Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle locking device, and more particularly to a vehicle locking device that drives a motor to activate a plurality of locking mechanisms when a received password code and a registered password code have a predetermined relationship.
[0002]
[Prior art]
As a security device to prevent the vehicle from being stolen, a password transmitted wirelessly from a portable terminal possessed by a legitimate owner is compared with a password registered in advance on the vehicle side. There has been proposed a security device that releases the lock device only when it is confirmed that the device is in the state.
[0003]
In a scooter type motorcycle, there is a shutter mechanism (hereinafter referred to as G lock) that covers a key hole of a key cylinder into which an ignition key for starting an engine is inserted, and a seat lock that locks an openable / closable seat in a closed state. Provided.
[0004]
When two locking devices are provided in this way, conventionally, a motor for releasing the G lock and a motor for releasing the seat lock have to be provided separately. For this reason, there is a problem that not only the driving device is enlarged and the vehicle weight is increased, but also the manufacturing process is complicated. In order to solve such a problem, Japanese Patent Application Laid-Open No. 2001-278156 proposes a driving device that releases the G lock and the seat lock by forward and reverse rotation of a single motor.
[0005]
FIG. 7 is a block diagram showing the configuration of the main part of the above-described prior art. When the rider operates the G lock release button 28a and the seat lock release button 28b of the transmitter 28, the transmitter releases the G lock. A release signal and a seat lock release signal are transmitted.
[0006]
In the driving device 26, when the G lock release signal is received, the motor 36 is rotated in the direction of the arrow a in the figure, and this rotation is transmitted to the wheel 39 via the worm gear 37, the worm wheel 38 and the sector gear 39a. Is driven to rotate in the direction of the arrow c in the figure. As a result, the stepped portion 39b of the wheel 39 abuts on the tip of the lever 71, and the lever 71 is rotated in the direction of arrow e about the shaft 73, so that the wire 75 connected to the other end of the lever 71 is shown. The G lock is released by being pulled in the direction of the arrow g, and the position of the pin 77 projecting from the wheel 39 is detected by the position detection switch 78 to detect the G lock release state.
[0007]
When the seat lock release signal is received, the motor 36 is reversed in the direction of the arrow b in the figure, and the rotation of the motor 36 is transmitted to the wheel 39 via the worm gear 37, the worm wheel 38 and the sector gear 39a. It is rotated in the direction of arrow d. As a result, the stepped portion 39c of the wheel 39 abuts against the tip of the lever 72 and rotates the lever 72 about the shaft 74 in the direction of the arrow f, so that the wire 76 connected to the other end of the lever 72 is illustrated. The seat lock is released by being pulled in the direction of the arrow h, and the position of the pin 77 projecting from the wheel 39 is detected by the position detection switch 78 to detect the release state of the seat lock.
[0008]
[Problems to be solved by the invention]
In the prior art described above, in order to be able to release the two locking devices with a single motor, the motor must be rotated in both the forward and reverse directions, for example, the direction of the drive current is switched. Means such as an H-bridge circuit were necessary. However, since the H-bridge circuit has a complicated configuration and a large number of elements and consumes more power than a drive circuit that rotates the motor only in one direction, a simpler circuit configuration that consumes less power has been desired. .
[0009]
Furthermore, in the above-described prior art, the two lock devices cannot be released at the same time, and the G lock must be released by rotating the motor forward, and then the seat lock must be released by rotating the motor in reverse. The two locks could not be released in a short time.
[0010]
SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle locking device that solves the above-described problems of the prior art and can release two locking devices with a single motor in a short time with a simple and low power consumption circuit configuration. is there.

[0023]
FIG. 2 is a block diagram showing the configuration of the handle lock module 12, and the controller 40a and the actuator unit 40b are the main components.
[0024]
The controller 40a includes a CPU 41 as a control unit, an RF remote control receiver 42 that receives a secret code transmitted from a remote control key, a switch input circuit 43 for inputting detection output of a magnetic pole sensor 25 described later to the CPU 41, and registration EEPROM 44 storing ID, actuator drive circuit 45 for driving an actuator unit 40b described later, switching circuit 46 for turning on / off the main switch, CPU 41 and RF remote control receiver 42 by converting battery power to logic voltage And a power supply circuit 47 that supplies the logic circuit.
[0025]
When the CPU 41 determines that the ID included in the PIN code transmitted from the remote control key and the ID registered in the EEPROM 44 match or have a predetermined relationship, the actuator drive circuit 45 as the motor control means The coincidence signal is supplied to the actuator unit 40b to release the G lock and the seat lock. The switching circuit 46 energizes the main relay when the CPU 41 determines that the ID included in the password transmitted from the remote control key and the registered ID match or have a predetermined relationship. As a result, power is supplied to the electrical components including the ignition device, and the engine can be started.
[0026]
3 and 4 are diagrams showing the configuration of the actuator unit 40b. FIG. 3 shows a locked state, and FIG. 4 shows an unlocked state. FIG. 5 is a view of the locked state of FIG. 3 seen from the side.
[0027]
A pinion gear 51 is inserted through the output shaft end of the motor 50, and a wheel gear 52 is engaged with the pinion gear 51. A worm gear 53 is formed coaxially with the wheel gear 52, and a worm wheel 54 is engaged with the worm gear 53. A cam 55 is formed on the worm wheel 54, and the cam surface formed on the side surface thereof is displaced according to the rotation angle of the worm wheel 54. That is, the actuator unit 40 b has a configuration as a cam mechanism that rotates the cam 55.
[0028]
In the worm wheel 54, an N-pole magnet 67 and an S-pole magnet 68 are embedded at positions facing each other across the rotating shaft. A magnetic pole sensor 25 for detecting the N-pole magnet 67 and the S-pole magnet 68 is provided on the substrate 23. The N-pole magnet 67, the S-pole magnet 68, and the magnetic pole sensor 25 are arranged such that the N-pole magnet 67 and the magnetic pole sensor 25 face each other and the cam 55 is unlocked when the cam 55 is rotated to the locking angle (FIG. 3). In the state rotated to an angle (FIG. 4), the S pole magnet 68 and the magnetic pole sensor 25 are positioned so as to face each other.
[0029]
The first lever 56a is swingably supported by a shaft 57a. One end of the first lever 56a is elastically brought into contact with the cam surface of the cam 55 by the elastic force of the mainspring spring 58a, and the other end is the head of the shutter lock pin 59. It is in contact with the part. The head of the shutter lock pin 59 is elastically contacted with the other end of the first lever 56 a by the elastic force of the coil spring 60. The second lever 56b is swingably supported by a shaft 57b. One end of the second lever 56b is elastically brought into contact with the cam surface of the cam 55 by the elastic force of the mainspring spring 58b, and the other end is one end of the seat wire 61. Is locked.
[0030]
The key cylinder 65 is embedded in the ignition body 22, the cylinder body 63, a coil spring 64 provided in the key hole of the cylinder body 63, a key shutter 69 that is ejected by the coil spring 64 and closes the key insertion hole 27. And a plurality of magnet sensors 66 for detecting the position of the magnet 29.
[0031]
As shown in FIGS. 3 and 5, when the cam 55 is rotated to the locking angle, the first lever 56a is swung counterclockwise, and the second lever 56b is swung clockwise. As a result, the shutter lock pin 59 is pushed into the key cylinder and the key insertion hole 27 is closed by the key shutter 69, so that the ignition key 22 is prevented from being inserted into the key cylinder. Further, since the sheet wire 61 is pushed out, the sheet 16 is fixed in the closed state.
[0032]
As shown in FIG. 4, in the state where the cam 55 is rotated to the unlocking angle, the first lever 56a is swung clockwise, and the second lever 56b is swung counterclockwise. As a result, the shutter lock pin 59 is pushed upward by the elastic force of the coil spring 60, so that the key shutter 69 is allowed to slide, and the ignition key 22 can be inserted into the key cylinder. Further, since the sheet wire 61 is drawn, the sheet 16 is unlocked.
[0033]
Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG. In step S1, it is determined whether or not a password code has been received by the RF remote control receiver. When receiving the password code, the RF remote control receiver 42 demodulates it and notifies the CPU 41 of it. In step S2, the CPU 41 compares the ID code included in the password code notified from the RF remote control receiver 42 with the ID code already registered in the EEPROM 44, and if the two match or have a predetermined relationship, The code is recognized as a secret code transmitted from a regular remote control key, and the process proceeds to step S3.
[0034]
In step S3, the rotational position of the cam 55 is detected based on the output signal of the magnetic pole sensor 25. In step S4, it is determined whether the current position of the cam 55 is the unlocking angle or the locking angle. If the locking angle shown in FIG. 3 is satisfied, the process proceeds to step S5, where a drive current is supplied from the actuator drive circuit 45 to the motor 50 of the actuator unit 40b.
[0035]
In FIG. 3, when the motor 50 rotates, this rotational motion is transmitted to the worm wheel 54 via the pinion gear 51, the wheel gear 52, and the worm gear 53, and the cam 55 rotates in the direction of the arrow as the worm wheel 54 rotates. When the cam 55 rotates, the front ends of the first and second levers 56a and 56b that are in contact with the cam surface are displaced according to the change in the distance between the contact portion and the rotation shaft, and the rear end is the shaft. Displacement about 57a, 57b.
[0036]
Returning to FIG. 6, in step S6, it is determined whether or not the cam 55 has been rotated to the unlocking angle. When the worm wheel 54 and its cam 55 are rotated to the unlocked position shown in FIG. 4 and the S pole magnet 68S is detected by the magnetic pole sensor 25, the process proceeds to step S9, where the drive current to the motor 50 is detected. Supply is stopped.
[0037]
At this time, the lock pin 59 pressed by the rear end portion of the lever 56a is lifted by the elastic force of the coil spring 60, and the key shutter 69 can be slid into the key hole. Therefore, the cylinder key is inserted into the key cylinder. It becomes possible. Further, since the seat wire 61 that is locked to the rear end portion of the lever 56b is pulled, the seat lock is released.
[0038]
On the other hand, when it is determined in the step S4 that the unlocked state is shown in FIG. 4, the process proceeds to a step S7, and the motor 50 is rotated in the direction of the arrow as in the unlocking state. Thereafter, in step S8, when it is detected based on the output signal of the magnetic pole sensor 25 that the cam 55 has been rotated to the locking angle of FIG. 3, the process proceeds to step S9 and the motor 50 is stopped.
[0039]
【The invention's effect】
According to the present invention, the following effects are achieved.
(1) Since a plurality of locking devices can be operated only by rotating the motor in one direction, it is not necessary to use a complicated configuration such as an H bridge circuit for the motor driving means. Therefore, the circuit configuration of the motor driving means can be simplified and the power consumption can be kept low. Further, since there is no need to reverse the motor, a plurality of locking devices can be released in a short time.
(2) Since the first and second levers are arranged so that a part of the projection area in the direction of the rotation axis of each cam overlaps, the area in the direction perpendicular to the rotation axis of the cam can be kept small.
(3) The first and second levers lock the locking device when the cam mechanism is rotated to the locking angle, and unlock the locking device when the cam mechanism is rotated to the unlocking angle. The device can be locked and unlocked at the same time.
(4) Provide an angle sensor to detect the rotation angle of the cam.When a legitimate password is received, if the cam is positioned at the locking angle, rotate it to the unlocking angle and position it at the unlocking angle. Therefore, since the motor is rotated to the locking angle, the locking and unlocking can be surely performed even in the configuration in which the motor is rotated only in one direction.
(5) Since the release of the vehicle anti-theft function and the unlocking of the housing portion in which the helmet or glove is housed are performed at the same time, preparations necessary for traveling can be immediately prepared and traveling can be started quickly.
