Description
Technical field
The utility model relates to automobile body accessories fields, and in particular to a kind of automobile gear mudcake of absorbing sound and lowering noise.
Background technique
With the fast development of modern society, urban motor vehicle increases quickly, and automobile has become in our daily lifes
The essential vehicles, but incident city noise pollution phenomenon also becomes increasingly conspicuous.And the generation of city noise
The vehicles are mainly derived from, and the noise that the vehicles generate mainly is exactly automobile noise, automobile noise not only seriously pollutes
The Surroundings in Cities, also very big the health for affecting people, also comes people's lives, work, learning tape serious
Puzzlement.
The noise that automobile is generated in urban conditions mainly based on the noise of enging cabin, its noise generation be with
The difference of engine speed and it is different；And it is normal in effect of the body accessories of the enging cabin two sides gear mudcake on absorbing sound and lowering noise
It is often ignored.EPDM material is mostly used in existing gear mudcake technology, to the decrease of noise functions of automobile substantially without effect.
Utility model content
In view of the above problems, the utility model provides a kind of automobile gear mudcake of absorbing sound and lowering noise.The automobile
Gear mudcake mainly pass through reduce fender, wheel cover metal plate transmitting noise, thus have the function that noise reduction and automobile gear mudcake still
It can keep specious.
The automobile gear mudcake that the utility model provides a kind of absorbing sound and lowering noise includes PP plastic housing, PVC insulation material layer, PVC
Foaming layer, the PP plastic housing include baffle, and PP plastic housing outer surface is equipped with PVC insulation material layer, the PVC sound insulation material
The bed of material is equipped with PVC foam layer, and the PVC foam layer is formed by foam polyvinyl chloride.
Further, the PP plastic housing is made of PP plastics and PP plastic housing is L-shaped.
Further, the bottom edge of the PP plastic housing is zigzag.
Further, the PVC insulation material layer is fixed on PP plastic housing by ultrasonic bonding.
Further, the surface of the baffle is equipped with screw hole, and the arc-shaped face structure of the baffle.
Further, the bottom edge upper surface of the PP plastic housing is glued with reflection type police-man indicating.
The utility model has the beneficial effects that when noise transmission to fender, wheel cover metal plate, the PVC foam that is in contact with it
Layer is able to suppress noise transmission, absorbs the noise of engine；When noise is by PVC foam layer, into highdensity PVC sound insulation material
When the bed of material, PVC insulation material layer can further absorb noise, prevent the transmitting of noise, be finally preferably minimized noise, simultaneously
Driver can be made to find objects in front in advance by using reflection type police-man indicating, safe disposal is taken with the sufficient time to driver
Measure, the generation to avoid traffic accident ensure the security of the lives and property of driver.
Detailed description of the invention
Fig. 1 is that a kind of automobile of absorbing sound and lowering noise of the utility model keeps off the main view of mudcake；
Detailed description of the invention: 1-PP plastic housing, 2-PVC insulation material layer, 3-PVC foaming layer, 4- baffle, 5- screw hole, 6- are reflective
Warning-sign.
Specific embodiment
It elaborates with reference to the accompanying drawing to specific embodiment of the present utility model.
As shown in Figure 1, a kind of automobile of absorbing sound and lowering noise provided by the utility model keeps off mudcake, including PP plastic housing 1, PVC
Insulation material layer 2, PVC foam layer 3, the PP plastic housing 1 include baffle 4, and 1 outer surface of PP plastic housing is equipped with PVC sound insulation
Material layer 2, the PVC insulation material layer 2 are equipped with PVC foaming layer 3, and the PVC foam layer 3 passes through foam polyvinyl chloride
At.
In the present embodiment, the PP plastic housing 1 is made of PP plastics and PP plastic housing 1 is L-shaped.
In the present embodiment, the bottom edge of the PP plastic housing 1 is zigzag.
In the present embodiment, the PVC insulation material layer 2 is fixed on PP plastic housing 1 by ultrasonic bonding.
In the present embodiment, the surface of the baffle 4 is equipped with screw hole 5, and the arc-shaped face structure of the baffle 4.
In the present embodiment, the bottom edge upper surface of the PP plastic housing 1 is glued with reflection type police-man indicating 6.
When it is implemented, General Motors dynamic simulation analysis, specifies the motion profile of automotive suspension, in conjunction with enging cabin week
Fender and metal plate wheel cover 3D data are enclosed, the spatial dimension of confirmation gear mudcake package is adopted by the gear mudcake of dynamic simulation analysis
It is designed with three-dimensional space, so that the range of gear mudcake package is bigger, to achieve the effect that better absorbing sound and lowering noise；Secondly work as and make an uproar
Sound continues through PVC foam layer and PVC insulation material layer, can inhibit the transmitting of noise, play the role of absorbing sound and lowering noise；Specifically
For when noise passes to fender, wheel cover metal plate, the PVC foam layer being in contact with it is able to suppress noise transmission, engine is absorbed
Noise；When noise is by PVC foam layer, into highdensity PVC insulation material layer, the PVC insulation material layer can be into
One step absorbs noise, prevents the transmitting of noise, is finally preferably minimized noise；Furthermore can make to drive by using reflection type police-man indicating
Member has found objects in front in advance, takes safe disposal measure to driver with the sufficient time.Guarantee the life security of driver.
Finally, it is stated that above be only described in detail explanation to the utility model specific embodiment.But this is practical new
Type is not restricted to above description specific embodiment.The equivalent modifications and replace that those skilled in the art carries out the utility model
In generation, is also all among the scope of the utility model.Therefore, the made equalization under the spirit and scope for not departing from the utility model
Transformation and modification, all cover in the scope of the utility model.
