Motorized skateboard and engine control assembly

The constant effort to improve the quality of the urban environment, and in particular to reduce air pollution linked to road traffic, has enabled the development of new technologies in the field of transport. The improvement in the capacity of the batteries has notably enabled the arrival on the market of partially electric cars, called hybrid, then fully electric.

Biking is also experiencing renewed interest. It is in particular possible, thanks to the assistance of batteries integrated into the bicycle, to travel longer distances with reduced effort. These bikes are sometimes foldable, they can be easily taken on public transport, the user thus combines two complementary modes of transport, which allows him to save time in his travels, in particular between his home and his workplace. . Even a portable bicycle remains heavy, and the consecutive folding / unfolding cycles cause it to wear out prematurely.

Other devices have also appeared on the sidewalks. Electric scooters with controls integrated into the steering wheel are commonly used by adults.

Segways have also been developed, that is to say vehicles comprising one or two wheels aligned on the same axis of rotation and a platform, on which an individual can stand, possibly split into two positioned parts on each side of the wheel when the vehicle has only one wheel, with or without handlebars. A Segway moves thanks to a gyroscopic stabilization system in which the rotation of the wheels is activated in response to a loss of horizontality of the platform on which the user is standing. The user thus controls the movement of the Segway by a displacement of its center of inertia which induces a loss of horizontality of the platform. This gyroscopic stabilization is only compatible with systems with a single axis of rotation, that is to say one wheel or two wheels axially.

BE2017 / 5062 aligned, a higher number of axes does not allow to vary the horizontality of the platform. The circulation of Segways is, in many places, regulated like the circulation of bicycles, and must be done on the road, which can be dangerous in heavy traffic, the user being poorly protected in the event of collision with another vehicle.

The use of a skateboard, commonly known as a skateboard, is safer in this regard, its use being authorized on sidewalks. The skateboard can be easily transported by public transport, without having to be folded, it is increasingly used in town to reduce travel times, for example between home and a train station or a metro station.

Electric versions of skateboards are available on the market. They work with remote controls with buttons or levers to operate with the fingers and to be held in the hand of their user. However, the use of a remote control to control a skateboard on which one is standing is unnatural and has a number of drawbacks. In particular, the arms used to balance and move the body used to manage the direction, it is uncomfortable not to have your hands free, or to have to coordinate an arm movement with a finger action on the remote control. The remote control may suffer from adverse weather conditions, or be difficult to use with gloves.

These drawbacks are not limited to electric skateboards. They are found on any remote-controlled device by means of a remote control with buttons or levers, such as drones, or reduced models.

The applicant therefore deemed it necessary to address this problem and to propose a more ergonomic guidance system, not cluttering the hands.

BE2017 / 5062

Solution of the invention

To this end, the invention provides a set, on the one hand, of a skateboard, for a skateboarder, comprising at least one motor for controlling the progress of the board and, on the other hand, a device motor control comprising a gyroscope and arranged to be subjected to bodily movements of the rider.

For clarity, the function of the elements is the control of the running of the board, that is to say its movement, by actuation of the wheels, rolling, in one of its two longitudinal directions. These two directions are forward and reverse. The result is ergonomic guidance, leaving the boarder free.

An angular displacement measured by the gyroscope causes a predetermined action of the engine for controlling the running of the board.

This displacement is measured relative to a reference position, and can be zero, positive or negative and in any direction. The predetermined action of the walking control motor can for example be acceleration in forward or reverse, maintaining speed or slowing down.

In a preferred embodiment of the invention, the control device comprises a scheduling microprocessor connected to the gyroscope and wirelessly connected to a processing microprocessor included in an electronic engine control module mounted on the board.

The scheduling microprocessor and the processing microprocessor are arranged to cooperate with each other.

The engine control device may be included in a box arranged to be associated with a body member of the snowboarder.

Advantageously, this box is arranged to be placed on a hand, a wrist or an arm of the snowboarder. Other physical locations are also possible; it is however

BE2017 / 5062 necessary that they allow a sufficient range of movement for the proper functioning of the assembly. The case may be associated with a bracelet, a glove or any other device that can be adjusted to the body member or to a garment covering this body member.

Advantageously, the skateboard includes a detector of the presence of the skateboarder on the board arranged to cooperate with the gyroscope for controlling the engine.

The invention will be better understood help of the description next of several forms of production of The invention, in reference to drawing in annex on which : figure 1 represented a view schematic of All of the invention; figure 2 represented a view schematic of device of

engine control of the invention;

FIG. 3 is a functional diagram of the skateboard of the invention and FIG. 4 illustrates the movements of the arm of a snowboarder for the use of the assembly of the invention.

Referring to Figure 1, the assembly of the invention comprises, on the one hand, a skateboard 1 and on the other hand a control device 7. The skateboard comprises a platform (board) 3 mounted on casters 2. An electronic module 4 is placed under the board 3 and in radio link with the device 7 by a receiving antenna 5.

With reference to FIG. 3, the electronic module 4 of the board comprises a microprocessor 13 for processing and analysis connected to the receiving antenna 5, to a presence sensor 14, to a motor 6 here split into two motors 6a, 6b, with two electronic speed controllers (ESC) 15a and 15b, connected respectively to the two motors 6a and 6b respectively controlling the two driving wheels 2a and 2b. A battery 16 supplies the ESCs 15a and 15b with energy. The microprocessor 13 is also connected to a lighting module 17.

BE2017 / 5062

Here, two wheels 2a and 2b, arranged on the two lateral sides of the board respectively, are controlled separately by the two motors 6a, 6b. A skateboard generally comprising four wheels, it is possible to control the four wheels or only the front wheels or the rear wheels. It is also possible to order several wheels with a single motor.

The motors 6a and 6b are here brushless electric motors which can, on control of the microprocessor 13, actuate the wheels in both directions of rotation and can also prevent or limit this rotation, thus also acting as brakes.

The motors are supplied via the ESCs 15a, 15b here by a rechargeable battery 16. Other types of motors, electronically controllable, are nevertheless also possible. The battery 16 may be removable.

The device 7 for controlling the motors 6a, 6b is connected to a transmitting antenna 8 to cooperate with the receiving antenna 5 and the control device 7 is placed in a case 17 mounted on a bracelet 9.

With reference to FIGS. 1 and 2, the control device 7 comprises a gyroscope 10, an accelerometer module 18 and a scheduling microprocessor 11 connected to the gyroscope 10 and to the accelerometers 18, as well as to a battery 12 and to the transmitting antenna 8.

The whole of the invention having been described, its use will now be able to be addressed.

The gyroscope 10 of the control device 7 is arranged to control the motors 6a and 6b for controlling the running of the board.

In practice, a snowboarder has the wrist bracelet and stands on the board around his

3. He may have previously switched on the control device 7 of the bracelet 9 and / or the electronic module 4 of the board using an ignition button or any other type of actuator. It is possible to plan to enter a code

BE2017 / 5062 security or having to insert a key or equip the whole with an anti-theft system.

In the initial position or reference position, the snowboarder has his arm alongside his body. To trigger a particular action of the motors 6a and 6b, the snowboarder performs a particular movement of the arm, and therefore of the wrist on which the bracelet 9 comprising the control device 7 is placed.

The deviation of the wrist from its reference position is measured by the gyroscope 10 of the control device 7.

Referring to Figure 4, showing the arm of a snowboarder on which is placed a bracelet 9 with its control device 7, the angular deviation θ of the wrist can be broken down into several axes of rotation x, y and z. The x axis here is the axis perpendicular to the plane of the body of an individual in a standing position, the y axis is the axis connecting his shoulders (substantially horizontal) and the z axis is the axis (substantially vertical) of the arm of this individual placed along the body. The angular components of rotation around these axes are θχί, θγί and θζί respectively. At the reference position, these components are ΘχΟ, θγΟ and θζθ and their value is zero. Depending on the direction of rotation, the angles have a positive or negative value.

For example, for a case 9 placed on the right wrist of an individual, and relative to the reference position:

- 0xi> 0 when the wrist rotates away from the body to the right in the plane of the body;

- 0yi> 0 when the wrist rotates away from the body forwards; and

- 0zi> 0 when the wrist pivots to the right, clockwise, around the axis of the arm.

The angular values measured by the gyroscope 10 are communicated to the scheduling microprocessor 11 which structures them, or orders them, in order to communicate them, in a precise format, to the processing microprocessor 13 of the board by means of a communication. wireless between the two antennas, in fact connected, one to a transmitter connected to the scheduling microprocessor 11 and, the other, to a receiver

BE2017 / 5062 connected to the processing and analysis microprocessor 13. Communication between the antennas 8 and 5 can also be done by bluetooth, or any other wireless communication technology.

Modern electronic technologies have allowed the miniaturization of gyroscopes or the development of equivalent devices. The notion of gyroscope is therefore to be understood here in the broad sense. The gyroscope 10 can, depending on the nature of the electronic component, communicate to the scheduling microprocessor 11 angular values, displacement values along each axis, or other values representative of the spatial positioning of the device from which the microprocessor 11 can reconstitute angular displacement values.

The processing microprocessor 13 is arranged to analyze and compare the angular displacement values θχί, Oyi and θζί received with ranges of values from an instruction table which have been previously informed therein to determine the action to be commanded from the motors. This instruction table establishes correspondences between angular displacements θχί, θγί and θζί, or ranges of angular displacement, which can be measured by the control device 7 and actions to be controlled by the motors 6a and 6b. The instruction corresponding to the combination of measured angular values is then communicated to the electronic speed controllers 15a and 15b which then trigger an action of the motors 6a and 6b which control the wheels 2a and 2b. These instructions can be, for example, accelerate in reverse, slow down, maintain constant speed or accelerate in reverse.

The accelerometer module 18, connected to the scheduling microprocessor 11, here comprises three accelerometers. These make it possible to measure the accelerations Ax, Ay and Az of the movements of the wrist on which the device 7 is placed, along the three axes x, y and z respectively. These acceleration values are transmitted, via the scheduling microprocessor 11, to the microprocessor 13 of the board in the same way as the values

BE2017 / 5062 angular. These values can also be analyzed and compared with the values of an instruction table previously filled in to order actions for the motors 6a and 6b. The same instruction table can also combine the angular values and the acceleration values.

The instructions can be varied and relate, in addition to the engine, to actions of other components of the skateboard 1, such as for example the lighting of headlights 17, or the activation of the remote control or the adjustment of the maximum speed. .

An example of an instruction table to which the processing microprocessor 13 compares the angular values and measured accelerations is given below.

θχϊ 0yi 0zi Ax Ay Az Accelerate 30 ° <θχί <90 O -9O ° <0yi <9O ° Slow down 9O ° <0yi <195 ° Brake - 90 ° <θχί <- 30 ° -9O ° <0yi <9O ° Maintain speed -30 ° <θχί <30 ° -9O ° <0yi <9O ° Control at distance: moving forward 9O ° <0yi <195 ° 0 ° <θζί <180 ° Control at distance: back off 9O ° <0yi <195 ° -180 ° <0zi <0 ° Activate the control at distance 9O ° <0yi <195 ° > + lg Deactivate the control at distance 9O ° <0yi <195 ° <-lg Light up the fog lights 9O ° <0yi <195 ° > + lg

BE2017 / 5062

Switch off the fog lights 90 ° <0yi <195 <-lg Limit the speed at 10 km / h 9O ° <0yi <195 ° > + lg Limit the speed at 25 km / h 90 ° <0yi <195 <-lg

According to this table of instructions, when the snowboarder, who wears the control device 7 on his wrist, separates his arm from his body between 30 ° and 90 ° to the right while keeping his arm more or less in the plane of his body , board 1 will accelerate. To brake, the snowboarder must keep his arm more or less in the plane of his body and move his arm to the left between -30 ° and -90 °.

A certain number of commands relate to a remote control of the board. In this case, according to the instruction table, the snowboarder must bend his arm so that the device “turns over” so that the rotation around the y axis is in an angular range between 90 ° and 195 ° . The acceleration of this movement will activate or deactivate the remote control, depending on the direction of movement. After activation of the remote control, a rotation of the wrist around the axis z of the arm, according to the direction of rotation, induces a movement of the board 1 forwards or backwards.

This feature can be useful for storing board 1 for example, or removing it from its garage location.

The lighting of the headlights can also be controlled in a similar way. A total of six parameters can be combined here to control various elements of the board, the range of possibilities is obviously much wider than the simple functionalities described here. Other accessories can be integrated into the board 1. Although here, as regards the running of the board, only the front and rear steps are controlled by the control device 7, it is also

BE2017 / 5062 conceivable to provide directional controls allowing board 1 to turn left or turn right.

It is obvious that these instruction values are described by way of example and that any other programming is possible. Other accessories can also be installed on the board 1 and controlled by movements of the control device 7. The instruction table can be entered during the manufacture of the assembly. It can also be envisaged that the processing microprocessor is connectable to a computer system and that the instruction table can be personalized by the snowboarder via an appropriate interface. For example, an application can allow the snowboarder to inform if he is

right or left handed and sure what member is placed the device of command, which can to have an influence on The beaches of angular displacement at match to actions at order to motors. The presence sensor 14 can , for example, being a sensor of pressure placed on the board at the level or the snowboarder must

place a foot. When the boarder places his feet on the board, the sensor 14 communicates to the processing microprocessor 13 the presence of the boarder on the board 3. This information can be combined with other information processed by the microprocessor 13. For example, certain commands may not be effective only if the rider is present on the board, or vice versa. Other presence sensor systems are also possible.
