Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to an electric rocking toy. Background Technology

[0002] Electric rocking toys, as early childhood entertainment and sensory training devices, require stable and smooth swinging as their core function, while also ensuring safety, durability, and ease of assembly and maintenance. While existing products can achieve basic swinging, structural design flaws prevent them from meeting these core requirements. Specific technical problems are as follows, and these are the pain points that this invention specifically addresses:

[0003] 1. Defects in the transmission structure lead to poor oscillation smoothness and uncontrollable stroke. Existing products mostly adopt the "motor + gear direct drive" or "motor + connecting rod hinge" scheme: gear direct drive has a small oscillation amplitude, and the meshing gap is prone to causing jerking noise and large energy loss; the connecting rod hinge is prone to wear and loosening at the hinge point under high-frequency oscillation, resulting in trajectory deviation and unstable amplitude. Moreover, most products lack a precise limiting structure, and the oscillation stroke relies on the self-constraint of the transmission mechanism, which is prone to deformation or damage to the drive module due to excessive amplitude impacting components;

[0004] 2. Inadequate connection structure leads to poor stability, short lifespan, and high maintenance costs. The connections between the swinging components and the drive module, and between the top actuator and the swinging components, are mostly interference fits or strong adhesives: interference fits lack anti-loosening designs, and high-frequency vibrations easily widen the gaps, causing loosening and detachment; strong adhesives are non-removable, and internal failures render the toy unusable, making individual repair impossible. Furthermore, the rotating parts lack friction-reducing and reinforcing structures, resulting in high frictional resistance and easy stress deformation, further shortening the lifespan.

[0005] Therefore, the development of an electric rocking toy that specifically addresses the above problems and balances smooth and controllable swinging, stable protection, and easy assembly and disassembly has become an urgent need in the industry. Utility Model Content

[0006] The purpose of this invention is to provide an electric rocking toy that solves the technical problems of existing electric rocking toys, such as uneven swinging, loose connections, and poor protection, and achieves stable and controllable swinging with a durable structure.

[0007] To achieve the above objectives, this utility model provides an electric rocking toy, including a base, a rocking drive mechanism, a flexible covering structure, and a top actuator. The two ends of the flexible covering structure are respectively connected to the base and the top actuator and enclose a receiving space. The rocking drive mechanism is disposed in the receiving space and is drivenly connected to the top actuator to drive the top actuator to complete a preset rocking action.

[0008] The swing drive mechanism includes a power output unit, an eccentric transmission component, and a swing bearing component;

[0009] The swing bearing member is rotatably engaged with the base, and the swing bearing member is connected to the top actuator to drive them to swing synchronously.

[0010] The power output unit is located within the accommodating space, and the power output end of the power output unit is connected to the eccentric transmission component.

[0011] The non-rotation center position of the eccentric transmission component is driven to engage with the swing bearing component. The power output unit drives the eccentric transmission component to rotate, and the eccentric action pushes the swing bearing component to reciprocate around the rotation engagement point between it and the base.

[0012] Preferably, the power output unit includes a power housing, a multi-stage transmission assembly, and a drive source; the multi-stage transmission assembly is built into the power housing, the drive source is fixed to the power housing, the power output end of the drive source is connected to the input end of the multi-stage transmission assembly, and the output end of the multi-stage transmission assembly is connected to the eccentric transmission component to drive the eccentric transmission component to rotate.

[0013] Preferably, the opposite sides of the swing bearing extend outward to form a rotating connection portion, and the rotating connection portion is provided with a rotating fitting hole; the corresponding sides of the power receiving housing are provided with rotating fitting posts, and the rotating fitting holes are adapted to be inserted into the rotating fitting posts for rotatable engagement between the swing bearing and the power receiving housing.

[0014] Preferably, the rotating connection portion is provided with a reinforcing guide rib, and the contact surface between the rotating mating hole and the rotating mating column is provided with a friction-reducing groove; the power receiving housing is provided with a limiting component, the reinforcing guide rib is located above the limiting component, and the edge of the rotating connection portion abuts against the limiting component to limit the swing stroke of the swing bearing.

[0015] Preferably, the eccentric transmission component includes an eccentric base plate and an eccentric mating column located at a position other than the rotation center of the eccentric base plate; the swing bearing member has a movable groove on the side facing the eccentric transmission component, and the eccentric mating column extends into the movable groove and can move relative to the movable groove.

[0016] Preferably, the swing bearing has a connecting column protruding on the side facing the top actuator, and the top actuator has a mating connecting groove. The connecting column is adapted to be inserted into the mating connecting groove to realize the connection between the swing bearing and the top actuator.

[0017] Preferably, the outer periphery of the connecting column is provided with an annular boss, the height of which is lower than the height of the connecting column.

[0018] Preferably, the end of the connecting column facing the mating connecting groove is provided with a spherical connector; the inner wall of the mating connecting groove is provided with a limiting block, which engages with the spherical connector to realize a detachable limiting connection between the connecting column and the mating connecting groove.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model, through the innovative design of the eccentric transmission component, transforms the rotational motion of the motor into the reciprocating oscillation of the swing bearing component. The power transmission path is short and the energy loss is small, avoiding the defects of traditional gear direct drive with small amplitude and linkage transmission with easy jamming, thus improving the smoothness of the swing. At the same time, the limiting component cooperates with the rotating connection part to accurately limit the swing stroke, avoid component collision caused by excessive amplitude, and ensure that the top actuator swings stably along the preset trajectory.

[0021] 2. This utility model strengthens the structural strength by reinforcing the guide ribs of the rotating connection part, reduces friction loss by the friction-reducing groove, and improves the durability of the rotating fit; the spherical connector of the connecting column engages with the limiting block, and combined with the anti-loosening and vibration-damping effect of the annular boss, it realizes a detachable limiting connection, which completely solves the defects of traditional interference fit that is easy to loosen and adhesive that is not maintainable. Faulty parts can be replaced separately, which greatly reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0032] like Figure 1 As shown, an electric rocking toy includes a base 1, a rocking drive mechanism 2, a flexible covering structure 3, and a top actuator 4. The flexible covering structure 3 is an integrated elastic structure, specifically made of flexible fabric (such as Oxford cloth or knitted elastic fabric), with its edges sealed together by snaps and hot melt adhesive. It is fixed to the upper surface of the base 1 and the lower surface of the top actuator 4, forming a closed accommodating space 5. The rocking drive mechanism 2 is built into and confined within the accommodating space 5 and is eccentrically connected to the top actuator 4, driving the top actuator 4 to perform a controllable reciprocating rocking motion around a preset axis of the base 1. The flexible fabric has good extensibility and can elastically deform synchronously with the reciprocating rocking motion of the top actuator 4, avoiding interference with the rocking motion and solving the problem of existing rigid protective shells compressing the rocking amplitude. Simultaneously, the sealed connection method prevents dust, hair, and other foreign objects from entering the accommodating space 5, and the flexible material can buffer external collisions, preventing children from being squeezed by the rigid structure when touching it, thus balancing protection and safety.

[0033] Furthermore, such as Figure 2 , Figure 3As shown, the swing drive mechanism 2 includes a power output unit 6, an eccentric transmission component 7, and a swing bearing component 8. The power output unit 6 includes a power housing 9, a multi-stage transmission assembly 10, and a drive source 11. The drive source 11 uses a miniature DC geared motor, which is detachably fixed to the power housing 9 with bolts for easy maintenance and replacement. The multi-stage transmission assembly 10 uses multi-stage transmission gears and is integrally housed within the cavity of the power housing 9. The power housing 9 is made of one-piece ABS plastic, providing protection and fixation. The output shaft of the drive source 11 is connected to the multi-stage transmission assembly 10. After transmission through the gear set, speed reduction and torque increase are achieved, ensuring sufficient output torque to drive the top actuator 4 to swing smoothly. Simultaneously, the small gear meshing clearance reduces energy loss during power transmission. Combined with the fixing effect of the power housing 9, it prevents vibration and gear misalignment, improving transmission stability.

[0034] Furthermore, the eccentric transmission component 7 includes an eccentric base plate 18 and an eccentric mating post 19. The eccentric base plate 18 is made of a circular plastic plate and is coaxially fixed with the output shaft of the multi-stage transmission component 10. The eccentric mating post 19 is a cylindrical structure, integrally formed at the non-rotation center position (i.e., off-center from the center of the base plate) of the eccentric base plate 18, and is set perpendicular to the eccentric base plate 18. The swing bearing 8 has a movable groove 20 (using an oblong groove structure) on the side facing the eccentric transmission component 7, and the eccentric mating post 19 extends into the movable groove 20 to form a clearance fit. When the power output unit 6 drives the eccentric base plate 18 to rotate, the eccentric mating column 19 performs a circular motion, transmitting thrust through the side wall of the movable groove 20, converting the rotational motion into the reciprocating swing of the swing bearing 8. The power transmission path is direct, without the wear and looseness problems of connecting rods and hinges, and without the amplitude limitation of gear direct drive, effectively improving the smoothness of swing. At the same time, the length of the movable groove 20 is adapted to the movement trajectory of the eccentric mating column 19, which can help limit the swing amplitude, forming a double guarantee with the subsequent limiting component 17, further ensuring the stability of swing.

[0035] like Figure 3 , Figure 4 As shown, the swing bearing 8 adopts a one-piece molded plastic structure, with two symmetrical rotating connecting parts 12 extending outward from its opposite sides. Circular rotating fitting holes 13 are provided on the rotating connecting parts 12. Cylindrical rotating fitting posts 14 are integrally molded on the corresponding sides of the power housing 9. The rotating fitting holes 13 and rotating fitting posts 14 are fitted with a clearance fit, enabling a rotatable connection between the swing bearing 8 and the power housing 9. The one-piece molded rotating connecting parts 12 have higher structural strength. Combined with the precise fit between the rotating fitting holes 13 and rotating fitting posts 14, they provide a stable rotational fulcrum for the swing bearing 8, ensuring that the swing bearing 8 swings around a preset axis and avoiding trajectory deviation. Simultaneously, the clearance fit reduces rotational friction resistance, providing support for smooth swinging.

[0036] Furthermore, such as Figure 4 As shown, the upper surface of the rotating connection 12 is integrally formed with a reinforcing guide rib 15, which is arranged along the rotation radius direction and its extension direction is consistent with the swing trajectory of the swing bearing 8; the friction-reducing groove 16 is opened on the inner wall of the rotating mating hole 13; the side wall of the power receiving housing 9 is integrally formed with a limiting component 17 (a plastic block protrusion), which is located directly below the reinforcing guide rib 15 and corresponds to the edge position of the rotating connection 12. The reinforcing guide rib 15 enhances the structural rigidity of the rotating connection 12, disperses the stress generated during the swing, and prevents the rotating connection 12 from deforming due to high-frequency swing. At the same time, its guiding function can help limit the swing direction and prevent the swing bearing 8 from radially shifting. The friction-reducing groove 16 can further reduce the friction loss between the rotating mating hole 13 and the rotating mating column 14, extend the service life of the component, and solve the problem of high friction resistance in the existing rotating mating parts. The limiting component 17, by abutting against the edge of the rotating connection 12, precisely limits the maximum swing stroke of the swing bearing 8, preventing the eccentric mating column 19 from hitting the end of the movable groove 20 or the top actuator 4 from hitting the flexible covering structure 3 due to excessive amplitude, thus achieving "controllable amplitude swing" and protecting the internal components from damage.

[0037] Furthermore, such as Figure 5 As shown, a cylindrical connecting column 21 is integrally formed on the side of the swing bearing 8 facing the top actuator 4. A mating connecting groove 22 is provided on the lower surface of the top actuator 4. The connecting column 21 and the mating connecting groove 22 are adapted to be inserted into each other. The mating surfaces fit tightly to ensure that the swinging action of the swing bearing 8 can be synchronously transmitted to the top actuator 4, avoiding relative shaking.

[0038] The outer circumference of the connecting column 21 is integrally formed with an annular boss 23, which is located at one end near the swing bearing 8 and is lower than the height of the connecting column 21. During use, this increases the contact area of ​​the connection, disperses the lateral force generated by the swing, prevents stress concentration and deformation at the root of the connecting column 21, and simultaneously seals the connection gap, preventing dust from entering the mating surface and reducing wear. During maintenance, it can serve as a force application point, facilitating the prying of the connecting column 21 with tools for detachable separation, thus solving the problem of non-maintainable existing adhesive connections.

[0039] In addition, the free end of the connecting column 21 is provided with a spherical connector 24, which adopts an arc transition structure; the limiting block 25 consists of several protrusions, integrally formed on the inner wall of the mating connecting groove 22, and has a certain elastic deformation capability, allowing the spherical connector 24 to be inserted and limited. The snap-fit ​​between the spherical connector 24 and the limiting block 25 realizes a detachable limiting connection, which avoids the defects of easy loosening and falling off of interference fit, and overcomes the problem of non-removable adhesive. At the same time, the structure of the spherical connector 24 can adapt to slight angular offsets, ensuring that the connection part is not stuck when the top actuator 4 swings with the swing bearing 8, further improving the smoothness of swing. Combined with the anti-loosening effect of the annular boss 23, the connection stability is greatly improved.

[0040] Overall debugging and workflow: Start the drive source 11 (micro DC geared motor). The output shaft of the drive source 11 drives the multi-stage transmission assembly 10 (multi-stage transmission gear) to rotate. After reduction and torque increase, it drives the eccentric base plate 18 to rotate. The eccentric mating column 19 moves in a circular motion with the eccentric base plate 18, slides back and forth in the movable groove 20, and pushes the swing bearing 8 to swing back and forth around the rotating mating column 14 (e.g., Figure 6 (As shown); the swing bearing 8 is stably connected to the top actuator 4 via the connecting column 21, causing the top actuator 4 to swing synchronously. The flexible covering structure 3 elastically deforms with the swinging motion, without motion interference; when the edge of the rotating connecting part 12 abuts against the limiting part 17, the swing reaches its maximum stroke and swings in the opposite direction, forming a continuous and stable reciprocating swing (as shown). Figure 7 (As shown).
