Description

Technical Field

[0001] This utility model relates to the field of automotive flooring technology, and in particular to a waterproof and stain-resistant automotive flooring structure. Background Technology

[0002] Traditional automotive floor structures typically employ a one-piece or simple splicing design, resulting in insufficient waterproofing and stain resistance, easy accumulation of dirt, and difficulty in cleaning. While some floors feature anti-slip textures, they struggle to effectively absorb liquids, leaving water stains on shoe soles and potentially leading to odors or mold over time. Furthermore, the gaps between the floor and the vehicle's underbody allow dust, debris, and other small particles to easily seep in, creating hard-to-clean areas. Existing solutions largely rely on sealants or fasteners, but sealants are prone to aging and failure, while rigid fasteners lack cushioning, impacting comfort. A few high-end models utilize composite laminate structures, but these are costly and inconvenient to maintain. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waterproof and stain-resistant automotive floor structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a left main board, on one side of the top of the left main board two sets of dovetail grooves, each set of dovetail grooves is fitted with a dovetail block, and one end of each set of dovetail blocks is provided with a right main board, and the top of both the left and right main boards is provided with anti-slip strips.

[0005] Preferably, both the left and right motherboards have a polyurethane coating on their surfaces.

[0006] Preferably, a water-absorbing groove is provided on one side of the anti-slip strip, and a water-absorbing sponge is inserted into the inside of the water-absorbing groove.

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.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4A waterproof and stain-resistant car floor structure includes a left main board 1 and a right main board 4. The shape and size of the left main board 1 and the right main board 4 are consistent with the left and right sides of the rear seats of the car where floor mats need to be laid. For example, the left main board 1 can be consistent with the shape and size of the left side of the rear seats where floor mats need to be laid, and the right main board 2 can be consistent with the shape and size of the right side of the rear seats where floor mats need to be laid. The connection between the left main board 1 and the right main board 4 is consistent with the shape and size of the middle front part of the rear seats where floor mats need to be laid.

[0024] Two sets of dovetail grooves 2 are provided on the right side of the top of the left main board 1, and two sets of dovetail blocks 3 are provided on the left side of the top of the right main board 4. The dovetail blocks 3 are engaged inside the dovetail grooves 2. Friction exists between the dovetail blocks 3 and the dovetail grooves 2 during engagement, requiring a certain external force to engage and disengage them. During normal operation, external vibrations will not cause displacement of the contact surfaces between the dovetail blocks 3 and the dovetail grooves 2. Anti-slip strips 5 are provided on the top of both the left and right main boards 1 and 4. Both surfaces of the left and right main boards 1 and 4 are coated with a polyurethane coating, which is hydrophobic, preventing liquid penetration and facilitating cleaning. Water-absorbing grooves are provided on the right side of the left main board 1 and the left side of the right main board 4, with absorbent sponges 6 engaged inside. The absorbent sponges 6 effectively absorb water stains from the left and right main boards 1 and 4, ensuring the cleanliness of the main boards. A convenient slot 7 is provided on one side of the top of the water absorption tank. One side of the convenient slot 7 fits against one side of the water-absorbing sponge 6. If the water-absorbing sponge 6 is saturated or aged, it can be quickly removed and replaced through the convenient slot 7. The front and rear ends of the left main board 1 and the right main board 4 are both provided with grooves. An air cushion layer 8 is set inside the groove. The groove and the air cushion layer 8 have the same shape. The air cushion layer 8 is made of elastic TPU material, which has good pressure resistance and resilience. An air inlet 9 is provided on the top of the air cushion layer 8. A closing cover 10 is threaded to the top of the air inlet 9. The surface of the closing cover 10 is provided with a threaded strip, which makes it easy for the user to rotate the closing cover 10. The four sides of the surface of the left main board 1 and the right main board 4 are rounded to avoid sharp corners scratching the interior parts or passengers, and to reduce the possibility of dirt accumulation.

[0025] There are ten sets of anti-slip strips 5, and five sets of anti-slip strips 5 are respectively set on the top of the left main board 1 and the right main board 4 to increase the friction with the feet of passengers and improve anti-slip performance. The left main board 1 and the right main board 4 adopt a modular design to support the replacement of the left main board 1 or the right main board 4 individually, reducing maintenance costs. The left main board 1 and the right main board 4 are made of high-strength ABS plastic injection molding.

[0026] Reference Figure 4The surface of the air inlet 9 penetrates the inner wall of the motherboard, and the air inlet end of the air inlet 9 is located at the top of the motherboard. The air inlet 9 is connected to an external air pump. The air cushion layer 8 begins to expand and fill. After inflation is completed, the air inlet 9 is sealed by the closing cover 10. Specific Implementation Example 2:

[0028] A waterproof and stain-resistant car floor structure, further based on the basic structure in Specific Embodiment 1, comprises the following steps: First, the left main board 1 and the right main board 4 are assembled with the dovetail block 3 via the dovetail groove 2 to ensure the stability of the floor structure; next, water-absorbing sponge 6 is embedded in the water-absorbing groove of the anti-slip strip 5 to absorb moisture and stains; then, the air cushion layer 8 is inflated through the air inlet 9, so that it expands and fits tightly against the rear seat floor of the car to prevent small debris from entering the gaps; finally, the closing cover 10 is tightened to seal the air cushion layer 8, and the waterproof and stain-resistant performance of the overall structure is checked.

[0029] Its working principle is as follows: The floor structure utilizes the mechanical connection between dovetail grooves 2 and dovetail blocks 3 to achieve stable assembly. Anti-slip strips 5 and absorbent sponges 6 work together to enhance anti-slip performance and absorb liquid stains. The air cushion layer 8 expands after inflation, filling the gap between the floor and the vehicle body, forming a physical barrier to prevent dust and debris from penetrating. The polyurethane coating further enhances waterproof and stain-resistant capabilities, while the rounded corner design improves safety. The overall structure achieves highly efficient waterproof, stain-resistant, and shock-absorbing effects through modular design and air cushion layer 8.

[0030] In summary:

[0031] The system incorporates anti-slip strips 5, absorbent sponges 6, dovetail grooves 2, and dovetail blocks 3. The anti-slip strips 5 effectively enhance the friction of the floor surface, preventing passengers from slipping and improving driving safety. The absorbent sponges 6 quickly absorb moisture from shoe soles or spilled liquids inside the vehicle, keeping the floor dry and clean. The dovetail grooves 2 and dovetail blocks 3 work together to securely connect the left main board 1 and the right main board 4, facilitating disassembly and maintenance. Together, they achieve waterproof, stain-resistant, durable, and easy-to-clean properties, while also ensuring both passenger comfort and practicality.
