A vehicle-body front structure includes a partition wall portion which demarcates a space inside a vehicle cabin and a pair of left and right suspension tower portions which are formed to bulge inward in the vehicle width direction and support upper portions of front suspension apparatuses. A lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position. A traveling motor is installed below the lower-side portion of the partition wall portion. An upper-side portion of the partition wall portion extends from an intermediate portion of the left suspension tower portion in a vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

Vehicle-body front structure

Both of a requirement for absorption of an impact load in a collision and a requirement for layout of direction and position of a steering wheel are satisfied based on a vehicle-body front structure that includes a partition wall portion which demarcates a vehicle cabin inside space. A lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position. A traveling motor is installed below the lower-side portion of the partition wall portion. A recess portion which is recessed toward vehicle front is formed in a portion, on an upper side of the traveling motor, in the partition wall portion. An inserting hole through which a steering shaft is inserted is formed in a lower wall portion of the recess portion.

A vehicle-body structure comprises right-and-left front side frames and right-and-left frame members respectively extending forward from a vehicle-front portion of a battery case below the right-and-left front side frames. Plural right-side connection portions to connect the right-side frame member to the right-side front side frame are provided to be spaced apart from each other in a vehicle longitudinal direction.

Vehicle-body structure of electric automotive vehicle

To increase the stiffness of a floor panel while maintaining a large foot space for a rear-seat passenger. A vehicle-body structure includes a floor panel constituting a floor provided with front-row and rear-row seats, and a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion and extending in a vehicle front-rear direction. A recessed portion having a bottom surface on which the feet of a passenger sitting on the rear-row seat can be placed is formed at the floor panel. The floor panel includes a cross member extending in a vehicle width direction at a rear portion of the recessed portion. A rear portion of the center frame is connected to the cross member.

Vehicle-body structure including a cross member at a recessed portion of the floor panel

A vehicle-body structure comprises a dash panel, a pair of right-and-left front side frames, a pair of right-and-left side sills, a pair of right-and-left first longitudinal load-transmitting members respectively extending from respective vehicle-rear portions of the right-and-left front side frames to the right-and-left side sills along an upper face of the floor panel, and a pair of right-and-left second longitudinal load-transmitting members respectively extending from the respective vehicle-rear portions of the right-and-left front side frames toward a vehicle-front portion of the battery case along a lower face of the floor panel.

A floor panel comprises a first floor portion and a second floor portion which is located at a higher level than the first floor portion. In a vehicle-body structure, a connecting member which extends from a battery case to a second floor portion and connects the battery case and the second floor portion is provided.

A vehicle-body structure of an electric automotive vehicle comprises floor-side cross members attached to a floor panel and extending in a vehicle width direction along the floor panel and battery-side cross members provided at a battery case and extending in the vehicle width direction. The floor-side cross members and the battery-side cross members are offset from each other in a vehicle longitudinal direction in a vehicle side view.

A bulge portion bulging rearward is provided at a dash panel. A reinforcement is fixed to an inner surface of the bulge portion. A rear end wall portion of the bulge portion is positioned at the rear of a center portion of a rear end portion of a cowl panel in a vehicle width direction.

Vehicle body structure

A vehicle structure includes side sills, pillars, a first battery arrangement portion provided inside the vicinity of the pillars in a vehicle width direction below a floor panel, and a second battery arrangement portion provided at a center portion in the vehicle width direction below the floor panel in a region inside an outer portion of the first battery arrangement portion in the vehicle width direction.

A vehicle body structure includes a front floor panel provided on a vehicle front side and a rear floor panel provided at the rear of the front floor panel. The front floor panel is positioned higher than the rear floor panel. A first battery arrangement portion is provided long in a vehicle front-rear direction at a center portion of the front floor panel in the vehicle width direction. A second battery arrangement portion is provided outside the first battery arrangement portion in a vehicle width direction below the front floor panel. An upper portion of the first battery arrangement portion is positioned higher than an upper portion of the second battery arrangement portion.

A vehicle body structure includes a front floor panel and a rear floor panel provided at the rear of the front floor panel. The front floor panel is positioned higher than the rear floor panel. A front battery that supplies electric power to the traction motor is arranged below the front floor panel.

A side load-transmitting member extending in a vehicle longitudinal direction and transmitting a load applied to a vehicle-inward side from a vehicle-outward side toward the vehicle-inward side is provided inside a side sill. A lower portion of the side sill is provided to overlap a battery case in a vehicle side view. The side load-transmitting member comprises a first vertical wall portion provided to overlap a floor-side cross member in the vehicle side view and a second vertical wall portion provided to overlap the battery case in the vehicle side view.

The vehicle body structure includes a front floor panel, a rear floor panel positioned lower than the front floor panel, and a connection panel extending from a rear portion of the front floor panel to a front portion of the rear floor panel and inclined or curved so as to be positioned downward toward a rear side. At least the front portion of the connection panel is positioned at the front of the front portion of the front seat.

An impact absorbing member structure of a vehicle includes: a pair of left and right rear side frames; a pair of left and right crash cans containing a plurality of first carbon fibers arranged so as to continuously extend in a forward/rearward direction; and a bumper reinforcement attached to tip end portions of the pair of rear side frames through the pair of crash cans. Each of the crash cans is formed as an open-section member including: a side wall portion extending in the forward/rearward direction; and a tip end wall portion continuous with the side wall portion and including an attaching portion to which the bumper reinforcement is attached.

Impact absorbing member structure of vehicle

An impact absorbing structure includes an impact absorbing member made of CFRP, and the impact absorbing member includes a pair of left and right side wall portions and upper and lower coupling wall portions each coupling the side wall portions. Each of the pair of side wall portions includes a plurality of curved portions. Each of the curved portions is formed such that a leftward/rightward direction depth thereof decreases toward a front side. Each of the pair of side wall portions includes: a plurality of first carbon fibers arranged to extend in a forward/rearward direction and constituting most of reinforced fibers contained in the side wall portion; and a plurality of second carbon fibers arranged to extend in a direction intersecting with the first carbon fibers. The plurality of second carbon fibers are arranged at both thickness direction end vicinity parts of each of the side wall portions.
