Description

Technical Field

[0001] The utility model belongs to the technical field of furniture and relates to an airbag cushion and a mattress with high production efficiency. Background Art

[0002] An existing airbag cushion includes a base layer and a unit bladder fixed on the base layer. The unit bladder includes a laminate and a massage body. Each laminate includes multiple unit layers. The outer diameters of each unit layer are smaller at the upper and lower ends and larger in the middle. In the process of fixing the unit layers to the base layer, the bottom unit layer must first be welded to the base layer from the inside, and then the next unit layer must be welded to the bottom unit layer from the inside. The unit layers are stacked and welded in sequence. It is impossible to first make multiple unit layers into a laminate and then fix the laminate to the base layer, resulting in low production efficiency. Summary of the Invention

[0003] The utility model aims to solve the problems existing in the prior art and proposes an airbag cushion and a mattress with high production efficiency, so as to overcome the defect of low production efficiency of the prior airbag cushion.

[0004] The utility model is achieved in this way:

[0005] An airbag cushion with high production efficiency comprises a first base layer and a plurality of unit cells. The unit cells comprise a laminate and a half-layer connecting piece connected to the lower end of the laminate. The outer edge of the half-layer connecting piece is heat-melted to the first base layer.

[0006] The laminate and the first base layer are connected by providing a half-layer connecting sheet. Instead of stacking and welding the unit layers one by one from the inside up to the top layer as in the prior art, the laminate, half-layer connecting sheet, and other components are prefabricated into a unit capsule. The lower edge of the half-layer connecting sheet is designed to be sufficiently large to ensure that the downward projection of the laminate falls completely within the lower edge of the half-layer connecting sheet. This allows the lower edge of the half-layer connecting sheet to be hot-melt-connected to the first base layer from the outside of the unit capsule. This method changes the original complex and time-consuming sequence of welding and fixing the unit layers one by one. Using this new connection structure, the unit capsule can be prefabricated into a semi-finished product and then fixed to the first base layer, simplifying the overall production process and improving production efficiency.

[0007] Preferably, the unit airbag includes a massage body connected to the upper end of the laminate. The downward projection of the massage body is smaller than that of the laminate, and the downward projection of the laminate falls within the outer edge of the half-layer connecting sheet. The massage body, which contacts the user and performs the massage function, only occupies a relatively small space above the laminate. This ensures that massage stimulation points are covered without affecting the structural stability, gas storage, and cushioning functions of the underlying laminate, which serves as the airbag body. Together, they form a more efficient airbag cushion structure.

[0008] Preferably, the laminated body includes a plurality of unit layers, and the height of the massage body is greater than the unit layers. The laminated body is composed of a plurality of unit layers, which makes it easy for the airbag cushion to achieve different air pressure support and cushioning performance. Each unit layer can work together after inflation, adjusting the overall softness and hardness according to the force conditions to adapt to the pressure requirements of different body parts. The height of the massage body is greater than the unit layer. On the one hand, it is to highlight the massage function, making it easier to contact the human body surface and produce a significant pressing effect. When the user lies on the airbag cushion, the higher massage body can be given priority to receive force, triggering its internal massage mechanism; on the other hand, this height difference design ensures that the massage body will not be overly restricted by the deformation of the unit layer when performing its function. The two cooperate with each other in space to meet the user's dual requirements for a comfortable massage experience and a stable support function.

[0009] Preferably, the half-layer connecting sheet and the laminate have a connecting hole that connects to the massage body. This ensures that the massage body also receives stable air pressure support, keeping it structurally full and ready to provide effective massage feedback to the user at any time. Furthermore, this connecting design forms an organic air pressure linkage system within the entire airbag cushion. The laminate serves as the primary load-bearing and cushioning structure, and its air pressure changes are transmitted to the massage body in real time through the connecting hole. The massage body adjusts its shape and pressing force according to air pressure fluctuations, closely cooperating with the support function of the laminate to further optimize the massage experience.

[0010] Preferably, the airbag cushion includes a second base layer, an air passage is provided between the second base layer and the first base layer, communicating with the communication hole, and the second base layer is provided with an inflation nozzle. When the airbag cushion needs to be inflated, an external air source injects gas through the inflation nozzle on the second base layer, and the gas then flows along the air passage. Because the air passage is connected to the communication holes between the first half-layer connecting sheet, the laminated body, and the massage body, the gas can be accurately and efficiently distributed to key locations throughout the interior of the airbag cushion.

[0011] Preferably, multiple unit bladders are fixed to the same first base layer, and the unit bladders on the same first base layer are inflated through the same inflation nozzle. The second base layer and the inflation nozzle provide a centralized air intake port, making operation more convenient and efficient. The user only needs to connect the air source to the inflation nozzle to complete the inflation process of multiple unit bladders at once, without having to inflate each unit bladder separately, greatly saving inflation time and energy.

[0012] Preferably, multiple rows of the first base layer are provided on the second base layer. These multiple rows of the first base layer provide targeted support for different parts of the body, avoiding the problems of excessive local pressure or insufficient support caused by the single-plane support of traditional airbag cushions. For example, when a user rests on the airbag cushion after a long period of desk work, different rows of the first base layer corresponding to the shoulders and waist can adjust the air pressure and deformation degree respectively, conforming to the body's curves to provide precise cushioning and effectively relieve fatigue in specific areas.

[0013] Preferably, the periphery of the second base layer and the first base layer is bonded by non-complete hot melt bonding, so as to form an air passage between the second base layer and the first base layer, and the peripheries of the two base layers are sealed and connected.

[0014] Preferably, the first base layer and the second base layer are provided with corresponding positioning holes, the positioning holes are staggered with the unit capsules, and the first base layer and the second base layer are welded at the positioning holes. The presence of the positioning holes greatly simplifies and refines the assembly process of the first base layer and the second base layer. Workers only need to place the two layers of base layers in correspondence with the positioning holes to quickly achieve precise alignment without the need for complicated measurement and debugging, which significantly improves production efficiency. Especially in large-scale industrial production, it can effectively reduce assembly time and defective rate, and reduce production costs. The connection points formed by welding at the positioning holes greatly enhance the connection strength between the first base layer and the second base layer. In daily use, in the face of various external force impacts caused by frequent handling, squeezing and changes in user posture, the two layers of base layers are effectively prevented from separating and dislocating, ensuring the stable operation of internal components and extending the service life of the product. Staggered unit capsule welding avoids direct damage to the unit capsule caused by welding heat.

[0015] Preferably, the first and second base layers have multiple ventilation holes, staggered between the unit cells. The first and second base layers are welded at the ventilation holes. The diameter of the ventilation holes is larger than the positioning holes, and the positioning holes are more numerous than the ventilation holes. The ventilation holes improve the airbag cushion's breathability. A large number of positioning holes provides operators with a clear alignment reference, making the assembly process more precise and efficient, shortening assembly time, significantly improving production efficiency, and providing strong support for large-scale mass production.

[0016] A mattress comprises the above-mentioned airbag cushion.

[0017] The utility model provides an airbag cushion and mattress with high production efficiency. The unit airbags can be prefabricated into semi-finished products by using a new connecting structure and a half-layer connecting piece, and then fixed to the first base layer. The overall structure simplifies the production process and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] This embodiment provides a mattress, which is a specific application of the innovative solution of the utility model on the mattress. The mattress includes an airbag cushion, such as Figure 1-6 As shown, the airbag cushion includes a first base layer 100 and a plurality of unit cells 300 . The unit cells 300 include a laminate 310 and a half-layer connecting sheet 320 connected to the lower end of the laminate 310 . The outer edge of the half-layer connecting sheet 320 is heat-melted to the first base layer 100 .

[0028] By providing a half-layer connecting piece 320 to connect the laminate 310 and the first base layer 100, since the outer edge of the half-layer connecting piece 320 can be conveniently connected to the first base layer 100 from the outside by heat-melting, it is no longer necessary to stack and weld the unit layers 311 layer by layer from the inside to the top layer as in the prior art. Instead, the laminate 310, the half-layer connecting piece 320 and other components are pre-made into a unit capsule 300, such as Figure 7As shown, the unit capsule 300 can be prefabricated into a semi-finished product by using the new connecting structure half-layer connecting sheet 320 and then fixed to the first base layer 100, which simplifies the production process from the overall structure and improves production efficiency.

[0029] like Figure 4 、 6 As shown, the unit airbag 300 includes a massage body 330 connected to the upper end of the laminate 310. The downward projection of the massage body 330 is smaller than that of the laminate 310, and the downward projection of the laminate 310 falls within the outer edge of the half-layer connecting sheet 320. The massage body 330, which contacts the user and performs the massage function, only occupies a relatively small space above the laminate 310. This ensures that massage stimulation points are covered without affecting the structural stability, gas storage, and cushioning functions of the underlying laminate 310, which serves as the airbag main body. Together, they form a more efficient airbag cushion structure. The outer edge of the half-layer connecting sheet 320, which is the lower edge of the half-layer connecting sheet 320 in this embodiment and contacts the base layer, is designed to be sufficiently large to ensure that the downward projection of the laminate 310 falls completely within the outer edge of the half-layer connecting sheet 320, further facilitating the heat-seal connection of the unit airbag 300 to the first base layer 100 from the outside.

[0030] During the manufacturing process of the airbag cushion, the massage body 330, the laminated body 310 and the half-layer connecting sheet 320 can be made into a unit bag 300, and then the unit bag 300 is fixed to the first base layer 100 as a whole, that is, by hot-melt-connecting the lower edge of the half-layer connecting sheet 320 to the first base layer 100.

[0031] like Figure 4 As shown, the laminate 310 comprises multiple unit layers 311. This embodiment uses four unit layers 311 as an example. In other alternative embodiments, the number of unit layers 311 can also be two, three, or more than four. The massage body 330 is taller than the unit layers 311. The laminate 310, composed of multiple unit layers 311, enables the airbag cushion to achieve varying air pressure support and cushioning properties. Each unit layer 311 works collaboratively after inflation, adjusting the overall softness and hardness based on the force applied, to meet the pressure requirements of different body parts. The massage body 330 is taller than the unit layers 311. This is done to enhance the massage function, making it easier to contact the human body surface and produce a significant pressure effect. When a user lies on the airbag cushion, the taller massage body 330 receives force first, triggering its internal massage mechanism. Furthermore, this height difference ensures that the massage body 330 is not excessively restricted by the deformation of the unit layers 311 during its function. These two spatially coordinated features meet the user's dual requirements for a comfortable massage experience and stable support. In other optional embodiments, the height of the massage body 330 may also be equal to or less than the height of the unit layer 311 .

[0032] like Figure 4 As shown, the half-layer connecting sheet 320 and the laminate 310 have a connecting hole 340 that connects to the massage body 330. This ensures that the massage body 330 also receives stable air pressure support, keeping it structurally full and ready to provide effective massage feedback to the user at all times. Furthermore, this interconnected design forms an organic air pressure linkage system within the entire airbag cushion. The laminate 310 serves as the primary load-bearing and cushioning structure, and its air pressure changes are transmitted to the massage body 330 in real time through the connecting hole 340. The massage body 330 adjusts its shape and pressing force based on air pressure fluctuations, closely cooperating with the support function of the laminate 310 to further optimize the massage experience.

[0033] like Figure 4 As shown, the airbag cushion includes a second base layer 200. An air channel 130 is defined between the second base layer 200 and the first base layer 100, connecting to the communication hole 340. An inflation nozzle 210 is provided on the second base layer 200. To inflate the airbag cushion, an external air source injects gas through the inflation nozzle 210 on the second base layer 200. The gas then flows along the air channel 130. Because the air channel 130 connects to the communication hole 340 between the semi-layer connecting sheet 320, the laminate 310, and the massage body 330, the gas can be accurately and efficiently distributed to key locations throughout the interior of the airbag cushion.

[0034] like Figure 1-6 As shown, multiple unit bladders 300 are secured to the same first base layer 100, and the unit bladders 300 on the same first base layer 100 are inflated via the same inflation nozzle 210. The second base layer 200, in conjunction with the inflation nozzle 210, provides a centralized air intake port, making operation more convenient and efficient. The user simply connects the air source to the inflation nozzle 210 to inflate multiple unit bladders 300 simultaneously, eliminating the need to inflate each unit bladder 300 individually, significantly saving time and effort. In other optional embodiments, a separate first base layer 100 and inflation nozzle 210 may be provided for each unit bladder 300.

[0035] like Figure 1 、 2 As shown, multiple rows of first base layers 100 are provided on the second base layer 200. Figure 1Taking 13 rows as an example, multiple rows of first base layers 100 provide targeted support for different parts of the body, avoiding the problems of excessive local pressure or insufficient support caused by the single-plane support of traditional airbag cushions. For example, when a user rests on the airbag cushion after a long period of desk work, different rows of first base layers 100 corresponding to the shoulders and waist can adjust the air pressure and deformation degree respectively, conforming to the body's curves to provide precise cushioning and effectively relieve fatigue in specific areas. In other optional embodiments, all unit bladders 300 can also share a single first base layer 100 and inflation nozzle 210.

[0036] Furthermore, the periphery of the second base layer 200 and the first base layer 100 is partially hot-melt bonded, so that an air channel 130 is formed between the second base layer 200 and the first base layer 100, and the peripheries of the two are sealed and connected.

[0037] like Figure 1 、 2 As shown, the first and second base layers 100, 200 are provided with corresponding positioning holes 110, which are offset from the unit capsules 300. The first and second base layers 100, 200 are welded at the positioning holes 110. The presence of the positioning holes 110 greatly simplifies and streamlines the assembly process of the first and second base layers 100, 200. Workers simply place the two base layers in alignment with the positioning holes 110 to quickly and precisely align them, eliminating the need for complex measurement and adjustment. This significantly improves production efficiency, and in large-scale industrial production, effectively reduces assembly time and defective product rates, thereby lowering production costs. Welding at the positioning holes 110 significantly strengthens the connection between the first and second base layers 100, 200. In daily use, the two base layers are effectively prevented from separating and misaligning due to frequent handling, squeezing, and changes in user posture, ensuring stable operation of internal components and extending the product's lifespan. Staggering the unit capsules 300 for welding avoids direct damage to the unit capsules 300 from welding heat.

[0038] Furthermore, the first and second base layers 100 and 200 are provided with multiple ventilation holes 120, which are staggered relative to the unit cells 300. The first and second base layers 100 and 200 are welded together at the ventilation holes 120. The diameter of the ventilation holes 120 is larger than the positioning holes 110, and the positioning holes 110 are more numerous than the ventilation holes 120. The ventilation holes 120 enhance the airbag cushion's breathability. The numerous positioning holes 110 provide operators with a clear alignment reference, making the assembly process more precise and efficient, shortening assembly time and significantly improving production efficiency, thus providing strong support for large-scale mass production.

[0039] The second base layer 200 is not completely hot-melt bonded to the first base layer 100. Figure 2 As shown, the second base layer 200 and the first base layer 100 form a local hot melt bonding area 140 at their peripheries, the periphery of the positioning hole 110 and the periphery of the vent hole 120, and the remaining positions of the two can be spaced to form air channels 130.
