[0004] According to one aspect of the present invention, a charging dock is provided, comprising: a liquid cooling module, a grounding terminal, a connector, and a power terminal. The liquid cooling module is used to cool the charging dock and includes a cooling tank for containing coolant. The connector electrically connects the cooling tank of the liquid cooling module and the grounding terminal. When coolant flows out of the liquid cooling module, the coolant contacts the power terminal, thereby establishing electrical conductivity between the power terminal and the grounding terminal via the cooling tank.

[0005] According to an exemplary embodiment of the present invention, the liquid cooling module further includes: an extension member, an inlet pipe connector, and an outlet pipe connector. The extension member is connected to the cooling tank. The inlet pipe connector and the outlet pipe connector are disposed on one side of the cooling tank and connected to the cooling tank. The coolant flows into the cooling tank via the inlet pipe connector and flows out of the cooling tank via the outlet pipe connector. The connector connects the extension member and the grounding terminal.

[0006] According to another exemplary embodiment of the present invention, the extension and the power terminal are disposed on the opposite side of the cooling tank, opposite to the inlet pipe connector and the outlet pipe connector.

[0007] According to another exemplary embodiment of the present invention, the charging dock further includes a housing. The liquid cooling module, the grounding terminal, the connector, and the power terminal are all disposed within the housing. The liquid inlet connector, the liquid outlet connector, the grounding terminal, and the extension all extend longitudinally along the housing.

[0008] According to another exemplary embodiment of the present invention, the connector extends along the height direction of the housing and passes through the extension along the height direction to connect with the grounding terminal.

[0009] According to another exemplary embodiment of the present invention, the extension member is provided with an extension member through hole, and the connector can pass through the extension member through the extension member through hole, thereby connecting the extension member to the grounding terminal.

[0010] According to another exemplary embodiment of the present invention, the charging dock further includes a grounding bus. The extension is located between the grounding terminal and the grounding bus, and the grounding bus is connected to the grounding terminal via the connector.

[0011] According to another exemplary embodiment of the present invention, the grounding busbar is provided with a grounding busbar through hole, and the connector can pass through the grounding busbar through hole, thereby connecting the grounding busbar to the grounding terminal.

[0012] According to another exemplary embodiment of the present invention, the grounding bus extends laterally in a direction perpendicular to both the height and the longitudinal direction.

[0013] According to another exemplary embodiment of the present invention, the grounding terminal has a semi-cylindrical connecting end, on which a through grounding hole is formed. The connecting end has a flat contact surface, and the connector threadedly fastens the extension and the grounding busbar to the flat contact surface of the connecting end.

[0015] According to another exemplary embodiment of the present invention, the charging dock further includes a grounding cable connected to the grounding bus and extending from one side of the housing.

[0016] According to another exemplary embodiment of the present invention, the liquid cooling module further includes an insulating and thermally conductive layer disposed outside the cooling box. The insulating and thermally conductive layer is in thermal contact with the power terminals and electrically isolates the cooling box from the power terminals.

[0017] According to another aspect of this utility model, a charging dock leakage detection system is provided, comprising: a charging dock as described in any of the above claims and a leakage detection circuit. The leakage detection circuit is connected to the power cable and ground cable of the charging dock and is used to detect the resistance between the power terminal and the ground terminal of the charging dock. When coolant flows out of the liquid cooling module, the resistance detected by the leakage detection circuit is less than a predetermined value.

[0018] According to an exemplary embodiment of the present invention, the charging dock leakage detection system further includes a control circuit for controlling the power supply to supply power to the power terminals of the charging dock. When the resistance detected by the leakage detection circuit is less than a predetermined value, the control circuit cuts off the power supply loop between the power supply and the power terminals of the charging dock to stop supplying power to the power terminals of the charging dock.

[0019] In the foregoing exemplary embodiments of this utility model, the connector in the charging dock connects the grounding terminal and the liquid cooling module, so that when the coolant flows out of the liquid cooling module, the coolant contacts the power terminal, thereby creating electrical continuity between the power terminal and the grounding terminal. When the coolant flows out of the liquid cooling module, the resistance detected by the leakage detection circuit is less than a predetermined value, thus determining that there is a coolant leak. The charging dock and charging dock leakage detection system of this utility model have a simple structure and can effectively prevent short circuits and fires, ensuring user safety.
