Vehicle front portion structure

1. A vehicle front portion structure comprising:

a battery accommodating portion that is disposed at a vehicle lower side of a vehicle cabin, and in which a battery is to be accommodated;

a suspension member that is provided further toward a vehicle front side than the battery accommodating portion, and that has a pair of side rails that are disposed with an interval therebetween in a vehicle transverse direction and that extend in a vehicle longitudinal direction; and

connecting members that connect rear portions of the side rails and a front portion of the battery accommodating portion, and at which deforming portions that, due to input of collision load to the side rails from a vehicle front side, deform such that the rear portions of the side rails move toward a vehicle lower side with respect to the front portion of the battery accommodating portion are formed, the connecting members being formed by members having higher ductility than the side rails,

wherein:

the connecting members have front side connecting portions that are connected to the rear portions of the side rails and extend toward a vehicle rear side, and rear side connecting portions that are bent from rear ends of the front side connecting portions toward a vehicle rear and lower side,

the deforming portions are bent portions that are formed between the front side connecting portions and the rear side connecting portions,

each of the connecting members is formed as a single body, and

each of the connecting members is connected to each of the pair of side rails.

2. The vehicle front portion structure of claim 1 , wherein the side rails are manufactured by aluminum die casting.

3. The vehicle front portion structure of claim 1 , wherein the connecting members are aluminum extrusion molded products.

4. The vehicle front portion structure of claim 1 , wherein:

the battery accommodating portion has a battery frame portion that surrounds side surfaces of the battery, and

the connecting members are disposed at positions overlapping with the battery frame portion, as seen from the vehicle longitudinal direction.

5. A vehicle front portion structure comprising:

a battery accommodating portion that is disposed at a vehicle lower side of a vehicle cabin, and in which a battery is to be accommodated;

a suspension member that is provided further toward a vehicle front side than the battery accommodating portion, and that has a pair of side rails that are disposed with an interval therebetween in a vehicle transverse direction and that extend in a vehicle longitudinal direction; and

connecting members that connect rear portions of the side rails and a front portion of the battery accommodating portion, and that have front side connecting portions that are connected to the rear portions of the side rails and extend toward a vehicle rear side, and rear side connecting portions that are bent from rear ends of the front side connecting portions toward a vehicle rear and lower side,

wherein:

each of the connecting members is formed as a single body, and

each of the connecting members is connected to each of the pair of side rails.

6. The vehicle front portion structure of claim 5 , wherein the connecting members are formed by members having a ductility that is higher than that of the side rails.

7. A vehicle front portion structure comprising:

a battery accommodating portion that is disposed at a vehicle lower side of a vehicle cabin, and in which a battery is to be accommodated;

a suspension member that is provided further toward a vehicle front side than the battery accommodating portion, and that has a pair of side rails that are disposed with an interval therebetween in a vehicle transverse direction and that extend in a vehicle longitudinal direction; and

connecting members that connect rear portions of the side rails and a front portion of the battery accommodating portion, that are connected to the rear portions of the side rails and extend toward a vehicle rear side, and that have cut-out portions in upper sides of rear portions thereof,

wherein:

each of the connecting members is formed as a single body, and

each of the connecting members is connected to each of the pair of side rails.

8. The vehicle front portion structure of claim 7 , wherein the cut-out portions are between points at which the connecting members are attached to the front portion of the battery accommodating portion and the rear portions of the side rails.

9. The vehicle front portion structure of claim 7 , wherein the cut-out portions have a depth with respect to the upper side of each connecting member less than an entire thickness of the connecting members.

10. The vehicle front portion structure of claim 7 , wherein connecting members are separate from one another and are disposed with a space therebetween in the vehicle transverse direction.

11. The vehicle front portion structure of claim 7 , wherein the side rails are manufactured by aluminum die casting.

12. The vehicle front portion structure of claim 7 , wherein the connecting members are aluminum extrusion molded products.

13. The vehicle front portion structure of claim 7 , wherein the side rails comprise a die cast material and the connecting members comprise a molded material.

14. The vehicle front portion structure of claim 1 , wherein at least one of the side rails or the connecting members comprises aluminum.

15. The vehicle front portion structure of claim 1 , wherein the side rails comprise a die cast material and the connecting members comprise a molded material.

16. The vehicle front portion structure of claim 1 , wherein the connecting members are separate from one another and are disposed with a space therebetween in the vehicle transverse direction.

17. The vehicle front portion structure of claim 5 , wherein connecting members are separate from one another and are disposed with a space therebetween in the vehicle transverse direction.

18. The vehicle front portion structure of claim 5 , wherein the side rails are manufactured by aluminum die casting and the connecting members are aluminum extrusion molded products.

19. The vehicle front portion structure of claim 5 , wherein the side rails comprise a die cast material and the connecting members comprise a molded material.

20. The vehicle front portion structure of claim 5 , wherein at least one of the side rails or the connecting members comprises aluminum.
