    Propulsion system for snowboards with retractable motorized caterpillar wheels and remote control. System that incorporates a mechanism of electric propulsion to a snowboard, controlled remotely and wireless by the user and that is screwed to the table in the holes of the fixings for the boots. The invention is based on a system of two motorized and retractable caterpillar wheels, one for each side of the board.

The change of position is done manually and a set of bars with springs guarantees that the wheels are in an equilibrium position in both states. The caterpillar wheels ensure a good grip on snowy surfaces. (Machine-translation by Google Translate, not legally binding)

    DESCRIPTION

    Propulsion system for snowboards using retractable motorized track wheels and remote control
     5
    SECTOR OF THE TECHNIQUE

    All kinds of snowboards for adults with standardized fixing holes.
     10
    BACKGROUND OF THE INVENTION

    Existing precedents related to the propulsion of snowboards are quite scarce. Those patents that present some similarity to the invention presented here are summarized below. fifteen

    In patent ES 2120856, dated May 17, 1995, a sliding board with motor and track or tilting band is described, for use in snowy or similar terrain. This invention consists of a ski board that incorporates a motor and a ground force transmission system in its lower part, by means of a track or an endless band. This system can be decoupled to avoid contact with snow.

    In US Patent 5662186, dated September 2, 1997, a modified snowboard is described to be able to couple a propulsion system. It consists of a 25 board with the slightly inclined rear part (6 °), where the motor and the drive system are incorporated.

    In the patent ES 2393199, of November 21, 2005, a personal vehicle with longitudinal axle chassis with platform for the user is described. It consists of two 30 track units (front and rear), one of which, at a minimum, is motorized.
    The function of these devices is very similar to what is stated here, but the basic difference lies in the fact that it is a set that includes table and propeller system, while the invention set forth in this document 35 consists of a independent propeller designed to be incorporated into any board
    of snowboard marketed.

    The following patents correspond to accessories to propel the snowboard, that is, they can be coupled and decoupled from said object.
     5
    In US 6193003, of February 27, 2001, a propulsion device designed for use by skiers, snowboarders and the like is described. It consists of a device that drives the user through contact with the ground, and joins the skier through a rigid bar that is fixed to it thanks to the use of a belt. When the propeller is not used, it can be transformed into a backpack 10 for easy transport.

    In US 6698540, of March 2, 2004, a propulsion apparatus for platforms such as a snowboard is described. It consists of a drive system that joins the rear part of the sliding object and allows its rotation 15 with respect to it.

    In US Patent 2004/0154849, of August 12, 2004, a snowboard propulsion apparatus is described. It consists of a system with engine and track wheels that are mounted on the bottom of the back of the board, so that it is slightly tilted forward. If it is disassembled it can also be carried as a backpack.

    EXPLANATION OF THE INVENTION

    The invention is constituted by various systems. The most important is the motor system 25 composed of two track wheels like those of Figure 4, located on both sides of the snowboard (27), and formed by: the track belt (15), the motorized cogwheel (14) that transmits the movement to the track belt and two smooth rollers (16, 16 ') that tension the belt and guarantee the contact of the belt with the ground. The whole assembly is connected to each side by a T-shaped bar (17), which is articulated in the axes (18, 19, 20). Each track wheel is connected to the state change system of said wheel thanks to a U-shaped tooling (21), one for each wheel. The tooling is articulated to the wheel through the pin holes (20 ', 20' ') and to the state change system in the pin hole (9'). The projection containing the hole (9 ') is welded to the U-shaped bar (21). 35

    The user manually activates the system that changes the state of the wheels (see Figure 3) and, through the remote control system (see Figure 5), issues orders to make changes on the state of the propeller, which can only be activated when the two track wheels are in contact with the ground. The sensors (33, 33 ') are responsible for controlling the position of the wheels. The power supply system contained in the housing (13) feeds the motor system. The latter transforms electrical energy into mechanical energy in the form of rotation of the sprocket axle. The ground contact system takes advantage of the rotation of the motor shaft to move the device thanks to the gear between the gearwheel (14) and the track belt (15). The forward speed is regulated with a regulator system based on a potentiometer connected to the motor and governed by the orders issued by the user. Said speed and other data of interest are shown to the user by means of the display system present on the remote control. Finally, the protection system is responsible for protecting the invention and the fastening system (see Figure 7) the anchor to the snowboard. fifteen

    a) Motor system
    Two electric motors are responsible for transforming electrical energy into mechanics. Each electric motor is contained within a cogwheel (14) that transmits the movement to the track belt. The cogwheel itself is part of the trackwheel assembly (see Figure 4). The operation of the invention consists in:

    1) Receiving current from the batteries contained in the housing (13), of magnitude regulated by the control unit. 25

    2) Transformation of electrical energy into mechanical rotation energy.

    3) Transmission of the rotation to the track belt using the teeth of the motorized wheel (14). 30

    The motors can only be started at the user's request with the remote control shown in Figure 5, as long as the track belts (15, 15 ') are in contact with the ground. They turn on and off simultaneously and transmit the same torque to the shaft. 35

    b) Direct contact system with the ground.
    The two track wheels are responsible for advancing the snowboard on a snow surface thanks to the mechanical energy obtained from the electric motor located inside the cogwheel (14). In direct contact against the snow is the track belt (15) that moves thanks to the rotation of the motorized sprocket 5 (14) (see Figure 4) and is responsible for giving linear speed to the board thanks to friction with the ground .

    The reason that the invention consists of two wheels that are deployed symmetrically with respect to the longitudinal axis of the table (see Figure 2) is because the sum of momentum with respect to said axis must be equal to zero so that the wheels move linearly the snowboard. In the event that the sum of moments in the longitudinal axis is different from zero, that is, that the wheels are at different distances from said axis, the table would rotate on itself.
    The track wheels are connected to the state change system by means of tooling 15 (21) (see Figure 6). The tool joints with the bar (3) and the gearwheel shaft (14) are articulated. The position and speed of rotation of the trackwheels are detected by the sensors found in said wheels:

    1) The position sensors are responsible for controlling the position of the wheels and 20 informing the control unit contained in the housing (13) to prevent the sprockets (14) from being put into operation without the track wheels being ground contact. These are sensors located on the structure of said wheels that control the ground clearance at all times. 25

    2) The speed sensors determine the speed at which the sprocket motors are rotating (14) and inform the control unit contained in the housing (13) to release the motor shaft in case the speed is excessive. c) Wheel status change system 30

    It is necessary to be able to lift the wheels to avoid being in contact with the ground when a descent is being made along the ski slopes. In addition, to prevent the incorporation of the system from influencing the normal development of the activity, when the wheels are folded they should not protrude from the width of the snowboard. The invention is responsible for allowing the permutation of the position of the wheels of a
    working state in contact with the ground to a resting state without contact with the ground and vice versa and guarantees balance in both positions. The change of state of the wheels must be done manually by the user. The operation of the invention consists in:
     5
    1) When the operation of the propeller system is not required, the elevated position of the wheels is maintained.

    2) When it is necessary to propel the snowboard because the slope of the ski slope is insufficient, the user can deploy the wheels 10 until they reach the ground contact.

    As can be seen in Figure 3, the system contains springs (1, 1 ’) that are responsible for guaranteeing the two balance positions of the wheels. The change of state is produced by the user with the rotation of the bar (3) with respect to the pin (8) 15 with a force that overcomes that exerted by the springs (1, 1 '). These springs also perform the function of cushioning the caterpillar belt wheels (15, 15 ').
    There are two caterpillar wheel status switches and each one deploys a wheel to the side of the snowboard. With the wheels deployed in contact with the ground, the propulsion system does protrude from the board, but since the two wheels are deployed symmetrically with respect to the longitudinal axis of the board, the center of gravity of the assembly remains above of said axis (see Figure 2).

    d) Remote control system 25
    When the wheels are in contact with the ground, the speed of rotation of the track wheels can be controlled remotely by means of the command shown in Figure 5, which emits information wirelessly for the modification of the state of the engine of the propeller. If the wheels are not in contact with the ground, any action taken on the remote control will have no impact on the propulsion system. The operation of the invention consists in:

    1) Pressing the trigger (10) of the remote control of Figure 5 generates a signal proportional to the angle turned by it from its equilibrium position.
     35
    2) The signal is emitted to a receiver located in the control unit that
    It is contained in the housing (13), which performs the necessary actions on the gearwheel motor (14).

    The design that can be seen in Figure 5 is designed to take the control with the palm of the hand by the handle and control the trigger with the index finger. The 5 command is turned on and off by the button (11) and is powered by a battery located in (12).

    e) Power supply system
    The motor system is powered by electric batteries located inside the housing (13) that provide the necessary power to operate, that is, so that the necessary torque can be made to properly move the snowboard with the user over. The amount of power supplied is required by the user with the remote control through the trigger (10) (see Figure 5) and the unit responsible for regulating the output power of the batteries is the control unit. 15 In addition, the position sensors (33, 33 ') of the wheels need to be powered and the batteries themselves are responsible for doing so.

    f) Clamping system
    The invention is anchored to the snowboard by means of the perforated plate (22) 20 which is placed in contact with the upper surface of the board, being placed between the board and the ski boot fixings (see Figure 2). The holes of this plate are properly located so that the holes necessary to install the fixings of the boots match those used to fix the plate to the board, thus avoiding making new holes (see Figure 7). In this plate the two 25 state switching systems of the track wheels are screwed into the hole assemblies (25, 26), restricting any movement of said systems with respect to the snowboard. The housing (13) containing the electrical and electronic components of the propulsion system is also fixed on this plate.
     30
    g) Data display system
    To inform the user of the status of the invention, the light indications (29, 30, 31, 32) located on the remote control are used (see Figure 5). The operation consists of:
     35
    1) The indicator (29) comes on when the wheels are in the position of
    job. If this is turned off, the invention does not respond to user commands from the remote control.

    2) Indicator (30) reports the status of the engine. If it turns red it means that the engine is not working properly due to some technical problem and if 5 is green the engine is running.

    3) The row of lights (31) indicates the battery level being maximum when all are on and zero if they are all off.
     10
    4) The set of indicators (32) reports the rotation speed of the axis of the
    engine; when all the lights are on the speed is maximum and when they are off the engine does not exert torque on the shaft.

    The same battery located in (12) that powers the order issuing system is responsible for supplying power to the data display system.

    h) Speed regulator system
    In order to modify the speed of advance it is necessary to increase or reduce the input voltage of the motors according to the setpoints transmitted by the issuing system 20 of orders. The speed regulating system is composed of a potentiometer regulated by the control unit that acts according to the information received from the remote control through a wireless receiver. The operation consists of:
     25
    1) Depending on the trigger position (10) of the remote control, the control unit acts proportionally by changing the value of the variable resistance of the potentiometer. In this way, more or less voltage is transmitted to the electric motors.
     30
    2) Depending on the electrical voltage transmitted to the motor, the speed of rotation of the gearwheel (14) is modified.

    i) Protection system
    The housing (13) fixed to the clamping plate completely isolated from the outside covers and protects the control unit, the speed regulating system and the control system.
    power supply of possible blows during handling, transport or use of the snowboard.

    PREFERRED EMBODIMENT OF THE INVENTION

    Among the different ways of applying this invention, a possible configuration is set forth by way of example:

    a) Wheel state change system
    It consists of two springs (1, 1 ') attached to four projections (2, 2', 2 '', 2 '' ') that exert a certain force in both states of the track wheels to minimize the movement of the bar ( 3) with respect to the bar (4) and guarantee the equilibrium point in the two possible positions of said wheels. The bar (4) is integral with the support (5) that is fixed to the table thanks to the joints screwed in the holes (6). In the working state the angle formed by said bars is greater than 180 ° and in the rest state the angle is 30 °, the bar (3) being in contact with the stop (7) and the wheels between the legs of the user of the snowboard, not exceeding the width of the board. The union between the wheel and this system is done through the joint in the pin hole (9).

    b) Remote control system
    The device that can be seen in Figure 5 is a control integrated by about 35 components that detect the angle traveled by the trigger (10) and send the information
    through a wireless transmitter to the receiver that is in the control unit contained in the housing (13). The remote operates on batteries that are placed in (12).

    c) Motor system
    It is based on two internally motorized cogwheels (14), one on each track wheel 5. Each cogwheel includes inside an electric motor powered with a direct current of 1.1 kW, capable of transmitting torque to the axle of said wheels, achieving a maximum speed of 10 km / h. The nominal voltage of the motors is 93.6 V and weigh approximately 1 kg each. The teeth of the sprockets perfectly match the grooves of the track belt (15). 10

    d) Power supply system
    It consists of a set of lithium batteries of total voltage 96 V and capacity 2200 mAh, which can provide the power required to move the athlete-board set and have sufficient autonomy for a whole day of skiing. It has been calculated that the maximum power required by the motor system is 2 kW in case of going to the maximum speed. The batteries are contained in the protective housing (13) that is fixed in the clamping system, as seen in Figure 7.

    e) Direct contact system with the ground. twenty
    These are two track wheels, whose design can be seen in Figure 4, formed by: the track belt (15), the motorized cogwheel (14) that transmits the movement to the track belt and two smooth rollers ( 16, 16 ') that tension the belt and guarantee the contact of the tape with the ground. The whole assembly is connected to each side by means of the T-shaped bar (17), which is articulated in the axes (18, 19, 20). Each track wheel is connected to the state change system of said wheel thanks to two U-shaped tools, one for each wheel (see Figure 6). The tooling (21) is articulated to the wheel through the pin holes (20, 20 ’) and to the state change system in the pin hole (9). The projection containing the hole (9) is welded to the U-shaped bar (21). 30

    In order to know if the track wheels are in contact with the ground or not, ultrasonic position sensors (33, 33 ') are used that allow the effective detection of the position of said wheel by means of ultrasonic sound waves that send and receive. The ground reflects the sound waves and the distance is calculated by measuring the flight time. These sensors are located in the bar (17) of the wheels of
    caterpillar. To determine the speed of the motors, there is a turn counter sensor on each of the sprockets (14) of the two trackwheels that measures how many turns the motor shaft turns per time interval and communicates it to the control unit. All the information collected by the sensors is sent to the control unit.
     5
    f) Clamping system
    It consists of the plate (22) with two sets of pin holes, (23, 24), and two sets of incoming holes, (25, 26) (see Figure 7). The sets of pin holes (23, 24) allow the fastening of the fasteners to the table as in their usual use and are responsible for securing the plate to the table (27). The sets of 10 incoming holes (25, 26) allow the anchoring of the systems that switch the position of the track wheels to the plate. The latter are on each side of the housing (13) staggered to prevent the track wheels being in a position of no contact with the ground, that is, with the wheels folded, they do not touch each other (see Figure 1) . fifteen

    g) Data display system
    The light indications seen in Figure 5 are LEDs of different colors. The indicator (29) is a green LED. The indicator (30) is a bi-color, red and green LED. The rows of indicators (31, 32) consist of LEDs of the same color, row (31) red and row (32) green. All LEDs are powered by the battery located in (12).

    h) Speed regulator system
    The potentiometer used to modify the voltage that goes to the electric motors 25 is fixed on the base plate and contained in the housing (13), will provide a null voltage, if it is not being used, or between 12 V and 96 V, in operation, according to the speed required by the user.

    i) Protection system 30
    The housing (13) is screwed to the base plate so that its interior is completely isolated from the outside. A rubber gasket is placed between the base plate and the housing to prevent water from entering.
