[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5 A modular protective floor for a trunk includes a fixed plate 1, which is designed in this embodiment to be convex to fit the shape of most trunks. The fixed plate 1 has an internal placement groove 2, with a limiting frame 3 at the bottom. A groove 4 is provided on one side of the top of the fixed plate 1, facilitating the user to lift and separate the protective plate 8 from the fixed plate 1. A support plate 5 is provided on the top of the limiting frame 3, and the surface of the support plate 5 is coated with a waterproof layer. A first zipper strip 6 is provided along the perimeter of the top of the support plate 5, a second zipper strip 7 is provided on the top of the first zipper strip 6, and the protective plate 8 is provided on the top of the second zipper strip 7. The interior of the protective plate 8 is filled with a sponge layer. The first zipper 6, the second zipper 7, and the protective plate 8 are all located inside the placement groove 2. One side of the protective plate 8 is attached to one side of the groove 4. The top of the support plate 5 is provided with four sets of water channels 9, and all four sets of water channels 9 penetrate through the interior of the support plate 5. The bottom of the support plate 5 is provided with four sets of limiting strips 10. One end of each of the four sets of limiting strips 10 is provided with a limiting groove 11. The interior of two sets of limiting grooves 11 is provided with a collection box 12. The top of the collection box 12 is provided with a flow channel.

[0026] Reference Figure 3-4 Each pair of water troughs 9 has a collection box 12 at its bottom. The interior of the water troughs 9 is concave to facilitate liquid flow, and the flow channels are designed to collect water that falls into the water troughs 9, and also facilitate the quick emptying of the liquid collected in the collection box 12. The protective plates 8 are connected layer by layer by the first zipper 6 and the second zipper 7, allowing the protective plates 8 to be quickly removed for easy cleaning and to ensure the cleanliness of the trunk interior. Specific Implementation Example 2:

[0028] A trunk-mounted modular protective floor, further based on the basic structure in Specific Embodiment 1, comprises the following steps: First, a fixing plate 1 is installed at the bottom of the trunk, ensuring the placement groove 2 is fixed to the limiting frame 3. Next, a support plate 5 is embedded into the limiting frame 3, ensuring a secure fit, and protective plates 8 are connected layer by layer via a first zipper 6 and a second zipper 7 to form a detachable protective structure. Subsequently, a waterproof layer with a drainage channel 9 is installed on the top of the support plate 5, and a collection box 12 is pushed in along the limiting slide 11, ensuring it is aligned with the drainage channel 9 to collect liquid. Due to friction during the connection between the collection box 12 and the limiting slide 11, a certain external force needs to be applied to the collection box 12 to separate and connect it. During daily use, external vibrations will not cause the collection box 12 and the limiting slide 11 to detach. Finally, check whether each component is securely fixed, ensuring the protective plate 8 fits tightly with the groove 4, completing the assembly.

[0029] Its working principle is as follows: the combination of the limiting frame 3 and the support plate 5 provides a stable load-bearing foundation, while the flexible connection of the zipper strip realizes a modular protective structure, which is easy to adjust and replace. The waterproof coating and the drainage channel 9 work together to guide the liquid flow to the collection box 12, avoiding water accumulation and corrosion. The sponge layer inside the protective plate 8 absorbs vibration and impact, reducing the risk of damage to items. This enhances the protective performance, facilitates cleaning and maintenance, and improves the practicality and durability of the trunk space.

[0030] In summary:

[0031] The system employs a combination of a protective plate 8, a drainage channel 9, a limiting strip 10, and a collection box 12. The protective plate 8 effectively absorbs impact and protects items from collision damage. Simultaneously, the internal sponge layer enhances cushioning performance. When liquid leaks from the cargo in the trunk, the sponge layer absorbs the moisture and drips excess liquid into the drainage channel 9. The drainage channel 9 guides the liquid flow, preventing water accumulation that could corrode the floor or contaminate items. The limiting strip 10 and collection box 12 work together to collect liquids, facilitating cleaning and maintenance. The waterproof coating design enhances water resistance and durability, thus achieving both protection and convenient maintenance.

[0032] The system employs a first zipper 6, a second zipper 7, a limiting frame 3, and a support plate 5. The cooperation between the first zipper 6 and the second zipper 7 facilitates flexible assembly and disassembly of the support plate 5 and the protective plate 8. The limiting frame 3 ensures precise positioning of the support plate 5, preventing displacement or loosening and improving overall stability. As the main load-bearing structure, the support plate 5, combined with a waterproof coating, not only enhances durability but also effectively prevents liquid penetration, extending its service life.
