Description

Technical Field

[0001] This application relates to the field of healthcare equipment technology, and in particular to a dynamic soothing device. Background Technology

[0002] With increasing health awareness and a faster pace of life, muscle fatigue relief and rehabilitation equipment is gradually entering homes and professional health and wellness settings. Among them, dynamic relaxation devices for limbs such as legs and arms are widely used because they can simulate kneading and stroking techniques to promote blood circulation and relieve muscle soreness.

[0003] Most existing dynamic relaxation devices use rigid tracks to guide the casing. The casing maintains a fixed posture and height during movement. When the device moves to a thicker part of the limb, the two massage heads are pushed outward by the limb, which generates a large interaction force between the casing and the track. This causes the user to clearly feel the device's rigid clamping force, which can cause pain and discomfort in severe cases, affecting the user experience. Summary of the Invention

[0004] This application provides a dynamic relief device to at least solve the problem of pain and discomfort caused by the rigid clamping of existing devices when they are moved to different parts of the limb.

[0005] To achieve the above objectives, this application adopts the following technical solution: According to one aspect of this application, a dynamic soothing device is provided, comprising: seat body; The housing is movably mounted on the base. The traveling mechanism includes two traveling racks spaced apart. The ends of the traveling racks are mounted on the base. Traveling gears mesh on the traveling racks. The middle part of the traveling racks is suspended. A traveling driver is mounted on the housing. A worm is mounted on the rotating end of the traveling driver. Helical teeth mesh on opposite sides of the worm. The two helical teeth are used to drive the two traveling gears to rotate. The soothing mechanism includes a swing frame rotatably mounted on the housing, the swing frame being provided with vibrating contacts, and the soothing mechanism having two sets spaced apart. Two sets of positioning mechanisms are respectively disposed on both sides of the housing, connecting the housing and the corresponding traveling racks, and the housing is suspended between the two traveling racks through the positioning mechanisms; When the two vibrating contacts swing away from each other, the rotation of the swing frame presses down on the housing and acts on the traveling rack through the positioning mechanism, causing the traveling rack to undergo elastic bending deformation to ensure that the vibrating contacts are opened. The elastic bending deformation of the traveling rack causes its local tooth surface to tilt, which cooperates with the traveling gear that moves synchronously with the housing to adaptively adjust the meshing angle with the traveling gear.

[0006] In one embodiment, the vibrating contact includes a connecting rod and a vibration damping element; One end of each of the two connecting rods is respectively disposed on the two swing frames, and the other ends of the two connecting rods extend inclinedly in a direction away from each other; The vibration damping component is sleeved on the connecting rod and is movably arranged along the axial direction of the connecting rod. A first reset component is provided between the vibration damping component and the connecting rod, and the first reset component is used to reset the vibration damping component.

[0007] In one embodiment, the vibration damping component has a guide hole, the connecting rod is inserted into the guide hole, the end of the connecting rod is provided with a limiting component, and the first resetting component is disposed in the guide hole and connects the vibration damping component and the limiting component.

[0008] In one embodiment, the positioning mechanism includes a groove and a slider that are fitted together, one of which is disposed on the housing and the other is disposed on the traveling rack.

[0009] In one embodiment, mounting slots are provided on both opposite sides of the housing, and the two traveling racks are respectively inserted into the two mounting slots. The top and bottom surfaces of the traveling racks are provided with sliding grooves, and each slider is disposed in the corresponding mounting slot to clamp the traveling rack in the mounting slot. When the traveling rack undergoes elastic bending deformation, the slide groove bends synchronously with the traveling rack. The slider slides within the bent slide groove and is guided by a guiding force. The guiding force causes the housing to adjust its posture in accordance with the deformation of the traveling rack, so as to maintain the sliding fit between the slider and the slide groove.

[0010] In one embodiment, the helical gear is connected to the corresponding traveling gear via a transmission assembly comprising at least two meshing gear pairs to absorb displacement of the traveling gear caused by the deflection of the housing.

[0011] In one embodiment, the transmission assembly includes a first pinion coaxially fixed to the helical gear, a first large gear meshing with the first pinion, a second pinion coaxially fixed to the first large gear, and the second pinion meshing with the corresponding traveling gear.

[0012] In one embodiment, the soothing mechanism further includes a soothing actuator and a driving member. The driving member is disposed at the rotating end of the soothing actuator and has at least one actuating part offset from its rotation center. Both swing frames are located on the rotation path of the actuating part to drive the swing frames to swing through the actuating part. A second resetting member is disposed between the swing frame and the housing for resetting the swing frame.

[0013] In one embodiment, two symmetrically arranged action parts are provided, and the two action parts periodically abut against the two swing frames respectively, driving the two swing frames to swing synchronously in opposite directions.

[0014] In one embodiment, a support contact is rotatably disposed on the housing, the support contact being located between two vibrating contacts and forming a triangular support with the two vibrating contacts.

[0015] According to an embodiment of this application, a dynamic relaxation device is provided in which, when the housing moves to a thicker part of the limb, two vibrating contacts are pushed outward by the limb. The pushing force is transmitted to the housing through the swing frame, causing the housing to press down on the traveling rack. Since the middle of the traveling rack is suspended, it will undergo downward elastic deformation under pressure, thereby enabling the device to adapt to changes in the limb contour, avoiding the discomfort caused by hard clamping and improving user comfort.

[0022] Reference Figures 1-9 As shown, this embodiment provides a dynamic relief device, including a seat 1, a housing 2, a traveling mechanism 3, a relief mechanism 4, and two sets of positioning mechanisms 5.

[0023] The housing 2 is movably mounted on the base 1.

[0024] The traveling mechanism 3 includes a traveling rack 31, two of which are spaced apart. The ends of the traveling racks 31 are mounted on the base 1. Traveling gears 32 mesh on the traveling racks 31. The middle part of the traveling racks 31 is suspended. A traveling driver 33 is mounted on the housing 2. A worm gear 34 is mounted on the rotating end of the traveling driver 33. Helical teeth 35 mesh on opposite sides of the worm gear 34. The two helical teeth 35 are used to drive the two traveling gears 32 to rotate.

[0025] The soothing mechanism 4 includes a swing frame 41 rotatably mounted on the housing 2. The swing frame 41 is equipped with vibrating contacts 42. Two sets of these vibrating contacts 42 are spaced apart, with each pair positioned on opposite sides of the limb. The soothing mechanism 4 is used to massage and soothe the limb, with the two pairs of vibrating contacts 42 positioned on opposite sides of the limb to hold and massage it from both sides.

[0026] Two sets of positioning mechanisms 5 are respectively disposed on both sides of the housing 2, connecting the housing 2 and the corresponding traveling racks 31. The housing 2 is suspended between the two traveling racks 31 by the positioning mechanisms 5, thereby guiding and supporting the movement of the housing 2.

[0027] In use, place the device near the limb, with the two vibrating contacts 42 positioned on opposite sides of the limb. The traveling driver 33 drives the helical gears 35 on both sides to rotate synchronously via the worm gear 34, which in turn drives the two traveling gears 32 to rotate synchronously. Guided by the traveling rack 31, the driving housing 2 reciprocates along the length of the traveling rack 31.

[0028] Both ends of the traveling rack 31 are mounted on the base 1. The two ends of the traveling rack 31 can be connected to the base 1 by means such as plugging or welding. There is no support structure between the middle part of the traveling rack 31 and the base 1. That is to say, there is a gap between the middle part of the traveling rack 31 and the base 1 in the circumferential direction. The traveling rack 31 is only constrained at both ends in its length direction, and the middle part can move freely relative to the base 1.

[0029] When the two vibrating contacts 42 swing to the side away from each other, the rotation of the swing frame 41 presses down on the housing 2 and acts on the traveling rack 31 through the positioning mechanism 5, causing the traveling rack 31 to undergo elastic bending deformation, so as to ensure that the vibrating contacts 42 are opened, thus solving the problem of hard clamping caused by existing devices when moving to different parts of the limb, which causes pain and discomfort to the user during use.

[0030] The elastic bending deformation of the traveling rack 31 causes its local tooth surface to tilt, which cooperates with the traveling gear 32 that moves synchronously with the housing 2 to adaptively adjust the meshing angle with the traveling gear 32, thereby ensuring the stability of the movement of the housing 2 and avoiding movement jamming.

[0031] Combination Figure 3 Taking the use of this device for leg massage as an example, when in use, the device is placed on the leg. When the housing 2 moves to the thicker part of the leg, the two vibrating contacts 42 are pushed outward by the leg. The pushing force causes the two swing frames 41 to swing outward, which is transmitted to the housing 2, causing the housing 2 to be subjected to a downward pressure. The housing 2 is connected to the traveling rack 31 through the traveling gear 32 and is set on the traveling rack 31 through the positioning mechanism 5. Therefore, the downward pressure on the housing 2 is applied to the traveling rack 31 through the positioning mechanism 5. Since the middle part of the traveling rack 31 can move freely relative to the seat 1, the downward pressure cannot be canceled out, causing the middle part of the traveling rack 31 to undergo elastic bending deformation, and the traveling rack 31 is concave away from the leg. The elastic bending deformation of the traveling rack 31 simultaneously causes the connection between it and the housing 2 to move, thereby realizing the position change of the housing 2 when under pressure, ensuring that the two vibrating contacts 42 can be stably pushed outward and avoiding rigid clamping.

[0032] Simultaneously, the positional change of the housing 2 under pressure synchronously drives the positional change of the traveling gear 32 located on it. The elastic bending deformation of the traveling rack 31 under the downward pressure transmitted by the housing 2 causes its local tooth surface to tilt. The displacement of the traveling gear 32 and the tilting of the tooth surface of the traveling rack 31 cooperate with each other, ensuring that the two maintain a stable meshing effect under different deformation states. This adaptively adjusts the meshing angle between the traveling gear 32 and the traveling rack 31, avoiding poor meshing or jamming caused by the positional change of the traveling gear 32, ensuring the smoothness and reliability of power transmission, and ensuring the stable movement of the housing 2.

[0033] Combination Figure 4 When the housing 2 moves to the narrower part of the leg, the spreading force on the two vibrating contacts 42 decreases, and the pressure transmitted to the housing 2 through the swing frame 41 decreases accordingly. The traveling rack 31 recovers its deformation under its own elasticity, driving the housing 2 to move closer to the leg and reset, so that the two vibrating contacts 42 move back to the middle and maintain close contact with the leg.

[0034] Thus, the elastic deformation of the traveling rack 31 allows the housing 2 to automatically adjust its distance from the leg according to changes in leg thickness. When moving to a position where the leg is thicker, the housing automatically moves down away from the leg to release the clamping force; when moving to a position where the leg is thinner, the housing 2 automatically moves up closer to the leg to maintain contact. The self-adaptive adjustment of the relative position of the housing 2 by the suspended middle of the traveling rack 31 ensures that the two vibrating contacts 42 always maintain an appropriate clamping force against the leg, solving the problem of rigid clamping pain caused by the inability of traditional devices to automatically adjust the clamping force according to changes in limb contour.

[0035] In this embodiment, the worm gear 34 and helical gear 35 drive the rotation of the travel gear 32, ensuring stable movement of the housing 2. When targeted massage is needed, the travel driver 33 stops working. Due to the self-locking characteristics of the worm gear 34 and helical gear 35, the travel gear 32 cannot drive the worm gear 34 to rotate in the opposite direction, and the housing 2 is locked in the current position, ensuring the stability and reliability of the housing 2's fixed position. Compared to the traditional lead screw drive method, where the two ends of the lead screw are used to connect two travel gears 32 to drive rotation, the lead screw design makes it difficult for the housing 2 to deform downwards under force, thus failing to achieve self-adaptation of the limb contour and failing to meet the user's comfort experience.

[0036] Reference Figures 1-9As shown, in some embodiments, the vibration contact 42 includes a connecting rod 421 and a vibration damping element 422. One end of each of the two connecting rods 421 is respectively disposed on one of the two swing frames 41, and the other ends of the two connecting rods 421 extend obliquely in a direction away from each other. The vibration damping element 422 is sleeved on the connecting rod 421 and is movably disposed along the axial direction of the connecting rod 421. A first reset element 43 is provided between the vibration damping element 422 and the connecting rod 421, and the first reset element 43 is used to reset the vibration damping element 422. The two vibration damping elements 422 are clamped on both sides of the limb. By the oblique arrangement of the connecting rod 421, the lateral distance between the two vibration contacts 42 can be adjusted when the vibration contact 42 moves on the connecting rod 421, thereby adapting to parts of the limb with different circumferences.

[0037] When the first reset member 43 is in its normal state, the vibration damping member 422 is located on the side of the connecting rod 421 near the swing frame 41. When the housing 2 moves to a thicker part of the limb, the vibration damping member 422 slides along the connecting rod 421 away from the swing frame 41, stretching the first reset member 43; when the housing 2 moves to a thinner part of the limb, the first reset member 43 pulls the vibration damping member 422 away from the swing frame 41, ensuring that the vibration damping member 422 is always in contact with the skin, achieving adaptive fit. This allows it to adapt to different limb circumferences of users, as well as to variations in thickness of different parts of the same limb, solving the problem of traditional fixed-pitch contacts being suspended in thinner parts of the limb and causing pain in thicker parts of the limb. For example, the two vibration contacts 42 can provide soothing stimulation to both the arm and the leg; furthermore, when the two vibration contacts 42 are used to soothe the leg, the movement of the two vibration damping members 422 can also adapt to users with different leg circumferences.

[0038] In addition, when the vibration damping member 422 moves along the connecting rod 421, it stretches the first reset member 43. The first reset member 43 can also absorb some of the impact energy, making the force transmitted to the swing frame 41 and the housing 2 smoother, thereby further improving the comfort of use, while also ensuring the meshing stability between the traveling gear 32 and the traveling rack 31.

[0039] The first reset component 43 includes a spring, a disc spring, or elastic rubber, etc. In this embodiment, the first reset component 43 is a spring.

[0040] Combination Figure 10Optionally, the vibration damping component 422 has a guide hole 4221, the connecting rod 421 is inserted into the guide hole 4221, and the end of the connecting rod 421 is provided with a limiting member 44. The first reset member 43 is disposed in the guide hole 4221 and connects the vibration damping component 422 and the limiting member 44. The guide hole 4221 is opened inside the vibration damping component 422 to provide installation and sliding space for the connecting rod 421. The connecting rod 421 is inserted into the guide hole 4221, and the limiting member 44 is fixed to the end of the connecting rod 421 to limit the movement range of the vibration damping component 422 and prevent the vibration damping component 422 from falling off the connecting rod 421. The first reset member 43 is disposed inside the guide hole 4221, arranged around the connecting rod 421, with one end connected to the vibration damping component 422 and the other end connected to the limiting member 44. Therefore, the first reset member 43 is built into the vibration damping member 422 to ensure the reliability of the reciprocating movement of the vibration damping member 422, while improving the overall aesthetics of the device.

[0041] The limiting member 44 is detachably connected to the connecting rod 421. The limiting member 44 can be a baffle or a retaining ring, etc., and can be detachably set on the connecting rod 421 by means of bolts or buckles, so as to block the end of the guide hole 4221 and ensure the stable connection between the connecting rod 421 and the vibration damping member 422.

[0042] In this embodiment, a slot 4211 is provided on the outer wall surface of the connecting rod 421, and the limiting member 44, which is a retaining spring or a retainer, is engaged in the slot 4211, thereby realizing the connection between the limiting member 44 and the connecting rod 421. This facilitates the installation, disassembly and replacement of the limiting member 44, reduces costs and improves assembly efficiency.

[0043] The vibration damping component 422 has an annular groove 4222 at its end away from the swing frame 41. The inner diameter of the annular groove 4222 is larger than the outer diameter of the guide hole 4221. The annular groove 4222 and the guide hole 4221 are coaxially arranged. The first reset component 43 is disposed within the annular groove 4222. Thus, by placing the first reset component 43 within the annular groove 4222 and the connecting rod 421 within the guide hole 4221, the assembly positions of the various components are separated, ensuring independent operation of each component and preventing interference and movement jamming. Furthermore, by placing the first reset component 43 within the annular groove 4222, the bottom of the groove 4222 directly restricts the movement of the reset component. Connection is achieved through the contact and engagement of the two components, facilitating assembly.

[0044] The connecting rod 421 is inserted into the guide hole 4221, and the outer wall of the connecting rod 421 contacts and engages with the inner wall of the guide hole 4221. This surface contact engagement reduces sliding friction resistance, improves the guiding effect, ensures the straightness of the reciprocating movement of the vibration damping component 422, and guarantees the massage position and massage effect.

[0045] Combination Figure 11 In some embodiments, the guide hole 4221 is formed through the vibration damping component 422. The inlet end of the guide hole 4221 mates with the connecting rod 421, and the outlet end of the guide hole 4221 is provided with a plug 423. The plug 423 is detachably connected to the vibration damping component 422 to seal the outlet end. By forming the guide hole 4221 through the entire component, the machining difficulty of the guide hole 4221 is reduced, and chip removal and cleaning are facilitated. During assembly, the connecting rod 421 is inserted from the inlet end. After the first reset member 43 is placed in the annular groove 4222, the limiting member 44 is assembled on the connecting rod 421. The limiting member 44 connects the connecting rod 421 to the vibration damping member 422, and also limits the first reset member 43 in the annular groove 4222 between the vibration damping member 422 and the limiting member 44. Then, the outlet end is sealed by the plug 423. This can improve the aesthetics of the vibration damping member 422 and also protect the first reset member 43 and the limiting member 44 inside the vibration damping member 422.

[0046] Optionally, the plug 423 has a clearance groove 4231 on the side facing the connecting rod 421. The clearance groove 4231 is used to avoid the second assembly end of the connecting rod 421 or the limiting member 44. In this way, when the distance between the vibration damping member 422 and the swing frame 41 is the farthest, interference between the plug 423 and the connecting rod 421 can be effectively avoided. This ensures the compactness of the overall structure while maximizing the travel of the vibration damping member 422. At the same time, it can also prevent the connecting rod 421 from colliding with the plug 423, ensuring the service life of each component, avoiding noise caused by collision, and ensuring the user experience.

[0047] The detachable connection between the plug 423 and the vibration damping component 422 includes threaded connection or snap-fit ​​connection, etc., which is not limited in this embodiment.

[0048] In some embodiments, the vibrating contact 42 further includes a positioning component 424, which includes a positioning protrusion 4241 and a positioning groove 4242 that are fitted together. One of the positioning protrusion 4241 and the positioning groove 4242 is disposed on the vibration damping member 422, and the other is disposed on the plug 423. By embedding the positioning protrusion 4241 in the positioning groove 4242, the plug 423 is positioned and installed, which not only ensures the installation position of the plug 423, but also improves assembly efficiency. In this embodiment, the positioning groove 4242 is disposed on the vibration damping member 422, and the positioning protrusion 4241 is disposed on the plug 423.

[0049] In some embodiments, the positioning mechanism 5 includes a groove 51 and a slider 52 that are fitted together. One of the groove 51 and the slider 52 is disposed on the housing 2, and the other is disposed on the traveling rack 31. The cooperation of the groove 51 and the slider 52 achieves connection and guidance between the housing 2 and the traveling rack 31, preventing the housing 2 from detaching from the traveling rack 31 and ensuring the safety and reliability of the structure. Of course, the positioning mechanism 5 may also include, for example, a sliding rail and a groove that cooperate with each other, wherein the sliding rail is disposed on the traveling rack 31, and the groove is formed on the housing 2.

[0050] The slide groove 51 and the slider 52 have matching cross-sectional shapes, including trapezoidal, T-shaped or rectangular shapes, to prevent the slider 52 from coming out of the slide groove 51.

[0051] In this embodiment, a groove 51 is formed on the traveling rack 31, and a slider 52 is disposed on the housing 2. When the traveling gear 32 rotates and drives the housing 2 to move along the traveling rack 31, the slider 52 slides synchronously within the groove 51. The groove 51 constrains the movement direction of the slider 52, causing the housing 2 to move along the extension direction of the groove 51, thereby improving the reliability of the movement of the housing 2 and avoiding swaying and shaking during the movement.

[0052] When the housing 2 moves to the thicker part of the limb, the two vibrating contacts 42 are pushed outward by the limb. This pushing force is transmitted to the housing 2 through the swing frame 41, causing the housing 2 to be subjected to downward pressure. Since the housing 2 is embedded in the groove 51 of the traveling rack 31 through the slider 52, the pressure is transmitted to the bottom surface 312 of the groove 51 through the slider 52, causing the traveling rack 31 to be subjected to a downward force at the position where it contacts the slider 52. The two ends of the traveling rack 31 are fixed to the base 1, and the middle is suspended, thus undergoing elastic deformation. After the traveling rack 31 bends downward, since the groove 51 is opened on the traveling rack 31, the groove 51 bends downward synchronously with the traveling rack 31. When the slider 52 embedded in the slide groove 51 slides within the downwardly curved slide groove 51, it is guided by the side wall of the slide groove 51 and transmitted to the housing 2 through the slider 52. This causes the housing 2 to move downward as a whole while generating an attitude change that adapts to the bending direction of the slide groove 51. This ensures the stability and reliability of the relative movement between the housing 2 and the traveling rack 31, avoids jamming caused by the deformation of the traveling rack 31, and ensures the smoothness of the movement of the housing 2.

[0053] The groove 51 can be formed at any position of the traveling rack 31, such as the top surface 311, bottom surface 312, the side of the two traveling racks 31 facing each other, or the side of the two traveling racks 31 moving away from each other.

[0054] Reference Figures 1-5 Optionally, mounting grooves 21 are provided on both opposite sides of the housing 2. Two traveling racks 31 are respectively inserted into the two mounting grooves 21. Sliding grooves 51 are provided on the top surface 311 and bottom surface 312 of each traveling rack 31. Each slider 52 is disposed in its corresponding mounting groove 21 to clamp the traveling rack 31 within the mounting groove 21. When the traveling rack 31 undergoes elastic deformation under the pressure of the housing 2 to adjust its meshing angle with the traveling gear 32, the sliding groove 51 bends synchronously with the traveling rack 31. The slider 52 slides within the bent sliding groove 51 and is guided by a force. This guiding force causes the housing 2 to adjust its posture in accordance with the deformation of the traveling rack 31, thereby maintaining the sliding engagement between the slider 52 and the sliding groove 51.

[0055] The opening of the mounting slot 21 faces the outside of the housing 2. The traveling rack 31 is inserted into the mounting slot 21, with its top surface 311 facing the top wall of the mounting slot 21 and its bottom surface 312 facing the bottom wall of the mounting slot 21. A sliding groove 51 is formed on the top surface 311 and bottom surface 312 of the traveling rack 31, extending through or not through the length. A slider 52 is fixedly mounted on the top and bottom walls of the mounting slot 21, protruding into the mounting slot 21 and embedded in the sliding grooves 51 on the top surface 311 and bottom surface 312 of the traveling rack 31. The upper and lower sliders 52 work together to clamp the traveling rack 31 in the mounting slot 21, allowing the housing 2 to be suspended from the traveling rack 31 by the sliders 52.

[0056] Combination Figure 6 When the traveling gear 32 rotates and drives the housing 2 to move along the traveling rack 31, the slider 52 on the housing 2 slides synchronously within the groove 51 of the traveling rack 31. The upper slider 52 slides within the groove 51 on the top surface 311, and the lower slider 52 slides within the groove 51 on the bottom surface 312, together guiding and constraining the movement of the housing 2. This further prevents the housing 2 from falling off the traveling rack 31 during movement, improving the safety and reliability of the device, and ensuring the straightness and stability of the movement.

[0057] When the traveling rack 31 undergoes elastic deformation, the grooves 51 on the top surface 311 and bottom surface 312 bend synchronously with the traveling rack 31, since the grooves 51 are formed on the traveling rack 31. The upper and lower sets of sliders 52, embedded in the grooves 51, slide within the curved grooves 51 and are guided by the sidewalls of the grooves 51. Since both sets of sliders 52 are fixed in the same mounting slot 21 of the housing 2, the two sliders 52 move simultaneously along the bending direction of the grooves 51, causing the housing 2 to adjust its posture in the same direction as the bending of the traveling rack 31. This adapts the posture of the housing 2 to the bending profile of the traveling rack 31, preventing the sliders 52 from jamming with the grooves 51 due to rack deformation and ensuring smooth movement. In addition, by clamping from both the top and bottom, the housing 2 can only change its posture as a whole when the traveling rack 31 deforms, and will not swing about a certain point as a fulcrum. This avoids the shaking that the housing 2 may cause during walking, ensures the stable and reliable contact of the vibrating contact head 42 with the limb, and guarantees the massage effect.

[0058] Reference Figures 1-7 In some embodiments, the helical gear 35 is connected to the corresponding traveling gear 32 via a transmission assembly comprising at least two meshing gear pairs to absorb the displacement of the traveling gear 32 caused by the deflection of the housing 2. The gears of each gear pair mesh sequentially, forming a power transmission path from the helical gear 35 to the traveling gear 32. The number of teeth in each gear pair can be selected as needed to achieve an appropriate reduction ratio.

[0059] When the housing 2 moves downward and changes its posture due to force, the traveling gear 32 mounted on the housing 2 will also move accordingly, and the displacement will be transmitted step by step to the helical gear 35 through the gear pairs. Due to the tooth backlash and meshing elasticity between the gear pairs, the displacement of the traveling gear 32 will be absorbed and attenuated step by step, thereby ensuring the precise meshing of the helical gear 35 and the worm 34, avoiding tooth surface point contact, edge contact or jamming caused by displacement, and ensuring the smoothness and self-locking reliability of the helical gear 35 and worm 34 transmission.

[0060] The transmission assembly includes a first pinion 36 coaxially fixed to the helical gear 35, a first large gear 37 meshing with the first pinion 36, and a second pinion 38 coaxially fixed to the first large gear 37. The second pinion 38 meshes with the corresponding traveling gear 32. This two-stage meshing—the first pinion 36 driving the first large gear 37, and the second pinion 38 driving the traveling gear 32—enables the traveling gear 32 to obtain a larger torque output, ensuring that the housing 2 can still move smoothly under massage reaction force and avoiding jamming due to insufficient driving force.

[0061] Therefore, by driving the rotation of two sets of gears through a single drive driver 33, the housing 2 reciprocates between two sets of parallel drive racks, avoiding the problem of asynchronous movement caused by multiple drives driving the housing 2, as well as the problem of motion load of a single motor and single rail. This effectively ensures motion stability and massage comfort while reducing wear on the gear sets and extending the product's service life.

[0062] Reference Figures 1-8 In some embodiments, the soothing mechanism 4 further includes a soothing actuator 45 and a driving member 46. The driving member 46 is disposed at the rotating end of the soothing actuator 45. The driving member 46 has an action part 461 offset from its rotation center. Both swing frames 41 are located on the rotation path of the action part 461 so as to drive the swing frame 41 to swing through the action part 461. A second reset member 47 is disposed between the swing frame 41 and the housing 2. The second reset member 47 is used to provide a reset force for the swing frame 41.

[0063] The second reset member 47 includes a spring, a disc spring, or elastic rubber, etc. In this embodiment, the second reset member 47 is a spring.

[0064] The soothing actuator 45 causes the drive member 46 to rotate, and the action part 461 rotates synchronously. During the rotation, the action part 461 periodically abuts against the two swing frames 41. When the action part 461 rotates to contact the swing frame 41, it pushes the swing frame 41 to swing. The second reset member 47 is stretched or compressed. As the action part 461 rotates to disengage from the swing frame 41, the reset force of the second reset member 47 pulls or pushes the swing frame 41 to reset, thereby realizing the reciprocating swing of the swing frame 41.

[0065] Vibrating contacts 42 are mounted on the swing frame 41, allowing the two vibrating contacts 42 to continuously knead and massage the limbs. By adjusting the rotation speed of the soothing driver 45, the contact frequency between the actuating part 461 and the swing frame 41 can be adjusted, thereby regulating the swing frequency of the swing frame 41 and the massage rhythm to meet the personalized needs of different users.

[0066] In some embodiments, the swing frame 41 is rotatably provided with a rotating wheel 48 at the contact point with the action part 461. The rotation axis of the rotating wheel 48 is parallel to the rotation axis of the drive member 46, which transforms the sliding friction between the action part 461 and the swing frame 41 into rolling friction, reducing frictional resistance and wear during the movement process, making the device operate more smoothly, and also extending the service life of the action part 461 and the swing frame 41.

[0067] Of course, the end face of the swing frame 41 that cooperates with the action part 461 can also be set as a smooth arc surface to reduce the impact force when the action part 461 contacts the swing frame 41, and avoid damage to the action part 461 and the swing frame 41 due to contact with sharp corners.

[0068] In some embodiments, two symmetrically arranged action parts 461 are provided, and the two action parts 461 periodically abut against the two swing frames 41 respectively, driving the two swing frames 41 to swing synchronously in opposite directions, ensuring the symmetry of the soothing stimulation and improving the soothing stimulation effect.

[0069] In addition, by periodically squeezing and relaxing the limbs, a regular soothing stimulation frequency is formed. The soothing stimulation force is transmitted to the housing 2 through the swing frame 41, and then to the traveling rack 31, causing the traveling rack 31 to produce elastic deformation fluctuations synchronized with the soothing stimulation frequency.

[0070] Elastic deformation fluctuations are transmitted to the slider 52 through the slide groove 51, which in turn causes the housing 2 and the traveling gear 32 to produce periodic displacements synchronized with the frequency of soothing stimulation, resulting in a periodic change in the meshing clearance between the traveling gear 32 and the traveling rack 31. When the meshing clearance between the traveling gear 32 and the traveling rack 31 increases, any tiny debris that may be present between the meshing surfaces, such as dust and debris, will be loosened or discharged, achieving automatic cleaning and preventing movement jamming caused by debris.

[0071] In addition, compared to the noise generated at a specific frequency by gear meshing with a fixed clearance, the periodically changing meshing clearance can reduce noise and improve the user experience.

[0072] Reference Figures 1-5 In some embodiments, a support contact 6 is rotatably mounted on the housing 2. The support contact 6 is located between the two vibrating contacts 42 and forms a triangular support with the two vibrating contacts 42, thereby achieving multi-dimensional soothing stimulation of the limbs. Furthermore, by positioning the support contact 6 in the middle, it bears part of the limb pressure, making the force on the two vibrating contacts 42 more balanced. When the pressure on both sides of the vibrating contacts 42 is balanced, the downward pressure transmitted to the housing 2 through the swing frame 41 is also more symmetrical, thereby balancing the downward pressure on the two traveling racks 31. The elastic deformation of the two traveling racks 31 becomes more symmetrical and stable, thus ensuring the stable change of the housing 2's posture and avoiding swaying caused by excessive pressure on one side.

[0073] In addition, when the pressure of the two vibrating contacts 42 is uneven, the support contact 6 can provide a reverse torque to prevent the housing 2 from twisting, ensuring the stability and controllability of the attitude change of the housing 2, thereby ensuring the stable meshing of the traveling gear 32 and the traveling rack 31, and ensuring the reliability of the movement of the housing 2.

[0074] Among them, the support contact 6 will produce a continuous rolling massage effect on the limb during the follow-up process, forming a compound soothing stimulation mode of kneading on both sides and rolling in the middle with the kneading massage of the vibrating contacts 42 on both sides, which enhances the user experience.

[0075] In addition, the three-point support structure makes it easier to position the device on the limbs. When wearing it, the user only needs to place the limbs between the triangles formed, and the device will automatically center itself without the need for precise position adjustments.

[0076] Of course, the support contact 6 can also be mounted on the housing 2 via a swing frame 41. In this case, the support contact 6 is rotatably mounted on the swing frame 41, which is also located on the rotation path of the actuating part 461 and is connected to the housing 2 by a second reset member 47. This allows the support contact 6 to perform both rotational massage and vibration massage, enriching the device's soothing stimulation modes.

[0077] Reference Figures 1-11In summary, the dynamic relief device provided in this embodiment, by suspending the middle of the traveling rack 31, allows it to undergo downward elastic deformation when the housing 2 is pressed down. When the device moves to a thicker part of the limb, the vibrating contact 42 is opened, and the opening force is transmitted to the housing 2 through the swing frame 41, causing the housing 2 to press down on the traveling rack 31. The traveling rack 31 then undergoes a bending deformation that adapts to the contour of the limb, thereby adaptively adjusting the overall height and posture of the device. This avoids the problem of hard clamping pain caused by rigid structures and improves user comfort.

[0078] It should be noted that the dynamic soothing device provided in this embodiment can be applied to any part of the body to achieve soothing stimulation. For example, the dynamic soothing device can be applied to areas such as the legs, arms, or back.
