Stamping car door zero-surface-difference B column section and top section structure

Abstract

The invention relates to a stamping car door zero-surface-difference B column section and top section structure which is used for sealing car door lifting glass and comprises a B column sealing strip structure and a top section sealing strip structure, the B column sealing strip structure is provided with a plastic sliding block parallel to the direction of the car door lifting glass, the sliding block is embedded in a sliding rail sealing strip, the sliding block drives the lifting glass to slide up and down in the sliding rail sealing strip and is matched with the glass guide groove sealing strip to form sealing, and the X / Y direction of the sliding block is matched with the sliding rail sealing strip and the glass guide groove to limit the X / Y direction displacement of the glass; a top section in the top section sealing strip structure is installed on an inner plate of a vehicle door, a hollow bubble-shaped structure is arranged at the contact position of the top section and glass and used for achieving the buffering and noise reduction effects when the glass is lifted to the top, the top sealing strip section is connected to the inner plate of the vehicle door in a clamped mode, and a mushroom head clamping bright strip is arranged on the top sealing strip section. The bright strip covers the appearance surface of the top section, so that the attractive effect of reducing rubber leakage is achieved.

Description

technical field [0001] The invention relates to a B-pillar cross-section and a top cross-section structure of a stamped car door of an automobile, in particular to a stamped car door with a zero-surface-difference B-pillar cross-section and a top cross-section structure. Background technique [0002] The top section of the traditional car door glass run channel is installed on the inner panel of the door. The rubber leakage surface of the section body is more, and the Y-direction distance between the top section and the glass is generally greater than 5mm, and the Y-direction gap between the glass and the decorative panel at the B-pillar is also If it is greater than 5mm, the Y-direction gap between the top and the B-pillar is 5mm to form a step difference. This step difference will increase the drag coefficient of the vehicle and the appearance is not beautiful enough. From the perspective of the drag coefficient of the vehicle and the appearance, it is urgent to develop a z...

[0002] The top section of the traditional car door glass run channel is installed on the inner panel of the door. The rubber leakage surface of the section body is more, and the Y-direction distance between the top section and the glass is generally greater than 5mm, and the Y-direction gap between the glass and the decorative panel at the B-pillar is also If it is greater than 5mm, the Y-direction gap between the top and the B-pillar is 5mm to form a step difference. This step difference will increase the drag coefficient of the vehicle and the appearance is not beautiful enough. From the perspective of the drag coefficient of the vehicle and the appearance, it is urgent to develop a zero surface Poor door sealing system structure. At present, the models with zero surface difference on the glass side in the market are generally high-end luxury cars with frameless doors. Frameless door seals are expensive, costly, and complicated to manufacture. Based on the above requirements, Development of a low-cost, simple-process new car door zero-surface-difference top section, B-pillar section structure and sealing strip
