본 발명은 자동차의 좌우양측 후부에 설치되는 리어도어구조에 관한 것으로서, 더욱더 상세하게는 차량의 후부에 개폐가능하게 설치되는 리어도어의 강성을 향상시켜, 차량의 측부 충돌시에도 리어도어의 변형량이 극소화 되도록 함으로서, 차실에 탑승한 승원이 차량을 운행중 발생하는 충돌사고등에 의해 부상당하는 것이 억제되도록 하는 자동차용 리어도어의 보강구조에 관한 것이다.The present invention relates to a rear door structure provided at the rear left and right sides of the vehicle, and more particularly, to improve the rigidity of the rear door that can be opened and closed at the rear of the vehicle, so that the amount of deformation of the rear door in the event of a side collision of the vehicle By minimizing, it relates to a reinforcement structure of a rear door for an automobile so that an occupant in a cabin is prevented from being injured by a collision accident or the like that occurs while driving the vehicle.

일반적으로 자동차의 차체구조는 제 1 도에 도시하고 있는 바와 같이, 전면기둥(10:gront pillar)과 중심기둥(20:center pillar)및 후면기둥(30:rear pillar) 사이에 개구부가 형성되어, 상기 개구부에 전면도어(50)와 리어도어(70)가 개폐 가능하게 설치되고, 상기 기둥들 상단부에 지붕(40)의 외측부를 형성하는 루프레일(roof rail)이 연결되며, 상기 기둥을 하단부에 차량(100)의 저면부를 형성하는 프론트판넬(front panel)과 사이드실(60:side sill)이 연결되어 있다.In general, as shown in FIG. 1, an automobile body structure has an opening formed between a front pillar (10: gront pillar), a center pillar (20: center pillar), and a rear pillar (30: rear pillar). The front door 50 and the rear door 70 are installed to be opened and closed at the opening, and a roof rail is formed at an upper end of the pillars to form an outer portion of the roof 40. The front panel which forms the bottom part of the vehicle 100 and the side sills 60 are connected.

여기에서, 종래 자동차용 리어도어의 보강구조는 제 2 도와 제 3도에 도시되는 바와 같이, 다단으로 절곡된 내측판넬(71: INNER PANEL)과 외측판넬(72:OUTER PANEL)이 취부되어 소정의 공간이 형성되고, 상기 공간의 하단부에는 원통형의 임팩트바(91)가 정션브라켓(90)에 의해 취부되는 리어도어(70)의 일측부에 힌지(75)가 설치되고, 상기 리어도어(70)의 타측부에는 록장치(76)가 취부되어 있다.Here, the reinforcing structure of a conventional rear door for a vehicle is as shown in Figs. 2 and 3, the inner panel 71 (inner panel 71) and the outer panel (72: outer panel) bent in multiple stages is attached to a predetermined A space is formed, and at the lower end of the space, a hinge 75 is installed at one side of the rear door 70 in which a cylindrical impact bar 91 is mounted by the junction bracket 90, and the rear door 70 is provided. On the other side of the lock device 76 is mounted.

이와같이 구성되는 종래 자동차용 리어도어의 보강구조는, 리어도어(70)의 내부에 취부되는 임팩트바(91)에 의해, 차량을 운행중 측면충돌 사고등에 의하여 리어도어(70)에 충격이 가해지는 경우 록장치(76)와 힌지(75)가 충격하중을 흡수 및 분산시켜, 측부 구조물인 리어도어(70)가 실내로 칩입되는 것을 억제하여, 실내의 승원이 보호되도록 되어 있다.The conventional reinforcement structure of the rear door for a vehicle configured as described above is a case where an impact bar 91 mounted inside the rear door 70 causes an impact on the rear door 70 due to a side collision accident or the like while the vehicle is in operation. The locking device 76 and the hinge 75 absorb and disperse the impact load, thereby preventing the rear door 70, which is a side structure, from entering the room, thereby protecting the occupant of the room.

그러나, 이러한 종래 자동차용 리어도어의 보강구조는, 리어도어(70)에 일정이상의 충격이 가해지는 경우, 힌지(75)와 록장치(76)에 의해서만 충격에너지의 분산이 이루어지게 됨으로서, 상기 충격에너지가 안정되게 분산되지 못하고, 리어도어(70)가 충격에너지에 의해 실내로 침입하여 차내에 탑승한 승원이 부상을 입게되는 문제점이 있었다.However, such a conventional reinforcement structure for automobile rear doors, when a shock is applied to the rear door 70 by a predetermined or more, the impact energy is dispersed only by the hinge 75 and the lock device 76, the impact The energy was not dispersed stably, and the rear door 70 penetrated into the room by the impact energy, causing the crew to be injured in the car.

본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 사이드프레임의 일측면에 지지부와 체결부가 형성되는 브라켓을 체결하고, 상기 사이드프레임에 접하는 내측판넬에는 요홈부를 형성하여, 측면 충돌등과 같은 사고에 의하여 리어도어에 충격이 가해지는 경우에도 충격에너지를 안정되게 분산시켜, 충격하중에 의하여 리어도어가 차실로 유입되는 것이 억제되도록 하는 자동차용 리어도어의 보강구조를 제공하는 데 있다.An object of the present invention, in order to supplement the conventional problems as described above, fastening the bracket is formed on one side of the side frame with the support portion, and the inner panel in contact with the side frame to form a groove portion, The present invention provides a reinforcement structure of a vehicle rear door that stably distributes impact energy even when an impact is applied to the rear door by the same accident so that the rear door is prevented from entering the vehicle compartment by the impact load.

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

본 발명의 자동차용 리어도어의 보강구조도 제 4 도에 도시되는 바와 같이, 다단으로 절곡형성된 내측판넬(71:INNER PANEL)과 외측판넬(72:OUTER PANEL)이 취부되어 소정의 공간이 형성되고, 상기 공간의 하단부에는 원통형의 임팩트바(91)가 정션브라켓(90)에 의해 취부되는 리어도어(70)에 있어서, 상기 내측판넬(71:INNER PANEL)에 브라켓(110)의 일측에 형성된 지지부(101)가 삽입되는 요흠부(73)를 형성하고, 상기 브라켓(110)의 타측에 형성된 체결부(102)는 사이드프레임(80)의 일측면에 볼트(79)체결됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 4, the reinforcing structure of the rear door for a vehicle of the present invention is provided with a predetermined space formed by mounting an inner panel 71 (inner panel) 71 formed in multiple stages and an outer panel 72 (outer panel). In the rear door 70 in which a cylindrical impact bar 91 is attached to the lower end of the space by the junction bracket 90, a support part formed at one side of the bracket 110 on the inner panel 71: INNER PANEL. The 101 is formed in the recess portion 73 is inserted, and the fastening portion 102 formed on the other side of the bracket 110 is fastened to one side of the side frame 80 bolts 79 in the technical configuration of the basic It features.

이와같이 구성되는 본 발명은, 내측판넬(71:INNER PANEL)과 외측판넬(72:OUTER PANEL)이 소정의 간격을 두고 취부되어 형성되는 공간부에, 양측단부가 휠아치에 취부되는 사이드프레임(80)의 일측면에 체결부(102)가 볼트(79)체결되는 브라켓(110)의 지지부(101)가 내측판넬(71:INNER PANEL)에 형성되는 요흠부(73)를 통하여 내삽되어, 외부의 충격등에 의해 리어도어(70)의 외측판넬(72:OUTER PANEL)에 충격이 가해지는 경우, 내측판넬(71:INNER PANEL)을 통하여 공간부에 삽입되는 지지부(101)가 1차적으로 충격에너지가 흡수되고, 상기 지지부(101)에 의해 흡수하고 남은 충격에너지는 브라켓(110)의 체결부(102)에 의해 2차적으로 흡수되며, 3차적으로 사이드프레임(80)으로 충격에너지를 폭넓게 분산시키게 된다.According to the present invention configured as described above, the side frame 80 having both end portions mounted to the wheel arch is formed in a space formed by mounting the inner panel 71 (INNER PANEL) and the outer panel 72 (OUTER PANEL) at predetermined intervals. The support portion 101 of the bracket 110, to which the fastening portion 102 is fastened to the bolt 79 on one side thereof, is interpolated through the recessed portion 73 formed in the inner panel 71 (inner panel), thereby When an impact is applied to the outer panel 72 of the rear door 70 by an impact lamp, impact energy is primarily applied to the support 101 inserted into the space through the inner panel 71. The impact energy absorbed and absorbed by the support portion 101 is secondarily absorbed by the fastening portion 102 of the bracket 110, and thirdly, the impact energy is widely distributed to the side frame 80. .

이로인해 실내로 전달되는 충격을 완충시켜 주고, 리어도어(70)및 측부차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.This cushions the shock transmitted to the room and effectively suppresses the rear door 70 and the side vehicle body from entering the room.

따라서, 이러한 본 발명은 차량을 운행중 측면충돌사고가 발생하여 차량의 후부에 설치된 리어도어(70) 충격이 가해지는 경우에도, 상기 충격에너지에 의해 리어도어(70)가 변형되는 것이 억제됨은 물론, 충격에너지를 효과적으로 흡수 및 분산시켜 차실에 탑승한 승원의 안전성이 향상되도록 하는 효과가 있다.Therefore, in the present invention, even when a side collision accident occurs while driving a vehicle and the rear door 70 installed at the rear of the vehicle is applied, the rear door 70 is not deformed by the impact energy. Effectively absorbing and dispersing the impact energy has the effect of improving the safety of the occupant in the cabin.

이상에서 살펴본 바와 같이, 본 발명은 리어도어(70)에 충격이 가해지는 경우에도, 충격에너지를 효과적으로 흡수 및 분산시켜, 측면 충돌시에도 차실에 탑승한 승원이 부상당하는 것이 억제되도록 하는 매우 유용한 것이다.As described above, the present invention is very useful for effectively absorbing and dispersing impact energy even when an impact is applied to the rear door 70, so that the occupant in the cabin can be prevented from being injured even during a side collision. .
