Title:
VEHICLE BODY LOWER PART STRUCTURE
Document Type and Number:
Japanese Patent JP2020045017
Kind Code:
A
Abstract:
To obtain a vehicle body lower part structure capable of suppressing a crushing reminder during a vehicle collision in a locker with a battery pack fixed.SOLUTION: A fixing piece 45 (a fastening part 66) to which a battery pack 50 is fixed is provided inside in a vehicle width direction further than a lower vertical wall part 34 of a locker 12. That is, the locker 12 is entirely used as impact absorber during a collision of a vehicle 10 by setting the fastening part 66 of the battery pack 50 in an area B not to be crushed. Thereby, it is possible to reduce the reaction force by the locker 12 itself and accordingly reduce the weight of the locker 12. Also, the deformation of the locker 12 is not blocked by the fastening part 66 in the process of undergoing plastic deformation of the locker 12 by setting the fastening part 66 of the battery pack 50 in the area B not to be crushed. Then, a crushing reminder of the locker 12 is suppressed so that impact absorption performance can be improved during a collision of the vehicle 10.SELECTED DRAWING: Figure 1
