Technical Field
The utility model relates to a glass especially relates to a front windshield and contain this windshield's car with rain, fog volume detects function.
Background
The traditional rain and fog sensor for detecting the rain and fog on the automobile windshield is arranged in the windshield, and although the rain and fog on the windshield can be detected by the arrangement mode, the arrangement mode has the following defects:
1. the electrodes of the traditional rain and fog sensor are made of opaque materials, so that the electrodes of the rain and fog sensor are required to be arranged at a certain position of the windshield glass and cannot be arranged at any position on the windshield glass. The arrangement mode can cause the fog amount and the rain amount measured by the rain and fog sensor to be inaccurate, because the rain amount and the fog amount are distributed on the windshield in a discrete mode, the rain and fog sensor arranged at a certain position of the windshield can not detect the rain and fog on the windshield in time, and therefore the rain and fog amount detected by the traditional rain and fog sensor is inaccurate, and finally a windshield wiper system and a defogging system on an automobile can not act in time.
2. Traditional rain fog sensor needs huge space demand to the setting mode that two electrodes with fog volume detection electric capacity and rain volume detection electric capacity all set up on glass can influence windshield's aesthetic measure, can't satisfy user's visual requirement.
To solve the above problems, utility model No. 201780003059.8 discloses a composite glass panel with an interior chamber separated from the external environment, comprising an inner glass panel, an outer glass panel having an inner side surface, and an intermediate layer joining the inner side surface of the outer glass panel face to face with the outer side surface of the inner glass panel, a capacitive sensor for detecting moisture having at least one capacitor connected to sensor electronics configured to detect a change in capacitance of the capacitor, wherein the capacitor has at least two electrodes formed by a transparent conductive coating and capacitively coupled.
This patent overcomes the above-mentioned drawbacks of conventional rain and fog sensors by providing a transparent conductive layer between two glass plates and electrodes of a capacitive sensor on the transparent conductive layer. However, the patent still has the following disadvantages:
when the capacitive sensor detects the rainfall outside the vehicle, the fog inside the vehicle can interfere with the capacitive sensor, and the temperature and electromagnetic changes outside the vehicle can also interfere with the capacitive sensor, so that the capacitive sensor cannot accurately detect the rainfall outside the vehicle, and the capacitive sensor cannot feed an accurate rainfall signal back to the controller for controlling the action of the windshield wiper to control the windshield wiper system to correspondingly act; meanwhile, when the capacitive sensor detects the amount of fog in the vehicle, the amount of rain outside the vehicle, the temperature in the vehicle, electromagnetic changes and the like also cause interference to the capacitive sensor, so that the capacitive sensor cannot accurately detect the amount of fog, and further the capacitive sensor cannot feed an accurate fog amount signal back to the air conditioner controller to control the air conditioner defogging system to correspondingly act.
Therefore, it is necessary to develop a glass capable of overcoming the mutual interference between the rainfall sensor and the fog sensor and simultaneously eliminating the interference of the external temperature and the electromagnetic change.
