    ELECTRICAL ENERGY GENERATION EQUIPMENT FOR VEHICLES WITH
    COLD UNIT
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The present invention is framed in the technical field of electricity generators. More specifically, an electric power generation equipment for vehicles is described. It allows to obtain electrical energy to power a unit of cold of the vehicle from the movement of rotation of the tires of said vehicle.
    BACKGROUND OF THE INVENTION
    At present, the use of vehicles comprising cold units for the transport of goods that have to be refrigerated is very common. Generally these types of cold units are powered by electrical energy obtained with diesel engines. The most important technical problem associated with the use of diesel engines for this purpose is that they consume a lot and are very polluting.
    Some alternative solutions are known from the state of the art for obtaining electrical energy for use in said cold units. Some of the solutions involve obtaining said energy by taking advantage of the movement of the vehicle itself.
    In this sense, for example, electric power generation devices are known which comprise at least one wheel that travels on the ground when the vehicle is moved and that is connected to an electric power generator to obtain such electricity, for example in the document CN103434396. In this device the movement of the wheel to the ground is done by means of a hydraulic piston and the movement of the wheel is transmitted to a motor by means of a gear system.
    It is also known document CN201009746 that allows generating electricity

    by means of a dynamo installed in the axle of the vehicle and which is connected to a gear system that links it to a vehicle wheel.
    However, these described solutions still do not solve an essential technical problem, which is to maintain the electric power in the cold unit during periods when the vehicle is stationary, especially when it is stationary for a long time. As previously described, the known devices allow to obtain energy during the periods of movement of the vehicle, however there are no solutions proposed that allow to maintain a correct supply of electrical energy when the vehicle is stationary.
    This is a major disadvantage at times when the vehicle is not rolling but it is necessary to maintain the temperature in the cold unit. For example, in cases where the vehicle is traveling on a road that closes and the vehicle is trapped without access to alternative energy sources. In these cases, as the vehicle is stationary, the electrical energy necessary to keep the cold unit running is not generated and the merchandise being transported can be damaged.
    DESCRIPTION OF THE INVENTION
    The present invention proposes an electric power generation equipment for vehicles with a cold unit that allows to solve the problems of the state of the art previously described.
    Fundamentally the present invention allows to generate energy by the rotational movement of the tires of the vehicle, using a wheel, preferably of rubber and of smaller size than the tires of the vehicle, and resistant. Said wheel comes into contact with one of the tires of the moving vehicle, at the top of it.
    The rotation of the wheel caused by the rotation of the tire makes a power generator act to which it is coupled by a shaft. In an exemplary embodiment of the
    5

    invention, with a constant vehicle speed of more than 90 km / h, the ratio designed for the manufacture of the wheel provides approximately 3000 rpm to the generator. In this way an energy of 400 V-V is produced. The energy generated is collected, distributed and stored in at least one solid battery (preferably lithium or graphene but which could be of any material known or developed in the future and that allows to improve the performance of the batteries). In this way, when there is an excess of energy produced, it is not lost or disposed of, but is stored in case it has to be used later, for example if the vehicle is stationary but the cold unit must be kept running.
    A control unit configured to receive a plurality of external signals, for example one of the vehicle speed, is part of the invention, and with these signals manages the functionality of the equipment elements. In the case of the signal that determines the speed of the vehicle, depending on whether the speed is sufficient or not, the pneumatic mechanisms are activated, in the case of the active speed or not a drive mechanism to bring the wheel into contact with The tire for energy.
    The control unit also manages the energy needs of the cold unit and can also be connected to the semi-trailer lighting system. It is also responsible for the distribution of stored energy or the energy that is being generated. With this control unit the equipment of the invention has a great capacity to expand with more control and communication peripherals that can help to more efficiently manage the stored energy or the energy that is being generated.
    In an exemplary embodiment, the control unit can take into account routes, stops, travel times and speed to generate automatic behavior of the equipment.
    The contact between the wheel of the equipment and the tire of the moving vehicle is controlled by a drive mechanism with an electric and electro-pneumatic impulse until the electric generator is at 100% capacity. At this time the wheel is moved to remove the contact (electrically or pneumatically) and the rubber wheel goes to a rest position. The drive mechanism preferably comprises withdrawal springs. This way the level is controlled
    5
    10
    fifteen

    30
    of load of the electric generator and therefore the deployment or withdrawal of the contact wheel (rest position or working position) according to the level of load.
    Thus, with the equipment of the present invention, energy is generated to power the vehicle's cold unit by friction and rotation by feeding electric motors charged, in this case, to generate the necessary cold.
    Preferably, the equipment is used to start electric motors installed in the vehicle, which in turn are responsible for refrigeration and storage of goods such as food. In an exemplary embodiment the equipment is used in refrigerated trucks or semi-trailers. As previously described, the equipment can also be used for, with the energy generated, the electrical components required in the semi-trailer of the vehicle, such as those of the lighting system.
    The energy used for this cooling purpose is produced with the equipment of the present invention in a totally ecological, noise-free manner. It also allows, for example, to replace current agricultural diesel engines that are currently used in bulk and that are tremendously polluting for the fuel they use and for the noise they emit when they are running.
    Another advantage of the equipment of the invention is that it can be oriented at different angles to perfectly fit the different types of axles of each existing vehicle. So it is a universal team that adapts to any truck or trailer model. Likewise, the drive mechanism can be controlled electrically and / or pneumatically according to the needs of each application.
    In addition, the equipment joins the vehicle in “neutral” areas of the vehicle, away from sensitive points such as brakes, suspensions, etc. and therefore does not compromise the factory specifications of the vehicle. In an embodiment of the invention it could be an adaptation to it. The team is also not in contact with critical areas such as the tires of the tires of the vehicle or on the axle of the vehicle, which is where the brakes are and therefore more temperature is taken. This avoids possible risks of equipment fire or malfunction.

    The proposed equipment can also be used in reefer containers that are used in all ports of the world to transport cold goods (at a low temperature). The equipment can be connected in this type of containers by contacting the wheel with the tires of the trailers that are used to move them, to keep the cold unit of these containers active without consuming diesel and in a silent and ecological way with a very autonomy prolonged
    Until now, reefer containers are connected directly to external power lines when they are in port or on the ship in which they are transported. In this way, the present invention would provide a solution to the cold unit's energy requirement during transport. In this way, the weight of the containers is also reduced since the diesel generator that is usually coupled to said additional energy generation can be eliminated.
    Also part of the invention is an equipment that additionally comprises a gasoline combustion engine. In one example, the equipment comprises a mechanical system of combination of electrical and combustion elements for the generation of kinetic energy that moves a mechanical compressor of the vehicle's cold unit and generates electrical energy to power the rest of the electrical components. In this case, the equipment comprises a type of transmission of a planetary transaxle in which both electric and combustion engines act to give traction to the compressor.
    The invention also contemplates the possible connection of the equipment to any external power source. For this, it comprises a three-phase connection, which is preferably arranged at the rear of the vehicle trailer so that it can be connected to any conventional three-phase 380-400V electrical network so that it can be used both to power the cold unit, such as To charge the batteries.
    In another exemplary embodiment in which the equipment also comprises a combustion engine. In this way the team has greater autonomy for the moments in which the vehicle has been standing for a long time and the solid graphene battery is discharged. It is a small combustion engine, with low consumption

    of fuel and operation management combined with the battery.
    Finally, it should be noted that indirectly the invention considerably improves the distribution of the weight of the semi-trailer of the vehicle in which it is installed since it distributes the weight evenly on the underside of said vehicle instead of only increasing it at one end of the vehicle as It happened before with diesel engines that served as power supply. It also provides extra rigidity to the chassis of the vehicle since the batteries are installed in said chassis.

    An example of embodiment of the present invention is described below with the aid of Figures 1 to 4.
    The present invention describes an electric power equipment for vehicles that have a cold unit. The described equipment can be seen for example in Figure 1 and comprises a connection intended to be connected to a cold unit of a vehicle.
    The equipment comprises a shaft (1) and a wheel (2) arranged at one end of the shaft (1), and said wheel (2) is intended to contact the top of one of the tires (3) of the vehicle such that when the vehicle moves it causes a rotational movement of the wheel (2) and therefore of the axle (1).
    Figure 2 shows a side view of a vehicle with a cold unit in which equipment such as the one described has been installed. In this figure you can see how the wheel (2) of the equipment is in contact with one of the tires (3) of the vehicle when it is in working position, that is, when it is generating energy.
    In figure 3 you can see the equipment installed in a vehicle with a cold unit from a different view. In this case a rear view of the vehicle has been represented and the area of the chassis in which the equipment is installed can be seen.
    The equipment also comprises an electric generator (4) connected to the shaft (1) that converts the rotation energy (1) of said shaft (1) into electricity and which comprises the connection. It also has a solid graphene or lithium battery, linked to the electric generator (4) to store the electricity generated by the rotation of the tree (1).
    To move the wheel (2) between a resting position in which it is separated from the tire (3) and a working position in which it is in contact with the tire (3) the equipment comprises a drive mechanism.
    Said drive mechanism comprises a plate (5) with detachable attachment means for attachment to the lower part of the vehicle chassis and with the possibility of tilting with respect to an axis of rotation (9); a pneumatic mattress (6) attached to the plate (5) and
    5
    10

    30
    attached to a fixed element (10) such that, when inflated, the plate (5) tilts with respect to the fixed element (10) around the axis of rotation (9) to move the wheel (2) from the rest position (figure 4a) to the working position (figure 4b); and a solenoid valve that allows the passage of pressurized air to the pneumatic mattress (6) or the air outlet inside the pneumatic mattress (6) for inflation or deflation.
    Likewise, the equipment has a clamping set comprising a cover (7) that supports the electric generator (4) and a grip (8) configured to join the plate (5). These elements can be seen in the exploded view of Figure 1. The electric generator (4) is housed inside the cover (7).
    It also has an internal combustion engine that can be connected to the cold unit of the vehicle configured to supply electric power to said cold unit when the battery is discharged.
    The equipment includes a control unit, which is an essential part of its management and operation. The control unit is at least connected to the electric generator, the battery and the drive mechanism.
    This control unit receives signals from the different components and also sends and drives electrically and pneumatically others for movement, connection and disconnection. The control unit is also configured to receive data on the battery charge, energy demand, power generation and the speed of the truck. Depending on the data obtained from each element of the equipment, the control unit manages the activation of the pneumatic mechanisms to bring the equipment wheel into contact with the vehicle's tire. Likewise, the control unit determines if the power generation is being carried out correctly.
    In exemplary embodiments, this control unit can be additionally connected to other external devices such as displays of the equipment as a whole, or additional control devices for power generation management and charging and discharging of the equipment's batteries.
    In the internal combustion generator that is used for eventual cases of a prolonged stop of the vehicle is where, in an exemplary embodiment, a flywheel is located to increase the operating efficiency of said internal combustion generator. This flywheel makes it possible to provide the combustion engine 5 with greater torque to generate sufficient autonomy energy with a gasoline engine as small as possible, balancing consumption to a minimum.
    This exemplary embodiment is only used at specific times when, due to prolonged stops, an additional energy supply is necessary. It is anticipated that with the development of more efficient polymers and materials for batteries, it is not necessary to use the internal combustion generator in the equipment under any circumstances.
    In a vehicle you can install as many equipment as there are tires. The number of 15 devices will depend primarily on the amount of energy needed to run the vehicle's cold unit.
