Embodiment

[0020] A kind of delayed detonation automobile safety airbag, comprises airbag body, collision sensor, speed sensor, steering angle sensor, pressure sensor, controller and time delayer;

[0021] The airbag body includes an upper airbag at the top, a side airbag at both sides and a lower airbag at the bottom, a total of 4 sub-airbags connected in parallel, and gas generators are respectively arranged in the sub-airbags; when the upper airbag is detonated, it corresponds to the human head, It mainly protects the head of the human body. When the side airbag is detonated, it corresponds to the two sides of the face respectively. It mainly protects the two sides of the face. The airbag should be as large as possible to fully cover the entire torso and protect the internal organs of the chest cavity to the greatest extent. The head airbag is slightly smaller than the other three sub-airbags, aiming to minimize the impact on the head while protecting the head. In this embodiment, the...

Abstract

The invention discloses a delayed detonation automobile safety airbag, which is composed of an airbag body, a collision sensor, a speed sensor, a steering angle sensor, a pressure sensor, a controller and a time delay device. The airbag body includes four parallel sub-airbags; The pressure sensor is arranged on the driver's seat cushion; the steering angle sensor is arranged on the steering column of the steering wheel, and the output ends of each sensor are connected with the controller; and connected with the gas generator in the airbag body through a time delay device; the present invention The sub-airbags can be detonated separately according to the specific collision situation, which can protect the key parts of the human body in a targeted manner, play an effective protective role, and reduce the secondary damage caused by the airbag to the human body as much as possible; and the detonation is accurate High resistance, can better play an effective protective role.

Description

technical field [0001] The invention relates to a delayed detonation automobile safety air bag and a control method thereof. Background technique [0002] With the successive implementation of more and more automobile safety regulations and the increasing requirements of users on automobile safety, the design of automobile safety system is becoming more and more important. In the event of a frontal collision of the vehicle, the airbag installed inside the steering wheel and the instrument panel bounces off when necessary, forming an air wall between the occupant and the vehicle body, thereby reducing the probability of injury; The spherical shape is inflated rapidly, and the impact force when the airbag expands will cause secondary damage to the driver and passengers, and serious casualties will be caused. Contents of the invention [0003] In order to solve the defect in the prior art that the airbag may cause secondary injury to the driver and passengers when the airbag...
