Oscillation structure controlled by electrical energy conversion for balance spring oscillating system

Abstract

The invention discloses an oscillation structure controlled by electrical energy conversion for a balance spring oscillating system. The oscillation structure comprises a movement main clamping plate and a balance spring oscillating system arranged on the movement main clamping plate, wherein the movement main clamping plate is further provided with a stepping motor driving system; and the stepping motor driving system is used for driving oscillation of the balance spring oscillating system. According to the oscillation structure, the balance spring oscillating system of an automatic watch and an oscillating circuit of a quartz watch can be perfectly combined, and the characteristics of accurate timing, low cost and easy processing can be achieved.

Description

technical field [0001] The invention relates to a movement part of a watch, and more specifically, relates to an oscillation structure for controlling the oscillation system of the balance spring by electric energy conversion. Background technique [0002] Existing watch movements are roughly divided into three types according to power sources: mechanical watch movements, quartz watch movements and kinetic energy watch movements. [0003] Mechanical watch movement has a very long history. Its travel time power comes from the human body, which stores mechanical energy through the movement of the human body. One is manually wound, and the other is to use an automatic pendulum to accumulate energy through arm swing. Mechanical clocks and watches use springs as the driving force, through a transmission system composed of a set of gears to drive the escapement governor and balance spring oscillation system to work, and then the escapement governor and balance spring oscillation s...

Problems solved by technology

However, how to combine the oscillation system of the balance wheel and hairspring of the automatic mechanical watch with the oscillation circuit of the quartz watch to form a new product module, the main technical difficulty is that both have their own signal sources, and the oscillation system of the balance wheel and hairspring is a mechanical signal. Fixed vibration period, the movement form is reciprocating rotation, while the quartz watch first converts the electrical signal into a magnetic signal and then converts it into a mechanical signal output, and the movement form is a single direction rotation
