Description

Technical Field

[0001] This utility model relates to the field of airbag safety technology, and in particular to a safety structure for airbag products. Background Technology

[0002] Some large inflatable airbag products are mainly used in commercial, industrial and special environments, and can provide stronger support, protection or protection effects. For example, some inflatable tents, inflatable exhibition halls, inflatable domes, inflatable garages / parking sheds, etc. are suitable for on-site use and can be quickly set up and applied.

[0003] For a long time, the safety venting structure used in inflatable airbag products has been a single ball valve or diaphragm solenoid valve arranged in the piping system, but these two structures each have their own advantages and disadvantages:

[0004] The advantages of diaphragm solenoid valves are good resistance to low temperatures and they are not easy to freeze; however, the disadvantage is that the exhaust volume is small. When the ambient temperature rises, the exhaust volume is prone to insufficient, causing the airbag body to be under high pressure for a long time, which seriously affects the reliability and life of the airbag body.

[0005] The advantage of ball valves is their large exhaust volume; however, the disadvantage is that when the ambient temperature is below -10℃, the ball valve core is prone to freezing, which can lead to failure to exhaust air and close the valve, resulting in overall failure.

[0006] Given that the safety structure of existing inflatable airbag products cannot meet the actual needs of use, there is an urgent need for new technologies to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a safety structure for airbag products, solving the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety structure for an airbag product, including a main inflation system pipeline, one end of which is connected to an inflation cabinet that can provide an air source, and multiple inflation branch pipes branching off from the main inflation system pipeline, the other ends of which are connected to the airbag body.

[0009] Each of the aforementioned inflation branch pipes is equipped with a ball valve and a diaphragm solenoid valve.

[0010] It also includes a control cabinet, which is connected to the gas filling cabinet, ball valve and diaphragm solenoid valve via wires for controlling their operation.

[0011] As a further technical solution of this utility model, the air-filled cabinet has two fans fixed inside by a bracket. The air inlet end of each of the two fans is provided with a filter cartridge, and the air outlet end of each of the two fans is connected to an air outlet pipe. The other end of the two air outlet pipes is connected to a common junction box.

[0012] As a further technical solution of this utility model, the manifold is provided with an inflation outlet, and the main pipeline of the inflation system is connected to the inflation outlet of the manifold through a detachable pipe.

[0013] As a further technical solution of this utility model, a first tee pipe is provided between the main pipeline of the inflation system and the inflation branch pipe, and the inflation branch pipe is connected to the main pipeline of the inflation system through the first tee pipe.

[0014] As a further technical solution of this utility model, the ball valve is installed on and connected to the inflation branch pipe, a second three-way pipe is installed between the diaphragm solenoid valve and the inflation branch pipe, the diaphragm solenoid valve is connected to the inflation branch pipe through the second three-way pipe, and the other end of the diaphragm solenoid valve is connected to an exhaust pipe.

[0015] This utility model provides a safety structure for airbag products, which has the following advantages compared with the prior art:

[0016] This invention incorporates two types of electric valves in the inflation system pipeline. Compared with the original single-structure electric valve, it offers better environmental adaptability and higher safety. Through the coordinated control of the inflation cabinet, ball valve, and diaphragm solenoid valve by the control cabinet, the venting method can be flexibly selected according to the ambient temperature and the pressure inside the airbag, effectively maintaining stable airbag pressure, extending the service life of the airbag, and is highly practical and easy to implement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 This utility model provides a safety structure technical solution for airbag products: a safety structure for airbag products includes an inflation system main pipeline 2, one end of which is connected to an inflation cabinet 1 that provides an air source. Inside the inflation cabinet 1, two fans 11 are fixed by a bracket. The air inlet end of each of the two fans 11 is equipped with a filter cartridge to filter the incoming air. The air outlet end of each of the two fans 11 is connected to an air outlet pipe 12. The other end of the two air outlet pipes 12 is connected to a manifold box 13. The manifold box 13 is equipped with an inflation outlet. The inflation system main pipeline 2 and the inflation outlet of the manifold box 13 are connected by a detachable pipe. A pressure relief valve can be designed on the manifold box 13. When the airbag body 7 deflates, if the pressure on the inflation system main pipeline 2 is too high and flows back to the manifold box 13, the pressure can be relieved by the pressure relief valve.

[0022] The main inflation system 2 branches into multiple inflation branch pipes 6. A first tee pipe 3 is provided between the main inflation system 2 and the inflation branch pipes 6, and the inflation branch pipes 6 are connected to the main inflation system 2 through the first tee pipe 3. The other ends of the multiple inflation branch pipes 6 are connected to the airbag body 7. A certain number of inflation branch pipes 6, ball valves 4, and diaphragm solenoid valves 5 can be configured according to the volume of the airbag body 7.

[0023] Each inflation branch pipe 6 is equipped with a ball valve 4 and a diaphragm solenoid valve 5. The ball valve 4 is installed on the inflation branch pipe 6 and connected to it. A second three-way pipe 61 is installed between the diaphragm solenoid valve 5 and the inflation branch pipe 6. The diaphragm solenoid valve 5 is connected to the inflation branch pipe 6 through the second three-way pipe 61. The other end of the diaphragm solenoid valve 5 is connected to an exhaust pipe.

[0024] It also includes a control cabinet 8, which is connected to the inflation cabinet 1, ball valve 4 and diaphragm solenoid valve 5 via wires to control their operation. The control cabinet 8 and the inflation cabinet 1 are connected together via a communication line, and then the control cabinet 8 interacts with the inflation cabinet 1 by collecting feedback signals to ensure that the pressure of the entire airbag body 7 is maintained within the normal range, thus ensuring the safety and reliability of the airbag body 7.

[0025] The working principle of this utility model is as follows: When in use, the control cabinet 8 controls the operation of the inflation cabinet 1. The fan 11 draws in air filtered by the filter cartridge, and sends it into the airbag body 7 through the air outlet pipe 12, the manifold box 13, the main inflation system pipeline 2 and the inflation branch pipe 6 to realize inflation.

[0026] When the ambient temperature rises, to prevent the airbag body 7 from being under high pressure for a long time, it is necessary to vent air. The control cabinet 8 will control the ball valve 4 and / or the diaphragm solenoid valve 5 to open based on the airbag internal pressure and ambient temperature signals (pressure can be detected by adding a pressure sensor or pressure gauge to the airbag body 7, and ambient temperature can be monitored by a temperature sensor).

[0027] In low-temperature environments, the diaphragm solenoid valve 5 can be opened to release air, preventing the ball valve 4 from freezing.

[0028] If the air volume is high or a large exhaust volume is required, the ball valve 4 can be opened to exhaust the air and ensure sufficient exhaust volume.

[0029] Through the coordinated work of the two, the pressure inside the airbag body 7 is kept within the normal range, improving safety and reliability.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
