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.

A chassis platform module for an electric vehicle may include: a frame part having a battery mounted thereon; a first support part extended from one side of the frame part in a longitudinal direction, and having a front wheel chassis module mounted thereon; and a second support part extended from the other side of the frame part in the longitudinal direction, and having a rear wheel chassis module mounted thereon.

A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.

A front vehicle-body structure is provided that allows for lower deceleration for occupants by facilitating breakage of frame members in the event of an oblique collision. Embodiments include a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A first frame connects an upper portion of the suspension housing and an upper portion on a vehicle-width-direction inner side of a dash panel, a second frame connects the upper portion of the suspension housing and an upper portion of a hinge pillar, and a third frame connects a lower portion of the suspension housing and a lower portion on the vehicle-width-direction inner side of the dash panel. In the event of an oblique collision, the first frame and the second frame break inward in vehicle plan view, and the third frame breaks in a Z-shape in vehicle plan view.

A vehicle front body structure includes a front side frame extending forward from a dashboard separating a cabin and an engine compartment, an apron reinforcement extending in a front-rear direction, a suspension housing, a braking force booster between this suspension housing and the dashboard, and a coupling member coupled to the front side frame and the apron reinforcement. The coupling member is formed of a material with higher tensile strength than the suspension housing. The coupling member includes a body section fixed to a rear surface of the suspension housing, and a wall section. bent from a lower end of this body section and extending rearward.

Energy absorption at the time of load input is improved with high mass efficiency. A hollow member includes: a hollow metal member having a bending induction portion in a portion thereof in a longitudinal direction; and a resin material which is disposed in close contact with the metal member on both sides of the bending induction portion in the longitudinal direction, and is disposed in at least a part of a range of less than ⅚ of a cross-sectional height of the metal member from an end portion of the bending induction portion toward an outside in the longitudinal, in which an amount of the resin material per length in the longitudinal direction is larger on the outside of the bending induction portion than on an inside of the bending induction portion.

A vehicle includes a body. The vehicle includes a front bumper reinforcement that is attached to a front end of the body, and extends along a vehicle width direction. The vehicle includes a lower bumper reinforcement that is attached to the front end of the body, is located under the front bumper reinforcement, and extends along the vehicle width direction. The vehicle includes at least one specific member that is fixed to a partial section of the lower bumper reinforcement along an extending direction of the lower bumper reinforcement. Each of the at least one specific member includes a first portion that covers a front face of the lower bumper reinforcement, and a second portion that protrudes more upward than an upper face of the lower bumper reinforcement.

A support frame assembly configured to strengthen an upper frame portion of a frame of a vehicle, comprising a first frame member having a first end and a second end, and a second frame member having a first end and a second end, wherein both the first ends of the first and second frame members are configured to couple to a front half of the frame and the second ends of the first and second frame members are configured to couple to the front half of the frame to strengthen the upper frame portion, at least one of the first and second ends of each of the first and second frame members including at least one mechanically coupled joint configured for coupling each of the first and second frame members to the front half of the frame.

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 motor vehicle has a passenger compartment and two longitudinal members provided with respective rear portions arranged longitudinally in the area of the passenger compartment and with respective struts, which project forward relative to the passenger compartment; the motor vehicle further has a powertrain, which is supported by the cross member and/or by the struts, and a cross member with front connection points connected to the longitudinal members so as to be suspended, by means of respective breakable connection members, and with rear connection points connected to the aforesaid rear portions by means of connection devices having weakened areas designed so as to break when a given load threshold is exceeded, in order to completely uncouple the cross member from the longitudinal members.
