Shape memory alloy wire attachment structures for a suspension assembly

A suspension assembly, comprising:

• a support member including a metal base layer, wherein the metal base layer includes a first attachment structure;
• a moving member movably coupled to the support member, the moving member including a plate, wherein the plate includes a second attachment structure, the second attachment structure including:
• a first portion including first elongate features being spaced apart by first spaces;
• and
• a second portion configured to be crimped together with the first portion, the second portion including second elongate features being spaced apart by second spaces, wherein the first spaces substantially align with the second features and the first features substantially align with the second spaces;
• and
• a shape-memory alloy wire being coupled to the first attachment structure and the first and second portions.

A suspension assembly, comprising:

• a support member including a metal base layer, wherein the base layer includes a first attachment structure;
• a moving member movably coupled to the support member, the moving member including a plate, wherein the plate includes a second attachment structure, the second attachment structure including:
• a first portion;
• and
• a second portion configured to be crimped together with the first portion, wherein at least one of the first and second portions includes at least one etched recess;
• and
• a shape-memory alloy wire coupled to the first attachment structure and the first and second portions.

A suspension assembly, comprising:

• a support member including:
• a metal base layer, wherein the base layer includes a first attachment structure, the first attachment structure including:
• a first portion including a recess, a platform and a first edge between the recess and platform;
• and
• a second portion configured to be crimped together with the first portion, the second portion including a second edge that is offset from the first edge, the first and second edges forming a cutting edge when the first and second portions are crimped together;
• a moving member movably coupled to the support member, the moving member including a plate, wherein the plate includes a second attachment structure;
• and
• a shape-memory alloy wire being coupled to the second structure and the first and second portions.
