Optionally, the driving assembly 3 further comprises a driving member 31, the driving member 31 being configured to drive the first incomplete bevel gear 32 in rotation. The driving member 31 may be a servo motor, which facilitates the implementation of automatic control. A reduction gearbox 37 can be further arranged between the servo motor and the first incomplete bevel gear 32, so that high-speed rotation of an output shaft of the servo motor can be conveniently converted into low-speed rotation with large torque. The rotation axis of the synchronizing piece 21 can be perpendicular to the output shaft of the servo motor, so that the servo motor can be conveniently placed horizontally, and the vertical occupied space of the massage mechanism is reduced. Meanwhile, the arrangement mode can enable the massage mechanism to be similar to a comb-shaped structure, the synchronous component 2 is located on comb teeth and comb body parts of the comb-shaped structure, the servo motor and the battery for supplying power are located on handle parts of the comb-shaped structure, and the massage mechanism is convenient for a user to hold.

In some embodiments, the driving assembly 3 may include a driving shaft, a second incomplete bevel gear, a third incomplete bevel gear, and a third bevel gear, where the second incomplete bevel gear and the third incomplete bevel gear are disposed on the driving shaft at intervals, the third bevel gear is rotatably disposed in the housing 1, and the third bevel gear is in driving connection with the synchronizing member 21, and when the driving shaft rotates, the third bevel gear can be intermittently meshed with the second incomplete bevel gear or the third incomplete bevel gear, so that the synchronizing member 21 periodically rotates forward and backward. For example, when the second incomplete bevel gear is meshed with the third bevel gear, the third bevel gear rotates in the forward direction, and thus drives the synchronizer 21 to rotate in the forward direction. When the third incomplete bevel gear is meshed with the third bevel gear, the third bevel gear rotates reversely, and then the synchronous piece 21 is driven to rotate reversely.

It will be appreciated that during the period of rotation of the drive shaft, the third bevel gear may not engage with the second incomplete bevel gear nor with the third incomplete bevel gear for a period of time, and the synchronizing member 21 does not rotate at this time, thereby facilitating maintaining the current massage position for a period of time and improving massage comfort and massage effect. The gear tooth structures of the second incomplete bevel gear and the third incomplete bevel gear are within half circle, interference is avoided, and the gear tooth structures of the second incomplete bevel gear and the third incomplete bevel gear can be one third, one fourth, one sixth and the like of a circle of complete gear respectively. The second incomplete bevel gear and the third incomplete bevel gear can be respectively integrally formed with the driving shaft, so that batch processing is facilitated. The two ends of the driving shaft can be respectively erected on the bearing seats in the shell 1, so that the rotation resistance is reduced. The driving shaft can be provided with a key structure, and the second incomplete bevel gear and the third incomplete bevel gear can be respectively provided with key grooves matched with the key structure, so that motion transmission is realized. The driving shaft can rotate in a single direction, thereby simplifying the driving mode of the driving source.

In some embodiments, as shown in fig. 6 and 7, the massage mechanism may further include a connecting rod 39 and a driving disc 38 capable of periodically rotating forward and backward, one end of the connecting rod 39 is rotationally connected to the synchronizing member 21 through a first pivot shaft 391, and the other end is rotationally connected to the driving disc 38 through a second pivot shaft 392, where the first pivot shaft 391 is disposed non-coaxially with the rotation axis of the synchronizing member 21, and the second pivot shaft 392 is disposed non-coaxially with the rotation axis of the driving disc 38. The connecting rod 39, the connection line between the first pivot shaft 391 and the rotation axis of the synchronizing member 21, the connection line between the second pivot shaft 392 and the rotation axis of the driving disc 38, and the connection line between the rotation axis of the synchronizing member 21 and the rotation axis of the driving disc 38 may constitute a double crank mechanism, so that the synchronizing member 21 moves stably. When the driving disk 38 rotates forward, the synchronizing member 21 is rotated forward by the link 39. When the driving disk 38 is reversed, the synchronizing member 21 is reversed by the link 39. The double crank mechanism principle can be applied to the transmission connection of the first bevel gear 33 and the synchronizing piece 21, the driving disc 38 can be connected with the first bevel gear 33, and the driving disc 38 is driven to periodically rotate positively and negatively through the periodic positive and negative rotation of the first bevel gear 33. The driving disc 38 may also be connected to a third bevel gear, and the driving disc 38 is driven to periodically rotate in a forward and reverse direction by the periodic forward and reverse rotation of the third bevel gear. Of course, the drive disk 38 may also be directly driven by an independent periodically reversible drive source.

In some embodiments, the synchronizing member 21 may also be directly driven by a periodically positive and negative driving source, and the massaging mechanism further includes a driving motor drivingly connected to the synchronizing member 21, where the driving motor is capable of periodically positive and negative rotation to drive the synchronizing member 21 to periodically positive and negative rotation. For example, the frequency converter can be used for controlling the driving motor to periodically rotate positively and negatively, by setting the multifunctional terminal, closing one terminal and the public terminal, the frequency converter can drag the motor to rotate positively, closing the other terminal and the public terminal, and the frequency converter can drag the motor to rotate reversely, which is not described in detail herein.
