The fixing plate 311 is fixed to the lower surface of the upper body 210 and the moving plate 312 is coupled to the fixing plate 311 so as to be slidable relative to each other. A slide rail 315 having a groove is formed in the moving plate 312. The side of the fixing plate 311 is inserted into the slide rail 315 and moved.

A spring module may be provided between the slide rail 315 and the fixing plate 311 to implement semi-automatic movement of the upper and lower bodies 210 and 220 when the slides are moved relative to each other. The spring module is provided with a spring inside and is formed in such a manner that the spring is compressed according to the relative movement of the fixed plate 311 and the moving plate 312 to generate an elastic force. When the upper body 210 is slid by the user for a predetermined interval with respect to the lower body 220 in the closed state (or the opened state), the upper body 210 is automatically moved by the elastic force provided by the spring module Slide.

The moving plate 312 is formed with a hinge portion 314 and the moving plate 312 is rotatably connected to the lower body 220 through the hinge portion 314. A support plate 223 is fixed between the upper case 221 and the lower case 222 of the lower body 220 and a hinge connection part 224 is formed on the support plate 223.

The mounting portions 316 may be formed at both ends of the support member 313 in pairs. The mounting portion 316 may be formed to protrude upward from the support member 313 so as to be positioned on the side surface of the slide rail 315 formed on the moving plate 312. A portion of the tilting unit 320 Is formed so as to have a shape of "? ' The mounting portion 316 can be formed by bending the metal plate several times.

Although the slide unit 310 includes the stationary plate 311, the moving plate 312, and the support member 313, the slide unit 310 may be mounted on the moving plate 310 without the stationary plate 311, (312) and the support member (313). In this case, the moving plate 312 may be slidably connected directly to the upper body 210, and the upper body 210 may have a structure connected to the slide rail 315. At this time, the moving plate 312 may be referred to as a 'slide member' in that the moving plate 312 is slidably connected to the upper body 210.

The tilting unit 320 is connected to the lower body 220 to support the slide unit 310. The tilting unit 320 is a structure for applying a rotational force to the slide unit 310 so that the slide unit 310 rotates about the hinge portion 314.

The tilting unit 320 may include a link member 321 and a turning force providing unit 322.

One end of the link member 321 is connected to the mounting portion so as to apply a rotational force to the support member 313.

The link torque providing portion 353 may be realized in the form of a torsion spring module that generates a torque by providing a torsion spring therein. At this time, both ends of the rotational force providing portion 353 are connected to the lower body 220 and the link member 321, respectively.

The link member 321 rotates as the torque providing portion 322 generates torque and the link member 321 rotates to the supporting member 313 in such a manner that the supporting member 313 tilts in accordance with the rotation of the link member 321 .

Between the link member 321 and the mounting portion 316, a guide portion 330 for guiding the tilting operation of the support member 313 is provided. The guide portion 330 may include a guide slot 331 formed in the mounting portion 316 and a guide protrusion 332 formed in the link member 321.

The guide protrusion 332 is inserted into the guide slot 331 and the guide protrusion 332 moves on the guide slot 331 in accordance with the rotation of the link member 321. The guide protrusion 322 serves to transmit the rotational force of the link member 321 to the support member 313. Here, the guide slot 331 may have a certain length in one direction, and the lengthwise direction of the guide slot 331 may be formed to be inclined by a certain angle with respect to the horizontal direction. At this time, the inclined angle of the guide slot 331 in the longitudinal direction determines the tilting angle of the support member 313.

The mobile terminal is further provided with a cover portion 340 for covering a flexible circuit board (FPCB) for electrical connection between the upper and lower bodies 210 and 220 in a tilted state of the upper body 210.

Accordingly, the moving plate 312 supported by the supporting member 313 is rotated around the hinge 314 to be tilted, and the fixing plate 311 is tilted while sliding on the moving plate 312 do. Accordingly, after the first section, the upper body 210 is slid with respect to the lower body 220 and a tilting operation is performed. The section from the start of the tilting of the upper body to the completion of the movement of the upper body is referred to as' 2 section ".

The tilting operation of the upper body 210 is automatically performed by the rotational force of the rotational force providing portion 322. In the second section, the sliding motion of the upper body 210 is automatically performed by the elastic force of the spring module.

In the second section, the rotation restraint of the cover 341 by the upper body 210 is released, and the cover 341 is rotated and raised by the rotational force provided by the spring 342.

The sliding operation and the tilting operation of the upper body 210 continue in the second section, and the mobile terminal is switched to the opened state as shown in FIG. 6D.

The operation in which the mobile terminal is closed from the opened state is performed in the reverse order of the above description. The user pushes the upper body to allow the upper body to be laid and slid at the same time. That is, in the second section, the upper body 210 rotates in the opposite direction of the tilting direction and simultaneously slides, and when the upper body 210 passes the dead point of the spring module in the first section, it moves semi-automatically. At this time, in the second section, the upper body 210 pushes the cover 341 so that the cover 341 is laid out.
