Title:
BUMPER REINFORCEMENT
Document Type and Number:
Japanese Patent JP2018176889
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To relatively weaken the strength (rigidity) of a front face plate portion to which collision load of a reinforcement member is applied compared to strength in other portions by dividing the reinforcement member at support plate portions, and thus prevent or suppress generation of stress concentration and buckling caused by the stress concentration.SOLUTION: A reinforcement member 30 having a trapezoidal cross section comprises a front side reinforcement body 40 and a rear side reinforcement body 50, and is divided at positions of an upper support plate portion 30E and a lower support plate portion 30F. By weakening the strength (rigidity) of the front side reinforcement body 40, the strength (rigidity) of a front face plate portion 30A to which collision load is applied is weakened compared to the strength in other portions, so as to prevent or suppress generation of stress concentration and buckling caused by the stress concentration.SELECTED DRAWING: Figure 4
