Primary symbols explanation:
Specific embodiment
The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model,
It states.The preferred embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms in fact
It is existing, however it is not limited to embodiment described herein.On the contrary, the purpose for providing this embodiment is the public affairs made to the utility model
It is more thorough and comprehensive to open content.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes
Any and all combinations of one or more related listed items.
Sound insulation carpet noise reduction, damping effect now on the market is poor, influences the comfort level of people to a certain extent.
In order to solve this technical problem, the first embodiment of the utility model proposes a kind of sound insulation carpet, please refers to figure
1, for the sound insulation carpet that the utility model embodiment proposes, including superficial layer 1, elastic layer 3, the first puigging 4, puigging 6
With the second puigging 8.
For above-mentioned puigging 6, which is respectively equipped with the first puigging 4 and the second puigging 8,
One puigging, 4 upper surface is uniformly provided with lower convexity 5, and the lower convexity is not in contact with each other between any two, convex under first puigging
It plays 5 to connect by binder with the bonding of sound absorbing layer 6,4 lower surface of the first puigging is formed with 6 lower surface of sound absorbing layer
First space layer 10 is uniformly provided with upper raised 7 in 8 upper surface of the second puigging, and the upper protrusion is not in contact with each other between any two, institute
State on the second puigging protrusion 7 and connected by binder with being bonded with sound absorbing layer 6,8 upper surface of the second puigging with it is described
6 lower surface of sound absorbing layer forms second space layer 11.In addition, being formed in 8 lower surface of the second puigging blade coating EPDM rubber particle anti-
Slip layer 9.
For the first above-mentioned puigging 4,4 upper surface even adhesion of the first puigging has chondritic elastomer 2, institute
It states elastomer 2 to be not in contact with each other between any two, 2 upper surface of elastomer is connected by binder with the bonding of 1 lower surface of superficial layer.
In practical applications, since elastomer 2 has good elasticity, when power acts on carpet, deformation occurs for elastomer 2, rises
To the effect of buffering, the damping effect of the sound insulation carpet is improved.
In the present embodiment, 6 upper surface of puigging and 4 lower surface of the first sound absorbing layer form the first space layer 10, under puigging 6
Surface and 8 upper surface of the second puigging form second space layer 11.Since the sound absorbing layer 6 is porous structure layer, in porous knot
Structure layer is respectively kept with space layer up and down, improves low, intermediate frequency acoustic absorptivity, enhances the noise reduction effect of the sound insulation carpet.
In the present embodiment, anti-slip layer 9 is scratched by EPDM rubber particle and is formed, due to EPDM rubber particle surface multi-panel not
Systematicness, 9 lower surface of anti-slip layer form concaveconvex structure, increase frictional force between the sound insulation carpet and car floor, solve
In the prior art, the problem of car carpeting can not sufficiently be bonded with automotive floor panel.
The utility model proposes sound insulation carpet include superficial layer 1, elastic layer 2, the first puigging 4, sound absorbing layer 6 and second
Puigging 8.In practical applications, bottom of car noise reaches superficial layer 1 by anti-slip layer 9.Sound wave is reaching the second puigging 8
When, since the second puigging 8 is made of EVA rubber, the material can effectively reflected acoustic wave, reduce penetrating for sound wave.Work as sound
When wave reaches sound absorbing layer 6, since sound absorbing layer 6 is porous material, the first space layer 10 is formed by with the first puigging 4 and with the
Two puiggings are formed by the acoustic absorptivity that second space layer 11 improves carpet, to further weaken the energy of sound.?
After sound wave reaches the first puigging 4, the first puigging 4 reflects sound wave again, to reach the effect for reducing internal car noise
Fruit.Furthermore the elastomer of elastic layer 3 makes the sound insulation carpet have good elasticity, and the concaveconvex structure of 9 lower surface of anti-slip layer increases
The big frictional force of the sound insulation carpet and car floor, so that the sound insulation carpet has the function that noise reduction, anti-skidding, damping,
Meet practical application request.
The second embodiment of the utility model also proposes a kind of automobile, including car floor, sets on the car floor
There is sound insulation carpet, which is the sound insulation carpet in first embodiment, can improve automobile using the automobile of the sound insulation carpet
Whole NVH performance.
The utility model several embodiments above described embodiment only expresses, the description thereof is more specific and detailed, but
It should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
