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 rotation shaft structure includes a main shaft assembly, and two folding assemblies that are symmetrically disposed with respect to the main shaft assembly. The two folding assemblies may rotate toward or against each other relative to the main shaft assembly. When the folding assembly is specifically disposed, 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.

Abstract: A rotating shaft mechanism (1) includes a length maintaining mechanism (1a) and a main shaft assembly (1b). The length maintaining mechanism (1a) includes a fastening member (101) and two swing arms (102, 103), and the two swing arms (102, 103) are rotatably connected to the fastening member (101). The swing arm includes a sliding block (1021), a swing rod (1022), and a connecting assembly (1023), and the swing rod (1022) may slide along the sliding block (1021). The swing rod (1022) is rotatably connected to the fastening member (101), and the connecting assembly (1023) is also rotatably connected to the fastening member (101). When the swing rod (1022) rotates relative to the fastening member (101), the connecting assembly (1023) may be driven to rotate around the fastening member (101). The main shaft assembly (1b) includes a cover plate (105).

Abstract: Embodiments provide a hinge mechanism and a foldable mobile terminal. A swing arm component and a synchronization component are disposed on both sides of a main shaft component of the hinge mechanism, so that when a swing arm rotates around the main shaft component, a synchronization arm on a same side as the swing arm rotates accordingly to drive a synchronization arm and a swing arm on the other side to rotate, and further, housings on both sides of the foldable mobile terminal including the main shaft component can move synchronously, and force of a flexible screen is relatively even. In addition, because swing arms on both sides of the main shaft component rotate around different axes, through such a design, accommodation space that can accommodate the flexible screen can be formed during rotation of the swing arms, so that damage to the flexible screen is reduced.

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.
