Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle door sealing, and in particular relates to a zero-face difference vehicle door sealing system. Background Art

[0002] At present, the traditional automobile door structure is mainly divided into stamping door system and rolling window frame door system structure according to the sheet metal manufacturing process. Its characteristics are that the front and rear doors and the side assembly components of the body side are not flush with the movable glass surface, and there is a Y-direction step surface difference, which affects the appearance consistency and increases the side drag coefficient during vehicle driving. In addition, the Y-direction position of the movable glass during the lifting process is controlled only by the compression load of the sealing strip lip, which cannot ensure the stability of the movable glass position. The sealing force between the sealing strip sealing lip and the movable glass will also be uneven and fluctuate during the lifting process, which seriously affects the sealing performance.

[0003] At present, the patented structure of the zero-face difference door system of automobiles has solved the concept of "flush" appearance of the side of the door, but it has extremely high requirements for the manufacturing and assembly precision of the door system components, resulting in an increase in component costs. In addition, the width of the black border from the moving glass to the edge of the trim or the edge of the guide rail is much larger than that of the traditional door system, which affects the field of vision and appearance. When the glass is lowered, the complex structure of the system affects the overall aesthetics of the appearance. In addition, there are many restrictions on the limiting structure of the moving glass slider and the sealing strip, which imposes additional restrictions on the assembly and integration of system components and affects the installation efficiency.

[0004] Based on this, a zero-face difference door sealing system is proposed. Utility Model Content
