Abstract: A hinge structure includes: a supporting sheet having an unfolded, flattened state and a folded state; at least one first hinge connected to the supporting sheet, the at least one first hinge being configured to drive the supporting sheet to switch between the unfolded, flattened state and the folded state; at least one flattening support including a first support, a second support, and a flattening bracket, the flattening bracket being connected to the first support and the second support, the flattening bracket being connected to the supporting sheet. When the supporting sheet is in the unfolded, flattened state, the first support and the second support interact with each other and generate a force parallel to a plane where the supporting sheet is located, to maintain the supporting sheet in the unfolded, flattened state.

Abstract: An accommodating cylinder, a touch pen assembly, and a protective case are provided. The accommodating cylinder includes a cylinder body, a first magnetic member, a second magnetic member and a pen base. The cylinder body has an accommodating cavity. The first magnetic member is configured to generate a first magnetic field, and is arranged in the accommodating cavity. At least one of the first magnetic member and the second magnetic member is a coil, and the second magnetic member is arranged in the accommodating cavity and movable between a retracted position and an extended position. The pen base is connected with the second magnetic member. The second magnetic member is configured to move relative to the first magnetic member from the retracted position to the extended position, and to drive the pen base to move from an inserted position to a pop-up position in a first power-on state.

Abstract: A hinge includes: a trajectory limiting mechanism, including a first slider and a second slider; a first hinge bracket, for cooperating with the first slider and the second slider, the first hinge bracket being configured to limit rotation trajectories of the first slider and the second slider; a synchronization mechanism, cooperating with the trajectory limiting mechanism, for driving the first slider and the second slider into rotation relative to the first hinge bracket in a preset direction respectively; and a locking mechanism, cooperating with the synchronization mechanism, the locking mechanism having a locked state in which the locking mechanism is configured to prevent movement of the synchronization mechanism to maintain a relative positional relationship between the first slider and the second slider.

Abstract: The disclosure relates to a rotating component and a terminal device. The rotating component includes: a hinge bracket; a movable strip disposed on the hinge bracket, the movable strip including a first meshing portion facing toward the hinge bracket and a second meshing portion facing away from the hinge bracket. The rotating component further includes two rotating structures, where the first rotating structure is disposed on one side of the movable strip and meshed with the first meshing portion, and the second rotating structure is disposed on another side of the movable strip and meshed with the second meshing portion. When the movable strip moves, the two rotating structures rotate synchronously in opposite rotation directions.
