Description

Technical Field

For example, a motor directly connected to a rotating shaft can be used to enable a specific toy component to rotate or swing. However, this approach has limitations when achieving complex motion patterns, especially when multiple components need to move simultaneously in a coordinated manner. Traditional designs often require additional power units or complex linkage mechanisms to meet these requirements. This not only increases the cost of the toy, but also limits its structural flexibility and can easily cause positional interference with other components. Utility Model Content

[0038] Figure 1 and Figure 2 The multi-stage synchronous drive mechanism 10 in some embodiments of the present invention is shown. The multi-stage synchronous drive mechanism 10 can be applied to various toys in the prior art, and the shape, specifications or use of the toys are not limited.

[0039] like Figure 1As shown, the multi-stage synchronous drive mechanism 10 includes a housing 1 , a motor 2 , a gear transmission assembly 3 and a multi-stage actuator assembly 4 , and the motor 2 , the gear transmission assembly 3 and the multi-stage actuator assembly 4 are respectively arranged on the housing 1 .

[0040] As can be understood, housing 1 provides the necessary space and mounting locations for the remaining components and parts, while also providing some protection. Motor 2 generates torque when energized. Gear assembly 3 transmits the torque from motor 2 to multi-stage actuator 4. Multi-stage actuator 4 is able to move on housing 1 after receiving the torque.

[0041] like Figures 1 to 5 As shown, the motor 2 is mounted on the housing 1, and the gear transmission assembly 3 is drivingly connected to the motor 2. The multi-stage actuator assembly 4 includes a bracket 41, a sun gear 42, a plurality of planetary gears 43, and a plurality of actuator units 44. The bracket 41 is mounted on the housing 1, and the sun gear 42 and the planetary gears 43 are rotatably mounted on the bracket 41. The actuator units 44 are connected to the planetary gears 43 in a one-to-one correspondence. The sun gear 42 is drivingly connected to the gear transmission assembly 3, and the planetary gears 43 are meshed with the sun gear 42.

[0042] The motor 2 drives the sun gear 42 to rotate through the gear transmission assembly 3 , and the sun gear 42 drives the planetary gears 43 to rotate, thereby driving the execution units 44 to rotate relative to the housing 1 .

[0043] As will be appreciated, the gear transmission assembly 3 can be configured to transmit the output torque of the motor 2 to the sun gear 42 through the meshing of a series of gears. Bracket 41 provides mounting and support for the sun gear 42 and planetary gears 43, ensuring their smooth rotation. Bracket 41 is fixed to the housing 1, maintaining the stability of the entire multi-stage actuator assembly.

[0044] The sun gear 42 receives torque from the gear transmission assembly 3 and distributes the power to the planetary gears 43. Driven by the sun gear 42, the planetary gears 43 rotate about their own axes. The rotation of all planetary gears 43 is synchronized, thereby driving the synchronized movement of each actuator 44. The shape of the actuator 44 can be flexibly configured; however, it is important to avoid positional interference between the actuators 44 during rotation. Specifically, the shape and mounting angle of the actuators 44 can be adjusted to avoid positional interference during rotation.

[0045] It should be noted that when motor 2 is powered, it outputs a certain torque, which is transmitted to sun gear 42 via gear transmission assembly 3. Upon receiving the driving force, sun gear 42 begins to rotate. Because planetary gears 43 mesh with sun gear 42 and are mounted on bracket 41, each planetary gear 43 rotates about its own axis as sun gear 42 rotates. This rotation of each planetary gear 43 drives the connected actuator 44 to rotate relative to housing 1.

[0046] like Figures 3 to 5 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, each execution unit 44 includes a plug post 441, a limit plate 442 and a free arm 443 connected in sequence, the planetary gear 43 is sleeved on the plug post 441, the free arm 443 passes through the bracket 41, and the limit plate 442 is movably supported on the bracket 41.

[0047] As can be understood, the pin 441 is used to connect the planetary gear 43 and the stop plate 442. One end of the pin 441 is fixed to the planetary gear 43, and the other end is attached to the stop plate 442, ensuring that the rotation of the planetary gear 43 is transmitted to the stop plate 442 and the free arm 443. The stop plate 442 prevents the actuator 44 from falling out of the bracket 41. The free arm 443 is the end portion of the actuator 44 and is used to implement the specific movement function.

[0048] like Figure 3 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, the execution unit 44 also includes a limiting column 444, a limiting groove 431 is opened on the planetary gear 43, the limiting column 444 is arranged between the insert column 441 and the limiting plate 442, and the limiting groove 431 is adapted to the limiting column 444.

[0049] It is understandable that after the limiting post 444 is inserted into the limiting groove 431, it can fix the position of the planetary gear 43 and the execution unit 44. When the planetary gear rotates, the limiting post 444 and the limiting groove 431 cooperate to smoothly drive the execution unit to rotate.

[0050] like Figures 3 to 5 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10 , each free arm 443 has at least one torsion position 4431 .

[0051] It can be understood that the torsion position 4431 is a specific structure on the free arm 443 (specifically, it can be configured to be formed by twisting part of the free arm 443), which is used to form a torsion visual effect when the free arm 443 rotates, thereby increasing the diversity and complexity of the movement.

[0052] like Figure 3As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, each limiting groove 431 is provided with an alignment notch 432 at the same position; each limiting column 444 is provided with an alignment protrusion 4441, and the setting position and setting direction of each alignment protrusion 4441 on the limiting column are the same, and the alignment protrusion 4441 can be removably inserted into the alignment notch 432.

[0053] As can be understood, the alignment notches 432 are used to cooperate with the alignment protrusions 4441 on the limiting posts 444 to ensure that the limiting posts 444 are correctly positioned within the limiting grooves 431. The alignment protrusions 4441 are arranged in the same position and orientation on the limiting posts 444, ensuring that all limiting posts 444 have consistent alignment, which can guide the correct alignment during assembly.

[0054] Specifically, the installation direction of each execution unit can be directly determined by the orientation of each alignment protrusion 4441, thereby avoiding errors in assembly angles as much as possible.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, the sun gear 42 is provided with a plurality of alignment marks 421 in the circumferential direction, the alignment marks 421 are distributed at equal intervals, and the alignment marks 421 correspond one-to-one to the alignment protrusions 4441.

[0056] It can be understood that the alignment mark 421 is a specific structure in the circumferential direction of the sun gear 42, which is used to cooperate with the alignment protrusion 4441 on the limiting column 444 to ensure the precise alignment of the initial position and rotation angle of the planetary gear 43 and the execution unit 44, thereby effectively preventing the positional interference of each execution unit 44 during the rotation process.

[0057] like Figures 2 to 5 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, the bracket 41 includes a base 411 and an upper cover 412. The base 411 is provided with a mounting hole 4111 and a plurality of through holes 4112. The upper cover 412 is provided with a connecting hole 4121 and a plurality of avoidance holes 4122.

[0058] The base 411 is connected to the upper cover 412, and an accommodating space 413 is set between the base 411 and the upper cover 412. The sun gear 42 and each planetary gear 43 are located in the accommodating space 413. The sun gear 42 is set in the mounting hole 4111, and each free arm 443 is passed through each through hole 4112 in a one-to-one manner. Each plug post 441 is inserted into each avoidance hole 4122 in a one-to-one manner. At least part of the sun gear 42 is exposed in the connecting hole 4121 for connection with the gear transmission assembly 3.

[0059] As will be understood, base 411 is used to secure and support sun gear 42 and planetary gears 43. Mounting hole 4111 is used to mount sun gear 42, ensuring that sun gear 42 is secured and positioned on base 411. Through hole 4112 is used to pass free arm 443 through, ensuring that free arm 443 can extend from base 411 to achieve the desired movement.

[0060] The upper cover 412 and the base 411 cooperate to form a housing 413, which protects the internal components. The connecting hole 4121 is used to connect the gear transmission assembly 3, ensuring that the gear transmission assembly 3 can transmit power to the sun gear 42. The clearance hole 4122 is used to insert the plug 441. The hole wall of the clearance hole 4122 is used to define the position of the plug 441, ensuring smooth rotation of the plug 441.

[0061] like Figures 3 to 5 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, the gear transmission assembly 3 includes a torque gear 31, a torque transmission column 311 is provided on the torque gear 31, and the torque gear 31 is drivingly connected to the motor 2;

[0062] The sun gear 42 is provided with a center column 422 , and a torque slot 4221 is formed at the end of the center column 422 ;

[0063] The center column 422 is provided with a connecting hole 4121 , and the torque transmission column 311 is detachably inserted into the torque slot 4221 . When the torque gear 31 is driven by the motor 2 to rotate, the torque transmission column 311 drives the center column 422 to rotate, thereby rotating the sun gear 42 .

[0064] It can be understood that the torque gear 31 is used to transmit the torque output by the motor 2 to the sun gear 42. Specifically, the torque gear 31 transmits the rotational power of the motor 2 to the sun gear 42 through a driving connection with the motor 2.

[0065] The torque transmission column 311 is used to cooperate with the center column 422 on the sun gear 42 to achieve torque transmission. When the torque gear 31 is driven by the motor 2 to rotate, the torque transmission column 311 will drive the center column 422 to rotate, thereby driving the sun gear 42 to rotate.

[0066] The torque transmission column 311 is detachably inserted into the torque slot 4221, which facilitates installation and maintenance, and also allows adjustment or replacement of components when necessary.

[0067] The torque slot 4221 is used to cooperate with the torque transmission column 311 to achieve torque transmission.

[0068] like Figures 1 to 5 As shown, in some embodiments of the multi-stage synchronous drive mechanism 10, the multi-stage synchronous drive mechanism 10 further includes a mounting frame 5, and the motor 2 is disposed on the mounting frame 5;

[0069] The gear transmission assembly 3 further includes a worm 32 and a plurality of transmission gears 33. Each transmission gear 33 is rotatably mounted on the mounting frame 5. The motor 2 is driven and connected to the worm 32. Each transmission gear 33 is meshed in sequence. One of the transmission gears 33 is meshed with the worm 32.

[0070] When the mounting bracket 5 and the support 41 are aligned and assembled, the mounting bracket 5 drives the other transmission gear 33 to engage with the torque gear 31 .

[0071] As will be understood, the mounting bracket 5 is used to secure the motor 2 and some components of the gear transmission assembly 3. It provides a mounting and securing location for the motor 2 and worm 32, ensuring their stability and reliability during operation. The worm 32 is used to transmit the torque of the motor 2 to the transmission gears 33. The transmission gears 33 mesh sequentially, transferring power from the worm 32 to the torque gear 31.

[0072] like Figure 1 As shown, the electric toy 20 includes a multi-stage synchronous driving mechanism 10 and a plurality of light-emitting components 30 . Each light-emitting component 30 is located in the housing 1 and is correspondingly inserted into the bracket 41 .

[0073] It is understandable that the light emitting element 30 is used to provide a visual effect and enhance the interactivity and fun of the toy. The light emitting element 30 can emit light of different colors and brightness to increase the visual appeal of the toy and make the toy attract the user's attention even in a dark environment.

[0074] The light-emitting element 30 can synchronize with the movement of the multi-stage synchronous drive mechanism 10, for example, lighting up or flashing during certain movements, increasing the interactivity and fun of the toy. The light-emitting element 30 can be installed in different parts of the toy, and through different arrangements and combinations, unique visual effects can be created to enhance the toy's aesthetics.

[0075] The implementation of this utility model has the following beneficial effects:

[0076] The utility model relates to a multi-stage synchronous drive mechanism and an electric toy. The electric toy includes the multi-stage synchronous drive mechanism. In the multi-stage synchronous drive mechanism, the meshing action between the sun gear and the planetary gears ensures that all actuators rotate synchronously according to a preset ratio, thereby greatly improving the consistency and accuracy of the movement of each actuator.

[0077] Furthermore, the motor's torque is transmitted to the sun gear via the gear transmission assembly, and a single sun gear can simultaneously drive the rotation of multiple planetary gears, thereby driving the rotation of multiple actuators relative to the bracket, without the need for multiple transmission structures or multiple transmission shafts. This allows the present invention to achieve both excellent structural flexibility and low manufacturing costs.
