Hereinafter, exemplary embodiments of a slide type portable terminal according to the present invention will be described in detail with reference to the accompanying drawings.

First, FIGS. 1 to 3 sequentially show the appearance and opening / closing operation of a slide type portable terminal according to an embodiment of the present invention. The slide type portable terminal of the present invention includes a main body case 1 and the main body case ( 1) the slide case sliding in the Y-axis direction up to a predetermined section, and the slide case opening in a state inclined at a predetermined angle with respect to the main body case (1) while performing a rotational movement in the Z-axis direction from the time passing through a certain section (2) And a hinge module installed between the main body case 1 and the slide case 2 to implement sliding and rotational movements of the slide case 2 with respect to the main body case 1.

The main body case 1 is a portion in which a main circuit board, a battery, a keypad and the like are embedded for various control of the mobile terminal, and the slide case 2 is a portion in which a display unit such as a liquid crystal display (LCD) is installed. However, the present invention is not limited thereto, and various components may be applied according to the function and purpose of the mobile terminal.

The slide case 2 is opened while sliding in the Y-axis direction by a predetermined distance in the closed state shown in FIG. 1 (see FIG. 2), and then fully moved to the rear end of the main body case 1 to operate the hinge module. As shown in FIG. 3, the rotary motion is automatically rotated in the + Z-axis direction and tilted with respect to the main body case 1 at an angle θ.

When the slide case 2 is to be closed with respect to the main body case 1, the slide case 2 may be rotated in the -Z axis direction and slid in the -Y axis direction at the same time as before.

4 to 13 show the configuration and operation of the hinge module for implementing the sliding motion and rotational motion of the slide case 2 with respect to the body case (1).

4 to 6, the hinge module of this embodiment has a pair of base plates 10 fixed to the rear of the main body case 1 by a predetermined distance, and the base plate 10 in the X axis. A tilting plate 30 rotatably connected about an extended hinge shaft 20 and fixed to a lower surface of the slide case 2 of the portable terminal, and both ends of the tilting plate 30 are Y-axis at both ends of the tilting plate 30. Sliding plate 50 is slidably coupled in the direction, and the torsion spring for tilting to be coupled to the hinge shaft 20 to apply an elastic force to the tilting plate 30 against the base plate 10 in the Z-axis direction 40 and two ends of which one end is fixed to the tilting plate 30 and the other end is fixed to the sliding plate 50 to apply an elastic force in the sliding direction to the sliding plate 50 with respect to the tilting plate 30. It is configured to include a sliding torsion spring (60).

The base plate 10 is formed of a substantially rectangular plate and is fixed to the body case 1 by fastening means such as screws. In addition, shaft insertion holes 11 are formed at both ends of one end of the base plate 10 to which the hinge shaft 20 is inserted and connected.

The tilting plate 30 is formed of an elongated rectangular plate that crosses the main body case 1, and has shaft inserts 31 connected to both ends of the hinge shaft 20 while being rotatably inserted. In addition, the both ends of the tilting plate 30 is formed with a guide portion 32 is bent in a '' 'shape, the guide portion 32 is a self-lubricating synthetic resin for guiding the movement of the sliding plate 50 Guide rail member 35 of the material is coupled. The guide rail member 35 has a slit 36 in which both ends of the sliding plate 50 are inserted in the Y-axis direction.

The tilting torsion spring 40 is supported with respect to the base plate 10 while one end is supported in contact with the base plate 10 and the other end is supported in contact with the tilting plate 30 as shown in FIGS. 7A and 7B. An elastic force is applied to the tilting plate 30 upward in the Z-axis direction. Therefore, the tilting plate 30 receives a force to rotate upward in the Z-axis direction about the hinge axis 20 by the elastic force of the torsion spring 40 for tilting.

In the state in which the slide case 2 is closed with respect to the main body case 1 as shown in FIG. 1, since the rotation of the slide case 2 is limited by the main body case 1, the tilting plate 30 moves in the + Z axis direction. Although it does not rotate, when the slide case 2 moves to the Y-axis direction and the front of the slide case 2 moves on the tilting plate 30, the slide case 2 moves to the main body case 1. Since the rotation is no longer limited by the tilting plate 30, the tilting plate 30 is inclined by rotating in the + Z axis direction about the hinge axis 20 by the elastic force of the torsion spring 40 for tilting (see FIG. 13).

4 and 5, the sliding plate 50 is formed of a rectangular plate having a size slightly smaller than that of the slide case 2 of the mobile terminal, and both ends thereof have a slit 36 of the guide rail member 35. ) And slides along the tilting plate 30 in the Y-axis direction.

The sliding torsion spring 60 provides a force to return to the initial position within the distance that the sliding plate 50 has not passed the transition point, and slides by providing an elastic force that biases the moving direction beyond the distance beyond the transition point. The case 2 is assisted to be opened and closed automatically with respect to the body case 1.

Meanwhile, a stopper for opening the slide case 2 to the outer end of each of the hinge shafts 20 while rotating in the + Z axis direction and then rotating in the -Z axis direction by external force to prevent falling or vibrating. 70 is fixed. In this embodiment, the stopper 70 has a triangular shape with a rear end protruding upward of the hinge shaft 20. In addition, as shown in FIG. 8, a track-shaped coupling hole 72 is formed at the front end of the stopper 70, and an outer end of the hinge shaft 20 forms a shape of the coupling hole 72. Coupling portions 22 chamfered in corresponding shapes are formed. Therefore, the stopper 70 remains fixed without rotation about the hinge shaft 20 by the coupling between the coupling hole 72 and the coupling portion 22.

9 and 10, guide grooves 2a inserted in correspondence with the stopper 70 are formed to extend in the Y-axis direction on the lower surface of the slide case 2.

The hinge module of this embodiment operates as follows.

1 and 11, when the user slides the slide case 2 to the rear (+ Y-axis direction) in a state in which the slide case 2 is closed with respect to the main body case 1, as shown in FIG. As described above, both end portions of the sliding plate 50 coupled to the slide case 2 are slid backward by the guide rail members 35 coupled to both ends of the tilting plate 30. At this time, the guide grooves 2a (see FIG. 9) formed on both lower surfaces of the slide case 2 are guided by the stopper 70.

While the slide case 2 slides in the Y-axis direction with respect to the main body case 1, the sliding torsion spring 60 is gradually compressed and expands from the point passing through the transition point, while the sliding direction of the sliding plate 50 moves. That is, by providing an elastic force in the + Y-axis direction so that the sliding plate 50 moves automatically in the subsequent section.

When the slide case 2 is moved completely to the rear, as shown in Figure 12, the front end of the slide case 2 and the sliding plate 50 is located on the tilting plate 30 and no longer the main body case ( Since the rotation is not limited by 1), the tilting plate 30 is rotated about the hinge axis 20 in the + Z axis direction by the elastic force of the torsion spring 40 for tilting. Accordingly, as shown in FIG. 13, the sliding plate 50 and the slide case 2, which are connected to the tilting plate 30, rotate in the + Z-axis direction to be inclined at a predetermined angle with respect to the main body case 1. do.

When the slide case 2 is inclined at a predetermined angle by rotating in the + Z axis direction, the lower surface of the slide case 2 is supported by the stopper 70 as shown in FIG. 10. Therefore, even when a force is applied perpendicularly to the surface of the slide case 2 during use, the slide case 2 is easily rotated to vibrate or fall by resisting the force applied to the slide case 2 in the vertical direction.

When closing the portable terminal in the open state, if the rear end of the slide case 2 is pushed forward (in the Y-axis direction), the slide case 2 slides forward in the reverse order as before, and gradually- It is closed while rotating in the Z-axis direction.

As described above, when the slide case 2 is opened by sliding a predetermined section with respect to the main body case 1, the slide case 2 is automatically + Z-axis by the action of the torsion spring 40 for tilting. It rotates in the direction and tilts at an angle. Therefore, the sliding motion and the rotational motion of the slide case 2 can be implemented with a very simple configuration.

14 to 18 show another embodiment of a hinge module of a slide type portable terminal according to the present invention. The hinge module of this second embodiment is the same in basic construction as the hinge module of the first embodiment described above, except that the slide module When the case 2 rotates with respect to the main body case 1, there is a difference in that an auxiliary tilting unit 80 for applying an elastic force in the rotational direction of the slide case 2 to assist the rotational movement is configured.

The auxiliary tilting unit 80 is installed inside the receiving groove 1a formed on both sides of the main body case 1, and is urged in the Z-axis direction to the slide case 2 at all times together with the torsion spring 40 for tilting. When the tilting plate 30 and the sliding plate 50 and the slide case 2 are rotated in the Z-axis direction with respect to the main body case 1 by the torsion spring 40 for tilting, the rotation is more smoothly. It helps to make it happen.

Referring to FIG. 17, in this embodiment, the auxiliary tilting unit 80 is rotatably installed in the main body case in the Z-axis direction, and the tilt lever 81 is installed so that one end thereof contacts the lower surface of the tilting plate 30. ), A housing 82 connected to one side of the tilt lever 81, and a shaft 83 installed in the housing 82 so as to extend in the X-axis direction and rotating about the X-axis with respect to the housing 82. And a compression spring 84 fitted to the shaft 83 to exert an elastic force in the X-axis direction, a first cam 85 coupled to one end of the shaft 83, and one side of the tilt lever 81. The second cam 86 is fixed to and rotated in the Z-axis direction by interaction with the first cam 85.

Curved cam surfaces 85a and 86a are formed on the surfaces of the first cam 85 and the second cam 86 that face each other, and the cam surface 85a and the first cam 85 of the second cam 86 are formed. By the curve of the cam surface 86a of), the first cam 85 is always forced to rotate in the Z-axis direction.

The tilt lever 81 has a body portion 81a having a groove 81c formed therein to which the first cam 85 is received and coupled to the body portion 81a, and has one end portion extended to the body portion 81a. The lever portion 81b is brought into contact with the lower surface. At the end of the lever portion 81b, the roller 87 rolling along the lower surface of the tilting plate 30 is freely rotated.

The auxiliary tilting unit 80 configured as described above is always at the upper side by the action of the compression spring 84 and the first cam 85 and the second cam 86 in which the tilt lever 81 is installed in the housing 82. When the rotation restriction of the tilting plate 30 by the sliding plate 50 and the slide case 2 is released while receiving the rotational force rotating in the (+ Z axis direction), the torsion spring for the tilting is automatically rotated upward. The slide case 2 is rotated together with the 40. At this time, since the roller 87 at the end of the tilt lever 81 is rolling along the lower surface of the tilting plate 30, the rotation movement of the tilt lever 81 can be made smoothly and smoothly.

The operation of the hinge module of this second embodiment will be described in more detail as follows.

As shown in FIGS. 16A and 18A, when the user slides the slide case 2 in one direction (Y-axis direction) of the main body case 1 in the closed state, the sliding plate 50 tilts. It moves along the guide rail member 35 of the plate (30). When one end of the slide case 2 and the sliding plate 50 is completely positioned on the tilting plate 30, the tilting plate 30 is hinged by the elastic force of the torsion spring 40 for tilting. It will rotate in the + Z axis direction. At this time, the tilting lever 81 of the auxiliary tilting unit 80 is rotated in the + Z-axis direction by the action of the compression spring 84 and the first and second cams (85, 86) for the tilting torsion spring (40) A rotating force is applied to the tilting plate 30 together with the slide case 2 to rotate. Accordingly, the slide case 2 is rotated in the + Z axis direction to be inclined at a predetermined angle with respect to the main body case 1.

At this time, the lower surface of the slide case 2 is supported by the stopper 70 installed at the end of the hinge shaft 20 as in the first embodiment described above, so that it is perpendicular to the surface of the slide case 2 during use. Even if a force is applied, the slide case 2 is easily rotated to vibrate or fall by resisting the force applied to the slide case 2 in the vertical direction.

When closing the portable terminal in the open state, if the rear end of the slide case 2 is pushed forward (in the Y-axis direction), the slide case 2 slides forward in the reverse order as before, and gradually- It is closed while rotating in the Z-axis direction. At this time, the tilt lever 81 of the auxiliary tilting unit 80 also returns to the initial state by rotating in the -Z axis direction by the force of the slide case 2 rotating in the -Z axis direction.

On the other hand, in the above-described second embodiment, the tilt lever 81 is in contact with the tilting plate 30 exerts a rotational force to rotate the tilting plate 30, otherwise the tilt lever 81 of the sliding plate 50 It may be to apply a rotational force for rotating the slide case 2 by applying a rotational force to the sliding plate 50 in contact with the lower surface to be relatively movable.

In addition, the auxiliary tilting unit 80 is configured together with the torsion spring 40 for tilting to double the rotational force by the torsion spring 40 for tilting, but otherwise does not constitute the torsion spring 40 for tilting. Without the auxiliary tilting unit 80 alone may be configured to rotate the slide case (2).
