Description

Technical Field

[0001] This application relates to the technical field, specifically to a doll with a skirt that can move up and down. Background Technology

[0002] With the continuous upgrading of the domestic toy consumption market and the diversified development of children's entertainment needs, electric interactive toys, with their dynamic and immersive experience advantages, have become one of the core categories with the highest market share in the toy market. In recent years, the technological iteration of electric toys has been accelerating. Existing electric doll products can integrate multiple functions such as autonomous walking, fixed-axis rotation, sound and light synchronization, and simple body movements, significantly improving interactivity and playability compared to traditional static toys. However, after long-term market research and technical verification, it has been found that current mainstream electric doll products still have significant technical shortcomings and experience defects, making it difficult to meet the high-level needs of children and young consumers for playability, novelty, and scene adaptability of toys.

[0003] Currently, most electric dolls on the market use a fixed appearance design. All dynamic movements are based on a single fixed form, and they can only demonstrate functions such as walking and rotating within the same appearance. They cannot automatically switch between different appearances through structural changes. For example, common electric princess dolls can only perform simple actions in a fixed princess pose, and electric ornaments can only rotate and display with a fixed appearance. The appearance of the toys does not change from beginning to end, and the gameplay is highly fixed. Children easily lose interest after a short period of play due to a lack of novelty, resulting in a short product life cycle, low user stickiness, and a large number of toys being idle shortly after purchase, causing unnecessary consumer waste.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve one of the aforementioned technical problems, this application provides a doll with a skirt that can move up and down.

The intermittent gear is provided with two arc-shaped racks spaced apart in the circumferential direction, and a concave arc-shaped strip is provided between the two arc-shaped racks; The main gear and the intermittent gear have a linked rotation state and a non-linked rotation state. In the linked rotation state, the arc-shaped racks of the main gear and the intermittent gear mesh with each other. In the non-linked rotation state, the convex arc-shaped rack of the main gear slides with the concave arc-shaped rack of the intermittent gear. The main gear rotates while the intermittent gear is stationary.

[0011] Optionally, when the skirt piece swings upward to its limit position, a convex arc-shaped strip of the main gear slides into contact with a concave arc-shaped strip of the intermittent gear, so that the skirt piece remains in a certain state for a certain period of time. When the skirt piece swings downward to its limit position, the other convex arc strip of the main gear slides into contact with the other concave arc strip of the intermittent gear, so that the skirt piece remains in a certain state for a certain period of time.

[0012] Optionally, the drive mechanism includes a motor and a wheel system; The input gears of the motor and gear train mesh with each other; The main gear is provided with a gear ring, which meshes with a gear on the gear train.

One end of the support rod extends to the bottom of the main shell and is connected to the support leg. The linkage gear is disposed on the support rod. The main gear has a plane on one side along the thickness direction, and an arc-shaped rib is provided on the plane. The arc-shaped rib has a top end face, and both ends of the top end face extend smoothly to the plane.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0021] In the description of this application, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] See Figures 1 to 9 As shown, this application embodiment provides a doll with a movable skirt, including a main shell 1, multiple skirt pieces 2, and a drive mechanism 3. Each skirt piece 2 is arranged sequentially around the circumference of the main shell 1, and each skirt piece 2 is hinged to the main shell 1. Each skirt piece 2 is provided with a swing gear 21. The drive mechanism 3 is located inside the main shell 1 and includes a lifting frame 31, which is slidably disposed inside the main shell 1. Multiple first racks 311 are provided on the lifting frame 31, and each first rack 311 is arranged sequentially around the circumference of the lifting frame 31. Each first rack 311 on the lifting frame 31 meshes with the swing gear 21 on the corresponding skirt piece 2. The lifting movement of the lifting frame 31 of the drive mechanism 3 drives each skirt piece 2 to swing up and down.

[0024] The doll with a movable skirt provided in this application uses the lifting frame 31 to drive the circumferentially arranged first rack 311 to move synchronously, which in turn drives all the skirt pieces 2 to swing up and down synchronously through gear meshing, enabling a smooth transition between "princess mode" and "cake mode". When the skirt swings downwards, the doll's upper body and head are exposed, presenting a complete princess doll form; when the skirt swings upwards, the doll's upper body and head are covered, presenting an overall creative cake form, achieving a dual-form play effect. This solves the technical problem of traditional electric toys being able to only display a single form and lacking fun, effectively extending the toy's play life cycle and increasing user stickiness.

[0025] The doll with movable skirt provided in this application adopts a transmission structure of "multiple sets of first racks 311 distributed circumferentially on the lifting frame 31 and each skirt piece 2 independently configured with swing gears 21". A single lifting action of the lifting frame 31 can synchronously drive all skirt pieces 2 to complete a consistent swinging action. The swinging angle and movement speed of each skirt piece 2 are completely synchronized, and there will be no problems of misalignment, jamming or asynchrony. The form switching process is smooth and soft, presenting a coherent and natural deformation visual effect, which greatly improves the viewing experience and interactive quality of the toy.

[0026] In some possible implementations, the oscillating gear 21 includes an arc segment 211 and a plurality of protruding teeth 212, with each of the protruding teeth 212 and the arc segment 211 arranged sequentially around a circular trajectory. When the skirt piece 2 swings to its limit position, the first rack 311 and the corresponding arc segment 211 come into contact.

[0027] The transmission swing stage of the skirt: When the lifting frame 31 moves up and down along the height direction of the main shell 1, the first rack 311 on the lifting frame 31 first engages with the convex tooth 212 of the swing gear 21. As the first rack 311 moves synchronously with the lifting frame 31, the swing gear 21 is driven to rotate around the hinge axis of the skirt piece 2 through tooth engagement, thereby driving the skirt piece 2 to synchronously complete the upward or downward swing action and realize the form switching.

[0028] Limit shape-preserving stage: When the skirt piece 2 swings to its upper / lower limit position, all the protrusions 212 of the swing gear 21 disengage from the first rack 311. At this time, the arc segment 211 of the swing gear 21 and one end of the first rack 311 enter a contact engagement state. Even if the lifting frame 31 continues to move in the original direction, the first rack 311 will only slide relative to the surface of the arc segment 211 and will not drive the swing gear 21 to continue rotating. The skirt piece 2 can then remain stationary at the swing limit position, achieving stable shape preservation.

[0029] Reverse switching stage: When the lifting frame 31 moves in the reverse direction, the first rack 311 slides in the reverse direction along the arc segment 211 to the meshing position of the convex tooth 212, re-engages with the convex tooth 212, and drives the swing gear 21 to rotate in the reverse direction again, driving the skirt piece 2 to swing to another extreme position, completing the reverse form switching.

[0030] This structure achieves automatic shape retention through pure mechanics, eliminating the need for additional locking mechanisms. Through the purely mechanical design of the "difference in the rotation radius between the convex tooth 212 and the arc segment 211," the switching between "transmission swinging" and "limit shape retention" states can be automatically completed solely by the dimensional difference of the swing gear 21. This eliminates the need for additional locking mechanisms such as buckles, locking pins, or electromagnets, significantly simplifying the overall structure of the doll and reducing assembly costs and the probability of structural failure.

[0031] Furthermore, with the arc segment 211 and the first rack 311 in sliding engagement, the skirt piece 2 will not sway additionally as the lifting frame 31 continues to move. This ensures that the skirt piece 2 stops precisely at the preset limit position, avoiding structural interference and gear tooth dislodgement caused by excessive swaying. It also keeps the display status of the princess form and cake form stable, preventing the skirt from becoming loose or falling back on its own, thus ensuring the complete display effect of both forms.

[0032] The transition from meshing transmission to sliding conformal transmission is smooth through the arc surface, without any hard limit collision impact. The start and stop action of the skirt piece 2 is gentle and smooth, without any jamming or abnormal noise, which greatly improves the quality of the toy's operation. At the same time, the sliding contact of the arc surface can also protect the teeth of the rack and gear, preventing the teeth from being squeezed and damaged at the limit position, and extending the service life of the transmission structure.

[0033] Furthermore, the shape-holding time of the skirt piece 2 at the extreme position can be flexibly controlled by adjusting the arc length of the arc segment 211. The longer the arc length of the arc segment 211, the longer the relative sliding stroke of the first rack 311 along the arc segment 211, and the longer the shape-holding time of the skirt piece 2. Different shape-holding times can be flexibly adapted according to the needs of the play. There is no need to adjust the overall transmission logic; only the structural parameters of the swing gear 21 need to be modified, which can be achieved. The structure is highly adaptable.

[0034] In some possible implementations, the drive mechanism 3 includes a drive gear 32 rotatably mounted on the main housing 1. A second rack 312 is mounted on the lifting frame 31, extending along the height direction of the main housing 1 and meshing with the drive gear 32. Rotation of the drive gear 32 drives the lifting frame 31 to move up and down. The first rack 311 and the second rack 312 move synchronously. After the toy is activated, the continuous rotation of the drive gear 32 drives the lifting frame 31 to move up and down repeatedly via the second rack 312, thereby continuously driving the skirt piece 2 to swing back and forth between its two extreme positions. The entire process can automatically cycle through dual-form transformations without manual intervention, resulting in a high degree of automation and a smooth play experience.

[0035] Furthermore, by engaging the drive gear 32 with the second rack 312 extending along the height direction on the lifting frame 31, the rotational motion of the drive gear 32 can be directly converted into the linear lifting motion of the lifting frame 31. The transmission path is short and the power transmission efficiency is high. At the same time, the lifting stroke can be precisely controlled by the rotation angle of the drive gear 32, thereby precisely controlling the swing amplitude of the skirt piece 2 to ensure the accuracy of the form switching. Moreover, the transmission structure is compact and can be completely built into the main shell 1 without occupying extra space.

[0036] In some possible implementations, the drive mechanism 3 includes a rotating wheel 33 and a horizontal sliding plate 34. The horizontal sliding plate 34 is slidably disposed within the main housing 1, and a third rack 341 and an action groove 342 are provided on the horizontal sliding plate 34. The third rack 341 meshes with the drive gear 32. The rotating wheel 33 is rotatably disposed within the main housing 1, and the rotating wheel 33 has an eccentric shaft 331 extending into the action groove 342. The rotation of the rotating wheel 33 can drive the horizontal sliding plate 34 to reciprocate.

[0037] The rotating wheel 33 receives power from the front end and rotates continuously around its fixed axis of rotation. The eccentric shaft 331, fixed to the end face of the rotating wheel 33, revolves synchronously with the rotating wheel 33 in a circular trajectory. The eccentric shaft 331 extends and is embedded in the action groove 342 of the horizontal sliding plate 34. Since the horizontal sliding plate 34 can only slide in a directional direction along the horizontal direction of the main shell 1, the circular motion of the eccentric shaft 331 is constrained by the side wall of the action groove 342 and decomposed into a horizontal pushing and pulling force. When the rotating wheel 33 rotates continuously, the eccentric shaft 331 will drive the horizontal sliding plate 34 to make a continuous reciprocating linear motion of "forward-backward" in the horizontal direction. For each rotation of the rotating wheel 33, the horizontal sliding plate 34 completes one complete reciprocating translational stroke.

[0038] During the reciprocating translation of the horizontal sliding plate 34, the third rack 341 fixed on it moves synchronously with the sliding plate, and drives the drive gear 32 to rotate alternately in the forward and reverse directions through tooth meshing. When the drive gear 32 rotates in the forward and reverse directions, it meshes with the second rack 312 arranged along the height direction on the lifting frame 31, converting its own rotational motion into the upward and downward linear motion of the lifting frame 31. Finally, through the meshing transmission between the first rack 311 on the lifting frame 31 and the swing gear 21 of each skirt piece 2, all skirt pieces 2 are driven to synchronously complete the upward and downward swinging motion, realizing the automatic switching between princess form and cake form.

[0039] It adopts a crank-slider transmission structure of "eccentric rotating wheel 33 and horizontal sliding plate 34", which can transform the continuous rotational motion of the rotating wheel 33 into a smooth and uniform horizontal reciprocating motion, avoiding the sudden speed change caused by direct transmission. This makes the lifting action of the lifting frame 31 and the swinging action of the skirt piece 2 smoother and gentler, and the form switching process is smooth and natural without any abrupt jolts, greatly improving the dynamic display quality of the toy.

[0040] This reciprocating transmission structure can directly cooperate with the intermittent gear 36 mechanism at the rear end. By controlling the start and stop of the rotating wheel 33, the movement timing of the horizontal slide 34 can be controlled, easily realizing the cyclic action logic of "swing-shape preservation-reverse swing-shape preservation". This provides a stable transmission foundation for subsequent linked gameplay such as shape preservation and rotation, and has strong gameplay expandability.

[0041] In some possible implementations, the drive mechanism 3 includes a main gear 35 and an intermittent gear 36, with the rotating wheel 33 connected to the intermittent gear 36. The main gear 35 has two arc-shaped racks spaced apart circumferentially, with a convex arc-shaped strip 351 positioned between the two racks. The center of the convex arc-shaped strip 351 is located on the rotation axis of the main gear 35. The intermittent gear 36 has two arc-shaped racks spaced apart circumferentially, with a concave arc-shaped strip 361 positioned between the two racks. The main gear 35 and the intermittent gear 36 have a linked rotation state and a non-linked rotation state. In the linked rotation state, the arc-shaped racks of the main gear 35 and the intermittent gear 36 mesh. In the non-linked rotation state, the convex arc-shaped strip 351 of the main gear 35 slides against the concave arc-shaped strip 361 of the intermittent gear 36, and the main gear 35 rotates while the intermittent gear 36 remains stationary.

[0042] In some possible implementations, when the skirt piece 2 swings upward to its limit position, a convex arcuate strip 351 of the main gear 35 slides into contact with a concave arcuate strip 361 of the intermittent gear 36, causing the skirt piece 2 to maintain its state for a certain period of time. When the skirt piece 2 swings downward to its limit position, another convex arcuate strip 351 of the main gear 35 slides into contact with another concave arcuate strip 361 of the intermittent gear 36, causing the skirt piece 2 to maintain its state for a certain period of time.

[0043] Linked rotation state (skirt swing stage): The main gear 35 receives power and rotates continuously. When the arc-shaped rack on the main gear 35 rotates to align with the arc-shaped rack on the intermittent gear 36, the two sets of arc-shaped racks enter a meshing state. At this time, the rotational power of the main gear 35 is transmitted to the intermittent gear 36 through the rack meshing, causing the intermittent gear 36 to rotate synchronously. Since the intermittent gear 36 is fixedly connected to the rotating wheel 33 that drives the skirt, the rotation of the intermittent gear 36 will drive the rotating wheel 33 to rotate synchronously. Then, through the transmission chain of the horizontal slide plate 34, the drive gear 32, and the lifting frame 31, all skirt pieces 2 are ultimately driven to complete the upward or downward swinging motion synchronously, realizing the switching between princess form and cake form.

[0044] Non-linkage rotation state (skirt shape-preserving stage): When the arc-shaped rack of the main gear 35 completes its meshing stroke and disengages from the intermittent gear 36, the skirt piece 2 swings to its upper / lower limit position. At this time, the outwardly convex arc-shaped strip 351 on the main gear 35 rotates to align with the inwardly concave arc-shaped strip 361 of the intermittent gear 36. The arc surface of the outwardly convex arc-shaped strip 351 and the arc surface of the inwardly concave arc-shaped strip 361 form a sliding fit, and the structure enters the non-linkage rotation state: the main gear 35 continues to rotate, but the outwardly convex arc-shaped strip 351 only slides relative to the inner wall of the inwardly concave arc-shaped strip 361 and does not transmit rotational power to the intermittent gear 36, which remains stationary. The rear-end rotating wheel 33, the horizontal sliding plate 34, and the lifting frame 31 all remain stationary synchronously, so the skirt piece 2 can stably stay at the swing limit position, achieving continuous shape preservation in the princess or cake shape.

[0045] State cycle switching: The main gear 35 continues to rotate, the outward convex arc strip 351 slides out of the engagement range of the inward concave arc strip 361, the next set of arc racks of the main gear 35 meshes with the corresponding arc rack of the intermittent gear 36 again, the structure switches back to the linkage rotation state, drives the intermittent gear 36 to rotate in the opposite direction, drives the skirt piece 2 to swing to another extreme position, and automatically completes the cycle action of "swing-conservation-reverse swing-reverse conservation".

[0046] This structure uses pure mechanical means to achieve intermittent transmission. It does not require electrical control or additional locking structures. It can automatically achieve the intermittent transmission effect of "power transmission-power disconnection" simply by alternating the arc rack and arc bar of the main gear 35 and the intermittent gear 36. It does not require additional components such as sensors, electrical control programs, or locking buckles. It relies entirely on the pure mechanical structure to complete the automatic switching of "skirt swing-limit shape preservation". The structure is simple and reliable, which greatly reduces production and maintenance costs.

[0047] Furthermore, it maintains a stable and reliable shape, resulting in excellent form display. In the non-linked state, the convex arc strip 351 and the concave arc strip 361 fit together to form a natural limiting constraint, preventing the intermittent gear 36 from rotating on its own. The skirt piece 2 can be stably maintained at its limit position without any issues such as self-falling, loosening, or displacement. The display state of the princess form and the cake form is stable, ensuring that the toy's appearance display effect is complete and consistent.

[0048] In some possible implementations, the drive mechanism 3 includes a motor 37 and a gear train 38. The input gears of the motor 37 and the gear train 38 mesh with each other. A gear ring is provided on the main gear 35, and the gear ring meshes with a gear on the gear train 38. The motor 37 and the gear train 38 provide power to the main gear 35, and the gear train 38 can achieve the effect of speed reduction and torque increase, providing sufficient driving force for the linkage between the lifting frame 31 and the skirt pieces 2, ensuring sufficient power for the synchronous swing of multiple sets of skirt pieces 2. At the same time, the motor 37 drive realizes the full automation of form switching, without the need for manual operation by the user, further reducing the threshold for play and enhancing the technological feel and interactive experience of the toy.

[0049] In some possible implementations, the doll with a movable skirt also includes a telescopic support assembly 4, which includes a support rod 41, a linkage gear 42, and a support leg 43. The support rod 41 extends along the height direction of the main shell 1 and is slidably connected to the main shell 1. One end of the support rod 41 extends to the bottom of the main shell 1 and is connected to the support leg 43. The linkage gear 42 is disposed on the support rod 41. The main gear 35 has a plane 352 on one side along the thickness direction. An arc-shaped rib 3521 is provided on the plane 352. The arc-shaped rib 3521 has a top end face, and both ends of the top end face extend smoothly to the plane 352. During the rotation of the main gear 35, the support rod 41 can be pushed by the top end face of the arc-shaped rib 3521, so that the support rod 41 extends outward to the bottom of the main shell 1, the support leg 43 is supported on the support surface, the linkage gear 42 moves down and meshes with a gear on the gear train 38, and the main shell 1 rotates relative to the support rod 41.

[0050] Princess Mode Walking Stage: When the doll is in princess mode (skirt piece 2 swings downwards, revealing the doll's head and upper body), the main gear 35 rotates to an angle where the arc-shaped rib 3521 is not in contact with the support rod 41, the support rod 41 is in a retracted state, and the support legs 43 are stored at the bottom of the main shell 1. A walking mechanism is also included; at this time, the doll's walking mechanism contacts the support surface, allowing the doll to walk and move autonomously on the support surface. The linkage gear 42 on the support rod 41 is in a high position, separated from the power wheel system 38, and the main shell 1 does not rotate.

[0051] Form switching and support extension stage: The main gear 35 receives power and rotates continuously. First, it drives the skirt piece 2 to swing upward through the intermittent gear 36 mechanism, and the doll begins to switch from princess form to cake form. At the same time, the arc-shaped rib 3521 on the end face of the main gear 35 rotates synchronously with the main gear 35. The end face of the arc-shaped rib 3521 gradually contacts the top of the support rod 41 and begins to smoothly push the support rod 41 to extend downward along the height direction of the main shell 1.

[0052] Cake-shaped rotating performance stage: When the skirt piece 2 swings upward to its limit and the doll completely switches to cake shape, the main gear 35 enters a non-linkage shape-preserving state, and the skirt remains stationary in cake shape; at this time, the top end face of the arc-shaped protrusion 3521 fully pushes the support rod 41, the support rod 41 extends downward to its maximum stroke, and the bottom support leg 43 supports the support surface, lifting the entire main shell 1 upward. The walking mechanism rises with the main shell 1 and detaches from the support surface; at the same time, the linkage gear 42 on the support rod 41 moves down synchronously with the support rod 41 and enters a meshing state with the corresponding transmission gear of the gear train 38. The power of the main gear 35 is transmitted to the linkage gear 42 through the gear train 38, thereby driving the entire main shell 1 to rotate around the axis of the support rod 41, realizing a 360° automatic rotating performance in cake shape.

[0053] Reset and switching phase: The main gear 35 continues to rotate, the arc-shaped rib 3521 gradually detaches from the top of the support rod 41, the support rod 41 retracts upward, the support leg 43 is simultaneously retracted, the main shell 1 falls back to the support surface, and the walking mechanism re-contacts the support surface; the linkage gear 42 moves upward with the support rod 41 and separates from the wheel system 38, and the rotation stops; at the same time, the main gear 35 re-enters the linkage state, causing the skirt piece 2 to swing downward, resetting to the princess form, and the walking mechanism resumes driving the doll to restore its autonomous walking function.

[0054] This structure enables dual-mode matching and dual-play, significantly enhancing playability. It achieves a synergistic match between appearance and core gameplay. In princess mode, the doll can walk independently, suitable for children's interactive play and role-playing scenarios; in cake mode, it automatically rises and rotates to perform, suitable for desktop decorations, scene decorations, and birthday atmosphere displays. It truly realizes "one item, two ways to play; one scene, one way to play," completely solving the pain points of traditional electric toys' single gameplay and lack of novelty, and greatly extending the toy's lifespan.

[0055] A single power source enables full linkage of multiple actions, with industry-leading structural integration: relying solely on the power output of the same main gear 35, it can simultaneously complete three core actions: "skirt shape switching + support rod 41 telescopic lifting + walking / rotation function switching". There is no need to set up separate rotation drive motor 37 and lifting drive mechanism 3, which greatly simplifies the internal structure of the doll, reduces production and manufacturing costs, and also reduces the probability of failure and assembly difficulty caused by multiple power sources.

[0056] In some possible implementations, the telescopic support assembly 4 includes an elastic element 44. The elastic element 44 is disposed within the main housing 1, with one end abutting against the linkage gear 42. As the main gear 35 rotates until the arc-shaped rib 3521 gradually disengages from the support rod 41, the support rod 41 gradually moves upward under the action of the elastic element 44, causing the linkage gear 42 to separate from the gears on the gear train 38. The elastic element 44 provides a reset driving force to the support rod 41. When the main gear 35 rotates until the arc-shaped rib 3521 disengages from the support rod 41, the elastic element 44 automatically pushes the support rod 41 upward to reset, simultaneously causing the linkage gear 42 to automatically separate from the gear train 38, stopping the rotation of the main housing 1. This automatically completes the "support rotation - retraction stop" action cycle without the need for an additional reset mechanism. The action logic is smooth and coherent, the structure is simple and reliable, and it further reduces the number of parts and assembly costs.

[0057] In some possible implementations, a clutch element 45 is provided on the support rod 41. The clutch element 45 includes an elastic strip 451 and a clutch protrusion 452 provided on the elastic strip 451. A groove 421 is provided on one side of the linkage gear 421 along its thickness direction, and a plurality of clutch grooves 422 are provided on the peripheral wall of the groove 421. The linkage gear 42 is rotatably sleeved on the support rod 41. The clutch element 45 is located in the groove 421, and the clutch protrusion 452 of the clutch element 45 is embedded in the clutch groove 422. The elastic element 44 abuts against the side of the linkage gear 42 opposite to the clutch element 45. The clutch 45 and the clutch groove 422 of the linkage gear 42 cooperate to form an overload protection structure. When the doll is blocked by an external force during rotation, or when the support rod 41 is blocked from extending, the clutch protrusion 452 will overcome the elastic force of the elastic strip 451 and slide out of the clutch groove 422, allowing the linkage gear 42 to rotate relative to the support rod 41. This prevents the motor 37 and the transmission structure from being damaged due to overload, effectively improving the toy's resistance to violent play and structural durability.
