As shown in FIG. 1 , a clock structure of a locking clock includes a drive mechanism 1, a linkage assembly 2 and a clock assembly 4, the drive mechanism 1 is transmitted to the clock assembly 4 through the linkage assembly 2, and the linkage assembly 2 is used to act as Reduction transmission; the linkage assembly 2 includes a counting assembly for counting the driving mechanism 1 , and the counting assembly is arranged on the output shaft of the driving mechanism 1 .

A conventional stepping motor acts on the clock component 4 through the output shaft, thereby driving the clock component 4 to work, and a clock structure of a stuck clock in this embodiment integrates the drive mechanism 1, the linkage component 2 and the clock component 4, The driving mechanism 1 is transmitted to the clock assembly 4 through the deceleration of the linkage assembly 2, and the counting assembly counts the working state of the driving mechanism 1, thereby achieving the effect of replacing the stepping motor. Since the stepper motor does not need to count its own working status, a lower-cost motor can be selected, thereby reducing the cost, and the clock structure is more cost-effective.

Specifically, since the stepper motor will have relatively large vibration during the working process, and it is easy to lose steps, resulting in noise on the clock face, or inaccurate positioning, so in this embodiment, the driving mechanism 1 adopts a DC motor, linkage assembly 2 also includes the combination of worm wheel 22 and worm screw 21, and described linkage assembly 2 also includes worm wheel 22 and worm screw 21, and described worm screw 21 is arranged on boss 32, and the input of described worm wheel 22 and clock assembly 4 The shaft is connected, and the worm gear 22 is engaged with the worm screw 21; the worm screw 21 is driven by a DC motor, and the worm screw 21 is engaged with the worm gear 22, and finally the clock assembly 4 is input by the worm gear 22 to realize the deceleration of the DC motor drive. Preferably, in order to achieve an optimal transmission ratio, the worm 21 includes multi-layer threads, and the pitch of the threads is not greater than 2 mm.

Specifically, the counting assembly includes a counting optocoupler, a boss 32 and a bump 33, the boss 32 is connected to the output shaft of the drive mechanism 1, and the bump 33 is located on the boss 32; the counting optocoupler Located on one side of the protruding block 33 , the boss 32 and the protruding block 33 are integrally formed. Through the rotation of the output shaft of the drive mechanism 1, the rotation of the boss 32 is driven, and the protrusion 33 is also rotated under the drive of the boss 32. At this time, only the number of rotations of the protrusion 33 needs to be counted by the counting optocoupler. And knowing the positions of the minute hand and the hour hand, the same technical effect as that of the stepping motor can be realized. Because the position of the counting optocoupler needs to be adjusted according to different clock models; in addition, the optocoupler is used as an example to illustrate the principle of action. In fact, magnetic induction, optical induction, mechanical induction, etc. can also be used to detect the bump 33 The scheme of the number of turns is also the preferred scheme of this embodiment.

In this embodiment, the driving mechanism 1 and the linkage assembly 2 work in cooperation with each other, and the cooperation of software and electronic hardware can achieve high-precision positioning compared with stepping motors, without losing steps, without vibration and noise, and at the same time DC The price of the motor is still relatively low.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art Personnel should understand that the technical solution of the utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solution of the utility model.
