Abstract

An elastic unit in a portable terminal is provided to increase elastic force and durability by using a tension spring as a main power source, instead of torsion springs. An elastic unit in a portable terminal comprises the first shaft member(10), the second shaft member(20), the first connection member(30), the second connection member(40), and a tension spring(50). The first shaft member(10) and the second shaft member(20), arranged parallel to each other, generate tension in a direction crossing each other. Both ends of the first connection member(30) respectively are connected to one end of the first shaft member(10) and one end of the second shaft member(20). Also both ends of the second connection member(40) respectively are connected to the other ends of the first and second shaft members(10,20). The tension spring(50), of which both ends are arranged diagonally, generates elastic force to the first shaft member and the second shaft member in a crossing direction by pulling the first connection member and the second connection member.

The present invention relates to an elastic device for a mobile terminal, and more particularly, to an elastic device for generating an elastic force for automatically opening or closing a sub-body in a sliding type mobile terminal. It is for improving durability.

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

The terminal disclosed in this application is adapted to change the direction of the pressing force in the opening or closing direction with respect to the guide means for guiding the sub body on the main body and the predetermined sliding position of the sub body between the sub 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, one end of which is fixed to the main body and the other end of which is fixed to the subbody, is adopted.

This torsion spring is fixed to the main body and the other end is fixed to the sub body, the elasticity of the torsion spring is applied over the entire moving distance of the sub body, the torsion spring is greatly tensioned and stretched. Therefore, while the operation is large for the smooth operation of the torsion spring, a torsion spring with a small elastic force is used, and two torsion springs are installed to compensate for the insufficient elastic force.

However, the torsion spring has a problem in that the displacement width is large due to its characteristics, and thus, the normal function is lost or disconnected early due to the accumulation of fatigue due to the repeated operation.

The present invention has been made to solve the above problems, an object of the present invention is an elastic device for generating an elastic force to automatically open or close the sub body in a sliding type mobile terminal, the elastic force than the torsion spring This strong and durable tension spring is the main power source to improve the above problems.

The present invention for achieving the above object, the first shaft member and the second shaft member to increase in the side direction; A first connection member and a second connection member having both ends rotatably connected to the first shaft member and the second shaft member, respectively; And a first end connected to a first end side of the first shaft member or a region close to the first end side of the first connection member, and arranged in a diagonal direction from the first end side. A second end is connected to a region adjacent to the second end side of the second end side or the second connection member to tension the first shaft member and the second shaft member to generate an expansion force in a direction crossing each other. It provides an elastic device for a portable terminal comprising a spring.

Hereinafter, a preferred embodiment of the elastic device of the present invention will be described with the accompanying drawings.

1 is an exploded perspective view of an elastic device according to one embodiment of the present invention, FIG. 2 is a perspective view of a coupling state of the elastic device shown in FIG. 1, and FIG. 3 is a perspective view of the elastic device shown in FIG. 2.

In the elastic device shown in this figure, both ends of the first shaft member 10 and the second shaft member 20, and the first shaft member 10 and the second shaft member 20, which are raised in parallel directions, respectively. The first shaft member 10 and the second connecting member 30 and the second connecting member 40 and the first connecting member 30 and the second connecting member 40 are rotatably connected by pulling the first shaft member 10 and the second connecting member 40. The shaft member 20 is composed of a tension spring 50 for generating an elastic force in a direction crossing each other.

The first connecting member 30 is rotatably connected to one end of the first shaft member 10 and the second shaft member 20 by the first hinge shaft 12 and the second hinge shaft 14, respectively. The second connecting member 40 is rotatably connected to the other ends of the first shaft member 10 and the second shaft member 20 by the third hinge shaft 22 and the fourth hinge shaft 24, respectively. do.

One end of the tension spring 50 is connected to an area close to one end side of the first shaft member 10 of the first connection member 30, and the other end thereof is diagonal from the one end of the second connection member 40. It is connected to an area proximate the end of the second shaft member 20 which is placed on.

The first ring 52 and the second ring 54 are formed at both ends of the tension spring 50, and the first connecting member 30 is formed with a first groove 32 to which the first ring 52 is caught. The second connecting member 40 has a second groove 42 in which the second ring 54 is formed.

The elastic means having such a configuration is applied by replacing the torsion spring of the sliding type portable terminal. That is, one end of the first shaft member 10 is axially rotatable connected to the main body side of the portable terminal, and one end of the second shaft member 20 is axially rotatable connected to the sub body side.

Hereinafter, the operation of the elastic device having the configuration as described above.

Usually, both ends of the tension spring 50 pull the first groove 32 of the first connecting member 30 and the second groove 42 of the second connecting member 40 so that the first shaft member 10 and the first shaft member 10 are pulled. The biaxial member 20 generates the expansion force in the direction crossing each other, as shown by the arrow in FIG.

In this state, when the pressing force is applied to the left end of the first shaft member 10 and the right end of the second shaft member 20, the first shaft member 10 to the right as shown in FIG. Will move to the left. In this process, the first connecting member 30 and the second connecting member 40 are rotated and maintain the connection state between the first shaft member 10 and the second shaft member 20.

As the tension spring 50 expands as the first shaft member 10 and the second shaft member 20 move, the force is accumulated, and the distance between the first shaft member 10 and the second shaft member 20 is increased. Away.

In this state, when the pressing force applied to the left end of the first shaft member 10 and the right end of the second shaft member 20 is released, the tension spring 50 is connected to the first connecting member 30 and the second connecting member. As shown in FIG. 2, the first shaft member 10 moves back to the left side and the second shaft member 20 moves back to the right side by the pulling force 40.

As described above, the elastic device of the present invention has a higher elastic force and a smaller displacement width than the torsion spring used as the main power source, so that the elastic device of the present invention has excellent elastic force and long life.

The present invention has been described above by way of specific embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone can make a variety of variations.
