Abstract

The utility model relates to a pointer-digit dual display clock, comprising a pointer-type display, a digital display, etc. The pointer-digit dual display clock can simultaneously use pointers and digits to display time, time can be synchronously displayed through the two display methods without correction, and the two display methods can be mutually complemented. The pointer-digit dual display clock has novel style and clear display; the pointer-digit dual display clock can be used in family, and when made into a large-sized clock, the pointer-digit dual display clock can be used for the public places, such as the airport, the station, the wharf, the square, the sports hall, etc.; the pointer-digit dual display clock can be made into children toys or teaching aids to help the children learn the time of the clock by being properly simplified.

Description

Pointer-digit dual display clock or watch

Traditional clock and watch are pointer, watch the position of pointer just can know the time, and needn't remove careful reading, and can also know that according to the position of pointer how long poor the schedule time (for example arriving on schedule) is also, but children begin to learn difficulty comparatively of indicated time of understanding clock and watch pointer.The electronic watch reading that modern digital shows is directly perceived, demonstration is accurate, but lacks whole time showing, and it is also how much poor to desire to know from the present time to the schedule time, must calculate after some deliberation.

The purpose of this utility model provides a kind of pointer, the two clock and watch that show of numeral, and it can use pointer and digital demonstration time simultaneously, and these two kinds of display modes are made up for each other's deficiencies and learn from each other.

Its scheme is:

For analog timepiece, set up the digital display panel of branch and the time digital display dial, with suitable gear drive, make branch, the time digital display dial rotation corresponding with the rotation of branch, hour hands, thereby in the display window of clock face, demonstrate time of pointer indication with numeral.

For the digital display type electronic watch, set up temporal information translation circuit and simulated pointer display, with temporal information in the clock and watch be transformed into second of time figure display synchronization, branch, the time signal, drive the track that the simulated pointer display simulates goes out the pointer operation.

Accompanying drawing has been described two embodiment of the present utility model.

Fig. 1 is the embodiment of pointer clock and watch additional character display.

Divide digital display panel 1 by its tooth 2 and back gear 3 engagements, simultaneously, back gear 3 and minute wheel 4 engagements.The number of teeth of axle tooth 2 is identical with the number of teeth of minute wheel 4, so they are with the equidirectional rotation of speed.So,, divide digital display panel 1 just to show with the numeral minute numerical value that the minute hand (not shown) on the minute wheel 4 is indicated by the display window of clock face 5.

Divide digital display panel 1 with the time digital display dial 6 diameter identical, the ten two/part in its garden week has tooth, these teeth can with the time digital display dial 6 teeth of garden on week be meshed.Dividing digital display panel 1 whenever to turn around is one hour.It whenever turns around, and digital display dial 6 rotates 1/12nd circle when just stirring, and changes hour display digit (time have on the display panel 6 1～12 totally ten two-digits).

Obviously, numeral shows that the time of indicating with pointer is consistent all the time.

This example only increases the two-digit display panel on existing clock and watch basis, simple in structure, easily manufactured.

This two clock and watch that show are simplified, are removed parts such as the energy and transmission, keep index system and display panel, then can make toy for children or teaching aid, make children in recreation by display window apparent numerology can be familiar with the indicated time of clock and watch pointer.

Fig. 2 is the embodiment of the additional simulation of digital display type electronic watch pointer display device.

12 hours digital display type electronic watch electrical schematic diagrams processed in Fig. 2 frame of broken lines. This example is drawn respectively the BCD code of temporal information from each counter output, obtain by each BCD/ decimal decoder 1 show when synchronous with time figure, a minute, second position and ten output signals of minute, second (also can draw temporal information from each digital display input, decipher obtaining above-mentioned output signal through field/decimal system). For Shi Shiwei, because only needing 0,1 two number, needn't dedicated decoders, only with a not gate 2, ten output signals in the time of just can obtaining. Above-mentioned each output signal by each and door 3 decodings, is just obtained 0～59 second, 0～59 minute, 0～11 o'clock each output signal.

For the motion of analog timepiece pointer, line up a circle with 60 displays, represent respectively 0～59 second, they show under the driving of 0～59 second output signal in turn, form the track that second hand moves.

Because the speed of minute hand and second runner is obviously different, in order to reduce the quantity of display, reduce cost, above-mentioned 60 displays also can represent the track of minute hand operation simultaneously. For this reason, with 0 second and 0 minute, 1 second and 1 minute ... 59 seconds and 59 fens output signals are respectively by each or door 4, obtain 0 second or 0 minute, 1 second or 1 minute ... amounted to 60 output lines, and be connected respectively to (5 can comprise drive circuit) on each display 5 in 59 seconds or 59 minutes.

If divide not and share display second, then remove each or door 4, line up a circle with 60 displays in addition and do to divide and show, be connected respectively on each display 5 with 3 from each.

For the time demonstration, then use 12 displays, second with divide the display circle with the interior circle of lining up, represent respectively 12 hours.

Aforementioned display device can be light emitting diode, incandescent lamp, neon light, liquid crystal display etc.

Obviously, the time of the time of numeral demonstration and simulated pointer indication is consistent all the time.

This two demonstration clock and watch have a fashion style, show clear, except individual and family's use, if make large-scale clock and watch, can use for public places such as airport, station, harbour, square, gymnasium.

Claims

1, a kind of two mechanical clocks that show that constitute by pointer display and digital display device, digital display dial when it is characterized in that having branch numeral display panel and one, the digital display panel of described branch is identical with minute wheel by a number of teeth, and ten two/part of the axle tooth and the circumference that are meshed with back gear has tooth, and with the time tooth on the digital display dial circumference disk that is meshed constitute; The time digital display dial by a diameter with divide digital display panel identical, and have the disk of tooth to constitute on the circumference.
