Description

Description: TECHNICAL FIELD The present invention relates to a steering lock device capable of locking and unlocking by a manual operation of a knob without using a key or a key, and in particular, unlocking by a key. In this case, the present invention relates to a steering lock device having a structure in which a case cannot be rotated by a knob and a key cannot be inserted into a cylinder when unlocked by the knob.

[Conventional technology and problems]

When driving a vehicle, conventionally, a key that matches the steering lock has been used to lock the steering shaft that actuates the steering lock.

However, in recent years, doors and trunks of automobiles can be locked without using keys, such as buttons, radio locks, infrared locks, etc., but when locking and unlocking the steering shaft and starting and stopping the engine must be done with keys. Is inconvenient because you must always carry your key with you.

Therefore, the applicant has provided a steering lock having an actuator that operates a check lever so that it can be operated without a key (Japanese Patent Application No. 61-074341).
~ 3).

The present invention is a further improvement based on the invention of the above-mentioned patent application. Normally, either the key or the steering lock that operates without the key operates either one, but both of them are erroneous or mischievous. If this is done, the cylinder and the case may move separately, which may cause problems when the steering shaft is locked, so this is reliably prevented.

[Means for solving problems]

In order to achieve the above object, in the present invention, a frame of a steering lock and a cylinder case having a knob for manual operation formed on a front surface are loosely fitted in a position cap integrally connected to the frame, A rotor, which is pivotally operated by a key, is loosely fitted in the cylinder case, and one side has a key sensing portion that is spring-biased so as to penetrate the cylinder case and enter the rotor at the side. A check lever having a locking portion that holds a locking rod at the time of unlocking is pivotally attached to the frame at the other end, and a plunger that is driven by an actuator and engages with the check lever is provided in the movement allowance space of the plunger. The key sensing portion of the check lever that penetrates through the lock lever engages with the hole of the cylinder case when locked and prevents the cylinder case from rotating. In the steering lock device, a slider that has a leg portion that can be inserted into and removed from a hole provided in the position cap, is inserted into holes formed in the rotor and the cylinder case, and is spring-biased toward the center of the rotor. The lock case and the slider are provided with a slider that is pressed against the lock case.

The hole 2b formed in a portion thicker than the formed portion and the rotor 4 hole 4b are movable in and out of the rotor 4 and the other locking portion 13b is provided with the locking rod 8.
The system can be detached from the engaging portion 8a.

The check lever 13 uses the coil spring 14 to detect the key sensor 13
The a is constantly urged in the direction of entering the rotor 4.

 The coil spring 14 is fixed by a cover 14 '.

The check lever 13 is a movable space 11 for the plunger 11.
It is arranged so as to extend through a and contact the drive step 11b.

If the hole 2b of the cylinder case 2 formed as described above is made thick, it is possible to provide strength.

A sub-actuator 15 is provided on the front surface of the main actuator 10, and a spring 16 is
A sub-plunger 17 which is sucked against the main plunger 11 is arranged in a direction intersecting with the main plunger 11.

The main plunger 11 is provided with a flange-shaped stopper 18, the sub-plunger 17 is provided with a stopper plate 19 which is coupled to the stopper 18, and the stopper plate 19 has a passage for the stopper 18 of the main plunger 11. A cut-off portion 19a is formed to allow

Further, as shown in FIGS. 7 and 8, holes 4c and 2c are formed in the rotor 4 and the cylinder case 2, and the depths of the holes 4c have the same length and the outer peripheral surface of the rotor 4 is formed. While inserting the slider 20 having a back surface of the same shape as the inside of the hole 4c,
A slider lock case (22) which is inserted into the hole (2c) and presses the slider (20) with a spring (21) is provided with a leg (22a) which can be detached from the hole (1c) formed in the position cap (1a).

Reference numeral 23 is a spring bearing 2d provided on the outer peripheral surface of the cylinder case 2.
A steel ball urged outward by a spring 24 inserted into the cylinder 1 and rotating together with the cylinder case 2 while maintaining contact with the inner peripheral surface of the frame 1. As shown in FIG. When it comes into contact with the hole 1d formed in the hole 1, it protrudes into the hole 1d and strikes a chain position detecting switch.

In the present embodiment configured as described above, in order to unlock the handle lock without a key, a keyboard button (not shown) is pressed according to the unlocking number, and when the stored number matches, a match signal is issued from the controller. By operating the ab actuator 15, the sub-plunger 17 is attracted against the spring 16, whereby the stopper plate 19 retracts from the movement trajectory of the stopper 18 and the stopper 18 passes through the cutout portion 19a. Such a state is maintained for a certain period of time.

During this time, the controller 21 keeps the main actuator 10
A signal that energizes the device is output for a fixed time. When the main actuator 10 is energized, the main plunger 11 moves backward while driving the check lever 13 in the unlocking direction, and is held by the magnet built in the main actuator 10. Then, when the signal output from the controller 21 for energizing the sub-actuator 15 is cut off after a certain period of time, the sub-plunger 17 is returned to the original position by the spring 16 and the stopper plate 19 is also returned to the original position. It returns and holds the unlocked position of the main plunger 11.

Drive step 11 when the main plunger 11 is retracted
b drives the check lever 13 against the coil spring 14 to move it from the X position in FIG. 6 to the Y position, whereby the key sensing portion 13a is disengaged from the cylinder case 2 and the locking portion 13b is locked by the locking rod. 8 is brought into pressure contact with and brought into an engageable state.

In this state, when the knob 3 is grasped by hand without using the key and the cylinder case 2 is rotated, the slider lock case 22 and the spring 21 are urged toward the rotor 4 side.
Since the leg 22a is disengaged from the hole 1c and the engagement between the slider lock case 22 and the position cap 1a is released, as shown in FIG.
Rotate as a unit, and the ignition switch 6
Is switched from the Acc position to the ON to START position, and the cam 7a fixed to the rotor 4 moves the locking rod 8.

At this time, the check lever 13 is attached to the engaging portion 8a of the locking rod 8.
Locking portion 13b of is engaged. Therefore, the unlocked position of the locking rod 8 is maintained until a lock signal is sent from the controller 21 to the actuator 10 while the vehicle is stopped.

If the key is accidentally inserted into the rotor 4 in such a state, the leg 22a comes into contact with the position cap 1a and the slider 20 cannot be retracted, so that the key cannot be inserted (see FIG. 8C).

Therefore, it is prevented to insert the key and rotate only the rotor in the unlocked state without the key.

Further, when unlocking using the key, when the key is inserted into the rotor 4, the slider 20 and the slider lock case 22 retreat against the spring 21 as shown in FIG. Is inserted into the anti-1c, the rotor 4 is restrained by the position cap 1a, and the rotor 4 is rotated by the rotation of the key.
Only rotate.

In addition, the key detection unit 13 that comes in contact with and separates from the key by inserting the key
Since a is retracted and the check lever 13 is rotated in the direction of the locking rod 8, if the key is rotated in the START position direction in this state, the engaging portion 13b of the check lever 13 will cause the locking rod 8 to turn off. The locking rod (8) is engaged with the locking part (not shown) to hold the locking rod 8 in the locking position.

In such a state, even if the unlocking number is pressed using the keyboard, the leg 22a of the slider lock case 22 to be inserted into the hole 2c of the cylinder case 2 is fitted into the position cap, and therefore the cylinder case 2 is not locked even if the knob is used. Does not rotate (see FIG. 8B).

That is, when the key is unlocked without the key, the key cannot be used for locking and unlocking, and when the key is unlocked, the key cannot be unlocked without the key.

[Effect]

It is prevented that the rotor is rotated with the key after unlocking without the key due to mistakes or mischief, or the cylinder case and rotor are prevented from rotating by grasping the knob after unlocking with the key. The steering function can be ensured by solving the problems that the positions cannot be matched and the case cannot be locked, and the problems that the tumbler grooves of the cylinder case and the case are not aligned and the key cannot be removed.
