차량용 범퍼의 임팩트빔구조Impact Beam Structure of Bumper for Vehicle

본 고안은 차량의 전측 소정부위에 구비되는 범퍼의 임팩트빔구조에 관한 것으로, 특히 범퍼에 구비되는 임팩트빔의 내측에 중공형 강도보강재를 구비하여 차량의 충돌시 발생되는 물리적 충격으로 부터 운전자 및 탑승자를 안전하게 보호할 수 있게 하도록 한 차량용 범퍼의 임팩트빔구조에 관한 것이다.The present invention relates to an impact beam structure of a bumper provided at a predetermined portion of the front side of a vehicle, and in particular, a hollow strength reinforcement material is provided inside the impact beam provided at the bumper to prevent the driver and the occupant from the physical impact generated during the collision of the vehicle. The impact beam structure of the bumper for a vehicle to enable the safe protection of the.

일반적으로, 도 1에 도시된 바와 같이 차량은 충돌로 부터 운전자 및 탑승자를 안전하게 보호하기 위해 프레임(1)을 이루는 롱지튜디널부재(2)의 전측에 고정되는 스테이(Stay)부(3)에 충격완화용 범퍼(4)가 장착되는 바 상기 범퍼(4)는 대별하여 차량의 실내로 침입되는 물리적 충격을 차단하는 내외측 제 1,2임팩트빔(Impact Beam)(5,6)과, 상기 제 1,2임팩트빔(5,6)에 충격이 가해지기에 앞서 우선적으로 물리적 충격을 흡수하는 에너지업소버(7)와, 상기 에너지업소버(7)의 이탈을 방지함과 더불어 밖으로 노출되는 것을 미려하게 커버하는 폴리머페이시어(8)로 이루어지게 된다.In general, as shown in FIG. 1, the vehicle is mounted on a stay part 3 fixed to the front side of the long ground member 2 that forms the frame 1 to protect the driver and the occupant from collision. Shock-absorbing bumper (4) is mounted to the bumper (4) and the inner and outer first and second impact beam (Impact Beam) (5, 6) to block the physical shock that enters the interior of the vehicle roughly, and Before the impact is applied to the first and second impact beams 5 and 6, the energy absorber 7 which absorbs the physical shock preferentially and prevents the energy absorber 7 from being detached and are exposed to the outside. It is made of a polymer facer 8 to cover.

특히, 상기 제 1,2임팩트빔(5,6)은 상호 구조적으로 강도보강될 수 있게 상하측에 동일체로 플랜지부(9)가 구비되고 상기 제 1임팩트빔(5)의 좌우 전측 수직부(10)에는 각각 차량의 턴시그널램프(도시되지 않음)의 장착에 따른 작업공간로로 이용될 수 있게 소정크기의 관통구(11)가 형성되어 있다.Particularly, the first and second impact beams 5 and 6 are provided with flange parts 9 on the upper and lower sides of the first and second impact beams 5 and 6 in the same body so as to be mutually structurally strengthened. 10, a through hole 11 of a predetermined size is formed so as to be used as a work space according to mounting of turn signal lamps (not shown) of the vehicle.

그러나, 일반적으로 차량이 2.5 MPH(Miles Per Hour)의 경미한 충돌에도 범퍼(4)의 제 1,2임팩트빔(5,6)이 차량의 실내측 방향으로 밀려 차체에 손상을 주게됨에 따라 차량의 수리비가 증가됨은 물론 차량의 급속한 충돌시에 더욱더 차량의 실내측으로 범퍼(4)가 심하게 밀려 궁극적으로 차량의 운전자와 탑승자의 신체에 손상을 주게 되는 문제점이 있었다.However, in general, even when the vehicle has a slight collision of 2.5 MPH (Miles Per Hour), the first and second impact beams 5 and 6 of the bumper 4 are pushed toward the inside of the vehicle to damage the vehicle body. As well as an increase in repair costs, there is a problem in that the bumper 4 is severely pushed to the interior side of the vehicle at the time of the rapid collision of the vehicle, which ultimately damages the body of the driver and the occupant of the vehicle.

이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 차량의 충돌시 발생되는 물리적 충격을 강력히 차단하여 차량의 운전자 및 탑승자를 좀더 안전하게 보호할 수 있게 하도록 한 차량용 범퍼의 임팩트빔구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and provides an impact beam structure of a bumper for a vehicle so that the physical shock generated during a collision of the vehicle is strongly blocked to protect the driver and the occupant of the vehicle more safely. Has its purpose.

상기와 같은 목적을 달성하기 위한 본 고안은 범퍼의 폴리머페이시어측 에너지업소버와 차량의 프레임측 스테이부의 사이에 구비되는 제 1,2임팩트빔의 충격강도를 높일 수 있도록 상기 제 1,2임팩트빔의 사이에 중공형 강도보강재가 구비되되, 상기 중공형 강도보강재는 양단에 상기 제 1,2임팩트빔들중의 한곳 내벽에 고정될 수 있게 일정크기로 눌려져 이루어지는 프래트부가 각각 구비되는 것을 특징으로 한다.The present invention for achieving the above object is to increase the impact strength of the first and second impact beams provided between the polymer facer side energy absorber of the bumper and the frame side stay of the vehicle. Between the hollow strength reinforcement is provided, the hollow strength reinforcement is characterized in that each side is provided with a pressing portion is pressed to a certain size to be fixed to the inner wall of one of the first and second impact beams at both ends. do.

이하, 본 고안의 바람직한 실시예를 첨부된 예시도면에 의거하여 상세히 설명한다. 도 2 및 도 3에 도시된 바와 같이 차량의 충돌시 발생되는 물리적 충격이 차량의 실내측으로 침입(Intrusion)되지 않도록 범퍼(4)의 폴리머페이시어(8)측 에너지업소버(7)와 차량의 프레임(1)측 스테이부(3)의 사이에 구비되는 제 1,2임팩트빔(5,6)의 내측에는 중공형 강도보강재(12)가 추가로 구비되는 것이 바람직하다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As illustrated in FIGS. 2 and 3, the energy absorber 7 of the bumper 4 and the energy absorber 7 of the bumper 4 and the frame of the vehicle do not intrude into the interior side of the vehicle. (1) Preferably, the hollow strength reinforcing material 12 is further provided inside the first and second impact beams 5 and 6 provided between the side stay portions 3.

특히, 상기 중공형 강도보강재(12)는 상기 제 1,2임팩트빔(5,6)의 내측 한곳에 양단이 각각 스폿웰딩될 수 있도록 상기 중공형 강도보강재(12)의 양단에는 일정크기로 눌려져 이루어지는 프래트(Flat)부(13)가 각각 형성되게 된다.Particularly, the hollow strength reinforcement 12 is pressed to both ends of the hollow strength reinforcement 12 so that both ends of the hollow strength reinforcement 12 can be spot welded to one inner side of the first and second impact beams 5 and 6. The flat part 13 is formed, respectively.

이때 참고로, 상기 중공형 강도보강재(12)는 속이 비는 구조로 되어 있어 물리적으로 충격강도에 강해질 수 있게 된다.In this case, the hollow strength reinforcing material 12 has a hollow structure so that it can be physically strong in impact strength.

위와 같이 구성된 본 고안의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

차량이 2.5MPH 속도의 경미한 충돌 또는 급속한 충돌시에도 차량의 범퍼(4)를 통해 밀려들어오는 침입력(Intrusion force)이 일차로 범퍼(4)의 폴리머페이시어(8)측 에너지업소버(7)에 의해 완화된후 상기 에너지업소버(7)와 차량의 프레임(1)측 스테이부(3)의 사이에 구비된 제 1,2임팩트빔(5,6)과 상기 제 1,2임팩트빔(5,6)의 사이에 추가로 구비된 중공형 강도보강재(12)에 의해서 현저히 줄어들 수 있게 된다.Intrusion force, which is pushed through the bumper 4 of the vehicle even in the case of a slight collision or a rapid collision at a speed of 2.5 MPH, is primarily applied to the energy absorber 7 on the polymer facer 8 side of the bumper 4. After being relaxed by the first and second impact beams 5 and 6 and between the energy absorber 7 and the frame 1 side stay part 3 of the vehicle. 6) can be significantly reduced by the hollow strength reinforcing material 12 provided between.

이때, 상기 중공형 강도보강재(12)는 양단에 형성된 프래트부(13)가 상기 제 1,2임팩트빔(5,6)의 내측 한곳에 용접되어 있어 차량의 충돌시 발생되는 물리적 충격에 좀더 견고해질 수 있게됨과 더불어 속이 비어 있음으로 인해 물리적 충격에 의한 변화의 영향도 덜 받게 된다.In this case, the hollow strength reinforcing material 12 is welded to the inner portion of the first and second impact beams 5, 6 formed in the front end portion 13 formed on both ends is more robust to the physical impact generated during the collision of the vehicle In addition to being able to do so, the hollow is also less affected by changes caused by physical shocks.

위와 같이, 본 고안에 의한 차량용 범퍼의 임팩트빔구조는 범퍼(4)의 폴리머페이시어(8)측 에너지업소버(7)와 차량의 프레임(1)측 스테이부(3)의 사이에 구비되는 제 1,2임팩트빔(5,6)의 충격강도를 높일 수 있도록 상기 제 1,2임팩트빔(5,6)의 사이에 중공형 강도보강재(12)가 구비되되, 상기 중공형 강도보강재(12)는 양단에 상기 제 1,2임팩트빔(5,6)들중의 한곳 내벽에 고정될 수 있게 일정크기로 눌려져 이루어지는 프래트부(13)가 각각 구비됨으로써 차량의 충돌시 발생되는 물리적 충격이 상기 중공형 강도보강재(12)에 의해 좀더 강력히 차단될 수 있게 되어 차량의 운전자 및 탑승자가 좀더 안전하게 보호될 수 있게 되는 효과가 있다.As described above, the impact beam structure of the bumper for a vehicle according to the present invention is provided between the polymer absorber 8 side energy absorber 7 of the bumper 4 and the stay portion 3 of the frame 1 side of the vehicle. The hollow strength reinforcement 12 is provided between the first and second impact beams 5 and 6 so as to increase the impact strength of the first and second impact beams 5 and 6. ) Is provided with both sides of the plate portion 13, which is pressed to a certain size so as to be fixed to an inner wall of one of the first and second impact beams 5 and 6, respectively, so that the physical impact generated during the collision of the vehicle Since the hollow strength reinforcing material 12 can be more strongly blocked, the driver and the passenger of the vehicle can be more safely protected.
