The present invention relates to a hinge device and a portable terminal using the same. More particularly, the present invention relates to a hinge device and a portable terminal using the same.

As a function such as a camera, a camcorder, or the like is mounted on a mobile phone, a PDA, or a portable computer, a hinge structure for viewing a wide screen by rotating a folder and attaching it to a main body is widely used. In particular, as DMB (Digital Multimedia Broadcasting) is spreading, the necessity of attaching a folder to a main body for a long time is increasing. In addition, due to the addition of multimedia functions, a key capable of performing various and complex functions is required, which causes a design burden of mounting a separate key.

 1 is a perspective view of a portable terminal having a conventional swivel hinge, and FIG. 2 is a perspective view illustrating a state in which a folder is attached to a main body by rotating a folder in the terminal of FIG. 1.

The portable terminal having the conventional swivel hinge shown in FIG. 1 is coupled by a folder 1 having an inner screen 2, a folder 1 and a swivel hinge 6, and a plurality of keys 4 It includes the main body (3) provided. The folder 1 is coupled to the main body 3 so as to be openable and closed by the rotary hinge 5 formed at the upper end of the main body 3. In addition, a swivel hinge 6 protruding in the vertical direction is coupled to the folder 1 at one side of the rotary hinge 5, and the folder 1 is rotatable 180 ° by the swivel hinge 6. The folder 1 is mounted on the main body 3 in a state where the inner screen 2 is exposed to the outside by the 180 ° rotation of the folder 1.

At this time, since the folder 1 rotates symmetrically about the center line X of the main body 3, the folder 1 is completely superimposed on the main body 3, as shown in FIG. Therefore, the conventional portable terminal illustrated in FIGS. 1 and 2 has a problem in that a key formed in the main body 3 cannot be used and a separate key must be designed.

In order to solve the problem that the key cannot be used by attaching such a folder to the main body, a conventional portable terminal having an eccentric swivel hinge having a configuration in which a part of the key is exposed when the folder is rotated is illustrated in FIGS. 3 to 4. It is.

3 and 4 are a perspective view showing a perspective view of a portable terminal having a conventional swivel hinge and a state in which a folder is attached to the main body.

In the portable terminal having the swivel hinge shown in FIGS. 3 to 4, the folder 1 is asymmetrically rotated by the swivel hinge 6 formed so as to be deflected with respect to the central axis X of the main body 3. 3) is mounted on. Therefore, as shown in FIG. 4, a part of the key 4 provided in the main body 3 is exposed to the outside.

However, the portable terminal having such an eccentric swivel hinge, as shown in Figure 4, when the inner screen 2 is exposed to the outside when the form of the terminal is asymmetrical is not good appearance. In addition, since the volume increases by an asymmetric part, there is a problem in that it is inconvenient to use and carry the terminal when it is not necessary to use the key 4.

The present invention is derived to solve the problems of the prior art as described above,

An object of the present invention is to provide a hinge device and a portable terminal using the same that can be used by exposing the inner screen to the outside as well as sliding the folder as needed.

The folder has an inner screen 71 and the main body 60 has a plurality of keys 61.

14 is a perspective view showing a state in which the folder is rotated by the second hinge shaft 31.

As shown in FIG. 14, the second hinge shaft 31 formed at one side of the first hinge shaft 11 becomes a rotation center of the folder and allows the folder to rotate 180 °. Since the second hinge shaft 31 is located on the main body 60 and the center line X of the folder, the folder rotates in left and right symmetry.

15 is a perspective view illustrating a state in which the folder 70 is mounted on the main body 60 while the inner screen 71 is exposed to the outside.

Since the second hinge shaft 31, which is the rotation center of the folder 70, is positioned on the center line X of the folder 70 and the main body 60, the folder 70 rotates symmetrically to the main body. Fully nested at 60. Therefore, the edge of the folder 70 and the edge of the main body 60 coincide, whereby the key 61 provided in the main body 60 is covered by the folder 70.

Therefore, in the present invention, when the inner screen 71 is used for a long time such as watching a DMB broadcast, as shown in FIG. 15, the folder 70 can be used in a state completely overlapped with the main body 60. In addition to reducing the volume of the terminal there is an advantage that can be more easily carried.

FIG. 16 is a perspective view illustrating a state in which the key 61 of the main body 60 is exposed by sliding the folder 70 in the extending direction of the first hinge shaft 11.

The folder 70 is connected to the first hinge shaft 11 by the second hinge shaft 31 and the guide member 53, and the guide member 53 is a lower side surface of the folder 70. Since the folder 70 is slidably inserted into the guide groove (not shown) formed in the guide groove, the folder 70 is slidable in the extending direction of the first hinge shaft 11 while being connected to the first hinge shaft 11. Therefore, when using the key 61 attached to the main body 60 while watching the inner screen 71, the folder 61 may be slid upward to expose the key 61.

According to the present invention, since the key 61 formed in the main body 60 can be used by sliding the folder 70 as necessary, it is not necessary to add a separate function key to the terminal. The key 61 to which the folder 70 is exposed by sliding may be designed to have a separate function when the inner screen 71 is exposed to the outside.

Although various embodiments of the present invention have been described above, these embodiments are only examples of implementing the technical idea of the present invention, and any modified or modified examples are included within the scope of the present invention as long as the technical idea of the present invention is implemented. It should not be taken any further to be interpreted as.

The present invention can achieve the following effects by the above configuration.

According to the present invention, the inner screen can be exposed to the outside, and the key provided in the main body can be used by sliding the folder 70 as necessary, thereby providing a hinge device that is convenient to carry and excellent in appearance. .
