Specific embodiment

Illustrate the embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this theory Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition Different specific embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer With carrying out various modifications or alterations under the spirit without departing from the utility model.

It should be noted that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate The bright revealed content of book is not intended to limit the utility model implementable so that those skilled in the art understands and reads Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, In the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in disclosed in the utility model Technology contents obtain and can cover in the range of.Meanwhile in this specification it is cited as "upper", "lower", "left", "right", " in Between " and " one " etc. term, be merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, Relativeness is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.

As shown in Figure 1, a kind of timing topology of card clock, including driving mechanism 1, linkage unit 2 and clock assembly 4, institute It states driving mechanism 1 and clock assembly 4 is driven to by linkage unit 2, the linkage unit 2 is for making deceleration transmission；The linkage Component 2 includes the counting component for making to count to driving mechanism 1, and the counting component is set to the output shaft of driving mechanism 1.

Conventional stepper motor is that clock assembly 4 is acted on by output shaft, to drive the work of clock assembly 4, and A kind of timing topology of card clock of the present embodiment, is integrated with driving mechanism 1, linkage unit 2 and clock assembly 4, driving mechanism 1 By the deceleration transmission of linkage unit 2 to clock assembly 4, and counted by working condition of the counting component to driving mechanism 1, To achieve the effect that replace stepper motor.The working condition of itself is counted due to not needing stepper motor, i.e., it is optional It is selected to this lower motor, to reduce cost, the cost performance of the timing topology is higher.

Specifically, be easy to lose step since to occur such as synchronizing operational shock during the work time bigger for stepper motor, Clock face is caused to have the situation of noise or position inaccurate, therefore in the present embodiment, driving mechanism 1 uses direct current generator, Linkage unit 2 further comprises the combination of worm gear 22 Yu worm screw 21, and the linkage unit 2 further includes worm gear 22 and worm screw 21, described Worm screw 21 is set to boss 32, the input axis connection of the worm gear 22 and clock assembly 4, and the worm gear 22 is engaged with worm screw 21；It is logical It crosses direct current generator to be driven worm screw 21, worm screw 21 engages with worm gear 22, finally carries out clock assembly 4 by worm gear 22 defeated Enter, realizes the deceleration of DC Motor Drives.Preferably, in order to realize optimal transmission ratio, the worm screw 21 includes multilayer screw thread, The screw pitch of the screw thread is not more than 2mm.

Specifically, the counting component includes counting optocoupler, boss 32 and convex block 33, the boss 32 and driving mechanism 1 output axis connection, the convex block 33 are set to boss 32；The optocoupler that counts is located at the side of convex block 33, the boss 32 and Convex block 33 is integrally formed.By the rotation of the output shaft of driving mechanism 1, the rotation of boss 32 is driven, convex block 33 is in boss 32 Drive it is lower also the same realize rotation, need to only be counted and be learnt by turnning circle of the counting optocoupler to convex block 33 at this time minute hand, Technical effect identical with stepper motor can be realized in the position of hour hands.Position due to counting optocoupler is needed according to different Card bell number adjusts position；In addition, this sentences optocoupler as an example to illustrate operating principle, reality can also use magnetic induction, Photoinduction, mechanical sense answer etc. can play detection convex block 33 enclose number scheme be also the present embodiment preferred embodiment.

In the present embodiment, driving mechanism 1, linkage unit 2 cooperate with each other, and matching by software and electronic hardware It closes, compared with stepper motor compared to high accuracy positioning is realized, step will not be lost, do not have vibration noise, while the price of direct current generator is also It is cheaper.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
