[0001] The present application relates to the technical field of electronic products, and particularly to a data cable. Background Art

[0002] Current electronic device products such as ultra-thin laptops, mobile phones or tablet computers are powerful and are equipped with various interfaces for connecting external devices, such as DMI (High Definition Multimedia Interface), VGA (Video Graphics Array), DP (Display Port), LAN (Local Area Network), USB A, etc. However, these interfaces are too thick, which does not conform to the existing design concepts of portability, thinness, and beauty.

[0003] If only a single, more powerful Type-c small interface is used as the data, audio-video, and power supply interface, but because USB devices related to reading, writing, and communication such as USB flash drives, USB mice, and keyboards in the market, as well as audio-video devices (external devices), still retain the original interface types, the interfaces between devices cannot be compatible and effective connections cannot be established. Summary of the Utility Model

[0004] Based on this, the present utility model provides a data cable capable of establishing an effective connection between devices with different types of interfaces.

[0005] The present utility model provides a data cable with a docking station, and the docking station includes a power management circuit. The power management circuit includes a power controller, a protocol controller, and a power supply controller, and the power controller is connected to the protocol controller and the power supply controller;

[0006] Wherein, the protocol controller is configured to obtain protocol data of an external device;

[0007] The power controller is configured to control the power supply controller according to the protocol data;

[0008] The power supply controller is configured to control the power management circuit to supply power to the external device, or receive power supply from the external device.

[0009] In one embodiment, the docking station is provided with a plurality of expansion interfaces, and at least one of the expansion interfaces is configured to connect a power adapter to supply power to the power supply controller through the power adapter.

[0010] In one embodiment, the docking station is provided with a plurality of expansion interfaces, and the expansion interfaces include a plurality of data transmission ports of different types.

[0011] In one embodiment, it includes multiple sub-lines for power or data transmission between the multiple sub-lines and external devices.

[0012] In one embodiment, the multiple sub-lines include multiple power supply lines, and the power supply lines only support powering the external devices.

[0013] In one embodiment, the multiple sub-lines include multi-functional lines;

[0014] wherein, the multi-functional lines are configured for data transmission and power transmission with the external devices.

[0015] In one embodiment, M power supply line interfaces are connected to N power supply lines, and M is a positive integer less than or equal to N.

[0016] In one embodiment, the docking station is located between the multi-functional lines and the multiple power supply lines.

[0017] In one embodiment, the data line includes multiple sub-lines, and the multiple sub-lines include sub-data lines supporting data transmission; the expansion interfaces supporting data transmission and the sub-data lines are both connected to the data processing circuit; the data processing circuit is configured to support processing the data transmitted by the expansion interfaces and the sub-data lines.

[0018] In one embodiment, the data processing circuit includes a network management circuit and / or an audio-video processing circuit; the network management circuit and / or the audio-video processing circuit are connected to a data line controller, and the data line controller is also connected to the power management circuit;

Thus, external devices with different interface types can establish an effective connection with the electronic device through the interfaces of the docking station on the data cable. Integrating the function of the docking station into the data cable eliminates the need to configure a dedicated docking station for the electronic device separately. Only one data cable is required to meet the multi-functional requirements, which is convenient to carry and also avoids damage to the interfaces of the electronic device caused by repeated plugging and unplugging. The docking station included in the data cable has a power management circuit, and the power management circuit includes a power controller, a protocol controller and a power supply controller. Through the power controller, the protocol controller and the power supply controller are cooperatively controlled, so that the protocol controller and the power supply controller can be compatible with each other and avoid instruction conflicts between different controllers. Therefore, through the protocol controller, protocol handshaking with external devices can be performed to be compatible with multiple protocols, so that the power supply controller can adaptively adjust the power supply parameters according to the protocol data, thereby meeting the power supply requirements of different types of connector devices.

[0026] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0028] It can be understood that for the "connection" in the following embodiments, if there is a transfer of electrical signals or data between the connected circuits, modules, units, etc., it should be understood as "electrical connection", "communication connection", etc.

[0029] It can be understood that "at least one" means one or more, and "a plurality" means two or more. "At least part of an element" means part or all of the element.

[0030] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprises / include" or "has" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0031] Current electronic devices such as ultra-thin laptops, mobile phones or tablets adopt small interfaces as external interfaces due to the design concept of pursuing portability, thinness and beauty. However, the previous interfaces such as HDMI (High Definition Multimedia Interface), VGA (Video Graphics Array), DP (Display Port), LAN (Local Area Network), USB A, etc. are too thick and do not conform to the existing design concepts of portability, thinness and beauty. In newly produced ultra-thin laptops, mobile phones or tablets and other devices, there are no external HDMI, VGA, DP (Display Port), LAN, USB A and other interfaces, but only the more powerful Type-c interface is used as the data, audio / video, and power supply interface. In this case, the existing data cables do not have the function of expanding interfaces, while the existing docking stations can expand the Type-c interfaces of laptops, mobile phones or tablets. In this case, the existing data cables do not have the function of expanding interfaces. Once the only Type-c interface on the laptop / mobile phone / tablet is occupied by one end of the data cable, it is difficult to expand other functions. In this way, it is necessary to pull out the data cable connector and replace it with a device with the corresponding function, which is cumbersome to operate and the repeated plugging and unplugging is likely to damage the Type-c interface.

[0032] In an exemplary embodiment, as Figure 1 shown, the data line of an embodiment has a docking station. The docking station includes a power management circuit, and the power management circuit includes a power controller, a protocol controller, and a power supply controller. The power controller is connected to the protocol controller and the power supply controller. Among them, the protocol controller is configured to obtain protocol data of an external device; the power controller is configured to control the power supply controller according to the protocol data; the power supply controller is configured to control the power management circuit to supply power to the external device or receive power supply from the external device.

[0033] The power controller is the main control unit for power management in the data line.

[0034] The docking station includes an expansion interface for connecting to a terminal and can be connected to an external device through the expansion interface to provide additional ports and functions to enhance the flexibility of the device.

[0035] The protocol controller is a control unit in the data line that can perform data interaction according to multiple protocols. The protocol adapted to the external device can be determined through the protocol controller; then communicate with the external device according to the protocol adapted to the external device to achieve protocol handshake with the external device, so as to be compatible with multiple protocols such as fast charging and flash charging. Since the protocol controller is provided in the data line, the data line can identify and interact with the external device without using an external device as a relay device, so that the interface of the electronic device can be increased through the docking station while the electronic device can still retain a small interface.

[0036] The power supply controller is a control unit capable of power supply regulation. Optionally, the power supply controller can charge the external device according to the protocol data or receive power supply from the external device to achieve power transmission according to the charging protocol adapted to the external device.

[0037] The protocol data is data that interacts with the controller of the data line. Since the protocols adapted to external devices may vary, adaptation and conversion can be performed through the protocol controller. Optionally, the protocol data can be data sent to the power controller and then sent to the protocol controller by the power controller, or data sent to the protocol controller without passing through the power controller.

[0038] The power controller, the protocol controller, and the power supply controller are integrated into a power control circuit; the power control circuit is controlled by the data line controller, and charging control data is sent to the power controller through the data line controller to achieve power transmission control between the data line and the external device.

[0039] In this embodiment, the data cable is provided with a docking station, so that electronic devices such as ultra-thin laptops, mobile phones or tablets can add different types of interfaces through the docking station on the data cable while retaining a single small interface type (such as a Type-c interface). Thus, external devices with different interface types can establish an effective connection with the electronic device through the interfaces of the docking station on the data cable. Integrating the functions of the docking station into the data cable eliminates the need to configure a dedicated docking station for the electronic device separately. Only one data cable is required to meet the multi-functional requirements, which is convenient to carry and also avoids damage to the interfaces of the electronic device caused by repeated plugging and unplugging. The docking station included in the data cable comprises a power management circuit, and the power management circuit includes a power controller, a protocol controller and a power supply controller. Through the power controller, the protocol controller and the power supply controller are controlled collaboratively, so that the protocol controller and the power supply controller can be compatible with each other and avoid instruction conflicts between different controllers. Therefore, through the protocol controller, protocol handshaking with external devices can be performed to be compatible with multiple protocols, so that the power supply controller can adaptively adjust the power supply parameters according to the protocol data to meet the power supply requirements of different types of connector devices.

[0040] In one embodiment, the docking station is provided with a plurality of expansion interfaces, and at least one expansion interface is configured to connect a power adapter to supply power to the power supply controller through the power adapter.

[0041] The expansion interface includes an interface adapted to at least one charging protocol, so that the electric energy output by the power adapter can be transmitted to the charging cable through the expansion interface. Optionally, the expansion interface is controlled by the HUB controller of the docking station and is used to charge external devices.

[0042] Optionally, the power supply controller can be directly connected to the expansion interface or indirectly connected to the expansion interface via other controllers.

[0043] In this embodiment, since the number of expansion interfaces is multiple, more external devices can be connected through the expansion interfaces, liberating the ports on the sub-cable of the data cable. Moreover, when the power adapter is connected through the expansion interface, the electric energy does not need to be transmitted through the sub-cable to the power supply controller. Therefore, not only does it not occupy the ports on the sub-cable of the data cable, but also more external devices can be charged through the unoccupied ports on the sub-cable. Thus, the ports on the sub-cable of the data cable are liberated, making the charging connector ports more sufficient, and the sub-cable of the data cable can be relatively fewer, which is easy to organize and carry.

[0044] In one embodiment, the docking station is provided with a plurality of expansion interfaces, and the plurality of expansion interfaces include a plurality of data transmission ports of different types.

[0045] The data transmission port is a port in the expansion interface and can perform data transmission. Since the number of expansion interfaces is relatively large, external devices with different interface types can perform data transmission based on the expansion interface through the data transmission port. Optionally, the expansion interface and the data transmission port can be in one-to-one correspondence, and one type of data transmission port that supports the same protocol can also correspond to multiple expansion interfaces.

[0046] Optionally, each type of data transmission port can be in one-to-one correspondence with a data transmission protocol, or each type of data transmission port can correspond to multiple protocols, or multiple types of data transmission ports can correspond to the same protocol. Optionally, the types of data transmission ports include but are not limited to Universal Serial Bus (USB); Universal Serial Bus (Type-C) that supports plugging in either direction, High Definition Multimedia Interface (HDMI), Digital Visual Interface (DVI), DisplayPort (DP), Video Graphics Array (VGA), and at least one interface among Registered Jack 45 (RJ45) for Ethernet. That is, the data transmission ports include but are not limited to at least one interface among USB interface, type-c interface, HDMI interface, DVI interface, DP interface, VGA interface, and RJ45.

[0047] Optionally, the data transmission port can support connecting a power adapter to supply power to the power supply controller through the expansion interface. For example, the type-c interface supports both connecting a power adapter and data transmission of different protocols.

[0048] Thus, since the number of expansion interfaces is multiple, the electronic device can connect more external devices through the expansion interface, liberating the ports of the data cable on the sub-line. Moreover, when there are multiple data transmission ports in the expansion interface, the ports of the data cable on the sub-line are liberated, enabling the unoccupied ports of the sub-line to add multiple functions and realizing data interaction between the electronic device and multiple external devices.

[0049] In one embodiment, the data cable includes multiple sub-lines for performing power or data transmission with external devices through the multiple sub-lines.

[0050] The sub-line is a branch line carrying at least one port. Each sub-line can only support the power transmission function, only support the data transmission function, and can also support both the power and data transmission functions simultaneously.

[0051] Optionally, multiple sub-lines can be disposed on the docking station or at other positions of the data cable.

[0052] Optionally, the protocol controller is respectively connected to multiple sub-lines so that the multiple sub-lines can perform data transmission to an external device; and / or, the power supply controller is respectively connected to multiple sub-lines so that the multiple sub-lines can perform power transmission with the external device.

[0053] Among them, the cases of data transmission include but are not limited to the case of transmitting data from the sub-line to the external device, the case of transmitting data from the external device to the sub-line, and the case of data interaction between the sub-line and the external device. The cases of power transmission include but are not limited to the case of supplying power from the sub-line to the external device and the case of supplying power from the external device to the sub-line.

[0054] In this embodiment, the data cable includes multiple sub-lines, and each sub-line can have at least one of the functions of power transmission and data transmission. When the multiple sub-lines have the power transmission function, power transmission can be performed with multiple external devices through multiple sub-lines of one data cable; when the multiple sub-lines have the data transmission function, data transmission can be performed on multiple external devices through multiple sub-lines of one data cable; when the multiple sub-lines have both the power transmission function and the data transmission function, power supply and data transmission can be performed on multiple external devices through multiple sub-lines of one data cable.

[0055] In an alternative embodiment, the multiple sub-lines include a power supply line that only supports power supply to an external device.

[0056] Optionally, multiple sub-lines can be disposed on the docking station or at other positions of the data cable.

[0057] The power supply line is a data cable that only has the function of supplying power to an external device. Optionally, there can be multiple power supply lines to charge multiple external devices. Optionally, the multiple sub-lines can simultaneously include a power supply line and a sub-data cable that at least supports data transmission, so as to perform data transmission through the sub-data cable and power transmission through the power supply line. Optionally, the multiple sub-lines can include a multi-functional line and a power supply line, so as to perform data transmission through the multi-functional line and power transmission through the power supply line. Optionally, the sub-data cable with the data transmission function is a multi-functional line that supports both data transmission and power transmission.

[0058] In this embodiment, the power supply line separates the data transmission function from the function of powering external devices, reducing electrical interference, avoiding potential damage to sensitive electronic components caused by current fluctuations, and also reducing the safety risks during data transmission, such as avoiding data errors or damage. Moreover, the power supply line can support faster charging protocols and higher currents without worrying about data transmission limitations, thus achieving faster charging speeds and better power management. In addition, the internal design of the power supply line is simple, making maintenance and upgrade more convenient. If a problem occurs with the function of one of the power supply lines, only the corresponding line needs to be replaced or repaired without affecting other sub-lines.

[0059] In an alternative embodiment, multiple said sub-lines include a multi-functional line; wherein, the multi-functional line is configured to perform data transmission and power transmission with the external device.

[0060] The multi-functional line is a data line capable of performing data transmission and power transmission to an external device, so that the multi-functional data line has multiple functions. Among them, the data transmission cases include, but are not limited to, the case of transmitting data from the multi-functional line to the external device, the case of transmitting data from the external device to the multi-functional line, and the case of data interaction between the multi-functional line and the external device.

[0061] The power transmission cases include, but are not limited to, the case of being powered by the external device, or the case of the multi-functional line powering the external device. Optionally, in the case of power transmission between the multi-functional line and the external device, power supply is carried out in accordance with the charging power supported by the external device and the multi-functional line, which can make the charging and discharging efficiency of the external device relatively high.

[0062] Thus, the multi-functional line has a data transmission function and a power transmission function, which can make the application scenarios of the data line more extensive.

[0063] In an alternative embodiment, N power supply lines are connected to M types of power supply line interfaces, where M is a positive integer less than or equal to N.

[0064] The power supply line interface is an interface for the power supply line to output electrical energy. Since N power supply lines are connected to M types of power supply line interfaces, different external devices can perform data transmission based on the power supply line through the power supply line interface. Optionally, the power supply line interface includes, but is not limited to, the Universal Serial Bus (USB); the Universal Serial Bus (Type-C) that supports plugging in either way. That is, the power supply line interface includes, but is not limited to, the USB interface and the type-c interface.

[0065] Optionally, the power supply line interface can support connecting a power adapter to supply power to the power supply controller through the power supply line interface. For example, the power supply line interface is a type-c interface, which not only supports connecting a power adapter but also supports data transmission of different protocols.

[0066] In this embodiment, when N power supply lines are connected to M types of power supply line interfaces, the power supply lines are dedicated to power supply, enabling devices supporting different charging protocols to charge through their respective adapted power supply lines.

[0067] In an optional embodiment, the docking station is located between the multi-functional line and multiple power supply lines.

[0068] Optionally, the expansion interface between the multi-functional line and multiple power supply lines can support connecting a power adapter and can also include multiple data transmission ports supporting different protocols.

[0069] Optionally, there are multiple expansion interfaces between the multi-functional line and multiple power supply lines. At least one expansion interface supports connecting a power adapter, and the expansion interfaces also include multiple data transmission ports supporting different protocols.

[0070] In this embodiment, with the docking station located between the multi-functional line and multiple power supply lines, the three functionally related parts of the docking station, the multi-functional line, and multiple power supply lines can be independent of each other.

[0071] In an exemplary embodiment, as Figure 2 shown, the multiple sub-lines include a multi-functional line. The external devices include a first external device connected to the multi-functional line and a second external device connected to the power supply line. The multi-functional line supports data transmission and power supply to the first external device;

[0072] Among them, the multi-functional line is configured to be powered by the first external device based on the charging power supported by the first external device, or to supply power to the first external device; the power supply line is configured to supply power to the second external device based on the remaining power of the multi-functional line. The remaining power is the power difference between the charging power supported by the data line and the charging power supported by the first external device.

[0073] The multi-functional line is a data line capable of data transmission or power transmission to the first external device, so that the multi-functional data line has different functions. When the multi-functional line charges the first external device, power is supplied through the multi-functional line according to the charging power supported by the first external device, which can make the charging and discharging efficiency of the first external device relatively high.

[0074] Optionally, the first external device may be the above-mentioned electronic device connected by a multifunctional cable. In this way, while the electronic device retains a single small interface type (such as a Type-c interface), different types of interfaces can be added through the docking station on the data cable. Thus, the second external device with different interface types can establish an effective connection with the electronic device through the interface of the docking station on the data cable.

[0075] The charging power supported by the first external device is the power for power transmission with the first external device based on the protocol adapted by the multifunctional cable to the first external device. Optionally, the charging power supported by the first external device may include the power supplied to the first external device or the power supplied to the first external device. These two powers may be the same or different and can be dynamically adjusted according to the charging protocol respectively.

[0076] For example, in the case where the multifunctional cable supports standard charging (such as 5 volts / 2 amperes) and fast charging protocol charging (such as 20 volts / 5 amperes), if the first external device supports fast charging protocol charging (such as 20 volts / 5 amperes), the charging power supported by the first external device is the power based on the fast charging protocol charging; if the first external device supports standard charging (such as 5 volts / 2 amperes), the charging power supported by the first external device is the power of standard charging.

[0077] Since the multifunctional cable is at least one sub-cable of the data cable and the multifunctional cable can perform power transmission with the first external device based on the charging power supported by the first external device, as the power of the first external device changes, the charging power supported by the first external device can change in the opposite direction.

[0078] The remaining power is the power difference between the charging power supported by the data cable and the charging power supported by the first external device. This power difference can be a difference value.

[0079] Taking the example of the multifunctional cable charging the first external device, the power that the data cable can carry is 120 watts, the input power of the data cable is 100 watts, and the data cable includes one multifunctional cable and two power supply cables; in the case where this multifunctional cable supports a charging power of 10 watts, the multifunctional cable performs standard charging (such as 5 volts / 2 amperes) and supplies power to the second external device with the remaining 90 watts of power; in the case where this multifunctional cable supports a charging power of 100 watts, the multifunctional cable charges according to the corresponding fast charging protocol (such as 20 volts / 5 amperes), and the remaining power is 0 watt, and no power is supplied to the second external device.

[0080] In this embodiment, the configuration of the multifunctional cable and the power supply cable during power transmission is different to preferentially use the multifunctional cable for charging. Thus, it is not necessary to evenly divide all the charging power input by the data cable, and the charging speed of the data cable can be improved.

[0081] In one embodiment, multiple sub-lines include sub-data lines that support data transmission; an expansion interface that supports data transmission and the sub-data lines are both connected to a data processing circuit; the data processing circuit is configured to support processing the data transmitted by the expansion interface and the sub-data lines.

[0082] The sub-data line is a sub-line that at least has a data transmission function. Optionally, the sub-data line with a data transmission function is a multi-functional line that supports both data transmission and power transmission. Optionally, there can be multiple sub-data lines so that multiple external devices can perform data transmission through the sub-data lines.

[0083] The expansion interface that supports data transmission is provided with a data transmission port that supports at least one protocol. The data transmission port is a port in the expansion interface that can perform data transmission. Optionally, the expansion interface that supports data transmission can be provided with multiple expansion interfaces that support data transmission so that multiple external devices can perform data transmission through the expansion interface. Optionally, multiple data transmission ports can support different protocols so that external devices using different protocols can all perform data transmission through the same data line.

[0084] The data processing circuit is a circuit provided inside the data line and can process the data transmitted by external devices. Since the data processing circuit is configured to support processing the data transmitted by the expansion interface and the sub-data lines, the data transmitted by the expansion interface and the sub-data lines can interact in the data processing circuit.

[0085] Optionally, the data processing circuit is provided with a processor and a memory: the processor is responsible for executing the software logic for management functions. They can be general microprocessors or embedded processors specifically designed for network management. The memory can store the configuration information of the device.

[0086] In this embodiment, both the expansion interface and the sub-data lines can perform data transmission, and the data transmitted through these two data channels can be processed by the data processing circuit in the data line. Therefore, on the basis of increasing the interfaces of the electronic device, the data line forms a medium for multiple external devices to perform data interaction. Thus, the data line has two data transmission channels and can perform data transmission with more external devices.

[0087] In an alternative embodiment, the data processing circuit includes a network management circuit and / or an audio-video processing circuit; the network management circuit and / or the audio-video processing circuit are connected to a data line controller, and the data line controller is also connected to a power management circuit; the network management circuit supports processing the data transmitted by the expansion interface and the sub-data lines to perform a wireless network connection; the audio-video processing circuit supports processing the data transmitted by the expansion interface and the sub-data lines to perform screen mirroring.

[0088] In a feasible embodiment, the data processing circuit includes a network management circuit. The network management circuit is connected to a data line controller, and the data line controller is also connected to a power management circuit. The network management circuit supports processing data transmitted by an expansion interface and sub-data lines for wireless network connection.

[0089] The network management circuit is a circuit that performs network processing based on data. Optionally, when the data line is connected to an external device through at least one of the expansion interface and sub-data lines, and the data transmitted by the external device reaches the network management circuit, the network management circuit performs network connection to the external device according to the data transmitted by the external device.

[0090] Optionally, the network management circuit may be integrated with a Wi-Fi circuit, a Bluetooth circuit, or other radio frequency circuits. In the case of performing wireless network connection, it is possible to save the Ethernet port, thus ensuring that the number of ports of the data line is more sufficient.

[0091] The data line controller can be used to control the power management circuit and the network management circuit respectively, and can ensure that the data of the two does not conflict.

[0092] In this embodiment, since the data processing circuit provided in the data line has a network management circuit, an external device can be connected to a wireless network through the data line, so that the external device can access more data, and the function of the external device for wireless network connection is extended. And through the data line controller, the power management circuit and the network management circuit are controlled respectively, and it can be ensured that the data of the two does not conflict.

[0093] In a feasible embodiment, the data processing circuit includes an audio-video processing circuit. The audio-video processing circuit is connected to a data line controller, and the data line controller is also connected to a power management circuit; the audio-video processing circuit supports processing data transmitted by an expansion interface and sub-data lines for screen mirroring.

[0094] The audio-video processing circuit is capable of performing audio-visual processing so that the data transmitted by the expansion interface and sub-data lines can be converted into data required for screen mirroring.

[0095] Optionally, the audio-video processing circuit is provided with an audio-visual processor. The audio-visual processor can convert the data transmitted by the expansion interface and sub-data lines into data adapted to the projector protocol for projection; or, the audio-visual processor can convert the data transmitted by the expansion interface and sub-data lines into data of a preset type for projection. Exemplarily, among the protocols adapted to High-Definition Multimedia Interface (HDMI), Video Graphics Array (VGA), or Universal Serial Bus (USB), the data transmitted by the expansion interface and sub-data lines can be processed according to a protocol adapted to the projector; or it can also be converted into data adapted to the HDMI protocol.

[0096] Optionally, when the data line is connected to an external device through at least one data channel of the expansion interface and the sub-data line, and the data transmitted by the external device reaches the audio and video processing circuit, the audio and video processing circuit group converts the external device according to the data transmitted by the external device for projection.

[0097] The data line controller can be used to control the power management circuit and the audio and video processing circuit respectively, ensuring that the data of the two does not conflict.

[0098] In this embodiment, the data processing circuit provided in the data line has an audio and video processing circuit. Therefore, when an external device needs to perform screen mirroring, the data line can assist the external device in performing screen mirroring, so as to assist the external device that needs screen mirroring to perform screen mirroring, enabling the external device to expand the screen mirroring function. Moreover, the data line controller is used to control the power management circuit and the audio and video processing circuit respectively, ensuring that the data of the two does not conflict.

[0099] In a feasible embodiment, the data processing circuit includes a network management circuit and an audio and video processing circuit; the network management circuit and the audio and video processing circuit are connected to the data line controller, and the data line controller is also connected to the power management circuit; the network management circuit supports processing the data transmitted by the expansion interface and the sub-data line for wireless network connection; the audio and video processing circuit supports processing the data transmitted by the expansion interface and the sub-data line for screen mirroring.

[0100] The data line controller is used to control the network management circuit, the audio and video processing circuit, and the power management circuit respectively, ensuring that the data of the three does not conflict.

[0101] In this embodiment, since the data processing circuit provided in the data line can simultaneously have an audio and video processing circuit and a network management circuit. At this time, on the one hand, the external device that needs to connect to the network can be connected to the wireless network through the data line, enabling the external device to obtain more data; on the other hand, the external device that needs screen mirroring is screen mirrored, enabling the external device to expand the screen mirroring function. Based on these two aspects, the appropriate data processing circuit can be selected for external devices with different requirements, and the external device can also perform screen mirroring while being connected to the wireless network. Moreover, the data line controller is used to control the network management circuit, the audio and video processing circuit, and the power management circuit respectively, ensuring that the data of the three does not conflict.

[0102] In an exemplary embodiment, such as Figure 3As shown, one side of the data cable docking station is equipped with a multi-function cable that can transmit data and provide power to electronic devices such as computers (PCs), mobile phones, and tablet computers (PADs). The other side of the data cable docking station is equipped with multiple power cables that come with the data cable, which can charge external devices connected to the power cables. The built-in power cables are limited to outputting power and have no data communication function. An expansion interface (HUB) is integrated in the middle of the controller, which includes a port that supports connecting a power adapter and a data transmission port. The data transmission port includes but is not limited to at least one of the following interfaces: USB, type-c, HDMI, DVI, DP, VGA, etc., and can be used for devices with different types of connectors. The electronic device connected to the multi-function cable is charged first. When the electronic device has excess charging power, the built-in power cable on the right side will distribute power to the device connected to the power cable. In addition, a HUB controller can also be included to control communication transmission and charging.

[0103] In an exemplary embodiment, Figure 4 As shown, the data line controller provided in the expansion dock is a HUB controller, which includes a main controller, and a network management circuit, an audio and video processing circuit, and a power management circuit controlled by the main controller; and the expansion interface of the expansion dock includes but is not limited to at least one of the interfaces such as USB, Type-C, HDMI, DVI, DP, VGA, and RJ45. Among them, the main controller communicates data with the audio and video management circuit and the network management circuit through multiple interfaces; the network management circuit supports processing data transmitted by the expansion interface and the sub-data line to perform wireless network connection; the audio and video processing circuit supports processing data transmitted by the expansion interface and the sub-data line to perform screen projection. The power management circuit includes a power controller, a protocol controller, and a power supply controller, and the power controller is connected to the protocol controller and the power supply controller; wherein the protocol controller is configured to obtain protocol data of an external device; the power controller is configured to control the power supply controller according to the protocol data; the power supply controller is configured to control the power management circuit to supply power to the external device, or to receive power from the external device.

[0104] Based on this, the data cable integrates an expansion interface, realizing the function of a hub or other expansion dock. This facilitates the miniaturization of terminal devices such as laptops, requiring only a single interface (such as Type-C) and avoiding damage to the electronic device interface caused by repeated plugging and unplugging. At the same time, there is no need for an additional dedicated expansion dock. Only a single data cable is needed to meet multi-functional needs, making it easy to carry. The data cable can power multiple devices with different charging connectors (Type-C, Lightning, Micro-B, etc.). The power adapter is connected directly to the data cable without occupying the original data cable connector, meeting the power supply needs of multiple devices with one cable, allowing more devices to be connected.

[0105] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0106] The above-described embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
