    • 【課題】車体前部の低い位置に配設される保護部材によって、障害物の車体下部へ侵入防止と、衝突時のエネルギ吸収と、その後の障害物の前方への跳ね上げ作用とを得る。【解決手段】保護部材10が、左右一対のサイドフレーム1の前部から下方かつ前方に傾斜して伸びる左右一対のブラケット11、およびバンパビーム3の下方において車幅方向に伸びると共に、左右一対のブラケット11の前端に取付けられたスティフナ12を有する。保護部材10は、前方障害物に対する衝突時における衝突荷重と変形量との関係を示す荷重・変形特性の設定によって、衝突初期時からの第1段階では障害物が車体前部の下方への侵入抑制作用を行い、続く第2段階では障害物の局部変形を抑制すべくエネルギ吸収作用を行い、その後の第3段階では障害物を車体前方に跳ね上げる作用を行う。【選択図】図9
    • 要解决的问题:为了提供一种车辆的前部车体结构,包括设置在车体前部的下部位置并且防止障碍物进入车体下部的保护构件 碰撞时吸收能量,以及在碰撞之后将障碍物向前方翻转的动作。解决方案:车辆的前车体结构包括保护构件10.保护构件10包括:一对右/左支架 11,其从左右侧框架1的向前下方倾斜的前部延伸; 在缓冲梁3的下侧沿车辆宽度方向延伸的加强件12,并且安装在支架11的前端。通过设定表示缓冲载荷与变形量之间的关系的载荷/变形特性 与前方障碍物的碰撞,保护构件10执行:在碰撞的第一阶段,抑制障碍物侵入车身前方的入侵抑制动作; 抑制第二阶段的障碍物的局部变形的能量吸收动作; 以及在第三阶段向障碍物朝向车体的前方向翻转的翻转动作。

    • PROBLEM TO BE SOLVED: To improve a protection characteristic against an occupant and secure a wide foot space of the occupant to improve comfort by restricting the entering of a front panel into a driver's room when the vehicle collides at is front (including a head-on collision and an offset collision), in a vehicle body front structure of a cab-over vehicle.
      SOLUTION: A substantial hat-shaped reinforcing member 27 as viewed in an upward or downward section and other members arranged along a front panel 5 in an upward or downward direction are installed at a compartment of a part at least opposing a front seat 9 of the front panel 5. The upper end of the reinforcing member 27 is connected to a cross member 33 arranged in a vehicle width direction in the compartment and in turn, the lower end 27U of the reinforcing member 27 is extended to a location near a floor panel 17 and connected to a bracket member 39. The bracket member 39 is also connected to either a side frame 23 or a second cross member 35.

    • PROBLEM TO BE SOLVED: To restrict the injury of lower legs of an occupant seated at a front part of a vehicle at the time of a front collision while restricting an increase in the weight of a bumper reinforcement of a vehicle body front structure of a cab-over vehicle.
      SOLUTION: A bumper reinforcement 19 has a height position where its upper end substantially corresponds to legs of an occupant as seen in a front view of the vehicle and a width up to a front part of a door hinge pillar 25L near a shock absorbing frame 21 from the inside of the vehicle width direction of the shock absorbing frame 21. The bumper reinforcement 19 is arranged at at least either of right and left sides as seen in the forward or rearward direction of the vehicle, its inside portion in the vehicle width direction is connected to the shock absorbing frame 21, and its outside portion in the vehicle width direction is connected to stay members 27a, 27b extended from the door hinge pillar 25L in a forward direction. In addition, the bumper reinforcement 19 has several openings K1 processed by burring to reduce its weight.
