摘要： A protecting member includes a pair of right-and-left brackets which extend obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener which extends in a vehicle width direction below a bumper beam and attached to front ends of the pair of right-and-left brackets. The protecting member has a load/deformation characteristic including a first stage from a collision start, a second stage after the first stage, and a third stage after the second stage. Herein, the first stage is set so as to restrain the obstacle from coming in below a vehicle-body front portion, the second stage is set so as to absorb collision energy to restrain a local deformation of the obstacle, and the third stage is set so as to flick the obstacle up.

摘要： A protecting member comprises a pair of right-and-left brackets extending obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener extending in a vehicle width direction below a bumper beam and attached to front ends of the brackets. The stiffener has a closed cross section extending in the vehicle width direction, and an upper face of its central portion in the vehicle width direction has a concaved portion. A lower face of the stiffener extends horizontally substantially straightly. It is preferable that the closed cross section of the central portion of the stiffener be configured such that its vertical distance is relatively small and its longitudinal width is relatively large, compared with the other part of the stiffener.

摘要： A pair of right-and-left brackets which extend obliquely downward and forward from respective front portions of a pair of right-and-left side frames are provided. A stiffener which extends in a vehicle width direction below a bumper beam is attached to respective front ends of the pair of right-and-left brackets. The stiffener is configured such that its front end portion slants downward and forward and has an open cross section, and its rear end portion thereof has a closed cross section. An obstacle can be prevented from coming in below a vehicle-body front portion, and also the sufficient energy absorption in a collision and the prompt flicking-up of an obstacle can properly achieved.
摘要翻译：提供了一对左右侧支架，其从左右一对侧框架的各自的前部向下方倾斜地向前方延伸。在保险杠梁下方的车宽方向上延伸的加强件连接到该对左右支架的相应前端。加强件的构造使得其前端部向下并向前倾斜并且具有开放的横截面，并且其后端部具有闭合的横截面。可以防止障碍物进入车身前部的下方，并且可以适当地实现碰撞中足够的能量吸收和障碍物的迅速扑灭。

摘要： Provided is an automobile front body structure configured such that a reinforcement member is joined to a cowl panel. The cowl panel includes an upper surface portion, a forwardly bulging portion, a rearwardly bulging portion, and a lower surface portion. The reinforcement member includes a reinforcement member body which has a substantially squared U-shaped section which is bent and extends along the cowl panel, a first joint portion and a second joint portion. The reinforcement member body includes a wide portion of a substantially squared U-shaped section which is wide in the vehicle width direction and extending along the forwardly bulging portion, and a narrow portion such that a substantially squared U-shaped section is narrowed in the vehicle width direction toward the vehicle lower side. A sectional depth of the narrow portion is larger than a sectional depth of the wide portion.

摘要： A panel joint structure suppresses stress concentration on a flange corner section-side end-portion of an adhesive during application of a peeling load. A first panel member includes a panel body section, a corner section, and a first flange section. A second panel member is arranged to oppose the first flange section. A joint section joins the first flange section and the second panel member in a contact state thereof, and an adhesive continuously provided in a longitudinal direction of the corner section adheres the first flange section to the second panel member. The first panel member includes a load transmission section near a joint section, and the load transmission section is provided between the panel body section and the first flange section, and an angle θ2 thereof that is defined with the panel body section is larger than an angle θ1 defined by the panel body section and a portion in a short direction of the first flange section. A flange distal end-side end-portion of the load transmission section in the short direction of the flange section is disposed in a region between a corner section-side end-portion and a distal end-side end-portion of the joint section in the short direction of the first flange section.
