Description

Technical Field

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

[0002] With the rapid pace of modern life and work, people spend long hours immersed in work or lack sufficient physical activity, leading to muscle tension and poor blood circulation in areas such as the neck, shoulders, waist, and legs. This can result in conditions like frozen shoulder, cervical spondylosis, and lower back and leg pain. Against this backdrop, massage devices, as convenient health aids, are gaining popularity due to their ability to effectively relieve physical fatigue.

[0003] Because different users have different neck and shoulder widths, the technology provides a distance adjustment scheme for the massage components to adapt to different user body shapes. However, users do not feel the distance adjustment operation in progress, which makes it impossible for users to determine whether the distance adjustment is effective, thus causing them to frequently operate the distance adjustment button. Utility Model Content

[0004] This application discloses a massage mechanism and massager that can adjust the spacing between massage components, solving the problem in related technologies where users do not clearly perceive the adjustment of the massage components, which can easily lead to misoperation.

[0005] To achieve the above objectives, embodiments of this application provide a massage mechanism, comprising: a massage mechanism including a first massage component and a second massage component; a rotating shaft, on which the first and second massage components are slidably mounted and spaced apart along the axial direction of the rotating shaft; an adjusting mechanism mounted on the rotating shaft for adjusting the distance between the first and second massage components; and a driving member configured such that: when the driving member drives the rotating shaft to rotate in a first direction, the adjusting mechanism remains stationary, and the first and second massage components swing in a first swing direction; when the driving member drives the rotating shaft to rotate in a second direction, at least a portion of the adjusting mechanism can move axially to adjust the distance between the first and second massage components, and the first and second massage components swing in a second swing direction, the first swing direction being opposite to the second swing direction.

[0006] As an optional implementation, the first massage assembly includes: a first eccentric wheel, sleeved on a rotating shaft and capable of rotating synchronously with the rotating shaft; a second eccentric wheel, sleeved on the rotating shaft and capable of rotating synchronously with the rotating shaft, the second eccentric wheel and the first eccentric wheel being spaced apart axially; and a first massage head, movably sleeved on the rotating shaft, the first massage head being sandwiched between the first eccentric wheel and the second eccentric wheel; when the rotating shaft rotates in a first direction or a second direction, the first eccentric wheel and the second eccentric wheel can rotate with the rotating shaft to drive the first massage head to oscillate.

[0007] As an optional implementation, the massage mechanism further includes a housing for accommodating the adjustment mechanism, which includes a first adjustment component and a second adjustment component. The first and second adjustment components are used to adjust the axial positions of the first and second massage components, respectively. The first adjustment component includes: a base fixed relative to the housing; and an adjustment member movable along the axial direction of a rotation axis to drive the first massage component to move axially. The adjustment member includes an adjustment portion, and the base includes a mating portion, with the adjustment portion and the mating portion slidingly engaged. When the rotation axis rotates in a first direction, the adjustment member remains stationary relative to the base and does not rotate with the rotation axis. When the rotation axis rotates in a second direction, the rotation axis drives the adjustment member to rotate synchronously, and the adjustment portion and the mating portion slidely engage to move the adjustment member away from the base, thereby bringing the first massage component closer to the second massage component.

[0008] As an optional implementation, the massage mechanism further includes: a clutch component, which is sleeved on the rotating shaft; an adjusting component is sleeved outside the clutch component and fixedly connected to the clutch component; the clutch component stops rotating when the rotating shaft rotates in a first direction, and drives the adjusting component to rotate synchronously with the rotating shaft when the rotating shaft rotates in a second direction.

[0009] As an optional implementation, the clutch includes a one-way bearing, which is sleeved on the rotating shaft, and the adjusting element is sleeved on the rotating shaft via the one-way bearing.

[0010] As an optional implementation, the massage mechanism further includes a metal sleeve fitted over the outside of the rotating shaft and connected between the clutch and the rotating shaft.

[0011] As an optional implementation, a first adjusting component is sleeved on the first end of the rotating shaft, the first adjusting component abuts against the first side of the first massage component, and the first side of the first massage component is opposite to the second massage component; a second adjusting component is sleeved on the second end of the rotating shaft, the second adjusting component abuts against the first side of the second massage component, and the first side of the second massage component is opposite to the first massage component; when the driving member drives the rotating shaft to rotate in the second direction, the first adjusting component and the second adjusting component are configured to drive the first massage component and the second massage component to move closer to each other.

[0012] As an optional implementation, the massage mechanism further includes an elastic component for applying a restoring force to the first massage component and the second massage component, distancing them from each other.

[0013] As an optional implementation, the massage mechanism further includes a housing for accommodating the adjustment mechanism. The elastic component includes: a first limiting member fixed to the housing, with a rotating shaft passing through the first limiting member; a first elastic member sleeved on the rotating shaft, with both ends of the first elastic member abutting against the first limiting member and the first massage component, respectively; a second limiting member fixed to the housing, with the rotating shaft passing through the second limiting member; and a second elastic member sleeved on the rotating shaft, with both ends of the second elastic member abutting against the second limiting member and the second massage component, respectively.

[0014] As an optional implementation, the adjusting part and the mating part cooperate to form multiple adjusting positions; when the rotating shaft rotates in the second direction, the adjusting member slides relative to the base, and the adjusting part is in different adjusting positions relative to the mating part, so that when the adjusting member and the base are in different adjusting positions, the axial distance between the adjusting part and the mating part is different, so as to adjust the distance between the first massage assembly and the second massage assembly.

[0015] As an optional implementation, the adjusting part includes a plurality of adjusting teeth arranged circumferentially along the rotation axis. The adjusting part includes a first end face away from the base. Along a second direction, the distance from the tooth tip of the plurality of adjusting teeth to the first end face gradually decreases. The mating part includes a plurality of mating teeth arranged circumferentially along the rotation axis. When one adjusting tooth mates with multiple different mating teeth, multiple adjusting positions can be formed. The base includes a second end face away from the adjusting part. Along a second direction, the distance from the tooth tip of the plurality of mating teeth to the second end face gradually increases. The mating teeth are adapted to the adjusting teeth, and the number of mating teeth, the number of adjusting teeth, and the number of adjusting positions are the same.

[0016] As an optional implementation, each adjusting tooth includes an adjusting tooth surface, the axial distance between the two ends of the adjusting tooth surface of each adjusting tooth is the adjusting tooth height, and the adjusting tooth heights of two adjacent adjusting teeth are the same; and each mating tooth includes a mating tooth surface, the axial distance between the two ends of the mating tooth surface of each mating tooth is the mating tooth height, and the mating tooth heights of two adjacent mating teeth are the same.

[0017] As an optional implementation, the adjusting part includes a first limiting surface extending axially along the rotation shaft, the first limiting surface being connected to the adjusting tooth surface of the first adjusting tooth, the first adjusting tooth being the adjusting tooth furthest from the first end face; the mating part includes a second limiting surface extending axially along the rotation shaft, the second limiting surface being connected to the mating tooth surface of the first mating tooth, the first mating tooth being the mating tooth furthest from the second end face; when the rotation shaft rotates in the first direction, the first limiting surface and the second limiting surface mutually limit each other to prevent the adjusting member from rotating relative to the base.

[0018] As an optional implementation, the base includes two mating parts, which are symmetrically arranged with respect to the axis of rotation; the adjusting member includes two adjusting parts, which are symmetrically arranged with respect to the axis of rotation.

[0019] As an optional implementation, the adjusting member includes a support portion, two adjusting portions are disposed on the outer periphery of the support portion, at least a portion of the support portion is exposed outward along the axial direction of the rotation axis, and the mating portion at least partially covers the support portion.

[0020] As an optional implementation, the massage mechanism further includes: a gear set, which is connected to the output shaft of the drive component, the output shaft of the drive component being perpendicular to the axis of the rotating shaft; and a bevel gear assembly, which is sleeved on the rotating shaft and connected to the gear set.

[0021] As an optional implementation, the first adjustment component and the second adjustment component are symmetrically arranged, as are the first massage component and the second massage component.

[0022] A second aspect of this application provides a massager including a massage mechanism.

[0023] Compared with the prior art, the beneficial effects of this application are:

[0024] When the rotating shaft switches from rotating in the first direction to rotating in the second direction to adjust the distance of the massage components, the swing direction of the first and second massage components changes. Users wearing the massager can clearly perceive that the massager is adjusting the distance, preventing them from frequently pressing buttons due to not noticing the change in the distance between the first and second massage components. Simultaneously, while adjusting the distance between the first and second massage components, the swing of the components remains unaffected, ensuring the kneading action continues, thus improving the user experience.

Detailed Implementation

[0039] 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.

[0040] In this application, the terms "upper," "lower," "top," "bottom," "inner," etc., 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] With the ever-evolving fast pace and high-pressure environment of modern life, people's work and lifestyles have undergone profound changes. Prolonged sitting at a desk or focusing on electronic screens has become the norm for many. Maintaining the same posture for extended periods, coupled with a lack of necessary physical activity, leads to the gradual accumulation of muscle tension and stiffness in key weight-bearing and frequently moving areas such as the neck, shoulders, lower back, and legs. This hinders blood circulation and exacerbates problems like insufficient local nutrient supply and the accumulation of metabolic waste. Over time, this can gradually evolve into more serious health problems, such as chronic pain from frozen shoulder, degenerative changes in the cervical spine due to cervical spondylosis, and lower back and leg pain, severely impacting people's quality of life.

[0045] Massagers effectively relieve muscle tension, promote blood circulation, and accelerate the excretion of metabolic waste by simulating manual massage techniques such as kneading, tapping, and vibration, thereby helping users restore physical vitality and reduce fatigue.

[0046] Because different users have varying neck and shoulder widths, related technologies offer adjustable massage component distances to accommodate different body types. Due to space limitations in massagers, the adjustment range of the massage components is often set within a relatively compact area to ensure structural integrity. However, in these technologies, the user's perception of the ongoing adjustment is not readily apparent, leading to uncertainty about whether the adjustment is effective and resulting in frequent button presses.

[0047] To address the aforementioned issues, the inventors investigated the limitations of existing massage devices and improved the existing massage mechanism by designing a massage mechanism in which the massage direction is opposite when the massage interval is adjusted to the direction when no adjustment is needed, thereby enhancing the user experience.

[0048] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0049] Please see Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of the massage mechanism 100 provided in the embodiments of this application. Figure 2 This is a second schematic diagram of the structure of the massage mechanism 100 provided in this application embodiment. This application embodiment discloses a massage mechanism 100, comprising: a massage mechanism 10, which includes a first massage component 101 and a second massage component 102; a rotating shaft 20, on which the first massage component 101 and the second massage component 102 are slidably mounted and spaced apart along the axial direction of the rotating shaft 20; and a distance adjustment mechanism 30, mounted on the rotating shaft 20, used to adjust the distance between the first massage component 101 and the second massage component 102.

[0050] The drive member 50 is configured such that when the drive member 50 drives the rotating shaft 20 to rotate in a first direction, the adjusting mechanism 30 remains stationary, and the first massage assembly 101 and the second massage assembly 102 swing in a first swing direction; when the drive member 50 drives the rotating shaft 20 to rotate in a second direction, at least a portion of the adjusting mechanism 30 can move axially to adjust the distance between the first massage assembly 101 and the second massage assembly 102, and the first massage assembly 101 and the second massage assembly 102 swing in a second swing direction, the first swing direction being opposite to the second swing direction.

[0051] The massage mechanism 10 of the massage core 100 includes a first massage component 101 and a second massage component 102, which can simultaneously massage the left and right shoulders and neck of the user.

[0052] When the first massage component 101 and the second massage component 102 work simultaneously, they can form complex massage movements similar to human hand kneading, which not only enhances the intensity and depth of the massage, but also makes the massage process more natural and smooth.

[0053] Optionally, the first massage component 101 and the second massage component 102 can perform massage by swinging or rotating, or by vibrating or tapping, and can also add functions such as hot compress or magnetic therapy to improve the massage effect.

[0054] The massage mechanism 100 also includes a rotating shaft 20. The first massage component 101 and the second massage component 102 are slidably sleeved on the rotating shaft 20 and are spaced apart along the axial direction of the rotating shaft 20. Both the first massage component 101 and the second massage component 102 are movable along the axial direction of the rotating shaft 20, so that the distance between the first massage component 101 and the second massage component 102 changes.

[0055] When the rotating shaft 20 rotates, a portion of the first massage assembly 101 and the second massage assembly 102 can rotate along with the rotation of the rotating shaft 20, thereby enabling the massage heads on the first massage assembly 101 and the second massage assembly 102 to oscillate and knead the user's shoulders.

[0056] At the same time, the rotating shaft 20 can also support the first massage component 101 and the second massage component 102, preventing the first massage component 101 and the second massage component 102 from shaking due to the reaction force during operation, thus affecting the massage effect.

[0057] The first massage component 101 and the second massage component 102 share a single rotating shaft 20. The rotating shaft 20 can provide structural support for the first massage component 101 and the second massage component 102, and it can also provide power for the swinging of the first massage component 101 and the second massage component 102. The single rotating shaft 20 can make reasonable use of the internal space of the massage mechanism 100 to ensure the structural compactness of the massage mechanism 100.

[0058] The adjusting mechanism 30 is sleeved on the rotating shaft 20. The adjusting mechanism 30 is axially located outside the first massage component 101 and the second massage component 102. When the driving member 50 drives the rotating shaft 20 to rotate in the second direction, at least a part of the adjusting mechanism 30 can move axially to push the first massage component 101 and the second massage component 102 to move inward, thereby adjusting the axial distance between the first massage component 101 and the second massage component 102 to achieve adjustment of the massage distance and improve the applicability and comfort of the massage mechanism 100.

[0059] It is understood that when the rotating shaft 20 rotates in the second direction, the rotating shaft 20 can drive at least a portion of the adjusting mechanism 30 to move, thereby causing the adjusting mechanism 30 to push the first massage component 101 and the second massage component 102 to move axially. Specifically, when the adjusting mechanism 30 pushes the first massage component 101, the first massage component 101 moves towards the second massage component 102 along the rotating shaft 20. When the adjusting mechanism 30 pushes the second massage component 102, the second massage component 102 moves towards the first massage component 101 along the rotating shaft 20, thereby enabling the first massage component 101 and the second massage component 102 to approach each other axially, so as to realize the adjustment of the distance between the adjusting mechanism 30 and the massage mechanism 10.

[0060] The drive unit 50 can be used to drive the rotating shaft 20 to rotate, thereby driving the massage mechanism 10 to move, so as to drive the first massage component 101 and the second massage component 102 to swing or rotate, so as to achieve the massage effect.

[0061] The drive member 50 can be used to drive the adjustment mechanism 30 to move, so that the adjustment mechanism 30 can push the first massage component 101 and the second massage component 102 to move axially under the drive of the drive member 50, so as to adjust the distance between the first massage component 101 and the second massage component 102.

[0062] The drive unit 50 can be used to drive the first massage component 101 and the second massage component 102 to swing, and at the same time, it can drive the distance adjustment mechanism 30 to adjust the distance between the first massage component 101 and the second massage component 102, so that the driving of the massage mechanism 10 and the distance adjustment mechanism 30 can be achieved by a single drive unit 50. This not only reduces the cost of the massage mechanism 100, but also makes the massage mechanism 100 more compact.

[0063] In some embodiments, the drive member 50 may be located in the middle region of the massage mechanism 100, which can make reasonable use of the space between the first massage component 101 and the second massage component 102 and optimize the structural layout of the massage mechanism 100.

[0064] Optionally, the driving component 50 may be a drive motor or other components capable of driving the massage mechanism 10 and / or the adjustment mechanism 30. This embodiment does not limit this.

[0065] The driving component 50 can drive the rotating shaft 20 to rotate in a first direction and in a second direction. When the driving component 50 drives the rotating shaft 20 to rotate in the first direction, the rotating shaft 20 does not drive the adjusting mechanism 30 to move, that is, the adjusting mechanism 30 does not rotate with the rotating shaft 20, the axial distance between the first massage component 101 and the second massage component 102 remains unchanged, and the first massage component 101 and the second massage component 102 swing in the first swing direction to perform massage operation.

[0066] When the drive member 50 drives the rotating shaft 20 to rotate in the second direction, at least a portion of the adjusting mechanism 30 can move axially to adjust the distance between the first massage assembly 101 and the second massage assembly 102. At the same time, the first massage assembly 101 and the second massage assembly 102 swing in the second swing direction to perform massage. The first swing direction is opposite to the second swing direction.

[0067] Thus, when the rotating shaft 20 switches from rotating in the first direction to rotating in the second direction to adjust the distance of the adjusting component, the swing direction of the first massage component 101 and the second massage component 102 changes. The user wearing the massager can clearly perceive that the massager is adjusting the distance, preventing them from frequently pressing buttons because they are unaware of the change in the distance between the first massage component 101 and the second massage component 102. Simultaneously, when the adjusting component is adjusting the distance between the first massage component 101 and the second massage component 102, it does not affect the swing of the first massage component 101 and the second massage component 102; the kneading action remains continuous, thereby improving the user experience.

[0068] Please see Figure 2In some embodiments, the first massage assembly 101 includes: a first eccentric wheel 1011, sleeved on the rotating shaft 20 and capable of rotating synchronously with the rotating shaft 20; a second eccentric wheel 1013, sleeved on the rotating shaft 20 and capable of rotating synchronously with the rotating shaft 20, the second eccentric wheel 1013 and the first eccentric wheel 1011 being spaced apart axially; and a first massage head 1012, movably sleeved on the rotating shaft 20, the first massage head 1012 being sandwiched between the first eccentric wheel 1011 and the second eccentric wheel 1013; when the rotating shaft 20 rotates in a first direction or a second direction, the first eccentric wheel 1011 and the second eccentric wheel 1013 can rotate with the rotating shaft 20 to drive the first massage head 1012 to swing.

[0069] The first eccentric wheel 1011 and the second eccentric wheel 1013 are engaged with the rotating shaft 20 to limit their movement, thereby enabling the first eccentric wheel 1011 and the second eccentric wheel 1013 to rotate synchronously with the rotating shaft 20. The first eccentric wheel 1011 and the second eccentric wheel 1013 have inclined surfaces, and the first massage head 1012 is sandwiched between the first eccentric wheel 1011 and the second eccentric wheel 1013. When the rotating shaft 20 rotates in the first direction, the first eccentric wheel 1011 and the second eccentric wheel 1013 rotate in the first direction, and the inclined surfaces of the first eccentric wheel 1011 and the second eccentric wheel 1013 can push the first massage head 1012 sandwiched in the middle to swing in the first swing direction.

[0070] It can be understood that when the rotating shaft 20 rotates in the second direction, the first eccentric wheel 1011 and the second eccentric wheel 1013 rotate in the second direction, thereby causing the inclined surfaces of the first eccentric wheel 1011 and the second eccentric wheel 1013 to push the first massage head 1012 clamped therein to swing in the second swing direction.

[0071] It is understood that when the first massage component 101 swings along the first direction, the first massage head 1012 forms a preset path. When the first massage component 101 swings along the second direction, the first massage head 1012 can move in the opposite direction along the preset path, so that the user can clearly feel that the massage mechanism 100 is performing a distance adjustment operation.

[0072] Please see Figure 3 and Figure 4 , Figure 3 This is the third schematic diagram of the structure of the massage mechanism 100 provided in the embodiments of this application. Figure 4 for Figure 3A cross-sectional view along the AA direction. In some embodiments, the massage mechanism 100 further includes a housing 60 for accommodating the adjustment mechanism 30. As a basic component of the massage mechanism 100, the housing 60 protects other internal components from dust, moisture, and other contaminants, thereby protecting the massage mechanism 100 from damage and extending its service life. Simultaneously, the housing 60 provides support and fixation for some internal components of the massage mechanism 100.

[0073] Optionally, the housing 60 may include a first housing 601 and a second housing 602, which are detachable to facilitate the replacement and maintenance of internal components of the massage mechanism 100.

[0074] The adjustment mechanism 30 includes a first adjustment component 31 and a second adjustment component 32, which are used to adjust the axial positions of the first massage component 101 and the second massage component 102, respectively.

[0075] It should be noted that the first massage component 101 and the second massage component 102 have the same structure and working principle, and the first adjustment component 31 and the second adjustment component 32 can have the same structure and working principle. The following mainly describes and introduces the first massage component 101 and the first adjustment component 31, and will not elaborate on the structure and working principle of the second massage component 102 and the second adjustment component 32.

[0076] The first adjusting assembly 31 includes a base 311, which is fixed relative to the housing 60. The base 311 is fixed relative to the housing 60 to provide structural support for the sliding of the adjusting member 312, so that the adjusting member 312, which slides with the base 311, can move away from the base 311 when the rotating shaft 20 rotates.

[0077] Furthermore, the base 311 may include a slot 60a, through which the base 311 is limited to the housing 60 to be fixed relative to the housing 60.

[0078] The first adjustment component 31 also includes an adjustment member 312, which can move along the axial direction of the rotation shaft 20 to drive the first massage component 101 to move along the axial direction. The adjustment member 312 includes an adjustment part 3121, and the base 311 includes a mating part 3111. The adjustment part 3121 and the mating part 3111 slide together.

[0079] When the rotating shaft 20 rotates in the first direction, the adjusting member 312 does not rotate with the rotating shaft 20. The adjusting member 312 remains stationary relative to the base 311, so that the distance between the first massage assembly 101 and the second massage assembly 102 remains unchanged. The first massage assembly 101 and the second massage assembly 102 only perform massage actions in the first swing direction.

[0080] When the rotating shaft 20 rotates in the second direction, the rotating shaft 20 drives the adjusting member 312 to rotate synchronously in the second direction. The adjusting part 3121 and the mating part 3111 slide to make the adjusting member 312 move away from the base 311 in the axial direction, so that the first massage component 101 moves closer to the second massage component 102. At this time, the first massage component 101 and the second massage component 102 move closer to each other and massage in the second swing direction. That is, when the adjusting mechanism 30 adjusts the distance, it does not affect the massage action of the massage mechanism 10.

[0081] like Figure 4 As shown, in some embodiments, the massage mechanism 100 further includes: a clutch 70, which is sleeved on the rotating shaft 20, and an adjusting member 312 which is sleeved outside the clutch 70 and fixedly connected to the clutch 70. The clutch 70 stops rotating when the rotating shaft 20 rotates in a first direction, and drives the adjusting member 312 to rotate synchronously with the rotating shaft 20 when the rotating shaft 20 rotates in a second direction.

[0082] When the rotating shaft 20 rotates in the second direction, the rotating shaft 20 drives the clutch 70 to rotate, thereby causing the clutch 70 to drive the adjusting member 312 to move, and the adjusting member 312 adjusts the distance between the first massage component 101 and the second massage component 102.

[0083] When the rotating shaft 20 rotates in the first direction, it rotates in the first direction but does not drive the clutch 70 to rotate, thereby preventing the adjusting member 312 from rotating in the first direction and keeping the adjusting member 312 stationary relative to the base 311, so that the first massage assembly 101 is not adjusted.

[0084] It is understood that the first massage component 101 only adjusts its distance when the rotating shaft 20 rotates in the second direction. At this time, the rotating shaft 20 drives the adjusting component 312 to adjust the distance, and simultaneously drives the first massage component 101 to oscillate and massage. When the first massage component 101 and the second massage component 102 do not need to adjust their distance, the rotating shaft 20 rotates in the first direction. At this time, the user does not have a need to adjust the distance of the massage components, and the first massage component 101 and the second massage component 102 can meet the user's massage needs simply by performing kneading movements.

[0085] The clutch 70 ensures that during the massage process when the rotating shaft 20 rotates in the first direction, the rotating shaft 20 will not drive the adjusting member 312 to rotate. That is, there will be no change in the distance between the first massage component 101 and the second massage component 102, which ensures the stability of the distance between the first massage component 101 and the second massage component 102 and improves the stability of the massage process.

[0086] During the rotation of the rotating shaft 20 in the second direction, the first massage component 101 and the second massage component 102 swing along the second swing direction. At the same time, the clutch 70 drives the adjusting component 312 to rotate along the second direction, thereby adjusting the distance of the first massage component 101 and the second massage component 102.

[0087] In some embodiments, the clutch 70 includes a one-way bearing, which is sleeved on the rotating shaft 20, and the adjusting member 312 is sleeved on the rotating shaft 20 via the one-way bearing.

[0088] Using a one-way bearing enables the engagement and disengagement of the adjusting element 312 and the rotating shaft 20, allowing the adjusting element 312 to move only when the rotating shaft 20 rotates in the second direction. The one-way bearing has a simple structure, which helps to make reasonable use of the internal space of the massage mechanism 100, thus enabling the massage mechanism 100 to be miniaturized.

[0089] Please see Figure 4 In some embodiments, the massage mechanism 100 further includes a metal sleeve 701, which is sleeved on the outside of the rotating shaft 20 and connected between the clutch 70 and the rotating shaft 20.

[0090] The metal sleeve 701 effectively prevents the clutch 70 from shifting away from the rotating shaft 20 when subjected to external force. During the use of the massager, especially when the user applies pressure or makes dynamic adjustments, shifting of the clutch 70 may cause changes in the adjusted massage interval, thereby affecting the massage effect and user experience.

[0091] Secondly, the use of the metal sleeve 701 also helps to achieve the goal of miniaturization of the massager. The metal sleeve 701 allows the clutch 70 and the rotating shaft 20 to adopt a more compact design.

[0092] In some embodiments, the first adjustment component 31 is sleeved on the first end of the rotating shaft 20, the first adjustment component 31 abuts against the first side of the first massage component 101, and the first side of the first massage component 101 is away from the second massage component 102.

[0093] The first adjusting component 31 is sleeved on the first end of the rotating shaft 20, and at least a portion of the first adjusting component 31 can move under the drive of the rotating shaft 20. Specifically, when the rotating shaft 20 rotates in the second direction under the drive of the drive member 50, it can drive at least a portion of the first adjusting component 31 to move. Through the contact between the first adjusting component 31 and the first massage component 101, the first adjusting component 31 can push the first massage component 101 to move closer to the second massage component 102.

[0094] In some embodiments, the adjusting mechanism 30 further includes a second adjusting component 32, which is sleeved on the second end of the rotating shaft 20. The second adjusting component 32 abuts against the first side of the second massage component 102, and the first side of the second massage component 102 is away from the first massage component 101.

[0095] The second adjusting component 32 is sleeved on the first end of the rotating shaft 20, and at least a portion of the second adjusting component 32 can move under the drive of the rotating shaft 20. Specifically, when the rotating shaft 20 rotates in the second direction under the drive of the drive member 50, it can drive at least a portion of the second adjusting component 32 to move. Through the contact between the second adjusting component 32 and the second massage component 102, the second adjusting component 32 can push the second massage component 102 to move closer to the first massage component 101.

[0096] It can be understood that when the drive member 50 drives the rotating shaft 20 to rotate in the second direction, the rotating shaft 20 drives the first adjusting component 31 and the second adjusting component 32 to move, thereby pushing the first massage component 101 and the second massage component 102 closer to each other, so as to adjust the distance between the first massage component 101 and the second massage component 102.

[0097] Please see Figure 5 , Figure 5 This is an exploded view of the adjusting mechanism 30 provided in an embodiment of this application. In some embodiments, the massage mechanism 100 further includes an elastic component 40, which is used to apply a resetting force to the first massage component 101 and the second massage component 102 to move them away from each other.

[0098] As the first massage assembly 101 and the second massage assembly 102 approach each other axially, they compress the elastic component 40 located between them, causing the elastic component 40 to deform. When the first massage assembly 101 and the second massage assembly 102 approach each other to their limit position, the deformation of the elastic component 40 is converted into a restoring force, which pushes the first massage assembly 101 and the second massage assembly 102 back to their initial position for the next adjustment operation.

[0099] Meanwhile, as the first massage component 101 and the second massage component 102 approach each other along the axial direction, the elastic component 40 can provide a force to the first massage component 101. This force is opposite to the pushing force provided by the first adjustment component 31 to the first massage component 101. After the first adjustment component 31 pushes the first massage component 101 to reach the massage interval required by the user, the first massage component 101 can remain in its current position under the opposite forces applied by the elastic component 40 and the first adjustment component 31 to ensure the effect of the adjustment.

[0100] Similarly, as the first massage component 101 and the second massage component 102 approach each other along the axial direction, the elastic component 40 can provide a force to the second massage component 102, which is opposite to the pushing force provided by the second adjustment component 32 to the second massage component 102. After the second adjustment component 32 pushes the second massage component 102 to reach the massage interval required by the user, the second massage component 102 can remain in the current position under the opposite forces applied by the elastic component 40 and the second adjustment component 32 to ensure the effect of the adjustment.

[0101] In addition, the elastic component 40 also has a buffering effect. During the process of the first massage component 101 and the second massage component 102 approaching each other along the axial direction, the elastic component 40 can prevent the first massage component 101 and the second massage component 102 from approaching each other too quickly, which would make it difficult for the user to control the first massage component 101 and the second massage component 102 to stop in the appropriate position, thereby ensuring the accuracy of the distance adjustment and the user's experience.

[0102] Optionally, the elastic component 40 can be a spring or an elastic washer, which can generate a restoring force. This embodiment does not limit this.

[0103] Please see the return Figure 2 In some embodiments, the massage mechanism 100 further includes a housing 60 for accommodating the adjustment mechanism 30, and the elastic component 40 includes a first limiting member 41, which is fixed to the housing 60, and a rotating shaft 20 passing through the first limiting member 41.

[0104] The first limiting member 41 is fixed to the housing 60, and the rotating shaft 20 passes through the first limiting member 41. The first limiting member 41 and the rotating shaft 20 are movably connected, thereby ensuring that when the rotating shaft 20 rotates, the first limiting member 41 will not rotate with the rotating shaft 20 or move along the axial direction. At the same time, the first limiting member 41 will not hinder the rotation of the rotating shaft 20.

[0105] The elastic component 40 also includes a first elastic element 42, which is sleeved on the rotating shaft 20. The two ends of the first elastic element 42 abut against the first limiting element 41 and the first massage component 101, respectively.

[0106] The first elastic element 42 abuts against the first limiting element 41 and the first massage component 101. When the first massage component 101 approaches the second massage component 102, the first elastic element 42, located between the first limiting element 41 and the first massage component 101, can be compressed and deformed due to the fixed position of the first limiting element 41. When the first massage component 101 moves axially towards its limit position towards the second massage component 102, the deformation generated by the first elastic element 42 is converted into a restoring force that pushes the first massage component 101 away from the second massage component 102, thereby returning the first massage component 101 to its initial position before adjustment.

[0107] The elastic component 40 also includes a second limiting member 43, which is fixed to the housing 60. The rotating shaft 20 passes through the second limiting member 43 and is movably connected to the rotating shaft 20, thereby ensuring that when the rotating shaft 20 rotates, the second limiting member 43 will not rotate with the rotating shaft 20 or move along the axial direction. At the same time, the second limiting member 43 will not hinder the rotation of the rotating shaft 20.

[0108] The elastic component 40 also includes a second elastic element 44, which is sleeved on the rotating shaft 20. The two ends of the second elastic element 44 abut against the second limiting element 43 and the second massage component 102, respectively.

[0109] Similarly, the second elastic member 44 abuts against the second limiting member 43 and the second massage assembly 102. When the second massage assembly 102 approaches the first massage assembly 101, the second elastic member 44, located between the second limiting member 43 and the second massage assembly 102, can be compressed and deformed due to the fixed position of the second limiting member 43. When the second massage assembly 102 moves axially towards its limit position towards the first massage assembly 101, the deformation generated by the second elastic member 44 is converted into a restoring force that pushes the second massage assembly 102 away from the first massage assembly 101, thereby returning the second massage assembly 102 to its initial position before adjustment.

[0110] Specifically, the first elastic element 42 and the second elastic element 44 can be springs. Using springs as the first elastic element 42 and the second elastic element 44 has the advantages of simple structure, ease of manufacturing, and maintenance. Furthermore, the spring performance can be adjusted according to specific design requirements to adapt to different working conditions. By rationally designing the relevant performance of the springs, the reset accuracy and stability of the adjusting mechanism 30 can be guaranteed, thereby improving the overall performance of the massage mechanism 100 and the user experience.

[0111] Please see Figures 6 to 9 , Figure 6 This is one of the structural schematic diagrams of the adjusting member 312 provided in the embodiments of this application. Figure 7This is the second schematic diagram of the structure of the adjusting member 312 provided in the embodiments of this application. Figure 8 This is one of the structural schematic diagrams of the base 311 provided in the embodiments of this application. Figure 9 This is a second schematic diagram of the structure of the base 311 provided in an embodiment of this application. In some embodiments, the adjusting part 3121 and the mating part 3111 cooperate to form multiple adjusting positions; when the rotating shaft 20 rotates in the second direction, the adjusting part 312 slides relative to the base 311, and the adjusting part 3121 is in different adjusting positions relative to the mating part 3111, so that the axial distance between the adjusting part 3121 and the mating part 3111 is different, so as to adjust the distance between the first massage component 101 and the second massage component 102.

[0112] When the rotating shaft 20 rotates in the second direction, the rotating shaft 20 drives the adjusting member 312 to rotate synchronously. The adjusting part 3121 and the mating part 3111 slide to increase the axial distance between the adjusting member 312 and the base 311, thereby bringing the first massage assembly 101 closer to the second massage assembly 102.

[0113] When the rotating shaft 20 rotates in the first direction, the adjusting member 312 does not rotate with the rotating shaft 20. That is, when the rotating shaft 20 rotates in the first direction, the adjusting member 312 no longer pushes the adjusting member 312 to move in a direction away from the base 311.

[0114] The adjusting part 3121 and the mating part 3111 are in sliding engagement. When the adjusting part 312 rotates with the rotating shaft 20, the two surfaces of the adjusting part 3121 and the mating part 3111 that abut against each other slide relative to each other. The frictional force generated by the relative rotation of the adjusting part 3121 and the mating part 3111 is converted into an axial thrust on the adjusting part 3121 by the inclined surface of the mating part, thereby pushing the adjusting part 312 to move axially, so as to drive the first massage component 101 to move axially towards the second massage component 102, thereby achieving the purpose of adjusting the distance between the first massage component 101 and the second massage component 102.

[0115] Please see Figures 6 to 9 In some embodiments, as an optional implementation, the adjusting part 3121 includes a plurality of adjusting teeth 3122 arranged circumferentially along the rotation axis 20. The adjusting part 3121 includes a first end face 3128 opposite to the base 311. Along the second direction, the distance from the tooth tip of the plurality of adjusting teeth 3122 to the first end face 3128 gradually decreases. The mating part 3111 includes a plurality of mating teeth 3112 arranged circumferentially along the rotation axis 20. When one adjusting tooth 3122 is mated with a plurality of different mating teeth 3112, a plurality of adjusting positions can be formed. The base 311 includes a second end face 3114 opposite to the adjusting part 3121. Along the second direction, the distance from the tooth tip of the plurality of mating teeth 3112 to the second end face 3114 gradually increases.

[0116] Among them, the mating teeth 3112 are adapted to the adjusting teeth 3122, and the number of mating teeth 3112 is the same as the number of adjusting teeth 3122.

[0117] When the rotating shaft 20 rotates in the second direction, an adjusting tooth 3122 can slide relative to a mating tooth 3112 in the second direction and mesh with the next mating tooth 3112, thereby completing a gear adjustment. The rotating shaft 20 continues to rotate in the second direction, so that the adjusting tooth 3122 meshes with multiple mating teeth 3112 respectively, thereby completing the switching of various gears.

[0118] Furthermore, when adjusting the distance between the first massage component 101 and the second massage component 102, when the user wishes to stop adjusting the distance at a suitable target level, the angle sensor configured in the massage mechanism 100 can obtain the current rotation angle of the adjusting member 312, so that the rotating shaft 20 rotates in the first direction at a suitable rotation angle, so as to stop the adjusting member 312 at the position where the mating teeth 3112 and the adjusting teeth 3122 corresponding to the target level are engaged with each other. The adjusting teeth 3122 and the mating teeth 3112 are engaged and locked together to form a limiting fit.

[0119] Meanwhile, the first elastic member 42 can apply a pushing force to the first massage component 101 that is away from the second massage component 102, thereby further ensuring that the adjusting member 312 is fixed relative to the base 311 so that the first massage component 101 no longer moves at the current setting.

[0120] It is understandable that, as the distance between the tooth tip of the mating tooth 3112 and the base 311 gradually increases, when the adjusting member 312 rotates in the second direction, one adjusting tooth 3122 can slide along the adjacent mating tooth 3112 in sequence, thereby causing the adjusting member 312 to gradually move away from the base 311.

[0121] Thus, the massager using the massage mechanism 100 can have multiple levels for selecting the distance between the first massage component 101 and the second massage component 102, and the level can be switched by rotating the rotating shaft 20 in the second direction, so that the massager can adapt to users of various body types, thereby improving the user experience.

[0122] In some embodiments, when the rotating shaft 20 rotates along the first direction, the adjusting member 312 does not rotate with the rotating shaft 20, and the adjusting tooth 3122 engages with a mating tooth 3112. At this time, the adjusting tooth 3122 and the mating tooth 3112 interact to ensure that there is no relative movement between the adjusting member 312 and the base 311, thereby ensuring that the axial distance between the adjusting member 312 and the base 311 remains unchanged, so that the distance between the first massage assembly 101 and the second massage assembly 102 remains unchanged.

[0123] When the rotating shaft 20 rotates in the second direction, the adjusting member 312 rotates synchronously with the rotating shaft 20. The adjusting tooth 3122 slides and engages with multiple mating teeth 3112 in sequence, and the adjusting member 312 moves away from the base 311 axially. At this time, the first massage assembly 101 and the second massage assembly 102 swing in the second swing direction, and the adjusting tooth 3122 slides and engages with multiple mating teeth 3112 in sequence in the second direction, thereby switching the axial distance between the adjusting member 312 and the base 311 between different gears, thereby achieving the purpose of adjusting the distance between the first massage assembly 101 and the second massage assembly 102.

[0124] In some embodiments, each adjusting tooth 3122 includes an adjusting tooth surface 3123, the axial distance between the two ends of the adjusting tooth surface 3123 of each adjusting tooth 3122 is the adjusting tooth height, and the adjusting tooth heights of two adjacent adjusting teeth 3122 are the same; and each mating tooth 3112 includes a mating tooth surface 3113, the axial distance between the two ends of the mating tooth surface 3113 of each mating tooth 3112 is the mating tooth height, and the mating tooth heights of two adjacent mating teeth 3112 are the same.

[0125] The axial distance between the two ends of each adjusting tooth surface 3123 is equal to the tooth height of the adjusting tooth 3122, and the tooth heights of each adjusting tooth 3122 are equal. Correspondingly, the axial distance between the two ends of each mating tooth surface 3113 is equal to the tooth height of the mating tooth 3112, and the tooth heights of each mating tooth 3112 are equal.

[0126] In this way, the adjustment tooth heights of two adjacent adjustment teeth 3122 are the same, ensuring that the adjustment amount of each gear is equal when adjusting the distance between the first massage component 101 and the second massage component 102, so that the user can obtain a stable and predictable adjustment effect, thereby improving the efficiency of adjusting the distance between the first massage component 101 and the second massage component 102.

[0127] Please see Figures 6 to 9 In some embodiments, the adjusting part 3121 includes a first limiting surface 3127 extending axially along the rotation shaft 20, the first limiting surface 3127 being connected to the adjusting tooth surface 3123 of the first adjusting tooth 3122a, the first adjusting tooth 3122a being the adjusting tooth 3122 furthest from the first end face 3128; the mating part 3111 includes a second limiting surface 3115 extending axially along the rotation shaft 20, the second limiting surface 3115 being connected to the mating tooth surface 3113 of the first mating tooth 3112a, the first mating tooth 3112a being the mating tooth 3112 furthest from the second end face 3114; when the rotation shaft 20 rotates in the first direction, the first limiting surface 3127 and the second limiting surface 3115 mutually limit each other to prevent the adjusting member 312 from rotating relative to the base 311.

[0128] Specifically, when it is necessary to adjust the distance between the first massage component 101 and the second massage component 102, the drive member 50 can drive the rotating shaft 20 to rotate in the second direction, and the adjusting part 3121 can slide along the mating part 3111 to move away from the mating part 3111, so that the adjusting part 312 gradually moves away from the base 311.

[0129] When no adjustment is needed, the drive member 50 can drive the rotating shaft 20 to rotate in the first direction. At this time, the adjustment member 312 does not rotate with the rotating shaft 20. Under the push of the force of the first elastic member 42 acting on the first massage component 101, the adjustment part 3121 can slide along the mating part 3111 and move close to the base 311 until the adjustment member 312 moves back to the initial position.

[0130] At this time, the first limiting surface 3127 of the adjusting part 3121 and the second limiting surface 3115 of the mating part 3111 mutually limit each other, and the adjusting member 312 no longer adjusts the distance when the rotating shaft 20 continues to rotate in the first direction. When the rotating shaft 20 rotates in the second direction again, the adjusting member 312 can move away from the base 311 again to adjust the distance between the first massage assembly 101 and the second massage assembly 102.

[0131] When the adjusting member 312 is in its initial position, the first limiting surface 3127 and the second limiting surface 3115 are engaged. When the rotating shaft 20 rotates in the second direction, the adjusting member 312 rotates with the rotating shaft 20, and the first adjusting tooth 3122a slides from the second mating tooth 3112b to the first mating tooth 3112a in sequence, and the distance between the adjusting member 312 and the base 311 gradually increases. If the user's target adjustment position is reached at a certain adjustment position, the user can operate the button to stop the adjustment. At this time, the driving member 50 can drive the rotating shaft 20 to rotate in the first direction, and the first adjusting tooth 3122a can be limited by the mating tooth 3122 that meshes with the current adjustment position. Under the elastic force of the first elastic member 42, the adjusting member 312 is stably maintained with the base 311 at the current adjustment position, so that the first massage component 101 and the second massage component 102 continue to maintain the current distance, and the first massage component 101 and the second massage component 102 perform massage operations in the first swing direction.

[0132] If further adjustment is needed, the rotating shaft 20 can continue to rotate in the second direction. Since the mating tooth surface 3113 of the first mating tooth 3112a is connected to the second limiting surface 3115, when the rotating shaft 20 continues to rotate in the second direction, the first adjusting tooth 3122a moves to the point where it abuts against the connection between the first mating tooth 3112a and the second limiting surface 3115, at which point the distance between the adjusting member 312 and the base 311 is at its farthest, and the adjusting member 312 reaches its limit position for adjustment. If the rotating shaft 20 continues to rotate in the second direction, the first adjusting tooth 3122a will fall off the first mating tooth 3112a, and the adjusting member 312 will move closer to the base 311 to its initial position, returning to the setting where the distance between the first massage component 101 and the second massage component 102 is at its farthest. Then, the distance between the first massage component 101 and the second massage component 102 can be readjusted according to the user's needs.

[0133] After each adjustment element 312 is adjusted to the position closest to the first massage component 101 and the second massage component 102, it can fall back from the base 311 to the initial position, that is, the position where the adjustment element is close to the base 311. Then, the next gear adjustment can be started by rotating the rotating shaft 20, making the adjustment process more continuous and improving the user experience.

[0134] Furthermore, when the user adjusts to the desired spacing, the rotating shaft 20 can stop rotating in the second direction and instead rotate in the first direction. At this time, the adjusting member 312 does not rotate with the rotating shaft 20, and the mating teeth 3112 and the adjusting teeth 3122 engage to keep the spacing between the first massage component 101 and the second massage component 102 at the current setting.

[0135] Please see Figure 10 , Figure 10 This is a schematic diagram illustrating the structure of the adjusting member and the base in accordance with an embodiment of this application. In some embodiments, the base 311 includes two mating portions 3111, and the two mating portions 3111 are symmetrically arranged with respect to the axis of the rotation shaft 20. The adjusting member 312 includes two adjusting portions 3121, and the two adjusting portions 3121 are symmetrically arranged with respect to the axis of the rotation shaft 20.

[0136] The two mating parts 3111 and the two adjusting parts 3121 are symmetrically arranged with respect to the axis of the rotating shaft 20, which can balance the force between the adjusting part 312 and the base 311, and make the external force on the two mating parts 3111 and the two adjusting parts 3121 evenly distributed. This prevents the adjusting part 312 from tilting to one side due to uneven force, which would affect the adjusting effect or even cause the adjusting part 312 to jam.

[0137] At the same time, an axial height difference is formed between the connection positions of the two adjusting parts 3121 and the connection positions of the two mating parts 3111. This allows each adjusting part 312 to fall back to its initial position from the base 311 after being adjusted to the position closest to the first massage component 101 and the second massage component 102. That is, the position where the adjusting part is close to the base 311. Then, the next gear adjustment can be started by rotating the rotating shaft 20, making the adjustment process more continuous and improving the user experience.

[0138] Furthermore, the arrangement of two adjusting parts 3121 and two mating parts 3111 can shorten the adjusting process. The rotating shaft 20 only needs to rotate 180° in the second direction to complete the adjusting process, thereby improving the adjusting efficiency of the adjusting mechanism 30.

[0139] Please see Figures 6 to 9 In some embodiments, the adjusting member 312 includes a support portion 3129, two adjusting portions 3121 are disposed on the outer periphery of the support portion 3129, at least a portion of the support portion 3129 is exposed outward along the axial direction of the rotation shaft 20 to the adjusting portion 3121, and the mating portion 3111 can be sleeved on the support portion 3129.

[0140] The mating part 3111 of the base 311 can surround the support part 3129 of the adjusting member 312, so that the mating part 3111 can also limit the adjusting member 312 in the radial direction of the rotating shaft 20 and the base 311, so as to avoid excessive radial offset of the adjusting member 312 and wear between the adjusting member 312 and the rotating shaft 20.

[0141] Meanwhile, the fitting part 3111 is sleeved on the support part 3129 so that the support part 3129 can support the fitting part 3111 and prevent the fitting part 3111 from shaking under the influence of external forces.

[0142] Please see Figure 11 , Figure 11 This is the fourth schematic diagram of the structure of the massage mechanism 100 provided in the embodiments of this application. In some embodiments, the massage mechanism 100 further includes a gear set 801, which is connected to the output shaft of the drive member 50, and the output shaft of the drive member 50 is perpendicular to the axial direction of the rotating shaft 20; and a bevel gear assembly 802, which is sleeved on the rotating shaft 20 and is connected to the gear set 801.

[0143] The drive component 50 is connected to the gear set 801 via an output shaft. The rotation of the output shaft of the drive component 50 drives the gear set 801 to rotate, which in turn drives the bevel gear assembly 802 to rotate. The output shaft of the drive component 50 is perpendicular to the axis of the rotating shaft 20. The bevel gear assembly 802 can change the rotation direction of the output shaft of the drive component 50, thereby driving the rotating shaft 20 to rotate, thus realizing the drive component 50 to drive the rotating shaft 20.

[0144] Optionally, the gear set 801 may include a first transmission gear and a second transmission gear.
