By copying or even expanding the ports of notebook computers, notebook computers can be conveniently connected with multiple accessories or external devices (such as power adapter, network cable, mouse, external keyboard, printer and external display). However, the existing docking station has the problem of incomplete function, which cannot meet the diversified needs of users for docking station function.

[0037] Based on the above problems, the present application provides a docking station circuit and device, comprising: a first data transmission interface for receiving first to-be-transmitted data sent by a first to-be-expanded device; a wireless signal receiving module for receiving second to-be-transmitted data sent by a second to-be-expanded device; a data switching module coupled to the first data transmission interface and the wireless signal receiving module, for selectively outputting the first to-be-transmitted data and the second to-be-transmitted data; a data conversion module coupled to the data switching module; a second data transmission interface, one end of which is coupled to the data conversion module, and the other end of which is coupled to an expansion device. The docking station circuit and device provided by the present application not only have the ability of multi-interface connection, but also integrate the convenience of wireless signal transmission, realizing double improvement in function, and being able to adapt to the use needs in different scenarios.

[0038] To illustrate the technical solutions provided in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0039] FIG. 1 shows a docking station circuit structure schematic diagram provided by the preferred embodiment of the present application. For the convenience of description, only the parts related to the present embodiment are shown, which are described in detail as follows.

[0040] The docking station circuit provided by the embodiment of the present application comprises:

[0041] The first data transmission interface 100 is used to connect with the first device to be expanded when the first device to be expanded needs to be expanded, so as to receive the first to-be-transmitted data sent by the first device to be expanded.

[0042] The wireless signal receiving module 200 is used to receive the second to-be-transmitted data sent by the second device to be expanded.

[0043] The data switching module 300 is coupled with the first data transmission interface 100 and the wireless signal receiving module 200, and is used to output the first to-be-transmitted data and the second to-be-transmitted data alternately.

[0044] The data switching module 300 is coupled with the first data transmission interface 100 and the wireless signal receiving module 200, and is used to output the first to-be-transmitted data and the second to-be-transmitted data alternately.

[0045] The second data transmission interface 500 is coupled with the data switching module 300 at one end and with the expansion device at the other end.

[0046] 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 be expanded, the first to-be-transmitted data can be sent to the docking station through the interface. The first device to be expanded can be a notebook computer, a tablet computer or a smart phone, and the expansion function required by the first device to be expanded includes 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.

[0047] The wireless signal receiving module 200 is responsible for receiving the second to-be-transmitted data from the second device to be expanded, and can support multiple wireless communication technologies such as Bluetooth and Wi-Fi Direct, so as to realize wireless connection and data transmission with the second device to be expanded. The second device to be expanded can be a smart phone, a tablet computer or other electronic devices supporting wireless transmission.

[0048] The data switching module 300 outputs the first to-be-transmitted data received by the first data transmission interface and the second to-be-transmitted data received by the wireless signal receiving module 200 alternately. The selection process can be performed according to a preset rule or according to the selection of a user. Exemplarily, the data switching module 300 can be an ASW3410 signal switching switch chip.

[0049] The data switching module 300 outputs the first to-be-transmitted data received by the first data transmission interface and the second to-be-transmitted data received by the wireless signal receiving module 200 alternately. The selection process can be performed according to a preset rule or according to the selection of a user. Exemplarily, the data switching module 300 can be an ASW3410 signal switching switch chip.

[0050] The second data transmission interface 500 is an interface between the docking station and the expansion device, which can be various external devices such as a display, a projector, a hard drive, etc. The expansion device can perform data transmission with the first device to be expanded or the second device to be expanded through the interface.

[0051] It should be noted that the docking station circuit provided in the present application serves as an intermediate bridge between the device to be expanded and the expansion device. By providing a plurality of second data transmission interfaces 500 and corresponding data conversion modules 400, the device to be expanded can be connected to and perform data transmission with different expansion devices. In addition, the first data transmission interface, the wireless signal receiving module 200, and the data switching module 300 are provided to enable the device to be expanded and the expansion device to be connected and perform data transmission through wired or wireless means.

[0052] Specifically, in use, the device to be expanded can be connected to the docking station circuit through the first data transmission interface to achieve wired connection between the device to be expanded and the docking station circuit. Alternatively, the device to be expanded can be connected to the docking station circuit in a wireless manner through the wireless signal receiving module 200, so that the docking station circuit can perform data transmission without wired connection to the device to be expanded.

[0053] It should be noted that wired connection directly transmits data through physical cables, and has high stability and reliability of data transmission. In addition, wired connection has a large bandwidth and fast data transmission speed, which is suitable for application scenarios that require transmission of a large amount of data or high-speed data transmission. In addition, for wired transmission, the data transmission path is short and direct, usually with lower latency, which is suitable for application scenarios that require real-time response, such as gaming and video editing.

[0054] As for the wireless transmission method, the connection between the device to be expanded and the docking station circuit is more flexible and convenient because it is free from the constraints of cables, and users can freely move the devices without being limited by the length of the cable. In addition, within a certain range, wireless connection also supports remote data transmission, which is very useful for application scenarios that require data transmission across rooms or floors.

[0055] In summary, the docking station circuit provided in the present application serves as a central hub that contains a plurality 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 the specific application scenario and requirements. For example, in the case of high-speed, stable, and secure data transmission, wired connection is preferred. In the case of flexibility, convenience, and space neatness, wireless connection is more suitable.

[0056] In a possible implementation, referring to FIG. 2, the wireless signal receiving module 200 includes:

[0057] a wireless signal receiving unit 201, configured to receive second to-be-transmitted data sent by a second to-be-extended device;

[0058] a wireless signal converting unit 202, one end of which is coupled to the wireless signal receiving unit, and the other end of which is coupled to the data switching module 300.

[0059] It should be noted that the wireless signal receiving module 200 includes the wireless signal receiving unit 201 and the wireless signal converting unit 202, and the two units work cooperatively to receive wireless signals from the second to-be-extended device and convert the wireless signals into a suitable data format.

[0060] Specifically, the wireless signal receiving unit 201 is responsible for receiving the second to-be-transmitted data sent by the second to-be-extended device, and usually includes an antenna, a radio frequency (RF) front-end circuit, a demodulator and the like, for capturing, amplifying, demodulating and preliminarily processing wireless signals. When the second to-be-extended device sends data by a wireless manner (such as Bluetooth, Wi-Fi and the like), the data propagates in the air in the form of electromagnetic waves, the antenna of the wireless signal receiving unit 201 captures the electromagnetic waves, and the RF front-end circuit performs amplification, filtering and the like on the electromagnetic waves, and then the demodulator restores the data signal modulated on the carrier wave into a baseband signal and transmits the baseband signal to the wireless signal converting unit 202.

[0061] The wireless signal converting unit 202 receives the data preliminarily processed by the wireless signal receiving unit 201, and converts the data into a data format that can be understood and processed by the data switching module 300. Specifically, the wireless signal converting unit 202 performs necessary processing on the data according to a predetermined conversion rule or a protocol stack standard. Exemplarily, the processing process includes: unpacking of data packets, decoding of data, error detection and correction and the like. Finally, the converted data is output in a form suitable for processing by the data switching module 300, for subsequent data transmission or processing.

[0062] Exemplarily, the wireless signal converting unit 202 includes an electromagnetic wave 2.4 GHz (ultra-high frequency) working frequency network card receiving module chip, which can convert the received electromagnetic wave frequency into a USB DATA signal.

[0063] It should be further noted that the wireless signal receiving unit 201 can be wirelessly connected to and transmit data with the second to-be-extended device by a WiFi or Bluetooth manner, and the application does not limit the manner of wireless connection, and other manners that can realize wireless data transmission can also be used in the application.

[0064] In a possible implementation, the data switching module 400 comprises a first video conversion unit 401, the second data transmission interface 500 comprises 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, and the first video conversion unit 401 is configured to perform format conversion on the first to-be-transmitted data.

[0065] For example, the first video data transmission interface 501 can be a DP (DisplayPort, display interface), the second video data transmission interface 502 can be an HDMI (High Definition Multimedia Interface, high-definition multimedia interface), the third video data transmission interface 503 can be a VGA interface (Video Graphics Array), and the first video conversion unit 401 can be a VMM3332 video conversion chip, which can convert a DP signal of a PC end into a DP / HDMI / VGA video signal for output. In addition, the VMM3332 supports a 4K high-definition video transmission standard and can meet the needs of users who require high-definition video output. Furthermore, the VMM3332 supports multi-screen heterogeneous display and can transmit a video signal to multiple displays. For an office scenario, the VMM3332 can realize multi-task processing and effectively improve work efficiency.

[0066] In use, when the expansion device is connected through one of the HDMI, DP, or VGA interfaces, the EDID information of the expansion device will be forwarded to the first to-be-expanded device, and the first to-be-expanded device will transmit an audio and video signal of a corresponding resolution according to the requirements of the expansion device after receiving the EDID signal.

[0067] It should be noted that the type of the first video conversion unit 401 is not limited in the present application, and any chip or circuit structure capable of realizing video signal conversion can be used in the present application.

[0068] In a possible implementation, the data switching module 400 comprises a second video conversion unit 402, the second data transmission interface 500 comprises 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, and the second video conversion unit 402 is configured to perform format conversion on the second to-be-transmitted data.

[0069] It should be noted that in the previous embodiment, the first video conversion unit 401 is used for format conversion of the first to-be-transmitted data from the first data transmission interface 100, while the second video conversion unit 402 in the present embodiment is used for format conversion of the second to-be-transmitted data from the wireless signal receiving module 200. Exemplarily, the second video conversion unit 402 can be an SM768 video media processor, which can convert a USB digital signal into an HDMI signal. Moreover, the SM768 supports a super high definition (UHD) resolution of up to 4K, and provides a more stable and efficient video transmission solution for creative workers and entertainment enthusiasts who need high-definition video transmission, and can meet the requirements of image quality and smoothness.

[0070] In a possible implementation, the docking station circuit further includes a bridge module 600, one end of the bridge module 600 being coupled to the first data transmission interface 100.

[0071] The existing docking station interface is insufficient in types or quantity, and has the problem of limited connectivity, and cannot simultaneously connect all the required devices. For example, some docking stations can lack an HDMI interface, resulting in the inability to directly connect a high-definition display or a projector, or the number of USB interfaces is limited, which cannot meet the needs of simultaneous charging and data transmission of multiple devices, or some docking stations can not contain an RJ45 network interface, or the performance of the network interface is limited (such as only supporting a hundred megabit network), thereby limiting the performance of the user when processing network-intensive tasks.

[0072] In the embodiments of the present application, the bridge module 600 is added, which 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, the signal can be converted into various formats of data or signals, and then transmitted through different second data transmission interfaces 500. The setting of the bridge module 600 makes the docking station circuit extensible, and more data transmission interfaces or functional modules can be added as needed to meet the needs of different users and scenes.

[0073] Exemplarily, the bridge module 600 can include a VL817-Q7S chip, which can expand one USB signal into four USB signals. The bridge module 600 can also include a GL850 chip, which can expand one USB2.0 signal into multiple USB2.0 signals.

[0074] In a possible implementation, the docking station circuit further includes a protocol communication unit 700, one end of the protocol communication unit 700 being coupled to the first data transmission interface 100, and the other end being coupled to the data switching module 300 and the bridge module 600.

[0075] It should be noted that the protocol communication unit 700 can be used for the 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. For example, the protocol communication unit 700 can be a VL102 chip.

[0076] 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 with the protocol communication unit 700.

[0077] For example, 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 the type-c interface mobile phone and computer video and data output and PD charging function, and the working power source can be automatically switched by Down Type-C or Up Type-C, wherein the Down Type-C is separately configured to ensure the normal power supply current of charging and the maximum BC1.2 charging current capacity, and the BC1.2 is a protocol supporting Phone / ipad fast charging 5V 1.5A.

[0078] 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 with the bridging module 600.

[0079] It should be noted that the second serial data interface 506 can be a USB 2.0, USB 3.0, USB 3.1, USB 4.0, or the like.

[0080] In a possible implementation, the data switching 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 with the bridging module 600, and the other end is coupled with the memory card interface 508.

[0081] For example, the memory card control unit 403 can be an AU84612 card reader chip, which can read and transmit the content of an SD card or a TF card.

[0082] In a possible implementation, the data switching module 400 includes a network signal processing unit 404, and the second data transmission interface 500 includes a network interface 509; one end of the network signal processing unit 404 is coupled with the bridging module 600, and the other end is coupled with the network interface 509.

[0083] Exemplarily, the network signal processing unit 404 can be an RTL8153B network card chip, and the network signal can be converted into a data signal by the RTL8153B network card chip to connect the network of the PC computer.

[0084] In a possible implementation, the data switching module 300 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 bridge module 600, and the other end is coupled to the audio interface 507.

[0085] Exemplarily, the audio control unit 405 can be an HS-100 audio chip.

[0086] In a possible implementation, 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 switching 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 switching module 400 and the second data transmission interface 500.

[0087] Exemplarily, the power module 800 includes an SC8903 step-up / down chip, which can convert the 20V voltage of the charger into 5V to supply power to each module, unit and interface; and a PMOS field effect transistor is used for power switching, specifically, the PMOS field effect transistor is mainly used for switching PD IN20V (power adapter) and PC (computer) power supply, and flexibly switching the charger and the computer power supply.

[0088] The embodiment of the present application also provides a docking station device, which includes the above docking station circuit.

[0089] It should be noted that the docking station device provided by the present application serves as an intermediate bridge between the to-be-extended device and the extended device, and through the arrangement of the plurality of second data transmission interfaces 500 and the corresponding data switching modules 400, the to-be-extended device can be connected with and transmit data with different extended devices, and the arrangement of the first data transmission interface 100, the wireless signal receiving module 200 and the data switching module 300 enables the to-be-extended device and the extended device to be connected and transmit data through wired or wireless mode.

[0090] Specifically, in use, the to-be-extended device can be connected with the docking station device through the first data transmission interface 100 to realize wired connection between the to-be-extended device and the docking station device; or the to-be-extended device can be connected with the docking station device in a wireless connection mode through the wireless signal receiving module 200, so that the docking station device can realize data transmission without wired connection with the to-be-extended device.

[0091] It should be noted that the wired connection directly transmits data through a physical cable, and the stability and reliability of data transmission are higher. In addition, the wired connection has a large bandwidth and fast data transmission speed, which is suitable for application scenarios that require transmission of a large amount of data or high-speed data transmission. In addition, for the wired transmission mode, since the data transmission path is short and direct, it usually has lower delay, which is suitable for application scenarios that require real-time response, such as games, video editing, etc.

[0092] For the wireless transmission mode, since it is free from the constraints of cables, the connection between the to-be-extended device and the docking station device is more flexible and convenient, and the user can freely move the to-be-extended device and the docking station device without being limited by the length of the cable. In addition, within a suitable range, wireless connection also supports remote data transmission, which is very useful for application scenarios that require data transmission across rooms or floors.

[0093] In summary, the docking station device provided by the present application serves as a central hub, contains multiple data transmission interfaces, can connect multiple devices, realizes data sharing and interaction, and supports wired and wireless data transmission modes. Wired connection and wireless connection each have their own advantages, and users can choose the appropriate connection mode according to the specific application scenario and needs. For example, when high-speed, stable, and secure data transmission is required, wired connection can be selected. In the scene of pursuing flexibility, convenience, and space neatness, wireless connection is more suitable.
