These elements are constitutive of a vehicle driving upright, the scapular axis of the driver being substantially parallel to that of the movement of the vehicle.

Description

The present invention relates to a pendulum steering system of a vehicle, and a land vehicle with electric propulsion engine equipped with such a system. However, it will be appreciated from reading the description below that the systems, methods, devices and equipment which characterize the invention can be used by other types of vehicles.

The skateboards, or skateboards, and their multiple variations, do not offer the possibility of maintaining the driver on the vehicle deck in case of a sudden stop of said vehicle. In this type of situation, the pilot is almost always landed. In the case where the feet of the driver are maintained on the board by links or bindings: these links or bindings do not prevent the fall of the driver during a sudden stop, but most often cause the vehicle in this fall. This safety problem is all the more acute as the vehicle is motorized, so fast.

The present invention is intended to provide solutions to this safety problem, while providing the driver with driving sensations close to those felt when driving a longboard or a windsurf board.

Indeed, the vehicle described in this document behaves upright, the axis of the driver's shoulders being substantially parallel to that of the movement of the vehicle.

In addition, the steering control system of this vehicle comprises a pendular pod on the platform of which the pilot is standing. This nacelle, suspended above the ground, and whose oscillation is generated by the displacement of the weight of the pilot, acts on the steering members of the vehicle through transmission and movement transformation means. Using this control system, the pilot turns the vehicle leaning forward or backward.

The appended figures represent an embodiment of the invention. The appended figures show the invention realized in a configuration where the pilot drives with the right foot back.

According to one characteristic of the invention, the vehicle has a structure comprising a plurality of tubes which, after junctions, form a tube in one piece. This tubular structure is made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of said vehicle.

According to one embodiment:

Cables for providing controls necessary for driving the vehicle are located inside the tubular structure.

The vehicle is equipped with a motor-wheel (101), which ensures the motor and the direction of the vehicle.

This motor-wheel is held by a fork (102). This fork is secured to the tubular structure by means of a device allowing its rotation independently of said structure.

This structure can be considered as a succession of seven elements, besides the fork: - A stem (103) which extends the fork. - An elbow (104) (Fig. 3), which extends the stem. - A ramp (105) that extends the elbow. - An arm (106) which extends the ramp. - A part of the vehicle situated at the front of the vehicle, and called "axle" (Fig. 4) in the remainder of this document. A wheel A (107) (406). A wheel B (108) (407).

The stem (103), which may be rectilinear, rises above the ground at a variable height according to the embodiment. Advantageously, the end of the bracket located opposite the fork is curved towards the front of the vehicle. The dimensions of the stem are variable according to the embodiment.

Advantageously, the first portion (301) of the elbow extends the stem, particularly in a plane parallel to the ground and in the median longitudinal axis of the vehicle. Advantageously, the end (302) of this first part of the elbow has a clogged section of a part made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of the vehicle. Advantageously, in the center of this piece is made an orifice (303) for receiving a rod (501) attached to the balance (204) (503) of the nacelle (109) pendular. Advantageously, near the orifice (303) is formed a hole (304) intended in particular for the installation of cables. According to the embodiment, it is necessary to provide the tube constituting the elbow diameter sufficient for said cables do not interfere with the installation and movement of the rod (501). The dimensions of this first part of the elbow are variable according to the embodiment.

Advantageously, the second portion (305) of the elbow extends the first forming, at the section (302), a curve, in particular in a plane parallel to the ground. This second part of the elbow may be oriented on one side or the other of the median longitudinal axis of the vehicle, depending on whether said vehicle is designed to be driven with the right foot backwards, or to be driven with the left foot. backward. Advantageously, the end (306) of this second part of the elbow located opposite the first, is curved towards the front of the vehicle, in particular in a plane parallel to the ground. This second part of the elbow is of variable dimensions according to the embodiment.

The ramp (105), which can be rectilinear, extends the end of the second part of the elbow. Advantageously, the axis of the ramp is parallel to the longitudinal axis of the vehicle. Advantageously, the end of the ramp located opposite the elbow is curved towards the ground. The dimensions of the ramp are variable according to the embodiment.

The arm (106), which may be straight, extends the ramp to the ground to a variable ground distance according to the embodiment. Advantageously, the end of the arm located opposite the ramp is curved towards the front of the vehicle. The dimensions of the arm are variable according to the embodiment.

The junction of the arm and the first part of the axle, is called "cross" (201) (401) in the remainder of this document. This cross may be curved towards one or the other side of the median longitudinal axis of the vehicle, depending on whether the elements that it extends are made for driving "right foot back", or for driving "left foot backward ".

Advantageously, the first portion (402) of the axle extends the crossing in an axis parallel to the transverse axis of the vehicle. The dimensions of this first part are variable according to the embodiment.

Advantageously, the second portion (403) of the axle is curved towards the front of the vehicle, then has a second curve oriented towards the median longitudinal axis of the vehicle. The dimensions of this second part of the axle are variable according to the embodiment.

The third portion (404) of the axle, which can be rectilinear, extends the second portion along an axis advantageously parallel to the transverse axis of the vehicle. The dimensions of this third part of the axle are variable according to the embodiment.

Advantageously, an orifice (405) is formed in the second part of the axle, at the point of projection of the central longitudinal axis of the third part of the axle, in one embodiment where said third part is rectilinear and parallel to the transverse axis of the vehicle. This orifice is intended to receive an axle stub axle passing through the hub of wheel A (107) (406). Advantageously, one or more guides and a fastening system are installed inside the axle to guarantee the integrity and fixing of said rocket. Advantageously, near the orifice (405) is made a hole, in particular to allow the installation of cables.

Advantageously, the end of the third portion (404) of the axle located opposite the second (403) is plugged with a piece made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of the vehicle. Advantageously, in the center of said part is made an orifice for receiving an axle stub axle passing through the hub of wheel B (108) (407). Advantageously, one or more guides and a fastening system are installed inside the axle to guarantee the integrity and fixing of said rocket. Near the orifice for receiving the rocket is a hole allowing in particular the installation of cables. The dimensions of the third part of the axle are variable according to the embodiment, but such that the wheels A and B may be equidistant from the median longitudinal axis of the vehicle. Cables which can be installed inside the axle, it is necessary to provide the tube which constitutes the axle a sufficient diameter so that said cables do not interfere with the installation of the axle stub axles passing through the hubs of the wheels A and B.

For models made for a "right foot back", the distance separating the cross of the wheel A is shorter than that separating the cross of the wheel B. Conversely for models made for driving "left foot back" .

In a particular embodiment, the arm can be curved towards the median longitudinal axis of the vehicle, in addition to its curvature towards the ground. In this embodiment, according to the angles of the curves of the arm, the crossing may be equidistant from the wheels A and B.

In another particular embodiment, the arm may form, in addition to its curvature towards the ground, a curvature bringing its opposite end to the ramp beyond the median longitudinal axis of the vehicle. In this embodiment, the distance separating the cross of the wheel A is, for the models "rear right foot", longer than that separating the cross wheel B, and vice versa for the models "left foot drive in back ". The hunting angle of the fork (102) causes a lateral inclination of the stem during the rotation of the fork, which gives heeling to the vehicle in turns. To prevent this inclination of the stem from causing torsion of the tubular structure, the axle has joints (202) (408) allowing a coherent inclination of said structure in the turns, while allowing the inner front wheel to turn to remain substantially perpendicular to the ground. Advantageously, one of these joints is located on the first part of the axle, at a variable distance from the wheel A, according to the embodiment. Advantageously, another of these joints is located on the third part of the axle, at a variable distance from the wheel B, according to the embodiment. These joints are equipped with damping devices and stops to limit the opening of these joints to a variable angle according to the embodiment, to avoid the overturning of the vehicle in turns.

The tubular structure vehicle described above is adapted to the swing platform described below. However, upon reading the above description, it is apparent that said vehicle may be equipped with other types of steering controls. It will be noted that this vehicle is characterized in that its tubular structure is made in one piece, regardless of its steering system, or its number of wheels, or its number of steering wheels and their locations on said structure, or its number of floats, or skis, or skates, or caterpillars; or its engine, or its mode of propulsion or the surface on which a vehicle equipped with such a structure is caused to move.

According to another characteristic of the invention, the steering control of the vehicle is a pendular nacelle (109) advantageously comprising a platform (203) on which the pilot stands, and a rocker (204) (503) secured to said platform.

It should be noted that this pendular platform is not supported by one or more parts placed under its platform, but suspended above the ground by means of the pendulum.

The platform of the swing platform is made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of the vehicle. This platform is of variable size and shape according to the embodiment.

The properties of the balance, particularly as regards its robustness, may be equivalent to those of the tubular structure. This pendulum, which can be straight, is attached to the platform and rises above the upper face of the platform. This balance is of variable size and shape according to the embodiment.

Advantageously, the rocker is secured to the platform by means of a device for adjusting the position height of the platform. This device therefore allows, depending on the size of the pilot, to adjust the distance between the platform and the ramp (105) so that the shoulders of the pilot are at the height of the ramp. Thus, the pilot can easily cling to the ramp to maneuver the pendular pod. The properties of said device, particularly as regards its robustness, are sufficient to meet the constraints imposed by the construction and driving of the vehicle.

Advantageously, the pendulum transmits the movement of the pendular nacelle, caused by the displacement of the weight of the driver, to the steering members of the vehicle, by means of transmission and movement transformation.

Advantageously, at the end of the beam located opposite the platform is fixed a rod (501) (601) made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of the vehicle. Advantageously, this rod is oriented towards the rear of the platform (the rear of the platform being its limit located towards the rear of the vehicle). Advantageously, the end of this rod located opposite to that fixed to the balance, forms a conical toothed wheel of variable dimensions according to the embodiment. This rod is intended to be housed in the orifice (303). The dimensions and the shape of this rod are variable according to the embodiment.

Advantageously, in a portion of the beam, near the fixing of the rod (501) is formed a hole (502) including the installation of cables for insertion into the hole (304).

Advantageously, inside the bracket (103) (602) is installed a steering shaft (603) made of one or more materials with sufficient properties to meet the constraints imposed by the construction and driving of the vehicle. One end of this steering axis is attached to the fork head. The other end of this steering axis forms a conical toothed wheel of variable dimensions according to the embodiment. This gear is intended to form, within the tube forming the elbow-helix element (FIG 6), a gear with the gear wheel located at the end of the rod (601). The dimensions and shape of the steering axis are variable according to the embodiment.

Advantageously, one or more guides are installed inside the stem and inside the elbow, to ensure the integrity of the rod (501) (601) and the axis (603) direction. Advantageously, a holding device is installed inside the elbow, in order to avoid disengagement of the rod (601) from the orifice (303) while driving the vehicle.

In addition, cables that can be installed inside the stem and the elbow should be provided to the tube which constitutes the stem and the elbow, a sufficient diameter so that the cables do not hinder the movement of the rod (501 ) and the steering axis (603). The gear formed by the gear wheels mentioned above, allows the pendular pod to cause rotation of the fork. The pendulum platform allows a steering of the vehicle by moving the weight of the driver: hooked to the ramp, a driver driving with the right foot back rotates the vehicle on the right by leaning its bust forward and projecting the platform pendulum behind he with his feet, he turns the vehicle on the left by leaning his bust back and projecting the platform pendulum in front of him with his feet. For a pilot driving with the left foot backwards, it is the opposite. This gear system, allowing the transmission and transformation of the movement of the nacelle to control the steering of a vehicle, is cited herein by way of example. It can be replaced by any other relevant means, according to the embodiment, for transmitting and transforming a motion.

Furthermore, the pendular nacelle and the transmission and movement transformation means that it uses, can be made to obtain a reverse direction control to that described above. In which case: hanging on the ramp, a pilot driving with the right foot in bitter rotates the vehicle on the right by leaning his bust back and throwing the basket in front of him with his feet, he turns the vehicle left leaning his bust forward and throwing the basket behind him with his feet. For a pilot driving with the left foot backwards, it is the opposite.

It will therefore be noted that the invention is not limited to the embodiment described.

The pendular pod described herein is adapted to the tubular structure vehicle described herein. However, on reading the above description, it is obvious that said nacelle can be adapted to other types of vehicle. It will therefore be noted that this pendular nacelle is characterized by the steering control system that it constitutes and the types of control that such a system induces, regardless of the vehicle to which said system is intended or the nature of the transmission and control means. motion transformation used to correlate the movements of the nacelle to those of the steering bodies of a vehicle.

According to a general characteristic of the invention, the tubular structure - pendular pod assembly, constitutes a vehicle that drives upright, the axis of the driver's shoulders being substantially parallel to that of the vehicle movement.

According to another characteristic of the invention, a safety device comprising a furling link (205) (504) is attached to the balance (204) (503). Advantageously, the properties of this link, particularly in terms of robustness, are equivalent to those of an automobile safety belt. Advantageously, the properties of said retractor are equivalent to those of an automobile seat belt retractor. Advantageously, this retractor is attached to the balance by a height adjustable fastener. The mobile end of said link is intended to hang on a safety equipment worn by the pilot, for example a climbing harness. This safety device prevents the driver from being unloaded from the vehicle in the event of a sudden stop.

According to another characteristic of the invention, a control module (209) for reversing the polarity of the electric current makes it possible, in addition to driving the vehicle in reverse, to envisage the vehicle either in a "right foot back" configuration. "- propulsion /" left foot back "-traction; in a "left foot back" configuration - propulsion / "right foot back" - traction.

In addition: - The vehicle is equipped with a battery (206) of electric accumulators placed under the platform of the pendular platform. This battery is intended in particular to power the engine and the onboard equipment of the vehicle. - In addition to the battery, an onboard computer is fixed under the platform of the nacelle. This calculator communicates, in a wired or other manner, piloting indications, either to a terminal attached to the tubular structure, or to the pilot's smartphone, or to the connected glasses of the pilot. - The vehicle is equipped with a motor power supply control. This control can be a trigger (207) of accelerator actuated with the thumb, such as that of an electric quad, or any other device for managing the power supply of the engine, relevant according to the embodiment. - A handle (208) brake circuit complete the controls of the vehicle.

This vehicle is intended for sports, recreational and current travel.
