Description

Driving force augmentation device using magnetic force

The present invention relates to a driving force enhancing device using magnetic force, and more particularly, to a driving force enhancing device using magnetic force capable of increasing the driving force of a bicycle by using the repulsive force of magnets having the same polarity and the attractive force of magnets having different polarities. it's all about

Referring to the background art described in Korean Patent Registration No. 10-1574144, fossil fuels such as gasoline, diesel, and coal are generally used as a power source for an engine generating rotational force or a generator generating electricity.

These fossil fuels pollute the environment by emitting various environmental pollutants such as carbon monoxide, carbon dioxide, and nitrogen oxide, which is pointed out as the main cause of environmental pollution such as global warming. have.

Accordingly, the development of various renewable energy resources to replace them is being promoted at the global level. For example, new energies such as hydrogen energy and fuel cells are currently being developed for practical use due to technical limitations, and natural energies such as solar heat and wind power are highly dependent on natural conditions, making it impossible to supply stable energy.

Therefore, there is an urgent need to overcome the limitations of fossil energy and existing renewable energy and to discover energy resources that can stably supply energy. From this point of view, magnetic force can be an alternative to solving these two problems at the same time.

In general, permanent magnets are always composed of an N pole and an S pole, and depending on the polarity, repulsive force acts between the same polarities, and attractive force acts between different polarities. Therefore, since objects having polarity generate attraction or repulsive force according to the polarity of the surfaces facing each other, the magnetic force corresponding to the sum of attraction and repulsion can be converted into mechanical energy by properly combining them.

The magnetic force of these permanent magnets is a kind of natural energy resource that exists in the natural world. Magnetic force is rarely used as a conventional power source other than these simple uses, but it can be converted into mechanical energy by properly arranging the magnets, and can be used for various power generating devices. can be used as a driving source.

On the other hand, the development of power generators using permanent magnets has been attempted by many people for a long time, but no practical results have been achieved. For example, Patent Registration No. 10-0740560 'Power Generator and Method Using Permanent Magnet', Patent Registration No. 10-0907723 'Linear Power Device Using Magnet', Patent Publication No. 2000-0010065 ' A 'generator using permanent magnet' and 'automatic rotation motor using permanent magnet' of Publicated Patent No. 2001-0109891 have been proposed.

However, such a conventional technology has a problem in that the efficiency of the system is low, as it is derived from the misperception that a power generator can be configured using only repulsive force and attractive force, which are basic properties of permanent magnets acting on each other.

In addition, most of the power generators that generate power until now have used fossil fuels such as gasoline, diesel, and coal as a power source. However, these fossil fuels have problems such as emission of environmental pollutants such as carbon monoxide and carbon dioxide, which are the main culprits of global warming, and international disputes due to limitations in endowments and regional differences. It is being highlighted as a challenge.
