Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail. However, the embodiments described below are merely to describe in detail enough to be able to easily carry out the invention by those skilled in the art to which the present invention pertains, thereby limiting the protection scope of the present invention It does not mean.

Figure 2 is a perspective view of a slide module according to an embodiment of the present invention, Figure 3 is a rear perspective view of the slide module shown in Figure 2, Figure 4 is a cross-sectional view of the main portion of the slide module shown in Figure 2, Figure 5 2 is an exploded perspective view of the slide module shown in FIG. 2.

2 to 5, the slide module includes a first plate 100, a second plate 200, an LCD bracket 300, and an elastic means 400.

The first plate 100 has a flat portion 110 and a bent portion 120 that is bent upward from both sides of the flat portion 110. At this time, one side of the bent portion 120 forms a cross-section of approximately 'c', and the other side forms a symmetrical cross section. Therefore, the guide grooves 130 are formed by the bent portion 120 at both sides of the flat portion 110.

The second plate 200 is coupled to slide relative to the first plate 100, and has a flat portion 210 and guide rails 220 formed on both sides of the flat portion 210. In addition, the second plate 200 is slidably coupled to the guide grooves 220 on both sides of the first plate 100 so as to slid relative to the first plate 100.

Here, the guide rail 220 of the second plate 200 is formed to form a step lower than the flat portion 210 on both sides of the flat portion 210, this is for the slimming of the slide module.

That is, as shown in FIGS. 3 and 4, when the guide groove 130 is formed by the bent portion 120 on both sides of the flat portion 110 of the first plate 100, the first plate 100 and the first plate 100 are formed. Since the elastic means 400 as described below are installed between the

planar portions

110 and 210 of the second plate 200, a gap to accommodate the thickness of the elastic means 400 must be maintained.

In this case, when both side guide rails 220 of the second plate 200 form a plane with the flat portion 210, the guide of the first plate 100 for the guide rail 220 of the second plate 200. In order to form the groove 130, the bent portion 120 of the first plate 100 must protrude to a predetermined height above the planar portion 210 and the guide rail 220 of the second plate 200. As a result, the thickness of the slide module becomes thick or the LCD cannot be applied at the maximum size, and thus the object of the present invention cannot be realized.

On the contrary, when the both guide rails 220 of the second plate 200 form a step lower than the flat part 210, the height of the bent part 120 of the first plate 100 may be minimized. In this way, the thickness of the slide module can be reduced.

In particular, when the guide rail 220 is coupled to the guide groove 130 of the first plate 100, the second plate 200 has a bent portion of the first plate 100 having an upper surface thereof. 120) It is preferable to form the same horizontal plane as the upper surface.

For reference, as shown in FIG. 4, the height may be approximately 1.5 mm from the bottom surface of the planar portion 110 of the first plate 100 to the top surface of the bent portion 120. In this case, the first plate 100 may be used. ) And the second plate 200 has a total thickness of 1.5 mm.

The LCD bracket 300 serves to receive the LCD, and has an accommodation portion 310 to which the LCD can be coupled. Here, the receiving portion 310 is preferably formed so that the four corners of the bottom surface of the LCD bracket 300 is bent upwards, whereby the CD can be inserted into the receiving portion 310.

And the LCD bracket 300 is fixedly coupled to the upper portion of the second plate 200, when the second plate 200 is sliding relative to the first plate 100 is sliding integrally with the second plate 200. .

Preferably, the LCD bracket 300 is formed to be wider than the width of the first plate 100, which is to combine the wide CD. In this case, the width of the LCD bracket 300 can be appropriately adjusted to the maximum width size according to the width of the first and second body (20, 30), in particular, the maximum width size that can be used for the LCD to the second body (30) Can be applied.

In addition, the guide holes 320 may be elongated in the longitudinal direction at both sides of the bottom surface of the LCD bracket 300, and the guide holes 320 may be inserted into a predetermined portion of the bent portion 120 of the first plate 100. The width of the first plate 100 is wider than that of the bent portion 120.

The reason for forming the guide hole 320 in the LCD bracket 300 is to provide a space for the bent portion 120 of the first plate (100). Therefore, when the second plate 200 and the LCD bracket 300 are relatively sliding relative to the first plate 100, the bent portion 120 of the first plate 100 is formed on the bottom surface of the LCD bracket 300. It can slide smoothly without contact.

In addition, recesses 330 of a predetermined depth may be formed long in both sides of the bottom surface of the LCD bracket 300, and in this case, guide holes 320 may be formed in the recesses 330. As such, even when the recess 330 is formed in the LCD bracket 300, since the guide hole 320 into which the bent portion 120 of the first plate 100 is inserted is formed, the first plate 100 is formed. The bent portion 120 can be slid without contacting the bottom surface of the LCD bracket 300.

In addition, the LCD bracket 300 may have a bracket sheet 340 attached to the upper surface of the depression 330, the bracket sheet 340 is formed to cover the depression 330 and the guide hole 320 do.

In this case, the bracket sheet 340 is preferably formed so that the thickness is the same as the depression depth of the depression 330, accordingly, when the bracket sheet 340 is attached to the upper surface of the depression 330, the LCD ( The bottom surface of the receiving portion 310 into which the 40 is inserted can be maintained in a flat state as a whole.

For reference, the bracket sheet 340 is preferably made of polyoxymethylene (POM) material.

The elastic means 400 serves to provide an elastic force so that the relative sliding of the first plate 100 and the second plate 200 is made semi-automatically, the first plate 100 and the second plate 200. Is provided between the planar portions (110, 210).

Specifically, one end of the elastic means 400 is rotatably coupled to the upper surface of the flat portion 110 of the first plate 100 and the other end is rotatably coupled to the lower surface of the flat portion 210 of the second plate 200. do.

Preferably, the elastic means 400 is, as shown in Figure 3 and 5, the first hinge member 410, the second hinge member 420, the support member 430, the support frame 440, elastic It may include a spring 450.

Here, the first hinge member 410 has a shape in which a plurality of through holes 412 are formed at one side and an opening (not shown) is formed at the other side, and has a substantially 'c' shape. The first hinge member 410 is rotatably coupled to the upper surface of the planar portion 110 of the first plate 100.

In addition, the second hinge member 420 has a shape substantially symmetrical with the first hinge member 410, and has a through hole 422 and an opening facing the through hole 412 and the opening of the first hinge member 410. (Not shown) is formed.

The second hinge member 420 is rotatably coupled to the bottom surface of the flat portion 210 of the second plate 200 and coupled to the first hinge member 410 so as to be relatively slidable. Face each other.

The support member 430 serves to fix the support frame 440 and has a substantially rectangular parallelepiped shape. Both ends of the support member 430 are slidably coupled along the inner surface of the opening of the first hinge member 410. For this purpose, the guide groove 416 is formed long in the inner surface of the opening of the first hinge member 410. .

A plurality of support frames 440 are provided to serve to support the elastic springs 450. The support frames 440 are fixed to each of the support members 430 and spaced apart from each other at predetermined intervals to be parallel to each other.

In this case, since the support frame 440 must be able to penetrate the through holes 412 and 422 of the first and

second hinge members

410 and 420, the support frame 440 has a diameter smaller than that of the through holes 412 and 422. In addition, the support frame 440 is extended to approximately the same length on both sides with respect to the support member 430.

The elastic spring 450 serves to provide an elastic force so that the relative sliding of the first hinge member 410 and the second hinge member 420 is semi-automatically, and surrounds the edge of the support frame 440 and supports one end thereof. It is fixed to the member 430 and the other end is fixed to the first or second hinge member 420

When the elastic spring 450 is compressed, the first hinge member 410 and the second hinge member 420 are slid relative to each other, and at the same time, the support member 430 is the first hinge member 410. Sliding inward of the first hinge member 410 along the guide groove 416 of the, the inner surface of the support member 430 and the first and

second hinge members

410, 420 is closer to the distance.

In this case, both ends of the support frame 440 pass through the through holes 412 and 422 of the first and

second hinge members

410 and 420, and the elastic spring 450 is formed of the support member 430 and the It is in a compressed state between the first and

second hinge members

410 and 420.

Accordingly, the elastic spring 450 is provided to the first and second hinge members (420, 420) to provide the elastic restoring force to be semi-automatically sliding.

On the other hand, in order to further reduce the thickness of the slide module may be provided with a receiving space for accommodating the thickness of the elastic means (400). That is, as shown in FIGS. 3 to 5, the opening 240 may be formed in the second plate 200. In particular, the opening 240 has an area and a depth in which the elastic means 400 can be accommodated. .

Accordingly, when the elastic means 400 is disposed in the opening 240 of the second plate 200, the entire thickness of the slide module can be reduced by at least the thickness of the elastic means 400.

6 is an operation of the slide module shown in FIG. With reference to this, it will be described the operation of the slide module according to an embodiment of the present invention.

For reference, the first plate 100 of the slide module is integrally slidable in combination with the first body. In addition, the second plate 200 to which the LCD bracket 300 is fixedly coupled is coupled to the second body to be integrally slidable.

In this case, since the plurality of elastic springs 450, one end of which is fixed to the support member 430 of the elastic means 400, provides the elastic restoring force to the first and

second hinge members

410 and 420. The second plate 200 is not slid upward in the drawing unless it is applied, thereby maintaining the closed state of the second body.

Subsequently, when an external force is applied to raise the second body upward, the first and

second plates

100 and 200 are relative sliding, and at the same time, the first body and the second body are relative sliding.

In this case, the first and

second hinge members

410 and 420 of the elastic means 400 are rotated relative to each other at the same time as one end coupled to the first and

second plates

100 and 200 are rotated, respectively, The 450 is compressed between the first and

second hinge members

410 and 420 and the support member 430.

And, as shown in (b) of FIG. 6, when the first plate 100 is slid to be positioned to approximately the center of the second plate 200, the elastic spring 450 is in a maximum compression state, and further external force is applied. If not applied, the first plate 100 may maintain a stopped state.

Subsequently, when a fine external force is applied downward or upward in the drawing, the first plate 100 is automatically downward of the second plate 200 as shown in FIG. 6C due to the restoring force of the elastic spring 450. The second body of the cellular phone is thus opened to the first body.

In this case as well, since the elastic spring 450 of the elastic means 400 provides elastic restoring force to the first and

second hinge members

410 and 420, the second body is in an open state unless an external force is applied. Is maintained.

On the contrary, when the second body of the open cellular phone is to be closed, the second body is closed semi-automatically when operated in the reverse order.
