[0002] With the acceleration of the life rhythm, massage chairs, as household devices for relieving fatigue, have received extensive attention. Most of the leg and foot massage mechanisms of traditional massage chairs adopt fixed structures, and there are the following deficiencies:

[0003] 1. Poor adjustability: The height of the leg massage component is fixed, and it cannot adapt to the leg length differences of different users, resulting in limited massage range.

[0004] 2. Single function: Foot massage mostly relies on simple rotating rollers, lacking multi-dimensional swinging functions, and it is difficult to effectively stimulate the acupoints on the soles of the feet and move the ankle joints.

[0005] 3. Complex structure: Most of the existing drive components adopt split motor control, with low transmission efficiency, large occupied space, and high maintenance costs.

[0006] 4. Insufficient comfort: The movement trajectory of the leg kneading mechanism is single, prone to mechanical pressure, and the user experience is not good.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-9 , the present invention provides a technical solution: a separable leg and foot massage mechanism for a massage chair, including: a base plate 1 and a vertical fixed bracket 6. The base plate 1 and the vertical fixed bracket 6 are fixedly connected in an L shape. The foot massage assembly 5 is swingably installed on the base plate 1. The vertical fixed bracket 6 is slidably connected to the lifting bracket 2, and the lifting bracket 2 is connected to the lifting drive assembly 3. The leg massage assembly 4 is installed in front of the lifting bracket 2. The vertical fixed bracket 6 is assembled with the massage chair. The legs are placed in the leg massage assembly 4, and the feet are placed on the foot massage assembly 5 to realize the massage functions of the legs and feet, and at the same time realize the separation of the legs.

[0036] Specifically, the leg massage assembly 4 includes a leg side rubbing plate 41, a first drive motor 42, a first reduction gear set 43, a first transmission shaft 44 and an eccentric wheel 45. Among them, the first drive motor 42 is fixedly installed on the lifting bracket 2. The first drive motor 42 is drivingly connected to the first reduction gear set 43. The first reduction gear set 43 is drivingly connected to the first transmission shaft 44. Both ends of the first transmission shaft 44 are rotatably connected to the lifting bracket 2. Two eccentric wheels 45 are symmetrically and fixedly installed on the first transmission shaft 44. The leg side rubbing plate 41 includes a ring sleeve 411. The ring sleeve 411 is axially fixedly sleeved on the eccentric wheel 45. An arc-shaped limit hole 412 is opened at the lower end of the leg side rubbing plate 41. A limit pin rod 413 is slidably connected in the arc-shaped limit hole 412. The limit pin rod 413 is fixedly installed on the lifting bracket 2;

[0037] The first drive motor 42 outputs power, drives the first transmission shaft 44 to rotate through the first reduction gear set 43, and then drives the eccentric wheel 45 to rotate eccentrically, driving the upper circumference of the leg side rubbing plate 41 to move. Using the cooperation of the limit pin rod 413 and the arc-shaped limit hole 412, the leg side rubbing plate 41 is mechanically driven to rub the leg.

[0038] A vertical limit slide rail 11 is fixedly arranged on the upper surface of the base plate 1. The foot massage component 5 includes a foot support plate 51. The foot support plate 51 is made of plastic material, which can reduce the weight. A convex shaft 511 is integrally provided on the lower surface of the foot support plate 51. The convex shaft 511 is slidably connected to the vertical limit slide rail 11 up and down. A swing component 52 is installed between the base plate 1 and the foot support plate 51. Using the sliding connection of the convex shaft 511 and the vertical limit slide rail 11, the swing component 52 enables the foot support plate 51 to swing in multiple dimensions relative to the base plate 1.

[0039] Specifically, a second drive motor 55 is installed inside the foot support plate 51. The second drive motor 55 is a two-way output motor. One of the output ends is drivingly connected to a third reduction gear set 56, and the third reduction gear set 56 is drivingly connected to the swing component 52;

[0040] The swing component 52 includes an inclined surface wheel 521. The lower surface of the inclined surface wheel 521 is inclined, and a gasket 57 is movably laminated on the lower surface. The gasket 57 is fixedly installed on the upper surface of the base plate 1. The inclined surface wheel 521 is axially fixedly connected to a central shaft 523.

A limit bolt 524 is installed between the bottom of the inclined surface wheel 521 and the base plate 1, and the limit bolt 524 rotates following the inclined surface wheel 521;

[0041] By the second drive motor 55 outputting power, then driving the central shaft 523 to rotate through the third reduction gear set 56, the central shaft 523 drives the inclined surface wheel 521 to rotate. Due to the inclined design of the lower end surface of the inclined surface wheel 521, the central shaft 523 swings in a gyroscopic manner, and then drives the foot support plate 51 to swing, which can assist in moving the ankle joint.

[0042] A second reduction gear set 53 is also installed on the foot support plate 51. The other output end of the second drive motor 55 is drivingly connected to the second reduction gear set 53;

[0043] A sole massage roller assembly 54 is rotatably arranged on the foot support plate 51. The second reduction gear set 53 is drivingly connected to the sole massage roller assembly 54;

[0044] Specifically, the sole massage roller assembly 54 includes a heel massage roller 541, an arch massage roller 542, and a ball-of-foot massage roller 543, and a pulley drive assembly 544 is connected between two adjacent massage rollers;

[0045] The second reduction gear set 53 drives the ball-of-foot massage roller 543 to rotate through a rotating shaft and a pulley. The ball-of-foot massage roller 543 drives the arch massage roller 542 through the pulley drive assembly 544, and the arch massage roller 542 drives the heel massage roller 541 to rotate through the pulley drive assembly 544, so as to realize the stimulating massage of the sole of the foot.

[0046] Working principle: The first drive motor 42 outputs power, drives the first transmission shaft 44 to rotate through the first reduction gear set 43, and then drives the eccentric wheel 45 to rotate eccentrically, driving the upper circumference of the leg side rubbing plate 41 to move. By using the cooperation of the limit pin rod 413 and the arc-shaped limit hole 412, the leg side rubbing plate 41 rubs the leg. At the same time, the lifting drive assembly 3 reciprocally drives the lifting bracket 2 to lift, expanding the rubbing range of the leg side rubbing plate 41 on the leg;

[0047] The second drive motor 55 outputs power, and then drives the central shaft 523 to rotate through the third reduction gear set 56. The central shaft 523 drives the bevel wheel 521 to rotate. Due to the inclined design of the lower end surface of the bevel wheel 521, the central shaft 523 swings in a gyroscopic manner, and then drives the foot support plate 51 to swing, which can assist in moving the ankle joint;

[0048] The second reduction gear set 53 drives the ball-of-foot massage roller 543 to rotate through a rotating shaft and a pulley. The ball-of-foot massage roller 543 drives the arch massage roller 542 through the pulley drive assembly 544, and the arch massage roller 542 drives the heel massage roller 541 to rotate through the pulley drive assembly 544, so as to realize the stimulating massage of the sole of the foot.
