우선 각 도면의 구성요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다. 또한, 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략하기로 한다.First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

첨부된 도면에 의거하여 본 발명의 실시예를 상세히 설명하기로 한다.Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 차량용 에너지 업서버의 사시도를 나타낸 도면이고, 도 3은 본 발명에 따른 차량용 에너지 업서버의 평면도를 나타낸 도면이며, 도 4는 도 3의 "A-A"선부를 절개하여 나타낸 도면이다.Figure 2 is a view showing a perspective view of a vehicle energy upserver according to the present invention, Figure 3 is a plan view showing a vehicle energy upserver according to the present invention, Figure 4 is shown by cutting the "AA" of FIG. Drawing.

도 2 내지 도 4에 도시된 바와 같이, 본 발명에 의한 차량용 에너지 업서버는, 헤드램프(300)의 하측 공간에 위치되는 한 쌍의 완충프레임(110)과, 이 한 쌍의 완충프레임(110) 사이에 배치되는 업서버 폼제(120)를 포함하는 구성으로, 보행자 보호 및 저속 충돌에 효과적으로 대응할 수 있다.As shown in Figures 2 to 4, the vehicle energy upserver according to the present invention, a pair of buffer frame 110 is located in the lower space of the headlamp 300, and the pair of buffer frame 110 In the configuration including the up-server foam 120 disposed between), it is possible to effectively cope with pedestrian protection and low-speed collision.

구체적으로 완충프레임(110)은 범퍼 백빔(200)의 전방 양측부에 고정 설치된 한 쌍으로 구성되되, 바람직하게 헤드램프(300)의 하측 공간에 위치된다. Specifically, the buffer frame 110 is composed of a pair fixedly installed on both front sides of the bumper back beam 200, preferably located in the lower space of the head lamp 300.

이는 근래 헤드램프(300)의 경우 해당 크기가 증대되면서 전방으로 돌출되는 추세인 점을 고려한 것으로, 변형을 통해 충돌에너지를 효과적으로 흡수할 수 있는 완충프레임(110)을 헤드램프(300)의 하측 공간에 설치함으로써, 헤드램프(300)의 돌출 구조로 인해 부족해진 에너지 흡수 공간으로부터 보행자의 다리하부를 안정적으로 보호할 수 있다.This is in consideration of the recent trend that the headlamp 300 is protruding forward as its size is increased, the buffer frame 110 that can effectively absorb the collision energy through the deformation of the lower space of the headlamp 300 By installing it in, it is possible to stably protect the lower part of the leg of the pedestrian from the energy absorption space that is insufficient due to the projecting structure of the headlamp 300.

이 완충프레임(110)은 스틸 재질로 구성되는 것이 바람직하다. 스틸 재질의 완충프레임(110)은 차량 충돌시 충돌에너지를 흡수하면서 압착되어 변형되는 구조이므로, 스틸의 항복에너지를 이용하여 차량 충격을 효과적으로 완충할 수 있는 우수한 효과를 구현한다.The buffer frame 110 is preferably made of a steel material. Since the shock absorbing frame 110 made of steel is compressed and deformed while absorbing crash energy during a vehicle crash, the shock absorbing frame 110 realizes an excellent effect of effectively cushioning a vehicle shock using the yield energy of steel.

이러한 완충프레임(110)은 전방으로 돌출 형성되는 제1 굴곡부(111)와, 제1 굴곡부(111)의 하방향으로 절곡 형성되는 제2 굴곡부(112)와, 범퍼 백빔(200)에 밀착되도록 제1 굴곡부(111) 및 제2 굴곡부(112)에 절곡 형성된 고정편(113)으로 구성된다. The buffer frame 110 may be formed to be in close contact with the first bent part 111 protruding forward, the second bent part 112 formed bent downward of the first bent part 111, and the bumper back beam 200. It consists of the fixing piece 113 bent in the 1st bending part 111 and the 2nd bending part 112. As shown in FIG.

그리고 이 완충프레임(110)에는 변형홀부(114)가 형성될 수 있다. 이 변형홀부(114)는 완충프레임(110)에 전체적으로 형성되는 복수의 홀 형태로 구성되어, 차량 충돌시 변형이 쉽게 이루어지도록 한다. 따라서, 변형홀부(114)가 형성된 완충프레임(110)은 변형홀부(114)가 형성되지 아니한 완충프레임(110)에 비해 쉽게 외부충격에 변형되므로, 차량 충돌시 보행자의 다리하부가 안정적으로 보호되도록 한다.In addition, a deformation hole 114 may be formed in the buffer frame 110. The deformed hole 114 is configured in the form of a plurality of holes formed in the buffer frame 110 as a whole, so that deformation is easily made in the event of a vehicle crash. Accordingly, the buffer frame 110 having the deformation hole 114 is easily deformed to the external impact compared to the buffer frame 110 in which the deformation hole 114 is not formed, so that the lower leg of the pedestrian is stably protected during a vehicle crash. do.

한편, 범퍼 백빔(200)의 후방측에는 크래쉬 박스(510)와 프론트 엔드 모 듈(500)이 각각 배치되고, 업서버 폼제(120)의 하측에는 로어 스티프너(400)가 위치된다. 이 로어 스티프너(400)는 차량이 보행자와 충돌하는 경우, 범퍼가 보행자의 무릎 아래의 다리를 치게 되는데, 이때, 스티프너(400)는 보행자의 다리에 과도한 모멘트가 발생되지 않도록 하여 무릎의 인대 파열 및 무릎뼈의 파손을 방지하는 역할을 한다.Meanwhile, the crash box 510 and the front end module 500 are disposed at the rear side of the bumper back beam 200, and the lower stiffener 400 is positioned below the upserver foam 120. The lower stiffener 400 is a bumper hit the leg under the pedestrian's knee when the vehicle collides with the pedestrian, at this time, the stiffener 400 prevents excessive moment in the leg of the pedestrian and tears ligaments of the knee and Prevents breakage of the knee bone.

이와 같은 구성으로 이루어진 본 발명의 작동 과정을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

도 5a는 에너지 업서버가 폼제만 구성된 경우, 레그폼 충돌시험에 대한 결과를 나타낸 도면이고, 도 5b는 본 발명에 따라 에너지 업서버가 폼제 및 완충프레임으로 구성된 경우, 레그폼 충돌시험에 대한 결과를 나타낸 도면이며, 도 6은 도 5a 및 도 5b에 대한 결과를 비교하여 나타낸 레그폼의 감가속도 그래프이다.Figure 5a is a view showing the results for the leg-form crash test, when the energy upserver is configured only with foam, Figure 5b is a result for the leg-form crash test, when the energy upserver is configured with foam and buffer frame according to the present invention 6 is a graph illustrating accelerations of legs shown in comparison with the results of FIGS. 5A and 5B.

도 5a 및 도 5b에 도시된 바와 같이, 실제 차량이 보행자와 부딪칠 경우 그 상해치를 비교해 보면, 에너지 업서버가 폼제(120')만으로 구성된 경우(도 5a)보다, 본 발명에 따라 에너지 업서버가 업서버 폼제(120) 및 완충프레임(110)으로 구성된 경우(도 5b)가 레그 폼(20)의 굽힘 각도가 더 적은 것으로 나타났다. 5A and 5B, when the actual vehicle collides with the pedestrian, comparing the injury value, the energy upserver according to the present invention is compared with the case where the energy upserver is configured only with foam 120 '(FIG. 5A). The bending angle of the leg foam 20 was found to be smaller when the upserver foam 120 and the buffer frame 110 were formed (FIG. 5B).

즉, 본 발명이 레그 폼(20)의 굽힘 각도가 더 적은 것으로 나타남에 따라, 보행자에게 적은 상해를 줄 것으로 예상된다. 이는 레그 폼(20)을 이용한 실차 실험시, 보행자의 다리에 해당하는 레그 폼(20)의 굽힘 각도가 크면 클수록 보행자에게 큰 상해를 줄 것으로 판단되기 때문이다.That is, as the present invention shows that the bend angle of the leg foam 20 is less, it is expected to cause less injury to pedestrians. This is because when the actual vehicle experiment using the leg form 20, the larger the bending angle of the leg form 20 corresponding to the leg of the pedestrian, the greater the injury to the pedestrian.

특히, 도 6에 도시된 바와 같이, 에너지 업서버가 폼제(120')만으로 구성된 경우의 그래프(a)에서는, a1 구간에서 폼제(120')의 충돌 에너지가 흡수되는데 반하여, 에너지 업서버가 업서버 폼제(120) 및 완충프레임(110)으로 구성된 경우의 그래프(b)에서는, b1 구간에서 스틸 재질의 항복 에너지를 이용하여 완충프레임이 충돌 에너지를 흡수하는 것임을 알 수 있다.In particular, as shown in FIG. 6, in the graph (a) in which the energy upserver is composed of only the foam agent 120 ', the collision energy of the foam agent 120' is absorbed in the a1 section, whereas the energy upserver is up. In the graph (b) in the case of the server foam agent 120 and the buffer frame 110, it can be seen that the buffer frame absorbs the collision energy using the yield energy of the steel material in the section b1.

결국, 본 발명의 충돌시험에 따르면, 에너지 업서버가 업서버 폼제(120) 및 완충프레임(110)으로 구성된 경우 감가속도가 충돌 초기에 상승되고, 충돌 후기에 감소하는 현상이 나타남에 따라, 보행자에게 가해지는 최대 감가속도를 적게 하므로 보행자의 다리하부에 대한 상해치를 줄일 수 있는 것이다.As a result, according to the crash test of the present invention, when the energy upserver is configured with the upserver foam 120 and the buffer frame 110, the deceleration is increased at the beginning of the collision and decreases later in the collision. Since the maximum deceleration applied to the vehicle is reduced, the injury to the lower part of the leg of the pedestrian can be reduced.
