A sunroof glass for adjusting the atmosphere in the car

Abstract

The invention relates to skylight glass for adjusting the atmosphere in a vehicle, which comprises a first glass plate, an adhesive layer, a flexible sheet body layer and a second glass plate which are sequentially laminated from top to bottom, a light source is arranged at the side edge of the second glass plate, the refractive index of the second glass plate is larger than that of the flexible sheet body layer, the lower surface of the flexible sheet body layer is provided with a reflecting pattern, the boundary of the flexible sheet body layer is contracted inwards by 3-30mm relative to theboundary of the second glass plate, the adhesive layer and the second glass plate are jointly sealed and coated with the flexible sheet body layer, and the lower surface of the flexible sheet body layer is tightly attached to the upper surface of the second glass plate. The reflecting pattern is directly made on the flexible sheet body layer, so that the reflecting pattern can be better attachedto the glass model with a small curvature and a large arch height, the lower surface of the flexible sheet body layer is tightly attached to the upper surface of the second glass plate, the reflectingpattern is directly contacted with the upper surface of the second glass plate, therefore, the formed planar light source has obvious luminous effect and can create good in-vehicle atmosphere.

Description

Technical field: [0001] The invention relates to the technical field of skylight glass, in particular to a skylight glass for adjusting the atmosphere in a car. Background technique: [0002] As people's requirements for driving experience continue to increase, the interior ambient light technology that can improve the driver's mood has gradually developed. Among them, the car sunroof integrated with ambient light technology has been widely used in mid-to-high-end vehicles due to its unique lighting and decorative effects. In the vehicle sunroof of the model. [0003] For example, Chinese patent CN103770696B discloses a vehicle glazing, including a light source, a glass plate, a refraction layer and a light guide layer. The edge of the light guide layer can be fully or partially structured by mechanical structuring, embossing, corrosion or spraying techniques to produce reflective patterns, making the car more gorgeous at night, and can play a role in setting off the atmosp...

Problems solved by technology

But the scattering layer is not made on the inner surface of the second transparent plate, the light needs to pass through the second transparent adhesive layer, and then enter the second transparent adhesive layer before reflecting on the printed pattern, which must ensure that the printed pattern and the second transparent The second transparent adhesive layer between the two transparent plates must have the same refractive index as the second transparent plate to form the effect of a planar light source, but it is difficult to obtain materials with the same refractive index as the second transparent plate in actual production; in addition When the light passes through the second transparent plate, it will produce a certain reflection, and the intensity will be attenuated. However, the light intensity entering the second transparent adhesive layer is limited. Also, the light reflected by the pattern will be weaker, so the light reflected by the pattern will be light-guided Covered by the light emitted by the layer, the luminous effect of the formed surface light source is not ideal, and the ambience effect created in the car cannot meet people's needs.
