[0047] Example 1:

[0048] like Figure 1 As shown, this embodiment provides a multi-interface expansion dock, including: a compatibility interface 01 for compatibility with at least two types of connectors, a connector type detection module 011, a controller 02 configured to support a mode of at least one of the at least two types of connectors, a switch switching module 03, and a mode switching module 04 for switching interface modes.

[0049] The compatible interface 01 is equipped with a connector type detection module 011; the connector type detection module 011 is connected to the controller 02;

[0050] Specifically, the connector type detection module 011 is configured to detect the type of the interface connected to the compatible interface 01 and send a signal corresponding to the detection result to the controller 02.

[0051] The controller 02 is electrically connected to the switch switching module 03, and the switch switching module 03 is electrically connected to the mode switching module 04 and the compatible interface 01, so as to control the electrical connection between the controller 02 and the mode switching module 04 or the electrical connection between the controller 02 and the compatible interface 01 through the switch switching module 03.

[0052] The mode switching module 04 is electrically connected to the compatible interface 01.

[0053] After receiving the signal corresponding to the detection result, the controller 02 controls the switch switching module 03 to realize the conduction of the controller 02, the switch switching module 03 to the compatible interface 01, or the conduction of the controller 02, the switch switching module 03 and the mode switching module 04 to the compatible interface 01.

[0054] Specifically, when the result of the detection is that the interface connected to the compatible interface 01 is of a type that the controller 02 is configured to support, the controller 02, the switch switching module 03 and the compatible interface 01 are connected.

[0055] On the contrary, the controller 02, the switch switching module 03 and the mode switching module 04 are connected to the compatible interface 01; specifically, the mode switching module 04 switches the mode to switch between the mode corresponding to the interface connected to the compatible interface 01 and the mode configured by the controller 02 to support, thereby realizing the compatibility of the interface connected to the compatible interface 01.

[0056] The embodiment provides an expansion dock supporting multiple interfaces. The connector type detection module 011 arranged on the compatible interface 01 detects and identifies the type of the connector inserted into the compatible interface 01 and sends a detection signal corresponding to each type of connector to the controller 02. The controller 02 generates a corresponding control signal according to the detection signal of each type of connector to control the switch switching module 03. The switch switching module 03 makes the controller 02 electrically connected to the mode switching module 04 or makes the controller 02 directly electrically connected to the compatible interface 01 according to the control signal, wherein the mode switching module 04 is electrically connected to the compatible interface 01. Through the cooperation of the interface type detection module, the controller 02, the switch switching module 03 and the mode switching module 04, the compatible interface 01 mode output is automatically switched to adapt to the signal of the inserted interface type. The support for at least two types of interfaces is realized.

[0061] Different mode switching modules 04 have different compatible interfaces 01 for electrical connection.

[0062] Specifically, in this solution, the compatible interface 01, the connector type detection module 011, and the switch switching module 03 form a compatible module; and in order to better accommodate more interfaces, the compatible module in this solution can be one group or at least two groups; each group of compatible modules can share one controller 02.
