The terminology used in this specification of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present invention.

[0026] Please refer to the following at the same time Figure 1-8 This embodiment provides a power mechanism for a dancing toy, including a housing 1 and a motor 2 and a gear assembly 3 respectively fixedly installed in the housing 1. The gear assembly 3 is driven to rotate by the motor 2 and is used to connect with other components of the dancing toy to realize the dancing action of the dancing toy.

[0027] The housing 1 includes a detachably fixed first housing 11 and a second housing 12. In this embodiment, the first housing 11 and the second housing 12 are detachably fixed using a snap-fit ​​structure. In other embodiments, the first housing 11 and the second housing 12 can be detachably connected using other structures, such as threaded fixing structures, slot insertion structures, etc. It is understood that the housing 1 has a first chamber 110 for fixing and installing the motor 2 and a second chamber 120 for fixing and installing the gear assembly 3. The second chamber 120 has a through hole 121 for the eccentric pins of the first output gear, the second output gear, and the third output gear in the gear assembly 3 to pass through.

[0028] The gear assembly 3 includes an input gear 31, a transmission gear 32, a first gear set 33, a second gear set 34, a first output gear 35, a second output gear 36, and a third output gear 37. Compared with existing structures, the gear assembly 3 provided in this embodiment has a relatively smaller number of gears, which helps to simplify the structure, save space, and make the overall structure of the power mechanism simpler, more compact, and smaller. It is understood that both the input gear 31 and the transmission gear 32 have inclined tooth surfaces, and the teeth on the two tooth surfaces are meshed together. The first gear set 33 includes a first double gear 33a and a second double gear 33b that are coaxially rotatably connected, wherein the first double gear 33a meshes with the transmission gear 32. The second gear assembly 34 includes a driving gear 34a and a follower gear 34b coaxially movably connected. Both the driving gear 34a and the follower gear 34b are meshed with the first double gear 33a, and their rotational speeds are different. Under the drive of the driving gear 34a and an elastic element (not shown), the follower gear 34b can intermittently mesh with the first output gear 35, the second output gear 36, and the second double gear 33b. The second output gear 36 and the third output gear 37 are both meshed with the second double gear 33b. Through this arrangement, the gear assembly 3, while continuously rotating under the control of the motor 2, can cyclically control the rotation of the first output gear 35, the forward rotation of the second output gear 36 and the third output gear 37, and the reverse rotation of the second output gear 36 and the third output gear 37, enabling the gear assembly 3 to drive the dancing toy to intermittently perform various dancing movements.

[0029] The input gear 31 is fixed to the output shaft of the motor 2. The input gear 31 is integrally formed from a cylinder and a frustum with decreasing diameter. Multiple spaced first tooth grooves 311 extend obliquely from the middle of the side of the cylinder towards the end of the frustum, forming the tooth surface of the input gear 31. The transmission gear 32 includes a first tooth 32a and a second tooth 32b coaxially fixed. The first tooth 32a is integrally formed from a cylinder and a frustum with decreasing diameter. Multiple spaced second tooth grooves 321 extend obliquely from the middle of the side of the cylinder towards the end of the frustum, forming the tooth surface of the first tooth 32a. It can be understood that the first tooth 32a meshes with the input gear 31, and the second tooth 32b is a spur gear and meshes with the first double gear 33a. Compared with the spur gear structure used in the prior art, this embodiment connects the input gear 31 and the transmission gear 32 by meshing through teeth distributed on the inclined tooth surface. The force on the above meshing structure is a gradual process, which can avoid sudden engagement and disengagement, thereby reducing impact and vibration, making the transmission smoother, helping to reduce the vibration and noise of the power mechanism, and improving the user experience.

[0030] The first double gear 33a includes a third tooth 331 meshing with the second tooth 32b and a fourth tooth 332 meshing with the second gear set 34. In this embodiment, the third tooth 331 is provided with a gear ring 3311, and the fourth tooth 332 is provided with an elastic gear ring 3321. The elastic gear ring 3321 is engaged and disengaged within the gear ring 3311 by a convex tooth 3322, so that when the fourth tooth 332 is restricted and cannot rotate, the third tooth 331 can still rotate under the driving force of the motor 2, which can prevent the motor 2 from jamming and burning out. In other embodiments, the third tooth 331 and the fourth tooth 332 can be integrally formed. Similarly, the structure of the gear ring 3311 and the elastic gear ring 3321 can be provided on the transmission gear 32. Returning to this embodiment, the second double gear 33b includes a fifth tooth 333 and a sixth tooth 334 fixed coaxially, wherein the fifth tooth 333 is meshed with the second output gear 36 and the third output gear 37 respectively, and the sixth tooth 334 is detachably meshed with the follower gear 34b.

[0031] The driving gear 34a has a first connecting groove 341 on the outer periphery of its shaft. A push rod 3411 protrudes outward from the inner wall of the first connecting groove 341. The push rod 3411 is in contact with the follower gear 34b and is used to push the follower gear 34b to move at different distances during rotation, so that the follower gear 34b can intermittently mesh with the first output gear 35, the second output gear 36, and the sixth tooth 334. The follower gear 34b includes a seventh tooth 343, an eighth tooth 344, and a ninth tooth 345 that are coaxially fixed. The seventh tooth 343 meshes with the fourth tooth 332 and its number of teeth is less than or greater than the number of teeth of the driving gear 34a, so that the seventh tooth 343 and the driving gear 34a can rotate at different speeds under the rotation of the fourth tooth 332. One side of the seventh tooth 343 has a second connecting groove 3431 on its outer periphery of the axis. A stepped plate 3432 protrudes outward from the inner wall of the second connecting groove 3431. The stepped plate 3432 has two plates of different heights, and both plates have ramps along the rotation direction to guide the movement of the push rod 3411. It can be understood that the stepped plate 3432 can intermittently contact and connect with the push rod 3411 during rotation, and when the stepped plate 3432 separates from the push rod 3411, it can extend into the first connecting groove 341. In this embodiment, the other side of the seventh tooth 343 also has a slot 3433; correspondingly, the eighth tooth 344 and the ninth tooth 345 are integrally formed. The ninth tooth 345 has a protruding polygonal prism-shaped insert 3451, which is pluggably and fixedly connected to the slot 3433, allowing the eighth tooth 344 and the ninth tooth 345 to rotate simultaneously and in the same direction as the seventh tooth 343. This arrangement also helps to simplify the production process of the tunnel gear 34b and save production costs. It can be understood that the eighth tooth 344 is elastically connected to the second chamber 120 via the elastic element, which is used to push the follower gear 34b towards the driving gear 34a, allowing the push rod 3411 to abut against the connecting step plate 3432 and extend into the second connecting groove 3431. During movement, the eighth tooth 344 can intermittently mesh with the second output gear 36 and the sixth tooth 334, and the ninth tooth 345 can intermittently mesh with the first output gear 35. In other embodiments, the seventh tooth 343, the eighth tooth 344, and the ninth tooth 345 can be integrally formed.

[0032] The first output gear 35 and the third output gear 37 are both single gears with an eccentric column 380, while the second output gear 36 is a double gear with an eccentric column 380. It can be understood that the second output gear 36 includes a tenth tooth 361 and an eleventh tooth 362 fixed coaxially. The tenth tooth 361 has the same number of teeth as the third output gear 37 and is meshed with the fifth tooth 333. The eleventh tooth 362 is detachably meshed with the eighth tooth 344.

[0033] Understandable. Figure 6-8 The diagram illustrates the process by which the second gear set 34 intermittently meshes with the first output gear 35, the second output gear 36, and the second double gear 33b during rotation to control its rotation. As shown in Figure 6, when the driving gear 34a rotates relative to the seventh tooth 343 to the position where the push rod 3411 is misaligned with the step plate 3432, the push rod 3411 extends into the second connecting groove 3431, and the follower gear 34b moves under the energy release of the elastic element, causing the ninth tooth 345 to mesh with the first output gear 35, thereby driving the first output gear 35 to rotate. As shown in Figure 7, when the driving gear 34a rotates relative to the seventh tooth 343 until the push rod 3411 abuts against the lower step of the stepped plate 3432, the push rod 3411 pushes the follower gear 34b to move and compress the elastic element, causing the eighth tooth 344 to mesh with the eleventh tooth 362, thereby driving the second output gear 36 to rotate. At the same time, the second output gear 36 drives the third output gear 37 to rotate in the same direction as the second output gear 36 through the second double gear 33b. As shown in Figure 8, when the driving gear 34a rotates relative to the seventh tooth 343 until the push rod 3411 abuts against the higher step of the stepped plate 3432, the push rod 3411 pushes the follower gear 34b to move and further compress the elastic element, causing the eighth tooth 345 to mesh with the sixth tooth 334, thereby driving the second double gear 33b to simultaneously drive the second output gear 36 and the third output gear 37 to rotate in opposite directions.

[0034] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
