Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a clock-driving device combined with a conventional core and in particular, to clock-driving device combined with a conventional core that takes advantage of the oscillation mode of a traditional quartz oscillator, wherein, a magnet is provided on its hand and, as the magnet enters the sensing region of a reed sensor, a periodic sensing path can be generated and triggers the startup of a motor to drive a micro-motive device, and a rotational mandrel to output; as the action finished, the micro-motive device will disconnect the path to save electrical power.

2. Description of the Prior Art

The ingredient of quartz is silicon dioxide (SiO2). When quartz is placed in an oscillating circuit and under a specific condition, it can transfer its own frequency into the circuit. A traditional core device takes advantage of this specific feature of quartz and converts electric energy into kinetic energy via a quartz oscillator. The circuit board is typically mass-produced using a mechanized equipment, which, after incorporated in resistors and capacitors, becomes a finished product. Since quartz oscillator core has been used in practice for several tens years, its production techniques is well established and besides, its price is quite low. In addition, conventional quartz oscillator has several advantages including accuracy, low weight and easiness for maintenance.

Since driving structures used in a conventional digital clock comprises of employing a coil motor to drive said device, in order to achieve automatic changes of minute, hour, date, month, week, and year, the structure needs always a number of mechanical control parts for engagement and control. Under these circumstance, in case of using common batteries to power the structure, too much electric power might be consumed to result in frequent replacement of batteries and hence cause inconvenience in life and waste of resources. Furthermore, because the coil motor used in the structure of a conventional digital clock must produce horse power for generating clock, driving coil, and activating minute sheet, hour sheet, date sheet, month sheet, week sheet and year sheet, events such as insufficient electric power might occur frequently and thus could incur poor performance of that digital clock as well as too much consumption of electric power.

In addition, if a large size hanger clock or wall clock or digital clock is required in response to a special requirement, the conventional fabrication way comprises scale up the whole clockworks, from motor to running gears, in accordance with an appropriate proportion. These would result in not only material- and time-consuming, but also increasing of price at higher proportional as well as inconvenience for future maintenance.

Thus, it can be seen that the above-described conventional articles have still many disadvantages, and not of a perfect design, which need improvement at once.

In view of the above-mentioned disadvantage associated with the conventional structure, the inventor had thought to solve and improve by combining with the structure of a conventional quartz oscillator core, and, finally, after studying extensively for many years, developed successfully the clock-driving device combined with a conventional core.

SUMMARY OF THE INVENTION

Accordingly, one object of the invention is to provide a clock-driving device combined with a conventional core, characterized in that it is a core device of conventional quartz oscillating mode and hence renders the invention to have advantages as low cost and stable frequency.

Another object of the invention is to provide a clock-driving device combined with a conventional core, characterized in that a reed sensor is provided on the hand of a conventional core structure, and, thereby the reed sensor can sense the periodic motion of the hand to trigger the motor periodically such that the electric power can be saved accordingly.

Yet another object of the invention is to provide a clock-driving device combined with a conventional core, characterized in that is can calculate the clock by means of the conventional core structure and that the motor for the output rotation mandrel uses a separate energy source to save the electric power.

The clock-driving device combined with a conventional core that can achieve the above-mentioned objects is consisted of a conventional core device, a magnet, a reed sensing device, a driving motor, a micro-motive device, an output rotational mandrel and two set of batteries, wherein said magnet is provided on a hand of said conventional core device, and said reed sensing device is embedded at an appropriate position such that as the magnet moves associated with the periodical motion of said hand and enters the sensing region of said reed sensing device, a sensing path can be generated periodically, which in turn triggers the motor, and at the same time, interrupts the circuit by means of said micro-motive device such that the rotational output can be adjusted and controlled stably and efficiently into a constant clock as well as can save the electric power.

The clock-driving device combined with a conventional core provided by the invention has following advantages:

• 1. A property of stable frequency from conventional core device by providing a magnet on the hand of the conventional core to trigger stably a reed sensing device and driving the motor.
• 2. By interrupting the sensing path with a micro-motive device to save electric power and achieve the effect of extending the service life of the battery.
• 3. Since the motor is triggered to drive before acting without being kept always at a ready state, the service life of the clockworks can be extended.
• 4. Since the power supply used in the invention can be divided to each respective motor provided for driving sheets of minute, hour, day, month, year and the like, respectively, for drive large size sheets or large size hands of a wall clock, it can be done by just replacing the motor and power supply thereof.
• 5. The invention can use a single power supply and hence simplify the equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to better understand the structure, use and characteristics of the invention, the invention will be described in detailed with reference to two non-limiting example in conjunction with accompanying drawings as follows.

Referring to FIG. 1, a schematic view illustrating the layout of the clock-driving device combined with a conventional core according to the invention, comprises a conventional core device 1 with its own power supply 11 separated from the power supply 10 associated with a motor 7 loop; a small magnet 5 provided on the second hand 4 of the conventional core device 1 and moving in combination with the second hand 4, that is, under this situation, the speed of the magnet 5 being 1 round per minute; reed sensing devices 2 and 3 provided diagonally with each other in the moving path of the magnet 5 such that, as the magnet 5 enters the sensing region of the reed sensing device 2 or 3, it will be sensed and an electric communication is thus generated to trigger the operation of the motor 7, i.e., 2 electric path generated per minute to trigger the operation of the motor 7, while during rest time, the motor 7 loop is interrupted so as to save electric power; and a micro-motive device 6 for controlling and examining the whole loop such that the 2 paths per minute is converted to a constant radian per minute and that the motor 7 is operated correspondingly to drive a output rotational mandrel 8 and the associated flipping of pure digital sheets 9, wherein said sheet 9 can display minute, hour, date, month and year, as minute and hour displayed in FIG. 1. The output rotational mandrel 8 accomplishes one action per minute and flips once the sheet of the unit place minute. For every ten time the unit place minute sheet flipped, the tens place minute sheet will be brought to flip once and for every six times the tens place minute sheet flipped, the unit place hour sheet will be brought to flip once and the forth. These can be coupled with the conventional core device 1 and displays accurate time synchronously.

Now referring to FIG. 2, the loop of the motor 7 is illustrated schematically therein. The reed sensing device 2 is connected in series to the normally closed terminal NC of the micro-motive device 6 and is connected in parallel to the reed sensing device 3 that is connected in turn in series to the normally opened terminal NO of the micro-motive device 6. Whereas the reed sensing device 3 that is connected in series to the normally opened terminal NO of the micro-motive device 6 is connected in series to a common terminal COM of the micro-motive device 6. Thus, as the magnet 5 enters the sensing region of the reed sensing device 2, said reed sensing device 2 will sense it and generates a communication path to trigger the motor 7. The motor 7, in addition to rotate the output rotational mandrel 8, engages also the gear 62 of the micro-motive device 6. The gear 62 of the micro-motive device 6 will then bring the switching of the micro-motive device 6 to its normally opened terminal NO to interrupt the original communication path. The next communication path of the motor 7 will be generated from the sensing of the reed sensing device 3 that is connected in series to the normally closed terminal NO of the micro-motive device 6 and will be interrupted upon the switching of the micro-motive device 6 to its normally opened terminal NO, and this cycle will be repeated so on.

Referring to FIG. 3, a schematic view illustrates the operation of the micro-motive device 6. The motor 7 drives the rotation of the gear 62. A protuberance 62 is provided at a suitable position on the gear 62. When the gear 62 rotates, the protuberance 63 will drive a teeterboard member 64 which, by pressing down the button 65 of a micro-switch 61, can in turn switch over the normally opened terminal NO and normally closed terminal NC of the micro-motive device 6.

Referring to FIG. 4, showing another embodiment of the invention, the reed sensing device 3 is removed and the reed-sensing device 2 is connected in series to the normally opened terminal NO of the micro-motive device 6 with an additional circuit.

Referring to FIG. 5, a schematic view illustrates this embodiment corresponding to the above description. The clock output from sensing of both is shown and compared in FIG. 6. FIG. 6a shows the clock output from the sensing of another embodiment of the invention. FIG. 6b shows the output clock from the sensing of this embodiment.

Similarly, the battery 11 of the conventional core 1 can be removed and the electric power is supplied instead from the battery 10 to achieve the purpose of simplification.

Referring to FIG. 7, a schematic view illustrates the layout of the clock-driving device combined with a conventional core according to the invention.
