Embodiment
The movement control system of the utility model radio wave clock as shown in Figure 2, comprises two step motor, two gear sets and two optical sensor elements.Microprocessor 13 is by two step motor of signal wire control, and promptly first step motor 21 and second step motor 25 make its independent operation separately.Two gear sets, promptly second hand wheel group 22 with the time minute gear group 26, driven by first step motor 21, second step motor 25 respectively.The time minute gear 27 in the minute gear group 26 drive hour hand gear 28 via reduction gearing, and then make when corresponding, minute hand moves.
In addition, the time, minute, second pin gear outer rim is respectively equipped with the perforation of light-permeable, is depicted as the vertical view of second hand wheel as Fig. 3 B, the second hand wheel outer rim has continuous two light-permeables perforation 31,32, and the spacing AB between these two perforation.Be respectively the vertical view of branch, hour hand gear shown in Fig. 4 B and Fig. 4 C, minute gear 27 is provided with the perforation 33~36 of four identical light-permeables, and hour hand gear 28 is provided with a perforation 37, and its size is more than or equal to the size of perforation 33~36.
Again, the optical sensor element is an element with the transmitting terminal that produces the emission light wave and the receiving end that receives this emission light wave.The first optical sensor element 24 as shown in Figure 3A, is located at a side of last gear 23 outer rim that second hand wheel group 22 driven, and whether the perforation that is used for detecting this gear is to anchor point and produce corresponding position calibration signal; And the second optical sensor element 29, shown in Fig. 4 A, whether a side of the minute gear 27 of minute gear group 26 and hour hand gear 28 outer rims when being located at, the perforation that is used for detecting minute gear 27 and the perforation of hour hand gear 28 be simultaneously to anchor point and produce corresponding calibration signal.When making zero the location, shown in Fig. 3 A and Fig. 3 B, second hand wheel 23 rotates and makes perforation 31,32 enter the first optical sensor element, 24 valid analysing ranges successively.Suppose to produce a low level signal when the first optical sensor element 24 detects less than the emission light wave, shown in Fig. 5 A, at time point t
1All be the low level signal, when anchor point was arrived in the perforation 31 of second hand wheel 23, the first optical sensor element 24 just can detect the emission light wave and produce a high levels signal (t before
1~t
2), second hand wheel 23 is rotated further, and as AB during at anchor point, the first optical sensor element 24 detects less than the emission light wave and produces a low level signal (t
2~t
3), then, when anchor point was arrived in perforation 32, the first optical sensor element 24 produced a high levels signal (t again
3~t
4), afterwards, the first optical sensor element 24 promptly produces the low level signal.At time point t
2Before, first step motor 21 is to run up, when microprocessor 13 detects first pulse (impulse), just control first step motor 21 and reduce to low-speed running, when detecting second pulse, microprocessor 13 notifies first step motor 21 to shut down, the stable immediately position of also accurately getting back to zero second of second hand pointer this moment.
As for the time, minute gear 28,27, shown in Fig. 4 A-Fig. 4 C, both parallel runnings, overlapping up and down, when just locating, anchor point is got back in perforation 37 earlier, and minute gear 27 remains in operation, when the perforation 33 forward to the perforation 37 directly over the time (as Fig. 4 D), make the emission light wave that sees through perforation 33 also be continued unhinderedly to see through perforation 37, shown in Fig. 5 B, just the second optical sensor element 29 can detect the emission light wave and produce a high levels signal (t
11~t
12), minute gear 27 is rotated further, and when minute gear 27 covers perforation 37 the time, the second optical sensor element 29 detects less than the emission light wave and produces a low level signal (t
12~t
13), then, perforation 34 forward to perforation 37 directly over the time, the optical sensor element produces a high levels signal (t
13~t
14), by that analogy, produce four pulses altogether.At time point t
12Before, step motor is to run up, when microprocessor 13 detects first pulse, just control second step motor 25 and reduce to low-speed running, when detecting the 4th pulse, microprocessor 13 just stops the running of second step motor 25 fully, the time, the minute hand pointer is also stable and the position of zero when accurately getting back to zero, when finishing, minute hand returns the task to anchor point.
The utility model is when making assembling, utilize an optoelectronic switch fixed mount 62 (as Fig. 6 A) that is connected in radio wave clock lower cover 63, by this optoelectronic switch fixed mount 62, make the first optical sensor element 24 that is welded in a printed circuit board (PCB) (printed circuit board) 61 simultaneously and the second optical sensor element 29 when embedding, can find fast respectively on the second hand wheel 23 with the time minute gear 28, the relative position of the perforation on 27 is to quicken the assembling speed of production.Fig. 6 B is the three-dimensional exploded view of Fig. 6 A.Again, the first optical sensor element 24 and the second optical sensor element 29 also can wiring (wiring) mode be connected to the internal circuit of radio wave clock respectively.
The principal character of the movement control system of the utility model radio wave clock is two step motor, the independent simultaneously running of minute hand, second hand when dual inductor makes, and finishes the location with the acceleration radio wave clock and makes zero.In addition, a plurality of perforation on second of the present utility model, the minute gear, two sections speed designs of step motor uniqueness in the position fixing process that makes zero have been merged, gear is not before the anchor point, when running up, motor makes zero to quicken the location, during near anchor point, motor slowly runs, and gear is reduced rock to receive pinpoint effect.So in fact the utility model has had concurrently fast and the two big advantages of precisely locating.
The above only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this.Be that all equalizations of being done according to the utility model claim change and modify, all should still belong in the scope that the utility model patent contains.
