Description

Technical Field

[0001] This utility model relates to the field of airbag deployment teaching aids, and in particular to a vehicle airbag deployment training device. Background Technology

[0002] Airbags are a crucial physical safety feature in automotive systems. Working in conjunction with seatbelts, they form a complete occupant restraint system. At the moment of impact, the airbag inflates and deploys instantly, effectively cushioning and preventing secondary collisions between occupants and hard interior components such as the steering wheel and windshield due to inertia. This significantly reduces impact injuries to critical areas like the head and chest, substantially lowering the rate of serious injury and death in accidents. While not an independent safety feature, it is an indispensable core of passive safety in modern automobiles, protecting the lives of drivers and passengers.

[0003] Airbag training tools transform abstract safety principles into intuitive, operable, and absolutely safe practical learning tools. By simulating the triggering mechanism and deployment process of a real airbag, trainees can deeply understand its working principles in a zero-risk environment.

[0004] Chinese invention patent CN118116269A discloses a vehicle airbag teaching platform. This device can be demonstrated multiple times in one lesson through a set ring array of gas generators, which improves the efficiency of the demonstration. However, the airbag needs to be fixed in the frame before it can be deployed to prevent it from shifting or deviating before it is inflated, which would affect the deployment effect. This device and existing technologies all use designs such as buckles and adhesives for fixing, which are prone to damage after long-term and repeated use, and the response speed is relatively slow. The airbag can only be deployed after the buckles are pushed open by the airbag inflation. Utility Model Content

Detailed Implementation

[0030] refer to Figures 1 to 12The vehicle airbag deployment training device shown includes a deployment component 2 for simulating the deployment of an airbag 214. The deployment component 2 is provided with a sealing plate 202 to fix the airbag 214. Both the sealing plate 202 and the airbag 214 are controlled by an inflation component 1 to quickly release the restriction of the sealing plate 202 to ensure the best deployment effect of the airbag 214 and improve the trainee's understanding of the deployment state of the airbag 214. The present invention also includes a feedback component 3, which detects the pressure generated on the driver's seat when the airbag 214 deploys, further deepening the trainee's understanding of the deployment state of the airbag 214.

[0031] refer to Figures 1 to 5 The inflation assembly 1 shown includes a base 101, and a main control panel 108 is provided on the side of the base 101. The main control panel 108 is used to control the operation of this utility model, and the pressure of the airbag 214 received by the feedback assembly 3 is displayed on the main control panel 108. A high-pressure inflation tank 102 and a mounting bracket 107 are provided on the base 101. A connecting pipe 103 and multiple sets of connecting pipes 205 are provided on the high-pressure inflation tank 102. An air inlet valve 104 is provided between the connecting pipe 103 and the high-pressure inflation tank 102. When the air inlet valve 104 is opened, the high-pressure inflation tank 102 supplies gas through the connecting pipe 103. An air inlet valve 206 is provided between the connecting pipe 205 and the high-pressure inflation tank 102. When the air inlet valve 206 is opened, the high-pressure inflation tank 102 supplies gas through the connecting pipe 205.

[0032] refer to Figures 5-10 As shown, the ejection assembly 2 includes an ejection frame 201 rotatably mounted on the mounting bracket 107. A sealing plate 202 is rotatably mounted on the ejection frame 201. An airbag 214 is disposed inside the ejection frame 201. In the initial state, the airbag 214 is folded inside the ejection frame 201. A second chamber 216 is formed between the ejection frames 201 and the ejection frame 201. An exhaust valve 203 and two sets of air inlets 206 are disposed on the side of the ejection frame 201. Both the exhaust valve 203 and the air inlets 206 are connected to the second chamber 216. When the exhaust valve 203 is opened, the gas in the second chamber 216 is discharged. The connecting pipe 105 communicates with the second chamber 216 through the air inlets 206. When the second chamber 216 is inflated, the airbag 214 is ejected from the ejection frame 201.

[0033] The upper end of the ejection frame 201 is slidably equipped with a push plate 208 and two sets of locking pins 204. The push plate 208 and the ejection frame 201 form a chamber 215. The ejection frame 201 is also equipped with an exhaust valve 205 and an air inlet 207. Both the exhaust valve 205 and the air inlet 207 are connected to the chamber 215. The connecting pipe 103 is connected to the chamber 215 through the air inlet 207. When the exhaust valve 205 is opened, the gas in the chamber 215 is discharged. When the chamber 215 is filled with air, the push plate 208 is pushed.

[0034] The ejection frame 201 is provided with a second locking hole 218, and the sealing plate 202 is provided with a first locking hole 217. When the sealing plate 202 closes the ejection frame 201 and fixes the airbag 214, the first locking hole 217 and the second locking hole 218 are coaxially aligned. A spring 213 is provided between each of the two sets of locking pins 204 and the ejection frame 201. One end of the locking pin 204 is inserted into the first locking hole 217 and the second locking hole 218 to fix the ejection frame 201 to the sealing plate 202. A baffle 212 is provided at the other end of the locking pin 204. Two sets of swing rods 209 are rotatably mounted on the upper end of the ejection frame 201. Each swing rod 209 has a set of rollers 211 rotatably mounted at both ends. One set of rollers 211 is in contact with the push plate 208, and the other set of rollers 211 is in contact with the baffle 212. When the push plate 208 moves, it pushes the two sets of swing rods 209 to rotate. The two sets of swing rods 209 push the baffle 212 to move and pull the baffle 212 out of the locking hole 1 217 and the locking hole 218, thereby releasing the fixation between the ejection frame 201 and the sealing plate 202, ensuring that the airbag 214 can be ejected quickly and without restriction.

[0035] refer to Figures 10 to 12 The feedback component 3 shown includes a bracket 303 mounted on a mounting frame 107. An adjusting column 301 is rotatably mounted on the bracket 303. A bonding plate 302 is slidably mounted inside the adjusting column 301. A spring 304 is provided between the bonding plate 302 and the adjusting column 301. Multiple pressure sensors 305 are also provided inside the adjusting column 301. The pressure sensors 305 are thin-film pressure sensors. The pressure sensors 305 are connected to the main control panel 108 and display the pressure received on the main control panel 108.

[0036] In the initial state, the airbag 214 is folded inside the ejection frame 201, and the sealing plate 202 closes the ejection frame 201. When demonstrating the ejection effect of the airbag 214, first adjust the ejection frame 201 to rotate on the mounting bracket 107 to adjust the ejection direction of the airbag 214. At the same time, adjust the position of the adjusting column 301 on the bracket 303 so that the bonding plate 302 is aligned with the ejection position of the airbag 214.

[0037] First, the high-pressure air tank 102 is started via the main control panel 108. Then, the air inlet valve 104 is opened, and the air in the high-pressure air tank 102 is quickly discharged into the chamber 215 through the connecting pipe 103. At this time, the push plate 208 is pushed by the gas, and the push plate 208 presses the roller 211 and the swing rod 209. When the swing rod 209 rotates, it presses the baffle 212. The baffle 212 drives the locking pin 204 to slide on the ejection frame 201. At this time, the locking pin 204 is pulled out from the locking hole 217 and the locking hole 218. The locking pin 204 releases the fixation between the ejection frame 201 and the sealing plate 202, and at the same time, the spring 213 is compressed.

[0038] After opening intake valve 104, quickly open both sets of intake valves 106. At this time, the air in the high-pressure inflation tank 102 quickly enters chamber 216, which inflates the airbag 214, simulating the actual deployment of the airbag 214. The airbag 214 quickly pushes open the sealing plate 202. After the airbag 214 is deployed, it fits against the bonding plate 302. The airbag 214 presses against the bonding plate 302. When the bonding plate 302 retracts into the adjusting column 301, it fits against the pressure sensor 305 and presses against the pressure sensor 305. At this time, the pressure on the bonding plate 302 is displayed on the main control panel 108. By adjusting the orientation of the adjusting column 301 and the bonding plate 302, it is easy for the trainee to understand the pressure generated by the inflation component 14 of the feedback component 3 on the driver at different angles.

[0039] After the feedback component 3 inflation component 14 is ejected, close the high-pressure inflation tank 102, air inlet valve 104 and air inlet valve 206, open exhaust valve 1 203 and exhaust valve 205 to discharge the gas in chamber 1 215 and chamber 2 216, fold the airbag 214 and put it into the ejection frame 201, and at the same time reset the sealing plate 202. After the locking hole 1 217 and locking hole 2 218 are aligned, the locking pin 204 is reset by the deformation restoring force of spring 1 213. The locking pin 204 is inserted into the locking hole 1 217 and locking hole 2 218 to complete the fixation of the ejection frame 201 and the sealing plate 202. Close exhaust valve 2 205 and exhaust valve 1 203 for the next simulation.
