AI Technical Summary

Technical Problem

Existing door seals are easily clogged by dust and impurities in water, causing drainage to fail. They also lack a secondary sealing structure, allowing rainwater to seep into the vehicle and reduce the sealing effect.

Method used

A structure including a sealing strip snap-fit ​​body, a sealing block, a sponge strip, a rubber waterstop, a connecting hole, and a hydrophobic component is designed. The structure achieves secondary sealing by utilizing the water absorption and expansion mechanism of the sponge strip and the rubber waterstop to prevent water penetration, and the water is discharged through the hydrophobic component and the connecting cavity.

Benefits of technology

It effectively prevents dust blockage, improves the drainage efficiency and sealing effect of the sealing strip, ensures that moisture does not penetrate into the vehicle interior, and enhances the sealing performance.
