[0020] 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.

[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 and Figure 2 As shown, a multi-layer composite heating film for drones or model aircraft includes a heating film 1, an insulating layer 2 on top of the heating film 1, and a protective layer 3 on the other side of the insulating layer 2. The insulating layer 2 has several evenly distributed heating elements 4 that penetrate it. Grooves 5 corresponding to the heating elements 4 are provided on the side of the heating film 1 and the protective layer 3 closest to the insulating layer 2. Furthermore, an adhesive layer 6 is laid on the side of the heating film 1 away from the insulating layer 2 and inside the grooves 5 to enhance the adhesion of the heating film to the surface of the drone or model aircraft.

[0024] In this embodiment, the heating element 4 is made of high-performance conductive material, ensuring heating efficiency and stability. Simultaneously, the thickness of the heating element 4 is carefully designed to be greater than the thickness of the insulation layer 2, thus guaranteeing not only the mechanical strength of the heating element 4 but also contributing to the overall durability of the heating film 1. The protective layer 3 is made of a soft silicone layer, a material with good flexibility and heat resistance, capable of protecting the heating element 4 from damage in various environments. Furthermore, the outer surface of the protective layer 3 has several evenly distributed protrusions 7, forming water-guiding grooves between these protrusions 7, facilitating rapid drainage in humid environments and further protecting the heating film 1 from moisture erosion. To further improve the heating uniformity of the heating film 1, the heating elements 4 are electrically connected to form a uniform current distribution, ensuring consistent heating performance across the entire heating film 1. The adhesive layer 6 is selected considering the different materials of the drone or model aircraft surface, ensuring that the heating film 1 can firmly adhere to various surfaces, maintaining stability during high-speed flight or complex maneuvers.

[0025] like Figure 3 and Figure 4As shown, the heating elements 4 are electrically connected, and the thickness of the heating elements 4 is greater than the thickness of the insulating layer 2 to ensure heating effect. Several evenly distributed protrusions 7 are provided on the outer surface of the protective layer 3, forming water-guiding grooves between the protrusions 7, which facilitates drainage and protects the heating film. The heating film 1 contains a metal foil, the insulating layer 2 is made of polymer material, and the protective layer 3 is a soft silicone layer. These materials are chosen to provide good thermal conductivity, insulation, and durability.

[0026] In this embodiment, the electrical connection of the heating element 4 is achieved through precise circuit design, ensuring that current flows evenly through each heating element, thereby generating a uniform heat distribution across the entire heating film 1. This design avoids heat concentration in certain areas, reducing the risk of localized overheating and improving heating efficiency. The protruding rod 7 not only aids in drainage but also increases the mechanical strength of the protective layer 3 to a certain extent, making it more resistant to wear and impact. The water channel design allows moisture to drain quickly from the surface of the heating film in rainy or humid environments, reducing the impact of moisture on the performance of the heating film. The metal foil placed inside the heating film 1 provides an efficient heat conduction path, further enhancing the heating performance of the heating film. The insulating layer 2, made of polymer material, not only has good insulation properties but also sufficient flexibility to adapt to the surfaces of drones or model aircraft of different shapes. The silicone soft layer, as the protective layer 3, provides physical protection and also has good temperature and weather resistance, ensuring stable performance even under extreme temperature changes. Furthermore, the addition of adhesive layer 6 ensures that the heating film 1 can firmly adhere to the surface of the drone or model aircraft, maintaining stability even during high-speed flight or violent maneuvers, without displacement or detachment. This multi-layered composite structure design comprehensively considers the heating uniformity, durability, insulation, and adhesion of the heating film, providing strong support for the stable operation of drones or model aircraft in various environments.

[0027] In use, the heating film 1 serves as the core heating element. The insulating layer 2 above it not only provides necessary electrical isolation but also acts as a carrier for the heating elements 4, ensuring their uniform distribution. These heating elements 4 are made of high-performance conductive materials and are thicker than the insulating layer 2 to enhance mechanical strength and improve durability. The electrical connections between the heating elements 4 are achieved through a precise circuit design, ensuring uniform current distribution and generating uniform heat across the entire heating film 1, avoiding localized overheating and improving heating efficiency. The protective layer 3 is composed of a soft silicone layer with good flexibility and heat resistance, protecting the heating elements 4 from physical damage. The protruding rods 7 and water-guiding grooves on its outer surface facilitate rapid drainage in humid environments, reducing the impact of moisture on the heating film's performance. The metal foil within the heating film 1 provides an efficient heat conduction path, further enhancing heating performance. The insulating layer 2 is made of polymer materials with excellent insulation properties and flexibility, adapting to the surfaces of drones or model aircraft of different shapes. The adhesive layer 6 ensures that the heating film 1 adheres firmly to the surface of the drone or model aircraft, maintaining stability even during high-speed flight or complex maneuvers.

[0028] This multi-layered composite structure design comprehensively considers the heating uniformity, durability, insulation, and adhesion of the heating film, providing strong support for the stable operation of drones or model aircraft in various environments. It ensures the temperature of the battery and key components in low-temperature environments, thereby guaranteeing flight performance and equipment safety.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
