Description

Technical Field

[0001] This utility model relates to the field of health massage equipment technology, specifically to a foot massage device. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, foot massagers (foot therapy machines) have been widely used in homes and offices as a daily health care device. Existing foot therapy machines usually use motors to drive massage heads or massage rollers to press and knead the soles of the feet to relieve foot fatigue and promote blood circulation.

[0003] Existing foot massagers typically only offer simple rotational movements or fixed-position vibration massage, resulting in a simplistic massage method that fails to create a dynamic, three-dimensional pressing and kneading effect on the soles of the feet. While some foot massagers incorporate movable massage structures, their motion conversion mechanisms are complex, resulting in low transmission efficiency. Furthermore, the foot swing seat lacks effective support and guidance during movement, leading to poor motion stability and impacting massage comfort and the overall lifespan of the machine.

The foot swing seat includes a mounting body and a massage rotating wheel rotatably disposed in the mounting body; one end of the drive shaft passes through the bearing seat in the support mechanism near the drive motor and is connected to one end of the massage rotating wheel; the other end of the massage rotating wheel is connected to a rotating shaft, which passes through the bearing seat in the support mechanism away from the drive motor. The linkage mechanism includes a moving crossbar, a first connecting rod, and a second connecting rod. The massage rotating wheel has an eccentrically positioned cylinder. The two ends of the moving crossbar are respectively embedded in the two strip-shaped limiting grooves. One end of the first connecting rod is hinged to the lower surface of the mounting base corresponding to the position of the forefoot or heel of the foot. The other end of the first connecting rod is hinged to the moving crossbar. One end of the second connecting rod is hinged to the cylinder, and the other end of the second connecting rod is hinged to the moving crossbar.

[0006] Furthermore, the cross-sectional shape of the first connecting rod along its length is arc-shaped.

[0007] Furthermore, the central angle corresponding to the first link is 90°.

[0008] Furthermore, the massage rotating wheel also includes two first cylinders respectively disposed on opposite sides of the main cylinder. The two first cylinders have equal diameters and are coaxially arranged, with a gap between them. The two ends of each cylinder are fixedly connected to the opposite surfaces of the two first cylinders. Each cylinder is eccentrically arranged relative to the axis of the first cylinder, and the diameter of each cylinder is smaller than the diameter of the first cylinder.

[0009] Furthermore, the cylinder is composed of a protruding post and a protruding slot that cooperate with each other. The post and the slot are arranged opposite each other and are respectively arranged on the opposite surfaces of the two first cylinders. After they are inserted into each other, the cylinder is formed.

[0010] Furthermore, the first cylinder has a plurality of crescent-shaped protrusions on its circumferential surface, and the plurality of crescent-shaped protrusions are spaced apart along the circumference.

[0011] Furthermore, the foot swing seat also includes a first massage element positioned corresponding to the heel of the foot. The side of the first massage element has a through groove. The mounting body has a horizontal round rod positioned corresponding to the side of the first massage element, and the horizontal round rod passes through the groove. One end of the first massage element is fixed with a connecting rod, and the end of the connecting rod away from the first massage element has a ring.

A linkage mechanism (including a moving crossbar, a first connecting rod, and a second connecting rod) drives the second connecting rod via an eccentrically positioned cylinder on the massage rotating wheel. This, in turn, causes the moving crossbar to move vertically back and forth along the strip-shaped limiting groove. The first connecting rod then transmits the motion of the moving crossbar to the mounting body, enabling the mounting body to swing back and forth during movement, thus achieving dynamic foot massage. This structure converts the rotational motion of the massage rotating wheel into the swinging motion of the mounting body. It is compact, highly efficient in transmission, and enhances the three-dimensionality and comfort of the massage. Simultaneously, the strip-shaped limiting groove limits and guides the vertical movement of the moving crossbar, ensuring the stability and reliability of the foot swing seat's movement.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] The technical solution of this utility model will be described in detail below with reference to specific embodiments.

[0020] See Figures 1 to 11As shown, this embodiment provides a foot massage device, including a base 1, a drive motor 2, a support mechanism 3, a foot swing seat 4, a transmission shaft 5, and a linkage mechanism 6.

[0021] The base 1 is the supporting foundation component, and is horizontally positioned to support and install all other components. The base 1 can be designed as a flat structure, and its bottom can be equipped with anti-slip pads to ensure the stability of the entire unit.

[0022] The drive motor 2 is fixedly mounted on the base 1, and its output shaft is horizontally positioned to provide power to the entire foot massage device. The drive motor 2 can be a geared motor, with its output shaft speed reduced to meet the appropriate rotational speed required for foot massage. The drive motor 2 can be bolted to a support or bracket on the base 1 to ensure stability during operation. The output shaft of the drive motor 2 is connected to the transmission shaft 5. Specifically, a worm gear can be mounted on the transmission shaft 5, or a transmission gear can be installed in its middle to mesh with the worm or gear on the motor output shaft, thereby transmitting power from the drive motor 2 to the transmission shaft 5.

[0023] A support mechanism 3 is mounted on the base 1 and positioned on one side corresponding to the drive motor 2. The support mechanism 3 supports the foot swing seat 4. The support mechanism 3 includes two opposing and spaced-apart upright plates 31, both vertically fixed to the base 1 and extending upwards. The distance between the two upright plates 31 is adapted to the width of the mounting body 41, allowing the mounting body 41 to be positioned precisely between the two upright plates 31 and to move between them. Each upright plate 31 has a bearing seat 311 at its top, housing a bearing to support the end of the rotating component. Each upright plate 31 has a vertically extending strip-shaped limiting groove 312, which is an elongated hole penetrating the thickness direction of the upright plate 31 and extending vertically along its length. The two strip-shaped limiting grooves 312 are arranged opposite each other, meaning they are at the same horizontal height and their openings face each other, facilitating the insertion of the two ends of the movable crossbar 61.

[0024] The foot swing seat 4 includes a mounting body 41 and a massage roller 42 rotatably disposed within the mounting body 41. The mounting body 41 is the main support frame structure of the foot swing seat 4, and is shell-shaped or frame-shaped, used to accommodate and mount other massage components. The massage roller 42 is rotatably disposed within the mounting body 41, meaning that the massage roller 42 can rotate freely relative to the mounting body 41 around its own axis. The circumferential surface of the massage roller 42 is used to contact the sole of the foot and massage the sole.

[0025] One end of the drive shaft 5 passes through the bearing seat 311 near the drive motor 2 in the support mechanism 3 and is connected to one end of the massage rotating wheel 42. Specifically, the drive shaft 5 passes through the bearing seat 311 at the top of the upright plate 31 near the drive motor 2. The bearing in the bearing seat 311 provides rotational support for the drive shaft 5. The end of the drive shaft 5 is fixedly connected to one end of the massage rotating wheel 42 or connected via a coupling, so that the drive shaft 5 can drive the massage rotating wheel 42 to rotate synchronously when it rotates. The other end of the massage rotating wheel 42 is connected to a rotating shaft, which passes through the bearing seat 311 away from the drive motor 2 in the support mechanism 3. In other words, the bearing seat 311 at the top of the upright plate 31 away from the drive motor 2 provides rotational support for this rotating shaft. Thus, both ends of the massage rotating wheel 42 are supported between two bearing seats 311 by the drive shaft 5 and the rotating shaft, respectively, allowing the massage rotating wheel 42 to rotate smoothly within the mounting body 41.

[0026] The linkage mechanism 6 includes a moving crossbar 61, a first connecting rod 62, and a second connecting rod 63. An eccentrically positioned cylinder 421 is provided on the massage rotating wheel 42, meaning the central axis of the cylinder 421 does not coincide with the rotation axis of the rotating wheel, and there is an eccentric distance between them. When the eccentric cylinder 421 rotates with the massage rotating wheel 42, its center moves in a circular motion around the axis of the massage rotating wheel 42. The radial cross-section of the moving crossbar 61 is circular, and both ends of the moving crossbar 61 are respectively embedded in two strip-shaped limiting grooves 312. That is, both ends of the moving crossbar 61 pass through the strip-shaped limiting grooves 312 on the two upright plates 31, and can slide freely in the vertical direction within the strip-shaped limiting grooves 312. The strip-shaped limiting grooves 312 constrain and guide the movement trajectory of the moving crossbar 61. One end of the first connecting rod 62 is hinged to the lower surface of the mounting base 41 corresponding to the forefoot position via a hinge or pin, meaning the first connecting rod 62 can rotate relative to the mounting base 41 around the hinge point. Alternatively, one end of the first connecting rod 62 can also be hinged to the lower surface of the mounting base 41 corresponding to the heel position via a hinge or pin, allowing the first connecting rod 62 to rotate relative to the mounting base 41 around the hinge point. This embodiment uses the forefoot as an example. The other end of the first connecting rod 62 has a through hole, which is fitted onto the movable crossbar 61, allowing this end of the first connecting rod 62 to rotate around the movable crossbar 61. One end of the second connecting rod 63 has a through hole, which is fitted onto the cylinder 421 of the rotating wheel, allowing relative rotation between the second connecting rod 63 and the cylinder 421. The other end of the second connecting rod 63 also has a through hole, which is fitted onto the movable crossbar 61, allowing relative rotation between the second connecting rod 63 and the movable crossbar 61.

[0027] The operating principle of this foot massage device is as follows: After the drive motor 2 is started, the output shaft of the drive motor 2 drives the transmission shaft 5 to rotate, and the transmission shaft 5 drives the rotating wheel to rotate within the mounting base 41. The eccentric cylinder 421 on the massage rotating wheel 42 moves in a circular motion with the rotating wheel, and one end of the second connecting rod 63 sleeved on the cylinder 421 moves accordingly. Since the other end of the second connecting rod 63 is sleeved on the moving crossbar 61, and the moving crossbar 61 is restricted by the strip-shaped limiting groove 312 to move only in the vertical direction, the second connecting rod 63 converts the eccentric rotational motion of the cylinder 421 into the vertical reciprocating motion of the moving crossbar 61 along the strip-shaped limiting groove 312. The reciprocating motion of the moving crossbar 61 is transmitted to the mounting base 41 via the first connecting rod 62. Since one end of the first connecting rod 62 is hinged to the mounting base 41 and the other end is sleeved on the moving crossbar 61, the moving crossbar 61 drives the mounting base 41 to reciprocate around its support axis that mates with the bearing seat 311 when it rises and falls. The oscillation of the mounting base 41 causes the massage rotating wheel 42 and other massage components inside it to move synchronously with the mounting base 41, producing a dynamic pressing and kneading effect on the sole of the foot placed on the foot swing seat 4.

[0028] The above technical solution supports and guides the foot swing seat 4 through a support mechanism 3, and uses a linkage mechanism 6 to drive the second connecting rod 63 via an eccentrically positioned cylinder 421 on the massage rotating wheel 42. This, in turn, causes the moving crossbar 61 to move vertically back and forth along the strip-shaped limiting groove 312. The movement of the moving crossbar 61 is then transmitted to the mounting body 41 via the first connecting rod 62, allowing the mounting body 41 to swing back and forth during movement, thus achieving dynamic foot massage. This structure converts the rotational motion of the massage rotating wheel 42 into the swinging motion of the mounting body 41, resulting in a compact structure, efficient transmission, and improved three-dimensionality and comfort of the massage. Simultaneously, the strip-shaped limiting groove 312 limits and guides the vertical movement of the moving crossbar 61, ensuring the stability and reliability of the foot swing seat 4's movement.

[0029] Based on the above embodiments, the cross-sectional shape of the first connecting rod 62 along its length is arc-shaped, meaning the first connecting rod 62 is an arc-shaped plate or arc-shaped rod as a whole. The arc-shaped first connecting rod 62 possesses unique mechanical characteristics when transmitting motion. Its arc structure can more smoothly convert the vertical lifting motion of the moving crossbar 61 into the swinging motion of the mounting base 41, reducing impact and jamming during motion transmission. Compared to straight-bar connectors, the arc-shaped first connecting rod 62 exhibits a more gradual angle change between its connection point with the mounting base 41 and the moving crossbar 61 during movement, resulting in a smoother and more gentle swinging motion of the mounting base 41. This avoids the jerking sensation caused by sudden angle changes, thereby improving user comfort.

[0030] Based on the above embodiment, the central angle corresponding to the first connecting rod 62 is 90°. The central angle refers to the angle formed by the lines connecting the two ends of the arc of the first connecting rod 62 to the center of the circle. Setting the central angle of the first connecting rod 62 to 90° ensures that the first connecting rod 62 has a suitable arc range during movement. This guarantees that the mounting base 41 has sufficient swing amplitude to achieve effective massage actions, while avoiding increased space occupation and motion interference problems caused by excessive arc. At the same time, the 90° central angle makes the angle relationship between the force direction and the movement direction at both ends of the first connecting rod 62 more reasonable, achieving a better mechanical characteristic of motion transmission, improving the stability and response speed of the swing of the mounting base 41, and making the massage action more sensitive and precise.

[0031] Based on the above embodiment, the massage rotating wheel 42 further includes two first cylinders 43 respectively disposed on opposite sides of the cylinder 421. The two first cylinders 43 have equal diameters, are coaxially arranged and opposite to each other, and are spaced apart, meaning they do not directly contact each other and have a gap in between. The outer circumferential surfaces of the two first cylinders 43 together constitute the main circumferential surface of the massage rotating wheel 42 for contact with the sole of the foot. The cylinder 421 is located between the two first cylinders 43, and both ends of the cylinder 421 are fixedly connected to the opposite surfaces of the two first cylinders 43 to form an integral component, that is, the left end of the cylinder 421 is fixedly connected to the right side of the left first cylinder 43, and the right end of the cylinder 421 is fixedly connected to the left side of the right first cylinder 43, forming an integral component. The cylinder 421 is eccentrically positioned relative to the axis of the first cylinder 43, meaning that the central axis of the cylinder 421 does not coincide with the central axis of the first cylinder 43, and there is an eccentric distance between them. The diameter of the cylinder 421 is smaller than the diameter of the first cylinder 43, so that the cylinder 421 is located entirely within the interval region between the two first cylinders 43, and its outer circumference does not extend beyond the outer circumference of the first cylinder 43.

[0032] This integrated eccentric wheel structure allows the cylinder 421, acting as an eccentric column, to generate eccentric motion as the massage rotating wheel 42 rotates around the axis of the first cylinder 43, providing a stable driving power source for the linkage mechanism 6. The two first cylinders 43 are coaxially arranged and have equal diameters, ensuring dynamic balance during the overall rotation of the massage rotating wheel 42, reducing vibration and noise during rotation, and improving the smoothness and service life of the entire machine. The diameter of cylinder 421 is smaller than the diameter of the first cylinder 43, ensuring that the movement of cylinder 421 does not exceed the outer edge of the first cylinder 43, making the overall structure more compact.

[0033] Based on the above embodiment, the cylinder 421 is composed of a protruding insert 4211 and a protruding slot 4212 that cooperate with each other. The insert 4211 is a cylindrical structure that protrudes outward along the axial direction from the opposite surface of one of the first cylinders 43, and the slot 4212 is a groove structure that is disposed on the opposite surface of the other first cylinder 43 and recessed inward along the axial direction. The insert 4211 and the slot 4212 are arranged opposite to each other, that is, they are located on the same axis and are arranged facing each other. The outer diameter of the insert 4211 is adapted to the inner diameter of the slot 4212, and the insert 4211 can be inserted into the slot 4212. After the two are inserted into each other, a complete cylinder 421 structure is formed.

[0034] By configuring the cylinder 421 with a structure in which the insert 4211 and the slot 4212 are interlocked, the assembly of the massage rotating wheel 42 becomes more convenient, reducing the processing difficulty and assembly cost of the parts. The interlocking mechanism of the insert 4211 and the slot 4212 ensures the connection strength of the cylinder 421 under stress, while facilitating the modular production and assembly of different components, thus improving production efficiency.

[0035] Based on the above embodiment, the circumferential surface of the first cylinder 43 is provided with a plurality of crescent-shaped protrusions. Crescent-shaped means that the projection of the protrusion's shape in the circumferential direction is a half-moon shape; that is, the protrusion has an arc-shaped outline, its cross-section along the circumferential direction extends in an arc shape, and one end is wider than the other, presenting an overall shape similar to a crescent moon. The plurality of crescent-shaped protrusions are arranged at intervals along the entire circumference of the first cylinder 43, that is, the protrusions are evenly or non-uniformly distributed along the circumferential direction of the first cylinder 43, with a gap between adjacent protrusions.

[0036] As the massage roller 42 rotates, these crescent-shaped protrusions rotate synchronously with the first cylinder 43. Because the protrusions extend outward from the circumferential surface of the first cylinder 43, when the massage roller 42 rotates within the mounting base 41, the protruding portions of the protrusions can provide intermittent rolling pressure to the middle of the sole (i.e., the arch area). The unique crescent shape gives each pressure a certain directionality and variation—as the roller rotates, the contact area and position between the protrusions and the sole gradually change, providing progressive stimulation to acupoints in the arch area, helping to relieve foot fatigue, promote blood circulation, and enhance the massage effect and smoothness of the middle of the sole.

[0037] Based on the above embodiments, the foot swing seat 4 further includes a first massage element 44 positioned corresponding to the heel area of ​​the foot. The first massage element 44 is located within the mounting body 41 corresponding to the heel area of ​​the user's foot. A through groove 441 is provided on the side of the first massage element 44. The groove 441 is an elongated through-slot that extends through the thickness direction of the first massage element 44, and its length extends along the direction of movement of the first massage element 44. A horizontal round rod 411 is provided on the mounting body 41 corresponding to the side of the first massage element 44. The horizontal round rod 411 is fixedly mounted on the mounting body 41 and extends horizontally. The horizontal round rod 411 passes through the groove 441, meaning the groove 441 fits onto the horizontal round rod 411, allowing the first massage element 44 to slide back and forth along the axial direction of the horizontal round rod 411, i.e., the length direction of the groove 441. The horizontal rod 411 passes through the slide groove 441, which restricts and guides the range of motion of the first massage member 44, so that the first massage member 44 can only slide relative to the horizontal rod 411 along the length direction of the slide groove 441, and the movement in other directions is constrained.

[0038] A connecting rod 442 is fixed to one end of the first massage element 44. Specifically, one end of the connecting rod 442 is fixedly connected to the end of the first massage element 44 and extends outward from that end. A ring 4421 is provided at the end of the connecting rod 442 away from the first massage element 44. The ring 4421 has a ring structure. The ring 4421 is sleeved on the cylinder 421 of the rotating wheel, and the ring 4421 and the cylinder 421 can rotate relative to each other. That is, the inner diameter of the ring 4421 is larger than the outer diameter of the cylinder 421, and a clearance fit is formed between the two or a bearing is provided, so that the ring 4421 can rotate freely relative to the cylinder 421.

[0039] The operating principle of this structure is as follows: When the massage wheel 42 rotates, the cylinder 421, acting as an eccentric cylinder, performs circular motion around the axis of the massage wheel 42. The ring 4421, fitted onto the cylinder 421, moves along with the cylinder 421. Since the ring 4421 is fixedly connected to the first massage element 44 via the connecting rod 442, and the first massage element 44 is restricted to sliding only in the horizontal direction by the cooperation of the horizontal rod 411 and the groove 441, the eccentric rotational motion of the cylinder 421 is converted into the reciprocating linear sliding of the first massage element 44 along the direction of the horizontal rod 411 through the transmission of the ring 4421 and the connecting rod 442. The upper surface of the first massage element 44 has multiple discretely distributed hemispherical protrusions, with the spherical surface of these hemispherical protrusions facing upwards for direct contact with the sole of the foot. When the first massage element 44 slides reciprocally, the hemispherical protrusions on its upper surface generate reciprocating sliding pressure on the heel area of ​​the sole of the foot. Meanwhile, the discretely distributed hemispherical protrusions can provide multi-point pressure stimulation to the heel area, effectively relieving heel fatigue and enhancing the massage effect on the ball of the foot. The cooperation between the slide groove 441 and the horizontal round rod 411 precisely guides the movement of the first massage element 44, ensuring the smoothness of the reciprocating motion.

[0040] Based on the above embodiment, the foot swing base 4 further includes a second massage member 45 positioned corresponding to the forefoot area. The second massage member 45 is fixedly installed within the mounting base 41, meaning there is a fixed connection between the second massage member 45 and the mounting base 41, with no relative movement between them. The second massage member 45 is located within the mounting base 41 corresponding to the forefoot area of ​​the user's foot, i.e., the metatarsal region. The upper surface of the second massage member 45 has multiple discretely distributed hemispherical protrusions, with the spherical surfaces of these protrusions facing upwards for direct contact with the forefoot area.

[0041] Since the second massage element 45 is fixedly mounted on the mounting base 41, when the mounting base 41 moves with the foot swing seat 4, for example, when it swings with the first connecting rod 62, the second massage element 45 moves synchronously with the mounting base 41. Its hemispherical protrusions provide a fixed pressing stimulation to the forefoot area. Unlike the reciprocating sliding pressing of the first massage element 44, the second massage element 45 provides relatively stable, point-based pressing that rises and falls with the overall movement of the mounting base 41, continuously stimulating acupoints in the forefoot area and helping to relieve forefoot fatigue. The reciprocating motion of the first massage element 44 and the fixed undulating motion of the second massage element 45 complement each other, achieving a combination of different massage methods for the front and back areas of the foot, thus enhancing the overall massage effect.

[0042] Based on the above embodiment, there are two support mechanisms 3, which are respectively set on the base 1 and on opposite sides of the drive motor 2, that is, one support mechanism 3 is set on the left side of the drive motor 2 and one support mechanism 3 is set on the right side. Each support mechanism 3 includes two opposite and spaced upright plates 31, that is, there are four upright plates 31 in total, and every two upright plates 31 form a group of support mechanisms 3. The output shaft of the drive motor 2 is connected to the middle of the transmission shaft 5, that is, the transmission shaft 5 passes laterally through the area where the drive motor 2 is located, and the output shaft of the drive motor 2 inputs power to the transmission shaft 5 from the middle position. The two ends of the transmission shaft 5 are respectively connected to the rotating wheels of the two foot swing seats 4, that is, the left end of the transmission shaft 5 is connected to the rotating wheel of the left foot swing seat 4 and the right end is connected to the rotating wheel of the right foot swing seat 4.

[0043] By setting two support mechanisms 3, each corresponding to one of the opposite sides of the drive motor 2, and connecting both ends of the drive shaft 5 to the massage rotating wheels 42 of the two foot swing seats 4, a single drive motor 2 can simultaneously drive the movement of both left and right foot swing seats 4, achieving power source sharing and reducing cost and energy consumption. The symmetrical arrangement of the two support mechanisms 3 ensures the structural balance of the entire machine, and the simultaneous output of power from both ends of the drive shaft 5 ensures good synchronization of the movement of the left and right foot swing seats 4, improving the overall working efficiency and massage consistency of the machine.

[0044] Based on the above embodiment, the two foot swing seats 4 are symmetrically arranged with respect to the drive motor 2, that is, with the drive motor 2 as the center, the left foot swing seat 4 and the right foot swing seat 4 are symmetrically arranged in the left-right direction of the base 1. The transmission shaft 5 is horizontally arranged, and both ends of the transmission shaft 5 are respectively connected to the massage rotating wheels 42 of the two foot swing seats 4, that is, the left end of the transmission shaft 5 is connected to the left rotating wheel and the right end is connected to the right rotating wheel. The output shaft of the drive motor 2 is horizontally arranged, so that the output shaft of the drive motor 2 is parallel or coaxial with the transmission shaft 5, and the two can transmit power through gear transmission or worm gear transmission.

[0045] By symmetrically arranging the two foot swing seats 4 relative to the drive motor 2, and by horizontally arranging both the transmission shaft 5 and the output shaft of the drive motor 2, the center of gravity of the entire machine is located in the central area of ​​the base 1. The force on the transmission shaft 5 is symmetrically distributed along the axial direction, avoiding the occurrence of off-center loading, ensuring uniform force on the transmission shaft 5, and smooth movement of the two foot swing seats 4, thereby improving the stability and service life of the entire machine. The horizontally arranged transmission path also helps to reduce energy loss during power transmission and improve transmission efficiency.
