Abstract: A dual-axis hinge is mounted between a cover and a base of a portable device and has a connecting bracket, an upper rotating bracket, a lower rotating bracket, an upper active gear, a lower active gear and a transmission gear assembly. The connecting bracket is mounted between the upper and lower rotating brackets. The upper and lower active gears are connected respectively to the upper and lower rotating brackets. The transmission gear assembly is connected between the upper and lower active gears to adjust a velocity ratio of the upper and lower active gears. Therefore, the cover and the base align with each other without a drop whether or not the upper and lower active gears are the same in teeth number or whether or not the included angles between the upper and lower rotating brackets with the connecting bracket are the same.

Abstract: A hinge is mounted between a cover and a body of an electronic device and has an eccentric sleeve and a resisting assembly abutting against each other. When the cover is pivoted, the eccentric sleeve is rotated as well. Because the eccentric sleeve has sectors with varied radiuses, the resisting assembly is compressed to conduct various resisting forces when the eccentric sleeve is rotated. When the cover is opened to a normal visual angle, the hinge provides a constant largest torque. Therefore, the cover is held at the normal visual angle even though the user hits the touch panel on the cover.

Abstract: The hinge is made with a metal injection molding process from an alloy having at least: from 4 to 32 wt % Mn, from 16 to 37 wt % Cr, and from Fe that fills up the rest of the percentage.

Abstract: A dual directional sliding hinge is mounted in a portable device with a cover, a first base and a second base and has a main panel, a first sliding unit, a second sliding unit. The main panel is attached to the cover. The first sliding unit is attached to the first base. The second sliding unit is attached to the second base. When the first and second sliding units slide at the closing position, the cover and the first and second bases are folded to have a smallest volume. Since the first and second sliding units have different sliding distances when sliding to different directions, the functioning units on the first and second bases are revealed alternatively. Therefore, the user can decide to use different functioning units as desired.
