본 발명은 자동차 뒷범퍼의 레인포스먼트(Reiforcement)에 관한 것으로, 특히 후방충돌시 보다 큰 충격력을 흡수할 수 있게 한 것이다.The present invention relates to a reinforcement (reiforcement) of the rear bumper of the vehicle, and in particular, it is possible to absorb a greater impact force in the rear collision.
일반적 레인포스먼트(REIFORCEMENT : a)는, 후방충돌시 백패널(c)에 가해진 충격력을 롱지류디널(b) 및 플로워(d)로 전달하는 동시에 흡수하는 역할을 하게되는 프레임이다. 종래의 레인포스먼트(a)는 제1도(a)에 도시된 바와같이 상부에 경사면이 형성되어 있으며 용접면(a1)(a2)에 백패널(c)과 플로워(d)에 각각 용접되게 설치된다.A general reinforcement (REIFORCEMENT: a) is a frame that serves to absorb and simultaneously transmit the impact force applied to the back panel (c) to the long support branch (b) and the floor (d) during the rear collision. The conventional reinforcement (a) has an inclined surface formed on the upper portion as shown in FIG. 1 (a) and is installed to be welded to the back panel (c) and the floor (d) on the welding surfaces (a1) and (a2), respectively. do.
그러나 종래의 레인포스먼트(a)는 충격력이 집중되는 높이 508mm보다 낮은 위치에 설치되어 있어 차량의 후방 충돌시 레인포스먼트(a)가 충격력을 롱지튜디널(c) 및 플로워(d)로 원활히 전달·흡수하지 못하기 때문에 백패널(b)가 꺽이게 될 뿐만 아니라 충격흡수력이 미약하여 탑승자의 안전에 치명적인 문제점이 있었다.However, the conventional reinforcement (a) is installed at a position lower than the height of 508mm where the impact force is concentrated, so the reinforcement (a) smoothly transmits the impact force to the long ground (c) and the floor (d) during the rear collision of the vehicle. Since the back panel (b) was not bent because it could not be transmitted or absorbed, the shock absorbing power was weak, and the safety of the occupant was fatal.
실예로 일반적인 국산 자동차에 있어서 레인포스먼트(a)의 설치 최대높이는 480mm로 설계되고 있으나, 미국 FMVSS 301조에서는 후방충돌시 펜저럼(pendulum)의 충격 포인트를 20(508mm), 16로 설정하고 있기 때문에 충격 포인트를 20로 설정한 안전도 검사에 설치높이가 480mm인 충격력을 원활히 전달·흡수하지 못하는 것으로 나타내고 있다.For example, the maximum height of the installation of the reinforcement (a) is designed to be 480 mm in general domestic cars, but in the US FMVSS 301, the impact point of the pendulum is set to 20 (508 mm) or 16 in the rear collision. Therefore, the safety test with the impact point set to 20 indicates that the impact force of 480 mm in height cannot be transmitted and absorbed smoothly.
또한 종래의 레인포스먼트(a)는 제1도에 도시된 바와같이 상면이 일직선이 급격한 검사면으로 형성되어 있기 때문에 후방충격력이 레인포스먼트(a)에서 거의 흡수되지 못하고 롱지튜디널(c) 및 플로어(d)로 전달되게 되는 문제점이 있었다.In addition, in the conventional reinforcement (a), as shown in FIG. 1, since the upper surface is formed as an inspection surface with a straight line, the rear impact force is hardly absorbed by the reinforcement (a), and thus the long ground terminal (c) And there was a problem to be delivered to the floor (d).
본 발명은 이와같은 점을 감안하여 후방에 백패널 수평지지부가 형성되고 중간은 완만한 경사부로 형성되며, 전방에는 완충 수평지지부가 형성된 레인포스먼트를 팬저럼의 충격 포인트내에 위치하게 설치하여 차량의 후방충격시 충격력이 레인포스먼트에 직접 가해지게 하므로써 레인포스먼트가 백패널이 꺽이지 않도록 지지하는 것과 동시에 충격력을 효과적으로 롱지튜디널 및 플로워에 전달 ·흡수할 수 있게 하기 위한 것이다.In view of the above, the present invention has a rear panel horizontal support part formed at the rear and a moderate inclined part formed at the rear part, and a rear reinforcement having a buffer horizontal support part formed at the front is located within the impact point of the pandum. The impact force is applied directly to the reinforcement during the impact so that the reinforcement supports the back panel not to be bent and at the same time, it can effectively transmit and absorb the impact force to the long ground and the floor.
이하 본 발명의 바람직한 실시예를 첨부도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
백퍼널(5)과 플로워(6)에 용접되게 설치된 레인포스먼트에 있어서, 후방에 백패널 수평지지부(2)가 형성되고 중간은 완만한 경사부(3)로 형성되며, 전방에는 완충 수평지지부(4)가 형성된 레인포스먼트(1)의 설치높이가 충격 포인트내에 위치하게 설치하여서 된 것이다.In the reinforcement installed to be welded to the back funnel (5) and the floor (6), the back panel horizontal support portion (2) is formed at the rear, and the middle is formed of a gentle inclined portion (3), the front of the buffer horizontal support portion ( The installation height of the reinforcement 1 in which 4) was formed is located in the impact point.
이와같이 된 본 발명의 레인포스먼트(1)는 제3도에 도시된 바와같이, 후방에 백패널(5)을 지지해 줄 수 있는 백패널 수평지지부(2)가 형성되고, 상기 백패널 수평지지부(2)에 연이어 완만한 경사부(3)가 형성되어 있으며, 경사부(3)의 전방으로 충격력을 플로워(6)와 롱지튜디널(7)로 전달·흡수하는 역할을 하는 완충 수평지지부(4)가 형성되어 있다.As shown in FIG. 3, the reinforcement 1 according to the present invention has a back panel horizontal support part 2 capable of supporting the back panel 5, and the back panel horizontal support part 2 is provided. Subsequently, a gentle inclined portion 3 is formed, and a buffered horizontal support portion 4, which serves to transmit and absorb an impact force to the floor 6 and the long ground terminal 7, in front of the inclined portion 3, is provided. Formed.
이렇게 형성된 레인포스먼트(1)의 충격 포인트내에 위치하도록 설치되게 되는데, 본원 출원인은 충격 포인트를 미국 FWVSS 301조에서 후방충돌시 팬저럼의 충격 포인트로 설정하고 있는 높이 20보다 엄밀히 21로 산정하고, 차량의 급정거시 차체 후방의 상승 및 하강되는 고려하여 레인포스먼트(1)의 자체 높이에 약 35mm 이상의 여유를 주므로써 후방충돌시 레인포스먼트(1)에 충격 포인트가 위치하도록 하였다.It is installed to be located within the impact point of the reinforcement (1) formed in this way, the applicant of the present application calculates the impact point to 21 strictly higher than the height 20 is set as the impact point of the pandemoon in the rear collision in the US FWVSS section 301, In consideration of being raised and lowered at the rear of the vehicle body during sudden stop of the vehicle, the impact point is positioned at the reinforcement 1 during rear collision by giving a margin of about 35 mm or more to the height of the reinforcement 1 itself.
제4도는 팬저럼의 충격 포인트를 21로 산정하고, 상하로 35mm이상의 여유를 갖도록 한 레인포스먼트(1)의 설치위치를 보인 단면도이다.4 is a cross-sectional view showing the installation position of the reinforcement (1) in which the impact point of the pandum is calculated to be 21 and has a margin of 35 mm or more above and below.
차량의 후방충돌로 인하여 백패널(5)에 충격력이 가해지게 되면 충격 포인트가 레인포스먼트(1)의 설치위치내에 형성되기 때문에 백패널 수평지지부(2)가 백패널(5)의 지지대 역할을 하여 충격력을 완화시키는 동시에 백패널(5)이 꺽이지 않도록 한다.When the impact force is applied to the back panel 5 due to the rear collision of the vehicle, since the impact point is formed in the installation position of the reinforcement 1, the back panel horizontal support 2 acts as a support for the back panel 5 to provide impact force. At the same time, the back panel 5 is not bent.
충격력은 백패널 수평지지부(2)에서 경사부(3)로 전달되게 되는데, 상기 경사부(3)는 충격력의 방향이 급격히 바뀌는 것을 막기 위하여 완만하게 형성되어 있다. 완충 수평지지부(4)는 경사부(3)에서 전달된 충격력을 최종적으로 완하시키고 플로워(6) 및 롱지튜디널(7)로 전달·흡수시키게 된다.The impact force is transmitted from the back panel horizontal support portion 2 to the inclined portion 3, and the inclined portion 3 is gently formed to prevent the direction of the impact force from suddenly changing. The shock absorbing horizontal support part 4 finally relaxes the impact force transmitted from the inclined part 3 and transmits and absorbs it to the floor 6 and the long ground terminal 7.
이와같이 본 발명은 후방에 백패널 수평지지부(2)가 형성되고 중간은 완만한 경사부(3)로 형성되며, 전방에는 완충 수평지지부(4)가 형성된 레인포스먼트(1)를 팬저럼의 충격 포인트내에 위치하게 설치하여 차량시 후방충돌시 충격력이 레인포스먼트(1)에 직접 가해지게 하므로써 레인포스먼트(1)가 백패널(5)이 꺽이지 않도록 지지하는 것과 동시에 충격력을 효과적으로 플로워(6) 및 롱지튜디널(7)에 전달·흡수할 수 있게 한 것이다.Thus, the present invention is the back panel horizontal support (2) is formed in the rear and the middle is formed of a gentle inclined portion (3), the front of the impact point of the reinforcement (1) with the buffer horizontal support (4) formed Since the impact force is applied directly to the reinforcement when the vehicle collides with the rear force during installation, the reinforcement 1 supports the back panel 5 so as not to be bent, and at the same time, the impact force is effectively applied to the floor 6 and It is to be able to transmit and absorb to the long ground (7).
