Bicycle wheel with alternator wheel motor {Wheel, equipped with wheelmotor combined with a dynamo, for bicycle}

The present invention relates to a wheel for a bicycle equipped with a generator wheel motor, in particular to rotate the rotating shaft around a fixed shaft in which the electric wire is inserted in the center, and the fixed shaft is attached to a plurality of coils at regular intervals on the outer peripheral surface A fixed plate is formed, and the rotating shaft is formed with a rotating plate in which two or more magnets are fixed in contact with the two or more coils, and power generation by the electromotive force generated in the coil is performed according to the rotation of the magnet while the bicycle is rotating. The present invention relates to a bicycle wheel equipped with a generator-driven wheel motor which allows a magnet to rotate smoothly by a coil while reducing the pedal step force while charging the battery or discharging the power charged in the battery.

In general, it is well known that a device that generates rotational force, such as a vehicle or a bicycle, generates electricity using the rotational force to turn on a lamp or use it as a necessary power while charging a charger.

In addition, there is an attempt to use the power charged in the charger as an internal lamp or the like and use it as an auxiliary power source if necessary to increase rotational power.

The conventional auxiliary power device is an engine that is an internal combustion engine,

A generator mechanically connected to the engine to convert mechanical power energy of the engine into electrical energy;

Generator controller for controlling the output of the generator,

Electric motor for generating power to the drive system of the vehicle by receiving the power controlled from the generator controller,

Of the electrical energy generated in the generator of the excess electrical energy is stored and discharged again was composed of storage batteries for supplying the necessary electrical energy.

In addition, the engine is the same as the internal combustion engine of a general gasoline vehicle, and manufactured to be compact to be mounted on a hybrid electric vehicle.

The generator is a permanent magnet generator, the approximate structure of which consists of an armature coil fixedly fixed to a predetermined position of the generator stator, a permanent magnet is installed by the rotor installed so as to be rotated spaced apart from the armature coil for a permanent When the magnet rotor rotates, the electromotive force by Fleming's right hand law is induced between the armature coil and the permanent magnet rotor.

The generator controller is to control the magnitude of the voltage and current, as well as the rectification of the power output in the three-phase AC state when the power is output from the generator when the engine of the internal combustion engine is driven due to the remaining capacity of the battery.

The above-mentioned electric motor is largely divided into a DC motor and an AC motor, and the DC motor uses mechanical switching by a commutator in controlling a magnetic field generated in the stator part, and the upper limit of the number of revolutions is the upper limit of the commercial rotation limit of the internal combustion engine. As it is close, it is suitable for the remodeling of commercial vehicles, and the AC motor has no features of brushless, simple structure, inexpensive and durable. It uses a high magnetic coercive force magnet to make a rotating magnetic field by an inverter. Electric motors of permanent magnet brushless motors can be used, and the upper limit of rotational speed is high because there is no brush, and the coercive force is high, so the electric and force conversion efficiency is high.

Since the drive system has a small output of the electric motor, it secures the necessary power by the transmission like a gasoline car, and adopts a high-power motor to cover the entire speed range without a transmission, thereby reducing the weight and reducing the loss. In addition, an electric motor is mounted in each wheel to achieve high efficiency.

The battery charges the excess current generated by the generator and discharges it when necessary, which is used to connect a plurality of batteries of low voltage capacity in series.

However, according to the conventional auxiliary power device as described above, a generator for generating a current using the rotational force and an electric motor for converting the electric current charged in the battery into the rotational force are configured separately, so that the structure is complicated and the volume is large, such as a car or a bicycle. There was a problem such that the installation area is increased when installed in the device.

The present invention is to solve the problems as described above, as well as to improve the rotational efficiency of the patent application No. 2000-71741 (generator wheel motor) of the applicant of the present applicant, the fixed wire is inserted in the center The rotating shaft is rotated about the axis, and the fixed shaft forms a fixed plate attached with two or more coils at regular intervals on the outer circumferential surface, and the two or more magnets are fixed to the rotating shaft at a position in contact with the two or more coils. As the bicycle rotates, the magnet generates electricity by the electromotive force generated by the coil as the magnet rotates to charge the battery, or the magnet rotates smoothly by the coil while the power is being charged. To provide a bicycle wheel with a generator-driven wheel motor to reduce power .

Bicycle wheel with a generator combined wheel motor of the present invention for achieving the above object is to rotate the rotation axis about the fixed shaft is inserted into the wire through the center hollow,

The fixed shaft is formed with a fixed plate attached to the plurality of coils at least two at regular intervals on the outer peripheral surface,

On the rotating shaft rotated by the pedal of the bicycle to form a rotary plate fixed to the two or more magnets in the position in contact with the two or more coils to generate power by the electromotive force generated in the coil as the magnet rotates while the bicycle is rotating In order to charge a separate battery, while climbing a high place, the magnet is smoothly rotated by the coil while the power charged in the battery is discharged, thereby reducing the pedal step force.

1 and 2 show the overall configuration,

The rotation shaft 6 is rotated about a fixed shaft 1 into which the wire 3 is inserted through the hollow 2 in the center,

The fixed shaft (1) is formed on the outer circumferential surface with a fixed plate (4) attached with a plurality of coils 5 or more at regular intervals,

The rotating shaft 6 which is rotated by a pedal of a bicycle (not shown in the drawing) is formed by forming a rotating plate 7 in which two or more magnets 8 are fixed to a position in contact with the two or more coils 5. will be.

The rotary plate 7 rotates like the wheels 20 when rotated by a pedal (not shown).

3 shows a circuit configuration for the operation of the present invention,

The controller 10 which detects the position and the speed through the Hall sensor 9 provided on one side of the rotating plate 7 in which two or more magnets 8 are attached to the outer circumferential surface of the first motor driver 11 is a transistor. Outputs a control signal to TR1 so that the "S" pole of the magnet 8 of the rotating plate 7 receives the repulsive force of the coil wound in the forward direction, or the control signal to the transistor TR2 of the second motor driver 12. To output the "N" pole of the magnet 8 of the rotating plate 7 to rotate under the repulsive force of the coil wound in the reverse direction,

The two or more coils 5 are coupled in series with coils wound in a forward direction and coils wound in a reverse direction, respectively. When the transistor TR1 is turned on, the two or more coils 5 are wound in the forward and reverse directions by a current applied in the forward direction. The coil 5 causes the rotation force to be generated by the repulsive force in which both the "N" pole and the "S" pole of the magnet 8 are pushed. When the transistor TR2 is turned on, it is reversed by the current applied in the reverse direction. The wound coil 5 causes the "S" and "N" poles of the magnet 8 to be pushed to generate a rotational force,

The controller 10 outputs a control signal to the transistor TR3 of the first power generation driver 13 to produce a coil in which the charging current by the “S” pole of the magnet 8 of the rotating plate 7 is wound in the forward direction. The battery 17 is charged by the charger 16 via the rectifier 15 of the bridge diode BD via the rectifier 15, or by outputting a control signal to the transistor TR4 of the second power generating driver 14, the rotating plate 7 The charging current by the "N" pole of the magnet 8 of the (8) is charged to the battery 17 by the charger 16 via the rectifier 15 of the bridge diode BD via the coil wound in the reverse direction. ,

The controller 10 recognizes a mode in which the rotating plate 7 is rotated by the first and second motor drivers 11 and 12 by the user turning on or off the changeover switch 18. The first and second power generation drivers 13 and 14 allow the battery 17 of the charger 16 to charge the current generated by the rotating plate 7.

The controller 10 allows the current charged in the battery 17 to be normally controlled by the power supplied at the rated voltage through the constant voltage IC 19.

When described in detail the automatic state of the present invention configured as described above,

As the rotating shaft 6 rotates about the fixed shaft 1 which can insert the electric wire 3 through the hollow 2 in the center, it is to generate electric power or generate a rotational force by the magnet and the coil,

The rotating plate 7 attached with a plurality of magnets 8 or more at regular intervals on the outer circumferential surface is rotated like a pedal of a bicycle connected to the rotating shaft 6.

The controller 10 is fixed to the fixed shaft 1 inserted into the rotary shaft 6 through the electric wire 3 while fixing the two or more coils 5 at positions contacting the two or more magnets 8. It is connected to the motor driver 11 (12) or the power generation driver 13 (14) under the control of the electric power so as to charge the current or to obtain the rotational force by the discharge current.

As the user rotates the rotating means including the rotating plate 7 in the forward or reverse direction, the controller 10 detects the position and speed of the rotation through the Hall sensor 9.

In a state in which the rotating means including the rotating plate 7 rotates normally by the user, the user may generate power by rotating force to charge the battery 17 of the charger 16.

That is, at least two magnets 8 are positioned and positioned through the Hall sensor 9 provided between the coil wound in the nth reverse direction of the rotating plate 7 attached to the outer circumferential surface and the coil wound in the first forward direction. The controller 10 for detecting the rotational speed allows the "S" pole or "N" pole of the magnet 8 of the rotating plate 7 to work with the coil wound in the forward direction of the coil 5 or the coil wound in the reverse direction. .

When the “S” pole of the magnet 8 is recognized through the Hall sensor 9 while the rotating plate 7 rotates, the controller 10 is moved from the controller 10 to the transistor TR3 of the first power generation driver 13. The control signal of " L " is output and turned off while the control signal of " H " is output to transistor TR4 of the second power generation driver 14 to be turned on.

In this state, the magnets are firmly attached to the coil 5 so that the polarity thereof is symmetrical, and the two or more magnets 8 having the most force applied to the coil 5 rotate together with the rotating plate 7. Electricity is induced in the coils wound in the forward direction at the “S” pole of 8) so that current is charged to the battery 17 by the charger 16 via the rectifier 15 of the bridge diode BD.

When the "N" pole of the magnet 8 is recognized by the Hall sensor 9 while the rotating plate 7 continues to rotate, the controller 10 of the second generation driver 14 of the second power generation driver 14 is detected by the controller 10. The control signal of "L" is output to be turned off by outputting the control signal of "H" to the transistor TR3 of the first power generation driver 13.

In this state, electricity is induced in coils wound in the reverse direction at the “N” poles of two or more magnets 8 firmly attached so that the polarity of the coil 5 is symmetrical, so that current is bridged diode ( The battery 17 is charged by the charger 16 via the rectifier 15 of the BD.

On the other hand, when the rotating plate 7 reaches the uphill or the rotational force is reduced while rotating the rotational force to improve the torque by the current charged in the battery 17 of the charger (16).

The controller 10 outputs a control signal to the transistor TR1 of the first motor driver 11 or the transistor TR2 of the second motor driver 12 to improve the rotational force of the rotating plate 7.

That is, when the controller 10 recognizes the "S" pole of the magnet 8 through the Hall sensor 9 while the rotating plate 7 rotates, the controller 10 moves to the transistor TR1 of the first motor driver 11. The control signal of "L" is output to be turned on while the control signal of "H" is output to the transistor TR2 of the second motor driver 12 to be turned off.

Therefore, the coils wound in the forward direction by the current through the transistor TR1 of the first motor driver 11 are rotated to induce a repulsive force that pushes the "N" pole of the magnet 8 having a symmetrical polarity. Keep rotating in the direction.

At this time, a repulsive force that pushes the "S" pole of the magnet 8 by the coils wound in the reverse direction to continue to rotate in the direction of rotation.

When the controller 10 recognizes the "N" pole of the magnet 8 through the Hall sensor 9 in the state in which the rotating plate 7 rotates, the transistor 10 of the second motor driver 12 returns to "TR2". While outputting the control signal of "L", the control signal of "H" is output to the transistor TR1 of the first motor driver 11 so as to be turned off so that the direction of current flow is changed.

Therefore, the coils wound in the forward direction are induced by the current flowing in the reverse direction through the transistor TR2 of the second motor driver 12, and the repulsive force that pushes the "S" pole of the magnet 8, which is symmetrical in polarity, acts. Continue to rotate in the direction of rotation.

In addition, the coils wound in the reverse direction are induced, and the repulsive force for pushing the "S" pole of the magnet 8, which is symmetrical in polarity, acts to continue to rotate in the direction of rotation.
