The present invention is a clamshell mobile communication terminal consisting of a main body including a cover that rotates around the hinge portion to be opened and closed and a support portion that limits the opening angle of the cover so that the cover is not opened more than a predetermined angle. The present invention relates to a foldable mobile communication terminal having an integrally provided in the housing a hinge buffer portion for preventing damage to the hinge portion and circuit elements due to the impact between the support and the support portion.

Due to the rapid development of the information and communication industry, the functions and types of mobile communication terminals such as mobile phones and PDAs are rapidly developing, and the number of users of mobile communication terminals is also rapidly increasing. In addition, mobile communication terminals include a bar type, a flip type, a sliding type, and a folding type. Among them, the size of the mobile communication terminal is small and light, making it easy to carry and making the LCD screen larger than other models. Therefore, the folder type mobile terminal having the advantage of displaying a lot of information on one screen has recently become the most popular item.

A conventional clamshell mobile communication terminal includes a main body including a keypad and a transmitting unit, a cover including a liquid crystal display and a receiving unit, and a hinge unit connecting the main body and the cover mechanically and electrically so that the main body and the cover can be rotated and opened. Consists of. At this time, the main body, by using the mobile communication terminal to maintain the opening angle between the main body and the cover around 150 degrees in accordance with the shape of the human face to improve the reception and transmission sensitivity, and to prevent the damage of the hinge portion due to the excessive opening of the cover A support is further provided to limit the opening angle of the.

However, in the conventional folding mobile communication terminal configured as described above, when the cover is opened, the cover and the support part collide by the force of opening the cover and the rotational inertia force of the cover, so that the cover, the support part, and the hinge part Since the impact force is applied to the back, there is a problem that the hinge and the circuit element may be damaged. Moreover, in recent years, as the liquid crystal screen of the mobile communication terminal is colored and its size is increased, the weight of the cover is gradually increased, and thus the impact force due to the opening of the cover is gradually increasing. Is becoming an even more important issue.

Therefore, in order to solve the above problems, the cover and the support portion is provided with a shock absorber, looking at the configuration as follows.

FIG. 1A is a side cross-sectional view of a folding mobile communication terminal having a conventional hinge buffer device in which the cover is opened to the maximum, and FIG. 2B is an enlarged view of part “A” in FIG. 2A showing a shape in which the cover and the damper touch each other. One part cross section.

As shown in Figure 1a and Figure 1b, the conventional folding type mobile communication terminal having a hinge buffer, the cover 20 and the cover 20 is rotated about the hinge 30 and the cover 20 is a predetermined angle or more In the clamshell mobile communication terminal, which is composed of a main body 10 including a support portion 13 that restricts excessive opening of the cover 20 so that the cover 20 is not opened, the support portion 13 is formed when the cover 20 is opened. A damper 11 formed of a material having elasticity and a damper groove 12 formed to seat the damper may be provided at a portion in contact with the cover 20 to serve as a shock absorbing material absorbing impact force.

The cover 20 is configured to be in contact with the damper 11 without being in contact with the support 13 even when the cover 20 is opened to the maximum. Therefore, the damper 11, by absorbing the impact force generated by the collision with the cover 20 when the cover 20 is opened to prevent damage to the mobile communication terminal due to the impact force, the cover is the maximum opening angle The excessive opening of the cover 20 is limited so as not to be opened above. In addition, since the cover 20 and the support part 13 are formed of a material having a predetermined rigidity or more, abnormal noise is generated when a collision occurs. However, the mobile communication terminal formed as described above has a soft buffer. Since it will collide with the damper made of material, no abnormal noise will be generated.

Figure 1c is a perspective view of a folding mobile communication terminal having a conventional hinge buffer to remove the cover to show the position and shape of the damper.

As shown in FIG. 1C, the support part 13 formed at the upper end of the main body has a damper groove 12 formed in a concave shape in a portion which comes into contact with the cover when the cover is opened, and a buffer role in the damper groove 12. A damper 11 is provided. Since the damper 11 is provided in a convex shape than the surface of the support part, when the cover is opened to the maximum, the cover contacts the damper 11 and is supported by the damper 11.

In order to provide a hinge buffer according to the above method, the damper 11 must be accurately positioned at a portion where the cover 20 and the support part 13 of the main body 10 come into contact with each other. It is not easy to find the exact location on which to rest. In addition, in order to absorb the impact force due to the impact between the cover 20 and the support portion 13 of the main body 10, the size of the damper 11 should be increased, and the support portion on which the damper 11 is seated ( 13) has a disadvantage in that there is a limit in increasing the size of the damper 11 in a narrow relationship.

In addition, the cost of the product is increased due to the increase in the number of parts due to the addition of the damper 11 and the addition of a manufacturing process for assembling the damper 11, and the damper 11 is removed from the main body 10. There is a concern that it may be dislodged, and when the damper 11 is dismounted from the main body 10, not only the impact force due to the collision with the cover 20 can be absorbed, but also the assembly hole 12a is external. Due to the exposure to the static electricity and the stability against the waterproof is also generated disadvantages.

The present invention has been made to solve the above-described problems, in the folding mobile communication terminal having a shock absorber to absorb the impact force generated by the impact between the cover and the body when the cover is opened, the stability of the shock absorption and In order to reduce the cost by increasing the efficiency and reducing the number of parts and assembly processes of the product, the object of the present invention is to provide a folding mobile communication terminal incorporating a support portion of the main body that collides with the cover and a hinge buffer absorbing impact force on the cover. have.
