[0002] Existing foot massagers often feature simplistic calf massage designs, mostly employing fixed massage heads or simple roller massage structures. These designs suffer from low integration of the transmission system and poor motion coordination. Traditional massage mechanisms cannot achieve the combined action of roller rolling massage and lever-linked squeezing massage; they can only perform superficial rolling and kneading, failing to provide targeted squeezing and kneading depth massage that conforms to the contours of the calf muscles. Furthermore, the simple connection structure between the transmission and massage execution components in existing calf massage mechanisms limits the range of motion and results in a limited massage method. This fails to address both superficial calf soothing and deep muscle relaxation, leading to a poor massage experience and ineffective massage results, thus failing to meet the diverse calf massage needs of users.

[0025] See Figures 1 to 9 As shown, this embodiment provides a calf massage mechanism, including a frame 1 and a drive motor 2, a roller shaft assembly 3, a swing arm 4, a connecting rod 5, a first massage assembly 6, and a second massage assembly 7 respectively mounted on the frame 1; The roller shaft assembly 3 includes a gear component 31 with a transmission shaft 32, and the drive motor 2 is provided with a motor output shaft 21, which is connected to the gear component 31 in a transmission manner; the transmission shaft 32 and the connecting rod 5 are arranged horizontally and parallel to each other; The first massage component 6 includes a roller assembly 61 and a first massage part 62 disposed on the circumferential surface of the roller assembly 61. An eccentrically disposed protrusion 63 is provided on the end face of the roller assembly 61. One end of the swing arm 4 is provided with an annular body 41. The annular body 41 is sleeved on the protrusion 63 and the annular body 41 and the protrusion 63 are slidably connected to each other. The contact surfaces of the annular body 41 and the protrusion 63 are both smooth.

[0026] The second massage assembly 7 includes a massage body 71 and a second massage portion 72 disposed on the massage body 71. The massage body 71 has a through groove 711 through which the connecting rod 5 passes. The other end of the swing rod 4 is fixedly connected to the massage body 71. In this embodiment, the swing rod 4 and the second massage assembly 7 are manufactured using an integral molding process. The second massage portion 72 includes conical protrusions distributed in a 3×3 matrix, with the top of the conical protrusions being a smooth arc shape.

[0027] In this embodiment, the frame 1 serves as the overall load-bearing base, used to fix all transmission and massage components; the drive motor 2 is the power source of the overall mechanism, and the roller shaft assembly 3 is the core transmission and transfer component. Power transmission is achieved through the meshing of the gear 31 with the motor output shaft 21, converting the motor's rotational power into the rotational motion of the transmission shaft 32. The transmission shaft 32 and the connecting rod 5 are arranged horizontally and parallel to each other, ensuring the regularity of the transmission and limiting structure. The first massage component 6 is a rolling massage execution structure, relying on the first massage part 62 on the circumference of the roller assembly 61 to achieve surface rolling massage. The eccentrically positioned protrusion 63 on the end face of the roller assembly 61 is the core of the eccentric transmission. The annular body 41 at the end of the swing arm 4 slides on the protrusion 63, allowing for sliding adaptation to the eccentric trajectory when the protrusion 63 rotates, preventing movement jamming. The second massage component 7 is a compression massage execution structure. The massage body 71 is movable with the connecting rod 5 through the through groove 711 to achieve limited sliding. At the same time, the swing rod 4 is fixedly connected to the massage body 71, which can convert the eccentric rotation power into the reciprocating oscillating compression action of the massage body 71.

[0028] As described above, the core composite massage transmission structure of this utility model is constructed. Unlike the traditional single massage structure, it realizes a composite massage mode of roller rolling massage and swing arm linkage squeezing massage, which fundamentally solves the technical problems of existing calf massage mechanisms that have single movements, can only perform surface massage, and have poor deep muscle relaxation effect. At the same time, the components are compactly coordinated, the power transmission path is short, and the transmission efficiency is high, providing a core structural foundation for the stable operation of the equipment.

[0029] Furthermore, the drive motor 2 is located at the horizontal center of the frame 1, and the first massage component 6 and the second massage component 7 form a set of calf massage execution components. The two sets of calf massage execution components are symmetrically distributed on both sides of the drive motor 2 with the drive motor 2 as the axis of symmetry, and are set corresponding to the two calf positions.

[0030] In this embodiment, the overall layout structure of the massage component is defined. The drive motor 2 is centrally installed in the horizontal middle of the frame 1. Two sets of calf massage execution components are symmetrically arranged with the drive motor 2 as the center. Each execution component consists of a first massage component 6 and a second massage component 7. The two sets of execution components are respectively arranged corresponding to the calf positions of the human body's two legs. The left and right structures are completely symmetrical and can complete the massage operation of both legs simultaneously.

[0031] As described above, the symmetrical layout conforms to the symmetrical physiological structure of the human legs, enabling simultaneous and uniform compound massage of both legs. The massage intensity and trajectory are consistent for both legs, avoiding the uneven experience caused by unilateral massage, and greatly improving the massage adaptability and ease of use.

[0032] Furthermore, the drive shaft 32 and the connecting rod 5 are arranged vertically, with the drive shaft 32 located directly above the connecting rod 5.

[0033] In this embodiment, the relative positions of the drive shaft 32 and the connecting rod 5 are defined. The drive shaft 32 and the connecting rod 5 are arranged vertically, with the drive shaft 32 located directly above the connecting rod 5. The two are kept horizontally parallel, with the upper part being the power transmission end and the lower part being the limiting support end, forming a transmission limiting structure that corresponds vertically and cooperates stably.

[0034] As described above, the layered layout is neat and orderly, effectively avoiding interference between the drive shaft 32 and the connecting rod 5. At the same time, it forms a force-bearing structure with upper and lower alignment, improving the stability of the swing arm 4 swinging and the massage body 71 sliding process, preventing component offset and shaking, and ensuring the accuracy of transmission and massage actions.

[0035] Furthermore, the roller assembly 61 includes two opposing first rollers 611 and second rollers 612, with the protrusion 63 disposed on the opposing end faces of the first roller 611 and the second roller 612. Specifically, the first roller 611 has a first protrusion on its end face facing the second roller 612, and the first protrusion has a first insertion portion. The second roller 612 has a second protrusion on its end face facing the first roller 611, and the second protrusion has a second insertion portion. The first insertion portion and the second insertion portion are interlocked, so that the first protrusion and the second protrusion are flush with each other, together forming the protrusion. That is to say, the first protrusion and the second protrusion are each part of the protrusion.

[0036] In this embodiment, the roller assembly 61 consists of a first roller 611 and a second roller 612 arranged in parallel, working in pairs. The protrusion adopts a split-joint assembly structure. A first protrusion is provided on the end face of the first roller 611 facing the second roller 612, and a first insertion part is provided on the inner side of the first protrusion; a second protrusion is provided on the end face of the second roller 612 facing the first roller 611, and a second insertion part is provided on the inner side of the second protrusion. Through the mutual insertion and limiting cooperation of the first insertion part and the second insertion part, the first protrusion and the second protrusion are precisely connected and their end faces are flush. The two are spliced ​​together to form a complete protrusion structure. Relying on the split-joint protrusion structure of the double rollers, stable rolling support and eccentric transmission functions are achieved.

[0037] As described above, the dual-roller split-type plug-in composite protrusion structure offers higher assembly precision compared to a one-piece protrusion. The plug-in connection ensures precise alignment and flushing of the first and second protrusions, effectively preventing uneven force distribution and wobbling on one side of the protrusion, significantly improving the stability and coaxiality of the eccentric transmission. The split-type structure reduces the molding and processing difficulty of individual rollers, making component disassembly, assembly, maintenance, and replacement more convenient. Simultaneously, the symmetrically connected protrusions on both sides experience more balanced force, effectively enhancing the stability of the rolling massage support, increasing the area of ​​contact with the calf skin for massage, and ensuring a uniform and stable massage effect.

[0038] Furthermore, the first massage portion 62 includes two or more protrusions evenly distributed along the circumferential surfaces of the first roller 611 and the second roller 612, and the cross-sectional shape of the protrusions is crescent-shaped.

[0039] In this embodiment, the specific structure of the first massage part 62 is defined. The first massage part 62 is composed of two or more protrusions that are evenly arranged. All protrusions are distributed at equal intervals along the circumference of the roller to ensure the uniformity of the rolling massage. The protrusions adopt a crescent-shaped cross-section structure, which is different from the conventional circular and square protrusion structures. The arc-shaped surface fits the curve of the human skin better.

[0040] As described above, the multiple evenly arranged protrusions can achieve continuous, seamless rolling massage. The crescent-shaped structure has a soft touch, which can ensure the pressure stimulation effect on the calf fascia without causing hard protrusions to squeeze and sting the skin, greatly optimizing the massage feel and balancing massage strength and comfort.

[0041] Furthermore, the number of protrusions on both the first roller 611 and the second roller 612 is three.

[0042] In this embodiment, both the first roller 611 and the second roller 612 are provided with three protrusions, which are evenly distributed at 120° along the circumference of the rollers to form a regular circumferential massage structure.

[0043] As can be seen from the above description, the ratio of the three sets of protrusions is the optimal structure. It avoids the problems of large massage gaps and discontinuous massage caused by too few protrusions, and avoids the defects of dispersed massage intensity and insufficient stimulation caused by too many protrusions, thus achieving the optimal balance between massage continuity and massage intensity.

[0044] Furthermore, the connecting rod 5 is provided with retaining rings 51, and the two retaining rings 51 are respectively located on both sides of the through groove 711.

[0045] In this embodiment, two retaining springs 51 are mounted on the connecting rod 5. The two retaining springs 51 are respectively positioned on the left and right sides of the through groove 711 of the massage body 71 to limit and block the left and right sliding stroke of the massage body 71.

[0046] As described above, by using double-sided retaining rings 51 to limit the sliding stroke of the massage body 71 on the connecting rod 5, the excessive sliding of the massage body 71 can be prevented from causing deviation, detachment, or motion interference, thereby effectively improving the stability and safety of the mechanism and extending the service life of the equipment.

[0047] Furthermore, the cross-section of the through groove 711 is formed in an arc shape.

[0048] In this embodiment, the structure of the through groove 711 of the massage body 71 is defined. The through groove 711 adopts an arc-shaped cross-section design, and the inner wall of the arc is adapted to the curved surface of the cylindrical rod of the connecting rod 5. The two are in a curved surface fit and sliding fit.

[0049] As described above, the arc-shaped through groove 711 fits the connecting rod 5 better. Compared with the square through groove 711, it has no sharp edge friction, which greatly reduces wear and noise during the sliding process. At the same time, the curved surface has better adaptability, and the massage body 71 swings and slides more smoothly without jamming, improving the quietness and smoothness of the equipment operation.

[0050] Furthermore, the frame 1 is provided with a housing 11, and the housing 11 has a cavity that can accommodate the gear 31. The housing 11 forms bearing seats on both sides of the cavity, and bearings 12 are installed in the bearing seats. The transmission shaft 32 passes through the bearing 12 on one side, the gear 31 and the bearing 12 on the other side in sequence. The motor output shaft 21 extends into the housing 11 and meshes with the gear 31.

[0051] In this embodiment, the packaging and support structure of the gear transmission is refined. A housing 11 is fixedly installed on the frame 1. The housing 11 has a dedicated cavity inside to house the gear component 31, achieving closed protection for the transmission gear. Bearing seats are integrally formed on both sides of the cavity of the housing 11, and bearings 12 are embedded inside the bearing seats. The transmission shaft 32 passes through the bearings 12 on both sides and the gear component 31 in the middle, achieving rotational support. The motor output shaft 21 extends into the cavity of the housing 11 and precisely meshes with the gear component 31 to complete the power input.

[0052] As described above, the housing 11 can provide enclosed protection for the gear transmission structure, effectively preventing dust and debris from entering the transmission parts and avoiding gear jamming and wear; the double-sided bearing support structure greatly improves the coaxiality and stability of the transmission shaft 32 rotation, reduces transmission noise and wear, ensures accurate and efficient power transmission, and improves the reliability and durability of the overall mechanism.

[0053] The working principle of this embodiment: After the device is started, the drive motor 2 runs, and the motor output shaft 21 drives the gear component 31 to rotate through gear meshing, which drives the transmission shaft 32 to rotate synchronously. The roller assembly 61 at the end of the transmission shaft 32 rotates with it, and the crescent-shaped protrusion on the circumference continuously rolls and massages the surface of the calf. At the same time, the eccentric protrusion 63 on the end face of the roller moves eccentrically with the transmission shaft 32, and drives the swing arm 4 to swing back and forth through the sliding engagement of the ring body 41. The swing arm 4 drives the fixedly connected massage body 71, and through the limited sliding engagement of the arc through groove 711 and the connecting rod 5, a stable reciprocating squeezing action is achieved. Through the second massage part 72, the deep muscles of the calf are squeezed and kneaded, and finally a compound calf massage effect of rolling relaxation and squeezing kneading is achieved.

[0054] In the above Figures 1 to 9 Based on this, continue to refer to Figures 10 to 12 As shown, this embodiment also provides a foot massager, including the aforementioned calf massage mechanism.

[0055] In this embodiment, the foot massager equipped with the aforementioned calf massage mechanism integrates the body, the foot massage structure, and the calf massage mechanism of this embodiment. The calf massage mechanism, as the core massage module, is fixedly installed at the position of the foot massager corresponding to the calf support.

[0056] As described above, integrating a highly adaptable and effective composite calf massage mechanism into a foot massager achieves a combined function of foot massage and calf massage, enriching the functional dimensions of the foot massager and enhancing the overall product's usability and market competitiveness.

[0057] This utility model has been described with reference to the above-described embodiments and accompanying drawings. However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. On the contrary, modifications and equivalent provisions included in the spirit and scope of the claims are all included within the scope of this utility model.
