AI Technical Summary

Technical Problem

Existing magneto motors cannot be deactivated under short-term high acceleration conditions but can be activated under long-term low acceleration conditions, thus failing to meet diverse triggering requirements.

Method used

A magneto structure was designed, including a guide cylinder, a magnetic core, a spring, a shear plate, and a coil. An induced voltage is generated in the coil by the cutting of the shear pin and the movement of the magnetic core. The movement of the magnetic core is controlled by the electromagnetic resistance of the spring and the armature, ensuring triggering under long-term low acceleration.

Benefits of technology

It achieves reliable triggering under long-term low acceleration, provides a stable electrical signal, has an economical and safe structure, and is suitable for the ignition requirements of fuses.

Abstract

The application discloses a magneto, which comprises a shell, a magnetic core, a spring, a shear plate, a shear pin and a coil; the magnetic core is arranged in the shell; the spring is arranged between the magnetic core and the shell, and the lower end of the spring is abutted against the inner side surface of the shell; the shear plate and the guide cylinder are sleeved on the outer side surface of the magnetic core, and the upper end of the spring is abutted against the bottom of the shear plate; the shear pin is arranged on the shear plate and is inserted into the magnetic core; the magnetic core is cut off from the shear pin when moving downwards in the shear plate; the bottom of the shell is provided with the coil; the magnetic core enters the coil after being cut off from the shear pin, so that the coil generates an induced voltage. The magneto of the application can cut off the shear pin under the condition of low acceleration and long duration, and the magnetic core can pass through the coil under the guidance of the guide cylinder to generate an induced voltage, so that the purpose of triggering the magneto is achieved; the structure of the magneto is safe and reliable; the magneto is low in cost and can be triggered under specific conditions.
