Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a strip-shaped airbag and mattress. Background Technology

[0002] Existing strip-shaped airbag mattresses include a mattress body, a support layer within the mattress body, and an outer cover enclosing the support layer. The support layer contains a support bladder assembly and a control box for adjusting the air pressure within the support bladder assembly, thereby adjusting the mattress's firmness to meet the diverse needs of users. Existing support bladder assemblies include strip-shaped airbags arranged side-by-side and joined to form a support surface for the user. Existing strip-shaped airbags are all single-layer TPU structures, formed by welding and bonding multiple sheets of material together. Because the TPU material of the strip-shaped airbags generates noise due to friction during inflation / deflation or deformation under stress, it affects the user's sleep and impacts the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a strip-shaped airbag and mattress with good noise reduction effect. The airbag body is formed by processing end face sheets and edge sheets with a multi-layer structure of velvet noise reduction layer, so that when the surfaces of adjacent airbag bodies come into contact, the velvet noise reduction layer can reduce the noise generated by friction, reduce the impact on the user's sleep, and improve the user experience.

[0004] This invention achieves its purpose through the following method: a strip-shaped airbag with good noise reduction effect, comprising a long strip-shaped airbag body formed by bonding end face sheets and edge sheets together. Both the end face sheets and edge sheets have the same multi-layer structure, including a TPU layer, a nylon layer, and a fleece noise-reducing layer stacked and bonded sequentially. The fleece noise-reducing layer is located on the outer surface of the airbag body to reduce noise generated by friction between adjacent airbag bodies. The airbag body is formed using end face sheets and edge sheets with a multi-layer structure and fleece noise-reducing layer, allowing the fleece noise-reducing layer to reduce friction noise when adjacent airbag surfaces come into contact, thus reducing the impact on the user's sleep and improving the user experience. Furthermore, the TPU layer facilitates welding and bonding between the end face sheets and edge sheets, and the nylon layer enhances the structural strength of the end face sheets and edge sheets.

[0005] Preferably, the TPU layer, nylon layer, and fleece noise-reducing layer have the same outline, ensuring that the layered structure of each area of ​​the end face sheet and the edge sheet is identical. The TPU layer, nylon layer, and fleece noise-reducing layer are matched, stacked, and bonded together to ensure that each area of ​​the end face sheet and the edge sheet has the same multi-layered structure, facilitating mass production and cutting as needed.

[0006] Preferably, the ends of the edging sheet are folded outwards to form flanges, and the end face sheet covers the upper and lower ends of the edging sheet. The edging sheet is bonded to the TPU layer of the end face sheet through the folded TPU layer. By setting the flanges, the contact area between the edging sheet and the end face sheet is increased, thereby improving sealing performance and connection reliability.

[0007] Preferably, the edging sheet comprises two elongated substrates of the same length, with corresponding edges of adjacent substrates aligned and bonded together using a TPU sheet. The two sides of the TPU sheet are adhered to the TPU layers of the corresponding edges of the substrates. By using two substrates of the same size bonded together to form the edging sheet, the size requirements of the substrates are reduced, facilitating processing. Furthermore, limiting the number of substrates reduces the length of the welding area, thereby ensuring sealing performance. The flat, spliced ​​joint of the corresponding edges of the substrates and the welding bond using the TPU sheet ensures that the edging sheet formed by the substrates has a uniform perimeter and also ensures good sealing between the corresponding edges of the substrates by increasing the width of the contact area between the TPU sheet and the substrate.

[0008] Preferably, the edging sheet includes two parallel linear segments and an arc segment spanning the corresponding ends of the linear segments, and the TPU sheet is disposed at the junction of the linear segments and the arc segment.

[0009] Preferably, the length of the TPU sheet corresponds to the length of the substrate edge, so that the TPU sheet completely seals the gap between the corresponding edges of adjacent substrates. This ensures that the TPU sheet completely covers the gap between the edges of adjacent substrates without the TPU sheet being exposed at the edge of the edging sheet, ensuring that the edging sheet can effectively adhere and connect with the end face sheet. The TPU layer is located on the inner wall of the edging sheet, allowing the TPU sheet to adhere to and be welded to the inner wall of the edging sheet.

[0010] Preferably, horizontally arranged tie rods are used to bridge the linear segments. The width of the tie rods is smaller than the width of the end sheet, so that the capsule is funnel-shaped with the center contracting inward. The tie rods pull and shape the center of the capsule, ensuring that the center of the capsule sidewall is concave inward, effectively reducing friction between the corresponding sidewalls of adjacent capsules, thereby reducing noise.

[0011] Preferably, the length of the tie rod is less than the length of the linear segment, so that the end edge of the tie rod is misaligned with the TPU sheet. By limiting the length of the tie rod, it is ensured that it can be smoothly assembled into the edging sheet. The misalignment of the end edge of the tie rod with the TPU sheet prevents air leakage in local areas of the edging sheet due to repeated welding, thus ensuring the airtightness of the bladder.

[0012] Preferably, the bladder is divided into a vertically separated upper cavity and a lower cavity. A through-hole is formed between the edge of the reinforcing rib and the arc segment. The upper and lower cavities are connected through the through-hole and share an air nozzle located at the bottom of the bladder's end face. The upper and lower cavities improve the bladder's shape stability, ensuring it maintains a preset contour. This effectively supports the user and prevents friction between adjacent cavities, effectively eliminating noise. The upper and lower cavities are vertically stacked and interconnected. This allows for adjusting the bladder's height by utilizing the deformation of each cavity, thereby adjusting its vertical stiffness. Furthermore, the shared air nozzle ensures synchronized air pressure adjustment within both cavities.

[0013] A mattress includes a support layer and an outer cover enclosing the support layer. The support layer contains strip-shaped air chambers arranged side-by-side and joined together at their top surfaces to form a flat support surface. The side-by-side arrangement of the air chambers ensures that their top surfaces are at the same height and joined together to form a flat support surface. This effectively improves support comfort and allows for control of the firmness of the support surface by adjusting the air pressure within the air chambers, meeting diverse user needs and enhancing the user experience.

[0014] The beneficial effects of this utility model are as follows: The capsule is formed by processing the end face sheet and the surrounding sheet with a multi-layer structure of velvet noise reduction layer, so that when the surfaces of adjacent capsules come into contact, the noise generated by friction can be reduced by the velvet noise reduction layer, thereby reducing the impact on the user's sleep and improving the user experience.

[0023] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] This embodiment provides a strip-shaped airbag with good noise reduction effect.

[0026] like Figure 1 and 2 The illustrated strip-shaped airbag with good noise reduction effect includes a long strip-shaped airbag 1. The airbag 1 is formed by bonding an end face sheet 3 and an edge sheet 4 together. Both the end face sheet 3 and the edge sheet 4 have the same multi-layer structure, including a TPU layer 13, a nylon layer 14, and a fleece noise-reducing layer 15 stacked and bonded sequentially. The fleece noise-reducing layer 15 is located on the outer surface of the airbag 1 to reduce the noise generated by friction between adjacent airbags 1. The airbag 1 is formed by processing the end face sheet 3 and the edge sheet 4 with the multi-layer structure of the fleece noise-reducing layer 15, so that when the surfaces of adjacent airbags 1 come into contact, the fleece noise-reducing layer 15 can reduce the noise generated by friction, reduce the impact on the user's sleep, and improve the user experience.

[0027] In this embodiment, the end face sheet 3 and the edge sheet 4 are both formed by cutting and processing whole raw material sheets, so that the TPU layer 13, nylon layer 14 and fleece noise reduction layer 15 on the end face sheet 3 and the edge sheet 4 have the same outline and thus have the same functional characteristics.

[0028] In practice, the single raw material sheet has a large size and regular outline, effectively reducing the difficulty of stacking and processing the raw material sheet. The raw material sheet includes a TPU layer 13, a nylon layer 14, and a fleece noise reduction layer 15 stacked sequentially. The TPU layer 13 becomes adhesive after heating, which facilitates welding and bonding the end face sheet 3 and the edge sheet 4. The nylon layer 14 has good structural strength and plays a shaping role for the end face sheet 3 and the edge sheet 4, preventing deformation of the end face sheet 3 and the edge sheet 4 due to tension, and ensuring that the capsule 1 has a constant outline. The fleece noise reduction layer 15 has a soft fleece attached to its surface, which can not only use the space inside the fleece to impede the transmission of noise, but also reduce the noise of the capsule 1 when it is in contact with friction through deformation, thus playing a role in noise reduction.

[0029] In actual operation, the end face sheet 3 covers the upper and lower ports of the surrounding sheet 4. The end face sheet 3 and the surrounding sheet 4 are bonded and sealed together by the TPU layer 13 in corresponding areas, so that the end face sheet 3 and the surrounding sheet 4 form the capsule 1 through bonding. The port of the surrounding sheet 4 is turned outward to form a flange. The surrounding sheet 4 is bonded and fixed to the TPU layer 13 of the end face sheet 3 through the flanged TPU layer 13. The TPU layer 13 of the surrounding sheet 4 is located on its inner sidewall. The surrounding sheet 4 is turned outward to form a flange. The flanged TPU layer 13 is set towards the end face sheet 3. The end face sheet 3 is towards the surrounding sheet 4 through the TPU layer 13, so that the end face sheet 3 and the surrounding sheet 4 are bonded together through the TPU layer 13.

[0030] In this embodiment, the edging sheet 4 includes two long strip-shaped substrates 17 of the same length (e.g., Figure 3 As shown, the corresponding edges of adjacent substrates 17 are aligned and bonded together by a TPU sheet 16. The two sides of the TPU sheet 16 are bonded to the TPU layer 13 of the corresponding edge of the substrate 17. The length of the TPU sheet 16 corresponds to the length of the edge of the substrate 17, ensuring that the TPU sheet 16 completely seals the gap between the corresponding edges of adjacent substrates 17. The edging sheet 4 is formed by joining two substrates 17 end-to-end. The corresponding edges of the substrates 17 are flatly joined and bonded together by the TPU sheet 16, ensuring that the perimeter of the edging sheet 4 is fixed and twice the length of the substrate 17. The two sides of the TPU sheet 16 are respectively stacked on the corresponding edge of the substrate 17. By increasing the width of the bonding area between the TPU sheet 16 and the edge of the substrate 17, the connection reliability and sealing performance are improved. The substrates 17 have the same size, which facilitates batch cutting and processing and effectively ensures that the perimeter of the edging sheet 4 is fixed, thus obtaining a capsule 1 with uniform dimensions.

[0031] In this embodiment, a horizontally arranged tie rod 2 spans between the linear segments 5. The width of the tie rod 2 is smaller than the width of the end sheet 3, so that the capsule 1 is funnel-shaped, tapering inward from the center. The edging sheet 4 includes two parallel linear segments 5 and an arc segment 6 spanning between the corresponding end edges of the linear segments 5. The TPU sheet 16 is disposed at the junction of the linear segments 5 and the arc segment 6. The length of the tie rod 2 is less than the length of the linear segment 5, so that the end edge of the tie rod 2 is misaligned with the TPU sheet 16. The side edge of the tie rod 2 is laid along the length direction of the linear segment 5, so that the side edge of the tie rod 2 is misaligned with the TPU sheet 16 (e.g., ...). Figure 5 As shown), this prevents stress concentration in local areas of the edging sheet 4 due to the interlaced welds, effectively preventing damage and air leakage in that area and improving the sealing performance of the bladder 1.

[0032] In this embodiment, the upper cavity 7 and the lower cavity 8 are connected by a through hole 12 located at the end of the bladder body 1 (e.g., Figure 4As shown, this ensures that the upper cavity 7 and lower cavity 8 can share the same air nozzle 9 and achieve synchronized air pressure regulation, ensuring that the bladder 1 can rise and fall vertically and reduce the tilt amplitude, providing vertical force for the user. The side edge of the tie 2 is continuously bonded to the centerline of the linear segment 5 horizontally, so that the upper cavity 7 and lower cavity 8 have the same height, ensuring that the upper cavity 7 and lower cavity 8 have the same mechanical performance, thereby improving the deformation synchronization of the top and bottom of the bladder 1.

[0033] In this embodiment, the length of the tie rod 2 is less than the length of the capsule 1. The upper cavity 7 and the lower cavity 8 are connected through the through hole 12 at the end of the capsule 1, ensuring that the tie rod 2 can completely cover the linear segment 5. The width limiting effect on the middle part of the capsule 1 is improved by increasing the welding adhesion length. The through hole 12 for connecting the upper cavity 7 and the lower cavity 8 can also be formed between the end edge of the tie rod 2 and the arc segment 6, ensuring that the air pressure in the upper cavity 7 and the lower cavity 8 is adjusted synchronously. The synchronization is improved by increasing the cross-sectional area of ​​the through hole 12.

[0034] In this embodiment, the bottom end face of the capsule 1 is provided with an air nozzle 9 (e.g., ...) that communicates with the outside. Figure 6 (As shown). The nozzle 9 is independently machined and assembled onto the bladder body 1, facilitating machining and assembly. A mounting hole is opened at the bottom of the arc segment 6, through which the nozzle 9 passes and is welded and bonded, ensuring that the nozzle 9 is fixedly connected to the bladder body 1 and communicates with the lower cavity 8, thereby enabling synchronous adjustment of the air pressure in the upper cavity 7 and the lower cavity 8.

[0035] Example 2:

[0036] Compared to Embodiment 1, this embodiment provides a mattress.

[0037] like Figure 7 The mattress shown includes a support layer 10 and an outer cover 11 that surrounds the support layer 10. The support layer 10 contains strip-shaped airbags arranged side-by-side and joined together at their top surfaces to form a flat support surface. The side-by-side arrangement of the airbags ensures that their top surfaces are at the same height and joined together to form a flat support surface. This effectively improves support comfort and allows for control of the firmness of the support surface by adjusting the air pressure within the airbags, meeting diverse user needs and enhancing the user experience.

[0038] In this embodiment, the support bladder assembly is located in the middle of the support layer 10, which can provide effective support for the user and reduce production costs by limiting the number of bladders 1.

[0039] In this embodiment, the top surface of the support layer 10 is provided with a massage component. The massage component generates vertical deformation by inflating and deflating air, thereby applying a massage force to the user.

[0040] In this embodiment, the support layer 10 is provided with a device section, and the device section is provided with a control box. The air pressure of the support bladder group and the massage component is adjusted through the control box to obtain the corresponding functions and improve the user experience.

[0041] In this embodiment, the outer cover 11 can completely wrap the support layer 10, which not only protects the support layer 10, but also makes it easy to disassemble and replace the outer cover 11 and clean it, thus improving the user experience.

[0042] The other structures and effects of the strip-shaped airbag described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
