Abstract: A foldable module and a corresponding device are provided. The foldable module includes a first connection part, a first pin, a first drive ring, and a first spring. The first pin passes through the first drive ring, a first pin hole which is disposed on the first connection part, and the first spring. A first convex part and a first concave part are disposed between the first drive ring and the first connection part. The first convex part is located between (a) the first spring and (b) the first concave part or the first convex part. When the first connection part rotates, or in a folding or unfolding process, the first convex part slides out of the first concave part, to provide damping force for unfolding or folding. The first connection part directly drives the first convex part and the first concave part to move correspondingly, thereby improving transmission accuracy.

Abstract: This application provides a rotation shaft structure and an electronic device. The rotation shaft structure includes a main shaft assembly, and two folding assemblies. The folding assembly includes a rotation assembly, a support plate, and a housing mounting bracket. The rotation assembly is rotationally connected to the main shaft assembly. The support plate is rotationally connected to the housing mounting bracket and slidably connected to the rotation assembly. When two housing mounting brackets rotate toward each other, two support plates rotate in a same direction relative to the housing mounting brackets on corresponding sides, so that the two support plates and the main shaft assembly can form a triangle-like display accommodation space. When the electronic device is in a closed state, the display accommodation space can be used for accommodating a bent portion of the flexible display, so that the flexible display is not damaged by extrusion.

Abstract: A hinge and a mobile terminal to resolve poor use effect of a foldable electronic device. The hinge includes a main body, and a first folding assembly and a second folding assembly that are symmetrically disposed along the main body. When the first folding assembly and the second folding assembly are rotated toward each other, a length of the hinge can be extended, and an accommodation space for accommodating the flexible display can be formed. When the first folding assembly and the second folding assembly are rotated away from each other, the length of the hinge can be reduced, and a support surface for supporting the flexible display can be formed, so that the flexible display cannot be stretched, compressed, or the like during folding and unfolding, thereby improving the use effect and safety of the mobile terminal.

Abstract: Embodiments provide a rotating shaft mechanism applicable to the field of foldable displays of electronic device technologies. The rotating shaft mechanism includes a main body, a first support plate, a second support plate, a middle support plate, a first swing arm, and a second swing arm. The first swing arm, the main body, and the first support plate may form a slider-crank, and the second swing arm, the main body, and the second support plate also form a slider-crank. The middle support plate may move relative to the main body when driven by at least one of the first support plate, the second support plate, the first swing arm, or the second swing arm.

Abstract: This disclosure relates to a folding module and a foldable electronic device. A first protrusion and a first sliding slot are provided between a drive portion and a first connection member. A second protrusion and a second sliding slot are provided between the drive portion and a second connection member. A first drive spring and a second drive spring press against the drive portion. In a process in which the first support member folds or unfolds relative to the second support member, folding or unfolding can be implemented provided that the first support member and the second support member rotate by a relatively small angle, so that a speed of folding or unfolding of the first support member relative to the second support member is increased.

Abstract: A folding apparatus includes a first housing, a first support plate, a middle housing, a first mounting bracket, a first transmission arm, and a first rotating arm. The first mounting bracket is fixed to the first housing, the first transmission arm is rotatably connected to the middle housing, a rotation center is a first axis, and the first transmission arm is slidably connected to the first mounting bracket and slidably connected to the first support plate. The first rotating arm is rotatably connected to the middle housing, a rotation center is a second axis, the first rotating arm is rotatably connected to the first mounting bracket, and the second axis and the first axis are not collinear. The first support plate is rotatably connected to the first mounting bracket, so that the first housing and the first support plate switch between a flattened state and a folded state.
