Description

  The present invention relates to a steering lock device that locks a key cylinder with a key lock mechanism so that the key cannot be removed.

  The steering lock device of an AT car has a key lock mechanism with a key when the shift lever is set to a reverse range “R” other than the parking range “P”, a neutral range “N”, or a drive range “D”. Some have a key interlock device that locks the cylinder so that the key cannot be removed.

  The key interlock device generally uses a solenoid. For example, when the shift lever is in a position other than “P”, the solenoid is energized to cause the plunger to protrude and engage the cam of the steering lock device. The key cannot be rotated to the “LOCK” position. Further, when the energization is released, it returns to the original immersion position by the spring force (see Patent Document 1).

Some solenoid plungers are fitted with the cam portion at the rear of the key cylinder, but some have a link mechanism that converts the linear motion of the plunger into rotational motion in order to transmit the driving force more efficiently. .
The rotating shaft of the link mechanism is fixed by caulking or press-fitting to a component such as a steering lock body, but a dedicated facility is required and an extra man-hour is required.

These two spring receiving portions 50 b hold the first spring 61 so as to be inserted into the first spring 61, respectively.

  The spring receiving portion 50c protrudes upward in FIG. 6 from the lower portion in FIG. 6 in the hollow portion 50a and is formed in a substantially cylindrical shape. The spring receiving portion 50 c holds the second spring 62 so as to be inserted into the second spring 62.

  The inclined surface 50 d is provided at a portion where the slider 50 comes into contact with the cam portion 21 of the camshaft 20. The inclined surface 50d can move the slider 50 in a direction away from the camshaft 20 (upward in FIG. 6) by receiving force from the cam portion 21 when the camshaft 20 rotates from the ACC position to the LOCK position. Inclined in the direction.

  Two first springs 61 are provided, each having one end attached to the spring receiving portion 50 b of the slider 50 and the other end being a coil spring attached to the cover portion 30 b of the solenoid 30 integrated with the solenoid 30. . The first spring 61 urges the slider 50 in the direction in which the link 40 becomes the restriction position, that is, the direction in which the blocking portion 43 approaches the camshaft 20 (downward in FIG. 6).

  The second spring 62 is a coil spring disposed in the hollow portion 50 a of the slider 50, one end of which is attached to the spring receiving portion 50 c of the slider 50 and the other end is attached to the link 40. The second spring 62 urges the link 40 in the direction in which the link 40 is in the allowable position, that is, in the direction in which the blocking portion 43 is separated from the camshaft 20 (upward in FIG. 6).

  The cylinder lock 70 is a key cylinder configured to transmit the rotation of the key to the camshaft 20 when the key is rotated in a state of being engaged with the camshaft 20, and is housed in the housing 10. ing. The cylinder lock 70 includes a cylinder outer 71 fixed to the housing 10, a cylinder inner 72 that can rotate within the cylinder outer 71, and a key insertion hole 73 that is opened at the end of the cylinder inner 72. .

The ignition switch 80 is attached to the end of the housing 10 and the switch engaging portion 23 of the camshaft 20 is engaged. When the camshaft 20 is rotated, the rotation is transmitted into the ignition switch 80.

The lock shaft 94 is movably attached integrally with the lock slider 93, and the lock shaft 94 and the lock slider 93 are urged by a spring 92 toward the lock position where the lock shaft 94 protrudes. The lock slider 93 has an opening 93a at the center, and the camshaft 20 passes through the opening 93a. The shape in the opening 93a is adapted to engage with the lock driving portion 24 of the camshaft 20, and the lock slider 93 and the lock shaft 94 move forward and backward according to the rotational position of the camshaft 20.

  The steering lock device 1 of the present embodiment described above can easily assemble the lock drive mechanism 90, the interlocking mechanism, and the solenoid 30, and has high safety against unauthorized disassembly. Hereinafter, this point will be described.

  The lock driving mechanism 90 is configured to cover the spring 92, the lock slider 93, and the lock shaft 94 with the lid 91 in a state where the spring 92, the lock slider 93, and the lock shaft 94 are housed in the housing portion 15 of the first housing portion 10A. Is housed in the housing portion 15. The lid 91 is fixed to the housing 10 with a pin 95 inserted into the pin hole 91a.

After the lock drive mechanism 90 is assembled, the solenoid 30 is a security screw in a state in which the interlocking mechanism (link 40, slider 50, first spring 61, and second spring 62) is housed in the accommodating portion 13. A one-way bolt 32 is fixed to the housing 10 by passing through the hole 30c and being fastened to the mounting hole 13a.
Since the solenoid 30 is attached, the cover portion 30b covers the opening portion 13d other than the portion corresponding to the through portion 30d. However, in this state, a portion of the link 40 is still exposed through the through portion 30d. The penetrating part 30d, the engaging part 42 of the link 40 exposed from the penetrating part 30d, and the plunger 31 are covered and accommodated by the case 14.

Further, the solenoid 30 is arranged so that a part thereof covers the lid 91.
The solenoid 30 is fixed to the housing 10 by the one-way bolt 32 passing through the hole 30c and being fastened to the mounting hole 13a. With this configuration, it is difficult to remove the solenoid 30, and it is also difficult to remove the lid 91, which increases the safety against unauthorized destruction. One-way bolts are illustrated as security screws, but in addition to these, ones that cannot be removed once they are assembled, or that cannot be removed due to unauthorized removal, or special tools are used. Otherwise, it is possible to use one that is very difficult to remove. In addition, since a part of the solenoid 30 covers the lid 91, the safety against an illegal destruction act on the lock driving mechanism 90 is also high.

As described above, according to the first embodiment, there is no need to perform press-fitting, caulking, etc., so no additional equipment is required, and the solenoid 30 can be fixed by screw tightening, so that only a screwdriver is required for the jig. In addition, assembly is possible with simple equipment, and the number of assembly steps can be reduced and the cost can be reduced.
Further, since the solenoid 30 is placed over the lid 91 of the steering lock device 1, the solenoid 30 becomes an obstacle and it is difficult to perform an unauthorized attack on the lid 91. Therefore, the anti-theft property is improved.
Furthermore, since the case 14 that covers a part of the interlocking mechanism and the plunger 31 is provided, the drive unit can be protected, and entry of dust, water, and the like into the apparatus can be prevented.
Furthermore, since the one-way bolt is used for fixing the solenoid 30, it is difficult to remove it once the solenoid 30 is tightened and fixed, and the anti-theft performance is improved without changing the number of parts.
