Description

24 o'clock digital rings that indicate the upper and lower noon make day, go through synchronous link gear week

It belongs to light industry clock and watch technical field " 24 o'clock digital rings that indicate the upper and lower noon make the diurnal go through synchronous link gear " the utility model.

The utility model designs on 90225601.7 patent bases, therefore they all have periphery and are evenly equipped with 0～11,12～23 liang of periods are corresponding interts 24 o'clock digital rings of arranging and 12 windows of dial plate correspondence, but de-rotation by digital rings, make window 24 o'clock meter reading mechanisms that 0～11,12～23 liang of concrete numerical value of period come occur.The utility model has been set up on this basis and can have been expressed the link gear that " AM in the morning " " PM in afternoon " and diurnal go through at dial plate newly-installed two rectangular windows.The upper and lower noon also can be called " half day " to be gone through, and the clock and watch that the upper and lower noon of this expression is provided with see that effect is the same more in the quartzy liquid crystal display clock and watch of the third generation.By day, month graphic change is represented also once the occurring of upper and lower noon of half a day, and is " snail-like movement " in mechanical clock.The utility model diurnal is gone through with traditional clock and watch day-date effect the same, and the particularly selection of window shape position makes people feel the traditional of clock and watch of the present utility model, and is not strange.Because the main part of the utility model all is the organic glass acrylic material, so, having constituted the perspective display effect that the diurnal goes through, its same wrist-watch (alarm clock) Graphics Application transparent film " second hand " gimmick is similar.This diurnal is gone through on structure, total arrangement and part form and effect, quantity is with the clock and watch broadly similar of market sale now, day-date as development area, Tianjin Taida board crystal clock, it is that snail-like movement is dialled soon, distinguishes controll day, Zhou Lihuan by two shifting blocks, crosses and goes through low precision, this diurnal is gone through with a shared moving shifting block, and controll day, Zhou Lihuan made and spend week day also on time synchronously.

Meter reading (clock) mechanism during 90225601.7 digital ring types 24 of design at that time, focus in 24 o'clock the performance, and performance in 24 o'clock is inevitable on 12 o'clock basis, the utility model is exactly with the link gear set up wherein 12 o'clock drive connections and feature to be showed, formed 12: 24 o'clock complete contrast meter reading mechanisms of these clock and watch, made these type of clock and watch become people's can read whole day " round-the-clock " clock and watch of time whenever.The utility model is simultaneously also crossed and is crossed that day precision is not high designs week for solving clock and watch.This reality have novel purpose be exactly the clock and watch of meter reading mechanism when making digital ring type 24 with distinctive transmission mechanism, set up 12 o'clock common all functions of meter reading: " half day " of representing the upper and lower noon gone through, calendar, Zhou Li.

The utility model is to adopt reversible micro motor to do the independent power source, changes power of motor and can make big clock and watch arbitrarily.Motor makes the part have 24 o'clock digital rings of modulus tooth along de-rotation along de-rotation by speed reduction unit.Can make when clockwise 24 o'clock digital rings periphery uniform on, be arranged in 0 (12), 12,1 corresponding interting of segment value in the at 2 o'clock in afternoon, 13,2,14,3,15,4,16,5,17,6,18,7,19,8,20,9,21,10,22,11, in 24 numerals of 23 ordered series of numbers, 12,13,14,15,16,17,18,19,20,21,12 numerals of 22,23 are outside 12 windows of dial plate periphery show, and the rectangular window with traditional day-date window symmetry that " PM in afternoon " that inboard 21 o'clock places of 24 o'clock digital rings numerals indicate sets from dial plate gets and shows.When 24 o'clock digital rings reversed, 0,1,2,3,4,5,6,7,8,9,10,11 outside 12 windows of dial plate periphery were represented, " AM in the morning " that indicates at inboard 9 o'clock places of 24 o'clock digital rings show.Also will realize a kind of function of the design during reverse, that is exactly the conversion of going through in the diurnal.This day, go through in week be provided with mainly be marked with the moving shifting block set up at 16 numeral places and its control behind by 24 o'clock digital rings with coaxial date rings and Zhou Lihuan and day of 24 o'clock digital rings, go through the loop mapping ratchet week and formed.This date rings is that outline has 31 ratchets, and the ratchet front is marked with 1～31,31 numerals in inboard this mean line of ratchet on date rings 31 mean lines.Same Zhou Lihuan has 28 its inboards of outer ratchet to indicate 28 days Zhou Li all around, and promptly four of Monday～Sun. are end to end.Diurnal is gone through ring ratchet tooth tip circle and equates that tooth depth is identical.It is that two connecting rod forms are formed that diurnal is gone through the location ratchet, and it had both played separately diurnal and has gone through the location of ring, can manually cross again day or all excessively.The design only calendar ratchet adopts this form to do to begin daily by the moon.Its original position of day weekly calendar arrangement is to go through the ring ratchet diurnal to arrange in the same way, corresponding ratchet front overlaps at the dial plate transverse axis forward, be on the center line of day-date window, the front of the moving ratchet of 24 o'clock digital rings of the day of effect at this moment, Zhou Lihuan should be that the transverse axis forward is on the 15 ° of angle lines that turn clockwise of initial line.And the ratchet front that is positioned in the date rings of day-date window should be that 360 °/31 promptly 11.613 ° and Zhou Lihuan are 360 °/28 promptly 12.319 ° to its last ratchet front angle value.When digital rings reverses when 24 its with the idle running of moving shifting block front begin to promote Zhou Lihuan ratchet front for 2.681 °, for the date rings 3.387 ° of promotion date rings ratchet fronts of will dally.During 15 ° of digital rings revolutions, date rings has changeed 11.613 ° when 24, and Zhou Lihuan has changeed 12.319 °, and promptly each crosses a tooth, and promptly each spends one day, puts in place synchronously at the day-date window.The rule of obvious this method should be a/2＜r, B≤a, and a definite value is that 15 ° of (digital rings was changeed the width of cloth in 24 o'clock) 11.613 ° of (31 days calibration of date rings) r of B definite value are variate, the design selects 12.319 ° to be that 28 days calibration of Zhou Lihuan are for best.When digital rings was clockwise when 24, it is motionless under location ratchet locking separately that the diurnal is gone through ring, and the diurnal is gone through constant, and 24 o'clock digital loop-backs are to reference position, does next and change to change day and prepare in week.Obviously be 24 hours day-date transformation period in diurnal, need 24 o'clock digital rings along de-rotation each once.And upper and lower noon during window name section and corresponding numerical transformation cycle period be 12 hours.

The utility model reversible electric machine control signal, it by 24 hour wheels (current day-date clock and watch all have, dial the sun) with symmetrical cam touch respectively constantly 0 o'clock, 12 of clock and watch that the corresponding contacts of phase-veversal switch obtains in the circuit.24 o'clock digital rings are changeed 15 °, the spacing original paper that changes the width of cloth be two separately and have the limit switch (normally closed) of opposite polarity diode to form, constitute two normally closed switchs on unidirectional circuit separately.When a limit switch is opened a way, himself and diode will form with another limit switch and treat that the conducting loop waits, wait the marquis to inversion signal make the motor rotation by this loop.Increased by two manual microswitch control motor positive and inverses and auto-manual switching toggle switch in the convenient test circuit for adjusting, it will be made the test board circuit and use part.

For showing this structural circuit characteristic, 2 light emitting diodes are housed in appearance, in 0: 12 red constantly green conversion.

It is that (Zhou Lihuan) material makes the fixed numeral of each ring gauge for 24 o'clock digital rings, date rings, and printed words can both show from the dial plate respective window after overlapping perspective " three rings " that sample of the present utility model adopts transparent organic glass acrylic board.

For cooperating this mechanism, with the inboard corresponding mark I～XII of 12 windows that meter readings in 24 o'clock of dial periphery are used, 12 Roman numbers (at upper and lower noon window, day-date window place can not mark), also symbol such as available relevant letter replaces certainly.Make these type of clock and watch like this with this mechanism, under indicator and dial scale cooperation, two rectangular windows in the inboard scope of dial plate I～XII are read date rings, Zhou Lihuan, 24 o'clock digital rings mark on it: i.e. x day, week x, the morning or afternoon and x point x minute and x second are when numeral can be read 24 o'clock x in I～XII outside 12 windows and x minute x second.

In sum this reality have novel when not only having increased by 902256017 digital ring types 24 two the functional representation upper and lower noons and the diurnal of meter reading mechanism go through conversion, and variation has also taken place in appearance, the rectangular window of this two function and the Roman number of I～XII mark, all be arranged on the dial center, the utility model that is subordinated to 90225601.7 patents has but been become main image, and a kind of function that meter reading mechanism has become these clock and watch when making digital ring type 24 appears at the dial plate periphery.Particularly 90225601.7 patented technologies are 24 o'clock single meter reading modes, and 12～23 meter readings constantly are more obvious in the afternoon.We know that meter reading in 12 o'clock is the clock and watch foundation, so the utility model emphasis also is the control systems that these clock and watch is formed took into account in 12: 24 o'clock, cover all at one glance from dial plate, and the market was not met.The quantity of dial plate hollow out window can claim it is the first in the world.And the conversion in all windows realizes fast in interlock that all precision is better than the market clock and watch in these clock and watch.Find out advantage of the present utility model by above-mentioned, its structure and implementation method have obvious difference for general day-date, the day-date of general clock and watch all is to be realized by a covering device separately, its structure type can be divided into instantaneously changing, climb soon, snail-like movement three classes, the day-date of this mechanism belongs to the instantaneously changing class from numeric character in the conversion rate of showing window.The main part of general typical instantaneously changing structure is by spring, shifting block, and pressure head is formed.The implementation method of day, Zhou Li is to do wink moving part promotion shifting block by spring, and shifting block is stirred date rings or Zhou Lihuan, but generally less than the position, does the corner compensation by pressure head again, makes pressure head not only play the location but also increase the corner effect.And the spring part of this structure also is moment when easily influence is walked.Current general clock and watch all are fast, snail-like movement structure in fact, day, count word exchange gradually in showing window week one by one.Climb day, go through in week conversion soon and need 15 minutes, snail-like movement needs 3 hours, and what its design accuracy adopted is the principle of concludeing a contract or treaty that custom becomes: spend Sunday night, and client's approval just can.And the real synchronous clock and watch of day-date are not seen at present.Design proposal of the present utility model is to adopt a covering device, and the transmission actuator is a cover, and a shared shifting block acts on day successively, Zhou Lihuan and satisfy its different corner requirement, makes day, goes through in week that synchronous conversion realizes.Therefore this mechanism mainly passes part does not have elasticity, is again the independent power source, and moment is unaffected when walking, and pressure head need not have the corner compensate function, unique easy, reliable, quick, the synchronous advantage so this mechanism has any different in general clock and watch day-date.

It is that the utility model outside drawing also claims watch face figure for a Figure of description 1.Have Roman number I～XII to represent integral point in the calibration loop in second, there is traditional day-date (diurnal is gone through) window on (level place there be not mark) horizontal right side, left side and its symmetry be the window at upper and lower noon of expression, what cooperate formation at indicator is 12 o'clock meter reading systems.Be that to have 12 windows shown be upper and lower period of the day from 11 a.m. to 1 p.m of piece of digital on 24 o'clock digital rings for 24 o'clock meter reading zones outside dial plate calibration loop second.Red, the green light emitting diode that shows usefulness when the figure lower left corner is 0: 12 o'clock this mechanism action.The A-A section is by Fig. 3 display structure.

Accompanying drawing 2 is " watch face " structural drawing that remove dish, pin.Because the part material that this mechanism characteristicness is selected nearly all is the transparent organic glass acrylic, so composition is all handled by the visible solid line bar of perspective.Part 3 is 24 o'clock digital rings, also has " AM in the morning " and " PM in afternoon " printed words above except that indicating 24 numerals, part 7 be 24 o'clock digital rings back side itself with moving shifting block.Part 5 date rings of assembling coaxial below part 3 with it, date rings has 31 outer ratchets, and part 6 Zhou Lihuan have 28 outer ratchets, and part 8 is to go through the loop mapping ratchet week, and part 4 is two link-types location ratchets of date rings.Be illustrated as the original rigging position of this mechanism, part 5 has a pair of ratchet front to overlap on horizontal axis with part 6, and promptly on the line of symmetry of day-date window, from then on the window phantom outline can be read Monday, 17 days, on another, afternoon window to read the period of correspondence in afternoon be 12～23.Location date rings when part 4 is flat, when begin by the moon day, can promote preceding bar that sliding bar makes the band ratchet swing and stir the date rings ratchet cross a tooth one day, reset then.

Part 1 is that its drive speed reduction unit actuator 3 of reversible electric machine reverses, and the part 7 on the part 3 reverses thereupon, and part 7 moving shifting block front extended lines and transverse axis angle are 15 degree.When reversing beginning is idle running, and at first impeller 6 is that week calendar wheel ratchet front part 7 continues to reverse the ratchet front of impeller 5 date rings simultaneously then.Shift them onto transverse axis always, the Zhou Li, the calendar synchronization that mark on the two ratchet front extended lines are put in place, day-date is shown at this figure imagination window.When part 1 makes part 3 clockwise, part 7 moving shifting blocks will slip over part 5, part 6 one external ratchets, and at this moment part 5, part 6 are motionless under retraining at part 4, part 8 location ratchets " non-return ".Part 7 is got back to reference position with part 3.Part 2 is spacing normally closed switch (same with Fig. 4 K41, K42).

Fig. 3 is that this mechanism side is cutd open structural drawing (Figure 1A-A sectional view), and part 9 is quartz clock movements, and part 10 is movement clips, and part 6 is week calendar wheels, and part 5 is date wheels, and part 3 is 24 o'clock digital rings, all is transparent acrylic board.Part 11 is aluminium clock dials, and part 12 is that 24 o'clock gears (dialling the sun) are the symmetrical cams at the center of being symmetrical in axis cam.Part 13 be phase-veversal switch it formed by two contacts, corresponding trigger interval was put 12 hours by part 12 cam two-supremes in two contacts.

Fig. 4 is that circuit diagram K1 is the double-contact phase-veversal switch, and K21, K22 are that use switch, K3 be that the dpdt double-pole double-throw (DPDT) toggle switch also is a debugging usefulness for dpdt double-pole double-throw (DPDT) debugging.K41, K42 are spacing normally closed switch, and D01, D02 are light emitting diode, D reversible dc micromotor.K1 at first do not read by this circuit diagram and to its power supply, K3 has switched in debugging mode.Whole circuit is idiostatic, presses the K21 direction of current from the K3 upper slitter, and D03, K41, D01 flow through, and cutter returns negative pole under cutter K22 under the K3 from K42 (D02, D04 are obstructed) by motor.Lift K21 and press anti-phase D02, K42, the D04 of promptly flowing through of K22 electric current, flow through K41 (D03, D01 are obstructed) through D and return negative pole through the K3 upper slitter.

When K3 switched to the circuit auto state, K21, K22 upper slitter were normally closed.K1 will alternately touch the K1 upper and lower contact at 24 hour wheels institute strap cam every 12 hours.Direction of current will return negative pole that K1 lower contact connect through motor D from K41 through D02, K42, D04 through K22 upper slitter path when touching upper contact, and at this moment D forwards to when making 24 o'clock digital rings requirement amplitudes, and limit switch K41 will be disconnected, the motor D stall.K1 returns to normal after the high point of cam after a while.Crossing K1 lower contact after 12 hours, to be touched direction of current be to return the negative pole that the K1 upper contact connects through D03, D01 (the K41 limit switch is disconnected) through motor D, K42 (D02, D04 are obstructed), D motor rotation K41 reset circuit state is constant, be rotated further disconnection K42 circuit is broken, motor D is stopped.

The utility model designs for Chronograph timepiece.Clock and watch market is very big, and particularly the turnout of clock ranks first in the world, and accounts for 80% of gross output.But cheap of low grade, its technology content of increase of improving the grade should be a direction.The medium-to-high grade clock and watch of the utility model suitable for producing are particularly realized more appropriate on crystal clock.Therefore designed as accompanying drawing 1 outside drawing of drawing towards crystal clock market exactly.

The big demand in market is just big, so process must adapt to batch production requirements.But clock and watch are again handicrafts appreciates product, so its appearance component otherwise lose its artistry adopts technology such as optically-active just better as dial.

The main original paper of these clock and watch all is an organic glass, so will select injection moulding process for use, the cost low velocity is fast.Also to carry out simple serigraphy after three rings of the present utility model (24 o'clock digital rings, date rings, the Zhou Lihuan) injection moulding and print out the numeric literal printed words.Three rings are transparent among the design.But it is transparent only selecting date rings in producing in batches, and two plates select transparent materials in addition.But consider that but 24 o'clock digital rings de-rotation can not block the day-date printed words that date rings and Zhou Lihuan perspective present in projection place of dial plate day-date window, therefore should " hollow out " outside the Pass mutually.Zhou Lihuan is injection molded into opaque, can make the day-date printed words foil at milky or the pearly-lustre look upper base of Zhou Lihuan itself.So just simplified this two ring if the enamelling process of selecting transparent panel for use and the opaque position of requirement being arranged as Fig. 2, in " the AM morning " " PM afternoon " of 24 o'clock digital rings marks, will be painted behind.And the orlop that day-date window " Monday, 17 " is seen below is Zhou Lihuan, and it just has been end liner with space black as if transparent.Obviously weak effect some.

For solving the accuracy of circuit sampled signal, A among Fig. 3 separately vertically is placed on illustrated 12 cam level two symmetry places to two contacts of part 13 phase-veversal switches that diagrammatic sketch is represented.And part 12 cams are injection molded into gap form with single breach such as clock and watch warning wheel, but gap one side is modified as and connects best with the involute urve in 90 ° of calibration scopes.Rotate a circle with 24 hour wheels and act on two contacts of two phase-veversal switches at equally divided position respectively when cam like this, contact reed sudden change is resetted, and inversion signal is punctual rapidly produces.

Consider from the utility model one-piece construction and outward appearance, available on-deformable organic plates is placed on and goes through the ring back in 6 weeks of Fig. 3 spare, fastening with Fig. 3 spare 10 movement clips, make it can become the housing postnotum can play " bottom plate " effect again, moving part Zhou Lihuan, date rings, 24 o'clock digital rings are pressed the part 6 of Fig. 3, part 5, the side-looking order of part 3 is assembled on this plate, press again Fig. 2 level to day, each ratchet front of Zhou Lihuan and 24 o'clock numeral gyration shifting block fronts overlap, determine " three rings " head-down position, this position is this mechanism master reference position just, other relevant spacing part is also all determined locality according to this benchmark, as going through loop mapping ratchet and part 4 date rings two link-types location ratchet in 8 weeks of Fig. 2 spare.And the spacing normally closed switch of part 2 (2) (claim K41 in Fig. 4, K42) position limits even more importantly, and its is actual directly to influence this mechanism display effect.But 24 o'clock digital rings de-rotation, change 15 °, its 0 °, it on 15 ° of two positions the static show state of this mechanism, digital rings will illustrate the morning or afternoon and the corresponding concrete numerical value of period that itself marks at window in 24 o'clock, the day that assurance is arranged in the same way to ratchet during action, the unidirectional successively promotion of Zhou Lihuan, if certainly will influencing, 2 liang of spacing normally closed two contact position errors of part show digit position in the window, therefore the adjustment of 24 o'clock local modulus teeth of digital rings of part 2 distances both sides salient point is just very crucial as shown in Figure 2, and minute hand gets final product in the above-mentioned Fig. 3 spare of fine setting 13 amended two phase-veversal switch positions in the time of can installing before the dress dial plate.Treat after the final assembly timing knob behind the turn movement or press among Fig. 2 part 4 all interchangeable day, Zhou Li.For adjust go through in week convenient also can to make the two link-types location pawl structures of part 4 date rings among Fig. 2 into better going through the loop mapping ratchet in 8 weeks of part among Fig. 2.

For making in the simple and reliable production of circuit K21, K22, K3 among Fig. 4 are removed.By above consideration and sample arrangement, its effect will make clock and watch manufacturing accuracy of the present utility model and economic accuracy all more satisfactory, make the utility model practicality, novelty, perfect more with performance.
