[0038] The side frame airbag includes a plurality of support airbags distributed vertically or obliquely.

[0039] Furthermore, a cross-shaped support airbag is arranged inside the quadrilateral frame airbag of the top frame airbag and the bottom frame airbag, and the four corners of the cross-shaped airbag are respectively connected to the four corners of the corresponding upper frame airbag or the corresponding lower frame airbag, and the four corners of the top frame airbag and the bottom frame airbag are each provided with a multiple intersecting structure airbag, and the top frame airbag and the bottom frame airbag are respectively connected to the side frame airbag through the multiple intersecting structure airbags, such as Figure 5 As shown, the multiple intersecting structure airbag includes a main airbag 2-1, a first main airbag 2-2 and a second main airbag 2-3, and the first main airbag 2-2 and the second main airbag 2-3 are connected to the same cross-sectional position of the main airbag 2-1; wherein the multiple intersecting structure airbag is connected by multiple diameter airbags at will, and is integrally formed, which can meet the design and processing of most structural airbags; at the same time, the multi-bag intersecting structure can reduce the amount of materials, reduce the weight and packaging volume of the structural airbag; in addition, through the intersecting of multiple bags, the problem of local structural stress concentration is solved, the strength of the structural airbag is improved, and the overall strength and installation accuracy of the inflation at this place can be strengthened, and the reliability of the product can be improved, which can be widely promoted and applied to other structural airbags and other ship and bag-type bearing structures, and can be mass-produced and equipped for use by troops, with considerable economic benefits. At the same time, it can be promoted to other civilian airbag products, expand military-civilian integration, and has broad application prospects.

The four oblique straight section airbags are distributed circumferentially along the hollow shaft seat. The two ends of the oblique straight section airbags are respectively connected to the hollow shaft seat and the corresponding multiple intersecting structure airbags; the hollow shaft seat 2-9 is used to install the support column.

[0043] A method for forming an airbag using the multiple intersecting structures described above, such as Figure 6 As shown, the following steps are included: Step 1, connecting the inner part of one end of the first main body panel 2-5 and the inner part of one end of the second main body panel 2-6 by bonding or heat sealing; Step 2, fix the outer part of one end of the first main body panel 2-5 and the outer part of one end of the second main body panel 2-6 after bonding or heat sealing to the main airbag panel 2-4 by ultrasonic welding or heat sealing, and heat seal or bond the first main body panel 2-5, the second main body panel 2-6 and the main airbag panel 2-4 at the ultrasonic welding or heat sealing position, so that the front and back sides of the ultrasonic welding or heat sealing position are covered with adhesive strips; Step 3, the first main body piece 2-5, the second main body piece 2-6 and the main airbag piece 2-4 are respectively assembled by heat sealing to form the first main body airbag 2-2, the second main body airbag 2-3 and the main body airbag 2-1 respectively.

[0044] Furthermore, the first main body panel, the second main body panel and the main airbag panel are annular panels.

[0045] Furthermore, the first main body panel, the second main body panel and the main airbag panel are made of the same material; and the rubber strip is made of the same material as the main airbag panel.

[0046] Further, in the step 1, one end of the first main body panel 2-5 is bonded or heat-sealed to one end of the second main body panel 2-6 through the outer rubber strip 2-7 and the inner rubber strip 2-8; the inner rubber strip 2-8 and the outer rubber strip 2-7 are respectively arranged on the inner side and the outer side of the bonding or heat-sealing connection between the first main body panel 2-5 and the second main body panel 2-6; In the step 2, the connection between the main airbag panel 2-4 and the first main panel 2-5 and the second main panel 2-6 is covered with an outer rubber strip 2-7 and an inner rubber strip 2-8 in sequence.

[0047] In this method, the first main body panel 2-5, the second main body panel 2-6, the inner rubber strip 2-8 and the outer rubber strip 2-7 can be bonded, heat-sealed, ultrasonically welded or heat-sealed to the main airbag material carrier sheet 2-4.

[0048] Furthermore, the load-bearing high-precision flexible structural airbag also includes a packaging component, which is used to store the load-bearing high-precision flexible structural airbag that is folded and arranged on the supporting column after the carrying equipment and the structural airbag are deflated; the packaging component protects the structural airbag and the carried equipment; the inflation system 4 is arranged on the supporting column 1.

[0049] Furthermore, the onboard equipment includes any one or any combination of antennas, radars, beacons and sonars.

[0050] Furthermore, the structural airbag is made of lightweight textile material, which effectively reduces product weight and volume; and maintains structural accuracy through airbag internal pressure control technology and regional load-bearing and regional load-sharing technology.

[0051] The working principle of the present invention is as follows: Figure 1 As shown, the onboard equipment 3 (including antenna, radar, beacon and sonar, etc.) is installed on the structural airbag 2 through the connecting assembly 7, and the structural airbag 2 is fixedly connected to the supporting column 1. In the non-working state, the package is folded and stored in the packaging assembly, and the traction assembly 6 is in a relaxed state. After the traction assembly is folded in a Z shape, it is tightened with a fixed rope to avoid unnecessary entanglement of the traction assembly 6 with the structural airbag 2 during inflation. In the non-working state, the airbag assembly 2 is close to the center position of the supporting column 1, which is convenient for achieving a smaller packaging volume.

[0052] When the airbag starts to work, the inflation system 4 is activated by hand pulling or electric ignition, and quickly inflates the structural airbag 2 to the specified design shape, the package component is thrown out, and the traction component 6 is tensioned. Through the inflation of the structural airbag 2, the connecting component 7 drives the carrying device 3 to move in the deployment direction of the structural airbag 2. When the structural airbag 2 is fully inflated and deployed, the carrying device 3 is deployed to the working state under the tension of the inflated structural airbag 2, and is continuously kept in a fixed position to ensure that the carrying device 3 is within the specified structural accuracy range.

[0053] After the structural airbag 2 is loaded, the traction mechanism 6 ensures the axial structural accuracy through axial tension, so that the mounted device 3 is within the specified structural accuracy range. The airbag assembly 2 ensures the structural rigidity through the working pressure of the airbag, so that the mounted device 3 is within the specified structural accuracy range.

[0054] In summary, the present invention relates to a high-precision flexible structure airbag that can carry heavy loads. The use of flexible structure airbags can replace metal support parts of equipment such as antennas, radars, beacons and sonars, effectively reducing the weight and packaging volume of the system, and can achieve one-button automatic molding, and achieve rapid deployment by one person. This technology can be extended to other structural parts that have requirements on weight and volume; through airbag internal pressure control technology and regional load-bearing and regional load-sharing technology, the problems of large weight and large packaging volume can be solved, and the needs of rapid deployment by one person can be met.
