Abstract

A vehicle-body front structure includes a partition wall portion which demarcates a space inside a vehicle cabin and a pair of left and right suspension tower portions which are formed to bulge inward in the vehicle width direction and support upper portions of front suspension apparatuses. A lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position. A traveling motor is installed below the lower-side portion of the partition wall portion. An upper-side portion of the partition wall portion extends from an intermediate portion of the left suspension tower portion in a vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

Claims (32)

1. A vehicle-body front structure for an electric vehicle in which a traveling motor is installed in a vehicle front portion, the vehicle-body front structure comprising:

a partition wall portion which extends in a vehicle width direction in the vehicle front portion and demarcates a vehicle cabin inside space from a power chamber; and

a pair of left and right suspension tower portions which bulge inward in the vehicle width direction and support upper portions of front suspension apparatuses,

wherein a lower-side portion of the partition wall portion is positioned further to a vehicle rear toward a lower position compared to an upper-side portion of the partition wall portion,

the traveling motor is installed below the lower-side portion of the partition wall portion, and

the upper-side portion of the partition wall portion extends from an intermediate portion of the left suspension tower portion in a vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

2. The vehicle-body front structure according to claim 1 , wherein the partition wall portion includes a first partition wall portion corresponding to the upper-side portion and a second partition wall portion corresponding to the lower-side portion, and the first partition wall portion extends from the intermediate portion of the left suspension tower portion in the vehicle front-rear direction to the intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

3. The vehicle-body front structure according to claim 2 , comprising

a motor arrangement portion which is formed by causing a part of the second partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of the traveling motor is capable of being arranged.

4. The vehicle-body front structure according to claim 3 , wherein

the first partition wall portion is provided with a partition wall reinforcement member which extends in the vehicle width direction.

5. The vehicle-body front structure according to claim 4 , wherein

front wheel wells which bulge to vehicle-width-direction inner sides are continuous with vehicle rear sides of the left and right suspension tower portions, and

both sides of the second partition wall portion in the vehicle width direction are connected with the left and right front wheel wells.

6. The vehicle-body front structure according to claim 5 , comprising

a pair of left and right side sills which extend in the vehicle front-rear direction in both end portions of a floor panel in the vehicle width direction, wherein

the second partition wall portion extends to the vehicle rear to reach the left and right side sills and is connected with the left and right side sills.

7. The vehicle-body front structure according to claim 2 , wherein

front wheel wells which bulge to vehicle-width-direction inner sides are continuous with vehicle rear sides of the left and right suspension tower portions, and

both sides of the second partition wall portion in the vehicle width direction are connected with the left and right front wheel wells.

8. The vehicle-body front structure according to claim 2 , comprising

a pair of left and right side sills which extend in the vehicle front-rear direction in both end portions of a floor panel in the vehicle width direction, wherein

the second partition wall portion extends to the vehicle rear to reach the left and right side sills and is connected with the left and right side sills.

9. The vehicle-body front structure according to claim 3 , wherein

front wheel wells which bulge to vehicle-width-direction inner sides are continuous with vehicle rear sides of the left and right suspension tower portions, and

both sides of the second partition wall portion in the vehicle width direction are connected with the left and right front wheel wells.

10. The vehicle-body front structure according to claim 3 , comprising

a pair of left and right side sills which extend in the vehicle front-rear direction in both end portions of a floor panel in the vehicle width direction, wherein

the second partition wall portion extends to the vehicle rear to reach the left and right side sills and is connected with the left and right side sills.

11. The vehicle-body front structure according to claim 4 , comprising

a pair of left and right side sills which extend in the vehicle front-rear direction in both end portions of a floor panel in the vehicle width direction, wherein

the second partition wall portion extends to the vehicle rear to reach the left and right side sills and is connected with the left and right side sills.
