Description
Technical Field
[0001] The utility model relates to the field of bedding, in particular to an airbag pad and a mattress using the same. Background Art
[0002] The existing airbag pad includes airbag strips arranged closely in the front-back direction. The airbag strips include unit airbags arranged in a linear shape. The unit airbags on the same airbag strip have the same top surface and bottom surface, so that the airbag pad has a flat top surface and bottom surface, thereby providing stable support for the user. The unit airbag includes vertically stacked air chambers. The air chambers can realize vertical telescopic deformation when inflated and deflated. The vertical telescopic deformations generated by each air chamber can be superimposed and accumulated, so that the unit airbag has a larger vertical deformation space. The air chamber has a structure with good resistance to horizontal deformation, so that the air chamber can only perform vertical telescopic deformation, and it is ensured that the top surface of the air chamber always maintains a horizontal posture. Since the user's surface is a curved surface, when the user lies down and contacts the top surface of the air chamber, the top surface of the air chamber cannot match and fit with the user's surface due to the horizontal setting. The top surface of the airbag pad adapts to the contour of the user's surface, resulting in the user being concentratedly stressed due to the reduction of the contact area between the surface and the top surface of the airbag pad, affecting the lying comfort. Content of the Utility Model
[0003] In order to solve the deficiencies of the prior art, the utility model provides an airbag pad and a mattress using the same. The middle parts of the bottom surface of the upper airbag body and the top surface of the lower airbag body are adhesively interconnected, effectively reducing the limitation on the horizontal inclination of the upper airbag body, so that the top surface of the unit airbag can freely turn and fit with the user's surface, improving the lying comfort.
[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 unit airbags arranged in a linear shape. The unit airbag includes an upper airbag body and a lower airbag body. The middle parts of the bottom surface of the upper airbag body and the top surface of the lower airbag body are adhesively interconnected by welding, so that the top surface of the upper airbag body can swing freely and fit with the supported object. The middle parts of the bottom surface of the upper airbag body and the top surface of the lower airbag body are adhesively connected by welding to form an annular welding area. By reducing the outer diameter of the welding area, the limitation on the lateral inclination action of the upper airbag body is reduced, so that the upper airbag body can tilt and swing with the middle part of its bottom surface as the center under the action of an external force, and then the axis of the upper airbag body tilts and expands and contracts along the axis direction, ensuring that the top surface orientation of the upper airbag body can be adjusted by swinging and fit with the user's surface. By increasing the contact area with the user's surface, the support reliability is improved, and thus the lying comfort is effectively improved. Also, a channel connecting the upper airbag body and the lower airbag body is arranged in the space in the middle of the welding area to ensure that the air pressures in the upper airbag body and the lower airbag body can be adjusted synchronously, thereby realizing the free adjustment of the softness and hardness of the unit airbag and improving the use experience.
[0005] Preferably, the outer edge portions of the bottom surfaces of the upper bladder and the lower bladder form matching annular limiting surfaces. When the upper bladder is tilted to a preset angle, it is restricted by the limiting surface to prevent the axis of the upper bladder from tilting excessively. This effectively prevents the situation where the axis of the upper bladder tilts excessively, ensuring that the upper bladder can automatically return to the original state with the axis vertical after the external force disappears. After the unit bladder is inflated, an included angle for the upper bladder to swing is formed between the outer edge portion of the upper cover plate and the outer edge portion of the lower cover plate, providing a swinging space for the upper bladder.
[0006] Preferably, an upper air port is provided in the middle of the bottom surface of the upper bladder, and a lower air port is provided in the middle of the top surface of the lower bladder. The peripheries of the upper air port and the lower air port are vertically stacked and welded and adhered to align and connect the upper air port and the lower air port. The peripheries of the upper air port and the lower air port are mutually attached and welded and fixed to form an annular welding area, ensuring that a channel for the upper air port and the lower air port to communicate is formed within the welding area. The upper air port, the lower air port, and the axis of the unit bladder are arranged on the same line, ensuring that the annular welding area is coaxial with the unit bladder. This not only facilitates the upper bladder to tilt in any radial direction but also provides support for the upper bladder, ensuring that the upper bladder can provide an outward support force along its axis when swinging to any angle, and also ensuring that the upper bladder can return to the original state with the axis vertical when the external force is withdrawn.
[0007] Preferably, the welding area formed by the stacked peripheries of the upper air port and the lower air port is annular, and the width of the welding area is A, where A≥5mm. This not only improves the sealing reliability by increasing the width of the welding area but also reduces the outer diameter of its outer edge by restricting the width of the welding area, thereby improving the tilting and swinging sensitivity of the upper bladder.
[0008] Preferably, the ratio of the outer diameter of the outer edge of the welding area to the outer diameter of the unit bladder is B, where B≤0.5. By restricting the parameter B, the outer diameter of the outer edge of the welding area is reduced, improving the swinging sensitivity of the upper bladder and ensuring that the top surface of the unit bladder can be matched and adhered to the user's surface through swinging.
[0009] Preferably, the upper bladder includes an upper cover part and an upper cover plate. An upper bladder cavity is provided in the upper cover part and is open downward, and the upper cover plate covers the bottom surface of the upper cover part and seals the upper bladder cavity. Both the upper cover part and the lower cover plate are integral independent components, which is not only convenient for batch processing but also can form the upper bladder through welding and adhesion, improving production efficiency. The upper cover part and the upper cover plate are adhesively fixed to form an upper bladder cavity with an upper air port. By reducing the diameter of the upper air port, the outer diameter of the outer edge of the welding area is reduced, thereby improving the swinging sensitivity of the upper bladder.
[0010] Preferably, the upper air port is opened in the middle of the upper cover plate. The upper cover plate not only plays a role in sealing the upper bladder cavity but also facilitates the adjustment of the air pressure in the upper bladder cavity through the opened upper air port.
[0011] Preferably, the periphery of the upper cover piece and the periphery of the bottom surface of the upper cover part are sealed by welding, and the periphery of the upper cover piece and the periphery of the bottom surface of the upper cover part are overlapped and welded to form an annular welding area between the outer edge of the upper cover piece and the periphery of the bottom surface of the upper cover part, ensuring that the upper cover piece and the upper cover part are sealed and fixed.
[0012] Preferably, the upper cover is formed by integral injection molding, which can not only utilize the opening on the bottom surface of the upper cover to achieve demolding, convenient for batch processing, but also ensure that the wall surface of the upper cover has good sealing, and ensure that the upper cover has an axial expansion and contraction range when inflated and deflated, thereby facilitating the provision of differentiated support strength for users and improving lying comfort.
[0013] Preferably, the airbag strip comprises an elongated lower bottom sheet and a lower cover sheet, the edges of which are overlapped and welded together, interconnecting the lower airbags to form a single unit. The overlapped lower bottom sheet and lower cover sheet weld together, interconnecting the lower airbags on the same airbag strip to form a single unit. This not only facilitates the secure connection of the upper airbags to the corresponding lower airbags, but also ensures that the lower airbags are interconnected, facilitating adjustment of the air pressure within each upper airbag. Furthermore, the distance between adjacent airbags meets the upper airbag swing requirements, preventing interference between adjacent upper airbags due to different axis inclination angles, and ensuring that each upper airbag can swing freely and adjustably.
[0014] Preferably, the lower bottom plate includes a unit bottom area arranged in a straight line and an air path bottom area connected between adjacent unit bottom areas, and the lower cover plate includes a unit cover area arranged in a straight line and an air path cover area connected between adjacent unit cover areas. The corresponding unit bottom areas and unit cover areas are overlapped and enclosed to form the lower capsule, and the corresponding air path bottom areas and air path cover areas are overlapped and enclosed to form an air path channel spanning between adjacent lower capsules. The unit bottom areas and unit cover areas are overlapped and welded to the periphery to form a lower capsule for supporting and positioning the upper capsule, and the air path bottom areas and air path cover areas are overlapped and welded to the edges to form an air path channel for connecting adjacent lower capsules, which not only ensures that the lower capsules are connected to each other and that the relative positions of the lower capsules are fixed, but also provides effective support for the upper capsules, ensuring that each upper capsule can swing freely.
[0015] Preferably, the lower air vent is opened in the middle of the unit cover area, which can be welded to the periphery of the lower air vent and the periphery of the upper air vent to ensure the sealed connection between the upper and lower bladders, and also ensure that the upper and lower bladders are aligned and fixed, making it convenient for the upper bladder to tilt in any direction.
[0016] Preferably, the periphery of the unit bottom area and the unit cover area are sealed by overlapping welding to form a lower bladder body, which not only improves the supporting reliability by increasing the outer edge diameter of the lower bladder body to prevent the upper bladder body from tilting as a whole due to excessive tilting, but also ensures the sealing of the lower bladder body to prevent air leakage.
[0017] Preferably, the side edges of the bottom air passage area and the air passage cover area are hermetically sealed by welding to form the air passage. The side edges of the bottom air passage area and the air passage cover area are welded to form the air passage, which not only ensures good airtightness along the air passage to prevent air leakage, but also ensures that both ends of the air passage communicate with the lower air chambers of the corresponding lower capsules, thereby ensuring that the air pressures in the unit capsules on the same airbag strip can be synchronously adjusted.
[0018] Preferably, connecting edges are provided on both the front edge and the rear edge of the lower bottom sheet. Adjacent airbag strips are stacked, welded, and adhered through the corresponding connecting edges. The adjacent airbag strips are closely arranged in the front-rear direction and are welded and fixed through the overlapping connecting edges, which not only ensures firm connection between adjacent airbag strips, but also ensures the relative positions of adjacent airbag strips are fixed, and they are sequentially joined to form the airbag pad.
[0019] 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 can be adjusted in hardness by inflating and deflating at a preset position, thereby improving the comfort of using the pad body.
[0020] The beneficial effects of the present utility model are as follows: The middle part of the bottom surface of the upper capsule and the middle part of the top surface of the lower capsule are adhesively welded to form an annular welding area. By reducing the outer diameter of the welding area, the restriction on the lateral tilting movement of the upper capsule is reduced, enabling the upper capsule to tilt and swing with its middle part of the bottom surface as the center under the action of an external force. Furthermore, the axis of the upper capsule is tilted and telescoped along the axis direction, ensuring that the orientation of the top surface of the upper capsule can be swing-adjusted to match and fit the user's surface, improving the load-bearing reliability by increasing the contact area with the user's surface, and effectively enhancing the lying comfort. Additionally, by providing a channel connecting the upper capsule and the lower capsule in the space in the middle of the welding area, it is ensured that the air pressures in the upper capsule and the lower capsule can be synchronously adjusted, thereby realizing free adjustment of the softness and hardness of the unit capsules and enhancing the use experience.

Detailed implementation mode
[0026] The following further describes the substantial features of the present utility model in conjunction with the accompanying drawings of the specification and the detailed implementation mode.
[0027] Embodiment 1:
[0028] This embodiment provides an airbag pad.
[0029] As Figure 1 and 2 shown, an airbag pad includes airbag strips 1 arranged closely in the front-back direction. The airbag strips 1 include unit bladders arranged in a linear pattern. The unit bladder includes an upper bladder 2 and a lower bladder 3. The middle parts of the bottom surface of the upper bladder 2 and the top surface of the lower bladder 3 are adhesively interconnected by welding, so that the top surface of the upper bladder 2 can swing freely and fit the supporting object. The middle parts of the bottom surface of the upper bladder 2 and the top surface of the lower bladder 3 are adhesively welded to form an annular welding area. By reducing the outer diameter of the welding area, the restriction on the lateral tilting movement of the upper bladder 2 is reduced, so that the upper bladder 2 can tilt and swing around the middle part of its bottom surface under the action of an external force. Furthermore, the orientation of the top surface of the upper bladder 2 can be adjusted to match the user's surface, improving the supporting reliability by increasing the contact area with the user's surface, thereby effectively improving the lying comfort. Also, a channel connecting the upper bladder 2 and the lower bladder 3 is provided in the space in the middle of the welding area to ensure that the air pressures in the upper bladder 2 and the lower bladder 3 can be adjusted synchronously, thereby realizing the free adjustment of the softness and hardness of the unit bladder and enhancing the use experience.
[0030] In this embodiment, an upper air port 4 is provided in the middle of the bottom surface of the upper bladder 2, and a lower air port 5 is provided in the middle of the top surface of the lower bladder 3. The peripheries of the upper air port 4 and the lower air port 5 are vertically stacked and welded together so that the upper air port 4 and the lower air port 5 are aligned and communicated. The area of the bottom surface of the upper bladder 2 located at the periphery of the upper air port 4 and the area of the top surface of the lower bladder 3 located at the periphery of the lower air port 5 are vertically stacked and welded to form an annular welding area, which not only ensures the vertical stacking and fixation of the upper bladder 2 and the lower bladder 3, prevents the two from separating, ensures the smoothness of the air path and enables the adjustment of softness and hardness through inflation and deflation, but also reduces the restriction on the radial swing of the upper bladder 2 by reducing the outer diameter of the welding area, effectively improving the sensitivity of the radial swing of the upper bladder 2. Furthermore, it ensures that the upper bladder 2 realizes the matching and fitting with the user's surface through swinging, improves the reliability of support by increasing the contact area, thereby enhancing the lying comfort, and also ensures that the lower bladder 3 can provide stable support for the upper bladder 2, ensuring that the upper bladder 2 can return to the posture with the axis vertically set by using its own reset pre-tightening force without external force.
[0031] In this embodiment, the ratio of the outer diameter of the welding area to the outer diameter of the unit bladder is B, and B ≤ 0.5. By setting a welding area with reasonable dimensions between the peripheries of the upper air port 4 and the lower air port 5, it not only ensures that the width of the welding area meets the sealing requirements, but also ensures that the diameters of the upper air port 4 and the lower air port 5 meet the requirements for air flow, and also ensures that the ratio of the outer diameter of the welding area to the outer diameter of the unit bladder meets the preset requirements. Furthermore, it ensures that the radial swing of the upper bladder 2 has less resistance, thereby improving the swing flexibility and ensuring that the top surface of the upper bladder 2 can match and fit with the user's surface.
[0032] In this embodiment, the upper bladder 2 includes an upper cover part 6 and an upper cover plate 7. An upper bladder cavity that is open downward is provided inside the upper cover part 6, and the upper cover plate 7 covers the bottom surface of the upper cover part 6 and seals the upper bladder cavity. The airbag strip 1 includes a strip-shaped lower bottom piece 8 and a lower cover plate 9. The peripheries of the lower bottom piece 8 and the lower cover plate 9 are stacked and welded so that the lower bladders 3 are connected into a whole. The upper cover part 6, the upper cover plate 7, the lower bottom piece 8, and the lower cover plate 9 are all integrally formed parts processed independently, which is not only convenient for batch processing of each of them, but also convenient for assembling to form the airbag strip 1. During installation, first, the lower cover plate 9 is covered on the lower bottom piece 8, and welding is performed along the edge of the overlapping area of the two, which not only ensures the fixation of the two, but also can enclose and form a lower bladder cavity that is connected through an air path channel; then, the upper cover part 6 is stacked on the upper cover plate 7 and the periphery of the overlapping area is welded so that the two are fixed and an upper bladder 2 with an upper air port 4 at the bottom is formed; finally, the upper bladder 2 is covered on the corresponding lower bladder 3, and the peripheries of the upper air port 4 and the lower air port 5 are stacked and welded and fixed so that the upper air port 4 and the lower air port 5 are sealed and communicated.
[0033] After being installed in place, the upper bladder bodies 2 are fixedly connected to the corresponding lower bladder bodies 3 independently of each other, and each upper bladder body 2 can swing independently and fit against the user's surface. The lower bladder bodies 3 on the airbag strip 1 are of an integral structure, interconnected and fixedly connected, which can not only improve the stability of supporting the upper bladder bodies 2, but also ensure that the air pressure in each upper bladder body 2 can be adjusted synchronously.
[0034] In this embodiment, the periphery of the upper cover sheet 7 and the periphery of the bottom surface of the upper cover part 6 are hermetically sealed by welding adhesion. The bottom surface of the upper cover part 6 is provided with an opening. The periphery of the opening and the periphery of the upper cover sheet 7 are overlapped and welded and adhered to form a welding area, which is not only convenient for processing, but also effectively improves the sealing reliability. And the welding part is located at the junction of the bottom wall and the side wall of the upper bladder body 2, and cracking and air leakage are prevented by reducing deformation.
[0035] In this embodiment, the upper air port 4 is opened in the middle of the upper cover sheet 7, the lower air port 5 is opened in the middle of the unit cover, the outer diameters of the corresponding unit covers in the upper cover sheet 7 and the lower cover sheet 9 are the same, the diameters of the upper air port 4 and the lower air port 5 are the same, the unit covers on the upper cover sheet 7 and the lower cover sheet 9 are vertically aligned and overlapped, and the peripheral areas of the upper air port 4 and the lower air port 5 are overlapped and welded to form an annular welding area, so that the upper bladder body 2 can swing radially freely with the axis of the lower air port 5 as the center.
[0036] In this embodiment, the upper cover part 6 is integrally injection-molded, which is not only convenient for batch processing, but also ensures that the upper cover part 6 has good sealing performance. In addition, the upper cover sheet 7, the lower cover sheet 9 and the lower bottom surface can also be processed by injection molding, which should all be regarded as the specific implementation manners of this embodiment.
[0037] In this embodiment, the lower bottom sheet 8 includes a unit bottom area 10 arranged in a straight line and an air path bottom area 11 connected between adjacent unit bottom areas 10. The lower cover sheet 9 includes a unit cover area 12 arranged in a straight line and an air path cover area 13 connected between adjacent unit cover areas 12. The peripheries of the unit bottom area 10 and the unit cover area 12 are hermetically sealed by overlapping and welding to form the lower bladder body 3. The side edges of the air path bottom area 11 and the air path cover area 13 are hermetically sealed by welding to form an air path channel straddling between adjacent lower bladder bodies 3. The lower bottom sheet 8 and the lower cover sheet 9 have the same peripheral contour, so that the two can be vertically aligned and overlapped and welded and fixed along the outer edge of the overlapping area. The unit bottom area 10 and the unit cover area 12 are overlapped and enclosed to form the lower bladder body 3 with a lower bladder cavity. The air path bottom area 11 and the air path cover area 13 are overlapped and enclosed to form an air path channel straddling between adjacent lower bladder cavities. A plurality of lower bladder bodies 3 are arranged in a straight line, and the air path channels are arranged between adjacent lower bladder bodies 3. All the air path channels are located on the same straight line, so that the airbag strip 1 is in a strip shape, which is convenient for splicing to form the airbag pad 15.
[0038] In this embodiment, the welding area formed by the superposition of the peripheries of the upper air inlet 4 and the lower air inlet 5 is annular, and 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 outer diameter of its outer edge is reduced, thereby improving the sensitivity of the tilting swing of the upper bladder 2. In addition, the width of the welding area formed by the superposition and welding between the upper cover portion 6 and the upper cover piece 7 and between the lower cover piece 9 and the lower bottom piece 8 should also meet the above requirements.
[0039] In this embodiment, connecting edges 14 are provided on both the front edge and the rear edge of the lower bottom piece 8 (as Figure 3 shown), and adjacent airbag strips 1 are superposed and welded and adhered through the corresponding connecting edges 14. The adjacent airbag strips 1 are superposed and welded and fixed through the corresponding connecting edges 14 so that there is the same spacing between adjacent airbag strips 1, ensuring that the unit bladders on the airbag pad 15 are arranged in a matrix.
[0040] Embodiment Two:
[0041] Compared with Embodiment One, this embodiment provides a mattress.
[0042] As Figure 4 shown, the mattress includes a pad body, and the pad body includes an airbag pad 15 and a limiting block 16 that clamps and wraps the airbag pad 15. The limiting block 16 plays a role in clamping, positioning, and protecting the airbag pad 15, ensuring that the airbag pad 15 is adjusted in softness and hardness by inflating and deflating at a preset position, thereby improving the use comfort of the pad body.
[0043] In this embodiment, perforations are provided on the limiting block 16, and the number and positions of the perforations are matched one by one with the unit bladders on the airbag pad 15. During installation, the limiting block 16 wraps the airbag pad 15, and the perforations are sleeved on the corresponding unit bladders, so that each unit bladder is limited by the inner wall of the perforation, ensuring that the unit bladder realizes vertical expansion and contraction under the guidance of the perforation, and further realizing softness and hardness adjustment by adjusting the air pressure to provide comfortable support for the user.
[0044] The other structures and effects of the airbag pad in this embodiment are the same as those in Embodiment One and will not be elaborated.
