Abstract

The vehicle body front portion structure includes a pair of framework members, a bumper framework portion and spacer members. The framework members are long in a vehicle front-and-rear direction and are arranged side by side in a vehicle width direction. Front end sides of the framework members are energy-absorbing portions. The bumper framework portion is long in the vehicle width direction and spans between the front ends of the pair of framework members. The bumper framework portion includes protruding portion that protrudes to vehicle width direction outer sides relative to the framework members. Each spacer member includes a first portion extending from a front end portion and a second portion curving inward in the vehicle width direction from the first portion.

First claim

The invention claimed is:

1. A vehicle body front portion structure comprising:
a pair of framework members that are long in a vehicle front-and-rear direction and arranged side by side in a vehicle width direction, vehicle front-and-rear direction front end sides of the framework members being energy-absorbing portions;
a bumper framework portion that is long in the vehicle width direction and spans between the vehicle front-and-rear direction front ends of the pair of framework members, the bumper framework portion including a protruding portion that protrudes to a vehicle width direction outer side relative to the framework members;
a spacer member,
a vehicle front-and-rear direction front end side of which is fixed to the protruding portion,
a vehicle front-and-rear direction rear end side of which is a slide plate which opposes a wall portion of the framework member that is oriented to the vehicle width direction outer side and which is spaced apart from the wall portion by a gap,
a shape in plan view of a vehicle front-and-rear direction rear end portion of which is formed in an acute angle shape, and
a vehicle width direction dimension of which steadily decreases to rearward in the vehicle front-and-rear direction; and
a rear stopper that limits relative displacement of the spacer member, relative to the framework member, to the rearward in the vehicle front-and-rear direction beyond an energy absorption stroke according to the energy-absorbing portion.

2. The vehicle body front portion structure according to claim 1 , wherein a vehicle width direction dimension of the rear stopper is greater than a vehicle width direction dimension of the vehicle front-and-rear direction rear end of the spacer member.

3. The vehicle body front portion structure according to claim 2 , further comprising a side stopper that extends forward in the vehicle front-and-rear direction from a vehicle width direction outer end side of the rear stopper, and that limits relative displacement of a vehicle front-and-rear direction rear end portion of the second portion of the spacer member to the vehicle width direction outer side.

4. The vehicle body front portion structure according to claim 1 , wherein the rear stopper includes a guide shape that guides the vehicle front-and-rear direction rear end portion of the spacer member toward the side thereof at which the framework member is disposed.

5. The vehicle body front portion structure according to claim 1 , wherein the rear stopper protrudes outward in the vehicle width direction from a vehicle front-and-rear direction front end of a base portion that is fixed to the wall portion of the framework member, and the rear stopper is supported by a connecting wall that connects the rear stopper with the base portion.

6. A vehicle body front portion structure comprising:
a pair of framework members that are long in a vehicle front-and-rear direction and arranged side by side in a vehicle width direction, vehicle front-and-rear direction front end sides of the framework members being energy-absorbing portions;
a bumper framework portion that is long in the vehicle width direction and spans between vehicle front-and-rear direction front ends of the pair of framework members, the bumper framework portion including a protruding portion that protrudes to a vehicle width direction outer side relative to the framework members;
a spacer member including
a first portion, a vehicle front-and-rear direction front end portion of which is fixed to the protruding portion, the first portion extending from the vehicle front-and-rear direction front end portion toward the framework member in the vehicle front-and-rear direction and the vehicle width direction in a plan view, and
a second portion that curves inward in the vehicle width direction from the first portion, a slide plate which is formed in a vehicle width direction inner end portion of the second portion opposing a wall portion of the framework member that is oriented to the vehicle width direction outer side and being spaced apart from the wall portion by a gap, and a vehicle front-and-rear direction rear end portion of the second portion of the spacer member is formed in an acute angle shape in plan view, a vehicle width direction dimension of which steadily decreases to rearward in the vehicle front-and-rear direction; and
a rear stopper that limits relative displacement of the spacer member, relative to the framework member, to the rearward in the vehicle front-and-rear direction beyond an energy absorption stroke according to the energy-absorbing portion.

7. The vehicle body front portion structure according to claim 6 , wherein a vehicle width direction dimension of the rear stopper is greater than a vehicle width direction dimension of the vehicle front-and-rear direction rear end of the spacer member.

8. The vehicle body front portion structure according to claim 7 , further comprising a side stopper that extends forward in the vehicle front-and-rear direction from a vehicle width direction outer end side of the rear stopper, and that limits relative displacement of a vehicle front-and-rear direction rear end portion of the second portion of the spacer member to the vehicle width direction outer side.

9. The vehicle body front portion structure according to claim 6 , wherein the rear stopper includes a guide shape that guides the vehicle front-and-rear direction rear end portion of the spacer member toward the side thereof at which the framework member is disposed.

10. The vehicle body front portion structure according to claim 6 , wherein the rear stopper protrudes outward in the vehicle width direction from a vehicle front-and-rear direction front end of a base portion that is fixed to the wall portion of the framework member, and the rear stopper is supported by a connecting wall that connects the rear stopper with the base portion.
