Description
본 발명은 자동차의 범퍼에 관한 것이다.The present invention relates to a bumper of a motor vehicle.
도 1에서와 같이 일반적으로 자동차의 바디(20) 전면에 범퍼(bumper;10)를 마련하여, 충돌사고시 충격력을 흡수함으로써 운전자와 탑승자를 보호하고 있다.As shown in FIG. 1, a bumper 10 is generally provided on the front of the body 20 of the vehicle to protect the driver and the occupant by absorbing impact force during a crash.
이러한 범퍼의 상세한 구조를 보면, 도 3에서와 같이, 차체 바디(20)의 하부측 좌,우 양측에는 길이 방향을 따라 좌,우 사이드 멤버(side member;1)가 설치된다.Looking at the detailed structure of such a bumper, as shown in FIG. 3, left and right side members 1 are provided on both sides of the lower and left sides of the vehicle body 20 along the length direction.
이 사이드 멤버(1)의 전면에는 백 빔(back beam;2)이 스테이(stay;3)를 통해 고정 설치되고, 백 빔(2)은 범퍼 커버(4)와 결합된다.A back beam 2 is fixedly installed on the front of the side member 1 through a stay 3, and the back beam 2 is coupled to the bumper cover 4.
한편, 백 빔(2)과 스테이(3)는 상호 용접 고정되며, 스테이(3)는 볼트(B)와 너트(N)를 통해 차체 즉, 사이드 멤버(1)에 결합되는 구조를 취하고 있다.On the other hand, the back beam 2 and the stay 3 are welded to each other, the stay 3 has a structure that is coupled to the vehicle body, that is, the side member 1 through the bolt (B) and the nut (N).
미설명부호(5)는 스테이(3)에 마련되어 사이드 멤버(1)에 결합될 때 위치를 안내하기 위한 가이드 핀(guide pin)이다.Reference numeral 5 is a guide pin provided in the stay 3 to guide the position when coupled to the side member (1).
이러한 범퍼는, 정면 충돌이 발생될 때 범퍼 커버(4)를 통해 충격력이 백 빔(2)에 전달되고, 동시에 스테이(3)를 거쳐 사이드 멤버(1)에 분산 흡수됨으로써 충격 완충을 통해 운전자와 탑승자를 보호하게 되는 것이다.Such a bumper, when a frontal collision occurs, the impact force is transmitted to the back beam 2 through the bumper cover 4, and at the same time dispersed and absorbed by the side member 1 via the stay (3) to the driver through the shock buffer It will protect the occupants.
그러나 이러한 종래 범퍼에 있어서는 다음에 열거하는 많은 문제점을 내재하고 있다.However, such a conventional bumper has many problems listed below.
첫째, 백 빔(2)을 사이드 멤버(1)에 결합시키기 위하여 스테이(3)와 볼트(B) 및 너트(N)를 필요로 함으로써 부품수 증가에 따른 코스트 상승과 조립 작업성의 저하를 초래하는 문제점이 있다.First, in order to couple the back beam 2 to the side member 1, the stay 3, the bolt B and the nut N are required, which leads to an increase in cost and a decrease in assembly workability due to an increase in the number of parts. There is a problem.
둘째, 스테이(3)가 백 빔(2)과 사이드 멤버(1) 사이에 개재됨으로써 사이드 멤버(1)를 통한 충격 에너지 흡수 영역이 감소되어 충분한 충격 흡수 효과를 얻지 못하는 문제점이 야기된다.Second, since the stay 3 is interposed between the back beam 2 and the side member 1, the area of impact energy absorption through the side member 1 is reduced, resulting in a problem that a sufficient shock absorption effect is not obtained.
셋째, 백 빔(2)과 스테이(3)에 용접을 위한 플랜지를 각각 형성하여야 함으로써 백 빔(2)의 단면적 감소에 따른 충격 흡수효과의 저해를 초래하는 문제점이있다.Third, there is a problem in that the flanges for welding are formed on the back beam 2 and the stay 3, respectively, thereby causing the impairment of the shock absorbing effect due to the reduction in the cross-sectional area of the back beam 2.
본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 정면 충돌시 충격 흡수효과를 상승시킬 수 있으며, 부품수 감소에 따른 코스트 절감과 조립 작업성의 향상을 꾀할 수 있는 자동차의 범퍼를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, it is possible to increase the shock absorbing effect during a frontal collision, to provide a bumper of a vehicle that can reduce the cost and improve the assembly workability due to the reduction of the number of parts The purpose is.
상기한 목적을 달성하기 위하여 본 발명은, 범퍼 커버의 내측면에 좌,우 방향으로 설치되며, 상,하 양측면에 소정깊이의 걸림홈이 형성된 백 빔과; 자동차의 하부 양측에 길이 방향으로 설치되며, 백 빔과 인접되도록 일단이 연장된 좌,우 사이드 멤버와; 상기 사이드 멤버의 전면에 마련되어 백 빔의 전,후면을 감싸는 형태로 연장되며, 백 빔의 걸림홈과 대응되는 위치에는 걸림돌기가 형성된 레인포스;로 구성된 것을 그 특징으로 한다.In order to achieve the above object, the present invention, the back beam is installed in the left and right directions on the inner surface of the bumper cover, the back beam is formed on both sides of the upper and lower side has a predetermined depth; Left and right side members which are installed at both sides of the lower part of the vehicle in the longitudinal direction and whose one end extends to be adjacent to the back beam; It is provided on the front side of the side member to extend in the form surrounding the front, rear of the back beam, the position corresponding to the locking groove of the back beam;

도 1에 참조되고 도 2에 나타내 보인 바와 같이 본 발명은, 범퍼 커버(4)의 내측면에 좌,우 방향으로 설치되는 백 빔(back beam;100)을 구비한다.As shown in FIG. 1 and shown in FIG. 2, the present invention includes a back beam 100 provided in the left and right directions on the inner surface of the bumper cover 4.
이 백 빔(100)의 상,하 양측면에는 내측으로 절곡된 소정깊이의 걸림홈(110)이 형성된다.The upper and lower side surfaces of the back beam 100 are provided with locking grooves 110 having a predetermined depth bent inwardly.
차체의 하부 양측에는 길이 방향을 따라 좌,우 사이드 멤버(side member;200)가 위치되는 바, 특히 사이드 멤버(200)의 단부는 백 빔(100)과 인접된 위치까지 길게 연장 형성된다.Left and right side members 200 are positioned along both sides of the lower portion of the vehicle body, and in particular, end portions of the side members 200 extend to a position adjacent to the back beam 100.
사이드 멤버(200)의 전면에는 레인포스(renforce;300)가 고정 설치되는 바, 이 레인포스(300)은 백 빔(100)의 상,하 양측면을 감싸는 형태로 연장 형성되며,특히 백 빔(100)의 상,하면에 형성된 걸림홈(110)과 대응되는 내측면에는 이에 탄력적으로 끼워 삽입될 수 있도록 걸림돌기(310)가 일체로 마련된다.The front of the side member 200 is fixed to the rain force (renforce; 300) bar, the rain force 300 is formed to extend in the form surrounding the upper and lower sides of the back beam 100, in particular the back beam ( The locking protrusion 310 is integrally provided on the inner surface corresponding to the locking groove 110 formed on the upper and lower surfaces of the 100 to be elastically inserted thereto.
한편, 백 빔(100)이 안정되게 레인포스(300)상에 결합될 수 있도록 하기 위하여, 백 빔(100)의 상,하면에 가이드 핀(guide pin;120)을 마련하고, 대응되는 레인포스(300)의 전면에는 가이드 구멍(320)을 형성하도록 함이 바람직할 것이다.Meanwhile, to enable the back beam 100 to be stably coupled to the rain force 300, guide pins 120 are provided on upper and lower surfaces of the back beam 100, and the corresponding rain force is provided. It may be desirable to form the guide hole 320 on the front of the (300).
이와같이 구성된 본 발명은, 충돌사고가 발생되며, 범퍼 커버(4)를 통해 백 빔(100)으로 전달되고, 동시에 백 빔(100)과 결합된 레인포스(300)를 거쳐 사이드 멤버(200)로 전달됨으로써 충격 완충의 효과를 얻게된다.According to the present invention configured as described above, a collision accident occurs and is transmitted to the back beam 100 through the bumper cover 4 and at the same time to the side member 200 via the rain force 300 coupled with the back beam 100. By transmitting, the effect of shock absorbing is obtained.
이때 특히 백 빔(100)과 사이드 멤버(200) 사이에는 종래와 같이 별도의 스테이가 개재되지 않고, 사이드 멤버(200)의 전면이 백 빔(100)과 인접되도록 연장 형성된 것이기 때문에 충격 에너지 흡수 영역이 증대되는 효과를 얻게된다.In this case, in particular, between the back beam 100 and the side member 200, there is no separate stay as in the prior art, and since the front surface of the side member 200 extends to be adjacent to the back beam 100, the impact energy absorbing region. This increases the effect.
또한 백 빔(100)이 레인포스(300)와 결합될 때 별도의 볼트와 너트를 사용하지 않고 단순히 끼워 삽입하는 동작을 통해 결합됨으로써 조립 작업성을 향상시킬 수 있게된다.In addition, when the back beam 100 is coupled to the rain force 300, the assembly workability can be improved by being combined by simply inserting and inserting without using a separate bolt and nut.
이상과 같이 본 발명은, 백 빔을 사이드 멤버에 마련된 레인포스에 끼워 삽입하는 것을 통해 장착이 이루어지는 것이어서, 종래와 같이 별도의 볼트와 너트를 채용하는 것에 비교할 때 부품수 감소에 따른 코스트 절감과 특히 조립 작업성을 향상시킨 이점이 있다.As described above, the present invention is carried out by inserting the back beam into the rain force provided in the side member, and thus, the cost reduction due to the reduction in the number of parts, and in particular, in comparison with the conventional bolt and nut is adopted. There is an advantage that the assembly workability is improved.
또한 사이드 멤버가 충분히 길게 연장 형성되어 충분한 충격 에너지 흡수영역을 확보한 것이기 때문에 충돌사고시 운전자 및 탑승자의 보호를 도모한 이점이 있다.In addition, since the side member is formed to extend long enough to secure a sufficient impact energy absorption area, there is an advantage to protect the driver and the occupant in the event of a crash.
