Supporting frame for a motor vehicle

摘要

A supporting frame for a motor vehicle has two parallel longitudinal members oriented in the longitudinal direction of the motor vehicle and form part of the body. Two longitudinal struts are oriented at least partially in the longitudinal direction and are fixed at first ends to a contact section of the longitudinal members. The longitudinal struts are connected at a second end opposite the first end to an impact plate that is arranged on at least one driving component of the motor vehicle to form a load path between the contact section of the longitudinal members and the at least one driving component.

1. A supporting frame for a motor vehicle, the motor vehicle having opposite first and second longitudinal ends spaced apart along a longitudinal direction of the motor vehicle, an electric driving unit in proximity to the first longitudinal end and a traction battery between the electric driving unit and the second longitudinal end, the supporting frame comprising:
first and second parallel longitudinal members oriented in the longitudinal direction of the motor vehicle and forming part of a body of the motor vehicle, each of the first and second longitudinal members having an end in proximity to the first longitudinal end of the motor vehicle; first and second longitudinal struts at least partially oriented in the longitudinal direction and each having a first end fixed to a contact section of the first or second longitudinal members at the end of the respective longitudinal member, each of the first and second longitudinal struts further having a second end opposite the first end; an impact plate opposed to and substantially adjacent the traction battery of the motor vehicle and between the traction battery and the electric driving unit, the impact plate being connected to the second ends of the longitudinal struts to form a load path between the respective contact sections of the longitudinal members and the traction battery, the impact plate having a plurality of side edges and opposite front and rear surfaces inward of the side edges, each of the front and rear surfaces defining an area substantially larger than an area defined by any of the side edges, the front and rear surfaces of the impact plate extending substantially perpendicular to the longitudinal direction so that impact energy in an event of a collision is transmitted via the longitudinal struts and the impact plate to the traction battery, thereby stiffening the motor vehicle at locations in proximity to the first end of the motor vehicle.
