As shown in FIG. 4, the drawer-type pad 53 is adjacent to the docking slot 53-1 and the docking slot 53-1 for docking the mobile terminal when it is slid outward and is in contact with the mobile terminal. And a contactless charging pad 53-2 for performing charging.

One side of the contactless charging pad 53-2 is provided with a paging function key for outputting a predetermined signal to the mobile terminal. When the paging function key is pressed, a paging signal is output to a specific mobile terminal (eg, a terminal lost in the house) so that the user can easily find the terminal.

A secondary coil is provided inside the contactless charging pad 53-2. When the drawer-type pad is slid and opened, an initial current is supplied to the secondary coil and operated.

Therefore, when the mobile terminal is seated on the contactless charging pad 53-2, an induced electromagnetic force is generated in the primary coil of the mobile terminal by the current flowing through the secondary coil, and an induced current is generated by the electromagnetic force, thereby generating the mobile terminal. Is charged.

The docking station is wired connected to the mobile terminal through the interface unit of the support unit 54 (wired communication) or wirelessly connected to the mobile terminal through the communication unit (wireless communication: short-range communication).

Referring to the accompanying drawings, the operation of the drawer-type docking station of the mobile terminal according to an embodiment of the present invention configured as described above is as follows.

The docking station performs a function of displaying predetermined information on a monitor when the mobile terminal is not docked.

For example, the docking station may display information received from an external device (or an external memory) through a USB port, an A / V output port, an HDMI port, an SD card slot, and Bluetooth included in an interface unit. Display the digital frames, schedules and calendars, screensavers, etc., as well as useful data such as cooking recipes.

Thereafter, the drawer-type pad provided at the bottom of the docking station is opened (sliding), and when the user places the mobile terminal in the docking slot of the drawer-type pad, docking is performed between the mobile terminal and the docking station. At this time, the controller 180 detects the docking based on the contact between the docking slot and the mobile terminal or detects the docking based on the start of the contactless charging.

Once the docking is detected, the controller 180 performs a contactless charging operation with the docking system and synchronizes the mobile terminal docking station screen. The operations may be performed simultaneously or sequentially.

When the mobile terminal is docked at the docking station, an induced current is generated by the primary coil of the mobile terminal and the secondary coil of the drawer pad to start contactless charging of the mobile terminal. In this case, the contactless charging is superior to the contactless charging efficiency when the mobile terminal is placed in close contact with the drawer-type pad surface than when the mobile terminal is placed obliquely in the docking slot.

As described above, contactless charging of a mobile terminal using a docking station may be used to charge a battery of various small devices as well as a portable terminal. Thus, the user may simply charge the mobile terminal with the docking station at home or in the office.

In addition, the controller 180 of the mobile terminal performs wireless communication with the docking station using short-range communication to synchronize the mobile terminal and the docking station. In other words, when the mobile terminal is docked to the docking station, the docking station is automatically synchronized with the mobile terminal so that the screen of the monitor is synchronized with the screen of the mobile terminal.

Accordingly, the synchronization function enables the user to enjoy multimedia through a larger size monitor provided in the docking station beyond the screen size limitation of the mobile terminal.

5 is an example of a docking system in which a mobile terminal is docked to a docking station.

As shown in FIG. 5, when the mobile terminal is docked at the docking station, contactless charging is performed between the mobile terminal and the docking station, and the same screen as the screen of the mobile terminal is displayed on the monitor of the docking station through synchronization. In addition, the voice output through the mobile terminal is output through the speaker of the docking station.

Thereafter, the user can control the mobile terminal to watch the desired multimedia (text, picture, video, etc.), and the video and audio of the watching multimedia are output through the monitor and the speaker of the docking station. Control of the mobile terminal includes touch input to the mobile terminal or key input via a wireless keyboard.

FIG. 6 is a schematic diagram of the docking station illustrated in FIG. 5.

FIG. 6 illustrates an example of transferring data stored in a memory of a mobile terminal to an internal memory (large memory) of a docking station by being connected by wire through a USB port, and generated by a secondary coil of a docking system when an external power source (AC) is connected. An example is shown in which the current is charged to the battery of the mobile terminal through the stop value.

7 is a flowchart illustrating a docking control method of a mobile terminal according to an embodiment of the present invention.

When the mobile terminal is not docked, the docking station performs an on-screen function of displaying data stored in the internal memory on a monitor according to a user input.

Then, when the user slides the drawer-type pad and puts the mobile terminal on the docking pad, the docking station generates an electric current by generating a current in the secondary coil of the docking station to generate an electromagnetic force and the primary coil of the mobile terminal by the electromagnetic force. When the contactless charging is started, the controller 180 of the mobile terminal synchronizes the screen of the display unit 151 with the screen of the monitor. (S12).

Accordingly, the multimedia data displayed on the mobile terminal is displayed on the docking station monitor and the sound related to the multimedia data is output through the speaker of the docking station.

Thereafter, the docking station is controlled according to a user input through the mobile terminal to display multimedia data transmitted from the mobile terminal (S13).
