The present invention relates to a slide type mobile phone, and more particularly, to a mobile phone in which a subbody slides with respect to the main body using a link and a compression spring.

Typically, portable wireless communication terminals (hereinafter referred to as mobile phones) can be classified into bar type, flip type, and folder type mobile phones according to their appearance.

The bar-type mobile phone is a type in which a data input / output means and a handset are mounted in a main housing, and a keypad, which is a data input means, is exposed at all times, which may cause a malfunction. The problem is that miniaturization is limited.

The flip-type mobile phone is composed of a main body, a flip module and a hinge module for connecting the main body and a flip. The main body is provided with a data input / output means and a handset, and the flip is a keypad for the data input means. Coverage can prevent malfunction, but the flip-type mobile phone also has a limitation in miniaturization due to the distance between the transmitter and the receiver.

The clamshell-type mobile phone is composed of a main body, a folder, and a hinge module for rotatably connecting the main body and the folder. The folder-type mobile phone is opened and closed by rotating the folder. Malfunctions can be prevented, and in the call mode, the folder can be opened to sufficiently secure the distance between the transmitter and the receiver, which is advantageous in miniaturization.

The flip or clamshell mobile phone is a hinge module for rotatably coupling a flip or a folder to the main body, when the flip or the folder rotates from the main body by a predetermined angle, the force is provided in an open direction even if no more force is applied. In the case is provided with a force in close contact with the body.

On the other hand, as the design of the mobile phone is diversified, a slide type mobile phone that opens and closes a keypad installed on the main body is gradually commercialized by sliding the sub body on the main body.

However, the above pre-registration proposals use the two torsion springs so that when the subbody is brought up / down with respect to the main body, when the subbody reaches the point where it opens or closes by 1/2 position on the main body, Since the direction of the pressing force is changed drastically, the subbody slides sharply toward the fully open or fully closed position on the main body, so there is a problem that not only noise is generated but also a poor working feeling. This is because the elasticity is strong when both ends of the torsion springs are retracted and expanded.

In addition, the above pre-registration proposals reduce the repulsion force of the torsion spring during long-term use, and thus weaken the force during opening and closing of the sub-body, causing the sub-body to descend during the call, resulting in a call drop. In addition, there is a problem that the battery power is discharged when the sub-body is opened when you carry it in your pocket.

On the other hand, an example of a device for driving the body of the slide-type mobile phone to solve the above problems has been disclosed in Korean Utility Model Registration No. 363295, which uses only two compression springs to slide the sub-body with respect to the main body It is.

However, the design of the Republic of Korea Utility Model Registration No. 363295, when the sub-body up / down with respect to the main body, the slide ring is not smooth or damaged as the hook ring formed at the end of the compression spring is bent or damaged, durability is reduced There is a problem.
