Abstract: A hinge mechanism includes a base and two rotating components. Each rotating component includes a support arm, a swing arm, and a housing mounting bracket. The two support arms are respectively disposed on two sides of the base and are rotatably connected to the base. The two swing arms are respectively disposed on two sides of the base and are rotatably connected to the base. Each of the two housing mounting bracket is provided with two sliding grooves. For a support arm, a swing arm, and a housing mounting bracket that are located on a same side of the base, the support arm and the swing arm may separately slide in a sliding groove, and projections of sliding directions of the support arm and the swing arm are not parallel in a reference plane perpendicular to the rotation axes of the support arm and the 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 foldable electronic device and a hinge mechanism thereof are provided. In addition to the hinge mechanism, the electronic device further includes two housings and a flexible display. The two housings are respectively disposed on two opposite sides of the hinge mechanism and are rotatably connected to the hinge mechanism. The hinge mechanism includes a base and a main shaft module. The base includes a bearing surface. The main shaft module includes two rotating assemblies. The two rotating assemblies are disposed on two opposite sides of the base. Each rotating assembly includes a swing arm and a housing fastening bracket, and each housing fastening bracket may be fastened to a housing on a corresponding side. In an unfolded state, the bearing surface independently supports a foldable portion of the flexible display. In a folded state, a screen accommodation space is formed between the two housing fastening brackets and the base.

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 and a main hinge module. The base includes a support surface for supporting a flexible display. The main hinge module includes a first rotating component and a second rotating component disposed on two opposite sides of the base. The first rotating component includes a first support plate, and the first support plate includes a first plate surface for supporting the flexible display. The second rotating component includes a second support plate, and the second support plate includes a second plate surface for supporting the flexible display. When the hinge mechanism is in a folded state, an included angle between the first plate surface and a bearing surface is less than an included angle between the second plate surface and the bearing surface, to form display accommodating space between the first plate surface, the second plate surface, and the bearing surface.

Abstract: A foldable module is provided, including a first connection part, a first pin, a first drive ring, and a first spring. A first pin hole is disposed on the first connection part, and the first pin passes through the first drive ring, the first pin hole, 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, and the first convex part is located between the first spring and the first concave part, or the first concave part is located between the first spring and the first convex part. When the first connection part rotates, the first convex part slides out of the first concave part. 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.
