Description

Swing hinge for mobile phone {SWING HINGE FOR USE IN RADIO TELEPHONE}

The present invention relates to a swing hinge mounted on a portable device such as a mobile phone.

Portable devices such as mobile phones have a keypad with a plurality of buttons and a liquid crystal display for providing a screen. When a small liquid crystal display is used, a keypad and a liquid crystal display are provided together in one case unit. However, when a larger liquid crystal display is used, it is not appropriate that the keypad and the liquid crystal display are provided together in one case unit as described above. This is because the area of the mobile phone becomes wider and the mobile becomes inconvenient. Recently, a keypad and a liquid crystal display are respectively provided in order to use a larger liquid crystal display, and a portable telephone having two case units that can be superimposed with each other is mainly used. In addition, as a variety of services such as video viewing are available through a mobile phone, a mobile phone in which a unit having a liquid crystal display is rotated so that the liquid crystal display can be arranged horizontally as well as vertically is used. To this end, a swing hinge is required to connect a unit provided with a liquid crystal display. 1 shows a foldable cellular phone configured to fold and unfold two units. (A) of FIG. 1 is a closed state, (b) is an open state. In Fig. 1B, the liquid crystal display 13a is arranged vertically. In this state, the state where the liquid crystal display 13a is rotated and arranged horizontally is shown in FIG. Conventionally, the rotation axis (rotation axis of the swing hinge) of the liquid crystal display 13a is fixed, so that the liquid crystal display 13a is positioned relatively as shown in FIG. As a result, the center of gravity is located above, and the liquid crystal display 13a is easy to move backwards as indicated by the arrow, which is inconvenient to use.

Now, the operation of this embodiment will be described in detail with reference to Figs. 6A to 6M.

First, referring to FIG. 6A, the display unit 16 is longitudinally disposed, and the first moving member 40 is positioned at the first position 3121 of the first track 312 and the second moving member ( 50 is located at the third position 3131 of the second trajectory 313. In addition, the contact member 74 of the rotating part 70, that is, the rotating shaft of the rotating part 70 is located above the passage hole 311. The first elastic member 80 and the second elastic member 90 provide an elastic force in a direction that prevents the connecting plate 72 of the rotating unit 70 from rotating in the clockwise direction. Therefore, the display unit 16 is to maintain the vertical arrangement in a stable manner. When the external force in the clockwise direction is applied to the display unit 16 in this state, the first moving member 40 and the second moving member 50 are elastic members along the first track 312 and the second track 313, respectively. The elastic force of (80, 90) is overcome and moved and positioned at the first intermediate position 3123 and the second intermediate position 3133, respectively, as shown in FIG. 6H. Until this time, the position of the contact member 74 is not changed. Further rotation in this state, as shown in Figure 6i, the first moving member 40 passes through the first intermediate position 3123 of the first track 312, the second moving member 50 is Passes through the second intermediate position 3133 of the second trajectory 313. In this state, the elastic members 80 and 90 apply a force to rotate the connecting plate 72 in the clockwise direction. Thereafter, the first moving member 40 moves down the right side in the first track 312, and the second moving member 50 moves down the left side in the second track 313. At this time, the rotating member of the contact member 74, that is, the moving part 70 moves downward along the passage hole 311. Thereafter, the first moving member 40 is located at the second position 3122 of the first track 312 and the second moving member 50 is located at the fourth position 3132 of the second track 313. The contact member 74 is positioned below the passage hole 311, so that the display unit 16 is disposed horizontally downward. This state is shown in Fig. 6m. The state shown by the broken line shows the state when the center axis of the display unit 16 is rotated without moving down.
