[0030] In the embodiment, taking the massage machine core for massaging shoulder and neck and trapezius as an example for description.

[0031] Please refer to Figure 1 And Figure 2 , the massage machine core includes cover 300, drive assembly 100 and at least one massage assembly 200, and drive assembly 100 is used to drive massage assembly 200 to carry out massage action.Drive assembly 100 includes shell 110, drive motor 120 and transmission mechanism 130, and drive motor 120 is connected to shell 110 and is used to output power through output shaft.Transmission mechanism 130 is drivingly connected between the output shaft of drive motor 120 and massage assembly 200, and is used to drive massage assembly 200 to carry out massage action under the drive of drive motor 120.Cover 300 is connected to shell 110 and half-encloses massage assembly 200 to protect massage assembly 200.

[0032] The transmission mechanism 130 comprises a first rotating shaft 131 rotatably connected to the housing 110. The driving motor 120 is in transmission connection with the first rotating shaft 131 and is used to drive the first rotating shaft 131 to rotate about a central axis of the first rotating shaft 131, i.e. the central axis of the first rotating shaft 131 coincides with the rotating axis of the first rotating shaft 131. The housing 110 has a mounting cavity 101, and two ends of the first rotating shaft 131 can pass out of the mounting cavity 101 to the outside.

[0033] Please refer to Figure 2 and Figure 3 The massage assembly 200 is connected to one end of the first rotating shaft 131, and comprises an eccentric mechanism 210 and a massage mechanism 220.

[0034] The eccentric mechanism 210 comprises a first eccentric member 211 and a second eccentric member 212, both of which are fixedly connected to the same end of the first rotating shaft 131 and are arranged in sequence along the extension direction of the first rotating shaft 131.

[0035] The massage mechanism 220 comprises a first massage member 221 and a second massage member 222. The first massage member 221 is rotatably connected to the first eccentric member 211 and movably connected to the driving assembly 100, and can be used for massaging the shoulder and neck. The second massage member 222 is rotatably connected to the second eccentric member 212 and movably connected to the driving assembly 100. The central axis of the second eccentric member 212 deviates from the rotating axis of the second massage member 222, and the first included angle a between the central axis of the second eccentric member 212 and the rotating axis of the first rotating shaft 131 is greater than zero. The second massage member 222 can be used for massaging the trapezius muscle. It should be noted that the second eccentric member 212 is in the form of a cylinder as a whole, and the central axis of the second eccentric member 212 is the central axis of the cylindrical portion of the second eccentric member 212.

[0036] When the driving motor 120 drives the first rotating shaft 131 to rotate, the second eccentric member 212 drives the second massage member 222 to perform reciprocating pendulum motion. Since the first included angle a between the central axis of the second eccentric member 212 and the rotating axis of the first rotating shaft 131 is greater than zero, the second massage member 222 can move in the up-down direction while also moving in the left-right direction, thereby expanding the kneading area of the second massage member 222 on the trapezius muscle.

[0037] In other embodiments, the central axis of the first eccentric member 211 can also be parallel to the rotating axis of the first rotating shaft 131, which is not limited here, as long as the central axis of the second eccentric member 212 is arranged at the first included angle a with the rotating axis of the first rotating shaft 131.

[0038] In some embodiments, the central axis of the first eccentric 211 can be the rotation axis of the first massage member 221, the second included angle b between the central axis of the first eccentric 211 and the rotation axis of the first rotation shaft 131 is greater than zero, when the driving motor 120 drives the first rotation shaft 131 to rotate, the first eccentric 211 drives the first massage member 221 to perform the reciprocating swing motion, since the second included angle b between the central axis of the first eccentric 211 and the rotation axis of the first rotation shaft 131 is greater than zero, the first massage member 221 can perform the up-down and left-right four-direction motion on the shoulder and neck, so as to realize the kneading of the shoulder and neck.

[0039] Wherein, the second included angle b is not equal to the first included angle a, in this way, the first massage member 221 and the second massage member 222 can perform the approaching motion and the moving away motion while performing the swing motion respectively, when the first massage member 221 and the second massage member 222 perform the approaching motion, the trapezius muscle can be lifted, so that the user can obtain more abundant massage experience. It should be noted that the first eccentric 211 is in the form of a cylinder as a whole, and the central axis of the first eccentric 211 is the central axis of the cylindrical part of the first eccentric 211.

[0040] Optionally, the third included angle c between the second included angle b and the first included angle a is an acute angle. In this way, it can be ensured that the tilting directions of the first eccentric 211 and the second eccentric 212 are consistent, that is, both of them tilt towards the same direction, so as to improve the consistency of the motion of the first massage member 221 and the second massage member 222, thereby ensuring the consistency of the massage effect of the massage assembly 200.

[0041] Optionally, since the massage amplitude required by the shoulder and neck is larger, the second included angle b is greater than the first included angle a, so that the first massage member 221 can obtain a larger range of motion.

[0042] Further, the third included angle c is less than or equal to 8°. The greater the third included angle c, the greater the amplitude of the approaching motion of the first massage member 221 and the second massage member 222, if the third included angle c is too large, it may cause the first massage member 221 and the second massage member 222 to hold the trapezius muscle too tightly when lifting the trapezius muscle, which brings pain to the user and affects the massage experience, therefore, the third included angle c generally needs to be controlled within 8°, so as to improve the massage comfort. Of course, the third included angle c cannot be too small, the closer the third included angle c to zero, the more synchronized the motion of the first massage member 221 and the second massage member 222, and the smaller the amplitude of the approaching motion, which leads to the failure to lift the trapezius muscle.

[0043] Please refer to Figure 4In some embodiments, the first massage member 221 comprises a first connecting rod 2211 and a first massage head 2212, the first connecting rod 2211 is rotatably connected to the first eccentric member 211, the first massage head 2212 is connected to the first connecting rod 2211 and is used to contact the shoulder and neck, the first connecting rod 2211 is movably connected to the driving assembly 100 through the first movable structure 223, and the first connecting rod 2211 can realize the arrangement of the position of the first massage head 2212, so that the first massage head 2212 can be adapted to the shoulder and neck in use.

[0045] Optionally, the first connecting rod 2211 and the second connecting rod 2221 both extend along a straight line or extend approximately along a straight line. Approximately along a straight line means that the first connecting rod 2211 or the second connecting rod 2221 can have a curved segment, but as a whole, it extends approximately along a straight line.

[0046] Optionally, one end of the first connecting rod 2211 is sleeved on the first eccentric member 211, and the other end is connected to the first massage head 2212. One end of the second connecting rod 2221 is sleeved on the second eccentric member 212, and the other end is connected to the second massage head 2222. In this way, the first massage member 221 and the second massage member 222 can be farthest away from the shell 110, so that the shell 110 can avoid the shoulder and neck and the trapezius muscle, and prevent the shell 110 from interfering with the massage action of the first massage member 221 and the second massage member 222.
