A scraping and kneading massage mechanism

Abstract

This invention relates to a scraping and kneading massage mechanism, comprising a rotating base, at least one scraping ring and at least one kneading wheel disposed on its outer periphery. The scraping ring is composed of multiple scraping protrusions arranged at circumferential intervals and rotates synchronously with the rotating base. The kneading wheel includes a wheel body with multiple kneading protrusions on its outer periphery. A synchronously rotating transmission groove is located on the outer periphery of the rotating base. The kneading wheel body is inclined and rotates within the groove. The kneading wheel is inclined relative to the scraping ring, causing the opening and closing gap between the kneading wheel and the scraping ring to vary circumferentially. The rotating base is connected to a power drive mechanism, which drives the scraping ring to rotate. Each scraping protrusion moves circumferentially to perform scraping. Due to the contact and limitation between the kneading protrusions and the human body, the rotation of the transmission groove causes the kneading wheel to open and close, achieving opening and closing kneading. This mechanism can simultaneously perform rolling scraping and kneading massage, enriching the forms and enhancing the experience.

Description

Technical Field

[0001] This invention relates to the field of massage equipment technology, specifically a scraping and kneading massage mechanism. Background Technology

[0002] With the fast pace of life and the increasing number of people in a sub-healthy state, massage devices have become common equipment for daily muscle relaxation and relieving physical fatigue. Currently, most massage devices on the market are based on a single massage method, such as fascia guns and foam rollers, which achieve basic relaxation functions through rolling, pounding, or vibration. They are difficult to provide multiple massage experiences such as scraping and kneading at the same time, and their functions are relatively limited.

[0003] Some devices with multiple massage modes usually require multiple drive sources to control different massage mechanisms, resulting in a complex overall structure, large size, high cost, and poor transmission coordination, which affects the stability of use and the massage experience.

[0004] Therefore, how to integrate and coordinate multiple massage movements while simplifying the structure and reducing the driving source has become a problem that needs to be solved in the structural design of massage mechanism. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a scraping and kneading massage mechanism that can simultaneously perform rolling scraping and kneading massage, enriching the massage experience and enhancing the user's muscle relaxation experience.

[0006] The technical solution of the present invention: a scraping and kneading massage core, comprising a rotating base, and at least one scraping ring and at least one kneading wheel disposed on the outer periphery of the rotating base; The scraping ring is composed of multiple scraping protrusions arranged circumferentially along the outer periphery of the rotating base, and rotates synchronously with the rotating base. The kneading wheel includes a kneading wheel body, and a plurality of kneading protrusions are provided on the circumferential periphery of the kneading wheel body. The outer periphery of the rotating base is provided with a transmission groove that rotates synchronously with it. The transmission groove is inclined, and the kneading wheel is inclinedly sleeved in the transmission groove to form a rotational fit. The kneading wheel is inclined relative to the scraping ring with the transmission groove, so that the opening and closing gap formed between the kneading wheel and the scraping ring can change along the circumference of the rotating base. The rotating base is connected to the power drive mechanism, which drives the rotating base to rotate synchronously with the scraping ring. This causes each scraping protrusion to perform circumferential scraping on the human body during rotation. As the kneading protrusion contacts the human body to form a circumferential limit, the transmission inclined groove rotates with the rotating base. The transmission inclined groove tilts and abuts against the kneading wheel to adaptably open and close, thus achieving open and close kneading of the human body.

[0007] Compared to traditional single-function massage mechanisms, this solution integrates scraping and kneading massage methods onto the same rotating base. Through a reasonable structural design, it achieves synchronous coordination of the two massage actions, solving the problem that existing massage mechanisms are limited to a single function and cannot meet the diverse massage needs of users. At the same time, it eliminates the need for multiple independently driven massage modules on the massage device and separate drive components for the two massage functions, which helps to simplify the overall structure of the mechanism, reduce its size, and lower costs.

[0008] The scraping ring consists of multiple scraping protrusions arranged at circumferential intervals. When it rotates synchronously with the rotating base, each scraping protrusion continuously traverses the human body surface in the circumferential direction, forming a continuous and uniform circumferential scraping action, ensuring the continuity and coverage of the scraping massage. An inclined transmission groove is set on the outer periphery of the rotating base. The kneading wheel is inclinedly fitted into the transmission groove to form a rotational fit, so that the kneading wheel tilts with the transmission groove and is tilted relative to the scraping ring. This causes the opening and closing gap between the kneading wheel and the scraping ring to dynamically change along the circumference of the rotating base. When the transmission groove rotates with the rotating base, the kneading wheel is limited by the circumferential limit formed by the contact between the kneading wheel and the human body. The kneading wheel does not rotate with the rotating base. The inclined wall of the transmission groove continuously abuts against and drives the kneading wheel to adaptively open and close. There is no need to set up additional complex kneading drive structures such as eccentricity and connecting rods. The rotational power of the rotating base alone can automatically drive the kneading wheel to complete the opening and closing swing relative to the scraping ring, realizing automatic opening and closing kneading massage. The kneading action changes naturally with the rotation process. The structural design is very ingenious, the transmission logic is simple, and the operation stability is stronger.

[0009] During the massage, the circumferentially rotating scraping protrusions provide continuous circumferential scraping stimulation to the skin and fascia layer, effectively unblocking meridians and relaxing muscle tension. Simultaneously, the adaptive opening and closing kneading of the kneading rollers creates deeper compression and relaxation of local muscles. The combined effect of these two techniques makes the massage experience more comfortable and enriching, with a massage effect far superior to massage mechanisms using only one technique. Furthermore, this design allows for flexible adjustment of the number of scraping rings and kneading rollers on the outer periphery of the rotating base, based on the actual size of the massage device and usage requirements. It can accommodate small massage devices with one set of scraping rings and one set of kneading rollers, or it can use multiple sets of scraping rings and kneading rollers arranged alternately to adapt to the requirements of large massage chairs, full-body massagers, and other products, making it highly adaptable.

[0010] A further feature of the present invention includes a pair of kneading wheels. The transmission grooves are provided in two ways and are inclined towards each other. The kneading wheel bodies of the pair of kneading wheels are respectively inclined and fitted into the corresponding transmission grooves, so that the pair of kneading wheels are inclined towards each other with the transmission grooves. This causes the opening and closing gap formed between the pair of kneading wheels to change along the circumference of the rotating base. When the two transmission grooves rotate with the rotating base, the two transmission grooves can drive the pair of kneading wheels to open and close adaptively by tilting and abutting against each other, thereby realizing the opening and closing kneading of the human body.

[0011] With the further configuration described above, a pair of opposing inclined transmission grooves can drive two kneading rollers to synchronously open and close. The two kneading rollers can create symmetrical and layered alternating squeezing and kneading from both sides of the body's muscles, resulting in a stronger massage force and a wider massage coverage area than a single set of kneading rollers. Simultaneously, both kneading rollers are directly driven by the inclined walls of the transmission grooves, and the two action units share the power of the same rotating base. This eliminates the need for additional independent power or transmission structures for each individual kneading roller, further simplifying the overall movement structure, reducing manufacturing and assembly difficulties, and decreasing the probability of wear and tear and malfunctions caused by multi-component transmission during long-term operation. This extends the movement's lifespan and reduces maintenance costs. When the rotating base rotates, two opposing inclined transmission grooves synchronously abut against and drive a pair of kneading wheels to perform opposing adaptive opening and closing swings. Compared with a single kneading wheel, it can form a bilateral symmetrical kneading force, with a wider range of action and more balanced kneading force, avoiding the problem of uneven force caused by unilateral kneading, improving the comfort and coverage of kneading massage. At the same time, the symmetrical arrangement of the two kneading wheels can improve the stability of the mechanism when it rotates and reduce eccentric shaking.

[0012] A further feature of the present invention is that the scraping ring is disposed between a pair of kneading wheels, and the pair of kneading wheels and the corresponding scraping rings form an opening and closing gap that varies along the circumference of the rotating base.

[0013] By further configuring the above-mentioned design, the scraping ring is positioned between a pair of kneading rollers, creating a circumferentially varying opening and closing gap between the kneading rollers and the scraping ring on the same side. This achieves a layout where the scraping area is centered and the kneading areas are located on both sides. During rotation, the central scraping ring continuously performs circumferential scraping, while the kneading rollers on both sides simultaneously open and close in opposite directions, kneading and scraping actions work in synergy. This ensures the concentration of the scraping effect while also providing auxiliary kneading and pressing around the scraped area through the kneading on both sides. The two massage actions work together to enhance the overall massage effect. At the same time, this layout is compact, with a reasonable spatial arrangement of each component, further reducing the space occupied by the mechanism.

[0014] A further provision of the present invention: a scraping wheel is provided on the outer periphery of the rotating base. The scraping wheel has a main body and a wheel portion formed at the end of the main body. The main body is cylindrical and has the scraping protrusion on its outer periphery. The wheel portion has an inclined mounting surface on its outer periphery. A first limiting ring is provided at one end of the wheel portion near the main body, and a second limiting ring is correspondingly arranged at the other end. The corresponding end faces of the first and second limiting rings form limiting surfaces that are inclined in the same direction. The mounting surface of the wheel portion and the limiting surfaces of the first and second limiting rings at the corresponding ends together form the transmission groove. The kneading wheel is inclinedly sleeved on the mounting surface of the corresponding wheel portion and is abutted and limited by the limiting surfaces of the first and second limiting rings at the corresponding ends.

[0015] By further configuring the above-mentioned design, the inclined mounting surface of the scraping wheel, together with the inclined limiting surfaces of the first and second limiting rings at both ends, forms a regular transmission groove. On the one hand, the inclined transmission groove and corresponding limiting design allow the kneading wheel to maintain stable positioning while in an inclined mounting state, preventing it from loosening or shifting during high-speed rotation or long-term forceful massage, thus ensuring the stability of the entire mechanism from a structural perspective. On the other hand, this split-structure design integrates the scraping function into the wheel body, while the kneading function is achieved through an independent kneading wheel. The kneading wheel is directly fitted onto the mounting surface of the wheel and is abutted and limited by the limiting surface. The assembly structure is simple, requiring no additional connecting parts, which facilitates the assembly and disassembly of the mechanism.

[0016] A further provision of the present invention: a wheel portion is provided at each of the left and right ends of the wheel body, and the outer periphery of each wheel portion is provided with the mounting surface, and each end of each wheel portion is respectively provided with a first limiting ring and a second limiting ring. The mounting surface of the two wheel portions and the limiting surfaces of the first limiting ring and the second limiting ring at the corresponding ends together form two transmission inclined grooves, and a kneading wheel is respectively assembled in each transmission inclined groove.

[0017] With the above-mentioned further design, wheel sections and matching transmission grooves are respectively set at both ends of the scraping wheel body, allowing two kneading wheels to be installed simultaneously. Without increasing the length of the rotating base, the kneading area is further expanded, achieving a composite massage form of scraping in the middle and kneading at both ends simultaneously. The symmetrical arrangement of the transmission grooves at both ends and the kneading wheels ensures more even force distribution during the rotation of the rotating base, effectively reducing vibration and noise during rotation. At the same time, the symmetrical structure facilitates manufacturing, ensuring consistent action of the kneading wheels on both sides and avoiding differences in kneading force and amplitude on both sides. Furthermore, the two kneading wheels are independently positioned and installed. When a single wheel wears out and needs replacement, it is not necessary to disassemble the entire mechanism; only the corresponding kneading wheel needs to be replaced. This results in lower maintenance costs, a longer service life, and suitability for the long-term, high-frequency use needs of home massage chairs and commercial shared massage equipment.

[0018] A further embodiment of the present invention includes: the rotating base is cylindrical and includes a first base segment and a second base segment that are separately disposed; the first base segment and the second base segment are connected to each other to form an intermediate assembly part, and the inner circumference of the scraping wheel is coaxially sleeved on the intermediate assembly part; the first base segment and the second base segment are respectively provided with the second limiting ring at both ends of the corresponding intermediate assembly part; the power drive mechanism is connected to the end of the first base segment or the second base segment for transmission.

[0019] With the above-mentioned further configuration, the rotating base is cylindrical and adopts a split, independently processable first base segment and second base segment structure. The two segments are connected to form an intermediate assembly part, and the inner circumference of the scraping wheel is coaxially fitted onto this intermediate assembly part. This split design solves the problem of difficulty in assembling the scraping wheel on an integrated rotating base. During assembly, the scraping wheel can be fitted onto one base segment first, and then the other base segment can be connected. This makes it convenient to pre-fit the scraping wheel into the intermediate assembly part before splicing and fixing it. During assembly, it is not necessary to forcibly push the scraping wheel from the end of the base, which reduces the assembly difficulty and improves production assembly efficiency. In the later maintenance, worn parts can also be quickly replaced by disassembling the base segments, improving maintenance convenience. The first and second base sections each have a second limiting ring at both ends of their corresponding intermediate assembly parts. This second limiting ring, together with the first limiting ring on the scraping wheel, provides symmetrical support to both ends of the kneading wheel, further enhancing the limiting effect on the kneading wheel. This effectively prevents the kneading wheel from shifting when the rotating base rotates at high speed, ensuring the stability of the kneading wheel's movement and thus ensuring the regularity of the kneading action. The power drive mechanism is directly connected to the end of either the first or second base section, resulting in a more direct transmission path and reducing power loss during transmission. This ensures that the rotating base, scraping wheel, and kneading wheel receive sufficient and stable driving force, keeping the scraping force and kneading pressure stable and guaranteeing the massage effect.

[0020] A further provision of the present invention includes: a first reduction gearbox and a second reduction gearbox are respectively configured at both ends of the rotating base, the rotating base is rotatably mounted between the first reduction gearbox and the second reduction gearbox, and the power drive mechanism is located in the first reduction gearbox, which includes a motor and a worm gear transmission assembly, the motor being connected to one end of the rotating base via the worm gear transmission assembly.

[0021] With the above-mentioned further configuration, a first reduction gearbox and a second reduction gearbox are respectively installed at both ends of the rotating base. The rotating base is rotatably mounted between the two reduction gearboxes, achieving double-end support for the rotating base. This significantly improves the rigidity and stability of the rotating base during rotation, effectively preventing swaying or tilting when the rotating base rotates or is subjected to human body reaction forces. The power drive mechanism is located in the first reduction gearbox, including a motor and a worm gear transmission assembly. The motor is connected to one end of the rotating base through the worm gear transmission assembly. Integrating the power drive mechanism into the reduction gearbox makes the transmission structure of the mechanism more compact. At the same time, the reduction gearbox provides a closed protective space for the motor and the worm gear transmission assembly, effectively preventing external dust and debris from entering, reducing component wear, and extending the service life of the power mechanism. The worm gear transmission assembly has the characteristics of speed reduction and torque amplification, which can convert the high-speed, low-torque output of the motor into the low-speed, high-torque output required by the rotating base, ensuring that the scraping and kneading actions have sufficient force.

[0022] A further embodiment of the present invention includes: the worm gear transmission assembly comprising a primary worm and a primary worm wheel meshing with each other, and a secondary worm and a secondary worm wheel meshing with each other; the primary worm is arranged axially along the rotating base and coaxially connected to the output shaft of the motor; the secondary worm is arranged perpendicular to the axial direction of the rotating base and coaxially connected to the primary worm wheel; the secondary worm wheel is coaxially connected to a drive gear; output gears are provided at the center positions of both ends of the rotating base; the drive gear meshes with one of the output gears to drive the rotating base to rotate.

[0023] By employing the aforementioned further design, a two-stage worm gear transmission combined with gear meshing achieves multi-stage reduction and torque amplification. This provides the rotating base with more ample and stable driving torque, ensuring stronger and more stable scraping force from the scraping protrusions and kneading force from the kneading wheels, thus enhancing the massage effect. The axial and vertical spatial arrangement of the first and second-stage worm gears optimizes the internal space utilization of the mechanism, making the overall transmission structure more compact and effectively reducing the size of the mechanism. The meshing transmission method of the drive gear and output gear ensures smooth power transmission and uniform rotation speed, making the rotating base rotate more smoothly. This, in turn, allows for continuous and uninterrupted scraping and kneading actions, improving the user's massage comfort. Output gears are located at both ends of the rotating base, allowing for flexible selection of the power drive end according to different usage scenarios and assembly requirements, significantly improving the assembly adaptability of the mechanism.

[0024] A further provision of the present invention: the first gearbox includes a detachably connected gearbox bottom cover, a gearbox middle seat, and a gearbox end cover; The gearbox is provided with a support plate, which forms a first chamber between the support plate and the bottom cover of the gearbox, and a second chamber between the support plate and the end cover of the gearbox. The motor is fixedly mounted on the end cover of the gearbox. The worm gear transmission assembly is located in the second chamber. The drive gear and output gear are located in the first chamber. The first transmission shaft and the second transmission shaft are rotatably mounted on the support plate. The first-stage worm gear and the second-stage worm are located on the first transmission shaft. The second-stage worm gear and the drive gear are located on the second transmission shaft. The support plate has a support shaft at its center. The end of the rotating base is rotatably mounted on the support shaft.

[0025] With the above-mentioned further design, the first gearbox adopts a three-section structure consisting of a detachable bottom cover, a middle seat, and an end cover, facilitating the assembly and maintenance of internal transmission components such as the motor, worm gear drive assembly, and gears. The middle seat is equipped with a support plate, forming a first chamber between the support plate and the bottom cover, and a second chamber between the support plate and the end cover. The worm gear drive assembly is located in the second chamber, while the drive gear and output gear are located in the first chamber. This achieves a separate arrangement of the worm gear drive and gear drive, effectively avoiding motion interference between different transmission components and improving the stability of the transmission structure. The first and second drive shafts are rotatably mounted on the support plate. The first-stage worm gear and the second-stage worm are located on the first drive shaft, and the second-stage worm gear and the drive gear are located on the second drive shaft. This makes the installation of each transmission component more regular, and the same support plate provides stable support for the two drive shafts. A support shaft is located at the center of the support plate, and the end of the rotating base is rotatably mounted on the support shaft, forming a precise coaxial rotation support for the end of the rotating base. This further improves the smoothness of the rotating base's operation and makes the transmission and massage actions of the entire movement more reliable. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-9 As shown, the present invention provides a scraping and kneading massage mechanism, comprising a rotating base 1, and at least one scraping ring 2 and at least one kneading wheel 3 disposed on the outer periphery of the rotating base 1; The scraping ring 2 is composed of a plurality of scraping protrusions 21 arranged circumferentially around the outer periphery of the rotating base 1, and rotates synchronously with the rotating base 1. The kneading wheel 3 includes a kneading wheel body 31, and a plurality of kneading protrusions 32 are provided on the outer periphery of the kneading wheel body 31 along its circumferential direction. Each kneading protrusion is a hemispherical protrusion structure and is integrally formed on the outer periphery of the kneading wheel body. The rotating base 1 has a transmission groove 10 that rotates synchronously with it on its outer periphery. The transmission groove 10 is inclined, and the kneading wheel 31 is inclinedly fitted inside the transmission groove 10 to form a rotational fit. The kneading wheel 3 is inclined relative to the scraping ring 2 along the transmission groove 10, which allows the opening and closing gap between the kneading wheel 3 and the scraping ring 2 to change along the circumference of the rotating base 1. After inclination, the distance between the two gradually changes in size along the circumference, that is, along the circumference of the rotating base, the distance changes from small to large and then from large to small in a cycle. The tilt angle of the kneading wheel can be adjusted as needed to adapt to the massage needs of different parts. For large areas such as the shoulders and neck, waist and back, and legs, the angle can be adjusted to a larger or smaller angle to adapt to different kneading intensity requirements.

[0030] The rotating base 1 is connected to the power drive mechanism 4. The power drive mechanism 4 drives the rotating base 1 to rotate synchronously with the scraping ring 2, so that each scraping protrusion 21 forms a circumferential scraping motion on the human body during the rotation. Since the kneading protrusion 32 forms a circumferential limit when it contacts the human body, when the transmission groove 10 rotates with the rotating base 1, the transmission groove 10 drives the kneading wheel 3 to open and close adaptively by tilting and abutting against it, thereby realizing the opening and closing kneading of the human body.

[0031] Specifically, it includes a pair of kneading wheels 3. The transmission groove 10 has two sections and is inclined towards each other. The kneading wheel bodies 31 of the pair of kneading wheels 3 are respectively inclined and sleeved in the corresponding transmission groove 10, so that the pair of kneading wheels 3 are inclined towards each other with the transmission groove 10. This causes the opening and closing gap formed between the pair of kneading wheels 3 to change along the circumference of the rotating base 1. When the two transmission grooves 10 rotate with the rotating base 1, the two transmission grooves 10 can drive the pair of kneading wheels 3 to open and close adaptively by tilting and abutting against each other, so as to realize the opening and closing kneading of the human body.

[0032] Specifically, the scraping ring 2 is positioned between a pair of kneading rollers 3, and multiple scraping rings 2 are arranged along the axial direction of the rotating base, such as two or three. The pair of kneading rollers 3 and the corresponding scraping rings 2 form an opening and closing gap that varies circumferentially along the rotating base 1. Of course, the scraping rings can also be positioned on either side of the pair of kneading rollers, not limited to the middle, and their positions can be flexibly adjusted according to the installation requirements of different parts of the massage chair. When the rotating base rotates, the pair of opposing kneading rollers rotate synchronously, and the opening and closing gap continuously changes cyclically. When the kneading rollers rotate to a position close to the human body, the two kneading rollers gradually close, cooperating with the scraping rings to create a pinching and squeezing action on the human muscles. When the kneading rollers rotate away from the human body, the two kneading rollers gradually open, and the muscles relax accordingly.

[0033] Specifically, a scraping wheel 22 is fixed or integrally provided on the outer periphery of the rotating base 1. The scraping wheel 22 has a wheel body 221 and a wheel portion 222 integrally formed at the end of the wheel body 221. The wheel body 221 is cylindrical and has scraping protrusions 21 on its outer periphery. Each scraping protrusion is an arc-shaped protrusion structure and is integrally formed on the outer periphery of the scraping wheel body. The wheel portion 222 has an inclined mounting surface 224 on its outer periphery, and a first limiting ring 225 is integrally provided on the end of the wheel portion near the wheel body 221. The other end is correspondingly equipped with a second limiting ring 14, and the corresponding end faces of the first limiting ring 225 and the second limiting ring 14 form a limiting surface 226 inclined in the same direction. The mounting surface 224 of the wheel part 222 and the limiting surfaces 226 of the first limiting ring 225 and the second limiting ring 14 at the corresponding ends together form the transmission groove 10. The kneading wheel body 31 is inclinedly sleeved on the mounting surface 224 of the corresponding wheel part 222, and is abutted and limited by the limiting surfaces 226 of the first limiting ring 225 and the second limiting ring 14 at the corresponding ends. Of course, the scraping protrusion can also be integrally formed on the outer periphery of the rotating base. Specifically, a wheel portion 222 is provided at each of the left and right ends of the wheel body 221. Each wheel portion 222 has a mounting surface 224 on its outer periphery. Each wheel portion 222 has a first limiting ring 225 and a second limiting ring 14 at its two ends. The mounting surfaces 224 of the two wheel portions 222 and the limiting surfaces 226 of the first limiting ring 225 and the second limiting ring 14 at their corresponding ends together form two transmission inclined grooves 10. A kneading wheel 3 is respectively installed in each transmission inclined groove 10. Specifically, the rotating base 1 is cylindrical and includes a first base segment 11 and a second base segment 12 that are separately arranged. After the first base segment 11 and the second base segment 12 are joined together, an intermediate assembly part 13 for mounting the scraping wheel is formed at the connection position between the two. The scraping wheel body 22 is coaxially sleeved on the intermediate assembly part 13 and connected and fixed. The first base segment 11 and the second base segment 12 are respectively provided with the second limiting ring 14 at both ends of the corresponding intermediate assembly part 13. Of course, the second limiting ring is detachably connected to the wheel. A pair of second limiting rings are inclined towards each other, and a pair of first limiting rings are inclined towards each other. The first limiting ring and the second limiting ring are designed to be inclined, thereby forming an inclined limiting surface. The power drive mechanism 4 is connected to the end of the first base segment 11 or the second base segment 12.

[0034] Specifically, a first reduction gearbox 6 and a second reduction gearbox 7 are respectively configured at both ends of the rotating base 1. The rotating base 1 is rotatably mounted between the first reduction gearbox 6 and the second reduction gearbox 7. The power drive mechanism 4 is located in the first reduction gearbox 6, which includes a motor 41 and a worm gear transmission assembly 42. The motor 41 is connected to one end of the rotating base 1 through the worm gear transmission assembly 42, or the motor can directly drive the rotating base. The worm gear transmission assembly 42 includes a first-stage worm 421 and a first-stage worm wheel 422 meshing with each other, and a second-stage worm 423 and a second-stage worm wheel 424 meshing with each other. The worm gears can be in multiple sets or a single set. The first-stage worm 421 is arranged axially along the rotating base 1 and coaxially connected to the output shaft of the motor 41. The second-stage worm 423 is arranged perpendicular to the axial direction of the rotating base 1 and coaxially connected to the first-stage worm gear 422. The second-stage worm gear 424 is coaxially connected to a drive gear 43. Output gears 15 are provided at the center of both ends of the rotating base 1. Specifically, an output gear 15 is integrally provided at the end of the first base segment 11 or the second base segment 12. The drive gear 43 meshes with one of the output gears 15 to drive the rotating base 1 to rotate. The drive gear and the output gear are spur gears.

[0035] Specifically, the first gearbox 6 includes a detachably connected gearbox bottom cover 61, a gearbox middle seat 62, and a gearbox end cover 63, which are detachably connected by bolts or clips; the gearbox middle seat 62 is integrally provided with a support plate 621, which forms a first chamber 64 between the support plate 621 and the gearbox bottom cover 61, and a second chamber 65 between the support plate 621 and the gearbox end cover 63; the motor 41 is a servo motor 41, which is fixedly installed on the gearbox end cover 63 of the first gearbox 6 by bolts, and the motor output shaft is coaxially connected and fixed to the first-stage worm gear 421, which extends through the gearbox end cover 63 into the interior of the first gearbox 6. The worm gear transmission assembly 42 is located in the second chamber 65, and the drive gear 43 and the output gear 15 are located in the first chamber 64. The first transmission shaft 622 and the second transmission shaft 623 are rotatably mounted on the support plate 621 via bearings. The first-stage worm gear 422 and the second-stage worm gear 423 can be integrally mounted on the first transmission shaft 622 or circumferentially positioned by a sleeve connection. The second-stage worm gear 424 and the drive gear 43 are integrally mounted on the second transmission shaft 623 or circumferentially positioned by a sleeve connection. The support plate 621 has an integrally mounted support shaft 6211 at its center, and the end of the rotating base 1 is rotatably mounted on the support shaft 6211.

[0036] The first base segment 11 and the second base segment 12 can be detachably connected by bolts or clips; or the end of the first base segment 11 can be rotatably mounted on the first gearbox and the second base segment 12 can be rotatably mounted on the second gearbox, thereby achieving docking and fixing of the first base segment 11 and the second base segment 12.

[0037] The scraping and kneading massage mechanism of the present invention provides power through a power drive mechanism to drive the rotating base to rotate, simultaneously realizing a composite massage action of circumferential scraping and adaptive opening and closing kneading. The specific working process is as follows: The power drive mechanism is located inside the first reduction gearbox. After the motor starts, it is driven by a worm gear transmission assembly. The first-stage worm rotates with the motor output shaft, driving the meshing first-stage worm wheel to rotate, which in turn drives the coaxial second-stage worm to rotate. The second-stage worm then drives the meshing second-stage worm wheel to rotate, which in turn drives the coaxial drive gear to rotate. The drive gear meshes with the output gear at the end of the rotating base, thereby driving the rotating base to rotate continuously. The two ends of the rotating base are supported by the support shaft of the first reduction gearbox and the second reduction gearbox, respectively, to ensure smooth operation.

[0038] When the rotating base rotates, it drives the outer circumferential scraping ring to rotate synchronously. The scraping ring is composed of multiple scraping protrusions arranged at circumferential intervals. Each scraping protrusion rotates circumferentially with the rotating base, continuously tracing across the human body surface, forming a continuous and uniform circumferential scraping massage. Simultaneously, the transmission groove on the outer periphery of the rotating base rotates synchronously with the rotating base. The kneading wheel body is inclinedly fitted into the transmission groove and forms a rotational fit. The kneading protrusion on the outer periphery of the kneading wheel contacts the human body, forming a circumferential contact limit, so that the kneading wheel maintains circumferential positioning relative to the human body. The transmission groove is inclined towards the scraping ring side. As the rotating base drives the transmission groove to rotate, the inclined wall of the transmission groove continuously abuts against the kneading wheel body, driving the kneading wheel to make adaptive opening and closing swings, thereby realizing an opening and closing kneading massage that conforms to the contours of the human body.

[0039] When a pair of kneading wheels are set, the two transmission inclined grooves are arranged at opposite angles, driving the pair of kneading wheels to swing open and close synchronously. The gap between the two kneading wheels and the gap between the kneading wheels and the scraping ring change dynamically with the rotation process, realizing symmetrical and balanced kneading on both sides. The scraping ring is set between the pair of kneading wheels, forming a synergistic massage effect of scraping in the middle and kneading on both sides simultaneously.

[0040] The mounting surface of the scraping wheel body and the limiting surfaces of the first and second limiting rings form a regular transmission groove, which limits the kneading wheel body axially and radially, preventing the kneading wheel from moving or deviating during operation, and ensuring precise and smooth opening and closing swinging movements. The rotating base adopts a split structure with the first base section and the second base section docking, which facilitates the coaxial mounting of the scraping wheel body in the middle assembly part, ensuring the concentricity of the overall assembly and ensuring the long-term stable operation of the mechanism.
