Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly 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 each airbag strip can be synchronously adjusted, and further, when the adjacent airbag strips are communicated with each other, the air pressure is synchronously adjusted. The existing air passage channel is formed by connecting the pipe orifices extending outward from the capsule component assemblies. The capsule component assemblies form the pipe orifices during assembly and processing. The corresponding pipe orifices of the adjacent capsule component assemblies are hermetically fixed by direct welding or by providing a connecting pipe. This not only affects the production efficiency due to the troublesome processing, but also is prone to breakage and air leakage due to a large number of welding areas, affecting the use experience. Summary 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 air pipe sequentially passes through each capsule component assembly to form an airbag strip. The air pipe is communicated with each capsule component assembly through a ventilation hole to form an air passage channel, which not only simplifies the processing operation, improves the production efficiency, but also uses a whole air pipe to ensure the airtightness along the way, reduces the risk of air leakage, and improves 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 and an air pipe connecting the capsule component assemblies in series. Ventilation holes are opened in the sections of the air pipe located in each capsule component assembly, so that the inner cavities of the capsule component assemblies are communicated through the air pipe. The air pipe sequentially passes through each capsule component assembly to form a straight airbag strip. Ventilation holes are provided in the sections of the air pipe located in each capsule component assembly, so that the capsule component assemblies in the airbag strip are communicated through the air pipe. The air pipe connects the capsule component assemblies in series and forms an air passage channel that does not require welding and assembly, which not only simplifies the processing operation, improves the production efficiency, but also uses a whole air pipe to ensure good airtightness of the section of the air pipe between adjacent capsule component assemblies, reduces the risk of air leakage, and improves the use experience.

[0005] Preferably, the capsule component assembly includes an upper cover part and a lower cover part. The upper cover part and the lower cover part vertically clamp the air pipe and enclose to form an inner cavity isolated from the outside. The inner cavity is communicated with the outside through the corresponding ventilation hole, so that the capsule component assembly vertically expands and contracts to adjust the support property. The upper cover part and the lower cover part are independently processed and assembled to form a capsule component assembly. The upper cover part and the lower cover part are stacked and clamped on the air pipe and welded and fixed, which not only ensures that a sealed inner cavity can be enclosed between the upper cover part and the lower cover part, but also ensures that the inner cavity is connected to the air pipe through the ventilation hole, so that the inner cavities connected in series on the air pipe are communicated with each other, facilitating synchronous adjustment of the air pressure.

[0006] Preferably, the upper and lower cover portions are symmetrically structured, each of which is provided with an upper groove and a lower groove extending in opposite directions. The upper and lower cover portions are vertically aligned, stacked, and welded to form a seal, so that the upper and lower grooves enclose the inner cavity. The symmetrical arrangement of the upper and lower cover portions and their identical structure facilitates mass production and eliminates the need for differentiation during assembly, preventing assembly errors and effectively improving assembly efficiency. Once installed, the notches of the upper and lower grooves align and connect to form the inner cavity.

[0007] Preferably, upper notches are provided on both sides of the notch periphery of the upper groove, and lower notches are provided on both sides of the notch periphery of the lower groove. The upper and lower notches are aligned and overlapped, tightly wrapping the trachea, so that the trachea, the upper notches, and the lower notches are welded and sealed. The upper and lower notches are vertically aligned and clamp the trachea, ensuring that the trachea can pass smoothly through the bladder assembly and effectively eliminating the gap between the bladder assembly and the trachea, facilitating a sealed connection via welding.

[0008] Preferably, the edges of the notches of the upper and lower grooves are flat, so that the bottom surface of the upper cover part and the top surface of the lower cover part fit tightly together, thereby improving the sealing performance and facilitating welding operations by eliminating the gap between the notches of the upper and lower grooves.

[0009] Preferably, the upper groove and the lower groove have differentiated depths. By setting upper grooves and lower grooves of different depths, differentiated bladder assemblies are obtained, so that the bladder assembly can be adjusted and replaced according to usage requirements, thereby adjusting the insertion position of the trachea on the airbag assembly to improve the usage experience.

[0010] Preferably, the vent is opened in the middle of the trachea in the inner cavity section, and the vent is arranged in the middle of the inner cavity to ensure that the air pressure in the inner cavity can be accurately adjusted.

[0011] Preferably, there are two vents, which are opened toward the upper trough and the lower trough respectively, to ensure that the air pressure in the upper trough and the lower trough can be accurately adjusted.

[0012] Preferably, the side of the bladder assembly is provided with a contact portion extending along the direction of the tracheal arrangement. Adjacent bladder assemblies are positioned against each other by the corresponding contact portion, thereby fixing the relative position of the adjacent bladder assemblies. The contact portion is integrally formed with the bladder assembly, which not only facilitates processing but also ensures uniform structure and dimensions of the contact portion, improving positioning accuracy. Adjacent bladder assemblies are positioned against each other by the contact portion, ensuring a constant distance between them and facilitating quick assembly.

[0013] Preferably, the end of the trachea is exposed outside the end of the airbag strip to form an air port communicating with the outside. The trachea is connected to the outside through the air port, which not only facilitates the communication between adjacent airbag strips through the air port to realize the synchronous adjustment of air pressure, but also facilitates the connection of the airbag strip to an external air source through the air port to realize the precise adjustment of the air pressure in each bladder assembly.

[0014] 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.

[0015] The beneficial effects of the present utility model are as follows: The trachea sequentially passes through each bladder assembly to form a linear airbag strip. Ventilation holes are provided on the sections of the trachea located in each bladder assembly, so that the bladder assemblies in the airbag strip are connected through the trachea. The trachea connects each bladder assembly in series to form an air passage that does not require welding and assembly, which not only simplifies the processing operation and improves production efficiency, but also uses a whole trachea to ensure that the section of the trachea between adjacent bladder assemblies has good sealing performance, reduces the risk of air leakage, and improves the use experience.

[0023] The following further describes the substantial features of the present utility model in conjunction with the accompanying drawings of the specification and the 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 bladder components 2 arranged linearly and air tubes 3 connecting the bladder components 2 in series. Ventilation holes 4 are provided in the sections of the air tubes 3 located inside each bladder component 2, so that the inner cavities of the bladder components 2 are connected through the air tubes 3. The air tube 3 passes through each bladder component 2 in sequence to form a linear airbag strip 1. Ventilation holes 4 are provided in the sections of the air tube 3 located inside each bladder component 2, enabling the bladder components 2 inside the airbag strip 1 to be connected through the air tube 3. The air tube 3 connects the bladder components 2 in series to form an air path channel that does not require welding and assembly, which not only simplifies the processing operation and improves production efficiency, but also uses a whole air tube 3 to ensure good sealing of the section of the air tube 3 between adjacent bladder components 2, reducing the risk of air leakage and enhancing the user experience.

[0027] In this embodiment, the bladder component 2 includes an upper cover part 5 and a lower cover part 6 (as Figure 3 shown). The upper cover part 5 and the lower cover part 6 clamp the air tube 3 vertically and enclose an inner cavity isolated from the outside. The inner cavity is connected to the outside through the corresponding ventilation holes 4, so that the bladder component 2 can expand and contract vertically to adjust the supportability. When processing the airbag strip 1, first, an air tube 3 matching the length of the airbag strip 1 is intercepted, and the ventilation holes 4 are provided on the air tube 3; then, the upper cover part 5 and the lower cover part 6 are stacked vertically and clamp the air tube 3, so that the corresponding ventilation holes 4 on the air tube 3 are wrapped in the inner cavity formed by the upper cover part 5 and the lower cover part 6; then, the stacked area between the upper cover part 5, the lower cover part 6 and the air tube 3 is welded to form a sealed welding area; finally, the bladder components 2 are arranged and installed along the air tube 3 in sequence, so that the air tube 3 is connected to the inner cavities of the bladder components 2 through the ventilation holes 4.

[0028] After the installation is completed, the air ports 12 at the ends of the air tube 3 are exposed at the ends of the airbag strip 1, and the ventilation holes 4 on the air tube 3 are all wrapped in the inner cavities of the corresponding bladder components 2, so that the bladder components 2 inside the airbag strip 1 are connected to the air tube 3 through the ventilation holes 4, and further the bladder components 2 on the airbag strip 1 are connected to the outside air tube 3 through the air tube 3, ensuring that the air pressures of the bladder components 2 inside the airbag strip 1 can be adjusted synchronously.

[0029] In this embodiment, the end of the trachea 3 is exposed outside the end of the airbag strip 1 to form an air port 12 communicating with the outside. The airbag strip 1 is connected to an external air source through the air port 12, so that the airbag strip 1 can achieve air pressure regulation and control through inflation and deflation operations. During use, the air ports 12 between adjacent airbag strips 1 can be connected through pipelines, so that the air pressures inside the adjacent airbag strips 1 can be adjusted synchronously, thereby enabling the softness and hardness of the locally connected or overall area inside the airbag pad 13 to be adjusted synchronously. One end of the trachea 3 is located at one end of the airbag strip 1 to form an air port, and the other end is located at the other end of the airbag strip 1 and is blocked, ensuring that the trachea 3 can only communicate with the outside through the air port 12.

[0030] In this embodiment, the upper cover part 5 and the lower cover part 6 have a symmetrical structure, so that the upper cover part 5 and the lower cover part 6 have the same structure, which not only facilitates large-scale production, but also eliminates the need to distinguish parts during assembly, facilitating quick assembly. In addition, the upper groove 7 and the lower groove 8 have different depths, which can not only adjust the threading position of the trachea 3 on the bladder assembly 2, for example, setting the trachea 3 at the bottom of the bladder assembly 2 to ensure that the trachea 3 will not be squeezed and blocked on the premise of ensuring the lifting range of the top of the bladder assembly 2, but also can assemble various bladder assemblies 2 that meet the usage requirements, effectively expanding the applicable range of the series connection structure of the trachea 3. All of these should be regarded as specific implementation manners of this embodiment.

[0031] In this embodiment, upper grooves 7 and lower grooves 8 are oppositely formed inside the upper cover part 5 and the lower cover part 6. The upper cover part 5 and the lower cover part 6 are vertically aligned and stacked and welded and sealed, so that the upper grooves 7 and the lower grooves 8 enclose to form the inner cavity. The welding method is ultrasonic welding or high-frequency welding to ensure good sealing performance at the welding part.

[0032] In this embodiment, upper notches 9 are provided on both sides of the peripheral edge of the notch of the upper groove 7, and lower notches 10 are provided on both sides of the peripheral edge of the notch of the lower groove 8. The upper notches 9 and the lower notches 10 are aligned and stacked and tightly wrap the trachea 3, so that the trachea 3, the upper notches 9 and the lower notches 10 are welded and sealed. There are two upper notches 9, which are symmetrically arranged with the axis of the upper cover part 5 as the center. The cross-sectional contour of the upper notch 9 is arc-shaped and corresponds to the outer diameter of the trachea 3, ensuring that the outer wall of the trachea 3 can fit with the inner wall of the upper notch 9, which not only facilitates welding and sealing, but also prevents the trachea 3 from being squeezed and deformed with the upper cover notch, ensuring that the cross-sectional area of the trachea 3 meets the requirements of the air flow rate. The lower notch 10 has the same structure as the upper notch 9 and can also play a role in sealing connection and preventing the trachea 3 from being squeezed.

[0033] In this embodiment, the edges of the upper and lower grooves 7 and 8 are flat, allowing the bottom surface of the upper cover portion 5 to fit tightly against the top surface of the lower cover portion 6. The cross-sectional profiles of the upper and lower notches 9 and 10 are semicircular, so that when the air pipe 3 is clamped between the upper and lower notches 9 and 10, the edges of the upper and lower grooves 7 and 8 can match and fit together, thereby facilitating welding and sealing.

[0034] In this embodiment, the vent holes 4 are provided in the middle of the trachea 3 in the inner cavity section. There are two vent holes 4, one facing the upper groove 7 and the other facing the lower groove 8. The vent holes 4 are provided in the middle of the inner cavity to ensure that they can deliver air to all areas of the inner cavity, thereby ensuring that the air pressure in each area of the inner cavity can be synchronously regulated, thereby preventing the bladder assembly 2 from tilting horizontally during expansion and contraction due to asynchronous inflation and deflation of air in each area of the inner cavity.

[0035] In this embodiment, the side of the bladder assembly 2 is provided with a contact portion 11 extending along the direction in which the trachea 3 is set. Adjacent bladder assemblies 2 are positioned by contacting each other through the corresponding contact portions 11, so that the relative positions of adjacent bladder assemblies 2 are fixed. The bottom surface of the upper cover portion 5 and the top surface of the lower cover portion 6 extend to both sides to form the contact portion 11, and the contact portion 11 extends along the direction in which the trachea 3 is set. This can not only increase the axial length of the upper notch 9 and the lower notch 10, thereby improving the sealing reliability by increasing the width of the welding area, but also achieve contact limiting through the contact portion 11 after the bladder assembly 2 clamps the trachea 3, ensuring that the distance between adjacent bladder assemblies 2 is the same.

[0036] In this embodiment, adjacent airbag strips 1 are fixed by overlapping and welding the corresponding leading and trailing edges so that the adjacent airbag strips 1 have the same spacing (eg Figure 4 As shown), it is ensured that the airbag cushion 13 has the bag components 2 arranged in a matrix shape.

[0037] Embodiment 2:

[0038] Compared with the first embodiment, this embodiment provides a mattress.

[0039] like Figure 5 As shown, the mattress includes a cushion body, which includes an airbag cushion 13 and a stopper 14 that clamps and encloses the airbag cushion 13. The stopper 14 clamps, positions, and protects the airbag cushion 13, ensuring that the airbag cushion 13 is adjusted in a preset position by inflation and deflation, thereby improving the comfort of the cushion body.

[0040] In this embodiment, the limit block 14 is provided with perforations, and the number and position of the perforations are matched one by one with the bladder components 2 on the airbag cushion 13. When installed, the limit block 14 wraps the airbag cushion 13, and the perforations are placed on the corresponding bladder components 2, so that each bladder component 2 is limited by the inner wall of the perforations (such as Figure 6As shown, ensure that the bladder assembly 2 realizes vertical expansion and contraction under the guidance of the perforation, and then adjusts the softness and hardness by adjusting the air pressure to provide comfortable support for the user.

[0041] The other structures and effects of the airbag pad in this embodiment are the same as those in the first embodiment and will not be described in detail.
