Description

Protective air bag, wearable protective equipment and safety protective equipment

Technical Field

The utility model relates to a collision protection technical field, concretely relates to protective airbag, wearable protective apparatus and safety protection equipment.

Background

Airbags are one of the most prominent automatic protection technologies in use today. The safety protection device is widely applied to the field of automobile safety protection and other safety protection fields. The existing safety air bag has an action mechanism that high-pressure gas is quickly generated in a short time by a high-pressure gas bottle or a chemical reactor to inflate the air bag. Then the inflated air bag forms a buffer area between the human body and the impact object, thereby achieving the purpose of protection.

One of the basic characteristics that limit the range of use of an airbag, however, is that the airbag is disposable. Due to the one-off working principle of the traditional safety air bag, on one hand, the use cost of air bag protection is overhigh; on the other hand, the safety of the airbag is also affected to some extent. The setting of the airbag opening threshold is relatively high because it is disposable and expensive. In many low-speed traffic accidents, the air bag cannot be ejected. The same problem exists in applying conventional airbag technology to the protection of a human body from falls.

At present, in the field of human body protection (impact, fall and the like), the prior technologies and methods in the world have no more than two types. One is based on inert physical structures (as distinguished from active responses, pops or changes to emergencies) such as pads, helmets, lined soft bodies, etc. The intelligent judgment capability is not contained, and the problems of folding and releasing do not exist. The other type is based on the protection mode that the air bag is rapidly inflated in an emergency to form an air cushion. The falling protection is carried out on the fragile body of the old, and the article worn by the old is almost impossible to be portable, small and complete in protection. In addition, the use of air bags for fall protection has significant technical drawbacks, and is fatal and difficult to overcome. The most important drawback of airbag technology when applied to fall protection is that its deployment is disposable. However, for one-time use, fall protection is a fundamental contradiction, as one wave train occurs, determining whether the next break or no break involves a large number of uncertainties such as whether the ground is slippery at the time, the physical condition of the elderly, mental condition, etc. At this time, if the airbag is selected not to be opened, a real fall can be missed, and the airbag is selected to be opened, so that the probability is high, the airbag is not fallen, but the airbag is abandoned. These must be judged at the instant the fall occurred without being completed. This is an insurmountable dilemma for disposable airbag protection technologies.
