Principle of operation

The massage chair movement structure of the technical scheme can realize three different movement modes, thereby realizing three massage effects.

First movable mechanism 200 is started up, second movable mechanism 300 is active when standby

The first driving member 210 is activated to rotate the two output shafts 221 in opposite directions, and the pair of first eccentric members 222 drives the massage arm 100 to perform eccentric motion at a first point through the massage head 700b, and meanwhile, since the massage arm 100 is hinged at a second point and the second point is limited to be movable only in the x-y plane by the hinge, the massage arm 100 forms a single swing motion with a third point as a fixed point, as known by those skilled in the art, the third point is located between the second point and the first end 120, and the specific position is determined by the distance length between the first end 120 and the middle 130, the distance length between the middle 130 and the second end 140, the length of the short shaft 630, and the like. Meanwhile, the upper part of the massage arm 100 is mounted on the rotating shaft 321 through the second collar 323, and the second collar 323 and the second eccentric member 322 can rotate relatively, so that when the first driving member 210 works, the massage arm 100 moves up and down along the axis of the second collar 323. The motion of the massage arm 100 formed by the first moving mechanism 200 is a proper combination of the single pendulum motion and the up-down motion.

(II) the first moving mechanism 200 stands by and the second moving mechanism 300 moves when being started up

The second driving member 310 is activated, and the pair of second eccentric members 322 rotatably push and retract the massage arm 100, while being limited by the limiting action of the pair of limiting lugs 521 on the massage arm 100, so that the massage arm 100 can only perform a single swinging motion in the y-z plane with the first point as a fixed point.

(III) Activity of the first Activity mechanism 200 and the second Activity mechanism 300 being started at the same time

When the first moving mechanism 200 and the second moving mechanism 300 are simultaneously started, the massage arm 100 of the present embodiment is a sum of vectors formed by the working tracks when the two are independently operated.

Therefore, the massage chair movement structure of the technical proposal enables the massage heads 700a, b and c arranged on the massage arm 100 to simultaneously carry out beating and kneading actions, and the simulation reduction degree of the hand massage is higher.

The present embodiment is only for explanation of the present application and is not to be construed as limiting the present application, and modifications to the present embodiment, which may not creatively contribute to the present application as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present application.
