Abstract

El uso de sistemas de seguridad basados en cámaras está creciendo a un ritmo acelerado en los automóviles modernos. De la misma manera, los parabrisas, donde muchas de las cámaras son montadas, cada vez son más grandes y de formas más complejas A medida que la industria avanza hacia el desarrollo de vehículos con capacidad autónoma, el número de cámaras requeridas y la resolución de las mismas aumentan. Sin embargo, la calidad óptica del parabrisas es menor que la óptima. Uno de los problemas es causado por la típica frita de esmalte negro que se imprime en el vidrio, antes de calentarse y curvarse, para ocultar u oscurecer los componentes de la cámara. Los abruptos gradientes térmicos durante el curvado, causados por que la frita negra absorbe el calor, dan como resultado un alto nivel de distorsión en el campo de visión de la cámara. El objeto de la presente invención es proporcionar un vidrio laminado para automotores que tiene un área de oscurecimiento producida al crear el oscurecimiento después del calentamiento y curvado del vidrio, aplicando un inserto delgado sustancialmente opaco a al menos una de las superficies de la capa adhesiva de plástico intermedia, laminas delgadas o capas de vidrio en o cerca del campo de visión de la cámara que posteriormente sirve como el oscurecimiento en lugar de imprimir y cocer una frita de esmalte sobre el vidrio. Esto da como resultado un laminado que posee una calidad óptica superior, una mayor resistencia y una menor probabilidad de rotura en comparación a un laminado con un oscurecimiento de banda negra.The use of camera-based security systems is growing at a rapid rate in modern automobiles. In the same way, windshields, where many of the cameras are mounted, are getting larger and more complex in shape. As the industry moves towards the development of autonomous capable vehicles, the number of cameras required and the resolution of they increase. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is imprinted on the glass, prior to heating and curving, to hide or obscure the camera components. Steep thermal gradients during bending, caused by the black frit absorbing heat, result in a high level of distortion in the camera's field of view. The object of the present invention is to provide an automotive laminated glass having an area of darkening produced by creating darkening after heating and bending of the glass by applying a substantially opaque thin insert to at least one of the surfaces of the adhesive layer of intermediate plastic, thin sheets or layers of glass in or near the camera's field of view that subsequently serves as the darkening rather than printing and firing an enamel frit on the glass. This results in a laminate that has superior optical quality, greater strength, and a lower probability of breakage compared to a laminate with a black band darkening.
