[0002] With the rapid development of the automotive industry, automotive safety performance has received increasing attention. As an important part of automotive side collision protection, the rapid response and effective inflation of side air curtains are crucial for protecting passengers.

[0003] Existing automotive side air curtain devices usually need to rely on mounting brackets to install the side air curtains. The installation process is relatively complex, not convenient for maintenance, and after the side air curtain device is triggered, due to design limitations, it may not reach the ideal inflation state in a short time, thus affecting its protection effect.

[0004] Therefore, there is a need to develop a side air curtain device that is easy to install and maintain, can be collided in a short time, and improves the protection effect of the side air curtain. Summary of the Utility Model

[0005] In order to overcome the shortcomings of existing automotive side air curtain devices, such as relatively complex installation process, inconvenient maintenance, and the inability to reach the ideal inflation state in a short time after being triggered, which affects their protection effect, the utility model provides a side air curtain device that is easy to install and maintain, can be collided in a short time, and improves the protection effect of the side air curtain.

[0006] The technical solution is as follows: A side air curtain device includes a housing, an ignition sheet, gunpowder, a pressure chamber, a first fixing bracket, a soft sleeve, a second fixing bracket, a first airbag, a magic tape, a connecting plate, a fixing rope, and a second airbag. The ignition sheet is connected to the front of the housing, the gunpowder is filled in the front of the housing, the pressure chamber is opened at the rear of the housing, the first fixing bracket is connected to the outside of the front of the housing, the first airbag is connected to the rear of the housing through the soft sleeve, the second fixing bracket is connected to the outside of the soft sleeve, the fixing rope is connected to the rear of the first airbag, the second airbag is connected to the right side of the soft sleeve, the magic tape is also sleeved on the outside of the second airbag, the connecting plates are connected to the magic tapes, and the fixing rope is connected to the front of the second airbag.

[0007] Preferably, the pressure chamber pre-stores gas.

[0008] Preferably, the gunpowder is a special material.

[0009] Preferably, the pressure chamber is made of soft shell plastic material.

[0010] Preferably, the fixing ropes are all provided with loops.

[0011] Preferably, the soft sleeve is made of elastic rubber material with good sealing performance.

[0012] Advantages of the utility model: The utility model is fixed by the first fixing frame and the second fixing frame, and then the first airbag and the second airbag are fixed by the fixing rope and the connecting plate. After ignition, a large amount of gas generated by the explosion of gunpowder and the gas pre-stored in the air pressure chamber cause the first airbag and the second airbag to expand rapidly, achieving the effects of being convenient for installation and maintenance, and being able to collide in a short time, improving the protection effect of the side air curtain. Description of the Drawings

[0013] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.

[0014] Figure 2 It is a partial three-dimensional structural sectional view of the utility model.

[0015] Reference numerals in the drawings: 1 - housing, 10 - ignition piece, 11 - gunpowder, 12 - air pressure chamber, 2 - first fixing frame, 3 - soft sleeve, 4 - second fixing frame, 5 - first airbag, 6 - magic tape, 7 - connecting plate, 8 - fixing rope, 9 - second airbag. Detailed Embodiment

[0016] The following further describes the utility model in conjunction with the drawings and embodiments.

[0017] A side air curtain device, as Figure 1 and Figure 2 shown, includes a housing 1, an ignition piece 10, gunpowder 11, an air pressure chamber 12, a first fixing frame 2, a soft sleeve 3, a second fixing frame 4, a first airbag 5, magic tape 6, a connecting plate 7, a fixing rope 8 and a second airbag 9. The front part of the housing 1 is connected with the ignition piece 10, the front part of the housing 1 is filled with gunpowder 11. The gunpowder 11 is made of special material and can generate a large amount of gas when exploding. The rear part of the housing 1 is provided with an air pressure chamber 12. The air pressure chamber 12 is made of soft-shell plastic material and is easy to break under impact. The air pressure chamber 12 pre-stores gas. The outer side of the front part of the housing 1 is connected with the first fixing frame 2. The first airbag 5 is connected to the rear side of the housing 1 through the soft sleeve 3. The second fixing frame 4 is connected to the outer side of the soft sleeve 3. The soft sleeve 3 is made of elastic rubber material with good sealing performance. The fixing rope 8 is connected to the rear part of the first airbag 5. The second airbag 9 is connected to the right side of the soft sleeve 3. Magic tape 6 is also sleeved on the outer side of the second airbag 9. Connecting plates 7 are connected to the magic tapes 6. The fixing rope 8 is connected to the front side of the second airbag 9. Loops are provided on the fixing ropes 8 for easy fixing.
