An adapter device enabling a peripheral component interconnect express (PCIe) slot in a server to additionally accept an open compute project (OCP) card includes a bracket assembly compatible with an OCP card and a server. The adapter device comprises a chassis, a front-end bracket, an adapter assembly, and a rail assembly. The front-end bracket defines a first inserting port for OCP card insertion, the adapter assembly comprises OCP interface, adapter circuit board, and PCIe interface. The PCIe interface is connected to the adapter circuit board, and the adapter circuit board provides electrical connection and conversion between OCP interface and PCIe interface. The rail assembly between the front-end bracket and the OCP interface carries in the OCP card when the card is inserted.

An electronic device is provided. The electronic device includes a first frame including a first surface, a second surface facing the direction opposite to that of the first surface, and a side surface encompassing the space between the first surface and the second surface, a guide path which is formed in the space of the first frame and which includes, from the side surface toward the space, an external environment connection hole formed at a specified depth, a first through-hole formed from the second surface up to the external environment connection hole, and a second through-hole formed at a location apart from the first through-hole so as to be formed from the first surface up to the second surface, and a sealing member including a sound module disposed on the first surface so as to correspond to the second through-hole, and a recess which is disposed on the second surface and connects the first through-hole to the second through-hole.

An electric device includes: a housing having a first electrically conductive housing wall; and a first circuit board which is arranged in the housing and which has an electrical conductor. The first electrically conductive housing wall can be electrically conductively connected to the electrical conductor of the first circuit board by use of a screw connection.

A display panel and a display device are provided. Through setting an area difference between a first sub-display area and a second sub-display area in two directions of the display panel to be less than or equal to a preset value, an area difference between a force-receiving area of the first sub-display area and a force-receiving area of the second sub-display area will be less than or equal to a preset value such that force exerted on the first sub-display area and the second sub-display area is uniform, preventing concentrated force on one side of the display panel from causing the display panel to break.

An enclosure for electrical installations includes a bottom and a cover fastened to the bottom by a fastening device including a latch which, supported by a bearing, is turnable in relation to the bottom to open/close the fastening device. An arm is bearing-mounted to the latch. The cover has a detent to receive the arm and to fasten the cover to the bottom by the arm. The detent is located in a recess formed in an edge of the cover. Attached to the arm there is a cover piece to attach to the detent in the recess of the cover. The cover piece includes first and second outer surfaces which at the recess of the cover make the outer surfaces of the cover uniform, such that the discontinuities formed by the recess of the cover on its top and side surfaces are concealed.

The hinge assembly includes: a rotating assembly and a hovering mechanism. The rotating assembly includes a first rotating part, and the first rotating part comprises a first guide groove extending obliquely around an axial direction of the first rotating part. The hovering mechanism comprises a sliding member and a position limiting member. The sliding member includes a protruding part, the protruding part extends into the first guide groove. The first rotating part drives the sliding member to move along the axial direction of the first rotating part when rotating. One of the position limiting member and the sliding member comprises a first limiting part, the other of the position limiting member and the sliding member comprises a second limiting part cooperated with the first limiting part.

A computer device and a host module thereof are provided. The host module includes a case, a motherboard, and a power supply unit. The case includes a first side plate, a second side plate, a front panel, a rear panel, and a separation structure. The rear panel is located on an opposite side of the front panel. The first side plate, the second side plate, the front panel, and the rear panel enclose an internal space. The separation structure is located in the internal space, extends from the first side plate to the second side plate, and divides the internal space into a first part and a second part. The second part is located under the first part. The motherboard is disposed in the first part. The power supply unit is disposed in the second part, and is electrically connected to the motherboard.

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.

An electronic device is provided. The electronic device includes a first housing, second housing, a hinge structure rotatably connecting a side surface of the first housing and a side surface of the second housing facing the side surface of the first housing along a folding axis, a flexible display panel including a first display area, a second display area, and a third display area, and a supporting member supporting the flexible display panel. The supporting member includes a flexible region including plural openings having a length in a direction parallel to the folding axis, spaced apart from each other, and corresponding to the third display area, and rigid regions corresponding to the first display area and the second display area. Both ends of each of the openings partially overlapped on the plurality of gears are disposed outside the plurality of gears projected onto the support member.
