Problems solved by technology

[0007] However, the above-mentioned prior art hinge device is limited in achieving a reduction in thickness because it requires a housing for accommodating the spring and the guide bar.
Therefore, portable wireless terminals using a hinge device are limited in terms of slimming
[0008] Also, due to the compression of the spring as the rod is moved to penetrate further into the housing, friction noise can be generated between the housing and the spring

Abstract

The present invention discloses a hinge device for a cellular phone, which has no device housing and thus, can achieve a greater slimness of the cellular phone and reduce the generation of a noise during a sliding operation of a slide body included in the cellular phone. The hinge device includes a first push rod connected to a main body of the cellular phone and having a pin and a pin hole, and a second push rod connected to a slide body of the cellular phone and having a pin and a pin hole. The pin of the first push rod is penetrated through the pin hole of the second push rod, and the pin of the second push rod is penetrated through the pin hole of the first push rod. A spring is provided around each pin.

Description

technical field [0001] The present invention relates to a hinge device for a cellular phone, and more particularly to a hinge device for a cellular phone that does not require a separate device housing, thereby allowing for a greater degree of slimming of the cellular phone , and reduce the generation of noise during the sliding operation of the sliding body included in the cellular phone. Background technique [0002] The portable wireless terminal has been developed from a bar type terminal to a flip type terminal, an upward flip type terminal, and the like. Recently, folder-type terminals and slide-type terminals have become the main styles of portable wireless terminals. Among these various terminals, a slide-type terminal has an open operation structure in which a sliding body having a display window slides on a main body having a keyboard so as to move away from or toward the main body. With this configuration, in addition to providing a slide type terminal having a ...
