Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly relates to an airbag pad and a mattress using the same. Background Art

[0002] The existing mattress includes an airbag pad. The airbag pad includes airbag strips arranged closely in the front-back direction. The airbag strips are provided with capsule component assemblies arranged in a straight line. The adjacent capsule component assemblies are connected through an air passage channel so that the air pressures of the capsule component assemblies on the airbag strips can be adjusted synchronously, and further, when the adjacent airbag strips are communicated with each other, the air pressure can be adjusted synchronously. The existing air passage channel is formed by connecting the pipe orifices extending outwards from the capsule component assemblies. When connecting, the end faces of the corresponding pipe orifices are aligned and abutted to form an annular welding area. Since the wall thickness of the pipe orifices is small, the welding area is narrow, which not only increases the difficulty of welding and affects the production efficiency, but also affects the sealing reliability due to the easy force damage of the welding area, and further shortens the service life of the airbag strip and affects the use experience. Content of the Utility Model

[0003] In order to solve the deficiencies of the existing technology, the utility model provides an airbag pad and a mattress using the same. An upper sheet and a lower sheet are respectively arranged on the upper cover part and the lower cover part of the capsule component assembly. The adjacent capsule component assemblies form an air passage channel through the overlapping welding of the corresponding upper sheet and lower sheet, effectively increasing the welding area, not only improving the sealing reliability, but also facilitating the welding operation and enhancing the use experience.

[0004] The utility model is realized in the following way: An airbag pad includes airbag strips arranged closely in the front-back direction. The airbag strips include capsule component assemblies arranged linearly. The capsule component assemblies include an upper cover part with an upper sheet and a lower cover part with a lower sheet. The capsule component assemblies are assembled by overlapping the upper cover part and the lower cover part. The upper sheet and the lower sheet located between adjacent capsule component assemblies are adhesively overlapped to form an air passage channel for communicating adjacent capsule component assemblies. An upper sheet and a lower sheet are respectively arranged on the upper cover part and the lower cover part of the capsule component assembly. The adjacent capsule component assemblies form a cross-connected air passage channel through the overlapping welding of the corresponding upper sheet and lower sheet, effectively increasing the welding area, not only improving the sealing reliability to ensure the sealed connection of adjacent capsule component assemblies and prevent the occurrence of extrusion damage, but also facilitating the welding operation and enhancing the use experience.

[0005] Preferably, the two sides of the bottom surface of the upper cover part extend to form the upper sheet, and the two sides of the top surface of the lower cover part extend to form the lower sheet, so that the airbag component assemblies are connected in series through the corresponding air passage channels to form the airbag strips. The upper sheets are arranged on both sides of the upper cover part, and the lower sheets are arranged on both sides of the lower cover part, so that the adjacent capsule component assemblies can be adhesively overlapped through the two upper sheets of the corresponding upper part and the two lower sheets of the corresponding lower part, and further enclose to form an air passage channel capable of cross-connecting adjacent capsule component assemblies, and a mutually connected airbag strip is formed through the series connection of multiple capsule component assemblies.

[0006] Preferably, the upper sheets are symmetrically arranged on both sides of the bottom surface of the upper cover part, and the lower sheets are symmetrically arranged on both sides of the top surface of the lower cover part, so that the upper sheets and the lower sheets are aligned and stacked. The upper sheets are symmetrically arranged on both sides of the upper cover part, and the lower sheets are symmetrically arranged on both sides of the lower cover part, which not only ensures that the corresponding upper sheets and lower sheets can be aligned and stacked, effectively increases the area of the welding region, improves the sealing reliability, but also ensures that the bladder assembly can be arranged in a straight line, thereby forming a linear airbag strip.

[0007] Preferably, the upper sheets and the lower sheets are stacked and welded to form an air passage channel isolated from the outside, and the two ports of the air passage channel are respectively communicated with the inner cavities of the corresponding bladder assemblies. The middle parts of the upper sheets and the lower sheets enclose to form the air passage channel, and the side parts of the upper sheets and the lower sheets are aligned and stacked to form a welding region, ensuring that the air passage channel is hermetically isolated from the outside space.

[0008] Preferably, the middle part of the upper sheet bulges upward to form an upper groove, and the middle part of the lower sheet sinks downward to form a lower groove. The upper groove and the lower groove are vertically stacked and enclose to form the air passage channel. By providing the upper groove and the lower groove, it is ensured that the cross-sectional area of the air passage channel meets the air flow rate requirements, and the air passage channel is prevented from being deformed due to indentation, which affects the air flow smoothness.

[0009] Preferably, the upper grooves are symmetrically arranged along the radial direction of the upper cover part, and the lower grooves are symmetrically arranged along the radial direction of the lower cover part, so that the bladder assemblies are arranged in a straight line, ensuring that the airbag strip can be in a long strip shape and facilitating the splicing to form an airbag pad.

[0010] Preferably, a lower avoidance groove is provided at the extended end of the lower sheet, adjacent lower sheets are stacked on each other and embedded in the corresponding lower avoidance grooves, an upper avoidance groove is provided at the extended end of the upper sheet, and adjacent upper sheets are stacked on each other and embedded in the corresponding upper avoidance grooves, so that each section of the air passage channel has the same wall thickness. The lower avoidance grooves are arranged on the opposite surfaces of the corresponding lower sheets, so that the ends of the two lower sheets can be embedded in the corresponding lower avoidance grooves respectively, which not only ensures that there is a large welding region between the two lower sheets, but also effectively reduces the thickness after the lower sheets are stacked, plays a role of resisting and positioning the adjacent bladder assemblies, and ensures that the distance between adjacent bladder assemblies is the same. Similarly, the upper avoidance grooves are arranged on the corresponding surfaces of the upper sheets, playing a role of resisting and positioning.

[0011] Preferably, connection edges are provided at the front edge and the rear edge of the bladder assembly, and the front edge and the rear edge of adjacent airbag strips are stacked, welded and adhered through the corresponding connection edges. Adjacent airbag strips are stacked, welded and adhered through the corresponding connection edges, so that the airbag strips can be spliced to form an airbag pad.

[0012] Preferably, the front edge of the top surface of the upper cover part and the rear edge of the bottom surface of the lower cover part form the connecting edge by extension, or the rear edge of the top surface of the upper cover part and the front edge of the bottom surface of the lower cover part form the connecting edge by extension. The corresponding connecting edges of adjacent capsule components are respectively arranged on the upper cover part and the lower cover part, which not only ensures the vertical dislocation of the corresponding connecting edges, ensures the connection reliability, but also effectively reduces the number of layers of the overlapping connecting edges and facilitates the assembly operation.

[0013] 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 hardness by inflating and deflating at a preset position, thereby improving the use comfort of the pad body.

[0014] The beneficial effects of the present utility model: An upper sheet and a lower sheet are respectively arranged on the upper cover part and the lower cover part of the capsule component. The corresponding upper sheet and lower sheet of adjacent capsule components are overlapped and welded to form a cross-connected air passage, effectively increasing the welding area, which not only improves the sealing reliability, ensures the sealed connection of adjacent capsule components, prevents the occurrence of extrusion and breakage, but also facilitates the welding operation and improves the use experience.

[0023] The following further illustrates the substantial features of the present utility model in conjunction with the accompanying drawings of the specification and specific embodiments.

[0024] Embodiment 1:

[0025] This embodiment provides an airbag cushion.

[0026] As Figure 1 and 2 shown, an airbag cushion includes airbag strips 1 arranged closely in the front - to - back direction. The airbag strips 1 include linearly arranged bladder components. The bladder components include an upper cover part 3 with an upper placement piece 2 and a lower cover part 5 with a lower placement piece 4. The bladder components are assembled by overlapping the upper cover part 3 and the lower cover part 5. The upper placement piece 2 and the lower placement piece 4 between adjacent bladder components are adhesively overlapped to form an air passage channel 6 for connecting adjacent bladder components. By respectively arranging the upper placement piece 2 and the lower placement piece 4 on the upper cover part 3 and the lower cover part 5 of the bladder component, and forming a bridged air passage channel 6 by overlapping and welding the corresponding upper placement piece 2 and lower placement piece 4 between adjacent bladder components, the welding area is effectively increased, which not only improves the sealing reliability, ensures the sealed connection of adjacent bladder components, prevents the occurrence of extrusion and breakage, but also facilitates the welding operation and improves the user experience.

[0027] In this embodiment, both sides of the bottom surface of the upper cover part 3 are extended to form the upper placement piece 2, and both sides of the top surface of the lower cover part 5 are extended to form the lower placement piece 4 (as Figure 3 shown), so that the airbag components are connected in series through the corresponding air passage channels 6 to form the airbag strips 1. During installation, first, the upper cover part 3 and the lower cover part 5 of adjacent airbag components are overlapped, so that two upper placement pieces 2 and two lower placement pieces 4 on the corresponding sides are vertically overlapped and enclose to form an air passage channel 6; then, the welding area formed by the overlapping of the upper cover part 3 and the lower cover part 5 is welded and sealed, and the welding areas formed by the overlapping of the two upper placement pieces 2, the two lower placement pieces 4, and the overlapping of the adjacent upper placement piece 2 and lower placement piece 4 are welded and sealed.

[0028] Through the above operations, not only can an inner cavity isolated from the external space be enclosed between the upper cover part 3 and the lower cover part 5, but also an air passage channel 6 isolated from the external space can be formed between adjacent inner cavities, ensuring that adjacent inner cavities can be connected through the air passage channel 6. The periphery of the air passage channel 6 is sealed and wrapped by the welding area, and the width of the welding area is not less than 5 mm, ensuring the sealing reliability of the welding area and preventing the welding area from being damaged and leaking due to extrusion.

[0029] In this embodiment, the upper sheets 2 are symmetrically arranged on both sides of the bottom surface of the upper cover portion 3, and the midlines of the upper sheets 2 coincide with each other and pass through the axis of the upper cover portion 3. The upper grooves 7 are symmetrically arranged along the midline of the upper cover portion 3. The lower sheets 4 are symmetrically arranged on both sides of the top surface of the lower cover portion 5, and the midlines of the lower sheets 4 coincide with each other and pass through the axis of the lower cover portion 5. The lower grooves 8 are symmetrically arranged along the midline of the lower cover portion 5, which not only ensures that the upper cover portion 3 and the lower cover portion 5 can ensure the alignment and stacking of the upper sheets 2 and the lower sheets 4 when vertically stacked, but also ensures that the corresponding upper sheets 2 and lower sheets 4 of adjacent bladder components can be aligned and stacked and arranged in a straight line, so as to form a linear bladder strip 1, which is convenient for the bladder strip 1 to be assembled into a bladder pad 12.

[0030] In this embodiment, the upper sheets 2 and the lower sheets 4 are stacked and welded to form an air passage 6 isolated from the outside, and the two ports of the air passage 6 are respectively communicated with the inner cavities of the corresponding bladder components. Specifically, the middle part of the upper sheet 2 bulges upward to form the upper groove 7, and the middle part of the lower sheet 4 depresses downward to form the lower groove 8. The upper groove 7 and the lower groove 8 are vertically stacked and enclose to form the air passage 6. The upper groove 7 and the lower groove 8 are both penetrated along the midlines of the upper sheet 2 and the lower sheet 4, so that the air passage 6 formed by the stacking of the upper groove 7 and the lower groove 8 can be bridged between the inner cavities of the corresponding bladder components. The upper groove 7 is opened in the middle of the upper sheet 2, and the lower groove 8 is opened in the middle of the lower sheet 8, ensuring that the corresponding side parts of the upper sheet 2 and the lower sheet 4 can be stacked to form a welding area meeting the width requirements, and ensuring the sealing performance of the air passage 6.

[0031] In this embodiment, connection edges 11 are provided at both the front edge and the rear edge of the bladder component (as Figure 4 shown), and the front edges and the rear edges of adjacent bladder strips 1 are stacked, welded and adhered through the corresponding connection edges 11. During installation, adjacent bladder strips 1 are arranged side by side in the front-rear direction and are welded and fixed through the stacked connection edges 11, so that the relative positions between adjacent bladder strips 1 are fixed and assembled to form the bladder pad 12.

[0032] In this embodiment, only one connection edge 11 needs to be provided on both the front edge and the rear edge of adjacent bladder strips 1, which not only ensures that adjacent bladder strips 1 can be stacked and fixedly connected through the corresponding connection edges 11, but also effectively limits the stacking quantity of the connection edges 11, thereby facilitating the welding operation. For this reason, the front edge of the top surface of the upper cover portion 3 and the rear edge of the bottom surface of the lower cover portion 5 are extended to form the connection edge 11; or, the rear edge of the top surface of the upper cover portion 3 and the front edge of the bottom surface of the lower cover portion 5 are extended to form the connection edge 11, which can not only ensure that adjacent bladder strips 1 are stacked, adhered and fixedly connected through the corresponding connection edges 11, but also simplify the welding operation by limiting the quantity of the connection edges 11, improve the assembly efficiency, and stack and adhere the connection edges 11 provided vertically offset on adjacent bladder components to ensure that adjacent bladder components are arranged at the same height and ensure the flatness of the top surface of the bladder pad 12.

[0033] Example Two:

[0034] Compared with Example One, this example provides another airbag pad.

[0035] As shown in Figure 5 and 6 , a lower avoidance groove 9 is provided at the extension end of the lower placement piece 4. Adjacent lower placement pieces 4 are stacked on top of each other and embedded in the corresponding lower avoidance groove 9. An upper avoidance groove 10 is provided at the extension end of the upper placement piece 2. Adjacent upper placement pieces 2 are stacked on top of each other and embedded in the corresponding upper avoidance groove 10, so that each section of the air passage 6 has the same wall thickness. By providing the upper avoidance groove 10 and the lower avoidance groove 9, not only can the thickness when the corresponding upper placement pieces 2 and the corresponding lower placement pieces 4 adhere to each other be reduced, preventing the welding sealability from being affected due to the uneven stacking surface between the upper placement piece 2 and the lower placement piece 4, but also the relative positions between adjacent airbag components can be ensured to be fixed through clamping and positioning, improving the assembly efficiency of the airbag strip 1 and effectively reducing the situation of defective products caused by the distance deviation between adjacent airbag components.

[0036] In this example, lower avoidance grooves 9 are provided on the corresponding surfaces of the ends of the corresponding lower placement pieces 4 of adjacent airbag components. The ends of the lower placement pieces 4 are embedded in the corresponding lower avoidance grooves 9, so that the lower placement pieces 4 are stacked and obtain a flat top surface. Upper avoidance grooves 10 are provided on the corresponding surfaces of the ends of the corresponding upper placement pieces 2 of adjacent airbag components. The ends of the upper placement pieces 2 are embedded in the corresponding upper avoidance grooves 10, so that the upper placement pieces 2 are stacked and obtain a flat bottom surface. The flat bottom surface of the upper placement piece 2 and the flat top surface of the lower placement piece 4 are matched and welded to ensure that the air passage 6 has good sealing performance.

[0037] The other structures and effects of the airbag pad in this example are the same as those in Example One and will not be elaborated here.

[0038] Example Three:

[0039] Compared with Example One or Two, this example provides a mattress.

[0040] As shown in Figure 7 , the mattress includes a pad body, and the pad body includes an airbag pad 12 and a limit block 13 that clamps and wraps the airbag pad 12. The limit block 13 plays a role in clamping, positioning and protecting the airbag pad 12, ensuring that the airbag pad 12 is adjusted in hardness through inflation and deflation at a preset position, thereby improving the use comfort of the pad body.

[0041] In this embodiment, the limiting block 13 is provided with perforations, and the number and positions of the perforations are matched one by one with the bladder components on the airbag pad 12. During installation, the limiting block 13 wraps the airbag pad 12, and the perforations are sleeved on the corresponding bladder components, so that each bladder component is limited by the inner wall of the perforation, ensuring that the bladder components can achieve vertical expansion and contraction under the guidance of the perforations, and further adjusting the softness and hardness by adjusting the air pressure to provide comfortable support for the user.

[0042] The other structures and effects of the airbag pad in this embodiment are the same as those in Embodiment 1 or 2, and will not be elaborated here.
