Vehicle body structure
Provided is a vehicle body structure capable of preventing separation between a bumper beam and a bumper beam mounting member on the non-collision side at the time of an offset collision. The vehicle body structure includes a bumper beam, a pair of bumper beam mounting members, and a pair of holding members. The holding member includes an outer mounting portion for mounting an outer side in the vehicle width direction of the holding member on the bumper beam mounting member, and a front mounting portion for mounting an inner side in the vehicle width direction of the holding member on the front surface portion of the bumper beam. The front mounting portion extends to a position corresponding to a vehicle width direction inner end portion of the bumper beam mounting member in a front-rear direction at least on the front surface portion of the bumper beam.
1. A vehicle body structure comprising:
a bumper beam extending in a vehicle width direction;
a pair of left and right bumper beam mounting members provided outside in the vehicle width direction on a rear surface of the bumper beam and mounting the bumper beam on the vehicle body; and
a pair of left and right holding members provided on a front surface of the bumper beam and connecting the bumper beam and the bumper beam mounting member, wherein
the holding member comprises:
an outer mounting portion for mounting an outer side in the vehicle width direction of the holding member on the bumper beam mounting member; and
a front mounting portion for mounting an inner side in the vehicle width direction of the holding member on the front surface of the bumper beam,
the front mounting portion extends to a position corresponding to a vehicle width direction inner end portion of the bumper beam mounting member in a front-rear direction at least on the front surface of the bumper beam,
the holding member is disposed offset to one side in an up-down direction with respect to a center in the up-down direction of the bumper beam,
an inclined side inclined to be located on the inner side in the vehicle width direction as it goes from the one side in the up-down direction to the other side in the up-down direction is formed in a vehicle width direction inner end portion of the front mounting portion, and
an inclined welded portion for fixing the front mounting portion and the bumper beam is formed on the inclined side.
2. The vehicle body structure according to claim 1 , wherein
the bumper beam mounting member comprises:
a bumper beam extension provided on the rear surface of the bumper beam and extending in the front-rear direction; and
a mounting plate provided on a rear surface of the bumper beam extension and extending in the vehicle width direction, wherein
the mounting plate has a mounting flange positioned outside in the vehicle width direction of the bumper beam extension and the bumper beam, and
the outer mounting portion is fixed to the mounting flange in the front-rear direction.
3. The vehicle body structure according to claim 1 , wherein
the bumper beam comprises:
a linear portion extending in the vehicle width direction; and
a bent portion bent from a vehicle width direction outer end portion of the linear portion toward the bumper beam mounting member and located inside in the vehicle width direction of the vehicle width direction inner end portion of the bumper beam mounting member, and wherein
the front mounting portion extends to the bent portion.
4. The vehicle body structure according to claim 1 , wherein
the bumper beam has a folded portion formed by folding a vehicle width direction outer end portion of the bumper beam such that a front surface thereof is closer to a rear surface thereof as it goes to the outer side in the vehicle width direction, and
the front mounting portion is fixed to a position corresponding to the folded portion in the front-rear direction on a front surface of the bumper beam.
5. The vehicle body structure according to claim 2 , further comprising:
a pair of left and right side frames fixed to a rear surface of the mounting plate and extending in the front-rear direction;
a pair of left and right lower members fixed to the rear surface of the mounting plate and extending in the front-rear direction on the outer side in the vehicle width direction of the side frames; and
a gusset member for connecting the side frame and the lower member on the rear surface side of the mounting plate, wherein
the bumper beam extension is divided in a vehicle width direction into a first divided body located inside in the vehicle width direction and a second divided body located outside in the vehicle width direction,
the bumper beam extension has a connecting portion for connecting the first divided body and the second divided body, and
the gusset member is disposed at a position corresponding to the connecting portion in the front-rear direction.
6. The vehicle body structure according to claim 1 , wherein
the front mounting portion comprises:
an upper side; and
a lower side separated downward from the upper side,
first welded portions for fixing the front mounting portion and the bumper beam are respectively formed inside in the vehicle width direction of the upper side and the lower side, and
a welding length of the first welded portion of one of the upper side and the lower side is formed shorter than that of the first welded portion of the other of the upper side and the lower side.
7. The vehicle body structure according to claim 6 , wherein
second welded portions for fixing the front mounting portion and the bumper beam are respectively formed outside in the vehicle width direction of the upper side and the lower side, and
a welding length of the second welded portion of the other of the upper side and the lower side is formed shorter than that of the second welded portion of the one of the upper side and the lower side.
