Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a hand-held electric toy. Background Technology

[0002] With the increasing abundance of electronic products, electric toys are also becoming more diverse. Imitation toys are a type of electronic toy that entertains people by mimicking various animals and making different movements. Of course, toys imitating dogs and cats, being among the most popular and beloved animals, are naturally popular. Currently, there are electric toys on the market that can vividly mimic the waving movements of animals like dogs and cats. The swing drive mechanism generally uses a motor that drives a gear set in both forward and reverse directions, and the gear set then transmits power to the swinging component, causing the swing arm to swing with the swinging component. However, this type of electric toy with waving movements is not yet perfect. Over time, collisions or other factors inevitably cause the internal gear set to shift, or age, leading to gear slippage or freewheeling, causing the swinging component to malfunction. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a swinging electric toy that uses electromagnetic drive instead of traditional gear transmission, making the swinging arm movement trajectory of the toy more closely resemble the movements of real animals and enhancing the entertainment experience.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electric swinging toy includes a toy body, inside which a swinging drive assembly is provided. The swinging drive assembly includes a swinging component rotatably connected inside the toy body and a drive coil for driving the swinging component. When energized, the drive coil generates an alternating magnetic field, which drives the swinging component to swing back and forth around its rotation axis. The swinging component and a swing arm on the toy body form a transmission engagement, so that the swing arm swings with the swinging component.

[0006] Furthermore, the toy body has a battery compartment inside, and the output end of the battery compartment is electrically connected to the power input end of the PCB board through a conductor; the pins of the drive coil are soldered to the power supply circuit of the PCB board, and the PCB board converts the DC power output from the battery compartment into alternating current and outputs it to the drive coil.

[0007] Furthermore, the upper part of the PCB board is provided with a mounting portion for accommodating the drive coil.

[0008] Furthermore, the swing component has a cross-shaped or T-shaped structure, including a vertical section and a horizontal section of integral structure; the bottom of the vertical section of the swing component is provided with a storage part for accommodating magnetically conductive material, and the single-sided extension end of the horizontal section of the swing component is provided with a connecting part for transmission with the swing arm.

[0009] Furthermore, the connecting part is provided with an assembly port extending through its axis, and the inner circumferential surface of the assembly port is provided with an anti-rotation limiting port; the swing arm includes a rear shell and a front shell that are fastened together, wherein the rear shell extends to form a connecting shaft one, and the outer circumferential surface of the connecting shaft one is provided with an anti-rotation protrusion that fits into the anti-rotation limiting port, and the connecting shaft one and the assembly port form an insertion fit; the connecting shaft one is provided with a regular polygonal through groove inside, and the front shell extends to form a connecting shaft two, and the connecting shaft two and the regular polygonal through groove form an insertion fit.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] An electric swinging toy is provided, in which a swinging drive assembly is installed inside the toy body. The swinging drive assembly includes a swinging component rotatably connected inside the toy body and a drive coil that drives the swinging component. When energized, the drive coil generates an alternating magnetic field, which drives the swinging component to swing back and forth around its rotation axis. The swinging component and the swing arm on the toy body form a transmission engagement, causing the swing arm to swing in accordance with the swinging component. By directly driving the swinging component to swing back and forth through the alternating magnetic field generated by the drive coil, the existing gear transmission technology is replaced, fundamentally avoiding the mechanical wear problem of gears and the slippage, free spin, or displacement problems caused by collisions and aging of gear sets, thus fundamentally eliminating the risk of gear transmission failure. The complex gear set structure is eliminated, the drive assembly is simplified, production and maintenance costs are reduced, mechanical wear is reduced, and the toy's service life is extended. The electromagnetic drive has a faster response speed, smoother action transitions, no mechanical lag of traditional gear transmissions, and the movement trajectory of the swing arm is closer to the movement of real animals, enhancing the entertainment experience.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figure 1-4 As shown, this utility model provides a technical solution: a swinging electric toy, including a toy body 1, with a swinging drive assembly inside the toy body 1. The swinging drive assembly includes a swinging component 2 rotatably connected inside the toy body 1 and a drive coil for driving the swinging component 2. When energized, the drive coil generates an alternating magnetic field, which drives the swinging component 2 to swing back and forth around its rotation axis. The swinging component 2 and the swing arm 10 on the toy body 1 form a transmission connection, causing the swing arm 10 to swing along with the swinging component 2. By directly driving the swinging component 2 to swing back and forth through the alternating magnetic field generated by the drive coil, the existing gear transmission is replaced, fundamentally avoiding the mechanical wear problem of gears and preventing slippage, freewheeling, or displacement caused by collisions or aging of the gear set, thus eliminating the risk of gear transmission failure. The complex gear set structure is eliminated, simplifying the drive assembly, reducing production and maintenance costs, reducing mechanical wear, and extending the toy's lifespan. The electromagnetic drive has a faster response speed, smoother action transitions, and no mechanical lag like in traditional gear transmissions. The movement trajectory of the swing arm 10 is closer to the movements of real animals, enhancing the entertainment experience.

[0019] See Figures 2-3 As shown, the toy body 1 has a battery compartment 3 inside. The output end of the battery compartment 3 is electrically connected to the power input end of the PCB board 4 through a conductor. The pins of the drive coil are soldered to the power supply circuit of the PCB board 4. The PCB board 4 converts the DC power output from the battery compartment 3 into alternating current and outputs it to the drive coil. The upper part of the PCB board 4 has a mounting part 5 for accommodating the drive coil. The conductor is a conductive spring or wire.

[0020] See Figures 2-3As shown, the swing element 2 is designed with a cross-shaped or T-shaped structure, including a vertical section 20 and a horizontal section 21 of integral structure. The bottom of the vertical section 20 of the swing element 2 is provided with a storage part 22 for accommodating magnetically conductive material, and one side of the horizontal section 21 of the swing element 2 has a connecting part 23 that is connected to the swing arm 10 for transmission. The magnetically conductive material is positioned directly above the drive coil, enabling efficient coupling between the magnetically conductive material and the electromagnetic field, resulting in high energy utilization and improved driving efficiency.

[0021] See Figures 3-4 As shown, the connecting part 23 has an assembly port 230 extending through its axis, and an anti-rotation limiting port 231 is provided on the inner circumferential surface of the assembly port 230. The swing arm 10 includes a rear shell and a front shell that are fastened together. The rear shell extends to form a connecting shaft 100, and the outer circumferential surface of the connecting shaft 100 has an anti-rotation protrusion 101 that fits into the anti-rotation limiting port 231. The connecting shaft 100 and the assembly port 230 form a plug-in fit. The connecting shaft 100 has a regular polygonal through groove 102 inside, and the front shell extends to form a connecting shaft 2, which forms a plug-in fit with the regular polygonal through groove 102. The swing arm 10 forms a double plug-in fit with the swing member 2 through the connecting shaft 100 in the rear shell and the connecting shaft 2 in the front shell, so that the swing arm 10 and the swing member 2 are tightly connected, improving the swing continuity of the swing arm 10, making the movement smooth and natural, and preventing the connection from loosening during the swing.

[0022] Working principle: The battery compartment 3 has a built-in battery that provides linear power to the PCB board 4 through conductive springs / wires. The PCB board 4 converts the DC power into an alternating current of a specific frequency, and through the drive coil pins soldered on the power supply circuit, it forms a periodically changing alternating current output. Under the action of the alternating current, the drive coil periodically changes the direction of the magnetic field (i.e., generates an alternating magnetic field). The bottom of the vertical section 20 of the swinging component 2 is provided with a magnetic material (such as an iron core), which is repeatedly magnetized in the alternating magnetic field and subjected to alternating attraction and repulsion of the magnetic field force, thereby swinging back and forth around the rotation axis (i.e., the horizontal section 21), so that the swing arm 10 swings with the swinging component 2 (that is, the working principle of a mover and a stator).
