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, in the above-described conventional steering lock device, since the pressing operation from the protruding state to the immersive state by the push button can be performed at any timing, there is a problem that the steering lock is performed even by an erroneous operation. . In other words, there is almost no need to lock the steering while the vehicle engine is being driven, but in such a case, if the push button is accidentally pressed, the steering lock is inadvertently performed. There was a problem that.

  The present invention has been made in view of such circumstances, and can improve the operability by eliminating the need for an operation with a mechanical key or the like, and can avoid an inadvertent steering lock due to a driver's erroneous operation or the like. The object is to provide a steering lock device.

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 authentic, and the pushing state changes from the protruding state to the immersive state, and the lock bar is locked to the steering of the vehicle to lock the steering. On the condition that the operation member and the determination means have received a legitimate ID code, the motor is driven, the operation member in the immersive state is brought into a protruding state, and the lock bar is unlocked from the steering. A steering lock device having an electric release means capable of releasing the steering lock, wherein the electric release means is in contact with or separated from the operation member. And a cam member that rotates by driving the motor to operate the locking member or restrict the operation of the locking member. A release state in which the steering lock can be released with the operation member in the protruding state, an allowable state in which the pressing operation of the operation member from the protruding state to the immersive state is allowed, and even if the operation member in the protruding state is pressed A restricting state for restricting the operation member from being immersed is selectively performed.

  According to a second aspect of the present invention, in the steering lock device according to the first aspect, the cam member rotates to an angle at which the restricted state is achieved by starting the engine in the vehicle, and the permitted state is achieved by stopping the engine. It is controlled to rotate to a certain angle.

  According to a third aspect of the present invention, in the steering lock device according to the first or second aspect, the first detecting means for detecting the protruding state and the immersed state of the operation member and the rotation angle of the cam member are detected. 2 detection means.

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, depending on the rotation angle of the cam member, the retracted state where the operation member in the immersive state is in the protruding state and the steering lock can be released, the allowable state allowing the pressing operation from the protruding state of the operating member to the immersive state, and the protruding state Even if the operation member is pressed, a restriction state for restricting the operation member from being immersed is selectively made, so that an inadvertent steering lock due to a driver's erroneous operation or the like can be avoided. .

  According to the second aspect of the present invention, the cam member is controlled to rotate to an angle at which the restricted state is achieved by starting the engine in the vehicle and to an angle at which the permitted state is achieved by stopping the engine. During the driving, the pressing operation of the operation member can be restricted, and the safety can be further improved.

  According to the invention of claim 3, since the relationship between the state of the operating member and the rotation angle of the cam member can be grasped by the first detecting means and the second detecting means, a reliable steering lock or its releasing operation can be performed. This can be performed, and safety can be further improved.

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. Transmitting means 2 for transmitting the ID code unique to the vehicle and 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 a regular one 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, the operating member 7 is pressed by the pressing of the cover member 7 and is lowered 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. Further, the cover member 7 may be integrated with or separate from the operation member 7, or the cover member 7 may be abolished with the end of the operation member 7 as a button shape.

  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. 5, 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 FIGS. 7 and 8, the motor 8 has an output shaft 8a connected to a cam member 15. The cam member 15 has a cam portion 15a and a recess 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. 8 on the sliding surface 9ab of the main body 9, and is urged toward the operation member 10 side by the spring 16 and is moved toward the operation member 10 side. A protruding locking portion 17a is formed, and is configured to be able to lock the operating member 10 by contacting the locked portion 10a formed by protruding from the operating member 10. The motor 8, the locking member 17 and the cam member 15 constitute an electric release means of the present invention.

  Here, according to the steering lock device according to the present embodiment, depending on the rotation angle of the cam member 15 (the direction of the cam portion 15a), a release state in which the steering lock can be released with the operation member 10 in the immersive state protruding. An allowable state in which the pressing operation of the operation member 10 from the protruding state to the immersive state is permitted and a restriction state in which the protruding operation member 10 is prevented from being in the immersive state are selectively configured. .

  Specifically, when 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 recess 17b (allowable state shown in FIG. 8), the operation member 10 is immersed from the protruding state. In the state, the locked portion 10 a presses the upper surface of the locking portion 17 a and moves the locking member 17 against the urging force of the spring 16. Thereafter, when the locked portion 10a reaches the lower surface of the locking portion 17a, the locking member 7 returns to the original position by the biasing force of the spring 16, and the locked portion 10a comes into contact with the lower surface of the locking portion 17a. And locked (see FIG. 7).

  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 released state shown in FIG. 11 is obtained by rotating the member 15, and the cam portion 15a of the cam member 15 is brought into contact with the spring side wall surface 17bb. 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.

  Further, the cam member 15 is controlled to rotate to an angle at which the restricted state shown in FIG. In this restricted state, the cam portion 15a is in contact with or close to the operation member side wall surface 17ba in the concave portion 17b, and the movement of the locking member 17 toward the spring 16 is restricted. Even when the operating member 10 is pressed by pressing the locked portion 10a, the locked portion 10a contacts the locking portion 17a so that the operating member 10 does not descend.

  Accordingly, it is possible to prevent the driver from accidentally pressing the operation member 10 during traveling of the vehicle, and to avoid inadvertent steering lock due to an erroneous operation. The cam member 15 is controlled to rotate to the permissible state shown in FIG. 8 by stopping the engine E in the vehicle, and the pressing operation of the operation member 10 is permitted and the steering lock is enabled.

  Further, as shown in FIGS. 7 and 9, 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 (first detection means) 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 operation member side wall surface 17ba of the recess 17b. Sensors S2 and S3 (second detection means) for detecting the magnetic force of the magnet M2 are disposed at positions near the vicinity and the vicinity of the spring side wall surface 17bb. 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.

  However, the sensor S1 can detect the protruding state and the immersed state of the operation member 10, and the sensors S2 and S3 can detect the rotation angle of the cam member 15 (specifically, the released state, the allowable state, and the restricted state). Corresponding rotation angle) can be detected. Since these sensors S1 to S3 can grasp the relationship between the state of the operation member 10 and the rotation angle of the cam member 15 (particularly the direction of the cam portion 15a), it is possible to perform a reliable steering lock or its release operation. It is possible to improve safety.

  That is, when the operation member 10 is in the protruding state and in the allowable state, the sensor S1 detects the magnetic force of the magnet M1, and neither of the sensors S2 and S3 detects the magnetic force of the magnet M2. When the operation member 10 is in the immersive state and in the restricted state, the sensor S1 does not detect the magnetic force of the magnet M1, and only the sensor S2 of the second detection means detects the magnetic force of the magnet M2. Further, when the operation member 10 is in the protruding state after being released, the sensor S1 detects the magnetic force of the magnet M1, and only the sensor S3 of the second detection means detects the magnetic force of the magnet M2. As a result, if a sensor different from the above is detected, it can be determined that some malfunction (such as malfunction of the lock bar B) has occurred, and the malfunction can be recognized by the driver, for example, by 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 cam member 15 is controlled to rotate to an angle at which the restricted state is achieved by starting the engine in the vehicle and to an angle at which the permitted state is achieved by stopping the engine. 10 pressing operations can be restricted, and safety can be further improved.

  Furthermore, since the release state, the permissible state, and the restriction state are selectively made according to the rotation angle of the cam member 15, the device configuration can be simplified and a reliable steering lock or its release operation can be performed. Since the relationship between the state of the operation member 10 and the rotation angle of the cam member 15 can be grasped by the first detection means (sensor S1) and the second detection means (sensors S2 and S3), reliable steering lock Or the cancellation | release operation | movement can be performed and safety | security can be improved more.

  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).

This is a steering lock device that locks the steering by manual operation and releases the steering lock on condition that the received ID code is valid, and projects the immersive operation member according to the rotation angle of the cam member. As a state, a release state in which the steering lock can be released, an allowable state in which the pressing operation from the protruding state of the operation member to the immersive state is permitted, and the operation member is in the immersive state even if the operating member in the protruding state is pressed. As long as the steering lock device is selectively controlled with a restricted state for restricting the movement, it can also be applied to devices with different external shapes or with other functions added.
