Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive safety, and in particular to a modular, quick-installation roof curtain airbag. Background Technology
[0002] In the field of automotive safety, roof curtain airbags, as an important passive safety device, can deploy quickly in emergency situations such as vehicle collisions, providing additional head protection for occupants and effectively reducing the risk of injury. They play a key role in improving the overall safety performance of automobiles.
[0003] The current method of using roof airbags typically involves first using tools and multiple screws to install the gas generator onto the vehicle body, and then connecting the airbag to the vehicle body via a snap-fit method. Once assembled, it is put into use. However, the airbags on the current equipment are a one-piece structure. When triggered, the entire device needs to be disassembled and replaced, resulting in high replacement costs. Furthermore, the installation and disassembly process of the gas generator is cumbersome, which affects the overall replacement efficiency and makes it very inconvenient to use.
[0004] Therefore, there is a need to design a modular, quick-installation roof curtain airbag that allows for the rapid installation of gas generators and airbags for protective use, while also facilitating the removal of the gas generator and individual airbags for easy replacement after triggering, without requiring the replacement of the entire device, thus reducing costs and improving replacement efficiency. Utility Model Content
[0005] To overcome the shortcomings of current equipment where the airbag is a single unit, requiring the entire device to be disassembled and replaced after triggering, resulting in high replacement costs and cumbersome installation and removal of the gas generator, thus affecting overall replacement efficiency and causing great inconvenience, this utility model provides a modular, quick-installation roof curtain airbag that allows for rapid installation of the gas generator and airbag for protective use, while also facilitating the removal of the gas generator and individual airbags for easy replacement after triggering, eliminating the need to replace the entire device, reducing costs, and improving replacement efficiency.
[0006] The technical solution of this utility model is as follows: A modular, quick-installation roof curtain airbag includes a gas generator, an airbag, a one-way valve, a connector, a locking block, a fixing plate, a first mounting block, a second mounting block, a fixing component, and a triggering component. The airbag is connected to the lower side of the gas generator. Connectors are connected to the upper left and right sides of the airbag, and one-way valves are connected to the connectors. Locking blocks are connected to the left and right sides of the gas generator. A fixing plate is locked between the rear parts of the locking blocks. The first mounting blocks are connected to the lower left and right sides of the fixing plate, and the second mounting block is connected to the rear side of the airbag. The fixing plate is provided with a fixing component for fixing the gas generator, and a triggering component is provided in the middle of the fixing plate.
[0007] Furthermore, it is particularly preferred that the fixing assembly includes a first pressing rod, a second pressing rod, and a first spring. The first pressing rod is slidably connected to both the left and right sides of the fixing plate. The first pressing rod is engaged with the locking block on the same side. The upper part of the first pressing rod is connected to the second pressing rod. The second pressing rod is connected to the fixing plate with the first spring.
[0008] Furthermore, it is particularly preferred that the first extrusion rods are all L-shaped.
[0009] Furthermore, it is particularly preferred that the triggering component includes a pressing block, a second spring, and a limiting rod. Two limiting rods are connected to the middle of the fixing plate, and the pressing block is slidably connected between the limiting rods. The second spring is connected between each limiting rod and the pressing block.
[0010] Furthermore, it is particularly preferred that the limit rods are all T-shaped.
[0011] Furthermore, it is particularly preferred that both sides of the pressing block are beveled.
[0012] The present invention has the following advantages: 1. When a collision occurs, the airbag of the present invention inflates and deploys instantly for protection. After triggering, the first compression rod moves and engages with the locking block through the cooperation of the pressing block, the second spring, the second squeezing rod, and the first spring to achieve installation or disengagement. Then, the gas generator and the single damaged airbag can be removed. This allows for quick installation of the gas generator and airbag for protection while facilitating the removal of the gas generator and the single airbag for easy replacement after triggering. It eliminates the need to replace the entire device, reducing costs and improving replacement efficiency.
[0013] 2. This utility model splices multiple airbags by snapping another airbag onto the connector on the previous airbag and repeating the above operation. After splicing, the fixing plate is installed on the vehicle body by screws passing through the first mounting block. Then, the gas generator and airbags are installed and used. This allows for quick splicing of the device to adapt to different vehicle models, improves installation efficiency, and enhances compatibility. Attached Figure Description

Detailed Implementation
[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0021] A modular, quick-installation roof curtain, such as Figures 1-5 As shown, the device includes a gas generator 1, an airbag 2, a one-way valve 3, a connector 4, a locking block 5, a fixing plate 6, a first mounting block 7, a second mounting block 14, a fixing component, and a triggering component. The airbag 2 is connected to the lower side of the gas generator 1. The upper left and right sides of the airbag 2 are connected to the connector 4, and the one-way valve 3 is connected to each connector 4. The left and right sides of the gas generator 1 are connected to the locking blocks 5. The fixing plate 6 is locked between the rear parts of the locking blocks 5. The lower left and right sides of the fixing plate 6 are connected to the first mounting blocks 7. The rear side of the airbag 2 is connected to the second mounting block 14. The fixing plate 6 is provided with a fixing component for fixing the gas generator 1. The fixing plate 6 is provided with a triggering component in the middle.
[0022] like Figure 2 As shown, the fixing assembly includes a first pressing rod 8, a second pressing rod 9, and a first spring 10. The first pressing rod 8 is slidably connected to both the left and right sides of the fixing plate 6. The first pressing rod 8 is engaged with the locking block 5 on the same side. The first pressing rod 8 is L-shaped to facilitate positioning. The second pressing rod 9 is connected to the upper part of the first pressing rod 8. The first spring 10 is connected between the second pressing rod 9 and the fixing plate 6.
[0023] like Figure 2 As shown, the triggering assembly includes a pressing block 11, a second spring 12, and a limiting rod 13. The middle of the fixing plate 6 is connected to two limiting rods 13 on the left and right sides. The limiting rods 13 are T-shaped to facilitate guidance. The pressing block 11 is slidably connected between the limiting rods 13. The left and right sides of the pressing block 11 are both inclined to facilitate pressing and fitting. The second spring 12 is connected between the limiting rods 13 and the pressing block 11.
[0024] When the roof curtain airbag is needed, depending on the vehicle model, connect the other airbag 2 to the connector 4 on the previous airbag 2. Repeat the above operation to connect multiple airbags 2. After connection, make the fixing plate 6 and the first mounting block 7 contact with the vehicle body. Then, install the fixing plate 6 on the vehicle body by screwing it through the first mounting block 7. Next, pick up the airbag 2 with the gas generator 1 by hand, so that the locking block 5 engages with the fixing plate 6, thereby squeezing the first compression rod 8 to move, which in turn moves the second compression rod 9. The first spring 10 is compressed. When the hollow part on the locking block 5 aligns with the first compression rod 8, the first spring 10 rebounds, and the second compression rod 9 moves back to its original position. The first extrusion rod 8 is moved and reset to engage with the locking block 5 for fixation, thereby fixing the gas generator 1. Then, the other airbags 2 are picked up, so that the second mounting block 14 contacts the vehicle body, and the airbag 2 is pressed to engage with the vehicle body, thereby installing the device. This allows for quick assembly of the device to adapt to different vehicle models, improving installation efficiency and compatibility. The first extrusion rods 8 are all L-shaped. When a collision occurs, they will trigger the gas generator 1 to quickly generate a large amount of gas, which flows into the corresponding airbag 2 for inflation, and then flows through the one-way valve 3 and connector 4 into the remaining airbags 2 for instant inflation and deployment for protection. Upon triggering, pressing the pressing block 11 by hand moves it along the limiting rod 13, stretching the second spring 12, which in turn compresses the second compression rod 9, causing the first spring 10 to be compressed, thus disengaging the first compression rod 8 from the locking block 5. Then, the gas generator 1 is removed, allowing the corresponding airbag 2 to be removed. The limiting rods 13 are all T-shaped, and the pressing block 11 has beveled surfaces on both sides. Next, releasing the pressing block 11 causes the second spring 12 to rebound, resetting the pressing block 11. The first spring 10 rebounds, resetting the second compression rod 9 and the first compression rod 8. Afterward, check for any damaged airbag 2 and remove it, detaching the second mounting block 14 from the vehicle body. The gas in airbag 2 is released, causing it to contract and return to its original state. A new airbag 2 is then installed and connected to the adjacent airbag 2, allowing the second mounting block 14 to engage with the vehicle body. The new gas generator 1 is then removed, and the above operation is repeated to install and secure it, while simultaneously connecting the airbag 2 on the gas generator 1 to other airbags 2. The device is then used again, enabling the rapid installation of gas generator 1 and airbag 2 for protection, while also facilitating the removal of gas generator 1 and individual airbag 2 for easy replacement after triggering without replacing the entire device, thus reducing costs and improving replacement efficiency.
