Description

Technical Field

[0001] This application relates to the field of mattresses, and in particular to an airbag device and a mattress. Background Technology

[0002] Airbag mattresses, as a new type of sleep support device, are typically composed of closely arranged airbags. The internal airbags (air springs) have equal top and bottom surfaces to ensure a flat mattress surface for even support. Adjacent airbags communicate with each other via connecting tubing, forming a dynamic air pressure regulation system that allows for adjustable mattress firmness.

[0003] However, in practical applications, it has been found that the connecting pipes are prone to deformation when subjected to radial compression or bending stress, which leads to a significant reduction in the effective flow cross-sectional area inside the pipe, resulting in problems such as decreased gas flow efficiency and delayed air pressure balance. This directly affects the mattress's ability to respond quickly to changes in the user's body pressure and its overall support stability.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned issues, this application provides an airbag device and mattress to maintain an effective flow cross-sectional area within the connecting pipes.

[0006] This application provides an airbag device, including two airbags, and the chambers in the two airbags are connected by a connecting pipe.

[0007] The airbag device also includes:

[0008] A support member is disposed within the connecting pipe and extends along the length of the connecting pipe;

[0009] The supporting member is configured to maintain an effective flow cross-sectional area within the connecting pipe when the connecting pipe is subjected to radial pressure.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0017] Optionally, the sound-absorbing component is sound-absorbing cotton.

[0018] Optionally, the connecting pipe has a receiving cavity for accommodating the silencing component.

[0019] Optionally, the support member includes two sets of support ribs, which are located on both sides of the receiving cavity.

[0020] Optionally, the airbag device includes:

[0021] A first half-shell, having a first half-cavity, wherein the opening of the first half-cavity has a first end face; and

[0022] The second half-shell has a second half-cavity, and the opening of the second half-cavity has a second end face;

[0023] The first end face is welded to the second end face so that the first half cavity and the second half cavity form the chamber and the connecting pipeline.

[0024] Optionally, the airbag is a gas spring;

[0025] The sidewall of the airbag includes an annular corrugated structure that guides the expansion and contraction of the airbag.

[0026] This application discloses an airbag device and mattress. By providing a support member extending along the length of the connecting pipe inside the connecting pipe, the deformation of the connecting pipe under radial pressure is effectively suppressed, ensuring the stable maintenance of the effective flow cross-sectional area inside the connecting pipe, and significantly improving the air pressure balance response speed and dynamic support stability of the airbag device.

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] like Figures 1 to 5As shown, this application provides an airbag device 100, including two airbags 10, the chambers 12 in the two airbags 10 are connected by a connecting pipe 20; the airbag device 100 also includes a support member 30, which is disposed in the connecting pipe 20 and extends along the length of the connecting pipe 20; wherein, the support member 30 is configured to maintain the effective flow cross-sectional area in the connecting pipe 20 when the connecting pipe 20 is subjected to radial pressure.

[0045] By providing a support member 30 extending along the length of the connecting pipe 20 within the connecting pipe 20, the deformation of the connecting pipe 20 under radial pressure is effectively suppressed, ensuring the stable maintenance of the effective flow cross-sectional area within the connecting pipe 20, and significantly improving the air pressure balance response speed and dynamic support stability of the airbag device 100.

[0046] In this embodiment, as Figures 1 to 2 As shown, the number of airbags 10 in the airbag device 100 is not strictly limited; the airbags 10 in the airbag device 100 are arranged along a first direction so that the airbag device 100 has a length direction that is parallel to the first direction in space. The length direction of the connecting pipe 20 is approximately parallel to the length direction of the airbag device 100.

[0047] In this embodiment, as Figures 1 to 3 As shown, the airbag device 100 also includes an air inlet 101, which is connected to an external air source so that the external air source can inflate and deflate the airbag device 100. The airbag device 100 also has an air intake chamber 102 that is connected to both the air inlet 101 and the chamber 12; the air inlet 101 is located at the end of the airbag device 100; the air inlet 101 is connected to an external air source through a pipe. The external air source can be an air pump.

[0048] In this embodiment, as Figures 1 to 5 As shown, the airbag device 100 also includes connecting ears 50; two airbag devices 100 arranged side by side along a length direction perpendicular to the airbag device 100 are connected by connecting ears 50. Each airbag 10 has two connecting ears 50, which are located on both sides of the airbag 10. The connecting ears 50 have positioning holes, which facilitate the connection of the connecting ears in the two airbag devices 100 arranged side by side.

[0049] In this embodiment, as Figures 1 to 5As shown, the airbag device 100 includes a first half-shell 60 and a second half-shell 70. The first half-shell 60 has a first half-cavity 61, and the opening of the first half-cavity 61 has a first end face 62. The second half-shell 70 has a second half-cavity 71, and the opening of the second half-cavity 71 has a second end face 72. The first end face 62 and the second end face 72 are welded together to form a chamber 12 and a connecting pipe 20. By welding the first half-shell 60 and the second half-shell 70, the chamber 12 and the connecting pipe 20 can be formed, thereby reducing the number of welding points in the airbag device 100 and reducing the leakage points generated during welding, thus reducing the manufacturing difficulty of the airbag device 100.

[0050] In this embodiment, as Figures 3 to 5 As shown, both the first end face 62 and the second end face 72 are flat annular welding surfaces. When processing the airbag device 100, the first end face 62 and the second end face 72 are welded together to fix each other, reducing the leakage points during welding, which can reduce the processing difficulty of the airbag device 100 and extend the service life of the airbag device 100.

[0051] In this embodiment, as Figures 3 to 5 As shown, the airbag device 100 has a height direction in space, which is perpendicular to the length direction. The first half-shell 60 and the second half-shell 70 are arranged along the height direction of the airbag device 100; that is, the first half-shell 60 is located above the second half-shell 70, and the first end face 62 and the second end face 72 are located in the middle position of the airbag device 100.

[0052] In this embodiment, as Figures 1 to 5 As shown, the airbag 10 is a gas spring; the structure of the gas spring can adopt existing technology; for example, the sidewall of the airbag 10 includes an annular corrugated structure 11, which can guide the expansion and contraction deformation of the airbag 10. The annular corrugated structure 11 is composed of multiple periodically arranged peaks and troughs, and the cross-section of the annular corrugated structure 11 is corrugated.

[0053] In this embodiment, as Figures 3 to 5 As shown, the support member 30 includes a support rib 31, which is attached to the inner wall of the connecting pipe 20 so that the position of the support rib 31 relative to the connecting pipe 20 is fixed. The support rib 31 extends along the length of the connecting pipe 20.

[0054] In this embodiment, as Figures 3 to 5 As shown, the number of support ribs 31 can be 1, 2, 3 or more; when the number of support ribs 31 is 2 or more, the support ribs 31 are arranged around the circumference of the connecting pipe 20.

[0055] In this embodiment, as Figures 3 to 5 As shown, there are two support ribs 31, which are respectively disposed on the first half-shell 60 and the second half-shell 70. The two support ribs 31 are arranged in the radial direction of the connecting pipe 20, and there is a gap between the two support ribs 31, so as to reduce the effective flow cross-sectional area occupied by the support ribs 31 in the connecting pipe 20.

[0056] In this embodiment, as Figures 3 to 5 As shown, the support rib 31 protrudes outward from the inner wall of the connecting pipe 20. When the connecting pipe 20 is flattened and deformed due to radial pressure, a flow channel is formed between the two sides of the rib 31 and the inner wall of the pipe to maintain gas flow. The support rib 31 is integrally formed with the inner wall of the connecting pipe 20, which can reduce the processing of the support rib 31 and the connecting pipe 20, and strengthen the connection strength between the support rib 31 and the connecting pipe 20.

[0057] In this embodiment, as Figure 3 As shown, the airbag device 100 also includes a noise-reducing component 40 disposed within the connecting pipe 20; noise is generated when gas passes through the connecting pipe 20, and the noise can be reduced by the noise-reducing component 40. The noise-reducing component 40 can adopt existing technology; for example, the noise-reducing component 40 is sound-absorbing cotton.

[0058] In this embodiment, as Figure 3 As shown, the connecting pipe 20 has a receiving cavity 21 for accommodating the silencing component 40, which facilitates the assembly of the silencing component 40. The middle position of the connecting pipe 20 is enlarged to form the receiving cavity 21 to facilitate the processing of the receiving cavity 21. The supporting component 30 includes two sets of supporting ribs 31, which are located on both sides of the receiving cavity 21.

[0059] like Figures 1 to 5 As shown, this application also provides a mattress, including the airbag device 100 as described in the above embodiments. When the airbag device 100 is disposed on the mattress, there are multiple airbag devices 100, which are arranged side by side along the width or length direction of the mattress.

[0060] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0061] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
