Description

Technical Field

[0001] This utility model relates to furniture, and more particularly to a modular airbag assembly and mattress. Background Technology

[0002] Airbag mattresses, as a type of bedding product offering adjustable support and comfort, have been widely used in medical rehabilitation, home healthcare, and massage in recent years. Existing airbag mattresses typically consist of multiple airbag units, which are connected to a control box located at the foot or leg area of ​​the bed via silicone air tubes. The control box contains multiple pumps and solenoid valves, which alternately control the inflation and deflation of the airbags by switching valves. However, existing airbag mattresses still have some shortcomings: for example, 1. The gas supply pipeline is complex and occupies a large space. To accommodate the air supply pipes and control box, the mattress needs to have irregularly shaped slots. The air pipes are thick and long, making the assembly process complex, increasing production costs and assembly time, and also affecting the overall aesthetics and comfort of the mattress.

[0003] 2. The control system is inefficient and provides a poor user experience. Adjacent airbags cannot inflate and deflate simultaneously, resulting in low control efficiency and a poor user experience. Additionally, the limited space in the rear control box makes adding multiple solenoid valves difficult in terms of space layout and increases costs.

[0004] Therefore, a modular airbag assembly and mattress that does not require pipe connection to an external air source, is easy to lay out, and has high inflation and deflation efficiency needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to address the defects and deficiencies of the existing technology by providing a modular airbag assembly and mattress, which solves at least one of the above-mentioned technical problems. It has the advantages of not requiring pipe connection to an external air source, being easy to lay out, and having high inflation and deflation efficiency.

[0006] To achieve the above objectives, this utility model provides a modular airbag assembly, which is modularly spliced ​​to form an airbag support device, including: an airbag body, a control box disposed at the bottom of the airbag body, and a control main board, an air pump assembly and a solenoid valve installed in the control box; The control motherboard is electrically connected to the air pump assembly and the solenoid valve, and is signal-connected to an external motherboard. The solenoid valve is connected to the air inlet of the air pump assembly and to the airbag body, so as to inflate or deflate the airbag body under the control of the control board.

[0007] Optionally, the airbag body includes multiple layers of airbag sections connected sequentially in a vertical direction, with adjacent airbag sections connected to form an integral airbag cavity, and the horizontal projected area of ​​the upper airbag section is larger than the horizontal projected area of ​​the lower airbag section, so that the airbag body as a whole has a stepped shape that is wider at the top and narrower at the bottom.

[0008] Optionally, the horizontal projection of the airbag portion in each layer is square.

[0009] Optionally, the solenoid valve is suspended and mounted inside the control box via a first shock absorber.

[0010] Optionally, the air pump assembly includes: an air pump mounting housing, a flexible shock-absorbing sleeve, and an air pump; The flexible shock-absorbing sleeve is fitted around the outer periphery of the air pump, and the air pump is elastically installed inside the air pump mounting housing.

[0022] Please refer to Figures 1 to 9 This utility model embodiment provides a modular airbag assembly 100 that can be modularly assembled to form an airbag support device. The airbag support device can be, but is not limited to, sofas, massage chairs, mattresses 1000, and outdoor airbag products. The modular airbag assembly 100 is described below using a mattress 1000 as an example. The modular airbag assembly 100 includes: an airbag body 1, a control box 2, a control main board 3, an air pump assembly 4, and a solenoid valve 5.

[0023] The airbag body 1 is used to provide support and load-bearing functions for the user. An airbag cavity a is formed inside the airbag body 1 for storing air. Inflating the airbag cavity a can cause the airbag to expand to support the user.

[0024] The control box 2 is located at the bottom of the airbag body 1. In this embodiment, the control box 2 is detachably installed at the bottom of the airbag body 1. The control box 2 contains a control main board 3, an air pump assembly 4, and a solenoid valve 5.

[0025] The control board 3 is electrically connected to the air pump assembly 4 and the solenoid valve 5, and is also signal-connected to an external board (not shown in the figure). Optionally, the control board 3 is connected to the air pump assembly 4 and the solenoid valve 5 via wires (not shown in the figure), and the signal connection to the external board can be made via a signal cable or wirelessly; no specific limitation is made here.

[0026] Solenoid valve 5 is connected to the air inlet e of air pump assembly 4 and to airbag body 1, so as to inflate or deflate airbag body 1 under the control of control board 3. That is, solenoid valve 5 can receive gas delivered by air pump assembly 4 and inflate airbag body 1. Alternatively, solenoid valve 5 can deflate airbag body 1 under the control of control board 3.

[0027] Understandably, after receiving the control signal from the external mainboard, the control board 3 controls the working state of the air pump assembly 4 and the solenoid valve 5, thereby completing the inflation and deflation of the airbag body 1. Specifically, the method by which the control board 3 receives the control signal and controls the air pump assembly 4 and the solenoid valve 5 is existing technology, and therefore will not be elaborated on here.

[0028] The modular airbag assembly 100 integrates the air pump assembly 4, solenoid valve 5, and control main board 3 into the control box 2 at the bottom of the airbag, eliminating the need for connecting to an external air source via pipelines. This simplifies the internal pipeline layout of the mattress 1000, reduces space occupation, lowers assembly costs, and enhances the overall aesthetics. Furthermore, each airbag module can be independently controlled for inflation or deflation, unaffected by adjacent airbag modules, thus improving control efficiency. In addition, the modular design facilitates the mattress 1000's assembly, expansion, and maintenance as needed.

[0029] Alternatively, please refer to Figure 5 and Figure 6In this embodiment, the airbag body 1 includes multiple layers of airbag sections 11 connected sequentially in a vertical direction. In this embodiment, there are four layers; however, in other embodiments, it can be set to two, three, or more layers depending on actual needs. Adjacent airbag sections 11 are interconnected to form an integral airbag cavity a, meaning the internal gas of each layer of airbag sections 11 is interconnected, allowing inflation and deflation operations to be performed through the same air passage. The horizontal projected area of ​​the upper airbag section 11 is larger than that of the lower airbag section 11, giving the airbag body 1 an overall stepped shape that is wider at the top and narrower at the bottom. That is, the dimensions of each airbag section 11 decrease sequentially from top to bottom, forming a three-dimensional structure similar to a "T" shape or a step. Thus, when users of different weights use the airbag, the airbag body 1 will produce a layered compression effect due to the different applied pressure. Lighter users primarily compress the upper airbag section 11 for a gentler support, while heavier users will compress layer by layer down to the lower airbag section 11 for stronger support. This achieves layered cushioning and adaptive support, enabling the modular airbag assembly 100 to automatically adjust the support strength according to the user's weight, significantly improving comfort and fit.

[0030] Alternatively, please refer to Figure 6 In this embodiment, the horizontal projection of each airbag layer 11 is square. Thus, adjacent modular airbag assemblies 100 can be tightly joined in the horizontal direction to form a regular matrix support surface, thereby improving the overall stress uniformity and stability. Of course, in other embodiments, the horizontal projection of each airbag layer 11 can also be circular, rectangular, square, or elliptical; no specific limitation is made here.

[0031] To effectively isolate the vibration generated by the solenoid valve 5 during operation and prevent the vibration from being transmitted to the airbag body 1 via the control box 2 and further to the user, thereby significantly reducing the noise of the solenoid valve 5 during operation and improving the shock absorption and noise reduction performance of the modular airbag assembly 100. Optionally, please refer to... Figure 6 and Figure 8 In this embodiment, the solenoid valve 5 is suspended within the control box 2 via a first shock absorber 61. Optionally, the control box 2 also includes a mounting plate 7, on which the solenoid valve 5 is fixedly mounted. The mounting plate 7 has first shock absorbers 61 at its four corners, and the mounting plate 7 is suspended within the control box 2 via the first shock absorbers 61. When the solenoid valve 5 inflates or deflates, the mechanical vibration it generates is further attenuated by the first shock absorbers 61, thereby significantly reducing the transmission of vibration to the control box 2 and the airbag body 1, and lowering the overall noise. Optionally, the first shock absorber 61 is an elastic shock-absorbing nail made of elastic rubber material, possessing good resilience and vibration absorption performance.

[0032] To effectively isolate and attenuate the vibration and noise generated by the air pump 43 during operation, and prevent its transmission to the control box 2 and the airbag body 1, thereby further improving the shock absorption performance and noise reduction effect of the modular airbag assembly 100. Optionally, please refer to Figure 6 and Figure 9 In this embodiment, the air pump assembly 4 includes an air pump mounting housing 41, a flexible damping sleeve 42, and an air pump 43. The flexible damping sleeve 42 is fitted around the outer periphery of the air pump 43, elastically mounting the air pump 43 within the air pump mounting housing 41. The air pump mounting housing 41 is suspended within the control box 2 via a second damping member 62. Thus, the flexible damping sleeve 42 directly buffers the vibrations generated during the operation of the air pump 43, while the second damping member 62 prevents the air pump mounting housing 41 from making rigid contact with the control box 2 and further absorbs vibration and impact, achieving dual isolation from noise and vibration.

[0033] Alternatively, please refer to Figure 8 and Figure 9 In this embodiment, the solenoid valve 5 has a first valve port k1, a second valve port k2, and a third valve port k3. The first valve port k1 is connected to the air inlet e of the air pump assembly 4, the second valve port k2 is connected to the airbag body 1, and the third valve port k3 is used for venting. Specifically, the first valve port k1 of the solenoid valve 5 is connected to the air inlet e of the air pump assembly 4 through the first air supply pipe 81, and is connected to the airbag body 1 through the second air supply pipe 82.

[0034] During inflation: The control board 3 outputs a control signal, causing the solenoid valve 5 to be in a state where the first valve port k1 and the second valve port k2 are connected, and the third valve port k3 is closed. At this time, the compressed gas output from the air pump assembly 4 enters the solenoid valve 5 through the first valve port k1, and then enters the airbag body 1 through the second valve port k2, thus inflating the airbag body 1. During deflation: The control board 3 switches the state of the solenoid valve 5, causing the solenoid valve 5 to be in a state where the second valve port k2 and the third valve port k3 are connected, and the first valve port k1 is closed. At this time, the gas inside the airbag body 1 is discharged through the second valve port k2 and then discharged to the outside through the third valve port k3, thus deflating the airbag body 1. In the holding state: When the airbag body 1 reaches the target air pressure, the solenoid valve 5 can be in a closed state where the three valve ports are not connected to each other, in order to maintain the stable air pressure inside the airbag body 1 and prevent gas leakage.

[0035] To further reduce the operating noise of the modular airbag assembly 100, optionally, in this embodiment, a silencer 9 is fitted onto the third valve port k3.

[0036] To ensure reliable assembly of the control box 2 and the airbag body 1, optionally, please refer to... Figure 5 and Figure 6In this embodiment, the control box 2 includes a bottom shell 21 and a top cover 22. The top cover 22 is fitted onto the bottom shell 21, specifically by means of screws or clips. After the top cover 22 and the bottom shell 21 are fitted together, an installation cavity c is formed inside for installing the control main board 3, the air pump assembly 4, and the solenoid valve 5.

[0037] The bottom of the airbag body 1 is provided with a fixing plate 12 that is positioned opposite to it. The fixing plate 12 can be folded and clamped between the bottom shell 21 and the top cover 22 to fix the control box 2 to the bottom of the airbag body 1. During assembly, the fixing plate 12 at the bottom of the airbag body 1 is folded inward so that it is located at the bottom of the top cover 22. Then, the bottom shell 21 and the top cover 22 are fixed with screws, so that the fixing plate 12 is clamped and pressed and fixed between the top cover 22 and the bottom shell 21, thereby achieving a reliable connection between the control box 2 and the airbag body 1.

[0038] Further, please refer to Figure 6 and Figure 7 In this embodiment, the fixing piece 12 is provided with a limiting hole o, and the upper cover 22 is provided with a protrusion 221 at a corresponding position. The limiting hole o can be fitted onto the protrusion 221 to pre-fix it with the upper cover 22. The bottom shell 21 is provided with a clamping notch b at a position corresponding to the fixing piece 12 to clamp the fixing piece 12 when the upper cover 22 and the bottom shell 21 are closed. That is, during assembly, the fixing piece 12 at the bottom of the airbag body 1 can be folded inward first, and fixed to the protrusion 221 of the upper cover 22 through the limiting hole o, and then the upper cover 22 and the bottom shell 21 can be closed and fixed. This can further increase the stability of the assembly of the control box 2 and the airbag body 1.

[0039] Please refer to Figure 1 and Figure 2 Another aspect of this utility model embodiment provides a mattress 1000, including a mattress support frame 200 and a plurality of modular airbag assemblies 100 as described above, installed within the mattress support frame 200; the plurality of modular airbag assemblies 100 are connected to the same external mainboard via wires to receive inflation / deflation control signals. Since the mattress 1000 possesses all the structures and connections of the modular airbag assemblies 100, it has all the advantages of the modular airbag assemblies 100, which will not be elaborated upon here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
