본 발명은 자동차의 후방차체에 관한 것으로, 특히 선단부에 구조적인 강성을 증대시키기 위한 보강비드가 형성되어 후방차체와 결합되도록 하여 자동차의 후방충돌시에 효과적으로 대응할 수 있도록 하는 자동차의 후방차체 보강판넬구조에 관한 것이다.The present invention relates to a rear vehicle body of the vehicle, in particular, the rear body reinforcement panel structure of the vehicle to be effectively coped with the rear collision by forming a reinforcement bead to increase the structural rigidity at the front end to be combined with the rear vehicle body It is about.
종래 자동차에는 충돌시에 탑승자 등을 보다 안전하게 보호하기 위해 차체의 전후방에 범퍼가 장착되어 있는데, 이 범퍼는 외관미를 향상시키기 위해 외측에 부착되는 페시아와, 이 페시아와 결합되어 충격을 1차적으로 흡수하는 충격흡수재 및, 이 충격흡수재의 이면에 결합되어 강성을 보강하면서 충격을 2차적으로 흡수할 뿐만 아니라 여분의 충격을 차체로 분산시켜 완화되도록 하는 충격흡수빔을 갖춘 구조로 되어 있다.Conventional cars are equipped with bumpers in front and rear of the vehicle body in order to more safely protect occupants, etc. in the event of a collision. The bumpers are combined with the fascia attached to the outside to improve the appearance and the impact is primarily A shock absorbing material to absorb and a shock absorbing beam coupled to the rear surface of the shock absorbing material to reinforce the rigidity, not only absorbs the shock secondaryly, but also distributes the extra shock to the vehicle body to mitigate.
그리고 상기 충격흡수재는 차체에 스테이를 개재하여 체결되어 적절히 지지되게 되어 있는데, 상기 후방범퍼가 체결되는 종래의 후방차체는 제2도 및 제3도에 도시된 바와 같이, 후방차체(11)가 ㄴ자 채널형상을 하고서 이 채널내에 구조적인 강성을 증대시키기 위해 보강판넬(12)이 용접으로 취부되게 되어 있다.And the shock absorbing material is fastened through the stay to the vehicle body to be properly supported, the conventional rear vehicle body to which the rear bumper is fastened, as shown in Figures 2 and 3, the rear car body 11 The reinforcement panel 12 is mounted by welding in order to increase the structural rigidity in the channel in the shape of a channel.
그리고 상기 후방차체(11)의 앞쪽 측면에는 플로워판넬의 측면이 부착됨과 더불어 앞쪽 상면에는 전방플로워판넬이 취부되게 되어 있고, 뒷쪽 선단부에는 연장부(13)가 체결되면서 이 연장부(13)의 상면에는 후방플로워판넬이 장착되어 폐공간을 형성하도록 되어 있다.In addition, the front side of the rear vehicle body 11 is attached to the side of the floor panel, and the front upper panel is mounted on the front upper surface, and the extension portion 13 is fastened to the rear end portion of the upper surface of the extension portion 13. It is equipped with a rear follower panel to form a closed space.
그런데 상기한 종래의 후방차체(11)와 그 보강판넬(12)은 길이방향을 따라 후방부가 오목한 홈이 형성되게 절곡되어 절곡부(14)가 형성됨에 따라 자동차의 후방충돌시에 상기 절곡부(14)로 인해 벤딩의 정도가 과도하게 된다고 하는 결점이 있었다.However, the conventional rear vehicle body 11 and the reinforcement panel 12 are bent to form recessed grooves in the rear portion along the longitudinal direction, so that the bent portion 14 is formed, so that the bent portion ( 14) there was a drawback that the degree of bending was excessive.
이에 본 발명은 상기한 결점을 해소하기 위해 안출된 것으로, 선단부에 구조적인 강성을 증대시키기 위해 보강비드가 형성되면서 후방차체와 결합되어 자동차의 후방충돌시에 효과적으로 대응할 수 있도록 하는 자동차의 후방차체 보강판넬구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised to solve the above-described drawbacks, and the rear body reinforcement of the vehicle which can effectively cope with the rear collision of the vehicle is combined with the rear body while the reinforcement bead is formed to increase the structural rigidity at the tip end. The purpose is to provide a panel structure.
상기한 바의 목적을 달성하기 위한 본 발명은, ㄷ자 채널형상을 이루고서 후방범퍼와 결합되어 지지하면서 충돌시에 충격을 흡수하도록 된 후방차체의 구조적인 강성을 증대시키기 위해 후방차체내에 삽입되어 취부되도록 된 자동차의 후방차체 보강판넬에 있어서, 양측 플랜지가 후방차체내에 끼워져 용접될 수 있도록 단면이 ㄷ자 형상을 하고서 상부로부터 하부까지 완만하게 굴곡형성되면서 하단부에는 용접써비홀과 구조적인 강성을 증대시키기 위한 보강비드가 형성되는 한편, 샤시크로스부재와 트레일링 아암을 장착하기 위한 다수개의 너트가 용접으로 취부된 구조로 되어 있다.The present invention for achieving the above object is inserted into the rear body to increase the structural rigidity of the rear body to form a U-shape channel shape, coupled with the rear bumper and absorb the impact during a collision. In the rear body reinforcement panel of the automobile, the cross section is shaped like a c-shape so that both flanges can be inserted into the rear body to be welded and bent smoothly from the top to the bottom to increase the welding service hole and structural rigidity at the lower end. While reinforcing beads are formed, a plurality of nuts for mounting the chassis cross member and the trailing arm are welded.
이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 후방차체의 보강판넬의 개략적인 사시도인 바, 즉 양측 플랜지(1)가 후방차체내에 끼워져 용접될 수 있도록 단면이 ㄷ자 형상을 하고서 상부로부터 하부까지 완만하게 굴곡형성되면서 하단부에는 용접써비홀(2)과 구조적인 강성을 증대시키기 위한 보강비드(4)가 형성되는 한편, 샤시크로스부재와 트레일링 아암을 장착하기 위한 다수개의 너트(3)가 용접으로 취부된 구조로 되어 있다.1 is a schematic perspective view of a reinforcement panel of a rear vehicle according to the present invention, that is, the lower end portion is gently curved from the top to the bottom while having a c-shaped cross section so that both flanges 1 may be inserted into and welded in the rear vehicle. In the welder hole 2 and a reinforcement bead 4 for increasing structural rigidity are formed, a plurality of nuts 3 for mounting the chassis cross member and the trailing arm are welded. have.
상기한 구조로 된 본 발명에 따른 보강판넬은 상기 보강비드(4)에 의해 구조적인 강성이 증대되게 되는 바, 이 보강판넬은 후방차체의 채널내에 삽입되어 상기 용접플랜지(1)를 매개로 일체로 취부되어 후방차체를 보강시킴에 따라 자동차의 후방충돌시에 차체가 충격을 받아 변형될 때에 변형정도를 줄여줄 수 있게 된다.The reinforcement panel according to the present invention having the above-described structure is to increase the structural rigidity by the reinforcement bead (4), the reinforcement panel is inserted into the channel of the rear vehicle body integrated through the welding flange (1) As it is attached to the rear body to reinforce the rear body of the car when the impact is deformed when the vehicle body is impacted and deformed can be reduced.
이상 설명한 바와 같이 본 발명에 따른 자동차의 후방차체 보강판넬구조에 의하면, 후방차체에 결합되어 후방차체의 구조적인 강성을 증대시켜 자동차의 후방충돌시에 차체의 손상정도를 줄여줄 수 있는 효과가 있다.As described above, according to the rear body reinforcement panel structure of the vehicle according to the present invention, it is coupled to the rear body to increase the structural rigidity of the rear body has the effect of reducing the degree of damage to the vehicle body during the rear collision of the vehicle. .
