[0080] As described in the background section of this application, with the increasing health awareness and faster pace of life, the market demand for massage devices, as a convenient health care tool, is gradually growing. At the same time, continuous technological innovation and upgrading are also driving the continuous improvement of the functions and performance of massage device products to meet the diverse needs of consumers.

[0081] Massage devices typically include two sets of massage heads spaced apart. However, in related technologies, because the spacing between the two sets of massage heads is fixed and not adjustable, this results in a small massage coverage area, poor adaptability to users of different body types, and a tendency to cause chafing, leading to a poor user experience.

[0082] Example 1

[0083] In view of the above-mentioned problems, this application provides a massage mechanism to solve the problem that the spacing between the two sets of massage heads is fixed and cannot be adjusted in the related art.

[0084] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0085] like Figure 1As shown, the massage mechanism 100 includes a massage mechanism and a spacing adjustment mechanism. The massage mechanism includes a massage drive 1, a massage drive shaft 2, and at least two massage components 3. The at least two massage components 3 are movably arranged along the axial direction of the massage drive shaft 2 and connected to it. Each massage component 3 includes a massage head 31. The massage drive 1 drives at least one massage component 3 to move, thereby actuating the massage head 31.

[0086] The spacing adjustment mechanism includes a spacing adjustment drive 4 and a spacing adjustment shaft 5. At least one massage component 3 is connected to the spacing adjustment shaft 5. The spacing adjustment drive 4 is used to drive at least one massage component 3 to move axially along the massage drive shaft 2 via the spacing adjustment shaft 5.

[0087] In this application, since the massage component 3 includes a massage head 31, and since the massage drive 1 is used to drive at least one massage component 3 to move, the massage head 31 in at least one massage component 3 can be driven to move by the massage drive 1, and the moving massage head 31 can perform massage.

[0088] Furthermore, since at least two massage components 3 connected to the massage drive shaft 2 are movably arranged along the axial direction of the massage drive shaft 2, and at least one massage component 3 is drively connected to the spacing adjustment shaft 5, and since the spacing adjustment drive 4 is used to drive at least one massage component 3 to move along the axial direction of the massage drive shaft 2 via the spacing adjustment shaft 5, the spacing adjustment shaft 5 can be driven by the spacing adjustment drive 4 to move at least one massage component 3 along the axial direction of the massage drive shaft 2, thereby achieving the adjustment of the spacing between the massage heads 31. Thus, by adjusting the spacing between the massage heads 31, firstly, the spacing between the massage heads 31 can be adapted to users of different body types, which is beneficial to enhancing applicability; secondly, the massage heads 31 can massage different positions according to different massage needs, thereby increasing the massage coverage area; thirdly, it helps to avoid massaging the same area for too long, thus helping to avoid phenomena such as chafing, which is beneficial to enhancing comfort and ultimately enhancing the user experience.

[0089] In this embodiment, the massage drive 1 and the spacing adjustment drive 4 can be any of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The selection of the massage drive 1 and the spacing adjustment drive 4 is flexible. Specifically, they can be selected according to actual needs. This embodiment does not impose any specific limitations on this.

[0090] In a preferred embodiment, the massage drive 1 is used to drive the movement of all the massage components 3. This arrangement helps to reduce the number of drive components that drive the movement of the massage components 3, which not only simplifies the composition of the massage mechanism 100, but also helps to reduce the manufacturing cost of the massage mechanism 100.

[0091] In other embodiments, the massage drive 1 can be used to drive the movement of one part of the massage component 3, while another part of the massage component 3 can be driven by other drive components. This arrangement allows different drive components to drive the corresponding massage component 3, thereby improving the flexibility of the massage component 3's movement and thus enhancing the flexibility and diversity of the massage.

[0092] In a preferred embodiment, such as Figure 1 As shown, each massage component 3 is connected to the pitch adjustment shaft 5 via a drive mechanism.

[0093] With this configuration, the spacing adjustment drive 4 can drive each massage component 3 to move axially along the massage drive shaft 2 via the spacing adjustment shaft 5. This improves, firstly, the efficiency of spacing adjustment between the massage heads 31; secondly, it increases the spacing adjustment range between the massage heads 31, allowing the spacing between the massage heads 31 to better suit users of different body types, thus enhancing applicability and increasing the massage coverage; and thirdly, it prevents each massage head 31 from massaging the same area for too long, thereby preventing chafing and enhancing comfort and user experience.

[0094] For the spacing adjustment mechanism, further, such as Figure 1 and Figure 2 As shown, the spacing adjustment mechanism includes at least one adjustment transmission member 6 connected to the spacing adjustment shaft 5. The at least one adjustment transmission member 6 is connected to at least one massage component 3 in a one-to-one correspondence, so that at least one massage component 3 is connected to the spacing adjustment shaft 5 through the corresponding adjustment transmission member 6.

[0095] Since the massage component 3 is connected to the massage drive shaft 2, the transmission component 6 is adjusted to achieve the transmission connection between the massage component 3 and the spacing adjustment shaft 5. This helps to increase the arrangement distance between the massage drive shaft 2 and the spacing adjustment shaft 5, and thus helps to avoid interference between the components on the massage drive shaft 2 and the spacing adjustment shaft 5.

[0096] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, since each massage component 3 is connected to the pitch adjustment shaft 5, the number of adjustment transmission components 6 is the same as the number of massage components 3, and each massage component 3 is connected to the pitch adjustment shaft 5 through the adjustment transmission component 6.

[0097] This arrangement helps to ensure a large spacing between the massage drive shaft 2 and the spacing adjustment shaft 5, which in turn helps to further avoid interference between the components on both the massage drive shaft 2 and the spacing adjustment shaft 5.

[0098] In other embodiments, each massage component 3 is directly connected to the spacing adjustment shaft 5. This configuration simplifies the structure of the massage mechanism 100 by eliminating the need for an adjustment transmission component 6, thus facilitating its manufacturing and reducing manufacturing costs.

[0099] Furthermore, in a preferred embodiment, such as Figure 3 As shown, there are two massage components 3, namely the first massage component 32 and the second massage component 33. There are also two adjustment transmission components 6, namely the first adjustment transmission component 61 and the second adjustment transmission component 62. The first adjustment transmission component 61 is connected to the first massage component 32, and the second adjustment transmission component 62 is connected to the second massage component 33.

[0100] The spacing adjustment drive 4 is used to drive the spacing adjustment shaft 5 to rotate, such as Figure 3 As shown, the pitch adjustment shaft 5 is provided with a first threaded section 51 and a second threaded section 52 with opposite rotation directions. The first adjustment transmission member 61 is threadedly connected to the first threaded section 51, and the second adjustment transmission member 62 is threadedly connected to the second threaded section 52.

[0101] With this configuration, when the spacing adjustment drive 4 drives the spacing adjustment shaft 5 to rotate, the spacing adjustment shaft 5 will drive the first adjustment transmission 61 and the second adjustment transmission 62 to move away from each other or closer to each other through the first threaded section 51 and the second threaded section 52 with opposite rotation directions. In turn, the first adjustment transmission 61 and the second adjustment transmission 62 can drive the first massage component 32 and the second massage component 33 to move towards or away from each other in the axial direction of the massage drive shaft 2. This allows the massage heads 31 in the first massage component 32 and the second massage component 33 to move closer to each other or further away from each other, thereby realizing the spacing adjustment between the massage heads 31.

[0102] The rotating pitch adjustment shaft 5 drives the massage component 3 to move axially along the massage drive shaft 2 via its threaded section. In this way, the pitch adjustment shaft 5 does not need to move axially, which helps to reduce the space occupied by the pitch adjustment shaft 5 in its own axial direction and helps to achieve a compact design of the massage mechanism 100.

[0103] Because the threaded drive itself has high precision, the spacing adjustment shaft 5 drives the first massage component 32 and the second massage component 33 to move towards or away from each other through two threaded sections with opposite directions. This allows for accurate control of the relative distance between the first massage component 32 and the second massage component 33, and consequently, accurate control of the spacing between the massage heads 31. Furthermore, providing two massage components 3 not only meets massage needs but also simplifies the structure of the massage mechanism 100 to some extent.

[0104] In other embodiments, the spacing adjustment drive 4 can also be used to drive the spacing adjustment shaft 5 to move along its own axial direction, thereby driving the massage assembly 3 to move along the axial direction of the massage drive shaft 2. This configuration simplifies the structure of the spacing adjustment shaft 5 to some extent and facilitates its processing.

[0105] In other embodiments, the massage component 3 may be provided in three, four or more. The number of massage components 3 is set flexibly. Specifically, it can be set according to actual usage needs. This embodiment does not make a specific limitation in this regard.

[0106] For massage component 3, further, such as Figure 1 , Figure 2 and Figure 4 As shown, the massage assembly 3 also includes a massage rod 34 and a massage transmission structure 35. The massage rod 34 is connected to the massage head 31, and the massage transmission structure 35 is connected between the massage rod 34 and the massage drive shaft 2. The massage transmission structure 35 is movably arranged along the axial direction of the massage drive shaft 2 so that the massage assembly 3 is movably arranged along the axial direction of the massage drive shaft 2.

[0107] The adjusting transmission component 6 and the massage transmission structure 35 are axially limited to each other on the massage drive shaft 2 so that the massage assembly 3 is connected to the adjusting transmission component 6.

[0108] The massage component 3 is connected to the adjusting transmission component 6 by adjusting the axial limiting fit between the transmission component 6 and the massage transmission structure 35. Since this limiting fit connection method has good stability, on the one hand, it can accurately transmit the power of the adjusting transmission component 6 to the massage component 3, ensuring that the massage component 3 operates as expected; on the other hand, during the massage process, this connection method can prevent unnecessary displacement or shaking of the massage component 3 in the axial direction, thereby improving the reliability and durability of the entire massage mechanism 100.

[0109] Furthermore, such as Figure 2 and Figure 5 As shown, the adjusting transmission component 6 includes a sleeve 63 and a connecting arm 64 protruding from the outer side wall of the sleeve 63. The sleeve 63 is sleeved on the outer side of the massage transmission structure 35 and is axially limited to the massage transmission structure 35 on the massage drive shaft 2. The connecting arm 64 is connected to the spacing adjustment shaft 5.

[0110] This design has two advantages. First, the sleeve 63, along its entire circumference, increases the axial limiting range of the adjustment transmission component 6 and the massage transmission structure 35, thereby enabling the adjustment transmission component 6 to more stably drive the massage assembly 3 along the axial direction of the massage drive shaft 2. Second, the connecting arm 64 facilitates the connection between the adjustment transmission component 6 and the spacing adjustment shaft 5, and to a certain extent, prevents the structure connecting the adjustment transmission component 6 to the spacing adjustment shaft 5 from becoming too large, thus reducing the space occupied by the adjustment transmission component 6 and facilitating its installation in the massage mechanism 100.

[0111] In other embodiments, the adjusting transmission member 6 may also include a semi-enclosed structure and a connecting arm connected to this structure. The semi-enclosed structure, for example, is a half-cylinder, and this semi-enclosed structure is axially positioned with the massage transmission structure 35, while the connecting arm is connected to the spacing adjustment shaft 5. This arrangement helps reduce the volume of the adjusting transmission member 6, thereby reducing the space occupied by the adjusting transmission member 6 and further facilitating its installation within the massage mechanism 100.

[0112] Furthermore, such as Figure 6 As shown, the massage mechanism 100 also includes a mechanism housing 7, and the adjusting transmission component 6 is also axially guided and engaged with the mechanism housing 7 on the spacing adjustment shaft 5.

[0113] This configuration, by adjusting the axial guiding fit between the transmission component 6 and the mechanism housing 7 on the pitch adjustment shaft 5, helps to enhance the stability of the movement of the transmission component 6 on the pitch adjustment shaft 5.

[0114] Furthermore, such as Figure 5 and Figure 6 As shown, a guide protrusion 65 is also provided on the outer side wall of the sleeve 63. The guide protrusion 65 is used to guide and cooperate with the movement housing 7 in the axial direction of the pitch adjustment shaft 5.

[0115] The guide protrusion 65 guides and engages with the movement housing 7, which to a certain extent helps to create a relatively small guiding engagement area between the adjusting transmission component 6 and the movement housing 7. This, in turn, helps to create a relatively small frictional force between the adjusting transmission component 6 and the movement housing 7, thereby reducing wear on the adjusting transmission component 6 and the movement housing 7 and extending their service life.

[0116] In other embodiments, the outer wall of the sleeve 63 is guided to the movement housing 7 in the axial direction of the pitch adjustment shaft 5. This arrangement simplifies the structure of the adjustment transmission member 6 by eliminating the need for the guide protrusion 65, thus facilitating its machining. Furthermore, it increases the guiding contact area between the adjustment transmission member 6 and the movement housing 7, thereby further enhancing the stability of the adjustment transmission member 6's axial movement along the pitch adjustment shaft 5.

[0117] Furthermore, such as Figure 5 and Figure 6 As shown, the guide protrusion 65 is T-shaped, and the mechanism housing 7 is provided with a T-shaped groove 71 that is adapted to the guide protrusion 65. The T-shaped groove 71 allows the guide protrusion 65 to be inserted and guides the guide protrusion 65 in the axial direction of the spacing adjustment shaft 5.

[0118] Since the T-groove 71 can prevent the guide protrusion 65 from falling out of the T-groove 71, the guide engagement between the T-shaped guide protrusion 65 and the T-groove 71 helps to further enhance the stability of the adjustment transmission component 6 in the axial movement of the pitch adjustment shaft 5.

[0119] In other embodiments, the guide protrusion 65 may also be rectangular or dovetail-shaped. When the guide protrusion 65 is rectangular, the movement housing 7 may have a rectangular groove or a guide plane that guides and engages with the guide protrusion 65. When the guide protrusion 65 is dovetail-shaped, the movement housing 7 may have a dovetail-shaped groove that guides and engages with the guide protrusion 65. The structure of the guide protrusion 65 is flexible and can be configured according to actual usage requirements.

[0120] Regarding the arrangement of the guide protrusion 65 and the connecting arm 64 on the sleeve 63, further, as Figure 5 As shown, the guide protrusion 65 and the connecting arm 64 are located on opposite sides of the sleeve 63.

[0121] This design helps to distribute the force more evenly on the adjusting transmission component 6, which in turn helps to make the adjusting transmission component 6 move more smoothly.

[0122] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the massage head 31 includes a first massage head 311, the massage rod 34 includes a first massage rod 341 connected to the first massage head 311, and the sleeve 63 has a first clearance hole 631 on its side wall for the first massage rod 341 to pass through the sleeve 63 from the inside to the outside.

[0123] If the weight of one of the guide protrusion 65 and the connecting arm 64 is greater than the weight of the other, the first clearance hole 631 is positioned close to the heavier one of the guide protrusion 65 and the connecting arm 64.

[0124] The first clearance hole 631 is provided to facilitate the first massage rod 341 to pass through the sleeve 63 from the inside to the outside. The first clearance hole 631 is located close to the heavier one of the guide protrusion 65 and the connecting arm 64. This helps to make the weight distribution of the adjusting transmission component 6 more even, which in turn helps to make the axial movement of the adjusting transmission component 6 smoother and reduces the wear of the adjusting transmission component 6.

[0125] Furthermore, the first clearance hole 631 is an elongated hole, and the length of the first clearance hole 631 extends along the axial direction of the massage drive shaft 2. The first clearance hole 631 and the first massage rod 341 are engaged in the upper limit of the width direction of the first clearance hole 631.

[0126] With this configuration, the first massage rod 341 can be limited in its swing amplitude by the limiting cooperation between the first clearance hole 631 and the first massage rod 341 in the width direction, which in turn can limit the swing amplitude of the first massage head 311 in this direction, thus making the first massage head 311 massage more stably in this direction.

[0127] Furthermore, the first massage rod 341 includes an insertion section inserted into the sleeve 63, the length of which is 1 / 6 to 1 / 4 of the total length of the first massage rod 341.

[0128] This design serves two purposes. First, the length range provides sufficient support between the first massage rod 341 and the sleeve 63, preventing excessive wobbling or displacement of the first massage rod 341, thus ensuring the accuracy and stability of the massage action. Second, this length range helps reduce deformation of the first massage rod 341 during operation, improving the structural reliability of the first massage rod 341.

[0129] In this embodiment, the length of the insertion segment can be any value within the range of 1 / 6, 1 / 4, or 1 / 6-1 / 4 of the total length of the first massage rod 341. The ratio between the insertion segment and the total length of the first massage rod 341 is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not impose any specific limitations on this.

[0130] like Figure 4 As shown, the first massage head 311 is located outside the core housing 7, the massage transmission structure 35 is located inside the core housing 7, and the core housing 7 is provided with a second clearance hole 72 for the first massage rod 341 to pass through the core housing 7 from the inside to the outside.

[0131] The second clearance hole 72 is an elongated hole, and the length of the second clearance hole 72 extends along the axial direction of the massage drive shaft 2. The second clearance hole 72 and the first massage rod 341 are engaged in the upper limit of the width direction of the second clearance hole 72.

[0132] With this configuration, since the lengths of the first clearance hole 631 and the second clearance hole 72 both extend along the axial direction of the massage drive shaft 2, and since the width direction is usually perpendicular to the length direction, the width direction of the first clearance hole 631 and the width direction of the second clearance hole 72 are in the same direction. In this way, the swing amplitude of the first massage rod 341 can be further limited through the second clearance hole 72 in the width direction of the hole, which in turn can further limit the swing amplitude of the first massage head 311 in this direction, which is conducive to making the first massage head 311 massage more stably in this direction.

[0133] For sleeve 63, further, as Figure 5 As shown, multiple weight-reducing grooves 632 or weight-reducing holes are provided on the outer wall of the sleeve 63.

[0134] This configuration, through the weight reduction groove 632 or weight reduction hole, helps to reduce the weight of the adjustment transmission component 6, thereby facilitating the lightweight design of the adjustment transmission component 6.

[0135] In a preferred embodiment, such as Figure 5 As shown, multiple weight-reducing grooves 632 are provided on the outer wall of the sleeve 63.

[0136] This design, through the weight reduction groove 632, not only helps to reduce the weight of the adjusting transmission component 6, but also helps to ensure the structural strength of the adjusting transmission component 6 to a certain extent.

[0137] For the massage transmission structure 35, further, such as Figure 2 and Figure 4 As shown, the massage transmission structure 35 includes a slanted shaft wheel 351, which is connected to the massage drive shaft 2. The slanted shaft wheel 351 includes a slanted shaft segment 3511 that extends axially in a direction different from that of the massage drive shaft 2.

[0138] The first massage rod 341 is connected to the inclined shaft section 3511. The massage drive 1 is used to drive the massage drive shaft 2 to rotate. The massage drive shaft 2 is used to drive the inclined shaft section 3511 to rotate eccentrically around the central axis of the massage drive shaft 2 when rotating, so that the inclined shaft section 3511 drives the first massage head 311 to swing through the first massage rod 341.

[0139] With this configuration, the inclined shaft wheel 351 drives the first massage head 311 to swing through the eccentric rotation of the inclined shaft segment 3511, which can produce a variety of massage angles and intensity changes, thereby enriching the massage effect and enhancing the massage experience. At the same time, compared with the traditional linear motion massage method, this swinging massage is more conducive to covering the massage area more comprehensively and providing a more uniform and deeper massage experience.

[0140] Furthermore, such as Figure 2 and Figure 4As shown, the massage transmission structure 35 also includes an eccentric wheel 352, which is connected to the massage drive shaft 2. The eccentric wheel 352 includes an eccentric part 3521 whose center is offset from the central axis of the massage drive shaft 2.

[0141] like Figure 1 and Figure 6 As shown, the massage head 31 also includes a second massage head 312, and the massage rod 34 also includes a second massage rod 342 connected to the second massage head 312. The second massage rod 342 is connected to the eccentric part 3521. The massage drive shaft 2 is used to drive the eccentric part 3521 to rotate eccentrically around the central axis of the massage drive shaft 2 when rotating, so that the eccentric part 3521 drives the second massage head 312 to move closer to or away from the first massage head 311 through the second massage rod 342.

[0142] With this configuration, the eccentric rotation of the eccentric part 3521 of the eccentric wheel 352 drives the second massage head 312 to move closer to or further away from the first massage head 311, enabling pinching or stretching massage movements. This facilitates deeper stimulation and relaxation of muscles and tissues during body massage, thereby enhancing the massage effect. Furthermore, it enriches the massage effect based on the oscillating massage of the first massage head 311, thus further enhancing the user experience.

[0143] Furthermore, such as Figure 2 and Figure 4 As shown, the massage transmission structure 35 is connected to the axial end of the massage drive shaft 2. Specifically, the eccentric wheel 352 is connected to the axial end of the massage drive shaft 2, and the inclined shaft wheel 351 is connected to the eccentric wheel 352 and is located on the side of the eccentric wheel 352 away from the massage drive shaft 2.

[0144] This design reduces the axial length of the massage drive shaft 2, which on the one hand helps to reduce the weight of the massage mechanism 100, and on the other hand helps to reduce the space occupied by the massage drive shaft 2, making the massage mechanism 100 more compact.

[0145] In other embodiments, the massage drive shaft 2 can pass through the entire massage transmission structure 35 along its own axis. Specifically, the massage drive shaft 2 passes through the inclined shaft wheel 351 and the eccentric wheel 352 along its own axis, and the inclined shaft wheel 351 and the eccentric wheel 352 are directly connected to the massage drive shaft 2.

[0146] With this configuration, since the inclined shaft wheel 351 and the eccentric wheel 352 are directly connected to the massage drive shaft 2, the reliability of the massage drive shaft 2 driving the inclined shaft wheel 351 and the eccentric wheel 352 can be guaranteed, thereby ensuring the reliability of the massage mechanism 100 in operation.

[0147] Furthermore, such as Figure 2 and Figure 4 As shown, the eccentric wheel 352 is fixedly connected to the axial end of the massage drive shaft 2, and the inclined shaft wheel 351 is movably connected to the eccentric wheel 352 along the axial direction of the massage drive shaft 2, so that the massage transmission structure 35 is movably arranged along the axial direction of the massage drive shaft 2.

[0148] The adjusting transmission component 6 and the inclined shaft wheel 351 are engaged at the upper limit of the axial direction of the massage drive shaft 2. The adjusting transmission component 6 is used to drive the inclined shaft wheel 351 to move along the axial direction of the massage drive shaft 2 through the above-mentioned limiting engagement, so as to drive the first massage head 311 to move along the axial direction of the massage drive shaft 2.

[0149] This configuration, with the eccentric wheel 352 fixedly connected to the axial end of the massage drive shaft 2, facilitates the transmission connection between the massage transmission structure 35 and the massage drive shaft 2, while also ensuring the reliability of the transmission connection between the massage transmission structure 35 and the massage drive shaft 2.

[0150] The slanted wheel 351 is movably connected to the eccentric wheel 352 along the axial direction of the massage drive shaft 2. In this way, the adjustment transmission component 6 only needs to drive the slanted wheel 351 to move along the axial direction of the massage drive shaft 2, and thus only needs to drive the first massage head 311 to move along the axial direction of the massage drive shaft 2. This reduces the number of axially moving parts in the massage assembly 3, thereby reducing the weight of axial movement in the massage assembly 3 and facilitating the adjustment of the spacing of the massage heads 31.

[0151] In other embodiments, the eccentric wheel 352 is movably connected to the massage drive shaft 2 along the axial direction of the massage drive shaft 2, and the inclined shaft wheel 351 is also movably arranged along the axial direction of the massage drive shaft 2. In this case, under the drive of the adjusting transmission member 6, both the first massage head 311 and the second massage head 312 can move along the axial direction of the massage drive shaft 2, thereby adjusting the distance between the first massage head 311 and the second massage head 312. Alternatively, the eccentric wheel 352 is movably connected to the massage drive shaft 2 along the axial direction of the massage drive shaft 2, and the inclined shaft wheel 351 is fixedly arranged along the axial direction of the massage drive shaft 2. In this case, under the drive of the adjusting transmission member 6, the second massage head 312 can move along the axial direction of the massage drive shaft 2, thereby adjusting the distance between the second massage heads 312.

[0152] As can be seen from the above, the axial movement of both the eccentric wheel 352 and the inclined shaft wheel 351 is quite flexible, and can be set according to actual usage requirements.

[0153] Furthermore, such as Figure 2 As shown, a first groove 3522 is provided on the end face of the eccentric wheel 352 near the inclined shaft wheel 351, and the groove depth of the first groove 3522 extends along the axial direction of the massage drive shaft 2.

[0154] The inclined shaft wheel 351 also includes an insertion shaft section 3512 that inserts into the first groove 3522. The insertion shaft section 3512 is movably disposed within the first groove 3522 along the axial direction of the massage drive shaft 2, so that the inclined shaft wheel 351 is movably connected to the eccentric wheel 352 along the axial direction of the massage drive shaft 2. The insertion shaft section 3512 engages with the first groove 3522 to prevent rotation, so that the eccentric wheel 352 drives the inclined shaft wheel 351 to rotate.

[0155] With this configuration, firstly, the eccentric wheel 352 and the inclined wheel 351 are movably connected by the cooperation of the inserted shaft segment 3512 and the first groove 3522. Compared with other complex connection methods, no additional connecting parts or guide structures are required, which helps to make the entire massage transmission structure 35 more compact and simple.

[0156] Secondly, during the assembly process, simply inserting the insertion shaft section 3512 into the first groove 3522 is sufficient to connect the inclined shaft wheel 351 and the eccentric wheel 352, making the operation convenient and quick.

[0157] Thirdly, the anti-rotation fit between the inserted shaft segment 3512 and the first groove 3522 ensures that the eccentric wheel 352 can stably drive the inclined shaft wheel 351 to rotate. At the same time, the fit between the inserted shaft segment 3512 and the first groove 3522 satisfies the axial movement requirement and ensures the reliability of power transmission. The anti-rotation fit can prevent slippage or power interruption between the two, so that the massage action can be carried out continuously and stably.

[0158] In other embodiments, a guide groove is provided on the eccentric wheel 352, and the guide groove extends axially along the massage drive shaft 2. A slider that cooperates with the guide groove is mounted on the inclined shaft wheel 351. This allows the slider to slide freely on the guide groove, thereby enabling the inclined shaft wheel 351 to move axially relative to the eccentric wheel 352. Simultaneously, the anti-rotation cooperation between the guide groove and the slider ensures that the eccentric wheel 352 drives the inclined shaft wheel 351 to rotate.

[0159] This configuration, through the cooperation of the guide groove and the slider, facilitates the movable connection between the slanted wheel 351 and the eccentric wheel 352, while also ensuring normal transmission between the slanted wheel 351 and the eccentric wheel 352.

[0160] Furthermore, the insertion shaft segment 3512 is a flat shaft segment, and the first groove 3522 is a flat groove adapted to the shape of the insertion shaft segment 3512.

[0161] This configuration, firstly, enables a stable anti-rotation fit between the insertion shaft segment 3512 and the first groove 3522. This stable anti-rotation fit ensures the accuracy and continuity of power transmission, avoiding fluctuations in massage intensity and rhythm due to unstable rotation.

[0162] Secondly, due to the large contact area and tight fit of the flat structure, when the eccentric wheel 352 drives the slant wheel 351 to rotate, the torque can be transmitted from the eccentric wheel 352 to the slant wheel 351 more efficiently, which can reduce the energy loss in the transmission process and enable the massage component 3 to output stronger and more stable massage power.

[0163] Thirdly, from a machining perspective, the machining of flat shaft segments and flat grooves is relatively simple. Compared to complex irregular structures, machining flat shapes only requires conventional milling, planing, and other machining processes, without the need for special tools or complex machining paths. This helps to reduce machining costs and improve machining efficiency.

[0164] In other embodiments, the insertion shaft segment 3512 can be a rectangular shaft segment or a triangular shaft segment, and correspondingly, the first groove 3522 can be a rectangular groove or a triangular groove. The shape and structure of the insertion shaft segment 3512 and the first groove 3522 are relatively flexible and can be set according to actual usage requirements.

[0165] The eccentric wheel 352 is connected to the massage drive shaft 2 by a screw. The screw includes a head and a rod. The length of the rod extends along the axial direction of the massage drive shaft 2, and the head is located in the first groove 3522.

[0166] like Figure 2 As shown, an avoidance groove 3513 is provided on the axial end face of the insertion shaft segment 3512 near the bottom wall of the first groove 3522. The avoidance groove 3513 is used to avoid the head so that the axial end face of the insertion shaft segment 3512 contacts the bottom wall surface of the first groove 3522.

[0167] This configuration serves two purposes. First, by connecting the eccentric wheel 352 to the massage drive shaft 2 with screws, the reliability of the connection between the eccentric wheel 352 and the massage drive shaft 2 is ensured, thereby guaranteeing the reliability of the transmission between them. Second, by using the clearance groove 3513 to avoid the screw head, while ensuring sufficient axial movement distance for the inclined shaft wheel 351, the screw head is prevented from causing a large axial dimension of the massage mechanism 100 on the massage drive shaft 2. This allows the massage mechanism 100 to have a relatively small axial dimension on the massage drive shaft 2, facilitating a miniaturized design.

[0168] like Figure 2 As shown, a second groove 3523 is provided on the end face of the eccentric wheel 352 near the end of the massage drive shaft 2, and one axial end of the massage drive shaft 2 is inserted into the second groove 3523.

[0169] This configuration helps to enhance the stability of the connection between the eccentric wheel 352 and the massage drive shaft 2, and in turn, enhances the stability of the transmission between the eccentric wheel 352 and the massage drive shaft 2.

[0170] Furthermore, the first groove 3522 is in a first direction perpendicular to its own groove depth direction (e.g., Figure 2 The first dimension is located in the Y direction and is adapted to the dimension in the first direction of the inserted shaft segment 3512.

[0171] The second groove 3523 is in a second direction perpendicular to its own groove depth direction (e.g., Figure 2 The first dimension has a second dimension in the Y direction, which is adapted to the dimension in the second direction of the massage drive shaft 2, and the second dimension is larger than the second dimension.

[0172] This configuration, through the eccentric wheel 352, helps to increase the power of the massage drive shaft 2 to transmit to the inclined shaft wheel 351, and further facilitates the massage drive shaft 2 to drive the inclined shaft wheel 351 to rotate.

[0173] For the massage transmission structure 35, further, such as Figure 2 and Figure 4 As shown, the massage transmission structure 35 also includes a support wheel 353, which is located on the side of the inclined shaft wheel 351 away from the eccentric wheel 352, and the support wheel 353 is connected to the inclined shaft section 3511.

[0174] like Figure 4 As shown, the first massage rod 341 is rotatably connected to the inclined shaft section 3511. The inclined shaft wheel 351 also includes a stop part 3514 connected to the inclined shaft section 3511. The stop part 3514 and the support wheel 353 are respectively placed on both sides of the first massage rod 341 in the axial direction of the inclined shaft section 3511. The stop part 3514 and the support wheel 353 are used to stop and cooperate with the first massage rod 341 in the axial direction of the inclined shaft section 3511.

[0175] With this configuration, the first massage rod 341 is stopped in the axial direction of the inclined shaft section 3511 by the stop part 3514 and the support wheel 353, which can prevent the first massage rod 341 from being excessively displaced in the axial direction of the inclined shaft section 3511 during operation. This helps to ensure the stability of the first massage rod 341 in this direction, and in turn helps to ensure the stability and accuracy of the massage action of the first massage head 311.

[0176] Furthermore, such as Figure 2 and Figure 4 As shown, the adjusting transmission component 6, the support wheel 353, and the inclined shaft wheel 351 are engaged in the upper limit of the axial direction of the massage drive shaft 2.

[0177] With this configuration, the limiting cooperation between the support wheel 353 and the inclined shaft wheel 351 and the adjusting transmission component 6 can increase the area of ​​the limiting cooperation between the adjusting transmission component 6 and the massage transmission structure 35, thereby enhancing the stability of the limiting cooperation between the adjusting transmission component 6 and the massage transmission structure 35, which is beneficial for precise control of the movement of the massage head 31.

[0178] In other embodiments, the adjusting transmission member 6 may only engage with the support wheel 353 or the inclined shaft wheel 351 along the axial direction of the massage drive shaft 2. Alternatively, the adjusting transmission member 6 may also engage with other structures in the massage transmission structure 35 that can move along the axial direction of the massage drive shaft 2. The engagement between the adjusting transmission member 6 and the massage transmission structure 35 is flexible and can be determined based on the actual structural design of the massage transmission structure 35.

[0179] Furthermore, such as Figure 2 As shown, a first limiting surface 3531 is provided on the support wheel 353, and a second limiting surface 3515 is provided on the inclined shaft wheel 351. The first limiting surface 3531 and the second limiting surface 3515 are spaced apart and opposite to each other in the axial direction of the massage drive shaft 2. The adjusting transmission component 6 is engaged with the first limiting surface 3531 and the second limiting surface 3515 in the axial direction of the massage drive shaft 2.

[0180] With this configuration, on the one hand, the support wheel 353 and the inclined shaft wheel 351 are limited to the adjustment transmission component 6 through the limiting surface, which ensures that both the support wheel 353 and the inclined shaft wheel 351 have a large limiting contact area with the adjustment transmission component 6, thereby ensuring the stability of the limiting contact between the support wheel 353 and the inclined shaft wheel 351 and the adjustment transmission component 6.

[0181] On the other hand, since there are two opposing limiting surfaces that cooperate with the adjusting transmission component 6, the first limiting surface 3531 and the second limiting surface 3515 can work together to block and restrict the axial force on the adjusting transmission component 6, regardless of which direction the adjusting transmission component 6 is subjected to, thus preventing the adjusting transmission component 6 from tilting or shifting due to uneven force, thereby ensuring the stability of the limiting effect.

[0182] Furthermore, both the first limiting surface 3531 and the second limiting surface 3515 are annular limiting surfaces arranged around the central axis of the massage drive shaft 2.

[0183] This configuration increases the area of ​​the limiting engagement between the adjusting transmission component 6 and the first limiting surface 3531 and the second limiting surface 3515, thereby further enhancing the stability and reliability of the limiting engagement between the adjusting transmission component 6 and the massage transmission structure 35.

[0184] like Figure 2As shown, at least one of the support wheel 353 and the inclined shaft wheel 351 is provided with a rotating mating surface 354. The rotating mating surface 354 is arranged around the central axis of the massage drive shaft 2 and is parallel to the central axis of the massage drive shaft 2. The rotating mating surface 354 rotates and engages with the adjusting transmission member 6 in the circumferential direction of the massage drive shaft 2.

[0185] This configuration, through the rotational engagement of the rotating mating surface 354 and the adjusting transmission component 6, helps to enhance the stability of the massage transmission structure 35 as it rotates with the massage drive shaft 2, thereby enhancing the stability of the massage head 31's movement and improving the comfort of the massage.

[0186] In a preferred embodiment, such as Figure 2 As shown, both the support wheel 353 and the inclined shaft wheel 351 are provided with rotating mating surfaces 354. This arrangement allows the adjusting transmission component 6 to rotate and engage with the rotating mating surfaces 354 on both the support wheel 353 and the inclined shaft wheel 351, which helps to further enhance the stability of the massage transmission structure 35 as it rotates with the massage drive shaft 2, thereby further enhancing the stability of the massage head 31's movement and improving massage comfort.

[0187] like Figure 1 As shown, the massage mechanism also includes a first gear transmission assembly 8, and the massage drive component 1 is connected to the massage drive shaft 2 via the first gear transmission assembly 8.

[0188] This configuration has two advantages. First, because gear transmission can maintain a stable transmission ratio, the massage drive component 1 is connected to the massage drive shaft 2 via the first gear transmission assembly 8, ensuring the motion accuracy and operational stability of the massage mechanism. Second, because gear transmission has a relatively long lifespan, the first gear transmission assembly 8 helps extend the lifespan of the transmission between the massage drive component 1 and the massage drive shaft 2, thereby extending the service life of the massage mechanism.

[0189] like Figure 1 As shown, the spacing adjustment mechanism also includes a second gear transmission assembly 9, and the spacing adjustment drive 4 is connected to the spacing adjustment shaft 5 via the second gear transmission assembly 9.

[0190] This configuration has two advantages. First, because gear transmission can maintain a stable transmission ratio, the pitch adjustment drive 4 is connected to the pitch adjustment shaft 5 via the second gear transmission assembly 9, ensuring the motion accuracy and operational stability of the pitch adjustment mechanism. Second, because gear transmission has a relatively long lifespan, the second gear transmission assembly 9 helps extend the lifespan of the transmission between the pitch adjustment drive 4 and the pitch adjustment shaft 5, thereby extending the service life of the pitch adjustment mechanism.

[0191] In this embodiment, both the first gear transmission assembly 8 and the second gear transmission assembly 9 are composed of multiple transmission gears. The structural configuration of the first gear transmission assembly 8 and the second gear transmission assembly 9 is relatively flexible.
