[001 ] FIELD

[002] The present disclosure relates to the field of mechanical engineering.

Particularly, the present disclosure relates to the field of electric vehicles.

[003] DEFINITIONS

[004] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicate otherwise.

Driving wheel - Driving wheel refers to a wheel of a vehicle that is rotated by an electric motor and/or an internal combustion engine.

Driven wheel - Driven wheel refers to a wheel of a vehicle that rotates freely. More specifically, the driven wheel refers to a wheel of a vehicle which is not coupled to an electric motor and/or an internal combustion engine and rotates as a result of displacement of the vehicle.

[005] BACKGROUND

[006] Conventionally, most of vehicles are propelled by an internal combustion engines which use fossil fuels as a source of energy. The gases formed by combustion of the fossil fuels within the internal combustion engine are exhausted from such vehicles to the atmosphere. The exhaust gases pollute the air. Further, the exhaust gases increase global warming, imbalance rain distribution, and reduce agricultural production. In addition, the sources of fossil fuels are limited and are rapidly vanishing. Furthermore, more consumption of fossil fuels leads to more import of such fuels from other countries, thereby weakening the economy as a large amount of foreign currency is spent on the import.

[007] Presently, electric vehicles using electrical energy as a source of power are used as a substitute for the vehicles using fossil fuels. However, such electric vehicles are required to be equipped with batteries having a large capacity in order to propel the vehicle through large distances. The batteries of such vehicles are required to be charged periodically which is a cumbersome task. [008] Therefore, there is felt a need of a self power generating electric vehicle which alleviates abovementioned drawbacks of conventional electric vehicles.

[009] OBJECTS

[010] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:

[01 1 ] An object of the present disclosure is to provide a self power generating electric vehicle that is self-charging.

[012] Another object of the present disclosure is to provide a self power generating electric vehicle that does not use any fossil fuel for operation thereof.

[013] Yet another object of the present disclosure is to provide a self power generating electric vehicle which does not create air pollution.

[014] Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

[036] DETAILED DESCRIPTION

[037] A self power generating electric vehicle, of the present disclosure, will now be described with reference of the embodiments which do not limit the scope and ambit of the present disclosure.

[038] The self power generating electric vehicle comprises an electric motor, a charging unit, and at least one battery. The electric motor is configured to convert electrical energy into mechanical energy, in the form of torque. The torque generated by the electric motor is provided to a driving wheel of the electric vehicle, thereby displacing the electric vehicle. The electric vehicle comprises at least one driven wheel attached to it. The driven wheel is configured to be driven under an action of displacement of the vehicle. The charging unit is coupled to the at least driven wheel of the electric vehicle. The driven wheel, to which the charging unit is coupled, provides torque to the charging unit while rotating. The charging unit is adapted to receive the torque from the driven wheel and convert the torque into electrical energy. [039] In an embodiment, the charging unit is selected from the group consisting of an alternator, a dynamo, a generator, and other charging devices. In a preferred embodiment, the charging unit is an alternator.

[040] However, the charging unit is not limited to an alternator, a dynamo, a generator, and other charging devices. Any charging unit, which is an electric power generating unit, or the charging unit, which may be hereafter developed in the art, is well within the scope and ambit of the present disclosure.

[041 ] The charging unit converts received torque into electrical energy. The electrical energy is provided to the battery or may be directly provided to the electric motor. The electrical energy received from the charging unit is stored in the battery. Further, the battery is electrically coupled with the electric motor via a plurality of wires. The battery supplies the electrical energy to the electric motor. The electric motor converts electrical energy received from the battery into mechanical energy, in the form of torque, which is further supplied to the at least one driving wheel of the self power generating electric vehicle.

[042] The electrical energy produced by the charging unit can be also directly provided to the electric motor of the self power generating electric vehicle.

[043] In an embodiment, the battery is selected from a group consisting of lead acid battery, lithium-ion battery, nickel-cadmium battery, and nickel metal hydride battery. However, any battery, which is a type of electrical storage unit, is well within the scope and ambit of the present disclosure.

[044] In an embodiment, the self power generating electric vehicle further comprises a solar powered charging unit and a speed controller. The solar powered charging unit is used as an additional power source. The solar powered charging unit is electrically coupled with the battery. The solar powered charging unit includes a plurality of solar panels which generates electric current when solar energy is incident thereupon. [045] The speed controller controls torque output of the electric motor, thereby controlling the speed of the self power generating electric vehicle.

[046] In an embodiment, the charging unit is disposed proximal to the driven wheel of the self power generating electric vehicle. In another embodiment, the charging unit is disposed within the driven wheel of the self power generating electric vehicle. In yet another embodiment, the charging unit is coupled to an axle of the self power generating electric vehicle. In still another embodiment, the charging unit is disposed within a hub of the self power generating electric vehicle.

[047] The self power generating electric vehicle, of the present disclosure, is now described with reference to figure 1 through figure 10.

[048] Figure 1 illustrates a side view of a self power generating electric vehicle 101 , in accordance with an embodiment of the present embodiment, depicting installation of an alternator 108 coupled to a driven wheel 1 13 via a belt drive 1 18.

[049] The self power generating electric vehicle 101 is basically a two-wheeled vehicle. An electric motor 109 is operatively connected to a gearbox 1 1 1 . Further, the gearbox 1 1 1 is operatively connected to a driving wheel 1 12. The self power generating electric vehicle 101 includes the alternator 108 which is the charging unit. In an embodiment, the charging unit is a dynamo, a generator or any other charging devices.

[050] The alternator 108 is disposed proximal to the driven wheel 1 13. The alternator pulley 1 14 is attached to the alternator 108, and is coupled to a driven wheel pulley 1 15 of the driven wheel 1 13. In an embodiment, the alternator pulley 1 14 is coupled to the driven wheel 1 13 via the belt drive 1 18. In another embodiment, the alternator pulley 1 14 is coupled to the driven wheel 1 13 via a chain drive (not shown in figures), or a gear drive (not shown in figure).

[051 ] The alternator 108 is configured to convert torque provided by the driven wheel 1 13 into electrical energy. The alternator 108 is electrically coupled with a battery 1 10 which receives electrical energy from the alternator 108. The battery 1 10 is configured to supply the electrical energy to operate the electric motor 109. The electrical energy is supplied by the battery 1 10 to the electric motor 109 via a plurality of wires 121 . A speed controller 1 16 is installed to control the speed of the electric motor 109. A solar powered charging unit 1 17 is installed as an additional power source for charging the battery 1 10.

[052] In an operative configuration, a shaft of the electric motor 109 starts rotating by using the electrical energy supplied by the battery 1 10. The torque generated by the rotations of the shaft of the electric motor 109 is transferred to the driving wheel 1 12 via the gearbox 1 1 1 . The rotation of the driving wheel 1 12 leads to the rotation of the driven wheel 1 13. The driven wheel pulley 1 15 starts to rotate with the driven wheel 1 13. The driven wheel pulley 1 15 transfers torque to an alternator pulley 1 14 of the alternator 108 via the belt drive 1 18, thereby rotating the shaft of the alternator 108. The rotation of the shaft of the alternator 108 generates electrical energy. The generated electrical energy is stored in the battery 1 10. The battery 1 10 supplies stored electrical energy to the electric motor 109. The electric motor converts the electrical energy into mechanical energy in the form of torque which is supplied to the driving wheel 1 12 in order to propel the self power generating electric vehicle 101 .

[053] The solar powered charging unit 1 17 is mounted on a connecting structure that is coupled to a frame of the self power generating electric vehicle 101 . The solar powered charging unit 1 17 provides additional electrical energy to the battery 1 10.

[054] Figure 2a illustrates another way of coupling the alternator 108 to the driven wheel 1 13 of the self power generating electric vehicle 101 . Figure 2b illustrates a front view of the alternator 108 coupled to the driven wheel pulley 1 15 of the self power generating electric vehicle 101 of figure 2a. Figure 2c illustrates an isometric view of the alternator 108 coupled to the driven wheel pulley 1 15 of the self power generating electric vehicle 101 of figure 2a. [055] As shown in figure 2a, 2b, and 2c, the driven wheel pulley 1 15 is mounted within the driven wheel 1 13. The alternator pulley 1 14 is attached to the alternator 108. The alternator pulley 1 14 is coupled to the driven wheel pulley 1 15 via the belt drive 1 18.

[056] Figure 3 illustrates yet another way of coupling the alternator 108 to the driven wheel 1 13 of the self power generating electric vehicle 101 . The alternator 108 is installed within the driven wheel 1 13. The alternator 108 is configured to rotate along with the driven wheel 1 13.

[057] Figure 4 illustrates an isometric view of a self power generating electric vehicle 100a, in accordance with another embodiment of the present disclosure, depicting installation of an alternator coupled to a driven wheel via a belt drive.

[058] The self power generating electric vehicle 100a is basically a four-wheeled vehicle. The self power generating electric vehicle 100a includes two alternators 108 disposed at the driven wheels 1 13 as shown in figure 4. The two alternators 108 are coupled to the driven wheel pulley 1 15 of the driven wheels 1 13 by using the belt drive 1 18. The two alternators 108 are electrically coupled to the battery 1 10 (not shown in figure 4) which is further electrically coupled to the electric motor 109. The electric motor 109 is coupled to the gearbox 1 1 1 which is further operatively coupled to the driving wheels 1 12 via a connecting shaft. The solar powered charging unit 1 17 is disposed on the roof and at an operative front surface of the self power generating electric vehicle 100a as an additional power source for charging the battery 1 10.

[059] In an operative configuration, the battery 1 10 supplies electrical energy to the electric motor 109. The electric motor 109 facilitates the rotation of the driving wheels 1 12 via the gearbox 1 1 1 . The driven wheels 1 13 rotate under the influence of the propulsion provided by the driving wheels 1 12. Further, the driven wheel pulley 1 15 of the driven wheels 1 13 rotates with the driven wheels 1 13. The alternator pulley 1 14, which is coupled with the driven wheel pulley 1 15, starts rotating along with the driven wheel pulley 1 15. Thus, the alternator 108 generates electrical energy which is stored in the batteries 1 10. The electrical energy is then provided to the electric motor 109 by the battery 1 10, thus completing the cycle.

[060] Figure 5 illustrates an isometric view of the self power generating electric vehicle 100a, of figure 4, depicting another way of coupling the alternator 108 to an additional driven wheel 1 13a.

[061 ] The alternator 108 is coupled with the additional driven wheel 1 13a of the self power generating electric vehicle 100a. The additional driven wheel 1 13a has two driven wheel pulleys 1 15. The two alternators 108 are coupled to the driven wheel pulleys 1 15 via the belt drive 1 18.

[062] Figure 6 illustrates an isometric view of a trolley 103 for the self power generating electric vehicle of the present disclosure.

[063] The trolley 103 has a plurality of driven wheels 1 13. In an embodiment, the trolley 103 has four driven wheels 1 13. The alternator pulleys 1 14 of the alternators 108 are attached to each driven wheel pulley 1 15 of the driven wheels 1 13 via the belt drive 1 18. In the trolley 103, the number of the alternators 108, which are operatively coupled to each driven wheel 1 13, may be one or more than one. In an embodiment, the trolley 103 includes a battery (not shown in figure 6). The alternators 108 are electrically coupled to the battery which is further electrically coupled to the electric motor.

[064] The trolley 103 includes a suspension 1 19 disposed on a frame thereof. In an embodiment, the suspension 1 19 includes a plurality of springs. The trolley further includes an attachment bracket 120 disposed on the suspension 1 19 to facilitate the attachment of the trolley 103 with any vehicle. The trolley 103 is attached to any vehicle at an operative bottom side or back side of the vehicle.

[065] The trolley 103 is attached to any vehicle such that the driven wheels 1 13 of the trolley 103 rotate with the driving wheels 1 12 of the vehicle.

[066] Figure 7 illustrates an isometric view of the trolley 103, of figure 6, attached to a self power generating electric vehicle 100b of the present disclosure. In an embodiment, the self power generating electric vehicle 100b is a multi-axle vehicle.

[067] The trolley 103 is attached to the self power generating electric vehicle 100b such that the driven wheels 1 13 of the trolley 103 rotate with the driving wheels 1 12 of the self power generating electric vehicle 100b. The solar powered charging unit 1 17 is installed at an operative top surface of the self power generating electric vehicle 100b as an additional power source generating electrical energy.

[068] Figure 8 illustrates a back view of a self power generating electric train bogie 122, in accordance with yet another embodiment of the present disclosure. The alternator 108 is coupled with the driven wheel pulley 1 15 which is attached to the driven wheels 1 13 of the self power generating electric train bogie 122. The alternator 108 is coupled with the driven wheel pulley 1 15 via the belt drive 1 18. When an engine of the self power generating electric train 102 drags a train bogie 122, the driven wheels 1 13 of the train bogie 122 start rotating, which further rotates the driven wheel pulleys 1 15. The rotation of the driven wheel pulleys 1 15 of the driven wheel 1 13 provides torque to the alternator 108 and the alternator 108 generates electrical energy using the torque. The generated electrical energy is provided to the engine of the electric train 102. The generated electrical energy is stored in the batteries 1 10. In an embodiment, the generated electrical energy is directly supplied to the electric motor of self power generating electric train 102 instead of storing the same in the batteries. In the case of self power generating electric train 102, the excess electrical energy generated by the charging unit can be used directly without storage for other consumption purposes.

[069] Figure 9 illustrates an isometric view of a bogie wheel assembly of the self power generating electric train bogie 122 of figure 8. The alternator 108 is coupled with the driven wheel pulley 1 15 that is attached to the driven wheels 1 13 of the self power generating electric train bogie 122. The figure 9 illustrates exact location of the driven wheel pulley 1 15 of the driven wheel 1 13, and the alternator 108 of the bogie wheel assembly in the self power generating electric train bogie 122. [070] Figure 10 illustrates a front view of the gearbox 1 1 1 of the self power generating electric vehicle of the present disclosure.

[071 ] The gearbox 1 1 1 includes a variator 126 and a clutch component 124. The variator 126 is coupled with the electric motor 109. The variator 126 is operatively coupled to the clutch component 124 via a belt drive 130. The variator 126 receives the input torque from the electric motor. The transmission ratio between the variator 126 and the clutch component 124 is adjusted by its internal mechanism.

[072] In an embodiment, the gearbox 1 1 1 is an automatic gearbox that can be used for motorbikes and three-wheeled vehicles.

[073] The present disclosure is also applied to the alteration or modification of all types of old vehicles. The alternator 108, electric motor 109, speed controller 1 16, and batteries 1 10 are the main components to modify or alter the old vehicles into self power generating electric vehicle 100.

[074] The self power generating electric vehicle, of the present disclosure, is a self- charging vehicle as the battery gets charged by the alternator while the electric vehicle is in motion. Further, the self power generating electric vehicle of the present disclosure has no fossil fuel consumption, thereby not creating any air pollution.
