Abstract: The hinge mechanism includes a base and a main hinge module. The base includes a support surface for supporting a flexible display. The main hinge module includes a first rotating component and a second rotating component disposed on two opposite sides of the base. The first rotating component includes a first support plate, and the first support plate includes a first plate surface for supporting the flexible display. The second rotating component includes a second support plate, and the second support plate includes a second plate surface for supporting the flexible display. When the hinge mechanism is in a folded state, an included angle between the first plate surface and a bearing surface is less than an included angle between the second plate surface and the bearing surface, to form display accommodating space between the first plate surface, the second plate surface, and the bearing surface.

Abstract: A foldable assembly which is configured to bear a flexible display. The foldable assembly includes a rotating shaft; a first mechanical part and a second mechanical part, where the first mechanical part and the second mechanical part are rotatably connected by using the rotating shaft; and a first protective structure, where the first protective structure is connected to an end face that is of the rotating shaft and that extends out of a periphery of the flexible display. A first surface of the flexible display is away from the rotating shaft, and the first protective structure is higher than or flush with the first surface of the flexible display, so that when the foldable display terminal falls, the first protective structure is in contact with a point of collision earlier than the flexible display.
