Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Figures 1 to 8 A rotating massage footrest device according to an embodiment of the present invention includes...

[0042] The bracket 1 is equipped with a drive assembly 2, which drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the torsion assembly 4 to move. The bracket 1 is used to determine the relative position of the moving elements on it. Specifically, the bracket 1 includes a chassis 11 and a mounting seat 12 on the chassis 11. The drive shaft is disposed in the mounting seat 12, and the two ends of the mounting seat 12 abut against the drive shaft to restrict the movement of the drive shaft along the length direction.

[0043] The specific structure of the mounting base 12 can be as follows: The mounting base 12 has a cavity for fixing the bearing, one side is open for the insertion of the rotating shaft 3, and the other side is closed. The rotating shaft 3 is inserted into the inner hole of the bearing, and the bearing is fixedly placed in the cavity. Therefore, the rotating shaft 3 can rotate freely. At the same time, since the other end of the mounting base 12 is closed, the rotating shaft 3 will not slip off axially.

[0044] Optionally, the drive assembly 2 includes a worm motor 21 and a transmission gear 22. The worm motor 21 is fixed to the bracket 1, and the transmission gear 22 is connected to the drive shaft. The worm motor 21 provides low-speed, high-torque output, and the transmission gear 22 can further adjust the reduction ratio to adapt to massage needs and facilitate assembly and maintenance.

[0045] The drive shaft is provided with a cam 31, which has an angle with the drive shaft. A circumferential groove 32 is formed on the cam 31, and a slip ring 33 is fitted on the groove 32. The torsion assembly 4 is arranged around the slip ring 33. Specifically, the cam 31 includes a first wheel assembly 311 and a second wheel assembly 312. One end of the first wheel assembly 311 is provided with an enlarged end, which is partially recessed radially inward to form the bottom surface and one side wall of the groove 32. The end face of the second wheel assembly 312 forms the other side wall of the groove 32.

[0046] Cam 31 can drive the torsion swing assembly 4 to reciprocate radially along cam 31, while the slide groove 32 on cam 31, due to the angle between cam 31 and the drive shaft, causes the torsion swing assembly 4 to reciprocate axially along cam 31. The combination of the two-dimensional motion realizes the torsion swing motion in space. In order to prevent the torsion swing assembly 4 from displacing axially along the drive shaft during motion, a traction component is set to constrain it. The combination of cam 31, slide groove 32 and slip ring 33 also realizes mutual constraint, so that the torsion swing assembly 4 torsional within a limited area without slipping.

[0047] The torsion component 4 includes a traction element 41 and a torsion element 42. One end of the traction element 41 is hinged to the bracket 1, and the other end is hinged to the torsion element 42. The torsion element 42 is arranged around the slip ring 33 and connected to the external massage structure. Specifically, the traction element 41 includes a traction horizontal shaft 411 hinged to the bracket 1, a traction connector 412 sleeved on the traction horizontal shaft 411, and a traction rod 413 with one end hinged to the traction connector 412 and the other end hinged to the torsion element 42 via a ball joint. The traction rod 413 swings along the length direction of the traction horizontal shaft 411.

[0048] Optionally, the torsion element 42 includes a torsion structure 421, a first side plate 422 and a second side plate 423 respectively disposed on both sides of the torsion structure 421, and a transition plate 424; the traction element 41 is hinged to the torsion structure 421 by a ball joint, and the top surfaces of the first side plate 422 and the second side plate 423 form protrusions facing upward, which correspond to the mounting holes of the transition plate 424 to fix the transition plate 424.

[0049] During the movement of the torsion element 42, the traction element 41 is always subjected to forces in all directions in space. In order to make it only subject to axial forces, a universal joint is used at the connection between it and the torsion element 42.

[0050] The cam 31 rotates, causing the slip ring 33 to move up and down vertically along the rotation axis 3, and to swing back and forth along the rotation axis 3, thereby causing the torsion swing assembly 4 to move synchronously, and in turn causing the external massage structure to move in coordination.

[0051] A lower limb massager according to an embodiment of the present invention includes a calf massage device 200, a foot massage device 300, and an ankle twisting device. The ankle twisting device includes an upper housing 400 for fixing the foot and a rotating massage foot support device. The upper housing 400 fixes the foot, and the rotating massage foot support device moves to allow the foot to move relative to the calf. The specific structure of the rotating massage foot support device has been described above and will not be repeated here.
