A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.

An electronic device is provided. The electronic device includes a housing including first and second housings, a display including a first display region connected to the first housing and a second display region connected to the second housing, and a hinge module connected to the first housing and the second housing. The hinge module may include a rotation bracket including a first accommodation space providing a first rotation axis and a second accommodation space providing a second rotation axis, a rotation member including a first rotation member connected to the first display region and a second rotation member connected to the second display region, and a rail member including a first rail member connected to the first rotation member and configured to rotate in the first accommodation space, and a second rail member connected to the second rotation member and configured to rotate in the second accommodation space.

A hinge is connectable with two housing shells for permitting relative folding and unfolding of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and at least one synchronous driving unit. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member fittingly and arcuately slidable on the fixed seat, a sliding member fittingly and arcuately slidable on the linking member, and a rotary bracket pivotably mounted on the fixed seat and inclinedly slidable on the sliding member. The lateral support plates are respectively mounted on the linking members. The synchronous driving unit includes two inboard pinions and two outboard pinions arranged laterally to mesh with bracket toothed portions of the rotary brackets to make synchronous rotation of the rotary brackets in opposite rotational directions.

The present application provides foldable hinge and a foldable display device. The foldable hinge includes a first support plate, wherein the first support plate is provided with at least two opposite arc-shaped grooves; two second support plates located on opposite sides of the first support plate; and at least two rotating mechanisms including a fixed plate fixed on one of the second support plates; and an arc-shaped arm connected to the fixed plate, wherein the arc-shaped arm is at least partially received and slided in the arc-shaped groove to drive the corresponding second support plate being unfolded or folded relative to the first support plate.

A switched-mode light-emitting diode (LED) display unit satisfying fire-fighting smoke exhaust and ventilation requirements includes an LED display unit, a mounting member, an opening-closing actuator and a pressing member. The LED display unit is mounted on the mounting member and the mounting member is mounted on a display panel by an opening-closing actuator and pressed against the display panel by a pressing member. The switched-mode LED display unit provides the pressing member that works to release the pressed mounting member after obtaining a triggering command and the opening-closing actuator that turns on the LED display unit subsequently, thereby meeting the fire smoke exhaust ventilation requirement of the internal surface or the external surface of a building.

An assembly includes a cover receiving frame having a first hinge portion thereon, the first hinge portion having a generally c-shape and a plurality of alternating supports positioned along a bottom portion of the first hinge portion. The assembly further includes a cover having a second hinge portion thereon for interconnection with the first hinge portion. The second hinge portion includes an elongated member for fitting generally within the c-shape and a plurality of alternating cutouts positioned along the elongated member. The assembly is assembled by positioning the cover parallel to the cover receiving frame and rotating the cover until it is captive.

The invention is directed to stands and methods for making the same. The stand is provided to hold an item such as an electronic device and/or a document. The stand may include (1) a base plate provided to support the stand on a support surface and/or by a user holding the base plate; (2) a plurality of hinge assemblies connected to the base plate; and (3) a platform assembly pivotally connected to the hinge assemblies, such that the angular disposition of the platform assembly is adjustable relative to the base plate.

A locking hinge is provided. The hinge includes axially aligned pins attached to a first leaf and corresponding spaced knuckles attached to a second leaf. Each pin is designed for one-way insertion into one of the corresponding knuckles. Once inserted, each pin is locked in an axially fixed position relative to each knuckle.

The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion that defines a channel. The example can also include a hinge assembly rotatably coupling the first portion and the second portion, the hinge assembly including a hinge arm that is fitted to the channel and retained in the channel by a state-transitionable material.

According to an aspect, a device may include a deployable rolling joint having a first deployable joint member, a second deployable joint member, and a plurality of flexures coupled to the first deployable joint member and the second deployable joint member. The deployable rolling joint may move from an undeployed state to a deployed state in which the first deployable joint member forms a convex surface portion and the second deployable joint member forms a convex surface portion. When the deployable rolling joint is in the deployed state, the convex surface portion of the first deployable joint member may roll with respect the convex surface portion of the second deployable joint member, and the plurality of flexures may hold the first deployable joint member and the second deployable joint member together as the first deployable joint member and the second deployable joint member roll across each other.
