Automobile collision sensor united with sensor for sensing the amount of collision

摘要

PURPOSE: A collision sensor for vehicle including an impulse sensor is provided to detect the impulse according to a variation of magnetic field by forming a collision sensor and an impulse sensor with one body. CONSTITUTION: A collision sensor for vehicle including an impulse sensor includes the first and the second housings(3,5), a collision sensor(30), an impulse sensor(40), and a terminal(7). The first and the second housings(3,5) are formed with one body. The collision sensor(30) includes a mover(31) installed within the first housing(3), a magnetic body(32) installed at a side of the mover(31), a coil spring(33) for supporting the mover(31), and a switch portion(34) installed within the first housing(3). The impulse sensor(40) includes an electric motor(41), a tone wheel(43), and a magnetic variation detection portion(44). The terminal(7) is installed at the first and the second housings(3,5).
