    BACKGROUND OF THE INVENTION

    Currently in the market there are fixed windshields that can be attached to motorcycles, most of these windshields are fixed by screws and fasteners fixed to the vehicle. There are also adjustable or variable-mount windshields, but with different systems than shown in this patent and that do not reflect the possibility of the windshield being hidden.
    There are windshields for motorcycles adjustable in height by mechanical means, through manual adjustments of the screws that fix the position of the windshield. This is how 30 windshields are known for motorcycles that fit various
    sizes and models for fixing on various types of handlebars and in turn allow the rear view mirror rods to pass through the windshield. There are also motorcycle windshields that can be quickly mounted and disassembled from the vehicle, preferably without using tools.
    The patent ES 2 122 355 T3 describes a device for adjusting a windshield that adjusts its inclination using two handlebars forming a joint square. Guide handlebars raise or lower the windshield.
    The ES 2 362 189 T3 patent consists of a mounting structure in which an angle can be changed into a simple structure. The structure including a first support suitable for mounting on the front portion of a vehicle body, a windshield mounted on the first support and a second support arranged between the windshield.
    The EP2088066B1 patent consists of a windshield that has a mechanism for regulating the operating angle. A deflector plate inclined towards the rear direction of the vehicle body is arranged between the fairing and covers a front upper portion of the vehicle body, the angle of deflection of the deflector plate being adjustable.
    The patent EN 2 323 921 A1 is made up of two guides made of sturdy metal on which the windshield visor slides to a stop, which, according to the pressure of the air generated by the advance of the motorcycle, pushes the visor upwards through 20 the guides, anchored through suitable means of union that support them to the fairing. This system divides the windshield into two parts and is only capable of regulating the height of the windshield in a limited way and without being able to hide it.
    Patent ES 2 384 407 T3 refers to an improvement of a windshield that is mounted on an upper portion of a fairing that covers an upper front portion of a vehicle body vertically movable. It proposes a motorcycle including a windshield structure mounted on an upper portion of a fairing that covers an upper front portion of a vertically movable vehicle body, a left lane and a right lane that are fixed to a vehicle body side and They extend in a vertical direction. 30
    In all cases the system used is totally different from the one used here.
    patent, different types of mechanisms are used for displacement and the windshield cannot be hidden. Therefore, no windshield with the system set forth in this patent or windshield that can be hidden in the front fairing have been found by the author.

    EXPLANATION OF THE INVENTION

    The windshield's function is to protect, providing the pilot with the necessary protection against inclement weather and greatly increasing aerodynamics.
    The system consists of a windshield that can be moved by a mechanism 10 driven by an electric motor. The windshield is hidden in the inner part of the front fairing, where it is not visible and moves when the user wishes it to an operating position to which it arrives after a displacement.
    The general operation of the system consists of a small electric motor connected to the current of the vehicle that is responsible for driving a mechanism (further on the possible mechanisms that can be used will be explained below), which causes the windshield movement to which it goes in solidarity. United. The windshield is located inside the front fairing and slides between two vertical guides and a support with horizontal opening located at the top, this support is responsible for correctly holding the windshield and prevent it from moving by force action 20 aerodynamics, in addition to having a non-reversible or self-locking system in the mechanism responsible for transmitting the movement. There are two limit switches located on the lower and upper stop that are responsible for stopping the movement of the engine when it reaches extreme positions.
    Figure 1 shows the front of a “naked” type motorcycle with the windshield 25 hidden, and in figure 2 the same front is shown with the windshield driven.
    The system is operated from the control panel of the vehicle, which can cause the windshield to rise or fall, and allows the windshield to be driven (windshield raised to protect from the air) or without it (hidden windshield). The system can be operated at any time, even when the vehicle is running. It has 30 multiple positions between the bottom stop and the top stop. Depending on the time that
    the user presses the button, the windshield will rise or fall proportionally. A sequential system similar to that of the car windows can also be incorporated, that is, with a short touch it goes up or down as much as possible and with longer presses it can be moved to intermediate positions. Therefore, the system can be adapted taking into account the height of the driver, the adjustable height of the seat or the speed of travel.
    This type of system can be incorporated into motorcycles or other types of vehicles, but it must be taken into account that in order for a hidden windshield to exist, there must be a front fairing where it can be hidden. It can also be used without the need to hide the windshield, and the same can be totally or partially visible, even if it is not the main idea of the patent.
    On motorcycles that do not have windshields when driving at a high speed, that is, by highway or highway, a large amount of index air flow directly over the rider, causing the ride to not be as comfortable as it should. Some types of motorcycles, such as Naked motorcycles, do not usually incorporate windshields because, in general, the aesthetics of the motorcycle worsens. With this system it is possible to maintain the aesthetics of the motorcycle (the windshield can be hidden) and also provide the maximum possible comfort. Therefore, in an urban section you can go without the windshield and when you enter a faster interurban route you can drive with the windshield activated. In this way, the comfort of motorcycles is improved, without losing their personality and aesthetics. The system can also be used on motorcycles where aesthetics is not so important but if comfort, for example on scooter motorcycles, the system can be used to adjust the windshield height simply and efficiently. 25
    There is the possibility of automating the windshield movement process. One possibility is to add a programmed mode of operation, so that depending on the speed of the vehicle the position of the windshield varies automatically (at higher speeds, higher windshield height and therefore more aerodynamic protection). This operation could be carried out from the control unit connected to the displacement mechanism, using an algorithm that relates the speed of the vehicle to the height of the windshield. A system can also be incorporated which, through a small opening in the fairing, uses the air flow that hits the vehicle
    so that it winds up the windshield using a plunger. Depending on the diameter of the piston, the geometry of the opening and the weight of the windshield, such a system could be designed.
    It must be taken into account that a closed cabin can be created where the windshield was placed inside the fairing, in this way dirt entry is avoided and a safer and cleaner system is achieved.
    This system can be used for a completely vertical windshield displacement or can be made at an angle depending on the required geometry, for this it is enough to modify the geometry of the guides where the windshield is housed.
    As a safety measure, an overload protection device can be used, which automatically switches it off if excessive resistance to the movement of the crystals occurs.

    PREFERRED EMBODIMENT OF THE INVENTION

    In this section a more detailed explanation of the system will be made. First, different mechanisms that allow the movement of the windshield will be described, then a complete description of the system will be made by choosing one of the mechanisms 5 possible for its movement.
    As already indicated, the windshield movement is necessary, for this purpose different mechanisms can be used:
    - Pinion-rack mechanism (Figure 3): it consists of a gear (1) that is moved by an electric motor and that transmits its circular movement to a toothed rack (2), transforming the movement into a linear one. Depending on the direction of rotation of the motor, the windshield (3) rises or falls.
    - Pinion-chain mechanism (Figure 4): the system consists of a gear (4) with circular movement that is moved by a motor. This gear rotates and transmits the movement to a chain (5) located between two fixed axes (6) that 15 has the windshield support (7) attached to it, causing its linear movement within the guides. Depending on the direction of rotation of the motor, the windshield rises or falls.
    - Rigid cable mechanisms - guides (Figure 5): an electric motor moves a circular gear (8) that is connected with a rigid cable (9). At one of the 20 ends of the rigid cable is attached the windshield support (10) which in turn is held by vertical guides (11). Depending on the direction of rotation of the motor, the windshield (12) ascends or descends, pushing or pulling the cable. A similar system is currently used in some electric windows of cars. 25
    - Traction cable mechanisms - guides (Figure 6): an electric motor (13) drives an endless wheel-screw assembly (14) where there is a drum in which there is a coiled cable. The cable has two ends (15) designed so that with one turn one end is wound and the other is unwound, one of these cables is attached at the top of the windshield holder and another at the bottom. Depending on the direction of rotation of the motor (15), one cable or the other is pulled and the windshield (16) is raised or lowered through the
    guides (17). In the guide rail there is a sliding piece (18), in which the windshield is attached. A similar system is currently used in some electric windows of cars.
    - Mechanisms Cam-follower (Figure 7): an electric motor (19) rotates a cylinder (20) where there is a slit (21) and a follower (22) is placed, which in turn is jointly connected to vertical guides (2. 3). When the cylinder rotates, the tracker moves linearly vertically. Depending on the direction of rotation of the motor, the windshield rises or falls.
    - Mechanism of articulated arms (Figure 8): the electric motor assembly gives movement to a toothed sector (24) by means of a gear (25) that is integral with the articulated arms (26), whose ends are housed in a support (27) in which the windshield (28) is located, in this way, the rotational movement of the electric motor in one direction or another results in a movement up or down the windshield of the door.
    - Swinging mechanism (Figure 9): a mechanism rotating within a rectangle transforms the circular movement into a linear movement of the windshield.

    In all the mechanisms used an electric motor is used as it is the fastest and most comfortable way of operation, but all of them could work if necessary manually. It is also necessary to block the windshield, so that it does not move by itself due to the aerodynamic force during travel, for this purpose self-locking mechanisms can be used, leaving the windshield securely held.
    Once the possible mechanisms have been explained, the operation of the complete system will be explained in more detail. In this explanation the mechanism used is that of traction cable, if another mechanism was used, it would only change the system used to move the windshield and the necessary fixings.
    Figure 10 shows a steering column of a motorcycle with no added elements. You can see the brake levers (29), the handlebars (30), the 30 control panel (31), the lateral (32) and central steering columns (33) and the
    joints between columns (34). This part of the motorcycle structure is where the mobile windshield lift system will be located.
    Figures 11 and 12 represent the mobile windshield system in from a perspective and front view respectively.
    The windshield (35) is located between two lateral guides (36) positioned vertically and a support with horizontal opening (37) located at the top of the lateral guides. In addition, the lower part of the windshield is integral to a fastener (38) that moves through a structure (39) with guides (40), which is in turn attached to the joints of the steering columns. The clamp (38) is connected to two traction cables, one at the top (41) and one at the bottom (42). These tensile cables are fixed to the ends of the structure (39) and in turn connected to an electric motor (43) and protected by two rubber covers (44).
    Depending on the direction of rotation of the electrical system, the upper cable is pulled and the windshield rises or the lower cable is pulled and the windshield descends. The windshield is held by the vertical guides and the support with horizontal opening, with a part of the windshield always resting on the horizontal support (even in its highest position) so that the windshield does not move due to the action of the aerodynamic force. In addition, the mechanism has a self-locking system by which it only moves by the action of the engine and not by that of external forces.
    There are two limit switches (45) located on the lower and upper stop which are responsible for stopping the movement of the motor when it reaches the extreme positions. The motor movement is activated from the control panel and depending on the time it is pressed, the windshield can be raised or lowered more or less and can also be in intermediate positions.
    As already mentioned, due to the aerodynamic force when the system is activated, that is, when the windshield is elevated, a thrust force generated by the wind is produced on it, this thrust force must be supported by the windshield. and transmitted to the rest of the vehicle.
    The windshield is jointly attached to the fastener (38), but in addition the windshield is also supported by the upper horizontal support (37), allowing a better load distribution as can be seen in Figure 13.
    In Figure 14 you can see a plan view of the support with horizontal opening (the geometry varies depending on the vehicle model). An elastic element (46) is located in the opening of the upper support that allows the windshield to move without problem, and also brings the windshield in contact with the support allowing the transmission of cargo to the rest of the vehicle. 5
    One of the problems to avoid is that due to the force of the wind the windshield drops when it is not desired.
    Several solutions are possible for this, one of them is to block the mechanism that causes the windshield to move when it is not activated by the user in the control panel. For this, it is possible to use a self-locking system in the motor, that is, when electricity does not reach it, it is blocked causing it to not be moved by external forces. The locking can also be done by transmission using an endless screw wheel transmission, this mechanism is not reversible, that is, the screw can move the wheel but the wheel cannot move the screw because it is locked. They can also be used for a transmission of 15 non-reversible helical gears, which due to the contact angle between the teeth only one of the gears can move to the other.
    Another way is to use a fastener that prevents unwanted windshield displacement. To this end, mobile fasteners can be placed which, when the windshield is moved due to the effect of the motor, are deactivated, and when it stops moving, they are actuated by setting the windshield position.
