Abstract

PURPOSE:To have an energy-saving effect spontaneously only by installation of simple parts by making a generator of an energy-saving type by a relatively simple method wherein inertia energy of an engine and car body at the time of deceleration is recycled and applied for charging a battery. CONSTITUTION:A control switch 6 is connected to an acceleration pedal 8 interlocked with a carburetter 7, and when the pedal 8 is pressed down to work the carburetter 7 for acceleration, the switch 6 is put OFF to prevent a current from flowing in a field coil 2, which allows a generator to cause no generation. When pressing down of the pedal is moderated to perform deceleration, on the other hand, a control switch 5 is turned ON to flow a current in the coil to thereby generate AC voltage, which is rectified by a rectifyer 4 and charged to a battery 5. A load 9 of electric apparatus is managed with discharge of the battery 5 during acceleration drive while it is managed with a generator 1 during deceleration, and an excessive power is charged to the battery 5.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to energy saving in automobiles, and is a method for converting inertial energy, which was wasted as heat loss during automobile deceleration, into electrical energy and regenerating it.

<Conventional technology> Conventional charging generators charge the battery by detecting and adjusting the voltage of the electric circuit that represents the amount of electricity used by all the electric devices of the car and the state of charge of the storage battery, regardless of the driving state of the car. Therefore, in this case, the generator was driven by the engine regardless of the vehicle's driving condition.

Problems that this idea aims to solve FIG. 1 is a diagram showing the driving modes of an automobile.

The driving modes of automobiles are roughly divided into acceleration driving where the vehicle speed increases over time, constant speed driving where the vehicle speed is constant, and deceleration driving where the vehicle speed slows down. The running resistance becomes maximum when the vehicle is accelerating as the accelerating force is added to the constant speed running resistance. However, when a car decelerates, it is necessary to dissipate the inertial energy of the car as heat loss through negative running resistance, that is, engine braking or friction braking. However, the friction brake wears out at this time.

On the other hand, conventionally, the generator generates the amount of electricity used by electrical equipment and the amount of electricity to charge the battery, regardless of whether the car accelerates or decelerates, so even when the car accelerates, the load of the generator is applied to the engine, causing acceleration. It was degrading performance.

As shown in Fig. 1, energy loss occurs even with one acceleration/deceleration, but since automobiles accelerate/decelerate frequently, the energy loss due to acceleration/deceleration and the loss due to wear are enormous.

The present invention aims to regenerate and utilize such energy loss to help save energy.

<Means for Solving the Problems> The present invention converts inertial energy, which was conventionally wasted as heat loss when an automobile decelerates, into reusable electrical energy using a generator in order to reuse as much as possible. This electrical energy is then reused for electrical devices such as ignition devices and lighting devices during acceleration and constant speed driving.

The present invention is a method that achieves both energy saving and brake wear prevention by forming an electric circuit so that power is generated mainly during deceleration, without generating power during acceleration or constant speed driving.

Function> The present invention mainly generates electricity when the car decelerates and charges the battery, so the kinetic energy of the car that is lost as heat during deceleration can be reused as electrical energy for electrical devices. At times, the load of the generator is not applied to the engine, resulting in an energy-saving vehicle with good acceleration performance.

<Embodiment> FIG. 2 shows an embodiment of a basic electrical circuit for power generation during deceleration according to the present invention.

The generator 1 includes a field coil 2, a stator coil 3, and a rectifier 4, and is connected to a battery 5, an electrical device load 9, and a control switch 6 by conductive wires.

The control switch 6 is connected to an accelerator pedal 8 which is mechanically connected to a carburetor (fuel injection pump) 7, and when the accelerator pedal 8 is depressed to operate the carburetor (fuel injection pump) 7 and accelerate the car, The control switch 6 is turned OFF, and no current flows through the field coil 2 and no power is generated.

Conversely, when the accelerator pedal 8 is released to decelerate, the control switch 5 is turned on and current flows through the field coil 2, generating an alternating current voltage in the stator coil 3, which is rectified by the rectifier 4 and charged into the battery 5. Ru.

Therefore, when the automobile is accelerating, the electric device load 9 is covered by the discharge of the battery 5, and when the automobile is decelerating, it is covered by the power generated by the generator 1, and the battery 5 is charged with surplus electric power.

When driving at a constant speed, the control switch 6 can be set to switch to either mode. .

Furthermore, since the load on the electrical equipment is different during the night and during the day, the power generation amount can be automatically adjusted by feeding back the remaining charge of the battery 5 to the control switch 6.

This embodiment is a basic embodiment of the present invention, and includes a method for charging a battery from a generator, connection with other electric circuits,
Connection with a brake and application of a control computer are also within the scope of the present invention.

<Effects of the Invention> The present invention converts the inertial energy possessed by a car, which was conventionally discarded as heat loss during deceleration, into electrical energy using a charging generator, and charges the battery once during acceleration and constant speed driving. This is a method of regenerating and discharging electrical equipment as a load, and it is possible to make an energy-saving car with a relatively simple and inexpensive device, and it can also be used in cars currently in use by installing simple parts. This is a useful invention because it can immediately achieve an energy saving effect.

Furthermore, since the engine output during acceleration and constant speed driving is not used for power generation, acceleration performance is improved.

Furthermore, the problem of wear of conventional friction brakes is reduced, making it possible to create comfortable and energy-saving automobiles.
