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: 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: A rotating shaft mechanism (1) includes a main shaft module (101), and the main shaft module (101) includes a base (1013), a first support plate (1011), a second support plate (1012), a first gear linkage (1014), a second gear linkage (1015), an elastic mechanical part (1022), and a conjoined cam (1021). The first support plate (1011) and the second support plate (1012) are rotatably connected to the base (1013). The first gear linkage (1014) and the second gear linkage (1015) are rotatably connected to an end portion of the base (1013), and the first gear linkage (1014) and the second gear linkage (1015) are connected through transmission by using gears that are engaged with each other.

Abstract: Provided herein is a keyboard assembly that includes a keyboard substrate, a plurality of keycaps, and a plurality of lifting supports. Each keycap is connected to the keyboard substrate by using a lifting support. The keyboard substrate is connected to a bottom plate and a top plate, with the bottom plate including a key accommodation groove that further includes a concave slope. The lifting support is located in the key accommodation groove, with one end abutting against the concave slope and being capable of sliding on the concave slope. In a process in which the top plate rotates to a first specified location, the keyboard substrate is driven to move, the lifting support descends, and the keycap descends. In a process in which the top plate rotates to a second specified location, the keyboard substrate is driven to move.
