[0045] See also Figures 1 to 6 , shown is a massage device 100 provided in one embodiment of the present application. The massage device defines a longitudinally extending massage space 100a and includes at least two massage arms 1 and a drive assembly 2. Specifically, the massage space 100a is used to accommodate the area to be massaged by the user. The number of massage arms 1 is at least two. Specifically, the number of massage arms 1 can be two, three, four, or more. More massage arms 1 provide a greater contact area with the area to be massaged within the massage space 100a, providing a more comprehensive massage effect and enhancing the user experience.

[0046] The at least two massage arms 1 include a first massage arm 11 and a second massage arm 12, respectively, disposed on opposite sides of the massage space 100a. The drive assembly 2 is in transmission connection with the at least two massage arms 1 and is configured to drive the first massage arm 11 and the second massage arm 12 to slide, causing the first massage arm 11 and the second massage arm 12 to move closer to or further from each other, thereby changing the radial dimensions of the massage space 100a corresponding to the first massage arm 11 and the second massage arm 12. It should be noted that the longitudinal direction refers to the extension direction of the massage space 100a, and the radial direction refers to a direction perpendicular to the extension direction of the massage space 100a.

[0047] The massage device 100 provided in the embodiment of the present application drives at least two massage arms 1 symmetrically arranged relative to the massage space 100a to move closer to or away from each other through the drive component 2, which can change the radial size of the massage space 100a corresponding to the first massage arm 11 and the second massage arm 12. On the one hand, the overall structure of the device is simple and compact. The user can adjust the radial size between the two massage arms 1 by controlling the drive component 2, which can provide a more personalized and comfortable massage experience, and the user experience of the product is higher. On the other hand, more massage arms 1 can achieve a more comprehensive massage effect on the area to be massaged in the massage space 100a, further improving the user experience of the product. Figure 13 As shown, when using the massage device 100, the user can extend his arms into the massage space 100a, and the first massage arm 11 and the second massage arm 12 clamp and massage the wrist to relax the muscles and relieve muscle fatigue and pain.

[0048] See also Figure 3 、 Figure 5 and Figure 6 The drive assembly 2 includes a drive mechanism 21 having a rotational output shaft 2121 and a pusher 22 threadedly engaged with the rotational output shaft 2121. Rotation of the rotational output shaft 2121 drives the pusher 22 to move longitudinally. The first massage arm 11 and the second massage arm 12 each include at least one slider 13, which slidably engages with the pusher 22, such that axial movement of the pusher 22 drives the slider 13 to slide radially. In other words, the drive assembly 2 converts rotational motion into linear motion. Rotation of the rotational output shaft 2121 of the drive assembly 2 drives the pusher 22 to slide longitudinally along the extension of the massage space 100a. The sliding engagement between the pusher 22 and the slider 13 of the massage arm 1 causes the slider 13 to slide radially, perpendicular to the longitudinal direction. This, in turn, causes the first massage arm 11 and the second massage arm 12 to slide radially.

[0049] The manner in which the drive assembly 2 can convert the rotational movement into the linear motion is not particularly limited. For example, on one hand, the drive assembly 2 can be driven by a screw mechanism, and the screw thread on the screw is slidably matched with the pusher 22 to convert the rotational motion of the screw into the linear motion of the pusher 22 along the axis of the screw. For example, in one embodiment, see Figure 3 、 Figure 5 and Figure 6 The drive assembly 2 includes a transmission mechanism 23, which comprises a longitudinally extending screw 231 and a latch 232. The screw 231 is connected to the rotation output shaft 2121 and rotates synchronously therewith. A spiral groove is formed on the circumferential sidewall of the screw 231. One end of the latch 232 is slidably disposed within the spiral groove, while the other end of the latch 232 is fixedly connected to the longitudinal end of the pusher 22 away from the massage arm 1. Rotation of the screw 231 causes the latch 232 in the spiral groove to slide linearly in the longitudinal direction, thereby causing the pusher 22, which is fixedly connected to the latch 232, to slide linearly in the longitudinal direction. Specifically, in one embodiment, the transmission mechanism 23 includes a sleeve 233 that is sleeved around the outer circumference of the screw 231. The longitudinal end of the pusher 22 away from the massage arm 1 is engaged with the sleeve 233. The sleeve 233 is used to constrain the pusher 22 to rotate circumferentially with the screw 231. For example, the circumferential profile of the sleeve 233 can be a quadrilateral, pentagonal, or hexagonal shape.

[0050] On the other hand, a cam mechanism can also be used for transmission, where the rotation of the cam drives the cam follower (such as the pusher 22 in the embodiment of the present application) to perform linear motion. Adjusting the specific shape of the cam can also adjust the motion trajectory of the pusher 22. On the other hand, a rack and pinion mechanism can also be used for transmission, where the rotation of the gear drives the meshing rack to perform linear motion. The rotation of the gear is converted into linear motion of the rack through the meshing of the teeth. The linear motion of the pusher 22 can be achieved by simply fixing the rack to the pusher 22. In addition, a transmission mechanism 23 such as a crank slider 13 mechanism can also be used, which will not be described in detail here.

[0051] The sliding block 13 and the pushing member 22 are slidably engaged with each other, so that when the pushing member 22 slides in the axial direction, the sliding block 13 is driven to slide in the radial direction. For example, in some embodiments, the pushing member 22 is provided with a wedge, and the sliding block 13 has an inclined surface that cooperates with the wedge. When the pushing member 22 slides in the longitudinal direction, the wedge compresses the sliding block 13 via the inclined surface, causing it to slide in the radial direction.

[0052] In some embodiments, the pusher 22 and the slider 13 form a sliding fit via a groove 221 and a protrusion 131. A groove 221 is formed on one of the pusher 22 and the slider 13, and a protrusion 131 is formed on the other of the pusher 22 and the slider 13. The protrusion 131 slides within the groove 221. The structural positions of the groove 221 and the protrusion 131 are not particularly limited. Specifically, when the pusher 22 is provided with a groove 221, a corresponding protrusion 131 is provided on the slider 13; and when the pusher 22 is provided with a protrusion 131, a corresponding groove 221 is provided on the slider 13. In other words, the pusher 22 and the slider 13 are connected together via the groove and the protrusion 131. Thus, when the pusher 22 moves, the protrusion 131 slides within the groove, driving the slider 13 to move along with it.

[0053] In some implementations, see Figure 5 、 Figure 6 and Figure 11 , a protrusion 131 is provided on the slider 13, and a first slide groove 221a and a first slide groove 221b corresponding to the slider 13 of the first massage arm 11 and the second massage arm 12 are provided on the pushing member 22, respectively. The first slide groove 221a and the first slide groove 221b are both inclined relative to the longitudinal direction. Specifically, the portion of the pushing member 22 close to the first massage arm 11 and the second massage arm 12 is roughly a plate-like structure, and the first slide groove 221a and the first slide groove 221b are both formed on the plate-like structure. The first slide groove 221a and the first slide groove 221b are both strip groove structures. The protrusions 131 on the sliders 13 of the first massage arm 11 and the second massage arm 12 are both rod-shaped structures extending vertically, and the rod-shaped structures are respectively inserted into the first slide groove 221a and the first slide groove 221b. Since the first slide groove 221a and the first slide groove 221b are both inclined relative to the longitudinal direction, when the pusher 22 slides in the longitudinal direction, the first slide groove 221a and the first slide groove 221b respectively abut against the peripheral side walls of the slider 13 of the first massage arm 11 and the second massage arm 12, so that the slider 13 slides in the radial direction within the slide groove 221, thereby allowing the first massage arm 11 and the second massage arm 12 to slide in the radial direction.

[0054] In some embodiments, along the longitudinal direction, the first chute 221a and the first chute 221b gradually approach or gradually move away. That is, the radial dimension of the interval between the first chute 221a and the first chute 221b can be gradually reduced or gradually increased. For example, the extension direction of the first chute 221a can be parallel to the longitudinal direction, and the extension direction of the first chute 221b can be inclined at a certain angle relative to the extension direction of the first chute 221a; or, the extension direction of the first chute 221b can be parallel to the longitudinal direction, and the extension direction of the first chute 221a can be inclined at a certain angle relative to the extension direction of the first chute 221a. Alternatively, in some embodiments, please refer to Figure 5 、 Figure 6 and Figure 11 The extension direction of the first chute 221a and the extension direction of the first chute 221b are not parallel to the longitudinal direction, and the first chute 221a and the first chute 221b are arranged in a V-shape or a truncated V-shape. In other words, the extension direction of the first chute 221a and the extension direction of the first chute 221b form an angle. The range of the angle is not particularly limited and can be set as needed between greater than 0 degrees and less than 180 degrees, for example, 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, etc. In the V-shaped arrangement, one end of the extension direction of the first chute 221a and the first chute 221b intersects; in the truncated V-shaped arrangement, one end of the extension direction of the first chute 221a and the first chute 221b does not intersect.

[0055] In some implementations, see Figure 5 、 Figure 6 and Figure 11 The massage device 100 further includes a guide member 3, which is fixedly arranged to guide the sliding direction of the slider 13. The guide member 3 is provided with a guide groove 3a corresponding to the slider 13, and the guide groove 3a extends substantially in the radial direction. Specifically, the guide member 3 is generally in a groove-shaped structure, and the guide member 3 can be fixed to the main body 4 or the shell 7 to ensure that the guide member 3 is relatively fixed relative to the overall position of the massage device 100. The shell 7 and the main body 4 include, but are not limited to, hard plastics such as polypropylene (PP), polyvinyl chloride (PVC), and polycarbonate (PC), thereby providing structural support for the normal operation of its internal structural components. The guide groove 3a extending substantially in the radial direction means that the guide groove 3a can be consistent with the radial direction or have a certain angle with the radial direction. The range of the angle is not particularly limited and can be set as needed between greater than or equal to 0 degrees and less than or equal to 20 degrees, for example, the angle is 0 degrees, 10 degrees, 20 degrees, etc. For example, in one embodiment, one end of the guide member 3 away from the massage arm 1 is open to form a guide groove 3a and extends radially. The slider 13 can be radially slidably embedded in the guide groove 3a. The guide member 3 can assist the pusher 22 to push the slider 13 to slide radially more smoothly.

[0056] In some implementations, see Figure 2 and Figure 3 The drive mechanism 21 includes a motor 211 and a reduction gear set 212. The input end of the reduction gear set 212 is in driving connection with the rotating shaft of the motor 211, and the rotary output shaft 2121 serves as the output end of the reduction gear set 212. In other words, the reduction gear set 212 can adjust the output speed of the rotary output shaft 2121 and increase the output torque, thereby improving the control accuracy of the massage device 100 and reducing the workload of the motor 211. This ensures that the massage device 100 can more stably perform its massage function, ensuring operational reliability and enhancing the user's product experience.

[0057] In some implementations, see Figures 1 to 6 The massage device 100 is constructed as a claw-like structure. The massage device 100 also includes a main body 4, at least two massage arms 1 are respectively arranged on both sides of the main body 4 in the radial direction, one end of each massage arm 1 is slidably connected to the main body 4, and the second ends 14 of the first massage arm 11 and the second massage arm 12 are bent and extended toward each other. The at least two massage arms 1 and the main body 4 enclose a massage space 100a. Specifically, the drive assembly 2 is disposed in the main body 4. The number of the at least two massage arms 1 can be two, three, four, or even more, but at least two massage arms 1 are arranged radially opposite each other. In other words, the massage space 100a is confined to the area enclosed by the main body 4 and the multiple massage arms 1. Figure 13 As shown, when using the massage device 100, the user can extend his arms into the massage space 100a, and the first massage arm 11 and the second massage arm 12 clamp and massage the wrist to relax the muscles and relieve muscle fatigue and pain.

[0058] In some implementations, see Figure 1 The second ends 14 of the first massage arm 11 and the second massage arm 12 are spaced apart from each other or connected by a flexible member. In other words, the ends of the massage arms 1 away from the main body 4 can be spaced apart from each other or connected by a flexible member, including but not limited to flexible and flexible silicone. This flexible member can further enhance the wrapping feeling of the massage space 100a, providing a better user experience.

[0059] In some implementations, see Figures 4 to 6The massage device 100 further includes at least one vibration member 5, which is disposed in one of the at least two massage arms 1. In other words, the number of vibration members 5 can be one, two, or even more. One vibration member 5 can be disposed in each massage arm 1, or one vibration member 5 can be disposed in only one of the massage arms 1, or multiple vibration members 5 can be disposed in one massage arm 1, without any particular limitation. The vibration member 5 can be a vibration motor 211, including but not limited to an eccentric vibration motor, a linear vibration motor, an electromagnetic vibration motor, and the like.

[0060] In some embodiments, the massage arm 1 includes a soft material disposed on at least one side facing the massage space 100a. The soft material includes, but is not limited to, non-toxic, antibacterial, and chemically stable silicone. The portion of the massage arm 1 in contact with the user within the massage space 100a is soft and skin-friendly, providing a good user experience.

[0061] In some embodiments, the massage arm 1 includes a soft sleeve 233 disposed on its periphery. Similarly, the material of the soft sleeve 233 includes, but is not limited to, non-toxic, antibacterial, and chemically stable silicone. The use of the soft sleeve 233 ensures that all areas of the massage arm 1 are made of a soft, skin-friendly material, further improving the user experience of the product.

[0062] In some implementations, see Figures 1 to 6 The massage device 100 includes a soft shell 6, which is a one-piece molded part. At least two massage arms 1 and the drive assembly 2 are disposed in the soft shell 6. The one-piece molded soft shell 6 has better integrity and sealing performance, and has better product consistency and aesthetics, which is more conducive to product sales and user experience.

[0063] In some implementations, see Figures 7 to 12The massage device 100 includes an outer shell 7 and an inner cylinder 8 arranged inside the outer shell 7. The inner cylinder 8 includes a soft material arranged on one side facing the massage space 100a. An accommodating cavity 100b is formed between the outer shell 7 and the inner cylinder 8. At least two massage arms 1 are arranged in the accommodating cavity 100b. The inner side of the inner cylinder 8 defines the massage space 100a, and the first massage arm 11 and the second massage arm 12 are respectively arranged on both sides of the radial direction of the inner cylinder 8. Exemplarily, the outer shell 7 is a roughly hollow cylindrical structure, and a soft material is provided on the inner side of the inner cylinder 8. The soft material includes but is not limited to silicone that is non-toxic, antibacterial, and has good chemical stability. The accommodating cavity 100b between the outer shell 7 and the inner cylinder 8 is used to accommodate multiple massage arms 1 and a drive assembly 2. The first massage arm 11 and the second massage arm 12 are respectively provided on both sides of the radial direction of the inner cylinder 8, wherein the portions of the inner cylinder 8 that are in contact with the first massage arm 11 and the second massage arm 12 are made of a flexible soft material to ensure that the radial dimensions of the inner cylinder 8 can be changed when the first massage arm 11 and the second massage arm 12 slide relative to each other in the radial direction, thereby achieving a massage effect. Of course, the inner cylinder 8 can also be completely composed of an integrally formed soft material to ensure that the massage space 100a has a higher degree of comfort and further improve the user experience of the product. Figure 14 As shown, when using the massage device 100, the user can extend his arms into the massage space 100a, and the first massage arm 11 and the second massage arm 12 clamp and massage the wrist to relax the muscles and relieve muscle fatigue and pain.

[0064] In some embodiments, see Figure 9 , one longitudinal end of the inner tube 8 is open, and the other longitudinal end is closed. In other words, at least one of the longitudinal ends of the inner tube 8 is open to ensure that the user can extend the part to be massaged into the massage space 100a through the opening.

[0065] In other embodiments, both longitudinal ends of the inner cylinder 8 are open. The user can insert the part to be massaged into the massage space 100a through the longitudinal openings, making the product more convenient to use.

[0066] In some implementations, see Figure 9 The inner cylinder 8 is integrally formed. The integrally formed inner cylinder 8 has better integrity, higher sealing, better consistency and aesthetics of the product, and is more conducive to product sales and user experience.

[0067] In some embodiments, the inner cylinder 8 is formed by at least two ring structures spliced ​​end to end in the longitudinal direction. That is, the inner cylinder 8 may also be formed by multiple ring structures spliced ​​end to end in the longitudinal direction. When the internal structure of the inner cylinder 8 is relatively complex, such as an inner cylinder 8 with inconsistent wall thickness or a curved axis, the splicing method can facilitate product processing and reduce the production cost of the inner cylinder 8.

[0068] In some implementations, see Figure 5 and Figure 12 Massage device 100 also includes a battery 91 and a control board 92. The circuit board is electrically connected to drive assembly 2, and battery 91 is electrically connected to both the circuit board and drive assembly 2.
