AI Technical Summary
Common massage mechanism components have multiple massage heads in fixed positions, making it impossible for them to work separately. This results in the distance between adjacent massage heads being fixed, failing to meet the special massage needs of some user groups and leading to poor massage effects.
The 4D massage mechanism adopts a design with the main shaft and the secondary shaft arranged in parallel. The massage components are driven by the walking drive and the rotation drive. The first and second drive units are combined to realize the independent reciprocating sliding of the first and second massage groups, allowing the spacing between the massage components to change and achieve a 4D motion effect.
It enables diverse movements of the massage components, meeting the specific massage needs of different users and improving the massage effect.

[0051] In this embodiment, the first drive unit 2 includes a first brushless DC motor 21, a first transmission screw 22, and a first pulley transmission structure 23. The first transmission screw 22 is rotatably mounted between the first rotating arm 60 and the second rotating arm 70 and is parallel to the guide rod 80.

[0054] The beneficial technical effects of the 4D massage mechanism in this application are roughly as follows:
[0055] The overall structure is compact and occupies little installation space. Activating the walking drive unit 40 can drive the main shaft 20 to rotate, which, together with the external walking mechanism, can drive the entire 4D massage mechanism to move in a straight line. Activating the rotation drive unit 50 can drive the secondary shaft 30 to rotate, which, together with the first gear 301 and the first arc tooth 601, and the second gear 302 and the second arc tooth 701, can drive the first massage group 1 and the second massage group 3 to rotate along the main shaft 20. Activating the first drive unit 2 can drive the first massage group 1 to slide independently back and forth along the guide rod 80, and activating the second drive unit 4 can drive the second massage group 3 to slide independently back and forth along the tapping axis 90, thus achieving a comprehensive 4D motion massage effect. At the same time, the first massage group 1 and the second massage group 3 are controlled and moved independently (i.e., they work separately). The distance between the first massage group 1 and the second massage group 3 can be changed as needed, which is sufficient to meet the special massage needs of some user groups, resulting in a better massage effect.
