Abstract
Official abstract text for this publication.
A shock absorbing member of the present disclosure is a shock absorbing member including a first hollow member (11) and a second hollow member (12) that are made of aluminum alloy and are weld joined to each other, in which a weld material and weld beads (W) do not project from a side on which a joined surface between the first hollow member (11) and the second hollow member (12) is located.
First claim
Opening claim text (preview).
The invention claimed is: 1. A shock absorbing member comprising: a first hollow member; and a second hollow member, wherein the first hollow member and the second hollow member are made of aluminum alloy and are joined to each other by a weld bead to form a joined surface that is used to receive shocks, the second hollow member has a step adjacent to the first hollow member that is receded from the joined surface, in a state before the joining of the first hollow member and the second hollow member, the step is open toward a front of the joined surface, a surface of an edge of an upper surface of the first hollow member and a surface of an edge of an under surface of the second hollow member are joined are each other in the step, and the weld bead does not project above the joined surface. 2. The shock absorbing member according to claim 1 , wherein the second hollow member has a triangular cross-section, and the first hollow member and the second hollow member have surfaces flush with each other on a crash surface side. 3. The shock absorbing member according to claim 1 , wherein at least one of the first hollow member or the second hollow member is formed of an extruded material. 4. The shock absorbing member according to claim 1 , wherein the first hollow member is a bumper reinforcement, the second hollow member is a raised member, and the shock absorbing member constitutes a bumper structure. 5. The shock absorbing member according to claim 2 , wherein at least one of the first hollow member or the second hollow member is formed of an extruded material. 6. The shock absorbing member according to claim 2 , wherein the first hollow member is a bumper reinforcement, the second hollow member is a raised member, and the shock absorbing member constitutes a bumper structure.
