AI Technical Summary
Existing frameless door sealing strips are prone to adhesive noise in terms of NVH performance, have insufficient sealing reliability, are prone to failure under high-speed aerodynamic loads, have complex manufacturing processes and high assembly precision, and are prone to sealing failure and appearance defects.
Design a frameless sealing strip comprising a dense gel and a sponge gel. The dense gel has a sealing cavity at the bottom, and the sponge gel contacts the door glass, fitting tightly through elastic deformation. Combined with serrated protrusions and a wear-resistant coating, friction noise is reduced. It is connected to the side trim piece by fastening components such as clips and double-sided tape to ensure stable installation.
It improves the aesthetics and structural strength of the sealing strip, effectively blocks wind, water and noise, reduces friction noise, enhances connection strength and sealing reliability, optimizes NVH performance, and extends service life.
