Description

PERSONAL PORTABLE DEVICE HAVING A DUAL-SHAFT HINGE STRUCTURE}

The present invention relates to a clamshell terminal. More specifically, the present invention relates to a personal portable terminal for freely adjusting the movement between the folders constituting the body of the terminal.

In general, a folder type terminal includes a main folder and a subfolder connected by one hinge. The main folder mainly includes a battery, a communication module circuit, and a key input unit, and the sub folder may include a liquid crystal display (LCD) module, a camera module, and the like. In addition, the subfolder can be opened only at a predetermined angle of about 130 to 150 ° with respect to the main folder. In general, the foldable terminal can move back and forth only within a certain angle range, which is used only for a call.

Of course, some terminals use double hinges having two axes facing different directions. The terminal having a double hinge includes a first hinge that rotates while keeping the horizontal level between the main folder and the sub folder, and includes a second hinge that rotates at an angle between the main folder and the sub folder, and an angle between the sub folder and the main folder. You can adjust variously. However, even if you have a double hinge can move only a certain angle in the direction of the call, there may be a problem that the thickness of the hinge increases significantly.

One object of the present invention is to provide a personal portable terminal that can be rotated on the basis of a separate axis of each of the two folders, the movement between the folders in various ways depending on the purpose of use of the terminal.

Another object of the present invention is to provide a personal portable terminal which can be fixed or released by the user arbitrarily, even if the folder is rotated about a different axis, and can be rotated regularly while maintaining a constant relationship.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the personal portable terminal pivots about a hinge body, a first folder pivoting about a first axis of the hinge body and a second axis of the hinge body. It includes a second folder. It also includes a gear member capable of interlocking the first and second folders and a key member capable of selectively controlling the transmission of rotation between the first and second folders by the gear portion. Thus, according to the operation of the key member, the first and second folders may be opened while simultaneously moving relative to the hinge body, or alternatively, only the first folder may be moved while keeping the second folder fixed to the hinge body. The user can operate the key member so that the first and second folders move together or move separately. By using this property, the angle between the folders can be variously adjusted according to the use purpose.

Specifically, the first folder and the second folder are rotatably mounted on the first axis and the second axis of the hinge body, respectively. In the present specification, an axis is a virtual line serving as the center of rotation of the first and second folders, but may use a shaft connected as one, but may also be defined by a separate shaft, and a part that is structurally protruding and a receiving portion thereof. It can also be defined by.

The gear portion also includes a first gear that is integrally interlocked with the first folder on the first axis and a second gear that can freely rotate relative to the second folder on the second axis. Further, the key member may physically bind or separate the second folder and the second gear. Therefore, when the second folder and the second gear are physically bound, the first folder and the second folder move together while maintaining a constant relationship with each other. However, when the second folder and the second gear are physically separated, the first and second gears are physically separated. Even if the gears are engaged with each other, since the first and second folders are separated from each other, only the first folder can move as in the conventional folding terminal.

According to the recent trend, the function of the personal mobile terminal is changing in various ways such as taking a picture or video, watching a television or a video in addition to a simple call function, and maintaining the angles between folders according to each function. The personal portable terminal according to the present invention can change the cause of movement between folders by using a key member, and can vary the angle between the folders according to the function of using the same.
