A floor assembly for an electrically operable motor vehicle includes a vehicle floor, which runs on top of an energy storage device for driving the vehicle, has at least one floor element, and to which a side sill is attached on each outer side. In order to ensure that the energy storage device below the vehicle floor is protected against excessive damage in the event of a crash, in particular a side-impact crash, a first, outer, deformation zone of the floor assembly is provided in the region of the side sills, with the energy storage device being arranged at a distance from the first, outer deformation zone in the transverse direction of the vehicle so as to form a second, inner, deformation zone. The first, outer, deformation zone is deformable under a lower load level than the second, inner, deformation zone.

A sill frame arrangement for a vehicle body arrangement includes: a battery arrangement provided in a floor region of the vehicle body arrangement, which has at least one frame arrangement having frame longitudinal members and frame cross members which surround and support at least one battery module, the frame longitudinal members resting on sill elements of a sill arrangement, the sill arrangement including wall elements which form sill chambers. Over an entire height of the sill arrangement, only one wall element directed toward the frame arrangement is provided, at least one additional sill element being provided on each sill element, the sill element and the at least one additional sill element being integrally bonded and interlockingly connected to one another.

A lower vehicle-body structure includes: side sills extending along a vehicle front-rear direction and provided on both sides in a vehicle width direction of a vehicle body, respectively; a front undercover covering a lower surface of the vehicle body and having a first flange which extends to an outer bottom surface of each of the side sills; and a side sill garnish having a second flange covering the outer bottom surface from outside in the vehicle width direction. The first flange and the second flange are overlapped with each other in a vehicle up-down direction, and are fastened together to the outer bottom surface of the side sill.

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.

An entrance is provided in a side surface of a body of a vehicle. A side portion of the entrance in the width direction is constituted by a first frame member extending in the vehicle up-down direction. A lower end portion of the entrance is constituted by a floor extension portion of a floor member disposed on the inner side of the entrance with respect to the first frame member. The entrance is provided with a joint member. The joint member extends from the floor extension portion of the floor member to the first frame member, and closes a gap provided between the floor member and the first frame member. Thus, it is possible to suppress wind, rain, noise, etc. from entering a vehicle cabin through the gap.

A vehicle body may include a floor; a pair of side sills connected to first and second side edges of the floor, respectively; and a cross unit mounted on the floor and extending in a width direction of a vehicle, wherein the cross unit includes a lower crossmember connecting the pair of side sills, an upper crossmember disposed above the lower crossmember, a first reinforcement member disposed between the lower crossmember and the upper crossmember, and a pair of second reinforcement members connected to first and second end portions of the first reinforcement member, respectively.

An embodiment floor connection structure of a vehicle under body configured to connect a floor panel to side sills on both sides of the under body includes a plurality of box panels, each of the box panels including an opened portion and a closed portion, wherein the box panels are configured to be connected to each other along a vehicle width direction, and wherein a first box panel is coupled to a first side sill through the opened portion of the first box panel and a second box panel is coupled to a second side sill through the opened portion of the second box panel.

A body structure for an electrically operated vehicle, having an installation space for a traction battery, which space is open toward the vehicle bottom in the vertical vehicle direction, is delimited toward the vehicle top by a floor pan part that forms the vehicle floor, and is delimited on both sides in the transverse vehicle direction by a rocker panel that delimits a side-door opening toward the vehicle bottom, wherein a front body longitudinal member that transitions into the respective rocker panel toward the rear of the vehicle in the longitudinal vehicle direction extends on each vehicle side in the front-end region, and wherein the relevant front corner of the traction battery is enclosed by an interior corner region, in particular right-angled interior corner region, that stretches between the rocker panel and the front battery cross member.

A structural assembly for a vehicle includes a battery structure having a battery frame. The structural assembly includes a vehicle frame and a vehicle body. The vehicle frame has opposed longitudinal rails. The vehicle body is separate from and mounted on the vehicle frame. The vehicle body includes opposed rockers extending in a longitudinal direction of the vehicle. Each opposed longitudinal rail is located between a respective rocker and the battery frame of the battery structure.

A vehicle front structure includes: a pair of left and right front pillars; a front wall portion provided between the pair of left and right front pillars and forming a front end of the vehicle interior; a lower wall portion extending rearward from a lower end of the front wall portion; a tunnel member formed at a middle portion of the lower wall portion in a vehicle width direction and having an upward convex shape; and a reinforcing portion laminated on and fixed to the front wall portion or the front wall portion and the lower wall portion, in which the reinforcing portion is provided so as to be inclined downward from the front pillar toward the tunnel member and forms a thick plate portion in collaboration with the front wall portion or the front wall portion and the lower wall portion.
