Abstract

A vehicle front structure that reduces a shock load applied to immediately under a front grille by using a bumper beam as a support. A vehicle front structure includes a shock absorbing member at an interior of a bumper face on the side near an upper portion thereof which absorbs a load from the diagonally upper front side. The shock absorbing member is at the interior of the bumper face below a front grille, and includes a load receiving portion that receives a load, a locking portion locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at the time of receding of the shock absorbing member, and a connecting portion connecting the load receiving portion and the locking portion. A deformation facilitating portion with respect to a load from the upper front side is thus configured at the connecting portion.

Claims (31)

1. A vehicle front structure comprising:

a shock absorbing member at an interior of a bumper face on a side near an upper portion of the bumper face, the shock absorbing member being configured to absorb a load from a diagonally upper front side, the shock absorbing member being disposed at the interior of the bumper face below a front grille,

the shock absorbing member comprising:

a load receiving portion configured to receive a load;

a locking portion configured to be locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at a time of receding of the shock absorbing member; and

a connecting portion connecting the load receiving portion and the locking portion, wherein a deformation facilitating portion with respect to a load from an upper front side is configured at the connecting portion;

wherein a concave-convex shaped portion which is concave and convex in a vehicle width direction is configured at the load receiving portion.

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

the deformation facilitating portion is configured by a plurality of bent portions spaced apart from each other in a front-rear direction in a middle of the connecting portion.

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

a concave-convex shaped portion which is astride the bent portions in the front-rear direction and concave and convex in the vehicle width direction is configured at the connecting portion.

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

the load receiving portion includes a raised wall face, and the concave-convex shaped portion is configured in the vehicle width direction by a recess and a projection alternatively configured at the raised wall face in the vehicle width direction, and

the projection is flush with a front face portion of the raised wall face, and the recess is recessed rearward with respect to the raised wall face.

5. The vehicle front structure according to claim 3 , wherein

a separating portion is configured at a vehicle-width-direction center of the connecting portion, a mounting piece portion extending downward from the connecting portion via the separating portion is configured, and the concave-convex shaped portion is configured at the connecting portion adjacent to the separating portion.

6. The vehicle front structure according to claim 2 , wherein

the load receiving portion includes a raised wall face, and the concave-convex shaped portion is configured in the vehicle width direction by a recess and a projection alternatively configured at the raised wall face in the vehicle width direction, and

the projection is flush with a front face portion of the raised wall face, and the recess is recessed rearward with respect to the raised wall face.

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

the load receiving portion includes a raised wall face, and the concave-convex shaped portion is configured in the vehicle width direction by a recess and a projection alternatively configured at the raised wall face in the vehicle width direction, and

the projection is flush with a front face portion of the raised wall face, and the recess is recessed rearward with respect to the raised wall face.

8. A vehicle front structure comprising:

a shock absorbing member at an interior of a bumper face on a side near an upper portion of the bumper face, the shock absorbing member being configured to absorb a load from a diagonally upper front side, the shock absorbing member being disposed at the interior of the bumper face below a front grille,

the shock absorbing member comprising:

a load receiving portion configured to receive a load;

a locking portion configured to be locked to an upper end edge of a bumper beam located behind and below the load receiving portion at a time of receding of the shock absorbing member together with the locking portion; and

a connecting portion connecting the load receiving portion and the locking portion;

wherein

a deformation facilitating portion with respect to a load from an upper front side is configured at the connecting portion; and

the load receiving portion, the locking portion, and the connecting portion extend in a vehicle width direction between left and right side mounting piece portions and a center of the shock absorbing member.
