AI Technical Summary

Technical Problem

The massage heads of existing massage chairs cannot move laterally, resulting in incomplete massage coverage and limited comfort.

Method used

Design a massage backrest that can move laterally. It adopts a track frame, a mechanism, a rotating massage head and a walking mechanism. The active wheel and the driven wheel are driven by a long-shaft brushless motor. Combined with the swing frame and linkage structure, it realizes the lateral reciprocating movement and up-down reciprocating movement of the rotating massage head. It works with electric heating elements and a vibration motor to perform massage.

Benefits of technology

It provides full-coverage back massage, improving massage comfort and coverage, and enhances the massage effect by combining heat therapy and vibration functions.
