본 고안은 자동차의 공명기에 관한 것으로, 보다 자세하게는 자동차의 배기장치 후단에 형성되어 있는 테일파이프의 공명기를 설치하여 배기장치로 배출되는 소음을 줄이기 위한 자동차의 공명기에 관한 것이다.The present invention relates to a resonator of a vehicle, and more particularly, to a resonator of a vehicle for reducing the noise emitted to the exhaust system by installing a resonator of the tail pipe formed in the rear end of the vehicle.

자동차의 배기장치는 각 실린더로부터 배출되는 연소가스를 모으는 배기다기관과, 배기가스를 차량 후방으로 빼내는 배기파이프와 배기가스중의 유해성분을 정화하는 촉매컨버터 그리고, 배기시 소음을 절감시키는 소음기와, 테일파이프로 구성되며, 기관에서 배기밸브가 열려 배기가스가 실린더 밖으로 배출될 때는 고온, 고압의 배기가스와 고주파음향이 발생하며,이로 인해 매우 큰 소음이 발생하므로 승차감이 떨어지게 된다.The exhaust system of a vehicle includes an exhaust manifold that collects combustion gas discharged from each cylinder, an exhaust pipe for exhausting exhaust gas to the rear of the vehicle, a catalytic converter for purifying harmful components in the exhaust gas, a silencer for reducing noise during exhaustion, It is composed of tail pipe, and exhaust valve is opened in the engine and exhaust gas is discharged out of cylinder, and high-temperature and high-pressure exhaust gas and high frequency sound are generated.

그래서, 소음을 줄이고 승차감을 향상시킬 목적으로 관벽에 여러개의 작은 구멍을 천공하고, 그 바깥으로 동심관의 공명상자를 만들어 그 속에 내열성의 흡음재를 삽입한 소음기를 사용하였다.Therefore, in order to reduce noise and improve ride comfort, a small hole was drilled in the wall of the pipe, a resonance box of the concentric pipe was made outside, and a silencer in which heat-resistant sound absorbing material was inserted therein was used.

소음을 줄여 승차감을 더욱 더 향상시킬 목적으로, 첨부도면 제1도에 도시한 바와 같이 테일파이프(50) 후단에 테일파이프(50) 내경과 동일한 크기의 외경에 다수개의 구멍(53)을 천공한 공명기(52)를 설치하였으나, 음향의 에너지를 낮은 저항으로 소모시키기 위해서는 충돌을 많이 일으킬 수 있는 되도록 넓은 단면적을 필요로 하는데, 상기와 같은 형상은 충돌을 일으킬 수 있는 단면적이 적어 부적합한 형상을 하고 있다.In order to further improve the riding comfort by reducing the noise, as shown in FIG. 1 of the accompanying drawings, a plurality of holes 53 are drilled in the outer diameter of the same size as the inner diameter of the tail pipe 50 at the rear end of the tail pipe 50. Although the resonator 52 is installed, in order to consume the energy of the sound with a low resistance, a large cross-sectional area is required to cause a lot of collision. The above-described shape has an inadequate shape due to a small cross-sectional area that can cause a collision. .

본 고안은 상기한 바와 같은 제반 문제점들을 해소하고자 안출한 것으로, 자동차의 배기가스 소음을 줄이고, 이에 따라 승차감을 향상시키려는데 그 목적이 있는 것이다.The present invention has been made to solve the problems described above, the purpose is to reduce the exhaust gas noise of the vehicle, thereby improving the ride comfort.

이러한 본 고안의 목적을 달성하기 위하여 배기가스 입구측과 배출구측을 길이 방향으로 구획하도록 다수개의 구멍을 천공한 충돌판에 서로 엇갈리는 방향으로 완곡부를 두고 복수개의 차단판을 충돌판의 양끝단에 형성하여 테일파이프 내부에 융착시켜 자동차의 공명기가 제공된다.In order to achieve the object of the present invention, a plurality of blocking plates are formed at both ends of the collision plate with a bent portion in the direction opposite to each other in a collision plate perforated with a plurality of holes to partition the exhaust gas inlet side and the outlet side in the longitudinal direction. It is then fused inside the tailpipe to provide a resonator for the vehicle.

이하 본 고안에 따른 자동차의 공명기를 첨부도면을 참조하여 다음과 같이 상세히 설명한다.Hereinafter, a resonator of a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 제2도는 본 고안에 따른 자동차의 테일파이프의 공명기를 보이는 단면도이고, 첨부도면 제3도는 본 고안에 따른 자동차의 공명기를 보이는 사시도로서, 이에 도시한 바와 같이 자동차의 공명기(10)를 배기가스 입구측(30)과 배출구측(40)을 길이 방향으로 구획하도록 다수개의 구멍(13)을 천공한 충돌판(12)에 서로 엇갈리는 방향으로 복수개의 차단판(14)을 충돌판(12)의 양끝단에 형성하여 테일파이프 내부에 융착시키도록 한다.2 is a cross-sectional view showing a resonator of a tail pipe of a vehicle according to the present invention, and FIG. 3 is a perspective view showing a resonator of a vehicle according to the present invention, and as illustrated therein, the resonator 10 of the vehicle is exhausted. The impingement plate 12 has a plurality of blocking plates 14 in a direction intersecting the impingement plate 12 having a plurality of holes 13 perforated so as to partition the gas inlet side 30 and the outlet side 40 in the longitudinal direction. It is formed at both ends of the end to be fused inside the tail pipe.

상기 충돌판(12)과 그 양끝단에 형성시킨 차단판(14)은 완곡부(15)를 형성하여 배출가스의 흐름을 향상시키도록 형성하여, 상기 차단막(14)에 길이는 충돌판(12)을 다수개 설치할 수 있는 길이로 형성하도록 한다.The impingement plate 12 and the blocking plate 14 formed at both ends thereof are formed to form a curved portion 15 to improve the flow of the exhaust gas, and the impingement plate 12 having a length in the blocking film 14. ) To a length that allows multiple installations.

상기 형성된 자동차의 공명기(10)를 테일파이프(25)에 융착시키도록 한다.The resonator 10 of the formed vehicle is to be fused to the tail pipe 25.

이상에서와 같은 본 고안의 실시예에 따른 작용효과를 상세히 설명한다.It will be described in detail the effect according to the embodiment of the present invention as described above.

소음기(20) 후단에 설치된 테일파이프(25)에 공명기(10)를 설치하면, 배출가스는 소음기(20)에 의해 소음이 줄어들게 되고, 상기 줄어든 소음은 배기가스 입구측(30)의 차단판(14)과 배출구측(40)의 차단판(14)에 부딪치게 되며, 완곡부(15)에 의하여 충돌판(12)에 다수개 천공시킨 구멍(13)을 통과하게 된다.When the resonator 10 is installed in the tail pipe 25 installed at the rear end of the silencer 20, the exhaust gas is reduced by the silencer 20, and the reduced noise is blocked by the blocking plate of the exhaust gas inlet side 30 ( 14) and the blocking plate 14 of the discharge port side 40, and passes through the hole 13, which is punched in the collision plate 12 by the curved portion 15.

이때, 충돌판(12)에 다수개 천공시킨 구멍(13)에 의해 음파는 서로 충돌하게 되고, 이로인해 소음은 줄어들어 자동차의 외부로 배출된다.At this time, the sound waves collide with each other by the holes 13 drilled in the collision plate 12, thereby reducing the noise is discharged to the outside of the vehicle.

이와 같이 본 고안은 배기가스 입구측과 배출구측을 길이 방향으로 구획하도록 다수개의 구멍을 천공한 충돌판에 서로 엇갈리는 방향으로 완곡부를 두고 복수개의 차단판을 충돌판의 끝단에 형성하여 테일파이프 내부에 융착시키면, 충돌판에 천공된 구멍에 의하여 소음을 줄일 수 있고, 이에 따라 승차감을 향상시키는 효과가 있는 것이다.As such, the present invention has a plurality of blocking plates formed at the end of the collision plate with a bent portion in a direction crossing each other on a collision plate having a plurality of holes formed so as to partition the exhaust gas inlet side and the outlet side in the longitudinal direction. By fusion, the noise can be reduced by the holes drilled in the collision plate, thereby improving the riding comfort.
