  • Patent number: 11027682
    Abstract: A front portion structure of a vehicle includes a front bumper R/F, a side member, and a crush box inserted between the front bumper R/F and the side member, the side member having a first region connected to the crush box and a second region extending from a rear end of the first region, in which a vehicle-widthwise outer side surface of the first region is at a position being bent with respect to a vehicle-widthwise outer side surface of the crush box so as to form a protrusion protruding vehicle-widthwise outward, and a vehicle-widthwise outer side surface of the second region is at a position being bent from the vehicle-widthwise outer side surface of the first region so as to form a protrusion protruding vehicle-widthwise inward, and a reinforcement plate is joined to the vehicle-widthwise outer side surface in the first region.

  • Patent number: 9902350
    Abstract: An upper and lower pair of first beads that extend in a longitudinal direction are formed at an inner side wall of a front side spacer. The first beads project to the vehicle width direction outer side. Therefore, when a collision load diagonally to the rear-left side is inputted to a front end portion of the inner side wall, the first beads act to support the inner side wall adjacent above and below the first beads from the vehicle width direction outer side. Accordingly, tilting deformation of the inner side wall toward the vehicle width direction outer side at the beginning of a micro-wrap collision of a vehicle is suppressed. An overall dimension in the vertical direction of the general portions of the inner side wall is specified to be greater than an overall dimension in the vertical direction of the first beads.
