The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] like Figures 1 to 7 As shown, a serpentine rocking motor is characterized by comprising a drive motor 1.

[0037] Reduction gear 2 is connected to the output end of drive motor 1;

[0038] The spiral shaft 3 is connected to the output end of the reduction gear 2, and the drive motor 1 drives the spiral shaft 3 to rotate through the reduction gear 2.

[0039] The first connecting seat 4 is fixed on the outside of the reduction gear 2. The middle part is provided with a first through hole 41 through which the spiral shaft 3 passes, and the top is provided with a first rotating boss 42. The first rotating boss 42 is provided with a first rotating hole 43.

[0040] The connecting bone 5 has several connecting grooves 51 through which the spiral shaft 3 passes in the middle. The lower side of the connecting bone 5 has an arc-shaped groove 52 corresponding to the first rotating boss 42. The upper side of the connecting bone 5 has an upper connecting boss 53 corresponding to the arc-shaped groove 52. The lower side of the connecting bone 5 has a lower connecting boss 54. The upper connecting boss 53 and the lower connecting boss 54 have connecting holes 55. The upper connecting boss 53 and the lower connecting boss of adjacent connecting bones 5 are rotatably connected through the connecting holes 55 to form a serpentine body. The connecting bone 5 at the bottom of the serpentine body is rotatably connected to the first rotating boss 42 of the first connecting seat 4 at the position of the arc-shaped groove 52.

[0041] Under the action of the drive motor 1, the spiral shaft 3 rotates. The spiral shaft 3 passes through the inner side of the connecting bone 5. As the spiral shaft 3 rotates, the outer connecting bone 5 will rotate under the action of the spiral shaft 3. This causes the serpentine body formed by the connecting bone 5 to swing, thus creating a swinging effect and improving the user experience.

[0042] At this time, one end of the spiral shaft 3 is connected to the drive motor 1 through the reduction gear 2, so that the rotation of the spiral shaft 3 is controlled by the drive motor 1. During the rotation of the spiral shaft 3, the connecting bone 5 on the outer side of the spiral shaft 3 needs to swing. Therefore, in this embodiment, the spiral shaft 3 includes a spiral part 31 with a spiral line distributed in the middle position. The two ends of the spiral shaft 3 are respectively provided with a first rotating part 32 and a second rotating part 33. The axis of the first rotating part 32 is coaxial with the axis of the spiral part 31. The two ends of the spiral part 31 are respectively connected to the first rotating part 32 and the second rotating part 33 through an arc-shaped connecting part 34. At this time, the middle part of the spiral shaft 3 is located inside the connecting bone 5. The rotation angle between adjacent connecting bones 5 is controlled by the rotation of the spiral shaft 3. Therefore, the middle part of the spiral shaft 3 is a spiral part 31 with a spiral distribution. The spiral part 31 is spirally distributed. In this way, during the rotation of the spiral part 31, different positions of the spiral part 31 are at different angles and the whole is a smooth curve. As a result, the connecting bone 5 on the outside of the spiral part 31 is at different angle positions under the action of the spiral part 31. The angle of the connecting bone 5 also gradually changes from bottom to top, so that the outer side of the connecting bone 5 is smooth and will not cause discomfort during use.

[0043] The first rotating part 32 and the second rotating part 33 are connected to the two ends of the spiral part 31 by the connecting part 34 respectively. The first connecting seat 4 is located on the lower side and is connected to the reduction gear 2 through the first rotating part 32. At this time, the first rotating part 32 and the spiral part 31 are connected by the connecting part 34. The connecting part 34 is an inclined arc structure. The axis of the first rotating part 32 is designed to be coaxial with the axis of the spiral part 31. In this way, when the drive motor 1 controls the first rotating part 32 to rotate, each position of the spiral part 31 can be seen to rotate around the axis. Thus, the serpentine body formed by the connecting bone 5 will swing back and forth under the action of the spiral part 31.

[0044] In order to ensure the overall strength of the spiral shaft 3, in this embodiment, the spiral shaft 3 is a one-piece structure. Therefore, the spiral shaft 3 can be directly formed from a stainless steel rod with a certain strength, which reduces production costs and makes it less prone to breakage during use, thus ensuring the normal operation of the spiral shaft 3.

[0045] Of course, at this time, the reduction gear 2 consists of multiple meshing gears used for deceleration. The last one is the end gear, which is connected to the helical shaft 3, thereby transmitting the rotation to the position of the helical shaft 3. At this time, a rectangular part (the end gear has a corresponding rectangular groove) is also provided at the bottom of the helical shaft 3 to connect with the end gear. The rectangular part is engaged in the reduction gear 2, thereby realizing the power transmission of the reduction gear 2 to the position of the helical shaft 3.

[0046] To connect several connecting bones 5 sequentially and allow rotation between adjacent connecting bones 5, in this embodiment, the connecting bone 5 is generally elliptical. The upper connecting boss 53 and the lower connecting boss 54 are both located on the long side of the connecting bone 5. The arc-shaped groove 52 is located below the upper connecting boss 53. When the upper connecting boss 53 of an adjacent connecting bone 5 is engaged with the arc-shaped groove 52, the upper connecting boss 53 is located outside the lower connecting boss 54, and the connecting holes 55 are correspondingly provided. Because the connecting bone 5 is generally elliptical, when several connecting bones 5 are connected sequentially, the resulting serpentine body is an elliptical cylinder. Under the action of the spiral shaft 3, the connecting bones 5 have different angular positions, thus forming a swinging state of the elliptical cylinder at different angles.

[0047] In order to form a rotatable connection between adjacent connecting bones 5, in this embodiment, the adjacent connecting bones 5 are rotatably connected at the connection hole 55 by rivets. After the adjacent connecting bones 5 are rotatably connected at the connection hole position by rivets, the adjacent connecting bones 5 can rotate, thereby allowing the serpentine body formed by the connecting bones 5 to sway.

[0048] The connecting bone 5 at the lowest position is located outside the connecting part 34 between the first rotating part 32 and the spiral part 31. At this time, the connecting part 34 has an inclined arc structure. In order not to affect the normal swinging of the connecting bone 5 at the upper position, in this embodiment, the connecting bone 5 includes a lower connecting bone 510 near the first connecting seat 4. One to four lower connecting bones 510 are provided and are rotatably connected at the connecting hole 55. The width of the connecting groove 51 in the middle of the lower connecting bone 510 is 2 to 3 times the diameter of the spiral shaft 3. Specifically, in this embodiment, there are two lower connecting bones 510. The width of the connecting groove 51 in the middle of the lower connecting bone 510 is 2.5 times the diameter of the spiral shaft 3. At this time, the number of lower connecting bones 510 corresponds to the height of the connecting part 34. That is, the height of multiple lower connecting bones 510 when they are rotated together corresponds to the height of the connecting part 34. In this way, the connecting part 34 is basically located at the position of the connecting groove 51 of the lower connecting bone 510. The width of the connecting groove 51 at the position of the lower connecting bone 510 is relatively large, which can ensure that the inclined connecting part 34 can rotate normally, thereby ensuring the normal rotation of the spiral rod. Of course, at this time, although the connecting groove 51 at the position of the lower connecting bone 510 is relatively large, resulting in a smaller rotation angle of the corresponding lower connecting bone 510, it will not affect the swaying of the connecting bone 5 on the upper side of the lower connecting bone 510.

[0049] At this time, when the helical part 31 of the helical shaft 3 rotates, in order to allow the connecting bone 5 at the corresponding position on the outer side to be at different angles, in this embodiment, the connecting bone 5 also includes a swing connecting bone 520 on the upper side of the lower connecting bone 510. The width of the connecting groove 51 of the swing connecting bone 520 is 1.1-1.5 times the diameter of the helical shaft 3. Specifically, at this time, the width of the connecting groove 51 of the swing connecting bone 520 is 1.25 times the diameter of the helical shaft 3. At this time, the length direction of the connecting groove 51 is the side wall of the lower connecting boss 54, so the connecting groove 51 is rectangular in shape. Since the connecting bone 5 can only rotate around the axis position of the connecting hole, during the rotation of the helical shaft 3, the helical shaft 3 reciprocates within the connecting groove 51. At the same time, the helical shaft 3 causes the adjacent connecting bone 5 to rotate at the position of the connecting hole 55.

[0050] At this time, the upper side of the spiral shaft 3 is exposed. To avoid affecting the overall aesthetics and usability, in this embodiment, the uppermost side of the serpentine body is provided with a second connecting seat 6. The second connecting seat 6 is provided with a second rotating boss corresponding to the arc-shaped protrusion. The second rotating boss is provided with a second rotating hole. The middle part of the second connecting seat 6 is also provided with a second through hole through which the spiral shaft 3 passes. The end of the spiral shaft 3 passes through the second through hole to the upper side of the second connecting seat 6. The second connecting seat 6 is rotatably connected to the connecting bone 5 at the uppermost position through the second rotating boss, and the top of the spiral shaft 3 passes through the second through hole of the second connecting seat 6. Thus, the spiral shaft 3 passes through the second through hole to the upper side of the second connecting seat 6. At this time, the second rotating part 33 at the top of the spiral shaft 3 passes through the second through hole.

[0051] To enhance the user experience, in this embodiment, a swing seat 7 is provided on the upper side of the second connecting seat 6, and a swing sleeve 8 is fixed on the upper side of the swing seat 7. The swing seat 7 and the swing sleeve 8 form a receiving part, and a vibration motor is provided inside the receiving part. By placing the vibration motor inside the receiving part on the upper side of the second connecting seat 6, a vibration part is formed on the upper side of the serpentine body. This gives the entire serpentine swing motor a swinging and vibrating effect, bringing a different experience.

[0052] In this embodiment, to connect the vibratory motor to a power source, the receiving portion is provided with a wire hole communicating with the outside, and the power cord of the vibratory motor extends from the wire hole to the outside of the receiving portion. This facilitates the connection of the vibratory motor's power cord to a power source.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
