Description

차량의 쿼드런트 내측커버 방음구조{Soundproof structure of quadrant inner cover in vehicle}Soundproof structure of quadrant inner cover in vehicle}

본 발명은 차량의 쿼드런트 내측커버 방음구조에 관한 것으로, 특히 흡음패드와 공명실을 구비하고서 차량의 주행소음을 효과적으로 저감하도록 한 차량의 쿼드런트 내측커버 방음구조에 관한 것이다.The present invention relates to a quadrant inner cover soundproof structure of a vehicle, and more particularly, to a quadrant inner cover soundproof structure of a vehicle provided with a sound absorbing pad and a resonance chamber to effectively reduce running noise of the vehicle.

종래 차량의 아웃사이드 미러는 도 1에 도시한 바와 같이, 도어에 형성된 미러장착패널(1)에 차량의 외측에서 아웃사이드 미러(2)가 덧대어지고, 상기 미러장착패널(1)의 내측에서는 쿼드런트 내측커버(3)가 상기 아웃사이드 미러와 결합되어 아웃사이드 미러의 결합강성을 유지하게 된다.In the conventional exterior mirror of the vehicle, as shown in FIG. 1, the exterior mirror 2 is padded on the outside of the vehicle to the mirror mounting panel 1 formed on the door, and inside the mirror mounting panel 1. The quadrant inner cover 3 is combined with the outside mirror to maintain the bonding rigidity of the outside mirror.

상기 쿼드런트 내측커버(3)는 대체로 삼각형상을 이루고서 내측면에 외측을 향해 다수개의 보스(3a)가 돌출되어 형성되고, 상기 아웃사이드 미러(2)의 장착부(2a)는 상기 미러장착패널(1)에 3개의 볼트로 체결되어 지지되며, 상기 장착부(2a)에는 전원을 공급하기 위한 와이어링 커넥터(2b)가 구비되어 있다.The quadrant inner cover 3 has a substantially triangular shape and is formed by protruding a plurality of bosses 3a outward on an inner surface thereof, and the mounting portion 2a of the outside mirror 2 is formed by the mirror mounting panel ( It is fastened and supported by three bolts in 1), and the mounting portion 2a is provided with a wiring connector 2b for supplying power.

상기와 같이 아웃사이드 미러가 장착된 상태에서 차량이 주행할 경우에 아웃사이드 미러가 볼트로 체결되는 볼트 장착부의 조립홀과 와이어링 커넥터의 주위에 서 고주파 주행 소음이 발생하여 승차감을 저하시키게 된다.As described above, when the vehicle travels in a state where the outside mirror is mounted, high-frequency driving noise is generated around the assembly hole and the wiring connector in which the outside mirror is fastened by the bolt, thereby lowering the riding comfort.

상기와 같은 주행 소음을 저감하기 위해 종래에는 도 2에는 도시한 바와 같이 흡음 패드(4)를 쿼드런트 내측패널에 끼우는 형태로 조립하고 있었다.In order to reduce the running noise as described above, as shown in FIG. 2, the sound absorbing pad 4 is assembled into a quadrant inner panel.

그런데 상기와 같이 흡음 패드(4)를 적용하는 경우에 패드의 두께를 30mm 내지 40mm까지 높여서 틈새를 막더라도 아웃사이드 미러 주변의 복잡한 공기흐름으로 인한 와류 때문에 미세한 틈새나 위약한 실링부를 통해 소음이 실내로 유입되는 문제점이 있었다.However, in the case of applying the sound absorbing pad 4 as described above, even if the thickness of the pad is increased to 30 mm to 40 mm, even though the gap is prevented, the noise is indoors through the minute gap or the weak sealing part due to the vortex caused by the complicated air flow around the outside mirror. There was a problem flowing into.

또한 흡음 패드를 장착하거나 쿼드런트 내측커버를 장착할 때에 장착 산포로 인해 미세한 틈새가 발생하고, 이러한 틈새를 통해 고주파 주행 소음이 실내로 유입되어 승차감을 저하시키는 결점이 있었다.In addition, when the sound absorbing pad is mounted or the quadrant inner cover is mounted, a small gap is generated due to the scattering of the mounting pad, and high frequency driving noise is introduced into the room through such a gap, thereby degrading the riding comfort.

상기와 같은 결점을 해소하기 위해 아웃사이드 미러의 베이스에 발포 패드를 다량으로 붙이고, 실링 립을 형성하여 미러장착패널과의 실링성을 향상시키는 노력이 있었지만, 실링 불량으로 인한 고주파 주행 소음의 실내 유입을 만족스럽게 차단하지 못하고 있었다.Efforts have been made to improve the sealing performance with the mirror mounting panel by attaching a large amount of foam pads to the base of the outside mirror and forming a sealing lip in order to solve the above drawbacks. Could not block satisfactorily.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 아웃사이드 미러를 통해 차실내로 유입되는 고주파 주행소음을 흡음패드를 매개로 1차적으로 감소하여 저감시킴과 더불어 상기 흡음 패드에서 미처 흡수되지 못한 소음은 공명실을 통해 2차적으로 저감되게 해서 차량의 주행소음의 실내유입을 효과적으로 저감시켜 차량 의 승차감을 개선할 수 있도록 한 차량의 쿼드런트 내측커버 방음구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described circumstances, and primarily reduces and reduces the high-frequency driving noise introduced into the cabin through the outside mirror through the sound absorbing pad, and is not absorbed by the sound absorbing pad. The purpose of the present invention is to provide a soundproof structure for the quadrant inner cover of the vehicle to reduce noise in the room through the resonance room to effectively reduce the inflow of running noise of the vehicle to improve the ride comfort of the vehicle.

상기와 같은 목적을 달성하기 위한 본 발명은, 아웃사이드 미러와 결합되는 쿼드런트 내측커버의 내측면에 상기 쿼드런트 내측커버의 볼트 장착홀과 와이어링 커넥터 연결부 주위를 포위하는 형태로 보스가 일체로 돌출해서 형성되고, 상기 보스의 개구부를 덮어서 밀폐시키도록 흡음패드가 부착되어 있다.The present invention for achieving the above object, the boss is integrally protruded in the form of surrounding the bolt mounting hole and the wiring connector connecting portion of the quadrant inner cover on the inner surface of the quadrant inner cover coupled to the outside mirror And a sound absorbing pad is attached to cover and seal the opening of the boss.

본 발명에 따른 차량의 쿼드런트 내측커버 방음구조에 의하면, 쿼드런트 내측커버의 내측면에 흡음패드로 밀폐되는 공명실이 형성되어, 아웃사이드 미러의 주변에서 발생하는 주행소음이 미러장착패널을 통해 쿼드런트 내측커버로 유입될 때에 상기 흡음 패드가 주행소음을 1차적으로 흡수해서 저감시키고, 상기 흡음패드에서 미처 흡수되지 못한 주행소음은 흡음패드를 통해 상기 공명실로 유입되어 2차적으로 저감됨으로써, 차량의 주행중에 아웃사이드 주변에서 발생하여 차실내부로 유입되는 주행소음을 효과적으로 차단해서 차량의 승차감을 향상시키는 등의 효과가 있다. According to the soundproof structure of the quadrant inner cover of the vehicle according to the present invention, a resonance chamber sealed by a sound absorbing pad is formed on the inner surface of the quadrant inner cover, so that the running noise generated around the outside mirror is inside the quadrant through the mirror mounting panel. When the sound absorbing pad is introduced into the cover, the sound absorbing pad is primarily absorbed and reduced, and the running noise which is not absorbed by the sound absorbing pad is introduced into the resonance chamber through the sound absorbing pad and is reduced secondly, thereby driving the vehicle. Effectively blocking driving noise generated in the outside and flowing into the interior of the vehicle, it is effective to improve the ride comfort of the vehicle.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 3에는 본 발명에 따라 공명실과 흡음패드가 부착된 쿼드런트 내측커버의 사시도가 도시되어 있고, 도 4에는 도 3의 A-A선 단면이 도시되어 있는 바, 즉 대 체로 삼각형상을 이루는 쿼드런트 내측커버(11)의 내측면에는 대체로 삼각형상을 이루는 보스(12)가 일체로 돌출해서 형성되고, 상기 보스(12)의 외주면에는 보스의 강성을 강화시키는 다수개의 리브(12a)가 일정한 간격을 두고 돌출해서 형성된다.FIG. 3 is a perspective view of a quadrant inner cover to which a resonance chamber and a sound absorbing pad are attached according to the present invention, and FIG. 4 is a cross-sectional view of the AA line of FIG. 3, that is, a quadrant inner cover having a substantially triangular shape ( The inner surface of 11) bosses 12, which are generally triangular in shape, are integrally formed, and on the outer circumferential surface of the boss 12, a plurality of ribs 12a for reinforcing the rigidity of the bosses are projected at regular intervals. Is formed.

상기 보스(12)의 개구부에는 흡음 패드(13)가 밀폐하는 형태로 부착되어, 상기 보스와 흡음 패드에 의해 소정 크기의 공명실(14)이 쿼드런트 내측커버에 형성되게 된다.The sound absorbing pad 13 is attached to the opening of the boss 12 in a sealed manner, and the resonance chamber 14 having a predetermined size is formed in the quadrant inner cover by the boss and the sound absorbing pad.

상기와 같이 삼각형상의 보스가 아웃사이드 미러의 주변에서 발생하여 차실내부로 유입되는 부위인 볼트(15) 장착홀 주변과 와이어링 커넥터 주위를 감싸는 형태로 형성됨에 따라 상기 소음 유입부를 통해 유입되는 소음은 1차적으로 상기 흡음 패드에 의해 흡수되어 저감되고, 상기 흡음 패드에 의해 미처 흡수되지 못한 소음은 상기 보스와 흡음 패드에 의해 형성된 공명실에서 2차적으로 감쇄되어 저감되므로, 차실내부로 유입되는 주행소음을 확실하게 차단해서 차량의 승차감을 향상시키게 된다.As described above, the triangular boss is formed around the mounting hole of the bolt 15, which is a portion of the outside mirror, which flows into the interior of the vehicle interior, and surrounds the wiring connector. The noise that is primarily absorbed and reduced by the sound absorbing pad and is not absorbed by the sound absorbing pad is attenuated and reduced secondarily in the resonance chamber formed by the boss and the sound absorbing pad. It is possible to reliably shut off the vehicle to improve the ride comfort.

그리고 상기 보스의 높이를 적절히 설정하면 흡음 패드의 필요 두께를 최소한으로 줄여서 원가 절감을 도모할 수 있고, 상기 보스와 이에 형성된 리브로 쿼드런트 내측커버의 강성을 증대시킬 수 있는 부가적인 효과도 있다.In addition, if the height of the boss is appropriately set, the required thickness of the sound absorbing pad can be reduced to the minimum, and the cost can be reduced, and the rigidity of the boss and the rib quadrant inner cover formed thereon has an additional effect.
