[0032] This application provides a docking station, also known as a port replicator, which is an external device designed specifically for smart devices. By replicating or even expanding the ports of a smart device, the docking station allows for convenient one-stop connection between the smart device and multiple different types of external devices (such as power adapters, network cables, mice, external keyboards, printers, and external display devices). Multiple ports expanded via the docking station can operate simultaneously.

[0033] The present application will be further described below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an expansion dock provided in one embodiment of the present application. The expansion dock includes a housing 100 and a circuit board 200.

[0035] The housing 100 is provided with a screen lock operation module 110, an indicator module 120 and an external port module 130 for establishing a communication connection with the source device 11;

[0036] The circuit board 200 is located inside the housing 100. The circuit board 200 is equipped with a main control chip 210. The main control chip 210 is electrically connected to the screen lock operation module 110, the indicator module 120 and the external port module 130 respectively. The main control chip 210 is used to control the source device 11 to enter the screen lock state through the external port module 130 when the screen lock operation module 110 is touched, and to control the indicator module 120 to work.

[0037] As can be understood, a docking station is a device used to expand the functionality of external electronic devices. That is, it connects external electronic devices through specific interfaces, thereby providing additional ports and functions for the external electronic devices. For example, a docking station can provide multiple ports for electronic devices to connect more external devices, such as mice, keyboards, monitors, printers, etc. It can also enable multi-screen display or high-definition video output through video data ports. It can also charge external electronic devices and provide a more stable network connection, etc.

[0038] It is understood that the source device 11, also known as the uplink device, can include electronic devices with displays such as laptops, tablets, or mobile phones in practical applications; this application does not limit the specific type of the source device 11.

[0039] In this embodiment, the external port module 130 is used to establish a communication connection with the source device 11. Therefore, the external port module 130 may include ports such as USB-C, USB-A, and Type-C, through which a communication connection can be established with the source device 11. In addition, the external port module 130 may also include video ports such as HDMI, DisplayPort, VGA, and DVI, as well as Ethernet ports for providing wired network connections, audio ports, power ports, Thunderbolt ports, and dedicated ports such as eSATA and FireWire for connecting specific devices.

[0040] In this embodiment, the screen lock operation module 110 may include a pressable component such as a button or a key. Here, when the screen lock operation module 110 includes a pressable component, the event of the screen lock operation module 110 being pressed may include the pressable component being pressed. Taking a key as an example, when the user presses (i.e., presses) the key, it is equivalent to triggering the event of the screen lock operation module 110 being pressed. At this time, a first trigger signal will be sent to the main control chip 210.

[0041] For example, the main control chip 210 may be equipped with a general purpose input / output (GPIO) interface, and the screen lock operation module 110 may be connected to the main control chip 210 through the GPIO interface.

[0042] For example, the main control chip 210 is also called a microcontroller unit (MCU) chip. Here, there is no specific limitation on the model and package form of the MCU chip.

[0043] In some embodiments, the indicator module 120 can be used to indicate the current usage status of the user's docking station. Therefore, the indicator module 120 may include an LED light to indicate the current usage status of the user's docking station, such as the source device 11 having entered a locked screen state. In some embodiments, the indicator module 120 is connected to the main control chip 210, which is used to light up the lock screen LED light when a first trigger signal is received.

[0044] It is understandable that the circuit board 200 is located inside the expansion dock housing 100. The circuit board 200 is used to carry the main control chip 210 and other circuits of the expansion dock. The main control chip 210 can be electrically connected to the screen lock operation module 110, the indicator module 120 and the external port module 130 respectively based on the circuit board 200.

[0045] For example, the external port module 130 may include a Type-C male connector, that is, the main control chip 210 can establish a connection with the source device 11 through the Type-C male connector.

[0046] In one embodiment, when the source device 11 is connected to the expansion dock through the external port module 130, the source device 11 is equivalent to a USB device. At this time, it is necessary to enumerate it. Enumeration means reading descriptor information from the source device 11. The main control chip 210 can determine which driver to load, what kind of device it is, and how to communicate based on the read descriptor information.

[0047] After the screen lock operation module 110 is pressed, the main control chip 210 can receive the first trigger signal sent by the screen lock operation module 110. At this time, it can control the indicator module 120 to work and control the source device 11 to enter the screen lock state through the external port module 130. In this way, users can intuitively understand the screen lock status of the source device 11 and improve the ease of use of the docking station.

[0048] In another embodiment of this application, an expansion dock is provided on the circuit board 200, which is also provided with an expansion module 220 connected to the main control chip 210, and an external port module 130 is provided on the expansion module 220.

[0049] refer to Figure 2 , Figure 2 The following is a schematic block diagram of the structure of an expansion dock provided in another embodiment of this application. It can be understood that the external port module 130 is disposed in the expansion module 220. The expansion module 220 is the module used by the expansion dock to set external ports to realize the port expansion function of the expansion dock. The expansion module 220 is connected to the main control chip 210. The main control chip 210 can coordinate the work of each port of the external port module 130 in the expansion module 220, process data conversion and transmission, and ensure that the expansion dock can operate stably and efficiently.

[0050] In another embodiment of this application, the expansion module 220 includes an expansion chip, which is electrically connected to the main control chip 210 and the external port module 130.

[0051] It is understandable that the expansion chip is used to control the operation of each port of the external port module 130 in the expansion module 220. The expansion chip is electrically connected to the main control chip 210 and the external port module 130 respectively, so that the main control chip 210 can coordinate the operation of each port of the external port module 130 in the expansion module 220 through the expansion chip.

[0052] In some embodiments, the main control chip 210 is used to control the source device 11 to enter a screen lock state according to the device identifier corresponding to the source device 11 when a first trigger signal is received; the device identifier corresponding to the source device 11 refers to the device identifier corresponding to the operating system of the source device 11; here, there is a mapping relationship between the device identifier and the operating system.

[0053] For example, the operating system of the source device 11 can be any of the following: Windows system, MAC system, Linux system or Android system, wherein each operating system has a corresponding device identifier; it should be noted that the device identifiers corresponding to the Linux system and the Android system can be the same, and this will be used as an example in the following explanation.

[0054] For example, if the operating system of the source device 11 is Windows, its corresponding device identifier can be 6695; if the operating system of the source device 11 is MAC, its corresponding device identifier can be 7695; and if the operating system of the source device 11 is Linux or Android, its corresponding device identifier can be 8695.

[0055] In some embodiments, the expansion chip can be a HUB expansion chip, which is connected to the main control chip 210. The HUB expansion chip is connected to the source device 11 through the external port module 130. The main control chip 210 is also used to generate a corresponding screen lock control command based on the device identifier and send the screen lock control command to the source device 11 through the HUB expansion chip, so that the source device 11 enters the screen lock state according to the screen lock control command.

[0056] Here, the type of HUB expansion chip can be determined according to the actual situation. This application embodiment does not make a specific limitation on this. For example, the HUB expansion chip can be a GL3510 chip or other types of expansion chips. The following description will take the GL3510 chip as an example.

[0057] For example, refer to Figure 3 , Figure 3 The diagram below shows the structure of an expansion dock provided in another embodiment of this application. When the HUB expansion chip is a GL3510 chip, it can expand to four USB ports. One USB port is connected to the MCU chip, and the other three USB ports are USB-A, USB-A and USB-C, which can be used to connect external devices such as TF / SD cards, mice or keyboards.

[0058] In this embodiment, the screen lock control command can be determined according to the operating system type of the source device 11. As can be seen from the above, each operating system has a corresponding device identifier. Therefore, after obtaining the device identifier corresponding to the source device 11, the main control chip 210 can determine the operating system of the source device 11 according to the device identifier, and then generate the corresponding screen lock control command according to the operating system of the source device 11.

[0059] For example, the screen lock control command refers to the Human Interface Device (HID) combination command, which is generated according to the screen lock key of the operating system of the source device 11. Assuming that the main control chip 210 determines that the operating system of the source device 11 is a Windows system based on the device identifier, the screen lock control command is generated according to the combination of the WINDOWS key and the letter L key (i.e., WIN+L); assuming that the main control chip 210 determines that the operating system of the source device 11 is a MAC system based on the device identifier, the screen lock control command is generated according to the combination of the WINDOWS key, the CTRL key, and the letter Q key (i.e., WIN+CTRL+Q); assuming that the main control chip 210 determines that the operating system of the source device 11 is a Linux system or an Android system based on the device identifier, the screen lock control command is generated according to the combination of the CTRL key, the ALT key, and the letter L key (i.e., CTRL+ALT+L).

[0060] Therefore, as can be seen from the above, the screen lock control command is used to lock the screen of the source device 11. Thus, when the source device 11 receives the screen lock control command sent by the main control chip 210, it will perform the screen lock operation and enter the screen lock state.

[0061] As can be seen, when users use the aforementioned docking station for screen mirroring, remote conferencing, and other activities, if they need to lock the screen, they can quickly lock the screen by pressing the button, effectively ensuring the data security of the source device 11 (e.g., a laptop, tablet, or mobile phone).

[0062] In some embodiments, the device identifier obtained by the main control chip 210 is sent by the source device 11 during the previous enumeration process; the process of the main control chip 210 obtaining the device identifier is illustrated below.

[0063] In some embodiments, the main control chip 210 is further configured to start the USB 2.0 protocol when it detects that the source device 11 is connected to the external port module 130, and enumerate the source device 11 according to the USB 2.0 protocol to obtain the descriptor information of the source device 11.

[0064] Here, the descriptor information may include not only the device identifier corresponding to the source device 11, but also the configuration descriptor, interface descriptor and endpoint descriptor of the source device 11. This application does not limit this.

[0065] For example, when the main control chip 210 detects that the source device 11 is connected to the external port module 130, it starts the USB 2.0 protocol. At this time, the source device 11 and the main control chip 210 establish a USB 2.0 data channel, and the main control chip 210 can enumerate the source device 11 according to the USB 2.0 data channel.

[0066] For example, refer to Figure 4 , Figure 4 The following is a schematic diagram of the process for controlling the screen lock of the source device 11 according to another embodiment of this application. After the source device 11 and the main control chip 210 establish a USB 2.0 data channel, the main control chip 210 will first send a descriptor information acquisition request to the source device 11. After receiving the request, the source device 11 acquires the descriptor information and sends the acquired descriptor information back to the main control chip 210. At this time, the main control chip 210 can obtain the descriptor information of the source device 11.

[0067] In some embodiments, the main control chip 210 is further configured to parse the descriptor information of the source device 11 to obtain the device identifier of the source device 11 upon receiving the first trigger signal.

[0068] In this embodiment, the main control chip 210 obtains the descriptor information of the source device 11 during the enumeration process of the source device 11, and the descriptor information includes the device identifier corresponding to the source device 11. In this way, when the first trigger signal is received subsequently, the device identifier corresponding to the source device 11 can be obtained by parsing the descriptor information.

[0069] For example, refer to Figure 4 After obtaining the device identifier corresponding to the source device 11, the main control chip 210 can generate a corresponding screen lock control command and send the screen lock control command to the source device 11 through the USB 2.0 data channel. When the source device 11 receives the screen lock control command sent by the main control chip 210, it will perform a screen lock operation and enter the screen lock state. The corresponding process has been described in the above embodiments, and will not be repeated here to avoid repetition.

[0070] In some embodiments, the screen lock operation module 110 is further configured to send a second trigger signal to the main control chip 210 when the screen lock operation module 110 is touched again; the main control chip 210 is further configured to, upon receiving the second trigger signal, obtain the device identifier of the source device 11 again, determine whether the device identifier obtained again has changed compared to the device identifier obtained last time, and if so, obtain a software upgrade package and perform a software upgrade according to the software upgrade package.

[0071] Understandably, the operating system of the source device 11 is likely to be updated based on actual usage needs. After such an update, the device identifier of the updated operating system may change. To ensure the reliability of the screen lock control, when the screen lock operation module 110 triggers another touch event, a second trigger signal is sent to the main control chip 210. When the main control chip 210 receives the second trigger signal, it will again obtain the device identifier of the source device 11, compare the newly obtained device identifier with the previously obtained device identifier, and then... The comparison result determines whether the device identifier has changed. If it has, a software upgrade package is obtained, and the software is upgraded according to the software upgrade package. In this way, the upgraded main control chip 210 can generate the corresponding lock screen control command according to the updated device identifier, and send the lock screen control command to the source device 11 through the HUB expansion chip, so that the source device 11 enters the lock screen state according to the lock screen control command. Otherwise, the corresponding lock screen control command is generated according to the unupdated device identifier, and the lock screen control command is sent to the source device 11 through the HUB expansion chip, so that the source device 11 enters the lock screen state according to the lock screen control command.

[0072] In another embodiment of this application, an expansion dock is provided, in which an indicator module 120 is arranged around a lock screen operation module 110.

[0073] It is understood that the screen lock operation module 110 may include pressable components such as buttons and keys, or pressure-sensitive buttons, virtual buttons, etc., while the indicator module 120 is used to indicate the user's current usage status of the docking station, for example, the source device 11 has entered the screen lock state. Therefore, the indicator module 120 can be configured accordingly with the screen lock operation module 110; Reference Figure 1 In this embodiment, the screen lock operation module 110 includes pressable components such as circular buttons and buttons, and the indicator module 120 is set around the circular buttons and buttons of the screen lock operation module 110. In this way, after the user operates the screen lock operation module 110, the indicator module 120 can intuitively understand whether the source device 11 has entered the screen lock state.

[0074] In another embodiment of the present application, the expansion dock includes an indicator module 120, which is used to light up when the external port module 130 is connected to the source device 11 and a communication connection is successfully established.

[0075] It is understood that the expansion dock provided in this application embodiment enables users to quickly control the source device 11 to enter the lock screen state. Furthermore, the external port module 130 of the expansion dock can provide multiple ports for connecting external devices. Therefore, the expansion dock can connect to the source device 11 and establish a communication connection.

[0076] Based on this, refer to Figure 5 , Figure 5 The following is a schematic diagram of the structure of an expansion dock provided in another embodiment of this application. In this embodiment, the indicator module 120 includes a first indicator light 121. In order to indicate the status of the user's external port module 130 being connected to the source device 11, the first indicator light 121 can be used for indication. That is, when the external port module 130 is connected to the source device 11 and a communication connection is successfully established, the first indicator light 121 can be lit by the main control chip 210 so that after the user connects to the source device 11, the indicator module 120 can intuitively understand whether the expansion dock has successfully connected to the source device 11 and established a communication connection.

[0077] In another embodiment of this application, the indicator module 120 further includes a second indicator light 122, which is used to be lit when the source device 11 enters the locked screen state.

[0078] It is understandable that the indicator module 120 is used to indicate the current usage status of the expansion dock. The usage status of the expansion dock includes whether the expansion dock has successfully connected to the source device 11 and established a communication connection, and whether the source device 11 has entered the screen lock state.

[0079] Based on this, refer to Figure 5 In this embodiment, the indicator module 120 includes a second indicator light 122. In order to indicate whether the user's source device 11 has entered the lock screen state, the second indicator light 122 can be used for indication. That is, when the source device 11 enters the lock screen state, the main control chip 210 can turn on the second indicator light 122 so that the user can intuitively understand whether the source device 11 has successfully entered the lock screen state after connecting the source device 11 through the indicator module 120.

[0080] In another embodiment of this application, the expansion dock 100 also includes a communication line 140 connected to the external port module 130.

[0081] It is understood that the external port module 130 is a module provided by the expansion dock to connect to the source device 11. The expansion dock can provide an interface for connecting the communication cable 140. Users can connect the interface of the expansion dock and the interface of the source device 11 through the communication cable 140 to achieve connection. Alternatively, the expansion dock can also directly provide the communication cable 140, as shown in the reference. Figure 6 , Figure 6 The diagram below shows the structure of an expansion dock provided in another embodiment of this application. A communication line 140 is provided on the interface of the expansion dock for connecting the source device 11, so that the user can connect to the interface of the source device 11 through the communication line 140.

[0082] In another embodiment of this application, the communication cable 140 is integrally formed with the housing 100 in the expansion dock.

[0083] In this embodiment, the communication cable 140 is integrated with the housing 100, which reduces the number of parts, simplifies the overall design, and reduces connection points, thereby reducing the risk of failure due to poor connection and improving the reliability of the expansion dock. In addition, in the usage scenarios of the expansion dock, the communication cable 140 and the interface are often frequently plugged and unplugged. Therefore, the integrated structure makes the connection between the communication cable 140 and the housing 100 more secure and less susceptible to external pulling or wear, thus enhancing the durability of the product.

[0084] In another embodiment of this application, the external port module 130 has an interface type including USB-A interface, USB-C interface, and Type-C interface.

[0085] In another embodiment of this application, the external port module 130 also includes a power interface for supplying power to the docking station.

[0086] In some embodiments, reference Figure 3 The docking station may also include a High Definition Multimedia Interface (HDMI) and a PD power interface. The HDMI interface can support a resolution of 4K@60Hz, and the PD power interface can support an input power of 100W. For example, the HDMI interface can be connected to a display device that meets the above resolution for screen mirroring, and the PD power interface can be connected to a power adapter that meets the above input power for charging.

[0087] For example, the expansion dock also includes a power chip and a video conversion chip; the power chip is connected to the PD power interface and the aforementioned Type-C male interface respectively, and is used to supply power to the various chips in the expansion dock to ensure that the chips work normally; the type of power chip can be determined according to the actual situation, and this embodiment does not make a specific limitation on it. For example, the power chip can be an SC8723 chip, or it can be other types of chips.

[0088] For example, the video conversion chip is connected to both the HDMI interface and the aforementioned Type-C male connector. The video conversion chip receives the video signal transmitted by the Type-C male connector, converts the received video signal into a Time Minimized Differential Signal (TMDS), and sends it to the HDMI interface for output via the display screen connected to the HDMI interface. The type of video conversion chip can be determined according to the actual situation, and this embodiment does not make a specific limitation. For example, the video conversion chip can be an AG9411 chip or other types of chips.

[0089] As can be seen, in this embodiment, if the above-mentioned docking station is applied to scenarios such as screen projection for office work and remote conferencing, when the user needs to leave the source device 11 briefly (e.g., a laptop or tablet), or when there is a need to prevent the screen information of the source device 11 from being leaked, the user can control the source device 11 to enter the lock screen state simply by touching the lock screen operation module 110. This enriches the functions of the docking station while effectively protecting the user's data and privacy, and meeting the user's needs for information security.

[0090] As can be seen from the above, if the docking station provided in this application is applied to scenarios such as screen projection for office work and remote conferencing, when the user needs to leave the source device 11 briefly (e.g., a laptop or tablet), or when there is a need to prevent the screen information of the source device 11 from being leaked, the user can control the source device 11 to quickly enter the lock screen state simply by touching the lock screen operation module 110. This enriches the functions of the docking station while effectively protecting the user's data and privacy, and meeting the user's needs for information security.

[0091] It should be noted that the technical solutions described in this application can be combined arbitrarily without conflict.
