Patent granted for an electric vehicle with impact management system
A recently granted patent (Publication Number: US11753078B2) describes an electric vehicle with an impact management system designed to maintain the structural integrity of the vehicle's frame in the event of an impact. The vehicle includes a frame structure with a pair of rails that extend longitudinally. It is powered by at least one electric motor.
The impact management system consists of a crash cage, which includes a pair of upright inner posts directly affixed to the pair of rails. These inner posts are arranged perpendicular to the rails and are partially offset inward in a lateral direction. Additionally, the crash cage includes a first lower beam that is parallel to one of the rails and offset inward in the lateral direction. A second lower beam is parallel to the other rail and also offset inward. The crash cage further comprises a pair of upright outer posts located outwardly of the inner posts in the lateral direction.
The crash cage is designed to deform in response to impact forces, ensuring the structural integrity of the rails. It includes upper and lower beams, crossbars, and struts that interconnect the various components. The crash cage also features a crash wall that connects the upper beams and is positioned adjacent to the forward-most point of the vehicle. The crash cage is configured to withstand forces applied in directions that are not parallel to the longitudinal direction.
Overall, this patent describes an electric vehicle with an impact management system that effectively protects the structural integrity of the vehicle's frame during impacts. The crash cage, consisting of inner and outer posts, lower and upper beams, crossbars, and struts, is designed to deform and absorb impact forces, ensuring the safety of the vehicle and its occupants.
