Description

The mechanical drive clock and watch that electric light shows

The utility model relates to a kind of Mechanical Driven or electrically driven (operated) clock and watch, specifically a kind of clock and watch that can show the hour at the dark place.

Existing all kinds of mechanical clocks, crystal clock or the electroclock tables etc. that use have included dial plate, pointer, watch module and driving mechanism.For easy recognize time, generally all be with the bigger color differentiating of contrast pointer, hour number and dial plate.In order to improve the visibility at the dark place, also mostly is to adopt the outer light source irradiation or the fluorescent material of coating to wait to realize.Use outer light source irradiation, its power consumption is bigger, uses uneconomical.Its visibility of fluorescent material of coating also only very close, slightly far then recognizes unclear.And fluorescent material itself also has certain harm to human body, should not be extensive use of.

The purpose of this utility model just provides a kind of clock and watch of knowing recognize time and using economy, to overcome the deficiency of existing clock and watch, satisfies daily life and need of work.

The utility model is achieved in that clock and watch still include several parts such as dial plate, pointer, watch module and driving mechanism, on each the hour position of dial plate and pointer light emitting diode is set, in order to the demonstration time.Because dial plate is a fixed sturcture, the light emitting diode on it directly connects power supply after the parallel connection, and pointer need be set up a cover arrangements of electric connection because of being movable rotary part, switches on the light emitting diode on pointer.This arrangements of electric connection is on the final stage gear in the gear train of watch module two copper sheet slip rings to be set, and is connected in the lasso of pointer by axle sleeve both sides lead-in wire, at pointer internal lead sending and receiving light pipe.Set up a brush dish on final stage gear top, the face of trying to get to the heart of a matter is provided with two brushes and contacts with two slip rings respectively.Brush is located by securing member, and communicates with power supply.Luminotron on dial plate and the pointer is lighted, reached clear at a distance, recognize time exactly.Because light emitting diode power consumption is few, therefore use economy, and the brightness of light emitting diode is higher, daytime, night are all very eye-catching, identify very clear.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the final stage running part structural representation in the watch module in the utility model.

Fig. 2 is that the A-A of Fig. 1 is to view.

Fig. 3 is that the B-B of Fig. 1 is to cut-open view.

Fig. 4, Fig. 5 are the circuit diagrams of two kinds of power supply modes.

Though the driving mechanism and the watch module of various clock and watch are different, final stage running part and dial plate, pointer etc. all are identical, promptly as shown in Figure 1, and socket minute gear 11 on the minute hand axle sleeve 4, socket hour hand gear 10 on the hour hands axle sleeve 9 of minute hand axle sleeve outside.At minute hand axle sleeve 4 end socket minute hands 8, at hour hands axle sleeve 9 end socket hour hands 7.If second hand is arranged on the clock and watch, then in the minute hand axle sleeve, be installed with second hand axle, axle two ends tap second hand and second hand wheel.The utility model is that minute gear 11 and hour hand gear 10 end faces in the gear train of watch module are pasted two concentric slip rings respectively, and the center of circle and the gear center of circle coincide.Post two axial copper sheet leads respectively on the both sides of minute hand axle sleeve 4 and hour hands axle sleeve 9.Two copper sheets 5 on the minute hand axle sleeve 4 keep respectively being electrically connected with two slip rings on the minute gear 11, and promptly copper sheet top is affixed on the gear bottom surface earlier, pass gear again and slip ring joins.Two copper sheets 6 on the hour hands axle sleeve 9 keep respectively being electrically connected with two slip rings on the hour hand gear, and connected mode is the same.Be with

brush dish

1,3, two brush dishes on minute hand axle sleeve 4 in gear train and the hour hands axle sleeve 9 respectively and lay respectively at the top of minute gear 11 and hour hand gear 10.The front end that is pasted with 2,12, two groups of brushes of two brushes at the two brushes face of trying to get to the heart of a matter respectively contacts with two slip rings of two gears, 10,11 end faces respectively, and the afterbody of two groups of brushes is fixed on the location-plate by securing member, and the positive and negative electrode of tap power supply.Location-plate can be fixed parts such as watch module cover plate.As shown in Figure 2, brush can be made the shift fork shape, has a hook solid to turn up in the two ends of shift fork.This structure both can make each shift fork that two contact points are arranged, and can make hook solid turn up the formation Elastic Contact again, thereby had realized reliable electrical connection.Among Fig. 3, the lasso inboard of the minute hand 8 in pointer is pasted with two contact copper sheets, passes the middle part of pointer with two leads 13 that two copper sheets link to each other respectively, is electrically connected with the light emitting diode 14 of needle tip installation.Concrete method for making can be that minute hand is made with two stickups, before pasting earlier with wire bonds at light emitting diode and contact on the copper sheet, repaved lead, with two involutory, paste into pointer, at last fixedly luminotron with contact copper sheet.The structure of hour hands 7 and minute hand identical, lasso slightly larger in diameter only is to match with hour hands axle sleeve 9.Like this, brush 2 is connect positive source, brush 12 contact power cathodes, copper sheet lead 5 by two slip rings and minute hand axle sleeve both sides, make electric power transfer to sleeve end, contact copper sheet on minute hand 8 and lead 13 converge on the light emitting diode at last again, constitute electric loop, the luminotron on the minute hand is lighted.Luminotron on the hour hands is in like manner also lighted.

A light emitting diode all is equipped with in each hour position at dial plate.Each luminotron parallel connection (shown in Fig. 4,5) is connected to both ends of power behind the series resistor R2 again.These clock and watch power supply can adopt 220 volts of AC power, is serially connected with resistance R 1 and commutation diode D1 on the one output terminal.If the use dry cell, then these clock and watch power supply is 3 volts of direct currents, is serially connected with resistance R 1 on the one output terminal.Resistance R 1, R2 are divider resistance, with the protection light emitting diode.

This clock-type is by installing the luminotron display device additional, visibility can reach hundred meters, clearly identification has with the naked eye overcome the defective that existing clock and watch in the dark or at a distance are difficult for identification, can use as the time set in various places such as family, indoor, hotel, station.And the shape of luminotron, color can with the clock and watch matching design, make clock and watch on the basis of clocking capability, increased decorative effect again, sight strengthens.
