Description

Technical Field

[0001] The utility model relates to the technical field of mattresses, in particular to a low-noise sponge airbag spring. Background Art

[0002] Currently, most smart mattresses on the market utilize a support structure composed of multiple air cells, typically cylindrical or rectangular in shape. These cells, connected to an inflation and deflation system that controls airflow, enable precise adjustment of the mattress's firmness. These cells are typically made of rubber or TPU (thermoplastic polyurethane), have a hollow interior, and are equipped with drawstrings or wires to ensure shape stability after inflation.

[0003] However, during use, when the air pressure is insufficient and the mattress is rubbed or squeezed repeatedly, the airbag will produce large deformation and air fluctuations, which will cause serious noise problems.

[0004] To alleviate this problem, existing technologies typically employ a thick, soft cushioning layer placed on top of the airbags. While this approach reduces noise transmission to some extent, it also introduces new challenges. On the one hand, the thicker cushioning layer increases the overall thickness and weight of the mattress, slowing down the mattress's response when adjusting firmness, thus reducing the user's adjustment experience. On the other hand, the thicker cushioning layer can also affect the mattress's breathability and comfort, significantly reducing the mattress's adjustment effectiveness.

[0005] Therefore, how to provide a low-noise sponge airbag spring that reduces the deformation of the elastic body and air fluctuations when squeezed by external force or evacuated, thereby reducing noise is a technical problem that technicians in this field currently need to solve. Utility Model Content

[0006] The utility model aims to provide a low-noise sponge airbag spring, which solves the technical problem of high noise in the use of existing airbags.

[0007] To achieve the above-mentioned object, the utility model provides a low-noise sponge airbag spring, comprising a plurality of sponge airbag units in a vertical direction; both sides of the sponge airbag units are V-shaped structures, so that both sides of the low-noise sponge airbag spring are corrugated structures;

[0008] Wherein, each sponge airbag unit is provided with an air flow channel in the vertical direction, adjacent sponge airbag units are connected through the air flow channel, and the air flow channel of the sponge airbag unit at the top is connected to the air supply system through an air nozzle.

[0009] Preferably, the sponge airbag unit includes a sponge body and an elastic body sleeved on the outer surface of the sponge body, and the sponge body is a breathable elastic sponge core.

[0010] Preferably, the sponge is cylindrical or cubic.

[0011] Preferably, a plurality of V-shaped grooves are provided on the side surfaces of the sponge body, and the oblique sides of the V-shaped grooves extend to the edges on both sides.

[0012] Preferably, a plurality of concave grooves are provided on the side surfaces of the sponge body, and the oblique sides of the concave grooves extend to the edges on both sides.

[0013] Preferably, the sponge body and the elastic body are connected by bonding, and the adjacent sponge airbag units are connected by bonding.

[0014] Preferably, the sponge airbag unit includes two sponge airbag monomers in the shape of rectangular pyramids.

[0015] Compared with the above-mentioned background technology, the low-noise sponge airbag spring provided by the present invention includes a sponge airbag unit arranged in the vertical direction. The two sides of the sponge airbag unit are V-shaped structures, so that the two side surfaces of the low-noise sponge airbag spring are corrugated structures. The corrugated structure can enhance the elastic deformation ability of the airbag, thereby better absorbing and dispersing external forces. In summary, the low-noise sponge airbag spring provided by the present application can reduce the deformation and air fluctuations of the low-noise sponge airbag spring when it is squeezed by external force or vacuumed through the design of the corrugated structure, thereby reducing the generation of noise.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] See also Figure 1-Figure 3 The present application provides a low-noise sponge airbag spring, which includes several sponge airbag units 1 in the vertical direction; the two sides of the sponge airbag unit 1 are V-shaped structures 2, so that the two side surfaces of the low-noise sponge airbag spring 3 are corrugated structures; wherein, each sponge airbag unit 1 is provided with an airflow channel in the vertical direction, and adjacent sponge airbag units 1 are connected through the airflow channel, and the airflow channel of the top sponge airbag unit 1 is connected to the air supply system through the air nozzle.

[0027] Specifically, the sponge airbag units 1 stacked vertically constitute a low-noise sponge airbag spring 3. Since each sponge airbag unit 1 has a V-shaped structure 2 on both sides, the two sides of the low-noise sponge airbag spring 3 exhibit a corrugated structure. This corrugated structure is similar to the corrugated structure on the outer circumference of a spring, which can enhance the elastic deformation capacity of the airbag. When the upper surface is uniformly stressed or evacuated, it will change in height like a spring, while slightly deforming or not deforming radially, thereby effectively absorbing and dispersing external forces. When inflated, its height changes slightly and slightly deforms or not deforming radially, thereby better absorbing and dispersing external forces. Each sponge airbag unit 1 is provided with an airflow channel in the vertical direction, allowing air to flow freely within the low-noise sponge airbag spring 3. The airflow channels of adjacent sponge airbag units 1 are connected by air nozzles, forming an integrated airflow network. The air nozzles located at the top or bottom are connected to the inflation and deflation system, realizing precise inflation and deflation control of the low-noise sponge airbag spring 3.

[0028] In summary, the low-noise sponge airbag spring provided in this application can reduce the deformation and air fluctuations of the low-noise sponge airbag spring 3 when it is squeezed by external force or evacuated through the design of the corrugated structure, thereby reducing the noise generation by reducing the deformation and fluctuations.

[0029] Specifically, the shape of the formed corrugated structure is not limited and can be a regular corrugated structure or an irregular corrugated structure.

[0030] Based on the above embodiment, the sponge airbag unit 1 includes a sponge body and an elastic body sleeved on the outer surface of the sponge body, and the sponge body is an air-permeable elastic sponge core.

[0031] That is to say, the sponge body adopts a breathable elastic sponge core, which not only has good elasticity but also has excellent air permeability, which helps to maintain air circulation inside the mattress and reduce moisture and stuffiness; the breathable elastic sponge core can effectively absorb and disperse external forces, reduce the deformation of the low-noise sponge airbag spring 3 when squeezed, thereby reducing the generation of noise.

[0032] The elastomer is usually made of a soft and durable material, such as rubber or TPU (thermoplastic polyurethane). The elastomer is tightly fitted on the outer surface of the sponge body to form a protective layer, which not only prevents the sponge body from being damaged by the outside world, but also further enhances the support performance and stability of the low-noise sponge airbag spring 3.

[0033] On the basis of the above embodiment, the sponge body and the elastic body are connected by bonding, and the adjacent sponge airbag units 1 are connected by bonding.

[0034] That is, before bonding, the bonding surfaces of the sponge and elastomer should be cleaned and treated to remove impurities such as oil, dust, etc. to improve the bonding effect. Then, the adhesive is evenly applied to the bonding surface, the sponge is inserted into the elastomer, and appropriate pressure and temperature are applied to allow the adhesive to fully penetrate and cure. The elastomer in this application is a hot melt adhesive film or a dual-temperature film.

[0035] Alternatively, the elastomer of the present application is a liquid elastic material, which is evenly covered on the outer peripheral surface of the sponge by spraying to ensure close bonding with the sponge. After spraying, the material solidifies under certain conditions to form a layer of dense elastomer, which is then combined with the sponge to form a sponge airbag unit 1.

[0036] Before bonding adjacent sponge airbag units, the bonding surfaces also need to be cleaned and treated. Then, apply adhesive to the contact surfaces of the adjacent units and apply appropriate pressure to make them fit tightly together. During the bonding process, always check the connection status of the air nozzle to ensure that the air flow channel can be smoothly connected after bonding.

[0037] Based on the above embodiment, the sponge is a rectangular parallelepiped or a round body, and the side of the sponge is provided with a plurality of V-shaped grooves or a plurality of concave grooves to form a V-shaped structure 2, and the oblique sides of the V-shaped grooves or concave grooves extend to the edges on both sides.

[0038] Specifically, the depth of the V-shaped groove or concave groove of the present application can be selected according to actual needs, and the depth can be preferably 10 mm.

[0039] Preferably, the sponge of the present application is a rectangular parallelepiped, which is convenient for processing, assembly and transportation.

[0040] Several V-shaped grooves are formed on the side of the sponge by cutting or molding (see Figure 2 ) or concave groove (see Figure 3 The structure formed by the V-shaped groove or concave groove is called V-shaped structure 2. The oblique sides of the V-shaped structure 2 extend to the edges of both sides of the sponge body, forming a continuous wavy or concave-convex appearance.

[0041] Specifically, the number of V-grooves or concave grooves is one or more, which can be selected according to actual needs. When the number of V-grooves or concave grooves is multiple, they are arranged in parallel on the side of the sponge. In this embodiment, the number of V-grooves or concave grooves is preferably one.

[0042] Example 2

[0043] See also Figure 4 The difference between Example 2 and Example 1 is that the sponge airbag unit 1 of Example 1 is an integrated structure, and the sponge airbag unit 1 of Example 2 is a split structure, that is, it is symmetrically composed of two sponge airbag monomers 11 in the shape of a rectangular prism. Similarly, the sponge airbag monomer 11 includes a sponge body and an elastomer sleeved on the outer surface of the sponge body, that is, the shape of the sponge body is a rectangular prism, and the top cross-sectional area of ​​the sponge airbag monomer is smaller than the bottom cross-sectional area. The upper and bottom surfaces of the two sponge airbag monomers are connected correspondingly to form a sponge airbag unit. It can also be understood that the smaller side of the two sponge airbag monomers is connected, and the side of the sponge airbag unit 1 formed is a concave structure, that is, a V-shaped structure 2 is formed.

[0044] Specifically, the angle between the side surface and the bottom surface of the sponge airbag unit in the width direction is a right angle, or the angle between the side surface and the bottom surface of the sponge airbag unit in the width direction is an acute angle.

[0045] That is to say, when the angle between the side surface and the bottom surface of the sponge airbag monomer 11 in the width direction is an acute angle, the sponge airbag unit 1 formed by the sponge airbag monomer 11 is a concave structure on all sides, and the low-noise sponge airbag spring 3 is a wavy structure on all sides, further reducing the noise generation.

[0046] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0047] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
