This invention provides an intelligent dimming laminated vacuum composite roof
glass structure and its manufacturing method, comprising an outer tempered or semi-tempered glass, a film layer, an EC-coated glass, an edge sealing layer, and an inner vacuum glass layer, stacked sequentially from the outside of the roof to the inside of the vehicle. The EC-coated glass and the inner vacuum glass are edge-sealed by the edge sealing layer to form an EC-coated insulated
glass structure. Then, a
getter is activated by
laser evaporation to adsorb air from the insulated
glass structure, forming an EC-coated vacuum glass structure. The film layer is then laminated and fixed to the outer tempered or semi-tempered glass to form a laminated vacuum
composite structure. Multiple vacuum support pillars are provided on the side of the inner vacuum glass facing the EC-coated glass to form and maintain the vacuum cavity. This invention uses vacuum glass to isolate external heat conduction, combined with the active modulation of visible light and
infrared radiation by the EC-coated glass, to achieve intelligent temperature regulation, significantly improving driving comfort.
