Docking station for simultaneously establishing connections from a smartphone to an external display and USB device

1. A docking station comprising:

a controller;

a first switch, coupled to the controller;

a wireless communication module, coupled to the controller, and being capable of establishing at least one wireless link with an external portable electronic device;

a universal serial bus (USB) hub, coupled to the controller for linking a USB device;

a relay, having a control terminal and multiple rows of change-over contacts, wherein each row of change-over contacts has a common terminal, a normally-open contact and a normally-closed contact, and the control terminal and the normally-open contacts are coupled to the controller;

a first connector, coupled to the common terminals of the relay for connecting the external portable electronic device;

an audio/video (AV) converter, coupled to the normally-closed contacts of the relay for converting first AV data into second AV data; and

a second connector, coupled to the AV converter for outputting the second AV data to an external display;

wherein the relay switchably connects the first connector to either the AV converter or the controller, the relay normally connects the first connector to the AV converter for transferring the first AV data from the external portable electronic device to the external display through the AV converter when the first switch is not operated, while the first switch is being operated, the controller controls the relay to switch through the control terminal, then the controller links the external portable electronic device connected to the first connector and functions as a virtual USB device of the external portable electronic device to obtain information thereof, the first connector is switched to serve as a USB port, the wireless communication module establishes the at least one wireless link with the external portable electronic device, finally the wireless communication module makes data transfer between the USB device and the external portable electronic device through the at least one wireless link, and the relay restores to connect the first connector to the AV converter after the at least one wireless link has been established and the first switch is not operated.
