Description
Technical Field
[0001] The utility model belongs to the technical field of automobile B-pillars and relates to a structure on an automobile B-pillar with hidden luminescence. Background Art
[0002] With the rapid development of intelligent vehicles, more and more sensors are being deployed in vehicle bodies, and smart B-pillar covers are being used in more and more scenarios. Smart B-pillars integrate intelligent driving cameras and translucent graphics, which can also be hidden when the vehicle is turned off. Translucent graphics and cameras are also gradually being added to vehicle bodies. In addition to improving the performance and technological sense of smart B-pillars, the aesthetic details of the hidden graphics when they are turned off are also important. Currently, existing smart B-pillars in automobiles are printed on glass using high-temperature sintered inks, which are used for overall masking. Traditional high-temperature sintered inks cannot achieve a semi-transparent effect, and the main body has poor shielding properties, making them unsuitable for use in scenes with backlights. Therefore, traditional processes hollow out the graphic area and then install indicator lights, which are relatively abrupt. Alternatively, the graphic area is hollowed out and a light source is added to the hollowed-out area. When the graphic is not translucent, there is a very obvious color difference between the graphic area and the main body, which lacks aesthetic appeal. Utility Model Content
