Hinge device for portable wireless terminal

摘要

Disclosed is a hinge device of a portable wireless terminal. The portable wireless terminal includes a first housing (11), a second housing (12) rotatably coupled to the first housing (11) in such a manner that the second housing (12) moves away from the first housing (11) or approaches the first housing (11) according to a rotational movement thereof, a first hinge axis (A1) extending parallel to an upper surface of the first housing (11), and a second hinge axis (A2) extending perpendicular to the upper surface of the first housing (11) and providing a rotational center for the first hinge axis (A1). The first and second hinge axes (A1,A2) act as rotational axes of the second housing (12) when the second housing (12) rotates with respect to the first housing (11). The hinge device has a first hinge module (100,300) including a first hinge base (101,301,302) fixedly coupled to the first housing (11), and a second hinge base (102,303) rotatably coupled to the first hinge base (101,301,302) in opposition to the first hinge base so as to be rotated about the second hinge axis (A2), and a second hinge module (200) fixed to the second housing (12) and connecting the second housing to the second hinge base (103,303) in order to allow the second housing to rotate about the first hinge axis (A1).
