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 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: An electronic device includes a base cover, a cover plate which is slidable relative to the base cover among a closed position, an open position, and a transition position, and a slide positioning mechanism which is configured for positioning the cover plate relative to the base cover, and which has first and second magnetically attractive units. When the cover plate is in a selected one of the closed and open positions, a magnetically attractive force is generated to position the cover plate in the selected one of the closed and open positions. When the cover plate is in the transition position, a magnetically repulsive force is generated to facilitate movement of the cover plate away from the transition position.

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 hinge includes a seat, a shaft, a swivel bracket and at least one limiting bar. The seat includes two support portions. An accommodation area is defined between the two support portions. The two support portions are respectively provided with a shaft hole. The two shaft holes are arranged coaxially and connected to the accommodation area. The shaft includes a coupling section and two pivoting sections. The coupling section is located between the two pivoting sections. The two pivoting sections are respectively provided in one of the two shaft holes in a rotatable manner, and the coupling section is in the accommodation area. The swivel bracket includes a mounting plate, a sleeve piece and at least one extension portion. The mounting plate includes an inner surface, an outer surface, and a bottom edge. The sleeve piece extends from the bottom edge of the mounting plate and is wound at a side corresponding to the inner surface. The sleeve piece is configured to be sleeved over and fixed to the coupling section, such that swivel bracket is fixed to the shaft and rotatable with respect to the seat to move the inner surface to face the accommodation area. The extension portion is adjacent to lateral edges of the sleeve piece and extends from the bottom edge and is bent towards the side corresponding to the inner surface. The limiting bar is disposed on one of the two support portions and is in the accommodation area. The limiting bar is in a rotational path of the extension portion. When the swivel bracket is flipped outward with respect to the seat, the extension portion moves towards the limiting bar.
