[0064] The multi-functional docking station controller of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 11 As shown, the multi-functional docking station controller provided according to the embodiment of this utility model includes a power module 10, a main control module 11, a USB expansion module 12, a light strip control module 13, a PD fast charging module 14, a voice recognition module 15, and a human body sensing module 16.

[0066] Specifically, the power module 10 is used to supply power to various circuit modules. For example, the power module 10 may include a DC-DC converter module and an IDO voltage regulator module. The DC 12V input is converted to DC 5V by the DC-DC converter module, and the DC 5V is converted to DC 3V by the IDO voltage regulator module. This allows for the supply of DC power at different voltages, such as 12V, 5V, and 3V, to meet the power supply needs of various circuit modules. For example, 12V supplies power to the PD fast charging module 14, 5V supplies power to the USB expansion module 12 and the LED strip control module 13, and 3V supplies power to the main control module 11, etc.

[0067] The main control module 11 is used to control and manage the USB expansion module 12, the light strip control module 13, the PD fast charging module 14, the voice recognition module 15, and the human body sensing module 16. For example, the main control module 11 can use the CH585M chip, a high-performance wireless MCU chip that integrates BLE Bluetooth 5.4, high-speed USB 2.0, and NFC near-field communication functions, meeting the needs of smart peripheral application scenarios.

[0068] The USB expansion module 12 is connected to the power module 10 and the main control module 11 to expand to multiple USB ports. For example, the USB expansion module 12 integrates two CH334R chips, supports up to 6 USB ports (e.g., Type-A and Type-C), which can be connected to external devices. It has a built-in PD protocol control chip and supports multiple voltage combinations such as 5V, 9V, and 12V.

[0069] The LED strip control module 13 is connected to the power module 10 and the main control module 11 to control the LED strip lighting. Using this module 13, the brightness, color temperature, and dynamic effects of the LED strip can be controlled and adjusted, such as achieving dynamic effects like screen color synchronization or music rhythm synchronization.

[0070] The PD fast charging module 14 is connected to the power module 10 and the main control module 11 to fast charge external devices. This PD fast charging module 14 can be used to quickly charge external devices such as mobile phones and tablets.

[0071] The voice recognition module 15 is connected to the main control module 11 to collect and recognize voice commands, and to control one or more of the light strip control module 13, USB expansion module 12, and PD fast charging module 14 via voice commands through the main control module 11. This voice recognition module 15 does not rely on a network, enabling offline voice control. For example, it parses user intent through a built-in command set and maps commands such as "turn on the light strip," "turn off all USB ports," or "start fast charging" to the corresponding module's control commands, achieving natural voice-based human-computer interaction.

[0072] The human body sensing module 16 is connected to the main control module 11 to collect human body signals. When the human body sensing module 16 detects no human body signal, the main control module 11 controls the lighting control module to turn off the LED light strip. The main control module 11 can read the presence status of a human body from the human body sensing module 16. When no one is detected in the environment for a preset time, the main control module 11 will generate a command to turn off the light strip and disconnect the USB interface; when a person is detected approaching again, the light strip and USB interface can be automatically restored according to a preset time, improving user experience and saving power. The human body sensing module 16 can be, but is not limited to, a millimeter-wave radar module, with a sensing range of 0.3 to 6 meters, and has both motion and static recognition capabilities.

[0073] The multi-functional docking station controller provided in this embodiment integrates a USB expansion module 12, an LED strip control module 13, and a PD fast charging module 14, enabling simultaneous expansion of multiple USB ports, intelligent control of LED strips, and fast charging of external devices. Simultaneously, through a voice recognition module 15 connected to the main control module 11, user voice commands can be collected and recognized for voice control of USB expansion, LED strip brightness, and PD fast charging. Combined with a human body sensing module 16 that detects human signals in real time, the LED strip automatically turns off when no one is in the environment. This provides a variety of functions, including rich interfaces, power supply, lighting effects, and voice interaction, in various scenarios such as e-sports rooms, smart offices, and voice interaction, meeting different needs in these scenarios and realizing the expansion and management of intelligent desktop devices.

[0074] Reference Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the multi-functional docking station controller further includes a PC power on / off control module 17, which is connected to the main control module 11 and is used to control the computer power supply to turn on or off according to voice commands from the main control module 11. Exemplarily, the PC power on / off control module 17 can be a relay or a low-voltage MOSFET switching device to simulate the power button operation on the front panel of the chassis, thereby realizing the on / off operation of the computer power supply.

[0075] When the main control module 11 receives a "power on" or "power off" command from the voice recognition module 15, it sends a corresponding high-level or low-level control signal to the PC power on / off control module 17, driving the relay to short-circuit the Power pin. After a preset time (e.g., 200 milliseconds) of simulated pressing, the pin returns to the open state, completing a standard key operation, thus realizing voice power on or power off control of the computer.

[0076] By integrating a PC power on / off control module 17 into the multi-functional docking controller, and cooperating with the voice recognition module 15 and the main control module 11, this embodiment realizes voice control and key simulation of computer power supply, and has soft shutdown and forced power-off functions, effectively improving the user's ease of operation and intelligent management level.

[0077] Reference Figure 3 As shown, in one embodiment of this utility model, the LED strip control module 13 includes a data selector, a first USB interface, and an LED strip driver module. The data selector has a data source selection terminal, multiple data input terminals, and multiple control signal output terminals. This data selector can use a 74HCT157D chip, a 4-channel data selector, with data source selection terminals LED_SEL and EX_LED_SEL, a data input terminal LEDx_DAT, and a control signal output terminal LEDx_DAT_OUT.

[0078] The data terminal of the first USB interface is connected to the control signal output terminal, and the power terminal of the first USB interface is connected to a DC power supply. The LED strip driver module is connected to the USB interface and operates according to the control signal output from the control signal output terminal.

[0079] The data source selection terminal is connected to the main control module 11 to determine the source of the LED strip control signal. Multiple data input terminals are connected to the main control module 11 to receive external or internal data, thereby enabling different control methods. For example, external data such as music or animation can be used to achieve synchronized lighting effects, or pre-stored internal data can be used to achieve predetermined lighting effects. Multiple USB control signal output terminals are connected to multiple LED strip driver modules for independent control of each module.

[0080] In this embodiment, multiple light strips are coordinated and controlled through a data selector and independent channels. Control signals sent via an external interface or the main control module 11 can control the light strips to achieve dynamic color changes, brightness adjustment, zone control, and dynamic effects, making it suitable for smart home, e-sports, and other scenarios.

[0081] Reference Figure 3 As shown, in one embodiment of this utility model, the data terminal of the first USB interface is connected to the control signal output terminal through the forty-first resistor R41, and the data terminal of the first USB interface is grounded through the steady-state diode D15.

[0082] In this embodiment, the forty-first resistor R41 and the steady-state diode D15 form an ESD protection impedance matching circuit. The forty-first resistor R41 is used for input impedance matching of the high-speed differential signal and provides necessary current limiting between the signal source and the LED strip driver module, effectively suppressing high-frequency reflections and ensuring signal integrity. The steady-state diode D15 effectively suppresses in-band surges and electrostatic discharge (ESD). Therefore, this embodiment significantly enhances the system's protection against ESD, surges, and overvoltage while maintaining high-speed signal integrity, effectively ensuring the safe operation of the LED strip driver module and data selector, and improving the anti-interference capability and overall reliability of the docking station controller.

[0083] Reference Figure 4 As shown, in one embodiment of this utility model, the PC power on / off control module 17 includes a second USB interface USB6, an optocoupler U18, a transistor Q1, a relay U43, and a button KEY3.

[0084] The second USB port, USB6, is used to provide power signals to the computer.

[0085] Optocoupler U18 is used to isolate external control signals from the computer's power button signal. The collector and emitter of optocoupler U18 are respectively connected to the positive and negative power supply terminals of the second USB interface USB6. The anode of optocoupler U18 is connected to the DC power supply through the thirtieth resistor R30.

[0086] The base of transistor Q1 is connected to the main control module 11 to receive external control signals. The collector of transistor Q1 is connected to the cathode of optocoupler U18, and the emitter of transistor Q1 is grounded.

[0087] The driving end of relay U43 is connected to the cathode of optocoupler U18, and the output end of relay U43 is connected to the positive and negative power supply terminals of the second USB interface USB6, respectively, to simulate power-on or power-off actions and realize power-on or power-off.

[0088] Button KEY3 is connected to another set of positive and negative power terminals of the second USB interface USB6, so as to directly trigger the computer to turn on or off.

[0089] During operation, the voice recognition module 15 recognizes the power-on command, and the main control module 11 outputs a control signal to the base PC_ON of transistor Q1 according to the power-on command, turning on transistor Q1. After transistor Q1 turns on, the LED at the input terminal of optocoupler U18 lights up, and the phototransistor turns on. The output trigger signal of optocoupler U18 reaches the relay driver terminal ENB. After receiving the trigger signal output by optocoupler U18, the driver terminal ENB of relay U43 closes the internal switch of relay U43. The closing of relay U43 simulates the action of the PC power-on button, shorting the positive and negative terminals PC_POWER+ and PC_POWER- on the second USB interface USB6, sending a power-on signal to the motherboard, and realizing the computer power-on control.

[0090] In addition, users can also manually power on the device by pressing the physical button KEY3 to directly short-circuit the positive and negative power terminals PC_POWER+ and PC_POWER- on the second USB port USB6.

[0091] In this embodiment, the isolation and conversion of the PC power-on signal are achieved through the cooperation of optocoupler U18, relay U43 and transistor Q1. It can automatically power on by accepting external control signals or manually power on by physical buttons, which has both reliability and flexibility.

[0092] Reference Figure 1 and Figure 8 As shown, in one embodiment of this utility model, the multi-functional docking station controller further includes an RF receiving module 18, which is connected to the main control module 11 and is used to receive remote control signals from an external remote controller. The main control module 11 then controls one or more of the LED strip control module 13, USB expansion module 12, and PD fast charging module 14 via the remote control.

[0093] In practical use, users can configure a remote control to operate the desktop docking station from a range of several meters. Users can quickly manage multiple interfaces, lighting effects, and other peripherals connected to the docking station controller using commands such as "one-click to turn off the lights" without having to physically go to the controller. This method is particularly suitable for noisy environments or situations where voice recognition is inconvenient, improving versatility and ease of use. It provides users with a reliable and responsive control method, enriches the docking station's interaction methods, and significantly enhances the product's user experience and adaptability in various scenarios.

[0094] Reference Figure 9 As shown, in one embodiment of this utility model, the PD fast charging module 14 includes a buck converter module, a protocol control chip, a control switch module, and an output port.

[0095] The input terminal of the buck converter module is connected to the power supply module 10 and is used to step down the input DC power for output.

[0096] The input terminal of the protocol control chip is connected to the output terminal of the buck converter module, and is used to communicate with external devices and adjust the output voltage according to the fast charging protocol.

[0097] The input terminal of the control switch module is connected to the main control module 11, and the control terminal of the control switch module is connected to the protocol control chip, which is used to turn on the buck converter module in fast charging mode.

[0098] The output port is connected to the output terminal of the protocol control chip and is used to provide a fast charging power source to external devices.

[0099] During operation, the input terminal receives high-voltage DC power (e.g., 12V), which enters the buck converter module through fuse F4 and a filter capacitor. The protocol control chip U13 initializes, handshakes with the external device, and negotiates the fast charging protocol. When the main control module 11 detects the external device connection and the protocol control chip has successfully completed the handshake, the main control module 11 outputs a corresponding control signal to the control switch module, driving it to conduct, thereby enabling the buck converter module and allowing power output through the PDEN pin. If the handshake fails or no device is connected, the main control module 11 can immediately pull down or turn off the control switch module, cutting off the power supply to the buck converter module. The protocol control chip adjusts the feedback signal on the PD_FB pin according to the fast charging protocol requirements. The buck converter module U12 adjusts the output voltage based on the feedback signal. The adjusted voltage is provided to the external device through the output port USB7.

[0100] Through its workflow, the PD fast charging module achieves a high degree of coordination with the main control module 11 and other sub-modules. It can quickly provide high-power charging when needed and disconnect in time under no-load or abnormal conditions without additional external intervention. This effectively reduces system energy consumption, improves charging efficiency, and ensures the overall safety and stability of the system.

[0101] This embodiment integrates step-down conversion, protocol control, and intelligent switch management, enabling automatic handshake and voltage regulation under various USB fast charging protocols. Combined with the unified scheduling of the main control module 11, it achieves dynamic control and safety protection of fast charging output, greatly improving charging efficiency while taking into account compatibility, safety, and energy saving.

[0102] Reference Figure 11 As shown, in some embodiments of this utility model, the multi-functional docking station controller also includes a desktop riser interface 19 for connecting a desktop riser to extend desktop devices.

[0103] Through the aforementioned desktop riser interface 19 design, this embodiment not only enables the docking station controller to support a wider range of desktop peripherals, but also allows the main control module 11 to centrally manage and dynamically schedule the riser devices while ensuring power safety and signal integrity. This greatly enhances the scalability and scenario adaptability of the docking station controller, providing flexible and customized applications for desktop environments such as e-sports and smart offices.
