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] With increasingly sedentary work and lifestyles, people are prone to muscle discomfort, leading to a growing market demand for massage devices that can provide muscle massage. Some massage devices integrate multiple massage components, allowing adjustment of the spacing and / or angle between these components to suit the massage needs of different user body parts. However, the complex transmission structure of these devices makes it difficult to independently adjust the massage range of each component to meet varying user preferences for massage intensity, thus hindering a better user experience. 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 adjust their relative positions, thereby improving the user experience of 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 mounting housing, an adjusting assembly, a connecting member, a transmission rod, and a telescopic assembly. The mounting housing includes a housing body. The adjusting assembly includes an adjusting housing and a driving housing. The adjusting housing and the driving housing are rotatably connected. The connecting member is movably connected to the adjusting housing and is in a transmission engagement with the driving housing. The connecting member has a connecting portion for connecting with a massage member. The transmission rod is rotatably disposed on the mounting housing. The transmission rod is slidably connected to the driving housing and is capable of driving the driving housing to rotate. The telescopic assembly includes a telescopic portion that is transmissionally connected to at least one of the driving housing and the adjusting housing. The telescopic portion is used to drive the adjusting assembly to slide relative to the mounting housing.

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

[0008] In one embodiment, the drive housing has a non-circular transmission hole and a transmission notch at one end of the transmission hole. One end of the transmission rod is inserted into the transmission hole through the transmission notch and slides with the transmission hole.

[0009] In one embodiment, the transmission rod is non-cylindrical and is sleeved with the transmission hole;

[0010] And / or, the end of the transmission rod is provided with an anti-rotation protrusion, and the side wall of the transmission hole is provided with an anti-rotation groove that slides with the anti-rotation protrusion.

[0011] In one embodiment, one of the drive housing and the transmission rod is provided with a slide rail, and the other is provided with a slider that slides in cooperation with the slide rail, and the slider is anti-rotating in cooperation with the slide rail.

[0012] In one embodiment, the adjusting housing has a limiting cavity and a limiting notch communicating with the limiting cavity. The connecting member includes a rotating part rotatably disposed in the limiting cavity, the connecting part being fixedly connected to the rotating part and exposed in the limiting notch. At least a portion of the driving housing is disposed within the limiting cavity and is in transmission engagement with the rotating part.

[0013] In one embodiment, the connecting part includes a connecting protrusion fixedly connected to the rotating part, at least a portion of the connecting protrusion being disposed outside the limiting cavity through a limiting notch; the length direction of the connecting protrusion is not coaxial with the rotation axis of the transmission rod.

[0014] In one embodiment, the mounting housing includes a guide rail fixed to the housing body, and the adjusting housing includes a guide portion that guides and engages with the guide rail.

[0015] In one embodiment, the guide rail is provided with a guide groove, and at least a portion of the guide portion protrudes from the adjustment shell and is inserted into the guide groove.

[0016] In one embodiment, the telescopic component includes a lead screw rotatably disposed on the shell body, a lead screw nut that engages with the lead screw in a helical transmission, and a first linkage member. One end of the first linkage member is fixedly connected to the lead screw nut, and the other end is provided with a telescopic part and is fixedly connected to one of the adjusting shell and the driving shell.

[0017] In one embodiment, the telescopic assembly further includes a driver for driving the lead screw to rotate.

[0018] In one embodiment, the telescopic assembly includes a transmission unit, a screw rotatably mounted on the housing body, and a second linkage member. The transmission unit includes a one-way bearing coaxially connected to the transmission rod, a driving wheel coaxially connected to the one-way bearing, and a driven wheel cooperating with the driving wheel. The driven wheel is coaxially connected to the screw. The screw has a first helical groove and a second helical groove with the opposite rotation direction. One end of the first helical groove communicates with one end of the second helical groove, and the other end of the first helical groove communicates with the other end of the second helical groove. One end of the second linkage member slides within the first and second helical grooves, and the other end of the second linkage member has a telescopic portion and is fixedly connected to one of the adjusting housing and the driving housing. When the transmission rod drives the screw to rotate via the transmission unit, the second linkage member can slide along the first helical groove, causing the adjusting assembly to move upwards. The second linkage member can also slide along the second helical groove, causing the adjusting assembly to move downwards.

[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 mounting housing is fixed to the support device. The power mechanism is disposed on the support device and is drively connected to a transmission rod. The massage element is connected to the connecting portion.

[0021] During assembly, the connecting parts and transmission rods of this massage device are integrated into the adjustment assembly, allowing the connecting parts to rotate relative to the adjustment shell and be connected to the transmission rod via the drive shell. At this point, the mounting shell is fixed to the support assembly, connected to the massage element via the connecting part, and connected to the power mechanism via the transmission rod to drive the massage element's movement. This completes the assembly of the massage device, improving assembly efficiency. When it is necessary to adjust the relative position of the massage element with respect to the mounting shell to adjust the massage intensity, the telescopic part of the telescopic assembly moves the adjustment assembly, causing the massage element to move with the adjustment assembly, thus adjusting the distance between the massage element and the mounting shell. In this way, the connecting device can both control the movement of the massage element and adjust its relative position, improving the user experience of the massage device.

[0033] 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.

[0034] 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.

[0035] To better understand the connection device 40 of this disclosure, it will be described using a massage device 1 in which the connection device 40 is applied.

[0036] like Figure 1 as well as Figure 2 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.

[0037] Among them, such as Figures 2 to 4 As shown, the connecting device 40 includes a mounting shell 100 fixed to the supporting device 10, an adjusting assembly 200, a connecting member 300, a transmission rod 400, and a telescopic assembly 500. The mounting shell 100 includes a shell body 110. The adjusting assembly 200 includes an adjusting shell 210 and a driving shell 220. The adjusting shell 210 is rotatably connected to the driving shell 220 and slidably connected to the shell body 110. The connecting member 300 is movably connected to the adjusting shell 210 and is in a transmission engagement with the driving shell 220. The connecting member 300 has a connecting portion 310 that connects to the massage member 30. The transmission rod 400 is rotatably mounted on the mounting shell 100 and is transmissionally connected to the power mechanism 20. The transmission rod 400 is slidably connected to the driving shell 220 and can drive the driving shell 220 to rotate. The telescopic assembly 500 includes a telescopic portion 501 that is transmissionally connected to at least one of the driving shell 220 and the adjusting shell 210. The telescopic portion 501 is used to drive the adjusting assembly 200 to slide relative to the mounting shell 100. The power mechanism 20 is installed on the bearing device 10 and is connected to the transmission rod 400 for transmission.

[0038] During assembly, the connector 300 and transmission rod 400 are integrated into the adjustment assembly 200, allowing the connector 300 to rotate relative to the adjustment housing 210 and be connected to the transmission rod 400 via the drive housing 220. At this time, the mounting housing 100 is fixed to the support assembly, connected to the massage element 30 via the connecting part 310, and connected to the power mechanism 20 via the transmission rod 400 to drive the massage element 30 to move. This completes the assembly of the massage device 1. Thus, 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 housing 220 to rotate via the transmission rod 400, and the drive housing 220 drives the massage element 30 mounted on the connector 300 to move. When it is necessary to adjust the relative position of the massage element 30 with respect to the mounting shell 100 to adjust the massage intensity of the massage element 30, the telescopic part 501 of the telescopic component 500 drives the adjustment component 200 to move, so that the massage element 30 also moves with the adjustment component 200, thereby adjusting the distance between the massage element 30 and the shell body 110. In this way, the connecting device 40 can both control the movement of the massage element 30 and adjust the relative position of the massage element 30, which helps to improve the user experience of the massage device 1.

[0039] Understandably, the massage component 30 is independently assembled on the connecting device 40 via the connecting part 310, 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, resulting in a compact structure and facilitating the miniaturization of the massage device 1.

[0040] Furthermore, it is understandable that, since the adjusting shell 210 is slidably connected to the shell body 110, during the process of the transmission rod 400 driving the drive shell 220 to rotate and driving the connecting member 300 to rotate, the adjusting shell 210 will not move accordingly, allowing the connecting member 300 to move relative to the adjusting shell 210. Thus, the movement trajectory of the connecting part 310 can be controlled through the adjusting shell 210. The adjusting shell 210 can move up and down relative to the shell body 110, and can also drive the connecting member 300 to move up and down relative to the shell body 110.

[0041] It should be noted that there are various ways to achieve the sliding connection between the adjusting shell 210 and the shell body 110, including but not limited to slide rails and slide grooves, guide rails and guide blocks, etc.

[0042] like Figure 3As shown, in some embodiments, the mounting housing 100 includes a guide rail 120 fixed to the housing body 110. The adjusting housing 210 includes a guide portion 211 that guides and cooperates with the guide rail 120. Thus, by guiding and cooperating with the guide rail 120, the adjusting housing 210 and the housing body 110 can be easily slidably connected. Consequently, during the process of the transmission rod 400 driving the drive housing 220 to rotate and driving the connecting member 300 to rotate, the adjusting housing 210 will not move accordingly, allowing the connecting member 300 to move relative to the adjusting housing 210, thereby enabling the movement trajectory of the connecting member 310 to be controlled by the adjusting housing 210. The adjusting housing 210 can move up and down relative to the housing body 110, and can also drive the connecting member 300 to move up and down relative to the housing body 110.

[0043] like Figure 3 As shown, in some embodiments, the guide rail 120 is provided with a guide groove 121, and at least a portion of the guide portion 211 protrudes from the adjusting shell 210 and is inserted into the guide groove 121. In this way, by setting the guide portion 211 on the adjusting shell 210, it is easy to insert into the guide groove 121, thereby achieving a guiding fit between the adjusting shell 210 and the mounting shell 100.

[0044] like Figure 4 As shown, in some embodiments, the drive housing 220 is provided with a non-circular transmission hole 221 and a transmission notch 222 at one end of the transmission hole 221. One end of the transmission rod 400 is inserted into the transmission hole 221 through the transmission notch 222 and slides in cooperation with the transmission hole 221. In this way, the internal space of the drive housing 220 can be used to accommodate the transmission rod 400, so that the two fit tightly.

[0045] Optionally, in some embodiments, the transmission rod 400 is non-cylindrical and fits into the transmission hole 221. This facilitates assembly and allows for a sliding connection between the transmission rod 400 and the drive housing 220, but the two cannot rotate relative to each other.

[0046] Non-cylinders include polygonal regular prisms, elliptical cylinders, semi-cylinders, etc.

[0047] Optionally, in one embodiment, the end of the transmission rod 400 is provided with an anti-rotation protrusion 410, and the side wall of the transmission hole 221 is provided with an anti-rotation groove 223 that slides with the anti-rotation protrusion 410. Thus, by providing the cooperation between the anti-rotation protrusion 410 and the anti-rotation groove 223, a sliding connection between the transmission rod 400 and the drive housing 220 is achieved, but the two cannot rotate relative to each other, which helps to reduce the manufacturing cost of the transmission rod 400.

[0048] Optionally, in some embodiments, one of the drive housing 220 and the transmission rod 400 is provided with a slide rail (not shown), and the other is provided with a slider (not shown) that slides in cooperation with the slide rail, and the slider is anti-rotating in cooperation with the slide rail.

[0049] like Figure 4As shown, in some embodiments, the adjusting shell 210 is provided with a limiting cavity 212 and a limiting notch 213 communicating with the limiting cavity 212. The connecting member 300 includes a rotating part 320 rotatably disposed in the limiting cavity 212. The connecting part 310 is rotatably connected to the rotating part 320 and exposed in the limiting notch 213. At least a portion of the driving shell 220 is disposed within the limiting cavity 212. Thus, the limiting cavity 212 restricts the rotation range of the rotating part 320 while protecting the driving shell 220 and the rotating part 320.

[0050] Understandably, the drive housing 220 needs to be rotatably connected to the adjusting housing 210, and the rotating part 320 also needs to rotate. The setting of the limiting cavity 212 also facilitates the storage of lubricant in the limiting cavity 212, reduces the amount of rotational wear between the drive housing 220 and the rotating part 320 and the adjusting housing 210, and improves the service life.

[0051] Furthermore, in some embodiments, the rotating part 320 is limited by the convex surface of the ball and the concave surface of the adjusting shell 210, so that the rotating part 320 can rotate in all directions, making it easy to plan the rotation trajectory of the rotating part 320, so that the connecting part 310 can drive the massage member 30 to perform massage movement along the set trajectory.

[0052] Optionally, the connecting part 310 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 a spherical convex surface).

[0053] It should be noted that "the connecting part 310 is exposed in the limiting notch 213" should be interpreted broadly. This includes at least a portion of the connecting part 310 protruding from the limiting notch 213, and also includes the fact that the connecting part 310 is visible through the limiting notch 213, i.e., exposed in the projection area of ​​the limiting notch 213. The connecting part 310 only needs to be able to connect to the massage component 30 through the limiting notch 213.

[0054] like Figure 4 As shown, in some embodiments, the connecting portion 310 includes a connecting protrusion 311 fixedly connected to the rotating portion 320. At least a portion of the connecting protrusion 311 is disposed outside the limiting cavity 212 through a limiting notch 213. The length direction of the connecting protrusion 311 is not coaxial with the rotation axis of the transmission rod 400. In this way, the connecting protrusion 311 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 311.

[0055] It should be noted that the connection methods between the connecting protrusion 311 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.

[0056] like Figure 4 As shown, the drive housing 220 can be implemented in various ways, as long as it forms the structure described above. For example, it can be formed by fixing and splicing multiple housings together. It can also be formed by integral molding. Optionally, the drive housing is formed by fixing it to the housing with a drive member that can drive the connecting member to rotate.

[0057] The specific methods for connecting the connecting part to the massage component 30 include, but are not limited to, non-removable fixed connections, such as welding, riveting, and bonding. They also include detachable fixed connections, such as screwing, snap-fitting, and locking.

[0058] It should be noted that the telescopic component 500 can be implemented in various ways, including but not limited to power devices that directly drive the telescopic movement of the telescopic part 501, such as electromagnetic telescopic rods, pneumatic rods, hydraulic rods, and linear motors. It also includes power components that indirectly realize the telescopic movement of the telescopic part 501, such as gear and rack assembly + servo motor, lead screw 510 nut assembly + servo motor, and flexible transmission assembly + servo motor.

[0059] See you later Figure 3 As shown, in some embodiments, at least one of the adjusting shell 210 and the driving shell 220 is slidably connected to the shell body 110. The telescopic assembly 500 includes a lead screw 510 rotatably disposed on the shell body 110, a lead screw nut 520 that is helically driven with the lead screw 510, and a first linkage member 530. One end of the first linkage member 530 is fixedly connected to the lead screw nut 520, and the other end is provided with a telescopic part 501, which is fixedly connected to one of the adjusting shell 210 and the driving shell 220. In this way, by using the cooperation of the lead screw 510 and the lead screw nut 520 to drive the first linkage member 530 to extend and retract along the length direction of the transmission rod 400, the relative position of the massage member 30 can be adjusted, which is easy to implement. Moreover, it can achieve instant rotation and stop, which is easy to control.

[0060] It should be noted that the lead screw 510 can be driven manually or electrically.

[0061] See you later Figure 2 As shown, in some embodiments, the telescopic assembly 500 further includes a driver 41 for driving the lead screw 510 to rotate. Thus, using the driver 41 to electrically control the rotation of the lead screw 510 improves the user experience of the massage device 1.

[0062] It should be noted that the driver 41 can be implemented in various ways, including but not limited to motors.

[0063] like Figure 5 as well as Figure 6As shown, in some embodiments, at least one of the adjusting shell 210 and the driving shell 220 is slidably connected to the shell body 110. The telescopic assembly 500 includes a transmission unit 540, a screw 550 rotatably disposed on the shell body 110, and a second linkage member 560. The transmission unit 540 includes a one-way bearing 541 coaxially connected to the transmission rod 400, a driving wheel 542 coaxially connected to the one-way bearing 541, and a driven wheel 543 drivingly engaged with the driving wheel 542. The driven wheel 543 is coaxially connected to the screw 550. The screw 550 is provided with a first helical groove 551 and a second helical groove 552 with the opposite rotation direction to the first helical groove 551. One end of the first helical groove 551 communicates with one end of the second helical groove 552, and the other end of the first helical groove 551 communicates with the other end of the second helical groove 552. One end of the second linkage member 560 slides within the first spiral groove 551 and the second spiral groove 552, and the other end of the second linkage member 560 is provided with a telescopic part 501, which is fixedly connected to one of the adjusting shell 210 and the driving shell 220. When the transmission rod 400 drives the screw 550 to rotate through the transmission unit 540, the second linkage member 560 can slide along the first spiral groove 551 and drive the adjusting component 200 to move upward. The second linkage member 560 can also slide along the second spiral groove 552 and drive the adjusting component 200 to move downward. Thus, the transmission rod 400 cooperates with the one-way bearing 541, so that when the power mechanism 20 drives the transmission rod 400 to rotate in the first rotation direction, the transmission rod 400 and the driving shell 220 are in transmission cooperation, and the driving shell 220 can drive the connecting member 300 to rotate, thereby driving the massage head to perform massage movements. When it is necessary to adjust the relative position of the massage element 30 with respect to the mounting shell 100 to adjust the massage intensity of the massage element 30, the power mechanism 20 drives the transmission rod 400 to rotate in the opposite direction of the first rotation direction. At this time, the one-way bearing 541 drives the drive wheel 542 to rotate, which in turn drives the driven wheel 543 and the screw 550 to rotate coaxially. When the screw 550 rotates, it can drive the second linkage 560 to slide along the first spiral groove 551 and drive the adjustment component 200 to move upward, thereby increasing the distance between the massage element 30 and the shell body 110. If the second linkage 560 is engaged with one end of the first spiral groove 551, continuing to rotate the transmission rod 400 will switch the second linkage 560 to engage with the second spiral groove 552, allowing the second linkage 560 to slide along the second spiral groove 552 and drive the adjustment component 200 to move downward, thereby reducing the distance between the massage element 30 and the shell body 110.

[0064] Similarly, when the second linkage 560 engages with the other end of the second spiral groove 552, continuing to rotate the transmission rod 400 allows the second linkage 560 to switch to engaging with the first spiral groove 551, enabling the second linkage 560 to slide along the first spiral groove 551 and drive the adjustment component 200 upward. Thus, the connecting device 40 can both control the movement of the massage component 30 and adjust its relative position, thereby improving the user experience of the massage device 1.

[0065] It should be noted that there are several ways to specifically implement "the driving wheel 542 driving the driven wheel 543 to rotate". For example, the driving wheel 542 can drive the driven wheel 543 to rotate through a flexible transmission component (that is, forming a flexible transmission component such as a belt drive assembly or a chain drive assembly). Another example is... Figure 6 As shown, in some embodiments, the driving wheel 542 is a driving gear, and the driven wheel 543 is a driven gear that meshes with the driving gear. This improves the transmission accuracy and reliability between the driving wheel 542 and the driven wheel 543, which is beneficial for improving the accuracy of the massage member 30's position adjustment.

[0066] Optionally, such as Figure 6 As shown, in some embodiments, the driving gear can also be indirectly meshed with the driven gear through the transmission gear 544, so that the position between the driving gear and the driven gear can be flexibly set, reducing the difficulty of arranging the screw 550 and the transmission rod 400.

[0067] In other embodiments, the driving gear and the driven gear mesh directly, which can reduce the transmission distance and make the structure of the connecting device more compact.
