Description

External magnetic induction power generation device

technical field

The utility model relates to an external magnetic induction power generation device, in particular to an external magnetic induction power generation device which utilizes the wheels of vehicles (automobiles, locomotives, bicycles, etc.) to generate out-wheel (out-wheel) power generation.

Background technique

Since the industrial revolution, human life and economy have relied on fossil fuels as power generation and transportation for rapid development. However, fossil fuels also cause air pollution, and greenhouse gas emissions such as CO ₂ produce a greenhouse effect and cause global warming. According to IEA (2007) According to statistics, 46% of man-made greenhouse gas emission sources are power plants, and 23% of traffic pollution emissions (including 73% of land traffic). All come directly or indirectly from fossil fuels, such as internal combustion engine (engine) vehicles that directly use diesel, gasoline, and natural gas, because internal combustion engines cannot completely convert the chemical energy of fossil fuels into mechanical energy for driving vehicles, and the energy generated by internal combustion engines will be due to Body weight/riding load, friction loss, exhaust suction loss, improper air-oil ratio, incomplete combustion and exhaust heat loss, heat loss from engine idling, so that only 13%-20% of the energy of fossil fuels can be used in energy In the drive of automobiles, gas-powered vehicles, plug-in electric vehicles, and rechargeable battery-driven vehicles indirectly use fossil fuels. These electric vehicles all transfer CO ₂ emissions to power plants, because their electricity comes from thermal power plants and other power plants, and Power plants still use oil, coal, and natural gas to generate electricity. Therefore, if electric vehicles are charged during off-peak hours, zero emissions or emission reductions can be achieved. Otherwise, charging electric vehicles during peak hours will cause thermal power plants to More _CO2 and other greenhouse gases are emitted, and limited by the storage capacity and storage time of the battery, the lack of battery life and the establishment of charging stations all make electric vehicles less efficient.

According to the principle of electromagnetic induction in electromagnetism, as long as the rotor and stator with magnetism or conductors conduct circular linear induction with each other, electricity can be generated, and the vehicle has the basic components of rotor (wheel) and stator (body), so as long as the design A set of simple, lightweight, safe and economical electromagnetic induction components can use the wheels of vehicles (bicycles, motorcycles, cars, buses, connected vehicles, etc.) The formed transportation power network, the electricity generated by it will become a solution for human beings to maintain economic development and the sustainable development of the earth; however, the existing methods of using vehicles to generate electricity can be roughly divided into three categories:

(1) The bottle dynamo of the bicycle is a wine bottle-shaped power generation device. The rubber on the bottle head is used to rub the bicycle tire or frame, etc., and the mechanical energy of the friction drives the magnet rotor of the bottle generator and The coil stator interacts with induction to generate 6V3W power for lighting at night.

(2) The Hub Dynamo of the bicycle, in order to solve the shortcomings of the traditional grinding wheel power generation that needs to rub against the bicycle tire or frame, resulting in resistance that affects the speed of the bicycle and mechanical friction that causes tire damage, etc., the manufacturer designed it on the hub of the bicycle, or Magnets and coils are installed in the wheel drum or the axle, so that the axle becomes a coil stator, while the hub is equipped with a magnet as a rotor, and electromagnetic induction is generated by the circular motion of the permanent magnet rotor on the hub or wheel drum and the axle coil stator. To generate 6V3W power. Due to the small size of the wheel drum power generation method, the solid power generation is low.

(3) Automobile and motorcycle rim motors and brakes regenerate power generation. In order to solve the above-mentioned problem of small size of bicycle wheel drums, automobile and motorcycle manufacturers add motors to tires or rims in the form of direct drive. It is called an in-wheel motor. After the power is supplied, the wheels rotate to drive the motorcycle forward, but when the brakes and downhill brakes are decelerated, the motor is converted into a power generation mode to charge the battery to increase by 30%. endurance.

The existing grinding wheel, wheel drum, and in-wheel motor brake regenerative power generation have low power generation efficiency, because these power generation methods are limited by space, magnet size, coil diameter and number of turns, because they need to be used in smaller rims Or it will be difficult to put a large number of magnets or coils in the wheel drum, and the power recovery efficiency of the brake regeneration system is only 30%, so the basic technical concept of the in-wheel (in-wheel) has great room for improvement.

Furthermore, the core of the problem of the low power generation efficiency of the existing grinding wheels, wheel drums and in-wheel motors plus braking regenerative power generation is: using a very small part of the wheel to obtain a very small power supply, such as the grinding wheel of the 26-hour wheel Compared with the drum power generation device, the area of the drum of the grinding wheel is less than two inches in the available electromagnetic induction area of 26 o'clock, and the space for installing permanent magnets and coils in the drum of two o'clock is limited. , so it can only generate 6V3W of electricity, and the in-wheel motor of the automobile and motorcycle has a large volume, but its electric energy will be consumed by the weight of the vehicle body or converted into energy such as frictional heat loss, and the torque of the motor is only converted into Regenerative power generation, therefore, the power generation is only 30%. For example, the EBOX car of the American Acpropulsion company is driven by a 120KW AC motor, and the 20KW power is stored back into the lithium battery through the brake regeneration method, and the energy usage rate is low.

Utility model content

In view of the above-mentioned problems and needs, the designer hopes to use the wheels of traditional internal combustion engine vehicles, hybrid vehicles, pure electric vehicles, pneumatic vehicles, etc. The magnetic induction power generation device generates electricity, because no matter what kind of vehicle, there are more than 2-4 wheels, which are basically equipped with the outside of the wheels, and the permanent magnets and coil stators can be installed externally for electromagnetic induction. Through the wheel steering and The driving mechanical energy and the inertial transmission energy drive the electromagnetic induction to generate electricity.

If the battery has excess power after completing the traffic trip, it can be transformed into AC power for household loads, such as lighting and air conditioning. , TV, computer entertainment, electric water heater, etc., or return to the public power grid of the power company through the electricity resale network through the meter, so that each vehicle can store 1KW (bicycle) 5KW (motorcycle) 20KW (car) ) 50KW (buses, trailers, etc.), it can generate nearly one million kilowatt-hours (degrees) of electricity every day, which can greatly reduce CO ₂ emissions from fossil fuel (oil, coal, natural gas) power plants.

Among the means of transportation, the wheel diameter of bicycle is relatively large (26 o'clock), the area that can be installed with permanent magnet is large, and the area that can be installed with coil stator is also large. The wheel) is changed from the circular motion of the wheel to linear motion through ground friction, and the reversing wheel (front wheel) is driven to move forward by inertia through the connection of the car body. The rotating stator, or the coil stator of the front fork or the rear fork can perform interactive electromagnetic induction to generate electricity.
