[0037] Please see Figures 1 to 7 The image shows a massage device 100 provided in an embodiment of this application. The massage device 100 forms a massage space 10, which can be used to accommodate the user's arms, legs, neck, and other parts that need massage. Specifically, the massage device 100 includes a massage unit 20 and a drive unit 30, wherein the massage space 10 is formed by the massage unit 20.

[0038] The massage unit 20 includes a first massage portion 21 and a second massage portion 22 disposed around the massage space 10. Exemplarily, in one embodiment, the first massage portion 21 and the second massage portion 22 are generally arc-shaped, together forming a generally cylindrical massage space 10, the central axis of which extends along a first direction. For ease of understanding, refer to... Figure 3 , Figure 6 as well as Figure 7In the coordinate system described herein, the first direction is exemplified by the X direction. The first massage unit 21 and the second massage unit 22 are located on opposite sides of the massage space 10 along the second direction, i.e., the Y direction, wherein the second direction is perpendicular to the first direction. In other embodiments, the massage unit 20 may further include a third massage unit, a fourth massage unit, or more massage units, each massage unit being arranged around the massage space 10. Each massage unit may be designed with a corresponding structure according to the massage space 10 to better adapt to the different sizes and shapes of the massaged parts such as the arms, legs, and neck.

[0039] The drive unit 30 includes a first drive section 40 and a second drive section 50. The first drive section 40 is driveably connected to the second drive section 50 to drive the second drive section 50 and the massage unit 20 to move along a first direction. The second drive section 50 is driveably connected to the massage unit 20 to drive the first massage section 21 and the second massage section 22 to move towards or away from each other, thereby changing the size of the massage space 10 located at the first massage section 21 and the second massage section 22. Exemplarily, in one embodiment, the first drive section 40 is used to drive the second drive section 50 to reciprocate along the first direction, and the second drive section 50 is used to drive the first massage section 21 and the second massage section 22 to move towards or away from each other in a plane perpendicular to the first direction.

[0040] In other words, the massage device 100 provided in this application embodiment can drive the massage unit 20 to achieve linear movement along the first direction through the first drive part 40, and can also drive the first massage part 21 and the second massage part 22 of the massage unit 20 to move closer or further apart to achieve a pinching action through the second drive part 50. This allows for massage of different positions of the massaged parts such as the arms, legs, and neck, making the massage effect closer to that of a manual massage, helping to relax muscles, relieve fatigue, improve blood circulation, and provide better comfort during the massage.

[0041] In one embodiment, please refer to Figure 7 and Figure 8 The drive unit 30 includes a drive assembly 60 with a rotation output shaft 621. The drive assembly 60 provides driving force for the movement of the massage device 100. Exemplarily, in one embodiment, the drive assembly 60 includes a drive motor 61 and a reduction gear set 62. The drive motor 61 is connected to the input end of the reduction gear set 62, and the rotation output shaft 621 is the output end of the reduction gear set 62. The reduction gear set 62 can adjust the output speed of the rotation output shaft 621 and increase the output torque, thereby improving the control precision of the massage device 100, reducing the workload of the motor, and ensuring that the massage device 100 can more stably perform the massage function, guaranteeing operational reliability and the user's product experience.

[0042] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 The first drive unit 40 is connected between the rotary output shaft 621 and the second drive unit 50. The first drive unit 40 is configured to convert the rotation of the rotary output shaft 621 about an axis extending in a first direction into linear reciprocating sliding of the second drive unit 50 along the first direction. The implementation method by which the first drive unit 40 converts rotation into linear reciprocating sliding is not particularly limited. For example, the first drive unit 40 can employ a lead screw mechanism; please refer to [reference needed]. Figure 3 , Figure 6 and Figure 8 The first drive unit 40 includes a rotating member 41, a sliding member 42, and a pin 43. A rotating output shaft 621 connects to the rotating member 41, and a spiral groove 411 is formed on the outer periphery of the rotating member 41. The pin 43 is fixed to the sliding member 42 and slidably inserted into the spiral groove 411. The second drive unit 50 is disposed on the sliding member 42. Specifically, the rotating output shaft 621 drives the rotating member 41 to rotate. One end of the pin 43 slides within the spiral groove 411 and performs a linear reciprocating motion relative to the rotating member 41 in the X direction. The other end of the pin 43 is fixedly connected to the sliding member 42. The sliding member 42 and the second drive unit 50 are fixedly engaged in the X direction, and the second drive unit 50 also performs a linear reciprocating sliding motion in the X direction.

[0043] In one embodiment, the first drive unit 40 includes a guide member 44 fixedly disposed in the massage device 100. The guide member 44 has a guide groove 441 extending along a first direction, and a pin 43 is slidably inserted into the guide groove 441. The guide member 44 can limit the rotation of the slider 42, preventing the slider 42 from rotating circumferentially with the rotating member 41 along the axis extending in the first direction. For example, in one embodiment, please refer to 3. Figure 6 and Figure 8 The guide member 44 is a hollow cylindrical structure. The rotating member 41 is rotatably disposed on the inner circumferential side of the guide member 44. The sliding member 42 is a hollow cylindrical structure adapted to the outer circumferential contour of the guide member 44. One end of the guide member 44 along the X direction is fixed to the drive assembly 60, and the sliding member 42 is slidably disposed on the outer circumferential side of the guide member 44 via the other end of the guide member 44 along the X direction. The outer circumferential contour of the guide member 44 is not particularly limited, and can be, for example, an approximately hexagonal shape as shown in the figure.

[0044] In other embodiments, the first drive unit 40 may also employ a cam mechanism for transmission, where the rotational motion of the cam drives the cam follower to perform linear reciprocating sliding. Adjusting the specific shape of the cam can also adjust the motion trajectory of the cam follower. The first drive unit 40 may also employ a gear and rack mechanism for transmission, where the rotation of the gear drives the meshing rack to perform linear motion, and the rotational motion of the gear is converted into the linear motion of the rack through the meshing of the teeth. The first drive unit 40 may also employ a crank-slider mechanism or other transmission mechanisms, which will not be elaborated further here.

[0045] In one embodiment, the second drive unit 50 drives the first massage unit 21 and the second massage unit 22 to move towards or away from each other in a sliding or oscillating manner. Exemplarily, in one embodiment, the second drive unit 50 includes a connector 51 and a transmission assembly 52 fixedly engaged with the connector 51 in a first direction; the connector 51 is fixedly connected to the slider 42, and the transmission assembly 52 connects the rotating member 41 and the massage unit 20 respectively. The transmission assembly 52 is configured to convert the rotation of the rotating member 41 around an axis extending in the first direction into oscillation of the first massage unit 21 and the second massage unit 22 relative to the connector 51 in a plane perpendicular to the first direction. In other words, the second drive unit 50 is connected to the slider 42 via the connector 51. The slider 42 can drive the second drive unit 50 to achieve linear reciprocating sliding in the first direction. The transmission component 52 is disposed on the connector 51 and is connected to the massage unit 20 and the rotating component 41 respectively, so as to convert the rotation of the rotating component 41 around the axis extending in the X direction into the reciprocating oscillation of the first massage unit 21 and the second massage unit 22 in the Y direction, which moves closer or further away from each other, thereby achieving a pinching action on the massaged part within the massage space 10. This pinching action can continuously adjust the size of the massage space 10, producing a continuous pinching rhythm, which can simulate the natural feel of a real massage, promote blood circulation in the massaged part, and make the experience more comfortable.

[0046] In one embodiment, please refer to Figure 8 and Figure 9 The connector 51 includes two connecting rods 511 extending along a first direction and arranged parallel to each other at intervals, and a housing 512. The two ends of the two connecting rods 511 in the first direction are respectively connected to the housing 512 and the sliding member 42. Specifically, the two connecting rods 511 are arranged relatively parallel to each other along the Y direction, and the housing 512 is approximately a hollow hexahedral structure, with at least a portion of the transmission component 52 housed within the housing 512. The housing 512 provides structural support for the normal operation of the internal transmission component 52. In the X direction, one end of each connecting rod 511 is connected to the housing 512, and the ends away from the housing 512 are fixedly engaged with the sliding member 42 through a hole-shaft insertion method. For example, in one embodiment, please refer to... Figure 8Each connecting rod 511 has a fixing hole 515 extending in the Y direction at its end away from the housing 512 in the X direction. The sliding member 42 has two fixing posts 421 extending outward in the Y direction on both sides, and the two fixing posts 421 pass through the fixing holes 515 of the two connecting rods 511 respectively. In other embodiments, the fixing posts 421 can also be provided on the connecting rods 511, and the corresponding fixing holes 515 can also be provided on the sliding member 42; further details will not be provided here.

[0047] In one embodiment, the transmission assembly 52 includes a sliding member 53, one end of which is fixedly engaged with the connecting member 51 in the first direction and rotatably engaged in the circumferential direction. That is, the sliding member 53 can slide synchronously with the connecting member 51 in the first direction and can rotate circumferentially relative to the connecting member 51 about a rotation axis extending in the first direction.

[0048] In one embodiment, the other end of the sliding member 53 in the first direction is slidably engaged with the rotating member 41 in the first direction, and fixedly engaged in the circumferential direction. That is, the sliding member 53 can slide relative to the rotating member 41 in the first direction and can rotate synchronously with the rotating member 41 in the circumferential direction about a rotation axis extending in the first direction. Specifically, the rotating member 41 is fitted around the sliding member 53. The manner in which the rotating member 41 is fitted around the sliding member 53 is not particularly limited. In one embodiment, one of the sliding member 53 and the rotating member 41 is provided with a guide post 533, and the other is provided with a guide hole 412. The guide post 533 is slidably embedded in the guide hole 412 along the first direction. That is, when the sliding member 53 is provided with a guide post 533, the rotating member 41 is provided with a guide hole 412 adapted to the sliding member 53; when the sliding member 53 is provided with a guide hole 412, the rotating member 41 is provided with a guide post 533 adapted to the sliding member 53. For example, in one embodiment, please refer to Figure 3 , Figure 6 and Figure 9 The sliding member 53 has a guide post 533 extending in the X direction at one end, and the rotating member 41 has a guide hole 412. The guide post 533 is embedded in the guide hole 412 in the X direction. The guide post 533 can be a polygonal prism or a column of other shapes that can transmit torque.

[0049] In one embodiment, the first massage portion 21 and the second massage portion 22 are rotatably connected to the connector 51. For an example, please refer to... Figure 3 and Figure 9The transmission assembly 52 further includes a first pivot 56 and a second pivot 57 extending along a first direction and arranged parallel to each other at intervals. The first massage portion 21 and the second massage portion 22 are respectively connected to the first pivot 56 and the second pivot 57, and are fixed relative to the first pivot 56 and the second pivot 57 in a plane perpendicular to the first direction. Specifically, the first pivot 56 is connected between the first connecting end 212 and the first massage end 213 of the first massage portion 21, that is, the first pivot 56 is approximately connected to the middle of the first massage portion 21; the second pivot 57 is connected between the second connecting end 222 and the second massage end 223 of the second massage portion 22, that is, the first pivot 56 is approximately connected to the middle of the first massage portion 21. Optionally, the first massage part 21 and the second massage part 22 are rotatably engaged with the first pivot 56 and the second pivot 57, respectively, and both the first pivot 56 and the second pivot 57 are fixedly engaged with the housing 512; or, the first massage part 21 and the second massage part 22 are fixedly engaged with the first pivot 56 and the second pivot 57, respectively, and the first pivot 56 and the second pivot 57 are rotatably engaged with the housing 512; or, the first massage part 21 and the second massage part 22 are rotatably engaged with the first pivot 56 and the second pivot 57, respectively, and the first pivot 56 and the second pivot 57 are also rotatably engaged with the housing 512. With this configuration, the first massage part 21 and the second massage part 22 will swing relative to the housing 512 in the YZ plane, either facing each other or facing away from each other, with the extension direction (X direction) of the first pivot 56 and the second pivot 57 as the axis of rotation.

[0050] In one embodiment, the transmission assembly 52 further includes a slider 54. An eccentric wheel 531 is provided at one end of the sliding member 53 away from the rotating member 41 in a first direction. A shaft 532 extends outward from the eccentric wheel 531, and the shaft 532 is eccentrically arranged relative to the rotation axis of the eccentric wheel 531. The slider 54 is provided with a groove 541, and the shaft 532 is movably inserted into the groove 541. One end of the first massage portion 21 and one end of the second massage portion 22 are respectively movably connected to the slider 54. That is, the eccentric wheel 531 also includes a shaft 532, and both the first connecting end 212 and the second connecting end 222 are connected to the slider 54 and move together with the slider 54. For example, in one embodiment, please refer to... Figure 9The transmission assembly 52 also includes a pair of guide rails 55 extending perpendicular to the X direction and spaced parallel to each other in the Z direction. The slider 54 is slidably mounted on the pair of guide rails 55. The Z direction is perpendicular to both the X and Y directions. The pair of guide rails 55 are fixedly connected to the housing 512 to guide the sliding direction of the slider 54. The rotation of the sliding member 53 about its axis of rotation extending in the X direction can drive the shaft 532 on the eccentric wheel 531 to revolve relative to the axis of rotation of the sliding member 53. The shaft 532 extends in the X direction and is slidably inserted into the groove 541 extending in the Z direction. When the eccentric wheel 531 rotates, the shaft 532 will slide in the groove 541 and drive the slider 54 to perform linear reciprocating motion on the pair of guide rails 55 extending in the Z direction.

[0051] In one embodiment, please participate Figure 3 , Figure 6 and Figure 9 The slider 54 has sliding rods 542 extending along a first direction. The first connecting end 212 has a first groove 211, and the second connecting end 222 has a second groove 221. The sliding rods 542 are slidably inserted into the first groove 211 and the second groove 221 along the first direction. That is, when the slider 54 slides along the Z direction, the sliding rods 542 will slide in the first groove 211 and the second groove 221 respectively, thereby causing the first connecting end 212 and the second connecting end 222 to swing around the first pivot 56 and the second pivot 57 respectively. The swinging of the first connecting end 212 and the second connecting end 222 will also cause the first massage end 213 and the second massage end 223 to swing towards or away from each other relative to the box 512 in the YZ plane.

[0052] In one embodiment, please participate Figure 3 , Figure 6 and Figure 9The eccentric wheel 531, shaft 532, slider 54, slide rod 542, a pair of guide rails 55, first pivot 56, and second pivot 57 are all housed within the housing 512.

A mounting opening 513 is formed on the side of the housing 512 perpendicular to the first direction, allowing the massage unit 20 to extend from the housing 512 into the massage space 10. Specifically, the first connecting end 212 and the second connecting end 222 are housed within the housing 512. The first massage end 213 and the second massage end 223 extend into the massage space 10 through the mounting opening 513 on the Z-direction side. The sliding member 53 is partially housed within the housing 512. A transmission opening 514 is formed on the side of the housing 512 in the first direction, allowing the sliding member 53 to extend from the housing 512 and connect to the rotating member 41. Specifically, one end of the sliding member 53 with the eccentric wheel 531 is located inside the housing 512.
