본 발명은 자동화의 좌우양측에 설치되는 도어의 보강구조에 관한 것으로서, 특히 도어의 충돌강성을 향강시켜 도어가 차실로 유입되는 것을 억제 하도록 하는 도어의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a door installed on both the left and right sides of the automation, and more particularly, to a reinforcing structure of the door to enhance the collision stiffness of the door to prevent the door from entering the vehicle compartment.

일반적으로 자동차의 측면부 차체구조는 제1도에 도시하고 있는 바와 같이, 전면기둥(1 : front pillar)과 중심기둥(2 : center pillar) 및 후면기둥(3 : rear pillar) 사이에 개구부가 형성되고, 상기 개구부에는 도어(10)가 개폐 가능하게 설치되며, 상기 기둥(1)(2)(3)들 상단부에 지붕의 외측부를 형성하는 루프레일(4 : roof rall)이 연결되며, 상기기둥(1)(2)(3)들 하단부에 차량의 저면부를 형성하는 플로어판넬(floor panel)과 사이드실(side sill)이 연결되어 있다.In general, as shown in FIG. 1, the vehicle body structure of the side part of an automobile includes an opening formed between a front pillar (1) and a center pillar (2) and a rear pillar (3: rear pillar). The door 10 is installed to be opened and closed at the opening, and a roof rail 4 to form an outer portion of the roof is connected to an upper end of the pillars 1, 2, and 3. 1) The floor panel and side sill, which form the bottom of the vehicle, are connected to the lower end of the (2) and (3).

여기에서 종래 도어의 보강구조는. 제2도에 도시하고 있는 바와 같이, 외측판넬(11)과 내측판넬(12)이 절곡되어 소정의 공간을 형성하는 도어(10)의 내측 공간부에 창문(20)이 슬라이드 가능하게 설치되고, 상기 창문(20)이 설치된 공간부의 일측부에는 임팩드바(30)의 좌우 양단부가 정션에 의해 외측판넬(11) 내측면에 설치되어 있다.Here, the reinforcement structure of the conventional door is. As shown in FIG. 2, the window 20 is slidably installed in the inner space of the door 10 in which the outer panel 11 and the inner panel 12 are bent to form a predetermined space. One side portion of the space portion in which the window 20 is installed is provided on the inner side of the outer panel 11 by the junction with the left and right ends of the impact bar 30.

이와 같이 구성되는 종래 도어의 보강구조는, 차량의 측면부 충돌과 같은 사고로 도어(10)에 충격이 가해지는 경우, 임팩드바(30)가 충격에너지를 흡수하도록 함은 물론, 충격에 의해 외측판넬(11)이 파손된 경우에도 도어(10)의 외측판넬(11)이 차실로 유입되는 것을 억제하여 차실에 탑승한 승원이 부상당하는 것을 억제 하도록 되어있다.The conventional reinforcement structure of the door configured as described above allows the impact bar 30 to absorb the impact energy when the impact is applied to the door 10 due to an accident such as a side collision of the vehicle. Even if (11) is broken, the outer panel 11 of the door 10 is prevented from flowing into the vehicle compartment, thereby preventing the occupant of the cabin from being injured.

그러나 이러한 종래 도어의 보강구도는 도어(10)와 임팩드바(30)에 의해 충격에너지를 흡수하는 기능이 미흡하여, 일정이상의 충격 하중이 도어(10)에 가해지는 경우, 도어(10)의 파손이 심하고, 변형된 도어(10)가 실내쪽을 침입하여, 차실에 탑승한 승원의 안전이 위협되었다. 이로인해, 차체의 변형을 효율적으로 억제하고, 충격을 완충할수 있는 구조가 요구 되었다.However, such a reinforcement structure of the conventional door is insufficient in the function of absorbing the impact energy by the door 10 and the impact bar 30, the damage of the door 10 when a predetermined or more impact load is applied to the door 10 This severe, deformed door 10 broke into the interior, threatening the safety of the occupant in the cabin. As a result, there is a demand for a structure that can effectively suppress deformation of the vehicle body and cushion shocks.

본 발명의 목적은, 상기 종래와 같은 문제점과 요구조건을 충족하기 위해, 외측판넬의 외측면 하단부에 프로턱터를 설치하고, 상기 외측판넬과 내측판넬이 절곡되어 소정의 공간을 형성하는 도어의 내측 공간부 하단부에 외측면이 절곡되어 형성되며, 내부에 수납흠이 형성된 패드를 설치하여, 도어에 충격이 가해지는 경우에도, 상기 도어의 변형을 효과적으로 억제하여, 차내에 탑승한 승원이 부상당하는 것을 억제 하도록 하는 도어의 보강구조를 제공 하는데 있다.An object of the present invention, in order to meet the same problems and requirements as in the prior art, to install a protruder on the lower end of the outer surface of the outer panel, the outer panel and the inner panel is bent to form a predetermined space inside the door The outer surface is bent at the lower end of the space portion, and a pad with a storage flaw is formed therein, so that even when an impact is applied to the door, the deformation of the door is effectively suppressed, and the occupant in the vehicle is injured. It is to provide a reinforcement structure of the door to be suppressed.

이하, 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.

본 발명의 도어의 보강구조도, 제3도에 도시하고 있는 바와 같이, 외측판넬(11)과 내측판넬(12)이 절곡되어 소정의 공간을 형성하는 도어(10)의 내측 공간부에 임팩드바(30)의 좌우 양단부가 정션에 의해 외측판넬(11) 내측면에 설치되어 지는 것은 종래와 같다. 단, 본 발명은, 상기 외측판넬(11)의 외측면 하단부에 프로텍터(50)를 설치하고, 상기 외측판넬(11)과 내측판넬(12)이 절곡되어 소정의 공간을 형성하는 도어(10)의 내측 공간 하단부에 외측면이 절곡되어 형성되며, 내부에 수납흠(45)이 형성된 패드(40)가 설치됨을 그 기술적 구성상 기본 특징으로 한다.As shown in FIG. 3, the reinforcing structure of the door of the present invention is an impact bar in the inner space of the door 10 in which the outer panel 11 and the inner panel 12 are bent to form a predetermined space. The left and right ends of the 30 are provided on the inner side of the outer panel 11 by the junction as in the prior art. However, in the present invention, the protector 50 is provided at the lower end of the outer surface of the outer panel 11, the outer panel 11 and the inner panel 12 is bent to form a predetermined space (10) The outer surface is formed by bending the outer surface of the lower end of the inner space, and the pad 40 is formed in the receiving flaw 45 therein is characterized in its technical configuration.

이와 같이 구성되는 도어의 보강구조는 도어(10)에 충격이 가해지는 경우, 외측판넬(11)의 외측면에 취부된 프로텍터(50)에 의해 1차적인 충격에너지를 흡수하고, 도어(10)의 공간부에 외측면이 내측판넬(12)과 외측판넬(11)에 접하며 설치된 패드에 의해 2차적인 충격에너지가 흡수되어, 상기 도어(10)가 충격에 의하여 파손 및 변형을 효과적으로 억제하여, 차내에 탑승한 승원이 부상당하는 것을 억제 하도록 한다.The reinforcing structure of the door configured as described above absorbs primary impact energy by the protector 50 mounted on the outer surface of the outer panel 11 when the impact is applied to the door 10, and the door 10. Secondary impact energy is absorbed by a pad provided with the outer surface of the space portion in contact with the inner panel 12 and the outer panel 11 so that the door 10 is effectively restrained from damage and deformation due to the impact, Control the occupants in the vehicle from getting injured.

따라서, 이러한 본 발명은, 차량의 좌우양측에 장착되어진 도어(10)에 측면충돌사고가 발생하여 충격이 가해지는 경우에도, 충격에너지를 효과적으로 흡수하여, 상기 도어(10)의 변형을 효과적으로 억제하고, 차내에 탑승한 승원이 부상당하는 것을 억제 하도록 하는 효과가 있다.Therefore, the present invention effectively absorbs the impact energy even when a side collision accident occurs in the door 10 mounted on the left and right sides of the vehicle, and thus suppresses deformation of the door 10 effectively. In addition, it is effective to suppress the injuries of the occupants in the vehicle.

이상에서 살펴본 바와 같이 도어에 충격이 가해지는 경우에도, 도어의 외측면에 취부된 프로텍터와 도어의 공간부에 설치된 패드에 의하여 충격에너지를 효과적으로 흡수하여, 도어의 변형을 효과적으로 억제하고, 차내에 탑승한 승원이 부상당하는 것을 억제 하도록 하는 매우 유용한 발명인 것이다.As described above, even when an impact is applied to the door, the protector mounted on the outer surface of the door and the pad provided in the space of the door effectively absorb the impact energy, thereby effectively suppressing the deformation of the door and riding in the vehicle. It is a very useful invention that allows an occupant to be injured.
