Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a support airbag, a support pad, and a mattress. Background Technology

[0002] Existing mattresses include a support cushion pad, which comprises closely arranged support airbags connected by air channels. This allows the airbags on the support cushion to adjust their air pressure synchronously, thereby ensuring adjustable firmness. Existing support airbags include a cylindrical body with an internal cavity and a smooth, flat outer wall. During inflation, the middle of the outer wall of the body may expand radially due to the lack of a restraining structure. This radial expansion prevents the airbag from providing effective upward support, thus reducing its support performance and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a support airbag, a support pad, and a mattress. A ring-shaped reinforcing rib is provided on the outer wall of the airbag, which restricts radial expansion of the airbag, thereby ensuring good vertical support performance and improving lying comfort.

[0004] This utility model is achieved through the following method: a support airbag includes an airbag body with an internal cavity. The airbag body is cylindrical, and the outer wall of the airbag body is provided with annular reinforcing ribs arranged around its circumference to limit the radial expansion of the airbag body during inflation. The annular reinforcing ribs on the outer wall of the airbag body limit the radial expansion of the airbag body, ensuring that the airbag body can vertically elongate during inflation, thereby ensuring good vertical support performance and improving lying comfort. It also ensures that adjacent airbag bodies do not interfere with each other, preventing collisions and protecting the airbag body. Furthermore, it ensures that the axis of the airbag body always remains vertical, ensuring good vertical support performance.

[0005] Preferably, the reinforcing ribs are multiple and staggered at equal intervals along the axis of the capsule. The reinforcing ribs are positioned on various height sections of the outer wall of the capsule, ensuring that each section of the outer wall has good resistance to radial expansion.

[0006] Preferably, the single reinforcing rib is horizontally arranged. The reinforcing rib is arranged in a horizontal ring shape, which ensures that each section of the outer wall of the capsule can obtain good resistance to radial expansion, and also facilitates processing.

[0007] Preferably, there are at least three reinforcing ribs. This not only reduces the distance between adjacent reinforcing ribs by increasing the number of reinforcing ribs, thereby improving the radial expansion resistance of each section, but also simplifies the structure by limiting the number of reinforcing ribs, making processing and production easier.

[0008] Preferably, the reinforcing rib has a square cross-sectional profile, with rounded corners at each corner. The square cross-section of the reinforcing rib provides better tensile strength, thereby improving the radial expansion resistance of the outer wall of the bladder. The rounded corners at the cross-sectional angles facilitate processing and effectively disperse forces, preventing damage caused by friction between adjacent reinforcing ribs.

[0009] Preferably, the reinforcing rib is formed by an outward bulge from the outer wall of the bladder. The reinforcing rib and the bladder are integrally formed, which facilitates mass production and ensures a firm connection between the reinforcing rib and the bladder, effectively improving the radial expansion resistance of the bladder sidewall.

[0010] Preferably, the top of the bladder body is provided with a buffer cavity communicating with the bladder cavity. The top wall of the buffer cavity bulges upward in the middle, so that the top of the bladder body can be compressed and buffered through the buffer cavity, thereby providing comfortable support for the user.

[0011] Preferably, the top of the buffer cavity is provided with an arc-shaped support surface, and the middle part of the buffer cavity is easy to deform due to its small contact area with the user, thereby matching and fitting the user's surface and improving support comfort.

[0012] Preferably, the bottom periphery of the buffer cavity is radially recessed to form an annular deformation groove. This groove not only creates space for the buffer cavity to swing, allowing the top wall of the buffer cavity to match and fit the user's surface through swinging, but also reduces the resistance during swinging by decreasing the diameter at the connection between the buffer cavity and the top edge of the outer wall of the bladder, thus improving the swinging flexibility.

[0013] Preferably, the capsule comprises a cover and a base plate that are vertically stacked and fixed together. The base plate covers the bottom surface of the cover and encloses and seals the capsule cavity. Both the cover and the base plate are independently and integrally formed. The cover is stacked on the base plate and fixed together by welding to ensure that the capsule cavity inside the capsule is isolated from the external space, facilitating air pressure adjustment.

[0014] A support pad includes the support airbags arranged in a matrix, with adjacent airbags connected by air channels. The matrix arrangement of the airbags ensures effective support for all areas of the user's surface. The interconnected air channels between adjacent airbags allow for synchronized adjustment of air pressure within each airbag, thereby controlling the synchronous adjustment of firmness and softness to enhance the user experience.

[0015] A mattress includes a support cushion, a positioning pad enclosing the support cushion, and an outer cover enclosing the support cushion and the positioning pad. The positioning pad clamps, positions, and protects the support cushion, ensuring that the support cushion is in a preset position and its firmness can be adjusted by inflation and deflation, thereby improving the mattress's comfort. The outer cover encloses the support cushion and the positioning pad, providing positioning and protection for them.

[0016] The beneficial effects of this utility model are as follows: A ring-shaped reinforcing rib is provided on the outer wall of the bladder. This rib restricts the radial expansion of the bladder, ensuring that it can vertically elongate when inflated, thus providing good vertical support and improving lying comfort. It also ensures that adjacent bladders do not interfere with each other, preventing collisions and protecting the bladder. Furthermore, it ensures that the axis of the bladder remains vertical, guaranteeing good vertical support. Attached Figure Description

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] This embodiment provides a support airbag.

[0028] like Figure 1 , 2 The support airbag shown in Figure 3 includes an airbag body with an internal cavity. The airbag body is cylindrical, and the outer wall of the airbag body is provided with annular reinforcing ribs 1 arranged around its circumference to limit the radial expansion of the airbag body during inflation. The annular reinforcing ribs 1 on the outer wall of the airbag body restrict the radial expansion of the airbag body, ensuring that the airbag body can vertically elongate during inflation, thereby ensuring good vertical support performance and improving lying comfort. It also ensures that adjacent airbag bodies do not interfere with each other, preventing collisions and protecting the airbag body. Furthermore, it ensures that the axis of the airbag body always remains vertical, ensuring good vertical support performance.

[0029] In this embodiment, the reinforcing rib 1 is annular and surrounds the outer wall of the bladder. Specifically, there are multiple reinforcing ribs 1, which are staggered and equidistantly distributed along the axial direction of the bladder. The bladder is divided into multiple sections along its axial direction, and each section has a corresponding reinforcing rib 1 on its outer wall. The reinforcing ribs 1 limit the outer wall of each section, ensuring that the outer wall of the bladder will not expand radially due to the increase in air pressure. This ensures that the bladder can vertically elongate when inflated, and the vertical support performance of the bladder is improved by increasing the distance between the top and bottom walls of the bladder, providing effective support for the user.

[0030] In this embodiment, a single reinforcing rib 1 is horizontally arranged, and each reinforcing rib 1 is arranged in the same horizontal plane. The reinforcing rib 1 is arranged along the centerline of the outer wall of the corresponding section, and the distance between adjacent reinforcing ribs 1 is the same, so as to ensure that the outer wall of each section of the bladder has balanced anti-radial expansion performance.

[0031] In this embodiment, there are at least three reinforcing ribs 1. By increasing the number of reinforcing ribs 1, the distance between adjacent reinforcing ribs 1 is reduced, thereby reducing the width of the outer wall of each section. This ensures that each reinforcing rib 1 can effectively limit and shape each section, thereby preventing the outer wall of the bladder from bulging outward in the area between adjacent reinforcing ribs 1, and ensuring that the bladder maintains a cylindrical outline.

[0032] In this embodiment, the reinforcing rib 1 has a square cross-sectional profile, and rounded corners 2 are provided at each corner of the cross-sectional profile of the reinforcing rib 1. The square cross-section of the reinforcing rib 1 has good structural strength and plays a good role in limiting the outer wall of the bladder. The rounded edges of the reinforcing rib 1 effectively prevent wear and loss of the reinforcing rib 1, thereby preventing the structural strength of the reinforcing rib 1 from being uneven due to local loss, ensuring that each segment of the reinforcing rib 1 has balanced tensile strength in the circumferential direction, and thus ensuring that the bladder profile remains constant.

[0033] In this embodiment, the reinforcing rib 1 is formed by an outward bulge from the outer wall of the bladder. The bladder includes a vertically stacked and fixed cover 6 and a base plate. The base plate covers the bottom surface of the cover 6 and encloses and seals the bladder cavity. The reinforcing rib 1 and the cover 6 are integrally formed, ensuring a firm connection between the two and improving the radial deformation resistance of the cover 6. The base plate is integrally formed. During installation, the cover 6 is placed on the base plate and fixed by welding, so that the cover 6 and the base plate enclose the bladder to form the bladder. This facilitates processing, reduces workload, and improves sealing reliability by reducing the welding area.

[0034] In this embodiment, the top of the bladder body is provided with a buffer cavity 3 that communicates with the bladder cavity. The top of the buffer cavity 3 is provided with an arc-shaped support surface 4, the middle of which is raised upward. During use, the middle of the support surface 4 is deformed under pressure, increasing the contact area with the user. This ensures that the support surface 4 can fit and conform to the user's surface through deformation, and also provides vertical support to the user using the bladder body, improving support comfort.

[0035] Understandably, the bottom periphery of the buffer cavity 3 is radially recessed to form an annular deformation groove 5 (e.g., Figure 4 and 5 As shown, by setting the deformation groove 5, a reduced diameter structure is formed at the connection between the buffer cavity 3 and the top of the bladder. By reducing the diameter of the connection, the buffer cavity 3 can swing and rotate, ensuring that the supporting surface 4 can fit with the user's surface. This should also be regarded as a specific implementation of this embodiment.

[0036] Example 2:

[0037] Compared to Embodiment 1, this embodiment provides a support pad.

[0038] like Figure 6 The support pad 8 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.

[0039] 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.

[0040] 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.

[0041] Example 3:

[0042] Compared to Embodiment 2, this embodiment provides a mattress.

[0043] like Figure 7 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.

[0044] 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.

[0045] 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.
