본 발명은 소음저감용 공명기에 관한 것으로, 특히 공명기의 연결관 면적을 가변시킬 수 있도록 하여 공명효과를 향상시킬 수 있도록 된 자동차의 흡기소음저감용 가변식 공명기에 관한 것이다.The present invention relates to a resonator for noise reduction, and more particularly, to a variable resonator for intake noise reduction of a vehicle that can improve the resonance effect by varying the connection pipe area of the resonator.
자동차의 흡기매니폴트에는 외기가 기관으로 유입되면서 발생되는 각종 소음중 특정한 주파수 영역을 갖는 소음을 저감시켜주도록 된 공명기가 설치되어 있는바, 통상 이러한 공명기는 몸체의 면적과 덕트와 연결하는 연결관길이 및 이 연결관의 면적을 적절히 조절함으로써 공명시키고자 하는 주파수범위를 설정하게 된다.The air intake manifold of the car is equipped with a resonator designed to reduce noise having a specific frequency range among various noises generated by the inflow of outside air into the engine. In general, such a resonator has a connection length connecting the area of the body and the duct. And by appropriately adjusting the area of the connector, the frequency range to be resonated is set.
한편, 상기와 같은 종래의 공명기는 보통 일정한 칫수로 제조됨에 따라 일정구역의 주파수에 대해서만 감응하게 되어, 예컨대 공명시키고자 하는 주파수영역이 다수개일 때에는 각가의 주파수영역에 감응되는 공명기를 다수개 설치하여야 한다는 결점이 있다.On the other hand, the conventional resonator as described above is usually manufactured only in a certain dimension, so as to respond only to the frequency of a certain area, for example, when there are a plurality of frequency region to be resonated, a plurality of resonators sensitive to each frequency region should be installed There is a drawback.
이에따라 최근에는 공명기의 유입통로길이를 조절하도록 하여 공명 주파수범위를 확장시키도록 된 것이 제안되어 있는바, 즉 제 3도에 도시된 것과 같이 덕트(30)에 소정형상으로 이루어지면서 유입통로(31)에 솔레노이드밸브(32)를 매개로 작동되는 셔터밸브(33)를 다수개 설치한 공명기(34)를 분지연결하여, 상기 솔레노이드밸브(22) 를 엔진의 회전수에 따라 선택적으로 작동시켜 셔터밸브(33)가 개폐되도록 하여 공명기로 전달되는 진동이나 소음등의 유입통로길이를 적절히 조절하여 줌으로써, 비교적 넓은 영역의 주파수에 대해 공명감응될 수 있도록 되어 있다.Accordingly, in recent years, it has been proposed to extend the resonant frequency range by adjusting the inflow path length of the resonator, that is, the inflow path 31 is formed in a predetermined shape in the duct 30 as shown in FIG. The resonator 34, which is provided with a plurality of shutter valves 33 operated through the solenoid valve 32, is branch-connected, and the solenoid valve 22 is selectively operated according to the engine speed. 33) is opened and closed to adjust the length of the inflow path such as vibration and noise transmitted to the resonator, so that the resonance can be sensed for a relatively wide frequency range.
그러나 이같은 구조로 된 종래의 공명기는 유입통로(31)를 개폐시키기 위한 개폐수단이 다수개 필요할 뿐 아니라, 이같은 개폐수단을 동작시키기 위한 별도의 제어기구를 필요할 뿐 아니라, 이같은 개폐수단을 동작시키기 위한 별도의 제어기구를 각각의 개폐수단과 연결시켜야 함에 따라 구조가 복잡해지게 되는 등의 결점이 있었다.However, the conventional resonator having such a structure requires not only a plurality of opening and closing means for opening and closing the inflow passage 31, but also a separate control mechanism for operating such opening and closing means, and for operating such opening and closing means. As a separate control mechanism must be connected to each opening and closing means, the structure is complicated.
이에 본 발명은 상기와 같은 결점을 해결하기 위하여 발명된 것으로 1개의 구동수단으로 공명기의 연결부 단면적을 선택적으로 변화시킬 수 있도록 하여 구조가 간단할 뿐 아니라, 여러영역의 주파수에 공명감응토록 구성된 자동차의 흡기소음저감용 가변식 공명기를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above-mentioned drawbacks, and the structure of the vehicle is not only simple by allowing one drive unit to selectively change the cross-sectional area of the connection part of the resonator, and is configured to resonate in the frequency of various regions. An object of the present invention is to provide a variable resonator for reducing intake noise.
상기와 같은 목적을 달성하기 위한 본 발명은 몸체의 입구측에 간막이판을 사이에 두고 2개 또는 2개이상의 유입통로가 분할형성됨과 더불어 상기 간만이판의 어느 한쪽에 원판형상을 하면서 소정크기로 형성된 통로를 갖춘 회전봉이 소정의 구동수단을 매개로 좌우로 회전가능하도록 회전축에 끼워진 구조로 되어 있다.The present invention for achieving the above object is divided into two or two or more inlet passages formed between the partition plate at the inlet side of the body as well as the disc shape on any one side of the bay plate to a predetermined size The rotating rod having the formed passage is structured to be fitted to the rotating shaft so as to rotate left and right through a predetermined driving means.
이하 본 발명을 첨부 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1도 (a) (b)는 각각 본 발명에 따른 사용상태 단면도를 도시한 것이고, 제 2도(a)(b)는 제 1도를 따른 단면도인바, 연결부(1)에 소정길이로 평행하게 형성된 간막이(2)와 반원형 간막이(4)가 각각 독립되어 설치되어, 반원형상을 하면서 일측에 소정크기로 통로(5)가 형성되어 상기 간막이(4)에 일치됨과 더불어 회전축(6)에 끼워진 회전봉(7)이 몸체(8)에 내장된 공명기(9)가 흡입덕트(10)의 소정위치에 분지연결되어 있는 한편, 상기 회전봉(7)은 별도의 구동수단, 예컨대 레버(도시 안됨)등을 매개로 엔진회전수 또는 엔진부하에 따른 부압에 동조되도록 상호 전기적으로 연결된 구조로 되어 있다.1 (a) and (b) show cross-sectional views of a state of use in accordance with the present invention, respectively, and FIGS. 2 (a) and (b) are cross-sectional views taken along the first view and are parallel to the connecting portion 1 with a predetermined length. The diaphragm 2 and the semicircular diaphragm 4 each formed separately are installed separately, and the passage 5 is formed on one side with a semicircular shape so as to coincide with the diaphragm 4 and fitted to the rotating shaft 6. A resonator 9 having a rotary rod 7 embedded in the body 8 is branched at a predetermined position of the suction duct 10, while the rotary rod 7 has a separate driving means, such as a lever (not shown). It has a structure that is electrically connected to each other so as to be synchronized to the negative pressure according to the engine speed or the engine load through the.
이에따라 상기한 구조로 이루어진 흡기소음저감용 가변식 공명기는, 상기 회전봉(7)에 형성된 통로(5)를 매개로 제 1입구통로(11)와 제 2입구통로(12)로 분할형성된 연결부(1)중 제 2입구통로(12)를 선택적으로 개폐시킴으로써 연결부(1)이 유효단면적을 변화시켜 다수의 주파수영역에 대한 공명감응효과를 발휘할 수 있게 되는바,즉 공명시키고자 하는 주파수영역이 제 1입구통로(11)만의 유효단면적으로 감응할 수 있는 경우, 상기 회전봉(7)의 통로(5)를 제 1도(a)에 도시된 것과 같이 동작시켜 제 2입구통로(12)를 닫아주고, 반면에 공명시키고자 하는 주파수영역을 상기 제 1입구통로(11)와, 제 2입구통로(12)를 합한 유효단면적으로 감응시킬 수 있는 경우에는, 상기 회전봉(7)을 동작시켜 통로(5)를 열어 주기만 하면 된다.Accordingly, the variable resonator for reducing the intake noise having the above-described structure is connected to the first inlet passage 11 and the second inlet passage 12 through the passage 5 formed in the rotary rod 7. By selectively opening and closing the second inlet passage 12, the connecting portion 1 can change the effective cross-sectional area to exert a resonance-sensing effect on a plurality of frequency domains. When the effective cross section of the inlet passage 11 can be sensed, the passage 5 of the rotary rod 7 is operated as shown in FIG. 1 (a) to close the second inlet passage 12, On the other hand, when the frequency region to be resonated can be sensed by the effective cross-sectional area of the first inlet passage 11 and the second inlet passage 12, the rotary rod 7 is operated to pass the passage 5. Just open it.
이상 설명한 것과 같이 본 발명에 의하면, 공명기(9)의 연결부(1)일측에 레버등으로 조작되는 구동기구를 엔진회전수 또는 엔진부하에 따른 부압에 동조되도록 전기적으로 연결시키고, 이 구동기구로 상기 연결부(1)의 유효단면적을 간단하게 가변시키도록 하여 공명기(9)가 다수의 주파수대역에 대해 공명감응되도록 함으로써, 간단한 구조로 공명감응영역을 확대시킬 수 있는 효과가 있게 된다.As described above, according to the present invention, a drive mechanism operated by a lever or the like is connected to one side of the connecting portion 1 of the resonator 9 so as to be electrically connected to the negative pressure according to the engine speed or the engine load. By simply varying the effective cross-sectional area of the connecting portion 1 so that the resonator 9 is resonance-sensitized for a plurality of frequency bands, there is an effect that the resonance-sensing area can be expanded with a simple structure.
