Description

자동차 도어의 웨더 스트립 장치{DOOR WEATHERSTRIP MEANS OF AN AUTOMOBILE}Weather strip device of car door {DOOR WEATHERSTRIP MEANS OF AN AUTOMOBILE}

본 발명은 자동차 도어의 웨더 스트립장치에 관한 것이다.The present invention relates to a weather strip device of an automobile door.

일반적으로 웨더 스트립은 연질 고무로된 튜브 형태로써 자동차 도어의 테두리에 설치되어 자동차 도어와 바디 사이의 실링(sealing)기능을 수행하는 것이다.In general, the weather strip is formed in the form of a tube of soft rubber to the edge of the car door to perform a sealing function between the car door and the body.

이러한 웨더스트립은 통상적으로 튜브 형태로 되고 도어를 닫았을 때 내부의 공기를 빼어내기 위한 통기구멍이 형성되어 있어 자동차 도어와 바디 사이에서 실링 기능을 충분히 수행하지 못하였다.Such weather strips are generally in the form of tubes, and when the doors are closed, vent holes are formed to draw out the air therein, and thus the sealing function is not sufficiently performed between the vehicle door and the body.

즉, 도어가 닫힌 상태에서 도어의 테두리에 설치된 웨더스트립은 단순히 바디에 눌려지므로 웨더스트립과 바디 사이의 실링 기능이 충분하지 못하였다.That is, the weather strip installed on the edge of the door while the door is closed is simply pressed on the body, so that the sealing function between the weather strip and the body was not sufficient.

이러한 문제점을 해결하기 위하여 특허출원 10-1995-0017081호에서와 같이 웨더 스트립 내부에 중공부를 형성한 뒤 도어가 닫힌 상태에서 웨더 스트립의 중공부로 에어를 강제 공급함으로써 이를 팽창시켜 실링 효과를 배가시키는 것이 제안되어 있다.In order to solve this problem, as shown in Patent Application No. 10-1995-0017081, forming a hollow inside the weather strip and inflating the air by supplying air to the hollow of the weather strip while the door is closed to double the sealing effect. It is proposed.

그러나 이러한 웨더스트립장치는, 단순히 도어가 닫힌 상태에서 에어를 주입하여 웨더스트립을 팽창시키는 것이기 때문에 차량의 속도가 일정 이하로 주행할때에는 오히려 불필요한 팽창이 야기됨으로써 웨더스트립이 변형이 야기되고, 팽창된 상태에서 도어를 개방시킬 때 도어의 개방을 저해하는 요인이 된다.However, since the weather strip device simply inflates the weather strip by injecting air with the door closed, the weather strip is deformed due to unnecessary expansion when the vehicle speed is below a certain level, thereby causing the weather strip to deform. When the door is opened in the state, it becomes a factor that inhibits the opening of the door.

또한 고속 주행시에는 차속에 따라 웨더스트립이 변형되어지는 바, 즉, 웨더스트립 내측과 대기중의 압력 차이에 의해 웨더스트립이 변형되기 때문에 틈새가 발생되게 되고, 이를 통해 윈드 노이즈(wind noise)가 유입될 우려가 야기된다.In addition, during high-speed driving, the weather strip is deformed according to the speed of the vehicle. That is, the weather strip is deformed due to the difference in pressure between the inside of the weather strip and the atmosphere, so that a gap is generated, thereby inducing wind noise. Concerns are caused.

따라서 차속에 따라 적절하게 웨더스트립의 중공부에 에어를 주입하거나 또는 주입된 에어를 배출하는 것이 요망되고 있는 실정이다.Therefore, according to the vehicle speed, it is desired to inject air to the hollow portion of the weather strip or to discharge the injected air.

본 발명은 이와같은 종래 웨더스트립 장치의 문제점을 해결하기 위하여 창출된 것으로서, 차속 및 이에따른 웨더스트립 중공부 내측의 압력 변환에 따라 적절하게 에어를 공급하거나 배출시킴으로써 안정된 실링 효과를 얻을 수 있는 자동차 도어의 웨더스트립장치를 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the conventional weather stripping device, and the automobile door which can obtain a stable sealing effect by supplying or discharging air appropriately according to the vehicle speed and the pressure change inside the weather strip hollow part. The purpose of the present invention is to provide a weather strip device.

도 1 및 도 2에서와 같이 본 발명은, 도어 패널(D)에 결합되어 바디 패널(B)에 접촉되며 내부에 중공부(11)를 구비하는 웨더스트립(10)을 구비한다.As shown in FIGS. 1 and 2, the present invention includes a weather strip 10 coupled to the door panel D to be in contact with the body panel B and having a hollow portion 11 therein.

이 웨더스트립(10)상에는 에어를 공급하기 위한 것으로서, 호스(21)를 통해 펌프(20)가 연결된다.The pump 20 is connected to the weather strip 10 to supply air through the hose 21.

그리고 펌프(20)를 통해 웨더스트립(10)에 에어를 공급할 때 역류를 방지하고 일방향으로만 공급될 수 있도록 하기 위하여 체크밸브(30)가 호스(21)의 일단에마련된다.In addition, when supplying air to the weather strip 10 through the pump 20, a check valve 30 is provided at one end of the hose 21 to prevent backflow and to be supplied only in one direction.

한편, 웨더스트립(10)상에는 내부의 에어 압력을 감지하기 위한 압력센서 (40)가 복수 구비되는 바, 특히 이 압력센서(40)는, 웨더스트립(10)의 전방측 상부에 마련된다.On the other hand, the weather strip 10 is provided with a plurality of pressure sensors 40 for sensing the air pressure therein, in particular, the pressure sensor 40 is provided on the upper side of the front side of the weather strip 10.

이와같이 압력센서(40)을 웨더스트립(10)의 전방측 상부에 마련하는 것은, 주행과정에서 웨더스트립(10)의 전방측 상부가 가장 낮은 압력을 갖는 위치이기 때문이다.Thus, the pressure sensor 40 is provided in the upper part of the front side of the weather strip 10 because the upper part of the front side of the weather strip 10 has the lowest pressure in the process of driving.

한편, 웨더스트립(10)의 타측 일면에는 웨더스트립(10)내의 에어를 선택적으로 대기중에 방출시키기 위한 것으로 일방향 배기밸브(50)가 마련된다.Meanwhile, a one-way exhaust valve 50 is provided on the other side of the weather strip 10 to selectively discharge air in the weather strip 10 into the atmosphere.

또한 자동차의 바디 패널(B)상에는 주행하는 자동차의 주행속도를 감지하기 위한 것으로서, 차속센서(60)가 마련된다.In addition, the vehicle speed sensor 60 is provided on the body panel B of the vehicle to detect the traveling speed of the vehicle.

그리고 차속센서(60)에 의한 차량의 주행속도와 압력센서(40)에 의한 웨더스트립(10)내의 압력상태를 감지하여 이를 연산함으로써 선택적으로 펌프(20)를 구동시키거나 배기밸브(50)를 개방시키는 제어기(70)를 구비한다.Then, by detecting the driving speed of the vehicle by the vehicle speed sensor 60 and the pressure state in the weather strip 10 by the pressure sensor 40 and calculating this, the pump 20 may be selectively driven or the exhaust valve 50 may be operated. And a controller 70 for opening.

이때 제어기(70)가 압력센서(40)에 의한 압력상태를 연산하는 시점은 차량의 주행속도가 80㎞/h 이상일 때 행하도록 함이 바람직하다.At this time, the controller 70 preferably calculates the pressure state by the pressure sensor 40 when the traveling speed of the vehicle is 80 km / h or more.

이는 자동차의 주행속도가 80㎞/h 이하일때는 주 소음원이 엔진 및 로드 노이즈가 주 원인이기 때문에 펌프(20)를 작동 시킬 필요가 없고, 반면에 80㎞/h 이상일때에는 주 소음원이 윈드 노이즈(win noise)이기 때문에 펌프(20)를 작동시킬 필요가 있기 때문이다.It is not necessary to operate the pump 20 when the driving speed of the vehicle is 80 km / h or less because the main noise source is mainly caused by engine and road noise, whereas when the vehicle speed is 80 km / h or more, the main noise source is wind noise (win This is because it is necessary to operate the pump 20 because it is noise.

이와같이 구성된 본 발명은, 자동차의 주행속도가 80㎞/h 이하일때에는 제어기(70)가 작동하지 않고 있는 상태이며, 차속센서(60)에 의해 주행속도가 80㎞/h 이상이 되는 것을 감지하게 되면, 제어기(70)는 웨더스트립(10)내의 압력센서(40)의 압력을 체킹한다.According to the present invention configured as described above, when the driving speed of the vehicle is 80 km / h or less, the controller 70 is not operating. When the vehicle speed sensor 60 detects that the driving speed is 80 km / h or more, The controller 70 checks the pressure of the pressure sensor 40 in the weather strip 10.

이때 압력센서(40)중의 어느 하나가 대기압 이하인 것이 판단되면, 이 시점에서 웨더스트립(10)의 변형이 야기되기 때문에 제어기(70)가 이를 판단하여 펌프(20)를 작동시킨다.At this time, if it is determined that any one of the pressure sensor 40 is below the atmospheric pressure, since the deformation of the weather strip 10 is caused at this point, the controller 70 determines this and operates the pump 20.

펌프(20)의 작동에 의해 에어가 체크밸브(30)와 호스(21)를 통해 웨더스트립 (10)내로 에어가 공급되어 웨더스트립(10)이 팽창하면서 실링을 행하게 된다.By the operation of the pump 20, air is supplied into the weather strip 10 through the check valve 30 and the hose 21, and the weather strip 10 expands to perform sealing.

이때 펌프(20)를 통해 공급되는 에어량은, 압력센서(40)에 의해 체킹된 압력과 차속센서(60)에 의해 체킹된 차 속의 제곱을 곱한 값에 상당하는 양을 공급하여야 한다.At this time, the amount of air supplied through the pump 20 should supply an amount corresponding to a value obtained by multiplying the pressure checked by the pressure sensor 40 and the square of the vehicle speed checked by the vehicle speed sensor 60.

이는 도어 패널(D)에 작동하는 흡인력(suction froce)은 속도의 제곱에 비례하여 커지기 때문이다.This is because the suction froce acting on the door panel D increases in proportion to the square of the speed.

한편, 이러한 상태에서 점차적으로 주행속도가 저하되어 80㎞/h 이하로 떨어지게 되면, 제어기(70)가 이를 감지함과 동시에 배기밸브(50)를 개방시켜 웨더스트립(10) 내의 에어를 대기중으로 배출시킨다.On the other hand, when the running speed gradually decreases in this state and falls below 80 km / h, the controller 70 detects this and simultaneously opens the exhaust valve 50 to discharge air in the weather strip 10 to the atmosphere. Let's do it.

이를 통해 웨더스트립(10)은 항상 적정한 압력을 유지하게 되고, 따라서 변형이 야기되지 않으며, 도어의 개방성을 향상시킬 수 있게된다.This ensures that the weather strip 10 always maintains the proper pressure, so that no deformation is caused and the openness of the door can be improved.

이상과 같이 본 발명은, 자동차의 주행속도 및 웨더스트립내의 압력에 따라 적절하게 에어를 공급하거나 배출시킴으로써 안정된 실링 기능을 수행할 수 있는 이점을 갖게되며, 동시에 웨더스트립의 변형이 방지되고 도어의 개폐성을 향상시킬 수 있게된다.As described above, the present invention has the advantage of performing a stable sealing function by supplying or discharging air appropriately according to the traveling speed of the vehicle and the pressure in the weather strip, and at the same time, the deformation of the weather strip is prevented and the door is opened and closed. You can improve the castle.
