Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a steering lock device for preventing theft by disabling the rotation of the steering wheel when parking a vehicle such as a motorcycle. This relates to a steering lock device that is linked to a starter device.

[Prior art] Motorcycles are usually equipped with a steering lock device to prevent theft when parked, and this steering lock device is activated when the power (ignition switch) is turned on.
- It is operated by a key for performing OFF switching. This steering lock device generally incorporates a lock mechanism with a lock pin that comes out and retracts when the key is operated, and the steering lock is built into the ignition switch to limit the rotation of the steering wheel. A locking device having only a mechanism is known.

For example, Fig. 1 shows the steering lock device. In the figure, reference numeral 1 denotes a head pipe at the front end of the vehicle body frame 2. A steering shaft 3 is rotatably fitted and supported in the head pipe 1, and a handlebar (not shown) is attached to the upper end of the steering shaft 3. ) is fitted and fixed to an upper bracket 4 that fixes the upper bracket. An arcuate member 5 is welded to the outer peripheral surface of the upper end of the head pipe 1, and holes 6°6 are bored approximately radially (direction toward the center of the head pipe 1) on both left and right sides of the arcuate member 5. Reference numeral 7 denotes an ignition/lock member, and this lock member 7 is fixed to the front end of the central portion of the upper bracket 4, and the lock pin 9 is locked by operating the key 8.
It is designed so that it appears and disappears toward the head pipe 1 side.

Therefore, lock pin 9 can be moved to head pipe 1 by key operation.
By protruding in the opposite direction and fitting into either the left or right hole 6 provided in the arc-shaped member 5, rotation of the handle can be prevented.

Also, although not shown, there is a structure in which the ignition switch and steering lock cannot be operated in one action, in other words, the steering lock will not be released even if the ignition switch is turned on from the leaf F (each is separate, the lock is near the head pipe, and the ignition switch (e.g., if it is installed in a different location).

As a prior art, for example, JP-A-59-186789 is mentioned.

[Problems to be Solved by the Invention] However, in the case of the above structure, it is necessary to release the steering lock and roughly turn on the ignition switch to start the vehicle, which is cumbersome to operate.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and at the same time, the lock pin of the lock member is moved in and out by an electromagnet activated by the operation of an ignition switch, and at the same time, a circle welded to the lock pin and the head pipe is It is an object of the present invention to provide a steering lock device that allows connection to a starter relay only when the arc-shaped member is disengaged from the hole.

[Means for Solving the Problems] (1) A handle member is rotatably supported by a head pipe at the front end of the vehicle body frame via a steering shaft.

(2) Key operation (ignition switch ON).

A locking member that is activated by other instructions such as OFF, LOC, PARK, etc.) or other instructions such as a card type or a secret code using a button is fixed to the handle member or the head pipe and the vicinity of the head pipe.

(3) A steering lock device for a two-wheeled vehicle that prevents rotation of a handle member by locking a lock member (operating an ignition switch to the LOCK position).

(4) A steering lock relay is installed between the battery and the starter relay, and the ignition switch is turned on and off with the lock member unlocked.

Connection to the starter relay is possible only when it is in PARK etc. (other than LOCK).

(5) The lock pin is moved in and out by the magnetic force of the electromagnet activated by operating the ignition switch (LOCK+other). Ignition switch is LOC
When in position, the locking pin protrudes to lock rotation of the handle member. When the lock pin is not in the LOC position, the lock pin is retracted from the hole and at the same time activates the steering lock relay and is connected to the starter relay to prepare for starting the engine.

[Function] When the ignition switch is in the LOCK position, the lock pin protrudes and the rotation of the handle member is locked, and the steering lock relay is not activated, so the connection to the starter relay is cut off. Therefore, the engine will not start even if the starter switch is turned on.

When the ignition switch is connected to a position other than the OC position, the handle member is unlocked by actuation of the electromagnet. At the same time, the steering lock relay is activated and connected to the starter relay, and by turning the ignition switch to the ON position and turning the starter switch to ON, the engine can be started.

In this way, when the ignition switch is operated, the lock pin is moved in and out using an electromagnet to lock and unlock the handle member, and the engine can only be started when the handle member is unlocked and the ignition switch is turned on. It made it possible.

[Example] A steering lock device according to the present invention will be explained with reference to the drawings.

FIG. 1 is a wiring diagram showing only the gist of one embodiment. In the figure, reference numeral 10 denotes a battery, and the battery 10 operates a starter motor (not shown) and lights up various lighting devices such as a headlight, a taillight, and a direction indicator. 11 is fuse,
12 is an ignition switch, and the ignition switch 12 has a Kano F terminal 12a, an ON terminal 12b and an [OCK@child 12c, and a Kano E@child 12a.
If it is connected to , power will not be applied to the various electrical devices that follow. When connected to the ON terminal 12b, it is in a state where various electrical devices can be operated. LOCK terminal 1
2C, the lock pin of the lock member protrudes by the operation of an electromagnet, which will be described later, to lock the rotation of the handle member, and in this state, the operating key can be attached and detached. A kill switch 13 is used to stop the engine (not shown) in case of emergency. 14 is a starter switch for operating the starter motor. 15 is a steering lock relay, 16 is a starter relay, and 11 is an indicator, when the steering wheel member is free and the ignition switch is turned on.
When the steering lock relay 15 is in the N position, it is connected to the starter relay 16 by the operation of the steering lock relay 15, and when the starter switch 14 is turned on, the current from the battery 10 is passed to the starter relay 16, which activates a starter motor (not shown) to start the engine. . When the steering wheel member is locked, the steering lock relay 15 is activated.
Starter relay 16 to be connected to indicator 11
Power is not applied to the engine, the engine does not start, and a warning sound is emitted or a warning light is turned on.

18 is a locking member installed near the handle, and 19 is a locking pin that protrudes and retracts from this locking member 18. 2
0 is an electromagnet, and 21 is a drive cam for moving the lock pin 19 in and out. The cam 21 is made of a non-magnetic material, and a magnetic material 22 is embedded in a position corresponding to the electromagnet 20. As shown by the arrow in the figure, the drive cam 21 is lowered by the operation of the electromagnet 20, and the groove 19a cut in the lock pin 19 is
Slide the lock pin 19 inside to project it to the left. Further, when the drive cam 21 is raised by the operation of the electromagnet 20, the lock pin 19 is moved and retracted to the right by the action of the spring 23.

The upper electromagnet 20a in the figure is connected to the LOCK terminal 12C of the ignition switch 12, and the lower electromagnet 20b is connected to the LOCK terminal 12C of the ignition switch 12.
are connected to terminal 12c, respectively, and LOCK terminal 1
2c, the lock pin 19 is caused to protrude by the operation of the drive cam 21, as described above.

On the other hand, a steering lock switch 24 is formed on the rear end 19b of the lock pin 19, and is connected to the ON@ terminal 12b of the ignition switch 12, and is energized when the lock pin 19 is in the retracted state. The steering lock relay 15 is connected to the steering lock relay 15. As a result, when the lock pin 19 is retracted, that is, when the handle member is in a free state, the steering lock relay 15 is activated and the ignition switch 12 is turned on, thereby energizing the starter relay 16 from the battery 10. It is what it is.

Therefore, when the handle member is in a locked state, the starter relay 16 is electrically prevented from operating.

Although the ignition switch 12 has been described as being operated using a key, it goes without saying that other instructions such as a card format or a secret number using a button or the like may also be applied.

[Effects of the Invention] As described above, according to the steering lock device according to the present invention, the steering wheel member is locked and released by the operation of the electromagnet, so it is not possible to start the engine or start the vehicle while the steering wheel member is in the locked state. There was no need to do anything anymore.
