[0022] To better understand the technical solution of this application, the oscillating pressing mechanism and massage device of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementation methods can be combined with each other.

[0023] Figure 1 The figure shown is a perspective view of the oscillating pressing mechanism 10 according to an embodiment of this application. Figure 2 As shown Figure 1 A three-dimensional schematic diagram of the oscillating pressing mechanism 10 after removing part of the housing 11; Figure 3 As shown Figure 1 A partial three-dimensional sectional view of the oscillating pressing mechanism 10 shown. (Participate) Figures 1 to 3As shown, this application provides a swing-type pressing mechanism 10, which includes a housing 11, a power transmission assembly 12, and an output arm 13.

[0024] The power transmission assembly 12 is housed within the housing 11. The housing 11 serves to protect the power transmission assembly 12. The power transmission assembly 12 includes a drive structure 14 and a connecting rod structure 15. The first end of the connecting rod structure 15 is connected to the drive structure 14, and the second end of the connecting rod structure 15 is movably disposed within the housing 11.

[0025] The first end of the output arm 13 is movably disposed on the housing 11 and has at least three degrees of freedom with respect to the housing 11. The second end of the output arm 13 extends beyond the housing 11 and is used to connect to the massage head. The second end of the connecting rod structure 15 is sleeved on the outside of the output arm 13, and the output arm 13 and the connecting rod structure 15 have two degrees of freedom. The second end of the connecting rod structure 15 can be sleeved on the outside of the middle portion of the output arm 13. Thus, the output arm 13 and the connecting rod structure 15 can be movably connected, allowing the output arm 13 to move via the connecting rod structure 15. The shape of the output arm 13 can be cylindrical or any other arbitrary combination of shapes; this application does not impose any limitations.

[0026] The drive structure 14 is used to cause the output arm 13 to reciprocate and oscillate via the linkage structure 15. Thus, the reciprocating and oscillating motion of the output arm 13 can be achieved solely through the linkage structure 15, thereby enabling the output arm 13 to reciprocate and oscillate for pressing. This simplifies the structure of the power transmission component 12 for the reciprocating and oscillating motion of the output arm 13, facilitating the miniaturization of the oscillating pressing mechanism 10.

[0027] In one embodiment, the power transmission assembly 12 further includes an eccentric gear 16, and a drive structure 14 is connected to the eccentric gear 16. The eccentric gear 16 includes a gear body 17 and an eccentric protrusion 18 disposed on the end face of the gear body 17, and the first end of the connecting rod structure 15 is connected to the eccentric protrusion 18. The first end of the connecting rod structure 15 can be sleeved on the outside of the eccentric protrusion 18 and connected to the eccentric protrusion 18 via a bearing. The drive structure 14 is used to drive the eccentric gear 16 to rotate, so that the output arm 13 reciprocates and oscillates via the connecting rod structure 15. Thus, the structure for realizing the reciprocating and oscillating motion of the output arm 13 is simple.

[0028] In one embodiment, the drive structure 14 can be directly connected to the eccentric gear 16.

[0029] In another embodiment, the power transmission assembly 12 further includes a transmission structure 19 connected between the drive structure 14 and the eccentric gear 16. The drive structure 14 can be an electric motor. The transmission structure 19 includes a gear set 20 and a worm 21. The drive structure 14 is connected to the worm 21, the worm 21 is engaged with the gear set 20, and the gear set 20 is engaged with the eccentric gear 16. Specifically, the worm 21 is engaged with the gear set 20, meaning that the teeth of the worm 21 mesh with the teeth of the gear set 20. Similarly, the gear set 20 is engaged with the eccentric gear 16, meaning that the teeth of the gear set 20 mesh with the teeth of the eccentric gear 16.

[0030] The drive structure 14 drives the eccentric gear 16 to rotate via the worm gear 21 and gear set 20, thereby causing the output arm 13 to reciprocate and press via the connecting rod structure 15. Thus, the drive structure 14, through the cooperation of the worm gear 21, gear set 20, and eccentric gear 16, and via the connecting rod structure 15, causes the output arm 13 to reciprocate and swing. This makes the power transmission assembly 12 more stable and reliable.

[0031] In one embodiment, the gear set 20 includes a first gear 22 and a second gear 23 arranged in a stacked configuration (e.g., ...). Figure 3 As shown in the diagram, the end face of the first gear 22 is connected to the end face of the second gear 23 and rotates coaxially with the second gear 23. The first gear 22 may have more teeth than the second gear 23.

[0032] The drive structure 14 is connected to the worm gear 21, which is connected to the first gear 22, and the second gear 23 is connected to the eccentric gear 16. The drive structure 14 drives the eccentric gear 16 to rotate via the worm gear 21, the first gear 22, and the second gear 23, thereby causing the output arm 13 to reciprocate and oscillate via the connecting rod structure 15. This design results in a more compact structure and reduces the length of the oscillating pressing mechanism 10.

[0033] See Figure 3 As shown, in one embodiment, the first end of the output arm 13 has at least a first rotational degree of freedom, a second rotational degree of freedom, and a translational degree of freedom with respect to the housing 11. The first rotational degree of freedom is the degree of freedom to rotate about a first direction X as an axis, the second rotational degree of freedom is the degree of freedom to rotate about the extension direction of the output arm 13 as an axis, and the translational degree of freedom is the degree of freedom to move along the extension direction of the output arm 13. The extension direction of the output arm 13 can refer to the direction from the first end to the second end of the output arm 13. When the output arm 13 is cylindrical, the extension direction of the output arm 13 can refer to its axial direction. In this embodiment, the first direction X can refer to the width direction of the oscillating pressing mechanism 10. The first direction X intersects with the extension direction of the output arm 13. The extension direction of the output arm 13 can be any direction in a plane perpendicular to the first direction X.

[0034] The connection methods between the first end of the output arm 13 and the housing 11 described below are only a few implementation methods. As long as the first end of the output arm 13 and the housing 11 have at least a first rotational degree of freedom, a second rotational degree of freedom, and a translational degree of freedom, this application does not limit the specific connection method.

[0035] In one embodiment, the oscillating pressing mechanism 10 further includes a rolling bushing 24. The rolling bushing 24 is rotatably mounted on the housing 11 about a first direction X. The rolling bushing 24 has a mounting hole 25. The first end of the output arm 13 is a shaft, which can be a cylinder, and the axial direction of the shaft can coincide with the extension direction of the output arm 13. The shaft is inserted into the mounting hole 25 of the rolling bushing 24 to provide three degrees of freedom between the output arm 13 and the housing 11. The shaft being inserted into the mounting hole 25 of the rolling bushing 24 allows the output arm 13 to move along the extension direction of the mounting hole 25 and to rotate about the extension direction of the mounting hole 25. Simultaneously, since the rolling bushing 24 is rotatably mounted on the housing 11 about the first direction X, the output arm 13 can rotate about the first direction X. Thus, it is simple to achieve three degrees of freedom between the output arm 13 and the housing 11.

[0036] In one embodiment, the housing 11 includes a housing body 26 and a first fixing member 27 fixedly disposed inside the housing body 26. The first fixing member 27 can be fixedly disposed inside the housing body 26 by means of screw connection or other means, which is not limited in this application. The first fixing member 27 is provided with a receiving groove 28, and a rolling bushing 24 is disposed between the first fixing member 27 and the housing body 26 and is received within the receiving groove 28. In this way, the rolling bushing 24 can be limited by the receiving groove 28, so that the rolling bushing 24 can only rotate within the receiving groove 28, so that the rolling bushing 24 is rotatably disposed on the housing 11 about a first direction X as an axis.

[0037] Figure 4 The figure shown is a perspective view of the output arm 13 and the fixed bushing 29 of the oscillating pressing mechanism 10 according to another embodiment of this application. Figure 5 As shown Figure 4 A cross-sectional view of one embodiment of the output arm 13 and the fixed bushing 29 is shown. See also Figure 4 and Figure 5As shown, in another embodiment, the oscillating pressing mechanism 10 further includes a fixed bushing 29, which is fixedly disposed on the housing 11. The fixed bushing 29 can be fixedly disposed on the housing 11 by means of interference fit or other means. The fixed bushing 29 includes a bushing body 30 and a ball joint 31. The bushing body 30 is provided with a spherical groove 32, and the ball joint 31 is movably disposed in the spherical groove 32. The first end of the output arm 13 is a slider, which is movably disposed through the ball joint 31 along the extension direction of the output arm 13, so that the output arm 13 and the housing 11 have four degrees of freedom. In this way, the method of realizing four degrees of freedom between the output arm 13 and the housing 11 is simple.

[0038] Figure 6 As shown Figure 4 A cross-sectional view of another embodiment of the output arm 13 and the fixed bushing 29 shown. See also Figure 4 and Figure 6 As shown, in another embodiment, the fixed bushing 29 has a cylindrical hole 33. The first end of the output arm 13 is a sphere, which is movably disposed in the cylindrical hole, so that the output arm 13 and the housing 11 have four degrees of freedom. In this way, the method of realizing four degrees of freedom between the output arm 13 and the housing 11 is simple.

[0039] See you again Figure 3 and Figure 4 As shown, in one embodiment, the output arm 13 and the connecting rod structure 15 have a third rotational degree of freedom and a fourth rotational degree of freedom. The third rotational degree of freedom is the degree of freedom of rotation about a first direction X. The fourth rotational degree of freedom is the degree of freedom of rotation about a second direction Y. The first direction X is perpendicular to the second direction Y. In this embodiment, the second direction Y can refer to the length direction of the oscillating pressing mechanism 10.

[0040] The connection method between the output arm 13 and the connecting rod structure 15 described below is only one implementation method. It is sufficient to enable the output arm 13 and the connecting rod structure 15 to have a third rotational degree of freedom and a fourth rotational degree of freedom. This application does not limit the specific connection method.

[0041] In one embodiment, the oscillating pressing mechanism 10 further includes a limiting sleeve 34, which has a mating hole 35. The connecting rod structure 15 has a limiting space 36. The output arm 13 includes an arm body 37 and a rotating shaft 38 protruding from the side wall of the arm body 37. The arm body 37 extends along the extension direction of the output arm 13. The rotating shaft 38 is rotatably disposed in the mating hole 35 of the limiting sleeve 34 about a first direction X. The rotating shaft 38 can rotate about the extension direction of the mating hole 35 of the limiting sleeve 34. This arrangement provides a third rotational degree of freedom between the output arm 13 and the connecting rod structure 15.

[0042] The outer surface of the limiting sleeve 34 is arc-shaped, and it mates with the inner wall of the limiting space 36, allowing the limiting sleeve 34 to be rotatably disposed within the limiting space 36 about the second direction Y as an axis. It can be understood that the inner wall of the limiting space 36 can also be arc-shaped, and the mating of the outer surface of the limiting sleeve 34 with the inner wall of the limiting space 36 allows for relative movement between the output arm 13 and the connecting rod structure 15. This arrangement provides a fourth rotational degree of freedom between the output arm 13 and the connecting rod structure 15.

[0043] In one embodiment, the housing 11 includes a second fixing member 39 fixedly disposed inside the housing body 26. The second fixing member 39 can be fixedly disposed inside the housing body 26 by means of screw connection or other means, which is not limited in this application. The second fixing member 39 is provided with a groove 40 extending along the second direction Y. The second end of the connecting rod structure 15 is provided with a sliding part 41, wherein the sliding part 41 can be fixedly connected to the connecting rod structure 15, or it can be integrally formed with the connecting rod structure 15. The sidewall of the sliding part 41 is an arc-shaped surface, and the sliding part 41 is movably disposed in the groove 40. The sliding part 41 can reciprocate along the extension direction of the groove 40, and can also reciprocate and rotate around the rotation center of the arc-shaped surface. In this way, the second end of the connecting rod structure 15 can be movably disposed in the housing 11.

[0044] In this embodiment, the drive structure 14 can drive the worm gear 21 to rotate, and sequentially drive the eccentric gear 16 to rotate through the first gear 22 and the second gear 23. The rotation of the eccentric gear 16 can drive the connecting rod structure 15 to reciprocate, and through the connecting rod structure 15, the output arm 13 can reciprocate and swing in at least the plane containing the first direction X and the second direction Y. The output arm 13 can also reciprocate along its extension direction, thereby completing the compound action of reciprocating swing and reciprocating pressing, so that the output arm 13 reciprocates and swings.

[0045] This application provides a massage device, which can be of various types such as a neck massage device, a waist massage device, or a shoulder and neck massage device; this application is not limited to these types. The massage device includes a swaying pressing mechanism. It should be noted that the description of the swaying pressing mechanism in the above embodiments and implementation methods is also applicable to the massage device in the embodiments of this application.

[0046] In one embodiment, the massage device further includes a massage head, with the second end of the output arm extending outside the housing and connected to the massage head. This drive structure, via a linkage, causes the output arm to reciprocate and oscillate, thereby enabling the movement of the massage head and achieving the massage function of the massage device.
