Hollow torque rod for a closure panel
View Patent ↗A compartment includes a plurality of side walls and a floor configured to define a storage area. The compartment also includes a panel operatively connected to the floor or to at least one of the plurality of side walls. The panel is configured to selectively expand and restrict access to the storage area. The compartment additionally include a torque rod having a wall thickness, a hollow interior, a first end fixed relative to the storage area and a second end fixed relative to the panel. The torque rod is configured to store energy by being twisted when the panel is pivoted in a first direction relative to the storage area and release the stored energy when the panel is pivoted in a second direction that is opposite to the first direction to thereby assist operation of the panel. A vehicle employing such an enclosure is also provided.

wherein the torque rod is configured to store energy by being twisted when the panel is pivoted in a first direction relative to the storage area and release the stored energy when the panel is pivoted in a second direction that is opposite to the first direction to thereby assist operation of the panel; and
wherein at least one of the first and second ends of the torque rod includes a compressed, substantially flat portion.
2. The compartment of claim 1 , wherein the compartment is a bed of a pick-up truck and the panel is a tailgate configured to selectively open and close access to the bed.
3. The compartment of claim 1 , wherein the compartment is a trunk area of a vehicle and the panel is a trunk lid configured to selectively open and close access to the trunk area.
4. The compartment of claim 1 , wherein the substantially flat section is fixed relative to one of the storage area and the panel.
5. The compartment of claim 1 , wherein at least one of the first and second ends of the torque rod includes a solid segment, wherein the solid segment is at least one of pressed and welded into the hollow interior, and wherein the solid segment includes a keyed section fixed relative to the storage area or to the panel, respectively.
6. The compartment of claim 1 , wherein the second end of the torque rod includes a formed loop which is secured to the panel.
7. The compartment of claim 1 , further comprising a bracket fixed to at least one of the plurality of side walls and the floor, wherein the first end of the torque rod is inserted into and is fixedly engaged by the bracket.
8. The compartment of claim 1 , wherein the first end of the torque rod includes a flange which is fastened to at least one of the plurality of side walls and the floor.
9. The compartment of claim 1 , further comprising a hinge mechanism configured to pivotably connect the panel to one of the plurality of side walls and the floor.
10. The compartment of claim 9 , wherein the second end of the torque rod is fixed to the hinge mechanism.
11. A vehicle comprising:
a passenger compartment; and
a storage compartment having:
a plurality of side walls and a floor configured to define a storage area;
a panel operatively connected to at least one of the floor and at least one of the plurality of side walls, and configured to selectively expand and restrict access to the storage area; and
a torque rod having a wall thickness, a hollow interior, a first end fixed relative to the storage area and a second end fixed relative to the panel;
wherein the torque rod is configured to store energy by being twisted when the panel is pivoted in a first direction relative to the storage area and release the stored energy when the panel is pivoted in a second direction that is opposite to the first direction to thereby assist operation of the panel; and
wherein at least one of the first and second ends of the torque rod includes a compressed, substantially flat portion.
12. The vehicle of claim 11 , wherein the storage compartment is a bed of a pick-up truck and the panel is a tailgate configured to selectively open and close access to the bed.
13. The vehicle of claim 11 , wherein the storage compartment is a trunk area of a vehicle and the panel is a trunk lid configured to selectively open and close access to the trunk area.
14. The vehicle of claim 11 , wherein the substantially flat section is fixed relative to one of the storage area and the panel.
15. The vehicle of claim 11 , wherein at least one of the first and second ends of the torque rod includes a solid segment, wherein the solid segment is at least one of pressed and welded into the hollow interior, and wherein the solid segment includes a keyed section fixed relative to the storage area or to the panel, respectively.
16. The vehicle of claim 11 , wherein the second end of the torque rod includes a formed loop which is secured to the panel.
17. The vehicle of claim 11 , further comprising a bracket fixed to at least one of the plurality of side walls and the floor, wherein the first end of the torque rod is inserted into and is fixedly engaged by the bracket.
18. The vehicle of claim 11 , wherein the first end of the torque rod includes a flange, which is fastened to at least one of the plurality of side walls and the floor.
19. The vehicle of claim 11 , wherein the storage compartment additionally includes a hinge mechanism configured to pivotably connect the panel to one of the plurality of side walls and the floor.
20. The vehicle of claim 19 , wherein the second end of the torque rod is fixed to the hinge mechanism.
