Description

Technical Field

[0001] The utility model relates to the technical field of automobile design and manufacture, and more specifically, to a B-pillar-free door sealing component. Background Art

[0002] The B-pillar-less door sealing technology is mainly used in some car designs that pursue fashion, individuality, and functionality. Since the B-pillar is eliminated, the B-pillar-less door sealing design not only provides a smoother appearance and a convenient in-and-out experience, but also puts higher requirements on the sealing performance of the door. In the prior art, in cars without B-pillars, in order to ensure the openability of the door, the door lock 30 is generally arranged at the upper and lower edges of the door sheet metal 20 away from the hinge end. The installation of the door lock 30 increases the size of the door panel cavity, and the installation of the lock requires an open sheet metal design, which makes sealing difficult. In order to ensure the sealing of this position, it is generally set as follows Figure 1-2 The seal 40 shown in the figure is pressed together with the door seal strip and the door opening seal strip 50 to achieve sealing. However, when the vehicle is exposed to rain or washed, a large amount of rainwater will flow into the gap between the front and rear doors, and the water will flow through the avoidance opening of the seal 40 ( Figure 2 The rainwater will flow into the door lock 30 and the gap between the inner plate and the reinforcement plate (shown by the dashed line), affecting the service life of the lock. The characteristics of the B-pillar-free door sealing structure in the prior art will cause rainwater to accumulate at the seal 40 and the door opening sealing strip 50, greatly increasing the risk of water leakage in the vehicle.
