Description

Technical Field

[0001] This disclosure relates to the field of health care device technology, and in particular to a connecting device and a massage device. Background Technology

[0002] Massage devices, as health care instruments 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 usually designed according to the structural characteristics of different parts of the human body, such as neck massage devices, waist massage devices, and dual-area massage devices.

[0003] In related technologies, massage devices typically utilize a drive mechanism to move massage components, which then need to be connected to the carrier component of the massage assembly via a connecting unit to restrict or control their movement trajectory. This necessitates the massage components connecting to both the drive mechanism and the connecting unit, resulting in numerous connection structures on the massage components and the need to avoid motion interference. Consequently, a large clearance space is required within the massage device, making it relatively bulky and hindering miniaturization. Utility Model Content

[0004] This disclosure provides a connecting device and a massage device. The connecting device can both control the movement of the massage components and transmit power to the power mechanism. It has a compact structure, which is beneficial for miniaturizing the massage device.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a connecting device is provided, including a housing assembly, a connector, and a driving member. The housing assembly includes a limiting cavity, which includes a limiting notch, a transmission notch opposite to the limiting notch, and an annular limiting surface disposed inside the limiting cavity. The annular limiting surface surrounds the limiting notch and is spherically shaped. The connector includes a rotating portion rotatably disposed within the limiting cavity and a connecting portion for fixed connection with a massage member. The rotating portion includes a spherical protrusion adapted to the annular limiting surface, which limits and engages with the annular limiting surface. The rotating portion is anti-disengaged with the limiting notch and spaced apart from the transmission notch. The connecting portion is fixedly connected to the rotating portion and exposed outside the limiting notch. The driving member includes a driving portion that drives the rotating portion and a first transmission portion exposed outside the transmission notch. The driving member is rotatably disposed within the limiting cavity, and the first transmission portion is fixedly connected to the driving portion and capable of driving the driving portion to rotate.

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

[0008] In one embodiment, the rotating part is capable of rotating about the center of the spherical convex surface.

[0009] In one embodiment, the rotating part includes a transmission surface that drives the driving part, and the driving part includes an end face that abuts against the transmission surface. The end face is inclined along the depth direction of the limiting cavity. When the driving member rotates, the end face pushes against the transmission surface, causing the connecting part to rotate around a closed curve.

[0010] In one embodiment, the housing assembly further includes a guide groove communicating with the limiting cavity, and the connecting member includes a limiting protrusion fixedly connected to the rotating part. The limiting protrusion is movably disposed within the guide groove. When the driving member rotates, its end face abuts against the transmission surface, causing the limiting protrusion to swing up and down within the guide groove.

[0011] In one embodiment, there are two limiting protrusions, which are fixedly mounted on the rotating part, and the limiting protrusions correspond one-to-one with the guide grooves.

[0012] And / or, the middle part of the transmission surface and the middle part of the end surface are provided with a positioning hole on one side and a positioning pin that rotates with the positioning hole on the other side.

[0013] In one embodiment, the center of the spherical convex surface is located in the rotating portion. The connector includes a second transmission portion fixed to the rotating portion and disposed opposite to the connecting portion. The second transmission portion is drively connected to the driving portion, and one of the second transmission portion and the connecting portion is eccentrically disposed with respect to the rotation axis of the driving portion.

[0014] In one embodiment, the connecting portion includes a connecting protrusion fixedly connected to the rotating portion, at least a portion of which is disposed outside the limiting cavity via a limiting notch. The longitudinal direction of the connecting protrusion is not coaxial with the rotation axis of the driving member.

[0015] In one embodiment, the housing assembly includes a limiting shell with a limiting groove and a cover plate with a transmission notch. The limiting shell and the cover plate are fixedly connected so that the limiting groove forms a limiting cavity, and the limiting shell has a limiting notch. The cover plate carries a driving component, and the driving component is anti-disengaged in a transmission notch engagement.

[0016] In one embodiment, the first transmission part includes a transmission groove disposed opposite to the limiting notch.

[0017] Alternatively, the first transmission part includes a protruding transmission protrusion, at least a portion of which is disposed outside the limiting cavity through a transmission notch.

[0018] In one embodiment, the connecting device further includes a transmission rod fixedly connected to the first transmission part. One end of the transmission rod can pass through a transmission notch for rotatable connection with the bearing device, so as to push the driving member through the other end of the transmission rod.

[0019] According to a second aspect of the present disclosure, a massage device is also provided, including a support device, a power mechanism, a massage element, and a connecting device as described in any of the above embodiments. A housing assembly is fixed to the support device. The power mechanism is disposed on the support device and is drively connected to a first transmission part. The massage element is connected to the connecting part.

[0020] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0021] During assembly, the connector and drive component are integrated into the housing assembly, allowing the connector to rotate relative to the housing assembly and be driven by the drive component. The housing assembly is then fixed to the support assembly, connected to the massage element via the connector, and driven by the power mechanism via the first transmission part. This completes the assembly of the massage device, improving assembly efficiency. When the massage device is needed, the power mechanism generates power, which drives the drive component to rotate via the first transmission part, and the drive component then drives the massage element mounted on the connector. The spherical convex surface and the annular limiting surface provide a limiting fit, allowing the connector to drive the massage element along a set trajectory. This connecting device not only controls the movement of the massage element but also transmits power to the power mechanism; its compact structure facilitates the miniaturization of the massage device.

[0035] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0036] 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 disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0037] To better understand the connection device of this disclosure, it will be described using a massage device in which the connection device is applied.

[0038] like Figure 1 As shown, in some embodiments, a massage device 1 is provided, including a support device 10, a power mechanism 20, a massage component 30, and a connecting device 40.

[0039] Among them, such as Figures 2 to 4 As shown, the connecting device 40 includes a housing assembly 100, a connector 200, and a driving member 300 fixed to the supporting device 10. The housing assembly 100 includes a limiting cavity 101, which includes a limiting notch 1011, a transmission notch 1012 opposite to the limiting notch 1011, and an annular limiting surface 1013 disposed inside the limiting cavity 101. The annular limiting surface 1013 surrounds the limiting notch 1011 and is spherically shaped. The connector 200 includes a rotating part 210 rotatably disposed within the limiting cavity 101 and a connecting part 220 fixedly connected to the massage member 30. The rotating part 210 includes a spherical protrusion 211 adapted to the annular limiting surface 1013, which limits and engages with the annular limiting surface 1013. The rotating part 210 is anti-detached from the limiting notch 1011 and is spaced apart from the transmission notch 1012. The connecting part 220 is fixedly connected to the rotating part 210 and exposed in the limiting notch 1011. The driving member 300 includes a driving part 310 that is in transmission cooperation with the rotating part 210 and a first transmission part 320 exposed in the transmission notch 1012. The driving member 300 is rotatably disposed in the limiting cavity 101. The first transmission part 320 is fixedly connected to the driving part 310 and can drive the driving part 310 to rotate. The power mechanism 20 is disposed on the bearing device 10 and is in transmission connection with the first transmission part 320.

[0040] During assembly, the connector 200 and the drive component 300 are integrated into the housing assembly 100, allowing the connector 200 to rotate relative to the housing assembly 100 and be connected to the drive component 300 via a transmission mechanism. The housing assembly 100 is then fixed to the support assembly, connected to the massage component 30 via the connector 220, and connected to the power mechanism 20 via the first transmission part 320, thus completing the assembly of the massage device 1. In this way, the connector 40 can be modularly assembled onto the support assembly 10, improving the assembly efficiency of the massage device 1. When the massage device 1 is needed for massage, the power mechanism 20 generates power, which drives the drive component 300 to rotate via the first transmission part 320, and the drive component 300 drives the massage component 30 mounted on the connector 200 to move. Due to the limiting fit between the spherical convex surface 211 and the annular limiting surface 1013, the connector 200 drives the massage component 30 to perform massage movements along a set trajectory. The connecting device 40 can both control the movement of the massage component 30 and transmit the power of the power mechanism 20. Its compact structure is conducive to the miniaturization of the massage device 1.

[0041] Understandably, the massage component 30 is independently assembled on the connecting device 40 via the connecting part 220, and will not interfere with the power mechanism 20 or other moving components on the bearing device 10. This also makes the massage device 1 less need to have a large amount of clearance space, and the structure is compact, which is conducive to further miniaturization of the massage device 1.

[0042] In addition, the rotating part 210 is limited and engaged with the annular limiting surface 1013 of the housing assembly 100 through the spherical convex surface 211, so that the rotating part 210 can rotate in all directions, making it easy to plan the rotation trajectory of the rotating part 210, so that the connecting part 220 can drive the massage member 30 to perform massage movements along the set trajectory.

[0043] Optionally, the connecting part 220 can drive the massage member 30 to reciprocate, reciprocate along a two-dimensional closed curve (e.g., along a circular curve or an elliptical curve), or reciprocate along a three-dimensional closed curve (e.g., an elliptical trajectory curved around the spherical convex surface 211).

[0044] It should be noted that "the annular limiting surface 1013 is in the shape of an inner sphere" should be interpreted broadly, as it is part of the inner sphere and can be formed by setting notches at both ends of the inner sphere.

[0045] It should be noted that "the connecting part 220 is exposed in the limiting notch 1011" should be interpreted broadly. This includes at least a portion of the connecting part 220 protruding from the limiting notch 1011, and also includes the fact that the connecting part 220 is visible through the limiting notch 1011, i.e., exposed in the projection area of ​​the limiting notch 1011. The connecting part 220 can be connected to the massage component 30 through the limiting notch 1011.

[0046] It should be noted that "the first transmission part 320 is exposed outside the transmission notch 1012" should be interpreted broadly, including at least a portion of the first transmission part 320 protruding from the transmission notch 1012 (see reference). Figure 5 (Understanding), this also includes the connection portion 220 being visible through the transmission notch 1012, that is, the area exposed in the projection area of ​​the transmission notch 1012 (see reference). Figure 4 (Understanding). The first transmission unit 320 can be connected to the drive mechanism through the transmission notch 1012.

[0047] like Figure 4 as well as Figure 5As shown, in some embodiments, the rotating part 210 includes a transmission surface 212 that drives the driving part 310, and the driving part 310 includes an end face 311 that abuts against the transmission surface 212. The end face 311 is inclined along the depth direction of the limiting cavity 101. When the driving member 300 rotates, the end face 311 pushes against the transmission surface 212, causing the connecting part 220 to rotate around a closed curve. Thus, when the power mechanism 20 drives the driving member 300 to rotate, the inclined end face 311 can push against the rotating part 210 along the rotation direction of the driving member 300, causing the rotating part 210 to also deflect along the rotation direction of the driving member 300, causing the connecting part 220 to rotate around a closed curve, thereby driving the massage member 30 on the connecting part 220 to rotate along another closed curve, achieving kneading massage.

[0048] Optionally, in one example, the drive member 300 is frustum-shaped and has an end face 311 that is inclined within the limiting cavity 101.

[0049] like Figure 3 as well as Figure 4 As shown, in some embodiments, the housing assembly 100 further includes a guide groove 102 communicating with the limiting cavity 101, and the connector 200 includes a limiting protrusion 230 fixedly connected to the rotating part 210. The limiting protrusion 230 is movably disposed within the guide groove 102. When the drive member 300 rotates, the end face 311 pushes against the transmission surface 212, causing the limiting protrusion 230 to swing up and down within the guide groove 102. Thus, when the power mechanism 20 drives the drive member 300 to rotate, the inclined end face 311 can push against the rotating part 210 along the rotation direction of the drive member 300, causing the rotating part 210 to also deflect along the rotation direction of the drive member 300, causing the connector 220 to rotate. During the rotation of the connecting part 220, the limiting protrusion 230 and the guide groove 102 guide the connecting part 220 to swing up and down along the guide groove 102 with the limiting protrusion 230. As a result, the connecting part 220 can move around a three-dimensional closed curve (for example, an elliptical trajectory curved around the spherical convex surface 211), which in turn can drive the massage element 30 on the connecting part 220 to rotate along another three-dimensional closed curve, realizing kneading massage with variable pressure, which can greatly improve the massage effect of the massage device 1.

[0050] In some embodiments, the massage element 30 is capable of kneading and massaging the neck of the human body.

[0051] like Figure 4 as well as Figure 5 As shown, in some embodiments, the limiting protrusion 230 includes two protrusions, which are fixedly mounted on the rotating part 210, and the limiting protrusion 230 corresponds one-to-one with the guide groove 102. In this way, the force on the rotating part 210 on the limiting cavity 101 is more uniform, and the connecting part 220 moves reliably along the closed curve.

[0052] like Figure 4 as well as Figure 5 As shown, in some embodiments, the middle portion of the transmission surface 212 and the middle portion of the end surface 311 are provided with a positioning hole 213 on one side and a positioning pin 312 that rotatably engages with the positioning hole 213 on the other side. Thus, through the positioning engagement of the positioning hole 213 and the positioning pin 312, the drive member 300 and the rotating part 210 can rotate concentrically, reducing motion eccentricity, thereby reducing wear between the rotating part 210 and the housing assembly 100, improving the reliability of the connecting device 40, and extending the service life of the massage device 1.

[0053] like Figures 2 to 4 As shown, or Figure 5 As shown, in some embodiments, the connecting portion 220 includes a connecting protrusion 221 fixedly connected to the rotating portion 210, and at least a portion of the connecting protrusion 221 is disposed outside the limiting cavity 101 through a limiting notch 1011. The length direction of the connecting protrusion 221 is not coaxial with the rotation axis of the driving member 300. In this way, the connecting protrusion 221 can be easily connected to the massage member 30, and the massage member 30 can be driven to rotate around the center of the ball through the connecting protrusion 221.

[0054] like Figure 5 As shown, the length direction of the connecting protrusion 221 is L1, and the rotation axis of the driving member 300 is L2. L1 and L2 are not coaxial.

[0055] like Figure 5 As shown, the depth direction of the limiting cavity is as shown in the Z-axis direction.

[0056] It should be noted that the connection methods between the connecting protrusion 221 and the massage component 30 include, but are not limited to, at least one of the following: plug-in fixing, detachable fixing, screw fixing, adhesive fixing, etc.

[0057] like Figure 4 as well as Figure 5As shown, in some embodiments, the housing assembly 100 includes a limiting shell 110 with a limiting groove 111 and a cover plate 120 with a transmission notch 1012. The limiting shell 110 and the cover plate 120 are fixedly connected so that the limiting groove 111 forms a limiting cavity 101, and the limiting shell 110 has a limiting notch 1011. The cover plate 120 carries the driving member 300, and the driving member 300 is anti-detached from the transmission notch 1012. Thus, by the cooperation of the limiting shell 110 and the cover plate 120, the rotating part 210 and the driving member 300 are easily rotatably encapsulated in the limiting cavity 101. Specifically, when assembling the connecting device 40, the rotating part 210 is inserted into the limiting cavity 101, and the rotating part 210 is anti-detached from the limiting notch 1011, while the connecting part 220 is exposed outside the limiting notch 1011, which facilitates assembly with the massage member 30 and restricts the movement trajectory of the massage member 30. Then, the driving component 300 is placed in the limiting cavity 101 and engages with the rotating part 210 in a transmission cooperation. Finally, the cover plate 120 is fixedly connected to the limiting shell 110, so that the cover plate 120 can support the limiting driving component 300, and the driving component 300 is anti-detached from the transmission notch 1012, while the transmission part is exposed outside the transmission notch 1012, which facilitates the transmission connection of the driving mechanism.

[0058] Optionally, such as Figure 4 As shown, in some embodiments, the first transmission part 320 includes a transmission groove 321 disposed opposite to the limiting notch 1011. Thus, the drive mechanism can be configured such that a rotating shaft is inserted into the transmission groove 321 and engages with it in a transmission relationship to drive the drive member 300 to rotate.

[0059] Optionally, such as Figure 5 As shown, in some embodiments, the first transmission part 320 includes a protruding transmission protrusion 322, at least a portion of which is disposed outside the limiting cavity 101 through a transmission notch 1012. Thus, the transmission protrusion 322 facilitates rotational connection with the drive mechanism, allowing the drive mechanism to rotate the drive member 300 via the transmission protrusion 322.

[0060] like Figure 6 As shown, in some embodiments, the rotating part 210 is capable of rotating about the center of the spherical convex surface 211. This reduces the clearance required for the movement of the rotating part 210, allowing the housing assembly 100 to be designed to be smaller, and making the structure of the connecting device 40 more compact.

[0061] Reference Figure 6In other embodiments, the center of the spherical convex surface 211 is located in the rotating portion 210. The connector 200 includes a second transmission portion 240 fixed to the rotating portion 210 opposite to the connecting portion 220. The second transmission portion 240 is drive-connected to the driving portion 310, and one of the second transmission portion 240 and the connecting portion 220 is eccentrically positioned relative to the rotation axis of the driving portion 310. Thus, during the rotation of the second connecting portion 220 driven by the driving portion 310, the eccentricity of one of the second transmission portion 240 and the connecting portion 220 relative to the rotation axis of the driving portion 310 allows the connecting portion 220 to move around a closed curve, causing the massage element 30 on the connecting portion 220 to also rotate along another closed curve, achieving a kneading massage.

[0062] It should be noted that there are various ways to implement the transmission connection between the second rotating part 210 and the driving part 310. For example, one of the second rotating part 210 and the driving part 310 is provided with a mating hole, and the other is provided with a protrusion that is in transmission engagement with the mating hole.

[0063] Combination Figure 1 , Figure 7 as well as Figure 8 In other embodiments, the connecting device 40 further includes a transmission rod 400 fixedly connected to the first transmission part 320. One end of the transmission rod 400 can pass through the transmission notch 1012 for rotatable connection with the support device 10, so as to push the driving member 300 through the other end of the transmission rod 400. Thus, when the connecting device 40 is assembled with the support device 10, the transmission rod 400 is first rotatably connected to the support device 10 to form a support structure and is connected to the drive mechanism. Then, it is fixedly connected to the support device 10 through the housing assembly 100, which facilitates pushing the driving member 300 through the other end of the transmission rod 400, and also restricts the driving member 300 and the rotating part 210 within the limiting cavity 101, so as to facilitate the driving mechanism to drive the driving member 300 to rotate through the transmission rod 400.

[0064] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
