specific Embodiment 2

[0030] The specific embodiment 2 of the negative Poisson's ratio mattress of the present invention is different from the specific embodiment 1 in that the negative Poisson's ratio hole processed by punching inside the latex layer can be a hand-shaped cross-sectional shape, and the hand-shaped hole also has a negative Poisson's ratio hole. The characteristics of Poisson's ratio structure can also enhance its elastic support performance during compression. In other embodiments, the cross-sectional shape of the negative Poisson's ratio holes may also be sword-like or honeycomb-like.

specific Embodiment 3

[0031] The specific embodiment 3 of the negative Poisson's ratio mattress of the present invention is different from the specific embodiment 1 in that the negative Poisson's ratio three-dimensional support structure can be similar to the honeycomb negative poise in the composite sandwich bulletproof structure scheme in the background technology. The loose ratio structure can also effectively support the user's body, ensuring that the structure remains stable and reliable after long-term compression.

specific Embodiment 4

[0032] The specific embodiment 4 of the negative Poisson's ratio mattress of the present invention is different from the specific embodiment 1 in that the mattress can be a negative Poisson's ratio three-dimensional support structure sandwiched between two latex layers and two latex layers, The double latex layer can achieve the effect of double-sided use. Compared with the structure of one latex layer and one rubber layer, the operation of distinguishing the reverse side is omitted, which is convenient for the user's actual use. In other embodiments, the latex layer can be replaced by a sponge layer made of sponge material, or a cushion layer made of other materials.

Abstract

The invention provides a negative poisson ratio mattress and relates to the field of mattresses. The negative poisson ratio mattress comprises two layers of cushion layers arranged in a spaced mode, and a negative poisson ratio three-dimensional structure arranged between the two cushion layers, negative poisson ratio holes are formed inside at least one of the cushion layers, and the negative poisson ratio holes with different poisson coefficients are formed in the thickness direction of the cushion layers. When the mattress is pressed, the negative poisson ratio three-dimensional structure is contracted inwards, the elastic strength of the mattress is improved, thus the elastic supporting effect is better realized, the body of a user can be effectively supported, it is guaranteed that the structure is still stable and reliable after the mattress is pressed for a long term, meanwhile, due to existence of the negative poisson ratio holes, the smaller the pressure borne by the cushion layers is, the easier compressive deformation is, otherwise, the larger the pressure is, the more difficult compressive deformation is, the user obtains soft supporting of the early stage firstly, subsequent and more powerful elastic supporting can be obtained with increasing of the pressure and the compression amount, finally, double properties of softness and comfort and powerful springback are presented, and the product experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of mattresses, in particular to a negative Poisson's ratio mattress. Background technique [0002] Ordinary mattresses generally use a sponge layer to wrap the internal spring structure, which elastically supports the user through the internal spring. In actual use, if the mattress is stressed beyond the limit of the spring or bears an unbalanced load for a long time, the spring is prone to irreversible damage. deformation, which affects the user experience and the effect of the product. [0003] For example, the Chinese invention patent application with application publication number CN108050891A and application publication date of 2018.05.18 discloses a composite sandwich bulletproof structure, and specifically discloses that the composite sandwich bulletproof structure includes a composite sandwich layer, a panel and a The sandwich layer is composed of a honeycomb negative Poisson's ratio structure and a...
