JPH11164539A - Small-sized flat generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a generator as a substitute for a battery for a portable electric apparatus, e.g. the electric circuit of a portable telephone. SOLUTION: A spiral spring 4 is wound up by rotating a manual rotor 1b, and through this output torque the magneto rotors 8, 9 of a single-phase DC generator are rotated. An output generated in the armature coil of a stationary armature 10 by the rotation of the magnet rotor 8, 9 is converted into a DC output, and this Dc output is used as the power source for the electric circuit of a portable electrical apparatus.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is used as a power source for small portable electric devices such as pagers.

2. Description of the Related Art Although a generator using a magnet rotor is well known, there is no small-sized flat device for generating power by manual force which has been put to practical use.

[0003]

The driving energy is stored in the mainspring by manual torque, thereby driving the generator to generate power for a required time and operating the pager for the required time by the generated energy.
An object of the present invention is to provide a means for making a call even when the battery is not stored or when the stored battery is exhausted. It is another object of the present invention to provide a means that does not require expensive charging equipment for charging the battery.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to FIG. The same reference numerals in the drawings denote the same members, and a duplicate description will be omitted. FIG. 1 is a diagram showing the appearance. FIG. 2 is a sectional view. 1 and 2, a disk-shaped manual rotator 1b is supported on the side surface of the outer casing 1 via a rotary shaft 3 so as to be freely rotatable therearound. The rotating shaft 3 is rotatably supported on the side surface 1a of the outer casing 1 by a bearing (not shown), and a gear 6 is fixed to the right end thereof. The manual rotor 1b and a later-described ratchet gear 2 are fixed so as to rotate synchronously.

The one shown by the dotted line 4 is a spiral spring.
The central end is fixed to the rotating shaft 3, and the outer peripheral end is fixed inside the outer periphery of the ratchet gear 2. On the outer periphery of the ratchet gear 2, ratchet teeth 2a are provided as shown in FIG.
The left end of the lever 11 is engaged, and the right end thereof is rotatably supported by a support shaft 11a provided on the main body, and is repelled in the direction of arrow B by a spring (not shown). Therefore, when the ratchet gear 2 is manually rotated in the direction of arrow A, the mainspring 4 of FIG. 2 is wound up and drives the gear 6 via the rotating shaft 3.

Gear 6 in FIG. 2 Small gear 7 meshing with this
a, a large gear 7 and a small gear 8a meshing with the large gear 7,
To increase speed. An annular magnet rotor 9 is fixed inside the outer periphery of the rotor 8, and a fixed armature 10 whose magnetic pole faces the magnetic pole via a gap is fixed to the side plate 1a.

FIG. 4 is an exploded view. A fixed armature having magnetic poles 9a, 9b,... Arranged at the same pitch inside the magnet rotor 9 and having magnetic pole widths equal to the N and S magnetic pole widths and separated by the magnetic pole widths. 10 are provided, and each magnetic pole has an armature coil 12.
a, 12b,... are mounted. Manual rotor 1 of FIG.
When b rotates, the magnet rotor 9 is driven at a higher speed via the mainspring 4 as described above, so that power is generated in the armature coils 12a, 12b,. When this power generation output is used for a pager, the required output is about 5 volts and 100 milliamps.

FIG. 4 is a developed view of the magnet rotor 9 and the armature coils 12a, 12b,..., And only one part is shown because of the large number of magnetic poles. A power generation output can be obtained from the terminals 13a and 13b. The device of the present invention has the following features because it is an abduction type magnet rotor. First, the relative speed between the N and S magnetic poles and the magnetic poles 9a, 9b,. Second, even in a single-phase generator, the power generation frequency is high, so the size of the smoothing capacitor is small. When a small storage battery is stored and charged for use, no capacitor is required. Third, since a large number of armature coils are connected in series, the output voltage increases.

In FIG. 5, the output of the generator 14 is converted into a DC output by a rectifier circuit 15 including a diode, and the output is used as a power source for an electric circuit 16 of the mobile phone. Means of using a battery as a power source has a disadvantage that the battery is dead and cannot be used. However, according to the means of the present invention, there is an effect that this disadvantage is eliminated. Of course, when used in combination with a battery, the battery can be charged automatically.

[0011]

【Example】

If the drawing of FIG. 2 is made as an actual size, an output voltage of 5 volts and 80 milliamps can be obtained, and when the mainspring is wound up, a required output of about 30 seconds can be continuously obtained.

[0012]

When the present invention is applied to a portable telephone, it is possible to prevent a problem that a conversation cannot be performed due to a drain of a battery. Further, there is an advantage that an expensive charging device is not required. Since it can be configured to be small and flat, it can be used as a power source for other electrical appliances that require the above-described effects.
