이하에서는 첨부된 도면의 바람직한 실시예를 들어 본 발명을 상세하게 설명 한다. 첨부된 도면의 도 1은 종래의 박스형 충격흡수부재가 설치된 모습을 보인 상태도, 도 2는 본 발명의 일실시예에 따른 자동차 도어용 충격흡수부재의 사시도, 도 3은 본 발명의 일실시예에 따른 자동차 도어용 충격흡수부재의 정면도, 도 4는 본 발명의 일실시예에 따른 자동차 도어용 충격흡수부재의 평면도, 도 5는 본 발명의 일실시예에 따른 자동차 도어용 충격흡수부재의 단면도, 도 6은 본 발명의 일실시예에 따라 자동차 도어용 충격흡수부재를 설치한 상태 단면도이다.Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the accompanying drawings. Figure 1 of the accompanying drawings is a state diagram showing a conventional box-shaped shock absorbing member is installed, Figure 2 is a perspective view of a shock absorbing member for a car door according to an embodiment of the present invention, Figure 3 is an embodiment of the present invention 4 is a plan view of a shock absorbing member for a car door according to an embodiment of the present invention, and FIG. 5 is a plan view of the shock absorbing member for a car door according to an embodiment of the present invention. 6 is a cross-sectional view of a state in which an impact absorbing member for a car door is installed according to an embodiment of the present invention.

본 발명의 일실시예에 따른 자동차 도어용 충격흡수부재(10)는 합성수지 재질로서, 사출성형에 의해 일체로 형성되는 것이 바람직하고, 도 2 내지 도 5에 도시된 바와 같이, 크게 내벽체(20)와 외벽체(30), 연결부(40) 및 지지부(50)로 구분되며, 도 6에 도시된 바와 같이 도어트림(60)의 일측에 결합 설치된다.The shock absorbing member 10 for an automobile door according to an embodiment of the present invention is a synthetic resin material, preferably formed integrally by injection molding, and as shown in FIGS. 2 to 5, the inner wall body 20 is large. ) And the outer wall 30, the connection portion 40 and the support 50 is divided into, as shown in Figure 6 is installed coupled to one side of the door trim (60).

여기서 내벽체(20)는 전체적으로 직육면체의 컵 형상이고, 내부에는 상측이 개구된 내측공간부(21)가 형성되는데, 이 내측공간부(21)는 하단으로 갈수록 폭이 좁아진다. 즉, 도 5에 도시된 바와 같이, 내벽체(20)의 단면상 상단에서 하단의 바닥면(22)으로 내려갈수록 내측으로 비스듬하게 경사져서 형성되는 것이다.Here, the inner wall 20 has a cup shape of a rectangular parallelepiped as a whole, and an inner space portion 21 having an upper side opened therein is formed, and the inner space portion 21 becomes narrower toward the lower end thereof. That is, as shown in Figure 5, the inner wall 20 is formed to be inclined inclined inwardly toward the bottom surface 22 of the lower end from the upper end in the cross section.

이때, 내벽체(20)가 내측경사면(21a)을 따라 붕괴되면서 충분히 충격을 흡수할 수 있도록, 도 6에 도시된 바와 같이 내벽체(20)의 바닥면(22)은 도어트림(60)의 일측면에 지지되는 것이 바람직하다.At this time, the inner wall 20 is collapsed along the inner inclined surface (21a) to absorb the shock sufficiently, as shown in Figure 6, the bottom surface 22 of the inner wall (20) of the door trim 60 It is preferable to be supported on one side.

즉, 충격흡수부재(10)가 설치되는 도어트림(60)의 설치면이 평평한 경우, 바 닥면(22)은 후술하는 지지부(50)와 같은 높이에 형성되는 것이다. That is, when the installation surface of the door trim 60, in which the shock absorbing member 10 is installed, is flat, the bottom surface 22 is formed at the same height as the support 50 described later.

도 5에 도시된 바와 같이, 외벽체(30)는 내벽체(20)의 외측에 소정거리 이격하여, 내벽체(20)를 둘러싸면서 형성되는데, 외벽체(30)의 상단은 내벽체(20)의 상단보다 낮게 단차져서 형성되고, 내벽체(20)의 상단과 외벽체(30)의 상단은 연결부(40)에 의해 서로 연결된다.As shown in FIG. 5, the outer wall body 30 is formed to surround the inner wall body 20 at a predetermined distance from the outer side of the inner wall body 20, and an upper end of the outer wall body 30 is formed on the inner wall body 20. It is formed to be lower than the upper end, the upper end of the inner wall body 20 and the upper end of the outer wall 30 is connected to each other by the connecting portion (40).

이때, 연결부(40)는 내벽체(20)의 상단에서 외측 하향으로 절곡되어 외벽체(30)의 상단에 연결되고, 이에 따라 내벽체(20)와 외벽체(30), 연결부(40)에 의해 구획되면서 하측이 개구된 외측공간부(31)가 형성된다.At this time, the connecting portion 40 is bent downward from the upper end of the inner wall body 20 is connected to the upper end of the outer wall body 30, accordingly partitioned by the inner wall body 20, outer wall body 30, the connecting portion 40 The outer space portion 31 is opened while the lower side is formed.

또한, 외벽체(30)는 내벽체(20)의 형상에 대응되는 직육면체 형상으로 형성되는 것이 바람직하고, 하단으로 갈수록 폭이 넓어진다. 즉, 외벽체(30)의 단면상 상단에서 하단으로 내려갈수록 외측으로 비스듬하게 경사져서 형성되는 것이다.In addition, the outer wall body 30 is preferably formed in a rectangular parallelepiped shape corresponding to the shape of the inner wall body 20, and the width becomes wider toward the lower end. That is, it is formed obliquely outwardly from the upper end to the lower end in the cross section of the outer wall 30.

한편, 외벽체(30)의 하단에서 외측으로 절곡되어 지지부가 수평으로 연장 형성되는데, 이 지지부(50)는 도어트림(60)의 하부 일측에 융착되거나, 볼트 등의 체결수단으로 결합된다.On the other hand, bent outward from the lower end of the outer wall body 30 to form a support extending horizontally, the support 50 is fused to one side of the lower portion of the door trim 60, or is coupled by fastening means such as bolts.

즉, 충격흡수부재(10)는 도 6에 도시된 바와 같이, 지지부(50)가 도어트림(60)에 결합된 상태에서 내벽체(20)가 인너패널(70) 방향으로 돌출되도록 설치되는 것이다.That is, the shock absorbing member 10 is installed such that the inner wall body 20 protrudes toward the inner panel 70 in a state in which the support 50 is coupled to the door trim 60 as shown in FIG. 6. .

이때, 충격흡수부재(10)의 상단이 인너패널(70)로부터 약간 거리를 두고 이 격하도록 설치되는 것이 바람직하다.At this time, the upper end of the shock absorbing member 10 is preferably installed so as to be spaced apart from the inner panel 70 slightly.

이처럼, 내벽체(20)와 외벽체(30)가 단차져서 형성됨에 따라, 충돌시 초기에는 내벽체(20)가 도어트림(미도시)과 인너패널(70) 사이의 공간을 지지하는 역할을 하며, 1차적으로 충격에너지를 흡수하게 된다. As such, as the inner wall 20 and the outer wall 30 are formed stepped, the inner wall 20 serves to support the space between the door trim (not shown) and the inner panel 70 at the time of collision. Firstly, the impact energy is absorbed.

이후, 충돌이 진행되면 인너패널(70)이 탑승자 방향으로 밀려들어오고, 내벽체(20)는 내측경사면(21a)을 따라 붕괴되면서, 도어트림과 인너패널(70) 사이의 공간을 지지하는 기능을 상실하게 되는데, 이때 외벽체(30)가 인너패널(70)과 접촉하면서 초기 반력을 일정구간 유지하여 2차적으로 충격에너지를 흡수하는 역할을 하게 된다.Subsequently, when the collision proceeds, the inner panel 70 is pushed toward the occupant, and the inner wall 20 collapses along the inner inclined surface 21a, thereby supporting a space between the door trim and the inner panel 70. In this case, the outer wall 30 is in contact with the inner panel 70 to maintain the initial reaction force for a period of time to serve to absorb the secondary impact energy.

즉, 내벽체(20)의 붕괴 진행중에 외벽체(30)가 인너패널(70)과 접촉하게 되면, 외벽체(30)가 외측경사면(31a)을 따라 붕괴되면서 내벽체(20)와 함께 충격에너지를 흡수하게 되는 것이다. That is, when the outer wall 30 contacts the inner panel 70 during the collapse of the inner wall 20, the outer wall 30 collapses along the outer inclined surface 31a and imparts impact energy with the inner wall 20. Will be absorbed.

이때, 충격에 대한 내벽체(20)의 초기 반력은 연결부(40)에 형성되는 연결부 홈(41)의 크기와 개수를 적절히 선택함으로써 조절할 수 있고, 외벽체(30)의 강성 역시 외벽체(30)에 형성되는 외벽체 홈(32)의 크기와 개수를 적절히 선택함으로써 조절 가능하다.At this time, the initial reaction force of the inner wall body 20 against the impact can be adjusted by appropriately selecting the size and number of the connection groove 41 formed in the connecting portion 40, the rigidity of the outer wall body 30 to the outer wall body 30 It is possible to adjust by appropriately selecting the size and number of the outer wall grooves 32 to be formed.

즉, 홈(32,41)의 크기가 클수록 그리고 개수가 많을 수록 반력은 낮아지고 강성이 약화되어 쉽게 붕괴되는 것이며, 아울러 각각의 홈(32,41)은 충돌방향 즉, 높이방향으로 절개되어 각각 연결부(40)와 외벽체(30)의 외주면을 따라 다수 형성되는 것이 바람직하다.That is, the larger the size of the grooves 32 and 41 and the larger the number, the lower the reaction force and the weaker the rigidity, the easier it is to collapse. In addition, each of the grooves 32 and 41 is cut in the collision direction, that is, the height direction. It is preferable that a large number is formed along the outer circumferential surface of the connecting portion 40 and the outer wall body 30.

따라서, 종래 합성수지 재질의 충격흡수부재는 충격에너지 흡수를 위해 초기 반력이 높은 경향이 있었고, 이에 따라 충돌시 인체 상해 정도가 크다는 문제가 있으나, 본 발명의 일실시예에 따른 충격흡수부재(10)는 초기반력이 종래의 것보다 낮으면서도 충격에너지 흡수는 더 우수하다는 장점이 있다.Therefore, the conventional shock absorbing member of the synthetic resin material tends to have a high initial reaction force for absorbing the impact energy, and thus there is a problem that the degree of injury to the human body is large when the collision, the shock absorbing member 10 according to an embodiment of the present invention Although the initial reaction force is lower than the conventional one, there is an advantage that the shock energy absorption is better.
