Document Type and Number:

WIPO Patent Application WO/2021/254259

Kind Code:

A1

Abstract:

Provided is a motor vehicle fender lining, relating to the technical field of auto parts, and comprising a fender lining inner housing (110), a heating layer (120), a heat insulation layer (130), a sound absorption layer (140), and a fender lining outer housing (150). The heating layer (120) is fixed on the fender lining inner housing (110); the heat insulation layer (130) is fixed on the heating layer (120); the sound absorption layer (140) is fixedly installed on the heat insulation layer (130); the fender lining outer housing (150) is fixed on the sound absorption layer (140); a graphene heating film (121) is provided in the heating layer (120); the graphene heating film (121) is electrically connected to a power interface (122); the power interface (122) is fixedly installed on the fender lining outer housing (150); the sound absorption layer (140) comprises a glass fiber sound absorption cotton layer (141) and a butyl rubber layer (142); the glass fiber sound absorption cotton layer (141) abuts against the heat insulation layer (130); and the butyl rubber layer (142) abuts against the fender lining outer housing (150). The structure can achieve functions of noise reduction, vibration damping, and sound absorption.
