Description

WIND ENERGY GENERATING EQUIPMENT FOR VEHICLES ELECTRICAL

OBJECT OF THE INVENTION

The invention, as expressed in the wording of the present specification, refers to a wind power generating equipment for electric vehicles, providing the function for which it is intended, several advantages and novelty characteristics that will be described in detail later and which represent a remarkable improvement in the current state of the art.

More in particular, the object of the invention focuses on an electrical energy generating equipment designed for the use by means of electronic control of the eolic energy of the wind generated by the movement of the vehicle in which it is installed, being applicable for the recharging of the batteries or for direct power supply of the electric motor of any electric or hybrid vehicle.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is framed within the automotive sector, focusing on the field of electrical energy generating apparatus, equipment and devices applicable to said sector, specifically wind-type generators.

BACKGROUND OF THE INVENTION

As a reference to the current state of the art, it should be noted that, although some devices or systems for taking advantage of the

by part of the applicant, I know unknown the

existence of any wind power-generating equipment for electric vehicles or invention of similar application that presents technical, structural and constitutive characteristics similar to those presented herein, as claimed.

EXPLANATION OF THE INVENTION

Specifically, what the invention proposes, as has already been pointed out above, is a wind power generating equipment for electric vehicles by means of which the use of the wind generated by the movement of the vehicle for the generation of electric energy is achieved, being suitable to be applicable in any electric or hybrid vehicle.

The function of the equipment is to take advantage of the energy of the wind produced in the front part of the vehicle, allowing its exit through the lower part of the vehicle or through the sides.

Energy. generated electricity can be used to charge the batteries of the

vehicle, or even for direct power supply to the electric motor, in case of electrical compatibility.

For this, the recommended equipment essentially comprises a wind rotor that uses the lifting force of the wind, making use of a wing profile.

or group of blades, which can be like that of Darrieus type rotors, that is, spindle-shaped blades,

or like that of the Giromill type rotors, that is, with straight blades, but in both cases with the rotor shaft arranged horizontally at the front of the vehicle, behind the front grill.

According to another characteristic of the invention, the equipment contemplates the incorporation of at least two electric current generators, one for low speeds and the other for high speeds, which can be used independently or together.

In addition, a coupling between the axis of said generators and the axis of the rotor is contemplated which, by means of Electronic control, allows the synchronization between both and their physical connection, acting, at the same time, as a reducer or multiplier, normally as a reducer.

According to another characteristic of the invention, the equipment contemplates the existence of folding blades that are electronically controlled, to regulate the speed of the air entering the rotor and keep it constant regardless of the speed of movement of the vehicle. To do this, said blades are configured to cause the Venturi effect and achieve an increase in air speed when the vehicle circulates at low speeds, or to completely divert said air so that it does not go directly to the rotor in order not to cause damage. in the system for speeding.

Additionally, the equipment has an anemometer for the real reading of the speed of the

wind. The data obtained is passed to a control circuit that the equipment has and which is the one that regulates the entire system: obtaining data from the anemometer, opening or closing of the folding sheets,

or from both of them, by mediation of the Coupling from

rotor.

In addition, logically, it also has all the power electronics necessary to adapt it to the vehicle's battery charge (rectification stage, accumulators, stabilizers ...).

Finally, it is worth mentioning that, since wind energy has the property that the maximum energy that can be taken from the wind is 59% of its total energy, having to have space for the passage of the rest of the energy, that is, for the remaining 41% (and which is what is known as Betz's Law), the lower folding blades can be retracted in order to be able to comply with said Betz's Law, making 59% of the incoming air or wind impact on the rotor wind power, and allowing the remaining air or wind to escape through the lower part of the vehicle, through a grid provided for this purpose.

The described wind power generating equipment for electric vehicles represents, therefore, an innovative structure of hitherto unknown characteristics for this purpose, reasons that, together with its practical utility, provide it with a sufficient basis to obtain the privilege of exclusivity that is requested.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made of the invention, and to help a better understanding of the characteristics that distinguish it, the present specification is accompanied, as an integral part thereof, by a set of drawings, in which with Illustrative and non-limiting character, the following has been represented:

Figures 3 to 6.- Show respective sectional views of the side elevation of the vehicle, showing the profile of the rotor blades and different positions that the folding blades take to regulate the air intake. Specifically, Figure 3 shows the upper sheet and the lower sheet fully extended, Figure 4 shows the upper sheet partially collected and the lower sheet fully extended, Figure 5 shows the upper sheet fully collected and the lower sheet fully extended, and Figure 6 shows the top sheet fully extended and the bottom fully retracted.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be seen in them, which comprises the parts and elements that are described in detail below.

Thus, as can be seen in said figures, the equipment in question essentially comprises a rotor (1) with spindle-shaped blades (2), like those of the Darrieus-type rotors (figure 1), or straight ones, like the of the Giromill-type rotors (figure 2), whose axis (3) is arranged horizontally, so that the rotor assembly is traversed at the front of the vehicle behind a central air intake grill (4) that also serves as protection.

This rotor (1) is linked to two current generators (5, 5 ') located on both sides of it and to which it is connected by means of a coupling (6) provided at each end of its shaft (3). The two current generators have ventilation grids (7) but have different characteristics, one being suitable for low speeds (5) and the other suitable for high speeds (5 '). In addition, the coupling (6) that links them to the rotor shaft (3) acts as a reducer or multiplier, and is electronically controlled to allow the connection of one or the other generator or both at the same time.

The equipment also has at least two folding blades, an upper one (8) and a lower one (9) arranged between the central grid (4) and the rotor (1) to regulate the opening and orientation of the hole through which passes the air that enters the rotor, which allows

generation of Energy.

These upper (8) and lower (9) sheets are electronically controlled, and to achieve their folding or extension, each sheet is formed from a plurality of slats that are folded over each other like a blind. Their different folding and extension positions and the effect they produce on the rotor can be seen in Figures 3 to 6.

Thus, with the two blades fully extended (figure 3), the air passage gap is smaller and, therefore, its speed increases, due to the Venturi effect, making the system more effective at low vehicle movement speeds.

The retracting of the upper (8) and lower (9) blades is greater or less (Figures 4 and 5), to adapt to the different speeds of the vehicle.

and when the vehicle speed is too high and can cause damage to the system, the upper sheet (8) is fully deployed and the lower sheet (9) retracts, causing the intake air to be diverted towards the lower part of the vehicle, not allowing it to enter directly into the rotor (1) (figure 6).

Ultimately, the upper (8) and lower (9) folding blades are configured in such a way that they are suitable to regulate the opening of the gap of

air passage, being able to adapt to the different

vehicle speeds or cause a Venturi effect,

and suitable for regulating the orientation of said hole

being able to make the air deviate and not be directed

remaining air from the underside of the vehicle.
