In modern automobiles, carpets are installed on the inner bottom wall of the automobile for attractive appearance and convenient cleaning and maintenance, the automobile carpets generally consist of carpets and carpet sound insulation pads, and some automobile carpets and automobile carpet sound insulation pads are separately supplied and paved together during the whole automobile installation, but the assembly mode increases the subsequent process difficulty of the total assembly line, and the two products have the problem of size matching.
In order to solve the problem, the carpet and the carpet sound insulation pad are assembled together before being paved, and then are paved, but most manufacturers bond the carpet and the sound insulation pad by using glue when the carpet and the carpet sound insulation pad are assembled in advance, and then re-press the tooling after bonding, so that the process is high in cost, and the bonded carpet has peculiar smell and more harmful components in peculiar smell gas, so that the health of a human body can be endangered. Meanwhile, the existing automobile carpet is large in weight and cannot meet the light-weight design requirement of the whole automobile.
Moreover, the present invention has been made in view of the above circumstances before assembly.
