Title:
ROCKER PART STRUCTURE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2019014357
Kind Code:
A
Abstract:
To reduce the weight of a rocker part without reducing collision safety performance and body rigidity even if the height of a closed cross-section of only a portion provided at a lower edge of a rear-side door opening of the rocker part is decreased.SOLUTION: The height of a closed cross-section of a portion 12 of a rocker part 1 disposed at a lower edge of a rear-side door opening is set lower than the height of a closed cross-section of the other portion 13 of the rocker part. In the intermediate of the rocker part, a gradual change section 14 in which the height of a closed cross-section gradually changes is provided. Inflection points 14a, 14b formed at both ends of the gradual change section are joined to a B pillar so as to be accommodated in forward and backward directions of the vehicle and in a B pillar 7 extended in a vertical direction of the vehicle. At a portion 12 lower in the height of a closed cross-section, a share panel 4 for restricting deformation of a lower portion of the rocker part is sandwiched by a joint between a rocker outer reinforcement 2 formed from a super high-tensile steel plate with a tensile strength of 1180 MPa and a rocker inner reinforcement 3 in forward and backward directions of the vehicle.SELECTED DRAWING: Figure 1
