Abstract:
1. A portable communication device comprising: a first housing; a second housing, facing the first housing when the device is in a folded state; and a hinge assembly rotatably engaging the first housing with the second housing, the hinge assembly including: wherein the movement of the head triggers rotation of the rotating hinge unit, thereby automatically rotating the first sliding housing and the second housing around a hinge axis of the hinge assembly to open the device to an unfolded state, wherein the sliding cam includes a guide inclined surface that supports the corresponding movement of the head, the sliding cam sliding in a direction perpendicular to the hinge axis, the head moving in a direction parallel to the hinge axis, and further comprises, an elastic presser coupled to the rotating hinge unit, wherein rotationally transitioning the first housing and second housing to a closed configuration moves the elastic presser such that the head and the sliding cam are returned to an original position, wherein the elastic presser includes: a pressing member for contacting a mover coupled to the head, the pressing member moving the mover by elastic force; and a coil spring for providing the elastic force to the pressing member, and further comprise, an engagement releaser coupled to the mover, and rotating when the mover moves and contacts the engagement releaser; a support housing coupled to the mover, partially enclosing the engagement releaser and providing physical support for the rotation of the engagement releaser and the movement of the mover; and a hinge module having a hinge shaft coupled to the engagement releaser, so that when the engagement releaser rotates, the hinge shaft is released to an engaged state of rotation, the hinge shaft automatically rotating the rotating hinge unit by elastic force provided by a hinge shaft elastic member coupled to the hinge shaft.
