Three-dimensional massage device of massage armchair

Abstract

Disclosed is a three-dimensional massage apparatus for a massage chair. The apparatus comprises a kneading massage apparatus, a pounding massage apparatus, a massage intensity adjustment apparatus and a travelling apparatus, wherein the massage intensity adjustment apparatus comprises front and rear extension / retraction frames (12), an intensity electrical motor (22) and a magnetic induction type magnetic transmission; the kneading massage apparatus and the pounding massage apparatus are installed on the front and rear extension / retraction frames (12), and by the intensity electrical motor (22) driving the rotation of a driving permanent magnet turntable (31) via a belt pulley and then the driving permanent magnet turntable (31) driving the rotation of a driven permanent magnet turntable (35), and by means of a seventh belt pulley (28) and an eighth belt pulley (39) driving the rotation of a gear wheel (41) arranged on a gear shaft (44), the front and rear extension / retraction frames (12) are pushed to move. Throughout the whole massage process, and with no detection of body shape being required, the massage intensity apparatus of the present invention can massage along the curves of the human body from beginning to end and the massage strength can be adjusted by the user at will, the trajectory of the massage can entirely coincide with the curves of the back of the human body, and close-fitting massage effects are genuinely achieved.

Description

technical field [0001] The invention relates to a three-dimensional (3D) massage device for a massage chair, especially a massage device that can automatically adapt to changes in the curve of the back of the human body for rubbing, tapping, and finger pressure massage, and the user can adjust the massage intensity according to needs.

AI Technical Summary

Problems solved by technology

The massage wheel can move up and down and left and right along the back of the human body, but the massage device cannot perform body-fitting massage according to the changes in the curve of the human back. A massage chair with a S-shaped track, that is, the massage device moves up and down along the S-shaped track, which improves the fit of the massage device to the human body. However, different users have different heights and different back curves, resulting in unsatisfactory massage effects.
