Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a foot swing structure, a lower limb massager, and a massage chair. Background Technology

[0002] In recent years, with the popularization of healthy lifestyles, calf and foot massage and relaxation products have seen rapid growth in the market. A large number of calf massagers with functions such as foot kneading, pressing, and roller massage are available, featuring diverse structural designs, such as airbag compression, 3D roller, and heat-vibration types, to meet the basic foot relaxation needs of different users. However, in comparison, designs for foot stretching functions lag behind. Most products still rely on simple mechanical synchronized swinging modes, causing the feet to swing up and down at the same angle and rhythm, simulating traditional manual stretching. While this design can stretch the feet, the monotonous movement mode lacks fun and engagement, easily leading to user fatigue and a monotonous experience after long-term use. Utility Model Content

The use of terms such as "upper," "lower," "left," "right," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is only for the convenience of describing this utility model, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] Furthermore, in the description of this utility model, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0037] Please see Figures 1-14 As shown, this utility model discloses a foot-swinging structure, including a support frame 1 and two swinging members 2 that can support a person's feet and are distributed left and right. Each swinging member 2 is a foot pedal structure that can support the feet, and each swinging member 2 can swing up and down. This utility model also includes a first drive mechanism 3 and two second drive mechanisms 4. The first drive mechanism 3 is mounted on the support frame 1 and connected to the two swinging members 2 to drive the two swinging members 2 to swing up and down alternately. The two second drive mechanisms 4 are respectively mounted on the support frame 1 and connected to each of the two swinging members 2 to drive the two swinging members 2 to swing up and down respectively.

[0038] In a preferred embodiment, the inner ends of the two swing members 2 are respectively provided with first rotating shafts 21 extending towards each other and coaxially arranged, and the outer ends of the two swing members 2 are respectively provided with second rotating shafts 22 extending in opposite directions and coaxially arranged. The second rotating shafts 22 are rotatably connected to the support frame 1 around their axes and are coaxially arranged with the first rotating shafts 21. Therefore, the swing members 2 swing up and down around the axes of the first rotating shafts 21 and the second rotating shafts 22. In this embodiment, the first rotating shafts 21 and the second rotating shafts 22 are respectively fixedly connected to the swing members 2, but this is not limited to this. In other embodiments, the first rotating shafts 21 and the second rotating shafts 22 are integrally formed on the swing members 2. The first driving mechanism 3 is drivenly connected to the first rotating shafts 21 of the two swing members 2, and the two second driving mechanisms 4 are drivenly connected to the second rotating shafts 22 of the two swing members 2 one by one. In this way, the connection relationship between the first driving mechanism 3, the two second driving mechanisms 4, the two swing members 2 and the support frame 1 is relatively simple, thereby simplifying the overall structure.

[0039] like Figure 2 , Figure 3 As shown, the first drive mechanism 3 includes a first motor 31, a driving bevel gear 32, two driven bevel gears 33, a first control unit, and a housing 34 fixed to the support frame 1. The first driving bevel gear 32 is driven by the first motor 31, and the working state of the first motor 31 is controlled by the first control unit. The first motor 31 is relatively fixed to the housing 34. The two driven bevel gears 33 are coaxially arranged and rotatably connected to the housing 34 around their axes. Specifically, the housing 34 is provided with a support shaft 35, and the two driven bevel gears 33 are movably sleeved on the support shaft 35. The two driven bevel gears 33 are located between the two swing members 2 and are coaxially fixed to the first rotating shaft 21 of the two swing members 2. Specifically, the center position of each of the two driven bevel gears 33 is provided with a polygonal shaft hole, which is inserted and engaged with the polygonal shaft segment provided on the first rotating shaft 21. The two driven bevel gears 33 mesh with the driving bevel gear 32, so that as the driving bevel gear 32 rotates, the two driven bevel gears 33 rotate in opposite directions.

[0040] The first control unit includes a grating position detection plate 37 and a rocking encoder disk 36. The rocking encoder disk 36 is coaxially and fixedly connected to the drive bevel gear 32. The grating position detection plate 37 is fixedly installed and has a light output section and a light input section. The light output section and the light input section are respectively located on both sides of the axial direction of the rocking encoder disk 36. The grating position detection plate 37 emits light signals to the rocking encoder disk 36 through the light output section and receives light signals reflected or transmitted from the rocking encoder disk 36 through the light input section to detect the swing angle of the rocking encoder disk 36. The rocking encoder disk 36 is circular and has multiple grating holes for indicating its swing angle, such as... Figure 4 As shown, the plurality of grating apertures include a first grating aperture 361 corresponding to the initial position, a second grating aperture 362 corresponding to the left-upper-right-lower swing angle, and a third grating aperture 363 corresponding to the right-lower-left-upper swing angle. The first grating aperture 361, the second grating aperture 362, and the third grating aperture 363 are distributed circumferentially along the swing encoder disk 36, with the first grating aperture 361 located between the second grating aperture 362 and the third grating aperture 363. The grating position detection board 37 is electrically connected to the first motor 31, meaning that the grating position detection board 37 not only has a detection function but also a control function, and can control the working state of the first motor 31 according to the detection result. Alternatively, the output of the grating position detection board 37 can be connected to a control board, which is electrically connected to the first motor 31, so that the control board controls the working state of the first motor 31 according to the detection result of the grating position detection board 37.

[0041] In this embodiment, the output shaft of the first motor 31 is connected to the driving bevel gear 32 via a transmission assembly. The transmission assembly specifically includes a first pulley 38, a second pulley 39, a belt 310, and a reduction gearbox (not shown in the figure). The outer diameter of the first pulley 38 is smaller than the outer diameter of the second pulley 39. The first pulley 38 is located on the output shaft of the first motor 31. The second pulley 39 is coaxially fixed to the input shaft of the gearbox. The belt 310 is wound around the first pulley 38 and the second pulley 39. The output shaft of the reduction gearbox is coaxially fixed to the driving bevel gear 32. Since the swaying encoder 36 is also coaxially fixed to the driving bevel gear 32, the swaying encoder 36 is also coaxially fixed to the output shaft of the reduction gearbox. Specifically, the swaying encoder 36 and the driving bevel gear 32 are sequentially arranged on the output shaft of the reduction gearbox. The outer shell of the reduction gearbox is fixed relative to the aforementioned housing 34. Specifically, the reduction gearbox, the first motor 31, and the grating position detection plate 37 are all installed on the housing 34. The housing 34 is composed of multiple parts and encloses the transmission assembly, the driving bevel gear 32, and two driven bevel gears 33, thereby making the appearance of the entire first drive mechanism 3 relatively simple and beautiful.

[0042] like Figure 3 As shown, the second drive mechanism 4 includes a second motor 41, a second control unit, and a reduction gear assembly driven by the second motor 41. The final gear of the reduction gear assembly is coaxially and fixedly connected to the second rotating shaft 22 of the corresponding swing member 2. The second motor 41 is mounted on the support frame 1, and the working state of the second motor 41 is controlled by the second control unit. Specifically, the reduction gear assembly includes a first helical gear (not shown in the figure), a second helical gear 42, a worm 43, and a worm wheel 44. The first helical gear is fixed to the output shaft of the second motor 41. The worm 43 is rotatably connected to the support frame 1 and coaxially and fixedly connected to the second helical gear 42. The second helical gear 42 meshes with the first helical gear, and the worm 43 meshes with the worm wheel 44. The worm wheel 44 constitutes the final gear, and the worm wheel 44 is integrally formed with the second rotating shaft 22. The worm wheel 44 does not have helical teeth all around its circumference, but only has helical teeth in a portion of its area. This helps to save materials, reduce manufacturing costs, and reduce the weight of the worm wheel 44.

[0043] In this embodiment, the second control unit includes three magnetic components mounted on the final stage gear (i.e., worm gear 44) and a Hall effect detection plate 45 mounted on the support frame 1. The three magnetic components are distributed circumferentially along the final stage gear (i.e., worm gear 44), and the central angle between adjacent magnetic components is consistent with the angle at which the oscillating component 2 swings upward or downward. The angle at which the oscillating component 2 swings upward or downward is set to 30°, therefore, the central angle between adjacent magnetic components is 30°. Specifically, the magnetic components are magnetic rods (not shown in the figure) inserted into the worm gear 44. Therefore, the worm gear 44 has three insertion holes corresponding to the three magnetic components, such as... Figure 6 As shown. The Hall effect sensor 45 is used to detect changes in the magnetic field of the magnetic component (i.e., the magnetic rod) and is electrically connected to the second motor 41. Alternatively, the output of the Hall effect sensor 45 is connected to a control board, which is electrically connected to the second motor 41, and this control board can be the same control board mentioned above.

[0044] The support frame 1 includes a main frame 11 and two support boxes 12. The two support boxes 12 are respectively fixed to the support sheet metal 14 located at the bottom of the left and right ends of the main frame 11, and are spaced apart. Two swinging components 2 are disposed between the two support boxes 12. Two second drive mechanisms 4 are respectively installed in the two support boxes 12, and a first drive mechanism 3 is installed in the main frame 11. Specifically, the housing 34 of the first drive mechanism 3 is installed in the fixed sheet metal 13 located at the bottom middle position of the main frame 11. The support box 12 specifically includes an outer box cover 121 and an inner box cover 122 distributed in the left-right direction. The outer box cover 121 and the inner box cover 122 are connected together and enclose a cavity that can accommodate the reduction gear assembly. The second rotating shaft 22 of the swing member 2 is sleeved in the shaft hole 124 provided in the inner box cover 122. The second motor 41 is installed in the inner box cover 122, and its output shaft extends into the cavity of the support box 12. The Hall detection plate 45 is snapped into the slot 123 provided on the outer side of the outer box cover 121.

[0045] The present invention provides a foot-swinging structure, the initial state of which is as follows: Figure 9 As shown, at this time, the two swinging components 2 are level with each other and slightly tilted downwards at the front. When only the first motor 31 is started, the first motor 31 drives the first belt 310 pulley 38 to rotate, and the first belt 310 pulley 38 drives the second belt 310 pulley 39 to rotate through the belt 310. The power is transmitted to the driving bevel gear 32 through the reduction gearbox. The driving bevel gear 32 drives the two driven bevel gears 33 distributed on the left and right to rotate in opposite directions, thereby realizing the alternating up and down swinging of the two swinging components 2. The maximum amplitude of the up and down swinging of the two swinging components 2 is controlled within 30° by the grating position detection plate 37 and the swing encoder 36. Figure 10 , Figure 11 As shown.

[0046] When only the second motors 41 of the two second drive mechanisms 4 are activated simultaneously, the power of the second motors 41 is transmitted through a first-stage reduction structure consisting of the first helical gear and the second helical gear 42 to a second-stage reduction structure consisting of the worm 43 and the worm wheel 44. The worm wheel 44 then drives the oscillating member 2 to swing, causing both oscillating members 2 to swing upwards or downwards simultaneously. The swing angle of the two oscillating members 2 is controlled within ±30° through the cooperation of the Hall effect sensor 45 and the magnetic rod mounted on the worm wheel 44. Figure 12 , Figure 13 As shown.

[0047] When only one of the second drive mechanisms 4's second motors 41 is activated, the second motor 41 transmits power through a first-stage reduction structure consisting of a first helical gear and a second helical gear 42 to a second-stage reduction structure consisting of a worm 43 and a worm wheel 44. The worm wheel 44 then drives the corresponding oscillating component 2 to swing upwards or downwards. The oscillation angle of the oscillating component 2 is controlled within ±30° through the cooperation of the Hall effect sensor 45 and the magnetic rod mounted on the worm wheel 44. Figure 14 As shown. Since the second motor 41 of the other second drive mechanism 4 is not started, the swing member 2 corresponding to the other second drive mechanism 4 remains in its initial state, as shown. Figure 14 As shown.

[0048] Therefore, by setting the first driving mechanism 3 and the second driving mechanism 4, this utility model can realize the two swinging parts 2 swinging up and down alternately to stretch the tendons, or the two swinging parts 2 swinging up and down synchronously to stretch the tendons or swinging up and down independently to stretch the tendons. This allows the utility model to realize the multi-mode foot stretching function, making the user's physical experience during the stretching process richer, more interesting and playful.

[0051] The present invention relates to a foot swing structure, a lower limb massager, and a massage chair. The parts not described herein are the same as or can be implemented using existing technologies.

[0052] The above embodiments are only used to further illustrate a foot swing structure, lower limb massager and massage chair of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
