Massage armchair, and massage mechanism and massage method thereof

A massage mechanism, comprising a connecting seat, and two supporting seat assemblies respectively mounted on left and right sides of the connecting seat, two upper massage arms, and two lower massage arms, one of the upper massage arms and one of the lower massage arms are mounted on each supporting seat assembly, the massage mechanism further comprising:

• connecting shafts, each connecting shaft being movable on a respective one of the supporting seat assemblies, wherein a bottom end of each upper massage arm is rotatably connected to the connecting shaft, a bottom end of each lower massage arm is rotatably connected to the connecting shaft;
• first connecting members, wherein an upper end of each first connecting member is sleeved on a respective one of the connecting shafts;
• a kneading shaft, mounted on the connecting seat and connected to the two supporting seat assemblies on the left and right sides of the connecting seat, wherein the kneading shaft is connected to the first connecting members, a rotation axis of the kneading shaft and each supporting seat assembly form a first inclined angle, and the rotation axis of the kneading shaft and each first connecting member form a second inclined angle, the first inclined angle and the second inclined angle are equal in value;
• and
• a first driving assembly, configured to drive the kneading shaft to rotate so as to drive the first connecting members and the connecting shafts to reciprocate up and down on each supporting seat assembly, so that the upper massage arm rotates relative to each supporting seat assembly with an axis that perpendicularly passes through each supporting seat assembly as a rotation axis, and the lower massage arm rotates relative to each supporting seat assembly with the axis that perpendicularly passes through each supporting seat assembly as the rotation axis, so that an upper massage rolling wheel on each upper massage arm and a lower massage rolling wheel on each lower massage arm move close to or away from each other to realize a shoulder-clamping action;
• the two upper massage arms and the upper massage rolling wheels on the two supporting seat assemblies are simultaneously driven to move close to or away from each other, and the two lower massage arms and the lower massage rolling wheels on the two supporting seat assemblies are driven to move close to or away from each other to realize a kneading action.
