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 include an outer cover and a cushion body. The outer cover includes an upper quilted layer and a lower quilted layer that completely encase the cushion body. The cushion body includes a comfort layer, an airbag cushion, an airbag fixing 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 back and forth through inflation and deflation, thereby providing a pressing force to the user. Existing massage airbags include a bottom wall and a spherical top wall with an upwardly protruding point in the middle of the top wall. When the massage airbag is deflated and switched to a deflated state, the top wall folds irregularly, preventing the top wall from tightly fitting with the bottom wall, resulting in a thicker thickness in the deflated state, which in turn affects the user's sleep experience due to a foreign body sensation. Furthermore, the point cannot rise and fall along the preset path when the massage airbag switches to the inflated state, resulting in an inaccurate pressing action, which affects 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 vertical folding from the center to the outside on the periphery of the top wall. This ensures that the massage airbag can deform vertically and switch between an inflated state and a contracted state, exerting a pressing force on the user, and can also use the folded ring formed by the vertical folding to guide the top wall to reset, effectively reducing the thickness of the massage airbag, reducing the foreign body sensation, and improving the user experience.

[0004] The present invention is achieved through the following method: an airbag cushion comprising a massage airbag, the massage airbag comprising a bottom wall and a vertically deformable top wall, the middle portion of the top wall being raised upward to form a convex point, and the periphery of the top wall being provided with a folded ring formed by repeated vertical folding from the center outward. The massage airbag, upon inflation and deflation, switches between an inflated state, in which adjacent folded rings are vertically extended, and a contracted state, in which adjacent folded rings are horizontally stacked. The structure of the massage airbag is improved, with a folded ring formed by repeated vertical folding from the center outward being provided on the periphery of the top wall. The folded ring can switch between an expanded state and a collapsed state. This ensures that the massage airbag can deform vertically and switch between the inflated and contracted states, applying a pressing force to the user, while also utilizing the folded ring to guide and accurately reposition the top wall. This ensures pressing accuracy by reducing horizontal offset of the convex point, and reduces the thickness of the massage airbag in the contracted state by guiding the top wall to accurately reposition, thereby improving the user experience by reducing the foreign body sensation.

[0005] Preferably, the vertical projections of the folds are offset from each other, and the corresponding edges of adjacent folds are sealed. Adjacent folds have different sizes, which can be used to seal the corresponding edges of adjacent folds to position each fold, thereby ensuring that the top wall can be accurately reset to a preset shape that fits the bottom wall, reducing the thickness of the massage airbag to reduce the foreign body sensation. The vertical displacement between adjacent folds can also be used to achieve vertical deformation of the top wall, thereby ensuring that the protrusion moves upward and applies a pressing force to the user.

[0006] Preferably, the cross-sectional profile of the fold is V-shaped, and the fold is arranged along the top wall from the center to the outside. The fold is arranged from the inside to the outside, and the corresponding edges of adjacent folds are sealed. This not only ensures the sealing of the top wall, facilitates the pressure adjustment of the massage airbag, but also ensures that the fold has good deformation recovery performance, playing a guiding role in the return of the top wall.

[0007] Preferably, when the massage airbag is in its deflated state, the folds abut against the bottom wall, causing the mid-angle of the fold to become acute and reducing the height difference between the two edges. The mid-heights and edges of adjacent folds are set at the same height, ensuring that all folds are at the same height and close to the bottom wall, effectively reducing the thickness of the massage airbag and, in turn, minimizing the foreign body sensation.

[0008] Preferably, when the massage airbag is inflated, the middle portion of the top wall bulges upward, forming a conical shape with a narrower top and a wider bottom. This shifts the angle of the fold to an obtuse angle and increases the height difference between the two edges. As the fold gradually decreases in size from the outside to the inside, the fold expands and the top wall bulges to form a conical shape. This ensures that the pressing force is concentrated inward and acts on the user through the raised point. It also effectively improves the resistance of the massage airbag top to horizontal deformation, ensuring that the raised point rises and falls in the vertical direction.

[0009] Preferably, when the massage airbag is in its deflated state, the folds abut against the bottom wall, causing the mid-angle of the fold to become acute and reducing the height difference between the two edges. The mid-heights and edges of adjacent folds are set at the same height, ensuring that all folds are at the same height and close to the bottom wall, effectively reducing the thickness of the massage airbag and, in turn, minimizing the foreign body sensation.

[0010] Preferably, the folds have the same height, and when the massage airbags are switched to the contracted state, the middle of the folds are joined together to form a flat support surface. The folds are in an inverted V-shape, with the middle section of the folds rising upward and joining together to form the support surface, which can not only effectively support the user, but also reduce the foreign body sensation and improve lying comfort.

[0011] Preferably, the folds have the same radial width, so that they experience the same vertical deformation amplitude when the massage airbags switch to the inflated state. The corresponding edges of adjacent folds have the same diameter, ensuring a sealed connection. The same radial width ensures that each fold can expand synchronously and guide the vertical elevation of the protrusions, effectively reducing the horizontal deviation of the protrusions.

[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, at least one group of magnetic components is provided between the top wall and the bottom wall, and the magnetic components include an upper magnetic component provided on the top wall and a lower magnetic component provided on the bottom wall. When the massage airbag is deflated, the upper magnetic component descends and is vertically attracted to the lower magnetic component to guide the massage airbag to reset from the inflated state in which the top wall bulges upward to the contracted state in which the top wall is moved closer to the bottom wall. The structure of the massage airbag is improved, and a magnetic component that can generate an attractive force is set between the top wall and the bottom wall of the massage airbag. The magnetic component includes an upper magnetic component and a lower magnetic component respectively arranged on the top wall and the bottom wall. The vertical attractive force formed between the upper magnetic component and the lower magnetic component is used to guide the top wall to move toward the bottom wall in the vertical direction. This can not only guide the massage airbag to accurately reset from the inflated state to the contracted state, and thereby reduce the foreign body sensation and improve the lying experience by reducing the thickness of the massage airbag, but also use the attractive force to drive the top wall to move toward the bottom wall and assist the massage airbag to quickly exhaust, thereby increasing the massage frequency and improving the massage comfort by improving the inflation and deflation efficiency.

[0016] Preferably, the bottom surface of the upper magnetic member is vertically aligned with the top surface of the lower magnetic member and has oppositely charged polarities to limit horizontal deviation of the top wall during reset and switching. A vertically arranged attractive force is generated between the upper and lower magnetic members, ensuring that the top wall converges toward the bottom wall along a vertical path, thereby ensuring that the top wall folds in a predetermined manner, horizontally correcting any deformation of the top wall, preventing localized multiple overlaps of the top wall due to horizontal deviation, and ensuring that the center of the top wall is always vertically aligned with the center of the bottom wall.

[0017] Preferably, the magnetic assembly is a set, comprising an upper magnetic member positioned in the middle of the top portion and a lower magnetic member positioned in the middle of the bottom wall. The upper and lower magnetic members, when attracted to each other, guide the middle of the top wall toward the middle of the bottom wall, ensuring that all areas of the top wall are evenly stressed and fold in a predetermined manner, thereby reducing the thickness of the massage airbags and eliminating the foreign body sensation.

[0018] Preferably, the magnetic assembly comprises multiple groups, including upper magnetic components equidistantly spaced along the circumference of the top wall and lower magnetic components equidistantly spaced along the circumference of the bottom wall, wherein the upper magnetic components are vertically aligned with the lower magnetic components. The multiple upper magnetic components are disposed on various circumferential regions of the top wall, and lower magnetic components corresponding to the upper magnetic components are disposed on various circumferential regions of the bottom wall, so that each region of the top wall can be guided by the corresponding upper magnetic components and the lower magnetic components to move closer to and fit into the corresponding region of the bottom wall, thereby ensuring that the top wall can be folded according to a preset plan and eliminating the foreign body sensation by reducing the thickness of the massage airbag.

[0019] Preferably, the massage airbag is inflated and accumulates a preload force for vertical expansion. When the preload force overcomes the combined attraction force between the upper and lower magnetic parts, the protrusions spring upward under the influence of the preload force, thereby increasing the speed at which the protrusions move upward to enhance the massage force. When the massage airbag is inflated, the massage airbag uses the combined attraction force to limit vertical deformation and accumulate preload force. The preload force increases as the air pressure in the massage airbag increases, allowing the upper magnetic part to detach from the lower magnetic part when the preload force is greater than the combined attraction force. The massage airbag drives the protrusions upward rapidly through the top wall and increases the pressing force applied to the user, effectively enhancing massage comfort.

[0020] Preferably, the massage airbag comprises at least two vertically stacked unit bladders, each connected by a through-hole. The unit bladders are interconnected and can deform vertically between an inflated and deflated state. The unit bladders are interconnected and can deform vertically synchronously. Massage is performed by driving the raised points up and down. The walls of each unit bladder are smoothly stacked by the magnetic assembly, effectively eliminating multiple wall overlaps and enabling rapid degassing. The folded ring is located on the top surface of the unit bladder.

[0021] 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.

[0022] The beneficial effects of the present invention are as follows: 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 vertical folding from the center to the outside. The folded ring can switch between an expanded state and a collapsed state, ensuring that the massage airbag can deform vertically and switch between an inflated state and a collapsed state, exerting a pressing force on the user. The folded ring formed by the vertical folding can also guide and accurately reset the top wall, ensuring pressing accuracy by reducing the horizontal deviation of the protrusion, and reducing the thickness of the massage airbag in the collapsed state by guiding the top wall to accurately reset, thereby improving the user experience by reducing the foreign body sensation.

[0023] The massage airbag structure is improved. A magnetic attraction component that can generate an attraction force is provided between the top and bottom walls of the massage airbag. The magnetic attraction component includes an upper magnetic member and a lower magnetic member respectively disposed on the top and bottom walls. A vertical attraction force is generated between the upper and lower magnetic members to guide the top wall to move toward the bottom wall in the vertical direction. This can not only guide the massage airbag to accurately return from an inflated state to a deflated state, thereby reducing the foreign body sensation and improving the lying experience by reducing the thickness of the massage airbag, but also utilize the attraction force to drive the top wall to move toward the bottom wall accurately and assist in the rapid deflating of the massage airbag, thereby increasing the massage frequency and improving the massage comfort by improving the inflation and deflation efficiency.

[0024] When the massage airbag is inflated, the massage airbag uses suction force to limit vertical deformation and accumulate pre-tightening force. The pre-tightening force will increase 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 pre-tightening force is greater than the suction force. The massage airbag drives the convex point to bounce upward quickly through the top wall and increases the pressing force applied to the user, effectively improving the massage comfort.

Modes for Carrying Out the Invention

[0039] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0040] Example 1:

[0041] This embodiment provides an airbag cushion.

[0042] 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 5 formed by repeated vertical folding from the middle to the outside. The massage airbag 1 is switched between an inflated state in which adjacent folded rings 5 ​​are vertically expanded and a contracted state in which adjacent folded rings 5 ​​are horizontally stacked by inflation and deflation. The structure of the massage airbag 1 is improved, and a folded ring 5 is provided on the periphery of the top wall 3, which is formed by repeated vertical folding from the center to the outside. The folded ring 5 can switch between an expanded state and a collapsed state, which not only ensures that the massage airbag 1 can be vertically deformed and switch between an inflated state and a contracted state, exerting a pressing force on the user, but also utilizes the folded ring 5 formed by the vertical folding to guide and accurately reset the top wall 3, thereby ensuring the accuracy of pressing by reducing the horizontal offset of the protrusion 4, and reducing the thickness of the massage airbag 1 in the contracted state by guiding the top wall 3 to accurately reset, thereby improving the user experience by reducing the foreign body sensation.

[0043] In this embodiment, the vertical projections of the folds 5 are offset from each other, and the corresponding edges of adjacent folds 5 are sealed. Between adjacent folds 5, the inner diameter of the outer fold 5 is the same as the outer diameter of the inner fold 5, so that the adjacent folds 5 can be sealed together through their corresponding edges, ensuring the sealing performance of the inner cavity of the massage airbag 1 and facilitating the control of the softness and hardness of the massage airbag 1 by adjusting the air pressure.

[0044] In this embodiment, the cross-sectional profile of the fold ring 5 is V-shaped, and the fold ring 5 is arranged along the top wall 3 from the center to the outside. The fold ring 5 includes an annular inner edge portion and an annular outer edge portion, and the angle between the inner edge portion and the outer edge portion is variable:

[0045] When the massage airbag 1 is in the contracted state, the folded ring 5 is in the folded state, and the angle between the inner edge and the outer edge is acute. The folded ring 5 ensures close contact with the bottom wall 2 by reducing the height difference between the edges of the folded ring 5, and further reduces the foreign body sensation by reducing the thickness of the massage airbag 1, thereby ensuring the comfort of the user lying down;

[0046] When the massage airbag 1 is inflated, the folding ring 5 is in an expanded state, and the angle between the inner edge and the outer edge is an obtuse angle (as shown in FIG3 ). The middle part of the top wall 3 bulges upward, and the inner and outer edges of each folding ring 5 tend to be flat and guide the massage airbag 1 to deform into a cone shape that is smaller at the top and larger at the bottom. The folding ring 5 is expanded to allow the middle part of the top wall 3 to obtain space for upward bulging, and then the convex point 4 is used to apply a pressing force to the user, thereby improving the massage comfort.

[0047] In this embodiment, the folds 5 have the same height and radial width, so that each fold 5 has the same vertical deformation amplitude when expanded. By setting the same vertical deformation amplitude, the same deformation force is ensured for each fold 5, thereby ensuring that each fold 5 can deform synchronously, preventing the situation where individual folds 5 cannot recover in time, causing the protrusions 4 to shift horizontally, thereby affecting the pressing operation of the protrusions 4. In addition, when the massage airbag 1 switches to the contracted state, the middle portion of the fold 5 is spliced ​​to form a flat supporting surface, and the top surface of the protrusion 4 is flush with the supporting surface, thereby reducing the foreign body sensation by increasing the supporting surface area.

[0048] In this embodiment, there are at least three folding rings 5, and they are arranged to expand in diameter from the middle to the outside. The inner edge of the first ring is sealed to the outer edge of the protrusion 4, the inner edge of the second ring is sealed to the outer edge of the first ring, the inner edge of the third ring is sealed to the outer edge of the second ring, and the outer edge of the third ring is sealed to the peripheral edge of the bottom wall 2. During use: when the massage airbag 1 switches to the inflated state, the inner and outer edges of the first, second and third rings are synchronously expanded and drive the protrusion 4 to rise upward along the vertical path, ensuring that the protrusion 4 can accurately contact the user's preset position; when the massage airbag 1 switches to the contracted state, the inner and outer edges of the first, second and third rings are synchronously retracted and drive the protrusion 4 to fall downward along the vertical path, ensuring that the massage airbag 1 can be accurately reset and prepared for lifting again.

[0049] In this embodiment, the airbag cushion 14 includes a base with an internal air conduit. The massage airbags 1 communicate with the air conduit via a vent 10 located on the top surface of the base. The air conduit is equipped with an air nozzle that communicates with an external controller 18. The airbag cushions 14 share a common base, and the air conduit is disposed within the base. The air conduit is connected to the controller 18 and the corresponding massage airbag 1 via the air nozzle and vent 10, respectively. This allows the controller 18 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.

[0050] In this embodiment, the base comprises an integral bottom layer 6 and an airway layer 7 overlying the bottom layer 6 (as shown in FIG4 ). The airway layer 7 comprises densely arranged unit sheets 8 and elongated segments 9 spanning adjacent unit sheets 8 . The unit sheets 8 form the bottom wall 2 . The vents 10 are provided on the unit sheets 8 (as shown in FIG5 ). The periphery of the airway layer 7 is heat-fused to the bottom layer 6 , so that the airway layer 7 and the bottom layer 6 enclose the airway conduit. Both the bottom layer 6 and the airway layer 7 are integral sheet structures. The airway layer 7 comprises unit sheets 8 and elongated segments 9 . The airway layer 7 is heat-fused to the bottom layer 6 via the edges of the unit sheets 8 and elongated segments 9 , so that the airway conduit is enclosed between the airway layer 7 and the bottom layer 6 . The top surface of the unit sheets 8 forms the bottom wall 2 , and the unit sheets 8 are provided with vents 10 , so that the airway conduit communicates with the massage airbag 1 through the vents 10 .

[0051] In this embodiment, the airbag cushion 14 includes at least one section, sequentially divided from front to back, comprising a shoulder support area, a waist support area, a hip support area, and a leg support area. 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 14 is divided into multiple sections, 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 implementation of this embodiment.

[0052] It is understandable that the number of folding rings 5 ​​included in the top wall 3 can be adjusted as needed, for example, set to two, four, five, etc., which should all be regarded as specific implementations of this embodiment.

[0053] Example 2:

[0054] Compared with the first embodiment, this embodiment provides another airbag cushion.

[0055] As shown in Figure 6, an airbag cushion is provided with at least one group of magnetic components between the top wall 3 and the bottom wall 2. The magnetic components include an upper magnetic component 19 provided on the top wall 3 and a lower magnetic component 20 provided on the bottom wall 2. When the massage airbag 1 is deflated, the upper magnetic component 19 descends and vertically engages with the lower magnetic component 20 to guide the massage airbag 1 to reset from the inflated state in which the top wall 3 bulges upward to the contracted state in which the top wall 3 moves closer to the bottom wall 2. A magnetic attraction component that can generate an attraction force is provided between the top wall 3 and the bottom wall 2 of the massage airbag 1. The magnetic attraction component includes an upper magnetic component 19 and a lower magnetic component 20 respectively arranged on the top wall 3 and the bottom wall 2. A vertical attraction force is formed between the upper magnetic component 19 and the lower magnetic component 20 to guide the top wall 3 to move toward the bottom wall 2 in the vertical direction. This can not only guide the massage airbag 1 to accurately reset from the inflated state to the contracted state, and thereby reduce the foreign body sensation and enhance the lying experience by reducing the thickness of the massage airbag 1, but also utilize the attraction force to drive the top wall 3 to move toward the bottom wall 2 and assist the massage airbag 1 to quickly exhaust, thereby increasing the massage frequency and improving the massage comfort by improving the inflation and deflation efficiency.

[0056] When the massage airbag 1 is in a contracted state, the protrusion 4 is arranged in contact with the bottom wall 2, the upper magnetic part 19 and the lower magnetic part 20 are vertically attracted to each other, the folding ring 5 is in a folded state, the angle between the inner edge and the outer edge of the folding ring 5 is an acute angle, and the two side edges of the folding ring 5 are arranged at the same height. The folding rings 5 ​​are sequentially arranged in the same plane from the middle to the outside, which not only ensures that the massage airbag 1 has a smaller thickness and effectively reduces the foreign body sensation, but also makes the vertical projections of each folding ring 5 staggered, ensuring that each folding ring 5 has space to switch to the expanded state, preventing mutual squeezing and interference between adjacent folding rings 5. When the massage airbag 1 is in an inflated state (as shown in FIG7 ), the convex point 4 is located above the middle part of the bottom wall 2, the upper magnetic part 19 is suspended above the lower magnetic part 20, and the angle between the inner edge and the outer edge of the folding ring 5 is an obtuse angle. The folding ring 5 is in an expanded state, and the height offset setting of the edges on both sides of the folding ring 5 ensures that the adjacent folding rings 5 ​​can achieve synchronous linkage by pulling the corresponding edges, and also utilizes the folding rings 5 ​​that are arranged to expand in diameter from the middle to the outside to bridge between the convex point 4 and the periphery of the bottom wall 2 to ensure that the inner cavity of the massage airbag 1 is sealed and isolated from the outside.

[0057] When the massage airbag 1 switches from an inflated state to a deflated state by deflating, the massage airbag 1 contracts by reducing the air pressure, and the upper magnetic component 19 will descend with the top wall 3 and be vertically attracted to the lower magnetic component 20. The magnetic component can drive the top wall 3 to accelerate towards the bottom wall 2, thereby improving the exhaust efficiency of the massage airbag 1, and increasing the massage frequency by shortening the exhaust time. It can also play a centering role in the descending process of the top wall 3, preventing the top wall 3 from overlapping on the side due to the horizontal offset of the protrusion 4, ensuring that the folding ring 5 can be accurately reset to the folded state and fit the bottom wall 2, preparing to guide the protrusion 4 to rise vertically again, and ensuring that the protrusion 4 always performs the lifting and lowering action along the vertical path.

[0058] When the massage airbag 1 switches from a contracted state to an inflated state through inflation, the top wall 3 and the bottom wall 2 will maintain a fixed relative position due to the attractive force between the upper magnetic part 19 and the lower magnetic part 20, 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 19 will move upward under the drive of the top wall 3 and disengage from the lower magnetic part 20, 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. During this process, the middle part of the top wall 3 bulges upward, and the protrusion 4 drives the surrounding folded rings 5 ​​to switch from a folded state to an expanded state. By driving the edges of the folded rings 5 ​​on both sides to separate vertically, space is created for the protrusion 4 to rise. The folded rings 5 ​​in the top wall 3 will be pulled vertically from the middle to the outside in turn and switched to the expanded state, so that the massage airbag 1 changes into a cone shape with a smaller top and a larger bottom.

[0059] In this embodiment, there are at least three folding rings 5, and they are expanded in diameter from the middle to the outside. The inner edge of the first ring is sealed to the outer edge of the protrusion 4, the inner edge of the second ring is sealed to the outer edge of the first ring, the inner edge of the third ring is sealed to the outer edge of the second ring, and the outer edge of the third ring is sealed to the peripheral edge of the bottom wall 2. During use: when the massage airbag 1 switches to the inflated state, the inner and outer edges of the first, second and third rings unfold and drive the protrusion 4 to rise upward along the vertical path, ensuring that the protrusion 4 can accurately contact the user's preset position; when the massage airbag 1 switches to the contracted state, the inner and outer edges of the first, second and third rings are synchronously retracted and drive the protrusion 4 to fall downward along the vertical path, ensuring that the massage airbag 1 can be accurately reset and prepared for rising again.

[0060] In this embodiment, the magnetic assembly is a set, including an upper magnetic component 19 disposed in the middle of the top and a lower magnetic component 20 disposed in the middle of the bottom wall 2. The middle portion of the top wall 3 is raised upward to form a convex cavity, and the outer wall of the convex cavity forms the convex point 4. The upper magnetic component 19 is installed at the lower end of the convex cavity so that the upper magnetic component 19 and the convex point 4 move synchronously. The top surface of the convex point 4 is spherical with an upward bulge in the middle, which can not only effectively transmit the pressing force, but also can match the user's performance through its own deformation, thereby improving the comfort of massage.

[0061] In this embodiment, the upper magnetic member 19 is mounted at the lower end of the convex cavity via an upper fixing member (as shown in FIG8 ), and the lower magnetic member 20 is mounted at the middle portion of the bottom wall 2 via a lower fixing member. This not only positions the upper magnetic member 19 and the lower magnetic member 20, ensuring that they are vertically aligned, but also limits the posture of the upper magnetic member 19 and the lower magnetic member 20, ensuring that the bottom surface of the upper magnetic member 19 is always facing the top surface of the lower magnetic member 20, and ensuring that an attractive force is generated between the bottom surface of the upper magnetic member 19 and the top surface of the lower magnetic member 20. The periphery of the upper fixing member is adhered to the periphery of the lower end of the convex cavity, and the periphery of the lower fixing member is adhered to the middle portion of the bottom wall 2.

[0062] In this embodiment, the convex cavity is connected to the massage airbag 1 through the lower port. The massage airbag 1 inflates the convex cavity and increases the hardness of the convex point 4. A gap is reserved between the periphery of the lower port of the convex cavity and the upper fixing part to facilitate the connection between the convex cavity and the massage airbag 1. It ensures that the convex point 4 can harden when the massage airbag 1 is inflated, which is convenient for transmitting the pressing force to the user, and also ensures that the convex point 4 can soften when the massage airbag 1 is deflated, effectively eliminating the foreign body sensation caused to the user.

[0063] In this embodiment, the massage airbag 1 is inflated and accumulates a preload force for vertical expansion. When the preload force overcomes the attraction force between the upper magnetic part 19 and the lower magnetic part 20, the protrusion 4 springs upward under the drive of the preload force, thereby increasing the massage force by increasing the speed at which the protrusion 4 moves upward. When the massage airbag 1 is inflated, the massage airbag 1 uses the attraction force to limit vertical deformation and accumulate preload force. The preload force increases as the air pressure in the massage airbag 1 increases, so that the upper magnetic part 19 can be separated from the lower magnetic part 20 when the preload force is greater than the attraction force. The massage airbag 1 drives the protrusion 4 to quickly spring upward through the top wall 3 and increases the pressing force applied to the user, effectively improving the massage comfort and effectively solving the problem of insufficient pressing force applied by the massage airbag 1 on the user.

[0064] In this embodiment, at least one of the upper magnetic component 19 and the lower magnetic component 20 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 19 and the lower magnetic component 20.

[0065] In this embodiment, the top wall 3 is formed by integral processing, so that adjacent fold rings 5 ​​are sealed and connected, which not only improves the sealing reliability, but also facilitates processing and ensures that the shape of the fold ring 5 meets the use requirements.

[0066] It can be understood that a filler can also be provided in the convex cavity, and the upper fixing piece blocks the lower port of the convex cavity and seals the filler. The filler is used to increase the hardness of the protrusion 4, which is convenient for transmitting the pressing force. It can also reduce the noise caused by material deformation by limiting the deformation of the protrusion 4, thereby improving the silent performance, and should also be regarded as a specific implementation method of this embodiment.

[0067] It is understandable that the number of folding rings 5 ​​included in the top wall 3 can be adjusted as needed, for example, set to two, four, five, etc., which should all be regarded as specific implementations of this embodiment.

[0068] Example 3:

[0069] Compared with the second embodiment, this embodiment provides another massage airbag 1 structure.

[0070] As shown in Figures 9 and 10, a massage airbag 1 includes at least two vertically stacked unit bags 21. Adjacent unit bags 21 are connected by through holes. The massage airbag 1 can be vertically expanded and contracted between an inflated state and a deflated state.

[0071] In this embodiment, the unit capsules 21 are arranged to be vertically stacked. When the massage airbag 1 switches to the folded state by deflating, the upper magnetic component 19 and the lower magnetic component 20 are vertically attracted and drive the top wall and the bottom wall of each unit capsule 21 to be vertically stacked, which not only ensures that the protrusion 4 can move downward accurately in the vertical direction, and the massage airbag 1 is folded in a preset manner and realizes vertical expansion and contraction, but also can use the suction force to increase the exhaust speed of the massage airbag 1, thereby improving the massage comfort by increasing the massage frequency.

[0072] The other structures and effects of the massage airbag 1 described in this embodiment are consistent with those in the second embodiment and will not be described in detail.

[0073] Example 4:

[0074] Compared with the second or third embodiment, this embodiment provides another massage airbag 1 structure.

[0075] As shown in FIG11 , a massage airbag 1 includes multiple groups of magnetic components, wherein the upper magnetic components 19 are equidistantly spaced along the circumference of the top wall 3, and the lower magnetic components 20 are equidistantly spaced along the circumference of the bottom wall 2. The upper magnetic components 19 and the lower magnetic components 20 are vertically aligned one by one. The multiple upper magnetic components 19 are placed on the circumferential regions of the top wall 3, and the lower magnetic components 20 corresponding to the upper magnetic components 19 are provided on the circumferential regions of the bottom wall 2, so that the regions of the top wall 3 can be guided by the corresponding upper magnetic components 19 and the lower magnetic components 20 to move closer to and fit in the corresponding regions of the bottom wall 2, ensuring that the top wall 3 can be folded according to the preset plan, thereby eliminating the foreign body sensation by reducing the thickness of the massage airbag 1.

[0076] In this embodiment, there are three groups of magnetic components, which are circumferentially spaced apart in the massage airbag 1. The diameter of the inscribed circle formed by the magnetic components is half the diameter of the massage airbag 1, ensuring that the magnetic components are arranged in the center of the corresponding side area of ​​the massage airbag 1, effectively improving the effect of guiding deformation.

[0077] It can be understood that the number of the magnetic components can also be two groups, four groups, five groups, etc., which should all be regarded as specific implementation methods of this embodiment.

[0078] The other structures and effects of the massage airbag described in this embodiment are consistent with those of the second or third embodiment and will not be described in detail.

[0079] Embodiment 5:

[0080] Compared with the first embodiment, the second embodiment, the third embodiment or the fourth embodiment, this embodiment provides a mattress.

[0081] The mattress shown in Figures 12 and 13 comprises an outer cover and a cushion body. The outer cover comprises an upper quilted layer 11 and a lower quilted layer 12 that completely enclose the cushion body. The cushion body comprises, arranged from top to bottom, a comfort layer 13, an airbag cushion 14, an airbag securing layer 15, and a support layer 16. The cushion body is provided with a peripheral edge 17, and a controller 18 for controlling the inflation and deflation of the airbag cushion 14 is housed within the rear end of the peripheral edge 17. The rear end of the peripheral edge 17 provides an installation cavity, within which the controller 18 is located. This cavity facilitates installation and maintenance, shortens the distance between the peripheral edge 17 and the airbag cushion 14, facilitating piping installation, and reduces the impact of operating noise from the controller 18 on the user, thus enhancing the user experience.

[0082] In this embodiment, the size of the airbag cushion 14 can be adjusted as needed so that the laying area of ​​the airbag cushion 14 meets the requirements of the user, which should also be regarded as a specific implementation of this embodiment.

[0083] In this embodiment, the number of airbag cushions 14 can also be adjusted as needed. By setting up multiple independent airbag cushions 14, differentiated massage can be implemented for different body parts of the user, and by setting up two independent airbag cushions 14, independent massage can be provided for multiple users on the same mattress. Both should be regarded as specific implementation methods of this embodiment.

[0084] In this embodiment, the airbag fixing layer 15 serves to fix the airbag cushion 14. The airbag cushion 14 is adhered and fixed to the top surface of the airbag fixing layer 15. The bottom surface of the airbag fixing layer 15 is fixed to the top surface of the support layer 16, ensuring that the relative position between the airbag cushion 14 and the support layer 16 is fixed.

[0085] In this embodiment, the upper quilted layer 11 and the lower quilted layer 12 are fixedly connected at their peripheries and completely wrap the cushion body, thereby protecting and shaping the cushion body.

[0086] In this embodiment, the support layer 16 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.

[0087] The other structures and effects of the airbag cushion described in this embodiment are consistent with those of the first, second, third or fourth embodiments and will not be described in detail.
