Abstract: A vehicle body frame structure, incudes: a left and right pair of side frames; a first cross member and a second cross member extending in a vehicle width direction and spanning between the side frames, at a vehicle front side of the side frames, being in this order from the vehicle front side; a center frame extending toward a vehicle rear side from a substantially central part, in the vehicle width direction, of the second cross member; and a stopper member provided at a substantially central part, in the vehicle width direction, of either one of the first cross member or the second cross member so as to be positioned between the first cross member and the second cross member in plan view, with a gap provided between the stopper member and another one of the first cross member or the second cross member.

Abstract: A vehicle lower portion structure includes a left and right pair of side frames, a battery pack, a cross member, and an energy absorption member. In a bottom view, a vehicle width direction outer side end portion of the cross member is bent toward a vehicle front-rear direction outer side, starting from a portion at which the vehicle width direction outer side end portion reaches the energy absorption member, and is attached to one of the side frames, and a vehicle front-rear direction outer side end portion of the energy absorption member is disposed along a face, of the vehicle width direction outer side end portion of the cross member, that faces toward a vehicle front-rear direction inner side. A reinforcing member is provided at a portion at which the cross member is bent.

Abstract: A vehicle lower section structure including a battery and an energy absorption member. The energy absorption member includes an upper wall, a lower wall, and plural upright partitioning walls that form plural spaces. The spaces along a vehicle width direction from an outermost space to a freely selected space of the spaces are provided alternately with either a pair of first indentations in a lower face of the upper wall indented toward a vehicle upper side of the space and in an upper face of the lower wall indented toward a vehicle lower side of the space, or a pair of second indentations in an upper face of the upper wall indented toward the vehicle lower side of the space and in a lower face of the lower wall indented toward the vehicle upper side of the space.

Abstract: A vehicle front portion structure includes: a motor unit disposed at a vehicle front part; a suspension member disposed at the vehicle front part, the suspension member extending in a vehicle front-rear direction and deforming toward a vehicle lower side at a time of vehicle frontal collision; a left-right pair of front side motor mounts connecting a front part of the motor unit with the suspension member; a rear side motor mount connecting a central part, in a vehicle width direction, of a rear part of the motor unit with the suspension member; and a break mechanism that causes the rear side motor mount, which moves toward a vehicle rear side at a time of vehicle frontal collision, to break in the vehicle width direction.

Abstract: A vehicle underbody structure capable of maintaining coupling between a brace and a floor frame against a load transmitted from the front side through the brace is provided, even without making a mechanical strength of a coupling portion between the brace and the floor frames particularly high. A brace is provided with a front-side coupling member and a rear-side coupling member, and the front-side coupling member and the rear-side coupling member are connected together by a load transmission section that is substantially M-shaped in plan view. The rear-side coupling member is connected to outside load transmission members of the load transmission section further to a left-right direction central side than a coupling portion of the rear-side coupling member to each floor frame. A load transmitted to the rear-side coupling member accordingly attempts to deform the rear-side coupling member about a rear end portion of the outside load transmission members.
