The present invention relates to a structure for reducing the impact when the cover is opened in a communication terminal in which the cover is foldable to the main body, and more particularly, by installing the cover buffer means inside the cover hinge part to open the cover. The present invention relates to a cover buffer structure of a folding type communication terminal capable of preventing a terminal from being damaged by the buffer means when the cover is opened and closed while maximizing a buffering effect.

A folding communication terminal in a communication terminal (or mobile communication terminal) such as a mobile phone or a personal digital assistant (PDA) terminal, while the cover is pivotally hinged to the main body, allows the cover to be rotated and opened. In this case, a large LCD screen is provided so that the LCD screen inside the cover can be checked when the cover is pivotally opened.

In the folding communication terminal as described above, since the opening and closing of the cover occurs frequently, the opening and closing operation of the cover should be minimized so that the cover opening and closing operation may proceed smoothly, thereby extending the life of the terminal. In addition, the user can maintain stability and give stability to the user.

In such a folding communication terminal, various conventional examples for minimizing an impact when opening a cover are shown in the accompanying drawings, FIGS. 1 and 2.

First, the cover buffer structure disclosed in FIG. 1 has a structure in which a separate buffer member 30 made of a rubber material or the like is attached to one side of the terminal body 10 in a direction opposite to the cover 20.

This shock absorbing structure is such that the shock is absorbed by the cushioning force of the shock absorbing member 30 when the cover 20 is in contact with the shock absorbing member 30.

However, in the conventional shock absorbing structure, since the cover 20 slides against the shock absorbing member 30, it is difficult to maximize the shock absorbing effect, and the cover 20 is scratched by a scratch phenomenon caused by friction. There are disadvantages such as this occurring. In addition, when the terminal is used for a long time, foreign matters such as dust penetrate between the main body 10 and the cover 20 and are also attached to the buffer member 30 so that the scratches become more severe.

In addition, the shock absorbing member 30 is prominent on the outside of the terminal, there is a disadvantage that adversely affects the appearance of the terminal.

On the other hand, although not shown in the drawing, unlike the above-described conventional example having a separate buffer member 30, the portion where the cover 20 and the main body 30 abuts as thick as the buffer member 30 There is an example. This example may have a slight improvement in design in comparison with the above example, but the impact absorption is low, and when the cover 20 is frequently opened and closed for a long time, the appearance of the cover may be reduced by friction between the cushioning member and the cover. There is a disadvantage that can not escape from the problem of damage to the appearance of the terminal due to scratches.

And, the cover buffer structure disclosed in Figure 2, when the buffer member 32 is positioned outside the main body 10 or the cover 20, when the cover 20 is opened and abuts against the buffer member 32, The shock is absorbed by the cushioning force of the buffer member 32.

This shock absorbing structure, unlike the above-described examples in which the cover 20 slides against the shock absorbing member 30, has a shock absorbing effect as compared to the above examples because the cover 20 directly contacts the shock absorbing member 32. Although it can be improved, the impact amount is transmitted directly to the main body 10 and the cover 20 to receive an intensive impact load, which may cause damage to the main body 10 or the surface of the case 20, the buffer member 32 is Because it is completely exposed to the outside of the terminal there is a disadvantage that is very poor in aesthetic appearance of the terminal.

The present invention was developed to solve the above problems, an object of the present invention, by installing the buffer means inside the hinge portion of the main body and the cover, while maximizing the buffer effect without damaging the aesthetics of the terminal, opening and closing the cover It is to prevent the phenomenon that the terminal is damaged by the buffer means.

In order to achieve the above object, in the present invention, in the communication terminal that the cover is foldable through the hinge portion in the main body, an arc-shaped buffering projection is formed in any one of the hinge portion of the main body and the cover is On the other side, at the end of the opening of the cover with respect to the main body is formed with an opposing protrusion that abuts on the opposing surface of the buffering projection, wherein at least one of the opposing surface of the buffering projection and the opposing projection A cover buffer structure of a folded communication terminal is provided, wherein a shock absorbing member is provided to absorb a shock when the shock absorbing protrusion and the opposing protrusion touch each other.

According to the present invention, when the cover is opened, the shock absorbing ability can be maximized and the shock absorbing effect can be maximized because the entire face of the shock absorbing protrusion or the opposing face of the opposing protrusion directly contacts the entire face of the opposing face of the buffer member. .

In addition, since the buffer structure (means) is formed inside the hinge portion of the main body and the cover, there is no fear of damaging the aesthetics of the terminal, and there is no possibility of scratching the appearance of the main body or the cover during the buffering action.
