Description
Technical field
The utility model is related to field of material technology, and in particular to melamine foam sound insulating pad in a kind of automobile.
Background technology
The sound insulating pad of automobile is mainly used in the heat insulation sound absorbent between automobile cab and engine.
Publication No. CN203958031U Chinese patent literature discloses a kind of body front wall sound insulating pad, it include every
Sound pad and lower sound insulating pad, the upper sound insulating pad are overlapped with the lower sound insulating pad, and the upper sound insulating pad is taken with the lower sound insulating pad
The place of connecing is provided with noise reduction cavity.The body front wall sound insulating pad that the patent is provided designs the sound insulating pad split of original integral type, on every
Sound pad and the difference compression molding of lower sound insulating pad, can be achieved straight upper or directly lower withdrawing pattern mode, above sound insulating pad and lower sound insulation during installation
Pad can be also respectively mounted, and the installation bolt on vehicle body sheet metal is easily engaged with positioning hole, therefore the edge of positioning hole need not
Flanging processing is carried out, production and installation are all very convenient, and by the setting of upper sound insulating pad and lower sound insulating pad lap-joint noise reduction cavity,
It effectively prevent local noise at the caused split of split design excessive.
Publication No. CN203358492U Chinese patent literature discloses a kind of automotive hood sound insulating pad, including every
Sound pad body, the sound insulation pad body is provided with cage bar, and the periphery of the sound insulation pad body is provided with reinforcement, and the sound insulating pad
The back side of body is oriented to groove provided with pipeline.The utility model is not increasing buckle quantity, on the premise of not changing material technology,
By setting up reinforcement in the periphery of sound insulation pad body, it is ensured that the rigidity and intensity of the overall especially boundary of sound insulating pad, keep away
There is collapse phenomenon in the corner or middle part for having exempted from hood sound insulating pad；At the sound insulation pad body back side, increase pipeline is oriented to recessed
Groove so that hood sound insulating pad band pipeline guiding constraint function, it is to avoid between washing pipeline and hood sound insulating pad
Interfere with each other, while ensureing that washing pipeline and hood sound insulating pad fully realize respective function, improve washing pipeline
By property, and do not influence the front appearance of hood sound insulating pad；The patent structure is simple, practical.
Utility model content
The purpose of this utility model is to provide melamine foam sound insulating pad in a kind of automobile, the sound insulation that the utility model is provided
Light weight, high temperature resistant are padded, and soundproof effect is good.
To achieve the above object, the utility model provides melamine in melamine foam sound insulating pad in a kind of automobile, the automobile
Foam sound insulating pad from top to bottom includes upper damping sheet, melamine foam layer and lower damping sheet, the upper damping sheet, melamine bubble successively
Foam layer is fixedly connected by glue layer between any two with lower damping sheet.
Preferably, melamine foam sound insulating pad has from top to bottom also penetrated through metal rivet in the automobile.
Preferably, it is provided with resistance to height between the metal rivet and the upper damping sheet, melamine foam layer and lower damping sheet
Warm rubber ring.
Preferably, the porosity of the melamine foam layer is 4-12%.
Preferably, the thickness of the upper damping sheet and lower damping sheet is respectively 0.5-2 centimetres, the thickness of the melamine foam layer
Spend for 2-10 centimetres.
The utility model has the following advantages that：
The sound insulating pad acoustically effective that the utility model is provided is more than 2 times of common material, and fire resistance is good, Ultralight
Deng market prospects are huge, and the current material is in the entrucking test of Duo Jia automobile factorys.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of sound insulating pad that the utility model is provided.
Fig. 2 is a kind of structural representation of embodiment of sound insulating pad that the utility model is provided.
Embodiment
Following examples are used to illustrate the utility model, but are not limited to scope of the present utility model.
As shown in figure 1, the utility model provide in melamine foam sound insulating pad in a kind of automobile, the automobile melamine foam every
Sound pad from top to bottom includes upper damping sheet 1, melamine foam layer 2 and lower damping sheet 3, the upper damping sheet 1, melamine foam successively
Layer 2 is fixedly connected by glue layer 4 between any two with lower damping sheet 3.The sound insulating pad acoustically effective that the utility model is provided is general
More than 2 times of logical material, fire resistance is good, Ultralight etc., and market prospects are huge, and the current material is in the entrucking of Duo Jia automobile factorys
Test.
Because external engine temperature is higher, in order to prevent sound insulating pad from falling apart, as shown in Fig. 2 a kind of embodiment,
