How do airbags protect car owners with such great power?

After a collision, the ECU issues an ignition command, the inflator detonates to release the gas, and the airbag breaks through the cover after restarting to form a bag, so that the occupants like the forward rush will not hit the steering wheel or dashboard or other auto parts.

The power of the airbag is very good protection, which can prevent the owner from accidentally protecting the head from too much injury, and will not hit the steering wheel or dashboard or other car parts.

An airbag is all about keeping your head from hitting an object directly.

The person bounces onto the airbag, and the airbag protects the person from injury.

Airbags can reduce the impact on the driver's face.

The pop-up airbag slows the impact.

It can protect the head and face of members very well.

When the airbag is deployed, it prevents people from touching the car.

The airbag is deployed to prevent people from crashing directly into the car.

In the event of a collision, the occupant of the forward rush does not crash into the steering wheel or instrument panel or other car parts.

The function of the airbag is mainly to prevent injuries caused by collisions between the occupants of the car and the internal parts of the car during a car collision, and it is usually used as an auxiliary safety device for seat belts, and the two work together.

How airbags work.

An airbag is a passive safety system device that is only activated when the vehicle is hit violently. The airbag is determined by the pressure sensor of the airbag system and the acceleration sensor in the ECU of the restraint system.

When the two receive the signal together, the airbag will be inflated instantly, expand sharply, break through the decorative plate of the steering wheel, and bounce to the driver, so that the driver's upper body is wrapped in the airbag, reducing the direct collision force between the human body and the car body.

Airbag precautions:

Be careful not to place objects in front, above, or near the airbag. Since the airbag will detonate in an emergency, do not place objects in front, above or near the airbag to prevent it from being ejected by the airbag during detonation, thereby injuring the occupants. In addition, when installing accessories such as CDs and radios indoors, it is necessary to comply with the manufacturer's regulations, and do not modify the parts and circuits within the scope of the airbag system at will, so as not to affect the normal operation of the airbag.

Children should be especially careful when using airbags. Many airbags are designed for adults, including the position of the airbag in the car, its height, etc. When the airbag is inflated, it can cause injury to the child in the front seat. It is advisable to place the child in the middle of the back row and secure it.

The role of airbags.

In order to reduce the damage to the driver and occupants caused by the huge inertial force in the event of a frontal collision of the car, the current car is generally equipped with airbags in the driver's steering wheel**, and some cars are also equipped with airbags at the upper end of the glove box in front of the passenger seat and the passenger seat.

When a head-on collision accident occurs in the car, when the airbag control system detects that the impact force exceeds the temple value, the airbag electronic control device immediately connects the squib circuit in the inflatable element, ignites the ignition medium in the squib, and the flame ignites the ignition powder and gas generator, produces a large amount of gas, and inflates the airbag within a short time, so that the airbag expands sharply, rushes out of the steering wheel cover, buffers the impact on the driver and occupants, and then releases the gas in the airbag. The junior high school has proved that the degree of injury to the driver and occupants in a frontal collision is greatly reduced when the car is equipped with airbags.

Some cars are equipped with not only front-end airbags, but also side airbags, which can also inflate the side airbags in the event of a side impact to reduce injuries in the event of a side impact. According to statistics, when the airbag collides with a car, the head injury rate is reduced by 25%, and the facial injury rate is reduced by about 80%.

The airbag will eject when the vehicle has a frontal collision, at this time it will avoid the driver and passengers from a secondary collision, which greatly reduces the number of personnel.

Car airbags canIt plays a protective role in the event of danger and reduces the injury to passengers.

The airbag plays a protective role, and in case of danger, the airbag will automatically pop out to protect the person's head, which plays a very important role.

Car airbags can maximize personal safety in the event of an impact and can play a life-saving role.

It can protect our personal safety, airbags play a big role, and every car has such airbags.

The main purpose of airbags is to prevent injuries caused by collisions between the occupants of the car and the interior parts of the car during a car collision.

As soon as the vehicle starts to slow down due to the accident, the airbag is immediately inflated. As soon as the driver's or passenger's head comes into contact with them, they begin to deflate. If the airbag is not designed to deflate, then it will not solve the problem of sudden backward movement of the head and neck because your head will simply pop off.

All of this is possible thanks to a series of sensors and a small **. The airbag includes an accelerometer that detects changes in speed. If it detects that the deceleration is higher than the preset speed, i.e. greater than the normal braking speed, the airbag circuit is triggered.

This circuit causes an electric current to pass through the heating element, which ignites the chemical explosive. This creates a large amount of harmless gas that rushes into the nylon bag. The bag, which fits in the space behind the steering wheel or on the passenger's side dashboard, expands.

When the driver's or passenger's head touches the bag, the bag begins to deflate, and the gas escapes through a small hole in the edge of the bag. By the time the vehicle comes to a complete stop, the bag should have been completely deflated.

Do airbags work? Airbags are a supplemental restraint system, meaning they are designed to work with seat belts rather than being relied upon. It has been found that frontal vehicle crash fatalities can be reduced by up to 24% if airbags are used correctly.

This percentage will only rise as airbag design and general vehicle safety improve.

However, you do need to be careful when using airbags. The violent** that makes the airbag work carries a small risk of eye injury and hearing loss. There are also dangers associated with the use of airbags in vehicles carrying young children.

Although modern airbags inflate less than older models, it is still recommended not to place a child seat facing backwards on the front seat of a vehicle with an active airbag. The number of accidental fatalities due to airbag use has decreased due to changes in airbag design and improved driver education on airbag use.

Knowing more about how airbags work can help you understand why many modern vehicles have them as standard. It can also help you understand why they don't every time you brake or encounter a signal. They are just one example of how modern technology can make driving safer for everyone.

If there is a problem with the airbag, it will not be able to inflate to protect the safety of personnel when the vehicle encounters danger, which will greatly improve the death rate of personnel.

When the car is impacted, it will not be able to successfully deploy the airbag, which will also affect the safety of the people in the car, and the impact is also quite large.

1. The airbag light is lit only to mean that the airbag system of our car has a failure problem, so the failure of our safety system will only affect our car in the event of a collision, our Anchun Hanming full airbag old sales system will not work to ensure our safety;

2. In the case of a problem with the airbag, after we start the car engine, we can see that the fault indicator in the above picture will always be on, so it means that there is a problem with the airbag system of our car;

= The car's airbag protects the passengers through the gas in the airbag, and the basic principle is that when a collision occurs, the gas in the airbag can significantly reduce the force of the impact.

If the car collides to a certain extent, the airbag will produce a chemical reaction similar to a small bomb, and the internal airbag will expand at the moment of hitting the driver, and at the same time as hitting the driver, the airbag will also expel the gas in the air through the air hole, reducing the impact damage to passengers.

In an airbag system, there are two types of sensors: barometric pressure sensors and accelerometers. When a car collides, both devices receive a signal and the airbag is activated.

The gas in the airbag will quickly bulge and then squeeze out of the airbag and fly towards the driver. At this time, the airbag can wrap the upper body of the driver and passengers, so as to reduce the impact of hard objects.

Airbags are often used as an extra layer of protection, and without seat belts, airbags are useless. According to the survey, airbags alone can reduce accident fatalities by 18%, seat belts alone can reduce fatalities by 42%, and combining airbags with seat belts can reduce fatalities by 47%.

Therefore, airbags need to be used in conjunction with seat belts, which can reduce the number of fatalities.

Today, the passive safety of automobiles is becoming more and more important, in some high-end cars, more than 30 airbags are installed, and the coverage of airbags has been very, very wide, from the neck, knees, and even two airbags are installed on both sides of the roof, which can reduce the pressure on the roof in an emergency, and can also play a role in protecting the head and neck.

The knee airbag is a relatively fast developing automobile product in recent years, it is in the driver's seat of the front row, if opened, it can effectively protect the waist and legs of the rear seat, and at the same time can also reduce the impact of the forward rush.

In the event of an accident, it will eject, so that passengers can be prevented from colliding, and the main principle is to protect passengers by air pressure.

When the vehicle collides, the airbag will be deployed to play a protective role, which will prevent people from being injured; Its principle is to continuously send information about the change of speed to the control device through the sensor, and the control device analyzes and judges it.

Generally, from the collision to the human body touching the steering wheel, the airbag controller detects the collision, and at the right time, it will send out an ignition current to detonate the inflator, and the air bag can be filled in 30 50ms, so as to protect the head and neck of the person from injury.

How do airbags work? The airbags on the car are represented as SRS in English, and the full name is Supplemental Inflatable Restraint System, which means Auxiliary Occupant Restraint System. Airbags and seat belts, like safety belts, are "better than nothing" assistive devices in the event of an accident.

The components of an airbag mainly include sensors, microprocessors, electronic control units, airbag covers and support rings, airbags, airbag modules, etc. When a vehicle collides, the sensor senses the intensity of the vehicle's collision and transmits the signal to the controller. After receiving the signal from the sensor, the controller determines whether the airbag needs to be activated.

When it is determined that the airbag needs to be opened, it immediately emits an ignition signal, triggering the inflator. The inflator quickly ignites after receiving the signal, triggering a chemical reaction similar to a small dose of explosive**, causing the airbag hidden in the car to inflate and pop out instantly. It seems like a complicated process, but in fact, the whole process takes no more than a second.

Usually, the chemical reagents used are sodium nitride or ammonium nitrate. Airbags can cushion the impact potential energy of the occupants in the event of an accident, thereby protecting the safety of the occupants. At the same time, the safety airbag is also equipped with a safety valve, which can automatically release part of the gas when it is overinflated or the internal pressure exceeds a fixed value, preventing passengers from being crushed.

Generally, the mainstream family car is equipped with an airbag in front of the main and co-pilot, and protects the head and face of the main and co-pilot in a frontal collision, which is called the main and co-pilot airbags. Two airbags will also be installed on the side of the main and passenger seats of the high-spec model to protect the main and passenger passengers during side impacts. At the same time, existing knee airbags are also installed in front of the main and co-pilot's knees to protect their legs in a frontal collision. Every.

With the development of society and economic progress, every household now has one or two cars. So for these cars, parents are also very loving, and often send them to some car maintenance stations for some maintenance. In this way, the safety of the car is strengthened, and at the same time, the driver of the car is protected.

So we all know that there is a very important part in the car, that is, the airbag of the car, because the airbag of the car can be said to be an indispensable part, so what we are going to talk about today is what kind of role does it play?

Working principleFirst of all, when we understand the role of airbags, we must understand its working principle, because airbags can be said to be a passive safety system device. When the driver is driving the car when there is a violent impact will be activated, then the airbag is mainly through some pressure sensors of the airbag system, as well as the acceleration sensor of the restraint system ECU to determine whether the airbag should be deployed to achieve a protection for the driver.

Protect the chest and head, so when the airbag receives a certain signal, the airbag will be quickly impacted and inflate sharply. In addition, the trim of the steering wheel is broken and bounced at the driver and co-driver, which can reduce the collision ability between the human body and the car body, and reduce the damage caused by the impact. Then when the airbag is deployed, it can protect the head and chest of the driver and co-pilot in time to avoid some fatal injuries.

Don't put too much debris in the car, and finally the car driver must pay attention to safety when driving the car, the normal operation of the airbag, and never stick some broken diamonds or add some decorative items on their steering wheel. In this case, it is very likely that when it receives some violent impact, the airbag will be blocked by some items. If the airbag cannot be properly deployed, it will be fatal for the driver.
