Abstract
An energy management system and device (10) for use in an automotive frame, rail, or other structural component of an automotive vehicle. The frame or rail (16) having a cavity or exposed surface capable of supporting at least one member. The member (12) having an interior portion and an exterior portion with the interior portion being defined by at least one trigger or step change (20) to the geometry of the inner portion to target and direct axial bending of the system. An expandable material (14), such as a polymer-based foamable material, is disposed along the exterior portion of a member prior to final assembly of the vehicle by the vehicle manufacturer. The system is activated as the vehicle undergoes the final vehicle assembly process and paint operation which activates and transforms the expandable material to expand, bond and structurally adhere the frame rail to mange, direct, and/or absorb energy in the event of an impact to the vehicle an applied load or an external force.
Claims (18)
1. A structural reinforcing system (10) for reducing and inhibiting distortion characteristics of an automotive vehicle in the event of impact from an external force, comprising:
a) at least one reinforcing member (12); (21) having an interior and an exterior portion adapted for placement in a cavity disposed in an automotive frame assembly; and containing at least one weak point (20) comprising a change or discontinuity in the geometry of the member along said interior portion of said member and b) an expandable material (14), (22), (23) (24) disposed over at feast a portion of said member.
a) at least one reinforcing member (12); (21) having an interior and an exterior portion adapted for placement in a cavity disposed in an automotive frame assembly; and containing at least one weak point (20) comprising a change or discontinuity in the geometry of the member along said interior portion of said member and b) an expandable material (14), (22), (23) (24) disposed over at feast a portion of said member.
2. The system as claimed in Claim 1, wherein said member comprises a plurality of weak point (20).
3. The system as claimed in Claim 1 or Claim 2, wherein said member is adapted for reinforcing portions of an automotive vehicle selected from the group consisting of a rail member, a frame member, a door assembly, a rocker, and a frame cross member.
4. The system as claimed in Claim 1 or Claim 2, wherein said member is adapted for reinforcing portions of an automotive vehicle selected from the group consisting of a vehicle window frame, a vehicle deck lid, a lift gate, a vehicle pillar assembly, and a vehicle hatch.
8. The system as claimed in Claim 1 or Claim 2, wherein said member is adapted for reinforcing portions of an automotive vehicle selected from the group consisting of a vehicle roof system, a roof bow, a roof rail, and a roof header.
6. The system as claimed in Claim 1 or Claim 2, wherein said member is adapted for reducing impact energy deformation of portions of an automotive vehicle selected from the group consisting of a fender assembly, a bumper, and a front end structure.
7. The system as claimed in any of the preceding Claims, wherein said member is comprised of a material selected from the group consisting of extruded aluminum, an aluminum foam, a magnesium alloy, a molded magnesium alloy, a magnesium foam, a titanium alloy, a molded titanium alloy, and a titanium foam.
8. The system as claimed in any of the preceding Claims, wherein said member is comprised of a material selected from the group consisting of a stamped and formed cold rolled steel, a stamped and formed high strength low alloy steel, a roll formed cold rolled steal, and a roll formed high strength low alloy steel.
9. The system as claimed in any of the preceding Claims wherein said member comprises:
a) a first portion (12) suitable for placement within a defined portion of an automotive vehicle; and b) a second portion (12) contiguous with said first portion, said second portion having a surface adapted for carrying an expandable material (14), which upon expansion helps absorb and distribute impact energy over said surface in response to said load.
a) a first portion (12) suitable for placement within a defined portion of an automotive vehicle; and b) a second portion (12) contiguous with said first portion, said second portion having a surface adapted for carrying an expandable material (14), which upon expansion helps absorb and distribute impact energy over said surface in response to said load.
10. The system as claimed in Claim 9; wherein said member further comprises a third portion contiguous with one of said first and second portions, said third portion containing a plurality of weak points.
11. A system as claimed in any of Claims 1 to 10, wherein said expandable material is a polymeric material having foamable characteristics.
12. A system as claimed in Claim 11, wherein said expandable material is an epoxy-based polymeric material having foamable characteristic.
13. A system as claimed in Claim 10 or Claim 11, wherein said expandable material is a heat activated expandable polymer material.
14. A system as claimed in any of Claims 1 to 13, wherein said expandable material is an expandable plastic material that is generally free of tack to the touch.
15. A system as claimed in any of Claims 1 to 14, wherein said expandable material is an expandable plastic material that can be activated at a temperature encountered in an automotive vehicle paint operation.
16. A frame rail (16) suitable for use as a structural member in an automotive vehicle, said frame rail having an exposed surface portion and containing a structural reinforcing system according to any of the preceding Claims wherein the member is mountingly engaged to said exposed surface portion of said frame rail.
17. A frame rail (16) as claimed in Claim 16, wherein said expandable material is an ethylene polymer-based polymer foam.
18. A frame rail (16) according to Claim 16 or Claim 17 having an inner portion and an outer portion defining a cavity therein wherein the structural reinforcing member (12) is placed within said frame member and the expandable material (14) is in sealing contact with said member (16), and is suitable for expansion upon exposure to heat to thereby bond said member to at least one of said inner portion and said outer portion of said frame rail.
