Description

Technical Field

[0001] This utility model relates to the field of seat surface material technology, and in particular to anti-slip and wear-resistant seat surface material for engineering seats. Background Technology

[0002] Engineering chairs are designed to meet the specific needs of engineering or work environments. These chairs typically prioritize durability, comfort, and ergonomic design to accommodate long hours of work or specific work postures. The seat surface of engineering chairs is usually made of fabric, leather, plastic, and other materials.

[0003] Currently, during use, the fabric or PVC material on seat surfaces is prone to scratches and pilling due to long-term friction, resulting in a decrease in anti-slip performance. Furthermore, relying on a single internal polyurethane foam layer or sponge material for shock absorption is ineffective and fails to effectively distribute local pressure, leading to a decrease in comfort. Therefore, we propose an anti-slip and wear-resistant seat surface material for engineering seats to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a non-slip and wear-resistant seat surface material for engineering seats, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The engineering seat anti-slip and wear-resistant seat surface material includes an anti-slip layer, a reinforcing layer, a shock-absorbing layer and an absorption layer. The upper surface of the anti-slip layer is provided with a biomimetic shark layer structure. The shock-absorbing layer has multiple elastic elements inside and is filled with magnetorheological fluid. The absorption layer has silicone honeycomb blocks inside and a reinforcing strip inside, which is filled with polyurethane foam.

[0007] In a further embodiment, the outer surface of the anti-slip layer is provided with an edge-sealing layer, which is connected to the anti-slip layer, the reinforcing layer, the shock-absorbing layer and the absorption layer by hot melt adhesive.

[0008] In a further embodiment, the bottom end of each elastic element is connected to the inner bottom wall of the damping layer, and the top end of each elastic element is connected to the inner top wall of the damping layer.

[0009] In a further embodiment, the silicone honeycomb blocks are arranged in a regular hexagonal pattern, and the interior of the silicone honeycomb blocks is filled with multiple capsules.

[0010] In a further embodiment, the bottom surface of the anti-slip layer and the upper surface of the reinforcing layer are jointly provided with an antibacterial coating, and the interior of the antibacterial coating is provided with nano zinc oxide and silver ion modified silica.

[0011] In a further embodiment, the reinforcing layer contains Kevlar fibers and polyester fibers in a ratio of six to four.

[0012] In a further embodiment, the outer surface of the damping layer is provided with a self-healing polyurethane coating, and the self-healing polyurethane coating comprises diphenylmethane diisocyanate prepolymer and polytetrahydrofuran ether diol.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device improves the stability of the static friction coefficient by setting a biomimetic shark layer structure on the surface of the anti-slip layer, making the surface durable and wear-resistant, and reducing scratches and fuzzing. It absorbs vibration by forming a multi-level shock absorption mechanism through the hexagonal elastic deformation of the silicone honeycomb block under pressure, the viscosity of the magnetorheological fluid, the damping vibration of the polyurethane foam in the reinforcing strip through the closed-cell structure, the elastic deformation of the elastic element, and the deformation of the air capsule. It can disperse local pressure to the entire absorption layer and has excellent compression and rebound performance. Attached Figure Description

[0024] Please see Figure 1-5In this utility model, the anti-slip and wear-resistant seat surface material for engineering seats includes an anti-slip layer 1, a reinforcing layer 2, a shock-absorbing layer 3, and an absorption layer 4. The upper surface of the anti-slip layer 1 is provided with a biomimetic shark layer structure 6. The shock-absorbing layer 3 has multiple elastic elements 7 inside and is filled with magnetorheological fluid 8. The absorption layer 4 has silicone honeycomb blocks 9 inside and a reinforcing band 11 inside, which is filled with polyurethane foam 12. The elastic elements 7 are helical springs and are evenly distributed on the inner bottom wall of the shock-absorbing layer 3. The magnetorheological fluid 8 is composed of tiny soft particles with high magnetic permeability and low magnetic hysteresis. The suspension is composed of magnetic particles and non-magnetic liquid. Under zero magnetic field conditions, this suspension exhibits low viscosity Newtonian fluid characteristics, while under strong magnetic field conditions, it exhibits high viscosity and low fluidity characteristics. The reinforcing band 11 is woven from aramid fibers and polyurethane, with aramid fibers accounting for more than 60%. Through the elastic deformation of silicone honeycomb blocks 9, the viscosity of magnetorheological fluid 8, the vibration damping of polyurethane foam 12 in the reinforcing band 11 through closed-cell structure, and the elastic deformation of elastic element 7, a multi-level damping mechanism is formed to absorb vibration and disperse local pressure to the entire absorption layer 4.

[0025] The outer surface of the anti-slip layer 1 is provided with an edge layer 5. The edge layer 5 is connected to the anti-slip layer 1, the reinforcing layer 2, the shock-absorbing layer 3 and the absorption layer 4 by hot melt adhesive. The bottom end of each elastic element 7 is connected to the inner bottom wall of the shock-absorbing layer 3, and the top end of each elastic element 7 is connected to the inner top wall of the shock-absorbing layer 3. The silicone honeycomb blocks 9 are arranged in a regular hexagonal shape. The inside of the silicone honeycomb blocks 9 is filled with multiple capsules 10, and the inside of each capsule 10 is filled with air.

[0026] The bottom surface of the anti-slip layer 1 and the upper surface of the reinforcing layer 2 are jointly provided with an antibacterial coating 13. The antibacterial coating 13 contains nano zinc oxide and silver ion modified silica. The reinforcing layer 2 contains medium Kevlar fiber and polyester fiber in a ratio of 6:4. The outer surface of the shock-absorbing layer 3 is provided with a self-healing polyurethane coating, which contains diphenylmethane diisocyanate prepolymer and polytetrahydrofuran ether diol. When the self-healing polyurethane coating is scratched, the isocyanate groups react with moisture in the air to form urea bonds, thereby closing the micro-cracks.

[0027] The working principle of this utility model is as follows:

[0028] When using this device, it is installed on the base of the seat. The force transmission path of this device is as follows: external load to anti-slip layer 1 to reinforcement layer 2 to shock-absorbing layer 3 to absorption layer 4 to base. When the silicone honeycomb block 9 is compressed, the hexagonal unit undergoes elastic deformation. The magnetorheological fluid 8 generates a shear thickening effect under the magnetic field. The polyurethane foam 12 in the reinforcing strip 11 dampens the vibration through the closed-cell structure, forming a three-stage shock absorption mechanism to absorb the vibration.
