충격흡수 수단을 갖춘 차량용 리어도어{An automotive rear door having the impact absorbing means }An automotive rear door having the impact absorbing means}

본 발명은 충격흡수 수단을 갖춘 차량용 리어도어에 관한 것으로, 보다 상세하게는 측면 충격에 의한 도어의 밀림을 저지할 수 있도록 된 충격흡수 수단을 갖춘 차량용 리어도어에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle rear door provided with shock absorbing means, and more particularly to a vehicle rear door equipped with shock absorbing means capable of preventing the door from sliding due to side impact.

일반적으로 차량용 도어는 차량 실내로 승객이 탑승하거나 실외로 나가기 위한 잠금 장치를 매개로 개폐되는 가장 근본적인 기능이외에 외부로부터 가해지는 충격에 대한 완충작용은 물론 글래스의 승하강등을 위한 윈도우레귤레이터등이 내장되도록 다양한 형상의 패널들이 서로 접합되어 결합된 구조로 이루어져 자체적인 하중이 매우 큰 특징을 갖게된다.In general, the door for the vehicle is not only the most basic function of opening and closing through the locking device for passengers to enter or leave the vehicle interior, but also provide a built-in window regulator for shock absorbing from the outside as well as raising and lowering the glass. Panels of various shapes are bonded to each other to form a combined structure has a very large characteristic of its own load.

이와 같은 도어는 통상, 차체의 측면부위의 중간부를 형성하는 B필라(B)를 기준으로 각각 독립적으로 작용하는 프론트(Front)도어와 리어(rear)도어로 나뉘게 되고 이중, 상기 리어도어(D)는 도 1에 도시된 바와 같이 차체의 B필라(B)부위에힌지 고정되고 C필라(C)부위를 이루는 다단계로 절곡된 차체아우터패널(2)부위와 닫힘 시 밀착되게 된다.Such doors are generally divided into front doors and rear doors that independently act on the basis of the B pillars B, which form an intermediate part of the side portion of the vehicle body, of which the rear door D is As shown in FIG. 1, the hinge is fixed to the B pillar (B) portion of the vehicle body and is in close contact with the vehicle body outer panel (2) portion bent in multiple stages forming the C pillar (C) portion.

이에 따라, 상기 리어도어(D)의 닫힘 시 차체아우터패널(2)의 서로 단차진 제1·2·3절곡단(2a,2b,2c)과 상응되는 형상을 이루도록 단차진 밀착부(1a)를 형성한 도어(D)의 도어인너패널(1)이 서로 접촉된 상태를 이루면서 상기 절곡단(2a,2b,2c)의 폭 만큼 형성되는 오버랩구간(L)을 통해 도어(D)에 가해진 충격력(F)에 대해 도어(D)의 실내로의 밀림을 저지하게 된다.Accordingly, when the rear door D is closed, the stepped close contact portion 1a forms a shape corresponding to the stepped first, second, and third bent ends 2a, 2b, and 2c of the car body outer panel 2. Impact force applied to the door D through the overlap section L formed by the width of the bent end (2a, 2b, 2c) while forming a state in which the door inner panel 1 of the door (D) formed the contact with each other With respect to (F), the rolling of the door D to the interior is prevented.

그러나, 이와 같이 도어(D)를 이루는 인너패널(1)의 밀착부(1a)와 차체아우터패널(2)의 제1·3절곡단(2a,2c)에 단차지게 이어진 제2절곡단(2b)이 서로 수평하게 접촉된 상태를 이루는 구조로 되어 만약, 도어(D)에 가해지는 충격력(F)이 상대적으로 크게 되면 상기 밀착부(1a)와 제2절곡단(2b)의 밀착구간이 밀리면서 슬립(Slip)을 발생하는 슬립구간(K)으로 작용되어 충격력(F)에 대한 강성이 약화되는 단점이 있게 된다.However, the second bent end 2b which is stepped to the contact portion 1a of the inner panel 1 forming the door D and the first and third bent ends 2a and 2c of the vehicle body panel 2 as described above. ) Is in a state where the horizontal contact with each other, so that if the impact force (F) applied to the door (D) is relatively large, the close contact between the contact portion (1a) and the second bent end (2b) is closed While acting as a slip section (K) for generating a slip (Slip) there is a disadvantage that the rigidity for the impact force (F) is weakened.

이에 따라, 상기 도어(D)의 인너패널(1)과 차체아우터패널(2)의 오버랩구간(L)을 증가시켜 이와 같은 슬립현상을 방지할 수 있지만 이와 같이, 상기 오버랩구간(L)을 증가시키게 되면 도어(D)내에 장착된 글래스나 레귤레이터등과 같은 장치들의 운동 궤적이 상대적으로 좁아져 특히, 글래스의 승·하강성이 나빠지는 단점이 있게 된다.Accordingly, this overlap phenomenon (L) can be prevented by increasing the overlap section (L) of the inner panel 1 and the vehicle body panel (2) of the door (D), but in this way, the overlap section (L) is increased. In this case, the motion trajectory of devices such as glass or regulator mounted in the door D is relatively narrowed, and in particular, there is a disadvantage in that the lifting and lowering of the glass becomes worse.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 도어가 밀착되는 차체패널부위에 도어의 밀림 시 결합되면서 저지시키는 돌출된 부위를 형성하여 도어와 차체패널사이의 슬립구간의 형성을 근본적으로 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, by forming a protruding portion which is prevented while being coupled when the door is pushed on the body panel portion where the door is in close contact with the door, thereby essentially forming the slip section between the door and the body panel. The purpose is to prevent.

상기와 같은 목적을 달성하기 위한 본 발명은, 차체아우터패널의 서로 단차진 제1·3절곡단을 이어주면서 돌출된 제2절곡단에 길이방향을 따라 소정폭을 갖으면서 갭을 형성하는 스토퍼브라켓트가 구비되는 한편, 상기 차체아우터패널의 제2절곡단부위로 위치되는 도어의 인너패널의 밀착부에 돌출된 스토퍼가 구비되어진 것을 특징으로 한다.The present invention for achieving the above object, the stopper bracket to form a gap while having a predetermined width along the longitudinal direction to the second bent end protruding while connecting the first and third bent ends of the vehicle body panel mutually stepped On the other hand, characterized in that the stopper protruding from the close contact portion of the inner panel of the door which is located at the second bent end of the vehicle body panel.

이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

리어도어(D)의 닫힘 시 차체아우터패널(2)의 서로 단차진 제1·2·3절곡단(2a,2b,2c)과 상응되는 형상을 이루도록 단차진 밀착부(1a)를 형성한 도어(D)의 도어인너패널(1)이 서로 접촉된 상태를 이루면서 상기 절곡단(2a,2b,2c)의 폭 만큼 형성되는 오버랩구간(L)을 형성함과 더불어 도어인너패널(1)의 밀착부(1a)에 구비된 스토퍼(7)의 고정축(7a)이 차체아우터패널(2)의 제2절곡단(2b)에 구비된 스토퍼브라켓트(3)의 돌출단(3b)에 형성된 개구홈(3d)내로삽입되어지고 이에 따라, 상기 스토퍼(7)와 스토퍼브라켓트(3)가 도어(D)의 개·폐 작용에 방해를 주지 않게 된다.When the rear door D is closed, the door having the stepped contact portion 1a formed to have a shape corresponding to the stepped first, second, and third bent ends 2a, 2b, and 2c of the vehicle body panel 2, respectively. While the door inner panel 1 of (D) is in contact with each other, the overlap section L formed by the width of the bent ends 2a, 2b, and 2c is formed, and the door inner panel 1 is closely attached. The opening groove formed in the protrusion end 3b of the stopper bracket 3 provided at the second bending end 2b of the vehicle body panel 2 has the fixed shaft 7a of the stopper 7 provided in the portion 1a. The stopper 7 and the stopper bracket 3 do not interfere with the opening / closing action of the door D by inserting it into 3d.

그러나, 차량의 오프세트 충돌로 인해 리어도어(D)에 충격이 가해져 리어도어(D)가 밀리게 되면, 상기 도어(D)의 도어인너패널(1)의 밀착부(1a)에 구비된 스토퍼(7)가 차체아우터패널(2)의 제2절곡단(2b)에 구비된 스토퍼브라켓트(3)에 의해 저지 당하면서 그 밀림이 차단되어지게 된다.However, when an impact is applied to the rear door D due to an offset collision of the vehicle and the rear door D is pushed down, the stopper provided in the close contact portion 1a of the door inner panel 1 of the door D is closed. (7) is blocked by the stopper bracket (3) provided in the second bent end (2b) of the vehicle body outer panel (2), the jungle is blocked.

즉, 상기 리어도어(D)에 가해지는 충격력에 의해 이 도어(D)의 밀착부(1a)에 구비된 스토퍼(7)의 고정축(7a)이 차체아우터패널(2)의 제2절곡단(2b)에 구비된 스토퍼브라켓트(3)의 돌출단(3b)에 형성된 개구홈(3d)으로 더욱 삽입되면서 그 밀림이 저지 당하게 되어 결국, 도어(D)를 이루는 인너패널(1)의 밀착부(1a)와 차체아우터패널(2)의 제1·3절곡단(2a,2c)에 단차지게 이어진 제2절곡단(2b)이 서로 수평하게 접촉된 상태를 이루더라도 상기 밀착부(1a)와 제2절곡단(2b)의 밀착구간이 밀리면서 슬립을 발생하지 않게 되는 것이다.That is, the fixed shaft 7a of the stopper 7 provided in the close contact portion 1a of the door D is caused by the impact force applied to the rear door D to the second bending end of the vehicle body panel 2. It is further inserted into the opening groove 3d formed in the protruding end 3b of the stopper bracket 3 provided in (2b), and the rolling thereof is blocked, resulting in the close contact of the inner panel 1 forming the door D. 1a and the second bent end 2b, which are stepped to the first and third bent ends 2a and 2c of the vehicle body panel 2, are in contact with each other horizontally. As the close contact section of the second bent end (2b) is pushed, the slip is not generated.

이에 따라, 본 발명은 상기 도어(D)의 인너패널(1)과 차체아우터패널(2)의 오버랩구간(L)을 증가시키지 않고서도 밀림에 의한 슬립현상을 방지하게 되어 도어(D)내에 장착된 글래스나 레귤레이터등과 같은 장치들의 운동 궤적을 방해하지 않고 글래스의 승·하강성을 저하시키지 않게 됨은 물론이다.Accordingly, the present invention prevents slippage due to rolling without increasing the overlap section L of the inner panel 1 of the door D and the vehicle body panel 2 and is mounted in the door D. Of course, the device does not interfere with the motion trajectory of devices such as glass or regulators, and does not lower the liftability of the glass.

이상 설명한 바와 같이 본 발명에 의하면, 충격에 의한 도어의 이동 시 도어가 밀착되는 차체패널부위에 도어의 밀림의 저지하는 스토퍼를 구비하여 도어와 C필라를 이루는 차체아우터패널의 오버랩구간을 증가시키지 않고서도 도어와 차체패널사이의 슬립구간의 형성을 근본적으로 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, a stopper is provided on the body panel portion where the door is in close contact with the door when the door is moved by impact, without increasing the overlap section of the body outer panel forming the door and the C pillar. In addition, there is an effect that can fundamentally prevent the formation of the slip section between the door and the body panel.
