Zero-order-difference sealing system and automobile

The zero-order-difference sealing system comprises a sealing strip, at least one wear-resistant part is wrapped in the sealing strip, the wear-resistant part is fixedly connected with one end of a lifting part, and the other end of the lifting part is fixedly connected with glass; one end of the glass abuts against the third lip edge of the sealing strip, and the right end of the third lip edge abuts against one end of the first decoration plate, so that the automobile door glass and the B column decoration plate are located on the same plane, wind noise is effectively reduced, the appearance grade is improved, and great significance is achieved for the low wind resistance requirement of new energy and sports car types. 一种零阶差密封系统，包括密封条，所述密封条内部包裹至少1个耐磨件，所述耐磨件与升降件的一端固定连接，所述升降件的另一端同玻璃固定连接；所述玻璃的一端同所述密封条的第三唇边相抵，所述第三唇边的右端同第一饰板的一端相抵，使车门玻璃和B柱饰板在同一平面上，有效降低风噪，提升外观档次，对新能源、跑车类车型低风阻要求具有非常大的意义。
