    Abstract: Embodiments of this application provide a foldable-screen device and a hinge component. An elastic component is disposed on a support member, a first end of the elastic component presses against a primary shaft mechanism when a rotation mechanism rotates to a flattened state, a second end of the elastic component is connected to the support member, and the elastic component is in a compressed state when the rotation mechanism rotates to the flattened state, so that the elastic component generates a spring force, the second end of the elastic component can drive the support member to move far away from the primary shaft mechanism when a user releases or reduces an active force applied to a framing member on one side of the support member in a flattened direction, and a flexible screen is flattened in a direction far away from the primary shaft mechanism under driving of the support member and the framing member. This avoids a case in which the flexible screen is arched at a joint between the rotation mechanism and the primary shaft mechanism when the hinge component is in a flattened state, ensures flatness of the flexible screen of the foldable-screen device in a flattened state, improves display performance of the foldable-screen device, and also improves a lifespan of the flexible screen.

    Abstract: A folding apparatus and an electronic device are disclosed. The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state. Therefore, when the electronic device is unfolded from the folded state to the flattened state, layered misalignment of the flexible display can be reduced, and crease recovery of the flexible display can be accelerated, thereby improving a flattening effect of the flexible display.

The folding apparatus (100) includes a first housing (10), a rotation mechanism (20) and a second housing (30). The rotation mechanism (20) includes a middle housing (1), a first support (2) and a second support (3), one end of the first support (2) is rotatably connected to the middle housing (1), and the other end is fixedly connected to the first housing (10). A support surface (21) of the first support (2) is spliced with a support surface (102) of the first housing (10) to form a first support surface (401). One end of the second support (3) is rotatably connected to the middle housing (1), and the other end is fixedly connected to the second housing (30). A support surface (31) of the second support (3) is spliced with a support surface (302) of the second housing (30) to form a second support surface (402). When the first housing (10) and the second housing (30) are folded relative to each other to a closed state, the first support (2) and the second support (3) are far away from each other, and the first support surface (401) and the second support surface (402) gradually approach each other in a direction away from the middle housing (1). A main moving mechanism of the rotation mechanism (20) of the folding apparatus (100) has a small quantity of parts, so that control precision is high.
