canopy is movably installed at the bottom of the baffle through a linear driving piece; the movable area of the terrace is shielded through the baffle, the electric push rod is started to drive the inner-layer glass to move up and down to achieve vertical window sealing, meanwhile, the glass
canopy is driven to be unfolded to rise with the inner-layer glass, and the glass
canopy finally makes contact with the inner-layer glass, so that a
closed space is formed in the terrace area, and the terrace sealing function is achieved; and external
