Abstract

PURPOSE: Reinforcing structure of a rear door for a vehicle is provided to absorb impact of the rear door efficiently, and to protect passengers safely by installing a connecting and fixing bracket between an upper impact bar and a lower impact bar. CONSTITUTION: Upper and lower impact bars(3a,3b) are installed horizontally by installation brackets(2a,2b), and embedded between an inner panel and an outer panel of a door(1). A fixing bracket(4) is mounted between the upper impact bar and the lower impact bar. Upper and lower impact bars are connected by the fixing bracket. The rigidity of the door is improved with installing the fixing bracket between upper and lower impact bars. Deformation of the door is reduced, and passengers are protected by absorbing impact efficiently at a collision.

Description

승용차용 리어도어의 보강구조{Reinforcement Structure of Rear Door for Vehicles}Reinforcement Structure of Rear Door for Vehicles}

본 발명은 승용차용 리어도어의 보강구조에 관한 것으로, 특히 차량의 정면 및 충돌에 대한 보강성 향상과 리어도어 중앙부의 장강성을 향상시키어 탑승객의 안전을 보다 강화시킨 승용차용 리어도어의 보강구조에 관한 것이다.The present invention relates to a reinforcement structure of a rear door for a passenger car, and more particularly, to a reinforcement structure of a rear door for a passenger car, which improves the reinforcement against front and collision of the vehicle and improves the stiffness at the center of the rear door, thereby further enhancing the safety of the passengers. It is about.

주지된 바와 같이 승용차용 전후도어의 왼쪽과 바깥쪽 판넬 사이에는 차량의 정면 및 측면 충돌시 운전자와 탑승객들을 보호하기 위하여 충격흡수성능을 강화시킨 임팩트바(Impact Bar)가 도어를 가로질러 설치되어 있다.As is well known, there is an impact bar across the door between the left and the outer panels of the front and rear doors for passenger cars to protect the driver and passengers in front and side collision of the vehicle. .

이러한 충격흡수성능을 강화시킨 임팩트바는 주로 도어의 차체 방향을 따라1~2개가 내장 설치되는 바, 여기서 종래 리어도어에 설치되는 임팩트바는 도어 하측내부에 2개의 임팩트바가 서로 이격되어 설치되어 있었다.The impact bars for strengthening the shock absorbing performance are mainly installed one to two along the direction of the body of the door, where the conventional impact bars installed in the rear door are two impact bars spaced apart from each other inside the lower door. .

이러 이격된 임팩트바의 설치구조는 기존 차량의 정면 및 측면 충돌시 가해지는 충격에너지를 효과적으로 흡수할 수 없을 뿐만 아니라 가해지는 충격에 의해 도어변형이 크게 작용하여 탑승객의 상해치를 증가시키는 문제점이 있었다.The installation structure of the impact bars spaced apart from each other can not effectively absorb the impact energy applied to the front and side impact of the existing vehicle, and also has a problem of increasing the injury value of the passengers due to the large deformation of the door.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 차량의 정면 및 측면충돌에 대하여 탑승객의 안전을 향상시키면서 도어 중앙부의 장강성도 향상시킨 승용차용 리어도어의 보강구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above conventional problems, to provide a reinforcement structure of a rear door for a passenger car which also improves the stiffness of the center of the door while improving the safety of the passengers against the front and side collision of the vehicle. There is this.

1 : 도어2a,2b : 설치 브라켓트1: Doors 2a, 2b: Mounting Bracket

3a,3b : 임팩트바4 : 연결고정용 브라켓트3a, 3b: impact bar 4: bracket for fixing the connection

상기와 같은 목적을 달성하기 위한 본 발명을 도어의 안쪽과 바깥쪽 판넬 사이에 내장되어 차체 길이 방향을 따라 설치 브라켓트들을 매개로 2개의 상하부임팩트바들이 설치되어 이루어진 승용차용 리어도어에 있어서, 상기 상하부 임팩트바 사이에는 연결 고정용 브라켓트가 설치되어 이루어진 구조로 되어 있다.In the rear door for a passenger car provided with two upper and lower impact bars are installed between the inner and outer panels of the door and the mounting brackets along the vehicle body length direction to achieve the above object, the upper and lower parts Between the impact bar is a structure consisting of a bracket for fixing the connection.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 보강구조를 갖춘 리어도어의 안쪽 판넬을 개방시키어 나타낸 도면이고, 도 2는 본 발명의 요부인 보강구조의 정면도이다.1 is a view showing the inner panel of the rear door having a reinforcing structure according to the present invention open, Figure 2 is a front view of the reinforcing structure that is the main part of the present invention.

본 발명은 도면에 도시된 바와 같이 도어(1)의 안쪽과 바깥쪽 판넬사이에 내장되어 차체 길이방향을 따라 설치 브라켓트(2a,2b)들을 매개로 2개의 상하부 임팩트바(3a,3b)들이 설치되어 이루어진 승용차용 리어도어에 있어서, 상기 상하부 임팩트바(3a,3b)사이에는 연결 고정용 브라켓트(4)가 설치되어 있다.According to the present invention, two upper and lower impact bars 3a and 3b are installed between the inner and outer panels of the door 1 through the mounting brackets 2a and 2b along the longitudinal direction of the vehicle body. In the rear door for a passenger car, a connection fixing bracket 4 is provided between the upper and lower impact bars 3a and 3b.

여기서 상기 도어(1)의 내부에 설치되는 상부 임팩트바(3a)와 하부임팩트바(3b)는 종래와 같이 이격되어 설치되되, 상부 임팩트바(3a)는 대략 수평 방향이나 하부 임팩트바(3b)는 수평방향과 비교할 때 상방향으로 경사져 설치되어 있으면서 각각의 설치 브라켓트(2a,2b)들을 매개로 부착되어 있다.Here, the upper impact bar 3a and the lower impact bar 3b, which are installed inside the door 1, are spaced apart as in the prior art, and the upper impact bar 3a is approximately horizontal or lower impact bar 3b. Is installed inclined upward in comparison with the horizontal direction, and is attached via the respective mounting brackets 2a and 2b.

이렇게 이격 배치된 상하부 임팩트바(3a,3b)사이에는 연결 고정용 브라켓트(4)가 설치되어 이들 사이를 연결 고정한다.The connection fixing bracket 4 is installed between the upper and lower impact bars 3a and 3b spaced apart from each other, thereby fixing the connection therebetween.

이와 같이 상기 상하부 임팩트바(3a,3b)사이에 설치된 연결 고정용 브라켓트(4)에 의하여 도어(1)의 전체 강성이 강화됨에 따라 차량의 정면 및 측면충돌시 가해지는 충격에너지를 보다 효율적으로 흡수하여 도어의 변형을 감소시키어 탑승객의 상해치를 저감시킬 수 있다.As the overall rigidity of the door 1 is strengthened by the connection fixing bracket 4 installed between the upper and lower impact bars 3a and 3b, the impact energy applied during the front and side collision of the vehicle is more efficiently absorbed. This can reduce the deformation of the door to reduce the passenger injury.

상기와 같이 본 발명에 따른 승용차용 리어도어의 보강구조는 도어에 내장 설치되는 상하부 임팩트바들을 연결 고정용 브라켓트로 일체로 연결시킴에 따라 충격강성성능이 향상되는 잇점을 갖추게 된다.As described above, the reinforcement structure of the rear door for a passenger car according to the present invention has an advantage that the impact stiffness performance is improved by integrally connecting the upper and lower impact bars installed in the door with a connection fixing bracket.
