본 발명은 차량도어에 적용된 웨더스트립 구조에 관한 것으로서, 보다 상세하게는 차량이 정차중인 상태에서는 웨더스트립의 내부를 진공시키지 않고, 차량이 주행중인 상태에서는 그 주행속도에 따라 웨더스트립 내부의 진공압력을 변화시키면서 도어패널과 웨더스트립의 접촉력을 증가시켜 차량도어 부위에서 발생되는 윈드 노이즈(wind noise)를 방지할 수 있도록 하는 윈드 노이즈 저감을 위한 도어 웨더스트립 구조에 관한 것이다.The present invention relates to a weather strip structure applied to a vehicle door, and more particularly, does not vacuum the inside of the weather strip when the vehicle is stopped, and the vacuum pressure inside the weather strip according to the traveling speed when the vehicle is running. The present invention relates to a door weather strip structure for reducing wind noise by increasing the contact force between the door panel and the weather strip while preventing the wind noise generated in the vehicle door area.

주지된 바와같이, 차량의 성능이 계속적으로 향상되면서 출력증대를 통한 치고속도 또한 높이지고 있는 추세이다.As is well known, as the performance of the vehicle continues to improve, the high speed through the increase in power is also increasing.

또한 좀더 정숙성과 안락함을 원하는 운전자나 승객들의 요구에 부응하기 위해 각종 노이즈를 최대한 줄여 나가는 것이 차량 개발자들의 입장이다.It is also the position of the vehicle developer to reduce noise as much as possible to meet the needs of drivers and passengers who want more quietness and comfort.

각종 동력계통의 소음이나 부대장치의 소음은 개별적인 연구를 통해 소음 저감 효과가 많이 이루어지고 있으나, 차량 실주행에서 발생되는 차량 형상에 의해 발생되는 윈드 노이즈는 그 저감을 위해 상당한 연구 및 투자가 필요로 하였으며, 이를 위해 차량 디자인의 변경이나 각종 돌출물의 형상을 유선형으로 변형하여 외부 공기의 흐름을 제어하게 되었다.Although the noise of various power systems and the noise of auxiliary devices have been greatly reduced through individual studies, the wind noise generated by the shape of the vehicle generated in the running of the vehicle requires considerable research and investment. For this purpose, the flow of outside air was controlled by changing the design of the vehicle or by deforming the shape of various protrusions in a streamlined manner.

이에 종래에는 도어의 윈드 노이즈 발생을 방지하도록 도어의 각 모서리 부위나 떨리는 부위에 위치하는 웨더 스트립 내부에 코어(core) 또는 심(shim)을 넣어 두었다.In the prior art, a core or shim was placed in a weather strip located at each corner of the door or at a trembling portion to prevent wind noise of the door.

그러나, 종래에는 웨더스트립내에 삽입되는 코어 또는 심에 의해 도어의 닫힘이 제대로 이루어지지 않게 되었으며, 만약 코어 또는 심을 제거할 경우에는 차량이 정차된 상태에서 도어의 밀착성이 우수하지만, 도 1에서와 같이 차량이 주행중일 경우에는 윈드 노이즈(도 1의 A부분)가 심하게 발생되는 문제점을 초래하게 되었다.However, in the related art, the door is not closed properly by the core or the shim inserted into the weather strip. If the core or the shim is removed, the door is excellent in the stopped state of the vehicle, as shown in FIG. When the vehicle is running, the wind noise (part A of FIG. 1) is badly caused.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서 본 발명의 목적은, 차량의 주행상태에 따라 도어 웨더스트립내의 진공압력을 조절하도록 구성함으로써, 차량이 정차시에는 웨더스트립의 내부를 진공시키지 않고, 차량이 주행중인 상태에서는 그 주행속도에 따라 웨더스트립 내부의 진공압력을 변화시키면서 도어패널과 웨더스트립의 접촉력을 증가시켜 차량도어 부위에서 발생되는 윈드 노이즈를 방지하면서 운전자는 물론 승객들에게 차량 탑승시의 정숙성과 안락함을 함께 제공할 수 있도록 하는 윈드 노이즈 저감을 위한 도어 웨더스트립 구조를 제공하려는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems as described above, and an object of the present invention is to adjust the vacuum pressure in the door weather strip according to the driving condition of the vehicle, thereby to prevent the interior of the weather strip when the vehicle is stopped. Instead of vacuuming, while the vehicle is running, the contact pressure between the door panel and the weather strip is increased while changing the vacuum pressure inside the weather strip according to the driving speed, thereby preventing wind noise generated in the area of the vehicle door. It is intended to provide a door weather strip structure for wind noise reduction, which can provide the quietness and comfort in the vehicle.

이하, 첨부된 도면에 의거하여 본 발명의 바람직한 일실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명의 일실시예로 차량 구조도이고, 도 3은 본 발명의 일실시예로 도 2의 B부분 확대단면도이며, 도 4는 본 발명의 일실시예로 도어패널과 웨더스트립의 밀착상태를 보인 개략도 이다.2 is a structural view of a vehicle according to an embodiment of the present invention, FIG. 3 is an enlarged cross-sectional view of a portion B of FIG. 2 as an embodiment of the present invention, and FIG. 4 is a close contact between a door panel and a weather strip as an embodiment of the present invention. It is a schematic diagram showing the condition.

도 2 내지 도 4에 도시된 바와같이, 차량 도어(1)에 웨더스트립(2)이 적용되는 구조에 있어서,2 to 4, in the structure in which the weather strip 2 is applied to the vehicle door 1,

상기 웨더스트립(2)의 내부는 진공압력이 유지되는 공간부(10)를 형성하고, 상기 웨더스트립(2)의 일면에는 공간부(10)의 진공압력에 따라 도어(1)를 끌어당기 면서 도어(1)와 차체의 밀착력을 증대시키는 다수개의 압착구멍(20)을 형성하며, 상기 공간부(10)에 대한 진공압력은 차량주행시 진공압력조절밸브(30)의 온/오프를 통해 조절되도록 구성하고, 상기 진공압력조절밸브(30)의 온/오프는 차량도어의 자동개폐를 위한 도어스위치(40)에 의해 온/오프되도록 구성함을 특징으로 한다.The inside of the weather strip 2 forms a space portion 10 in which vacuum pressure is maintained, and on one surface of the weather strip 2 draws the door 1 in accordance with the vacuum pressure of the space portion 10. A plurality of pressing holes 20 are formed to increase the adhesion between the door 1 and the vehicle body, and the vacuum pressure for the space 10 is controlled by turning on / off the vacuum pressure control valve 30 when the vehicle is driven. And, the on / off of the vacuum pressure control valve 30 is characterized in that configured to be turned on / off by the door switch 40 for automatic opening and closing of the vehicle door.

이와같이 구성된 본 발명의 일실시예에 대한 작용을 첨부된 도 2 내지 도 4를 참조하여 설명하면 다음과 같다.Referring to Figures 2 to 4 attached to the operation of an embodiment of the present invention configured as described above are as follows.

먼저, 차량이 정차중인 상태에서 도어스위치(40)의 오프로부터 차량도어(1)가 열리는 경우, 진공압력조절밸브(30)는 오프되면서 웨더스트립(2)내의 공간부(10)는 진공상태가 해제된다.First, when the vehicle door 1 is opened from the off of the door switch 40 while the vehicle is stopped, the vacuum pressure regulating valve 30 is turned off while the space 10 in the weather strip 2 is in a vacuum state. Is released.

그러나, 차량도어(1)를 닫은 상태에서 차량을 주행시킨 후 도어스위치(40)를 온 시키면, 진공압력조절밸브(30)는 온 되면서 웨더스트립(2)내의 공간부(10)를 진공상태로 유지시킨다.However, if the door switch 40 is turned on after driving the vehicle in the state in which the vehicle door 1 is closed, the vacuum pressure control valve 30 is turned on and the space 10 in the weather strip 2 is turned into a vacuum state. Keep it.

이때, 상기 공간부(10)내의 진공압력은 차량의 주행속도가 높을수록 커지고, 주행속도가 낮으면 그 진공압력은 낮아지도록 하였다.At this time, the vacuum pressure in the space 10 is increased as the running speed of the vehicle increases, and when the running speed is low, the vacuum pressure is lowered.

따라서, 상기 공간부(10)의 진공상태로부터 웨더스트립(2)의 일면에 다수개 형성된 압착구멍(20)은 도어(1)를 끌어당기면서 도어(1)와 차체의 밀착력을 증대시키게 되는 바, 차량이 지속이나 고속으로 주행할 때 차량도어(1)와 차체의 뜸새를 통해 발생되는 윈드 노이즈를 보다 효과적으로 저감시킬 수 있게 되는 것이다.Therefore, the plurality of pressing holes 20 formed on one surface of the weather strip 2 from the vacuum of the space 10 increase the adhesion between the door 1 and the vehicle body while pulling the door 1. When the vehicle continues to run at high speed, the wind noise generated through the moss of the vehicle door 1 and the vehicle body can be more effectively reduced.

이상에서 설명한 바와같이 본 발명은 차량의 주행상태에 따라 도어 웨더스트 립내의 진공압력을 조절하도록 구성함으로써, 차량이 정차시에는 웨더스트립의 내부를 진공시키지 않고, 차량이 주행중인 상태에서는 그 주행속도에 따라 웨더스트립 내부의 진공압력을 변화시키면서 도어패널과 웨더스트립의 접촉력을 증가시켜 차량도어 부위에서 발생되는 윈드 노이즈를 방지하면서 운전자는 물론 승객들에게 차량 탑승시의 정숙성과 안락함을 함께 제공하는 특징을 갖는다.As described above, the present invention is configured to adjust the vacuum pressure in the door weather strip according to the running state of the vehicle, so that the traveling speed is not increased while the vehicle is running, without vacuuming the inside of the weather strip when the vehicle is stopped. By changing the vacuum pressure inside the weather strip while increasing the contact force between the door panel and the weather strip to prevent wind noise generated in the vehicle door area while providing quietness and comfort to the driver and passengers while riding the vehicle.
