In an embodiment a towing pipe connection structure includes a vehicle body rear member including an aluminum material, a towing pipe at least partially including an aluminum material and a connection bracket including a bumper back beam plate in contact with a back panel of a vehicle body and including an insertion hole into which the towing pipe is inserted, an engage plate having an engage hole to which the towing pipe is connected and a connection plate connecting the bumper back beam plate and the engage plate, wherein the connection bracket is connected to a rear member of the vehicle body, and wherein the connection bracket includes an aluminum material.

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 support extrusion for a subframe structure of a vehicle and methods of fabricating the same. In one example, a support extrusion can comprise a multicell structure that facilitates coupling the support extrusion with a rear crossmember of the subframe structure. The multicell structure can comprise a front cell column and a rear cell column that intervenes between the front cell column and the rear crossmember in a longitudinal direction of the subframe structure. The front cell column can comprise a trigger that facilitates plastically deforming the front cell column downward in a vertical direction of the subframe structure when subjected to impact forces of a frontal crash.

A vehicle body lateral section structure includes: a side panel outer (2) that is made of an aluminum alloy; a reinforcing member (4) that is made of steel and overlaps inside the side panel outer (2); an inner panel (3) that is made of steel and overlaps inside the reinforcing member (4); a plurality of mechanical coupling portions (5) that are provided at an interval (P1) of 40 mm or more and 80 mm or less in a longitudinal direction of the opening flange; and resistance welded portions (6) that are provided between the plurality of mechanical coupling portions (5) in the longitudinal direction to join the reinforcing member (4) and the inner panel (3) to each other in a state where the side panel outer (2), the reinforcing member (4), and the inner panel (3) overlap each other in three layers.

A subframe assembly for a vehicle utilizing straight, parallel extruded longitudinal siderail members. This subframe assembly provides front-end (or rear-end) crash energy absorbance by plastically deforming, crumpling, and bending down to avoid the stackup and occupant cabin intrusion of components, such as the attached engine/motor, engine/motor mounts, steering components, and suspension components. The laterally disposed longitudinal siderail members each provide a straight, substantially uninterrupted lower load path to transfer crash energy from the lower load path crash management system beam and crashboxes or the like to a rear upper load path body in white bracket, and ultimately to the battery frame in the event of a crash, with the siderail members and crashboxes optionally being longitudinally coaxially aligned.

A body for a vehicle includes a base part extending in a longitudinal direction of the vehicle and including a flange portion being open outward of the vehicle, a tubular part accommodated on and coupled to the flange portion of the base part and shaped in a pipe with a closed section, and an external garnish coupled to the base part or the tubular part to cover an external portion of the tubular part.

A vehicle structure comprising a portion extending in a longitudinal direction, wherein the portion comprises a first member extending in the longitudinal direction and a second member extending in the longitudinal direction. The first member is configured to face an inside of a vehicle, and the second member is configured to face an outside of the vehicle. The first and second members are attached to one another to form a closed space between them. The portion comprises a wave-shaped first tubular reinforcement member located in the closed space.
