BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a contact charging electric generator, and more particularly, to a contact charging electric power generator in which a metal layer is deposited on a polymer substrate and then the metal layer and the polymer layer are electrically charged However, unlike the conventional sliding-mode contact-type power generator, the polymer and metal layer are realized as a three-dimensional laminate structure in the form of rolls, so that the contact area between the polymer layer and the metal layer is effectively widened with a small volume, And a method of manufacturing the sliding contact charging electric generator.

In general, the development of the contact charging system is based on the generation of electrostatic charges that occur upon contact between two materials. The potential difference between the electrodes connected to the material is caused by the electrostatic charge which is induced by the positive charge on one side and the negative charge on the other side when the two materials are brought into contact with each other. Repeated electrical signals can be obtained by repeating the above-mentioned electric induction phenomenon.

In the case of the contact charging generator using the basic contact and separation as described above, two materials far from the charging column are used in order to obtain a sufficient output. In general, one of the electrodes is a polymer to which the electrode is connected and the other is a metal material . In this case, the metal material is positively charged at the time of contact and separation, and the polymer material is negatively charged, thereby generating a potential difference between the two electrodes.

On the other hand, there is a sliding-mode contact-charging power generator in which, besides the contact charging generator using the simple contact and separation phenomenon described above, another material is repeatedly sliding on one surface to generate contact charging.

Since the above-mentioned contact charging generator applies an electrostatic charge induction phenomenon, a large effective contact area at the time of contact is advantageous for the output. Accordingly, in order to obtain a sufficient output, various techniques for broadening the effective area by inserting micro or nano-sized fine structures on the surface of a polymer or a metal are generally being developed.

At this time, in the fabrication of the microstructure described above, an abacus having a microcube or a pyramid pattern is formed using a basic silicon etching, a polymer layer having a microstructure is formed by soft lithography, or a nano- There is a technique of making a polymer layer having a size structure.

However, in the conventional contact charging electric generator as described above, there is a limit in the contact area between the two materials for generating contact charging, and there is a limit in realizing a contact charging electric generator with high output.

Hereinafter, the operation principle of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

1 is a perspective view of a high output sliding contact charging electric generator using a roll shape according to an embodiment of the present invention.

1, the high-output sliding contact charging electric generator using the roll shape of the present invention includes an outer cylinder 100, an inner cylinder 110, magnets 120a and 120b of an outer cylinder, magnets 120c and 120c of an inner cylinder, 120d, a substrate 130, a metal layer 140, and the like.

The inner cylinder 110 is a cylinder for producing a roll shape of the substrate 130 charged by sliding in the contact charging electric generator. The inner cylinder 110 is formed as a cylindrical shape in FIG. 1, but is not limited thereto. The inner cylinder 110 may be made of PMMA and may be disposed opposite to the magnets 120a and 120b provided on both sides of the outer cylinder 100 in order to make the roll- The magnets 120c and 120d may be installed. These magnets 120c and 120d may be configured so that the same electrodes as the corresponding magnets 120a and 120b of the outer cylinder 100 facing each other are disposed.

The outer cylinder 100 is a cylinder configured to surround and enclose an inner cylinder 110 having a roll-shaped substrate 130 formed therein. Like the inner cylinder 110, the outer cylinder 100 is formed as a cylinder in FIG. 1, But is not limited thereto. The outer cylinder 100 can be made of PMMA like the inner cylinder 110 and the magnets 120a and 120b for restoring the inner cylinder 110 can be attached to both ends of the outer cylinder 100 . That is, for example, when the inner cylinder 110 is positioned inside the outer cylinder 100 and the roll-shaped substrate 130 is slid in the lateral direction from the inner side of the outer cylinder 100, A magnetic repulsive force is generated between the magnets 120a and 120b attached to the inner cylinder 110 and the magnets 120c and 120d attached to the inner cylinder 110 so that the inner cylinder 110 is positioned at the center portion on the outer cylinder 100 .

The substrate 130 is an element for generating contact charging through a sliding operation in the contact charging electric generator, for example, a polymer substrate can be used. Since a large number of negative charges are induced in the polymer substrate 130 due to the contact charging phenomenon with the metal, it is preferable to use a material located below the charging column. In addition, it is preferable to use a material having high flexibility in order to produce a rolled material. For example, Kapton film may be used as the material having high flexibility. However, the present invention is not limited thereto.

As the metal layer 140, it is preferable to use a material located on the upper side of the charging column so that positive charge can be induced well during contact charging. The metal material for the metal layer 140 may be, for example, aluminum, but is not limited thereto.

Hereinafter, a manufacturing process of the high-output sliding contact charging electric generator will be described in detail.

First, the metal layer 140 is uniformly deposited on the polymer substrate 130, rolled to have a roll shape, and then fixed to the inner cylinder 110 to which the magnets 120c and 120d are attached. Thereafter, after inserting it into the outer cylinder 100, one end of the polymer substrate 130 is fixed to the outer cylinder 100. Thereafter, a wiring (not shown) can be formed from the inner metal layer 140 to the outside of the outer cylinder 100.

Figs. 2A to 2C illustrate operation concepts of a roll-shaped substrate in a high-output sliding contact charging electric generator according to an embodiment of the present invention. Hereinafter, the operation of the contact charging power generator of the present invention will be described in detail with reference to FIGS. 2A to 2C.

First, as shown in FIG. 2A, the polymer substrate 130, which is charged through sliding, is rolled in a state in which the metal layer 140 is deposited in the initial state.

1, the polymer substrate 130 is wrapped around the inner cylinder 110 so that the inner cylinder 110 is positioned inside the outer cylinder 100. In FIG. 2A, And the outer cylinder 100 are removed to show only the shape of the polymer substrate 130 in more detail.

FIGS. 2B and 2C are diagrams for explaining a case where external energy, for example, vibration or shock, is applied to the polymer substrate 130 in the initial state, which is wound around the inner cylinder 110, 130 are protruded outward and rubbed against the metal layer 140.

2B shows a state in which the inside of the roll-shaped polymer substrate 130 is slid and protrudes in the middle, and FIG. 2C shows a state in which the inside of the polymer substrate 130 is slid and protrudes completely outward will be.

That is, when the inside of the polymer substrate 130 is slid out and protruded as described above, the metal layer 140 of the polymer substrate 130 and the polymer layer are charged by contact charging to generate a potential difference, The electrons are moved to make the potential difference equilibrium.

In the present invention, unlike the conventional sliding-mode contact charging power generator which simply slides on one side, as shown in FIGS. 2B to 2C, since a plurality of surfaces are brought into contact with each other by a single sliding, It can be seen that the area can be widened, and thus the efficiency can be higher than that of the conventional sliding mode contact charging electric generator.

3A and 3B illustrate operation concepts of a high-output sliding contact charging electric generator using a roll shape according to an embodiment of the present invention.

3A, in the present invention, in order to repeatedly slide the polymer substrate 130 as shown in FIGS. 2A to 2C, a polymer substrate having a roll shape (for example, 130 are positioned in the vicinity of the high-output sliding contact charging electric generator, thereby realizing a high-output sliding contact charging electric generator. Such a high-sliding sliding contact charging electric generator using such a roll shape can be manufactured as shown in FIG.

3A, the polymer substrate 130 having the metal layer 140 thereon is rolled so as to have a roll shape on the inner cylinder 110, and then one end of the polymer substrate 130 is connected to the outside The contact charging electric generator is realized by being fixed to the cylinder 100.

In this contact charging power generator, after the polymer substrate 130 rolled in the inner cylinder 110 slides once, the magnets 120a, 120b of the outer cylinder, 120b of the inner cylinder 110 and the magnets 120c, 120d of the inner cylinder 110 may be attached to opposite sides of the respective cylinders so as to face each other.

3B, the polymer substrate 130 can be slid as shown in FIG. 3B by external physical energy, for example, vibrations or shocks, and if the polymer substrate 130 contacts the outer cylinder 100 The magnetic repulsive force may be generated as the distance between the inner cylinder magnets 120c and 120d and the outer cylinder magnets 120a and 120b becomes closer to each other.

3B, the polymer substrate 130 is returned to the initial state as shown in FIG. 3A, and the high-output sliding contact charging electric generator using the roll shape can be brought into an initial state, This operating principle can be used to produce repetitive electrical signals by external repetitive physical motion.

As described above, according to the present invention, in the sliding contact charging electric generator using a roll shape, the metal layer and the polymer layer are electrically charged by contact in such a manner that a film formed by charging a metal layer on the polymer substrate is rolled in a roll form, However, unlike conventional sliding-mode contact-type generators, the polymer and metal layers can be realized in a three-dimensional laminate structure in the form of rolls, so that the contact area between the polymer layer and the metal layer can be widened with a small volume, The output can be increased.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should not be limited by the described embodiments but should be defined by the appended claims.
