A vehicle body rear connection structure includes an extension rear transverse that connects a pillar member disposed in a vertical direction of a vehicle body to a transverse member disposed in a width direction of the vehicle body at a rear of the vehicle body, and of which a seat belt mounting portion is formed, and a reinforcement transverse extension which is mounted on a side of the extension rear transverse, and a lower portion of which is connected to a floor panel.

This rear vehicle body structure includes a first floor cross member disposed on a vehicle front side with respect to a battery and connected to a rear side frame extending in a vehicle front-rear direction on an outer side in a vehicle width direction, and a second floor cross member disposed on a vehicle rear side with respect to the battery, in which the first floor cross member includes a widened part widened in the vehicle front-rear direction at an end portion and extending to a position at which it overlaps the battery, and a boundary part between the widened part and the rear side frame is disposed at a position at which it overlaps the battery in a side view.

A rear portion of a vehicle body includes a front floor panel, a rear floor panel, a pair of left and right side sills, and a front cross plate. The rear floor panel has a higher upper surface height than the front floor panel. The front cross plate connects a rear portion of the front floor panel and a front wall of the rear floor panel, and an outer end portion in a vehicle width direction is coupled to the left and right side sills. The front wall of the rear floor panel has a plurality of bent corner portions having a side view shape bent in a substantially L shape. At least one of the bent corner portions constitutes a closed cross section extending along the vehicle width direction together with the front cross plate in a vertical height range of the left and right side sills.

Systems and methods are presented herein for a vehicle frame comprising a first rail member and a second rail member. Each of the first rail member and the second rail member comprise a front rail portion, wherein the front rail portion is configured to provide resistance to deformation to protect a battery pack assembly positioned between the first rail member and the second rail member. Additionally, each of the first rail member and the second rail member comprise a rail portion, wherein the rail portion is structured to mechanically deform when subjected to a threshold impact force.

A structural reinforcement utilized to reinforce a structural joint of a vehicle, and method of enforcing a structural joint of a vehicle. The structural reinforcement having a clamshell structure comprising two complimentary halves. The structural reinforcement further comprising an activatable composition.

A rear structure of a vehicle includes: a rear floor, and a pair of diagonal members coupled to a bottom surface of the rear floor, extending obliquely from both sides of the rear floor to a rear side of the rear floor, and symmetrical with respect to a longitudinal centerline of the rear floor. The rear structure further includes a pair of side extensions coupled to the bottom surface of the rear floor at the both sides of the rear floor, respectively, and extending in a longitudinal direction of the rear floor. The rear structure includes a cross member disposed between the pair of side extensions at a rear bottom surface of the rear floor, and the cross member has both ends each spaced apart from a corresponding side extension.

A rear vehicle body structure includes a wheel housing including a wheel housing inner panel, a shock absorber mounting bracket mounted on the outside of the wheel housing inner panel, and a wheel housing reinforcement mounted inside the wheel housing inner panel and connected to the shock absorber mounting bracket.

Rear structure for an electric vehicle having a rear rail which includes a rear portion, a front portion and a transition zone, such that in the event of a rear crash the rear portion and the transition zone are both able to deform to maximize the amount of energy absorption.

A hood lifting mechanism for a vehicle having a frunk, including: at least one lifting means configured to lift a hood, and a deformable material configured to be attached to an inner surface of the hood, wherein the deformable material is configured to switch from a first position (P1) in which the deformable material is either flat or forms a dome being directed towards the inner surface of the hood into a second position (P2) in which the deformable material forms a dome being directed towards the frunk when the at least one lifting means is activated. Further, the present disclosure relates to a vehicle including such lifting mechanism and to a method for moving a hood of a vehicle.

A component of a motor vehicle, which is reinforced in at least one region subject to tensile loading by at least one stiffening tape having fibers embedded in plastic. This should make it possible to achieve local and weight-optimized stiffening.
