Abstract
A sound insulating and absorbing automotive foot mat structure includes at least an upper water-proof layer and a lower sound absorbing layer. The upper water-proof layer is configured as a foaming material, and the lower sound absorbing layer is configured as needle-bonded cotton having a sound absorbing effect. Above the water-proof layer, it can be even added with a blanket and thermoplastic elastomer. Each layer of parts is attached and is formed integrally via a die-cast technology, allowing the mat to be provided with multiple functions of sound insulating, vibration reduction, sound absorbing, water-proofing, light weight and inexpensive manufacturing cost.
