(11) FIG. 1 and FIG. 2 show a multi-stage synchronous driving mechanism 10 in some embodiments of the present disclosure. The multi-stage synchronous driving mechanism 10 can be applied to various toys in the prior art, and shapes, specifications, or uses of the toys are not limited.

(12) As shown in FIG. 1, the multi-stage synchronous driving mechanism 10 includes a housing 1, a motor 2, a gear transmission component 3, and a multi-stage execution component 4. The motor 2, the gear transmission component 3, and the multi-stage execution component 4 are disposed on the housing 1, respectively.

(13) It may be understood that the housing 1 is configured to provide space required for installation of remaining components and parts and an installation position, and further plays a protective role. The motor 2 is configured to output torque when being powered on. The gear transmission component 3 is configured to further transfer the torque output by the motor 2 to the multi-stage execution component 4. The multi-stage execution component 4 can move on the housing 1 after receiving the torque.

(14) As shown in FIG. 1 to FIG. 5, the motor 2 is disposed on the housing 1, and the gear transmission component 3 is driven and connected to the motor 2. The multi-stage execution component 4 includes a support 41, a sun gear 42, a plurality of planetary gears 43, and a plurality of execution units 44. The support 41 is disposed on the housing 1. The sun gear 42 and each of the planetary gears 43 are rotatably disposed on the support 41, respectively. Each of the execution units 44 is connected to each of the planetary gears 43 in a one-to-one correspondence. The sun gear 42 is driven and connected to the gear transmission component 3. Each of the planetary gears 43 is engaged with the sun gear 42, respectively.

(15) The motor 2 drives the sun gear 42 to rotate by using the gear transmission component 3, so that the sun gear 42 drives each of the planet gears 43 to rotate, thereby driving each of the execution units 44 to rotate relative to the housing 1.

(16) It may be understood that the gear transmission component 3 may be configured to transfer output torque of the motor 2 to the sun gear 42 by means of engagement of a series of gears. The support 41 provides installation and support for the sun gear 42 and the planetary gear 43 to ensure that the sun gear 42 and the planetary gear 43 can rotate smoothly. The support 41 is fastened to the housing 1 to maintain stability of the entire multi-stage execution component.

(17) The sun gear 42 receives the torque from the gear transmission component 3 and distributes power to each planetary gear 43. The planetary gear 43 is driven by the sun gear 42, and the planetary gear 43 rotates around an axis of the planetary gear 43. Rotation of all the planetary gears 43 is synchronized, so that the execution units 44 move synchronously. An appearance of the execution unit 44 may be flexibly set. However, mutual interference in a position of each execution unit 44 during rotation should be avoided. Specifically, an appearance of the execution unit 44 and an installation angle may be adjusted to avoid position interference during rotation.

(18) It should be noted that, after the motor 2 is powered on, the motor 2 outputs specific torque, and transfers the torque to the sun gear 42 by using the gear transmission component 3. The sun gear 42 starts to rotate after being subjected to a driving force. Because the planetary gear 43 keeps in engagement with the sun gear 42 and the planetary gear 43 is installed on the support 41, each planetary gear 43 rotates around own axis along with rotation of the sun gear 42. Rotation of each planetary gear 43 may drive the execution unit 44 connected to the planetary gear 43 to rotate relative to the housing 1.

(19) As shown in FIG. 3 to FIG. 5, in some embodiments of the multi-stage synchronous driving mechanism 10, each of the execution units 44 includes an insertion post 441, a stop plate 442, and a free arm 443 that are connected in sequence. The planetary gear 43 is sleeved on the insertion post 441. The free arm 443 is penetrated in the support. The stop plate 442 movably abuts against the support 41.

One end of the insertion post 441 is fixed on the planetary gear 43, and the other end of the insertion post 441 is disposed on the stop plate 442, thereby ensuring that rotation of the planetary gear 43 can be transferred to the stop plate 442 and the free arm 443. The stop plate 442 plays a role in preventing the execution unit 44 from releasing the support 41. The free arm 443 is a tail end part of the execution unit 44, and is configured to implement a specific motion function.

(21) As shown in FIG. 3, in some embodiments of the multi-stage synchronous driving mechanism 10, the execution unit 44 further includes a stop post 444. A stop slot 431 is disposed on the planetary gear 43. The stop post 444 is disposed between the insertion post 441 and the stop plate 442. The stop slot 431 is adapted to the stop post 444.

(22) It may be understood that, after the stop post 444 is inserted into the stop slot 431, positions of the planetary gear 43 and the execution unit 44 can be fixed. When the planetary gear rotates, the execution unit is smoothly driven to rotate by cooperating with the stop post 444 and the stop slot 431.

At least a part of the sun gear 42 is exposed in the connecting hole 4121 for connection with the gear transmission component 3.

(32) It may be understood that the base 411 is configured to fix and support the sun gear 42 and the planetary gear 43. The installation hole 4111 is configured to install the sun gear 42 to ensure that the sun gear 42 is fixed and positioned on the base 411. The through hole 4112 is configured to penetrate through the free arm 443 to ensure that the free arm 443 can stretch out from the base 411 for predetermined motion.

(33) The upper cover 412 cooperates with the base 411 to form an accommodation interval 413 for protecting internal components. The connecting hole 4121 is configured to connect the gear transmission component 3 to ensure that the gear transmission component 3 can transfer power to the sun gear 42. The avoidance hole 4122 is configured to insert the insertion post 441, so as to perform position limitation on the insertion post 441 by using a hole wall of the avoidance hole 4122, thereby ensuring smooth rotation of the insertion post 441.
