Abstract

본 발명은 자동차용 도어의 보강구조에 관한 것으로서, 다단으로 절곡된 내측판넬(11)의 일측면에 정션브라켓(30)의 일측에 형성된 취부부(31)가 취부되고, 상기 정션브라켓(30)의 타측단부 결합부(32)에는 원통형의 임팩트바(20)가 취부되며, 임팩트바(20)가 취부된 내측판넬(11)의 일측 절곡부는 팬더(50)에 착탈 가능하게 형성되어 지는 것은 종래와 같다. 단, 본 발명은 상기 정션브라켓(30)의 취부부(31)와 결합부(32) 저면이 내측판넬(11)의 절곡부 내측면에 접하여 취부되어, 차량을 운행중 충돌사고등에 의하여 도어(10)에 충격이 가해지는 경우, 상기 도어(10)의 공간부에 설치되는 임팩트바(20)로 충격에너지가 전달되고, 상기 임팩트바(20)로 전달된 충격에너지는 정션브라켓(30)으로 전달되며, 상기 정션브라켓(30)으로 전달된 충격에너지는 기둥 및 팬더(50)로 분사시켜 주게된다. 이로인해 도어(10) 및 측부 차체가 측면충돌과 같은 사고에 의하여 도어(10)에 충격이 가해지는 경우에도 도어(10)가 차실로 침입되는 것을 효과적으로 억제시켜 주도록 하는 자동차용 도어의 보강구조 이다.The present invention relates to a reinforcing structure of a door for an automobile, and the mounting portion 31 formed on one side of the junction bracket 30 is mounted on one side of the inner panel 11 bent in multiple stages, and the junction bracket 30 is mounted. Cylindrical impact bar 20 is attached to the other end of the coupling portion 32, one side bent portion of the inner panel 11, the impact bar 20 is mounted is detachably formed on the pandas 50 Same as However, in the present invention, the bottom of the mounting portion 31 and the coupling portion 32 of the junction bracket 30 is in contact with the inner surface of the bent portion of the inner panel 11, the door 10 by a collision accident, etc. while driving the vehicle When an impact is applied to the impact bar, impact energy is transmitted to the impact bar 20 installed in the space of the door 10, and the impact energy transmitted to the impact bar 20 is transferred to the junction bracket 30. The impact energy delivered to the junction bracket 30 is sprayed to the pillars and the pandas 50. This is a reinforcement structure of an automobile door that effectively suppresses the door 10 from entering the vehicle even when the door 10 and the side body are impacted to the door 10 due to an accident such as a side collision. .
