[0039] To illustrate the technical solutions provided by this application, the following will be described in detail with reference to specific drawings and embodiments.

[0040] A docking station, also known as a port replicator, is an external device designed specifically for laptop computers. By replicating or even expanding the ports of a notebook computer, it enables the laptop to be conveniently connected to multiple accessories or external devices (such as a power adapter, network cable, mouse, external keyboard, printer, and external monitor) in a one-stop manner. However, existing docking stations have the problem of incomplete functions and cannot meet the diverse functional requirements of users for docking stations.

[0041] Based on the above problems, this application proposes a docking station circuit and device, including: a first data transmission interface for receiving first data to be transmitted sent by a first device to be expanded; a wireless signal receiving module for receiving second data to be transmitted sent by a second device to be expanded; a data switching module coupled to the first data transmission interface and the wireless signal receiving module for selectively outputting the first data to be transmitted and the second data to be transmitted; a data transfer module coupled to the data switching module; and a second data transmission interface, one end of which is coupled to the data transfer module and the other end of which is coupled to an expansion device. By using the docking station circuit and device provided by this application, not only does the docking station have the ability to connect multiple interfaces, but it also incorporates the convenience of wireless signal transmission, achieving a dual improvement in functionality and being able to adapt to the usage requirements in different scenarios.

[0042] To illustrate the technical solutions of this application, the following will be described through specific embodiments.

[0043] Figure 1 The schematic diagram of the docking station circuit structure provided by a preferred embodiment of this application is shown. For the sake of convenience of description, only the parts related to this embodiment are shown and are described in detail as follows.

[0044] The docking station circuit provided by the embodiment of this application includes:

[0045] The first data transmission interface 100 is used to connect to the first device to be expanded when the first device to be expanded needs to be expanded, so as to receive the first data to be transmitted sent by the first device to be expanded;

[0046] The wireless signal receiving module 200 is used to receive the second data to be transmitted sent by the second device to be expanded;

[0047] The data switching module 300 is coupled to the first data transmission interface 100 and the wireless signal receiving module 200. The data switching module 300 is used to selectively output the first data to be transmitted and the second data to be transmitted;

[0048] The data transfer module 400 is coupled to the data switching module 300;

[0049] One end of the second data transmission interface 500 is coupled to the data transfer module 400, and the other end is coupled to the expansion device.

[0050] It should be noted that the first data transmission interface 100 is a wired interface of the docking station, which is used to connect the first device to be expanded. When the first device to be expanded needs to expand its functions, it can send the first data to be transmitted to the docking station through this interface. Among them, the first device to be expanded can be an electronic device such as a laptop, a tablet computer or a smart phone, and the expansion functions required by the first device to be expanded include: external devices such as an external display, a keyboard, and a mouse. Exemplarily, the first data transmission interface 100 can be a Type-C interface.

[0051] The wireless signal receiving module 200 is responsible for receiving the second data to be transmitted from the second device to be expanded, and can support multiple wireless communication technologies, such as Bluetooth, Wi-Fi Direct, etc., to realize wireless connection and data transmission with the second device to be expanded. Among them, the second device to be expanded can be an electronic device such as a smart phone or a tablet computer that supports wireless transmission.

[0052] The data switching module 300 selectively outputs the first data to be transmitted received by the first data transmission interface and the second data to be transmitted received by the wireless signal receiving module 200. The selection process can be carried out according to a preset rule or according to the user's selection. Exemplarily, the data switching module 300 can be an ASW3410 signal switching switch chip.

[0053] The data transfer module 400 receives the data from the data switching module 300, and performs necessary format conversion or signal processing to ensure that the data can be smoothly transmitted between the devices to be expanded (including the first device to be expanded and the second device to be expanded) and the expansion device.

[0054] The second data transmission interface 500 is an interface between the expansion dock and the expansion device. The expansion device can be various external devices, such as a display, a projector, a hard disk drive, etc. The expansion device transmits data with the first device to be expanded or the second device to be expanded through this interface.

[0055] It should be noted that the expansion dock circuit provided in the present application serves as an intermediate bridge between the device to be expanded and the expansion device. By setting up multiple second data transmission interfaces 500 and corresponding data transfer modules 400, the device to be expanded can be connected and transmit data with different expansion devices. In addition, a first data transmission interface, a wireless signal receiving module 200 and a data switching module 300 are set, so that the device to be expanded and the expansion device can be connected and transmit data by wire or wirelessly.

[0056] Specifically, when in use, the device to be expanded can be connected to the expansion dock circuit through the first data transmission interface to achieve a wired connection between the device to be expanded and the expansion dock circuit; or, the device to be expanded and the expansion dock circuit can be connected wirelessly through the wireless signal receiving module 200. In this way, the expansion dock circuit can achieve data transmission without a wired connection with the device to be expanded.

[0057] It should be noted that wired connections transmit data directly through physical cables, and the stability and reliability of data transmission are higher. In addition, wired connections have large bandwidth and fast data transmission speeds, which are suitable for application scenarios where large amounts of data are transmitted or high-speed data transmission is performed. In addition, for wired transmission methods, since the data transmission path is short and direct, it usually has lower latency, which is suitable for application scenarios that require real-time response, such as games, video editing, etc.

[0058] As for wireless transmission, since it is free from the constraints of cables, the connection between the expanded device and the expansion dock circuit is more flexible and convenient. Users can move the equipment freely without being restricted by cable length. Moreover, within an appropriate range, wireless connection also supports remote data transmission, which is very useful for application scenarios that require data transmission across rooms or floors.

[0059] In summary, the expansion dock circuit provided by the present application serves as a central hub, including a variety of data transmission interfaces, which can connect multiple devices to achieve data sharing and interaction, and supports both wired and wireless data transmission methods. Wired connection and wireless connection each have their own advantages, and users can choose the appropriate connection method according to specific application scenarios and needs. For example, when high-speed, stable, and secure data transmission is required, a wired connection can be selected; while in the scenario of pursuing flexibility, convenience, and space cleanliness, a wireless connection is more appropriate.

[0060] In a possible implementation, refer to Figure 2 , the wireless signal receiving module 200 includes:

[0061] A wireless signal receiving unit 201, which is used to receive the second data to be transmitted sent by the second device to be expanded;

[0062] A wireless signal conversion unit 202, one end of the wireless signal conversion unit is coupled to the wireless signal receiving unit, and the other end is coupled to the data switching module 300.

[0063] It should be noted that the wireless signal receiving module 200 includes a wireless signal receiving unit 201 and a wireless signal conversion unit 202. The two units work together to receive wireless signals from the second device to be expanded and convert them into a suitable data format.

[0064] Specifically, the wireless signal receiving unit 201 is responsible for receiving the second data to be transmitted sent by the second device to be expanded. It usually includes components such as an antenna, a radio frequency (RF) front-end circuit, and a demodulator, which are used to capture, amplify, demodulate, and preliminarily process wireless signals. When the second device to be expanded sends data wirelessly (such as Bluetooth, Wi-Fi, etc.), these data are propagated in the air in the form of electromagnetic waves. The antenna of the wireless signal receiving unit 201 captures these electromagnetic waves and performs processing such as amplification and filtering through the RF front-end circuit. Then, the demodulator restores the data signal modulated on the carrier to a baseband signal and transmits it to the wireless signal conversion unit 202.

[0065] The wireless signal conversion unit 202 receives the data preliminarily processed by the wireless signal receiving unit 201 and converts it into a data format that the data switching module 300 can understand and process. Specifically, the wireless signal conversion unit 202 performs necessary processing on the data according to a predetermined conversion rule or protocol stack standard. Exemplarily, the processing process includes: unpacking of data packets, decoding of data, error detection and correction, etc. Finally, the converted data is output in a form suitable for processing by the data switching module 300 for subsequent data transmission or processing.

[0066] Exemplarily, the wireless signal conversion unit 202 includes a network card receiving module chip operating at an electromagnetic wave frequency of 2.4 GHz (ultra-high frequency), which can convert the received electromagnetic wave frequency into a USB DATA signal.

[0067] It should also be noted that the wireless signal receiving unit 201 can be wirelessly connected to and transmit data with the second device to be expanded through WiFi or Bluetooth. This application does not limit the wireless connection method, and other methods that can achieve wireless data transmission can also be used in this application.

[0068] In a possible implementation, the data transfer module 400 includes: a first video conversion unit 401. The second data transmission interface 500 includes: a first video data transmission interface 501, a second video data transmission interface 502, and a third video data transmission interface 503. One end of the first video conversion unit 401 is coupled to the first data transmission interface 100, and the other end is coupled to the first video data transmission interface 501, the second video data transmission interface 502, and the third video data transmission interface 503. The first video conversion unit 401 is configured to perform format conversion on the first data to be transmitted.

[0069] Exemplarily, the first video data transmission interface 501 may be a DP (DisplayPort), the second video data transmission interface 502 may be an HDMI (High Definition Multimedia Interface), and the third video data transmission interface 503 may be a VGA interface (Video Graphics Array). The first video conversion unit 401 may be a VMM3332 video conversion chip, which can convert the DP signal of the PC side into DP / HDMI / VGA video signals for output. Moreover, the VMM3332 supports the 4K high-definition video transmission standard and can meet the needs of users with high-definition video output requirements. In addition, the VMM3332 supports multi-screen different displays and can transmit video signals to multiple monitors. For the office scenario, it can achieve multitasking and effectively improve work efficiency.

[0070] During use, when the expansion device is connected through one of the HDMI, DP, or VGA interfaces, its EDID information will be transferred to the first device to be expanded. When the first device to be expanded receives the EDID signal, it will transmit the audio and video signals of the corresponding resolution according to the requirements of the expansion device.

[0071] It should be noted that the present application does not limit the type of the first video conversion unit 401, and any chip or circuit structure capable of realizing video signal conversion can be used in the present application.

[0072] In a possible implementation, the data transfer module 400 includes: a second video conversion unit 402. The second data transmission interface 500 includes: a fourth video data transmission interface 504. One end of the second video conversion unit 402 is coupled to the data switching module 300, and the other end is coupled to the fourth video data transmission interface 504. The second video conversion unit 402 is configured to perform format conversion on the second data to be transmitted.

[0073] It should be noted that in the previous embodiment, the first video conversion unit 401 is used to perform format conversion on the first data to be transmitted from the first data transmission interface 100, while in this embodiment, the second video conversion unit 402 is used to perform format conversion on the second data to be transmitted from the wireless signal receiving module 200. Exemplarily, the second video conversion unit 402 can be an SM768 video media processor, which can convert USB digital signals into HDMI signals. Moreover, the SM768 supports up to 4K ultra-high definition (UHD) resolution. For creative workers and entertainment enthusiasts who require high-definition video transmission, the SM768 provides a more stable and efficient video transmission solution, capable of meeting the requirements of picture quality and smoothness.

[0074] In a possible implementation, the docking station circuit further includes: a bridging module 600, and one end of the bridging module 600 is coupled to the first data transmission interface 100.

[0075] There are problems with insufficient types or quantities of existing docking station interfaces, resulting in limited connectivity and the inability to connect all required devices simultaneously. For example, some docking stations may lack an HDMI interface, making it impossible to directly connect to a high-definition monitor or projector, or the number of USB interfaces is limited and cannot meet the needs of simultaneous charging and data transmission for multiple devices. Or, some docking stations may not include an RJ45 network interface, or the performance of the network interface is limited (such as only supporting 100Mbps network), thus restricting the user's performance when dealing with network-intensive tasks.

[0076] In the embodiment of the present application, a bridging module 600 is added. It is coupled to the first data transmission interface 100 and can expand the signal transmitted by the first data transmission interface 100 into multiple signal outputs. After subsequent processing by the data switching module 400, it can be converted into various formats of data or signals and then transmitted via different second data transmission interfaces 500. The setting of the bridging module 600 makes the docking station circuit scalable, and more data transmission interfaces or functional modules can be added according to needs to meet the requirements of different users and scenarios.

[0077] Exemplarily, the bridging module 600 can include a VL817-Q7S chip, which can expand one USB signal into four USB signals. The bridging module 600 can also include a GL850 chip, which can expand one USB2.0 signal into multiple USB2.0 signals.

[0078] In a possible implementation, the docking station circuit further includes: a protocol communication unit 700, and one end of the protocol communication unit 700 is coupled to the first data transmission interface 100, and the other end is coupled to the data switching module 300 and the bridging module 600.

[0079] It should be noted that the protocol communication unit 700 can be used for protocol communication between the first device to be expanded and the data switching module 300, the bridging module 600, and the power supply module 800. Exemplarily, the protocol communication unit 700 can be a VL102 chip.

[0080] In a possible implementation, the second data transmission interface 500 further includes: a first serial data interface 505, and the first serial data interface 505 is coupled to the protocol communication unit 700.

[0081] Exemplarily, the first serial data interface 505 can be a USB Type-C interface, and based on the fast charging protocol of the USB Type-C connection standard, the first serial data interface 505 can support video and data output and PD charging functions for type-c interface mobile phones and computers. Their working power can be automatically switched between DownType-C or Up Type-C. Among them, DownType-C is separately equipped to ensure the normal supply current for charging and the maximum BC1.2 charging current. Among them, BC1.2 is a protocol that supports 5V 1.5A fast charging for phones / ipads.

[0082] In a possible implementation, the second data transmission interface 500 further includes: a second serial data interface 506, and the second serial data interface 506 is coupled to the bridging module 600.

[0083] It should be noted that the second serial data interface 506 can be different USB interfaces such as USB 2.0, USB 3.0, USB 3.1, USB 4.0, etc.

[0084] In a possible implementation, the data transfer module 400 includes: a memory card control unit 403, and the second data transmission interface 500 includes: a memory card interface 508; one end of the memory card control unit 403 is coupled to the bridging module 600, and the other end is coupled to the memory card interface 508.

[0085] Exemplarily, the memory card control unit 403 can be an AU84612 card reader chip, which can read the content of an SD card or a TF card and transfer it.

[0086] In a possible implementation, the data transfer module 400 includes: a network signal processing unit 404, and the second data transmission interface 500 includes: a network cable interface 509; one end of the network signal processing unit 404 is coupled to the bridging module 600, and the other end is coupled to the network cable interface 509.

[0087] Exemplarily, the network signal processing unit 404 may be an RTL8153B network card chip, and the network port signal can be converted into a data signal by the RTL8153B network card chip for the PC to connect to the network.

[0088] In a possible implementation manner, the data transfer module 400 includes: an audio control unit 405, and the second data transmission interface 500 includes: an audio interface 507; one end of the audio control unit 405 is coupled to the bridging module 600, and the other end is coupled to the audio interface 507.

[0089] Exemplarily, the audio control unit 405 may be an HS-100 audio chip.

[0090] In a possible implementation manner, the docking station circuit further includes: a power module 800, one end of the power module 800 is coupled to the first data transmission interface 100, and the other end is coupled to the wireless signal receiving module 200, the data switching module 300, the data transfer module 400, and the second data transmission interface 500 to supply power to the wireless signal receiving module 200, the data switching module 300, the data transfer module 400, and the second data transmission interface 500.

[0091] Exemplarily, the power module 800 includes an SC8903 buck-boost chip, which can convert the 20V voltage of the charger into 5V to supply power to each module, unit, and interface; it also includes a PMOS field effect transistor for power switching. Specifically, the PMOS field effect transistor mainly switches between PD IN20V (power adapter) and PC side (computer) power taking to flexibly switch between charger and computer power supply.

[0092] The embodiment of the present application further provides a docking station device, including the above docking station circuit.

[0093] It should be noted that the docking station device provided by the present application serves as an intermediate bridge between the device to be expanded and the expansion device. By setting a variety of second data transmission interfaces 500 and corresponding data transfer modules 400, the device to be expanded can be connected to different expansion devices for data transmission. Moreover, by setting the first data transmission interface 100, the wireless signal receiving module 200, and the data switching module 300, the device to be expanded and the expansion device can be connected and data transmitted in a wired or wireless manner.

[0094] Specifically, when in use, the device to be expanded can be connected to the docking station device through the first data transmission interface 100 to achieve a wired connection between the device to be expanded and the docking station device; or, the device to be expanded and the docking station device can be connected in a wireless connection manner through the wireless signal receiving module 200. In this way, the docking station device can achieve data transmission without being wired to the device to be expanded.

[0095] It should be noted that wired connection directly transmits data through physical cables, with relatively high stability and reliability of data transmission. Moreover, wired connection has a large bandwidth and fast data transmission speed, making it suitable for application scenarios that require transmitting a large amount of data or high-speed data transmission. Additionally, for the wired transmission method, due to the short and direct data transmission path, it usually has lower latency and is suitable for application scenarios that require real-time response, such as games, video editing, etc.

[0096] For the wireless transmission method, since it gets rid of the bondage of cables, the connection between the device to be expanded and the docking station device becomes more flexible and convenient. Users can freely move the device to be expanded and the expansion device without being restricted by the cable length. Moreover, within an appropriate range, wireless connection also supports remote data transmission, which is very useful for application scenarios that require data transmission across rooms or floors.

[0097] In summary, the docking station device provided in this application, as a central hub, includes a variety of data transmission interfaces, can connect multiple devices to achieve data sharing and interaction, and supports both wired and wireless data transmission methods. Wired connection and wireless connection each have their own advantages, and users can choose the appropriate connection method according to specific application scenarios and requirements. For example, when high-speed, stable, and secure data transmission is required, wired connection can be selected; while in scenarios where flexibility, convenience, and spatial neatness are pursued, wireless connection is more suitable.
