The energy-absorbing impact assembly includes a ring assembly positioned on the rear side of the elongated center beam. The ring assembly includes a ring body and a plurality of struts that extend from the ring body. The bumper assembly, the tubular support, the crash box, or the ring assembly are configured to deform upon impact.

A vehicle includes a battery system arranged in a central region. The battery system includes corners corresponding to corners of an end of the vehicle, and respective chassis components are arranged at each corner. Respective shear brackets are affixed to the vehicle frame to a respective chassis component. The shear brackets are configured to absorb energy from the chassis components during deceleration events. The chassis components may include a knuckle configured to engage with the frame at an interface, to which the shear bracket may be added. Each shear bracket is formed from metal, such as sheet metal, and includes mounting features such as holes or studs to affix to the frame. The shear brackets are configured to limit intrusion of the chassis components into the battery system by absorbing energy. A bolt or fastener affixing a chassis component to the frame is strengthened by the shear bracket.

A powertrain assembly including a powertrain unit with a drive shaft, at least a first mount and at least a first coupling arm, arranged to direct the drive shaft substantially perpendicular to a driving direction of the vehicle. The first mount is arranged substantially perpendicular to the drive shaft. The first coupling arm is arranged between a first end side of the powertrain unit and the first mount and is connected to the powertrain unit by at least a first fixing element to hold the powertrain unit in an initial position. The first coupling arm is configured to clash into the first mount in case of a vehicle collision. The first fixing element is configured to be sheared off from the first coupling arm to at least partially disconnect the powertrain unit from the first coupling arms after the clash of the first coupling arm into the first mount.

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.

Embodiments of the present disclosure relate to a vehicle body reinforcement structure of an electric vehicle includes a front side member provided on both sides of the vehicle body along the vehicle body length direction, a cooling module mounted on the front side member, a frunk bar provided at the rear of the cooling module and an extension that mounts the frunk bar to the front side member with the center of the frunk bar being spaced apart from the center of the height direction of the cooling module.

A high voltage battery case assembly for a vehicle includes a battery case having a plurality of walls at least partially defining a cavity configured to receive one or more high voltage battery modules, a sacrificial pocket formed on an exterior of the battery case and including a thin-walled section, and an attachment bracket configured to couple between the sacrificial pocket and a body of the vehicle. The thin-walled section is configured to intentionally break away from the sacrificial pocket when the attachment bracket receives an impact load of a predetermined energy level to thereby facilitate protecting the high voltage battery case assembly from the impact load.

A battery enclosure for a vehicle chassis having a base member with raised surface features on the upper surface outlining individual cells, each cell configured to receive at least one battery; a cover member having a plurality of depending surface features on the lower surface which are aligned with the surface features of the base member. The cover member includes a channel formed in the upper surface thereof, aligned with and extending along a length of the depending surface feature disposed on the bottom surface. A lattice support structure is also included which has a plurality of support members extending axially and transversely, wherein the lattice support structure is configured to be at least partially disposed within the channel of the cover member and mounted to the vehicle chassis. The lattice support member providing increased rigidity and a load distribution path for externally applied forces (e.g. crash events) to prevent or inhibit enclosure breakage or puncture.

A bodywork support structure for a vehicle includes two side sills that are spaced apart in a transverse direction where the two side sills have a reinforcing element that is disposed in a hollow space. A floor is disposed between the two side sills and connected to the two side sills and an energy store for storing electrical energy and/or a fuel for powering the vehicle is disposed under the floor. The reinforcing element is formed as a corner reinforcement disposed in a corner area where the corner reinforcement has a first connection area that is attached to an external wall, a second connection area that is attached to a lower flange, and a wall area that connects the first and second connection areas with each other across the corner. An open space is formed between the corner reinforcement and an internal wall in the transverse direction of the vehicle.
