본 발명은 자동차 도어의 웨더스트립 배수구조에 관한 것으로, 특히 웨더스트립의 변형에 영향 받지 않고 양호한 배수성능을 확보할 수 있도록 된 자동차 도어의 웨더스트립 배수구조에 관한 것이다.The present invention relates to a weather strip drainage structure of an automobile door, and more particularly, to a weather strip drainage structure of an automobile door capable of ensuring a good drainage performance without being affected by deformation of the weather strip.

일반적으로 차체의 측부에는 실내로의 출입과 주행시 실내공간을 외부와 격리하여 탑승자를 보호하기 위한 도어가 구비된다.In general, the side of the vehicle body is provided with a door to protect the occupant to isolate the interior space from the outside during entry and exit into the interior.

그런데, 차체와 도어의 사이에 간극이 존재하게 되므로 이 간극을 통해 외부로부터 소음, 수분, 오염물질 등이 침투하는 것을 방지하고, 도어를 닫을 때 충격음이 발생하는 것을 방지하며, 또한 주행중 윈드노이즈가 발생하는 것을 방지하기 위하여 도 1에 도시된 바와 같이 도어(1)와 차체 사이드부(2)의 사이에는 웨더스트립(3,4)을 개재하고 있다.However, a gap exists between the vehicle body and the door, thereby preventing noise, moisture, and contaminants from penetrating from the outside through the gap, and preventing the occurrence of impact noise when the door is closed. In order to prevent this from happening, weather strips 3 and 4 are interposed between the door 1 and the vehicle body side portion 2 as shown in FIG.

그런데, 세차시 분출수의 고압에 의하여 상기 웨더스트립(3,4) 사이의 공간(S)으로 침투된 수분은 도어를 열지 않는 경우 세차가 끝난 후에도 배수되지 않게 되어 결국 위쪽의 웨더스트립(3)을 통해 실내로 유입되는 경우가 발생한다.However, the water penetrated into the space (S) between the weather strips (3,4) by the high pressure of the spouting water at the time of washing is not drained even after the end of the car wash when the door is not opened, eventually the upper weather strip (3) Inflow into the room occurs.

또한, 세차중에는 분출수의 압력이 지속적으로 작용하므로 더욱 용이하게 실내로 침투되어 바닥면을 오염시키는 문제점이 있었다.In addition, during car wash, the pressure of the jet water is continuously acted to penetrate into the room more easily to contaminate the floor surface.

따라서, 종래에는 도 2에 도시된 바와 같이, 아래쪽의 웨더스트립(4)에 드레인홀(4a)을 형성하여 상기 도어(1)와 차체 사이드부(2) 사이 공간(S)으로부터 외부로 수분의 배출이 용이하게 이루어지도록 하고 있었다.Accordingly, as shown in FIG. 2, a drain hole 4a is formed in the lower weather strip 4 so that water is discharged from the space S between the door 1 and the vehicle body side part 2 to the outside. Emission was made easy.

그러나, 상기 웨더스트립(4)은 도어가 닫힘으로써 도어(1)와 차체 사이드부(2) 사이에서 압축되므로 도 3에 도시된 바와 같이 드레인홀(4a)의 면적이 (a)에 서 (b)의 상태로 감소됨으로써 수분의 배출이 용이하게 이루어지지 않게 되는 문제점이 있었다.However, since the weather strip 4 is compressed between the door 1 and the vehicle body side part 2 by closing the door, the area of the drain hole 4a is shown in (a) as shown in FIG. By reducing the state of) there was a problem that the discharge of moisture is not easily made.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 도어 에 의해 웨더스트립이 변형되어도 드레인홀의 면적이 그대로 유지됨으로써 양호한 수분 배출성능을 확보할 수 있도록 된 자동차 도어의 웨더스트립 배수구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, it provides a weather strip drainage structure of the car door that can ensure a good water discharge performance by maintaining the area of the drain hole even when the weather strip is deformed by the door. Has its purpose.

상기와 같은 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

도어와 차체 사이드부 사이에 웨더스트립이 구비되고, 그 중 하측 웨더스트립의 상하부에 드레인홀이 형성된 자동차 도어의 웨더스트립 배수구조에 있어서,In the weather strip drainage structure of an automobile door, a weather strip is provided between the door and the vehicle body side part, and a drain hole is formed above and below the lower weather strip.

상기 드레인홀에 도어 닫힘시 변형되지 않는 강성을 가진 홀가이드가 삽입 고정되어, 도어 닫힘시 웨더스트립이 수축되어도 상기 드레인홀의 면적을 유지하도록 된 것을 특징으로 한다.A hole guide having rigidity that is not deformed when the door is closed is inserted into and fixed to the drain hole to maintain the area of the drain hole even when the weather strip is contracted when the door is closed.

따라서, 도어와 차체 사이드부 사이 공간의 배수가 원활히 이루어짐으로써 실내로의 수분 침투가 방지된다.Therefore, the water is smoothly drained from the space between the door and the vehicle body side part, thereby preventing the penetration of water into the room.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 4는 본 발명에 따른 웨더스트립 배수구조가 적용된 도어의 웨더스트립 설 치 상태를 도시한 도면으로서, 도어(1)의 하단과 이에 대응되는 차체 사이드부(2)의 사이에는 이들 각각에 웨더스트립(3,4)이 장착되어 상대측에 밀착됨으로써 양자 사이의 간극을 차단하고 있다.FIG. 4 is a view illustrating a weather strip installation state of a door to which a weather strip drainage structure according to the present invention is applied, and a weather strip between each of the lower ends of the door 1 and the vehicle body side portion 2 corresponding thereto. (3,4) is attached and in close contact with the opposing side to block the gap between them.

본 발명은 상기 하측의 웨더스트립(4)에 형성된 드레인홀(4a)에 홀가이드(5)가 삽입 고정된 것에 그 특징이 있다.The present invention is characterized in that the hole guide 5 is inserted into and fixed to the drain hole 4a formed in the lower weather strip 4.

상기 홀가이드(5)는 도어 닫힘시 상기 웨더스트립(4)을 변형시키는 외력에 대항하여 변형되지 않는 강성을 가지며, 단단한 플라스틱이나 녹이 슬지 않는 금속 재질로 제작되는 것이 바람직하다.The hole guide 5 has a rigidity that does not deform against an external force that deforms the weather strip 4 when the door is closed, and is preferably made of hard plastic or metal that does not rust.

상기 드레인홀(4a)은 상기 웨더스트립(4)의 상부와 하부에 각각 형성된 원형의 구멍으로서, 상/하부의 드레인홀(4a) 모두에 홀가이드(5)가 삽입 고정된다.The drain hole 4a is a circular hole formed in the upper and lower portions of the weather strip 4, and the hole guide 5 is inserted into and fixed to both the upper and lower drain holes 4a.

상기 홀가이드(5)는 도 5에 도시된 바와 같이, 상기 드레인홀(4a)과 동일한 외경을 가진 원통형의 바디(5a)의 상단에 화살촉 형태의 삽입단(5b)이 형성되고, 상기 바디(5a)의 하단에는 반경방향 외측으로 절곡된 플랜지(5c)가 형성된 구조로 이루어진다.As shown in FIG. 5, the hole guide 5 has an arrowhead-shaped insertion end 5b formed at an upper end of a cylindrical body 5a having the same outer diameter as the drain hole 4a. The lower end of 5a) has a structure in which a flange 5c bent radially outward is formed.

특히, 상기 삽입단(5b)은 선형 부재가 화살촉 형상으로 절곡된 형상으로 이루어져 있어서, 삽입단(5b)은 상기 바디(5a)의 내측 홀을 차단하지 않게 된다.In particular, the insertion end 5b has a shape in which the linear member is bent into an arrowhead shape, so that the insertion end 5b does not block the inner hole of the body 5a.

또한, 상기 삽입단(5b)의 양측부는 상기 바디(5a)의 외측으로 돌출 형성됨으로써 걸림턱(5d) 역할을 하게 된다.In addition, both sides of the insertion end (5b) is formed to protrude to the outside of the body (5a) to serve as a locking jaw (5d).

따라서, 도 4에 도시된 바와 같이, 상기 웨더스트립(4)의 드레인홀(4a)에 상기 홀가이드(5)를 삽입 고정한다.Therefore, as shown in FIG. 4, the hole guide 5 is inserted into and fixed to the drain hole 4a of the weather strip 4.

웨더스트립(4)은 고무류의 탄성재질로 이루어진 것이므로 상부의 드레인홀에는 하단의 플랜지(5c)부터 삽입하고, 하부의 드레인홀에는 상부의 삽입단(5b)부터 삽입하여 도시된 바와 같이, 웨더스트림(4)의 두께부분 상면에 상기 걸림턱(5d)이 걸리고 하면에 상기 플랜지(5c)가 걸리는 상태로 홀가이드(5)를 용이하게 설치할 수 있다.Since the weather strip 4 is made of rubber-like elastic material, it is inserted from the lower flange 5c into the upper drain hole and inserted from the upper insertion end 5b into the lower drain hole, as shown. The hole guide 5 can be easily installed in a state where the locking jaw 5d is caught on the upper surface of the thick portion of the portion 4 and the flange 5c is caught on the bottom surface of the thickened portion 5d.

상기와 같이 하측의 웨더스트립(4)의 상하부에 형성된 각 드레인홀(4a)에 홀가이드(5)가 구비됨으로써 도어가 닫혀 상기 웨더스트립(4)에 수축변형이 발생하여도 상기 홀가이드(5)가 변형되지 않고 원래의 형상을 유지하여 드레인홀(4a)이 수축되지 않고 원래의 면적을 유지할 수 있게 된다.As described above, hole guides 5 are provided in the drain holes 4a formed at the upper and lower portions of the lower weather strip 4, so that the doors are closed and shrinkage deformation occurs in the weather strip 4. ) Is not deformed and the original shape is maintained so that the drain hole 4a is not contracted and the original area can be maintained.

따라서, 도어(1)와 차체 사이드부(2)의 사이 공간(S)에 고여 있던 물이 외부로 용이하게 배출되므로 차실내로 수분이 침투하는 현상을 방지할 수 있게 된다.Therefore, water accumulated in the space S between the door 1 and the vehicle body side part 2 is easily discharged to the outside, thereby preventing the phenomenon of moisture penetrating into the vehicle interior.

이상 설명한 바와 같이 본 발명에 따르면, 웨더스트립에 형성된 드레인홀에 홀가이드를 삽입하여 도어 닫힘에 의한 웨더스트립 수축시에도 드레인홀의 면적을 유지할 수 있게 됨으로써 수분 배출 성능의 저하를 방지할 수 있게 된다.As described above, according to the present invention, the hole guide is inserted into the drain hole formed in the weather strip, thereby maintaining the area of the drain hole even when the weather strip shrinks due to the door closing, thereby preventing the deterioration of the water discharge performance.

따라서, 수분이 차실내로 침투되어 바닥을 오염시키는 현상을 방지할 수 있게 되는 효과가 있다.Therefore, there is an effect that can prevent the phenomenon that the water penetrates into the vehicle interior to contaminate the floor.
