Abstract: A hinge is mountable between two casing parts of a flexible electronic device, and includes a base seat and two rotating modules disposed at two sides of the base seat for respectively mounting the casing parts thereon. Each rotating module includes a primary support plate pivotably connected to the base seat, and a secondary support plate pivotably connected to the primary support plate. When the rotating modules are rotated from an initial position, where the secondary support plates are flush with the primary support plates for resting and supporting a flexible display thereon, to a terminal position, where the secondary support plates are turned away to provide a leeway, the casing parts are shifted from an unfolded state to a folded state.

Abstract: A hinge mechanism includes a base gudgeon and a pivot pintle. The base gudgeon has a main body and first and second tubular portions formed on the main body and respectively having coaxial first and second pivot holes. The second tubular portion has a first torque regulating formation formed on an inner surrounding wall thereof. The pivot pintle has a first pintle section rotatably inserted into and pressed-fit to the first pivot hole to produce primary frictional torque during pivoting of the pivot pintle, a second pintle section rotatably inserted into and pressed-fit to the second pivot hole to produce secondary frictional torque, and a second torque regulating formation configured to be matingly engaged with the first torque regulating formation in a part of angular positions of the pivot pintle so as to reduce the secondary frictional torque.

Abstract: A supporting device includes a dual-shaft hinge module and two buffering modules respectively arranged at two opposite sides of the dual-shaft hinge module. Each dual-shaft hinge module includes two shafts, a linking member clamped between the two shafts, and two side wing members respectively and slidably installed on the two shafts. The two buffering modules are respectively installed on the two shafts and are respectively cooperated with the two side wing members. Each buffering module includes an internal connecting member fixed on and synchronously rotatable with the corresponding shaft and an external connecting member slidably disposed on the internal connecting member and provided to be fixed on a carrying plate. Each side wing member has a limiting portion passing through the corresponding internal connecting member and the corresponding external connecting member.

Abstract: A hinge mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.

Abstract: A bendable support apparatus includes a support unit, at least one coaxially pivoting unit and at least one synchronously pivoting unit. The support unit includes a plurality of support members extending in a first direction and juxtaposed to each other. Each support member has opposite support and mounting major surfaces. The support major surfaces cooperatively define a support surface for a flexible display attached thereto. The coaxially pivoting unit includes a plurality of coaxially pivoting assemblies disposed to permit two adjacent support members to be coaxially pivoted to each other about a pivot axis at a neutral layer of the flexible display. The synchronously pivoting unit includes a plurality of synchronously pivoting assemblies each disposed among three adjacent support members to permit two lateral support members to be synchronously pivoted relative to a middle support member so as to shift the bendable support apparatus between unfolded and folded states.

Abstract: A bendable displaying apparatus of the present disclosure includes two housings, a supporting device, and a bendable display. The supporting device is fastened to the two housings and is arranged between the two housings. The supporting device includes a retainer, two supporting units, a first supporting plate, and two second supporting plates. The bendable display is disposed on the two housings, the first supporting plate, and the two second supporting plates. When the two housings are moved to stack with each other, the two housings drive the two supporting units to move the two second supporting plates along a direction away from each other and drives the retainer to downwardly move the first supporting plate, so that the two second supporting plates and the first supporting plate jointly form a space that provides the bendable display to deform therein.

Abstract: A bendable display apparatus includes two supporting devices and a bendable display mounted on the two supporting devices. Each supporting device includes a dual-shaft driving module and two buffering modules respectively arranged at two opposite outer sides of the dual-shaft driving module. The dual-shaft driving module includes two shafts parallel to each other and a synchronizing member sandwiched between the two shafts. Each buffering module includes an internal connecting member fixed on the synchronizing member, an external connecting member slidably disposed on the internal connecting member, and a linkage mechanism configured to be driven by the synchronizing shaft for moving the external connecting member relative to the internal connecting member. When the dual-shaft driving modules are rotated, the bendable display is bent while a length of the bendable display remains constant, and each external connecting member is moved relative to the corresponding internal connecting member.

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.
