These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0041] This utility model embodiment provides a multifunctional massage mechanism and massager, wherein, as shown in the following example... Figures 1-7 As shown, the multi-functional massage mechanism includes:

[0042] Drive unit 10, drive unit 10 is a power drive device such as a motor; drive unit 10 has a power output shaft 11, and a worm gear (not marked in the figure) is provided on the output shaft 11;

[0043] like Figure 2 As shown, the first actuation system includes a first transmission assembly 20 radially disposed around the power output shaft 11. The first transmission assembly 20 has two branch output paths 21, both of which are connected to the worm gear of the power output shaft 11. Both branch output paths 21 are located on the upper side of the power output shaft 11, and the output direction of the two branch output paths 21 is as follows: Figure 2 In the Z-axis direction shown, each branch output 21 is used to connect to the first massage element 30. The power output shaft 11 drives the two first massage elements 30 to perform kneading motion through the first transmission assembly 20. The connection structure between the branch output 21 and the first massage element 30 and the driving of the first massage element 30 to perform kneading motion can adopt existing technology, which will not be described in detail here.

[0044] The second action system includes a second transmission component 40 that is linked to the first transmission component 20. The second transmission component 40 is located below the first transmission component 20 and is connected to an eccentric mechanism 41.

[0045] Composite motion system, including:

[0046] The second massage member 50 is connected to the eccentric mechanism 41. The second massage member 50 is located on the outer side of the entire movement structure. Figure 2 In the XZ plane direction shown, the second massage member 50 is shaped like a 7. One end of the second massage member 50 is a striking actuator 51, and the other end is a massage part. An eccentric connection part 52 is provided between the striking actuator 51 and the massage part. The eccentric connection part 52 is connected to the eccentric end of the eccentric mechanism 41. The striking actuator 51 is movably connected to the third transmission component 60. The movable connection structure includes, but is not limited to, shaft connection, bearing connection, hinge, etc.

[0047] The third transmission assembly 60 is movably connected to the striking actuator 51. The third transmission assembly 60 is used to link the second massage member 50 and the one-way speed-increasing mechanism 70. The movable connection structure includes, but is not limited to, shaft connection, bearing connection, etc.

[0048] The one-way speed-increasing mechanism 70 is set between the power output path of the drive unit 10 and the third transmission component 60. The one-way speed-increasing mechanism 70 is linked to the power output shaft 11 in one of the rotation directions, either in reverse or forward rotation. The one-way speed-increasing mechanism 70 includes, but is not limited to, a structure combining planetary gears and one-way bearings, a synchronous belt one-way speed-increasing structure, and a gear one-way speed-increasing structure.

[0049] When the power output shaft 11 rotates in the first rotation direction (e.g., forward rotation) or the second rotation direction (e.g., reverse rotation), the first motion system drives the first massage element 30 to move, and the second motion system drives the second massage element 50. Due to the combined action of the third transmission component 60 limiting one end of the second massage element 50 and the eccentric mechanism 41, the massage end of the second massage element 50 reciprocates within the set area in the XZ plane direction to achieve a kneading effect, thereby generating the first massage mode of the second massage element 50. At this time, the one-way speed-increasing mechanism 70 is locked and does not move.

[0050] When the power output shaft 11 rotates in the second rotation direction (e.g., reverse), the one-way speed-increasing mechanism 70 is triggered to start due to its one-way linkage characteristic. The speed-increasing mechanism 70 drives the tapping actuator 51 to generate a tapping action superimposed on the first massage mode, providing the user with the best massage experience.

[0051] The aforementioned transmission components include, but are not limited to, gear connection structures, pulley connection structures, and connecting rod connection structures.

[0052] The multifunctional massage mechanism provided in this embodiment of the invention drives various systems and mechanisms through a single power output shaft 11 of the drive unit 10. This effectively compresses the space along the axial direction of the drive unit 10. Furthermore, through the synergistic action of the first action system, the second action system, and the composite action system, it achieves the effect of two massage functions on a single massage head. The multifunctional massage mechanism provided in this embodiment of the invention achieves multiple massage effects while maintaining a compact overall size and small overall dimensions.

[0053] In specific implementation, such as Figure 2 , Figure 3 ,picture, Figure 5As shown, the split output branch 21 includes a first gear set 211 and a second gear set 212, both of which are double reduction gears; the power output shaft 11 drives the first massage element 30 to move through the first gear set 211 and the second gear set 212 in sequence.

[0054] Keep the upper second gear set 212 horizontal, and tilt the end of the first gear set 211 that is linked with the second gear set 212 upward. The tilt angle can be adjusted as needed, which will not be elaborated here, thereby compressing the space.

[0055] In specific implementation, such as Figure 2 , Figure 5 As shown, the drive unit 10 is provided with a second transmission assembly 40 on both sides; the second transmission assembly 40 is located in the space below the first transmission assembly 20; the second transmission assembly 40 includes an eccentric mechanism 41, a first bevel gear 42, a first connecting rod 43, a second bevel gear 44, a third bevel gear 45, and a second connecting rod 46; the eccentric mechanism 41 is an eccentric wheel;

[0056] like Figure 5 As shown, the first link 43 is located on the side of the drive unit 10, and the first link 43 is arranged along the axial direction of the power output shaft 11. The second link 46 is arranged along the radial direction of the power output shaft 11 in the length direction.

[0057] The output bevel gear of the second gear set 212 is as follows: Figure 4 As shown; the output end of the second gear set 212 meshes with the first bevel gear 42; the first bevel gear 42 extends the second bevel gear 44 to one side of the drive unit 10 body through the first connecting rod 43;

[0058] The second connecting rod 46 is located in the radial direction of the first connecting rod 43. One end of the second connecting rod 46 is provided with a third bevel gear 45, and the other end is provided with an eccentric mechanism 41. The eccentric end of the eccentric mechanism 41 is connected to the second massage component 50. The transmission structure formed by the first bevel gear 42, the first connecting rod 43, the second bevel gear 44, the third bevel gear 45, and the second connecting rod 46 is compact.

[0059] In specific implementation, the output end of the second gear set 212 and the first bevel gear 42 form a reduction gear set structure; the second bevel gear 44 and the third bevel gear 45 form a speed-increasing gear set structure. In this embodiment, by setting a multi-stage reduction and speed-increasing gear transmission structure, on the one hand, while meeting the massage driving force, a more compact drive motor can be used, thereby reducing the space occupied by the drive motor; on the other hand, compared with other transmission structures, the entire second transmission assembly 40 has a more compact structure, which can meet the design requirements of product miniaturization. In this embodiment, the reduction ratio configuration of the gear set is sufficient to ensure that the tapping speed of the second massage element 50 is greater than the kneading speed, which will not be elaborated here;

[0060] In specific implementation, the third transmission component 60 is a connecting arm structure. One end of the third transmission component 60 is connected to the movable shaft of the striking actuator 51 or a bearing, and the other end is connected to the output shaft of the unidirectional speed-increasing mechanism 70 or a bearing.

[0061] In specific implementation, the one-way speed-increasing mechanism 70 includes a one-way bearing 71, a speed-increasing planetary gear 72, and a first transmission shaft 73;

[0062] The first drive shaft 73 is located radially on the power output shaft 11. A helical gear 74 is located in the middle of the first drive shaft 73, and the helical gear 74 meshes with the worm gear of the power output shaft 11. One-way bearings 71 are respectively provided on both axial sides of the first drive shaft 73. The one-way bearings 71 are existing products, which allow rotation in one direction and lock in the opposite direction. The one-way bearings 71 are connected to the input end of the speed-increasing planetary gear 72, and the output end of the speed-increasing planetary gear 72 is connected to the shaft of the third transmission assembly 60 through the second drive shaft 75. The speed-increasing planetary gear used in this embodiment is an existing product, and its structure and working principle are existing technologies, which will not be described in detail here. This product is a compact product, and the use of the speed-increasing planetary gear 72 can further reduce space and meet the installation requirements in more confined spaces.

[0063] The multifunctional massage mechanism provided in this embodiment of the utility model, through the reasonable layout and structural design of the first action system, the second action system and the composite action system, makes the structure of the entire massage mechanism more compact and small.

[0064] Another massager provided in this embodiment of the utility model employs any of the multifunctional massage mechanisms described above, including a housing 90. Two elongated first travel holes 91 are provided in the middle of the upper surface of the housing 90, and two elongated second travel holes 92 are provided near the side wall. A first massage element 30 passes through the first travel holes 91 and connects to the mechanism, and a second massage element 50 passes through the second travel holes 92 and connects to the mechanism.

One end of the first massage member 30 is provided with a groove for installing the intermediate connector 31. The intermediate connector 31 is installed on the rocking slope 2121 and is movable between the intermediate connector 31 and the first massage member 30. When the intermediate connector 31 rotates under the drive of the rocking slope 2121, the first massage member 30 moves within the first stroke hole 91 under the limiting action of the first stroke hole 91, thereby realizing the set massage action.
