[0026] The essence of the utility model is further explained in combination with the drawings and specific embodiments.

[0027] Embodiment one:

[0028] The embodiment provides a supporting air bag.

[0029] As shown in the supporting air bag shown in Figure 1 and 2 , comprising a cavity inside the bag body, the bag body is columnar, the outer wall of the bag body is provided with a reinforcing vertical rib 1 which is dispersedly arranged along the circumference direction thereof to limit the vertical collapse of the bag body when deflated. The bag body is cylindrical, the axis of the bag body is in a vertical state, the reinforcing vertical rib 1 is arranged on the outer wall of the bag body, the reinforcing vertical rib 1 plays a role of resisting axial deformation on the outer wall of the bag body, which can maintain the profile after deflation, effectively improve the axial compression resistance of the outer wall of the bag body, and also can limit the excessive axial expansion of the bag body when inflated, effectively improve the axial expansion resistance of the outer wall of the bag body, and improve the use experience.

[0030] In the embodiment, the reinforcing vertical rib 1 is vertically and linearly arranged on the outer wall of the bag body, the reinforcing vertical rib 1 is a plurality of reinforcing vertical ribs, and is equidistantly arranged along the circumferential direction of the outer wall of the bag body, so that each region of the outer wall of the bag body has balanced axial deformation resistance.

[0031] When inflated, the air pressure in the bag body rises and drives the vertical expansion of the bag body, the reinforcing vertical rib 1 can play a role of resisting axial expansion on the corresponding region of the outer wall of the bag body, prevent the irreversible vertical deformation of the outer wall of the bag body due to excessive air pressure in the bag body, not only protect the bag body, but also ensure that the top surface of the mattress will not be concave and convex due to the excessive bulging of the supporting air bag 7, and ensure the flatness of the top surface of the mattress. When deflated, the air pressure in the bag body decreases and drives the vertical contraction of the bag body, the reinforcing vertical rib 1 can play a role of resisting axial compression on the corresponding region of the outer wall of the bag body, prevent the vertical excessive contraction of the outer wall of the bag body, and further prevent the local collapse of the top surface of the mattress due to the excessive contraction of the supporting air bag 7, which can not only maintain the profile of the supporting bag body, but also effectively reduce the amount of air required when inflated again, thereby accelerating the air pressure regulation efficiency in the bag body, shortening the regulation time, reducing the operating power consumption and noise of the air pump.

[0032] In the embodiment, the two ends of the reinforcing vertical rib 1 are flush with the top edge and the bottom edge of the side wall of the bag body, the reinforcing vertical rib 1 vertically penetrates the outer wall of the bag body, so that each height section of the outer wall of the bag body can be connected in series by the same reinforcing vertical rib 1, and the circumferential regions of the outer wall of the bag body have balanced axial deformation resistance.

[0033] In the embodiment, the top surface and bottom surface edges of the reinforcing vertical ribs 1 are provided with round corners 2, and the top surface and bottom surface edges of the outer side wall of the capsule are provided with round corners 2, which effectively prevent wear and reduce the sense of foreign matter, and also ensure effective limiting of the outer side wall of the capsule.

[0034] In the embodiment, the horizontal section of the reinforcing vertical rib 1 is square (as shown in the figure), and the square section of the reinforcing vertical rib 1 has better structural strength and better tensile and compression resistance for the outer side wall of the capsule. Figure 3

[0035] In the embodiment, the reinforcing vertical ribs 1 are centrally symmetrically arranged around the axis of the capsule, and the reinforcing vertical ribs 1 are at least four. By increasing the number of reinforcing vertical ribs 1, the distance between adjacent reinforcing vertical ribs 1 is reduced, and the width of each area is reduced, so that each reinforcing vertical rib 1 can effectively limit and shape each corresponding area, thereby preventing the outer side wall of the capsule from bulging outward in the area between adjacent reinforcing vertical ribs 1, and ensuring that the height of the capsule is within the preset range.

[0036] In the embodiment, the reinforcing vertical rib 1 is formed by bulging outward from the outer side wall of the capsule. The capsule includes a vertically stacked cover 6 and a bottom plate, and the bottom plate covers the bottom surface of the cover 6 and encloses and blocks to form the capsule cavity. The reinforcing vertical rib 1 and the cover 6 are integrally processed and formed, ensuring that they are firmly connected and improving the axial deformation resistance of the cover 6. The bottom plate is integrally processed and formed, and when installed, the cover 6 is covered on the bottom plate and is firmly connected by welding to form the capsule with the cover 6 and the bottom plate, which is convenient for processing, reduces the workload, and also improves the sealing reliability by reducing the welding area.

[0037] In the embodiment, the top of the capsule is provided with a buffer cavity 3 connected with the capsule cavity. The top of the buffer cavity 3 is provided with a circular arc-shaped supporting surface 4, and the middle part of the supporting surface 4 bulges upward. In use, the middle part of the supporting surface 4 is deformed under pressure and increases the contact area with the user, which ensures that the supporting surface 4 can be matched and fitted with the surface of the user by deformation, and also can use the capsule to vertically support the user to improve the support comfort.

[0038] In the embodiment, the bottom periphery of the buffer cavity 3 is formed into a ring-shaped deformation groove 5 by radially inwardly recessing. The deformation groove 5 is arranged to form a reduced diameter structure at the joint of the buffer cavity 3 and the top of the capsule, which facilitates the swinging and rotation of the buffer cavity 3 by reducing the diameter of the joint, and ensures that the supporting surface 4 can be fitted with the surface of the user.

[0039] Embodiment Two:

[0040] Compared with Embodiment One, the present embodiment provides a support capsule.

[0041] As​Figure 4 The support pad shown includes the support airbags 7, which are arranged in a matrix and connected to adjacent airbags via air passages. The matrix arrangement of the support airbags 7 ensures effective support for all areas of the user's surface, thereby improving support comfort.

[0042] In this embodiment, adjacent support airbags 7 are connected by air passages to ensure that the air pressure inside adjacent support airbags 7 can be adjusted synchronously. This not only simplifies the control system and makes it easy to operate, but also ensures that the relative positions between adjacent support airbags 7 remain fixed.

[0043] The structure and effect of the supporting airbag described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0044] Example 3:

[0045] Compared to Embodiment 2, this embodiment provides a mattress.

[0046] like Figure 5 The mattress shown includes the support cushion 8, a limiting pad 9 that surrounds the support cushion 8, and an outer cover 10 that surrounds the support cushion 8 and the limiting pad 9. The limiting pad 9 serves to clamp, position, and protect the support cushion 8, ensuring that the support airbags 7 on the support cushion 8 are adjusted in a preset position by inflation and deflation. This ensures that the support cushion 8 can provide effective upward support, improving support comfort, and also effectively prevents interference between adjacent support cushions 8.

[0047] In this embodiment, the limiting pad 9 is provided with perforations. The number and position of the perforations are matched one by one with the support airbags 7 on the support pad 8. During installation, the limiting pad 9 wraps around the support pad 8, and the perforations are fitted onto the corresponding support airbags 7, so that each support airbag 7 is limited by the inner wall of the perforation, ensuring that the support airbag 7 can achieve vertical expansion and contraction under the guidance of the perforation, thereby providing vertical support to the user and providing a comfortable support experience for the user.

[0048] The structure and effect of the support pad described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
