Description

Technical Field

[0001] This specification relates to a massage module for a massage machine for massaging the human body, and more specifically, to a massage module for a massage machine that enables the massage rollers to operate in multiple working modes and reduces the degree of decrease in acupressure effect even after repeated use. Background Technology

[0002] Unless otherwise stated in this specification, the content described in this section is not prior art to the claims of this application, and is not considered prior art even if included in this section.

[0003] In reality, most modern people suffer from various spinal diseases due to a variety of factors, including incorrect posture while studying or working, bad lifestyle habits, injuries caused by strenuous leisure activities, injuries caused by traffic accidents, insufficient exercise, and aging.

[0004] Spinal diseases commonly experienced by modern people include various conditions such as cervical / lumbar disc herniation (commonly known as cervical / lumbar disc herniation), spinal fractures, anterior vertebral dysplasia, spinal dysplasia, scoliosis, and cervical / lumbar strain. If these spinal diseases are not treated promptly, the pain can become very severe, significantly impacting daily life.

[0005] Therefore, the trend is towards developing and commercializing therapeutic devices with various forms and functions to prevent spinal diseases or alleviate or treat pain caused by spinal diseases at home. In particular, recently, a massage machine that can perform various physical or thermal therapies on the entire spine, including the cervical, thoracic, and lumbar vertebrae, while the user is lying down has gained attention through various media and is now available on the market.

[0006] Massagers are typically constructed by mounting a massage module inside a bed-shaped main body. The massage module is designed to be installed in the main body in a manner that allows it to reciprocate linearly along the length of the main body, and includes massage components such as rollers, ceramic parts, or acupressure balls.

[0007] In this type of massage machine, the massage components that rise and fall with the operation of the massage module stimulate the user's body, thereby providing a massage.

[0008] In this context, existing massage modules for massage machines, due to their fixed acupressure intensity and simple, repetitive operation, become less sensitive to the same simple, repetitive stimulation after several uses. Therefore, existing massage modules for massage machines suffer from a decrease in massage effectiveness. Summary of the Invention

[0009] (The problem the invention aims to solve)

[0010] The present invention was created to solve the problems described above, and its object is to provide a massage module for a massage machine that enables the massage roller to operate in multiple working modes and reduces the degree of decrease in acupressure effect even after repeated use.

[0011] (The measures taken to solve the problem)

[0012] The massage module for a massager according to an embodiment of the present invention includes: a first driving unit, a first conversion gear, and a first driven unit. The first driving unit includes: a first driving cam configured to rotate together with a driving rotating disk that rotates by a driving force; a first driving rotating part configured to rotate together with the rotation of the first driving cam; a first driving connecting rod connected to the first driving cam such that the height of the first driving connecting rod changes with the rotation of the first driving cam; and a first driving massage roller connected to the first driving connecting rod. The first conversion gear meshes with gear teeth formed on the first driving rotating part and rotates together with the rotation of the first driving rotating part. The first driven unit includes: a first driven rotating part meshing with gear teeth formed on the outer surface of the first conversion gear; a first driven cam configured to rotate together with the rotation of the first driven rotating part; a first driven connecting rod connected to the first driven cam such that the height of the first driven connecting rod changes with the rotation of the first driven cam; and a first driven massage roller connected to the first driven connecting rod.

[0013] Furthermore, in the embodiments of the present invention, the massage module for the massage machine switches between a first working mode and a second working mode as the rotation direction of the drive rotating disk changes. In the first working mode, the first drive massage roller and the first driven massage roller work in the same direction, while in the second working mode, the first drive massage roller and the first driven massage roller work in different directions.

[0014] Furthermore, in the first operating mode, the first driving cam protrusion of the first driving cam and the first driven cam protrusion of the first driven cam rotate in the same phase as each other, while in the second operating mode, the first driving cam protrusion of the first driving cam and the first driven cam protrusion of the first driven cam rotate in different phases.

[0015] In addition, the first conversion gears are respectively inserted into the first drive conversion hole formed along the circumference of the first drive rotating part and the first driven conversion groove formed along the circumference of the first driven rotating part. The size of the first drive conversion hole can be formed to be smaller than the size of the first driven conversion groove.

[0016] In addition, in the first working mode, the first conversion gear can be located on one side of the first drive conversion hole and one side of the first driven conversion slot and rotate together with the first drive rotating part and the first driven rotating part. In the second working mode, the first conversion gear can be located on the other side of the first drive conversion hole and the other side of the first driven conversion slot and rotate together with the first drive rotating part and the first driven rotating part.

[0017] Furthermore, if the rotation direction of the drive rotary disk changes in the first operating mode, during the rotational movement of the first conversion gear from one side of the first drive conversion hole to the other side of the first drive conversion hole, the first conversion gear can also rotate from one side of the first driven conversion groove to the other side of the first driven conversion groove. During the rotational movement of the first conversion gear from one side of the first driven conversion groove to the other side of the first driven conversion groove, the first driven rotating part stops rotating, and a phase difference is generated between the first drive cam protrusion of the first drive cam and the first driven cam protrusion of the first driven cam, thereby enabling the conversion from the first operating mode to the second operating mode.

[0018] Furthermore, the massage module for the massage machine in the embodiments of the present invention further includes a bearing portion, the bearing portion including: a first drive cam bearing disposed at the lower part of the first drive cam and having a first drive cam lubrication groove for filling with lubricating oil; and a first drive rotary bearing disposed at the lower part of the first drive rotary portion and having a first drive rotary lubrication groove for filling with lubricating oil.

[0019] Furthermore, the massage module for a massage machine according to an embodiment of the present invention further includes a housing that accommodates the first driving part and the first driven part. A first driving constraint hole is formed on one side of the housing for inserting a first driving connecting rod constraint member, and a first driving connection hole is formed on the first driving connecting rod for inserting the first driving connecting rod constraint member.

[0020] Furthermore, the massage module for a massage machine according to an embodiment of the present invention further includes: a housing that accommodates the first driving part and the first driven part; and a drive gear disposed outside the first driving part and the first driven part and rotating together with the first drive rotating part. A drive exposure hole is formed in the lower part of the housing, exposing a portion of the drive gear to the outside of the housing.

[0021] Furthermore, the massage module for a massager according to an embodiment of the present invention further includes: a housing that houses the first driving part and the first driven part, and has a window for identifying the first driven cam; and a rotation recognition sensor that senses the rotational state of the first driving part and the first driven part by sensing a first magnet attached to the first driven cam.

[0022] Furthermore, the massage module for the massage machine in the embodiments of the present invention further includes a drive transmission section, a second drive section, a second conversion gear, and a second driven section. The drive transmission section includes: a drive gear disposed outside the first drive section and the first driven section and rotating together with the first driven rotating section; and a driven gear meshing with the drive gear and rotating in a direction opposite to the rotation direction of the drive gear as the drive gear rotates. The second drive section includes: a second drive rotating section configured to rotate together with the driven gear; a second drive cam configured to rotate together with the second drive rotating section; and a second drive connecting rod connected to the second drive cam to cause the upper... The height of the second drive connecting rod changes with the rotation of the second drive cam; and a second drive massage roller is connected to the second drive connecting rod. The second conversion gear meshes with the gear teeth formed on the second drive rotating part and rotates together with the rotation of the second drive rotating part. The second driven part includes: a second driven rotating part that meshes with the gear teeth formed on the outer surface of the second conversion gear; a second driven cam configured to rotate together with the rotation of the second driven rotating part; a second driven connecting rod connected to the second driven cam such that the height of the second driven connecting rod changes with the rotation of the second driven cam; and a second driven massage roller connected to the second driven connecting rod.

[0023] Furthermore, in embodiments of the present invention, the massage module for the massage machine switches between a first working mode and a second working mode as the rotation direction of the drive rotating disk changes. In the first working mode, the first drive massage roller, the first driven massage roller, the second drive massage roller, and the second driven massage roller all work in the same direction. In the second working mode, the first drive massage roller and the second drive massage roller all work in the same direction, as do the first driven massage roller and the second driven massage roller.

[0024] (The effect of the invention)

[0025] As described above, the massage module for a massager of the present invention enables the massage roller to operate in multiple working modes, thereby achieving the advantage of improving the acupressure effect even after repeated use.

[0026] The effects of this invention are not limited to those mentioned above, and those skilled in the art will clearly understand other effects not mentioned from the description of the claims. Attached Figure Description

However, the present invention can be embodied in various different ways and is not limited to the embodiments described herein.

[0049] Figure 1 This is a front perspective view of a massage module for a massage machine according to an embodiment of the present invention. Figure 2 This is a low-view perspective view of a massage module for a massage machine according to an embodiment of the present invention. Figure 1 and Figure 2 The first direction FD shown refers to the direction from which the housing 900 is viewed from the side where the rotation recognition sensor 1000 is located.

[0050] Reference Figure 1 and Figure 2The massage module 1 for a massager according to an embodiment of the present invention is used for massaging the human body (e.g., the back). The massage module 1 for a massager according to an embodiment of the present invention can rise or fall on the lower part of the human back to massage the human body.

[0051] The massage module 1 for a massage machine according to an embodiment of the present invention includes: a first drive unit 100, a first conversion gear 200, a first driven unit 300, a drive gear 400, a second drive unit 500, a second conversion gear 600, a second driven unit 700, a driven gear 800, a housing 900, a rotation recognition sensor 1000, and a bearing unit 1100. However, the constituent elements of the massage module 1 for a massage machine according to an embodiment of the present invention are not limited thereto, and constituent elements of the embodiment may be added or at least one constituent element may be omitted.

[0052] On the other hand, a massage module 1 for a massage machine according to an embodiment of the present invention includes four drive units 100, 300, 500 and 700, but this is just an example. As long as it can work in the first working mode and the second working mode, it may also include two or more drive units.

[0053] Figure 3 This is an exploded perspective view of a massage module for a massage machine according to an embodiment of the present invention. Figure 4 This is an exploded perspective view of the first drive unit, the first driven unit, the first conversion gear, and the drive gear in a massage module for a massage machine according to an embodiment of the present invention.

[0054] Reference Figures 1 to 3 The first drive unit 100 is located at a certain position in the housing 900 and rotates and moves linearly to massage the human body. The first drive unit 100 can rotate about the first rotation axis 30.

[0055] Reference Figure 3 and Figure 4 The first drive unit 100 includes: a first drive cam 110, a first drive rotating part 120, a first drive connecting rod 130, a first drive massage roller 140, and a first drive guide component 150.

[0056] The first drive cam 110 is configured to interact with the drive rotary disk 10 (shown in the figure) which is rotated by a driving force. Figure 3 The first drive cam 110 rotates together with the drive rotating disk 10. A drive groove is formed on one side of the first drive cam 110 for the drive protrusion (not shown) of the drive rotating disk 10 to insert into. With the drive protrusion of the drive rotating disk 10 inserted into the drive groove, the first drive cam 110 rotates together with the drive rotating disk 10. The drive rotating disk 10 rotates under the action of a power generation unit 10a for generating driving force. The power generation unit 10a includes a motor and can cooperate with a mating part 10b (shown in...). Figure 3 The mating part 10b is configured to enclose at least a portion of the power generating part 10a. The first drive cam 110 is formed in an overall asymmetrical shape centered on the first rotation axis 30.

[0057] The first drive cam 110 includes: a first drive cam body 111, a first drive cam protrusion 112 protruding from the first drive cam body 111 toward the first drive rotation part 120, and a first drive cam rotary disk 113 disposed at a position from the first drive cam body 111 toward the power generation part 10a. A drive groove is formed in the first drive cam rotary disk 113 for the drive protrusion of the drive rotary disk 10 to be inserted. The first drive cam body 111, the first drive cam protrusion 112, and the first drive cam rotary disk 113 can be integrally formed. The first drive cam body 111 is formed in a size larger than the first drive cam protrusion 112 and smaller than the first drive cam rotary disk 113.

[0058] The first drive rotating part 120 is configured to rotate together with the rotation of the first drive cam 110. The first rotating shaft 30 can be inserted into the center of the first drive rotating part 120, and the first drive rotating part 120 rotates about the first rotating shaft 30.

[0059] The first drive rotating part 120 has a first drive cam protrusion insertion groove 120a for the first drive cam protrusion 112 to be inserted. When the first drive cam protrusion 112 is inserted into the first drive cam protrusion insertion groove 120a, the first drive rotating part 120 can rotate together with the rotation of the first drive cam 110.

[0060] At least a portion of the inner circumferential surface of the first drive rotating part 120 is formed with gear teeth that mesh with the first conversion gear 200.

[0061] A first drive gear protrusion insertion groove 120b is formed on the outer surface of the first drive rotating part 120 for inserting drive gear protrusions 410 protruding from the inner circumferential surface of the drive gear 400. When the drive gear protrusions 410 are inserted into the first drive gear protrusion insertion groove 120b, if the first drive rotating part 120 rotates, the drive gear 400 rotates together. Multiple drive gear protrusions 410 can protrude from the inner circumferential surface of the drive gear 400; in this case, multiple first drive gear protrusion insertion grooves 120b can be formed on the outer surface of the first drive rotating part 120.

[0062] The first drive connecting rod 130 is connected to the first drive cam 110, causing the height of the first drive connecting rod 130 to change with the rotation of the first drive cam 110. The first drive connecting rod 130 has a first drive connecting hole 130a for inserting the first drive connecting rod constraint member 150a, and also has a first drive cam insertion hole 130b for inserting the first drive cam body 111. The first drive connecting hole 130a can extend in the vertical direction.

[0063] The first drive massage roller 140 is connected to the first drive connecting rod 130. The upper part of the first drive massage roller 140 is connected to the first drive connecting rod 130. One side and the other side of the first drive massage roller 140 can be formed into shapes that are the same size or different sizes. The first drive massage roller 140 is rotatably coupled to the first drive massage roller support 140a. The first drive massage roller support 140a is connected to the first drive connecting rod 130.

[0064] The first drive guide member 150 is configured to cover the outside of the first drive connecting rod 130. The first drive guide member 150 can be formed in an elliptical ring shape. Holes for the first drive connecting rod restraint member 150a to pass through can be formed on one side and the other side of the first drive guide member 150.

[0065] Reference Figure 4 The first conversion gear 200 meshes with the gear teeth formed on the inner circumferential surface of the first drive rotating part 120 and rotates together with the first drive rotating part 120. One side of the first conversion gear 200 is inserted into the first drive conversion hole 121 formed along the circumference of the first drive rotating part 120. If the first drive rotating part 120 rotates, the first conversion gear 200 moves and rotates along the first drive conversion hole 121. If the first conversion gear 200 is located on one side of the first drive conversion hole 121 and is supported by the first drive rotating part 120, the first conversion gear 200 can rotate together with the first drive rotating part 120.

[0066] Reference Figures 1 to 3 The first driven part 300 is located at a certain position in the housing 900 and can rotate and move linearly to massage the human body. The first driven part 300 can rotate about the first rotation axis 30.

[0067] Reference Figure 3 and Figure 4 The first driven part 300 includes: a first driven cam 310, a first driven rotating part 320, a first driven connecting rod 330, a first driven massage roller 340, and a first driven guide member 350.

[0068] The first driven cam 310 is configured to rotate together with the first driven rotating part 320. The first rotating shaft 30 can be inserted into the first driven cam 310, and the first driven cam 310 is formed in an overall asymmetrical shape with the first rotating shaft 30 as the center.

[0069] The first driven cam 310 includes: a first driven cam body 311, a first driven cam protrusion 312 protruding from the first driven cam body 311 toward the first driven rotating part 320, and a first driven cam rotary disk 313 disposed at a position facing outward from the first driven cam body 311. The first driven cam body 311, the first driven cam protrusion 312, and the first driven cam rotary disk 313 can be integrally formed. The first driven cam body 311 is formed in a size larger than the first driven cam protrusion 312 and smaller than the first driven cam rotary disk 313.

[0070] The first driven rotating part 320 has a first driven cam protrusion insertion groove 320a for the first driven cam protrusion 312 to be inserted. When the first driven cam protrusion 312 is inserted into the first driven cam protrusion insertion groove 320a, the first driven cam 310 can rotate together with the rotation of the first driven rotating part 320.

[0071] The first driven rotating part 320 meshes with gear teeth formed on the outer surface of the first conversion gear 200. Gear teeth that mesh with the first conversion gear 200 are formed on the outer surface of the central shaft of the first driven rotating part 320. A first rotating shaft 30 can be inserted into the center of the first driven rotating part 320, and the first driven rotating part 320 rotates around the first rotating shaft 30.

[0072] A first driven rotating portion 320 is formed with a first driven conversion groove 321 for insertion into the other side of the first conversion gear 200. The first driven conversion groove 321 is formed circumferentially along the first driven rotating portion 320. The first conversion gear 200 rotates together with the first driving rotating portion 120, and while the first conversion gear 200 moves along the first driven conversion groove 321, the first driven rotating portion 320 remains stationary. When the first conversion gear 200 is located on one side or the other side of the first driven conversion groove 321 and is supported by the first driven rotating portion 320, the first driven rotating portion 320 rotates together with the first conversion gear 200 rotating about the first rotating axis 30.

[0073] The size of the first driven conversion slot 321 is larger than the size of the first drive conversion hole 121. When switching between the first operating mode AM and the second operating mode ZM, the first conversion gear 200 can rotate from one side of the first driven conversion slot 321 to the other side while rotating from one side of the first drive conversion hole 121 to the other side. For this purpose, the ratio of the gear teeth on the inner circumferential surface of the first drive rotating part 120 to the gear teeth on the outer surface of the first conversion gear 200 is set to be different, and the rotational speed of the first conversion gear 200 is set to be faster than the rotational speed of the first drive rotating part 120.

[0074] The first driven rotating part 320 is arranged in a manner surrounded by the drive gear 400, but even if the drive gear 400 rotates, the first driven rotating part 320 will not rotate. That is, the drive gear 400 idles relative to the first driven rotating part 320.

[0075] The first driven connecting rod 330 is connected to the first driven cam 310, causing the height of the first driven connecting rod 330 to change with the rotation of the first driven cam 310. The first driven connecting rod 330 has a first driven connecting hole 330a for inserting the first driven connecting rod restraint member 350a, and a first driven cam insertion hole 330b for inserting the first driven cam body 311 of the first driven cam 310. The first driven connecting hole 330a can extend in the vertical direction.

[0076] The first driven massage roller 340 is connected to the first driven connecting rod 330. The first driven massage roller 340 is connected to the upper part of the first driven connecting rod 330. One side and the other side of the first driven massage roller 340 can be formed into shapes that are the same size or different sizes. The first driven massage roller 340 is rotatably coupled to the first driven massage roller support 340a. The first driven massage roller support 340a is connected to the first driven connecting rod 330.

[0077] The first driven guide member 350 is configured to cover the outside of the first driven connecting rod 330. The first driven guide member 350 can be formed in an elliptical ring shape. Holes for the first driven connecting rod restraint member 350a to pass through are formed on one side and the other side of the first driven guide member 350.

[0078] The massage module 1 for a massage machine according to an embodiment of the present invention may include a drive transmission unit. The drive transmission unit is responsible for transmitting power from the first drive unit 100 to the second drive unit 500. The drive transmission unit includes a drive gear 400 and a driven gear 800 that mesh with each other and rotate. The driven gear 800 will be described in detail later.

[0079] Reference Figure 3 and Figure 4 The drive gear 400 is disposed outside the first drive part 100 and the aforementioned first driven part 300, and rotates together with the first drive rotating part 120. A plurality of gear teeth are formed on the outer surface of the drive gear 400.

[0080] Figure 5 This is an exploded perspective view of the second drive unit, the second driven unit, the second conversion gear, and the driven gear in a massage module for a massage machine according to an embodiment of the present invention.

[0081] Reference Figures 1 to 5 The second drive unit 500 is located at a certain position in the housing 900 and rotates and moves linearly to massage the human body. The second drive unit 500 can rotate about the second rotation axis 50.

[0082] Reference Figure 3 and Figure 5 The second drive unit 500 includes: a second drive cam 510, a second drive rotating part 520, a second drive connecting rod 530, a second drive massage roller 540, and a second drive guide member 550.

[0083] The second drive cam 510 is configured to rotate together with the second drive rotating part 520. The second rotating shaft 50 is inserted into the second drive cam 510, and the second drive cam 510 is formed in an overall asymmetrical shape with the second rotating shaft 50 as the center.

[0084] The second drive cam 510 includes: a second drive cam body 511, a second drive cam protrusion 512 protruding from the second drive cam body 511 toward the second drive rotation part 520, and a second drive cam rotary disk 513 disposed at a position facing outward from the second drive cam body 511. The second drive cam body 511, the second drive cam protrusion 512, and the second drive cam rotary disk 513 can be integrally formed. The second drive cam body 511 is formed in a size larger than the second drive cam protrusion 512 and smaller than the second drive cam rotary disk 513.

[0085] The second drive rotating part 520 is configured to rotate together with the driven gear 800. That is, if the driven gear 800 meshes with the drive gear 400 and rotates, the second drive rotating part 520 rotates together with the driven gear 800. The second rotating shaft 50 can be inserted into the center of the second drive rotating part 520, and the second drive rotating part 520 rotates around the second rotating shaft 50.

[0086] A second drive gear protrusion insertion groove 520b, protruding from the inner circumferential surface of the driven gear 800, is formed on the outer surface of the second drive rotating part 520 for the driven gear protrusion 810 to be inserted. When the driven gear protrusion 810 is inserted into the second drive gear protrusion insertion groove 520b, if the driven gear 800 rotates, the second drive rotating part 520 rotates together. Multiple driven gear protrusions 810 can protrude from the inner circumferential surface of the driven gear 800; in this case, multiple second drive gear protrusion insertion grooves 520b can be formed on the outer surface of the second drive rotating part 520.

[0087] The second drive rotating part 520 has a second drive cam protrusion insertion groove 520a for the second drive cam protrusion 512 to be inserted. When the second drive cam protrusion 512 is inserted into the second drive cam protrusion insertion groove 520a, the second drive cam 510 can rotate together with the rotation of the second drive rotating part 520.

[0088] At least a portion of the inner circumferential surface of the second drive rotating part 520 is formed with gear teeth that mesh with the second conversion gear 600.

[0089] The second drive connecting rod 530 is connected to the second drive cam 510, causing the height of the second drive connecting rod 530 to change with the rotation of the second drive cam 510. The second drive connecting rod 530 has a second drive connecting hole 530a for inserting the second drive connecting rod constraint member 550a, and also has a second drive cam insertion hole 530b for inserting the second drive cam body 511. The second drive connecting hole 530a can extend in the vertical direction.

[0090] The second drive massage roller 540 is connected to the second drive connecting rod 530. The upper part of the second drive massage roller 540 is connected to the second drive connecting rod 530. One side of the second drive massage roller 540 and the other side of the second drive massage roller 540 can be formed into shapes that are the same size or different sizes. The second drive massage roller 540 is rotatably coupled to the second drive massage roller support 540a. The second drive massage roller support 540a is connected to the second drive connecting rod 530.

[0091] The second drive guide member 550 is configured to cover the outside of the second drive connecting rod 530. The second drive guide member 550 can be formed in an elliptical ring shape. Holes for the second drive connecting rod restraint member 550a to pass through are formed on one side and the other side of the second drive guide member 550.

[0092] Reference Figure 5The second conversion gear 600 meshes with the gear teeth formed on the inner circumferential surface of the second drive rotating part 520 and rotates together with the second drive rotating part 520. One side of the second conversion gear 600 is inserted into a second drive conversion hole formed circumferentially along the second drive rotating part 520. If the second drive rotating part 520 rotates, the second conversion gear 600 moves and rotates along the second drive conversion hole. If the second conversion gear 600 is located on one side of the second drive conversion hole and supported by the second drive rotating part 520, the second conversion gear 600 can rotate together with the second drive rotating part 520.

[0093] Reference Figures 1 to 5 The second driven part 700 is located at a certain position in the housing 900 and can rotate and move linearly to massage the human body. The second driven part 700 can rotate about the second rotation axis 50.

[0094] Reference Figure 3 and Figure 5 The second driven part 700 includes: a second driven cam 710, a second driven rotating part 720, a second driven connecting rod 730, a second driven massage roller 740, and a second driven guide member 750.

[0095] The second driven cam 710 is configured to rotate together with the second driven rotating part 720. The second rotating shaft 50 can be inserted into the second driven cam 710, and the second driven cam 710 is formed in an overall asymmetrical shape with the second rotating shaft 50 as the center.

[0096] The second driven cam 710 includes: a second driven cam body 711, a second driven cam protrusion 712 protruding from the second driven cam body 711 toward the second driven rotating portion 720, and a second driven cam rotary disk 713 disposed at a position facing outward from the second driven cam body 711. The second driven cam body 711, the second driven cam protrusion 712, and the second driven cam rotary disk 713 can be integrally formed. The second driven cam body 711 is formed in a size larger than the second driven cam protrusion 712 and smaller than the second driven cam rotary disk 713.

[0097] The second driven rotating part 720 is provided with a second driven cam protrusion insertion groove 720a for the second driven cam protrusion 712 to be inserted. When the second driven cam protrusion 712 is inserted into the second driven cam protrusion insertion groove 720a, the second driven cam 710 can rotate together with the rotation of the second driven rotating part 720.

[0098] The second driven rotating part 720 meshes with gear teeth formed on the outer surface of the second conversion gear 600. Gear teeth that mesh with the second conversion gear 600 are formed on the outer surface of the central shaft of the second driven rotating part 720. A second rotating shaft 50 can be inserted into the center of the second driven rotating part 720, and the second driven rotating part 720 rotates around the second rotating shaft 50.

[0099] A second driven rotating part 720 is formed with a second driven conversion groove into which the other side of the second conversion gear 600 is inserted. The second driven conversion groove is formed along the circumference of the second driven rotating part 720. The second conversion gear 600 rotates together with the second driving rotating part 520, and while the second conversion gear 600 moves along the second driven conversion groove, the second driven rotating part 720 remains stationary. When the second conversion gear 600 is located on one side or the other side of the second driven conversion groove and is supported by the second driven rotating part 720, the second driven rotating part 720 rotates together with the second conversion gear 600 rotating about the second rotating axis 50.

[0100] The size of the second driven conversion slot is larger than the size of the second drive conversion hole. When switching between the first operating mode AM and the second operating mode ZM, the second conversion gear 600 can rotate from one side of the second driven conversion slot to the other side while rotating from one side of the second drive conversion hole to the other. For this purpose, the ratio of the gear teeth on the inner circumferential surface of the second drive rotating part 520 to the gear teeth on the outer surface of the second conversion gear 600 is set to be different, and the rotational speed of the second conversion gear 600 is set to be faster than the rotational speed of the second drive rotating part 520.

[0101] The second driven rotating part 720 is arranged to be surrounded by the driven gear 800, but even if the driven gear 800 rotates, the second driven rotating part 720 will not rotate. That is, the driven gear 800 idles relative to the second driven rotating part 720.

[0102] The second driven connecting rod 730 is connected to the second driven cam 710, causing the height of the second driven connecting rod 730 to change with the rotation of the second driven cam 710. The second driven connecting rod 730 has a second driven connecting hole 730a for inserting the second driven connecting rod restraint member 750a, and a second driven cam insertion hole 730b for inserting the second driven cam body 711 of the second driven cam 710. The second driven connecting hole 730a can extend in the vertical direction.

[0103] The second driven massage roller 740 is connected to the second driven connecting rod 730. The upper part of the second driven massage roller 740 is connected to the second driven connecting rod 730. One side of the second driven massage roller 740 and the other side of the second driven massage roller 740 can be formed into shapes that are the same size or different sizes. The second driven massage roller 740 is rotatably coupled to the second driven massage roller support 740a. The second driven massage roller support 740a is connected to the second driven connecting rod 730.

[0104] The second driven guide member 750 is configured to cover the outside of the second driven connecting rod 730. The second driven guide member 750 can be formed in an elliptical ring shape. Holes for the second driven connecting rod restraint member 750a to pass through are formed on one side and the other side of the second driven guide member 750.

[0105] Reference Figure 3 and Figure 5 The driven gear 800 is disposed outside the second drive unit 500 and the aforementioned second driven unit 700, and rotates together with the second drive rotating unit 520. The driven gear 800 rotates in the opposite direction to the drive gear 400. A plurality of gear teeth are formed on the outer surface of the driven gear 800.

[0106] Figure 6 (a) to Figure 6 (c) is a diagram illustrating an example of adjusting the height of the first drive connecting rod by rotating the first drive cam.

[0107] Reference Figure 6 (a) to Figure 6 (c) The process of adjusting the height of the first drive connecting rod 130 using the first drive cam 110 is described.

[0108] First, such as Figure 6 As shown in (a), when the first drive cam 110 is in a certain position, if the drive rotary disk 10 rotates in one direction, the first drive cam 110 will also rotate.

[0109] Next, as Figure 6 As shown in (b), if the first drive cam 110 rotates in one direction, the height of the first drive cam protrusion 112 will decrease. Since the first drive cam 110 has an asymmetrical shape with respect to the first rotation axis 30, the center of the first drive cam 110 will become lower with respect to the height 30H of the first rotation axis 30. Consequently, the height of the first drive connecting rod 130 decreases, and the height of the first drive massage roller 140 also decreases.

[0110] Next, as Figure 6As shown in (c), if the first drive cam 110 rotates further in one direction, the height of the first drive cam protrusion 112 will increase. In this case, the center of the first drive cam 110 will become higher, with the height 30H of the first rotation axis 30 as a reference. Consequently, the height of the first drive connecting rod 130 increases, and the height of the first drive massage roller 140 also increases.

[0111] As can be seen from the above description, the position of the first drive cam protrusion 112 is related to the height of the first drive connecting rod 130. Furthermore, those skilled in the art will readily understand that the process of adjusting the height of the first drive connecting rod 130 using the first drive cam 110 as described above is also readily applicable to the first driven part 300, the second drive part 500, and the second driven part 700.

[0112] Figure 7 (a) and Figure 7 (b) is a diagram showing the working state of the first working mode as viewed from a first direction in the massage module for a massage machine according to an embodiment of the present invention. Figure 8 (a) and Figure 8 (b) is a diagram showing the working state of the second working mode in a massage module for a massage machine according to an embodiment of the present invention, viewed from a first direction.

[0113] In an embodiment of the present invention, the massage module 1 for a massage machine can switch between a first working mode AM (Align Mode) and a second working mode ZM (Zigzag Mode) according to the rotation direction of the drive rotating disk 10.

[0114] Therefore, the massage module 1 for a massager according to embodiments of the present invention can massage the human body in multiple modes, thus achieving the advantage of enhancing the acupressure effect through multiple stimuli. Furthermore, the massage module 1 for a massager according to embodiments of the present invention can achieve mode switching through a relatively easy operation of changing the rotation direction of the drive rotating disk 10, thereby improving the ease of mode switching.

[0115] The following is for reference Figure 7 (a) and Figure 7 (b) The operating state of the first operating mode AM according to an embodiment of the present invention is described. On the other hand, Figure 7 (a) and Figure 7 (b) The rotation direction markings shown are not intended to indicate that the first operating mode operates only in a specific rotation direction, but should be understood as being shown to distinguish the rotation direction from that of the second operating mode.

[0116] According to one embodiment, in the first operating mode AM, the first drive massage roller 140 and the first driven massage roller 340 can operate in the same direction. As an example, in the first operating mode AM, the first drive massage roller 140 and the first driven massage roller 340 can rotate at the same height. As another example, in the first operating mode AM, the first drive massage roller 140 and the first driven massage roller 340 can rise or fall together. For this purpose, the first drive cam protrusion 112 and the first driven cam protrusion 312 can rotate at the same height (phase). That is, when viewed from the first direction FD, the first drive cam protrusion 112 and the first driven cam protrusion 312 can rotate in an overlapping configuration in the first operating mode AM. Figure 7 (a) and Figure 7 As shown in (b), in the first operating mode AM, the first drive cam protrusion 112 and the first driven cam protrusion 312 are able to rotate with the same height at all times.

[0117] According to one embodiment, in the first operating mode AM, the first drive massage roller 140, the first driven massage roller 340, the second drive massage roller 540, and the second driven massage roller 740 can all operate in the same direction. As an example, the first drive massage roller 140, the first driven massage roller 340, the second drive massage roller 540, and the second driven massage roller 740 can rotate at the same height. As another example, the first drive massage roller 140, the first driven massage roller 340, the second drive massage roller 540, and the second driven massage roller 740 can rise or fall together. For this purpose, the first drive cam protrusion 112, the first driven cam protrusion 312, the second drive cam protrusion 512, and the second driven cam protrusion 712 can rotate at the same height (phase). That is, when viewed from the first direction FD, the first drive cam protrusion 112 and the first driven cam protrusion 312 can rotate in an overlapping configuration in the first operating mode AM. Furthermore, when viewed from the first direction FD, the second drive cam protrusion 512 and the second driven cam protrusion 712 can rotate in an overlapping state in the first operating mode AM. For example... Figure 7 (a) and Figure 7 As shown in (b), in the first operating mode AM, the first drive cam protrusion 112, the first driven cam protrusion 312, the second drive cam protrusion 512, and the second driven cam protrusion 712 can rotate with the same height at all times.

[0118] On the other hand, in the first operating mode AM, with the connecting rod constraint components 150a, 350a, 550a, and 750a respectively inserted into the connecting holes 130a, 330a, 530a, and 730a, the heights of the connecting rods 130, 330, 530, and 730 can be changed. These will be explained separately below.

[0119] With the first drive connecting rod constraint member 150a inserted into the first drive connecting hole 130a and the first drive constraint hole 912 of the housing 900, the height of the first drive connecting rod 130 can be changed with the first drive connecting rod 130 constrained by the first drive connecting rod constraint member 150a.

[0120] Furthermore, when the first driven connecting rod constraint member 350a is inserted into the first driven connecting hole 330a and the first driven constraint hole 913 of the housing 900, the height of the first driven connecting rod 330 can be changed in a state where the first driven connecting rod 330 is constrained by the first driven connecting rod constraint member 350a.

[0121] Furthermore, when the second drive connecting rod constraint member 550a is inserted into the second drive connecting hole 530a and the second drive constraint hole 914 of the housing 900, the height of the second drive connecting rod 530 can be changed in the state where the second drive connecting rod 530 is constrained by the second drive connecting rod constraint member 550a.

[0122] Furthermore, when the second driven connecting rod constraint member 750a is inserted into the second driven connecting hole 730a and the second driven constraint hole 915 of the housing 900, the height of the second driven connecting rod 730 can be changed in a state where the second driven connecting rod 730 is constrained by the second driven connecting rod constraint member 750a.

[0123] Thus, in the first working mode AM, the massage module 1 for the massage machine of the embodiment of the present invention uses the connecting rod constraint components 150a, 350a, 550a, and 750a to restrict the movement of each connecting rod 130, 330, 530, and 730 within a specified range, thereby stabilizing the operation of each massage roller 140, 340, 540, and 740.

[0124] The following is for reference Figure 8 (a) and Figure 8 (b) The operating state of the second operating mode ZM according to an embodiment of the present invention is described. On the other hand, Figure 8 (a) and Figure 8 (b) The rotation direction markings shown are not intended to indicate that the second operating mode operates only in a specific rotation direction, but should be understood as being shown to distinguish it from the rotation direction of the first operating mode.

[0125] According to one embodiment, in the second operating mode ZM, the first driving massage roller 140 and the first driven massage roller 340 can operate in different directions. For example, when the first driving massage roller 140 rises, the first driven massage roller 340 descends.

[0126] In the second operating mode ZM, the first drive massage roller 140 and the first driven massage roller 340 can rotate at different heights. For this purpose, the first drive cam protrusion 112 and the first driven cam protrusion 312 can rotate at different heights (phases). For example, when viewed from the first direction FD, the first drive cam protrusion 112 and the first driven cam protrusion 312 can rotate with different phases in the second operating mode ZM. Figure 8 (a) and Figure 8 As shown in (b), in the second working mode ZM, the first driving cam protrusion 112 and the first driven cam protrusion 312 can rotate with a phase difference of 180 degrees.

[0127] Furthermore, in the second operating mode ZM, the second drive massage roller 540 and the second driven massage roller 740 can rotate at different heights. For this purpose, the second drive cam protrusion 512 and the second driven cam protrusion 712 can rotate at different heights (phases). For example, when viewed from the first direction FD, the second drive cam protrusion 512 and the second driven cam protrusion 712 can rotate with different phases in the second operating mode ZM. Figure 8 (a) and Figure 8 As shown in (b), in the second operating mode ZM, the second drive cam protrusion 512 and the second driven cam protrusion 712 can rotate with a phase difference of 180 degrees.

[0128] According to one embodiment, in the second working mode ZM, the first driving massage roller 140 and the second driving massage roller 540 can work in the same direction as each other, and the first driven massage roller 340 and the second driven massage roller 740 can work in the same direction as each other.

[0129] In the second operating mode ZM, the first drive massage roller 140 and the second drive massage roller 540 can rotate at the same height, and the first driven massage roller 340 and the second driven massage roller 740 can rotate at the same height as each other. For example, in the second operating mode ZM, when the first drive massage roller 140 and the second drive massage roller 540 rise together, the first driven massage roller 340 and the second driven massage roller 740 can fall together; when the first drive massage roller 140 and the second drive massage roller 540 fall together, the first driven massage roller 340 and the second driven massage roller 740 can rise together. For this purpose, the first drive cam protrusion 112 and the second drive cam protrusion 512 can rotate at the same height (phase), and the first driven cam protrusion 312 and the second driven cam protrusion 712 can rotate at the same height (phase).

[0130] On the other hand, in the second operating mode ZM, with the connecting rod constraint components 150a, 350a, 550a, and 750a respectively inserted into the connecting holes 130a, 330a, 530a, and 730a, the heights of the connecting rods 130, 330, 530, and 730 can be changed. These will be explained separately below.

[0131] With the first drive connecting rod constraint member 150a inserted into the first drive connecting hole 130a and the first drive constraint hole 912 of the housing 900, the height of the first drive connecting rod 130 can be changed in the state where the first drive connecting rod 130 is constrained by the first drive connecting rod constraint member 150a.

[0132] Furthermore, when the first driven connecting rod constraint member 350a is inserted into the first driven connecting hole 330a and the first driven constraint hole 913 of the housing 900, the height of the first driven connecting rod 330 can be changed in the state where the first driven connecting rod 330 is constrained by the first driven connecting rod constraint member 350a.

[0133] Furthermore, when the second drive connecting rod constraint member 550a is inserted into the second drive connecting hole 530a and the second drive constraint hole 914 of the housing 900, the height of the second drive connecting rod 530 can be changed in the state where the second drive connecting rod 530 is constrained by the second drive connecting rod constraint member 550a.

[0134] Furthermore, when the second driven connecting rod constraint member 750a is inserted into the second driven connecting hole 730a and the second driven constraint hole 915 of the housing 900, the height of the second driven connecting rod 730 can be changed in a state where the second driven connecting rod 730 is constrained by the second driven connecting rod constraint member 750a.

[0135] Thus, in the second working mode ZM, the massage module 1 for the massage machine of the embodiment of the present invention uses the connecting rod constraint components 150a, 350a, 550a, and 750a to restrict the movement of each connecting rod 130, 330, 530, and 730 within a specified range, thereby stabilizing the operation of each massage roller 140, 340, 540, and 740.

[0136] Figure 9 (a) and Figure 9 (c) is a diagram showing the first drive rotating part in the first operating mode as viewed from the first direction. Figure 9 (b) and Figure 9 (d) is a diagram showing the first driven rotating part in the first operating mode as viewed from the first direction.

[0137] The following is for reference Figure 9 (a) to Figure 9 (d) Explain the working state of the first driving rotating part 120 and the first driven rotating part 320 in the first working mode AM.

[0138] like Figure 9 (a) and Figure 9 As shown in (c), the first conversion gear 200 is located on one side of the first drive conversion hole 121 in the first operating mode AM. When the first conversion gear 200 is supported by the first drive support surface toward the first drive rotating part 120 or the first drive conversion hole 121, it can rotate together with the first drive rotating part 120 around the first rotating axis 30.

[0139] like Figure 9 (b) and Figure 9 As shown in (d), the first conversion gear 200 is located on one side of the first driven conversion slot 321 in the first operating mode AM. When the first conversion gear 200 is supported by the first driven support surface toward the first driven rotating part 320 or the first driven conversion slot 321, it can rotate together with the first driven rotating part 320 around the first rotating axis 30.

[0140] The following is a summary: In the first working mode AM, the first conversion gear 200 is located on one side of the first drive conversion hole 121 and one side of the first driven conversion groove 321 and is supported by the first drive rotation part 120 and the first driven rotation part 320, and can rotate together with the first drive rotation part 120 and the first driven rotation part 320.

[0141] As described above, in the first operating mode AM, the first driving cam protrusion 112 and the first driven cam protrusion 312 rotate with the same height. This is as follows: Figure 9 (a) and Figure 9As shown in (b), the first drive cam protrusion insertion slot 120a into which the first drive cam protrusion 112 is inserted and the first driven cam protrusion insertion slot 320a into which the first driven cam protrusion 312 is inserted rotate when they have the same height. Figure 9 (c) and Figure 9 (d) also shows the first drive cam protrusion insertion slot 120a and the first driven cam protrusion insertion slot 320a rotating with the same height.

[0142] The operating states of the second drive rotating part 520 and the second driven rotating part 720 in the first operating mode AM are largely the same as described above, so specific details are omitted.

[0143] Figure 10 (a) and Figure 10 (c) is a diagram showing the first drive rotating part in the second operating mode as viewed from the first direction. Figure 10 (b) and Figure 10 (d) is a diagram showing the first driven rotating part in the second operating mode as viewed from the first direction.

[0144] The following is for reference Figure 10 (a) to Figure 10 (d) Explain the working state of the first driving rotating part 120 and the first driven rotating part 320 in the second working mode ZM.

[0145] like Figure 10 (a) and Figure 10 As shown in (c), the first conversion gear 200 is located on the other side of the first drive conversion hole 121 in the second operating mode ZM. When the first conversion gear 200 is supported by a second drive support surface that is separated from the first drive rotating part 120 or the first drive support surface, it can rotate together with the first drive rotating part 120 around the first rotating axis 30.

[0146] like Figure 10 (b) and Figure 10 As shown in (d), the first conversion gear 200 is located on the other side of the first driven conversion slot 321 in the second operating mode ZM. When the first conversion gear 200 is supported by a second driven support surface that is separated from the first driven rotating part 320 or the first driven support surface, it can rotate together with the first driven rotating part 320 around the first rotating axis 30.

[0147] The following is a summary: In the second working mode ZM, the first conversion gear 200 is located on the other side of the first drive conversion hole 121 and the other side of the first driven conversion groove 321 and is supported by the first drive rotation part 120 and the first driven rotation part 320, and can rotate together with the first drive rotation part 120 and the first driven rotation part 320.

[0148] As described above, in the first operating mode AM, the first driving cam protrusion 112 and the first driven cam protrusion 312 rotate with different phases. This is as follows: Figure 10 (a) and Figure 10 As shown in (b), when viewed from the first direction FD, the first drive cam protrusion insertion slot 120a and the first driven cam protrusion insertion slot 320a are not overlapped but rotate in a state with different phases. Furthermore, from... Figure 10 (c) and Figure 10 (d) It can be seen that when viewed from the first direction FD, the first driving cam protrusion insertion slot 120a and the first driven cam protrusion insertion slot 320a are not overlapped but rotate in a state with different phases.

[0149] The operating states of the second drive rotating part 520 and the second driven rotating part 720 in the second operating mode ZM are largely the same as described above, so specific details are omitted.

[0150] Figure 11 (a) to Figure 11 (c) is a diagram showing the appearance of the first drive rotating part and the first driven rotating part as viewed from the first direction in order to illustrate the process of switching from the first operating mode to the second operating mode.

[0151] The following is for reference Figure 11 Explain the process of switching from the first working mode AM to the second working mode ZM.

[0152] First, such as Figure 11 As shown in (a), in the first working mode AM, when the first conversion gear 200 is located on one side of the first drive conversion hole 121 and one side of the first driven conversion groove 321, the rotation direction of the drive rotary disk 10 changes.

[0153] Next, as Figure 11 As shown in (b), if the drive rotating disk 10 rotates, the first drive rotating part 120 rotates together. The first conversion gear 200 meshes with the gear teeth of the first drive rotating part 120 and the gear teeth of the first driven rotating part 320 and rotates along the first drive conversion hole 121 while rotating along the first driven conversion groove 321.

[0154] In this case, the first switching gear 200 rotates and moves in a state of meshing with the gear teeth of the first driven rotating part 320, while the first driven rotating part 320 stops rotating.

[0155] Next, as Figure 11As shown in (c), if the drive rotating disk 10 rotates further, the first drive rotating part 120 rotates further together, and the first conversion gear 200 rotates and moves towards the other side of the first drive conversion hole 121 while rotating and moving to the other side of the first driven conversion groove 321.

[0156] If the first conversion gear 200 is located on the other side of the first drive conversion hole 121 and the other side of the first driven conversion groove 321, the first conversion gear 200 is supported by the first drive rotating part 120 and the first driven rotating part 320, so that it can rotate together with the first drive rotating part 120 and the first driven rotating part 320.

[0157] The process described above is used to switch from the first operating mode AM to the second operating mode ZM, and observation is performed. Figure 11 (a) shows the first driving cam protrusion insertion groove 120a and the first driven cam protrusion insertion groove 320a, and Figure 11 As shown in (c), the first drive cam protrusion insertion slot 120a and the first driven cam protrusion insertion slot 320a indicate that by switching from the first working mode AM to the second working mode ZM, the phases of the first drive cam protrusion 112 and the first driven cam protrusion 312 become different.

[0158] Figure 12 (a) to Figure 12 (c) is a diagram showing the appearance of the first drive rotating part and the first driven rotating part as viewed from the first direction in order to illustrate the process of switching from the second operating mode to the first operating mode.

[0159] The following is for reference Figure 12 Explain the process of switching from the second working mode ZM to the first working mode AM.

[0160] First, such as Figure 12 As shown in (a), in the second working mode ZM, when the first conversion gear 200 is located on the other side of the first drive conversion hole 121 and the other side of the first driven conversion groove 321, the rotation direction of the drive rotary disk 10 changes.

[0161] Next, as Figure 12 As shown in (b), if the drive rotating disk 10 rotates, the first drive rotating part 120 rotates together. The first conversion gear 200 meshes with the gear teeth of the first drive rotating part 120 and the gear teeth of the first driven rotating part 320 and rotates along the first drive conversion hole 121 while rotating along the first driven conversion groove 321.

[0162] In this case, the first switching gear 200 rotates and moves in a state of meshing with the gear teeth of the first driven rotating part 320, while the first driven rotating part 320 stops rotating.

[0163] Next, as Figure 12 As shown in (c), if the drive rotating disk 10 rotates further, the first drive rotating part 120 rotates further together, and the first conversion gear 200 rotates and moves towards one side of the first drive conversion hole 121 while rotating and moving to one side of the first driven conversion groove 321.

[0164] If the first conversion gear 200 is located on one side of the first drive conversion hole 121 and one side of the first driven conversion groove 321, the first conversion gear 200 is supported by the first drive rotating part 120 and the first driven rotating part 320, so that it can rotate together with the first drive rotating part 120 and the first driven rotating part 320.

[0165] The process described above is used to switch from the second operating mode ZM to the first operating mode AM, and observation is performed. Figure 12 (a) shows the first driving cam protrusion insertion groove 120a and the first driven cam protrusion insertion groove 320a, and Figure 12 As shown in (c), the first drive cam protrusion insertion slot 120a and the first driven cam protrusion insertion slot 320a indicate that by switching from the second working mode ZM to the first working mode AM, the phases of the first drive cam protrusion 112 and the first driven cam protrusion 312 become the same.

[0166] Figure 13 This is a diagram illustrating a rotation recognition sensor in a massage module for a massage machine according to an embodiment of the present invention.

[0167] Reference Figures 1 to 3 as well as Figure 13 The housing 900 accommodates the first driving part 100, the first driven part 300, the second driving part 500, and the second driven part 700. The housing 900 can be formed in a cuboid shape as a whole, but there is no limitation on the shape as long as it can accommodate the first driving part 100, the first driven part 300, the second driving part 500, and the second driven part 700.

[0168] The housing 900 includes an upper housing 910 and a lower housing 920.

[0169] The upper housing 910 is detachably connected to the lower housing 920. The upper housing 910 and the lower housing 920 are detachably connected to each other by a bolt-like connecting component.

[0170] The upper housing 910 has a plurality of through holes 911 through which the first drive connecting rod 130, the first driven connecting rod 330, the second drive connecting rod 530, and the second driven connecting rod 730 pass respectively (shown in...). Figure 3 ).

[0171] The upper housing 910 has a first drive constraint hole 912 for inserting the first drive connecting rod constraint member 150a, a first driven constraint hole 913 for inserting the first driven connecting rod constraint member 350a, a second drive constraint hole 914 for inserting the second drive connecting rod constraint member 550a, and a second driven constraint hole 915 for inserting the second driven connecting rod constraint member 750a.

[0172] A drive exposure hole 921 is formed in the lower housing 920, which exposes a portion of the drive gear 400 to the outside (shown in...). Figure 3 ) and a driven exposure hole 922 (shown in) that exposes a portion of the driven gear 800 to the outside. Figure 3 Therefore, the massage module 1 for a massage machine according to the embodiment of the present invention can realize a structure in which the drive gear 400 and the driven gear 800 can rotate without interference from the lower housing 920.

[0173] Reference Figure 13 A window is formed in the shell at 900.

[0174] The window may include a first window 930 that allows external identification of the first driven cam 310 and a second window 940 that allows external identification of the second drive cam 510. The first window 930 and the second window 940 may be formed in a portion of the upper housing 910 and a portion of the lower housing 920, respectively.

[0175] Reference Figure 13 A rotation recognition sensor 1000 is integrated into the housing 900. The rotation recognition sensor 1000 can sense a first magnet 3100 integrated into a first driven cam 310 and a second magnet 5100 integrated into a second drive cam 510. Thus, the massage module 1 for a massager according to an embodiment of the present invention can sense the rotational state of the first drive unit 100, the first driven unit 300, the second drive unit 500, and the second driven unit 700 by sensing the first magnet 3100 and the second magnet 5100. As an example, if the first magnet 3100 and the second magnet 5100 have the same phase, the rotation recognition sensor 1000 can sense a first operating mode AM. As another example, if the first magnet 3100 and the second magnet 5100 have different phases, the rotation recognition sensor 1000 can sense a second operating mode ZM.

[0176] A sensor module for sensing magnets can be configured on the back of the rotation recognition sensor 1000. The back of the rotation recognition sensor 1000 is the side facing the housing 900. The information recognized by the rotation recognition sensor 1000 related to the rotational states of the first drive unit 100, the first driven unit 300, the second drive unit 500, and the second driven unit 700 can be provided to a control unit (not shown) that controls the overall operation of the massage module 1 for a massage machine according to an embodiment of the present invention.

[0177] Reference Figure 13 A first retaining ring 30a may be attached to the end of the first rotating shaft 30. The first retaining ring 30a can be inserted into a groove formed at the end of the first rotating shaft 30. As a result, the first rotating shaft 30 will not detach from the first driving part 100 and the first driven part 300.
