Description

Technical Field

[0001] This invention relates to the field of assistive devices, specifically a device for relieving wrist pain. Background Technology

[0002] Currently, most hand massage devices on the market use electric rollers, balls, silicone pads, or airbag inflation to massage the palms or backs of the hands, suitable for overall hand relaxation and promoting blood circulation. However, these devices generally lack specialized designs for the wrist, especially in terms of the fit of the massage structure, pressure adjustment capabilities, and ergonomic comfort.

[0003] In existing technologies, wrist massage modules mostly use rigid robotic arms with fixed angles or low-flexibility silicone heads. This design cannot dynamically adjust according to the actual differences in the user's wrist structure, which can easily cause local pressure, friction discomfort, or even secondary injury to areas with thin subcutaneous tissue or bony protrusions. In addition, the contact points of ordinary massage feel stiff and lack a biomimetic flexible transition structure, resulting in a rigid massage experience that cannot meet the needs of rehabilitation patients for high comfort and massage.

[0004] However, there is an urgent need in the existing technology for a solution to relieve wrist pain that can improve the fit and safety of wrist massage. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention aims to provide a device that can improve the fit and safety of wrist massage, significantly improve the user's comfort experience and pain relief effect during the massage process, and address the problems of poor structural adaptability, stiff touch of the massage area, lack of effective cushioning and biomimetic characteristics for sensitive areas such as the wrist in existing hand massage devices.

[0006] Specifically, the present invention solves the above-mentioned technical problems through the following technical solutions: According to one aspect of the present invention, a device for relieving wrist pain is provided, comprising a housing, wherein the housing has a front port for inserting into the wrist and a rear port for placing the palm on both sides, the front port and the rear port being in communication with each other. Multiple upper massage components are arranged in a ring array at the top of the inner cavity of the outer shell near the front port. The central angle of the ring array is less than 50 degrees. The upper massage components include a soft composite pressure-relieving massage unit that contacts the wrist. The upper massage component is mounted on a softly adjustable extension portion, which is located within the inner cavity of the outer shell. A wrist rest assembly is provided, located below the upper massage assembly and within the inner cavity of the housing.

[0007] In this invention, the wrist is placed on the placement component, and the upper massage component, which can be pushed outward, contacts the outer or inner part of the wrist to massage the wrist. The end that contacts the wrist is a soft composite pressure-relieving massage unit. By using the composite pressure-relieving massage unit to mimic the fingertips of human fingers to massage the wrist, the problem of ordinary massage equipment having an overly hard contact point with the wrist can be avoided. This adapts to the fact that the wrist is generally not under pressure, giving the user a better massage experience and improving the pain relief effect.

[0008] Furthermore, in this technical solution, the composite pressure-relieving massage unit includes a support frame, which is fixed to the drive unit. The drive unit is disposed on the bearing unit, which is disposed on the soft ejector part that drives its movement. The surface of the support frame is covered with a buffer bladder, and a deformable buffer layer is filled between the buffer bladder and the support frame. The shape of the support frame is similar to that of the buffer bladder, that is, the shape of the buffer bladder is a proportionally enlarged version of the shape of the support frame, and the bottom of the support frame has a spherical structure. Specifically, the medium constituting the buffer layer is an inert gas or liquid, wherein the liquid is preferably water. When pressure is applied, it can produce a soft touch similar to the fingertips of a human finger, thereby achieving a more ergonomic biomimetic massage feel.

[0009] Preferably, in this technical solution, the driving unit includes a transmission column, which is fixed to the top of the support frame. The top of the transmission column is connected to the output end of the first motor via a telescopic guide column. The first motor is fixed to the top of the inner cavity of the bearing shell. A thin rod extends from the bottom of the transmission column, and the thin rod passes through the buffer bladder and connects to the support frame. The bearing shell is disposed on the top side wall of the inner cavity of the outer shell. The transmission column is connected to the ejector part via the bearing part. The extension or shortening of the guide telescopic column fixes the path of the composite pressure-relieving massage unit when it is moved by the ejector part, thus playing a guiding role.

[0010] Preferably, in this technical solution, the supporting part includes a supporting sleeve, which is connected to the ejector part via a connecting ring fitted on its outer surface. The supporting sleeve is fitted onto the surface of the transmission column, and a rotating sealing ring and an inner ring of a bearing are fitted onto the surface of the transmission column. The outer ring of the rotating sealing ring and the outer ring of the bearing are both connected to the inner wall of the supporting sleeve. When the ejector part ejects or retracts, it drives the supporting sleeve to move via the connecting ring. The supporting sleeve and the transmission column move synchronously, thereby driving the composite pressure-relieving massage unit to move.

[0011] Preferably, in this technical solution, the telescopic guide post is composed of two tubes that slide and sleeve each other. A limiting plate is fixed on the surface of the inner tube, and the limiting plate is slidably connected to a groove on the inner wall of the outer tube. The limiting plate is arranged along the length direction of the telescopic guide post. The protruding part is a bladder that can protrude outward.

[0012] Preferably, in this technical solution, the ejector portion includes a deformation layer and a sealing shell. The sealing shell is fixed to the top of the inner cavity of the outer shell. A through groove is provided on the bottom side wall of the sealing shell. The through groove is covered with a deformation layer. A connecting ring is fitted on the surface of the deformation layer. At least one air pump is connected to the sealing shell through a pipe.

[0013] Specifically, when the inside of the ejector section is inflated or inhaled, the deformation layer extends or retracts to eject or retract the massage component. When the deformation layer moves, the connecting layer extends or folds to achieve controllable deformation.

[0014] The air pump fills or extracts gas into the sealed cavity formed by the sealing shell and the deformation layer, causing the deformation layer to bulge outward, restore its original shape, or sink inward, thereby driving the composite pressure-relieving massage unit on the support part to move.

[0015] The air pump is connected to an external control element and power supply. The control panel of the control element can be installed on the outer wall of the housing. By pressing the buttons on the control panel, the air pump can be controlled to inflate or depress, thereby causing the deformation layer to deform.

[0016] The composite pressure-relieving massage unit moves by deforming the deformation layer itself. Because the deformation layer itself has a certain degree of extensibility, when the composite pressure-relieving massage unit reaches the massage area and continues to move towards the wrist, the extensibility of the deformation layer itself can prevent the composite pressure-relieving massage unit from excessively squeezing the wrist, thus increasing the error tolerance of the user's manual adjustment.

[0017] In this technical solution, the placement assembly includes a support plate fixed to the bottom side wall of the inner cavity of the outer casing. A lifting part is fixed to the top of the support plate, and a container plate with an arc-shaped cross-section is provided at the top of the lifting part. The lifting part drives the container plate to move vertically. The lifting part is a retractable airbag or a retractable rod, and the rod is an electric push rod or a pneumatic rod. When the lifting part is an airbag, it is connected to an external air pump, and the air pump is installed on the inner side wall of the outer casing. The lifting part drives the support plate for placing the wrist to move vertically, thereby adjusting the height of the wrist.

[0018] This technical solution also includes two side massage components located on either side of the placement component, symmetrically arranged. Each side massage component massages both sides of the wrist, forming a circular massage trajectory with opposite rotation directions on the contact surfaces on both sides of the wrist. In other words, the two side massage components perform a figure-eight massage on both sides of the wrist to relieve wrist pain.

[0019] In this technical solution, the side massage component includes a driving part and a massage part, and the driving part drives the massage part to make a biased circular motion.

[0020] In this technical solution, the driving unit includes a fixed housing, inside which a second motor is fixed. A transmission shaft is fixed to the output end of the second motor. The transmission shaft is Z-shaped, and its end is connected to the massage unit. The second motor drives the transmission shaft to rotate, and the transmission shaft, through a telescopic rod, drives the massage unit to rotate eccentrically relative to the second motor, thereby achieving massage on both sides of the wrist.

[0021] In this technical solution, the massage unit includes a telescopic rod connected to the end of a drive shaft, and the other end of the telescopic rod connected to a massage end. The telescopic rod is composed of two rods that slide and fit together, and the connection between the two rods is covered by a telescopic airbag. The telescopic airbag is connected to an external air pump via an external pipe. Gas is injected into or extracted from the telescopic airbag by the air pump, causing the airbag to deform axially, which in turn extends or shortens the telescopic rod. This causes the massage end to move towards the side of the wrist until it reaches the side of the wrist, where a massage is performed.

[0022] In this technical solution, the massage end includes a base shell connected to a telescopic rod. The base shell is covered with a side massage airbag, and the contact surface between the side massage airbag and the wrist is concave inward to form an arc-shaped structure. The side massage airbag contacts the side of the wrist and then rotates in a deflection direction under the drive of the driving end, thereby massaging the side of the wrist. The second motors on the two side massage components rotate in opposite directions during massage. Multiple buffer balls are externally fixed to the end of the telescopic airbag. The buffer balls are made of a flexible, deformable material, such as rubber, and are interconnected with the inner cavity of the telescopic airbag. The buffer balls have a greater ability to maintain their shape than the telescopic airbag. That is, when the telescopic airbag pushes the massage end against the side of the wrist, it continues to inflate the telescopic airbag, further pressurizing the buffer balls and increasing their volume. The buffer balls can alleviate the pressure between the massage end and the side of the wrist, improving the tolerance for manual adjustment by the user.

[0023] This technical solution also includes a base, which is fixed to the bottom of the outer casing, and a placement slot for placing a hand is provided on the bottom side wall of the outer casing near the rear port. The placement slot allows the hand to have ample space to stretch out.

[0024] This technical solution also includes a support component for supporting the palm. The support component includes a bracket, which is fixed to the base surface below the placement slot. A placement part is provided on the top of the bracket. The placement part includes a connecting part and a support platform. The connecting part is fixed to the bracket, and the support platform is fixed to the top of the connecting part. By setting up a palm support component, the user's hand is in a naturally relaxed state during use, avoiding secondary fatigue caused by suspension or instability. During wrist massage, the palm is aligned with the support platform, and the palm is placed on the support platform. The connecting part is an adjustable-length telescopic rod, with its two ends connected to the bracket and the support platform, respectively. The height of the support platform is adjusted by the telescopic rod. The telescopic rod consists of two tubes of different diameters that slide and fit together. A stud is threaded into the side wall of the outer tube, and the position of the two tubes after length adjustment is locked by the stud. The connecting part includes a protective shell fixed to a bracket. A third motor is fixed inside the protective shell, and a transmission rod is connected to the output end of the third motor. The transmission rod passes through the protective shell and the bracket in sequence and connects to the bottom of the support platform. An outer sleeve is fitted onto the surface of the transmission rod, and the outer sleeve is fixed to the bracket. The third motor drives the support platform to rotate via an inner connecting rod, thereby allowing the hand to be extended through the rotating support platform.

[0025] According to the present invention, at least the following beneficial effects are achieved: The wrist rests on the support assembly; above it is a massage component that can extend outwards, capable of reaching vertically or at an angle according to control commands, and contacting the inner or outer part of the wrist to create a targeted, localized deep massage effect. Specifically, the end of the massage component that contacts the wrist uses a soft, composite pressure-relieving massage unit. This unit consists of an internal support frame and an external flexible airbag layer, with a gas or liquid medium filling the space between the frame and the airbag. When pressure is applied, it produces a soft tactile sensation similar to the pads of human fingers, thus achieving a more ergonomic and biomimetic massage feel.

[0026] Furthermore, compared to existing technologies, the contact points of ordinary massage devices are mostly made of plastic or hard silicone, which can easily cause pressure discomfort in non-weight-bearing areas like the wrist where muscles and bone tissue are relatively thin. This invention utilizes a composite pressure-relieving massage unit to achieve pressure relief and dispersion, significantly improving massage comfort and adaptability; it also avoids soreness or secondary injury caused by hard contact. This structure is particularly suitable for applications such as wrist pain relief, carpal tunnel syndrome intervention, and sports rehabilitation massage, effectively enhancing the user's massage experience and pain relief.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art will understand that this description is exemplary and does not limit the present invention to the embodiments described herein.

[0030] Figure 1-18 Various views are provided to illustrate the overall or partial views of the device for relieving wrist pain according to embodiments of the present invention.

[0031] First, such as Figures 1-4 , Figure 18As shown, the device for relieving wrist pain according to the present invention includes a housing 1. The housing 1 has a front port 11 for inserting the wrist and a rear port 12 for placing the palm on both sides. The front port 11 and the rear port 12 are interconnected. A plurality of upper massage components 6 are arranged in a circular array at the top of the inner cavity of the housing 1 near the front port 11. The central angle of the circular array is less than 50 degrees. The upper massage component 6 includes a soft composite pressure-relieving massage unit that contacts the wrist. The upper massage component 6 is disposed on a softly liftable protruding part, which is disposed in the inner cavity of the housing 1. A wrist placement component 2 is disposed below the upper massage component 6 and is disposed in the inner cavity of the housing 1.

[0032] By using a composite pressure-relieving massage unit to mimic the fingertips of human fingers to massage the wrist, the contact point between the massage device and the wrist is not too hard, which is different from the situation where ordinary massage devices are not subjected to pressure. This provides users with a better massage experience and enhances the pain relief effect.

[0033] The following is a detailed description of the various parts of the device for relieving wrist pain.

[0034] like Figure 5-7 As shown, the composite pressure-relieving massage unit includes a support frame 65, which is fixed to a drive unit. The drive unit is mounted on a support unit, which is mounted on a soft protruding part that drives its movement. A cushioning bladder 66 covers the surface of the support frame 65, and a deformable cushioning layer is filled between the cushioning bladder 66 and the support frame 65. The shape of the support frame 65 is similar to that of the cushioning bladder 66, meaning the shape of the cushioning bladder 66 is a proportionally enlarged version of the shape of the support frame 65, and the bottom of the support frame 65 has a spherical structure. The medium constituting the cushioning layer is an inert gas or liquid, preferably water. When pressure is applied, it produces a soft tactile sensation similar to the fingertips of a human finger, thus achieving a more ergonomic biomimetic massage feel. The cushioning bladder 66 is made of a deformable rubber material, and the medium constituting the cushioning layer fills or fills at least 80% of its internal cavity.

[0035] Furthermore, the drive unit includes a transmission column 61, which is fixed to the top of the support frame 65. The top of the transmission column 61 is connected to the output end of the first motor 63 via a telescopic guide column 62. The first motor 63 is fixed to the top of the inner cavity of the bearing shell 3. A thin rod extends from the bottom of the transmission column 61, and the thin rod passes through the buffer bladder 66 and connects to the support frame 65. The bearing shell 3 is disposed on the top side wall of the inner cavity of the outer shell 1. The transmission column 61 is connected to the ejector part via the bearing part.

[0036] The extension or shortening of the guide telescopic column fixes the path of the composite pressure-relieving massage unit as it moves with the ejector part, thus playing a guiding role.

[0037] Specifically, the first motor 63 drives the transmission column 61 to rotate through the telescopic guide column 62, thereby causing the composite pressure-relieving massage unit at the end of the transmission column 61 to rotate. Through the rotation of the composite pressure-relieving massage unit, the wrist is rubbed and massaged.

[0038] Furthermore, the bearing part includes a bearing sleeve 67, which is connected to the ejector part through a connecting ring 68 fitted on its outer surface. The bearing sleeve 67 is fitted onto the surface of the transmission column 61, and a rotating sealing ring 611 and the inner ring of the bearing are fitted onto the surface of the transmission column 61. The outer ring of the rotating sealing ring 611 and the outer ring of the bearing are both connected to the inner wall of the bearing sleeve 67.

[0039] When the ejector is ejected or retracted, the ejector drives the bearing sleeve 67 to move through the connecting ring 68. The bearing sleeve 67 and the transmission column 61 move synchronously, thereby driving the composite pressure-relieving massage unit to move.

[0040] Specifically, the telescopic guide post 62 is composed of two tubes that slide and fit together. A limiting strip 64 is fixed on the surface of the inner tube. The limiting strip 64 is slidably connected to a groove on the inner wall of the outer tube. The limiting strip 64 is set along the length of the telescopic guide post 62.

[0041] The ejector portion is a bladder that can protrude outwards. The ejector portion includes a deformation layer 5 and a sealing shell 4. The sealing shell 4 is fixed to the top of the inner cavity of the outer shell 1. A through groove is provided on the bottom side wall of the sealing shell 4. The through groove is covered with the deformation layer 5. A connecting ring 68 is fitted on the surface of the deformation layer 5. At least one air pump is connected to the sealing shell 4 through a pipe.

[0042] The deformation layer 5 itself is specifically extensible or the deformation layer 5 protrudes outward, and the four sides of the deformation layer 5 are all covered and connected to the through groove on the surface of the sealing shell 4 through a connecting layer with a pre-folded groove.

[0043] When the inside of the ejector section is inflated or inhaled, the deformation layer 5 extends or retracts to eject or retract the upper massage component 6. When the deformation layer 5 moves, the connecting layer extends or folds to achieve controllable deformation.

[0044] The air pump fills or extracts gas into the sealed cavity formed by the sealing shell 4 and the deformation layer 5, causing the deformation layer 5 to bulge outward, restore its original shape, or sink inward, thereby driving the composite pressure-relieving massage unit on the bearing part to move.

[0045] The air pump is connected to an external control element and power supply. The control panel of the control element can be installed on the outer wall of the housing 1. By pressing the button on the control panel, the air pump can be controlled to inflate or depress, thereby causing the deformation layer 5 to deform and move.

[0046] The deformable layer 5 is used to drive the composite pressure-relieving massage unit to achieve contact and action on the target area of ​​the wrist. The deformable layer 5 is flexible and extensible, and can produce controllable deformation when subjected to external force or driving control, thereby driving the composite pressure-relieving massage unit located at its end to move towards the target massage position.

[0047] When the composite pressure-relieving massage unit comes into contact with the wrist and moves further, the deformable layer 5 has the flexibility to absorb the pressure changes caused by the excess displacement without relying on rigid limits. This effectively avoids excessive pressure or concentrated pressure on the wrist by the composite pressure-relieving massage unit.

[0048] Compared to traditional rigid transmission or fixed-path motion mechanisms, which are prone to excessive contact force and inability to adapt to individual differences, the deformation layer 5 in this invention not only provides flexible transmission but also enables active yielding and buffering adjustment. This significantly improves the device's adaptability to different users' wrist sizes, structural shapes, and pressure perception, thereby significantly enhancing the device's adjustment tolerance and safety in actual use. Even with manual adjustments or wearing errors, users are less likely to experience pain or discomfort due to excessive pressure, resulting in higher user comfort and ergonomics.

[0049] The following provides a detailed explanation of the placement of component 2, etc.

[0050] Specifically, the placement component 2 includes a support plate 21, which is fixed to the bottom side wall of the inner cavity of the outer shell 1. A lifting part 22 is fixed to the top of the support plate 21, and a container plate 23 with an arc-shaped cross section is provided on the top of the lifting part 22. The lifting part 22 drives the container plate 23 to move vertically. The lifting part 22 is a retractable airbag or a retractable rod, and the rod is an electric push rod or a pneumatic rod.

[0051] When the lifting section 22 is an airbag, it is connected to an external air pump, which is installed on the inner cavity side wall of the outer casing 1. The lifting section 22 drives the support plate 21 on which the wrist is placed to move vertically, thereby adjusting the height of the wrist.

[0052] The two side massage components are described in detail below.

[0053] like Figure 8As shown, the device also includes two side massage components 7 located on either side of the placement component 2, symmetrically arranged. Each side massage component 7 massages both sides of the wrist, forming a circular massage trajectory with opposite directions of rotation on the contact surface on both sides of the wrist. In other words, the two side massage components 7 perform a figure-eight massage on both sides of the wrist to relieve wrist pain. Each side massage component 7 includes a driving part and a massage part, the driving part driving the massage part to perform a biased circular motion.

[0054] The drive unit includes a fixed housing 71, inside which a second motor 72 is fixed. A transmission shaft 73 is fixed to the output end of the second motor 72. The transmission shaft 73 is Z-shaped, and the end of the transmission shaft 73 is connected to the massage unit.

[0055] The second motor 72 drives the transmission shaft 73 to rotate, and the transmission shaft 73 drives the massage end to rotate eccentrically relative to the second motor 72 through the telescopic rod 74, so as to massage both sides of the wrist.

[0056] The massage unit includes a telescopic rod 74, which is connected to the end of the drive shaft 73, and the other end of the telescopic rod 74 is connected to the massage end. The telescopic rod 74 is composed of two rods that slide and fit together, and the connection between the two rods is covered by a telescopic airbag 75, which is connected to an air pump through an external pipe 751.

[0057] The following describes the telescopic airbag at the massage end.

[0058] like Figure 9 , Figure 16 , Figure 17 As shown, the telescopic airbag 75 completely covers the connection between the two rods, that is, the air storage cavity of the telescopic airbag 75 is in direct contact with the connection between the two rods, the gas inside the telescopic airbag 75 is in direct contact with the rods, and the connection between the two rods is a sliding sealing structure.

[0059] like Figure 15 As shown, the telescopic airbag 75 has a radially annular structure, meaning that the air storage cavity of the telescopic airbag 75 has a radially annular structure, which directly fits onto the two rods at two points, so the connection between the two rods does not need to be a sliding sealing structure.

[0060] By inflating or deflating the telescopic airbag 75 with an air pump, the telescopic airbag 75 deforms axially, causing the telescopic rod 74 to extend or shorten. This causes the massage end to move towards the side of the wrist until it reaches the side of the wrist, where a massage is then performed.

[0061] The massage end includes a base shell 76 connected to a telescopic rod 74. The base shell 76 is covered with a side massage airbag 77, and the contact surface of the side massage airbag 77 with the wrist is concave inward to form an arc-shaped structure. The side massage airbag 77 contacts the side of the wrist and then rotates in a biased direction under the drive of the driving end, thereby massaging the side of the wrist. The second motors 72 on the two side massage components 7 rotate in opposite directions during massage.

[0062] Multiple buffer balls 752 are externally fixed to the end of the telescopic airbag 75. The buffer balls 752 are made of a stretchable and deformable material, such as rubber, and are in communication with the inner cavity of the telescopic airbag 75. The buffer balls 752 have a greater ability to maintain their own shape than the telescopic airbag 75 has to maintain its formed shape.

[0063] Furthermore, a synergistic structure of a telescopic airbag 75 and a cushioning ball 752 is introduced into the side massage component 7. The telescopic airbag 75 drives the massage end to move towards the side of the wrist. After the airbag is initially inflated, the massage end is pushed to the target massage position on the wrist; after the massage end completes its initial positioning, the airbag continues to inflate, and the internal air pressure further compresses the cushioning ball 752 located within the telescopic airbag 75 along the depth direction.

[0064] The buffer ball 752 is a flexible, closed structure connected to the telescopic airbag 75. When subjected to continuous air pressure input from the telescopic airbag 75, its volume increases accordingly, forming a certain degree of outward bulging deformation. This structure can effectively absorb some of the excess air pressure energy and release the buffer deformation space, thereby establishing a flexible buffer structure between the massage end and the wrist surface.

[0065] While maintaining a stable massage position, it effectively disperses and alleviates localized pressure concentration, significantly improving user comfort during use. This structure also boasts excellent fault tolerance, allowing users to maintain appropriate massage intensity even with slight deviations in airbag inflation. This significantly enhances the device's adaptability and safety margin to manual adjustment errors, making it particularly suitable for massage scenarios in sensitive areas such as the wrist where subcutaneous tissue is thin and bones are prominent.

[0066] The supporting components are described in detail below.

[0067] like Figure 10-15 As shown, the telescopic airbag 75 can also replace the top part, that is, the telescopic airbag 75 is enlarged or reduced proportionally and placed on the telescopic guide post 62 in the upper massage assembly 6. Specifically, the telescopic airbag 75 covers the connection between the two tubes that constitute the telescopic guide post 62, so as to more accurately adjust the position of the composite pressure-relieving massage unit. Each telescopic airbag 75 on the composite pressure-relieving massage unit is externally connected to an air pump.

[0068] like Figure 10 As shown, mounting shells 14 are provided on both sides of the upper massage component 6, and the fixing shell 71 of the side massage component 7 is placed inside the mounting shell 14. Related electrical components such as air pumps can also be installed inside the mounting shell 14. A base 8 is also included, which is fixed to the bottom of the outer shell 1.
