[0002] At present, the transportation of shelters is strictly limited by the width and height of vehicles, which makes the shelters provide less space and difficult to deploy activities. In the expandable shelters, the existing technology mostly adopts the expandable wall panel structure, which has high rigidity and does not meet the requirements of lightweight carrying; the tent-type structure is completely adopted, and the cabin body has poor stability and is easy to deform. Therefore, expandable cabins combining flexible air membranes with shelter wall panels are increasingly used. With the emergence of new expandable shelters, the requirements for air membrane structures of expandable shelters with different structures are different. The top / double-side three-expandable shelter is suitable for medical and military use because of its large operating space and flexible deployment. However, there are fewer air membrane structures suitable for the top / double-side three-expandable shelters.

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0037] The utility model discloses an air film cabin, such as Figure 1 As shown, the shelter is a shelter that can be expanded on the top / left and right sides, and includes an air membrane 1.

[0038] The cabin is a top / side three-expandable cabin, the top is lifted and expanded by a cross-slant rod mechanism, and the side panels 23 on both sides are rotated and unfolded by telescopic rods, and the unfolded side panels 23 serve as the bottom plate of the expansion cabin. After being inflated, the air film 1 covers the upper part of the cabin body 2 and is used as the top and side wall of the expansion cabin.

[0039] Air film 1 is TPU brushed film, which has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, light weight, non-toxicity, corrosion resistance, radiation resistance, etc., flame retardancy B1 level, pressure resistance>15Psi, unit weight ≤2000g / m 2 The working temperature is -50℃~+60℃, and it can construct an air membrane structure with high structural stability, strong load supporting capacity, good thermal insulation, vibration absorption and load adaptability.

[0040] like Figure 2 As shown, the air film 1 includes a first air film wall 101 and a second air film wall 102. The first air film wall 101 is located at the front and rear ends, and the second air film wall 102 is located at the left and right sides. In order to ensure the integrity of the air film 1, the air film 1 is welded by the first air film wall 101 and the second air film wall 102. The first air film wall 101 is a sheet-like U-shaped structure with an opening. The upper part is connected to the top frame 211 of the square cabin, and the lower opening is connected to the front plate frame 221 and the rear plate frame. After inflation, it serves as the front and rear walls of the expansion cabin; the second air film wall 102 is an L-shaped structure, which is fixedly connected to the top plate frame 211 and the side plate 23. After inflation, it serves as the top and left and right side walls of the expansion cabin.

[0041] like Figure 3As shown, the top of the air membrane 1 is opened as a whole and is fixed to the top plate frame 211 under the cabin top plate 21; the bottom of the air membrane 1 is fixed to the bottom plate and side plate 23 of the cabin; the U-shaped opening of the air membrane 1 is fixed to the front plate frame 221 and the rear plate frame of the cabin, and the bottom of the air membrane 1 is fixed to the edge of the side plate 23.

[0042] After inflation, the first air film wall can serve as the front wall and the rear wall of the expansion cabin, and the second air film wall can serve as the top and the side wall of the expansion cabin.

[0043] The air film 1 is an important part of the expansion cabin. The sealing performance of the connection between the air film 1 and the cabin body 2 determines the sealing performance of the entire expansion cabin. The air film 1 is a flexible body, and the top plate frame 211 is a rigid body. Figure 4 As shown, when the air membrane 1 is connected to the top plate frame 211, this embodiment adopts a method of multiple fixing and sealing of the air membrane 1 on the top square steel 2111 of the frame. When the top opening of the air membrane 1 is connected to the top frame 211 of the cabin, the air membrane 1 is fixed on the four top square steels 2111 of the frame, thereby being fixed to the entire top frame 211. Specifically, the top square steel 2111 includes a first adhesive surface, a second adhesive surface and a third adhesive surface, and the second adhesive surface is located between the first adhesive surface and the third adhesive surface; first, the upper and lower layers of the air membrane 1 are peeled off from the main body of the air membrane 1 at the edge of the air membrane 1, and the length of the lower layer at the edge of the air membrane 1 is greater than the upper and middle layers. The upper layer peeled off from the edge of the air membrane 1 is completely bonded to the first adhesive surface. It should be noted that in order to make the connection not easy to detach, the bonding height of the upper layer of the air membrane 1 is to the middle and upper part of the first adhesive surface, that is, after bonding, the height of the upper layer of the air membrane 1 is located in the middle and upper part of the first adhesive surface. Furthermore, the lower layer of the air film peeled off from the edge of the air film 1 is completely adhered to the second adhesive surface and the third adhesive surface, and the end of the lower layer of the air film is bonded to the upper middle part of the third adhesive surface, which is the same as the bonding height of the upper layer of the air film 1 to the first adhesive surface.

[0044] In order to strengthen the fixation between the air film 1 and the top plate square steel 2111 to prevent the air film 1 from being separated from the surface of the top plate square steel 2111, in addition to bonding, the air film 1 and the top plate square steel 2111 are fixed with multiple bolts on the side where the lower layer of the air film 1 is bonded to the top plate square steel 2111. Furthermore, the bolts are glued around with silicone to prevent the addition of bolts from damaging the sealing between the air film 1 and the top plate square steel 201.

[0045] Compared with the prior art, in the fixation and sealing of the flexible body of the air membrane 1 and the top plate square steel 2111, the upper and lower layers of the air membrane 1 are separated, and the upper layer is bonded to the first bonding surface of the top plate square steel 2111, which is the first level of fixation and sealing; the lower layer is bonded to the second and third bonding surfaces of the top plate square steel 2111, which is the second level of fixation and sealing; the air membrane 1 is fixed to the third bonding surface of the top plate square steel 2111 with bolts, and the bolts are sealed around with silicone, which is the third level of fixation and sealing. After multiple layers of fixation and sealing, the air membrane 1 and the top plate square steel 2111 of the frame are tightly fitted, ensuring high air tightness between the air membrane 1 and the cabin body 2.

[0046] When the air membrane 1 is fixed to the edges of the front plate 22, the rear plate and the side plate 23 of the cabin, a sealing aluminum profile is used for sealing connection, and a silicone plate is provided at the profile crimping position for sealing.

[0047] Compared with the prior art, the air membrane 1 in this embodiment is a whole, rather than the zipper stitching or the shielding cloth separated from the main body of the air membrane 1 in the prior art, which ensures the integrity of the structure of the air membrane 1. At the same time, the top of the air membrane 1 is sealed with multiple seals, and the bottom of the air membrane 1 and the square cabin wall are sealed with sealed aluminum profiles and silicone plates to ensure the air tightness of the cabin.

[0048] The air film 1 is a double-layer airbag structure, which can be inflated in the middle. The height of all inflation holes is 300mm from the bottom plate. Figure 5 As shown, the outer side of the first air film wall 101 is provided with first inflation holes 1011, the number of which is two and the distance from the adjacent side is 400mm; Figure 6 As shown, the outer side surface of the second air membrane 102 is provided with two second inflation holes 1021 , which are 1000 mm away from the adjacent edge.

[0049] When inflating, the air pump interface is connected to the inflation hole of the air membrane 1, and the air pump is started to inflate the first air membrane 101 and the second air membrane 102 in sequence until the air membrane 1 is fully deployed.

[0050] When deflation occurs, the air pump interface is connected to the air filling and deflation interface of the air membrane 1, and the air pump is started to deflate the second air membrane 102 and the first air membrane 101 in sequence until the air membrane 1 collapses completely.

[0051] When the shelter is folded, the air film 1 is stored inside the shelter wall plate. When the shelter is expanded, the lifting mechanism lifts the top of the upper frame upward, and the air film 1 is unfolded upward; after the top of the shelter is lifted into place, the side plate 23 rotates and expands outward, and the bottom of the air film 1 is unfolded outward accordingly.

[0052] Before inflation, since the top of the air film 1 is fixed to the top plate frame 211, when the top plate 21 is lifted upward, the top plate frame 211 and the top of the air film 1 rise with it. When the side panels 23 are expanded, the bottom of the air film 1 and the part connected and fixed to the edge of the side panels 23 are expanded outward with the side panels 23, driving the edge of the air film 1 to move outward. At this time, the air film 1 is in a collapsed state. After inflation, the air film 1 stands up, and the parts connected to the bottom plate, side panels 23 and the upper parts of the front panel 22 and the rear panel serve as the side walls of the expansion cabin; the top of the air film 1 covers the upper part of the square cabin body 2 as the top of the expansion cabin. The square cabin expands the space on the top and both sides at the same time. Since the air film 1 is a whole, there is no need to use a shielding cloth on the top, and there is no need to sew the front and back with zippers, etc., to ensure the sealing of the entire square cabin.

[0053] Furthermore, if Figure 7 As shown, a buckle 3 is provided on the upper part of the air film 1 for hoisting the air film 1 and for windproof hook. Figure 8 As shown, in order to prevent the top plate from falling down and pressing the film when the air is released and the film is collected, an elastic tightening belt 4 is provided at the inner upper part of the first air membrane 101 and the second air membrane 102 .

[0054] Furthermore, in order to improve the wear resistance of the air film 1 , a wear-resistant sheet is pasted on the edge of the air film 1 .

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
