본 발명은 차량의 도어에 관한 것으로, 특히 도어의 내측 패널과 외측 패널의 접합부에 구조적인 강성을 증대시키는 보강브라켓이 부착된 차량의 도어 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door of a vehicle, and more particularly to a door reinforcing structure of a vehicle having a reinforcing bracket for increasing structural rigidity at a junction of an inner panel and an outer panel of the door.

종래 승용차량의 차체구조에서 전방 충돌사고 발생시에 도 1에서 화살표로 도시한 바와 같이 충격에너지가 프론트 사이드멤버(1)를 통해 카울 결합부(2)에 전 달되고, 상기 카울 결합부에 전달된 충격에너지는 프론트 필러(3)의 상부와 하부로 각각 분산되어 전달됨과 더불어 도어의 아웃터 벨트(4)를 통해 도어로 전달되게 된다.In the case of a front collision accident in a vehicle structure of a conventional passenger vehicle, impact energy is transmitted to the cowl coupling portion 2 through the front side member 1 and transmitted to the cowl coupling portion as shown by arrows in FIG. 1. The impact energy is distributed to the upper and lower portions of the front pillar 3 and transmitted to the door through the outer belt 4 of the door.

또한 도 1에서 상기 카울 결합부(2)의 구체적인 단면으로 도시한 바와 같이, 차체의 내측으로 위치된 사이드 아웃터 패널(5)에 보강패널(6)이 부착되어 구조적인 강성이 보강되고, 상기 사이드 아웃터 패널(5)의 외측에는 도어를 형성하는 도어 내측패널(7)이 배치되며, 상기 도어 내측패널(7)에는 도어 외측패널(8)이 부착되어 도어를 형성하게 된다.In addition, as shown in a specific cross section of the cowl coupling portion 2 in FIG. 1, a reinforcement panel 6 is attached to a side outer panel 5 positioned inwardly of the vehicle body to reinforce structural rigidity, and the side A door inner panel 7 forming a door is disposed outside the outer panel 5, and a door outer panel 8 is attached to the door inner panel 7 to form a door.

그리고 상기 도어 내측패널(7)에는 도어의 폭방향을 따라 연장되게 형성된 상기 아웃터 벨트(4)의 선단부가 부착되고, 상기 도어 외측패널(8)의 전방에는 팬더패널(9)이 배치되어 있다.And the front end part of the outer belt 4 formed so that it may extend along the width direction of the door may be attached to the said door inner panel 7, The panda panel 9 is arrange | positioned in front of the said door outer panel 8.

그런데 상기와 같이 종래에 카울 결합부의 도어 아웃터 벨트 앞부분에서 사이드 아웃터 패널과 도어 내측패널이 단차지게 절곡된 구조에서는 강성이 취약해져 차량의 전방 충돌사고 발생시에 프론트 필러가 과도하게 변형되면서 충돌 대응성능이 미흡하다고 하는 결점이 있었다.However, in the structure in which the side outer panel and the door inner panel are stepped bent at the front part of the door outer belt of the cowl coupling part as described above, the rigidity is weak and the front pillar is excessively deformed in the event of a front collision of the vehicle. There was a shortcoming.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 사이드 아웃터 패널과 도어 내측패널 및 도어 외측패널이 접하는 도어의 전방 선단부에 보강브라켓을 추가하여 구조적인 강성을 증대시켜서 차량의 전방 충돌사고 발생시에 차체의 과도한 변형을 억제하여 탑승자를 보다 안전하게 보호할 수 있도록 한 차량의 도어보강 구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described circumstances, and a reinforcing bracket is added to the front end portion of the door where the side outer panel and the door inner panel and the door outer panel contact each other to increase structural rigidity, thereby causing a front collision of the vehicle. It is an object of the present invention to provide a door reinforcement structure of a vehicle to suppress excessive deformation of the vehicle body to protect the occupant more safely.

상기와 같은 목적을 달성하기 위한 본 발명은, 도어 아웃터 벨트가 도어 내측패널과 도어 외측패널의 접합부까지 연장되어 일체로 용접되고, 상기 도어 아웃터 벨트와 도어 내측패널 사이의 전방단부에 ㄷ자 형상의 단면을 가진 보강브라켓이 용접되되, 상기 보강브라켓의 내측플랜지와 전면부는 상기 도어 내측패널의 절곡부에 용접되고 외측플랜지는 상기 도어 아웃터 벨트에 용접된 것을 특징으로 한다.According to the present invention for achieving the above object, the door outer belt extends to the junction of the door inner panel and the door outer panel to be integrally welded, the cross-section of the U-shape at the front end between the door outer belt and the door inner panel Reinforcement bracket having a welded, the inner flange and the front portion of the reinforcing bracket is welded to the bent portion of the door inner panel and the outer flange is characterized in that the welded to the door outer belt.

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

도 2에는 본 발명에 따른 차량의 도어보강구조의 구체적인 단면이 도시되어 있는 바, 즉 도어를 기준으로 차체의 내측 및 전방에 위치되는 사이드 아웃터 패널(5)이 도어의 전방 선단부와 인접한 부위에서 차체의 내측으로 다단계로 절곡되어 형성되고, 상기 사이드 아웃터 패널(5)과 인접해서 도어 내측패널(7)이 차체의 내측으로 배치되며, 상기 도어 내측패널(7)에 도어 외측패널(8)이 부착되어 도어를 형성하는 한편, 상기 도어 외측패널(8)의 전방으로 팬더패널(9)이 배치된 구성에서는 종래와 동일하게 되어 있다.Figure 2 shows a specific cross-section of the door reinforcement structure of the vehicle according to the present invention, that is, the side outer panel (5) located on the inside and front of the vehicle relative to the door in the area adjacent to the front front end of the door It is formed by bending in multiple stages of the inner side, the door inner panel (7) is disposed inside the vehicle body adjacent to the side outer panel (5), the door outer panel (8) is attached to the door inner panel (7) In the configuration in which the panda panel 9 is disposed in front of the door outer panel 8, the door is formed in the same manner as before.

본 발명에서는 상기 사이드 아웃 패널이 차체의 내측으로 절곡된 부위에서 도어 내측패널(7)과 도어 외측패널(8)이 접합되어 도어의 전방 선단부를 형성하는 부분에 구조적인 강성을 보강하도록 대체로 ㄷ자 형상의 단면을 가진 보강브라켓(10)이 도어 내측패널(7)에 용접되고, 도어 아웃터 벨트(4)의 선단부는 차체의 전방으로 더 연장되어서 상기 도어 내측패널(7)과 도어 외측패널(8)의 사이에 용접되며, 상기 보강브라켓(10)은 상기 도어 아웃터 벨트(4)와도 일체로 용접되게 된다.In the present invention, the side-out panel is generally c-shaped so as to reinforce structural rigidity in a portion where the door inner panel 7 and the door outer panel 8 are joined to form a front tip of the door at a portion where the side out panel is bent into the inside of the vehicle body. A reinforcing bracket 10 having a cross section of is welded to the door inner panel 7, and the front end of the door outer belt 4 extends further to the front of the vehicle body so that the door inner panel 7 and the door outer panel 8 are extended. Between the welds, the reinforcement bracket 10 is also welded integrally with the door outer belt (4).

즉 상기 보강브라켓(10)은 그 내측플랜지와 전면부가 상기 도어 내측패널(7)의 전방 절곡부에 용접됨과 더불어 그 외측플랜지가 상기 도어 아웃터 벨트(4)에 용접되어, 도어 내측패널(7)과 보강브라켓(10) 및 도어 아웃터 벨트(4)가 일체로 접합되어 구조적인 강성이 증대되고, 또한 상기 도어 아웃터 벨트(4)의 선단부가 도어 내측패널(7)과 도어 외측패널(8)의 접합부까지 연장되어서 일체로 용접됨으로써, 도어의 전방단부의 강성이 한층 강화되게 되는 것이다.That is, the reinforcing bracket 10 has its inner flange and front face welded to the front bent portion of the door inner panel 7, and its outer flange is welded to the door outer belt 4, so that the door inner panel 7 And the reinforcing bracket 10 and the door outer belt 4 are integrally bonded to each other to increase structural rigidity, and the front end portions of the door outer belt 4 are formed of the door inner panel 7 and the door outer panel 8. By extending to the joint and welding together, the rigidity of the front end of the door is further enhanced.

상기와 같이 카울 결합부위의 도어 전방 선단부의 구조적인 강성이 현저히 증가됨으로 인해 차량의 전방 충돌사고 발생시에 충격에너지가 전달되어도 과도한 변형을 유발하지 않고 차체의 후방으로 적절히 전달하여 분산시킴으로써, 탑승자를 보다 안전하게 보호할 수 있게 되는 것이다.As the structural rigidity of the door front end of the cowl coupling portion is significantly increased as described above, even when the impact energy is transmitted in the event of a forward collision of the vehicle, the vehicle is properly transmitted and distributed to the rear of the vehicle body without causing excessive deformation. It will be safe to protect.

이상 설명한 바와 같이 본 발명에 따른 차량의 도어보강구조에 의하면, 카울 결합부위의 도어 전방 선단부에 보강브라켓을 부착하여 도어 내측패널과 도어 아웃터 벨트의 접합 강성을 증대시킴과 더불어 도어 내측패널과 도어 외측패널이 접하는 부분까지 도어 아웃터 벨트를 연장시켜 일체로 접합하여 도어의 구조적인 강성을 증대시킴으로써, 차량의 전방 충돌사고 발생시에 프론트 필러와 도어의 과도한 변형을 억제하면서 충격에너지를 차체의 후방으로 적절히 전달하여 분산시킴으로써 탑승자를 보다 안전하게 보호할 수 있을 뿐만 아니라 진동 및 소음도 줄여서 승차 감도 향상시키는 등의 효과가 있다.As described above, according to the door reinforcement structure of the vehicle according to the present invention, the reinforcing bracket is attached to the front end of the door at the cowl coupling part to increase the joint rigidity of the door inner panel and the door outer belt, and the door inner panel and the outer door of the door. By extending the door outer belt to the part where the panel is in contact with the panel and increasing the structural rigidity of the door, the impact energy is properly transferred to the rear of the vehicle body while suppressing excessive deformation of the front pillar and the door in the event of a front collision of the vehicle. By dispersing, not only can the passengers be more safely protected, but also vibration and noise can be reduced, thereby improving ride sensitivity.
