Foldable device

A foldable device, comprising:

• a housing assembly comprising a first mechanical part, a second mechanical part, a third mechanical part, a first hinge mechanism, and a second hinge mechanism;
• and
• a flexible display, disposed on a surface of the housing assembly, comprising a support layer and a cover layer, wherein the support layer is located on a side, facing the housing assembly, of the flexible display, and the cover layer is located on a side, facing away from the housing assembly (10), of the flexible display;
• wherein the first mechanical part comprises a first end and a second end opposite to each other, the first end is rotatably connected to the second mechanical part through the first hinge mechanism, and the second end is rotatably connected to the third mechanical part through the second hinge mechanism;
• the first mechanical part comprises a first side surface and a second side surface, the first side surface and the second side surface are separately located on two sides in a thickness direction of the first mechanical part, and when the foldable device is in a folded state, the second mechanical part is located on a side in a second direction of the first mechanical part, and the third mechanical part is located on a side in a first direction of the first mechanical part, wherein the first direction is a direction in which the first side surface faces the flexible display along the thickness direction of the first mechanical part, and the second direction is a direction in which the second side surface faces away from the flexible display along the thickness direction of the first mechanical part;
• and
• one of the support layer and the cover layer is fastened to the first side surface, the second mechanical part, and the third mechanical part.
