[0014] This utility model provides a high-strength and high-toughness seamless steel tube component for automotive airbags, possessing the following characteristics:

[0015] Beneficial effects:

[0016] 1. This utility model, by providing combined end seats at the ends of the first, second, and third steel pipe components, and in conjunction with the structural design of the assembly, allows for the simple connection of the connecting pipes in the combined end seats at one end of each of the three steel pipe components to be assembled into the interior of the combined pipe on one side of the fixed seat by screwing them in. This enables the splicing and assembly of the first, second, and third steel pipe components. The above structural design provides excellent structural flexibility for the entire steel pipe structure, allowing for flexible combination and splicing of various structural components within a certain range to create different structural shapes. This satisfies different structural requirements and allows for adjustments to be made accordingly, thereby maximizing the ease of use and flexibility of the device structure.

[0017] 2. This utility model, by setting up a combination bolt, and simultaneously cooperating with a fixing seat with a docking hole and a stabilizing seat with an assembly hole, allows the first, second, and third steel pipe components to be structurally assembled using the combination parts and combination end seats by screwing the combination bolt into them. This structural design can further ensure that each structural component has sufficient structural stability and firmness after assembly. At the same time, since the first, second, and third steel pipe components are all made of austenitic stainless steel and their surfaces are all plated with nickel, the use of the above-mentioned structural materials gives the device structural components good comprehensive performance of strength and toughness, excellent processability, weldability, and corrosion resistance. In addition, cold working hardening (cold drawing) can significantly improve the strength of each structural component to meet the usage requirements and ensure sufficient service life.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1 to 6 As shown, a high-strength and tough seamless steel tube component for automotive airbags includes a first steel tube component 1 and an assembly 2. The first steel tube component 1 has assemblies 2 installed at both ends, and a second steel tube component 3 and a third steel tube component 4 are respectively assembled and installed at both ends of the first steel tube component 1 via the assemblies 2. Combination bolts 5 are installed at the joints between the first steel tube component 1, the assembly 2, the second steel tube component 3, and the third steel tube component 4. A combination end seat 6 is provided at the combined ends of the first steel tube component 1, the second steel tube component 3, and the third steel tube component 4. The assembly 2 includes a fixing seat 201, a combination tube 202, and mating holes 203. Combination tubes 202 are provided on both sides of the fixing seat 201, and mating holes 203 are provided at the four opposite corners of the fixing seat 201. The fixing seat 201 and the combination tube 202... The components are arranged as a single unit. The combined end seat 6 includes a stabilizing seat 601, a connecting pipe 602, and an assembly hole 603. The connecting pipe 602 is provided on one side of the stabilizing seat 601, and the assembly hole 603 is provided at each of the four diagonal corners of the stabilizing seat 601. The stabilizing seat 601 and the connecting pipe 602 are arranged as a single unit. The connecting pipe 602 and the combined pipe 202 are threaded together. The combined bolts 5 are threaded together with the connecting holes 203 and the assembly holes 603. The connecting pipe 602 of each of the first steel pipe component 1, the second steel pipe component 3, and the third steel pipe component 4 to be combined is screwed into the combined pipe 202 on one side of the fixed seat 201 by screwing. This realizes the splicing and combination of the first steel pipe component 1, the combined component 2, the second steel pipe component 3, and the third steel pipe component 4.

[0027] like Figures 1 to 6 As shown, the first steel pipe component 1 is arranged in a "I" shape, the second steel pipe component 3 is arranged in an "L" shape, and the third steel pipe component 4 is arranged in a "T" shape. All three components are made of austenitic stainless steel and are coated with a nickel layer. The two ends of the first steel pipe component 1, the two ends of the second steel pipe component 3, and the three combined ends of the third steel pipe component 4 are connected by laser welding. The first steel pipe component 1, the second steel pipe component 3, and the third steel pipe component 4 have the same diameter. The first steel pipe component 1, the assembly 2, the second steel pipe component 3, the third steel pipe component 4, the assembly bolt 5, and the assembly end seat 6 are connected and assembled with each other using a detachable structure. The assembly 2 and the assembly end seat 6 are both made of high-strength low-alloy steel. By screwing the assembly bolt 5 into them, the first steel pipe component 1, the second steel pipe component 3, and the third steel pipe component 4 are structurally assembled using the assembly 2 and the assembly end seat 6.

[0028] In summary, as Figures 1 to 4 As shown, the high-strength and tough seamless steel tube component used in this automotive airbag is first assembled by selecting an appropriate number of the first steel tube component 1, the second steel tube component 3, and the third steel tube component 4 connected to the combined end seat 6, and then combining them with an appropriate number of assemblies 2. Simply screw the connecting pipe 602 at one end of the stabilizing seat 601 into the combined pipe 202 on one side of the fixing seat 201, and then horizontally screw the combination bolt 5 into the mating hole 203 and the assembly hole 603. This achieves a quick and stable structural assembly. The first steel tube component 1, the second steel tube component 3, and the third steel tube component 4 can be assembled one by one as needed until the operation is complete.
