Foldable mechanism and mobile terminal

A foldable mechanism, comprising a base assembly, two support assemblies, and two driving assemblies, wherein

• the base assembly comprises a bottom seat and two hinge seats, and the two hinge seats are respectively fixed to two sides of the bottom seat;
• the two support assemblies are respectively located at two sides of a central axis of the bottom seat, the support assembly comprises an outer plate member and an inner plate member, the two inner plate members are located between the two outer plate members, the outer plate member and the inner plate member are pivotally connected to the corresponding hinge seat respectively, and pivotal axes of the outer plate members and the inner plate members are parallel to the central axis of the bottom seat;
• the two driving assemblies are respectively located at the two sides of the central axis of the bottom seat, and the driving assembly is connected to and between the bottom seat and the inner plate member corresponding to the driving assembly;
• and
• in a case that the foldable mechanism is in a folded state, the driving assemblies respectively drive the corresponding inner plate members to flip toward the bottom seat, to form a concave space for accommodating a bending part of a flexible screen at an angle between the two inner plate members.
