Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to an airbag cushion and mattress. Background Technology

[0002] Existing airbag cushions include side-by-side airbag strips, each strip comprising airbag bodies arranged in a straight line. The airbag cushion is formed by matrix-assembling the airbag bodies. During processing, firstly, cut sheets are stacked and welded together to form airbag bodies; then, the airbag bodies are welded side-by-side to form airbag strips; finally, the side-by-side airbag strips are welded together to form the airbag cushion. This entire process involves repeatedly welding and assembling the cut sheets, requiring the cutting of numerous sheets and multiple welding and bonding operations to form the required airbag cushion. This increases the workload of welding and bonding, affecting production efficiency and processing costs. Furthermore, the numerous welding and bonding areas can easily create leakage points, thus affecting the airbag cushion's sealing performance and user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an easily processed airbag cushion and mattress. The airbag pieces formed by integral injection molding are assembled to form an upper and lower piece. Adjacent airbag pieces and the assembled upper and lower pieces are welded together in one go, effectively reducing the number of bonding processes, improving processing efficiency, enhancing sealing, and thus improving the user experience.

[0004] This invention is achieved through the following method: a conveniently processed airbag cushion, comprising an upper piece and a lower piece, both of which are formed by splicing together elongated, integrally injection-molded airbag pieces. The vertically stacked upper and lower pieces are integrally bonded together to reduce the number of bonding processes. The upper and lower pieces are formed by splicing together the integrally injection-molded airbag pieces, and adjacent airbag pieces, as well as the assembled upper and lower pieces, are integrally welded together in a single process. This effectively reduces the number of bonding processes, improving processing efficiency and reducing processing costs. Furthermore, by using integrally injection-molded airbag pieces instead of the original cut sheets, welding is not required starting from the airbag body, effectively reducing the welding area and thus improving sealing and user experience.

[0005] Preferably, the capsule pieces have identical structures, and are arranged side-by-side to form upper and lower pieces that can be flipped and switched. Adjacent capsule pieces, as well as upper and lower pieces, are fixed together by a single adhesive bonding process. The identical capsule pieces can be processed using the same mold, effectively increasing production output and reducing processing costs. The capsule pieces are flipped and switched to form upper and lower pieces, improving production efficiency by sharing capsule pieces and preventing assembly errors due to diverse raw material types, thus effectively reducing waste. The single adhesive bonding between adjacent capsule pieces, as well as between upper and lower pieces, eliminates the need for sequential assembly and welding of sheets into the capsule body, capsule strips, and airbag cushion, simplifying the structure and effectively improving processing efficiency.

[0006] Preferably, the capsule includes plenum grooves evenly spaced along its length and buffer grooves at its ends, with venting grooves bridging adjacent plenum grooves and between buffer grooves and adjacent plenum grooves. The plenum grooves, buffer grooves, and venting grooves are all formed integrally during injection molding, which facilitates processing and allows the capsule to be used after being assembled and welded.

[0007] Preferably, the bladder groove is cylindrical, which facilitates demolding after injection molding and ensures that the bladder formed by assembling the bladder groove has good vertical support performance.

[0008] Preferably, the groove wall of the bladder is formed into a wave-like shape that can expand and fold along its axis by radial reciprocating bending. The foldable groove wall effectively increases the expansion and contraction range of the groove wall, thereby meeting the needs of regulating the air pressure inside the bladder during inflation and deflation, and improving the adjustment range of softness and hardness.

[0009] Preferably, one side edge of the airbag is provided with equidistant connecting pieces, and the airbag is bonded and fixed to adjacent airbags through the connecting pieces. Adjacent airbags are stacked with corresponding connecting pieces, which facilitates welding and bonding, ensures that the relative positions of adjacent airbags are fixed, and prevents the airbag from becoming unusable due to displacement of the airbags during bonding.

[0010] Preferably, the capsule pieces are flipped along their width and assembled to form a lower or upper piece. The upper and lower pieces are vertically stacked and bonded together, so that the capsule groove, buffer groove, and venting groove are connected to form a capsule cavity, a buffer cavity, and a venting tube, respectively. The venting tube is arranged along the length of the capsule piece and connects the capsule cavities and buffer cavities along its path. This facilitates the one-time bonding and molding of the capsule strips and allows the capsule groove, buffer groove, and venting groove to be formed during injection molding, effectively reducing processing difficulty. When the capsule pieces are stacked and welded together, the corresponding capsule grooves are connected to form independent inflatable and deflated capsule cavities. The buffer grooves located at the ends of the capsule pieces are bonded together to form buffer cavities, and the venting grooves are bonded together to form venting tubes.

[0011] Preferably, the upper and lower pieces form a connection area around the bladder cavity, buffer cavity, and ventilation cavity. The upper and lower pieces are vertically stacked and bonded together through the corresponding connection area for sealing. The upper and lower pieces are bonded and welded together through the corresponding connection area, which not only ensures the sealed connection of the bladder cavity, buffer cavity, and ventilation tube, but also improves the sealing reliability by increasing the width of the connection area.

[0012] Preferably, the buffer chamber is arranged linearly along one side of the airbag cushion. A through hole is formed on the top or bottom wall of the buffer chamber for inserting and connecting an air nozzle. The inner end of the air nozzle is inserted into the through hole and communicates with the buffer chamber, while the outer end protrudes from the side edge of the airbag cushion and communicates with an external air source. The buffer chamber serves to connect the airbag cavity and the air nozzle. The air nozzle is inserted into the buffer chamber through the through hole, allowing the air nozzle to adjust the air pressure inside the airbag cavity.

[0013] Preferably, the inner end of the air nozzle extends to form a sealing sheet that can fit against the periphery of the through hole. The sealing sheet adheres to the periphery of the through hole, effectively improving the sealing performance between the air nozzle and the through hole and preventing air leakage at the connection between the through hole and the air nozzle.

[0014] A mattress includes a mattress body comprising an airbag pad, a support layer fitted over the airbag pad, a perimeter surrounding the support layer, and a comfort layer stacked on top of the airbag pad. The support layer has slots for vertically inserting the airbag pads. The airbags are inserted into corresponding slots, allowing the support layer and airbag pad to overlap and connect. The slots provide horizontal restraint for each airbag, ensuring vertical adjustment through inflation and deflation of the airbags.

[0015] The beneficial effects of this utility model are as follows: The upper and lower pieces are formed by assembling the bladder pieces through integral injection molding, and the adjacent bladder pieces and the assembled upper and lower pieces are welded together in one go, which effectively reduces the number of bonding processes, improves processing efficiency, and effectively reduces processing costs. In addition, by using the integrally injection molded bladder pieces to replace the original cut sheets, there is no need to start welding from the bladder body, which effectively reduces the welding area, thereby improving sealing and enhancing the user experience.

[0024] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] This embodiment provides an airbag cushion that is easy to process.

[0027] like Figure 1 and 2 The airbag shown includes an upper piece 1 and a lower piece 2. Both the upper piece 1 and the lower piece 2 are formed by assembling integrally injection-molded elongated airbag pieces 3. The vertically stacked upper piece 1 and lower piece 2 are fixed together by integral bonding to reduce the number of bonding processes. The upper piece 1 and lower piece 2 are formed by assembling the airbag pieces 3 formed by integral injection molding. Adjacent airbag pieces 3 and the assembled upper piece 1 and lower piece 2 are integrally welded and bonded in one go, effectively reducing the number of bonding processes. This improves processing efficiency and effectively reduces processing costs. Furthermore, by using integrally injection-molded airbag pieces 3 instead of the original cut sheets, there is no need to start welding from the airbag body, effectively reducing the welding area, thereby improving sealing performance and enhancing the user experience.

[0028] In this embodiment, the capsule pieces 3 have identical structures. The capsule pieces 3 are arranged side-by-side and assembled to form an upper piece 1 and a lower piece 2 that can be flipped and switched. Adjacent capsule pieces 3, and upper piece 1 and lower piece 2, are fixed together by a single adhesive bonding. Both the upper piece 1 and lower piece 2 are formed by splicing capsule pieces 3 with the same structure. Multiple capsule pieces 3 are assembled side-by-side to form the upper piece 1, and a corresponding number of capsule pieces 3 are assembled side-by-side to form the lower piece 2. The upper piece 1 and lower piece 2 are vertically stacked and bonded together by overall welding. This welding bonding between adjacent capsule pieces 3 effectively reduces the number of welding bonding operations and improves sealing performance by reducing weld seams. The capsule pieces 3 are flipped along their width direction and assembled to form either the lower piece 2 or the upper piece 1, allowing the airbag cushion 18 to be formed by splicing and bonding capsule pieces 3 with the same structure. This effectively reduces the types of raw materials, facilitates raw material processing, and lowers raw material costs. In addition, since the capsule 3 is long and narrow, two capsule 3 can be stacked and bonded vertically to form an airbag with multiple capsule strips. Compared with the method of forming capsule strips and airbag by bonding sheets in sequence, it has the advantages of convenient processing and good sealing performance.

[0029] In this embodiment, one side edge of the capsule 3 is provided with equally spaced connecting pieces 7 (e.g., ...). Figure 3 As shown, the airbag 3 is bonded and fixed to adjacent airbags 3 side by side via connecting pieces 7. The peripheries of the upper piece 1 and the lower piece 2 form connecting areas surrounding the airbag groove 4, buffer groove 5, and ventilation groove 6. The upper piece 1 and the lower piece 2 are vertically stacked and bonded together through their corresponding connecting areas. During the overall welding and bonding process, adjacent airbags 3 located on the same horizontal plane and used to form the upper piece 1 or the lower piece 2 are stacked and bonded together via corresponding connecting pieces 7. Vertically stacked airbags 3 are bonded together via their corresponding connecting areas, so that the airbags 3 are joined and bonded together to form the airbag cushion 18.

[0030] In this embodiment, the capsule 3 includes capsule grooves 4 evenly spaced along its length and buffer grooves 5 disposed at its ends. Ventilation grooves 6 are connected between adjacent capsule grooves 4 and between buffer grooves 5 and adjacent capsule grooves 4. After the bonding process is completed, the capsule grooves 4, buffer grooves 5, and ventilation grooves 6 are respectively joined to form a capsule cavity 8, a buffer cavity 9, and a ventilation tube 10 (e.g., ...). Figure 5 As shown), the ventilation tube 10 is arranged along the length of the capsule 3 and connects the capsule cavity 8 and the buffer cavity 9 along the way (as shown). Figure 6 (As shown). A through hole 12 is provided on the top or bottom wall of the buffer cavity 9 for inserting and connecting an air nozzle 11. The inner end of the air nozzle 11 is inserted into the through hole 12 and communicates with the buffer cavity 9, while the outer end protrudes from the side edge of the airbag pad 18 and communicates with an external air source. In use, the air nozzle 11 is connected to an external air source through an air tube, allowing the airbag cavity 8, the air tube 10, and the buffer cavity 9 to all be connected to an external air source via the air nozzle 11. This ensures that the air pressure inside the airbag cavity 8 is adjustable and the firmness can be adjusted, providing comfortable support for the user.

[0031] In this embodiment, the bladder groove 4 is cylindrical, and the groove wall of the bladder groove 4 is formed into a wave shape that can expand and contract along its axis by radial reciprocating bending. This not only facilitates demolding during injection molding, ensuring the integrity of the bladder piece 3 and preventing crushing damage, but also utilizes the wave-shaped bladder groove 4 to obtain a larger vertical expansion and contraction range, thereby increasing the range of softness and hardness adjustment to meet the diverse usage needs of users. In addition, the bladder groove 4 can also be a frustum shape with a top diameter slightly smaller than the bottom diameter, which can further improve the convenience of injection molding demolding and ensure that the bladder cavity has a good support effect, and should also be considered as a specific implementation of this embodiment.

[0032] In this embodiment, the buffer cavity 9 is arranged linearly along one side of the airbag pad 18, so that the air nozzle 11 is also located on the same side of the airbag pad 18. This facilitates the use of air tubes to connect each air nozzle 11 in series, thereby ensuring that the air chamber 8 connected to each air nozzle 11 can adjust the air pressure at the same time, and ensuring that the softness and hardness of each area of ​​the airbag pad 18 remain balanced.

[0033] In this embodiment, the inner end of the air nozzle 11 extends to form a sealing sheet 13 that can fit against the periphery of the through hole 12 (e.g., Figure 4 (As shown). The sealing sheet 13 can fit against the periphery of the through hole 12. By setting the sealing sheet 13, the contact area between the air nozzle 11 and the wall of the buffer cavity 9 is increased, thereby improving the sealing performance.

[0034] Example 2:

[0035] Compared to Embodiment 1, this embodiment provides a mattress.

[0036] like Figure 7 The mattress shown includes a mattress body comprising an airbag pad 18, a support layer 14 fitted onto the airbag pad 18, a perimeter 15 surrounding the support layer 14, and a comfort layer 16 stacked on top of the airbag pad 18. The airbag pad 18 is formed by splicing and bonding together airbag pieces 3 with the same structure, effectively reducing production difficulty, thereby improving mattress production efficiency and reducing processing costs.

[0037] In this embodiment, the support layer 14 has through slots 17 for vertically embedding the airbag cushion 18. The support layer 14 consists of two vertically clamping airbag cushions 18, with the top and bottom of the airbag cavity 8 inserted into the corresponding through slots 17, which serves to horizontally limit the airbag cavity 8 and ensure that the airbag cavity 8 can vertically expand and contract along its axis during inflation and deflation. This provides comfortable support for the user and prevents the end of the airbag cavity 8 from tipping over.

[0038] The other structures and effects of the airbag cushion 18 described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
