[0063] like Figure 1 As shown, the present invention provides a massage movement, comprising:

[0064] Traveling mechanism 1, the traveling wheels 111 of the traveling mechanism 1 are arranged on both sides of the sheet metal frame 01;

[0065] The kneading mechanism 2 includes a first driving member 21, a rotating shaft 22, two eccentric sleeves 23 and two rocker arm assemblies 24; the two ends of the rotating shaft 22 are respectively arranged on the two side walls of the sheet metal frame 01; the two rocker arm assemblies 24 are respectively arranged on both sides of the rotating shaft 22, and each rocker arm assembly 24 is sleeved on the rotating shaft 22 through an eccentric sleeve 23; the first driving member 21 drives the rotating shaft 22 to rotate;

[0066] The finger pressure mechanism 3 includes two supports 31, two connecting rod shafts 32, two connecting rods 33, a screw 34, a screw nut moving seat 35 and a second driving member 36; the two supports 31 are arranged on the bottom plate of the sheet metal frame 01, and the two supports 31 are respectively at the two ends of the moving direction of the sheet metal frame 01; the two ends of the screw 34 are respectively arranged on the two supports 31; the screw nut moving seat 35 is slidably connected to the screw 34; the second driving member 36 drives the screw 34 to rotate; a connecting rod shaft 32 is respectively arranged on both sides of the screw nut moving seat 35, each connecting rod shaft 32 is connected to the rocker arm assembly 24 on the same side through a connecting rod 33, and the screw nut moving seat 35 moves through the connecting rod 33 to drive the rocker arm assembly 24 on the same side to move up and down.

[0067] The present invention provides a walking mechanism 1 to enable the sheet metal frame 01 to move on the massage chair, thereby adapting to massages of different heights and body parts; in addition, the present invention provides a kneading mechanism 2 to drive the rocker assembly to rock left and right when the shaft 22 rotates, so that the rocker assembly can knead the human body parts; in addition, the present invention provides a finger pressure mechanism 3 to drive the connecting rod 33 to move forward and backward through the movement of the screw nut moving seat 35, so that the connecting rod 33 pulls one end of the rocker assembly 24; at the same time, since the middle part of the rocker assembly 24 rotates around the shaft 22, when one end of the rocker assembly 24 (the end connected to the connecting rod 33) moves up and down, the other end of the rocker assembly 24 (the end with the massage head) moves up and down in the opposite direction, thereby achieving a pressing action on the muscles. In addition, as Figure 4 and Figure 6 As shown in the combination, when the screw nut moving seat 35 is in the initial position, the connecting rod 33 can keep the rocker arm assembly 24 flush with the bottom surface of the sheet metal frame 01, hide the rocker arm assembly 24 as much as possible, avoid the bulge of the massage chair in the non-massage state, and improve the comfort of the massage chair.

[0068] In order to enable the movement to move along the track of the massage chair to the part of the human body that needs massage; Figure 1 As shown, a walking mechanism 1 is provided, and the walking mechanism 1 includes two walking components 11, each of which is arranged on both sides of the walking direction of the sheet metal frame 01 (along the track direction of the massage chair); each walking component 11 includes a walking shaft 111, a walking wheel 112 and a walking drive 113; the two ends of the walking shaft 111 respectively pass through the two side walls of the sheet metal frame 01, and a walking wheel 112 is respectively provided at the two ends of the walking shaft 111, and the walking drive 113 drives the walking shaft 111 to rotate.

[0069] In order to match the setting of the track, the running wheel 112 can be a gear, and the track is a rack structure, thereby forming a gear rack structure.

[0070] In order to enable the traveling shaft 111 to rotate smoothly and avoid unnecessary wear on the sheet metal frame 01, a bearing 111a, a bearing stop ring 111b and a bearing end cover 111c are provided in the hole where the traveling shaft 111 and the side wall of the sheet metal frame 01 intersect, so that the traveling shaft 111 can rotate smoothly in the bearing 111a, and the bearing 111a is prevented from slipping out by the bearing stop ring 111b and the bearing end cover 111c.

[0071] In order to make the rocker arm assembly 24 more comfortable for the muscle massage; Figure 3As shown, a massage head 241 is provided at one end of the rocker arm assembly 24, and a rotation hole is provided at the other end of the rocker arm assembly 24. Specifically, the massage head 241 is a massage ball, and the massage ball can rotate freely, thereby massaging the muscles and avoiding contusion of the skin.

[0072] In order to be able to massage symmetrical positions of the body at the same time, preferably, the massage heads 241 are symmetrically arranged on the two rocker arm assemblies 24 along the longitudinal section of the sheet metal frame 01 (longitudinal direction, i.e., along the direction of the massage chair track).

[0073] If the rocker arm assembly 24 is directly fixed to the eccentric sleeve 23, when the rotating shaft 22 rotates, the rocker arm assembly 24 will rotate together, which may cause damage to the sheet metal frame 01; therefore, a bearing is set in the rotating hole of the rocker arm assembly 24, and the eccentric sleeve 23 is set in the bearing; when the rotating shaft 22 rotates, the eccentric sleeve 23 will reciprocate in the circumferential direction, thereby driving the rocker arm assembly 24 to reciprocate, forming a movement in which the two massage heads 241 will approach each other and then move away from each other, thereby achieving a kneading action on the muscles.

[0074] Since the middle part of the rocker arm assembly 24 is sleeved on the rotating shaft 22, according to the above description, the rocker arm assembly 24 will produce a swinging motion when the rotating shaft 22 rotates; at this time, if one end of the rocker arm assembly 24 is not fixed, it may cause the rocker arm assembly 24 to produce a rotational motion around the rotating shaft 22; therefore, a connecting rod 33 is set at one end of the rocker arm assembly 24 (the end facing away from the massage head 241), and at this time, the screw nut moving seat 35 actually plays a role in fixing the connecting rod 33, thereby fixing one end of the rocker arm assembly 24.

[0075] like Figure 7 As shown, when the screw nut moving seat 35 moves from the support 31 in the middle of the sheet metal frame 01 to the other support 31, the movement of the screw nut moving seat 35 drives one end of the rocker arm assembly 24 (the end facing away from the massage head 241) through the connecting rod 33, so that the end of the rocker arm assembly 24 is downward, and the other end of the rocker arm assembly 24 (the end with the massage head 241) is tilted. When the massage head 241 of the rocker arm assembly 24 is at the highest point, the angle between the rocker arm assembly 24 and the horizontal plane (the bottom surface of the sheet metal frame 01) is less than 90 degrees. The reason is that when the rocker arm assembly 24 turns over 90 degrees and then returns to the 0 degree position, the second driving member 36 needs to generate a large instantaneous power, which is not conducive to long-term use.

[0076] Similarly, if Figure 6As shown, when the screw nut moving seat 35 moves from the bracket 31 at one end of the sheet metal frame 01 to the support 31 in the middle, the movement of the screw nut moving seat 35 drives one end of the rocker assembly 24 (the end facing away from the massage head 241) through the connecting rod 33, so that the end of the rocker assembly 24 is upward, and the other end of the rocker assembly 24 (the end with the massage head 241) falls until it is flush with the horizontal plane. The above action enables the two massage heads 241 to move up and down, realizing the pressing action on the muscles.

[0077] In order to realize the rotation of the second driving member 36 driving the lead screw 34, the second driving member 36 is now set as a driving motor to drive the lead screw 34 fixedly connected with the bevel gear 361 to rotate, and the lead screw 34 drives the lead screw nut moving seat 35 installed thereon to make a linear motion.

[0078] Since the connecting rod 33 is a rigid structure, when the connecting rod 33 moves with the screw nut moving seat 35, the connecting rod 33 may break. To avoid this situation, the connecting rod 33 is now provided with a first connecting arm 331 and a second connecting arm 332. One end of the first connecting arm 331 is provided with a rotating hole 331a on which the connecting rod rotating shaft 32 is sleeved, and the other end of the first connecting arm 331 is rotatably connected to one end of the second connecting arm 332 by a pivot portion 331b. The axial direction of the rotating hole 331a is perpendicular to the axial direction of the pivot portion 331b. The second connecting arm 332 is a bent rod, so that the second connecting arm 332 can be as close to the rocker arm assembly 24 as possible from the end of the first connecting arm 331.

[0079] In order to enable the screw nut moving seat 35 to move and guide accurately between the two supports 31, two guide columns 311 are now set between the two supports 31, and the two guide columns 311 are located on both sides of the screw 34; each guide column 311 is slidably connected to a sliding rod sleeve 312 outside, and the sliding rod sleeve 312 is set on one side of the screw nut moving seat 35.

[0080] In order to facilitate the screw nut moving seat 35 to be arranged on the screw 34, and to facilitate the disassembly and assembly of the screw 34 and the guide column 311; Figure 5 As shown, the screw nut moving seat 35 now includes an upper seat 351 and a lower seat 352, and the upper seat 351 and the lower seat 352 are combined to form the screw nut moving seat 35; the screw 34 and the guide column 311 are located between the upper seat 351 and the lower seat 352.

[0081] Furthermore, in order to improve the friction resistance, a felt 313 is provided at the groove of the guide column 311 in the upper seat 351 and the lower seat 352 to assist the guide column 311 in sliding on the screw nut moving seat 35.

[0082] In order to adjust the rotation speed of the first driving member 21 output to the rotating shaft 22 , a speed reduction mechanism 211 is provided, and the first driving member 21 is connected to the rotating shaft 22 via the speed reduction mechanism 211 .

[0083] In order to accurately count the number of kneading times, a code disk 221 is now set at one end of the rotating shaft 22; at the same time, a corresponding optical coupling counter 222 is set on the side wall of the sheet metal frame 01; and the optical coupling counter 5 is connected to the controller of the massage chair; the rotating code disk 221 and the optical coupling counter 222 cooperate to count the number of rotations of the rotating shaft 22, and each rotation of the rotating shaft 22 realizes one kneading of the muscles.

[0084] In order to determine the specific position of the sheet metal frame 01 on the massage chair, a detection component 4 is now provided on the sheet metal frame 01, and the detection component can cooperate with the up and down travel switches and related position sensors set on the massage chair track; so that the controller can determine that the controlled sheet metal frame 01 moves to the corresponding position, and the controller then issues instructions to command the massage movement to perform the required kneading and pressing actions.

[0085] In order to detect the pressing force, a rocker arm detection component 5 is now set on the sheet metal frame 01, specifically under the rocker arm component 24, so as to determine the lifting height of the rocker arm component 24, thereby correspondingly changing the angle between the rocker arm component 24 and the horizontal plane, changing the lifting height of the massage head 241 and thus changing the pressing force, adjusting it to the pressing force required by the user, and improving the comfort of the massage; in addition, the pressing force of the massage head 241 can also be directly adjusted according to the bending shape of the human body to fully relax the human muscles and achieve precise massage of the muscles.

[0086] In summary, the present invention can realize movement on the massage chair by setting the walking mechanism 1, so as to massage the muscles of various parts of the back; in addition, the present invention can realize muscle kneading by setting the kneading mechanism 2, and the rocker arm assembly 24 can be raised and lowered by the finger pressure mechanism 3, so that the rocker arm assembly 24 is lowered in the non-massage state, and the rocker arm assembly 24 is hidden in the sheet metal frame 01, so as to improve the comfort of the massage chair. In addition, the kneading action of the present invention is realized by setting the eccentric sleeve 23 on the rotating shaft 22, so that the eccentric sleeve 23 is deflected by the rotation of the rotating shaft 22, and the swing arm assembly 24 is deflected. Compared with the prior art, the structure is simple and the setting cost is reduced.

[0087] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0088] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
