A vehicle-body structure increases comfort inside a vehicle cabin and improves vehicle-body stiffness. A battery housing portion in which a battery is housed and a battery non-housing portion in which the battery is not housed are provided alongside in a vehicle front-rear direction below the vehicle cabin. A second frame portion disposed at the battery non-housing portion is larger than a first frame portion disposed at the battery housing portion in a vehicle width direction.

An electric-vehicle-body structure includes a floor panel constituting a floor of an occupant space, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space, extending in a front-rear direction, and including a bend portion at an intermediate portion, and a connecting member connecting the bend portion to the floor panel.

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.

A structural assembly includes a frame and a plurality of panels. The frame includes a wall that at least partially defines an interior region. The plurality of panels is disposed at least partially in the interior region and is coupled to the frame. The plurality of panels includes a first panel and a second panel. The first panel includes a first surface and a second surface opposite the first surface. The first surface defines a first plurality of depressions and the second surface defines a first plurality of protrusions complementary to the first plurality of depressions. The second panel includes a third surface and a fourth surface opposite the third surface. The third surface defines a second plurality of depressions. The fourth surface defines a second plurality of protrusions complementary to the first plurality of depressions. The first panel is coupled to the second panel.

Provided is a structure of the floor of a vehicle having a battery pack mounted on the lower side of the floor, the structure including a floor panel constituting the floor; a floor tunnel extending in the front-rear direction of the vehicle on the middle portion of the floor panel; a lower dash panel disposed in front of the floor panel and the floor tunnel; and an electromagnetic wave shielding panel covering a corner where the floor panel, the floor tunnel, and the lower dash panel are connected to each other.

An exemplary approach for protecting floorings in containers may utilize a first ledger attached to an upper portion of a first support beam associated with a foundational base assembly. A portion of the first ledger may protrude outward in a first horizontal direction from the upper portion of the first support beam. A second ledger may be attached to an upper portion of a second support beam next to the first support beam. A portion of the second ledger may protrude outward in a second horizontal direction from the upper portion of the second support beam. The second horizontal direction may face the first horizontal direction. A support panel may be placed on top of the portion of the first ledger and the portion of the second ledger. The support panel may have a length proximate to a distance between the first support beam and the second support beam.

A composite floor is provided comprising a skeletal framework, foam core inserts, an impact resistant sheet, and a weather resistant sheet bonded together with adhesive. Recreational vehicles incorporating such floors are also contemplated, as are methods of making the composite floor.

An energy absorbing strut having, a first end coupled with an inner cylinder, and a second end connected with a hollow rod extending within the inner cylinder. A piston is carried by the rod having an outer surface sealing against an inside diameter of the inner cylinder and forming a compression chamber and a rebound chamber bounded by the piston, the rod having an internal passageway communicating between the compression chamber and the rebound chamber. An inertial mass carried by the rod movable axially on the rod between a closed position against and annular rod passageway and an open position opening the rod passageway and allowing the flow of a hydraulic fluid between the compression chamber and the rebound chamber. A spring acts on the inertial mass biasing the inertial mass toward the closed position. The energy absorbing strut may be used in a blast mitigation system for a military vehicle or other applications for providing shock isolation between two structures.

A body for a vehicle includes a first member provided at a lower portion of a front floor module extending to a front of a second member provided at a center floor module, and a third member provided at a lower portion of a rear floor module extending to a rear of the second member provided at the center floor module to form a main load path along the first, second, and third members extending from a foremost end of the vehicle to a hindmost end of the vehicle.

A total of four anchor points (5fl, 5fr, 5rl, and 5rr) are provided at front positions and rear positions of a left side member and a right side member (31 and 3r) provided on a floor (2). A drive motor (9), an inverter (10), and a transaxle (11), which serve as a drive unit (8), are mounted on the rear suspension cross member (4) supportively suspended from the respective anchor points. A junction box (21), a charger (22), and a DC-AC inverter (23), which serve as a power supply unit (20), are attached to the upper side of the floor (2). The junction box (21) relays electric power to supply it to the inverter (10). On the upper surface of the floor (2), an upper front floor cross member (16) is provided between the anchor points at the front position, and an upper rear floor cross member (17) is provided between the anchor points at the rear position. The power supply unit (20) is disposed between the members (16, 17).
