And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a perspective view of a portable self-generating device according to the present invention.

The portable self-power generation apparatus 10 (hereinafter referred to as a power generation apparatus) is composed of a body portion 20 having a cylindrical tumbler shape, and a fixed portion, such as a mobile phone, (Not shown). The fixing table 22 is further provided on the bottom surface of the charging pad 23, which makes it wirelessly chargeable, facing the mobile device.

The fixing table 22 does not necessarily need to be wirelessly charged. That is, a port for supplying electric power to the body 20 is provided, so that various mobile devices may be charged through connection of the port and the charging cable.

The fixing base 22 has a structure in contact with the mobile device and has a bottom surface for wirelessly charging and a fixing surface for fixing both sides of the mobile device on both sides of the bottom surface. The fixing surface is variable from the bottom surface so that it can be stably fixed to the fixing table 22 for charging regardless of the size of the mobile device.

The power generator 10 includes a drive shaft 30 across both ends. The drive shaft 30 is rotatably coupled to the take-up wheel 40 and the magnet 60, respectively.

When the user pulls the rope 42 provided in the power generation apparatus 10, the magnet 60 rotates together with the winding wheel 40 provided therein. At this time, the magnet 60 rotating by the operation of the wind-up wheel 40 reacts with the coil 64 provided in the body 20 to produce electricity, and the produced electricity is supplied to the body 20 And is charged with a battery (not shown). The operation principle according to the internal configuration of the power generation device 10 will be described in detail below.

A plurality of charging cables may be provided on the outer circumferential surface of the body portion 20 to connect the charging terminals with charging terminals having different shapes of various mobile devices. It is also possible that a USB port 24 or an outlet terminal is further provided.

2 is an internal perspective view of a portable self-generating device according to the present invention.

The inside of the power generation apparatus 10 is rotated by the body portion 20 provided with the drive shaft 30 and the rope 42 wound around the drive shaft 30 and the elastic body And a rewinding wheel 40 for rewinding the rope 42 while being reversely rotated by a worm wheel 40 (not shown). A coupling hole 61 for coupling with the driving shaft 30 is formed so that the magnet 60 is rotated together with the winding wheel 40 and the magnet 60 is disposed on the driving shaft 30 to reduce the rotation speed of the winding wheel 40, A reduction gear 50 for transmitting the rotation to the magnet 50 and a coil 64 provided toward the magnet 60 from one side of the body 20 are provided.

When the rope 42 of the winder 20 is suddenly pulled, not only the winder 20 but also the magnet 60 located on the drive shaft 30 rotate at a high speed. If the rotating force that rotates at a high speed is rotated without being decelerated, instantaneous high voltage electricity is generated. Accordingly, the electronic apparatus connected to the power generation apparatus 10 may be damaged by the high pressure, and there is a possibility that a problem may occur between the magnet 60 and the coil 64. [ Therefore, the reduction gear 50 is installed to prevent the rotation speed of the magnet 60 by adjusting the fast rotation speed of the rotation wheel 20. A plurality of reduction gears 50 are provided in a line in a direction parallel to the drive shaft 30. The plurality of reduction gears 50 are different from each other in gear ratio so that the rotation speed of the winding wheel 40 is sequentially decelerated, ) Is rotated at the slowest speed.

The reduction gear 50 is integrally formed with a body gear 52 positioned inside the body 10 and an internal gear 54 and a body gear 52 meshing with the inner peripheral surface of the body gear 52 And a shaft gear 56 for interpolating the drive shaft 30. At this time, one side of the body gear 52 is opened, so that the internal gear 54 located inside the body gear 52 may be detached from the body gear 52 when the internal gear 54 is rotated. Therefore, Is extended from the body portion 10 so that the internal gear 54 can stably rotate.

The pair of magnets 60 that engage with the connecting gear 57 of the reduction gear 50 are paired and the coils 64 are positioned between the two magnets 60. On the other hand, a pair of magnets 60 facing each other are connected in a plurality of axial connection portions 62 so that the magnets 60 can rotate together. At least one of the N poles and the S poles having different polarities is arranged on one surface of the magnet 60 facing each other. And the two facing magnets 60 are provided so as to face each other with a different polarity. As a result, the magnet 60 rotates between the coils 64, so that an electromotive force is generated between the magnet 60 and the coil 64, thereby producing electricity. That is, the magnet 60 has a pair of magnets 60 positioned with a coil 64 interposed therebetween, and a pair of magnets 60 facing each other are provided facing each other with different polarities. A plurality of polarities of the two magnets 60 are arranged so as to cross each other.

The coils 64 are formed as a pair and are installed from the inside of the body 10 to be positioned between the two magnets 60.

FIG. 3 shows a portable self-generating device according to the present invention in operation.

When the rope 42 provided on the body 20 is pulled, the winding wheel 40 is rotated together with the driving shaft 30, and both the reduction gear 50 and the magnet 60 are also rotated.

When the rope 42 connected to the elastic body is pulled out, the pulling wheel 20 is automatically pulled in. When the rope 42 is pulled in and pulled out, . However, when the rope 42 of the winding wheel 40 is reversed while being reversed, the reduction gear 50 and the magnet 60 must rotate in the original direction irrespective of this, so that the electric power can be stably supplied. The first eccentric bearing 70 is further provided in the hole of the winding wheel 40 that engages with the driving shaft 30. When the rope 42 is pulled, the driving shaft 30 rotates together with the winding wheel 40 do. However, when the rope 42 is wound and the wind-up wheel 40 makes a reverse rotation, the drive shaft 30 does not rotate backward along the wind-up wheel 40 by the first eccentric bearing 70, Direction.

As the drive shaft 30 rotates, the reduction gear 50 connected to the drive shaft 30 also rotates together. At this time, it is preferable that the reduction gear 50 provided on the drive shaft 30 is arranged in a row with a plurality of reduction gears 50 having different gear ratios in order to effectively reduce the rotation speed of the take-up wheel 40. The internal gear 54 fixed to the body gear 42 of the reduction gear 50 is fixed to the internal gear 54 so that the internal gear 54 is disengaged from the body gear 42, .

The plurality of reduction gears 50 is configured such that the first reduction gear 50a located at the upper end of the winding wheel 40 reduces the rotational speed primarily and the second reduction gear 50b located at the upper end thereof reduces the speed do. The third reduction gear 50c located at the uppermost one of the plurality of reduction gears 50 decelerates at the slowest speed so that the magnet 60 can be rotated at a speed much lower than the rotation speed of the winding wheel 40 . The number of reduction gears 50 is not necessarily limited to three as shown in the drawing and may be set to be more or less than the number of reduction gears 50. However, since rotation ratios of the plurality of reduction gears 50 are different from each other, The number of reduction gears 50 may be adjusted according to the rotation speed to be set.

The connecting gear 57 of the third reduction gear 50c is connected to the magnet 60 so that the magnet 60 can rotate at a constant speed irrespective of the rotation speed of the winding wheel 40. [ On the other hand, even if the second eccentric bearing 72 located in the coupling hole 61 of the magnet 60 directly engages with the shaft gear 56 to stop the reduction gear 50, the magnet 60 is rotated by the second eccentric bearing And is continuously rotated by the inertia of the rotor 72. Thus, as the magnet 60 continues to rotate, the user does not need to repeatedly pull the rope 42 to generate electricity, and only when the speed of rotation of the magnet 60 is low or stopped, The magnet 60 may be rotated.

Electricity will be generated as the pair of magnets 60 continue to rotate around the coil 64. The generated electricity may be charged to a capacitor or connected to an electronic device. This will be easy to use in a place such as a camping ground where the power supply is suddenly disconnected or where there is no electric facility.

Fig. 4 shows another embodiment of a portable self-generating device according to the present invention.

3, but there is a difference in the configuration of the drive shaft 30. [0064] As shown in Fig. The drive shaft 30 is connected to the first drive shaft 32 and the second drive shaft 34 in the same line and the first drive shaft 32 and the second drive shaft 34 are connected to each other by the protrusions 33 and the depressions 35 So that the insertion is made. The first eccentric bearing 70 is positioned on the outer circumferential surface of the protruding portion 33 so that the depressed portion 35 rotates only in one direction irrespective of the direction of rotation of the protruding portion 33. The shape of the projecting portion 33 and the depressed portion 35 may have the same shape as the cross projections and the cross grooves. In addition, any shape of the structure may be sufficient as long as the projecting portion 33 and the depressed portion 35 can be engaged with each other and pivotable together.

On the other hand, the first drive shaft 32 is provided with a winding wheel 40, so that the infeed and outflow ropes of the rope 42 are rotated. However, even if the rope 42 of the winding wheel 40 is rewound, only the first driving shaft 32 is reversely rotated by the first eccentric bearing 70 provided on the protruding portion 35, 34 are rotated in the original direction by the inertia of the first eccentric bearing 70. [

And a reduction gear 50 and a magnet 60 are provided on the second drive shaft.

A plurality of reduction gears 50 are arranged in a line along the second drive shaft 34 and a first reduction gear 50a located between the first drive shaft 32 and the second drive shaft 34 is positioned . That is, because of the first eccentric bearing 70 positioned between the first drive shaft 32 and the second drive shaft 34, the reduction gear 50 and the magnet 60 rotate only in one direction irrespective of the take- .

 A second reduction gear 50b located at the upper end of the first reduction gear 50a and a third reduction gear 50c at the upper end thereof. The connection of the reduction gear 50 is such that the shaft gear 56 of the first reduction gear 50a is in level engagement with the internal gear 54 of the second reduction gear 50b, And the reduction gears 56 are coupled to the internal gears 54 of the third reduction gear 50c so that the respective reduction gears 50 are different from each other in gear ratio so that the rotation speed of the winding wheel 40 is sequentially reduced. That is, the rotational speed of the first reduction gear 50a and the rotational speed of the magnet 60 coupled to the shaft gear 56 of the third reduction gear 50c are significantly different from each other. A detailed description of the internal configuration of the reduction gear 50 will be given later.

As described above, the reduction gear 50 does not necessarily have to be arranged in a line, but one reduction gear 50 may be used for adjusting the rotation speed of the magnet 60. It is also possible to use a greater number of reduction gears 50 than the reduction gear 50 used in this drawing.

The magnet 60 is engaged with the connecting gear 57 of the third reduction gear 50c to allow the reduction gear 50 to rotate the fast rotation speed of the winding wheel 40 at a reduced speed. Electricity will be generated as the magnet 60 continues to rotate around the coil 64 located between the pair of magnets 60. The electricity generated may be charged to a capacitor or connected to an electronic device.

5 is a detailed view of a reduction gear provided in the portable self-generated power generating device according to the present invention.

The reduction gear 50 serves to reduce the rapid rotation speed of the winding wheel 40 and adjust the magnet 60 installed on the second driving shaft 34 to rotate appropriately.

The reduction gear 50 is disposed between the winding wheel 40 and the magnet 60. The reduction gear 50 includes a body gear 52 having a protrusion formed inwardly and a plurality of teeth contacting the inner circumferential surface of the body gear 52 And a shaft gear 56 formed in a central portion of the body gear 52 and elongated in one direction along the drive shaft 30 so as to be in contact with both of the internal gears 54 and the plurality of internal gears 54, have. That is, as the body gear 52 and the internal gear 54 are coupled to each other to rotate the body gear 52, the plurality of internal gears 54 rotate together. At this time, (54) is lowered. The plurality of internal gears 54 and the shaft gears 56 are coupled to each other to be rotated. As a result, the shaft gears 56 rotate at a lower rotation ratio than the body gears 52.

A shaft gear 56 having a long length along the drive shaft 30 and a magnet 60 having a coupling hole 61 are coupled to rotate at a suitable speed to produce electricity. The rotation ratio may be adjusted by adjusting the number of gears of the body gear 52, the internal gear 54 and the shaft gear 56 so that the magnets 60 and the coils 64 are adjusted to the most suitable ratio to produce electricity.

The use of the reduction gear 50 makes it possible to simplify the gear structure inside the power generation apparatus 10 and simplify the structure of the power generation apparatus 10 to make the size of the power generation apparatus 10 compact . Therefore, the portability can be improved and the electric power can be efficiently produced.

6 is an exploded view of an eccentric bearing provided in a portable self-generated power generating device according to the present invention.

The eccentric bearings 70 and 72 are arranged such that the ball 79 is engaged with the magnet 60 so as to be rotatable together and rotates together with a coil 64 positioned between the rotating magnet 60 and the magnet 60, So that electricity can be generated. Therefore, the ball 79 needs to be able to maintain the rotation state for a predetermined time even if the magnet 60 rotates in one direction so as to produce electricity of a constant voltage and does not receive the turning force from the wind-up wheel 40.

The inner structure of the ball 79 that enables rotation only in one direction is located inside the outer wheel 78 and the outer wheel 78 that rotate between the magnets 60, An inner wheel 76 which is directly coupled to the drive shaft 34 and a sprag 57 located between the outer wheel 78 and the inner wheel 76 for allowing the ball 79 to rotate in one direction .

Therefore, even if the inner wheel 74 directly coupled with the first drive shaft 32 or the second drive shaft 34 rotates together, the rotation of the inner wheel 74 79 and the sprags 57 to restrain the outer wheel 78 from rotating in the reverse direction. When the ball 79 rotates once, the outer wheel 78 continues to rotate due to the inertia of the ball 79 even if the second drive shaft 34 and the inner wheel 74 stop. In other words, the second eccentric bearing 72 may use a one-way clutch bearing that transmits power to rotate in one direction and continuously rotates by inertia.

The balls 79 and the sprags 78 will not necessarily need to use only the shapes shown in this figure and the eccentric bearings 70 and 72 will continue to move even if the first drive shaft 32 or the second drive shaft 34 is stopped Any eccentric bearing 70 (72) may be sufficient as long as it is a gear having a structure capable of rotating in one direction. Furthermore, a ratchet gear may be used.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
