A weather strip for a hood of an automobile which can be prevented from being made.

일반적으로, 자동차의 엔진룸에는 외부 이물질 및 충격등으로부터 엔진 및 각종 부품들을 보호하기 위하여 후드가 설치되어 있고, 엔진룸의 전면은 공기 순환을 위해 라디에이터 그릴이 설치되어 있게 된다.In general, a hood is installed in the engine room of a vehicle to protect the engine and various parts from external debris and impact, and the front of the engine room is provided with a radiator grill for air circulation.

상기한 엔진룸의 후드는 엔진등의 유지 보수를 위해 개폐 가능하게 설치되어 있고, 엔진룸 내부의 각 부품을 보호함과 아울러 엔진룸 내부로 이물질등이 많이 들어가지 않도록 웨더스트립이 설치되어 있게 된다.The hood of the engine room is installed to open and close for maintenance of the engine, and a weather strip is installed to protect each part inside the engine room and to prevent foreign substances from entering the engine room. .

즉, 후드와 엔진룸의 사이로 이물질이 많이 들어가지 않도록 함과 아울러 후드로 엔진룸을 보호하게 되는 것이다.That is, the foreign matter does not enter between the hood and the engine room, and the engine room is protected by the hood.

상기한 웨더 스트립은 도3에 도시된 바와 같이 후드(H)의 인너 판넬(I)에 클립(50)으로 고정부(51)가 결합됨과 아울러 엔진룸을 이루는 라디에이터 써포트멤버(R)에 밀착되도록 탄성부(52)가 연장 형성되어 있다.As shown in FIG. 3, the weather strip is coupled to the inner panel I of the hood H by the clip 50 to the fixing part 51 and closely adhered to the radiator support member R forming the engine room. The elastic part 52 is extended.

여기서, 상기한 후드(H)의 선단에는 웨더스트립과 밀착된 라디에이터 써포트멤버(R)를 덮고, 라디에이터 그릴(G)과 후드(H)의 형상을 유선형등으로 일치시키기 위해 전면부(53)가 돌출 형성되어 있다.Here, the front end 53 covers the radiator support member R in close contact with the weather strip at the tip of the hood H, and the front part 53 is adapted to match the shape of the radiator grill G and the hood H in a streamlined manner. It is formed to protrude.

즉, 상기한 웨더스트립과 라디에이터 써포트멤버(R)가 서로 밀착되어 엔진룸 내부를 외부와 차폐시키는 상태에서, 후드(H)의 전면부(53)가 그 앞부분을 커버하면서 웨더스트립을 보호하고 라디에이터 그릴(G)과 후드(H)의 형상을 일치시키도록 하는 것이다.That is, while the weather strip and the radiator support member R are in close contact with each other to shield the inside of the engine room from the outside, the front part 53 of the hood H covers the front part while protecting the weather strip and radiator The shape of the grille G and the hood H are made to match.

즉, 상기한 웨더스트립을 후드(H)의 저면에 고정시키게 되면 전면 및 후면차단부(2-1, 2-2)가 후드(H)와 라디에이터 써포트멤버(R)와의 사이 공간(라디에이터 그릴의 윗부분)을 차폐하여 고속 주행 시 바람이 들어가지 않도록 하고, 라디에이터 써포트멤버(R)와는 탄성부(3)가 밀착되어 엔진룸 내부를 외부와 차폐하게 되는 것이다.That is, when the weather strip is fixed to the bottom surface of the hood H, the front and rear blocking portions 2-1 and 2-2 are spaces between the hood H and the radiator support member R (of the radiator grille). Upper part) to shield the wind from entering at high speed, and the radiator support member (R) is in close contact with the elastic portion (3) to shield the inside of the engine room from the outside.

특히, 상기한 전면 및 후면차단부(2-1, 2-2)에는 웨더스트립을 후드(H)에 클립(1)으로 고정시킬 때, 후드(H)의 내측면에 부착되는 실러와의 간섭을 방지하도록 곡면부(4)가 형성되어 있다.In particular, when the weather strip is fixed to the hood H by the clip 1 on the front and rear blocking portions 2-1 and 2-2, the interference with the sealer attached to the inner side of the hood H is fixed. The curved surface portion 4 is formed to prevent this.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 작업자가 웨더스트립을 후드(H)의 저면에 클립(1)으로 고정시키게 되면, 후드(H)의 선단으로는 후면차단부(2-2)가 위치되고, 그 후면으로는 탄성부(3)가 위치된 상태가 된다.Referring to the operation and effect of the present invention as described above, if the worker to fix the weather strip to the bottom of the hood (H) with the clip (1), the rear blocking portion (2-2) to the front end of the hood (H) Position, and the elastic part 3 is located in the back surface.

이 상태에서 후드(H)를 닫게 되면 탄성부(3)는 라디에이터 써포트멤버(R)에 밀착되어 있게 되고, 전면 및 후면차단부(2-1, 2-2)는 후드(H)와 라디에이터 써포트멤버(R)의 사이 공간을 차폐하게 되는 바, 상기한 상태에서 차량이 주행을 하게 되면 차량 전면부인 라디에이터 그릴에 고속의 공기가 충돌하게 된다.In this state, when the hood (H) is closed, the elastic portion (3) is in close contact with the radiator support member (R), and the front and rear blocking portions (2-1, 2-2) are the hood (H) and the radiator support Since the space between the members R is shielded, when the vehicle runs in the above state, high-speed air collides with the radiator grille, which is the front part of the vehicle.

고속의 공기가 차량 전면부인 라디에이터 그릴로 충돌하게 되면 라디에이터 그릴을 타고 흐르면서 후드(H)로 흐르게 되는 바, 이때 상기한 공기는 웨더스트립의 전면 및 후면차단부(2-1, 2-2)에 의해 차단되면서 후드(H)와 라디에이터 써포트멤버(R)의 사이로 들어가지 못하고 후드(H)의 외부를 타고 흐르게 된다.When high-speed air collides with the radiator grille, which is the front part of the vehicle, the high-speed air flows through the radiator grille and flows into the hood H. At this time, the air flows to the front and rear cutoff portions 2-1 and 2-2 of the weather strip. As it is blocked by the hood (H) and the radiator support member (R) does not enter between flowing through the hood (H) outside.

즉, 전면차단부(2-1)가 후드(H)의 끝부분과 라디에이터 써포트멤버(R)의 사이를 차폐하고 있기 때문에 고속의 공기가 이를 통해 엔진룸으로 유입되지 못하고 후드(H)를 타고 외부로 흐르게 되는 것이다.That is, since the front cut-off part 2-1 shields between the end of the hood H and the radiator support member R, high-speed air does not flow into the engine room through the hood H. It will flow outside.

고속의 공기가 후드(H)와 라디에이터 써포트멤버(R)의 사이로 유입되지 않게 되면, 종래와 같은 고주파음인 휘슬소음이 발생되지 않게 된다.When high-speed air does not flow between the hood H and the radiator support member R, whistle noise, which is a high frequency sound as in the prior art, is not generated.

또한, 상기한 후드(H)를 개폐시킬 때 운전자가 후드(H)의 끝부분을 잡고 후드(H)를 들어올리거나 내리게 되는 바, 상기한 후드(H)의 끝부분 저면에 전면 및 후면차단부(2-1, 2-2)가 있기 때문에, 후드(H)를 내릴 때 라디에이터 써포트멤버(R)와의 사이에 손이 끼어도 다치지 않게 된다.In addition, when opening and closing the hood (H), the driver grasps the end of the hood (H) to lift or lower the hood (H), the front and rear blocking portion on the bottom of the end of the hood (H) Since there are (2-1, 2-2), when the hood H is lowered, a hand is caught between the radiator support member R so as not to be injured.

즉, 부드러운 재질인 웨더스트립의 전면 및 후면차단부(2-1, 2-2)에 손이 눌려도 다치지 않게 됨으로써 무거운 후드(H)를 내려서 닫을 때에 운전자가 손에 부상을 입지 않게 되는 것이다.That is, the driver is not injured when the heavy hood (H) is lowered and closed by being injured even when hands are pressed against the front and rear blocking portions (2-1, 2-2) of the weather strip, which is a soft material. .

이상과 같이 본 발명은 전면 및 후면차단부가 후드와 라디에이터 써포트멤버의 사이로 고속의 공기가 유입되지 않도록 하고 탄성부가 후드와 라디에이터 써포트멤버를 지지하게 됨으로써, 차량의 고속 주행 중 후드와 라디에이터 써포트멤버와의 사이에서 발생되는 고주파 휘슬음을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention prevents the high-speed air from flowing between the hood and the radiator support member, and the elastic part supports the hood and the radiator support member, so that the hood and the radiator support member are fast-dried during the high speed driving of the vehicle. There is an advantage that can prevent the high frequency whistle generated between.
