AI Technical Summary

Technical Problem

Existing vehicle side structures face a compromise between weight and strength, requiring a design that balances rigidity for impact resistance with the ability to deform and absorb energy during collisions.

Method used

The vehicle side structure incorporates longitudinally extending side portions with first and second members attached to form a closed space, along with first and second reinforcing members. These reinforcing members have corrugated legs with ridges and grooves, extending from head sections to feet, and are attached to each other to enhance deformation and stiffness.

Benefits of technology

The innovative reinforcement members improve the vehicle side structure's ability to absorb impacts and energy while maintaining or enhancing stiffness and reinforcement, reducing weight and cost, and improving collision performance.

Abstract

A vehicle side structure (102; 202) includes a side portion (104; 204) extending in a longitudinal direction (106; 206), the side portion (104; 204) including a first member (108; 208) extending in the longitudinal direction (106; 206) and a second member (110; 210) extending in the longitudinal direction (106; 206). The first member (108; 208) is configured to face an interior side (112; 212) of the vehicle, and the second member (110; 210) is configured to face an exterior side (114; 214) of the vehicle. The first member (108; 208) and the second member (110; 210) are attached to each other to form a substantially closed space (116; 216) therebetween. The side portion (104; 204) comprises two corrugated reinforcing members (118, 120; 218, 220) located in the substantially closed space (116; 216). The reinforcing members (118; 218) and (120; 220) are attached to each other.
