Description

Technical Field

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

[0002] In the technological development of massage equipment, the massage mechanism, as a core component, directly affects the comfort, precision, and user experience of the massage. A traditional massage mechanism typically includes a robust housing, a drive unit, and at least one massage unit. The massage unit generally consists of a massage head, a threaded post fixed to the massage head, and a mating threaded sleeve. Through the rotational movement of the drive unit, the threaded sleeve moves up and down along the threaded post, thereby driving the massage head to massage the user.

[0003] However, existing massage mechanisms often adjust massage intensity by changing the output power of the drive unit or adjusting the contact pressure between the massage head and the body. While these methods can adjust massage intensity to some extent, they are complex to operate and have a limited adjustment range. Furthermore, due to the mating relationship between the threaded post and the threaded sleeve, relative rotation can easily occur between them when the massage head moves up and down. This not only reduces transmission efficiency and increases energy consumption but also accelerates thread wear, shortening the lifespan of the massage mechanism. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a massage mechanism with adjustable massage intensity.

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

[0006] A massage mechanism with adjustable massage intensity includes a housing, a drive unit, and at least two massage units arranged at intervals. Each massage unit includes a massage head and a threaded post fixed to the massage head. The drive unit includes a threaded sleeve that is pulsatorically connected to the threaded post to drive the massage head to move up and down.

[0007] A synchronous link is connected between the two massage units, and the two ends of the synchronous link are respectively associated with the two massage units so that the two massage heads move up and down synchronously.

[0008] The synchronous connecting rod has a damping mechanism that makes damping contact with the massage unit. The damping mechanism applies a damping force to the massage unit to impede the rotation of the threaded column. This damping force is configured to limit the synchronous rotation of the threaded column and the threaded sleeve during the driven up and down movement of the massage head.

[0009] Furthermore, the damping mechanism includes:

[0010] The braking part, which contacts the two massage heads connected to the synchronous linkage to apply damping force, and

[0011] An elastic support portion is configured between the braking parts.

[0012] Furthermore, the end of the braking part that contacts the massage head is provided with several protruding ridges.

[0013] Furthermore, the elastic support is configured such that the damping force is less than the driving force of the drive device, thereby reducing wear between the massage head and the damping mechanism through elastic deformation.

[0014] Furthermore, the elastic support includes a spring member.

[0015] Furthermore, the synchronizing link includes mounting sleeves disposed at both ends and sleeved on the outside of the massage head, and an assembly rod disposed in the middle portion to be suitable for mounting the damping mechanism.

[0016] Furthermore, the mounting sleeve has an opening at the braking part.

[0017] Furthermore, the threaded sleeve is configured to rotate only about a set axis, and the threaded post engages with the threaded sleeve to allow the threaded post to rotate about or move along the set axis.

[0018] Furthermore, the mating portion of the threaded post and the threaded sleeve occupies 1 / 3 to 2 / 3 of their thread length to increase the mating strength of the threads of the threaded post and the threaded sleeve.

[0019] Furthermore, the threaded post has a limiting portion for restricting the relative movement of the threaded sleeve and the threaded post. When the threaded sleeve abuts against the limiting portion, the damping force is configured to be less than the driving force of the driving device, so that the massage head rotates with the threaded post to perform a massage action on the massage area.

[0020] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0021] 1. This utility model connects two massage units into one unit to achieve synchronous up-and-down movement of the two massage heads. Simultaneously, a damping mechanism is configured on the synchronous connecting rod to apply resistance and brake the massage heads, allowing the threaded column and threaded sleeve to move relative to each other along the axial direction of the threaded column. This changes the massage intensity by altering the height of the massage heads, allowing users to easily adjust the massage intensity according to their personal preferences and needs for a more personalized massage experience.

[0022] 2. The elastic support (such as a spring) in the damping mechanism of this utility model reduces wear between the massage head and the damping mechanism through elastic deformation, thus extending the service life of the massage core. At the same time, the elastic support also acts as a buffer, making the massage process gentler and more comfortable.

[0023] 3. In this invention, when the threaded sleeve abuts against the upper limit part and the massage head rotates with the threaded column to perform a massage action on the massage area, without the support and connection of the synchronous connecting rod, a single massage unit may experience a shift in its rotation axis due to uneven force. However, the connecting rod in this patent connects two massage units, forming a stable structural frame that effectively prevents this shift. Even during high-intensity massage, the rotation axis of the massage unit remains stable, thereby increasing the strength and durability of the massage unit at its highest setting.

[0044] 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.

[0045] Please see Figures 1-3 This utility model discloses a massage mechanism with adjustable massage intensity, which is mainly used in massage units such as massage pillows, cushions, or massage chairs. In this embodiment, the massage mechanism includes a housing 100, a drive device 300, and two massage units 200. Each massage unit 200 includes a massage head 210 and a threaded post 220 fixed to the massage head. The drive device 300 includes a threaded sleeve that is pulsatorically connected to the threaded post 220 to drive the massage head 210 to move up and down. The housing 100 has a mounting cavity 110, in which the threaded sleeve is disposed. The drive device 300 also includes a motor 310, and a transmission gear set 600 is disposed between the motor 310 and the threaded sleeve. In this embodiment, the threaded sleeve is a drive gear 320. The drive gear 320 is configured to rotate only around a set axis. The threaded post 220 is threadedly engaged with the drive gear 320 to cause the massage unit 300 to rotate around or move along the set axis. Two massage units 200 are connected as one unit by a synchronizing link 400 so that the two massage heads 210 can move up and down synchronously. Furthermore, the synchronizing link 400 has a damping mechanism 500 that makes damping contact with the massage unit 200. The damping mechanism 500 applies a damping force to the massage unit 200 to resist the rotation of the threaded post 220. The damping force is configured to limit the synchronous rotation of the threaded post 220 and the threaded sleeve during the driven up and down movement of the massage head 210.

[0046] It should be noted that the damping mechanism 500 of this invention is configured on the connecting member, and applies a damping force to brake the massage head 210, preventing the massage head 210 from moving under certain conditions. That is, when the damping force is applied, the threaded post 220 and the threaded sleeve can move relative to each other along the axial direction of the threaded post 220, thereby changing the height of the massage head 210 and thus changing the massage intensity. Through the relative movement of the threaded post 220 and the threaded sleeve, and by precisely controlling the relationship between the damping force and the driving force, the rotational massage function of the massage head 210 under specific conditions is achieved. This design not only improves the flexibility and versatility of the massage but also allows the massage mechanism to adapt to more diverse massage needs. Users can easily adjust the massage intensity according to their individual needs to obtain a more personalized massage experience. Furthermore, since the massage mechanism generally has multiple massage units 200, when the threaded sleeve abuts against the upper limit part and the massage head 210 rotates with the threaded post 220 to perform massage actions on the massage area, without the support and connection of the synchronous connecting rod 400, a single massage unit may experience a shift in its rotation axis due to uneven force. The synchronous linkage in this patent connects the two massage units, forming a stable structural frame that effectively prevents such misalignment. Even during high-intensity massage, the rotation axis of the massage component remains stable, thereby increasing the strength and durability of the massage component at high settings.

[0047] Please see Figures 4-5 The synchronizing linkage 400 includes mounting sleeves 410 disposed at both ends and sleeved outside the massage head 210, and an assembly rod 420 disposed in the middle for mounting the damping mechanism 500. See also... Figure 1 The damping mechanism 500 includes: braking portions 510 disposed at both ends inside the synchronizing link 400 and in contact with two massage heads 210 connected to the synchronizing link 400 to apply damping force; and an elastic support portion 520 disposed between the two braking portions 510. The elastic support portion 520 is configured to reduce wear between the massage heads and the damping mechanism through elastic deformation when the damping force is configured to be less than the driving force of the driving device. The mounting sleeve 410 has an opening 430 at the braking portion 510 of the damping mechanism 500, which is configured to allow the braking portion 500 to contact the massage head 210 to apply damping force. Further, the end of the braking portion 510 that contacts the massage head 210 is provided with a plurality of protrusions 511, which specifically contact the massage head 210 to apply damping force. The elastic support portion 520 is a spring member 522. To improve the stability of the damping mechanism 500 and prevent separation between the elastic support 520 and the braking part 521, a cover plate 440 is also provided at the top of the synchronous link 400.

[0048] Please see Figures 6-8The threaded post 220 has an upper limit portion 221 for limiting the relative movement of the threaded sleeve and the threaded post 220, and a lower limit portion 222 for limiting the relative movement of the threaded sleeve and the threaded post. Specifically, the drive device 300 is connected to the drive gear 320 to drive the drive gear 320 to rotate. When the massage head 210 contacts the massage area, the threaded post 220 and the drive gear 320 can move relative to each other along the axial direction of the threaded post 220, so as to change the massage intensity by changing the height of the massage head 210. When the drive gear 320 abuts against the upper limit portion 221 or the lower limit portion 222, the massage head 210 rotates with the threaded post 220 to perform a massage action on the massage area.

[0049] The threaded post 220 includes a rod body with an external thread on its outer circumferential surface. This external thread can be a triangular thread or a trapezoidal thread, etc. The threaded post 220 is connected to the drive device 200 and can rotate under the drive of the drive device 200. Specifically, the drive gear 320 is a cylindrical sleeve with an internal thread on its inner wall, which is adapted to the external thread of the threaded post 220. Correspondingly, this internal thread can be a triangular thread or a trapezoidal thread, etc. The drive gear 320 is nested on the outside of the threaded post 220, with the internal and external threads meshing. It can be understood that when the threaded post 220 rotates relative to the drive gear 320, the threaded post 220 moves with its axial direction as the set axis. The massage head 210 is fixedly connected to the threaded post 220 to move together with it. Furthermore, to further increase the strength of the threaded engagement between the threaded post 220 and the threaded sleeve, the mating portion of the threaded post 220 and the threaded sleeve occupies 1 / 3 to 2 / 3 of its thread length.

[0050] 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.
