Typically, portable terminals refer to portable devices such as HHP, CT-2, PCS phones and the like. Such a portable device performs a communication function while performing wireless communication with a base station.

At present, such portable terminals are being developed in accordance with the trend of miniaturization and light weight of electronic components, and a bar type and a flip type coexist. In such bar type and flip type, flip type mobile phones having excellent sound sensitivity are becoming more common. The reason why the flip type mobile phone is generalized is that the flip cover installed in the main body protects a plurality of buttons to prevent malfunction of the buttons, and collects the sounds by acting as a negative reflector during a call. Moreover, flip type mobile phones will become more common because they are advantageous for miniaturization.

Such a conventional flip-type mobile phone is composed of a flip cover, a body and a hinge means for mechanically connecting the flip cover and the main body, and the phone is opened or closed depending on whether the flip cover is opened or closed. It is designed to be an automatic transition mode or call waiting mode. Currently, mobile phones are becoming smaller, but mobile phones are limited in size to secure the distance between the user's ear and the mouth. That is, in the case of a portable terminal, the distance between the talker (part where the microphone device is installed) and the receiver (part of the earpiece including the speaker) should be 14 cm or more. Therefore, the trend is trying to solve the distance by installing a microphone or a speaker on the flip cover.

In the flip type mobile phone, the type of the flip cover rotating shaft installed at the bottom of the main body is called a "flip down type portable radiotelephone", and the rotating shaft of the flip cover is mounted at the top of the main body (on both sides of the LCD module). The type installed in the structure is called a "flip down type portable radiotelephone". That is, a hinge device for opening and closing the flip down type mobile phone by rotating the flip cover is installed at the bottom of the main body, and a hinge device for opening and closing the flip up type mobile phone is installed on the upper side of the main body.

The conventional hinge device has a structure in which two hinge modules are mounted symmetrically. According to this structure, the hinge device is opened and closed while rotating from the bottom to the top of the hinge axis. In addition, it was a configuration having a mechanism capable of electrically connecting the speaker installed in the flip cover to the printed circuit board of the main body. At this time, the two wires drawn from the speaker were directed toward the main body through the hinge knuckle via the neck of each flip cover.

However, the hinge device of the present application is configured such that the opening and closing angle of the flip cover is about 180 °, and there is a risk that an excessive force is applied to the neck of the flip cover when an excessive force is applied to the flip cover during the flip cover opening and closing operation. . Furthermore, if the flip cover is opened up to about 180 °, in consideration of the communication distance between the earpiece and the microphone of the main body, there is a problem that it is inconvenient to use from the user's point of view.

In general, when using a mobile phone, the user tends to talk with the earpiece close to the ear and the mouth of the microphone, and a mobile phone that is opened and closed by a conventional hinge device has been a cause of inconvenience for the user.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention to provide a flip cover stop device of a flip-up type mobile phone easy to use from the user's point of view.
