Abstract
The utility model relates to sound insulation expansion slab rubbers outer before a kind of automobile A column, including foaming body, buckle I, buckle II and primer, foaming body is the shape band of polyolefins foamed material, on one end inner plane of foaming body, fix one block of primer, buckle I and buckle II are fixed on other end inner plane, its shape, size, the shape of distance and automobile A column between two buckles, size and car body are adapted, application method is by sound insulation expansion slab rubber outer before A column by being sticked on metal plate surface on the fabrication hole of buckle I and buckle II fixed to sheet metal component before automobile A column and by primer, high-temperature baking is carried out with automobile production later process after the assembly of sound insulation expansion slab rubber, foaming body is expanded foamed, foaming body, buckle I, buckle II adequately fills up exocoel before A column, effect is, accurate positioning, it is easy for installation, soundproof effect is obvious, it produces Product are not easily to fall off, safe and reliable when using, and are worthy to be popularized.
Description
Technical field
The utility model relates to a kind of automobile parts, in particular to outer sound insulation expansion slab rubber and use before a kind of automobile A column
Method.
Background technique
With the progress of auto manufacturing technology, people increasingly pay close attention to the control of passenger car internal car noise and vibration, interior
The controlled level of noise has become the one of the important signs that for measuring passenger car quality.When galloping, automotive front end A column
It is air inlet, generates high-speed flow, high-speed flow and sheet metal component friction generates strong roar, seriously affect driver and passenger
Comfort.Traditional solution is in automobile A column filling sponge or to expand the materials such as film, but these materials are for noise
Control effect it is limited, it is difficult to it is fixed, often fall off and fail, the noise generated in running car can not be effectively reduced.Cause
This how effective closed car A column blocks air-flow to pass through, and becomes the problem of puzzlement Automobile Design developer.
Summary of the invention
Aiming at the problems existing in the prior art, the utility model provides outer sound insulation expansion slab rubber before a kind of automobile A column, dress
Obvious with simple, good airproof performance, soundproof effect, effect of vibration and noise reduction is good, and specific technical solution is, before a kind of automobile A column it is outer every
Sound expansion slab rubber, including foaming body, buckle I, buckle II and primer, it is characterised in that: the foaming body is belt strip, is being sent out
On one end inner plane of foam, fixes one block of primer, is fixed with buckle I and buckle II, shape, ruler on other end inner plane
Distance and the shape of automobile A column, size and car body are adapted between very little, two buckles.
Foaming body, buckle I and buckle II are polyolefins foamed material.
Primer be butyl rubber based on material have adhesiveness sheet material.
The utility model has the technical effect that accurate positioning, easy for installation, soundproof effect is obvious, product using when be not easy to take off
It falls, securely and reliably, is worthy to be popularized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment
It is described further below in conjunction with structure of the attached drawing to the utility model.
As shown in Figure 1 and Figure 2, outer sound insulation expansion slab rubber before a kind of automobile A column, including foaming body 1, I 1-1 of buckle, buckle II
1-2 and primer 2, foaming body 1 are that belt strip fixes one block of primer 2, other end inner plane on one end inner plane of foaming body 1
On be fixed with II 1-2 of I 1-1 of buckle and buckle, between shape, size, two buckles distance and the shape of automobile A column, size with
And car body is adapted.
Foaming body 1, I 1-1 of buckle and II 1-2 of buckle are polyolefins foamed material.
Primer 2 be butyl rubber based on material have adhesiveness sheet material.
In use, by sound insulation expansion slab rubber outer before A column by I 1-1 of buckle and II 1-2 of buckle fixed to metal plate before automobile A column
It is sticked on metal plate surface on the fabrication hole of golden part and by primer 2, with road work after automobile production after sound insulation expansion slab rubber assembly
Sequence carries out high-temperature baking, and foaming body 1, I 1-1 of buckle, II 1-2 of buckle are expanded foamed, adequately fills up exocoel before A column, prevents air-flow
Enter from A column, plays barrier high-speed flow flowing to achieve the purpose that sound insulation and noise reduction.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical solution of the utility model
Limitation in any form, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification,
Equivalent variations and modification, in the range of still falling within the technical solution of the utility model.
