Description
Technical Field
[0001] This utility model relates to the field of police equipment, and in particular to an integrated structure of multiple gas generators. Background Technology
[0002] When bomb disposal officers are performing high-risk missions, they often fall due to external forces. Such falls can not only directly cause physical injuries such as fractures and traumatic brain injury, but also pose a risk of secondary explosions due to equipment damage or malfunction. In existing technologies, inflatable fall protection components can sense the fall and inflate before the user hits the ground, providing cushioning contact between the user and the ground and reducing spinal and head injuries from backward falls.
[0003] However, such protective equipment typically relies on airbag deployment for support, and each airbag needs to be re-inflated after deployment to be used again, making rapid reuse impossible. Therefore, there is an urgent need to design a device that can be reused without requiring lengthy maintenance. Utility Model Content

[0021] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
[0022] As one embodiment, an integrated structure of multiple gas generators is proposed. This integrated structure of multiple gas generators, such as... Figure 1-4 As shown, it includes: a metal top cover 3, a gas generator 7, and a metal bottom shell 9; the top of the metal top cover 3 is connected to an electrical wiring 1, one end of which is connected to a power supply device, and the other end extends into the metal top cover 3 and is connected to a gas generator signal line 5. The gas generator signal line 5 is connected to the wiring terminal on the top of the gas generator 7. The electrical wiring is used to supply power to the gas generator 7 so that the gas generator 7 can exhaust gas; the metal bottom shell 9 is nested with a gas generator bracket 8, which has several gas generator mounting holes 11. The gas generator 7 is installed in the gas generator mounting holes 11. A gas generator cover plate 6 is installed and fixed on the top of the gas generator bracket 8. The gas generator 7 is fixed in the space formed by the gas generator bracket 8 and the gas generator cover plate 6. The metal top cover 3 and the metal bottom shell 9 are fixed by fastening screws 2; the metal bottom shell 9 includes an exhaust hole 10, which is located at the bottom of the metal bottom shell 9. This integrated structure of multiple gas generators has a high degree of integration, a compact spatial arrangement, and is miniaturized and easy to carry.
[0023] like Figure 1 and Figure 2 As shown, the metal upper cover 3 and the metal lower shell 9 have corresponding openings at their four corners. The top of the metal lower shell 9 has an annular groove, in which a sealing ring 4 is installed. A fastening screw 2 is fixed through the opening. When the metal upper cover 3 and the metal lower shell 9 are fastened together and tightened with the fastening screw 2, the sealing ring 4 is compressed between the annular groove and the metal upper cover 3 to achieve a sealing function.
[0024] like Figures 2-3bAs shown, the gas generator bracket 8 has a ribbed gas generator limiting structure 15 on the inner wall of the gas generator mounting hole 11, and a blocking structure 13 at the bottom of the gas generator mounting hole 11; the gas generator cover plate 6 has holes corresponding to the gas generator mounting hole 11, and the gas generator 7 is installed in the space formed by the holes in the gas generator cover plate 6 and the gas generator mounting hole 11; the top of the gas generator bracket 8 and the gas generator cover plate 6 have corresponding openings, and the gas generator bracket 8 and the gas generator cover plate 6 are fastened and fixed by screws in the openings; the ribbed gas generator limiting structure 15 forms an initial gas generator limit for the gas generator 7. The gas generator 7 is fixed in the first step, and then fixed in the second step by the gas generator bracket 8 and the gas generator cover plate 6. The gas generator cover plate 6 has a groove on its edge and is fixed to the top of the metal lower shell 9. The gas generator cover plate 6 and the metal lower shell 9 are fastened together by the metal upper cover 3 and the metal lower shell 9 and tightened with fastening screws 2 to completely fix the gas generator cover plate 6 and the metal lower shell 9, thus forming a third fixation. The gas generator 7 is completely fixed in the space formed by the metal upper cover 3 and the metal lower shell 9. The ribbed gas generator limiting structure 15 ensures that the position of the gas generator 7 is accurate and does not shake to the maximum extent without interfering with the normal overflow of the gas discharged from the gas generator 7.
[0025] like Figures 2-3b As shown, the gas generator bracket 8 includes a barrier structure 13. The gas generator bracket 8 is made of aluminum alloy, which has good rigidity and load-bearing capacity, effectively supporting the gas generator 7. The barrier structure 13 is located at the bottom of the gas generator bracket 8. The barrier structure 13 has a set of overflow holes 12 corresponding to the position of a single gas generator mounting hole 11. The barrier structure 13 has an array of overflow holes 12. The gas generator mounting holes 11 are staggered within the gas generator bracket 8, and adjacent gas generator mounting holes 11 are provided with anti-interference isolation 14. The gas generator 7 has an aluminum shell. The barrier structure 13 is used to prevent the aluminum shell from falling off after the gas generator 7 releases gas. The overflow holes 12 are used to overflow the air discharged by the gas generator 7. The anti-interference isolation 14 is used to prevent the used gas generator 7 from interfering with or damaging other unused gas generators 7.
[0026] like Figures 1-3b As shown, the vent 10 includes a central vent and side vents. The central vent extends into the inner wall of the bottom of the lower metal shell 9. The gas generator bracket 8 is mounted on top of the central vent, and a gap is left between the gas generator bracket 8 and the bottom of the lower metal shell 9. The vents are used to discharge the gas generated by the gas generator 7. Figure 4 As shown, the gas generated by the gas generator 7 enters the air outlet 10 from top to bottom along the direction of the arrow, and the air outlet 10 is connected to the pneumatic working device.
