Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to an airbag cushion and mattress. Background Technology

[0002] Existing mattresses incorporate airbags for regulating air pressure. These airbags consist of several parallel airbag strips, each with linearly arranged unit airbags in a matrix pattern. Unit airbags on the same strip are interconnected. Each strip has an air nozzle at its end, connected to a control box via an air tube. This allows the control box to synchronously adjust the air pressure of each unit airbag on the strip, thus enabling adjustable mattress firmness to meet the diverse needs of different users. Because the airbag strips are positioned along the width of the mattress, the side edges and center of the same section are formed by the ends and center of the same airbag strip. This results in a uniform firmness between the edges and center. When the mattress is adjusted to a softer setting, the edges also soften, causing excessive sagging when the user sits on them. This fails to provide proper shaping and stable support for the user sitting on the edge, leading to slippage and a negative user experience.

[0003] In addition, because the user's surface is uneven, the unit capsules with the same softness and hardness on the capsule strip cannot match and fit the user's surface, affecting sleep comfort. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an airbag cushion and mattress with independently adjustable air pressure. Independent unit airbags are set on the airbag strip, and each unit airbag is connected to the air inlet pipe and the air outlet pipe through a corresponding air nozzle, so that the air pressure in each unit airbag can be adjusted independently, effectively improving the user experience.

[0005] This invention achieves its purpose through the following method: an airbag cushion with independently adjustable air pressure, comprising a cushion body and an air pressure regulating component. The cushion body includes several rows of parallel airbag strips, each strip having several equidistant and isolated unit airbags. The air pressure regulating component includes air pipes disposed between adjacent airbag strips, each air pipe including alternately arranged inlet and outlet pipes. Each unit airbag is connected to its corresponding inlet and outlet pipes via air nozzles on both sides, allowing the air pressure within each unit airbag to be independently adjusted. By setting independent unit airbags on the airbag strips, and laying inlet and outlet pipes on both sides of the airbag strips, with each unit airbag connected to its corresponding inlet and outlet pipes via air nozzles, the air pressure within each unit airbag can be independently adjusted to meet the user's needs in different scenarios and improve the user experience.

[0006] Preferably, the air tube is connected to each air nozzle along the route via a valve body, allowing for switching between connection and disconnection between each air nozzle and its corresponding air tube. The air tube is also connected to the corresponding air nozzle of each unit bladder along the route via a valve body, enabling the air tube and unit bladder to switch between a connected state with the valve body open and a disconnected state with the valve body closed, thereby allowing for corresponding inflation or deflation operations on each unit bladder.

[0007] Preferably, the air pipe is provided with branch pipes corresponding to the air nozzles along the route, and the valve body is connected between the branch pipes and the corresponding air nozzles. The branch pipes are used to connect the air pipe and the valve body, which not only ensures that the valve body can communicate with the air pipe, but also effectively reduces the air resistance in the air pipe cavity, ensuring smooth airflow in the air pipe.

[0008] Preferably, the valve body is a four-way valve connected in series with the trachea. The two valve ports of the four-way valve are respectively connected to the corresponding air nozzles, so that the corresponding air nozzles of adjacent bladders can share the four-way valve. The four-way valve is connected in series with the trachea through two valve ports, and the other two valve ports are respectively connected to the corresponding air nozzles of the two side unit bladders. The connection and disconnection status between the trachea and the two side unit bladders is controlled by the four-way valve, which effectively simplifies the structure and facilitates integrated control.

[0009] Preferably, adjacent bladder strips share an air inlet or exhaust pipe located between them. Each unit bladder on the bladder strip is inflated and deflated by air inlet and exhaust pipes located on both sides of it, so that the air pressure inside each unit bladder can be adjusted independently. The air inlet and exhaust pipes are alternately arranged in the gaps between adjacent bladder strips to ensure that there is a small distance between the bladder strip and the air inlet pipe, as well as between the bladder strip and the exhaust pipe. This ensures that air inlet and exhaust pipes are provided near each unit bladder, which facilitates pipeline laying and allows for independent control and adjustment of the air pressure inside each unit bladder.

[0010] Preferably, the airbag cushion has an intake manifold and an exhaust manifold arranged along its length on both sides. Each intake manifold is connected to the intake manifold via a corresponding end, and each exhaust manifold is connected to the exhaust manifold via a corresponding end. The intake manifold provides high-pressure air with balanced pressure to each intake manifold, ensuring that each unit airbag receives the same high-pressure air. The exhaust manifold receives airflow from each exhaust manifold, thereby enabling independent pressure regulation within each unit airbag. This effectively simplifies the pipeline structure and facilitates assembly and control.

[0011] Preferably, the lengths of the trachea and the bag strip are matched so that the trachea can be connected to each unit bag of the bag strip. This not only effectively shortens the distance between the trachea and the unit bag, facilitating connection, but also ensures that the distance between the trachea and each unit bag on the bag strip is the same, effectively reducing the difference in wind resistance caused by the difference in the trachea laying distance.

[0012] Preferably, the air pressure regulating assembly includes a control box and a wiring harness. The wiring harness is positioned below the bladder strip, with one end connected to the control box via a main guide wire and its side edges connected to valve bodies along the path via branch wires, allowing the valve bodies to be switched on and off. The control box transmits operating commands to each valve body via the wiring harness, ensuring that the air pressure inside each unit bladder can be independently and precisely adjusted. The wiring harness receives signals and power from the main guide wire and transmits them to each valve body via the branch wires, ensuring that the operating status of each valve body can be precisely controlled. Positioned below the bladder strip, the wiring harness is both pressed and positioned by the bladder strip and also positions the branch wires, ensuring that the branch wires can be connected to their corresponding valve bodies. Furthermore, by reducing the length of the branch wires, the wiring is kept neat and tidy, preventing tangling.

[0013] Preferably, the bladder strip includes a flat lower cover and an upper cover with a bladder groove. The upper and lower covers are stacked and bonded together so that the bladder groove is sealed and enclosed by the lower cover to form the bladder strip. The upper and lower covers are processed independently and then stacked and bonded together to form the bladder strip, which not only facilitates processing but also reduces the risk of air leakage by reducing the area of ​​the bonding region.

[0014] Preferably, the unit capsule has a capsule cavity, and the bottom sides of the capsule cavity extend outward to form an extended cavity. The air nozzle vertically passes through the bottom wall of the extended cavity and is exposed. The air nozzle includes an air inlet nozzle connected to the air inlet pipe and an air outlet nozzle connected to the air outlet pipe. The extended cavity is formed by extending outward from the bottom of the capsule cavity. One end of the extended cavity is connected to the capsule cavity, and the other end is connected to the air nozzle, ensuring that the air nozzle is vertically misaligned with the capsule body to prevent the air nozzle from being blocked or damaged by vertical compression from the capsule body.

[0015] A mattress includes an air-cushioned mattress. The air-cushioned mattress achieves a differentiated user experience by independently adjusting the air pressure inside each unit, resulting in different firmness in different areas of the mattress. This not only meets the needs of use in different scenarios but also ensures a close fit between the top surface of the mattress and the user's surface, thus improving support and comfort.

[0016] The beneficial effects of this utility model are as follows: independent unit bladders are set on the bladder strip, and air inlet pipes and exhaust pipes are laid on both sides of the bladder strip. Each unit bladder is connected to the air inlet pipe and exhaust pipe through a corresponding air nozzle, so that the air pressure in each unit bladder can be adjusted independently to meet the user's needs in different scenarios and improve the user experience.

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] This embodiment provides an airbag cushion.

[0028] like Figure 1 The illustrated airbag cushion with independently adjustable air pressure includes a cushion body and an air pressure regulating component. The cushion body includes several rows of parallel airbag strips 1, each strip 1 having several equidistant and isolated unit airbags 2. The air pressure regulating component includes air tubes disposed between adjacent airbag strips 1, each air tube including alternately arranged inlet pipes 3 and outlet pipes 4. Each unit airbag 2 is connected to its corresponding inlet pipe 3 and outlet pipe 4 via air nozzles on both sides, allowing the air pressure within each unit airbag 2 to be independently adjusted. By setting independent unit airbags 2 on the airbag strips 1, and laying inlet pipes 3 and outlet pipes 4 on both sides of the airbag strips 1, and connecting each unit airbag 2 to its corresponding inlet pipe 3 and outlet pipe 4 via air nozzles, the air pressure within each unit airbag 2 can be independently adjusted to meet the user's needs in different scenarios and improve the user experience.

[0029] In actual operation, the airbag cushion comprises several rows of parallel airbag strips 1, each airbag strip 1 having an equal number of equally spaced unit airbags 2, resulting in a matrix arrangement of the unit airbags 2. There are gaps between adjacent airbag strips 1, and each gap contains an air tube that matches the adjacent airbag strip 1. These air tubes alternately form an inlet pipe 3 and an outlet pipe 4 (e.g., ...). Figure 2 (As shown). Specifically, all air inlet pipes 3 are connected to the control box 15 to receive high-pressure air from the control box 15. The air inlet pipes 3 are connected to the air inlets 10 of each unit bladder 2 on both sides of the path, inflating each unit bladder 2. All exhaust pipes 4 are connected to the external space to discharge air from the bladder. The exhaust pipes 4 are connected to the exhaust nozzles 11 of each unit bladder 2 on both sides of the path, venting each unit bladder 2. By precisely controlling the inflation and deflation operations, the air pressure inside each unit bladder 2 can be independently and precisely adjusted, thereby allowing the firmness of each unit bladder 2 to be independently adjusted to meet the differentiated usage needs in different application scenarios, including but not limited to the following scenarios:

[0030] Scenario 1: When the user sits on the edge of the mattress, the firmness is increased by increasing the air pressure inside the unit 2 at the end of the bladder bar 1. This not only provides effective support for the user, but also shapes the edge of the mattress, preventing it from collapsing.

[0031] Scenario 2: When the user lies on the top center of the mattress, they can adjust the air pressure inside the middle unit 2 of the pleats 1 to obtain the appropriate firmness, thereby improving lying comfort.

[0032] Scenario 3: When the user lies on the top center of the mattress, the firmness of the corresponding unit 2 is set according to the unevenness of the user's surface, so that the top surface of the airbag can fit closely with the user's surface, thereby increasing the contact area and improving lying comfort.

[0033] In actual operation, each unit bladder 2 has an air inlet 10 and an exhaust nozzle 11 on its bottom sides, which are connected to the air inlet pipe 3 and the exhaust pipe 4, respectively. The air inlet 10 and the exhaust nozzle 11 are connected and disconnected from the air inlet pipe 3 and the exhaust pipe 4 through the corresponding valve body 5. When it is necessary to increase the air pressure of the unit bladder 2, the high-pressure air from the air inlet pipe 3 is received through the air inlet 10. When it is necessary to decrease the air pressure of the unit bladder 2, the air inside the unit bladder 2 is exhausted through the exhaust nozzle 11.

[0034] In actual operation, the air tube is connected to each air nozzle along the route via a valve body 5, allowing for switching between each air nozzle and its corresponding air tube. Specifically, the air tube is equipped with branch pipes 6 that correspond one-to-one with each air nozzle along the route, and the valve body 5 is connected between the branch pipe 6 and the corresponding air nozzle. The valve body 5 is configured to correspond one-to-one with each air nozzle to control the connection / disconnection state between the air nozzle and the air tube.

[0035] In actual operation, adjacent air strips 1 share an air inlet pipe 3 or an air outlet pipe 4 located between them. Each unit air bladder 2 on the air strip 1 is inflated and deflated through the air inlet pipe 3 and the air outlet pipe 4 located on both sides, so that the air pressure inside each unit air bladder 2 can be adjusted independently. The air inlet pipe 3 and the air outlet pipe 4 are arranged alternately to ensure that each air strip 1 has an air inlet pipe 3 and an air outlet pipe 4 on both sides, ensuring that each unit air bladder 2 on the air strip 1 can be inflated and deflated. The length of the air pipe matches that of the air strip 1 so that the air pipe can connect to each unit air bladder 2 of the air strip 1, ensuring that the air pipe can extend to each unit air bladder 2 of adjacent air strips, facilitating the connection of the air pipe to the air nozzle of the corresponding unit air bladder 2 through the valve body 5.

[0036] In actual operation, the airbag cushion is provided with an air intake manifold 13 and an exhaust manifold 14 arranged along its length on both sides. Each air intake manifold 3 is connected to the air intake manifold 13 through its corresponding end, and each exhaust manifold 4 is connected to the exhaust manifold 14 through its corresponding end. The air intake manifold 13 receives high-pressure air from the control box 15 and supplies air to the unit bladders 2 along the route through each air intake manifold 3, ensuring that each unit bladder 2 receives high-pressure air with the same pressure. The exhaust manifold 14 receives the airflow from each exhaust manifold 4 and guides it to be discharged outside the airbag cushion, thereby achieving independent pressure regulation within each unit bladder 2, effectively simplifying the pipeline structure and facilitating assembly and control. The ends of the air intake manifold 3 are vertically connected to the air intake manifold 13, and the ends of the exhaust manifold 4 are vertically connected to the exhaust manifold 14, effectively avoiding the airbag strip 1 and reducing the space occupied by the pipeline.

[0037] In actual operation, the air pressure regulating assembly includes a control box 15 and a wiring harness 7. The wiring harness 7 is positioned below the bladder strip 1. The end of the wiring harness 7 is connected to the control box 15 via a main guide wire 9, and its side edge is connected to the valve body 5 along its path via branch guide wires 8, allowing the valve body 5 to be opened and closed. The wiring harness 7 is positioned below the bladder strip 1 to press and position it, preventing it from shifting. The wiring harness 7 is parallel to the air tube, and the branch guide wires 8 are connected side-by-side to form the main guide wire 9 (e.g., ...). Figure 4 As shown), the section of the main guide line 9 located below the airbag strip 1 forms the wiring harness 7, and the section of the main guide line 9 located outside the airbag cushion is connected to the control box 15 (as shown). Figure 3 As shown), the branch wire 8 extends outward from the side edge of the wire harness 7 and connects to the corresponding valve body 5. It is used to transmit power and signals to the valve body 5, ensuring that the valve body 5 can be precisely controlled by the control box 15 and realize independent and precise adjustment of the air pressure in each unit bladder 2.

[0038] In actual operation, the bladder strip 1 includes a flat lower cover and an upper cover with a bladder groove. The upper and lower covers are stacked and bonded together so that the bladder groove is sealed and enclosed by the lower cover to form the bladder strip 1. The periphery of the bottom surface of the upper part and the periphery of the top surface of the lower part are stacked and bonded together to form the bladder body, effectively improving processing efficiency and reducing the risk of air leakage by reducing the area of ​​the bonding region. The bottom sides of the bladder cavity inside the unit bladder 2 extend outward to form an extended cavity 12 (e.g., Figure 6 As shown), the air nozzle vertically penetrates the bottom wall of the extended cavity 12 and is exposed. The air nozzle includes an air inlet 10 connected to the air inlet pipe 3 and an exhaust nozzle 11 connected to the exhaust pipe 4 (as shown). Figure 5 (As shown). The extended cavity 12 extends outward from the bottom of the bladder cavity. One end of the extended cavity 12 is connected to the bladder cavity, and the other end is connected to the air nozzle, ensuring that the air nozzle is vertically misaligned with the bladder body to prevent the air nozzle from being blocked or damaged by vertical compression from the bladder body.

[0039] Understandably, the valve body 5 is a four-way valve connected in series on the air tube. The two valve ports on both sides of the four-way valve are respectively connected to the corresponding air nozzles. The corresponding air nozzles of adjacent bladder strips 1 share a four-way valve, which effectively reduces the number of valve bodies 5 and facilitates integrated control. This should also be regarded as a specific implementation of this embodiment.

[0040] Example 2:

[0041] Compared to Embodiment 1, this embodiment provides a mattress.

[0042] like Figure 7 The mattress shown includes an air cushion 16. The air cushion 16 achieves a differentiated user experience by independently adjusting the air pressure inside each unit 2, resulting in different firmness in different areas of the mattress. This not only meets the needs of use in different scenarios but also ensures a close fit between the top surface of the mattress and the user's surface, enhancing support and comfort.

[0043] In this embodiment, the mattress may also be equipped with optional structures such as side skirts, comfort layers, support layers, bottom pads, and outer covers, all of which should be considered as specific implementations of this embodiment.

[0044] The other structures and effects of the airbag cushion described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
