Storage box for a pickup truck formed from metallic and composite materials
View Patent ↗A storage box for a pickup truck or similar vehicle is formed from a combination of metallic and composite materials. The storage box includes an internal storage box frame that is formed from a plurality of metallic tubular components that are secured together, such as by magnetic pulse welding techniques. The metallic tubular pieces can be formed from steel, aluminum, and the like, or any combination thereof. The storage box further includes one or more panels that are formed from composite materials, such as urethane, that are secured to the metallic storage box frame. The composite panels may secured to the metallic storage frame box by molding the composite material directly about the metallic storage box frame. Alternatively, the composite panels may be formed as separate pieces that are connected to the metallic storage box frame. The combination of the internal metallic storage box frame and the external composite storage box panels provides a relatively light weight storage box that is resistant to dents and other deformations during use.
1. A storage box for a vehicle comprising:
a storage box frame that is formed from a plurality of metallic components that are secured together in a preformed frame of the interconnected metallic components, each component having a cross-sectional shape; and
one or more panels including an outer surface and an inner surface that are formed from composite materials, sized and shaped to conform to the cross-sectional shape of portions of the storage box frame, and molded directly about the metallic storage box frame, the outer surface having a desired shape of an outer surface of the storage box, the inner surface having a desired shape of an inner surface of the storage box.
2. The storage box defined in claim 1 wherein said storage box frame is formed from a plurality of metallic tubular components.
3. The storage box defined in claim 1 wherein said plurality of metallic components are secured together by magnetic pulse welding.
4. The storage box defined in claim 1 wherein said composite panel is formed as a separate piece that is molded directly about the metallic storage box frame.
5. The storage box defined in claim 1 wherein a plurality of said composite panels are formed as separate pieces that are molded directly about the metallic storage box frame.
6. The storage box defined in claim 1 wherein the composite material is urethane foam.
7. The storage box defined in claim 1 wherein the composite material is urethane foam reinforced with glass fibers.
8. The storage box defined in claim 1 wherein the panels and frame form lateral surfaces of the storage box.
9. A storage box for a vehicle comprising:
a storage box frame that is formed from a plurality of metallic components that are secured together in a preformed frame of the interconnected metallic components, each component having a cross-sectional shape; and
first and second panels that are each formed from a composite material and are sized and shaped to conform to the cross-sectional shape of portions of the storage box frame, and secured to the metallic storage box frame;
the first panel including the outer surface and a intermediate surface formed with a first recess that is sized and shaped to receive a portion of the cross-sectional shape of the storage box frame within the first recess; and
the second panel including the inner surface and a second intermediate surface formed with a second recess facing the first recess, sized and shaped to receive a second portion of the cross-sectional shape of the storage box frame within the second recess;
wherein the outer surface having a desired shape of an outer surface of the storage box, an inner surface having a desired shape of an inner surface of the storage box.
10. The storage box defined in claim 9 wherein said storage box frame is formed from a plurality of metallic tubular components.
