In addition, the present application provides examples of various specific processes and materials, but those skilled in the art will be able to recognize the application of other processes and / or the use of other materials. Furthermore, with the increasing popularity of AI-powered plush toys, there is a growing demand for products with superior features and more capabilities. This leads to increased heat generation from chips and other devices in order to improve functionality and power consumption. Due to the inherent thick packaging and completely sealed nature of plush toys, heat is not easily conducted within the movement case. As a result, overheating can not only cause the movement hardware to freeze, degrade in performance, or be damaged, but also pose a serious safety risk of burns to users (especially children) and even cause fires.

[0011] To solve the above problems, this invention provides a heat dissipation structure for plush toys having movement hardware. The "internal and external combination" of this invention constitutes an efficient heat management passage, effectively controlling the operating temperature of the movement hardware, preventing hardware damage and performance degradation due to overheating, thoroughly eliminating the risk of burns and fires to users, and significantly improving the safety and reliability of the product. Specifically, as shown in Figures 1 to 5, Figure 1 is a cross-sectional view of the overall structure of the present invention, Figure 2 is a schematic configuration diagram of the heat dissipation assembly and movement hardware of the present invention, Figure 3 is a schematic configuration diagram of the soft rubber cover of the present invention, Figure 4 is a schematic configuration diagram of the bore cover of the present invention, and Figure 5 is a schematic configuration diagram of the copper foil graphene heat dissipation sheet of the present invention.

[0012] The heat dissipation structure for a plush toy product having movement hardware according to an embodiment of the present application includes a movement case MC, a soft rubber cover 5, and a bore cover 6. The movement case MC includes a front movement case 1 and a rear movement case 2 that are detachably fixed together, and the front movement case 1 and the rear movement case 2 are joined by engaging hooks and engaging holes on their respective edges. Movement hardware 3 is provided inside the rear movement case 2. The movement hardware 3 of the present application is a circuit board on which a heat-generating device 31 is provided, and a heat dissipation assembly 4 for dissipating heat from the heat-generating device 31 is provided in the rear movement case 2. Multiple external interfaces and functional components are provided on the front movement case 1 and the rear movement case 2. The soft rubber cover 5 covers the outside of the movement case MC and has a first group of openings corresponding to the external interfaces and functional components. The bore cover 6 covers the outside of the soft rubber cover 5 and has a second group of openings corresponding to the first group of openings, and is formed by sewing with raised seams 7. The soft rubber cover 5 is provided with an inwardly recessed restricting passage 8 corresponding to the path of the raised seams 7, and the raised seams 7 are fitted into the restricting passage 8, thereby preventing the raised seams 7 from forming protrusions or indentations on the bore surface, ensuring the flatness and beauty of the product's appearance, as well as improving its feel.

[0013] In this embodiment, the heat dissipation assembly 4 includes a silicone rubber heat dissipation sheet 41, a metal heat dissipation bracket 42, and a copper foil graphene heat dissipation sheet 43. The metal heat dissipation bracket 42 is fixed inside the rear movement case 2. One side of the silicone rubber heat dissipation sheet 41 along its thickness direction is fixedly connected to the metal heat dissipation bracket 42, and the side along its thickness direction away from the metal heat dissipation bracket 42 is in close contact with the heat generating device 31. The shape of the inner surface of the copper foil graphene heat dissipation sheet 43 conforms to the curvature of the outer surface of the rear movement case, and the inner surface of the copper foil graphene heat dissipation sheet 43 and the outer surface of the rear movement case 2 are in close contact with each other by a fixing member. Adhesive is applied to one side of the copper foil graphene heat dissipation sheet 43, and by processing several notches and holes, it is possible to better adhere to irregularly shaped surfaces such as arcs, achieving a higher heat dissipation effect and a smoother appearance. In this embodiment, the external interface and functional components include one or more of the following: a display, a charging port, a speaker, and control buttons, and the control buttons include volume control buttons, replacement buttons, and switch buttons. External interfaces and functional components include, but are not limited to, displays, charging ports, speakers, and control buttons. They may also include USB interfaces, heat dissipation vents, etc., and any commonly used interfaces or components may be provided according to market needs.

[0014] In this embodiment, the cross-sectional shape of the restricting passage 8 conforms to the raised shape of the raised seam 7. In this embodiment, the raised seam 7 protrudes inward relative to the inner surface of the boa cover 6 and is fitted into the restricting passage 8, ensuring that the outer surface of the boa cover 6 is kept as flat as possible. In this embodiment, the soft rubber cover 5 is provided with a plurality of mesh-like through holes and / or non-through grooves (hereinafter referred to as mesh-like through holes and non-through grooves) 5a. The mesh-like through holes and non-through grooves 5a help to achieve a larger compression stroke and better rebound feel in the thinnest possible space, while also achieving weight reduction and heat dissipation, improving airflow, and helping to dissipate the heat accumulated between the soft rubber cover 5 and the bore cover 6, thereby assisting in heat dissipation. In this embodiment, the soft rubber cover 5 is liquid silicone rubber. Compared to solid high-temperature vulcanized silicone rubber, liquid silicone rubber is a liquid rubber with high fluidity, faster vulcanization, and is safer and more environmentally friendly. Liquid silicone rubber also has excellent tear resistance, resilience, yellowing resistance, thermal stability, heat resistance, and aging resistance.

[0015] When installing, first, the front movement case 1 and the rear movement case 2 are joined together using the engaging hooks and engaging holes on their respective edges to form the movement case MC. Next, the entire soft rubber cover 2 is placed over the movement case, ensuring that all interfaces are exposed. Furthermore, the bore cover 6 is placed over the outside of the soft rubber cover 5 from one end, and during the process, the raised seam 7 inside the bore cover 6 is manually aligned and fitted into the already aligned restrictive passage 8 in the soft rubber cover 5. As the bore cover 6 is pushed in, the raised seam 7 slides along the restrictive passage 8, continuing until the bore cover 6 is fully positioned and all openings are aligned. In this case, the raised seam 7 is completely hidden and, when touched from the outside, is smooth and flat, eliminating any negative impact of the internal structure on the appearance and ensuring a high-quality appearance and feel of the product. Inside the rear movement case 2, movement hardware 3 is provided. On the movement hardware 3, a heat generating device 31 is provided. In the rear movement case 2, a heat dissipation assembly 4 for dissipating the heat of the heat generating device 31 is provided. Such an "internal and external combination" of the heat dissipation assembly 4 constitutes an efficient heat management path, effectively controls the operating temperature of the movement hardware 3, prevents damage to the hardware and performance degradation due to overheating, thoroughly eliminates the risk of burns and fires to the user, and can greatly improve the safety and reliability of the product. The heat dissipation assembly 4 has a three-stage heat conduction or heat dissipation path, specifically as follows.

[0016] In the first stage (contact heat conduction), the silicone rubber heat dissipation sheet 41 is in direct contact with the heat generating device 31 and absorbs heat. The silicone rubber has high thermal conductivity and flexibility and can ensure adhesion. In the second stage (structural heat conduction), heat is conducted from the silicone rubber heat dissipation sheet 41 to the metal heat dissipation bracket 42, and the high thermal conductivity of the metal is used to diffuse the heat horizontally. In the third stage (heat dissipation to the outside), the copper foil graphene heat dissipation sheet 43 is in contact with the outer surface of the rear movement case 2. Graphene is the highest level of heat conduction material and can efficiently conduct the heat conducted from the metal heat dissipation bracket 42 to the entire rear movement case, increasing the heat dissipation area, and finally dissipating the heat into the air by the rear movement case 2.

Therefore, in all respects, the embodiments should be considered exemplary and non-limiting, and the scope of the present invention is limited not by the above description but by the attached utility model claims, so all modifications within the meaning and scope equivalent to the utility model claims are intended to be included in the present invention.
