Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIGS. 1 to 4, the steering lock device according to the first embodiment includes a lock device main body 1 as a housing, and a lock bar 2 that can project or immerse into the lock device main body 1. A push button 3 disposed in a state of protruding upward from the upper surface of the lock device main body 1 and capable of being pressed, a locking member 10 as a lock means, a second gear G2 as an electric lock release means, It is mainly comprised by the rotation member 6 as a manual unlocking means.

  The push button 3 is composed of a rotor 4 into which an ignition key IK (see FIG. 6) can be inserted, and has a cap 5 disposed at a protruding end of the rotor 4. A plurality of tumblers (not shown) are formed on the rotor 4 along the key holes. In a normal state (a state where the ignition key IK is not inserted), the tumblers are engaged with the inner wall of the lock device main body 1. The rotation is restricted, and when the ignition key IK is inserted, the tumbler is immersed and can rotate around its axis.

  A rotating member 6 and a slide member 7 are disposed below the push button 3. When the push button 3 is pressed in the direction of the arrow in FIG. 4, the slide member 7 descends against the urging force of the coil spring S1. In addition, when the ignition key IK is inserted into the rotor 4 and rotated in this state, the rotating member 6 is interlocked to rotate against the urging force of the torsion spring S4. A groove 7a is formed in the side surface of the slide member 7 along the axial direction thereof, and a protrusion (not shown) on the side of the lock device main body 1 is fitted into the groove 7a. The member 7 is allowed to slide and its rotation is restricted.

  A pair of link members 8 extend from both side surfaces of the slide member 7, and a stay 9 is connected to the other end side of these link members 8. The stay 9 is provided with a lock bar 2 via a coil spring S2. When the slide member 7 slides downward by the pressing operation of the push button 3, the stay 9 and the lock bar 2 are steered by the action of the link member 8. It is comprised so that it may move to the engagement hole H side formed in the axis | shaft.

  That is, as shown in FIGS. 4 and 5, the stay 9 and the lock bar 2 move as the slide member 7 slides downward, and the tip of the lock bar 2 enters the engagement hole H and engages. The steering shaft can be locked. If the lock bar 2 is not in a position facing the engagement hole H, the coil spring S2 can be compressed to restrict the movement of the lock bar 2 even if the stay 9 is moved by the pressing operation of the push button 3. Overload on the shaft can be avoided. In this state, if the steering is turned to a lockable position (position where the engagement hole H faces the lock bar 2), the lock bar 2 can be engaged with the engagement hole H by the biasing force of the coil spring S2. it can.

  The locking member 10 (locking means) is for locking the lock bar 2 in the state of entering the engagement hole H as described above and maintaining the locked state of the lock bar 2, and is always driven by the coil spring S3. It is biased downward. As a result, when the stay 9 is moved by the pressing operation of the push button 3, the locking member 10 biased by the coil spring S3 is lowered, and the tip of the engaging member 10 and the base of the stay 9 are moved as shown in FIG. The end side is engaged and locked. The locking member 10 is formed with an electric-side convex portion 10a that protrudes toward the gear G2, which will be described later, and a manual-side convex portion 10b that protrudes toward the rotating member 6.

  As shown in FIG. 2, the motor M has an output shaft Ma, and a gear G1 meshes with the output shaft Ma. Further, the gear G1 is disposed so as to mesh with the gear G2 adjacent to the electric-side convex portion 10a of the locking member 10, and by driving the motor M, the gear G2 can be rotated via the gear G1. Yes. Here, a bulging portion (not shown) is formed on the surface of the gear G2 to abut on the electric-side convex portion 10a of the locking member 10 by the rotation of the gear G2 and pull it upward.

  Accordingly, when the motor M is driven to rotate the output shaft Ma, the G2 rotates via the gear G1, and the locking member 10 can be moved upward against the urging force of the coil spring S3. The tip of the locking member 10 is separated from the stay 9 and the lock at the lock position of the lock bar 2 is released. In such a state, the slide member 7 and the push button 3 are moved upward by the urging force of the coil spring S1, and the stay 9 and the lock bar 2 are returned to the initial state (the state of FIG. 4) by the movement. Therefore, the steering lock is released.

  By the way, as shown in FIG. 7, the two-wheeled vehicle applied to the present embodiment includes a transmission means 11 that can be carried by the driver and transmits a vehicle-specific ID code, and is disposed on the vehicle side and is transmitted from the transmission means. Receiving means 12 capable of receiving an ID code. The transmission means 11 includes, for example, a transmission antenna that can transmit an ID code unique to a specific two-wheeled vehicle and a card-type electronic key that has a built-in power source such as a battery. It is designed to transmit wirelessly.

  As a result, when the driver approaches the motorcycle while carrying the transmission means 11, the reception antenna of the reception means 12 can receive the ID code. When the receiving means 12 receives the ID code from the sending means 11, it is determined whether or not the ID code is a proper ID code unique to the motorcycle, and by recognizing that the ID code is a proper ID code. The motor M is configured to be driven. The receiving antenna of the receiving means 12 constitutes a part of the CAN disposed in the two-wheeled vehicle, and is electrically connected to the CAN for controlling the driving of the motor M.

  That is, when the person carrying the transmission means 11 approaches the motorcycle, it is determined whether or not the ID code transmitted from the transmission means 11 is a regular one. Thus, the lock bar 2 is unlocked by the locking member 10 and the lock bar 2 is separated from the engagement hole H. Therefore, the steering lock is released electrically and automatically, and it can be easily applied to, for example, a keyless entry system.

  Here, in the present embodiment, in addition to the electrical steering lock release as described above, the steering lock can be manually released with the ignition key IK. Specifically, as shown in FIGS. 6 and 8, when the cap 5 on the protruding end side of the push button 3 is opened and the ignition key IK is inserted into the rotor 4, the internal tumbler is immersed as described above. The rotor 4 is rotatable. When the ignition key IK is rotated from this state, the rotating member 6 rotates together with the rotor 4 against the urging force of the torsion spring S4, and a convex portion (not deformed) formed on the flange portion of the rotating member 6 is detected. (Shown) presses the manual convex portion 10b of the locking member 10 upward.

  As a result, the locking member 10 moves upward against the biasing force of the coil spring S3, the tip of the locking member 10 is separated from the stay 9, and the lock at the lock position of the lock bar 2 is released. Will be. In this state, the slide member 7 and the push button 3 are moved upward by the urging force of the coil spring S1, and the stay 9 and the lock bar 2 are returned to the initial state (state shown in FIG. 4) by the movement, and the steering is The lock is released.

  Accordingly, in a normal state, the steering lock can be released electrically by the motor M, so that the operability can be improved and the ID code cannot be transmitted due to the power consumption of the transmission means 11 or the like. Even in this case, the steering lock can be manually released by rotating the push button 3 through which the ignition key IK is inserted, and emergency measures such as temporary saving of the motorcycle can be facilitated. Note that after the push button 3 is rotated, the push button 3 returns to the initial position by the biasing force of the torsion spring S3.

  Further, according to the present embodiment, since the cap 5 is disposed at the projecting end of the push button 3, the cap 5 is closed in a normal state, thereby facilitating a pressing operation at the time of steering lock. However, intrusion of foreign matter, rainwater, etc. into the rotor 4 can be avoided, and when the electric steering lock cannot be released, the cap 5 can be opened and the ignition key IK can be inserted to manually release the steering lock. Can be made.

Next, a second embodiment according to the present invention will be described.
As shown in FIGS. 9 to 11, the steering lock device of the present embodiment includes a lock device main body 1 as a housing, a lock bar 2 that can project or immerse into the lock device main body 1, and a lock device main body. 1. A push button 3 that is disposed in a state of projecting upward from the upper surface of 1 and that can be pressed, a locking member 13 as a lock means, a cam gear 14 as an electric lock release means, and a manual lock release means The rotation member 6 is mainly configured. In addition, the same code | symbol shall be attached | subjected to the component similar to the said 1st Embodiment, and those detailed description is abbreviate | omitted.

  However, as in the first embodiment, by pressing the push button 3 downward, the slide member 7 is lowered against the biasing force of the coil spring S1, and the stay 9 and the lock bar 2 are moved by the action of the link member 8. If the lever is moved toward the engagement hole H (see the first embodiment) formed in the steering shaft (the lock bar 2 protrudes), the steering shaft is locked. At this time, the locking member 13 goes from the state shown in FIG. 13A through the state shown in FIG. 13B to the state shown in FIG. It engages with the end (the right end in the figure), and the state (locked state) engaged with the steering shaft of the lock bar 2 is maintained.

  Similarly to the first embodiment, when the cap 5 is opened and the ignition key IK is inserted into the rotor 4 and rotated in this state, the rotating member 6 is interlocked to resist the biasing force of the torsion spring S4. And a convex portion (not shown) formed on the flange portion of the rotational member 6 presses the concave portion 13a of the locking member 13 upward. As a result, the locking member 13 moves upward against the biasing force of the coil spring S3, and the distal end of the locking member 13 is separated from the base end of the stay 9, so that the slide member 7 and the push button 3 are moved to the coil spring S1. The urging force moves upward to return to the state shown in FIG. 10, and the steering lock is released.

  Here, in the present embodiment, the cam gear 14 as the electric lock means is disposed in connection with the motor M as the drive means. As shown in FIG. 11, the cam gear 14 is disposed so as to mesh with the output shaft Ma of the motor M, and can be rotated about the rotation axis L by driving the motor M. As shown in FIG. 2, a concave groove 14a is formed on the surface. A convex portion 13b protruding from the locking member 13 is fitted into the concave groove 14a, and the convex portion 13b can be moved along the peripheral shape of the concave groove 14a by rotating the cam gear 14. Has been.

  However, the cam gear 14 according to the present embodiment has a manual operation allowable position (position in FIG. 12) that allows manual unlocking by rotating the ignition key IK, and an electric unlocking position that allows the motor M to unlock ( It is possible to rotate between the position of FIG. 14 and a pressing operation restricting position (position of FIG. 15) that restricts the pressing operation of the push button 3.

  When the cam gear 14 is in the manual operation allowable position in the locked state of the steering, when the ignition key IK inserted through the rotor 4 is rotated, the locking member 13 is pressed upward, and the tip of the locking member 13 stays at the stay 8. The state moves from the state engaged with the base end of the member (state shown in FIG. 13C) to the state separated (state shown in FIG. 13B). At this time, the convex portion 13b of the locking member 13 moves from the position shown in FIG. 12A to the position shown in FIG. 12B in the concave groove 14a.

  When the distal end of the locking member 13 is separated from the base end of the stay 9, the slide member 7 and the push button 3 are moved upward by the biasing force of the coil spring S 1, so that the stay 9 is moved together with the lock bar 2 in the immersion direction. The state shown in FIG. 13B is changed to the state shown in FIG. 13A (the end of the locking member 13 is positioned in the recess 9a of the stay 9), and the steering lock is released. Therefore, if the cam gear 14 is in the manual operation allowable position in the steering lock state, unlocking by rotating the ignition key IK inserted through the rotor 4 is permitted.

  On the other hand, when the person carrying the transmission means 11 (see the first embodiment) approaches the two-wheeled vehicle in the steering locked state, and the ID code transmitted from the transmission means 11 is genuine, the motor M is driven. Thus, the cam gear 14 is configured to rotate to the electric lock release position. That is, when the motor M is driven to rotate the cam gear 14 in the direction a in FIG. 12 (forward rotation), as shown in FIG. 14, the convex portion 13b of the locking member 13 is moved to one end 14aa of the concave groove 14a. In this process, the convex portion 13b moves upward, so that the tip of the locking member 13 is separated from the concave portion 9a, and the steering lock is released.

  Further, when the steering lock is released and the vehicle starts to travel, the motor M is driven and the cam gear 14 is rotated (reversely rotated) in the direction b in FIG. Thus, since the cam gear 14 rotates to the pressing operation restriction position, the convex portion 13b of the locking member 13 reaches the other end 14ab of the concave groove 14a, and the convex portion 13b moves downward. ing.

  As a result, the tip of the locking member 13 is further lowered in the recess 9a of the stay 9 and is in the state shown in FIG. 5B, so that the stay 9 moves (moves in the direction in which the lock bar 2 protrudes). It can be regulated by the tip of the locking member 13, and the pushing operation of the push button 3 is regulated. In other words, when the cam gear 14 is in the manual operation allowable position, the push button 3 can be pushed so that the distal end of the locking member 13 can ride on the upper surface from the recess 9 a of the stay 9 and reach the proximal end of the stay 9. On the other hand, when in the pressing operation restricting position, the tip of the locking member 13 is lowered so that it cannot climb onto the upper surface from the recess 9a of the stay 9, and the pressing operation by the push button 3 is restricted. -ing

  By the way, the motor M according to the present embodiment includes a stepping motor, and it is easy to stop the cam gear 14 at a predetermined position. That is, the stepping motor is normally out of synchronization (power transmission is interrupted) when a load of a certain level or more is applied to the output shaft, and can be stopped at that position. Or if it rotates to a press operation control position and the convex part 13a of the latching member 13 contact | abuts to the one end 14aa or the other end 14ab of the ditch | groove 14a and a load is applied, the drive of the motor M will stop and those positions will be stopped. Thus, the cam gear 14 can be stopped.

  Therefore, according to the present embodiment, the cam gear 14 is rotated by a predetermined angle using the stepping motor, and the convex portion 13a of the locking member 13 is moved between the one end 14aa and the other end 14ab of the concave groove 14a. Therefore, as compared with the case where the second gear G2 needs to be rotated once as in the first embodiment, the cam gear 14 rotates between the manual operation allowable position, the electric lock release position, and the pressing operation restriction position. It can be done more quickly.

  In addition, a magnet 14a is formed at a predetermined portion of the cam gear 14, and a Hall IC element (not shown) for detecting the magnetism of the magnet 14a is disposed on the lock device body 1 side. The magnet 14a and the Hall IC element constitute cam gear detection means. Such a Hall IC element is disposed so as to face the magnet 14a when the cam gear 14 is in the manual operation allowable position (the state shown in FIG. 12), and is turned on by detecting the magnetism. Then, when in the electric unlocking position or the pressing operation restricting position (the state shown in FIG. 14 or 15), the magnet 14a is separated and turned off.

  Therefore, the positioning of the electric lock release position and the pressing operation restriction position of the cam gear 14 is performed when the convex portion 13a of the locking member 13 contacts the one end 14aa or the other end 14ab of the concave groove 14a, while the manual operation allowable position. Since the Hall IC element can detect the magnetism of the magnet 14b, the positioning accuracy of the cam gear 14 can be improved. It may be configured to detect that the cam gear 14 is in the electric unlocking position or the pressing operation restricting position. In this case, for example, when it is detected that the cam gear 14 is not in the pressing operation restricting position during vehicle travel, It is preferable to notify the driver and call attention.

  According to the present embodiment, the cam gear 14 is rotated between the manual operation allowable position, the electric lock release position, and the pressing operation restricting position by driving the motor M, thereby locking the ignition key IK by the rotation operation. Since the release permission, the lock release by the motor M, and the restriction of the pressing operation of the push button 3 can be selectively performed, the steering lock is released electrically, and the steering lock is also released manually. In addition, for example, it is possible to avoid pressing the push button 3 by mistake during traveling of the vehicle.

  Further, in the steering lock device according to the present embodiment, a magnet (not shown) is formed on the base end side of the lock bar 2 and the lock device main body 1 side is for detecting the magnetism of the magnet. A Hall IC element 15 (see FIG. 10) is provided, and these magnets and the Hall IC element 15 constitute a lock bar detecting means. The Hall IC element 15 is disposed so as to face the magnet when the lock bar 2 is in an immersive state (position away from the steering shaft), and is turned on by detecting the magnetism. Is in the protruding state (position where the steering shaft is locked), the magnet is separated and turned off.

  The lock bar detecting means can detect whether the lock bar 2 is in a position where the steering shaft is locked or separated, so that the lock bar malfunctions due to forgetting the steering lock or malfunction of the device, for example. Can be detected. In particular, in this embodiment, when the lock bar 2 is not in a position facing the engagement hole H, the coil spring S2 is compressed to restrict the movement of the lock bar 2 even if the stay 9 is moved by the pressing operation of the push button 3. And since the overload with respect to a steering shaft is avoided, this state can be detected by a lock bar detection means, for example, a driver can be notified by a warning or the like.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, instead of the ignition key inserted through the rotor 4, a dedicated key for releasing the steering lock may be used, or the locking member 10 may be attached to the stay member. Instead of the motor M separated from the motor 9, other electric drive means (general-purpose actuator or the like) may be used. Further, the transmitting means may be a remote controller that transmits infrared rays, etc., and may receive the infrared rays and drive electric driving means such as the motor M to release the steering lock. Furthermore, although this embodiment is applied to a two-wheeled vehicle, it can also be applied to other vehicles (such as buggies and snow vehicles) that require a steering lock.

  Still further, the lock bar detection means and the cam gear detection means in the second embodiment are composed of a magnet and a Hall IC element, but instead of this, the position where the lock bar locks or separates the steering shaft. It is good also as a lock bar detection means of the other form which detects in any of these, or a cam gear detection means of the other form which can detect the rotation position of a cam gear.

  If the steering lock device can be unlocked manually by releasing the lock by the electric drive means and rotating the push button through which the key is inserted, the one with a different external shape or other function is added It can also be applied to what has been done.
