Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a supporting airbag, a supporting airbag cushion and a mattress. Background Art

[0002] Existing support airbags include a bladder body, which comprises a number of vertically stacked and interconnected unit cavities. The sidewalls of these unit cavities are provided with annular folds, which allow the bladder to expand and contract during inflation and deflation. The sidewalls of the unit cavities located on either side of the folds open and close around the folds, resulting in a large vertical deformation range for the bladder body. This not only causes significant deformation during firmness adjustment, leading to depressions or bulges in the center of the mattress, affecting aesthetics, but also requires a long adjustment time due to the large volume of air inflated and deflated during firmness adjustment, resulting in loud noise and a negative user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the present invention provides a support airbag, a support airbag cushion and a mattress. The side walls of the airbag include outer arc segments and inner arc segments that are vertically alternately arranged, which effectively reduce the volume change of the airbag during inflation and deflation, ensuring that the airbag can achieve softness and hardness adjustment with relatively small deformation, and effectively improve the softness and hardness adjustment speed, thereby enhancing the user experience.

[0004] The present invention is realized in the following manner: a supporting airbag, comprising a bag body, the bag body comprising a plurality of vertically stacked and mutually connected unit cavities, the side wall of the bag body comprising outer arc segments and inner arc segments vertically alternately arranged, the outer arc segments enclosing the unit cavities, the inner arc segments spanning the corresponding end edges of adjacent outer arc segments, so that the vertical cross-sectional profile of the bag body side wall is in the shape of a continuous curve that bends back and forth. The side wall of the bag body comprises outer arc segments and inner arc segments vertically alternately arranged, and the outer arc segments and the inner arc segments are used to form an S-shaped curve, thereby improving the bag body's resistance to vertical deformation and effectively reducing the volume change of the bag body during inflation and deflation, ensuring that the bag body can achieve softness and hardness adjustment with relatively small deformation, preventing the mattress from experiencing large fluctuations due to inflation and deflation of the bag body, and also improving the softness and hardness adjustment speed by reducing the amount of air required for adjusting the softness and hardness of the bag body, and improving the user experience.

[0005] Preferably, the corresponding end edges of the outer arc segment and the inner arc segment are smoothly connected. The corresponding edges of the outer arc segment and the inner arc segment are arranged tangentially to each other, ensuring a smooth connection between the two, preventing creases from occurring at the connection between the two, and effectively improving the resistance to vertical deformation.

[0006] Preferably, the diameter of the end edge of the outer arc segment is smaller than the diameter of its middle part, and the diameters of the top edge and the bottom edge of the outer arc segment are smaller than the diameter of the area between the top edge and the bottom edge of the outer arc segment, so that the outer arc segment is shaped like a waist drum with the middle part bulging outward. By setting differentiated diameters, it has good resistance to radial deformation and resistance to vertical deformation, which not only ensures the vertical expansion and contraction of the capsule along its axis, but also effectively reduces the deformation of the capsule when the softness and hardness are adjusted.

[0007] Preferably, the middle diameters of the outer arc segments are the same, and the middle diameters of all outer arc segments are the same and are coaxially arranged with each other, ensuring that the capsule can form a cylindrical outline through the middle of the outer arc segment, ensuring that the outer contour of the capsule is regular and can be tightly arranged and used.

[0008] Preferably, the diameter of the end edge of the inner arc segment is larger than its middle diameter, and the diameters of the top and bottom edges of the inner arc segment are larger than the middle diameter of the inner arc segment between the top and bottom edges, so that the inner arc segment is concave inward in the middle, which ensures that the end edge of the inner arc segment can be smoothly connected with the end edge of the outer arc segment tangentially, effectively eliminating the creases on the side wall of the capsule, and by setting differentiated diameters, it has good resistance to radial deformation and vertical deformation, which ensures that the capsule can expand and contract vertically along its axis, and effectively reduces the deformation of the capsule when the softness or hardness is adjusted.

[0009] Preferably, the middle diameters of the inner arc segments are the same, and the middle diameters of all inner arc segments are the same and are coaxially arranged to ensure that the capsule will not swing easily due to the small middle diameter of the inner arc segment, and ensure that the axis of the capsule always remains vertically straight, thereby ensuring that the supporting force is always applied upward.

[0010] Preferably, the middle diameter of the outer arc segment is A, the middle diameter of the inner arc segment is B, 0.8≤B / A≤0.9, which ensures that the capsule has good resistance to vertical deformation by limiting the difference in the middle diameters of the outer arc segment and the inner arc segment, thereby reducing the height change of the capsule when the hardness is adjusted. It also increases the difference in the middle diameters of the outer arc segment and the inner arc segment to increase the radial width of the vertical projection of the side wall of the capsule, thereby obtaining better resistance to radial deformation. It also increases the middle diameter of the inner arc segment to improve the anti-bending performance of the capsule, ensuring that the axis of the capsule always remains vertically straight.

[0011] Preferably, the vertical radial cross-sectional radius of the outer arc segment is R1, and the vertical radial cross-sectional radius of the inner arc segment is R2, 0.16≤R2 / R1≤0.33, which ensures that the outer arc segment has a larger diameter so that the outer arc segment can be vertically straight in the region, thereby improving the resistance to vertical deformation by reducing the number of unit cavities, and also ensures that the inner arc segment can smoothly connect with adjacent outer arc segments, and prevents excessive compression deformation when the capsule is deflated by eliminating creases, and utilizes its own resistance to vertical deformation to reduce the weight of the capsule after deflation, thereby effectively maintaining the capsule contour.

[0012] Preferably, the radian angle of the vertical radial cross section of the outer arc segment is C, 150°≤C≤170°. By increasing the radian angle, the profile of the outer arc segment on the vertical radial cross section tends to be linear, thereby effectively improving the vertical deformation resistance. The vertical radial cross section refers to the surface that simultaneously covers the capsule axis and any radial line of the capsule.

[0013] Preferably, the radian angle of the vertical radial section of the inner arc segment is D, 130°≤D≤150°. By increasing the radian angle, the contour of the inner arc segment on the vertical radial section tends to be linear, thereby effectively improving the resistance to vertical deformation.

[0014] Preferably, a buffer cavity is provided on the top of the capsule, and the top wall of the buffer cavity forms a curved supporting surface. The buffer cavity uses its own deformation to change the contour of the supporting surface, ensuring that the supporting surface matches the user's surface, thereby effectively improving the support effect.

[0015] A support cushion comprises air cells and a base, with the air cells mounted in a matrix. The matrix arrangement of the air cells ensures effective support for all areas of the user's body. Air passages connecting adjacent air cells allow for synchronous regulation of the air pressure within them, thereby controlling the softness and hardness of each air cell, improving the user experience. The base supports and positions the air cells, ensuring their relative positions are fixed and preventing interference.

[0016] A mattress comprises a support bladder, a position-limiting pad enclosing the support bladder, and an outer cover comprising the support bladder and the position-limiting pad. The position-limiting block clamps, positions, and protects the support bladder, ensuring that the support bladder is adjusted in position by inflation and deflation, thereby enhancing the comfort of the mattress. The outer cover encloses the support bladder and the position-limiting pad, positioning and protecting them.

[0017] The beneficial effects of the present invention are as follows: the side wall of the bladder includes outer arc segments and inner arc segments that are vertically alternately arranged, and the outer arc segments and the inner arc segments are used to form an S-shaped curve, thereby improving the bladder's resistance to vertical deformation and effectively reducing the volume change of the bladder during inflation and deflation, ensuring that the bladder can adjust its hardness with relatively small deformation, preventing the mattress from experiencing large fluctuations due to inflation and deflation of the bladder, and also improving the hardness adjustment speed by reducing the amount of air required for adjusting the hardness of the bladder, thereby improving the user experience.

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] This embodiment provides a support airbag.

[0026] As shown in the figure, the support airbag includes a bag body, which includes a plurality of vertically stacked and interconnected unit cavities 1. The sidewalls of the bag body include outer arc segments 3 and inner arc segments 4 arranged alternately in vertical direction. The outer arc segments 3 enclose the unit cavities 1, and the inner arc segments 4 span the corresponding end edges of adjacent outer arc segments 3, so that the vertical cross-sectional profile of the bag body sidewall is in the shape of a continuous curve that bends back and forth. The sidewalls of the bag body include outer arc segments 3 and inner arc segments 4 arranged alternately in vertical direction. The outer arc segments 3 and inner arc segments 4 are used to form an S-shaped curve, thereby improving the bag body's resistance to vertical deformation and effectively reducing the volume change of the bag body during inflation and deflation. This ensures that the bag body can achieve softness and hardness adjustment with minimal deformation, preventing the mattress from experiencing large fluctuations due to inflation and deflation of the bag body. It also increases the speed of softness and hardness adjustment by reducing the amount of air required to adjust the softness and hardness of the bag body, thereby improving the user experience.

[0027] In this embodiment, the vertical radial cross-sectional profile of the sac side wall is S-shaped, which is formed by alternating outer arc segments 3 and inner arc segments 4. By utilizing the continuous curved surface to eliminate creases, the S-shaped sac side wall has a smooth and continuous curved surface, which effectively disperses the force and ensures that it has good resistance to vertical deformation. The vertical projection of the S-shaped sac side wall has a large radial width, and the radial width is effectively utilized to improve its resistance to radial deformation. By increasing the value of the parameter B / A to increase the middle diameter of the inner arc segment 4, it is prevented that the sections of the sac side wall are prone to swinging due to too small a diameter, ensuring that the sac axis always remains vertically straight, thereby ensuring that the sac has good vertical pressure-bearing performance.

[0028] In this embodiment, the corresponding end edges of the outer arc segment 3 and the inner arc segment 4 are smoothly connected, and the corresponding end edges of adjacent outer arc segments 3 and inner arc segments 4 are tangentially arranged to each other, which not only ensures smooth connection, but also effectively transmits the force, prevents concentrated force bending due to the formation of creases between the corresponding end edges of the outer arc segment 3 and the inner arc segment 4, and ensures that the capsule has good resistance to both vertical deformation and radial deformation.

[0029] In this embodiment, the diameter of the end edge of the outer arc segment 3 is smaller than its middle diameter, and the middle diameters of all outer arc segments 3 are the same, so that the capsule is cylindrical as a whole, which is convenient for tight arrangement and installation and ensures that the capsule has good vertical pressure-bearing performance.

[0030] In this embodiment, the diameter of the end edge of the inner arc segment 4 is larger than its middle diameter, and the middle diameters of all inner arc segments 4 are the same, so that the connecting area between adjacent unit cavities 1 will not easily swing due to the small middle diameter of the inner arc segment 4, ensuring that the axis of the capsule body always remains vertically straight during expansion and contraction deformation, ensuring that the capsule body can effectively withstand vertical pressure and provide effective support for the user.

[0031] In this embodiment, the middle diameter of the outer arc segment 3 is A, the middle diameter of the inner arc segment 4 is B, 0.8≤B / A≤0.9, and the preferred solution is B / A=0.85. This ensures that the capsule has good resistance to vertical deformation by limiting the difference in the middle diameters of the outer arc segment 3 and the inner arc segment 4, thereby reducing the height change of the capsule when the hardness is adjusted. It also increases the difference in the middle diameters of the outer arc segment 3 and the inner arc segment 4 to increase the radial width of the vertical projection of the side wall of the capsule, thereby obtaining better resistance to radial deformation. It also increases the middle diameter of the inner arc segment 4 to improve the anti-bending performance of the capsule, thereby ensuring that the axis of the capsule always remains vertically straight. When B / A is less than 0.8, the top of the sac will easily swing due to the small diameter of the middle part of the inner arc segment 4, causing the axis of the sac to bend and unable to effectively withstand the vertical force; when B / A is greater than 0.9, the radial width of the vertical projection of the sac side wall is small, resulting in a decrease in the radial deformation resistance of the sac side wall, and the sac side wall is prone to radial expansion deformation during inflation, resulting in irreversible deformation of the sac.

[0032] Preferably, the vertical radial cross-sectional radius of the outer arc segment 3 is R1, and the vertical radial cross-sectional radius of the inner arc segment 4 is R2, and 0.16≤R2 / R1≤0.33. This ensures that the outer arc segment 3 has a larger diameter so that the outer arc segment 3 can be vertically straight in the region, and improves the vertical deformation resistance by reducing the number of unit cavities 1. It also ensures that the inner arc segment 4 can smoothly connect with the adjacent outer arc segments 3, and prevents excessive compression deformation when the capsule is deflated by eliminating creases. The vertical deformation resistance of the capsule is lowered by its own weight after deflation, effectively maintaining the capsule contour. When R2 / R1 is less than 0.16, the radius R2 of the inner arc segment 4 is small, and it is easy to bend due to concentrated force, which in turn increases the deformation amplitude of the capsule and affects the user experience; when R2 / R1 is greater than 0.33, the radius R1 of the outer arc segment 3 is small, resulting in a reduction in the radial width of the vertical projection of the capsule side wall, resulting in a reduction in the radial deformation resistance of the capsule.

[0033] Preferably, the radian angle of the vertical radial section of the outer arc segment 3 is C, 150°≤C≤170°, and the radian angle of the vertical radial section of the inner arc segment 4 is D, 130°≤D≤150°. By increasing the radian angle, the contour of the outer arc segment 3 on the vertical radial section tends to be linear, thereby effectively improving the resistance to vertical deformation.

[0034] The top of the bladder body is provided with a buffer cavity 5, the top wall of which forms a curved support surface 6. The buffer cavity 5 is connected to the bladder cavity, and the middle portion of the support surface 6 is raised upward. During use, the middle portion of the support surface 6 is compressed and deformed, increasing the contact area with the user. This not only ensures that the support surface 6 can match the user's surface through deformation, but also provides vertical support to the user through the bladder body, improving support comfort.

[0035] Example 2:

[0036] Compared with the first embodiment, this embodiment provides a support bladder.

[0037] As shown in the figure, the support cushion 8 comprises support airbags 2 and a base 7, with the airbags 2 mounted in a matrix arrangement on the base 7. The base 7 is provided with mounting holes arranged in a matrix, with the bottoms of the airbags 2 inserted into the corresponding mounting holes. This not only ensures that the airbags 2 maintain an upright position, but also positions the airbags 2, ensuring that adjacent airbags 2 are fixed relative to each other. The matrix arrangement of the airbags 2 ensures effective support for all areas of the user's body, thereby enhancing comfort.

[0038] In this embodiment, adjacent support airbags 2 are connected via air passages, ensuring that the air pressures in adjacent support airbags 2 can be adjusted synchronously, effectively simplifying the control system and facilitating operation.

[0039] The structure and effect of the support airbag described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0040] Example 3:

[0041] Compared with the second embodiment, this embodiment provides a mattress.

[0042] As shown in the figure, the mattress comprises the support cushion 8, a limiting pad 9 enclosing the support cushion 8, and an outer cover 10 including the support cushion 8 and the limiting pad 9. The limiting pad 9 holds, positions, and protects the support cushion 8, ensuring that the support airbags 2 on the support cushion 8 can be adjusted by inflation and deflation at a preset position. This not only ensures that the support cushion 8 can provide effective upward support and enhance comfort, but also effectively prevents interference between adjacent support cushions 8.

[0043] In this embodiment, the limiting pad 9 is provided with perforations, and the number and position of the perforations are matched one by one with the support airbags 2 on the support bag cushion 8. During installation, the limiting pad 9 wraps the support bag cushion 8, and the perforations are placed on the corresponding support airbags 2, so that each support airbag 2 is limited by the inner wall of the perforation, ensuring that the support airbag 2 can achieve vertical expansion and contraction under the guidance of the perforations, thereby generating vertical support for the user, providing the user with a comfortable support experience.

[0044] The structure and effect of the support bladder described in this embodiment are consistent with those in the second embodiment and will not be described in detail.
