Abstract

A vehicle bumper structure is provided with a functional component having a function other than an impact absorbing function, and an absorber is provided between a bumper cover and reinforcement. The absorber includes a first impact absorbing member that has a hole near the functional component, and a second impact absorbing member that is inserted into the hole and is more rigid than the first impact absorbing member. The second impact absorbing member may also have a protruding portion that protrudes outward on a side surface with respect to an insertion direction into the hole.

First claim

1 . A vehicle bumper structure comprising:
a functional component having a function other than an impact absorbing function; and an absorber provided between a bumper cover and a reinforcement, wherein the absorber includes a first impact absorbing member defining a hole near the functional component, and a second impact absorbing member being inserted into the hole, the second impact absorbing member being more rigid than the first impact absorbing member.

2 . The vehicle bumper structure according to claim 1 , wherein
the second impact absorbing member has a protruding portion protruding outward, the protruding portion provided on a side surface of the second impact absorbing member with respect to an insertion direction into the hole; and movement of the second impact absorbing member in a direction opposite the insertion direction is inhibited by the protruding portion biting into an inside wall of the hole in the first impact absorbing member.

3 . The vehicle bumper structure according to claim 2 , wherein
the protruding portion has an inclined portion and a vertical wall portion, the inclined portion being inclined toward a side surface of the second impact absorbing member, on an insertion direction side of an apex portion of the protruding portion, the vertical wall portion inhibiting the second impact absorbing member from moving in a direction opposite the insertion direction by catching on the inside wall of the hole on a side opposite the insertion direction of the apex portion.

4 . The vehicle bumper structure according to any one of claims 1 to 3 , wherein
with at least one of the bumper cover and the reinforcement as a counterpart member,, a member that suppresses contact noise between the second impact absorbing member and the counterpart member is provided on a portion of the second impact absorbing member, the portion of the second impact absorbing member facing the counterpart member.

5 . The vehicle bumper structure according to any one of claims 1 to 4 , wherein
the second impact absorbing member has an extended portion protruding outward from an edge portion of the second impact absorbing member on a side opposite an insertion direction, the extended portion provided on a side surface of the second impact absorbing member with respect to the insertion direction into the hole; and
movement of the second impact absorbing member in the insertion direction is inhibited by the extended portion catching on the first impact absorbing member.

6 . The vehicle bumper structure according to any one of claims 1 to 5 , wherein
the second impact absorbing member is wider on a reinforcement side than on a bumper, cover side in a cross-section in an insertion direction into the hole.

7 . A bumper absorber provided on a vehicle, comprising:
a first impact absorbing member defining a hole; and a second impact absorbing member being inserted into the hole, the second impact absorbing member being more rigid than the first impact absorbing member, wherein the second impact absorbing member has a protruding portion protruding outward, the protruding portion provided on a side surface of the second impact absorbing member with respect to an insertion direction into the hole; and movement of the second impact absorbing member in a direction opposite the insertion direction is inhibited by the protruding portion biting into an inside wall of the hole in the first impact absorbing member.
