Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
The utility model provides a protective air bag device's technical principle as follows:
the airbag device includes: the airbag box is arranged at the bottom of the A column of the automobile according to a preset distance; the airbag box is cut from the inner front end of the front door inner decoration plate of the vehicle; an airbag disposed within the airbag case; a weakening cover disposed on a top surface of the airbag case; the air bag in the air bag box breaks the weakening cover after being inflated and unfolded.
Example one
The present embodiment provides an airbag device including:
the airbag box is arranged at the bottom of the A column of the automobile according to a preset distance; the airbag box is cut from the inner front end of the front door inner decoration plate of the vehicle;
an airbag disposed within the airbag case;
a weakening cover disposed on a top surface of the airbag case; the air bag in the air bag box breaks the weakening cover after being inflated and unfolded.
The airbag protection device provided in the present embodiment will be described in detail with reference to the drawings. Please refer to fig. 1, which is a schematic perspective view of an airbag device according to an embodiment of the present invention. As shown in fig. 1, the air-bag unit 1 includes: air bag, 14, air bag 13 and weakening cover.
In this embodiment, the airbag case is a trim panel 14 of a front door of a vehicle, the airbag case may be used as a separate airbag housing device and may be fixedly connected to other parts of the vehicle to prevent a risk of collision between a passenger and other parts of the vehicle, the weakening cover is disposed directly below the airbag 13, and at this time, the airbag 13 is in a deployed state, and the airbag protection device further includes: the air bag 13 is fixedly connected with an air bag explosion unit.
In practical application, the airbag 13 is inflated and deployed in an L shape in a working state. The expansion shape of the air bag 13 also includes a sphere, a square, a T shape, a column and the like, and the air bag 13 is filled in the corner with potential safety hazard of the automobile in the shape to ensure the driving and riding safety of passengers.
The airbag 13 is located between the driver airbag 12 and the side curtain 11 of the automobile after inflation and deployment. If the passenger does not deflect, the driver airbag 12 of the automobile can protect the safety of the passenger; if the passenger deflects laterally and forwards, the air bag 13 can protect the safety of the passenger; if the passenger has large transverse rotation, the side air curtain 11 can protect the safety of the passenger.
