Backpack-type protective airbag device

Abstract

The invention provides a backpack-type protective airbag device; acceleration changes of the body in all directions are detected based on a tri-axial gyro acceleration transducer, a body state of impeding falling down is calculated by a microcontroller control system; meanwhile, whether the body reaches a state of falling into water is detected by a pressure transducer, and, when the system determines that the body reaches the state of impeding falling down or falling into water, airbags arranged inside a backpack and a backpack strap are opened to protect critical organs of the body; and the body is effectively protected against the accidents of falling, impact, drowning and the like. The airbag device can be reused, has beautiful appearance and is easy to carry and simple to use.

Description

technical field [0001] The invention relates to the technical field of safety airbags, in particular to a portable human body protection airbag. Background technique [0002] In the process of daily life, exercise and work, people often face many high-risk environments, such as driving motorcycles, extreme sports, water sports, etc. Various subjective and objective risk factors are always threatening people's life safety. Due to objective reasons, people cannot completely avoid these dangers, so many people in the world are injured or even killed every day because of car accidents, falls, and drowning. Therefore, it is necessary to adopt better methods to change these status quo, so that people can reduce or completely avoid physical injury or even save their lives in case of accidents such as bumping, falling, and drowning. [0003] In response to this problem, there are also air bag devices for pedestrian protection in the prior art, such as products such as the old man'...

AI Technical Summary

Problems solved by technology

The principle of this kind of product is to use the sensor to detect the inclination angle of the human body to trigger the airbag inflation protection. However, because of the principle of the angle sensor, it is easy to be falsely triggered when the human body accelerates or bends down, so it is easy to cause false activation of the airbag device in actual use. Happening

At the same time, the existing technology only protects a certain part of the human body, and lacks the protection of all important organs of the human body.

In addition, the prior art products also have the disadvantage of single function, lack of protection functions such as drowning, and the product itself has disadvantages such as overweight, inconvenient wearing, and lack of aesthetics.
