Abstract: This application provides a rotary mechanism, a support apparatus, and an electronic device, and relates to the field of electronic device technologies, allowing the electronic device to be lighter and thinner in an unfolded state. The rotary mechanism includes a base, a first connector, a second connector, a lifting plate, a first torsion spring, and a second torsion spring. The first connector and the second connector are rotatably connected to the base by a first rotary shaft and a second rotary shaft respectively. The first torsion spring includes a first spiral body and a first torsion arm. The first spiral body is sleeved on the first rotary shaft. One end of the first torsion arm is fixed to one end of the first spiral body. An other end of the first torsion arm is slidably connected to the lifting plate in a first direction. The second torsion spring includes a second spiral body and a second torsion arm. The second spiral body is sleeved on the second rotary shaft. One end of the second torsion arm is fixed to one end of the second spiral body. An other end of the second torsion arm is slidably connected to the lifting plate in the first direction. The rotary mechanism provided in embodiments of this application is used for supporting a bending portion of the foldable screen.

Abstract: Embodiments of this application disclose a folding mechanism and a mobile terminal. The folding mechanism includes a bracket and two support assemblies, with the two support assemblies respectively located on two sides of the bracket in a width direction. The support assembly includes a first support, a second support, and a swing arm, with the second support and the swing arm located on a same side of the first support. Because the second support and the first support are slidably connected rather than pivotally connected, the second support and the first support can be considered as one telescopic rod as a whole. Therefore, the bracket, the second support, the first support, and the swing arm form an equivalent three-rod linkage mechanism. In comparison with the related art, one linkage rod is saved, shortening a tolerance chain, which helps reducing a total tolerance of the folding mechanism.

Abstract: A rotating mechanism, a supporting apparatus, and an electronic device are provided. The rotating mechanism includes a base, a first connecting piece, a second connecting piece, a lifting plate, a force applying structure, and a supporting structure. The first connecting piece and the second connecting piece are both rotatably connected to the base; and when the first connecting piece and the second connecting piece are in an unfolding position, the force applying structure applies, to the lifting plate, a tensile force from the lifting plate to a side of the lifting plate away from a fitting surface, and the supporting structure applies, to the lifting plate, a first supporting force that counterbalances the tensile force.
