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.

The utility model relates to the field of evaporation coating, in particular to an evaporation coating device, which comprises an evaporation coating unit, a vacuum chamber and an evaporation coating unit, the evaporation coating unit enables evaporation substances evaporated from an evaporation coating source to be subjected to evaporation coating on a base film, and the vacuum chamber is used for setting a space for arranging the evaporation coating source and the base film and can keep the space in a vacuum state. And the laser evaporation unit is positioned in the vacuum chamber and is used for emitting high-power laser to evaporate the evaporation coating source. According to the device, a high-power laser beam is emitted through a laser emitter and is aligned with the surface of an evaporation coating source on a tray to perform scanning type irradiation, the surface layer of the evaporation coating source is evaporated through the laser beam, and an evaporation substance is deposited on the surface of a base film to form a thin film. According to the evaporation mode, resistance heating is not needed, splashing generated by corrosion of a resistance material and mixing of molten aluminum is reduced, poor products generated by resistance fluctuation in long-time production are reduced, and the yield of the products is greatly increased.

The invention relates to a method of using a thermal laser evaporation (TLE) system. The TLE system comprising a reaction chamber fillable with a reaction atmosphere, a substrate arranged in the reaction chamber, and one or more sources arranged in the reaction chamber. Each source comprising a source element including a source material, and a laser source for providing a laser beam impinging on the source element and thereby evaporating or sublimating the source material for providing a flux of evaporated or sublimated source material for a deposition onto the substrate.

The invention relates to a beam line for a laser beam of a thermal laser evaporation (TLE) system. The beam line extends between a source end of the beam line and a chamber end of the beam line. The source end is connectable to a laser source and the chamber end is connectable to a reaction chamber of the TLE system.
