Description
본 발명은 자동차용 범퍼에 관한 것이며, 상세하게는 다수의 공동을 형성한 백빔을 구비한 자동차용 범퍼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bumpers for automobiles and, more particularly, to bumpers for automobiles having a back beam formed with a plurality of cavities.
주지하는 바와 같이 자동차의 보디의 전후에는 범퍼를 설치하여 충돌시 충격 에너지를 흡수함으로써 탑승자를 보호하고, 다른 차에 미치는 충격 에너지를 경감하고 있다.As is well known, bumpers are provided before and after the body of the vehicle to protect the occupants by absorbing the impact energy during a collision, thereby reducing the impact energy on other vehicles.
종래의 범퍼는 도 5 및 도 6에 도시한 바와 같이 합성수지제 범퍼 커버(30)와 금속제 백빔(31) 사이에 공동을 형성하여 상기 공동에 합성수지제 에너지 압소버(32)를 금속제 백빔(31)에 지지시켜 배치하고, 상기 금속제 백빔(31)의 후면 양측에 범퍼 스테이(33)(33')를 볼트(34)로 결합하여 상기 범퍼 스테이(33)(33')를 사이드 멤버 등의 보디(35)에 볼트(36)로 결합하는 것이 주류를 이루고 있다.The conventional bumper forms a cavity between the synthetic bumper cover 30 and the metal back beam 31 as shown in FIGS. 5 and 6 to form a synthetic energy absorber 32 in the cavity. The bumper stays 33 and 33 'are bolted to both sides of the rear surface of the metal back beam 31, and the bumper stays 33 and 33' are attached to a body such as a side member. Coupling 35 to bolt 36 is the mainstream.
상기한 범퍼는 충돌시 충격 에너지는 에너지 압소버(32), 백빔(31) 및 범퍼 스테이(33)(33')의 결합부에서 차례로 분산 흡수함과 동시에 나머지 충격 에너지는 보디(35)에서 분산 흡수되는 것이다.In the bumper, the impact energy at the time of impact is dispersed and absorbed in turn at the coupling portion of the energy absorber 32, the back beam 31, and the bumper stays 33 and 33 ', while the remaining impact energy is dispersed in the body 35. It is absorbed.
그러나 상기한 범퍼는 정면 충돌시 탑승자의 상해치 및 다른 차에 미치는 충격 에너지의 경감은 양호하지만 다음과 같은 문제점이 있는 것이다.However, the bumper is good in reducing the impact energy on the passenger's injury value and other cars during the frontal collision, but has the following problems.
첫째, 에너지 압소버(32)는 합성수지 단일 발포 폼으로 형성되어 있음으로 충격 에너지 흡수효과가 작아서 자동차와 보행자가 충돌하였을 때 보행자의 상해치가 커지게 되며, 특히 소형차는 에너지 압소버(32)의 폭에 제한을 받음으로 보행자의 상해치가 더욱더 커지게 되는 것이다.First, since the energy absorber 32 is formed of a synthetic resin single foam, the impact energy absorption effect is small, so that the injury value of the pedestrian is increased when the car and the pedestrian collide with each other, and in particular, the compact car has the width of the energy absorber 32. In this case, the injury value of pedestrians is getting bigger.
둘째, 에너지 압소버(32)는 백빔(31)에 지지만 되어 있음으로 오프셋(off set) 충돌시 충돌부위가 집중하중을 받으면서 타측으로 충격 에너지의 흡수 없이 밀리기 때문에 오프셋 충돌시의 충격 에너지 흡수는 백빔(30)에 거의 의존함으로써 탑승자의 상해치가 커지고 다른 차에 미치는 충격 에너지 흡수가 취약하게 되는 것이다.Second, since the energy absorber 32 is built on the back beam 31, the impact portion absorbs the impact energy during offset offset because the impact portion is pushed to the other side while absorbing the concentrated load during offset offset collision. By almost relying on (30), the injury value of the occupant becomes large and the shock energy absorption to other cars becomes weak.
본 발명은 상기한 문제점을 시정하여, 보행자, 탑승자 및 다른 차에 미치는 충격 에너지 흡수를 양호하게 하고, 구조를 단순화한 자동차용 범퍼를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention aims to provide a bumper for automobiles that corrects the above problems, improves the absorption of impact energy on pedestrians, occupants and other cars, and simplifies the structure.
본 발명의 다른 목적은 오프셋 충돌시에도 충격 에너지 흡수를 양호하게 한 자동차용 범퍼를 제공하는 것이다.Another object of the present invention is to provide a bumper for automobiles which has a good impact energy absorption even in an offset collision.
상기한 목적을 달성하기 위하여, 본 발명은 합성수지제 범퍼 커버와, 상기 범퍼 커버의 내부에 배치되는 다수의 공동을 형성한 합성수지제 백빔과, 상기 합성수지제 백빔의 일측에 설치한 금속제 충격 흡수판으로 구성한 것이다.In order to achieve the above object, the present invention provides a synthetic resin bumper cover, a synthetic resin back beam formed of a plurality of cavities disposed inside the bumper cover, and a metal shock absorbing plate provided on one side of the synthetic resin back beam. It is made up.

1 : 범퍼 커버10 : 합성수지제 백빔12 : 공동DESCRIPTION OF SYMBOLS 1 Bumper cover 10 Synthetic resin back beam 12 Cavity
16, 16' : 금속제 충격 흡수판16, 16 ': metal shock absorber
본 발명은 도 1 내지 도 4에 도시한 바와 같이 통상의 합성수지제 범퍼 커버(1)와, 합성수지제 백빔(10)으로 대별된다.The present invention is roughly divided into a conventional synthetic resin bumper cover 1 and a synthetic resin back beam 10 as shown in Figs.
상기 합성수지제 백빔(10)은 백빔 본체(11)의 내부에 다수의 공동(12)을 백빔 본체(11)와 일체로 형성하고, 백빔 본체(11)의 일측 즉 프론트 범퍼에 적용시에는 후방측에, 리어 범퍼에 적용시는 전방측에 백빔 본체(11)의 길이방향을 따라 금속제 충격 흡수판(16)(16')을 삽입한 것이다.The synthetic resin back beam 10 has a plurality of cavities 12 formed integrally with the back beam main body 11 inside the back beam main body 11, and is applied to one side of the back beam main body 11, that is, the rear side when applied to the front bumper. In the case of application to the rear bumper, the metal shock absorbing plates 16 and 16 'are inserted along the longitudinal direction of the back beam body 11 on the front side.
상기 공동(12)은 하니컴 형상 이외에 삼각형상, 4각형상 등 임의의 형상으로 형성하고, 그 중앙에 연결부(13)를 형성하여 상하에 상하 공동(14)(14')을 형성한 것이다.In addition to the honeycomb shape, the cavity 12 is formed in an arbitrary shape such as a triangular shape or a quadrangular shape, and a connecting portion 13 is formed at the center thereof to form upper and lower cavities 14 and 14 '.
상기 금속제 충격 흡수판(16)(16')은 호상으로 형성하여 그 돌출부를 보디의전방측 또는 후방측을 향하도록 공동(12)에 홈(15)(15')을 형성하여 삽입하며, 상기와 같이 홈(15)(15')에 금속제 충격 흡수판(16)(16')을 삽입할 때 홈(15)(15') 부분은 연결부(13)를 형성하지 않고 하부 공동(14')의 홈(15)(15') 하부에 연결편(17)(17')를 형성하여 삽입한 것이다.The metal shock absorbing plates 16 and 16 'are formed in an arc shape, and the grooves 15 and 15' are formed and inserted into the cavity 12 so that the protrusions face the front side or the rear side of the body. When the metal shock absorbing plates 16 and 16 'are inserted into the grooves 15 and 15' as shown in the drawing, the grooves 15 and 15 'portions do not form the connecting portion 13, but the lower cavity 14'. The connecting pieces 17 and 17 'are formed to be inserted into the grooves 15 and 15' below.
그리고 상기 금속제 충격 흡수판(16)(16')은 강도와 탄성이 양호한 탄소강 또는 스프링 강을 사용하는 것이 바람직하다. 또한 금속제 충격 흡수판(16)(16')은 공동(12)에 홈(15)(15')을 형성하여 삽입하는 외에 백빔(10)을 사출성형 등으로 형성할 때 금형에 인써트한 후 백빔(10)과 일체로 형성할 수 있는 것이다.The metal shock absorbing plates 16 and 16 'are preferably made of carbon steel or spring steel having good strength and elasticity. In addition, the metal shock absorbing plates 16 and 16 'are formed by inserting grooves 15 and 15' into the cavity 12 and inserting the back beam 10 into the mold when the back beam 10 is formed by injection molding. It can be formed integrally with (10).
상기한 금속제 충격 흡수판(16)(16')은 2개를 설치한 것에 대하여 도시하고 설명하였지만 차종에 따라 적어도 1개 이상 5개 정도까지 설치할 수 있는 것이다.The metal shock absorbing plates 16 and 16 ′ described above have been described with reference to the installation of two metal shock absorbing plates 16, 16 ′.
또한 상기 백빔 본체(11)의 양단부에는 백빔 본체(11)보다 그 폭이 작은 결합부(18)(18')를 백빔 본체(11)와 일체로 형성하여 결합공(19)을 형성하여서 사이드 멤버 등의 보디(20)에 직접 볼트(21)로 체결 결합한 것이다.In addition, at both ends of the back beam main body 11, coupling portions 18 and 18 'having a width smaller than that of the back beam main body 11 are integrally formed with the back beam main body 11 to form the coupling holes 19 to form side members. The bolts 21 are directly coupled to the body 20 of the back.
이상과 같은 본 발명은 보행자가 범퍼에 충돌하거나 범퍼가 보행자에 충돌하였을 때(이하 프론트 범퍼를 기준으로만 설명함) 보행자는 백빔 본체(11)의 전방부에 충돌하고, 백빔 본체(11)의 전방부는 하니컴 등의 공동(12)만이 형성되어 있음으로 변형이 용이하기 때문에 충격 에너지 흡수가 양호하여 상해치를 경감할 수 있는 것이다.According to the present invention as described above, when the pedestrian collides with the bumper or the bumper collides with the pedestrian (hereinafter, only the front bumper will be described), the pedestrian collides with the front part of the back beam body 11, Since only the cavity 12, such as a honeycomb, is formed in the front part, since deformation is easy, shock energy absorption is good and an injury value can be reduced.
그리고 범퍼가 다른 차 또는 구축물 등에 충돌하였을 때에는 1차로 백빔 본체(11)의 전방부에서 충격을 흡수하고 전방부에서 흡수되지 못한 충격은 금속제 충격 흡수판(16)(16')에서 흡수함으로써 탑승자의 상해치 및 다른 차의 충격을 양호하게 경감할 수 있는 것이다.When the bumper collides with another vehicle or structure, the shock absorber is primarily absorbed by the front part of the back beam body 11 and the shock which is not absorbed by the front part is absorbed by the metal shock absorber plates 16 and 16 '. It is possible to satisfactorily reduce the injury value and the impact of other cars.
이때 금속제 충격 흡수판(16)(16')은 전방으로 돌출되는 호상으로 형성되어 있음으로 완충효과가 양호하게 되는 것이며, 금속제 충격 흡수판(16)(16')은 차종에 따라 그 수를 증감할 수 있음으로 고속 충돌시에도 탑승자의 상해치를 양호하게 경감할 수 있는 것이다.At this time, since the metal shock absorbing plates 16 and 16 'are formed in an arc shape projecting forward, the buffer effect is good, and the number of metal shock absorbing plates 16 and 16' increases and decreases depending on the vehicle type. By doing so, it is possible to satisfactorily reduce the injury value of the occupant even in a high-speed collision.
그리고 오프셋 충돌시에 일측 결합부(18)에 집중하중이 작용하면 백빔 본체(11)와 금속제 충격 흡수판(16)(16')의 양단은 보디(20)에 볼트(21)로 결합되어 있음으로 일측 결합부(18)에 작용한 집중하중이 타측 결합부(19)에 전달되어 타측 결합부(19)가 변형하면서 충격을 흡수함으로써 오프셋 충돌시에도 충격 흡수가 양호하게 되는 것이다.When the concentrated load acts on one side coupling portion 18 during the offset collision, both ends of the back beam body 11 and the metal shock absorbing plates 16 and 16 'are coupled to the body 20 by bolts 21. As a result, the concentrated load acting on the one side coupling portion 18 is transmitted to the other side coupling portion 19 to absorb the shock while the other side coupling portion 19 deforms, so that the shock absorption is good even at the time of offset collision.
또한 본 발명은 범퍼 커버와 백빔으로 구성하고 백빔을 직접 보디에 결합함으로써 범퍼 및 그 결합구조가 단순화되는 것이다.In addition, the present invention consists of a bumper cover and a back beam, and the bumper and its coupling structure are simplified by directly coupling the back beam to the body.
이상과 같이 본 발명은 백빔을 다수의 공동으로 형성하고 일측에 금속제 충격 흡수판을 설치하여 충격 에너지 흡수를 양호하게 하였음으로 보행자 보호 및 충돌시의 안전에 만전을 기할 수 있고, 구조가 단순화되어 원가를 절감할 수 있는 것이다.As described above, the present invention forms a plurality of cavities of the back beam and installs a metal shock absorber on one side to improve the absorption of impact energy, thereby ensuring pedestrian protection and safety at the time of collision, and the structure is simplified to reduce costs. To reduce the cost.
또한 백빔의 양단을 보디에 직접 결합함으로써 오프셋 충돌시 일측 결합부에 작용하는 집중하중을 타측 결합부에 전달할 수 있기 때문에 충격 에너지 흡수가 양호하게 되는 것이다.In addition, by directly coupling both ends of the back beam to the body, it is possible to transfer the concentrated load acting on one coupling portion to the other coupling portion during offset collision, so that the impact energy absorption is good.
