Description

Portable self generator

The present invention relates to a portable self-generator, and in particular, the present invention relates to gears in which a plurality of generators are integrally coupled to a main gear that rotates about an axis connected to a handle, and the plurality of generators as the main gear rotates. To generate electricity to charge the battery and to be charged to the battery using an external solar panel or direct power supply, which can be used for emergency activities or leisure activities such as night hiking, camping or fishing. It relates to a portable self-generator.

Conventional small generators are made by miniaturizing large generators and their structure is the same as large ones. That is, it is made of a stator and a rotor in a cylindrical shape.

It uses a magnet power generation method that generates permanent magnets arranged in a cylindrical shape on the outside and used as a field magnet and rotates the armature located in the center.

This method has a cylindrical structure with a large surface area of the magnet and armature, which is not suitable for miniaturization.

In addition, miniaturization of the cylinder makes it extremely difficult to increase the polarization of the armature, making it difficult to increase power generation efficiency.

Therefore, in order to solve the above problems, Korean Patent Publication No. 1999-0073236 portable generator has been developed.

The portable generator consists of a rotor and a stator.

That is, the disk is rotated by a rotating shaft installed perpendicularly to one side, at least two magnets formed in the circumference of the disk in the direction in which the rotating shaft is attached, and the bearing coupled to the rotating shaft of the disk at the center, the magnet And a stator having at least two armature cores formed on a surface corresponding to the stator, a coil made of wire wound around the armature core of the stator, and a case for fixing the stator and protecting the disk from outside.

The rotating shaft of the disk is coupled to the rotational force generating means consisting of a plurality of gears for rotational amplification by hand force, and the organic electromotive force generated in the coil is rectified in the rectifier circuit on the printed circuit board to produce the battery as the power required of the portable device It is stored in or supplied to an auxiliary power source in case of emergency.

In addition, domestic utility model registration No. 20-0140329 portable manual generator has been developed, as shown in FIG.

This relates to a hand-operated generator that can be used for emergency use when the battery is completely exhausted in the open air, and more particularly to a hand-held hand-held generator developed for military use in the field. Conventionally, in case of emergency such as exhibition, if the supply of supplies is not smooth or the stored battery is completely consumed, the operation of the operation is severely impaired. Therefore, a portable generator that does not consume electric energy even when left for a long time is required.

Briefly describing the configuration, the lower portion of the casing 11, the lower portion of the casing portion 10, the bracket 12 is mounted on the lower side of the casing 11, and the upper end of the handle 21 is arranged in the casing 11, the lever ( Acceleration part 30 is composed of a handle portion 20, the intermediate gear 32 and the driven gear 33 meshed with the main gear 31 of the rotary shaft 31a of the handle 21, the 24 is arranged. And a power generation unit 40 including a rotor 41 and a stator 42 arranged on the driving shaft 33a, and a connector unit 50 including an outlet 51 connected to the power generation unit 40. By configuring the power supply, the power supply can be stably supplied to various electronic devices through the outlet 51 connected to the power generation unit 40 by simply rotating the handle 21 even when the emergency storage battery is not supplied in an emergency such as an exhibition. It is to be able to perform the mission effectively, by the lever 24 and the elastically adjustable handle 21 is easily folded Ease is to be enhanced.

However, in the former case, there is a limit in power generation capacity, while the latter case can be used temporarily. There was a problem that it is difficult to use for a long time.
