Description

차량용 도어의 기밀구조{The airtight structure in vehicle}The airtight structure in vehicle

본 발명은 차량용 도어의 기밀구조에 관한 것으로, 보다 상세하게는 도어와의 밀착력을 높여 완전한 기밀을 유지 할 수 있도록 된 차량용 도어의 기밀구조에 관한 것이다.The present invention relates to a gas tight structure of a door for a vehicle, and more particularly to a gas tight structure of a vehicle door that can maintain a complete air tightness by increasing the adhesion to the door.

일반적으로 승객이 탑승 및 내리는 도어나 엔진후드와 트렁크리드등과 같이 지속적으로 개폐되는 차량의 부위에는 통상, 닫힌 상태에서 외부로부터 물과 같은 액체나 주행 중 스치는 바람등이 차량 실내로 유입되지 못하도록 기밀을 유지하게 되는데 이중, 도 1에 도시된 바와 같이 도어(D)와 차량의 지붕을 이루는 루프(R)사이에는 이와 같은 기밀을 유지하기 위해 웨더스트립(1)을 사용하게 된다.In general, the part of a vehicle that is continuously opened and closed such as a door that a passenger boards and gets off or an engine hood or a trunk lid is normally closed to prevent liquid such as water from the outside or wind that is passing during driving. Of these, as shown in FIG. 1, the weather strip 1 is used to maintain such airtightness between the door D and the roof R that forms the roof of the vehicle.

이와 같은 웨더스트립(1)은 도 2에 도시된 바와 같이, 차체의 루프(R)패널의 형상을 따라 끼워지면서 일 측으로 중공을 이루어 닫히는 도어(D)에 의한 가압 시 A방향으로 변형되면서 기밀을 유지하는 기밀부(1a)가 형성되어진다.As shown in FIG. 2, the weather strip 1 is deformed in the A direction when pressurized by the door D, which is fitted along the shape of the roof R panel of the vehicle body and is hollowed to one side and closed. An airtight portion 1a to be retained is formed.

그러나, 이와 같은 웨더스트립(1)은 닫히는 도어(D)에 의해 가압되면서 변형될 때 기밀부(1a)가 변형되면서 차량의 실내 쪽으로 돌출되므로 미관을 저해함은 물론, 차체에 장착되는 도어(D)와 루프(R)패널사이에서 발생되는 조립공차에 의해 기밀성이 저하되는 고질적인 문제가 있게 된다.However, when the weather strip 1 is deformed while being pressed by the closing door D, the airtight part 1a is deformed and protrudes toward the interior of the vehicle, thereby inhibiting aesthetics, as well as the door D mounted on the vehicle body. ), There is a chronic problem that the airtightness is lowered due to the assembly tolerance generated between the panel and the roof (R) panel.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 웨더스트립의 변형을 가하지 않으면서 도어로 접근하려는 자력을 이용하여 도어와 차체 사이의 기밀을 유지해 기밀성을 향상함과 더불어 외관미도 향상함에 그 목적이 있다.Therefore, the present invention was invented in view of the above-described problems, and by maintaining the airtightness between the door and the vehicle body by using magnetic force to access the door without applying the deformation of the weather strip, the airtightness is improved and the appearance is also improved. There is a purpose.

상기와 같은 목적을 달성하기 위한 본 발명은, 차량의 루프패널 형상을 따라 끼워져 닫힌 도어에 접촉되면서 기밀을 유지하는 웨더스트립과, 상기 도어측 방향을 향하도록 웨더스트립에 형성되면서 자력을 매개로 닫힌 도어쪽으로 이동되는 기밀부로 이루어지되,상기 기밀부는 그 내부가 빈 자바라형상으로 중첩되게 이어진 이완부와, 이 이완부의 일단에서 도어와의 접촉면적을 최대로 하도록 도어의 형상을 따라 이루어진 밀착단 및 이 밀착단내에 수용되어 닫힌 도어쪽으로 이완부가 늘어나 도어에 밀착되면서 기밀을 유지하도록 자력을 갖는 영구자석으로 구성된 것을 특징으로 한다.The present invention for achieving the above object, the weather strip is inserted along the shape of the roof panel of the vehicle to contact the closed door to maintain airtightness, while being formed on the weather strip to face the door side direction closed through the magnetic force The airtight portion is composed of an airtight portion which is moved toward the door, wherein the airtight portion has a loosening portion which is overlapped in an empty bellows shape, and an adhered end formed along the shape of the door to maximize the contact area with the door at one end of the loosening portion, and It is characterized in that it consists of a permanent magnet having a magnetic force to be kept in close contact with the door is extended in the close to the closed door is closed in close contact with the door.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 차량용 도어와 루프부위의 기밀 구성 단면도를 도시한 것인바, 본 발명은 도어(D)와 차량의 지붕을 이루는 루프(R)사이에 구비된 웨더스트립(1)이 루프(R)패널의 형상을 따라 끼워지면서 일 측으로 도어(D)와 접촉되어 기밀을 유지하는 기밀부(1a)가 형성되되, 이 기밀부(1a)는 그 내부가 빈 자바라(Jabara)형상으로 중첩되게 이어진 이완부(1c)와, 이 이완부(1c)의 일단에 도어(D)와 자력을 매개로 접촉되어 기밀을 유지하도록 그 내부에 영구자석(1b')이 내장된 밀착단(1b)이 형성되어진다.Figure 3 is a cross-sectional view showing the airtight configuration of the vehicle door and the roof portion according to the present invention, the present invention is a weather strip (1) provided between the roof (R) forming the roof of the door (D) roof (R) the airtight portion 1a is formed while being fitted along the shape of the panel and in contact with the door D on one side to maintain airtightness, and the airtight portion 1a overlaps the shape of a hollow Jabara inside thereof. The loose end part 1c which continued, and the close end 1b in which the permanent magnet 1b 'is built in the inside of it in contact with the door D and the magnetic force at the one end of this loose part 1c are maintained in airtightness. Is formed.

여기서, 상기 밀착단(1b)은 도어(D)와의 접촉면적을 최대로 하도록 도어(D)의 형상을 따라 평평하게 이루어짐은 물론이다.Here, the close end (1b) is of course made flat along the shape of the door (D) to maximize the contact area with the door (D).

이에 따라, 도어(D)를 열게 되면 도 5에 도시된 바와 같이, 도어(D)와 영구자석(1b')의 자력을 매개로 서로 밀착되었던 웨더스트립(1)의 밀착단(1b)의 접촉면(K)이 떨어지게 되고 이때, 상기 밀착단(1b)은 통상적으로 웨더스트립(1)의 재질 특성인 자체의 탄성에 의해 이완부(1c)를 수축시키게 된다.Accordingly, when the door D is opened, as shown in FIG. 5, the contact surface of the close end 1b of the weather strip 1 which is in close contact with each other by the magnetic force of the door D and the permanent magnet 1b '. (K) is to fall off, at this time, the close end (1b) is to shrink the loosening portion (1c) by the elasticity of the material characteristic of the weather strip (1).

한편, 도어(D)를 닫게 되면 도 4에 도시된 바와 같이, 닫힌 도어(D)가 루프(R)패널에 끼워진 웨더스트립(1)의 밀착단(1b)에 위치되어지는데 이때, 상기 밀착단(1b)의 영구자석(1b')의 자력에 의해 밀착단(1b)이 도어(D)에 붙으려는 힘이 발생되면서 이완부(1c)를 인장시키게 되고, 이에 따라, 상기 웨더스트립(1)과 도어(D)와의 기밀성이 더욱 완전하게 이루어지게 됨은 물론이다.On the other hand, when the door (D) is closed, as shown in Figure 4, the closed door (D) is located at the close end (1b) of the weather strip (1) fitted to the roof (R) panel, the close end As the force of the close end 1b attaching to the door D is generated by the magnetic force of the permanent magnet 1b 'of (1b), the loosening part 1c is tensioned, and accordingly, the weather strip 1 Of course, the airtightness with the door (D) is more complete.

이상 설명한 바와 같이 본 발명에 의하면, 웨더스트립이 도어와 자력을 매개로 서로 밀착되면서 도어와 루프패널사이에 수축과 인장되면서 기밀성을 유지하게 되므로 가압력 작용에 의한 차량의 실내 쪽으로의 변형이 없어 미관을 저해하지 않음은 물론, 차체에 장착되는 도어와 루프패널사이에서 발생되는 조립 공차가 도어와 웨더스트립의 자력에 의해 제거되므로 불완전한 접촉에 따른 기밀성의 저하를 완전히 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the weather strip keeps airtightness as it contracts and tensions between the door and the roof panel while closely contacting each other through the door and the magnetic force, so that there is no deformation toward the interior of the vehicle due to the pressing force. As well as not impairing, assembly tolerances generated between the door and the roof panel mounted on the vehicle body are removed by the magnetic force of the door and the weather strip, thereby completely preventing a decrease in airtightness due to incomplete contact.
