A double-axis hinge structure including a fixing member, a first shaft, a first guiding portion, a second shaft, a second guiding portion, and a slide guiding member is provided. The first shaft and the second shaft pass through the fixing member and the slide guiding member. The first guiding portion and the second guiding portion are respectively integrally formed on the first shaft and the second shaft. The slide guiding member has a third guiding portion and a fourth guiding portion. When one or both of the first shaft and the second shaft rotates relative to the fixing member, the guidance between the first guiding portion and the third guiding portion and/or the second guiding portion and the fourth guiding portion drives the slide guiding member to slide, so that the first shaft and the second shaft synchronously rotate in opposite directions by the same amount of rotation.

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.

Embodiments provide for a handheld device with a unified desktop for integrating the functionality of the handheld device with a larger computer system. When connected to a peripheral display and/or a display of the larger computer system, the handheld device provides a unified desktop displayed across the screen(s) of the handheld device and the peripheral display. The unified desktop unifies the functionality provided by the larger computer system and the handheld functionality, e.g., communication applications (e.g., phone, SMS, MMS). A user can seamlessly interact with applications, e.g., open, move, close, receive notifications, on the unified desktop whether the applications are displayed on the screens of the handheld device, or the peripheral display of the larger computer system.

An example electronic device may comprise a first housing including a first surface and a second surface facing in a direction opposite the first surface, a second housing including a third surface and a fourth surface facing in a direction opposite the third surface, a hinge disposed between the first housing and the second housing configured to provide rotational motion between the first housing and the second housing, and a flexible display disposed from the first surface of the first housing across the hinge to the third surface of the second housing, at least part of the flexible display configured to form a curved surface as the hinge structure is folded, wherein the hinge may include dual-axis hinges configured to provide a first rotational axis allowing the first housing to rotate about the second housing and a second rotational axis allowing the second housing to rotate about the first housing and slides coupled with the first housing and the second housing and configured to provide sliding motion perpendicular to a lengthwise direction of the first housing and the second housing.

There is disclosed in one example, an encasement for a mobile computer, including: an external casing in a clamshell form factor, the external casing including a base, a secondary display chassis hingedly connected to the base at a secondary hinge, and a primary display chassis hingedly connected to the secondary display chassis at a primary hinge disposed at a removed edge of the secondary display chassis from the secondary hinge, the primary display chassis to substantially overlay the secondary display chassis and the base when the primary hinge is in a closed position; and pivot means disposed to substantially bias the secondary hinge against movement from a selected position in at least one direction in the absence of an electrical input.

A rotary shaft link assembly structure is connected between a first support and a second support of two articles. The rotary shaft link assembly structure has a rotary shaft assembly and at least one synchronous rotational assembly. The rotary shaft assembly has multiple connection members side-by-side disposed between the first and second supports. Each connection member is correspondingly formed with at least one hollow section. The synchronous rotational assembly passes through the hollow sections of the connection members to respectively connect with the first and second supports, whereby the connection members are transversely serially connected to drivingly bend and connect along with the synchronous rotational assembly. The connection members respectively shield a part of the synchronous rotational assembly to provide a protection effect and reduce the dropped powder and oil leakage caused by the friction.

A hinge system has a first body and a second body rotatably connected to one another around a first pivot point. The second body has a top surface and bottom surface positioned opposite one another in a vertical direction of the second body. A translation mechanism is connected to the second body and the first pivot point to displace the first pivot point in the vertical direction relative to the second body.

A support structure is provided, which includes a first support having a first supporting surface, a second support having a second supporting surface, and a third support having a third supporting surface. The first support is provided with a first connecting portion. The second support rotatably fits with the first support about an axis of rotation. The second support is provided with a second connecting portion. The first connecting portion and the second connecting portion are both spaced apart from the axis of rotation. The third support is rotatably connected to both the first connecting portion and the second connecting portion. When the support structure is in a folded state, the first supporting surface and the second supporting surface are spaced apart from the third supporting surface, and the first supporting surface and the second supporting surface each form a specific included angle with the third supporting surface.

A hinge mechanism being used for a foldable electronic device is provided. The foldable electronic device comprises a first panel body and a second panel body, which are pivotable with respect to each other The hinge mechanism comprises a central plate, a first pivoting element and a second pivoting element. The central plate comprises a first curved section and a second curved section. The first pivoting element is fixed to the first panel body and grips the first curved section. The second pivoting element is fixed to the second panel body and grips the second curved section. When the first pivoting element and the second pivoting element switch between a retracted position and a stretched position, the first panel body and the second panel body change between an unfolded status and a folded status correspondingly.

Examples of hinge assemblies are described. In an example implementation, a hinge assembly includes hinge elements which are interconnected to move the hinge assembly between a folded position and an unfolded position. The hinge assembly further includes elastic members disposed between the hinge elements at a first side and a second side thereof. When the hinge assembly is moved from the unfolded position towards the folded position, elastic members at the first side are decompressed and elastic members at the second side are stretched. When the hinge assembly is moved from the folded position towards the unfolded position, elastic members at the first side are compressed and the elastic members at the second side are destretched.
