Problems solved by technology

Compared with the sunroof dimming film made of traditional nematic liquid crystal, the electro-dimmable glass using liquid crystal polymer technology has greater transparency, but this liquid crystal polymer technology is not "multi-stable" ", just like the traditional nematic liquid crystal, it needs continuous power supply to maintain the transparent state

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 3 As shown, the electronically controlled dimming automobile sunroof of the present invention includes a glass window, a sealing rubber strip and a driving mechanism. The glass window includes a glass body 1 and a base layer 2, and the base layer 2 is glass or plastic, such as transparent plastic film, transparent hard plastic plate. A mixed layer 3 is arranged between the glass body 1 and the matrix layer 2, and the mixed layer 3 is formed by mixing smectic liquid crystals and additives. Generally, the thickness of the mixed layer 3 is controlled at 2 microns to 30 microns. In the mixed layer 3, the smectic liquid crystals account for 90% to 99.999% of the total weight of the mixture, and the additives account for 0.001% to 10% of the total weight of the mixture. Usually, at room temperature ± 50°C, the molecular clusters...

Abstract

The invention discloses an electrical control light-dimmer automobile sun roof which comprises a glass window that includes a glass body and a substrate layer, wherein, a mixed layer is arranged between the glass body and the substrate layer and is formed by mixing smectic phase liquid crystal and additive; both the side of the glass body facing the mixed layer and the side of the substrate layerfacing the mixed layer are provided with a leading electrode layers that are connected with a circuit drive control device. As electrical signals applied on the leading electrode layers are controlled, the smectic phase liquid crystal molecules take on different arrangement states which are kept stable and constant under the electroless condition, thus automobile sun roof can be switched between the state of vaporific shading and the full transparent state, even be switched among multiple gradual progress states with different grayscales; the automobile sun roof enhances the comfortableness of the driver and passenger, saves electricity, has rapid switching speed, and is healthy and environment-friendly.

Description

technical field [0001] The invention relates to an automobile sunroof, in particular to an automobile sunroof with an electric control dimming function. Background technique [0002] The car sunroof is mainly composed of a glass window, a sealing rubber strip, a sun visor and a driving mechanism. The opening forms generally include external opening type, built-in type and inclined type. But no matter in what way to control the opening of the car sunroof, the central glass window is the main part of the car sunroof, and the sunroof used on the car at present is mainly the common glass that has pasted the film. Now cars are more and more advocating the comfort of drivers and passengers. The trend of sunroof is to gradually increase the area of ​​glass windows, and there are more and more panoramic sunroofs. As a result, the manual or electric sunshade of the entire sunroof is obviously contrary to the development trend of modern automotive electronics. [0003] At present, a...
