The present invention relates to a sliding type opening and closing device of a portable terminal, and in particular, when a force is applied to the second body of the portable terminal only at an initial stage, the opening and closing are automatically and slide-opened, and the opening and closing device is opened and closed. It relates to a sliding type opening and closing device of a portable terminal to maintain a stopped state by.

Recently, as the penetration rate of portable wireless terminals increases, additional functions that are suitable for the user's taste are required for the portable terminal, 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 first 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 provides a guide means for guiding a second body on a first body, and a pressing force in an opening direction or a closing direction based on a predetermined sliding position of the second body between the second body and the first body. At least one elastic means is installed to change the direction. In addition, the second body can maintain the maximum open position or the maximum closed position without a separate stopper when the second body is fully opened or closed by the elastic means. As such elastic means, a torsion spring is adopted in which one end is fixed to the first body and the other end is fixed to the second body.

In this terminal, one end of the torsion spring is fixed to the first body and the other end is fixed to the second body, so that the torsion spring is elastically applied over the entire travel distance of the second body. You lose. For this reason, the torsion spring used a large elasticity while the operation was large, and two torsion springs were arranged to compensate for the insufficient elastic force.

However, in such a conventional switchgear, the torsion spring is greatly deformed, and thus there is a problem in that the torsion spring is easily aged due to fatigue due to repeated operation, and thus loses its normal function early.

In addition, two torsion springs are used, but the elastic force is not strong. Therefore, the opening and closing operation of the second body was not smooth, and there was a problem in that the second body flowed because the second body could not be firmly fixed in its closed and open state.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to automatically open or close in a sliding manner when a force is applied to the second body of the portable terminal only initially, and the closed state and the closed state. In order to generate a stopping force by the switchgear.

The present invention for achieving the above object, in a portable terminal having a first body, and a second body that is opened and closed by sliding in one direction from the first body,

A first plate coupled to the first body; A second plate coupled to the second body and slidably coupled to the first plate; A first block rotatably coupled to a first point of the first plate; A second block rotatably coupled to a second point of the second plate which does not coincide with the first point; A rod member configured to elastically connect between the first block and the second block; And an elastic member coupled to the rod member to generate an elastic force in the direction of opening the first block and the second block.

The second block is located in a direction in which the second plate is closed from the first block when the second plate is in a closed position on the basis of the inflection point of the movement path of the second plate, whereby the elastic force of the elastic member is increased in the second plate. To act in the closing direction,

When the second plate is in the open position, the second plate is positioned in the open direction so that the elastic force of the elastic member acts in the direction in which the second plate is closed.

The second block is installed at a position that shortens the movement distance when the second plate is opened than the movement distance when the second plate is closed.

The rod member may include an arm shaft fixed to one side of the first block or the second block and having a length shorter than a shortest distance between the first block and the second block; And a length fixed to the other side of the first block or the second block, shorter than a shortest distance between the first block and the second block, and sliding in the arm shaft during the opening and closing of the second plate. It includes a male shaft having a.

The elastic member is made of a compression spring.

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

1 is an exploded perspective view of a portable terminal according to an embodiment of the present invention.

A keypad is mounted on the surface of the first body constituting the portable terminal, and a main board for performing various functions is embedded therein. The second body is provided with a liquid crystal display, and the second body and the first body are electrically connected to each other through the flexible PC.

The first plate 100 is coupled to the first body, the second plate 110 is coupled to the second body and coupled to slide in one direction to the first plate 100.

To this end, the guide shaft 112 is fixed to the second plate 110, and the guide hole 102 to which the guide shaft 112 is slidably coupled to the first plate 100 is formed.

The first block 120 is rotatably coupled to the first point of the first plate 100 by the first hinge shaft 122.

The second block 130 is rotatably coupled to the second point of the second plate 110 where the first point and the movement path do not coincide by the second hinge shaft 132.

The second block 130 is located in the direction of closing from the first block 120 when the second plate 110 is in the closed position with respect to the inflection point of the movement path of the second plate 110, thereby providing an elastic member. The elastic force of the second plate 110 to act in the closing direction.

When the second plate 110 is in the open position, the second plate 110 is positioned in the open direction from the first block 120 so that the elastic force of the elastic member acts in the direction in which the second plate 110 is closed.

The second block 130 is installed at a position at which the moving distance at the time of opening the second plate 110 is shorter than the moving distance at the time of closing the second plate 110. This is to speed up the operation of opening the second body and the second plate 110.

The rod member elastically connects between the first block 120 and the second block 130.

The rod member is fixed to the first block 120 and has an arm shaft 140 having a length shorter than the shortest distance between the first block 120 and the second block 130 and the second block 130. The male shaft 142 is fixed and shorter than the shortest distance between the first block 120 and the second block 130 and has a length that slides inside the female shaft 140 in the opening and closing process of the second plate 110. Is made of. In addition, the male shaft 140 is installed on the second block 130 and the male shaft 142 is installed on the first block 120 to compensate for the connection strength.

The elastic member is coupled to the rod member to generate an elastic force in the direction of opening the first block 120 and the second block 130.

This elastic member is composed of two compression springs 150 fitted to the rod member.

On the other hand, the second plate 110 is provided with a separate stopper (not shown) for limiting the movement of the second plate 110 in a completely closed state and a fully open state in the first plate 100.

The operation of the present embodiment will be described below.

In the state in which the second body of the terminal is closed to the first body, as shown in FIG. At this time, the second plate 110 coupled to the second body is maintained in a closed state by the pushing force of the second block 130 which is subjected to the elastic force of the compression spring 150.

In this state, when the second body is pushed by hand to open the terminal, the second body and the second plate 110 slide together. At this time, the guide shaft 112 fixed to the second plate 110 moves along the guide hole 102 of the first plate 100, so that the second plate 110 can perform a good linear motion.

When the second plate 110 starts to open, the second plate 110 pushes the second block 130 so that the distance between the first block 120 and the second block 130 approaches. Accordingly, as the compression spring 150 is compressed to increase the elastic force, the compression spring 150 acts as a force to prevent the second plate 110 and the second body from being opened.

When the second plate 110 overcomes the disturbing force and continuously moves to pass the inflection point as shown in FIG. 3, the second block 130 opens the second plate 110 by the elasticity of the compression spring 150 again. Since it is pushed in the direction, the second plate 110 is automatically moved to an open position even when no force is applied to the second body and the second plate 110 from this time.

Since the distance from the closed position to the inflection point of the second plate 110 is shorter than the distance from the inflection point to the open position, the operation of opening the second plate 110 and the second body can be easily performed.

When the second body is fully open as shown in FIG. 4, the second plate 110 is maintained in the open state by the pushing force of the second block 130 that is subjected to the elastic force of the compression spring 150.

Since the keypad is exposed when the second body is opened, the user can use the unique function of the terminal.

On the other hand, to close the terminal while the second body is open, the user pushes the second body by hand in the opposite direction as in the open operation. The close operation of the second body is performed in the reverse order of the open operation.

When the second body reaches the closed position, the second plate 110 is maintained in a closed state by the pushing force of the second block 130 that is subjected to the elastic force of the compression spring 150.

 As described above, the portable terminal of the present invention uses a compression spring having a stronger elastic force than the torsion spring, and efficiently transmits the elastic force to the second plate, thereby smoothly opening and closing the second body. There is an effect that the state and the open state are firmly maintained.

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.
