Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, and more specifically, to a laminated windshield with color-changing sunshade effect. Background Technology

[0002] Laminated glass is a composite glass product made of two or more sheets of glass with one or more layers of organic polymer interlayer sandwiched between them. After undergoing special high-temperature pre-pressing (or vacuuming) and high-temperature, high-pressure processes, the glass and interlayer are permanently bonded together. Laminated windshields are widely used in automobiles; however, existing technology has the following shortcomings in its use:

[0003] Most existing laminated glass does not have the function of changing color and shading when in use. In summer, it will cause the temperature inside the car to be too high. At the same time, the intense sunlight is not conducive to driving.

[0004] Therefore, there is an urgent need for a laminated windshield with color-changing sun-shading effect to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that most existing laminated glass does not have the function of color-changing sun shading, which leads to excessively high temperatures inside the car in summer, and the intense sunlight is not conducive to driving.

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0031] Example:

[0032] like Figure 1-4As shown, the laminated windshield with color-changing sunshade effect proposed in this embodiment includes a first frame 1, a second frame 2, and a laminated glass body 3 located between the first frame 1 and the second frame 2. The laminated glass body 3 includes a first glass layer 301, a first thin film layer 302, a transparent conductive layer 303, an electrochromic layer 304, an electrolyte layer 305, an ion storage layer 306, a second thin film layer 307, and a second glass layer 308.

[0033] The transparent conductive layer 303 is electrically connected to the vehicle's control power supply. When a voltage is applied to the electrodes at both ends of the transparent conductive layer 303, ions migrate into (or out of) the electrochromic layer 304 under the action of the electric field, causing the valence of the electrochromic material to decrease (or increase), thereby changing the color and regulating the light. This enables the laminated glass body 3 to have the function of color-changing sunshade, which can effectively prevent the temperature inside the vehicle from getting too high. When the voltage disappears, the laminated glass body 3 can return to its initial transparent state, which is beneficial for practical use.

[0034] like Figure 1 and Figure 2 As shown, both the first thin film layer 302 and the second thin film layer 307 are adhesive PET films. The first thin film layer 302 is adhered to the inner side of the first glass layer 301, the transparent conductive layer 303 is adhered to the inner side of the first thin film layer 302, the electrochromic layer 304 is tightly attached to the inner side of the transparent conductive layer 303, the electrolyte layer 305 is tightly attached to the inner side of the electrochromic layer 304, and the ion storage layer 306 is tightly attached to the inner side of the electrolyte layer 305. The ion storage layer 306 and the second glass layer 308 are respectively adhered to the opposite two sides of the second thin film layer 307.

[0035] When the first glass layer 301 or the second glass layer 308 is broken by a large external force, the adhesive effect of the first thin film layer 302 and the second thin film layer 307 can prevent the broken fragments from flying out and make them stick to the first thin film layer 302 or the second thin film layer 307, so as to avoid injury from the fragments and ensure the safety of personnel.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, sealing strips 4 are glued to the inner surface of the first frame 1 and the inner surface of the second frame 2, and the first glass layer 301 and the second glass layer 308 are respectively attached to the two sealing strips 4.

[0037] The two sealing strips 4 prevent external rainwater and dust from entering the vehicle through the gap between the laminated glass body 3 and the first frame 1 and the second frame 2, thus achieving a good dustproof and waterproof effect.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, rectangular slots 5 are provided on both sides of the second frame 2. Two rectangular positioning blocks 6 are fixedly connected to one side of the first frame 1 in a symmetrical arrangement. The two rectangular positioning blocks 6 are respectively inserted into the two rectangular slots 5.

[0039] When installing the laminated glass body 3, first place the laminated glass body 3 on the inner surface of the second frame 2, then attach the first frame 1 to the second frame 2, so that the two rectangular positioning blocks 6 are respectively inserted into the two rectangular slots 5, thereby achieving the initial positioning of the laminated glass body 3.

[0040] like Figure 1 As shown, the first frame 1 and the second frame 2 are connected by four mounting bolts 7 near the corners, and the first frame 1 and the second frame 2 are fitted together.

[0041] The first frame 1 and the second frame 2 are connected by four mounting bolts 7 to achieve the installation and positioning of the laminated glass body 3.

[0042] like Figure 1 As shown, the first frame 1 is adapted to the second frame 2.

[0043] like Figure 1 As shown, the laminated glass body 3 is attached to the first frame 1 and the second frame 2.

[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
