Description
본 발명은 자동차 제진구조에 관한 것으로서, 더욱 상세하게는 차체 플로어(Floor)부를 이루고 있는 제진재 중의 아스팔트 패드부를 아스팔트 패드, 펠트 또는 부직포, 그리고 아스팔트 패드층으로 이루어지도록 함으로써 제진성능이 우수하고 차음 및 흡음성능이 향상된 자동차의 제진구조에 관한 것이다.The present invention relates to an automobile vibration damping structure, and more particularly, to make the asphalt pad part of the vibration damping material forming the vehicle floor part composed of an asphalt pad, a felt or nonwoven fabric, and an asphalt pad layer. The present invention relates to a vibration suppression structure of an automobile having improved sound absorption performance.
일반적으로 차체 플로어부는 안쪽으로부터 수지구속층, 아스팔트 패드 및 플로어 판넬로 이루어지는데, 아스팔트 패드는 제진성능을 위한 층이다. 그러나, 아스팔트 패드는 그 제진성능은 우수하나 전체 주파수 영역을 조절하지는 못하며, 차음 및 흡음 효과는 미미하다.Generally, the vehicle body floor portion is composed of a resin binding layer, an asphalt pad, and a floor panel from the inside, and the asphalt pad is a layer for vibration damping performance. However, the asphalt pad has excellent vibration damping performance but does not control the entire frequency range, and the sound insulation and sound absorption are insignificant.
따라서, 본 발명자는 종래 차체 플로어 구조의 제진성능과 차음흡음 효과를 증진시키기 위해 노력한 결과, 아스팔트 패드부로만 이루어진 종래의 제진패드를 아스팔트 패드, 펠트 또는 부직포 및 아스팔트 패드로 이루어지도록 함으로써 본 발명을 완성하였다.Therefore, the inventors of the present invention confirmed the vibration suppression performance and sound insulation of a conventional vehicle body floor structure. As a result of efforts to enhance the sound absorbing effect, the present invention has been completed by making a conventional vibration damping pad consisting of only an asphalt pad portion consisting of an asphalt pad, a felt or a nonwoven fabric, and an asphalt pad.
본 발명은 제진성능이 우수하고 차음흡음 성능이 향상된 제진구조를 제공하는데 그 목적이 있다.The present invention has excellent vibration damping performance and sound insulation The purpose is to provide a vibration damping structure with improved sound absorption performance.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 플로어 판넬, 제진패드층 및 수지구속층으로 이루어진 자동차 제진구조에 있어서, 상기 제진패드층은 수지구속층으로부터 아스팔트 패드 1.51.6 mm, 펠트 또는 부직포 0.40.5mm 및 아스팔트 패드 1.51.6 mm 두께로 적층되어 이루어진 것을 그 특징으로 한다.The present invention is a vehicle vibration damping structure consisting of a floor panel, a damping pad layer and a resin binding layer, wherein the damping pad layer is asphalt pad 1.5 from the resin binding layer. 1.6 mm, felt or nonwoven 0.4 0.5mm and asphalt pad 1.5 It is characterized by being laminated to a thickness of 1.6 mm.
이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명은 제진패드층을 달리하여 차음흡음 성능이 우수한 제진구조에 관한 것으로서, 본 발명의 제진패드층은 종래의 제진패드층이 아스팔트 패드층으로만 이루어진 것에 비해 펠트 또는 부직포층을 내장한다.The present invention is sound insulation by different vibration damping pad layer The present invention relates to a vibration damping structure having excellent sound absorption performance, and the vibration damping pad layer of the present invention incorporates a felt or nonwoven layer as compared with a conventional vibration damping pad layer made of only an asphalt pad layer.
제진패드층은 아스팔트 패드 1.51.6mm, 펠트 또는 부직포 0.40.5 mm 및 아스팔트 패드 1.51.6 mm로 종래 층두께의 범위내에서 펠트 또는 부직포층을 넣음으로써 흡음율을 향상시킬 수 있다.The damping pad layer is asphalt pad 1.5 1.6mm, felt or nonwoven 0.4 0.5 mm and asphalt pads 1.5 The sound absorption rate can be improved by adding a felt or nonwoven fabric layer within the range of the conventional layer thickness of 1.6 mm.
이때 펠트 또는 부직포층의 두께가 상기 범위를 벗어나면 흡음성이 떨어지는 문제가 있다.At this time, if the thickness of the felt or nonwoven layer is out of the range there is a problem that the sound absorption is inferior.
이 제진패드층을 이용하여 차체 플로어부를 성형하는 방법은 종래와 유사하다.The method of shaping the vehicle body floor portion using this damping pad layer is similar to the conventional one.
이와 같이 제조된 본 발명의 제진구조는 부직포나 펠트를 첨가하여 이루어진 제진패드를 갖음으로써 제진성능 뿐만 아니라 흠음차음 성능이 우수하다.The vibration damping structure of the present invention manufactured as described above has a vibration damping pad made by adding a nonwoven fabric or felt, thereby preventing not only vibration damping performance but also flaw. Excellent sound insulation performance.
