Description

POWER GENERATING DYNAMOELECTRIC DEVICE USED ON VEHICLES

Technical Field

The field of engineering covering the invention generally belongs to the field of mechanical engineering, more closely to the field of electric machines, and in particular, refers to a dynamoelectric device that converts reciprocating motion into rotary motion and that is used to generate electricity.

According to the International Patent Classification (I PC, 2018), the object of the invention is classified and marked with the basic classification symbol H02K 7/00, which defines Arrangements for handling mechanical energy structurally associated with dynamoelectric machines, as well as secondary classification symbols H02K 7/06, which denote the means for converting reciprocating into rotary motion or vice versa, and H02K 7/075 encompassing arrangements for handling mechanical energy using crankshafts or eccentrics.

Technical Problem

The technical problem solved by the invention concerned consists of the following: how to construct a device that allows the vehicle shock absorber up and down movement, which permanently occurs due to the movement of wheels on road bumps, to be converted into a rotary motion that transforms the kinetic energy of reciprocating motion into rotary motion energy that multiplies, and is then converted by the generator into electricity that is further used to recharge the battery, illuminate, supply the heating and cooling system, recharge drive batteries in electric vehicles etc. which would essentially convert the useless kinetic energy into useful electricity, generated in a way that takes place without environmental pollution and is cost-effective at the same time, as it does not require any kind of additional energy consumption other than the fuel required to drive the vehicle and, in addition, it is easy to generate, maintain, and incorporate on all kinds and types of vehicles.

Background Art

The automotive industry is one of the leading industries of the economy and nowadays life cannot be imagined without the use of cars, buses, trucks and other transport vehicles using internal combustion engines (ICE) whose basic driving raw materials are petroleum products and gas. Lately, we have been witnessing the growing use of electric cars with differently constructed electric drives, which, due to their ecological component, occupy an increasingly important place, especially in the countries particularly taking care of this ecological issue. For the time being, when deciding to switch to electric vehicles, the capacity of drive batteries is still an important limiting factor, so the greatest number of new innovative solutions addresses this issue.

It should also be noted that there are hydrogen-powered hybrid motors as well as vehicles with specially designed external surfaces with installed solar cells which allow the recharge of batteries, and here it should be borne in mind that this type of generating additional energy is conditioned by the time of day and weather conditions and is still quite expensive. In addition, there are different so far not implemented solutions with fans on the car roof or air flow tunnels through the car bodywork with turbines that run the alternators, but all this is designed more like an attempt of an individual, experimental way of solving the generating of additional electric power based on vehicle movement than a patent that could be applied to the serial application in the automotive industry.

In the patent application P-2015/0038 published on 30/06/2015 under the title "Electric generator with rotating stator", a device is provided which enables the generation of electricity without the construction of expensive and bulky hydroelectric power plants and wind farms with conventional wind turbines consisting of an electric generator housing, a rotating stator, a rotor, appropriate bearings of sliding metallic rings, carbon brushes with brackets and an appropriate gearbox. In this solution, the stator function has not been changed, but the stator character as a static part of the generator rotating in the direction opposite to the rotor is changed, thus achieving the amount of the induced current.

In the recognized patent 53798 B1 published on 30/06/2015, under the name "Machine for converting centrifugal force into mechanical and electrical energy", the presented device is intended for generating electricity primarily intended for driving road, air and cosmic means of transport, in which rotation of the electric motor rotor also leads to the rotation of eccentric flywheels, all of which are interconnected by a timing belt. When eccentric masses rotate, centrifugal forces acting on oscillators oscillating at an angle b are generated creating an alternating rotary motion that is transmitted to the input shaft of the rotary motion converter via the output shaft of the reducer and the second shaft. In the converter, the alternating rotary motion is converted into reciprocating, which is transmitted to the generator rotor by the PTO. This device can operate in any position as the total potential energy acting on rotating masses equals 0.

In the patent application P-2010/0058 published on 31/10/2011 under the title "System for converting rotation of rotary turbine into electricity", a device is provided which contains solutions for reducing mechanical losses that occur when increasing the number of rotations of slow rotating turbines using gearboxes, which is achieved by transmitting higher peripheral speeds of the turbine rotor directly through a gear system or high-viscous belts to the generator shaft, thereby avoiding mechanical losses generated by applying gearboxes box due to the interaction of a large number of gears.

The useful model CN 208272784 (U) published on 21/12/2018 shows a solution of a dual-vibration engine powered electric device comprising an engine body with a rotating shaft at which an active eccentric block is provided with a drive device with grooves for the sliding of movable pins that change their position depending on the vehicle inclination the amplitude of which may be smaller or larger. The vibrations generated in this way in the engine are transmitted through a rotating shaft connected to a generator that produces electricity which is then used in the engine for different purposes.

in the patent application CN 108631504 (A) published on 09/10/2018 under the title "Electricity production device", the device consists of a starter motor, a common engine, a generator, a gear, levers, an eccentric wheel, a flywheel, and a battery. The operation of this device is based on the fact that the starter motor starting gear is coupled to the ends of the arms of multiple groups of levers via joints connected with eccentric wheels linked to the drive mechanism, with counterweights with tensile spring on its short ends. The output shaft of the gearbox is connected to the input shaft of the generator via electromagnetic coupling. In addition to being complicated, such a device has a lot of gears with high friction force in its working set so the power of the generator is significantly reduced.

In the patent application US 2018241280 (Al) published on 23/08/2018 under the title "Vibration generation device and electronic device", a device for generating vibrations is provided consisting of a rotor designed to rotate along the rotation axis, which has a weight whose center of gravity is eccentric relative to the axis of rotation, thanks to the shaft inserted into the rotor to limit its movement in the radial direction and ensuring movement only in the axial direction, wherein this movement is connected with a mechanism that converts reciprocating motion into rotary motion, which is the purpose of this device as well.

Based on a careful examination of the state of engineering, it has been found that there are a large number of particularly Chinese applications dealing with the problem of converting rotary movement into reciprocating movement and vice versa, but the inventor herein concluded with surprise that there are no technical solutions relevant to the subject device. Summary of the Invention

The essence of the invention is a completely new structure of a dynamo-electric energy-generating device for use on vehicles which is designed to be made up of a housing, an assembly for converting the shock absorber reciprocating motion into the rotary motion of the generator transmission shafts, assemblies for increasing the number of rotations and assemblies for coupling the device with a generator for direct current or alternating current which is then used for recharging the battery, lighting, power supply of the heating and cooling devices or for recharging the electric vehicles batteries, thus converting the kinetic energy generated by stretching and contracting the shock absorber, which is constantly generated as a result of movement of vehicles over bumpy roads, and which otherwise remains completely unused, into useful electrical energy.

The essence of the invention is also that even on flat roads, the up and down movement of the shock absorber is approximately two centimeters each second, where this movement is carried out by the vehicle weight, which, depending on the type of vehicle, ranges from 1,000 to 10,000 kg, so that each wheel permanently exerts a 250 to 2,500 kg pressure on the shock absorber, which is a great force that easily ensures the operation of the subject device, so that the frictional forces that inevitably occur due to the rotation and interaction of the gears that enable the converting of the reciprocating motion in rotary motion, the multiplication of motion and transmission to the generator shaft, are negligible and do not affect the efficiency of electricity generation.

The essence of the invention is also reflected in the fact that the construction of the device in question is adaptable in size to different types of vehicles, thus making it easy to install and applicable not only to new vehicles but also to vehicles that are already in use, regardless of when they are produced.

The novelty of the invention also lies in that this device generates energy for the recharge of the battery, the heating and cooling of the vehicle, or other needs, thus eliminating the shortcoming reflected in that the power of the vehicle depends on the energy generated exclusively with the help of an alternator, which was particularly evident in the loss of power and increased fuel consumption in cases of using air conditioners, in particular when the vehicle is moving uphill.

The present invention has several advantages over the so far known technical solutions, the most important of which are as follows:

- the simplicity of the construction which enables a more efficient generation of electricity, which is then used for various purposes, for example, for increasing comfort, vehicle performances, etc. - longevity and high reliability in operation;

- simple installation, servicing, and maintenance;

- constructive adaptability to different types of vehicles regardless of their size, type, and purpose.

Detailed Description of the Invention

By observing the accompanying draft figures, it can be noticed that the essential part of the dynamoelectric device for generating additional electrical power on vehicles according to the present invention consists in: the housing 1 secured to a suitable chassis position and using a consistent coupler 94 coupled to the movable lever 95 of the shock absorber 25, the assembly 87 for converting the reciprocating motion of the shock absorber 25 into rotary motion, the assemblies 88, 89 for increasing the number of rotations and the assemblies 90, 91 for coupling the device with a generator for direct current or alternating current which it is then used to recharge the battery, illuminate, supply the heating and cooling devices, or recharge the electric vehicle batteries. The housing 1 can be made of different materials, it is adapted to the space, the shape of the bodywork and the places where the shock absorbers are fixed, and on the draft drawings given as proof of the invention feasibility, it is shaped as a hollow cuboid made most preferably of steel sheet, with rectangular sides that form the bottom 7, the front 3, the rear 4 and sides 5, 6 which are fitted, interconnected and fastened with screws so that they form a sealed chamber into which the mechanical oil is poured that lubricates the rotating parts of the above assemblies for the purpose of reducing friction.

By viewing Figures 1, 2, 5, and 6, it can be seen that the rectangular lid 2 is attached to the front 3, the rear 4 and the sides 5, 6, by means of the screws 47, wherein the joints are sealed in a common manner so that it is impermeable to moisture and mechanical impurities that are constantly present in the engine compartment due to often changes in temperature, atmospheric effects or as a consequence of vehicle movement over dusty, muddy and wet roads. From these figures, it can also be easily seen that on the lid 2 there is a larger circular opening 11 in which the one-way bearing 8 is inserted, through which the end of the rack 9, fastened to the bottom end of the shock absorber 25, is pulled, and a smaller also circular opening 72 for pouring and filling up of oil, closed with a plug 73. In one part of the rack 10, a threaded surface 12 is made coupled with the pinion 13, wedge 26- fixed to the narrowest part of the central shaft 14 whose central segment 15 is pulled through the bearing 16 inserted into the seat 17 made on the partition plate 18 positioned in parallel to the longer side of the housing 1. The lower free end of the rack 10 is first pulled through the linear bearing 85 fixed to the housing 29 by means of the screws 86 and then through the lip seal 28 and the opening on the bottom 41 side allowing vertical movement within the shock absorber 25 movement range, where the lip seal 28 has a sealing function, that is, prevents oil leakage. Changing or draining oil from the housing 29 is carried out by means of screwing the plug 32 fixed to the bottom 41. The other end of the central shaft 14 is pulled through the bearing 21, which is located on the rear of the housing 4 and is movably inserted into the cylindrical opening 20 hermetically sealed by the lid 23 by means of a screw 24. On the other side of the partition plate 18, the gear 22 is pulled on the central shaft 14 and attached and fixed with the wedge 27' inserted into the axial groove 27.

The assembly for increasing the number of rotations of the central shaft 14 consists of the gear 22 coupled using the pinions 33, 34 with the side shafts 37, 38 symmetrically spaced and parallel to the central shaft 14. The pinions 33, 34 are fixed with wedges 35', 36' inserted into the axial grooves 35, 36, of the shafts 37, 38 and connected to the bottom 7 in a way that their ends are pulled through the bearing 39, 40 located on the bottom 7 of the housing, with the openings 43, 44 being closed by the small lids 45, 46 using the screws 47. In this way it is possible to convert reciprocating motion formed by the movement of the shock absorber 25 up and down, using the rack 10, into the rotary motion of the central shaft 14. Bearing in mind that the average movement of the shock absorber 25 on flat and high-quality roads is approximately 2 cm every second, this means that the vehicle weighing 1000 to 10,000 kg exerts a 250-2500 kg pressure on each wheel, continuously doing the operation that, thanks to this device, turns from useless movement into a useful operation that generates electricity through the generator. In order to make better use of the thus obtained rotary motion of the central shaft 14, the gear 22 is connected to the pinions 33, 34 which rotate the shafts 37, 38 to which the gears 50, 51 are fixed using the wedges 48', 49' arranged in the axial grooves 48, 49, which gears are further pulled through the one-way bearings 52, 53 seated on the front panel 3, with the openings 54, 55 through which the ends of the shafts 37, 38 being closed with large lids 56, 57 and fastened with screws 66. In this way, by means of a coupling of the pinions 33, 34 at the lower ends of the shaft 37, 38 with the centrally-position gear 22, the number of rotations of the central shaft 14 is increased.

Through drive pinions 58, 59, by the wedges 75', 76' seated in the axial grooves 75, 76, the gears 50, 51 are fixed to the upper segments 77, 78 of the drive shafts 60, 61, whose upper ends are pulled through the bearings 62, 63 seated on the front plate 3, wherein the outer openings 81, 82 are hermetically sealed by the small lids 64, 65 by means of the screws 66. The other ends of the drive shafts 60, 61 are pulled through the one-way bearings 67, 68 mounted on the rear side 4 of the housing, and by means of wedges 83, 84 inserted into grooves 83', 84' the flywheels 69, 70 are fixed, through the articulated endings 71, 72 of which the universal joints 79, 80 are connected, which universal joints are linked to the generator (dynamo, or alternator), used to produce direct or alternating current. The one-way bearings 67, 68 are designed so that the bearing 67 rotates in the clockwise direction, while the bearing 68 rotates in the anticlockwise direction. In this way, the gears 50, 51 can alternately rotate when the shock absorber 25 moves down and up, so that the continuous operation of the drive shafts 60, 61 is ensured. The method of connecting and functioning of the articulated endings 71, 72 and the universal joints 79, 80 are well known in the state of engineering, so it is not separately shown and explained in more detail for the purpose of simplifying the description and the draft.

This construction of a dynamoelectric device for generating electricity on vehicles allows the work obtained by converting reciprocating into a rotary motion to be used for starting the generator 92 or the engine 93 of the compressor, the operation is which enables the generation of electricity and when the vehicle does not move, or in other cases which lead to the idling of the device in question. It should be emphasized that the conversion of reciprocating motion into rotary motion of the drive shaft connected with a generator for generating direct or alternating current can be realized in many ways, therefore, the constructive changes in the assemblies for obtaining rotary motion from reciprocating motion of the shock absorber, or the multiplier of the number of rotations, as well as the different construction of the assembly for coupling the drive shaft with the generator shaft, which are shown in the draft of the present invention, certainly do not come out of the scope of the protection of the subject invention by which reciprocating and useless motion of the shock absorbers, constantly present during the movement of the vehicle, is converted into useful work, that is, electricity, usable in different ways on all types of vehicles. Industrial and Other Invetion Methods of Use

The industrial production of the invention in question is possible in factories for making automotive equipment and even in well-equipped workshops for the production of electromechanical car parts.

The production of this device is easy to organize on the basis of technical documents which can be developed by experts in the subject field using the descriptions and drafts from this application.

The invention is suitable for serial production and applicable on all vehicles with a need for power consumption greater than that obtained using the existing alternators. It is noted that the application of the present invention is particularly suitable in cases of military vehicles (crawlers and other vehicles) which normally move on uneven terrains, which makes the effect of converting reciprocating motion into rotary motion particularly emphasized, so on that occasion a larger quantity of electricity is produced.

It is also necessary to emphasize that the device thus conceived allows permanent recharging of electric vehicle batteries, which significantly increases the range of movement. Moreover, which is also very important, this way of constant recharging of batteries achieves an increase in their durability.
