[0041] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0042] like Figure 1-5As shown, a highly efficient transmission and compact massage movement drive mechanism is applied to massage devices such as massage beds and massagers. The massage movement drive mechanism includes a massage wheel assembly 10, an eccentric driver 20, a gear set 21, a gear shaft 22, a shaft coupling support seat 50, a shaft coupling support plate 51, a slide rail 60 and a plurality of travel shafts 61. The slide rail 60 is extended in the massage direction of the massage device, and travel wheels 62 are arranged at both ends of the plurality of travel shafts 61. The travel shafts 61 are mounted on the slide rail 60 through the travel wheels 62 and reciprocate on the slide rail 60.

[0043] The coupling support plate 51 is installed in the middle of several traveling shafts 61, at least two coupling support seats 50 are arranged, an assembly groove is arranged at the bottom of the coupling support seat 50 and is installed on the traveling wheels 62 at both ends of the traveling shaft 61 through the assembly groove, and the two coupling support seats 50 are correspondingly installed at both ends of the traveling shaft 61, so that the coupling support plate 51 and the coupling support seat 50 are movably installed on the slide rail 60 through the traveling shaft 61.

[0044] The eccentric driver 20 preferably adopts a motor. The eccentric driver 20 is installed on the shaft support seat 50. A gear installation cavity 502 is provided on one side of the shaft support seat 50. The gear set 21 is provided with a driving gear 211 and a driven gear 212. The driving gear 211 and the driven gear 212 are installed in the gear installation cavity 502 in a vertical direction. After the eccentric driver 20 is installed on the shaft support seat 50, its output end is connected to the driving gear 211, and the driving gear 211 drives and meshes with the driven gear 212, so that the eccentric driver 20 drives the driven gear 212 by driving the driving gear 211, and the driven gear 212 is in turn connected to one end of the gear shaft 22, so that the driven gear 212 drives the gear shaft 22 to rotate.

[0045] Therefore, by setting a gear installation cavity 502 on the side of the coupling support seat 50, the driving gear 211 and the driven gear 212 are installed in the vertical direction, so as to achieve the purpose of compact installation of the gear set 21, and the eccentric driver 20 is installed on one side of the coupling support seat 50, so that the eccentric driver 20 can drive and control the gear set 21 on the coupling support seat 50, further reducing the size of the whole machine and facilitating disassembly and assembly.

[0046] The two ends of the gear shaft 22 are movably connected to the shaft support seat 50 through bearings, and the middle part of the gear shaft 22 is movably connected to the shaft support plate 51 through bearings. An eccentric piece 23 is arranged in the hole of the massage wheel assembly 10. The eccentric piece 23 arranged in the present application can be an eccentric wheel and an eccentric shaft, and the massage wheel assembly 10 is arranged in the length direction of the gear shaft 22 through the eccentric piece 23. In actual use, the eccentric piece 23 is fixedly connected to the gear shaft 22, and the massage wheel assembly 10 is movably installed on the eccentric piece 23, so a plurality of massage wheel assemblies 10 can be arranged on the gear shaft 22.

[0047] After the eccentric driver 20 is started, the gear shaft 22 is driven to rotate through the gear set 21. When the gear shaft 22 rotates, the eccentric piece 23 is driven, so that the massage wheel assembly 10 performs a hammering massage action in the radial direction of the gear shaft 22 under the eccentric rotation of the eccentric piece 23. The massage wheel assembly 10 performs a hammering massage on the human body while sliding on the slide rail 60.

[0048] In this way, when the present application starts the eccentric driver 20 to drive the gear set 21 and the transmission gear shaft 22, the massage wheel assembly 10 can be eccentrically rotated in the radial direction of the rotating gear shaft 22 according to the eccentric assembly of the massage wheel assembly 10 through the eccentric member 23, thereby achieving the effect of beating and massaging the human body. Compared with the weak beating and massage effect previously achieved by relying on motor vibration, the present application drives the beating and massage action of the massage wheel assembly 10 through the eccentric driver 20, which can not only achieve independent control of the beating and massage of the massage wheel assembly 10, and facilitate adjustment of the beating and massage action intensity of the massage wheel assembly 10, but also can combine the efficient and stable transmission mode of the gear set 21 to improve the massage action stability of the massage wheel assembly 10 and the massage experience of the user.

[0049] The massage movement driving mechanism provided in the present application also includes a limit seat 30 and a limit shaft 31. The limit seat 30 has a seat body 301 and a connecting seat end plate 302 arranged on both ends of the seat body 301, and the upper end of the connecting seat end plate 302 is higher than the seat body 301 and has an axial hole. The upper end of the connecting seat end plate 302 is fixedly connected to the massage wheel assembly 10, so that the limit seat 30 follows the massage wheel assembly 10 to move radially toward the gear shaft 22.

[0050] The seat body 301 of the limit seat 30 is provided with a limit hole 3011, the limit shaft 31 is arranged parallel to the gear shaft 22, both ends of the limit shaft 31 are connected to the shaft connecting support seat 50 through bearings, the middle part of the limit shaft 31 is connected to the shaft connecting support plate 51, and the limit shaft 31 is also passed through the limit hole 3011 of the limit seat 30.

[0051] The hole shape of the limiting hole 3011 of the seat body 301 is set to be strip-shaped, so that when the limiting seat 30 follows the movement of the massage wheel assembly 10, the limiting seat 30 can move according to the hole length range of the limiting hole 3011. Since the limiting seat 30 is fixedly connected to the massage wheel assembly 10, the movement range of the massage wheel assembly 10 is limited by the movement range of the limiting hole 3011 of the limiting seat 30 on the limiting shaft 31, thereby controlling the beating massage movement amplitude of the wheel assembly. In the embodiment of the present application, the limiting hole 3011 set in the limiting seat 30 is preferably set to 0-10mm for the beating massage movement amplitude of the massage wheel assembly 10.

[0052] Thus, the seat body 301 of the present application is provided with a limiting hole 3011 for the limiting shaft 31 to pass through the limiting hole 3011. When the eccentric driver 20 drives the massage wheel assembly 10, the limiting seat 30 is driven synchronously, and the range of motion of the limiting hole 3011 on the limiting shaft 31 is used to limit the movement of the limiting seat 30 and control the amplitude of the beating massage movement of the massage wheel assembly 10. This facilitates the user to control the amplitude of the beating massage of the massage wheel assembly 10, and solves the problem of difficulty in controlling the amplitude of the beating massage driven by the vibration frequency of the motor.

[0053] The massage movement driving mechanism provided in the present application also includes a translation driver 40 and a screw rod 41. The translation driver 40 preferably adopts a motor. The translation driver 40 is installed on the coupling support seat 50 at the other end of the gear shaft 22. The screw rod 41 is arranged parallel to the gear set 21. The two ends of the screw rod 41 are connected to the coupling support seat 50 through bearings, and the middle part of the screw rod 41 is connected to the coupling support plate 51 through a bearing.

[0054] Therefore, the gear shaft 22 and the screw rod 41 are movably mounted on the coupling support seat 50 and the coupling support plate 51, and the coupling support seat 50 and the coupling support plate 51 are mounted on the traveling shaft 61, and both ends of the traveling shaft 61 slide back and forth on the slide rail 60 through the traveling wheels 62, thereby driving the massage wheel assembly 10 to slide back and forth along the direction of the slide rail 60 and simultaneously performing hammering and kneading massage actions on the human body.

[0055] The output end of the translation driver 40 is connected to one end of the screw rod 41, so that the translation driver 40 drives the screw rod 41 to rotate after it is started. The left and right sections of the screw rod 41 are provided with threads with opposite rotation directions. The threads of the left and right sections of the screw rod 41 are movably sleeved with nut sleeves 42. The two ends of the nut sleeves 42 are provided with sleeve connecting plates 43 and are fixedly connected to the limit seat 30 through the sleeve connecting plates 43. Therefore, after the translation driver 40 is started, the translation driver 40 drives the screw rod 41 to rotate, so that the nut sleeves 42 of the left and right sections of the screw rod 41 slide on the screw rod 41, and the nut sleeves 42 synchronously drive the limit seat 30 and the massage wheel assembly 10 when sliding.

[0056] The massage wheel assembly 10 of the present application includes a first massage wheel group 101 and a second massage wheel group 102, and the first massage wheel group 101 and the second massage wheel group 102 are both provided with two main massage wheels 103. The first massage wheel group 101 and the second massage wheel group 102 are both fixedly connected to the limit seat 30 and the nut sleeve 42 respectively fixedly connected to the left and right sections of the screw rod 41 through the limit seat 30, so that after starting the translation driver 40, the translation driver 40 drives the screw rod 41 to rotate, thereby controlling the first massage wheel group 101 and the second massage wheel group 102 to move toward or in the opposite direction in the axial direction of the screw rod 41 to perform a kneading massage action.

[0057] In this way, the present application provides threads with opposite rotation directions on the left and right sections of the screw rod 41, and correspondingly installs the first massage wheel group 101 and the second massage wheel group 102 on the nut sleeves 42 on the left and right sections of the screw rod 41. When the screw rod 41 is driven to rotate by the translation driver 40, the first massage wheel group 101 and the second massage wheel group 102 can move toward or in the opposite direction in the axial direction of the screw rod 41 to perform a kneading massage action.

[0058] Compared with the previous implementation method that multiple groups of massage wheels can only move in the same direction for kneading massage, the kneading massage area of ​​the massage wheel assembly 10 on the human body can be increased, the massage action mode of the massage wheel assembly 10 can be increased, the diversified massage needs of users can be met, and the purpose of humanized design can be achieved. In addition, the first massage wheel assembly 101 and the second massage wheel assembly 102 are respectively assembled in the length direction of the screw rod 41 through the limit seat 30 and the nut sleeve, the structure is simple and compact, and it is easy to disassemble and assemble, and the size of the whole machine is reduced in two dimensions in the horizontal direction and the vertical direction.

[0059] The surface of the main massage wheel 103 is provided with a plurality of massage convex portions 1031, which are formed by the surface of the main massage wheel 103 protruding outwards in an integrated manner, and the massage convex portions 1031 are roughly semicircular or semi-ellipsoidal. A massage wheel sleeve 104 is provided in the hole of each main massage wheel 103, and the main massage wheel 103 is movably assembled with the eccentric member 23 through the massage wheel sleeve 104, so that the main massage wheel 103 is installed on the gear shaft 22 through the eccentric member 23, and the main massage wheel 103 is also fixedly connected to the nut sleeve seat 42 on the screw rod 41 through the limit seat 30. In this way, by providing a plurality of massage convex portions 1031 on the surface of the main massage wheel 103, when the main massage wheel 103 contacts the human body for beating and kneading massage, the massage convex portions 1031 on the surface of the main massage wheel 103 are used to massage the human body, which can match the concave and convex structure of the human body and improve the massage effect.

[0060] An arc-shaped mounting groove 501 is arranged at the upper edge of the coupling support seat 50, and a plurality of buffering massage wheels 80 are movably arranged along the arc-shaped mounting groove 501. When the user is massaging, the buffering massage wheels 80 support part of the user's body, thereby increasing the force-bearing area of ​​the user's body on the massage device, buffering the body support pressure, and improving the user's massage experience.

[0061] The massage movement driving mechanism provided in the present application also includes a first neck massage wheel 70, a second neck massage wheel 71 and an auxiliary massage wheel 81, wherein both ends of the first neck massage wheel 70, the second neck massage wheel 71 and the auxiliary massage wheel 81 are connected to a bracket 72, and the second neck massage wheel 71 is arranged on the walking shaft 61 and one end of the connecting shaft support plate 51 through the bracket 72, so as to support and massage the user's cervical spine.

In addition, a support pulley 74 and a telescopic spring 75 are set on the walking shaft 61 and the other end of the connecting shaft support plate 51. The bottom of the hinge plate 73 is supported on the support pulley 74, so that the hinge plate 73 reduces the friction when the connection point of the gear shaft 22 is used as a fulcrum for turning. The bracket 72 of the first neck massage wheel 70 is fixedly connected to the telescopic spring 75. The telescopic spring 75 is set to provide elastic force for the turning action of the first neck massage wheel 70, so as to perform elastic massage action on the user's cervical vertebrae. Under the elastic action of the telescopic spring, the first neck massage wheel 70 can be elastically lifted upward by about 30 mm, thereby performing peristaltic massage on the cervical vertebrae of the human body.
