Description

Technical Field

[0001] The utility model relates to the field of automobile panoramic sunroofs, in particular to a composite glass applied to automobile panoramic sunroofs. Background Art

[0002] As people's demand for the comfort and practicality of cars continues to increase, the functions of cars are also increasing. Among them, the panoramic sunroof has become one of the necessary equipment for modern cars, which can provide an unobstructed ultra-large field of view, excellent lighting effect, and create a wonderful driving experience. For example, the panoramic sunroof of Model Y has a whole glass area of ​​1.7 square meters. In addition to the wide field of lighting, it also performs well in rigidity, blocking ultraviolet rays, quiet sound insulation, etc. There are many advantages of the panoramic sunroof, but the disadvantages are also obvious. Direct sunlight causes the temperature in the car to rise rapidly. Even the Tesla modelY panoramic sunroof that can block 95% of infrared rays, in Seattle summer, exposed to the sun for 1 hour, the inner and outer surfaces of the sunroof exceeded 55°C, and exposed to the sun for 2 hours, it reached more than 70 degrees, and the feeling of being roasted on the head was very obvious.

[0003] Therefore, there is an urgent need in the market for a transparent cool glass that can maintain a low temperature and is not hot to the touch even under exposure to the sun. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a composite glass applied to a panoramic sunroof of an automobile, the composite glass having the characteristics of safety, heat insulation, sound insulation, energy saving, color change, transparency and the like.

[0005] The utility model provides a composite glass applied to a panoramic sunroof of an automobile. The composite glass comprises an upper sunroof glass and a lower double-curvature organic glass. The edges of the upper and lower layers are bonded by a sealant.

[0006] The curvature of the double-curvature organic glass is required to be greater than 1000 and less than 20000; the normal chord height is 2-30mm; and the horizontal chord height is 2-200mm.

[0007] The size range of the double-curvature organic glass is: length: 50-180cm; width: 40-150cm. The curved surface of the skylight glass and the double-curvature organic glass is consistent.

[0008] The size and curvature of the double-curvature organic glass are precisely controlled by vacuum forming, hot bending or molding.

[0009] The double curvature organic glass has a heat insulation function. Furthermore, its heat insulation performance can be further enhanced by adding heat insulation nanoparticles or applying a heat insulation coating.

[0010] The double curvature organic glass can be endowed with a color changing function by adding thermochromic nanoparticles. The gap between the upper layer and the lower layer is filled with an aluminum strip.

[0011] The gap between the upper layer and the lower layer is filled with air, nitrogen or argon.

[0012] Beneficial Effects

[0013] Due to the adoption of the above-mentioned technical scheme, compared with the prior art, the utility model has the following advantages and positive effects: the utility model adopts hyperbolic plexiglass, which has excellent heat insulation, and can still maintain a low temperature and cool feeling under exposure to the sun, and is not hot to the touch; it is heat-insulating and heat-preserving, and has obvious energy-saving effects; when the temperature reaches 45°C, it automatically reduces the light transmittance, increases the haze, and blocks heat transfer; the utility model also fills gas in the gap to maintain structural stability and enhance the heat insulation and sound insulation effects; the utility model has the characteristics of safety, heat insulation, sound insulation, energy saving, color change, transparency, etc. The most distinctive feature is that even under high temperature exposure, the inner surface temperature of the skylight remains below 50°C, is not hot to the touch, and reduces the feeling of roasting, and has good market application prospects.
