AI Technical Summary
Traditional massage chairs use a single motor-driven, single-rotation-axis structure with a fixed motion trajectory. This makes it impossible to simulate the alternating kneading and differentiated pressure massage techniques of a professional massage therapist. Furthermore, the massage area is limited and cannot be adjusted to different positions as needed.
It adopts a dual-mechanism massage mechanism, including a servo motor-driven moving plate and sliding block structure, combined with multiple cams and rotating wheels. The rotation speed and direction of the rotating shaft are independently controlled by the two drive motors to achieve multiple massage modes. It is also equipped with a cleaning brush to clean impurities in real time and avoid clogging.
It enables precise adjustment of the massage position, simulates the alternating kneading motion of both hands, increases the difference and layering of the massage area, reduces maintenance frequency, extends the life of the device, and improves the user experience.
