[0045] Figure 1 and Figure 2 An electric toy 20 in some embodiments of the present invention is shown. The electric toy 20 is provided with a transmission device 10. When the transmission device 10 is in operation, it can output kinetic energy in different directions.

[0046] like Figures 1 to 3As shown, the transmission device 10 includes a base 1 , a driving mechanism 2 , a two-way clutch transmission mechanism 3 and an actuator 4 , and the driving mechanism 2 , the two-way clutch transmission mechanism 3 and the actuator 4 are disposed on the base 1 .

[0047] As can be understood, the base 1 serves as a load-bearing mechanism. The drive mechanism 2 is used to output torque during operation. The bidirectional clutch transmission mechanism 3 is used to transmit torque in two different directions. The actuator 4 is used to receive torque and perform different actions.

[0048] like Figures 4 to 7 As shown, the driving mechanism 2 includes a motor 21 and a worm 22 . The motor 21 is disposed on the base 1 , and the worm 22 is driven by the motor 21 .

[0049] like Figures 3 to 7 As shown, the two-way clutch transmission mechanism 3 includes a transmission gear 31, a first clutch gear 32, a second clutch gear 33, a first transmission shaft 34, an eccentric wheel 35, a drive gear 36, a drive shaft 37 and a drive crown gear 38. The transmission gear 31, the first clutch gear 32 and the second clutch gear 33 are respectively rotatably arranged on the base body 1. The transmission gear 31 is engaged with the worm 22. The first clutch gear 32 and the second clutch gear 33 are respectively engaged with the transmission gear 31. The first transmission shaft 34 passes through the first clutch gear 32. The eccentric wheel 35 is arranged at the end of the first transmission shaft 34. The drive gear 36 is engaged with the first clutch gear 32. The drive shaft 37 passes through the drive gear 36. The drive crown gear 38 is engaged with the second clutch gear 33.

[0050] like Figures 2 to 7 As shown, the actuator 4 includes an actuator plate 41 , a moving wheel 42 and a planetary assembly 43 . A sliding groove 411 is provided on the actuator plate 41 . The moving wheel 42 is disposed on the driving shaft 37 . The driving crown gear 38 is drivingly connected to the planetary assembly 43 .

[0051] It is understood that the motor 21 is used to rotate the driving worm 22, and the worm 22 drives the transmission gear 31 meshed with it to rotate during the rotation. The transmission gear 31 is used to drive the first clutch gear 32 and the second clutch gear 33 to rotate when rotating.

[0052] When the first clutch gear 32 rotates, it can drive the first transmission shaft 34 to rotate, and the first transmission shaft 34 drives the eccentric wheel 35 to rotate. When the eccentric wheel 35 rotates, it can correspondingly drive the actuator plate 41 to slide relative to the base body 1 (this is the torque output in the first direction).

[0053] The rotation of the first clutch gear 32 will also drive the driving gear 36 meshing with it to rotate, and the driving gear 36 will drive the driving shaft 37 to rotate, and the driving shaft 37 will drive the moving wheel 42 to rotate (this is the torque output in the second direction).

[0054] When the second clutch gear 33 rotates, it drives the driving crown gear 38 meshing with it to rotate. When the driving crown gear 38 rotates, it inputs torque to the planetary assembly 43 (this is the torque output in the third direction).

[0055] It should be noted that the actuator plate 41 moves by sliding after receiving torque. The direction of rotation of the driving wheel 42 is different from that of the driving crown gear 38. This allows motion feedback in three different directions, effectively enhancing the product's motion feedback. This increases the product's motion diversity while maintaining its overall compactness.

[0056] like Figure 5 and Figure 6 As shown, in some embodiments of the transmission device 10, the first clutch gear 32 includes a first driving gear 321, a first driven gear 322, and a first clutch spring 323. The first driving gear 321, the first driven gear 322, and the first clutch spring 323 are respectively mounted on the first transmission shaft 34. The first clutch spring 323 is used to provide a force that drives the first driven gear to slide toward the first driving gear 321, so that the first driven gear 322 can be detachably inserted into the first driving gear 321. The first driven gear 322 is fixedly connected to the first transmission shaft 34, and the first driving gear 321 is respectively engaged with the transmission gear 31 and the driving gear 36.

[0057] As can be understood, the first driving gear 321 is used to directly receive the power from the transmission gear 31 and transmit the torque directly to the drive gear 36. The first driven gear 322 is detachably connected to the first driving gear 321. The first clutch spring 323 can always provide a force that drives the first driven gear 322 to slide closer to the first driving gear 321.

[0058] It should be noted that when the movement of the actuator plate 41 is blocked, the eccentric wheel 35 will also be unable to rotate. Subsequently, as the motor 21 continues to output torque, the first driving gear 321 will continue to rotate, while the first driven gear 322, which is already movably connected to the first driving gear 321, will not rotate with it. In other words, when the eccentric wheel 35 is unable to rotate, torque can still be transmitted to the driven wheel 42 through the first driving gear 321.

[0059] like Figure 5 and Figure 6As shown, in some embodiments of the transmission device 10, the second clutch gear 33 includes a second driving gear 331 and a second driven gear 332. The second driving gear 331 has a mating slot 3311, and the second driven gear 332 has a spring-loaded engagement portion 3321. The spring-loaded engagement portion 3321 is removably inserted into the wall of the mating slot 3311. The second driving gear 331 is meshed with the transmission gear 31, and the second driven gear 332 is meshed with the driving crown gear 38.

[0060] As will be understood, when the transmission device 10 is operating normally, the motor 21 drives the transmission gear 31 to rotate via the worm 22. This rotation of the transmission gear 31 also drives the meshing second driving gear 331 to rotate. Because the second driven gear 332 is in close contact with the mating groove 3311 of the second driving gear 331 via the elastic engagement portion 3321, the rotation of the second driving gear 331 directly drives the second driven gear 332. The second driven gear 332 then transmits power to the driving crown gear 38, ultimately driving the planetary assembly 43 to complete its intended operation.

[0061] It should be noted that in certain situations, if the planetary assembly 43 or its associated parts encounter abnormal resistance, resulting in an inability to rotate normally, this could pose a potential threat to the entire transmission system. In these situations, the design of the second clutch gear 33 plays an important role. When the second driven gear 332 encounters excessive resistance, the friction between the elastic engagement portion 3321 and the engagement groove 3311 is insufficient to overcome this resistance, causing slippage between the second driven gear 332 and the second driving gear 331. This means that even if the second driving gear 331 continues to rotate, the second driven gear 332 will not rotate with it, thereby preventing equipment damage caused by excessive load.

[0062] like Figure 5 and Figure 6 As shown, in some embodiments of the transmission device 10, the second clutch gear 33 further includes a second transmission shaft 333, and the second transmission shaft is disposed on the base body 1;

[0063] The second driving gear 331 and the second driven gear 332 are respectively sleeved on the second transmission shaft 333. The second driven gear 332 is provided with a clutch elastic member 3322. The clutch elastic member 3322 is located in the matching groove 3311. The clutch elastic member 3322 is provided with at least one elastic matching portion 3321. The groove wall of the matching groove 3311 is provided with a plurality of limiting grooves 3312.

[0064] When the second driving gear 331 and the second driven gear 332 rotate relative to each other, the elastic fitting portion 3321 is driven by the clutch elastic member 3322 to slide along the groove wall of the fitting groove 3311 , so that the elastic fitting portion 3321 can be detached and fall into the limiting groove 3312 .

[0065] It can be understood that the second transmission shaft 333 serves as a common support point for the second driving gear 331 and the second driven gear 332. The second transmission shaft 333 not only provides a stable rotation center for the two gears, but also helps reduce friction loss during rotation and improve transmission efficiency.

[0066] Each limiting groove 3312 is used to interact with the elastic matching portion 3321 on the second driven gear 332 to achieve power transmission and disconnection.

[0067] At least one elastic engagement portion 3321 is disposed within or outside the clutch spring 3322. When the second driving gear 331 and the second driven gear 332 rotate relative to each other, the elastic engagement portion 3321, under the action of the clutch spring 3322, slides along the wall of the engagement slot 3311 and can fall into the corresponding retaining slot 3312. If the rotational resistance is too great, the elastic engagement portions 3321 will fall into the retaining slot 3312 one by one and then escape.

[0068] like Figure 5 and Figure 6 As shown, in some embodiments of the transmission device 10 , the transmission gear 31 includes a first transmission spur gear 311 and a second transmission spur gear 312 that are coaxially arranged, and the first transmission spur gear 311 and the second transmission spur gear 312 are fixedly connected.

[0069] As will be understood, the first transmission spur gear 311 meshes with the worm 22 and is used to receive power from the worm 22. The first transmission spur gear 311, through its tooth profile, meshes with the helical teeth of the worm 22, converting the rotational motion of the worm 22 into its own rotational motion. The second transmission spur gear 312 is coaxially fixedly connected to the first transmission spur gear 311, and the two rotate synchronously as a unit. The second transmission spur gear 312 meshes with the first clutch gear 32 and the second clutch gear 33, respectively, transmitting power to these two clutch gears.

[0070] like Figures 1 to 4 as well as Figure 7 As shown, the electric toy 20 includes a housing 30 and a transmission device 10. The base 1 is assembled within the housing 30, the actuator 41 is slidably disposed within the housing 30, the moving wheel 42 is exposed outside the housing 30, and the planetary assembly 43 is disposed within the housing 30. A first transmission shaft 34, an eccentric wheel 35, a driving gear 36, and a driving shaft 37 are all located on the base 1, and a driving crown gear 38 is rotatably disposed within the housing 30.

[0071] As will be understood, the housing 30 houses and protects the transmission device 10 and other electronic components. The base 1 is secured within the housing 30, supporting and securing the other components. The actuator 41 can be slidably connected to the housing 30 via a grooved rail structure, a guide rail structure, or other conventional linear guide structures.

[0072] It should be noted that when the actuator plate 41 slides, it can cause components mounted on the actuator plate 41 to rotate or slide. Of course, the actuator plate 41 can also be configured to cause components fixed to the actuator plate 41 to slide, thereby causing corresponding movements on the housing. When the moving wheel 42 rotates, it can cause the housing 30 to move, thereby providing the electric toy 20 with a mobile function.

[0073] like Figures 4 to 7 As shown, in some embodiments, the execution plate 41 is provided with at least one first guide track 412 and at least one second guide track 413;

[0074] The electric toy 20 further includes a movable device 5, which includes at least one first movable member 51 and at least one second movable member 52. The first movable member 51 is provided with a first rotating shaft 511 and a first guide portion 512, and the second movable member 52 is provided with a second rotating shaft 521 and a second guide portion 522.

[0075] The first rotating shaft and the second rotating shaft are respectively rotatably disposed on the housing 30 , the first guide portion 512 is slidably disposed on the first guide track 412 , and the second guide portion 522 is slidably disposed on the second guide track 413 ;

[0076] When the eccentric wheel 35 rotates, the actuator plate 41 is pushed and slid back and forth on the housing 30 , so that the first guide portion 512 moves along the first guide track 412 , and the second guide portion 522 moves along the second guide track 413 , and then the first movable member 51 and the second movable member 52 rotate on the housing 30 respectively.

[0077] It can be understood that the first guide track 412 is used to guide the movement of the first movable member 51 , and the second guide track 413 is used to guide the movement of the second movable member 52 .

[0078] When the motor 21 is started, the worm 22 drives the transmission gear 31 to rotate, which in turn drives the first clutch gear 32 and the first transmission shaft 34 to rotate. The rotation of the first transmission shaft 34 rotates the eccentric wheel 35. The rotation of the eccentric wheel 35 forces the actuator plate 41 to slide back and forth within the housing 30.

[0079] The reciprocating sliding of the actuator plate 41 causes the first guide portion 512 to move along the first guide track 412. The movement of the first guide portion 512 drives the first movable member 51 to rotate about the first rotation axis 511. Similarly, the reciprocating sliding of the actuator plate 41 causes the second guide portion 522 to move along the second guide track 413. The movement of the second guide portion 522 drives the second movable member 52 to rotate about the second rotation axis 521.

[0080] By designing different guide tracks on the execution plate 41 , various motion modes of the first movable member 51 and the second movable member 52 can be realized, thereby enriching the dynamic effects of the electric toy 20 .

[0081] Specifically, in some embodiments, the length extension direction of the first rotation axis intersects the length extension direction of the second rotation axis at an acute angle or an obtuse angle.

[0082] As can be understood, the lengthwise extension of the first rotating shaft intersects the lengthwise extension of the second rotating shaft at an acute or obtuse angle. This non-parallel arrangement further diversifies the movement directions of the first movable member 51 and the second movable member 52, enhancing the dynamic effect of the toy. Specifically, the rotational direction of the first movable member 51 is different from the rotational direction of the second movable member 52.

[0083] like Figures 5 to 7 As shown, in some embodiments, the planetary assembly 43 includes a frame 431 , a sun gear 432 , a plurality of free arms 433 , and a plurality of planetary gears 434 ;

[0084] The frame 431 is mounted on the housing 30 . The sun gear 432 and the free arms 433 are rotatably mounted on the frame 431 . The driving crown gear 38 is drivingly connected to the sun gear 432 . The planetary gears 434 are correspondingly mounted on the free arms 433 . The planetary gears 434 are meshed with the sun gear 432 .

[0085] When the motor 21 drives the crown gear 38 to rotate the sun gear 432 , the sun gear 432 drives the planetary gears 434 to rotate, and the planetary gears 434 drive the free arms 433 to rotate relative to the housing 30 .

[0086] As can be understood, the frame 431 serves as the supporting structure for the planetary assembly 43. The sun gear 432 is used to drive the planetary gears 434 during rotation. Each free arm 433 is rotatably mounted on the frame 431, and each free arm 433 is provided with a planetary gear 434. The planetary gears 434 are mounted on each free arm 433 in a one-to-one correspondence and mesh with the sun gear 432.

[0087] It should be noted that the motor 21 drives the drive crown gear 38 via the worm 22 and transmission gear 31. The drive crown gear 38, through the engagement of the torque pin with the torque slot on the sun gear 432, drives the sun gear 432 to rotate. The rotation of the sun gear 432 drives the meshing planetary gears 434. The rotation of the planetary gears 434, in turn, drives the free arms 433 to rotate relative to the housing 30. In this way, the complex motion of multiple free arms 433 can be achieved under the drive of a single motor 21, further enriching the dynamic effects of the electric toy 20.

[0088] like Figure 6 As shown, in some embodiments, a torque slot 4321 is provided on the sun gear 432 , and a torque plug is provided on the driving crown gear 38 , and the torque plug is detachably inserted into the torque slot 4321 .

[0089] It can be understood that the torque plug on the driving crown gear 38 is inserted into the torque slot 4321 on the sun gear 432, so that when the driving crown gear 38 rotates, the sun gear 432 can be driven to rotate.

[0090] The implementation of this utility model has the following beneficial effects:

[0091] The utility model relates to a transmission device and an electric toy. The transmission device is provided on an electric toy. The transmission device combines a motor, a worm gear, a transmission gear, a two-way clutch transmission mechanism, and an actuator to drive an actuator plate, a moving wheel, and a planetary assembly with different motion functions on a base, achieving efficient power transmission within a limited space. This compact design reduces the complexity of the internal structure, making the electric toy smaller and more compact, and improving the product's portability and aesthetics.

[0092] At the same time, the power output by the motor needs to pass through the first clutch gear and the second clutch gear before it can be further transmitted to the actuator. This can protect the components and structures used for power transmission, improve the durability of the product, and extend the service life of the product.

[0093] In addition, the present invention can achieve three-directional power output through a limited number of components in the two-way clutch transmission mechanism, greatly reducing the number of mechanical components and reducing structural complexity, making maintenance and overhaul easier.

[0094] The scheme of the present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have their own emphases. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
