[0021] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0022] like Figures 1 to 5 As shown, it is a schematic diagram of the structure of the 3D massage core provided by the present invention. The 3D massage core includes a base 10, a kneading component 20 rotatably arranged on the base 10, a knocking component 30 rotatably arranged on the kneading component, and a lifting component 40 rotatably arranged on the knocking component 30. The 3D massage core also includes some other functional modules, such as a controller and a distribution box for controlling the start and stop of each component, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0023] It should be noted that, since the kneading component 20 and the knocking component 30 are both axisymmetric structures with the central axis of the base 10 as the axis of symmetry, only the kneading component 20 and the knocking component 30 on one side are drawn in the drawings of the specification, and the other side is the same as the various functional modules shown in the figure and presents an axisymmetric structure, but they are not illustrated one by one in the figure.

[0024] The base 10 is a frame structure for carrying the above-mentioned functional modules. It adopts a hollow design and is provided with reinforcing ribs to ensure the stability of the structural strength while reducing the weight. A walking assembly 11 is provided on the base 10, so that the base 10 can be moved according to actual needs to change the massage position. A travel switch 12 is provided at both ends of the bottom of the base 10. The two travel switches 12 are respectively close to the two ends of the threaded rod 41 described below. When the following installation sleeve 45 moves to the two ends close to the threaded rod 41, the installation sleeve 45 will abut against the contact of the travel switch 12, so that the second motor 462 stops moving, avoiding the collision of the installation sleeve 45 with the base 10.

[0025] The kneading assembly 20 includes a kneading drive shaft 21 rotatably disposed on the base 10, two eccentric bearings 22 symmetrically sleeved on the kneading drive shaft 21, two kneading rods 23 rotatably mounted on the outside of each of the eccentric bearings 22, a group of kneading wheels 24 rotatably disposed at the end of each of the kneading rods 23, and a kneading motor 25 driving the kneading drive shaft 21 to rotate. It should be noted that the kneading principle and eccentric wheel structure of the kneading assembly 20 are both existing technologies widely used in the field of massage movement technology, such as a massage movement disclosed in the Chinese invention with application number CN202211616588.4, which has a detailed introduction to the relevant content, so it will not be repeated here.

[0026] The knocking assembly 30 includes a knocking drive motor 31 arranged in the following mounting sleeve 45, a knocking drive rod 32 transmission-connected to the knocking drive motor 31, first transmission arms 33 respectively rotationally arranged at both ends of the knocking drive rod 32, second transmission arms 34 respectively hinged at the end of each of the first transmission arms 33, and a spherical connector 35 respectively arranged between each of the second transmission arms 34 and the kneading rod 23.

[0027] The knocking drive motor 31 is arranged between the upper sleeve 451 and the lower sleeve 453 of the mounting sleeve 45, and the knocking drive rod 32 is also rotatably inserted between the upper sleeve 451 and the lower sleeve 453. The knocking drive motor 31 and the knocking drive rod 32 are connected to each other through a pulley structure. The two first transmission arms 33 are eccentrically arranged at the two ends of the knocking drive rod 32 respectively. The knocking drive motor 31 is a brushless motor with low noise and long service life.

[0028] The plane formed after the first transmission arm 33 rotates is perpendicular to the plane formed after the second transmission arm 34 rotates. An eccentric cam 36 is rotatably arranged between the first transmission arm 33 and the knocking drive rod 32. The second transmission arm 34 is arc-shaped. The first transmission arm 33 is composed of two clips 331 that are engaged on the knocking drive rod 32 to be rotatably connected with the knocking drive rod 32. The free end of the clip 331 extends toward the second transmission arm 34 and is hinged with the second transmission arm 34 so that the second transmission arm 34 can rotate relative to the first transmission arm 33. The two clips 331 are detachably connected by bolts to facilitate disassembly and assembly during maintenance.

[0029] The ball connector 35 is a ball head connection structure, including a ball arranged on the kneading rod 23, and a spherical groove arranged at the end of the second transmission arm 34. The ball is rotatably inserted in the spherical groove, so that the kneading rod 23 and the second transmission arm 34 can obtain a wider rotation angle when they are rotatably connected. This connection structure is an existing technology widely used in the industrial field and should be well known to those skilled in the art. Therefore, the corresponding structures are not illustrated one by one in the drawings of the specification, but only briefly described in the specification.

[0030] The knocking process of the knocking drive motor 31 is as follows: when the knocking drive rod 32 rotates, the first transmission arm 33 will reciprocately pull the second transmission arm 34 under the drive of the eccentric cam 36 , so that the second transmission arm 34 reciprocates and pulls the kneading rod 23 .

[0031] The lifting assembly 40 includes a threaded rod 41 horizontally arranged on the base 10, at least one guide rod 42 arranged on the base 10 and parallel to and spaced from the threaded rod 41, a screw sleeve 43 threadedly mounted on the threaded rod 41, a worm gear 44 fixedly mounted on the outside of the screw sleeve 43, a mounting sleeve 45 slidably mounted on the outside of the guide rod 42 and covering the outside of the screw sleeve 43, and a worm drive assembly 46 arranged on the mounting sleeve 45 and meshing with the worm gear.

[0032] The extension direction of the threaded rod 41 is perpendicular to the extension direction of the knocking drive rod 32. Both ends of the guide rod 42 are fixedly arranged on the base 10. In this embodiment, the number of the guide rods 42 is two, and the two guide rods 42 are symmetrically arranged on both sides of the threaded rod 41. The guide rod 42 is used to guide the installation sleeve 45 to move along the guide rod 42. In this embodiment, the guide rod 42 is located above the threaded rod 41, and can provide certain protection for the threaded rod 41 during use, so as to prevent the user from placing hard objects on the massage chair, and the hard objects are pressed against the surface of the threaded rod 41 to damage the threaded rod 41.

[0033] The screw sleeve 43 is cylindrical, and its inner wall is provided with threads. At least two lubrication grooves 431 are provided on the outside of the screw sleeve 43 along the axial direction, and a collar 432 is fixedly mounted on both ends of the screw sleeve 43. In this embodiment, the number of the lubrication grooves 431 is 4 and they are centrally symmetrically distributed along the axis. When in use, lubricating oil is filled in the lubrication grooves 431 to reduce the friction between the screw sleeve 43 and the collar 432, so that the screw sleeve 43 can rotate in the collar 432.

[0034] The worm wheel 44 is disposed in the middle of the screw sleeve 43. The worm wheel 44 is meshed with the worm drive assembly 46. The worm drive assembly 46 includes a worm 461 and a second motor 462 that drives the worm 461 to rotate. The second motor 462 is a brushless motor with low noise and long service life.

[0035] The mounting sleeve 45 includes an upper sleeve 451 slidably mounted on the outside of the two guide rods 42, a positioning sleeve 452 disposed at the bottom of the screw sleeve 43 and bolted to the upper sleeve 451, and a lower sleeve 453 disposed at the bottom of the upper sleeve 451 and covering the outside of the positioning sleeve 452.

[0036] The upper sleeve 451 is a frame structure, so as to reduce the weight of the mounting sleeve 45. Four collars 454 are symmetrically arranged on the top of the upper sleeve 451. Two collars 453 are respectively arranged on each guide rod 42, and the collars 454 are respectively close to the two ends of the upper sleeve 451, so as to ensure the stable connection between the upper sleeve 451 and the guide rod 42. The upper sleeve 451 and the lower sleeve 453 are detachably connected by bolts. A plurality of through grooves 455 extending along the hole axis direction are arranged on the inner hole wall of the collar 454. The through grooves 455 are respectively distributed symmetrically along the axis of the collar 454. The two ends of the through grooves 455 are connected to the atmosphere, and lubricating oil is filled in the through grooves 455 to reduce the wear between the mounting sleeve 45 and the guide rod 42.

[0037] The positioning sleeve 452 is provided with a receiving groove 456 for receiving the screw sleeve 43 and the worm wheel 44, and two positioning grooves 457 respectively arranged on both sides of the receiving groove 456 and used to receive the collar 453. When the screw sleeve 43 and the worm wheel 44 are placed in the receiving groove 456, the two ends of the screw sleeve 43 are respectively located at the positioning grooves 457. The collar 453 is rotatably arranged in the positioning grooves 457.

[0038] When in use, the worm 461 is driven by the second motor 462 to rotate, thereby driving the worm wheel 44 to rotate, and then the screw sleeve 43 rotates outside the threaded rod 41, that is, the screw sleeve 43 moves along the extension direction of the threaded rod 41. Since the mounting sleeve 45 is sleeved on the outside of the screw sleeve 43, when the screw sleeve 43 moves, the mounting sleeve 45 will also move accordingly. Because the knocking component 30 is hinged on the mounting sleeve 45, when the mounting sleeve 45 moves, the angle between the connecting line between the knocking component 30 and the mounting sleeve 45 and the extension line of the threaded rod 41 changes accordingly. Since the knocking component 30 is hinged to the massage component 20, the massage component 20 will produce synchronous displacement with the rotation and lifting or rotation and lowering of the knocking component 30.

[0039] Compared with the prior art, the 3D massage movement provided by the present invention is provided with the screw sleeve 43 and a worm wheel 44 outside the screw sleeve 43, the worm wheel 44 is connected to a worm drive assembly 46, and the screw sleeve 43 is driven to rotate by the rotation of the worm drive assembly 46, thereby driving the screw sleeve 43 to rotate along the threaded rod 41. Since the screw sleeve 43 and the threaded rod 41 are connected by a threaded rotation, and the screw sleeve 43 can withstand more force in the radial direction, it can effectively push the knocking assembly 30 and the kneading assembly 20 to enhance the massage intensity and increase the comfort of the user when using it.
