A cover positioning structure of a dual-usage portable computer is disclosed, which comprises a base, at least one slide block sliding on the base, at least one elastic slice imposing a pressure to the at least one slide block, and a rotary member rotated relative to the base. When rotated, a positioning protrusion of the rotary member is correspondingly positioned to a positioning recess of the at least one slide block. Therefore, the structure aforesaid not only achieves the positioning purpose of being damage-free, but also is cost-effective in having a minimum of elements and manufacture processes.

Cover positioning structure of a dual-usage portable computer

A common lock used in a dual-usage portable computer formed of a base member and a display is disclosed to include a left-side hook and a right-side hook respectively pivoted to the base member on the inside, and an elongated operating frame bar axially slidably mounted inside the base member of the portable computer and coupled between the left-side hook and the right-side hook for operation by the user to bias the left-side hook and the right-side hook by means of a lever action and to further force the left-side hook and the right-side hook out of a respective through hole at the base member into engagement with a respective retaining block at the display to lock the display to the base member.

Common lock for dual-usage portable computer

A display auto-locking structure includes a base member, an open frame pivoted to the base member and rotatable relative to the base member, a display pivotally mounted within the open frame and rotatable relative to the open frame, and a spring-supported cam rod mounted inside the open frame for locking the display to the open frame after the display has been set in one of two reversed positions within the open frame and for enabling the display to be rotated relative to the open frame after the open frame has been rotated relative to the base frame to a predetermined angle.

Display auto-locking structure

A common pivot arrangement mounted on a base member with first and second locating holes is disclosed to include a hinge unit having first through holes corresponding to the second locating holes of the base member and second through holes, and a rotary device, which has a mount with through holes corresponding to the first locating holes and a wheel with mounting holes corresponding to the second through holes. For use in a notebook computer, the first through holes of the hinge unit are respectively fastened to the second locating holes of the base member with screws. For use in a tablet PC and the notebook computer, the second through holes of the hinge unit are respectively fastened to the mounting holes of the wheel with screws, and then the through holes of the mount are respectively fastened to the first locating holes of the base member with screws.

Common pivot arrangement of portable computer

A swivel display inclining structure used in a dual-use portable computer is disclosed to include a touch panel pivoted to the top surface of the base member of the portable computer, two spring members for supporting the touch panel in an inclined position relative to the base member of the portable computer to support the swivel display of the portable computer in an inclined open position, two latches slidably mounted on the base member of the portable computer for locking the touch panel to the base member of the portable computer in a received position, and an operating bar for pressing by the user to disengage the latches from the touch panel for enabling the touch panel to be forced outwards from the received position to the inclined position by the spring members for supporting the swivel display in the inclined open position.

Swivel display inclining structure

A mobile computer tilting arrangement is disclosed to include a casing, the casing comprising at least two recessed locating holes respectively disposed in at least two corners of the back side thereof, and two plugs selectively detachably press-fitted into two of the at least two recessed locating holes for supporting the casing on a flat surface in a sloping position, each plug comprising a center through hole, and a pin insertable into the center through hole to radially expand the respective plug into friction engagement with one recessed locating hole of the casing into which the respective plug is press-fitted.

Mobile computer tilting arrangement

A coupling structure coupled between a base and a display panel is disclosed to include a pivot structure fixedly fastened to the base, a rotary platform pivotally coupled to the pivot structure for allowing rotation of the rotary platform on the pivot structure, a gear set, which includes a center gear fixedly fastened to the pivot structure and a left-side gear and a right-side gear pivotally mounted inside the rotary platform and meshed with the center gear at two sides respectively, the left-side and right-side gears each having the same number of teeth and a raised portion, and a hinge member, which is received inside the rotary platform and fixedly fastened to the display panel and has two elongated blind holes respectively coupled to the raised portions of the left-side gear and right-side gear.

Coupling structure

Portable notebook/tablet computer

A rotatable display mounting arrangement is disclosed to include a base having a first pivot structure, an open frame, the open frame having a second pivot structure pivotally coupled to the first pivot structure of the base and a second pivoting means symmetrically disposed at top and bottom frame bars thereof, and a display horizontally rotatably mounted within the open frame, the display having a first pivoting means symmetrically disposed at the top and bottom sides and respectively pivoted to the second pivoting means of the open frame, the first pivoting means having wire holes for the passing of the electric circuit wire of an antenna embedded in the top frame bar of the open frame and the electric circuit wire of the base to the display.

Rotatable display mounting arrangement
