The present invention relates to a hinge device and a personal portable terminal, and more particularly, to a hinge device capable of a sliding drive and a swing drive, and a personal portable terminal using the hinge device.

In general, a personal portable terminal may be classified into a flip method, a folder type, a swing-type, and a sliding-type according to an appearance or an operation method.

In the flip method, a display unit and a key input unit, such as a liquid crystal display (LCD), are generally formed on the same body, and the key input unit is protected by using a cover connected to the bottom by a hinge.

In the folder method, two folder parts can be opened and closed by hinges, and a main display unit and a key input unit are respectively formed on surfaces facing each other. The folder-type personal portable terminal can close two folders to protect the display unit and the key input unit, and can open a folder to receive a call or perform a desired function through key input.

In the swing-type personal portable terminal, two terminal bodies are disposed to face each other, and one terminal body is rotated 360 degrees while maintaining a state parallel to the other terminal body. Such a method is referred to as a swing-type personal portable terminal, and since the position of each terminal body can be freely designated, it has gained much popularity in recent years.

The slide-type mobile phone includes a sliding body overlapping up and down, and a sliding hinge device for connecting both bodies is interposed between the sliding bodies to interconnect the sliding bodies, and may assist sliding of each other. . Hinge devices of various structures have been disclosed in relation to the slide hinge device, but some of them use guide bars or shafts, and the sliding body can slide stably using the guide bars.

In addition, various portable personal terminals having various opening and closing methods using such a hinge device have been used, and recently, a sliding personal portable terminal and a swing portable personal terminal have been used. In this case, each mobile terminal using each method may have advantages and disadvantages.

In recent years, the sliding type personal portable terminal, which is widely used, has the advantage of being easily opened and closed by one hand, but has a disadvantage in that it is somewhat inconvenient to watch a video due to the fixed position of the display.

In addition, since the swing-type personal portable terminal can change the position of the display in various directions, it is possible to freely watch a video horizontally or vertically, but it is inconvenient to open and close the personal portable terminal with one hand. Therefore, a personal handheld terminal can be developed that can achieve only these advantages.

Accordingly, one object of the present invention for solving the above problems of the present invention is to provide a hinge device and a personal portable terminal capable of swing driving while sliding.

Another object of the present invention is to provide a hinge device and a personal portable device designed to rotate in both directions.

Therefore, the hinge device can slide and move the terminal body of the personal mobile terminal at the same time.

The conventional portable personal terminal can be invented a personal portable terminal that performs a swing drive at the same time as the slide drive. However, the personal portable terminal having such a structure has a thick thickness because the slide structure and the swing structure are designed separately. In addition, the personal handheld terminal having such a swing structure is designed to be able to rotate only in one direction, so that it feels somewhat inconvenient to rotate.

However, the hinge device according to the present invention, since the slide hinge portion and the rotary hinge portion are integrally connected to each other to reduce the mounting space, when mounted on a personal portable terminal can be reduced in thickness.

In addition, the subplate includes a rotation bar protruding downward, and the slide hinge portion is formed in a c-shape protruding upward. And, stoppers for blocking the movement path of the rotary bar, the stoppers may be located in the direction facing each other in the slide hinge.
