signal output by the electronic device to the display device, so that the display device displays according to the display device and shows it to the user. It should be understood that the processor module 120 is located inside the computer motherboard 10. The processor module 120 processes tasks during the operation of the computer and generates relevant display signals. For example, when a user needs to open a certain picture, the processor can output a corresponding image signal. After receiving the display signal output by the electronic device, the display device displays relevant content according to the display signal. When the display signal switching circuit 1510 conducts the path between the second input terminal and the output terminal, the display signal switching circuit 1510 outputs the display signal output by the processor module 120 to the display device. In addition, when the interface 110 is not connected to the electronic device, the display signal switching circuit 1510 outputs the signal output by the processor module 120 to the display device.
[0058] The input signal switching circuit 1520 has two output terminals, which are respectively connected to the processor module 120 and the interface 110. It is easy to understand that when the interface 110 is not connected to the electronic device, the input signal switching circuit 1520 outputs the signal output by the input device to the processor module 120. When the interface 110 is connected to the electronic device, the input signal switching circuit 1520 conducts the path between the input terminal of the input device and the interface 110, and outputs the signal output by the input device to the electronic device, so that the user can control the electronic device through the input device and operate the files in the electronic device.
[0059] In an embodiment of the present invention, the display signal switching circuit 1510 may include an RS2227 chip, and a single-pole double-throw switch or a double-pole double-throw switch may be used to conduct the electrical circuit between the first input terminal, the second input terminal, and the output terminal of the display signal switching circuit 1510. The input signal switching circuit 1520 may use an RS2227 chip, a triode, or a MOS tube to conduct the electrical circuit between the input terminal, the first output terminal, and the second output terminal of the input signal switching circuit 1520.
[0060] Considering that in this solution, there is a situation where the protocol followed by the display signal output by the electronic device is different from the protocol of the display device input interface 110, the display device may not be able to process the display signal output by the electronic device.
[0061] Reference Figure 3 In one embodiment of the present utility model, the signal switching circuit 150 further includes:
[0062] The interface conversion module 1530 has an input end connected to the output end of the display signal switching circuit 1510, and an output end connected to the display device access terminal 130; the interface conversion module 1530 is used to detect the protocol type of the output signal of the display signal switching circuit 1510, and when the protocol is different from the interface 110 protocol of the display device, the output signal of the display signal switching circuit 1510 is converted according to the interface 110 protocol of the display device, and then output to the display device access terminal 130.
[0063] In this embodiment, the interface conversion module 1530 can obtain the protocol used by the display signal by detecting the level change of the display signal output by the electronic device, and then convert the display signal according to the interface 110 protocol of the display device; it is easy to understand that the signal encoded according to a certain protocol has a difference from the signal encoded according to other protocols; the protocol of the display signal can be obtained by finding the relevant difference points in the display signal. The difference points of each protocol after encoding can be found by the R&D personnel according to the specific encoding method of each protocol, and the determined difference points are programmed and stored in the interface conversion module 1530. The interface conversion module 1530 may include MCU, FPGA or SOC, etc. The interface conversion module 1530 may also include a decoding and encoding module, which can be used to decode the display signal and then re-encode the decoded file according to the interface 110 protocol of the display device. The interface conversion module 1530 outputs the re-encoded signal to the display device.
[0064] It should be understood that a computer may have more than one input device, such as a keyboard, a mouse, a touch screen, and so on.

[0068] In this embodiment, the input device switching module can access multiple input devices through the input device access terminal 140; in actual use, there may be a situation where multiple input devices output signals at the same time; but it should be understood that the input device switching module may include a processing chip, and the processing speed of the processing chip is sufficient to process two signals with an interval greater than the first duration; the first duration is related to the model and performance of the processing chip. In addition, when the signal interval duration of the input value of the processing chip is less than the first duration, the processing chip can use the storage device built into the processing chip to store the signal and output it to the input signal switching circuit 1520 in sequence. The input device switching circuit 1540 outputs the output signals of the multiple input devices connected to the input device access terminal 140 to the input signal switching circuit 1520 in a time-division multiplexing manner.
