Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a bicycle locking device that can be unlocked electrically.

[0002]

2. Description of the Related Art As a locking device for an electric unlocking type bicycle, a device capable of unlocking by a remote control is known. This electric locking device is equipped with a battery as a driving power supply, and compares the received identification code with the identification code stored in the device in advance so that only the unlock command from the owner of the bicycle is accepted. The lock mechanism can be unlocked to improve theft prevention.

However, in the bicycle locking device, when the locking rod in the locked state is unlocked, the locking rod is returned to the unlocked position by a strong force due to the spring force. Due to the shock at the time of unlocking, the connection between the power supply battery and the battery terminal may be momentarily separated and the power supply may be temporarily cut off. In particular, when the power supply is cut off during the unlocking operation, the unlocking operation remains stopped even if the power supply is restored thereafter, and it becomes impossible to lock. Since this situation occurs inside the device, the user cannot recognize it until the next time to lock, and in order to enable the locking mechanism to be locked, the unlock command is sent again to complete the unlocking operation. Since it had to be done, the operability had deteriorated. Even when the battery level is low, the unlocking operation may not be completed and locking may not be possible, as described above.

If they match, a drive signal is output to the motor drive circuit 158 based on the unlock command, and LED1
64 and the buzzer 166 are operated. That is, it has the function of accepting the unlock command and outputting the drive signal only when the transmitted personal identification number and the registered personal identification number are compared and coincident with each other. Since the ID code of this EPROM is written at the time of shipment from the factory and has a length of 16 bits or more, it is possible to combine 2 ¹⁶ (about 65,000 ways) or more, and the antitheft performance in practice is extremely high. It's getting higher.

When the CPU 156 determines that the ID codes match, the motor drive circuit 158 receives the drive signal output from the CPU 156, drives the drive motor 74, and causes the eccentric cam 71 to operate. It is a circuit for moving the lock lever 40 to the unlocked position. The limit switch 52 connects the rotary drive shaft 77 to the eccentric cam 71.

In the switch, the switch projection 52a is engaged with the recess 51b to turn off (see FIG. 7). CPU15
6 drives the drive motor 74 to move the eccentric cam 71 until the limit switch 52 is turned off, and when the limit switch 52 is turned off, the eccentric cam 71 can be locked.
Then , the drive of the drive motor 4 is stopped.

The LED 164 lights up (or blinks) for a predetermined time in response to a lighting command from the CPU 156, and functions as a notification light transmission means for notifying the user that the motor drive circuit 158 is operating. The buzzer 166 functions as a notification sound unit that sounds a predetermined time according to a command from the CPU 156 and notifies the user that the motor drive circuit 158 is operating.

The battery 160A is formed by connecting two dry batteries in series, and functions as a power source for supplying electric power to the receiving unit 210. The battery 160A is housed in the battery case 160C shown in FIG. Further, the voltage regulator 160B is necessary when the bicycle locking device of the present invention is mounted on an electrically assisted bicycle, and lowers the battery voltage of 24V to 3V and supplies power to the receiving unit 210. is there. The reception circuit power supply control circuit 162 includes a battery 160A.
Alternatively, the voltage regulator 160B and the CPU 156
Is a circuit for controlling power supply to the RF AMP 150 and the detection circuit 154 in response to a power ON / OFF command from the CPU 156.

Next, the remote control unlocking operation of the electric unlocking type bicycle locking device having the above structure will be described with reference to FIGS. 7 to 13. Now, consider a locked state (FIG. 4) in which the lock rod 30 is rotated to the wheel lock position by the operation knob 32, and the lock rising surface 42 of the lock lever 40 is engaged with the lock end surface 38 thereof. At this time, the key cylinder 64 of the key cylinder type manual unlocking device 60 is in the neutral position (lock position).
It is in.

In this normal locked state, the remote control transmitter 8
When the unlock switch 82 of 0 is pressed, as shown in FIG. 10, the interrupt of the unlock switch 82 enters the CPU 134 of the remote control transmission device 80 (S10), and the CPU 134 cancels the stop mode and starts (S11). . CPU1
34, in order to improve the reliability of detection, the transmission ID code stored in the EPROM is read out twice consecutively (S12, S13), and if the first and second ID codes match. (S14), the power source of the RF OSC 136 is turned on (S15). And CPU134 is ID
The code and the unlock command are transmitted (S16), the transmission time t4 is set (S17), and the processes of S15 to S18 are repeated until the transmission time t4 elapses (S18). When the transmission time t4 has elapsed, the power supply of the RF OSC 136 is turned off (S19), and the stop mode is entered (S20).

On the other hand, the electric unlocking mechanism is the battery 160A.
The following processing is executed in the state where the
~ Fig. 13). First, the CPU 156 checks whether or not the eccentric cam 71 is in the lockable position by turning on / off the limit switch 52 each time the power is turned on (S21). Since the eccentric cam 71 is not in the lockable position while the limit switch 52 is on, the drive motor 74 is turned on to move the eccentric cam 71, and the LED 1
64 is turned on for t3 hours and the buzzer 166 is turned on for t3.
The user is informed that the drive motor 74 is in operation by sounding for a time (S22, S23). Then, when it is detected that the limit switch 52 is off, the drive motor 74 is turned off (S24), and the eccentric cam 71 is stopped at the lockable position.

In this operation, after the battery 160A and its contact point are momentarily separated due to vibration or shock,
The same is done after the contact is restored. Therefore, the eccentric cam 71 is always in the lockable position (the lock lever 40
It will stop at a position that allows movement from the unlocked position to the locked position) . Next, the CPU 156 reads the ID code for collation stored in the EPROM twice in succession (S25, S26) in order to improve the reliability of detection, and the first and second ID codes match. If (S27),
The reception interval timer t1 is set (S28).
Then, the CPU 156 shifts to the HALT mode (S2
9) Stand by in the ID code reception waiting state.

When the reception interval timer t1 times out (S30), the CPU 156 releases the HALT mode and starts up (S31), and sets the reception time t2 (S32). The reception time t2 is a time for receiving the ID code and the unlock command transmitted from the remote control transmission device 80, and the CPU 156 supplies power to the reception circuit via the reception circuit power supply control circuit 162 until the reception time t2 elapses. Supply.

When the ID code and the unlock command are transmitted from the remote control transmitter 80 within the reception time t2, the CP
U156 is a receiving circuit (RF AMP150, antenna 1
52, the ID code is received via the detection circuit 154) (S33), this is collated with the collation ID code, and both I
If the D codes match (S34), the unlock command is received (S35). Then, the LED 164 is turned on for t3 time and the buzzer 166 is run for t3 time to notify the user that the unlocking operation is being performed (S36), and the drive motor 74 is driven (S37). By this drive, the worm gear 74a, the worm wheel 76a, the reduction gear train 7
6, the rotary drive shaft 77 is rotationally driven, the eccentric cam 71 fixed to the rotary drive shaft 77 outside the case 72 is rotated, and the electric lock release standing portion 43 is pushed to move the lock lever 40 to the clock in FIG. Rotate in the direction.
Then, as a result of disengagement between the lock upright portion 42 and the lock end surface 38, the lock rod 30 is instantaneously rotated by the force of the tension spring 34, and the tip lock portion 37 is moved to the wheel insertion recess 11.
To retract and unlock. The position of the lock lever 40 in FIG. 5 is the unlocked position, and in this state, even if the lock rod 30 is moved from the unlocked position to the locked position, it is not locked.

When the limit switch 52 is turned off, the CPU 156 detects that the eccentric cam 71 has moved around to the lockable position after making one round (S38), and stops the operation of the drive motor 74 (S39). After the above operation is completed, the CPU 156 sets the reception interval timer t1 to set HA
The mode shifts to the LT mode (S40, S41), and the ID code reception standby state is set. When the eccentric cam 71 is rotated to the lockable position, the lock lever 40 is also in the lockable position in FIG. When the ID code is not received within the reception time t2, the received ID code does not match the stored ID code, or the unlock command is not received, the CPU 156 receives the reception time t2. After elapse (S
42), the reception interval timer t1 is set, and the mode shifts to the HALT mode again (S43, S44).

As described above, the unlocking operation of the electric unlocking mechanism is completed. In this unlocked state, that is, when the lock lever 40 is in the lockable position, the lock can be locked by holding the operation knob 32 and fully rotating the lock rod 30 in the lock direction. At the moment when the lock end surface 38 exceeds the lock upright portion 42, the lock upright portion 42 is moved by the force of the tension spring 46.
Moves to an engagement position with the lock end surface 38, and becomes the initial normal lock state.

Next, in the manual unlocking operation, the key 63 is inserted into the key cylinder 64 of the key cylinder type manual unlocking device 60,
The key cylinder 64 is rotated clockwise in FIG. Then, the rotating arm 61 that rotates integrally with the key cylinder 64 pushes the manual unlocking standing portion 44 to rotate the lock lever 40 in the clockwise direction in FIG. 4, so that the lock standing portion is unlocked in the same manner as the remote control unlocking operation. 42 and lock rod 30
Is disengaged from the lock end surface 38 and the lock is released.

As is apparent from the above description, in the present embodiment, the battery 160A is released before the unlocking operation of the electric unlocking mechanism is completed due to the impact generated by the force of the tension spring 46 at the unlocking time or the insufficient battery level. Even when the power supply from the power supply is cut off, when the power supply is restored, the eccentric cam 71
Is returned to the lockable position (S21, S22),
It is possible to prevent a situation in which the lock cannot be performed, and the user does not need to operate the remote control transmission device 80 again, so that the operability is improved. In addition, power consumption of the remote control transmission device 80 can be reduced in accordance with the improvement in operability.

Further, in the present embodiment, the recess 51b is formed in a part of the circular cam surface 51a of the cam member 51, and the switch projection 52a of the limit switch 52 is engaged with the recess 51b, that is, the switch projection 52a. Since the lockable position of the eccentric cam 71 (lock lever 40) is detected in a non-pressed state in which the eccentric cam 71 is projected by the spring force, the eccentric cam 71
Compared with the case where the lockable position of the switch projection 52a is detected by the pressed state of the switch projection 52a, the possibility of damage to the switch projection 52a due to the impact received while the bicycle is running can be reduced, and the durability of the limit switch 52 can be improved. it can. Well
According to the present embodiment, the limit switch 52 does not turn off at any position other than the lockable position of the eccentric cam 71, and the lockable position of the eccentric cam 71 can be accurately detected.
The detection position can be set easily. Furthermore, in this embodiment,
The LED 164 and the buzzer 166 inform the user that the drive motor 74 is operating, so that the user can recognize that the unlocking operation is being performed. In addition, even when the ID code received by the receiving circuit from the remote control transmitting device matches the predetermined ID code, the LE
Since the D164 and the buzzer 166 operate, the location of the bicycle can be easily known.
