[0002] The existing mattress includes an airbag cushion, which includes airbag strips tightly arranged in the front-to-back direction, and the airbag strips are provided with bladder assemblies arranged in a straight line, and the adjacent bladder assemblies are connected by air passages, so that the air pressure of each bladder assembly on the airbag strip can be adjusted synchronously, and the adjacent airbag strips can achieve synchronous air pressure adjustment when they are connected to each other. The existing air passages are formed by connecting the pipe openings extending outward from the bladder assembly, and the pipe openings are formed during the assembly process of the bladder assembly, and the corresponding pipe openings of adjacent bladder assemblies are sealed and fixed by direct welding or by setting a connecting pipe. This not only affects the production efficiency due to the troublesome processing, but also easily causes damage and leakage due to the large number of welding areas, affecting the user experience. Summary of the invention

[0003] In order to address the deficiencies in the prior art, the present invention provides an airbag cushion and a mattress using the same. The air pipe passes through each bladder assembly in sequence to form an airbag strip. The air pipe is connected to each bladder assembly through a vent hole to form an air path. This simplifies processing operations and improves production efficiency. The entire air pipe is used to ensure sealing along the way, reduce the risk of air leakage, and improve the user experience.

[0004] The present invention is realized in the following manner: an airbag cushion, comprising airbag strips tightly arranged in the front-to-back direction, the airbag strips comprising linearly arranged bladder components and air pipes connecting the bladder components in series, the sections of the bladder components in each bladder component are provided with vents, so that the inner cavities of the bladder components are connected through the air pipes. The air pipes sequentially pass through the bladder components to form a linear airbag strip, the sections of the bladder components in each bladder component are provided with vents, so that the bladder components in the airbag strip are connected through the air pipes, the bladder components are connected in series to form an air path that does not require welding and assembly, which not only simplifies processing operations and improves production efficiency, but also uses a whole air pipe to ensure that the bladder components in the section between adjacent bladder components have good sealing, reduce the risk of air leakage, and improve the user experience.

[0005] Preferably, the bladder assembly includes an upper cover portion and a lower cover portion, the upper cover portion and the lower cover portion vertically clamp the trachea and enclose an inner cavity isolated from the outside world, and the inner cavity is connected to the outside world through corresponding vents, so that the bladder assembly can be vertically extended and adjusted in support. The upper cover portion and the lower cover portion are independently processed and assembled to form the bladder assembly, and the upper cover portion and the lower cover portion are stacked to clamp the trachea and are welded and fixed, which not only ensures that the upper cover portion and the lower cover portion can enclose a sealed inner cavity, but also ensures that the inner cavity is connected to the trachea through the vents, so that the inner cavities connected in series on the trachea are connected to each other, which is convenient for synchronous adjustment of air pressure.

[0006] Preferably, the upper cover part and the lower cover part are symmetrical structures, and the upper cover part and the lower cover part are both provided with upper grooves and lower grooves facing each other. The upper cover part and the lower cover part are vertically aligned and stacked and welded and sealed, so that the upper grooves and the lower grooves enclose the inner cavity. The upper cover part and the lower cover part are symmetrically arranged and have the same structure, which is convenient for mass production and does not need to be distinguished during assembly, thereby preventing assembly errors and effectively improving assembly efficiency. After installation, the notches of the upper groove and the lower groove are aligned and connected 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, and the upper notches and lower notches are aligned and overlapped and tightly wrap the trachea, so that the trachea, the upper notches and the lower notches are welded and sealed.

[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, 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 can be 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 hole is opened in the middle of the trachea located in the inner cavity section, and the vent hole 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 groove and the lower groove respectively, to ensure that the air pressure in the upper groove and the lower groove can be accurately adjusted.

[0012] Preferably, the side of the bladder assembly is provided with a conflicting portion extending along the direction in which the trachea is set, and adjacent bladder assemblies are positioned by the corresponding conflicting portions, so that the relative positions between adjacent bladder assemblies are fixed. The conflicting portion and the bladder assembly are integrally formed, which is convenient for processing, ensures that the structure and size of the conflicting portion are uniform, and improves the positioning accuracy. Adjacent bladder assemblies are positioned by the conflicting portions, ensuring that the distance between adjacent bladder assemblies is constant, and is convenient and quick to assemble.

[0013] Preferably, the end of the trachea is exposed at the end of the airbag strip and forms an air port connected to the outside world. The trachea is connected to the outside world through the air port, which is convenient for adjacent airbag strips to communicate through the air port to achieve synchronous air pressure regulation, and also convenient for the airbag strip to connect to the external air source through the air port to achieve precise air pressure regulation in each bag assembly.

[0014] A mattress using the airbag cushion comprises a cushion body, wherein the cushion body comprises an airbag cushion and a limit block for clamping and wrapping the airbag cushion. The limit block plays a role in clamping, positioning and protecting the airbag cushion, ensuring that the airbag cushion is adjusted in softness and hardness by inflating and deflating air at a preset position, thereby improving the comfort of the cushion body.

[0015] The beneficial effects of the present invention are as follows: the air pipe passes through each bag component in sequence to form a straight airbag strip, and the air pipe is provided with air holes on the sections inside each bag component, so that the bag components in the airbag strip are connected through the air pipe. The air pipe connects the bag components in series to form an air path that does not require welding and assembly, which simplifies the processing operation and improves production efficiency, and also uses a whole air pipe to ensure that the air pipe has good sealing in the section between adjacent bag components, reduces the risk of air leakage, and improves the user experience.

[0023] The essential features of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1:

[0025] This embodiment provides an airbag cushion.

[0026] like Figure 1 and 2 An airbag cushion shown includes an airbag strip 1 closely arranged in the front-to-back direction, the airbag strip 1 includes a linearly arranged bladder assembly 2 and an air tube 3 connecting the bladder assemblies 2 in series, and the air tube 3 is provided with a vent hole 4 on the section located in each bladder assembly 2, so that the inner cavity of each bladder assembly 2 is connected through the air tube 3. The air tube 3 sequentially passes through each bladder assembly 2 to form a linear airbag strip 1, and the air tube 3 is provided with a vent hole 4 on the section located in each bladder assembly 2, so that each bladder assembly 2 in the airbag strip 1 is connected through the air tube 3. The air tube 3 connects the bladder assemblies 2 in series and forms an air path channel that does not require welding and assembly, which not only simplifies the processing operation and improves the production efficiency, but also uses a whole air tube 3 to ensure that the air tube 3 is located between adjacent bladder assemblies 2. The section has good sealing, reduces the risk of air leakage, and improves the user experience.

[0027] In this embodiment, the capsule assembly 2 includes an upper cover portion 5 and a lower cover portion 6 (eg, Figure 3 As shown in the figure, the upper cover part 5 and the lower cover part 6 vertically clamp the trachea 3 and enclose an inner cavity isolated from the outside world, and the inner cavity is connected to the outside world through the corresponding vents 4, so that the bladder assembly 2 can be vertically expanded and contracted and the support can be adjusted. When processing the airbag strip 1, first, cut the trachea 3 that matches the length of the airbag strip 1, and open the vents 4 on the trachea 3; then, vertically stack the upper cover part 5 and the lower cover part 6 and clamp the trachea 3, so that the corresponding vents 4 on the trachea 3 are wrapped in the inner cavity enclosed by the upper cover part 5 and the lower cover part 6; then, weld the overlapping area between the upper cover part 5, the lower cover part 6 and the trachea 3 to form a sealed welding area; finally, arrange and install the bladder assembly 2 in sequence along the trachea 3, so that the trachea 3 is connected to the inner cavity of each bladder assembly 2 through the vents 4.

[0028] After the installation is completed, the air port 12 at the end of the trachea 3 is exposed at the end of the airbag strip 1, and each vent hole 4 on the trachea 3 is wrapped in the inner cavity of the corresponding bag assembly 2, so that each bag assembly 2 in the airbag strip 1 is connected with the trachea 3 through the vent hole 4, and then each bag assembly 2 on the airbag strip 1 is connected with the external trachea 3 through the trachea 3, ensuring that the air pressure of each bag assembly 2 in the airbag strip 1 can be adjusted synchronously.

[0029] In this embodiment, the end of the trachea 3 is exposed at the end of the airbag strip 1 and forms an air port 12 that communicates with the outside. The airbag strip 1 is connected to the 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. When in use, the air ports 12 of adjacent airbag strips 1 can be connected through pipelines, so that the air pressure in adjacent airbag strips 1 can be synchronously adjusted, so that the softness and hardness of the local area or the whole of the airbag cushion 13 that are interconnected can be synchronously adjusted. One end of the trachea 3 is located at one end of the airbag strip 1 and forms 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 are symmetrical structures, so that the upper cover part 5 and the lower cover part 6 have the same structure, which is convenient for large-scale production and does not need to distinguish the difference between the parts during assembly, which is convenient for quick assembly. In addition, the upper groove 7 and the lower groove 8 have differentiated depths, which can adjust the insertion position of the trachea 3 on the bladder assembly 2, for example, the trachea 3 is set at the bottom of the bladder assembly 2, and the trachea 3 is ensured not to be squeezed and blocked under the premise of ensuring the lifting range of the top of the bladder assembly 2, and can also be assembled to form various types of bladder assemblies 2 that meet the use requirements, effectively improving the scope of application of the trachea 3 series structure, which should be regarded as the specific implementation of this embodiment.

[0031] In this embodiment, the upper cover part 5 and the lower cover part 6 are both provided with an upper groove 7 and a lower groove 8 which are opened opposite to each other. The upper cover part 5 and the lower cover part 6 are vertically aligned and stacked and welded and sealed so that the upper groove 7 and the lower groove 8 enclose the inner cavity. The welding method is ultrasonic welding or high-frequency welding to ensure that the welding point has good sealing performance.

[0032] In this embodiment, upper notches 9 are provided on both sides of the notch periphery of the upper groove 7, and lower notches 10 are provided on both sides of the notch periphery of the lower groove 8. The upper notches 9 and the lower notches 10 are aligned and overlapped and tightly wrap the trachea 3, so that the trachea 3, the upper notches 9 and the lower notches 10 are welded and sealed. The upper notches 9 are two and one, and the axis of the upper cover part 5 is centrally symmetrically arranged. The cross-sectional profile of the upper notches 9 is arc-shaped and corresponds to the outer diameter of the trachea 3, ensuring that the outer wall of the trachea 3 can match and fit with the inner wall of the upper notches 9, which is convenient for welding and sealing, and 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 airflow rate. The lower notches 10 have the same structure as the upper notches 9, and can also play a role in sealing and avoiding squeezing the trachea 3.

[0033] In this embodiment, the notch peripheries of the upper groove 7 and the lower groove 8 are both planes, so that the bottom surface of the upper cover portion 5 and the top surface of the lower cover portion 6 fit closely. The cross-sectional profiles of the upper notch 9 and the lower notch 10 are semicircular, so that when the air pipe 3 is clamped in the upper notch 9 and the lower notch 10, the notch peripheries of the upper groove 7 and the lower groove 8 can match and fit, thereby facilitating welding and sealing.

[0034] In this embodiment, the vent hole 4 is opened in the middle of the trachea 3 located in the inner cavity section, and there are two vent holes 4, which are opened respectively toward the upper groove 7 and the lower groove 8. The vent hole 4 is arranged in the middle of the inner cavity, so as to ensure that the vent hole 4 can deliver airflow to each area of ​​the inner cavity, thereby ensuring that the air pressure of each area of ​​the inner cavity can be synchronously adjusted, and preventing the balloon assembly 2 from tilting horizontally when expanding and contracting due to the asynchronous inflation and deflation of 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 setting direction of the trachea 3, and adjacent bladder assemblies 2 are positioned by contacting with the corresponding contact portions 11, so that the relative positions between 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 are extended to both sides to form the contact portion 11, and the contact portion 11 extends along the setting direction of the trachea 3, which can increase the axial length of the upper notch 9 and the lower notch 10, thereby increasing the sealing reliability by increasing the width of the welding area, and can 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 bladder 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, and the cushion body includes an airbag cushion 13 and a stopper 14 for clamping and wrapping the airbag cushion 13. The stopper 14 clamps, positions and protects the airbag cushion 13, ensuring that the airbag cushion 13 is adjusted in softness and hardness by inflating and deflating air at a preset position, thereby improving the comfort of the cushion body.

[0040] In this embodiment, the limiting 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. During installation, the limiting 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), it ensures that the bladder assembly 2 can achieve vertical expansion and contraction under the guidance of the perforations, and then adjusts the hardness by adjusting the air pressure to provide comfortable support for the user.
