In the description of the present application, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments in accordance with the present application. For ease of description, the dimensions of the various features shown in the drawings are not drawn to actual scale. Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate. In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.

In the technical scheme, by adopting the three-layer 8mm glass layer structure design, the bullet-proof glass can not only play a role in buffering impact on bullet-proof after being impacted by the bullet, but also prevent the bullet from penetrating through the whole glass; PVB is characterized by its very strong impact resistance, so that even if the glass ply breaks, the interlayer disposed within the glass structure prevents the bullet from penetrating the entire glass; EVA is a high molecular polymer formed by copolymerizing ethylene and vinyl acetate, has ultrahigh transparency, has the characteristics of heat preservation and heat insulation, and provides good heat preservation and heat insulation performances for a whole glass structure. Regarding the monolithic bullet-proof glass structure, specifically, the first layer 100 is the innermost layer, the seventh layer 700 is the outermost layer, and the PVB layer is set to the second layer 200 so as to prevent bullets from passing through the first glass layer, and a liquid crystal film layer is arranged between the second glass layer and the third glass layer, so that the effect of intelligent dimming is achieved through the liquid crystal film layer, dimming can be achieved only after the liquid crystal film layer needs to be electrified, and in order to improve the transparency of glass, the first EVA layer and the second EVA layer are respectively arranged on two sides of the liquid crystal film layer.
