Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation, and in particular relates to an inflatable thermal insulation structural member. Background Art

[0002] Camping has become a common form of leisure and entertainment, and improving the quality of camping has become a common concern. Providing high-insulation outdoor gear is a key issue. Insulated boxes can keep food hot or cold for extended periods, while thermal sleeping mats keep campers comfortable and warm at night.

[0003] Current insulation materials on the market are generally bulky, non-foldable, and heavy. High-insulation sleeping pads typically use a center-filled insulation material, which makes them heavy and difficult to fold, adding to the burden of carrying them outdoors. Other sleeping pads, while addressing weight and portability issues, are complex, costly, and difficult to manufacture.

[0004] Therefore, there is an urgent need to develop an inflatable heat-insulating structural component that is light in weight, easy to carry, and easy to produce and process. Utility Model Content

[0005] In response to the technical problems mentioned above, the present invention aims to provide an inflatable heat-insulating structural component that can solve at least one of the above technical problems.

[0006] According to the utility model, an inflatable heat-insulating structural component is provided, comprising: an inflatable body; a plurality of tie rods arranged in the inflatable body, the tie rods connecting the upper and lower surfaces of the inflatable body; and at least one layer of heat-insulating layer arranged in the inflatable body, the heat-insulating layer being arranged on the tie rods through a clamping assembly, and the inflatable body after being inflated straightens the tie rods, and further straightens the heat-insulating layer.

[0007] In a specific embodiment, the snap-fit ​​assembly includes: snap-fit ​​sockets provided at the front and rear ends of the tie rod; and openings provided on the thermal insulation layer corresponding to the position of the tie rod for adapting to the snap-fit ​​sockets.

[0008] In a specific embodiment, the snap-on is configured as an incision opened along the front-to-back direction on the tie rod and extending to the outside, and the opening is configured as an incision opened along the front-to-back direction inside the thermal insulation layer. The tie rod penetrates the opening of the thermal insulation layer and the snap-on is engaged with the opening.

[0009] In a specific embodiment, the distance between the snap-in openings on the front and rear sides of the tie bar is greater than the front and rear distance of the opening of the thermal insulation layer.

[0010] In a specific embodiment, a plurality of the thermal insulation layers are arranged in the inflatable body, and a plurality of bayonet holes are sequentially provided at the front and rear ends of the tie rod along the up and down directions, and the number of the bayonet holes is adapted to the number of the thermal insulation layers.

[0011] In a specific embodiment, the inflatable body includes a first surface layer and a second surface layer respectively arranged on the upper and lower sides of the reinforcement.

[0012] In a specific embodiment, the lacing rod is made of cloth or TPU material.

[0013] In a specific embodiment, the heat insulation layer is made of aluminum-plated film material.

[0014] In a specific embodiment, the inflatable body is made of TPU material.

[0015] According to the present invention, a production process for producing the inflatable heat-insulating structural member provided by the present invention is also provided, comprising the following steps:

[0016] Connecting the first connecting portion of the reinforcement to the second surface layer of the inflatable body;

[0017] The plurality of thermal insulation layers are all arranged on the position of the tie bar close to the first connecting portion through the clamping assembly;

[0018] Connecting the third connecting portion of the reinforcement to the first surface layer;

[0020] The edges of the first and second facings are connected.

[0021] Compared with the prior art, the advantages of this application are as follows.

[0022] The inflatable heat-insulating structure provided by the utility model comprises an inflatable body, an insulation layer, and tie bars. When inflated, the inflatable body is filled with gas, which straightens the tie bars, and thus the insulation layer. The straightened insulation layer divides the interior of the inflatable body into multiple insulating air chambers, thereby enhancing the thermal insulation effect. When deflated, the inflatable heat-insulating structure can be folded for easy portability.

[0023] The heat insulation layer is arranged on the tie rod through the clamping assembly. When the heat insulation layer is set to multiple layers, the multiple layers of heat insulation layer can be distributed on the tie rod in an interval manner through the clamping assembly, thereby dividing the interior of the inflatable body into multiple insulation air chambers, thereby improving the heat preservation and insulation capabilities.

When the thermal insulation layer is provided as multiple layers, correspondingly, a plurality of snap-ons are provided on the tie bar in an interval manner in the up and down directions, which are adapted to the number of thermal insulation layers. Under this arrangement, on the one hand, the multiple layers of thermal insulation layer can divide the interior of the inflatable body into more insulating air chambers, thereby improving the thermal insulation capacity; on the other hand, when producing inflatable thermal insulation structural parts, the first connecting portion of the tie bar is first fixedly connected to the second surface layer of the inflatable body, and then all the thermal insulation layers are snapped onto the snap-on assembly closest to the first connecting portion, thereby leaving more space for the position of the tie bar close to the third connecting portion, facilitating the fixed connection of the third connecting portion of the tie bar to the first surface layer.

[0037] The present invention will be described below with reference to the accompanying drawings.

[0038] It should be noted that the directional terms or qualifiers "upper", "lower", "front", "back", "left", "right" etc. used in this application are all relative to the referenced Figure 1 They are not intended to define the absolute positions of the components involved, but may vary according to specific circumstances. Specifically, Figure 1 As shown, the directional terms or qualifiers "upper" and "lower" used in this application refer to the direction Figure 1 The direction of the z-axis in the present application, the directional terms or qualifiers "front" and "rear" refer to the direction of Figure 1 The direction of the y-axis in the present application, the directional terms or qualifiers "left" and "right" refer to the direction of Figure 1 The direction of the x-axis in .

[0039] Figure 1 The structure of the inflatable heat-insulating structural member 100 according to the present invention is shown. Figure 1 As shown, the inflatable heat-insulating structural member 100 includes an inflatable body 1 , tie bars 3 and a heat-insulating layer 2 .

[0040] Specifically, in this embodiment, the inflatable body 1 includes a first surface layer 11 and a second surface layer 12. The first surface layer 11 and the second surface layer 12 are both rectangular, and the inflatable body 1 is formed after the edges of the first surface layer 11 and the second surface layer 12 are fixed and sealed.

[0041] It is easy to understand that an inflation port (not shown in the figure) is provided on the inflatable body 1, and the inflation port can be provided on the first surface layer 11 or the second surface layer 12, through which air can be inflated into the inflatable body 1. The specific structure of the inflation port is well known to those skilled in the art and will not be described in detail here.

[0042] It should be noted that the shapes of the first surface layer 11 and the second surface layer 12 are not limited to rectangles, and can also be set to circular, polygonal, irregular shapes, etc. according to actual needs.

[0043] like Figure 1 As shown, multiple tie bars 3 are arranged in the inflatable body 1, and the tie bars 3 connect the upper and lower surfaces of the inflatable body 1. The tie bars 3 include a first connection portion 31, a second connection portion 32, a third connection portion 33, and a fourth connection portion 34 arranged in sequence along the circumferential direction. Specifically, the first connection portion 31 of the tie bar 3 is fixedly connected to the second surface layer 12, and the third connection portion 33 of the tie bar 3 is fixedly connected to the second surface layer 12. After inflation, the overall thickness of the inflatable body 1 depends on the width of the tie bars 3 ( Figure 1 In the up and down directions), the main structure of the inflatable heat-insulating structural member 100 is formed.

[0044] In this embodiment, the tie bars 3 are constructed in the shape of long strips, and the sizes of the tie bars 3 are the same. A plurality of tie bars 3 are uniformly arranged in intervals along the left and right directions in the inflatable body 1, and the tie bars 3 are parallel to each other. The first connecting portion 31 of the tie bar 3 is welded to the second surface layer 12 and the first surface layer 11 by high-frequency welding to form a strip weld with high structural strength. After inflation, the inflatable body 1 presents a strip-shaped bulging structure as a whole due to the presence of the strip weld. Through this arrangement, it is possible to prevent the inflatable body 1 from becoming a balloon shape after inflation. Small strip arch structures are formed between the strip welds to play a supporting role. By setting the width of each tie bar 3, it is possible to ensure that the thickness of the inflatable body 1 after inflation remains substantially consistent.

[0045] It should be noted that the embodiment in which the dimensions of the tie bars 3 are the same is designed for the rectangular first surface layer 11 and the second surface layer 12. The length of each tie bar 3 ( Figure 1 The front-to-back direction in the figure needs to be adaptively changed according to the specific shapes of the first surface layer 11 and the second surface layer 12. For example, when the first surface layer 11 and the second surface layer 12 are set to be circular, the length of each tie rod 3 gradually decreases from the middle to the left and right sides to adapt to the circular structure.

[0046] Furthermore, when different thicknesses need to be set at different locations of the inflatable body 1 , this can be achieved by changing the widths of different tie bars 3 .

[0047] like Figure 1 As shown, at least one thermal insulation layer 2 is disposed within the inflatable body 1. The thermal insulation layer 2 is attached to the tie bars 3 via a snap-fit ​​assembly 4. After inflation, the inflatable body 1 straightens the tie bars 3, which in turn straightens the thermal insulation layer 2. When multiple thermal insulation layers 2 are disposed within the inflatable body 1, the multiple thermal insulation layers 2 are evenly spaced and disposed on the tie bars 3 via the snap-fit ​​assembly 4, thereby forming multiple insulating air chambers within the inflatable body 1 and enhancing the thermal insulation effect.

[0048] According to the present invention, in a specific embodiment, the snap-fit ​​assembly 4 includes snap-fit ​​sockets 41 provided at the front and rear ends of the tie rod 3 and openings 42 provided on the insulation layer 2 at positions corresponding to the tie rod 3 for matching with the snap-fit ​​sockets 41 .

[0049] like Figure 2 and Figure 3As shown, a snap-in 41 is provided on the second connection portion 32 and the fourth connection portion 34 of the tie bar 3. The snap-in 41 is configured as an incision opened along the front-to-back direction on the tie bar 3 and extending to the outside. The opening 42 is configured as an incision opened along the front-to-back direction inside the thermal insulation layer 2. The assembly process of the thermal insulation layer 2 and the tie bar 3 is as follows: the tie bar 3 is inserted into the opening 42 of the thermal insulation layer 2 along the up-down direction until the thermal insulation layer 2 is located at the position of the snap-in 41 of the tie bar 3, and then the thermal insulation layer 2 is snapped into the snap-in 41, completing the snap-in connection between the snap-in 41 and the opening 42.

[0050] The number of the slots 41 on each tie bar 3 corresponds to the number of the insulation layers 2. Specifically, in this embodiment, the number of insulation layers 2 is set to four, so four slots 41 are set on the front and back sides of each tie bar 3, corresponding to the four insulation layers 2. Figure 2 As shown, four clips 41 are evenly distributed on the tie rod 3 in an interval manner along the up and down directions.

[0051] Accordingly, the number of openings 42 on each insulation layer 2 corresponds to the number of tie bars 3. In other words, the number of openings 42 on the insulation layer 2 is equal to the number of tie bars 3, so that each tie bar 3 can be engaged with the insulation layer 2, and then after the inflatable body 1 is inflated, the multiple tie bars 3 can straighten the insulation layer 2.

[0052] In a preferred embodiment, the distance between the front and rear ends of the tie rod 3 is greater than the front and rear distance of the opening 42 of the thermal insulation layer 2. Figure 2 and Figure 3 As shown, the distance between the front and rear openings 41 of the tie rod 3 is d2, and the front-to-back distance between the opening 42 of the insulation layer 2 is d1, with d2 being greater than d1. In this arrangement, when the tie rod 3 is straightened by the inflated inflatable body 1, the tie rod 3 can exert a forward and backward force on the opening of the insulation layer 2, thereby better straightening the insulation layer 2 and achieving better thermal insulation.

[0053] According to the present invention, in a specific embodiment, the tie bars 3 are made of fabric (non-woven fabric, etc.) or TPU fabric. Preferably, to reduce the overall weight of the inflatable heat-insulating structure 100, the tie bars 3 are made of non-woven fabric. Furthermore, the tie bars 3 are made of nylon non-woven fabric with a density of 40 grams per square meter. To further reduce the overall weight of the inflatable heat-insulating structure 100, the tie bars 3 can also be made of nylon non-woven fabric with a density of 20 grams per square meter.

[0054] It should be noted that although the tie bars 3 in this embodiment are made of fabric (non-woven fabric, etc.) or TPU fabric, this does not limit the scope of protection of the present invention. Those skilled in the art will be able to use appropriate materials based on actual conditions under the technical guidance of the present invention. Non-woven fabrics and TPU fabrics are well known to those skilled in the art and will not be described in detail here.

[0055] The thermal insulation layer 2 is made of aluminized film. Aluminized film is a composite flexible packaging material formed by coating a thin layer of aluminum on a plastic film using a special process. It is well known to those skilled in the art. The thermal insulation layer 2 can also be made of other flexible thermal insulation materials besides aluminized film. Flexible thermal insulation materials are well known to those skilled in the art and will not be described in detail here.

[0056] After the inflatable body 1 is inflated, the aluminized insulation layer 2 is stretched by the tie rods 3, creating insulating air chambers between adjacent insulation layers 2 and between the insulation layer 2 and the inflatable body 1. Furthermore, the multiple insulation layers 2 reflect and isolate heat, giving the overall structure strong thermal insulation properties.

[0057] In a specific embodiment, the tie bars 3 are made of non-woven fabric. The thermal insulation layer 2 is made of an aluminum-coated film material. The distance d2 between the front and rear openings 41 of the tie bars 3 is greater than the front and rear distance d1 of the opening 42 of the thermal insulation layer 2, and the value range is approximately 3 to 6 mm, preferably 4 to 5 mm. The tie bars 3 and the thermal insulation layer 2 both have a certain degree of ductility. In this configuration, after inflation, the thermal insulation layer 2 can be kept in a straight state while ensuring that the tie bars 3 and the thermal insulation layer 2 are not torn or damaged.

[0058] In a specific embodiment, the inflatable body 1 is made of TPU fabric, that is, the first surface layer 11 and the second surface layer 12 are both made of TPU material.

[0059] In one embodiment of the present invention, a production process for an inflatable heat-insulating structural member is provided, comprising the following steps.

[0060] Step 1: Connect the first connecting portion 31 of the tie rod 3 to the second surface layer 12 of the inflatable body 1.

[0061] This embodiment uses high-frequency welding to connect the reinforcement 3 to the second surface layer 12. Specifically, the second surface layer 12 is first laid on the lower mold (hereinafter referred to as the lower mold) of the high-frequency welding device (not shown in the figure), and finally the reinforcement 3 is laid on the second surface layer 12. The upper mold of the high-frequency welding device (hereinafter referred to as the upper mold) is controlled to move downward relative to the lower mold, and while applying pressure to the second surface layer 12 and the reinforcement 3, the second surface layer 12 and the reinforcement 3 are welded together by high frequency. Figure 4As shown, at this time, the upper mold and the lower mold only weld the partial width of the tie rod 3 close to the first connecting portion 31.

[0062] The basic principles of high-frequency welding and high-frequency welding devices are well known to those skilled in the art and will not be described in detail here.

[0063] Furthermore, each reinforcement 3 may be welded to the second surface layer 12 in sequence, or a plurality of reinforcements 3 may be welded to the second surface layer 12 simultaneously by arranging a plurality of upper and lower molds side by side.

[0064] Step 2: All the multiple heat insulation layers 2 are arranged at positions close to the first connecting portion 31 (ie, close to the second surface layer 12 ) of the tie rod 3 through the clamping assembly 4 .

[0065] In this embodiment, there are four layers of thermal insulation layer 2, and each layer of thermal insulation layer 2 is provided with an opening 42 adapted to each tie rod 3. Each tie rod 3 is sequentially inserted into the opening 42 of the corresponding four layers of thermal insulation layer 2 until all four layers of thermal insulation layer 2 are located at the slot 41 (located at the end) closest to the first connecting portion 31 of the tie rod 3. Figure 1 Afterwards, all four thermal insulation layers 2 are snapped into the bayonet 41 .

[0066] By snapping all four heat-insulating layers 2 into the bottom snap-in slot 41 , more space can be reserved above the tie bars 3 , facilitating subsequent welding of the tie bars 3 and the first surface layer 11 .

[0067] Step three: connect the third connecting portion 33 of the reinforcement 3 to the first surface layer 11 .

[0068] Specifically, the reinforcement bars 3 are first laid flat on the lower mold. Then, the first surface layer 11 is laid on top of the reinforcement bars 3. Finally, the upper mold is controlled to move downward relative to the lower mold, and while applying pressure to the first surface layer 11 and the reinforcement bars 3, the first surface layer 11 and the reinforcement bars 3 are welded together using high-frequency welding.

[0069] Furthermore, each reinforcement 3 may be welded to the first surface layer 11 in sequence, or a plurality of reinforcements 3 may be welded to the first surface layer 11 simultaneously by arranging a plurality of upper and lower molds side by side.

[0070] Step 4: Move each heat insulation layer 2 onto each clamping assembly 4 so that each heat insulation layer 2 is distributed on the tie rod 3 in an intermittent manner.

[0071] Specifically, the four insulation layers 2 placed in the bottommost slots 41 in step 2 are moved into different slots 41 of the tie bars 3. At this point, the tie bars 3 are not straightened, so the insulation layers 2 can be removed from the slots 41 and then moved into different slots 41, so that the insulation layers 2 are evenly distributed in the inflatable body 1 in an interval in the vertical direction.

[0072] Step five: connect the edges of the first surface layer 11 and the second surface layer 12.

[0073] Specifically, the edge of the second surface layer 12 is first placed on the lower mold. Then, the edge of the first surface layer 11 is placed on the second surface layer 12. Finally, the upper mold is controlled to move downward relative to the lower mold, and while applying pressure to the first and second surface layers 11, 12, they are welded together using high frequency welding.

[0074] It should be noted that although high-frequency welding is used to connect the various components in this embodiment, the scope of protection of the present invention is not limited to this connection method. Those skilled in the art can use any process that can seal the connection between the tie rod 3 and the inflatable body 1, as well as the inflatable body 1 itself, based on the instructions of the present invention.

[0075] The utility model also provides a high-frequency welding process suitable for welding the reinforcement 3 made of non-woven fabric and the inflatable body 1 (the first surface layer 11 and the second surface layer 12) made of TPU fabric.

[0076] Let's use the welding between the reinforcement bars 3 and the second surface layer 12 as an example. First, the second surface layer 12 is placed on the lower mold, with its TPU layer facing upward. The reinforcement bars 3 are then placed on top of the second surface layer 12. Finally, the upper mold is controlled to move downward relative to the lower mold, applying pressure to the second surface layer 12 and the reinforcement bars 3 while simultaneously welding them together using high-frequency welding. When the upper and lower molds weld the reinforcement bars 3 to the first surface layer 11, the welding pressure between the upper and lower molds ranges from approximately 60 to 70 kg, preferably 65 kg, and the high-frequency current ranges from approximately 2 to 3 amperes. Under this setup, the TPU layer of the second surface layer 12 melts under the action of the high-frequency welding, while the non-woven reinforcement bars 3 remain unmelted. The melted TPU layer of the second surface layer 12, under the pressure of the upper and lower molds, penetrates into the reinforcement bars 3. After cooling, the TPU layer of the second surface layer 12 solidifies, thus welding to the reinforcement bars 3.

[0077] According to the present invention, the inflatable heat-insulating structure 100 can be used in products including, but not limited to, sleeping mats, insulated boxes, and cooler packs. For example, while maintaining the basic structure of each layer, the inflatable heat-insulating structure 100 can be shaped to resemble a sleeping mat, insulated box, or cooler pack. Alternatively, multiple inflatable heat-insulating structures 100 can be interconnected in a specific configuration to create the shape of a sleeping mat, insulated box, or cooler pack.
