The present invention relates to a portable wireless terminal, and more particularly, to a portable wireless terminal and a hinge device thereof.

In general, the portable wireless terminal is classified into a flip type, a folder type, a slide type, a swing type, and a bar type mobile phone according to its appearance.

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 sliding personal portable terminal is a personal portable terminal in which two sliding parts are disposed to overlap each other, and the display unit and the key input unit face the same direction on the sliding part, respectively. In general, the sliding type personal portable terminal may expose the display unit or the key input unit hidden on the rear side by sliding the front sliding part relatively.

Lastly, the bar-type terminal is configured in such a manner that a keypad, which is a data input means, a display device, which is a data output means, a talker, and a receiver module, is mounted in one housing. There is an advantage to this.

However, the conventional bar-type mobile phone is equipped with all the functions in one body housing, so if the receiver is close to the user's ear when making a call, the microphone moves away from the user's mouth and the call sensitivity decreases. If the mouth is close to the receiver is far away from the user's ear there is a problem that the hydration sensitivity is lowered.

Accordingly, an object of the present invention for solving the above-described problems of the present invention is to provide a personal handheld terminal and its articulated hinge device capable of bringing the microphone close to the mouth even when the receiver of the terminal body is in close contact with the ear. .

Another object of the present invention is to provide a personal handheld terminal and a hinge device that can be easily refracted and easily designed with respect to the other terminal body since the rotary knob is mounted.

It is yet another object of the present invention to provide a click hinge device and a personal handheld terminal which are temporarily fixed to the initial position and the rotated position.

It is still another object of the present invention to provide a semi-automatic hinge device and a personal portable device that automatically rotate by elastic force after a certain distance.

According to a preferred embodiment of the present invention for achieving the above objects of the present invention, the articulated hinge device has an upper fixing portion, a lower fixing portion and a hinge knob. Here, the articulated hinge device can be applied to a bar type personal portable terminal, and the bar type personal portable terminal generally uses one terminal body, but the present invention includes an upper terminal body and a lower terminal body. However, in another embodiment of the present invention, it can be applied to a personal portable terminal of other opening and closing method according to the intention of the designer.

The upper fixing part is mounted on the bottom of the upper terminal body and includes an upper hinge projecting downward on the front side. Therefore, the upper fixing part is fixed to the upper terminal body to connect with the lower fixing part. The lower fixing part is mounted on an upper portion of the lower terminal body, and includes a lower hinge plate protruding upward on the front side to be rotatably coupled to the upper hinge and a lower support plate extending toward the rear surface.

In addition, the personal mobile terminal may further include a function hinge as an internal hinge portion. The functional hinge is mounted on the upper fixture and can be designed as a semi-automatic hinge or as a click hinge. The hinge of the semi-automatic type means that the hinge rotates automatically when a certain distance is rotated, and the click hinge means a hinge in which the initial position and the later position are temporarily fixed. Then, the rotary knob is formed on the side of the functional hinge and forms a protrusion protruding to the rear of the upper and lower terminal body. The rotary knob has an elongated portion formed from the axis of rotation and is spaced between the upper and lower fixing portions when the rotary knob is rotated by the long portion. At this time, the rotation angle of the rotary knob is characterized in that greater than the angle between the upper fixing portion and the lower fixing portion. Here, since the rotating angle of the rotary knob is formed larger than the angle formed between the upper fixing portion and the lower fixing portion, it is easy to design a semi-automatic hinge and a click hinge on the inner hinge portion.

Conventionally, the bar-type hinge device is equipped with all the functions in one main body housing, so if the receiver is close to the user's ear, the microphone is far from the user's mouth and the call sensitivity is reduced. If it is close to the receiver is far from the user's ear there is a problem that the hydration sensitivity is lowered.

The articulated hinge device according to the present invention rotates the rotary knob to bend the upper fixing part and the lower fixing part, thereby inclined by a predetermined angle between the respective terminal bodies by the articulating hinge device. Therefore, the personal handheld terminal inclined by a certain angle between the body of each terminal, even when the receiver is in close contact with the ear can close the microphone of the lower terminal body close to the mouth can maintain a good feeling of communication.

The articulated hinge device of the present invention can be applied to a personal portable terminal, and the structural advantages and economic benefits applied to the button device can be equally applied to the personal portable terminal. In the present specification, a personal portable device (Personal Portable Device) refers to a portable electric and electronic device such as a PDA (Personal Digital Assistant), a smart phone, a handheld PC, a mobile phone, an MP3 player, and the like.
