Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are conceptual views illustrating a sliding device of a portable terminal in a state in which the portable terminal is closed and the portable terminal in an open state, respectively, and FIGS. 3 and 4 are slides of the portable terminal according to the present invention, respectively. 5 is a conceptual diagram illustrating a method of opening or closing, FIG. 5 is a flowchart illustrating a slide control of a portable terminal according to an embodiment of the present invention, and FIG. 6 is a circuit diagram according to another embodiment of the present invention.

As shown in the figure, the present invention, the magnet structure 10 is installed on the first body 1 to have the N pole and the S pole in the slide direction, respectively, and the magnet 10 in a state in which the terminal is open or closed; It consists of an electromagnet 20 which is installed on the second body 2 to be attached to either polarity.

At this time, the magnet structure 10 is the first magnet 11 having the N pole and the S pole in the direction perpendicular to the slide direction, and the second magnet and the first magnet 11 and the second that is installed at a predetermined interval spaced apart It consists of a magnet 12.

On the other hand, in another embodiment, the magnet structure 10 is composed of one magnet in which the N pole and the S pole are arranged side by side in the slide direction, or two magnets having only N pole or S pole in one magnet. It can be composed of different monopole bodies.

The electromagnet 20 is formed on the second body 2 and is magnetized to have both polarities (N pole, S pole) in a direction perpendicular to the slide direction when current flows, and returns to its original state when the current is cut off. As a temporary magnet, both polarities change according to the flow direction of the applied current.

At this time, when the electromagnet 20 is made of a ferromagnetic material having a property of sticking to the magnet, such as iron, cobalt, nickel, and alloys thereof, even if the electric current to the electromagnet 20 is blocked, the electromagnet ( By attaching 20), it is possible to fix the position without flowing in the state in which the terminal is opened and closed.

In addition, the electromagnet 20 is installed between the two poles (N pole, S pole) when the end is located in the intermediate position of the magnet structure 10 in the state that the terminal is fully opened and closed as shown in FIG. Will have a sliding direction in the more smooth sliding operation will be possible. At this time, the length of the electromagnet 20 is preferably applied equal to the length of the terminal sliding and the length of the first and second magnets (11, 12).

Hereinafter, a slide method of a slide type portable terminal according to the present invention will be described in detail with reference to FIGS. 3 and 4. At this time, the polarities (N, S) of the first magnet, the second magnet (11, 12) and the electromagnet 20 shown in Figs.

As shown in FIG. 3, the slide-type portable terminal according to the embodiment of the present invention includes a first magnet 11 having an N pole in the first body 1, and a second magnet 12 having an S pole. It is arranged side by side in the slide direction, the second body 2 is provided with an electromagnet 20 in a position corresponding to the second magnet 12 in the closed state.

When the user makes a key input in the closed state of the terminal for use of the slide type portable terminal configured as described above, after determining the closed state of the terminal by the controller, a current is applied to the electromagnet 20 so that the terminal can slide open. Will be applied.

Accordingly, the electromagnet 20 to which the current is applied is pushed to each other by forming a pole (S pole) having the same contact surface with the second magnet 12 corresponding to the state in which the terminal is closed, the opposite pole (N) The first magnet 11, which is the pole), is pulled together and the terminal is automatically opened.

On the other hand, after the terminal is opened, the power is automatically cut off so as to minimize battery consumption. The electromagnet 20 made of ferromagnetic material is made of magnetism due to the inherent property of attaching to the magnet even when the electrode is lost by blocking current. By sticking to one magnet 11, the terminal can be kept open.

Thereafter, when the user runs out of the terminal and reapplies a key input to close the terminal, after determining the open state of the terminal by the control unit, current flows to the electromagnet 20 so that the terminal can be slide-closed. In other words, the current is applied.

When the current is applied to the electromagnet 20 by changing the flow of current, as shown in FIG. 4, the electromagnet 20 has an N pole whose contact surface is the same pole as that of the first magnet 11 again. The first magnet 11 is pushed with each other, and the second magnet 12, which is the opposite pole (S pole), is pulled with each other, thereby automatically closing the terminal.

5 is a flowchart illustrating a slide control of a slide type portable terminal according to the present invention.

A slide control method according to the present invention includes a first step of detecting the presence of a key input of the user; A second step of determining an open / closed state of the terminal when a user inputs a key; And a third step of applying a current by controlling a flow direction of the current applied to the electromagnet 20 so as to operate in the opposite direction to the terminal open / closed state recognized in the second step.

Meanwhile, the slide control method cuts off the current applied to the electromagnet 20 after the opening / closing state of the terminal is changed by the third step, or after a current is applied and a predetermined reference time T1 passes. It may further comprise a fourth step.

FIG. 6 is a circuit diagram according to another embodiment of the present invention. In detail, FIG. 6 is a circuit diagram when the electromagnet 20 is not a ferromagnetic material.

As such, when the electromagnet 20 is not a ferromagnetic material, since the power supply unit 30 should always be connected to the electromagnet 20, it is required to minimize current consumption by the electromagnet.

Accordingly, in one embodiment of the present invention, when the slide operation signal is applied from the key input unit 40, the control unit 50 determines the open / closed state of the current terminal, so that the slide operation can be performed opposite to the open / closed state of the current terminal. The current flow in the power supply unit 30 is controlled to apply a current to the electromagnet 20.

Then, after the terminal slides open and close, the circuit diagram is configured so that the current coming from the electromagnet 20 can be used in the other component 60 is required power.

As described above, the present invention, it is possible to automatically perform the sliding operation of the terminal, there is an effect that can be improved to improve the convenience of the user and to prevent the arbitrary flow during the opening and closing operation of the terminal.                     

In addition, in the opening and closing operation of the terminal, there is no wear or the like due to the period of use, so that the initial performance can be maintained permanently, thereby increasing the durability of the portable terminal.
