The present invention relates to a swing-type mobile communication terminal structure, in which two or more rotating bodies are coupled and rotated to provide various types of display parts and input parts, thereby implementing various types of display parts, and according to the position of the display part and the input parts. The present invention relates to a structure of a mobile communication terminal that can utilize various multimedia functions in an optimized form by providing a terminal structure.

In general, a mobile communication terminal is a mobile communication device for a user in a location separated from each other to communicate through a base station. Recently, with the rapid development of the electronic communication industry, mobile communication terminals have been added with various designs and the addition of new functions, and the functions of the mobile communication terminals have been gradually expanded to enable the transmission of text messages and various information as well as internet access. It is also possible to transmit video calls or image information.

The spread of such mobile communication terminals has been widely generalized, and the trend of mobile communication terminals having various opening and closing methods of mobile communication terminals is rapidly spreading. For example, a mobile terminal such as a mobile communication terminal or a PDA is formed by combining a main body with a keypad and a cover body with a liquid crystal screen so as to be openable and close, and a folder according to the opening and closing structure of the cover body for the main body. It may be classified into a mold, a slide mold, a swing mold, and the like.

The folding portable terminal has a structure in which the cover body is opened and closed while being tilted within a predetermined angle range with respect to the main body centering on the hinge means formed between the main body and the cover body. In the case of the slide portable terminal, the main body The cover body is opened and closed while sliding within a predetermined length range with respect to the main body by sliding means respectively formed on the cover body and the cover body. In the case of a swing-type portable terminal, the cover body is at a predetermined angle with respect to the main body. When rotating, the cover body is rotated 180 degrees by the rotation opening and closing device provided between the main body and the cover body, and the cover body is opened to the main body.

In addition, as the wireless Internet service is commercialized, various contents (music and movies) have been downloaded and utilized, and the demands of consumers related to mobile communication terminals have been diversified. The trend of the large LCD screen emphasizing the multimedia function and the mobile communication terminal capable of converting into various forms is rapidly spreading.

Therefore, since a larger size of the LCD screen is required to display a larger amount of information at a time, the size of the LCD screen can be increased compared to the existing terminals, and terminals that can be easily converted into various forms are preferred.

1 is a perspective view showing a conventional foldable mobile communication terminal, Figure 2 is a perspective view showing a conventional slide type mobile communication terminal.

As shown in FIG. 1, in order to view the LCD screen 21 and the keypad 11, the folder-type mobile communication terminal needs to open the folder 20 to the front of the main body 10, and the LCD screen 21 is vertically formed. Since it is formed in the horizontal form, the keypad 11 input is not easy. In addition, when the folder 20 is opened, the entire keypad 11 is exposed, and when the folder 20 is closed, the entire keypad 11 cannot be used.

As shown in FIG. 2, the slide-type mobile communication terminal needs to raise the slider 20 'with respect to the main body 10' in order to view the keypad 11 '. Although the LCD screen 21 'is used in a horizontal form while the slider 20' is lowered, the use of the keypad 11 'is not easy. In addition, even when the slider 20 'is lowered, some input units can be used, but they are limited.

Therefore, in the foldable type and the slide type, which are the main types of the current terminal, the use of the terminal is limited to the opening and closing of the folder 20 and the movement of the slider 20 ', and thus various types of LCD screens cannot be utilized in one terminal. For this reason, in order to utilize various multimedia functions and wide forms, the user must take inconvenience and cause a user error by such inconvenience.
