Abstract

PURPOSE:To make the life of an electronic timepiece semipermanent by providing a power generation mechanism inside the timepiece to eliminate troublesomeness in the exchange of batteries. CONSTITUTION:A stator 21 is so arranged as to surround a rotor 20 including a permanent magnet 20a, a coil 22 is wound on a magnetic core 22a and the magnetic core 22a and the stator 21 are fastened with a screw 23. As the rotor 20 runs, an electromotive force is generated in the coil 22 to develop a current. The use of an unbalance wheel as rotating means can realize an automatic photo-quartz timepiece. A rotary motion generated by the unbalance wheel causes a rotor magnet 20a to turn with a speed increasing wheel train. As a power is induced in the coil 22 as shown by the fine line 45 with a rectification circuit, current flows as shown by the fine line 45 and accumulated into a capacitor 5. Or as a power as shown by the broken line 46 is induced in the coil 22, current flows as shown by the broken line and accumulated into the capacitor 5. This eliminates the need for any battery to make the life of an electronic timepiece semipermanent.

According to this embodiment described above, an automatic optical crystal watch is realized because an unbalanced wheel is used as the rotating means. Regarding the power generation mechanism, the coil movable unit type shown in Japanese Patent Application Laid-Open No. 50-17866 has a limit in increasing the size of the coil because the coil is rotated, and the power generation efficiency cannot be increased. Also, the brush part is a mechanical contact point, so there is always concern about the mother. Also, in terms of size, it has to be thick in order to obtain the number of turns of the coil. In addition, it is difficult to process thin cylinders with magnets, and it is difficult to use strong magnets such as rare earth magnets that have been put into practical use in recent years.This also has the disadvantage of not being able to increase power generation efficiency. For example, it is possible to arrange the magnets and coils, which are the components of the generator, in a layout separated from each other, and it is possible to set them according to the required characteristics.

コイルもコイル回転型のユニット型に比しきわめて大き

The coil can also be made much larger than that of a rotating coil unit type, and the power generation efficiency can be increased. Furthermore, the magnet is of a thick-walled cylindrical shape and is extremely easy to process, and all kinds of magnets such as rare earth magnets can be used.

Also, since the magnetic flux of the magnet is taken out by constructing an output circuit using high magnetic permeability materials such as the stator and the magnetic core, the magnetic flux N interlinks with the coil.

φ is extremely large. Therefore, from this aspect as well, the power generation efficiency is greatly increased.

Furthermore, since each element can be arranged in a distributed manner, other components, such as the gear train and circuits, can be freely arranged in consideration of the overall layout of the watch, and its space efficiency is extremely high.

Further, in this embodiment, a large capacity capacitor is used as the power storage means. A capacitor is not a chemical reaction like a battery, but a physical phenomenon, and the lifespan of the power storage device itself is extremely long.With the system implemented in this study, a lifespan similar to that of a conventional spring-type watch can be obtained, and of course, there is no need to replace the battery. It is possible to create clocks with high precision, such as crystal clocks, without the appearance of a quartz clock.

もちろん本発明は本実施例に限るものではない。Of course, the present invention is not limited to this embodiment.

回転手段について、本実施例はアンバランス車の回転運

Regarding the rotation means, although this embodiment utilizes the rotation motion of an unbalanced wheel, the present invention is not limited to this.

For example, the rotor of the generator may be rotated by rotating an external operating member such as a winding stem, or both methods may be used in combination.

As a combined method, there is also a method of using a rotation means using an unbalanced wheel in the first stage of the winding stem, and driving the speed-increasing gear train by the rotation of the winding stem when the winding stem is pulled out one stage; The rotation of the winding stem is transmitted to the speed-increasing gear train through the rocking wheel using a mechanism so that the rotation of the unbalanced wheel is not transmitted to the winding stem, so that the winding stem does not act as a brake on the rotation of the unbalanced wheel. It is also possible to configure it as follows.

又アンバランス車のアンバランス部は第3図においては
増速輪列や発電器等とほぼ同一断面に配置されており薄

In addition, the unbalanced portion of the unbalanced vehicle is arranged in almost the same cross section as the speed increasing gear train, generator, etc. in FIG. 3, and the effect of making the vehicle thinner is significant.

Moreover, this unbalanced portion 31b is not limited to this structure, and other structures are of course possible.

For example, in the present embodiment, a large-capacity capacitor is used for the power storage means 5, which can easily increase the unbalance amount by placing it on the receiver 33 in FIG. 3, but any rechargeable power source can be used. But it doesn't matter. For example, rechargeable lithium batteries, solid electrolyte batteries, and the like have recently been put into practical use, and these batteries themselves have a large capacity and long-term reliability, and are suitable power sources for the present invention. Silver batteries can also be used as a means of storing electricity, although there are some problems with their long-term reliability.

Further, although the configuration from the control circuit after the power storage means to the pointer which is the display means in FIG. 1 is shown as an example of a hand display, the display means may be a digital display such as an LCD instead of a hand.

As described above, according to the present invention, by having a power generating mechanism inside the watch, it is very effective in eliminating the trouble of replacing batteries, which is the biggest drawback of electronic watches, and making the life of the watch semi-permanent. It is.

In addition, as a generator configuration, the coil and magnet are separated, and they are magnetically connected by a stator, and the coil is fixed.
By rotating a magnet to generate AC power, the number of turns in the coil and the number of magnetic flux passing through the coil, which have the greatest effect on power generation efficiency, can be extremely large, making it possible to obtain large power generation in a small space, and for the first time in a watch size. This made it possible to create a practical power generation system.

Furthermore, as in the present invention, the magnet, stator, and coil are completely independent components that can be assembled at the same time when the watch is finally assembled, thereby greatly improving ease of assembly and repair. Also, in terms of space, it is possible to arrange the watch using the gaps of various other components, and it is possible to prevent the watch from becoming larger and thicker due to the introduction of the power generation system. Moreover, this configuration is a non-contact converter, and the long-term reliability of the contact portion and other parts is also high.
