Description

Technical Field

[0001] The utility model belongs to the technical field of automobile B-pillars and relates to a semi-transparent black ink structure of an automobile B-pillar. Background Art

[0002] With the acceleration of the development of automobile intelligence, more and more sensors are arranged on the body, and the cover with intelligent B-pillar is applied in more and more scenarios. The intelligent B-pillar integrates ADAS cameras and translucent graphics, and can also be hidden in the off state. Translucent graphics and cameras are gradually added to the body. In addition to improving the performance and technological sense of the intelligent B-pillar, the aesthetic of the details hidden after the graphics are turned off is also very important. At present, in the existing intelligent B-pillars of automobiles, high-temperature sintering ink is used to print on the glass, and the whole is shielded. The traditional high-temperature sintering ink cannot achieve a semi-transparent effect, and the shielding of the main body is poor. It cannot be used in scenes with backlight sources. Therefore, the traditional process graphic area is hollowed out and an indicator light is installed. The position of the indicator light is abrupt, or the graphic area is hollowed out and printed, and a light source is added to the hollow position. When the graphic is not translucent, there is a very obvious color difference between the graphic area and the main body color, and there is no aesthetic feeling. Conventional high-temperature sintering ink belongs to the inorganic ink system, which cannot achieve a semi-transparent effect. At the same time, after the inorganic ink is sintered into a film at high temperature, the shielding is poor. After the back light source is lit, the pinhole light transmission problem can be seen on the front. Utility Model Content
