A vehicle body combination structure includes a center floor panel extending from a lower portion of a vehicle body along a longitudinal direction of the vehicle body, and a rear floor panel disposed at a rear of the vehicle body and connected to the center floor panel, wherein one end surface of the center floor panel and one end surface of the rear floor panel are vertically overlapped to form an overlap region, and wherein the rear floor panel and the center floor panel form a wheel base of the vehicle body.

A floor assembly for a motor vehicle has a front chassis module, in particular a front axle support, and a rear chassis module, in particular a rear axle support, as well as a housing of a stored electrical energy source, which is situated between the chassis modules as seen in the longitudinal direction of the floor assembly. The floor assembly includes at least one terminating component via which the housing of the stored electrical energy source can be fixed to a body part of the motor vehicle. The at least one terminating component is designed as a constituent part of at least one of the chassis modules. A motor vehicle includes such a floor assembly.

An embodiment component integration type rear lower includes a body frame having an end portion of a first side and an end portion of a second side and having a predetermined length, a front-rear connection member connecting a side sill at the end portion of the first side and connecting a rear side member at the end portion of the second side, a bush mounting member coupling a bush to the end portion of the first side, and a coupled torsion beam axle (CTBA) mounting member coupled to at least one of a CTBA, a chassis spring, or a shock absorber, the at least one of the CTBA, the chassis spring, or the shock absorber being engaged with the end portion of the second side.

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).

The present disclosure relates to a connecting structure between a quarter portion and a rear floor of a vehicle and, more specifically, to a connecting structure between a quarter and a rear floor, which can strengthen torsional rigidity of a vehicle body and secure durability of an opening of a tailgate.

A vehicle body rear portion includes a floor tunnel, a unit protection cover, and a rear floor panel. The floor tunnel is arranged at a middle in a vehicle width direction of a front floor panel. The unit protection cover covers an upper portion of a protection target unit which is arranged at a rearward position of the floor tunnel. The rear floor panel is arranged at a rearward position of the protection target unit. The unit protection cover and the rear floor panel include a reinforcement structure portion that extends in a vehicle body rearward direction from a tunnel ridge line at right and left upper portions of the floor tunnel.

A 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 and extending in a front-rear direction, a cross member extending and intersecting the center frame in a plan view in the occupant space, and a connecting member extending upward from the cross member, having an upper portion fixed to the center frame, and connecting the center frame to the cross member.

A vehicle body structure that includes a rear floor side member that extends along a vehicle front-rear direction at a vehicle width direction end portion of a vehicle rear section and that is divided into front and rear portions in the vehicle front-rear direction. The rear floor side member includes a joint section that is provided between a vehicle width direction inner side of a rocker rear, which is provided along the vehicle front-rear direction at a vehicle front-rear direction rear side of a rocker extending along the vehicle front-rear direction at a vehicle side section, and a vehicle front-rear direction front end of an attachment portion of a rear suspension member in vehicle side view, and that joins together a rear floor side member front portion and a rear floor side member rear portion.

There is provided a vehicle body structure, including: a die-cast rear floor side member; and a rocker rear inner; a joint section including: an upright wall configuring an inner side, in the vehicle width direction, of the rocker rear inner and extending along the vehicle vertical direction and the vehicle front-rear direction, and an outer joint section that is formed at the vehicle front-rear direction front end portion of the rear floor side member, that has an open cross-section profile, when sectioned along the vehicle vertical direction and the vehicle width direction, that is open toward an outer side in the vehicle width direction, that covers the rocker rear inner from the vehicle width direction inner side and that is joined to the rocker rear inner in a state in which a gap is provided between the outer joint section and the upright wall.

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.
