As an important component of automobile safety, airbags can ensure the life safety of drivers and passengers in the event of a safety accident. Airbags are composed of three parts: airbags, sensors, and inflation systems. They are generally distributed in the front (driver and co-driver seats), sides (front and back seats) and roof of the vehicle. Its function is to reduce the degree of injury to passengers in the event of a vehicle collision, to prevent passengers from being thrown out of their seats in dangerous situations such as secondary collisions or vehicle rollovers. Its working principle is: when the car is subjected to a certain collision force, the airbag system will trigger a chemical reaction similar to the explosion of trace explosives, and the airbag hidden in the car will be inflated and popped out instantly.

[0003] The prior art can protect the driver and passengers by using airbags, but the airbag in the steering wheel will push the airbag cover off when it pops out, causing harm to the driver and passengers, and the airbag cover may break into pieces of different sizes and fly out. Therefore, those skilled in the art provide a guide assembly for a vehicle airbag to solve the problems raised in the above background technology. Utility Model Content

[0007] As a further solution of the utility model: a connecting rope is fixedly connected to the slider, wherein the connecting rope is made of high-quality material, such as nylon, polyester fiber or polypropylene, has good strength and wear resistance, and can provide a certain elasticity, so that the connecting rope can withstand a certain tension without breaking easily.

[0008] As a further solution of the utility model: a gas generator is fixedly installed at the bottom of the protective shell, and an airbag is arranged in the placement groove, wherein the upper end of the gas generator is located inside the airbag and is closely connected to the airbag, and the device connecting the airbag and the gas generator is a specially designed ignition device.

[0009] As a further solution of the utility model: the gas generator is electrically connected to the airbag control module, and the airbag control module is electrically connected to the collision sensor, wherein when the vehicle collides, the collision sensor in the vehicle will detect the degree and direction of the collision.

[0010] As a further solution of the utility model: the lower end of the protective shell is fixedly connected with a plurality of limit pins, the outer ring of the bottom of the protective shell is fixedly connected with a mounting plate, the mounting plate is threadedly connected with a plurality of fixing screws, and one end of the connecting rope is fixedly connected to the airbag.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. After the airbag inflates rapidly, the part of the airbag inside the protective shell will protrude from the through-hole, which can stabilize the airbag in the protective shell and reduce its shaking.

[0013] 2. The airbag will lift up the first flip cover, the second flip cover, the third flip cover and the fourth flip cover, and rotate them under the airbag to prevent them from flying out and injuring the driver and passengers. The airbag is connected to the first flip cover, the second flip cover, the third flip cover and the fourth flip cover through a connecting rope to further prevent them from being lifted up.

[0014] 3. The rubber layer on the first flip cover, the second flip cover, the third flip cover and the fourth flip cover can play a buffering role, reducing the possibility of the first flip cover, the second flip cover, the third flip cover and the fourth flip cover being broken, and the rubber layer is bonded to the first flip cover, the second flip cover, the third flip cover and the fourth flip cover by glue, so it is difficult for the first flip cover, the second flip cover, the third flip cover and the fourth flip cover to separate from the rubber layer after being broken, thereby reducing the possibility of injury to the driver and passengers.
