Description
본 발명은 자동차의 소음 차단구조에 관한 것이다.The present invention relates to a noise blocking structure of an automobile.
일반적으로 자동차를 주행함에 있어서는 쾌적한 실내 환경을 유지하기 위하여 정숙성을 요망하고 있다.In general, in driving a car, quietness is required to maintain a comfortable indoor environment.
이와같은 정숙성을 좌,우하는 요소로써는, 차 외부에서 발생되는 소음이 내부로 유입되는 것을 차단하는 것과, 차 내부에서 발생되는 잔향 소음을 효과적으로흡음하는 것이다.Such quiet and quiet factors include preventing noise generated from the outside of the vehicle from entering the interior and effectively absorbing reverberation noise generated from the interior of the vehicle.
이와같이 소음 차단을 위하여 도 1에서와 같이 바디 패널(body panel;10)과 차 내부의 트림(trim;20) 사이에 공간부(H)를 형성하고, 이 공간부(H)상에 펠트(felt)류의 차음재(30)를 개재하여, 실외의 소음이 내부로 유입되는 것을 차단하고 있다.As described above, the space H is formed between the body panel 10 and the trim 20 of the vehicle, and the felt is felt on the space H to block the noise. Through the sound insulation material 30 of), the outside noise is prevented from entering inside.
그러나 이와같은 종래 구조에 있어서는, 단지 차음재(30)가 실외에서 발생되는 소음이 실내로 유입되는 것을 차단하는 기능만을 수행할 뿐이어서, 근래에 미세하지만 차 내부에서 발생되는 잔향 소음에 대처하지 못함으로써 정숙성을 떨어뜨리는 문제점이 내재되어 있다.However, in such a conventional structure, the sound insulating material 30 only performs a function of blocking the noise generated in the outdoors from entering the room, thereby failing to cope with the reverberation noise generated in the recent but fine car interior. There is a problem that impairs quietness.
즉, 실내에서 발생되는 잔향 소음을 흡음하기 위한 어떠한 수단도 마련되어 있지 않음으로써 이 소음이 트림(20)을 통해 반사되어 실내 소음도를 악화시키고 있다.That is, since no means for absorbing the reverberation noise generated in the room is provided, the noise is reflected through the trim 20 to worsen the room noise level.
본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 실외의 소음 차단이 안정되게 이루어질 뿐만 아니라 실내에서 발생되는 잔향 소음을 효과적으로 흡음함으로써 정숙한 실내 환경을 유지할 수 있는 자동차의 소음 차단구조를 제공함에 그 목적이 있다.The present invention was created in order to solve such a conventional problem, and the noise blocking structure of the vehicle that can maintain a quiet indoor environment by effectively absorbing the reverberation noise generated in the room as well as the noise blocking in the outside is made stable. The purpose is to provide.
상기한 목적을 달성하기 위하여 본 발명은, 바디 패널과 내부 트림 사이의 공간부상에 차음재를 개재하고, 차음재와 대응되는 트림의 외측면에는 소정깊이로 홈부를 마련하여 흡음재를 개재하며, 상기 흡음재의 노출면을 마감재로 마감처리하여 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention, through the sound insulating material on the space portion between the body panel and the inner trim, and to the outer surface of the trim corresponding to the sound insulating material to provide a groove portion to a predetermined depth through the sound absorbing material, It is characterized by that the exposed surface is finished with a finish.

도 1 및 도 2에서와 같이 본 발명은, 바디 패널(body panel;10)과 트림(trim;20)사이에는 공간부(H)가 마련되며, 이 공간부(H)로는 외부 소음을 차단하기 위한 차음재(1)가 개재된다.As shown in FIGS. 1 and 2, the space H is provided between the body panel 10 and the trim 20 to block external noise. Sound insulating material (1) for intervening.
이러한 차음재(1)로는 폴리우레탄 폼(PU Foam)이 사용된다.As the sound insulating material 1, polyurethane foam (PU Foam) is used.
그리고 이 차음재(1)가 설치된 부위와 대응되는 차 내부의 트림(20)상에는 차음재(1)를 향하여 소정깊이로 홈부(21)가 형성된다.The groove 21 is formed at a predetermined depth toward the sound insulation material 1 on the trim 20 inside the vehicle corresponding to the portion where the sound insulation material 1 is installed.
이와같이 트림(20)상에 홈부(21)를 형성함에 의해 차음재(1)는 샌드위치 형상으로 바디 패널(10)과 트림(20)사이에 개재되어진다.By forming the groove 21 on the trim 20 in this way, the sound insulating material 1 is sandwiched between the body panel 10 and the trim 20 in a sandwich shape.
이러한 샌드위치 형상은 가장 이상적인 소음 차단의 효과를 갖는 것이다.This sandwich shape has the most ideal noise blocking effect.
한편, 전술한 트림(20)의 홈부(21)에는 실내에서 발생되는 잔향 소음을 흡음하기 위한 흡음재(2)가 개재된다.Meanwhile, the sound absorbing material 2 for absorbing reverberation noise generated in the room is interposed in the groove 21 of the trim 20 described above.
이러한 흡음재(2)로는 소음 흡수가 우수한 펠트(felt)가 사용되거나 또는 스폰지체등이 사용된다.As the sound absorbing material 2, a felt having excellent noise absorption is used, or a sponge or the like is used.
또한 흡음재(2)가 개재되는 트림(20)의 홈부(21) 표면에는 흡음재(2)가 노출되지 않도록 마감재(3)가 설치되는 바, 특히 이 마감재(3)의 표면에는 다수의 관통구멍(3a)이 형성된다.In addition, the finishing material 3 is provided on the surface of the groove portion 21 of the trim 20 in which the sound absorbing material 2 is interposed so that the sound absorbing material 2 is not exposed. In particular, the surface of the finishing material 3 has a plurality of through holes ( 3a) is formed.
이와같이 마감재(3)에 관통구멍(3a)을 형성하는 것은, 어느 특정한 직경의 관통구멍(3a)을 형성할 경우 차 내부에서 가장 심하게 발생되는 영역의 소음 주파수를 흡음할 수 있는 효과를 발휘하기 때문이다.Forming the through hole 3a in the finishing material 3 as described above is effective in absorbing the noise frequency of the most severely generated area inside the car when forming the through hole 3a having a specific diameter. to be.
이와같이 구성된 본 발명은, 자동차가 주행하는 과정에서 차 외부에서 발생되는 실외소음은, 바디 패널(10)과 트림(20) 사이에 개재된 폴리우레탄 폼으로 형성된 차음재(1)에 의해 차단되며, 실내에서 발생되는 잔향 소음은, 차음재(1)와 대응되는 트림(20)의 홈부(21)에 개재된 펠트류의 흡음재(2)를 통해 흡수할 수 있게된다 .According to the present invention configured as described above, the outdoor noise generated outside the vehicle in the course of driving the vehicle is blocked by the sound insulating material 1 formed of polyurethane foam interposed between the body panel 10 and the trim 20, and indoors. The reverberation noise generated by the sound absorbing material can be absorbed through the sound absorbing material 2 of the felt interposed in the groove portion 21 of the trim 20 corresponding to the sound insulating material 1.
이때 특히 홈부(21)를 차단하고 있는 마감재(3)의 표면에는 일정 주파수 대역의 잔향 소음을 효과적으로 흡음할 수 있도록 관통구멍(3a)이 형성되어 있기 때문에 보다 효과적인 흡음 효과를 얻을 수 있게된다In this case, the through hole 3a is formed on the surface of the finishing material 3 blocking the groove 21 so as to effectively absorb reverberation noise of a predetermined frequency band, thereby obtaining a more effective sound absorbing effect.
이상과 같이 본 발명은, 자동차를 주행하는 과정에서 실외 및 실내에서 발생되는 소음을 차음재로 차단할 수 있고 흡음재로 흡음할수 있게되어 정숙한 실내 환경을 유지할 수 있는 이점이 있다.As described above, the present invention has the advantage of being able to block the noise generated in the outdoors and indoors in the process of driving a vehicle with sound insulation material and to absorb sound absorbing material to maintain a quiet indoor environment.
또한 실내 잔향 소음을 흡수할 때 마감재상의 관통구멍을 통해 보다 효과적인 흡음의 효과를 얻을 수 있게되어 더욱 정숙한 실내 환경을 유지할 수 있게된다.In addition, when absorbing room reverberation noise, a more effective sound absorption effect can be obtained through the through hole on the finishing material, thereby maintaining a quieter indoor environment.
