Electromechanical transform structure of mechanical temperature controller

Abstract

The invention discloses an electromechanical transform structure of a mechanical temperature controller. The electromechanical transform structure comprises a watch movement lower gear, a propulsion rack, a lateral propulsion rack guiding structure, a magnetic core strip, a spring, an inductor coil and a signal conversion circuit. The watch movement lower gear is linked to a watch hand of a mechanical temperature controller; the propulsion rack is engaged with the watch movement lower gear; the magnetic core strip is fixed at one end of the propulsion rack and can extend into or exit from thefixedly set inductor coil; the spring is fixedly connected to the other end of the propulsion rack; and the signal conversion circuit connected to the inductor coil is used for collecting the inductance of the inductor coil, acquiring position information of the watch hand based on the inductance, and then converting the position information of the watch hand into an electrical signal for outputting. Therefore, the electrical signal of the mechanical watch is outputted; the safety and reliability are high; the anti-vibration effect is good; and the electromechanical transform structure has advantages of miniaturization, low cost, long service life, small temperature drift and wide temperature application range.
