Abstract
The utility model discloses a kind of automobile acoustical absorption pad with hollow structure, relate to automatic foot-mat field, described sound-absorbing pad comprises pet layer and nonwoven layer, pet layer and nonwoven layer are concave structure, pet layer to be positioned at above nonwoven layer and with nonwoven layer axisymmetricly, be provided with interlayer, regenerated fibre carpet veneer, lower interlayer between pet layer and nonwoven layer, wherein go up interlayer inside and be filled with and inhale ripple sponge, lower interlayer inside is air, has also inlayed mass of glass fibers below described nonwoven layer.In the utility model, the concave structure of pet layer and nonwoven layer produces the hollow structure of a relative closure, the suction ripple sponge of upper interlayer, the regenerated fibre felt of regenerated fibre carpet veneer and the nonwoven fabrics of nonwoven layer all have good sound-absorbing effect, the air of lower interlayer inside has blocked the approach of noise transmission further, makes whole sound-absorbing pad have very excellent sound absorption.
Description
Technical field
The utility model relates to automatic foot-mat field, specifically refers to a kind of automobile acoustical absorption pad with hollow structure.
Background technology
Existing automatic foot-mat generally includes rubber mat, carpet foot pad, PVC foot pad, plastic cement foot pad etc., also carpet is had to add the combined foot pad of the bilayers such as PVC or multilayer, the object of compound is normally from double feature of getting two or more materials itself, such as carpet adds the double-deck foot pad of PVC, the feature that mainly existing carpet layer is soft, warming, have again layer of PVC waterproof, firmly, the feature of easy cleaning.
But existing single or multiple lift automatic foot-mat, in use do not have the function of sound-absorbing, or sound-absorbing effect is very poor, or while sound-absorbing, sacrifice comfort when sound-absorbing pad uses.When namely cannot effectively reduce automobile runs at the bottom of car by the noise that automobile floor transmission comes up, especially when automobile high-speed or idling, this noise is particularly evident.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides a kind of automobile acoustical absorption pad with hollow structure.
To achieve these goals, technical solution adopted in the utility model is: a kind of automobile acoustical absorption pad with hollow structure, described sound-absorbing pad comprises pet layer and nonwoven layer, pet layer and nonwoven layer are concave structure, pet layer to be positioned at above nonwoven layer and with nonwoven layer axisymmetricly, interlayer, regenerated fibre carpet veneer, lower interlayer is provided with between pet layer and nonwoven layer, wherein go up interlayer for inhaling ripple sponge, lower interlayer is air, has also inlayed mass of glass fibers below described nonwoven layer.
As the improvement of technique scheme, each embedded one piece of polyester cotton of the right and left above described pet layer.
As the improvement of technique scheme, described mass of glass fibers is flat semicircle, and this mass of glass fibers left and right is adjacent and be covered with the lower surface of nonwoven layer.
Compared with prior art, the beneficial effects of the utility model are as follows:
In the utility model, the concave structure of pet layer and nonwoven layer produces the hollow structure of a relative closure, the suction ripple sponge of upper interlayer, the regenerated fibre felt of regenerated fibre carpet veneer and the nonwoven fabrics of nonwoven layer all have good sound-absorbing effect, the air of lower interlayer inside has blocked the approach of noise transmission further, whole sound-absorbing pad is made to have very excellent sound absorption, in addition, the mass of glass fibers under nonwoven layer also has heat insulation, the effect such as fire-resistant, tension.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the automobile acoustical absorption pad of hollow structure.
In figure, 1-PET layer, 2-nonwoven layer, the upper interlayer of 3-, 4-regenerated fibre carpet veneer, interlayer under 5-, 11-polyester cotton, 12-inhales ripple sponge, 13-mass of glass fibers.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of automobile acoustical absorption pad with hollow structure, this sound-absorbing pad comprises pet layer 1 and nonwoven layer 2, pet layer 1 and nonwoven layer 2 are concave structure, pet layer 1 to be positioned at above nonwoven layer 2 and with nonwoven layer 2 axisymmetricly, be provided with interlayer 3, regenerated fibre carpet veneer 4, lower interlayer 5 between pet layer 1 and nonwoven layer 2, wherein go up interlayer 3 inside and be filled with and inhale ripple sponge 12, lower interlayer 5 inside is air, and nonwoven layer 2 has also inlayed mass of glass fibers 13 below.
The main component of pet layer 1 is polyethylene terephthalate, has the high and low temperature resistance that impact strength is high and excellent; Nonwoven layer 2 has protection against the tide, ventilative, pliable and tough, light weight, the characteristic such as not combustion-supporting; Regenerated fibre carpet veneer 4 can increase the hardness of sound-absorbing pad, also has certain sound-absorbing effect simultaneously; Inhale ripple sponge 12 due to its cellular inner structure, there is very strong suction ripple, sound absorbing power, the noise up to more than 70% can be reduced within the specific limits.
Pet layer 1 is each embedded one piece of polyester cotton 11 of the right and left above, not only can improve the elasticity of pet layer 1, and have the effect of sound-absorbing vibrationproof; Mass of glass fibers 13 is flat semicircle, and this mass of glass fibers about 13 is adjacent and be covered with the lower surface of nonwoven layer 2, has heat insulation, the effect such as fire-resistant, tension.
In this sound-absorbing pad, the concave structure of pet layer 1 and nonwoven layer 2 produces the hollow structure of a relative closure, the suction ripple sponge 12 of upper interlayer 3, the regenerated fibre felt of regenerated fibre carpet veneer 4 and the nonwoven fabrics of nonwoven layer 2 all have good sound-absorbing effect, the air of lower interlayer 5 inside has blocked the approach of noise transmission further, makes whole sound-absorbing pad have very excellent sound absorption.In addition, the mass of glass fibers 13 under nonwoven layer 2 also has heat insulation, the effect such as fire-resistant, tension.
