Intelligent automobile auxiliary safety device

Abstract

The invention discloses an intelligent automobile auxiliary safety device comprising a safety belt. A compression cavity is disposed in the safety belt body; an air sac is foldably arranged in the compression cavity; a slit is formed in one side of the safety belt body close to a chair; the end part of the air sac is provided with an air inlet; an arc-shaped recessed part is arranged on the side wall facing to the slit of the middle of the air sac; the inner wall of the middle of the recessed part is provided with a tightening port; two different points are selected from the inner wall of the middle of the recessed part; starting from the points, the inner wall of the air sac is folded and sewed to form a plurality of independent wrinkles; the plurality of wrinkles are annularly distributed and form an airflow channel, a tightening port; the main contact parts between the safety belt main body and the upper trunk are areas from the shoulders to the chest part and to the belly side; and the arc-shaped recessed part in the middle of the air sac is adaptive to the contact parts, so injection damage to the contact parts by the middle of the air sac after collision can be prevented.

Description

technical field [0001] The invention relates to an intelligent automobile active safety system, in particular to an intelligent automobile auxiliary safety device. Background technique [0002] In the study of automobile safety, the airbag, as an auxiliary configuration of the passive safety of the body, has been paid more and more attention by people. When the car collides with an obstacle, it is called a primary collision, and when the occupant collides with the internal components of the vehicle, it is called a secondary collision. When moving, it "flutters on the air cushion" to ease the impact on the occupant and absorb the collision energy, reducing the degree of injury of the occupant. Airbags are widely used in automobile interiors, including driver airbags, passenger airbags, front side airbags, curtain airbags, and knee airbags. An airbag is generally composed of a sensor, an electronic control unit, a gas generator, an airbag, a freewheel, etc. Usually, the gas ...

AI Technical Summary

Problems solved by technology

[0003] But the safety airbag in the prior art has the following defects. The safety airbag system belongs to a passive safety system and cannot implement active safety protection for passengers; The airbag system will not activate at all times, and due to the sharp changes in driving conditions, the driver will not be seriously injured even under the protection of the seat belt, but it is precisely because of the restriction of the seat belt on the driver's upper Person's upper torso sustained significant strangulation
