Windshield having rainfall and fog detecting function and electronic shielding function

Abstract

The invention provides a windshield having a rainfall and fog detecting function and an electronic shielding function. The windshield comprises an outer glass plate and an inner glass plate between which at least a first transparent conductive layer for sensing the rainfall and a second transparent conductive layer for sensing the fog are arranged. The windshield comprises an electronic sunshade area, a rainfall sensing area and a fog sensing area. A liquid crystal layer conductive layer is disposed between the two transparent conductive layers corresponding to the electronic sunshade zone. Atleast three independent rainfall electrodes are disposed in an area corresponding to a rainfall sensing area. On the conductive layer, at least two independent fog electrodes are disposed in an areacorresponding to a fog sensing area, and a plurality of mutually insulated electrically conductive regions or an entire electrically conductive region are/is disposed in an area corresponding to the electronic sunshade area. An ambient light sensor is disposed on the front windshield or a dashboard. The windshield is reduced in cost by sharing the same conductive layer with an electronic curtain and a capacitive touch sensor sensing electrode.

Description

technical field [0001] The invention relates to a glass, in particular to a windshield with rain and fog detection functions and electronic covering functions and an automobile containing the windshield. Background technique [0002] The traditional rain and fog sensor used to detect the amount of rain and fog on the windshield of the car is set inside the windshield. Although this setting method can measure the amount of rain and fog on the windshield, this setting method has the following defects: [0003] 1. The electrodes of the traditional rain and fog sensors are made of opaque materials, so the electrodes of the rain and fog sensors are required to be set at a certain position on the windshield, and cannot be set at any position on the windshield. This setting method will lead to inaccurate fog and rain measured by the rain and fog sensor. This is because the rain and fog are distributed discretely on the windshield, so the rain and fog sensor installed at a certain p...

AI Technical Summary

Problems solved by technology

[0003] 1. The electrodes of the traditional rain and fog sensors are made of opaque materials, so the electrodes of the rain and fog sensors are required to be set at a certain position on the windshield, and cannot be set at any position on the windshield

This setting method will lead to inaccurate fog and rain measured by the rain and fog sensor. This is because the rain and fog are distributed discretely on the windshield, so it is very likely that the rain and fog sensor installed at a certain position on the windshield will The rain and fog on the windshield cannot be detected in time, so that the amount of rain and fog detected by the traditional rain and fog sensor is inaccurate, and eventually the wiper system and defogging system on the car cannot be activated in time

[0004] 2. The traditional rain and fog sensor requires huge space requirements, and the traditional setting method of setting the two electrodes of the fog detection capacitor and the rain detection capacitor on the glass will affect the aesthetics of the windshield and cannot satisfy the user's vision Require

[0015] The above patents cannot control the opening and closing of the electronic sun visor through gestures, let alone control the extension of the electronic sun visor through gestures
