The present invention relates to a portable terminal, and more particularly, to a slide device of a portable terminal that simplifies the structure for the slide movement of the cover relative to the main body.

In general, a portable terminal (hereinafter, referred to as a "terminal") such as a mobile phone or a PDA is a device for wireless communication such as a call or data transmission and reception, and a body provided with a keypad and a cover provided with a liquid crystal for a display can be opened and closed with each other. To be combined.

Such terminals are generally classified into a bar type, a flip type, a folder type, a slide type, and the like according to the appearance or the opening / closing structure of the cover for the main body.

The bar type has a structure in which an input unit and a transceiver are installed in one main body, and the flip type has a structure in which a flip is provided at the bottom thereof to open and close the main body in which the input unit and the transceiving unit are installed. The cover is opened and closed while rotating at a predetermined angle with respect to the main body with the hinge means formed in the slide type, the slide is opened and closed while sliding the cover with respect to the main body by a guide means formed respectively corresponding to the main body and the cover. It is a structure.

Among these various terminals, the slide type terminal has a structure in which the cover slides by a predetermined length in the longitudinal direction of the terminal with respect to the main body. Accordingly, the length of the terminal is reduced, thus making it easy to carry, and having a wider display liquid crystal, and opening and closing of the terminal is easier than the folding type.

However, the conventional slide-type terminal has a lot of inconveniences in use due to strong passiveness when the cover slides with respect to the main body, and there is a problem that scratches occur frequently due to severe friction between components of the slide device when sliding.

Accordingly, although a slide device using a magnet has been disclosed in the related art, the conventional structure is formed in a form in which the magnet is in close contact with the magnet, so when the cover is opened to the main body, the magnets are exposed to the outside so that external foreign substances are exposed. The back is frequently attached to the magnet, and when such foreign matter accumulates, there is a problem of shortening the life of the slide apparatus.

The present invention is to solve this problem, using the principle of permanent magnets that push the same polarity and pull the other polarity each other to slide the mobile plate semi-automatically to provide a convenience for use in the slide device of the portable terminal The purpose is to provide.

In addition, the present invention has another object to provide a slide device of a portable terminal to minimize the foreign matter to be attached to the magnet by the polarity of the magnet and the magnet.

An object of the present invention described above, in a portable terminal that the cover slides on the main body, is fixed to the cover, provided with a slide rail in the longitudinal direction at both ends, the auxiliary rail is formed in the center parallel to the slide rail A moving plate having a moving magnet coupled to the auxiliary rail; It is fixed to the main body, both ends are formed with a slide groove for inserting the slide rail, is located between the two slide rail and the auxiliary rail rotatably coupled to the pair of rotating magnets to impart a repulsive force to the moving magnet portion It is achieved by a slide device of a portable terminal comprising a fixed plate.

Hereinafter, the slide device of a portable terminal according to the present invention will be described with reference to the accompanying drawings.

1 is an exploded perspective view showing a portable terminal equipped with a slide device according to the present invention, Figure 2 is an exploded perspective view of the slide device applied to Figure 1, Figure 3 is a cross-sectional view of the slide device applied to FIG.

As shown in FIG. 1, the slide device S according to the present invention is interposed between the main body 1 and the cover 2 of the portable terminal, and the sliding distance of the cover 2 on the main body 1 is allowed. It is configured to slide in the longitudinal direction within the range.

As shown in FIGS. 2 and 3, the slide device S is fixed to the fixed plate 10 fixed to the main body 1 provided with a keypad and the cover 2 provided with a liquid crystal display device. It is composed of a moving plate (20).

The fixed plate 10 has slide grooves 11 that are bent in a "c" shape in the longitudinal direction at both ends thereof.

Slide rails 21 are formed at both ends of the movable plate 20 to be coupled to the slide grooves 11 so as to slide, and an auxiliary rail 22 is formed at the center thereof.

On both sides of the fixing plate 10, shaft holes 12 are formed on the same line around the auxiliary rails 22, and a pair of rotating magnets 30 are coupled to the shaft holes 12 so as to be symmetrical with each other. .

Each of the rotor magnets 30 is a disc-shaped rotary wheel 31 rotatably coupled to the fixed plate 10 so as to contact the slide rail 21 and the auxiliary rail 22, and the rotary wheel 31. Consists of a circular permanent magnet 33 is mounted on, the rotary shaft 32 is protruded vertically so as to be rotatably coupled to the shaft hole 12 in the center of the rotary difference 31.

And the outer side of the rotary car 31 is coupled to the elastic body 34 so as to reduce the contact impact when the contact with the stopper 24 of the movable plate 20, the elastic body 34 is a predetermined elastic force It is preferable that it is made of a synthetic resin having, for example, rubber or urethane material.

Therefore, the elastic body 34 is in contact with the stopper 24 at the sliding completion point of the moving plate 20, the smooth stop operation of the moving plate 20 is possible.

On the other hand, inside the auxiliary rail 22, a bar-shaped moving magnet part 40 having a predetermined length is fixedly coupled to generate a repulsive force with respect to the rotating magnet part 30, and the moving magnet part 40 The combined movement plate 20 is made of a smooth sliding and easy to the fixed plate 10 is coupled to the rotating magnet portion 30.
