Description

Technical Field

[0001] This utility model relates to the field of automotive interior accessories technology, specifically a multi-layer composite automotive floor mat structure. Background Technology

[0002] Car floor mats are environmentally friendly car interior components that integrate functions such as water absorption, dust absorption, and sound insulation. Their multi-layer composite structure combines the advantages of different materials: the surface layer is wear-resistant, stain-resistant, and easy to clean; the middle layer provides cushioning, shock absorption, sound insulation, and noise reduction; and the bottom layer is anti-slip, fixed, and prevents displacement. They are fully adaptable to various car interior usage scenarios, solving the functional shortcomings of single materials.

[0003] Existing car floor mats generally suffer from cumbersome assembly processes, insufficient connection stability, and a single fixing structure that makes them prone to displacement during driving due to stepping or vibration, interfering with pedal operation and threatening driving safety. The assembly and disassembly processes are complicated, and maintenance requires overall cleaning, which is not only inefficient but also prone to component aging and damage, increasing usage costs. It is difficult to balance cleanliness and protection with usage stability, and the driving and riding environment is not comfortable, failing to meet users' needs for multifunctional and highly reliable floor mats.

[0004] To address this, we propose a multi-layer composite car floor mat structure that allows for multiple locking installations, individual cleaning and replacement of components, reduced maintenance costs, and prevents displacement while ensuring safety. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the single fixed structure makes the vehicle prone to displacement due to stepping or vibration during driving, which interferes with pedal operation and threatens driving safety. The assembly and disassembly process is cumbersome, and maintenance requires overall cleaning, which is not only inefficient but also prone to component aging and damage, increasing the cost of use and making it difficult to balance cleanliness and stability in use.

[0006] To solve the above-mentioned technical problems, this application provides a multi-layer composite car floor mat structure, including an anti-slip fixing layer. The anti-slip fixing layer has four elastic wrapping edges on its outer side, and the inner side of the elastic wrapping edges has a Velcro surface. The top of the anti-slip fixing layer has three positioning grooves and four positioning protrusions. The top groove of each positioning protrusion has a snap fastener seat.

[0007] In some embodiments, an intermediate filter water-absorbing layer is slidably connected to the outside of the four positioning protrusions, and three magnetic blocks are provided at the bottom of the intermediate filter water-absorbing layer. The bottom of the magnetic blocks is magnetically attached to the top of the magnetic sheet at the bottom of the inner side of the positioning groove.

[0008] In some embodiments, the outer side of the intermediate filter absorbent layer is provided with four guide grooves, the inner side of which is slidably connected to the outer side of the positioning protrusion. The intermediate filter absorbent layer includes an upper activated carbon filter layer, a middle super absorbent resin water storage layer, and a lower breathable isolation mesh.

[0009] In some embodiments, the snap-on sub-seat is externally engaged with a snap-on female seat, and the snap-on female seat is externally slidably connected in the top groove of the positioning protrusion.

[0010] In some embodiments, the top of the four snap-fit ​​female seats is provided with a surface functional layer, and the top of the surface functional layer is provided with a plurality of anti-slip protrusions.

[0011] In some embodiments, the four anti-slip protrusions are provided with inverted conical dust suction holes on their horizontally similar sides, and the exterior of the plurality of inverted conical dust suction holes is opened on the top of the surface functional layer.

[0012] In some embodiments, a removable non-woven filter is fitted into a filter mounting groove at the bottom of the surface functional layer, and an annular sealing edge is provided at the top of the surface functional layer, with a Velcro hook surface at the top of the annular sealing edge.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. The three-layer structure is initially fixed by the precise guidance of the guide groove and positioning protrusion, and magnetic adsorption. It is further secured by the double locking of the buckle and Velcro. The assembly is convenient and the connection is firm. No tools are required for disassembly. The surface functional layer, the middle water-absorbing filter layer and the non-woven filter can be removed separately for cleaning and replacement, avoiding damage to the parts caused by overall cleaning and reducing maintenance costs. At the same time, the multiple fixing structure effectively prevents the floor mat from shifting and ensures driving safety.

[0015] 2. It has a significant water absorption and dust prevention effect. The surface anti-slip protrusions achieve diversion and anti-slip. The inverted cone-shaped dust suction holes, together with the non-woven fabric filter, intercept dust in stages to prevent it from scattering and seeping. After water stains are purified by the activated carbon filter layer, the highly absorbent resin water storage layer effectively locks in the water to prevent it from seeping into the car's main carpet. In addition, the foamed rubber base material and anti-slip structure enhance the bottom friction, and the elastic wrapping edge limits the movement, taking into account both cleanliness and stability of use, and improving the comfort of the driving environment.

[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 protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 4 and Figure 5 This utility model provides a technical solution: a multi-layer composite car floor mat structure, including an anti-slip fixing layer 1. The anti-slip fixing layer 1 is made of high-density foamed rubber material, which has excellent elastic deformation ability and wear resistance. The outer side of the anti-slip fixing layer 1 is provided with four elastic wrapping edges 2. The four elastic wrapping edges 2 are distributed in a rectangular shape, corresponding to the four edges of the car floor mat, and can closely fit the contour of the car floor. The inner side of the elastic wrapping edges 2 is provided with a Velcro surface 3. The Velcro surface 3 has a fine fiber structure, high bonding strength, and is not easy to shed after repeated application. The top of the anti-slip fixing layer 1 is provided with three positioning grooves 18. The three positioning grooves 18 are evenly arranged in a triangle, and the groove depth is adapted to the thickness of the magnetic block 14 to achieve precise positioning.

[0024] The top of the anti-slip fixing layer 1 is provided with four positioning protrusions 16, which are located at the four corners of the anti-slip fixing layer 1. The four positioning protrusions 16 have smooth, burr-free surfaces and serve as guides and limiters. A snap-lock seat 17 is provided in the groove at the top of the positioning protrusion 16. The snap-lock seat 17 has an elastic claw structure, which can be unlocked and separated by pressing. The four positioning protrusions 16 are slidably connected to the middle filter water absorption layer 10. The middle filter water absorption layer 10 can slide up and down along the axial direction of the positioning protrusions 16, and is easy to assemble and disassemble. The bottom of the middle filter water absorption layer 10 is provided with three magnetic blocks 14. The magnetic block 14 corresponds one-to-one with the positioning groove 18, uses neodymium iron boron strong magnetic material, and has stable adsorption force. The bottom of the magnetic block 14 is magnetically adsorbed and connected to the top of the magnetic plate at the bottom of the inner side of the positioning groove 18. The intermediate filter water absorption layer 10 and the anti-slip fixing layer 1 are quickly pre-fixed through magnetic adsorption. The outer side of the intermediate filter water absorption layer 10 is provided with four guide grooves 15. The inner diameter of the four guide grooves 15 is clearance-fitted with the outer diameter of the positioning protrusion 16, and the inner wall is provided with a lubricating coating. The inner side of the guide groove 15 is slidably connected to the outer side of the positioning protrusion 16 to ensure that the intermediate filter water absorption layer 10 does not deviate during the sliding process and is accurately positioned.

[0025] Example 2: Please refer to Figure 2 , Figure 3 and Figure 5 The intermediate water-absorbing filter layer 10 includes an upper activated carbon filter layer 11, a middle superabsorbent resin water storage layer 12, and a lower breathable barrier mesh 13. The upper activated carbon filter layer 11 is filled with columnar activated carbon to adsorb odors and small impurities. The middle superabsorbent resin water storage layer 12 is made of high-ratio SAP particles and has strong water-locking ability. The lower breathable barrier mesh 13 is made of nylon, which is breathable, leak-proof, and has good support. The three layers are fixed together by heat pressing. On the one hand, the middle superabsorbent resin water storage layer 12 has high water-locking ability. The water-retaining function prevents water stains from creating a damp environment, reducing the breeding ground for bacteria and mold. On the other hand, the replaceable structure allows for the periodic disassembly and cleaning of the removable non-woven filter 8 and the intermediate filter water-absorbing layer 10. This thoroughly removes dust trapped by the filter, residual water stains adsorbed by the water storage layer, and impurities adsorbed by the upper activated carbon filter layer 11. The upper activated carbon filter layer 11 continuously adsorbs odors without relying on chemical antibacterial agents. Through the synergistic effect of physical cleaning and drying protection, a long-lasting antibacterial effect is achieved, preventing the generation of odors.

[0026] The buckle seat 17 is externally engaged with the buckle female seat 9. The buckle female seat 9 has a groove on its inner side that matches the elastic claw. After engagement, the connection is firm and not easy to loosen. The buckle female seat 9 is externally slidably connected to the top groove of the positioning protrusion 16. It can move along the groove axis to realize engagement and unlocking actions. The top of the four buckle female seats 9 is provided with a surface functional layer 4. The surface functional layer 4 is made of TPE environmentally friendly material, which is flexible and resistant to high and low temperatures. The top of the surface functional layer 4 is provided with multiple anti-slip protrusions 5. The multiple anti-slip protrusions 5 are evenly distributed in a matrix and have an arc-shaped structure at the top to increase the friction of the shoe sole. The four anti-slip protrusions 5 are provided with inverted conical dust suction holes 6 on the horizontally similar side. The inverted conical dust suction holes 6 have a funnel-shaped structure that is larger at the top and smaller at the bottom, which facilitates dust settling and prevents backflow. The external of the multiple inverted conical dust suction holes 6 is opened on the top of the surface functional layer 4, covering the main stress area of ​​the surface functional layer 4.

[0027] A removable non-woven fabric filter 8 is embedded in the filter installation groove at the bottom of the surface functional layer 4. It is made of meltblown fabric, has high filtration accuracy, and can be washed and replaced separately. An annular sealing edge 7 is provided at the top of the surface functional layer 4. The annular sealing edge 7 is integrally formed with the surface functional layer 4 and has elastic sealing performance. A hook and loop fastener is provided at the top of the annular sealing edge 7. The hook and loop fastener are attached to the hook and loop fastener 3 to achieve a three-layer circumferential seal.

[0028] Based on the above embodiments, the following is the complete working principle of the above embodiments: During assembly, the intermediate filter absorbent layer 10 is first slidably fitted onto the positioning protrusion 16 on the top of the anti-slip fixing layer 1 through the bottom guide groove 15, so that the three magnetic blocks 14 at the bottom of the intermediate filter absorbent layer 10 are precisely embedded into the positioning groove 18 of the anti-slip fixing layer 1, forming magnetic adsorption positioning with the magnetic sheet at the bottom of the positioning groove 18, thus completing the initial fixing of the intermediate filter absorbent layer 10 and the anti-slip fixing layer 1. Then, the snap-on female seat 9 at the bottom of the surface functional layer 4 is aligned with the snap-on male seat 17 in the groove at the top of the positioning protrusion 16, and the surface functional layer 4 is pressed to make the snap-on female seat 9 and the snap-on male seat 17 engage. The seat 17 is locked in place, and at the same time, the Velcro hook surface at the top of the annular sealing edge 7 of the surface functional layer 4 is bonded to the Velcro rough surface 3 on the inner side of the outer elastic wrapping edge 2 of the anti-slip fixing layer 1, achieving double fixing and sealing of the three-layer structure. When disassembling, press the elastic claw of the buckle seat 17 inward to unlock, and the surface functional layer 4 and the middle filter water absorption layer 10 can be separated upward. The middle filter water absorption layer 10 can be separated from the anti-slip fixing layer 1 by overcoming the adsorption force of the magnetic block 14 and the magnetic sheet and sliding upward along the positioning protrusion 16. The detachable non-woven fabric filter screen 8 on the surface can be directly removed from the filter screen installation groove, realizing the individual replacement and maintenance of each functional layer.

[0029] When dust or water stains on the soles of the shoes of drivers and passengers come into contact with the surface functional layer 4, the anti-slip protrusions 5 on the surface play a preliminary anti-slip and diversion role. The dust is embedded into the inverted conical dust suction holes 6 by the pressure of the sole. Because the inverted conical dust suction holes 6 have an inverted conical structure that is larger at the top and smaller at the bottom, the dust settles to the bottom of the hole under the action of gravity and airflow. It is intercepted and filtered by the detachable non-woven fabric filter 8 embedded at the bottom of the hole, preventing the dust from scattering or seeping. Water stains on the soles of the shoes seep through the gap between the inverted conical dust suction holes 6 and the detachable non-woven fabric filter 8 to the middle filter water absorption layer 10. First, the upper activated carbon filter layer 11 adsorbs the odor and small impurities in the water stains, and then the middle super absorbent resin water storage layer 12 quickly absorbs and locks in the moisture, preventing the water stains from further seeping into the anti-slip fixing layer 1 and the car body. The carpet achieves a synergistic dust-proof and water-absorbing effect by classifying and intercepting dust and effectively locking in water stains. The bottom of the anti-slip fixing layer 1 is in direct contact with the main carpet of the car. Its own foamed rubber substrate and the anti-slip structure at the bottom enhance the friction with the main carpet. At the same time, the elastic wrapping edge 2 plays a circumferential limiting role for the overall structure. The middle filter water-absorbing layer 10 and the anti-slip fixing layer 1 are precisely positioned by the magnetic adsorption of the magnetic block 14 and the magnetic sheet, and the sliding limitation of the guide groove 15 and the positioning protrusion 16. The surface functional layer 4 and the anti-slip fixing layer 1 are locked by the snap fastener 9 and the snap fastener 17, and the Velcro hook surface and the Velcro pile surface 3 are bonded and sealed to form a double fixation, which effectively prevents the floor mat from shifting or sliding during car driving and ensures driving safety.
