본 고안은 자동차 도어의 충격흡수구조에 관한 것으로, 더욱 상세히는 자동차의 도어는 물론 자동차 도어가 구비되는 자동차 측면의 차체구조를 개선하여 자동차 측면으로부터 가해지는 충격을 효과적으로 흡수토록 하여 승차자를 보호토록 한 것이다.The present invention relates to a shock absorbing structure of a car door, and more particularly, to improve the body structure of the car side as well as the car door so as to effectively absorb the impact from the car side to protect the occupant. will be.

일반적으로 모든 자동차에는 자동차에 탑승할 수 있도록 다수개의 도어가 필연적으로 구비되는데, 이러한 도어는 대체적으로 자동차의 측면에 구비되어 개폐가능토록 구비되어 있는 것이었다.In general, every car is inevitably provided with a plurality of doors to be able to board the car, these doors were generally provided on the side of the car to be opened and closed.

또한 승용차등에 설치되는 자동차 도어일 경우에는 보디와 힌지축으로 체결되어 개폐작동되도록 구성되어 있고, 또한 승합차와 같은 경우에는 슬라이드식으로 개폐가능토록 구성되어 있다.In addition, in the case of an automobile door installed in a passenger car, the body and the hinge shaft are fastened to the opening and closing operation, and in the case of a van, the sliding door is configured to be opened and closed.

지금까지 사용되고 있는 일반적인 자동차 도어(1)는 첨부도면의 제1도에서 보는 바와 같이 자동차 측면의 보디(2)에 지지되어 개폐되는 것으로서, 즉 상기 도어(1)와 보디(2)는 상호 결합되는 가장자리가 서로 대향되는 형태로 절곡되어 있고, 이들은 내부가 빈공간으로 이루어지는 일정한 두께를 가지며 구비되어 있다.The conventional automobile door 1 used so far is supported and opened and supported by the body 2 on the side of the vehicle, as shown in FIG. 1 of the accompanying drawings, that is, the door 1 and the body 2 are coupled to each other. The edges are bent in a form in which they face each other, and they are provided with a constant thickness of an empty space inside.

따라서 도어(1)가 닫히게 되면, 이들 도어(1)와 보디(2)의 가장자리가 서로 이맞물림되는 형태로 체결이 되어 지는 것이고, 또한 도어(1)의 외부면과 보디(2)의 외부면이 서로 일치되면서 닫히게 되는 것이었다.Therefore, when the door 1 is closed, the door 1 and the edges of the body 2 are fastened so that the edges of the door 1 are engaged with each other, and the outer surface of the door 1 and the outer surface of the body 2 are closed. This was to be closed in line with each other.

또한 상기 도어(1)와 보디(2)가 결합되는 이들 사이에는 탄성력을 가지는 고무패킹(3)이 구비되어 기밀을 유지하도록 구성되어 있는 것이었다.In addition, a rubber packing 3 having elastic force is provided between the door 1 and the body 2 to be coupled to each other so as to maintain airtightness.

그러나, 이와 같은 종래의 구성에 있어서는 자동차의 측면에서 추돌 및 충돌이 발생할 경우에 그 충격력이 그대로 도어(1)와 보디(2)에 미치게 됨으로써 이들 도어(1)와 보디(2)는 쉽게 찌그러들게 되는 문제점이 있는 것이었다.However, in such a conventional configuration, when a collision or collision occurs on the side of a vehicle, the impact force is applied to the door 1 and the body 2 as it is, so that the door 1 and the body 2 are easily crushed. There was a problem.

즉, 이들 도어(1)와 보디(2)의 내부에는 별도의 보강재가 없이 빈공간으로 구성되어 있음으로써 강성이 약해 외부에서 가해지는 충격이 그대로 차내로 전달되어지기 때문에 승차자를 보호할 수가 없는 문제점이 있는 것이었다.That is, since the interior of these doors 1 and the body 2 is composed of an empty space without a separate reinforcing material, the rigidity is weak and shocks applied from the outside are transmitted to the inside of the vehicle, thereby preventing the occupant from being protected. This was to be.

본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로 그 목적은 자동차의 측면에서 가해지는 충격으로부터 승차자를 보호하도록 하기 위한 자동차 도어의 충격흡수구조를 제공함에 있다.The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a shock absorbing structure of a car door for protecting a rider from an impact applied from the side of a car.

이러한 목적은 도어 및 보디의 내부에 별도의 충격흡수수단을 구비함으로써 달성되는데, 즉 도어 및 보디의 내부 공간에 충격을 흡수할 수 있는 다수개의 충격흡수부재를 구비하여 이들 외부에서 충격이 가해졌을 경우 이들 충격흡수부재가 그 충격을 완충하도록 함으로써 승차자를 보호하도록 하는 것이 특징인 것이다.This object is achieved by providing separate shock absorbing means inside the door and the body, i.e., when a shock is applied from the outside by providing a plurality of shock absorbing members capable of absorbing shock in the interior space of the door and the body. The shock absorbing member is characterized by protecting the occupant by cushioning the shock.

계속해서 본 고안의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Subsequently, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부된 도면의 제2도는 본 고안이 적용되는 자동차 도어측의 구성을 보인 일부 단면도로서, 도면중 부호 10은 자동차 도어를 나타내고 있고, 부호 20은 자동차 차체의 보디를 나타내고 있다.2 is a partial cross-sectional view showing the configuration of the vehicle door side to which the present invention is applied, where reference numeral 10 denotes a vehicle door, and reference numeral 20 denotes a body of the vehicle body.

상기 도어(10)와 보디(20)의 전체적인 구성은 종래와 동일하나 본 고안에서는 상기 도어(10)와 보디(20)의 내부공간에 각각 별도의 충격흡수수단을 구비한 것이다.The overall configuration of the door 10 and the body 20 is the same as in the prior art, but in the present invention, separate shock absorbing means are provided in the interior spaces of the door 10 and the body 20, respectively.

즉, 상기 도어(10)의 내부공간(P)에 횡방향으로 I빔 형태의 제1충격흡수부재(11)가 설치되고, 이의 제1충격흡수부재(11)는 상기 도어(10)의 내부공간(P)에 별도로 설치되는 제1지지부재(12)와 체결되어 고정 설치된다.That is, the first shock absorbing member 11 having an I beam shape is installed in the inner space P of the door 10 in a lateral direction, and the first shock absorbing member 11 thereof is formed inside the door 10. It is fastened and fixed to the first support member 12 separately installed in the space P.

상기 지지부재(12)는 일정한 강성을 가지는 철판등의 재질로 구성되면서도 내부공간(P)에 용이하게 체결되도록 절곡구성되어 있는 것이고, 이는 제1충격흡수부재(11)를 지지하는 역할도 수행하지만 동시에 충격을 흡수하는 기능도 가지게 되는 것이다.The support member 12 is made of a material such as iron plate having a certain rigidity and is bent to be easily coupled to the internal space (P), which also serves to support the first shock absorbing member (11) At the same time, it also has the ability to absorb shocks.

또한 상기 보디(20)의 내부공간(Q)에는 다수개의 제2충격흡수부재(21)(22)(23)(24)가 설치되어 있고, 이들은 제2지지부재(25)에 의해 지지되면서 체결고정되어 있다.In addition, a plurality of second shock absorbing members 21, 22, 23, and 24 are installed in the internal space Q of the body 20, and they are fastened while being supported by the second support member 25. It is fixed.

상기 제2충격흡수부재(21)(22)(23)(24)들은 동일한 구조를 가지는 것으로, 즉 평면체의 부재가 대략 사각형상으로 절곡되면서 구성되어 있음으로써 여러개의 평판이 몇겹으로 겹쳐진 형상으로 구성되어 있다.The second shock absorbing members 21, 22, 23 and 24 have the same structure, that is, the members of the planar body are bent in a substantially rectangular shape, so that several flat plates are overlapped in several layers. Consists of.

따라서 각부재들은 각각이 충격을 완충할 수 있도록 구성되어 있는 것이고, 또한 이들 각부재들을 지지하는 제2지지부재(25)는 절곡구성되어 상기 각부재들을 유동없이 안정되게 고정하면서도 충격이 가해졌을 경우 이의 충격을 완충하는 기능을 가지게 되는 것이다.Therefore, each member is configured to buffer each shock, and the second support member 25 for supporting these members is bent configuration when the impact is applied while stably fixing each member without flow It will have a function to cushion its impact.

이와 같이 구성되는 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.

즉, 도어(10)와 보디(20)의 외형 구성은 종래와 동일함에 따라 통상에서와 같이 도어(10)는 보디(20)에 지지되는 형태로 설치되어 짐과 동시에 통상에서와 같은 방법으로 도어(10)가 개폐작동 될 것이다.That is, since the outer configuration of the door 10 and the body 20 is the same as in the prior art, the door 10 is installed in the form of being supported by the body 20 as usual, and at the same time, the door 10 will open and close.

본 고안에서는 상기한 도어(10)와 보디(20)의 내부에 각각이 충격을 흡수할 수 있는 충격흡수부재(11)(21)(22)(23)(24)들이 지지부재(12)(25)에 각각 지지된채로 구비되어 있음으로써 자동차의 측면에서 다른 자동차와 추돌 및 충돌이 발생할 경우에 이의 충격을 상기 충격흡수부재들이 흡수하게 되는 것이다.In the present invention, each of the shock absorbing members 11, 21, 22, 23, 24, which can absorb shocks in the door 10 and the body 20, is supported by the support member 12 ( Each of the shock absorbing members absorbs the impact of collision and collision with another vehicle at the side of the vehicle by being supported in each of 25).

즉, 자동차의 측면에서 도어(10)측으로 충격이 가해지면, 먼저 도어(10)내에 구비되는 I형의 제1충격흡수부재(11)가 변형되면서 일차적으로 그 충격을 흡수하게 됨과 동시에 이의 충격흡수부재(11)를 지지하고 있는 제1지지부재(12)도 변형되면서 그 충격을 재차 흡수하게 되는 것이다.That is, when an impact is applied to the door 10 side from the side of the vehicle, first the first shock absorbing member 11 of the type I provided in the door 10 is deformed and absorbs the shock, and at the same time absorbs the shock. The first support member 12 supporting the member 11 is also deformed to absorb the impact again.

계속해서 도어(10)측에서 완전히 흡수되지 못한 충격은 도어(10)를 통해 보디(20)측으로 전달되어 질 것이고, 이의 보디(20)에서는 그 내부에 구비되는 제2충격흡수부재(21)(22)(23)(24)들에 의해 삼차로 흡수되어 지게 된다.The shock that is not completely absorbed on the door 10 side will be transmitted to the body 20 side through the door 10, and in the body 20 thereof, the second shock absorbing member 21 ( 22) (23) (24) to be absorbed tertiarily.

이때 상기 제2충격흡수부재(21)(22)(23)(24)들은 두겹으로 설치되어 있음과 동시에 이들 각부재가 겹치는 상태로 절곡되어 있음으로써 충격을 최대한 흡수하게 되는 것이며, 이와 동시에 이들을 지지하는 제1지지부재(25)도 변형되면서 그 충격을 흡수하게 되는 것이다.In this case, the second shock absorbing members 21, 22, 23, and 24 are installed in two layers, and at the same time, each of the members is bent in an overlapping state to absorb the shock as much as possible. The first support member 25 is also deformed to absorb the shock.

그러므로 이와 같이 된 본 고안은 자동차의 측면에서 추돌 및 충돌에 의해 가해지는 충격을 도어(10)측에서 1, 2차로 어느정도 흡수하게 됨과 아울러 이의 도어(10)측에서 완전히 흡수되지 않은 충격은 보디(20)측에서 3, 4차로 흡수하게 됨으로써 자동차내에 승차한 승차자를 안전하게 보호할 수가 있게 되는 효과를 가지게 되는 것이다.Therefore, the present invention, as described above, absorbs some of the impacts caused by collisions and collisions on the side of the vehicle to the first and second sides of the door 10 side, and the impact that is not completely absorbed on the side of the door 10 is the body ( By absorbing the 3rd and 4th cars from the 20) side, the occupants in the car can be safely protected.
