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 actuator. The massage drive drives the first massage component to move, thereby massaging body parts. However, the massage comfort level is often not ideal when using massage devices in these technologies. Summary of the Invention

[0004] This application discloses a massage mechanism and massage device that can improve massage comfort while also being relatively small in size.

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

[0006] chassis;

[0007] Mounting shaft, which is movably disposed 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 both sleeved on the mounting shaft and spaced apart along the axial direction of the mounting shaft, and the first massage component and / or the second massage component moves under the drive of the massage drive component; and,

[0009] A spacing adjustment mechanism, comprising an adjustment drive component disposed on the housing and configured to adjust the length of the mounting shaft to adjust the spacing between the first massage component and the second massage component.

[0010] This massage mechanism incorporates a spacing adjustment mechanism. The adjustment drive of this mechanism can adjust the length of the mounting shaft to regulate the spacing between the first and second massage components. This allows the adjustment drive to move the first and second massage components axially along the mounting shaft when the spacing is inappropriate, preventing them from properly fitting the area to be massaged. This adjustment adjusts the spacing until the components are properly aligned with the area, significantly improving massage comfort and achieving an ideal massage experience.

[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 distance between the first and second massage components can be adjusted by adjusting the length of the mounting shaft. 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 adjusting the length of the mounting shaft, 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] Optionally, the mounting shaft includes:

[0014] A first shaft segment, slidably disposed on the housing along its own axial direction, and a first massage component sleeved on the first shaft segment; and...

[0015] The second shaft segment is slidably disposed on the housing along the axial direction of the first shaft segment, and the second massage component is sleeved on the second shaft segment;

[0016] The adjustment drive is configured to drive at least one of the first shaft segment and the second shaft segment to move along the axial direction of the first shaft segment toward or away from the other, so as to adjust the length of the mounting shaft.

[0017] When the mounting shaft includes a first shaft segment and a second shaft segment, and the adjusting drive member adjusts the length of the mounting shaft by driving at least one of the first shaft segment and the second shaft segment to move along the axial direction of the first shaft segment toward or away from the other, since the first shaft segment and the second shaft segment are relatively independent shaft segments, the first shaft segment and the second shaft segment will not affect each other regardless of whether the adjusting drive member drives the first shaft segment to slide or drives the second shaft segment to slide. This makes the adjustment of the length of the mounting shaft more reliable and avoids the occurrence of adjustment failure.

[0018] Optionally, the spacing adjustment mechanism further includes:

[0019] A threaded adjustment assembly is provided, wherein the adjustment drive is connected to the threaded adjustment assembly, the threaded adjustment assembly is connected to the first shaft segment and the second shaft segment respectively, and the adjustment drive drives at least one of the first shaft segment and the second shaft segment to move along the axial direction of the first shaft segment toward or away from the other through the threaded adjustment assembly.

[0020] Since the threaded adjustment assembly can convert its rotational motion into linear motion by means of threaded transmission, at least one of the first shaft segment and the second shaft segment moves along the axial direction of the first shaft segment toward or away from the other, when selecting the adjustment drive, a common adjustment drive that can output rotational motion can be selected instead of an adjustment drive that needs to directly output linear motion. Therefore, the cost of the adjustment drive can be reduced to a certain extent.

[0021] Optionally, the thread adjustment assembly includes:

[0022] A threaded sleeve, the threaded sleeve extending axially along the first shaft segment; and,

[0023] A threaded component, which extends axially along the first shaft segment, and a threaded sleeve is fitted onto the threaded component and threadedly connected to it.

[0024] The threaded component is rotatably connected to the first shaft segment and the second shaft segment respectively. The threaded sleeve is rotatably disposed on the housing about the axial direction of the first shaft segment. The adjusting drive component is used to drive the threaded sleeve to rotate.

[0025] Since the threaded sleeve is fitted onto the threaded component and connected to it by threads, the threaded sleeve can form a semi-enclosed state around the threaded component. This makes the operating environment of the threaded component safer, thereby ensuring the reliability of the entire pitch adjustment mechanism.

[0026] Optionally, the threaded element includes:

[0027] A first threaded component, rotatably connected to a first shaft segment, and threadedly connected to a threaded sleeve, wherein rotation of the threaded sleeve about the axis of the first shaft segment drives the first threaded component to move axially relative to the threaded sleeve along the first shaft segment; and,

[0028] The second threaded component is rotatably connected to the second shaft segment and threadedly connected to the threaded sleeve. When the threaded sleeve rotates about the axis of the first shaft segment, it drives the second threaded component to move axially relative to the threaded sleeve along the first shaft segment.

[0029] When the threaded component includes a first threaded component and a second threaded component, and the first threaded component is rotatably connected to the first shaft segment and the second threaded component is rotatably connected to the second shaft segment, during the rotation of the threaded sleeve, the first shaft segment and the second shaft segment can be driven to move axially along the first shaft segment at the same time. In this way, the adjustment efficiency when adjusting the length of the mounting shaft can be improved to a certain extent.

[0030] Optionally, the end of the first shaft segment connected to the first threaded component is a connecting end face, and a connecting shaft is provided on the connecting end face. The first threaded component is provided with an insertion hole extending axially along the first shaft segment, and the connecting shaft is inserted into the insertion hole. A rotating component is provided on the end of the connecting shaft opposite to the connecting end face. A portion of the structure of the first threaded component is confined between the rotating component and the connecting end face, so that the first threaded component is rotatably connected to the first shaft segment.

[0031] Since the connecting shaft and rotating parts are both located in the insertion hole of the first threaded part, the first threaded part provides protection for the connecting shaft and rotating parts, making the environment of the connecting shaft and rotating parts more stable, and thus making the connection between the first threaded part and the first shaft segment more stable and reliable.

[0032] Optionally, the rotating component is a bearing.

[0033] When the rotating component is a bearing, the cost of the rotating component can be reduced to some extent because bearing technology is reliable and inexpensive.

[0034] Optionally, the thread direction of the first threaded component is opposite to that of the thread direction of the second threaded component.

[0035] By making the thread direction of the first threaded component opposite to that of the second threaded component, the first massage component and the second massage component can move closer to each other or further away from each other synchronously when the threaded sleeve rotates around the axis of the first shaft segment. This greatly improves the adjustment efficiency when adjusting the distance between the first massage component and the second massage component.

[0036] Optionally, the first threaded component is provided with a guide portion, and the housing is provided with a guide groove. The guide portion is located in the guide groove, and the guide groove is used to guide the guide portion to slide relative to the guide groove along the axial direction of the first shaft segment.

[0037] By setting a guide groove and placing the guide part in the guide groove, the guide groove can guide the guide part, thereby preventing the guide part from rotating around the axis of the first shaft segment. This also prevents the first threaded part from rotating around the axis of the first shaft segment, thus better driving the first threaded part to move axially along the first shaft segment.

[0038] Optionally, the guide portion includes:

[0039] A connecting portion, the connecting portion being connected to the first threaded member; and,

[0040] An extension portion is connected to the connecting portion and extends axially along the first shaft segment. The extension portion is located in the guide groove, which guides the extension portion to slide relative to the guide groove along the axial direction of the first shaft segment.

[0041] Since the extension extends axially along the first shaft segment, the guiding effect of the extension along the first shaft segment is stronger. As a result, when the extension is located in the guide groove, the guide groove guides the extension along the first shaft segment better, thereby making the first threaded part more stable when it moves along the first shaft segment.

[0042] Optionally, the connecting portion is connected to the end of the first threaded member opposite to the threaded sleeve, and the extension portion extends in a direction close to the threaded sleeve.

[0043] When the connecting part is connected to the end of the first threaded component away from the threaded sleeve and the extension part extends in the direction close to the threaded sleeve, the total length of the whole formed by the guide part and the first threaded component along the axial direction of the first shaft segment can be reduced as much as possible, thereby making the structure of the whole formed by the guide part and the first threaded component more compact.

[0044] Optionally, the extension is provided with a mounting hole, a follower is provided in the mounting hole, and a position detection element is provided on the housing, the position detection element being used to detect the position of the follower.

[0045] The change in the distance between the first massage component and the second massage component can be obtained by detecting the change in the position of the follower, thereby providing data support for adjusting the distance between the first massage component and the second massage component to a suitable distance, making the massage mechanism more intelligent.

[0046] Optionally, the threaded sleeve is provided with a first adjusting gear, and the drive shaft of the adjusting drive is provided with a second adjusting gear that meshes with the first adjusting gear.

[0047] When the adjusting drive component drives the threaded sleeve to rotate, it mainly drives the threaded sleeve to rotate through gear transmission. Gear transmission has the characteristics of stable transmission and mature technology. Therefore, it can reduce the cost of the massage mechanism while ensuring the reliable operation of the massage mechanism.

[0048] Optionally, the number of teeth of the first adjusting gear is greater than the number of teeth of the second adjusting gear.

[0049] By making the number of teeth on the first adjusting gear greater than the number of teeth on the second adjusting gear, the adjusting drive component can be made less labor-intensive. This allows a smaller size adjusting drive component to be used to drive the threaded sleeve to rotate. In this way, on the one hand, the cost of the adjusting drive component can be reduced, and on the other hand, the size of the adjusting drive component can be reduced, which in turn reduces the size of the entire massage mechanism.

[0050] Optionally, the thread adjustment assembly further includes:

[0051] A limiting component is connected to the housing and covers the threaded sleeve, the threaded sleeve being rotatably connected to the limiting component about the axis of the first shaft segment.

[0052] By setting a limiting component and making the limiting component cover the threaded sleeve and rotatably connected to the threaded sleeve around the axis of the first shaft segment, the limiting component can further limit the position of the threaded sleeve, making the threaded sleeve more stable when rotating around the axis of the first shaft segment.

[0053] Optionally, the limiting component includes:

[0054] A first limiting member, connected to the housing and covering the threaded sleeve; and

[0055] The second limiting member is connected to the housing and covers the threaded sleeve;

[0056] The threaded sleeve is rotatably connected to the first limiting member and the second limiting member respectively around the axial direction of the first shaft segment.

[0057] By connecting both the first and second limiting members to the housing and covering the threaded sleeve, the threaded sleeve can be limited from various positions as much as possible, thereby making the threaded sleeve more stable when it is rotatably mounted on the housing around the axis of the first shaft segment.

[0058] Optionally, the first limiting member and the second limiting member are located on both sides of the first adjusting gear along the axial direction of the first shaft segment.

[0059] By positioning the first and second limiting members on both sides of the first adjusting gear along the axial direction of the first shaft segment, the first and second limiting members can limit the threaded sleeve from both sides of the first adjusting gear, thereby making the threaded sleeve more stable when rotating around the axis of the first shaft segment.

[0060] Optionally, the first limiting member is a retaining ring structure, which covers the threaded sleeve and has one end connected to the housing and the other end being a free end along the circumferential direction of the threaded sleeve; or, both ends of the retaining ring structure along the circumferential direction of the threaded sleeve are connected to the housing.

[0061] And / or,

[0062] The second limiting member is a retaining ring structure. The retaining ring structure covers the threaded sleeve, and one end of the retaining ring structure along the circumference of the threaded sleeve is connected to the housing, while the other end is a free end. Alternatively, both ends of the retaining ring structure along the circumference of the threaded sleeve are connected to the housing.

[0063] When one end of the first limiting member is connected to the housing along the circumferential direction of the threaded sleeve, and the other end is a free end, it makes it easier to assemble the first limiting member into the housing.

[0064] When both ends of the first limiting member along the circumference of the threaded sleeve are connected to the housing, the first limiting member can better limit the threaded sleeve, thereby making the threaded sleeve more stable when rotating around the axis of the first shaft segment.

[0065] Optionally, the first shaft segment and the second shaft segment are rotatably disposed on the housing about the axis of the first shaft segment, and the massage drive is used to drive the first shaft segment and / or the second shaft segment to rotate about the axis of the first shaft segment, so as to drive the first massage assembly and / or the second massage assembly to move.

[0066] When the massage drive unit moves the first massage component and / or the second massage component, it indirectly drives the first shaft segment and / or the second shaft segment to rotate around the axis of the first shaft segment, resulting in a simple structure. In this way, the massage drive unit does not need to directly drive the first massage component and / or the second massage component, which simplifies the structure of the first and second massage components to a certain extent and reduces their cost.

[0067] Optionally, the massage facility may also include:

[0068] A transmission assembly is provided, wherein the massage drive is connected to the transmission assembly, and the transmission assembly is respectively connected to the first shaft segment and the second shaft segment. The transmission assembly is configured to remain connected to the first shaft segment when the first shaft segment moves along its own axial direction, and to remain connected to the second shaft segment when the second shaft segment moves along the axial direction of the first shaft segment.

[0069] By setting up a transmission component, the movement of the massage drive can be synchronously transmitted to the first and second shaft segments, thereby synchronously driving the first and second massage components to move. There is no need to set up separate massage drive components for the first and second massage components. Therefore, on the one hand, the number of massage drive components can be reduced, and the cost of the massage mechanism can be reduced. On the other hand, the structure of the massage mechanism can be made more compact and the size smaller.

[0070] Optionally, the transmission assembly includes:

[0071] The first driven gear is slidable along the axial direction of the first shaft segment and is anti-rotatingly sleeved on the first shaft segment. The massage drive is used to drive the first driven gear to rotate.

[0072] When the transmission component includes a first driven gear, and the first driven gear is slidable along the axial direction of the first shaft segment and anti-rotation sleeved on the first shaft segment, it is possible to achieve the purpose of massaging through the first massage component while adjusting the distance between the first massage component and the second massage component. 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.

[0073] Optionally, a first anti-rotation part is provided on the first shaft segment, and a second anti-rotation part matching the first anti-rotation part is provided in the mounting hole of the first driven gear.

[0074] By cooperating between the first anti-rotation part and the second anti-rotation part, the purpose of preventing the first driven gear and the first shaft segment from rotating axially around the first shaft segment can be achieved. The structure is simple, and therefore, the cost of the massage mechanism can be reduced to a certain extent.

[0075] Optionally, the first shaft segment has a cutting section, which constitutes the first anti-rotation section.

[0076] By making the cutting part on the first shaft section constitute the first anti-rotation part, the formation of the first anti-rotation part can be made very simple, without increasing the cost of making the first anti-rotation part, thereby achieving the goal of reducing the cost of the massage mechanism.

[0077] Optionally, the transmission assembly further includes:

[0078] A second driven gear, which is slidable along the axial direction of the second shaft segment and is anti-rotatingly sleeved on the second shaft segment; and,

[0079] A drive shaft is rotatably mounted on the housing about the first shaft segment. A first drive gear meshes with the first driven gear and a second drive gear meshes with the second driven gear. The massage drive is used to drive the drive shaft to rotate.

[0080] When the transmission assembly also includes a second driven gear and a transmission shaft, the action of the massage drive component can be transmitted to the first shaft segment and the second shaft segment through the meshing of the first driven gear and the first driving gear, and the meshing of the second driven gear and the second driving gear. That is, the action of the massage drive component is transmitted to the first shaft segment and the second shaft segment through gear transmission. The implementation method is simple and reliable. Therefore, the cost of the transmission assembly can be reduced to a certain extent.

[0081] Optionally, the transmission assembly further includes:

[0082] A first bevel gear, which is sleeved on the drive shaft; and...

[0083] The second bevel gear meshes with the first bevel gear, and the massage drive is used to drive the second bevel gear to rotate.

[0084] When the transmission assembly also includes a first bevel gear and a second bevel gear, the arrangement of the massage drive component in the massage mechanism can be changed through the cooperation of the first bevel gear and the second bevel gear. In this way, when arranging the massage drive component, the position of the massage drive component can be reasonably arranged according to the space of the massage mechanism, so as to make full use of the space of the massage mechanism and thus achieve the effect of making the structure of the massage mechanism more compact.

[0085] Optionally, the axial direction of the first bevel gear is perpendicular to the axial direction of the second bevel gear.

[0086] By making the axis of the first bevel gear perpendicular to the axis of the second bevel gear, the layout of the first and second bevel gears can be made more regular. On the one hand, this facilitates the assembly of the first and second bevel gears, and on the other hand, it also makes the overall structure of the massage mechanism more regular, which is convenient for subsequent maintenance.

[0087] Optionally, a turbine coaxial with the second bevel gear is provided on the second bevel gear, and a worm gear is provided on the drive shaft of the massage drive component, the worm gear meshing with the turbine gear.

[0088] The massage drive unit can transmit its motion to the second bevel gear through a worm gear. Since the worm gear can change the transmission direction, it can make more efficient use of the space in the massage mechanism, thus making the structure of the massage mechanism more compact.

[0089] Optionally, the first massage component includes:

[0090] A motion conversion assembly, the motion conversion assembly being sleeved on the first shaft segment; and,

[0091] A first massage head is connected to the motion conversion assembly, which converts the rotational motion of the first shaft segment into the oscillating motion of the first massage head.

[0092] Since the motion conversion component is sleeved on the first shaft segment and the first massage head is connected to the motion conversion component, when the first shaft segment starts to rotate, the rotational motion of the first shaft segment can be converted into the oscillating motion of the first massage head under the action of the motion conversion component. When the first massage head starts to oscillate, it can create a kneading or pounding massage effect on the area to be massaged, thus improving the massage effect.

[0093] Optionally, the motion conversion component includes a slanted wheel, which is sleeved on the first shaft segment. The first massage head is rotatably sleeved on the peripheral wall of the slanted wheel via a swing arm around the axis of the slanted wheel. The housing is provided with a clearance hole, the shape and size of which match the motion trajectory of the swing arm.

[0094] When the motion conversion component includes a slanted wheel, the rotational motion of the slanted wheel can be cleverly converted into the oscillating motion of the first massage head. Complex functions can be accomplished with a simple structure. The structural design is very ingenious and can reduce the cost of the motion conversion component to a certain extent.

[0095] Optionally, the slanted wheel has a plurality of grooves on its peripheral wall, the plurality of grooves being spaced apart circumferentially along the slanted wheel, and each groove extending axially along the slanted wheel.

[0096] By setting multiple grooves on the peripheral wall of the inclined shaft wheel, the contact area between the swing arm and the peripheral wall of the inclined shaft wheel can be reduced when the swing arm is fitted onto the peripheral wall of the inclined shaft wheel, thereby making the swing arm rotate more smoothly around the axis of the inclined shaft wheel.

[0097] Optionally, the slant wheel has a blocking element;

[0098] The motion conversion assembly further includes a pressure cap disposed on the inclined shaft wheel, and the swing arm is limited between the pressure cap and the blocking member.

[0099] By positioning the swing arm between the pressure cap and the blocking member, the swing arm can be stably fitted onto the peripheral wall of the inclined shaft wheel, thereby preventing the swing arm from slipping off the peripheral wall of the inclined shaft wheel.

[0100] Optionally, the pressure cap is detachably disposed on the inclined shaft wheel.

[0101] By making the pressure cap detachably connected to the slant wheel, it becomes easier and faster to rotatably mount the swing arm around the axis of the slant wheel onto the circumferential wall of the slant wheel.

[0102] Optionally, the housing includes:

[0103] First shell; and,

[0104] The second housing is detachably fastened to the first housing, and together they form a mounting cavity. At least a portion of the structure of the spacing adjustment mechanism, the massage mechanism, and the mounting shaft are located within the mounting cavity.

[0105] By locating at least a portion of the spacing adjustment mechanism, massage mechanism, and mounting shaft within the mounting cavity, the entire massage mechanism achieves a cleaner appearance and enhances its aesthetic appeal. Furthermore, the housing provides protection for these structures, resulting in more stable operation of the massage mechanism.

[0106] Secondly, this application discloses a massage device, including the massage mechanism described in any of the first aspects above.

[0107] 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.

[0108] Compared with the prior art, the beneficial effects of this application are as follows:

[0109] In this application, by setting a spacing adjustment mechanism and enabling the adjustment drive of the spacing adjustment mechanism to adjust the length of the mounting shaft 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 adjust the length of the mounting shaft to drive the first massage component and the second massage component to move along the axial direction of the mounting shaft 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.

[0110] 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 distance between the first and second massage components can be adjusted by adjusting the length of the mounting shaft. 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 adjusting the length of the mounting shaft, providing a structural guarantee for adjusting the distance between the first and second massage components.

[0111] 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.

[0112] Furthermore, since adjusting the distance between the first massage component and the second massage component can be achieved by adjusting the length of the mounting shaft to drive the first massage component and the second massage component to move, specifically, by extending the length of the mounting shaft, the distance between the first massage component and the second massage component can be increased, and by shortening the length of the mounting shaft, the distance between the first massage component and the second massage component can be decreased. The principle is very simple, which can simplify the structure of the massage mechanism to a certain extent and reduce the cost of the massage mechanism. Attached Figure Description

[0133] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0134] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0135] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0136] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0137] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0138] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0139] Figure 1 This is a schematic diagram of the structure of a massage mechanism 100 provided in one embodiment of this application. Figure 2 yes Figure 1 Exploded view of the massage mechanism 100 in the middle. Figure 3 yes Figure 2 A schematic diagram of the further disassembled structure of the massage mechanism 100.

[0140] See Figure 1 , Figure 2 and Figure 3The massage mechanism 100 includes: a housing 1, a mounting shaft 2, a massage mechanism 3, and a spacing adjustment mechanism 4. The mounting shaft 2 is movably mounted on the housing 1. 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 both sleeved on the mounting shaft 2 and are spaced apart along the axial direction of the mounting shaft 2. The first massage component 31 and / or the second massage component 32 move under the drive of the massage drive component 33.

[0141] The spacing adjustment mechanism 4 includes an adjustment drive 41, which is disposed in the housing 1 and configured to adjust the length of the mounting shaft 2 to adjust the spacing between the first massage component 31 and the second massage component 32.

[0142] 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.

[0143] 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.

[0144] 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 can adjust the length of the mounting shaft 2 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 length of the mounting shaft 2 to move the first massage component 31 and the second massage component 32 along the axial direction of the mounting shaft 2, thereby adjusting the spacing between the first massage component 31 and the second massage component 32 until the spacing between the first massage component 31 and the second massage component 32 can be well adapted to the massaged area, thus greatly improving the massage comfort and making the massage comfort ideal.

[0145] 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 adjusting the length of the mounting shaft 2. Therefore, the same mounting shaft 2 can be used to fit both the first massage component 31 and the second massage component 32, providing a structural guarantee for subsequent massage by adjusting the drive 41 to drive the first massage component 31 and / or the second massage component 32 to move. At the same time, the distance between the first massage component 31 and the second massage component 32 can also be adjusted by adjusting the length of the mounting shaft 2, providing a structural guarantee for adjusting the distance between the first massage component 31 and the second massage component 32.

[0146] 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.

[0147] Furthermore, since adjusting the distance between the first massage component 31 and the second massage component 32 can be achieved by adjusting the length of the mounting shaft 2 to drive the first massage component 31 and the second massage component 32 to move, specifically, by extending the length of the mounting shaft 2, the distance between the first massage component 31 and the second massage component 32 can be increased, and by shortening the length of the mounting shaft 2, the distance between the first massage component 31 and the second massage component 32 can be decreased. The principle is very simple, which can simplify the structure of the massage mechanism 100 to a certain extent and reduce the cost of the massage mechanism 100.

[0148] It should be noted that the aforementioned adjustment drive component 41 and massage drive component 33 can both be motors or other possible drive elements, and this embodiment does not limit them.

[0149] 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.

[0150] 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 adjusting the length of the mounting shaft 2. 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 achieving a more ideal massage experience.

[0151] There are multiple ways to adjust the length of the mounting shaft 2 using the aforementioned adjustment drive 41. In one possible implementation, when the mounting shaft 2 is a telescopic antenna structure, in order to adjust the length of the mounting shaft 2, one end of the mounting shaft 2 can be fixedly set, and the other positions of the mounting shaft 2 can be movably set in the housing 1. The adjustment drive 41 can pull or push the mounting shaft 2 at the other end of the mounting shaft 2, thereby achieving the purpose of adjusting the length of the mounting shaft 2.

[0152] In another possible implementation, see Figure 2 and Figure 4 , Figure 4 yes Figure 2 The disassembled structural diagram of the massage mechanism 100 (excluding the housing 1) shows that the mounting shaft 2 includes a first shaft segment 21 and a second shaft segment 22, wherein the first shaft segment 21 is along its own axial direction ( Figure 2 The first massage component 31 is sleeved on the first shaft segment 21, and the second shaft segment 22 is slidably disposed on the housing 1 along the axial direction of the first shaft segment 21. The second massage component 32 is sleeved on the second shaft segment 22. The adjustment drive 41 is configured to drive at least one of the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21 toward or away from the other, so as to adjust the length of the mounting shaft 2.

[0153] Since the mounting shaft 2 includes a first shaft segment 21 and a second shaft segment 22, and both the first shaft segment 21 and the second shaft segment 22 are slidably disposed on the housing 1 along the axial direction of the first shaft segment 21, when the adjusting drive 41 drives at least one of the first shaft segment 21 and the second shaft segment 22 to move closer to or further away from the other along the axial direction of the first shaft segment 21, the total length of the first shaft segment 21 and the second shaft segment 22 can be lengthened or shortened, thereby achieving the purpose of adjusting the length of the mounting shaft 2.

[0154] Based on this, since the first massage component 31 is sleeved on the first shaft segment 21 and the second massage component 32 is sleeved on the second shaft segment 22, when the adjusting drive 41 drives at least one of the first shaft segment 21 and the second shaft segment 22 to move closer to or further away from the other along the axial direction of the first shaft segment 21, the distance between the first massage component 31 and the second massage component 32 can be made smaller or larger, thereby achieving the purpose of adjusting the distance between the first massage component 31 and the second massage component 32.

[0155] When the mounting shaft 2 includes a first shaft segment 21 and a second shaft segment 22, and the adjusting drive 41 adjusts the length of the mounting shaft 2 by driving at least one of the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21 toward or away from the other, since the first shaft segment 21 and the second shaft segment 22 are relatively independent shaft segments, the first shaft segment 21 and the second shaft segment 22 will not affect each other regardless of whether the adjusting drive 41 drives the first shaft segment 21 to slide or drives the second shaft segment 22 to slide. This makes the adjustment of the length of the mounting shaft 2 more reliable and avoids the occurrence of adjustment failure.

[0156] The aforementioned adjusting drive 41 can drive at least one of the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21 toward or away from the other in various ways. In one possible implementation, see [link to relevant documentation]. Figure 4 and Figure 5 , Figure 5 yes Figure 4 The schematic diagram of the spacing adjustment mechanism 4 is shown. The spacing adjustment mechanism 4 also includes: a threaded adjustment component 42, an adjustment drive component 41 is connected to the threaded adjustment component 42, the threaded adjustment component 42 is connected to the first shaft segment 21 and the second shaft segment 22 respectively, and the adjustment drive component 41 drives at least one of the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21 toward or away from the other through the threaded adjustment component 42.

[0157] Since the adjusting drive 41 is connected to the first shaft segment 21 and the second shaft segment 22 respectively through the threaded adjusting assembly 42, when it is necessary to drive at least one of the first shaft segment 21 and the second shaft segment 22 to move closer to or further away from the other along the axial direction of the first shaft segment 21, firstly, the adjusting drive 41 can drive the threaded adjusting assembly 42 to move. When the threaded adjusting assembly 42 starts to move, it can achieve the purpose of driving the first shaft segment 21 and the second shaft segment 22 connected to the threaded adjusting assembly 42 to move closer to or further away from the other along the axial direction of the first shaft segment 21.

[0158] Since the threaded adjustment assembly 42 can convert its rotational motion into linear motion by means of threaded transmission, at least one of the first shaft segment 21 and the second shaft segment 22 moves along the axial direction of the first shaft segment 21 toward or away from the other, when selecting the adjustment drive 41, a common adjustment drive 41 that can output rotational motion can be selected instead of an adjustment drive 41 that needs to directly output linear motion. Therefore, the cost of the adjustment drive 41 can be reduced to a certain extent.

[0159] In some embodiments, see Figure 3 , Figure 5 and Figure 6 , Figure 6 yes Figure 5 The spacing adjustment mechanism 4 is shown in a structural schematic diagram from another perspective. The threaded adjustment assembly 42 includes a threaded sleeve 421 and a threaded component 422. The threaded sleeve 421 extends axially along the first shaft segment 21, and the threaded component 422 extends axially along the first shaft segment 21. The threaded sleeve 421 is sleeved on the threaded component 422 and is threadedly connected to the threaded component 422.

[0160] The threaded component 422 is rotatably connected to the first shaft segment 21 and the second shaft segment 22 respectively. The threaded sleeve 421 is rotatably mounted on the housing 1 around the axis of the first shaft segment 21. The adjusting drive component 41 is used to drive the threaded sleeve 421 to rotate, so as to drive the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21 towards or away from the other.

[0161] In this embodiment, since the threaded sleeve 421 extends axially along the first shaft segment 21 and is rotatably disposed on the housing 1 about the axis of the first shaft segment 21, the adjusting drive member 41 can drive the threaded sleeve 421 to rotate about the axis of the first shaft segment 21.

[0162] Next, since the threaded sleeve 421 is fitted onto and threadedly connected to the threaded component 422, when the threaded sleeve 421 rotates about the axis of the first shaft segment 21, it can drive the threaded component 422 to move axially along the first shaft segment 21. That is, the threaded sleeve 421 can convert its own rotational motion about the axis of the first shaft segment 21 into linear motion of the threaded component 422 along the axis of the first shaft segment 21.

[0163] When the threaded part 422 moves along the axial direction of the first shaft segment 21, since the threaded part 422 is rotatably connected to the first shaft segment 21 and the second shaft segment 22 respectively, the threaded part 422 can drive the first shaft segment 21 and the second shaft segment 22 to move along the axial direction of the first shaft segment 21, thereby achieving the purpose of adjusting the length of the mounting shaft 2.

[0164] Since the threaded sleeve 421 is fitted onto the threaded part 422 and is threadedly connected to the threaded part 422, the threaded sleeve 421 can form a semi-enclosed state on the threaded part 422. This makes the operating environment of the threaded part 422 safer, thereby ensuring the reliability of the entire spacing adjustment mechanism 4.

[0165] In some embodiments, see Figure 3 , Figure 5 and Figure 6 The threaded component 422 includes a first threaded component 4221 and a second threaded component 4222. The first threaded component 4221 is rotatably connected to the first shaft segment 21 and is threadedly connected to the threaded sleeve 421. When the threaded sleeve 421 rotates around the axis of the first shaft segment 21, it drives the first threaded component 4221 to move relative to the threaded sleeve 421 along the axial direction of the first shaft segment 21, thereby driving the first shaft segment 21 to move.

[0166] The second threaded component 4222 is rotatably connected to the second shaft segment 22. The second threaded component 4222 is threadedly connected to the threaded sleeve 421. When the threaded sleeve 421 rotates around the axis of the first shaft segment 21, it drives the second threaded component 4222 to move relative to the threaded sleeve 421 along the axial direction of the first shaft segment 21, thereby driving the second shaft segment 22 to move.

[0167] Since the first threaded component 4221 is rotatably connected to the first shaft segment 21 and the first threaded component 4221 is threadedly connected to the threaded sleeve 421, when the threaded sleeve 421 rotates around the axis of the first shaft segment 21, it can drive the first threaded component 4221 to move relative to the threaded sleeve 421 along the axial direction of the first shaft segment 21, thereby driving the first shaft segment 21 to move along the axial direction of the first shaft segment 21.

[0168] In addition, since the second threaded component 4222 is rotatably connected to the second shaft segment 22 and the second threaded component 4222 is threadedly connected to the threaded sleeve 421, when the threaded sleeve 421 rotates around the axis of the first shaft segment 21, it can also drive the second threaded component 4222 to move relative to the threaded sleeve 421 along the axial direction of the first shaft segment 21, thereby driving the second shaft segment 22 to move along the axial direction of the first shaft segment 21.

[0169] As can be seen, when the threaded component 422 includes a first threaded component 4221 and a second threaded component 4222, and the first threaded component 4221 is rotatably connected to the first shaft segment 21 and the second threaded component 4222 is rotatably connected to the second shaft segment 22, during the rotation of the threaded sleeve 421, the first shaft segment 21 and the second shaft segment 22 can be driven to move axially along the first shaft segment 21 simultaneously. In this way, the adjustment efficiency when adjusting the length of the mounting shaft 2 can be improved to a certain extent.

[0170] It should be noted that there are multiple ways to achieve the rotatable connection between the first shaft segment 21 and the first threaded component 4221. In one possible implementation, see [link to relevant documentation]. Figure 4 , Figure 6 and Figure 7 , Figure 7 yes Figure 4 The diagram shows the structure of the first shaft segment 21 after it has been removed from the first threaded component 4221. The end of the first shaft segment 21 connected to the first threaded component 4221 is a connecting end face 211. A connecting shaft 2111 is provided on the connecting end face 211. An insertion hole 4221a extending axially along the first shaft segment 21 is provided on the first threaded component 42211. The connecting shaft 2111 is inserted into the insertion hole 4221a. A rotating component 2111a is provided on the end of the connecting shaft 2111 that is away from the connecting end face 211. A portion of the structure of the first threaded component 4221 is confined between the rotating component 2111a and the connecting end face 211, so that the first threaded component 4221 is rotatably connected to the first shaft segment 21.

[0171] Since the connecting shaft 2111 is inserted into the insertion hole 4221a, and a rotating member 2111a is provided at the end of the connecting shaft 2111 that is away from the connecting end face 211, and part of the structure of the first threaded member 4221 is limited between the rotating member 2111a and the connecting end face 211, when the connecting shaft 2111 is inserted into the insertion hole 4221a, the connecting shaft 2111 cannot be pulled out from the insertion hole 4221a of the first threaded member 4221, thereby achieving the purpose of rotatably connecting the first threaded member 4221 and the first shaft segment 21.

[0172] Since the connecting shaft 2111 and the rotating component 2111a are both located in the insertion hole 4221a of the first threaded component 4221, the first threaded component 4221 provides protection for the connecting shaft 2111 and the rotating component 2111a, making the environment of the connecting shaft 2111 and the rotating component 2111a more stable, and thus making the connection between the first threaded component 4221 and the first shaft segment 21 more stable and reliable.

[0173] The aforementioned rotating component 2111a can be any possible component, for example, see [reference needed]. Figure 7 The rotating component 2111a is a bearing.

[0174] When the rotating component 2111a is a bearing, the cost of the rotating component 2111a can be reduced to a certain extent because bearing technology is reliable and inexpensive.

[0175] Of course, the rotating part 2111a can also be other possible structures, as long as it can ensure that the first threaded part 4221 and the first shaft segment 21 can be rotatably connected. This embodiment does not limit this.

[0176] It should be noted that the way the second threaded component 4222 is rotatably connected to the second shaft segment 22 can be similar to the way the first threaded component 4221 is rotatably connected to the first shaft segment 21. For details, please refer to the description of the rotatable connection between the first threaded component 4221 and the first shaft segment 21 in the above embodiment. The way the second threaded component 4222 is rotatably connected to the second shaft segment 22 will not be described again in this embodiment.

[0177] In some embodiments, see Figure 6 and Figure 7 The thread direction of the first threaded part 4221 is opposite to that of the thread direction of the second threaded part 4222.

[0178] By making the thread direction of the first threaded component 4221 opposite to that of the second threaded component 4222, the first massage component 31 and the second massage component 32 can move closer to each other or further away from each other synchronously when the threaded sleeve 421 rotates around the axis of the first shaft segment 21. This greatly improves the adjustment efficiency when adjusting the distance between the first massage component 31 and the second massage component 32.

[0179] Of course, in other embodiments, the thread direction of the first threaded component 4221 and the thread direction of the second threaded component 4222 may be the same, and this embodiment does not limit this.

[0180] To better drive the first threaded component 4221 to move axially along the first shaft segment 21 when the threaded sleeve 421 rotates around the axis of the first shaft segment 21, and to avoid the situation where the first threaded component 4221 follows the rotation of the threaded sleeve 421, thus failing to convert the rotational motion of the threaded sleeve 421 into the linear motion of the first threaded component 4221, in some embodiments, see... Figure 7 and Figure 8 , Figure 8 yes Figure 1 Another exploded view of the massage mechanism 100 shows that a guide portion 42211 is provided on the first threaded part 4221, and a guide groove 11 is provided on the housing 1. The guide portion 42211 is located in the guide groove 11, and the guide groove 11 is used to guide the guide portion 42211 to slide relative to the guide groove 11 along the axial direction of the first shaft segment 21.

[0181] By setting the guide groove 11 and placing the guide part 42211 in the guide groove 11, the guide groove 11 can guide the guide part 42211, thereby preventing the guide part 42211 from rotating around the axis of the first shaft segment 21. This also prevents the first threaded part 4221 from rotating around the axis of the first shaft segment 21, thus better driving the first threaded part 4221 to move along the axial direction of the first shaft segment 21.

[0182] In some embodiments, see Figure 8 and Figure 9 , Figure 9 yes Figure 8 A schematic diagram of the structure of the first threaded component 4221 is shown. The guide portion 42211 includes a connecting portion 42211a and an extension portion 42211b. The connecting portion 42211a is connected to the first threaded component 4221, and the extension portion 42211b is connected to the connecting portion 42211a and extends along the axial direction of the first shaft segment 21. The extension portion 42211b is located in the guide groove 11, and the guide groove 11 is used to guide the extension portion 42211b to slide relative to the guide groove 11 along the axial direction of the first shaft segment 21.

[0183] Since the extension 42211b extends along the axial direction of the first shaft segment 21, the guiding effect of the extension 42211b along the axial direction of the first shaft segment 21 can be strengthened. As a result, when the extension 42211b is located in the guide groove 11, the guide groove 11 provides better guidance for the extension 42211b along the axial direction of the first shaft segment 21, thereby making the first threaded part 4221 more stable when moving along the axial direction of the first shaft segment 21.

[0184] In some embodiments, see Figure 8 and Figure 9 The connecting part 42211a is connected to one end of the first threaded member 4221 that is away from the threaded sleeve 421. Figure 8 The left end of the first threaded part 4221), the extension 42211b along the direction close to the threaded sleeve 421 ( Figure 8 (Extends in the direction from the center to the right).

[0185] When the connecting part 42211a is connected to the end of the first threaded member 4221 that is away from the threaded sleeve 421 and the extension part 42211b extends in the direction close to the threaded sleeve 421, the total length of the whole formed by the guide part 42211 and the first threaded member 4221 along the axial direction of the first shaft segment 21 can be reduced as much as possible, thereby making the structure of the whole formed by the guide part 42211 and the first threaded member 4221 more compact.

[0186] Of course, in other embodiments, the extension 42211b may also be in a direction away from the threaded sleeve 421. Figure 8 Extending in the direction from center to left, this embodiment does not limit this.

[0187] 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 8 and Figure 9The extension 42211b is provided with a mounting hole 42211c, and a follower 12 is provided in the mounting hole 42211c. The housing 1 is provided with a position detection element 13, which is used to detect the position of the follower 12.

[0188] In this way, the change in the distance between the first massage component 31 and the second massage component 32 can be obtained by detecting the change in the position of the follower 12, 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.

[0189] The position detection element 13 can be a sliding rheostat or other possible electronic components that can detect the position of the follower 12. This embodiment does not limit the position detection element 13.

[0190] In some embodiments, see Figure 6 The threaded sleeve 421 is provided with a first adjusting gear 4211, and the drive shaft of the adjusting drive member 41 is provided with a second adjusting gear 411 that meshes with the first adjusting gear 4211. The drive shaft of the adjusting drive member 41 is used to drive the second adjusting gear 411 to rotate, so as to drive the threaded sleeve 421 to rotate around the axis of the first shaft segment 21 through the first adjusting gear 4211.

[0191] Since the threaded sleeve 421 is provided with a first adjusting gear 4211 and the drive shaft of the adjusting drive member 41 is provided with a second adjusting gear 411, and since the second adjusting gear 411 meshes with the first adjusting gear 4211, when the drive shaft of the adjusting drive member 41 starts to rotate, it can drive the second adjusting gear 411 to rotate, and then drive the threaded sleeve 421 to rotate through the first adjusting gear 4211, thereby achieving the purpose of driving the threaded sleeve 421 to rotate through the adjusting drive member 41.

[0192] It can be seen that when the adjusting drive component 41 drives the threaded sleeve 421 to rotate, it mainly drives the threaded sleeve 421 to rotate through gear transmission. Gear transmission has the characteristics of stable transmission and mature technology. Therefore, it can reduce the cost of the massage mechanism 100 while ensuring the reliable operation of the massage mechanism 100.

[0193] Of course, in other embodiments, the adjusting drive 41 can also drive the threaded sleeve 421 to rotate in other ways, such as by using a synchronous belt pulley. This embodiment does not limit this.

[0194] To conserve the force required to adjust the drive component 41, allowing for the selection of a smaller massage drive component 33 to achieve the desired rotation of the threaded sleeve 421, in some embodiments, see [reference needed]. Figure 5 and Figure 6 The number of teeth of the first adjusting gear 4211 is greater than the number of teeth of the second adjusting gear 411.

[0195] By making the number of teeth of the first adjusting gear 4211 greater than the number of teeth of the second adjusting gear 411, the adjusting drive component 41 can be made less labor-intensive. This allows a smaller size of the adjusting drive component 41 to be used to drive the threaded sleeve 421 to rotate. In this way, on the one hand, the cost of the adjusting drive component 41 can be reduced, and on the other hand, the volume occupied by the adjusting drive component 41 can be reduced, thereby making the overall massage mechanism 100 smaller.

[0196] To ensure greater stability when the threaded sleeve 421 is rotatably mounted on the housing 1 around the axis of the first shaft segment 21, and to prevent localized warping or misalignment of the threaded sleeve 421 after prolonged rotation, in some embodiments, see... Figure 5 The threaded adjustment assembly 42 also includes a limiting assembly 423, which is connected to the housing 1 and covers the threaded sleeve 421. The threaded sleeve 421 is rotatably connected to the limiting assembly 423 around the axis of the first shaft segment 21.

[0197] By setting a limiting component 423, and making the limiting component 423 cover the threaded sleeve 421 and rotatably connected to the threaded sleeve 421 around the axis of the first shaft segment 21, the limiting component 423 can further limit the position of the threaded sleeve 421, making the threaded sleeve 421 more stable when rotating around the axis of the first shaft segment 21.

[0198] The limiting component 423 can be implemented in various ways, as long as it can ensure greater stability when the threaded sleeve 421 is rotatably mounted on the housing 1 around the axis of the first shaft segment 21. This embodiment does not limit the specific structure of the limiting component 423. For example, in one possible implementation, see... Figure 5 The limiting assembly 423 includes a first limiting member 4231 and a second limiting member 4232, wherein both the first limiting member 4231 and the second limiting member 4232 are connected to the housing 1 and are covered by the threaded sleeve 421. The threaded sleeve 421 is rotatably connected to the first limiting member 4231 and the second limiting member 4232 respectively around the axial direction of the first shaft segment 21.

[0199] By connecting the first limiting member 4231 and the second limiting member 4232 to the housing 1 and covering the threaded sleeve 421, the threaded sleeve 421 can be limited from various positions as much as possible, thereby making the threaded sleeve 421 more stable when it is rotatably mounted on the housing 1 around the axis of the first shaft segment 21.

[0200] Further reading is available upon request. Figure 5 The first limiting member 4231 and the second limiting member 4232 are located on both sides of the first adjusting gear 4211 along the axial direction of the first shaft segment 21.

[0201] By positioning the first limiting member 4231 and the second limiting member 4232 along the axial direction of the first shaft segment 21 on both sides of the first adjusting gear 4211, the first limiting member 4231 and the second limiting member 4232 can limit the threaded sleeve 421 from both sides of the first adjusting gear 4211, thereby making the threaded sleeve 421 more stable when rotating around the axis of the first shaft segment 21.

[0202] The structures of the first limiting member 4231 and the second limiting member 4232 described above can be varied. Taking the first limiting member 4231 as an example, see [link to example]. Figure 5 The first limiting member 4231 is a retaining ring structure. The retaining ring structure is covered by the threaded sleeve 421 and one end of the retaining ring structure along the circumference of the threaded sleeve 421 is connected to the housing 1, and the other end is a free end. Alternatively, both ends of the retaining ring structure along the circumference of the threaded sleeve 421 are connected to the housing 1.

[0203] When one end of the first limiting member 4231 is connected to the housing 1 along the circumference of the threaded sleeve 421 and the other end is a free end, it makes it more convenient to assemble the first limiting member 4231 to the housing 1.

[0204] When the first limiting member 4231 is connected to both ends of the threaded sleeve 421 around the machine housing 1, the first limiting member 4231 can play a better limiting role on the threaded sleeve 421, thereby making the threaded sleeve 421 more stable when rotating around the axis of the first shaft segment 21.

[0205] Regarding the second limiting member 4232, the structure of the second limiting member 4232 can be similar to that of the first limiting member 4231. Specifically, the second limiting member 4232 is a retaining ring structure. The retaining ring structure is covered by the threaded sleeve 421, and one end of the retaining ring structure along the circumference of the threaded sleeve 421 is connected to the housing 1, while the other end is a free end. Alternatively, both ends of the retaining ring structure along the circumference of the threaded sleeve 421 are connected to the housing 1.

[0206] When the structure of the second limiting member 4232 is similar to that of the first limiting member 4231, the second limiting member 4232 can bring the same or similar beneficial effects as the first limiting member 4231. For details, please refer to the description of the second limiting member 4232 in the above embodiments. This embodiment will not repeat the description here.

[0207] It should be noted that there are multiple ways in which the massage drive 33 can drive the first massage component 31 and / or the second massage component 32 to move. In one possible implementation, the massage drive 33 can be directly connected to the first massage component 31 and / or the second massage component 32 to drive the first massage component 31 and / or the second massage component 32 to move respectively.

[0208] In another possible implementation, the massage drive 33 can indirectly drive the first massage assembly 31 and / or the second massage assembly 32 by driving the movement of other components. Specifically, in some embodiments, see [link to relevant documentation]. Figure 2 The first shaft segment 21 and the second shaft segment 22 are rotatably disposed on the housing 1 around the axis of the first shaft segment 21. The massage drive 33 is used to drive the first shaft segment 21 and / or the second shaft segment 22 to rotate around the axis of the first shaft segment 21, so as to drive the first massage assembly 31 and / or the second massage assembly 32 to move.

[0209] Since the first massage component 31 is sleeved on the first shaft segment 21 and the second massage component 32 is sleeved on the second shaft segment 22, when the massage drive 33 drives the first shaft segment 21 and / or the second shaft segment 22 to rotate around the axis of the first shaft segment 21, it can achieve the purpose of driving the first massage component 31 and / or the second massage component 32 to move.

[0210] In this design, the massage drive 33 indirectly drives the first massage component 31 and / or the second massage component 32 to rotate around the axis of the first shaft segment 21 when driving the first massage component 31 and / or the second massage component 32. This results in a simple structure. As a result, the massage drive 33 does not need to directly drive the first massage component 31 and / or the second massage component 32. This design simplifies the structure of the first massage component 31 and the second massage component 32 to a certain extent, reducing their cost.

[0211] In some embodiments, see Figure 2 and Figure 4The massage mechanism 3 further includes: a transmission assembly 34, a massage drive 33 connected to the transmission assembly 34, the transmission assembly 34 being connected to the first shaft segment 21 and the second shaft segment 22 respectively, the massage drive 33 driving the first shaft segment 21 and the second shaft segment 22 to rotate around the axis of the first shaft segment 21 through the transmission assembly 34, the transmission assembly 34 being configured to remain connected to the first shaft segment 21 when the first shaft segment 21 moves along its own axial direction, and to remain connected to the second shaft segment 22 when the second shaft segment 22 moves along the axial direction of the first shaft segment 21.

[0212] By setting the transmission component 34, the movement of the massage drive component 33 can be synchronously transmitted to the first shaft segment 21 and the second shaft segment 22 through the transmission component 34, thereby synchronously driving the first massage component 31 and the second massage component 32 to move. There is no need to set separate massage drive components 33 for the first massage component 31 and the second massage component 32. 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.

[0213] By configuring the transmission component 34 to remain connected to the first shaft segment 21 when it moves along its own axial direction, and to remain connected to the second shaft segment 22 when it moves along the axial direction of the first shaft segment 21, the action of adjusting the distance between the first massage component 31 and the second massage component 32 and the action of driving the first massage component 31 and the second massage component 32 to move and perform massage can be performed simultaneously. In simple terms, the first massage component 31 and the second massage component 32 can still perform massage without stopping during the process of adjusting the distance between them. Therefore, the user experience of the massage mechanism 100 can be improved to a certain extent.

[0214] There are multiple ways to implement the aforementioned transmission component 34. For one possible implementation, please refer to [link to relevant documentation]. Figure 4 The transmission assembly 34 includes: a first driven gear 341, which is slidable along the axial direction of the first shaft segment 21 and is anti-rotationally sleeved on the first shaft segment 21 so that it remains connected to the first shaft segment 21 when sliding along its own axial direction; and a massage drive 33 is used to drive the first driven gear 341 to rotate and drive the first shaft segment 21 to rotate.

[0215] Since the first driven gear 341 is anti-rotationally sleeved on the first shaft segment 21, when the massage drive 33 drives the first driven gear 341 to rotate, the first driven gear 341 can synchronously drive the first shaft segment 21 to rotate, thereby driving the first massage component 31 to move and achieve the purpose of massage.

[0216] Meanwhile, since the first driven gear 341 is also slidably sleeved on the first shaft segment 21 along the axial direction of the first shaft segment 21, the first driven gear 341 also allows the adjustment drive to drive the first shaft segment 21 to move along the axial direction of the first shaft segment 21 to adjust the distance between the first massage component 31 and the second massage component 32.

[0217] As can be seen, when the transmission component 34 includes a first driven gear 341, and the first driven gear 341 is slidably sleeved on the first shaft segment 21 along the axial direction of the first shaft segment 21 and is set to prevent rotation around the axial direction of the first shaft segment 21, the purpose of massaging through the first massage component 31 and adjusting the distance between the first massage component 31 and the second massage component 32 can be achieved. 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.

[0218] To achieve the purpose of the first driven gear 341 being slidably sleeved on the first shaft segment 21 along the axial direction of the first shaft segment 21 and being anti-rotating about the axial direction of the first shaft segment 21, in some embodiments, see... Figure 4 and Figure 10 , Figure 10 The first shaft segment 21 is provided with a first anti-rotation part 212, and a second anti-rotation part 34111 matching the first anti-rotation part 212 is provided in the mounting hole 3411 of the first driven gear 341. The second anti-rotation part 34111 cooperates with the first anti-rotation part 212 to prevent the first driven gear 341 from rotating relative to the first shaft segment 21 about the axial direction of the first shaft segment 21.

[0219] Since the mounting hole 3411 of the first driven gear 341 is provided with a second anti-rotation part 34111 that matches the first anti-rotation part 212, when the first shaft segment 21 is inserted into the mounting hole 3411, under the cooperation of the first anti-rotation part 212 and the second anti-rotation part 34111, the first shaft segment 21 can only move in the mounting hole 3411 relative to the first driven gear 341 along the axial direction of the first shaft segment 21 and cannot rotate around the axis of the first shaft segment 21 in the mounting hole 3411. Thus, the purpose of driving the first shaft segment 21 to rotate synchronously when the first driven gear 341 rotates can be achieved.

[0220] As can be seen, by cooperating between the first anti-rotation part 212 and the second anti-rotation part 34111, the purpose of preventing the first driven gear 341 and the first shaft segment 21 from rotating around the first shaft segment 21 can be achieved. The structure is simple, and therefore, the cost of the massage mechanism 100 can be reduced to a certain extent.

[0221] There are multiple ways to implement the first anti-rotation part 212 mentioned above. In one possible implementation, see [link to relevant documentation]. Figure 10The first shaft segment 21 has a cutting part, which constitutes the first anti-rotation part 212.

[0222] By making the cutting part on the first shaft segment 21 form the first anti-rotation part 212, the formation of the first anti-rotation part 212 can be very simple, without increasing the cost of manufacturing the first anti-rotation part 212, thereby achieving the goal of reducing the cost of the massage mechanism 100.

[0223] In some embodiments, see Figure 10 and Figure 11 , Figure 11 yes Figure 10 The massage mechanism 100 is shown in a structural schematic diagram from another perspective. The transmission assembly 34 also includes a second driven gear 342 and a transmission shaft 343. The second driven gear 342 is slidable along the axial direction of the second shaft segment 22 and is anti-rotationally sleeved on the second shaft segment 22. The transmission shaft 343 is rotatably mounted on the housing 1 around the axial direction of the first shaft segment 21. A first driving gear 3431 meshing with the first driven gear 341 and a second driving gear 3432 meshing with the second driven gear 342 are sleeved on the transmission shaft 343. The massage drive 33 is used to drive the transmission shaft 343 to rotate, so as to synchronously drive the first driven gear 341 and the second driven gear 342 to rotate.

[0224] Since the transmission shaft 343 is fitted with a first driving gear 3431 that meshes with the first driven gear 341 and a second driving gear 3432 that meshes with the second driven gear 342, when the massage drive 33 drives the transmission shaft 343 to rotate, it can synchronously drive the first driven gear 341 and the second driven gear 342 to rotate.

[0225] Next, since the first driven gear 341 is anti-rotationally sleeved on the first shaft segment 21, when the first driven gear 341 and the second driven gear 342 rotate, they can synchronously drive the first shaft segment 21 and the second shaft segment 22 to move, thereby achieving the purpose of driving the first massage component 31 and the second massage component 32 to move for synchronous massage.

[0226] It can be seen that when the transmission assembly 34 also includes a second driven gear 342 and a transmission shaft 343, the meshing of the first driven gear 341 with the first driving gear 3431 and the meshing of the second driven gear 342 with the second driving gear 3432 can achieve the purpose of transmitting the motion of the massage drive 33 to the first shaft segment 21 and the second shaft segment 22. That is, the motion of the massage drive 33 is transmitted to the first shaft segment 21 and the second shaft segment 22 through gear transmission. The implementation method is simple and reliable. Therefore, the cost of the transmission assembly 34 can be reduced to a certain extent.

[0227] Of course, the transmission component 34 can also be implemented in other possible ways, and this embodiment does not limit it.

[0228] To achieve a more rational spatial arrangement of the transmission assembly 34 within the massage mechanism 100, in some embodiments, see [reference needed]. Figure 11 The transmission assembly 34 further includes a first bevel gear 344 and a second bevel gear 345, wherein the first bevel gear 344 is sleeved on the transmission shaft 343, the second bevel gear 345 meshes with the first bevel gear 344, and the massage drive 33 is used to drive the second bevel gear 345 to rotate, so as to drive the transmission shaft 343 to rotate through the first bevel gear 344.

[0229] When the transmission assembly 34 also includes a first bevel gear 344 and a second bevel gear 345, the arrangement of the massage drive component 33 in the massage mechanism 100 can be changed through the cooperation of the first bevel gear 344 and the second bevel gear 345. In this way, when arranging the massage drive component 33, the position of the massage drive component 33 can be reasonably arranged according to the space of the massage mechanism 100, thereby achieving the purpose of making full use of the space of the massage mechanism 100, and thus achieving the effect of making the structure of the massage mechanism 100 more compact.

[0230] In some embodiments, see Figure 11 The axial direction of the first bevel gear 344 is perpendicular to the axial direction of the second bevel gear 345.

[0231] By making the axial direction of the first bevel gear 344 perpendicular to the axial direction of the second bevel gear 345, the layout of the first bevel gear 344 and the second bevel gear 345 can be made more regular. On the one hand, it is convenient to assemble the first bevel gear 344 and the second bevel gear 345. On the other hand, it can also make the structural layout of the entire massage mechanism 100 more regular, which is convenient for subsequent maintenance.

[0232] Of course, in other embodiments, the axial direction of the first bevel gear 344 may not be perpendicular to the axial direction of the second bevel gear 345, and this embodiment does not limit this.

[0233] In some embodiments, a turbine 3451 coaxial with the second bevel gear 345 is provided on the second bevel gear 345, and a worm 331 is provided on the drive shaft of the massage drive 33, the worm 331 meshing with the turbine 3451.

[0234] Since the worm 331 meshes with the turbine 3451, when the drive shaft of the massage drive 33 starts to rotate, it can drive the worm 331 to rotate, which in turn can drive the turbine 3451 to rotate.

[0235] When the turbine 3451 starts to rotate, since the turbine 3451 is located on the second bevel gear 345 and is coaxial with the second bevel gear 345, it can drive the second bevel gear 345 to rotate.

[0236] As can be seen, the massage drive 33 can transmit its own motion to the second bevel gear 345 through the cooperation of a worm gear. Since the worm gear has the effect of changing the transmission direction, it can make more reasonable use of the space of the massage mechanism 100 to a certain extent, thereby making the structure of the massage mechanism 100 more compact.

[0237] In some embodiments, see Figure 4 and Figure 12 , Figure 12 yes Figure 4 The diagram shows the structure of the first massage component 31. The first massage component 31 includes a motion conversion component 311 and a first massage head 312. The motion conversion component 311 is sleeved on the first shaft segment 21, and the first massage head 312 is connected to the motion conversion component 311. The motion conversion component 311 is used to convert the rotational motion of the first shaft segment 21 into the oscillating motion of the first massage head 312.

[0238] Since the motion conversion component 311 is sleeved on the first shaft segment 21 and the first massage head 312 is connected to the motion conversion component 311, when the first shaft segment 21 starts to rotate, the rotational motion of the first shaft segment 21 can be converted into the oscillating motion of the first massage head 312 under the action of the motion conversion component 311. When the first massage head 312 starts to oscillate, it can knead or pound the area to be massaged, thus improving the massage effect.

[0239] There are multiple ways to implement the motion conversion component 311 described above. In one possible implementation, see [link to relevant documentation]. Figure 3 and Figure 12 The motion conversion component 311 includes a slanted wheel 3111, which is sleeved on the first shaft segment 21. The first massage head 312 is rotatably sleeved on the peripheral wall of the slanted wheel 3111 via a swing arm 3111a around the axis of the slanted wheel 3111.

[0240] Since the first massage head 312 is rotatably mounted on the peripheral wall of the inclined shaft wheel 3111 via the swing arm 3111a around the axis of the inclined shaft wheel 3111, when the inclined shaft wheel 3111 rotates around the axis of the first shaft segment 21, the rotation of the inclined shaft wheel 3111 around the axis of the first shaft segment 21 can be converted into the swing of the swing arm 3111a, which can then drive the first massage head 312 to swing, thereby achieving the purpose of massage through the first massage head 312.

[0241] In other words, when the motion conversion component 311 includes the inclined shaft wheel 3111, the rotational motion of the inclined shaft wheel 3111 can be cleverly converted into the oscillating motion of the first massage head 312. Complex functions can be accomplished with a simple structure. The structural design is very ingenious and can reduce the cost of the motion conversion component 311 to a certain extent.

[0242] In order to better convert the rotational motion of the inclined shaft wheel 3111 into the oscillating motion of the first massage head 312, and to avoid the situation where the swing arm 3111a follows the rotation of the inclined shaft wheel 3111, in some embodiments, see Figure 3 and Figure 12 The housing 1 is provided with a clearance hole 13a, the shape and size of which match the movement trajectory of the swing arm 3111a.

[0243] By providing the clearance hole 13a, on the one hand, the clearance hole 13a can guide the movement of the swing arm 3111a, allowing the swing arm 3111a to swing along the guiding direction of the clearance hole 13a, thereby preventing the clearance hole 13a from rotating with the slant wheel 3111. On the other hand, the clearance hole 13a can also provide clearance space for the swing arm 3111a, preventing interference between the swing arm 3111a and the housing 1.

[0244] To make the rotation of the swing arm 3111a more smooth around the axis of the inclined wheel 3111, in some embodiments, see Figure 12 The inclined shaft wheel 3111 has multiple grooves 31111 on its peripheral wall. The multiple grooves 31111 are spaced apart along the circumference of the inclined shaft wheel 3111, and each groove 31111 extends along the axial direction of the inclined shaft wheel 3111.

[0245] By providing multiple grooves 31111 on the peripheral wall of the inclined shaft wheel 3111, the contact area between the swing arm 3111a and the peripheral wall of the inclined shaft wheel 3111 is smaller when the swing arm 3111a is fitted onto the peripheral wall of the inclined shaft wheel 3111, thereby making the swing arm 3111a rotate more smoothly around the axis of the inclined shaft wheel 3111.

[0246] Since the swing arm 3111a is rotatably sleeved on the peripheral wall of the inclined shaft wheel 3111 around the axis of the inclined shaft wheel 3111, considering that the swing arm 3111a may slip off the peripheral wall of the inclined shaft wheel 3111 during the rotation of the inclined shaft wheel 3111 around the axis of the first shaft segment 21, which would cause the entire massage mechanism 100 to malfunction, in order to avoid this situation, see [reference to previous embodiments]. Figure 12The inclined shaft wheel 3111 has a blocking member 31112, which protrudes radially from the peripheral wall of the inclined shaft wheel 3111. The motion conversion assembly 311 also includes a pressure cover 3112, which is disposed on the inclined shaft wheel 3111. The swing arm 3111a is limited between the pressure cover 3112 and the blocking member 31112.

[0247] By ensuring that both ends of the inclined shaft wheel 3111 have blocking members 31112 along the axial direction of the inclined shaft wheel 3111, and by limiting the swing arm 3111a between the pressure cover 3112 and the blocking members 31112, the swing arm 3111a can be stably fitted onto the peripheral wall of the inclined shaft wheel 3111, thereby preventing the swing arm 3111a from slipping off the peripheral wall of the inclined shaft wheel 3111.

[0248] To facilitate quick and easy assembly during the process of rotatably fitting the swing arm 3111a onto the peripheral wall of the inclined shaft wheel 3111 around its axis, in some embodiments, see [reference needed]. Figure 12 The pressure cap 3112 is detachably mounted on the inclined shaft wheel 3111.

[0249] By detachably mounting the pressure cap 3112 onto the inclined shaft wheel 3111, during the process of rotatably mounting the swing arm 3111a onto the peripheral wall of the inclined shaft wheel 3111 around its axis, the pressure cap 3112 can first be removed from the inclined shaft wheel 3111, and then the swing arm 3111a can be rotatably mounted onto the peripheral wall of the inclined shaft wheel 3111 around its axis. After the swing arm 3111a is rotatably mounted onto the peripheral wall of the inclined shaft wheel 3111, the removed pressure cap 3112 can finally be reconnected to the inclined shaft wheel 3111. In this way, the purpose of blocking the swing arm 3111a between the pressure cap 3112 and the blocking member 31112 can be achieved.

[0250] Obviously, by making the pressure cap 3112 detachably connected to the inclined shaft wheel 3111, it becomes more convenient and faster to rotatably fit the swing arm 3111a around the axis of the inclined shaft wheel 3111 onto the peripheral wall of the inclined shaft wheel 3111.

[0251] The aforementioned pressure cap 3112 can be detachably connected to the inclined shaft wheel 3111 by screws or any other possible means, and this embodiment does not limit this.

[0252] Regarding the second massage component 32, the structure of the second massage component 32 may be the same as or similar to the structure of the first massage component 31 described above. For details, please refer to the description in the above embodiments. This embodiment will not repeat the description here.

[0253] In some embodiments, see Figure 2The housing 1 includes a first housing 14 and a second housing 15, wherein the first housing 14 is detachably fastened to the second housing 15 and together with the second housing 15 form a mounting cavity, and at least part of the structure of the spacing adjustment mechanism 4, the massage mechanism 3 and the mounting shaft 2 are located in the mounting cavity.

[0254] By locating at least a portion of the spacing adjustment mechanism 4, the massage mechanism 3, and the mounting shaft 2 within the mounting cavity, the entire massage mechanism 100 appears cleaner and more aesthetically pleasing. Furthermore, the housing 1 provides protection for these structures, ensuring more stable operation of the massage mechanism 100.

[0255] This application also provides a massage device 1000, see [link]. Figure 13 , Figure 13 This is a schematic diagram of the structure of a massage device 1000 provided in an embodiment of this application. The massage device 1000 includes a massage mechanism 100.

[0256] The structure of the massage mechanism 100 can be the same as that of any of the massage mechanisms 100 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the massage mechanism 100 in the above embodiments. This embodiment will not repeat the description.

[0257] In this embodiment, since the massage mechanism 100 provides ideal massage comfort and is relatively compact, when the massage mechanism 100 is applied to the massage device 1000, it can improve the user experience of the massage device 1000 while reducing its size.

[0258] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
