Description
본 발명은 자동차의 범퍼에 관한 것으로서, 특히 후면 충돌시 충격을 완충시키는 리어 범퍼(rear bumper)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bumpers in motor vehicles, and more particularly to rear bumpers that cushion shocks in rear collisions.
일반적으로 자동차의 범퍼(bumper)는 자동차의 전면과 후면에 마련되어 충돌사고시 충격력을 흡수함으로써 운전자와 탑승자의 보호 그리고 차체의 변형을 방지하는 기능을 수행한다.In general, bumpers of a vehicle are provided at the front and rear of the vehicle to absorb impact force during a crash, thereby protecting the driver and the occupant and preventing deformation of the vehicle body.
이러한 자동차의 범퍼에 있어서, 특히 리어 범퍼는 크게 2가지 타입을 대별된다.In the bumpers of such automobiles, the rear bumpers in particular are largely divided into two types.
즉, 커버상에 완충을 위한 별도의 업소버를 결합시킨후 이를 백 패널에 결합시키는 타입과, 업소버를 개재하지 않고 직접 커버를 브래킷을 통해 백 패널에 결합시키는 타입이 있다.That is, there is a type that couples a separate absorber for cushioning on the cover and then couples it to the back panel, and a type that directly couples the cover to the back panel through the bracket without the absorber.
도 1 및 도 4에는 이러한 자동차의 리어 범퍼중 특히 업소버를 채용한 타입의 리어 범퍼를 나타내 보였다.1 and 4 show a rear bumper of a type employing an absorber among the rear bumpers of such a vehicle.
이는, 자동차의 백 패널(back panel;10)에 다수의 브래킷(bracket;미도시)을 통해 범퍼 커버(bumper cover;20)가 결합된다.The bumper cover 20 is coupled to a back panel 10 of a vehicle through a plurality of brackets (not shown).
이 범퍼 커버(20)의 외측면에는 번호판을 설치하기 위하여 내측으로 경사진 경사부(21)가 형성된다.An inclined portion 21 inclined inward is formed on the outer surface of the bumper cover 20 to install the license plate.
한편, 범퍼 커버(20)와 백 패널(10) 사이에는 범퍼 빔(bumper beam;30)이 브래킷(40)을 통해 범퍼 커버(20)에 결합되며, 범퍼 커버(20)와 범퍼 빔(30) 사이에는 압소버(absorber;50)가 개재된다.Meanwhile, a bumper beam 30 is coupled to the bumper cover 20 through the bracket 40 between the bumper cover 20 and the back panel 10 and the bumper cover 20 and the bumper beam 30. An absorber 50 is interposed therebetween.
이때 압소버(50)는 범퍼 커버(20)의 경사부(21)가 형성된 부위측을 제외한 상,하측에 개재된다.At this time, the absorber 50 is interposed on the upper side and the lower side except for the site side where the inclined portion 21 of the bumper cover 20 is formed.
이러한 종래 리어 범퍼는, 후방 충돌시 범퍼 커버(20)와 압소버(50)를 통해1차적으로 충격을 완충시키고, 동시에 범퍼 빔(30)을 통해 백 패널(10)로 충격을 분산시킴으로서 2차로 충격을 완충시키게 되는 것이다.This conventional rear bumper is secondary by dispersing the impact primarily through the bumper cover 20 and the absorber 50 during the rear collision, and simultaneously distributing the impact to the back panel 10 through the bumper beam 30. It will cushion the shock.
그러나 이러한 종래 리어 범퍼에 있어서는, 도시된 바와 같이 범퍼 커버(20)의 경사부(21)로 인하여 후방 충돌시 압소버(50)가 균일하게 충격을 흡수하지 못하고, 경사부(21)를 중심으로 하여 회전함으로서 충격 흡수의 효과가 떨어지는 문제점이 야기되며, 또한 상호간의 체결 부품 예컨대 브래킷(40)의 파손이 유발되는 문제점이 내재되어 있다.However, in the conventional rear bumper, the absorber 50 does not uniformly absorb the shock during the rear collision due to the inclined portion 21 of the bumper cover 20, as shown in the drawing. As a result, the problem that the effect of shock absorption is reduced by the rotation is caused, and also there is a problem that causes the breakage of the fastening parts, for example, the bracket 40 between each other.
이러한 문제점은 저속 충돌시에도 발생되어 수리비가 상승됨으로써 소비자의 불만족을 유발할 뿐만 아니라 상품성 저하의 원인이 되고 있다.These problems are caused even at low speeds and the repair cost is increased, causing not only consumer dissatisfaction but also deteriorating the merchandise.
본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 후방 충돌시 압소버가 회전되는 것을 미연에 방지하여 균일한 충격 흡수를 도모할 수 있도록 함으로써 안정된 완충 효과를 얻을 수 있어 수리비의 상승을 미연에 방지할 수 있는 자동차의 리어 범퍼를 제공함에 그 목적이 있다.The present invention was created to solve such a conventional problem, by preventing the absorber from rotating in the rear impact in advance to achieve a uniform shock absorption to obtain a stable buffering effect to increase the repair cost The purpose is to provide a rear bumper of a vehicle that can be prevented in advance.
상기한 목적을 달성하기 위하여 본 발명은, 자동차의 백 패널상에 양측이 고정 설치되며 외측면에 소정 경사각도로 번호판이 장착되도록 경사부가 형성된 범퍼 커버와; 상기 범퍼 커버의 내측면에 위치되는 범퍼 빔과; 상기 범퍼 커버의 경사부를 제외한 범퍼 빔의 상,하면과 범퍼 커버의 상,하 내측면 사이에 개재되어 충격을 완충시키는 압소버와; 상기 범퍼 빔의 범퍼 커버 경사부 대응위치의 상부 외측면과 압소버의 내측면 사이에 개재되며, 충격시 압소버의 회전을 방지하는 레인포스;로 구성된 것을 그 특징으로 한다.In order to achieve the above object, the present invention includes a bumper cover having both sides fixedly installed on a back panel of an automobile and having an inclined portion such that a license plate is mounted at a predetermined inclination angle on an outer surface thereof; A bumper beam positioned on an inner side of the bumper cover; An absorber interposed between the upper and lower surfaces of the bumper beam except for the inclined portion of the bumper cover and the upper and lower inner surfaces of the bumper cover to cushion the shock; And a rain force interposed between the upper outer surface of the bumper cover inclined portion corresponding position of the bumper beam and the inner surface of the absorber and preventing rotation of the absorber during an impact.

도 1에 참조되고 도 2 및 도 3에서와 같이 본 발명은,1 and the present invention as in FIGS. 2 and 3,
자동차의 백 패널(back panel;10)에 다수의 브래킷(bracket;미도시)을 통해 범퍼 커버(bumper cover;20)가 결합된다.A bumper cover 20 is coupled to a back panel 10 of a vehicle through a plurality of brackets (not shown).
이 범퍼 커버(20)의 외측면에는 번호판을 설치하기 위하여 내측으로 경사진 경사부(21)가 형성된다.An inclined portion 21 inclined inward is formed on the outer surface of the bumper cover 20 to install the license plate.
한편, 범퍼 커버(20)와 백 패널(10) 사이에는 범퍼 빔(bumper beam;30)이 브래킷(40)을 통해 범퍼 커버(20)에 결합되며, 범퍼 커버(20)와 범퍼 빔(30) 사이에는 압소버(absorber;50)가 개재된다.Meanwhile, a bumper beam 30 is coupled to the bumper cover 20 through the bracket 40 between the bumper cover 20 and the back panel 10 and the bumper cover 20 and the bumper beam 30. An absorber 50 is interposed therebetween.
이때 압소버(50)는 범퍼 커버(20)의 경사부(21)가 형성된 부위측을 제외한 상,하측에 개재된다.At this time, the absorber 50 is interposed on the upper side and the lower side except for the site side where the inclined portion 21 of the bumper cover 20 is formed.
그리고 범퍼 빔(30)의 상기 범퍼 커버(20) 경사부(21) 대응위치의 상부 내측면과 압소버(50) 사이에는 실질적으로 본 발명의 특징적인 요소를 갖고 있는 것으로서, 후방 충돌시 압소버(50)가 회전되는 것을 방지하기 위한 레인포스(reinforce;100)가 개재된다.The absorber 50 is substantially between the upper inner surface of the bumper cover 20 corresponding to the inclined portion 21 of the bumper beam 30 and the absorber 50. A reinforce 100 is interposed to prevent 50 from being rotated.
이 레인포스(100)는, 범퍼 빔(30)의 상부 내측면에 끼워 삽입되어 지지되는 고정부(110)와, 이 고정부(110)로 부터 수직 상방으로 일체로 연장되어 압소버(50)의 내측면에 밀착 접촉되는 지지부(120)로 이루어진다.The rain force 100 is fixed to the upper part of the bumper beam 30, the fixing portion 110 is inserted and supported, and from the fixing portion 110 integrally extending vertically upward, the absorber 50 It consists of a support portion 120 in close contact with the inner side of the.
이때 레인포스(100)를 통해서 좀더 효과적인 충격 흡수를 도모할 수 있도록 하기 위하여 레인포스(100)에는 격자(格子)상으로 리브(rib;130)가 일체로 형성되어 다수의 완충 공간부(131)를 형성한다.At this time, in order to achieve more effective shock absorption through the rain force 100, a rib 130 is formed integrally on the lattice in the rain force 100 so that a plurality of buffer space portions 131 are provided. To form.
이와같이 구성된 본 발명은, 후방 충돌시 범퍼 커버(20)와 압소버(50)를 통해 1차적으로 충격을 완충시키고, 동시에 범퍼 빔(30)을 통해 백 패널(10)로 충격을 분산시킴으로서 2차로 충격을 완충시키게 되는 것이다.According to the present invention configured as described above, the shock is primarily absorbed through the bumper cover 20 and the absorber 50 during the rear collision, and at the same time, the shock is distributed to the back panel 10 through the bumper beam 30 in the second way. It will cushion the shock.
한편, 이와같이 충격 흡수를 행하는 과정에서, 압소버(50)는 범퍼 빔(30)과의 사이에 개재된 레인포스(100)에 의해 지지되어 있기 때문에 범퍼 커버(20)의 경사부(21)를 기준으로 하여 회전되지 않게됨으로써 안정된 충격 흡수가 이루어직게 되며, 특히 레인포스(100)에 격자상으로 형성된 리브(130)에 의해 다수의 완충 공간부(131)가 형성됨으로써 이를 통해서는 충격을 좀더 효과적으로 완충시킬 수 있게된다.On the other hand, in the process of absorbing shock in this way, since the absorber 50 is supported by the rain force 100 interposed between the bumper beam 30, the inclined portion 21 of the bumper cover 20 is removed. By not rotating based on the reference, a stable shock absorption is achieved. In particular, a plurality of buffer space portions 131 are formed by the ribs 130 formed in the lattice shape in the rain force 100, thereby effectively impacting the shock. It can be buffered.
이상과 같이 본 발명은, 범퍼 빔의 범퍼 커버 경사부의 대응위치와 압소버 사이에 레인포스가 개재됨으로써 범퍼 커버의 경사부로 인하여 후방충돌시 발생되는 압소버의 회전을 미연에 방지할 수 있게된다.As described above, according to the present invention, the rain force is interposed between the corresponding position of the bumper cover inclined portion of the bumper beam and the absorber, thereby preventing rotation of the absorber generated at the time of rear collision due to the inclined portion of the bumper cover.
따라서 압소버를 통해 균일한 충격 흡수 효과를 얻을 수 있게된다.Therefore, it is possible to obtain a uniform shock absorbing effect through the absorber.
이외에도 레인포스상에 다수의 완충 공간부가 형성됨으로써 이를 통해서 좀더 효과적인 충격 흡수를 얻을 수 있는 이점이 있다.In addition, since a plurality of buffer spaces are formed on the rain force, there is an advantage in that more effective shock absorption can be obtained.
