Figure 3 yes Figure 1 The present invention provides a telescopic rotating mechanism 100, which may include a housing 10, a driving member 20, a transmission assembly 30, and a switching mechanism 40. The housing 10 is provided with a receiving chamber 12, and the driving member 20, the transmission assembly 30, and the switching mechanism 40 are arranged in the receiving chamber 12 for protecting the driving member 20, the transmission assembly 30, and the switching mechanism 40.

[0029] Specifically, the driving member 20 has a rotating output shaft 22, and the transmission assembly 30 has a transmission rod 32, and the axis of the transmission rod 32 is parallel to the axis of the rotating output shaft 22; the adapter mechanism 40 is located on the same side of the driving member 20 and the transmission assembly 30, and is connected to the rotating output shaft 22 and the transmission assembly 30, and the adapter mechanism 40 is used to drive the transmission rod 32 to move along the axial direction of the transmission rod 32 under the drive of the rotating output shaft 22.

[0030] The embodiment of the present invention arranges the axial direction of the rotating output shaft 22 of the driving member 20 and the axial direction of the transmission rod 32 in parallel, and arranges the adapter mechanism 40 on the same side of the driving member 20 and the transmission assembly 30, that is, it is arranged along the axial direction perpendicular to the rotating output shaft 22 of the driving member 20, and utilizes the adapter mechanism 40 to convert the rotation of the driving member 20 into the translation of the transmission rod 32 along the axial direction, so that on the one hand, the transmission rod 32 can be driven to move along the axial direction, and on the other hand, the length of the shell 10 along the axial direction of the rotating output shaft 22 can be shortened, so that the structure of the telescopic rotating mechanism 100 is more compact and the required installation space is small, so as to expand the application range of the telescopic rotating mechanism 100.

[0031] Among them, Figure 3 As shown, the housing 10 may include a first housing 14 and a second housing 16 that are detachably connected, so as to facilitate maintenance of the driving member 20, the transmission assembly 30, and the switching mechanism 40 disposed in the accommodating cavity 12. The first housing 14 and the second housing 16 may be connected by fasteners such as screws, or may be connected by hooks and buckles, etc., which is not specifically limited in the embodiment of the present application.

[0032] Optionally, the driving member 20 can be configured as a rotary motion mechanism such as a motor or an electric cylinder. When a motor is used as the driving member 20, the output shaft of the motor can be used as the rotating output shaft 22. Figure 3 As shown, the adapter mechanism 40 is located on the same side of the driving member 20 and the transmission assembly 30, which specifically means that the adapter mechanism 40 is located on the left side of the driving member 20 along the axial direction of the rotating output shaft 22, and the adapter mechanism 40 is located on the left side of the transmission assembly 30 along the axial direction of the transmission rod 32. It can be understood that the adapter mechanism 40 can also be arranged on the right side of the driving member 20 and the transmission rod 32 along the axial direction of the rotating output shaft 22.

[0033] Furthermore, if Figure 2 and Figure 3 As shown, the transfer mechanism 40 includes a gearbox 42, a first connecting rod 44 and a second connecting rod 46.

[0034] Among them, the gearbox 42 is used to reduce the speed of the rotating output shaft 22 of the motor, thereby reducing the reciprocating extension rate of the transmission rod 32 to enhance the user experience. The output end of the gearbox 42 in the present application is located in two directions perpendicular to each other to facilitate the connection of the drive member 20 and the transmission assembly 30. The gearbox 42 can, for example, adopt a worm gear transmission structure to increase the output torque of the gearbox 42. The gearbox 42 can also adopt a multi-stage reduction gear structure, which is not specifically limited in the embodiments of the present application.

[0035] Optionally, the first connecting rod 44 and the second connecting rod 46 can be directly connected to each other by a rotating shaft, and the second connecting rod 46 and the transmission assembly 30 can be directly connected to each other by a rotating shaft. However, when connecting in this manner, it is necessary to ensure that the first connecting rod 44 and the second connecting rod 46 have high processing accuracy and good coaxiality, thereby increasing the processing cost and easily causing wear and damage to the rotating shaft after long-term use.

[0036] Therefore, in this embodiment, if Figure 2 and Figure 3 As shown, the switching mechanism 40 may further include a first bearing 41, a second bearing 43, a first rotating shaft 45, and a second rotating shaft 47. The output end of the gearbox 42 is fixedly connected to the first end of the first connecting rod 44, and is used to drive the first connecting rod 44 to rotate around the output end of the gearbox 42. The second end of the first connecting rod 44 is rotatably connected to the first end of the second connecting rod 46 through the first bearing 41 and the first rotating shaft 45, and the second end of the second connecting rod 46 is rotatably connected to the transmission assembly 30 through the second bearing 43 and the second rotating shaft 47.

[0037] Specifically, a first rotating shaft 45 is provided on the second end of the first connecting rod 44, and the axial direction of the first rotating shaft 45 is along the extension direction of the output end of the gearbox 42. A first connecting hole 462 is provided on the first end of the second connecting rod 46, and the first bearing 41 is interference-fitted in the first connecting hole 462. The first rotating shaft 45 is inserted into the first bearing 41 to rotatably connect the second end of the first connecting rod 44 and the first end of the second connecting rod 46. A second connecting hole 464 is provided on the second end of the second connecting rod 46, and the second rotating shaft 47 is connected to the transmission assembly 30. The second bearing 43 is interference-fitted in the second connecting hole 464, and the second rotating shaft 47 is inserted into the second bearing 43 to rotatably connect the second end of the second connecting rod 46 and the transmission assembly 30.

[0038] It can be understood that in other embodiments, a first connecting hole 462 can be opened on the second end of the first connecting rod 44, the first bearing 41 is interference-fitted in the first connecting hole 462, a first rotating shaft 45 is provided on the first end of the second connecting rod 46, the axial direction of the first rotating shaft 45 is along the extension direction of the output end of the gearbox 42, and the first rotating shaft 45 is inserted in the first bearing 41 to rotatably connect the second end of the first connecting rod 44 and the first end of the second connecting rod 46. A second rotating shaft 47 can be provided on the second end of the second connecting rod 46, a second connecting hole 464 is opened on the transmission assembly 30, the second bearing 43 is interference-fitted in the second connecting hole 464, and the second rotating shaft 47 is inserted in the second bearing 43 to rotatably connect the second end of the second connecting rod 46 and the transmission assembly 30.

[0039] Furthermore, if Figure 4 As shown, Figure 4 yes Figure 3 Schematic diagram of the three-dimensional structure of the first connecting rod in the embodiment. The first connecting rod 44 may include, for example, a first connecting portion 442, a second connecting portion 444, and a third connecting portion 446 that are bent and connected. The first connecting portion 442 and the third connecting portion 446 are arranged in parallel and spaced apart. The first connecting portion 442 is fixedly connected to the output end of the gearbox 42, and the second connecting portion 444 is rotatably connected to the second connecting rod 46. In this way, the first connecting portion 442 and the second connecting rod 46 can be spaced apart to reduce the contact area between the first connecting rod 44 and the second connecting rod 46, thereby reducing wear and friction noise.

[0040] Furthermore, if Figure 2 and Figure 3 As shown, the transmission assembly 30 further includes a connecting seat 34 and a fixing seat 36 disposed in the accommodating chamber 12, wherein the connecting seat 34 is connected to the second end of the second connecting rod 46 and the first end of the transmission rod 32, and is used to connect the transmission rod 32 with the second connecting rod 46 to drive the transmission rod 32 to move. The fixing seat 36 is arranged relative to the connecting seat 34 along the axial direction of the transmission rod 32, and a guide hole 362 is provided on the fixing seat 36, and the second end of the transmission rod 32 can be slidably penetrated in the guide hole 362 to guide the transmission rod 32, thereby enabling the transmission rod 32 to move in a straight line direction.

[0041] like Figure 2 and Figure 5 As shown, Figure 5 yes Figure 3Schematic diagram of the exploded structure of the connecting seat in FIG. The connecting seat 34 includes a connecting shell 342, a cover body 344, a third bearing 346 and a baffle 348. The connecting shell 342 is rotatably connected to the second end of the second connecting rod 46. The cover body 344 is connected to the connecting shell 342 and is surrounded by the connecting shell 342 to form a mounting cavity 341. The cover body 344 is provided with an avoidance hole 345. The third bearing 346 and the baffle 348 are arranged in the mounting cavity 341 along the axial direction of the transmission rod 32. The outer contour size of the third bearing 346 is larger than the cross-sectional size of the avoidance hole 345. The cross-sectional size of the baffle 348 is larger than the inner contour size of the third bearing 346. The first end of the transmission rod 32 is passed through the avoidance hole 345, the third bearing 346 and the baffle 348, and the first end of the transmission rod 32 is limited in the mounting cavity 341.

[0042] Specifically, two parallel and spaced baffles 343 are protruding from one side of the connecting shell 342 facing the second connecting rod 46, and a third connecting hole 347 is provided on the baffle 343. The second end of the second connecting rod 46 is inserted between the two baffles 343, and the second rotating shaft 47 is inserted into the third connecting hole 347. In this way, by setting the second connecting rod 46 between the two baffles 343, the connecting shell 342 can be evenly stressed, thereby improving the movement stability of the transmission rod 32 connected to the connecting shell 342.

[0043] Among them, the connection shell 342 is provided with an installation space on one side facing the cover body 344, and the cover body 344 is provided with an installation space on one side facing the connection shell 342. When the connection shell 342 and the cover body 344 are connected to each other, the installation spaces on both sides are connected to form the installation cavity 341. The connection shell 342 and the cover body 344 can be connected by fasteners such as screws, can be connected by buckles and hooks, can be connected by bonding, etc., and the embodiment of the present application does not make specific limitations.

[0044] like Figure 6 As shown, Figure 6 yes Figure 3 The fixed seat 36 includes a seat body 364 and a stop pin 366. The guide hole 362 is provided on the seat body 364. The stop pin 366 is connected to the seat body 364 and protrudes from the side wall of the guide hole 362. The transmission rod 32 is provided with a spiral groove 322 ( Figure 3 As shown in FIG. 3 , the limit pin 366 is inserted into the spiral groove 322 to drive the transmission rod 32 to rotate through the interaction between the limit pin 366 and the spiral groove 322.

[0045] Specifically, when the transmission rod 32 telescopes relative to the fixed seat 36 under the action of the second connecting rod 46, the spiral groove 322 moves relative to the limit pin 366, and the side wall of the spiral groove 322 abuts against the limit pin 366. Under the limitation of the limit pin 366, the transmission rod 32 rotates simultaneously during the telescopic process.

[0046] The limiting pin 366 may be integrally formed with the seat body 364, or the limiting pin 366 may be detachably connected to the seat body 364. For example, in this embodiment, the seat body 364 is provided with a through hole 368, the limiting pin 366 is mounted on the seat body 364 and extends into the through hole 368, and the connecting piece 360 ​​is connected to the seat body 364 and presses the limiting pin 366 to fix the limiting pin 366 on the seat body 364.

[0047] The number of the limiting pin 366 can be one, and the number of the corresponding spiral groove 322 is also one, and one limiting pin 366 is inserted into the spiral groove 322. Figure 6 As shown, there are two stop pins 366, and the two stop pins 366 are arranged on opposite sides of the guide hole 362 along the diameter direction of the guide hole 362. Alternatively, the number of the stop pins 366 and the spiral groove 322 can also be three, four, etc., and the plurality of stop pins 366 can be evenly spaced around the circumference of the guide hole 362, so that not only can the force of the stop pins 366 on the transmission rod 32 be increased, but also the force on the transmission rod 32 can be evenly applied, so as to improve the stability of the movement.

[0048] like Figure 7 and Figure 8 As shown, Figure 7 is a schematic cross-sectional view of the telescopic rotating mechanism 200 in the second embodiment of the present invention, Figure 8 yes Figure 7 Schematic diagram of the exploded structure of the telescopic rotating mechanism 200 in the embodiment. The structure of the telescopic rotating mechanism 200 in this embodiment is substantially the same as that of the telescopic rotating mechanism 100 in the above embodiment, except that the adapter mechanism 140 includes a gearbox 42, a third connecting rod 142 and a connecting plate 144, the output shaft of the gearbox 42 is connected to the third connecting rod 142 for driving the third connecting rod 142 to rotate, the connecting plate 144 is slidably connected to the third connecting rod 142 and fixedly connected to the transmission assembly 30, so that the rotational motion of the gearbox 42 can be converted into the telescopic motion of the transmission rod 32, and the structure of the adapter mechanism 40 can be simplified, further reducing the volume of the telescopic rotating mechanism 200.

[0049] In this embodiment, if Figure 7 and Figure 8As shown, a slider 146 is provided on the third connecting rod 142, and the extension direction of the slider 146 is along the extension direction of the output end of the gearbox 42. A slide groove 148 is provided on the connecting plate 144, and the extension direction of the slide groove 148 is perpendicular to the axial direction of the transmission rod 32. The slider 146 is slidably arranged in the slide groove 148. When the output end of the gearbox 42 drives the third connecting rod 142 to rotate, the slider 146 arranged on the third connecting rod 142 will move relative to the slide groove 148, and the slider 146 can move along the extension direction of the slide groove 148. The movement of the slider 146 along the axial direction of the transmission rod 32 will drive the connecting plate 144 to move along the axial direction of the transmission rod 32, and then drive the transmission assembly 30 to move along the axial direction of the transmission rod 32, so as to realize the telescopic movement of the transmission assembly 30.

[0050] Among them, Figure 8 As shown, the cross-sectional shape of the connecting plate 144 can be set to a trapezoid, a triangle, etc., and the slide groove 148 can be set on the side of the connecting plate 144 with a longer length, and the side of the connecting plate 144 with a shorter length can be connected to the transmission assembly 30, so as to make full use of the space on the connecting plate 144 and reduce the volume of the connecting plate 144, making the structure of the adapter mechanism 40 more compact.

[0051] like Fig. 9 As shown, Fig. 9 The third embodiment differs from the second embodiment in that the adapter mechanism 140 further includes a guide structure, and the connecting plate 144 is connected to the housing 10 via the guide structure to increase the stability of the connecting plate 144 in movement.

[0052] Specifically, the guide structure includes a guide seat 143 arranged on the connecting plate 144 at intervals and a guide rod 145 fixed on the housing 10, and the guide seat 143 is slidably sleeved on the guide rod 145. The first housing 14 of the housing 10 is provided with a first groove 141, and the second housing 16 is provided with a second groove 161 and a retaining wall 162 at a position corresponding to the first groove 141. The inner wall of the second housing 16 is also provided with a fixing column 163, and the fixing column 163 is provided with a first shaft hole 164, and the fixing column 164 and the second groove 161 are arranged in a straight line. When the first housing 14 and the second housing 16 are assembled together, the first groove 141 and the second groove 161 surround the second shaft hole, and the two ends of the guide rod 145 are respectively installed in the first shaft hole 164 and the second shaft hole, and the retaining wall 162 is used to limit the guide rod 145.

[0053] exist Fig. 9In the embodiment shown, the number of mutually cooperating guide seats 143 and guide rods 145 is two groups spaced apart from each other. It is understandable that in other embodiments, the number of mutually cooperating guide seats 143 and guide rods 145 can be one group or three groups, four groups, etc. spaced apart from each other, which is not specifically limited in the embodiment of the present application.

[0054] Based on the above telescopic rotating mechanism (100, 200, 300), the present application also provides a massager 00, such as Fig.10 As shown, Fig.10 : is a schematic diagram of the three-dimensional structure of a massager in an embodiment of the present application. The massager 00 includes a massage piece 400 and a telescopic rotating mechanism (100, 200, 300), and the massage piece 400 is detachably connected to the transmission rod 32 of the telescopic rotating mechanism (100, 200, 300) to move under the drive of the transmission rod 32. By detachably connecting the massage piece 400 and the transmission rod 32, it is not only convenient to clean and maintain the massage piece 400, but also possible to use the telescopic rotating mechanism (100, 200, 300) to adapt different massage pieces 400, so as to better massage different parts, thereby improving the user experience.

[0055] The massage member 400 is used to contact with a part of the human body, and can be extended and / or rotated under the drive of the transmission rod 32 to massage the human body. The shape of the massage member 400 varies according to different products and parts of the human body to be massaged. It can be a columnar, claw-shaped or other shape, which is not limited here.

[0056] In summary, the above-mentioned telescopic rotation mechanism (100, 200, 300) is achieved by arranging the axial direction of the rotating output shaft 22 of the driving member 20 and the axial direction of the transmission rod 32 in parallel, and arranging the adapter mechanism 40 on the same side of the driving member 20 and the transmission assembly 30, that is, arranging it along the axial direction perpendicular to the rotating output shaft 22 of the driving member 20, and utilizing the adapter mechanism 40 to convert the rotation of the driving member 20 into the translation of the transmission rod 32 along the axial direction, thereby, on the one hand, driving the transmission rod 32 to move along the axial direction, and on the other hand, shortening the length of the shell 10 along the axial direction of the rotating output shaft 22, so that the structure of the telescopic rotation mechanism (100, 200, 300) is more compact, and the required installation space is small, so as to expand the application range of the telescopic rotation mechanism 100.

[0057] The above are merely embodiments of the present invention. It should be pointed out that, for those skilled in the art, improvements can be made without departing from the creative concept of the present invention, but these all fall within the protection scope of the present invention.
