Definitions
- the present invention relates to an electric steering lock device that is mounted on an automobile or the like and includes a so-called deadlock mechanism.
- the electric steering lock device 100 includes a frame 101 and a cover (not shown) that covers the upper surface of the frame 101.
- the frame 101 includes a frame main body 102 and a rod guide portion 103 protruding from the frame main body 102.
- a drive motor (not shown) controlled by the operation of the ignition key of the person carrying the electronic key, and a cam that rotates by the drive of the drive motor.
- Members (not shown) and the like are accommodated.
- a lock rod 105 whose upper end protrudes on the frame body 102 is movably accommodated.
- the lock rod 105 is composed of an upper rod portion 105a and a lower rod portion 105b connected to the upper rod portion 105a, and is configured to lock the steering shaft 110 by the rotation of the cam member (not shown). 1) and the unlocked position (position in Fig. 2) allowing the steering shaft 110 to rotate.
- the deadlock mechanism 120 includes a lock pin 121 housed in a position below the fragile portion 106 of the rod guide portion 103, a first spring 122 that urges the lock pin 121 in the protruding direction, and a lock pin 121 A lock control member 123 that restricts movement in the protruding direction, a second panel 124 that urges the lock control member 123 upward, and a stopper 125 on the frame body 101 side that restricts upward movement of the lock control member 123. And first and second locking grooves 126 and 127 formed in the upper rod portion 105a.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2004-231122
- the deadlock mechanism 120 of the conventional electric steering lock device 100 allows the person who performs unauthorized unlocking to apply an external force exceeding a predetermined value to the rod guide portion 103 and the lock rod 105. It works only for illegal attacks that act. Therefore, if a cover (not shown) is illegally attacked without applying an external force exceeding a predetermined value to the rod guide portion 103 and the lock rod 105, the rod guide portion 103 and the lock rod 105 do not operate. If the cover (not shown) is removed from the frame body 102 in a state where the deadlock mechanism 120 is not activated, the possibility of unauthorized unlocking increases, and this must be prevented.
- the cover in order to deal with an illegal attack on the cover, it is considered that the cover can be configured with a very strong member in terms of force S, weight, and cost. At the same time, there is a limit to the structure for preventing the cover from breaking. Therefore, it is not satisfactory as a means of dealing with illegal cover attacks.

- a trigger member that prevents movement of the trigger member when the cover moves in a direction away from the frame.
- the lock pin is configured to shift in a pin releasing direction so that the lock pin is locked to the locking portion, and the cover is surrounded by a portion that surrounds the fixed portion of the trigger member and the frame.
- an electric steering lock device in which a weak portion is provided at a peripheral portion of the door.
- a second aspect of the present invention is a drive mechanism portion on a frame covered with a cover, and a lock rod that is automatically disposed in a rod guide hole of the frame, and is provided by the drive mechanism portion.
- a mechanism that is moved between a steering lock position and a steering unlock position, and a deadlock mechanism that locks the lock rod in a steering lock position, and the deadlock mechanism is provided in the lock rod.
- a locking member that is disposed on the frame side and is urged toward the locking position to be locked to the locking portion; and a trigger member that is fixed to the cover and prevents movement of the locking pin to the locking position And when the cover moves in the direction of detachment from the frame, the trigger member force S changes in the pin release direction, Kkupin with is configured to lock with the locking portion, said cover to provide an electric stearyl ⁇ ring-locking device is also configured strength weaker than the frame.
- the cover may be formed of a material that is weak in strength, it contributes to weight reduction and cost reduction.
- At least one of the surfaces of the trigger member and the lock pin that contact each other may be provided on a tapered surface.
- the urging force that urges the lock pin toward the lock position causes the taper surface to be urged.
- the trigger member moves in the pin release direction because it acts on the trigger member via the lock pin force S locks the lock rod. Therefore, it is possible to cope with an illegal attack before the cover is removed from the frame or when the cover is not removed from the frame.
- the weak portion of the force bar provided in the vicinity of the fixed portion of the trigger member is provided in a portion surrounding the spring receiving portion that urges the lock rod toward the steering lock position. You may do it.
- the cover may be made of synthetic resin and the trigger member may be formed in a body.

For this reason, when trying to make a hole in a part of the cover 3 in the vicinity of the lock rod 14, the force S at which a part of the cover 3 easily breaks along the inner fragile part 7, a fragment of this force bar 3
- the trigger member 25 and the spring receiving portion 6 are attached to the door. Accordingly, when a part of the cover 3 is broken, the trigger member 25 is immediately moved in the pin releasing direction a by the urging force of the rod panel 16, and the lock pin 23 locks the lock rod 14. Therefore, it is possible to cope with an illegal attack that makes a hole in a part of the cover 3.
- the cover 3 is made of synthetic resin, and the trigger member 25 is formed into a body. For this reason, the trigger member 25 can be easily manufactured by integrally forming the trigger member 25 during the injection molding of the cover 3.
- the other embodiment is different from the cover 3 of the above embodiment in that the cover 3 itself is configured to be weak in strength.
- the configuration other than the cover is the same as that of the above embodiment.
- the cover when a person who performs unauthorized unlocking attacks the cover, the cover is easily deformed / damaged and removed from the frame.
- the trigger member moves in the pin releasing direction at that time, and the lock pin locks the lock rod. Therefore, it is possible to reliably deal with unauthorized attacks that open the cover illegally, and it has excellent anti-theft performance.
- a mechanical electric steering lock that moves the lock rod 14 by using the operation force of the mechanical key force as the power when the present invention is applied to the electric steering lock device 1
- it can also be applied to the apparatus.
