Device for firing safety air-bag

Abstract

The invention relates to a device used for exploding a safety air cell. The device comprises an input interface, a switch and an output interface; the input interface is used for being connected with a power to connect the power into the device; the switch is used for starting the device; the output interface is used for being connected with the ignition tube of the safety air cell to output the current for exploding the safety air cell. The device of the invention is characterized in that the device also comprises a current lasting time adjusting module and a current strength adjusting module; the current lasting time adjusting module and the current strength adjusting module are connected between the switch and the output interface; the current lasting time adjusting module is used for setting the lasting time of the current for exploding the safety air cell; the current strength adjusting module is used for setting the strength of the current for exploding the safety air cell. The device provided by the invention can be adopted to achieve the goal of accurately exploding the safety air cell and can realize the goal of validating the detonating parameters of the safety air cell.

Description

technical field [0001] The present invention relates to the field of automobiles, and more particularly, to a device for detonating an airbag. Background technique [0002] At present, airbags are generally introduced in motor vehicles. On the one hand, when the vehicle collides, the airbag can reduce the probability of personal injury. cause an accidental explosion, possibly causing accidental injury to personnel. Therefore, the airbag must be manually detonated before the vehicle is scrapped. In addition, there is also a need to manually detonate the airbag to verify the detonation parameters in the airbag test. [0003] In the prior art, whether it is to detonate the airbag inside or outside the vehicle, it is adopted to first short-circuit the line connected with the ignition tube of the airbag, and then connect the two wiring joints of the detonating assembly of the airbag respectively. Connect a long wire (not less than 6 meters) to the socket, and then connect the o...

AI Technical Summary

Problems solved by technology

When using this device and method, the parameter value of the current used for detonation cannot be preset before the detonation, that is, it is impossible to know whether the current given by the battery can detonate the airbag, so it is not controllable

Moreover, after the detonation is implemented, the parameter value of the current for detonation cannot be known by any means such as measurement or calculation, that is, it is impossible to know whether the current given by the battery is suitable for detonating the airbag, so it is not observable.

Furthermore, due to the large volume and high quality of the battery, it is not easy to carry, which will cause inconvenience to the operation.
