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: In a rotating shaft mechanism and a foldable mobile terminal, connecting rods and swing arms are rotatably connected to a main shaft assembly, and the swing arms and the connecting rods rotate around different axes, so that the swing arms and the connecting rods rotate and slide relative to each other. During folding, the connecting rods or the swing arms drive the two support plates to rotate towards each other, the support plates and the main shaft assembly enclose folding space for accommodating a flexible display of the mobile terminal in a folded state, so that the bending effect of the flexible display is improved, and two housings of the mobile terminal fit almost seamlessly in the folded state.

Abstract: A hinge mechanism and a foldable electronic device are provided. The hinge mechanism is disposed in a foldable electronic device. When one rotation portion of the foldable electronic device moves, the hinge mechanism drives the other rotation portion to move. The hinge mechanism includes a fastening support, a transmission assembly, two first transmission shafts, a clamping assembly, and a first elastic portion. The fastening support is configured to be fastened to a base of the foldable electronic device, and the fastening support is coupled to the first transmission shaft to limit relative positions of the first transmission shaft and the fastening support. The first transmission shaft is coupled to the clamping assembly and the first elastic portion. The first elastic portion provides an elastic force for the clamping assembly such that friction between the clamping assembly and the transmission assembly generates damping.

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: The hinge mechanism includes a base, a first rotation assembly, a second rotation assembly, and a damping assembly. The damping assembly includes an elastic module and an even number of friction assemblies. Each friction assembly includes an intermediate shaft and a gear member. The intermediate shaft includes a shaft body and a mounting part. The shaft body is connected to the base. The mounting part is disposed on the shaft body. The mounting part has a tapered groove. The gear member includes an insertion part. The insertion part has a tapered face, and the insertion part is inserted into the tapered groove. The tapered face abuts against a groove face of the tapered groove under an action of elastic force of the elastic module. A first swing arm of the first rotation assembly and a second swing arm of the second rotation group rotate around the base.

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 connection rod and a swing arm are separately rotatably connected to a primary shaft component, and an axis around which the swing arm rotates and an axis around which the connection rod rotates are different, so that the swing arm and the connection rod rotate and slide relative to each other. The swing arm or the connection rod drives a support plate to rotate, so that the primary shaft component and the support plates can encircle to form, when the mobile terminal is completely folded, space that accommodates a folded part of a flexible display.
