Description

A Portable Power Generator [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable self-power generation apparatus that can easily carry and generate electric energy by self-generating smoothly outdoors, and more particularly, To a rotary self-generating device capable of stably obtaining electric energy in the open air without consuming any additional energy by converting the rotational energy into rotational energy and supplying the converted rotational energy through the small generator to generate electric energy.

As the society becomes more sophisticated, various electronic devices are being developed and its usage population is increasing day by day. In recent years, the use of portable electronic devices such as mobile phones is increasing.

And because of the development of outdoor leisure culture such as fishing, mountain climbing, etc., time for living outdoors is increasing.

In recent years, portable self-generating devices have been proposed and used in which electric energy consumed in various electronic devices used in living in the outdoors is acquired through self-power generation, and the necessary power is used in an emergency.

The conventional portable self-power generation apparatus has a disadvantage in that it is inconvenient to use and takes a long time because it has to implement a separate operation such as a predetermined operation (rotational movement of the lever) in order to generate electric energy.

Accordingly, self-power generation devices capable of easily generating electric energy have been proposed. One of them is Korean Patent Laid-Open No. 10-2007-91505 (name: portable self-generating device) The power generating device includes a plurality of magnet members which are formed in a round bar shape so that N poles and S poles are repetitively magnetized and are installed upright in the inside of the case as described in the publication, and a plurality of magnet members inserted in the outer periphery of the magnet member An elastic member provided on the case so as to repeatedly perform a lifting operation of the stator due to an inertial force connected to the stator and externally operated; and a stator having a stator and a magnet member A PC for designing a circuit for smoothing the power generation power output from the stator and forming it into a DC level B board, a rechargeable battery pack installed inside the case to receive and charge the voltage generated from the output terminal of the PCB substrate, and a power supply port for supplying the power charged in the rechargeable battery pack to the outside.

That is, the user is allowed to generate electric power through rocking (vibration) generated by walking or moving while the self-powered device is carried.

In Korean Patent Laid-Open Publication No. 10-2000-73212 (entitled "thermoelectric module external portable solar generator"), as described in the publication, a case; A thermoelectric module external lid rotatably coupled to one side of the case and having a thermoelectric module for solar heat collection and electrical energy conversion on its outer surface; A charging device provided inside the case for regulating and outputting the electricity generated by the thermoelectric module (solar cell thermoelectric module plate) to an appropriate state for charging the battery; An accumulator charged with a current output from the charging device; An indicator for indicating the charge level of the battery to the outside; An inverter for converting the direct current output from the battery into an alternating current according to need; Emergency generator; And an outlet for connecting a plug of an external electric appliance.

That is, it is intended to obtain electric energy by using solar energy which is natural energy.

However, such a conventional self-power generation apparatus has a problem in that power generation is not performed at night when solar heat can not be obtained, so that there is a time limitation.

On the other hand, in Korean Patent Registration No. 10-1512302 (name: portable self-generating device), as known in the art, there is a "tube" shape having a fluid passage having an inlet through which fluid flows and an outlet through which fluid is discharged A runner fixed on the fluid path of the body and adapted to generate rotational energy by receiving a fluid pressure of the fluid to be moved and to generate rotational energy; And a generator for converting the electric power generated by the generator into electric energy.

That is, the fluid is generated through the fluid flowing through the inside of the body to generate rotational energy.

However, such a conventional self-powered device has a problem that the space through which the fluid moves must be larger than the body.

That is, when the space in which the fluid is conveyed is irregular, it can not be used.

In addition, as disclosed in Korean Patent Registration No. 10-1621711 (titled "Hydraulic power generator combined with a hydraulic power unit using a compression energy type water bottle"), an aerator for spraying water and a water turbine And a power storage unit for storing the generated power. The hydrodynamic power generation apparatus includes a pumping port for applying pressure to the sprayer, a spray nozzle for spraying water in the sprayer, And a jetting operation port for jetting water into the jetting nozzle, wherein the aberration housing is formed, and the aberration housing has a " U " shaped aberration mount portion on which a ball bearing of an aberration axis on which the ball bearing is extruded is formed The aberration housing cap is covered with the aberration housing body and the aberration housing body with the injection nozzle insertion hole formed on one side thereof. Which has a hydraulic power generator is described.

In other words, the rotational energy is generated through the fluid discharged through the injection pressure.

However, such a power generation apparatus has a problem that efficiency of use is low because a separate injection device must be provided.
