When the cover 200 of the portable terminal is completely closed, the sliding bar 400 is positioned at the lowest point of the guide bar 300.

Subsequently, when the cover 200 is lifted upward, the torsion spring 500 is deformed and elastic energy begins to accumulate. As a result, the torsion spring 500 gradually has a property to be restored to the initial state and provides a force to the sliding bar 400 in the direction in which the cover 200 is closed. However, when the force in the same direction is continuously applied to the cover 200 while overcoming the elastic restoring force of the torsion spring 500, it finally reaches a transition point.

At the transition point, the cover 200 is opened about halfway, and the sliding bar 400 is positioned at an intermediate point of the guide bar 300. At this time, the accumulation value of the elastic energy in the torsion spring 500 is the highest, but no force is applied to the cover 200 in the open or closed direction.

Subsequently, once the transition point passes, the torsion spring 500 rebounds while releasing the accumulated elastic energy to provide a force in the opening direction of the cover 200. As a result, the cover 200 is completely opened in the main body 100, and the sliding bar 400 is located immediately at the top of the guide bar 300. At this time, the cover 200 is maintained in the open state unless the force applied from the outside becomes the state in which the accumulated elastic energy is released to the torsion spring 500.

The preferred embodiment of the present invention has been described above. The present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. For example, unlike the above embodiment, the guide bar and the sliding bar may be installed in the cover and the main body of the mobile terminal, respectively. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the simple slide cover opening and closing device for a portable terminal according to the present invention and a portable terminal using the same reduce the thickness of the portable terminal because the slide hinge module is composed of a bar-shaped part rather than a plate. It can be effective.

In addition, the present invention can reduce the cost of production by minimizing the cost of the parts for the same reason as described above.

In addition, although the present invention is composed of the bar-shaped parts as described above, the stable sliding opening and closing operation of the cover is guaranteed.
