Description
Technical field
A kind of auto parts machinery is the utility model is related to, more particularly to a kind of vehicle side exocoel sound insulating seal device.
Background technology
In recent years, sound insulation, the expandable material of vibration damping play a part of increasing, such as vapour in auto NVH field
When car is run at high speed, the bypass cavity of vehicle body can produce high velocity air when running at high speed, and can be brought strongly to passenger and driver
Noise and vibration.In order to solve this problem, various expanded materials have been widely used in filling bypass cavity.Mesh
It is preceding using it is more be vinyl（Such as EVA）Expanded material, it has very light weight, that adhesive force is good, acoustically effective is good etc. is excellent
Point.This kind of material is assemblied in the cavity of vehicle body, and bodywork cavity is filled after expansion, plays sound insulation, the purpose of vibration damping.But for car
The narrow gusset exocoel of body, traditional handicraft are bonded using rubber expanded material, but it easily comes off, smell is big, VOC content
It is high, it is therefore necessary to find new method and sound insulating seal is carried out to gusset exocoel.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of vehicle side exocoel sound insulating seal device, modeling
The installation of material buckle does not interfere with the foaming effect of foam sheet, and the device assembling process is simple, accurate positioning, due to sheet metal
Play a supporting role, it is difficult for drop-off after foam sheet foaming, while the smell of foam sheet and VOC content are relatively low, meet vapour
Car environmental requirement.
To achieve the above object, used technical scheme solution is the utility model：A kind of vehicle side exocoel sound insulation is close
Seal apparatus, it is characterised in that：Including plastic buckle, foam sheet, sheet metal；It is strip-shaped blade among the foam sheet, strip
Piece both ends are strip inclined tab, and two strip inclined tab difference are outward-dipping, and two end faces are interval with foam sheet strip-shaped blade
For semicircular projection, a fixing hole is respectively equipped with two crownings；
The structure of the sheet metal is identical with the structure of foam sheet；
Two panels foam sheet is superimposed, and is sheet metal, two panels foam sheet and piece of metal piece between foam sheet
An entirety is formed, in two fixing holes of two panels foam sheet and piece of metal piece, is respectively equipped with a plastic buckle.
The utility model has the advantages that：The device is easy for installation, accurate positioning, difficult for drop-off, smell is low, VOC content compared with
It is low, soundproof effect is good.Device manufacture craft is simple, saves material, low manufacture cost, reliable using process safety, meets vapour
Car environmental requirement.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model.
In figure：1st, plastic buckle, 2, foam sheet, 3, sheet metal.
Embodiment
Structure of the present utility model is described further below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of vehicle side exocoel sound insulating seal device, including plastic buckle 1, foam sheet 2, metal
Piece 3.
It is strip-shaped blade among foam sheet 2, strip-shaped blade both ends are strip inclined tab, and two strip inclined tab difference are outward-dipping,
In the strip-shaped blade among foam sheet 2, it is semicircular raised 2-1 to be interval with two end faces, semicircular convex at two
Rise and be respectively equipped with a fixing hole 2-1-1 on 2-1 faces.
The structure of sheet metal 3 is identical with the structure of foam sheet 2.
Two panels foam sheet 2 is superimposed, is sheet metal 3 between two panels foam sheet 2, the He of two panels foam sheet 2
Piece of metal piece 3 forms an entirety, in two fixing hole 2-1-1 of foam sheet 2 and piece of metal piece 3, is respectively equipped with
One plastic buckle 1.
In use, the present apparatus is arranged on vehicle side exocoel sheet metal component, two plastic buckles 1 are each passed through automobile side
Two fixing hole 2-1-1 of exocoel sound insulating seal device are enclosed, are screwed onto in the fabrication hole on vehicle side exocoel sheet metal component, incite somebody to action this
Device sets and is fixed on vehicle side exocoel sheet metal component.After device assembling, high temperature baking is carried out with automobile production later process
Roasting, foam sheet 2 is expanded foamed, is sufficient filling with vehicle side exocoel, plays the flowing of barrier high velocity air so as to reach sound insulation drop
The purpose made an uproar.
The device is applied to narrow vehicle side exocoel.
Plastic buckle 1 is resistant to elevated temperatures nylon material, you can with for connecting sheet metal and foam sheet, realize again by
Device is fixed on body side wall exocoel sheet metal component, solves the problems, such as that expanded material is difficult to fix.
Sheet metal is steel plate or aluminium sheet material.
Foam sheet 2 is that maleic anhydride modified polyvinyls or copolymer add foaming agent, crosslinking agent, filler etc.
The high temperature expandable material mixed, such material have good bonding force in case of heating with sheet metal, process
When can be shaped to sheet material by the mode such as being molded, extruding, then cut into required shape.
