본 고안은 자동차 문의 충격 흡수 구조에 관한 것으로, 자동차 운행중 측면 충돌사고 발생시 운전자를 안전하게 보호하고 차체의 손산을 최소화 할 수 있도록 보강부를 구비한 자동차 문의 충격 흡수 구조에 관한 것이다.The present invention relates to a shock absorbing structure of the automobile door, and to a shock absorbing structure of the automobile door provided with a reinforcement part to safely protect the driver and minimize the loss of the vehicle body in the event of a side collision accident during driving.

자동차가 증가함에 따라 상대적으로 교통사고가 증가하고 그것으로 인하여 사상자도 증가하고 있다.As automobiles increase, traffic accidents increase and casualties increase.

그러므로 자동차 설계시 자동차의 성능에 못지않게 차체의 강도도 중요시하여 자동차를 설계하고 있다.Therefore, when designing a car, the strength of the car body is as important as the performance of the car.

이와같이 자동차 설계시 자동차의 강도가 중요시 여겨짐에 따라 측면 충돌시 실질적으로 운전자를 보호하는 자동차 문(20)의 내부 구조를 측면 충돌시 가해지는 충격 하중을 흡수할 수 있도록 형성하고 있다.As the strength of the vehicle is considered to be important in the design of the vehicle, the internal structure of the vehicle door 20 which substantially protects the driver during side collision is formed to absorb the impact load applied during the side collision.

그 형상은 제 2 도에 도시된 바와같이 안쪽 부재(23)에 충격 흡수 부재(24)가 고정되고 바깥 부재(21)의 안쪽면에는 중공봉(22)이 접착재(S)에 의하여 고정되어 있다.As shown in FIG. 2, the shock absorbing member 24 is fixed to the inner member 23, and the hollow bar 22 is fixed to the inner surface of the outer member 21 by the adhesive material S. As shown in FIG. .

상기와 같은 형상의 자동차 문(20)이 구비된 자동차가 측면 충돌에 의하여 충격 하중을 받게되면 중공봉(22)이 접착제(S)에 의하여 고정된 바깥 부재(21)에 일차적으로 충격 하중이 전달된다.When the vehicle provided with the vehicle door 20 having the shape as described above receives an impact load by side impact, the impact load is primarily transmitted to the outer member 21 in which the hollow bar 22 is fixed by the adhesive S. do.

충격 하중을 전달받은 바깥 부재(21)는 안쪽면에 접착제(S)에 의하여 고정된 중공봉(22)에 의하여 강성을 유지하며 자동차 문(20)의 변형을 방지하고 충격을 흡수 및 분산 시킨다.The outer member 21, which receives the impact load, maintains rigidity by the hollow bar 22 fixed to the inner surface by the adhesive S, prevents deformation of the automobile door 20, and absorbs and disperses the impact.

그리고 측면 충돌에 의하여 전달되는 충격 하중이 강하여 바깥 부재(21)가 충력 하중을 흡수하지 못하고 변형되면 이차적으로 안쪽 부재(23)에 고정된 충격 흡수 부재(24)가 충격을 흡수하여 운전자에게 전달되는 충격 하중을 최소화 시켜 운전자를 사고로 부터 안전하게 보호한다.In addition, when the impact member transmitted by the side impact is strong and the outer member 21 does not absorb the shock load and is deformed, the shock absorbing member 24 fixed to the inner member 23 is absorbed and transmitted to the driver. Minimize the impact load to protect the driver from accidents.

그러나 일차적인 충격 흡수과정에 있어서 바깥 부재(21)가 측면 충돌에 의하여 전달되는 충격 하중을 흡수하지 못하고 쉽게 변형된다.However, in the primary shock absorbing process, the outer member 21 does not absorb the shock load transmitted by the side impact and is easily deformed.

또한 충격 하중에 의하여 바깥 부재(21) 변형이 발생하면 이차적인 충격 흡수 작용을 하는 충격 흡수 부재(24)에 중공봉(22)이 먼저 접하게 된다.In addition, when the outer member 21 is deformed by the impact load, the hollow bar 22 is first in contact with the shock absorbing member 24 having a secondary shock absorbing action.

그러므로 중공봉(22)에 의하여 충격 하중이 충격 흡수 부재(24)의 일부분에 집중되므로 충격 흡수 부재(24)가 충격 하중을 흡수를 하지 못하고 운전자에게 충격 하중을 전달시켜 운전자의 안전을 위협하며 자동차를 크게 파손시킨다.Therefore, since the impact load is concentrated on a part of the shock absorbing member 24 by the hollow bar 22, the shock absorbing member 24 does not absorb the shock load and transmits the shock load to the driver, thereby threatening the driver's safety. It greatly breaks down.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로 자동차의 측면 충돌사고 발생시 운전자를 안전하게 보호하고 자동차 문 및 차체의 손상을 최소화 할 수 있도록 충격 하중을 흡수 및 분산 시키는 보강부를 구비한 형상을 제공하는 것을 본 고안의 목적으로 한다.The present invention has been devised to solve the above problems to provide a shape having a reinforcing portion for absorbing and distributing the impact load to safely protect the driver in the event of a side collision of the car and to minimize damage to the car door and body. It is the purpose of the present invention.

상기 목적을 달성하기 위해서는 중공봉에 융착 고정되고 바깥 부재에 접착재에 의하여 고정된 고정 부재에 판재의 양측을 절곡시켜 판재와 이루는 각이 예각을 형성하도록 절곡시키고 양단을 외측으로 절곡한 절곡 부재의 양단을 융착 고정하며 각각의 절곡부는 곡면을 형성하도록 한 보강부를 구비함으로 상술한 소기의 목적을 달성할 수 있다.In order to achieve the above object, both ends of the plate member are bent to the fixing member fused and fixed to the hollow rod and fixed by the adhesive member to the outer member so that the angle formed with the plate member is bent to form an acute angle, and both ends of the bending member are bent outwardly. By fusing and fixing the respective bent portions having a reinforcing portion to form a curved surface can achieve the above-mentioned object.

이하 도면에 의하여 설명하면 다음과 같다.Referring to the drawings as follows.

제 3 도에 도시된 바와같이 중공봉(12)이 융착 고정된 바깥 부재(11)에 접착재(S)에 의하여 고정된 고정부재(13b)에 판재의 양측을 서로 대향하게 ㄷ자로 절곡시켜 판재와 이루는 각이 예각을 형성하도록 절곡시키고, 양단을 외측으로 절곡하여 판재와 수평을 이루도록 형성하며, 각각의 절곡부는 곡면을 형성하도록 한 절곡 부재(13a)의 양단을 융착 고정하여 형성한 보강부를 구성한 것이다.As shown in FIG. 3, both sides of the plate are bent in a U-shape to face each other on the fixing member 13b fixed by the adhesive S to the outer member 11 to which the hollow bar 12 is fused and fixed. Each angle is bent to form an acute angle, and both ends are bent to the outside to form a horizontal line, and each bent portion constitutes a reinforcement part formed by fusion fixing both ends of the bending member 13a to form a curved surface. .

이하 작용과 효과에 대하여 설명하면 다음과 같다.Hereinafter, the operation and effect will be described.

상기와 같은 자동차 문(10)를 구비한 자동차에 측면 충돌에 의한 충격 하중이 전달되면 일차적으로 바깥 부재(11)가 충격 하중을 전달받는다.When the impact load due to the side impact is transmitted to the vehicle having the vehicle door 10 as described above, the outer member 11 receives the impact load primarily.

충격 하중을 전달받은 바깥 부재(11)는 중공봉(12)과 보강부(13)를 통하여 충격 하중을 흡수하고 분산시켜 운전자를 안전하게 보호하고 자동차 문(10)의 변형과 차체의 손상을 최소화 한다.The outer member 11, which receives the impact load, absorbs and distributes the impact load through the hollow rod 12 and the reinforcing portion 13 to protect the driver and to minimize the deformation of the vehicle door 10 and damage to the vehicle body. .

그리고 측면 충돌에 의하여 바깥 부재(11)에 전달되는 충격 하중이 너무 강하여 바깥 부재(11)가 견디지 못하고 변형되면 보강부(13)의 절곡 부재(13a)가 안쪽 부재(14)의 안쪽면에 고정된 충격 흡수 부재(15)의 바깥면에 고르게 접촉하여 바깥 부재(11)가 흡수하지 못한 충격 하중을 충격 흡수 부재(15)가 흡수한다.And when the impact load transmitted to the outer member 11 by the side collision is too strong to deform the outer member 11, the bending member 13a of the reinforcing portion 13 is fixed to the inner surface of the inner member 14 The shock absorbing member 15 absorbs the impact load that the outer member 11 does not absorb by evenly contacting the outer surface of the shock absorbing member 15.

그러므로 운전자에게 전달되는 충격 하중을 최소하여 운전자를 안전하게 보호할 수 있다.Therefore, it is possible to protect the driver by minimizing the impact load transmitted to the driver.

이상과 같이 보강부를 구비한 자동차 문 구조를 형성함으로서 운전자의 안전을 확보하고 자동차 문화 차체의 파손을 최소화 할 수 있는 매우 유용한 것이다.As described above, by forming a car door structure having a reinforcement part, it is very useful to secure driver's safety and minimize damage to a car culture body.
