Next, the present invention will be described in more detail with reference to specific embodiments of the regenerative power generating device 10 of the present invention.

Figure 3 is a side cross-sectional view showing the operation of the acceleration / running state of the regenerative power generation device 10 carried out in accordance with the present invention, Figure 4 is a deceleration / stop state of the regenerative power generation device 10 implemented in accordance with the present invention Fig. 5 is a front view of the regenerative power generating device 10 in the state of Fig. 4.

3 to 5, the door driver 6 of FIG. 2 blocks the inflow of the driving wind into the air channel 9 by being in close contact with the inlet guide 8 at the inlet of the air channel 9. A door 6a rotatably installed by the door shaft 6b so as to introduce the driving wind into the air channel 9; And a motor 6c which transfers the opening and closing power of the door 6a to the door 6a by a belt, a chain, or a gear arrangement for power transmission.

3 to 5, the rotor blade portion 7 of FIG. 2 is connected to the air channel 9 through which the running wind flows, and from the inlet side of the air channel 9 to the first side wall 9a in the air channel of the running wind. An inlet guide 8 formed to induce inflow, and a first rotary blade 7a rotated by the inlet guide 8 to transmit power to the generator; A first guide 8a for inducing traveling wind from the rear side of the first rotary vane 7a to the second side wall 9b of the air channel 9 opposite the first side wall 9a of the air channel; A second rotary blade 7b which rotates in a direction opposite to the first rotary blade 7a by the driving wind guided by the first guide 8a to transmit power to the generator 2; The 2nd guide 8b which reinduces the travel wind which rotated the 2nd rotary blade 7b to the 1st side wall 9a is comprised so that it may be arrange | positioned repeatedly.

Referring to the operation of the regenerative power generating device 10 of the present invention having the above-described configuration is as follows.

When the car is running, a lot of air passes through it. The above-described regenerative power generating device 10 of the present invention produces electric power by rotating the rotary blades 7al and 7b by using the driving wind generated when the vehicle runs. In this case, the regenerative power generating device 10 of the present invention is characterized in that it operates to minimize energy loss by air resistance. That is, the present invention minimizes the energy loss for regenerative power production by controlling the door 6a to be opened to produce power during deceleration / stop or downhill driving where the energy loss is minimized during the production of regenerative power. .

To this end, the door control unit 5 determines whether to accept the driving wind into the air channel 9 or not to receive the driving wind. To this end, the door control unit 5 adjusts and controls the door according to the driving state of the vehicle (constant speed, deceleration, braking, downhill road, etc.), and in this process, the door is completely closed, partially open, and completely closed according to the driving state of the vehicle. Control by opening, etc.

When the vehicle produces the regenerative power during acceleration or driving, energy loss due to air resistance is generated, so the regenerative power generator 10 does not produce regenerative power.

3 illustrates a state when the vehicle accelerates or runs at constant speed, and the air resistance should be minimized when the vehicle runs at constant speed / acceleration. In particular, in the case of a hybrid vehicle, since the gasoline engine is driven during acceleration and constant speed driving, it is necessary to minimize air interference in order to reduce fuel consumption.

In addition, when the vehicle is decelerating or driving downhill, the driving wind can be used as a braking force, so when the regenerative power is produced, there is no separate energy consumption for the regenerative power production.

In the case of FIG. 3, the door controller 5 receives the speed change of the vehicle and the variable degree of the accelerator as an input to determine whether the current state of the vehicle is constant speed or acceleration. In contrast, the door control unit 5 determines the acceleration and deceleration of the vehicle by the acceleration detection unit 5a.

When the state of the vehicle is determined to be constant speed / acceleration as determined by the door control unit 5, by outputting a motor driving signal for rotating the motor 6c to move the door 6a attached to the door shaft 6b in the closing direction. Blocking the running wind flows into the air channel (9).

On the other hand, when the vehicle is running while decelerating / braking, the door controller 11 monitors the state of the vehicle to open the door 6a. In this case, the deceleration or braking operation is determined by receiving a signal of the brake pedal or a signal from the acceleration sensing unit 5a.

The opening / closing degree of the door 6a at the time of deceleration / braking can also be controlled.In this case, the opening / closing of the door opens the door 6a 100% in the case of a sudden deceleration or braking operation, but at a slow deceleration, the door 6a is decelerated. The opening rate is adjusted from 10% to 90% according to the speed.

When the door 6a is opened, the driving wind flows into the air channel 9 through the inlet guide 8 to rotate the rotary blades 7a and 7b and receive the regenerative power by the generator 2 receiving the power of the rotary blades. Will produce.

In the case of the generator 2 described above, the rotating shaft may be connected to one shaft end of the rotary blades 7a and 7b, and the other rotating shaft is supported by the supporter bearing 2a (see FIG. 5).

The state in which the door 6a is opened is divided into three types.

First is the deceleration of the car. At this time, the purpose of reducing the speed of the car is to open the door (6a) to increase the air resistance. At the same time, the rotary blades 7a and 7b are turned by using the driving wind coming in by opening the door 6a, so that regenerative power is produced by the generator 2 connected to the rotary shafts of the rotary blades 7a and 7b.

Second is the braking of the car. Meaning that the driver starts to brake is aimed at reducing the speed of the car. In this case, when the regenerative power is produced by opening the door 6a, the regenerative power can be produced using the driving wind, and the air resistance caused by the driving wind can be used as the braking force, thereby consuming no energy for the regenerative power production. .

Third, when the car is driving downhill. At this time, the speed of the car is automatically increased by the gravity of the car. By using the driving wind generated by the extra energy caused by gravity, the regenerative power is produced and the braking force on the downhill can be used to increase the energy use efficiency.

In addition, the rotary blade portion 7 of the present invention, so that the rotary blades (7a, 7b) are arranged in succession to rotate in the opposite direction, the wind direction in the air channel of the running wind of the rotary blades (7a, 7b) It has a structure which remarkably improves the rotational efficiency of the rotary blade by running wind by making it guide to a rotation direction. Thereby, the regenerative electric power production efficiency by running wind improves remarkably.

The present invention as described above, by generating the regenerative power by using the driving wind generated during the deceleration / stop or downhill driving of a car, such as to minimize the energy consumption for generating the regenerative power, as well as to significantly improve the idle energy utilization efficiency. Provide effect.

In addition, the present invention described above provides the effect of significantly improving the regenerative power production efficiency by maximizing the rotational force of the rotary blades in the driving wind by rotating the rotation blades arranged in succession in the opposite direction alternately for the production of regenerative power.

In addition, the present invention described above generates and stores the regenerative power by using the idle energy generated during deceleration, braking and downhill driving, and then runs by using the stored power during acceleration or constant speed driving. It also provides a significant improvement.
