[0036] Referring to Figures 1-4 , the utility model discloses a massage machine core, and the massage machine core can be slidably arranged on a back shell, and the massage machine core comprises:

[0037] A mounting shell 1 is provided with a walking mechanism 3, two groups of massage assemblies 2, a kneading mechanism 4 and a knocking mechanism 5 on the mounting shell 1.

[0038] The walking mechanism 3 is used for driving the mounting shell 1 to slide on the back shell, and comprises a first motor 31 and a first transmission assembly, and the first transmission assembly is in transmission connection with the first motor 31.

[0039] The kneading mechanism 4 is used for driving the two groups of massage assemblies 2 to rotate to perform kneading massage actions, and comprises a second motor 41 and a second transmission assembly, and the second motor 41 is in transmission connection with the second transmission assembly, and the second transmission assembly can drive the two groups of massage assemblies 2 to realize reciprocating clamping and kneading and partial swing.

[0040] The knocking mechanism 5 is used for driving the two ends of the two groups of massage assemblies 2 to alternately lift up to perform knocking massage actions, and comprises a third motor 51 and a third transmission assembly, and the third motor 51 is in transmission connection with the third transmission assembly, and the third transmission assembly is connected with the two groups of massage assemblies 2 respectively.

[0041] Further referring to Figure 7 , the third transmission assembly comprises a pulley 53, a third transmission shaft 54, two knocking eccentric wheel sets 55 and two knocking rods 56, the third motor 51 is in transmission connection with the third transmission shaft 54 through the pulley 53, the third transmission shaft 54 is provided with the knocking eccentric wheel set 55 at two ends respectively, and each knocking eccentric wheel set 55 is fixedly connected with a knocking rod 56 at the front end, and the other end, i.e. the free end, of the two knocking rods 56 is connected with and pushes a group of massage assemblies 2 respectively.

[0042] Referring toFigure 5 、 Figure 6 The output shaft of the second motor 41 is drivingly connected with the second worm 411. In this embodiment, the output shaft of the second motor 41 is the second worm 411. The second transmission assembly comprises a second worm wheel 42, a second gear 43, a second transmission shaft 44, and two kneading eccentric wheel sets 45. The second worm wheel 42 is engaged with the second worm 411 and drivingly connected with the second motor 41. The second gear 43 is fixed on the second transmission shaft 44 and drivingly connected with the second worm wheel 42. The two kneading eccentric wheel sets 45 are respectively arranged at the two ends of the second transmission shaft 44. The two kneading eccentric wheel sets 45 are drivingly connected with the two massage assemblies 2. The massage assembly 2 is assembled on the kneading eccentric wheel set 45.

[0043] The massage assembly 2 comprises a massage arm 21 and at least one massage head 22 arranged on the massage arm 21. In this embodiment, one massage head 22 is arranged at each end of the transversely arranged massage arm 21. A sleeve joint portion 23 is connected to the middle portion of the massage arm 21 downward and can be sleeved on the kneading eccentric wheel set 45. The free end of the knocking rod 56 is connected to the lower end of the sleeve joint portion 23. The massage arm 21 can be slightly upwardly curved at the two ends.

[0044] The kneading eccentric wheel set 45 comprises two eccentric wheels (a first eccentric wheel 451 and a second eccentric wheel 452) connected with each other. An eccentric connection sleeve 46 with an inclined angle with the second transmission shaft 44 is formed at the connection position of the first eccentric wheel 451 and the second eccentric wheel 452. The sleeve joint portion 23 is sleeved on the eccentric connection sleeve 46. Specifically, the sleeve joint portion 23 can comprise two opposite plate bodies. A through hole 231 for connecting the kneading eccentric wheel set 45 is arranged on the sleeve joint portion 23. A bearing 453 is arranged on the inner wall of the through hole 231 of the eccentric connection sleeve 46 to drivingly connect the sleeve joint portion 23 with the eccentric connection sleeve 46, so that the kneading eccentric wheel set 45 rotates more smoothly.

[0045] When the kneading mechanism 4 is started, the second motor 41 is operated to drive the second worm 411, the second worm wheel 42, the second gear 43, and the second transmission shaft 44 in sequence. Thus, the kneading eccentric wheel sets 45 arranged at the two ends of the second transmission shaft 44 rotate. Since the eccentric connection sleeve 46 has an inclined angle with the second transmission shaft 44, the sleeve joint portion 23 connected with the eccentric connection sleeve 46 can drive the massage arm 21 to make kneading action. Therefore, the kneading eccentric wheel set 45 can drive the massage arm 21 to realize eccentric swing action when it rotates. The two massage arms 21 can realize eccentric swing kneading and reciprocating clamping.

[0046] Preferably, each massage assembly 2 is also connected with an elastic reset member. In the embodiment, the elastic reset member is a tension spring 52, the upper end of the tension spring 52 is connected to the front end of the massage arm 21, and the lower end of the tension spring 52 is connected to the sleeve joint 23. When the knocking massage action is performed, the two ends of the massage arm 21 can be raised relative to the sleeve joint 23, and the elastic reset member can help reset the raised massage head 22 and also can buffer the knocking action. Since the knocking mechanism 5 and the kneading mechanism 4 can operate simultaneously, the free end of the knocking rod 56 and the sleeve joint 23 can be connected by a universal joint structure, for example, a ball head 561 is formed at the front free end of the knocking rod 56, and a spherical cavity (not shown in the figure) for limiting the ball head 561 is formed at the bottom of the sleeve joint 23. The two ends of the knocking rod 56 can form a certain height difference to better drive the massage head 22 at the two ends of the massage arm 21 to rise and fall, forming a high-low action. When the sleeve joint 23 performs the kneading action with the kneading mechanism 4, the angle between the knocking rod 56 and the sleeve joint 23 changes constantly, and the knocking rod 56 can also transmit force to the massage assembly 2 to make the massage arm 21 perform the knocking action.

[0047] When the knocking mechanism 5 is started, the third motor 51 drives the third transmission shaft 54 to rotate through the belt pulley 53, at this time, the knocking eccentric wheel set 55 at the two ends of the third transmission shaft 54 is driven to rotate, so that the knocking rod 56 connected to the eccentric wheel set produces forward and backward displacement, thereby pushing the sleeve joint 23 at the lower end of the massage assembly 2, and making the massage arm 21 at the upper end of the sleeve joint 23 produce forward and backward reciprocating up and down knocking action (the two ends of the massage arm 21 form a high-low seesaw action), at this time, the elastic force provided by the tension spring 52 also plays an auxiliary force-adding role, ensuring that the massage head 22 has sufficient knocking force and buffering effect.

[0048] Referring to Figure 8 As shown in the figure, the first transmission assembly includes a first worm gear 32, a first transmission gear 33, and a walking gear 34, the first worm gear 32 is in transmission connection with the first motor 31, the walking gear 34, the first transmission gear 33, and the first worm gear 32 are sequentially meshed, and the back shell is provided with a rack meshed with the walking gear 34. The output shaft of the first motor 31 is in transmission connection with a first worm 311, in the embodiment, the output shaft of the first motor 31 forms a worm, and the first worm gear 32 is in meshing connection with the first worm 311 to be in transmission connection with the first motor 31.

[0049] In combination Figures 1 to 4As shown, the mounting shell 1 of the embodiment comprises detachably connected upper shell 11 and lower shell 12, the massage assembly 2 passes through the upper shell 11, the walking mechanism 3, the kneading mechanism 4, the knocking mechanism 5 are arranged between the upper shell 11 and the lower shell 12. Therefore, the kneading mechanism 4, the knocking mechanism 5 and the walking mechanism 3 drive the massage assembly 2 to act in the mounting shell 1, so that the massage arm 21 and the massage head 22 of the massage assembly 2 passing through the upper shell 11 part perform kneading and knocking actions, and the walking gear 34 of the walking mechanism 3 is engaged with the rack on the back shell to enable the whole massage core to slide and walk in the back shell. The lower shell 12 has a guide groove 121 on the back, and the back shell is provided with a guide rail (not shown in the figure), when the massage core walks on the back shell, the guide rail is embedded in the guide groove 121, so that the walking path of the massage core does not deviate. In the mounting shell 1, since the three motors independently drive the walking mechanism 3, the kneading mechanism 4 and the knocking mechanism 5 respectively, each mechanism can work independently or simultaneously, and each mechanism is provided with a set of transmission assembly, so that the structure of each set of transmission assembly is simple, and there is no need to design or equip a complex transmission mechanism.

[0050] In addition, in the mounting shell 1, the kneading mechanism 4 is located in the middle of the mounting shell 1, the walking mechanism 3 and the knocking mechanism 5 are respectively located on the two sides of the kneading mechanism 4, and the first transmission assembly and the third transmission assembly are respectively located on the side of the first motor 31 and the third motor 51 and extend to the inside space of the mounting shell 1 and are compactly arranged in the mounting shell 1, so that the arrangement space is reasonably utilized, the structure is more compact, and the overall volume of the massage core is reduced.

[0051] The above is only one embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
