Description

  The present invention relates to a steering lock device that performs a steering lock by manual operation and releases the steering lock electrically.

  In order to prevent theft of vehicles that frequently occur in recent years, the vehicle includes a transmission unit that can transmit a vehicle-specific ID code while being carried by a driver, and a reception unit that can receive the ID code. A so-called smart entry system has been proposed that allows various operations of the vehicle including engine start, provided that the ID code is genuine. For example, in the case of a smart entry system in a two-wheeled vehicle, when the driver carrying the transmission means (electronic key) approaches the vehicle, the reception means receives the ID code transmitted from the transmission means, and is registered in advance. It is determined whether or not there is.

  When it is determined that the ID code is valid and the driver presses an access button or the like provided on the vehicle, the vehicle is turned on and the engine is operated by pressing the start button or the like. It is configured to be started. As a result, various operations of the vehicle including the engine start can be performed without using a mechanical key such as an ignition key, and theft of the vehicle or unauthorized operation of the vehicle can be reliably prevented. it can.

  However, in a two-wheeled vehicle or the like, usually, a steering lock that locks a steering bar (such as a rotating shaft of a handlebar) by locking a lock bar by rotating an ignition key inserted through a key hole in a predetermined direction. However, it has been difficult to apply to a device equipped with a smart entry system that does not require the operation of the ignition key as described above.

Therefore, the present applicant has proposed a steering lock device as disclosed in Patent Document 1, for example. According to such a conventional steering lock device, the steering lock is performed by manual operation by pressing the push button and the steering lock is released electrically. A mechanical key can be dispensed with and can be easily applied to a smart entry system.

  However, the conventional steering lock device has the following problems. That is, since the engine is not started unless a proper ID code is received, the vehicle can be prevented from being stolen, but the push button for locking the steering wheel and the lock bar are always interlocked. There is a risk that the lock bar is forcibly released by forcibly operating the push button.

  The present invention has been made in view of such circumstances, and provides a steering lock device that can improve the operability without requiring an operation with a mechanical key or the like, and can further improve the anti-theft effect. It is in.

  The invention according to claim 1 is a transmitting means for transmitting a vehicle-specific ID code that can be carried by the driver, a receiving means disposed on the vehicle side for receiving the ID code from the transmitting means, and the reception Determining means for determining whether or not the ID code received by the means is genuine, and the push operation changes the protruding state to the immersive state, locking the lock bar to the vehicle steering and locking the steering. On the condition that the operating member is separate from the operating member, the cover member is provided so as to cover the outer surface of the operating member, and the determination means determines that the correct ID code has been received. An electric release means for releasing the steering lock by releasing the locking of the lock bar with the steering by bringing the operation member in the immersed state into the protruding state. In accordance with the pressing of the cover member, the operation member moves from the projecting state to the immersive state, and the operation member is in the direction from the immersive state to the projecting state. Does not follow the cover member.

  According to a second aspect of the present invention, in the steering lock device according to the first aspect, a link member for connecting the operation member and the lock bar is provided, and the operation member and the lock bar are interlocked via the link member. It is characterized by that.

  According to the first aspect of the present invention, the steering lock is released by manual operation of the operation member, and the motor is driven by the electric release means on the condition that it is determined that the proper ID code has been received and the steering lock is released. Therefore, the operability can be improved by eliminating the need for an operation with a mechanical key or the like. At the same time, the operating member moves from the protruding state to the immersive state following the pressing of the cover member, and the operating member does not follow the cover member in the direction from the immersive state to the protruding state of the operating member. The antitheft effect can be further improved.

  According to the invention of claim 2, since the operating member and the lock bar are linked via the link member, the manual operation on the operating member at the time of steering lock can be performed more smoothly and reliably.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The steering lock device according to the present embodiment is applied to a two-wheeled vehicle, and performs steering lock by manual operation and electrically releases the steering lock, and is carried by a driver as shown in FIG. And transmitting means 2 for transmitting the ID code unique to the vehicle, receiving means 3 disposed on the vehicle side for receiving the ID code from the transmitting means 2, and the ID code received by the receiving means being normal. It is mainly comprised from the determination means 4 which determines whether it is these, and the lock mechanism 1 which performs steering lock or steering lock cancellation | release.

  The transmission means 2 can always transmit an ID code by radio waves or the like, and is configured such that when the driver carrying the transmission means 2 approaches the vehicle, the reception means 3 on the vehicle side can receive the ID code. ing. The determination unit 4 compares the ID code registered in advance with the ID code received by the reception unit 3 and determines that a regular ID code has been received if they match.

  Further, as shown in the figure, the determination means 4 is electrically connected to an access button 5 and a start button 6 formed at a predetermined position of the vehicle (in the vicinity of the meter panel, etc.), and the reception means 3 is properly connected. When it is determined that the ID code has been received and the access button 5 is operated, the vehicle is turned on and the lock mechanism 1 is instructed to release the steering lock.

  The vehicle engine E can be started when it is determined that the receiving means 3 has received a legitimate ID code and the start button 6 is operated after the access button 5 is operated. . Therefore, when the driver approaches the vehicle and the receiving means 3 receives the proper ID code, the power can be turned on and the engine can be started without operating the mechanical keys and the like, and the operability is improved. be able to.

  As shown in FIGS. 1 to 3, the lock mechanism 1 includes a main body 9 having a lid portion 9 a formed thereon, an operation member 10 movable in the vertical direction within the main body 9, and an outer side of the operation member 10. Cover member 7 provided so as to cover the surface, spring 11 provided at the lower part of operation member 10, lock bar B which can be moved in and out from main body 9, and link member which connects operation member 10 and lock bar B 12 and a motor 8. In addition, the code | symbol 9b in the figure has shown the bracket part for attaching the main body 9 to a vehicle.

  The operation member 10 is lowered by being pressed through the cover member 7, and is changed from the protruding state (the state shown in FIG. 3) to the immersed state (the state shown in FIG. 4). That is, when the cover member 7 is pressed and lowered, the operation member 7 also follows and descends against the urging force of the spring 11. The immersion state of the operation member 7 is maintained by a locking member 17 described later.

  The lock bar B is composed of a rod-like member that is slidable between a retracted position (state shown in FIG. 3) and a protruding position (state shown in FIG. 4) as the operating member 7 is operated. The steering can be locked by locking with a steering of a vehicle (not shown) (specifically, a turning shaft of a handlebar in a two-wheeled vehicle), and the sliding to the reverse position is released to release the locking with the steering. The lock can be released.

  As shown in FIG. 6, the link member 12 is composed of a pair of left and right plates whose one end is connected to a pin 13 formed on the operation member 10 and whose other end is connected to a pin 14 formed on the lock bar B. Is. The operation member 10 and the lock bar B are connected by the link member 12 so that the operation member 10 and the lock bar B can be interlocked. That is, when the operation member 10 is lowered from the protruding state (refer to FIG. 3) to the immersive state (refer to FIG. 4), the lock member B is moved to the protruding position by the link member 12 and the steering lock is performed. is there.

  As shown in FIG. 3, the cover member 7 is configured such that the front end of the operation member 10 is inserted therein, and a flange portion 7 a is formed at the lower peripheral edge, and is separate from the operation member 10. Has been. The cover member 7 and the distal end of the operation member 10 are not fixed by adhesion or welding, and only cover the upper end (that is, the outer surface) of the operation member 10. Therefore, even if the cover member 7 is pulled upward from the operation member 7 in the immersive state as shown in FIG. 4, only the cover member 7 moves upward and the operation member 7 does not follow as shown in FIG. It has become.

  That is, the operating member 10 moves from the protruding state to the immersive state following the pressing of the cover member 7, but the operating member 10 is in the direction from the immersive state to the protruding state of the operating member 10. 7 is configured not to follow 7. As a result, it is possible to prevent the lock of the lock bar B from being illegally released by forcing the operating member 10 into the protruding state, and the antitheft effect can be further improved. When the cover member 7 and the operation member 10 are in the projecting state, the flange portion 7a of the cover member 7 comes into contact with the stepped portion 9aa of the lid body 9a, and further raising operation is restricted.

  As shown in FIGS. 8 and 9, the motor 8 has an output shaft 8a coupled to a cam member 15. The cam member 15 has a cam portion 15a and a concave portion 17b of the locking member 17. It is possible to rotate within. The locking member 17 is slidable in the left-right direction in FIG. 9 on the sliding surface 9 ab of the main body 9, and is urged toward the operation member 10 by the spring 16. The motor 8, the locking member 17 and the cam member 15 constitute an electric release means of the present invention.

  However, when the cam portion 15a comes into contact with the operation member side wall surface 17ba of the recess portion 17b as the cam member 15a rotates, the movement of the locking member 17 in the right direction in FIG. When 15a abuts against the spring side wall surface 17bb of the recess 17b, the locking member 17 can be moved rightward in the figure against the urging force of the spring 16. When the cam portion 15a is in the state shown in FIG. 9, the locking member 17 is positioned at the left end of the drawing and moves in the same direction against the urging force of the spring 16 when a pressing force is applied to the right side. It has come to be able to do.

  Further, the locking member 17 is formed with a locking portion 17 a protruding toward the operation member 10, and engages with the locked portion 10 a formed by protruding from the operation member 10 to engage the operation member 10. It is configured to be able to stop. That is, when the operation member 10 is changed from the protruding state to the immersive state in a state where the cam portion 15a of the cam member 15 is not in contact with the operation member side wall surface 17ba and the spring side wall surface 17bb in the concave portion 17b (state of FIG. 9). The locked portion 10a presses the upper surface of the locking portion 17a and moves the locking member 17 against the urging force of the spring 16, and then the locked portion 10a reaches the lower surface of the locking portion 17a. Then, the locking member 7 returns to the original position by the urging force of the spring 16, and the locked portion 10a comes into contact with and locks to the lower surface of the locking portion 17a (see FIG. 10).

  On the other hand, when the driver carrying the transmission means 2 approaches, the determination means 4 determines that the reception means 3 has received a legitimate ID code, and the access button 5 is operated. The member 15 is rotated, and the cam portion 15a of the cam member 15 is brought into contact with the spring side wall surface 17bb as shown in FIG. As a result, the locking member 17 moves against the biasing force of the spring 16 and the locking between the locking portion 17a and the locked portion 10a is released, so that the operation member 10 is moved by the biasing force of the spring 11. Ascends and protrudes from the immersive state.

  Thus, when the immersive operation member 10 is in the protruding state, the lock bar B is interlocked via the link member 12 and moves from the protruding position engaged with the steering to the retracted position, so that the steering lock is released. It becomes. Therefore, the steering lock can be released by electric drive by the motor 8 and can be easily applied to a vehicle equipped with a so-called smart entry system as in this embodiment.

  After the steering lock is released (after the start button 6 is operated, etc.), the cam member 15 is rotated by driving the motor 8, and the cam portion 15a is placed on the operation member side wall surface 17ba in the recess 17b as shown in FIG. It is in a contact or close state. As a result, the movement of the locking member 17 toward the spring 16 is restricted, so that even if the cover member 7 is pressed, the locked portion 10a does not interfere with the locking portion 17a and the operating member 10 does not descend. It has become. Therefore, it can be avoided that the driver accidentally presses the operation member 10, and safety can be improved.

  Further, as shown in FIGS. 8 and 10, a magnet M1 is formed on a part of the operation member 10, and a magnet M2 is formed on a part of the cam member 15 (on the cam portion 15a side). On the other hand, a sensor S1 for detecting the magnetic force of the magnet M1 is disposed at a position facing the magnet M1 in the lid body 9a of the main body 9, and the vicinity of the operation member side wall surface 17ba and the spring side wall surface 17bb of the recess 17b. Sensors S2 and S3 for detecting the magnetic force of the magnet M2 are disposed at positions facing the vicinity. The sensors S1 to S3 are preferably made of a Hall IC or the like, but may be other sensors that can detect a magnetic force.

  Since the sensors S1 to S3 can grasp whether the operation member 10 is in the protruding state or the immersive state, and in what direction the cam member 15 is oriented, based on the detection of the sensor, The occurrence of a malfunction (such as a malfunction of the lock bar B) can be ascertained, and in this case, the malfunction can be recognized by the driver by, for example, a warning by a warning light or the like.

  According to the steering lock device, the steering lock is performed by manually operating the operation member 10, and the motor is driven by the electric release unit on the condition that it is determined that the proper ID code is received, and the steering lock is released. Therefore, the operability can be improved by eliminating the need for an operation with a mechanical key or the like. Further, the operating member 10 moves from the protruding state to the immersive state following the pressing of the cover member 7, and the operating member 10 is moved in the direction from the immersive state to the protruding state of the operating member 10. Therefore, the antitheft effect can be further improved. Furthermore, since the operation member 10 and the lock bar B are interlocked via the link member 12, the manual operation of the operation member 10 at the time of steering lock can be performed more smoothly and reliably than the interlock operation by the cam or the like. it can.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, instead of the electric release means including the motor 8, the locking member 17, and the cam member 15, the determination means 4 receives a regular ID code. On the condition that it is determined that the operation has been performed, the motor 8 may be driven so that the operation member in the immersive state is in the protruding state and the lock bar B is unlocked from the steering. Further, instead of the link member 12, the operation member 10 and the lock bar B may be connected and interlocked to each other (for example, interlocking by a cam).

  A steering lock device that locks the steering by manual operation and releases the steering lock on the condition that the received ID code is valid, and the operation member follows the pressing of the cover member. If the steering lock device moves from the protruding state to the immersive state and the operating member does not follow the cover member in the direction from the immersive state to the protruding state of the operating member, a different appearance shape or other function is added. It can also be applied to what has been done.
