[0002] The steering wheel airbag housing (also known as the steering wheel airbag module or airbag cover) is a crucial component in a vehicle's airbag system. Its primary function is to house and protect the system's key components, including the airbag inflator, sensors, and electrical connections, while also enabling rapid deployment of the airbag in the event of a collision. This component is typically located in the center of the vehicle's steering wheel, and its design and manufacturing require consideration of multiple aspects, including safety, material selection, structural design, and installation techniques.

[0003] Currently, the steering wheel airbag box needs to be able to quickly release the airbag in the event of a collision to protect the user. All steering wheel airbags on the market can do this, but since the airbag needs to be popped out accurately and quickly in the event of a collision, the installation of the steering wheel airbag boxes on the market is very cumbersome.

[0025] The surface of the docking bolt 18 is provided with a slide groove 21, and the bottom end of the inner wall of the slide groove 21 is provided with a card groove. The lower end of the card block 20 is carded with the bottom end of the inner wall of the card groove. The lifting plate 17 is located just above the damping spring. By rotating the rotary valve 13, the rotary valve 13 will drive the connecting page 14 to rotate together, so that the rotating rod 15 rotates inside the connecting plate 16, thereby moving downward. In addition, because the lifting plate 17 is fixedly connected to the lower end of the rotating rod 15, the lifting plate 17 will move toward the inside of the docking bolt 18 under the rotation of the rotary valve 13. In addition, the front side of the lifting plate 17 is fixedly connected to the limiting block 19, and the lower end of the limiting block 19 is fixedly connected to the card block 20. In this way, when the rotary valve 13 cannot be rotated, the card block 20 completes the card connection with the card groove, thereby completing its limiting and fixing work. In addition, since the connecting plates 16 are provided at both ends of the airbag box body 2, the stability of the equipment can be further improved. At the same time, the assembly process is also very convenient without too much complicated operation.

The surface of the assembly box 7 is fixedly connected to a sensing plate 9, and the sensing plate 9 is located directly above the steering wheel airbag 8. In this way, when the user is hit, the telescopic spring 6 at the lower end of the assembly box 7 will be squeezed, thereby increasing a reaction force for the upper assembly box 7. In this way, when the sensing plate 9 at the upper end of the steering wheel airbag 8 senses the impact force, it can quickly open the steering wheel airbag 8, thereby protecting the user. The entire reaction process will be very rapid, thereby ensuring the user's safety to the greatest extent.

[0030] When in use, the user needs to first connect the assembly plate 1 with the steering wheel, and at the same time complete the limit fixation of the assembly plate 1 by rotating the rotating bolt 5 at the upper end of the fixing plate 4. At this time, by rotating the rotating valve 13, the rotating valve 13 will drive the connecting page 14 to rotate together, so that the rotating rod 15 rotates inside the connecting plate 16, thereby moving downward. Since the lower end of the rotating rod 15 is fixedly connected with the lifting plate 17, the lifting plate 17 will move toward the inside of the docking bolt 18 under the rotation of the rotating valve 13. Since the front side of the lifting plate 17 is fixedly connected to the limiting block 19, the lower end of the limiting block 19 is fixedly connected with the clamping block 20. In this way, when the rotating valve 13 cannot be rotated, the clamping block 20 completes the clamping connection with the card slot, thereby completing It completes its limiting and fixing work, and since both ends of the airbag box body 2 are provided with connecting plates 16, the stability of the equipment can be further improved. At the same time, the assembly process is also very convenient, without too much complicated operation. After completing the steps, the user only needs to open the sealing cover 3, and then place the steering wheel airbag box body inside the assembly box 7, and then close the sealing cover 3. In this way, when the user is hit, the telescopic spring 6 at the lower end of the assembly box 7 will be squeezed, thereby increasing a reaction force for the upper assembly box 7, so that the sensor disk 9 at the upper end of the steering wheel airbag 8 can quickly open the steering wheel airbag 8 when it senses the impact force, thereby protecting the user. The entire reaction process will be very rapid, thereby ensuring the user's safety to the greatest extent.
