However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention may further degenerate other inventions or the present invention by adding, changing, or deleting other elements within the scope of the same idea. Other embodiments that fall within the scope of the inventive concept may be easily proposed, but they will also be included within the scope of the inventive concept.

In addition, the components with the same functions within the scope of the same idea shown in the drawings of each embodiment will be described using the same reference numerals.

1 and 2 are views for explaining an example in which the power generating device according to an embodiment of the present invention is applied to a bicycle, Figures 3 and 4 are provided in the power generating device according to an embodiment of the present invention It is a figure for demonstrating a rotating arm, a rope wheel, and a drive wheel.

1 to 4, the power generator 10 according to an embodiment of the present invention may be applied to a moving means that moves by rotating a wheel by a driver's power or a motor, for example, as shown in the figure. It can be applied to a bicycle that is moved by the force of the pedal as the driver presses.

However, the power generator 10 according to the present invention is not necessarily applied only to a bicycle that is moved by the force of the pedals of the driver, and may be applied to any means for rotating and moving the wheel which is the driving wheel by the rotational movement.

Hereinafter, the power generating device 10 according to the present invention will be described by way of example applied to the bicycle moved by the force of the pedal pedal.

The power generator 10 may be located on both sides of the pedal in a manner using a rope rather than a conventional chain, but for convenience of description, only the one side is described, and the other side may be located. Note that the same can be applied.

The power generator 10 is a rope 100, the rope drum 200 is connected to the rotating shaft of the first wheel 12, which is the rear wheel of the bicycle while the rope 100 is wound, the forward direction by the rotation of the pedal ( Rotation arm 300 and the rotation wheel in the reverse direction (R2) may be implemented repeatedly and the rope wheel 400 mounted on the inner side of the rotary arm 300.

The rope 100 may be a plastic material made by twisting numerous filaments of a material having a high density, for example, a polyamide fiber such as widely used in sailing sailing, the diameter is about 2 to 4mm, and high It can have strength and low elasticity.

The rope drum 200 is connected to the first rotating shaft A1, which is the rotating shaft of the first wheel 12, is rotated in the forward direction R1 by the unwinding of the wound rope 100 and the first wheel ( 12) may be a component that rotates in the forward direction R1.

The rope drum 200 may be formed in a cylindrical shape, the outer surface may be formed with a guide groove for winding the rope 100 in the correct position.

A spring, for example, a spiral spring may be disposed inside the rope drum 200, and the spiral spring ensures that the rope 100 is wound around the rope drum 200.

When the rope 100 is pulled forward while the rope 100 is wound on the rope drum 200, the rope 100 wound on the rope drum 200 is unwound and at the same time The rope drum 200 is also rotated in the forward direction (R1).

When the rope drum 200 is rotated in the forward direction (R1), the first wheel 12 is also rotated in the forward direction (R1) by the first rotating shaft (A1) connected to the rope drum 200, the bicycle Go forward.

Here, when the rope drum 200 is rotated in the forward direction (R1), the spiral spring located therein is elastically deformed, the rope drum 200 is reversed by the restoring force by the elastic deformation of the spiral spring ( The force to rotate to R2) is applied.

The rope 100 is unwound from the rope drum 200 by the rotation of the rotary arm 300 and then rewound by the rope drum 200. By repeating this operation, the first wheel 12 is The bicycle is advanced by rotating in the forward direction R1.

Here, the spiral spring disposed inside the rope drum 200 to rotate the rope drum 200 in the reverse direction (R2) by a restoring force, through which the rope 100 to the rope drum 200 It can be wound up.

When the rope drum 200 is rotated in the reverse direction R2, unlike the rotation in the forward direction R1, the rope drum 200 has no influence on the rotation of the first wheel 12, which is different from the rope drum 200. The configuration located at the center of the first wheel 12 that is interlocked and rotated is interlocked with the first wheel 12 when rotating in the forward direction R1, but the first wheel when rotating in the reverse direction R2. Because it is independent of (12).

This is because a component called a freewheel, which is a structure that transmits power only in one direction, is located at the center of the first wheel 12 and the component is connected to interlock with the rope drum 200.

The rotary arm 300 is rotated in the forward direction R1 and the reverse direction R2 with respect to the second rotation axis A2 within a predetermined angle range by the rotation of the pedal mounted on the frame of the bicycle. It may be a component repeatedly implemented.

The rotary arm 300 is a head arm 310 connected to the second rotation axis (A2), the driving wheel 500 extending forward from the head arm 310 and rotated in conjunction with the rotation of the pedal (500) Drive arm 320 to provide a drive path of 322, the rope wheel 400 is mounted to the inside of the rotary arm 300 and by the rotation of the drive wheel 500 to the rope 100 It may include a traction arm 330 for providing a traction force and a connection arm 340 for connecting the driving arm 320 and the traction arm 330 to ensure robustness and load support.

The rotary arm 300 may be manufactured in the form of a single plate, but may be implemented by fastening the stainless steel plates of the same shape at a predetermined distance from each other for strength and cost reduction.

Here, the separation distance between the stainless steel plate is enough that the drive wheel 500 is inserted so that the drive wheel 500 can be stably moved in the interspace.

The driving wheel 500 is a component that rotates in conjunction with the pedal by the rotation of the pedal, it may perform a function of transmitting the rotational force of the pedal to the rotary arm (300).

When the pedal rotates, the driving wheel 500 is inserted into the driving path 322 of the driving arm 320 formed as a groove or a hole to move along the driving path 322, and the driving wheel 500. The rotation arm 300 is rotated in the forward direction R1 and in the reverse direction R2 within this predetermined rotation.

Here, the driving path 322 does not necessarily need to be formed as a groove or a hole, and may be implemented in a structure such that the driving arm 320 is inserted into the driving wheel 500.

Meanwhile, the rope wheel 400 unwinds the rope 100 wound on the rope drum 200 when the rotary arm 300 is rotated in the forward direction R1 by the rotation of the pedal. The rope 100 may be mounted inside the rotary arm 300 while the rope 100 is connected.

The rope wheel 400 is advanced when the rotary arm 300 is rotated in the forward direction (R1), to unwind the rope 100 wound on the rope drum 200, the rotary arm 300 is When rotated in the reverse direction (R2), it can be retracted so that the wound rope 100 is wound on the rope drum 200.

Here, the principle in which the rope 100 is wound on the rope drum 200 is due to a spiral spring located inside the rope drum 200, and an operation principle thereof is as described above.

The rope wheel 400 may be inserted into and fixed to the mounting groove 332 formed at the end of the traction arm 330, and the rope wheel 400 may be the rope 100 of the rope wheel 400. It may be inserted into the mounting groove 332 while connected to. This will be described later with reference to FIGS. 9 to 12.

After the rope 100 is wound around the rope wheel 400, it is finally wound on the balance wheel 600 is fixed to the frame.

In other words, the rope 100 has one end and the other end fixed to the rope wheel 400 while the middle portion of the entire length is bent, and then removes the balance wheel 600 from the frame, and removes the balance wheel 600. The bent portion is wound on the balance wheel 600 while being mounted to the frame.

Thereafter, the rope 100 between the balance wheel 600 and the rope wheel 400 is connected to the rope wheel 400, that is, after winding, the rope wheel 400 is connected to the rope 100. Inserting into the mounting groove 332 formed at the end of the traction arm 330 by using an external force is the connection of the rope 100 is completed.

On the other hand, the power generator 10 according to the present invention may be located on both sides of the pedal, respectively, the rope wheel 400 of the power generator 10 located on one side of the pedal by the rotation of the pedal is advanced to the first When the first wheel 12 is moved forward, the rope wheel of the power generating device located on the other side of the pedal is reversed, and the bicycle can realize a smooth running without interruption of power by the mutual interaction as described above.

5 to 8 are diagrams for explaining the principle of moving the bicycle to which the power generator according to an embodiment of the present invention is moved.

5 to 8, when the driver applies a force to the pedal, the pedal is rotated, and the driving wheel 500 is rotated in association with the pedal. In this process, the driving wheel 500 is the driving arm 320. It is moved along the driving path 322 of, the rotary arm 300 is to be rotated in the forward direction (R1) within a predetermined angle range.

When the rotary arm 300 is rotated in the forward direction (R1), the rope wheel 400 is advanced downward slightly due to the rotation relative to the second axis of rotation (A2) of the rotary arm 300, In the process, the rope 100 wound on the rope drum 200 is unwound, and the rope drum 200 is rotated in the forward direction R1 to rotate the first wheel 12 in the forward direction R1.

When the first wheel 12 is rotated in the forward direction R1, the bicycle moves forward.

When the pedal continuously rotates in the state as shown in FIG. 7, the pedal proceeds to the same state as shown in FIG. 5 after passing through the state as shown in FIG. Will be rotated.

When the rotary arm 300 is rotated in the reverse direction (R2), the rope wheel 400 is retracted so that the rope 100 is wound on the rope drum 200, wherein the rope drum 200 is reverse Rotate to (R2), but the first wheel 12 has no effect due to the freewheel.

By repeating the above series of operations, the bicycle can be driven.

On the other hand, when the process proceeds to the state as shown in FIG. 5 in the state as shown in FIG. 8, the driving wheel 500 may be finely deviated from the drive path 322 of the drive arm 320, The departure prevention arm 350 can effectively solve this problem.

When the driving wheel 500 reciprocates the driving path 322 by the repetitive rotation of a pedal, the departure preventing arm 350 may be separated from the driving path 322. To be prevented, it may be a component extending in a predetermined length toward the rear, which means a direction from the head arm 310 toward the traction arm 330.

When the driving wheel 500 is finely separated from the driving path 322, the departure preventing arm 350 may cover the driving wheel 500 in a separation direction to prevent separation, and the driving Like the path 322, the driving wheel 500 may be inserted into a groove or a hole.

On the other hand, the departure prevention arm 350 has been described using a separate term from the head arm 310, this is for convenience of description, the head arm 310 is formed extending from the head arm 310 It may be a component of).
