The microcomputer 52 executes a lock control process shown in FIG. In this locking control process, first, in step S1, it is determined whether or not the switch signal SH of the handle lock operation detection switch 15 is on. When the switch signal SH is on, the handle lock device 10 operates the lock key 14 It is determined that the operation has been performed in the locked state, and the process proceeds to step S2.
It is determined whether or not the previous switch signal SH is in the off state. If the previous switch signal SH is in the on state, it is determined that the locked state of the handle lock device 10 is continuing, and the process returns to the step S1 to return to step S1. If there is, it is determined that the operation has been performed from the unlocked state to the locked state, and the process proceeds to step S3.

In this step S3, it is determined whether or not the switch signal of the latch detection switch 41 is on,
This is at an off state, the sliding member 32a of the push latch 32 is in the extended state, swing rod 26A _1, 26
It is determined that the A ₂ and 26B is in the locked state to close back to the step S1 as it is, when in the ON state is determined to be in the unlocked state by opening the swing rod 26A _1, 26A ₂ and 26B To step S4.

In step S4, the A / D converter 51
The battery voltage V _B input from the controller 2 is read, and then the process proceeds to step S5, where the read battery voltage V _B is
8 determines whether a sufficiently drivable set voltage V _BS above, when a V _B ≧ V _BS, it is determined that the battery voltage V _B is sufficient proceeds to step S6, described later After resetting the control state flag FS to “0”, the process proceeds to step S7.

In step S7, a forward rotation drive signal for driving the electric motor 28 to rotate clockwise, for example, is output.
It is determined whether or not the switch signal SC is ON.
When this is off, it is determined that the electric motor 28 is rotating, and the process returns to step S7. When it is on, the process goes to step S9.

In this step S9, it is determined whether or not the switch signal SC of the cam switch 40 at the time of the previous processing is on, and when it is on, it is determined that the electric motor 28 has just been started. Returning to step S7, when it is in the off state, it is determined that the cam 29 has made one rotation and has returned to the predetermined stop position, and the flow shifts to step S10 to stop the output of the motor drive signal, and then shifts to step S11. As shown in FIG. 8B, the buzzer drive signal and the light-emitting diode drive signal that are continuous twice with a relatively short ON state width are transmitted to the buzzer 44 and the light-emitting diode 43.
Then, the process returns to step S1.

The result of the determination in step S5 is V _B
If <V _BS , the process proceeds to step S12 to indicate that the battery voltage is insufficient. For example, as shown in FIG. After outputting a light emitting diode (LED) driving signal to the buzzer 44 and the light emitting diode 43, the process returns to the step S1.

On the other hand, the result of the determination in step S1 is based on the switch signal SH of the steering wheel lock operation detection switch 15.
Is in the off state, the process proceeds to step S13, and it is determined whether or not the previous switch signal SH is in the off state. When the switch signal SH is in the off state, the unlocking state of the handle lock device 10 is assumed to be continued. The process returns to step S1, and if it is in the ON state, it is determined that the unlocking operation has been performed from the locked state of the handle lock device 10, and the process proceeds to step S14.

In this step S14, it is determined whether or not the switch signal SL of the latch detection switch 41 is on. When the switch signal SL is on, the sliding member 32a of the push latch 32 is in the contracted state and swings. Rod 26A _1,
It is determined that the 26A ₂ and 26B are unlocked condition to be opened to return to the step S1, the sliding member 32a is extended state when in the OFF state, swing rod 26A _1, 26A
₂ and 26B are shifted to the step S15 it is determined that the locked state of the closed state, the transition from crowded read the battery voltage V _B that is input from the A / D converter 51 to step S16.

In step S16, the battery voltage V_BBut
Set voltage V described above_BSIt is determined whether or not V_B
≧ V_BS, The battery voltage V_BIs determined to be sufficient
Then, the process proceeds to step S17 to determine whether the unlocking operation has been performed.
Indicates that the unlock operation has been performed.
After setting to “1”, the process proceeds to step S21, _B
<V_BSIf it is, the process proceeds to step S18.

In step S18, as in step S12, the buzzer 44 and the light emitting diode 43
8C, the driving signal shown in FIG. 8C indicating the shortage of the battery voltage is output, and the process proceeds to step S19, where the state flag F
It is determined whether S is set to "1" or not, and if it is set to "1", a step S described later is performed.
The process jumps to step S25, and if the flag has been reset to "0", the flow shifts to step S20 to set the status flag FS to "1", and then shifts to step S21.

In step S21, a forward rotation drive signal is output to the electric motor 28 in the same manner as in step S7, and the process proceeds to step S22 to determine whether the switch signal SC of the cam switch 40 is on. If the switch signal SC is in the ON state, it is determined that the electric motor 28 is rotating, and the process returns to step S21. If the switch is in the ON state, the process proceeds to step S23. If it is in the on state, it is determined that the rotation of the cam plate 29 is in the initial rotation state, and the process returns to step S21. If it is in the off state, the cam plate 29 makes one rotation to reach the predetermined stop position. It is determined that it has returned, and the process proceeds to step S24, in which the output of the drive signal to the electric motor 28 is stopped, and then proceeds to step S25.

In this step S25, it is determined whether or not the switch signal SK of the unlock detection switch 42 is on. When the switch signal SK is off, it is determined that some abnormality has occurred instead of the unlocking state. And step S
Then, as shown in FIG. 8D, the buzzer drive signal and the light-emitting diode drive signal that continue to be in the on state while the abnormal state is continued are output to the buzzer 44 and the light-emitting diode 43 as shown in FIG. Returning to step S1, if the switch signal SK is on, the process proceeds to step S27.
To the switch signal S of the latch detection switch 41.
It is determined whether or not L is in the on state. If it is in the off state, it is determined that the sliding member 32a of the push latch 32 is in the extended state and is in the abnormal state indicating the locked state, and the process proceeds to step S26. Transition and switch signal SL
Is in the ON state, it is determined that the sliding member 32a is in the contracted state and represents the unlocked state, and step S2 is performed.
8, the unlocking buzzer driving signal and the light emitting diode driving signal having a relatively short ON state width are output to the buzzer 44 and the light emitting diode 43 as shown in FIG. Return.

In addition, in the microcomputer 52,
The voltage of the core wire 46c for disconnection detection is monitored, and when this voltage becomes "0" or near it, it is determined that the theft has occurred, and the locking control process of FIG. While maintaining the locked state, the buzzer 44 and the light emitting diode 43 output the continuous buzzer drive signal and the light emitting diode drive signal shown in FIG.

Next, the operation of the above embodiment will be described.
Now, the bicycle 1 is parked, and the handle lock device 1
0 lock key 14 is in the locked position and the stopper 13
Are engaged with the lock gear 12 so that the rotation of the front fork 4 is prohibited, and the curved rod portion 26f of the swinging rod 26B of the rear wheel lock device 20 is moved to the rear wheel 6 as shown in FIG.
Swing rod 26A _1, 26A in between adjacent spokes 8
It is assumed that the spoke 8 is in a locked state in which the spoke 8 is prevented from passing by being inserted between the _two curved rod portions 26c.

In this state, the processing of FIG. 7 has been executed, and since the handle lock device 10 is in the locked state, the switch signal SH of the handle lock operation detection switch 15 is output.
Is in the ON state, and the switch signal SH
Is in the ON state, steps S1 and S2 are repeated, the locking operation and the unlocking operation are not performed, and the locked state of the rear wheel lock device 20 is continued.

From this state, in order for the rider to run the bicycle 1, the cylinder lock 13 of the handle lock device 10 is used.
When the lock key 14 is inserted into the lock gear 11 and then turned to the unlock position, the stopper 12 is released from the lock gear 11 so that the handle 5 can be operated, and at the same time, the handle lock operation detection switch 15 is turned off. In the lock control process of step S7, the process shifts from step S1 to step S13, and since the previous state is the ON state, the process shifts to step S14. Since the rear wheel lock device 20 is in the locked state, the push latch 32
When the sliding member 32a of the
Since the switch signal SL is in the off state, the step S
Step from crowded read the migrated battery voltage V _B to 15 S1
Move to 6.

At this time, if the battery voltage V _B of the primary battery 22 is sufficiently high and is equal to or higher than the set voltage V _BS , the flow shifts to step S17 to reset the state flag FS to “0” and then shifts to step S21. Then, the electric motor 28 is driven forward. At this time, since the cam plate 29 comes into contact with the cam detection switch 40 and the switch signal SC is in the ON state, the process returns to step S7 to continue the normal rotation of the electric motor 28, whereby the cam plate 29 moves clockwise. When rotated and separated from the cam detection switch 41, the cam detection switch 41 is turned off. However, by directly returning from step S8 to step S7, the rotation of the electric motor 28 is continued.

In response, the cam plate 29 rotates forward and its tip engages with the engaging piece 31a of the L-shaped operating rod 31, whereby the L-shaped operating rod 31 rotates counterclockwise. Move
The sliding member 32a of the push latch 32 is pressed by the pressing piece 31b, whereby the locked state of the sliding member 32a at the extended position is released. Accordingly, when the cam plate 29 further rotates forward due to the rotation of the electric motor 28, and the L-shaped operating rod 31 rotates clockwise, the sliding member 32a of the push latch 32 correspondingly moves to the contracted position side. Moving.

[0043] Therefore, stop at its free length position rotated clockwise swing rod 26A _1, 26A ₂ are the elastic force of the return spring 36, similar swing rod 26B is the elastic force of the return spring 37 rotated counterclockwise and stopped at its free length position, curved rod portions of RyoYurado杆26A _1, 26A ₂ and 26B as shown in FIG. 4 26c and 26
f is separated left and right by a predetermined distance, so that the spokes 8 of the rear wheel 6 are unlocked.

Thereafter, when the electric motor 28 further rotates forward and the cam plate 29 rotates clockwise and its tip contacts the cam detection switch 41, the switch signal SC is turned on, and the locking control shown in FIG. In the process, the process proceeds from step S8 to step S9, and since the switch signal SC was in the OFF state until the previous time, the process proceeds to step S10, and the rotation of the electric motor 28 is stopped by stopping the output of the motor drive signal. Accordingly, the rotation of the cam plate 29 is stopped.

When the cam plate 29 is overrunning the cam detection switch 41 at the start of driving of the electric motor 28, the cam detection switch 41 is turned off.
The process moves from step S8 to step S7, and the electric motor 28 can be driven normally. In this manner, the rear wheel lock device 20 is automatically unlocked in response to the unlocking operation of the handle lock device 10, so that even if there are two lock devices on the front wheel side and the rear wheel side, the rider must hold each of them. The trouble of unlocking can be omitted, and a reliable anti-theft effect can be exhibited while reliably preventing annoyance.

When the bicycle is stopped and the bicycle is parked after running the bicycle in the unlocked state, the lock key 1 inserted into the handle lock device 10 is reversed.
When the user rotates the handle 4 to the locked position and then removes it, the stopper 12 engages with the lock gear 11 and the rotation of the handle 5 is locked. At the same time, the switch signal SH of the steering wheel lock operation detection switch 15 is turned on, so in the locking control process of FIG. 7, the process proceeds from step S1 to step S2, and since the previous switch signal SH was in the off state, proceeds to S3, the switch signal SL latch detection switch 41 is in oN state, the process proceeds to step S4, in the same manner as when unlocking described above, with the battery voltage V _B of the primary battery 22 is set voltage V _BS or In some cases, the electric motor 2 is determined in steps S7 to S9.
8 is driven to rotate forward again, whereby the L-shaped operating rod 31 is driven.
Is rotated counterclockwise again, and the sliding member 32a of the push latch 32 is pressed forward, whereby it is extended and held at the extended position. This allows the swinging rod 26A _1, 2
6A ₂ rotates counterclockwise against the return spring 36, and the swinging rod 26B rotates clockwise against the return spring 36, so that these swinging rods 26A
_{When 1,} 26A ₂ and 26B face between the adjacent spokes 8 of the rear wheel 6, the curved rod portion 26 of the swinging rod 26C
2 f represents that is inserted between the curved rod portion 26c of the swing rod 26A _1, 26A ₂ as shown in FIG. 5 returns to the locked state as shown in FIG. 3, it was a buzzer 44 and the locked state The intermittent buzzer sound is emitted, and the same blinking is performed in the light emitting diode 43.

At this time, the curved rod portion 26f of the swinging rod 26C
When the end of the swing rod 26B stops rotating at that position when the tip of the swing rod 26A ₁ , 26
Since counterclockwise pivoting about A ₂ is not restricted, with the extension of the sliding member 32a of the push latch 32, swing rod 26A _1, 26A ₂ further anti shape than the rotational position of FIG. 3 The spoke 8 and the curved rod 26f of the swinging rod 26B are sandwiched by these curved rods 26c, whereby the movement of the spoke 8 is reliably prevented.

[0048] Conversely, when the tip of the curved rod portion 26c of the swing rod 26A ₁ or 26A ₂ comes into contact with the spokes 8, swing rod 26A _1, counter-clockwise rotation of 26A ₂ at the position Instead, the swinging rod 26B further rotates clockwise from the stop position in FIG. 3 with the extension of the sliding member 32a of the push latch 32, and the curved rod 26f moves to the swinging rod 26A. _1, is inserted between 26A ₂ of the curved rod portions 26c by the movement of the spoke 8 is reliably prevented.

As described above, the rear wheel locking device 20 having the above-described configuration can reliably lock the rear wheel 6 regardless of the position of the spoke 8 of the rear wheel 6 at the time of locking.
