Description

hybrid muscular/electric training system

Field of invention

The present invention relates to the field of fixed, portable or mobile muscular/electric hybrid drive systems, for driving or moving a load or for locomotion, in particular for a cycle, in particular an electric bicycle.

It is usual to provide hybrid systems for the implementation of mechanical energy structurally associated with dynamo-electric machines, with a flywheel to smooth the forces.

These hybrid systems are used to drive a load, for example an electric generator to produce domestic electricity, or to move a load, for example a bucket to draw water from a well.

An adult person without special training is able to deliver 100 to 200 watts easily for a few hours, and with average training can deliver up to 300 watts of power.

Electric-assisted bicycles are very popular today. The motorization of an electric bicycle consists of a motor, a battery and a control circuit.

The motor allows the cyclist to feel supported in his pedaling effort.

There are several types of engines:

• Front wheel motor located in the hub of the front wheel providing linear assistance because the drive is directly on the wheel.
• Rear wheel motor located in the rear wheel hub.
• Pedal motor acting on the crank axle.

The power required to move the bicycle is a function of parameters such as on-board load and speed, and of environmental variables (slope of the traffic lane, relative wind) and can therefore vary greatly from negative values downhill to 'at large positive values on the way up.

On the other hand, the cyclist provides his best effort by maintaining a constant speed and torque. This is the reason why elaborate kinematic chains have been proposed in the state of the art including a flywheel to smooth the forces.

State of the art

We know in the state of the art the Chinese utility model CN203427955 describing a bicycle with a flywheel associated with a device for recharging the energy of a battery during a descent.

The device includes a clutch controlling the activation of the battery recharge. When the bike is uphill or on flat ground, the device is disengaged to reduce the load.

The international patent application WO2015039529 describes a device for recharging a battery by a flywheel. When the bicycle is downhill, the device is automatically engaged to supply kinetic energy to the flywheel; and when the bicycle is uphill or moving on a flat surface, the device is automatically disengaged in order to lighten the power required.

US patent US4768607 describes a freewheel flywheel transmission system capable of storing and releasing rotational kinetic energy, comprising a shaft rotatably supported by a frame and a plurality of flywheels rigidly mounted on the shaft . The transmission system has an input gear for rotating the shaft in response to power transmitted from a power source. A pinion assembly is mounted on the shaft to transmit rotational motion from the flywheels to a drive wheel pinion. In one embodiment, power is supplied to an overrunning pinion which rotates the shaft, and thus to the plurality of flywheels. The pinion assembly includes first and second pinions of different diameters, each rotatably supported on bearings on the shaft. First and second clutches are used to respectively engage the first pinion and a first flywheel of said plurality of flywheels, and the second pinion and a second flywheel, allowing the user to transfer power to the flywheel pinion to operate a vehicle in a plurality of modes according to power requirements.

US6019385 discloses an energy storage device which comprises, in combination: a vehicle suitable for propulsion via power supplied by an operator, the vehicle having a pedal crank and a coaster brake hub disposed around the the axle of a vehicle wheel, the pedal crank and the coaster brake the hub being disposed in operative communication to transmit power from the crank of the crank to the coaster brake hub and then to the wheel; an energy storage device for selectively storing energy and selectively applying the stored energy, the energy storage device being disposed in operative communication with the pedal crank to transmit energy from the crank to the energy storage device for storing energy, and the energy storage device being disposed in operative communication with the coaster brake hub for selectively transmitting stored energy from the energy storage device to the coaster brake hub; and, a combining device for differentially combining the instantaneous energy supplied by the operator and the energy storage device, such that the energy applied to the coaster brake hub is essentially the sum of the instantaneous energy supplied by the operator and the energy storage device.

Disadvantages of the Prior Art

The solutions of the prior art have the drawback of requiring occasional recharging of the battery by connection to a charger. This requires having an electrical source of power and a charger, which is not the case in certain regions not served by the electrical network. This also requires being able to bring the device, for example the bicycle, into the immediate vicinity of the charger to allow connection, or to remove the battery to transport it close to the charger for connection and recharging.

Solution provided by the invention

In order to remedy this drawback, the present invention relates, in its most general sense, to a muscular/electrical hybrid drive system comprising a converter of muscular energy into rotary energy coupled to a kinematic chain comprising an electric generator and a flywheel. inertia, said generator supplying a current to an energy management circuit controlling the recharging of an electric storage means and supplying it with an electric motor, characterized in that 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.

Advantageously, the mechanical coupling between said muscular energy converter and said flywheel comprises a controllable clutch.

The present invention will be better understood on reading the detailed description of a non-limiting example of the invention which follows, with reference to the appended drawings where:

Figure 1 shows a schematic view of the kinematic chain.

FIG. 2 represents an alternative embodiment with a launcher.

FIG. 5 represents another embodiment variant.

General principle of the invention

A crankset or a crank is operated by a human being to drive a multiplier system, which will increase the speed of rotation.

The multiplier system will train via a freewheel:

• a small capacity permanent magnet generator, with low frictional resistance. (The permanent magnet generator is always linked (via the multiplier system) with the human drive. The permanent magnet generator is independent of the flywheel).
• a flywheel (controlled to limit the force to be exerted on the crankset during the start-up/start of rotation phase). The flywheel drives via a clutch, an electromagnet generator.

Upstream, a pilot power manager according to predefined parameters and information received via various sensors:

• management of human effort
• the management of the energy produced according to the needs necessary for operation at "normal power" of the connected electric motor.

The excess energy produced is stored for future use.

Description of the kinematic chain

Figure 1 shows a schematic view of the kinematic chain according to the invention. The human effort is applied via a crankset (1) driving via a multiplier gear train (2) a permanent magnet generator (3) as well as a flywheel ( 4) coupled. A second generator (5) with electromagnet (6) is driven via a clutch (7). The permanent magnet generator (3) is always connected via the multiplier system (2) with the crankset (1). The permanent magnet generator is independent of the flywheel (4) thanks to the clutch (7).

The flywheel (4) can be controlled to limit the force to be exerted on the crankset (1) during the start-up/start of rotation phase. It can consist of a flyweight system moving apart under the effect of centrifugal force to present increasing inertia as a function of speed and automatically adapt the effort provided by the person pedaling.

The electricity produced by the generators (3, 5) powers a motor (7). A power management module (8) manages the electricity produced and consumed and has an electricity storage means (9) for example batteries or supercapacitors.

The power supply manager (8) controls operation according to predefined parameters and information received via various sensors:

• management of human effort
• Management of the energy produced according to the needs necessary for operation at "normal power" of the connected electric motor (7).

The permanent magnet generator (3) also called an alternator consists of an electric machine performing the conversion of mechanical energy into electrical energy, with brushes and rotating commutator or preferably by a polyphase synchronous alternating current machine in which the stator magnetic fields and rotor rotate at the same speed.

In the case of a DC permanent magnet generator, the inductor is located at the stator with an assembly of permanent magnets.

In the case of an alternating current magnet generator, the inductor is located at the rotor with an assembly of permanent magnets.

An alternating current permanent magnet generator has a higher mass and density torque and a higher mass and density power than a direct current generator.

For example, the permanent magnet generator (3) provides a power of 10 watts at 12 volts.

The inertia wheel (4) is a rotating disk, recovering then supplying energy, this energy being stored in the form of kinetic energy of rotation (mass in rotation). It is generally carried out by a hollow wheel, the mass being mainly distributed in a peripheral annular band.

The wound rotor induction electromagnet generator (5) consists of a double-fed asynchronous machine (acronym MADA).

The stator windings are connected to a three-phase motor (7) via the power manager while the rotor windings are connected to bidirectional current power converters: the power passing through these converters can then be absorbed or produced by the machine, depending on the mode of operation.

Asynchronous machines preferably operate at a fixed speed, the rotor speed being almost constant.

Optionally, the system also comprises a renewable energy source (11), for example a turbine or a photovoltaic panel.

The assembly is sealed in the frame of a machine, for example a bicycle, without access to the battery for its removal by the user and without an external charging socket. The battery is not, unlike the battery of electric bicycles, a retractable battery for charging on a charger, but a buffer battery, integrated into the energy management module.

Power Manager

The power manager receives local data from local rotation sensors (10, 40, 70, 71) providing information on the power produced and the power consumed, as well as from a calculation unit (30) provided with a remote communication module (31) with a smart telephone (35), for example by a link with a Bluetooth low energy protocol.

The smart telephone (35) natively has geolocation functions, and the processing and execution of software applications making it possible to communicate with remote resources, for example a computer server transmitting, depending on the instantaneous location, additional information such as geographical forecasts to anticipate future climbs or descents, and thus complete the information from local sensors. Depending on the route taken and thanks to the information transmitted by the navigation system on a smart telephone (35), the energy management module (30) can in particular anticipate the gradients (climbs, descents at short or medium distance) in the calculation of energy optimization.

The energy management module (30) alternatively also receives data such as the diary or the qualification of the departure and destination points, to control the level of human effort, according to the acceptable level of sweating; it can offer superior assistance on a daily basis compared to leisure trips, for example at the weekend (where sweating is less of a problem).

The calculation unit (30) can also receive data from physiological sensors worn by the user, for example a heart rate sensor.

The calculation unit (30) can also include a recharging warning: when returning from vacation or at the end of the weekend and depending on the trip the next day, the system then indicates the number of minutes that it is necessary to pedal for recharge the battery-supercapacitor combo in order to be able to start the next day in good conditions.

Functioning

From the first turn of the pedal and at low rotation speed, the permanent magnet generator stage (3) produces electricity. The electrical production/resistance to mechanical rotation ratio is calculated in such a way as to generate the lowest possible resistance to rotation, while ensuring so-called "minimal" electrical production (power supply of an electric motor in low consumption mode and/or battery charging/hyper capacitors).

If the pedaling speed increases, in fact the speed of rotation of the flywheel also increases, the weights (flywheel) move apart gradually increasing the inertia of the flywheel.

The flywheel stores energy.

Beyond a predetermined rotational speed (at the flywheel output), an electromagnet generator is mechanically engaged gradually.

Once the electromagnet generator has been engaged and after checking the rotational speed of the flywheel (sensor), the electromagnets of the electric generator are excited via an external power supply (battery/capacitor) which is controlled by a manager power supply.

The power manager will (at least) take into account:

• management of human effort (torque exerted on pedal cranks, monitoring of pedal rotation speed)
• management of the energy produced (depending on the energy required for operation at "normal power" of the connected electric motor (energy absorbed, battery/capacitor state, consideration of the torque required: load, resistance to movement, etc..).

The local data is, according to a variant, transmitted by the computer (30) to the smart telephone (35). The latter runs an application that controls the transmission at repeated intervals of a sequence of data comprising geolocation, dating and effort data. This data is aggregated on the server to pool the data from a fleet of equipment, and to transmit to a user the predicted effort data improving the operation of the power supply manager (8).

Human effort management

The resistance to mechanical rotation of the electromagnet generator is proportional to the brake generated by the magnetic field (power consumption, battery/capacitor state, etc.).

If the magnetic brake is very high, the pedaling effort may become "physically" too high for the user, resulting in a slowdown in the rotational speed of the crankset. This slowing down will initially consume the energy stored in the flywheel, the speed of rotation of the flywheel will decrease, which will lead to a cascade reduction in the speed of rotation of the electro-generator. magnets.

If the magnetic brake is important and if the speed of rotation of the flywheel drops too low, restarting the rotation of the crankset will require significant physical effort.

To avoid this, a torque sensor on the crankset (1) and 2 rotational speed sensors (10, 40) constantly send the information collected to the power manager.

If the torque applied to the cranks of the crankset is too high (predetermined value) or if the rotational speed of the crankset is below a predetermined threshold, several possible cases:

First case

The power manager decides to no longer excite the magnets of the electromagnet generator (this is still driven by the flywheel). The lower pedaling effort makes it possible to "relaunch" pedaling, the rotational speed of the flywheel increases again, as soon as the measured rotational speed again reaches the predetermined level, the electromagnets of the generator are at again excited.

Second case

The power manager has decided to no longer excite the magnets of the electromagnet generator (still driven by the flywheel). Despite this, the speed of rotation decreases and/or stabilizes below the predetermined level: the electromagnet generator is disengaged, which will further reduce the force to be exerted on the crankset, two possibilities:

1. If the rotational speed of the crankset (and therefore of the flywheel) increases again, as soon as the measured rotational speed again reaches the predetermined level, the electromagnet generator is gradually engaged. If the rotational speed information sent to the power manager is correct, the generator electromagnets are energized again.
2. If the rotational speed of the crankset (and therefore of the flywheel) continues to decrease, only the permanent magnet generator continues to be activated. After a delay period to be determined, the power manager can decide to switch all the energy-consuming components to standby or eco mode (example: the electric motor used for propulsion switches to eco mode, rotation speed and minimum consumption ).

Third case

If the rotation of the crankset is stopped, the speed of rotation of the flywheel will gradually return to zero, and the weights of the flywheel will return to their initial places as before starting pedaling.

Fleet management

According to a variant of management of a fleet of bicycles (or other machines) according to the invention, the system comprises parking points with mutual connections with intelligent energy management. The bicycles (or other machines) are all connected to each other and to a system of solar panels. The management system makes it possible to use the energy of bicycles (or other machines) with a high level of charge to recharge bicycles (or other machines) with a very low level of charge.

Alternatives

Figure 2 represents an alternative for making a hybrid muscular/electric training system equipped with a super capacitor/battery one hundred percent autonomous in all circumstances.

For this purpose, the system comprises a second additional muscle energy converter (100). This muscle energy converter can be the result of:

• a rotation (e.g. a crankset, a pulley)
• and/or an oscillation (e.g. lever, oar)
• and/or a rectilinear translation (e.g. mobile seat of a rower/oar). It is mechanically coupled to the muscular/electric hybrid drive system.

It provides for the use of a manual "launcher" (100) (pulley + rope type) or lever or foot type (starter pedal type) or even by rectilinear displacement mechanically coupled to the hybrid muscular/ electric.

Variant “Pulley type launcher + rope”

FIG. 2 represents an alternative embodiment with a launcher (100) comprising:

• a pulley (101) on which a rope (102) is wound. At the end of the rope is fixed a handle (103) which makes it possible to comfortably pull on the rope for launching.
• two snail springs (104, 105): one provides rewinding and the other rotation assistance
• A gear relay train
• A pawl clutch (106), having two functions: uncoupling the crankset (no rotation possible when the starter is engaged) and engaging the pulley.

Operation in the bicycle example:

The user keeps the bike upright either by sitting on it, or by standing beside it and holding the bike with one hand.

By activating the launcher, a cord (101) is pulled which will cause the rotation of the pulley and compress (tighten) the two springs (104, 105), once the cord (101) has been fully unwound, the handle (102) of the launcher is returned to its initial position (helped in this by the spring (104) which performs the rewind function). The rotation assistance spring (105) is released which will cause the rotation of the hybrid assistance generator. The operation is repeated as many times as necessary to maintain an adequate speed of rotation of the flywheel and thus ensure energy production (see description of the operation of the hybrid muscular/electric drive system).

The energy produced is stored via the power manager in the super capacitor/battery.

When the level of charge is sufficient to supply the electric propulsion motor at a minimum (minimum load to ensure the propulsion of the bicycle at reduced speed over X meters) a visual or audible signal (on the power management console and/or smartphone) warns the user. The launcher is mechanically disengaged by the user.

The user can then straddle his bike and start a rotation of the crankset, the pressure generated on one of the pedals will trigger the electric propulsion assistance. Once the bike is in motion, it is then quite possible to pedal and therefore to generate energy via the muscular/electric hybrid drive system and therefore to generate the energy necessary to move the bike.

Variant "Lever-type launcher"

FIG. 3 represents an alternative embodiment with a lever launcher comprising:

• a lever (200) with a handle (201)
• a toothed sector in conjunction with a pinion relay train
• a ratchet clutch (202), having the function of uncoupling the crankset (no rotation possible when the starter is engaged)
• a second pawl clutch (203) coupled to an inverter pinion, ensuring the clutch of the lever in the 2 directions of oscillation.

The lever (200) oscillates on its axis (over an amplitude of at least 120°). This oscillation is transformed into rotation via a notched sector + gear relay train. A ratchet clutch system (+ pinion) makes it possible to ensure that, whatever the direction of the oscillation (forwards or backwards), the oscillation of the lever is transformed into rotation.

Operation in the bicycle example:

The user keeps the bike upright either by sitting on it, or by standing beside it and holding the bike with one hand.

By oscillating the lever back and forth and back and forth (from end of stroke to end of stroke, i.e. at least an amplitude of around 120°). Each oscillation of the lever goes via a notched sector and a pinion relay train to cause the rotation of the muscular/electric hybrid drive system.

This back-and-forth operation is repeated as many times as necessary to maintain an adequate speed of rotation of the flywheel and thus ensure energy production (see description of the operation of the hybrid muscular/electric drive system) .

The energy produced is stored via the power manager in the super capacitor/battery combo.

When the level of charge is sufficient to supply the electric propulsion motor at a minimum (minimum load to ensure the propulsion of the bicycle at reduced speed over X meters) a visual or audible signal (on the power management console and/or smartphone) warns the user. The launcher is mechanically disengaged by the user.

The user can then straddle his bike and start a rotation of the crankset, the pressure generated on one of the pedals will trigger the electric propulsion assistance. Once the bike is in motion, it is then quite possible to pedal and therefore to generate energy via the muscular/electric hybrid drive system and therefore to generate the energy necessary to move the bike.

Variant "starter pedal type launcher"

FIG. 4 represents a variant embodiment with a launcher using:

• the crankset (1) of the muscular/electric hybrid drive system
• a selector/push-button (300) which makes it possible to couple the launcher to the crankset and to select the right or left pedal which will be used
• two snail springs (301, 302): one ensures the return of the selected pedal, the other spring provides rotation assistance
• a set of gears to obtain a ratio of approximately 1/10 at the exit of the launcher
• a mechanical coupling (by push button/joystick) to the axis of the hybrid assistance generator
• pawls providing the clutch.

One of the 2 pedals is used, the right or the left depending on the user's preferences or call foot.

Operation in the bicycle example:

The user keeps the bike upright either by sitting on it, or by standing beside it and holding the bike with one hand.

By pressing the push button, the launcher is coupled to the pedal, one of the two pedals is selected. The selected pedal is returned to its highest position by the return spring. Pressing the pedal and rotating it 180° downwards, the output shaft of the pinion train makes about 5 turns, the operation is repeated a second time, to tension the assistance spring to its maximum. Once this spring is tensioned, the spring is automatically released and via the ratchet clutch drives the hybrid muscle/electric drive system.

By releasing the pressure on the pedal, it is raised upwards (by the return spring) to its initial position. By pressing the pedal again, the cycle is repeated, it is repeated as many times as necessary to maintain an adequate speed of rotation of the flywheel and thus ensure energy production (see description of the operation of the system of hybrid muscular/electric training).

The energy produced is stored via the power manager in the super capacitor/battery combo.

When the level of charge is sufficient to supply the electric propulsion motor at a minimum (minimum load to ensure the propulsion of the bicycle at reduced speed over X meters) a visual or audible signal (on the power management console and/or smartphone) warns the user. The launcher is mechanically disengaged by the user.

The user can then straddle his bike and start a rotation of the crankset, the pressure generated on one of the pedals will trigger the electric propulsion assistance. Once the bike is in motion, it is then quite possible to pedal and therefore to generate energy via the muscular/electric hybrid drive system and therefore to generate the energy necessary to move the bike.

Variant "Launcher by rectilinear movement"

Principle:

The rectilinear translation of an object is transformed into energy, example of application for a handle (401, 402) sliding along a rail (400):

• a sliding handle (401, 402) along a rail (400), this handle driving a rack (parallel to the rail)
• a rack and pinion connection muscular/electric hybrid drive system by relay train (405) of pinion gear
• a pawl clutch (404) coupled to an inverter pinion, ensuring the clutch in both directions of translation
• a mechanical coupling (by push button/joystick) to the axis of the hybrid muscular/electric drive system hybrid assistance generator
• pawls ensuring the clutch
• a second ratchet clutch, having the function of uncoupling the crankset (no rotation possible when the starter is engaged)
• a return spring (403)

Operation in the example of the bicycle:

The user keeps the bike upright either by sitting on it, or by standing beside it and holding the bike with one hand.

By actuating and sliding the handle back and forth and back and forth (from end of stroke to end of stroke), each translation of the handle goes via the rack and a pinion relay train to cause the rotation of the system. hybrid muscular/electric training. Once at the end of the stroke, the handle is returned to its initial position, releasing the pressure on it.

This back-and-forth operation is repeated as many times as necessary to maintain an adequate speed of rotation of the flywheel and thus ensure energy production (see description of the operation of the hybrid muscular/electric drive system) . The energy produced is stored via the power manager in the super capacitor/battery combo.

When the level of charge is sufficient to supply the electric propulsion motor at a minimum (minimum load to ensure the propulsion of the bicycle at reduced speed over X meters) a visual or audible signal (on the power management console and/or smartphone) warns the user. The launcher is mechanically disengaged by the user.

The user can then straddle his bike and initiate a rotation of the crankset, the pressure generated on one of the pedals will trigger the electric propulsion assistance. Once the bike is in motion, it is then quite possible to pedal and therefore to generate energy via the muscular/electric hybrid drive system and therefore to generate the energy necessary to move the bike.
