Abstract
The utility model relates to an automobile silencer, comprising a buckle, a plastic bracket and foam material. The plastic bracket is connected with the foam material, one end of the plastic bracket is at least provided with a buckle, and the plastic bracket and the foam material are fixed on an automobile body sheet metal part through the buckle. After high-temperature roasting of an electrophoresis process, the foam material expands and foams to fill the cavity of the automobile body so that the purposes of preventing and eliminating air and reducing noise are achieved. The automobile silencer has the advantages of accurate location, convenient installation, obvious silencing effect and the like. The use level of the foam material is low, and the density of the foam material after high-temperature expansion is very low, thereby the weight of the automobile can be effectively lightened, and the material cost is saved. The automobile silencer can effectively reduce the noise generated during the travel of the automobile, thereby having wide market prospect and being worthy of generalization.
Description
Technical field
The utility model relates to vehicular spare parts, particularly relates to a kind of automobile sound arrester.
Background technology
Along with the progress of auto manufacturing technology, people more and more are concerned about the noise problem in the running car.When galloping, can produce high velocity air in the bodywork cavity (, precedingly enclose, gusset, threshold etc.) as A, B, C post, high velocity air and the strong roar of sheet metal component friction generation have a strong impact on driver and passenger's comfort.Traditional solution is at materials such as inner filling sponge of bodywork cavity or expansion films, but these materials are limited for the Noise Control effect, especially for bigger bodywork cavity, these materials are difficult to be full of fully cavity, therefore air flows can not be effectively intercepted, also just the noise that produces in the running car can not be effectively reduced.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is in order to solve the deficiency of above-mentioned prior art, to provide a kind of especially and can effectively reduce the automobile sound arrester that produces noise problem in the running car.
The technical scheme that the utility model is taked for achieving the above object is: a kind of automobile sound arrester, it is characterized in that: comprise buckle, plastic stent and expanded material, described plastic stent is connected with expanded material, one end of plastic stent is provided with a buckle at least, and by buckle plastic stent and expanded material is fixed on the auto body sheet metal component.
The beneficial effect that the utility model produced is: the automobile sound arrester has accurate positioning, easy for installation, advantage such as erasure effect is obvious.Because the expanded material materials are few, and the density after the high temperature expansion is very low, can effectively alleviate vehicle weight, simultaneously the economical with materials cost.Because this device can effectively reduce the noise problem that produces in the running car, therefore have vast market prospect, be worthy to be popularized.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of automobile sound arrester comprises buckle 1, plastic stent 2 and expanded material 3, plastic stent 2 is connected with expanded material 3, and an end of plastic stent 2 is provided with a buckle 1 at least, and by buckle 1 plastic stent 2 and expanded material 3 is fixed on the auto body sheet metal component.
The automobile sound arrester can be designed as two dimension or three-dimensional structure in conjunction with shape, the size flexible design of bodywork cavity.Buckle 1 is one or more, is positioned at an end of plastic stent, and buckle 1 and plastic stent 2 can be processed as one, by buckle the automobile sound arrester is fixed on the bodywork cavity sheet metal component, thus the problem of having avoided original quieter material to be difficult to fix.
Expanded material 3 in the automobile sound arrester is the high temperature expandable materials based on plastic basis material (as EVA), and expanded material 3 links to each other with plastic stent 2 by the mode that embeds.Another kind of connection mode is that expanded material 3 links to each other with plastic stent 2 by injection molding way.
When the automobile sound arrester was installed on the automobile, fixed by snap on the sheet metal component of bodywork cavity, insertion force is pine or too tight too.Enter electrophoresis operation high-temperature baking with auto body then, promptly expanded foamed after expanded material is heated, fully fill bodywork cavity, thereby reach the purpose that intercepts air and reduce noise.
