All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a vehicle including a window glass. The window glass will be described as follows.
Referring to fig. 1 to 3, a window glass includes: the glass layer 10, the pattern structure 20 and the background layer 30, wherein the pattern structure 20 is arranged on the glass layer 10, the background layer 30 is formed on the glass layer 10, and the projection of the background layer 30 on the glass layer 10 at least covers the partial projection of the pattern structure 20 on the glass layer 10. It will be appreciated that the background layer 30 covers all of the patterned structure 20, or that the background layer 30 covers a portion of the patterned structure 20, whereby the glazing may produce a different aesthetic appearance. When the window glass is used on a vehicle, the background layer 30 is closer to the vehicle interior side than the pattern structure 20, the background layer 30 can shield the interior and can serve as a background against the pattern structure 20, and the pattern structure 20 can be more clearly observed through the glass layer 10 from the vehicle exterior side. The background layer 30 may be a dark ink, such as a black ink, a brown ink. It can be understood that the vehicle window glass comprises the see-through region 110 and the functional region 120, the visible light transmittance of the see-through region is 10% to 95%, the visible light transmittance of the functional region 120 is less than 10%, preferably less than or equal to 5%, and more preferably less than or equal to 1%, the region covered by the pattern structure 20 and the background layer 30 on the glass layer 10 forms the functional region 120, and the region not covered by the pattern structure 20 and the background layer 30 on the glass layer 10 forms the see-through region 110; in fig. 1, the functional region 120 surrounds the see-through region 110, and the pattern structure 20 is disposed in the functional region 120; in fig. 2, the functional area 120 surrounds the see-through area 110, and the pattern structure 20 is disposed on the functional area 120 and passes through the see-through area 110.
In this application, through set up pattern structure 20 in window glass, changed window glass's appearance for window glass's appearance can be for a variety, and window glass can have more advanced visual characteristic when observing from the car outside, promotes aesthetic appearance, and pattern structure 20 can also match with the outward appearance of other positions of automobile body (for example roof, D post etc.), realizes the whole uniformity of automobile body outward appearance, satisfies more molding designs of car.
In a specific embodiment, the color difference δ E between the pattern structure 20 and the glass layer 10 * Greater than or equal to 5, and/or a color difference deltaE between the pattern structure 20 and the background layer 30 * Greater than or equal to 5.
In the present application, the above-mentioned color difference δ E between the pattern structure 20 and the glass layer 10 is set * The above-mentioned color difference δ E between the pattern structure 20 and the background layer 30 * Satisfies the color difference delta E recognizable by the pattern structure 20 * When satisfying window glass and promoting aesthetic appearance demand, can also be convenient for people's eye discernment easily, promote pattern structure 20's distinguishable degree.
In one specific embodiment, the chromaticity variation δ C of the pattern structure 20 and the glass layer 10 * Greater than or equal to 2.5, and/or a chromaticity variation deltaC of the pattern structure 20 and the background layer 30 * Greater than or equal to 2.5.
In the present application, the above-mentioned chromaticity variation δ C of the pattern structure 20 and the glass layer 10 is provided * The chromaticity fluctuation δ C of the pattern structure 20 and the background layer 30 * The recognizable chromaticity fluctuation of the pattern structure 20 is met, the aesthetic appearance requirement of the window glass is met, human eyes can be conveniently recognized easily, and the recognizable degree of the pattern structure 20 is improved.
It is understood that the recognition of colors by the human eye is judged in CIELAB color space by lightness and chroma. L used in the International Commission on illumination CIE 1976 * Represents lightness, L * Has a value range of [0,100 ]]，a * (Green and Red), b * (blue and yellow) is chroma, a * Has a value range of [ -128,127 ]]，b * Has a value range of [ -128,127 ]]. The color difference of two colors can be represented by delta E * The chromaticity fluctuation can be represented by δ C * And (4) showing. To reduce the effect of brightness, more considering the color difference, we calculate δ E * The ratio of brightness can be reduced by the following formula: delta E * ＝((δL * /2) 2 +(δa * ) 2 +(δb * ) 2 ) 1/2 ,δE * The smaller the difference, the closer the two colors are, and conversely, the larger the difference between the two colors. Chromaticity fluctuation δ C * ＝C1 * -C2 * Wherein the color number C * ＝((a * ) 2 +(b * ) 2 ) 1/2 Chromaticity fluctuation δ C * The smaller the two colors are, the closer the two colors are to each other, whereas the two colors fluctuate more strongly. I.e. delta E * And δ C * The larger the pattern structure 20, the easier it is to recognize.
For example, if the glass layer 10 is green glass and the pattern structure 20 is red, δ E * ＝103，δC * =96, remarkable color difference and chromaticity fluctuation can be achieved, the pattern structure 20 can be easily identified, and the identifiability is high; when the glass layer 10 is green glass and the pattern structure 20 is white, δ E * ＝5.06，δC * =4.21, the pattern 20 may still be recognized, but the recognizability is reduced, and the red pattern 20 may produce a more distinct visual contrast than when the glass layer 10 is green. Color difference delta E between the pattern structure 20 and the glass layer 10 of the present application * Greater than or equal to 5, and the chromaticity fluctuation deltaC between the pattern structure 20 and the glass layer 10 * Greater than or equal to 2.5 may cause the pattern structure 20 to meet the identified requirements. Of course, the present application may be based on the δ E of the different glass layers 10 and pattern structures 20 * Difference, other matching combinations are selected as long as δ E described above is satisfied * Required, or satisfy δ E * And δ C * The requirements can be met, and the application is not listed.
If the background layer 30 is black and the pattern structure 20 is white, δ E * ＝47.5，δC * =0.58; the background layer 30 is black and the pattern structure 20 is red, δ E * ＝106，δC * =100; the background layer 30 is black and the pattern structure 20 is gray, δ E * ＝19.9，δC * =3.8. Therefore, the color, the chromatic aberration and the chromaticity fluctuation of different combinations are different. The color difference delta E between the pattern structure 20 and the glass layer 10 * Greater than or equal to 5, a color difference δ E between the pattern structure 20 and the background layer 30 * Greater than or equal to 5 may cause the pattern structure 20 to meet the identified requirements. Of course, the present application may be applied according to the δ E of the different background layers 30 and pattern structures 20 * Difference, other matching combinations are selected as long as δ E described above is satisfied * The method is required.
