Abstract: A middle frame assembly and a display device. The middle frame assembly includes a rotating shaft component, a first middle frame body, a first sliding middle frame, and a first transmission component. The first transmission component includes a first driving bevel gear, a second driving bevel gear, a first driven bevel gear, and a transmission part. The first driving bevel gear and the second driving bevel gear can rotate in a first axial direction under the action of rotation of the first middle frame body relative to the rotating shaft component. A circumference of a pitch circle of the second driving bevel gear is greater than that of the first driving bevel gear. The first driven bevel gear is configured to mesh with the first driving bevel gear in a first state and with the second driving bevel gear in a second state.

Abstract: The present disclosure discloses a folding mechanism and a display device. The folding device includes a supporting plate, a lifting plate, at least one rotatable plate, a transmission assembly, a first elastic member, and at least one pushing wheel. The supporting plate has a first surface and a second surface. The lifting plate is arranged on a side of the first surface away from the second surface. The first elastic member is provided between the lifting plate and the supporting plate. The pushing wheel is connected with the rotatable plate through the transmission assembly. Rotating of the rotatable plate from the folding position to the unfolding position causes the pushing wheel to push the lifting plate to a supporting position, and during rotating of the rotatable plate from the unfolding position to the folding position, the first elastic member enables the lifting plate to move to an avoidance position.
