A sliding module employing a semi-automatic opening/closing of the portable terminal, is disclosed. A driving force is used to open and close the sliding-type portable terminal with the resilient force of an elastic means, by converting the direction of the driving force by means of sliders formed on a sliding guide and a sliding plate, respectively. Thus, a user can conveniently manipulate the sliding-type portable terminal.

A slide cover unit including: a substrate board formed with guide slots and slide rails, each guide slot being formed as a curved path with a ridge point; an upper cover having slide channels and formed with a transverse slot, the slide rails of the substrate board being slidably inlaid in the slide channels; and at least one resilient member having a fixed end fixed at an outer end of the slot and a free end equipped with a roller member. The roller member is slidably inlaid in the transverse slot and the guide slots. When the upper cover is moved, the roller member is moved along the transverse slot and guide slots to extend or compress the resilient member. When the roller member passes over the ridge point, by means of the resilient restoring force of the resilient member, the upper cover can further automatically move relative to the substrate board to complete opening/closing operation.

A cover assembly for covering a hinge (31) of a portable device includes a base (10) and a cover (20). The base (10) includes a fixing portion (11) protruding therefrom, a pair of slide protrusions (114) is formed on the fixing portion (11), and a latching slot (19) is defined in the base (10) adjacent the fixing portion (11). The cover (20) includes a pair of sliding slots (211) corresponding to the slide protrusions (114), and a hook (231) is formed on the cover (20) for engaging the latching slot (19).

A replaceable panel device (1) includes a panel (20) with a mounting portion (24), a locking subassembly (30), and a top cover (40) with a block (45). The mounting portion has at least one slideway (241), a recess (242), and two locating grooves (243). The locking subassembly is accommodated in the mounting portion of the panel. The locking subassembly has a button (31), an elastic rod (32), and a slider (33). The button has at least one rail (312), a hole (313) defined at top of the rail. The slider has at least one slot (331) and a rabbet (332). The slider is received in the recess. The rail is received through the slideway and the slot. The elastic rod is received through the hole. Ends of the elastic rod are located in the locating grooves. The rabbet engagingly receives the block of the top cover.

A latching assembly includes a removable panel (1), a knob (2), a sliding latch (3), and a base cover (5). The removable panel includes a mounting hole (12), a depression portion (13), and a plurality of catches (17). The knob includes a slanted protuberance (22), and the knob mates in the mounting hole. The sliding latch includes a head portion (32), a slanted portion (38), and a spring arm (34). The base cover includes a slot (51) matingly receiving the head portion, a plurality of catch slots (54) matingly receiving the catches, and a board (53). When the knob is pressed, the slanted protuberance engages with the slanted portion and the spring arm can move in the depression portion. As a result, the removable panel can be fixed on the base cover or released from the base cover easily.
