Abstract

The invention is a pedal motor which multiplies a slow rotational movement from a low muscular effort made by an operator. It is composed of several members whose role is to transmit a slow rotational movement by multiplying it to drive a mechanical device or to equip and drive a light vehicle or to be embarked in an electric vehicle to occasionally charge its battery. The multiplication and transmission of the rotational movement are done by gear play or an interactive play of a main toothed attack wheel (1) driven by an eccentric pedal (2), a main energy transfer wheel (6) and a weighted tenfold wheel (7), by means of pulleys (3, 8 and 9) and transmission belts or chains (4 and 4').

Description

DESCRIPTION OF THE INVENTION

Pedal motor increases torque and speed with minimal muscle effort

The invention relates to a pedestrian or manual pedal motor, designed to produce a mechanical rotational movement from muscular force and increased n times such that n >10, through a reduction gear box with gears or non-interactive by belt or chain transmission in dry or wet dock. The transmission is moved by an eccentric pedal coupled to a stepped differential ratio allowing, with less muscular effort which is not taxing for the operator, to convert a slow rotational movement into a reduced and coupled speed.

The pedal motor according to the invention is intended to drive a mechanical device such as a dynamo for recharging an accumulator battery, a grinder, a threshing machine, a sheller, a crusher, a pump and any other related device or else to be embarked in an electric vehicle to recharge quickly in emergency and on an ad hoc basis, its battery in the event of energy distress in an area without charging terminals. All these options make the invention a rational and effective alternative to dependence on fossil fuels, the conventional electricity grid and charcoal.

A motor is by definition a device capable of transforming or converting energy into mechanical motion. The history of mechanics really begins with Galileo, but this science has its roots in much older knowledge, in particular with the reflections of Archimedes and Aristotle. Until the 19th century, the notion of mechanics encompassed both the scientific study of moving bodies and the theory of machines.

In the revolution of the times, thanks to the research of engineers and inventors, each in their respective specific fields have been designed different types of engines, namely, among others:

- the balance motor and return spring, invented by Abraham Louis Perrelet in watchmaking and who was also the inventor of the mechanical movement;

- heat engines: in this case, these are engines:

• steam, approached by many British engineers, including James Watt who invented a high-performance steam engine in 1769;

[2] • combustion, the fruit of 4 years of research by engineer Rudolf DIESEL, from 1893 to 1897. This engine subsequently underwent extensive development through different types of engines such as: the internal combustion engine (2 time and 4 times), the hydrogen engine, (not popularized), the electric motor and the magnetic motor, (not popularized).

- Other engines: we distinguish the particular engines and not yet popularized such as the nuclear engine, with hot fission (for the power stations and others), the nuclear engine with cold fission, the engines with reaction, stato-reaction, pulso-reaction and rocket engines.

All these motors have the sole function of moving or propelling a body. They have the advantage, thanks to research and technological advances, of being reliable, efficient and resistant, but all have the same disadvantages, that of being dependent on fossil fuels or the electricity grid. Their maintenance generates an almost permanent need to find expensive spare parts that are often unavailable and maintenance costs requiring skilled labor.

Since then, man has constantly expressed his need for independence from national electricity networks, the implementation of which is slow and costly and above all because of the numerous untimely cuts. The most commonly used alternative solutions are solar energy and generators. The installation of solar energy has a very high cost and occupies a lot of space. This energy is also intermittent, its performance varies with the weather, it depends on the climatology, which automatically eliminates the possibility of having recourse to it in regions where cloud cover is constant and/or the solar weather is shorter. In addition, the inclination of the sun relative to the surface varies on different days of the year and this has an influence on the performance of solar panels. In order to overcome these difficulties in terms of energy supply, many solutions are being considered.

The patent WO/2019/166402 filed on February 26, 2019 by "E2 Drives" and published on September 06, 2019, entitled "Powertrain for a pedal vehicle" presents a pedal vehicle powertrain which comprises a pedal spindle and a first output tray having a first axis of rotation. The first output tray is coupled with a transmission chain or belt so as to drive the rear wheel of the pedal vehicle. The coupling between the crank axle and the transmission chain or belt passes through

[3] a planetary gear rotating around a second axis of rotation. The bottom bracket axle is further coupled to the first output chainring by a first freewheel arranged to prevent the first output chainring from rotating slower than the bottom bracket axle when the bottom bracket axle rotates in the normal direction of pedaling . The object of the invention being to provide a powertrain capable of providing good performance whatever the operating conditions, even without electrical power supply and a powertrain whose transmission does not slip, in order to make driving more pleasant. However, this device has the disadvantage of not increasing the muscular effort tenfold and of being very oriented.

Patent WO/2020/212270 entitled "hybrid muscular/electrical training system", filed by "ELLIOPI" on April 09, 2020 and published on October 22, 2020 relates to a fixed, portable or mobile muscular/electrical hybrid training system comprising a converter of muscular energy into rotary energy coupled to a kinematic chain comprising an electric generator and a flywheel. The generator supplying a current to an energy management circuit controlling the recharging of an electric storage means and supplying it with an electric motor. Said muscular energy converter also drives a second electric generator with a power lower than the power of said main electric generator supplying an electric current to said energy management circuit, to ensure degraded operation of said system. However, this invention does not increase muscle energy tenfold and simply appears as a self-sustaining generator.

The present invention aims to design a motor whose operation is independent of fossil fuels and the electrical network or any other form of energy production and intended for driving all types of mechanical equipment.

In accordance with the invention, this object is achieved with the pedestrian or manual pedal motor which multiplies n times such that n 2:10, the torque and the speed of a slow rotational movement from a weak muscular effort carried out by an operator. It is a device made up of several organs whose number and dimensions depend on the power to be deployed and which are in interactive rotational movement with the role of transmitting a slow rotational movement by multiplying its torque and its speed of rotation by staged variations. It is intended to drive any mechanical device (grinder, pump, crusher,

[4] dynamo, threshing machine) or to be taken on board an electric vehicle to quickly recharge the battery in the event of energy distress in an area without a public recharging terminal.

In one embodiment, the invention generally comprises a main toothed wheel moved by an eccentric pedal and two other toothed wheels, each comprising a pulley in its central axis. Two other independent eccentric pulleys, connected by transmission belts or chains to the wheels make up the system in accordance with the invention, as well as a saddle for the operator or pedal motor and a fixed support serving as a hand rest.

In its operation, the main attack cogwheel is moved by an off-center pedal, operated with weak muscular force. The movement of the main drive wheel is then transmitted by transmission belts or chains to the main energy transfer wheel via a main reduction pulley with two grooves.

Thus, the energy transfer wheel, via a secondary reduction pulley, located in its central axis, in turn drives an auxiliary reduction pulley located in the central axis of the weighted decoupling wheel. The latter, during its rotational movement therefore drives the weighted decoupling wheel. Finally, the weighted decoupling wheel drives in its rotation movement an attack rotor thanks to a chain or a belt, to which it transmits a rapid rotation movement by means of an output pulley.

The output pulley-attack rotor system constitutes the member for transmitting the tenfold rotational movement of the motor according to the invention. It drives a mechanical device that has been coupled to it via a belt or transmission chain. It can be a dynamo for the production of electric current to recharge a battery, a grinder, a thresher, a sheller, a crusher, a pump and any other related device .

In another embodiment, the pedal motor according to the invention can be modulated to constitute a gear box in wet hold, on board, to equip and drive a light vehicle (bicycle, tricycle or quadricycle) or heavy machinery. In this case, the pedal motor according to the invention is equipped with a clutch located on the drive shaft,

[5] to isolate the transmission and an electric motor powered by a battery recharged by an alternator, whose role is to overcome the forces of inertia when starting the vehicle.

In this embodiment, the pinions and the crowns replace the toothed and weighted wheels and interact to multiply the rotational movement and the invention can be embarked in an electric vehicle in which it makes it possible to recharge in emergency, quickly and punctually the battery, in fifteen minutes (15 min) maximum, in the event of energy distress in an area without a public charging terminal.

Whatever the embodiment, several pedal motors according to the invention mounted in juxtaposed multiple series assembly can drive a coaxial shaft for the implementation of heavy machinery.

The pedal motor or pedal motor according to the invention has many advantages which are as follows:

- it can be used to produce electrical energy, by recharging a battery or an accumulator;

- it has a very good efficiency, it is five times faster in charge than solar energy, it is also ecological and totally independent of fossil fuels;

- it makes it possible to considerably reduce the costs of factors linked to the production and consumption of energy by inducing substantial savings ranging from 50 to 90% on purchase, on spare parts and downtime, on maintenance costs, and on short-term operation;

- its exploitation generates a new profession, that of motor-pedal driver.

- Figure 1 is a front view of a longitudinal section showing the mechanical assemblies;

- Figure 2 is a front view of a longitudinal section representing the equipment coupled to 2 grinders mounted in series as an example:
