Description
Technical field
The utility model relates to automotive field, particularly a kind of automobile front wall sound-isolation structure and automobile.
Background technology
At present, the space in automobile is comparatively closed, also very strict to the noise control in automobile, front wall sound-isolation pad is as the important spare part of automobile acoustical absorption sound insulation, its acoustic efficiency is for noise important role in control car, but the front wall sound-isolation pad weight that often performance is better is large, and cost is high.
Utility model content
The utility model provides a kind of automobile front wall sound-isolation structure and automobile, its objective is the soundproof effect in order to promote automobile front wall.
In order to achieve the above object, embodiment of the present utility model provides a kind of automobile front wall sound-isolation structure, is arranged between automobile dash board and automotive trim panel, comprises:
First sound-absorbing pad, the side of described first sound-absorbing pad is provided with the first adhesive structure, and described first sound-absorbing pad fits tightly on described automobile dash board by described first adhesive structure;
Sound insulating pad, the side of described sound insulating pad and the opposite side of described first sound-absorbing pad fit tightly;
Second sound-absorbing pad, the side of described second sound-absorbing pad and the opposite side of described sound insulating pad fit tightly, the opposite side of described second sound-absorbing pad is provided with the second adhesive structure, and described second sound-absorbing pad is fitted tightly by described second adhesive structure and described automotive trim panel.
Wherein, the material of described first sound-absorbing pad and described second sound-absorbing pad is cotton felt material.
Wherein, the material of described sound insulating pad is elastomeric material.
Wherein, described sound insulating pad is arranged between described first sound-absorbing pad and described second sound-absorbing pad, and described sound insulating pad and described first sound-absorbing pad and described second sound-absorbing pad are structure as a whole.
Of the present utility modelly embodiment still provides a kind of automobile, comprise the automobile front wall sound-isolation structure described in above-described embodiment.
Such scheme of the present utility model has following beneficial effect:
Automobile front wall sound-isolation structure provided by the utility model and auto sound, sound absorption qualities are good, lightweight, and cost is lower, can according to noise in car, the adjustment of car external noise size for the control of noise in noise in car and car.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model soundproof effect schematic diagram.
[description of reference numerals]
1-first sound-absorbing pad; 2-sound insulating pad; 3-second sound-absorbing pad.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model needs the problem controlled for the noise level in existing automobile, provide a kind of automobile front wall sound-isolation structure and automobile.
As shown in Figure 1, embodiment of the present utility model provides a kind of automobile front wall sound-isolation structure, be arranged between automobile dash board and automotive trim panel, comprise: the first sound-absorbing pad 1, the side of described first sound-absorbing pad 1 is provided with the first adhesive structure, and described first sound-absorbing pad 1 fits tightly on described automobile dash board by described first adhesive structure; Sound insulating pad 2, the side of described sound insulating pad 2 and the opposite side of described first sound-absorbing pad 1 fit tightly; Second sound-absorbing pad 3, the described side of the second sound-absorbing pad 3 and the opposite side of described sound insulating pad 2 fit tightly, the opposite side of described second sound-absorbing pad 3 is provided with the second adhesive structure, and described second sound-absorbing pad 3 is fitted tightly by described second adhesive structure and described automotive trim panel.
Automobile front wall sound-isolation structure provided by the utility model sound insulation, sound absorption qualities are good, lightweight, and cost is lower, can according to noise in car, the adjustment of car external noise size for the control of noise in noise in car and car.
Wherein, the material of described first sound-absorbing pad 1 and described second sound-absorbing pad 3 is cotton felt material.
Wherein, the material of described sound insulating pad 2 is elastomeric material.
The first sound-absorbing pad 1 described in above-described embodiment of the present utility model and the material of the second sound-absorbing pad 3 are cotton felt material, the thicker but leakiness of structure, are attract part; The material of described sound insulating pad 2 is elastomeric material, and structure is thin and closely knit, is sound insulation part; For sound insulation value, mainly runner wagon external noise imports in car, and sound is propagated by medium, and sound has decay and reflection when changing propagation medium, acoustic construction described in the utility model is by the design of 3 layer materials, and can realize 3 deadenings, sound insulation value is superior.
Wherein, described sound insulating pad 2 is arranged between described first sound-absorbing pad 1 and described second sound-absorbing pad 3, and described sound insulating pad 2 is structure as a whole with described first sound-absorbing pad 1 and described second sound-absorbing pad 3.
As shown in Figure 2, sound insulation principle of the present utility model is: for car external noise, has attenuation of the first kind by described first sound-absorbing pad 1; Change medium by described sound insulating pad 2, also there is while decay the effect of reflect noise; Third time decay is carried out by described second sound-absorbing pad 3; Identical for noise principle in car, simultaneously front wall acoustic construction described in the utility model can adjust when mould is constant two-layer sound absorption materials thickness, thus adjustment acoustic construction is for the control of noise in car and car external noise, adjust according to actual conditions, thus make car load noiseproof feature reach best.
Of the present utility modelly embodiment still provides a kind of automobile, comprise the automobile front wall sound-isolation structure described in above-described embodiment.
Acoustic construction described in the utility model and automobile pass through the design of 3 layer materials, and can realize 3 deadenings, sound insulation value is superior; Can adjust when mould is constant simultaneously two-layer sound absorption materials thickness, thus adjustment acoustic construction is for the control of noise in car and car external noise, adjusts, thus make car load noiseproof feature reach best according to actual conditions.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
