Abstract

A body-mounted tire blocker assembly can absorb and/or manage energy when a vehicle body assembly is subjected to an external force. This vehicle body assembly may include a vehicle body defining a passenger compartment. The vehicle body further includes a rocker panel defining a first panel end and a second panel end opposite the first panel end. The tire blocker assembly is coupled to the rocker panel and includes a first blocker body and a second blocker body coupled to the first blocker body. The first blocker body is farther from the first panel end than the second blocker body in order to guide a wheel away from the passenger compartment when an external force is applied to the vehicle body.

First claim

The invention claimed is:

1. A vehicle body assembly, comprising:
a vehicle body defining a passenger compartment, wherein the vehicle body includes a rocker panel, the rocker panel defines a first panel end and a second panel end opposite the first panel end; and
a tire blocker assembly coupled to the rocker panel, wherein the tire blocker assembly includes a first blocker body and a second blocker body coupled to the first blocker body, and the first blocker body is farther from the first panel end than the second blocker body in order to guide a wheel away from the passenger compartment when an external force is applied to the vehicle body;
wherein the first blocker body comprises a first material, the second blocker body comprises a second material, the first material has a first yield strength, the second material has a second yield strength, the second yield strength is less than the first yield strength to allow the second blocker body to absorb energy when the external force is applied to the vehicle body; and
wherein the rocker panel extends along a longitudinal direction, and the first blocker body includes a deflecting wall extending along a lateral direction, and the lateral direction is perpendicular to the longitudinal direction.

2. The vehicle body assembly of claim 1 , wherein the first blocker body has a first maximum thickness, the second block body has a second maximum thickness, and the first maximum thickness is greater than the second maximum thickness.

3. The vehicle body assembly of claim 2 , wherein the first panel end is spaced apart from the second panel end along the longitudinal direction, and the tire blocker assembly is closer to the first panel end than to the second panel end.

4. The vehicle body assembly of claim 3 , further comprising a rocker end cap directly coupled to the first panel end, and the tire blocker assembly is directly coupled to the rocker end cap.

5. The vehicle body assembly of claim 4 , wherein the first blocker body includes a first flange coupled to the deflecting wall, the first flange is closer to the rocker end cap than to the deflecting wall, and the vehicle body assembly further includes at least one fastener extending through the first flange and the rocker end cap.

6. The vehicle body assembly of claim 5 , wherein the first blocker body includes an upper coupling wall interconnecting the deflecting wall and the first flange.

7. The vehicle body assembly of claim 6 , wherein the second blocker body includes an energy-absorbing wall extending along the lateral direction.

8. The vehicle body assembly of claim 7 , wherein the first blocker body includes a first connecting wall directly interconnecting the first flange and the deflecting wall, the second blocker body includes a second connecting wall, the second connecting wall is closer to the rocker end cap than the energy-absorbing wall, and the second connecting wall is obliquely angled relative to the energy-absorbing wall.

9. The vehicle body assembly of claim 8 , wherein the second blocker body includes a second flange, the second connecting wall directly interconnecting the energy-absorbing wall and the second flange, the second connecting wall is parallel to the first connecting wall, and the deflecting wall is parallel to the energy-absorbing wall.

10. A vehicle, comprising:
a vehicle body defining a passenger compartment, wherein the vehicle body includes a rocker panel, and the rocker panel defines a first panel end and a second panel end opposite the first panel end;
a frame supporting the vehicle body, wherein the frame includes frame rail;
a mount directly coupled to the frame rail;
a wheel coupled to the frame; and
a tire blocker assembly coupled to the rocker panel, wherein the tire blocker assembly includes a first blocker body and a second blocker body coupled to the first blocker body, and the first blocker body is farther from the first panel end than the second blocker body in order to guide the wheel away from the passenger compartment when an external force is applied to the vehicle body; and
a shield directly coupled to the frame rail, wherein the shield is disposed between the wheel and the mount, and the shield partially surrounds the mount in order to prevent the wheel from moving toward the passenger compartment when an external force is applied to the vehicle body.

11. The vehicle of claim 10 , wherein the shield includes a first bar portion and a second bar portion directly connected to the first bar portion, and the first bar portion and the second bar portion are obliquely angled relative to each other.

12. The vehicle of claim 11 , wherein the rocker panel extends along a longitudinal direction, the first blocker body includes a deflecting wall extending along a lateral direction, the lateral direction is perpendicular to the longitudinal direction, and the deflecting wall is positioned relative to the shield such that the deflecting wall guides the wheel toward the shield when the external force is applied to the vehicle body.

13. The vehicle of claim 12 , wherein the first blocker body comprises a first material, the second blocker body comprises a second material, the first material has a first yield strength, the second material has a second yield strength, the second yield strength is less than the first yield strength to allow the second blocker body to absorb energy when the external force is applied to the vehicle body.

14. The vehicle of claim 13 , the rocker panel extends along the longitudinal direction, the first panel end is spaced from the second panel end along the longitudinal direction, the vehicle body further includes a rocker end cap directly coupled to the first panel end, and the tire blocker assembly is directly coupled to the rocker end cap, and the tire blocker assembly further includes a fastener extending through the first blocker body, the second blocker body, and the rocker end cap to directly couple the tire blocker assembly to the rocker end cap.

15. The vehicle of claim 14 , wherein the first blocker body has a first maximum thickness, the second block body has a second maximum thickness, and the first maximum thickness is greater than the second maximum thickness.
