The present invention relates to a slide hinge device and a personal portable terminal, and more particularly, the present invention relates to a slide hinge personal portable terminal and a slide hinge device mounted to the terminal.

In general, when the slide opening and closing, the existing slide mobile phone uses the torsion spring as its driving force, and the maximum distance of the slider movement is proportional to the size of the torsion spring, and the larger the distance is, the larger the torsion spring is. Only two round trips were possible. Hereinafter, the drawings will be described.

1 to 3 are views of a conventional slide mobile phone, Figure 1 is a perspective view showing a conventional slide mobile phone, Figure 2 is a diagram illustrating the configuration and operation of the slide opening and closing device of the conventional slide mobile phone.

In addition, one ends of the torsion springs 40 and 41 are respectively fixed to both sides of the main body 10, and the torsion springs 40 and 41 are moved semi-automatically.

FIG. 3 is an explanatory diagram for explaining the change according to the position of the torsion spring. FIG. 3 is a graph showing a spring operation on the left side and a torsional torque change on the right side.

Referring to Figure 3, the torsion spring is fixed in one end and moving the other end, i.e., the moving end from the point P1 to P2, the torque increases as the position of the moving end is displaced at the lowest point P1, so that the middle portion At maximum torque (load direction inflection point), and the torque decreases again to reach the uppermost point P2.

Therefore, in the semi-automatic slide mobile phone using the torsion spring as described above, when the slide unit 20 is opened with respect to the main body unit 10, the maximum torque (maximum compression point of the torsion spring) of the torsion springs 40 and 41 is maintained. It is manually moved by hand, and then automatically moved to the bottom or top end by the tension torque of the compressed torsion springs 40 and 41.

In this structure, the reciprocating motion is possible only at two points of the top and the bottom, and the reciprocating distance is limited by the width of the mobile phone. Therefore, the personal portable terminal to which the slide hinge device is applied has a limitation on the sliding driving direction because the mobile terminal slides only in one direction.

Accordingly, an object of the present invention for solving the above-described problems of the present invention is to provide a slide hinge device and a personal portable terminal that can be slid in a vertical direction.

In addition, another object of the present invention is to provide a slide hinge device and a personal portable terminal that can be used in combination with a semi-automatic sliding method and a manual sliding method.

Still another object of the present invention is to provide a slide hinge device and a personal portable terminal, which can provide a good slide feeling.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the slide hinge device includes a main hinge portion and a slide hinge portion.

The main hinge part is formed on the main plate for fixing to the terminal body, a guide groove formed in the main plate, and a side surface of the guide groove, protrudes into the guide groove, and a first guide rail formed on an upper portion of the guide groove. And second guide rails formed on both sides of the guide groove lower than the height of the first guide rail, and formed at a lower portion of the reference groove.
