Constant-force springs are a special type of spring characterized by a nearly constant elastic force within a certain working range. They are widely used in many fields, including automotive, electronics, medical devices, and aerospace. The operating principle of a constant-force spring is based on Hooke’s law, which states that a spring’s elastic force is proportional to its extension or compression. However, unlike ordinary springs, the

At present, various types of constant-force spring hangers and supports designed and manufactured both in China and abroad use GB1239 cylindrical helical compression springs as the elastic energy-storage element. Because these springs have low stiffness and an ineffective power ratio as high as 65%, the resulting products are bulky and heavy, difficult to manufacture, and inconvenient to install during construction. This is especially true for
