Rocker insert with corrugated structure
A vehicle rocker assembly may include a sill inner comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly may also include a sill outer comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly also includes a rocker insert disposed within the elongated hollow interior, the rocker insert comprising: an upper wall, a lower wall, and a side wall extending between the upper wall and the lower wall. At least one of the upper wall or the lower wall comprises a corrugated portion that has a ridge oriented to extend in a lateral vehicle direction.
1. A vehicle rocker assembly comprising:
a sill inner;
a sill outer coupled with the sill inner to define an elongated hollow interior between the sill inner and the sill outer; and
a rocker insert disposed within the elongated hollow interior, the rocker insert comprising a corrugated portion that has a ridge oriented to extend in a lateral vehicle direction between the sill inner and the sill outer,
wherein the rocker insert comprises a tubular member extending longitudinally along the elongated hollow interior and at least partially defined by an upper wall, a lower wall, and opposing side walls extending between the upper wall and the lower wall, and
wherein at least one of the upper wall or the lower wall include the corrugated portion of the rocker insert with the ridge extending at least partially between the opposing side walls of the rocker insert.
2. The vehicle rocker assembly of claim 1 , wherein the corrugated portion comprises at least a portion of metal sheet.
3. The vehicle rocker assembly of claim 1 , wherein a cross-sectional shape of the corrugated portion along a longitudinal vehicle direction comprises a wave shape with a series of ridges extending in parallel with each other.
4. The vehicle rocker assembly of claim 1 , wherein the ridge is a v-shaped ridge.
5. The vehicle rocker assembly of claim 1 , wherein the corrugated portion comprises alternating ridges and furrows.
6. The vehicle rocker assembly of claim 5 , wherein the furrow is a v-shaped furrow.
7. A vehicle rocker assembly comprising:
a sill inner comprising an inner wall portion, an inner upper flange portion, and an inner lower flange portion;
a sill outer comprising an outer wall portion, an outer upper flange portion, and an outer lower flange portion;
wherein the inner upper flange portion is coupled with the outer upper flange portion and the inner lower flange portion is coupled with the outer lower flange portion to define an elongated hollow interior between the inner and outer wall portions of the sill inner and the sill outer; and
a rocker insert disposed within the elongated hollow interior, the rocker insert comprising:
an upper wall,
a lower wall, and
a side wall extending between the upper wall and the lower wall, wherein at least one of the upper wall or the lower wall comprises a corrugated portion that has a ridge oriented to extend laterally between the sill inner and the sill outer, and wherein the upper wall, the lower wall, and the side wall at least partially define a tubular member extending longitudinally along the elongated hollow interior.
8. The vehicle rocker assembly of claim 7 , wherein the ridge of the corrugated portion extends continuously between the inner and outer wall portions of the sill inner and the sill outer.
9. The vehicle rocker assembly of claim 7 , wherein the side wall is coupled with the sill inner or the sill outer to support the rocker insert in the elongated hollow interior.
10. The vehicle rocker assembly of claim 7 , wherein the tubular member comprises a hollow interior that is at least partially surrounded by the upper wall, the lower wall, and the side wall.
11. The vehicle rocker assembly of claim 7 , wherein the corrugated portion is disposed on both a top surface and bottom surface of the upper wall.
12. The vehicle rocker assembly of claim 7 , wherein the corrugated portion is disposed in both a top surface and a bottom surface of the lower wall.
13. The vehicle rocker assembly of claim 7 , wherein the upper wall and the lower wall each comprise the corrugated portion and the longitudinal cross-sectional shapes of upper and lower walls comprise a wave shape defining the corrugated portion.
14. The vehicle rocker assembly of claim 7 , wherein the corrugated portion comprises a wave shape defined by alternating ridges and furrows.
15. A rocker insert for a vehicle rocker assembly having a sill inner including upper and lower flanges and a sill outer including upper and lower flanges with an elongated hollow interior defined between the sill inner and the sill outer, with the rocker insert disposed within the elongated hollow interior and comprising:
an upper wall;
a lower wall; and
a side wall extending between the upper wall and the lower wall, wherein the upper wall, the lower wall, and the side wall at least partially define a tubular member extending in a longitudinal vehicle direction, and wherein at least one of the upper wall or the lower wall comprises a corrugated portion that has a peak extending in a lateral vehicle direction between an inboard edge and an outboard edge of the respective upper or lower wall.
16. The rocker insert of claim 15 , wherein the ridge of the corrugated portion is configured to extend between the sill wall portions of the sill inner and the sill outer.
17. The rocker insert of claim 15 , wherein the side wall is coupled with the sill inner or the sill outer to support the rocker insert in the elongated hollow interior.
18. The vehicle rocker assembly of claim 1 , wherein the corrugated portion is disposed on both a top surface and a bottom surface of the upper wall, defining the corrugated portion with a thickness of the upper wall.
19. The vehicle rocker assembly of claim 1 , wherein the corrugated portion is disposed on both a top surface and a bottom surface of the lower wall, defining the corrugated portion with a thickness of the lower wall.
