Description

Technical Field

[0001] The present application relates to the field of hubs, and in particular to an extended combined USB hub and device. Background Art

[0002] With the continuous advancement of technology and the popularity of personal electronic devices, USB hubs have become an indispensable part of our daily lives. From offices to home entertainment systems to personal mobile offices, USB hubs provide connectivity and data transmission for a variety of devices.

[0003] Currently, the downstream HUB interface is generally a single transmission type. For example, the downstream HUB is generally used for data transmission or power supply. In addition, due to the application of Type C connection technology in recent years, the Type C interface has been given multiple functional applications. For example, the same Type C interface can realize USB data transmission, fast charging and video transmission functions. We call it a full-function Type C interface. However, this function is mainly used for the host USB Type CHost or the upstream of the USB HUB. Currently, the downstream does not generally have the full-function Type C feature. The downstream interface generally only has USB data connection communication. Consumers hope to directly drive the Type C interface display through the USB Type C downstream port, which requires connecting some other types of terminal devices for driving, which is inconvenient.

[0030] An embodiment of the present application provides an extended combined USB hub, comprising:

[0031] Input port, connected to the upstream device;

[0032] a control unit connected to the input port, the control unit including a separation module and a main control module connected to the separation module, the separation module being used to separate and transmit data transmitted by an uplink device, and the main control module being used to expand the port;

[0033] An output port, comprising an expansion interface, wherein the expansion interface is connected to the control unit;

[0034] An external unit, one end of which is connected to the expansion interface and the other end of which is connected to the downstream device. The external unit includes a selection module and a direct input module. Either the selection module or the direct input module is selectively connected to the expansion interface.

[0035] The above-mentioned extended combined USB hub system and device, by providing a control unit and an extended interface, allows downstream devices to directly drive the display through the input port; through the design of the extended interface connection that selects either a module or a direct input module, the user can choose the type of downstream device to be connected according to needs, thereby improving the compatibility and adaptability of the system.

[0036] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0037] according to Figures 1-6 In an embodiment of the present application, an extended combined USB hub 50 is provided, comprising: an input port 10, a control unit 20, an output unit and an external unit.

[0038] Among them, the input port 10 is connected to the upstream device; the control unit 20 is connected to the input port 10, the control unit 20 includes a separation module 21 and a main control module 22 connected to the separation module 21, the separation module 21 is used to separate the data transmitted by the upstream device and transmit it, and the main control module 22 is used to expand the port; the output port 30 includes an expansion interface 31, and the expansion interface 31 is connected to the control unit 20; one end of the external unit 40 is connected to the expansion interface 31, and the other end is connected to the downstream device, the external unit 40 includes a selection module 41 and a direct input module 42, and either the selection module 41 or the direct input module 42 is connected to the expansion interface 31.

[0039] Specifically, input port 10 is the entrance to the entire system, used to connect to upstream USB devices or hosts. The control unit 20 is the core unit of the hub 50 in this application, wherein the separation module 21 is responsible for separating and transmitting data transmitted by upstream devices. Through the separation module 21, the data of the upstream devices is effectively separated and the separated data signals are transmitted to different unit locations, thereby avoiding data congestion and conflicts and improving data transmission efficiency. The main control module 22 is a USB hub, commonly known as a USB hub 50 or USB extender, a device used to expand the number of USB interfaces. The expansion interface 31 is a port in the output port 30 and is used to connect to downstream devices. The design of the expansion interface 31 enables the hub 50 to support a wider variety of devices, providing a wider range of applications. Through the expansion interface 31, data can be efficiently transmitted from the control unit 20 to external devices. External units can choose different data transmission modes as needed, selecting either the direct input module 42 or the selection module 41 to connect to the expansion interface 31. This increases the scalability of the system and enhances its ease of use and flexibility.

[0040] Furthermore, in an embodiment of the present application, input port 10 is a UFP USB Type-C Plug Cable connector. When the UFP USB Type-C Plug Cable connector is connected to a host upstream device such as a mobile phone, tablet, or computer with Power Delivery (PD), a charging technology that allows up to 100W of power to be provided via a USB Type-C interface, the hub 50 of the present application immediately communicates with the host upstream device so that the host upstream device can automatically identify the hub 50 of the present application. Separation module 21 is a Power Delivery Controller & Type C Alternate Mode MUX unit. The Power Delivery Controller & Type C Alternate Mode MUX unit receives signals from the host upstream device, which may include multiple services such as power, data, and video. The MUX unit separates these signals into independent PD fast charging protocol services, data services, and video services through the internal separation module 21, and then distributes the PD fast charging protocol services, data services, and full-function video services to different units, simultaneously implementing all functions. The expansion interface 31 is a DFP1 USB Type C Data & D PALT Mode, which is a functional configuration in which the USB Type-C port plays a dual role, supporting both data transmission and display port alternate modes.

[0041] To summarize, the upstream device sends data to the control unit 20 via the input port 10. The separation module 21 within the control unit 20 separates and processes the data, ensuring that it flows correctly to the target device. The main control module 22 expands the number of ports as needed to increase connectivity. The processed data is transmitted to the external unit 40 via the expansion interface 31. Based on user needs, the selection module 41 of the external unit 40 determines the data transmission mode to use. The data is either transmitted directly to the downstream device via the direct transmission module 42 or optimized by the selection module 41 before being transmitted to the downstream device.

[0042] In a specific embodiment, the output port 30 has a first channel 30a formed by connecting the separation module 21, the main control module 22 and the expansion interface 31. The first channel 30a is used to transmit signals to the selection module 41 when the expansion interface 31 is connected to the selection module 41; the output port 30 also has a second channel 30b formed by connecting the separation module 21 and the expansion interface 31. The second channel 30b is used to transmit signals to the direct input module 42 when the expansion interface 31 is connected to the direct input module 42.

[0043] Specifically, the first channel 30a is the portion of the separation module 21 that connects the main control module 22 and the expansion interface 31, and is used to connect the expansion interface 31 to the selection module 41. When the separation module 21 assigns the separated independent data services to the USB hub unit, the separation module 21 combines with the main control module 22 to transmit the shared data service signals to the expansion interface 31. Once the data transmission path is established, the downstream port connected to the selection module 41 can perform bidirectional data transmission with the host upstream device. This allows data to be sent not only from the host upstream device to the peripheral device, but also from the peripheral device back to the host upstream device. This bidirectional data transmission capability greatly improves the flexibility and efficiency of the system.

[0044] Furthermore, second channel 30b, which connects the separation module 21 and the expansion interface 31, is used to connect the expansion interface 31 to the direct input module 42. The separation module 21 distributes the separated, independent video service signals directly to the expansion interface 31. When the expansion interface 31 is connected to the direct input module 42, the control module establishes a video transmission path from the host's upstream device to the downstream port connected to the direct input module 42. Once the video transmission path is established, the downstream device connected to the expansion interface 31 can receive the video signal from the host's upstream device and convert the host's upstream device's small screen into a large-scale display for display.

[0045] In a specific embodiment, the selection module 41 includes a first video module 411, a second video module 412 and a network connection module 413; the first video module 411 is connected to the extension interface 31 for transmitting a video connection; the second video module 412 is connected to the extension interface 31 for transmitting a video connection; the network connection module 413 is connected to the extension interface 31 for transmitting a data connection.

[0046] Specifically, the selection modules are multiple groups of connection devices with different functions. The first video module 411 is a connection device with a Type C to DP Converter function, the second video module 412 is a connection device with a Type C to HDMI Converter function, and the network connection module 413 is a connection device with a Type C to RJ45 Converter function. The main functions of the first video module 411 and the second video module 412 are to establish and maintain an uplink video connection with an external device, send and receive video signals through the extension interface 31, and ensure smooth transmission of video content. The network connection module 413 supports high-speed Internet access and device communication within the local area network, and provides stable network connection, data exchange and communication services through the extension interface 31.

[0047] In a specific embodiment, the first video module 411 includes a first connection port 4111, a signal separation module 4112 and a first transmission port 4113, the downstream device includes a first device, one end of the signal separation module 4112 is connected to the first connection port 4111, and the other end is connected to the first transmission port 4113, and the first transmission port 4113 is connected to the first device.

[0048] Specifically, when the first video module 411 is selected to be connected to the expansion interface 31, the Type C to DP Converter separates the Display Port protocol signal through the internal DP Alt-Mode Controller unit and establishes a first transmission port 4113, which is connected to the first device through the first transmission port 4113. The first device is a display device with a DP interface, which converts the small screen of the Host upstream device into a large-size display screen for display.

[0049] In a specific embodiment, the second video module 412 includes a second connection port 4121, a signal conversion module 4122 and a second transmission port 4123, and the downstream device also includes a second device. One end of the signal conversion module 4122 is connected to the second connection port 4121, and the other end is connected to the second transmission port 4123, and the second transmission port 4123 is connected to the second device.

[0050] Specifically, when the second video module 412 is selected to be connected to the expansion interface 31, the Type C to HDMI Converter can convert the DisplayPort protocol signal into an HDMI protocol signal through the internal Display Port Multi-Stream Hub Controller unit, and establish a downstream second transmission port 4123 DFP HDMI Port. The second transmission port 4123 is connected to the second device, which is a display device with an HDMI interface, and converts the small screen of the Host upstream device into a large-size display screen for display.

[0051] In a specific embodiment, the network connection module 413 includes a third connection port 4131, a data conversion module 4132 and a third transmission port 4133, and the downstream device also includes a third device. One end of the data conversion module 4132 is connected to the third connection port 4131, and the other end is connected to the third transmission port 4133, and the third transmission port 4133 is connected to the third device.

[0052] Specifically, when the network connection module 413 is selected to connect to the expansion interface 31, the USB to Gigabit Ethernet Controller unit in the network connection module 413 converts USB data into Ethernet data and generates a downstream third transmission port 4133DFP RJ45 Port. The third transmission port 4133 is used to connect to a third device, which is an Ethernet Device and provides network connection, data exchange and communication services.

[0053] In a specific embodiment, the direct transmission module 42 is a network cable, the downstream device includes a fourth device, one end of the network cable is connected to the expansion interface 31, and the other end is connected to the fourth device.

[0054] Specifically, the network cable is a DP Alt Mode-enabled network cable. When the direct input module 42 is connected to the expansion interface 31, the DP Alt Mode-enabled network cable is directly connected to the fourth device. By connecting the network cable to the expansion interface 31, the small screen of the host upstream device is converted into a large display screen.

[0055] In a specific embodiment, the output port 30 includes a charging interface 32 , and the charging interface 32 is connected to the separation module 21 .

[0056] Specifically, in this embodiment of the present application, the charging interface 32 is a USB Type-C PD100W. When the charging interface 32 is connected to a downstream device, the separation module 21 distributes the separated independent PD fast charging protocol service to the charging interface 32. One end of the charging interface 32 is connected to a power adapter with Power Delivery function. At the same time, the other end of the charging interface 32 establishes communication with the host upstream device with Power Delivery function connected to the input port 10 and provides fast charging service to the host upstream device.

[0057] In a specific embodiment, the output port 30 further includes a plurality of transmission interfaces 33 , and the plurality of transmission interfaces 33 are respectively connected to the main control modules 22 .

[0058] Specifically, in an embodiment of the present application, the number of transmission interfaces is three. The separation module 21 distributes the separated independent data services to the USB HUB unit. The host upstream device connected to the input port 10 can communicate with the hub 50 of the present application through the USB HUB unit and establish a data connection and exchange data. Simultaneously, the USB HUB unit generates three USB downstream ports: DFP2 USB Port, DFP3 USB Port, and DFP4 USB Port. These three downstream ports can connect to downstream devices and perform bidirectional data transmission with the host upstream device.

[0059] The present application provides an extended combined USB hub 50 device, including an extended combined USB hub 50 system 100 as described above, including: a hub 50 body and an external device 60 connected to the body, the external device 60 including a first connection group 61 and a second connection group 62, and either the first connection group 61 or the second connection group 62 is selectively connected to the body.

[0060] Specifically, the first connection group 61 is a variety of adapter connectors with different functions. In the embodiment of the present application, the first connection group 61 includes three types of adapter connectors: a Type C to HDMI adapter connector, a Type C to DP adapter connector, and a Type C to RJ45 adapter connector. By selecting different adapter connectors for connection with the hub 50, the Type C to HDMI adapter connector, the Type C to DP adapter connector, and the Type C to RJ45 adapter connector can be used in combination with the hub 50. The second connection group 62 is a DP Alt Mode cable, which directly communicates with the DP Alt Mode cable through the downstream device to achieve video transmission function.

[0061] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
