The unit bag includes a plurality of unit cavities vertically stacked and interconnected, the air pressure in each unit cavity can be synchronously adjusted, and then the hardness of the unit bag is adjusted by lifting the air pressure. The outer peripheral wall of the existing air bag includes two vertically symmetrical inclined surfaces, which facilitates the stacking and contraction during deflation and facilitates the vertical expansion during inflation, so that the height of the air bag can be adjusted by inflation and deflation, and the air bag will be excessively contracted due to excessive deflation, which not only causes the top surface of the air bag cushion to be concave downward, affecting the appearance, but also causes the air bag to be unable to be accurately inflated and reset due to excessive concave deformation, shortening the service life of the air bag and affecting the use experience. SUMMARY

An inner corner part with a circular arc-shaped pressure-resistant surface is arranged at the joint of adjacent unit cavities, the angle of the inner corner part is effectively maintained, and then the unit bag always maintains a preset height after deflation, which not only ensures that the top surface of the air bag cushion remains flat, but also ensures that the unit bag can be quickly inflated and stretched and reset, improving the use experience. The inner corner part forms a pressure-resistant surface by being thickened, the inner corner part improves the anti-deformation performance by increasing the thickness, and then the inner corner part maintains a large included angle after the unit bag is deflated, and then the unit bag is effectively limited from collapsing and shrinking.

[0005] As preferred, the circular arc angle of the compression surface is A, 60°≤A≤110°, which not only increases the coverage area of the compression surface on the inner corner portion by increasing the circular arc angle of the compression surface, thereby ensuring that the inner corner portion has good deformation resistance, but also ensures that the corresponding end edges of adjacent unit cavities can be smoothly transferred through the compression surface.

[0006] As preferred, the ratio of the radius of the compression surface to the height of the unit cavity is B, 0.5≤B≤0.7, which not only ensures that the compression surface has a larger radius, thereby increasing the coverage area of the compression surface on the inner corner portion, but also ensures that the compression surface has bendability by limiting the radius of the compression surface, thereby reserving the stroke for the vertical expansion and contraction of the unit bladder.

[0007] As preferred, the inner side wall of the inner corner portion is triangular, and the thickness between the inner side wall of the inner corner portion and the compression surface is gradually changed, which disperses the force by the thickness gradient, prevents the inner corner portion from being easily bent and not reset due to local force concentration, and ensures the vertical reciprocating deformation of the unit bladder.

The two side edges of the outer corner portion are vertically symmetrically arranged, which not only ensures that the two side edges can tilt synchronously to the horizontal plane when subjected to vertical force, thereby ensuring that the force can be effectively transmitted downward, but also provides vertical deformation stroke for the unit bladder by opening and closing the two side edges, thereby meeting the hardness adjustment requirements.

[0010] As preferred, the included angle between the inner side wall of the outer corner portion and the inner corner portion is D, 100°≤D≤120°, which not only facilitates processing, but also ensures that the outer corner portion and the inner corner portion have balanced vertical deformation stroke, thereby facilitating the synchronous expansion and contraction deformation of each unit cavity.

[0011] As preferred, the unit bladder includes at least four unit cavities, and the vertical projections of the unit cavities coincide, which not only forms alternating inner corner portions and outer corner portions between the outer walls of the unit bladder, so that the unit cavities can realize vertical expansion and contraction in a horizontal posture, but also increases the number of inner corner portions and outer corner portions by increasing the number of unit cavities, thereby ensuring that the vertical expansion and contraction amplitude of the unit bladder meets the use requirements by accumulating the vertical deformation stroke of the inner corner portions and the outer corner portions, and also ensures that the corner portions can be reset accurately.

[0022] The essence of the utility model is further explained in combination with the drawings and specific embodiments of the specification.

[0023] Example one:

[0024] The embodiment provides an air bag cushion.

[0025] As Figure 1 And 2The airbag cushion shown comprises unit capsules 1 arranged in a matrix, the unit capsules 1 comprising unit cavities 2 vertically stacked and interconnected, the outer peripheral walls of adjacent unit cavities 2 being connected at the joint by inwardly recessing to form inner corner portions 3, the outer walls of the inner corner portions 3 being thickened by outwardly bulging to form compression-resistant surfaces 5 in the shape of circular arcs in vertical cross section, so that the unit capsules 1 maintain a preset height after deflation. The joint between adjacent unit cavities 2 is provided with the inner corner portions 3 with the circular-arc-shaped compression-resistant surfaces 5, effectively maintaining the angle of the inner corner portions 3, thereby ensuring that the unit capsules 1 always maintain the preset height after deflation, not only ensuring that the top surface of the airbag cushion 6 remains flat, but also ensuring that the unit capsules 1 can be quickly inflated and stretched to reset, improving the user experience.

[0026] In this embodiment, the corresponding end edges of the outer peripheral walls of adjacent unit cavities 2 are connected to form the inner corner portions 3, the middle portions of the outer peripheral walls of the unit cavities 2 are thickened by outwardly bulging to form outer corner portions 4, and the corresponding edges of adjacent compression-resistant surfaces 5 are formed into the outer corner portions 4 by tangentially extending and interlacing. The outer corner portions 4 and the inner corner portions 3 are vertically arranged alternately along the outer walls of the unit capsules 1 to provide guidance for the vertical stretching and contraction of the unit capsules 1. Specifically, the inner corner portions 3 are formed into circular-arc-shaped compression-resistant surfaces 5 by bulging, so that the inner corner portions 3 have good compression resistance, ensuring that the included angle parameter of the inner corner portions 3 is maintained at a relatively large value. The thickness of each region of the outer corner portions 4 is the same, and the outer corner portions 4 have greater deformation performance than the inner corner portions 3. When the unit capsules 1 deflate, the outer corner portions 4 will be driven to decrease the included angle due to the weight of the unit capsules 1, thereby assisting the unit capsules 1 to reduce the height. The inner corner portions 3 can effectively maintain the included angle under the support of the compression-resistant surfaces 5, thereby ensuring that the outer corner portions 4 on both sides maintain a relatively large vertical distance, effectively assisting the unit capsules 1 to maintain within the preset height range, and ensuring that the unit capsules 1 will not collapse due to excessive deflation. The use of the outer corner portions 4 and the inner corner portions 3 not only ensures that the vertical deformation amplitude of the unit capsules 1 meets the use requirements, but also ensures that the unit capsules 1 can adjust the height within the preset range.

[0027] In this embodiment, the circular-arc angle of the compression-resistant surfaces 5 is A, and 60°≤A≤110°. In a preferred embodiment, A=100°. By increasing the circular-arc angle of the compression-resistant surfaces 5 to increase the coverage area of the compression-resistant surfaces 5 on the inner corner portions 3, it is ensured that the inner corner portions 3 have good deformation resistance, and it is also ensured that the corresponding end edges of adjacent unit cavities 2 can smoothly overlap through the compression-resistant surfaces 5. In addition, the parameter A can also be 60°, 80°, 90°, 110°, etc., which should all be considered as specific embodiments of this embodiment.

[0028] In the embodiment, the ratio of the radius of the pressure-resistant surface 5 to the height of the unit cavity 2 is B, 0.5≤B≤0.7. Preferably, B=0.6, which ensures that the pressure-resistant surface 5 has a large radius, thereby increasing the coverage area of the pressure-resistant surface 5 on the inner corner portion 3, and also ensures that the pressure-resistant surface 5 is flexible by limiting the radius of the pressure-resistant surface 5, thereby reserving the stroke for the vertical expansion and contraction of the unit bladder 1. In addition, the parameter B can also be 0.5, 0.55, 0.65, 0.7, etc., which should all be considered as specific embodiments of the embodiment.

[0029] In the embodiment, the inner side wall of the inner corner portion 3 is triangular, the thickness between the inner side wall of the inner corner portion 3 and the pressure-resistant surface 5 is gradually changed, the inner corner portion 3 forms a top corner of a triangle, a waist edge with the same size is formed between the inner corner portion 3 and the adjacent outer corner portion 4, which ensures that the inner corner portion 3 can be symmetrically deformed after being stressed, and ensures that the unit bladder 1 can be expanded and contracted along the axial direction. The thickness between the pressure-resistant surface 5 and the inner side wall of the inner corner portion 3 is gradually changed, and the horizontal cross-sectional thickness of the inner corner portion 3 is C, 1mm≤C≤3mm, which ensures that the wall thickness of the inner corner portion 3 is the largest near the corner, effectively prevents the corner from being bent and deformed, thereby ensuring that the inner corner portion 3 can effectively maintain the original profile, and keeping the height of the unit bladder 1 within a predetermined range when it is deflated.

[0030] In the embodiment, the included angle between the outer corner portion 4 and the inner side wall of the inner corner portion 3 is D, 100°≤D≤120°. The included angle between the outer corner portion 4 and the inner corner portion 3 is the same, so that each segment of the unit bladder 1 has a balanced expansion and contraction range, effectively disperses the vertical deformation stroke of the unit bladder 1, prevents irreversible deformation of the unit bladder 1 due to local excessive expansion and contraction, and ensures that the unit bladder 1 can be used normally through inflation and deflation.

[0031] In the embodiment, the unit bladder 1 includes at least four unit cavities 2, and the vertical projections of the unit cavities 2 coincide. Preferably, five unit cavities 2 are stacked and connected to form the unit bladder 1, so that the unit bladder 1 has four outer corner portions 4 and three inner corner portions 3. By providing more inner corner portions 3, the height of the unit bladder 1 after deflation can meet the use requirements, by providing more outer corner portions 4, the vertical deformation range requirement of the unit bladder 1 is shared, and by reducing the vertical deformation stroke requirement of each outer corner portion 4, the unit bladder 1 can be accurately deformed.

[0032] In the embodiment, the unit bladders 1 are arranged in a matrix and spliced to form the airbag cushion 6 (as shown in Figure 3 The adjacent unit bladders 1 are connected and fixed through the air duct, and the inner cavities of the adjacent unit bladders 1 are connected through the air duct, so that the air pressure in the adjacent unit bladders 1 can be adjusted synchronously and the same softness and hardness can be obtained.

[0033] It can be understood that the outer corner part 4 can also be a round corner structure with an equal thickness wall surface (as shown in Figure 4 and 5 indicated), which can also play a role in limiting the vertical deformation of the unit capsule 1, and should also be considered as a specific embodiment of the present embodiment.

[0034] Embodiment Two:

[0035] Compared with Embodiment One, the present embodiment provides a mattress.

[0036] As shown in Figure 6 , a mattress includes a mattress body, which includes an air bag cushion 6 and a limiting block 7 clamping and wrapping the air bag cushion 6. The limiting block 7 plays a role in clamping, positioning and protecting the air bag cushion 6, ensuring that the air bag cushion 6 is adjusted in softness and hardness at a preset position by inflation and deflation, thereby improving the use comfort of the mattress body.

[0037] In the present embodiment, the limiting block 7 is provided with perforations, the number and position of which are matched with the unit capsules 1 on the air bag cushion 6 one by one. When installed, the limiting block 7 wraps the air bag cushion 6, and the perforations are sleeved on the corresponding unit capsules 1, so that each unit capsule 1 is limited by the inner wall of the perforation, ensuring that the unit capsule 1 realizes vertical expansion and contraction under the guidance of the perforation, and then adjusts the softness and hardness by adjusting the air pressure, thereby providing comfortable support for the user.

[0038] The other structures and effects of the air bag cushion in the present embodiment are consistent with those of Embodiment One, and will not be described again.
