The specific implementation mode is as follows:

to explain technical contents, achieved objects and effects of the present invention in detail, the present invention will be further described with reference to the accompanying drawings and embodiments, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

In the present invention, the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. These terms are primarily intended to better describe the utility model and its embodiments, and are not intended to limit the indicated devices, elements or components to a particular orientation, and therefore should not be construed as limiting the utility model.

As shown in fig. 1, in an exemplary embodiment, the present invention provides a dimmable skylight front stop two-in-one functional glass, which includes a first light-transmitting plate 1, a second light-transmitting plate 6, and a dimming film sheet 3 located between the first light-transmitting plate 1 and the second light-transmitting plate 6, and is characterized in that the dimmable skylight front stop two-in-one functional glass can be divided into a skylight area S1 and a front stop area S2, the dimming film sheet 3 covers the skylight area S1, in the skylight area S1, the dimming film sheet 3 is bonded to the first light-transmitting plate 1 through a first adhesive layer 2, and is bonded to the second light-transmitting plate 6 through a second adhesive layer 4, and in the front stop area S2, the first light-transmitting plate 1 is bonded to the second light-transmitting plate 6 through a front stop adhesive layer 5.

The first light-transmitting plate 1 and the second light-transmitting plate 5 in the utility model are preferably made of conventional glass, and can be made of single piece of common glass or toughened glass, can also be made of laminated glass, and can also be made of organic glass, and the first light-transmitting plate 1 and the second light-transmitting plate 5 are preferably made of single piece in consideration of the weight of an automobile. The first transparent plate 1 and the second transparent plate 5 are preferably made of curved glass, curved functional laminated glass suitable for automobiles can be obtained when the curved glass is used, and at the moment, other laminated layers between the first transparent plate 1 and the second transparent plate 5 are also curved with corresponding curvatures. It will be appreciated that any conventional light-transmitting material is suitable for use in the present invention, and that changes in the material of the light-transmitting panel do not substantially affect the implementation of the present solution. In one embodiment, at least one of the first and second

transparent plates

1 and 5 is made of a dark transparent material in the area of the louver area S1, and the transmittance of the transparent plate using the dark transparent material is less than 20%, and the transparent plate is generally black or gray in color, so as to reduce the overall transmittance in the louver area S1.

The two-in-one functional glass integrates the front windshield and the skylight glass into a whole, and the original metal plate between the front windshield and the skylight glass is not needed, so that the appearance integrity and the vehicle safety are improved. The two-in-one function is visually distinguished by dividing it into a sunroof region S1 and a front windshield region S2. The skylight area S1 of the two-in-one functional glass is provided with the light adjusting film 3, the purpose of shading sun can be realized by controlling the light adjusting film 3, and the front blocking area S2 usually has enough light transmittance to ensure the visual field during driving.

In one embodiment, the front adhesive layer 5 has a transition shade strip 7 at a portion near the skylight area S1, that is, the front adhesive layer 5 has a dark portion with a certain width at an edge near the skylight area S1 as the transition shade strip 7 for blocking the upper light affecting the sight line when driving. It will be appreciated that the transition shade strip 7 may also be a separate adhesive segment, embedded tightly between the windshield adhesive layer 5 and the material in the skylight area S1.

The bonding layer, namely the transitional sunshade belt 7, is made of materials, such as PVB or EVA, commonly used for laminated glass in the automobile industry, is usually transparent and has extremely high light transmittance, and also can be made of dark materials with certain light absorbance according to needs, and the transmittance is low, for example, the transitional sunshade belt 7 in the utility model needs to be made of dark materials to achieve the purpose of absorbing light and shading.

In another embodiment, the first light-transmitting panel 1 has a printed sunshade tape 8 at the junction of the skylight area S1 and the front stop area S2, and the printed sunshade tape 8 also serves to shade the upper light rays affecting the sight line during driving. By adopting the embodiment, the special adhesive material does not need to be changed, the printing process is mature and simple, and the production efficiency is high.

Wherein the thickness of the front barrier bonding layer 5 is larger than the sum of the thicknesses of the first bonding layer 2 and the second bonding layer 4. Because the light adjusting film 3 is arranged between the first bonding layer 2 and the second bonding layer 4, in order to keep the whole thickness of the two-in-one functional glass uniform and reduce the interlayer difficulty, the thickness of the front baffle bonding layer 5 needs to be limited to be slightly larger than the sum of the thicknesses of the first bonding layer 2 and the second bonding layer 4.

The light modulation film 3 is at least one of PDLC, SPD, EC, and LC, and all the light modulation films 3 can realize the sun-shading function of the skylight area S1. The applications of various light modulation films 3 in glass are all the prior art, and the utility model is not particularly limited and will not be described herein.

The dimming membrane 3 can be formed by combining a plurality of sub-membranes, and each sub-membrane can be independently regulated and controlled, so that the dimming of partitions is realized, the dimming size can be regulated as required, and the dimming and sun shading functions and lighting are both considered.

The first light-transmitting plate 1 and the second light-transmitting plate 6 are respectively an integrally formed whole, and are different from independent skylight glass and front windshield glass on a traditional automobile, the independent skylight glass and the front windshield glass are respectively two pieces of glass, the first light-transmitting plate 1 and the second light-transmitting plate 6 are respectively an integrally formed whole, and then a sandwich process is performed to obtain two-in-one functional glass, which is equivalent to one-step obtaining of skylight glass and front windshield glass on a traditional automobile.

In one embodiment, the transmittance of the first transparent plate 1 and the transmittance of the second transparent plate 6 are greater than 90%, in order to sufficiently ensure the light transmittance of the glass and ensure the driving safety, the sun-shading function of the skylight area S1 is mainly realized by the light-regulating membrane 3, or the dark-colored first adhesive layer 2 and/or the dark-colored second adhesive layer 4 are/is adopted to enhance the sun-shading performance.

In one embodiment, the peripheral surface of the outer side of the first light-transmitting plate 1 has ink printing areas, and the ink printing areas are located at the periphery of the skylight area S1 and the periphery of the front stop area S2, so as to improve the appearance of the glass and divide the skylight area S1 and the front stop area S2.

In the present invention, the first adhesive layer 2, the second adhesive layer 4, and the front adhesive layer 5 are made of a sound insulating material, and the sound insulating performance of the functional glass product is enhanced in addition to the above embodiments, thereby improving the comfort during use of the vehicle.

The above description is intended to provide preferred embodiments of the present invention, and not to limit the present invention, and the present invention is not limited to the above examples, and variations, modifications, additions and substitutions which can be made by those skilled in the art within the spirit and scope of the present invention are also within the scope of the present invention.
