Description

Description Technical field of vehicles with wind power generators

The present invention relates to a vehicle with a power generation device. Background art

Generally, in the field of vehicles as a means of transportation, computerization is progressing, and it is no exaggeration to say that today's vehicles are a collection of electronic components. Taking a car as an example, in addition to installing electric mirrors and windows, the use of increasingly sophisticated car audio and power navigation systems is becoming widespread. With such computerization, the amount of power consumed by vehicles is increasing.

In recent years, environmental issues and energy issues have been taken up on a global scale, and electric vehicles are attracting attention in the vehicle field. An electric vehicle is an electric vehicle that runs on electric power, and runs on a motor instead of an internal combustion engine that uses fuel. This electric vehicle has the following advantages.

①High energy use efficiency.

No idling is required, and there is no energy consumption because the motor stops when the vehicle is stopped, such as when waiting for a traffic light or congestion. It is also possible to convert kinetic energy to electrical energy by switching the motor to a generator during deceleration.

2) No exhaust gas is emitted, and there is no pollution.

It does not emit C02, which causes global warming, or gas that pollutes the atmosphere. Therefore, no muffler is needed. Also, low noise and low vibration can be realized.

③ The structure is simple.

Since the rotational force of the motor is used directly, complicated mechanisms such as transmissions and differential gears are not required. Since there is no complicated mechanism, it is unlikely to break down.

Electric vehicles with the above advantages are promising alternatives to gasoline vehicles The research and development are being advanced. Specifically, since it is very important for electric vehicles to determine how long they can run on a single charge, efforts are being made to reduce vehicle weight and improve battery performance.

However, as mentioned above, current vehicles require a great deal of power. In particular, the amount of power consumed by electric vehicles running on electric energy is enormous, and the development of technology that incorporates as much power as possible into vehicles has been awaited.

The present invention has been proposed in view of such a situation, and its purpose is to generate electric power using wind generated when the vehicle runs, and to take in the electric power to provide sufficient electric power to the vehicle. It is an object of the present invention to provide a vehicle with a wind power generator that can be secured. Disclosure of the invention

The present invention relates to a vehicle having a motor for supplying electric power to an electric system of the vehicle, and a battery for supplying electric power to the motor, wherein the electric power is generated by taking in wind generated when the vehicle runs. And a control device for controlling the wind power generation device.

According to the present invention, when the vehicle runs, wind is generated around the vehicle. The wind is taken in and the wind power generator generates electric power. Then, the wind power generator sends the generated power to the battery. The battery can store this power and supply power to the motor when the motor operates.

Further, according to the present invention, the wind power generator can be operated only when the vehicle is decelerated by the operation of the control device. Thereby, the load at the time of driving the wind power generator can be used for the deceleration energy of the vehicle.

Further, the present invention provides the vehicle with the improved wind power generator described above, further comprising an engine generator that burns fuel internally to generate electric power and sends the generated electric power to the battery. And

According to the present invention, in addition to the operation of the vehicle with the improved wind power generator described above, Thus, electric power can be obtained from the engine generator. As a result, power can always be sent stably to the battery. Therefore, the motor can be operated reliably, and the reliability of securing electric power is improved.

This embodiment will be described with reference to FIGS. FIG. 1 is a structural view of an automobile to which the present invention is applied, FIG. 2 is a plan view of a wind power generator according to the present embodiment, and FIG. 3 is a circuit diagram of the present embodiment.

[overall structure]

As shown in Fig. 1, two wind turbines 2, 2 are installed in parallel on the roof of a car 1. The wind power generator 2 is disposed so that its longitudinal direction is parallel to the front-rear direction of the vehicle 1 and that the rear end is raised at an angle of about 5 degrees more than the front end. Further, the vehicle 1 has a built-in control device 4 for controlling the battery 3 and the wind power generator 2, and the battery 3 and the control device 4 are electrically connected to the wind power generator 2. Battery 3 is nickel It consists of a hydrogen storage battery and a lithium-ion battery, and supplies power to the motor 7 (shown in Fig. 3) that supplies power to the electric system of the car 1.

[Wind power generator]

As shown in FIG. 2, the wind power generator 2 includes a cylindrical duct 2a. At substantially the center of the duct 2a, a support portion 2b is set up in the direction of the central axis, and a main body 2c of the power generator is fixed here. A propeller 2 d that rotates by receiving wind is provided on the front end side of the main body 2 c of the power generating device, and is configured to obtain electric power by rotating the propeller 2 d. At the front end of the cylindrical duct 2a, an air inlet 10 is formed which extends outward at an angle of about 5 degrees. The front shape of the air intake 10 is a circular shape with the top and bottom collapsed as shown in Fig. 10 (A) to prevent the duct 2a from floating.

[Electrical configuration]

As mentioned earlier, the wind power generator 2 and the control device 4 are connected to the battery 3, but as shown in Fig. 3, the speed control circuit 9 controls the speed and torque according to the degree of stepping on the motor 7 and the accelerator 8. Are also electrically connected.

[Effect]

In the present embodiment having the above-described configuration, wind generated when the vehicle 1 runs is introduced into the duct 2a from the air intake 10. At this time, the wind flows so as to pass through the duct 2a as shown in FIG. The wind rotates the propeller 2d, and the main body 2c of the wind power generator operates to generate electric power. Then, the wind turbine generator 2 sends the generated power to the battery 3. The battery 3 stores this electric power and supplies electric power to the motor 7 when the motor 7 operates. As described above, according to the present embodiment, the wind power generation device 2 can be operated by the wind generated when the vehicle 1 travels, and the generated power can be stored in the battery 3. can do. Further, since the rear end of the wind power generator 2 is lifted more than the front end, it is possible to prevent the front end from being lifted by wind force. That is, the wind power generator 2 can also serve as an air stabilizer.

Furthermore, in the present embodiment, the operation of the wind turbine generator 2 Timing can be controlled. For example, the control device 4 is configured so that the rotational force of the propeller 2d is not transmitted to the main body 2c of the wind power generator during acceleration of the vehicle 1. In this way, even when the propeller 2 d rotates, the load for driving the wind turbine generator 2 is not applied to the vehicle 1, and smooth acceleration can be performed. On the other hand, if the control device 4 is configured so that the rotational force of the propeller 2 d is transmitted to the main body 2 c of the wind power generator when the vehicle 1 is moving at a low speed or when the car 1 runs downhill, the wind power generator 2 The load at the time of driving can be used as energy for decelerating the electric vehicle 1.

Note that a stop lamp can be attached to the roof of the vehicle 1 near the wind power generator 2. Since the stop lamp is installed at a high position, it is not only easily recognized by high-elevation vehicles such as trucks and trucks running behind it, but also because it is close to the generator 2, electrical wiring is easy and easy. It can be installed in
