An electronic device is disclosed, including: a first housing, a second housing, a folding housing that pivotably connects the first housing and second housing, a flexible display spanning the first, second and folding housings, a printed circuit board (PCB), a first camera module at least partly visible through a surface of the second housing, a first magnet disposed in the first housing, a second magnet disposed in the second housing, and a hall sensor disposed on the PCB, the hall sensor configured to detect magnetic flux caused by motion of the first and/or second magnet in folding and unfolding of the electronic device so as facilitate determination of a configuration state of the electronic device.

This application provides a display module and an electronic device. A display module includes a first buffer member, and a first non-bending region, a bending region, and a second non-bending region. A support member is fastened on the display screen. A first metal plate member of the support member faces the first non-bending region. A first connection plate member of the support member faces the bending region. A second metal plate member of the support member faces the second non-bending region. The first connection plate member is provided with. Openings of the grooves are located on a first surface of the metal part. Organic material are located in the grooves, and are connected to the metal part. The first buffer member is located between the first metal plate member and the second metal plate member.

A hinge of a computing device includes a primary support connecting a display to a stand. As the display rotates about the stand, the primary support slides along a friction strip, which stabilizes the display with respect to the stand. A stabilizer may connect the stand to the base or the stand to the display.

Described are a rotary shaft kit and an electronic device. The rotatory shaft kit includes: a rotatory shaft assembly, including a protective shell and a first bracket; two rotating assemblies and two housing assemblies. One of the two rotating assemblies is arranged on a side of the rotatory shaft assembly, and the other is arranged on another side; each rotating assembly includes a rotating plate, a first rotating member, and a second rotating member; the first rotating member is connected to the rotating plate at an end of the rotating plate, and the second rotating member is connected to the rotating plate at another end of the rotating plate. One of the two housing assemblies is arranged on the side of the rotatory shaft assembly, and the other is arranged on the another side; each housing assembly includes a second bracket and a fixing plate connected to the second bracket.

An electronic device is provided. The electronic device includes a first foldable main body, a second foldable main body disposed on a side of the first foldable main body, a rotating shaft disposed between the first foldable main body and the second foldable main body and configured to rotationally connect the two foldable main bodies, and a detection assembly configured to detect a relative angle between the two foldable main bodies.

A hinge assembly includes: a fixed supporting piece; a rotating assembly, movably connected with the fixed supporting piece and including a first limiting portion; and a locking mechanism, disposed on the fixed supporting piece and including a limiting piece which includes a second limiting portion matched with the first limiting portion. The fixed supporting piece slides relative to the rotating assembly in a direction perpendicular to an axial direction of the rotating assembly in a rotation process of the rotating assembly, so that the first limiting portion is connected with the second limiting portion or the first limiting portion is separated from the second limiting portion; when the first limiting portion is connected with the second limiting portion, the two limiting portions are matched with each other to limit rotation of the rotating assembly; when separated, limiting of the rotating assembly is released.

Enclosure covers for mobile computing devices are often formed from planar sections of sheet metal that form opposing outer-most layers thereof. The enclosure covers generally enclose and protect internal components. Enclosure covers for mobile computing devices are typically made from planar extrusions of aluminum with subsequent computer numerical control (CNC) machining and other processing steps to achieve complex shapes. Machining can be particularly wasteful of material and numerous processing steps are time-consuming and costly. The presently disclosed variable thickness enclosure covers sourced from extruded sheets of variable thickness reduce or eliminate machining and other processing steps typically required to achieve a desired complex shape. This is accomplished by extruding a shape closer to the desired shape of the variable thickness enclosure cover than presently known.

A foldable display device may have housing portions coupled by a hinge. The hinge may have a series of interconnected links. The links may be formed from interdigitated fingers in a friction clutch. The fingers or other portions of the links may be provided with crescent-shaped slots that receive pins. During folding of the device, the pins may slide along the crescent-shaped slots, thereby ensuring that adjacent links rotate relative to each other about a rotation axis that lies outside of the hinge and within a flexible display panel. Links may also be formed from link members with curved mating bearing surfaces that slide relative to each other as adjacent links are rotated relative to each other. A housing rotation synchronization mechanism may be formed using a set of gears that extends between the first and second housing portions.

A display device which includes a display panel and a protection member above the display panel. The protection member may include an adhesive layer above the display panel, a first protection layer above the adhesive layer, and a second protection layer between the first protection layer and the adhesive layer. The first protection layer may have a first thickness and a first modulus, and the second protection layer may have a second thickness less than the first thickness and a second modulus less than the first modulus. The minimum value of the second thickness may be 20 μm, and the maximum value of the second thickness may satisfy Equation (1) below. The display device, which includes the protection member including the second protection layer satisfying Equation (1), may improve impact resistance and maintain reliability.
