1. A folding device comprising:
a bearing and fixing mechanism configured to bear and fix a main body portion of a to-be-folded device;
a folding mechanism disposed on at least one lateral side of the bearing and fixing mechanism, the folding mechanism being configured to bear a to-be-folded portion of the to-be-folded device and fold the to-be-folded portion to one side in a thickness direction of the main body portion;
a first driving mechanism connected to the folding mechanism and configured to drive the folding mechanism to move along a direction perpendicular to a bearing surface, which bears the main body portion, of the bearing and fixing mechanism; and
a second driving mechanism connected to the folding mechanism and configured to drive the folding mechanism to move close to or away from the bearing and fixing mechanism along a direction parallel to the bearing surface,
wherein the folding mechanism comprises:
a first bearing stage; and
a first rotating shaft disposed on a side of the first bearing stage facing toward the bearing and fixing mechanism, the first rotating shaft comprising a rotating shaft body and a flexible layer disposed around the rotating shaft body, the rotating shaft body being rotatably connected to the first bearing stage.
