도면에 보인 바와 같이, 본 발명의 저주파 실내소음 방지장치는 통상적으로 차 내부에 설치된 엔진 콘트롤 유니트(110)가 차속과 도어 윈도우 글라스(도시하지 않음) 및 트렁크 리드(1)의 개폐를 감지하도록 구성되며, 그 엔진 콘트롤 유니트(110)에 의해 선택적으로 작동되어 차체(2)의 저주파 실내소음을 방지할 수 있도록 트렁크 리드(1)와 차체(2) 사이에 방진부재(120)가 설치된다.As shown in the figure, the low-frequency indoor noise prevention device of the present invention is typically configured so that the engine control unit 110 installed inside the vehicle detects the opening and closing of the vehicle speed and the door window glass (not shown) and the trunk lid 1. The dustproof member 120 is installed between the trunk lid 1 and the vehicle body 2 so as to be selectively operated by the engine control unit 110 to prevent low-frequency indoor noise of the vehicle body 2.
상기 엔진 콘트롤 유니트(110)는 도어 윈도우 글라스 및 트렁크 리드(1)가 닫혀 있고 차속이 시속 60㎞이하 되는 경우에 방진부재(120)를 작동시키도록 구성된다.The engine control unit 110 is configured to operate the dustproof member 120 when the door window glass and the trunk lid 1 are closed and the vehicle speed is 60 km per hour or less.
상기 방진부재(120)의 구성을 살펴보면, 신축성의 방진 몸체(121) 내부 일정 공간(121a)안에 왁스와 같은 열 팽창물질(122)이 충전(充塡)되어 있고 그 열 팽창물질에는 열선(123)이 내장되어 있다.Looking at the configuration of the anti-vibration member 120, a thermal expansion material 122, such as wax is filled in a predetermined space 121a inside the elastic dustproof body 121, and the hot wire 123 in the thermal expansion material. ) Is built in.
방진 몸체(121)의 상부에는 트렁크 리드(1)에 고정하기 위한 걸고리(124)가 형성된다.At the top of the dustproof body 121, a hook 124 for fixing to the trunk lid 1 is formed.
상기 방진 몸체(121) 내부에 승하강 부재(125)가 설치되며, 그 승하강 부재(125)는 열 팽창물질에 의해 선택적으로 승하강 되면서 방진 몸체(121)의 하부를 신장시키도록 구성된다.The elevating member 125 is installed inside the dustproof body 121, and the elevating member 125 is configured to extend the lower portion of the dustproof body 121 while being selectively elevated by the thermal expansion material.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
시동 후 엔진 콘트롤 유니트(110)가 차속과 도어 윈도우 글라스 및 트렁크 리드(1)의 개폐를 감지한다.After starting, the engine control unit 110 detects opening and closing of the vehicle speed and the door window glass and the trunk lid 1.
상기 엔진 콘트롤 유니트(110)의 감지 결과, 상기 도어 윈도우 글라스 및 트렁크 리드(1)가 닫혀 있고 차속이 시속 60㎞이하 되는 경우 엔진 콘트롤 유니트(110)는 트렁크 리드(1)와 차체(2) 사이에 설치된 방진부재(120)에 전원(130)을 인가한다.As a result of the detection of the engine control unit 110, when the door window glass and the trunk lid 1 are closed and the vehicle speed is 60 km / h or less, the engine control unit 110 is disposed between the trunk lid 1 and the vehicle body 2. The power supply 130 is applied to the dustproof member 120 installed in the.
전원(130)이 방진부재(120)에 공급되면, 열선(123)이 가열되면서 방진 몸체(121)에 있는 왁스(122)를 팽창시킨다(도2의 실선으로 표시).When the power supply 130 is supplied to the dustproof member 120, the heating wire 123 is heated to expand the wax 122 in the dustproof body 121 (indicated by the solid line in FIG. 2).
이때 왁스(122)의 팽창에 의해서 승하강 부재(125)가 하강하면서 방진 몸체(121)의 하부를 팽창시킨다.At this time, the lowering member 125 is expanded by the expansion of the wax 122 while expanding the lower portion of the dustproof body 121.
방진 몸체(121)의 팽창에 의해서 트렁크 리드(1)와 차체(2) 사이의 유격이 제거됨으로써 차체(2)의 저주파 실내소음을 방지할 수 있는 것이다.The clearance between the trunk lid 1 and the vehicle body 2 is removed by the expansion of the dustproof body 121, thereby preventing low-frequency indoor noise of the vehicle body 2.
도 3은 본 발명의 기술을 적용 한 후의 실내소음 측정치를 보인 그래프이다.Figure 3 is a graph showing the measured room noise after applying the technology of the present invention.
도 3에 보인 바와 같이, 가로축은 엔진회전수를 보인 것이고 세로축은 실내소음을 보인 것이며, 실선은 종래 실험치이고 파선은 본 발명의 실험치를 보인 것이다.As shown in Figure 3, the horizontal axis shows the engine speed and the vertical axis shows the room noise, the solid line is the conventional experimental value and the broken line is the experimental value of the present invention.
엔진회전수 2400 rpm이하 구간에서는 본 발명을 적용 후 저속에서의 저주파 실내소음이 2-6 dB 정도 개선됨을 알 수 있었다.In the engine speed of 2400 rpm or less, low-frequency indoor noise at low speed was improved by 2-6 dB after applying the present invention.
이와 같이 본 발명에 의하면, 자동차 저속 주행 시 엔진 콘트롤 유니트가 자동으로 이를 감지함과 동시에 트렁크 리드와 차체 사이에 설치된 방진부재를 팽창시켜서 트렁크 리드와 차체와의 유격을 없애 저주파 실내소음을 사전에 제거하여 저속 주행 시 부밍 현상 및 로드 소음을 효과적으로 방지할 수 있다.As described above, according to the present invention, the engine control unit automatically detects this when driving at low speeds of the vehicle and expands the dustproof member installed between the trunk lid and the vehicle body to eliminate the clearance between the trunk lid and the vehicle body, thereby removing low-frequency indoor noise in advance. Therefore, it can effectively prevent the booming phenomenon and the road noise at low speed.
