20100096887 | VEHICLE FRONT SIDE MEMBER - A member of a vehicle frame structure includes an extension portion that extends in a longitudinal direction and a kick portion positioned behind, and below the extension portion. Buckling lines are formed in parallel with each other in the extension portion, and each of the buckling lines is inclined such that a lower end is positioned ahead of an upper end in a side view. If a collision load is applied from a front side of a vehicle at the time of vehicle collision, the extension portion is deformed along the buckling lines, and a front end of the extension portion is displaced downward. Therefore, a vertical offset between the front end of the extension portion and the kick portion is reduced, thereby reducing a bending moment applied to the kick portion. Accordingly, the required yield strength of the kick portion can be set to a lower value. | 04-22-2010 |

The neutral axis of the bend is disposed in the vicinity of the compression-side wall part. For example, the compression-side wall part is higher in material strength, and/or larger in sheet thickness, than the tension-side wall part. | 06-03-2010 |

20110254320 | VEHICLE BODY SIDE STRUCTURE - A rocker includes a lower wall portion, which is an inclined surface inclined downward toward the inside of a vehicle body, on the lower surface of the rocker, and a floor panel is bonded to the lower wall portion. Accordingly, when an in-plane tensile force is applied to the floor panel the in-plane tensile force is applied not in a direction where the bonding between the rocker and the floor panel is separated but in a direction where the bonding between the rocker and the floor panel is shorn. As a result, it may be possible to improve bonding strength. Further, a corner portion is formed at the end portion of the inclined surface facing the floor panel, and a frictional force is generated at the corner portion between the floor panel and the rocker. Therefore, a load, which is applied to the floor panel, can be distributed to the rocker. Due to these operations, reinforcing members and the like do not need to be provided, and it may be possible to improve the bonding strength between the rocker and the floor panel. | 10-20-2011 |

The upper floor member and the flat portion of the floor panel are connected to each other by being respectively welded to brackets. A floor cross member extending in the width direction of the vehicle is fixed to the flat portion across the groove. | 02-16-2012 |
20120152675 | SHOCK ABSORBING STRUCTURE - There is provided a shock absorbing structure that can improve shock absorption performance by stabilizing the compressive deformation of a shock absorbing member in an axial direction. High-strength portions controlling deformation and low-strength portions controlling deformation are alternately disposed. Accordingly, when a shock is applied to a front side member from the front side of a vehicle, the front side member can be deformed in the shape of a bellows. Further, the respective low-strength portions, which are disposed closer to a rear end side in a longitudinal direction, have higher strength. Therefore, the front side member can be sequentially deformed from a front end side. | 06-21-2012 |
