It can be arranged at a position, and the degree of freedom in layout can be improved. Further, since the key cylinder can be disposed at a position separated from the starter body, the anti-theft effect can be further improved.

  According to the second aspect of the present invention, since the mechanical key is restricted from being extracted while the rotor is rotated, after the battery running out of the transmitting means is resolved and the ID code can be transmitted to the receiving means. Forgetting to return the rotor to the initial position, it can be avoided that the lock by the lock means continues to be released.

  According to the invention of claim 3, the arm member connected to the tip of the wire on the main body side of the starting device and operating in accordance with the rotation of the rotor to release the lock by the locking means is provided, and the arm member is covered. Since the cover is provided, it is possible to prevent a third party for the purpose of theft or mischief from operating the arm member and illegally releasing the lock by the lock means.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The engine starting device according to the present embodiment constitutes an ignition switch (keyless ignition switch) of a motorcycle in a so-called smart entry system. As shown in FIG. 1, the starting device body 1, the key cylinder 2, and the transmission means 3, receiving means 4, authentication means 5, operation knob 6, solenoid 7, locking means 12, arm member 8, and cover 9.

  The transmission means 3 is a device that can be carried by the driver and transmits a vehicle-specific ID code wirelessly, for example, by radio waves. The receiving means 4 is disposed on the vehicle side and receives an ID code from the transmitting means 3, and includes an antenna or the like for receiving radio waves including the ID code. The transmission means 3 continuously transmits an ID code at a predetermined interval by a power source such as a battery. When the driver approaches the motorcycle while carrying the transmission means 3, the antenna of the reception means 4 is set to the ID code. Can be received.

  The authentication means 5 is provided on the vehicle side and is used to authenticate whether the ID code received by the receiving means 4 is unique to the vehicle (set regular ID code). As a result, if it is determined that the ID code is genuine, the solenoid 7 described later can be energized. If the receiving means 4 does not receive anything or it is determined that the received ID code is not authentic, the solenoid 7 is not energized.

  On the other hand, the starter main body 1 constitutes the casing of the present apparatus including the operation knob 6, the solenoid 7, the lock means 12, the arm member 8, the cover 9, and the like. Further, in the starter body 1, there are disposed a rotating shaft 10 that rotates in conjunction with the operation knob 6, and an ignition switch 11 that forms a predetermined circuit as the rotating shaft 10 rotates. The ignition switch 11 can be turned on or off via the turning shaft 10 by turning the operation knob 6.

  The operation knob 6 is composed of an integrally molded product having a shape that can be picked by the driver at the top, and can be rotated between an on position and an off position, as shown in FIG. In this embodiment, in addition to the on position and the off position, a lock position for projecting the lock bar R is formed, and the vehicle handle bar (not shown) can be locked at the lock position. ing.

  When the operation knob 6 is turned from the off position to the on position, the ignition switch 11 is operated via the turning shaft 10 on the condition that the receiving means 4 has received the proper ID code from the sending means 3. The engine of the vehicle can be started, and when the operation knob 6 is turned from the on position to the off position, the engine can be stopped. That is, an ignition key comprising a conventional mechanical key is not required, and the engine can be started and stopped by rotating the operation knob 6.

  The solenoid 7 is electrically connected to the authentication means 5 as described above, and can energize an internal coil (not shown) based on the authentication result. As shown in FIG. A possible plunger 7a is provided. When it is determined by the authenticating means 5 that the receiving means 4 has received the regular ID code, the internal coil is energized and the plunger 7a can be immersed downward in the figure.

  The lock means 12 is swingable about the swing shaft L1. One end 12a of the lock means 12 is engaged with the plunger 7a, and the other end 12b is engaged with a groove portion 10a formed on the rotating shaft 10. It can be stopped. Therefore, when the receiving means 4 does not receive the proper ID code, the other end 12b of the locking means 12 is locked with the groove portion 10a of the rotating shaft 10, so that the rotation of the operation knob 6 is locked. Will be regulated.

  On the other hand, when the receiving means 4 receives the regular ID code, the plunger 7a moves downward and is immersed, and the locking means 12 is swung around the swinging shaft L1, so that the two-dot chain line in FIG. In addition, the other end 12b is separated from the groove 10a, and the engagement with the rotating shaft 10 is released. Thereby, on condition that the receiving means 4 has received the ID code (regular ID code) from the sending means 3, the lock can be released and the operation knob 6 can be allowed to rotate.

  The arm member 8 is formed with a connecting portion 13 that can be connected to the wire W at the base end (lower end in the figure), and a long member whose distal end 8a is located above the one end 12a of the locking means 12. It consists of When the wire W is pulled, the arm member 8 can be moved downward against the urging force of the spring S1, and the tip 8a has a locking means as shown by a two-dot chain line in FIG. The one end 12a of 12 is pressed, the other end 12b is separated from the groove 10a, and the locking to the rotating shaft 10 can be released.

  That is, even if the receiving unit 4 does not receive a regular ID code from the transmitting unit 3 due to the battery running out of the transmitting unit 3, the arm member is pulled by pulling the wire W by operating an auxiliary mechanical key K described later. If 8 is moved downward, similarly to the energization of the solenoid 7, the lock means 12 is swung around the rocking shaft L 1 to release the lock, and the operation knob 6 can be rotated. It can be done. Therefore, it can be avoided that the engine cannot be started due to the malfunction of the transmission means 3 despite the owner of the vehicle.

  Further, the starter body 1 is provided with a cover 9 for covering the arm member 8, and a third party for the purpose of theft or mischief inserts a hand from outside to operate the arm member 8, Unlocking the lock by the lock unit 12 can be avoided. Therefore, the anti-theft effect can be improved.

  Here, in this embodiment, as shown in FIGS. 5 and 6, the connection portion 13 is formed with a notch 13 a, and the notch 13 a has a drum-like shape formed at one end of the wire W. The locking member Wa is configured to be locked. The operation of the wire W for manual unlocking is configured to be performed by the key cylinder 2.

  The key cylinder 2 is separated from the starter main body 1 and is connected to the starter main body 1 through a wire W, and an auxiliary mechanical key K is inserted as shown in FIG. A rotor 15 that can rotate around an axis and an operation plate 17 that rotates in conjunction with the rotor 15 are disposed, and these are housed in a cylinder body 16. In the figure, reference numerals S2 and S3 denote a torsion spring connected to the operation plate 17 and a coil spring formed at the lower end of the rotor 15.

  The rotor 15 is movable downward against the urging force of the coil spring S3, and includes a plurality of tumblers (not shown). When the auxiliary mechanical key K is inserted from the key hole 2a, the rotor 15 is aligned. The rotation about the axis is made possible. As shown in FIG. 8, a part of the operation plate 17 connected to the lower end of the rotor 15 protrudes to the outside of the cylinder body 16, and the protrusion constitutes a connection portion 14.

  The connection portion 14 is formed with a notch 14a, and a drum-shaped locking member Wb formed at the other end of the wire W is locked to the notch 14a. As a result, the connecting portion 14 and the connecting portion 13 of the arm member 8 on the starter body 1 side are connected by the wire W, and when the turning operation is performed while inserting the auxiliary mechanical key K from the key hole 2a. Then, the operation plate 17 is rotated together with the rotor 15, and the connecting portion 14 is in a state of a two-dot chain line in FIG. 8 to pull the wire W.

  When the wire W is pulled, the arm member 8 can be moved downward via the connecting portion 13, and as described above, the lock means 12 is swung around the swing axis L1 to release the lock. Therefore, the operation knob 6 can be turned. Therefore, even if the receiving means 4 does not receive the proper ID code from the sending means 3 due to the battery running out of the sending means 3, if the manual operation with the auxiliary mechanical key K is performed, the lock by the locking means 12 is released. Then, the engine can be started and the handlebar can be unlocked.

  Further, the key cylinder 2 is configured to restrict the withdrawal of the auxiliary mechanical key K in a state where the rotor 15 is rotated (a state where the lock by the lock means 12 is released by manual operation). Specifically, in the initial position (state before operation), the rotor 15 can be inserted and removed with the auxiliary mechanical key K, and the auxiliary mechanical key K is inserted and rotated. Later, the auxiliary mechanical key K is locked so that it cannot be removed. As a result, after the battery of the transmission means 3 is eliminated and the ID code can be transmitted to the reception means 4, the rotor 15 is forgotten to return to the initial position, and the lock by the lock means 12 continues to be released. Can be avoided.

  On the other hand, if the auxiliary mechanical key K is rotated to the initial position, it can be removed from the rotor 15, and the wire W is returned to its original state and the pulling force on the arm member 8 is released. The arm member 8 is lifted by the urging force of the spring S1, and its tip 8a is separated from the one end 12a of the locking means 12 and is in the state of the solid line in FIG. 4 (ie, the state before unlocking by the auxiliary mechanical key K). The

  Then, as shown in FIG. 9, the starter body 1 and the key cylinder 2 as described above are separated from each other in the two-wheeled vehicle (for example, the starter body 1 is located below the handlebar, and the key cylinder 2 is the meter panel. And the like in a separate cover adjacent to each other). In the case of the figure, the operation knob 6 of the starter main body 1 is arranged facing the outside and can be operated by the driver, and the key cylinder 2 is covered with a separate cover, and the key hole 2a. Is hidden.

  According to the present embodiment, the rotation of the rotor 15 can be transmitted to the lock means 12 by the wire W, and the lock of the lock means 12 can be released, so that the auxiliary mechanical key K can be inserted. Can be disposed at any position of the vehicle (any position regardless of the position shown in FIG. 9), and the degree of freedom in layout can be improved. In addition, since the key cylinder 2 can be disposed at a position separated from the starter body 1, the antitheft effect can be further improved.

  Although the present embodiment has been described above, the present invention is not limited to this, and any device can be used as long as the auxiliary mechanical key K in the key cylinder 2 can be operated to pull the wire W and release the lock. For example, the lock unit 12 may be directly engaged with the operation knob 6 to be locked. Further, the locking means 12 may be of another form (for example, one that slides to contact with or separate from the rotating shaft and locks or releases it), and the locking means 12 in a normal state is used. The operating means may be other driving means instead of the solenoid.

  Further, in the present embodiment, the arm member 8 that operates in accordance with the rotation of the rotor 15 and releases the lock by the locking means 12 is provided. However, the tip of the wire W is directly connected without using the arm member 8. It is good also as what connects to a locking means and cancels | releases a lock | rock. In addition, in this embodiment, although applied to a two-wheeled vehicle, it is applicable also to other vehicles (automobile etc.) which employ | adopted what is called a smart entry system.

  A key cylinder having a rotor that can be rotated while inserting an auxiliary mechanical key is connected to the starter main body, and the key cylinder and the locking means of the starter main body are connected to each other by rotating the rotor. As long as the engine starting device is provided with a wire that can unlock the locking means, it can also be applied to devices having different external shapes or those having other functions added.
