Description
Technical field
The utility model belongs to technical field of automobile parts, and in particular to a kind of new automobile front wall internal sound insulation heat insulating mattress
Assembly.
Background technology
Heat-insulating sound-insulating pad is arranged on automotive interior in automobile front wall, between automobile front wall metal plate and passenger compartment, except must
Outside the structure function wanted, play a part of heat-insulating sound-insulating, outside noise caused by engine and shield heat away to passenger compartment, from
And improve the comfortableness of automobile seating；Heat-insulating sound-insulating pads product in general automobile front wall, is foamed using EVA absorption plus PU
Structure, wherein EVA are that hard formation plays sound-insulating and heat-insulating effect, and PU foaming layers are that porous soft formation plays the effect of sound-absorbing thermal resistance, wherein EVA
Raw material fills the material such as talcum powder more, is that smell is big, cost is high, weight weight the shortcomings that such product.
The content of the invention
The purpose of this utility model is to provide in the new automobile front wall that a kind of structure setting is reasonable and stability in use is good
Sound-heat insulated cushion assembly.
The technical scheme for realizing the utility model purpose is a kind of new automobile front wall internal sound insulation heat insulating mattress assembly, including pad
Plate main body, retaining groove is provided with the edge of the backing plate main body, block button hole is evenly arranged with the backing plate main body
With keep away a depressed part, the backing plate main body includes hard cotton layer, soft cotton layer and plastic film layer, the plastic film layer and is arranged on institute
State between hard cotton layer and soft cotton layer, the hard cotton layer, plastic film layer and soft cotton layer stacks successively and hot melt film is pressed into
Type.
The hard cotton layer is flaggy of the thermoplastic fibre through acupuncture compaction moulding.
The soft cotton layer is fluffy flaggy of the thermoplastic fibre through blending laying net for shaping.
The utility model has positive effect：Structure setting of the present utility model is reasonable, and it uses hard cotton layer and soft
Matter cotton Rotating fields, for EVA material and the PU expanded materials of conventional art, not only with more preferable sound isolating and heat insulating performance,
And processing cost can also be substantially reduced, stability in use is good, strong applicability and practicality is good.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cut-away view of backing plate mainboard of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 and Fig. 2 shows a kind of embodiment of the present utility model, and wherein Fig. 1 is structure of the present utility model
Schematic diagram；Fig. 2 is the cut-away view of backing plate mainboard of the present utility model.
Fig. 1 and Fig. 2, a kind of new automobile front wall internal sound insulation heat insulating mattress assembly, including backing plate main body 1 are seen, in the backing plate
Retaining groove 2 is provided with the edge of main body 1, block button hole 3 is evenly arranged with the backing plate main body 1 and keeps away a depressed part 4,
The backing plate main body 1 includes hard cotton layer 11, soft cotton layer 12 and plastic film layer 13, the plastic film layer and is arranged on the hard
Between cotton layer and soft cotton layer, the hard cotton layer, plastic film layer and soft cotton layer stack successively and hot melt film is molded.Adding
In man-hour, material is stacked in order first, then 180~220 DEG C of bakings in an oven, softened to contained thermoplastic fibre,
Middle plastic foil starts to melt, and is taken out in the mould die cavity for being placed on opening, mold temperature is normal temperature, and is closed rapidly
Mould pressurize, thermoplastic fibre, which cools down, is simultaneously bonded together three, and corner can be cut off because mould carries cutting edge, while matched moulds
Expect, product is taken out after cooling and shaping.
The hard cotton layer is flaggy of the thermoplastic fibre through acupuncture compaction moulding.
The soft cotton layer is fluffy flaggy of the thermoplastic fibre through blending laying net for shaping.
In the present embodiment, the thickness of hard cotton layer is 10mm, grammes per square metre 1000g/m2；The material of plastic film layer be PE or
EVA plastic sheetings, thickness 0.2mm；The thickness of soft cotton layer is 20mm, grammes per square metre 1500g/m2。
Structure setting of the present utility model is reasonable, and it uses hard cotton layer and soft cotton Rotating fields, compared to conventional art
EVA material is with that for PU expanded materials, not only with more preferable sound isolating and heat insulating performance, and can also substantially reduce and be processed into
This, stability in use is good, strong applicability and practicality is good.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model is extended out and still fall within this practicality
New protection domain.
