DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The cylinder lock protection device according to the present embodiment protects the cylinder lock by opening and closing the key hole of the rotor disposed in the cylinder body in the motorcycle from the outside, and when the ignition key is inserted into the opened key hole. The wireless communication for authentication is performed with the transponder built in the ignition key to prevent theft of the vehicle.
[0015]
As shown in FIGS. 1 and 2, the cylinder lock protection device includes a shutter 2, a cover 3 that covers the shutter 2, a lock unit 4 that locks the shutter 2 in a closed state, an antenna 7a, an LED 7b, Mainly composed of a substrate 7 to which a ferrite 7c is fixed, an illumination case 5 having the substrate 7 therein, and a case 6 fixed to a cylinder body 8 of a motorcycle. In FIG. 1, reference numeral 9 denotes a rotor provided in the cylinder body 8, and reference numeral 10 denotes a key hole 10 formed in the rotor 9.
[0016]
The shutter 2 is provided above the key hole 10 and opens and closes the key hole 10 from the outside. As shown in FIG. 3, the shutter 2 has a shielding portion 2a formed to have a size capable of shielding the key hole 10. The shaft hole 2b that can be fitted to the rotary shaft 11 that protrudes upward from the case 6 and the elongated hole 2c are mainly composed of a first notch 2d and a second notch on a part of the outer periphery. Two notches 2e are formed at a predetermined interval.
[0017]
The rotary shaft 11 is fitted with two rotary plate members (manual interlocking plate member 12 and remote interlocking plate member 13) while sandwiching the shutter 2 from above and below, and these rotary plate members are also independently rotated. 11 is rotatable about the center. That is, in order to rotate the shutter 2 by manual operation, the manual interlocking plate 12 is rotated by the magnet key MK, and the convex portion 12a (see FIG. 4) formed on the manual interlocking plate 12 is a long hole. In order to interlock the shutter 2 by moving within 2c, while rotating the shutter 2 by remote operation, the remote interlocking plate 13 is rotated by driving the motor 14, and is formed on the remote interlocking plate 13. When the convex portion 13a (see FIG. 1) moves in the long hole 2c, the key hole 10 is opened and closed in conjunction with the shutter 2.
[0018]
The motor 14 is remotely operated by radio waves from a remote controller 15 (in this embodiment, connected to the grip 16 of the ignition key IK as shown in FIG. 1). When the push button 15a is pressed, the remote interlocking plate 13 is rotated so that the shutter 2 is rotated in the direction to close the key hole 10, and when the push button 15b is pressed, the shutter 2 opens the key hole 10. The remote interlocking plate 13 is rotated so as to be rotated.
[0019]
In FIG. 1, reference numeral 14a denotes an output shaft of the motor 14, and reference numeral 14b denotes an operation member 14b that is fixed to the distal end of the output shaft 14a and rotates together with the output shaft 14a to rotate the remote interlocking plate 13. When a signal from the remote controller 15 is received, the output shaft 14a and the operation member 14b rotate once and stop at a predetermined position. Then, the remote interlocking plate 13 is pressed and rotated while the operation member 14b rotates once, and the shutter 2 is interlocked.
[0020]
As shown in FIG. 4, on the lower surface of the manual interlocking plate 12, a shaft hole 12b for fitting the rotary shaft 11 and a convex portion 12a fitted in the long hole 2c are formed. Has a shape 3c into which the magnet key MK can be fitted. Further, on the bottom surface of the shaft hole 12b, there are formed magnet holes 12d into which the four magnets 17 constituting the lock means 4 (biased upward by the coil spring 18) can be respectively fitted.
[0021]
When the magnet 17 is fitted into the magnet hole 12d, the closed shutter 2 can be locked. That is, when the magnet 17 is fitted into the magnet hole 12d, the manual interlocking plate member 12 is locked by the magnet 17, and the rotation of the shutter 2 interlocking with the magnet 17 is restricted and locked.
[0022]
The lock is released with a magnet key MK (lock release member). That is, as shown in FIG. 5, the magnet key MK is provided with a magnet M having a magnetic force repelling the magnetic force of the magnet 17 (arranged so that the same poles face each other). When it is brought into contact with the manual interlocking plate 12 while being matched with 12c, the magnet 17 moves downward against the urging force of the coil spring 18 by the magnetic force of the magnet M, and the locking is released.
[0023]
Therefore, the opening / closing operation of the shutter 2 can be performed by both manual operation with the magnet key MK and remote operation of the motor 14 driven by the remote controller 15, and the shutter 2 closes the key hole 10. 6 is in a state as shown in FIG. 6, and in the open state in which the key hole 10 is opened, the state is as shown in FIG. 7.
[0024]
Here, reference numeral 19 in both figures indicates a locking means that is locked with the shutter 2 in each state and restricts its operation. The locking means 19 includes the first notch 2d of the shutter 2 and the second notch. Each of the two notches 2e includes a locking member 19a that can be locked, and a spring 19b that urges the locking member 19a toward the shutter 2 side. When the shutter 2 is rotated from the open state to the closed state, the shutter 2 is configured to abut against the stopper 20 so that further rotation is restricted.
[0025]
The cover 3 is made of a nonmagnetic material (for example, aluminum die-casting), and is fitted from the upper surface of the case 6 to cover the shutter 2 and is formed with an opening 21 that allows the key hole 10 to face from the outside in the assembled state. Is. A magnet key hole 22 through which the magnet key MK can be inserted is formed in the upper right corner of the upper surface of the cover 3 so that the shutter 2 can be manually operated by the magnet key MK.
[0026]
A lighting case 5 as shown in FIG. 9 is disposed around the periphery of the opening 21 of the cover 3. The lighting case 5 is made of a resin molded product such as acrylic resin, and has a tapered portion 5a inclined toward the key hole 10 while being serrated over the entire circumference at a substantially center, and a circle to surround the key hole 10. The substrate 7 is formed in an annular shape. And at least the taper part 5a is made into light transmission, and it is comprised so that the light of LED7b (it explains in full detail below) arrange | positioned in the illumination case 5 reaches the key hole 10 side, and can illuminate.
[0027]
As shown in FIG. 10, the substrate 7 has an antenna 7a made of a coil on its upper surface and an LED 7b as a light emitting means and a ferrite 7c as a magnetic material on its lower surface. A wiring to an immobilizer 23 (see FIG. 11), which will be described later, is formed on the upper surface side of the substrate 7, and a wiring for electrically connecting the LED 7b to the power source is formed on the lower surface side. Here, the ferrite 7c is disposed on the lower surface of the substrate 7. However, the ferrite 7c may be disposed at any position from the upper surface of the cover 3 to the lower surface of the substrate 7 (including disposed on the upper surface of the cover 3). May be.
[0028]
It should be noted that other light emitting means (such as a light bulb) may be used instead of the LED 7b, and another magnetic body may be used instead of the ferrite 7c. Further, as shown in the figure, four LEDs 7b are concentrically arranged symmetrically with respect to the substrate 7, as well as arbitrary arrangement locations (for example, asymmetric arrangement) and the number (1 to 3 or 5). Or more).
[0029]
Further, in a state in which the substrate 7 on which the antenna 7a, the LED 7b and the ferrite 7c are arranged is incorporated in the lighting case 5, the lighting case 5 is filled with a transparent resin. Is molded. Thereby, it is possible to prevent rainwater and foreign matter from entering the lighting case 5 and to prevent disconnection and the like.
[0030]
As shown in FIG. 11, the antenna 7 a of the immobilizer 23 is for performing wireless communication for authentication with the transponder 24 built in the grip 16 of the ignition key IK. It is connected. The immobilizer 23 is a device for determining whether the ignition key IK is unique to the vehicle on the basis of information transmitted from the transponder 24, and preventing the vehicle from being stolen. A CPU (Central Processing Unit) 28, a power supply unit 29, an EEPROM (Electrically Erasable and Programmable Read Only Memory) 30, a communication interface 27, and a wireless unit 25.
[0031]
The CPU 28 is a central processing unit and controls the operation of the immobilizer 23. The power supply unit 29 generates VDD 31 which is a direct current power source for operating the immobilizer 23 from the battery 32, and this battery 32 is connected to the power supply unit 29 via an ignition switch 33 provided in the cylinder body 8. Has been. The ignition switch 33 is a switch that is turned on when the ignition key IK is inserted into the key hole 10 and rotated to the operating position.
[0032]
The EEPROM 30 is a storage means connected to the CPU 28, and is composed of a nonvolatile one. Instead of this, an EEPROM (Erasable and Programmable Read Only Memory), an OTP (One Time Programmable Read Only Memory), a flash EEPROM, and other power supplies A non-volatile memory with a backup function can be used.
[0033]
The communication interface 27 serves as an intermediary when the CPU 28 communicates with the engine control unit 26 for controlling engine start and stop of the vehicle, and matches the signal level and signal format between the two. . Here, since communication between the CPU 28 and the engine control unit 26 uses a serial signal (for example, a signal conforming to RS-232C), information to be sent to the engine control unit 26 is complicated and decoded from the outside. It is difficult. The CPU 28 and the communication interface 27 are connected by a bus.
[0034]
The radio unit 25 modulates information sent from the CPU 28, and the modulated radio signal is sent from the antenna 7a to the antenna 34 (see FIG. 12) of the transponder 24. The radio unit 25 is configured to receive and demodulate the radio signal transmitted from the transponder 24 by the antenna 7a, and send the demodulated information to the CPU 28. A wireless unit power switch 35 is provided between the wireless unit 25 and the VDD 31, and the power of the wireless unit 25 can be turned on / off by an instruction from the CPU 28.
[0035]
The transponder 24 operates based on a radio signal transmitted from the antenna 7a of the immobilizer 23, and transmits a signal as a response to the radio signal to the immobilizer 23 side. The transponder 24 receives a radio signal sent from the immobilizer 23 side, transmits an information generated on the transponder 24 side, a radio unit 35 for modulating / demodulating the radio signal, and the transponder 24 An authentication key generation IC 36 that performs control, an EEPROM 37 that is a nonvolatile storage unit that stores information unique to the ignition key IK, and a capacitor 38 corresponding to a secondary battery are mainly configured.
[0036]
Next, the operation of the cylinder lock protection device having the above-described configuration will be described.
When the driver wants to start the engine using the ignition key IK, the shutter 2 in the closed position is rotated to the open position by manual operation using the magnet key MK or remote operation using the remote controller 15. Then, since the LED 7b emits light and the key hole 10 is illuminated, it is easy to insert the ignition key IK into the key hole 10.
[0037]
Thereafter, when the driver inserts the ignition key IK into the key hole 10 and turns it to the operation position (ON position), the ignition switch 33 is turned on, the battery 32 is connected to the power supply unit 29, and the VDD 31 is connected to the power supply unit 29. The immobilizer 23 starts operating. When the immobilizer 23 starts to operate, various initial settings such as generation of start time data are performed. Thereafter, the CPU 28 generates random number data based on the start time data, and then transmits the random number data from the radio unit 25 to the transponder 24. Transmission data is generated.
[0038]
The transmission data is wirelessly transmitted from the wireless unit 25 to the antenna 34 of the transponder 24 via the antenna 7a and demodulated by the wireless unit 35. The wireless unit 35 generates an authentication key based on the transmission data. Such an authentication key is obtained by encrypting random number data using an encryption key which is information unique to the ignition key IK stored in the EEPROM 37.
[0039]
Then, the generated authentication key is transmitted to the immobilizer 23 side via the radio unit 35 and the antenna 34 of the transponder 24, and the CPU 28 confirms the coincidence with the authentication code separately generated on the immobilizer 23 side. This authentication code is obtained by encrypting random number data using an encryption key that is information unique to the ignition key IK stored in the EEPROM 30.
[0040]
If the authentication code and the authentication key match, a signal permitting engine start is transmitted from the CPU 28 to the engine control unit 2 via the communication interface 27. When the engine control unit 2 receives this signal, engine start control is performed and the engine is started. Thereafter, the wireless unit power switch 35 is turned off and the wireless unit 25 is stopped, thereby completing a series of authentication operations.
[0041]
On the other hand, when the driver leaves the vehicle with the engine stopped, the ignition key IK is withdrawn from the key hole 10 and the shutter 2 in the open position is closed manually by the magnet key MK or remotely by the remote controller 15. The key hole 10 is closed by rotating to the position.
[0042]
According to the present embodiment, the key hole 10 can be closed by the shutter 2 and the cylinder lock can be prevented from being destroyed. In addition, the ignition key IK inserted into the key hole 10 by the immobilizer 23 is unique to the vehicle. Therefore, it is possible to reliably prevent vehicle theft. In particular, since the antenna 7a connected to the radio unit 25 in the immobilizer 23 is provided on the periphery of the opening 21 of the cover 3 (that is, in the lighting case 5), the radio communication between the antenna 7a and the transponder 24 is stabilized. Can be done.
[0043]
Further, since the antenna 7a is formed on the upper surface of the substrate 7 and the ferrite 7c is formed on the lower surface, the ferrite 7c can effectively assist the radio waves of the antenna 7a even if there is no sufficient clearance below the antenna 7a. Therefore, the overall thickness of the protective device can be reduced. The LED 7b is disposed inside the ferrite 7c on the lower surface of the substrate 7, and the light can illuminate the key hole 10 through the illumination case 5, so that the key hole 10 is illuminated evenly. It is possible to facilitate insertion / removal of the ignition key IK with respect to the key hole 10.
[0044]
The antenna 7a and the LED 7b both need to be disposed in the vicinity of the key hole 10. However, since the antenna 7a and the LED 7b are accommodated together in the illumination case 5 via the substrate 7, the immobilizer 23 and the transponder by the antenna 7a are accommodated. 24 and the illumination of the key hole 10 can be effectively made compatible, and the size reduction can be maintained. In other words, since the wiring of the LED 7b and the wiring of the antenna 7a can be performed on the same substrate, the manufacturing cost can be kept low.
[0045]
Further, in the present embodiment, the antenna 7a is disposed on the upper surface of the substrate 7 and the LEDs 7b are disposed on the lower surface. However, these placement locations are reversed (that is, the LED 7b is disposed on the upper surface of the substrate 7). In addition, the antenna 7a may be provided on the lower surface.
[0046]
Although the present embodiment has been described above, the present invention is not limited to this. For example, the shutter 2 may be rotated only by either manual operation or remote operation. In this case, the motor 14 remote interlocking plate 13 and the remote controller 15 are not required, and therefore a cylinder lock protection device can be provided at low cost. Of course, even in this case, it is necessary to provide at least the antenna 7 a of the immobilizer 23 in the opening 21 of the cover 3. It should be noted that the present invention may be applied to the one in which the shutter slides linearly to open and close the key hole, and is applied to the one in which the shutter mechanism is directly attached to the main switch or the one attached through the bracket. Also good.
[0047]
Moreover, although the immobilizer 23 may be arrange | positioned in any location of a vehicle, if it is provided in the cover 3, for example, the wiring which connects the immobilizer 23 and the antenna 7a can be shortened. In other words, the immobilizer 23 is usually disposed in the vicinity of the engine control unit 26. However, in such a configuration, the wiring connecting the immobilizer 23 and the antenna 7a becomes long, and a break or short circuit between them (particularly a third party for the purpose of theft). (Intentional disconnection and short-circuit due to the problem) are likely to occur), but if the immobilizer 23 is attached in the cover 3 or in the vicinity of the cover 3, the wiring is shortened and intentional disconnection or short-circuiting can be avoided. is there. Further, if the immobilizer 23 is integrated with the antenna 7a and provided on the cover 3, the wiring connecting the immobilizer 23 and the antenna 7a can be minimized, and intentional disconnection, short-circuiting, and the like can be further avoided.
[0048]
Moreover, although this embodiment is applied to the cylinder lock of a two-wheeled vehicle, you may apply this invention to the cylinder lock in a ship, ATV, or a snowmobile, for example. Even in this case, it is necessary to provide at least an immobilizer antenna at the opening of the cover that covers the shutter. However, as in the above-described embodiment, the light emitting means such as LED or the magnetic material such as ferrite is interposed via the annular substrate. It is preferable to arrange the body.
[0049]
【The invention's effect】
  According to the first aspect of the present invention, when the shutter in the closed position is rotated to the open position, the light emitting means emits light to illuminate the key hole, so that the ignition key can be easily inserted into the key hole.
  AlsoSince the shutter can close the key hole, it is possible to protect the cylinder lock. In addition, when the ignition key is inserted into the opened key hole, the transponder built in the ignition key is provided. Communication with the antenna disposed at the periphery of the opening of the cover and whether or not the vehicle is an ignition key unique to the vehicle is determined by authentication, so that the vehicle can be reliably prevented from being stolen. .
  Further, since the antenna is disposed on the upper surface of the substrate, the antenna can be easily assembled to the cover.
  Furthermore, if a magnetic body is provided on the cover below the substrate, the magnetic body can effectively assist the radio waves of the antenna.
  Furthermore, if a magnetic material is disposed on the lower surface of the substrate, the magnetic material can effectively assist the antenna radio wave even if there is no sufficient clearance below the antenna, and therefore the overall thickness of the protective device can be reduced. be able to.
  Furthermore, the communication between the immobilizer and the transponder by the antenna and the illumination of the key hole can be made compatible. That is, the light emitting means needs to be installed around the key hole so as to make it easy to insert the ignition key into the key hole and illuminate, and at the same time, the antenna needs to be installed near the key hole in order to facilitate wireless communication with the transponder. Therefore, it is possible to dispose both the antenna and the light emitting means by providing them on one substrate.
[0050]
  Claim2According to the invention, since the immobilizer is attached to the cover, the wiring connecting the immobilizer and the antenna can be shortened, and the wiring can be disposed in the same cover as the antenna. Tampering with the wiring by the three parties (intentional disconnection, short circuit, etc.) can be prevented, and the vehicle can be more reliably prevented from being stolen.
[0056]
  Claim3According to the invention, since the illumination case is filled with the transparent resin and the substrate, the light emitting means, and the antenna are molded, it is possible to prevent rainwater and foreign matter from entering the illumination case and to prevent disconnection and the like. Can be prevented.
