Problems solved by technology

Compared with the sun visor dimming film made of traditional nematic liquid crystal, the electro-switchable glass using liquid crystal polymer technology has greater transparency, but this liquid crystal polymer technology is not "multi-stable". state", which, like traditional nematic liquid crystals, requires continuous power supply to maintain a transparent state

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1 to Figure 3 As shown, the electronically controlled dimming automotive sun visor of the present invention includes a main body plate, which includes a glass body 1 and a base layer 2, and the base layer 2 is glass or plastic, such as a transparent plastic film or a 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 of smectic liquid crystals are arranged in a lay...

Abstract

The invention discloses an electrical control light-dimmer automobile sun shield which comprises a subject panel 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 layer facing 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 a front and a back sun shields of the automobile 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 shield can effectively block out incident light in time, so as to enhance the comfortableness of the driver and passenger, save electricity and being healthy and environment-friendly.

Description

technical field [0001] The invention relates to an automobile sun visor, in particular to a front and rear sun visor of an automobile with an electronically controlled dimming function. Background technique [0002] The front and rear sun visors of the automobile mainly include a main body plate, which is generally made of leather or plastic and is opaque. When not in use, manually fold the sun visor over the roof of the car, and when in use, manually fold the sun visor down to block out the light. And now the car more and more advocates the comfort of the driver and the passengers, thus, the manual operation of the sun visor is obviously contrary to the development trend of modern automotive electronics. [0003] At present, a known electric dimming sun visor can be fixed on a certain position in the car, and the intensity of shading can be adjusted according to the intensity of incident light. The electric dimming sun visor uses a dimming film, which is made of tradition...
