Air bag installed inside vehicle door

Abstract

The invention discloses an air bag installed in a vehicle door. The air bag mainly comprises a safety air bag controller, a whole vehicle data communication bus, the vehicle door, an air bag assemblyand the like. The safety air bag controller and the air bag assembly are connected with the whole vehicle data communication bus respectively. The air bag assembly is installed in a cavity between a vehicle door inner plate sheet metal part and a vehicle door outer plate sheet metal part. The air bag assembly comprises a collision sensor, a gas generator and an air bag body, the collision sensor is connected with the whole vehicle data communication bus, the gas generator is fixed in a cavity between a vehicle door inner plate and a vehicle door outer plate, and the air bag body is connected with the gas generator through an inflation pipe. The problem that a vehicle door invades inwards due to side collision is fundamentally solved; the air bag is arranged in the gap between the sheet metal parts of the inner and outer plates of the vehicle door, so that a large amount of development tests and cost can be saved, the response speed of the air bag is greatly increased, the side collision passenger protection effect is improved, and maintenance after accidents is facilitated.

Description

technical field [0001] The invention relates to an automobile airbag, in particular to an airbag installed inside a car door, and belongs to the technical field of vehicle safety systems. Background technique [0002] According to statistics on traffic accidents, injuries and fatalities caused by side collisions rank among the top among all types of collisions. Improving the protection effect of side collisions can greatly reduce the death and injury rate of traffic accidents. Existing technical scheme mainly is equipment side air bag and air curtain, and side air bag is mainly installed in the seat. [0003] The existing technical solution is that the air bag installed in the seat contacts with the human body and buffers the collision energy during the collision process. Therefore, in the current development process, a large number of airbag burst tests need to be carried out to verify that the airbag will not cause side effects when it comes into contact with the human bo...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned problems existing in the prior art, the present invention provides an airbag installed inside the car door, which fundamentally solves the intrusion problem of the car door caused by the side collision, and installs the airbag in the gap between the inner and outer panels of the car door. , because there will be no contact with the human body, it can save a lot of development tests and costs, and at the same time, the airbag response speed is also greatly improved, thereby improving the occupant protection effect in side collisions, and is also conducive to post-accident maintenance
