[0002] When a swing drive is used in a massage device, an additional secondary swing section is usually provided for auxiliary massage. However, in this case, the secondary swing section has a single function, and the massage effect is not good when used for auxiliary massage, which cannot meet the user's massage needs. Utility Model Content

[0003] This invention was made in view of the above-mentioned problems, and its purpose is to provide a swing driving device, which has two auxiliary swing parts for auxiliary massage to achieve a better massage effect.

[0004] To solve the above-mentioned technical problems, this utility model provides a swing driving device, comprising: a main body having a first receiving cavity formed therein; a main swing portion extending protruding from one end of the main body along the length direction of the main body and capable of moving relative to the main body; a first auxiliary swing portion and a second auxiliary swing portion extending protruding along the width direction of the main body and spaced apart from each other, and located on the same side of the main swing portion; and a driving structure housed in the first receiving cavity and connected to the first auxiliary swing portion, the second auxiliary swing portion and the main swing portion. Under the driving action of the driving structure, the main swing portion can extend and retract, and the first auxiliary swing portion and the second auxiliary swing portion can swing towards each other.

[0005] Furthermore, the driving structure includes a drive motor, a telescopic sleeve, a slider, a first transmission component, and a second transmission component. The drive motor is housed within the first receiving cavity. The telescopic sleeve is mounted on the drive motor and connected to the main swing portion. The drive motor drives the telescopic sleeve to move relative to the main body, and the drive motor also drives the telescopic sleeve to extend and retract along the length direction of the main body. The slider is movably mounted on the telescopic sleeve and connected to the first transmission component and the second transmission component. The first transmission component and the second transmission component are respectively connected to the first secondary swing portion and the second secondary swing portion.

[0006] Furthermore, the telescopic sleeve has an inclined sliding hole through it. One side of the slider can slide along the sliding hole, and the other side is rotatably connected to the first transmission member and the second transmission member. When the slider slides along the inclined sliding hole, the slider drives the first transmission member and the second transmission member to move up and down reciprocally, so that the first transmission member and the second transmission member can swing towards each other.

[0007] Furthermore, the slider includes a sliding connection portion and a mounting portion extending vertically from the sliding connection portion. The sliding connection portion is movably mounted in the sliding hole, and the mounting portion is rotatably connected to the first transmission member and the second transmission member.

[0008] Furthermore, the sliding connection includes two first protrusions and a first pivot. The two first protrusions are located on both sides of the slider. The first pivot passes through one of the first protrusions, the sliding hole, and the other first protrusion in sequence. A portion of the first pivot is received in the sliding hole and slides along the sliding hole.

[0009] Furthermore, the mounting part includes two second protrusions and a second rotating shaft. The two second protrusions are offset from the two first protrusions, and the second rotating shaft passes through the two second protrusions.

[0010] Furthermore, the first transmission member includes a first transmission part and a first shaft part movably mounted on the first transmission part, and the second transmission member includes a second transmission part and a second shaft part movably mounted on the second transmission part. The first transmission part and the second transmission part are located between the two second protrusions, and the second rotating shaft passes through the first transmission part and the second transmission part, thereby allowing the first transmission part and the second transmission part to swing relative to the mounting part. The first shaft part and the second shaft part are fixed to the main body.

[0011] Furthermore, one end of the first transmission part is provided with two first rotating parts, which are spaced apart and located between the second protrusions. One end of the second transmission part is provided with a second rotating part, which is located between the two first rotating parts, and one end of the second rotating part is recessed to form a groove. The second rotating shaft passes through one second protrusion, one first rotating part, the groove of the second rotating part, another first rotating part, and another second protrusion in sequence. Thus, the second transmission member and the first transmission member swing towards each other under the drive of the second rotating shaft, and the second transmission member and the first transmission member can clamp and swing.

[0012] Furthermore, the first auxiliary swing portion and the second auxiliary swing portion include a sleeve portion and a second motor, the second motor being housed within the sleeve portion, and the sleeve portion being sleeved on the first transmission portion of the corresponding first transmission member and the second transmission portion of the corresponding second transmission member.

However, the present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that the present invention may be thoroughly and completely conveyed to those skilled in the art.

[0024] Please refer to the following: Figures 1 to 2 The swing drive device 100 of this utility model will be described below.

[0025] This utility model provides a swing drive device 100, which is applied to medical devices such as massage devices. Specifically, the swing drive device 100 includes a main body 20, a main swing part 10, a drive structure 30, a first auxiliary swing part 50, a second auxiliary swing part (not shown), and a control circuit board 90. The main swing part 10, the first auxiliary swing part 50, and the second auxiliary swing part are installed at one end of the main body 20. The drive structure 30 and the control circuit board 90 are housed inside the main body 20, and the drive structure 30 is connected to the main swing part 10, the first auxiliary swing part 50, the second auxiliary swing part, and the control circuit board 90. Thus, under the control of the control circuit board 90, the drive structure 30 can control the opposing swing motion and the extension and retraction motion of the swing part 10, the first auxiliary swing part 50, and the second auxiliary swing part.

[0026] Please refer to the following: Figure 1 , Figure 6 and Figure 7 The main body 20 has a cylindrical structure and an internal first receiving cavity 21 for housing the drive structure 50 and the control circuit board 90. It is understood that the main body 10 can function as a gripping part, and its external structure can be adjusted as needed. A support portion 23 extends protruding from one end of the main body 20 along its width direction, supporting a portion of the drive structure 30. The support portion 23 has an opening 231 communicating with the first receiving cavity 21. A portion of the drive structure 30 is mounted within the support portion 23 and extends from the opening 231 to the outside of the main body 20. A guide rail 235 is provided on the inner wall of the first receiving cavity 21 of the main body 20, guiding the drive structure 30. Please refer to [reference needed]. Figures 1 to 2 The main swing part 10 extends protrudingly along the length of the main body 20 and is mounted at one end of the main body 20. The main swing part 10 has a cylindrical structure and includes a body 11, a connector 15, and a first motor 13.

[0027] The main body 11 is a hollow cylindrical structure with an opening on one side. An installation space 110 is formed inside the main body 11 along its length (longitudinal direction). The first motor 13 is housed within the installation space 110 and is engaged and fixed to the inner wall of the main body 11. In this embodiment, the first motor 13 is a vibration motor. In this embodiment, the main body 20 and the main body 11 are made of a first material with a first hardness, i.e., the main body 20 and the main body 11 are made of a hard material.

[0028] The connector 15 is installed in the opening of the body 11 and includes a fixing portion 151 and a connecting portion 153 extending outward from one end of the fixing portion 151. The fixing portion 151 is received into the interior of the body 11 through the opening and engages with the opening of the body 11, thereby fixing the fixing portion 151 to the opening of the body 11. The connecting portion 153 has a cylindrical structure with a diameter larger than that of the fixing portion 151, thereby forming a stepped structure between the connecting portion 153 and the fixing portion 151. The end of the connecting portion 153 away from the fixing portion 151 is recessed inward to form a connecting groove 1531 for mounting the drive structure 30. The end of the connecting portion 153 away from the fixing portion 151 is fixedly connected to the body 20. In this embodiment, the connector 15 is made of a second material with a second hardness, the second hardness being less than the first hardness. The connector 15 is made of a soft material.

[0029] Please refer to the following: Figure 1 , Figures 2 to 5 The drive structure 30 is installed in the first receiving cavity 21 of the main body 20 and is connected to the connector 15, the first auxiliary swing part 50, and the second auxiliary swing part. The drive structure 30 includes a drive motor 31, a telescopic sleeve 33, a slider 35, a first transmission member 37, and a second transmission member 39.

[0030] The drive motor 31 is fixedly installed in the first receiving cavity 21 of the main body 20, and includes a telescopic part 312 that can extend and retract relative to the main body 20. The telescopic part 312 extends out from the opening of the main body 20 and engages in the connecting groove 1531, thereby connecting the telescopic part 312 to the connector 15.

[0031] The telescopic sleeve 33 is installed on the telescopic part 312 of the drive motor 31. Driven by the drive motor 31, the telescopic part 312 moves telescopically relative to the main body 20. Simultaneously, the telescopic part 312 drives the telescopic sleeve 33, which in turn drives the connecting member 15. Therefore, driven by the drive motor 31, the connecting member 15 moves telescopically relative to the main body 20. The telescopic sleeve 33 includes an engaging part 331, a fixed connecting part 332 extending outward from one end of the engaging part 331, and a driving part 334 extending outward from the end of the fixed connecting part 332 away from the engaging part 331. The engaging part 331 is cylindrical, with one end received in the connecting groove 1531 of the connecting member 15 and engaging with the opening of the connecting member 15. The other end is fixedly connected to the telescopic part 312. The engaging part 331 can drive the connecting member 15 to move telescopically. The fixed connecting part 332 extends vertically along the semi-circular edge of the engaging part 331, and its cross-section is arc-shaped. The fixed connecting part 332 is fixedly placed on the telescopic part 312 and moves together with the telescopic part 312.

[0032] The driving part 334 is located at the end of the fixed connection part 332 away from the engaging part 331, and extends upward in a direction perpendicular to the fixed connection part 332. The driving part 334 is triangular in shape, with guide parts 3342 extending from its two side walls. The guide parts 3342 are received in the guide rail 235 of the main body 20, so that under the drive of the drive motor 31, the guide parts 3342 of the telescopic sleeve 33 move linearly along the guide rail 235 of the main body 20. An inclined sliding hole 3341 is provided above the guide parts 3342 of the driving part 334. The sliding hole 3341 is an inclined hole, which gradually slopes upward from the connection point with the fixed connection part 332 toward the direction away from the fixed connection part 332.

[0033] Please refer to the following: Figures 2 to 5The slider 35 is movably disposed on the driving part 334 and can slide along the sliding hole 3341. The slider 35 includes a sliding connecting part 351 and a mounting part 353 extending vertically from the sliding connecting part 351. The sliding connecting part 351 is U-shaped and includes two first protrusions 3512 and a first rotating shaft 3513. The two first protrusions 3512 are located on both sides of the slider 35. The first rotating shaft 3513 passes through one first protrusion 3512, the sliding hole 3341, and the other first protrusion 3512 in sequence, so that a portion of the rotating shaft 3513 is received in the sliding hole 3341 and slides along the sliding hole 3341. When the telescopic part 312 extends and retracts, the guide part 3342 of the telescopic sleeve 33 moves linearly along the guide rail 235 of the main body 20. The driving part 334 of the telescopic sleeve 33 carries the slider 35 to extend and retract. At this time, the inclined surface of the sliding hole 3341 contacts the first rotating shaft 3513, and the inclined surface pushes the first rotating shaft 3513. As the slider 35 moves towards the main swing part 10 along the length direction of the main body 20, the height of the inclined surface of the sliding hole 3341 gradually increases. Therefore, the first rotating shaft 3513 gradually rises along the inclined surface and the slider 35 moves upward as a whole. Conversely, when the slider 35 moves away from the main swing part 10 along the length direction of the main body 20, the first rotating shaft 3513 gradually descends along the inclined surface and the slider 35 moves downward as a whole. Then the slider 35 slides along the sliding hole 3341 and moves up and down relative to the main body 20. The mounting portion 353 includes two second protrusions 3531 and a second rotating shaft 3533. The two second protrusions 3531 extend in the opposite direction to the two first protrusions 3512 and are offset from the two first protrusions 3512, that is, the first protrusions 3512 and the second protrusions 3531 are not located on the same plane. The second rotating shaft 3533 passes through the two second protrusions 3531.

[0034] Please refer to the following: Figures 3 to 5The first transmission member 37 and the second transmission member 39 are movably mounted on the second rotating shaft 3533. The first transmission member 37 includes a first transmission part 371 and a first shaft part 372 movably mounted on the first transmission part 371. The first transmission part 371 has an L-shaped structure, and the first shaft part 372 is rotatably mounted on one end of the first transmission part 371. The first shaft part 372 is fixedly connected to the support part 23 of the main body 20. Two first rotating parts 373 extend vertically from both sides of one end of the first transmission part 371. The two first rotating parts 373 are spaced apart and arranged parallel to each other. The two first rotating parts 373 are located between the second protrusions 3531, and the third rotating shaft 375 passes through the two first rotating parts 373, so that the two first rotating parts 373 are rotatably mounted between the second protrusions 3531. The second transmission member 39 includes a second transmission part 391 and a second shaft part 392 movably mounted on the second transmission part 391. The second transmission part 391 has an L-shaped structure. A second shaft part 392 is rotatably mounted at one end of the second transmission part 391, and the second shaft part 392 is fixedly connected to the support part 23 of the main body 20. A second rotating part 393 extends from the center of one end of the second transmission part 381 and is located between the two first rotating parts 373. A groove 3831 is formed at one end of the second rotating part 393. The third rotating shaft 375 passes through the groove 3831 of the second rotating part 393, so that the second transmission member 39 is movably mounted between the second protrusions 3531. In this embodiment, the third rotating shaft 375 passes sequentially through one second protrusion 3531, one first rotating part 373, the groove 3831 of the second rotating part 393, another first rotating part 373, and another second protrusion 3531, so that the second transmission member 39 and the first transmission member 37 swing towards each other through the third rotating shaft 375, and thus the second transmission member 39 and the first transmission member 37 can clamp together.

[0035] Please refer to the following: Figures 1 to 2 The first and second auxiliary swing portions 50 and 2 extend protruding along the width direction of the main body 20, are mounted on the support portion 23 of the main body 20, and are spaced apart from each other, located on the same side of the main swing portion 10. The first and second auxiliary swing portions 50 and 2 are rod-shaped, each including a sleeve portion 51 and a second motor 73. The second motor 73 is housed within the sleeve portion 51, which is sleeved onto the first transmission portion 371 of the corresponding first transmission member 37 and the second transmission portion 391 of the corresponding second transmission member 39. In this embodiment, the sleeve portion 51 is made of a second material with a second hardness. The sleeve portion 51 is also made of a soft material.

[0036] Please refer to the following: Figure 1The swing drive device 100 also includes a covering member 101, which covers the main body 20, the first auxiliary swing part 50, the second auxiliary swing part 70, and the main swing part 10. The covering member 101 is made of a third material with a third hardness, which is less than the second hardness. The covering member 101 is made of a soft material.

[0037] In this embodiment, the second hardness is less than the first hardness, and the third hardness is less than the second hardness. That is, the main body 20 and the body 11 of the first hardness are made of hard material, the connecting member 15 and the sleeve portion 51 of the second hardness are made of soft material, and the covering member 101 of the third hardness is made of a soft material that is softer than the material of the connecting member 15 and the sleeve portion 51.

[0038] The control circuit board 101 is connected to the drive motor 31, the first motor 60, the second motor 53, and 73 to control the drive motor 31, the first motor 60, the second motor 53, and 73.

[0039] When the swing drive device 100 is working, the first motor 60 and the drive motor 31 are started under the control of the control circuit board 101. The first motor 60 vibrates within the main swing section 20. At the same time, driven by the drive motor 31, the telescopic part 312 moves telescopically relative to the main body 20. At this time, the telescopic part 312 drives the telescopic sleeve 33, and the telescopic sleeve 33 drives the connecting piece 15. Therefore, the connecting piece 15 can move telescopically. Simultaneously, the guide portion 3342 of the telescopic sleeve 33 moves linearly along the guide rail 235 of the main body 20, and the slider 35 reciprocates along with the telescopic sleeve 33. The slider 35 also reciprocates up and down along the sliding hole 3341 relative to the main body 20. The second rotating shaft 3533 installed on the slider 35 also pulls and pushes the two first rotating portions 373 of the first transmission member 37 and the second rotating portion 393 of the second transmission member 39 up and down. Thus, when the two first rotating portions 373 of the first transmission member 37 and the second rotating portion 393 of the second transmission member 39 are pulled downward, the first transmission member 37 and the second transmission member 39 move relative to each other and move closer. When the two first rotating portions 373 of the first transmission member 37 and the second rotating portion 393 of the second transmission member 39 are pushed upward, the first transmission member 37 and the second transmission member 39 move in opposite directions and move away from each other. The clamping motion is achieved through the opposing swing motion of the first transmission member 37 and the second transmission member 39. In addition, the control circuit board 101 controls the second motors 53 and 73 to vibrate within the secondary swing section, so that the first secondary swing section 50 and the second secondary swing section can vibrate and move simultaneously while being clamped together.

[0040] In one embodiment, the length of the main swing part 30 ranges from 3cm to 30cm, and specific examples include 3cm, 5cm, 8cm, 10cm, 15cm, 20cm, 25cm, 30cm, etc., which are not limited here.

[0041] Compared with the prior art, the swing drive device 100 of this utility model can drive the first secondary swing part 50 and the second secondary swing part. When in use, the product can have multiple secondary swing parts so that the user can obtain a better massage effect.

[0042] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
