Description
Technical field
Automobile cavity padding field is the utility model is related to, more particularly to a kind of automobile cavity assembled noise reduction barriers.
Background technology
During automobile product development, because body structure designs, unavoidably occur that the connection of some cavitys is in-car
Outside, so as to cause the environmental factors such as dust, steam, air-flow, noise and heat outside car into the car, i.e. vehicle body leakage problem.
In order to solve this problem, the sealing and comfort of automobile are improved, designer devises various sealing structures, outer to prevent
Portion's environmental factor enters the cavity filling technique of interior of body, wherein automobile, is exactly an important application technology.
The cavity filling technique of automobile is generally divided into assembled cavity filling part and pouring-in packing material.Assembled is empty
Chamber filling part is that foaming body is set on skeleton body, is arranged on by assembling mode in cavity, and is promoted by later stage heating
The full cavity of foaming body foaming and intumescing filling, so as to reach the effect of sealing.And pouring-in packing material is by way of injection
Promote the full cavity of foaming body foaming and intumescing filling by the full cavity of expanded material filling of flow-like, and by later stage heating, so as to
Reach the effect of sealing.
Wherein assembled cavity filling part, it has easy for installation, effectively improves production efficiency, and can save and largely send out
The advantages of foam material.But the assembled cavity filling in-between skeleton body of part is thin plate, sound-absorbing effect is not injected into formula cavity
The sound-absorbing effect of packing material is good.
Utility model content
The purpose of this utility model is to provide a kind of good sealing effect, the excellent automobile cavity assembled noise reduction resistance of sound-absorbing effect
Spacing body.
Realizing the technical scheme of the utility model purpose is：The utility model has skeleton body and foaming body；Also include the
One sound-absorbing component；The skeleton body includes preceding surface, rear surface and side；The foaming body is coated on skeleton body along side
On；The preceding surface of the skeleton body is provided with preceding mounting groove；The first sound-absorbing component includes the first connecting plate and is arranged on first
Sound absorbing layer on connecting plate；The shape of first connecting plate is corresponding with the shape of preceding mounting groove；First connecting plate leads to
Cross before fastener is fixedly mounted in mounting groove and sound absorbing layer outwardly.
Meanwhile in addition to the second sound-absorbing component；The second sound-absorbing component includes the second connecting plate and is arranged on the second company
Sound absorbing layer on fishplate bar；The rear surface of the skeleton body is provided with rear mounting groove；The shape of second connecting plate and rear mounting groove
Shape it is corresponding；Second connecting plate be fixedly mounted on by fastener in rear mounting groove and sound absorbing layer outwardly.
Above-mentioned fastener includes elastic latch and the neck coordinated with it.
Elastic latch is equipped with above-mentioned first connecting plate and the second connecting plate；The groove of the preceding mounting groove and rear mounting groove
Neck is equipped with wall.
Neck is equipped with above-mentioned first connecting plate and the second connecting plate；On the cell wall of the preceding mounting groove and rear mounting groove
It is equipped with elastic latch.
Above-mentioned sound absorbing layer is acoustical cotton or abatvoix.
The utility model has positive effect：(1) the utility model sets attractable layer to change assembling on skeleton body
The sound-absorbing effect of formula cavity blocking foaming piece is not as good as the problem of pouring-in cavity filling material sound-absorbing effect；
(2) the first sound-absorbing component and the second sound-absorbing component can use as parts in the utility model, therefore improve
Production efficiency；
(3) the first sound-absorbing component and the second sound-absorbing component are quick and easy for installation in the utility model, while are also convenient for the later stage
Maintenance is changed.
