Abstract

A vehicle-front body structure includes a partition wall portion which demarcates a vehicle cabin inside space, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, a cross member which is fixed to a floor panel on a vehicle rear side of the motor arrangement portion and extends in a vehicle width direction, and a reinforcement member which couples the motor arrangement portion and the cross member together.

Claims (45)

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 separates a vehicle cabin inside space;

a motor arrangement portion which is a part of the partition wall portion, the motor arrangement portion bulges to an inside of the vehicle cabin inside space and at least a part of the traveling motor that is installed on an outside of the vehicle cabin inside space is arranged on the motor arrangement portion;

a cross structure which is fixed to a floor panel on a vehicle rear side of the motor arrangement portion and extends in the vehicle width direction; and

a reinforcement structure which couples the motor arrangement portion and the cross structure together.

2 . The vehicle-body front structure according to claim 1 , wherein

a battery which supplies electric power to the traveling motor is arranged, below the floor panel, rearward of a front portion of the reinforcement structure.

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

in a front view, at least a part of the traveling motor is positioned so as to overlap with a front portion of the reinforcement structure.

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

a battery casing housing the battery,

a front-side battery frame which extends in the vehicle width direction is provided in a front portion of the battery casing, and

in the front view, at least a part of the traveling motor is positioned so as to overlap with at least a part of the front-side battery frame.

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

a lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position, and

the traveling motor is installed in the motor arrangement portion which is formed in the lower-side portion of the partition wall portion.

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

at least a part of a seat which is disposed in the vehicle cabin inside space is mounted on the cross structure.

7 . The vehicle-body front structure according to claim 1 , wherein

in a front view, at least a part of the traveling motor is positioned so as to overlap with a front portion of the reinforcement structure.

8 . The vehicle-body front structure according to claim 1 , wherein

a battery casing housing a battery supplying electric power to the traveling motor is disposed below the floor panel,

a front-side battery frame which extends in the vehicle width direction is provided in a front portion of the battery casing, and

in a front view, at least a part of the traveling motor is positioned so as to overlap with at least a part of the front-side battery frame.

9 . The vehicle-body front structure according to claim 1 , wherein

a lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position, and

the traveling motor is installed in the motor arrangement portion which is formed in the lower-side portion of the partition wall portion.

10 . The vehicle-body front structure according to claim 1 , wherein

at least a part of a seat which is disposed in the vehicle cabin inside space is mounted on the cross structure.

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

a battery casing housing the battery,

a front-side battery frame which extends in the vehicle width direction is provided in a front portion of the battery casing, and

in a front view, at least a part of the traveling motor is positioned so as to overlap with at least a part of the front-side battery frame.

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

a lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position, and

the traveling motor is installed in the motor arrangement portion which is formed in the lower-side portion of the partition wall portion.

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

at least a part of a seat which is disposed in the vehicle cabin inside space is mounted on the cross structure.

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

a lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position, and

the traveling motor is installed in the motor arrangement portion which is formed in the lower-side portion of the partition wall portion.

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

at least a part of a seat which is disposed in the vehicle cabin inside space is mounted on the cross structure.

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

at least a part of a seat which is disposed in the vehicle cabin inside space is mounted on the cross structure.
