As shown in fig. 1 to 5, the utility model provides a laminated glass for automobiles, including outer integrated configuration and inlayer glass substrate 6, be provided with between outer integrated configuration and the inlayer glass substrate 6 and be used for the air bed that separates both, outer integrated configuration is including the first outer glass substrate 7 that sets gradually, first cover layer 8, heating resistor layer 9, diaphragm layer 10 and the outer glass substrate 11 of second, diaphragm layer 10 and first outer glass substrate 7 and the outer glass substrate 11 adhesive bonding of second.

Specifically, as shown in fig. 1 to 5, the second outer glass substrate 11 is positioned between the first outer glass substrate 7 and the inner glass substrate 6, and the inner glass substrate 6 faces the cab after being mounted on the vehicle. The first outer glass substrate 7, the second outer glass substrate 11 and the inner glass substrate 6 are glass sheets having the same curvature, and preferably, the glass sheets are float glass having a thickness of 1.8mm to 3.5 mm.

As shown in fig. 5, preferably, the material of the first capping layer 8 is ceramic, and the first capping layer 8 is coated on the first outer glass substrate 7 by using a transfer printing process.

The heating resistance layer 9 is uniformly arranged on the film layer 10 in a rolling mode, and the glass can be heated after the heating resistance layer 9 is electrified. In order to improve the heating uniformity, the heating resistance layer 9 adopts a wave-shaped design, and the length of the tungsten filament is increased. The metal tungsten wire is used as a heating resistor and is an extremely thin metal wire which can be seen only in a short distance without influencing the sight of a driver. The roller is adopted for wire distribution, the wire distribution length is increased through the wavy design, the resistance of the roller is more uniform and stable, and bus bars are arranged on two sides of the roller and are used as power supply leads. In order to make the work more stable, a segmented resistor series-parallel combination design is adopted. The metal tungsten wire has a heating function, and is heated after being electrified, so that the phenomenon of fogging caused by temperature difference in a vehicle can be avoided, the surface temperature of glass can be increased, and accumulated snow is melted.

The polyvinyl butyral film is a colorless and odorless chemical material and has strong bonding capability, and the film layer 10 tightly bonds the first outer layer glass substrate 7 and the second outer layer glass substrate 11 together. Under the adhesion, the layers can be closely adhered into a whole, and then the effects of heat insulation, low transmittance, ultraviolet resistance and the like are finally realized through the polymerization action of high temperature and high pressure by a special process.

Preferably, the thickness of the membrane layer 10 is 1520-3040 μm, and the membrane layer 10 is a uniform multi-layer substrate.

As shown in fig. 1 to 4, a second capping layer 12 is disposed on the inner glass substrate 6, and the second capping layer 12 is made of ceramic. The second cover layer 12 is coated on the inner surface of the inner glass substrate 6 using a transfer printing process. A temperature control box 4 is pasted on the inner layer glass substrate 6, and the temperature control box 4 is used for measuring the temperature of the surface of the glass and controlling the heating system.

As shown in fig. 1 to 4, in order to achieve a better sound insulation effect, the outer layer composite structure and the inner layer glass substrate 6 are separated by an air layer, the edge portion is separated by a separation aluminum strip 14, the separation aluminum strip 14 is filled with a drying agent 13 to prevent the inner air in the air layer from being wet to cause glass fogging, the separation aluminum strip 14 is bonded and connected with the second outer layer glass substrate 11 and the inner layer glass substrate 6 by an adhesive 15, and the adhesive 15 is preferably butyl rubber. The outer edges of the spacer aluminium strips 14 are sealed with a polysulphide glue 16, the polysulphide glue 16 being located between the second outer glass substrate plate 11 and the inner glass substrate plate 6. Meanwhile, the outer layer composite structure is larger than the inner layer glass substrate 6 according to the design size, and enough size is reserved for facilitating the installation and positioning of the glass on the automobile frame.

Meanwhile, a positioning mark for installing the camera in the vehicle is arranged on the printed pattern, so that the installation of a support cover plate of the camera is facilitated.

As shown in fig. 1 to 5, the temperature control box 4 is adhered to the inner glass substrate 6, and can monitor the temperature of the glass surface in real time. When the surface temperature of the glass exceeds a set value during the use of the automobile, a power supply signal for controlling a heating system is cut off, and the heating resistor layer 9 stops heating. On the contrary, when the temperature of the glass surface is lower than the lower limit of the set value, the circuit is switched on to supply power to the heating resistance layer 9, the heating resistance layer 9 heats, the temperature of the glass surface is improved, a heating system does not need to be manually controlled, and automatic control is achieved.

Preferably, the air layer is filled with an inert gas to improve the sound insulation effect. The sandwich glass with the hollow structure has good effects of preventing heat dissipation and sound insulation in the vehicle, and improves the use comfort of customers.

In the laminated glass for the automobile with the structure, the intermediate layer is arranged between the first outer layer glass substrate 7 and the second outer layer glass substrate 11 and is formed by combining the heating resistance layer 9 and the diaphragm layer 10, so that the function of adhering the first outer layer glass substrate 7 and the second outer layer glass substrate 11 is achieved, and an outer layer combined structure is formed.
