Description

자동차 도어 하단부 강성보강구조Steel door at bottom of steel door

본 발명은 자동차의 측면충돌시 도어의 파손과 도어의 실내 침입을 최소화하여 승객을 보호하는데 목적을 둔 도어 하단부 강성 보강구조에 관한 발명이다.The present invention relates to a door lower end rigidity reinforcing structure aimed at protecting a passenger by minimizing the breakage of a door and the intrusion of a door at the time of side collision of an automobile.

차량의 측면 충돌시에 강성보강구조가 미약한 도어 일수록 크게 파손될 뿐만 아니라 도어가 실내로 밀려들어오면서 승객이 크게 부상하는 문제점이 있게 되는 것이다.A door with a weak steel structure at the time of a side collision of the vehicle is greatly damaged as well as a problem that a passenger is greatly injured due to the door being pushed into the room.

이와같은 문제점을 줄이기 위한 기술적 수단으로 도어 아웃트패널의 내면에 보강맴버나 파이프 빔을 보강하는 수단이 알려지고 있는 것이다.As a technical means for reducing such a problem, a means for reinforcing a reinforcing member or a pipe beam on the inner surface of the door outer panel is known.

도 3 에 표시된 종래 기술의 도어 보강수단을 보면 아웃트패널(1)과 인너패널(2)로 구성되고 그 사이에 공간(h)이 형성되는 도어(d)의 아웃트패널(1) 내면 상하부에 철판을 절곡 구성한 보강맴버(3)와 파이프빔(4)을 장착하여 강성보강을 향상시키고 있으나 만족할 만한 효과를 얻을 수가 없었던 것이다.3 shows the door reinforcing means of the prior art shown in Fig. 3, in which the door d is composed of an outer panel 1 and an inner panel 2 and a space h is formed therebetween, The reinforcement member 3 and the pipe beam 4, which are formed by bending the steel plate, are mounted on the steel plate 1, thereby improving the rigidity reinforcement.

사실상 도어의 구조는 도어 아웃트패널(1)과 도어 인너패널(2) 사이에 도어 글라스의 구동에 장애가 되지 않는 도어 하부에 상당한 면적의 공간이 형성되어 있고 이 공간을 이용한 강성 보강구조가 절실한 실정이나 지금까지는 특별한 대안이 없는 실정인 것이다.In fact, the structure of the door is such that a considerable area of space is formed between the door outer panel 1 and the door inner panel 2 at the lower portion of the door which does not hinder the driving of the door glass, Until now, there is no special alternative.

그 이유는 도어의 아웃트패널과 인너패널 사이의 공간에 강성 보강구조를 구비시키면 도어 자체 중량이 크게 늘어나는 문제점이 있게 되는 것이다.The reason is that if the rigid reinforcing structure is provided in the space between the outer panel and the inner panel of the door, the weight of the door itself increases greatly.

이와같은 문제점을 해결하기 위해서는 강성보강구조를 효과적으로 장착시킬 수 있는 기술적 수단과 경량부재의 사용 등이 문제점으로 남아있게되며 이와같은 문제점을 효과적으로 해결할 수가 있다면 만족할 만한 강성보강구조를 얻을수가 있게 되는 것이다.In order to solve such a problem, technical means and a lightweight member capable of effectively mounting a rigid-frame steel structure remain as problems, and if such a problem can be effectively solved, a satisfactory rigid frame steel structure can be obtained.

본 발명은 상기한 문제점을 해결하기 위하여 도어의 하부 공간내에 강성향상과 충격완화 및 충격흡수가 뛰어난 구조를 내장시켜 도어의 하부강성이 크게 보강되도록 하는 것이다.In order to solve the above-mentioned problems, the present invention intends to reinforce the lower rigidity of the door by incorporating a structure having improved rigidity, shock-absorbing and shock absorption in the lower space of the door.

본 발명의 보강구조는 도어 하부에 기존 설치되어 있는 임팩트 빔의 설치부위를 보강하고 공간을 활용한 보강부재와 경량재의 충격완화부재 및 충격흡수부재 등을 효과적으로 내장 설치하므로서 도어 하부의 강성이 크게 보강될 수 있게 한 것이다.The reinforcement structure of the present invention reinforces the existing installation part of the impact beam at the lower part of the door and effectively reinforces the rigidity of the lower part of the door by effectively installing the reinforcing member utilizing the space and the impact absorbing member and the impact absorbing member of the lightweight material. .
