Abstract

To suppress deformation of a vehicle cabin by efficiently absorbing an impact load obliquely from a vehicle front side, a vehicle-body front structure includes an upper-side cross member, a lower-side cross member, upper-side impact absorption members that support respective ones of both vehicle-width-direction sides of the upper-side cross member, and lower-side impact absorption members that support respective ones of both vehicle-width-direction sides of the lower-side cross member. The upper-side impact absorption members and the lower-side impact absorption members are each positioned farther on a vehicle-width-direction outer side at a position farther on a vehicle front side.

Claims (51)

1. A vehicle-body front structure of an automobile including a bumper reinforcement extending in a vehicle width direction, the vehicle-body front structure, comprising:

an upper-side cross member extending in the vehicle width direction on an upper side of the bumper reinforcement;

a lower-side cross member extending in the vehicle width direction on a lower side of the bumper reinforcement;

upper-side impact absorption members that each support one of both vehicle-width-direction sides of the upper-side cross member and absorb an impact load in a vehicle front-rear direction; and

lower-side impact absorption members that each support one of both vehicle-width-direction sides of the lower-side cross member and absorb an impact load in the vehicle front-rear direction, wherein

the upper-side impact absorption members and the lower-side impact absorption members are each positioned farther on a vehicle-width-direction outer side at a position farther on a vehicle front side.

2. The vehicle-body front structure according to claim 1 , further comprising:

a rear-portion connecting portion that connects vehicle rear sides of at least either of the upper-side impact absorption members and the lower-side impact absorption members to a vehicle-body side member, wherein

the rear-portion connecting portion includes a reinforcement portion formed along a sidewall portion of the impact absorption member on one vehicle-width-direction side.

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

the upper-side cross member and the lower-side cross member extend further on the vehicle-width-direction outer side than the bumper reinforcement, and

vehicle front sides of the upper-side impact absorption members and the lower-side impact absorption members are positioned farther on the vehicle-width-direction outer side than the bumper reinforcement.

4. The vehicle-body front structure according to claim 3 , further comprising:

crush cans that each support one of both vehicle-width-direction sides of the bumper reinforcement, wherein

vehicle front sides of the upper-side impact absorption members and the lower-side impact absorption members are positioned on the vehicle-width-direction outer side of vehicle front sides of the crush cans.

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

vehicle rear sides of the crush cans are separated downward from vehicle rear sides of the upper-side impact absorption members, and

vehicle rear sides of the lower-side impact absorption members are separated downward from the vehicle rear sides of the crush cans.

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

a traveling motor;

a battery that is disposed below a floor panel of the automobile and supplies electric power to the traveling motor; and

a vehicle-body side member to which vehicle rear sides of the lower-side impact absorption members are connected, wherein

a battery member extending in the vehicle width direction is provided at a vehicle front portion of the battery, and

the vehicle-body side member is connected to the battery member.

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

the upper-side cross member and the lower-side cross member extend further on the vehicle-width-direction outer side than the bumper reinforcement, and

vehicle front sides of the upper-side impact absorption members and the lower-side impact absorption members are positioned farther on the vehicle-width-direction outer side than the bumper reinforcement.

8. The vehicle-body front structure according to claim 1 , further comprising:

a traveling motor;

a battery that is disposed below a floor panel of the automobile and supplies electric power to the traveling motor; and

a vehicle-body side member to which vehicle rear sides of the lower-side impact absorption members are connected, wherein

a battery member extending in the vehicle width direction is provided at a vehicle front portion of the battery, and

the vehicle-body side member is connected to the battery member.

9. The vehicle-body front structure according to claim 2 , further comprising:

a traveling motor;

a battery that is disposed below a floor panel of the automobile and supplies electric power to the traveling motor; and

a vehicle-body side member to which vehicle rear sides of the lower-side impact absorption members are connected, wherein

a battery member extending in the vehicle width direction is provided at a vehicle front portion of the battery, and

the vehicle-body side member is connected to the battery member.

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

a traveling motor;

a battery that is disposed below a floor panel of the automobile and supplies electric power to the traveling motor; and

a vehicle-body side member to which vehicle rear sides of the lower-side impact absorption members are connected, wherein

a battery member extending in the vehicle width direction is provided at a vehicle front portion of the battery, and

the vehicle-body side member is connected to the battery member.

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

a traveling motor;

a battery that is disposed below a floor panel of the automobile and supplies electric power to the traveling motor; and

a vehicle-body side member to which vehicle rear sides of the lower-side impact absorption members are connected, wherein

a battery member extending in the vehicle width direction is provided at a vehicle front portion of the battery, and

the vehicle-body side member is connected to the battery member.
