Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device, and more particularly to an electronic lock device that does not use a mechanical cylinder lock which has been widely used in the past.

2. Description of the Related Art As shown in, for example, Japanese Patent Application Laid-Open No. 61-295154, a current automobile uses a steering lock that simultaneously controls a steering shaft and an ignition switch of the automobile. The steering lock is housed in a frame and rotated by a key between a locked position and an unlocked position, a cam rotated together with the key cylinder, a locked position engaged with the steering shaft, and disengaged. A locking rod moved by a cam and a spring to and from an unlocked position, and an ignition switch operatively connected behind the cam.

When you insert the key into the key cylinder and rotate it,
It can rotate sequentially to the "lock position", "off position", "ACC position", "on position" of the engine, and "start position" for operating the starter motor. If the key is removed in the "lock position", the rotation of the key cylinder becomes impossible and the operation of the ignition switch is prohibited, and the locking rod is engaged with the steering shaft, preventing the rotation of the steering shaft and preventing theft. .

Conventionally, when a key is inserted into a key cylinder,
A key detection device for detecting key insertion is provided in the steering lock device. The key detection device has a first pin slidably disposed in a key cylinder, a second pin for detecting the movement of the first pin, and a microswitch that is switched by the movement of the second pin. These components are installed inside or outside the steering lock device.

Japanese Utility Model Publication No. 61-28852 discloses a cylinder lock which can be unlocked without using a key. In this cylinder lock, an outer cylinder is inserted into a frame, and the frame and the outer cylinder are integrally fixed at a front end. An inner cylinder and a rotor are sequentially and concentrically inserted into the outer cylinder, and a cylinder lock mechanism is constituted by the inner cylinder and the rotor.

When the key is inserted into the rotor, the engagement between the inner cylinder and the rotor is released, and the rotor can rotate with respect to the inner cylinder. When the key is removed from the rotor, the inner cylinder and the rotor are engaged, and the rotor cannot rotate with respect to the inner cylinder. On the other hand, a solenoid plunger is provided on the side of the frame. The solenoid plunger is supported movably inward in the radial direction through holes provided in the frame, the outer cylinder, and the inner cylinder, respectively. The solenoid plunger is always held in a protruding state by the elastic force of the spring, but moves to the retracted position when the solenoid is energized. Therefore, the rotor can be rotated to the unlocking position without the key.

Further, Japanese Patent Application Laid-Open No. Sho 62-128857 discloses a Japanese Utility Model Publication No. Sho 61-2885.
No. 2 discloses a lock device for a vehicle that can operate a lock device at all times while the vehicle is running using the cylinder lock disclosed in No. 2.

Further, Japanese Unexamined Patent Publication No.
An electronic key device using the cylinder lock device disclosed in Japanese Patent Application Publication No. 1-28852 is disclosed.

Problems to be Solved by the Invention As described above, conventionally, a lock device is configured based on a cylinder lock. However, in recent years, with the development of electric and electronic technology, a lock device for a motorcycle that does not use a cylinder lock is required. At present, no such electronic lock device has been proposed.

An object of the present invention is to provide a novel handlebar lock device for a motorcycle that does not use a cylinder lock.

Means for Solving the Problems A handlebar locking device for a motorcycle according to the present invention includes a rotor device rotatably disposed in a frame between a locked position and an unlocked position, a frame attached to an end of the rotor device and a frame. A knob that protrudes outside the switch device, a switch means that is turned on when a rotor device is pressed to generate a timing pulse, and receives a radio signal including a specific code number when a timing pulse of the switch means generates a drive signal. A lock control circuit that is generated, and a lock member that is movably disposed in the frame to a lock position that prevents rotation of the rotor device or a release position that allows rotation, and is moved to a release position by a drive signal of the lock control circuit. And The rotor device includes an outer rotor member connected to the knob and rotatable and rotatable in the axial direction within the frame, and an inner rotor member that rotates integrally with the outer rotor member.

In another embodiment of the present invention, a request switch that is turned on when a rotor device is pressed and generates a timing pulse is provided. When a request switch timing pulse is generated, the lock control circuit receives a radio wave including a specific code number and generates a drive signal. Further, the cell switch generates a timing pulse when turned on, and when the timing pulse of the cell switch is generated, the cell control means receives a radio wave including a specific code number and generates a drive signal, and the drive signal of the cell control means is generated. Drives the cell motor.

Operation First, when the rotor device is pressed, the switch means is turned on, and a timing pulse is generated. The generation of this timing pulse triggers the lock control circuit, and when receiving a radio wave including a specific code number, the lock control circuit generates a drive signal. For this reason, since the locking member is moved to the release position, the rotor device can be rotated to the unlock position.

In another embodiment of the present invention, the request switch is turned on when the rotor device is pressed, a timing pulse is generated, the locking member is moved to the release position, and then the rotor device is rotated to the unlock position. . Thereafter, when the cell switch is turned on and a timing pulse is generated, the cell control means receives a radio wave including a specific code number, generates a drive signal, and drives the cell motor.

An embodiment of an electronic lock device according to the present invention applied to a handle lock device will be described below with reference to FIGS.

First, as shown in FIGS. 1 to 3, a handle lock device 10 according to the present invention includes a rotor device 12 rotatably arranged between a lock position and an unlock position in a frame 11, and a handle lock device 10 provided outside the frame 11. It has a knob 13 attached to the end of the protruding rotor device 12, and a locking member 15 for controlling the operation of the outer rotor member 21 by a locking control circuit.
FIG. 6 is a partial perspective view of a motorcycle embodying the present invention. As shown, the handle lock device 10 is provided adjacent to a handle 60 of a motorcycle. The handle 60 has a cell switch as a switch means for driving the cell motor.
61 are provided. As shown in FIGS. 2 and 4, the outer rotor member 21 has a first notch formed in a locked position.
17 and a second notch 18 formed at the off position.

The frame 11 has a housing 20, and the rotor device 12 is disposed in an opening 20a of the housing 20. Rotor device 12
Has an outer rotor member 21 connected to the knob 13 and movable and rotatable in the axial direction within the frame 11, and an inner rotor member 22 that rotates integrally with the outer rotor member 21. The outer rotor member 21 has a protruding portion 21a that protrudes inward and is inserted into a hole 22a having a non-circular cross section formed in the inner rotor member 22. The spring 23 wound around the protrusion 21a constantly urges the outer rotor member 21 outward.

The hanger 32 is combined with a locking rod 24 engageable with a steering shaft (not shown) of the motorcycle,
It moves together with the locking rod 24. Inner rotor member
The connecting portion 22b is provided on the 22 so as to protrude rearward. Connection part 2
2b is connected to an ignition switch (not shown).
The above-mentioned hanger 32, spring 33 and locking rod 24
Known components disclosed in Japanese Patent Publication No. 60-24055 can be used as they are. In the example shown in FIG.
A request switch 25 as switching means is disposed between the outer rotor member 21 and the inner rotor member 22, and the request switch 25 performs a switching operation when the outer rotor member 21 is pressed.

One end 15a of the locking member 15 is rotatably mounted on the frame 11 by a shaft portion 40 (FIG. 1), and the other end 15b is a solenoid 44.
Abuts on the plunger 45 of A tension spring 43 is attached to the hole 15c of the locking member 15, and the tension spring 43 urges the locking member 15 in a direction in which the protrusion 15d is always separated from the notch 17 of the outer rotor member 21. Also, the plunger 45 of the solenoid 44 as an actuator is a spring.
Due to the elastic force of 46, the projection 15d of the locking member 15 presses the locking member 15 in a direction in which the projection 15d engages the notch 17 of the outer rotor member 21. As described above, the locking member 15 is moved to the locking position where it engages with the outer rotor member 21 and the release position where it does not engage.

FIG. 5 is a circuit diagram showing an example of the lock control circuit 72. When the request switch 25 is turned on, a radio wave is emitted from the receiver 51, and the card entry device (card radio device) 50 that has received this radio wave generates a radio signal including a predetermined code signal. Radio waves emitted from the card entry device 50 are received by the receiver 51 and communication is performed. The receiver 51 is provided on the motorcycle adjacent to the handle lock device 10. The signal received by the receiver 51 is compared with the code signal stored in the storage circuit 53 by the comparison circuit 52, and when they match, the solenoid 44 is operated through the timer 54. Since the timer 54 generates an output for a certain time (1 to 3 seconds), the solenoid 44 is also energized for a certain time. Thereby, the locking member 15 moves from the locked position where the rotation of the outer rotor member 21 is prevented to the release position where the rotation is not blocked, and the knob 13 can be rotated.

In the above configuration, knob 13 is initially in the locked position. When the knob 13 is manually pressed, the request switch 25
Turns on. Here, communication of the card entry device 50 is started. If the code codes of the transmitter 50 and the receiver 51 match and the verification is OK, a drive signal is generated from the comparison circuit 52 and the output of the timer 54 activates the solenoid 44 for a certain period of time. Therefore, since the locking member 15 engaged with the notch 17 moves from the locking position to the release position, the knob 13 can be rotated toward the ON position.

When the knob 13 is rotated beyond the off position, the locking member 15 is in a state where it can be engaged with the second notch 18. However, the knob 13 is pressed to activate the request switch 25, and the wireless reception of the card entry device 50 is started again. If the code codes of the card entry device 50 and the receiver 51 match and the verification is OK, a drive signal is generated from the comparison circuit 52 and the output of the timer 54 activates the solenoid 44 for a certain period of time. Therefore, the locking member 15 that is to be engaged with the notch 18
Is held in the release position, so that the knob 13 can be turned toward the ON position to start the engine of the automobile.

At the time of getting off, the knob 13 is rotated from the on position to the off position. Contrary to the case described above, the locking member 15 is initially in a state in which it can be engaged with the second notch 18. But the knob
13 is pressed to activate the request switch 25, and the wireless reception of the card entry device 50 is started again. If the code codes of the card entry device 50 and the receiver 51 match and the verification is OK, a drive signal is generated from the comparison circuit 52 and the output of the timer 54 activates the solenoid 44 for a certain period of time.
Therefore, the locking member 15 that is going to engage with the notch 18 is held at the release position, and the knob 13 can be rotated toward the lock position. This is to confirm that the driver has a transmitter that generates a predetermined radio wave.

The present invention can be variously modified. For example, as shown in FIG. 7, the lock control circuit 72 can be constituted by a one-chip microcomputer. 7 and 10, the same parts as those shown in FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted. However, the solenoid 44 is the fifth
In the figure, the type operates only in one direction when energized.
The solenoid 44 shown in FIGS. 10 and 10 is of a type that operates bidirectionally by reversing the direction of current flow. In this embodiment, the second notch 18 is omitted.

A receiver 51, an ignition switch 71, a request switch 25, and a cell switch (cell / request switch) 61 are connected to different input terminals of the lock control circuit 72. Also, a ROM 73 for storing a program for operating the lock control circuit 72 is connected. The solenoid 44 is connected to two output terminals of the lock control circuit 72 via drive circuits 74 and 75. A self-motor relay 78 and a light emitting diode 79 are connected to other different output terminals of the lock control circuit 72 via drive circuits 76 and 77, respectively.

The lock control circuit 72 shown in FIG. 7 is operated, for example, by the operation sequence shown in the flowchart of FIG.

In step 101 from the start of step 100, the driver presses the knob 13 to turn on the request switch 25. Then, the radio wave from the transmitter 50 is received (step 10).
2), the lock control circuit 72 determines whether or not this radio wave contains a predetermined code signal (step 103). If the predetermined code signal is not included, the process returns to the start.If the predetermined code signal is included, the process proceeds to step 104, where the lock control circuit 72 sends an output from the output terminal to the drive circuit 74, and the solenoid 44
Is operated for a fixed time (step 105). Thereafter, in step 106, the lock control circuit 72 determines whether or not the ignition switch 71 has been turned on and has received an input signal.
It is determined whether or not the knob 13 has been rotated from the lock position to the ON position. If knob 13 is not turned to the on position,
Proceeding to 122, it is determined whether a predetermined time has elapsed. Before time elapses, the process returns to step 106, and after time elapses, step 1
In 23, a current flows in the reverse direction from the lock control circuit 72 to the solenoid 44 through the drive circuit 75, and the solenoid 44 is moved to the locking position, and then returns to the start.

In step 106, when the knob 13 is turned to the ON position, the process proceeds to step 107, where the cell switch 61 is turned on. Here, the lock control circuit 72 receives the radio wave from the transmitter 50 (Step 108), and determines whether or not a predetermined code signal is included (Step 109). If the predetermined code signal is not included, the process returns to step 107. When a predetermined code signal is included, the lock control circuit 72 sends an output to the drive circuit 76 to drive the starter motor relay 78 (step 110) and starts the engine (step 111). Then, step 1
Proceeding to 12, it is determined whether the cell switch 61 has been turned on.
This is determined when the energization of the starter relay 78 does not start the engine or when the engine stalls. When the cell switch 61 is not operated, a running state of the motorcycle or a non-starting state of the engine is obtained.

Next, when the driver stops the engine of the motorcycle, the lock control circuit 72 determines whether or not the knob 13 is in the ON position in step 113 based on the output of the ignition switch 71. If it is in the ON position, the process returns to step 112. When it is in the off position or the locked position, the engine is stopped (step 114). Further, the lock control circuit 72 determines whether or not the knob 13 is at the lock position (step 115). Step 116
And 124 actuate the drive circuits 77 and 81, respectively, to activate the light emitting diodes as indicators of the lock position and the off position.
Light 79 and 80. Thereafter, in step 117, it is determined whether or not the request switch 25 has been turned on. If not turned on, return to step 113; if turned on, step 1
At 18, the receiver 51 receives the radio wave. It is determined whether or not a predetermined code signal is included in the radio wave received from the receiver 51 (step 119). When the code signal is not included or the radio wave is not received, the process returns to step 117. When the predetermined code signal is included, the solenoid 44 is operated in the reverse direction from the lock control circuit 72 through the drive circuit 75 (step 120) to move the locking member 15 to the locking position. Alternatively, 80 is turned off (step 121).

In another embodiment shown in FIG.
May be omitted, and the handle lock device may be constituted only by the cell switch 61. That is, in step 130 from the start of step 129, the driver presses on cell switch 61. Therefore, the radio wave from the transmitter 50 is received (step 131), and the lock control circuit 72 determines whether or not this radio wave contains a predetermined code signal (step 131).
132). If the predetermined code signal is not included, the process returns to the start. If the predetermined code signal is included, the process proceeds to step 133. Here, it is determined whether or not the knob 13 has been turned to the ON position. If rotated to the on position, the process proceeds to step 134, and if not, the process proceeds to step 149. Step 150-152
Is the same as steps 104 to 106 in FIG.
Steps 3 and 154 are the same as steps 122 and 123 in FIG.
The lock control circuit 72 sends an output from the output terminal to the drive circuit 74 to operate the solenoid 44 for a certain time (step 15).
1). Thereafter, in step 152, the lock control circuit 72
Determines whether the knob 13 has been turned from the locked position to the on position, based on whether the ignition switch 71 has been turned on and an input signal has been received. If the knob 13 has not been turned to the ON position, the process proceeds to step 153, where it is determined whether or not the position time has elapsed. Before the lapse of time, the process returns to step 152, and after the lapse of time, in step 154, a current flows in the opposite direction from the lock control circuit 72 to the solenoid 44 through the drive circuit 75, and the solenoid 44 is moved to the locking position. Return to

In step 152, when the knob 13 is rotated to the ON position, the process proceeds to step 134 via step 133, and the cell switch 61 is turned on. Steps 134 to 143 are the same as steps 107 to 116 in FIG. Thereafter, in step 144, it is determined whether or not the cell switch 61 has been turned on. If not turned on, return to step 140; if turned on, step 1
At 45, the receiver 51 receives the radio wave. Step 145-1
48 is the same as steps 118 to 121 in FIG.

As shown in FIG. 10, the handlebar lock device for a motorcycle according to the present invention may be constituted by a discrete circuit. When the ignition switch 71 is off, the request switch 25 is turned on. For this reason,
The output of the one-shot multivibrator 55 causes the AND gate 56 to generate an output, the RS flip-flop 57 is set, and a signal is applied to the AND gate 58. The AND gate 56 applies a trigger signal to the receiver 51 via the OR gate 154 to make the receiver 51 receivable. Therefore, the signal received by the receiver 51 is compared with the code signal in the storage circuit 53 in the comparison circuit 52, and when they match, the comparison circuit 52
Produces an output. Therefore, the AND gate 58 generates an output, operates the one-shot multivibrator 155, sets the RS flip-flop 156, and urges the solenoid 44 in one direction by the output of the timer 157. at the same time,
The timer 158 is operated by the output of the RS flip-flop 156. Timer 158 has a time interval of about 500 milliseconds. Therefore, the locking member 15 is moved to the release position. The one-shot multivibrator 159 generates an output when the timer 158 falls, and outputs the RS flip-flop 1 through the OR gate 170.
Reset 56.

Thereafter, when the knob 13 is turned from the off position to the on position, the ignition switch 71 is turned on. Therefore,
The AND gate 56 is turned off, and the AND gate 160 is turned on. Therefore, when the cell switch 61 is turned on, the one-shot multivibrator 161 generates a pulse having a sufficiently long time width. For this reason, since the AND gate 160 generates an output, the receiver 51 receives the electric wave again. Also,
The RS flip-flop 57 is reset via the OR gate 171. Here, when the comparison circuit 52 detects the same code signal as the signal stored in the storage circuit 53, an output is generated. The output of the comparison circuit 52 turns on the AND gate 162, which activates the one-shot multivibrator 164 and switches the RS flip-flop 165 to the set state. Therefore, an output is provided from the RS flip-flop 165 to the AND gate 166. One-shot multivibrator 16
Since 1 has a sufficiently long pulse width, AND gate 166 generates an output, energizing drive circuit 167 and activating self-motor relay 78. AND gate 162 to drive circuit 1
67 constitutes the cell control means 59.

Then, when the ignition switch 71 is turned off and the request switch 25 is turned on, the output of the one-shot multivibrator 55 again causes the AND gate 56 to generate an output, and the AND gate 56 sends a trigger signal to the receiver 51 via the OR gate 154. Give it and make it receivable. Therefore, the signal received by the receiver 51 is compared with the code signal in the storage circuit 53 in the comparison circuit 52, and when they match, the comparison circuit 52 generates an output. Therefore, the AND gate 163 generates an output, and the RS flip-flop 156 and the
In addition to resetting 165, the RS flip-flop 57 is reset via the OR gate 171. Further, an output of about 500 milliseconds is generated in the one-shot multivibrator 168, and the solenoid 44 is operated in the reverse direction. Therefore, the locking member 15 moves from the release position to the locking position.

In the embodiment of FIG. 10, the request switch 25 and the one-shot multivibrator 55 are omitted, and the output terminal of the one-shot multivibrator 161 is connected to an AND gate 56.
And 160 may be connected.

The request switch 25 can be provided without being provided in the handle lock device 10 or independently of the cell switch.

The above embodiment of the present invention can be variously modified. For example, instead of a rotatable locking member, an eleventh
As shown in the figure, a locking member constituting a plunger of the solenoid 44 can be used. In addition, as shown in FIG. 7, the request switch 25 can be operated by a notch of the rotor device.

Effect of the Invention As described above, according to the present invention, it is possible to obtain a handlebar lock device for a motorcycle that is easy to operate using radio waves without using a key.
