Description

Technical Field

[0001] This invention relates to the field of massage machine technology, specifically to a guiding device for a rhythmic massage machine and the rhythmic massage machine itself. Background Technology

[0002] With the fast pace of modern life and increasing health awareness, rhythmic massage machines, as a physical therapy device that effectively promotes blood circulation, relieves muscle fatigue, and improves bodily functions, are gradually gaining popularity among consumers. The core technology of a rhythmic massage machine lies in the alternating reciprocating motion generated vertically by the rhythmic frame, which drives the support frame carrying the user to move vertically, thus simulating the effect of passive movement. In this process, the guide device, as a key mechanical structure connecting the rhythmic frame and the support frame, directly determines the overall massage experience and lifespan of the machine through its stability, smoothness, and durability.

[0003] In existing rhythmic massager technology, to achieve posture changes of the support frame (such as backrest tilting, leg raising, and overall sliding), the industry typically employs a sliding mechanism that combines guide rails and guide components. Currently, most mainstream guide devices on the market use ordinary channel steel structures as guide rails, with guide components (such as sliders or rollers) embedded in the grooves of the channel steel for limiting and guiding. However, this traditional channel steel structure has revealed many insurmountable defects in practical applications, severely restricting the improvement of rhythmic massager performance.

[0004] First, from the perspective of material mechanics, ordinary channel steel guide rails have relatively weak bending stiffness and torsional resistance. During the operation of a rhythmic massager, the guide rail not only needs to withstand the static weight of the support frame and the user, but also needs to withstand the periodic alternating impact loads generated by the rhythm over a long period. Under repeated stress, the channel steel guide rail is prone to elastic deformation or even plastic bending, resulting in a decrease in the straightness of the guide rail and an increase in the guide clearance. Once the guide rail deforms, the guide components will experience jamming, abnormal noise, or shaking during sliding, which not only reduces the smoothness of posture adjustment, but also accelerates the wear of the guide components, significantly shortening the maintenance cycle and service life of the equipment.

[0005] Secondly, to further enhance product comfort and functionality, the industry has begun exploring the addition of foot massagers (leg supports) to the front of rhythmic massagers. While this improvement satisfies users' needs for full-body massage, it also brings new technical challenges. The addition of foot massagers significantly shifts the overall center of gravity of the support frame forward. Under the excitation of vertical rhythm, the coupled system formed by the support frame and leg supports is more likely to approach or enter the resonant frequency. Resonance amplifies the vibration amplitude of the structure, placing higher demands on the structural strength of the guide rail. Traditional channel steel structures are more prone to deformation under these conditions, and this deformation further exacerbates the resonance effect, creating a vicious cycle that ultimately leads to a sharp decline in the stability of the equipment and may even cause safety hazards.

[0006] To address the aforementioned problems, existing technological improvements often limit themselves to material replacement or localized reinforcement, such as using thicker steel or adding localized stiffeners. While these methods can improve structural strength to some extent, they fail to fundamentally solve the stress deficiencies of channel steel structures under complex working conditions and lead to a significant increase in the overall weight and cost of the equipment. More importantly, these improvements fail to systematically consider how to suppress resonance and vibration by optimizing the fit between the guide rails and guide components, thereby improving the overall performance and reliability of the equipment.

[0007] Therefore, designing a new type of guiding device with high structural strength, strong resistance to deformation, effective suppression of resonance and vibration, and stable sliding of the support frame has become a core problem that urgently needs to be solved in the field of rhythmic massage machine technology. Summary of the Invention

[0008] The purpose of this invention is to provide a guiding device for a rhythmic massager and a rhythmic massager in order to solve the problems of insufficient structural strength and easy deformation of the channel steel structure guide rail in the prior art.

[0009] To achieve the above objectives, in a first aspect, the present invention provides a guiding device for a rhythmic massager, suitable for guiding the support frame of the rhythmic massager to slide on its rhythmic frame to change the user's sitting or lying posture. The guiding device includes at least one guide member and a track member for defining the movement trajectory of the guide member. The track member includes a first guide rail and a second guide rail arranged at intervals, defining a guide channel between the first guide rail and the second guide rail. The guide member is slidably embedded in the guide channel. The guiding device further includes at least one locking member connected between the first guide rail and the second guide rail and applying a locking force to them to bring them closer together, so that the guide surfaces of the first guide rail and the second guide rail respectively apply continuous lateral constraints to the guide member from opposite sides. The lateral constraints generate a pressing force and a frictional force between the guide member and the guide surface to suppress the support frame from jumping displacement relative to the rhythmic frame when the rhythmic massager is rhythmically moving.

[0010] Furthermore, the track component includes: a first extension for guiding the carrier frame to move back and forth; and The second extension section is used to guide the support frame to tilt up and down; wherein the guide includes a first guide that cooperates with the first extension section and a second guide that is adapted to the second extension section.

[0011] Furthermore, the first extension segment is horizontally positioned, the second extension segment is inclined upwards, the first extension segment and the second extension segment are smoothly connected by an arc-shaped extension segment, the first guide is configured to move only on the first extension segment, and the second guide is configured to move on both the second extension segment and the arc-shaped extension segment.

[0012] Furthermore, the first guide member is configured as a sliding guide member, which slides in conjunction with the first extension section; the second guide member is configured as a rolling guide member, which rolls in conjunction with the second extension section.

[0013] Furthermore, the first guide member is configured as a slider having a pair of sliding guide surfaces arranged parallel to each other in the vertical direction; the second guide member is configured as a roller.

[0014] Furthermore, the locking member is configured in three parts, one of which is disposed between the first extension section and the second extension section, and the other two are disposed at the outer ends of the first extension section and the second extension section, respectively.

[0015] Furthermore, the first guide member and the second guide member are configured to move within the guide space formed between two adjacent locking members, respectively.

[0016] Furthermore, the upper side of the first guide rail has at least one reinforcing rib, which is configured to extend in a first extension section and a second extension section to increase the bending strength of the first guide rail.

[0017] Furthermore, the locking member includes: a first end face fixedly connected to a first guide rail; and a second end face fixedly connected to a second guide rail; wherein the first end face and the second end face are fixedly connected by at least two spaced support ribs, the support ribs being perpendicular to the first end face and the second end face.

[0018] Furthermore, the locking member is configured in a square shape.

[0019] Furthermore, the first guide rail has an upper wear-resistant member that presses against the upper side of the guide member, and the second guide rail has a lower wear-resistant member that presses against the lower side of the guide member.

[0020] Furthermore, viewed in the width direction of the support frame, the track members are configured as a pair arranged at intervals; the outer side of the guide member has a locking piece that slides with the side wall of the track member, the locking pieces being arranged in pairs in the width direction to limit the swaying displacement of the support frame in its width direction.

[0021] In a second aspect, the present invention provides a rhythmic massage machine, which includes a support frame, a rhythmic frame, and a leg rest, wherein the rhythmic frame is driven to output rhythmic massage movements; the support frame is attached to the rhythmic frame via a guide device, the guide device being configured as a guide device for the rhythmic massage machine as described in any of the above claims.

[0022] Furthermore, the support frame includes a back frame and a seat frame, which are pivotally connected, and the leg frame and the seat frame are pivotally connected; the rhythm frame also has a third guide rail for guiding the back frame to change its tilt angle, and the back frame has a third guide member adapted to the third guide rail.

[0023] The beneficial effects of this invention are as follows: First, by setting a locking component connected between the first and second guide rails, this invention applies a continuous, opposing locking force to the two guide rails, ensuring the locking effect of the two guide rails throughout the entire process and effectively improving the bending and torsional resistance of the overall cross-section of the guide rails. Addressing the harsh working conditions of the rhythmic massage machine under long-term high-frequency alternating impact loads and the self-weight compression of the support frame, this structure can effectively resist reciprocating impact loads, preventing problems such as bending, warping, and deformation of the guide rails. It solves the defects of traditional channel steel guide rails, such as insufficient strength, short service life, and severe accuracy degradation over long-term use, significantly improving the structural stability and durability of the guiding device.

[0024] Secondly, the locking component applies continuous lateral constraint to the guide surfaces of the first and second guide rails from opposite sides of the guide member, maintaining a tight contact and generating friction between the guide member and the guide surface. During rhythmic operation, the rhythmic massager effectively counteracts the vibration displacement caused by the rhythmic impact, suppresses the jumping displacement of the support frame relative to the rhythmic frame, and significantly improves the user experience and safety.

[0025] Third, by setting an arc-shaped extension section to smoothly connect the first and second extension sections, the support frame moves smoothly during posture changes without hard impact, thus improving massage comfort.

[0026] Fourth, by setting reinforcing ribs on the upper side of the first guide rail and extending along the first and second extension sections, the bending strength of the first guide rail is significantly increased, preventing it from bending and deforming under alternating loads during the pulsation process.

[0027] Fifth, by setting upper and lower wear-resistant parts on the inner sides of the first and second guide rails respectively, which press against the upper and lower sides of the guide components, the guide rails are effectively protected from wear, extending the service life of the equipment. Moreover, the wear-resistant parts can be replaced individually, reducing maintenance costs.

[0028] Sixth, by setting a locking piece on the outside of the guide piece that slides in cooperation with the side wall of the track component, and by arranging the locking pieces in pairs in the width direction, the degree of freedom of the support frame in the width direction is effectively restricted, preventing it from swaying or shifting left and right, and further improving the guiding stability.

[0035] Please see Figures 1-12 This embodiment provides a guide device for a rhythmic massager, which is used in the rhythmic massager to guide the support frame 100 to slide smoothly relative to the rhythmic frame 200, so as to realize the user's posture change from sitting to lying down.

[0036] Please refer to section 1 for details. The guiding device 300 includes a guide member 310 and a track member 320. The track member 320 is used to define the movement trajectory of the guide member 310. The track member 320 includes a first guide rail 321 and a second guide rail 322. The first guide rail 321 is located above and the second guide rail 322 is located below. The two are arranged at intervals in the vertical direction and define a guiding channel 323. The guide member 310 is slidably embedded in the guiding channel 323, so that the guide member 310 can slide back and forth along the extension direction of the track member 320.

[0037] Please refer to 1 and 2 for details. The guide device 300 also includes a locking member 330, which is connected between the first guide rail 321 and the second guide rail 322 and applies a locking force to them to bring them closer together. This locking force causes the lower guide surface of the first guide rail 321 and the upper guide surface of the second guide rail 322 to apply continuous lateral constraints to the guide member 310 from opposite sides (upper and lower sides), respectively. This lateral constraint generates significant clamping and frictional forces between the guide member 310 and the guide surface. When the rhythm frame 200 drives the track member 320 to rhythmically move, it can effectively suppress the jumping displacement of the support frame 100 relative to the rhythm frame 200, ensuring the stability of the rhythm transmission.

[0038] Please refer to section 3 for details. In practical applications, the support frame 100 not only needs to move forward and backward but also needs to tilt significantly. Therefore, the track component 320 is divided into different functional sections along its extension path, including a first extension section 324, a second extension section 325, and an arc-shaped extension section 326. The first extension section 324 is horizontally positioned to guide the support frame 100 in linear forward and backward movement; the second extension section 325 is tilted upward to guide the support frame 100 to rise during tilting; the arc-shaped extension section 326 connects the first extension section 324 and the second extension section 325, forming a smooth arc shape. The transition from the first extension section 324 to the second extension section 325 is smooth and without any hard impact.

[0039] Please refer to 5 for details. Accordingly, the guide 310 includes two types that cooperate with different extensions, including the first guide 311 and the second guide 312. The first guide member 311 is configured as a sliding guide member, such as a slider, which cooperates with the first extension section 324. The first guide member 311 has a pair of sliding guide surfaces arranged parallel in the vertical direction, which respectively fit against the inner surfaces of the first guide rail 321 and the second guide rail 322. Since the first extension section 324 mainly bears the vertical force, the sliding cooperation can provide a larger support area and friction. The slider and the first extension section 324 have surface contact, with a large contact area and high friction, making the first guide member 311 more stable when sliding within the track component 320. The second guide member 312 is configured as a rolling guide member, such as a roller, which cooperates with the second extension section 325. Since the second extension section 325 involves the change of the bearing frame 100° angle, the roller cooperation can effectively reduce frictional resistance. The roller and the second extension section 325 have line contact, with a small contact area and low friction, making the second guide member 312 slide more smoothly within the track component 320.

[0040] Please refer to 5 for details. The first guide member 311 has at least a plurality of grooves 3111 arranged along the width direction of the slider on the sliding guide surface. The grooves 3111 make the slider uneven, reduce the actual contact area and reduce viscous wear.

[0041] Please refer to 5 for details. The first guide member 311 has a spline hole 3112, and the pin 313 connected to it is a spline shaft. Multiple teeth of the spline shaft mesh with the tooth grooves of the spline hole 3112 at the same time. The torque is shared by multiple pairs of teeth, which can withstand a larger torque and prevent the first guide member 311 from rotating or slipping during sliding.

[0042] Please refer to 5 for details. The second guide member 312 has a shaft hole 3121, and the pin 313 connected to it is a common pin 313, so that the second guide member 312 can rotate around the pin 313, thereby forming rolling friction and reducing frictional resistance.

[0043] In this embodiment, both the slider and the roller are made of POM (polyoxymethylene) material.

[0044] Please refer to 1 and 2 for details. To further enhance structural strength, a reinforcing rib 340 is provided on the upper outer wall of the first guide rail 321. This reinforcing rib 340 extends along the length of the first extension 324 and the second extension 325, significantly increasing the bending strength of the first guide rail 321 and preventing it from sagging over long spans.

[0045] In this embodiment, the first extension segment 324, the second extension segment 325 and the arc-shaped extension segment 326 are integrated into one piece, resulting in higher overall bending and torsional stiffness and better resistance to deformation caused by long-term high-frequency alternating loads of the rhythmic massager.

[0046] In other feasible embodiments, the first extension segment 324, the second extension segment 325, and the arc-shaped extension segment 326 are set separately. The first extension segment 324, the second extension segment 325, and the arc-shaped extension segment 326 can be processed separately with the most suitable cross-sectional shape and length, without the need for a large-length bending mold or special rolling equipment, thus reducing the initial tooling investment.

[0047] Please refer to section 4 for details. In this embodiment, the locking member 330 is constructed in a U-shape. Specifically, the locking member 330 includes a first end face 331, a second end face 332, and supporting ribs 333. The first end face 331 is fixedly connected to the inner surface of the first guide rail 321 by bolts (the first end face 331 and the first guide rail 321 have through holes for mounting bolts at corresponding positions). The second end face 332 is connected to the inner surface of the second guide rail 322 by bolts (the second end face 332 and the second guide rail 322 have through holes for mounting bolts at corresponding positions). Two supporting ribs 333 are arranged at intervals and vertically connected between the first end face 331 and the second end face 332. The U-shaped locking member 330 tightens and fixes the upper and lower guide rails, forming a stable structure similar to a box beam. This greatly improves the overall bending modulus and torsional stiffness of the track member 320, effectively preventing bending and torsional deformation of the guide rails under long-term load.

[0048] In some other feasible embodiments, the support ribs 333 are configured as three, four or five, arranged at intervals and vertically connected between the first end face 331 and the second end face 332.

[0049] In this embodiment, the first end face 331, the second end face 332, and the support rib 333 of the locking component 330 are cast in one piece, with no splicing gaps between the parts, no bolt hole weakening or weld defects, uniform stress distribution, stronger impact resistance and fatigue resistance, and less prone to breakage or deformation, for example, by cutting or die casting.

[0050] In some other feasible embodiments, the first end face 331, the second end face 332, and the support rib 333 of the locking member 330 are fixedly connected by bolts or welding, and each part can be processed separately, reducing the mold complexity or processing difficulty when integral molding.

[0051] Please refer to 2 and 3 for details. The locking member 330 is configured as three locking members 330. The first locking member 330 is disposed in the transition area between the first extension 324 and the second extension 325 (i.e., at the connection between the first extension 324 and the arc-shaped extension 326); the second locking member 330 is disposed at the outer end (rear end) of the first extension 324; and the third locking member 330 is disposed at the outer end (front end) of the second extension 325.

[0052] Furthermore, a guide space is formed between two adjacent locking members 330, that is, the two adjacent locking members 330 divide the guide channel 323 into two guide spaces, so that the first guide member 311 and the second guide member 312 can move in their respective guide spaces. The arrangement of the three locking members 330 can not only keep the first guide rail 321 and the second guide rail 322 locked throughout the entire process, preventing the guide rails from opening or deforming under long-term rhythmic impact, but also use the locking members 330 to limit the stroke of the guide member 310, avoiding overtravel, derailment, and jamming of the guide member, thus greatly improving the safety and regularity of the guiding movement.

[0053] To prevent wear and improve wear resistance, the inner side of the first guide rail 321 has an upper wear-resistant part 350, which abuts against the upper side of the guide member 310; the inner side of the second guide rail 322 has a lower wear-resistant part 360, which abuts against the lower side of the guide member 310. During the reciprocating sliding process of the guide member 310, wear only occurs on the surface of the wear-resistant part, which can effectively protect the guide rail from wear and avoid problems such as guide rail precision failure, loose fit, and increased runout caused by long-term friction; at the same time, the wear-resistant part can be replaced individually without replacing the entire guide rail, which greatly reduces equipment maintenance costs.

[0054] In this embodiment, the upper wear-resistant part 350 and the lower wear-resistant part 360 can be made of polymer materials (such as POM, nylon) to reduce noise and extend the life of the guide rail.

[0055] In this embodiment, the upper wear-resistant part 350 and the lower wear-resistant part 360 are fixed to the first guide rail 321 and the second guide rail 322 by bolts (the upper wear-resistant part 350, the lower wear-resistant part 360 and the first guide rail 321 and the second guide rail 322 are provided with through holes for mounting bolts at corresponding positions).

[0056] Please refer to 10 and 11 for details. Observing along the width of the support frame 100, the track members 320 are arranged in pairs at intervals (i.e., one set on each side). Correspondingly, the guide members 310 are arranged in pairs at intervals (i.e., one set on each side) to fit the track members 320. The outer side of the guide member 310 has a locking piece 370 that slides against the side wall of the track member 320. The locking piece 370 is fixed to the pin 313 by bolts and can slide against either the left or right side wall of the track member 320. The locking pieces 370 are arranged in pairs along the width, fitting against both sides of the track member 320, thereby restricting the freedom of the support frame 100 in the left and right directions and preventing it from swaying or shifting.

[0057] Please refer to 11 for details. The surface of the locking piece 370 that contacts the track component 320 is constructed as a wear-resistant surface 371. The wear-resistant surface 371 is formed by embedding a polytetrafluoroethylene (PTFE) gasket, which has an extremely low coefficient of friction (dry coefficient of friction is about 0.04 to 0.1) and excellent wear resistance, which can reduce the wear of the locking piece 370 and the track component 320 while ensuring low friction sliding.

[0058] The rhythmic massager of this embodiment uses the aforementioned guiding device for rhythmic massagers. A vibration drive device is installed at the center of the bottom of the rhythmic massager. The vibration drive device includes a three-phase asynchronous motor with a rated power of 750W and an eccentric cam or eccentric shaft. In this embodiment, it is an eccentric shaft. The output shaft of the motor is connected to the rotating shaft of the eccentric shaft through a coupling. When the motor operates at a set speed (the speed can be adjusted within the range of 300rpm to 3000rpm, corresponding to an excitation frequency of 5Hz to 50Hz), the eccentric shaft generates centrifugal force. The vertical component of this centrifugal force drives the rhythmic frame 100 to produce periodic reciprocating motion in the vertical direction, i.e., vertical rhythm.

[0059] Please refer to sections 6 and 7 for details. The support frame 100 includes a backrest 110, a seat frame 120, and a leg rest 130. The backrest 110 supports the user's back; the seat frame 120 supports the user's buttocks; and the leg rest 130 supports the user's legs or provides massage to the lower limbs (i.e., a lower limb massager). The backrest 110 and seat frame 120 are pivotally connected by a connecting shaft (this connecting shaft is a pin 313 for mounting the first guide member), and the leg rest 130 and seat frame 120 are pivotally connected by a connecting shaft. When the seat frame 120 moves forward via the guide device 300, the backrest 110 and seat frame 120 automatically unfold under the action of the connecting shaft, forming a reclining position. Pivoting connection is a common movable connection structure in the mechanical field, capable of connecting two workpieces, with one workpiece able to rotate relative to the other. The axis of rotation is typically the axis of the pin. Pivoting connection is a conventional technique in the mechanical field and will not be elaborated further in this embodiment.

[0060] Please refer to 8 and 9 for details. The first guide member 311 is connected to the back frame 110 via a pin 313, and the second guide member 312 is connected to the seat frame 120 via a pin 313. The track component 320 is fixedly connected to the rhythm frame 200 by welding or bolts. The posture adjustment of the support frame 100 is achieved by the sliding of the first guide member 311 and the second guide member 312 relative to the track component 320.

[0061] Please refer to section 7 for details. To ensure smooth operation of the back frame 110, the rhythm frame 200 is also equipped with a third guide rail 210 for guiding the back frame 110 to change its tilt angle. The third guide rail 210 is a common channel steel guide rail, usually installed on the rhythm frame 200 and located below the second guide rail 322, and has a certain tilt curvature. The back frame 110 has a third guide member 121 that is adapted to the third guide rail 210.

[0062] Please refer to 8 for details. The third guide 121 (usually a roller) is mounted on the lower end of the back frame 110 via a pin and can slide within the third guide rail 210.

[0063] Please refer to 12 for details. A drive can be provided at the bottom of the rhythm massager. The drive can be a linear module or an electric push rod. The output end of the drive is connected to the bottom of the seat frame 120 through a connecting rod, which can drive the seat frame 120 to move back and forth. When the seat frame 120 is driven to move forward, the first guide member 311 moves horizontally forward in its guide space, the second guide member 312 moves upward forward in its guide space, and the third guide member 121 at the lower end of the back frame 110 moves upward forward along the third guide rail 210, forcing the back frame 110 to flip around its pivot point with the seat frame 120, thereby increasing the backrest angle and adapting to the ergonomic curve.
