  • Patent number: 8646790
    Abstract: A frame structure is adapted to absorb 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 at least one ramp connected to the pair of side frame under-members for directing rearward sliding movement of the rear sub-frame and attached structures downwardly beneath a battery assembly. A catching surface engages a steering gear to improve energy absorption during frontal impacts. A reinforcement bracket attached to the pair of side frame under-members defines a pocket for temporarily catching the rear sub-frame providing an energy absorption path before releasing the rear sub-frame to slide past. A tether is connected between the pair of side frame under-members and the rear sub-frame for holding the rear sub-frame against the ramp to increase energy absorption.

  • Patent number: 8646792
    Abstract: A vehicle frame structure is adapted to absorb energy from frontal impacts. The frame structure 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 a catching surface connected to the pair of side frame under-members for engaging the rear sub-frame and attached structures. A steering gear is attached to the rear sub-frame. The catching surface interacts with the steering gear to promote additional crushing energy absorption during sliding movement of the rear sub-frame relative to the catching surface during the frontal impact. The catching surface can be formed on ramps attached to the pair of side frame under-members. A tether can prolong crushing contact of the rear sub-frame with respect to the catching surface.
