Foldable-screen device and hinge component

A foldable-screen device, comprising a flexible screen, two framing members, and a hinge component located between the two framing members, wherein:

• the flexible screen is located on a surface of a same side of the two framing members and the hinge component;
• the hinge component comprises a primary shaft mechanism and two rotation mechanisms that are located on two sides of the primary shaft mechanism and that are rotatably connected to the primary shaft mechanism, wherein each rotation mechanism comprises a support member, a first end of the support member is rotatable around the primary shaft mechanism, a second end of the support member is connected to a corresponding framing member, and a part of the flexible screen is connected to a surface of one side of the support member;
• and
• an elastic component is further disposed on the support member, a first end of the elastic component presses against the primary shaft mechanism when the rotation mechanism rotates to a flattened state, a second end of the elastic component is connected to the support member, and a compression rate of the elastic component when the rotation mechanism rotates to the flattened state is greater than a compression rate of the elastic component when the rotation mechanism rotates to a folded state.
