본 발명은 승용차의 측면충돌시 차체의 변형을 줄여 인체의 상해치를 줄이기 위한 승용차의 리어 도어 임팩트빔에 관한 것으로, 더 상세히는 빔의 후단을 리어 도어의 강한 부위에 고정시킴으로써 승용차의 측면충돌시 차체의 침입량을 줄여 승객을 보호할 수 있도록 하는 승용차의 리어 도어 임팩트빔 관한 것이다.The present invention relates to a rear door impact beam of a passenger car to reduce the deformation of the vehicle body in the event of a side collision of the passenger car, and more particularly, to fix the rear end of the beam to a strong part of the rear door, It relates to a rear door impact beam of a passenger car to reduce the amount of intrusion to protect passengers.

제1도는 종래의 도어 임팩트빔을 보인 승용차의 측면도이도, 제2도는 제1도의 A-A선 단면 확대도이다.1 is a side view of a passenger car showing a conventional door impact beam, and FIG. 2 is an enlarged cross-sectional view along the line A-A of FIG.

통상적으로 승용차의 프론트 도어 및 리어 도어(10) 내부에는 차량의 측면충돌시 탑승자의 상해치를 줄이기 위하여 대개 하나의 빔(A)이 용접이나 볼팅에 의하여 설치되고 있다.Typically, one beam (A) is usually installed in the front door and the rear door 10 of a passenger car by welding or bolting in order to reduce the injury value of the occupant during the side collision of the vehicle.

제1도 및 제2도에 도시한 바와같이, 종래에 이러한 빔(A)은 리어 도어(10) 내부에 수평으로 배치되고 있는 바, 빔(A)의 후단이 리어 휠하우스(REAR WHEEL HOUSE; 1)와 중첩되는 위치에 고정되어 있다. 미설명 부호 2는 뒷바퀴이다.As shown in FIG. 1 and FIG. 2, the beam A is conventionally arranged horizontally inside the rear door 10, and the rear end of the beam A is rear wheel house; It is fixed at the position overlapping with 1). Reference numeral 2 is the rear wheel.

그런데, 이러한 종래에 리어 도어(10)에 적용된 임팩트빔은 빔(A)의 후단이 차체 중 약한 부분인 리어 휠하우스(1)에 중첩되는 위치에 고정되어 있으므로 자동차의 측면충돌시 충격력을 효과적으로 흡수하지 못하였다. 따라서 자동차 사고발생시 차체의 변형량이 커짐은 물론 탑승자의 상해치가 높게 나타나는 문제점이 있었다.However, since the impact beam applied to the rear door 10 is fixed at a position where the rear end of the beam A overlaps with the rear wheel house 1, which is a weak part of the vehicle body, the impact beam is effectively absorbed in the event of a side collision of the vehicle. I couldn't. Therefore, when the car accident occurs, the deformation amount of the vehicle body is increased, as well as the injury value of the occupant is high.

본 발명의 목적은 승용차의 리어 도어에 적용되는 임팩트빔의 설치시 빔의 후단을 차체의 강한 부위와 중첩되도록 위치시켜 차량의 측면충돌 사고시 차체의 번형량을 줄이고 탑승자를 보호할 수 있도록 하는데 있다.An object of the present invention is to position the rear end of the beam to overlap the strong portion of the vehicle body when installing the impact beam applied to the rear door of the passenger car to reduce the amount of propagation of the vehicle body in the event of a side collision of the vehicle and to protect the occupants.

이러한 목적을 달성하기 위하여, 본 발명은 차체의 강한 부위인 사이드 실 패널(SIDE SILL PANEL)과 중첩되는 위치에 고정될 수 있도록 빔의 후단을 적당히 기울여 설치한 승용차의 리어 도어 임팩트빔을 제공한다.In order to achieve this object, the present invention provides a rear door impact beam of a passenger car in which the rear end of the beam is properly inclined so as to be fixed at a position overlapping the side seal panel, which is a strong part of the vehicle body.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하며, 종래와 동일한 부분에 대해서는 동일한 부호를 부여하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals will be used to designate like parts.

제3도는 본 발명에 따른 리어 도어 임팩트빔을 보인 승용차의 측면도이고, 제4도는 제3도의 B-B선 단면도이며, 제5도는 제4도의 C-C선 단면도이다.3 is a side view of a passenger car showing a rear door impact beam according to the present invention, FIG. 4 is a sectional view taken along the line B-B of FIG. 3, and FIG. 5 is a sectional view taken along the line C-C of FIG.

본 발명은 리어 도어(10) 내부에 하나의 빔(B)을 설치하여서 된 승용차의 리어 도어 임팩트빔에 있어서, 상기 빔(B)을 경사지게 배치하되, 빔(B)의 후단을 차체의 사이드 실 패널(20)과 중첩되는 위치에 고정시키며, 상기 빔(B)의 후단과 대응되는 위치가 되도록 차체의 사이드 아우터 패널(30)과 상기 사이드 실 패널(20) 사이에 레인퍼스먼트 패널(50)을 더 부착시킨 것에 특징이 있다.According to the present invention, in the rear door impact beam of a passenger car provided with one beam (B) inside the rear door (10), the beam (B) is disposed inclined, and the rear end of the beam (B) is a side seal of the vehicle body. An anchor panel 50 is fixed between the side outer panel 30 of the vehicle body and the side seal panel 20 so as to be fixed to a position overlapping with the panel 20 and to correspond to a rear end of the beam B. It is characterized by further attached.

본 발명에 따르면, 리어 도어(10) 내부에 설치되는 빔(B)을 경사지게 배치하였으며, 이때 임팩트빔에 가해진 충격력 차체의 강한 부위에 전달하기 위하여 빔(B)의 후단을 길게 연장하여 사이드 실 패널(20)에 고정시켰다. 그리고 사이드 실 패널(20)에 전달된 충격력을 리어 플로어 패널(40)에 전달되도록 하기 위하여 가해진 사이드 실 패널(20)과 사이드 아우터 패널(30)간에 레인퍼스먼트 패널(50)을 추가로 설치하였다. 이 레인퍼스먼트 패널(50)은 사이드 실 패널(20)의 변형을 줄이는 역할과 리어 플로어 패널(40)로 충격력을 전달하는 역할을 담당할 수 있도록 하는 것이다.According to the present invention, the beam B installed inside the rear door 10 is inclined, and at this time, the rear end of the beam B is elongated so as to be transmitted to a strong part of the impact body applied to the impact beam, and thus the side seal panel. Fixed at 20. In addition, an anchorage panel 50 is additionally installed between the side seal panel 20 and the side outer panel 30 that are applied to transmit the impact force transmitted to the side seal panel 20 to the rear floor panel 40. . The peripheral panel 50 serves to reduce the deformation of the side seal panel 20 and to transmit the impact force to the rear floor panel 40.

이러한 구조로 된 본 발명은 측면충돌시 충돌부위가 승용차의 리어 도어(10)일때, 빔(B)에 가해진 충격력이 차체의 강한 부위인 사이드 실 패널(20)에 전달되는 한편, 레인퍼스먼트 패널(50)을 통하여 리어 플로어 패널(40)로 전달되므로 충력량을 많이 흡수하여 차체의 변형을 줄임은 물론 충돌시 침입량을 줄여 주게 된다.According to the present invention having such a structure, when the collision site is a rear door 10 of a car during side collision, the impact force applied to the beam B is transmitted to the side seal panel 20, which is a strong part of the vehicle body, while the anchor panel Since it is transmitted to the rear floor panel 40 through 50, it absorbs a large amount of impulse to reduce the deformation of the vehicle body as well as to reduce the amount of intrusion during the collision.

상술한 바와같이, 본 발명은 승용차의 측면충돌시 차체의 침입량을 줄여 탑승자를 보호할 수 있도록 한 것으로, 차량사고에 따른 승용차의 안전도 향상에 기여하는 효과가 있다.As described above, the present invention is to protect the occupants by reducing the intrusion amount of the vehicle body in the event of a side collision of the car, there is an effect that contributes to improving the safety of the passenger car according to the vehicle accident.
