Abstract: A pivotal hinge mechanism for a mobile computer may include a swivel seat, a support seat, and first and second pivot mounting parts. The swivel seat and the support seat cooperate to form a pivot joint that allows the swivel seat to swivel through 180 degrees with respect to the support seat. The first and second pivot mounting parts swivel about an axis that is perpendicular to the axis of the swivel seat's rotation.

Abstract: A fastener module for portable computers that is disposed on the host of a portable computer to fasten the LCD with the host, no matter whether the LCD is closed directly or after rotating 180 degrees; the fastener module has a pivotable eccentric hook rod biased in a normal horizontal position when not affected by magnetic effect, when the LCD closes on the host of the computer, both sides of the hook rod are affected by the magnetic effect of the magnetic component on the LCD; since the pivot of the hook rod is designed eccentrically, the magnetic moment generated by the magnetic effect for each side of the hook rod is different, so that the hook rod changes its position instantly from the normal horizontal state to a vertical state and hooks within the opening of the LCD to fasten the LCD onto the host of the portable computer.

Abstract: An improved pivotal hinge mechanism used for portable computer equipped with a stopper device which when portable computer and a docking station are joined together shall be actuated by the docking station to prevent the LCD of the portable computer from rotating in left and right direction, so that the collision happened between the docking station and the LCD of the portable computer due to rotation of the LCD relative to the computer mainframe shall be avoided; when the portable computer is disconnected from the docking station said stopper device shall immediately return to the normal position so that the LCD of the portable computer can rotate again in an angle of 0–180 degrees in left and right direction with respect to the computer mainframe.

Abstract: The present invention relates generally to a fastener module for portable computers that is disposed on the host of a portable computer to fasten the LCD with the host of the portable computer, no matter whether the LCD of the portable computer is closed directly or after rotating 180 degrees; the fastener module has a pivotable eccentric hook rod with a normal horizontal position under the effect of an elastic component when not being affected by magnetic effect, when the LCD closes on the host of the computer, both sides of the hook rod are affected by the magnetic effect of the magnetic component on the LCD; since the pivot of the hook rod is designed eccentrically, the magnetic moment generated by the magnetic effect for each side of the hook rod is different, so that the hook rod changes it position instantly from normal horizontal state to vertical state and hooks in the opening of the LCD to fasten the LCD onto the host of the portable computer.

Abstract: A pivotal hinge mechanism for mobile computer having high assembly precision comprising a swivel seat, a support seat, a first pivot mounting part, a second pivot mounting part and a positioning plate, wherein the swivel seat and the support seat are installed together to form a pivot joint, and said swivel seat has a first stopper shoulder which enables an angular movement range of ?1 and said support seat has a second stopper shoulder which enables an angular movement range of ?2; by way of ?1+?2 being limited equal to 180 degrees, to enable said swivel seat have an angle rotation within a limited range of 0˜180° when said swivel seat with respect to said support seat making a rotation; in addition, the pivotal hinge mechanism for mobile computer has touch sense function which enables the user to make sure that the swivel seat has reached the specific angular position by touch sense or sound signal.

Abstract: An improved pivotal hinge mechanism used for portable computer equipped with a stopper device which when portable computer and a docking station are joined together shall be actuated by the docking station to prevent the LCD of the portable computer from rotating in left and right direction, so that the collision happened between the docking station and the LCD of the portable computer due to rotation of the LCD relative to the computer mainframe shall be avoided; when the portable computer is disconnected from the docking station said stopper device shall immediately return to the normal position so that the LCD of the portable computer can rotate again in an angle of 0-180 degrees in left and right direction with respect to the computer mainframe.
