Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and in particular to a massage mechanism and massage equipment. Background Technology

[0002] As people's demands for quality of life increase, massage devices are appearing more and more widely in people's lives, and people are using massage devices to improve their quality of life.

[0003] In related technologies, massage devices typically include a first massage component, a massage drive, and a massage component. The massage drive drives the first massage component to move, thereby massaging the body parts to be massaged. However, the massage comfort level is usually not ideal when using massage devices in related technologies. Summary of the Invention

[0004] This application discloses a massage mechanism and massage device that can improve massage comfort while reducing the size of the massage mechanism.

[0005] To achieve the above objectives, firstly, this application discloses a massage mechanism, comprising:

[0006] chassis;

[0007] Mounting shaft, which is rotatably mounted on the housing;

[0008] A massage mechanism, comprising a first massage component, a second massage component, and a massage drive component, wherein the first and second massage components are sleeved on a mounting shaft and spaced apart along the axial direction of the mounting shaft, and the massage drive component is used to drive the first and / or second massage components to move.

[0009] A spacing adjustment mechanism, comprising an adjustment drive configured to drive the mounting shaft to rotate in order to adjust the spacing between the first massage assembly and the second massage assembly.

[0010] By setting a spacing adjustment mechanism and having the adjustment drive of the spacing adjustment mechanism drive the mounting shaft to rotate, the spacing between the first massage component and the second massage component can be adjusted. When the spacing between the first massage component and the second massage component is inappropriate, causing the first massage component and the second massage component to not fit well with the area to be massaged, the adjustment drive can drive the mounting shaft to rotate to adjust the spacing between the first massage component and the second massage component until the spacing between the first massage component and the second massage component can fit well with the area to be massaged, thereby greatly improving the massage comfort and making the massage comfort ideal.

[0011] Since the first and second massage components are fitted onto the mounting shaft, the massage drive can perform massage by driving the first and / or second massage components to move. The adjustment drive can adjust the distance between the first and second massage components by driving the mounting shaft to rotate. Therefore, the same mounting shaft can be used to fit both the first and second massage components, providing a structural guarantee for subsequent massage by adjusting the drive to move the first and / or second massage components. Simultaneously, the distance between the first and second massage components can also be adjusted by driving the mounting shaft to rotate, providing a structural guarantee for adjusting the distance between the first and second massage components.

[0012] In layman's terms, the same mounting shaft can provide structural support for the movement of the first massage component and / or the second massage component, as well as for adjusting the distance between the first and second massage components. In this way, there is no need to set up a separate mounting shaft specifically for adjusting the distance between the first and second massage components, thereby saving the number of mounting shafts, simplifying the structure of the massage mechanism, and reducing the size of the massage mechanism.

[0013] In one possible implementation, the spacing adjustment mechanism further includes:

[0014] A first adjusting member is sleeved on the mounting shaft and movably disposed on the housing along the axial direction of the mounting shaft. The first massage component is at least partially sleeved on the first adjusting member and is rotatably connected to the first adjusting member.

[0015] Since the first massage component is at least partially fitted onto the first adjusting member and rotatably connected to the first adjusting member about the axis of the mounting shaft, when the first adjusting member drives the first massage component to move axially along the mounting shaft, the first massage component can also rotate about the axis of the mounting shaft. This ensures that the axial movement of the first massage component along the mounting shaft and its rotation about the mounting shaft do not interfere with each other. This provides a structural guarantee that, during the subsequent adjustment of the distance between the first massage component and the second massage component, the first massage component can still rotate about the mounting shaft to perform massage. This allows the adjustment of the distance between the first and second massage components and the massage action to be performed simultaneously, thereby improving the user experience of the massage mechanism to a certain extent.

[0016] In one possible implementation, the mounting shaft is provided with a first external thread, and the first adjusting member is provided with a first internal thread that matches the first external thread, the first internal thread being threadedly connected to the first external thread.

[0017] Because the first internal thread on the first adjusting member is connected to the first external thread of the mounting shaft, and because the first adjusting member is movably mounted on the housing along the axial direction of the mounting shaft, when the adjusting drive member drives the mounting shaft to rotate, the rotational motion of the mounting shaft can be converted into the axial movement of the first adjusting member along the mounting shaft by the action of the first internal and first external threads. This achieves the purpose of moving the first massage assembly relative to the second massage assembly along the axial direction of the mounting shaft. The structural design is ingenious and can reduce the cost of the massage mechanism.

[0018] In one possible implementation, the first adjusting element includes:

[0019] A threaded sleeve, the threaded sleeve being fitted onto the mounting shaft, the threaded sleeve having the first internal thread, the first massage component being at least partially fitted onto the threaded sleeve and rotatably connected to the threaded sleeve; and...

[0020] A positioning rod is detachably sleeved on the outer peripheral wall of the threaded sleeve and is movably disposed on the housing along the axial direction of the mounting shaft.

[0021] Since the positioning rod is detachably sleeved on the outer peripheral wall of the threaded sleeve, in one possible assembly method when assembling the first adjusting component to the massage mechanism, the threaded sleeve and the positioning rod can be disassembled first, and then the positioning rod can be movably set on the housing along the axial direction of the mounting shaft. The threaded sleeve can be rotatably connected to the first massage component around the axis of the mounting shaft, and finally the positioning rod can be sleeved on the threaded sleeve. This assembly process can reduce the assembly difficulty of assembling the first adjusting component to the massage mechanism to a certain extent.

[0022] In one possible implementation, the first adjusting element further includes:

[0023] A bearing is fitted onto the threaded sleeve, and the first massage component is at least partially fitted onto the bearing.

[0024] Because bearings are technologically mature and inexpensive, when the first massage component is rotatably connected to the threaded sleeve via the bearing around the axis of the mounting shaft, the rotational reliability of the first massage component can be guaranteed while reducing the cost of the entire massage mechanism.

[0025] In one possible implementation, the first massage component includes:

[0026] The first movable component is slidably sleeved on the mounting shaft and rotatably connected to the first adjusting component;

[0027] The first massage head; and,

[0028] A first swing arm is disposed on the first movable member, and a first massage head is connected to the first swing arm.

[0029] By allowing the first movable member to be slidably fitted onto the mounting shaft along the axial direction of the mounting shaft, and to be rotatably connected to the first adjusting member around the axis of the mounting shaft, the action of adjusting the distance between the first massage head and the second massage component and the action of moving the first massage head to perform massage can be carried out simultaneously, without having to wait for the distance between the first massage head and the second massage component to be adjusted to a suitable distance before performing the massage action. Therefore, the user experience of the massage mechanism can be improved to a certain extent.

[0030] In one possible implementation, the housing is provided with a clearance hole, the shape and size of which match the movement trajectory of the first swing arm.

[0031] By setting a clearance hole, the clearance hole can guide the movement of the first swing arm, allowing the first swing arm to swing along the clearance hole in a plane parallel to the axis of the mounting shaft, thereby preventing the first swing arm from rotating with the eccentric wheel.

[0032] In one possible implementation, the first active element includes:

[0033] A slanted wheel, the slanted wheel having a blocking portion;

[0034] A pressure cap is detachably disposed on the inclined shaft wheel, and the first swing arm is sleeved on the inclined shaft wheel and limited between the blocking part and the pressure cap.

[0035] When the first moving part includes the inclined shaft wheel, the rotational motion of the inclined shaft wheel can be cleverly transformed into the oscillating motion of the first massage head in a plane parallel to the axis of the mounting shaft. Complex functions can be accomplished with a simple structure. The structural design is very ingenious and can reduce the cost of the massage mechanism to a certain extent.

[0036] By making the inclined shaft wheel have a blocking part and placing the first swing arm between the pressure cover and the blocking part, the first swing arm can be stably fitted on the peripheral wall of the inclined shaft wheel, thereby preventing the first swing arm from slipping off the peripheral wall of the inclined shaft wheel.

[0037] By making the pressure cap detachably connected to the slant wheel, it becomes easier and faster to rotatably mount the first swing arm around the axis of the slant wheel onto the circumferential wall of the slant wheel.

[0038] In one possible implementation, the pressure cap is fitted onto the first adjusting member and is rotatably connected to the first adjusting member.

[0039] By rotatably connecting the pressure cap to the first adjusting member around the axis of the mounting shaft, the assembly of the first adjusting member and the first massage assembly can be made very flexible, thereby reducing the difficulty of assembling the first adjusting member and the first massage assembly to a certain extent.

[0040] In one possible implementation, the massage facility also includes:

[0041] A third massage component, wherein the third massage component is sleeved on the mounting shaft; and...

[0042] A fourth massage component is sleeved on the mounting shaft, and the massage drive is also used to drive the third massage component and / or the fourth massage component to move.

[0043] By setting up a third and fourth massage component, in addition to the massage provided by the first and second massage components, massage can also be provided by the third and fourth massage components, thereby improving the massage effect of the massage mechanism.

[0044] In one possible implementation, the fourth massage component and the third massage component are located axially between the first massage component and the second massage component along the mounting shaft.

[0045] By positioning the fourth and third massage components along the mounting axis between the first and second massage components, the fourth and third massage components can be arranged relatively centrally, while the first and second massage components can be arranged relatively dispersedly. In this way, areas requiring concentrated massage can be massaged using the fourth and third massage components, while areas requiring dispersed massage can be massaged using the first and second massage components. This broadens the applicability of the massage mechanism.

[0046] In one possible implementation, the third massage component includes:

[0047] A first eccentric member, rotatably sleeved on the mounting shaft, is drively connected to the massage drive member and configured to perform eccentric motion about the mounting shaft under the drive of the massage drive member; and,

[0048] The third massage head is disposed on the first eccentric member.

[0049] By setting a first eccentric component and driving the first eccentric component to move eccentrically around the axis of the mounting shaft through a massage drive component, when the third massage head is connected to the first eccentric component, the eccentric movement of the first eccentric component can be converted into the movement of the third massage head, thereby achieving the purpose of percussion massage through the third massage head. The structural design is very ingenious.

[0050] In one possible implementation, the first eccentric member is sleeved with the first rotating member, the first movable member is at least partially sleeved with the first rotating member for anti-rotation connection, and is slidably disposed on the first rotating member along the axial direction of the mounting shaft, and the first eccentric member drives the first rotating member to rotate around the mounting shaft when it moves eccentrically.

[0051] By fitting the first eccentric member and the first rotating member together, the movement of the first eccentric member can be transmitted to the first movable member through the first rotating member, thereby achieving the purpose of kneading and massaging through the first massage head.

[0052] By configuring the first eccentric component and the first rotating component together, when the first eccentric component moves, it can not only drive the third massage head to move for a percussive massage, but also drive the first massage head to move for a kneading massage. This configuration allows the movements of the third and first massage heads to be synchronized, enabling both to target different areas simultaneously for a more effective massage.

[0053] In one possible implementation, the first rotating member includes:

[0054] The socket portion is eccentrically fitted onto the first eccentric member; and,

[0055] The first movable member has an anti-rotation part, and an anti-rotation hole that matches the anti-rotation part is provided on the first movable member. The first movable member is sleeved on the anti-rotation part through the anti-rotation hole.

[0056] By cooperating with the anti-rotation part and the anti-rotation hole, the purpose of connecting the first moving part around the axis of the mounting shaft with the first rotating part to prevent rotation can be achieved. The structure is simple, and therefore, the cost of the massage mechanism can be reduced to a certain extent.

[0057] In one possible implementation, the first eccentric element includes:

[0058] A first gear disc, sleeved on and coaxial with the mounting shaft, is used by the massage drive to drive the first gear disc to rotate about the mounting shaft; and...

[0059] The first eccentric disc is eccentrically disposed on the first gear disc, and the axis of the first eccentric disc is parallel to the axis of the first gear disc. The third massage head is connected to the first eccentric disc in a transmission manner.

[0060] By eccentrically positioning the first eccentric disk on the first gear disk and making the axis of the first eccentric disk parallel to the axis of the first gear disk, when the first gear disk rotates around the axis of the mounting shaft, the rotational motion of the first gear disk around the axis of the mounting shaft can be converted into the eccentric motion of the first eccentric disk. In this way, even if both the first eccentric disk and the first gear disk are disc structures, the first eccentric disk can still complete the eccentric motion.

[0061] It is understandable that when both the first eccentric disk and the first gear disk are circular structures, compared to elliptical disks or other shapes that can achieve eccentric motion, on the one hand, it facilitates the connection of the first gear disk with other structures, providing a structural guarantee for the subsequent massage drive to drive the first gear disk to rotate; on the other hand, it can also simplify the structure of the entire first eccentric component and reduce its cost.

[0062] In one possible implementation, the third massage component further includes:

[0063] A first connecting arm is rotatably disposed on the first eccentric disk about the axis of the first eccentric disk.

[0064] A first massage arm is hinged to the housing about a first axis parallel to the mounting shaft axis. A third massage head is connected to the first massage arm. A first connecting arm is connected to the first massage arm.

[0065] With this setup, the movement trajectory and direction of the first massage head are completely different from those of the third massage head during massage. This allows the massage mechanism to massage the area to be massaged from various angles and directions, resulting in a better massage effect.

[0066] In one possible implementation, the fourth massage component includes:

[0067] A second eccentric member, rotatably sleeved on the mounting shaft, is drively connected to the massage drive member and configured to perform eccentric motion about the axis of the mounting shaft under the drive of the massage drive member; and,

[0068] A fourth massage head is disposed on the second eccentric member.

[0069] In one possible implementation, the second eccentric element includes:

[0070] A second gear disc, sleeved on and coaxial with the mounting shaft, is further configured to drive the second gear disc to rotate about the mounting shaft; and...

[0071] The second eccentric disc is eccentrically disposed on the second gear disc, the axis of the second eccentric disc is parallel to the axis of the second gear disc, the second eccentric disc is disposed opposite to the first eccentric disc, and the fourth massage head is connected to the second eccentric disc in a transmission manner.

[0072] In one possible implementation, the spacing adjustment mechanism further includes:

[0073] An adjusting gear is sleeved on the mounting shaft and located between the first gear disk and the second gear disk along the axial direction of the mounting shaft. The adjusting drive is used to drive the adjusting gear to rotate, thereby driving the mounting shaft to rotate.

[0074] By positioning the adjusting gear between the first and second gear discs, the space between the two gear discs can be fully utilized, making the entire massage mechanism more compact and smaller in size.

[0075] In one possible implementation, the massage mechanism further includes:

[0076] A transmission assembly is connected to the second gear disk and the first gear disk respectively. The massage drive is connected to the transmission assembly and is used to synchronously drive the first gear disk and the second gear disk to rotate around the mounting shaft through the transmission assembly.

[0077] By setting up a transmission component, the movement of the massage drive can be synchronously transmitted to the second gear plate and the first gear plate, thereby synchronously driving the first massage component, the second massage component, the third massage component and the fourth massage component to move. There is no need to set up separate massage drive components for the first massage component, the second massage component, the third massage component and the fourth massage component. Therefore, on the one hand, the number of massage drive components can be reduced, the cost of the massage mechanism can be reduced, and on the other hand, the structure of the massage mechanism can be made more compact and the size smaller.

[0078] In one possible implementation, the transmission assembly includes:

[0079] A drive shaft, which is rotatably mounted on the housing;

[0080] A first driving gear, which is sleeved on the drive shaft and meshes with the first gear disc; and

[0081] The second driving gear is sleeved on the transmission shaft and meshes with the second gear disk.

[0082] When the transmission assembly includes a transmission shaft, a first drive gear, and a second drive gear, the action of the massage drive component can be transmitted to the first and second gear disks through the meshing between the first drive gear and the first gear disk, and the meshing between the second drive gear and the second gear disk. The implementation method is very simple and can reduce the cost of the transmission assembly to a certain extent.

[0083] In one possible implementation, the number of teeth of the first drive gear is less than the number of teeth of the first gear disk.

[0084] By making the number of teeth of the first driving gear smaller than the number of teeth of the first gear disk, a smaller model of massage drive component can be selected to achieve the purpose of synchronously driving the rotation of the first gear disk and the second gear disk. In this way, on the one hand, the cost of the massage drive component can be reduced, and on the other hand, the volume occupied by the massage drive component can be reduced, thereby making the overall massage mechanism smaller.

[0085] In one possible implementation, the transmission assembly further includes:

[0086] The third driving gear is sleeved on the drive shaft and located between the first and second driving gears. The third driving gear is connected to both the massage drive component and the drive shaft. By aligning the third driving gear on the drive shaft and positioning it axially between the first and second driving gears, the space between them can be fully utilized, resulting in a more compact massage mechanism. Furthermore, the arrangement of the first, third, and second driving gears on the drive shaft is more balanced, leading to more balanced force distribution.

[0087] In one possible implementation, the spacing adjustment mechanism further includes:

[0088] The second adjusting member is sleeved on the mounting shaft and movably disposed on the housing along the axial direction of the mounting shaft. The second massage component is at least partially sleeved on the second adjusting member and is rotatably connected to the second adjusting member.

[0089] In one possible implementation, the mounting shaft is provided with a second external thread, and the second adjusting member is provided with a second internal thread that matches the second external thread, the second internal thread being threadedly connected to the second external thread.

[0090] In one possible implementation, the second external thread and the first external thread are located at opposite ends of the mounting shaft.

[0091] By positioning the second external thread and the first external thread at opposite ends of the mounting shaft, space can be left in the middle of the mounting shaft to accommodate other components, thereby making the structural layout of the massage mechanism more reasonable and the structure more compact to a certain extent.

[0092] On the other hand, when adjusting the distance between the first massage component and the second massage component, the force that causes the first and second massage components to move along the axial direction of the mounting shaft can be mainly derived from both ends of the mounting shaft. In this way, the force on the mounting shaft can be more dispersed, thereby avoiding the possibility of bending and deformation of the mounting shaft due to excessive force concentration.

[0093] In one possible implementation, the thread direction of the second external thread is opposite to that of the first external thread.

[0094] By making the thread direction of the second external thread opposite to that of the first external thread, the first and second massage components can move closer or further apart synchronously when the mounting shaft rotates around its own axis. This greatly improves the adjustment efficiency when adjusting the distance between the first and second massage components.

[0095] In one possible implementation, the second massage component includes:

[0096] The second movable component is slidably sleeved on the mounting shaft and rotatably connected to the second adjusting component;

[0097] The second massage head; and,

[0098] The second swing arm is disposed on the second movable member, and the second massage head is connected to the second swing arm.

[0099] In one possible implementation, the massage mechanism further includes:

[0100] A third massage component, wherein the third massage component is sleeved on the mounting shaft; and...

[0101] The fourth massage component is sleeved on the mounting shaft, and the massage drive is also used to drive the third massage component and / or the fourth massage component to move;

[0102] The third massage component is sleeved on the first movable member, and / or the fourth massage component is sleeved on the second movable member.

[0103] Since the third massage component is fitted onto the first movable component and the fourth massage component is fitted onto the second movable component, when the first and second movable components move along the axial direction of the mounting shaft, they can drive the third and fourth massage components to move along the axial direction of the mounting shaft. This allows the distance between the third and fourth massage components to be adjusted, thereby making the massage mechanism more functional and more adaptable.

[0104] Secondly, this application discloses a massage device, including the massage mechanism described in any of the first aspects above.

[0105] Because massage mechanisms offer ideal massage comfort and are relatively compact, their application in massage devices can enhance the user experience while reducing the device's size.

[0106] Compared with the prior art, the beneficial effects of this application are as follows:

[0107] In this application, by setting a spacing adjustment mechanism and causing the adjustment drive of the spacing adjustment mechanism to drive the mounting shaft to rotate to adjust the spacing between the first massage component and the second massage component, when the spacing between the first massage component and the second massage component is inappropriate, causing the first massage component and the second massage component to not fit well with the area to be massaged, the adjustment drive can drive the mounting shaft to rotate to adjust the spacing between the first massage component and the second massage component until the spacing between the first massage component and the second massage component can fit well with the area to be massaged, thereby greatly improving the massage comfort and making the massage comfort ideal.

[0108] Since the first and second massage components are fitted onto the mounting shaft, the massage drive can perform massage by driving the first and / or second massage components to move. The adjustment drive can adjust the distance between the first and second massage components by driving the mounting shaft to rotate. Therefore, the same mounting shaft can be used to fit both the first and second massage components, providing a structural guarantee for subsequent massage by adjusting the drive to move the first and / or second massage components. Simultaneously, the distance between the first and second massage components can also be adjusted by driving the mounting shaft to rotate, providing a structural guarantee for adjusting the distance between the first and second massage components.

[0109] In layman's terms, the same mounting shaft can provide structural support for the movement of the first massage component and / or the second massage component, as well as for adjusting the distance between the first and second massage components. In this way, there is no need to set up a separate mounting shaft specifically for adjusting the distance between the first and second massage components, thereby saving the number of mounting shafts, simplifying the structure of the massage mechanism, and reducing the size of the massage mechanism.

The mounting shaft 2 is rotatably mounted on the housing 1. (See attached image.) Figure 3 , Figure 4 and Figure 5 The massage mechanism 3 includes a first massage component 31, a second massage component 32, and a massage drive component 33. The first massage component 31 and the second massage component 32 are sleeved on the mounting shaft 2 and are aligned along the axial direction of the mounting shaft 2. Figure 4The massage drive 33 is used to drive the first massage component 31 and / or the second massage component 32 to move in the Y-axis direction. The spacing adjustment mechanism 4 includes an adjustment drive 41, which is configured to drive the mounting shaft 2 to rotate to adjust the spacing between the first massage component 31 and the second massage component 32.

[0149] In this embodiment, when massaging through the massage mechanism 100, the first massage component 31 and / or the second massage component 32 can be driven to move by the massage drive 33. When the first massage component 31 and / or the second massage component 32 move, the first massage component 31 and / or the second massage component 32 can knead, pound or other forms of massage on the part of the body to be massaged, thereby achieving the purpose of relaxing the part to be massaged.

[0150] However, when the spacing between the first massage component 31 and the second massage component 32 is inappropriate, causing the first massage component 31 and the second massage component 32 to not fit well with the area to be massaged, the first massage component 31 and the second massage component 32 will not be able to perform massage in the appropriate position, which will greatly reduce the massage comfort and make the massage comfort less than ideal.

[0151] In view of this, the massage mechanism 100 is equipped with a spacing adjustment mechanism 4, and the adjustment drive 41 of the spacing adjustment mechanism 4 drives the mounting shaft 2 to rotate to adjust the spacing between the first massage component 31 and the second massage component 32. This allows the adjustment drive 41 to adjust the spacing between the first massage component 31 and the second massage component 32 by driving the mounting shaft 2 to rotate when the spacing between the first massage component 31 and the second massage component 32 is inappropriate, causing the first massage component 31 and the second massage component 32 to not fit well with the area to be massaged. This adjustment is made until the spacing between the first massage component 31 and the second massage component 32 can fit well with the area to be massaged, thereby greatly improving the massage comfort and making the massage comfort ideal.

[0152] Since the first massage component 31 and the second massage component 32 are fitted onto the mounting shaft 2, the massage drive 33 can perform massage by driving the first massage component 31 and / or the second massage component 32 to move. The adjustment drive 41 can adjust the distance between the first massage component 31 and the second massage component 32 by driving the mounting shaft 2 to rotate. Therefore, the same mounting shaft 2 can be used to fit the first massage component 31 and the second massage component 32, providing a structural guarantee for subsequent massage by driving the first massage component 31 and / or the second massage component 32 to move via the adjustment drive 41. At the same time, the distance between the first massage component 31 and the second massage component 32 can also be adjusted by driving the mounting shaft 2 to rotate, providing a structural guarantee for adjusting the distance between the first massage component 31 and the second massage component 32.

[0153] In layman's terms, the same mounting shaft 2 can provide structural support for the movement of the first massage component 31 and / or the second massage component 32, and also provide structural support for adjusting the distance between the first massage component 31 and the second massage component 32. In this way, there is no need to set up a separate mounting shaft 2 specifically for adjusting the distance between the first massage component 31 and the second massage component 32, thereby saving the number of mounting shafts 2, simplifying the structure of the massage mechanism 100 and reducing the size of the massage mechanism 100.

[0154] It should be noted that, see Figure 2 and Figure 3 The aforementioned mounting shaft 2 can be rotatably mounted on the housing 1 via bearing 423, or it can be rotatably mounted on the housing 1 in other ways. This embodiment does not limit this.

[0155] In addition, the aforementioned adjustment drive 41 and massage drive 33 can be motors or other possible drive elements, and this embodiment does not limit them.

[0156] It should also be noted that the massage mechanism 100 described above can be used in shoulder and neck massagers, as well as waist massagers or leg massagers, etc., and this embodiment does not limit it in this regard. In addition, the massage mechanism 100 described above can be used not only to massage the parts of the human body to be massaged, but also to massage the parts of animals to be massaged, such as the parts of a cat or dog to be massaged, and this embodiment does not limit it in this regard either.

[0157] Taking the massage mechanism 100 applied to a neck and shoulder massager as an example, specifically, when the massage mechanism 100 is applied to a neck and shoulder massager, the area to be massaged is the neck. Therefore, when the user's neck size varies, causing the first massage component 31 and the second massage component 32 to no longer perfectly fit the changed user's neck, the adjusting drive component 41 adjusts the distance between the first massage component 31 and the second massage component 32 by driving the mounting shaft 2 to rotate. This ensures that the adjusted distance between the first massage component 31 and the second massage component 32 still perfectly fits the changed user's neck, thus obviously improving massage comfort and making the massage more comfortable.

[0158] In some embodiments, see Figure 2 and Figure 3 The spacing adjustment mechanism 4 further includes: a first adjusting member 42, which is sleeved on the mounting shaft 2 and movably disposed on the housing 1 along the axial direction of the mounting shaft 2; a first massage component 31 is at least partially sleeved on the first adjusting member 42, and the first massage component 31 is rotatably connected to the first adjusting member 42. The mounting shaft 2 is configured to drive the first adjusting member 42 to move along the axial direction of the mounting shaft 2 when rotated, thereby causing the first massage component 31 to move relative to the second massage component 32 along the axial direction of the mounting shaft 2.

[0159] Since the first adjusting member 42 is sleeved on the mounting shaft 2 and is movably disposed on the housing 1 along the axial direction of the mounting shaft 2, under the guiding action of the housing 1, when the mounting shaft 2 rotates, it can drive the first adjusting member 42 to move along the axial direction of the mounting shaft 2.

[0160] When the first adjusting member 42 moves along the axial direction of the mounting shaft 2, since the first massage component 31 is at least partially sleeved on the first adjusting member 42, the first adjusting member 42 can synchronously drive the first massage component 31 to move along the axial direction of the mounting shaft 2, thereby changing the distance between the first massage component 31 and the second massage component 32 along the axial direction of the mounting shaft 2, and thus achieving the purpose of adjusting the distance between the first massage component 31 and the second massage component 32.

[0161] Since the first massage component 31 is rotatably connected to the first adjusting member 42 around the mounting shaft 2, when the first adjusting member 42 drives the first massage component 31 to move axially along the mounting shaft 2, the first massage component 31 can also rotate around the axis of the mounting shaft 2. This ensures that the axial movement of the first massage component 31 along the mounting shaft 2 and its rotation around the axis of the mounting shaft 2 do not interfere with each other. This provides a structural guarantee that the first massage component 31 can still rotate around the axis of the mounting shaft 2 for massage during the subsequent adjustment of the distance between the first massage component 31 and the second massage component 32. This allows the adjustment of the distance between the first massage component 31 and the second massage component 32 to occur simultaneously with the massage action, thereby improving the user experience of the massage mechanism 100 to a certain extent.

[0162] In order to detect the change in the distance between the first massage component 31 and the second massage component 32, and to provide data support for subsequently adjusting the distance between the first massage component 31 and the second massage component 32 to a suitable distance, in some embodiments, see [link to relevant documentation]. Figure 2 and Figure 3 A position detection element 12 can be provided on the housing 1 to detect the position of the first adjustment member 42. In this way, the change in the position of the first adjustment member 42 can be detected to obtain the change in the distance between the first massage component 31 and the second massage component 32, thereby providing data support for adjusting the distance between the first massage component 31 and the second massage component 32 to a suitable distance, making the massage mechanism 100 more intelligent.

[0163] The position detection element 12 can be a sliding rheostat or other possible electronic components that can detect the position of the first adjusting member 42. This embodiment does not limit the position detection element 12.

[0164] In some embodiments, see Figure 3 and Figure 6 , Figure 6 yes Figure 3 The first adjusting member 42 is shown in the schematic diagram. The peripheral wall of the mounting shaft 2 is provided with a first external thread 2a, and the first adjusting member 42 is provided with a first internal thread 42a that matches the first external thread 2a. The first internal thread 42a is threadedly connected to the first external thread 2a.

[0165] Since the first internal thread 42a on the first adjusting member 42 is threaded to the first external thread 2a on the peripheral wall of the mounting shaft 2, and since the first adjusting member 42 is movably disposed on the housing 1 along the axial direction of the mounting shaft 2, when the adjusting drive member 41 drives the mounting shaft 2 to rotate, the rotational motion of the mounting shaft 2 can be converted into the axial movement of the first adjusting member 42 along the mounting shaft 2 under the action of the first internal thread 42a and the first external thread 2a. This achieves the purpose of moving the first massage assembly 31 relative to the second massage assembly 32 along the axial direction of the mounting shaft 2. The structural design is ingenious and can reduce the cost of the massage mechanism 100.

[0166] In some embodiments, please continue to see Figure 3 and Figure 6 The first adjusting component 42 includes a threaded sleeve 421 and a positioning rod 422. The threaded sleeve 421 is sleeved on the mounting shaft 2 and has a first internal thread 42a. The first massage component 31 is at least partially sleeved on the threaded sleeve 421 and rotatably connected to the threaded sleeve 421. The positioning rod 422 is detachably sleeved on the outer peripheral wall of the threaded sleeve 421 and is movably disposed on the housing 1 along the axial direction of the mounting shaft 2.

[0167] Since the positioning rod 422 is detachably sleeved on the outer peripheral wall of the threaded sleeve 421, when assembling the first adjusting component 42 to the massage mechanism 100, in one possible assembly method, the threaded sleeve 421 and the positioning rod 422 can be first separated, and then the positioning rod 422 can be movably set on the housing 1 along the axial direction of the mounting shaft 2. The threaded sleeve 421 can be rotatably connected to the first massage component 31 around the axis of the mounting shaft 2. Finally, the positioning rod 422 can be sleeved on the threaded sleeve 421. This assembly step can reduce the assembly difficulty of assembling the first adjusting component 42 to the massage mechanism 100 to a certain extent.

[0168] Of course, in another possible assembly method, the threaded sleeve 421 and the positioning rod 422 can be assembled first, and then the positioning rod 422 can be movably set on the housing 1 along the axial direction of the mounting shaft 2, and the threaded sleeve 421 can be rotatably connected to the first massage component 31 around the axis of the mounting shaft 2.

[0169] As can be seen, by making the first adjusting member 42 include a threaded sleeve 421 and a positioning rod 422, and making the positioning rod 422 detachably sleeved on the outer peripheral wall of the threaded sleeve 421, when assembling the first adjusting member 42 to the massage mechanism 100, the assembly method can be flexibly selected according to the situation, thus reducing the possibility of assembly difficulties or inability to assemble to a certain extent.

[0170] By setting the positioning rod 422, on the one hand, since the positioning rod 422 is movably set on the housing 1 along the axial direction of the mounting shaft 2, the positioning rod 422 can guide the threaded sleeve 421 to move along the axial direction of the mounting shaft 2. On the other hand, the positioning rod 422 can also provide wiring for the position detection element 12. Furthermore, the positioning rod 422 can also prevent the threaded sleeve 421 from rotating.

[0171] It should be noted that there are multiple ways in which the aforementioned positioning rod 422 can be detachably sleeved onto the outer peripheral wall of the threaded sleeve 421. For example, in one possible implementation, it can be as follows: Figure 6 The positioning rod 422 is detachably fitted onto the outer peripheral wall of the threaded sleeve 421 by means of a set screw. Of course, other means can also be used to achieve the purpose of detachably fitting the positioning rod 422 onto the outer peripheral wall of the threaded sleeve 421. This embodiment does not limit this.

[0172] It should also be noted that the aforementioned first massage component 31 and threaded sleeve 421 can be rotatably connected in various ways. In one possible implementation, see [link to relevant documentation]. Figure 3 , Figure 6 and Figure 7 , Figure 7 yes Figure 3 The first massage component 31 of the massage mechanism 100 is shown in the structural diagram after being removed from the mounting shaft 2. The first adjusting component 42 also includes a bearing 423, which is sleeved on the threaded sleeve 421. The first massage component 31 is at least partially sleeved on the bearing 423. That is, the first massage component 31 is rotatably connected to the threaded sleeve 421 around the axis of the mounting shaft 2 via the bearing 423.

[0173] Since the bearing 423 is technologically mature and inexpensive, when the first massage component 31 is rotatably connected to the threaded sleeve 421 around the axis of the mounting shaft 2 via the bearing 423, the rotational reliability of the first massage component 31 can be guaranteed while reducing the cost of the entire massage mechanism 100.

[0174] Of course, the first massage component 31 can also be rotatably connected to the threaded sleeve 421 around the axis of the mounting shaft 2 in other ways, and this embodiment does not limit this.

[0175] In some embodiments, see Figure 3 and Figure 7 The first massage assembly 31 includes: a first movable member 310 and a first massage head 312, wherein the first movable member 310 is along the axial direction of the mounting shaft 2. Figure 7The first massage head 312 is slidably sleeved on the mounting shaft 2 (in the Y-axis direction) and rotatably connected to the first adjusting member 42 around the mounting shaft 2. The first massage head 312 is disposed on the first movable member 310.

[0176] The massage drive 33 is used to drive the first movable member 310 to rotate around the axis of the mounting shaft 2, so as to drive the first massage head 312 to move. The first adjustment member 42 is used to drive the first movable member 310 to slide along the axial direction of the mounting shaft 2 when moving, so as to adjust the distance between the first massage head 312 and the second massage assembly 32.

[0177] In this embodiment, since the first massage head 312 is disposed on the first movable member 310, when the massage drive member 33 drives the first movable member 310 to rotate around the axis of the mounting shaft 2, it can drive the first massage head 312 to move, thereby achieving the purpose of massage through the first massage head 312.

[0178] In addition, since the first movable member 310 is slidably sleeved on the mounting shaft 2 along the axial direction of the mounting shaft 2 and connected to the first adjusting member 42, when the first adjusting member 42 moves along the axial direction of the mounting shaft 2, it can simultaneously drive the first movable member 310 to move along the axial direction of the mounting shaft 2, thereby achieving the purpose of adjusting the distance between the first massage head 312 and the second massage component 32.

[0179] As can be seen, by making the first movable member 310 slidably sleeved on the mounting shaft 2 along the axial direction of the mounting shaft 2, and rotatably connected to the first adjusting member 42 around the axis of the mounting shaft 2, the action of adjusting the distance between the first massage head 312 and the second massage component 32 and the action of moving the first massage head 312 to perform massage can be performed simultaneously, without having to wait for the distance between the first massage head 312 and the second massage component 32 to be adjusted to a suitable distance before performing the massage action. Therefore, the user experience of the massage mechanism 100 can be improved to a certain extent.

[0180] In some embodiments, see Figure 3 , Figure 7 and Figure 8 , Figure 8 yes Figure 7 An exploded view of the first massage component 31 shows that the first massage component 31 also includes a first swing arm 313, which is disposed on the first movable member 310. A first massage head 312 is connected to the first swing arm 313. The first movable member 310 includes a slanted wheel 311, and the first swing arm 313 is sleeved on the slanted wheel 311. (See also...) Figure 9 , Figure 9 yes Figure 3The massage mechanism 100 is shown in a structural schematic diagram from another perspective. The inclined shaft wheel 311 is configured to drive the first swing arm 313 to swing in a plane parallel to the axis of the mounting shaft 2 when it rotates about the axis of the mounting shaft 2.

[0181] Since the first massage head 312 is sleeved on the inclined shaft wheel 311 through the first swing arm 313, when the inclined shaft wheel 311 rotates around the axis of the mounting shaft 2, the rotation of the inclined shaft wheel 311 around the axis of the mounting shaft 2 can be converted into the swing of the first swing arm 313 in a plane parallel to the axis of the mounting shaft 2, which can then drive the first massage head 312 to swing in a plane parallel to the axis of the mounting shaft 2, thereby achieving the purpose of kneading massage through the first massage head 312.

[0182] That is, when the first movable part 310 includes the inclined shaft wheel 311, the rotational motion of the inclined shaft wheel 311 can be cleverly transformed into the oscillating motion of the first massage head 312 in a plane parallel to the axis of the mounting shaft 2. Complex functions can be accomplished with a simple structure. The structural design is very ingenious and can reduce the cost of the massage mechanism 100 to a certain extent.

[0183] In order to better convert the rotational motion of the inclined shaft wheel 311 into the oscillating motion of the first massage head 312, and to avoid the first swing arm 313 rotating with the inclined shaft wheel 311, in some embodiments, see [reference needed]. Figure 9 and Figure 10 , Figure 10 yes Figure 2 A schematic diagram of the structure of the massage mechanism 100 from another perspective (in Figure 2 Based on the above, some structures of the housing 1 are omitted. The housing 1 is provided with a clearance hole 11, and the shape and size of the clearance hole 11 match the movement trajectory of the first swing arm 313.

[0184] By setting the clearance hole 11, the clearance hole 11 can guide the movement of the first swing arm 313, so that the first swing arm 313 can swing along the clearance hole 11 in a plane parallel to the axis of the mounting shaft 2, thereby avoiding the situation where the first swing arm 313 rotates with the inclined shaft wheel 311.

[0185] Furthermore, to better ensure that the rotational motion of the inclined shaft wheel 311 can be converted into the oscillating motion of the first massage head 312, and to better avoid the situation where the first swing arm 313 follows the rotation of the inclined shaft wheel 311, in some embodiments, see... Figure 2 and Figure 8The first swing arm 313 is provided with a protrusion 3131, which is movably disposed on the housing 1 along the axis of the mounting shaft 2. This can better prevent the first swing arm 313 from rotating with the inclined shaft wheel 311, thereby better ensuring that the rotational motion of the inclined shaft wheel 311 can be converted into the swinging motion of the first massage head 312.

[0186] Since the first swing arm 313 is rotatably sleeved on the peripheral wall of the inclined shaft wheel 311 around the axis of the inclined shaft wheel 311, considering that the first swing arm 313 may slip off the peripheral wall of the inclined shaft wheel 311 during the rotation of the inclined shaft wheel 311 around the axis of the mounting shaft 2, which would cause the entire massage mechanism 100 to malfunction, in order to avoid this situation, see [reference to...] Figure 8 and Figure 11 , Figure 11 yes Figure 8 The diagram shows the structure of the first massage component 31 after disassembly. The inclined shaft wheel 311 has a blocking part 3111, which protrudes radially from the peripheral wall of the inclined shaft wheel 311. The first movable member 310 also includes a pressure cover 314, and the first swing arm 313 is located between the blocking part 3111 and the pressure cover 314.

[0187] By making the inclined shaft wheel 311 have a blocking part 3111 and making the first swing arm 313 located between the blocking part 3111 and the pressure cover 314, the first swing arm 313 can be stably sleeved on the peripheral wall of the inclined shaft wheel 311, thereby preventing the first swing arm 313 from slipping off the peripheral wall of the inclined shaft wheel 311.

[0188] To facilitate quick and easy assembly during the process of rotatably fitting the first swing arm 313 onto the peripheral wall of the inclined shaft wheel 311 around its axis, in some embodiments, see... Figure 8 and Figure 11 The pressure cap 314 is detachably mounted on the inclined shaft wheel 311.

[0189] By detachably connecting the pressure cap 314 to the inclined shaft wheel 311, during the process of rotatably fitting the first swing arm 313 around the axis of the inclined shaft wheel 311 onto the peripheral wall of the inclined shaft wheel 311, the pressure cap 314 can first be removed from the inclined shaft wheel 311, and then the first swing arm 313 can be rotatably fitted onto the peripheral wall of the inclined shaft wheel 311 around the axis of the inclined shaft wheel 311. After the first swing arm 313 is rotatably fitted onto the peripheral wall of the inclined shaft wheel 311 around the axis of the inclined shaft wheel 311, the pressure cap 314 can finally be connected to the inclined shaft wheel 311. In this way, the purpose of blocking the first swing arm 313 between the two blocking parts 3111 can be achieved.

[0190] Obviously, by making the pressure cap 314 detachably connected to the inclined shaft wheel 311, it becomes more convenient and faster to rotatably mount the first swing arm 313 around the axis of the inclined shaft wheel 311 onto the peripheral wall of the inclined shaft wheel 311.

[0191] The aforementioned pressure cap 314 can be detachably connected to the inclined shaft wheel 311 by screws or any other possible means, and this embodiment does not limit this.

[0192] In some embodiments, see Figure 3 and Figure 12 , Figure 12 yes Figure 3 The diagram shows the structure of the first massage component 31 and the first adjustment component 42. The pressure cover 314 is sleeved on the first adjustment component 42 and is rotatably connected to the first adjustment component 42.

[0193] Since the pressure cap 314 is detachably connected to the inclined shaft wheel 311, by making the pressure cap 314 rotatably connected to the first adjusting member 42 about the axis of the mounting shaft 2, the assembly sequence of assembling the first adjusting member 42 and the first massage assembly 31 can be selected as follows: first assembling the pressure cap 314 and the first adjusting member 42, and then assembling the pressure cap 314 and the inclined shaft wheel 311, or first assembling the pressure cap 314 and the inclined shaft wheel 311, and then assembling the pressure cap 314 and the first adjusting member 42.

[0194] It can be seen that by making the pressure cap 314 detachably connected to the inclined shaft wheel 311, the way the first adjusting member 42 and the first massage component 31 are assembled can be very flexible, thereby reducing the difficulty of assembling the first adjusting member 42 and the first massage component 31 to a certain extent.

[0195] In some embodiments, see Figure 4 The massage mechanism 3 also includes a third massage component 34 and a fourth massage component 35, wherein the third massage component 34 and the fourth massage component 35 are both mounted on the mounting shaft 2, and the massage drive component 33 is also used to drive the third massage component 34 and / or the fourth massage component 35 to move.

[0196] By setting the third massage component 34 and the fourth massage component 35, in addition to the massage that can be performed by the first massage component 31 and the second massage component 32, the massage can also be performed by the third massage component 34 and the fourth massage component 35, thereby making the massage effect of the massage mechanism 100 better.

[0197] In addition, since the third massage component 34 and the fourth massage component 35 are both mounted on the mounting shaft 2, in addition to the first massage component 31 and the second massage component 32 sharing the mounting shaft 2, the third massage component 34 and the fourth massage component 35 also share the mounting shaft 2, which can further reduce the number of mounting shafts 2, making the structure of the entire massage mechanism 100 more compact and small.

[0198] In addition, the massage drive 33 can drive the first massage component 31 and the second massage component 32 to move, as well as the third massage component 34 and / or the fourth massage component 35. In this way, the first massage component 31, the second massage component 32, the third massage component 34 and the fourth massage component 35 can share the same massage drive 33, thereby saving the number of massage drive components 33 and making the structure of the entire massage mechanism 100 more compact and small.

[0199] The first massage component 31, the second massage component 32, the third massage component 34, and the fourth massage component 35 can be arranged on the mounting shaft 2 in various ways. For one possible arrangement, please refer to [link to relevant documentation]. Figure 4 The fourth massage component 35 and the third massage component 34 are located between the first massage component 31 and the second massage component 32 along the axial direction of the mounting shaft 2.

[0200] By positioning the fourth massage component 35 and the third massage component 34 along the axial direction of the mounting shaft 2 between the first massage component 31 and the second massage component 32, the fourth massage component 35 and the third massage component 34 can be arranged relatively centrally, while the first massage component 31 and the second massage component 32 can be arranged relatively dispersedly. In this way, for some areas that need to be massaged in a concentrated manner, massage can be performed by the fourth massage component 35 and the third massage component 34, while for some areas that need to be massaged in a dispersed manner, massage can be performed by the first massage component 31 and the second massage component 32. This makes the massage mechanism 100 applicable to a wider range of scenarios.

[0201] In some embodiments, please continue to see Figure 4 The adjustment drive 41 is configured to drive the mounting shaft 2 to rotate in order to adjust the gap between the third massage assembly 34 and the fourth massage assembly 35.

[0202] Since the adjustment drive 41 can adjust the distance between the third massage component 34 and the fourth massage component 35 by rotating the drive mounting shaft 2, when the distance between the third massage component 34 and the fourth massage component 35 is inappropriate, causing the third massage component 34 and the fourth massage component 35 to not fit well with the area to be massaged, resulting in a poor massage effect, the adjustment drive 41 can adjust the distance between the third massage component 34 and the fourth massage component 35 by rotating the drive mounting shaft 2. This allows the distance between the third massage component 34 and the fourth massage component 35 to be adjusted to an appropriate distance, so that the third massage component 34 and the fourth massage component 35 can fit perfectly with the area to be massaged, making the massage effect ideal.

[0203] In addition, the adjustment drive 41, by driving the mounting shaft 2 to rotate, can not only adjust the distance between the first massage component 31 and the second massage component 32, but also adjust the distance between the third massage component 34 and the fourth massage component 35. That is, the same adjustment drive 41 can adjust the distance between the first massage component 31 and the second massage component 32, as well as the distance between the third massage component 34 and the fourth massage component 35. This reduces the number of adjustment drive 41s required, making the entire massage mechanism 100 more compact and smaller.

[0204] In some embodiments, see Figure 7 and Figure 13 , Figure 13 yes Figure 7 The diagram shows the structure of the third massage component 34. The third massage component 34 includes a first eccentric member 341 and a third massage head 342. The first eccentric member 341 is rotatably mounted on the mounting shaft 2. The first eccentric member 341 is connected to the massage drive member 33 and configured to perform eccentric motion around the mounting shaft 2 under the drive of the massage drive member 33. The third massage head 342 is disposed on the first eccentric member 341. When the first eccentric member 341 moves eccentrically around the axis of the mounting shaft 2, it drives the third massage head 342 to move.

[0205] Since the third massage head 342 is disposed on the first eccentric member 341, when the massage drive member 33 drives the first eccentric member 341 to move eccentrically around the axis of the mounting shaft 2, it can drive the third massage head 342 to move, thereby achieving the purpose of massage through the third massage head 342.

[0206] As can be seen, by setting the first eccentric member 341 and driving the first eccentric member 341 to move eccentrically around the axis of the mounting shaft 2 through the massage drive member 33, when the third massage head 342 is connected to the first eccentric member 341, the eccentric movement of the first eccentric member 341 can be converted into the movement of the third massage head 342, thereby achieving the purpose of percussion massage through the third massage head 342. The structural design is very ingenious.

[0207] In some embodiments, see Figure 7 and Figure 14 , Figure 14 yes Figure 3 A schematic diagram of the massage mechanism 100 from another perspective shows that the first eccentric member 341 and the first rotating member 3411 are sleeved together, and the first movable member 310 is at least partially sleeved with the first rotating member 3411 to prevent rotation, and is aligned along the axis of the mounting shaft 2. Figure 7 The first eccentric component 3411 is slidably disposed on the first rotating component 3411 in the Y-axis direction. When the first eccentric component 341 moves eccentrically, it drives the first rotating component 3411 to rotate around the mounting shaft 2.

[0208] Since the first eccentric member 341 and the first rotating member 3411 are sleeved together, when the first eccentric member 341 moves eccentrically, it can drive the first rotating member 3411 to rotate around the axis of the mounting shaft 2. When the first rotating member 3411 rotates around the axis of the mounting shaft 2, since the first movable member 310 is at least partially sleeved with the first rotating member 3411 to prevent rotation, the first rotating member 3411 can synchronously drive the first movable member 310 to rotate around the axis of the mounting shaft 2.

[0209] When the first movable member 310 rotates around the axis of the mounting shaft 2, the first movable member 310 can convert the rotational motion around the axis of the mounting shaft 2 into the swing motion of the first swing arm 313 in a plane parallel to the axis of the mounting shaft 2, which can then drive the first massage head 312 to swing in a plane parallel to the axis of the mounting shaft 2, thereby achieving the purpose of kneading massage through the first massage head 312.

[0210] In addition, since the first movable member 310 is slidably disposed on the first rotating member 3411 along the axial direction of the mounting shaft 2, when the first adjusting member 42 moves along the axial direction of the mounting shaft 2, it can simultaneously drive the first movable member 310 to slide relative to the first rotating member 3411 along the axial direction of the mounting shaft 2, thereby achieving the purpose of adjusting the distance between the first massage component 31 and the second massage component 32.

[0211] As can be seen, by setting the first rotating member 3411 on the first eccentric member 341, the movement of the first eccentric member 341 can be transmitted to the first movable member 310 through the first rotating member 3411, thereby achieving the purpose of kneading and massaging through the first massage head 312.

[0212] In other words, by setting a first rotating member 3411 on the first eccentric member 341, when the first eccentric member 341 moves, it can not only drive the third massage head 342 to move for percussion massage, but also drive the first massage head 312 to move for kneading massage. This arrangement allows the movements of the third massage head 342 and the first massage head 312 to move in tandem, thus enabling the third massage head 342 and the first massage head 312 to simultaneously target multiple areas for massage, resulting in a better massage effect.

[0213] The first movable member 310 can be connected to the first rotating member 3411 in a non-rotating manner around the axis of the mounting shaft 2 in several ways. In one possible implementation, see [link to relevant documentation]. Figure 7 and Figure 15 , Figure 15 yes Figure 7 The first massage component 31 is shown in a schematic diagram from another perspective. The first rotating member 3411 includes a sleeve portion 3411a and an anti-rotation portion 3411b. The sleeve portion 3411a is eccentrically fitted with the first eccentric member 341. The anti-rotation portion 3411b is disposed on the sleeve portion 3411a and extends along the axial direction of the mounting shaft 2. The first movable member 310 is provided with an anti-rotation hole 3112 that matches the anti-rotation portion 3411b. The first movable member 310 is slidably fitted onto the anti-rotation portion 3411b along the axial direction of the mounting shaft 2 through the anti-rotation hole 3112. The anti-rotation hole 3112 cooperates with the anti-rotation portion 3411b to prevent the first movable member 310 from rotating relative to the sleeve portion 3411a about the axis of the mounting shaft 2.

[0214] Since the anti-rotation part 3411b is provided on the sleeve part 3411a and extends along the axial direction of the mounting shaft 2, and since the first movable member 310 is provided with an anti-rotation hole 3112 that matches the anti-rotation part 3411b, when the first movable member 310 is slidably sleeved on the anti-rotation part 3411b along the axial direction of the mounting shaft 2 through the anti-rotation hole 3112, under the cooperation of the anti-rotation hole 3112 and the anti-rotation part 3411b, the first movable member 310 can only slide relative to the first rotating member 3411 along the axial direction of the mounting shaft 2 and cannot rotate relative to the first rotating member 3411 around the axis of the mounting shaft 2. In this way, on the one hand, it can be ensured that the rotational movement of the first eccentric member 341 can be transmitted to the first movable member 310 through the first rotating member 3411, so as to drive the first massage head 312 to swing to achieve the purpose of kneading massage. On the other hand, it can also ensure that when the first adjusting member 42 moves along the axial direction of the mounting shaft 2, it can simultaneously drive the first movable member 310 to slide relative to the first rotating member 3411 along the axial direction of the mounting shaft 2, thereby achieving the purpose of adjusting the distance between the first massage component 31 and the second massage component 32.

[0215] As can be seen, the purpose of preventing the first movable part 310 from rotating and connecting the first rotating part 3411 to the first rotating part 3411 around the axis of the mounting shaft 2 can be achieved through the cooperation between the anti-rotation part 3411b and the anti-rotation hole 3112. The structure is simple, and therefore, the cost of the massage mechanism 100 can be reduced to a certain extent.

[0216] Considering the fit between the anti-rotation part 3411b and the anti-rotation hole 3112, its main purpose is to achieve an anti-rotation connection between the first movable member 310 and the first rotating member 3411 around the axis of the mounting shaft 2. To achieve this purpose, see [reference needed]. Figure 15 The anti-rotation hole 3112 may have a stop edge 3112a on its wall. For example, when the cross-sectional shape of the anti-rotation hole 3112 is as follows... Figure 15 When the rectangle shown is used, its four edges are the aforementioned stop edges 3112a. In this way, when the anti-rotation part 3411b is inserted into the anti-rotation hole 3112, the anti-rotation part 3411b cannot rotate around the axis of the mounting shaft 2 within the anti-rotation hole 3112 due to the stopping action of the stop edges 3112a. This achieves the purpose of preventing the first movable member 310 from rotating around the axis of the mounting shaft 2 and connecting it to the first rotating member 3411.

[0217] The rectangular shape of the cross-section of the anti-rotation hole 3112 is only one possible implementation method given in this embodiment. Of course, the cross-section of the anti-rotation hole 3112 can also be other possible shapes, such as triangular or other regular or irregular shapes. This embodiment does not limit this.

[0218] In some embodiments, see Figure 7and Figure 13 The first eccentric component 341 includes a first gear disk 3412 and a first eccentric disk 3413. The first gear disk 3412 is rotatably sleeved on the mounting shaft 2 and coaxial with the mounting shaft 2. The massage drive component 33 is used to drive the first gear disk 3412 to rotate around the mounting shaft 2. The first eccentric disk 3413 is eccentrically disposed on the first gear disk 3412 and parallel to the axis of the first gear disk 3412. The third massage head 342 is connected to the first eccentric disk 3413 in a transmission connection. When the first eccentric disk 3413 moves eccentrically around the axis of the mounting shaft 2, it drives the third massage head 342 to move.

[0219] Since the first eccentric disk 3413 is eccentrically disposed on the first gear disk 3412 and the axis of the first gear disk 3412 is parallel to the axis of the first gear disk 3412, when the massage drive 33 drives the first gear disk 3412 to rotate around the axis of the mounting shaft 2, it can drive the first eccentric disk 3413 to perform eccentric motion.

[0220] Based on this, since the third massage head 342 is connected to the first eccentric disc 3413, when the first eccentric disc 3413 makes an eccentric movement, it can drive the third massage head 342 to move, thereby achieving the purpose of massage through the third massage head 342.

[0221] It can be seen that by setting the first eccentric disk 3413 on the first gear disk 3412 and making the axis of the first eccentric disk 3413 deviate from the axis of the first gear disk 3412 and be parallel to the axis of the first gear disk 3412, when the first gear disk 3412 rotates around the axis of the mounting shaft 2, the rotational motion of the first gear disk 3412 around the axis of the mounting shaft 2 can be converted into the eccentric motion of the first eccentric disk 3413. In this way, even if both the first eccentric disk 3413 and the first gear disk 3412 are disc structures, the first eccentric disk 3413 can still complete the eccentric motion.

[0222] It should be noted that the transmission connection between the third massage head 342 and the first eccentric disc 3413 can be a direct transmission connection or an indirect transmission connection through other components. This embodiment does not limit this.

[0223] It is understandable that when both the first eccentric disk 3413 and the first gear disk 3412 are circular structures, compared with elliptical disks or other shapes that can achieve eccentric motion, on the one hand, it facilitates the connection of the first gear disk 3412 with other structures, providing a structural guarantee for the subsequent massage drive 33 to drive the first gear disk 3412 to rotate; on the other hand, it can also simplify the structure of the entire first eccentric component 341 and reduce the cost of the first eccentric component 341.

[0224] Of course, in other embodiments, the first eccentric member 341 can also be an elliptical disk, and the eccentric motion can be achieved through the elliptical disk. This embodiment does not limit this.

[0225] In some embodiments, see Figure 13 , Figure 16 and Figure 17 , Figure 16 yes Figure 10 A schematic diagram of the massage mechanism 100 from another perspective. Figure 17 yes Figure 16 The schematic diagram of the massage mechanism 100 from another perspective shows that the third massage component 34 also includes: a first connecting arm 343 and a first massage arm 344. The first connecting arm 343 is rotatably mounted on the first eccentric disk 3413 about the axis of the first eccentric disk 3413. The first massage arm 344 is hinged to the housing 1 about a first axis O1 parallel to the axis of the mounting shaft 2. The third massage head 342 is connected to the first massage arm 344. The first connecting arm 343 is connected to the first massage arm 344. When the first eccentric disk 3413 moves eccentrically about the axis of the mounting shaft 2, it drives the first massage arm 344 to rotate about the first axis O1 through the first connecting arm 343, so as to drive the third massage head 342 to swing in the swing plane S perpendicular to the axis of the mounting shaft 2.

[0226] In this embodiment, since the first connecting arm 343 is rotatably disposed on the first eccentric disk 3413 about the axis of the first eccentric disk 3413, when the first eccentric disk 3413 makes an eccentric movement, it can drive the first connecting arm 343 to move.

[0227] Next, since the first connecting arm 343 is connected to the first massage arm 344, and since the first massage arm 344 is hinged to the housing 1 around the first axis O1 parallel to the axis of the mounting shaft 2, when the first connecting arm 343 moves, it can drive the first massage arm 344 to swing around the first axis O1.

[0228] When the first massage arm 344 swings around the first axis O1, since the third massage head 342 is connected to the first massage arm 344, it can be driven to swing around the first axis O1 in a synchronous manner.

[0229] Since the first axis O1 is parallel to the mounting axis 2, when the third massage head 342 oscillates around the first axis O1, its oscillation trajectory can lie within an oscillation plane S perpendicular to the axis of the mounting axis 2. In other words, the third massage head 342 can oscillate within this plane. When the third massage head 342 oscillates within the oscillation plane S, a percussive massage effect is achieved.

[0230] Therefore, the first massage head 312 can oscillate in a plane parallel to the axis of the mounting shaft 2, thereby achieving the purpose of kneading massage. The third massage head 342 can oscillate in an oscillation plane S perpendicular to the axis of the mounting shaft 2, thereby achieving the purpose of percussion massage. Throughout the process, the movement trajectory and direction of the first massage head 312 are completely different from those of the third massage head 342. This allows the massage mechanism 100 to massage the area to be massaged from various angles and directions, resulting in a better massage effect.

[0231] To make the third massage head 342 swing more smoothly and stably within the swing plane S, in some embodiments, see... Figure 13 , Figure 16 and Figure 17 The first connecting arm 343 is slidably connected to the first massage arm 344 in a direction parallel to the swing plane S.

[0232] By making the first connecting arm 343 slidably connected to the first massage arm 344 in a direction parallel to the swing plane S, the first connecting arm 343 can more smoothly and stably convert the eccentric motion of the first eccentric disc 3413 into the swing motion of the first massage arm 344 around the first axis O1, thereby making the third massage head 342 swing more smoothly and stably in the swing plane S.

[0233] The first connecting arm 343 can be slidably connected to the first massage arm 344 in a direction parallel to the swing plane S in various ways. In one possible implementation, see [link to relevant documentation]. Figure 13 and Figure 17 The first massage arm 344 may be provided with a guide rod 3441 extending in a direction parallel to the swing plane S, and the first connecting arm 343 may be provided with a guide hole 3431. The guide rod 3441 is slidably inserted into the guide hole 3431. In this way, the first connecting arm 343 can be slidably connected to the first massage arm 344 in a direction parallel to the swing plane S.

[0234] Of course, the purpose of slidably connecting the first connecting arm 343 to the first massage arm 344 in a direction parallel to the swing plane S can also be achieved in other possible ways, and this embodiment does not limit this.

[0235] In some embodiments, see Figure 18 , Figure 18 yes Figure 3The schematic diagram of the massage mechanism 100 from another perspective shows that the fourth massage component 35 includes a second eccentric member 351 and a fourth massage head 352. The second eccentric member 351 is rotatably sleeved on the mounting shaft 2. The second eccentric member 351 is connected to the massage drive member 33 and is configured to perform eccentric motion around the axis of the mounting shaft 2 under the drive of the massage drive member 33. The fourth massage head 352 is disposed on the second eccentric member 351. When the second eccentric member 351 moves eccentrically around the axis of the mounting shaft 2, it drives the fourth massage head 352 to move.

[0236] The structure of the fourth massage component 35 can be the same as or similar to that of the third massage component 34 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the third massage component 34 in the above embodiments. The fourth massage component 35 will not be described again in this embodiment.

[0237] In some embodiments, see Figure 18 The second eccentric component 351 includes a second gear disk 3511 and a second eccentric disk 3512. The second gear disk 3511 is sleeved on the mounting shaft 2 and coaxial with the mounting shaft 2. The massage drive component 33 is also used to drive the second gear disk 3511 to rotate around the mounting shaft 2. The second eccentric disk 3512 is eccentrically disposed on the second gear disk 3511. The axis of the second eccentric disk 3512 is parallel to the axis of the second gear disk 3511. The second eccentric disk 3512 is disposed opposite to the first eccentric disk 3413. The fourth massage head 352 is connected to the second eccentric disk 3512 in a transmission connection. When the second eccentric disk 3512 moves eccentrically around the axis of the mounting shaft 2, it drives the fourth massage head 352 to move.

[0238] The structure of the second eccentric member 351 can be the same as or similar to that of the first eccentric member 341 in the above embodiment, and can bring the same or similar beneficial effects. For details, please refer to the description of the first eccentric member 341 in the above embodiment. The second eccentric member 351 will not be described again in this embodiment.

[0239] In some embodiments, see Figure 4 The spacing adjustment mechanism 4 further includes an adjustment gear 43, which is sleeved on the mounting shaft 2 and located between the first gear disk 3412 and the second gear disk 3511 along the axial direction of the mounting shaft 2. The adjustment drive member 41 is used to drive the adjustment gear 43 to rotate, so as to drive the mounting shaft 2 to rotate.

[0240] Since the adjusting gear 43 is sleeved on the mounting shaft 2, when the adjusting drive component 41 drives the adjusting gear 43 to rotate, it can achieve the purpose of driving the mounting shaft 2 to rotate. Therefore, by sleeved with the adjusting gear 43 on the mounting shaft 2, the adjusting drive component 41 can transmit its own action to the mounting shaft 2 through the adjusting gear 43 via gear transmission, thereby achieving the purpose of driving the mounting shaft 2 to rotate. Because gear transmission has the characteristic of stable transmission, it can be ensured that the adjusting drive component 41 can stably transmit its own action to the mounting shaft 2, thus ensuring the stability of the rotation of the mounting shaft 2.

[0241] In addition, by positioning the adjusting gear 43 between the first gear disk 3412 and the second gear disk 3511, the adjusting gear 43 can make full use of the space between the first gear disk 3412 and the second gear disk 3511, making the structure of the entire massage mechanism 100 more compact and smaller in size.

[0242] In some embodiments, see Figure 18 and Figure 19 , Figure 19 yes Figure 18 The schematic diagram of the transmission component 5 and the massage drive component 33 is shown in the figure. The massage mechanism 100 also includes: transmission component 5, which is connected to the second gear disk 3511 and the first gear disk 3412 respectively. The massage drive component 33 is connected to the transmission component 5 and is used to synchronously drive the first gear disk 3412 and the second gear disk 3511 to rotate around the axis of the mounting shaft 2 through the transmission component 5.

[0243] By setting the transmission component 5, the movement of the massage drive component 33 can be synchronously transmitted to the second gear disk 3511 and the first gear disk 3412 through the transmission component 5, thereby synchronously driving the first massage component 31, the second massage component 32, the third massage component 34 and the fourth massage component 35 to move. There is no need to set separate massage drive components 33 for each of the first massage component 31, the second massage component 32, the third massage component 34 and the fourth massage component 35. Therefore, on the one hand, the number of massage drive components 33 can be reduced, and the cost of the massage mechanism 100 can be reduced. On the other hand, the structure of the massage mechanism 100 can be made more compact and the size smaller.

[0244] There are multiple ways to implement the aforementioned transmission component 5. For one possible implementation, please refer to [link / reference needed]. Figure 19 The transmission assembly 5 includes a transmission shaft 51, a first drive gear 52 and a second drive gear 53. The transmission shaft 51 is rotatably mounted on the housing 1. The first drive gear 52 is sleeved on the transmission shaft 51 and meshes with the first gear disk 3412. The second drive gear 53 is sleeved on the transmission shaft 51 and meshes with the second gear disk 3511.

[0245] The massage drive unit 33 is used to drive the transmission shaft 51 to rotate, so as to synchronously drive the first gear disk 3412 and the second gear disk 3511 to rotate around the axis of the mounting shaft 2 via the first drive gear 52 and the second drive gear 53.

[0246] Since the drive shaft 51 is rotatably mounted on the housing 1, and the first drive gear 52 and the second drive gear 53 are both sleeved on the drive shaft 51, when the massage drive 33 drives the drive shaft 51 to rotate, it can synchronously drive the first drive gear 52 and the second drive gear 53 to rotate.

[0247] Since the first driving gear 52 meshes with the first gear disk 3412 and the second driving gear 53 meshes with the second gear disk 3511, when the first driving gear 52 and the second driving gear 53 rotate with the transmission shaft 51, the purpose of synchronously driving the first gear disk 3412 and the second gear disk 3511 to rotate can be achieved.

[0248] As can be seen, when the transmission assembly 5 includes a transmission shaft 51, a first drive gear 52 and a second drive gear 53, the action of the massage drive 33 can be transmitted to the first gear disk 3412 and the second gear disk 3511 through the meshing between the first drive gear 52 and the first gear disk 3412 and the meshing between the second drive gear 53 and the second gear disk 3511. The implementation method is very simple and can reduce the cost of the transmission assembly 5 to a certain extent.

[0249] Of course, the transmission component 5 can also be implemented in other possible ways, and this embodiment does not limit it.

[0250] To conserve the power of the massage drive component 33, a smaller model of massage drive component 33 can be selected to achieve the purpose of synchronously driving the first gear disk 3412 and the second gear disk 3511 to rotate. In some embodiments, see [reference needed]. Figure 18 and Figure 19 The number of teeth of the first driving gear 52 is less than the number of teeth of the first gear disk 3412.

[0251] By making the number of teeth of the first driving gear 52 less than the number of teeth of the first gear disk 3412, a smaller model of massage drive component 33 can be selected to achieve the purpose of synchronously driving the first gear disk 3412 and the second gear disk 3511 to rotate. In this way, on the one hand, the cost of massage drive component 33 can be reduced, and on the other hand, the volume occupied by massage drive component 33 can be reduced, thereby reducing the overall size of the massage mechanism 100.

[0252] It should be noted that, see Figure 19The number of teeth on the second drive gear 53 can be the same as the number of teeth on the first drive gear 52. This arrangement makes the structure of the entire transmission assembly 5 more regular and facilitates the interchangeability of the second drive gear 53 and the first drive gear 52.

[0253] Of course, the number of teeth of the second driving gear 53 may be different from the number of teeth of the first driving gear 52, and this embodiment does not limit this.

[0254] In some embodiments, see Figure 18 and Figure 19 The transmission assembly 5 also includes a third drive gear 54, which is sleeved on the transmission shaft 51 and located between the first drive gear 52 and the second drive gear 53 along the axial direction of the mounting shaft 2. The third drive gear 54 is connected to the massage drive 33 and the transmission shaft 51 respectively.

[0255] By mounting the third drive gear 54 on the transmission shaft 51 and positioning it between the first drive gear 52 and the second drive gear 53 along the axial direction of the mounting shaft 2, on the one hand, the third drive gear 54 can make full use of the space between the first drive gear 52 and the second drive gear 53, making the structure of the entire massage mechanism 100 more compact. On the other hand, the layout of the first drive gear 52, the third drive gear 54 and the second drive gear 53 on the mounting shaft 2 can be more balanced, and the force can be more balanced.

[0256] Of course, in other embodiments, the first driving gear 52 may be located between the third driving gear 54 and the second driving gear 53, and this embodiment does not limit this.

[0257] In some embodiments, see Figure 3 The spacing adjustment mechanism 4 further includes: a second adjusting member 44, which is sleeved on the mounting shaft 2 and movably disposed on the housing 1 along the axial direction of the mounting shaft 2; a second massage component 32 is at least partially sleeved on the second adjusting member 44, and the second massage component 32 is rotatably connected to the second adjusting member 44. The mounting shaft 2 is configured to drive the second adjusting member 44 to move along the axial direction of the mounting shaft 2 when rotated, thereby causing the second massage component 32 to move relative to the first massage component 31 along the axial direction of the mounting shaft 2.

[0258] The structure of the second adjusting member 44 may be the same as or similar to the structure, operation process and principle of the first adjusting member 42. For details, please refer to the description of the first adjusting member 42 in the above embodiments. This embodiment will not repeat the description here.

[0259] In some embodiments, see Figure 3The mounting shaft 2 is provided with a second external thread 2b, and the second adjusting member 44 is provided with a second internal thread that matches the second external thread 2b. The second internal thread is threadedly connected to the second external thread 2b.

[0260] When the mounting shaft 2 is provided with a second external thread 2b and the second adjusting member 44 is provided with a second internal thread that matches the second external thread 2b, its specific working principle can be the same as or similar to the working principle when the mounting shaft 2 is provided with a first external thread 2a on its peripheral wall and the first adjusting member 42 is provided with a first internal thread 42a that matches the first external thread 2a. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0261] In some embodiments, please continue to see Figure 3 The second external thread 2b and the first external thread 2a are located at the two ends of the mounting shaft 2, respectively.

[0262] By positioning the second external thread 2b and the first external thread 2a at opposite ends of the mounting shaft 2, space can be left in the middle of the mounting shaft 2 to accommodate other components, thereby making the structural layout of the massage mechanism 100 more reasonable and the structure more compact to a certain extent.

[0263] On the other hand, when adjusting the distance between the first massage component 31 and the second massage component 32, the force that causes the first massage component 31 and the second massage component 32 to move along the axial direction of the mounting shaft 2 can be mainly derived from both ends of the mounting shaft 2. In this way, the force on the mounting shaft 2 can be more dispersed, thereby avoiding the situation where the mounting shaft 2 bends and deforms due to excessive force concentration.

[0264] In some embodiments, see Figure 3 The thread direction of the second external thread 2b is opposite to that of the first external thread 2a.

[0265] By making the thread direction of the second external thread 2b opposite to that of the first external thread 2a, the first massage component 31 and the second massage component 32 can move closer to or further away from each other synchronously when the mounting shaft 2 rotates around its own axis. This greatly improves the adjustment efficiency when adjusting the distance between the first massage component 31 and the second massage component 32.

[0266] Of course, in other embodiments, the thread direction of the second external thread 2b may be the same as that of the first external thread 2a, and this embodiment does not limit this.

[0267] Regarding the structure of the second massage component 32, see [link / reference]. Figure 3The second massage component 32 includes a second movable member, a second massage head, and a second swing arm. The second movable member is slidably sleeved on the mounting shaft 2 and rotatably connected to the second adjusting member 44. The second swing arm is disposed on the second movable member, and the second massage head is connected to the second swing arm.

[0268] Specifically, the structure of the second massage component 32 can be the same as or similar to the structure of the first massage component 31 described above. For details, please refer to the description of the first massage component 31 in the above embodiments. This embodiment will not repeat the description here.

[0269] In some embodiments, see Figure 7 The massage mechanism 3 also includes a third massage component 34 and a fourth massage component 35, wherein the third massage component 34 is sleeved on the mounting shaft 2, the fourth massage component 35 is sleeved on the mounting shaft 2, and the massage drive 33 is also used to drive the third massage component 34 and / or the fourth massage component 35 to move.

[0270] The third massage component 34 is fitted onto the first movable member 310, and / or the fourth massage component 35 is fitted onto the second movable member (similar to the way the third massage component 34 is fitted onto the first movable member 310).
