The present invention relates to a rotary hinge device of a portable electronic device and a dual hinge device having the same, which are configured to rotate in a straight line by a hinge device having a gear when the folder is rotated in the portable electronic device.

In general, the term “portable electronic device” refers to a device that a user can carry and wirelessly communicate with a counterpart. Such portable electronic devices are classified into various types in appearance. For example, portable electronic devices 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 electronic device may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. The rotation-type terminal means that the two housings are rotatably connected and opened in a facing state facing each other, and the sliding-type terminal means that the two housings are opened and closed in a state facing each other by longitudinal movement. The variously classified portable electronic devices listed above will be readily understood by those of ordinary skill in the art.

In the above-mentioned various types of conventional portable electronic devices, a light and simple terminal has become mainstream for convenience of carrying, and there is a disadvantage in that it is particularly convenient only during a voice or video call with the other party.

As mobile communication services are gradually diversified and multimedia devices have become portable devices, portable electronic devices have not escaped the form of conventional folding and sliding terminals. In addition, as the use of portable electronic devices is becoming more common, the tastes of users are also diversified, but the shape of the portable electronic devices does not satisfy various tastes of users.

In order to solve the above disadvantages, a display rotating portable electronic device has been developed.

The display rotating portable electronic device rotates the display device of a folder to watch a video and a video so that the display can be viewed on a wide screen.

As shown in FIG. 1, the display rotating portable electronic device includes a main body housing 10 having a first hinge shaft A1 at one end, a folder 20, and a connection member 30. The key housing 11 and the microphone 12 are mounted to the main body housing 10. The connection member 30 connects the body housing 10 and the folder 20, and the folder 20 in a direction closer to or away from the first hinge axis A1 in the body housing 10. Makes it rotatable. In addition, the connecting member 30 is provided with the second hinge axis, and the folder 20 is rotatably connected to face the connecting member 30, and the folder 20 is connected to a display device. A display unit (LCD) 21 and a speaker 22 are provided.

However, in the conventional display rotating portable electronic device, as shown in FIG. 1, when the folder is opened about the first hinge axis, the corner end of the rectangular display device is rotatable when the display device of the folder is rotated. Since the rotation space D1 is required between and the folder, and the display rotation axis of the folder is located at the center of the folder, the above rotation space is unnecessarily generated during folder rotation. In addition, as the display device increases, the rotation space D1 also increases together, increasing the size of the terminal and acting as a deterrent to miniaturization.

Also. As the size of the display device increases, the rotation axis accordingly is located at the upper end of the main body, and in this state, the folder may fall when the folder is placed on the floor.

Accordingly, the present invention is configured to rotate the folder having a hinge axis in the eccentric position in the portable electronic device to reciprocate in a straight line by a gear during rotation, thereby positioning the folder close to each other in the main body housing when rotating the existing. The present invention provides a rotating hinge device for a portable electronic device and a dual hinge device having the same, which can reduce the unnecessary rotation space generated and can improve the use of the terminal.
