Structure for managing loads during an impact event
A system for managing wheel kinematics during a small overlap collision event includes a deflector apparatus. The deflector is configured to direct a wheel away from an occupant compartment of a vehicle. The deflector includes a first section arranged at an inside wall of a wheel well facing a wheel, near the base of a hinge-pillar. The first section includes a hollow structure configured to absorb energy from the collision event by plastically deforming. The deflector also includes a second section arranged at an angle to the wheel and configured to deflect the wheel laterally outwards from the vehicle away from an occupant compartment during the small overlap collision event. The deflector may be formed of extruded aluminum. The system may include an absorber arranged behind the first section and configured to further absorb energy from the collision event by plastically deforming.
1. An apparatus comprising:
a crossmember having an end that extends outboard through a frame member of a vehicle; and
a structure comprising a rear portion spaced away from the end of the crossmember and further comprising a sidewall oriented longitudinally, wherein:
the structure is arranged outboard of the frame member and forward of the end of the crossmember such that the sidewall faces an outbound side of the frame member and such that a forward end of the sidewall is spaced closer to the outbound side of the frame member than the rear portion; and
the structure is configured to deform during an impact event such that the rear portion engages the end of the crossmember to apply a force on the end of the crossmember.
2. The apparatus of claim 1 , wherein the force comprises a lateral force, and wherein the rear portion comprises a rear curved corner configured to deform towards the end of the crossmember during the impact event to apply the lateral force on the end of the crossmember.
3. The apparatus of claim 2 , wherein the rear curved corner is spaced away from the frame member.
4. The apparatus of claim 1 , wherein the rear portion comprises a rear curved corner configured to deform towards and engage a forward edge of the end of the crossmember during the impact event.
5. The apparatus of claim 1 , wherein the impact event comprises a small overlap collision.
6. The apparatus of claim 1 , wherein the structure comprises an internal spine and a plurality of ribs.
7. The apparatus of claim 6 , wherein the internal spine extends between a front sidewall and a side sidewall of the structure.
8. The apparatus of claim 6 , wherein the structure is configured to deform such that the internal spine aligns with the end of the crossmember to impart a lateral force on the crossmember.
9. The apparatus of claim 1 , wherein the end of the crossmember comprises a forward edge and a rear edge.
10. The apparatus of claim 1 , wherein the end of the crossmember is angled such that a front length of the crossmember is shorter than a rear length.
11. The apparatus of claim 1 , wherein the structure comprises a wedge shape comprising a width the decreases towards the rear portion.
12. The apparatus of claim 1 , wherein the crossmember is rigidly affixed to the frame member.
13. The apparatus of claim 1 , wherein the crossmember extends through an opening in the frame member.
14. A frame system of a vehicle, comprising:
a crossmember comprising:
a first end that extends outboard through a first frame member of the vehicle; and
a second end that extends outboard through a second frame member of the vehicle; and
a structure comprising a rear portion spaced away from the first end of the crossmember and further comprising a sidewall oriented longitudinally, wherein:
the structure is arranged outboard of the first frame member and forward of the first end of the crossmember such that the sidewall faces an outbound side of the first frame member and such that a forward end of the sidewall is spaced closer to the outbound side of the first frame member than the rear portion; and
the structure is configured to deform during an impact event such that the rear portion engages the first end of the crossmember to apply a force on the first end of the crossmember.
15. The frame system of claim 14 , wherein the structure comprises a first structure, the frame system further comprising:
a second structure arranged outboard of the second frame member and forward of the second end of the crossmember, wherein:
the second structure is configured to deform during an impact event and apply a force on the second end of the crossmember.
16. The frame system of claim 14 , wherein the force comprises a lateral force, and wherein the rear portion comprises a rear curved corner configured to deform towards the first end of the crossmember during the impact event to apply the lateral force on the first end.
17. A vehicle comprising:
a first frame member arranged on a first side of the vehicle;
a second frame member arranged on a second side of the vehicle;
a bumper system affixed to the first frame member and the second frame member, wherein the bumper system is configured to receive a small overlap impact;
a crossmember laterally spanning the first frame member and the second frame member, wherein an end of the crossmember extends outboard through the first frame member; and
a structure having a rear portion spaced away from the end of the crossmember, wherein the structure is arranged outboard of the first frame member and forward of the end of the crossmember, wherein:
the structure is configured to deform during the small overlap impact such that the rear portion engages the end of the crossmember to apply a force on the end of the crossmember.
18. The vehicle of claim 17 , wherein the structure comprises a first structure and the end of the crossmember comprises a first end and wherein a second end of the crossmember extends outboard through the second frame member, the vehicle further comprising:
a second structure arranged outboard of the second frame member and forward of the second end of the crossmember, wherein:
the second structure is configured to deform during the small overlap impact and apply a force on the second end of the crossmember.
