OCR07AP1. The undercarriage structure of the vehicle incorporating the battery; and the energy absorption components positioned in the width direction of the vehicle outside the battery, the energy absorption components are formed into a closed cross-section that extends in the width direction of the vehicle when viewed from the front-rear direction of the vehicle, where the energy absorption components are configured to include: an upper wall configured at the upper end in the height direction of the closed cross-section, a lower wall configured at the lower end in the height direction of the closed cross-section, and more than one vertical bulkhead separating the inside of the closed cross-section, between the upper and lower walls.In the direction of the vehicle width to form more than one free space; and where the free space in the direction of the vehicle width from the outermost free space arranged in the direction of the outer vehicle width towards the free space free space is arranged in an alternating manner with: a pair of indentations, one in the lower surface of the upper wall indented toward the top of the vehicle of the free space and in the upper surface of the lower wall indented toward the bottom of the vehicle of the free space, or a pair of indentations, the second in the upper surface of the upper wall indented toward the bottom of the vehicle of the free space and in the lower surface of the lower wall indented toward the top of the vehicle of the free space; 2. The undercarriage structure of the vehicle of claim 1, where the first pair of indentations is arranged at the outermost free space; 3. The undercarriage structure of the vehicle of claim 1,Where: the energy-absorbing components, including side bulkheads, are provided to separate the interior of the enclosed cross-section by dividing the top / bottom of the vehicle; and a third indentation located in the upper surface of the side bulkhead that collapses toward the bottom of the vehicle or in the lower surface of the side bulkhead that collapses toward the top of the vehicle, is provided at the empty space where a pair of the first or second indentation is formed.

4. Undercarriage of the vehicle under claim 3, where: the undercarriage of the vehicle is further incorporated with support elements provided for the battery, support elements that support the energy-absorbing components, support elements including retaining walls that form part of the support elements to which the energy-absorbing components provided in the width direction of the vehicle are attached, and retaining walls and side bulkheads overlap in the height direction of the vehicle.

5. Undercarriage of the vehicle under claim 3, where, for the adjacent empty space in the width direction of the vehicle, the top wall, the bottom wall, and the side bulkheads,6. Underbody structure of claim 4, where: Energy absorption components including side walls are provided inside a closed cross-section to divide more than one space by dividing the upper / lower of the vehicle respectively into upper and lower spaces, and the position corresponding to the innermost upper space provided on top of the vehicle of the innermost lower space provided in the inner width direction of the vehicle is cut off, and support components are provided in the position corresponding to the innermost upper space.

7. Underbody structure of claim 3, where: Energy absorption components including side walls are provided inside a closed cross-section to divide more than one space by dividing the upper / lower of the vehicle respectively into upper and lower spaces,and the height dimension in the direction of the vehicle's height of the lower space is greater than the height dimension of the upper space, and the height dimension of the lower space is greater than the width dimension in the direction of the vehicle's width of the upper space.

8. The undercarriage structure of the vehicle in claim 7, where a third indentation is formed on the lower surface of the sidewall at a position corresponding to the first pair of indentations, and is formed on the upper surface of the sidewall at a position corresponding to the second pair of indentations.

9. The undercarriage structure of the vehicle in claim 3, which is further incorporated with: side frames extended in the forward-rear direction of the vehicle, side frames positioned in the width direction of the vehicle outside the battery; and curved beams extended in the forward-rear direction of the vehicle, curved beams positioned in the width direction of the vehicle outside the side frame, where the energy absorption component extends in the width direction of the vehicle outside at the bottom in the height direction of the vehicle of the side frame.

10. The undercarriage structure of the vehicle in claim 9,Where a pair of the first or second indentations are provided on the upper and lower walls, and a third indentation is provided on the side bulkhead, these are placed on the outer open space further away in the width direction of the outer vehicle than the side frame; the side frame extends in the front-rear direction of the vehicle and is positioned in the width direction of the outer vehicle of the battery;
