Structural assembly having integrated outer and inner reinforced members
View Patent ↗A structural assembly, such as for use as a rocker panel in an automotive vehicle and which includes an outer rocker cover and an inner attached and reinforcing member. The reinforcing member is constructed from a continuous steel grade and roll formed material and includes first and second spaced apart wall portions which converge at upper and lower extending ends. An integrally formed web interconnects the inner and outer portions at the lower extending end and exhibits a bulbous shaped configuration defined by an inner radius. Drainage holes are formed through bottommost facing locations of said web, at preselected distances along its length, and in order to evacuate water and paint.
1. A structural assembly, comprising:
a three-dimensional shaped and elongated cover, said cover exhibiting, in cross section, opposite outer and inner facing surfaces along its extending length, and upper and lower extending ends separated by an arcuately extending middle section;
a reinforcing member secured along said inner facing surface of said three-dimensional shaped cover, said reinforcement member including first and second spaced apart wall portions terminating along upper and lower extending ends; and
said lower extending end of said reinforcing member including an integrally formed web interconnecting converging locations of said first and second wall portion, said web exhibiting an open interior defined by a given radius.
2. The structural assembly as described in claim 1 , at least one of said cover and said reinforcing member being constructed of a roll formed material.
3. The structural assembly as described in claim 2 , further comprising said reinforcing member having a specified shape and size and being roll formed from a single sheet in a closed profile, prior to being cut to length.
4. The structural assembly as described in claim 2 , further comprising said reinforcing member having a specified shape and size and being roll formed to achieve a lower strength profile while hardening and subsequently reformed to a final three-dimensional shape.
5. The structural assembly as described in claim 1 , further comprising a gap defined between said converging locations of said first and second wall portions during roll forming of said reinforcing member.
6. The structural assembly as described in claim 2 , wherein said radially spaced configuration associated with said web creates a spring bias to maintain, in proximate position, said upper ends of said first and second spaced apart wall portions.
7. The structural assembly as described in claim 6 , said radially spaced configuration having a specified shape and size and further comprising a substantially bulbous and elongated shape.
8. The structural assembly as described in claim 1 , further comprising at least one drainage aperture defined at a lower extending location along said reinforcing member.
9. The structural assembly as described in claim 8 , further comprising a plurality of scallop shaped apertures formed into said open interior radius associated with said web.
10. The structural assembly as described in claim 1 , said cover and reinforcing member each further exhibiting a specified shape and size, further comprising at least one of welds, adhesives or mechanical fasteners for securing said reinforcing member to said inner extending surface of said elongated and three-dimensional shaped cover.
11. The structural assembly as described in claim 1 , said reinforcing member being roll formed from a continuous length of a steel grade material and further comprising a longitudinally extending and recessed portion integrally formed within each of said first and second spaced apart wall portions, said recessed portions exhibiting at least one of a step, bead or ribbed shape for imparting strength to said reinforcing member.
12. A rocker panel assembly incorporated into a vehicle, comprising:
an elongated and three-dimensional shaped rocker panel cover, said rocker panel exhibiting, in cross section, opposite outer and inner facing surfaces along its extending length, and upper and lower extending ends separated by an arcuately extending middle section;
a reinforcing inner member secured along said inner facing surface of said three-dimensional shaped rocker panel cover, said reinforcement member including first and second spaced apart wall portions terminating along upper and lower extending ends;
said lower extending end of said reinforcing member including an integrally formed web interconnecting converging locations of said first and second wall portion, said web exhibiting an open interior defined by a given radius; and
a gap defined between said converting locations of said first and second wall portions during a roll forming process associated with said reinforcing member.
13. The rocker panel assembly as described in claim 12 , said radially spaced configuration having a specified shape and size and further comprising a substantially bulbous and elongated shape.
14. The rocker panel assembly as described in claim 12 , further comprising at least one drainage aperture defined at a lower extending location along said reinforcing member.
15. The rocker panel assembly as described in claim 12 , further comprising a plurality of scallop shaped apertures formed into said open interior radius associated with said web.
16. The rocker panel assembly as described in claim 12 , said rocker panel cover and reinforcing member each further exhibiting a specified shape and size, further comprising at least one of welds, adhesives or mechanical fasteners for securing said reinforcing member to said inner extending surface of said elongated and three-dimensional shaped cover.
17. The rocker panel assembly as described in claim 12 , said reinforcing member being roll formed from a continuous length of a steel grade material and further comprising a longitudinally extending and recessed portion integrally formed within each of said first and second spaced apart wall portions, said recessed portions exhibiting at least one of a step, bead or ribbed shape for imparting strength to said reinforcing member.
