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 portable information handling system supports a flexible OLED display film over housing portions rotationally coupled by a hinge by folding the OLED display film over the hinge. Hinge brackets that couple to the housing portions each have a helical member that extends into an associated helical guide of the hinge main body. Hinge bracket rotation translates through the helical guides for synchronized housing rotation. The hinge main body has first and second circular portions extending along its length to define first and second rotation axes about which the hinge brackets pivot so that the display film has space to fold in the closed position.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail slidably disposed on the outer section, a ball sliding plate slidably disposed on the middle rail, and a leaf spring at one end of the middle rail. The ball sliding plate has a plate body, a synchronizing block and a positioning hole formed on the plate body. The inner section includes an inner rail and a synchronizing actuating member pivotably mounted to the inner rail. The synchronizing actuating member is in an abutting engagement with the synchronizing block during an extended movement of the inner section relative to the middle section to make synchronizing movement of the ball sliding plate with the inner section until the positioning hole of the ball sliding plate is engaged with the leaf spring.

Abstract: Embodiments of synchronized hinges for foldable displays are described. In some embodiments, a hinge may include: a first bracket coupled to a first shaft via a first arm, a second bracket coupled to a second shaft via a second arm, and a synchronization bracket coupled to the first and second shafts.

Abstract: A hinge includes: a base seat that includes a rack extending in a front-back direction; a moving platform that is movable on the base seat along the front-back direction; and a shaft unit that includes a rotating shaft rotatably extending through the moving platform in a left-right direction, a main gear member rotatably extending through the moving platform, co-movable with the moving platform, and meshed with the rack to constitute a rack and pinion system, and a first bevel gear piece fixedly sleeved on the rotating shaft, and meshed with the main gear member such that rotation of the rotating shaft results in collective linear front-back motion of the shaft unit and the moving platform relative to the base seat.

Abstract: A hinge includes a base frame unit and a rotating unit. The base frame unit includes a base seat having two rotating recesses and a transmitting recess, and two interfering plates respectively disposed in the rotating recesses. The rotating unit includes two rotating members respectively and rotatably disposed in the rotating recesses, and a bevel gear member disposed in the transmitting recess. Each rotating member frictionally interferes with the respective interfering plate, and has a bevel gear portion meshing with the bevel gear member. A torque generated as a result of rotation of one rotating member is transmitted through the bevel gear member to rotate the other rotating member relative to the base seat so as to make stable synchronous rotation of the rotating members.

Abstract: A hinge assembly is provided for hingedly connecting a first frame to a second frame, and includes at least one hinge module which includes a first mounting base, a first connection member, a second connection member, and a transmission unit. The first and second connection members are coupled to the first and second frames, respectively, and are turnably mounted to the first mounting base respectively about first and second turning axes which are parallel to and offset from each other. The transmission unit is provided to permit the first and second connection members to turn in opposite rotational directions from each other whilst turning simultaneously.

Abstract: A hinge assembly includes first and second linkage rods pivoted to a base seat, a cam connected to the first and second linkage rods, and a kickstand support pivoted to the cam. A latch is disposed in the cam. When the first and second linkage rods, the kickstand support, and the cam are received inside the base seat, the latch is in a first locking position, where the latch locks rotational movement of the kickstand support relative to the cam. When the second linkage rod moves outward of the base seat and brings the first linkage rod to rotate relative to the cam, the latch is pushed by the kickstand support to move into a second locking position, where the first linkage rod is limited from rotating relative to the cam.
