Abstract

PROBLEM TO BE SOLVED: To provide a portable electric apparatus, such as a generator used in place of a cell of a mobile phone electric circuit.SOLUTION: The present invention comprises: a device that winding up a spiral spring by turning a manual rotor to drive the rotation of a magnet rotor of a single-phase DC generator by its output torque; a device that converts a generated output developed in an armature coil of a stationary armature by the rotation of the magnet rotor into a DC output; and a device that uses the DC output as a power supply of an electric circuit in a portable electric apparatus.

Description

Used as a power source for small portable electric devices such as pagers.

A generator using a magnet rotor is well known, but there is no small flat device that generates power by manual force.

The drive energy is stored in the mainspring by manual torque, and the generator is driven to generate power for the required time, and the pager is operated only for the required time by this generated energy. It is to provide a means for making a call even when exhausted. Another object of the present invention is to provide a means for eliminating the need for expensive charging equipment for charging the battery.

A manual rotor that is rotatably supported by a support shaft on the side surface of the outer casing and a part of the outer periphery of the outer casing protrudes from the side surface of the outer casing, and the mainspring housed inside by rotating the manual rotor manually. A device for winding and holding, a speed increasing gear for increasing the drive speed of the mainspring and rotating a flat and annular magnet rotor housed in the outer casing, and magnetizing the inner peripheral surface of the magnet rotor A fixed armature having a plurality of annular N and S magnetic poles, a magnetic protrusion that faces the inner peripheral surface of the N and S magnetic poles through a gap and is spaced apart by the width of the magnetic pole, and the fixed armature The armature coil is connected to the armature coil, and the power generation output of the armature coil is connected in series to rectify the power generation output to obtain a single-phase power generation output.

When used for a mobile phone, it is possible to prevent the inconvenience of being unable to interact due to battery exhaustion. Moreover, there is an advantage that an expensive charging device can be omitted. 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.

External view of the device of the present invention Sectional view of the device of the present invention Explanatory drawing of operation of manual rotor Development view of fixed armature and magnet rotor Block diagram of overall configuration

The details of the present invention will be described with reference to FIG. Since the same symbols in the drawings are the same members, redundant description is omitted. FIG. 1 is a diagram showing the appearance. FIG. 2 is a cross-sectional view. 1 and 2, a disk-shaped manual rotor 1 b is supported on the side surface of the outer casing 1 through a rotating shaft 3 so as to freely rotate around the rotating shaft 3. 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 lathe gear 2 are fixed so as to rotate synchronously.

What is indicated by a dotted line 4 is a spiral spring, the central end is fixed to the rotary shaft 3, and the outer peripheral end is fixed to the inner periphery of the ratchet gear 2. As shown in FIG. 3, a ratchet tooth 2a is provided on the outer periphery of the ratchet gear 2, 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. Is repelled in the direction of arrow B. Therefore, when the ratchet gear 2 is manually rotated in the direction of arrow A, the mainspring 4 in FIG. 2 is wound up, and the gear 6 is driven via the rotary shaft 3.

The gear 6, the small gear 7a meshing with the gear 6, the large gear 7 and the small gear 8a meshing with the gear 6 in FIG. An annular magnet rotor 9 is fixed inside the outer periphery of the rotor 8, and a fixed armature 10 that is opposed to the magnetic pole via a gap is fixed to the side plate 1 a.

FIG. 4 is a development view. Inside the magnet rotor 9, the magnetic pole widths 9a, 9b,. . . Are provided at equal pitches, and each magnetic pole has armature coils 12a, 12b,. . . Is installed. When the manual rotor 1b of FIG. 2 is rotated, the magnet rotor 9 is driven at an increased speed via the mainspring 4 as described above, so that the armature coils 12a, 12b,. . . Generates power. When this power generation output is used for a pager, the required output is about 5 volts and 100 milliamperes.

4 shows a magnet rotor 9 and armature coils 12a, 12b,. . . In this development view, only one part is shown because the number of magnetic poles is large. A power generation output can be obtained from the terminals 13a and 13b. Since the device of the present invention is an abduction type magnet rotor, it has the following characteristics. First, the N and S magnetic poles and the magnetic poles 9a, 9b,. . . The relative speed is large and the generated voltage is large. Secondly, since the power generation frequency is large even in the single-phase generator, the smoothing capacitor is small. When a small storage battery is housed and charged for use, a capacitor is not necessary. Thirdly, since many armature coils are connected in series, the output voltage increases.

In FIG. 5, the output of the generator 14 described above 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 a mobile phone. The means for using a battery as a power source has the disadvantage that the battery becomes unusable due to the rise of the battery, but according to the means of the present invention, there is an effect of eliminating this drawback. Naturally, when used in combination with a battery, the battery can be charged automatically.

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