The present invention relates to a slide opening and closing device for a mobile terminal, particularly in a slide opening and closing device having a structure that is automatically opened or closed when a force is initially applied to the slide body of the mobile terminal, by using the elastic force of the elastic member efficiently To reduce the number of and extend its life.

In recent years, as the penetration rate of portable wireless terminals increases, additional functions that are suitable for the user's taste are required for the portable terminals, as well as simple functions of wireless communication.

In response to these demands, portable terminals have evolved from a general bar type to a flip type, a flip up type, a folder type, and the like. To achieve.

This is because the folder type terminal has enough space for adopting the wide LCD module as the display device, and because the portable terminal is folded in half, the portability is superior to other terminals.

On the other hand, it is possible to have a display device having a wide LCD module of a similar size as a folder type terminal, and at the same time, a slide type terminal capable of contributing to the miniaturization of the terminal is known.

Such a slide type terminal has an additional advantage that the sub body corresponding to the cover is opened and closed by a sliding operation on the main body, and is opened and closed by a new operation while maintaining the advantages of the existing folder type terminal.

As such a slide type terminal, a sliding type portable wireless terminal is disclosed in Utility Model Registration Application No. 2003-0000136.

The terminal disclosed in this application is adapted to change the direction of the pressing force in an opening direction or a closing direction with respect to a guide means for guiding the slide body on the main body and a sliding position of the slide body between the slide body and the main body. It includes at least one elastic means is installed. And the elastic body can maintain the maximum open position or the maximum closed position without a separate stopper during the fully open or closed operation. As such elastic means, a torsion spring is adopted in which one end is fixed to the main body and the other end is fixed to the slide body.

By the way, since the torsion spring applies an elastic force to the slide body while the torsion spring rotates, the torsion spring is greatly tensioned and unfolded. For this reason, the torsion spring is operated largely while using less elastic force, and two torsion springs are arranged to compensate for the insufficient elastic force.

Therefore, the conventional slide opening and closing device, the assembly process is complicated by using two torsional springs, there is a problem that its life is shortened as the displacement of the torsional spring increases.

The present invention has been made to solve the above problems, an object of the present invention is to provide an elastic force of the elastic member in the slide opening and closing device having a structure that is automatically opened or closed when a force is applied to the slide body of the mobile terminal only initially. In order to effectively use it to reduce the number of elastic members and to extend the life.

The present invention for achieving the above object, the first plate; A second plate coupled to be slid in one direction from the first plate and having at least one inclined surface at an inflection point in which the inclined direction is reversed; Elastic means for generating an elastic force in a direction perpendicular to a direction in which the second plate moves; A binding member for fixing the elastic means on the first plate; And at least one slip member which receives the elastic force of the elastic means and transmits it to the inclined surface so that the second plate slides from the first plate.

Each of the inclined surfaces is formed at a position symmetrical with respect to the path along which the second plate moves, and the elastic means, the binding member, and the slip member are each paired.

In order to move the second plate in both directions from the reference position, the inclined surface,

A first inclined surface formed in one direction from which a second plate moves from a reference position and having a first inflection point in which the inclined direction is reversed; And

The second inclined surface is formed at a position symmetrical to the first inclined surface from the reference position, and may be configured as a second inclined surface having a second inflection point in which the inclined direction is reversed.

At least one guide rod is fixed to the second plate in a moving direction of the second plate, and the first plate is formed with a guide ball to which the guide rod is slidably coupled, and the first rod is coupled with the guide ball. One plate and the second plate are slidably coupled.

The elastic means is made of a torsion spring.

The first plate is coupled to a cover for preventing the elastic means from being separated.

The binding member has one or more links, one end of which is axially supported by the first plate and the other end of which is axially supported by the end of the elastic means, to support the elastic means to the first plate.

The slip member is formed of a roller that is axially supported by the link and rolls on an inclined surface of the elastic member.

At least one fixing groove is formed in each of the inclined surfaces to apply a predetermined stopping force to the roller.

Hereinafter, a preferred embodiment of a portable terminal to which the present invention is applied as described above will be described.
