1 is a side view showing a main part of a bicycle A with an electric function according to the present invention, in which 1 is a frame of the bicycle A, 2 is a front wheel, 3 is a rear wheel, 4 is a saddle, 5 Is a handle, 6 is a crankshaft, 7 is a crank arm, 8 is a pedal, 9 is a crank gear, 10 is a rear axle of the rear wheel 3, and 1 is a rear wheel.
Reference numeral 1 is a sprocket provided on the rear axle 10, and 12 is a chain wound between a crank gear 9 and a sprocket 11. Then, when the bicycle A is driven by stepping on the pedal 8, the torque (hereinafter referred to as the stepping torque) due to the pedaling force of the pedal 8 is transmitted from the crank gear 9 to the rear wheel 3 via the chain 12, and the bicycle A runs.

(Running by pedaling force) FIG. 2 is a sectional view showing the structure of the crankshaft portion of the bicycle A, FIG. 3 (a) is a sectional view taken along line XX of FIG. 2, and FIG. 3 (b) is of FIG. It is a partially broken Y arrow view. The crankshaft 6 has a bearing (not shown) on a hanger pipe (not shown) of the frame 1.
As shown in FIG. 2, the one-way inner boss 13 is fixed to the crankshaft 6, and the outer turbos 14 arranged on the outer peripheral portion of the inner boss 13 is rotatably supported via the crankshaft 6. The inner boss 13 and the outer turbo 14 are engaged in only one direction by a latch mechanism. That is, as shown in FIG. 3 (a), the latch claws 15 pivotally attached to the outer peripheral portion of the inner boss 13 are engaged with the engaging grooves 16 provided on the inner peripheral surface of the outer turbos 14, and Only the torque in the stepping direction of 8 is transmitted from the inner boss 13 to the outer turbo 14. When the crankshaft 6 rotates in the opposite direction or the rotation of the inner boss 13 is slower than the rotation of the outer turbo 14, the engagement of the latch claw 15 is disengaged, and the inner boss 13 or the pedal 8 idles.

A planetary gear 18 is rotatably attached to each of a plurality of shaft pins 17 provided on the outer turbo 14. A clutch mechanism 19 is provided on the side opposite to the crank gear 9. Clutch mechanism 19
Is composed of two clutch plates 20 and 21 opposed to each other and rotatably inserted in the crankshaft 6, and a sun gear 22 is projectingly provided at the center of the inner clutch plate 20. It is inserted in a region surrounded by each planet gear 18 and meshes with each planet gear 18. The outer clutch plate 21 includes a stationary portion 23 such as the frame 1 and the protruding portion 2.
4, a spring 25 having a relatively large spring constant is interposed. The outer clutch plate 21 has two clutch plates 2
A coupler 26 for connecting / disconnecting 0 and 21 is attached, and normally, the coupler 26 serves to connect the outer clutch plate 2
1 and the inner clutch plate 20 are connected.

Further, the crank gear 9 is integrally formed with the driven gear part 28 through the tubular connecting portion 27, and the crank gear 9 is not fixed to the crank shaft 6,
The driven gear part 28 and the driven gear part 28 are rotatably mounted on the crankshaft 6. A bevel gear 29 is provided on the outer peripheral surface of the driven gear part 28, and an internal gear 31 is provided on the inner peripheral surface of the cylindrical portion 30 extending to the outer peripheral side of the outer turbos 14. This internal gear 31
Mesh with each planet gear 18.

Therefore, when the outer clutch plate 21 and the inner clutch plate 20 are integrally connected by the coupler 26, when the outer boss 14 is rotated together with the inner boss 13 by stepping on the pedal 8, the stepping torque is increased. Is added to the clutch mechanism 19, and the inner clutch plate 20 and the outer clutch plate 21 rotate in the direction of arrow B in FIG. 3B. When the outer clutch plate 21 rotates, the spring 25 is compressed, and the clutch mechanism 19 is located at a position where the torque due to the reaction force from the compressed spring 25 and the stepping torque are balanced.
Is stationary. Therefore, step on the pedal 8 and the outer turbo 1
When 4 is rotated, the planet gear 18 revolves around the sun gear 22 while rotating around the shaft pin 17, and the driven gear part 28 meshing with the planet gear 18 rotates accordingly. The rotation of the crank gear 9 is transmitted to the rear wheel 3 via the chain 12, so that the bicycle A runs.

(Structure of Anti-theft Device) The structure and operation of the coupler 26 are shown in FIGS. 4 (a) and 4 (b). The coupler 26 is of a solenoid type and has a yoke 32 having an E-shaped cross section.
Two solenoid type coils 33a and 33b are provided on the inner peripheral portion of, and a moving element 34 made of a permanent magnet is slidably housed in the center. The mover 34 has a length that is approximately half that of the yoke 32, and a coupling pin 35 projects from the end surface. In this coupler 26, the yoke 32 is fixed to the outer clutch plate 21, and the coupling pin 35 faces the through hole 36 of the outer clutch plate 21. Further, the inner clutch plate 20 is provided with a plurality of coupling holes 37 at positions corresponding to the coupling pins 35 over the entire circumference.

However, when the two coils 33a and 33b are excited to have the polarities shown in FIG. 4A, the mover 34 is pushed out from the rear coil 33b and attracted to the front coil 33a. The mover 34 is driven forward. The protruding coupling pin 35 fits into the coupling hole 37 of the inner clutch plate 20, so that both clutch plates 20 and 21 are connected to each other. After this, even if the coils 33a and 33b are demagnetized, the mover 34, which is a permanent magnet, is attracted to the yoke 32 in the first half and holds the clutch mechanism 19 in the engaged state.

On the contrary, the two coils 33a and 33b are shown in FIG.
When excited to have the polarity shown in FIG.
Is extruded from the front coil 33a and the rear coil 3a
Since it is sucked by 3b, the mover 34 is driven backward. Since the connecting pin 35 comes out of the connecting hole 37 of the inner clutch plate 20, the two clutch plates 20, 21 are separated from each other. After that, even if the coils 33a and 33b are demagnetized, the mover 34, which is a permanent magnet, is attracted to the yoke 32 in the latter half of the part and maintains the disengaged state of the clutch mechanism 19.

However, when the outer clutch plate 21 and the inner clutch plate 20 of the clutch mechanism 19 are disengaged, even if the outer turbo 14 is rotated by stepping on the pedal 8, the crank gear 9 is not loaded. Therefore, the driven gear component 28 does not rotate. Therefore, the planetary gear 18 revolves while meshing with the internal gear 31, and rotates the sun gear 22. Since it is separated from the inner clutch plate 20, it rotates freely and the pedal 8 spins freely.
Bicycle A cannot run. Therefore, the clutch mechanism 19 constitutes an antitheft device that disables the bicycle A to travel.

The anti-theft device may have any structure other than the device for making the bicycle A unable to run by making the pedal 8 idle as described above. For example, as generally used, the front wheel 2 is locked so that it cannot rotate, the rear wheel 3 is locked so that it cannot rotate, and the pedal 8 is locked so that it cannot be stepped on. But it is okay. Alternatively, a lock bar used for a front wheel portion of a normal bicycle may be moved by an actuator.

(Running by Auxiliary Power) Reference numeral 38 shown in FIG. 2 is a motor which is an auxiliary power and is attached to the chain stay 1a of the frame 1. The motor 38 rotates the bevel gear 40 via the one-way clutch 39. The bevel gear 40 meshes with the bevel gear 29 of the driven gear component 28. Therefore, when the motor 38 is rotated, the motor 38
Power of the crank gear 9 is transmitted to the driven gear part 28.
Is rotated and the rear wheel 3 is driven. Therefore, the rear wheel 3 is driven by the pedaling force, and the pedaling force is assisted by the motor 38, so that the bicycle A can be traveled lightly with a small effort. Further, the one-way clutch 39 prevents the motor 38 from becoming a load when the rotation of the motor 38 is slow. If the reduction gear ratio of the bevel gear 29 and the bevel gear 40 is not appropriate, the motor 38 and the bevel gear 4 are not used.
A speed reducer may be provided between the speed reducer and zero. The method of providing the auxiliary power is not limited to this embodiment, and various structures such as those proposed so far may be used.

(Torque Sensor) A torque sensor 41 is also shown in FIG. Since the pedaling torque of the pedal 8 and the torque of the reaction force of the spring 25 are balanced as described above, the pedaling torque is proportional to the compression amount of the spring 25. Therefore, if the slider 43 of the linear potentiometer 42 is attached to the protrusion 24 of the outer clutch plate 21 as shown in FIG. 3B, the stepping torque can be obtained from the resistance value of the potentiometer 42 (FIG. 5). .

(Torque sensor switch) FIG.
A torque sensor switch 44 including a micro switch is shown in (b). Projection 2 of outer clutch plate 21
4, a torque sensor switch 44 is provided so that when the stepping torque is almost zero, the sensing lever 45 of the torque sensor switch 44 is pushed to turn off the torque sensor switch 44, and the stepping torque is constant. When the value exceeds the value, the protrusion 24 is disengaged from the sensing lever 45 and the torque sensor switch 44 is turned on (FIG. 6).

(Other Example of Torque Sensor) FIG. 7 shows a torque sensor 41 using a rotary potentiometer 46. In the torque sensor 41, the amount of compression of the spring 25 due to the stepping torque is converted into the rotation angle of the rotary lever 47 of the rotary potentiometer 46, and the magnitude of the stepping torque is detected from the change in the resistance value of the potentiometer 46 accordingly. Further, when the sensing lever 45 of the torque sensor switch 44 is also brought into contact with the concave portion 48 of the rotary lever 47 and the stepping torque is applied to remove the sensing lever 45 from the concave portion 48 of the rotary lever 47, the torque sensor switch 4
4 is turned on.

(Speed Sensor) The speed sensor 49 of the bicycle A is, for example, a crank gear 9 as shown in FIG.
A tooth (pulsaring portion) 50 provided at a constant pitch on the outer peripheral surface of the tubular connecting portion 27 integrated with the tooth, and the tooth 50.
Sensor and non-contact type Hall IC that are placed facing each other
The detector 51 includes a sensor and the like. Then, the traveling speed of the bicycle A is calculated from the number of teeth detected by the detector 51 per unit time. The traveling speed of the bicycle A thus obtained is displayed on the display portion 53 of the speedometer 52 as shown in FIG.

(Generator) Reference numeral 54 in FIG. 1 is a hub generator provided on the front wheel 2. A secondary battery 55 is provided on the bottom surface of the basket 56 and serves as a power source for the auxiliary power motor 38, the keyless system, and the like. The electric power generated by the hub generator 54 while the bicycle A is traveling is charged in the secondary battery 55. The motor 38 may not be provided with the one-way clutch 39, and when the stepping torque is applied to the motor 38, the motor 38 may serve as a generator to charge the secondary battery 55.

Therefore, by partially charging the electric power generated by pedaling the pedal 8 while the bicycle A is in operation, the electric power that must be secured on the side of the bicycle A is the ID code for several times. The electric power for driving the clutch mechanism 19 is sufficient if the electric power for driving and the ID code match.

(Warning Means) Further, the speedometer 52 is provided with an alarm device 57 such as a buzzer. Although a buzzer is shown as the alarm 57 in FIG. 9, a lamp or the like may be provided.

(Structure of Keyless System) FIG. 10 is a view showing a keyless system for a bicycle with an electric assist function, in which 61 is a card type key (transmitting means) carried by the owner of the bicycle A, and 62 is It is a control box (reception means) attached to the bicycle A. Control box 62
Is preferably attached to a position where the key 61 can be inserted in a comfortable posture, and may be provided near the handle 5 as shown in FIG. 1, for example.

The key 61 is such that a circuit module 64 as shown in FIGS. 11 and 12 is housed in a case 63. 65 is a circuit board, 66 is a battery, 67 is a CPU, 6

The light emitting element 69 such as a light emitting diode (LED) and the permanent magnet 70 are arranged on the center line of the circuit board 65, and the pair of reed switches 71a and 71b are provided in the light emitting element 6.
They are arranged at symmetrical positions with 9 in between. Light emitting element 69
Is a double-sided light emitting type, and emits infrared rays to both sides through the opening 72 of the circuit board 65. Of course, individual light emitting elements may be attached to both surfaces of the circuit board 65. Corresponding to the light emitting element 69 of the double-sided light emitting type, the whole or a part of both surfaces of the case 63 (at least a portion facing the light emitting element 69) is formed of an infrared transmitting material.

The circuit configuration of the circuit module 64 in the key 61 is shown in FIG. 13 and its operation is shown in FIG. Reference numeral 69a in the figure denotes a transistor for driving a light emitting element. Normally, the base of the transistor 69a is controlled to a high potential and the transistor 69a is off, so the light emitting element 69 does not emit light. Here, when either of the reed switches 71a or 71b is turned on (S9
1) When the key 61 is activated, the CPU 67 reads the ID code stored in the memory 68 (S92), and determines whether the key switch is turned on (S93, S97) and turns it on. The driving mode signal (power mode signal P / economy mode signal E) corresponding to the reed switch 71a / 71b being turned on is read (S9).
4, S98). Next, by controlling the base potential of the transistor 69a, the ID code and its running mode signal as shown in FIG. 14 are transmitted from the light emitting element 69 (S95, S99). When the reed switch 71a / 71b which has been turned on is turned off, the transmission of the ID code and the traveling mode signal is stopped (S96, S100).

Here, since the ID code and the traveling mode signal are transmitted and received by infrared rays without using radio waves, there is no fear of eavesdropping and the safety is high.

To release the anti-theft device of the bicycle A, the key 61 is inserted into the key insertion hole 73 of the control box 62.
As shown in FIG. 16, the control box 62 is provided with a light receiving element 74 at a position facing the light emitting element 69 of the key 61 and a lead at a position facing the permanent magnet 70 of the key 61 when the key 61 is inserted. A switch 75 is provided, and a permanent magnet 76 is provided at a position facing either one of the reed switches 71a and 71b of the key 61. When the key 61 is inserted into the key insertion hole 73 of the control box 62, the permanent magnet 70 of the key 61 and the reed switch 75 of the control box 62 face each other as shown in FIG. The magnetic field is actuated to close the reed switch 75 of the control box 62, and the control box 62 enters the reception standby state. The light emitting element 69 of the key 61 and the light receiving element 74 of the control box 62 also face each other. Further, as shown in FIG. 17B, the permanent magnet 76 of the control box 62 faces one of the reed switches 71a / 71b of the key 61. Therefore, the reed switch 71a / 71b on the side facing the permanent magnet 76
Turns on, which of the reed switches 71a / 71b
When is turned on, it is set to economy mode or power mode.

FIG. 18 shows the circuit configuration of the control box 62. Reference numeral 101 is a battery, 102 is a power supply circuit, 103 is a switching transistor for connecting / disconnecting the battery 101 and the power supply circuit 102, and 104 is an electrolytic capacitor. Then, when the reed switch 75 and the torque sensor switch 44 are off, the switching transistor 103 is kept off, so that the power supply circuit 102 is also kept off and power is not consumed. On the other hand, when the reed switch 75 is turned on, the switching transistor 103 is turned on and the power supply circuit 102 is also turned on.
Power is supplied to U105. Torque sensor switch 4
Even when the No. 4 is turned on, the power supply circuit 102 is also turned on and the power is supplied to the CPU 105.

When the power supply circuit 102 is turned on, the CPU 10
When power is supplied to 5, the light receiving element 74 receives the ID code from the light emitting element 69 of the key 61, and the CPU 105 collates it with the ID code registered in the memory 111.

The battery 101 is connected to the motor switch 108, the motor 38, the FET (field effect transistor) 109, and the shunt resistor 110. Normally, the motor switch 108 is open and the motor 38 is stopped. . However, when the ID codes received by the light receiving element 74 match, the signal output from the CPU 105 is amplified by the amplifier circuit 106 and then drives the power relay 107 to close the motor switch 108. Therefore, the motor 3
8 can be used for driving assistance. The motor torque is controlled by controlling the gate potential of the FET 109 and adjusting the motor current according to the stepping torque detected by the torque sensor 41 and the traveling speed detected by the speed sensor 49. When the ID codes match, the solenoid drive circuit 112 is driven,

U105 detects the electric current for controlling the electric power supplied to the motor 38, for setting the electric current value according to the torque, and in the economy mode etc., the relation between the electric current value and the torque is shown. It is for changing.

(Explanation of Keyless System Operation) FIG.
6 is a block diagram showing the operation of the control box 62. FIG. When the key 61 is not inserted, the power supply circuit 1
02 is off and the control box 62 does not consume power. When the key 61 is inserted, the ID codes are collated, and if they match, the anti-theft device is released as described below to enable traveling. After the anti-theft device is released, even if the key 61 is removed from the control box 62, the anti-theft device is maintained in the released state unless the anti-theft switch 77 is pressed.
When the anti-theft switch 77 is pressed, the anti-theft device is activated and the vehicle cannot run.

That is, when the key 61 is inserted into the key insertion hole 73 of the control box 62, the permanent magnet 7 of the key 61 is inserted.
The reed switch 75 is turned on by 0 (S12
1). When the reed switch 75 is turned on, the switching transistor 103 is turned on and the power supply circuit 102 is turned on (S122). When the power supply circuit 102 is turned on,
The control box 62 enters a light receiving standby state (S123).
When the light receiving element 74 receives the ID code and the traveling mode signal as shown in FIG. 14 transmitted from the light emitting element 69 of the key 61, the CPU 105 stores the ID stored in the memory 111.
Collate with the code (S124, S125). At this time,
If the ID codes do not match, the clutch mechanism 19 is disengaged (the anti-theft device is activated) to disable traveling (S12).
7), the power supply circuit 102 is turned off (S147).

On the other hand, if the ID codes match, the clutch mechanism 19 is brought into the engaged state (release of the antitheft device). Therefore, the bicycle A is ready to run (S126).
At this time, the alarm 57 such as a buzzer is activated.

Then, the motor switch 108 is closed to allow the motor 38 to rotate and the traveling assist function can be used (S128). The power mode or the economy mode is determined by the traveling mode signal received by the light receiving element 74 (S129), and the control mode of the CPU 105 is set to the traveling assist mode of the determination result (S130, S14).
1). Therefore, when the bicycle A is run, the load of stepping on the pedal 8 according to the set running assist mode is reduced. Then, as long as the anti-theft switch 77 is not pressed, the bicycle A can be driven while using the traveling assist function.

When the bicycle A is stopped and the anti-theft switch 77 is pressed (S140, S142), an alarm device such as a buzzer is activated (S143), and after a predetermined time has elapsed (S144),
The motor switch 108 is turned off (S145), the anti-theft device is activated to disable traveling (S146), and the power supply circuit 1
02 is turned off (S147).

When the anti-theft switch 77 is pressed here, the bicycle A is made unable to run after the alarm 57 is activated. If the anti-theft switch 77 is accidentally touched during running, it suddenly becomes impossible to run. Since it is dangerous (especially, it is very dangerous when the wheels are locked so that the vehicle cannot run), the vehicle is disabled after being notified by a buzzer or the like. Further, in order to avoid such a danger, even if the anti-theft switch 77 is pressed, the anti-theft device does not prevent the vehicle from traveling during traveling, and the traveling speed detected by the speed sensor 49 when the bicycle A is stopped is zero. When it becomes, the anti-theft device may be activated so that the vehicle cannot run.

The alarm 57 can be operated in various modes. For example, when the bicycle A is parked in a state where the bicycle A cannot be driven by operating the anti-theft device, if the user tries to move the vehicle by pushing the pedal 8 or pushing the bicycle A, the torque sensor switch 44 turns on. Then, the alarm 57 such as a buzzer can be activated. For this purpose, in the case of the antitheft device of the type in which the pedal 8 runs idle and the bicycle A cannot run as shown in FIG. 2, for example, the boss of the inner clutch plate 20 and the boss of the outer clutch plate 21 are the same. If a small frictional force can be transmitted between the inner clutch plate 20 and the outer clutch plate 21 by means such as press contact, when the inner clutch plate 20 rotates by pedaling the pedal 8 or pushing the bicycle A. By friction (because a large frictional force cannot be transmitted, the pedal A cannot be pedaled to drive the bicycle A). The outer clutch plate 2
The torque sensor switch 44 may be turned on by rotating 1 slightly. When the torque sensor switch 44 is turned on, the switching transistor 103 is turned on, the power supply circuit 102 is turned on, and the alarm 57 such as a buzzer operates.

Further, in the antitheft device of the type that locks the front wheels 2 or the rear wheels 3 and the like to prevent them from rotating, the lock mechanism is provided with play so that the crank gear 9 can rotate to some extent. If so, the torque sensor switch 4 is moved when the pedal 8 is moved or the bicycle A is moved.
4 can be turned on to activate the alarm 57 such as a buzzer.

By thus activating the alarm 57, the antitheft effect of the bicycle A can be enhanced. In particular, when the bicycle A can be pushed and moved like the antitheft device of the type in which the pedal 8 idles as shown in FIG. The significance of having it is great.

Even if the key 61 is inserted into the control box 62, the ID codes do not match, and the torque sensor 4
1 or when the torque is detected a plurality of times by the torque sensor switch 44, an alarm may be issued as an abnormality.

As a usage pattern of the keyless system, a method other than the above is possible. For example, the anti-theft device can be released only while the key 61 is inserted into the key insertion hole 73 of the control box 62. However, in that case, the key 61 may be pulled out of the control box 62 and stolen. Further, during that time, the key 61 and the control box 62 continue to consume power for transmission and reception.

Therefore, the key 61 is inserted into the control box 62 only when the anti-theft device is released and when the anti-theft device is operated, that is, when the bicycle A is getting on and off, and while the bicycle A is driving or when the bicycle is parked, the key 61 is inserted. It is preferable to store 61 in a pocket or the like. However, when the antitheft device is activated to make the vehicle incapable of traveling, collation of the ID code is unnecessary. Therefore, only when the bicycle A is run with the anti-theft device released as described above, the key 61
If you want to make it impossible to run bicycle A after getting off the bicycle,
It is most convenient to press the anti-theft switch 77 to activate the anti-theft device.

The anti-theft switch 77 and the alarm 57 may be provided in the control box 62.

(Explanation of Driving Assist Function) Various methods have been proposed in the past as a driving assist function for assisting the traveling of a bicycle by using the motor 38 and performing a light traveling. You can use the method. For example, an assist method as described below can be used.

The torque generated by the motor 38 (hereinafter referred to as "motor torque") is controlled according to the pedaling torque detected by the torque sensor 41 (pedal pedaling force by human power) and the traveling speed detected by the speed sensor 49. To be done. That is, regarding the relationship between the motor torque (motor current) and the stepping torque, as shown in FIG. 20, when the stepping torque exceeds a certain value, the motor torque is generated and the motor torque linearly increases according to the stepping torque. However, when the limit value is reached, it is kept constant. Here, when the traveling assist mode is set to the power mode, the ratio of the motor torque and the stepping torque (motor torque / motor torque /
When the economy mode is set, the motor torque / stepping torque has a small control characteristic.

FIG. 21 shows the relationship between the motor torque and the traveling speed. The running speed is controlled so that the motor torque / stepping torque is constant up to a constant speed V1, the motor torque / stepping torque is gradually reduced in V1 and V2, and the motor torque is set to 0 (stepping torque 100% when V2 or more). ). Therefore, the motor torque works at a large ratio when starting or traveling uphill so that the vehicle can travel lightly, but when traveling downhill, it travels only with the stepping torque.
