Description

Aerodynamic generator with bladed wheel for electric vehicles OBJECT OF THE INVENTION The invention, as the title of this descriptive document states, is an aerodynamic generator with a bladed wheel for electric vehicles. It is an innovation that offers advantages previously unknown within current technologies. TECHNICAL SECTOR The present invention falls within the sector of mechanics, lighting, heating, armament and blasting, in the subclass of liquid machines or engines, wind engines, spring engines, or weight engines, and the production of mechanical energy or propulsive thrust or reaction, not provided for elsewhere, especially in wind engines, specifically in wind engines with the axis of rotation arranged substantially parallel to the airflow entering the rotor that correspond to the classification of rotors. Similarly, it falls within the sector of diverse industrial techniques and transport, in the subclass of vehicles in general, in the classification of propulsion of electrically powered vehicles, particularly in the section of electric propulsion from energy extracted from the forces of nature, for example from the sun or wind, as well as in electric propulsion from energy external to the vehicle. STATE OF THE ART The present invention responds to the growing need to find sustainable alternatives for energy generation in the field of electric transport, especially given the challenge posed by the limited range of electric vehicles. In this context, one of the main obstacles identified is the exclusive dependence on external charging points, which can be impractical, costly and inefficient in situations of prolonged use or on long journeys. In everyday use situations, current electric vehicles must interrupt their operation to connect to charging stations, which can affect the user experience and limit the mass adoption of this technology. Although there have been significant advances in batteries and energy recovery systems, a comprehensive solution that allows for the effective use of available energy while the vehicle is in motion has not yet been achieved. Accordingly, this invention presents an aerodynamic generator using a bladed wheel for electric vehicles that allows the airflow generated during vehicle movement to be harnessed as a supplementary energy source. This solution aims to optimize the overall energy efficiency of the electric propulsion system, reducing dependence on external charging sources and contributing to more autonomous, efficient, and sustainable mobility. Currently, there is no known existence of any aerodynamic generator with a bladed wheel for electric vehicles that presents structural and constitutive technical characteristics equal or similar to those described in this descriptive report, as claimed. DESCRIPTION OF THE INVENTION The object of the present invention is the creation of an aerodynamic generator by means of a bladed wheel for electric vehicles that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany the present description. The invention relates to an aerodynamic bladed wheel generator for electric vehicles comprising a bladed wheel arranged on the outside of the vehicle and coupled to an electric motor rotor, which implies its operation as an electric generator, in combination with a partial cover housing or a front wind channel, allowing the transformation of the kinetic energy of the wind generated by the movement of the vehicle into electrical energy, in order to facilitate the auxiliary recharging of batteries in electric vehicles during their normal operation. This invention solves the problem of electric vehicles' exclusive dependence on external charging sources by proposing a system that generates energy while the vehicle is in motion, harnessing a constant resource: the frontal airflow. This reduces the need for frequent battery charging stops and improves overall energy efficiency without significantly altering the vehicle's normal operating dynamics. The aerodynamic generator is useful for electric vehicle users looking to extend their battery range with a supplementary energy generation system that integrates seamlessly into the vehicle's operation during normal driving. This contributes to more autonomous, efficient, and sustainable mobility, enhancing the user experience without requiring complex interventions or additional infrastructure. The wheel with blades has radially distributed vanes. These vanes are arranged in such a way that they receive the impact of the frontal wind generated by the vehicle's movement, thereby causing the wheel to rotate and facilitating the kinetic use of the airflow under real dynamic conditions. Furthermore, this bladed wheel is mechanically coupled to an electric motor rotor. This connection allows the rotational movement produced by the wind to be transferred to the motor, which, operating in reverse, acts as a generator, producing electricity without external intervention and using only the vehicle's movement as its power source. Furthermore, the invention includes a partial cover housing arranged around the bladed wheel. This housing is designed to allow the wind to impact only a specific area of ​​the wheel when its axis is perpendicular to the airflow, generating an unbalanced thrust that promotes its rotation. This feature optimizes the use of available airflow without the need for complex structures. In this case, this partial cover can be configured to cover approximately the lower or upper half of the bladed wheel. This specific arrangement aims to increase the system's efficiency by concentrating the wind's impact on a specific area that maximizes rotational momentum. Finally, the invention incorporates a front wind deflector located at the front of the vehicle, configured to direct airflow towards a specific area of ​​the wheel with blades. This deflector has a converging truncated conical shape, the outlet of which is oriented towards the top or bottom of the rotating element, accelerating the incoming airflow according to the principles of conservation of momentum. This geometric arrangement allows the flow to be concentrated over the active area of ​​the system, optimizing aerodynamic performance and the generation of electrical energy. To use the aerodynamic turbine generator for electric vehicles, the user must mount the system on the exterior of the vehicle and ensure it is properly connected to the corresponding electrical circuit. During movement, the airflow generated by the vehicle's motion impacts the turbine wheel, initiating the energy generation process without requiring any further intervention from the user. EXPLANATION OF THE FIGURES To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by some figures in which, for illustrative and non-limiting purposes, the following has been represented. Figure 1 illustrates the aerodynamic bladed wheel generator for electric vehicles with the partial cover casing.

The aerodynamic generator for electric vehicles comprises a bladed wheel (1) accessible from outside the vehicle and coupled to the rotor of an electric motor (2). This arrangement allows for the direct capture of the incident airflow during vehicle movement, transforming the kinetic energy of the wind into rotational mechanical energy, which is subsequently converted into electrical energy by the electric motor (2). The assembly incorporates a partial cover (3) or a front wind deflector (4), strategically positioned to direct the air towards the most efficient areas of the bladed wheel (1). The generated electrical energy is used for auxiliary charging of the vehicle's batteries during normal operation, contributing to improved range without interfering with the main propulsion system. The wheel with blades (1) is configured with blades distributed radially around its central axis. These blades are arranged so that they receive the impact of the frontal wind generated by the vehicle's movement, producing a continuous rotary motion. The radial arrangement of the blades ensures uniform utilization of the airflow, improving rotational stability and the aerodynamic efficiency of the system. The bladed wheel (1) is mechanically coupled to the rotor of the electric motor (2), either by its own shaft or with a transmission mechanism, which may include gears, so that the rotational movement of the wheel is transmitted to the rotor of the electric motor (2), immediately activating the generation of electrical energy. A direct connection eliminates unnecessary mechanical losses and ensures efficient energy conversion, while maintaining the structural simplicity of the assembly. Preferably, the generator comprises a partial cover casing (3) arranged around the bladed wheel (1). This casing is configured to allow the wind to impact only a specific area of ​​the wheel, generating an unbalanced thrust that promotes the start and maintenance of rotation. The casing also helps to reduce unused turbulence and channel the airflow towards the effective capture area. The partial cover casing (3) covers approximately the lower or upper half of the bladed wheel (1) in order to optimize wind harnessing efficiency. This arrangement allows for control of the direction and stability of rotation, minimizing counterproductive resistance and improving the overall performance of the generating system. In another preferred embodiment, the generator comprises a front wind deflector (4) installed at the front of the vehicle. This front wind deflector (4) is configured to redirect the airflow towards a specific section of the bladed wheel (1), concentrating the incident air and increasing its dynamic pressure before impact. The incorporation of the deflector increases the effective flow velocity over the active surface of the blades, improving the power generated without increasing the overall aerodynamic drag of the vehicle. Alternatively, the front wind channel (4) has a converging truncated cone shape, the outlet of which is oriented towards the top or bottom of the rotating element with radial blades (1), thereby accelerating the incoming airflow according to the principles of conservation of momentum. This geometric configuration ensures progressive air compression and greater efficiency in converting kinetic energy into rotational motion, enhancing the system's performance under normal vehicle operating conditions. Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
