[0016] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. One or more embodiments of this utility model are exemplarily shown in the drawings to enable a more accurate and thorough understanding of the disclosed technical solutions. However, it should be understood that this utility model can be implemented in many different forms and is not limited to the embodiments described below.
[0017] Figure 1-3 The diagram shows a specific embodiment of the telescopic swing mechanism of this utility model. The telescopic swing mechanism 100 includes a first actuating component 20, a second actuating component 30, a first driving assembly 40, and a second driving assembly 50. Figure 2 , Figure 9 As shown, the first drive assembly 40 is connected to the first actuating component 20 and is used to drive the first actuating component 20 to move between the first position P1 and the second position P2; the second drive assembly 50 is connected to the second actuating component 30 and is used to drive the second actuating component 30 to swing between the third position P3 and the fourth position P4.
[0018] The telescopic swing mechanism 100 includes at least a first state and a second state during use, wherein, in the first state, see... Figure 9-10 The second actuating component 30 swings to the third position, abutting against the first actuating component 20 which has moved to the first position; in the second state, see... Figure 2-3 The second actuating component 30 swings to the fourth position, separating from the first actuating component 20 which has moved to the second position. Preferably, both the first actuating component 20 and the second actuating component 30 of the telescopic swing mechanism 100 are made of flexible materials, such as silicone, and have a certain elastic deformation capability.
[0019] In one specific embodiment, such as Figure 4-6As shown, the first actuating component 20 is generally cylindrical in structure, with an internally formed, roughly cylindrical, receiving space 22. When the first actuating component 20 is driven, it can move along the first axis A1 (see...). Figure 5 The first actuating component 20 reciprocates between a first position P1 and a second position P2, wherein the first axis A1 is preferably the central axis of the first actuating component 20. The first actuating component 20 has a first end 24 and a second end 25 that are axially opposite each other, wherein the first end 24 is configured as an open end and the second end 25 is configured as a closed end.
[0020] The second actuating member 30 is disposed axially outside the second end 25 of the first actuating member 20, relatively close to the second end 25 and away from the first end 24. When the second actuating member 30 is driven, it can rotate around the second axis A2 (see...). Figure 8 It swings between the third position P3 and the fourth position P4, striking the second end 25 of the first actuating component 20. The second axis A2 is set at an angle relative to the first axis A1, preferably perpendicular to the first axis A1.
[0021] Reference Figure 1-3 In this embodiment, the first axis A1 extends along a first direction, such as the X direction; the second axis A2 extends along a second direction, such as the Y direction. In a third direction, such as the Z direction, the first axis A1 and the second axis A2 are preferably at different heights. In three-dimensional space, axes A1 and A2 are perpendicular but do not intersect. Thus, the second actuating component 30 swings in the XZ plane, and the center of its swing path deviates from the first axis A1 extending in the X direction, wherein the third position P3 is relatively close to the first axis A1, and the fourth position P4 is relatively far away from the first axis A1.
[0022] like Figure 4-6 As shown, in one specific embodiment, the first drive assembly 40 includes a first motor 42, a slider 44, and a first transmission assembly connected between the first motor 42 and the slider 44. The first motor 42 may be a rotary motor, and its first output shaft 421 is capable of rotating at an appropriate speed. Preferably, the first motor 42 is a geared motor.
[0023] The sliding member 44 is connected to the first actuating component 20, and preferably sleeved on the first end 24 of the first actuating component 20. In this embodiment, the outer wall surface of the first end 24 of the first actuating component 20 is recessed to form an annular groove 241, and the sliding member 44 is embedded in the annular groove 241. Preferably, an ear 441 is formed on the outer wall of the sliding member 44, and a guide rod 443 is movably inserted through the ear 441. The guide rod 443 is fixedly disposed in the telescopic swing mechanism 100, extends parallel to the first axis A1, and guides the reciprocating movement of the first actuating component 20, thereby making its movement more stable.
[0024] The first transmission assembly includes a conversion component 46, such as a first shaft 461 and a first slide groove 463 that cooperate with each other. The first shaft 461 is connected to the first motor 42 and is driven to revolve around a third axis A3, which extends along a third direction, such as the Z direction, and is perpendicular to the first axis A1. The first slide groove 463 is a strip-shaped groove extending along a second direction, such as the Y direction, and is perpendicular to both the third axis A3 and the first axis A1. The first slide groove 463 can be directly formed on the sliding member 44, or it can be formed separately and then assembled onto the sliding member 44.
[0025] When the first shaft 461 is inserted into the first slide groove 463, the two slide in the second direction and are fixed in other directions. When the first shaft 461 is driven to revolve around the third axis A3, displacement occurs in both the first and second directions. The displacement of the first shaft 461 in the second direction causes it to slide along the first slide groove 463, and the displacement in the first direction causes it to push the slider 44 to move in the first direction. In this way, the rotational motion of the first motor 42 is converted into the reciprocating motion of the slider 44 in the first direction, realizing the conversion of the motion mode.
[0026] The first transmission assembly may further include a steering assembly 48, such as two meshing helical gears 481 and 483, wherein the first helical gear 481 is mounted on the first output shaft 421, and the first shaft 461 is eccentrically mounted on the second helical gear 483. The axis of revolution of the first shaft 461, i.e., the third axis A3, is preferably the central axis of the second helical gear 483. Through the engagement of the two helical gears 481 and 483, the first shaft 461 and the first output shaft 421 are at an angle to each other, preferably perpendicular to each other, thereby changing the direction of power transmission. This facilitates the assembly of the first motor 42.
[0027] In some embodiments, other forms of steering components, such as worm gears, may be present between the first output shaft 421 and the first shaft 461 of the first motor 42. Alternatively, the first output shaft 421 and the first shaft 461 of the first motor 42 may be configured in the same direction, omitting the steering component 48.
[0028] In some embodiments, the conversion component 46 may also take other forms, such as a gear and rack, wherein the gear is connected to the first output shaft 421 of the first motor 42 and the rack is connected to the slider 44, which can also convert the rotational motion of the first motor 42 into the reciprocating motion of the slider 44.
[0029] like Figure 7-8As shown, in one specific embodiment, the second drive assembly 50 includes a second motor 52, a swing member 54, and a second transmission assembly connected between the second motor 52 and the swing member 54. The second motor 52 may be a rotary motor, and its second output shaft 521 is capable of rotating at an appropriate speed. Preferably, the second motor 52 is a geared motor.
[0030] The swing member 54 is rotatably disposed in the telescopic swing mechanism 100. One end of the swing member 54 extends into the second actuating component 30, and the other end is connected to the second motor 52 via the second transmission assembly. In this embodiment, the swing member 54 includes a first swing arm 541 and a second swing arm 543 hinged to each other. The middle portion of the first swing arm 541 is rotatably disposed in the telescopic swing mechanism 100 via a first pivot 545, and the middle portion of the second swing arm 543 is rotatably disposed in the telescopic swing mechanism 100 via a second pivot 547. The first swing arm 541 and the second swing arm 543 are arranged in parallel and spaced apart, both extending along the second direction.
[0031] The second transmission assembly includes a conversion component 56, such as a second shaft 561 and a second slide groove 563 that cooperate with each other. The second slide groove 563 is a strip-shaped groove extending along a second direction, such as the Y direction. The second shaft 561 is driven to revolve around a fourth axis A4, which is preferably perpendicular to the second slide groove 563. The second shaft 561 is inserted into the second slide groove 563, and the two are slidably engaged in the second direction and fixedly engaged in other directions. When the second shaft 561 revolves around the fourth axis A4, its displacement in the second direction causes it to slide relative to the second slide groove 563, and its displacement in the direction perpendicular to the second slide groove 563 can push the groove wall to move accordingly.
[0032] In this embodiment, the outer end of the first swing arm 541 (i.e., the end opposite to the second swing arm 543) is fixedly inserted into the second actuating component 30, and the outer end of the second swing arm 543 (i.e., the end opposite to the first swing arm 541) forms the second sliding groove 563. When the second motor 52 drives the second shaft 561 to rotate, it drives the second swing arm 543 to rotate around the second pivot 547, thereby causing the first swing arm 541 to rotate around the first pivot 545. The swing directions of the first swing arm 541 and the second swing arm 543 are opposite. Ultimately, the second actuating component 30 swings around the first pivot 545. In this embodiment, the swing axis of the second actuating component 30, i.e., the second axis A2, is the central axis of the first pivot 545.
[0033] With the cooperation of the first swing arm 541 and the second swing arm 543, the second shaft 561 can be inclined or vertically arranged relative to the first pivot 545 and the second pivot 547, thus making the assembly of the second motor 52 more flexible and convenient. In this embodiment, the second shaft 561 is eccentrically arranged on the wheel 565, and the two are preferably an integral structure. The wheel 565 is sleeved on the second output shaft 521 of the second motor 52, and the fourth axis A4 can be the central axis of the second output shaft 521 and / or the wheel 565. In other embodiments, other structures, such as steering components, can also be configured between the second shaft 561 and the second motor 52.
[0034] During use, the distance between the moving parts 20 and 30 of the telescopic swing mechanism 100 continuously changes. When the first actuating part 20 moves toward the first position P1, its second end 25 gradually approaches the second actuating part 30; when the second actuating part 30 swings toward the third position P3, its end gradually approaches the second end 25 of the first actuating part 20. Conversely, when the first actuating part 20 moves toward the second position P2, its second end 25 gradually moves away from the second actuating part 30; when the second actuating part 30 swings toward the fourth position P4, its end gradually moves away from the second end 25 of the first actuating part 20.
[0035] like Figure 9-10 As shown, the first actuating component 20 moves to the first position P1 and the second actuating component 30 swings to the third position P3, with the end of the second actuating component 30 abutting against the second end 25 of the first actuating component 20, and the telescopic swing mechanism 100 is in the first state. Preferably, in the first state, the second end 25 of the first actuating component 20 undergoes elastic deformation. In the direction shown in the figure, the second end 25 is compressed and bends downward. During this process, the second actuating component 30 can undergo a certain amount of elastic deformation.
[0036] It should be noted that when the second actuating component 30 swings to near the third position P3, its end can come into contact with the second end 25 of the first actuating component 20 that has moved to near the first position P1. Afterward, as the second actuating component 30 swings further and the first actuating component 20 moves further, the first actuating component 20 and the second actuating component 30 slide relative to each other and undergo elastic deformation due to mutual interference. In particular, the second end 25 of the first actuating component 20 is bent and tilted at a certain angle until the first actuating component 20 reaches the first position P1 and the second actuating component 30 reaches the third position P3.
[0037] Subsequently, the second actuating component 30 swings in the opposite direction, and the first actuating component 20 moves in the opposite direction. The two gradually separate and recover their deformation until the first actuating component 20 reaches the second position P2 and the second actuating component 30 reaches the fourth position P4. The telescopic swing mechanism 100 is in the second state, as shown below. Figure 2-3 As shown. In the initial stage of this process, the first actuating component 20 and the second actuating component 30 remain in a state of mutual contact, and the second end 25 of the first actuating component 20 gradually rebounds. In this way, the second end 25 of the first actuating component 20 can swing within a small range.
[0038] It should be noted that the first state can last for a certain duration, and is not limited to the instant when the second actuating component 30 is in the third position and the first actuating component 20 is in the first position; the second state can also last for a certain duration, and is not limited to the instant when the second actuating component 30 is in the fourth position and the first actuating component 20 is in the second position. Preferably, the duration of the telescopic swing mechanism 100 in the first state is much shorter than the duration of its second state. Overall, the second actuating component 30 continuously strikes the second end 25 of the first actuating component 20 through its swing.
[0039] The aforementioned telescopic swing mechanism 100 is equipped with two actuating parts 20 and 30. During use, the two actuating parts 20 and 30 move and swing respectively. The movement path of the first actuating part 20 intersects with the swing path of the second actuating part 30. Thus, during the movement of the first actuating part 20, the swinging second actuating part 30 can tap the first actuating part 20. The telescopic swing mechanism 100 of this application can be applied to a massage device. The actuating parts 20 and 30 can serve as two massage parts. The parts that need to be massaged, such as the arm, can be inserted into the receiving space 22 of the first actuating part 20. The movement of the first actuating part 20 and the tapping of the second actuating part 30 relax the massaged parts. Moreover, the interaction between the first actuating part 20 and the second actuating part 30 can cause the massaged parts to bend, which is particularly beneficial for rehabilitation training of the wrist joint, finger joint, etc.
[0040] Figure 3 , Figure 10 In the illustrated embodiment, the second end 25 of the first actuating component 20 is a closed end, which can better enclose the front end of the massaged part, such as a fingertip, located within the receiving space 22. In some embodiments, the second end 25 of the first actuating component 20 can be an open end, allowing the front end of the massaged part to be exposed, so that the second actuating component 30 can directly pat the exposed massaged part during the oscillation process. Preferably, the second actuating component 30 is generally tongue-shaped, and its surface facing the second end 25 is a convex arc surface, which can fully contact its spherical end surface when patting the second end 25.
[0041] In some embodiments, such as Figure 1 , Figure 4 As shown, a pleat 26 is formed in the axial center of the first actuating component 20. The pleat 26 can be a single loop or multiple loops. The receiving space 22 at the pleat 26 has a larger diameter, which can further enhance the elastic deformation capability of the first actuating component 20. It can not only adapt to the different sizes of the massaged parts of different users, but more importantly, when subjected to the force of the second actuating component 30, the bending deformation capability can be enhanced by the pleat 26, so that the swing amplitude of the front end of the massaged part can be improved to a certain extent.
[0042] In some embodiments, such as Figure 3-5 As shown, the inner wall of the first actuating component 20 has protrusions 27. These protrusions 27 can be columnar, dot-shaped, or block-shaped, and their size, number, and arrangement can be adjusted as needed. When the first actuating component 20 reciprocates, its inner wall rubs against the massaged area, producing a kneading effect. The protrusions 27 effectively enhance the friction on the massaged area. In the illustrated embodiment, the protrusions 27 are located on the inner wall of the first end 24 of the first actuating component 20. In other embodiments, protrusions can also be provided on the inner wall of the second end 25.
[0043] like Figure 3 As shown, the first actuating component 20 may embed a vibration motor 60, which can be single or multiple. Preferably, the first end 24 of the first actuating component 20 has a greater wall thickness than the second end 25, and the vibration motor 60 is embedded in the first end 24. Similarly, the second actuating component 30 may embed a vibration motor 62, the number of which can be set as needed. Thus, the telescopic swing mechanism 100 of this application can output power through movement and swinging, and can also output power through vibration.
[0044] like Figure 2 , Figure 3 As shown, the telescopic swing mechanism 100 of this application also includes a battery 70, which serves as the power source for the entire telescopic swing mechanism 100 and is electrically connected to the first motor 42, the second motor 52, and the vibration motors 60 and 62. In this embodiment, the first output shaft 421 of the first motor 42 and the second output shaft 521 of the second motor 52 are oriented opposite to each other and inclined to each other. Preferably, the included angle α between them is an obtuse angle, which facilitates connection with the first actuating component 20 and the second actuating component 30. A space is formed between the first motor 42 and the second motor 52 for installing the battery 70, thus making the overall structure of the telescopic swing mechanism 100 more compact and its overall size smaller.
[0045] In some embodiments, the telescopic swing mechanism 100 of this application further includes a control circuit board, and the battery 70 is preferably electrically connected to the first motor 42, the second motor 52, and the vibration motors 60 and 62 via the control circuit board. The control circuit board is used to control the operation of the telescopic swing mechanism 100, such as controlling the rotation speed and direction of the first motor 42 and the second motor 52, and controlling the amplitude and frequency of the vibration motors 60 and 62. Preferably, the control circuit board 82 is used to ensure that the period of reciprocating movement of the first actuating component 20 is equivalent to the period of reciprocating swing of the second actuating component 30, and that when the first actuating component 20 moves to the first position P1, the second actuating component 30 swings to the third position P3, producing a slapping effect.
[0046] It should be noted that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these should all fall within the protection scope of the present invention.
