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-to-back direction. The airbag strips include unit airbags arranged in a linear pattern. The unit airbags on the same airbag strip have top surfaces and bottom surfaces at the same height, so that the airbag pad has a flat top surface and a flat bottom surface, thereby providing stable support for the user. The existing unit airbag includes a plurality of vertically stacked air chambers, and each air chamber is formed by enclosing two sheets stacked and welded. When processing the airbag strip, it is necessary to weld the sheets into air chambers, unit airbags, and airbag strips in sequence, resulting in cumbersome processing steps and a large number of stacking and welding processes. There is a greater risk of breakage and air leakage due to a large number of welding areas, which affects the service life of the airbag strip. In addition, the processing time is prolonged due to the cumbersome process, resulting in reduced processing efficiency and affecting the use experience. 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, which are provided with an upper airbag body and a lower airbag body integrally formed. The upper airbag body and the lower airbag body are fixedly adhered through an air path platform, which not only reduces the welding area, but also simplifies the processing steps and improves the use experience.

[0004] The utility model is realized in the following way: an airbag pad includes closely arranged unit airbags. The unit airbags include an upper airbag body and a lower airbag body. The upper airbag body and the lower airbag body are integrally formed. The upper airbag body and the lower airbag body are vertically aligned and welded and adhered through an air path platform provided with an internal air path channel. An air port is provided on the air path channel. The upper airbag body, the air path platform, and the lower airbag body are vertically stacked and adhered and communicated with the air path channel through the air port. By setting the upper airbag body and the lower airbag body integrally formed and fixedly adhered through the air path platform, the welding area is reduced, the risk of breakage and air leakage is effectively reduced, the service life of the airbag pad is prolonged, the processing steps are simplified, the assembly efficiency is improved by reducing the welding area, and the use experience is improved.

[0005] Preferably, the air port is opened in the section of the air path channel corresponding to the unit airbag. The air path channel is connected to each unit airbag through the air port, so that the unit airbag can be communicated through the air path channel, thereby facilitating synchronous inflation and deflation adjustment of the unit airbag.

[0006] Preferably, there are two vertically aligned air ports between the air passage and each unit bladder, and the air passage is connected to the upper bladder and the lower bladder respectively through the corresponding air ports. The air ports are respectively arranged at the top and bottom of the air passage, so that corresponding air ports are provided between the air passage and the upper bladder and between the air passage and the lower bladder, enabling the air pressures in the upper bladder and the lower bladder to be synchronously and precisely adjusted, effectively improving the air charging and discharging efficiency in the unit bladder, ensuring the air pressure balance in each area of the unit bladder, and preventing the unit bladder from being biased and telescoped due to the deviation of the air charging and discharging effects between different areas therein.

[0007] Preferably, the air port is arranged on the axis of the unit bladder. The air port is located on the axis of the unit bladder, making the distances between the air port and each circumferential section of the side wall of the unit bladder the same, ensuring that the unit bladder can be precisely telescoped along its axis, preventing the occurrence of biased telescoping, and ensuring that the top surface of the unit bladder can be telescopically extended and retracted in a horizontal posture.

[0008] Preferably, the air passage platform includes an upper sheet and a lower sheet, and the upper sheet and the lower sheet are vertically stacked and welded and adhered. The upper sheet and the lower sheet are independently processed and stacked and adhered to form the air passage platform. Both the upper sheet and the lower sheet are single-layer thin sheets, which is not only convenient for batch processing but also convenient for stacking and welding to form the air passage platform with an internal air passage, and further convenient for welding and fixing the upper bladder and the lower bladder.

[0009] Preferably, air passage grooves are respectively provided on the upper sheet and the lower sheet, and the air passage grooves are vertically stacked and enclosed to form the air passage. The air passage grooves are pre-formed during processing, which is not only convenient for processing, effectively simplifies the processing steps, but also can enclose the air passage by stacking the air passage grooves, ensuring that the cross-sectional area of the air passage meets the requirements of air flow transportation and improving the air pressure adjustment efficiency in the unit bladder.

[0010] Preferably, welding areas are arranged along the edges of the air passage grooves on the upper sheet and the lower sheet, and the width of the welding area is A, A≥5mm. This not only improves the sealing reliability by increasing the width of the welding area to prevent the occurrence of breakage and air leakage, but also reduces the welding operation amount by restricting the width of the welding area, thereby improving the processing efficiency. The welding areas are arranged along the edges of the air passage grooves, which not only ensures the firm connection between the upper sheet and the lower sheet, but also prevents the air flow from overflowing from the air passage grooves and causing local inflation and expansion of the upper sheet and the lower sheet, ensuring that the air passage platform always has a flat sheet structure and enabling the upper bladder and the lower bladder to be coaxially arranged with each other.

[0011] Preferably, the gas path channel includes a main channel provided with a gas nozzle and auxiliary channels communicating with the main channel. The auxiliary channels are arranged in parallel with each other, and a number of unit capsules arranged in a straight line are connected in series in the auxiliary channels. The main channel is connected to both the external gas source and each auxiliary channel, and each auxiliary channel is connected to both the main channel and each unit capsule along the way, so that the air pressure in each unit capsule on the gas path channel can be adjusted synchronously, which not only simplifies the structure of the gas path channel and facilitates laying, but also simplifies the control difficulty and facilitates operation control.

[0012] Preferably, at least two independent gas path channels are provided on the gas path platform. The gas nozzles are arranged at the edge of the gas path platform and are connected to the external gas source, so that the air pressure in the unit capsules on the gas path channel can be adjusted synchronously. The gas path platform is used to fix the unit capsules, and the unit capsules in different regions are connected through corresponding gas path channels, so that partitions corresponding to the number of gas path channels are formed on the gas path platform, and the air pressure between the partitions can be adjusted differentially, providing users with diversified usage schemes and improving the usage comfort.

[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 usage comfort of the pad body.

[0014] The beneficial effects of the present utility model: The upper airbag body and the lower airbag body are integrally formed and fixedly adhered through the gas path platform, 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 enhances the usage experience.

[0021] The following further explains the substantial features of the present utility model in conjunction with the accompanying drawings of the specification and the detailed implementation manner.

[0022] Embodiment 1:

[0023] This embodiment provides an airbag pad.

[0024] As Figure 1 and 2 shown, an airbag pad includes closely arranged unit airbags. The unit airbag includes an upper capsule body 1 and a lower capsule body 2. The upper capsule body 1 and the lower capsule body 2 are integrally formed by processing. The upper capsule body 1 and the lower capsule body 2 are vertically aligned and welded and adhered through an air passage platform 3 provided with an air passage 4 inside. An air port 5 is provided on the air passage 4. The upper capsule body 1, the air passage platform 3, and the lower capsule body 2 are vertically stacked and adhered and communicated with the air passage 4 through the air port 5. By setting the integrally formed upper capsule body 1 and lower capsule body 2, and the upper capsule body 1 and the lower capsule body 2 are fixedly adhered through the air passage platform 3, it not only reduces the welding area, effectively reduces the risk of breakage and air leakage, prolongs the service life of the airbag pad 12, but also simplifies the processing steps, and improves the assembly efficiency and the use experience by reducing the welding area.

[0025] In this embodiment, the upper capsule body 1, the lower capsule body 2, the upper placed sheet 6, and the lower placed sheet 7 are all integrally formed by processing. 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 capsule body 1 and the lower capsule body 2 are sealed, and all should be regarded as the specific implementation manners of this embodiment.

[0026] In this embodiment, since the upper capsule body 1, the lower capsule body 2, the upper placed sheet 6, and the lower placed sheet 7 are all of an integrated structure, when processing and producing the unit airbag, it is necessary to perform three welding operations between the upper capsule body 1 and the upper placed sheet 6, between the upper placed sheet 6 and the lower placed sheet 7, and between the lower placed sheet 7 and the lower capsule body 2 to achieve assembly. It not only effectively reduces the welding area, thereby reducing the risk of breakage and air leakage in the welding area, but also shortens the assembly production time and improves the production efficiency. The upper placed sheet 6 and the lower placed sheet 7 can be pre-opened with air ports 5 according to the layout requirements of the unit airbag during processing to facilitate subsequent assembly.

[0027] During assembly, welding operations need to be performed separately between the upper bladder 1 and the upper sheet 6, between the upper sheet 6 and the lower sheet 7, and between the lower sheet 7 and the lower bladder 2. The upper bladder 1 and the lower bladder 2 are assembled through the shared air path platform 3 to form the airbag pad 12, which not only ensures the relative position of the unit bladders is fixed but also facilitates the unified inflation and deflation operations of each unit bladder along the way through the air path channel 4.

[0028] In this embodiment, the air path platform 3 includes the upper sheet 6 and the lower sheet 7 (as Figure 3 shown), and air path grooves 8 are respectively provided on the upper sheet 6 and the lower sheet 7. The upper sheet 6 and the lower sheet 7 are vertically stacked and welded, and the air path grooves 8 are vertically stacked and enclose to form the air path channel 4. By setting the air path grooves 8, it is ensured that the cross-sectional profile of the air path channel 4 meets the air flow rate requirements, thereby improving the air pressure regulation efficiency and accuracy in the unit bladder. During welding, the welding areas are arranged along the edges of the air path grooves 8 on the upper sheet 6 and the lower sheet 7. The welding areas are arranged along the edges of the air path grooves 8, which not only ensures the air flow along the air path grooves 8 but also effectively maintains the cross-sectional profile shape of the air path grooves 8, ensuring that the air flow does not overflow from the air path grooves 8 and preventing the upper sheet 6 and the lower sheet 7 from expanding and deforming due to local inflation.

[0029] In this embodiment, the upper bladder 1 and the lower bladder 2 are vertically stacked and clamp the air path platform 3, so that the air path channel 4 is connected to the unit bladder through the air port 5. The peripheral edge of the bottom surface of the upper bladder 1 is fixedly attached to the top surface of the air path platform 3, and the peripheral edge of the top surface of the lower bladder 2 is fixedly attached to the bottom surface of the air path platform 3. The air port 5 is opened in the section of the air path channel 4 corresponding to the unit bladder to ensure the connection between the upper bladder 1, the lower bladder 2, and the air path channel 4 through the air port 5.

[0030] In this embodiment, two vertically aligned air ports 5 are provided between the air path channel 4 and each unit bladder. The air path channel 4 is connected to the upper bladder 1 and the lower bladder 2 respectively through the corresponding air ports 5. The air port 5 is arranged at the axis of the unit bladder. The top wall and the bottom wall of the air path channel 4 are respectively provided with the air port 5 along the axis of the corresponding unit bladder, so that the air ports 5 are vertically aligned and are respectively connected to the upper bladder 1 and the lower bladder 2, ensuring that the air path channel 4 is respectively connected to the upper bladder 1 and the lower bladder 2 through the air ports 5, and also ensuring that the upper bladder 1 and the lower bladder 2 are connected to each other through the air ports 5, which is convenient for the unified regulation of the air pressure in the unit bladder. Specifically, the upper bladder 1 and the corresponding air port 5 are coaxially arranged, and the peripheral edge of the bottom surface of the upper bladder 1 is closely attached to and welded to the peripheral edge area of the corresponding air port 5 on the top surface of the air path platform 3 to ensure the sealed connection between the peripheral edge of the bottom surface of the upper bladder 1 and the upper sheet 6. Similarly, the lower bladder 2 and the bottom surface of the lower sheet 7 are hermetically connected through close fitting and welding.

[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 gas path channel 4 includes a main channel 9 provided with a gas nozzle 11 and a sub-channel 10 communicating with the main channel 9. The sub-channels 10 are arranged in parallel with each other, and the sub-channels 10 are connected in series with a number of unit bladders arranged in a straight line. The unit bladders arranged in multiple rows are connected through the gas path channel 4. The unit bladders in the same row are connected in series through the sub-channel 10, and the sub-channels 10 of the adjacent row of unit bladders are connected through the main channel 9, so that the unit bladders in a matrix shape can be uniformly inflated and deflated by the same gas path channel 4, thereby realizing the adjustment of softness and hardness.

[0033] In this embodiment, at least two independent gas path channels 4 are provided on the gas path platform 3 (as Figure 4 shown), and the gas nozzles 11 are provided at the edge of the gas path platform 3 and are connected to an external gas source, so that the air pressure of the unit bladders on the gas path channel 4 can be adjusted synchronously. The gas path platform 3 controls different groups of unit bladders by providing a plurality of independent and controllable gas path channels 4, so that the unit bladders are divided into multiple independently controllable zones, providing users with a diversified support experience.

[0034] Embodiment Two:

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

[0036] As Figure 5 shown, the mattress includes a mattress body, and the mattress body includes an airbag pad 12 and a limiting block 13 that clamps and wraps the airbag pad 12. The limiting block 13 plays a role in clamping, positioning and protecting the airbag pad 12, ensuring that the airbag pad 12 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, the limiting block 13 is provided with through holes, and the number and positions of the through holes are matched one by one with the unit bladders on the airbag pad 12. During installation, the limiting block 13 wraps the airbag pad 12, and the through holes are sleeved on the corresponding unit bladders, so that each unit bladder is limited by the inner wall of the through hole, ensuring that the unit bladder realizes vertical expansion and contraction under the guidance of the through hole, and then adjusting the softness and hardness by adjusting the air pressure, providing comfortable support for users.

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