The present invention relates to a rotating hinge device of a mobile terminal configured to move the hinge device in a straight or curved manner when the folder is rotated in the mobile terminal.

In general, the term “portable terminal” refers to a device that a user can carry and perform wireless communication with a counterpart. Such portable terminals are classified into various types in appearance. For example, portable terminals are classified into bar-type, flip-type, or folder-type terminals according to their appearance. The bar-type terminal means that the single housing is configured as a bar-type, the flip-type terminal means that the bar-type housing and the flip is rotatably coupled by the hinge device, the folder-type terminal is a single It is meant that the folder in the bar-shaped housing is rotatably connected by a hinge device and configured in a folding manner.

In addition, the portable terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. Rotation-type terminal means that the two housings are rotatably connected to open and close facing each other, the sliding-type terminal means that the two housings are opened and closed in the state facing the longitudinal movement. The variously classified portable terminals listed above will be readily understood by those of ordinary skill in the art.

In the above-mentioned various types of conventional portable terminals, the light and simple terminals have become mainstream, so that they are convenient to carry.

Although mobile communication services are gradually diversified and the multimedia devices of the portable terminals have been diversified, the portable terminals have not escaped the conventional foldable and sliding terminals. In addition, as the use of the portable terminal is becoming more common, the taste of the user is also diversified, but the form of the portable terminal does not satisfy various tastes of the users.

In order to solve the above disadvantages, a display rotatable mobile terminal has been developed.

The display rotatable mobile terminal rotates a display device of a folder to watch a video and a video so that a wide screen can be viewed.

As illustrated in FIG. 1, the display rotatable mobile terminal includes a main body housing 10 having a first hinge shaft A1 at one end, a folder 20, and a connecting member 30.

The rotation hinge device of the portable terminal of the present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those of ordinary skill in the art.

For example, the present invention can be applied to all portable terminals.

As described above, according to the rotary hinge device of the mobile terminal according to the present invention,

By configuring the hinge device to move linearly or curvedly when the folder is rotated in the mobile terminal, the folder can be placed close to each other in the main body housing to reduce unnecessary rotation space generated during the existing rotation, thereby miniaturizing the terminal. By constructing a dual hinge device for rotating the display device and the keypad of the terminal, it is possible to improve the use of the terminal by selectively rotating and using the display device and the keypad according to the use of the terminal, and also a straight or curved rotating hinge By applying the device to a swing type terminal, there is an effect that can be used for a variety of terminals.
