Description

Airbag cushion and mattress using the same Technical Field

[0001] The present invention relates to the field of bedding, in particular to an airbag cushion and a mattress using the same. Background Art

[0002] Existing mattresses consist of an outer cover and a cushion body. The outer cover includes an upper quilted layer and a lower quilted layer that completely enclose the cushion body. The cushion body comprises a comfort layer, an airbag cushion, an airbag securing layer, and a support layer. The support layer provides overall support for the airbag cushion, while the comfort layer deforms to conform to the user's surface, enhancing sleeping comfort. The airbag cushion contains densely arranged massage airbags, which adjust their vertical height by inflating and deflating, providing a pressing force to the user. The existing massage airbag includes multiple vertically stacked unit bags. When the massage airbag switches to the contracted state by deflating, each unit bag will not be able to fit accurately and tightly due to the non-planar wall surface, and the top wall and bottom wall of each unit bag are vertically stacked together, resulting in a larger thickness of the massage airbag when in the contracted state, causing the user to have a foreign body sensation and affect the sleeping experience. In addition, the outer edge contours of each unit bag are the same, and the massage airbag will be subjected to more horizontal forces due to the larger volume of the top, making the massage airbag prone to horizontal displacement during vertical deformation, which in turn causes the massage airbag to be unable to press accurately due to the inability to deform along the preset path, affecting the user experience. Summary of the Invention

[0003] In order to address the deficiencies of the prior art, the present invention provides an airbag cushion and a mattress using the same, improves the structure of the massage airbag, and provides a folded ring formed by repeated horizontal folding from the center to the outside on the periphery of the top wall, which not only ensures that the massage airbag can be vertically deformed and switch between an inflated state and a contracted state, exerting a pressing force on the user, but also can utilize the horizontally arranged folded ring to perform vertical stacking operations, effectively reducing the thickness of the massage airbag when in a contracted state, reducing the foreign body sensation, and can also utilize the structural strength of the folded ring itself to guide the deformation of the massage airbag, preventing the massage airbag from horizontally offsetting during vertical deformation.

[0004] The present invention is achieved in the following manner: an airbag cushion includes a massage airbag, the massage airbag includes a bottom wall and a top wall that can be vertically expanded and deformed, the middle part of the top wall bulges upward to form a convex point, and the periphery of the top wall is provided with a folded ring formed by repeated horizontal folding from the middle to the outside. The massage airbag is switched between an inflated state in which adjacent folded rings are vertically expanded and a contracted state in which adjacent folded rings are vertically stacked by inflation and deflation. The structure of the massage airbag is improved, and a folded ring is provided on the periphery of the top wall, which is formed by repeated horizontal folding from the center to the outside. The folded ring is expanded layer by layer from top to bottom, so that the outer edge of the upper folded ring can be vertically stacked on the inner edge of the lower folded ring. The massage airbag realizes vertical deformation switching between the inflated state and the contracted state by inflation and deflation, and uses the convex points to apply a pressing force to the user. The horizontally arranged folded ring can be used for vertical stacking operation, and the thickness of the massage airbag in the contracted state can be reduced by stacking the folded ring, thereby reducing the foreign body sensation caused to the user when the massage airbag switches to the contracted state. The folded ring's anti-deformation performance in the horizontal direction can also be used to guide the deformation of the massage airbag, thereby preventing the massage airbag from horizontally offsetting during vertical deformation.

[0005] Preferably, the folding ring includes a wide ring and a narrow ring alternately arranged radially along the top wall, and the vertical projection of the narrow ring completely falls within the adjacent wide ring. The radial width of the wide ring is greater than the radial width of the narrow ring, and the wide ring and the narrow ring are alternately arranged, which not only ensures that the adjacent wide rings are sealed and connected through the narrow ring, and ensures that the inner cavity of the massage airbag has good sealing performance, and facilitates air pressure adjustment, but also realizes the vertical deformation switching of the massage airbag by adjusting the angle between the adjacent narrow ring and the wide ring, and smoothly outputs the pressing force by reducing the deformation resistance, and can also realize the alternating arrangement of wide and narrow rings and increase them layer by layer by setting differentiated sizes, ensuring that the vertical projection of the top wall can completely cover the bottom wall. The overlapping area between adjacent wide and narrow rings can be expanded when the massage airbag switches to the inflated state, ensuring that the massage airbag can deform upward and apply a pressing force to the user.

[0006] Preferably, the radial width of the wide ring is A, the radial width of the narrow ring is B, A≥2B, adjacent narrow rings are respectively fixed to the inner edge and outer edge of the same wide ring, and A≥2B, so that the vertical projections of adjacent narrow rings do not overlap with each other. When the massage airbag switches to the contracted state, the thickness of each area does not exceed four layers, including adjacent wide rings, narrow rings arranged between adjacent wide rings, and the bottom wall. While ensuring that the vertical deformation height of the massage airbag remains unchanged, the thickness is reduced by reducing the number of stacked layers, thereby reducing the foreign body sensation to the user.

[0007] Preferably, when the massage airbag is switched to the contracted state, the narrow ring is vertically clamped by the adjacent wide ring, and the vertical projections of the narrow rings are staggered with each other to reduce the thickness of the massage airbag. The wide ring and the narrow ring are both annular flat plates. After the massage airbag is deflated, the adjacent wide ring and narrow ring fit tightly, which is conducive to the complete discharge of gas and effectively reduces the thickness of the massage airbag.

[0008] Preferably, when the massage airbag is inflated, the narrow and wide rings are tilted to elevate the raised points and generate a massaging force. The narrow and wide rings swing apart around their attached edges, expanding and raising the raised points, ensuring that the raised points exert a pressing force on the user.

[0009] Preferably, the inner edge of the narrow ring is connected to the inner edge of the wide ring below to form a hidden crease that guides the vertical deformation of the massage airbag. The hidden crease is arranged at the inner edge of the narrow ring, which not only guides the adjacent narrow rings and wide rings to be stacked along the hidden crease, but also improves the resistance to horizontal deformation and prevents the massage airbag from undergoing horizontal deformation.

[0010] Preferably, the outer edge of the narrow ring is connected to the outer edge of the wide ring above to form an exposed crease that guides the vertical deformation of the massage airbag. The exposed crease is arranged at the outer edge of the narrow ring, which not only guides the adjacent narrow rings and wide rings to be stacked along the exposed crease, but also improves the resistance to horizontal deformation and prevents the massage airbag from undergoing horizontal deformation.

[0011] Preferably, the diameter of the folded ring increases gradually from top to bottom, so that the massage airbag assumes a frustum-shaped configuration with a smaller top and a larger bottom when switched to the inflated state. This frustum-shaped configuration, when inflated, reduces both horizontal force and horizontal deflection of the top of the massage airbag by reducing the volume of the top of the massage airbag. Furthermore, the reduced surface area of ​​the massage airbag reduces the force applied to the user, thereby increasing the pressing force.

[0012] Preferably, the airbag cushion includes a base with an internal air conduit. The massage airbag is connected to the air conduit via a vent located on the top surface of the base. The air conduit is equipped with an air nozzle that communicates with an external controller. The base not only supports and positions the massage airbag, but also utilizes the air conduit within it to regulate the air pressure within the massage airbag. The air conduit is connected to the controller via the air nozzle, and the controller controls the air pressure within the massage airbag.

[0013] Preferably, the base includes an integrated bottom layer and an airway layer covering the bottom layer, the airway layer includes densely arranged unit sheets and long strips spanning between adjacent unit sheets, the unit sheets forming the bottom wall, the vents being provided on the unit sheets, the periphery of the airway layer being hot-melt bonded to the bottom layer so that the airway layer and the bottom layer enclose the airway duct. The airway layer and the bottom layer are independently processed and bonded to form the base, the periphery of the airway layer being bonded to the bottom layer so as to enclose the airway duct between the bottom surface of the airway layer and the top surface of the bottom layer, which is not only convenient for processing but also ensures that the laying of the airway duct meets the use requirements and ensures that each massage airbag can be connected to the airway duct provided in the base through the vent.

[0014] Preferably, the airbag cushion includes at least one zone, divided from front to back, comprising a shoulder support zone, a waist support zone, a hip support zone, and a leg support zone. The air pressure of the massage airbags in each zone is uniformly regulated, ensuring differentiated hardness and softness adjustment. The zone division also simplifies the airway piping structure, facilitating production and maintenance.

[0015] Preferably, the top wall and bottom wall are respectively provided with an upper magnetic part and a lower magnetic part that are vertically attracted. The massage airbag is inflated and accumulates a preload force for vertical expansion. When the preload force overcomes the attraction force between the upper magnetic part and the lower magnetic part, the protrusion bounces upward under the drive of the preload force, and the pressing force is increased by increasing the speed at which the protrusion moves upward. The massage airbag structure is improved by providing an upper magnetic part and a lower magnetic part that can generate an attraction force on the top wall and the bottom wall of the massage airbag. When the massage airbag is inflated, the massage airbag uses the attraction force to limit vertical deformation and accumulate preload force. The preload force increases as the air pressure in the massage airbag increases, so that the upper magnetic part can be separated from the lower magnetic part when the preload force is greater than the attraction force. The massage airbag drives the protrusion to bounce upward quickly through the top wall and increases the pressing force applied to the user, effectively improving the massage comfort. When the massage airbag switches from a contracted state to an inflated state through inflation, the top wall and the bottom wall will remain fixed in relative position due to the attraction force between the upper magnetic part and the lower magnetic part, so that a pre-tightening force will be generated between the top wall and the bottom wall to drive the two to separate vertically.

[0016] Preferably, the upper magnetic part is arranged in the middle of the top wall, and the lower magnetic part is arranged in the middle of the bottom wall. The bottom surface of the upper magnetic part and the top surface of the lower magnetic part are attracted to each other in opposite directions, so that the upper magnetic part and the lower magnetic part limit the upward movement of the top wall by mutual attraction and accumulate the pre-tightening force. The upper magnetic part and the lower magnetic part are vertically attracted to each other and ensure that the middle of the top wall and the middle of the bottom wall are tightly fitted. The periphery of the top wall has the same vertical deformation amplitude, ensuring that the protrusion can move up and down in the vertical direction under the drive of the pre-tightening force, so that the vertical pre-tightening force generated by the massage airbag can be effectively converted into a pressing force, thereby improving the comfort of massage. The bottom surface of the upper magnetic part and the top surface of the lower magnetic part are attracted to each other in opposite directions, ensuring that the direction of the attraction force is consistent with the direction of the pre-tightening force required to drive the protrusion, thereby improving the conversion efficiency between the pre-tightening force and the pressing force.

[0017] Preferably, the middle part of the top wall is formed into a convex cavity by bulging upward, the outer wall of the convex cavity forms the convex point, and the upper magnetic part is installed at the lower end of the convex cavity through the upper fixing part, so that the upper magnetic part and the convex point move synchronously. The upper magnetic part is located below the convex point, which can not only ensure that the attraction force and the pre-tightening force are set in the same direction, but also increase the weight of the middle part of the top wall by setting the upper magnetic part, and then increase the pressing force of the convex point by increasing the kinetic energy. The upper fixing part plays a role in positioning the upper magnetic part, ensuring that the top surface of the lower magnetic part and the bottom surface of the upper magnetic part can match and attract.

[0018] Preferably, the convex cavity is connected to a massage airbag via a lower port, which inflates the convex cavity and increases the hardness of the raised points. The convex cavity is connected to the inner cavity of the massage airbag and has the same air pressure. The convex cavity receives the high-pressure air from the massage airbag and increases the hardness of the raised points, effectively improving the transmission of pressure between the raised points and the user, thereby enhancing massage comfort.

[0019] Preferably, the convex cavity is provided with a filler, and the upper fixing member blocks the lower end of the convex cavity and seals the filler. The filler increases the hardness of the convex point, effectively improving the transmission efficiency of the pressing force between the convex point and the user, thereby enhancing massage comfort. The upper fixing member not only secures the upper magnetic member but also blocks the lower end of the convex cavity, preventing the filler from escaping the cavity.

[0020] Preferably, the lower magnetic member is fixed to the middle of the bottom wall by a lower fixing member. The lower fixing member plays a role in positioning the lower magnetic member, ensuring that the top surface of the lower magnetic member and the bottom surface of the upper magnetic member can match and engage.

[0021] Preferably, when the massage airbag is deflated, the upper magnetic member descends and engages with the lower magnetic member, thereby guiding the massage airbag to reset and switch from an inflated state in which adjacent folds are vertically expanded to a contracted state in which adjacent folds are vertically stacked. The upper magnetic member can descend when the massage airbag is deflated and, through vertical engagement with the lower magnetic member, generate an attractive force. This not only drives the top wall toward the bottom wall and facilitates rapid expulsion of air from the massage airbag, but also ensures that the middle of the top wall always remains vertically aligned with the middle of the bottom wall, guiding the massage airbag to precisely reset to its contracted state, ensuring that the protrusion rises and falls vertically along a preset path, and reducing the thickness of the massage airbag through precise reset, thereby minimizing the foreign body sensation for the user. In addition, a folding ring is provided on the periphery of the top wall, which is formed by repeated horizontal folding from the middle to the outside. The folding ring is expanded layer by layer from top to bottom, so that the outer edge of the upper folding ring can be vertically stacked on the inner edge of the lower folding ring. The massage airbag realizes vertical deformation switching between the inflated state and the contracted state by inflation and deflation, and uses the convex points to apply a pressing force to the user. The horizontally arranged folding ring can be used for vertical stacking operation, and the thickness of the massage airbag in the contracted state can be reduced by stacking the folding ring, thereby reducing the foreign body sensation caused to the user when the massage airbag switches to the contracted state. The deformation resistance of the folding ring in the horizontal direction can also be used to guide the deformation of the massage airbag, thereby preventing the massage airbag from horizontally offsetting during vertical deformation.

[0022] A mattress using the airbag cushion comprises an outer cover and a cushion body. The outer cover includes an upper quilted layer and a lower quilted layer that completely enclose the cushion body. The cushion body comprises, arranged in order from top to bottom, a comfort layer, an airbag cushion, an airbag securing layer, and a support layer. The cushion body is provided with a peripheral edge, and a controller for controlling the inflation and deflation of the airbag cushion is located within the rear end of the peripheral edge. The controller is located within the rear end of the peripheral edge, facilitating installation and maintenance, shortening the distance between the cushion and the airbag to facilitate piping installation, and reducing the impact of controller operating noise on the user, thereby improving the user experience.

[0023] The beneficial effects of the present invention are as follows: the structure of the massage airbag is improved, and a folding ring formed by repeated horizontal folding from the middle to the outside is provided on the periphery of the top wall. The folding ring is expanded layer by layer from top to bottom, so that the outer edge of the upper folding ring can be vertically overlapped on the inner edge of the lower folding ring. The massage airbag is vertically deformed and switched between the inflated state and the deflated state by inflation and deflation, and the convex point is used to apply a pressing force to the user. The horizontally arranged folding ring can be used for vertical stacking operation, and the thickness of the massage airbag in the deflated state can be reduced by stacking the folding ring, thereby reducing the foreign body sensation caused to the user when the massage airbag is switched to the deflated state. The deformation resistance of the folding ring in the horizontal direction can also be used to guide the deformation of the massage airbag, thereby preventing the massage airbag from horizontally deflecting during vertical deformation.

[0024] The massage airbag structure has been improved. Upper and lower magnetic parts that can generate an attractive force are respectively provided on the top and bottom walls of the massage airbag. When the massage airbag is inflated, the massage airbag uses the attractive force to limit vertical deformation and accumulate preload. The preload increases with the increase in air pressure in the massage airbag. When the preload force is greater than the attractive force, the upper magnetic part can be separated from the lower magnetic part. The massage airbag drives the protrusion upward through the top wall and increases the pressing force applied to the user, effectively improving massage comfort.

[0025] The upper magnetic part can drop when the massage airbag is deflated and generate a suction force through vertical attraction with the lower magnetic part, which can not only drive the top wall closer to the bottom wall and assist the rapid discharge of air in the massage airbag, but also ensure that the middle of the top wall is always vertically aligned with the middle of the bottom wall, guiding the massage airbag to accurately reset to the contracted state, ensuring that the protrusion rises and falls vertically along the preset path, and reducing the thickness of the massage airbag through precise reset, thereby reducing the foreign body sensation to the user.

[0037] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0038] Example 1:

[0039] This embodiment provides an airbag cushion.

[0040] An airbag cushion as shown in Figures 1 and 2 includes a massage airbag 1, which includes a bottom wall 2 and a top wall 3 that can be vertically stretched and deformed. The middle part of the top wall 3 bulges upward to form a protrusion 4, and the periphery of the top wall 3 is provided with a folded ring formed by repeated horizontal folding from the middle to the outside. The massage airbag 1 is switched between an inflated state in which adjacent folded rings are vertically expanded and a contracted state in which adjacent folded rings are vertically stacked by inflation and deflation. The structure of the massage airbag 1 is improved, and a folded ring is provided on the periphery of the top wall 3, which is formed by repeated horizontal folding from the center to the outside. The folded ring is expanded layer by layer from top to bottom, so that the outer edge of the upper folded ring can be vertically stacked on the inner edge of the lower folded ring. The massage airbag 1 realizes vertical deformation switching between the inflated state and the contracted state by inflation and deflation, and uses the convex point 4 to apply a pressing force to the user. The horizontally arranged folded ring can be used for vertical stacking operation, and the thickness of the massage airbag 1 in the contracted state can be reduced by stacking the folded ring, thereby reducing the foreign body sensation caused to the user when the massage airbag 1 switches to the contracted state. The anti-deformation performance of the folded ring in the horizontal direction can also be used to guide the deformation of the massage airbag 1, thereby preventing the massage airbag 1 from horizontally offsetting during vertical deformation.

[0041] In this embodiment, the folding ring includes wide rings 5 ​​and narrow rings 6 alternately arranged radially along the top wall 3, with the vertical projections of the narrow rings 6 completely falling within adjacent wide rings 5. The wide rings 5 ​​and narrow rings 6 are alternately stacked from the inside out. The top wall 3 includes four groups of wide rings 5 ​​and narrow rings 6. The inner edge of the first wide ring 5 is sealed to the periphery of the protrusion 4, the outer edge of the first wide ring 5 is sealed to the outer edge of the first narrow ring 6, the inner edge of the first narrow ring 6 is sealed to the inner edge of the second wide ring 5, and so on. The outer edge of the fourth narrow ring 6 is sealed to the bottom wall 2, so that the bottom wall 2, the protrusion 4, and the four groups of wide rings 5 ​​and narrow rings 6 cooperate to form the massage airbag 1. During use, the massage airbag 1 is switched to the inflated state by inflation, and the convex point 4 will be lifted upward due to the vertical expansion and deformation of the massage airbag 1, thereby applying a pressing force to the user. During this process, the adjacent wide rings 5 ​​and narrow rings 6 will be unfolded with the connecting edge as the center and guide the massage airbag 1 to expand vertically; the massage airbag 1 is switched to the contracted state by deflating, and the convex point 4 will move downward due to the vertical contraction and deformation of the massage airbag 1, thereby canceling the pressing force on the user. During this process, the adjacent wide rings 5 ​​and narrow rings 6 will be vertically stacked with the connecting edge as the center (as shown in Figure 3), and the thickness of the massage airbag 1 is reduced by the mutual fit between the adjacent wide rings 5 ​​and narrow rings 6, thereby reducing the foreign body sensation caused to the user.

[0042] In this embodiment, the diameter of the folded ring increases layer by layer from top to bottom, so that the massage airbag 1 takes on a frustum-shaped shape with a smaller top and a larger bottom when switched to the inflated state. Specifically, the inner diameter of the first wide ring 5 is smaller than the inner diameter of the second wide ring 5, and the outer diameter of the first wide ring 5 is between the inner and outer diameters of the second wide ring 5. The stepwise increase in the diameter of each wide ring 5 ensures that the top wall 3 can completely cover the bottom wall 2 and enclose the massage airbag 1, and also ensures that the top wall 3 can achieve the effect of lifting and lowering the protrusion 4 through vertical deformation. In addition, the frustum-shaped massage airbag 1 has both inclined sidewalls that can convert horizontal outward forces into vertical forces, effectively improving the massage airbag 1's resistance to horizontal deformation, and a smaller top surface, which increases the pressing force by reducing the top surface area.

[0043] In this embodiment, when the massage airbag 1 switches to the contracted state, the narrow ring 6 is vertically clamped by the adjacent wide ring 5. The vertical projections of the narrow rings 6 are offset from each other to reduce the thickness of the massage airbag 1. Specifically, the radial width of the wide ring 5 is A, and the radial width of the narrow ring 6 is B, where A ≥ 2B. The smaller radial width of the narrow ring 6 not only effectively connects the wide rings 5 ​​of different diameters, but also provides the increased exposed area required for vertical deformation of the top wall 3 when the massage airbag 1 switches to the inflated state, ensuring that the top wall 3 can vertically expand and contract in a predetermined manner. The radial width of the wide ring 5 is at least twice that of the narrow ring 6. This ensures that the narrow rings 6 located at the inner and outer edges of the same wide ring 5 do not overlap when the massage airbag 1 switches to the contracted state. By preventing vertical overlap of adjacent narrow rings 6, the number of overlapping layers is reduced, thereby reducing the thickness of the massage airbag 1. Between adjacent wide rings 5, the outer edge of the wide ring 5 located above and the inner edge of the wide ring 5 located below are vertically overlapped, and the radial width of the vertical overlapping area matches the radial width of the narrow ring 6 between the two, ensuring that adjacent wide rings 5 ​​and narrow rings 6 can be stacked flatly.

[0044] In this embodiment, when the massage airbag 1 is inflated, the narrow ring 6 and wide ring 5 are tilted, causing the protrusion 4 to rise upward and generate a massaging force. The narrow ring 6 and wide ring 5 can be deployed around their connecting edge, and the vertical lift distance of the protrusion 4 can be increased by increasing the angle between them. Adjusting the height of the protrusion 4 can then adjust the pressure applied to the user.

[0045] In this embodiment, the inner edge of the narrow ring 6 connects to the inner edge of the lower wide ring 5, forming a hidden fold 7 that guides the vertical deformation of the massage airbag 1. The outer edge of the narrow ring 6 connects to the outer edge of the upper wide ring 5, forming an exposed fold 8 that guides the vertical deformation of the massage airbag 1. The exposed folds 8 and hidden folds 7 are arranged alternately from the inside to the outside along the top wall 3 in a Z-shaped undulating pattern. This not only ensures that the massage airbag 1 can switch between the inflated and deflated states in the vertical direction, but also improves the massage airbag 1's resistance to horizontal deformation, preventing the top of the massage airbag 1 from being unable to transmit the vertical pressure due to horizontal deviation.

[0046] In this embodiment, the airbag cushion includes a base with an internal air conduit. The massage airbags 1 communicate with the air conduit via vents 9 located on the top surface of the base. The air conduit is equipped with an air nozzle that communicates with an external controller 21. The airbag cushions share a common base, and the air conduit is disposed within the base. The air conduit is connected to the controller 21 and the corresponding massage airbag 1 via the air nozzle and vent 9, respectively. This allows the controller 21 to control the air pressure within the massage airbag 1 through the air conduit, thereby applying a compressive force to the user by driving the massage airbag 1 up and down.

[0047] In this embodiment, the base includes an integral bottom layer 11 and an airway layer 10 covering the bottom layer 11 (as shown in FIG4 ). The airway layer 10 includes densely arranged unit sheets 12 and long strips 13 spanning between adjacent unit sheets 12. The unit sheets 12 form the bottom wall 2. The vents 9 are provided on the unit sheets 12 (as shown in FIG5 ). The periphery of the airway layer 10 is hot-melt bonded to the bottom layer 11 so that the airway layer 10 and the bottom layer 11 enclose the airway duct. The bottom layer 11 and the airway layer 10 are both integral sheet structures. The airway layer 10 includes the unit sheets 12 and the long strips 13. The airway layer 10 is hot-melt bonded to the bottom layer 11 through the edges of the unit sheets 12 and the long strips 13 so that the airway layer 10 and the bottom layer 11 enclose the airway duct to form. The top surface of the unit piece 12 forms the bottom wall 2 , and a vent 9 is provided on the unit piece 12 so that the air pipeline is connected to the massage airbag 1 through the vent 9 .

[0048] In this embodiment, the airbag cushion includes at least one zone, divided from front to back, comprising a shoulder support zone, a waist support zone, a hip support zone, and a leg support zone. The massage airbags 1 are densely arranged, with adjacent rows of massage airbags 1 staggered, effectively increasing the density of the massage airbags 1. The airbag cushion is divided into multiple zones, each with independently adjustable firmness, providing differentiated pressure for different segments of the user's body, enhancing massage comfort. Furthermore, the massage airbags 1 can be arranged in a matrix, which should also be considered a specific embodiment of this embodiment.

[0049] In this embodiment, the central portion of the top wall 3 is raised upward to form a convex cavity 24, and the outer wall of the convex cavity 24 forms the protrusion 4. The convex cavity 24 is connected to the massage airbag 1 and can be inflated and deflated simultaneously. A filler can also be placed within the convex cavity 24. The upper fixing member 25 blocks the lower end of the convex cavity 24 and seals the filler. The filler increases the hardness of the protrusion 4, facilitating the transmission of the pressing force. It also reduces noise caused by material deformation by limiting the deformation of the protrusion 4, thereby improving the quietness performance. This should also be considered a specific implementation of this embodiment.

[0050] It can be understood that the number of groups of wide rings 5 ​​and narrow rings 6 included in the top wall 3 can be adjusted as needed, for example, set to two groups, three groups, five groups, etc., which should all be regarded as specific implementation methods of this embodiment.

[0051] Example 2:

[0052] Compared with the first embodiment, this embodiment provides another airbag cushion.

[0053] An airbag cushion as shown in Figures 6 and 7 is composed of a massage airbag 1, which includes a bottom wall 2 and a top wall 3 that can be vertically stretched and deformed. The middle part of the top wall 3 bulges upward to form a convex point 4. The top wall 3 and the bottom wall 2 are respectively provided with an upper magnetic part 22 and a lower magnetic part 23 that are vertically attracted. The massage airbag 1 is inflated and accumulates a pre-tightening force for vertical expansion. When the pre-tightening force overcomes the attraction force between the upper magnetic part 22 and the lower magnetic part 23, the convex point 4 bounces upward under the drive of the pre-tightening force, thereby increasing the pressing force by increasing the speed at which the convex point 4 moves upward. The structure of the massage airbag 1 is improved, and an upper magnetic component 22 and a lower magnetic component 23 that can generate an attractive force are respectively provided on the top wall 3 and the bottom wall 2 of the massage airbag 1. When the massage airbag 1 is inflated, the massage airbag 1 uses the attractive force to limit the vertical deformation and accumulate pre-tightening force. The pre-tightening force will increase as the air pressure in the massage airbag 1 increases, so that the upper magnetic component 22 can be separated from the lower magnetic component 23 when the pre-tightening force is greater than the attractive force. The massage airbag 1 drives the protrusion 4 to bounce upward quickly through the top wall 3 and increases the pressing force applied to the user, thereby effectively improving the massage comfort.

[0054] In this embodiment, the upper magnetic member 22 is positioned in the middle of the top wall 3, and the lower magnetic member 23 is positioned in the middle of the bottom wall 2 (as shown in FIG8 ). The bottom surface of the upper magnetic member 22 and the top surface of the lower magnetic member 23 are oppositely attracted to each other, so that the upper magnetic member 22 and the lower magnetic member 23 engage with each other to limit the upward movement of the top wall 3 and accumulate the preload force. When the massage airbag 1 is in the collapsed state (as shown in FIG9 ), the top wall 3 is in contact with the bottom wall 2, the bottom surface of the upper magnetic member 22 is vertically attracted to the top surface of the lower magnetic member 23, the folded ring is in a collapsed state, and the wide ring 5 and narrow ring 6 are in contact with each other. At this point, the massage airbag 1 reduces its thickness, eliminating the foreign body sensation to the user. When the massage airbag 1 is inflated, the folded ring is in an expanded state, and the wide ring 5 and narrow ring 6 expand around the connecting edge, allowing the massage airbag 1 to have vertical deformation space.

[0055] When the massage airbag 1 switches from a contracted state to an inflated state, the controller inflates the massage airbag 1, and the top wall 3 and the bottom wall 2 will remain fixed in relative position due to the attractive force between the upper magnetic part 22 and the lower magnetic part 23, so that a pre-tightening force will be generated between the top wall 3 and the bottom wall 2 to drive the two to separate vertically. The air pressure in the massage airbag 1 will increase with the increase of the amount of air filled, so that the pre-tightening force will also increase accordingly. When the pre-tightening force is greater than the attractive force, the upper magnetic part 22 will move upward under the drive of the top wall 3 and disengage from the lower magnetic part 23, and the protrusion 4 will also bounce upward at a faster speed with the top wall 3. The protrusion 4 generates a pressing force by hitting the user upward to create a massage acupressure effect.

[0056] When the massage airbag 1 switches from the inflated state to the deflated state, the controller extracts the gas in the massage airbag 1, and the top wall 3 descends and moves closer to the bottom wall 2 through the mutual attraction of the upper magnetic part 22 and the lower magnetic part 23, which not only guides the folding of the folding ring, but also ensures that the middle part of the top wall 3 is always vertically aligned with the middle part of the bottom wall 2 during the descending process, thereby ensuring that the folding ring is accurately reset from the expanded state to the collapsed state, preventing the folding ring from being unable to fold in the preset manner due to radial offset of the top wall 3, and effectively reducing the thickness of the massage airbag 1.

[0057] In this embodiment, the upper magnetic part 22 and the lower magnetic part 23 cooperate with each other, and can use the suction force between the two to assist the massage airbag 1 to accumulate pre-tightening force, and increase the rising speed of the protrusion 4 by increasing the pre-tightening force, thereby increasing the pressing force applied to the user, and ensuring the comfort of massage by enhancing the pressing sensation. The suction force between the two can also be used to guide the top wall 3 to move closer to the bottom wall 2, and the folding ring plays a role in guiding the folding. The massage airbag 1 controls the thickness by switching to a contracted state according to a preset folding method, thereby reducing the foreign body sensation caused by the massage airbag 1 to the user, improving lying comfort, and ensuring that the massage airbag 1 can accurately guide the protrusion 4 to rise and fall back along the vertical path, preventing the protrusion 4 from being horizontally offset and the pre-tightening force cannot be effectively converted into a pressing pre-tightening force.

[0058] In this embodiment, the upper magnetic element 22 is mounted at the lower end of the convex cavity 24, so that the upper magnetic element 22 and the protrusion 4 move synchronously. The top surface of the protrusion 4 is spherical with an upward bulge in the middle, which can not only effectively transmit the pressing force, but also adapt to the user's performance through its own deformation, thereby improving massage comfort.

[0059] In this embodiment, the upper magnetic member 22 is mounted at the lower end of the convex cavity 24 via an upper fixing member 25, and the lower magnetic member 23 is mounted in the middle of the bottom wall 2 via a lower fixing member 26. This not only positions the upper magnetic member 22 and the lower magnetic member 23, ensuring that they are vertically aligned, but also limits the posture of the upper magnetic member 22 and the lower magnetic member 23, ensuring that the bottom surface of the upper magnetic member 22 is always facing the top surface of the lower magnetic member 23, ensuring that an attractive force is generated between the bottom surface of the upper magnetic member 22 and the top surface of the lower magnetic member 23. The periphery of the upper fixing member 25 is adhered to the periphery of the lower end of the convex cavity 24, and the periphery of the lower fixing member 26 is adhered to the middle of the bottom wall 2.

[0060] In this embodiment, when the massage airbag 1 switches to the contracted state, the narrow ring 6 is vertically clamped by the adjacent wide ring 5. The vertical projections of the narrow rings 6 are offset from each other to reduce the thickness of the massage airbag 1. The radial width of the wide ring 5 is A, and the radial width of the narrow ring 6 is B, where A ≥ B. The smaller radial width of the narrow ring 6 not only effectively connects the wide rings 5 ​​of different diameters, but also provides the increased exposed area required for vertical deformation of the top wall 3 when the massage airbag 1 switches to the inflated state, ensuring that the top wall 3 can vertically expand and contract in a predetermined manner. The radial width of the wide ring 5 is at least twice that of the narrow ring 6. This ensures that the narrow rings 6 located at the inner and outer edges of the same wide ring 5 do not overlap when the massage airbag 1 switches to the contracted state. By preventing vertical overlap of adjacent narrow rings 6, the number of overlapping layers is reduced, thereby reducing the thickness of the massage airbag 1. Between adjacent wide rings 5, the outer edge of the wide ring 5 located above and the inner edge of the wide ring 5 located below are vertically overlapped, and the radial width of the vertical overlapping area matches the radial width of the narrow ring 6 between the two, ensuring that adjacent wide rings 5 ​​and narrow rings 6 can be stacked flatly.

[0061] In this embodiment, the top wall 3 includes four groups of wide rings 5 ​​and narrow rings 6, the inner edge of the first wide ring 5 is sealed to the periphery of the protrusion 4, the outer edge of the first wide ring 5 is sealed to the outer edge of the first narrow ring 6, the inner edge of the first narrow ring 6 is sealed to the inner edge of the second wide ring 5, and so on. The outer edge of the fourth narrow ring 6 is sealed to the bottom wall 2, so that the bottom wall 2, the protrusion 4 and the four groups of wide rings 5 ​​and narrow rings 6 form the massage airbag 1 by cooperation. During use, the massage airbag 1 is switched to the inflated state by inflation, and the convex point 4 will be lifted upward due to the vertical expansion and deformation of the massage airbag 1, thereby applying a pressing force to the user. During this process, the adjacent wide rings 5 ​​and narrow rings 6 will be unfolded with the connecting edge as the center and guide the massage airbag 1 to expand vertically; the massage airbag 1 is switched to the contracted state by deflating, and the convex point 4 will move downward due to the vertical contraction and deformation of the massage airbag 1, thereby canceling the pressing force on the user. During this process, the adjacent wide rings 5 ​​and narrow rings 6 will be vertically stacked with the connecting edge as the center, and the thickness of the massage airbag 1 is reduced by the mutual fit between the adjacent wide rings 5 ​​and narrow rings 6, thereby reducing the foreign body sensation caused to the user.

[0062] In this embodiment, at least one of the upper magnetic component 22 and the lower magnetic component 23 is a magnet, and the remaining one can be a metal component that can be attracted by a magnet, ensuring that an attractive force can be generated between the upper magnetic component 22 and the lower magnetic component 23.

[0063] The other structures and effects of the airbag cushion described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0064] Example 3:

[0065] Compared with the first or second embodiment, this embodiment provides a mattress.

[0066] The mattress shown in the figure includes an outer cover and a cushion body. The outer cover includes an upper quilted layer 14 and a lower quilted layer 15 that completely enclose the cushion body. The cushion body comprises, from top to bottom, a comfort layer 16, an airbag cushion 17, an airbag securing layer 18, and a support layer 19. The cushion body is provided with a peripheral edge 20, and the rear end of the peripheral edge 20 houses a controller 21 that controls the inflation and deflation of the airbag cushion 17. The rear end of the peripheral edge 20 provides an installation cavity, within which the controller 21 is located. This cavity facilitates installation and maintenance, shortens the distance between the peripheral edge 20 and the airbag cushion 17, facilitates piping installation, and reduces the impact of operating noise from the controller 21 on the user, thus improving the user experience.

[0067] In this embodiment, the size of the airbag cushion 17 can be adjusted as needed so that the laying area of ​​the airbag cushion 17 meets the requirements of the user, which should also be regarded as a specific implementation of this embodiment.

[0068] In this embodiment, the number of airbag cushions 17 can also be adjusted as needed. By setting up multiple independent airbag cushions 17, differentiated massage can be implemented for different body parts of the user, and by setting up two independent airbag cushions 17, independent massage can be provided for multiple users on the same mattress. Both should be regarded as specific implementation methods of this embodiment.

[0069] In this embodiment, the upper quilted layer 14 and the lower quilted layer 15 are fixedly connected at their peripheries and completely wrap the cushion body, thereby protecting and shaping the cushion body.

[0070] In this embodiment, the support layer 19 may be an air cushion layer that can be inflated and deflated to adjust the softness and hardness, or a spring layer, a sponge layer, etc., all of which should be regarded as specific implementations of this embodiment.

[0071] The other structures and effects of the airbag cushion described in this embodiment are consistent with those of the first or second embodiment and will not be described in detail.
