1. What is the impact of airbags on safety
When the car is subjected to a strong frontal impact, the airbag will inflate and expand in an instant to ensure the safety of front seat passengers. Its function is to protect passengers and reduce collisions with objects inside the car, greatly reducing the possibility of injury. And more evenly distribute the collision force on the head and chest, absorb the movement energy of the passengers, thereby supplementing the safety belt.
2. What determines whether airbags can protect safety
It is worth noting that car airbags are known as’ life saving devices’, but as passive safety systems, not all impacts will successfully ‘summon’ car airbags. It only shows off when ‘necessary’, which is why we do not feel the presence of airbags in our daily driving.
In short, a safety airbag is an airbag bag that can ensure the safety of the driver’s life in the event of danger. The safety airbag of a car consists of a sensor for airbag inflation and an inflation system,. Utilizing multiple sets of sensor systems installed at the front of the vehicle, it senses the degree of impact between the vehicle and foreign objects and continuously sends speed change information to the control device. The control device analyzes and judges this information to determine whether it is necessary to ignite the airbag.
3. Hidden dangers of airbags
The airbag cover above the passenger airbag is closely connected to the upper body of the dashboard. During the instantaneous “ejection” of the airbag, fragments flying out of the dashboard at high speed along with the airbag are not only prone to scratching the airbag, causing airbag failure, but also causing harm to the human body, making the airbag unsafe.
4. Application of Laser Weakening in Automotive Airbags
To prevent the generation or flying out of material fragments and ensure that the safety airbag pops up along a fixed trajectory at critical moments, the consistency and accuracy of the fracture strength at all points of the airbag line are crucial, and the machining accuracy of each hole is not guaranteed. With the continuous changes in the weakening process of automotive instrument panel airbags, laser weakening
technology and laser weakening system
for automotive instrument panel airbags have emerged.
Since the third generation, HGTECH’s laser weakening automation equipment
has been equipped with a self-developed real-time full closed-loop control system, while the fifth generation has optimized the data recording and storage function. Dozens of sensors “hidden” in the equipment collect data on laser energy, drilling density, residual thickness, and other factors during the processing through their “antennae”, which are then fed back and stored in the control system. The production data of each product can be traced for 15 years, which is also the biggest advantage of laser weakening technology compared to traditional processing methods such as cold cutting, hot cutting, and milling.
