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 pads include airbag strips arranged closely in the front-back direction. The airbag strips include airbag bodies arranged in a linear shape. The airbag bodies 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 users. The existing airbag strips are formed by welding multiple airbag bodies. Each airbag body 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 strips, the sheets need to be welded into air chambers, airbag bodies, and airbag strips in sequence, resulting in cumbersome processing steps. Especially when processing the airbag bodies, the sheets need to be welded one by one, resulting in an increased welding workload. 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 strips. In addition, the processing time is prolonged due to the cumbersome process, resulting in a reduction in processing efficiency and affecting the use experience. Summary 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 airbag body is integrally formed by thermoforming and is provided with an air chamber with adjustable air pressure, which not only reduces the welding workload, improves the production efficiency, but also ensures the sealing reliability of the airbag body wall surface, and simplifies the processing steps, thus enhancing the use experience.

[0004] The utility model is realized in the following way: An airbag pad includes closely arranged airbag bodies. Each airbag body includes an air chamber integrally formed by thermoforming. An air passage is formed by extending outward from the side of the airbag body, so that the airbag body is communicated with the outside through the air passage. The airbag body is integrally formed by thermoforming. An air chamber is arranged inside the airbag body. The air chamber is communicated with the outside through the air passage to adjust the air pressure, which not only reduces the welding workload, effectively reduces the risk of breakage and air leakage, and prolongs the service life of the airbag pad, but also ensures the sealing reliability of the airbag body wall surface, and simplifies the processing steps, and improves the production efficiency by reducing the welding area, thus enhancing the use experience. The airbag body is formed by thermoforming, which is convenient for batch production and ensures that the quality of the airbag body meets the use requirements.

[0005] Preferably, adjacent airbag bodies are hermetically communicated through corresponding air passages, so that the air pressure inside the airbag bodies can be adjusted synchronously. The air passage not only functions to communicate the air chambers inside adjacent airbag bodies to ensure that the air pressure inside the airbag bodies can be adjusted synchronously, but also plays a role in connecting and positioning adjacent airbag bodies to ensure that the relative positions of adjacent airbag bodies are fixed.

[0006] Preferably, the bladder body includes two air channels disposed on both sides, and the air channels are symmetrically arranged along the diameter line of the bladder body, so that the bladder bodies are connected in series through the air channels to form a linear airbag strip. Adjacent bladder bodies are fixedly welded through the corresponding air channels. There are two air channels and they are disposed on both sides of the bladder body to ensure that the bladder bodies can be connected in series along a straight line to form the airbag strip, ensuring that the airbag strip is linear and facilitating the side-by-side splicing of the airbag strips to form an airbag pad.

[0007] Preferably, the corresponding air channels between adjacent bladder bodies are connected by a connecting pipe, so that the bladder cavities of adjacent bladder bodies communicate with each other. The connecting pipe is bridged between the corresponding air channels, which not only ensures the mutual connection of the corresponding air channels, and then ensures the mutual connection of the bladder cavities of adjacent bladder bodies, but also ensures that the distance between adjacent bladder bodies can be adjusted as needed, and a connecting pipe with a length meeting the use requirements is configured, so that the bladder bodies can be provided with air channels of a unified specification, facilitating mass production and rapid assembly.

[0008] Preferably, the end of the connecting pipe is inserted into the corresponding air channel, and the insertion depth of the connecting pipe is A, and A≥5mm. The connecting pipe is inserted into the corresponding air channel to form an annular overlapping area, and the overlapping area is welded to form a welding area, and the width of the welding area is greater than or equal to 5mm. This not only improves the sealing reliability by increasing the width of the welding area to prevent breakage and air leakage, but also reduces the welding operation amount by restricting the width of the welding area, thereby improving the processing efficiency.

[0009] Preferably, the corresponding air channels are sleeved on both ends of the connecting pipe and are axially abutted and positioned towards each other, so that the distance between adjacent bladder bodies is constant and the connecting pipe is completely blocked. The adjacent air channels are sleeved on both ends of the connecting pipe and axially abutted and positioned through the end faces. This not only ensures that the distance between adjacent bladder bodies is associated with the length of the air channel, ensuring that the distance between adjacent bladder bodies is the same, but also can increase the welding area by increasing the width of the overlapping area between the inner wall of the air channel and the outer wall of the connecting pipe, thereby improving the sealing reliability, and can also use the air channel to block the connecting pipe to improve the aesthetics.

[0010] Preferably, an annular connecting piece is provided on the periphery of the middle part of the bladder body, and a front edge part and a rear edge part are provided on the connecting piece. Adjacent airbag strips are closely arranged in the front-rear direction and are overlapped, welded and adhered through the corresponding front edge parts and rear edge parts. The adjacent bladder bodies are overlapped and welded through the corresponding edges of the connecting piece to ensure the relative position fixation between the adjacent bladder bodies.

[0011] Preferably, an air nozzle connected to an external air source is provided at the air channel at the end of the airbag strip. The bladder bodies on the airbag strip communicate with each other, and the airbag strip communicates with the external air source through the air nozzle, so that the air pressure of each bladder body on the airbag strip can be adjusted through the air nozzle, and further ensure that the soft hardness of each bladder body can be adjusted synchronously.

[0012] Preferably, the side wall of the bladder cavity is provided with an annular crease arranged alternately with concavities and convexities, and the side wall of the bladder cavity is folded along the crease to guide the vertical telescopic deformation of the bladder cavity. By setting the crease to guide the telescopic deformation of the bladder cavity along a preset direction, it not only ensures that the softness and hardness of the bladder cavity can be adjusted, but also ensures that the bladder cavity can accurately reciprocate and apply a force in the preset direction.

[0013] A mattress using the airbag pad includes a pad body, and the pad body includes an airbag pad and a limit block that clamps and wraps the airbag pad. The limit block plays a role in clamping, positioning and protecting the airbag pad, ensuring that the airbag pad is adjusted in softness and 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 invention are as follows: The bladder is integrally formed by vacuum forming, and a bladder cavity is provided inside the bladder. The bladder cavity is connected to the outside air through an air passage and the air pressure is adjusted. This not only reduces the welding workload, effectively reduces the risk of breakage and air leakage, extends the service life of the airbag pad, but also ensures the sealing reliability of the bladder wall surface. Moreover, it simplifies the processing steps, improves the production efficiency by reducing the welding area, and enhances the use experience. The bladder is formed by vacuum forming, which is convenient for batch production and ensures that the quality of the bladder meets the use requirements. Description of the Drawings

[0022] The following further illustrates the substantial features of the present invention in conjunction with the drawings of the specification and the detailed embodiments.

[0023] Embodiment 1:

[0024] This embodiment provides an airbag cushion.

[0025] As Figure 1 and 2 shown, an airbag cushion includes closely arranged bladder bodies 1. The bladder body 1 includes a bladder cavity integrally formed by thermoforming. An air passage 2 extending outward is provided on the side of the bladder body 1, so that the bladder body 1 communicates with the outside through the air passage 2. The bladder body 1 is integrally formed by thermoforming. A bladder cavity is provided inside the bladder body 1, and the bladder cavity communicates with the outside air through the air passage 2 to adjust the air pressure. This not only reduces the welding workload, effectively reduces the risk of breakage and air leakage, extends the service life of the airbag cushion 8, but also ensures the sealing reliability of the wall surface of the bladder body 1. Moreover, it simplifies the processing steps and improves the production efficiency by reducing the welding area, enhancing the user experience. The bladder body 1 is formed by thermoforming, which is convenient for mass production and ensures that the quality of the bladder body 1 meets the usage requirements.

[0026] In this embodiment, the bladder body 1 is integrally processed and formed, and its processing method is thermoforming or the like. This is not only convenient for mass processing, avoids the processing of stacking and welding sheets one by one through integral forming, effectively shortens the processing time, improves the production efficiency, but also ensures that the wall surface of the bladder body 1 is continuous and has good sealing performance.

[0027] In this embodiment, the bladder body 1 includes a built-in bladder cavity and two air passages 2 disposed on both sides. One end of the air passage 2 communicates with the bladder cavity, and the other end is open. During assembly, adjacent bladder bodies 1 are first welded and communicated through the corresponding air passages 2, then the corresponding edges are stacked and welded through the connecting piece 4. Finally, the bladder bodies 1 are sequentially connected in series as required to form an airbag strip 5 including a preset number of bladder bodies 1, which is convenient for subsequent splicing and use.

[0028] In this embodiment, adjacent bladder bodies 1 are hermetically communicated through the corresponding air passages 2, so that the air pressure inside the bladder bodies 1 can be adjusted synchronously. The air passages 2 are symmetrically arranged along the radial line of the bladder body 1, so that the bladder bodies 1 are connected in series through the air passages 2 to form a linear airbag strip 5. By setting symmetric air passages 2 on the bladder body 1, it is ensured that the bladder bodies 1 can be arranged in a straight line and connected in series to form a long strip-shaped airbag strip 5 (as Figure 3 shown), which is convenient for the airbag strip 5 to be formed into an airbag cushion 8 by juxtaposing and joining.

[0029] In this embodiment, adjacent corresponding air passages 2 of the bladder bodies 1 are connected by a connecting pipe 3, so that the bladder cavities of adjacent bladder bodies 1 communicate with each other. The corresponding air passages 2 are sleeved at both ends of the connecting pipe 3 and are positioned by abutting against each other, so that the distance between adjacent bladder bodies 1 is constant and the connecting pipe 3 is completely blocked. The two end portions of the connecting pipe 3 are respectively inserted into the corresponding air passages 2, which can not only increase the width of the welding area, improve the sealing effect, but also play a role in blocking the connecting pipe 3, improving the aesthetics. Moreover, it can utilize the air passages 2 with the same length to abut against each other, play a role in positioning adjacent bladder bodies 1, ensure that the distance between adjacent bladder bodies 1 remains the same, and is convenient for rapid assembly.

[0030] In this embodiment, the end of the connecting pipe 3 is inserted into the corresponding air duct 2, and the insertion depth of the connecting pipe 3 is A, where A ≥ 5 mm. The outer wall of the end of the connecting pipe 3 and the inner wall of the air duct 2 are overlapped and welded to form a welding area, and the width of the welding area is not less than 5 mm. By increasing the width of the welding area, the sealing reliability is improved, and by limiting the width of the welding area, the area of the welding area is reduced, thereby shortening the processing time and improving the production efficiency.

[0031] In this embodiment, a circular connecting piece 4 is provided on the periphery of the middle part of the bladder 1 (as Figure 4 shown), and a leading edge part and a trailing edge part are provided on the connecting piece 4. The adjacent airbag strips 5 are closely arranged in the front-rear direction and are overlapped and welded and adhered through the corresponding leading edge part and trailing edge part. The connecting piece 4 is annular and is arranged around the middle part of the bladder 1, which not only facilitates the side edges of the adjacent bladders 1 to be overlapped and welded through the connecting piece 4 to form the strip-shaped airbag strips 5, but also facilitates the adjacent airbag strips 5 to be overlapped and welded through the front and rear edges of the connecting piece 4 to form the airbag pad 8 (as Figure 5 shown), ensuring that the bladders 1 in the airbag pad 8 are arranged in a matrix.

[0032] In this embodiment, at the air duct 2 located at the end of the airbag strip 5, an air nozzle 6 connected to an external air source is provided, so that the bladders 1 on the same airbag strip 5 can all achieve unified air pressure adjustment through the air nozzle 6. The air nozzles 6 of the adjacent airbag strips 5 are connected to achieve synchronous air pressure adjustment, so that the adjacent airbag strips 5 form partitions with synchronous adjustment of softness and hardness, and the coverage area is adjusted by adjusting the number of airbag strips 5. The airbag pad 8 is formed by splicing multiple partitions, so that the softness and hardness of each partition of the airbag pad 8 can be independently adjusted, improving the use comfort.

[0033] In this embodiment, the side wall of the bladder cavity is provided with an annular crease 7 with alternating concave and convex parts, and the side wall of the bladder cavity is folded along the crease 7 to guide the vertical telescopic deformation of the bladder cavity. The crease 7 can guide the axial telescopic deformation of the bladder cavity during inflation and deflation, which not only ensures that the deformation mode of the bladder cavity during inflation and deflation is fixed, preventing mutual interference between adjacent bladders 1, but also ensures that the bladder cavity can accurately deform reciprocally to accurately adjust the softness and hardness of the bladder 1.

[0034] Embodiment Two:

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

[0036] As Figure 6 shown, the mattress includes a pad body, and the pad body includes an airbag pad 8 and a limiting block 9 that clamps and wraps the airbag pad 8. The limiting block 9 plays a role in clamping, positioning and protecting the airbag pad 8, ensuring that the airbag pad 8 is adjusted in softness and hardness by inflation and deflation at a preset position, thereby improving the use comfort of the pad body.

[0037] In this embodiment, the limiting block 9 is provided with perforations, and the number and positions of the perforations are in one-to-one correspondence with the capsules 1 on the airbag pad 8. During installation, the limiting block 9 wraps the airbag pad 8, and the perforations are sleeved on the corresponding capsules 1, so that each capsule 1 is limited by the inner wall of the perforation, ensuring that the capsule 1 realizes vertical expansion and contraction under the guidance of the perforation, and further adjusting the softness and hardness by adjusting the air pressure to provide comfortable support for the user.

[0038] Other structures and effects of the airbag pad in this embodiment are the same as those in Embodiment 1 and will not be elaborated herein.
