Description

자동차의 도어 충격흡수구조( A structure for absorbing an impact of a door of an automobile )A structure for absorbing an impact of a door of an automobile

본 고안은 자동차의 도어의 내부에 장착된 충격흡수부재에 관한 것으로, 특히 충격흡수부재 연장부에 고정된 걸쇠가 필러에 형성된 걸림홈에 삽입될 수 있게 함으로로써 도어변형에 의한 탑승객의 상해치를 줄일 수 있도록 한 자동차의 도어 충격흡수구조에 관한 것이다.The present invention relates to a shock absorbing member mounted inside the door of a vehicle, and in particular, the latch fixed to the shock absorbing member extension portion can be inserted into the locking groove formed in the filler to reduce the injury of passengers due to the door deformation. The present invention relates to a door shock absorbing structure of a vehicle.

일반적으로 자동차의 도어(101)는 도 2 및 도 3에 나타낸 바와 같이 차체의 측면을 이루는 필러(102)에 도어(101)개폐동작에 따른 하중을 지지하기 위한 체크링크(103)를 매개로 힌지결합되어지고, 측면충돌시에 충돌차량에 의해 도어(101)가 차실내부로 밀리는 것을 방지하면서 탑승자등을 보다 안전하게 보호하기 위해 도어(101)의 내부에 충격흡수수단이 장착되어 있는 데, 이와 같은 충격흡수수단은 도어(101)의 하부에 도어(101)를 가로지르는 방향으로 배열되면서 충격흡수부재(104)의 양쪽 선단부위가 장착브라켓에 체결되어 지지된 구조로 되어 있다.In general, the door 101 of the vehicle hinges through a check link 103 for supporting a load according to the opening / closing operation of the door 101 to the filler 102 forming the side of the vehicle body as shown in FIGS. 2 and 3. The shock absorbing means is coupled to the inside of the door 101 to prevent the door 101 from being pushed into the inside of the vehicle compartment by the collision vehicle during side impacts. The shock absorbing means has a structure in which both front ends of the shock absorbing member 104 are fastened to the mounting bracket while being supported in a direction crossing the door 101 at the bottom of the door 101.

즉, 도어(101)의 내측패널(101a)과 외측패널(101b)이 이루는 공간내부에 충격흡수부재(104)가 길게 연장되어 배열되고, 이 충격흡수부재(104)의 양선단부는 장착브라켓(105)의 한쪽 절곡부(105a)에 용접등으로 장착되어 있으며, 이 장착브라켓(105)의 다른쪽 절곡부(105a)는 도어(101)의 내측패널(101a)에 부착되어 충격흡수부재(104)를 지지하게 되는 한편, 상기 장착브라켓(105)의 지지강성을 향상시키기 위해 지지브라켓(106)이 장착브라켓(105)의 한쪽 절곡부(105a)와 내측패널(101a)에 각각 부착되어 있다.That is, the shock absorbing member 104 is extended and arranged in the space formed by the inner panel 101a and the outer panel 101b of the door 101, and both ends of the shock absorbing member 104 are provided with a mounting bracket ( One bent portion 105a of 105 is mounted by welding or the like, and the other bent portion 105a of the mounting bracket 105 is attached to the inner panel 101a of the door 101 to absorb the shock absorbing member 104. In order to improve the support rigidity of the mounting bracket 105, the support bracket 106 is attached to one bent portion 105a and the inner panel 101a of the mounting bracket 105, respectively.

상기한 바와 같은 종래의 도아의 충격흡수구조에서는 측면충돌시에 체크링크(103)가 결합된 도어(101)전방은 충격흡수부재(104)와 체크링크(103)에 의해 충격을 흡수함과 더불어 도어(101)가 변형되어 차실내로 밀려 들어오는 것을 방지해줄 수 있으나 체크링크(103) 반대편은 도어(101)에 내장된 도어래치(107)에 의해서만 지탱해주기 때문에 충격량이 클 경우에는 도어래치(107)만으로 도어가 변형되어 차실내부로 밀려들어오는 것을 방지하기가 미흡하여 탑승객을 보다 안전하게 보호할 수 없다는 문제점이 있었다.In the conventional shock absorbing structure of the door as described above, the front of the door 101 coupled with the check link 103 during side impact absorbs the shock by the shock absorbing member 104 and the check link 103. The door 101 may be deformed and prevented from being pushed into the interior of the vehicle. However, since the opposite side of the check link 103 is supported only by the door latch 107 built in the door 101, the door latch 107 when the impact amount is large. There was a problem that the door is deformed by only to be deformed into the interior of the vehicle is insufficient to protect the passengers more securely.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 도어에 설치된 도어래치와 충격흡수부재 연장부에 고정된 걸쇠가 필러의 스트라이커와 걸림홈에 각각 삽입될 수 있게 함으로로써 도어변형으로부터 탑승객을 보다 안전하게 보호할 수 있도록 된 자동차의 도어 충격흡수구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, the door latch installed in the door and the clasp fixed to the shock absorbing member extension portion can be inserted into the striker and the engaging groove of the filler respectively, so that the passenger from the door deformation The purpose of the present invention is to provide a shock absorbing structure of a door car that can be more securely protected.

상기한 바의 목적을 달성하기 위한 본 고안은, 도어의 내측패널과 외측패널사이의 공간하부에 도어를 가로지르는 방향으로 길게 연장되어 충격흡수부재의 양쪽 선단부위가 내측패널에 부착된 장착브라켓에 장착되어 지지되고, 이 장착브라켓의 지지강성을 향상시키기 위해 지지브라켓이 장착브라켓하부에 부착된 자동차의 도어 충격흡수구조에 있어서, 상기 충격흡부재의 일측선단부가 상기 내측패널을 관통하여 뻗어나온 연장부가 형성되고, 이 연장부에 걸쇠가 구비된 구조로 된 것을 특징으로 한다.The present invention for achieving the object of the above bar, extending in the direction across the door to the lower portion of the space between the inner panel and the outer panel of the door so that both ends of the shock absorbing member to the mounting bracket attached to the inner panel In the door shock absorbing structure of a vehicle mounted and supported, the support bracket is attached to the bottom of the mounting bracket to improve the support rigidity of the mounting bracket, the one end of the shock absorbing member extending through the inner panel An additional portion is formed, and the extension portion has a structure provided with a clasp.

따라서 상기와 같은 구조로 이루어진 본 고안의 충격흡수구조에 의하면, 도어를 닫았을 때 충격흡부재의 걸쇠가 차체의 측면을 이루는 필러에 형성된 걸림홈에 삽입되게 되므로써, 자동차의 측면충돌시에 충격을 효과적으로 흡수할 수 있음과 더불어 도어가 차실내부로 밀려들어오는 것을 방지할 수 있게 된다.Therefore, according to the shock absorbing structure of the present invention made of the above structure, when the door is closed, the latch of the shock absorbing member is inserted into the locking groove formed in the filler forming the side of the vehicle body, thereby impacting the side impact of the vehicle In addition to being able to absorb effectively, it is possible to prevent the door from being pushed into the vehicle interior.
