Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to an airbag cushion and a mattress using the airbag cushion. Background Art

[0002] Existing airbag cushions include airbag strips arranged closely together in a front-to-back direction. These strips contain unit cells arranged in a straight line. The cells within a strip have top and bottom surfaces of equal height, resulting in a flat top and bottom surface for the airbag cushion, providing stable support for the user. Existing airbag strips are formed by welding multiple unit cells together. Each unit cell comprises multiple vertically stacked cavities, each enclosed by two sheets welded together. During the production of the airbag strip, the sheets must be sequentially welded to form the cavities, unit cells, and finally the strip. This results in a cumbersome process requiring numerous overlapping welding steps. The numerous welded areas increase the risk of damage and leakage, impacting the lifespan of the airbag strip. Furthermore, the cumbersome process lengthens the production time, reducing efficiency and impacting the user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides an airbag cushion and a mattress using the same, which are provided with an upper bag component and a lower bag component that are integrally processed and formed. The upper bag component and the lower bag component are stacked, fixedly bonded and adhered to form an airbag strip, which not only reduces the welding area, but also simplifies the processing steps and improves the user experience.

[0004] The present invention is implemented as follows: an airbag cushion includes an airbag strip, the airbag strip comprising an upper and lower strip-shaped, integrally injection-molded member, which are formed by vertically stacking and welding. The upper and lower strips are integrally formed and welded together to form the airbag strip. This reduces the weld area, effectively lowering the risk of damage and leakage, thus extending the life of the airbag cushion. It also simplifies the processing steps, improving assembly efficiency and enhancing the user experience by reducing the weld area. The upper and lower strips are injection-molded, facilitating mass production and ensuring surface sealing.

[0005] Preferably, the airbag strip is equipped with at least two interconnected, linearly arranged unit bladders. The upper bladder component includes at least two upper bladder bodies, and the lower bladder component includes lower bladder bodies corresponding to the upper bladder bodies. The upper and lower bladder bodies are vertically assembled to form the unit bladders. The upper bladders on the upper bladder component correspond to the lower bladders on the lower bladder component. The upper and lower bladders are stacked and welded to form the unit bladders, ensuring that the hardness of each unit bladder can be adjusted by adjusting the air pressure, thereby providing comfortable support for the user.

[0006] Preferably, an upper connecting piece is provided between the bottom surfaces of adjacent upper bladders, and a lower connecting piece is provided between the top surfaces of adjacent lower bladders. The upper and lower connecting pieces overlap and enclose to form an air passage, so that adjacent unit bladders are connected through the corresponding air passage. The upper connecting piece serves to connect adjacent upper bladders, and the lower connecting piece serves to connect adjacent lower bladders, ensuring that the relative positions of adjacent upper bladders and adjacent lower bladders are fixed, thereby ensuring that the upper and lower bladders can be vertically aligned and adhered to form a unit bladder. At the same time, the upper and lower connecting pieces also overlap and enclose to form an air passage, ensuring that adjacent unit bladders are connected through the air passage.

[0007] Preferably, the bottom surface of the upper connecting piece is provided with an upwardly protruding upper air path groove, and the top surface of the lower connecting piece is provided with a downwardly recessed lower air path groove. The upper and lower air path grooves are stacked and enclosed to form the air path channel. The upper and lower air path grooves are vertically stacked and enclosed to form the air path channel. This not only ensures that the cross-sectional profile of the air path channel meets the airflow conveying requirements, but also effectively limits the width of the air path channel, ensuring that the sides of the upper and lower connecting pieces have welding areas that meet the width requirements, thereby ensuring the reliability of the sealing along the air path channel.

[0008] Preferably, the bottom surface of the upper bag component and the top surface of the lower bag component are both provided with welding areas for fitting and welding, which not only ensures that the upper bag component and the lower bag component are reliably fixed, but also ensures that the unit bags are connected through the air passage.

[0009] Preferably, the welding area comprises linear regions disposed on the upper and lower connecting pieces on either side of the air passage. The two sides of the upper and lower connecting pieces adhere to each other to form the welding area, thereby forming an air passage between the upper and lower connecting pieces and ensuring that the air passage remains sealed along the entire length.

[0010] Preferably, the welding area comprises an annular region provided around the bottom periphery of the upper bladder body and the top periphery of the lower bladder body. The bottom periphery of the upper bladder body and the top periphery of the lower bladder body adhere to each other to form the welding area, thereby ensuring that the inner cavities of the upper and lower bladder bodies are interconnected, effectively maintaining the same air pressure, and also ensuring that the inner cavities of the unit bladders are isolated from the external space, facilitating air pressure regulation.

[0011] Preferably, the width of the welding area is A, A≥5mm, which not only improves the sealing reliability by increasing the width of the welding area and prevents damage and leakage, but also reduces the amount of welding operations by limiting the width of the welding area, thereby improving processing efficiency.

[0012] Preferably, the airbag strip includes at least two rows of unit airbags arranged front to back, and the adjacent rows of unit airbags are connected by air passage channels arranged front to back. By increasing the number of rows of unit airbags, the coverage area of the airbag strip is increased, which is convenient for forming a partition for synchronous air pressure adjustment, improves control convenience, reduces the number of airbag strips used in the airbag pad, and facilitates the assembly of the airbag pad.

[0013] Preferably, an air nozzle communicating with the unit airbag is provided at the end of the airbag strip. The airbag strip is connected to an external air source through the air nozzle, so that the air pressure in each unit airbag in the airbag strip can be synchronously adjusted, and thus the softness and hardness of the airbag strip can be freely adjusted, improving the use experience.

[0014] A mattress using the airbag pad includes a pad body, and the pad body includes an airbag pad and a limiting block that clamps and wraps the airbag pad. The limiting block plays a role in clamping, positioning and protecting the airbag pad, ensuring that the airbag pad is adjusted in softness and hardness by inflating and deflating at a preset position, and thus improving the use comfort of the pad body.

[0015] The beneficial effects of the present utility model are as follows: The upper airbag part and the lower airbag part are integrally processed and formed, and the upper airbag part and the lower airbag part are stacked, welded and adhered to form an airbag strip, which not only reduces the welding area, effectively reduces the risk of breakage and air leakage, prolongs the service life of the airbag pad, but also simplifies the processing steps, improves the assembly efficiency by reducing the welding area, and improves the use experience. The upper airbag part and the lower airbag part are injection molded, which is not only convenient for batch processing, but also ensures the wall surface sealing performance.

[0021] The following further illustrates the substantial features of the present utility model in conjunction with the drawings of the specification and the detailed embodiments.

[0022] Example 1:

[0023] This embodiment provides an airbag cushion.

[0024] As Figure 1 shown, an airbag cushion includes an airbag strip 1. The airbag strip 1 includes an upper bag member 3 and a lower bag member 4 that are in a long strip shape and integrally injection-molded. The upper bag member 3 and the lower bag member 4 are vertically stacked and welded to form the airbag strip 1. By setting the integrally processed upper bag member 3 and lower bag member 4, and the upper bag member 3 and the lower bag member 4 are adhesively formed into the airbag strip 1 through stacked welding, it not only reduces the welding area, effectively reduces the risk of breakage and air leakage, and prolongs the service life of the airbag cushion 13, but also simplifies the processing steps, and improves the assembly efficiency by reducing the welding area, thereby enhancing the user experience. The upper bag member 3 and the lower bag member 4 are injection-molded, which is not only convenient for batch processing, but also ensures the wall surface sealing performance.

[0025] In this embodiment, both the upper bag member 3 and the lower bag member 4 are integrally processed. The processing methods include injection molding and thermoforming, etc. It is not only convenient for batch processing, but also ensures that the wall surfaces of the upper bag member 3 and the lower bag member 4 remain sealed, and all should be regarded as the specific implementation manners of this embodiment.

[0026] In this embodiment, at least two unit bags 2 that are connected to each other and linearly arranged are provided on the airbag strip 1. The upper bag member 3 includes at least two upper bag bodies 5, and the lower bag member 4 includes lower bag bodies 6 corresponding to the upper bag bodies 5 one by one. The unit bag 2 is formed by stacking and fixedly connecting the upper bag body 5 on the upper bag member 3 and the corresponding lower bag body 6 on the lower bag member 4. When the upper bag member 3 including multiple upper bag bodies 5 is stacked with the lower bag member 4 including multiple lower bag bodies 6, multiple unit bags 2 can be simultaneously enclosed and formed, ensuring that the unit bags 2 on the airbag strip 1 are synchronously enclosed and formed, simplifying the assembly operation. The upper bag member 3 and the lower bag member 4 are fixedly connected by one-time welding, effectively reducing the welding workload and improving the assembly efficiency.

[0027] In this embodiment, an upper connecting piece 7 is provided between the bottom surfaces of adjacent upper bag bodies 5, and the upper connecting piece 7 is provided between any adjacent upper bag bodies 5, which not only ensures the relative position fixation between any group of adjacent upper bag bodies 5, but also ensures that an air passage 9 that can form a cross-connection is formed between any group of adjacent upper bag bodies 5 (as Figure 2As shown), it ensures that the air pressure in adjacent unit capsules 2 can be adjusted synchronously. A lower connecting piece 8 is provided between the top surfaces of adjacent lower capsules 6, and a lower connecting piece 8 is provided between any adjacent lower capsules 6, which not only ensures that the relative positions of any group of adjacent lower capsules 6 are fixed, but also ensures that any group of adjacent lower capsules 6 can form a bridging air channel 9, ensuring that the air pressure in adjacent unit capsules 2 can be adjusted synchronously. When the airbag strip 1 includes a single row of unit capsules 2, air channels 9 are provided between adjacent unit capsules 2, and the air channels 9 on the airbag strip 1 are all located on the same straight line, ensuring that the unit capsules 2 are connected in series through the air channels 9; when the airbag strip 1 includes multiple rows of unit capsules 2 in a matrix shape, the unit capsule 2 located in the middle of the airbag strip 1 has four cross-shaped air channels 9 distributed around it, ensuring that the unit capsule 2 is connected to each of the surrounding unit capsules 2 through the corresponding air channels 9, ensuring that the airflow from the air nozzle 12 can be quickly transported to the unit capsule 2, thereby ensuring that the overall hardness of the airbag strip 1 can be quickly adjusted.

[0028] In this embodiment, welding areas for fit welding are provided on the bottom surface of the upper bladder component 3 and the top surface of the lower bladder component 4. The upper bladder component 3 has a flat bottom surface, and the lower bladder component 4 has a flat top surface. The two are stacked and tightly welded to form the welding area, so that the upper bladder component 3 and the lower bladder component 4 can be sealed and fixed to form the airbag strip 1. Specifically, the welding area includes an annular area provided at the periphery of the bottom surface of the upper bladder body 5 and the periphery of the top surface of the lower bladder body 6. The upper bladder body 5 and the lower bladder body 6 are vertically stacked and enclosed to form the unit bladder 2; the welding area includes linear areas provided on the upper connecting piece 7 and the lower connecting piece 8 on both sides of the air passage 9. The upper connecting piece 7 and the lower connecting piece 8 are vertically stacked and enclosed to form the air passage 9.

[0029] In this embodiment, the upper connecting piece 7 and the lower connecting piece 8 are stacked and enclosed to form an air passage 9, allowing adjacent unit cells 2 to communicate through the corresponding air passages 9. The bottom surface of the upper connecting piece 7 is provided with an upwardly raised upper air passage groove 10, and the top surface of the lower connecting piece 8 is provided with a downwardly recessed lower air passage groove 11. The upper and lower air passage grooves 10 and 11 are stacked to enclose the air passage 9. The upper air passage groove 10 spans between adjacent upper cells 5, and the lower air passage groove 11 spans between adjacent lower cells 6. This ensures that the stacked upper and lower air passage grooves 10 and 11 form an air passage 9 with a circular cross-section, improving the deformation resistance of the air passage 9 and ensuring that the cross-sectional area of the air passage 9 meets the airflow flow requirements.

[0030] In this embodiment, the horizontal cross-sections of the upper bladder 5 and the lower bladder 6 are circular and include multiple vertically stacked and interconnected cavities, so that the upper bladder 5 and the lower bladder 6 have vertical telescopic deformation when inflated and deflated, thereby facilitating the adjustment of the softness and hardness of the unit bladder 2.

[0031] In this embodiment, the width of the welding area is A, where A ≥ 5 mm. By increasing the width of the welding area, the sealing reliability is improved, and by restricting the width of the welding area, the area of the welding area is reduced, thereby shortening the processing time and improving the production efficiency.

[0032] In this embodiment, the airbag strip 1 includes at least two rows of unit airbags 2 arranged in the front-rear direction. The adjacent rows of unit airbags 2 are connected by an air passage 9 arranged in the front-rear direction. The number of rows of unit airbags 2 in the airbag strip 1 and the number of unit airbags 2 in a single row can both be adjusted according to the usage requirements, and all should be regarded as specific implementation manners of this embodiment.

[0033] In this embodiment, an air nozzle 12 communicating with the unit airbag 2 is provided at the end of the airbag strip 1 (as Figure 3 shown). The unit airbags 2 on the airbag strip 1 are hermetically connected through the corresponding air passages 9. The airbag strip 1 is connected to an external air source through an air nozzle 12 provided at the end, so that the air pressure inside the airbag strip 1 can be adjusted through the air nozzle 12. The air nozzle 12 is at least one, and multiple air nozzles can also be dispersedly arranged according to needs to improve the inflation and deflation speed of each unit airbag 2 inside the airbag strip 1, and all should be regarded as specific implementation manners of this embodiment.

[0034] Embodiment Two:

[0035] Compared with Embodiment One, this embodiment provides a mattress.

[0036] As Figure 4 shown, the mattress includes a mattress body, and the mattress body includes an airbag mattress 13 and a limiting block 14 that clamps and wraps the airbag mattress 13. The limiting block 14 plays a role in clamping, positioning, and protecting the airbag mattress 13, ensuring that the airbag mattress 13 is adjusted in softness and hardness by inflating and deflating at a preset position, thereby improving the use comfort of the mattress body.

[0037] In this embodiment, through holes are provided on the limiting block 14, and the number and positions of the through holes are in one-to-one correspondence with the unit airbags 2 on the airbag mattress 13. During installation, the limiting block 14 wraps the airbag mattress 13, and the through holes are sleeved on the corresponding unit airbags 2, so that each unit airbag 2 is limited by the inner wall of the through hole, ensuring that the unit airbag 2 realizes vertical expansion and contraction under the guidance of the through hole, and then adjusts the softness and hardness by adjusting the air pressure, providing comfortable support for the user.

[0038] Other structures and effects of the airbag mattress in this embodiment are the same as those in Embodiment One, and will not be elaborated here.
