Description
ロアアブソーバは、前方からの衝撃を吸収するため、ある程度車両前後方向の寸法を有している必要がある。しかし、フロントバンパの意匠上の制約によって、フロントバンパの裏面から車体構造部材までの空間、すなわちロアアブソーバが配置される空間の車両前後方向の寸法が、車幅方向の位置によっては十分に確保できない場合がある。このような場合であっても、上記構成によれば、車幅方向に隣接した別体の第１のアブソーバと第２のアブソーバとでロアアブソーバを形成したので、第１のアブソーバおよび第２のアブソーバの車両前後方向の寸法や剛性をそれぞれ別々に調整することで、衝撃を十分に吸収でき、歩行者の脚部の保護性能を確保できる。 The lower absorber needs to have some size in the vehicle front-rear direction in order to absorb the impact from the front. However, due to restrictions on the design of the front bumper, the size in the vehicle front-rear direction of the space from the rear surface of the front bumper to the vehicle body structural member, that is, the space where the lower absorber is disposed, cannot be sufficiently secured depending on the position in the vehicle width direction. There is a case. Even in such a case, according to the above configuration, since the lower absorber is formed by the separate first absorber and second absorber adjacent in the vehicle width direction, the first absorber and the second absorber By separately adjusting the size and rigidity of the absorber in the longitudinal direction of the vehicle , the impact can be sufficiently absorbed and the protection performance of the pedestrian's legs can be secured.
例えば図４に示す領域１４６、１４８では、外側アブソーバ１１６、内側アブソーバ１１８およびベースブラケットの３つの部材が互いに重ねられ接合されることで、ロアアブソーバ１０８が車体構造部材に強固に取付けられている。なお領域１４６、１４８以外においては、ベースブラケット１４４は、外側アブソーバ１１６に主に接合されている。 For example, in the regions 146 and 148 shown in FIG. 4, the lower absorber 108 is firmly attached to the vehicle body structural member by overlapping and joining the three members of the outer absorber 116, the inner absorber 118 and the base bracket. In addition to the areas 146 and 148, the base bracket 144 is mainly joined to the outer absorber 116.
このように車体前部構造１００では、車幅方向に隣接した別体の外側アブソーバ１１６と内側アブソーバ１１８とでロアアブソーバ１０８を形成し、内側アブソーバ１１８および外側アブソーバ１１６の車両前後方向の寸法や剛性をそれぞれ別々に調整している。したがって車体前部構造１００によれば、フロントバンパ１０２の意匠上の制約がある場合であっても、ロアアブソーバ１０８が十分な衝撃吸収性能を確保できる。 In this way the vehicle body front structure 100, the lower absorber 108 is formed in the outer absorber 116 and the inner absorber 118 of the separate adjacent to a vehicle width direction, the vehicle front-rear dimension and rigidity of the inner absorber 118 and the outer absorber 116 Are adjusted separately. Therefore, according to the vehicle body front structure 100, the lower absorber 108 can ensure sufficient shock absorption performance even when there is a design limitation of the front bumper 102.
