Description

Glass component

Technical Field

The utility model belongs to the technical field of glass, specifically relate to a can regard as car glass's glass subassembly.

Background

As the amount of glass used in automobiles increases, the function of the automobile glass is receiving more and more attention. At present in the automobile manufacturing field, the mode of using sunroof or sky curtain as ventilation and sight scene is very common, traditional car glass does not possess thermal-insulated heat preservation function, because sunshine is great and present high temperature weather is frequent in summer, under the continuous irradiation of sunshine, temperature very easily risees in the car, and then lead to getting into to drive because the inside temperature of vehicle is higher leads to driving experience not good before, and can only open the window and open the air conditioner through the driver before driving at present and solve, but need time like this, and the air conditioner needs the electric energy to supply with at the during operation, and can only open after only the driver gets on the car, if open in advance and lead to the battery to have the electric quantity easily, lead to the vehicle can't start. In winter, especially in northern winter, heat inside the automobile is easy to lose through the automobile glass, so that the interior of the automobile is very cold, the outer surface of the automobile glass is easy to freeze and accumulate snow, and the sight of people looking outside the automobile from the interior of the automobile is blocked.

In order to solve the problems of the automobile glass in summer and winter, people make a lot of efforts, but the problems are not ideal. For example, the existing automobile glass capable of generating power is formed by clamping an opaque solar cell between two pieces of glass, the solar cells comprise a silicon wafer cell, an amorphous silicon thin film cell, a copper indium gallium selenide base thin film cell, a perovskite thin film cell, an organic solar cell and the like, and the automobile glass only has the function of generating power but cannot have the property of being transparent on the whole surface, so that the essence of the automobile glass for observing the external environment is lost.

In order to achieve the purpose of partial region transparency, some of the automobile glass capable of generating power is etched by laser etching (such as a thin film solar photovoltaic automobile glass assembly disclosed in patent publication CN 201410013602), or silicon wafers are arranged at intervals, so that light is transmitted at the intervals between the silicon wafers to achieve the purpose of partial region transparency (such as a solar landscape skylight for an automobile disclosed in patent publication CN 201220731431.1).

The automobile glass can achieve the whole surface transparency, but the automobile glass cannot generate electricity and only has certain heat insulation effect, but the heat insulation effect is not ideal, and the total solar transmittance is higher.

In summary, there is no multifunctional automobile glass that can provide transparent whole surface, heat insulation and power generation. With the increasing use amount of glass designed for automobiles and the increasing popularization of new energy automobiles, more requirements are put forward on the functions of the automobile glass. Therefore, there is a need for an automotive glass having the above-mentioned functions.
