4A and 4B show assembled cross sections according to A-A and B-B of FIG. 3, respectively.

First, in FIGS. 4A and 4B, the movable body 40 described above is slidably coupled to the rail 30 through the guide parts 32 and 41, and is the rotating body 50. The upper rotating body 60 and the pinion gear 70 have their insertion shaft portions 62 and 71 rotatably passed through the engaging holes 42 of the movable body 40 and are coupled by screws 73. .

The bushings 80 and 81 described above are interposed between the upper rotating body 60 and the moving body 40, and the pinion gear 70 and the moving body 40, respectively, and the upper rotating body 60 and the pinion gear ( 70) guides the rotation smoothly.

Is done.

5A and 5B, the operation of the present invention made as described above will be described. Since detailed operations of the present invention, such as the coupling structure, the use of a horizontal wide screen, the anti-twist structure of the FPC has already been fully described, below, the principle that the upper body 20 slides and swings with respect to the lower body 10. Only the operation process will be described in detail. 5A and 5B, respectively, two drawings are shown. The upper view is a view from above, and the lower view is a view from above of the upper view.

5A and 5B, in order to clearly understand the operation process of the present invention, the lower main body 10 and the upper main body 20 are not illustrated, and thus the rail 30 and the lower rail 30 are fixed. The main body 10 remains fixed without sliding or rotating. In addition, since the upper main body 20 is integrated with the rotating body 50, that is, the upper rotating body 60 and the pinion gear 70, the movement of the upper rotating body 60 and the pinion gear 70 is immediately performed. The main body 20 is moved.

First, FIG. 5A shows a state in which the upper main body 20 is closed with respect to the lower main body 10 and coincides with each other. At this time, since the movable body 40 remains completely moved downward of the rail 30, and the upper rotating body 60 is kept in the correct position, the upper main body 20 with respect to the lower main body 10. It will be closed in a perfect match.

In such a state, when the upper body 20 is pushed up, the upper rotor 60 is pushed up accordingly, and the movable body 40 also moves the rail 30 by the movement of the upper rotor 60. It slides up. When the pinion gear portion 50a of the pinion gear 70 meets the rack gear portion 31 of the rail 30 while the movable body 40 and the upper rotary body 60 slide up, the pinion gear portion 50a is engaged with the rack gear portion 31, and the pinion gear portion 50a of the pinion gear 70 has a gear tooth of the rack gear portion 31 by a force for sliding up the upper body 20. Rotation of the pinion gear 70 takes place because it is continuously engaged with i). When the pinion gear 70 rotates, the upper rotor 60 coupled thereto is integrally rotated to start the rotation of the upper body 20. Therefore, the upper rotating body 60 and the upper main body 20 slide upward of the main body 10 simultaneously with the rotation (swing).

In this manner, as shown in FIG. 5B, when the movable body 40 moves up to the end of the rail 30, the pinion gear 70, the upper rotating body 60, and the upper main body 20 are moved. The rotation is completed at an angle of 90 degrees.

As such, when the upper main body 20 is rotated at an angle of 90 degrees, the LCD screen 21 provided therein is horizontally disposed so that various multimedia functions can be performed smoothly and conveniently through the wide screen of the horizontal type. Will be.

As described above, the upper body 20 is rotated at an angle of 90 degrees, and if it is to be moved back to the original state, the upper body 20 is rotated in the opposite direction as before. Then, the upper rotor 60 and the pinion gear 70 are integrally rotated in the opposite direction by the rotation of the upper main body 20, so that the pinion gear 70 is again the rack gear part 31 of the rail 30. As the upper body 20 is rotated while moving downward, the upper main body 20 also rotates in the original direction and slides down. Since the pinion gear portion 50a of the pinion gear 70 is out of the rack gear portion 31 in this slide down process, the upper body 20 is completed in the initial state (return) to complete the lower body. Side by side coincides with (10), and continues to slide down in that state until the upper main body 20 is completely coincident with the lower main body 10 to stop.

In the above, the configuration of a multi-foldable mobile communication terminal according to the present invention has been described in detail as a specific embodiment shown in the accompanying drawings, but this is only one preferred embodiment, and the protection scope of the present invention is limited thereto. no. Therefore, the embodiments of the present invention as described above can be variously modified and equivalent other embodiments by those of ordinary skill in the art within the technical spirit of the present invention, such modifications and equivalent other embodiments are It goes without saying that it belongs to the appended claims of the invention.

As described above, in the mobile communication terminal according to the present invention, the upper body is automatically swinged at an angle of 90 degrees in accordance with an operation of sliding up / down the upper body with respect to the lower body, thereby utilizing a horizontal LCD screen. It is very convenient to use.

In addition, the connection between the main PC of the lower body and the sub PC of the upper body is via a middle connector, and a hole is formed in the center of the rotating body which rotates the upper body, thereby connecting the FPC through the hole. By having the above, it is possible to smoothly perform the above-described slide and swing operation without the twist phenomenon of the FPC.
