Description

Technical Field

[0001] This utility model relates to the field of biomimetic toy technology, and more specifically, to a swing mechanism and a simulation toy. Background Technology

[0002] In the design of dynamic biomimetic toys, toy fish are a typical example. They use an internal drive mechanism to achieve the periodic swinging of the fish's tail, simulating the swimming posture of real fish and enhancing interactivity and realism. In this type of structure, a swinging mechanism is usually set inside the fish's body, and a swinging fork arm is connected to it to achieve the drive transmission of the fish's tail. The fork arm end is usually assembled to the housing of the swinging mechanism through a swinging connection to form a complete power transmission path.

[0003] However, the arrangement of this swing connection structure in the existing technology has certain defects: the assembly sections of the shell and the swing fork are mostly located on the same side (such as uniformly on the left or right side), and the decorative lines are also concentrated on one side. When the toy fish is accidentally dropped during use, especially when subjected to lateral impact, stress concentration is likely to occur in the concentrated force area, which may lead to breakage at the assembly position, affecting the normal use and lifespan of the toy. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, the embodiments of this utility model propose a swing mechanism that optimizes the assembly interface layout by arranging staggered lines, which not only improves the aesthetics and assembly accuracy, but also effectively disperses impact loads and enhances the impact resistance and structural stability of the swing mechanism.

[0005] This utility model embodiment also proposes a simulation toy having the above-mentioned swinging mechanism.

[0006] The technical solution adopted by this utility model is: to provide a swing mechanism, including a housing, a swing fork arm and a motor, wherein the motor is installed in the housing, one end of the swing fork arm is rotatably connected to the housing, and the motor is used to drive the swing fork arm to swing relative to the housing;

[0007] The housing includes an upper shell and a lower cover. The swing fork arm includes a first clamping arm and a second clamping arm. The upper shell and the lower cover are connected by a first decorative line. A second decorative line is provided between the first clamping arm and the second clamping arm, and the first decorative line and the second decorative line are staggered from each other in the vertical direction.

[0008] With the above structure, the assembly interface between the swing fork and the housing is no longer concentrated on one side of the toy fish, but is distributed through staggered first decorative lines, making the overall structure more visually balanced and aesthetically pleasing. Simultaneously, the staggered arrangement of the first and second decorative lines in the vertical direction effectively reduces localized stress concentration caused by external impacts. Specifically, when the toy fish accidentally falls or suffers a lateral impact during use, the force transmission path will be dispersed in multiple directions, thereby improving the overall impact resistance of the swing mechanism.

[0009] Furthermore, this structure offers significant advantages in assembly processes. The upper shell and lower cover are precisely fitted together using precision seams, which not only improves the structure's sealing performance but also facilitates later maintenance and component replacement. The second precision seam between the first and second clamping arms provides a precise reference for the symmetrical arrangement of the fork arms, resulting in more stable drive motion and reducing jamming or swaying issues caused by machining errors.

[0010] According to one embodiment of this utility model, the tail of the swing fork arm is provided with several deformation grooves, which divide the tail into multiple relatively deformable segments; thereby giving the fish tail a higher flexibility and deformation capability during the swinging process, making its movement posture closer to the swinging trajectory of the tail fin of a real fish. Each segment can produce a small relative displacement under the driving action, forming a natural and smooth swinging curve through overall linkage, further enhancing the simulation effect and ornamental value.

[0011] According to one embodiment of the present invention, the motor drives the swing fork arm to swing relative to the housing via a gear set.

[0012] According to one embodiment of this utility model, the gear set includes a face gear, a first gear, and a second gear. The face gear meshes with a gear mounted on the output shaft of the motor. The second gear is connected to the face gear via the first gear, forming a multi-stage transmission system. This structure transmits power through precise gear meshing, ensuring the smoothness of the motor drive and the precise control of the swing fork. Simultaneously, due to the design of the gear set, the entire drive system can maintain efficient operation under different loads, improving the system's stability and durability.

[0013] According to one embodiment of the present invention, the second gear is provided with a square shaft, the two ends of which extend out of the housing and are connected to the swing fork arm; the stable connection between the square shaft and the swing fork arm ensures reliable power transmission.

[0014] According to one embodiment of the present invention, the first clamping arm and the second clamping arm are combined to form a fork arm portion, and the first clamping arm or the second clamping arm is provided with a tail portion.

[0015] According to one embodiment of the present invention, the first clamping arm and the second clamping arm are respectively provided with square holes that cooperate with the square shaft.

[0016] According to one embodiment of the present invention, a battery and a motherboard are installed inside the housing.

[0017] According to one embodiment of the present invention, at least one of the upper shell, lower cover, first clamping arm, or second clamping arm is made of a plastic material containing catnip fragrance; the catnip fragrance can be achieved by mixing catnip extract with thermoplastic material during injection molding, and the resulting finished product can slowly release the odor at room temperature, with good volatility persistence and irritation, further enhancing its attractiveness to cats and improving the practicality and interactivity of the device.

[0018] According to one embodiment of the present invention, the upper shell or lower cover is provided with a charging port, through which the charging interface on the motherboard connects to an external charging device, providing a convenient charging method for the toy fish; and / or

[0019] The upper shell or lower cover is provided with a switch port.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0037] like Figure 1-7 As shown, this embodiment discloses a swing mechanism, including a housing 1, a swing fork arm 2 and a motor 3. The motor 3 is installed inside the housing 1, and one end of the swing fork arm 2 is rotatably connected to the housing 1. The motor 3 is used to drive the swing fork arm 2 to swing relative to the housing 1.

[0038] The housing 1 includes an upper shell 11 and a lower cover 12. The swing fork arm 2 includes a first clamping arm 21 and a second clamping arm 22. The upper shell 11 and the lower cover 12 are connected by a first decorative line 7. A second decorative line 8 is provided between the first clamping arm 21 and the second clamping arm 22, and the first decorative line 7 and the second decorative line 8 are staggered from each other in the vertical direction.

[0039] Furthermore, combined Figures 1 to 3As shown, a pivot structure is provided on one side of the housing 1, and the fork arm 23 of the swing fork arm 2 is located outside the pivot structure. The swing fork arm 2 reciprocates relative to the housing 1 around a preset axis. This reciprocating swing motion is achieved by a motor 3 mounted on the main board 5, which is driven alternately by the forward and reverse rotation of its output shaft. For ease of description, the direction of the preset axis is defined as the vertical direction.

[0040] Structurally, the housing 1 consists of an upper shell 11 and a lower cover 12. The lower cover 12 covers the opening at the lower end of the upper shell 11 and together with the upper shell 11, forms a closed internal space. Various electrical components, such as the motor 3, mainboard 5, and battery 4, are arranged and installed within this sealed space to ensure they are not affected by the external environment during operation, thus improving the stability and safety of the entire machine. One end of the swing fork arm 2 is designated as the fork arm portion 23, and the other end as the tail portion 24. The fork arm portion 23 has a first clamping arm 21 and a second clamping arm 22, with the tail portion 24 integrated with the second clamping arm 22. To facilitate the connection between the fork arm portion 23 and the pivot structure during assembly, the fork arm portion 23 has a square shaft hole 64 for mating. In terms of appearance design, the first decorative line 7 is located on one side in the vertical direction, while the second decorative line 8 is located on the opposite side in the vertical direction.

[0041] To elaborate further, in conjunction with Figure 5 As shown, the tail portion 24 of the swing fork arm 2 is provided with several deformation grooves 24a for assisting deformation. These deformation grooves 24a divide the tail portion 24 into multiple segments that can deform relative to each other. In this embodiment, the tail portion 24 has only one deformation groove 24a, which divides the tail portion 24 into two segments that can fold or deform relative to each other. The tail portion 24 can achieve periodic reciprocating deformation around the deformation groove 24a as a folding point. As an optional embodiment, in other design schemes, the tail portion 24 can also be provided with three or four deformation grooves 24a, thereby dividing the tail portion 24 into four or five segments, each segment having a certain relative deformation capacity to adapt to different motion requirements and structural elasticity.

[0042] More in detail, such as Figure 7As shown, the motor 3 drives the swing fork arm 2 to perform a periodic reciprocating swing motion around the housing 1 through a set of gears 6. The gear set 6 consists of an end face gear 61, a first gear 62, and a second gear 63 in sequence. The end face gear 61 directly meshes with a small gear fixedly mounted on the output shaft of the motor 3. The first gear 62 forms an intermediate transmission with the end face gear 61, and the second gear 63 forms a power connection with the end face gear 61 through the first gear 62, thus forming a multi-stage transmission gear system. A square shaft 64 is located at the center of the second gear 63. Both ends of the square shaft 64 extend through the two sides of the housing 1 and are connected to the left and right swing fork arms 2 respectively. To ensure installation stability and transmission reliability, square holes 23a that match the shape and size of the square shaft 64 are respectively provided on the first clamping arm 21 and the second clamping arm 22, thereby achieving a tight structural fit and synchronous power transmission.

[0043] Specifically, the upper shell 11 or the lower cover 12 is provided with a charging port 13, through which the charging interface on the motherboard 5 is connected to an external charging device, providing a convenient charging method for the toy fish; the upper shell 11 or the lower cover 12 is provided with a switch port 14, through which the hollow tube on the motherboard 5 is exposed, and the operation of the swing mechanism can be turned on or off by toggling the switch.

[0044] Furthermore, at least one of the upper shell 11, lower cover 12, first clamping arm 21, or second clamping arm 22 is made of a plastic material containing catnip fragrance. The catnip fragrance can be achieved by uniformly mixing catnip extract or microencapsulated catnip essential oil with a thermoplastic material (such as polypropylene, polyethylene, or thermoplastic elastomer) during injection molding. The mixing process can be carried out using a twin-screw extruder to prepare catnip fragrance masterbatch, followed by injection molding of the required parts using conventional injection molding equipment.

[0045] The catnip essential oil is processed using microencapsulation technology. The microcapsules consist of a polymer wall material (such as gelatin, polyurea, or cyclodextrin) encapsulating the catnip core substance, forming a stable encapsulation structure. This structure exhibits good thermal stability during injection molding, making it less prone to volatilization or degradation. In actual use, the microcapsule wall material gradually ruptures or permeates under the influence of external temperature, friction, or time, thus achieving a slow-release of the fragrance. This microcapsule release mechanism prolongs the fragrance duration while preventing the scent from becoming too strong, further enhancing its appeal to cats and improving the user experience.

[0046] In other embodiments, a simulation toy is disclosed, including the swing mechanism in this embodiment.
