Embodiment 1

[0043] The invention discloses an electrochromic automobile windshield glass device, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the upper part of the windshield includes a laminated windshield glass with two layers of ITO electrode films 2 and bistable liquid crystals 4 . The power of the power supply appliance 8 is controlled by the driver IC 7 and the sunlight sensor 6 . The laminated windshield glass is float glass, the lower part of which contains a PVB (polyvinyl butyral) layer 5 . The ITO electrode thin film 2 is made by sputtering coating process, and has a thickness of 200 nm and is transparent. The thickness of the bistable liquid crystal 4 is 1.52 mm.

[0044] The preparation method of the electrochromic automobile windshield glass device of the present embodiment comprises the following steps:

[0045] Step 1: Cut the windshield glass substrate 1 (trapezoidal cutting, the length of the upper and lower parallel lines of the glass are 1100mm, ...

Abstract

The invention provides an electrochromic automotive windshield glass device comprising a piece of PVB interlayer windshield glass including an ITO electrode film and a bistable liquid crystal and a driver IC connected with a sunlight sensor and a power source device. According to the invention, the electrochromic automotive windshield glass device has the safety of the PVB laminated glass and thehigh-efficiency shading of the electrochromic unit. And the shading area and the shading intensity of the windshield glass can be adjusted efficiently in real time.

Description

technical field [0001] The invention relates to a vehicle windshield glass device, in particular to a vehicle windshield glass device capable of identifying the intensity and direction of light so as to electrochromize. Background technique [0002] During the driving process of the vehicle, the external environment is a constantly changing process, and the driver is often affected by strong light, which affects the safety of driving and driving. Therefore, there are different shading solutions on the market for different models. For large passenger cars and trucks, the combination of sunshade cloth and sunglasses is more common. There is a fixed sunshade cloth in the car to adjust the amount of shading, and then supplemented by sunglasses to prevent direct sunlight from reaching the driver's eyes. However, the shade cloth cannot be changed with the change of the light direction, and the driver needs to manually adjust it. At the same time, the sunglasses are not conducive ...
