Description
본 발명은 측면충돌이 일어날 때에 국부단면붕괴를 방지하기 위하여 안전빔에 보강부재를 설치한 자동차용 도어에 관한 것이다.The present invention relates to an automobile door provided with a reinforcing member in a safety beam to prevent local cross-sectional collapse when a side collision occurs.
일반적으로 자동차용 도어에는 측면충돌이 일어날 때에 승객의 안전을 위하여 도어의 외판에 브라켓을 통하여 안전빔(safety beam)을 설치한다.In general, a safety beam is installed in a vehicle door through a bracket on the outer plate of the door for the safety of the passenger when side collision occurs.
상기한 안전빔(6)은 충격빔(impact beam) 또는 충격바(impact bar)라고도 하며, 제3도에 나타낸 바와 같이 원통형상으로 형성되고 양 끝부분을 브라켓에 용접 등에 의하여 고정한 뒤 도어의 외판에 브라켓을 고정하는 것에 의하여 자동차용 도어에 설치된다.The safety beam 6 is also called an impact beam (impact beam) or impact bar (impact bar), as shown in Figure 3 is formed in a cylindrical shape and fixed to both ends of the bracket by welding or the like to the outer plate of the door It is installed on the door of the car by fixing the bracket to.
상기와 같이 구성되는 종래의 안전빔은 측면충돌이 일어날 때에 제4도에 나타낸 바와 같이 최대 굽힘모멘트가 작용하는 안전빔(6)의 중앙부(7)에서 국부단면붕괴가 일어나기 때문에 구조적 강도의 중요 요소인 중앙부(7)의 강도를 확보하기 위하여 불필요하게 안전빔(6)의 전체적인 강도와 중량이 크게 설정되고, 이것이 자동차의 중량증가와 원가상승의 원인이 된다는 문제가 있다.The conventional safety beams constructed as described above are important elements of structural strength because local cross-sectional collapse occurs at the central portion 7 of the safety beam 6, in which the maximum bending moment acts, as shown in FIG. In order to secure the strength of the phosphorus central portion 7, the overall strength and weight of the safety beam 6 are unnecessarily set large, which causes a problem of weight increase and cost increase of the vehicle.
본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 안전빔의 중앙부에서 일어나는 국부단면붕괴를 방지하면 안전빔의 붕괴강도를 높일 수 있다는 데 착안하여 국부단면붕괴가 일어나는 부위에 보강부재를 설치하여 측면충돌에 대한 강도를 보강한 자동차용 도어를 제공하는 것이다.An object of the present invention is to solve the above problems, by preventing the local cross-section collapse occurring in the center of the safety beam to increase the collapse strength of the safety beam, by installing a reinforcing member in the site where the local cross-section collapse occurs It is to provide a door for the automobile reinforced with strength against side collisions.
본 발명 자동차용 도어는 측면충돌이 일어날 때에 최대 굽힘모멘트가 작용하는 부분에 하나 이상의 보강부재를 측면충돌의 하중이 작용하는 방향으로 설치한 안전빔을 브라켓을 통하여 외판에 장착한다.According to the present invention, a door for a vehicle includes a safety beam mounted on an outer plate through a bracket having one or more reinforcing members installed in a direction in which a load of a side collision is applied to a portion at which a maximum bending moment acts when a side collision occurs.
상기한 보강부재는 머리붙이핀 형상으로 형성되고 상기한 안전빔에 형성된 삽입구멍에 삽입한 다음, 리벳작업을 행하고 용접 등에 의하여 상기한 안전빔에 일체로 설치된다.The reinforcing member is formed in the shape of a hairpin pin and inserted into the insertion hole formed in the safety beam, and then is riveted and integrally installed in the safety beam by welding or the like.
상기와 같이 구성되는 본 발명 자동차용 도어는 측면충돌이 일어날 때에 안전빔에서 효과적으로 충격하중에 대응하므로 안전도가 향상된다. 즉 측면충돌이 일어날 때에 도어에 있어서 최대 굽힘모멘트가 작용하는 부분의 안전빔에 보강부재를 설치하였기 때문에 보다 큰 충격하중에도 안전빔의 강성을 유지하는 것이 가능하므로 자동차의 안전도가 향상된다.The vehicle door of the present invention configured as described above effectively copes with the impact load in the safety beam when a side collision occurs, thereby improving safety. That is, since the reinforcement member is installed in the safety beam of the part where the maximum bending moment acts on the door when the side collision occurs, it is possible to maintain the rigidity of the safety beam even under a greater impact load, thereby improving the safety of the vehicle.

다음으로 본 발명에 따른 자동차용 도어의 가장 바람직한 실시예를 도면을 참조하여 상세하게 설명한다.Next, the most preferred embodiment of the automobile door according to the present invention will be described in detail with reference to the drawings.
먼저 제1도∼제2도에 나타낸 바와 같이, 본 발명에 따른 자동차용 도어의 일실시예는 측면충돌이 일어날 때에 최대 굽힘모멘트가 작용하는 부분에 하나이상의 보강부재(14)를 측면충돌의 하중이 작용하는 방향 즉 국부단면붕괴가 발생하는 방향으로 설치한 안전빔(10)을 브라켓(4)을 통하여 외판(2)에 장착한다.First, as shown in Figs. 1 to 2, one embodiment of a door for a vehicle according to the present invention loads at least one reinforcing member 14 at a portion at which the maximum bending moment acts when a side collision occurs. The safety beam 10 provided in the direction in which this action acts, that is, the direction in which local cross-sectional collapse occurs, is mounted on the outer plate 2 via the bracket 4.
상기한 부강부재(14)는 머리붙이핀 형상으로 형성되고 상기한 안전빔(10)에 형성된 삽입구멍(12)에 삽입한 다음, 리벳작업을 행하고 용접 등에 의하여 상기한 안전빔(10)에 일체로 설치된다.The steel member 14 is formed in the shape of a hairpin pin and inserted into the insertion hole 12 formed in the safety beam 10, and then performed riveting and integrated into the safety beam 10 by welding or the like. Is installed.
상기한 보강부재(14)는 안전빔(10)을 지름방향으로 관통하도록 형성된다.The reinforcing member 14 is formed to penetrate the safety beam 10 in the radial direction.
상기한 실시예에서는 보강부재(14)를 최대 굽힘모멘트가 작용하는 중앙부에 하나 설치하는 것으로 설명하였지만, 보강부재(14)를 최대 굽힘모멘트가 작용하는 중앙부에 하나 절치하고 중앙부로부터 일정한 간격을 두고 복수의 보강부재(14)를 더 설치하는 것도 가능하다.In the above-described embodiment, the reinforcing member 14 has been described as having one installed at the central portion where the maximum bending moment acts. It is also possible to further install the reinforcing member (14).
상기와 같이 구성되는 본 발명 자동차용 도어는 측면충돌이 일어날 때에 안전빔(10)에서 효과적으로 충격하중에 대응하므로 안전도가 향상된다. 즉 측면충돌이 일어날 때에 안전빔(10)의 초대 굽힘모멘트가 작용하는 부분에 보강부재(14)를 설치하였기 때문에 보다 큰 충격하중에도 국부단면붕괴가 방지되어 안전빔(10)의 강성을 유지하는 것이 가능하므로 자동차의 안전도가 향상된다.The vehicle door of the present invention configured as described above effectively copes with the impact load in the safety beam 10 when a side collision occurs, thereby improving safety. That is, since the reinforcing member 14 is installed at the portion where the primary bending moment of the safety beam 10 acts when a side collision occurs, local cross-sectional collapse is prevented even under a larger impact load, thereby maintaining the rigidity of the safety beam 10. It is possible to improve the safety of the car.
상기에서는 본 발명의 바람직한 실시예에 대하여 설명하였지만, 본 발명은 이에 한정되는 것이 아니고 특허 청구의 범위와 발명의 상세한 설명 및 첨부한 도면의 범위 안에서 여러 가지로 변형하여 실시하는 것이 가능하고 이 또한 본 발명의 범위에 속하는 것은 당연하다.Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the scope of the invention.
상기와 같이 구성되는 본 발명 자동차용 도어에 의하면, 중량증가가 거의 없이 종래보다 국부단면붕괴에 대한 강도를 대략 4배 이상 높일 수 있으므로, 측면충돌에 대한 안전도가 크게 향상된다.According to the vehicle door of the present invention constituted as described above, since the strength against local cross-sectional collapse can be increased by approximately four times or more compared with the prior art with little increase in weight, the safety against side collisions is greatly improved.
또 안전빔의 측면충돌에 대한 강도가 크게 향상되므로 안전빔의 지름을 작게 형성하는 것이 가능하기 때문에 원가절감이 가능하고 차체의 중량을 줄일 수 있다.In addition, since the strength of the side impact of the safety beam is greatly improved, it is possible to form a smaller diameter of the safety beam, so that the cost can be reduced and the weight of the vehicle body can be reduced.
