Vehicle frames for battery powered electric vehicles are disclosed. An example apparatus disclosed herein includes a vehicle subframe including a first rail and a first rocker on a first side of the vehicle subframe, and a second rail and a second rocker on a second side of the vehicle subframe, the first side opposite the second side, a first diagonal member coupled between the first rail and the second side of the vehicle subframe, the first diagonal member to transfer a first longitudinal load from the first rail to the second side, and a second diagonal member coupled between the second rail and the first side of the vehicle subframe, the second diagonal member to transfer a second longitudinal load from the second rail to the first side.

A front lower body structure of a vehicle includes a front side rear lower member connected from a front side member disposed on one side of a fender apron to a side sill inner, a center floor side upper member disposed in a longitudinal direction of the vehicle and extending from an upper surface of a dash panel to a center floor panel, and a reinforcement bracket connecting the front side rear lower member with the center floor side upper member.

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 top surface of 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 at a point where the internal side member and the battery cross member intersect.

A sub-frame mounting combination structure of a vehicle body may include a fender apron side member mounted at the rear end portion of a front side member in the longitudinal direction of the vehicle body, a first side extension disposed in the transverse direction of the vehicle body and connected to the inside of the fender apron side member, a second side extension disposed in the transverse direction and connected to the outside of the fender apron side member, a tunnel member disposed in the transverse direction connecting the first side extensions at both sides at the center portion of the vehicle body to each other, and having the same phase as the first side extension, and a cap type bracket disposed to cover the fender apron side member at a portion where the fender apron side member and the first and second side extensions are connected.

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.

An underbody for a vehicle may arrange and couple a plurality of assemblies forming the underbody in a vertically laminating structure. The underbody includes a panel assembly configured to form a floor of a vehicle interior; an upper member assembly configured to be laminated on and coupled to an upper side of the panel assembly; and a lower member assembly configured to be laminated on and coupled to a lower side of the panel assembly and coupled to a side portion of the panel assembly and a side portion of the upper member assembly

A front vehicle body structure includes a front mounting bracket and a front side upper member that is connected to the front mounting bracket. The front side upper member includes an upper member upper surface that is inclined upward and rearward of the vehicle body. A front flange is formed downward from the upper member upper surface and is connected to the front mounting bracket.

An injury preventing structure located in a vehicle is provided and comprises a lower member and an upper member which distribute impact of a vehicle, and a panel which forms a bottom surface of the vehicle, in which the upper member and the lower member are in contact with the panel to form a dosed cross-section between each member and the panel, and a position at which the panel is in contact with a rear end of the upper member and a position at which the panel is in contact with a front end of the lower member at least partially overlap each other to form a collision transformation support shaft. Accordingly, it is possible to prevent injury of the legs of a first or frontrow occupant even with a reduced cross-section of the upper member. It is additionally possible to further reduce the first row space of the vehicle, thereby also securing the rear seat and cargo loading space.

A motor vehicle has a body with a front section, a floor structure which adjoins the front section, and a floor panel, on the two longitudinal sides of which a sill is in each case arranged. The sills run from an A pillar, adjoining the front section, of the body as far as a C pillar of the body. An inner longitudinal member is on each longitudinal side of the floor panel. A bulkhead is arranged between the front section and the floor structure. Each sill is constructed from an inner C profile and an outer C profile. The first and second profile flanges of the C profiles, arranged in an overlapping manner, are connected, in particular welded, to the inner longitudinal member.

A vehicle underbody structure includes a catalyst disposed in a front portion of an exhaust pipe; a cover member for covering the catalyst from above; and a heat insulator disposed inside a tunnel portion behind the catalyst and configured to cover the exhaust pipe from above. The heat insulator is disposed away from the tunnel portion by a predetermined gap in an up-down direction. A front portion of the heat insulator and a rear portion of the cover member are disposed in such a way as to overlap each other. A front end of the heat insulator is disposed on the upper side with respect to a rear end of the cover member.
