Abstract: A hinge module includes a joint assembly, a first pivot, and a second pivot. The joint assembly includes a first joint washer, a second joint washer separate from and coplanar with the first joint washer, an interlock member having two elongated limiting holes, and two pins. The first joint washer has a first pivot hole and a first pin hole. The second joint washer has a second pivot hole and a second pin hole. The pins are respectively inserted into the first and second pin holes and movably pass through the limiting holes. The first and second pivots respectively pass through the first and second pivot holes. When the first joint washer is rotated around the first pivot, the corresponding pin moves the interlock member in a direction perpendicular to each limiting hole, thereby moving the other pin to rotate the second joint washer around the second pivot.

Abstract: A wire-passable hinge is mounted between a first casing body and a second casing body. The first casing body and the second casing body are electrically connected to each other by a conductive wire. The wire-passable hinge includes a rotary rod that has a wire passageway to allow passage of the conductive wire, and a bushing that is sleeved rotatably on the rotary rod. A first hinge casing is connected to the first casing body. The rotary rod extends into the first hinge casing. The first hinge casing further allows the conductive wire to pass therethrough. A second hinge casing is connected to the second casing body. The bushing is disposed within the second hinge casing. The second hinge casing further allows the conductive wire to pass therethrough.

Abstract: A hinge is connectable with two housing shells for permitting relative opening and closing of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and a center support plate. The rotating units are disposed at two sides of a centerline of the fixed seat and are connectable with the housing shells. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member arcuately slidable on the fixed seat. The lateral support plates are mounted on the linking members, and have central notches. The center support plate is movably disposed on the fixed seat and is moved with the rotating units. In the open state, the center support plate is disposed in the central notches. In the closed state, the center support plate abuts against the fixed seat.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. An outer rail of the outer section has a sliding surface and an anti-retraction block and a releasing block formed on the sliding surface. A middle rail of the middle section is slidably disposed on the outer rail. An anti-retraction member and a driven member are pivotably mounted on an end of the middle rail. An inner rail of the inner section is slidably disposed on the middle rail, and has an abutment plate and a driving plate formed on an inner surface of the inner rail. The abutment plate abuts upwardly against the anti-retraction member, and is moved to disengage from the anti-retraction member to permit abutment of the anti-retraction member against the anti-retraction block so as to prevent retraction movement of the middle section relative to the outer section.

Abstract: A hinge device includes a fixed shaft, a rotating sleeve, a fixed connection member, a torsion spring, a rotating connection member and a friction resistance assembly. The rotating sleeve is rotatably mounted on the fixed shaft and is located between a fixed end and a free end. One end of the fixed connection member is fixedly connected to the free end, and the other end is provided with a first slot. Two ends of the torsion spring are respectively equipped with a first snap-in pin and a second snap-in pin. The first snap-in pin inserts into the first slot. An extension part protrudes from a fixed part of the of the rotating connection member and is provided with a second slot. The second snap-in pin inserts into the second slot.

Abstract: A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.
