Description

[Detailed description of the invention] (Field of industrial application) The present invention is a steering lock device for a vehicle in which the steering shaft of the steering wheel is locked unrotatably by a cylinder lock that operates an electric switch of an automobile engine. In particular, the present invention relates to a mounting structure for a switch used to detect a push-in operation of a cylinder lock rotor.

(Prior art) In a vehicle steering lock device in which the steering shaft of the steering wheel is locked unrotatably by a cylinder lock, the steering wheel may be accidentally locked while the vehicle is driving due to the driver misoperating the key. There needs to be a way to prevent this from happening. Conventionally, mechanisms that meet this requirement have been designed so that the key cannot be rotated to the lock position only by turning the key without pressing the key, and cannot be rotated to the lock position while driving even if the key is pressed. To,
A blocking member activated by both a signal from a sensor that detects that the vehicle is in a running state and a switch that detects a pushing operation of the cylinder lock rotor in the ACC position is engaged with the cylinder lock rotor to prevent the cylinder from moving. Mechanisms are known which prevent the lock rotor from rotating into the locked position.

Among the above mechanisms, the present invention relates to a switch that detects the pushing operation of the cylinder lock rotor. The switch that detects the push-in operation of the cylinder lock rotor must reliably detect the push-in operation of the cylinder lock rotor for the reasons mentioned above.In order to do this, the switch must be installed inside the steering lock device, and the switch must be installed inside the steering lock device. It is desirable that the switch itself be pressed directly against the switch actuating part of the switch.

(Problems to be Solved by the Invention) However, since there is not enough space inside the steering lock device for a vehicle to incorporate the above-mentioned switch, the switch has to be mounted on the outside of the device. As a result, the switch will be exposed to the outside, creating a risk of damage to the switch. Further, since the cylinder lock rotor and the switch operating portion of the switch are located apart from each other, an intermediate member is required to operate the switch. Therefore, there is a risk that dust or the like may enter through the insertion hole through which the intermediate member is inserted into the device, causing malfunction of the steering lock device. Furthermore, since the lead wires of the switch are exposed to the outside, there is a drawback that the direction in which the lead wires are drawn out is unstable.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems, and as a means thereof, a push-in operation of the cylinder lock rotor installed in the body of the steering lock device is used. A protruding rod extending inward is provided on one side of the first switch cover that covers the switch for detecting the switch, and the protruding rod is fitted into a fitting hole provided in the body to attach the switch to the side surface of the body. At the same time, the switch is fixed to the body by inserting a screw into a screw hole provided on the other side of the first switch cover, and the first switch cover accommodates a lead wire of the switch. The switch has a concave groove, and a second switch cover for covering the concave groove and holding the lead wire is fitted therein.

On the other hand, as shown in FIG. 2, a mounting portion 10 for mounting the above-mentioned switch unit 1 is formed on the outside of the body 9 of the steering lock device. The mounting portion 10 includes a convex portion 11 for inserting into the insertion hole 8 formed in the base body 3 when the switch unit 1 is mounted, a swinging piece 5 pivotally supported on the base body 3, and the like. An insertion hole 12 for inserting the end pressing portion 5b into the body 9 is formed. Incidentally, a screw groove (not shown) is cut inside the convex portion 11, and after the switch unit 1 is mounted on the mounting portion 10 and a first switch cover 14, which will be described later, is covered from above, the switch unit 1 is fixed by screwing. It is made possible.

As shown in FIG. 3, the pressing part 5b of the rocking piece 5 inserted through the insertion hole 12 extends in the circumferential direction around the outer periphery of the cylinder lock rotor 20, which is built into the body 9 and can be pushed only in the ACC position. cam surface 21
It is designed to engage with Further, the cylinder lock rotor 20 is provided with an engaging protrusion 24 that can engage with a protruding cam 23 provided on the rear end surface of the outer cylinder 22 in the ACC position. 20 is not rotated to the locked position, but requires a push-in operation. When the cylinder lock rotor 20 is in the normal position, the pressing portion 5b of the swing piece 5 is pressed against the cam surface 21 of the cylinder lock rotor 20, and at this time the switch 2 is in the OFF state (in the OFF state).

Further, as shown in FIG. 7, a solenoid 28 attached near the body 9 of the steering lock device is a detection sensor that turns on the switch 2 by pushing the cylinder lock rotor 20 and detects the running state. (not shown) is energized when activated, and the plunger 29 is attracted by the energization of the solenoid 28. The plunger 2
The locking portion 31a on the other end side of the lever 31, which has one end connected to the cylinder lock rotor 9 and is pivotally supported by the shaft 30, locks the cylinder lock rotor 20 when the cylinder lock rotor 20 is rotated to the lock position after the push operation at the ACC position. The cylinder lock rotor 20 is engaged with an engaging protrusion 24 provided in a protruding manner to prevent the cylinder lock rotor 20 from rotating to the lock position.

Next, the operation of this embodiment will be explained.

Since the cylinder lock rotor 20 rotates to the lock position while traveling, when the cylinder lock rotor 20 is pushed in at the ACC position, the engagement between the cam surface 21 and the pressing portion 5b of the rocking piece 5 is released. Switch 2 is turned on. As a result, the solenoid 28 is energized and attracts the plunger 29, and the locking portion 31a of the lever 31 connected to the plunger 29 moves to the rotation blocking position of the cylinder lock rotor 20. As a result, the locking portion 31a of the lever 31 and the engagement protrusion 32 of the cylinder lock rotor 20 engage with each other, thereby preventing the cylinder lock rotor 20 from rotating to the lock position.

In this embodiment, the lead wires 16a and 16b accommodated in the grooves 15a and 15b are drawn out and wired, but the second switch cover 18 that holds the lead wires 16a and 16b is connected to the first switch cover. 14, the lead wire 1 is held by the pinching action of both the switch covers 14 and 18.
This has the effect of reliably fixing the drawing directions of 6a and 16b.

(Effects of the Invention) As described above, the present invention provides a first switch that covers a switch that is attached to the outside of the case in order to detect the pushing operation of the cylinder lock rotor that is housed in the body of the steering lock device. A protruding rod extending inward is provided on one side of the cover, a screw hole is provided on the other side, the protruding rod is fitted into a fitting hole provided in the case, and a screw is inserted through the screw hole. Since the first switch cover is fixed by tightening the screws,
