Problems solved by technology

[0002] At present, the time adjustment of quartz alarm clock movements on the market is mainly controlled by manual dials, so that the hour and minute hands rotate clockwise synchronously. Since a stepping motor is used in the structural setting, the power supply provides power to the stepping motor. , there are many transmission mechanisms, it cannot rotate counterclockwise at the noisy point, the time adjustment is relatively slow, not convenient enough, and it does not have a stopwatch function at any time, and it cannot realize the quick reset of the two hands, the start and stop of the stopwatch, and the automatic quick recovery The current standard time, also cannot perform the countdown function

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] As shown in accompanying drawing 1, stepper motor of the present invention is made up of rotor, stator plate and drive coil, is provided with two rotors on stator plate, minute hand rotor 3 and hour hand rotor 2, and two rotors are installed in a common stator On sheet 4, the hour hand rotor and the minute hand rotor cooperate with the stator sheet respectively to form an hour hand stepping motor and a minute hand stepping motor. On the chip, the hour hand driving coil is divided into forward rotating hour hand driving coil 5 and reverse rotating hour hand driving coil 6, and the minute hand driving coil is arranged on the stator sheet, and the minute hand driving coil is divided into forward rotating minute hand driving coil 7 and reverse rotating minute hand driving coil 8. And it is connected with the printed circuit board, and the printed circuit board is provide...

Abstract

The invention relates to an automatic quartz crystal clock stepper motor, belonging to the timing device area, particularly in relation to the stepper motor used on a quartz crystal clock, and it comprises the rotor, the stator slice and the driven coil, and on the stator slice equipped two or more rotors, on the stator slice equipped the driven coil, and two or more rotors installed in a shared stator slice, and each rotor has the driven coil, and the rotors respectively matching the stator slice, and the driving coil is installed and fixed on the stator slice through the standing. The invention has novel structure, cleverly conceived, and the stepper motor directly and separately controls hour hand and minute hand, the machine core with simple structure and with only two stepper motors, no other drive machine in the machine core, it can achieve normal walking and rapid execution of the various functions.
