본 발명은 자동차 도어용 임펙트바에 관한 것으로, 특히 스프링을 이용하여 적당한 강도와 유연성을 주므로서 측면충돌시 발생되는 충격을 완충시킬 수 있는 구조를 갖도록 한 자동차 도어용 임펙트바에 관한 것이다.The present invention relates to an impact bar for an automobile door, and more particularly, to an impact bar for an automobile door having a structure capable of buffering an impact generated during a side collision while providing proper strength and flexibility using a spring.
제1도 (a) 및 (b)에서 잘 보여지는 바와 같이, 종래의 임펙트바(a)는 소정 직경과 길이를 갖는 고장력 강관으로써 자동차 도어(b)의 내부에 브래킷(c)에 의해 고정 설치되어 있다.As is well seen in Figs. 1 (a) and (b), the conventional impact bar (a) is a high-strength steel pipe having a predetermined diameter and length, which is fixedly installed by the bracket (c) inside the automobile door (b). It is.
상기와 같이 자동차 도어(b)내부에 고정 설치되어 있는 고장력 강간으로 제작된 종래의 임펙트바(a)는 강도 높으나 측면충돌시 발생되는 충격을 흡수할 수 있는 완충작용을 할 수 없기 때문에 차내에 있는 탑승자에게 충격이 그대로 전달될 수 있다는 안전상으로 문제점이 있었다.As described above, the conventional impact bar (a) made of high-strength rape fixedly installed inside the automobile door (b) has a high strength but cannot absorb a shock generated at the time of side collision. There was a problem in safety that the shock can be transmitted to the occupants as it is.
상기 문제점을 고려하여 본 발명은 충분한 강도는 물론 측면충돌시 발생되는 충격을 흡수할 수 있는 유연성을 동시에 갖도록 하므로서 탑승자에게 충격이 최대한 전달되지 않도록 할 수 있는 자동차 도어용 임펙트바를 제공하는 것을 목적으로 한다.In view of the above problems, an object of the present invention is to provide an impact bar for a car door that can prevent a shock from being transmitted to the occupant as much as possible while simultaneously having sufficient strength and flexibility to absorb a shock generated during a side collision. .
상기 목적을 달성하기 위한 본 발명은 자동차 도어용 임펙트바에 있어서, 소정 직경과 길이로 권장형성되는 제1스프링 부재와 ; 소정 직경과 길이로 권장형성되고, 권장방향이 상기 제1스프링 부재의 권장방향과 반대방향이 되도록 상기 제1스프링 부재의 내측에 끼움조립되는 제2스프링 부재와 ; 소정 직경과 길이를 갖는 환봉으로써 일단부가 상기 제2스프링 부재의 양단부에 각각 끼움결합되고 타단부가 브래킷에 용접되어 자동차 도어의 내부에 고정설치되는 복수의 결합봉으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides an impact bar for an automobile door, comprising: a first spring member that is recommended to have a predetermined diameter and length; A second spring member that is recommended to be formed in a predetermined diameter and length, and is fitted to the inside of the first spring member so that the recommended direction is opposite to the recommended direction of the first spring member; A round bar having a predetermined diameter and length is characterized by consisting of a plurality of coupling rods, one end of which is respectively fitted to both ends of the second spring member and the other end is welded to the bracket and fixedly installed inside the automobile door.
이하, 첨부된 도면을 참조하여 본 발명의 실시예를 구체적으로 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도 (a) 및 (b)를 참조하면, 도면부호 10은 자동차 도어를 나타낸다.Referring to Figures 2 (a) and (b), reference numeral 10 denotes a car door.
상기 자동차 도어(10)는 내부에 복수의 임펙트바(11)가 브래킷(14,15)에 의해 고정 설치되어 있다.In the vehicle door 10, a plurality of impact bars 11 are fixed to the inside of the vehicle door 10 by brackets 14 and 15.
상기 임펙트바(11)는 제1스프링 부재(12)와 제2스프링 부재(13)로 구성된다.The impact bar 11 is composed of a first spring member 12 and a second spring member 13.
상기 제1스프링 부재(12)는 소정 직경과 길이를 갖고 권장형성되고, 상기 제2스프링 부재(13)는 소정 직경과 길이로 권장형성되어 권장방향이 상기 제1스프링 부재(12)와 반대가 되도록하여 상기 제1스프링 부재(12)의 내측에 끼움조립 된다.The first spring member 12 is recommended to have a predetermined diameter and length, and the second spring member 13 is recommended to have a predetermined diameter and length so that a recommended direction is opposite to that of the first spring member 12. It is fitted to the inside of the first spring member 12 so as to be assembled.
상기와 같은 구성을 갖는 상기 임펙트바(11)의 양단부에는 복수의 결합봉(16,17)이 끼움결합된다.A plurality of coupling rods 16 and 17 are fitted to both ends of the impact bar 11 having the configuration as described above.
상기 복수의 결합봉(16,17)은 소정 직경과 길이를 갖는 금속제의 환봉으로써 일단부는 각각 상기 임펙트바(11)의 제2스프링 부재(13) 양단부에 끼움결합되고, 타단부는 자동차 도어(10)의 내부 소정 위치에 각각 대향되게 용접결합되어 있는 브래킷(14,15)에 용접되어 고정 결합된다.The plurality of coupling rods 16 and 17 are round bars made of metal having predetermined diameters and lengths, and one end thereof is fitted to both ends of the second spring member 13 of the impact bar 11, and the other end thereof is an automobile door ( 10 is welded to and fixed to the brackets 14 and 15 which are respectively welded to face each other at predetermined positions.
이하, 상기 구성에 따른 본 발명의 작용 및 효과를 구체적으로 설명한다.Hereinafter, the operation and effects of the present invention according to the above configuration will be described in detail.
제2도 (a) 및 (b)를 다시 참조하면, 상기 임펙트바(11)는 제1스프링 부재(12)와 제2스프링 부재(13)가 서로 권장방향이 반대가 되도록 끼움결합되어 있기 때문에 측방력에 대한 충분한 강도를 갖을 수 있고, 상기 제1 및 제2스프링 부재(12,13)의 자체탄성력에 의해 유연성을 갖고 있기 때문에 측면충돌시 발생되는 충격에 대하여 상기 임펙트바(11)는 1차적으로 조립구조에 의한 발생되는 강도로 버티면서 자체탄성력에 의해 반대방향으로 휘면서 충격을 흡수하여 탑승자에게 충격이 전달되는 것을 확실히 방지할 수 있는 것이다.Referring again to FIGS. 2A and 2B, since the impact bar 11 is fitted with the first spring member 12 and the second spring member 13 so that their recommended directions are opposite to each other. Since the impact bar 11 may have sufficient strength against the lateral force and is flexible by the self-elasticity of the first and second spring members 12 and 13, the impact bar 11 may be 1 It is possible to reliably prevent the shock from being transmitted to the occupant by absorbing the impact while bending in the opposite direction by the self-elastic force while being subjected to the strength generated by the assembly structure.
따라서, 본 고안은 기존의 임펙트바(11)를 복수의 스프링 부재로 형성시키므로서 충분한 강도는 물론 충격을 흡수할 수 있는 완충효과까지 갖도록 하므로서 탑승자에게 충격이 전달되는 것을 확실히 방지할 수 있는 매우 우수한 발명인 것이다.Therefore, the present invention is to form a conventional impact bar 11 with a plurality of spring members to have a sufficient strength as well as a shock-absorbing effect that can absorb the shock, while being very excellent to prevent the shock is transmitted to the occupant It is an invention.
