Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, in particular to a leather base fabric used for a noise reduction foot pad. Background Art

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of leather. It is usually made of fabric as the base, coated with synthetic resin and various plastic additives. The existing sound-absorbing and noise-reducing leather base fabric can be used in the fields of automobile interior and interior decoration, and it contains a sound insulation layer to reduce noise. Car floor mats are an environmentally friendly automobile interior component that integrates five main functions: water absorption, dust absorption, decontamination, sound insulation, and protection of the main body carpet. Thick car floor mats can block chassis noise and tire noise, and improve driving comfort. Car floor mats can also completely absorb the remaining noise and echoes of the car audio, etc., to protect hearing from damage. The sound insulation layer of the floor mats made of leather base fabrics is prone to collapse after long-term use, resulting in a decrease in the noise reduction effect, and it is easy to slip when the foot mats are not closely attached to the car, affecting driving safety. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art and provides a leather base fabric for noise reduction type foot pads, which has high noise reduction and anti-slip properties and effectively improves driving comfort and safety.

[0004] The utility model solves the technical problem by adopting a technical solution: a leather base fabric for a noise-reducing foot pad, comprising a polyurethane resin layer, a base fabric layer, a sound-absorbing layer and an anti-skid pad layer, wherein the polyurethane resin layer, the base fabric layer, the sound-absorbing layer and the anti-skid pad layer are fixedly bonded and arranged in sequence from top to bottom, a plurality of sound-absorbing recessed holes are arranged on the lower side surface of the sound-absorbing recessed holes, support pads are gap-fittedly arranged in the sound-absorbing recessed holes, a positioning boss is arranged at the bottom of the support pad, a positioning hole is arranged on the anti-skid pad layer, and the positioning hole is plug-fitted with the positioning boss.

[0005] For further improvement, the support pad is provided with sound-absorbing holes.

[0006] Further improvement, a protective layer is arranged on the polyurethane resin layer, and the protective layer is a PC film or an organic silicon layer.

[0007] For further improvement, the positioning hole passes through the anti-slip cushion layer, and an elastic contact head is provided at the bottom of the positioning boss.

[0008] The beneficial effects of the utility model are as follows: adding reinforcement structure and anti-skid design, effectively solving the problem of sound insulation layer collapse and pad sliding after long-term use of leather-based cloth pads, improving the technical performance and safety of the product, and providing users with a better use experience and driving safety guarantee. Adding reinforcement structure under the sound-absorbing layer, designing support pads to improve the load-bearing capacity and stability of the sound-absorbing layer, and reducing the risk of collapse. Adding an anti-skid pad layer at the bottom of the pad or the part in contact with the vehicle increases friction and prevents the pad from sliding during driving, thereby improving driving safety. This solution adopts a multi-layer structural design, which can not only improve the durability of the entire pad, but also extend the service life, reduce the number of replacements, and save use costs.

DETAILED DESCRIPTION

[0011] The utility model is further described below in conjunction with the accompanying drawings:

[0012] See attached Figure 1 : In this embodiment, a leather base fabric for a noise reduction foot pad includes a polyurethane resin layer 1, a base fabric layer 2, a sound-absorbing layer 3 and an anti-skid pad layer 4. The polyurethane resin layer 1, the base fabric layer 2, the sound-absorbing layer 3 and the anti-skid pad layer 4 are fixedly bonded and arranged in sequence from top to bottom. The polyurethane resin layer, as the top layer, can provide waterproof and wear-resistant properties, increase the durability and service life of the foot pad. The base fabric layer 2, as a supporting layer, has good strength and stability, can maintain the shape of the foot pad and provide a comfortable stepping feeling.

[0013] A plurality of sound-absorbing recessed holes 5 are provided on the lower side of the sound-absorbing layer 3, and support pads 6 are provided in the gaps inside the sound-absorbing recessed holes 5. The sound-absorbing layer is located below the base fabric layer. Through the design of the sound-absorbing recessed holes and the support pads, noise can be effectively absorbed and isolated, the noise reduction effect can be improved, and the problem of collapse of the sound insulation layer can be avoided.

[0014] The bottom of the support pad 6 is provided with a positioning boss 7, and the anti-skid pad layer 4 is provided with a positioning hole 8, which is plugged into the positioning boss 7. The anti-skid pad layer is located at the bottom, and the positioning boss and the positioning hole cooperate to ensure that the foot pad fits tightly with the vehicle, reduce the possibility of sliding, and improve driving safety.

[0015] This solution uses a structural design of a polyurethane resin layer, a base fabric layer, a sound-absorbing layer and an anti-slip pad layer. It effectively solves the problem of reduced noise reduction effect caused by the collapse of the sound insulation layer after long-term use of foot mats made of leather base fabric, and the problem of slipping when the foot mats are not closely fitted to the car, thereby improving driving safety and user experience.

[0016] The support pad 6 is provided with sound-absorbing holes 9, which can further increase the sound-absorbing area of ​​the sound-absorbing layer, improve the noise reduction effect, and maintain the stability of the sound-absorbing effect of the sound-absorbing layer.

[0017] The polyurethane resin layer 1 is provided with a protective layer 10, which can improve the wear resistance and waterproofness of the foot pad, facilitate cleaning and maintenance, and increase the aesthetics of the foot pad. The protective layer 10 is a PC film or an organic silicon layer.

[0018] Polycarbonate, referred to as PC, is one of the five general engineering plastics with excellent performance in all aspects. Polycarbonate film or PC film is a film made of polycarbonate resin as the base material. PC film has excellent wear resistance and can effectively protect the polyurethane resin layer from friction, scratches and wear. It can extend the service life of the floor mat and increase its durability. PC film has good resistance to some chemicals. It can resist the erosion of certain solvents, acids and alkalis and other chemicals, preventing the polyurethane resin layer from being corroded or damaged. Due to the smooth surface characteristics of PC film, it is easier to clean. Simply wipe with a damp cloth to remove pollutants such as dust and stains, keeping the appearance of the floor mat clean.

[0019] As a protective layer, the silicone layer has the advantages of high temperature resistance, chemical corrosion resistance, wear resistance, high transparency and softness, which can effectively protect the foot pad and improve its performance and service life.

[0020] The positioning hole 8 passes through the anti-skid cushion layer 4, and an elastic contact head 11 is provided at the bottom of the positioning boss 7. The elastic contact head 11 plays a role in buffering and shock absorption, can effectively absorb vibration and impact force, reduce the risk of damage caused by changes in the external environment, and extend the service life of the product. The contact design of the elastic contact head can also increase the anti-skid effect of the anti-skid cushion layer, ensure that the product is not easy to tilt or slide during use, and improve the user experience.

[0021] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
