Formed to connect to the mutual pin 18 so that the second engaging portion 11 of the operating lever 8 to the pin (18).
19는 수직로드로서, 상기 수직로드(19)는 상기 핀(18)에 수직으로 연결하여 하단을 범퍼 빔(1)에 고정된 압축 스프링(20)에 연결한 것이다.19 is a vertical rod, and the vertical rod 19 is vertically connected to the pin 18 to connect a lower end to the compression spring 20 fixed to the bumper beam 1.
21은 록커로서, 상기 록커(21)는 상기 제 3 레버(16)에 지지하여 일단은 상기 작동레버(8)의 제 1 걸림부(10)에 걸리게 하고, 타단은 상기 지지관(4)에 형성한 안내공(4')을 통하여 상기 지지바(3)의 하단에 형성한 록킹 홈(6)에 록킹토록 한 것이다.21 is a locker, the locker 21 is supported by the third lever 16 so that one end is caught by the first locking portion 10 of the actuating lever 8, and the other end is supported by the support tube 4. The locking groove 6 formed at the lower end of the support bar 3 through the formed guide hole 4 'is to be locked.
이상과 같은 본 발명은 범퍼 커버(2)에 외력이 가하여 지면 즉 차량 대 차량이 충돌하거나 차량과 보행자가 충돌을 하면 범퍼 커버(2)가 후진(충격동일방향)함에 따라 충격 감지레버(7)가 반시계방향으로 회전하여 작동레버(8)를 시계방향으로 회전시킴으로서 제 1 걸림부(10)는 록커(21)의 상단을 반시계방향으로 회전시켜 지지바(3)의 록킹을 해제함과 동시에 제 2 걸림부(11)도 핀(18)의 구속을 해제하게 되는 것이다.According to the present invention as described above, when an external force is applied to the bumper cover 2, that is, when the vehicle-to-vehicle collides or the vehicle and the pedestrian collide, the bumper cover 2 moves backward (impact in the same direction) as the impact detection lever 7. Rotates counterclockwise to rotate the operation lever 8 clockwise so that the first locking portion 10 rotates the upper end of the locker 21 counterclockwise to release the locking of the support bar 3. At the same time, the second locking portion 11 also releases the restraint of the pin 18.
상기와 같이 지지바(3)의 록킹이 해제되고 핀(18)의 구속이 해제되면 압축 스프링(14)(15)(20)이 압축되면서 레버(12)(13)가 접혀짐과 동시에 수직로드(19)가 후진하고 지지바(3)가 코일 스프링(5)을 압축하여 범퍼 커버(3)가 범퍼 빔(1) 측으로 후진하면 충격을 흡수하는 것이다.As described above, when the locking of the support bar 3 is released and the restraint of the pin 18 is released, the compression springs 14, 15, and 20 are compressed and the levers 12 and 13 are folded, and at the same time, the vertical rods. When 19 is retracted and the support bar 3 compresses the coil spring 5 so that the bumper cover 3 retreats to the bumper beam 1 side, the shock is absorbed.
상기와 같이 범퍼 커버(2)가 후진하면서 압축 스프링(14)(15)(20)에 의하여 충격을 흡수함으로서 충격흡수가 양호하게 되고 차량과 보행자가 충돌할 경우에도 보행자의 충격흡수가 양호하여 상해치를 경감할 수 있는 것이다.As the bumper cover 2 retracts as described above, the shock absorber is absorbed by the compression springs 14, 15 and 20, so that the shock absorption is good and even when the vehicle and the pedestrian collide, the shock absorption of the pedestrian is good. Chi can be reduced.
이상과 같이 본 발명은 차량과 차량이 충돌하거나 차량과 보행자가 충돌할 때 범퍼 커버가 후진하면서 스프링에 의하여 충격을 흡수함으로서 충격흡수가 양호하고, 차량과 보행자가 충돌할 경우에도 충격 흡수가 양호함으로 보행자의 상해치를 경감할 수 있는 것이다.As described above, according to the present invention, when the vehicle collides with the vehicle or the pedestrian collides with the bumper cover, the shock absorber is absorbed by the spring while the bumper cover is reversed, and the shock absorption is good even when the vehicle collides with the pedestrian. Injury of pedestrians can be reduced.
