상기 충격감지레버(2)의 수평부분의 위쪽에는 상기 중간레버(3)가 핀을 매개로 회동가능하게 설치되며, 이 중간레버(3)의 수직부분 하단은 상기 충격감지레버(2)의 걸림턱쪽으로 절곡성형되어 충격감지레버(2)의 걸림턱이 걸려지는 걸림턱이 형성되고, 중간레버(3) 수직부분의 중간부는 차체에 고정된 브라켓(4)과 수축스프링(5)으로 연결되며, 중간레버(3)의 수평부분 단부에는 걸림턱이 형성된다.The middle lever 3 is rotatably installed on the upper portion of the horizontal portion of the impact detection lever 2 via a pin, and the lower portion of the vertical portion of the intermediate lever 3 is caught by the impact detection lever 2. It is formed by bending toward the chin to form a locking jaw to catch the locking jaw of the impact detection lever (2), the middle portion of the vertical portion of the intermediate lever (3) is connected to the bracket (4) and the contracting spring (5) fixed to the vehicle body , The locking jaw is formed at the end of the horizontal portion of the intermediate lever (3).
한편, 후드(6)의 개구부 뒤쪽 아랫면에는 마운팅브라켓(7)이 장착되고, 이 마운팅브라켓(7)의 상부 전방에 에어가이드(8)의 후단이 핀을 매개로 힌지고정되며, 이 에어가이드(8)의 아랫면에는 하방으로 연장되다가 전방으로 절곡연장된 고정레버(9)가 고정설치되며, 이 고정레버(9)의 수평부분 단부에도 걸림턱이 형성되어 상기 중간레버(3)의 상단 걸림턱에 걸려진다.On the other hand, a mounting bracket 7 is mounted on the lower rear side of the rear of the hood 6, and the rear end of the air guide 8 is hinged and fixed to the upper front of the mounting bracket 7 via a pin. The lower surface of 8) is fixed to the fixing lever 9 extending downward and bent forward and fixed, the locking jaw is formed in the horizontal end of the fixing lever 9, the upper locking jaw of the intermediate lever (3) Is caught in.
또한, 상기 고정레버(9)의 수직부분은 상기 마운팅브라켓(7)의 하부와 제 2수축스프링(10)으로 연결되어 있다.In addition, the vertical portion of the fixing lever 9 is connected to the lower portion of the mounting bracket 7 and the second shrinkage spring 10.
상기와 같은 정상상태에서 에어가이드(8)는 앞쪽 단부가 위로 들어 올려진상태로서 개구된 앞부분을 통하여 인터쿨러로 공기가 원활히 유입될 수 있다.In the normal state as described above, the air guide 8 may be smoothly introduced into the intercooler through the opened front portion as the front end is lifted up.
이제 도 3을 참조하여 본 발명의 작동과정을 설명한다.Referring now to Figure 3 will be described the operation of the present invention.
차량이 주행중 보행자를 치게 되면, 범퍼에 충격이 가해지므로 범퍼커버(1)가 뒤로 밀리게 되며, 이에 의해 범퍼커버(1)의 내면에 상부가 접촉된 충격감지레버(2)가 반시계방향으로 회전되어 이의 걸림턱과 중간레버(3) 걸림턱의 걸림상태가 풀어져 중간레버(3)의 구속상태가 해제되며, 구속해제된 중간레버(3)는 제 1수축스프링(5)에 의해 당겨져 역시 반시계방향으로 회전된다.When the vehicle hits a pedestrian while driving, the bumper cover 1 is pushed back because an impact is applied to the bumper, whereby the impact detection lever 2 having an upper contact with the inner surface of the bumper cover 1 is counterclockwise. The locking state of the locking jaw and the middle lever (3) of the locking jaw is released to release the restraint state of the intermediate lever (3), and the restrained intermediate lever (3) is pulled by the first shrink spring (5). Rotate counterclockwise.
중간레버(3)가 반시계방향으로 회전됨으로써 중간레버(3)의 걸림턱과 상기 고정레버(9)의 걸림턱의 걸림상태가 해제되어 고정레버(9)는 회동이 자유로운 상태가 되며, 이때 마운팅브라켓(7)에 설치된 제 2수축스프링(10)에 의해 당겨져 시계반대방향으로 회전되므로 이 고정레버(9)가 장착되어 있는 에어가이드(8)도 동일한 방향으로 회전되어 후드(6)의 내부로 인입되어져 에어가이드(8)의 상면은 후드(6)와 동일한 면을 이루게 된다.When the intermediate lever 3 is rotated counterclockwise, the locking state of the locking jaw of the intermediate lever 3 and the locking jaw of the fixing lever 9 is released, and the fixing lever 9 is free to rotate. Since it is pulled by the second shrinkage spring 10 installed in the mounting bracket 7 and rotated counterclockwise, the air guide 8 on which the fixing lever 9 is mounted is also rotated in the same direction, so that the inside of the hood 6 is rotated. It is drawn into the upper surface of the air guide 8 is to form the same surface as the hood (6).
즉, 보행자와 충돌사고 발생시 범퍼에 충격이 전해지면 이와 동시에 에어가이드(8)가 하방으로 숙여져 후드(6)와 동일면을 이루게 되므로, 충돌직후 후드의 상면으로 보행자의 신체가 이동하여도 재차 충돌하는 부분이 없어지게 되므로 에어가이드(8)에 의한 보행자의 2차상해가 방지되도록 된 것이다.That is, when an impact is transmitted to the bumper when a collision accident occurs with the pedestrian, the air guide 8 is leaned downward to form the same plane as the hood 6, so that the collision occurs again even if the body of the pedestrian moves to the upper surface of the hood immediately after the collision. Since the part to be disappeared is to prevent secondary injury of the pedestrian by the air guide (8).
한편, 엔진룸의 정비점검을 위해 후드(6)를 들어올리면 안전레버(3)의 걸림턱은 충격감지레버(2)의 걸림턱을 미끄러지면서 타고 넘을 수 있도록 두 걸림턱은 둥글게 형성되어 있으며, 후드(6)가 닫힐때도 다시 부드럽게 결속될 수 있도록 되어 있어 에어가이드 작동장치의 설치에도 불구하고 후드(6)의 개폐동작은 자연스럽게 이루어질 수 있도록 되어 있음은 물론이다.Meanwhile, when the hood 6 is lifted for maintenance of the engine room, the locking jaws of the safety lever 3 are rounded so that the locking jaws slide over the locking jaws of the impact detection lever 2 so that they can ride over. Even when the hood 6 is closed, it is possible to smoothly bind again, so that the opening and closing operation of the hood 6 is naturally made despite the installation of the air guide actuator.
이상 설명한 바와 같이 본 발명에 따르면, 차량이 보행자를 치었을 때 범퍼에 전해지는 충격으로 작동되어 에어가이드가 후드의 내부로 인입됨으로써 충돌직후 보행자의 신체가 후드의 상면을 타고 이동할 때 걸려지는 부분이 없게 되어 보행자의 2차상해를 방지할 수 있게 되는 효과가 있다.As described above, according to the present invention, the vehicle is operated by the impact transmitted to the bumper when the vehicle hits the pedestrian, so that the air guide is introduced into the hood, so that the part caught by the pedestrian's body immediately after the collision moves on the upper surface of the hood. There is an effect that can prevent the secondary injury of the pedestrians.
