A vehicle-body structure both protects a battery and provides a routing member below a floor panel that improves underfloor aerodynamic performance. Embodiments of a vehicle-body structure may include: a routing member that extends in a vehicle front-rear direction on a vehicle-width-direction outer side of a battery frame below a floor panel; a cover member that extends from a lower side of a battery to a lower side of the routing member; battery-frame fixation portions that fix the battery frame to side sills; and cover-member fixation portions that fix a vehicle-width-direction end portion of the cover member to the side sills. The routing member and the battery-frame fixation portions may be positioned on a vehicle-width-direction inner side of the cover-member fixation portions.

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.

A vehicle-body structure may include a floor panel, a center frame disposed to be higher than and away from the floor panel, and an air-conditioning device. The air-conditioning device may include an air distribution portion that is positioned higher than a front portion of the center frame and distributes generated air-conditioned air to each portion of an occupant space, and under-feet ducts that guide air-conditioned air to a lower side. The under-feet ducts each may extend downward from the upper side of the center frame through a vehicle-width-direction outer side of the center frame.

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 member joint device for a vehicle includes a pair of cross members arranged laterally; two pairs of rail members, each pair being arranged longitudinally; and a member joint crosswise-connecting the cross members and the rail members and for running and carrying wires and pipes, enhancing rigidity therebetween, and convenience to easily install electric component wires and chassis component pipes in desired route directions.

A structure for assembling a vehicle having an axis of elongation, a frame rail and a cross member extending from the frame rail comprises a conduit extending along the axis of elongation of the vehicle. A conveyor is disposed in the conduit. At least one coupling attaches the conduit with at least one of the frame rail and the cross member.

This disclosure details integrated thermal management systems for thermally managing electrified vehicle components. Exemplary integrated thermal management systems may include a thermal module assembly that may be integrated into a front end structure of a flexible modular platform of the electrified vehicle. The integrated thermal management systems may be controlled in a plurality of distinct thermal control modes for thermal managing various subcomponents and for addressing various vehicle auxiliary loads (e.g., passenger cabin heating loads, passenger cabin cooling loads, etc.).
