[0043] In some embodiments, after receiving the first trigger signal sent by the lock screen operation module 101, the master control chip 102 controls the LED lamp to light up, and controls the source device 20 to enter the lock screen state according to the device identifier corresponding to the source device 20. In this way, the user can intuitively understand the lock screen state of the source device 20, and the use convenience of the docking station is improved.

[0044] It can be understood that the docking station is a device for expanding the functions of an externally connected electronic device, that is, the externally connected electronic device is connected through a specific interface, thereby providing additional ports and functions for the externally connected electronic device. For example, the docking station can provide multiple ports for the electronic device to connect more external devices, such as a mouse, a keyboard, a display, a printer, etc. It can also achieve multi-screen display or high-definition video output through a video data port. It can also charge the externally connected electronic device and provide more stable network connection, etc.

[0045] According to some embodiments of the present application, referring to FIG. 2, the lock screen control device 10 includes a lock screen operation module 101, a master control chip 102, and an expansion module 103. The lock screen operation module 101 and the expansion module 103 are respectively connected to the master control chip 102, or the expansion module 103 and the master control chip 102 are integrally arranged on the same chip.

[0046] In some embodiments, as shown in FIG. 2, the expansion module 103 includes an expansion chip, which is respectively connected to the master control chip 102 and the source device 20. The master control chip 102 is further configured to generate a corresponding lock screen control instruction according to the device identifier, and send the lock screen control instruction to the source device 20 through the expansion chip, so that the source device 20 enters the lock screen state according to the lock screen control instruction.

[0047] In some embodiments, the expansion chip includes a HUB expansion chip. The HUB expansion chip is used to expand multiple USB interfaces. The type of the HUB expansion chip can be determined according to actual conditions, and is not specifically limited. For example, the HUB expansion chip can be a GL3510 chip, or other types of expansion chips. Hereinafter, the GL3510 chip is taken as an example for description.

[0048] According to some embodiments of the present application, please refer to FIG. 3, in the case that the HUB expansion chip is a GL3510 chip, it can expand four USB interfaces, one of which is connected with the MCU chip, and the other three are USB-A, USB-A and USB-C respectively, which can be used to access TF / SD card, mouse or keyboard and other external devices.

[0049] In some embodiments, the lock screen control instruction can be determined according to the operating system type of the source device 20. Since each operating system has a corresponding device identifier, after obtaining the device identifier corresponding to the source device 20, the master control chip 102 can determine the operating system of the source device 20 according to the device identifier, and then generate the corresponding lock screen control instruction according to the operating system of the source device 20.

[0050] In some embodiments, the lock screen control instruction refers to a Human Interface Device (HID) combination instruction, which is generated by the master control chip 102 according to the operating system of the source device 20 and the shortcut keys of the operating system. Assuming that the master control chip 102 determines that the operating system of the source device 20 is the Windows system according to the device identifier, the lock screen control instruction is generated according to the combination of the WINDOWS key and the letter L key (i.e. WIN+L); assuming that the master control chip 102 determines that the operating system of the source device 20 is the MAC system according to the device identifier, the lock screen control instruction is generated according to the combination of the WINDOWS key, the CRTL key and the letter Q key (i.e. WIN+CRTL+Q); assuming that the master control chip 102 determines that the operating system of the source device 20 is the linux system, the Hongmeng system or the Android system according to the device identifier, the lock screen control instruction is generated according to the combination of the CRTL key, the ALT key and the letter L key (i.e. CTRL+ALT+L).

[0051] In some embodiments, the lock screen control instruction is used to lock the source device 20, so when the source device 20 receives the lock screen control instruction sent by the master control chip 102, it will perform the lock screen operation and enter the lock screen state.

[0052] In the process of the user using the expansion dock containing the above-mentioned lock screen control device 10 to perform screen projection office, remote conference and other behaviors, if there is a lock screen requirement, it can be realized by pressing the key to quickly lock the screen, effectively ensuring the data security of the source device 20 (such as a notebook computer, a tablet computer, or a mobile phone).

[0053] In some embodiments, the device identifier obtained by the master control chip 102 is sent by the source device 20 in the previous enumeration process. The process of the master control chip 102 obtaining the device identifier is exemplarily described as follows.

[0054] According to some embodiments of the present application, referring to FIG. 3 and FIG. 4, the lock screen control device 10 further comprises an external port module 104, which is arranged in the expansion module 103, i.e., a module for arranging external ports to realize the port expansion function of the docking station. The expansion module 103 is electrically connected with the master control chip 102. The master control chip 102 can coordinate the work of each port of the external port module 104 in the expansion module 103, process the conversion and transmission of data, and ensure that the docking station can operate stably and efficiently.

[0055] In some embodiments, the expansion chip establishes a connection with the source device 20 through the external port module 104. At this time, the master control chip 102 is further used to control the source device 20 to enter the lock screen state through the external port module 104 in the case that the lock screen operation module 101 is touched and pressed.

[0056] In some embodiments, the lock screen operation module 101 can include a pressable component such as a (round) key, a button, etc., and can also be a pressure-sensitive key, a virtual button, etc. Here, in the case that the lock screen operation module 101 includes a pressable component, the event that the lock screen operation module 101 is touched and pressed can include that the pressable component is pressed. Taking the key as an example for illustration, when the user presses (i.e., presses) the key, it is equivalent to triggering the event that the lock screen operation module 101 is touched and pressed. At this time, a first trigger signal is sent to the master control chip 102.

[0057] It can be understood that the expansion chip is used to control the work of each port of the external port module 104 in the expansion module 103. The expansion chip is electrically connected with the master control chip 102 and the external port module 104, respectively, so that the master control chip 102 can coordinate the work of each port of the external port module 104 in the expansion module 103 through the expansion chip.

[0058] In some embodiments, since the external port module 104 is used to establish a communication connection with the source device 20, the external port module 104 can include USB-C, USB-A, Type-C, etc. interfaces through which a communication connection with the source device 20 can be established. In addition, the external port module 104 can also include HDMI, DisplayPort, VGA, DVI, etc. types of video interfaces, an Ethernet port for providing wired network connection, an audio port, a power supply interface (the power supply interface is configured to supply power to the lock screen control device 10), a Thunderbolt port, and eSATA, FireWire, etc., a special port for the connection of a specific device.

[0059] For example, the external port module 104 is a USB interface, and the HUB expansion chip establishes a connection with the source device 20 through the USB interface. Here, the USB interface is also referred to as an uplink USB interface, which is used to access the source device 20.

[0060] For example, the USB interface can be a Type-C male interface, that is, the HUB expansion chip can establish a connection with the source device 20 through the Type-C male interface, as shown in FIG. 3.

[0061] In some embodiments, when the source device 20 accesses the docking station through the external port module 104, the source device 20 is equivalent to a USB device, and at this time, the source device 20 needs to be enumerated. The enumeration is to read descriptor information from the source device 20, and the host chip 102 can determine what driver to load, what kind of device it is, and how to communicate according to the read descriptor information.

[0062] For example, the external port module 104 is a USB interface, and the HUB expansion chip establishes a connection with the source device 20 through the USB interface. Here, the USB interface is also referred to as an uplink USB interface, which is used to access the source device 20.

[0063] In some embodiments, the host chip 102 is further configured to start a USB2.0 protocol when detecting that the source device 20 accesses the external port module 104, and to enumerate the source device 20 according to the USB2.0 protocol to obtain descriptor information of the source device 20.

[0064] For example, the external port module 104 is a USB interface, and the HUB expansion chip establishes a connection with the source device 20 through the USB interface. Here, the USB interface is also referred to as an uplink USB interface, which is used to access the source device 20.

[0065] In some embodiments, the host chip 102 starts a USB2.0 protocol when detecting that the source device 20 accesses the external port module 104, and at this time, the source device 20 and the host chip 102 establish a USB2.0 data channel, and the host chip 102 can enumerate the source device 20 according to the USB2.0 data channel.

[0066] For example, the external port module 104 is a USB interface, and the HUB expansion chip establishes a connection with the source device 20 through the USB interface. Here, the USB interface is also referred to as an uplink USB interface, which is used to access the source device 20.

[0067] In some embodiments, the descriptor information may include, in addition to the device identifier corresponding to the source device 20, information such as the configuration descriptor, interface descriptor, and endpoint descriptor of the source device 20, which is not limited herein.

[0068] In some embodiments of the present application, during the process of enumerating the source device 20, the main control chip 102 will obtain the descriptor information of the source device 20, and the descriptor information includes the device identifier corresponding to the source device 20. Thus, when the first trigger signal is received subsequently, by parsing the descriptor information, the device identifier corresponding to the source device 20 can be obtained.

[0069] According to some embodiments of the present application, referring to FIG. 5, after the source device 20 and the main control chip 102 establish a USB2.0 data channel, the main control chip 102 will first send a descriptor information acquisition request to the source device 20. After receiving the request, the source device 20 acquires the descriptor information and returns the acquired descriptor information to the main control chip 102. At this time, the main control chip 102 can obtain the descriptor information of the source device 20.

[0070] In some embodiments, the main control chip 102 is further configured to parse the descriptor information of the source device 20 to obtain the device identifier corresponding to the source device 20. Specifically, the main control chip 102 is configured to parse the descriptor information of the source device 20 to obtain the device identifier of the source device 20 when the first trigger signal is received.

[0071] In some embodiments, referring to FIGS. 3 and 5, after the main control chip 102 obtains the device identifier corresponding to the source device 20, it can generate a corresponding lock screen control instruction and send the lock screen control instruction to the source device 20 through the USB2.0 data channel. When the source device 20 receives the lock screen control instruction sent by the main control chip 102, it will perform a lock screen operation and enter the lock screen state; the corresponding process has been described in the above embodiments, and to avoid repeated description, it will not be elaborated here.

[0072] In some embodiments, the lock screen operation module 101 is further configured to send a second trigger signal to the main control chip 102 when the event that the lock screen operation module 101 is pressed again is triggered; the main control chip 102 is further configured to, when receiving the second trigger signal, obtain the device identifier of the source device 20 again, determine whether the device identifier obtained again has changed compared with the device identifier obtained last time, and if it is determined that it has changed, obtain a software upgrade package and perform software upgrade according to the software upgrade package.

[0073] In some embodiments, the lock screen operation module 101 is further configured to send a second trigger signal to the master chip 102 in the case of occurrence of a human-computer interaction event again; and the master chip 102 is further configured to acquire the device identifier of the source device 20 again in the case of receiving the second trigger signal, determine whether the acquired device identifier is changed compared with the last acquired device identifier, acquire the software upgrade package in the case of yes, and perform software upgrade according to the software upgrade package.

[0074] It can be understood that the operating system of the source device 20 is likely to be updated according to actual use requirements, and the device identifier of the updated operating system is likely to be changed. In order to ensure the reliability of the lock screen control, the lock screen operation module 101 sends a second trigger signal to the master chip 102 in the case of occurrence of a human-computer interaction event again. When the master chip 102 receives the second trigger signal, the device identifier of the source device 20 is acquired again, and the acquired device identifier is compared with the last acquired device identifier, and the comparison result is used to determine whether the device identifier is changed. If yes, the software upgrade package is acquired, and software upgrade is performed according to the software upgrade package to obtain the upgraded master chip 102. In this way, the upgraded master chip 102 can generate the corresponding lock screen control instruction according to the updated device identifier, and send the lock screen control instruction to the source device 20 through the expansion chip, so that the source device 20 enters the lock screen state again according to the lock screen control instruction. Otherwise, the corresponding lock screen control instruction is generated according to the un-updated device identifier, and the lock screen control instruction is sent to the source device 20 through the expansion chip, so that the source device 20 enters the lock screen state according to the lock screen control instruction.

[0075] In some embodiments, referring to FIG. 3, the lock screen control device 10 can further include a high-definition multimedia interface (HDMI) and a PD interface, wherein the HDMI interface can support a resolution of 4K@60HZ, and the PD interface can support an input power of 100W. Illustratively, the HDMI interface can be connected to a display device conforming to the above resolution for screen projection, and the PD interface can be connected to a power adapter conforming to the above input power for charging.

[0076] In some embodiments, the lock screen control device 10 further comprises a power supply chip and a video conversion chip; here, the power supply chip is connected with the Power Delivery (PD) interface and the Type-C male interface mentioned above, and is used to supply power to each chip in the lock screen control device 10 to ensure the normal work of the chip; here, the type of the power supply chip can be determined according to actual conditions, and is not specifically limited, for example, referring to FIG. 3, the power supply chip can be an SC8723 chip, or can be a chip of other models.

[0077] In some embodiments, the video conversion chip is connected with the HDMI interface and the Type-C male interface mentioned above; the video conversion chip is used to receive the video signal transmitted by the Type-C male interface, convert the received video signal into a Time Minimized Differential Signal (TMDS), and send it to the HDMI interface for output via the display screen connected with the HDMI interface. Here, the type of the video conversion chip can be determined according to actual conditions, and is not specifically limited, for example, referring to FIG. 3, the video conversion chip can be an AG9411 chip, or can be a chip of other models.

[0078] It can be seen that if the docking station containing the lock screen control device 10 is applied to the scenarios of screen projection office and remote conference, when the user needs to leave the source device 20 (for example, a notebook computer or a tablet computer) temporarily, or there is a need to prevent the screen information of the source device 20 from being leaked, the user can only control the source device 20 to enter the lock screen state by operating the lock screen operation module 101, thereby enriching the functions of the docking station, effectively protecting the data and privacy of the user, and meeting the user's demand for information security.

[0079] According to some embodiments of the present application, referring to FIGS. 3 and 6, the lock screen control device 10 further comprises an indication module 105 connected with the master control chip 102, which can be used to indicate the current use state of the docking station to the user, and the indication module 105 can comprise an LED lamp, which indicates the current use state of the docking station to the user, for example, the source device 20 has entered the lock screen state, etc.; in some embodiments, the master control chip 102 is used to light the lock screen LED lamp when receiving the first trigger signal.
