A vehicle battery pack frame for a vehicle comprising: a base having a length and a width; side members on opposite sides of the base, extending along the length of the base, and attached to a periphery of the base; and crossbeams extending across the width of the base, between the side members; wherein each of the side members comprises a profiled body comprising a sidewall having a first surface facing the cross beams, and an opposite second surface; and a polymer reinforcement attached to the profiled body and facing the second surface of the sidewall of the profiled body.

A frame structure for maintaining energy storage devices of a vehicle in position which is deformed in a controlled way in the event of a side-impact, in such a way to avoid deforming into the location of the vehicle seats. The proposed frame structure is adapted to deform controllably in a centre position align with a location between the vehicle seats. In this way are occupants of the vehicle kept safe since no or less deformation occur in the vehicle seat location. The above advantages are provided by that lateral support members of the frame includes a deformation zone adapted to deform in response to a lateral force exerted on the lateral support member. The deformation zone is located such that, when the frame structure is installed in the vehicle, the deformation zone is aligned with a location between seats of the vehicle.

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.

A body for a vehicle configured for securing safety performance and vehicle rigidity according to a vehicle collision while increasing a battery capacity mounted in the vehicle, may include an internal side member mounted on a center floor in a longitudinal direction of the body; a battery cross member mounted in a width direction of the body inside a battery case provided at a lower end portion of the center floor while intersecting the internal side member; and a coupling structure coupled to the battery case, the battery cross member, and the center floor.

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 vehicle body structure for reinforcing a pop-up seat mounting part includes a pair of rear side members engaged with a floor panel of a vehicle body, the pair of rear side members being spaced apart from each other by a spacing distance, a transverse member having a length corresponding to the spacing distance between the pair of rear side members, the transverse member being connected at opposite ends thereof to ends of upper surfaces of the pair of rear side members, and a back panel in contact with one surface of the transverse member.

A vehicle center frame module includes a pair of side sills, each side sill including a side sill inner having a closed cross section and a side sill outer having a closed cross section, wherein an inboard side surface of the side sill outer and an outboard side surface of the side sill inner are joined, and a plurality of crossmembers connecting the pair of side sills in a transverse direction of a vehicle, the crossmembers including a first crossmember and a second crossmember disposed behind the first crossmember in a longitudinal direction of the vehicle.

An embodiment vehicle intermediate structure includes a first intermediate crossmember connecting a pair of side sills in a width direction of a vehicle, wherein each end face of the first intermediate crossmember is attached to an inboard side surface of the corresponding side sill, and wherein a cross section of the first intermediate crossmember is uniform in a longitudinal direction thereof.

An embodiment rear side structure for a vehicle includes a rear side member extending in a longitudinal direction of the vehicle, a shock absorber mounting member connected to the rear side member, and a rear wheelhouse panel connected to the shock absorber mounting member, wherein the shock absorber mounting member and the rear wheelhouse panel are joined so that the shock absorber mounting member and the rear wheelhouse panel form a wheel arch.

An under body may include a side sill inside front panel bent similar to the side sill inside panel to connect a front end portion of the side sill inside panel with a dash panel to be bonded to each other; a front side member connecting member connected with a bottom surface of the dash panel and a rear end portion of a front side member while being bonded to an inside surface of the side sill inside front panel; a side sill inside rear panel configured to connect a rear end portion of the side sill inside panel with a rear side member to be bonded to each other; and a rear side member connecting member configured to connect a bottom end portion of the side sill inside rear panel with a front inside surface of a rear side member to be bonded to each other.
