Problems solved by technology

At present, the collision sensors used in automobile airbags mainly adopt mechanical or piezoelectric acceleration sensors, which are all set to collide directly in front, and the collision angle is small. Collision cannot be artificially specified in its direction, so there is a technical safety gap

Abstract

An angualr collision sensor for safety air bag of automobile includes fixing screw in the center of cover top, support with trimming screw, petal dish shape elastic element contacting in sequence with the trimming screw, suspended ball and suspended pendulum with electric brush, ring contactor outside the electric brush with connecting wires extending beyond the cover, insulating seat and base board. The sensor makes the safety air bag capable of responding to any angular collision over the set speed to output start signal without lag.

Description

technical field [0001] The invention relates to a sensor, in particular to an automobile angular collision sensor, which is suitable for safety airbags of various automobiles. Background technique [0002] Automobile airbag is a device that provides safety protection for occupants in automobile collision accidents. It does not need human control but is controlled by collision sensors, so collision sensors are its key components. At present, the collision sensors used in automobile airbags mainly adopt mechanical or piezoelectric acceleration sensors, which are all set to collide directly in front, and the collision angle is small. The directionality of a collision cannot be artificially specified, so there is a technical safety gap. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technologies, and provide a vehicle that can respond synchronously and effectively when any angular collision occurs ab...
