Abstract
The utility model provides a silencing board for an automobile engine, which comprises a bottom board, wherein a plurality of hollow cavity bodies which are enclosed by cavity body boards are arranged on the bottom board in a parallel way; at least a plurality of through holes are arranged in the top surface of the cavity bodies; silencing materials are arranged in the cavity bodies; the cavity body boards and the bottom board are in a split structure; connecting plates are arranged among the cavity body boards; the connecting boards are arranged on the bottom board through a fixing device; the cross section of each hollow cavity body forms a tetragonal shape; the through holes form circular shapes, square shapes or other irregular shapes. The silencing board for an automobile engine has the advantages of good silencing effect, low cost, sand, dust and fire prevention effects so as to provide high quality environmental protection materials for the reduction of automobile noises.
Description
Technical field
The utility model relates to a kind of acoustical panel, is specifically related to a kind of automotive engine acoustical panel.
Background technology
Along with the progress of society and the raising of people's living standard, the quantity of automobile is more and more, purposes more and more widely, automobile has become the indispensable vehicle in people's daily life.
Automobile is when facilitating for life, also brought negative influence to people's life, as noise pollution, car noise is mainly derived from driving engine, for reducing the noise that driving engine produces, usually at automotive engine outer wrapping quieter material, original quieter material is generally acoustical panel, acoustical panel is directly processed by quieter material, because the restriction of the character of quieter material own, quieter material erasure effect is undesirable.Along with the raising of society to environmental protection requirement; less car noise pollutes becomes an investigation of automotive performance requirement index; therefore auto trade demands requiring a kind of good muffling effect of invention urgently, and cost is low, and have concurrently noise reduction, sand prevention, dustproof, fire prevention more can the automotive engine acoustical panel.
Summary of the invention
The utility model has overcome the shortcoming that existing automotive engine acoustical panel exists, and provides a kind of acoustical panel of structural development, this acoustical panel good muffling effect, cost is low, and have sand prevention, dustproof, fire-proof function concurrently, for reducing car noise, provide the special quality environment-friendly materials.
For realizing goal of the invention of the present utility model, the utility model has adopted following technical proposals.
The utility model discloses a kind of automotive engine acoustical panel, it is characterized in that,
This acoustical panel comprises base plate, is arranged with a plurality of hollow cavities that surrounded by the cavity plate on the described base plate in parallel, and the end face of described at least cavity is provided with a plurality of open-works, is provided with quieter material in the described cavity.
In the technique scheme, the automotive engine acoustical panel comprises base plate, base plate is a sealing plate material, but actv. plays sand prevention, antisoiling effect, is provided with the cavity that the cavity plate surrounds by base plate, in cavity, fill quieter material, can effectively reduce the noise of car engine, and open-work is set on the cavity plate, the noise of driving engine is further absorbed, the noise of driving engine further reduces.Be provided with the cavity of a plurality of hollows, can make things convenient for the filling of quieter material, and strengthen the erasure effect of acoustical panel.
Automotive engine acoustical panel base plate and cavity plate can adopt common plastic working to form, and the quieter material that is filled in the cavity can adopt quieter materials such as ADS engineering plastics.
The base plate of automotive engine acoustical panel, cavity plate and quieter material select fire-proofing material to process usually, and to prevent presence of fire accident under specific circumstances, fire-proofing material also can further prevent propagation of flame when presence of fire.
Be processing and the assembling that makes things convenient for acoustical panel, described cavity plate and described base plate are provided with connecting plate for dividing body structure between the described cavity plate, and described connecting plate is fixed on the base plate by anchor fitting.
The cavity that the cavity plate surrounds can be various cross section structures, as long as can be convenient to the filling of quieter material, for ease of the filling of quieter material, the cross section of described hollow cavity is cubic type.
Open-work can be acoustical panel good erasure effect is provided, and described open-work is circular, square or other is irregularly shaped.
Above-mentioned automotive engine acoustical panel can be automotive engine good silencing function is provided, and cost is low, and has sand prevention, dustproof, fire-proof function concurrently, provides a kind of environment-friendly function good quieter material.

Fig. 2 be among Fig. 1 A-A to the structure cutaway view Amplified image.
The specific embodiment
Automotive engine acoustical panel as shown in Figure 1,
This automotive engine acoustical panel comprises base plate 1, is arranged with a plurality of hollow cavities 3 that surrounded by cavity plate 2 on the base plate 1 in parallel, and cavity includes end face 31 and side 32 and bottom surface 33, and the end face of cavity is provided with a plurality of open-works 4, is provided with quieter material 5 in the cavity 4.
Anchor fitting includes two rivets, and rivet 7 passes base plate and connecting plate, and rivet 8 is riveted with the part that rivet 7 passes base plate and connecting plate top, and base plate and connecting plate are fixed.
As shown in Figure 2, the cross section of hollow cavity is cubic type.
Open-work is circular as shown in Figure 1.
In the above-mentioned specific embodiment, automotive engine acoustical panel base plate and cavity plate can adopt common plastic working to form, and the quieter material that is filled in the cavity can adopt plastics quieter materials such as (plastic).
The base plate of automotive engine acoustical panel, cavity plate and quieter material select fire-proofing material to process usually, and to prevent presence of fire accident under specific circumstances, fire-proofing material also can further prevent propagation of flame when presence of fire.
Open-work can adopt circle, square or other is irregularly shaped.
The above-mentioned specific embodiment is not the qualification to the utility model protection domain, and according to inventive concept of the present utility model, the specific embodiment can be done various variations.
