Description

자동차용 익스트랙터{Automobile extractor}Automotive extractor {Automobile extractor}

본 발명은 도어를 닫을 때 실내의 압력이 높아지는 것을 방지시키기 위한 자동차용 익스트랙터(extractor)에 관한 것이다.The present invention relates to an automotive extractor for preventing the interior pressure from increasing when the door is closed.

도 1에 도시된 바와 같이, 이러한 익스트랙터(10)는 자동차의 리어 범퍼 내측의 사이드 패널에 설치되어 있다. 도 2 및 도 3에 보다 상세하게 도시된 바와 같이, 익스트랙터는 사이드 패널(1)에 형성된 장착공에 설치되고 자동차의 실내와 실외를 소통하기 위한 소통공(13)이 형성된 프레임(12)과, 자동차의 실외측에서 프레임(12)의 소통공(13)을 개폐하는 고무판(14)을 포함하고 있다. 고무판(14)은 리벳이나 볼트와 같은 고정구(15)에 의해 그 상단이 프레임(12)의 소통공(13) 상측에 고정되어 있다.As shown in FIG. 1, such an extractor 10 is provided in a side panel inside a rear bumper of a vehicle. As shown in more detail in FIGS. 2 and 3, the extractor is installed in a mounting hole formed in the side panel 1 and has a frame 12 formed with a communication hole 13 for communicating the interior and exterior of a vehicle. And a rubber plate 14 for opening and closing the communication hole 13 of the frame 12 on the outdoor side of the vehicle. The upper end of the rubber plate 14 is fixed to the upper side of the communication hole 13 of the frame 12 by a fastener 15 such as a rivet or a bolt.

탑승자가 자동차의 도어를 열었다 닫을 때 자동차 실내의 공기는 압축된다. 이에 따라 고무판(14) 양측에서 압력차가 발생된다. 즉, 실내의 압력이 실외의 압력보다 높아지는 것이다. 그 결과, 고무판(14)은 실내 공기의 압력에 의해, 도 3에 도시된 바와 같이, 그 하단이 후방으로 밀려서 프레임(12)의 소통공(13)이 개방되고 자동차 실내의 공기는 소통공(13)을 통해 외부로 배출된다.When the occupant opens and closes the door of the car, the air inside the car is compressed. As a result, a pressure difference is generated at both sides of the rubber plate 14. In other words, the indoor pressure is higher than the outdoor pressure. As a result, the rubber plate 14 is pushed backward by the pressure of the indoor air, and as shown in FIG. 13) is discharged to the outside.

그러나, 상기와 같은 종래의 자동차의 익스트랙터는 다음과 같은 단점이 있었다.However, the above-described extractor of a conventional vehicle has the following disadvantages.

즉, 자동차가 고속 주행을 할 경우 익스트랙터 후방의 실외 공기의 압력이 대기압보다 크게 낮아지는 경우가 종종 발생된다. 이에 비하여 자동차의 실내 공기의 압력은 대기압으로 유지되기 때문에, 이 압력차에 의해 익스트랙터의 고무판이 실외측으로 밀려 소통공이 개방되는 경우가 발생된다. 이에 따라, 먼지와 같은 이물질 또는 소음이 실외로부터 소통공을 통해 실내로 유입되는 문제점이 있다. 또한, 자동차의 주행에 따라 고무판이 반복적으로 소통공을 개폐하면서 프레임과 부딪쳐 발생되는 소위 래틀음(rarrle noise)라는 소음도 문제가 된다.In other words, when the vehicle is traveling at high speed, the pressure of the outdoor air behind the extractor is often lower than atmospheric pressure. On the other hand, since the pressure of the indoor air of the vehicle is maintained at atmospheric pressure, the pressure difference causes the rubber plate of the extractor to be pushed to the outdoor side, whereby a communication hole is opened. Accordingly, there is a problem that foreign matter or noise such as dust is introduced into the room through a communication hole from the outside. In addition, as the rubber plate repeatedly opens and closes the communication hole as the vehicle runs, so-called rattle noise generated by hitting the frame also becomes a problem.

본 발명은 상기와 같은 점들을 감안하여 안출된 것이다. 본 발명의 목적은 자동차의 주행에 따른 압력차로 인해 소통공이 개폐되는 것을 방지할 수 있는 자동차용 익스트랙터를 제공하는데 있다.The present invention has been made in view of the above points. An object of the present invention is to provide an automotive extractor that can prevent the communication hole is opened and closed due to the pressure difference according to the driving of the vehicle.

상기와 같은 목적은, 실내측 개구와 실외측 개구를 가지며, 차체의 후방에 설치되는 관형상의 프레임; 프레임의 실외측 개구에 수평하게 설치되는 회전축과 회전축의 상, 하측에 각각 고정되는 상, 하부판을 가지며, 하부판은 상부판보다 무거운 개폐 부재; 및 프레임의 내부를 상부판에 의해 개폐되고 실내측 개구와 소통하는 상측 공간과, 하부판에 의해 개폐되고 실내측 개구와는 소통하지 않는 하측 공간으로 구획하는 구획 부재를 포함하는 본 발명에 따른 자동차용 익스트랙터에 의해 달성된다.The above object is a tubular frame having an indoor side opening and an outdoor side opening, which is installed at the rear of the vehicle body; A rotating shaft installed horizontally in the outdoor opening of the frame and upper and lower plates respectively fixed to upper and lower sides of the rotating shaft, the lower plate including an opening and closing member that is heavier than the upper plate; And a partition member for partitioning an interior of the frame into an upper space opened and closed by an upper plate and communicating with an interior side opening, and a lower space opened and closed by a lower plate and not communicating with an interior opening. This is achieved by an extractor.

바람직하게는, 개폐 부재의 상부판과 하부판은 실내측을 향해 소정각도로 각각 경사지게 형성되어 있으며, 하부판의 하단에는 중량추가 형성된다.Preferably, the upper plate and the lower plate of the opening and closing member are formed to be inclined at a predetermined angle toward the interior side, respectively, and the weight is formed at the lower end of the lower plate.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 4는 본 발명의 일 실시예에 따른 자동차용 익스트랙터를 도시한 사시도고, 도 5는 본 발명에 따른 익스트랙터의 단면도다.Figure 4 is a perspective view showing an automotive extractor according to an embodiment of the present invention, Figure 5 is a cross-sectional view of the extractor according to the present invention.

도 4 및 도 5에 도시된 바와 같이, 본 발명의 일 실시예에 따른 자동차용 익스트랙터는 중공관 형상의 프레임(110)과, 개폐 부재(120)와, 구획 부재(130)를 포함하고 있다.As shown in FIGS. 4 and 5, an automotive extractor according to an embodiment of the present invention includes a hollow tube-shaped frame 110, an opening and closing member 120, and a partition member 130. .

프레임(110)은 자동차의 리어 범퍼 내측의 사이드 패널(미도시)에 형성된 장착공에 설치되어 있으며, 자동차의 실내와 소통하는 실내측 개구와 자동차의 실외와 소통하는 실외측 개구를 가진다.The frame 110 is installed in a mounting hole formed in a side panel (not shown) inside the rear bumper of the vehicle, and has an interior side opening communicating with the interior of the vehicle and an outdoor side opening communicating with the exterior of the vehicle.

개폐 부재(120)는 수평하게 설치되는 회전축(121)과, 회전축(121)의 상부에 고정된 상부판(123)과, 회전축(121)의 하부에 고정된 하부판(125)을 포함하며, 프레임(110)의 실외측 개구를 막도록 설치되어 있다. 하부판(125)은 상부판(123)에 비해 무겁게 형성되며, 바람직하게는 그 하단에 중량추(126)가 구비되어 있다. 또한, 바람직하게는 상부판(123)과 하부판(125)은 프레임(110)의 내부을 향해 소정 각도로 각각 경사져 있다.The opening and closing member 120 includes a rotating shaft 121 that is horizontally installed, an upper plate 123 fixed to the upper portion of the rotating shaft 121, and a lower plate 125 fixed to the lower portion of the rotating shaft 121. It is provided so as to close the outdoor side opening of the 110. The lower plate 125 is formed heavier than the upper plate 123, and preferably has a weight 126 at its lower end. In addition, preferably, the upper plate 123 and the lower plate 125 are inclined at predetermined angles toward the inside of the frame 110, respectively.

구획 부재(130)는 프레임(110)의 내부에 설치되어 프레임(120)의 내부를 상측 및 하측 공간(111, 113)으로 구획한다. 즉, 구획 부재(130)의 일단은 프레임(110)의 내부 저면에 고정되고, 타측은 그 끝이 개폐 부재(120)의 회전축(121) 직전에 위치하도록 연장하고 있다. 이러한 구획 부재(130)에 의해 프레임(110)의 내부는 개폐 부재(120)의 상부판(123)에 의해 개폐되고 자동차의 실내와 소통되는 상측 공간(111)과, 개폐 부재(120)의 하부판(125)에 의해 개폐되고 자동차의 실내와는 소통하지 않는 하측 공간(113)으로 구획된다.The partition member 130 is installed inside the frame 110 to partition the inside of the frame 120 into upper and lower spaces 111 and 113. That is, one end of the partition member 130 is fixed to the inner bottom surface of the frame 110, and the other end thereof extends such that the end thereof is located immediately before the rotation shaft 121 of the opening and closing member 120. The interior of the frame 110 by the partition member 130 is opened and closed by the upper plate 123 of the opening and closing member 120 and the upper space 111 in communication with the interior of the vehicle, and the lower plate of the opening and closing member 120 The lower space 113 is opened and closed by the 125 and does not communicate with the interior of the vehicle.

도면에서, 참조 부호 115는 상측 공간을 보다 확실하게 밀폐하도록 상부판(123)의 상단에 접촉되는 턱이다.In the figure, reference numeral 115 denotes a jaw that contacts the upper end of the top plate 123 to more securely seal the upper space.

개폐 부재(120)가 평형 상태에 있을 때, 즉 자동차의 실내외에 압력차가 없을 때, 개폐 부재(120)의 상부판(123)은 상측 공간(111)의 실외측 개구를 막고 있다. 이 상태에서 도어가 열렸다가 다시 닫히면 자동차의 실내와 소통하는 상측 공간(111)의 공기압은 자동차의 실외측 및 하측 공간(113)의 공기압보다 높아진다. 이에 따라 개폐 부재(120)는 상측 공간(111)의 실외측 개구가 개방되도록 (도면에서 보아 시계 방향으로) 회전된다. 이에 따라 실내 공기는 실외로 배출되어 실내외의 압력차는 해소된다.When the opening / closing member 120 is in an equilibrium state, that is, when there is no pressure difference inside or outside the vehicle, the upper plate 123 of the opening / closing member 120 is blocking the outdoor side opening of the upper space 111. In this state, when the door is opened and closed again, the air pressure of the upper space 111 communicating with the interior of the vehicle is higher than the air pressure of the outdoor side and the lower space 113 of the vehicle. Accordingly, the opening and closing member 120 is rotated (clockwise as seen in the drawing) so that the outdoor side opening of the upper space 111 is opened. Accordingly, indoor air is discharged to the outside, and the pressure difference outside the indoors is eliminated.

자동차가 고속으로 주행하면, 실외의 공기압이 대기압보다 낮아진다. 그러나, 본 발명의 실시예에 있어서는 프레임(110)의 상측 공간(111) 및 하측 공간(113) 모두 대기압으로 유지되기 때문에, 개폐 부재(120)의 상부판(123)과 하부판(125)은 모두 실외측으로 작용하는 힘을 받게된다. 따라서, 실외의 공기압이 실내보다 낮아지더라도 개폐 부재(120)는 회전되지 않아 실외측 개구는 닫힌 상태로 유지된다.When the car runs at high speed, the outdoor air pressure becomes lower than atmospheric pressure. However, in the embodiment of the present invention, since both the upper space 111 and the lower space 113 of the frame 110 is maintained at atmospheric pressure, both the upper plate 123 and the lower plate 125 of the opening and closing member 120 The force acting on the outdoor side. Therefore, even if the outdoor air pressure is lower than the indoor, the opening / closing member 120 is not rotated and the outdoor opening is kept closed.

상기된 바와 같은 본 발명에 따른 익스트랙터는 자동차의 고속 주행에 따른 실외의 공기압 저하에도 개폐 부재가 개방되지 않도록 구성되어 있기 때문에, 실외로부터의 이물질이 실내로 침입하는 것과 소음이 발생되는 것도 방지할 수 있는 장점이 있다.The extractor according to the present invention as described above is configured so that the opening and closing member does not open even when the outdoor air pressure decreases due to the high-speed driving of the vehicle, thereby preventing foreign substances from entering the interior from entering the room and generating noise. There are advantages to it.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below. It may be changed.
