4 is an exploded perspective view of the slide module shown in FIG. 5 and 6 are a perspective view and an exploded perspective view of an elastic force providing module according to the first embodiment of the present invention.

An elastic force providing module 300 is mounted between the first slide member 210 and the second slide member 220 to provide an elastic force to the first slide member 210 and the second slide member 220 when they are moved relative to each other.

The elastic force providing module 300 according to the present embodiment includes a first arm member 310, a second arm member 320, and a support member 330.

One end of the first arm member 310 is rotatably connected to the first slide member 210 by a first rotation point 313. One end of the second arm member 320 is rotatably connected to the second slide member 220 by the second rotation point 323. The first and second arm members 310 and 320 have a plate shape and may be formed of a metal material or a synthetic resin material that is elastically deformable.

The other end of the first and second arm members 310 and 320 is fixed to the support member 330 and the support member 330 is fixed to the first and second arms 310 and 320 so that the first and second arm members 310 and 320 can rotate relative to each other. Thereby supporting the members 310 and 320. The support member 330 may be formed in a plate shape supporting the other ends of the first and second arm members 310 and 320 and the other ends of the first and second arm members 310 and 320 may be disposed to face each other.

A first penetration pattern 311 and a second penetration pattern 321 may be formed at the other ends of the first and second arm members 310 and 320, respectively. The first and second through patterns 311 and 321 are for generating an elastic force due to the twist deformation of the first and second arm members 310 and 320 during the relative rotation of the first and second arm members 310 and 320.

At the other end of the first arm member 310, a first fixing part 312 having a fixed area for fixing to the supporting member 330 is formed.

The first and second through patterns 311 and 321 of the spiral shape are formed so that when the first and second arm members 310 and 320 rotate relative to the support member 330, that is, when the first and second arm members 310 and 320 When the first and second fixing portions 312 and 322 are twisted about the center, the gap is narrowed and returned to the original interval. Accordingly, rotational elasticity is generated at the other ends of the first and second arm members 310 and 320.

The first and second arm members 310 and 320 may be formed with teeth portions 340 that are engaged with each other when the first and second arm members 310 and 320 rotate. Accordingly, the first and second arm members 310 and 320 rotate together with the corresponding rotational angles when the first and second slide members 210 and 220 move relative to each other, thereby improving the dynamic stability of the elastic force providing module 300 .

7A to 7C are plan views of a slide module showing an operating state of an elasticity providing module according to an embodiment of the present invention. 7A to 7C sequentially show a process of switching the mobile terminal from the open state to the closed state.

In this state, when the user relatively slides the first body 101 and the second body 102 in a closed state, the second slide member 210 moves upward as shown in FIG. 7B. The first and second arm members 310 and 320 rotate about the first rotation point 313 in a counterclockwise direction and the first and second arm members 310 and 320 are rotated relative to the support member 330 .

The first and second arm members 310 and 320 are fixed to the support member 330 by the first and second fixing points 312 and 322. Since the first and second through patterns 311 and 321 are formed, (330).

The first and second arm members 310 and 320 are arranged such that the angle a between the first and second arm members 310 and 320 is reduced in the direction in which the first rotation point 313 and the second rotation point 323 approach each other, .

In this process, the first and second arm members 310 and 320 are twisted about the first and second fixing points 312 and 322, respectively. The distance between the first and second through patterns 311 and 321 is reduced due to the twist deformation of the first and second arm members 310 and 320. The first and second arm members 310 and 320 have the first rotation point 313, And the second rotation point 323 are apart from each other.

Deformation occurs in the first and second arm members 310 and 320 so that the interval between the first and second through patterns 311 and 321 is returned to the original interval. 7C, the first and second arm members 310 and 320 are moved in the direction in which the first rotation point 313 and the second rotation point 323 are away from the support member 330 by the rotational elastic force . The second slide member 220 is automatically moved to the upper portion of the first slide member 210 by this rotation.

Although the first and second through patterns 311 and 321 are formed on the first and second arm members 310 and 320 as a structure for generating a rotational elastic force on the first and second arm members 310 and 320, The present invention is not limited to this but may be embodied by forming a through pattern in at least one of the first and second arm members 310 and 320 and the support member 330. For example, it is also possible to form a through pattern on the support member 330 to generate a rotational elastic force on the first and second arm members 310 and 320.

In the above description, the first and second arm members 310 and 320 are connected to the first and second slide members 210 and 220, respectively. However, when the first and second bodies 101 and 102 are directly slidably connected In this case, the first and second arm members 310 and 320 may be directly connected to the first body 101 and the second body 102.
