Problems solved by technology

This solution uses a whole piece of color-changing film to shade the sun through the change of light transmittance, and the higher the energized voltage, the higher the transparency. When there is a problem with the vehicle circuit, the color-changing film will be opaque, which will directly affect driving safety; claim 6 of the patent application for the invention also records that it has a function prohibition switch, which is also contradictory to the patent application for the invention, and it is prohibited to open When the color-changing film is not powered on, it is in a completely blurred state, and the driver cannot see the road ahead, which affects driving safety.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing explain as follows:

[0016] like figure 1 As shown, the human eye position 3 refers to the human eye position of the front passenger in a normal sitting posture. When the strong light 1 from the outside is irradiated into the front windshield 4 of the cab, it will pass through the electrochromic film group 2 installed in the sunshade area of ​​the front windshield 4 and then enter the human eye position 3 .

[0017] like figure 2 As shown, the control system controls the circuit on-off and voltage of each electrochromic film in the electrochromic film group 2 according to the intensity and angle of light irradiated into the front windshield 4 of the cab, so that it can irradiate the human eye position 3 The light transmittance of the electrochromic film that passes through the strong light 1 is reduced, blocking the strong light from entering the human eye, and the electrochromic film that does not irradiate the human e...

Abstract

The invention discloses sunshade glass and a sunshade method for an automobile. The sunshade glass and the sunshade method have the advantages that an electrochromic film group which comprises a plurality of electrochromic films is mounted in a set sunshade region on a front windshield of the automobile, closing and opening of circuits and voltages of each electrochromic film are managed by control systems, accordingly, the light transmittance of each electrochromic film can be controlled, and the purpose of shielding hard light with influence on the driving safety and the comfort can be achieved.

Description

technical field [0001] The invention relates to an automobile sunshade system, in particular to an automobile sunshade glass and a sunshade method thereof. Background technique [0002] When people are driving, sometimes their eyes are easily exposed to strong sunlight, especially in the morning and afternoon of sunny weather. In this case, the front row personnel generally use traditional sun visors or sun shades to block sunlight from shining on the eyes. [0003] The use mode of sunshade plate or sunshade curtain is that people adjust the turnover angle of sunshade plate themselves according to the angle of light irradiation, or prevent strong light from shining in eyes by launching and reclaiming sunshade curtain. In consideration of the safety of the front row occupants, sun visors or sun visors need to consider many factors such as hardness, strength, size, installation position, etc. when developing sun visors, and many tests such as special sun visor simulated head ...
