Description

Technical Field

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

[0002] Existing mattresses include airbag cushions, which comprise airbag strips tightly arranged in a front-to-back direction. These strips are provided with linearly arranged unit cells. Adjacent unit cells are connected by air passages, allowing for synchronous regulation of the air pressure within each unit cell. This allows for synchronized regulation of the air pressure within adjacent airbag strips when they are interconnected. During installation, front and rear connecting pieces are provided on the long edges of the strips. Adjacent airbag strips are aligned side by side and welded together using the corresponding front and rear connecting pieces. Because these strips lack alignment marks, the spacing between adjacent airbag strips may not meet requirements or may be non-parallel due to misalignment. This can result in the unit cells not being distributed as desired, impacting the user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides an airbag cushion and a mattress using the same. Front holes and rear holes are respectively provided on the front connecting piece and the rear connecting piece. The front holes and the rear holes are vertically aligned and ensure that the front connecting piece and the rear connecting piece are precisely stacked and fixed, thereby ensuring that the relative positions of adjacent airbag strips are fixed and meet the usage requirements, thereby improving the user experience.

[0004] The utility model is realized in the following manner: an airbag cushion comprises a cushion body, the cushion body comprising airbag strips arranged in parallel along its front-to-back direction, the front edges and rear edges of adjacent airbag strips being respectively provided with front connecting pieces with front holes and rear connecting pieces with rear holes, and when the front connecting pieces and rear connecting pieces of adjacent airbag strips are stacked and fixedly connected, the front holes and the corresponding rear holes are vertically aligned, so that the adjacent airbag strips are arranged parallel and equidistant. The front holes and rear holes are respectively provided on the front connecting piece and the rear connecting piece, the front holes and the rear holes are vertically aligned and ensure that the front connecting piece and the rear connecting piece are precisely stacked and fixedly connected, thereby ensuring that the adjacent airbag strips are parallel to each other and that the distance between the adjacent airbag strips meets the use requirements, providing comfortable support for the user and improving the use experience.

[0005] Preferably, the corresponding front and rear connecting pieces of adjacent airbag strips are provided with corresponding front and rear holes. This one-to-one correspondence between the front and rear holes not only facilitates alignment when the airbag strips are assembled, but also effectively improves assembly efficiency and ensures that the relative positions of adjacent airbag strips are uniquely fixed.

[0006] Preferably, the front hole and the rear hole are both circular and have the same diameter, which not only facilitates the coaxial arrangement of the front hole and the rear hole by aligning the periphery, but also facilitates punching processing.

[0007] Preferably, the front holes are arranged in the area where the front connecting piece is covered by the rear connecting piece, and the rear holes are arranged in the area where the rear connecting piece is covered by the front connecting piece. The peripheries of the front holes and the rear holes are overlapped and welded to ensure that the front connecting piece and the rear connecting piece are firmly connected.

[0008] Preferably, the front connecting piece is provided with at least two separate front holes, and the rear connecting piece is provided with at least two separate rear holes, which not only facilitates processing and alignment operations by limiting the number of front holes and rear holes, but also prevents the front connecting piece and the rear connecting piece from being offset or deflected from each other by synchronously aligning multiple front holes and rear holes, thereby ensuring that the relative positions of adjacent airbag strips are fixed.

[0009] Preferably, at least two dispersed front connecting pieces are provided at the leading edge of the airbag strip, and at least two dispersed rear connecting pieces are provided at the trailing edge of the airbag strip. This not only facilitates processing by limiting the number of front connecting pieces and rear connecting pieces, but also ensures that the distances between corresponding sections of adjacent airbag strips are the same by providing multiple front connecting pieces and rear connecting pieces, thereby ensuring that the relative positions are fixed and preventing deflection or offset.

[0010] Preferably, the airbag strip comprises upper and lower panels that are stacked, adhesively bonded, and are provided with the front and rear connecting panels on their facing surfaces, respectively, to form highly offset front and rear connecting panels between adjacent airbag strips. Both the upper and lower panels are independently and integrally formed, facilitating large-scale, independent processing and improving production efficiency. They also facilitate stacking and welding to form the airbag strip, improving assembly efficiency. The upper and lower panels share the same structural profile, allowing them to share production equipment, effectively improving processing efficiency and reducing costs.

[0011] Preferably, the upper and lower bladder panels are both elongated and each is provided with a plurality of linearly arranged bladder cavities. The bladder cavities on the upper and lower bladder panels overlap and enclose a unit bladder that can be vertically expanded and deformed, ensuring that the unit bladder can provide stable support for the user through vertical expansion.

[0012] Preferably, the sidewall of the capsule cavity is provided with an annular inner corner and an annular outer corner formed by alternating radial concavities and convexities from top to bottom, and the inner corner and outer corner guide the vertical expansion and contraction of the capsule cavity by opening and closing. The inner corner and outer corner are vertically alternately arranged on the outer sidewall of the capsule cavity to ensure that the outer sidewall of the capsule cavity can bend along the inner corner and outer corner and achieve vertical expansion and contraction, which not only plays the role of guiding the capsule cavity to deform in a preset direction, but also ensures that the vertical deformation amplitude of the capsule cavity meets the use requirements. The capsule cavities disposed on the upper capsule plate and the lower capsule plate cooperate with each other to ensure that the unit capsule can vertically expand and contract and deform precisely.

[0013] A mattress includes the airbag cushion, which provides comfortable support for the user and thus improves the user experience.

[0014] The beneficial effects of the present invention are as follows: a front hole and a rear hole are respectively provided on the front connecting piece and the rear connecting piece, the front hole and the rear hole are vertically aligned and ensure that the front connecting piece and the rear connecting piece are accurately overlapped and fixed, which not only ensures that adjacent airbag strips are parallel to each other, but also ensures that the distance between adjacent airbag strips meets the use requirements, provides comfortable support for users, and enhances the use experience.

[0019] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0020] Example 1:

[0021] This embodiment provides an airbag cushion.

[0022] like Figure 1The illustrated airbag cushion includes a cushion body comprising airbag strips 1 arranged side by side along its front-to-back direction. The front and rear edges of adjacent airbag strips 1 are respectively provided with a front connecting piece 2 with a front hole 4 and a rear connecting piece 3 with a rear hole 5. When the front connecting pieces 2 and rear connecting pieces 3 of adjacent airbag strips 1 are stacked and fixed together, the front holes 4 and the corresponding rear holes 5 are vertically aligned, so that adjacent airbag strips 1 are arranged parallel and equidistant. The front holes 4 and rear holes 5 are respectively provided on the front connecting piece 2 and the rear connecting piece 3. The front holes 4 and rear holes 5 are vertically aligned and ensure that the front connecting piece 2 and the rear connecting piece 3 are precisely stacked and fixed together, ensuring that adjacent airbag strips 1 are parallel to each other and that the distance between adjacent airbag strips 1 meets usage requirements, providing comfortable support for the user and enhancing the user experience.

[0023] In this embodiment, the corresponding front connecting pieces 2 and rear connecting pieces 3 of the adjacent airbag strips 1 are provided with corresponding front holes 4 and rear holes 5 (eg Figure 2 The front edge of the airbag strip 1 is provided with three equidistant front connecting pieces 2, and the rear edge is provided with three equidistant rear connecting pieces 3. The outer end of the front connecting piece 2 is provided with two separate front holes 4, and the outer end of the rear connecting piece 3 is provided with two separate rear holes 5. During installation, the two airbag strips 1 are parallel to each other and docked through the corresponding front connecting pieces 2 and rear connecting pieces 3. During docking, the front holes 4 on the three front connecting pieces 2 are coaxially aligned with the corresponding rear holes 5 on the three rear connecting pieces 3 (as shown). Figure 3 As shown), an overlapping area is formed between the corresponding front connecting piece 2 and the rear connecting piece 3. The welding area is formed by welding the overlapping area, which ensures that the corresponding front connecting piece 2 and the rear connecting piece 3 are fixed to each other and positioned, and ensures that the relative positions of adjacent airbag strips 1 are fixed and maintained in relative positions that are parallel to each other and the spacing meets the preset requirements. It also facilitates assembly operations for assemblers and reduces the number of waste products caused by unsatisfactory fixing accuracy.

[0024] In this embodiment, the front holes 4 and rear holes 5 are both circular and have the same diameter. The aligned front holes 4 and rear holes 5 are maintained coaxially by inserting a latch, thereby ensuring that the relative position of adjacent airbag ribs 1 is fixed and prevents displacement during welding, thereby improving assembly efficiency and accuracy. After the adjacent airbag ribs 1 are secured, the latch is removed for easy reuse.

[0025] In this embodiment, the front hole 4 is arranged on the area where the front connecting piece 2 is covered by the rear connecting piece 3, and the rear hole 5 is arranged on the area where the rear connecting piece 3 is covered by the front connecting piece 2, ensuring that the front connecting piece 2 and the rear connecting piece 3 can be overlapped and welded through the area located at the periphery of the front hole 4 and the rear hole 5, thereby improving the connection firmness by increasing the welding area and effectively utilizing the extended ends of the front connecting piece 2 and the rear connecting piece 3, achieving the effects of precise alignment and firm assembly.

[0026] In this embodiment, the front connecting piece 2 is provided with at least two separate front holes 4, and the rear connecting piece 3 is provided with at least two separate rear holes 5. The front holes 4 are provided on both sides of the outer edge of the front connecting piece 2, and the rear holes 5 are provided on both sides of the outer edge of the rear connecting piece 3. By increasing the distance between the front holes 4 and the rear holes 5, the alignment accuracy is improved to prevent deflection and offset.

[0027] In this embodiment, at least two dispersed front connecting pieces 2 are provided at the leading edge of the airbag strip 1, and at least two dispersed rear connecting pieces 3 are provided at the trailing edge of the airbag strip 1. The number of the front connecting pieces 2 and rear connecting pieces 3 can be increased or decreased according to the length of the airbag strip 1, ensuring that corresponding sections of adjacent airbag strips 1 can be positioned and fixedly connected by the corresponding front connecting pieces 2 and rear connecting pieces 3.

[0028] In this embodiment, the airbag strip 1 comprises an upper bladder panel 6 and a lower bladder panel 7 that are stacked and adhesively bonded. The front and rear connecting panels 2 and 3 are disposed on the facing surfaces of the upper and lower bladder panels 6, 7, respectively, to form highly offset front and rear connecting panels 2 and 3 between adjacent airbag strips 1. Both the upper and lower bladder panels 6, 7 are elongated and each is provided with a plurality of linearly arranged bladder cavities 8. The upper and lower bladder panels 6, 7 are independently machined and welded together to form the airbag strip 1. The upper bladder panel 6 has the front connecting panels 2 symmetrically arranged along its length, while the lower bladder panel 7 has the rear connecting panels 3 symmetrically arranged along its length. This ensures that the upper and lower bladder panels 6, 7 share a common structural profile, facilitating shared production equipment and molds for batch processing, reducing equipment costs and improving processing and assembly efficiency.

[0029] In this embodiment, the front connecting piece 2 and the rear connecting piece 3 are respectively arranged on the upper bag plate 6 and the lower bag plate 7, so that there is a height difference between the front connecting piece 2 and the rear connecting piece 3, ensuring that the adjacent upper bag plates 6 and the adjacent lower bag plates 7 are kept at the same height after the front connecting piece 2 and the rear connecting piece 3 are overlapped, thereby ensuring that the top and bottom surfaces of adjacent unit bags are flush.

[0030] In this embodiment, the sidewall of the capsule cavity 8 is provided with an annular inner corner 9 and an annular outer corner 10 formed by alternating radial concavities and convexities from top to bottom. The inner corner 9 and the outer corner 10 guide the capsule cavity 8 to expand and contract vertically by opening and closing. The inner corner 9 and the outer corner 10 are vertically alternately arranged on the outer sidewall of the capsule cavity 8 to ensure that the outer sidewall of the capsule cavity 8 can bend along the inner corner 9 and the outer corner 10 and achieve vertical expansion and contraction, which not only guides the capsule cavity 8 to deform in a preset direction, but also ensures that the vertical deformation amplitude of the capsule cavity 8 meets the requirements of use. The inner corner 9 and the outer corner 10 guide the capsule cavity 8 to expand and contract vertically by opening and closing, ensuring that the capsule cavity 8 can be precisely deformed.

[0031] Example 2:

[0032] Compared with the first embodiment, this embodiment provides a mattress.

[0033] The mattress includes an airbag cushion and a stopper that clamps and wraps the airbag cushion. The stopper holds, positions, and protects the airbag cushion, ensuring that the airbag cushion is adjusted in a preset position by inflating and deflating air, thereby improving the comfort of the mattress.

[0034] In this embodiment, the corresponding cavities 8 on the upper bag plate 6 and the lower bag plate 7 are stacked to form a vertically retractable unit bag. The limit block is provided with perforations, and the number and position of the perforations are matched one by one with the unit bags on the airbag cushion. During installation, the limit block wraps the airbag cushion, and the perforations are placed on the corresponding unit bags, so that each unit bag is limited by the inner wall of the perforation, ensuring that the unit bag can achieve vertical expansion and contraction under the guidance of the perforations, and then the hardness can be adjusted by adjusting the air pressure to provide comfortable support for the user.

[0035] The other structures and effects of the airbag cushion described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
