A single-axis hinge includes a base, a movable plate, a limiting block, a rotating shaft and a stand set. The base includes a first shaft mounting hole, a stand drive shaft mounting hole and a path. The movable plate is formed with a second shaft mounting hole and a limiting notch. The limiting block is installed in the path. The rotating shaft passes through the first and second shaft mounting holes and includes a driving block and a first cam. An edge of the driving block is formed with a transmission teeth portion not completely surround the edge. The stand set includes a stand drive shaft disposed in the stand drive shaft mounting hole, and a support stand driven by the stand drive shaft. The stand drive shaft includes a gear and a second cam formed with a positioning notch.

A hinge includes two rotatable axle units each having two hinge shafts, two synchronizing units each disposed to make synchronous rotations of the hinge shafts, two movable bracket units each having a turnable base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two guiding bracket units, each having male and female arms respectively connected with two movable plates, and a plurality of guiding connecting members interposed between the arms. Each guiding connecting member has a protrusion and a sliding groove, and is angularly movable with the rotations of the hinge shafts. Removal of the protrusion from the sliding groove of an adjacent guiding connecting member is prevented by means of engagement of an abutting portion of the protrusion with an abutted block in the groove.

A hinge device for supporting an electronic device includes a first portion and a second portion movable relative to the first portion with a biasing element supported by one or the first portion or the second portion. The first portion has an arcuate groove, and the second portion has an arcuate rail configured to complementarily mate with the arcuate groove and slide therein. The biasing element contacts a leading edge of the other of the first portion or second portion, and the first portion and second portion are bistable in a closed state relative to one another and an open state relative to one another based at least partially on a surface profile of the biasing element applying a radial force to the leading edge.

Provided is a rotating shaft mechanism of an electronic device. A first fixing assembly and a second fixing assembly in the rotating shaft mechanism are connected to each other by a first connector and a second connector. A hollow region can be reserved in the rotating shaft mechanism as the first connector and the second connector may be shorter. Thus, an external circuit of the electronic device can pass through the hollow region and be disposed in a second body of the electronic device. An electronic device are also provided.

A hinge includes two rotatable axle units disposed on a base seat and each having two rotatable hinge shafts, two movable bracket units each including a base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two synchronizing units for making synchronous rotations of the hinge shafts. Each synchronizing unit includes a first gear member having two end surfaces in form of bevel gears, and two second gear members each meshing with the respective end surface and fitted to the respective rotary block. Rotations of the hinge shafts at one side of the base seat result in rotations of the rotary blocks and the second gear members, and bring in rotations of the second gear members, the rotary blocks and the hinge shafts at the other side to make the synchronous rotations.

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.

The present disclosure relates to an ambidextrous hinge. The ambidextrous hinge includes a first knuckle with a first engagement feature, a second knuckle with a second engagement feature, and a third knuckle movably coupled between the first knuckle and the second knuckle. The third knuckle includes a third engagement feature that engages the first engagement feature to cause the ambidextrous hinge to lock in a first open position when used as a first swing hinge. The third knuckle includes a fourth engagement feature that engages the second engagement feature to cause the ambidextrous hinge to lock in a second open position when used as a second swing hinge.

A housing unit of a display device according to an aspect of the disclosure includes a hinge member, a first housing, a second housing, a first lifter, a second lifter, and shafts. A link groove is provided in the first housing, a link groove is provided in the second housing, and in a state in which the housing unit is open at 180 degrees, the hinge member, the first lifter, and the second lifter are aligned on the same plane.

A foldable electronic device includes a first casing, a second casing, a hinge structure and a foldable display. The hinge structure connects the first casing and the second casing, and includes a plurality of supporting blocks, a plurality of first hinge blocks and a plurality of second hinge blocks. The supporting blocks are arranged side by side between the first casing and the second casing. The first hinge blocks and the second hinge blocks are respectively arranged at two sides of the supporting blocks. One of the first hinge blocks connects two of the supporting blocks adjacent to each other. One of the second hinge blocks connects two of the supporting blocks adjacent to each other. The foldable display includes a first bonding portion secured to the first casing, a second bonding portion secured to the second casing and a foldable portion aligned to the hinge structure.

A foldable display device includes a first support member and a second support member separated from each other and each including a short side and long side, a display module disposed on the first support member and the second support member, a hinge which couples a side of the first support member and a side of the second support member, a first rail disposed between the first support member and the display module and disposed along the long side of the first support member, and a second rail disposed between the second support member and the display module and disposed along the long side of the second support member, where the first rail and the second rail are slidable in a first moving direction and a second moving direction opposite to the first moving direction.
