A vehicle frame structure includes a front wall portion and a rear wall portion that are respectively provided in front and rear end portions of a vehicle, a side wall portion extending in the vehicle front-rear direction so as to separate the vehicle cabin from the exterior of the vehicle cabin, and a connecting portion that includes a first end portion and a second end portion, and has a closed section structure that is curved so as to protrude inward in the vehicle width and front-rear directions in a plan view. The first end portion is connected to an inner side of one of the front wall portion and the rear wall portion in the vehicle front-rear direction, and the second end portion is connected to an inner side of the side wall portion in the vehicle width direction.

A vehicle body lower structure may include: a hollow rocker arranged at a lower lateral part of a vehicle body and extending along a front-rear direction of the vehicle body; a power source arranged adjacent to the rocker; an energy absorbing member connected to the power source and arranged under the rocker; and a collar arranged between the rocker and the energy absorbing member. The rocker may be provided with a flange extending downward from a bottom plate of the rocker. A height of the collar above the energy absorbing member may be greater than a height of the flange.

A lower vehicle-body structure of a vehicle may include: a floor panel; a side sill; and a frame member that extends in the front-rear direction on the vehicle-width-direction inner side of the side sill and includes a front-rear extended portion that is in abutment against the side sill on the vehicle-width-direction inner side and extends in the vehicle front-rear direction along the side sill. The front-rear extended portion may include: a bottom face portion; an inner wall portion; and an inner-side flange that extends to the vehicle-width-direction inner side from a distal end portion of the inner wall portion and is joined to the floor panel. Deformation facilitating facilitators that facilitate deformation of the bottom face portion in the vehicle width direction when a collision load in the vehicle width direction is input may be formed in the bottom face portion.

The present disclosure provides a chassis collision structure of a new energy vehicle, comprising a front lower collision beam assembly, a front sub-frame assembly, a front battery pack bottom fender, a rear battery pack bottom fender, and a rear sub-frame assembly which are arranged sequentially along a direction from a head to a tail of a vehicle, wherein the front lower collision beam assembly is connected to a front end of the front sub-frame assembly; the front battery pack bottom fender is connected to a bottom of the front sub-frame assembly; the rear battery pack bottom fender is connected to a bottom of the rear sub-frame assembly; and connecting parts which are connected with a battery pack are arranged at one end of the front battery pack bottom fender and one end of the rear battery pack bottom fender, which are close to each other, respectively.

A floor assembly for an electrically operable motor vehicle includes a vehicle floor, which runs on top of an energy storage device for driving the vehicle, has at least one floor element, and to which a side sill is attached on each outer side. In order to ensure that the energy storage device below the vehicle floor is protected against excessive damage in the event of a crash, in particular a side-impact crash, a first, outer, deformation zone of the floor assembly is provided in the region of the side sills, with the energy storage device being arranged at a distance from the first, outer deformation zone in the transverse direction of the vehicle so as to form a second, inner, deformation zone. The first, outer, deformation zone is deformable under a lower load level than the second, inner, deformation zone.

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.

An emergency response barrier is shown and described, the barrier having a cab and engine for propelling the barrier; a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; wherein the frame is covered with a substantially planar skin that extends along the right and left sides of the frame, from a top of the frame down to a lower edge and covers a majority of the wheels on each side of the barrier; an impact attenuator coupling on the frame, having a vertical pin received in a bore disposed on an impact attenuator, and configured for rotation about the vertical axis of the pin; and a hydraulic cylinder connected between the frame and the impact attenuator, wherein retraction and extension of the hydraulic cylinder moves the impact attenuator through an arc of rotation about the vertical pin.

An energy dissipation system for a frame of a vehicle includes a frame rail including a crushable region and a non-crushable region. An energy dissipation device includes an energy transfer portion arranged partially in the crushable region and partially in the non-crushable region and configured to move in response to a vehicle impact on the frame rail. An energy dissipation portion is arranged within the non-crushable region, connected to the energy transfer portion. The energy dissipation device includes a first region connecting the energy dissipation portion to the non-crushable region, and a second region connecting the energy dissipation portion to the energy transfer portion. The first region of the energy dissipation portion is stiffer than the second region of the energy dissipation portion.
