How useful are airbags?

Airbag is a protective measure to protect the driver's head from fatal injury in the event of a collision, it can be in the moment of collision, the airbag pops open, and plays a safety measure to block the driver's head from violent impact, reducing the mortality caused by the collision of the vehicle!

There are often some very unsafe car accessories on a certain treasure, such as a steering wheel mobile phone holder. In the event of a collision, the airbag will explode, and the secondary damage caused by the mobile phone holder will be serious! Yu Yang bought a second-hand airbag and did a test to see how powerful the airbag was.

PS: The trial is risky, and participation should be cautious.

The function of airbags is mainly to prevent injuries caused by collisions between occupants and interior components in the car during a car collision, and usually appear as an auxiliary safety device for seat belts, and the two work together. An airbag system is a passive safety (see Automotive Safety Performance) protection system that, in conjunction with seat belts, can provide effective collision protection for occupants. In the event of a car collision, airbags can reduce the rate of head injuries by 25 percent and the rate of facial injuries by about 80 percent.

The protection principle of the airbag is: when the car suffers a certain collision force, the airbag system will trigger a chemical reaction similar to a trace amount of explosives, the airbag hidden in the car is inflated and popped out in an instant, and the body of the occupant can be in place in time before the collision with the parts in the car, when the human body comes into contact with the airbag, the airbag begins to exhaust through the air hole on the surface of the airbag, which plays a role in paving, reduces the impact force on the body, and finally achieves the effect of reducing the injury of the occupants.

As an auxiliary configuration for the passive safety of the body, airbags have been increasingly valued. When the car collides, the occupant and the vehicle internals have not yet "before the second collision" quickly open an air cushion filled with gas between the two, so that the occupant moves due to inertia and "pounces on the air cushion", so as to alleviate the impact of the occupant and absorb the collision energy, and reduce the degree of injury of the occupant.

The main function of the car airbag is that in the process of driving, if it encounters a dangerous and violent impact, it will automatically pop out to protect the safety of the human body, so it is very important.

The driving and daily maintenance of the vehicle is very important, which directly involves the safety of driving, so it is necessary to communicate with professional and technical personnel to learn and master the daily maintenance of the car.

If you want to communicate and learn more from technicians, you need to master the following points:

1. Smiling and mild-mannered.

Everyone likes to talk to someone who is smiling and soft-spoken, because they can hear a sense of intimacy in that person's speech. Do you feel comfortable when the person you're chatting with is smiling all the time? When his tone of voice makes you comfortable, do you feel the urge to continue talking to him?

2. Be polite in speech and behavior.

When talking to people, be sure to be mindful of what you say and do. If you want to talk effectively with others, you must learn to get along with others politely and make others have a good impression of you!

3. Don't leave the same topic for too long.

Even if it's a topic that both people like, don't keep exchanging opinions on this topic, as it will bore the other person after a long time.

4. Don't talk about other people's sad things.

If you know that the other person has something bad recently, be sure not to mention it during the conversation, otherwise it will cause the other person to be disgusted and uncomfortable.

5. Find common ground.

The ancients said that if you don't speculate more than half a sentence, it means that in order to communicate effectively with people, you must find speculative people, that is, people who have a common topic. Therefore, the focus of effective communication with others is on common topics.

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.

Airbag sensors are also known as crash sensors, and according to different uses, collision sensors are divided into trigger collision sensors and protective collision sensors. The trigger collision sensor, also known as the collision intensity sensor, is used to detect the acceleration change during the collision and transmit the collision signal to the airbag computer as the trigger signal of the airbag computer; The protective crash sensor, also known as the safety crash sensor, is connected in series with the trigger collision sensor to prevent the airbag from detonation.

According to the different structures, collision sensors can also be divided into electromechanical collision sensors, electronic collision sensors and mechanical collision sensors. The protective collision sensor generally adopts an electronic structure, and the trigger collision sensor generally adopts an electromechanical combination structure or a mechanical structure. The electromechanical combined collision sensor uses mechanical movement (rolling or turning) to control the action of electrical contacts, and then controls the opening and cutting of the airbag circuit by the contact opening and closing.

Electronic collision sensors do not have electrical contacts, and are commonly used in two types: resistive strain type and piezoelectric effect type. Mechanical collision sensors are commonly used in mercury switch type, which uses the conductive characteristics of mercury to control the on-on and cut-off of airbag circuits.

Front airbag: Driver front airbag, the driver's front airbag is installed on the steering wheel**, in order to avoid unnecessary detonation of the airbag, so do not hit the steering wheel ** position. Passenger airbags:

Passenger front airbag, the front passenger front airbag is installed in the square dashboard, do not place items in this position to avoid danger. Side airbag: side tubular or side curtain airbag, the side airbag is generally installed on the outside of the seat, or will be installed on the upper frame of the side door, and some models will be installed on the A-pillar.

Knee Airbag: The knee airbag is mounted under the dashboard.

When the car is hit, the airbag will automatically deploy, immobilizing the driver's body and preventing the driver from being injured.

What do you say, what do airbags do? Of course, it is as simple as putting this airbag in the first place to prevent people from ejecting after overturning. In a word, it is to save your life.

Airbags for cars. It is used when there is a car accident, that is, when the car is violently collided, it ejects. Protects to the human body.

The function of airbags is to reduce the degree of injury to the occupants in the event of a collision and to prevent the occupants from being thrown out of their seats in dangerous situations such as secondary collisions or vehicle rollovers. In the event of a collision, the inflation system inflates quickly in less than a tenth of a second, and the airbag will rush out of the steering wheel or instrument panel as it inflates. This protects the occupants from the forces of a positive collision, and after about a second, the airbag retracts (there are many small holes in the airbag) so that it does not impede the movement of the occupant.

Prevent the passenger from colliding with the parts in the car, causing secondary damage, and play a role in cushioning the impact force. When a car collides, if the collision is severe. When a certain threshold is reached, the requirements for airbag operation will be met.

At this time, the inflator inside the airbag will release a large amount of non-toxic gas, which will then expand. Pop out the cover on top and start protecting the critical parts of the occupants of the car, preventing the driver from coming into direct contact with the car.

Even if airbags can protect the safety of people in the car to a certain extent, they may not protect you well. Airbags only protect your safety as much as possible, but it is the owners themselves who can really protect the safety of the car owners. He must obey the traffic rules and drive well.

A: It can reduce the degree of injury to the occupants of the car. It is a passive safety protection system.

Used in conjunction with seat belts, it can provide effective collision protection for passengers. When a car crashes, the rate of head injuries can be reduced by 25% and the rate of facial injuries can be reduced by 80%.
