Description
本新型係有關一種吸音抗震結構，尤指一種供選擇以應用於一汽車鈑金之車門部位、引擎部位、輪弧部位、底盤部位及後車廂部位等部位鈑金中任一部位鈑金上之吸音抗震結構，藉以提昇該汽車鈑金之吸音抗震效果。The present invention relates to a sound absorbing and anti-vibration structure, and more particularly to a sound absorbing and anti-vibration structure which is selected for use in a sheet metal part, an engine part, an arc part, a chassis part and a rear part of a car sheet metal. In order to enhance the sound absorption and shock resistance of the automobile sheet metal.
大部分汽車之外殼係由金屬材質製成，一般通稱為汽車鈑金，該汽車鈑金大致上可分為車門部位、引擎部位、輪弧部位、底盤部位及後車廂部位等多個部位鈑金，各部位鈑金與各部位所配合安裝之各種零配件在行駛中容易因震動而發出聲響，且震動聲響所形成之噪音很容易滲透至汽車內部而導致駕駛人或乘客的困擾，例如當車主特別安裝高級汽車音響而欲在開車過程中享受時，該等震動噪音卻會直接影響到高級汽車音響所播放音樂的品質，使安裝高級汽車音響等於白費功夫。Most of the car's outer casing is made of metal material, generally known as automobile sheet metal. The car sheet metal can be roughly divided into door parts, engine parts, wheel parts, chassis parts and rear parts. Sheet metal and various parts installed in various parts are easy to make sounds due to vibration during driving, and the noise generated by the vibration sound easily penetrates into the interior of the car and causes trouble to the driver or passenger, for example, when the owner installs a special car. When the sound is intended to be enjoyed during the driving process, the vibration noise will directly affect the quality of the music played by the advanced car audio, making it difficult to install the advanced car audio.
在習知汽車領域中，雖已存在一些供可安裝在汽車上使用以產生吸音抗震功能的先前技術，如TW181558及TW359231所揭示。然而，該些先前技術大都是利用玻璃纖維（Fiber-reinforced plastic，FRP）或聚氨酯（Polyurethane，PU）等習知材料來製成或用以形成吸音抗震結構，上述習知材料在重量、吸音效率、安裝作業、壓縮及成型性、或不吸水性等特性或功效方面皆遠遠不如美國3M公司利用吹熔微纖維無紡布技術(Blow micro fiber technology) 所製作的吸音棉系列產品。此外，玻璃纖維及聚氨酯雖可提供抗震功效，但各別的抗震效果亦遠遠不如專用於抗震的制震墊如美國3M公司所製作的高性能阻尼制震墊系列產品，因此習知的吸音抗震技術尚無法使汽車內部能有效地避免受到汽車鈑金震動噪音之困擾。此外，習知的吸音抗震技術並未專門針對汽車鈑金中較容易產生噪音之各部位鈑金去做出有效率的吸音抗震結構，例如各部汽車中容易在行駛中因震動而產生噪音之部位鈑金可能有所不同，因此當某一部位鈑金因行駛震動而產生噪音時，此時才要針對該一部位鈑金去安裝特定的吸音抗震結構，如此的作法不但費時費工又相對增加吸音抗震結構的安裝成本，而且臨時急就章的安裝方法，所產生的吸音抗震效果必然相對不彰，也無法滿足消費者（如車主）急欲解決汽車內部有噪音產生的問題。因此，習知汽車鈑金所使用的吸音抗震結構確實有改良的需要。In the field of conventional automobiles, there have been some prior art techniques that can be installed on automobiles to produce sound absorbing and anti-vibration functions, as disclosed in TW181558 and TW359231. However, most of the prior art techniques are made of conventional materials such as Fiber-reinforced plastic (FRP) or Polyurethane (PU), or are used to form a sound absorbing and anti-vibration structure. The characteristics or efficacy of installation work, compression and formability, or non-absorbability are far less than those of 3M's sound-absorbing cotton series made by Blow micro fiber technology. In addition, although glass fiber and polyurethane can provide anti-shock effect, the individual seismic effects are far less than those of shock-absorbing cushions specially designed for earthquake resistance, such as the high-performance damping shock pad series produced by 3M Company of the United States. The anti-seismic technology has not been able to effectively prevent the interior of the car from being plagued by the vibration of the automobile sheet metal. In addition, the conventional sound-absorbing and anti-vibration technology does not specifically aim at the parts of the automobile sheet metal that are more prone to noise, and to make an effective sound-absorbing and anti-vibration structure. For example, the parts of the automobile that are easy to generate noise due to vibration during driving may be gold. It is different, so when a part of the sheet metal is noisy due to running vibration, it is necessary to install a specific sound-absorbing and anti-vibration structure for the sheet metal at this time. This method not only takes time and labor, but also relatively increases the installation of the sound-absorbing and anti-vibration structure. The cost, and the temporary installation method of the chapter, the resulting sound-absorbing and anti-seismic effect is inevitably relatively inconsistible, and it is unable to satisfy the problem that consumers (such as car owners) are anxious to solve the problem of noise inside the car. Therefore, the sound-absorbing and anti-vibration structure used in the conventional automobile sheet metal does have an improvement need.
