[0036] Eccentric wheel 202 refers to an eccentric cam, specifically meaning that the center of eccentric wheel 202 is not at the point of rotation; eccentric wheel 202 can rotate around an axis on the massage housing 201.

[0037] The driving component 203 refers to the component used to provide rotational power to the eccentric wheel 202; the driving component 203 includes, but is not limited to, a motor;

[0038] The swing ring 204 is a ring-shaped component that is sleeved on the eccentric wheel 202 and can swing under the drive of the eccentric wheel 202; the shape and size of the swing ring 204 match the shape and size of the eccentric wheel 202, so that the swing ring 204 can be just sleeved on the eccentric wheel 202 and has a clearance fit with the eccentric wheel 202.

[0039] The first swing rod 205, the second swing rod 206, and the third swing rod 207 are rods used for transmitting power. The first swing rod 205 is connected to the swing ring 204 shaft, that is, the first swing rod 205 can rotate around the shaft under the drive of the swing ring 204, thus swinging. The second swing rod 206 is connected to the first swing rod 205 shaft, that is, the second swing rod 206 can rotate around the shaft under the drive of the first swing rod 205, thus swinging. The third swing rod 207 is connected to the second swing rod 206 shaft, that is, the third swing rod 207 can rotate around the shaft under the drive of the second swing rod 206. At the same time, the third swing rod 207 is connected to the eccentric wheel 202 shaft, that is, the third swing rod 207 swings under the drive of the second swing rod 206 and the eccentric wheel 202.

[0040] The back massage structure 209 refers to a structure used for massaging the back; the back massage structure 209 includes, but is not limited to, a massage head with protrusions; the back massage structure 209 is connected to the second swing rod 206 and the third swing rod 207, so that the second swing rod 206 and the third swing rod 207 drive the back massage structure 209 to swing, thereby realizing the massage of the back massage structure 209.

[0041] The first swing arm 205 is provided with a first swing arm groove 2051, which extends along the length of the first swing arm 205; the second swing arm 206 is provided with a second swing arm groove 2061, which extends along the length of the second swing arm 206; the massage housing 201 is provided with a first limiting member 2011 slidably connected to the first swing arm groove 2051 and a second limiting member 2012 slidably connected to the second swing arm groove 2061; the driving member 203 drives the eccentric wheel 202 to rotate, the eccentric wheel 202 drives the swing ring 204 to rotate eccentrically, the swing ring 204 drives the first swing arm 205, the second swing arm 206 and the third swing arm 207 to swing, the second swing arm 206 and the third swing arm 207 drive the back massage structure 209 to move along the groove length of the back massage structure groove 2010, thereby performing a massage action.

[0042] By adopting the above technical solution, the cooperation of the eccentric wheel 202, the first swing rod 205, the second swing rod 206 and the third swing rod 207 enables the back massage structure 209 to perform massage movements along a preset direction. At the same time, the drive unit 203 simultaneously drives multiple other massage structures, improving the correlation with other massage structures and enabling the massage component 200 to adapt to different massage modes.

[0043] By adopting the above technical solution, the cooperation of the eccentric wheel, the first swing rod, the second swing rod, and the third swing rod enables the back massage structure to perform massage movements along a preset direction. The linkage of multiple swing rods enables the massage trajectory of the back massage structure to adapt to the human body, improving the degree of cooperation between the back massage structure and the human body and enhancing the user's massage experience.

[0044] In other embodiments, the drive member 203 can also be used to drive the shoulder massage structure, neck massage structure and back massage structure 209 to perform massage actions synchronously. Specifically, the shoulder massage structure, neck massage structure and back massage structure 209 share a drive member 203, that is, the drive member 203 synchronously drives multiple massage structures through a transmission structure, so that the multiple massage structures are associated to adapt to different massage modes.

[0045] Please refer to the following: Figure 3 and Figure 4 In one embodiment, the third swing rod 207 is provided with a third swing rod groove 2071, the second swing rod 206 is provided with a fourth swing rod groove 2062, and the back massage structure 209 includes a back massage structure body 2091 and a back massage structure shaft 2092 connected to the back massage structure body 2091. The back massage structure shaft 2092 is slidably connected to the third swing rod groove 2071 and the fourth swing rod groove 2062. The back massage structure shaft 2092 slides in the third swing rod groove 2071 and the fourth swing rod groove 2062 when the second swing rod 206 and the third swing rod 207 swing.

[0046] Here, it can be understood that the back massage structure 209 includes a back massage structure body 2091 and a back massage structure shaft 2092. The back massage structure shaft 2092 is connected to the back massage structure body 2091. The back massage structure body 2091 is inserted into the back massage structure slide groove 2010 and is in clearance fit with the back massage structure slide groove 2010, so that the back massage structure body 2091 can slide in the back massage structure slide groove 2010. At the same time, the back massage structure shaft 2092 is inserted into the third swing rod slide groove 2071 and the fourth swing rod slide groove 2062 and is slidably connected with the third swing rod slide groove 2071 and the fourth swing rod slide groove 2062. In this way, the back massage structure shaft 2092 slides in the third swing rod slide groove 2071 and the fourth swing rod slide groove 2062 when the second swing rod 206 and the third swing rod 207 swing.

[0047] By adopting the above technical solution, the second swing rod 206 and the third swing rod 207 drive the back massage structure 209 to swing, thereby realizing the massage action of the back massage structure 209.

[0048] In one embodiment, a rack 2072 is provided on the groove wall of the third swing rod slide 2071, and a gear 2093 that meshes with the rack 2072 is provided on the back massage structure shaft 2092; the gear 2093 rotates when the rack 2072 moves relative to the gear 2093 to drive the back massage structure 209 to rotate around its own axis.

[0049] Here, it can be understood that rack 2072 refers to multiple teeth arranged along a straight line on a strip-shaped component. Gear 2093 matches rack 2072 and meshes with it. Rack 2072 is located on the groove wall of third swing rod slide 2071, and gear 2093 is located on back massage structure shaft 2092. Gear 2093 and back massage structure shaft 2092 are coaxially arranged. When gear 2093 and rack 2072 move relative to each other, rack 2072 drives gear 2093 to rotate, which in turn drives back massage structure shaft 2092 to rotate, and finally drives back massage structure body 2091 to rotate to realize the massage action of rotating back massage.

[0050] By adopting the above technical solution, the back massage structure 209 can rotate while swinging. When the back massage structure 209 swings but does not rotate, it provides a back-and-forth sliding massage experience. When the back massage structure 209 swings and rotates, it can reduce the stiffness of the back massage structure 209's back-and-forth sliding motion and improve the massage experience.

[0051] In one embodiment, the massage assembly 200 includes a lubricating pad 210 disposed on at least one side of the gear 2093 in the axial direction; the lubricating pad 210 is disposed between the second swing arm 206 and the third swing arm 207.

[0052] Here, it can be understood that the lubricating pad 210 can reduce the friction when the two parts come into contact; the gear 2093 has a lubricating pad 210 on at least one side of its own axial direction, so as to improve the smoothness of the rotation of the gear 2093; similarly, a lubricating pad 210 is provided between the second swing rod 206 and the third swing rod 207, so as to improve the smoothness of the rotation of the second swing rod 206 and the third swing rod 207.

[0053] By adopting the above technical solution, the massage component 200 can operate smoothly when performing massage actions.

[0054] In one embodiment, the back massage structure shaft 2092 is provided with a back massage structure sleeve 211, and the back massage structure body 2091 is partially disposed inside the back massage structure sleeve 211. An elastic element 212 is provided inside the back massage structure sleeve 211, one end of the elastic element 212 abuts against the back massage structure shaft 2092, and the other end of the elastic element 212 abuts against the back massage structure body 2091.

[0055] Here, it can be understood that the back massage structure shaft 2092 part is provided with a back massage structure sleeve 211, and the back massage structure sleeve 211 is provided with an elastic element 212 inside. The elastic element 212 is used to provide elastic force that allows the back massage structure body 2091 to be adjusted along the axial direction of the back massage structure sleeve 211.

[0056] By adopting the above technical solution, the back massage structure body 2091 maintains the tendency to extend out of the back massage structure sleeve 211 under the drive of the elastic element 212, so that the internal massage structure body can fit closely to the user's back when sliding on the human body, avoiding excessive local friction, balancing the massage intensity throughout the massage process, and improving the massage experience.

[0057] In one embodiment, the back massage structure sleeve 211 is provided with a limiting groove 2111, the groove length direction of the limiting groove 2111 is parallel to the back massage structure sleeve 211, and the back massage structure body 2091 is provided with a limiting block 2094 that is slidably connected to the limiting groove 2111. The limiting groove 2111 is used to guide the limiting block 2094 to move along the groove length direction.

[0058] Here, it can be understood that the limiting groove 2111 refers to the groove structure used to guide the movement of the back massage structure body 209; the limiting groove 2111 is provided on the back massage structure sleeve 211, and the groove length direction of the limiting groove 2111 is parallel to the back massage structure sleeve 211. In this way, the limiting groove 2111 guides the back massage structure body 2091 to move along the elastic force direction of the elastic member 212. The back massage structure body 2091 is provided with a limiting block 2094, and the limiting block 2094 can move along the groove length direction of the limiting groove 2111.

[0059] It needs further explanation that the limiting block 2094 is designed for easy installation. The limiting block 2094 is elastic; during installation, its contraction allows it to be inserted into the back massage structure sleeve 211. When moved to the position of the limiting groove 2111, the limiting block 2094 opens to engage with it, thus preventing the back massage structure body 2091 from detaching from the back massage structure sleeve 2111. Therefore, this design prevents the back massage structure body 2091 from detaching and restricts its rotation; that is, the back massage structure body 2091 cannot rotate within the sleeve.

[0060] By adopting the above technical solution, it is convenient to install the back massage structure body 2091 while preventing the back massage structure body 2091 from falling off.

[0061] In one embodiment, the back massage structure sleeve 211 is provided with a plurality of limiting grooves 2111 arranged along its circumference, and the back massage structure body 2091 is provided with limiting blocks 2094 that are slidably disposed in the limiting grooves 2111.

[0062] Here, it can be understood that the design of the limiting block 2094 serves two purposes: firstly, it facilitates installation and prevents the back massage structure body 2091 from detaching from the back massage structure sleeve 211. Secondly, this design ensures that during the rotation of the back massage structure body 2091 around its axis, the back massage structure body 2091 and the back massage structure sleeve 211 rotate completely synchronously without relative movement. This ensures that the rotation of the back massage structure body 2091 is effective, because in actual use, the end of the back massage structure body 2091 is under stress. If completely synchronous rotation is not ensured, the back massage structure sleeve 211 may rotate while the back massage structure body 2091 does not, thus diminishing the massage effect. Therefore, this improves the effectiveness of the massage action. By adopting the above technical solution, the effectiveness and reliability of the back massage structure body 2091 during massage are improved.

[0063] In one embodiment, the swing ring 204 extends radially and is provided with two transmission arms 2041. The two transmission arms 2041 are spaced apart in the circumferential direction of the swing ring 204. One transmission arm 2041 is axially connected to the first swing rod 205, and the other transmission arm 2041 is axially connected to the third swing rod 207.

[0064] By adopting the above technical solution, the torque of the swing ring 204 is increased, making it easier for the swing ring 204 to drive the first swing rod 205 and the third swing rod 207 to swing.

[0065] In one embodiment, the massage component 200 further includes a transmission gear 213 fixedly connected to the eccentric wheel 202. The transmission gear 213 is disposed together with the eccentric wheel 202 and is connected to the drive component 203 for transmission.

[0066] Here, it can be understood that the transmission gear 213 and the eccentric wheel 202 are coaxially and fixedly connected.

[0067] By adopting the above technical solution, the drive component 203 and the eccentric wheel 202 are connected by a transmission gear 213, which facilitates the power transmission of the drive component 203.

[0068] Secondly, a massager 10 is provided, including a massager main unit and the aforementioned massage component 200, wherein the massage component 200 is disposed on the massager main unit.

[0069] By adopting the above technical solution, based on the advantages of the massage component 200 in the above embodiment, the massager in this embodiment also has the advantages of multiple massage structures sharing one drive unit 203, having a small number of drive units 203 and occupying little internal space.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
