Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts, especially relates to a split type automobile B column structure. BACKGROUND
[0002] In the use process of the automobile, the interior trim of the automobile will volatilize organic compounds (VOCs), especially in the case of direct sunlight or high temperature in the car, the organic compounds will accelerate volatilization into the air in the car due to the temperature rise. When these volatile substances meet the surface of the car window or windshield with lower temperature, condensation phenomenon will occur on the surface, forming a thin fog film. The "fog film" formed by atomization will reduce the transparency of the glass, making the driver's vision become blurred, thereby affecting the judgment of the road conditions and increasing the risk of traffic accidents.
[0003] At present, a camera is installed on the automobile B column, and the automobile B column is attached to the glass, and the camera shoots the road surface through the glass. The volatilized organic compounds on the automobile B column will cause the glass to atomize, so that the camera cannot obtain clear images, affecting the auxiliary driving function and driving safety of the vehicle. In order to solve this problem, the material of the automobile B column can be replaced with a material with excellent low-fogging performance, but the B column structure of the domestic automobile industry is mostly designed in an integrated manner. This design method is easy to implement to some extent, and can meet the basic requirements of vehicle body strength and structural stability under the traditional manufacturing process. However, if the entire structure is replaced with a material with excellent low-fogging performance, the production cost will be greatly increased, which is not easy to popularize.
