[0022] 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 scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a decorative leg rest button with integrated sprue. (See also...) Figure 1 and Figure 3 A decorative element with an integrated water-cutting nozzle and a leg support button includes a decorative element body 1 and a leg support 9. The decorative element body 1 is composed of an arc-shaped rigid plate 5 and a flexible connector 2. The arc-shaped rigid plate 5 is composed of a textile layer 10, a soft pad 11, and a carbon fiber arc-shaped plate 12. The soft pad 11 is glued to the upper side of the carbon fiber arc-shaped plate 12 with adhesive. The textile layer 10 is glued to both sides of the soft pad 11 with adhesive. The flexible connector 2 is fixed to both sides of the leg support 9 by a fixing mechanism 3. A protective layer 4 is provided on the outer side of the decorative element body 1. An arc-shaped groove 18 is provided on the upper side of the leg support 9 corresponding to the lower side of the arc-shaped rigid plate 5. The leg support 9 is composed of an internal support frame 8, a silicone sponge pad 17, and a leather layer 19. The internal support frame 8 is installed inside the silicone sponge pad 17, and the leather layer 19 is wrapped around the outside of the silicone sponge pad 17.
[0025] Reference Figure 1 The fixing mechanism 3 consists of a male buckle 6 and a female buckle 7. The male buckle 6 is installed on both sides of the flexible connector 2, and the female buckle 7 is installed on both sides of the leg support 9. The male buckle 6 is fastened inside the female buckle 7. The fixing mechanism 3 adopts a snap-fit design of "male buckle 6 + female buckle 7", which realizes the quick connection and disassembly of the decorative part body 1 and the leg support 9 through mechanical fastening: When assembly is required, align the male buckle 6 with the female buckle 7 and apply slight pressure. The male buckle 6 can be embedded in the female buckle 7 to form a stable connection, ensuring that the flexible connector 2 drives the decorative part body 1 and the leg support 9 to fit tightly together, avoiding separation of the two due to vibration or force during use; When maintenance or replacement of parts is required, simply pull the flexible connector 2 or the leg support 9 outward, and the male buckle 6 can be released from the female buckle 7 without the need for tools. This not only improves assembly efficiency but also reduces the difficulty of later maintenance, while adapting to the convenience requirements of the integrated sprue structure.
[0026] Reference Figure 5The protective layer 4 consists of a fire-resistant layer 14, a self-cleaning layer 15, and a UV-resistant layer 16. The UV-resistant layer 16 is attached to the outside of the decorative component body 1, the self-cleaning layer 15 is attached to the outside of the UV-resistant layer 16, and the fire-resistant layer 14 is attached to the outside of the self-cleaning layer 15. The protective layer 4 adopts the configuration of "fire-resistant layer 14 + self-cleaning layer 15 + UV-resistant layer 16". The three-layer composite structure provides comprehensive protection for the decorative component body 1 through sequential attachment of each layer. The innermost UV-resistant layer 16 is directly attached to the outside of the decorative component body 1, absorbing external ultraviolet rays and preventing the material from aging, discoloring, or cracking due to long-term UV exposure, thus extending the service life of the component. The self-cleaning layer 15, with its special surface properties, reduces the adhesion of contaminants such as dust and oil. Even if a small amount of contaminants remain, they can be removed by simple wiping or rainwater rinsing, reducing the difficulty of daily cleaning and maintaining the clean appearance of the decorative component. The outermost fireproof layer 14 is attached to the outside of the self-cleaning layer 15. When exposed to open flames or high temperatures, it can inhibit the combustion reaction, prevent the flame from spreading into the interior of the decorative component body 1, avoid damage to the component due to combustion, reduce fire hazards, and ensure the safety of the decorative component in different usage environments. The three-layer structure works synergistically to protect the decorative component body 1 from three dimensions: anti-aging, easy cleaning, and fire resistance.
[0027] Reference Figure 5 The fireproof layer 14 is a flame-retardant acrylic coating layer. The fireproof layer 14 is a flame-retardant acrylic coating layer. The coating contains flame retardant components. When exposed to fire risks such as high temperature and open flame, the flame retardant will quickly undergo a chemical reaction. On the one hand, it can form a dense carbonized layer on the surface of the coating, blocking oxygen from contacting the decorative part body 1 and cutting off the oxygen supply required for combustion. On the other hand, it can absorb the heat generated by combustion, reduce the temperature of the decorative part body 1, and inhibit the continued combustion reaction, thereby playing a flame-retardant role, preventing the flame from burning the decorative part body 1, and reducing the generation of toxic fumes, and preventing soot from falling and causing damage to the decorative part body 1.
[0028] Reference Figure 5 The self-cleaning layer 15 is set as an organosilicon-modified self-cleaning coating layer. The organosilicon-modified self-cleaning coating layer selected for the self-cleaning layer 15 has a low surface energy molecular structure after organosilicon modification. This structure makes it difficult for pollutants such as dust, oil stains, and water stains to effectively adsorb onto the coating surface. The pollutants can be easily removed under gravity or slight external force. At the same time, the coating has good hydrophobicity. When rainwater washes over it, a water film can be formed on the surface, which carries away the small amount of pollutants attached to it, achieving a "self-cleaning" effect. There is no need for frequent manual deep cleaning. It can maintain the cleanliness and aesthetics of the outer side of the decorative part body 1 for a long time, and reduce the wear and tear on the coating and internal body structure during the cleaning process, thus extending the overall service life of the decorative part.
[0029] Reference Figure 5The UV-protective layer 16 is set as a UV-absorbing coating layer. The UV-protective layer 16 is a UV-absorbing coating layer that can selectively absorb ultraviolet rays from sunlight or the environment and convert the absorbed ultraviolet energy into low-energy heat energy or harmless fluorescent energy for release, thus preventing ultraviolet rays from directly acting on the decorative part body 1 material. Since the textile layer 10, soft pad 11, soft connector 2 and other components of the decorative part body 1 are mostly made of polymer materials, long-term exposure to ultraviolet rays can easily cause molecular chain breakage, leading to material aging, discoloration and decreased elasticity. The UV-absorbing coating layer can effectively block ultraviolet rays from penetrating and protect the molecular structure stability of the body material, thereby preventing the decorative part from aging, cracking and fading, and ensuring that the decorative part can maintain a good appearance and performance in long-term outdoor or strong light environments.
[0030] Reference Figure 4 A friction pad 13 is provided at the bottom end of the carbon fiber curved plate 12. The friction pad 13 is attached to the bottom end of the carbon fiber curved plate 12 with adhesive. The friction pad 13 is made of a material with a high coefficient of friction. After being attached to the bottom end of the carbon fiber curved plate 12, when the curved rigid plate 5 is in contact with the curved groove 18 on the leg support 9, the friction pad 13 can directly contact the inner wall of the groove. By increasing the friction between the two, it prevents the curved rigid plate 5 from sliding or shifting in the groove. Especially when the user operates the buttons of the leg support 9, adjusts the angle of the leg support 9, or places the legs, the curved rigid plate 5 will be subjected to a certain external force. The high friction of the friction pad 13 can counteract the sliding tendency caused by these external forces, ensuring the stability of the decorative part body 1 and not affecting the normal operation of the buttons of the leg support 9. At the same time, the friction pad 13 can also play a buffering role, reducing the collision and wear between the curved rigid plate 5 and the groove, extending the service life of both, and further improving the stability and durability of the decorative part.
[0031] Working Principle: In use, the decorative body 1 and leg rest 9 combine to achieve a balance between aesthetics and practicality. The curved rigid plate 5 of the decorative body 1 employs a composite structure of a textile layer 10, a soft pad 11, and a carbon fiber curved plate 12. The carbon fiber curved plate 12, with its high strength and lightweight characteristics, provides a stable support frame for the decorative body, ensuring it can adapt to the installation and usage scenarios of the leg rest 9 buttons, while preventing deformation due to stress from affecting button operation. The soft pad 11 is adhered to the upper side of the carbon fiber curved plate 12 with adhesive, providing cushioning when the user contacts it and improving leg comfort. The textile layer 10 is attached to both sides of the soft pad 11, enhancing its wear resistance and optimizing the user experience with its soft touch. The connector 2 is connected to both sides of the leg support 9 via the fixing mechanism 3, enabling flexible assembly of the decorative body 1 and the leg support 9. This ensures a stable connection without affecting the adjustment function of the leg support 9. The protective layer 4 on the outside of the decorative body 1 isolates dust, oil, and external impacts from the outside, protecting the internal structure from damage. The arc-shaped groove 18 on the upper side of the leg support 9 matches the shape of the lower part of the arc-shaped hard plate 5, allowing the decorative body 1 to precisely fit the leg support 9, preventing displacement during use and further improving structural stability. In addition, in the "internal support frame 8 + silicone sponge pad 17 + leather layer 19" structure of the leg support 9, the internal support frame 8 provides load-bearing support for the leg support 9, ensuring that the leg support 9 can withstand the weight of the legs without deformation. The silicone sponge pad 17 has good elasticity and can adapt to the shape of the legs, enhancing support comfort. The leather layer 19 wraps around the outside, improving the aesthetics of the leg support 9 and facilitating cleaning, meeting the practical needs of the decorative part.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
