The technology of this application relates to a foldable mobile terminal. The foldable mobile terminal includes a rotating shaft mechanism, two housings, and a flexible display. The flexible display is embedded into the two housings and covers the rotating shaft mechanism. The rotating shaft mechanism has a main shaft and two rotation parts, and the rotation part rotates with the housing on a corresponding side. The flexible display is fixed to the two housings and the two rotation parts. In this way, in a folding or unfolding process of the foldable mobile terminal, relative sliding of the flexible display relative to the two housings and the rotation parts can be avoided, thereby reducing a risk of damaging the flexible display. In addition, a part of the flexible display that is opposite to the main shaft can be bent freely.

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.

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.
