A multi-layer composite weatherstrip for reducing wind noise

Abstract

The utility model relates to the technical field of side wall sealing strip, specifically is a multilayer composite structure's wind noise reduction side wall sealing strip, including sealing strip, the sealing strip includes upper part, lower part and bonding part, the umbrella -shaped elastic ring is set up in the upper part equidistance, both sides in the lower part are provided with the bending elastic sheet, the sound absorption cotton is set up between the bending elastic sheet in the lower part, through increasing multilayer composite structure, utilize multilayer composite, elastic support, the mode of buffering sound insulation, improve the stability that side wall sealing strip uses, also have the advantage that prolongs actual service life simultaneously, thereby improve use effect.
