Description

The present invention relates to a wind power generation vehicle equipped with a wind receiving passage duct that receives a traveling wind and a wind turbine for generating electricity that receives and rotates the traveling wind, and in particular, the entire length from the front surface to the rear back surface inside the vehicle body. And a plurality of wind turbines for power generation installed from the front to the rear inside the wind receiving passage duct are rotated by running wind, thereby generating and storing power more efficiently. It relates to possible wind power electric vehicles.

From the viewpoints of environmental conservation and resource securing, technologies for suppressing exhaust gases that adversely affect global warming, such as carbon dioxide, have been developed. In addition, in order to reduce fossil fuel consumption, development of hybrid vehicles combined with gasoline drive and research on drive devices that replace internal combustion engines that do not use fossil fuels such as gasoline and light oil are being conducted, and matching with various energy sources Has been studied.
Among them, wind power generation is a power generation technology that has been developed for a long time, but has recently attracted attention again, and is used in various fields as a power generation method applying natural force. In addition, since automobiles receive traveling wind from the front when traveling, the research and development of automobiles that run while being charged with electricity generated by the installed wind power generator are being actively conducted.

  In the development of electric vehicles using wind power generation, the energy density per unit mass of existing batteries is much lower than that of fossil fuels such as gasoline, so an internal combustion engine that uses fossil fuels in a single charge is used as the power source. In order to secure a mileage equivalent to that of a car, a battery with a large capacity must be unexpectedly installed, which leads to an extreme increase in vehicle weight. Therefore, while driving using the stored electricity and charging while generating electricity during driving, the reduction in the amount of stored electricity is minimized, and the distance that can be driven with one charge is maximized. Various devices are considered.

  For automobiles using ordinary wind power generation, a structure in which one or several windmills are installed on the chassis, frame, and body of a conventional automobile has already been considered. However, since wind power generation is small, even if only a small number of wind turbines of a size that can be installed inside the body of an automobile are installed, they can be stored while being charged due to the effect of wind power generation by running wind. It was difficult to achieve long-distance driving by car.

  In addition, in order to install a wind turbine for power generation in a conventional automobile, there are many restrictions on the installation location of wind turbines and the number of wind turbines that can be installed, and since only a very small number of wind turbines can be installed, the amount of power generation is small and efficient. It was difficult to store the secondary battery. Therefore, it is a windmill of a size that can be installed inside the car body without changing the appearance of the automobile, and it has a structure that can install many windmills to obtain a sufficient amount of power generation The development of electric vehicles was awaited.

It is a rear view of the wind power generation electric vehicle which concerns on this invention. It is a perspective view of the wind receiving passage duct concerning the present invention.

Hereinafter, a wind power generation electric vehicle according to the present invention will be described in detail with reference to the drawings.
A wind power generation electric vehicle 10 of the present invention includes an existing wind passage duct 20, a windmill 30, and a body 40 of a vehicle body provided in a part of a chassis that is a frame of a vehicle body. Thus, a plurality of windmills are installed inside in order to generate power more efficiently by using wind during traveling.

FIG. 1 is a side view of an example of a wind power generation electric vehicle of the present invention, and FIG. 2 is a front view of the same. FIG. 3 is a perspective view of the wind-receiving passage duct that is not incorporated in the chassis.
The wind-powered automobile 10 includes a wind receiving passage duct 20, a windmill 30, a body 40, a driving device 50, wheels 60 and 62, and a secondary battery 70, and has a rectangular cross section as a part of the bottom chassis 22 ( A plurality of (hollow) wind-receiving passage ducts are installed in a line corresponding to the width of the vehicle in a straight line penetrating through the bottom surface of the vehicle over the entire length from the front surface to the rear back surface inside the vehicle body. One or more appropriate numbers are selected according to the width of the vehicle, and the total length is set to an appropriate length according to the vehicle.

The wind-receiving passage duct 20 has a length corresponding to the entire length of the vehicle. In this embodiment, the wind-receiving duct 20 is a hollow duct having a square section of 18 cm × 18 cm made of an aluminum material, and the axle width serving as the vehicle width of the vehicle. A plurality of pieces that can be installed in parallel are arranged in parallel, and a vehicle is formed integrally with the chassis 22 that is an outer frame. In this embodiment, the cross section of the wind receiving passage duct 20 is formed in a square shape, but is not limited to a square shape, and may be a rectangular shape or a windmill shape or a storage battery, a drive device or other mounted object. It is also possible to make a substantially semicircular duct with rounded corners according to the above. In this embodiment, the wind-receiving passage duct is formed with the same width over the entire length of the vehicle.

In another embodiment of the present invention, the wind-receiving passage duct has a structure in which the suction port portion at the front end of the vehicle is widened in a trumpet shape so that more air can be taken in. As still another embodiment, the structure of the wind receiving passage duct is a taper-shaped cross-sectional square tube in which one side of the cross section gradually decreases over the entire length from the suction port at the front end of the vehicle to the discharge port at the rear end of the vehicle. It is also possible to configure the shape (hollow).
A plurality of wind-receiving passage ducts that are tapered at the front end or tapered from the front to the rear of the vehicle body in parallel with the axle width as described above are arranged in parallel. By arranging it, it is also possible to form a substantially fan-shaped space inside the vehicle and install a windmill inside each wind receiving passage duct.
Furthermore, a configuration in which a trumpet-shaped protrusion is additionally installed at the tip of the wind receiving passage duct formed with the same width is also possible.

The wind turbine 30 for power generation is equipped with a conventional power generation mechanism that converts rotational energy into electric power, and receives the traveling wind that is taken in from the inlet 26 of the duct and discharged from the outlet 28 during traveling. A wind turbine receiving blade (paddle) 32 rotates to generate electricity. In the present embodiment, a paddle type windmill is shown in which hemispherical cups, which are three wind receiving blades (paddles) 32, are connected to the arm of the rotary shaft. In addition, other vertical axis winds such as a gyro mill type or horizontal axis wind turbines such as a propeller type can be used, which are limited to the paddle type wind turbines for power generation shown in this embodiment. is not.

  The windmill 30 is arranged in a space 24 inside the duct formed over the entire length from the front surface of the vehicle body to the rear back surface inside each wind receiving passage duct 20 formed integrally with the chassis 22, and from the front. Several windmills are installed in a row in the rear. Moreover, it is also possible to install in multiple rows according to the shape of the wind receiving passage duct. The windmill is installed in the duct internal space 24 with the center axis of the windmill and the center axis of the other windmill at 20 cm intervals. Note that the installation interval between the windmill and the windmill is arbitrarily changed depending on the characteristics of the windmill or the output of the car.

Conventionally, since the number of wind turbines that can be mounted on a vehicle is very limited, the amount of power generation is limited. However, the wind power generation electric vehicle of the present invention has a plurality of small-diameter wind turbines for wind power generation with a small amount of power generation. Since it is mounted in the body as much as possible, a large amount of power generation capacity can be obtained without impairing the appearance of the car itself. By incorporating the duct for installing the windmill into the chassis, the wind from the front is received properly, so the wind speed is strong and the power generation efficiency can be improved.

Since a large amount of electric power is required at the time of starting the vehicle, the vehicle is started by moving a driving device such as a motor for driving wheels using electric power charged in advance from a plug or the like and stored in a battery. When the battery is sufficiently charged during traveling, the power generated by the windmill is stored for the subsequent starting, and is used for starting and traveling. Large purpose of charging and storing surplus electric power generated by using strong winds received during stable driving, and improving the storage capacity, which has been a problem for electric vehicles, and dramatically extending the continuous driving distance of vehicles Is easily achieved.

The wind receiving passage duct 20 is provided with a notch or a branch pipe extending from a part of the wind receiving passage duct 20 to the storage battery, so that the traveling wind that is taken in from the traveling wind intake port and flows to the discharge port can be converted into the storage battery and the associated power storage. By flowing to the system, it can also function as a cooling device for a storage battery that generates heat by using or charging stored electricity. Moreover, it is a structure which functions also as an apparatus which cools the rotation part of the windmill which heat | fever-generates by rotation by driving | running | working wind.

  The secondary battery 70 has a small memory effect, can be recharged, has a high energy density, has no dendrite problem, and uses a lithium ion secondary battery with little self-discharge. Due to the characteristics of lithium ions, secondary batteries that use them can eliminate the memory effect of the battery, which has been a problem in the past. There is no need to strictly check the capacity. In addition, it can be recharged frequently without hesitation and can easily create a state where it is always fully charged. In addition, because the storage battery has a high energy density, the weight of the storage battery mounted on the vehicle is reduced and the weight of the battery, which has been increased in size to secure the storage capacity, has had a large impact on the vehicle weight. By being reduced in size, it has a structure that makes it possible to extend the continuous travel distance with the same power generation and charge amount.

  In the present embodiment, the secondary battery 70 is configured to be installed at the bottom of a plurality of wind receiving passage ducts integrally formed with the chassis. By disposing a heavy storage battery under the floor, the center of gravity of the entire vehicle is lowered, so that vehicle stability is improved. In addition, since the lithium ion battery has a large capacity, is compact, and is lighter than a conventional battery, it can be installed not only at the bottom of the wind receiving passage duct provided in the chassis but also at various places.

The motor as a driving device that is a driving source of the vehicle may have a structure provided outside the wheel, but may be an in-wheel motor that is directly mounted inside the wheel. The drive device used may be a hub motor that is integrated with the wheel hub. By placing the drive device in the wheel, the number of parts that must be mounted on the chassis can be greatly reduced, so it is possible to easily install the wind-receiving passage duct over the entire length of the vehicle body. It becomes possible.

The in-wheel motor consumes the drive power of the drive device generated by electricity until the power is transmitted to the wheels because the power is transmitted almost directly to the wheels without passing through the gear mechanism or drive shaft required for general automobiles. Loss of energy is reduced, and by omitting parts such as the engine, gears, and shafts, the mechanism of the entire vehicle can be simplified. As a result, not only the electric power used for running is reduced due to the weight reduction, but also a configuration that can easily perform breakdowns, maintenance, and the like.

Although not shown in the drawing of the present embodiment, a plurality of wind turbines installed in the wind receiving passage duct suspends the sound generating flakes of the wing shape to generate wind noise or boo-boo sound. It can be set as the structure provided with sound generation functions, such as. Since the driving sound of hybrid vehicles and electric vehicles is too quiet and there is no warning sound like engine sound, it is a problem that is considered to be dangerous. It was announced. Also in the wind power generation electric vehicle according to the present invention, since the running sound at a low speed is very quiet as compared with a vehicle equipped with a gasoline engine, the driving wind generated at the time of driving is used to alert a pedestrian. It is possible to generate a warning sound. As a sound generating device during low-speed running, an extremely simple drooping film that cannot be used at high speeds or a “beat” attached to a kite, or an inexpensive device such as a wind chime can be considered.
The means for generating a warning sound is not limited to the above-mentioned methods, and a structure is provided in which a whistle that emits a sound at a low speed is installed at an arbitrary position of the wind receiving passage duct to generate sound by the wind pressure of the traveling wind. It is also possible.
