In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

an automotive sunroof assembly comprising:

the skylight glass comprises a first layer of glass, a first adhesive layer, a light adjusting film, a second adhesive layer and a second layer of glass which are sequentially stacked; patterns are etched on the surface of the light adjusting film;

the control device is used for controlling the power-on or power-off of the light adjusting film so as to adjust the visible light transmittance of the skylight glass;

a light source configured to be capable of irradiating the light adjusting film when the visible light transmittance of the sunroof glass decreases.

Preferably, the light adjusting film is separated to form at least two etching areas, and the surface of each etching area is etched with the pattern; the control device can individually control each etching area to be powered on or powered off.

Preferably, the skylight glass further comprises a PET film, wherein the PET film is positioned between the first adhesive layer and the light adjusting film; the surface of the PET film is provided with a plurality of spherical bumps, and the patterns show a three-dimensional effect when the skylight glass is observed through the spherical bumps.

The invention has the beneficial effects that:

the invention discloses an automobile skylight assembly which comprises skylight glass, a control device and a light source. A pattern is etched on the surface of the light adjusting film. The pattern formed by the surrounding of the miniature etching lines is invisible, and the control device controls the power-off or power-on of the light adjusting film so as to adjust the visible light transmittance of the skylight glass. When the visible light transmittance of the sun glass is reduced, the light adjusting film forms a rear projection plate, the light source irradiates the light adjusting film, and the etched lines can reflect light, so that the pattern is displayed, and an atmosphere lamp effect is created. Compared with the third layer of glass printed with visible patterns additionally arranged in the skylight glass, the skylight glass in the automobile skylight assembly does not need to be additionally provided with the third layer of glass, the total weight and the cost of the skylight glass are reduced, and the skylight glass is convenient to install. Meanwhile, the pattern on the light adjusting film is invisible without being irradiated by a light source. When the visible light transmittance of the light adjusting film is increased, the skylight glass has good light transmittance.

The automobile comprises the automobile skylight assembly. The skylight glass in the automobile skylight assembly does not need to be additionally provided with a third layer of glass, so that the total weight and the cost of the skylight glass are reduced, and the skylight glass is convenient to install. Meanwhile, when the visible light transmittance of the light adjusting film rises, the skylight glass has good light transmittance, and the driving and riding experience of the automobile is improved.
