Abstract

A rubber seal is provided to minimize the influence of vibration transmitted from an intake pipe to the rubber seal and applied to the surface of a panel, by reducing the contact area between the surface of the panel and the rubber seal. A rubber seal(100') joins an intake pipe(200') formed integrally with a resonator to a panel(400). The rubber seal is arranged to cover the circumference of the end of the intake pipe and guide the intake pipe to the panel. The rubber seal has a contact protrusion(130) which is compressed against the surface of the panel so as to prevent noise caused due to vibration transmitted through the intake pipe. A recess(120) is formed between two contact protrusions.

본 발명은 레조네이터와 일체로 연결된 흡기관을 판넬과 결합시키는 러버실에 관한 것으로서, 특히 흡기관을 통해 전달되는 진동에 의한 소음을 방지할 수 있는 진동소음방지 러버실에 관한 것이다.The present invention relates to a rubber chamber that couples an intake pipe integrally connected with a resonator to a panel, and more particularly, to a vibration noise preventing rubber room that can prevent noise caused by vibration transmitted through an intake pipe.

레조네이터(RESONATOR)는 자동차의 인테이크 매니폴드(INTAKE MANIFOLD)로 공급되는 공기의 흡기관에서 발생하는 진동에 따른 소음을 감소하기 위한 장치이다. 이러한 레조네이터는 진동과 관련된 특정 주파수를 공진시켜 제거하는 역할을 하는데, 통상적으로 흡기관과 결합되어 있다. 이러한 흡기관은 엔진룸으로 연결되는데, 이 때 엔진룸 표면과 같은 차량에 적용되는 판넬(PANEL)과 결합되게 된다. The resonator is a device for reducing noise caused by vibration generated in the intake pipe of the air supplied to the intake manifold of the vehicle. Such a resonator serves to resonate and remove a specific frequency associated with vibration, and is typically associated with an intake pipe. These intake pipes are connected to the engine compartment, which is combined with a panel applied to the vehicle such as the engine compartment surface.

도 1을 참조하면, 레조네이터(300)가 결합된 흡기관(200)이 판넬(400)에 결합되어 있으며, 판넬(400)과 흡기관(200)의 끝단 사이에는 러버실(100)이 위치하여 진동에 의한 소음을 줄이는 역할을 한다. Referring to FIG. 1, the intake pipe 200 to which the resonator 300 is coupled is coupled to the panel 400, and the rubber chamber 100 is positioned between the panel 400 and the end of the intake pipe 200. It serves to reduce noise caused by vibration.

도 2를 참조하면, 종래의 기술에 의한 러버실(100)은 판넬(400)과 압착되게 된다. 도 2의 점선으로 표시한 부분은 판넬(400)과 압착되기 전의 상태를 나타내고, 러버실(100)이 판넬(400)에 압착될 때, 'A' 만큼의 변위가 발생하면서 판넬(400)과 면접촉을 하게 된다. 이와 같은 러버실(100)은 흡기관 결합부(210)를 통해 흡기관(200)과 결합되는데, 흡기관(200)을 통해 유입되는 공기의 유동에 따라 흡기관(200)이 진동하게 되고, 이러한 진동은 러버실(100)로 전달된다. 따라서, 러버실(100)과 판넬(400)의 접촉면이 넓을 수록 이러한 진동은 판넬(400)로 상당한 정도 전달되어 불필요한 소음을 발생시키는 것이다. 'A'와 같은 변위는 통상적으로 2 밀리미터로 형성된다. Referring to FIG. 2, the rubber chamber 100 according to the related art is compressed with the panel 400. 2 indicates the state before the panel 400 is pressed against the panel 400, and when the rubber chamber 100 is pressed against the panel 400, a displacement of 'A' is generated while the rubber chamber 100 is pressed against the panel 400. There is surface contact. Such a rubber chamber 100 is coupled to the intake pipe 200 through the intake pipe coupling portion 210, the intake pipe 200 is vibrated in accordance with the flow of air flowing through the intake pipe 200, This vibration is transmitted to the rubber chamber (100). Therefore, the wider the contact surface between the rubber chamber 100 and the panel 400 is, the greater the vibration is transmitted to the panel 400 to generate unnecessary noise. Displacements such as 'A' are typically formed in 2 millimeters.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로서, 흡기관의 끝단 둘레를 감싸면서 결합되어 판넬로 흡기관을 안내함과 동시에, 판넬 표면과 압착되는 접촉돌출부가 일체로 형성되어 흡기관을 통해 전달되는 진동에 의한 소음을 방지할 수 있는 진동소음방지 러버실을 제공하는 것을 목적으로 한다.The present invention has been made in view of the above problems, and is coupled to surround the end of the intake pipe to guide the intake pipe to the panel, and at the same time, the contact projection is pressed into the panel surface is formed integrally through the intake pipe An object of the present invention is to provide an anti-vibration rubber chamber that can prevent noise caused by vibrations transmitted.

상기와 같은 목적을 달성하기 위해 제공되는 본 발명에 따른 진동소음방지 러버실은, 레조네이터와 일체로 연결된 흡기관을 판넬과 결합시키는 러버실에 있어서, 상기 러버실은 상기 흡기관의 끝단 둘레를 감싸면서 결합되어 상기 판넬로 상기 흡기관을 안내함과 동시에, 상기 판넬 표면과 압착되는 접촉돌출부가 일체로 형성되어 상기 흡기관을 통해 전달되는 진동에 의한 소음을 방지할 수 있는 것을 특징으로 한다.The anti-vibration rubber chamber according to the present invention provided to achieve the above object, in the rubber chamber for coupling the intake pipe integrally connected to the resonator with the panel, the rubber seal is coupled while wrapping around the end of the intake pipe And guide the intake pipe to the panel, and at the same time, a contact protrusion formed by the panel surface is integrally formed to prevent noise caused by vibration transmitted through the intake pipe.

상기 접촉돌출부는 두 개로 형성되고 상기 두 개의 접촉돌출부 사이에 오목부가 형성된 것이 바람직하다.Preferably, two contact protrusions are formed and a recess is formed between the two contact protrusions.

또한, 상기 접촉돌출부와 오목부는 연속적으로 교차되면서 복수로 형성되는 것이 바람직하다.In addition, it is preferable that a plurality of contact protrusions and recesses are formed while crossing successively.

이하 도 3을 참조하여, 본 발명에 따른 진동소음방지 러버실의 구성에 대하여 상세하게 설명한다. 다만, 도 1 및 도 2에서 설명한 구성요소와 동일한 구성요 소에 대해서는 동일한 부호를 사용하고 이에 대한 설명은 생략한다. Hereinafter, with reference to FIG. 3, the structure of the anti-vibration rubber chamber according to the present invention will be described in detail. However, the same reference numerals are used for the same components as those described in FIGS. 1 and 2, and description thereof will be omitted.

도 3을 참조하면, 본 발명에 따른 진동소음방지 러버실(100')은 흡기관(200')의 끝단 둘레를 감싸면서 결합되어 판넬(400)을 향하여 흡기관(200')을 안내함과 동시에, 판넬(400)의 표면에 압착되는 접촉돌출부(130)가 일체로 형성되어 있다. 여기서 흡기관(200')의 끝단이란 러버실(100')이 결합되는 흡기관 결합부(210')가 형성된 위치를 의미하며, 러버실 결합부(110)와 흡기관 결합부(210')는 상호 맞물리면서 결합된다. Referring to FIG. 3, the anti-vibration rubber chamber 100 ′ according to the present invention is coupled to surround the end of the intake pipe 200 ′ and guides the intake pipe 200 ′ toward the panel 400. At the same time, the contact protrusion 130 pressed against the surface of the panel 400 is integrally formed. Here, the end of the intake pipe 200 'means a position where the intake pipe coupling portion 210' to which the rubber chamber 100 'is coupled is formed, and the rubber seal coupling portion 110 and the intake pipe coupling portion 210' are formed. Are interlocked and combined.

도 3에서 점선으로 표시한 부분은 러버실(100')이 판넬(400)에 압착되기 전의 상태를 나타내며, 러버실(100')이 판넬(400)에 압착되면 'B' 만큼의 변위가 발생하면서 판넬(400)을 압착하게 된다. 이러한 변위는 0.8 밀리미터로 감소된다. 이 때, 러버실(100')에 형성된 접촉돌출부(130)가 판넬(400)을 가압하게 된다. 이 경우, 러버실(100')과 판넬(400)의 접촉은 접촉돌출부(130)에 의해 선접촉으로 한정되어, 흡기관(200')으로 유입되는 공기의 유동에 의해 흡기관(200')에 발생하는 진동이 러버실(100')로 전달되고 다시 판넬(400)로 전달되는 과정에서 상당량 감소하게 된다. 이러한 접촉돌출부(130)는 두 개로 형성되고 두 개의 접촉돌출부 사이에 오목부(120)가 형성된다. 이러한 접촉돌출부(130)와 오목부(120)는 연속적으로 교차되면서 복수로 형성될 수도 있을 것이다. 이는 설계자의 의도에 따라 진동소음을 방지할 수 있는 최적의 수로 결정될 수 있을 것이다. In FIG. 3, a portion indicated by a dotted line indicates a state before the rubber chamber 100 'is pressed onto the panel 400. When the rubber chamber 100' is pressed against the panel 400, a displacement of 'B' is generated. While pressing the panel 400. This displacement is reduced to 0.8 millimeters. At this time, the contact protrusion 130 formed in the rubber chamber 100 ′ presses the panel 400. In this case, the contact between the rubber chamber 100 'and the panel 400 is limited to the line contact by the contact protrusion 130, and the intake pipe 200' is caused by the flow of air flowing into the intake pipe 200 '. Vibration is generated in the rubber chamber 100 'and is transmitted to the panel 400 is reduced in a considerable amount in the process. Two such contact protrusions 130 are formed and a recess 120 is formed between the two contact protrusions. The contact protrusion 130 and the concave portion 120 may be formed in a plurality while being continuously crossed. This may be determined as the optimal number that can prevent vibration noise according to the designer's intention.

이상에서 설명한 본 발명에 따른 진동소음방지 러버실은 판넬 표면과 러버실이 압착될 때의 접촉면적을 줄일 수 있으므로 흡기관에서 러버실로 전달되는 진동이 판넬 표면에 가하는 영향을 최소화하여 그로부터 발생하는 진동소음을 방지할 수 있는 효과가 있다.The anti-vibration rubber chamber according to the present invention described above can reduce the contact area when the panel surface and the rubber chamber are squeezed, thereby minimizing the effect of the vibration transmitted from the intake pipe to the rubber chamber on the panel surface, resulting in vibration noise There is an effect that can prevent.
