Referring to fig. 1 to 3, a luminous vehicle window glass comprises a main body layer 2 and surface layers positioned at two sides of the main body layer 2; the main body layer 2 is made of PC material, the surface layer is made of acrylic material, and patterns with patterns are pressed on the surface layer; the car window glass is bent to the bending radian required by the car window; one end of the main body layer 2 is provided with a light emitting source 5 for the main body layer 2.

In this embodiment, the acrylic material is specifically PMMA acrylic material.

In this embodiment, the light emitting source 5 is an LED light source with a control system.

In this embodiment, the light source 5 is an RGB light source, and the light source 5 is one or more of a direct light type, a side light type, and a light guide strip light type.

Referring to fig. 3, in this embodiment, the light emitting source 5 is installed in the bottom of a window or a door panel; the assembly is applied to one or more of a side window, a triangular window, a rear window and a skylight.

The manufacturing method of the light-emitting vehicle window glass sequentially comprises the following steps of: s1, obtaining the plane window glass with a main body layer 2 and surface layers positioned at two sides of the main body layer 2, wherein the main body layer 2 is made of PC materials, and the surface layers are made of acrylic materials;

s2, pressing a pattern with a pattern on the surface layer of the plane car window glass;

s4: the light source 5 is arranged at the invisible position of the lower edge of the vehicle window, the light emitting direction of the light source is directly upward along the main body layer 2, and the pattern area is lightened along with the light source.

It should be noted that, in the implementation process, if the traditional glass material is used, since the pattern is pressed first and then the pattern is bent, the pattern pressed is damaged in the high-temperature environment during the bending of the pattern; if the glass is bent and molded first and then the patterns are pressed, the difficulty of pressing the patterns is high, which is not beneficial to the implementation of the scheme. Therefore, in the manufacturing process, the PC and the acrylic material which are required by bending and have lower temperature are adopted, and compared with the traditional glass material, the pattern can be firstly pressed, so that the vehicle window glass can be bent and molded at high temperature, the pattern cannot be damaged due to overhigh temperature in the bending and molding process, the scheme is easier to realize, and the cost is lower.

As shown in fig. 1, the material of the PC side window is shown to replace the existing glass. The two outer sides contain a small amount of acrylic, thereby providing better abrasion resistance.

As shown in figure 2, the side window glass is a schematic drawing of the novel side window glass modeling, patterns are directly engraved on the surface of a side window through an embossing technology, and the side window is shaped and then cut, formed and bent under high pressure. As shown in fig. 3, which is a schematic view of a side window assembly structure, 1 is a roof, 2 is a main body layer of a PC window, 3 is a surface pattern, 4 is a door, 5 is an LED light source and a control system, and is disposed in the door. The key structures needed to implement the functionality of the present invention are 2, 3, 5.

The micro-pattern is imprinted on the PC glass, and the light source is disposed at one side, and internally propagates by light, coming out from the pattern particles, showing the design effect. The light source can be direct-emitting, side-emitting, light guide strips and the like, and is arranged at the bottom of a window or in a door plate, and the assembly can be applied to a side window, a triangular window, a rear window, a skylight and other transparent parts. The light source can be RGB, and the warning and atmosphere effects can be bright colors.

The invention uses plastic to replace glass, imprints micro-patterns on the surface of the PC board, and then can be bent into a car window or other car transparent shapes through laser cutting and high-pressure forming. The light source is selectively arranged at the invisible position of the lower edge, the LED is directly upwards along the side window, and the patterned area is lightened along with the LED. The pattern modeling is designed on the offset plate, the micro pattern in the pattern can be assumed to be a set of points with the size equivalent to 25um, the distance between each point is 50um, the numerical values can be adjusted, the minimum size of each point can be 0.1-1um, and the distance can also be adjusted according to the effect. Then, the offset plate mold is pressed on the PC plate (the outer surface of the plate is provided with a PMMA acrylic coating, and a 2-5mm thick plate can be integrally formed by co-extrusion compounding). At the moment, the micro-patterns are not easy to be perceived under common light, and the light can directly penetrate through the micro-patterns, so that the requirement of transmittance is met. The light source is arranged on the side edge of the plate, so that light rays are transmitted in the plate, patterns on the surface of the plate are lightened, and the whole assembly can be arranged at a transparent position of a vehicle body, so that the side window and the rear window are more distinctive.
