[0035] Existing HUB products can only provide USB expansion functions. Users still need to rely on traditional mouse and keyboard operations to quickly save important information, switch screens, or perform other operations (such as turning off the screen and sleep mode), which brings inconvenience to users.
[0036] Based on the above problems, the USB-HUB provided in the embodiment of the present application includes a command input module, a main interface of a data expansion module and an expansion interface. When actually used, the main interface is connected to the main device, and the expansion interface is connected to the expansion device. Among them, the main device can be a computer, and the expansion device can be a mouse or a keyboard. When the user wants to operate the main device, the user operates the command input module, and the command input module outputs a first level signal to the data expansion module according to the user's operation. The data expansion module generates a first instruction according to the first level signal, and the main interface transmits the first instruction to the main device so that the main device performs a preset operation.

Only the command input module needs to be operated to enable the main device to perform the corresponding operation, thereby improving the user's work efficiency and convenience.
[0037] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0038] Figure 1 FIG. 1 shows a functional block diagram of a USB-HUB 10 provided in an embodiment of the present application. Figure 1As shown, the USB-HUB 10 includes: a command input module 101, a data expansion module 102, a main interface 103 and multiple expansion interfaces 104. The command input module 101, the main interface 103 and all the expansion interfaces 104 are electrically connected to the data expansion module 102. The main interface 103 is used to electrically connect to the main device 20, and the expansion interface 104 is used to electrically connect to the expansion device 30.
[0039] Specifically, in actual use, the main interface 103 is connected to the main device 20, and the expansion interface 104 is connected to the expansion device 30. Among them, the main device 20 can be a computer, and the expansion device 30 can be a mouse or a keyboard. When the user wants to operate the main device 20, the user operates the instruction input module 101, and the instruction input module 101 outputs a first level signal to the data expansion module 102 according to the user's operation. The data expansion module 102 generates a first instruction according to the first level signal, and the main interface 103 transmits the first instruction to the main device 20 so that the main device 20 performs a preset operation. It can be seen that the USB-HUB10 provided in the embodiment of the present application is provided with an instruction input module 101, and the instruction input module 101 can receive the user's operation, so that the user operates the main device 20. Therefore, when the user wants to quickly save important information, switch screens, or perform other operations (such as turning off the screen and sleep mode), there is no need to rely on traditional mouse and keyboard operations. Only the instruction input module 101 needs to be operated to enable the main device 20 to perform the corresponding operation, thereby improving the user's work efficiency and convenience.
[0040] Exemplarily, the main device 20 can be a computer, a microprocessor, etc. If the user wants to save the current page of the computer, the user performs a save operation. The instruction input module 101 outputs a first level signal corresponding to the save operation to the data expansion module 102 according to the user's save operation, and the data expansion module 102 generates a first instruction corresponding to the save operation according to the first level signal, and sends the first instruction corresponding to the save operation to the computer through the main interface 103, so that the computer performs the save operation.
[0041] In one embodiment of the present application, the data expansion module 102 includes a data expansion chip U1, the first end of the data expansion chip U1 is electrically connected to the main interface 103, the second end of the data expansion chip U1 is electrically connected to the instruction input module 101, and multiple third ends of the data expansion chip U1 are electrically connected to multiple expansion interfaces 104 accordingly.
[0042] Specifically, the first end of the data expansion chip U1 can be electrically connected to the main device 20 through the main interface 103, and can interact with the main device 20, that is, the data expansion chip U1 can output a first instruction to the main device 20, and can also receive a power signal and other data provided by the main device 20. The second end of the data expansion chip U1 is electrically connected to the instruction input module 101, and can receive a first level signal output by the instruction input module 101. The multiple third ends of the data expansion chip U1 are electrically connected to the multiple expansion interfaces 104 correspondingly, and can interact with multiple expansion devices 30, that is, the data expansion chip U1 can output a signal to the expansion device 30, and can also receive a signal output by the expansion device 30.
[0043] For example, Figure 2 As shown, the model of the data expansion chip U1 is BGS3510, the main interface 103 is a USB interface, and the expansion interface 104 is a USB interface or a TYPE-C interface. Among them, the UFP_DP pin, USB_DM pin, UFP_SSTX- pin, UFP_SSTX+ pin, UFP_SSRX- pin and UFP_RX+ pin of the data expansion chip U1 are all electrically connected to the main device 20 (such as a computer) through the main interface 103 (USB interface). The PWE-EN# pin, FN-A pin, FN-B pin and FN-C pin of the data expansion chip U1 are all electrically connected to the instruction input module 101, and are used to receive the first level signal output by the instruction input module 101. The DFP1 related pins, DFP2 related pins, DFP3 related pins and DFP4 related pins of the data expansion chip U1. These pins are all USB3.0 signal output pins, which can receive data output by the expansion device 30.
[0044] It should be noted that after the main device 20 is connected to the data expansion chip U1 through the main interface 103, Figure 3 The 5V adapter only shown provides the main power supply for other devices and the data expansion chip U1. The power 5V-IN supplied by the 5V adapter only terminal is electrically connected to the 20th pin of the data expansion chip U1, and the power management circuit (such as Figure 4 As shown in Figure 1, the 3.3V is output through the 21st pin of the data expansion chip U1 to provide power for other working modules of the data expansion chip U1. Figure 5 As shown, the buck chip U2 steps down 5V to 1.2V. Figure 6 The circuit shown converts 1.2V and supplies the converted voltage to the working power required by the data expansion chip U1. Figure 7For SPI communication circuit, data expansion chip U1 will provide CLK signal and select the electronic device to communicate through CS signal. Data is transmitted from data expansion chip U1 to electronic device through MOSI line and from electronic device to data expansion chip U1 through MISO line. Figure 8 It is the crystal oscillator circuit of the data expansion chip U1, used to provide a crystal oscillator for the data expansion chip U1, and electrically connected to the 44th pin and the 45th pin of the data expansion chip U1.
[0045] It should be noted that the data expansion chip U1 supports dynamic switching of power states and power management power saving modes, which can balance power consumption and performance.
[0046] In one embodiment of the present application, the instruction input module 101 includes a plurality of key units, each of which is electrically connected to the data expansion module 102, and the key unit is used to output a first level signal according to a user's operation.
[0047] Specifically, multiple button units are electrically connected to multiple pins of the data expansion chip U1. When the button units output a first level signal, the data expansion chip U1 can receive the first level signal and output a first instruction to the main device 20 through the main interface 103 according to the first level signal.
[0048] In one embodiment of the present application, the button unit includes a first resistor and an operation button, the first end of the first resistor is electrically connected to the power supply VDD, the second end of the first resistor is electrically connected to the data expansion module 102, the first end of the operation button and the fourth end of the operation button, respectively, and the second end of the operation button and the third end of the operation button are both grounded.
[0049] Specifically, Fig. 9 As shown, R29, R7, R14 and R21 are all used as the first resistor, and are all used for pull-up. When the user does not press the operation button, that is, the instruction input module 101 does not receive the preset signal, the power supply VDD, the first resistor and the ground cannot form a loop, and the first level signal received by the data expansion chip U1 is a high level signal. When the user presses the operation button, that is, the instruction input module 101 receives the preset signal, the power supply VDD, the first resistor and the ground form a loop, and the first level signal received by the data expansion chip U1 is a low level signal. After the user presses the operation button, the operation button can automatically bounce back to its original position, the power supply VDD, the first resistor and the ground cannot form a loop, and the first level signal received by the data expansion chip U1 is a high level signal. After the data expansion chip U1 receives the pulse signal converted from high level to low level and then to high level, it analyzes and outputs the first instruction to the main device 20.
[0050] For example, Fig. 9The four operation buttons in the computer can be pressed one at a time, or two or three at a time to make the computer perform different operations. For example, pressing the K1 operation button can increase the volume of the main device 20, pressing the K2 operation button can reduce the volume of the main device 20, pressing the K3 operation button can mute the main device 20, pressing the K4 button can make the main device 20 play / pause the video, pressing the K1 operation button and the K2 operation button at the same time can make the main device 20 take a screenshot with one click, and other buttons can be pressed at the same time to make the main device 20 sleep, wake up, go to the desktop with one click, etc. Therefore, the USB-HUB10 provided in this application can enable users to quickly complete processing with one click, save working time, improve efficiency, and provide convenience for users.
[0051] In one embodiment of the present application, the key unit also includes a second resistor and a light-emitting diode, the first end of the second resistor is electrically connected to the data expansion module 102, the second end of the second resistor is electrically connected to the anode of the light-emitting diode, and the cathode of the light-emitting diode is grounded.
[0052] Specifically, Fig.10 As shown, R20, R6, R12 and R19 are all used as the second resistors, and are all used to limit the current to prevent the current transmitted to the light-emitting diode from being too large, which may damage the light-emitting diode. The light-emitting diode is used to emit light to indicate that the user is operating the operation button. When the user presses the operation button, the power supply VDD, the second resistor, the light-emitting diode and the ground form a loop, and the light-emitting diode is powered and emits light.
[0053] For example, if the user presses the K1 operation button, the power supply VDD, R29, R20, the light-emitting diode LED1 and the ground form a loop, and the light-emitting diode LED1 is powered to emit light to indicate that the user is operating the operation button.
[0054] The present application also discloses a communication system, such as Fig.11 The communication system includes a main device 20, multiple expansion devices 30 and the above-mentioned USB-HUB10, the main device 20 is electrically connected to the main interface 103 in the USB-HUB10, and the multiple expansion devices 30 are electrically connected to the multiple expansion interfaces 104 in the USB-HUB10.
[0055] Specifically, in actual use, when the user wants to operate the main device 20, the user operates the instruction input module 101, and the instruction input module 101 outputs a first level signal to the data expansion module 102 according to the user's operation. The data expansion module 102 generates a first instruction according to the first level signal, and the main interface 103 transmits the first instruction to the main device 20, so that the main device 20 performs a preset operation. It can be seen that the USB-HUB 10 provided in the embodiment of the present application is provided with an instruction input module 101, and the instruction input module 101 can receive the user's operation, so that the user can operate the main device 20. Therefore, when the user wants to quickly save important information, switch screens, or perform other operations (such as turning off the screen and sleep mode), there is no need to rely on traditional mouse and keyboard operations. Only the instruction input module 101 needs to be operated to enable the main device 20 to perform the corresponding operation, thereby improving the user's work efficiency and convenience.
[0056] In one embodiment of the present application, the communication system further includes a display module, which is electrically connected to the data expansion module 102 in the USB-HUB 10 .
[0057] Specifically, the display module allows the user to interact with the main device 20 through the command input module 101 or other input devices (such as a keyboard, a touch screen, etc.) to input commands and view data. The display module is also used to display the working status, operation feedback, and data processing results of the main device, providing the user with real-time information.
