Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a massage mechanism with adjustable massage intensity and its application in massage devices. Background Technology

[0002] In today's fast-paced lifestyle, massage devices are widely popular due to their ability to effectively relieve muscle fatigue and promote blood circulation. As the core component of a massage device, the massage mechanism directly impacts the massage effect and user experience. Traditional massage mechanisms typically consist of a housing, massage components, and a drive assembly, with the massage components using rotational power provided by the drive assembly to perform the massage movements. To meet the personalized needs of different users for massage intensity, massage mechanisms with adjustable intensity have emerged.

[0003] In existing technologies, there are various ways to adjust massage intensity, one common method being through a threaded connection. Specifically, this design typically includes a threaded adjusting rod and a mating threaded sleeve. By rotating the adjusting rod, its relative position to the threaded sleeve is changed, thereby adjusting the height of the massage head and thus the massage intensity. However, using a threaded connection to adjust massage intensity is prone to wear during long-term use, leading to malfunction of the adjustment function or a decrease in adjustment accuracy. This not only affects the lifespan of the massage mechanism but also increases the user's maintenance costs. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a new adjustable massage mechanism design. This design utilizes a pressure drive mechanism, employing the cooperation of a pressure groove and a pressure member to achieve adjustment of the massage intensity.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable massage mechanism includes a housing, a massage component, and a drive component capable of outputting rotational power. The massage component includes a massage head and an output shaft. The massage head is fixed to the output shaft to obtain the rotational power to perform a massage action. The drive component includes a rotating sleeve, which is attached to the output shaft via at least two pressing drive mechanisms. Each pressing drive mechanism includes a pressing groove and a pressing member that cooperates with the pressing groove.

[0007] The pressure groove is configured to slope from top to bottom, and when the massage head contacts the massage area, the force applied by the pressure groove to the pressure member or the pressure member to the pressure groove can drive the output shaft to move relative to the rotating sleeve along the axial direction, so as to change the massage intensity by changing the height of the massage head.

[0008] Furthermore, the rotating sleeve is configured to rotate only around a set axis, and the output shaft cooperates with the rotating sleeve to enable the output shaft to rotate around or move along the set axis via a pressing drive mechanism.

[0009] Furthermore, the pressing member includes a pressing part for pressing against the pressing groove and a sliding part for sliding along the pressing groove, the sliding part being integrally formed with the pressing part.

[0010] Furthermore, the pressure groove includes a driving part and a limiting part. When the output shaft moves along a set axis, the limiting part is configured to provide a force to counteract the horizontal component force generated by the driving part on the pressure member.

[0011] Furthermore, the pressing groove is disposed on the rotating sleeve, and the pressing member is disposed on the output shaft. The force applied by the pressing groove to the pressing member can drive the pressing member to move along the axial direction of the rotating sleeve.

[0012] Furthermore, the pressing member is configured as a protrusion that projects radially outward from the output shaft.

[0013] Furthermore, the pressing groove is disposed on the output shaft, the pressing member is disposed on the rotating sleeve, and the force applied by the pressing member to the pressing groove can drive the pressing groove to move along the axial direction of the rotating sleeve.

[0014] Furthermore, the protrusion is configured to project radially inward from the rotating sleeve.

[0015] Furthermore, when the driving component drives the rotating sleeve to move relative to the output shaft in the first direction, the massage head can be adjusted to reach the first massage depth; when the driving component drives the rotating sleeve to move relative to the output shaft in the second direction, the massage head can be adjusted to reach the second massage depth.

[0016] A massage device includes the aforementioned massage mechanism with adjustable massage intensity.

[0017] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0018] 1. This utility model adjusts the massage intensity through a pressure-driven mechanism. This mechanism includes a pressure groove and a pressure member, the pressure groove being arranged inclined from top to bottom. When the massage head contacts the massage area, the force between the pressure groove and the pressure member drives the output shaft to move relative to the rotating sleeve along its axial direction, thereby changing the height of the massage head. This adjustment method eliminates the need for rotation; it is achieved solely through the contact force between the massage head and the massage area, greatly improving the convenience of adjustment.

[0019] 2. The pressure-driving mechanism in this invention employs a sliding fit, which significantly reduces wear compared to a threaded fit. The contact surface between the pressure groove and the pressure component is a sliding surface, and wear can be further reduced through lubrication. Therefore, the massage mechanism of this invention has a longer service life and reduces user maintenance costs.

[0020] 3. The drive assembly of this invention can drive the rotating sleeve and the output shaft to move relative to each other along a first direction or a second direction, thereby adjusting the massage head to reach a first massage depth or a second massage depth. This bidirectional adjustment method meets the user's needs for different massage depths and improves the applicability and flexibility of the massage device. Attached Figure Description

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0035] Example 1:

[0036] refer to Figures 1 to 3 This utility model provides a massage mechanism with adjustable massage intensity, including a housing 100, a massage component 200, and a drive component 300 capable of outputting rotational power. The massage component 200 includes a massage head 210 and an output shaft 220, with the massage head 210 attached to the output shaft 220 to obtain rotational power to perform massage actions.

[0037] The drive assembly 300 includes a rotating sleeve 310, which is attached to the output shaft 220 via at least two pressing drive mechanisms 400. Each pressing drive mechanism 400 includes a pressing groove 410 and a pressing member 420 that mates with the pressing groove 410. The pressing groove 410 is configured to slope from top to bottom, and when the massage head 210 contacts the massage area, the force exerted by the pressing groove 410 on the pressing member 420 or by the pressing member 420 on the pressing groove 410 can drive the output shaft 220 to move relative to the rotating sleeve 310 along its axial direction, thereby changing the massage intensity by altering the height of the massage head 210.

[0038] Specifically, the rotating sleeve 310 is configured to rotate only around a set axis. The output shaft 220 cooperates with the rotating sleeve 310, enabling the output shaft 220 to rotate around or move along the set axis via the pressing drive mechanism 400. Thus, when the rotating sleeve 310 rotates, its rotational power is transmitted to the output shaft 220 through the pressing drive mechanism 400, causing the output shaft 220 to drive the massage head 210 to rotate, thereby performing a massage action.

[0039] refer to Figures 4 to 6 The pressing member 420 includes a pressing portion 421 for pressing against the pressing groove 410 and a sliding portion 422 for sliding along the pressing groove 410. The sliding portion 422 is integrally formed with the pressing portion 421 on the side of a protruding cylinder. This structure allows the pressing member 420 to slide stably within the pressing groove 410 and transmits the rotational power of the rotating sleeve 310 to the output shaft 220.

[0040] The pressure groove 410 includes a drive portion 411 and a limiting portion 412. When the output shaft 220 moves along a set axis, the limiting portion 412 is configured to provide a force to counteract the horizontal component force generated by the drive portion 411 on the pressure member 420. Specifically, during the upward movement, the bottom portion of the pressure groove 410 is configured as the drive portion 411 that drives the pressure member 420 upward, while the top portion of the pressure groove 410 is configured as the limiting portion 412 that provides a force to counteract the horizontal component force generated by the drive portion 411 on the pressure member 420. The opposite is true during the downward movement. This structure allows the output shaft 220 to remain stable when moving along the set axis, avoiding unnecessary swaying.

[0041] In this embodiment, the pressing groove 410 is disposed on the rotating sleeve 310, and the pressing member 420 is disposed on the output shaft 220. The force applied by the pressing groove 410 to the pressing member 420 can drive the pressing member 420 to move along the axial direction of the rotating sleeve 310. Specifically, the pressing member 420 is configured as a protrusion that protrudes radially outward from the output shaft 220. This structure allows the pressing member 420 to slide stably within the pressing groove 410 and transmits the rotational power and axial movement force of the rotating sleeve 310 to the output shaft 220.

[0042] The drive assembly 300 also includes a drive gear 320 and a motor 330. The drive gear 320 is integrally formed with the rotating sleeve 310 to drive the rotating sleeve 310 to rotate. The motor 330 drives the rotating sleeve 310 to rotate through the drive gear 320, thereby driving the output shaft 220 and the massage head 210 to rotate, thus performing a massage action.

[0043] To improve output stability, there are two pressure grooves 410 and two pressure members 420. The two pressure grooves 410 are spaced apart on the side wall of the rotating sleeve 310, and the pressure members 420 are spaced apart on the output shaft 220, with the pressure members 420 corresponding to the pressure grooves 410. This structure allows the rotational power and axial movement force of the rotating sleeve 310 to be transmitted to the output shaft 220 more stably, improving the stability and reliability of the massage mechanism.

[0044] The working principle of the massage mechanism in this embodiment is as follows:

[0045] When the massage head 210 contacts the massage area, the massage area applies a reaction force to the massage head 210. This reaction force is transmitted to the pressure member 420 via the output shaft 220, causing the pressure member 420 to slide within the pressure groove 410. Since the pressure groove 410 is inclined from top to bottom, the pressure member 420 experiences an axial force from the pressure groove 410 during sliding, causing the output shaft 220 to move relative to the rotating sleeve 310 along its axial direction. This changes the height of the massage head 210, thereby altering the massage intensity.

[0046] When the massage head 210 experiences a large massage reaction force, the output shaft 220 will move downward relative to the rotating sleeve 310, lowering the height of the massage head 210 and reducing the massage intensity. When the massage head 210 experiences a small massage reaction force, the output shaft 220 will move upward relative to the rotating sleeve 310, raising the height of the massage head 210 and increasing the massage intensity.

[0047] When the drive assembly (i.e., motor 330) drives the rotating sleeve 310 to move relative to the output shaft 220 in a first direction, the massage head 210 can be adjusted to reach a first massage depth; when the drive assembly drives the rotating sleeve 310 to move relative to the output shaft 220 in a second direction, the massage head 210 can be adjusted to reach a second massage depth. Thus, by controlling the rotation direction and speed of the drive assembly, the massage depth of the massage head 210 can be easily adjusted to meet the massage needs of different users.

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 lies in the different configuration positions of the pressing groove and the pressing member. Specifically, the pressing groove is configured on the output shaft, and the pressing member is configured on the rotating sleeve. The force applied by the pressing member to the pressing groove can drive the pressing groove to move along the axial direction of the rotating sleeve. Correspondingly, the pressing member is configured as a protrusion that protrudes radially inward from the rotating sleeve.

[0050] This structure also allows for adjustment of massage intensity. When the massage head contacts the massage area, the massage area applies a reaction force to the massage head. This reaction force is transmitted to the pressure groove via the output shaft, causing the pressure groove to slide on the pressure member. Because the pressure groove is inclined from top to bottom, it experiences an axial force from the pressure member during sliding, causing the output shaft to move relative to the axis of the rotating sleeve. This changes the height of the massage head, thus altering the massage intensity.

[0051] The other structures are the same as in Example 1, and will not be described again here.

[0052] Example 3:

[0053] This embodiment provides a massage device, including a massage mechanism with adjustable massage intensity as described in Embodiment 1 or Embodiment 2. This massage device can be any massage equipment requiring a massage mechanism, such as a massage chair, massage pillow, or massage stick.

[0054] Because this massage device uses the massage mechanism of this invention, it has the advantage of adjustable massage intensity, which can meet the massage needs of different users and improve the massage effect and user experience.

[0055] Extended Implementation

[0056] Based on the above embodiments, the present invention can be extended in the following ways:

[0057] The number and arrangement of the pressure grooves and pressure components can be adjusted according to actual needs. For example, three or more pressure grooves and pressure components can be set to improve the stability and reliability of the massage mechanism.

[0058] The tilt angle and shape of the pressure groove can be adjusted according to actual needs. For example, the pressure groove can be designed in the shape of an arc or wave to achieve different massage intensity adjustments.

[0059] The pressure groove can also be tilted gradually from bottom to top. In order to increase the upward speed of the massage head, the tilt angle of the pressure groove is smaller than the vertical angle, which will not be elaborated on here.

[0060] The massage mechanism of this invention can also be combined with other massage techniques, such as air pressure massage and kneading massage, to achieve a more comprehensive massage effect.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
