Description

Technical Field

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

[0002] Massage chairs utilize mechanical rolling and squeezing forces to achieve massage, which helps relax user muscles and eliminate fatigue. The massage mechanism is the core component that performs the massage actions.

[0003] In some related technologies, the massage mechanism includes multiple air bags arranged in a circumferential direction. The kneading massage is achieved by the alternating inflation and deflation of multiple air bags. This method requires a large number of air bags and a complex control program to precisely control the timing of inflation and deflation of each air bag, resulting in high costs. Furthermore, the inflation and deflation process of the air bags takes time, resulting in slow kneading massage speed and weak intensity. Utility Model Content

[0004] The embodiments of this application aim to provide a massage mechanism transmission mechanism, a massage mechanism, and a massage device, so as to at least improve the problems of high cost, slow massage speed, and weak massage intensity of massage mechanisms.

[0005] In order to solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a massage mechanism transmission mechanism, which includes a housing, a first rotating member, a driving device, and a telescopic air bag. The first rotating member is rotatably disposed on the housing about a first axis, and the first rotating member can also move relative to the housing in a direction parallel to the first axis. The driving device is disposed on the housing and is drively connected to the first rotating member, and the driving device is used to drive the first rotating member to rotate relative to the housing about the first axis. The telescopic air bag is disposed on the housing and has a clearance structure. The first rotating member passes through the clearance structure and the telescopic air bag and is drively connected to the driving device. The telescopic air bag is used to drive the first rotating member to move in a direction parallel to the first axis.

[0007] In some embodiments, the massage mechanism further includes a second rotating member, which is rotatably disposed on the housing about the first axis; the driving device is used to drive the second rotating member to rotate relative to the housing about the first axis, the second rotating member is used to transmit torque about the first axis to the first rotating member, and the first rotating member is used to move relative to the second rotating member in a direction parallel to the first axis; the first rotating member and / or the second rotating member passes through the air-sheltered structure; the telescopic air bag is used to drive the first rotating member to move relative to the second rotating member in a direction parallel to the first axis.

[0008] In some embodiments, the housing includes a guide rod parallel to the first axis; the massage mechanism includes a sliding member slidably disposed on the guide rod, and the first rotating member rotatably disposed on the sliding member about the first axis; one end of the telescopic air bag is functionally connected to the housing, and the other end of the telescopic air bag is functionally connected to the sliding member.

[0009] In some embodiments, the sliding member includes a first sliding member and a second sliding member, the first sliding member being slidably disposed on the guide rod; the first rotating member includes a limiting disk, the limiting disk being rotatably clamped between the first sliding member and the second sliding member about the first axis.

[0010] In some embodiments, the massage mechanism further includes an elastic reset member connected to the first rotating member, which elastically causes the first rotating member to reset against the action of the telescopic air bag.

[0011] In some embodiments, the massage mechanism further includes a pneumatic system fluidly connected to the telescopic air bag for supplying air to the telescopic air bag and / or drawing air from the telescopic air bag.

[0012] In some embodiments, the telescopic airbag includes a plurality of bags arranged in a direction parallel to the first axis.

[0013] In some embodiments, the massage mechanism further includes a transmission component, which includes a worm gear and a worm. The worm gear is rotatably disposed on the housing about the first axis, and the worm is rotatably disposed on the housing. The worm meshes with the worm gear. The drive device is drivenly connected to the worm, and the worm gear is drivenly connected to the first rotating member.

[0014] Secondly, embodiments of this application provide a massage mechanism, the massage mechanism including a massage component and a massage mechanism transmission mechanism as described in any of the above claims; the massage component is disposed on the first rotating member and rotates with the first rotating member around the first axis.

[0015] Thirdly, embodiments of this application provide a massage device, which includes the massage mechanism.

[0016] The massage mechanism, massage core, and massage device of this application embodiment allow the massage component to be mounted on the first rotating member. The massage component is driven to rotate by a drive device to achieve massage, eliminating the need for an air bag, thus reducing the cost of air bag inflation and deflation control and addressing the high cost of the massage core. The use of a telescopic air bag increases the massage stroke and improves the massage intensity, addressing the issue of weak massage intensity when using an air bag. The drive device drives the massage component to achieve rolling massage, increasing the rolling massage speed.

[0017] By having the telescopic airbag surround or partially surround the first rotating component, the telescopic airbag and the first rotating component become more compact, which helps to reduce the size of the massage mechanism.

[0018] The above description is merely an overview of the technical solution of this application.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0052] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0053] Please see Figures 1 to 3 This application provides a massage mechanism 100, which includes a massage mechanism transmission mechanism and a massage component 5. The massage mechanism transmission mechanism includes a housing 1, a rotating mechanism 2, a driving device 31, and a telescopic component 4.

[0054] The housing 1 described above serves to house and protect the rotating mechanism 2, the drive device 31, and the telescopic assembly 4. The housing 1 also houses at least a portion of the massage member 5, allowing the massage member 5 to be concealed within the housing 1 when not in operation, thus protecting the massage member 5. The housing 1 may be box-shaped.

[0055] For the rotating mechanism 2 mentioned above, please refer to Figure 2 and Figure 3 The rotating mechanism 2 includes a first rotating member 21, which is rotatably mounted on the housing 1 about a first axis L. The first rotating member 21 can also move relative to the housing 1 in a direction parallel to the first axis L. In this embodiment, the massage member 5 is mounted on the first rotating member 21 and rotates with it about the first axis L, thereby realizing the rotation and lifting of the massage member 5. The lifting of the massage member 5 means that the massage member 5 moves relative to the housing 1 in a direction parallel to the first axis L, allowing the massage member 5 to be housed inside the housing 1 or extend out of the housing 1. The first axis L is the rotation axis of the first rotating member 21.

[0056] In some embodiments, please refer to Figure 2 and Figure 3 The housing 1 includes a guide rod 11, which is parallel to the first axis L. The rotating mechanism 2 includes a sliding member 23, which is slidably disposed on the guide rod 11. A first rotating member 21 is rotatably disposed on the sliding member 23 about the first axis L. The first rotating member 21 is rotatably disposed on the sliding member 23, and the sliding member 23 can slide along the guide rod 11, thereby enabling the first rotating member 21 to rotate about the first axis L and move relative to the housing 1 in a direction parallel to the first axis L.

[0057] For the sliding member 23 mentioned above, please refer to Figure 2 and Figure 3The sliding member 23 includes a first sliding member 231 and a second sliding member 232. The first sliding member 231 is slidably disposed on the guide rod 11. The first rotating member 21 includes a limiting disk 211, which is rotatably clamped between the first sliding member 231 and the second sliding member 232 about a first axis L. Thus, the first rotating member 21 can move synchronously with the sliding member 23 relative to the housing 1, and the first rotating member 21 can rotate about the first axis L.

[0058] The first sliding member 231 is provided with a first guide hole 2311, and the guide rod 11 passes through the first guide hole 2311, thereby slidably mounting the first sliding member 231 on the guide rod 11. There can be multiple guide rods 11 and multiple first guide holes 2311, with each guide rod 11 passing through a first guide hole 2311, enhancing the stability of the first sliding member 231 slidingly connected to the housing 1.

[0059] Optionally, the second sliding member 232 is provided with a second guide hole (not shown), and the guide rod 11 passes through the first guide hole 2311 and the second guide hole in sequence, thereby slidably mounting the first sliding member 231 and the second sliding member 232 on the guide rod 11. There can be multiple guide rods 11, and multiple first guide holes 2311 and second guide holes. Each guide rod 11 passes through one first guide hole 2311 and one second guide hole in sequence, enhancing the stability of the sliding connection between the first sliding member 231 and the second sliding member 232 and the housing 1.

[0060] In some embodiments, please refer to Figure 3 The guide rod 11 is set close to the inner wall of the housing 1, that is, the guide rod 11 is a guide rib, and the first guide hole 2311 extends to the edge of the first sliding member 231 to form a guide notch. This helps to increase the bending strength of the guide rod 11, improve the problem that the first sliding member 231 cannot slide normally along the guide rod 11 due to the bending of the guide rod 11, and reduce the friction between the first sliding member 231 and the guide rod 11.

[0061] The first sliding member 231 and the second sliding member 232 can be disc-shaped, shortening the thickness of the sliding member 23 along the direction parallel to the first axis L. The limiting disc 211 can be disc-shaped, shortening the distance between the first sliding member 231 and the second sliding member 232, thereby shortening the thickness of the sliding member 23 along the direction parallel to the first axis L.

[0062] The limiting plate 211 is rotatably clamped between the first sliding member 231 and the second sliding member 232 about the first axis L. For example, please refer to... Figure 2 and Figure 3The first rotating component 21 includes a bushing 212, a limiting disc 211 fitted onto the bushing 212, a first sliding component 231 having a first limiting hole 2312, and a second sliding component 232 having a second limiting hole 2321. Both ends of the bushing 212 pass through the first limiting hole 2312 and the second limiting hole 2321, respectively. The bushing 212 is connected to the massage component 5 via a drive mechanism, thereby mounting the massage component 5 onto the first rotating component 21. Optionally, the inner diameters of the first limiting hole 2312 and the second limiting hole 2321 are equal to the outer diameter of the bushing 212, meaning the bushing 212 mates with the shaft holes of the first limiting hole 2312 and the second limiting hole 2321, enhancing the stability of the first rotating component 21's rotation relative to the sliding component 23.

[0063] It should be noted that the limiting plate 211 is fixedly connected to the bushing 212, or the limiting plate 211 is an integral structure on the bushing 212. Thus, when the sliding member 23 slides along the guide rod 11, the bushing 212 and the limiting plate 211 move synchronously relative to the housing 1 in a direction parallel to the first axis L, thereby driving the massage member 5 to move relative to the housing 1 in a direction parallel to the first axis L. Optionally, the limiting plate 211 and the bushing 212 are an integral structure, for example, integrally molded.

[0064] In some embodiments, a thrust bearing 24 is provided between the limiting disc 211 and the first sliding member 231 and the second sliding member 232 to reduce the frictional force of the first rotating member 21 rotating relative to the sliding member 23. In this embodiment, the inner diameter of the first limiting hole 2312 and the second limiting hole 2321 can be larger than the outer diameter of the bushing 212, and the first limiting hole 2312 and the second limiting hole 2321 are only used for the bushing 212 to pass through.

[0065] The first sliding member 231 and the second sliding member 232 can be provided with tension by bolts or screws to clamp the limiting plate 211 between the first sliding member 231 and the second sliding member 232. Alternatively, the first sliding member 231 and the second sliding member 232 can be fixed relative to each other, and the limiting plate 211 can be installed between the first sliding member 231 and the second sliding member 232.

[0066] In some embodiments, please refer to Figure 2 and Figure 3 The rotating mechanism 2 further includes a second rotating member 22, which is rotatably mounted on the housing 1 about a first axis L. The second rotating member 22 is used to transmit torque about the first axis L to the first rotating member 21. The first rotating member 21 is also used to move relative to the second rotating member 22 in a direction parallel to the first axis L. Thus, the first rotating member 21 can be driven to rotate by driving the second rotating member 22 to rotate. For example, please refer to [reference needed]. Figure 2 and Figure 3The second rotating member 22 is provided with a drive shaft 221, and the first rotating member 21 is provided with a bushing 212. The bushing 212 is fitted onto the drive shaft 221. The drive shaft 221 and the bushing 212 are used to transmit torque about the first axis L to each other. The bushing 212 is used to move relative to the drive shaft 221 in a direction parallel to the first axis L. For example, the cross-section of the drive shaft 221 is adapted to the cross-section of the space inside the bushing 212, and the cross-section is non-circular, such as an ellipse, a polygon, or a closed shape formed by curves and line segments. Thus, the drive shaft 221 can slide within the bushing 212 in a direction parallel to the first axis L, and the drive shaft 221 cannot rotate relative to the bushing 212 about the first axis L.

[0067] The positions of the drive shaft 221 and the bushing 212 can be interchanged; that is, the second rotating member 22 is provided with the bushing 212, and the first rotating member 21 is provided with the drive shaft 221. When the first rotating member 21 is provided with the drive shaft 221, the limiting plate 211 is sleeved on the drive shaft 221, and the two ends of the drive shaft 221 pass through the first limiting hole 2312 and the second limiting hole 2321 respectively. The drive shaft 221 is connected to the massage member 5 for transmission, so that the massage member 5 is placed on the first rotating member 21.

[0068] The aforementioned drive device 31 is located on the housing 1 and is connected to the first rotating member 21 via a transmission connection. The drive device 31 drives the first rotating member 21 to rotate relative to the housing 1 around the first axis L. This, in turn, drives the massage member 5 to rotate around the first axis L. The drive device 31 can be a motor, a geared motor, or the like.

[0069] In some embodiments, please refer to Figure 2 and Figure 3 The massage mechanism's transmission system also includes a transmission assembly 32, which comprises a worm gear 321 and a worm 322. The worm gear 321 is rotatably mounted on the housing 1 about a first axis L, and the worm 322 is rotatably mounted on the housing 1. The worm 322 meshes with the worm gear 321. The drive device 31 may be, but is not limited to, a motor, and is connected to the worm 322 in a transmission manner. The drive device 31 drives the worm 322 to rotate, thereby causing the worm gear 321 to rotate about the first axis L.

[0070] In some embodiments, where the drive unit 31 is drively connected to the first rotating member 21, the drive unit 31 is used to drive the second rotating member 22 to rotate relative to the housing 1 about a first axis L. For example, please refer to... Figure 2 and Figure 3 The worm gear 321 is connected to the second rotating component 22, which in turn drives the first rotating component 21 and the massage component 5 to rotate around the first axis L.

[0071] In some embodiments, the second rotating member 22 is omitted, and the first rotating member 21 is directly connected to the worm gear 321. Due to the meshing characteristics of the worm gear 321 and the worm 322, when the worm gear 321 moves along its own axis, that is, along a direction parallel to the first axis L, as long as the worm gear 321 and the worm 322 are still meshed, power can still be transmitted between them. The thickness of the worm gear 321 along the direction parallel to the first axis L is greater than the stroke of the first rotating member 21 relative to the housing 1.

[0072] The worm gear 322 drives the worm wheel 321 to rotate, which has the effect of a speed reducer. That is, it reduces the rotation speed of the massage component 5 and increases the torque of the massage component 5. This can improve the problem of poor massage effect caused by the excessive rotation speed of the massage component 5, and also improve the problem of the massage component 5 being unable to rotate because the resistance it receives is greater than the torque of the massage component 5.

[0073] Furthermore, the cooperation between the worm gear 321 and the worm 322 can shorten the thickness of the transmission assembly 32 along the direction parallel to the first axis L, thereby shortening the thickness of the massage mechanism 100 along the direction parallel to the first axis L.

[0074] Please refer to Figure 1 The number of housing 1, rotating mechanism 2, telescopic component 4, massage component 5, worm gear 321 and worm 322 can be multiple. One drive device 31 can drive multiple worm gears 322 to rotate, thereby driving multiple massage components 5 to rotate, so as to reduce the number of drive devices 31.

[0075] In some other embodiments, the drive device 31 may also be a disc motor. In this embodiment, the worm gear 321 and worm 322 described above can be omitted from the massage mechanism transmission mechanism, and the drive device 31 is directly connected to the second rotating member 22 for transmission.

[0076] The telescopic component 4 is located on the housing 1 and is connected to the first rotating member 21 via a transmission connection. The telescopic component 4 drives the first rotating member 21 to move relative to the second rotating member 22 in a direction parallel to the first axis L. By driving one end of the first rotating member 21 relative to the second rotating member 22 in a direction parallel to the first axis L, the telescopic component 4 moves the first rotating member 21 relative to the housing 1 in a direction parallel to the first axis L, thereby achieving the lifting and lowering of the massage component 5.

[0077] In some embodiments, please refer to Figure 2 and Figure 3 The telescopic assembly 4 includes a telescopic air bag 41, which is disposed on the housing 1. The telescopic air bag 41 is used to drive the first rotating member 21 to move in a direction parallel to the first axis L. For example, please refer to [reference needed]. Figure 2 and Figure 3One end of the telescopic air bag 41 is connected to the housing 1, and the other end of the telescopic air bag 41 is connected to the sliding member 23. When the telescopic air bag 41 is inflated, it expands to push the sliding member 23 to slide along the guide rod 11; when the telescopic air bag 41 is deflated, it contracts to pull the sliding member 23 to slide along the guide rod 11.

[0078] Furthermore, the telescopic air bag 41 does not need to rotate synchronously with the first rotating member 21, which helps to reduce the volume and mass of the rotating part in the massage mechanism 100, reduce the energy consumption of driving the massage component 5 to rotate, and improve the response speed of the massage component 5 to rotate. When the telescopic air bag 41 is a telescopic air bag 41, the telescopic air bag 41 does not need to rotate synchronously with the first rotating member 21, which facilitates the connection of the telescopic air bag 41 to the air tube.

[0079] In other embodiments, one end of the telescopic air bag 41 may be connected to the first rotating member 21, and the other end may be connected to the sliding member 23 or the second rotating member 22. The telescopic air bag 41 rotates synchronously with the first rotating member 21. In this embodiment, although the telescopic air bag 41 rotates synchronously with the first rotating member 21, it does not transmit torque between the first rotating member 21 and the second rotating member 22, or it is not a primary component for torque transmission.

[0080] The telescopic airbag 41 may include multiple bags arranged in a direction parallel to the first axis L, thereby increasing the telescopic length of the telescopic airbag 41 in the direction parallel to the first axis L.

[0081] In some embodiments, please refer to Figures 2 to 4 The telescopic air bag 41 has a clearance structure 411, through which the first rotating member 21 passes and is connected to the drive device 31. The clearance structure 411 can be perforated, such as a round hole, an elliptical hole, or a square hole, meaning the telescopic air bag 41 surrounds the first rotating member 21; the clearance structure 411 can also be notched, meaning the telescopic air bag 41 is U-shaped. By having the telescopic air bag 41 surround or partially surround the first rotating member 21, the telescopic air bag 41 and the first rotating member 21 are more compact, which helps to reduce the size of the massage mechanism 100.

[0082] The air-sheltered structure 41 of the telescopic airbag 4 primarily provides an air-sheltered space for the first rotating member 21 to be driven by the second rotating member 22 or the driving device 31. For example, the first rotating member 21 can extend through the air-sheltered structure 411 and be driven by the second rotating member 22 or the driving device 31; or, the first rotating member 21 can partially penetrate the air-sheltered structure 411 and be driven by the second rotating member 22 or the driving device 31, for example, the first rotating member 21 is driven by the driving device 31 within the air-sheltered structure 411. As another example, the second rotating member 22 is driven by the driving device 31, and the second rotating member 22 passes through the air-sheltered structure 41 and is driven by the first rotating member 21. In this case, the first rotating member 21 can partially, completely, or not extend into the air-sheltered structure 411.

[0083] In some embodiments, please refer to Figure 2 and Figure 3 The first rotating member 21 and / or the second rotating member 22 pass through the clearance structure 411. The telescopic air bag 41 surrounds or partially surrounds the first rotating member 21 and / or the second rotating member 22, making the telescopic air bag 41 more compact with the second rotating member 22 and the first rotating member 21, which helps to reduce the volume of the massage mechanism 100. Furthermore, the telescopic air bag 41 actually surrounds or partially surrounds the bushing 212 and / or the drive shaft 221, which helps to shorten the distance between the resultant force of the telescopic air bag 41 on the sliding member 23 and the drive shaft 221, improving the problem of the sliding member 23 tilting relative to the housing 1, reducing the bending moment between the bushing 212 and the drive shaft 221, and reducing the friction between the bushing 212 and the drive shaft 221.

[0084] In some embodiments, please refer to Figure 4 The telescopic airbag 41 is disc-shaped, and the clearance structure 411 is circular, with the central axis of the clearance structure 411 coinciding with the central axis of the telescopic airbag 41, meaning the telescopic airbag 41 is annular. The annular telescopic airbag 41 is perfectly suited to the space between the first rotating member 21 and the second rotating member 22, resulting in a more compact arrangement between the telescopic airbag 41, the second rotating member 22, and the first rotating member 21.

[0085] In some embodiments, please refer to Figure 4 The telescopic air bag 41 includes a connecting nozzle 412. Since the telescopic air bag 41 does not need to rotate synchronously with the first rotating member 21 and the second rotating member 22, the connecting nozzle 412 can be set at any location on the telescopic air bag 41, for example, at the outer edge of the telescopic air bag 41, so as to pass through the wall of the housing 1.

[0086] In some embodiments, please refer to Figure 2 and Figure 3The telescopic assembly 4 also includes an elastic reset member 43, which is functionally connected to the first rotating member 21 and elastically causes the first rotating member to return to its original position against the action of the telescopic air bag 41. Exemplarily, the telescopic assembly 4 also includes a fixing member 42, with the telescopic air bag 41 supported on the side of the first sliding member 231 opposite to the second sliding member 232. The fixing member 42 is fixed to the housing 1 and is located on the side of the second sliding member 232 opposite to the first sliding member 231. The elastic reset member 43 may be, but is not limited to, a spring or a sheet spring, and is supported between the fixing member 42 and the second sliding member 232. Thus, the elastic reset member 43 applies pressure to the telescopic air bag 41 through the sliding member 23 to cause the telescopic air bag 41 to return to its original position.

[0087] Furthermore, by applying a pushing force to bring the first sliding member 231 and the second sliding member 232 closer together through the telescopic air bag 41 and the elastic reset member 43 respectively, the first sliding member 231 and the second sliding member 232 clamp the limiting plate 211, thereby eliminating the need to fix the first sliding member 231 and the second sliding member 232 relative to each other or provide tension through screws or other components, which helps to reduce the cost of the sliding member 23 and facilitates the disassembly and assembly of the sliding member 23.

[0088] The fixing member 42 can have the same structure as the first sliding member 231 and the second sliding member 232. For example, please refer to... Figure 3 The fixing member 42 is provided with a third guide hole 421. The guide rod 11 passes through the third guide hole 421, and the guide rod 11 and the third guide hole 421 are interference-fitted, thereby fixing the fixing member 42 to the guide rod 11, i.e., to the housing 1. There can be multiple guide rods 11 and multiple third guide holes 421. Each guide rod 11 passes through a third guide hole 421, which enhances the stability of the fixing member 42 connected to the housing 1. The fixing member 42 can be disc-shaped to shorten the thickness of the telescopic assembly 4 in the direction parallel to the first axis L.

[0089] The elastic reset member 43 can be a straight spring. The elastic reset member 43 and the telescopic air bag 41 are respectively supported on the opposite sides of the first sliding member 231 and the second sliding member 232, so as to drive the first sliding member 231 and the second sliding member 232 to clamp the limiting plate 211.

[0090] When the massage mechanism 100 of this embodiment is in operation: the drive device 31 drives the worm gear 322 to rotate, the worm gear 322 drives the worm wheel 321 to rotate around the first axis L, the worm wheel 321 drives the first rotating member 21 to rotate or drives the first rotating member 21 to rotate through the second rotating member 22, thereby driving the massage member 5 to rotate around the first axis L; when the telescopic air bag 41 contracts or expands, it drives the sliding member 23 to slide along the guide rod 11, and the first rotating member 21 is rotatably disposed on the sliding member 23 around the first axis L. Therefore, the telescopic air bag 41 drives the first rotating member 21 and the massage member 5 to move relative to the housing 1 in a direction parallel to the first axis L through contraction and expansion. In the above manner, the rotation of the massage member 5 relative to the housing 1 around the first axis L and the movement in a direction parallel to the first axis L can be realized.

[0091] During operation, when the telescopic air bag 41 inflates, it pushes against the limiting plate 211 via the sliding member 23, causing the first rotating member 21 to extend and extend the massage member 5 mounted on the first rotating member 21 to the working position, bringing it close to the human body for compression massage. At this time, the elastic reset member 43 is compressed. The drive device 31 drives the second rotating member 22 via the worm gear 322 and worm wheel 321. The rotating second rotating member 22 engages with the first rotating member 21 in the circumferential direction to transmit torque to the first rotating member 21, thereby causing the first rotating member 21 to rotate, which in turn causes the massage member 5 mounted on the first rotating member 21 to rotate, thus achieving rolling massage.

[0092] When the telescopic air bag 41 deflates, the elastic reset member 43 pushes the limiting plate 211 through the sliding member 23 to cause the first rotating member 21 to retract, and the telescopic air bag 41 is squeezed and contracted by the sliding member 23. The massage member 5 retracts to the storage position along with the first rotating member 21.

[0093] In this embodiment of the invention, the telescopic air bag 41 can be deflated by the compression of the sliding member 23 and the telescopic air bag 41 by the elastic reset member 43. For other embodiments, please refer to... Figure 5 The massage mechanism also includes a pneumatic system 200, which supplies air to the telescopic air bag 41. The pneumatic system 200 includes an air source device 7, which acts as a pneumatic unit and can inflate the telescopic air bag 41 and also draw gas from the telescopic air bag 41 to accelerate the deflation of the telescopic air bag 41.

[0094] The telescopic air bag 41 can also be deflated by magnetic force. For example, the first sliding member 231 is equipped with a magnetic attractor, such as a magnet; the housing 1 is equipped with a magnetically attracted member, such as a magnet or a ferromagnetic metal. When the telescopic air bag 41 is inflated and connected to the atmosphere, the telescopic air bag 41 first deflates and contracts under its own elasticity, so that the distance between the magnetic attractor and the magnetically attracted member gradually shortens, and the magnetic attraction between the magnetic attractor and the magnetically attracted member gradually increases. When the magnetic attraction increases to a certain extent, the magnetic attraction drives the first sliding member 231 to squeeze the telescopic air bag 41, thereby realizing the deflation of the telescopic air bag 41.

[0095] In some embodiments, the massage mechanism transmission mechanism omits the overarching concepts of the rotating mechanism 2 and the telescopic component 4, and directly includes sub-components of the rotating mechanism 2 and the telescopic component 4. For example, the massage mechanism transmission mechanism includes a first rotating member 21, a second rotating member 22, a sliding member 23, a thrust bearing 24, a telescopic air bag 41, a fixing member 42, and an elastic reset member 43.

[0096] For the massage component 5 mentioned above, please refer to Figure 2 and Figure 3 The massage component 5 includes a base 51 and massage protrusions 52. The massage protrusions 52 are located on the side of the base 51 opposite to the rotating mechanism 2, and the base 51 is fixed to the first rotating component 21. Preferably, the base 51 is detachably mounted to the first rotating component 21 using bolts or the like. The base 51 can be disc-shaped, with its central axis coinciding with the first axis L, making the base 51 more stable when rotating. The massage protrusions 52 can be hemispherical, improving the problem of the massage protrusions 52 scratching or abrading the user and enhancing massage safety. There can be multiple massage protrusions 52, i.e., two or more, arranged at intervals around the first axis L, thereby achieving kneading massage when the massage component 5 rotates. The number of massage protrusions 52 can be two, three, four, or five. The multiple massage protrusions 52 can be arranged circumferentially around the first axis L, and at equal angular intervals.

[0097] In some embodiments, the massage protrusion 52 is a ball, which is rotatably disposed on the base 51. When the massage member 5 rotates, the ball rolls to perform kneading massage, which helps to reduce the frictional force of the massage member 5 during rotation.

[0098] In some embodiments, the pneumatic system 200 is fluidly connected to the telescopic air bag 41 for supplying air to the telescopic air bag 41 and / or drawing air from within the telescopic air bag 41. Exemplarily, the pneumatic system 200 includes an air source device 7 and a fluid distribution device 8. The fluid distribution device 8 controls the opening and closing of the venting air passage of the telescopic air bag 41, and controls the opening and closing of the inflation air passage between the telescopic air bag 41 and the air source device 7.

[0099] For the gas source device 7 mentioned above, please refer to Figure 5As shown, the gas source device 7 has an intake port 71 and an exhaust port 72. The intake port 71 is for gas to flow in, and the exhaust port 72 is for gas to flow out. When the gas source device 7 is working, it draws in gas through the intake port 71 and then discharges compressed gas through the exhaust port 72 to supply gas. The intake port 71 of the gas source device 7 can be fluidly connected to the external environment, such as directly connected to the atmosphere. The exhaust port 72 of the gas source device 7 can be fluidly connected to the telescopic air bag 41 through the fluid distribution device 8 to supply air to the telescopic air bag 41. The intake port 71 of the gas source device 7 can also be fluidly connected to the telescopic air bag 41 through the fluid distribution device 8 to deflate the telescopic air bag 41.

[0100] For the fluid distribution device 8 described above, please refer to Figure 5 The fluid distribution device 8 includes a valve assembly 81. The valve assembly 81 fluidly connects the exhaust port 72 to the telescopic air bag 41 and controls the opening and closing of the air passage between the exhaust port 72 and the telescopic air bag 41. The valve assembly 81 also fluidly connects the intake port 71 to the telescopic air bag 41 and controls the opening and closing of the air passage between the intake port 71 and the telescopic air bag 41. For example, the valve assembly 81 has an air inlet 811, an inflation port 812, and a deflation port 813. The air inlet 811 is fluidly connected to the exhaust port 72 via a pipe, the inflation port 812 is fluidly connected to the telescopic air bag 41 via a pipe, and the deflation port 813 is fluidly connected to the intake port 71 via a pipe. The valve assembly 81 controls the opening and closing of the air passage between the inflation port 812 and the air inlet 811 and the deflation port 813, thereby controlling the opening and closing of the air passage between the telescopic air bag 41 and the intake port 71 and the exhaust port 72. The valve assembly 81 can be selected, but is not limited to, air valves, such as solenoid valves or SMA (Shape Memory Alloy) valves.

[0101] In some embodiments, please refer to Figure 5 As shown, the pneumatic system 200 also includes an air tank 9, which is fluidly connected between the air source device 7 and the fluid distribution device 8. The air tank 9 can be a metal tank, a plastic tank, etc., and can contain high-pressure gas. The storage of high-pressure gas in the air tank 9 is beneficial for improving the inflation speed and inflation response speed of the telescopic air bag 41.

[0102] In some embodiments, the pneumatic system 200 further includes a low-pressure generator 6, and a fluid distribution device 8 for controlling the opening and closing of the venting air passage between the telescopic air bag 41 and the low-pressure generator 6, in order to enhance the venting effect on the telescopic air bag 41.

[0103] For the low-voltage generator mentioned above, please refer to Figure 6The low-pressure generator 6 includes a generator body 61 and a low-pressure port 62. The generator body 61 has a first opening 611 and a second opening 612. The low-pressure port 62 is fluidly connected between the first opening 611 and the second opening 612. When gas flows from the first opening 611 to the second opening 612, the low-pressure port 62 generates negative pressure, meaning the air pressure at the low-pressure port 62 is lower than atmospheric pressure. Negative pressure refers to a true air pressure lower than standard atmospheric pressure, i.e., lower than 101.325 kPa. Negative pressure is usually expressed as the true air pressure minus standard atmospheric pressure; for example, negative pressure can be -40 kPa, -20 kPa, -10 kPa, etc. By connecting the low-pressure port 62 to the telescopic air bag 41, the telescopic air bag 41 can be deflated. The low-pressure port 62 is in fluid communication with the telescopic air bag 41. Because the low-pressure port 62 generates negative pressure, it will increase the degassing speed of the telescopic air bag 41, increase the degree of degassing of the telescopic air bag 41, and make the telescopic air bag 41 degas more completely and complete the degassing in a shorter time.

[0104] For example, the generator body 61 can be tubular, with openings at both ends of a first opening 611 and a second opening 612, respectively. A low-pressure port 62 can penetrate the tube wall of the generator body 61. Thus, gas flowing from the first opening 611 to the second opening 612 will flow through the low-pressure port 62. The flow velocity of the gas from the first opening 611 to the second opening 612 is greater than the flow velocity of the gas inside the low-pressure port 62. Since the faster the fluid flow velocity, the lower its pressure, the gas pressure flowing from the first opening 611 to the second opening 612 is less than the gas pressure inside the low-pressure port 62, causing the gas pressure at the low-pressure port 62 to decrease and fall below atmospheric pressure, i.e., generating negative pressure.

[0105] In some embodiments, please refer to Figure 5 The valve assembly 81 connects the low-pressure port 62 to the telescopic air bag 41 in fluid communication, and controls the opening and closing of the air passage between the low-pressure port 62 and the telescopic air bag 41. For example, the vent port 813 is connected to the low-pressure port 62 in fluid communication via a pipe; the valve assembly 81 controls the opening and closing of the air passage between the inflation port 812, the air inlet 811, and the vent port 813, thereby controlling the opening and closing of the air passage between the telescopic air bag 41 and the low-pressure generator 6.

[0106] In some embodiments, please refer to Figure 6As shown, the generator body 61 is provided with a low-pressure generating chamber 613, which is connected between the first opening 611 and the second opening 612. The low-pressure generating chamber 613 includes a first contraction chamber 6131, the end of which faces away from the first opening 611 and is in fluid communication with the low-pressure port 62. The first contraction chamber 6131 is a chamber whose cross-sectional area gradually decreases along the direction of fluid flow, and can be shaped like a frustum of a cone. When gas flows from the first opening 611 to the second opening 612, and passes through the first contraction chamber 6131, the cross-sectional area of ​​the chamber through which gas can pass gradually decreases, and the gas velocity increases, causing the gas pressure to decrease when passing through the first contraction chamber 6131, thereby enhancing the negative pressure at the low-pressure port 62. It can be understood that the faster the gas velocity when passing through the first contraction chamber 6131, the greater the negative pressure formed at the low-pressure port 62.

[0107] In some embodiments, please refer to Figure 6 As shown, the low-pressure generating chamber 613 also includes a diffusion chamber 6132, which is in fluid communication with the end of the first contraction chamber 6131 opposite to the first opening 611. The cross-sectional area of ​​the diffusion chamber 6132 is larger than that of the first contraction chamber 6131. ​​For example, the diffusion chamber 6132 is cylindrical, and the end of the first contraction chamber 6131 opposite to the first opening 611 is in fluid communication with the diffusion chamber 6132. The inner diameter of the diffusion chamber 6132 is larger than the inner diameter of the port at the end of the first contraction chamber 6131 in fluid communication with the diffusion chamber 6132. When gas flows from the first contraction chamber 6131 to the diffusion chamber 6132, the cross-sectional area of ​​the chamber through which gas can pass suddenly increases, making it difficult for the gas to expand into the entire diffusion chamber 6132. Furthermore, the gas velocity is relatively high, and the gas is jetted into the second opening 612, carrying gas from the diffusion chamber 6132 into the second opening 612, thus reducing the gas pressure within the diffusion chamber 6132. Furthermore, in this embodiment of the invention, the low-pressure port 62 is in fluid communication with the first contraction chamber 6131 through the diffusion chamber 6132. Compared with the low-pressure port 62 being directly connected to the inner wall of the first contraction chamber 6131 away from the first opening 611, this can enhance the negative pressure at the low-pressure port 62.

[0108] In further embodiments, please refer to Figure 6As shown, the generator body 61 also includes a converging cylinder 614 and a nozzle 615. The converging cylinder 614 is conical in shape, with its larger opening end in fluid communication with a first opening 611, and its other end facing a second opening 612. The internal space of the converging cylinder 614 defines a first converging chamber 6131. ​​The nozzle 615 is cylindrical, with one end in fluid communication with the smaller opening end of the converging cylinder 614, and its other end facing the second opening 612. This allows the gas flowing out of the converging cylinder 614 to be guided and constrained by the nozzle 615, forming a jet stream. A diffuser chamber 6132 is defined between the outer wall of the converging cylinder 614 and the nozzle 615, and the inner wall of the generator body 61. This allows the rapid airflow ejected from the nozzle 615 to more easily induce a negative pressure effect in the diffuser chamber 6132, further enhancing the negative pressure at the low-pressure port 62.

[0109] In some embodiments, please refer to Figure 6 As shown, the low-pressure generating chamber 613 also includes a second contraction chamber 6133 and an expansion chamber 6134. The second contraction chamber 6133 is fluidly connected to the end of the diffusion chamber 6132 opposite to the first opening 611, and the expansion chamber 6134 is fluidly connected to the end of the second contraction chamber 6133 opposite to the first opening 611. The second contraction chamber 6133 is a chamber whose cross-sectional area gradually decreases along the direction of fluid flow and can be shaped like a frustum of a cone. The expansion chamber 6134 is a chamber whose cross-sectional area gradually increases along the direction of fluid flow and can also be shaped like a frustum of a cone. It can be understood that the second contraction chamber 6133 and the expansion chamber 6134 form a Laval tube, which accelerates the gas flowing out of the diffusion chamber 6132, increases the flow velocity of the gas through the low-pressure generator 6, and further enhances the negative pressure at the low-pressure port 62.

[0110] In some embodiments, please refer to Figure 6 As shown, the low-pressure generator 6 also includes a silencer 63, which is disposed in the first opening 611. The silencer 63 can be a sound-absorbing sheet, sound-absorbing cotton, etc. By disposing of the silencer 63 in the first opening 611, the noise generated when the low-pressure generator 6 draws air into the external environment through the first opening 611 can be reduced, thus reducing adverse effects on surrounding personnel. Optionally, the silencer 63 is embedded in the inner wall of the first opening 611 and covers the first opening 611. It is understood that the silencer 63 is gas permeable.

[0111] In some embodiments, please refer to Figure 5 As shown, the air intake 71 is in fluid communication with the second opening 612, for example, through a pipe. Thus, a single air source device 7 can be used to drive the low-pressure generator 6 and supply air to the telescopic air bag 41, eliminating the need for an additional air pump, reducing the number of air source devices 7, lowering production costs, and reducing energy consumption.

[0112] Based on the same inventive concept, this application also provides a massage device (not shown), which includes a massage mechanism 100. The massage device possesses the structural features and beneficial effects of the massage mechanism 100, which will not be elaborated here. Massage devices include, but are not limited to, massage chairs, neck massagers, waist massagers, eye massagers, foot massagers, and car seats.
