Abstract

The utility model relates to a quartz clock with cursor display in electronic quartz clock system, which replaces the stepping motor, tooth gear and pointer system with cursors at different position of LEDs to indicate time. The utility model comprises three groups of LEDs, wherein, the hour group is composed of 12 LEDs respectively indicating the time from 1 o'clock to 12 o'clock; the 5-minute group is composed of 12 LEDs respectively indicating the time of 5 to 10 until 60 minutes; the 1, 2, 3, 4 and 5 minutes in each step of the 5 minute group are indicated through 5 diodes of the 1-minute group. The position of the 3 groups of LEDs is disclosed in the specification. The utility model has the advantages of beautiful appearance, novel design, simple structure, long service life, small energy consumption and low cost.

Description

The cursor quartz clock

At present, in the quartz clock, digital display type and pointer two classes are arranged.Digital display has liquid crystal different with light emitting diode again.The power consumption of making display of light emitting diode is big, uses alternating current, seldom adopts.Widely used is pointer crystal clock, quartz watch and liquid crystal quartz watch.There is following shortcoming in they, and pointer-type has stepper motor and transmission gear to produce wearing and tearing, and the life-span is not very long, and rotational noise is arranged, and cost is higher.The liquid crystal of liquid crystal type is a vitreum, and it and other circuit have tens electric terminals, and can not weld can only be gluing or press, and the contact loose contact often occurs, and numeral lacks stroke, and liquid crystal easily breaks in addition, and the life-span is very short.Last two kinds of clock and watch can't be seen when light is very dark and read.

Goal of the invention of the present utility model is to overcome above-mentioned shortcoming.Provide a kind of,, promptly replace pointer instruction time with luminous point also without the cursor quartz clock of motor, gear and pointer without liquid crystal.

Fig. 1 is that cursor quartz clock circuit diagram Fig. 2 is a cursor quartz clock structural drawing

Qualtz clock with cursor display of the present utility model comprises IC₁To IC₆, light emitting diode D and dial plate A form. It is characterized in that Fig. 1 IC finish the vibration frequency division counter release the code and output. IC wherein, vibration frequency division output sectors Be flushed to IC₂, by IC₂Output D behind the counting₁To D₆,IC ₂The I pin export 5 sectors and be flushed to IC₂The I pin, IC₃Be two tetrad counters, its 5 grouping outputs to IC₄,IC ₄Output to D₆To D₁₇,IC ₄14 pin output clock pulse be flushed to IC₃13 pin, IC₃A hour group output to IC₆,IC ₅Output D₁₈To D₂₉。T ₁,T ₂Be phase inverter, V₀Be power supply+4.5V. Light emitting diode divides 3 groups, such as Fig. 2, and D₁To D₅Be 1 grouping, D₆To D₁₇Be 5 groupings, D₁₈To D₂₉Be a hour group. The light emitting diode of 5 groupings and hour group is pressed in markers respectively On the corresponding points inside and outside the numeral. 1 grouping luminous tube is by on the summit of center five-pointed star. Diode operation glows, also But green glow, blue light or white light.

Its time is explicit to be step-by-step movement, and time group is one hour step, and in one 5 minutes steps of 5 groupings, 1 grouping is one minute step, stepping clockwise.5 groupings between per steps read in 1 grouping in 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes.As present 12 just, a D ₁, D ₆, D ₁₈Bright, 12: 1 D ₁D goes out ₂Bright, all the other are constant, and 12: 2, D ₂D goes out ₃Bright, all the other are constant ..., by 12: 5.D ₅D goes out ₁Bright, then circulation is next 5 minutes, simultaneously 5 grouping D ₆D goes out ₇Bright, D when all the other do not change to 10 minutes ₇D goes out ₈Bright or the like, by 60 minutes just, D ₁₇D goes out ₆Bright, 5 groupings begin new circulation again, simultaneously D ₁₈D goes out ₁₉Bright, this moment the time be 1 just.Connect down the circulation that begins next hour again.

The utility model is handsome in appearance, and modern design is simple in structure, accuracy of reading, and cost is low, power consumption is little, and the life-span is long.
