Embodiment Construction

[0023] Please refer to figure 1 , figure 2 As shown, the present invention takes the manufacture of a car sound-proof and sound-absorbing foot mat as an example, which at least consists of a waterproof layer of foam material 20 and a sound-absorbing layer 30 of needle-ginned cotton with sound-absorbing effects. The waterproof layer is set on the upper layer, and the sound-absorbing layer is set on the lower layer. The components of each layer are laminated and formed integrally by molding technology, so that the cushion body has multiple functions of sound insulation, shock absorption, sound absorption, waterproof, light weight and low manufacturing cost. Even blankets and thermoplastic elastomer TPE materials can be added on the waterproof layer.

[0024] In the embodiment of the present invention, the foot pad structure is composed of three-layer components such as a blanket 10 on the top layer, a foam material 20 on the middle layer, and a sound-absorbing layer 30 on the ...

Abstract

The invention relates to a sound insulating and absorbing mat structure of an automobile, at least comprising a waterproof layer positioned at the upper layer and a sound-absorbing layer positioned at the lower layer. The waterproof layer at the upper layer is made of foam materials, and the sound-absorbing layer at the lower layer is made of needle punching cotton with sound-absorbing effect; the waterproof layer can be even additionally provided with materials of blankets and thermoplastic elastomers (TPE); and components of each layer are jointed and formed together by a mould pressing technology. The mat has a plurality of effects of sound insulation, cushion, shock absorption, sound absorption, water resistance, light weight and low manufacture cost.

Description

technical field [0001] The present invention relates to a sound-insulating and sound-absorbing tread mat structure for automobiles, especially the automobile tread mats and interior molded carpets formed by such a structure. When the tread mats are made, they can be placed on the interior molding carpets for people to step on. It will not slip, and at the same time, it can collect the mud and sand stained on the soles without dirtying the molded carpet in the car. Regardless of whether it is made into a foot mat or a molded carpet in the car, the design of its own material can effectively block the chassis. Noise can enter the car, and it has the functions of waterproof, sound absorption, and easy molding. Background technique [0002] According to general automobiles, carpets are usually laid on the interior floor of the car when it is manufactured. This carpet has a good texture and is expensive, so it has a decorative effect and enhances the beautiful texture of the inter...
