Construction method to control front engine compartment deformation

A frame structure absorbs energy from frontal impacts and extends under a front portion of the body frame. The frame structure includes a rear sub-frame located below and in front of a pair of side frame under-members, and an inverter protection brace extending between the front sub-frame and the re...

More Information
Summary:A frame structure absorbs energy from frontal impacts and extends under a front portion of the body frame. The frame structure includes a rear sub-frame located below and in front of a pair of side frame under-members, and an inverter protection brace extending between the front sub-frame and the rear sub-frame. Loading from the inverter protection brace travels through the rear sub-frame to A-point bolt connections located on the pair of front frame side members. The rear sub-frame moves rearward and deforms at the A-point bolt connections. The load through the A-point bolt connections changes the deformation mode of the frame front side members between the A-point bolt connections and B-point bolt connections. At least one of the pair of side frame under-members buckles rearward of the B-point bolt connection located on the pair of side frame under-members for energy absorption during the frontal impact.
