A sliding module with a scratch prevention device for a sliding-type portable terminal, including a body housing, a sliding housing, a main member provided in the body housing, a sliding member provided in the sliding housing and coupled such that the sliding member may slidingly move in the main body, a guide member provided on each of both ends of the main member, and a guide rail provided on each of both ends of the sliding member and slidingly movably coupled to the guide member so that the guide rail may be guided. The sliding module includes a scratch prevention portion provided on a part where the guide member and the guide rail contact each other, and at least one auxiliary scratch prevention portions provided crossing each other on a part where the guide member and the sliding housing contact each other.

Sliding module with scratch prevention device

A hinge apparatus for connecting a first housing and a second housing of a portable terminal is provided. The hinge apparatus includes a hinge housing and a damping member. The hinge housing is connected to the second housing and has an internal wall formed with one or more guide grooves extending in a circumferential direction of the hinge housing. The damping member is rotatably received in the hinge housing and rotates as the second housing rotates. The damping member has one or more frictional projections. In a first section corresponding to the position where the second housing is folded onto the first housing, the frictional projections contact the internal wall of the hinge housing. Similarly, in another section corresponding to the position where the rotation of the second housing is stopped after rotating away from the first housing, the frictional projections also contact the internal wall of the hinge housing. As a result, the hinge apparatus dampens impact produced at the moment the housings are folded or stopped after rotating away from each other, thereby improving the endurance and structural stability of the portable terminal.
