Description

The motor machine clock and watch

To the utility model relates to the motor be power, go up a kind of clock and watch structure of bar automatically for mechanical clock.

The last bar mechanism of standard machinery clock and watch is by being installed in the click wheel on the bar axle and by table the little steel wheel of, clock key actuated rotation being formed, drives upward bar of bar axle rotation by the engagement of large and small steel wheel.The artificial bar of regularly going up has a lot of inconveniences.Think the last bar mechanism of the mechanical type automatic watch that addresses this problem design, by be installed in autoplugger on the bar axle, wheel is formed automatically, is installed on the movement skeleton by clamping plate, by carrier's activity, orders about upward bar of autoplugger swing.This weak point that goes up the bar mode is that it has increased autoplugger and clamping plate double-layer structure than general wristwatch, make the watchcase thickening, and autoplugger is heavier, ceaselessly swings the wearing and tearing of axle bigger, if leave standstill one to two day with out of service, it does not solve substantive issue.Chinese patent CN92210364.X in wrist-watch, designed a kind of with the motor be power go up voluntarily bar automatically on bar mechanism, this mechanism is made up of the recloser of battery, miniature cocurrent electromotor and a control motor break-make running, recloser wherein is that the contact by clockwork spring that is communicated in battery the two poles of the earth in barrel respectively and barrel inwall constitutes, utilize the degree of tightness limit and the contact of clockwork spring to close from realizing on-off circuit, gear drive by bar axle and motor shaft passes to clockwork spring with the motor rotating torque, bar in the realization.There is big defective in this bar mechanism of going up, contacts moment when clockwork spring is relaxed to the contact, circuit turn-on, motor rotation, but clockwork spring is screwed just immediately and the contact dialysis slightly, motor is in moment work, and clockwork spring does not really screw, and begins the work of new round break-make when walking slightly again.Series circuit short time break-make repeatedly in the practical application produces the electric shock spark again and again, final this device of scaling loss, and the frequent fortune of motor is stopped, and has shortened serviceable life.Therefore should design not satisfactory.

Goal of the invention of the present utility model is to provide a kind of machinery kind table that can go up bar automatically, and a kind of high motor machine clock and watch of bar efficient of going up are provided or rather.

Technical solution of the present utility model is, the replacement of bar mechanism is gone up by electronic by the last bar mechanism of existing clock and watch, it is provided the energy, power is provided, is communicated in the clockwork spring at battery the two poles of the earth and recloser that the contact on the barrel is formed respectively and constitutes jointly by motor by battery, the driving wheel on barrel that is fixed on the barrel directly meshes in second wheel, and its major technique is characterised in that the place, contact is provided with permanent magnet or the magnetite with magnetic force absorption clockwork spring.

In the technical program, different with the different structure of contact according to the setting of permanent magnet.Contact structure is that an end is fixed on the reed on the barrel, the contact of the unsettled conduct of its other end and clockwork spring break-make, and permanent magnet is fixed on this contact, but the metal level that its surface plating one deck conducts electricity very well; The another kind of structure of contact is the arc reed that two ends are fixed on the barrel inwall in this programme, and permanent magnet is fixed on the barrel inwall of arc reed under arc; In order to increase the stroke of clockwork spring, in this programme, the contact is a block permanent magnet that is fixed on the barrel inwall, and its coating surface has the metal level that conducts electricity very well.

The motor machine clock and watch that the utility model provides, abandoned the drive mechanism of centre wheel and third wheel, make the direct and second wheel engaged transmission of driving wheel on barrel, having reduced running resistance provides advantage for using the electronic bar mechanism of going up automatically, has dwindled the clock and watch size greatly from two aspects.With the motor is that power realizes going up automatically the bar function, because of being provided with permanent magnet or magnetite at the contact place, just can be when clockwork spring be relaxed to contact nature contact position under the effect at magnetic force with the contact adhesive, lead the energy circuit, can under the drive of clockwork spring para-electric machine, be tightened onto again in the time of can offsetting magneticaction and with the contact dialysis, prolonged the duration of runs of motor, clockwork spring is screwed by firm, overcome the drawback that a large amount of losses of components and parts in the former design are difficult to really go up bar again, not only eliminated connecing of producing between contact and the clockwork spring, the cutoff flower, and make motor finish the once bar task that goes up really, prolong its serviceable life.

Describe the utility model in detail below in conjunction with the following drawings:

Fig. 1 is the utility model structural representation

Fig. 2, Fig. 3, Fig. 4 are three kinds of example structure figure of recloser of the present utility model.

The utility model is based on standard machinery clock and watch structure, it is manually gone up bar structure change and be the electronic bar mechanism of going up, and except that last mechanism, watchcase, dial plate, indicator, movement are identical with the existing machinery clock and watch basically.This electronic bar mechanism of going up is connected by the battery 1, DC micromotor and the recloser that are provided with in the movement to constitute mutually.Recloser is to be made of the contact 10 on clockwork spring 7 that is connected to battery 1 the two poles of the earth and barrel 4 inwalls, and transmits rotating torque by motor steel wheel Z1 on the motor shaft and the engagement of the barrel steel wheel Z2 on the bar axle, is bar on the clockwork spring 7.In the present embodiment, adopted the driving wheel on barrel Z3 that is fixedly connected on the barrel 4, directly with movement in the structure that meshes of second wheel Z4, this structure has not only been saved two in the existing movement and has been taken turns, and has walked shortcut, reduced running resistance, increase thrust, improved performance when walking especially can reduce clockwork spring concerning clock elastic index requirement, used short and thin clockwork spring can reach its timing standard, save material, reduce cost, and dwindled barrel size in the clock and watch.

In the present embodiment, clockwork spring 7 is fixed with barrel 4 electrical isolations, and bar colludes stud 8 and adopts insulating material.Contact 10 is for being fixed on the reed 16 on the barrel inwall, and its free end is fixed with a permanent magnet or magnetite 11, and its surface is coated with one deck electric conductivity good metal layer.

Another example structure of contact 10 is that two ends are fixed on the arc reed 15 on barrel 4 inwalls, fixes a permanent magnet or magnetite 11 on barrel 4 inwalls under arc.

The third of contact 10 implemented structure and is in the utility model, forms by being fixed on the permanent magnet on barrel 4 inwalls or the layer of metal layer of magnetite 11 and surface plating thereof.
