Description
본 발명은 차량용 차체구조중 필라트림구조에 관한 것으로, 특히 충격 발생시 야기된 충격량을 효과적으로 흡수하여 충격흡수량을 개선시킨 충격흡수력이 향상된 차량용 필라트림구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar trim structure of a vehicle body structure, and more particularly, to a pillar pillar structure for a vehicle having improved shock absorbing power by effectively absorbing an impact amount caused when an impact occurs.
일반적으로 차량용 차체구조에서 필라트림구조는 승용차의 도어와 도어사이에 주로 설치되는 차체구조로서, 외부충격에 대하여 일정한 강성을 발휘하도록 되어 있는바, 이러한 필라트림의 종래구조를 살펴보면 도 3에 도시된 바와 같이 필라트림(101)의 안쪽 즉, 차실내쪽으로 횡방향으로 여러개의 리브(102)가 등간격으로 돌출형성되어 있다.In general, a pillar structure in a vehicle body structure is a vehicle structure mainly installed between a door and a door of a passenger car, and exhibits a certain rigidity against external impact. Referring to the conventional structure of the pillar structure, the pillar structure is illustrated in FIG. As described above, several ribs 102 protrude at equal intervals in the transverse direction toward the inside of the pillar trim 101, that is, the interior of the vehicle interior.
이러한 횡방향으로 형성된 여러개의 리브(102)들은 필라트림(101)의 바깥쪽에서 발생되는 충격을 흡수하도록 되어 있는데, 이 리브(102)의 형상이 평평한 단일의 판재형상으로 형성되어 있으므로 충격이 발생하게 되면, 충격흡수가 1차적으로 작용하게 되어 좌굴되기까지 짧은 시간으로 이루어짐에 따라 자연히 필라트림의 좌굴이 손쉽게 이루어지는 문제점이 있다. 예를 들어 도 4B에 도시된 그래프에서와 같이 충격력(F)에 대한 시간(t)의 진행이 짧게 설정되어 충격발생으로 인하여 상기 필라트림(101)의 리브(102)들이 뭉개짐에 따라 충분하게 충격흡수가 이루어지지 못하였다.The plurality of ribs 102 formed in the transverse direction are configured to absorb shocks generated from the outside of the pillar trim 101, and the ribs 102 are formed in a single flat plate shape so that the impacts are generated. In this case, the impact absorption is primarily acted as a short time until the buckling occurs naturally there is a problem that the buckling of the pillar trim easily occurs. For example, as shown in the graph shown in FIG. 4B, the progress of the time t with respect to the impact force F is set to be short, so that the ribs 102 of the filament 101 are crushed due to the impact. Shock absorption was not achieved.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 외부충격에 대하여 이를 충분하게 흡수분산시키어 강성을 향상시킨 개선된 충격흡수력이 향상된 차량용 필라트림 구조를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above-described conventional problems, and an object thereof is to provide an improved impact absorbing force for a vehicle pilar trim structure that is sufficiently absorbed and dispersed for external impact to improve rigidity.

3a : 연결단, 3b : 자유단.3a: connection end, 3b: free end.
상기와 같은 목적을 달성하기 위한 본 발명은 리브들이 횡방향의 등간격으로 형성된 필라트림에 있어서, 상기 각각의 리브는 상면이 계단진 형상으로 형성되되, 연결선단에서 자유단쪽으로 점차로 얇아지는 형상으로 형성되어 있다.In the present invention for achieving the above object, the ribs are formed at equal intervals in the transverse direction, each of the ribs is formed in a stepped shape of the upper surface, in a shape that gradually becomes thinner toward the free end from the connecting end Formed.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명이 적용된 필라트림(1)의 부분사시도이고, 도 2는 도 1의 I-I선 단면도이다.1 is a partial perspective view of a pillar trim 1 to which the present invention is applied, and FIG. 2 is a cross-sectional view taken along line II of FIG. 1.
도면에 도시된 바와 같이 안쪽면쪽으로 리브(2)들이 횡방향의 등간격으로 형성된 필라트림(1)에 있어서, 상기 각각의 리브(2)는 상면쪽이 계단진 형상으로 형성되되, 연결단(3a)에서 자유단(3b)쪽으로 점차로 얇아지는 구조로 되어 있다.In the pillar trim 1 having ribs 2 formed at equal intervals in the transverse direction toward the inner surface as shown in the drawing, each of the ribs 2 is formed in a stepped shape with an upper surface side, It becomes a structure which becomes thin gradually toward the free end 3b in 3a).
그리고 도면에는 도시하지 않았지만, 리브(2)의 계단진 형상은 필요에 따라 여러단계로 계단지게 형성할 수도 있음을 미리 밝혀둔다.And although not shown in the figure, it is noted that the stepped shape of the ribs 2 may be formed stepwise in several steps as necessary.
이와 같이 필라트림(1)의 안쪽면에 형성되는 리브들(2)이 계단진 형상을 갖게 됨으로써 충격에 대한 힘을 효과적으로 흡수할 수 있는바, 즉 필라트림(1)의 바깥쪽면에서 충격력이 작용할때 리브(2)의 연결단(3a)에서 일차적으로 충격을 흡수하여 좌굴된 다음, 이 리브(2)의 연속적인 자유단(3b)에서 일차적으로 흡수된 충격력을 이차적으로 흡수함에 따라 최초 충격에서 이 리브(2)들이 좌굴되기까지 걸리는 시간을 증가시키어 상기 리브(2)에 가해지는 충격력을 감소시킬 수 있는데, 이는 일반적으로 충격량이 동일할때 충격시간이 증가하게 되면 가해지는 힘이 감소되는 현상에 의하여 이루어지게 되는 것이다.In this way, the ribs 2 formed on the inner surface of the pillar trim 1 have a stepped shape so that they can effectively absorb the force against impact, that is, the impact force acts on the outer surface of the pillar pillar 1. At the connecting end (3a) of the rib (2) is first absorbed by the impact and buckled, and then secondarily absorbs the impact force absorbed primarily at the continuous free end (3b) of the rib (2) By increasing the time it takes for the ribs 2 to buckling, the impact force applied to the ribs 2 can be reduced. Generally, the force applied decreases when the impact time increases at the same amount of impact. It will be done by.
I = ∫F·dt … ①I = ∫F · dt... ①
예를 들어 ①식에서와 같이 전달되는 힘(I)은 충격력(F)과 시간(dt)에 의존하게 되는데, 시간(dt)이 증가하게 되면 충격력(F)은 작아지는 현상에 기인하기 때문이다.For example, ① the force (I) transmitted as in the equation depends on the impact force (F) and the time (dt), because the increase in time (dt) is due to the phenomenon that the impact force (F) becomes smaller.
이와 같이 본 발명은 도 4A에 도시된 그래프와 같이 좌굴시간(dt)을 증가시키어 충격력(F)이 종래 구조(도 4B)의 충격력(F)보다 작아지도록 되어 있다.As described above, the present invention increases the buckling time dt as shown in the graph shown in FIG. 4A so that the impact force F becomes smaller than the impact force F of the conventional structure (FIG. 4B).
상기와 같이 본 발명에 따른 필라트림구조는 계단진 리브들에 의하여 야기된 충격력을 분산흡수하여 충격흡수량을 증대시킴에 따라 필라트림의 강성이 향상되는 효과를 지니게 된다.As described above, the pillar structure according to the present invention has an effect of increasing the impact absorption amount by dissipating the impact force caused by the stepped ribs, thereby increasing the rigidity of the pillar portion.
