    • PROBLEM TO BE SOLVED: To provide a lower absorber structure of a vehicle which enables easy rigidity adjustment and shares a member between different vehicle models, thereby reducing costs for development and manufacturing.SOLUTION: A lower absorber structure of a vehicle includes: a base body 2 which is formed into a box shape having an opening 2a on a front surface and is fixed to a vehicle body; and a plate-like impact absorption member 3 which is inserted from the opening to the base body. The impact absorption member includes a rear part 2a which may be inserted into the opening of the base body and a front part 2b extending in a vehicle width direction at the front side relative to the opening of the base body. The rear part is inserted into the base body with a part at its rear end inserted into the base body.

    • PROBLEM TO BE SOLVED: To provide a leg sweeping structure for a vehicle having improved rigidity and reduced weight by that a vehicle width direction central part of the leg sweeping member improves rigidity in a cross direction because the vehicle width direction central part has small deformation quantity in a cross direction and large remaining crush stroke in a cross direction, and vehicle width direction side parts deforms by being folded in a compact manner because the parts have large deformation quantity in a cross direction and small remaining crush stroke in a cross section.SOLUTION: The leg sweeping member 40 is configured so that a longitudinal length L1 after deformation of a side part 40S with respect to light crush load is shorter than a longitudinal length L2 after deformation of a central part 40C. A fragile part 43 which serves as a folding point during light crush is extended toward a vehicle width direction. The fragile part 43 has higher rigidity in a cross direction at the central part 40C than that at the side part 40S.
    • 要解决的问题:为了提供一种具有改善的刚度和减轻重量的车辆的腿部清扫结构,由于车宽方向中心部分具有小的变形量,腿部扫掠构件的车辆宽度方向中心部分提高了横向的刚性 在十字方向上具有大的剩余挤压行程,并且车辆宽度方向侧部通过以紧凑​​的方式折叠而变形,因为部件在横截面上具有大的变形量和小的剩余挤压行程。 腿部扫掠构件40被构造为使得侧部40S相对于轻微挤压载荷变形后的纵向长度L1短于中心部40C变形后的纵向长度L2。 在轻微挤压期间用作折叠点的脆弱部分43朝向车辆宽度方向延伸。 脆性部43在中央部40C处的横方向的刚性比侧部40S的刚性高。

    • PROBLEM TO BE SOLVED: To provide an energy absorption structure which can lower a position for absorbing impact energy while also easily achieving designability without adding a complicated mechanism.SOLUTION: In an energy absorption structure 1, when a load F from a vehicle front side at a collision is applied on a lower absorber 20 through a front bumper cover 10, the load F is input to a front end part 22. Thereby, the front end part 22 moves to a vehicle rear side. Then, a rear end surface 22a of the front end part 22 abuts on a front end surface 24a of an intermediate part 24 facing through a slant slit 23. The front end surface 24a of the intermediate part 24 moves downward while sliding on the rear end surface 22a of the front end part 22, and displaces so as to rotate downward with respect to the rear end part 26 as the whole intermediate part 24. When the intermediate part 24 displaces, the intermediate part 24 is positioned so as to protrude downward from the front bumper cover 10 on a lower side from the front end part 22.
    • 要解决的问题:提供一种能够降低吸收冲击能量的位置的能量吸收结构,同时也容易实现设计性而不增加复杂的机构。解决方案:在能量吸收结构1中,当来自车辆前侧的负载F 通过前保险杠盖10在下吸收器20上施加碰撞,将负载F输入到前端部22.由此,前端部22移动到车辆后方。 然后,前端部22的后端面22a与中间部24的前端面24a相对,该中间部24面向斜切缝23。中间部24的前端面24a向后移动,同时在后端 前端部22的表面22a相对于作为整个中间部24的后端部26而向下方移动。当中间部24位移时,中间部24定位成从 前保险杠盖10在前端部22的下侧。
