Description
Technical field
The utility model relates to Automobile Products technical field, is specifically related to a kind of double-decker sound-absorbing carpet.
Background technology
Automobile in the process of moving wheel rolls on the ground, car all can send noise with windage and engine operation etc.Thus cause environment inside car sound comparatively large, affect car comfort inside.
Existing automobile acoustical absorption carpet adopts the thickness increasing sound-absorbing carpet to improve the effect of sound-absorbing usually.But thickness adds and causes floor area in the process of carrying or receive comparatively large, is inconvenient to carry and receive.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model be to provide a kind of rational in infrastructure, be convenient to carry and the double-decker sound-absorbing carpet of storage.
For achieving the above object, the utility model adopts following technical scheme:
A kind of double-decker sound-absorbing carpet, comprises the first sound absorbing layer, adhesive layer and the second sound absorbing layer that are cascading from the bottom up, and described adhesive layer is used for the first sound absorbing layer to be fixedly connected with the second sound absorbing layer;
The upper surface compartment of terrain of described first sound absorbing layer is provided with some projections, is formed with gully between adjacent projection; The lower surface of described first sound absorbing layer is provided with the sound-absorption hole equal with described number of slugs; The below correspondence of each projection forms a sound-absorption hole;
The lower surface of described second sound absorbing layer offers some Baltimore grooves and/or concave hole; Weighting material is filled with in described Baltimore groove or concave hole.
Preferably, the surface of each projection is curved.
Preferably, the perisporium of described Baltimore groove or concave hole is all curved; The periphery of described Baltimore groove or concave hole is formed with fin.
Preferably, described first sound absorbing layer is that XPE expanded material is made; Described second sound absorbing layer can be PET and makes.
Preferably, described weighting material is sponge or silica gel.
The beneficial effects of the utility model:
Double-decker sound-absorbing carpet of the present utility model only comprises the first sound absorbing layer, adhesive layer and the second sound absorbing layer that are cascading from the bottom up; Then some Baltimore grooves and/or concave hole is offered at the lower surface of described second sound absorbing layer; Weighting material is filled with in described Baltimore groove or concave hole.Thus achieve and improve sound-absorbing effect of the present utility model when ensureing that sound-absorbing carpet thickness is certain.Additionally by described first sound absorbing layer initial absorption carried out to sound and by the second sound absorbing layer, double absorption carried out to sound, the effect of sound-absorbing can be improved by actv..
Accompanying drawing explanation
Fig. 1 is the overall schematic of a kind of double-decker sound-absorbing carpet in embodiment of the present utility model;
Fig. 2 is the part sectional view of a kind of double-decker sound-absorbing carpet in embodiment of the present utility model.
In figure: 1, the first sound absorbing layer; 11, projection; 12, gully; 13, sound-absorption hole; 2, adhesive layer; 3, the second sound absorbing layer; 31, concave hole; 32, weighting material; 33, fin.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
With reference to Fig. 1 and Fig. 2, a kind of double-decker sound-absorbing carpet described in the present embodiment, comprises the first sound absorbing layer 1, adhesive layer 2 and the second sound absorbing layer 3 that are cascading from the bottom up.Described adhesive layer 2 is glue.Described adhesive layer 2 is for being fixedly connected with the first sound absorbing layer 1 with the second sound absorbing layer 3.
The upper surface compartment of terrain of described first sound absorbing layer 1 is provided with some projections 11, is formed with gully 12 between adjacent projection 11.The lower surface of described first sound absorbing layer 1 is provided with the sound-absorption hole 13 equal with described projection 11 quantity.The below correspondence of each projection 11 forms a sound-absorption hole 13.The surface of each projection 11 is curved.Described sound-absorption hole 13 can effectively by motor tire or start the noise sent to carry out initial absorption.
Described gully 12 can improve the area of contact of the first sound absorbing layer 1 and gluing 2 layers effectively, thus improves the stability between adhesive layer 2 and the first sound absorbing layer 1.Additionally by the absorption number voice that this gully 12 also can be appropriate.
The lower surface of described second sound absorbing layer 3 offers some Baltimore grooves and/or concave hole 31.The weighting material such as sponge or rubber 32 is filled with in described Baltimore groove or concave hole 31.This second sound absorbing layer 3, for carrying out double absorption to shock double-decker sound-absorbing carpet sound, realizes better sound-absorbing effect.
The periphery of described Baltimore groove or concave hole 31 is formed with fin 33.Coordinated with Baltimore groove and/or concave hole 31 by fin 33, can improve sound-absorbing area by actv., when making sound clash into double-decker sound-absorbing carpet of the present utility model, sound energy actv. is absorbed.And in Baltimore groove and/or concave hole 31, be filled with weighting material 32, the sound clashing into this double-decker sound-absorbing carpet can be absorbed actv. completely, prevent the phenomenon that sound is ejected.
The perisporium of described Baltimore groove or concave hole 31 is all curved.When sound enters Baltimore groove or concave hole 31, sound will by the perisporium reflecting focal of arc together, thus facilitate the carrying out of weighting material 32 pairs of sound to absorb completely.
Described first sound absorbing layer 1 can be XPE expanded material (processes for chemically crosslinked polyethylene expanded material) and makes.Described second sound absorbing layer 3 can be PET (polyethylene terephthalate) and makes.
The utility model by offering Baltimore groove or concave hole 31 carrys out the weighting material such as filling sponge or silica gel 32 on the second sound absorbing layer 3, realize under the condition not increasing double-decker sound-absorbing carpet thickness, improve sound-absorbing effect of the present utility model, so double-decker sound-absorbing carpet of the present utility model not only sound-absorbing effect good and also be convenient to storage with carry.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
