Description

Technical Field

[0001] This utility model belongs to the field of elastic pad technology, and is particularly applicable to elastic support products such as mattresses and seat cushions that require both support and comfort. It is especially targeted at scenarios where people who work at desks for long periods of time have high demands for spinal support and pressure distribution. Specifically, it relates to a woven bamboo fiber reinforced elastic pad. Background Technology

[0002] Mattresses and seat cushions are common elastic pads used in daily life; they are elastic support products used to support the human body.

[0003] As people's requirements for the quality of elastic pads gradually increase, their demands for the quality and function of elastic pads such as mattresses and seat cushions are also increasing. This is especially true for office workers and those who spend long hours at their desks, for whom a good elastic pad is particularly important.

[0004] Bamboo fiber, as the fifth major natural fiber after cotton, linen, silk, and wool, has properties such as moisture absorption and breathability, antibacterial and antimicrobial properties, and is widely used in the processing of elastic pads such as mattresses.

[0005] For example, in the prior art, the Chinese utility model patent CN204838774U, after being authorized and published, discloses a "bamboo fiber mattress", which includes, from top to bottom, a first fabric layer, a first latex layer, a bamboo fiber layer, a spring layer, a second latex layer, and a second fabric layer; the first fabric layer is located at the top of the bamboo fiber mattress and is in contact with the human body; the bamboo fiber layer is composed of bamboo fibers, the spring layer includes multiple springs, and the multiple springs are independent of each other; the first latex layer and the second latex layer are composed of latex.

[0006] Bamboo fiber mattresses in the prior art, including those mentioned above, can meet general usage needs, but in actual use, the combination of bamboo fiber and rigid support structure (such as independent springs) generally has the problem of "poor force matching between the fiber layer and the support layer (easy to cause local collapse under force)". Especially for users with higher weight, local pressure concentration can easily lead to wear or breakage of the fiber layer.

[0007] Therefore, there is an urgent need for an enhanced elastic pad that can take into account the natural properties of bamboo fiber, improve softness, and optimize the stress distribution of the support structure. Utility Model Content

[0008] To address the aforementioned problems in the existing technology, this utility model provides a woven bamboo fiber reinforced elastic mat. The purpose is to overcome the problems of existing bamboo fiber elastic mats, such as "hard feel, poor bending resistance, uneven local stress, and easy tearing." This woven bamboo fiber reinforced elastic mat enhances softness through composite fiber weaving, optimizes stress distribution through layered support and arrayed elastic units, and retains the moisture absorption, breathability, and antibacterial properties of bamboo fiber.

[0015] As a preferred technical solution of this utility model, the bamboo fiber woven layer also includes plant fibers, and the bamboo fiber filaments, plant fibers and elastic synthetic fibers are interwoven to form the three-dimensional mesh structure.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-4 The present invention provides the following technical solution: a woven bamboo fiber reinforced elastic pad, including an inner core body 2 and a covering structure 1 wrapped around the inner core body 2. The inner core body 2 includes: a composite fiber three-dimensional reinforcement layer, at least two spaced support and bearing layers, multiple elastic support units, and a buffer layer 24.

[0036] Furthermore, by Figures 1-4 As shown in this embodiment, the composite fiber three-dimensional reinforcement layer is formed by interlacing natural fibers and synthetic fibers to create a three-dimensional mesh structure with three-dimensional support capabilities. The support and bearing layer is disposed on the bottom side of the composite fiber three-dimensional reinforcement layer. The elastic support units are regularly distributed in an array between at least two support and bearing layers. The buffer layer 24 is fixedly connected to the bottom side of the support and bearing layer located at the bottom. With the above scheme, when external pressure is applied to the elastic pad during use, the pressure is first uniformly borne by the covering structure 1 and transmitted to the inner core body 2.

[0037] The composite fiber three-dimensional reinforcement layer, with its three-dimensional network structure, utilizes the toughness of natural fibers and the high strength of synthetic fibers to disperse the initial pressure in multiple directions. When subjected to force, the natural fibers undergo micro-deformation to absorb some energy, while the synthetic fibers transmit the pressure evenly to the lower structure through the rigid skeleton, forming the first pressure buffer barrier.

[0038] The supporting load-bearing layer located at the bottom of the composite fiber three-dimensional reinforcement layer transforms the dispersed pressure transmitted from the upper layer into a uniformly distributed planar load. When the pressure is transmitted to the elastic support unit between the two supporting load-bearing layers, the regularly arrayed elastic units (such as helical springs or elastic columns) undergo axial compression deformation. The impact energy is absorbed through the elastic deformation of the material, while the geometric constraints of the array structure are used to avoid excessive deformation, thus achieving dynamic balance of loads in different directions. For example, under vertical pressure, the elastic units store potential energy through compression. Under lateral shear force, the mutual restraint of the array structure can suppress lateral displacement and maintain the overall structural stability.

[0039] The bottommost support layer transfers the load buffered by the elastic support unit to the buffer layer 24, further absorbing high-frequency vibration energy, while consuming residual kinetic energy through internal material friction.

[0040] In summary, this invention enhances softness through the interweaving of natural and synthetic fibers, optimizes stress distribution through layered support and arrayed elastic units, improves softness and bending resistance, optimizes local stress uniformity, and enhances cushioning and support performance, while retaining the moisture-wicking, breathable, and antibacterial properties of bamboo fiber, thus improving user comfort. It is suitable for users of different weights and can be extended to mattresses, seat cushions, and other elastic pads, making it highly practical.

[0041] Optionally, by Figures 1-4 As shown in this embodiment, the composite fiber three-dimensional reinforcement layer is a bamboo fiber woven layer 21, and the natural fiber in the bamboo fiber woven layer 21 is bamboo fiber filament 211, and the synthetic fiber is elastic synthetic fiber. After adopting the above scheme, when the composite fiber three-dimensional reinforcement layer is specifically a bamboo fiber woven layer 21, it is formed by the interlacing of bamboo fiber filament 211 and elastic synthetic fiber to form a three-dimensional mesh support structure.

[0042] Under external load, bamboo fiber 211, thanks to the helical structure of natural cellulose molecular chains, first absorbs low-frequency stress through micro-slippage between fiber bundles. The natural waxy layer distributed on its surface can reduce frictional loss between fibers and extend fatigue life. Meanwhile, elastic synthetic fibers (such as polyester elastomers or spandex fibers) provide initial stiffness support through their high elastic modulus.

[0043] The natural bamboo quinone component contained in bamboo fiber filament 211 can inhibit bacterial growth on the contact surface between the coating structure 1 and the inner core body 2 during long-term use.

[0044] Preferably, by Figures 1-4As shown in this embodiment, the bamboo fiber woven layer 21 also includes plant fibers. The bamboo fiber filaments 211, plant fibers and elastic synthetic fibers are interwoven to form a three-dimensional mesh structure. After adopting the above solution, when an external load is applied, the bamboo fiber filaments 211 first resist tensile deformation through axial stiffness, while the plant fibers undergo micro-bending when the nodes are bent, and dissipate impact energy through inter-fiber friction, thus avoiding the breakage of a single bamboo fiber filament 211 due to stress concentration.

[0045] Optionally, by Figures 1-4 As shown in this embodiment, the plant fiber is cotton fiber 212 and the elastic synthetic fiber is spandex fiber 213. After adopting the above scheme, when in use, cotton fiber 212 can significantly improve the softness and skin-friendliness of the woven fabric, improve the stiffness of pure bamboo fiber spinning, and at the same time retain the antibacterial and moisture-absorbing advantages of bamboo fiber.

[0046] The high elasticity of spandex fiber 213 can compensate for the lack of elasticity in bamboo fiber.

[0047] Optionally, by Figures 1-4 As shown in this embodiment, the porosity of the three-dimensional mesh structure is 40%-70% and the thickness is 1-6cm. After adopting the above scheme, the porosity and thickness of the three-dimensional mesh structure of the bamboo fiber woven layer 21 can be controlled according to different usage scenarios. For example, in low porosity scenarios (porosity 40%-50%, thickness 1-3cm), it is suitable for scenarios that require stable support, such as lumbar support, to avoid collapse after sitting for a long time.

[0048] Medium to high porosity (porosity 50%-70%, thickness 3-6cm), suitable for dynamic cushioning applications such as mattresses and seat cushions.

[0049] Optionally, by Figures 1-3 As shown in this embodiment, the elastic support unit is a spring 23 wrapped with non-woven fabric. With the above solution, when the pressure is transmitted to the spring 23 between the two support layers, the regularly arrayed spring 23 undergoes axial compression deformation. The impact energy is absorbed through the elastic deformation of the material, and the geometric constraints of the array structure are used to avoid excessive deformation, thereby achieving dynamic balance of loads in different directions. For example, under vertical pressure, the spring 23 stores potential energy through compression. Under lateral shear force, the mutual restraint of the array structure can suppress lateral displacement and maintain the overall structural stability.

[0050] Optionally, by Figures 1-3As shown in this embodiment, the buffer layer 24 is at least one of latex and polyurethane foam, and the top and bottom surfaces of the buffer layer 24 are provided with anti-slip protrusions 241 arranged in a regular array. After adopting the above solution, when in use, the viscoelastic network of natural latex undergoes nonlinear large deformation under pressure, and the impact energy is consumed through the internal friction of molecular chain segments.

[0051] Polyurethane foam undergoes collapse deformation under pressure, absorbing high-frequency vibration energy through the bending and fracture of the pore walls.

[0052] Anti-slip protrusion 241 provides initial contact pressure during static support, enhancing interfacial friction.

[0053] Optionally, by Figure 1 As shown, in this embodiment, the covering structure 1 includes: two surface layers 11 with first ventilation holes 111 on the top and bottom, and a binding edge 12 connected between the two first ventilation holes 111 by a connecting component 13. The binding edge 12 has a second ventilation hole 121. After adopting the above solution, when in use, the upper and lower surface layers 11 are made of skin-friendly knitted fabric, such as bamboo fiber blended fabric.

[0054] When the human body comes into contact with the surface layer 11, the air in the pressure area (carrying body surface heat and sweat) is squeezed out through the first vent 111.

[0055] The edging 12 is made of elastic woven fabric, and the second ventilation holes 121, which are evenly distributed around the circumference, connect the internal and external environments, and form an annular ventilation belt on the side of the elastic pad to prevent hot and humid air from lingering in the corners.

[0056] Optionally, by Figure 1 As shown in this embodiment, the connecting component 13 is a zipper or a sewing thread. With the above solution, the appropriate connection method can be selected for different usage scenarios during use.

[0057] When quick disassembly and washing are required, zippers are the preferred choice.

[0058] Preferably, by Figures 1-3 As shown in this embodiment, the supporting layer is a rigid sponge layer 22. The rigid sponge layer 22 has third vent holes 221 arranged in a regular array. Activated carbon particles 222 are dispersed in the rigid sponge layer 22. With the above solution, the closed-cell structure of the rigid sponge provides stable support stiffness during use. When the spring 23 is compressed, the single-point load is diffused through the rigid sponge layer 22 matrix to the surrounding area of ​​the third vent holes 221.

[0059] The bottom fiber bundles of the bamboo fiber woven layer 21 form a mechanical interlock with the micropores on the surface of the rigid sponge layer 22, and the interfacial bonding force is generated through the hot pressing process.

[0060] The third vent 221 directly connects the mesh pores of the upper bamboo fiber woven layer 21 with the gap between the lower elastic support unit (spring 23), forming a longitudinal air guiding channel.

[0061] Components not described in detail in this article are existing technologies.

[0062] The working principle and usage process of this utility model: When the elastic pad of this utility model is used, when external pressure is applied to the elastic pad, the pressure is first uniformly borne by the covering structure 1 and transmitted to the inner core body 2.

[0063] The composite fiber three-dimensional reinforcement layer, with its three-dimensional mesh structure, utilizes the toughness of natural fibers and the high strength of synthetic fibers to disperse the initial pressure in multiple directions. When subjected to force, the natural fibers undergo micro-deformation to absorb some energy, while the synthetic fibers transmit the pressure evenly to the lower structure through the rigid skeleton, forming the first pressure buffer barrier.

[0064] The supporting load-bearing layer located at the bottom of the composite fiber three-dimensional reinforcement layer transforms the dispersed pressure transmitted from the upper layer into a uniformly distributed planar load. When the pressure is transmitted to the elastic support unit between the two supporting load-bearing layers, the regularly arrayed elastic units (such as helical springs or elastic columns) undergo axial compression deformation. The impact energy is absorbed through the elastic deformation of the material, while the geometric constraints of the array structure are used to avoid excessive deformation, thus achieving dynamic balance of loads in different directions. For example, under vertical pressure, the elastic units store potential energy through compression. Under transverse shear force, the mutual restraint of the array structure can suppress lateral displacement and maintain the overall structural stability.

[0065] The bottommost support layer transfers the load buffered by the elastic support unit to the buffer layer 24, further absorbing high-frequency vibration energy, while consuming residual kinetic energy through internal material friction.

[0066] In summary, this invention enhances softness through the interweaving of natural and synthetic fibers, optimizes stress distribution through layered support and arrayed elastic units, improves softness and bending resistance, optimizes local stress uniformity, and enhances cushioning and support performance, while retaining the moisture-wicking, breathable, and antibacterial properties of bamboo fiber, thus improving user comfort. It is suitable for users of different weights and can be extended to mattresses, seat cushions, and other elastic pad applications, making it highly practical.

[0067] The bamboo fiber woven layer 21 can be made using common weaving techniques such as plain weave, twill weave, or spiral weave. For example, spiral weave is formed by winding or interlacing bamboo fiber filaments 211 in a spiral trajectory to create a three-dimensional structure. The specific process can be found in existing technologies and will not be elaborated further in this article.

[0068] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
