An exemplary embodiment of the present invention relates to a sliding cover opening and closing device for a mobile terminal, and more particularly, to an elastic link module for sliding the cover up and down from the body of the mobile terminal.

In general, in order to use services such as broadcasting and communication wirelessly while moving in a place that is not a fixed location, mobile terminals such as mobile phones, PDAs, notebook computers, and DMB phones are frequently used.

The portable terminal is one of the essential necessities that are indispensable in order to enjoy the convenience of life according to the development of the information industry, and the mobile phone is widely distributed to elementary, middle and high school students and the elderly.

In the portable terminal as described above, various methods are applied to open and close the cover, and the mobile terminal can be divided into a hinge method, a slide method, and a swing method.

In particular, the portable terminal for opening and closing the cover by the slide method is one of the most applied in recent years because of various advantages such as easy to use, less trouble, and have a stylish design.

The basic structure of the portable terminal for opening and closing the cover by the slide method is configured to slide the cover provided with the display portion up and down from the main body provided with the keypad.

Sliding up and down of the cover as described above is implemented through a cover opening and closing device, such a cover opening and closing device is manufactured as a variety of structures around each manufacturer.

The sliding cover opening and closing device of the mobile terminal according to the prior art is a guide member fixed to the main body, a movable member fixed to the cover and slidably assembled to the guide member, and both ends of the movable member and the guide member are rotatable. It is basically provided with an elastic unit to be coupled.

The elastic unit is, for example, a pair of rotary plates facing each other and rotatably coupled to the movable member and the guide member, a support plate for slidably supporting the rotary plate between these rotary plates, and interposed between each rotary plate and the support plate. Compression coil spring is made.

Therefore, in the prior art, when the user applies a force to the cover until the movable member is slid for a certain period while the cover of the mobile terminal is opened or closed, each rotary plate rotates and slides through the support plate to compress the compression coil spring. Done.

Thus, the elastic restoring force of the compression coil spring is provided to the moving member and the guide member through the respective rotating plate, so that the sliding movement of the moving member according to the opening and closing of the cover is automatically performed by the elastic restoring force of the compression coil spring in the remaining sections. Is done.

By the way, the elastic unit of the prior art is formed as a structure for compressing or tensioning the compression coil spring while each rotating plate is slid in the longitudinal direction of the supporting plate with the support plate therebetween, the distance between the rotation center of each rotating plate (operation length, sto Since the change in lock length) is limited by the support plate, it is difficult to develop a mobile terminal having a relatively long length or a narrow width.

In addition, in the above-described prior art, since the rotating plate is supported by the supporting plate and rotates and slides, the supporting plate may flow up and down by the rotating plate, and thus, there is a possibility that accurate and smooth opening and closing operation of the cover may not be performed.

Further, in the conventional technology, since the rotating plate is in contact with the movable member and the guide member, damage to the movable member and the guide member, such as scratches, occurs when the cover is opened and closed, and the cover is opened and closed such as causing noise and frictional resistance. There is also a problem that causes a problem in operation.

It provides an elastic force to the moving member and the fixing member.

And when the moving member passes a certain section, the remaining section is automatically sliding the movement of the moving member according to the opening and closing of the cover while each case is rotated by the elastic restoring force of the first and second coil.

By the way, in the prior art as described above, since the first and second coil parts of the integrated spring are embedded in each case and connected to each other through the connection part, the overall structure is complicated, and the manufacturing cost is increased. This breakage involves a problem that the inherent operation of the elastic unit becomes impossible.

In addition, in the prior art, as each case is rotatably coupled to the moving member and the guide member, each case may flow up and down when the cover is opened and closed, so as to accurately and smoothly open and close the cover as in the prior art. There is a problem that the operation is not made.

In addition, in the prior art, since the case of each case is made in contact with the movable member and the guide member, the movable member and the guide member may be damaged, such as scratches, as in the prior art, causing noise and frictional resistance.

In this case, the elastic members 70 are maintained in a compressed state between the main support 31 of the body 30 and each rotator 50.

That is, the elastic members 70 are compressed to the maximum as each rotator 50 rotates, and the elastic restoring force is transferred to the first sliding member 110 and the second sliding member 120 through each rotator 50. Will be exercised.

Therefore, the second sliding member 120 is automatically moved upward by the elastic restoring force of the elastic members 70 even if the user no longer applies a force to the cover 5.

As the second sliding member 120 moves upward as described above, as shown in FIGS. 14 and 15, the first sliding member 110 is the other end (lower) end of the second sliding member 120. The cover 5 of the portable terminal 1 is completely opened while being positioned at the portion.

In this process, each rotator 50 is rotated by the elastic restoring force of the elastic members 70 to return to the original position, the elastic members 70 is restored (tensified) to the original state.

The case member 10 is rotated in one direction to maintain a beveled state on the other side with respect to the moving direction of the cover 5.

Here, each rotator 50 is seated on both sides of the inclined surface 12 of the case member 10 in its original position, the inclined surface 12 serves as a stopper, thereby maintaining a predetermined initial angle.

In the present embodiment, when the cover 5 is closed from the main body 3 of the portable terminal 1 in the open state, the operation is performed in the reverse order to the above process, and thus the detailed description thereof will be omitted.

In the series of processes as described above, the slide cover opening and closing device 200 for a mobile terminal according to an exemplary embodiment of the present invention, as described above, the body 30 is firmly supported on the case member 10. Since the rotator 50 is rotated, the body 30 may be prevented from being twisted or moved by the elastic force of the elastic members 70.

In addition, in this embodiment, since the boss 61 of each rotator 50 is rotatably coupled to the boss groove 43 while being guided to the guide groove 42 of the side support 41, the rotation of each rotator 50. At the time, the boss 61 can be prevented from axial movement or the rotator 50 is separated.
