The present invention relates to a sliding device of a slide type mobile phone, and more particularly, a coil winding part is formed with a certain distance deviation in a straight line of fixing pins to which a coil spring is fixed, so that a uniform tension is always applied and the structure is simplified. It relates to a sliding device of a slide-type mobile phone to reduce the manufacturing cost.

In general, a portable wireless terminal (commonly referred to as a 'mobile phone' or 'mobile phone', hereinafter referred to as a mobile phone) is a wireless communication device that allows a user to carry a call while carrying it in his hand or carrying it on his body.

In addition, the mobile phone has a variety of functions and designs are released to meet the needs of the user, the flip type (flip type) provided with a cover for protecting the button from the bar type (bar type) is exposed to the outside of the first button and The mobile phone has been developed into a folder type, and recently, a slide type mobile phone in which a cover equipped with a display unit slides is used in a main body equipped with a keypad.

In addition, the slide-type mobile phone is provided with a slide device so that the cover slides in the main body, the slide device from the manual to the user manually slides the cover guided through the guide rail provided on the main body to the gear teeth of the rack and pinion The semi-automatic type using the spring which has the cost saving effect due to the structure and the simple structure is mainly used recently.

Here, the sliding device using the spring, with reference to the registered Korean Utility Model No. 353355 (name: slide type mobile phone module), Figure 1 is an exploded perspective view of a conventional slide type mobile phone module, Figures 2a to c As a state diagram of a conventional slide-type mobile phone module, referring to this, it is installed between the main body 10 on which the keypad 11 is mounted and the cover 20 on which the display unit 21 is mounted. It consists of a slide module 30 for opening and closing the sliding movement with respect to the main body 10.

The slide module 30 is mounted to the main body 10 by a screw coupled to the through hole 44, the guide plate 41 is formed on both sides of the lower plate 40 and the screw coupled to the through hole 55 Mounted on the cover 20 by the upper plate 50 is formed with a coupling groove 51 corresponding to the guide rail 41 to be movable relative to the lower plate 40, one end is fixed pin 42 It is fixed to the lower plate 40 and the other end is fixed to the upper plate 50 by the fixing pin 52 and has a compression coil spring 60 having a predetermined length, to the restoring force of the compression coil spring 60 By moving the upper plate 50 relative to the lower plate 40 to open and close the cover 50 with respect to the main body 10.

At this time, at least one end of each of the compression coil springs 60 is formed adjacent to the fixing pins 42 and 52 fixed to the lower plate 40 and the upper plate 50, respectively. 50) is provided with guide pins 43 (53, 54) to serve as a guide to prevent the twisting of the compression coil spring (60) and to not be slid to one side during sliding movement.
