Description

Technical Field

[0001] This invention belongs to the field of household appliances, and specifically relates to a cushioning airbag and a method for manufacturing the cushioning airbag. Background Technology

[0002] Cushioning airbags, as products that provide cushioning pressure, are widely used in various products, such as bag shoulder straps, seat cushions, back cushions, mattresses, shoe insoles, etc., to cushion the pressure on the user's contact area.

[0003] However, existing airbag cushions have a problem where some of the gas leaks out slowly through the air inlet after being injected into the airbag. As a result, the airbag cushion leaks slowly, causing the airbag to become insufficient after a period of use, requiring re-inflation, which is inconvenient.

[0004] Therefore, there is a need for a cushioning airbag that can reliably allow one-way air intake into the airbag and a method for manufacturing it. Summary of the Invention

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] [First Implementation Method] Figure 1 The cushioning airbag 1000 of this embodiment is shown, which includes a cushion body 10 and an inflation / deflation component (not shown) disposed on the cushion body 10.

[0022] The cushion 10 includes a main body 1, and a plurality of air sacs 100 and airways 200 that bulge out from the main body 1. The plurality of airways 200 bulge toward at least one side surface of the cushion 10, and adjacent air sacs 100 are connected via airways 200. Throughout the main body 1, the cushion 10 is not bulged and surrounds the periphery of the plurality of air sacs 100 and airways 200.

[0023] An inflation / deflation mechanism is disposed within the cushion 10 and is used to control the inflation and deflation of multiple airbags 100. The inflation / deflation mechanism includes an inflation component 300 and a deflation component 400. The inflation component 300 controls the inflation of the multiple airbags 100, allowing gas to enter the multiple airbags 100 in one direction and preventing gas from escaping to the outside. The inflation component 300 includes at least a one-way air intake component 330, which is a component capable of enabling one-way air intake and is disposed within the airbags 100.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the pad 10 is a structure formed by overlapping and bonding a first pad 101 and a second pad 102. The first pad 101 and the second pad 102 contain a heat-fusible flexible material, such as polyether-type TPU, polyester-type TPU (Thermoplastic polyurethanes), PVC, EVA, or other heat-fusible flexible materials. The pad 10 is formed by pressing the first pad 101 and the second pad 102 together by means such as welding. The second padding layer 102 is pressed together with a portion of the first padding layer 101 to form the aforementioned main body 1. The main body 1 is the area where the second padding layer 102 and the first padding layer 101 are tightly adhered to each other without bulging when inflated. Furthermore, another portion of the second padding layer 102 and the first padding layer 101 is not pressed together, thus forming at least a plurality of air bladders 100 and a plurality of air passages 200 arranged in a predetermined shape on the first padding layer 101 and bulging away from the second padding layer 102. The internal gas of the plurality of air bladders 100 and the plurality of air passages 200 is sealed and isolated from the outside of the padding body 10. Additionally, the plurality of air bladders 100 and the plurality of air passages 200 may be arranged in a raised manner on one or both of the first padding layer 101 and the second padding layer 102. The multiple airbags 100 and multiple air channels 200 arranged in a raised shape are formed on the first pad 101 and the second pad 102 before the two pads are pressed together. Therefore, after the pad body 10 is formed, the multiple airbags 100 and multiple air channels 200 are raised even when not inflated, and are easy to sink when pressed. After inflation, the airbags 100 are full and are not easy to sink when pressed. Alternatively, it is not necessary to form a raised shape on the first pad 101 and the second pad 102 in advance. In such a cushioning airbag pad 1000, it is flat when not inflated and bulges out into a double-sided raised shape after inflation.

[0025] The main body 1 includes a first pressing portion 10A, a second pressing portion 10B, and a first embossed portion 10C. In the first pressing portion 10A, a portion of the main body 1 is pressed once. In the second pressing portion 10B, a portion of the main body 1 is pressed once in a process different from the pressing process forming the first pressing portion 10A. Viewed from above, the first pressing portion 10A overlaps with at least a portion of the air intake portion 3301 of the one-way air intake member 330, and the first embossed portion 10C also overlaps with at least a portion of the air intake portion 3301 of the one-way air intake member 330. In the first embossed portion 10C, a portion of the main body 1 is pressed twice. The first embossed portion 10C is connected to both the first pressing portion 10A and the second pressing portion 10B, thus situated between the first pressing portion 10A and the second pressing portion 10B. The first pressing portion 10A, the second pressing portion 10B, and the first embossed portion 10C together surround the air intake airbag 121. In the first embossed portion 10C, the outer surface of at least one pad layer (i.e., the first pad layer 101 and / or the second pad layer 102) of the pad body 10 is embossed.

[0026] The embossing of the first embossed portion 10C can be formed by the melting and pressing of the heat-fusible flexible material contained in the pad 10 during the pressing process. For example, steps or wrinkles can be formed at the boundary between the first embossed portion 10C and the first pressing portion 10A, and at the boundary between the first embossed portion 10C and the second pressing portion 10B. Such steps or wrinkles can be formed due to factors such as inconsistent molds or misalignment during pressing. In addition, the first pad layer 101 and the second pad layer 102 can be a composite structure with an inner layer of heat-fusible flexible material and an outer layer of textile material. Therefore, the hardness of the first embossed portion 10C may be harder than that of the first pressing portion 10A and the second pressing portion 10B in a single pressing process, and its surface may be smoother than that of the first pressing portion 10A and the second pressing portion 10B. It is speculated that after the second pressing, the portion of the heat-fusible flexible material that penetrates into the textile material is greater than that of the first pressing portion 10A and the second pressing portion 10B, increasing the density of the pad 10 at the first embossed portion 10C and making it harder. In addition, because a portion of the heat-fusible flexible material of the inner layer penetrates into the outer surface of the textile material (i.e., the outer surface of the pad 10), it fills the gaps between the textile materials, making the surface smoother.

[0027] The multiple airbags 100 include an inflatable airbag 110 that serves as the starting point for internal gas flow and a deflated airbag 140 that serves as the ending point for internal gas flow. The inflatable airbag 110 and the deflated airbag 140 are connected via other airbags 120 and multiple airways 200. The multiple airbags 100 can be inflated by operating the inflatable airbag 110, and the multiple airbags 100 can be deflated by operating the deflated airbag 140. Furthermore, the other airbags 120 include an intake airbag 121 that serves as the starting point for internal gas flow, and the multiple airways 200 include an intake airway 210 and multiple ventilation airways 220. The intake airway 210 serves as the starting point for gas flow through all airways 200, and the multiple ventilation airways 220 are connected downstream of the intake airbag 121. The air intake duct 210 connects the upstream inflatable airbag 110 and the downstream air intake airbag 121, allowing the inflatable airbag 110 to communicate with other airbags 120. A one-way air intake element 330 is installed in the air intake airbag 121. Through this one-way air intake element 330, gas inflated into the inflatable airbag 110 can enter the air intake airbag 121 in a unidirectional manner. Furthermore, multiple ventilation ducts 220 connect adjacent airbags 120 and other airbags 120 with the deflation airbag 140, ensuring that the gas entering the air intake airbag 121 unidirectionally flows smoothly through all airbags 100.

[0028] like Figure 1 As shown, a first pressing portion 10A is disposed between the inflatable airbag 110 and the intake airbag 121, and has at least a portion connected to the intake airbag 121, which is divided into two parts by the intake air passage 210. A first embossed portion 10C is connected to the two sides of the first pressing portion 10A away from the intake air passage 210. A second pressing portion 10B is formed in the area of ​​the main body 1 other than the first pressing portion 10A and the first embossed portion 10C, and surrounds the outer periphery of the first pressing portion 10A, all airbags 100, and all air passages 200. Therefore, the intake airbag 121 is connected and surrounded by the first pressing portion 10A, the second pressing portion 10B, and the first embossed portion 10C, or the intake airbag 121 is connected and surrounded by the first pressing portion 10A and the second pressing portion 10B.

[0029] In this embodiment, such as Figure 1 and Figure 3As shown, the one-way air inlet 330 of the inflation component 300 is installed in the air intake bladder 121 and sandwiched between the first pad 101 and the second pad 102 of the cushioning airbag pad 1000. The one-way air inlet 330 allows gas to enter the interior of the plurality of airbags 100 in one direction. The one-way air inlet 330 is a thin film structure with a one-way air intake channel 3300 forming inside, which connects the inflation bladder 110 and the air intake bladder 121 in one direction. The one-way air intake channel 3300 extends along the air intake direction D (i.e., from the inflation bladder 110 toward the air intake bladder 121), and the air intake part 3301 and the air outlet part 3302 are connected through the one-way air intake channel 3300, so that the one-way air intake channel 3300 can connect the inflation bladder 110 and the air intake bladder 121. Gas sequentially enters the air intake 3301 of the one-way air intake component 330 from the inflatable airbag 110 and the air intake duct 210. After passing through the one-way air intake channel 3300, it enters the air intake airbag 121 from the air outlet 3302 of the one-way air intake component 330, and diffuses to the other airbags 120 via the ventilation duct 220. In its natural state, the one-way air intake channel 3300 in the one-way air intake component 330 is closed, preventing gas flow. The one-way air intake component 330 can be expanded under pressure difference, thereby allowing gas to flow through the one-way air intake channel 3300, thus achieving one-way air intake. The one-way air intake component 330 is made of materials such as polyether-type TPU, polyester-type TPU (Thermoplastic polyurethanes), PVC, EVA, or other plastic sheet materials.

[0030] In this embodiment, such as Figure 5 As shown, the one-way air intake 330 is, for example, an integrated structure formed by combining two sheets 331 and 332. The second and fourth end edges of the first sheet 331 and the second sheet 332 are joined together, for example, by welding, so that the second and fourth end edges of the one-way air intake 330 are closed and the first and third end edges are open. The first sheet 331 and the second sheet 332 are soft and flat films (e.g., plastic sheets), such as polyether-type TPU, polyester-type TPU (Thermoplastic polyurethanes), PVC, EVA, or other plastic sheet materials. A one-way air intake channel 3300 is formed between the film-shaped first sheet 331 and the film-shaped second sheet 332. Specifically, the inner walls of the first sheet 331 and the second sheet 332 that come into contact with each other are smooth, so that when the first sheet 331 and the second sheet 332 come into contact with each other, they can adhere to each other, thus sealing the one-way air intake channel 3300. Furthermore, the pressure difference allows the one-way air intake channel 3300 to open.

[0031] like Figure 4As shown, the four end edges of the unidirectional air intake 330 are, in sequence, a first end edge 330a, a second end edge 330b, a third end edge 330c, and a fourth end edge 330d. The first end edge 330a and the third end edge 330c are opposite each other and open (i.e., the first sheet 331 and the second sheet 332 can be separated here), while the second end edge 330b and the fourth end edge 330d are opposite each other and closed, forming a closed portion 3304 (i.e., the first sheet 331 and the second sheet 332 at the closed portion 3304 cannot be separated). The unidirectional air intake channel 3300 extends from the first end edge 330a to the third end edge 330c. The first end edge 330a extends to the air intake passage 210 and overlaps with the first pressing portion 10A and the first embossed portion 10C.

[0032] like Figure 3 As shown, in the unidirectional air intake 330, the air intake portion 3301 is installed in an open state on the side of the air intake 121 near the inflatable airbag 110. For example, the first sheet 331 of the air intake portion 3301 is fixedly installed on the first pad 101, and the second sheet 332 is fixedly installed on the second pad 102. It is understood that the air intake portion 3301 can also be in a closed state, as long as the first sheet 331 and the second sheet 332 can be separated under a pressure difference, and can be designed arbitrarily according to actual needs. The air intake portion 3301 is a closed structure. Preferably, the inner walls of the first sheet 331 and the second sheet 332 in the air intake portion 3301 are non-smooth or coated with antistatic agents, lubricants, release agents, etc., to inhibit surface adsorption. It is understood that the first sheet 331 and the second sheet 332 at a portion of the air intake portion 3301 can also be fixedly installed in the air intake duct 210 and / or the inflatable airbag 110.

[0033] The air outlet 3302 is sandwiched between the closing portions 3304 of the second end edge 330b and the fourth end edge 330d, and is away from the air intake passage 210. The first sheet 331 and the second sheet 332 at the air outlet 3302 are not pressed together, allowing the air outlet 3302 to communicate across the air intake direction D. Alternatively, a portion of the air outlet 3302 can be sealed by pressing or other methods. For example, a closing portion 3303 can be provided in the air outlet 3302, and the closing portion 3303 can be used to join the first sheet 331 and the second sheet 332 together, for example, by welding. The closing portion 3303 is formed, for example, on the third end edge 330c. Through this closing portion 3303, the unidirectional air intake member 330 can assist the air outlet 3302 in closing when it ages, preventing air leakage caused by the air outlet 3302 not being able to close completely due to aging.

[0034] In addition, the inflation component 300 may also include an air inlet valve 310. The air inlet valve 310 is installed in the inflatable airbag 110. The air inlet valve 310 may be a one-way valve that allows external gas to enter in one direction, or it may be a cover for connecting or isolating the inside and outside of the pad 10.

[0035] The inflatable component 300 may also include an elastomer 320. The elastomer 320 is installed in the inflatable airbag 110 and supports the inflation of the inflatable airbag 110 in its natural state. Because the air inlet valve 310 is a one-way valve or a cover that opens, the gas inside and outside the pad 10 is connected, allowing gas to enter and fill the inflatable airbag 110. In addition, when the inflatable airbag 110 is pressed, because the air inlet valve 310 is a one-way valve or a cover that closes, the gas inside and outside the pad 10 is isolated, preventing gas from leaking to the outside. At this time, under the action of the air pressure difference, the one-way air inlet 330 allows gas to enter the interior of the plurality of airbags 100 in one direction. The gas from the outside in the inflatable airbag 110 enters the air inlet airbag 121 through the air inlet passage 210. Then the inflatable airbag 110 is released. Under the elastic reset action of the elastic body 320, the elastic body 320 supports the inflatable airbag 110 to reset. At this time, under the action of the air pressure difference, gas is drawn into the inflatable airbag 110, while the one-way air inlet 330 prevents the gas in the air inlet airbag 121 from being drawn into the inflatable airbag 110. By repeatedly pressing and releasing the air bladder 110, the pad 10 can be inflated. It is understood that the elastomer 320 can be any type of sponge, plastic, spring, rubber, or silicone—any elastic component will suffice. Alternatively, the elastomer 320 can be omitted, and gas can be supplied to the air bladder 110 using an external inflation device.

[0036] A venting component 400 is installed in the venting airbag 140 to allow gas from the multiple airbags 100 to be released to the outside. In this embodiment, the venting component 400 may be a one-way valve that allows internal gas to be released in one direction, or it may be a cover that connects or isolates the inside and outside of the pad 10, and venting is performed by pressing a suction pump on the pad 10 or the outside.

[0037] The cushioning airbag 1000 of this embodiment can be used Figure 8 The method shown is used to manufacture it.

[0038] First, in step S101, a first pad 101 and a second pad 102 are prepared.

[0039] Next, in step S102, the one-way air intake component 330, which has the fixture K fitted inside the air intake section 3301, is placed into the air intake bag 121. At this time, as... Figure 2 and Figure 7As shown, fixture K is sandwiched between the first sheet 331 and the second sheet 332, and the one-way air intake 330 is sandwiched between the first pad 101 and the second pad 102. With the one-way air intake 330 embedded within the air intake bladder 121, the air intake pressing area 330Y of the press pad 10 is compressed. In the air intake pressing area 330Y, a portion of the air intake portion 3301 of the one-way air intake 330 overlaps with the main body 1. Thus, at the air intake portion 3301, the first sheet 331 is bonded to the first pad 101, and the second sheet 332 is bonded to the second pad 102. The bulging shape of the air intake bladder 121 on the first pad 101 allows the air intake portion 3301 to remain open. The air intake pressing area 330Y may overlap with the air intake passage 210, or it may not. The pressing can be performed using a pressing device (not shown) with an upper and lower die facing each other. By bringing the upper and lower dies close together and pressing the first pad 101 and the second pad 102 against each other, the main body 1 can be pressed together. In this step, the area where the upper and lower dies are pressed against each other corresponds to the air intake pressing area 330Y.

[0040] Next, in step S103, the pad pressing area 10Y in the pressing body 1 overlaps with the one-way air inlet 330 and the air inlet pressing area 330Y. A first embossed portion 10C is formed at the overlapping position of the pad pressing area 10Y and the air inlet pressing area 330Y. A first pressing portion 10A is formed in the air inlet pressing area 330Y except for the first embossed portion 10C. A second pressing portion 10B is formed in the pad pressing area 10Y except for the first embossed portion 10C. The first embossed portion 10C is located between the first pressing portion 10A and the second pressing portion 10B. In step S103, pressing can be performed using a pressing device. Unlike step S102, in step S103, the area where the upper mold and the lower mold press against each other corresponds to the pad pressing area 10Y.

[0041] Furthermore, if the inflatable airbag 110 is equipped with an elastomer 320, the elastomer 320 can be placed inside the inflatable airbag 110 in any step prior to step S103.

[0042] According to the above method, the cushioning airbag 1000 of this application can be manufactured. According to the cushioning airbag 1000 of this application, one-way air intake can be reliably carried out inside the airbag 100.

[0043] [Second Implementation] In the cushioning airbag 1000 of this embodiment, the one-way air intake 330 can be as follows: Figure 6As shown, in addition to being located inside the air intake 121, the second and fourth end edges 330b and 330d on both sides of the one-way air intake 330 can extend beyond the air intake 121 and overlap with a portion of the main body 1.

[0044] The intake component pressing area 330Y can be like Figure 7 The air intake 121 is surrounded as shown. Depending on the pressing position of the pad pressing area 10Y, the air intake 121 can be formed to be surrounded only by the first pressing part 10A, or it can be formed as shown. Figure 6 As shown, it is surrounded by the first pressing portion 10A and the first embossing portion 10C. Therefore, the second and fourth end edges 330b and 330d on both sides of the one-way air intake 330, as well as the first end edge 330a, also overlap with the first pressing portion 10A, or with the first pressing portion 10A and the first embossing portion 10C.

[0045] Furthermore, the intake component pressing area 330Y may or may not overlap with the intake duct 210.

[0046] Except for the aspects described above, the cushioning airbag 1000 of this embodiment uses the same structure and manufacturing method as the first embodiment.

[0047] [Third Implementation Method] like Figure 9 As shown, in the buffer airbag cushion 1000 of this embodiment, the main body 1 further includes a second embossed portion 10BB. The second embossed portion 10BB intersects or is perpendicular to the air intake direction D of the one-way air intake member 330, and is clampedly connected to both sides of the air intake airbag 121. The second pressing portion 10B is divided into two parts, a first part 10B1 and a second part 10B2, by the second embossed portion 10BB.

[0048] The first part 10B1 and the second part 10B2 of the second pressing part 10B are pressed once in different steps, and the second embossed part 10BB is pressed twice.

[0049] The second embossed part 10BB can also present a similar embossing as the first embossed part 10C, forming stepped, wrinkled, or other textures at the boundary, and can also be harder and have a smoother surface.

[0050] Except for the aspects described above, the cushioning airbag 1000 of this embodiment uses the same configuration as the first embodiment.

[0051] See below for reference. Figure 10 This describes the manufacturing method of the cushioning airbag 1000 of this application.

[0052] First, in step S101, a first pad 101 and a second pad 102 are prepared.

[0053] Next, in step S301, the first pad 101 and the second pad 102 are placed overlappingly between the upper mold and the lower mold of the pressing device to press a first region 10Y1 of a portion of the pad 10.

[0054] Next, the same step S102 as described above is performed. In step S102, the one-way air intake 330 is pressed into the body 1 by pressing the air intake pressing area 330Y.

[0055] Next, in step S302, a portion of the second region 10Y2 of the pad 10 is pressed together. This forms the first part 10B1, the second part 10B2, and the second embossed part 10BB. The second embossed part 10BB is formed in the portion of the second region 10Y2 that overlaps with the first region 10Y1, the second part 10B2 is formed in the portion of the second region 10Y2 that does not overlap with the first region 10Y1, and the first part 10B1 is formed in the portion of the first region 10Y1 that does not overlap with the second region 10Y2.

[0056] According to the above method, the cushioning airbag 1000 of this application can be manufactured. According to the cushioning airbag 1000 of this application, one-way air intake can be reliably carried out inside the airbag 100.

[0057] It is understood that this embodiment splits step S103 used in the first and second embodiments into two steps, S301 and S302. Therefore, compared to the first and second embodiments, the unidirectional air inlet 330, especially the air outlet 3302, is only heated in step S302, thus the unidirectional air inlet 330 is less prone to heat deformation. Therefore, the cushioning airbag 1000 and its manufacturing method according to this embodiment also achieve advantages such as high yield, long service life, and good inflation performance.
