４辺形の断面構造を持つ衝撃吸収構造体は、角部の剛性が他の部分に比べて高くなっている。
このために、衝撃吸収構造体が変形する際に、この角部の塑性変形抵抗が大きくなり、求められる衝撃吸収特性が得られないことがある。
本発明の目的は、衝撃吸収特性を改良した衝撃吸収構造体を提供するものである。 The shock absorbing structure having a quadrilateral cross-sectional structure has a higher corner rigidity than the other parts.
For this reason, when the shock absorbing structure is deformed, the plastic deformation resistance of the corner portion is increased, and the required shock absorbing characteristics may not be obtained.
An object of the present invention is to provide an impact absorbing structure having improved impact absorbing characteristics.

上記目的を達成するために、本発明の衝撃吸収構造体は、基本的な手段として、中空の４辺形の断面形状を有する４角柱状の構造を備え、４角柱の角部の稜線近傍の剛性は他の部分の剛性より低く設定されてなるものである。   In order to achieve the above object, the shock absorbing structure of the present invention has a quadrangular prismatic structure having a hollow quadrangular cross-sectional shape as a basic means, and is provided in the vicinity of the ridgeline at the corner of the quadrangular prism. The rigidity is set lower than the rigidity of other parts.

本発明の衝撃吸収構造体は、角部の稜線近傍の剛性を低下させてあるので、衝撃吸収特性が向上する。   Since the shock absorbing structure of the present invention has reduced rigidity in the vicinity of the corner ridgeline, the shock absorbing characteristics are improved.

以下、本発明の衝撃吸収構造体の実施例を説明する。   Examples of the shock absorbing structure of the present invention will be described below.

図１、図２は、本発明の第１の実施例を示す説明図である。
全体を符号２００で示す衝撃吸収構造体は、中空の４辺形の断面形状を有し、長さ寸法Ｌ１を有する４角柱状の部材である。
衝撃吸収構造体２００は、中空形材でつくられ、中空形材は、外板２１０と、内板２２０がトラス２３０で連結された構造を有する。すなわち、外板２１０と内板２２０とトラス２３０で囲まれる空間Ｒ１が連結される構造となっている。 1 and 2 are explanatory views showing a first embodiment of the present invention.
Shock absorbing structure generally indicated at 200, it has a hollow quadrilateral cross-sectional shape, a quadrangular prism-shaped member having a length dimension L 1.
The shock absorbing structure 200 is made of a hollow shape, and the hollow shape has a structure in which an outer plate 210 and an inner plate 220 are connected by a truss 230. That is, the space R 1 surrounded by the outer plate 210, the inner plate 220, and the truss 230 is connected.

中空形材は、互いに直交した状態で溶接等の接合手段Ｗ１より接合され、外板２１０が直交する外角部２４０と内板２２０が直交する内角部２４２が形成される。
本発明の衝撃吸収構造体２００にあっては、中空形材の外角部２４０と内角部２４２を結ぶ線Ｔ１に存在すべきトラスを省略した構造を有する。
すなわち、角部に形成される空間Ｒ２は、他の部分の空間Ｒ１に比べてほぼ２倍の容量をもつこととなる。
この構造を採用することにより、衝撃吸収構造体２００の角部の塑性変形抵抗が低下し、変形特性が変化する。 The hollow shape members are joined from joining means W 1 of the welding in a state of being perpendicular to each other, the interior angle portion 242 outer plate 210 is the inner plate 220 is orthogonal to the outer corner portion 240 perpendicular is formed.
The shock absorbing structure 200 of the present invention has a structure in which the truss that should be present on the line T 1 connecting the outer corner portion 240 and the inner corner portion 242 of the hollow shape member is omitted.
That is, the space R 2 which is formed at the corner portion becomes to have nearly twice the amount as compared to the space R 1 in other portions.
By adopting this structure, the plastic deformation resistance at the corners of the shock absorbing structure 200 is lowered, and the deformation characteristics are changed.

図３は、横軸に衝撃吸収構造体の変形量Ｄを、たて軸に衝撃荷重をとったカーブである斜線で囲まれる部分が衝撃吸収エネルギーを示す。
カーブＣ１は、従来構造の衝撃吸収構造体の特性を示し、カーブＣ２は、本発明の構造の衝撃吸収構造体の特性を示す。
この特性カーブに示されるように、本発明の衝撃吸収構造体にあっては、変形特性が向上し、吸収される衝撃エネルギーの総量も大きくすることができる。 FIG. 3 shows the shock absorption energy in a portion surrounded by a diagonal line, which is a curve in which the horizontal axis represents the deformation amount D of the shock absorbing structure and the vertical axis represents the impact load.
Curve C 1 shows the characteristics of the shock absorbing structure of the conventional structure, the curve C 2 shows the characteristics of the shock absorbing structure of the structure of the present invention.
As shown by this characteristic curve, in the shock absorbing structure of the present invention, the deformation characteristics are improved and the total amount of shock energy absorbed can be increased.

本構造によれば、中空形材の外角部２４０と内角部２４２を結ぶ線Ｔ１に存在すべきトラスを省略することにより、角部の空間Ｒ２の容量が大きくなる。したがって、前記角部の塑性変形抵抗が低下することにより図３の荷重Ｆのピークを低く抑えることができる。このことは、従来の構造によれば、角部のトラス部が荷重Ｆを受けて変形を開始するが、該角部のトラス部が座屈を始めると極端にその部分の剛性が低下する。 According to this structure, by omitting the truss to be on line T 1 connecting the outer corner portion 240 and the interior angle portion 242 of the hollow shape member, the volume of the space R 2 of the corner portion is increased. Therefore, the peak of the load F in FIG. 3 can be kept low by reducing the plastic deformation resistance of the corner. This is because, according to the conventional structure, the truss portion of the corner portion starts to deform under the load F, but when the truss portion of the corner portion starts buckling, the rigidity of the portion extremely decreases.

一方、本実施例の場合、前記角部の空間Ｒ２周囲は、他部分部に対して、従来構造よりも剛性の差が小さく、荷重下のピークを低く抑えることができる。また、本実施例の場合、角部の空間Ｒ２周囲と他の部分とが、従来構造に比べて、同期して変形が進むので、図３で示す衝撃吸収エネルギーを増大させることができる。
前記荷重Ｆのピークを低く抑えることにより、乗客の衝撃が減少することから、従来構造に比べて、本実施例の構造は、衝撃吸収性能を向上できる。 On the other hand, in the present embodiment, the space R 2 around the corner, to the other part section, small difference in rigidity than the conventional structure, it is possible to suppress the peak under load. Further, in the present embodiment, the space R 2 around the other portions of the corners, as compared with the conventional structure, the deformation in synchronization progresses, it is possible to increase the impact absorption energy shown in FIG.
Since the impact of passengers is reduced by keeping the peak of the load F low, the structure of this embodiment can improve the impact absorption performance compared to the conventional structure.
