Embodiment 1

[0028] Such as Figure 1-3 As shown, a watch movement electronic setting needle timing mechanism, which includes a circuit board 301, a positive plate 471 connected between the circuit board 301 and the power supply, and a stepping motor for driving the electronic setting needle to rotate, on the circuit board An integrated control circuit for controlling the work of the stepper motor through output pulses is connected; the timing mechanism also includes a stop second column 307 made of conductive material, a stop second lever 456, an arbor 401 and a switch puller 474;

[0029] The second stop post 307 is fixedly installed in the casing of the watch movement and electrically connected with the circuit board 301;

[0030] The second-stop lever 456 is located beside the second-stop column 307, one end of the second-stop lever 456 is rotatably connected to the housing of the watch movement, and the other end is electrically conductive and rotatably connected to the inner end of t...

Embodiment 2

[0035] When the stem 401 moves outwards until its non-circular shaft section is located in the non-circular hole 4741 of the switch dial 474, the stop second lever 456 can contact the stop second post 307, so that the circuit board 301, stop second post 307 , the second stop lever 456, the stem 401, the positive plate 471 and the power supply are sequentially connected to form a second stop trigger circuit, and the integrated control circuit is connected to the second stop trigger circuit. When it is detected that the second stop trigger circuit is turned on , stop outputting pulse commands to the stepper motor.

Embodiment 3

[0037] When the arbor 401 moves outward until its non-circular shaft section is located in the non-circular hole 4741 of the switch paddle 474, the arbor 401 is also in conductive contact with the switch paddle 474, and when the arbor 401 is rotated, the One of the contacts 4743 of the switch paddle 474 is connected to the copper film contact 310 on the corresponding side, so that the circuit board 301, the copper film contact 310, the switch paddle 474, the stem 401, the positive pole piece 471 and the power supply are connected in sequence. The formed timing trigger loop is turned on, and the integrated control circuit is connected to the timing trigger loop. When it is detected that the timing trigger loop is turned on and reaches the set time, it outputs to the stepping motor to make the stepping motor move forward and reverse quickly. Turning timing pulse instruction.

[0038] For example, when the stem 401 is manually turned forward or backward, if the contact 4743 on th...

Abstract

The invention relates to an electronic setting hand timing mechanism of a movement of a wrist watch. The electronic setting hand timing mechanism comprises a circuit board, a positive electrode plate and a stepping motor, wherein the positive electrode plate is connected between the circuit board and the power supply; the stepping motor is used for driving the electrode setting hand to rotate; the circuit board is connected with an integrated control circuit for controlling the stepping motor to operate by outputting pulse. The electronic setting hand timing mechanism is characterized by also comprising a second stop column made of a conductive material, a second stop rod, a handle shaft and a switch shifting sheet. The electronic setting hand timing mechanism has the beneficial effects that the mechanism can reduce parts of a quartz wrist watch, moreover is simple to operate, has no gear damage or hand shaking and vibration, does not need too much high processing precision and the like, and also can enhance the quality of the movement and the use reliability.

Description

technical field [0001] The invention relates to a quartz watch movement, in particular to an electronic dial timing mechanism without a clutch-over wheel structure. 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. Contents of the invention [0004] The invention provides an electronic needle timing mechanism for a watch movement. It is an electronic needle timing mechanism without a clutch-over wheel structure. Needle, n...
