With more and more people spending long hours sitting at work and in their daily lives, massage devices are commonly used to massage uncomfortable areas to eliminate or alleviate symptoms.

[0003] In related technologies, massage devices achieve massage to users through the movement of massage components, but most massage devices currently have a relatively complex structure and a complicated assembly process. Utility Model Content

[0004] In view of this, the present disclosure provides a driving component and a massage device. The massage device and driving component have a simple structure, which facilitates the assembly of the massage device and helps to reduce the manufacturing cost of the massage device.

[0005] Specifically, this disclosure is achieved through the following technical solution:

[0006] According to a first aspect of the present disclosure, a driving component is provided, comprising a rotating shaft, a driving rod, and an eccentric cam. The driving rod is tractively connected to the rotating shaft, and the driving rod is rotatable with the rotating shaft, wherein a first included angle between the driving rod and the rotating shaft is an acute angle. The driving rod includes a rod body, which is provided with a limiting member, a first limiting portion, and a second limiting portion spaced apart from the first limiting portion. The eccentric cam is mounted on the driving rod. The limiting member abuts against the eccentric cam to restrict the rotation of the eccentric cam relative to the driving rod. The eccentric cam is disposed between the first limiting portion and the second limiting portion, and abuts against both the first limiting portion and the second limiting portion respectively, to restrict the movement of the eccentric cam along the axial direction of the driving rod.

[0007] The technical solution of this disclosure will be further explained below:

[0008] In one embodiment, the eccentric cam has a first mounting groove and a limiting groove communicating with the first mounting groove. The eccentric cam is sleeved on the rod body through the first mounting groove, and the limiting member cooperates with the limiting groove to abut against the eccentric cam.

[0009] In one embodiment, the rod body is provided with a mounting hole that matches the limiting member, and the limiting member is inserted into the rod body through the mounting hole.

[0010] In one embodiment, the second limiting portion is disposed away from the rotation axis relative to the first limiting portion. The second limiting portion is detachably mounted on the rod body.

[0011] In one embodiment, the eccentric cam includes an eccentric drive portion for transmission connection with a shoulder massager.

[0012] In one embodiment, the eccentric cam is further provided with a protrusion adjacent to the eccentric drive unit, and the drive unit also includes a limiting ring fixedly connected to the eccentric cam. The limiting ring and the protrusion are spaced apart to form a limiting structure that restricts the movement of the shoulder massager along the axial direction of the eccentric cam.

[0013] In one embodiment, the drive rod is further provided with a connecting portion for rotatably connecting with the neck massager, the connecting portion being spaced apart from the eccentric cam along the axial direction of the drive rod.

[0014] In one embodiment, the connecting part includes a bearing.

[0016] According to a second aspect of the present disclosure, a massage device is provided. The massage device includes a support assembly, a massage assembly, a first drive mechanism, and a drive component as described in any of the above embodiments. The first drive mechanism is disposed on the support assembly and is used to drive a rotating shaft to rotate. At least a portion of the massage assembly is connected to an eccentric cam drive.

[0017] The technical solution of this disclosure will be further explained below:

[0018] In one embodiment, the drive rod further includes a connecting portion spaced apart from the eccentric cam along the axial direction of the drive rod, the eccentric cam including an eccentric drive portion; the massage assembly includes a shoulder massage component and a neck massage component, the shoulder massage component being drively connected to the eccentric drive portion, and the neck massage component being rotatably connected to the connecting portion.

[0019] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0020] During the assembly of this drive component, a limiting member is provided on the body of the drive rod, and an eccentric cam is installed on the drive rod, so that the limiting member abuts against the eccentric cam, thereby restricting the rotation of the eccentric cam relative to the drive rod. A first limiting part and a second limiting part are spaced apart on the rod body, and the eccentric cam is positioned between the first and second limiting parts, so that the eccentric cam abuts against the first and second limiting parts respectively, thereby restricting the movement of the eccentric cam along the axial direction of the drive rod. This drive component has a simple structure, a simple assembly process, and high overall structural reliability after assembly. When the massage device is assembled, at least a portion of the massage components are connected to the eccentric cam via a transmission. A first drive mechanism drives the rotating shaft to rotate, thereby driving the drive rod to rotate, which in turn drives the eccentric cam to rotate, causing the massage components to move and achieve massage. The limiting member, the first limiting part, and the second limiting part restrict the rotation or movement of the eccentric cam relative to the drive rod, thereby fixing the massage components to the drive rod. This massage device has a simple structure, a simple assembly process, and a robust overall structure with high reliability after assembly.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0036] Massage devices, as health care tools to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and shoulder and neck massagers. Currently, there are numerous types and brands of massage devices available, offering consumers a wide range of choices. Therefore, how to win consumer favor and enhance product competitiveness has become an increasingly important issue for massage device manufacturers.

[0037] Nowadays, people are increasingly working and living in situations where they sit for long periods of time. In order to eliminate or alleviate discomfort, people often use massage devices to massage the uncomfortable areas to relieve fatigue.

[0038] However, in related technologies, massage devices achieve massage to users through the movement of massage components, but most massage devices currently have a relatively complex structure and a complicated assembly process.

[0039] Based on this, the present disclosure provides a drive component 100 and a massage device 10. The massage device 10 and the drive component 100 have simple structures, which facilitates the assembly of the massage device 10 and helps to reduce the manufacturing cost of the massage device 10.

[0040] To better understand the drive component 100 of this disclosure, the following description is based on a massage device 10 in which the drive component 100 is applied.

[0041] like Figure 1 as well as Figure 2 As shown, in some embodiments, a massage device 10 is provided, including a drive component 100 and a massage assembly 200, wherein the drive component 100 is used to drive the massage assembly 200 to move in order to massage the user.

[0042] Combination Figures 3 to 5 As shown, the driving component 100 includes a rotating shaft 110, a driving rod 120, and an eccentric cam 130. The driving rod 120 is connected to the rotating shaft 110 and can rotate with the rotating shaft 110. The first included angle between the driving rod 120 and the rotating shaft 110 is an acute angle. The driving rod 120 includes a rod body 121, which is provided with a limiting member 140, a first limiting portion 150, and a second limiting portion 160 spaced apart from the first limiting portion 150. The eccentric cam 130 is mounted on the driving rod 120. The limiting member 140 abuts against the eccentric cam 130 to limit the rotation of the eccentric cam 130 relative to the driving rod 120. The eccentric cam 130 is disposed between the first limiting portion 150 and the second limiting portion 160, and abuts against both the first limiting portion 150 and the second limiting portion 160 respectively to limit the movement of the eccentric cam 130 along the axial direction of the driving rod 120. The massage device 10 also includes a support assembly 300 and a first drive mechanism 400, which is disposed on the support assembly 300 and is used to drive the rotating shaft 110 to rotate. At least a portion of the massage assembly 200 is connected to the eccentric cam 130 for transmission.

[0043] Combination Figures 1 to 5As shown, during the assembly of the drive component 100, a limiting member 140 is provided on the rod body 121 of the drive rod 120, and an eccentric cam 130 is installed on the drive rod 120, so that the limiting member 140 abuts against the eccentric cam 130, thereby restricting the rotation of the eccentric cam 130 relative to the drive rod 120. Furthermore, the limiting member 140 can protrude from the rod body 121 of the drive rod 120, or it can be a groove provided on the rod body 121 of the drive rod 120. A first limiting portion 150 and a second limiting portion 160 are spaced apart on the rod body 121, and the eccentric cam 130 is positioned between the first limiting portion 150 and the second limiting portion 160, so that the eccentric cam 130 abuts against the first limiting portion 150 and the second limiting portion 160 respectively, thereby restricting the movement of the eccentric cam 130 along the axial direction of the drive rod 120. This drive component 100 has a simple structure, a simple assembly process, and high overall structural reliability after assembly. When the massage device 10 is assembled, at least a portion of the massage component 200 is connected to the eccentric cam 130 via a transmission connection. A first drive mechanism 400 drives the rotating shaft 110 to rotate, thereby rotating the drive rod 120 and consequently the eccentric cam 130, causing the massage component 200 to move and perform massage. A limiting member 140, a first limiting part 150, and a second limiting part 160 restrict the rotation or movement of the eccentric cam 130 relative to the drive rod 120, thus fixing the massage component 200 to the drive rod 120. This massage device 10 has a simple structure, a simple assembly process, and a robust overall structure with high reliability after assembly.

[0044] It should be noted that the massage component 200 can massage the neck, shoulders, back, waist, hips, or legs, and can be set according to actual needs.

[0045] like Figures 3 to 5 As shown, in some embodiments, the massage assembly 200 includes a shoulder massager 210, which is drively connected to an eccentric cam 130. Thus, the shoulder massager 210 is used to massage the shoulders of the human body.

[0046] like Figure 5 as well as Figure 6As shown, in some embodiments, the eccentric cam 130 is provided with a first mounting groove 131 and a limiting groove 132 communicating with the first mounting groove 131. The eccentric cam 130 is sleeved on the rod body 121 through the first mounting groove 131, and the limiting member 140 cooperates with the limiting groove 132 to abut against the eccentric cam 130. In this way, the cooperation between the limiting member 140 and the limiting groove 132 causes the eccentric cam 130 to rotate synchronously when the drive rod 120 rotates, thereby limiting the rotation of the eccentric cam 130 relative to the drive rod 120. Under the action of the limiting member 140, the eccentric cam 130 can rotate with the drive rod 120, so that the shoulder massager 210 provided on the eccentric cam 130 can massage the user.

[0047] like Figure 7 As shown, in some embodiments, the rod body 121 is provided with a mounting hole 122 that matches the limiting member 140, and the limiting member 140 is inserted into the rod body 121 through the mounting hole 122. Thus, the limiting member 140 is inserted into the drive rod 120 through the mounting hole 122, protruding from the drive rod 120, thereby enabling it to cooperate with the limiting groove 132. This implementation is simple and easy to carry out.

[0048] In one example, the limiting member 140 includes a pin that is inserted into the rod 121 through a mounting hole 122.

[0049] It should be noted that the corresponding limiting member 140 is a groove provided on the rod body 121 of the drive rod 120, and the eccentric cam 130 is provided with a first mounting groove 131 and a limiting block protruding from the inner wall of the first mounting groove 131. The eccentric cam 130 is sleeved on the rod body 121 through the first mounting groove 131, and the groove of the limiting member 140 cooperates with the limiting block to abut against the eccentric cam 130.

[0050] like Figure 5 As shown, in some embodiments, the second limiting portion 160 is disposed away from the rotation axis 110 relative to the first limiting portion 150. The second limiting portion 160 is detachably disposed on the rod body 121. Thus, when the drive component 100 and the massage assembly 200 are assembled, the eccentric cam 130 is mounted to the drive rod 120, and the eccentric cam 130 abuts against the first limiting portion 150. By detachably disposing the second limiting portion 160 on the rod body 121 and then mounting the second limiting portion 160 to the rod body 121, the second limiting portion 160 abuts against the eccentric cam 130, restricting the eccentric cam 130 from moving axially along the drive rod 120. This method facilitates the assembly of the drive component 100 and the massage assembly 200.

[0051] like Figure 5 as well as Figure 8As shown, in some embodiments, the eccentric cam 130 includes an eccentric drive portion 133 for transmission connection with the shoulder massager 210. Thus, the shoulder massager 210 is mounted on the eccentric cam 130 via transmission connection with the eccentric drive portion 133. A first drive mechanism 400 drives the rotating shaft 110 to rotate, and a drive rod 120, transmission-connected to the rotating shaft 110, drives the shoulder massager 210 to move synchronously, thereby massaging the human shoulder. During the massage, the drive rod 120 drives the eccentric drive portion 133 to rotate, causing the shoulder massager 210 to undergo eccentric motion. This allows the shoulder massager 210 to simulate the trajectory of a human hand kneading the shoulder, achieving a kneading massage of the human shoulder and enhancing the shoulder massage effect.

[0052] like Figure 5 as well as Figure 8 As shown, in some embodiments, the eccentric cam 130 is further provided with a protrusion 134 adjacent to the eccentric drive part 133, and the drive component 100 also includes a limiting ring 135 fixedly connected to the eccentric cam 130. The limiting ring 135 and the protrusion 134 are spaced apart to form a limiting structure that restricts the movement of the shoulder massage member 210 along the axial direction of the eccentric cam 130. Thus, when the shoulder massage member 210 is assembled with the eccentric cam 130, the shoulder massage member 210 is mounted on the eccentric drive part 133 and limited by the protrusion 134. Then the limiting ring 135 is fixed to the eccentric cam 130 to form a limiting structure that restricts the movement of the shoulder massage member 210 along the axial direction of the eccentric cam 130.

[0053] like Figure 5 as well as Figure 8 As shown, in some embodiments, the drive rod 120 is further provided with a connecting portion 123 for rotatably connecting with the neck massager 220. The connecting portion 123 and the eccentric cam 130 are spaced apart along the axial direction of the drive rod 120. Thus, by rotatably connecting with the neck massager 220 through the connecting portion 123, the neck massager 220 is mounted on the drive rod 120. When the first drive mechanism 400 drives the rotating shaft 110 to drive the drive rod 120, the drive rod 120 can drive the neck massager 220 to rotate.

[0054] It should be noted that there are various ways in which the connecting part 123 can be rotatably connected to the neck massager 220, including but not limited to the connection of the bearing 124, the connection of the bushing, etc.

[0055] like Figure 5 as well as Figure 8 As shown, in some embodiments, the connecting part 123 includes a bearing 124, and the neck massage member 220 is rotatably connected to the drive rod 120 through the bearing 124.

[0056] It should be noted that the number of bearings 124 can be 1, 2, 3, etc., and can be set according to actual needs.

[0057] like Figure 5 As shown in one example, there are two bearings 124, which are respectively disposed at both ends of the neck massage member 220.

[0058] like Figure 5 As shown, in some embodiments, a portion of the neck massage element 220 abuts against the eccentric cam 130 to restrict the movement of the eccentric cam 130 along the axial direction of the drive rod 120. Thus, by using a portion of the neck massage element 220 as a limiting part to restrict the movement of the eccentric cam 130 along the axial direction of the drive rod 120, the number of components in the drive component 10 and the massage device 10 can be reduced, making the structure of the massage device 10 more compact and facilitating miniaturization.

[0059] like Figures 1 to 3 As shown, in some embodiments, the massage device 10 includes two massage components 200 and two drive components 100, and a first drive mechanism 400 can drive the two drive rods 120 to rotate synchronously. Thus, a single first drive mechanism 400 can drive the two drive rods 120 to rotate synchronously, thereby driving the two massage components 200. This reduces the need for a power source 410 and lowers the manufacturing cost of the massage device 10.

[0060] It should be noted that the first drive mechanism 400 includes devices that directly provide rotational power, such as servo motors and rotary hydraulic cylinders, as well as other devices that indirectly provide rotational power, such as pneumatic rods / hydraulic cylinders / linear motors + gear rack mechanisms, pneumatic rods / hydraulic cylinders / linear motors + crank rocker mechanisms or crank slider mechanisms, servo motors + gearboxes, servo motors + flexible transmission mechanisms, etc., which can drive the rotating shaft 110 to rotate.

[0061] like Figure 3 As shown, in some embodiments, the first drive mechanism 400 includes a power source 410 and a transmission unit 420. The power source 410 is disposed on the support assembly 300, and the power source 410 is connected to two rotating shafts 110 respectively through the transmission unit 420. In this way, the rotation of the rotating shafts 110 is realized by the cooperation of the power source 410 and the transmission unit 420, so that the position between the power source 410 and the rotating shafts 110 can be flexibly set, reducing the design difficulty of the massage device 10.

[0062] It should be noted that the transmission unit 420 can be implemented in various ways, including but not limited to belt drive assembly, chain drive assembly, gear drive assembly, etc.

[0063] It should be noted that the power source 410 can be implemented in various ways, including by means of an electric motor, etc.

[0064] like Figure 3 as well as Figure 8 As shown, in some embodiments, the transmission unit 420 includes a transmission gear 421 rotatably mounted on the support assembly 300, a worm gear 422 coaxially rotatably connected to the transmission gear 421, and two gear sets 423 meshing with the transmission gear 421. The power source 410 includes a worm 411 that drives the worm gear 422. The two gear sets 423 correspond one-to-one with the two drive components 100 to drive the two rotating shafts 110 to rotate synchronously. Thus, when the massage device 10 is in use, the power source 410 outputs power, which drives the worm gear 422 to rotate via the worm 411. This, in turn, drives the two gear sets 423 to rotate via the transmission gear 421, causing the two rotating shafts 110 to rotate synchronously, and consequently, causing the two massage components 200 to rotate synchronously so that the massage device 10 can perform a massage.

[0065] It should be noted that the "protrusion 134" can be "a part of the eccentric cam 130", that is, the "protrusion 134" is integrally formed with "other parts of the eccentric cam 130, such as the eccentric drive part 133"; or it can be a separate component that can be separated from "other parts of the eccentric cam 130, such as the eccentric drive part 133", that is, the "protrusion 134" can be manufactured independently and then combined with "other parts of the eccentric cam 130, such as the eccentric drive part 133" to form a whole. The expressions "a certain body" and "a certain part" in this disclosure are only one embodiment, for ease of reading, and not for limiting the scope of protection of this disclosure. As long as it includes the above features and has the same function, it should be understood as an equivalent technical solution of this disclosure.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
