Description

  The present invention relates to an ignition switch device that permits starting of an engine on the condition that an ID code from a transmission means is determined to be a regular one registered in advance.

  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 motorcycle, 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.

  On the other hand, ordinary motorcycles have various lock mechanisms such as a steering lock mechanism that locks the handlebar, a tank cap lock mechanism that restricts the opening of the tank cap, and a seat lock mechanism that restricts the opening of the seat for seating. The auxiliary keys (mechanical keys) for releasing these locks have been conventionally attached to the transmission means. Then, the lock mechanism is unlocked by removing the mechanical key from the transmitting means and rotating the mechanical key while inserting the mechanical key through the rotor of a key cylinder formed in an arbitrary lock mechanism. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the above conventional ignition switch device, in order to unlock the various lock mechanisms provided in the vehicle, it is necessary to remove the auxiliary mechanical key from the transmission means and to insert the mechanical key into the key cylinder rotor in the lock mechanism. Therefore, there is a problem that the operation is troublesome. In other words, with the smart entry system, when the engine is started, it is only necessary for the driver to carry the transmitter in a pocket of clothes, etc., but in the conventional ignition switch device described above, any lock mechanism can be unlocked. For the operation, it was necessary to take out the transmission means from a pocket and remove the mechanical key from there.

  It is to be noted that the receiving means receives the ID code transmitted from the transmitting means, and automatically unlocks the various locking mechanisms as described above on the condition that it is determined that the ID code is registered in advance. However, in this case, a motor unit for unlocking each lock mechanism is required, which increases the manufacturing cost.

  In view of the above, the present applicant puts the mechanical key from the rotor on the condition that the mechanical key is normally inserted into the rotor and the ID code received by the receiving means is determined to be genuine by the determining means. I came to study the ignition switch device that can be extracted. However, if the mechanical key is not rotated properly and the rotor is positioned between the OFF position and the steering lock position, or if you forget to rotate the steering lock position when parking, the steering lock is normal. There was a risk of vehicle theft.

  The present invention has been made in view of such circumstances, and can improve the operability for unlocking various lock mechanisms provided in the vehicle, can suppress the manufacturing cost, and can control the steering. An object of the present invention is to provide an ignition switch device capable of securely locking and preventing theft of a vehicle.

The invention according to claim 1 is a transmission means that can be carried by the driver and can transmit a vehicle-specific ID code, a reception means that can receive an ID code transmitted from the transmission means, and a reception means that receives the ID code. In an ignition switch device comprising: a determination means for determining whether or not a registered ID code is an authorized one registered in advance, and permitting engine start on condition that the ID code is authorized A mechanical key for releasing various lock mechanisms included in the can be inserted, and an on position for starting the engine by rotating the inserted mechanical key, an off position for stopping the engine, and a steering lock for locking the handlebar together may be rotated between the positions, is possible removal of the mechanical key when in the oFF position, oN position And a rotor extraction of the mechanical key is restricted when in the steering lock position, the detectable means of detection the rotation position of the rotor, and a regulating means for locking the rotation of the rotor, the mechanical key at all times The mechanical key is removed from the rotor when necessary, and the ID code received by the receiving means is determined to be genuine by the determining means. As a condition, it is possible to remove the mechanical key from the rotor by releasing the lock by the restricting means and allowing the rotor to turn to the off position, and the receiving means does not receive a regular ID code. The position of the rotor is detected by the detecting means.

  According to a second aspect of the present invention, in the ignition switch device according to the first aspect, a terminal block that rotates in conjunction with the rotor and can form a predetermined circuit for starting the engine when the rotor is in the on position. The detection means includes a magnetic generation means that is formed at a predetermined position of the terminal block and can generate magnetism, and a magnetic detection means that detects magnetism from the magnetic generation means. The position of the rotor can be detected by magnetic detection by means.

  According to a third aspect of the present invention, in the ignition switch device according to the first or second aspect, the receiving means does not receive a proper ID code, and the rotor is in a steering lock position by the detecting means. When not detected, a predetermined warning is issued.

  According to the first aspect of the invention, on the condition that the ID code received by the receiving means is determined to be genuine by the determining means, the lock by the restricting means is released and the mechanical key is removed from the rotor. Since this is possible, there is no need to take out the portable transmission means for releasing the locks of various lock mechanisms provided in the vehicle as in the prior art.

  Therefore, the operability can be improved, and a motor unit or the like for unlocking each lock mechanism is not necessary, so that the manufacturing cost can be suppressed. At the same time, when the receiving means does not receive the proper ID code, the position of the rotor is detected by the detecting means, so that the steering lock can be surely performed to prevent the vehicle from being stolen.

  According to the invention of claim 2, since the position of the rotor can be detected by the magnetic detection by the magnetic detection means, the position of the rotor can be detected without contact. Therefore, compared to the contact type, it is possible to avoid the occurrence of frictional resistance or the like when the rotor is rotated, maintain operability, and reliably detect the position of the rotor. Can do.

  According to the invention of claim 3, when the receiving means does not receive the regular ID code and the detecting means does not detect that the rotor is in the steering lock position, the predetermined warning is given. It is possible to prevent the driver carrying the transmission means from leaving the vehicle while forgetting.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The ignition switch device according to this embodiment is for controlling engine start and stop in a two-wheeled vehicle. As shown in FIGS. 1 and 2, a cylinder body 6 constituting a main body of the ignition switch device, and a mechanical key K As shown in FIG. 5, the transmission means 1 that can be carried by the driver and can transmit a vehicle-specific ID code, and the transmission means 1 that is disposed on the vehicle side are provided. Receiving means 2 capable of receiving the ID code, and determining means 3 for determining whether or not the ID code received by the receiving means 2 is a registered regular one.

  The transmission means 1 is capable of transmitting an ID code at all times by radio waves or the like. When the driver carrying the transmission means 1 approaches the vehicle, the vehicle-side reception means 2 can receive the ID code. ing. The judging means 3 compares the ID code registered in advance with the ID code received by the receiving means 2, and judges that the legitimate ID code has been received if they match. The engine E is allowed to start on condition that the access switch 4 to be described in detail is turned on and the vehicle is turned on.

  Incidentally, after the judging means 3 judges that the receiving means 2 has received the regular ID code and the access switch 4 is turned on, the mechanical key K is turned to the on position, whereby the ignition switch 5 is turned on to a predetermined circuit. And the engine E of the vehicle can be started. Therefore, when the driver approaches the vehicle and the receiving means 2 receives the proper ID code, the access switch 4 is turned on and the mechanical key K is rotated to turn on the power and start the engine. And operability can be improved.

  On the other hand, as shown in FIGS. 1 to 4, the cylinder body 6 has a rotor 7 that can be rotated by inserting a mechanical key K, an actuator 8 that can rotate in conjunction with the rotor 7, and a protruding state. Thus, a lock bar R that can be engaged with a rotation shaft of a handle bar (not shown) to lock the handle bar, and a terminal block 4 that constitutes the ignition switch 5 are provided inside.

  The mechanical key K can be inserted into the rotor 7 to rotate the rotor 7, and the various lock mechanisms (a tank cap lock mechanism that restricts the opening of the tank cap provided in the vehicle, or the opening of the seat) are provided in the vehicle. In order to release the lock of the seat lock mechanism), it can be inserted through the rotor of each lock mechanism. The gripping portion of the mechanical key K is shaped like a knob with a flat tip, and is easy to rotate and press.

  The rotor 7 is configured such that a plurality of tumblers are arranged at regular intervals in the axial direction, and can be rotated around the axis only when a matching mechanical key K is inserted, and the inserted mechanical key K is operated to rotate. Thus, the engine E is configured to be rotated between an on position where the engine E is started, an off position where the engine E is stopped, and a steering lock position where the handlebar is locked.

  Further, when the rotor 7 is in the off position, the internal tumbler is allowed to move and the mechanical key K can be inserted and removed, whereas when the rotor 7 is in the on position and the steering lock position, the tumbler is moved. The mechanical key K is restricted from being removed. For example, when the mechanical key K is rotated from the off position to the right, the on position is set, and when the mechanical key K is rotated from the off position to the left, the steering lock position is set.

  Thus, when the mechanical key K is rotated from the off position to the steering lock position and the rotor 7 is rotated in a predetermined direction, the operating element 8 rotates in the same direction, and the cam 8 is integrated with the operating element 8. Thus, the handle bar can be locked by protruding the lock bar R. On the other hand, when the mechanical key K is rotated from the off position to the on position and the rotor 7 is rotated in a predetermined direction, the terminal block 9 rotates in conjunction with the actuator 8 and is formed on the terminal block 9. A predetermined circuit is formed between the movable contact 9a and a fixed contact (not shown), and the engine E of the motorcycle can be started.

  A substrate 10 on which a circuit is formed is disposed below the terminal block 9, and an access switch 4 including a tact switch is disposed on the substrate 10. The access switch 4 is disposed below the lower end of the operating element 8. When the mechanical key K is pressed to move the operating element 8 downward, the lower end of the operating element 8 turns on the access switch 4. The vehicle is turned on so that various electrical components of the vehicle can be operated. That is, when the receiving means 2 receives the regular ID code and presses the mechanical key K, the access switch 4 is turned on, and the engine start operation by the ignition switch 5 is allowed.

  Further, as shown in FIGS. 3 and 4, a magnet 14 (magnet generation means) capable of generating magnetism is formed at a predetermined position on the side surface of the terminal block 9 and the magnetism of the magnet 14 is detected. A Hall IC element 13 (magnetic detection means) is formed on the substrate 10. More specifically, the extending portion 15 is extended upward from the substrate 10, and the Hall IC element 13 is formed at the protruding end thereof, so that the Hall IC element 13 is opposed to the side surface of the terminal block 9.

  At least two Hall IC elements 13 are formed on the substrate 10, and when the rotor 7 is in the off position or the steering lock position, either one faces the magnet 14 and can detect the magnetism. Has been. Thereby, the rotation position (off position and steering lock position) of the rotor 7 can be detected based on the magnetic detection by the Hall IC element 13. The magnet 14 and the Hall IC element 13 constitute a detection means 16 (see FIG. 5) of the present invention.

  According to the above configuration, since it is possible to detect that the rotor 7 is in the off position or the steering lock position by detecting magnetism by the Hall IC element, the position of the rotor 7 can be detected without contact. Therefore, compared to the contact type, it is possible to avoid the occurrence of frictional resistance or the like when the rotor 7 is rotated, maintain operability, and reliably detect the position of the rotor 7. Can be made.

  As shown in FIG. 5, the detection unit 15 is connected to the determination unit 3, and when the reception unit 2 does not receive a regular ID code, the detection unit 15 rotates the rotor 7 (off position and steering lock). Position) can be detected. Further, when the warning means 17 is connected to the determination means 3 and the reception means 2 does not receive a proper ID code and the detection means 15 does not detect the steering lock position, the warning means 17 gives a predetermined warning. Is configured to perform.

  Accordingly, it is possible to prevent the driver carrying the transmission means 1 from leaving the vehicle without turning the mechanical key K to the steering lock position during parking or the like and forgetting the steering lock. it can. The warning means 17 may be any means for notifying the driver that the steering lock is forgotten, and may be, for example, a speaker or a warning light that can emit a warning sound or sound.

  On the other hand, the cylinder body 6 is provided with restricting means 12 for locking the rotation of the rotor 7 and a solenoid 11 for releasing the lock of the rotor 7 by the restricting means 12. As shown in FIG. 4, the restricting means 12 is swingable about an axis L, its base end 12 b is connected to the plunger 11 a of the solenoid 11, and the tip 12 a is a predetermined position of the actuator 8. It is comprised so that it can latch with the notch 8b formed in this. The restricting means 12 is urged by a torsion spring (not shown) in a direction in which the tip 12a is pressed toward the notch 8b.

  The notch 8b formed in the operating element 8 is formed at a position corresponding to the on position and the steering lock position of the rotor 7, and is locked to the on position or the steering lock position when the tip 12a of the restricting means 12 is locked. The rotation of a certain rotor 7 can be restricted and locked. However, as described above, when the rotor 7 is in the on position and the steering lock position, the movement of the tumbler is restricted, so that the mechanical key K is not extracted from the rotor 7.

  When the determination unit 3 determines that the ID code received by the reception unit 2 is genuine, the solenoid 11 attracts the plunger 11a by energization and moves it downward in the figure. As a result, the base end 12b of the restricting means 12 is also pushed downward, the restricting means 12 swings about the axis L, and the distal end 12a is separated from the notch 8b, so that the rotor 7 is unlocked. In this state, if the mechanical key K is rotated to rotate the rotor 7 to the off position, the mechanical key K can be removed from the rotor 7.

  That is, on the condition that the determination unit 3 determines that the ID code received by the reception unit 2 is genuine, the lock by the restriction unit 12 can be released and the mechanical key K can be removed from the rotor 7. Therefore, in the engine start state or the steering lock state, removal of the mechanical key K from the rotor 7 is restricted, and when necessary (for example, a tank cap lock mechanism for restricting the opening of the tank cap provided in the vehicle, (When releasing the lock of the seat lock mechanism that restricts the opening of the seat), the mechanical key K can be removed and inserted into the rotor (not shown) of each lock mechanism so that the lock can be released. It has become.

  Accordingly, since it is not necessary to take out the transmitter 1 carried in order to unlock the various locking mechanisms provided in the vehicle as in the prior art, the operability can be improved and the lock mechanism can be unlocked in each locking mechanism. No motor unit or the like is required, and the manufacturing cost can be reduced. Further, since the mechanical key K is not extracted unless the proper ID code is received by the receiving means 2, it is possible to prevent an unauthorized key operation or theft of the mechanical key K by a third party or the like.

  Furthermore, the mechanical key K can be removed from the rotor 7 only when the receiving means 2 receives a legitimate ID code and the rotor 7 is in the off position. For example, the tank cap lock mechanism is unlocked. When removing the mechanical key K, the rotor 7 is set to the off position and the engine is stopped, so that safety during refueling can be ensured.

  Further, since the rotor 7 is in the on position when the vehicle is running, the mechanical key K is not allowed to be removed even if the receiving means 2 receives the regular ID code. It is possible to avoid pulling out from 7. The mechanical key K can be easily applied to a lock mechanism in an existing two-wheeled vehicle because it can unlock the tank cap lock mechanism that restricts the opening of the tank cap provided in the vehicle or the seat lock mechanism that restricts the opening of the seat. can do.

  Furthermore, according to the present embodiment, when the receiving means 2 does not receive a regular ID code, the detecting means 16 detects that the rotor 7 is in the off position or the steering lock position, so that the steering lock is performed reliably. Accordingly, it is possible to prevent the vehicle from being stolen. That is, the mechanical key K is not rotated well, and the rotor 7 is positioned between the off position and the steering lock position, or the forgotten operation to rotate to the steering lock position when parking is performed. Since the detection means 16 can detect that the driver carrying the transmission means 1 tries to move away from the vehicle, it is possible to prevent the vehicle from being stolen.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the detection means may have another configuration, for example, a part of the terminal block 9 is magnetized to generate magnetism. Alternatively, instead of the Hall IC element, other magnetism detection means that can detect the magnetism of the magnetism generating means formed on the terminal block 9 and detect the off position or the steering lock position of the rotor 7 may be used.

  Further, the restricting means may have another configuration, for example, it may be configured to lock the rotation of the rotor by directly engaging with the rotor. Further, the rotor in the present embodiment is rotatable between the on position, the off position, and the steering lock position. In addition to this, a seat lock release position is provided, and the rotation of the mechanical key K rotates the seat. The seat lock mechanism that restricts the opening may be unlocked. In addition, an access switch for turning on the power of the vehicle may be provided separately, and the access switch 4 including the tact switch of this embodiment may be eliminated.

The mechanical key is always inserted into the rotor, and the mechanical key can be removed from the rotor when necessary. The condition is that the determination means determines that the ID code received by the receiving means is authentic. The mechanical key can be removed from the rotor by releasing the lock by the restricting means and allowing the rotor to turn to the off position, and when the receiving means does not receive a regular ID code, the detecting means As long as the ignition switch device detects that the rotor is in the off position or the steering lock position, it can also be applied to ones with different appearance shapes or other functions added.
