Specific ribs in longitudinal crash beam
View Patent ↗A longitudinal crash beam in an electric vehicle for reducing the effects of a vehicle collision. The crash beam initiates a self-collapsing process in the event of a vehicle collision which may be triggered by the application of a longitudinal force to a set of impressions positioned along the outside surface of the crash beam. The crash beam may include a top side, a right side, a bottom side, a left side, and a plurality of diagonal sides. An upper cross rib, a lower cross rib, and a center rib may extend between the various sides of the crash beam. Benefits of the crash beam include increased rigidity of the vehicle, increased absorption of energy, and increased linearization of energy.
