An electric powered vehicle including a traction motor is disclosed. The vehicle may further include a body including a cabin and a front body; a subframe mounted at a lower portion of the front body and supporting a suspension along with the front body; and a battery unit mounted a t a lower portion of the cabin and configured to supply electric power to the traction motor. The subframe may include a side rail extending in front-rear directions of the electric powered vehicle and is secured to a rail mount portion of the body at a rear end of the side rail. The battery unit may include a bracket projecting in a front direction of the front-rear directions and is secured to the rail mount portion of the body at the bracket.

A front vehicle-body structure of a vehicle includes: side frames of a suspension subframe; a cross member connecting front-end portions of the side frames in the vehicle width direction; a front beam member; and a connecting member connecting a front-end portion of each side frame to the front beam member. A high-rigidity portion having a higher rigidity than other portions of the side frame is at a connecting portion between the front-end portion of the side frame and the cross member. The front beam member has a side end portion extending on a vehicle-width-direction outer side relative to a connecting position with the connecting member. A protrusion portion protruding from the side end portion toward a vehicle rear side is to come into contact with the high-rigidity portion from the vehicle-width-direction outer side when a collision load from a vehicle front side is input to the side end portion.

In a vehicle subframe 1, a first side member has a first extending portion that extends while being deflected outward on one side in a width direction as approaching from a rear side to a front side, a second side member has a second extending portion that extends while being deflected outward on the other side in the width direction as approaching from the rear side to the front side, and a second cross member is further included which is opposed to the first cross member on the front side thereof and couples a portion of the first extending portion in which the degree of outward deflection on the one side in the width direction becomes large and a portion of the second extending portion in which the degree of outward deflection on the other side in the width direction becomes large to each other.

The disclosure provides a vehicle frame structure capable of achieving light weight and cost reduction while maintaining good structural rigidity. A vehicle frame structure includes a side frame and a support frame. The side frame is disposed at a side portion of a vehicle and extends in a vehicle front-rear direction. The support frame is disposed below the side frame to support a suspension member and includes a body portion, an arm portion extending upwards from the body portion, and a fixing portion disposed on an upper end of the arm portion. The fixing portion of the support frame and a lower end of the side frame are fixed to each other via a fastening member extending in a vehicle up-down direction. The fixing portion has a slit formed towards the outside in a vehicle width direction from a through hole into which the fastening member is inserted.

A battery rear undercover assembly for an eco-friendly vehicle enables the bottom of a vehicle to be flattened while covering a lower portion of the rear of a high-voltage battery in an eco-friendly vehicle. The battery rear undercover assembly includes a body having a front end that can be fastened to a lower portion of a rear end of a high-voltage battery and a battery rear undercover formed to extend from each of both side ends of the body upward and formed with a side cover that can be fastened to a vehicle body of a vehicle. The battery rear undercover assembly includes a reinforcement member formed in a longitudinal direction of the vehicle and fastened to an upper surface of the battery rear undercover.

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.

Disclosed are a subframe for a vehicle part having the high strength and high elongation by including the high iron content and an aluminum alloy composition with increased content of iron (Fe). The aluminum alloy composition includes an amount of about 0.15 to 0.25 wt % of iron (Fe), an amount of about 0.2 to 0.25 wt % of manganese (Mn), an amount of about 0.15 to 0.25 wt % of magnesium (Mg), an amount of about 7.5 to 9.0 wt % of silicon (Si), and an amount of about 0.5 wt % or less of inevitable impurities, and a balance of aluminum (Al), and all the wt % are based on the total weight of the aluminum alloy composition.

A siderail member for a subframe assembly of a vehicle, including: an elongate body, wherein the elongate body includes a hollow extruded structure including an inboard wall, an outboard wall, a top wall, a bottom wall, and one or more internal walls. Optionally, the bottom wall has a thickness that is greater than a thickness of the top wall. Optionally, the outboard wall has a thickness that is greater than a thickness of the inboard wall. Optionally, the one or more internal walls include a top internal wall and a bottom internal wall forming a plurality of horizontally-disposed cells within an interior of the elongate body. The bottom internal wall has a thickness that is greater than a thickness of the top internal wall. The hollow extruded structure is manufactured from an aluminum material. Optionally, the top wall of the hollow extruded structure defines a flexure recess.

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 vehicle body structure includes an engine cradle and an impact receiving structure. A forward end of the first side portion and a first lateral end of a front portion of the engine cradle are fixedly attached to one another. The first side portion has a rearward section and a forward section, the rearward section being horizontally oriented and the forward section extending upward and forward from the rearward section defining an acute angle therebetween, the acute angle being between 30 and 35 degrees. The impact receiving structure is installed to the first side portion of the engine cradle proximate an intersection between the first side portion and the front member. A lower surface of the impact receiving structure extends downward along the forward section of the first side portion further defining the acute angle of the forward section of the first side portion of the engine cradle.
