Vehicle frame structure
A vehicle includes a body having a first rail and an upper rail spaced from the first rail. The upper rail has a base portion and a top prong and a bottom prong each extending from the base portion. The vehicle includes a bumper connected to the first rail and to the top prong, and a subframe connected to the bottom prong.
1. A vehicle, comprising:
a body having a first rail and an upper rail spaced from the first rail;
the upper rail having a base portion and a top prong and a bottom prong each extending from the base portion;
a bumper connected to the first rail and to the top prong; and
a subframe connected to the bottom prong;
the top prong having a bending point designed to bend upward in response to a front impact.
2. The vehicle of claim 1 , wherein the body includes a hinge pillar and the first rail and the base portion of the upper rail extend from the hinge pillar.
3. The vehicle of claim 2 , wherein the first rail, the top prong, and the bottom prong each have distal ends spaced from the hinge pillar, and wherein the bumper is connected to the distal ends of the first rail and the top prong, and wherein the subframe is connected to the distal end of the bottom prong.
4. The vehicle of claim 1 , wherein the subframe extends in a vehicle fore-and-aft direction from the body to the bottom prong, and wherein the subframe includes a bending point between the body and the bottom prong designed to bend downward in response to a vehicle frontal impact.
5. The vehicle of claim 1 , further comprising a crush can disposed between the bumper and a distal end of the first rail.
6. The vehicle of claim 1 , further comprising a crush can disposed between the bumper and a distal end of the top prong.
7. The vehicle of claim 1 , further comprising a first crush can between the first rail and the bumper, and a second crush can between the top prong and the bumper.
8. The vehicle of claim 7 , further comprising a plate connected to the first rail and to the top prong, the first crush can and the second crush can being connected to the plate.
9. The vehicle of claim 8 , further comprising a third crush can connected to the plate and to the bumper and disposed between the first crush can and the second crush can.
10. A vehicle body, comprising:
a bulkhead;
a hinge pillar;
a shock tower having an outboard side and an inboard side;
a first rail extending in a vehicle-forward direction from the bulkhead on the inboard side of the shock tower;
an upper rail on the outboard side of the shock tower, the upper rail having a base portion and a top prong and a bottom prong each extending from the base portion in the vehicle-forward direction;
a plate connected to the first rail and the top prong; and
a first crush can and a second crush can being connected to the plate;
the top prong having a bending point designed to bend upward in response to a front impact.
11. The vehicle body of claim 10 , wherein the base portion of the upper rail extends from the hinge pillar.
12. The vehicle body of claim 10 , wherein the top prong has an end spaced away from the bulkhead, and the end of the top prong and a distal end of the first rail are spaced a substantially equal distance from the bulkhead.
13. The vehicle body of claim 10 , further comprising a crush can disposed on a distal end of the first rail.
14. The vehicle body of claim 10 , further comprising a crush can disposed on a distal end of the top prong.
15. The vehicle body of claim 10 , further comprising a first crush can on the first rail, and a second crush can on the top prong.
16. A vehicle, comprising:
a body having a first rail and an upper rail spaced from the first rail;
the upper rail having a base portion and a top prong and a bottom prong each extending from the base portion;
a bumper connected to the first rail and to the top prong; and
a subframe connected to the bottom prong and connected to the body, the subframe extending from the bottom prong to the body.
17. The vehicle of claim 16 , wherein the subframe extends in a vehicle fore-and-aft direction from the body to the bottom prong, and wherein the subframe includes a bending point between the body and the bottom prong designed to bend downward in response to a vehicle frontal impact.
18. The vehicle of claim 16 , wherein the subframe extends from the bottom prong to the body below an engine compartment.
19. The vehicle of claim 16 , wherein the body includes a hinge pillar and the first rail and the base portion of the upper rail extend from the hinge pillar;
the first rail, the top prong, and the bottom prong each have distal ends spaced from the hinge pillar;
the bumper is connected to the distal ends of the first rail and the top prong; and
the subframe is connected to the distal end of the bottom prong and to the hinge pillar.
