A lower vehicle-body structure of an electric vehicle includes a bending facilitating portion located outward of a bent portion of a kick-up and bends as a breakage starter in a lateral collision, earlier than the bent portion, to reduce the amount of projection from the bending facilitating portion toward an outer side and reduce the likelihood of interference with a battery. Each of left and right side portions in a vehicle width direction of a kick-up is bent downward from a position inward of a rear side frame toward a side sill and connected to the side sill. A bending facilitating portion that facilitates bending under a lateral-collision load is formed outward of a bent portion of the kick-up and an outer side portion of the battery, and either inward of an inner end of the rear side frame or at substantially the same position as the inner end.

A battery case is joined to a rocker inner formed toward a vehicle width direction inner side of a rocker. The rocker is provided with rocker outer R/F and rocker inner R/F that respectively form a closed cross-section portion and a closed cross-section portion between themselves and a rocker panel that partitions a closed cross-section portion formed by a rocker outer and the rocker inner in the vehicle width direction.

A vehicle support structure according to an exemplary aspect of the present disclosure includes, among other things, a cross-member of a vehicle support structure. The cross-member extends longitudinally along a cross-member axis. The frame assembly further includes a rail of the vehicle support structure. The rail extends longitudinally along a rail axis that is transverse to the cross-member axis. The rail extends into a pocket of the cross-member such that a portion of the rail is nested within the cross-member.

An embodiment rear floor side member assembly includes a rear side member including a rear inner portion disposed toward an inside of a vehicle body, a rear upper portion curved toward an outside of the vehicle body from the rear inner portion, and a rear lower portion curved from the rear inner portion toward the outside of the vehicle body, a reinforcement mounting portion formed on the rear lower portion, a rear side member reinforcement mounted on the reinforcement mounting portion, and a rear spring seat assembly mounted at a bottom part of the rear side member reinforcement.

This vehicle body substructure includes side sill load transmitting members that are provided inside each of side sills, a floor cross-member that is provided on one of an upper surface and a lower surface of a floor panel laid between the side sills and has extending portions extending toward upper portions of the side sill load transmitting members, an underfloor mounting component that is provided below the floor panel and includes an underfloor cross-member, underfloor frames that are attached to lower portions of the underfloor mounting component and the side sills, and underfloor load transmitting members that are provided in the underfloor frames and face the underfloor cross-member. The underfloor load transmitting member has an upper half portion which faces a lower portion of the side sill load transmitting members, and a lower half portion which is fixed to a part of each of the underfloor frames attached to a lower portion of each of the side sills.

A vehicle body structure includes a body side section (1) configured of a first composite component (10) and a body lower section (2) configured of a second composite component (20). Each of the first and second composite components (10, 20) comprises a metal plate (11, 21) and a fiber reinforced thermoplastic portion (12, 22) that contains discontinuous fibers. The fiber reinforced thermoplastic portion (12) of the first composite component (10) includes a lining layer formed on the metal plate (11) and reinforcing ribs raised from the lining layer. The fiber reinforced thermoplastic portion (22) of the second composite component (20) includes a planar portion (24) infilled in an opening (23) opened on the metal plate 21. The discontinuous fibers in the fiber reinforced thermoplastic portion (22) of the second composite component (20) are longer than the discontinuous fibers in the fiber reinforced thermoplastic portion (12) of the first composite component (10).

Provided is a rear vehicle-body structure of a vehicle, capable of reducing vibrations transmitted from a rear wheel to a floor panel, while ensuring required performance for rear side frames and a cross member. The rear vehicle-body structure comprises a symmetric pair of frame members extending in a vehicle longitudinal direction along respective lateral sides of a rear of a vehicle body of the vehicle, and a rear-side rear cross member bridging the symmetric pair of frame members in a vehicle width direction, wherein an attachment portion between each of the frame members and the rear-side rear cross member provided with rigidity difference generation part to generate a rigidity difference between the frame member and the rear-side rear cross member.

A vehicle body lower structure may comprise: a rocker arranged at a lower lateral part of a vehicle body and extending along a front-rear direction of the vehicle body, the rocker being hollow; a power supply package arranged under a floor panel of the vehicle body; and an energy absorbing member fixed to the power supply package and fixed to a bottom plate of the rocker. A side surface of the energy absorbing member located under the rocker may be inclined to face diagonally upward, and a drain hole may be arranged in the bottom plate at a position above the side surface.

A vehicle body includes a plurality of shock absorber housings, each shock absorber housing adapted to cover and support a respective shock absorber connected to a respective wheel of a vehicle, wherein each of the shock absorber housings includes a projection projecting upwards from a lower end of the shock absorber housing with an internal space therein, wherein the lower end of the shock absorber housing or the projection is coupled to the shock absorber such that the shock absorber is disposed in the internal space in the projection.

A vehicle body includes a pair of side truss members extending in a longitudinal direction of a vehicle, a plurality of cross truss members connecting the pair of side truss members to each other in a width direction of the vehicle, a plurality of cross floor truss members coupled to upper ends of the pair of side truss members, extending in a transverse direction of the side truss members, and spaced apart from each other in an anteroposterior direction, and a plurality of side connection truss members extending in the longitudinal direction of the vehicle and connecting ends of the cross floor truss members to each other.
