[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.
[0018] A kind of high resilience sofa sponge, such as Figures 1-4As shown, it comprises protective cloth 1, memory sponge 2, honeycomb plate 3, first support plate 4, second support plate 5, high resilience polyurethane foam 6, spring assembly, rubber pad 10 and fixed strip 12, the protective cloth 1 is hollow cubic type, the protective cloth 1 is provided with ventilation hole 11, the protective cloth 1 is fixedly connected with fixed strip 12 at the edge of outer wall, the protective cloth 1 is fixedly connected with memory sponge 2 and high resilience polyurethane foam 6 inside, the memory sponge 2 is fixedly connected with first support plate 4 at the bottom, the memory sponge 2 is fixedly connected with honeycomb plate 3 between first support plate 4, the honeycomb plate 3 is provided with honeycomb hole, the high resilience polyurethane foam 6 is fixedly connected with second support plate 5 at the top, three spring assemblies and four rubber pads 10 are connected between first support plate 4 and second support plate 5, three spring assemblies and four rubber pads 10 are staggered left and right.
[0019] As shown in the figure, Figures 2-4 The spring assembly comprises connecting column 7, connecting sleeve 8 and spring 9, three connecting sleeves 8 are fixedly connected with second support plate 5 away from high resilience polyurethane foam 6, connecting column 7 is slidingly connected in connecting sleeve 8, connecting column 7 is fixedly connected with first support plate 4, spring 9 is fixedly connected between connecting sleeve 8 and connecting column 7.
[0020] In use, the sofa sponge is placed on the seat of the sofa, and the fixing strips 12 can provide additional support for the edge area of the sofa sponge, help maintain the overall shape and structure of the sofa sponge, prevent deformation or collapse due to long-term use, and prevent the sofa sponge from moving during use. When the user sits on the sofa sponge, the memory sponge 2 is compressed under the action of the user's gravity, and the memory sponge 2 transmits the force to the connecting column 7 and the rubber pad 10. The connecting column 7 slides downward along the connecting sleeve 8, the spring 9 is compressed, and the rubber pad 10 is compressed and deformed. The connecting sleeve 8 and the rubber pad 10 transmit the force to the high-resilience polyurethane foam 6, which is compressed and deformed. When the user leaves the sofa sponge, the user's gravity acting on the sofa sponge disappears, and the memory sponge 2, the spring 9, the rubber pad 10 and the high-resilience polyurethane foam 6 all return to their original state. The spring 9 returns to its original state, causing the connecting column 7 to slide back to its original position. The honeycomb board 3 can evenly distribute the force of the memory sponge 2, thereby reducing the local high stress on the spring 9, the high-resilience polyurethane foam 6 and the rubber pad 10, helping to slow down the aging and deformation process of the sofa sponge, thereby prolonging the overall service life of the sofa sponge. According to the unique molecular structure of the high-resilience polyurethane foam 6, the high-resilience polyurethane foam 6 can quickly return to its original state after long-term use, maintain the shape and support of the sofa sponge, and is not prone to deformation or loss of elasticity after long-term use, prolonging the service life of the sofa sponge. The rubber pad 10 and the rebound assembly can provide additional support for the sofa sponge, and by sharing the load, the rubber pad 10 and the rebound assembly can reduce the burden on the memory sponge 2 and the high-resilience polyurethane foam 6, slowing down the aging process of the sofa sponge and further prolonging the service life of the sofa sponge. Under the combined action of the ventilation holes 11 and the rebound assembly, the sofa sponge has a heat dissipation function, keeping the interior of the sofa dry and further improving user comfort.
[0021] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
