Abstract
【解決手段】本発明に係る車両用バンパビーム構造は、複数の垂直面を一体に連結した断面形状を備えた金属材質のセンタビームと、前記センタビームの外側を覆う断面形状を備えたプラスチック材質のアウタビームと、前記アウタビームの外側に備えられた複数のリブと、を含んで構成されたことを特徴とする。
【選択図】図1
Description
例えば、特許文献1にはバンパビームとバンパ間に合成樹脂発泡体を介在させることにより、歩行者と搭乗者の安全を両立させる技術が開示されている。
図1に示すように、バンパビーム11は複数の垂直面1を一体に連結した断面形状を備えた金属材質のセンタビーム3と、センタビーム3の外側を覆う断面形状を備えたプラスチック材質のアウタビーム5と、アウタビーム5の外側に備えられた複数のリブ7とを含んで構成される。
リブ7は、隣接した2つの辺がアウタビーム5の隣接した2つの表面に連結される3角状に形成され、アウタビーム5の長手方向に沿って3角形の斜辺が互いに交差する形態で設けられている。
バンパビーム11は、センタビーム3とアウタビーム5とで担う全体的な強度が、従来の単純な平板を折り曲げた断面形状を有するバンパビームと概ね同じになるように形成される。
即ち、センタビーム3自体の強度は、従来のバンパビームに比べて多少弱く形成され、弱くなった強度はアウタビーム5が補うようになっている。
勿論、バンパビーム11の強度は、バンパビーム11が装着される車体19の前方部分よりは弱い強度から形成される。
特に、バンパビーム11の変形は、衝撃が加えられた変形初期にはプラスチック材質のアウタビーム5が破損されながら衝撃エネルギーを急速に吸収する作用をし、以後にはセンタビーム3がバンパビーム11の変形時間をできるだけ長く形成するようにする。
この時、アウタビーム5に形成されたリブ7は、センタビーム3を助けてバンパビーム11の変形時間を長くするのに寄与する。
