The upper end of the first drive arm 33 is rotatably connected to the middle of the second drive arm 34. The end of the second drive arm 34 is rotatably connected to the massage chair main body bracket 1. The front end of the second drive arm 34 is rotatably installed with a first roller 35. The first roller 35 slides in contact with the fixed slide plate 27 on the back of the leg massage structure 2.

[0041] The servo linear electric push module drives the linear slider 36 to slide linearly, causing the lower end of the first drive arm 33 to slide linearly, and then the second drive arm 34 to rotate up and down with its end as the center of the circle, driving the first roller 35 to push the fixed slide plate 27 to rotate up and down. Since the upper end of the leg massage structure 2 is rotatably connected to the massage chair main body bracket 1, the fixed slide plate 27 drives the entire leg massage structure 2 to rotate up and down when it is pushed, which is used to assist in stretching the legs and improve the massage effect.

[0042] The servo linear electric push module includes a servo linear electric push module motor 31 and a servo linear electric push module slide 32. The servo linear electric push module motor 31 is provided with a reduction transmission mechanism, which drives and connects the screw structure, and the screw structure is connected to the linear slider 36. The linear slider 36 is directionally slidably connected to the servo linear electric push module slide 32. The reduction transmission mechanism is driven by the servo linear electric push module motor 31, and then the screw mechanism is driven to make the linear slider 36 move linearly along the servo linear electric push module slide 32.

[0044] The end of the second driving arm 34 is rotatably connected to the second hinged connection bracket 341, and the second hinged connection bracket 341 is fixedly connected to the massage chair main body bracket 1, so that when the second driving arm 34 is subjected to force, it rotates up and down with the second hinged connection bracket 341 as the center of the circle.

[0045] Working principle: Two independent first lifting drive components 3 are used to respectively drive the two leg massage structures 2 to rotate and lift relative to the massage chair main frame 1, thereby assisting in stretching the human legs and improving the massage effect.

[0047] See also Figure 7-10The present invention provides a technical solution: a massage chair with a separated leg and foot cross lifting and telescopic structure, comprising: a massage chair main body bracket 1 and a leg massage structure 2. The difference between this embodiment and the first embodiment is that a second lifting drive component 4 is provided between the massage chair main body bracket 1 and the leg massage structure 2, which is used to drive the leg massage structure 2 to rotate and lift relative to the massage chair main body bracket 1.

The second roller 45 rolls and fits the fixed slide 27 connected to the leg massage structure 2.

[0049] The servo motor reducer 41 drives the rotary drive arm 42 to rotate, pulling one end of the transmission connecting arm 43 to move in a circular motion, thereby causing the transmission connecting arm 43 to push and pull the lifting drive arm 44 to rotate up and down with its end as the center of the circle, so that the front end of the lifting drive arm 44 drives the second roller 45 to move in an arc up and down to push the fixed slide 27, so that the leg massage structure 2 is lifted up and down in a rotational manner to assist in stretching the legs.

[0050] The massage chair main frame 1 includes a top fixed beam 13 , on the surface of which a fixed bracket 46 is fixedly mounted. The fixed bracket 46 is rotatably connected to the leg massage structure 2 , so that the leg massage structure 2 rotates up and down with the fixed bracket 46 as the center.

[0051] The massage chair main body bracket 1 also includes a bottom fixed beam 12, on which a servo motor reducer 41 is fixedly installed. The servo motor reducer 41 is provided with an output shaft 411, which is fixedly connected to one end of a rotating drive arm 42. The servo motor reducer 41 drives the output shaft 411 to rotate, thereby driving the rotating drive arm 42 to rotate.

[0052] The end of the lifting drive arm 44 is rotatably connected to the third hinged connection bracket 441, and the third hinged connection bracket 441 is fixedly connected to the top fixed beam 13. When the lifting drive arm 44 is subjected to force, it rotates up and down with the third hinged connection bracket 441 as the center of the circle.

[0053] Working principle: Two independent second lifting drive components 4 are used to respectively drive the two leg massage structures 2 to rotate and lift relative to the massage chair main frame 1, thereby assisting in stretching the human legs and improving the massage effect.

[0054] Example 3

[0056] Specifically, the leg massage assembly 24 includes a leg side rubbing plate 241, a first drive motor 242, a first reduction gear set 243, a first transmission shaft 244 and an eccentric wheel 245, wherein the first drive motor 242 is fixedly mounted on the lifting bracket 22, the first drive motor 242 drives the first reduction gear set 243, the first reduction gear set 243 drives the first transmission shaft 244, both ends of the first transmission shaft 244 are rotatably connected to the lifting bracket 22, two eccentric wheels 245 are symmetrically fixedly mounted on the first transmission shaft 244, the leg side rubbing plate 241 includes a ring sleeve 2411, the ring sleeve 2411 is axially fixedly sleeved on the eccentric wheel 245, an arc-shaped limiting hole 2412 is opened at the lower end of the leg side rubbing plate 241, a limiting pin rod 2413 is slidably connected in the arc-shaped limiting hole 2412, and the limiting pin rod 2413 is fixedly mounted on the lifting bracket 22;

[0057] The first driving motor 242 outputs power, which drives the first transmission shaft 244 to rotate through the first reduction gear set 243, and then drives the eccentric wheel 245 to rotate eccentrically, driving the upper part of the leg side kneading plate 241 to move in a circular motion. The cooperation of the limiting pin rod 2413 and the arc-shaped limiting hole 2412 is used to realize the mechanical drive of the leg side kneading plate 241 to knead the legs.

[0058] A vertical limiting slide rail 211 is fixedly provided on the upper surface of the base plate 21. The foot massage component 25 includes a foot support plate 251. The foot support plate 251 is made of plastic material to reduce weight. A convex shaft 2511 is integrally provided on the lower surface of the foot support plate 251. The convex shaft 2511 is connected to the vertical limiting slide rail 211 for sliding up and down. A swing component 252 is installed between the base plate 21 and the foot support plate 251. Utilizing the sliding connection between the convex shaft 2511 and the vertical limiting slide rail 211, the swing component 252 causes the foot support plate 251 to swing in multiple dimensions relative to the base plate 21.

[0059] Specifically, a second drive motor 255 is installed in the foot support plate 251. The second drive motor 255 is a bidirectional output motor, one of the output ends of which is driven and connected to the third reduction gear set 256. The third reduction gear set 256 is driven and connected to the swing assembly 252.

The leg side kneading plate 241 kneads the legs by means of the cooperation between the limit pin 2413 and the arc-shaped limit hole 2412. At the same time, the lifting drive assembly 23 reciprocates to drive the lifting bracket 22 to rise and fall, thereby expanding the kneading range of the leg side kneading plate 241 on the legs.

[0067] The power is outputted by the second drive motor 255, and then driven to rotate by the third reduction gear set 256, and the central shaft 2523 drives the bevel wheel 2521 to rotate.
