[0019] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0020] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0021] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0022] A waterproof picnic mat for outdoor recreation, such as Figures 1 to 7 As shown, it is suitable for various outdoor environments, such as grass, sand, and mud, and has good waterproof, anti-slip, stability and portability.

[0023] like Figure 1 and Figure 2 As shown, the waterproof picnic mat for outdoor leisure of this utility model mainly includes a picnic mat body 1, which adopts a multi-layer composite structure, including, from bottom to top, a bottom anti-slip layer 101, a support layer 102, an activated carbon layer 103, a cushioning layer 104, a protective layer 105, and a surface layer 106. The layers are bonded together by environmentally friendly adhesives or hot-pressing processes to form a mat body with strong integrity and clearly defined functions.

[0024] like Figure 3 As shown, the lower surface of the bottom anti-slip layer 101 is provided with multiple biomimetic papillae structures. Each biomimetic papillae structure consists of a frustum 8 and a hemisphere 7 located at the top of the frustum 8. The bottom of the frustum 8 is fixedly connected to the bottom of the anti-slip layer 101. This structure mimics the attachment mechanism of organisms in nature (such as gecko paws), enabling multi-point contact on uneven surfaces such as sand and grass, significantly increasing friction and preventing the mat from sliding. The material used is high-density TPU (thermoplastic polyurethane), which combines flexibility and wear resistance, adapting to various terrains. The biomimetic papillae structures are molded using a micro-injection molding process, with a distribution density of 15-20 per square centimeter, ensuring excellent anti-slip performance even on wet and slippery surfaces.

[0025] like Figure 5 and Figure 6 As shown, the support layer 102 adopts a modular assembly structure, consisting of two long plates 1021 and two short plates 1022 fixed together by connectors 11. The interiors of the long plates 1021 and short plates 1022 have a hollow structure, which reduces the overall weight while maintaining sufficient support strength. The connecting surfaces are angled and equipped with slide rails for easy assembly and disassembly.

[0026] The long plate 1021 and the short plate 1022 are made of lightweight ABS engineering plastic with a moisture-proof coating to prevent deformation due to moisture. A sliding plate 13 is slidably connected to the slide rail, with the end of the sliding plate 13 welded to the side wall of the connector 11 to ensure a stable connection. A connecting groove is provided at the top, within which a connecting plate 1023 and a fixing plate 1024 are fixed. The fixing plate 1024 connects to the fixing groove at the top of the connecting plate 1023, forming a self-locking structure and enhancing overall rigidity.

[0027] The bottom anti-slip layer 101 and the support layer 102 are connected by a detachable connection structure. In this embodiment, the structure is a hook and loop fastener connection structure, including a hook and loop fastener rough surface 12 on the bottom anti-slip layer 101 and a hook and loop fastener hook surface on the bottom of the support layer 102. The hook and loop fastener is made of high-strength nylon material, which is tear-resistant, water-resistant, and reusable. It is designed for segmented adhesion, which facilitates partial replacement or cleaning and reduces maintenance costs.

[0028] like Figure 1 As shown, the picnic mat body 1 has quick-fix components at its four corners, including connecting pieces 4, extension plates 3, fixing pieces 6, and ground stakes 5. In use, the ground stakes 5 are driven into the ground through the fixing pieces 6 and connected to the mat body via the extension plates 3 and connecting pieces 4, achieving quick anchoring. The ground stakes 5 are made of stainless steel with an anti-corrosion treatment, suitable for damp soil. The connecting pieces 4 are connected to the mat body with reinforced stitching to ensure they do not easily fall off in strong winds.

[0029] The activated carbon layer 103, located above the support layer 102, is made of activated carbon fiber composite material and has moisture-absorbing, mildew-proof, and odor-absorbing functions, keeping the inside of the mat dry and hygienic. The cushioning layer 104 is a multi-layered composite sponge structure using high-elasticity memory foam, 2-3cm thick, effectively absorbing impact and providing a comfortable sitting or lying experience. The protective layer 105, such as... Figure 4 As shown, a silicone strip 9 and a guide strip 10 are fixed at the top. The silicone strip 9 serves to prevent slipping and prevent water penetration, while the guide strip 10 facilitates the placement and positioning of items. The surface layer 106 is made of pure cotton fleece material, treated with a nano-level waterproof coating, which is soft to the touch and has excellent waterproof performance, is easy to clean, and dries quickly.

[0030] The picnic mat body 1 features adjustable straps 2 along both sides, using nylon webbing and plastic buckles for easy rolling and carrying, enhancing portability. After use, the surface 106 should be cleaned promptly to prevent stain accumulation. If a part is damaged (such as the Velcro or straps), it can be replaced individually; the entire mat does not need to be discarded. Before long-term storage, ensure all parts are dry and avoid direct sunlight.

[0031] The picnic mat body 1, the ground pegs 5, and the Velcro are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0032] Working principle This waterproof picnic mat for outdoor recreation, when used, firstly, when the picnic mat body 1 is laid on the ground, the biomimetic nipple structure on the lower surface of the bottom anti-slip layer 101, composed of a frustum 8 and a hemisphere 7, forms multiple points of contact with the ground, mimicking the principle of biological adhesion mechanics, significantly increasing friction and preventing the picnic mat body 1 from sliding on wet or uneven surfaces such as grass or sand. Simultaneously, the quick-fix components at the four corners of the picnic mat body 1 are driven into the ground via ground stakes 5, and mechanically anchored with connecting pieces 4 and fixing pieces 6, maintaining the stability of the mat even in strong winds or on sloping terrain.

[0033] Secondly, the support layer 102 adopts a modular assembly structure, which is quickly assembled from long plates 1021 and short plates 1022 via connectors 11 and slide rails. The internal hollow design reduces the overall weight, while the inclined connecting surfaces and self-locking structure (connecting plate 1023 and fixing plate 1024) enhance the overall rigidity. The support layer 102 is connected to the bottom anti-slip layer 101 via Velcro, which facilitates disassembly and replacement, meeting the needs of portability and storage.

[0034] Furthermore, the cushioning layer 104 employs a multi-layer composite sponge structure to effectively absorb impact and vibration, providing a soft sitting or lying experience. The activated carbon layer 103 has moisture-absorbing, mildew-proof, and odor-absorbing functions, keeping the inside of the picnic mat body 1 dry and hygienic. The silicone strip 9 and guide strip 10 on the top of the protective layer 105 enhance the surface's abrasion resistance and water resistance, while the surface layer 106 is made of pure cotton fleece material, which is comfortable to the touch and easy to clean.

[0035] Finally, the picnic mat body 1 can be quickly rolled up and carried using the adjustable straps 2 on both sides. After use, the surface 106 is easy to clean, and locally damaged components (such as Velcro or straps 2) can be replaced individually, extending the product's lifespan.
