A non-protruding connecting structure allowing zero to 360 degrees and any intermediate angle of relative rotation between two display screens includes a hinge assembly, a first shaft body, a second shaft body, and a fixing member. The hinge assembly includes first and second wheels sleeved on first and second shaft bodies, and an enmeshed worm engaged with the first and second wheels. A central axis of the first wheel is parallel to that of the second wheel. The axis of the worm is perpendicular to that of the first and second wheels. A rotation direction of the first wheel is opposite to that of the second wheel. The fixing member fixes the hinge assembly. An electronic device including the connecting structure is also disclosed.

A hinge has two arms that can be pivoted relative to one another between a closed initial position and a second position. A first arm has a first guide slide. A second guide slide can be shifted along the pivot axis and can contact the first guide slide. When the two arms are moved towards the initial position, at least one cylinder-piston unit can be loaded by means of the second guide slide. The second guide slide can be rotationally fixedly coupled to the second arm in a first pivoting angle sub-range bordering the initial position and to the first arm in a second pivoting angle sub-range bordering the second position. The hinge has a first control slide rigidly connected to the second arm and a second control slide that makes contact with the first control slide and that is coupled against rotation to the first guide slide.

A torque-variable single-shaft rotary shaft structure with multiple frictional pairs includes a pivot shaft. A first support is secured to a pivot shaft and a second support is disposed on the pivot shaft. An adjustment wheel assembly, a frictional assembly and an elastic assembly are fitted on the pivot shaft. The adjustment wheel assembly and the frictional assembly have a first adjustment wheel and a second frictional member synchronously movable with the first support and a second adjustment wheel and a first frictional member synchronously movable with the second support. When the first and second supports are rotated, the first and second adjustment wheels are driven to contact and abut against each other so as to provide axial action forces. The frictional assembly has multiple first and second frictional members, which are alternately arranged in frictional contact with each other to form multiple frictional pairs.

A non-protruding connecting structure allowing zero to 360 degrees and any intermediate angle of relative rotation between two display screens includes a hinge assembly, a first shaft body, a second shaft body, and a fixing member. The hinge assembly includes first and second wheels sleeved on first and second shaft bodies, and an enmeshed worm engaged with the first and second wheels. A central axis of the first wheel is parallel to that of the second wheel. The axis of the worm is perpendicular to that of the first and second wheels. A rotation direction of the first wheel is opposite to that of the second wheel. The fixing member fixes the hinge assembly. An electronic device including the connecting structure is also disclosed.

A hinge device is adapted to be installed between two machine bodies that are mounted with a flexible display. The hinge device includes a base member, two rotating modules mounted respectively to opposite sides of the base member and adapted for the machine bodies to be mounted respectively thereto, and a central support plate disposed above the base member and connected between the rotating modules. The central support plate is drivable by the rotating modules to move relative to the base member from a supporting position, where the flexible display is flat and is supported thereby from below, to a receding position, where a display receiving space is provided for receiving a bent portion of the flexible display.

Various vehicle hinge improvements are enabled herein. For instance, a hinge assembly comprises a body-side base plate. The body-side base plate comprises a body-side adjustment block extending perpendicularly away from a flat surface portion of the body-side base plate, a first body-side threaded hole received in the body-side adjustment block, and a second body-side threaded hole received in the body-side adjustment block. A first body-side adjustment bolt is received through a first body-side adjustment channel and threaded into the first body-side threaded hole, wherein rotation of the first body-side adjustment bolt facilitates adjustment of a body-side hinge member in a first direction. A second body-side adjustment bolt is received through the second body-side adjustment channel and threaded into the second body-side threaded hole, wherein rotation of the second body-side adjustment bolt facilitates adjustment of the body-side hinge member in a second direction.

A portable information handling system housing rotationally couples housing portions with a dual axis synchronized gear to rotate about parallel spaced axes that define a radius to support folding of a flexible display. Each axis of the synchronized gear couples to a housing portion with a sliding bracket that adjusts length during rotation. Plural pivot arms couple to a main body of the hinge at the first and second axes and to the housing portions to manage spacing of the housing portions during rotation. A sliding member coupled to the main body engages with the plural pivot arms to synchronize rotation of the plural pivot arms and regulate torsional forces related to rotation of the housing portions that can damage a display film folding at the hinge.

A second body-side adjustment bolt is received through the second body-side adjustment channel and threaded into the second body-side threaded hole, wherein rotation of the second body-side adjustment bolt facilitates adjustment of the body-side hinge member in a second direction.

A refrigerator includes a cabinet defining a chilled chamber, an enclosure housing positioned within the chilled chamber, the enclosure housing defining an enclosure and a docking port configured for receiving a water filter, and a door assembly for providing selective access to the enclosure. The door assembly includes an access door pivotally mounted to the enclosure housing, a guide pin mounted to the enclosure housing, a guide bar having a first end and a second end opposite the first end, the first end being pivotally mounted to the access door and the second end defining a slot having the guide pin slidably received therein, a friction washer mounted on the guide pin adjacent the guide bar; and a spring member mounted on the guide pin and being configured for urging the friction washer against the guide bar to resist motion of the access door.

A hinge capable of widely expanding includes an arc-shaped guide member, two movable members and two torsion generating members, wherein first guide rails are formed on two sides of the arc-shaped guide member, and a circular displacement track is defined by an arc center of the arc-shaped guide member. Each of the two movable members, respectively positioned on two sides of the arc-shaped guide member, is provided with a working surface contacting one of the first guide rails and an arc-shaped through hole penetrating therethrough. The arc center of the arc-shaped through hole is the same as the arc-shaped guide members'. Each of the two torsion generating members is assembled to the arc-shaped guide member through the arc-shaped through hole to which one of the two movable members belongs. The two movable members are guided by the arc-shaped guide member to move on the circular displacement track.
