A clutchless wheel electronic setting needle timing pointer type quartz watch movement

Abstract

The invention relates to a clutching-wheel-free electronic hand setting and time-correction pointer type quartz watch movement. The clutching-wheel-free electronic hand setting and time-correction pointer type quartz watch movement comprises a shell of the watch movement, wherein the shell of the watch movement is provided with an electronic hand setting and assembly, a stepping motor, a circuit board, a driving wheel system which is connected between the electronic hand setting and assembly and the stepping motor and is used for driving the electronic hand setting and assembly to work, and a positive electrode piece connected between the circuit board and a power supply; the circuit board is connected with an integrated control circuit for controlling the stepping motor to work through output pulse. The clutching-wheel-free electronic hand setting and time-correction pointer type quartz watch movement is characterized in that the shell of the watch movement is further internally provided with a second stopping column made of a conductive material, a second stopping rod, a handle shaft and a switching pulling piece. The watch movement provided by the invention is provided with a clutching-wheel-free electronic hand setting and time-correction mechanism, and has the advantages of few parts, simplicity in installation, no damages on gears, no hand shaking, no hand swaying, no need of too high machining precision and the like; and the quality of the movement and the use reliability can be improved. Clockwise hand manipulation and anticlockwise hand manipulation can be carried out through display hour, minute and second hands according to function requirements.

Description

technical field [0001] The invention relates to a quartz watch movement, in particular to a clutch-wheel-free electronic setting needle timing pointer type quartz watch movement. Background technique [0002] Quartz electronic watches have the advantages of accurate timekeeping, beautiful appearance, and the need for operations such as mechanical watch tightening, and are loved by people. However, the mass-produced analog quartz watch movements of various companies on the market currently use a clutch wheel structure for time adjustment. Calibration function. [0003] This kind of movement that adopts the clutch and passing wheel mechanism to adjust the time has complex parts, unreliable work, easy tooth damage, slow watch stop, high failure rate and high processing difficulty. [0004] Moreover, the existing quartz watch movement can only rotate the row needle clockwise, and the watch movement includes a control circuit, a stepping motor, and a transmission wheel train com...

AI Technical Summary

Problems solved by technology

The existing quartz watch movement cannot realize clockwise and counterclockwise movement, that is, the hour, minute and second hands cannot realize clockwise and counterclockwise movement according to functional requirements
