Description

DETAILED DESCRIPTION OF THE INVENTION The present invention converts the mechanical energy of a rotary weight, which rotates due to rocking when carried, into electrical energy through various transmission mechanisms, and uses it as a power source for, for example, an electronic wristwatch. This invention relates to a portable power generation device that can generate power.

Portable electronic devices, such as electronic watches, generally use primary batteries such as silver batteries or mercury batteries as power sources, so the electromotive force gradually decreases as energy is consumed.
After a certain period of use, the battery must be replaced with a new one.
Users were inevitably disadvantaged and inconvenienced.

In view of the above-mentioned points, the present invention can be incorporated into a portable electronic device, and is capable of supplying electrical energy to a secondary battery housed inside an electronic wristwatch, for example, and constantly charging it. It is an attempt to provide a portable power generation device that can maintain a desired energy capacity.

Embodiments of the present invention will be described below based on the drawings. In FIG. 1, 1 is a rotating weight, and this rotating weight 1 is rotatably supported via a bearing 2 such as a ball bearing.

The rotary weight 1 is constructed in the same manner as the rotary weight of a self-winding wristwatch, and swings and rotates in an arbitrary rotational direction as shown by arrow A depending on a change in posture. 3 is a rotation conversion mechanism that converts the rotation of the rotary weight 1 into rotation in only one direction, and this rotation conversion mechanism 3 includes an eccentric pin 4 provided on the rotary weight 1;
A magic lever 5 supported by the eccentric pin 4 and reciprocated as the rotating weight 1 rotates; a transmission wheel 6 rotated in only one direction by the magic lever 5; It is composed of an intermediate wheel 7 that meshes with each other.

The intermediate wheel 7 of the rotation conversion mechanism 3 drives a gun wheel 8 as an energy storage wheel. Escape wheel 8 is intermediate wheel 7
A shaft portion 10 having a pinion 9 that meshes with the pinion 9, and an escape tooth 11a.
, 11b, 11c, and this rotating wheel 1.
It consists of an intermittent rotation transmission wheel 13 that is provided on the top surface of 2 and rotates integrally with the rotating wheel 12.
It is connected to the shaft portion 10 via (FIGS. 1 and 2). The spring 14 functions as an energy storage member that stores rotational energy. The escape wheel 8 is controlled to rotate intermittently by the control device 15 to accumulate energy.
A release takes place. The control device 15 controls the angle stem 1 by a cam 16 having a pinion that meshes with the intermediate wheel 7, and by this cam 16 and the escape teeth 11a, 11b, 11c.
The angle 18 is a control member that swings about 7 as a center axis of rotation. The angle 18 has a pair of claws 19, 20 that engage with the escape teeth 11a, 11b, 11c. One claw 19 is formed short, and the other claw 20 is formed long. The intermittent rotation of the escape wheel 8 is transmitted to the rotor wheel 21 by the intermittent rotation transmission wheel 13.

The rotor wheel 21 meshes with the intermittent rotation transmission wheel 13 and is supported by the shaft portion 22. A rotor 23 made of a magnet or other magnetic material is fixed to this shaft portion 22. However, the rotor 23 is configured to rotate coaxially and integrally with the rotor wheel 21. A stator 24 wound with a coil is provided opposite to the rotor 23, and the stator 24 is connected to a rectifier 27 via lead wires 25, 26. ,3
1 to the secondary battery 32. As the secondary battery 32, for example, a silver battery, a nickel-cadmium alkaline storage battery, or the like is used. 33 and 34 are output terminals and lead wire 35
, 36 to the electrode terminals 30, 31 (
Figure 2).

A step motor can be used as the mechanism consisting of the rotor wheel 21, rotor 23, and stator 24. Using a battery that also has the function of a primary battery, such as a silver battery, as the secondary battery 32 can bring about a particularly great effect in terms of ensuring the operation of the device and extending the usable time of the battery. can. In the portable power generating device configured in this way, the rotating weight 1 rotates arbitrarily in the direction of arrow A by swinging when carried, and the rotation of the rotating weight 1 is controlled in one direction via the rotation conversion mechanism 3. (arrows F, G) and is transmitted to the escape wheel 8.

The shaft portion 10 of the escape wheel 8 is rotated in the direction of arrow B via a pinion 9 that meshes with the intermediate wheel 7. At this time, the rotating wheel 12
Since the escape teeth 11a are in contact with the claws 20 of the angle 18, the rotating wheel 12 (and the intermittent rotation transmission wheel 13) is maintained in a stopped state even when the shaft portion 10 rotates. Therefore, the spring 1 that connects the shaft portion 10 and the rotating wheel 12 is
4 is elastically deformed as the shaft portion 10 rotates and is strongly pulled in the rotational direction, so that the spring 14 can store the rotational energy of the rotating weight 1. The rotation of the intermediate wheel 7 causes the cam 16 to rotate in the direction of arrow C, and at this time the angle 18 is pushed downward in FIG.
It rotates in the direction of arrow D1 about the central axis.

By rotating this angle 18, the claw 20 becomes the escape tooth 1.
Since the spring 14 is separated from 1a and the contact state is released, the spring 14 tries to restore its original state vigorously by the force accumulated through its elastic deformation, and the accumulated energy is released instantaneously. The rotating wheel 12 connected to the spring 14 rotates vigorously in the direction of arrow B. As the rotary wheel 12 rotates, the intermittent rotation transmission wheel 13 also integrally rotates in the same direction as the rotary wheel 12 (arrow B direction), causing the rotor wheel 21 meshing therewith to rotate in the arrow E direction. As the rotor wheel 21 rotates, the rotor 23 integrally rotates in the same direction (arrow E direction), and as the rotor 23 rotates, current flows through the coil of the stator 24, generating an electromotive force. As the rotating wheel 12 rotates, the escape teeth 11b come into contact with the claws 19.

However, since the claw 19 is formed short, it does not stop the rotation of the escape tooth 11b, and the escape tooth 11
The claw 19 is pushed downward by the rotational force of b, and as a result, the angle 18 rotates in the direction of arrow D2. Therefore, the angle 18 returns to its old position, and the escape tooth 11
b comes into a stopped state when it comes into contact with the claw 20 (the claw 20 is long and exerts a stopping action on the escape tooth).
When the cam 16 pushes the angle 18 again, the above operation is repeated and an electromotive force is generated in the stator 24 each time. Since the rotational energy of the rotary weight is stored in the energy storage wheel up to a certain value and then released to rotate the rotor, the electromotive force generated also exceeds a certain value.

If this electromotive force is set to be larger than the value required for charging, the generated electromotive force is rectified by the rectifier 27 and applied to the secondary battery 32, and charging is performed. Since the present invention is constructed as described above, for example, when the present invention is incorporated into an electronic wristwatch and used, the rotary weight 1 rotates countless times each time the user moves his arm, and this rotational energy is transferred to the energy storage wheel. Therefore, the energy is accumulated up to a certain value, and the accumulated energy is intermittently transmitted to the rotor wheel 21 to rotate the rotor 23 vigorously, generating an electromotive force that can sufficiently charge the stator 24, and the generated electromotive force is Electric power can be applied to the secondary battery 32 to charge it, so that the electronic wristwatch can be continuously powered at a desired energy state. Normally, the amount of rotation of rotating weight 1 is
However, according to the present invention, since an energy storage wheel is used, the amount of rotation (rotation angle) is insufficient to generate sufficient electromotive force to charge the battery. By storing rotational energy, sufficient electromotive force can be generated to charge the battery. According to the present invention, unlike conventional electronic wristwatches, there is no need to particularly reduce power consumption and replace the battery every 1 to 2 years, and one battery can be used for an extremely long period of time. This eliminates unnecessary financial burden on the user, and there is no risk of inconveniences such as malfunctions, time delays, or stoppages due to battery consumption. Furthermore, in the present invention, the rotor 23 is rotated by the rotor wheel 21 that transmits the intermittent rotation of the energy storage vehicle, and the rotation of the rotor 23 generates an electromotive force, so that the energy can be transmitted smoothly. In addition to this, the electromotive force generated is also large.

The present invention is not limited to the above embodiments, and various improvements and modifications are possible.

For example, the step motor parts consisting of the rotor wheel, rotor, and stator that make up the movement converter for wristwatches can be used as they are in the power generation device of the present invention, so the cost is low, and the step motor manufacturing Since the technology has been established, mass production is easy, and it is extremely advantageous in terms of manufacturing. Also, the number of teeth (or diameter) of the rotor wheel
is less than the number of teeth (or diameter) of the intermittent rotation transmission wheel (
(or smaller), or by installing an appropriate gear etc. between the rotor wheel and the intermittent rotation transmission wheel, and making the motion transmission system from the intermittent rotation transmission wheel to the rotor wheel a speed-increasing wheel train system.
Power generation and charging efficiency can be increased. Furthermore, the above-mentioned motion transmission system does not necessarily need to be based on gears. For example, it can also be rotated using Masatsu resistance. The portable power generator according to the present invention can be used not only for electronic wristwatches, but also for portable wireless transceivers, electronic desktop calculators, etc.
Can be attached to and used in various portable electronic devices,
Its uses are great.
