Eight-directional induction starting device for collision sensor

Abstract

The invention relates to an eight-directional induction starting device for a collision sensor, which comprises an inner magnetic ring and an outer magnetic ring, wherein both the cross sections of the outer side of the inner magnetic ring and the inner side of the outer magnetic ring are octagonal, the inner magnetic ring is movably arranged in the outer magnetic ring and spaced with the outer magnetic ring, the magnetic forces between the inner magnetic ring and the outer magnetic ring are mutually balanced, both the inner magnetic ring and the outer magnetic ring are conductors and are respectively connected with the anode and the cathode of the collision sensor through leads, and under the action of acceleration, the inner magnetic ring moves by overcoming the magnetic forces and is contacted with the outer magnetic ring to conduct the anode and the cathode of the collision sensor. Since the eight-directional induction starting device for the collision sensor with the structure is adopted, because the inner magnetic ring and the outer magnetic ring are not contacted under normal conditions, when a sufficiently large acceleration in a certain direction is obtained, the inner magnetic ring moves by overcoming the magnetic forces, the anode and the cathode of the collision sensor are conducted, and a collision signal is sent out, so that the device has the advantages of capability of inducing the collision in any directions, recycling, simple structure, high reliability and wider application range.

Description

Technical field [0001] The invention relates to the field of sensors, in particular to the field of collision sensors, and in particular to an eight-direction induction starting device for collision sensors. Background technique [0002] Collision sensors are often used in automobiles and other related industries to trigger the activation of safety protection devices such as airbags during a crash, or to cut off the power supply of high-power components. The structure of the currently widely used collision sensor trigger device is directional, generally one-dimensional and two-directional. To use such one-way collision sensors in the forward and lateral directions of the car, a car needs at least four triggering devices, and usually cannot be reused. As a result, the manufacturing cost of the collision sensor is relatively high. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art, and provide a c...
