AI Technical Summary
Existing multi-functional massage chairs use an independent drive structure for their leg massage components, resulting in complex structures, high costs, difficulty in control, and a tendency for the left and right legs to move asynchronously.
The massage chair adopts a single-drive source dual-leg linkage mechanism, which achieves synchronous movement of the left and right legs through the combination of linkage transmission mechanism, pulley group and steel wire rope, simplifying the drive structure and reducing control complexity.
It achieves synchronized movement of the left and right legs of the massage chair, reducing hardware costs and control difficulty, and improving operational stability and user experience.
