The present invention relates to a battery pack structure which is provided with a rib material arranged between side walls in a battery case, so that the rigidity of the battery case itself can be improved compared with the case in which the rib material is not provided. Furthermore, when a side collision of the vehicle occurs, a side collision load input to the rocker is transmitted to the battery case side via the coupling part. The coupling portion is provided on an extension line of the rib in the vehicle width direction when the vehicle is viewed in plan, so that a side impact load transmitted to the battery case side via the coupling portion is transmitted from one side wall side to the rib, and is transmitted to the other side wall side.
本发明涉及一种蓄电池组结构,其通过在蓄电池壳体内设置有架设在侧壁之间的肋材,从而与未设置有该肋材的情况相比,能够提升蓄电池壳体本身的刚性。此外,在发生车辆的侧面碰撞时,被输入至下边梁上的侧面碰撞载荷会经由结合部而向蓄电池壳体侧被传递。由于该结合部在俯视观察车辆时被设置在肋材的车辆宽度方向的延长线上,因此经由结合部而向蓄电池壳体侧被传递过来的侧面碰撞载荷会从一方的侧壁侧而被传递至肋材上,并向另一方的侧壁侧被传递。
