The invention discloses a vacuum structure folding door which comprises a first connecting shaft, a second connecting shaft, at least two door hinges and a sliding rail. The door hinges are rotationally hinged to the first connecting shaft and swing freely with the first connecting shaft as the joint. Each door hinge is a geometric cylinder defined by at least four circular arc pieces, wherein a cavity is formed in the middle of the door hinge. The circular arc pieces are connected with one another with the second connecting shaft as the joint. The circular arc pieces are rotationally hinged to the joint to fold and stretch around the joint so that the door hinges can stretch and contract. The peripheries of the cavities are closed and are pumped to be in a vacuum state. According to the vacuum structure folding door, at least four circular arc pieces are rotationally hinged to the connecting shaft to form each door hinge with the cavity formed in the middle, and therefore the sound absorbing and heat insulating functions of the door hinges are improved; the cavities are pumped to be in the vacuum state to prevent transmission of sounds and heat, and therefore sound and heat insulation is more thorough.
