Multi-channel aeroelastic sofa with bionic cushioning layer

Abstract

The invention discloses a multi-channel aeroelastic sofa with a bionic cushioning layer. The sofa comprises a sofa outer frame, an integrated soft cushion attached to the wall surface of the sofa outer frame is arranged on the inner side of the sofa outer frame; the sofa outer frame consists of armrest side plates, backrest side plates and a bearing bottom plate; the integrated soft cushion is divided into a cushion part and a back cushion part according to the attaching position, a bionic cushioning layer is arranged between the cushion part and the bearing bottom plate, the exterior of bionic cushioning layer is wrapped with a closed main air bag, the space between the integrated soft cushion is filled with a plurality of sets of evenly-distributed rubber air bags, and the main air bag and the rubber air bags are communicated through adjustable valves. The bionic cushioning layer is added, the bionic cushioning layer is of a bionic leg structure, the cushioning effect is improved through nonlinear rigidity, meanwhile, the horizontal state of the bionic cushioning layer can be kept through the structural design of the parallel sliding blocks, the overall stress area is increased,and the comfort degree and stability of the sofa are improved.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a multi-channel aeroelastic sofa with a bionic cushioning layer. Background technique [0002] A sofa is an upholstered, multi-seat chair. A chair with a spring or thick foam plastic, etc., with armrests on both sides, is a kind of upholstered furniture. The industry standard mentions the durability index according to the revised mechanical property requirements of QB / T1952.1-1999. The filling of the sofa includes soft polyurethane foam (sponge), down filling, and artificial cotton filling. Among them, sponges are mainly divided into three categories: conventional sponges have good resilience, softness, breathability, and high resilience. Sponge has excellent mechanical properties, good elasticity, large compression load, flame resistance, and good air permeability; random-pore sponge has good elasticity, and has excellent cushioning performance when compressed and rebounded;...

AI Technical Summary

Problems solved by technology

[0004] The cushioning technology usually used in the prior art is to change the filler or add a spring, which has the following deficiencies: (1) The use of the filler needs to comprehensively consider the resilience and life, and the filler often loses its strength when a certain posture is maintained for a long time. The rebound effect will be greatly reduced, which is far less reliable than the mechanical structure; (2) The application of springs in cushioning can be said to be overwhelming, but spring cushioning in sofas is prone to differences between the spring compression area and the edge area state, it is required to increase the number of springs used, and the "spring feeling" cannot be avoided; (3) the effect of spring cushioning is mainly for displacement, and the stiffness remains unchanged, and the effect is general in actual use; (4) there are children in the home on the sofa The situation of playing around on the Internet is more obvious. When the foot is stepped on the sofa, it will be sunken, and the cushioning cannot be moved up and down as a whole, so the uneven surface of the sofa will cause accidents such as sprains; (5) Air cushion cushioning is currently in the field of shoes It is widely used, but not enough in sofas. In addition, aeroelastic cushioning requires not only the viscoelasticity of the gas, but also the overall fluidity of the gas to increase the wrapping performance and reduce the body contact pressure.
