An electronic timepiece that converts intermittently driven rotation into continuous rotation of the pointer. The energy of continuous rotation is stored by using a hairspring or two magnets as an energy storage device, and then by using a pendulum and an escape wheel or immersed in a viscous The rotor in the liquid is used as a control device, so that the intermittent rotation is transmitted through the transmission part in a continuous manner to reach the pointer, so that the pointer rotates continuously. The invention simplifies the structure, reduces the volume and becomes thinner, and can absorb external impact. When the independent control When the device is disassembled, the gap rotating pointer movement is restored, so it is convenient for repair and assembly, and can simultaneously produce hour hands of different pointer movement types.
Description
The present invention is generally at the time meter that continuous pointer action is arranged, concrete relevant a kind of analog electronic chronometer, will the time the intermittent action counted change the steadily action continuously of pointer into.
Referring to Fig. 1, have and for the moment count it and totally be masked as 100, its structure such as Japanese patent gazette 56-47512 number announcement.Time meter 100 only shows relevant partial cross section, and a power train 101 is arranged, and letter is shown in the drawings, pivot 105 between power gear 102 and power pinion wheel 109 usefulness mainboards 117 and the gear train bridge plate 123 and 119 supports.Pivot holder 121 on the pivot 119 usefulness mainboards 117 supports that mainboard 117 usefulness screws 112 are fixing.
Pinion wheel 109 drives the 3rd gear 122 and the 3rd gear 122 fixing third pinions 110 supported with pivot 106 and drives minute wheel 108.Be the continuous action that produces second hand or scan second hand, power pinion wheel 109 drives initiatively magnet 115.Initiatively magnet 115 usefulness magnet frame 114 support that magnet frame directly is connected with driver pinion 109.One first is immersed in a kind of viscosity liquid 113 from moving magnet 116, thereby rotation is produced viscous resistance.First supporting plate 120 supports on moving magnet 116 and the viscosity liquid 113 usefulness mainboards 117.First from the suction driving of moving magnet 116 by active magnet 115.Second drives from moving magnet 116 from moving magnet 118 by first.Second shows that from moving magnet 118 and second hand axle 111 is connected.So, have the traditional analog electronic chronometer of intermittent timing action just to make pointer do continuous action like this.
When this type traditional in the meter, the time meter the storage rotating energy part and discharge the part of rotating energy gradually, forms an element, exactly active magnet and be an element from moving magnet.This may cause some problems.If will change from the size and the configuration of moving magnet, to change energy stored, the viscous resistance of viscosity liquid is also tended to change so, therefore causes the instability action of the jump of pointer.On the contrary, if change from the gap size between moving magnet and the mainboard, then the size of magnetic attraction is tended to change.
It is the initiatively magnet and first angle from moving magnet on the one hand that phase differential changes, and is first from the moving magnet and second variation from the angle between the moving magnet on the other hand, produces the suction that makes progress along magnet shaft or the variation of repulsive force.Cause magnet like this, especially shown in Figure 1 first from moving magnet, moves up and down in the limit in the gap that viscosity liquid provides.First from the activity of moving magnet the hole of viscosity liquid, changes first viscous resistance from the moving magnet action.And the orientation of change magnet, friction is changed because of the direct friction between thrust and the first driven magnet edges and the mainboard.So cause the unevenness of rotation.
In addition, during type shown in Figure 1 traditional in respect of multilevel hierarchy, the thickness of meter when being difficult to reduce, and make and do not have enough spans between two bearings.The support instability of the axle of supporting pointer, pointer tends to do disadvantageous canting during running.
Another problem of traditional structure is the sine wave relation between magnet suction and the corner.As a result, when active magnet and first from the angle between the moving magnet, or first when initiatively the angle of magnet and second between moving magnet is greater than 90 °, when then the deviation of angle increases, reset force just reduces, and magnetic systems just can not correctly be worked, with the rotation of control from moving magnet.When the angle between two magnet is about 0 ° or 90 °, the variation of reset force is just arranged when only the angle between magnet changes, therefore can not obtain speed control in company with reaction.Observe the sinusoidal wave camber line of 0 ° or 90 ° and can see that when angle changed, the amplitude of rate of change was very little at every turn.So, because viscosity load fluctuation or variation, when the angle between two magnet is 0 ° or 90 °, effective control rate.
Under physical condition, there are many power to cause fluctuation and the viscosity load or the viscosity fluctuation of magnet suction because of size out of true and uneven magnetization.These stress in the system may cause initiatively and from the angle between the moving magnet once in a while greater than 180 °.In these cases, not only from the correct control rate of moving magnet, and rotation in fact round about.Therefore indicate the incorrect time.
And,, between magnet and stepper motor, have magnetic force to disturb because magnet rotates at Shi Jizhong.As a result, element is furnished with serious restriction.In addition, in traditional arrangement, require viscosity liquid that very high glutinousness is arranged during the slow-speed of revolution,, have how many pointers just to require rotary magnet with number to obtain the high viscosity resistance.The cost of meter and the difficulty of assembling when this has just increased.
Therefore, need improved time meter, with the circuit of timing and the intermittent action of stepper motor, change into the continuous action of pointer, both reliable, effectively, internally external carbuncle is insensitive, and compact conformation, and easily repairing can be used for meter when slim.
The present invention can do rotation continuously with pointer with intermittent driven in rotation reaction generally at a kind of electronic chronometer.Stored energy mechanism of Shi Jiyou is connected with intermittent driven in rotation, and intermittent driven in rotation is become storage power.A control gear discharges the energy of rotation that stores continuously and becomes continuous rotation.A bindiny mechanism connects between stored energy mechanism and control gear, with continuous rotary motion from stored energy mechanism to the control gear transmission.Pointer is connected with bindiny mechanism, and what pointer was provided scans action continuously.
Therefore, purpose of the present invention is to propose a kind of improved electronics hour hands, will the time step drive mechanism counted become continuous pointer and scan action.
Another object of the present invention is a meter when proposing a kind of improvements, will the time the intermittent spinning movement counted, the accumulator system that utilization and control gear form respectively, what change pointer into scans action continuously, to produce substantially invariable rotatablely moving.
Another purpose of the present invention, be to propose a kind of improved analogue type electronic chronometer, its stepper motor makes it intermittently rotation by the reference signal signal supplied, drive indication mechanism and show the time, there is stocking mechanism to store the energy of rotation of stepper motor, and control gear is arranged, and releasing pattern is for stablizing the energy of rotation that rotatablely moves gradually, and stocking mechanism and control gear are arranged respectively in electronic chronometer.
A further object of the invention is to propose the electronic chronometer of a kind of improvement analogue type, its signal that utilizes the reference signal frequency division to obtain is made the intermittently stepper motor of rotation, drive an indication mechanism by the mode of scanning continuously, utilize a hairspring to store the energy of rotation of stepper motor, and a rotor in the viscosity liquid arranged, by continuous substantially mode, the release of control energy.
A further object of the invention, be to propose a kind of analogue type electronic chronometer, the stepper motor that it rotates with the signal break that the reference signal frequency division is obtained, make control device with the magnetic catch members, driving indication mechanism scans continuously, make stocking mechanism from moving magnet for one first, with the stepping rotation of stepper motor, that changes into a pointer scans action continuously.
Other purposes of the present invention and advantage just can be had gained some understanding to a part after reading instructions, make a part more understandable.

Figure 20 is the block scheme of electronic chronometer function of the present invention.
At first referring to Figure 20, show by the present invention's structure the time 200.Time meter 200 has the reference signal frequency division of 201, one time base circuits 202 of a quartz oscillator with oscillator 201, produces the intermittent actuating signal that drives transducer 203.Transducer 203 is a stepper motor in desirable embodiment.Stocking mechanism 204 stores the energy of rotation that transducer 203 produces.Control gear 206 is by discharging gradually that the mode of steady rotation will store.Stocking mechanism is connected with control gear by gear 205.Gear 205 drives indication mechanism 207.
In the structure of the type that Figure 20 shows, stocking mechanism separates with control gear.As a result, by the present invention produce the time structure desirable characteristics can be arranged, the characteristics of size and thickness for example.In addition, stocking mechanism separates with control gear, can simplify repairing after the assembling.
Then referring to Fig. 2 and 3, show the electronic chronometer of representing overall first embodiment of the invention with numbers 210, Fig. 2 analyses and observe for electronic chronometer 210, and Fig. 3 overlooks for electronic chronometer 210.Time meter 210 has a coil 1, on the iron core 2 that stator 4 is arranged.Stator 4 drives rotor 5 by step-by-step system.With the 6th pinion wheel 6 of rotor 5 engagements, drive the 5th gear 7 with 8 engagements of the 5th pinion wheel.The 5th pinion wheel 8 drives the hairspring gear 9 that is connected with hairspring 10 1 ends.The end in addition of hairspring 10 connects hairspring pinion wheel 11.Hairspring pinion wheel 11 and idle pulley 12 engagements, idle gear 12 and 13 engagements of viscosity rotor pinion.Viscosity rotor pinion 13 and be placed in the cavity 19 and the viscosity rotor 14 that is immersed in the viscosity liquid 17 fixing.Viscosity liquid 17 is silicone oil in a desirable embodiment.Pointer 16 is connected with the 4th gear 15, and the 4th gear meshes by the 4th idle pulley 12 and viscosity rotor pinion 13, and by the speed ratio rotation corresponding with the gear number of teeth.The 6th pinion wheel 7 groups of shanks 23 of 6, the five pinion wheels, 8, the five gears and the idle pulley 12 of rotor 5 are installed between a gear train bridge plate 22 and mainboard 21.Viscosity rotor pinion 13 and viscosity rotor 14 are installed between gear train bridge plate 22 and the cavity spare 9a and rotate.Coil 1 usefulness screw 3 is fixing on mainboard 21.
Because the 4th gear 15 of band pointer 16, by the 4th idle pulley 12 and 13 engagements of viscosity rotor pinion, the 4th gear 15 is by the speed ratio rotation corresponding with the gear number of teeth.The shank 23 of dialling that hairspring gear 9 and hairspring pinion wheel 11 can center on coaxial cable respectively rotates.Hairspring gear 9 is connected with hairspring pinion wheel 11 by hairspring 10.
When rotor 5 was promoted by stepping, hairspring gear 9 was also done step-type rotation.But, still do the rotation stably that links up because hairspring pinion wheel 11 is subjected to hairspring 10 afterburning and around the control of the viscous resistance of the viscosity liquid 17 of viscosity rotor 14.Hairspring 10 allows stepping rotation hairspring gear 9 and rotates continuously that difference or angular displacement are arranged between the hairspring pinion wheel 11.Hairspring 10, gear train and viscosity rotor 14, it is moving to form a vibration system, and wherein viscous resistance is adjusted to bigger overdamping, thus even externally during altering a great deal in stress and the disturbance, system can effectively and reliably turn round.
Referring again to Fig. 4, show hairspring wrap angle h and hairspring reset force T
hRelation.Curve is shown in each step level of stepper motor, and hairspring is by angle θ
hThe torque T that resets required
hAnd obtain the relation of the increment △ T that wrap angle sigma/a needs.Fig. 4 also shows that hairspring has reached wrap angle
hThe time, cornerite increment α/a is to the influence of torque.From Fig. 4, can clearly see between reset force and cornerite linear relation being arranged.
Next step is referring to Fig. 5, when showing that counting pointer at that time scans, and promptly under constant speed continuously during smooth rotation, viscosity rotor velocity W
SLoad torque T with contrary viscosity rotor sense of rotation
hRelation.When the reduction gear ratio of the gear train between hairspring and viscosity rotor is b, angular velocity W
SAnd W
S+ △ W is equivalent to load torque bT respectively
hAnd b(T
h+ △ T).So, steady for guaranteeing pointer action, should reduce mark △ W/W
SJust reduce mark △ T/T
hAmong the △ T of a step level, store when hairspring under the condition of the torque relevant with some step levels, viscosity rotor speed is angular velocity W
S, therefore obtain angular displacement stably.For obtaining this effect, the elastic constant of hairspring 10 can be reduced, or the viscosity load that 17 pairs of viscosity rotors 14 of viscosity liquid apply is improved.
In above-mentioned structure, the viscosity rotor rotates in a constant speed, hairspring and load torque balance under this speed.The angular velocity of the load torque of viscosity rotor and viscosity rotor is directly proportional, thereby prevents hairspring pinion wheel velocity variations.So the stable action of pointer and constant does not have intermittent increment.
Even load torque changes with glutinousness, can obtain the action continuously and stably of pointer.Though the cornerite of hairspring increase and decrease is because hairspring is with desirable resilient material manufacturing, so the still maintenance action of scanning continuously.Even in this case, as long as stepper motor does not stop, pointer is rotated further.
Counted at that time 210 set up orthochronous after, the time meter running by control lever 20 controls, stop the action of the 4th gear 15, thereby stop the action of pointer and the action of viscosity rotor 14.But hairspring 10 is by elastic deformation when pointer action stops, in case control lever 20 is unclamped, pointer just recovers to scan continuously action.Counted 210 at that time when being subjected to fierce disturbance, so the extra rotation and the elastic deformation of viscosity rotor control hairspring 10 are the steady tram of display pointer.Because hairspring can provide opposing torque to rotor pinion 13, just can stablize outside disturbance, just can make to comprise viscosity rotor pinion 13, viscosity rotor 14, the gear train of idle pulley 20 and the 4th gear 15 is done the rotation of both forward and reverse directions.
Referring again to Fig. 6, the electronic chronometer 220 by the second embodiment of the invention structure is described.Similar components indicates with sign of similarity.The same with the time meter 210 in Fig. 2 and 3, electronic chronometer 220 is supplied with energy of rotation stepping or increment to hairspring 10.The revolving force to 11 transmission of hairspring pinion wheel of hairspring 10 is directly delivered on the 4th gear 15 that is engaged with.The angular velocity of viscosity rotor 14 controls the 4th gear 15, thus control hairspring 10 is by the energy release of rotor pinion 13.In this structure, the size of gear train can be reduced, and the compactedness and the cost of meter structure descends when improving.
In addition, because the element of the gear train that hairspring 10 and viscosity rotor are 14 (is a hairspring pinion wheel 11, the 4th gear 15 and viscosity rotor pinion 13) also work to transmit storage power, the power that hairspring 10 stores can prevent any loosening, thereby pointer 16 correctly turns round.
Below referring again to Fig. 7, the integral body of its electronic chronometer is with number 230 signs.Its structure is as described in the third embodiment of the invention.Similar components indicates with similar number.The 4th idle pulley 12 is set between the 4th gear 15 and hairspring pinion wheel 11, at the 4th gear 15(and coaxial with it demonstration pin 16) and hairspring gear 9 between be provided with a large amount of spacings, thereby improve the time count the dirigibility that 230 middle gears are arranged, the thickness when reducing.
Referring again to Fig. 8, show with number whole electronic chronometer of 240 signs, by the 4th embodiment structure of the present invention.Similar components indicates with the similar number of marking on a map.Between the 4th gear 15 and viscosity rotor pinion 13, idle pulley 12 is set, thereby in electronic chronometer 240, the 4th gear 15 and cavity 19 can be separated, improve the dirigibility that element is arranged, the thickness of meter when helping to reduce.
Referring again to Fig. 9, show with number 250 its whole electronic chronometers of sign and construct by fifth embodiment of the invention.Similar components is represented with the similar number of marking on a map.Fig. 9 is shown in increases some traditional element in the electronic chronometer, in order to simplify invention is narrated, and these elements omit in Fig. 2-3 and 6-8.A battery 16 is arranged, quartz (controlled) oscillator 35, circuit substrate 34 and timing integrated circuit 33 in the time meter 250.The drive waveforms of drive stepping motor rotor 5 by integrated circuit 33 and quartz (controlled) oscillator 35, provides to coil 1 by circuit substrate 34.A timing gear 24, bar 31 engagements during with running reaction of dialling shank 32 and school, and under to the running reaction of a deflection coil 30 and clutch gear 37 engagements.So just, can change the position of pointer.The 3rd gear 25 will slow down with the 4th gear 15 of second hand engagement, drives minute hand.Minute wheel 23 and timing gear 24 engagements.
Hairspring 10 usefulness tab 9a prevent to move axially.Groove 9c on the hairspring gear 9 that insert the end of hairspring 10 can transmit torque from hairspring gear 9 to hairspring 10.One the 4th idle pulley 12 is placed between hairspring pinion wheel 11 and the 4th gear 15, and is engaged with.A viscosity idle pulley 18 is placed between the 4th gear 15 and the viscosity rotor pinion 13.The 4th idle pulley 12 and viscosity rotor idle pulley 18 make each gear member and cavity 19 that bigger distance be arranged, and make it to leave mutually and the thickness of meter 250 when reducing.
Utilize structure shown in Figure 9, make viscosity rotor 14 and hairspring gear 9 be easy to arrange and do not stack, thereby make thin especially time meter easily, the invention is not restricted to the specific concrete arrangement of each element shown in the figure, and the element in the meter can be according to other of concrete needs and use the time is applicable to any proper arrangement.
Below referring to Figure 10, it represents overall electronic chronometer with numbers 260, and structure is as described in the 6th embodiment.Similar components indicates with the similar number of marking on a map.In time meter 260, make the angle energy that stocking mechanism storage stepper motor produces with hairspring 10, the viscosity rotor 14 of the viscosity load of toughness liquid 17 is used as control device.When shown the meter element remove pointer 16 and be used for pointer 16 on the 4th gear 15, installs spool outside, all between mainboard 21 and gear train bridge plate 22.Can form firm and thin time meter like this.Coil 1 drives rotor 5 by a stator 4, and magnetic core 2 forms a magnetic flux field, and hairspring pinion wheel 11 is connected with the opposite end of hairspring gear 9 with hairspring 10.Hairspring 10 is by the stepping of rotor 5 rotation, by comprising the 5th gear 7, the five pinion wheels 8 and hairspring gear 9 it taken up.The rotation of the 4th gear 15 is by the viscosity rotor 14 between gear train bridge plate 22 and cavity spare 19, by viscosity pinion wheel 13 and 26 controls of viscosity rotor idle pulley.
Hairspring gear 9 and hairspring pinion wheel 11 can rotate freely on coaxial, and the 4th idle pulley 12 and viscosity rotor idle pulley 26 are installed on the idler shaft 29 rotation, the rotation amplitude greater than with the loosening amplitude of the 4th gear 15 engagements.When rotor 5 being done stepping or intermittently driving, viscosity rotor 14 passes through the 4th idle pulley 12 with this structure, viscosity idle pulley 26 and the 4th gear 15, and the angular velocity of control hairspring pinion wheel 11, the load torque of viscosity rotor 14 is with angular velocity varies.Therefore, intermittently hairspring gear 9 that drives and the angular displacement between the hairspring pinion wheel 11 is made storage power by hairspring 10 absorptions, thereby hairspring pinion wheel 11 can be under the constant speed corresponding to hairspring 10 elastic deformation reset forces, rotation continuously and reposefully.
Referring again to Figure 11, show with number 270 electronic chronometers of representing in the overall seventh embodiment of the invention.Similar components indicates with the similar number of marking on a map.Magnetic catch members of electronic chronometer 270 usefulness is made control gear, and first makes stocking mechanism from moving magnet.An active magnet 51 is connected with driving gear 59, and rotation accompanies.Driving gear 59 is by rotor gear 6 stepper drive that are connected with rotor 5.First from moving magnet 52 and initiatively 51 of magnet a small distance is arranged.First is connected with driven pinion wheel 57 from moving magnet 52, and driven pinion wheel 57 is connected with an escape wheel 53.Driven pinion wheel 57 and the 4th gear 15(and the pointer 16 that is connected by axle 16a), connect by idle pulley 55 and loose pinion 55a.
The magnetic force that escape wheel 53 causes attracts the tooth of magnetization pendulum 54 to escape wheel 53.
The structure of escape wheel 53 and magnetization pendulum 54 is shown specifically in Figure 13.When escape wheel 53 because initiatively magnet 51 adds driving force and when rotating, pendulum 54 begins vibration first from moving magnet 52.Pendulum 54 vibrates under resonant frequency or other stabilized frequencies rapidly, and this frequency is started to control the rotation of escape wheel 53 and made usefulness and the gear train steering needle 16 by being attached thereto.
In this arranges, with the movement response of stepper motor, will regularly quantitatively apply to the first angle energy that applies from moving magnet 52, cause the pointer even speed and goodly scan action.Magnetic pendulum 54 has a fabricated section 54a, will put 54 and be installed on the mainboard 21, on the gear train frame dress plate 22 or other have on the structure of fabricated section 54b.Magnetic pendulum 54 vibrates (Figure 11,13) by specific frequency on the arrow A direction.Magnetic pendulum 54 does not directly contact escape wheel 53, and is more clear among Figure 13.The friction and the power pendulum that can reduce like this in the system lose as far as possible, improve the precision of the pendular oscillation of element 54.So just, improved the running accuracy of escape wheel 53 and pointer 16.
Referring again to Figure 12,14, show by the usefulness of eighth embodiment of the invention structure numbers 280 and represent overall electronic chronometer.Similar components is represented with the similar number of marking on a map.Pendulum 54 meter both sides of 270 when Figure 11 shows surround escape wheel 53, the time pendulum 56 in the meter 280 by two escape wheel 53a that form, 53b centers on.Pendulum 56 is used the magnetic material manufacturing, and leaf spring 56a uses fabricated section 56b fixed position.When pendulum 56 left the magnetic line of force of the attraction magnet 58 that is located between escape wheel 53a and the 53b, pendulum 56 was by magnetic attraction.This texture ratio uses Figure 11, and the magnetization pendulum in 13 produces the stronger magnetic line of force, thereby can obtain the continuous action more accurately of pointer.
When using the magnetic catch members shown in Figure 11-14 to make control gear, pendulum only is connected because of the tooth of magnetic force and escape wheel.Between escape wheel teeth and pendulum, there is not concrete contact.When pendulum by it during special or resonant frequency vibration, at the uniform velocity rotation is done in the outside force reaction that escape wheel is supplied with active magnet 51.So first stores the energy of rotation at intermittence that transducer (stepper motor comprises rotor 5) produces from moving magnet as the angular displacement with active magnetic magnetic 51, and under the control of pendulum, the driving force of doing of storage is discharged to escape wheel.So escape wheel rotates under basic even velocity, stops to supply with energy of rotation up to active magnet 51.Yet in case initiatively magnet 51 rotates again, the action of scanning of pointer begins again.At this moment, because frequency may be because load variations (being amplitude variations) slightly changes, even significantly frequency does not have through accurately adjusting, the angular velocity of escape wheel rotation was directly proportional with the load and the vibration period that attract magnet.Even the vibration period of pendulum changes because of outside input is arranged, when for example impact being arranged, magnetic connects disconnection, will store can discharge after, pointer is just stopped action.Then, in case rotor 5 recovers rotation, make initiatively magnet 51 rotations, the continuous rotation of pointer just begins again.Therefore, if initiatively magnet is driven by quartz oscillator and so on, just then will continue considerable time to the synchronous continuous drive of pointer 16.
Therefore, in the time meter shown in Figure 11-14 270 and 280, can obtain the uniform rotation of pointer, and unlikelyly power or vibration be had any injurious effects, even can thereby not make velocity variations because of the former of leakage and so on because of temperature.The pendulum and the not contact property of escape wheel teeth can be used for improving the durability of system, and reduce energy resource consumption, so accumulator or other batteries are counted can drive for a long time the time.
Next referring to Figure 15, show viscosity liquid type control gear.Similar components indicates with the similar number of marking on a map.A wheel rim 13e is arranged, one first opening 13f and one second opening 66, be located at a common axis of rotation integrally formed, and and the viscosity rotor pinion 13 of viscosity rotor 14 configuration in.A cavity 19 is formed by cavity chamber part 19a, holds viscosity rotor 14 and viscosity liquid 17.Cavity spare 19a has a groove 65 and a sloping portion 67.A lid 60 has in the Plug Division insertion groove 65, plays a part viscosity liquid 17 is limited in the cavity 19.Slope portion 67 helps viscosity liquid 17 is injected cavitys 19, does not make to overflow or splash.There is a flange part 60a in gap 60, is bent upwards and gap 61 of viscosity rotor pinion 13 formation.
The pinion shaft 13d of viscosity rotor pinion 13 is bearing in chamber support 19b and goes up rotation.Wheel rim spare 13e prevent viscosity liquid from tooth 13g that the first peristome 13f is connected spill chamber 19.Second peristome 66 increases the space, deals with because any thermal expansion of the viscosity liquid 17 that temperature variation causes.Groove 65 60 effectively is connected with lid, prevents that viscosity liquid from walking around the edge outflow of cavity 19.And, between the peripheral clearance 60 of groove 65 and space part 19a, make a kind of encapsulation process at least, prevent that from there is any leakage at the edge of surrounding cavity 19.Turn-up portion 60a also is used to prolong the length in gap 61 except that narrow gap is provided, thereby utilizes the resistance of long narrow gap to liquid stream, prevents the leakage by gap 61.
Referring again to Figure 16, show the viscosity rotor in another embodiment of the present invention and the subassembly of viscosity liquid, therein with magnetic liquid with cavity 19 sealings.Similar components sign of similarity code mark.Have opened gap 61 different with embodiment among Figure 15, and magnetic liquid 161 is placed in the gap 61, antistick characteristic liquid 17 flows out.An installation portion 19c on cavity spare 19a supports a york piece 63, york piece 63 supporting pivot framves 64, and and magnetic lid 60 push down magnet 62.Magnet shaft 13a magnetic material manufacturing is in order to make the turning axle of viscosity pinion wheel 13, with the friction torque of viscosity rotor 14 and viscosity liquid 17, to the remainder transmission of power train not shown in the figures.A magnetic field is arranged by york piece 63, pivotable frame 64, pinion wheel 13, axle 13a, lid 60 and turn-up portion 60a form, and magnetic liquid 161 is limited in rotor york piece 13b and covers in the gap 61 between 60 the turn-up portion 60a.In all structures as shown in figure 16, in a desirable embodiment, viscosity liquid can form with silicone oil, and magnetic liquid can form with fluorine solution, thereby prevents that viscosity liquid from flowing out the outside of cavity 19.
Referring again to Figure 17, show electronic chronometer by ninth embodiment of the invention structure, represent that with numbers 290 it is overall.Similar components sign of similarity sign.Time meter 290 usefulness such as active magnet and from the pair of magnet of moving magnet is made stocking mechanism, and is made control gear with a viscosity liquid subassembly.
The rotor 5 of stepper motor rotates with the current response of supplying with the coil 1 on the iron core 2 by stator 4.Driven active magnet 51 by the gear train that comprises the 5th gear 7, the five pinion wheels 8 and driven wheel 59 is storing as magnet 51 initiatively with from rotor 5 energy of rotations of the angular displacement between the moving magnet 52.When increasing from 0 ° to 90 ° when active magnet 51 with from the angular deviation between the moving magnet 52, the suction of magnet increases.The 4th idle pulley 12 and the 4th gear 15 that meshes with pointer 16, viscosity rotor pinion 13 and follower gear 57 engagements.Viscosity rotor pinion 13 is connected with viscosity rotor 14, and viscosity rotor 14 as above-mentioned is immersed in the viscosity liquid 17 of cavity 19.Magnet 51 and reset gradually initiatively from the angular displacement of moving magnet 52, and release energy gradually, as the rotational speed of the 4th idle gear 12 that is subjected to viscous friction control.As a result, pointer 16 rotates smoothly.
In the structure of time meter 290, will be supported between gear train bridge joint spare 22 and the mainboard 21 from moving magnet 52, thereby obtain enough spans and stability.And, because the 4th idle gear 12 separates with the 4th gear 15, just can make slim time meter, and do not produce in the prior art field the time meter the inclination of second hand scan.Stocking mechanism with magnet forms separates with the control gear of toughness liquid subassembly, and an advantage in addition is not have reciprocal influence, thus the assurance pointer reliably scan action continuously.
Referring again to Figure 18, show hairspring gear 9 of the present invention, the enlarged drawing of hairspring 10 and hairspring pinion wheel 11 structures.Similar components indicates with the similar number of marking on a map.Hairspring pinion wheel 11 has a hairspring connector 70 in the hairspring gear 9.Being configured to of hairspring 10 enlarges when application of load, and on chucking position 70a and web member 70 chuckings.The inner of bung flange hairspring 10 is stuck on the chucking position 70a.The outer end of hairspring 10 is connected with hairspring gear 9 in slot part 9c.Like this, just hairspring 10 is connected between hairspring gear 9 and the hairspring pinion wheel 11, thereby the elastic deformation of energy of rotation as hairspring 10 stored, the elastic deformation of hairspring 10 is decided by the angular displacement between hairspring gear 9 and the hairspring pinion wheel 11.Hairspring 10 moves axially along hairspring gear 9 and hairspring pinion wheel 11, is subjected to the projection piece 9a that also illustrates among Fig. 9 and the restriction of the sloping 9b of portion.The form of detent 11a in all cases, is for example swung sideward when moving when hairspring pinion wheel 9, prevents that hairspring gear 9 and hairspring pinion wheel 11 from contacting with each other.
This structure makes hairspring 10 be easy to assembling, because the friction load between hairspring pinion wheel 11 and the hairspring gear 9 is very little, this structure makes the action of scanning of pointer that good efficient be arranged.
Referring to Figure 19, show a part below by the semiconductor devices 300 of tenth embodiment of the invention structure.Similar components indicates with the similar number of marking on a map.Therefore the characteristics of electronic chronometer 300 when control gear is removed, can obtain the action intermittently that has of pointer for a detachable control gear is arranged.
Detachable control gear has cavity spare 19a, and cavity spare 19a covers 60, viscosity liquid 17 in the cavity 19 and viscosity rotor 14, and viscosity rotor pinion 13 subassemblies.Subassembly inserts the hole 81 on the mainboard 21, up to viscosity rotor pinion 13 and idle pulley 12 engagements, thereby makes the rotation of hairspring pinion wheel 11 be subjected to the control of viscous resistance.Interlocked usefulness with the catch members 80 of the notch part 67 of cavity 19 and the idle pulley 12 on the mainboard 21 prevents the rotation of cavity 19.
Therefore, control gear can be made optimization and form, and flexibly assembling and the time score Ce Shi not.Meter was convenient to repair when the detachable character of The whole control mechanism also made.At last, the pointer of meter has stepwise operation or scans action continuously when no matter requiring, the method manufacturing that time meter can be identical.If require pointer then can insert control gear with scanning action.Otherwise when not having control gear, in time, count with stepping pointer action running.When illustrated control gear is installed on meter 300 the mainboard side, but also can be installed in gear train bridge plate side, and can form by different shape and size.
Therefore, a kind of electronic chronometer stores intermittent energy of rotation, elastic deformation force as hairspring or other elastic components, or the suction between the magnetic material, then with the energy of rotation that stores, discharge by a control device gradually, Shi Jizhong is provided with a viscosity rotor and viscous resistance, or a magnetic catch members is arranged.In either case, stocking mechanism and control gear form respectively.Can make the stable action of scanning of pointer like this.Described specific embodiment shown in structure recited above is not limited to.In addition, the applicant's invention can the time count beyond the scope, be used for intermittent energy of rotation changed into and scan action.
In time meter embodiment, the action of scanning of pointer has the extremely accurately quality of timing of quartz system, and the thickness of meter can prevent to increase the time, or shortens the life-span of the battery of meter when being used to drive.
Therefore, meter when proposing a kind of simulation, mechanism that can be by will storing energy of rotation and steadily release storage energy control gear separate, with the stepwise operation at intermittence of timing circuit, what change pointer into scans demonstration continuously.
Therefore can see, in the purpose that becomes by front explanation clearly, the purpose that proposes above can reach effectively, simultaneously, owing to can do variation and not break away from the spirit and scope of the present invention to said structure, so top full content described and shown in the drawings all should be considered as the usefulness that narrates, and there is not the meaning of the restriction done.
It is also to be understood that the purpose of following claims, is to comprise the whole broad sense of the present invention and the characteristics of narrow sense, and whole statements of relevant invention with regard to language, should be thought between broad sense and narrow sense.
