[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 10 As shown, this application provides a massage device 100, including a frame 10, a guide rail 20, and a massage mechanism 30. The guide rail 20 is disposed on the frame 10 and includes a sliding section. The massage mechanism 30 travels along the sliding section and has a groove 311 through which the sliding section passes. The two ends of the guide rail 20 are fixed to the frame 10, and there is a preset gap between the sliding section and the frame 10. The preset gap is configured to provide deformation space for the sliding section when it deforms with the frame 10.

[0024] When the frame 10 deforms due to external forces, vibration, impact, or long-term load, the preset gap can provide sufficient deformation space for the sliding section, which helps to avoid stress concentration, thereby significantly reducing the risk of structural fatigue of the guide rail 20, preventing surface damage and geometric accuracy deviation, and ensuring that the massage mechanism 30 moves stably along the guide rail 20.

[0025] In this embodiment, as Figures 1 to 4 As shown, the structure of the frame 10 is not strictly limited, as long as the frame 10 can support components such as the massage mechanism 30. The frame 10 includes a fixed plate 12 and a sponge 13 surrounding the fixed plate 12; wherein, the two ends of the guide rail 20 are fixed to the fixed plate 12.

[0026] In this embodiment, as Figures 1 to 4 As shown, the frame 10 has a sliding portion 14 that protrudes outward from the frame 10 and extends along the traveling direction of the massage mechanism 30. The massage mechanism 30 can abut against the sliding portion 14 and slide along the sliding portion 14, effectively reducing the frictional resistance between the massage mechanism 30 and the frame 10. The sliding portion 14 adopts a multiple parallel design, and each sliding portion 14 is arranged at intervals perpendicular to the moving direction of the massage mechanism 30. Correspondingly, the massage mechanism 30 has a groove 37 that mates with the sliding portion 14. The sliding portion 14 is located below the guide rail 20.

[0027] In this embodiment, as Figures 1 to 5 As shown, the guide rail 20 can be configured to extend along the user's body; the extension path of the guide rail 20 can be a curved segment or a straight segment. When the guide rail 20 uses a curved segment, the curvature of the guide rail 20 can correspond to the curve of the user's body to achieve a more fitting massage trajectory.

[0028] In this embodiment, as Figures 1 to 3 As shown, two fixed seats 22 are arranged between the frame 10 and the guide rail 20. The two fixed seats 22 are located at both ends of the guide rail 20 and are fixed to the frame 10. The fixed seats 22 are configured to support the guide rail 20 so that there is a certain distance between the guide rail 20 and the frame 10, so that there is a preset gap between the sliding section and the frame 10. The two ends of the guide rail 20 form a cantilever support structure with the frame 10 through the fixed seats 22. This support method ensures that the guide rail 20 extends stably along the walking direction, and the preset gap between the sliding section and the frame 10 is naturally formed by the assembly gap between the fixed seats 22 and the frame 10.

[0029] In this embodiment, as Figures 1 to 3As shown, the mounting base 22 includes two bases 221 spaced apart along the width of the guide rail 20, and the guide rail 20 is fixed to the bases 221 by fasteners. The mounting base 22 is integrally formed with the frame 10; specifically, the mounting base 22 is integrally formed with the fixing plate 12, which can enhance the structural strength of the mounting base 22 and the fixing plate 12, and reduce the processing difficulty of the mounting base 22 and the fixing plate 12. The fasteners can be bolts, so as to facilitate the assembly and disassembly of the guide rail 20 and the bases 221.

[0030] In this embodiment, as Figures 1 to 5 As shown, the massage mechanism 30 includes a housing 31, which has a groove 311. The guide rail 20 passes through the groove 311 so that the housing 31 is fitted on the outside of the guide rail 20. While ensuring that the massage mechanism 30 slides smoothly along the guide rail 20, the wall of the groove 311 can also constrain the guide rail 20 to prevent the massage mechanism 30 from separating from the guide rail 20.

[0031] In this embodiment, as Figures 1 to 5 As shown, the massage mechanism 30 includes a drive wheel 32 and an auxiliary wheel 321; there are two guide rails 20 arranged side by side, one of which has a rack segment 21 that meshes with the drive wheel 32, and the other guide rail 20 cooperates with the auxiliary wheel 321. The drive wheel 32 is a gear that can mesh with the rack segment 21 to enable the drive wheel 32 to move stably along the rack segment 21. The auxiliary wheel 321 cooperates with the guide rails 20 to ensure the stability of the massage mechanism 30 during operation.

[0032] In this embodiment, as Figures 1 to 5 As shown, the auxiliary wheel 321 is rotatably mounted on the housing 31 of the massage mechanism 30 and located within the slide groove 311; the auxiliary wheel 321 rolls in contact with the guide rail 20. The rotation axis of the auxiliary wheel 321 is perpendicular to the rotation axis of the drive wheel 32.

[0033] In this embodiment, as Figures 1 to 5 As shown, when both guide rails 20 are curved, the two guide rails 20 bend and deform in the same plane. By adjusting the spacing between the guide rails 20, a lateral bending shape is achieved, so that the guide rails 20 can be laterally bent along the width direction of the user's body. By adjusting the displacement range of the massage mechanism 30 in the horizontal direction, the massage coverage area and intensity distribution are optimized.

[0034] In this embodiment, as Figures 4 to 6As shown, the massage mechanism 30 also includes a first massage head 33 and a first motor 331. The first massage head 33 is configured to perform massage actions; the first motor 331 synchronously drives the first massage head 33 and the drive wheel 32 through a first transmission structure 332. The synchronous operation of the first massage head 33 and the drive wheel 32 by the first motor 331 can reduce the number of power sources and optimize the internal space layout of the massage mechanism 30.

[0035] In this embodiment, as Figure 6 As shown, the first transmission structure 332 includes a worm 3321, a worm wheel 3322, a first gear 3323, and a second gear 3324. The worm 3321 is fixed to the output shaft of the first motor 331; the worm wheel 3322 meshes with the worm 3321 for transmission; the first gear 3323 is coaxially fixed with the worm wheel 3322; the second gear 3324 is coaxially fixed with the drive wheel 32 and meshes with the first gear 3323 for transmission; the first massage head 33 is fixed to the worm wheel 3322, the first gear 3323, or the second gear 3324. When the first motor 331 starts, its output shaft drives the worm gear 3321 to rotate. The worm gear 3321 meshes with the worm wheel 3322, causing the worm wheel 3322 to rotate around a fixed axis. Since the first gear 3323 is coaxially fixed with the worm wheel 3322, the first gear 3323 and the worm wheel 3322 rotate synchronously. The first gear 3323 then drives the meshing second gear 3324 to rotate. The second gear 3324 is coaxially fixed with the drive wheel 32, thereby driving the drive wheel 32 to move along the rack segment 21 of the guide rail 20. At the same time, the first massage head 33, which is fixed to the worm wheel 3322, the first gear 3323, or the second gear 3324, synchronously performs a massage action, realizing the linkage control between the movement of the drive wheel 32 and the action of the first massage head 33. The first massage head 33 is fixed to the worm wheel 3322.

[0036] In this embodiment, as Figure 6 As shown, the first transmission structure 332 also includes a third gear 3325 and a fourth gear 3326. The third gear 3325 directly meshes with the first gear 3323, and the fourth gear 3326 is coaxially arranged with the third gear 3325 and directly meshes with the second gear 3324. The first gear 3323 drives the fourth gear 3326 through the third gear 3325, and the fourth gear 3326 drives the second gear 3324.

[0037] In this embodiment, as Figures 4 to 5 as well as Figures 7 to 10As shown, the massage device 100 also includes a second massage head 34 and a second motor 343. The second massage head 34 is configured to perform massage actions; the second motor 343 drives the second massage head 34 through a second transmission structure. The second transmission structure includes an eccentric member 344, which is disposed between the output shaft of the second motor 343 and the second massage head 34. The eccentric member 344 is configured to convert the rotational motion of the second motor 343 into the reciprocating motion of the second massage head 34, thereby achieving periodic axial impact of the second massage head 34. The controllability of the contact pressure, impact depth, and frequency when acting on the human body is significantly enhanced, thereby improving the targeted muscle relaxation effect. The first massage head 33 and the second massage head 34 are spaced apart along the walking direction of the massage mechanism 30; the first massage head 33 performs kneading actions, and the second massage head 34 performs tapping actions.

[0038] In this embodiment, as Figures 7 to 10 As shown, the massage mechanism 30 includes a base 35, which has a mounting cavity 351 and a constraint port 352. A second motor 343 is fixedly mounted to the movable base 35, and at least a portion of the second motor 343 is located within the mounting cavity 351. An eccentric member 344 is located within the mounting cavity 351. A portion of the second massage head 34 is located within the mounting cavity 351, and another portion is located outside the base 35 via the constraint port 352. The constraint port 352 restricts the second massage head 34 from rotating with the eccentric member 344, thereby converting the rotational motion of the motor into the reciprocating motion of the second massage head 34.

[0039] In this embodiment, as Figures 7 to 10 As shown, the structure of base 35 is not strictly limited; for example, base 35 can be a housing 31 structure. The constraint opening 352 is located at the top of base 35 (on the side of base 35 facing away from frame 10). An eccentric member 344 is fixed to the motor shaft of the motor and is eccentrically positioned with respect to the output shaft of the second motor 343, so that the second motor 343 drives the eccentric member 344 to move eccentrically. The eccentric member 344 is an eccentric wheel.

[0040] In this embodiment, as Figures 7 to 10 As shown, the second massage head 34 includes a connecting arm 341 and a massage head 342. One end of the connecting arm 341 is pivotally connected to the eccentric member 344, and the other end is located outside the base 35 and fixedly connected to the massage head 342. The eccentric member 344 drives the massage head through the connecting arm 341, so that the massage head 342 performs a massage action on the user. The connecting arm 341 has a pivot hole, at least a portion of the eccentric member 344 is located in the pivot hole and rotatably connected to the pivot hole. The extending direction of the connecting arm 341 is substantially perpendicular to the rotation axis of the eccentric member 344.

[0041] In this embodiment, as Figures 7 to 10As shown, the massage mechanism 30 also includes a drive shaft 36, which is rotatable about a predetermined axis. The drive shaft 36 is configured to drive the base 35 to move along the axial direction of the drive shaft 36 during rotation. When it is necessary to adjust the position of the second massage head 34, the drive shaft 36 rotates, driving the base 35 to move, thereby moving the second massage head 34.

[0042] In this embodiment, as Figures 7 to 10 As shown, the drive shaft 36 is provided with an external thread, and the base 35 is provided with a threaded hole 353 that mates with the external thread, so that the base 35 can move axially along the drive shaft 36 during the rotation of the drive shaft. The massage mechanism 30 also includes a third motor 361, a first worm gear 3322, and a first worm 362. The first worm 362 is fixed to the output shaft of the third motor 361; the first worm gear 3322 is fixed to the drive shaft 36, and the first worm gear 3322 meshes with the first worm 362 for transmission. When the third motor 361 starts, the output shaft drives the first worm 362 to rotate, and the first worm gear 362 meshes with the first worm gear 3322 to drive the first worm gear 3322 to rotate, thereby driving the drive shaft 36 to rotate.

[0043] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
