A body includes a center tunnel that extends in a front-rear direction of a vehicle, a floor panel that extends from the center tunnel to both sides of the vehicle in a right-left direction, a floor cross member that is provided on an upper face of the floor panel and that extends in the right-left direction of the vehicle, straddling the center tunnel, and a reinforcing member joined to an upper face of the center tunnel and to a front face of the floor cross member.

Body of vehicle

An electrically driven vehicle includes at least one wheel driven by a motor, a vehicle body including a floor panel, a battery pack arranged on the lower side of the floor panel and configured to supply power to the motor, at least one wire harness extending in a front-rear direction of the electrically driven vehicle between the floor panel and the battery pack, and a harness cover extending in the front-rear direction of the electrically driven vehicle along the at least one wire harness and interposed between the at least one wire harness and the battery pack.

Electrically driven vehicle including wire harness cover

An electric vehicle structure may include a floor panel; a center tunnel disposed at a center of the floor panel in a vehicle width direction, extending along a vehicle front-rear direction, and projecting upward from the floor panel; a dash panel disposed at front ends of the floor panel and the center tunnel; and a front reinforcement attached to an inner surface of a peripheral wall of the center tunnel and extending rearward from the dash panel through the center tunnel.

Electric vehicle structure

An vehicle structure may include: a floor panel; a front crossmember disposed on the floor panel and below a front seat of a vehicle, and extending along a vehicle width direction; a rear crossmember disposed on the floor panel and rearward of the front crossmember, spaced apart from the front crossmember, and extending along the vehicle width direction; a center console disposed above the floor panel at a center of the floor panel in the vehicle width direction; and an air duct extending from the center console over the front crossmember and being open toward a position above the rear crossmember between the front seal and the floor panel.

Vehicle structure

Floor cross members provided above a floor panel are disposed so as to form a gap between each of the floor cross members and rockers. A floor cross extension that is set with a lower withstand strength than the floor cross members connects between each of the floor cross members and the corresponding rocker.

Vehicle body side section structure

Joining membersare provided that permit a rocker lowermoving toward a vehicle outer side at least along a direction of input of side collision load F when, at a time of a side collision of a vehicleside collision load F' that is greater than or equal to a set load that is set in advance is inputted to a rockerNamely, in a case in which the side collision load F&#x2032; that is greater than or equal to the set load is transmitted from a battery packto the rockerthe rocker lowermoves toward the vehicle outer side. Therefore, reaction force that the battery packreceives from the rockeris reduced, and collision load that is inputted to the battery packside is decreased.

Vehicle side portion structure

A vehicle side portion structure that includes: a pair of rockers arranged at each of two outer sides of a vehicle width direction of a floor panel of a vehicle, the rockers extending in a vehicle front-and-rear direction; and a plurality of cross-members that are arranged with length directions thereof in the vehicle width direction, both length direction end portions of each cross-member being fixed to the pair of rockers, and the cross-members being disposed to be spaced in the vehicle front-and-rear direction. A separation distance between neighboring cross-members in the vehicle front-and-rear direction is specified such that a bending reaction force of the rockers in response to an impact load applied during a side collision of the vehicle is equal to or greater than the impact load.

There is provided a vehicle lower section structure including a pair of rockers respectively provided at both vehicle width direction outer sides of a floor panel of a vehicle so as to extend in a vehicle front-rear direction, each of the rockers being configured including: an outer section that is positioned at the vehicle width direction outer side; an inner section that is integrally formed with the outer section, that is positioned at a vehicle width direction inner side, and that forms a closed cross-section section together with the outer section; and a first shock absorption section that is integrally formed with the outer section and the inner section, and that spans in the vehicle width direction between the outer section and the inner section within the closed cross-section section.

Vehicle lower section structure

A vehicle lower portion structure includes a pair of rocker panels and an electric power supply device. The rocker panel is configured to include an outer portion, an inner portion, and a first shock absorbing portion. The outer portion is positioned on an outer side in a vehicle width direction. The inner portion is formed integrally with the outer portion, is positioned inward of the outer portion in the vehicle width direction, and forms a closed sectional portion with the outer portion. The first shock absorbing portion extends in the vehicle width direction from the outer portion to the inner portion in the closed sectional portion and is disposed to overlap the electric power supply device in vehicle side view.

Vehicle lower portion structure

A crossing member disposed along a vehicle width direction between inflected portions of side members is capable of transmitting load from one of the side members to the other of the side members when the one side member deforms toward a vehicle width direction inward. Accordingly, when collision load is input due to an offset collision or the like, the collision load is transmitted from the one side member input with the collision load to the other side member through the crossing member, and the collision load is supported by the other side member.

A cross member is disposed inside a battery case. The cross member extends in the vehicle width direction at a location that overlaps with rockers as seen in the vehicle width direction. The cross member is more resistant to deformation by a load toward the battery case than a cover portion of the battery case. Therefore, when a load toward the battery case is applied, a transmission path for the load from the rocker at one vehicle width direction side to the rocker at the other vehicle width direction side may be formed by the cross member.
