7A to 7C are diagrams for describing an operation of a display tilt hinge device of a bar type portable terminal according to an exemplary embodiment of the present invention.

First, in this embodiment, as shown in FIG. 7A, the state (close state) in which the sub body 5 of the portable terminal 1 is located in parallel with the main body 3 in a plane direction is set as an initial starting point.

Here, the main body 3 and the sub body 5 are in close contact with each other as a predetermined preload by the elastic force provided from the ballistic unit 51 of the elastic link 31.

At this time, the restricting pin 25 of the fixing plate 21 is located in the upper portion of the slot hole 46 of the rotating plate 41.

In this state, as shown in FIG. 7B, the user rotates the sub body 5 with respect to the main body 3 in a direction upward of a predetermined period of the entire rotation period.

Then, since the rotating plate 41 of the elastic link 31 is coupled to the sub body 5 through the first and second coupling bolts 91 and 92, the sub body 5 is centered around the fixing plate 21. ) Is rotated upwards in a certain section.

In this case, the rotating plate 41 may be rotated for a predetermined period while the first and second coupling bolts 91 and 92 are guided to the slot hole 4a and the slot groove 4b formed in the main body 3.

As the rotating plate 41 rotates as described above, the slide member 71 of the bullet unit 51 in this embodiment interferes with the restricting pin 25 of the fixing plate 21 with respect to the case member 61. It slides to the hinge engagement end side of the rotating plate 41.

That is, as the regulating pin 25 of the fixing plate 21 is made of a fixing cam, and the slide member 71 is made of a moving cam, in the process of rotating the rotating plate 41, the regulating pin 25 is formed. While pressing the cam protrusion 77 of the slide member 71, the slide member 71 can be slid to the hinge engaging end side of the rotary plate 41.

Then, the compressive elastic force of the elastic member 81 is transmitted to the rotating plate 41 through the slide member 71, and acts as a driving force to further rotate the rotating plate 41 in the upward direction.

In this state, when the user applies a slight rotational force with respect to the sub-body 5, the contact position of the regulating pin 25 with respect to the cam protrusion 77 is the highest point as the rotating plate 41 rotates more upwards. At this moment, the rotating plate 41 is rotated upward by the elastic restoring force of the elastic member 81 as shown in FIG. 7C.

That is, as the rotating plate 41 rotates by the elastic restoring force of the elastic member 81, the sub body 5 automatically rotates in the remaining sections of the entire rotating section, and is upwardly with respect to the main body 3. Tilt rotation by a certain angle.

At this time, the restricting pin 25 of the fixing plate 21 is located in the lower portion of the slot hole 46 of the rotating plate 41.

Subsequently, when the sub body 5 of the portable terminal 1 is closed in a state of being tilted with respect to the main body 3 in the present embodiment, the above operation is performed in the reverse order of the above procedure, and thus, the detailed description thereof will be omitted below. Let's do it.

As described above, according to the display tilt hinge device 100 of the bar type portable terminal according to the exemplary embodiment of the present invention, since the sub body 5 is tilted upward by a predetermined angle with respect to the main body 3, Through the display unit 7 on the front of the sub body 5, multimedia services such as viewing a photo or video file, watching a DMB, a game, or the Internet can be used more conveniently.

In addition, in the present embodiment, since the sub body 5 is tilted upward by a predetermined angle with respect to the main body 3, various character information is provided through the display unit 7 or a separate keypad unit (not shown). You can enter the text more conveniently.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
