[0041] Please see Figures 1 to 5 The image shows a massage device 100 provided in an embodiment of this application, which includes a housing 10, a first massage part 20, a second massage part 30, and a drive unit 40.

[0042] The first massage unit 20 includes a first contact body 21 and a second contact body 22 respectively disposed on opposite sides of the housing 10, the first contact body 21 and the second contact body 22 together forming a contact space 23. Please refer to [link / reference]. Figure 7 The design of the contact space 23 allows it to easily conform to the area being massaged 52 (such as the arm, leg, neck, etc.), enabling a wrap-around massage of the area 52, resulting in better stability and comfort during the massage. Specifically, the first contact body 21 and the second contact body 22 are arranged on opposite sides of the housing 10 along the lateral direction. The portion of the housing 10 located between the first contact body 21 and the second contact body 22, together with the first contact body 21 and the second contact body 22, forms the contact space 23.

[0043] The second massage unit 30 is connected to the housing 10 and located at the axial end of the contact space 23. When the part of the user's body that needs to be massaged enters the contact space 23 of the first massage unit 20, its head end can extend out of the contact space 23 and interact with the second massage unit 30. For ease of understanding, refer to... Figure 3 , Figure 4 In this coordinate system, the axial direction is the X direction and the transverse direction is the Y direction.

[0044] A drive unit 40 is disposed in the housing 10 and is connected to the second massage unit 30 for transmission, so as to drive the second massage unit 30 to rotate and / or oscillate relative to the first massage unit 20. That is, the drive unit 40 can drive the second massage unit 30 to rotate or oscillate, or rotate and oscillate simultaneously, thereby realizing the rocking and swaying function. Here, rotation refers to the second massage unit 30 rotating at least one full rotation continuously, and oscillation refers to the second massage unit 30 oscillating back and forth within a rotation range of less than one full rotation. The axis of rotation and / or oscillation of the second massage unit 30 does not coincide with the central axis 231 of the contact space 23 of the first massage unit 20. That is, the axis of rotation and / or oscillation of the second massage unit 30 is not on a straight line with the central axis 231 of the contact space 23, so that the second massage unit 30 can not only move in the circumferential direction relative to the massaged part 52 to rub the outer periphery of the massaged part 52, but also make the head end of the massaged part 52 sway up and down and / or left and right, resulting in a better massage effect. For the sake of simplicity, the axis of rotation and / or oscillation of the second massage unit 30 is referred to below as the oscillation axis 34 of the second massage unit 30.

[0045] This application provides a massage device 100. Firstly, a second massage part 30 is arranged at one axial end of a contact space 23, and can work in conjunction with the first massage part 20 through rotation, swinging, or other movements to create a multi-angle, multi-directional massage effect. Secondly, the first contact body 21 and the second contact body 22 together enclose the contact space 23, which can easily fit against massaged areas 52 such as arms, legs, and necks, providing a wrap-around massage and offering better stability and comfort during the massage.

[0046] In one embodiment, the housing 10 includes an inner shell 11 and an outer shell 12 covering the outside of the inner shell 11, with the drive unit 40 disposed within the inner shell 11. Exemplarily, the inner shell 11 is made of a rigid material, including but not limited to rigid plastics such as polypropylene (PP), polyvinyl chloride (PVC), and polycarbonate (PC), thereby providing structural support for the normal operation of its internal components. The outer shell 12 is made of a flexible material, including but not limited to non-toxic, antibacterial silicone with good chemical stability; using soft, skin-friendly materials can improve the user experience of the product.

[0047] In one embodiment, the first massage part 20 is made of a flexible material, including but not limited to non-toxic, antibacterial silicone with good chemical stability. The use of a soft and skin-friendly material in the first massage part 20 can improve the user experience of the product.

[0048] In one embodiment, the second massage part 30 is made of a flexible material, including but not limited to non-toxic, antibacterial silicone with good chemical stability. Similarly, the use of a soft and skin-friendly material for the second massage part 30 can improve the user experience of the product.

[0049] In one embodiment, both the first massage part 20 and the second massage part 30 are integrally molded parts. The integral molding method includes, but is not limited to, injection molding or casting. This ensures that the surfaces of the first massage part 20 and the second massage part 30 are seamless, resulting in a more aesthetically pleasing product and better sealing.

[0050] In one embodiment, please refer to Figure 5 The first massage part 20, the second massage part 30, and the outer shell 12 are integrally molded, thereby further improving the overall consistency and sealing of the product.

[0051] In one embodiment, please refer to Figure 3 The axis of rotation and / or oscillation of the second massage unit 30 is parallel to the central axis 231 of the contact space 23 of the first massage unit 20. Exemplarily, the central axis 231 of the contact space 23 and the oscillation axis 34 of the second massage unit 30 are arranged vertically spaced apart and both extend axially, wherein the vertical direction is as follows: Figure 3 It extends in the Z-direction.

[0052] In one embodiment, the axis of rotation and / or oscillation of the second massage unit 30 is perpendicular to the central axis 231 of the contact space 23 of the first massage unit 20. For example, when the central axis 231 of the contact space 23 extends axially, the oscillation axis 34 of the second massage unit 30 can extend laterally (Y direction), vertically (Z direction), or within the plane formed by the lateral and vertical directions (YZ plane).

[0053] In one embodiment, please refer to Figures 1 to 3 The second massage unit 30 is cylindrical, and its internal space communicates with the contact space 23 of the first massage unit 20 to jointly form a massage space. For example, the second massage unit 30 includes a connecting body 31 and a sleeve 32 connected to one axial end of the connecting body 31. The internal space of the sleeve 32 communicates with the contact space 23 to jointly form the massage space. The swing axis 34 of the second massage unit 30 is parallel to the central axis 231 of the contact space 23. The connecting body 31 is generally rod-shaped, with one end connected to the housing 10 and intersecting the swing axis 34, and the other end extending in a direction inclined to the swing axis 34, so that the connecting body 31 and the sleeve 32 can tilt and / or swing together around the swing axis 34 during the massage state. The angle at which the connecting body 31 extends inclined relative to the swing axis 34 is not particularly limited. For example, the angle at which the connecting body 31 extends obliquely relative to the rocking axis 34 can be between 0° and 90° or less. For example, the angle can be 15°, 30°, 45°, 60°, 75° and 90°.

[0054] In one embodiment, the second massage portion 30 opens towards the side of the first massage portion 20, and closes towards the side of the first massage portion 20; alternatively, both ends of the second massage portion 30 are open. That is, the internal space of the sleeve body 32 can be open at one end towards the contact space 23 and closed at the opposite end, or it can be open at both ends. For an example, please refer to... Figure 3 The sleeve body 32 has a massage cavity 321 that opens towards the contact space 23. The massage cavity 321 is connected to the contact space 23 to jointly form the massage space.

[0055] In one embodiment, the internal space of the second massage unit 30 is substantially coaxial with the contact space 23 of the first massage unit 20. That is, the axis of the internal space of the second massage unit 30 and the central axis 231 of the contact space 23 can be completely coaxial or approximately coaxial. For example, these two axes can be parallel, intersecting, or even skewed. When the two axes are parallel or skewed, the shortest distance between them is small, for example, the shortest distance can be less than or equal to 5 mm; when the two axes intersect, the included angle between them is small, for example, the included angle between them can be less than or equal to 5°.

[0056] In one embodiment, please refer to Figure 8 The second massage portion 30 is sheet-like or block-like, and extends obliquely from the side end of the housing 10 relative to the axis of rotation and / or oscillation of the second massage portion 30. Exemplarily, the second massage portion 30 includes a connecting body 31 and an ellipsoid 33, with the housing 10 and the ellipsoid 33 respectively connected at their axial ends. The connecting body 31 is generally rod-shaped, intersecting the oscillation axis 34, and its other end extends in a direction inclined to the oscillation axis 34, so that the connecting body 31 and the ellipsoid 33 can jointly rotate and / or oscillate around the oscillation axis 34 in the massage state. The angle at which the connecting body 31 extends obliquely relative to the oscillation axis 34 is as described in the above embodiment and will not be repeated here.

[0057] In one embodiment, please refer to Figures 1 to 4 Both the first contact body 21 and the second contact body 22 are arc-shaped sheets. The ends of the first contact body 21 and the second contact body 22 are spaced apart along the circumference of the contact space 23, so that they will not interfere with each other when moving relative to each other. The arc-shaped curved surface structure can better fit the massaged parts 52 such as the arms, legs or neck, effectively disperse pressure and avoid discomfort caused by single-point pressure.

[0058] In one embodiment, please refer to Figure 8An elastomer 50 is connected between the ends of the first contact 21 and the second contact 22. The elastomer 50 provides a flexible connection, allowing the first contact 21 and the second contact 22 to stretch, compress, or bend within a suitable range, improving the product's coverage and adapting to different user body shapes or the size of the massaged area 52. The elastomer 50 is a flexible material, including but not limited to non-toxic, antibacterial silicone with good chemical stability.

[0059] In one embodiment, the massage device 100 further includes a vibration motor 51. The vibration motor 51 enables the massage to have a high-frequency vibration effect. The position of the vibration motor 51 is not particularly limited.

[0060] For example, in one embodiment, please refer to Figures 4 to 6 A vibration motor 51 is embedded in the first massage section 20. In another embodiment, please refer to... Figure 3 , Figure 5 and Figure 6 A vibration motor 51 is embedded in the second massage section 30. In another embodiment, please refer to... Figure 11 and Figure 12 A vibration motor 51 is embedded in the housing 10. By placing the vibration motor 51 in different positions, multi-directional and multi-angle massage can be achieved, improving the massage experience of the product.

[0061] In one embodiment, please refer to Figures 3 to 5 The drive unit 40 is also connected to the first massage unit 20 to drive the first contact body 21 and the second contact body 22 to move towards or away from each other. In other words, the drive unit 40 can drive the first massage unit 20 to perform a pinching motion, thereby changing the radial dimension of the contact space 23 corresponding to the first contact body 21 and the second contact body 22. By continuously adjusting the size of the contact space 23, a continuous pinching rhythm is generated, which can simulate the natural feel of a real massage, promote blood circulation in the massaged area 52, and make the experience more comfortable.

[0062] The movement of the first contact body 21 and the second contact body 22 towards or away from each other can take the form of relative sliding or relative oscillation. For example, in one embodiment, please refer to... Figures 3 to 6 The drive unit 40 includes a first swing arm 41 and a second swing arm 42 arranged opposite to each other. The first swing arm 41 and the second swing arm 42 are rotatably connected to the housing 10, driving the first contact body 21 and the second contact body 22 to swing towards or away from each other. That is, the rotation of the first swing arm 41 and the second swing arm 42 relative to the housing 10 drives the first contact body 21 and the second contact body 22 to swing.

[0063] In one embodiment, please refer to Figures 3 to 6The drive unit 40 includes a drive motor 43, a first transmission assembly 44, and a second transmission assembly 46. The first transmission assembly 44 is connected between the drive motor 43 and the first massage part 20, and the second transmission assembly 46 is connected between the drive motor 43 and the second massage part 30. Specifically, the drive motor 43 is disposed within the housing 10. The first transmission assembly 44 is configured to convert the rotation of the drive motor 43 into reciprocating oscillation of the first contact body 21 and the second contact body 22 in the lateral direction. The second transmission assembly 46 is configured to convert the rotation of the drive motor 43 into rotation and / or oscillation of the second massage part 30.

[0064] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The first transmission assembly 44 includes an eccentric wheel 441 and a slider 442. The eccentric wheel 441 rotates around the drive axis under the action of the drive motor 43. A first shaft 443 extends outward from the eccentric wheel 441 and is eccentrically arranged relative to the drive axis. The slider 442 is provided with a groove 444, in which the first shaft 443 is movably inserted. One end of the first rocker arm 41 and one end of the second rocker arm 42 are movably connected to the slider 442, and the other ends extend into the first contact body 21 and the second contact body 22, respectively. In other words, the eccentric wheel 441 also includes a first shaft 443. The connecting end of the first rocker arm 41 and the connecting end of the second rocker arm 42 are both connected to the slider 442 and move together with the slider 442. The swinging end of the first rocker arm 41 and the swinging end of the second rocker arm 42 are respectively sleeved in the first contact body 21 and the second contact body 22. The drive axis is the rotation axis of the output shaft of the drive motor 43. The drive motor 43 drives the eccentric wheel 441 to rotate around the drive axis. The first shaft 443 located on the eccentric wheel 441 revolves relative to the drive axis. The first shaft 443 drives the slider 442 to slide. The slider 442 eventually drives the first rocker arm 41 and the second rocker arm 42 to swing towards or away from each other, thereby realizing the swinging of the first contact body 21 and the second contact body 22 towards or away from each other.

[0065] For example, in one embodiment, please refer to Figure 3 and Figure 6An eccentric wheel 441 is torque-transmittedly connected to a drive motor 43. The eccentric wheel 441 extends axially and rotates around the drive axis of the drive motor 43. The central axis 231 of the eccentric wheel 441 is eccentrically arranged with respect to the drive axis. A first shaft 443 extends axially and is slidably inserted into a transversely extending groove 444. The first transmission assembly 44 also includes a pair of vertically extending and parallel-spaced guide rails 447. A slider 442 is slidably mounted on the pair of guide rails 447. Both guide rails 447 are fixedly connected to the housing 10 and are used to guide the sliding direction of the slider 442. When the drive motor 43 drives the eccentric wheel 441 to rotate, the first shaft 443 revolves relative to the drive axis. The first shaft 443 slides within the groove 444 and drives the slider 442 to perform linear reciprocating motion on the vertically extending pair of guide rails 447.

[0066] In one embodiment, please participate Figure 6 The slider 442 has a first sliding rod 445 and a second sliding rod 446 extending axially, respectively. A first groove 411 is formed at the connecting end of the first swing arm, and a second groove 421 is formed at the connecting end of the second swing arm. The first sliding rod 445 is slidably inserted into the first groove 411, and the second sliding rod 446 is slidably inserted into the second groove 421. That is, during the vertical sliding process of the slider 442, the first sliding rod 445 and the second sliding rod 446 will slide within the first groove 411 and the second groove 421, respectively.

[0067] In one embodiment, please participate Figure 4 and Figure 6The first transmission assembly 44 includes a first pivot 450 and a second pivot 451, both extending axially and arranged parallel to each other at intervals. Optionally, the first swing arm 41 and the second swing arm 42 are rotatably engaged with the first pivot 450 and the second pivot 451, respectively, and the first pivot 450 and the second pivot 451 are both fixedly engaged with the housing 10; or, the first swing arm 41 and the second swing arm 42 are fixedly engaged with the first pivot 450 and the second pivot 451, respectively, and the first pivot 450 and the second pivot 451 are rotatably engaged with the housing 10; or, the first swing arm 41 and the second swing arm 42 are rotatably engaged with the first pivot 450 and the second pivot 451, respectively, and the first pivot 450 and the second pivot 451 are also rotatably engaged with the housing 10. The first pivot 450 is rotatably connected between the connecting end of the first swing rod 41 and the swinging end of the first swing rod 41, that is, the first pivot 450 is approximately connected to the middle of the first swing rod 41; the second pivot 451 is pivotally connected between the connecting end of the second swing rod 42 and the swinging end of the second swing rod 42, that is, the second pivot 451 is approximately connected to the middle of the second swing rod 42. The slider 442 drives the first slider 445 and the second slider 446 to generate vertical displacement and slide in the first strip groove 411 and the second strip groove 421, which will drive the connecting end of the first swing rod 41 and the connecting end of the second swing rod 42 to swing around the first pivot 450 and the second pivot 451 respectively, so that the swinging end of the first swing rod 41 and the swinging end of the second swing rod 42 swing around the first pivot 450 and the second pivot 451 respectively, thereby causing the first contact body 21 and the second contact body 22 to swing in opposite directions or in opposite directions in the lateral direction.

[0068] In one embodiment, please refer to Figure 3 and Figure 6The second transmission assembly 46 includes a second shaft 461, one end of which is connected to an eccentric wheel 441, and the other end of which extends obliquely into the second massage unit 30 relative to the axis of rotation and / or oscillation of the second massage unit 30. Specifically, the eccentric wheel 441 includes a first segment 448, a second segment 449, and a first shaft 443 connected between the first segment 448 and the second segment 449. The centerlines of the first segment 448 and the second segment 449 coincide, and the centerline of the first shaft 443 is eccentrically arranged relative to the centerlines of the first segment 448 and the second segment 449. The second transmission assembly 46 also includes a bushing 462, which is disposed within the second massage unit 30. One axial end of the second shaft 461 is torque-driven to the second segment 449, and the other axial end extends obliquely into the second massage unit 30 relative to the oscillation axis 34 and is slidably disposed within the bushing 462. The drive motor 43 drives the first segment 448, the second segment 449, and the first shaft 443 of the eccentric wheel 441 to rotate around the drive axis. The first shaft 443 drives the slider 442 to slide vertically back and forth. The slider 442 drives the first swing arm 41 and the second swing arm 42 to swing laterally towards or away from each other, thereby realizing the swinging of the first contact body 21 and the second contact body 22 towards or away from each other. At the same time, the drive axis is the swing axis 34 of the second massage part 30. The second segment 449 drives the second shaft 461 to rotate around the drive axis. The second shaft 461 extends at an angle relative to the drive axis to one end that extends into the second massage part 30, and drives the second massage part 30 to tilt and rotate and / or swing around the drive axis. In this way, through the pinching action of the first contact body 21 and the second contact body 22 of the first massage part 20 combined with the swinging action of the second massage part 30, the massaged part 52 can be massaged in multiple directions and angles, resulting in a better massage effect and experience for the user.

[0069] In some embodiments, please refer to Figure 6 The eccentric wheel 441 is a single-piece structure, resulting in good overall structural strength. In other embodiments, the first segment 448 and the first shaft 443 are a single-piece structure. Alternatively, the first shaft 443 and the second segment 449 are a single-piece structure. Or, the first segment 448, the first shaft 443, and the second segment 449 are all separate structures, with the eccentric wheel 441 assembled by sequentially and fixedly connecting the first segment 448, the first shaft 443, and the second segment 449, thereby further reducing the processing difficulty of the eccentric wheel 441 and lowering manufacturing costs.

[0070] In one embodiment, please refer to Figures 9 to 12One axial end of the second shaft 461 is directly connected to the drive motor 43 for torque transmission, and the other axial end of the second shaft 461 extends obliquely relative to the swing axis 34 into the second massage part 30 and is slidably disposed within the bushing 462, thereby driving the second massage part 30 to tilt and rotate and / or swing around the drive axis. In other words, without the need for the first massage part 20 to perform a pinching action, the second shaft 461 can be directly connected to the output shaft of the drive motor 43 for torque transmission, thereby driving the second massage part 30 to tilt and rotate and / or swing around the drive axis to achieve a massage effect.

[0071] In one embodiment, please refer to Figures 4 to 6 The massage device 100 also includes a battery 53 for power supply, which is electrically connected to the drive motor 43 and the vibration motor 51. The battery 53 can be a removable battery for easy replacement by the user; the battery 53 can also be a rechargeable battery fixedly installed inside the housing 10.

[0072] In one embodiment, please refer to Figures 4 to 6 The massage device 100 also includes a circuit board 54 electrically connected to the battery 53 and the drive motor 43 respectively. The housing 10 is provided with control buttons. Users can use the control buttons to operate the circuit board 54 to start, stop and adjust the speed of the drive motor 43, as well as control the start and stop of the vibration motor 51 and the vibration frequency.

[0073] This application achieves multiple massages on the massaged area 52 through the swinging and vibration of the first massage unit 20 and the swaying and vibration of the second massage unit 30. It should be understood that the first massage unit 20 and the second massage unit 30 can also have other forms of movement, as long as they can produce a massage effect on the user; this application does not impose any restrictions on this. Furthermore, the two massage units 20 and 30 can have different or the same movement patterns. In use, the user can activate both massage units 20 and 30 simultaneously as needed, or activate only one of them.

[0074] Finally, it should be noted that the above description only depicts preferred embodiments of this application and does not constitute a limitation on the scope of protection of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art will recognize that the technical solutions described in the foregoing embodiments can still be modified or some technical features can be equivalently replaced.
